i recently backup my grand 2 stock rom via cwm. and flashed twrp recovery to flash aditya v3 rom. but now i aagin flash same cwm version and restoring my backed up rom. but when system respore completed, data restoring start. its show error while restoring data. that's why i flash cm12.1 by mukulsani and backup this rom via twrp to check. but in twrp same problem again. when system restore completed, data restoring its say error.
what is the problem? help me. plz
TWRP backup doesn't give me the option to backup /data and gives an error saying unable to mount /data, mounted without encryption
Running stock b160, on vns-l21, rooted systemlessly with magiskSU, running systemless xposed.
deleted ....... wrong, i saw that you have meticulus twrp, that was my suggestion
i also have this problem and not only can i not do a backup of the /data (it doesn't show up in the first place) but i also cannot flash a different ROM.
i have a big problem: I am on stock rom, used twrp 59 to flash supersu and to do my first nandroid backup some days before. All was working fine.
Then i noticed, that there is an system update Oxygen OS 4.5.5. I downloaded it in OTA updater and sytem booted to twrp. I know, that i cannot flash OTA Updates, but i want to try what happens. It happens nothing and i booted back to system. Then i downloaded the 4.5.5 full rom and want to flash it via recovery. First i want to make a nandroid backup and then the s*** happend: I could not see my TWRP Backup, which i make the days before, i could not flash the rom or any zip, i cannot wipe dalvik/cache (mount issue), i cannot find my download folder.... i booted back to system and downloaded latest stable TWRP (62), i flashed it via fastboot... same results.... then i want to go back to system and system does not boot anymore... that is the biggest problem at all... it stucks on the two little white rings which circle around the red spot on black screen.... in this board i read something about decryption... Ok... i type my passwort for decryption in TWRP and it seems, that i can get to all my files on my sd card in twrp.... but there was a issue "Faild to mount cache!!"...
And there is still the issue when i want to wipe cache/dalvik or to flash the fuff zip (not able to mount - invalied argument)... and system does not boot up anymore.... what can i do????
i have no Idea.... thanks for your help!!!!
if you can flash stock recovery then you should be able to boot to recovery [stock] and fix it from there.
Use the twrp before. That Mount issue should be gone

Hi everybody, since i restore my nandroid backup (to revert xxx rom to stock), it is impossible to mount system partition... and recovery twrp 3.1.1.1 say "can't mount system (structure needs to be clean..). How to solve this problem? Please i need help
edit: problem solved with an internal install of OOS... and after must reflash twrp and root
@brunsman6229 Could you tell me how exactly you solved the issue? Getting the same error and would like to know how to fix it!

Hey, can you plss guide me through this. What is internal installation?
Will all of my data be wiped??
I fixed it by dirty flashing No limits rom. If you have a nandroid backup in hand, wipe everything except internal storage, dirty flash the rom then restore the nandroid backup.
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?
