Urgent help needed for TWRP encryption - OnePlus 6 Questions & Answers

Hello,
My problem is that I can not access my SD card data because TWRP does not ask me for encryption password. I can see the files but they are all gibberish
How did I end up here?
I was using RR 7.0.2. and doing random magisk module testing and suddenly everything started to misbehave. I panicked and ran Nandroid backup but restoring failed to tar fork something. Then I decided to factory reset and flash original Resurrection Remix rom which I was using and bluespark TWRP which I was using before. I tested TWRP installation by rebooting to recovery.
Booting went well but TWRP never asks encryption password/pattern, which causes sd card data to be encrypted. Is there way to get sd card data decrypted or is it all lost?

You lost your encription keys Im afraid, all data is lost, next time decrypt before flashing any custom ROMs for your own data sake.

wiped, bricked tf300 now installing c/roms but still booting to twrp?

hello, last week i bricked my tf300, this is what happened...
i installed the energy rom along with the 4.2.1 bootloader, i was already using twrp 2.4.3.0 and it seemed to work fine for a while but then i had problems with a double screen after trying a different rom (cant remember which) anyway i tried the usual resets and wipes to to fix it but no joy. I then used the wipe data in bootloader thinking a full clean wipe would sort it but it just booted straight into twrp.
in twrp nothing will mount apart from system, ive used fastboot to flash various stock blobs, proper twrp img etc but even tho fastboot said everything flashed ok, i still boot into the old twrp which wont mount anything apart from system.
i then got an old 8 gig sd card and put stock roms and energy rom on root of the sd card , in twrp i mounted system but cant mount cache, data or sd card but strangely, i was able to copy the above roms from the sd card and move them to the mounted system partition which i was then able to install the energy rom with aroma installer , happy days i thought until after installation it rebooted straight to twrp again asking for password?
when i try to install stock roms by the above method it fails because cache isnt mounted. i think the twrp is corrupted, how do i fix this?
could someone with the know how tell me what im doing wrong,? should i full wipe again? should i wipe the twrp and how do i do this?
i am sort of a newb to this and any advice would be great

[Q] TWRP cannot read my sdcard (encrypted?)

So, my previous post was a bit too optimistic. I've managed to get TWRP onto my phone, but when I went to actually load a custom ROM into it, I found that it couldn't read anything from my sdcard.
I'm having what appears to be a common problem: when I boot into Recovery, TWRP asks for a password. When I cannot provide it (because I have no idea what it is), TWRP is unable to access the data partition. Apparently, the partition is encrypted and I have no way to de-crypt it.
I've found dozens of other posts by users having this problem and the solution everyone is giving is to fully wipe the data partition and start over. But I *can't* wipe the data partition, because TWRP can't access it and fails almost immediately. I have tried a multitude of options, including:
* Installing old versions of TWRP - same behavior; asks for a password, fails to wipe/format the data partition.
* Installing ClockWork's recovery - same thing; fails to format/wipe the data partition
* Flashing back to stock recovery, using that to format my data partition; this worked fine but as soon as I put TWRP back, the problem came back.
On my last attempt, I used the stock recovery to completely wipe the data partition, and made absolutely sure that it never booted into anything but Download or Recovery modes after that. I was hoping that would prevent the stock software from ever re-encrypting the data, but somehow, when I booted TWRP, it still can't read my partitions. Note that my phone itself is not "encrypted" as far as the Settings application is concerned, but apparently Android is doing something behind the scenes anyway. There doesn't seem to be any option in the stock settings to turn off this encryption.
Is there any hope for getting a custom ROM onto this phone?
Thanks for the help!
Any solution? I'm running into the same issue where TWRP is asking for a password.

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

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?

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 flashing a new ROM, TWRP doesn't decrypt the internal storage

I'm sure that this problem was asked a bunch of times now, but I didn't find any reliable solution to this so far.
I wanted to move from LOS to Omnirom.
What I did:
Wipe cache/system/date
Flashed Omnirom
Flashed TWRP (blu_spark_v9.96)
Reboot to recovery
But unfortunately, what I saw is that all of my internal storage is encrypted, and I don't know how to decrypt it back to normal without wiping it all to start from scratch.
By this time I tried some various tries to revert it back to normal.
But... obviously, I kinda broke it.
What I mean is that I've got the "stuck TWRP logo" and accidentally deleted to boot partition (I've already recovered them back (A/B)) but until I'll manage to decrypt my files, I'm stuck with the stock recovery and can only boot to TWRP, but not flashing it.
My question is:
What should I do next in order to return my recovery to TWRP and boot to my custom ROM properly?
