Man, if you was in Nougat and return back to MM you have some procedure to make...
You do not read arround? Is a lot of tutorials and guides about that...
Your phone is a mess now...
Before going into the subject, I'll say that I have tried to seach this matter in XDA and Google, but nothing showed up.
Okay, so my matter is that I can't restore my backup of stock rom(8.0) after I flash a 8.1 rom. I've backuped with official TWRP "recovery-3.2.1-2-oreo.img".
My procedures are :
back up stock 8.0(system, data, cache, efs) with official TWRP "recovery-3.2.1-2-oreo.img"
flash oreo rom(with wiping internel, data, system, cache) and boot it fine.
restore my stock backup with same TWRP
boot system
The results are :
Goes past boot logo
Boot animation('android one' with colors sliding) shows up
and... just infinite loop of boot animation.
The ROM I used is RR.
I think the main problem is related with encryption.... Just my thought, tho.
So what I'm asking is :
1. If you face the same problem as me?
2. If you aren't and you restore goes fine, please tell me your procedures including ROM used and TWRP used.
3. Whether it is safe to decrypt stock rom?
Thanks in advance!
You don't need to flash stock ROM again. You have a system image backup(system, data, cache, efs), right? Wipe data , system, cache if you are coming from any other ROM. Then reboot to bootloader. Boot into latest TWRP from Fastboot (don't flash). Then go to restore and restore the system image you had backed up. Don't restore efs if you haven't lost your IMEI.
I've done exactly as ypu told, but it doesn't boot...
Did you manage to restore without problem with your method?
Yes I was able to. No problem here.
What TWRP did you use? Also, what ROM have you flashed?
Used the latest TWRP by MohanCM for Oreo. I did it when I was on Lineage os and wanted to go to stock
@guy_infinity Okay, thanks for your answer! Gonna try out later, once more.
Hmmm.... Still didn't boot up.
I thought I had to do everything from the begining, but flashing stock with save userdata option rescued me.
P.S. does anyone know about the error E: recv error on uevent?
try flashing stock rom using mi flash and after flashing restore normally using latest twrp/deadman's without system image voila everything will be back
@arjunbalan1994 Big thanks for your suggestion! Will try that too later
Hi, did you solve your restore problem? I have the same w/ my Redmi Note 5 and stock Miui backup after flashing RR.
Thanks for your help
I was use 8.1 root and twrp recovery. Yesterday fastboot flash may rom and update 2nd may OTA
Don't understand : May rom is Miui rom?
And did you restore your miui rom 8.0 backup ith twpr after the fastboot flash stock?
Does anyone still have a running P 10 lite? I wiped everything with twrp recovery!!
My phone model is WAS-LX1A. I still have access to recovery. Please help me to get back my phn
Hey folks,
I was trying to do a full backup of the stock rom before flashing a new rom, but I am getting this error:
Unable to locate '/boot' partition for backup calculations.
Does anyone know why TWRP does not list the boot partition?
I am currently running twrp-3.7.0_9-0-prague.img.
I have also tried twrp-3.5.2_9-0-prague.img, but same issue.
Thanks in advance
