Installed pixel experience today I don't see the IMEI information. Any idea how to get it back?
I was also trying to encrypt the phone use no-verity-opt-encrypt. But that somehow didn't work. I erased the data again and reflashed pixel experience 11. Anyone knows how to get back original imei?
Have you backed up phone's /EFS partition - where IMEI and other networking stuff is stored - before flashing the Custom ROM?

No backup. Now the wifi also seems to be gone after reflashing pixel experience! #help

Hey all,
I restored a backup of my old phone made in TWRP – a full backup, including Boot, System, Data, Cache & EFS – onto a new D850 I got. Both the old phone and the new one were able to connect to AT&T before this.
Now the new phone, with the restored backup from the old one, displays a network searching icon indefinitely upon reboot.
Any thoughts as to how to fix this?

Why did you restore a EFS back from your old phone to your new one? Unless you backed up the EFS from your new phone there may not be a way to fix this. EFS Is different for each phone you should never restore an EFS from a different device.

My *guess* is that I should not have overwritten the new phone's EFS with the old phone's? I think I backed up the EFS of the new phone before doing so; will restoring it fix my issue? If not, how screwed am I?

See if you have a backup of the new phones EFS try that and report back. If not it's pretty much a WiFi only device.

I restored the new phone's original EFS, and all is well.
FWIW, my reasoning behind flashing everything from the old phone to the new was that is what it said to do in every guide I read about transferring from old to new. I didn't realize EFS was supposed to be excluded; I didn't realize the EFS from one phone would be incompatible with another
In any case, crisis averted – thanks for the confirmations along the way

It's not that the EFS is not compatible. But the EFS stores info like IMEI etc. you can't have two phones with the same imei. Each EFS is different. When restoring you don't have to restore every thing though. I'm glad you had a backup! As without that it pretty much would had been an wifi only device. Your very welcome .

Hi guys, here's my dilemma:
Samsung Galaxy S6 with Android 5.0.1 or 5.0.2 (I forget which)
Rooted & Full device encryption
Want to recover my information if possible; no factory reset
My questions:
Is there a way to fix a system to recover my data on a rooted & fully encrypted device?
Would flashing work, and how would I go about the recovery process?
Do I need to know the exact OS (cant remember if 5.0.1 or 5.0.2)
Is there a way to get the encrypted data copied and decrypted so I can read it again? (I heard something called adb can be used?)
Things I have tried: Powering down for a while, clearing cache partition, etc. This is the 4th time it has happened in 1.5 years, and I'm tired of it. Warranty/insurance affected by root status so would have to pay for $150 trade-in. Just want my data and ideally move to a new phone.
Do you not have a recovery backup you can restore ? What exactly are you concerned about loosing in terms of data.. are you worried about loosing pictures saved on your phone or say.. text messages ?
@fOmey - I'm not sure if I had a recovery backup. I did have TWRP(?) installed, though. I am worried about losing many pictures and also app data (to do lists, etc.) that aren't synced with a cloud service.

Boot into TWRP and check if you have a backup, if you don't have a backup you can dirty flash your rom and with a bit of luck you'll boot into your OS.
Is there a way to perform a nandroid or similar complete backup without a custom recovery like TWRP (which there is none for Android 11 or the Oneplus 8T right now).
I know I could use DD to dump and restore all the partitions, but I am unsure if this would work for the data partition cause it is encrypted. Cause I think the encryption keys are stored in the trustzone and can't be backuped or restored?
Do anyone know of a solution? Would be nice to have a good working backup to fall back to in case I break something when I start modifying the device more.

Hello Qnorsten,
I´m new to OnePlus devices (using a 8T model) and searched also for a backup method just to be shure that I can restore my data after a soft brick throgh a bad magisk mod.
On OnePlus 6T forum I found the magisk module ´migrator´ which can be used for backup and restore data and system data. I will test it the next days if it works for me.
Do you know more about migrator? https://github.com/VR-25/migrator
Hello,
I've been trying to root my Note 9 using the "N960F_DS_N_Oreo_Root_for_OEM_issue_devices_V5" which I've found online and i believe it is based on what was developed by Dr. Ketan.
While flashing this setup, I selected "Proceed with ROM Flash and Multi tool", "Patch for OEM issue", "Flash Kernel Patch for RMM" and then "Root with Magisk". Once the installation is done and the device is rebooted, the phone no longer boots. It shows the logo Galaxy Note 9 powered by Android then black screen then loop again to Galaxy Note 9 logo and it stays in this loop. I can only break the loop by entering to the Download Mode and loading TWRP and staying there.
I'm suspecting that the "Flash Kernel Patch for RMM" that I've selected is not supported on my Note 9 Model.
Is there a way to revert back this change? or may be install back the default kernel?
Appreciate your help!
Regards,
Elias
As I can see you are proud owner of a softbricked phone.
My recommendation: re-flash phone's Stock ROM to get rid off of all mods you applied to the phone.

Thanks for your help.
I've downloaded this: https://androidfilehost.com/?fid=4349826312261705548
It's around 4.8GB. Is this what you're referring to?
Just to give some background, the phone got an accidental factory reset (which I still don't understand how) and i'm trying to retrieve at least some of the deleted data (mainly pictures/videos). All the recovery tools requested to have the phone rooted in order to do a deep scan. So I started this learning journey myself since no phone repair store was off help.
Would reflashing the phone stock ROM affect my chances of retrieving my data?
Thanks!
The Factory Reset performed erased all your user data: though they are still physically present on device, their entry in Android's MTF got removed. IMO it requires a forensic tool to recover them.
As soon as you re-flash the phone with Stock ROM the disk space utilised by user data again gets wiped ( means a new MFT gets created), so the chance to recover user data previously stored there is NULL.

I was checking this thread on this form: https://4pda.to/forum/index.php?showtopic=915992&st=520
it seems that it's the same problem as mine and he was able to resolve it by flashing the original kernel. Not sure how i can do the same.

With regards to recovering wiped user data: As I can see you didn't get it.

hmmm, what i understood is that if I go and flash the phone with Stock ROM (to make it boot again) I'll lose any chance of getting my data back even with a forensic tool. Is that what you meant?
So I was trying to say that what if I just flash back the original kernel to solve my booting issue, would it also affect the possibility of retrieving the lost data?
Unless I'm confused with the terminologies and flashing kernel is the same as flashing the Stock ROM. I'm quite new to this .
I appreciate your help!
@EN90
As with Android
Kernel is the core part of Android OS and is based on Linux. It is the system which initializes, configures and sets all hardware components for use. It prepares the complete system for functioning. It consits of several sub-systems and services.
Stock ROM is a read only memory chip on the phone's motherboard that contains the Android OS image that boots every time you turn on your phone. A ROM contains full Android OS system and a few system apps that comes pre installed with the device.
Hello, I have been struggling with an issue in my moto e5. I unlocked bootloader & installed custom roms. Then I thought I should go back to the stock rom & I did so. But after booting up, mobile data doesn’t work (No service). Auto rotation doesn’t work. Also it can't detect when I pick up my phone. But in custom roms, there is no issue like this! I flashed stock rom using rescue and smart assistant tool. I also did flash using fastboot commands batch file. But the issue persists.
Next I found that imei is lost in stock rom. So I installed custom rom, backed up "efs" from twrp, installed stock rom & restored the efs. I got my imei numbers back! But no service and auto rotation issue is still there along with other disabled sensors.
What else should I backup and restore? Or what should be my next steps?
One always backs up the whole Stock Andoid before flashing anything. Only blue-eyed people do not.
