Nandroid Restore gone wrong

Hi,
I have tested the liquidremix rom which is great, but I still wanted to go back to my stock OSS
So I started TWRP, hit restore, everything seem to work fine, but when I reboot the system I'm stuck at the boot animation.
When I reboot the device to TWRP and check the file manager or my backup folder there are only cryptic and weird letters...
How do I restore my backup properly ?

Try to go back to TWRP 3.2.1.0 i think that that works

everything is gone, you will have to restore with the brick tool, happened to me last week and still not sure why, apparently backing up with TWRP you only need to ticket DATA and that's it.

You need to do two things whenever you restore with TWRP. First is factory reset in TWRP before the restore (that will wipe data). Second is restore system, boot, and data ONLY.
The weird file names and cryptic letters is from the encryption from the old rom. I strongly recommend that you invest in an OTG flash drive so you can store TWRP backups on it. Then you can properly wipe the phone. On the plus side this has happened to me before and I never needed anything special like the unbrick tool to get my TWRP backup up and running smoothly.

and there is a better twrp than twrp. The official is by Dees Troy and the un-official one by Joe Moss Jr. is here. https://forum.xda-developers.com/oneplus-6/development/recovery-twrp-3-2-2-0-touch-recovery-t3813317
Joe's big improvement is a usable 'mtp', ie. access that thumb drive.
Also puts the vibration back in to the key press.

First if you r seeing weired letters in twrp like xdjdhdhdhd folders. Then go to fastboot mode flash newest twrp. Img then ij recovery first flash your liquid remix furst, then flash twrp installer zip niw reboot to recovery.
Now factory reset your phone.
Now if you have oos backup. Then restore everything except system.
And then restore system alone at last now reboot it will work.

your gonna need the flashable oos 5.1x which is one here
https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244
fastboot to twrp
abd push the stock.zip to the phone <-assuming you know this.
and flash it from twrp.
reboot
fastboot twrp again and flash twrp.

this is where decryption comes in handy

Restoring backups with twrp will fail almost all the time. I've yet to do a successful restore and I've tried every method. You're gonna have to flash back to stock OOS and start over.
If anyone has successfully restored more than one backup then I would start a new thread with the exact method you used.

That worked.
I still wonder why not to restore system.
If I take a nandroid backup should one backup
system or system image, data or data image ?

I was trying a new rom the Resurection Remix V6.2.0 Android 8.1.0. i wanted to go back to my TWRP Backup of OOS 5.11 . I wiped data/cache/System . Tried to restore rom . it restored successfully but i didnt do wipe data thing. when i tried to reboot twrp blu, the recovery was lost. then i had to fastboot boot reovery. and lot of wierd folders were created on my phone internal memory. All data lost.
i had to flash the full 5.11 stock zip via twrp. tried to reboot again lost in bootloop. Switched back to stock recovery and make a factory reset then it booted.
switched off the phone back to Blu spark TWRP. again wipe data cache and system. Then restore the TWRP Backup previously double saved on a usb drive. This Time it restored successfully and booted as well fine.
i think i should have made a factory reset or format data before restoring from A Lineage OS Rom OS to OOS TWRP Backup
thats what made the whole internal drive mess and to be formatted as well
My Question is it only important to format data and then restore twrp or also backup and make restore of system.img of OOS backup as well

If I completely wipe phone can I restore TWRP Back up

If I use the tool to reset OP6 to factory and root it again. Then update to latest could i restore old twrp backup from same phone?

Yes you can if you stored that twrp backup in your PC.

I think that you can't. I tried few times and never got it right. There are always some errors. Maybe something changed in the meantime tho...

Just backup data in TWRP. Install everything else normally. Full ROM zip, TWRP zip, reboot recovery, flash magisk, boot. Data will be in tact regardless, unless you wipe it or factory reset.

Need Help to restore backup with TWRP

Can anybody help?
My HTC U11 still run on Nougat.
Yesterday I want to update with the newer version of Nougat (Not Oreo)
I already make a data backup with TWRP, big backup 22Gb.
Then I update the new stock Rom from PC, it had no problem.
Go to download mode, and then install TWRP again with ADB from PC.
Go to TWRP Recovery, it still works.
The last thing I do is to try to restore the 22Gb data back to my phone.
And it always get error on 9% with "extractTarFork() process ended with ERROR: 255"
I already change with difference TWRP from 3.1.1.0 to 3.2.3.0, still the same.
Restore to previous version of Nougat with TWRP (system, system image, boot image, recovery). Try to restore backup data again with no luck.
Try to check MD5 with the backup data, and it said matched, no corrupt.
Already try searching in the web, but with no solution too.
Do anyone ever have the same problem and solved it?

Did u try a format in twrp before installing the backup? Just thought

No, not format anything. Afraid did something would make the phone brick.

I have 2 backup. One is for system and one is data. I can restore system feom TWRP recovery, but can't restore data

After restore system,reboot to twrp and restore data

I had this problem and it took me two days to resolve it. I had a good backup and I know it was good because I had used it several times and it worked. But then after doing some system installs I got the error 255 when I tried to restore it. I tried several things to fix it and nothing worked and I really did not want to lose my backup. What did work for me was to use TWRP wipe function to FORMAT the phone. Wiping or factory reset did not work. I lost the contents of my internal SD card but I was able to transfer most to my external SD card. You could also connect the phone with a cable to a computer and use the pull command in ADB to backup the contents f the internal SD card. Given the choice between losing the SD card and the data files I come to lose some of the SD card. Anyway, a FORMAT worked when nothing else did. I read that this error is caused by a lack of space. When I checked the log it seemed that the restore was failing with a particular file which misled me to thinking I had to remove the corrupt file, but since after the format I was able to restore without any problem, it would seem that there was no corrupt data. Hope this helps someone.

after whiping data, phone is stuck and twrp does nothing

Hey guys,
I have a oneplus 6red rooted with magisk and twrp running oreo 5.1.11, today I decided to enter twrp and reset my phone by whiping dalvic, cache and data.
After reboot, phone screen is totall dark but the light indicator was flashing constantly, entering twrp is no succes, twrp screen is stuck like more then 10 mins. I believe that I cant enter twrp to do something about it. I have downloaded the stock 5.1.11 which is an oreo version
Did I do really something wrong ? if yes or no please let me know how to fix this.

Try bluespark TWRP and flash your OOS zip again and report back. Maybe a magisk flash will help too.

thnx, I entered into fastboot mode, then from my pc I when into the fastboot folder to open cmd and boot twrp from there on my device, from there I followed a tutorial how to adb sideload and flash a rom from your pc. Now its working
But I dont understand why a simpel factory whipe through twrp caused all of this, I only wiped dalvic, cache and data.

This may be a side effect of A/B partitioning and no longer having a recovery partition. Remember TWRP is a part of the boot partition now

Use a fastboot rom. That will wipe EVERYTHING - and guarantee that you have a usable phone afterwards

You probably wiped system that's why you had nothing to boot into

i am almost sure that it was data and dalvic cahce and not system, that is what i also explained in my first post.
But how are you sure that it was system wipe ? did you factory reset your op6 multiple times without issue through twrp ?
phone is fixed btw

Its the easy answer, say that you wiped system or such.
If you wiped Data with Magisk installed, without flashing the stock kernel, you won't be able to boot, since Magisk stores stuff necessary to boot on Data.
Usually, people is stuck on a infinite bucle on TWRP after this, you couldn't even enter TWRP? that's new. The issue you're telling sounds like you changed slot in TWRP somehow to an unused one or something like that, never heard of that.

Yeah I have wiped data in twrp with no issues. TBH it just sounds like there was no system to boot into. Wiping data is just that and shouldn't make the phone unbootable. Also you fixed the issue by flashing OOS which makes me believe this also. If you want to factory reset your phone the best way is to do it through settings.

Always booting to TWRP

Hi,
I am using polaris with LineageOS 16. Today I installed newsest vendor firmware and newest LineageOS. Before that, I used TWRP to backup all partitions.
Because of an issue with playing MP4 videos I wanted to go back. So I used TWRP to restore the recent backup with all partitions.
Now my phone does not boot anymore. Every time I power on my phone it boots to TWRP.
Any ideas? Thanks for every help.

Thank you. Do I have to wipe anything?
Or is it enough to only exec
Code:
adb sideload filename.zip

Thanks. Format, Wipe, Sideload and restore data partition worked for me. You made my day
