Do I need to backup persist.img? - OnePlus 8 Pro Questions & Answers

Hi. My phone says: <<Your device is corrupt. It can't be trusted and will not boot>>, bootloader is locked, I can access only fastboot and EDL. So, I'm going to use MSM tool to unbrick my phone, if I'm not going to switch, for example - from IN version to NA, do I need to backup persist.img? The problem is - I don't know how to backup it, when I even can't reach recovery, my device isn't rooted and I can go only to fastboot and EDL. Sorry for my English.

recover files after soft bick

Hi everyone, i'm struck in a dead end situation. I had a soft brick the week after upgrading to nougat and due to an incorrect setting of asus mobile manager my data were not synchronized (just the phone apps and whatsapp logs). I had a stock rom, locked bootloader, no root, no custom recovery, no usb debugging enabled. I just can enter recovery mode. If i switch on the phone it goes in bootloop, I can't enter fastboot 'cause after rebooting is in bootloop again.
With adb i'm not able to copy files, the only things i get are empy folders, i can't push files 'cause I have not the permission (surely because i don't have root).
Backup with adb is impossibile because it says "now unlock your device and confirm the backup operation..." - i'm still in recovery.
The hard way to access to internal storage is install twrp, root and unloack bootloader loosing all my data. Dead end
The easy way (if really these things work) is wipe all and buy a program like drFone or EaseUS MobiSaver for Android for data recovery post-wipe.
What do you suggest?
ps: sorry but I can't add any screeshot with insert image
Thanx

Asus ZenFone 3 Max data recovery from backup

So, I have a Asus ZenFone 3 Max WW-firmware, android 7. A few months ago the motherboard broke down, without any apparent reason, so i managed to pull a backup to my sdcard from stock recovery mode. Sent the phone to repair, tried to restore backup, didn't work (successful decryption, corrupted data).
Now, I rooted my phone, with the Magisk method, installed the patched boot in the bootloader, restored the backup. I ran the system check from the default recovery, which told me that some system files are corrupted or missing. So i supposed that the data (pictures) i want to retrieve are there, and then installed the twrp in the bootloader (ADB won't let me install it in the recovery partition, which is locked and not unlockable).
I already tried adb commands, phone is not recognized in adb, i can run the sideload mode, but it returns "error:closed", when i boot into fastboot i can only put another bootloader. Device is recognized in fastboot and sideload modes.
I have no idea of the decryption password, probably i had a fingerprint unlock at the moment, for sure no "regular password".
Any suggestion on how to recover these pics? Maybe also unpack the .backup files from pc
Thanks in advance!

I stuck on Boot Logo

I was trying to flash modified recovery image using magisk after that my phone is dead almost.
My phone don't boot in to android. I can't charge my phone because I get message on the beginning
my system is moddifyed my phone shut down automatically after 5 seconds, also i can't unlock bootloader via fastboot i get information "unlock operation is not allowed" .
I have Leeco 650x with mtk helio x27.
I only flashed modified recovery in magisk after that I disabled usb debug and oem unclock. after restart my phone I can't unlock my bootloader and I can't continue bootup to android.All I need to do is restore somehow original recovery.
But how to do that without unlocked bootloader in my situation?
I try to flash new Rome using flash tool but I have error 0xC0030003
Is here any powerful person to solve the problem.
It looks like you flashed firmware for wrong device. Settings say x650 instead of x720 (I am assuming you have x720). I think your best bet is probably the QFIL restore.

If you do not have an x720, please disregard this post.
I have 650x with mtk processor 100 procent. I only flashed modified recovery in magisk after that I disabled usb debug and oem unclock. after restart my phone I can't unlock my bootloader and I can't continue bootup to android.All I need to do is restore somehow original recovery.

You need to find the LETV X650 Scatter file. I do not know those phones very well. A X600 file may work, you will need to do a lot of research before attempting or you can damage your partitions.
Here is a link for the firmware. https://fapgem.com/video/4tnZoa0H9Q...-firmware-eui-5925s-install-via-fastboot.html
There is a chance that if you can get your PC to see the phone that you may be able to flash the stock firmware. It will not hurt to try it. Again , read extensively before doing anything.
There is a website called Android brick. They have an article on unbricking your phone but I could not access the link. Just Google, or use DuckDuck Go and search Letv X650 Scatter file unbrick.
I just now found this, which may be your solution: https://stephaniefulke.blogspot.com/2015/09/how-to-flash-unbrick-your-mediatek.html

[OP6T] fastboot erase persist

Hello ALL!
I normally don't message much because usually I can find most of my problems can be fixed by searching threads online. However, this particular case for me has been exhausting because through trial and error I have been unsuccessful in getting my 6T to boot into any rom normally.
I went from a stock T-Mobile to International version to LOS. The reason I did what I did was because I could get a IMEI or SIM to register on LOS. That worked fine on OOS 9.0.11. but as soon a I flash the latest LOS, no sim, bootloader, or IMEI detection.
I was rooted and unlocked. Now I am neither.
While on LOS, someone on another forum suggested to erase the persist partition and reflash to get the sim imei back so the phone would get service, when the phone rebooted it still didn't work and then the second time it rebooted it always gets stuck on the boot screen and never boots into the OS.
I tried to repair and reflash but was unsuccessful.
Since doing all of that, Ive reflashed using msm tool and although that was successful for OOS 9.0.11 and T-Mobile stock rom. It gets stuck on the boot screens for both.
I flashed LOS on A & B so I don't have a stock recovery.
I can't ADB anymore. I can only seem to connect via FASTBOOT but cannot seem to flash anything because the BOOTLOADER is now LOCKED.
How can I get this phone back to its original state? What ever the persist partition is. Removing it had made the phone non-bootable.
What can I do to fix? I greatly appreciate any help to get the phone operational again.
Thank you all!

- Go to the thread linked above and download the latest OOS (.13) stable.
- Download latest Magisk.
- Have the latest TWRP .img downloaded and on-hand, you will use a few times as well as the installer .zip.
- Be sure to have adb/fastboot installed.
***BACK UP DATA, YOUR PHONE WILL BE WIPED. INTERNAL SD AS WELL***
***BACK UP DATA, YOUR PHONE WILL BE WIPED. INTERNAL SD AS WELL***

- Put your phone into fastboot mode (reboot to bootloader).
- Go to the folder you downloaded in the first step and run the "flash all.bat".
- Ignore errors. If it's get stuck for more than 45 seconds, just hit enter to keep it going.
- OOS will boot. Go to settings, enable developer setting, enable advanced reboot and reboot bootloader again.
- Use "fastboot boot 'twrp-file-name'.img" to boot into TWRP.
- In TWRP, go to Reboot and changed the boot partition to the one NOT CURRENTLY enabled. In other words, switch boot partitions.
- Reboot bootloader.
- Go to the folder you downloaded in the first step and run the "flash all.bat" again.
- OOS will boot. Go to settings, enable developer setting, enable advanced reboot and reboot bootloader again.
- Use "fastboot boot 'twrp-file-name'.img" to boot into TWRP again.
- Move Magisk installer and TWRP installer from steps two and three onto the internal memory of your device.
- Flash TWRP, reboot recovery to make sure it sticks.
- Flash Magisk for root.
- Wipe dalvik and reboot system.
You will have the latest stable OOS on both partitions at this point! I literally just did this yesterday. Good luck!

Thank you but how can I flash if my bootloader is locked? Everything I try fails.
I guess the real question is: How can I get the phone to turn on OEM UNLOCK so I can fastboot unlock the Bootloader if it wont boot up the OS?
Is there a way to fix it via the msmdownload tool? Custom file maybe? I've tried the files 9.0.11 & 12 OOS files and all I get is the boot screen white ball logo circling the red ball - stuck in loop and same with stock t-mobile rom.
My friend, sounds like you need to restore your EFS partitions
... I'm trying to figure out how the hell you successfully flashed MSM tool in EDL mode and not have ALL your partitions restored. That tool is supposed to literally write the phone as it came out of the box. Also I think there are different MSM tools for each device respectively, you did use the T-Mobile one right?

My thoughts exactly. So, when it was on LOS I erased the persist partition and that really messed things up. So yes, how can I restore the partition back with a locked bootloader? Every time I've used MSM tool it fixes everything. This time no such luck. I flashed 9.0.11 & 12 and then I did the T-Mobile version. All only boot to the boot screen and hang. In doing so, I wasn't thinking if that failed and it locks the bootloader, then what? I saw an old video somewhere on a oneplus 2 or 3 where the person used the msm tool 3.0 and fixed a bricked locked bootloader phone. Similar to the fastboot method of reformatting. In the msm tool folder he had all the image files for all the partitions not sure if that the same thing as msm tool 4.0 with just one ops image file?
Anyway, is there a way to unlock the bootloader without booting into the OS? Or a way to restore the partitions via msm tool?

Try this and tell me if it works.
Have you tried this dudes stuff? https://forum.xda-developers.com/oneplus-6t/how-to/op6t-collection-unbrick-tools-t3914746

Yes, I did try that. That is what I just flashed with the msm tool. Gets stuck on the OOS boot animation.

Looks like the MSM tool. I'm going to give 9.0.13 a try but I'm thinking I may have the same problem.

Tried 9.0.13. Still gets stuck on OOS boot animation screen. There's got to be something to flash to fix this.
So you're booting EDL mode then flashing the MSM tool that exactly matches the way your phone came stock? At this point I would discontinue trying to convert it to international or upgrade the OS to a more recent version or any of that. I would focus on strictly flashing it to exactly the way you bought it.

Yes. I did flash the stock T-Mobile ROM via the MSM tool. Freezes at the pink T-Mobile boot screen. Pretty sure the partitions need to be fixed but I thought the MSM tool would do that? I guess not. Is there a more advanced MSM tool where I can see what's being partitioned or is the MSM tool not doing any partitioning and that's why the phone is having the boot problem?

I know this is a stupid question but have you tried a factory reset in recovery mode? I know its a stupid question but I did not see it asked or noted.

No stupid questions and I don't mind repeating answers to questions. I have tried that, but it does nothing. I get wipe cache or reboot to fastboot or reboot to recovery. When I choose system wipe, it takes 1 second to finish. It reboots and it gets stuck on the boot screen. Ever since persist partition was deleted it just freezes on startup and now that the bootloader is locked I cant seem to get anything to work. MSM tool I thought was supposed to fix this sort of thing but it has failed. Someone must know a way to get back into the OS so I can turn on OEM Unlock.
How do you know your bootloader is locked?

Fastboot says bootloader is locked. Shows it on the fastboot screen. Wont let me transfer any files from pc to phone. I can start the transfer process but it fails.

So you're able to enter EDL mode with a locked bootloader? How do you know your computer is seeing your device in EDL mode?
I'm going to place this here for myself for now. I'm just trying to understand your situation a little better, but this is just for later.... maybe, depending on your answer. https://forum.xda-developers.com/an...how-to-reboot-to-edl-fastboot-t3394292/page12
ALSO; If you don't mind can you link the thread that contains the original discussion where your problem began?

The point of EDL is to get around any restrictions or issues with the device, so yes, you can boot to EDL while locked. Your link will not help much because he can already get to EDL. Not to mention he will have no ADB access. Whatever he does, he has to fix it in EDL.
OP: Are you up and running yet? I am willing to try copying out my partition and sending to you.
Let me know...

Wait, I just realized that my persist.img would not work because he has no way to flash it.
Nevermind.
