Hello all-
In the process of trying to upgrade to OOS 5. I made sure to make a backup of the entire system (system image) in TWRP before proceeding. I also backed up the Boot image and Modems. I had the entire OOS 5 rom ready to flash but before doing so I elected t wipe Dalvik/Cache, Cache, Data & System as I always thought you have to do a fresh clean install when changing versions (7.1.1 to 8.0). The first error I encountered was that it couldn't flash the file. Then when I tried to restore my backup...it does the process with no errors yet when I try to reboot I am told no OS installed. What has happened and what can I do since I always make these backups to be safe?
Thanks all!
Plug your phone on a PC (with the phone in recovery mode), move your backup (sdcard/TWRP/backup) on your PC to keep it safe. Next follow the mega unbrick method 2 (just Google it) on OnePlus forum, update your phone to the version that you were and reflash TWRP and copy your backup from your PC to your phone (in the same location than before) and try to restore your backup.
Error installing OOS 5
Thanks all! I thought a System Image backup was all I needed and had no idea I also had to restore my Boot Image backup. Once I restored that backup I was good to go. Oddly though I didn't have all my apps and data on the phone like I thought the system image backup would have. Honestly I don't care as long as I have a phone again.
On a side note, I have the full OOS 5 ROM on my phone and when I try to flash it I receive an error. The error message states as if the file os for a One Plus 3 and that it cant confirm what my device is? I have always downloaded the full ROMS from OP site and nver had issues upgrading in the past. Any ideas? Does the version of my TWRP matter? Please advise.

System image is rarely useful, it's a full Byte by Byte backup of the system partition ( meaning even the empty Bytes are saved). System partition means that boot one isn't concerned. And system partition means that data partition isn't concerned either, so no user apps or data.
Better to stick to /boot /system and /data backup.
You must have latest official TWRP 3.2 for Oreo ROMs. Or blue_spark latest (8.61 version see blue_spark kernel thread OP)

Thanks man! Good information to have moving forward. No sense in backing up partitions that are not useful and only take up space. Can I update to TWRP 3.2 right in the TWRP app or should I download image and flash within TWRP? I am currently on SU 2.82....is that compatible with Android O?

Yes update from within TWRP. I think superSu 2.85 should be good or Magisk 14.0
Cant recall so many partition options in my earlier phones, but with Oreo 8.1 on Rn5 I find these:
boot, cache, data, recovery, system, system image, vendor, vendor image, modem, efs
In all, 10 backup and restore options. I understand data and system are the main ones for backup and restore. And for safe keeping modem, efs as separate backup to the side (not used in regular backup/restore operations).
What about all these new partitions I'm seeing? system image, vendor, vendor image? If I am backing up 9.5.19 and moving to (miui 10) 8.8.23, is data and system all that is required to backup? Will 8.8.23 (fw-less rom) affect these new partitions mentioned? So to restore 9.5.19, just restore data and system and that is enough?
Much thanks.
Hello
This is a TWRP recovery for Motorola Moto G5 Cedric for arm64 ROMS, with encryption support, backup support for persist and efs partitions and possibility to flash/backup logo boot image.
I need review and test, especially for the storage decryption and/with LineageOS fingers-crossed. I was able to test it on my device (XT1676 3Go).
It is my first ROM so it is possible that there are bugs.
- Be carefull, there are problems with the backup system :
Just wish to come here and tell you guys to AVOID using this recovery, it seems to have a serious bug.
I just backed up my entire data partition (and enable digest verification) and restored the partition afterwards and the phone didn't boot.
Then I tried restoring it with verification enabled and the hashes didn't match.
In other words, for some reason, the generated backup was corrupt.

Akipe can u help us to build treble rom for cedric???
Works nicely, thanks.
I just tested it and it decrypts my internal storage normally.
Just wish to come here and tell you guys to AVOID using this recovery, it seems to have a serious bug.
I just backed up my entire data partition (and enable digest verification) and restored the partition afterwards and the phone didn't boot.
Then I tried restoring it with verification enabled and the hashes didn't match.
In other words, for some reason, the generated backup was corrupt.
Of course I could make another test but it'll take just a long time to backup everything again, so if anyone wants to test it, feel free, but beware, you could have a hell of a headache finding out the backups you made were useless.

I have backup up data partition from my TWRP, reboot one time to recovery, restore the data backup with digest verification, and reboot to LineageOS, with no problem (my rom is LineageOS 16.0 without encryption.)
I think there may be 2 errors (maybe more) :
1) There is a problem with data restore when encryption is enable. I can not test this scenario for now, but i will do it as soon as i can
2) Was your backup stored on your SD card? if so, it is possible that the sd card may be damaged, because it is too old or of poor quality (more info here : https://photo.stackexchange.com/questions/40489/what-causes-an-sd-card-to-go-corrupt )
if you have other information or other ideas, do not hesitate to share it!
if people want to participate, try to save the data partition and restore it, especially with the encrypted partition :good::good:
be careful, make a backup of your data before test

I agree it may be any of the 2 problems.
My data partition was indeed encrypted, and yes, my SD card is not what I would call genuine, though I think that's not the case since the card is relatively new and I never had any problem related to data corruption.
Anyways, thanks for your effort.

I have test backup the data partition with encryption on LineageOS 16 (arm64), backup and restore work without issue
What ROM did you use when you made the backup, and with what arch (arm or arm64) ?

I was on stock oreo, so its arm, not arm64

Oh ok, there are chances that's why the backup did not work .
This recovery is mainly intended for arm64 rom !
Just wanted to say that everything worked well for me in backing up and restoring the OmniROM, on both decrypted and encrypted phone.
Thanks @Akipe for the great job
Can you update it to latest TWRP?

forgot password to decrypt??
hi,
first, sorry if this is the wrong place to post this. right now, when i install the 64 bit twrp i am asked for a password to decrypt my data. i have tried some passwords i think i would have used, but those don't work and i get a message also saying that the default password didn't work - i haven't typed a default password, though, so i assume there is a default one that twrp tries automatically. in the past, i did try a rom requiring 64 bit twrp and i am guessing i set a password other then the default to encrypt/decrypt, but i went back to stock without issues so have not thought about the password and cannot remember what i would have used. i wanted to try dotos on my phone, which i assume requires 64 twrp because i got error 255 when i tried to flash without twrp64. so i installed twrp64 but cannot get any further. so here are my questions:
is there any way to decrypt the data if i forgot my password?
if not, can i format the data while encrypted to install the new rom? if i can do that, what should i back up? i have pictures and other necessary files backed up, so i am not worried about completely wiping the phone to start over. however, should i back anything else up before formatting? do i need to worry about losing imei or losing any partitions that would make phone inoperable or not have any signal? should i back up with twrp64 or the non-64 bit twrp currently installed? any help or point in the right direction is greatly appreciated.

You need to format data
Push back button when it asks for decrypt
Goto wipe and select the option on the right to format data
This will erase everything on internal storage so copy any files you want to keep to pc first (pictures music etc)
Once formatted data restart back to recovery to check encryption has been removed and data partition is mountable
TWRP backups do not save personal files (pictures music etc) They only backup data and system files (and other named partitions)
Once you have flashed a new rom you can encrypt again if you want to via the security settings menu in phone settings

thanks for the quick response! and just for clarification and for me to be sure, should i back up any partitions before formatting? right now i have 32 (or non64 i guess) bit twrp installed, stock rom and bootloader unlocked. do i need to take any precautions with data/imei/signal before reinstalling twrp64, formatting data, and installing a new rom? if it matters any i have the international version of the moto g5. thanks again!!

Backup efs if you want to preserve your current emei state or need to restore it in future
A question about decrypting your device, in this case Luisrom Android 10, but would most probably count for other roms too.
Did not try it already but would like to decrypt my device and would like a confirmation if the following is the right procedure without doing a new install:
Boot in recovery
Make a backup of /data to internal storage with TWRP
Make a backup of internal storage to my pc
Format data in TWRP
Copy internal storage back from pc to OP3(T)
Restore backup from /data with TWRP
Reboot with decrypted phone
I could do a dirty flash afterwards ofcourse, but because /system is not touched I think the steps above should be enough.
Could someone confirm if this is right?
Just tried what I described above but seems not to work.
After reboot, phone is starting again with encrypting and after next reboot everything is encrypted again.
It also seems as if Android 10 (read it somewhere) is using file based encryption, so not only on a higher level...
So for now, I only see a fresh install as the solution.
Would someone know another solution to keep your data without doing a fresh install it would be nice to know.
Any input is welcome!

First of all: decrypting is what happens on each reboot if data is encrypted. Decrypting is making something encrypted readable again. Removing encryption is something completely different.
For your question: which rom are you booting? This sounds like you are using a rom with forced encryption enabled. Dosable forced encyption in fstab before first system boot.
You can't use fbe with op3/t. No blobs, no twrp... Either you havn't read closly enough or you belived some ignorant not reading closely enough: g requires new devices shipped the first time with q to use fbe. All devices shipped originaly with fde can still use fde with q.

I am using CrDroid 6.4 Luisrom which is not enforcing encryption, just as most other custom roms.
I had enabled encryption though after installation to see if encryption was working already for installing CrD Luis on my work phone (where I want encryption).
After that I decided to go back to unencrypted, following the procedure above, which did not work.
Did not make the link between fbe and file based encryption, but ofcourse this is the same and not available on op3/t.
Must have been sleeping when I wrote that.
Based on what you wrote and my missing knowledge;
After encrypting, is fstab changed also and would the solution have been to change fstab back also before rebooting after restore?

No. fstab isn't changed during encryption, neither for forced encryption nor for "voluntary" ( ) encryption.
Maybe the problem is the restored data itself: the rom setting for encryption is restored as well if you restore the data unconditionaly... Perhaps this way the reencryption is triggered. Did you try to boot the rom without restoring data? If it's unencrypted on a clean boot, but is (re)encrypted after first boot after restoring the backup, you have the answer. If it's encrypzed on a clean boot, formating to remove the enctyption has failed.

Good point, did not try that unfortunately and just did a fresh install so.... not really eager to try it now
But I think indeed reencryption was triggered because of also restoring the encryption settings.
Will try it when I have some spare time and want to take the risc of a fresh install again
