[Q] Help! - Rooted Zenfone 2 (ZE551ML) bricked after OTA accidently

followed a tutorial (Cnncted's youtube clip - How to root the ASUS ZenFone 2 ) to root
Accidentally (very stupid) pressed the update option when an OTA update showed up yesterday (Jul 8 2015), and after that the phone won't start properly - stopped at in search of incredible...
No luck with trying to boot into recovery mode (power + volume up). It just vibrates once and the screen is black. Trying to flash recovery image with ADB and flashtool etc, but the MTP usb connection failed. If I connect it to the PC using the USB cable and then press the power button to turn it on (stuck in that ..."incredible" screen), device manager shows the Z200AD name with a yellow exclamation mark beside, and Asus ZenUI software will automatically start. But it's not really recognized by the PC.
So...if you have any suggestions for me to try, please let me know and that would be greatly appreciated!

p.s. This is a US version, so the it's the WW sku?

Same problem here. I have a rooted 551ML and on July 6th I received an OTA update. I installed it and I'm stuck in boot loop. I have hundreds of family pictures in the internal memory.
The good news is that I have access to boot loader and recovery.
I could not find any custom recovery for Zenfone 2. They are not out yet, right? Is there any way to copy the internal memory of the phone (that doesnt load the OS) to the SD card? Or to paste a file img.boot taken from a downloaded official rom and copy it over the corrupted one on the phone's memory?

If you can access the bootloader, you can do this:
http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835
Btw, there is a custom recovery out there (TWRP, check the Development section), but you will need an unlocked bootloader to use it in your state (I think).
US version is the WW SKU btw. Hope this helps.

Joel, thanks a lot! I will give it a try.
fingers and toes crossed...

I faced this problem too. All I did was to flash the boot.img of my version using fastboot,
Then I flashed the firmware, without factory reset I started the phone.
I was continiously getting an error "com.android.process has stopped". Ignoring that, I just backed up my whole data. Did a factory reset. Updated
Boom!! Everything was normal... I hope this helps

Just a quick update - followed the method in the link that Joel referred to, and everything worked beautifully. I did get two error messages like “the contact stopped working..." “The process android.process.acore has stopped working.” I fixed this problem by clearing the data/cache from the "contact" app, and that did the trick without a factory reset etc.
I unrooted the device using SuperSU. The fastboot screen, however, still shows a random serial number 0123456789ABCDEF. Is there a way to revert it back to the real one? I do see the real one from settings - about - status.

Isn't everyone serial number the same? mine is.

This is something that I am not sure of. Yours has been rooted as well?
I would like to know what the fastboot screen looks like before rooting.

Pretty sure rooting didn't affect my fastboot screen at all.

actually i rooted my zenfone 2 and there was an OTA and i tried to install it without un-rooting my phone. the phone would not turn on and it gets stuck in the boot animation.
the phone wasn't detected by the ADB in my pc so i thought of installing some custom recovery, thought that could help.
i tried installing TWRP but i did not unlock the bootloader and now i am not able to enter in recovery mode either, everytime i try to get in the recovery modethe phone restarts and goes to fastboot mode.
please help.

I was having a similar issue where adb wouldn't recognize my phone but fastboot was detecting it. What I ended up doing was grabbing the latest stock firmware zip from asus, transferring it to my external sd card via adapter and renamed it to MOFD_SDUPDATE.zip. Then go into fastboot (restart with volume up key) and proceed to recovery. It should automatically update your system from there. The only bummer is having to re-configure everything.

i tried it with prerooted as well as the stock rom, it did not work for me. isn't there any way to flash CM12.1 using the fastboot ?

Stuck in fastboot. No recovery... no bueno :(

So I had my ze551ml / Z00A rooted, was loving life, all was great. Then I tried getting XPosed access and didn't read up on it prior. Anyways, now my phone is stuck in fastboot, I'm able to flash partitions and all, including recovery partition, yet I cannot enter any mode but the hung ASUS logo, or fastboot. I weas even able to load CM's "upgrade to MM bootloader" package, but still the same thing only with green letters where they once were blue..... Please help, I need my beloved phone back.....

I'm not a pro but if you can access fastboot it is just a soft brick and I'm sure many people can point you on the right thread to recover it.

I've scoured the depths of both XDA and the ASUS forums, and while I've gained much knowledge of how I can possibly fix it, nothing seems to work. I go to select "recovery mode" and it instantly just boots right back in to fastboot.....

Thanks -- you can install giovix`s modder tool from general section
Set it up , use`return to stock option` --in that option , first select boot , then after- recovery(both will be stock)
You then can either
A- Reboot to stock recovery ,adb Sideload stock M -- Follow on to B-( to back-up stock before flashing)
B- Unlock bootloader again , flash twrp and root (if twrp version in modder is now 3.0.3.M4 you can flash lineageos)
---------------------------------------------------------------(if twrp version in modder is still 3.0.2.1 M - you will have to flash 303M4 in fastboot or in 3021M twrp.
1) You might be able to, fastboot flash 3.0.3.M4 immediately and forget above A&B completely
For 303M4 recovery see lineageOS in original android development section OP for download link

So I've yet to try your solution, but I do have an update, I was able to, one by one, flash all the stock files (stock as in the stuff I downloaded from asus site) and was almost able to boot to recovery, but when I got to the red triangle android, I couldn't get it to go further. I've heardf alternate key combos for proceeding from there, and tried them all, but maybe I'm just an idiot...... I'll try the giovix solution when I've got time (patience).
**when I tried flashing the cm upgrade package after that, it went back to square 1, so I gave up for the evening.**

Here's the thing. I'm super stubborn, and I think I know everything (cuz I do....) so of course I decided that I could figure something out, so I tried my way first............ didn't pan out.... anyway, I'm finding any time I flash a TWRP file, I have no access to recovery mode. Regardless if I do it manually through fastboot, or CM upgrade/downgrade or even the giovix fix (yes I tried it). My question is this, Where is there a return to stock option? of the giovix DLs I could find, I see a 'magisk root' 'TWRP' 'bootloader unlocker' and 'Xposed' tools, nothing else.... Am I missing something? or am I just skimming over that part?
I do appreciate all the help, seriously. Even if it seems like I'm not taking suggestions very well. It's moreso I don't have access to a computer most of the day, and it's not a huge priority since I went and bought a zfone 3 max a few days ago (decent phone for what it is....crazy battery life)

https://forum.xda-developers.com/zenfone2/general/tool-ze551mlmodder-t3458145
Functions:
1- Check connection status
2- Bootloader Unlocker
3- Flash TWRP 3.0.2-0 M1
4- Full-auto xposed flasher!
5- Full-auto root flasher!
5B- Full-auto root (Magisk+Phh's) compatible with 184!
6- ADB Shell
7- Return back to stock
8- Erase /system, /data and /cache for a clean upgrade
9 (HIDE)- Auto-reboot to bootloader
10- More functions inside!

well then forgive me for not downloading the correct option. I nowhere see this list among anything I downloaded, so maybe specify which is which ('full' or 'auto')....... I'm already downloading both of them again, because I'm not sure which I already had. But yea, one of the 2 only has the 4 options I mentioned.

Its not rocket science

So i finally see what you've been trying to tell me, and I returned everything back to stock, but I still have the same problem, recovery now loads but system wont boot up. I'll try loading the individual factory IMG files today, via fastboot, or should I use a zip file from Asus via recovery?

In stock recovery - choose update from adb -- adb sideload cmd is >
adb sideload MOFD_SDUPDATE.zip
Put .134 M asus firmware in adb/fastboot folder first rename it to MOFD_SDUPDATE(without zip) before this cmd above and then open up adb and type it in and hit enter.
Just in case you are trying different methods (see if this works )

I'll try it today. Last I checked it was hanging at the ”! Android” screen. But then again I'm not sure I know the combo to get passed that screen, I know it's either power and + or power and - but my only success I got into by button mashing all three keys rapidly, so, yea, I know, I'm am idiot.

EDIT"""" because i got it wrong too , i dont even think about , i just do it
It`s ->
From powered off position
Press Power and Vol +
at two vibes, release power
at boot up screen ,release vol+
in bootloader ,scroll vol up or down to and then select(press power) at recovery selection.
At dead android guy -> press vol + and power for 4 seconds -> release Vol +
You should be in recovery.

i am replying in this post since i have a similar problem, and I am as stubborn as OP. Me posting here is a big step in acknowledging my defeat at last. Hours of digging through the internet didn't solve my problem
I have changed my ifwi and dnx more times than i can remember. (my clean slate is mostly using xFSTK downloader with xFSTK_ZE551ML-sal358-amtech.vn files)
Using the above mentioned method (giovix`s modder tool) to go back to stock i still boot into fastboot, not recovery mode.
trying to unlock bootloader it says on the phone "unlock fail"
Using asus flash tool with raw files i get "gpt command failed"
Using a manual method i get the "gpt command failed" on the "6. fastboot oem partition /tmp/partition.tbl" step
in my opinion as soon as i get some kind of recovery my problems are solved. But have been working four hours on this problem with all possible solutions i could think of, nothing but frustration.
info: current ifwi 0094.0183 (wich should be M)
serial 01234........EF
and using the toolkit on "https://forum.xda-developers.com/zenfone2/general/bl-unlock-ze551ml-toolkit-t3546293" i found out my device firmware version is 198 (wich is probably not good in combo with the ifwi)
little update in a certain config (android 5 / ifwi 0094.177 / stock recovery) i can boot up untill the dead android icon, but with whatever key combo can't get past it... (vol up + power) / (vol down + power)
fastboot flash boot recovery.img (yep i am really desperate to get into recovery) doesn't even give me the dead android.
thank you beforehand!

Last paragraph with android 5 ifwi 0094.0177
Is your serial correct ?
Press vol + once is it correct?, if not you will have to xfstk first again and flash raw (twice) with temp bootloader 0094.1069
See my unbrick video for help

First of all, thank you very much for your reply!
I was not very specific there, the android 5 is not the rom (still wasnt able to flash the rom) its only the files like droidboot, ifwi, dnx, .... that i got form lolipop.
Indeed the serial is still 1234........EF (so not the correct one)
I do understand i have to flash the raw twice to get the correct serial, but flashing raw doesn't work. I get "gpt command failed" every time. (so the point where i have to restart flashtool is not even reached). Also if i try to do it manualy.
I watched your video (thanks it was my first steps into understanding how it all worked) but unfortunatly didn't work for me.
Any other ideas?

Did you get this device in this condition ?
If not, what happened so that you lost serial ?
Anyway , i have never tried this because i have ALWAYS succeeded flashing raw (twice) to correct serial BUT it may work for you.( i am not sure you have a device that can have the serial corrected due to whether its been tampered with previous ) which affects recovery and IMEI.
Usually , xFSTK is used to install temp bootloader - Its supposed to be the lowest level form of unbricking procedure and restores temp bootloader so you can fastboot after-- flashing raw in fastboot via AFT(twice) restores serial -- 1st flash approx 3mins is with incorrect serial and temp bootloader.
After a couple of mins, cmds on phone pauses on RESULT=OK on phone.
You close AFT and open AFT again , input raw and set AFT up -- press Vol+ on phone -> once, serial will be corrected and 2nd flash can be started and left until it boots into android 5 by itself.
If GPT trouble , that link may help.
There is other programmes for starting to create serial and restoring .
Usually people who use these , have to dig deep into buildprop stuff which if tampered with can end up with problem such that you have.
Good luck
see if anything here helps

Oneplus 3 Bricked - Unbrick doesn't work...

Hello guys,
my Oneplus 3 is hard bricked, I tried the methods in the Mega Unbrick guide, my device already gets shown as Qualcomm 9008 ... in Device Manager, so I started the MSM DownloadTool and it flashed anything without errors. But when the phone reboots I get a black screen and the white led is on.
I can't even boot to stock recovery (Volume down + power doesn't work and rebooting to recovery through fastboot doesn't work, too....) my bootloader is locked and all attempts to unlock the bootloader are failing with the error "remote: oem unlock is not allowed"
So at the moment I'm stuck in fastboot and nothing else works -.-
Can someone please help me?
The unbrick tool has an old firmware, can I replace the files with files from a newer firmware?
Thanks!

Have you tried the exact steps from Method 2? Maybe unzip it? If that doesn't work which is highly unlikely then there is not much you can do.

Yeah I tried it as I said, the MSM DownloadTool showed me Completed and the phone tried to boot up after that.
I'm now contacting the OP Customer Support, I've read a few times that they have other files to unbrick the phone with the MSM Tool.

Ye thats the only thing you can currently do... May i ask what you have done how did it get bricked?

I just updated AICP ota and after flashing the update my phone didn't boot up. The screen went black immediately.
So I thought that it is maybe a Problem with the ROM and I tried to go back to stock.
Flashed the stock recovery and locked the bootloader, but I couldn't boot to the stock recovery.
There it started...

Switch off the phone, connect usb ,open unbrick tool full ( method 2),Press vol up,down and power buttons same time ,tool will recognize phone then start , you must unbrick now.
NEVER LOCK YOUR PHONE.

Please read, I already did that.
The tool completed it successfully, but still black screen after a reboot.
Only the LED is flashing white.

Never but never lock your bootloader...

If recovery, boot or system partition is modified. There's no harm in re locking otherwise..

I'm assuming your device is OnePlus3 and not 3T
Okay. Firstly give a try to Oneplus3 openbeta Nougat special edition.
Oneplus3 : http://downloadmirror.co/Wa9/O2N_OBT_15801_OXYGEN_SIGN_wipe.zip
Method 1 : specific recovery for open beta24 available in Oneplus downloads
https://downloads.oneplus.com
Find legacy roms and find openbeta 24
Method 2: latest TWRP
If your bootloader is locked this isn't gonna work. But if it is still in unlocked .
Download TWRP for Oneplus3 from official TWRP site
Flash the recovery you choose using fast boot.
Now using asn command, try to flash the special edition.
Mostly this solves your issue. It helped me.
Let me know whether you face any issues.
Note: in this method you may lose every data you have on the phone. It boots up (if at all ? ) with fresh firmware and fresh storage (sometimes)

The file I gave link to is a special edition by Oneplus for Openbeta-Nougat. You can go to Nougat from any rom.
Rom: http://downloadmirror.co/Wa9/O2N_OBT_15801_OXYGEN_SIGN_wipe.zip
Specific recovery should be downloaded from Oneplus website.
You can sideload using adb or store internal storage and flash.
I tried with latest TWRP recently and it worked.
Note that all your data gets wiped if you use oneplus-recovey and asn sideload

Yes, it won't stick at 60% with this beta. I'm not the owner. It was provided on Oneplus forums. Try that one and tell me the result. It is a signed zip. So it will work on official Oneplus-recovery

Simply reboot to recovery and say yes to wipe every data.
Note1:
all your internal data is wiped in the method I suggested. I can recall there is a method to recover data only if bootloader is unlocked. If your bootloader is locked there is no other way.
Note2: your data will be formatted to f2fs file system. If you want to flash any custom ROM, YOU SHOULD CHECK COMPATIBILITY WITH F2FS in that ROM forums.
It's better to always have EXT4 file system. You can change this file system with TWRP

Even if the bootloader is locked, you can boot into the current rom and unlock simply by going to advanved options.
It is a very simple process.

TWRP recovery not working on Blackview BV9500

Hi everybody,
I try to root my Blackview BV9500 by installing first TWRP recovery. I use fastboot mode on a linux laptop to do that.
I successfully flash the twrp recovery image, but after that, the phone don't boot in recovery anymore.
It try to boot into recovery, but it reboot in normal mode a few second after.
I tried also with the cmd "fastboot boot recovery.img".
When i flash back the original recovery image, it work, i can boot the original recovery without any problem.
Does anyone have the problem?
Some one can help me to find a solution?

I, too, am trying to do this. I have not yet flashed it... I was going to use the fastboot boot command to boot the recovery kernel before permanently flashing it, to make sure it would work, and in my googling I stumbled across this post. Serendipity! [Edit 3: Although, reading your post again, I see you tried that as well and it didn't succeed for you. For me, it simply tells me remote: command not found, so how were you able to even get that to work?]
All that said... I have the BV9500 Pro, specifically for the two-way radio, so I'm going to try to keep that little tidbit of hardware working in the process. I mainly just want to tweak the menus a bit, tweak the quick settings, get root, delete the Google crapps I won't be using...
On to your problem, though, I can't help much but maybe if we post back and forth our successes and failures we might be able to stumble through it together?
First, I assume you already have unlocked your bootloader? [Edit: Honestly, I'm not sure flashing the recovery would be allowed without first unlocking the bootloader]
[Edit 2: Perhaps this thread might be of help. Different model, but often the hardwares used by manufacturers are similar enough that the same steps generally work. ]

Thank you for the link, maybe i need to flash the complete rom with the twrp recovery with spflash tools, and it will work.
I will try and let you know, but i will make a backup of my rom before flashing it!
For your problem with fastboot, maybee it's because you need to install it. You can use the command "sudo apt-get install fastboot" on a terminal window if you are on linux.
If you want to enter the recovery mode, you don't need to use fastboot, you can simply enter it by pressing Volume Up and Power buttons together for a couple of seconds when your phone is off.
When Boot Mode appears release all keys.
To flash recovery with fastboot, you need first to enable the developer mode on your phone (go to "Settings > About phone" and make 7th tap on the build number, the Developer options will be unlocked and available), and unlock the bootloader of course.
here what is the process i made to flash the recovery :
- i use the command "adb devices" to check if the phone is well connected. (response is like "BV9500S320001179 device")
- then i enter in fastboot mode with "adb reboot bootloader" (phone reboot and ask confirmation for fastboot mode)
- check with command "fastboot devices"
- unlock the bootloader with the command "fastboot oem unlock" or "fastboot flashing unlock".
- flash the phone with the twrp recovery with "fastboot flash recovery recovery.img"
- reboot the phone in recovery mode with "fastboot boot recovery.img"
Normally the phone boot in twrp recovery.
Hope that will help you too.

I am too facing this problem. In case you got any solutions please let me know too.

Yup. Already had fastboot installed for the LG G5 this phone replaced, the Galaxy Note 4 the LG replaced, the MyTouch 4G Slide the Galaxy replaced, my wife's old Galaxy S5 I used in the interims... LOL, I've got a working install. No, the "Remote: command not found" was returned from within.... Whether fastboot or adb, I forget now, but I was able to get the file to flash eventually, after reading your first post, but unfortunately the phone would not boot to it (nor Android). I thought I'd bricked it. Twice this happened. Each time, after about 5 minutes, it eventually booted to Android.
I flashed the recovery from the ROM in the link Blackview sent me and was able to boot their recovery just fine, so there's something in the TWRP that my particular phone doesn't like.

Thanks, I keep forgetting which keys to hold for recovery versus bootloader, so I use the adb command to be sure without having to keep a notepad nearby.
Clearly I don't do this as often as I used to.

Now that was something I haven't done since the T-Mobile G1 days. My understanding was that you CAN boot a recovery without flashing it first if you"fastboot boot {image filename}" but that didn't work for me either. I'm also assuming that the filename to flash can be anything because the device stores it to a partition, so it shouldn't have to be specifically "recovery-verified.img".
The recovery you have... Were you ever able to boot to it? If so, would you be willing to share a link to its download source, please?
I've got to run for a prior engagement, I'll check back later.
Thanks!

I guess i find the reason why the modified recovery image won't boot.
I find an interesting information in a post of osm0sis (https://forum.xda-developers.com/showthread.php?t=2073775) were he say : "some newer MediaTek (MTK) devices use special image signing that adds a "BFBF" pre-header signature, so images will unpack/repack but most likely won't boot unless run through their internal signing tool."
After more search, i find an interesting publication (http://www.lieberbiber.de/2015/07/04/mediatek-details-partitions-and-preloader/) witch confirm that.
They say in conclusion of the publication :
"Yes, I can confirm that SignTool is able to add digital signature information to firmware images. Signed images have an additional header “BFBF” and some fluff which SP Flash Tool checks on a secure device. Apparently some manufacturers merely used the default MTK key for signing the images, making them no better off than a typical insecure MTK device."
So we have to find another way to install magisk to root it.

Root 9500/pro
Mine rooted already....you guys can check on 4pda russian forum
Note : do not use the 17.1 version of magisk there because after reboot the device will freeze if you resboot after twrp 1st install...instead flash 17.3+ or 18+ right after first install of twrp...
EDIT : dont mind the russian language in TWRP as you can change it to english once there

you can just download latest firmware and simply backup NVRAM etc with sp flash tool also flash with sp tool, you will have then working twrp with disabled encryption. there are tons of post regarding using sp flash tool on this forum
im using same phone and did these actions on first day and did not have any problem with twrp or magisk

Hi,
I've bought this phone in Pro version. I rooted my phone using needrom.com/download/bv9500pro-bv9500-root/ and adb after unlocking bootloader. Then I failed with errors. Then I used SPFlashTool in root mode with official 2018092919_s32v63c2k_jk_pro.rar rom (I don't find it anymore on the net but 1) I got it on Blackview official forum and 2) I have the file on my own PC) with format+Download and replace recovery with TWRP from Jemmini from 4pda.ru before flashing. OK.
Then I rooted again: format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally.
Beware: TWRP is in Russian language at first boot, so to get it in English, first slide the first slide (allowing writing), then select 'Настройки', then the globe on top, then English, then 'Установитъ Язык'.
Hope this helps.
Then, this is my first rooted phone, so I plan to make a custom rom without Gapps (then maybe without Mediatek Ones and agold too) and remake all functionning with apps from Fdroid. Help needed on a manner of removing a system/vendor app properly. Help needed too to add V4A, as I could see max version supported is Nougat. I announce this here as my first post, but my project will be a full post. If someone want help please ask here or MP me
Note: an update of magisk is out (official 18.1), I installed it and my phone tells me a message that facial recognition was not working anymore then it only boots on TWRP... I reflashed it and my phone boots normally again. Wait and see...
Thanks to Jemmini from 4pda.ru again.

It'd be great to have another rom but I'm facing a problem with battery life. Basically mobile network standby drains 5000mah battery every day i turned off from developer option but still problem is there. I have checked every single post on Google but nobody has solution for this. U guys face this problem too?

New update has been released today. It solves some battery issues, but be very careful.
I installed it, having TWRP and now I'm stuck in TWRP. I've tried to wipe everything but I'm still in TWRP.
I'll try SPFlashTool ... hope it works.

Everything restored & updated.
Using SPFlashTool I flashed all files included in 2018092919_s32v63c2k_jk_pro.rar (including original recovery instead of TWRP).
After that, Android booted and then, using OTA, I updated to latest version.

The latest version is not on the forum. I installed via OTA.
But if you mean the previous firmware, there is one link on the blackview forum: http://bbs.blackview.hk/viewtopic.php?t=480235#p795494
SP Flash tools are well documented here: https://forum.xda-developers.com/showthread.php?t=1982587
And a complete list of blackview bv9500 / bv9500 pro files and instructions (in russian): https://4pda.ru/forum/index.php?showtopic=931296
Hope you find what you are looking for.

@kanadali,
for the moment I'm not facing battery drain because there is not simcard in it at this state of my modifications, sorry.
@Reflected_God,
I think this is the link I used, I use the 2018092919_s32v63c2k_jk_pro.rar rom for base.
For all others who faces big problems like me (facial recognition not working then reboot on twrp only, I could reflash my phone with SPFlashTool, the rom and twrp from Jemmini/4PDA in russian only (others don't work for me). I used Format + Download in root mode on Linux. Then format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally. Do other things. To remove gapps I disabled/force stop it before remove with TWRP. Others apps I can't disable simply remove with TWRP. I test if I encounter bugs but none for the moment. If someone wants to know what I do I've made a LibreOffice Calc sheet log, which evolve when I have time
Hope this helps
Bests Regards

Need Files or a GOOD guide. bv9500 NOT PRO.
If someone could upload the exact files that they used, and the exact same steps, that would be great. Please mention what stock version you have and a link to the image if possible as well. I've followed numerous different guides, with multiple different rom versions, multiple different recovery imgs, used sp flash tool and adb/fastboot multiple times, tried making sure everything was unlocked before each try, have all the necessary drivers, and the closest I get to a functional twrp recovery is a green line that appears at the top of the boot screen before it reboots. Ive tried going to the source, the russian site, but all of the links are 404ed. if not for me, then it would be great to just have this all in one place. Thank you please future hero.
Please include exact program versions (ex SP Flash) as well if not zips of them. I am sorry to be asking so much in one post however I truly didn't know what else to do. And I am typically very good with my google fu xD
I currently have build number BV_BV9500_V1.0_20181026. That seems to matter I believe.

I second the notion.
I have the pro model. I have considered rooting it, but honestly, the phone works well enough as-is without root (for me). However, I'd LOVE to be able to play with different ROMs on this device **AS LONG AS I CAN MAINTAIN THE TWO-WAY UHF TRANSCEIVER FUNCTIONALITY** (i.e. not some "needs-a-network-of-some-kind" "walkie talkie app" like Zello but the real UHF two-way), and I'd LOVE the ability to play with the files associated with the radio to really explore the hardware's capabilities.
Unfortunately, this phone seems more popular in [North]eastern Asia than anywhere else so I don't think we're likely to get much on this forum regarding it unless and until BV become a popular name in the western hemisphere.

TWRP - Working /data decryption on Android 9 (3.3.1-0)

Code:
#include <std_disclaimer.h>
/*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please

* me for messing up your device, I will laugh at you. Hard. A lot.
*/
As you might know, the official version of TWRP for Nokia 8 is not able to correctly decrypt /data partitions that were made using Android 9. This means, if you updated an oreo installation, you can still decrypt your data, but if you did a factory reset under Pie, TWRP will fail at decrypting. Since that makes large parts of it useless, I tried to figure out how to compile TWRP. The result is this TWRP build.
With the prepatched TWRP boot images I have been doing since October, it was required to create a new boot image for every security patch version, since otherwise the wifi driver would fail to load correctly. This new image does not have this problem, since the wifi driver is compiled into the kernel itself, and not loaded externally. This means that as of now I will not continue to upload images for new security patch images to my cloud storage. You can flash my new image on every security patch version and it will continue to work correctly.
How to install:
Reboot into fastboot mode
fastboot flash boot twrp-3.3.1-0-NB1.img
fastboot reboot
You need an unlocked bootloader for this.
After flashing TWRP you will normally boot into android. From there you can then reboot into recovery by doing adb reboot recovery, or powering off the device, and pressing the volume up while connecting it to a PC via USB.

Exactly what I was looking for!! Thanks bunches
It's still not working for me : (

I finally got it to work for me... But now I can't activate WiFi and my MAC address is reading "Unavailable"
Have already tried a factory reset, but then I still can't find any WiFi networks during the system setup

What about custom ROM's?

@THMSP
It's very interesting ?
And it's very good that you tried to make something for our device. Everyone's work will be useful I think.
In these days I also playing with Nokia system files, but only with Nokia camera. It's strange that the newest apks are not working on our device, in the beginning I was surprised, and now I took linuxct mod and made some small modifications (of course I'm a noob ?) to make it more stable. Now it's working not bad. I uploaded it to 4pda forum thread.
But that's not the point. The point is that for some ridiculous reasons HMD restricts Nokia 8 users, it's upsetting.
Anyway, you're doing great. If you don't mind, I'll add a link to your post from 4pda...
Thanks!

this is interesting, good job. I will keep an eye out for future updates regarding the custom kernel.

Great work! One great future for this Phone!

I mistakenly disabled an important system file now the phone reboots into recovery every time it finishes booting up. The problem now is that my current TWRP doesnt decrypt so now I cant get adb and fastboot to work so I can re-enable the app. How can I flash your patched TWRP so i can fix this boot issue? fastboot doesnt recognised my device when booting into download mode from inside TWRP.

Did you install the Nokia 8 fastboot driver? If no, try to install it (https://github.com/StollD/nokia-driver-installer/blob/master/out/Phone_Nokia_USB_Driver_v1.4.0.exe) and see if your device is recognized in fastboot again.

I managed to install your patched TWRP from within the previous version of TWRP. but the "recovery" partition didnt show up as an option to flash so I flashed your img file to the boot partition. When I rebooted to recovery it worked and the file system was decrypted successfully. Now the problem I have is that when I boot into the OS, Im stuck on the Nokia logo and I keep hearing clicking sounds of the camera lense every 5 seconds. Its still stuck there. Any idea how I can fix this?

Reflash the stock firmware using (N)OST. Every attempt to fix this manually is probably not worth the efford. After that, just reflash the TWRP image in fastboot.

How do I do that? The phone simply wont turn on or off at this point. Its been stuck on the "nokia" screen for the past 2 hours or so. I am just trying to figure out a way to force switching it off since the power button wont respond. Then from then on I plan to just restore a Nandroid backup then restore app data using a Titanium backup I made earlier this week. If only I could get the phone to turn off. Do you have any idea how?

Keep all three buttons pressed for multiple minutes until the phone turns off. Then boot into recovery by holding down volume up while connecting the phone to a computer via USB.

I decided to let the battery drain. I am recharging now and will attempt to do a system restore once the percentage is at 20%. Btw, I see you are very active in Nokia 8 development and are one of the most knowledgeable members on this sub-forum. So I have to ask, do you ever plan on creating a custom ROM for the Nokia 8 in the future? It doesnt seem like any other people here are interested or have the knowledge to do it.

Okay I managed to restore my system to a previous state that has a prepatched twrp 3.2.3-1 . When i followed these instructions and flashed the updated twrp, the boot hangs at the yellow unlocked bootloader screen then after about 30 seconds boots back into download mode. It wont even let me turn it off and reboot to recovery. not sure how to fix this.
EDIT: decided to switch slots and flash this image on the new slot. Same thing happened. phone wont boot and it hangs and refused to turn off no matter how long i press the 3 buttons. I tried this at the worst time now Im left without a working phone on a weekend

Again, I had to let the battery drain to turn it off.. Now im chargin it again so I can restore my previous backup. Hopefully it will be able to boot into recovery
