Hi to everybody, just unlocked the phone and I am doing the first Twrp backup. Is it normal that the size of the backup is more than 26gb?
See the attach!

A little while ago I installed a corrupted boot animation that caused a boot loop. Then I restored the CWM backup and it was able to restore the system but not the data.
Now since I am planning to flash a custom ROM I deleted the old nandroid backup and went on to do a new backup. But CWM was able to back up only the system and not the data saying that data folder is missing though I checked using ES and data folder is there. I had made a backup before and this problem wasn't there.
Any solutions or will re flashing the recovery help it?
I am using CWM touch by Phil.
you are using the latest version of Philz Touch recovery?
I was the same in an older version, or if you try to switch to another as TWRP recovery by TeamMex (the last version before)
Hello Guys,
Today a friend come to me and gave me his phone to put a custom rom on it.
He said that he unlocked the bootloader, flashed TWRP recovery and has a twrp backup of the stock rom.
I have done a factory reset and formated system. So I flashed the custom rom but twrp told me that i'm having the wrong device. I wanted to restore the twrp backup but there wasn't a backup. Now I have a non starting phone with no backup. I have tried everything but I didn't start.
PROBLEM SOLVED:
I downloaded a TWRP Backup which was made for my HBOOT version and put it on my usb stick and connected it via usb otg. Restored Backup with TWRP and the thing was done.
Tried to clean flash unlocked and rooted OP6 from OOS 9.05 to 10.3 and got stuck in "bootloader unlocked" (only later learned that I should have gone via 9.09 to 10). Tried to restore Nandroid, but this did not work either and even lost the recovery.
Now I can go to recovery only via "fastboot boot" and only using twrp-3.3.1-18-enchilada-Q-mauronofrio.img (none of the other recoveries I tried will boot). I tried to restore the backup (with and without reflashing twrp-3.3.1-18-Q zip afterwards) but never manage to boot back to system (maybe because the restore is 9.05 and the above TWRP is OOS10; it starts up with the ASOP10 log ?)
Is there a way to restore 9.05 with the nandroid without wiping the user data ?
(like flashing the nandroid twice on slot A and B and flashing the correct TWRP and/or Magisk afterwards) ?

Problem solved!
I followed this post https://forum.xda-developers.com/showpost.php?p=78915106&postcount=2
(reflash same ROM and Magisk versions as those originally installed, then restore nandroid backup).
3 things to note which were not obvious to me:
- Unzipp ALL files into one single folder (same ROMs have zips within zips)
- use the "flash-all-partitions-fastboot.bat" file,
- answer NO to the first question "Wipe all data (recommended)". If not, the internal data (data/media) will be wiped as well, including your nandroid backup and other info (music, photo..). If you have to wipe, make sure the backup is on the PC
Hi there, Thaught, I was on the save side for 2 years, having my TWRP, made a backup after every change on the 12+, now I had to recover it...
Steady installed TWRP 3.3.1.0 on 1.68.401.6 does a restore without errors, restart ends with bootloop.
So I flashed new with 1.53.401.5, tried to fastboot boot twrp.3.2.3.3 and restore my backup -> bootloop
Flashed 1.53.401.5 again, made a backup of that fresh system with booted TWRP, to test that restore, brings the same bootloop.
Have to say, the twrp versions are the right ones for the used SW versions. Decryption is working.
Where is the blind spot in my brain??
Please delete my ask here, I'll try my luck in TWRP thread. Still my problem.
I had to send in my Galaxy S9+ (Android 9) for repair and backed to all partitions with TWRP. Then I factory reset it. After I got my repaired phone back I thought now it's time to update Android. I flashed to Android 10 with a new bootloader. Then I wanted to get my apps and data back from the backup from Android 9. I wanted to restore my full TWRP Android 9 backup. I could restore the backup, but the phone does not boot up.
Meanwhile I read that once updated a new bootloader one can't go back to a lower Android version. Can anyone tell me why? When I back up my PC (linux) partitions with dd and restore them, everything is as at the time the backup was done. Where is the difference between phone and PC? This is just for my understanding.
The main questions is what I can do to recover my TWRP backup done in Android 9:
Is there any way to recover my data from my backup images?
Do I have to buy another S9+ with Android 8 or 9 to be able to recover my backup and access my data?
Any backup created by TWRP is a TAR archive you can extract by Windows / Linux command line.
You can't rollback after updating the bootloader, because flashing the bootloader to a lower version isn't done in the usual ways.
Think of it as PC's BIOS, they both have similar functions. Can you update a BIOS normally?
So to answer your questions:
You can try a different version of TWRP, specifically v3.5.0+ as it supports dynamic/logical partitions of android 10.
You can also extract any backup done by TWRP.
Finally, you can always just flash a custom ROM and restore your backup.
Thanks a lot for your answers so far.
When I did the backup I chose all partitions to be backed up. When in my situation I cannot restore all partitions to not to soft-brick the phone, can you please tell me, which partitions of my Android 9 backup I have to choose in TWRP to restore in my Android 10 system?
