Encryption issue after flashing LineageOS 14.1 and SuperSU

Hi
I'm having this very weird issue with my phone (A2017G). I unlocked BL, installed TWRP, updated to TWRP 3.0.3-1, formatted data, factory reset, install A2017G_Nougat_Bootloader+ModemFix, factory reset again, install LineageOS and then boot. The device booted fine.
I noticed root wasn't built-in so I flashed SuperSU V2.65. After a reboot, my phone won't let me boot into the system anymore. I get asked for a password. Whatever password I enter, it says "Decryption Unsuccesful. The password is correct, but data is corrupt". When I reboot to TWRP and format data and then factory reset, nothing changes. I keep getting the prompt before system boots. Even re-flashing the bootstack and lineageOS doesn't help. I know flashing anything else will brick my phone, so I refrained from doing that.
What am I doing wrong here?
Note that TWRP reads both my internal storage and my SDcard. However, internal storage contains only the folder "TWRP". When I go up a level, I can see the normal folders like "boot", "cache", "data", "dev" and so on. In the "backup" menu, DATA also shows as "0MB"
File system says "f2fs". Do I repair/change it?
Thanks

Ah,
I have/had the same error. Looks like this needs to be changed to ext4.

I would say the answer lies with issues between f2fs and SuperSU

And you flash the wrong SuperSU, the one needed is either v.2.79 or v.2.79-R3. try booting back to TWRP and clean Flash Lineage again and flash either one of the SuperSu I Mention before.

I have the same after install unofficial lineage 14.1 'decryption unsuccessful'
On TWRP 3.0.3-1 I go in 'wipe', then 'advanced wipe' and select 'Data', press 'Repair or Change File System' and then 'Change File System' to EXT4
That's work fine on my 2017G
For root
download.lineageos.org/extras
The arm64 zip
After install with TWRP go in deployment options and activated it!
Lineage is running with root

Thanks, everyone. That worked. I was quite worried for a while, I really don't want tot RMA the device a second time due tot me messing things up.

Where do I find the options in Twrp for deployment

Probably it is caused by a known bug in the f2fs implementation in the kernel. Only @Unjustified Dev can solve it. Some people who already was using f2fs with TWRP 3.0.4 and LineageOS 13.1 are not having those issues and they were able to dirty flash the new LOS 14.1.
Updating to TWRP 3.0.3-1 is very recommended. TWRP 3.0.2 has some problems when flashing zips. SuperSU is one of them.

i m ****ed

I tried to flash xXx_NoLimits_4.4_OP5_Oxygen_OB01_full (1) my op5 got into a bootloop. and theres nothing left in the phone. twrp shows nothing. cant copy any file from pc when i try to shows an error that cannot copy item-the device has either stopped respondingor has been disconnected.

You can't reboot into bootloader?

Probably best to factory reset through twrp, flash oxygen is 4.5.14 to go back to stable os.
I don't think this needed a new thread^^

Boot into twrp, wipe using "format data" which will wipe your internal storage (since you've already lost your files, you won't lose any now :3 ). And your phone should boot after that. Switching to oreo from nougat needs a "format data" as of now, afaik. Also NOT using the official twrp is recommended.

What TWRP version did you used?

If you've lost everything then just do a "fastboot -w" from command window, then "fastboot flash recovery TWRP.img" (With whichever TWRP build you want to use), then reboot into TWRP and it should appear on your computer as a mounted drive, then copy your stuff over and flash it using TWRP.

Well, the title is misleading. I didn't expect a query.
P.S.: Best to post in the dedicated thread for the ROM. There are more people that can be of help.

Boot in twrp and go in wipe section on twrp and tap on format data then type yes and your phone recognized back on pc and you will be able to copy files on it :good:

Boot fastboot, flash stock recovery, boot it, erase and wipe every thing, boot fastboot, flash TWRP 3.1.1 , copy your rom and flash your rom.
Sorry for my bad english

Go to TWRP, Wipe then to Advanced wipe, Click Data then choose Repair or Change File System, Change file System. Click EXT3 then Swipe to change. after that choose EXT4 and Swipe to Change. hook phone to pc/mac and tranfer your file zip to your phone and reflash it. *this might or might not work. everything will be deleted from phone*.

How can I install Oxygen OS 5.0.1 with an unlocked bootloader?

Good day!
Our country just received the Oxygen OS 5.0.1 update.
How can I install it with an unlocked bootloader?
I was going to relock it but I found out that if I did, my data will be gone.
The only difference in the set-up of my phone from a stock OP5 is the unlocked bootloader.

Flash through stock recovery

I haven't done this kind of thing yet.
If I do this, will my data be wiped out or not?

What about using the OTA notification ?

What do you mean?
I tried to update my phone using the normal way but after downloading and tried to install it, it failed because my bootloader is unlocked.

I just made a backup of data using codeworkx recovery. Copied the backup (Along with the files on userdata I wanted to keep) to my PC.
Wiped all and formatted data. Then installed Oreo and copied back the files and data backup from the pc to the phone and restored data with codeworkx recovery again.
Then flashed magisk 15.2 and rebooted.
Everything working fine now.

I managed to flash Nougat without locking my bootloader. But I also had to Format the Data partition to make it work. I used Titanium Backup to backup the data of the Apps and Myapplist to make a list of the apps. After installing Oreo I only needed to spent 1 hour to restoring the app data.

Hello, I'm interested in the same thing.. I have oxygen osv4.5.x received notice for is 5.0.1 and want to install. I have an unlocked bootloader and am also rooted w/magisk. I want to keep my unlocked bootloader and root after upgrading. I also want to do a "clean" install.

This is what I did:
Downloaded OnePlus5Oxygen_23_OTA_028_all_1801031502_04d7cc5. zip, twrp-3.2.1-0-universal-codeworkx-cheeseburger.img and Magisk-v15.3.zip.
Rebooted to TWRP and installed the Codeworkx TWRP using the Install->Image option inside TWRP.
Rebooted to TWRP again to make sure that my TWRP was updated.
Entered WIPE from TWRP main menu and used the 'Format' option to Format the Data and typed 'Yes'
This deleted my Internal Storage so I had to backup everything beforehand.
Then used advanced wipe to wipe Cache and Dalvik.
Mounted the internal storage by using the Mount option from TWRP main menu.
I was having problem copying files to the internal storage so I rebooted TWRP and the problem was fixed.
Copied the OnePlus full update and Magisk zip file.
Installed the OnePlus full update and Wiped Cache and Dalvik and rebooted the device to make sure that the OS boots.
Then rebooted the device to fastboot to flash Codeworkx TWRP again because it was unavailable.
Booted into TWRP and flashed Magisk.
I am now on Oreo and I hate the way Ambient Display looks right now.

I honestly dont see a big difference yet, but only had it for two days. Feels a bit snappier, my signal a bit stronger, and probably an improvement with battery life. I had issues upgrading but then again I flashed the wrong version of magisk. I think the most important thing is the latest android security update.

Hey, thanks.. I will update later today. I see you provided which version of twrp (twrp-3.2.1-0-universal-codeworkx-cheeseburger.img). But what is the difference between the version you noted and the one I found (twrp-3.2.1-0-oreo-8.0-codeworkx-cheeseburger.img)
I want to make sure I have the correct version.
Thanks again

You can ask that question on the TWRP thread. May be they can answer it correctly. I guessed that twrp-3.2.1-0-universal-codeworkx-cheeseburger.img was for both Nougat and Oreo and that is why I used it. So, if you want to be sure you should ask that on a TWRP thread.

Hello, I was reviewing the process and just downloaded everything onto my computer and transferred onto my phone but have a few questions regarding some of the steps.
* Rebooted to TWRP and installed the Codeworkx TWRP using the Install->Image option inside TWRP
** Can I update TWRP via the official app and is that version of TWRP okay to use over the "twrp-3.2.1-0-universal-codeworkx-cheeseburger.img"
* Entered WIPE from TWRP main menu and used the 'Format' option to Format the Data and typed 'Yes' / This deleted my Internal Storage so I had to backup everything beforehand.
** How, what and where did you back up your data? Because later you mentioned "deleted my Internal Storage". I am guessing that because the OP5 does not have an external SD card everything is wiped and the new OS 5.0.1 needs to be saved onto a computer and then re-transferred back onto the phone. I am also guessing that the backup will need to be saved onto a computer as after wiping the phone it would also delete that file too, correct?
* Mounted the internal storage by using the Mount option from TWRP main menu.
** I am assuming that this option after the data wipe is self explanatory?
* I was having problem copying files to the internal storage so I rebooted TWRP and the problem was fixed.
** This is what makes be believe all the files should be on a computer. How did you reboot and when you did, does it go directly / back to TWRP?
* Installed the OnePlus full update and Wiped Cache and Dalvik and rebooted the device to make sure that the OS boots. / Then rebooted the device to fastboot to flash Codeworkx TWRP again because it was unavailable.
** I am guessing here that once OS v8 is installed the TWRP img is no longer on the phone. I would need to transfer the TWRP back onto the phone then re-flash? Could I just install the TWRP official app and flash that way?
Thanks

Yes I am currently rooted. Once I flash the new OS will I still have root access to use the TWRP official app? Is that why after flashing new OS you need to flash TWRP via fastboot?
What about the backing up? I also have full titanium, thanks.

I received the following tip
"Wipe data and then copy the rom full zip flash it boot it to the starting screen then boot to recovery and then flash magisk ,you will see no errors."
But this makes no sense to me.
I have formatted my phone / wiped data / have the full rom & magisk on my "/sdcard" / went to install zip via TWRP, selected the rom and received the error message.
I decided to just go and upgrade via OTA and that failed. My phone has rebooted back to stock
what am i doing wrong?

Im not sure what instructions are you talking about but this isnt the first time i root my device.
Im using TWRP 3.2.1 since the last version giving me a little problems when trying to root. Im using the last magisk version.
About dirty or clean.. I first tried just flashing nornal from the OTA and then after it worked (no wifi or LTE) i tried to do factory reset and root again

Try flashing this first https://sourceforge.net/projects/cheeseburgerdumplings/files/16.0/cheeseburger/recovery/
Download ota again and clean flash it from the recovery.
It might be because your TWRP isn't compatible to Pie. Most people here including me tried codework's TWRP and it solved any of our issues.
Edit: after flashing magisk reboot your phone once more. (i didn't knew it before. I booted into my os and checked magisk app to see if root was successfull but it didn't show me. I wiped everything down and flashed magisk again. Same thing happened. Rebooted my phone and saw root was on )

I would suggest do a complete clean install (wiping everything but USB OTG) and making sure you got the latest TWRP from blu_spark or codeworkx. Also flash it following these instructions:
[Clean Flash] For Users with an Unlocked Bootloader and TWRP Recovery:
- Download the full ROM zip from the downloads section above
- Transfer the zip to the root of your device's internal storage
- Only needed if you are coming from Oreo or if you use an old TWRP recovery that's not the latest and Pie compatible: Remove the compatibility.zip from the downloaded full ROM zip with either MiXplorer or Total Commander (not with any other tool!) on your device itself
- Reboot to TWRP recovery (make sure you're using siankatabg's TWRP if you're on Oreo or codework's TWRP/blu_spark TWRP if you're on Pie) and take a nandroid backup of your existing ROM
- Flash Magisk Uninstaller (recommended)
- From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache, cache, system, vendor and data> Swipe to wipe
- From the TWRP menu, Install > Select full ROM zip (modified one with compatibility.zip removed, in case you're on Oreo or unmodified one, in case you're on Pie) > Swipe to flash
- Flash the latest stable Magisk in case you want to root
- From the TWRP menu, Wipe > Advanced wipe > Select dalvik-cache and cache > Swipe to wipe
- Optional: If you wish to decrypt, format data via TWRP (please note that wiping the data partition, which we did in the 5th step above, is not the same as formatting it) and after that flash Disable DM-Verity and ForceEncrypt 2.0 (OP5-5T-Treble).zip from here
- Reboot
Full instructions and downloads from -> https://forum.xda-developers.com/oneplus-5/how-to/official-oxygenos-4-5-2-7-1-1-ota-t3627003

i ended up giving up..
im trying to do a clean flash
but the moment i flash the recovery and trying to go into the recovery
boom
black screen
i tried it multiple times both with codework 3.2.3 and blu_spark
Edit: Flash universal codework 3.2.1 does get me into recovery
im gonna restore my backup...for now

For the "Clean" Install given that OnePlus5 doesn't have external microSD storage, will ALL data (photos, documents etc) on the phone be erased in Step 6 above?

No, it wont because all of that is stored in the Internal Storage. So as long as you don't check that, you will still have your data. However, I personally wipe everything including the internal storage when moving to a new rom. I prefer to start with a complete clean slate but it is optional.

TWRP and Decrypt?

Hi.
I am new to the Nexus 6p.
I want to install Magisk and backup my ROM via TWRP.
I am running stock Oreo 8.1.0 with a password and fingerprint.
I have just unlocked and installed TWRP 3.3.3-1. When I first loaded TWRP it asked me to decrypt data, but I just cancelled it as I thought it wasn't needed. I take it this is wrong?
I have now tried to go back into twrp but I get the Android on its back saying 'no data'. So the twrp flash never stuck.
I am under some confusion whether I need to format userdata or not. The guides I am following are old and don't mention Oreo only Developer preview N. I would prefer not to but if it needs doing it needs doing.
Would removing my fingerprint before flashing twrp help?
Thanks.

You need to boot back into twrp and format data the reboot back to recovery again and advanced wipe system data cache dalvik/art and internal storage if necessary, then flash a custom ROM .
