Reset Passcode post reflash

MiMax Helium, NOT ROM specific
Was trying to get Xposed to work and bootlooped device.
Thankfully I turned on allowing fingerprint after reboot so I can get in after flashing ROM (Xeon170916-helium), gapps, magisk (14.0) and firmware (7.8.1-helium). No passcode works.. So I can use device unless I cut off 5 fingers.
I had the bootloop issue once before (RR 7.5.4-helium) and could not get in, prompting my setting the fingerprint after reboot, so I had to nuke and pave. I would rather not nuke and pave (wipe & flash clean) again. Is there a way to reset passcode back to original or new passcode?
Thanks

Guess Im SOL. I thought I say some scripting that did a proper reset on new ROM installation. Can't set SMARTlock and a few other things. Guess Ill wait for the next great ROM and wipe clean.

100% fix. You are truly the master (Mix Master ++?) and your many efforts are appreciated.

Magisk/Xposed on Stock N

So, for some reason, with stock-based flashable ROMs here on XDA, Xposed (whether it be 7.1.1 or 7.0) results in a soft brick. I've tried both Magisk Xposed and rovo's w/SuperSU, nothing seems to work.
After flashing an OTA and trying to flash Magisk it throws me an error about being unable to repack the boot image. Works fine when flashing a non-stock kernel but of course that also introduces another whole host of issues.
Does anyone here have an effective working method? The root method doesn't matter- I really just want to be able to use fingerprint gestures (Quick Actions is unstable without Xposed) and retain all of Moto's stock features/optimization.

Installing GSI ROMs on Mi8 Pro

The below is a guide to installing GSI images on the Mi 8 Pro. I specifically have experience with the PixelExperience 9.0 (Unofficial) but have had other GSI ROMs booting and working. I hope this is useful for some.
GSI (Generic System Image) ROMS can be flashed to any Project Treble enabled device. These devices have either an A/B partition layout (these allow for seamless updating as the system can boot from A or B partition) or just an A only partition layout. The Mi 8 Pro is an arm64 a only device and support project treble ROMs. You can choose from suitable ROMs listed here and here.
The instructions given below are for Android Pie (9.0). The same basic setup can be used for Android Oreo (8.0, 8.1) ROMs, but the Mi 8 Pro should be flashed with the appropriate Xiaomi base ROM first before flashing any 8 based GSI ROM
As the ROM development for the Mi 8 Pro is basically dead, I decided to buy a OnePlus 6T and sell my Mi 8 Pro. However, due to having my new OnePlus 6T stolen, and due to a lack of funds to buy a new device, I have revived my Mi 8 Pro to try to get something other than MIUI working on it. I now have The PixelExperience (Unofficial) GSI ROM running very smoothly on my Mi 8 Pro.
As the PixelExperience team has stated they will be delivering GSI images again, if there are enough of us asking, we could get better support for things like the fingerprint sensor, for a more complete experience.
Some of the below steps may be unnecessary, but are there for a complete beginner's guide to doing this and getting the right results.
Working:
WiFi
Bluetooth (with APTX)
NFC (Including Google Pay)
RIL
Mobile data (LTE / HSPDA / 3G / EDGE)
GPS
Camera (with camera built in to ROM, as well as some GCAM implementations)
Video Camera (not working on GCAM implementations tested so far - only working on Camer built in to ROM)
Flashlight
Sound / Vibrations
Face Unlock
Hotspot
Not Working:
VoLTE (I have had it working, but unable to end phone calls and problems receiving SMS messages, so reverted)
Fingerprint (There is some support. The fingerprint area of the screen lights up when trying to enrol a new fingerprint. The screen dims when a finger is placed on the sensor, and a green light us emitted from the sensor area, but it does not register the fingerprint and this is not currently working.)

How to install
Flash the latest Fastboot Global Stable Android PIE (9.0) ROM for the Mi 8 Pro. (eg. equuleus_global_images_V10.3.4.0.PECMIXM_20190712.0000.00_9.0_global_9a181f79c1.tgz) using the Xiaomi Tool.
Update: Use the latest MIUI system. The contents of the vendor partition are important. The most compatible vendor partition as of 2019-08-19 is from equuleus_global_V10.3.5.0.PECMIXM. You can download and flash that vendor independantly, if you have already set up your GSI image.
Reboot and finish basic MIUI setup.
Reboot to recovery.
[*]Format data (Wipe - Advanced - format data - confirm by typing yes)
DO NOT FORMAT DATA. Just perform a factory reset. Formatting data can cause issues and prevent booting.
Wipe Cache - Dalvik Cache and System
Reboot recovery
Use adb to push PixelExperience GSI image (img file extracted from download) and latest version of Magisk to root of SDCard. (Empty due to formatting data).
("adb push c:\path\system.img /sdcard/" and then "adb push c:\path\Magiskv19.3.apk /sdcard/")
Flash the image to system partition by taping INSTALL and then on the "Install Image" button (to toggle between flashing zip and img files). Do not reboot yet.
Flash magisk zip in the normal way (hit the same button as in previous step to show zip files to flash. (This is necessary to avoid bootloops)
Reboot, and enjoy.
You can now set up your "PixelExperience" device with your apps and settings, including registering a face for face unlock.
To pass cts validation for the safetynet and to allow service such as Google Pay to work
In Magisk, under settings - Find “Magisk Hide” and toggle the switch on
Magisk restarts. Go to Magisk Hide from the Magisk menu and ensure that...
Google Pay
Google Play
Google Play Services
Google Service Framework
Any Banking Apps
...are checked so that they cannot see Magisk (canont see phone as rooted).
Now go to downloads and install the SafetyPatch v3 module (created by hackintosh5).
Reboot.
Open settings - go to apps and notifications - and find the above apps to clear all data.
Enjoy your rooted safetynet compliant, as close to stock as possible Xiaomi Mi 8 Pro.

nice work thanks for this great notice, i will test PixelExperience, how work the face unlock? i use the finger print very much, all day, but not work i will use the facial unlock. Then i wanna know how work this.
thanks!!

Face unlock works fine. I have it paired with Pick to wake phone - so when I pick it up it wakes up to allow face unlock.
However, be prepared for some investment of time (not for face unlock).... I am a bit stuck now and cannot reproduce the above to get this working. Sometimes the results are different depending on base ROM etc.
Share how you get on and anything you may need to do to get this working.
Thanks

Nice work, i will try it .
The mi8 pro 's fingerprint is so bad which can be ignored, and the face unlock is the mostly used, hahahah
thank you very much for your work

Hi, I am waiting to unlock bootloader. Need 148hrs. Will install this. Thanks for sharing.

Quick update: There are some issues with GSI ROMs and the Mi 8 Pro. SOe of these relate to the SIMcard settings - and selection of preferred SIM for data, calls etc.
My experience shows that the vendor image from equuleus_global_V10.3.5.0.PECMIXM fixes many of these. The vendor image from the original MIUI ROM is used with the GSI system image to make the whole Project treble stuff work. I advise flashing this latest vendor image for maximum compatibility.

Do you know what issues remain after flashing the latest vendor image?

Does the face unlock on Pixel Experience work with IR camera or front cam?

I tried installing this and it got stuck on the loading screen with the Google logo. I tried following your instructions and a few other ways and couldn't get it to work at all i'm also not able to root my phone at all. When ever I try rooting my phone just reboots to twrp until I reflash the ram or flash the magisk uninstaller.
Do you have any tips, tricks, or suggestions I might try?
Thanks!

Have experienced this on occasion also.
What GSI image have you tried? after my multiple efforts, I would recommend... in this order: Omni. HavocOS, Descendant(no future updates), PIxelExperience. I am hopeful about the PixelExperience team who have made an announcement that as of August they will no longer produce CAF versions of PixelExperience, and that they will maintain regular GSI builds also. PE official GSI - I am full of hope.
Anyway, back on topic: Try this.
Follow the instructions - a few precisions:
Use XiaoMiFlash to flash the equuleus_global_images_V10.3.4.0 as a base. You can update the vendor partition once you have GSI up and running, but don't let the MIUI update to 10.3.5. Ensure you define a PIN to make sure that data partition is encrypted. (everyone should use encryption nowadays, and besides, I have had bad experiences whn using a xiaomi eu or mi-globe ROM (unencrypted) as the base
Reboot and finish basic MIUI setup. - What I mean here is to let the ROM boot, don't have to sign in to Google or Mi, but get to the home screen after the initial setup.
Then reboot fastboot and flash TWRP 3.3.0. Search for TWRP-3.3.0-0504-XIAOMI8UD-CN-wzsx150.zip.
Boot to TWRP. Make sure that you are able to decrypt the data partition with the PIN you set earlier. If TWRP does not ask you for the passcode / PIN - something is wrong. Try again. ONce all is OK in TWRP, perform factory reset. (DO NOT FORMAT DATA for the aforementioned encryption reason).
adb push the img file.
adb push the Magisk 19.3 zip.
Flash both in TWRP
Reboot TWRP
Reboot system. If it appears to hang, after 5 minutes you can force restart with the power button. I have had the ROM boot OK after second boot only?
Pretty sure that if you strictly follow the above you should get a working GSI image on Mi 8 Pro. Let me know...
It's a bit flaky to set up, but once set up, apart from fingerprint sensor not working, very stable and lovely to have the stock ish android system on a MIUI phone!
Be careful with preferred network type for mobile network as some selections have messed up incoming SMS messages for me... a dealbreaker.
What happens when you flash Magisk? What does TWRP say? Have you tried flashing Magisk, rebooting TWRP, and flahing Magisk again? It may be a TWRP version issue?

Thanks for your reply!
The version of twrp you mention is what I have used. I have not tried installing then rebooting to twrp so I try that.
When flashing magisk it usually flashes fine (I have had a couple times where it just throws an error) then when I reboot the phone will boot past the Mi logo the the Android boot logo then after 10-15 sec. it just reboots to twrp.
I was finally able to get the twrp to stick across boots by flashing twrp, signing boot image, removing twrp then reboot to Miui.
Do I need to adb push the GSI image or should it be fine to install from a USB drive?
The SMS issue isn't really a big deal for me as I use Google Fi routed through hangouts for one sim and a local sim where I'm living for mostly data and a few phone calls for the second one

Thanks so much for this post. I was completely oblivious to the fact that the Mi 8 Pro would actually be different to the Mi 8 when it comes to custom roms. When I decided on my next phone, I read the positive reviews and saw enough Mi 8 roms to be willing to make a switch to Xiaomi. Until I read your post I was close to despairing as I don't want a Xiaomi rom on my phone for various reasons (among them is the fact that I don't trust them and the way they have decided to collect user data).
I've tried to follow your guide in every step (I've also flashed the updated vendor.img), but unfortunately I have not been able to install the Pixel Experience rom on my device. I do see the boot animation but it never stops, I'm forever stuck with the Google-G and the progress bar below it. Has anyone else managed to install the Pixel Experience rom on the Mi 8 Pro? If yes, did you follow the guide here or did you do something else?
Also, in your initial post you write that we should wipe the system in TWRP but as far as I can tell GSI roms need you to wipe data, cache and dalvik cache but not the system partition (if you do it, you also don't get asked for your PIN code in TWRP any more, which - as you said - indicates that something went wrong).
Did you install a particular version of the Pixel Experience rom? Maybe that might be part of my issue?

I have try many times installing it. Didn't manage to boot it up.
Finally, tested with Miroom ROM as base then flash the system.img manage to boot up.
Don't know why it didn't boot but at lease any one who have issue booting may want to try using Miroom rom as base.

What did you do to install miroom? I've been trying to install it and it just stays on the boot screen. The only non-official from I've been able to install and boot is the unofficial LineageOS rom by fenix-UK.

Screen OC 66hz working with android 11 xiaomi_eu 21_5_20

Hi,

After flash this image i have 66HZ, but fingerprint dont work.
tested at xiaomi eu weekly android 11 from last week
have a nice day
PS i dont responde at anything, you at own response

There is a magisk module that does the same thing, but I can t use it because the fingerprint issue can t be fixed

As I can see, Magisk module flashes the img file to dtbo
Does fingerprint work after that or no more?
And how do you recover fingerprint (by restoring your dtbo backup from TWRP)?
Also, aybody tried with Xiaomi.eu 21.7.7?

After installing the module, the fingerprint scaner dosnt work. Previously, this problem could be fixed with the module, but now it does not work. I'm restoring the dtbo backup I took earlier to restore the fingerprint scaner...
Fix fp module (The latest it worked was 20.9.17)

Does this work only for miui ROMs?

It works on Official Experience latest version with working Fingerprint On Display.

I use PE+ last version(A11), when i try to 69hz-90hz i have 25-37hz. But with 66hz all works fine, no problem with fingerprint, and i have real 66hz.

Anybody have fix for the front camera?

Magisk can't find stock image, how can I upgrade and fix this issue?

I'm not sure why i have Magisk installed in a way that it cannot find the stock boot image, but that seems to be the case.
a quick search didn't turn up the stock boot image for my existing ROM version (IN2025_11_f.15)
I figure it may be easier to just update and lose root, then re-root with the new boot image, but I've had some issues doing what I thought would be easy, but turned into big issues, so before I start down this path, I wanted to ask what may be the best way to go from where I am...
(rooted with Magisk, but no stock boot.img, running build number IN2025_11_F.15, Baseband version Q_V1_P14)
...to getting onto the latest version my phone is offering (IN2025_11.F.62_2620_202301162204) and get Magisk fixed so that it then has a stock boot image, so I can update later by just uninstalling/restoring images, installing the update, then rebooting to the inactive slot, which worked fine for years.
Thanks in advance for any help/guidance doing so.

Hmmm, I've never uninstalled/restored boot image when updating. I simply disable/uninstall those modules that might cause issues (like Substratum/themes), download the full rom zip file and place it in the root of my internal and make a backup of my apps with Migrate.
Then I do the local upgrade WITHOUT rebooting. Back in Magisk I hit install after the Magisk version -> hit again install -> hit "install to inactive slot.
THEN I reboot.
Afterwards I enable/reinstall my Magisk modules and that's it.
But I just found your stock boot image in our OP 8 group too and am attaching it, in case you want to do it your way lol
XDA didn't like file upload so I put it on GDrive for you. Let me know when you've grabbed it so I can delete it

I've never done it that way myself. By just restoring images in magisk, I can do a "normal" update, from settings, and it will download just the update, in this case, about 700MB, then Install to inactive slot in Magisk and done.
This avoids me needing to find the full update to download. Probably not a big deal, but this has always worked fine in the past.
I guess i just installed Magisk incorrectly the last time I wiped, which is now causing me this issue.
I appreciate your suggestion, and perhaps that is the better way moving forward.
I didn't see your attachment, but as I'm typing this, i see you edited to say you renamed it, so I'll see if I see it now.
Thank you for your help.

Thank you, but that is the issue. I don't seem to have the stock image on the device, so I can't "uninstall Magisk" to restore the stock image.
Once I make the time to deal with this, I believe the stock image Nimueh shared will let me fix this, but I don't have time to troubleshoot this if it doesn't go smoothly, so it needs to wait a bit longer.

It normally does, but I apparently installed it 'abnormally' last time, so I didn't have/save the stock boot image.
I just need to research the best way to get the downloaded stock image onto my phone so that Magisk knows and can use it, without screwing something up, and having to wipe and reinstall everything (again).
I'm not in a huge hurry to upgrade either, but I do like to be on the latest security patches; especially considering the news with the Exynos chips' vulnerability to WiFi calling issues.

Luckily that doesn't apply to our devices though - according to the articles I've seen it only affects these devices:

Vivo S16, S15, S6, X70, X60 and X30 series.

I agree. I'm more concerned about the unpublished vulnerabilities that may exist, that we just don't know about yet.
I figure that if I keep my device updated with security patches, that's better than finding out the hard way I could have prevented an issue.

I don't use my device much and mostly at home on my wifi, so I'm not overly worried. I'm still on the last OOS 11 version mysel, mostly because 1 mod I use only exists for OOS 11. I'm sure I'll update eventually but for now I'm ok with old security patches.
