Develop Bugs

Lineage OS 15.0 Dev Thread [DISCUSSION]

Figured we should have a thread set up for discussion, has anyone started work on this? Maybe we should get a hangouts group started.

When does the development starts?
I don't know the procedure of ROM development. Are devs waiting for the oreo update from HTC?

Some devs already work on Oreo aosp, but it's not that easy to get it working on the 10 so that everything works. Maybe even stock will be earlier here than custom Roms like aosp and los

Don't really know about LOS but AOSP based is already here...

P.S why is there a Dev in the Title?

Is there any news?

You can't start a "Dev thread" if you aren't a dev on the project; you can only start a "Nag thread".

Sorry for unqualified question. I know the new site but I don't know where to find dev threads. If you can help me I'll be glad.

My question is why do some older phones have LOS 15.0 and we don't yet. You'd assume the newer phones get priority. My old HTC M8 has a fully functional LOS 15.

That device still has an active developer working on it. crpalmer, the user who brought 14.X to HTC 10 seems to have moved on to newer devices.

hope it will have LOS15.1

Even though Raymon left development does this mean there are no los 15 for us?

As already stated by fagyi, once he solves all bugs on aosip 8.1 he will build los.

15.1 Running flawless albeit hot sometimes!
Ladies and Gentleman,
I have been lately at the lack of instruction that some of the devs have in their OP in regards to the kernel challenges with running back and forth between nougat and oreo. All I want for my recently required and gently used HTC 10 was a simple and pure rom that I can theme and run unhindered of bloat and unneccesary tweaks without having to gut the rom with titanium backup. With that said, in my constant frustration over the past two weeks I have been able to get Lineage os 15.1 running flawlessly on my device as of yesterday with everything working including the camera and tethering. The speaker volume is a bit low, but I can live with that.
To run this as with the other 8.0 rom you have to be on nougat kernel. IF you are already running Oreo- stock or otherwise, you will have to downgrade your kernel being s-off. Generally I don't pay for sunshine but since i got a great deal on this used phone i coughed up the $25 bucks to fix my phone after deciding I wanted to run modified oreo without having to read 1100 pages of posts.
Personally I have Sprint as a provider so I used a combination of OMJs kernel flashing instructions

Now I tested this rom by flashing multiple times and I could not get any version of gapps to work but then i discovered a work around that will help. But before I get there let me explain everything I did. Some steps may be unnecessary depending on where you are coming from but i think nougat kernel is a must. I did not ruu after kernel flash.
1. Flash kernel using adb.
2. Boot straight into bootloader then Wipe and then fix persist per wonders never ceases post.
I had issues with going back to nougat kernel and had to type these instructions in the twrp terminal to get my persist back:
To fix : failed to mount '/persist' (invalid argument)
Type this in twrp terminal:
make_ext4fs /dev/block/bootdevice/by-name/persist
MAKE SURE YOU DO CLEAN WIPE all internal and format data. Fix ext4 after.
3. Resend twrp from adb.
4. Flash lineage Rom
5. Flash Magisk
6. Boot to Rom and install from Magisk G-apps systemless framework
This will not show up as being installed in magisk anymore after you install gapps. Gapps overwrites it somehow. But if you try to install gapps by itself, it will fail and crash when you boot to the rom.
7. Reboot to twrp and flash nano gapps.
8. clear cache, format data
9. profit!
Finger print scanner, Camera and everything is working. have not found any issues yet. Since I am kinda excited at getting back to LOS because i couldn't get it for my Bolt, i wanted to share with everyone else that fagyi's work is payoff.

If you are so frustrated about stuff you get for free than just stay stock and stop being frustrated.......mwuhahaha funny how the world works these days......oh and by the way, you don't downgrade your kernel, you downgrade your firmware.
Cheers, have an absolutely fabulous Sunday

I'm kinda confused by what you said. Is that ROM for Oreo firmware or Nougat?

Maybe was wrong. Maybe was Oreo firmware. Switched to this and had to go the other one. Sometimes I just go into a flashing rage and can't rememember what happened after.

I'm using that ROM build of 15.1 on my HTC 10 (Android 8.1), and it works pretty good actually. besides a few minor issues.
Unlocked Bootloader from HTCDev, Running latest TWRP Recovery, S-On (for me at least was not needed to turn this off), Latest Magisk (which seems to pass the Safetynet check) / Busybox.
I changed the Kernel afterwards to "kernel_htc_pme_aosp_tabp0le_eas_4.02-O" (from tabp0le) because it has the "performance" cpu governor that i can enable using Kernel Adiutor.
The bugs i encountered so far :
- Camera apps open slowly, except for "Open Camera" , not a big issue.
- HTC Sense Launcher doesn't seem to work, just get the famous (app has stopped) message, but maybe it's a conflict with my GAPPS installation
- Only 1 speaker works, HTC10 has Boomsound with 2 speakers on stock rom, 1 is a treble speaker, the other one is kinda like a small subwoofer for the low frequencies.
Is there any soundmod that would enable both speakers again?

There is not any mod to do that. But the dev of this ROM is working on getting the bottom speaker working.

I just saw that a new build-version is released for HTC10.

How to flash PE ROM in MI MIX2S device?

Dear every one, I really like this ROM, but how to flash this ROM?
I try to flash to use fastboot and TWRP with IMG flashIng, but after flashing them, the mobile phone will jump to Bootloader page, but when I use the same method in other ROM(like PHH and RR6.1.0)it works. My last ROM version is MIUI10-8.7.12 Globle.
details here
1.formate data
2.4 wipe
3.install and choose img file with system type.
4.wipe again
5.reboot
THanks.

If supported you can flash the image in bootloader mode.
Type in this command.
fastboot flash system nameofimage.img and reboot.

PE just wont boot for some devices. There is a whole different thread about fixing this, it may be for Huawei, but it could work for more devices. Apparently flashing a patched boot from Magisk works.

flash magisk 16.6 it will boot. but then you will have to also format data(not wipe) in twrp to disable encryption.

It finally works!
The steps I took to get it working are the following:
1. Boot to TWRP (I used version 3.2.0.1/v5 from here: https://forum.xda-developers.com/xiaomi-mi-mix-2s/development/recovery-twrp-mix-2s-t3790922
2. Format data, confirm with "yes"
3. Wipe data, system, cache, dalvik
4. Install latest Pixel Experince.img (GSI) from the thread on XDA
5. Flash magisk 16.6 directly after the image. Didn't do a reboot before flashing magisk
6. Rebooted system
7. Got many warnings that the device is not Google certified. Search for this terms and you'll find a tutorial to get rid of the messages. Simply downloaded the "device+ID.apk" from XDA and installed it. Wrote down the GSF ID and visited the mentioned page and got my device registered. Warnings are gone, play services are running perfectly fine. Here's the link to the article https://www.google.at/amp/s/www.xda...fix-device-not-certified-by-google-error/amp/
8. Rebooted system again
Works like a charm. Got everything set up to my needs. Only thing I had to configure was the navigation bar as it was hidden from the beginning. Just opened settings and toggled the navigation bar settings from one setting to the other and it appeared.
Will definitely be my daily driver from no on. Finally we can have a "Pixel" for half the price!
I'm so happy right now. Thanks to all the people who supported me and answered all my questions!

didnt worked for me rebooted into recovery i used 3.2.1-0 can you link me yours?

From this thread
https://forum.xda-developers.com/xiaomi-mi-mix-2s/development/recovery-twrp-mix-2s-t3790922
I used version 5 because in version 6 usb MTP mode is disabled.
Which rom did you come from? I came from a working official resurrection remix gsi. But I don't know if this matters as you wipe everything from the device.
Have you ever had a treble gsi running on your device? I remember installing RR after the android P beta from Xiaomi failed. I then started from scratch and installed the latest official global stable miui rom for the MiMix2S from Xiaomi without magisk and all and went from there. Don't know why but this fixed the problem with the RR gsi.
Maybe theres a problem with older mods you have done. You could try and start from zero and get the device back into the original state.
Hope it works out for you! Let us know how it turned out. Could be anyone else has some more input for you.
I know it's frustrating to flash a rom that works for others and not on your device although you have the same as them and followed every step in the tutorial. I've been there so many times that I lost count but it's always the little things that cause problems. Take your time, read some more about this whole stuff. I had to read a lot to get into this topic. Maybe theres a nother method of flashing that works for you.

Very good, great it works for you now.
Enjoy the new phone! I have it running for a few days now and so far I love it! I'm never going back to miui again! Never!
Some things are not working at the moment like Bluetooth audio to car stereo. Although it shows the song playing with the title and the correct time on the car head unit I hear no sound. Hands free calls work without any problems.
In band ringing doesn't work so I don't hear my ringtone over the car stereo. I can activate this in developer options but it doesn't stay on and doesn't work. Nevermind, this isn't important.
Haven't found many other things that I need at the moment.
Great rom, hope it gets maintained in the future and there will be a device specific rom for the MiMix2S in the near future.
Hopefully Android P in fall/winter?

Thanks for sharing so much...but I wanna know flashing Magisk 16.6 is significant or not? Why should I must flash that..caz I use bank App which is not allowed root device..Oh, I try to flash Omin ROM, but it can't get into the system..and Magisk16.6 can't be flashed in with error..

Magisk was mandatory for me because otherwise it ended up booting only to recovery.
I haven't tried what happens when you uninstall magisk after successfully setting up the device.
If you need to hide root use magisk hide, maybe that helps?

A comprehensive guide to installing custom GSI ROMs on the Mi 8 Pro

As so many others have pointed out, it is pretty hard to get any custom GSI ROMs running on the Mi 8 Pro / Explorer Edition (Equuleus). I was also absolutely oblivious to the fact that the Mi 8 Pro would require different ROMs than the Mi 8 when I bought my handset as I always check if there are custom ROMs available before I buy a new phone and there are some for the Mi 8. As far as I can tell there are no custom ROMs specifically adapted to run on our phones, but luckily enough, it is GSI-compatible or "treble-enabled". So as sad as it is that there are no real custom ROMs you can install, there is a major upside to our situation - theoretically any GSI ROM might run on it, which offers far more options than are available for the phones I have been using before I got my Mi 8 Pro. The big question is: How on earth do you get them to run on the Mi 8 Pro? If this is as puzzling for you as it was for me at first, you have come to the right place - After days and days of trial and error and growing despair, I have found a way to get both Oreo and Pie ROMs to boot and function up to a level that I'm comfortable working with and as this site has helped me so much over the years, I thought I could at least share my findings, hoping that others would be able to benefit a bit as well.
Having said that, I'll start with a list of features that won't work, so if you need them, feel free to move on (or maybe even help me find a way to get them working?). I would love for other forum members to help us expand and refine this guide (especially when it comes to the list of working ROMs) as I plan to keep this thread updated for some time.
A big shout-out goes to nealed , whose post on GSI ROMs got me started and who was OK with me laying out my information in a separate post. :good:
Not working (as of now):
In-Screen fingerprint sensor
IR face unlock ("normal" face unlock works fine)
VoLTE
Many stock Xiaomi / Mi apps won't work - you will have to find modded apks if you want to use Xiaomi's stock apps (such as the Compass app, which I rather liked but haven't found a working version for yet)
Fixed in newer Pie ROMs:
Note that Pie GSI ROMs based on earlier Phh-Treble Vanilla (AOSP 9.0) versions come with a weird ambient display bug (at least on our device). If you decide to have your ambient display set to "always on" it will flicker on and off all the time (which is why I have disabled it, it's driving me crazy when the phone is just lying on my desk and constantly stealing my attention - what does work though are the options "New notifications" / "Show when charging", so that's what I ended up with.)
Another problem with Pie ROMs I ran into was that the Android phone service would simply crash whenever I tried to manually select my network provider. I could see all available cell phone companies in my area but as soon as I would try to switch to a different provider than the one automatically chosen, the Android phone service would immediately crash.]
If none of this is an issue for you, you can expect a smooth and stable Android on our extremely powerful handset. You will be working with a ROM that can be highly customized and will also probably refrain from sending all your data to Xiaomi (which is one of the major reasons I wanted to have a rooted custom ROM and decided to accept that that also means I can't have all the features the phone normally offers - such as the very flashy fingerprint sensor).
Step-by-step instructions on how to install a custom GSI ROM
As a matter of fact, you should be aware that all data that is currently stored on your phone is lost when following this guide, so make sure you have a backup and don't ask me what you can do if you didn't create one! (short answer: nothing)
This guide also assumes you have already waited long enough and successfully unlocked your bootloader using a working Mi Account. If not, have a look here.
Step 1: Flashing an official ROM
Flashing tool - MiFlash
The easiest way to flash an official ROM that doesn't come with loads of system hogs or other "features" you don't want to have, is using MiFlash 2017.4.25.
Official ROM
Next, you will need to download a flashable global MIUI ROM. A list of all available ROMS can be found here.
Depending on which Android version you are going to install later, you want to download
Android 8.1 / Oreo: V10.0.1.0.OECMIFH (fastboot link / .tgz-file)
Android 9.0 / Pie: Try this more recent version first: V11.0.5.0.PECMIXM (fastboot link / .tgz-file). Note, however, that most of the ROMs in the GSI list have been installed on top of V10.2.2.0.PECMIXM (fastboot link / .tgz-file), so give that a try if V11.0.5.0.PECMIXM isn't working out for you.
Android 10.0 / Q: So far, we haven't been able to get any Android Q GSI ROM running on the MI 8 Pro, but there is an official MIUI Android 10 ROM available if you want a stock Android Q device:V11.0.3.0.QECMIXM (fastboot link / .tgz-file). Any ideas on how to get Android 10 GSI ROMs running on the Mi 8 Pro are much appreciated.
Once you have downloaded your ROM, extract it into a directory - I found that MiFlash was having some troubles working with directories whose directory names contained spaces, so I'd recommend simply extracting everything that is contained in the .zip-file into a directory such as "C:\flash", this way I had no trouble flashing any ROMs.
When that is done, you can start MiFlash and select the directory that contains your ROM files.
The next step is important if you want to make sure your bootloader stays unlocked (which you do): you need to select "clean all" at the bottom right of MiFlash so that flash_all.bat is selected. The default option is "clean all and lock" which is not what we want.
Should you have forgotten to change the option you simply have to unlock the phone again afterwards but as that requires a connection to the Xiaomi servers and a Mi Account that lets you do so, it's anything but ideal.
To make your phone talk to MiFlash, put your powered-off phone into bootloader mode by simultaneously pressing the power button and the volume down button and connecting it to your PC via a USB-C cable (preferably the one that came with the phone, but others should work too).
You're good to go - click on "flash" in the MiTool and watch it do its magic. It will take some time - just be patient - after 5 - 10 minutes the phone should automatically boot into MIUI and you're one step closer to installing the ROM you actually want to have on your phone.
Step 2: Installing TWRP recovery
Finding a working TWRP recovery for our phone (ideally in English) is like trying to find a miniature-size needle broken into three parts in a giant haystack. Unfortunately, our phone isn't officially supported by TWRP (yet?) so you won't find anything on their website.
What can be found, is a mixed bag, but after many many attempts of locating a proper source for TWRP image files, I finally came across this forum post.
To cut a long story short, for Android Oreo (Android 8) and Android Pie (Android 9) you want to download
TWRP 3.3.1-0607 (Firedance Edition)
as it is one of the very few versions for our device that are actually able to decrypt your data once you have set a PIN in your Android system. There seems to be a bug with some current TWRP versions that keep you from accessing your data once you have set a screen-lock PIN in your system (which is a requirement to use such features as face unlock).
So if you use a version that can't decrypt your phone (even when entering the correct PIN to enter TWRP) and you encounter a bootloop, you're out of luck: You can't access your system either from recovery or from within the system (If you have come across this post because you're in exactly this situation, you should be able to solve the problem by flashing TWRP 3.3.1-0607 on your phone to regain access).
For Android Q (Android 10) / MIUI 11, this version seems to be working:
TWRP-3.3.2B-0301 (Chinese Version)
Once you have downloaded the .img-file, the best thing is to put it into a directory that already has adb.exe and fastboot.exe in it. If you don't have such a directory, you can very easily create it by downloading and installing Minimal ADB and Fastboot.
Choose any install location you like, you will have to place your TWRP image file in your install location folder afterwards.
To prepare your phone, power it off and then put your powered-off phone into bootloader mode by simultaneously pressing the power button and the volume down button and connecting it to your PC via a USB-C cable.
Next, either start Minimal ADB and Fastboot or manually open a command prompt (cmd.exe) in the directory you have just created and enter the following two commands:
Code:
fastboot flash recovery equuleus-331-607.img
Code:
fastboot boot equuleus-331-607.img
Note that sometimes after flashing TWRP, the phone will boot into recovery twice - don't worry if you only see the TWRP screen and your phone starts rebooting straight afterwards. This is only an issue on first boot.
Congrats, you have now installed a working version of TWRP for the Mi 8 Pro. You can now also manually boot into TWRP by simultaneously pressing the power button and the volume up button on your powered-off phone.
Step 3: Installing a custom GSI ROM of your choice
Once you have a working TWRP recovery, you can install any GSI ROM that might run on our device (scroll down to my second post on this page for a list of working ROMs or click here to jump to it instead) - Prerequisite: Your ROM needs to be an ARM64 / A-Only ROM as this is the only kind of ROM our device can run.
Here's how to go about it:
Boot into TWRP, connect your phone to your PC via USB and transfer the ROM img.-file you want to install
Wipe > Factory Reset
Wipe > Advanced Wipe > System (This will prompt TWRP to ask you later if you really want to reboot - "No OS Installed! Are you sure you wish to reboot?" - which you can simply ignore, TWRP doesn't recognize that a new OS is installed after a system wipe)
Install > Install Image, select your chosen image, choose "System Image" as target partition and swipe right.
If you just want to test the image and not use any Google functionality, you can reboot now (Ignore "No OS installed") - However, this will mean that on most ROMs that don't already come with Google Apps included you won't have any Google functionality (i.e. no face unlock, no Play Store, ...) and you won't get it either if you try to install it after having already booted into your new system - so you probably want to move on to Step 4 before you reboot (unless your ROM already comes with Google Apps).
Step 4: Flashing Google Apps / Enabling Google functionality (Optional)
I'm assuming that since you're reading a guide on installing custom ROMs on an Android smartphone that it will be absolutely no news to you that instantly after installing a custom ROM and BEFORE booting into it for the first time you HAVE to install the Google functionality you want to have as there is no way of adding it afterwards. You simply have to do it right after flashing your ROM.
To flash Google Apps, you have to download them first on https://opengapps.org/.
Select the ARM64 option for the Android version you have just installed (either 9.0 (Pie) or 8.1 (Oreo)) and choose the package that best suits your need. I always go for the "Nano" package as it includes everything you can't install by yourself from the Play Store later on. This means you can also uninstall any Google App that isn't included in this package if you don't need it any longer. The bigger packages come with many more apps but if you install them now before you boot into your OS for the first time, they get turned into system apps and can't be easily uninstalled later.
Once you have downloaded the Google Apps package of your choice, you can transfer it to your phone via Windows Explorer if it's still connected via USB and in TWRP (which it should be in anyway ). Now just go to Install, select the .zip-file you have just transferred to your phone and swipe right.
Problems you might run into when installing your Google Apps:
This message or similar messages might appear in TWRP when you try to install your Google Apps package, even though you are using the correct version for your ROM (Pie ROM and Pie Google Apps, for example):
This Gapps pkg is for Android 9.0.x ONLY
Please download the correct version for your ROM: 8.1.0 (SDK 27)
Click to expand...
Click to collapse
If this happens, go to the Reboot Menu in TWRP and select Recovery to reboot into TWRP. Once you've done that, Google Apps should install without problems and recognize that you do indeed have the right Android version installed.
Many times, the System partition will also be too small to also accommodate the Google Apps package, so you will be greeted with the following message:
Insufficient storage space available in System partition.
Click to expand...
Click to collapse
If this happens to you, here's the fix:
Go back to the main menu in TWRP
Wipe > Advanced Wipe
Select System
Tap on Repair or Change File System
Tap on Resize File System
Swipe to Resize
Go back to the main menu, installing Google Apps should work without problems now
Voilà. You have just successfully gapp'ed your phone .
Step 5: Rooting your ROM (Optional)
Thanks to Magisk, rooting is incredibly easy these days. All you have to do is head over to the Magisk releases page on Github and download the latest .zip-file.
Once it's downloaded, install the .zip-file via TWRP and reboot into your OS.
For Magisk to work, you also need to have the latest Magisk Manager apk installed, which you also find on the above Github page, however I found that all GSI ROMs already have this included anyway (It appears to be included in Phh-Treble AOSP) - so all you need to do is really install Magisk in TWRP.
The preinstalled Magisk Manager will probably be outdated and ask you to update, which it can do itself. So most times, you won't even have to download the Magisk Manager apk yourself.
Step 6: Installing a working Xposed Framework (Optional)
As easy as it has become to root a phone these days, it is becoming increasingly harder to get Xposed to work as active development has been rather stalled lately. Luckily enough, someone was kind enough to unofficially get Xposed to work on Android Pie, however, this time it's a Magisk module.
Getting it to work on the Mi 8 Pro is a different matter. I have found that only certain versions do actually work and offer the Xposed functionality I have gotten so used to. If you install the specific versions I'm mentioning here, Xposed should work without problems (But as always, not all Xposed modules are still under active development and therefore won't work with Android Pie or this new unofficial version of Xposed).
To get Xposed up and running, you need to have Magisk installed already (see Step 5).
I'm currently running AOSP 9.0 (v123) and these more recent Riru package versions run fine (If you have trouble with these, check the links below) - I could only install them directly via Magisk but not in TWRP:
Riru - Core (19.7)
Riru - Ed Xposed 0.4.6.2.4529 (YAHFA)
You will also need this app installed to manage your Xposed framework and to activate Xposed modules:
The latest Ed Xposed Manager which you can download here.
For older custom Android Pie ROMs, these Riru packages were the only versions that I could successfully get working:
Riru - Core (17.1)
Riru - Ed Xposed 0.4.1.2_beta (YAHFA)
The older Riru packages can be installed directly via TWRP or in Magisk, but since you have to reboot afterwards if you install it from inside your OS, you might as well just install the two .zip-Files from TWRP directly after installing Magisk in TWRP.
The latest Ed Xposed Manager is simply an apk, so you will have to install it after booting into your system. Easy as Pie. Have fun EdXposing your system to new functionality .
Step 7: Special fixes
As I've layed out before, custom ROMs are prone to come with certain functionality missing or malfunctioning. This is especially the case with GSI ROMs that weren't developed with our specific device in mind. Nevertheless most functions will work without bigger problems right away. Some problems might still arise, but luckily there are solutions.
Sending and receiving SMS messages
After I had installed my GSI ROMs, it took me a while to realize I wasn't getting any text messages (they're not that frequent any more anyway). This is because I had to change my preferred network setting (for whatever reason). If you set it like this, everything should work as expected:
Preferred network type
4G (Recommended)
Click to expand...
Click to collapse
Bluetooth Media Streaming
I also didn't realize right away that there was a Bluetooth problem. Calls were working fine, people could hear me talking, I could hear them talking. Things got a bit weirder, when I tried to listen to music streaming from my phone to my Bluetooth speaker - it simply wouldn't work. Nada - no matter what I tried. Luckily I came across a .zip-file that worked wonders. If you install the FixGsiBTSound.zip file in TWRP that I was able to find in this XDA thread, Bluetooth media is streaming without any problems and calls continue to work.
Unfortunately, I still have to change Bluetooth Audio Codec to AAC in the Developer options every time I connect my speaker if I want to listen to music and get driving instructions via Google Maps at the same time. It automatically reverts back to SBC but after I've made the change I can have several apps stream audio at the same time, which might be a problem with my speaker that only supports SBC but I didn't have this problem with my old phone.
By the way, none of the other fixes in the thread mentioned above (specifically the VoLTE fix) were working for our phone when I tried them.

List of working GSI ROMs
This post is meant to give an overview of ROMs that can be installed and booted into on the Mi 8 Pro as long as you follow my installation guide.
To give a more complete picture, I have also included the ROMs I couldn't get to boot into a working OS.
The Mi 8 Pro is an ARM64 - A Only device, so make sure you only try to install ARM64 - A Only GSI images.
I first ended up using AOSiP (August 19, 2019 version) after having given MSM Xtended a try. However, after half a year my screen started flickering, so I reflashed a stock MIUI to send my phone back for repairs, which is when I discovered that the screen still seemed to be working. This might have been just a coincidence and the screen may still have some issues that are just not showing, but it is, of course, also possible that a custom GSI ROM could mess with your hardware.
I'm now using AOSP 9.0 (v123) with Magisk, Substratum and EdXposed and I'm really happy with it. If you're interested in why, you can read more about it here.
Please help me expand this list - feel free to test other or newer ROMs you can find via these lists on Github and on XDA .

Please note that I only tested three ROMs to see if I could get Oreo ROMs working as well. As there is no support to hide the Mi 8 Pro notch in Oreo ROMs and as I managed to get Xposed working on Pie, I quickly abandoned Oreo again .
Nevertheless, please let me know if there are any other Oreo GSI ROMs out there that you got working on the Mi 8 Pro so I can expand this section.

Special apps and functionality
Google Camera with Night Sight
Installing a modded Google Camera app helps you get the most out of your camera, especially when using Night Sight or the Playground that aren't available to most non-Pixel devices out of the box.
In order to enable the special Google Camera features, the Camera2Api needs to be enabled. This can be done by going into Magisk and downloading and installing Pix3lify which enables some other Pixel features (I found that running my phone with AOSiP and Pix3lify also gave me a much nicer Pixel-like experience to the one that Pixel Experience offered (this applies at least to the version of Pixel Experience I could get to work on the Mi 8 Pro).
To get a working modded Google camera
Open Magisk Manager and download and activate the module Pix3lify, then restart
Download a modded Google Camera apk such as BSG's MI9SE V4_P2 which can be found on this page.
There are many Google Camera mods out there and you can find a pretty extensive list here.
However, BSG's MI9SE V4_P2 was the only mod that had both the camera (including Night Sight) and the video camera working correctly, even though it doesn't seem to offer all the functionality that other Google Camera mods seem to provide.
Should you find any other modded version that might be working even better on the Mi 8 Pro, I'd be happy to hear from you.
Augmented Reality / Playground support
Even if you have Google's ARCore (Google Play Services for AR) installed on your device, it doesn't mean it's up and running. There's a built-in check that makes sure your device is officially supported and - you guessed it - the Mi 8 Pro isn't (whereas the Mi 8 is).
I'm assuming here that you've already have ARCore installed, but if you haven't, you can download and install this version: ARCore_1.12.19082605.apk.
The important steps to getting it to work, are:
Go into your Magisk Manager and install the module MagiskHide Props Config
Make sure you have a terminal app installed, I've had some good experience with Termux
Open your terminal app and enter the following commands
Code:
su
props
1 [COLOR="Silver"](Edit device fingerprint)[/COLOR]
f [COLOR="Silver"](Pick a certified fingerprint)[/COLOR]
22 [COLOR="silver"](Xiaomi)[/COLOR]
7 [COLOR="silver"](Xiaomi Mi 8)[/COLOR]
1 [COLOR="silver"](Android version 8.1.0)[/COLOR]
y [COLOR="silver"](change fingerprint)[/COLOR]
y [COLOR="silver"](reboot)[/COLOR]
From now on, your Mi 8 Pro will identify itself as a Mi 8, enabling ARCore and thus any Augmented Reality app.
You probably also want to enable your Google Camera AR feature:
If you're on Android Pie, download and install Playground_2.5build-2.6.190725076.apk
If you're on Android Oreo, download and install ARStickers_All_Pack_V1.5build-1.3.180720036.apk
Afterwards you are able to download "Playmojis" from within your Google Camera (More > Playground). However, sometimes you're out of luck and Google Play will stubbornly tell you that your device is not compatible with a selected package (e.g. Avengers: Endgame or Childish Gambino).
In this case, simply download the corresponding apk package directly from apkmirror.com and you should be all set.
More information on the Google Cam AR support can be found here.

This looks great! I'll have to try it and see if I can get it to work.

Thanks for your reply!
Are you saying you have had it boot using the steps I have outlined here? If yes, please let me know the exact version you got to boot, preferably with a link, and I will add it to the list of working ROMs. After I had finally figured out how to install GSI ROMs successfully in a way that can be reproduced, I went through the same motions every time I tried a GSI ROM and all the ROMs in my list were booting into the system, however, no version of HavocOS that I could find was booting up after going through the above steps and I tried several times and different versions, too, because some people seem to think it's a great ROM.

Havoc-OS-v2.8-20190811-phhgsi_arm64_a-Official.img was the one I had working. I have yet to find a consistent way of installing GSI ROMs. Havoc was the same. I had boot loops and also managed to boot the ROM, could not be sure that there were any differences in approach. I have tried with the latest september release of Havoc and could not get it working..
Back to LineageOS for me... Too many issues with GSI ROMs.. until I can get VoLTE OR Fingerprint working, I shall stay with LineageOS - it's really OK with MAgisk XPosed and Faceunlock... with VoLTE working well.

Thanks for letting me know the version you got to boot. I'll give it a try to see if I can get it to work using the method I've described here - if yes, I'll add HavocOS to the list of working ROMs.
I really liked the privacy features LineageOS offers but as far as OS customization is concerned I always felt it was lacking. And as I can live without VoLTE (Didn't even know what it was until I read that my new phone supports it ) and face unlock is working fine, I'm very happy with AOSiP for now, everything I use on a daily basis is working without any hitches and the system is super responsive.

You list VoLTE as not working in your OP, but say you can'r live without it. Could you please detail how you got VoLTE working on your Mi 8 Pro with AOSiP please? OR any other GSI ROMs for that matter. Thanks.
Haven't had time to try it yet, but there is another dev version of HavocOS GSI: https://sourceforge.net/projects/ha...90914-phhgsi_arm64_a-Official.img.xz/download Unfortunately, it takes me a lot of time to get my phone back to the state I want it (encrypted, decryptable by TWRP, all SD Card content present, working) when testing as I often lose the encryption and have to copy all SDcard content back to TWRP restore.... if it was just as simple as that I woudl have no prroblem, but it's not. Anyway, for those willing to try, another HavocOS GSI that may or may not work on the Mi 8 Pro.
Also, I think it important to list the vendor image and firmware images used with GSI ROMs as these can have an impact on how things work .

I've tried to streamline the ROM installation process as much as possible, if you follow Step 1 of my guide, you should be all set and don't have to worry about flashing additional vendor or firmware images. It is, of course, possible to start experimenting with vendor images as well, but the process I've outlined here seems to work fine for all the ROMs I've listed.

Thanks for your clarifications Jens. I appreciate it.

So all of these test results are with the 10.2.2 vendor. As the vendor partition plays a big role with GSI images, other vendor images may break / improve some functionality. It is important that this is understood and eventually documented with regards results of working / non working GSI images.

I have a question, why can't we just port Mi 8 (dipper) Roms? Is there anything hardware differences besides the fingerprint reader and front camera?

I would love for more users to report back their findings - the more community data we can gather, the better this guide will become over time. As it stands, I'm pretty happy that I've found a way of reliably getting all the ROMs I have listed to fully boot. When I started out, it was all trial-and-error, trying different firmware versions and GSI ROMs, also flashing different vendor images on top, and nothing seemed to work. Feel free to experiment with me and see if you can find different methods (including firmware / vendor images) of getting GSI ROMs to boot reliably.

I'm not a ROM developer but I look at it that way: As much as it's not possible to install a Mi 9 ROM on the Mi 8 Pro, it's also not possible to install a Mi 8 ROM on a Mi 8 Lite or Mi 8 Pro. You can't even install a dipper TWRP image on an equuleus device, give it a try - you will see it won't work.
Ideally a ROM would detect what kind of device you have and adjust its code accordingly. But as of now, every device needs its own specifically tailored ROM. But GSI ROMs seem to try and give us a way out of this situation.
The question I'm asking myself is why there is virtually no custom ROM development happening for the Mi 8 Pro - this is the first time I own an Android device that can't be easily customized (or unlocked - but that's a different matter).

I might normally agree with your idea but the hardware is almost exactly the same except for the finger print reader and the front camera so in theory it should be fine except for those. A different example might be installing Poco phone roms on a Mi 8 or Mi 8 roms on a Mi 8 Ursa.

I'm not saying it's beyond possible to make it happen, all I'm saying is that it doesn't seem to work as the hardware is not the same - or have you been able to install a Mi 8 ROM on a Mi 8 Pro? I couldn't even get a Mi 8 TWRP running on a Mi 8 Pro, so I'm guessing the difference does matter.

I tried with one rom and it failed to install. It gave an error about the zip not being signed or signed wrong. I modified a file in to ROM zip to remove references to dipper. (This is the process that is done to install Poco phone Roms on a Mi 8). I'm not sure how to modify the rom zip and re-sign it so it installs. Unfortunately I don't have much time right now to experiment as I'm busy with school.

Sounds like an interesting route, so if you follow it through and get it to work, please let us know how you made it happen.

Testing day yesterday, I am currently running HavocOS, with the just released chinese Xiaomi V11.0.2.0.PECCNXM vendor.
I believe that to get it working, SELinux needs to be set to permissive.
Steps taken to boot:
1. Flash 10.3.4 ROM using Xiaomi Flash tool - wiping and cleaning everything, including data and SDCard.
2. Boot and set passcode.
3. Reboot to Bootloader
4. Flash recovery-TWRP-3.3.0-0504-XIAOMI8UD-CN-wzsx150 TWRP.img to recovery partition
5. Boot recovery-TWRP-3.3.0-0504-XIAOMI8UD-CN-wzsx150
6. Factory Reset
5. Flash Havoc-OS-v2.9-20190914 (thread, download
6. Flash permissiver-v4 by erfanoabdi for GSI images
7. Boot
8. Upon reboot to recovery - wipe cahche / dalvik, reboot recovery, then reboot system
9. If you are sent back to recovery. Just reboot - it will boot eventually.
10 Subsequently, from TWRP, resize system partition and flash gapps (yes, you can do this and everything works fine. I have done this on plenty of occasions. It is also possible to invoke the android one time setup wizard if you need that to restore from a backup etc.).
11. Flash Magisk 20.0
12. Flash PolarKernel (see this section for download and details)
HavocOS allows:
Using gesture navigation (I use OnePlus gestures) - native feature
Using Face unlock with the option of dismissing the lock screen automatically - native feature
Hide the clock (great for our notched devices (for me anyway as I have a clock widget on the home screen anyway)) to gain valuable screen real estate - native feature
Battery circle icon - native feature
Great theme options built in
Many more features.
I am reaching out to some devs to see if I cannot cook this for our Mi 8 Pro. I would dearly love to get the under screen fingerprint working. On one hand others have tried and failed. On the other, I'm not sure how much effort has gone in to the trials - as this is not exactly the most popular device on the planet. Not many devs have it.
However, with fanix-uk working on LineageOS - and possibly the FP sensor - as well as the possibility of having VoLTE and infrared face unlock (as is present in LineageOS for Mi 8 Pro) working - this would be my perfect setup.
Despite not having VoLTE (I may do some tests today) I am considering staying with this setup as it really is great. Time will tell...

[HELP] WiFi keeps disconnecting and reconnecting

My XT1795 is on stock 8.1 with unlocked BL, TWRP and magisk (I haven't installed any modules though). I am facing this weird issue since an year, the WiFi randomly keeps disconnecting and reconnecting automatically every 10 to 15 mins. I am sure that it has nothing to do with my WiFi router as I face the same issue when I am connected to mobile hotspots or any public or private network. I tried resetting the wifi and network settings, restored the device quite a few times, and also reflashed the stock rom but the problem still exists. The most recently that I reflashed the stock rom was a month ago, i didn't face any issue for the first 15 days but now it's back again.
Can someone please help me?

Try using a different kernel. But make sure that stock 8.1 is supported

You have root right? Try taking some logs until WiFi crashes. Then wait a couple of seconds before stopping log recording. I will try to look into it.

Please have a look at the logcat, this morning while generating this log the wifi network ([email protected]) disconnected and reconnected atleast 3 times. Even after the reconnection, most of times I am not able to access the internet, I have enable airplane mode, then enable the wifi again or reboot the device. I am sure there is no problem with my router because, I face the same issue when ever I connect to any network be it a mobile hotspot or railway public network.

I would personally suggest 2 things
1. Install lineage 15.1
2. Re-install stock
Alternatively to 2:
Factory reset, could fail though due to magisk and force-encrypt

This problem started after I unbricked my phone few months ago. I flashed an older version of bootloader on my XT1795 which lead to a complete breakdown, the phone was unable to boot, I had to flash mmcblk0.tar and this rom on a 32GB sd card and booted from it so as to flash a new stock rom on the int storage. After all those efforts the phone booted up but I started having this WiFi issue.
I'll try installing lineage OS because , I have tried reinstalling stock 2 times and even factory reset-ed the device. Thanks alot for responding.
Edit : I have flashed the LineageOS 15.1, will update if the problem persists.

The wifi drops are more severe on lineage 15.1. Most of the times there's no internet access even while wifi is connected. Please have a look at the new logcat file.

I am being forced now to roll back to the stock rom from twrp backup.

When it is like that even on lineage, try downgrading to nougat and see if the error persists, I also have this problem now btw... I'm on Android 9 though
If the error doesn't persist, upgrade back to Oreo. And see if it's fixed, if not, then I'll have to try around a little bit by myself
Also, me being on Android P with Radium, it isn't really a kernel issue.
I just cant decide what it is,
Also, don't use the "stable" build advertised pretty recently in jarl's lineage 16 thread, it isn't stable
(Bruh)
I will try downgrading to Oreo and see if the error persists for me.

1.
Now I flashed stock 8.1 (fresh flash) on the lineage 15.1. The wifi problem is still there. Like you said, the last way could be downgrading to Android Nougat but I am scared it could hard brick the device. Why I am saying this is I did a downgrade 7-8 months ago, which bricked the phone and led me to Blank Flash 7.1 srock rom to finally make it boot, it was then this wifi issues started. It was a disaster, later I came to know that downgrading bootloader from from a new version of rom to an older version will mostly end up in dead devices. :highfive:
2.
So do you still think I need try downgrading once again ?
3.
I am fed of this phone now, I was planning to get a new one but everything in India is locked down till 15th April. I only have this flashing time till that date, from 16th (could be even 10th) I have to attend office.

We have one last resort,
G. S. I
If that doesn't work, then it's due to isp's being overloaded from all the streaming which is happening.
For me, it started when testing an "stable" (*cough cough* it isn't *cough cough*)

Install latest , non wiktor build of lineage 16.0 builddate
20200208
Or the gsi "optimized" 2019070X build

Please try to run this command in terminal emulator, while wifi is on.
Code:
su
killall wpa_supplicant
This will kill all the active connections and reconnect to current network, I read on linux foums that this fixed the wifi issue at least temporarily.

Okay okay. I got the.. ahem... "Fix" for the issue.
Basically, when reinstalling almost everything (except firmware)
It just fixed itself? I dont know how it just did.
Try reinstalling Lineage 15.1 or 16 (jarl's builds, wiktors cause more problems aka Lineage 16.0 v0.16 instead of 0.17)
And then installing a GSI of choice. If you didnt look that up yet, basically, you know how on a PC, no matter the hardware, you can install windows on it without device specific ****? Yeah that's project treble, allowing installation of updates and ROMs using .img files.
Luckily, our Lineage 16.0 builds (and only those) have full support for treble, so, just download a rom of choice, RR for example, extract it using an application like RAR and then wipe ONLY
/System & /Data NOT FORMAT
Wipe>advanced wipe> select system and data
This won't erase Internal storage just uninstall all apps and stuff
And then head to where you extracted the .img file and select "flash zip" in the bottom right corner
It should now switch to: "install Image"
And the extracted file should show up.
Select it, select "system image" and flash
Don't worry about it saying: " NO OS INSTALLED" And blah blah blah. The phone will take care of it, unless it crashes, then the rom isn't compatible with our specific device.

If the launcher for example is lagging, try adding this line
Sys.use.fifo_ui=1
Into build.prop and rebooting, maybe that makes it better

Thanks to exynos5420 team for the right kernel

Thx @Valera1978 that's great news.
Gonna test today.
Edit 6h later first impressions:
Coming from Lineage 14.1 Vanilla with TWRP 3.4.0-0.
Backed up everything, full wipe plus data format.
Installing purely the ROM with TWRP 3.4.0 led to "Error 7" 3.3.1 did the trick.
Made a reboot to check if it starts.
Noticed screen failures in form of small black bars/stripes which vanished after a few seconds when I let the screen settle.
(Appearing very often even now after full installation of everything I need.)
Rebooted to TWRP and installed BiTGapps (prefer them to opengapps as they are even smaller than pico) and Magisk.
After each flash wiped cache/dalvik of course.
Installed Nova prime (dark mode) and all my other apps.
Camera doesn't work with Lineage App (as said) but does with opencamera from f-droid.
Screenshots neither but using Quickboot is a workaround when activated in its settings.
When writing text and correcting failures the magnifier shows only a white field with now text in it even when dark mode is off.
Great work @Valera1978 will carry on testing.
Edit 18h later:
Firefox seems to have problems with it, doesn't often even open its add-on page or urls.
Lightning browser has no probs.
Only one sudden reboot until now.
Edit 24h later:
Tried to upload a pic with the screen problems but didn't work.
Mostly occuring when switching from portrait to landscape (reproducible).
Because of the Firefox problems I've tried the 79 version but starting it resulted directly in a reboot (reproducible).

I'm surprised there aren't more responses
Can confirm TWRP 3.3.1 is the latest recovery to work. Doesn't seem to work with 3.1.1
Can't change wallpaper. Not sure why. I have to go to live wallpaper to get the default one back
Ok Google needs to be installed manually
I get security flags from SELinux and Public trust certificates. Probably because the release is so early
Overall it's not bad for a Pre-Alpha release.

First of all: an awesome thank you to Valera1978 since I was expecting a newer version than 14.1 a long time
Have the same issue with the wallpaper change and some flickering in the display. Installed nova prime too but can`t close all apps in task manager only each manually single (wipe up)
I am eager for the next version and improvements :fingers-crossed: and willing to give further feedback.
THX a lot for your passion

the current version is rather a technical build for testing (public, the most stable, there were already about 40-50 internal builds for fixing bugs and checking various things).
In any way - lineage 17.1 coming soon (later today), release build done, on tests right now. And I like it much more, then technical 16.0 build.

I tried 16 and I like it. Looking forward to 17.1. Thanks for saving the P900 from an early grave you are and have been the best ?

i will try this process for the first time. Is there a video tutorial? thank you.

This ROM will probably not be in development any further as the brilliant dev @Valera1978 is already working on a 17.1.
About a video I don't know. Searching in YouTube might help finding out
Here is a very good description which I followed from @thompatry who's ROM is very stable, has a working camera (skype) and gets regularly updated.

Download it to SD.
As he quoted install a TWRP first to exchange the stock recovery.
Easiest to do is use a windows PC with Odin version 3.13.
Battery fully loaded before starting.
1.Download TWRP 3.3.1 for v1awifi from twrp.me but choose the tar version and save it in Odin folder.
2.Get P900 into download mode (turn it off, then press buttons Pwr, home, vol- altogether).
Will give you a warning but continue with vol+.
3.Start Odin then connect P900 to PC and check in Odin if a field on the left turns blue (com+).
4.Uncheck "auto reboot" in Odin.
5.Flash TWRP 3.3.1 with Odin onto P900 putting the downloaded TWRP file in "AP" field in Odin.
When Odin says "Pass" all is fine.
6.Turn P900 off with pwr button but press afterwards directly home and Vol+ together as it automatically reboots.
Then you access the new recovery.
If you fail the Samsung recovery gets reborn and you have to repeat steps 2-6 again but that does no harm.
Save all what is possible with TWRP to external SD using Backup.
Then wipe everything in TWRP (except SD ), select "format data" after that.
Select install and choose the ROM from SD.
Test if system starts. Might take a while.
If you want to use Google apps, download Gapps from opengapps (choose ARM, 7.1 and pico) and save it in advance to SD.
If system starts, turn it off, restart to recovery (pwr, home, vol+) and install Gapps.

Hi everyone, I hope you are all safe and well.
Just a quick question, do I use the latest version of TWRP for my P900 (note pro 12.2 wi-fi). There are versions on the website which are later than the 3.3.1 version in this post. At the moment my version is 1.22, so this is really old! This was obviously installed and I did the flash to 14.1.
Like I say, at the moment, I am using LineageOS 14.1 with an old security patch level (September 19) because I cannot seem to update it. I have tried the auto update, this fails and I have also tried to manually apply but this also does not work.
I was wondering whether it was time to upgrade to version 16 or 17.
I'm not an expert on this by any means and I recall I did struggle with some error message when trying to update to I think at the time line Lineage 15.
Any comments or suggestions would be much appreciated.

@mattgod69 auto updater I don't use/like at all.
My suggestion is download TWRP 2.8.7-0 as zip and flash this with your TWRP. It is the latest zip released.
From that on it can use img files and you can update further to 3.3.1 or higher.
For me 3.4.0 was needed to flash @Valera1978 LOS17.1.
3.3.1-0 for LOS14.1 by @thompatry which's Vanilla (version 20201215) I use for here camera is working instead of being on LOS17.1.

Thanks for the reply @bmwdroid, i was talking about the app which is version 1.2 (doh)... i have just booted into TWRP and i have version 3.3.1. So if you are using the same tablet as me, what would you upgrade to or would you leave it as is. Also, do you think i need to update the security patch level? Cheers and apologies if these are silly questions.

Mine is a P900 v1awifi.
I suppose that the app 1.2 refers to the TWRP app which I don't use and I've always read warnings to install it so I never did.
It is said that it sometimes causes problems when flashing.
And imo it's not needed anyhow.
If you need camera working for skype or else I recommend to flash the latest LOS14,1 mentioned above.
https://download.exynos5420.com/LineageOS-14.1-Deathly/v1awifi/
with the deathly adiutor built in
or
https://download.exynos5420.com/LineageOS-14.1-Vanilla/v1awifi/
which is a plain android system
The development of this LOS16 seems suspended as the dev is already working on LOS17.1 which I've tested, but as said has no working camera.
Therefore I can't say much about its stabilty but it worked with Bitgapps and Magisk for 4-5 hours until I switched back to LOS14.1.
If you want to test it: I had to upgrade TWRP to 3.4.0 to avoid "Error 7".
To go back to 14.1 I had to downgrade to 3.3.1 first.
Questions show that someone is willing to learn which should be appreciated.

Mine is a P900 v1awifi.
I suppose that the app 1.2 refers to the TWRP app which I don't use and I've always read warnings to install it so I never did.
It is said that it sometimes causes problems when flashing.
And imo it's not needed anyhow.
If you need camera working for skype or else I recommend to flash the latest LOS14,1 mentioned above.
https://download.exynos5420.com/LineageOS-14.1-Deathly/v1awifi/
with the deathly adiutor built in
or
https://download.exynos5420.com/LineageOS-14.1-Vanilla/v1awifi/
which is a plain android system
The development of this LOS16 seems suspended as the dev is already working on LOS17.1 which I've tested, but as said has no working camera.
Therefore I can't say much about its stabilty but it worked with Bitgapps and Magisk for 4-5 hours until I switched back to LOS14.1.
If you want to test it: I had to upgrade TWRP to 3.4.0 to avoid "Error 7".

Thank you for the detailed response, very helpful.
I dont really use the camera with my tablet, but i might, so its probably best to wait til 17.1 is working. The tablet is really just a browsing device i use beside my bed, its not an everyday machine.. so i am willing to try new things and play about with it.... it also does not matter if it is wiped accidentally etc.
i have to say it has been overall much better with 14.1 installed, far better than the stock OS. It is faster and more responsive.
Presumably I need new google apps etc download any new OS? If i install the latest LOS 14.1 do i also need new gapps etc? Is this OS much better than the one i have?
I do not know what Bitgapps and Magisk are?
Many thanks for all your help.... this community is great because even though i have done this a couple of times on different devices, there are long time gaps between doing it and it is still quite scary because i dont want to brick the device!

Just looked at Magisk... is it not a good idea to have this in any event? it looks like this would be earier to install later OS like LOS17.12? Is this right?

@mattgod69 BitGapps are an even smaller Google Apps version than Opengapps pico.
I use them on Android Q, as opengapps weren't working properly at that time being.
I don't use Google TTS and always had to block it when using opengapps.
Magisk is an equivalent to SU which is no longer continued.
It's neede for all apps needing root like AFWall, DeviceInfo and many others.
If you or your tab are happy without there's no need flashing it.
It causes no probs when switching ROMs as long as it's a clean flash.
Even updating ROMs dirty works on mine.
If you already had LOS14.1 installed and google apps as well you don't need a newer gapps version when updating dirty as gapps get updated by Google itself.
When flashing cleanly I recommend a newer gapps version but you can use any old (designed for the specific android version) as well.
Only setting up might take longer as the gapps will be updated automatically as soon as they find an internet connection.
The newer version of LOS14.1 will imo only be different in patch level nothing else.
Hope I didn't overlook a question.

i think i am going to try 17.1... i think most issues have been sorted now?
i did have some questions before i do this which i have put in another post.....
Also, how do you do a dirty install... is this where the cache etc is not wiped?
would you update TWRP to 3.5.0. (the latest one). I assume this can be done from the program in recovery mode?
Many thanks for your help and advice.

Updating TWRP can be done with itself.
Working up- and downwards.
Just select "install" switch to "image" choose the file and select "recovery".
Afterwards reboot directly into the new recovery.
