[Help] Stuck in fast boot- boot loader after restoring twrp backup? - OnePlus 6T Questions & Answers

[Solved (look at bottom of post)]
so, hopfully this is in the right place.
Following the procedure I've done on my nexus 6p many times over; I created a TWRP backup on my 6t then tried restoring the backup I made with twrp and when it finished I pressed reboot to system. The device then only booted into twrp. I saw it was on the "a" partition and I knew I was previously on the b partition so I manually switch partitions and now I'm stuck in fastboot boatloader I have tried flashing a temp twrp.img but im getting an error "FAILED (remote: 'Failed to load/authenticate boot image: Load Error')" in fastboot
After that I switched active partition in fast boot and got into twrp but my data appears to be encrypted and after restoring sys,data,efs,vendor (skipping boot as it holds the recovery now) I only have fast boot in both a/b partitions. I'm going to try to fast boot twerp then install twerp permanently and see if i can get a wotking twrp if not then ill have to get a factory image to get back to stock but was hoping to get some data off but whatever..
I'm kind of new to this a/b partition setup. any help is appreciated.
Edit: for future reference All I was doing was trying to restore a backup? how do I restore a backup on an a/b partition system? As far as I know I did it right...
1) remove lockscreen pin ect..
2) backup boot,sys,ven,data
When restoring
1) mount partitions
2) select restore backup and restore all .....
What am I missing?

twrp for 6t is borked when it comes to backing up/ restoring...
The version in question: twrp-installer-fajita-3.2.3-1.zip
I restored my 6t to stock with msmdownloadtool and reinstalled twrp then made a test backup. After restoring it I was left in a twrp bootloap and encrypted data partition.

I don't think you should ever need to manually switch slots.
If you are on slot A, and flash an update, it will install to slot B. When you restart your phone, it will automatically switch to B for you.
Also, you shouldn't be flashing the TWRP.img, but booting it instead.
You could try starting fresh with the msmdownloadtool which is found in these forums.

I'm currently stuck in TWRP with encrypted data after restoring a backup. I didn't know you couldn't restore backups on this phones. That sucks. I guess I'm going to have to start over now. That really really sucks.

Yup, I felt the same.. it's a huge bummer especially when you get it all set up and perfect. Use msm to fix it if you can't use twrp. Hopefully twrp gets fixed soon (I'm really surprised I can't find more people who have noticed this or even twrp team talking about it) for now Im waiting for proof it works on the op6t. I even tried to use Chainfire's flashfire to make a backup and.. no it doesn't work.

Use Msm download tool:
https://www.google.com/amp/s/forum....-msmdownloadtool-v4-0-oos-9-0-5-t3867448/amp/
I think that's the right post but make sure it matches your device. I used msmdownloadtool around 6 time just testing twrp and only had one hiccup where Msm wasn't detecting my one plus 6t but I eventually got it working.

use the other twrp unofficial but problem you had with would be fixed with big file system fat32 can't do it right

Could you post a link to it and are you sure? I used the unofficial version so which one are you talking about? I'd really not like to have to re-setup my daily driver from scratch.

https://forum.xda-developers.com/on...overy-unofficial-twrp-touch-recovery-t3861482 your using early version of twrp the black one is made by same guy download unofficial twrp.zip not twrp.img reboot recovery flash twrp.zip then magisk it may work if not then format data (erases phone) then twrp,magisk reboot recovery to see if it stuck I flash magisk again when it starts up go to magisk thread get the manager 18.1 don't insall it

Which one? I've tried the 3.2.3.28 last and restoring didn't work. Should I try the most recent installer in the list? And can you confirm that backup&restoring works on the one plus 6t? Also is there anyway to backup my phone without twrp before I try this? I'd really would not like to have to use msm again?

sorry that didn't help format data then flash twrp then magisk should boot without msm
---------- Post added at 01:06 PM ---------- Previous post was at 12:52 PM ----------
i had to use extfat format on htc 8gb backup to get it to work maybe devs will fix that

Has there been an improvement on twrp for the 6t yet? Just curious if I can rely on a backup is there any updates?

TWRP hangs on booting to recovery

Ok, I messed up somewhere.
I had Nexus 6p running on MM, rooted along with xposed.
I had downloaded the beta OTA but not installed it.
I used flashfire to flash the old 6p image (the same one that was installed) and flashed system, boot, recovery, cache and vendor.
Then I updated using the downloaded OTA to N. When I did that , the phone showed me the corruption message and booted to recovery. My phone was being detected by adb in normal mode, but not by fastboot in the bootloader, somehow I was able to get it to detect and installed my older TWRP 2.8.7.2 recovery, which was able to decrypt data. After that, I sideloaded Android N via TWRP and even flashed TWRP 3.0.0.1, but it hangs whenever I try to boot to recovery, never been able to go past the TWRP bootlogo. Is there anyway I can get TWRP to work again without wiping data/userdata? I'm guessing it's all happening because of encrypted data.

Is there a reason you're messing around with Flashfire and sideloading instead of doing it the proper way via fastboot? I'd suggest taking that route now. I have instructions on flashing factory images in my guide:

I just had a phone next to me at that time, so I thought I'd be able to do it without a pc. Now I know it wasn't a good idea
So you suggest I fastboot flash everything like you've mentioned in the guide without formatting userdata and data? Also, should I flash twrp at that time as well? Do I need the modified boot mentioned in http://forum.xda-developers.com/nexus-6p/general/stock-modified-boot-img-regular-root-t3306684

Yes, flash everything except userdata. Personally, I'd be wiping data with TWRP first though, just to make sure there's no lingering data causing problems moving forward. You can use Titanium to make a backup of your user apps first, and then restore them afterwards. No you don't need the modified boot.img.
In response to one of your initial statements though, I don't think TWRP is hanging due to not being able to decrypt. The 3.0.0-1 build has been patched so that it can decrypt.

Instead of relying on the recovery partition on the phone, you can live-boot TWRP with fastboot. This will boot into TWRP using the TWRP image on your PC, via the fastboot connection. The command is as follows:
Code:
fastboot boot twrp-3.0.0-1-angler.img
Then you can flash SuperSU, make your backup with Titanium, and continue on.

sorry to bug you often, but i had no luck with live booting 3.0.0-1. I tried with 2.8.7.2 and it booted, asked to decrypt data. tried my pin/pattern as well as default_password but no luck.
the log says:
E:Unable to decrypt with default password, you may need to perform a format data.
E:unable to mount storage
E:unable to mount settings storage during GUI startup.

That's odd, I can't think of why 3.0.0-1 wouldn't boot, but 2.8.7.2 definitely won't work as it obviously can't decrypt. You might not be able to backup.
Enabling 'require pattern at startup' allowed 3.0.0-1 to boot but this time it was stuck at decrypting.

is it possible to sideload supersu somehow?

Maybe, you could try adb sideload in TWRP, but SuperSU needs to access the data partition which TWRP can't decrypt.
I tried it and it got to
**Boot image patcher**
patching sepolicy.
Failure, aborting.
i seem to have the same issues too. unable to access recovery and lost root. phone cant be detected in fastboot.
supersu 2.69 to the rescue. chainfire auto root worked with encrypted data
1)So, now the best way forward is to backup via Titanium and format data?
2) will fastboot erase data erase userdata as well?
3) after the format, will data remain decrypted or do I need to do something else?

Great news
1. Yes.
2. I don't think such a command exists. You'd need to use the "fastboot format userdata" command instead if you want to decrypt anyway. Just remember to backup all your data first.
3. You'd need to flash a custom kernel today doesn't force encryption. Otherwise your data well will automatically encrypt on the first boot after formatting.

Help needed! Firmeware CAN-L11 EU Version

Hello,
i need help. I messed up my phone while trying to repair my only read mode system partition after boot.
Current state:
Phone CAN-L11 with EU Firmeware and working TWRP Recovery.
I did a full wipe, but have no data partition to restore, because this couldn´t be saved with twrp while i made my first nand backups during no read access to data partition.
My phone always shows 2 times the huawei logo and then boot in erecovery from huawei where i tried to restore, but it shows always "fail to get data" (wifi works).
When i restore all partitions backups that i own via twrp i miss the data partition (is the cause why it wont boot - isn´t it?)
Now i searched for any img that i can use to get my phone working again - anyone has a tip what img i could use (i have a huawei update extractor) - through twrp or fastboot.
Could anyone help me with a twrp backup or a img file of data partition - or has another tip how to get my phone working again?
Thanks for tips!

I think that you need a system.img, so you can flash. This system imagem would write everything you need, so you can boot normally.
Have you tried to dowload @bluesmoothie backup from dropbox from the Root and Recovery post?

Here the full Backup for the CAN-L11:
https://drive.google.com/open?id=0B134drJ4-Ed0R3VSY3A5NGpjVWc
Format /data, reboot recovery and than restore from backup. After the restore is complete make a wipe.
I restored my system from twrp (original first save). But that did not help.
After that i loaded the can-L11c432 update.zip from huawei and extracted with others the system.img - that also did not help to boot.
Tomorrow i flashed the orignal recovery.img from c432 but i did not find an update.zip wich works to manually flash in stock recovery.
@Vinnom the link you shared leads to twrp.img (no system.img).
@-=MoRpH=- thanks, i will try and report back. Is this anyway a chinese version in there? I think i have the same struggle you had days back. Is your phone completely working again?

@merlin21 yes it sounds like my problem after I tried to flash the emui5 beta.
My phone is fully working again with the backup I posted.
This is not the Chinese version, if nothing works, you can try the caz ROM. But there are massive problems with the gapps, they are not included in the rom.

i just flashed the twrp.img with fastboot from xelfmade v22.12. and then rebooted twrp.
Then formated data and confirmed with yes - rebooted recovery and tried to restore your twrp. It did not restore and aborted instantly with the error message
during restoreing cust...
extractTarFork() proecess ended with ERROR: 255
what could that be?
IT WORKS! Thanks @murph... I had to use the cust from my backup, but with your data partition it successfully booted again. Locking forward if i now have still the problem with read only system partition. I am away setting up phone again (and of course rooting, modifying etc.. but FIRST do a full backup after basic setup and safe in PC !!!)
Thanks!
P.S. how did you manage to back up data partition in recovery? I thought this wouldn't be possible?! What is the cost for having this full working twrp?
PPS. Somehow knock on screen for screenshot does not work - could be, that i have to log in with huawei id... does it work for you morp?

That only work if the is not rooted... Idk whats up with that, but for now i use the quicksetting screenshot function.
Somehow it worked with my rooted device before. Must be the decrypted data partition?
With the recovery of your backup I could not access data or change memory from data to sd. What version do you use?
I flashed xelfmades v22 and now have rw access and could backup all partitions and restore. Root and xposed modules everything works, just the knock on screen to capture don't...

May I ask how?
I'm kinda stuck personnaly. I have tried both Nand backups but no cigar. Still can't boot. I had the Data issue which I managed to get rid of.
I still end up with a ExtTarFork 255 kind of error. I tried to change the files attributes via adb shell, but it failed so I've got an OS-Less phone...
Any help would be greatly appreciated.

I copied the backup, which is linked somewhere in this thread, to my sdcard and restored it on my Nova using twrp. The extractfork issue showed up while restoring '/cust' so i disselected cust in the restoring menu. After that the restoring worked and my nova was able to boot.
Hope this is any help to you.

That didn't do the trick for a while, or I might have forgotten a step, but deselecting CUST did the trick.
Thanks for the tip!
Although, maybe flashing the Cust partition I found in one of the two upgrade zips via fastboot might have helped? I dunno...
But in short, for those who haven't followed through, here's what I did, but I'm not sure this is why it worked:
1. Bricked my device : be sad;
2. DLed all the posted Nandroid backup on this thread and others;
3. With fastboot, reflashed TWRP from Xelfmade using "fastboot flash recovery twrp.img";
4. Flashed the CUST.img I found in the UPDATE.APP of the update_data_full_CAN-L11_hw_eu.zip; or maybe the other, only one of the two seem to have it; I extracted it using Huawei Firmware Extractor; using "fastboot flash cust cust.img";
5. Created a "fake" backup to create the right folder structure on my SD (TWRP Couldn't see the backups) and put the Nandroid Backups I DLed earlier in it;
6. Reboot in TWRP and Restore all partitions except CUST;
7. Reboot, sweat, wait, cry, roll on the floor in fear, heard the huawei startup sound, cried as if it was my first born child;
8. Setup the fone and profit; then enjoy Nova goodness;
92.324. and probably most important, TWRP BAAAACKUUUUP!!!!!
All done!
Thanks for your help my phone is saved with your method!!!

Can any help, please?

Frankly, I don't know. I had not modified the partitions prior to bricking my phone, so I think the partitioning was OK. However, I think one of the TWRP availble in this forum can format Data partition properly, which would utlimately allow you to select which File Format you want. I haven't tried it myself, and I haven't been able to do much with TWRP since I flashed Lineage unfortunately. Most of my Mods were just upgrading and I had to ADB Sideload pretty much everything since I flashed Lineage...
Sorry I couldn't be more helpful than that!

[HELP!] TWRP createTarFork() error 255 when backing up data

I have installed FreedomOS on my OnePlus 5. I'm not sure if this is related to FreedomOS, but when I try to make a backup in TWRP with data, system, and boot, it has an error with createTarFork() shortly after it gets to backing up data. It also says 'read only filesystem' when I try to open Terminal from Advanced and run 'cd /data/media/0/TWRP/BACKUPS/bad7d639 && rm -rf backup-name'. What can I do to fix this and why is this happening?
EDIT: I have 32GB storage left
I had error 255 when restoring the data partition on my elephone p9000, for me it was because it was a bad data write and it was corrupt.

Hi guy, i had the problem, try to flash blue spark recovery and retry restore, if rom bootloops, try to dirty flash your rom
I just wiped and reinstalled OxygenOS http://downloads.oneplus.net/oneplus-5/oneplus_5_oxygenos_4.5.10/. Once I reconfigure all my settings, files, etc, I'm going to see if it works.

I can't restore; I deleted all my backups in an attempt to free up space.
I think I found the solution!
1. Go to Wipe in TWRP, swipe to factory reset
2. Download:
OnePlus Recovery: http://oxygenos.oneplus.net.s3.amazonaws.com/OP5_recovery.img
OxygenOS: http://oxygenos.oneplus.net.s3.amaz...3_OTA_015_all_1708252353_e6d7756780064352.zip
3. Rename recovery image as recovery.img, boot phone into fastboot, plug into computer, run these commands on the computer:
fastboot devices
fastboot flash recovery recovery.img
fastboot boot recovery.img
4. Open recovery on phone
5. Select Forgot Password, will wipe all leftover files in SD Card.
6. Boot back into recovery, select reload, select Install over ADB or Install Over USB or something similar and plug phone into computer.
7. Run 'adb sideload oxygen-os-filename' without quotes on computer.
8. Let it install OxygenOS, it may appear to be frozen at some points; it probobaly isn't, so don't shut it off or unplus USB.
9. Download Bluspark TWRP: https://forum.xda-developers.com/devdb/project/dl/?id=26601&task=get
9. Reboot into fastboot, plug into computer and run these commands on the computer:
fastboot devices
fastboot flash recovery bluspark-twrp-filename-location.img
fastboot boot bluspark-twrp-filename-location.img
10. Success (hopefully)
Oh. Wait. Now it has the same error when I try to make a backup. (I feel like it might be from installing https://forum.xda-developers.com/android/software-hacking/kali-nethunter-magisk-t3676681, but they say it's unrelated). Doors anyone know why this is happening again?
the solution to this was to boot to your previous rom that u have made nandroid backup with and then setting up the same password/pin in settings > security. When you then boot into twrp it will ask you for the pin/password to decrypt your data partition and then you can flash the nandroid backup(you have to have the same password there). here it is obvious that you are trying to flash data partition that uses different encryption password (in case of stock rom there is non) and this obviously wont happen.
maybe another solution would be to connect externally usb and unmounting data partition and then restoring from usb...
I'm having the exact same issue, but trying to create a Nandroid, not restoring one. Happened on Codeworkx TWRP 20180414. I always remove my passwords, fingerprint, pattern, and face data before I backup, update, etc. since I'm encrypted to avoid issues, and it still happened. I flashed the latest blu_spark TWRP and got the exact same error in the same spot in the data partition backup.
Never had an issue like this before. I even tried saving the data partition separately and still got the same error. Very strange indeed.
All other partitions backup without issue.
I'm on xXx v10.5 w/ ElementalX v3.04, Encrypted
If anyone has any insight, it would be greatly appreciated.
Thanks much!

For me flashing normal oxygenos with magisk 16 and formatting data and trying to make it boot with the new flash and then rebooting into recovery and restoring made it work. I guess it has to do with the right filesystem having to be made first.
hi guys,
i've read all the thread in XDA related to ERROR 255, can't find anything to solve my problem trying to backup on TWRP ending with this error 255.?
I'm not using any parallel apps, not using Apps Locker, don't have any folder 999 (searched using Root Browser).
I've tried deleting all fingerprint, face unlock and screenlock as well.
No joy.
I'm using latest TWRP 3.2.2-1, OOS 5.1.7, Rooted.
Appreciate any help or sharing experience.

OnePlus 6T Bootloop Help!

So I was using a certain root app and it told me to enable Magisk Core mode and reboot. I did that, and my phone was in a bootloop. So I wen't to TWRP and flashed stock ROM zip. Rebooted and it was still bootlooping.
So I took a TWRP Backup of all partitions, and then wiped system fully and flashed stock ROM. Still bootlooping. So I did a factory reset and wiped system as well, keeping internal storage. Then I flashed stock ROM zip and rebooted - it fixed it, but was factory reset. So I went back into TWRP and restored the data partition. Unfortunately, I got the TarFork Error 255 when restoring. I saw on google that you need to setup Android first to restore. Rebooted to go into Android but it took me to TWRP, and this time didn't ask for decryption password. I went to internal storage and everything was encrypted. I don't remember exactly what I did next but now I'm in fastboot with no TWRP recovery, and when I do fastboot boot twrp.img I get this error: "FAILED (remote: 'Failed to load/authenticate boot image: Load Error')"
Can anyone help me recovery from this and possibly get my internal storage back, or at least installed apps. I can provide TWRP restore log as well: https://del.dog/ivugupemeq

Have you tried the MSM Download Tool to restore the device yet? I'm leaning towards that honestly.

(Double post, ignore this)
Got it fixed by flashing full stock ROM in fastboot without wiping, so userdata was recovered, and then restored app data from the TWRP nandroid backup in Titanium backup

Damn don't even have this phone anymore lol
I think I used the fastboot ROMs from an xda post but when it asks you to wipe or not I clicked no, and then I booted to Android and apps data can be restored from a nandroid backup in titanium backup, just search to find that feature, instead of restoring the data backup in twrp

TWRP can't stay, even flashed by installer

Hi guys,
I'm not newbie with flashing but this one I don't understand.
Probably I've done some mistakes with flashing/install/uninstall of roms/magisk/twrp.
Now I'm stuck with TWRP and can't boot into system because of something.
Every time I run TWRP and try to install all my files are encrypted, no matter I install TWRP by .img or .zip. Only working TWRP with decryption is temporary one, by "fastboot boot twrp-3.3.1-6-fajita.img" command. But when I flash it by regular .img file by this tut (https://forum.xda-developers.com/on...overy-unofficial-twrp-touch-recovery-t3861482), after reboot it's back like 3.3.1-6-fajita version, BUT without decryption skills.
I thing I done some mistakes with uninstalling magisk ect. but I think it doesn't matter.
I tried to uninstall magisk by Magisk-uninstaller-20190204.zip on both slots, I tried install all again in regular way (install temp TWRP through fastboot command, install TWRP through this temp TWRP, install full newest OTA .zip, install TWRP again (I know I shouldn't but I tried both combinations - .zip and .img) and install Magisk and at least system reboot. But when I rebooted between OTA and Magisk (like guide tells) TWRP can't decrypt files. No matter what I've done nothing helped.
What can I do that I have not done yet? Of course, all is about I don't want format my data and re-install all from the scratch...
So... tell me, is possible to make TWRP great again?
Is everything only showing as encrypted when you try to restore a backup? I've been booting the img via fastboot then flashing the zip as it seems you have and it's been working fine as far as it staying installed and not showing all my files as scrambled, I also made the mistake of using Magisk uninstaller at one point, that didn't end well. Seems these A/B phones are temperamental as hell. I read somewhere else that doing backups to USB storage my be more reliable for a backup restoration, not sure if that would effect the encryption issues or not but I may have some time to test that tonight.
I've done that too - not helped. I restored my full nandroid backup by fastboot temp recovery (as I wrote, only this one can decrypt my files) but I've got "You device is corrupt"... and of course TWRP can't decrypt my files.
