What? Xiaomi forum for oneplus 6t twrp?"

Nope, found the solution I needed in a Xiaomi forum and applied it to my 6T.

Has anyone managed to successfully restore a backup using the Q TWRP? With a clean fresh install of everything, generating then restoring a backup gives me the ol' error 255. I don't have the user 999 thing going on.

---------- Post added at 04:50 PM ---------- Previous post was at 04:24 PM ----------

It seems backup and restore works as long as you don't have a lockscreen set.

---------- Post added at 05:28 PM ---------- Previous post was at 04:50 PM ----------

Nevermind, seems it was just luck. Can't figure out what made it restore that time and not others. :(

If you back out 2 screens, there is a reboot option for recovery, etc after pressing "Reboot."

TWRP not installing after flashing latest OTA update. Can boot the img file from fastboot with no issues but no matter what install method i do, booting to recovery partition just returns me to fastboot mode. I have reflashed my update and managed to get the stock recovery to boot. Have repeated the process serveral times using recovery ramdisk method and flashing the installer separately. Even tried previous twrp installer i had used before trying to update to the lastest oxygenos.

i am on the tmobile variant of the oneplus 6t and flashed to the international(non branded) oos10 awhile back, with twrp and magisk installed. had no issues during the last ota update.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dwardo:
Yes I know as I have been doing that since I got my 6T... Does not change my suggestion...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] silverdrake11:
I am on oxygenos 10.3.3 and the official TeamWin builds which are currently twrp-installer-fajita-3.2.3-2.zip twrp-3.3.1-1-fajita.img

Neither the boot img (using fastboot) or the zip installs. So what I did was try the latest boot image in this thread for Android Q which was version 32. That did work and I got into the temporary TWRP recovery. There I first tried flashing the official build, then recovery did not work, it would take me back to fastboot like others have mentioned. So then I tried the latest zip posted in this forum, and same thing no recovery.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] henningsieh:
You should only use the v-32 files of the unified installer zip and/or the Q specific img from OP here, perhaps follow the install process step by step from scratch.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
I updated to 10.3.4 with no issues.. I used the simple TWRP method...I uninstalled substratum overlays before booting to recovery I didn't even have to disable modules..

Modules I use are.....

*Substratum.....

*OOS launcher w/left enabled...

*BusyBox NDK...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rippledrums:
I never disable Substratum overlays or Magisk modules and updates are always flawless for me with -32 TWRP.

Modules I use are:

Viper4Android

Audio Compatibility Patch

Audio Modification Library

Busybox NDK

Move certificates (for Adguard)

JoyPixels

Substratum

Overlays I use are:

Aether (for changing 4G to LTE on the status bar icon)

Ice (to change the Android Accent because it's not the same as the OOS accent, no idea why, and without it some screens have the horrible Teal accent)

I even do some manual debloating of Google apps I don't use via the TWRP File Manager, flash the India Fake Partition zip and use Omega Kernel.

I also always flash the new version to both slots.

Again, I never disable anything and everything just goes flawlessly and when I finally boot the system I have the new version with everything working as before.

:good:

[MENTION=4712355]mauronofrio[/MENTION]...i recently updated to oos 10.3.4. It has a new feature to enable work/life profile but is only available in India. Since i am using your fake partition deleter zip after flashing twrp v 32 to get rid of the cloud services, it seems it's also removes the work/life feature as well. So i am guessing the feature is not integrated to os and it might be part of the same India partition. Is there any way to only remove cloud service but keep d work/life feature.l??

Hey guys, I (really) need your help.

I'm not sure what I did wrong.

What I did is this:

1. Unlock your bootloader - DONE

2. Continue to install LuisROM

2. "TWRP update installation (manual):" . followed these instructions

Maybe I should do first "First time installation:" ?

I can no longer get into TWRP

The only option I see is Recovery mode -> ADB sideload. From there i can connect to PC

[IMG="ASD"]http://jalle.users.telemach.ba/share/2020-05-29_101108.png[/IMG]

What should I do? How at least to get TWRP back ?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
Did u already have TWRP before or flashed it for first time?

R you coming from Stock OOS or different custom rom?

Hope you are intstalling custom rom into both the slots.

If u r able to get into fastboot u can again flash the TWRP image through adb commands.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] BesoC:
1. Flash TWRP from ADB, reboot to recovery

2. Make sure that the latest OOS is installed on both slots. If you are on slot A, flash OOS and TWRP installer as batch, reboot to recovery and you will be on slot B, flash both again, reboot to recovery and you're back on slot A

3. You are now ready to follow the installation instructions of your ROM
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jalle007:
Really appreciate your response.

I used to have OnePlus 5, and RR install went quite smooth.

Now I am not familiar with concepts of A/B slots. Are they just partitions ?

I know I need to get TWRP working to be able to install LuisROM

But this is what i have now.

If you have some spare time I would give you Teamviewer access in order to help me with this issue. My skype ID : jaskotr1
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] BesoC:
You are in recovery mode, but trying to use fastboot command. It will not work. Phone needs to be in fastboot mode first. Enter commands in following order:

adb devices (make sure that your pc detects the phone)

adb reboot fastboot (phone should reboot to fastboot)

fastboot devices (make sure your pc detects the phone in fastboot mode)

fastboot flash recovery .....

Please also note that running 'fastboot flash recovery...' command only runs twrp. You will need to install twrp by flashing twrp installer after you flash your ROM as described in my first answer.

EDIT: Just noticed - LuisROM is Pie (Android 9). However, in your video you are using TWRP for Q (Android 10). You need to use the correct version of TWRP.

Hello everyone,

Coming from stock and first time tried rooting this device so i tried following the instructions in this post. Unfortunately, it seems like my device is now stuck at the "Press power key to pause boot" screen. I can go back to the stock recovery using the hard reset pushing all 3 buttons but thats it. Now i just want to go back to the stock oneplus 6t i had a couple hours ago :( . Could someone please help me in getting back to stock from this awful situation? Any help is greatly appreciated

Please check the reply from Besoc. He have already provided the instructions in depth. First thing to choose is correct version of TWRP image based on ur ROM android P/Q. Once you hve the correct image follow the steps from Besoc.

Hey, sorry for the offtopic, can you please give link regarding that Ice overlay or a screenshot perhaps? I've been missing out on Substratum ever since I started using OOS on 3T. Now I'm thinking to get back in the substratum game again :cowboy:

Found it on Play Store, but thought as the app description said it only supported upto Oreo, thought maybe you meant any other app. ;)

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] just4sc:
I tried looking in the 255 error thread but couldn't find a solution and was thinking maybe it has something to do with the -32 version of TWRP. I was able to backup ok however I found out later that I had forgotten to remove my security pattern prior to backup. Don't know if that's the issue but upon doing a restore I'm getting the dreaded 255 error. I also forgot to run magisk uninstall and don't know if that's the issue too (yeah, not a good idea to be working on stuff like this in the middle of the night and lacking sleep).

I haven't rebooted yet fearing I won't be able to get in.

I have since tried running the magisk uninstall (gave me an error - didn't write it down and now I can't see it anymore).

Tried installing magisk again (installed ok).

Install 10.3.4 ROM and that went ok.

Still not rebooted - thinking the install of 1.0.3.4 might have solved my problem I reinstalled TWRP -32 and then tried restoring my backup again. Of course I still have the 255 error.

I hoping someone has gone down my path or have some advise so that I can restore my backup.

Again, I still haven't rebooted yet so maybe that's my issue?

Edit: So, I rebooted and it gives me a crash dump. I can get into TWRP still but tried flashing the full 10.3.4 rom and it completes but it just goes into the crash dump again. I noticed while looking at Filemanager in TWRP all the filenames in storage are jumbled. Does that mean the encryption is messed up and I am hosed? I've tried searching but there's just so much information I'm a bit tired and am hoping someone point me to the right direction and maybe let me know if I can still recover. Thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] AquariumVitae:
On github a fix for that problem was announced for the next official TWRP release.

But if it will fix existing backups? From what I read, it will not, but then again I am not a programmer of that sort.

I didn't have they problem yet when restoring, but if I had, I would unpack the corresponding tar files for /data from TWRP backup and look for suspicious files with uid/gid or encrypted. Then, repack and `adb push` it to the device.

BTW, if you skip restore for /data, everything else might work

flash stock rom from twrp again
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] nitheeshas:
I have TWRP and magisk installed in my device. I wanted to unroot the device to check an issue with an app. However, after I uninstalled magisk from manager, the device always boots to TWRP. Doesn't even show the OnePlus boot animation. I was able to boot back to OOS only after flashing magisk back through TWRP. Did the boot image backup get messed up? How can I unroot my device temporarily?

Using Android Q, by the way.

Also, what does "Fix recovery bootloop" in TWRP>advanced do? Can I try it in my case? I don't want to mess up my data by performing unwanted steps, hence asking.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] baggord:
Hi everyone, I need help.

* bootloader unlocked.

* It doesn't boot. I've tried to flash a custom rom over stock oos after factory reset.

* I was on 10.3.3 OOS.

* Now, I can go into recovery via "fastboot boot twrp.img"

* TWRP doesn't ask for password and data is encrpyted. I've tried official one, bluspark's zip and none of them even boot twrp.

* This one boots yet the data is encrypted. I've tried "twrp decrypt 'password'" via twrp terminal. no luck.

I'm trying to decrypt and recover the data. Any help is appreciated.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] DarkSJ1998:
Flash OOS 10.3.3 again from TWRP & nothing else, it should boot up. And after one boot into the OS, you'll be able to decrypt /data in TWRP.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] baggord:
Well, the problem is I can't see the /data partition since it's encrypted. So, I can't flash OOS from TWRP. I am asking if there is a way to decrypt/save the data without formating it.

connect the drive and flash it

---------- Post added at 08:14 ---------- Previous post was at 08:11 ----------

Sew with the help of the drive, reset the firmware on it, connect and flash

twrp recovery

You can flash the firmware through a local update, the data will be saved, but the recovery must be set on a new one.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] DarkSJ1998:
You can do an ADB Sideload of the ROM zip, in TWRP, go to 'Advanced' > 'ADB Sideload' & Swipe.

Connect your device to PC using USB Cable

On your PC, type in 'adb devices' to see if the device is recognised, then put in command 'adb sideload <rom_file_name.zip>' and it should start the sideload.

Or you can use a USB Drive as [MENTION=5851797]Gensus[/MENTION] suggested.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] baggord:
I don't have an OTG for USB C sadly and adb sideload didn't worked. After swipe it took far too long. After 2-3 minutes, I cancelled it.

I've downloaded fastboot rom from mauronofrio and read about using "fastboot update images.zip" instead of "fastboot -w update images.zip". I lost all the data already, lol. Anyway thanks for help guys.

Hey guys tried to install twrp got it installed with adb/fastboot, flashed the twrp zip, flashed magisk zip everything was fine. Went to reboot and seem to be stuck in a boot loop. Not sure what I did wrong. Was hoping someone could help me solve this problem. Thanks.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
Check if are you are using the correct image. For the first time install of TWRP , you need to flash the correct image pie/q. Check if are using the right image. Then-

Flash image via adb, you sud be in temporarily twrp.

Flash the twrp zip.

Boot to recovery.

Flash magisk.

Reboot to system.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jules16v:
I see this on my device, too. The first time TWRP is installed decryption works, after that - zilch.

My advice is to fastboot boot twrp.img, then flash TWRP from the installer, cross your fingers and reboot. Worked for me.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] RuffyMonkey:
My op6t also is stuck in the recovery boot loop.

i have the latest update. if i boot from the q image. I still can't decrypt.

Flashing ramdisk or zip doesn't help.

I booted into the second slot. Luckily that worked.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
A/B works that way. But i assume you are now running on previous version of Android. Coz every time new update/ota installed its done on the other slot not the active one. If all goes well then android switches to the updated version. If not you anway have the active version. Its a fail safe mechanism.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] DarkSJ1998:
Yeah adb sideload takes time buddy, you shouldn't have cancelled it. It just shows "serving" percentage in the cmd/powershell/terminal window. It depends on the size of the zip.

Hi I have successfully rooted my 6T using the instructions.

Everything seems fine. My only issue is emojis, and some languages like Myanmar, Chinese.,etc..do not show correctly and appears as blocks.

Is there any way to fix this?

Good morning everyone.

I reflected the custom rom first by making a wipe system, then I reflected the image of the twrp, restarting it gave me the message that said no oss was installed I restarted the same and now it is stopped on the bootloader.

Not surprising since this message has nothing to do with how a device is partitioned. You needn't have looked any further than your own screen.

Do want to allow TWRP to modify System? Leave read only or swipe to allow modifications.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mad4some:
I'm asking what is recommended when flashing custom roms on this A/B device? Does it not matter in regards to the success or failure of the flash? Trying to avoid problems or brick is why I asked......I know what it says, which is generic.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
What's the difference between the Official and Unofficial builds. Previously, the Official builds had messed up decryption. Hence, Unofficial were preferred.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] -Duir-:
If your intent is to flash a custom ROM then you're not concerned about official OTAs and plan to modify System so picking read only seems pointless.

This feature debuted 5 years ago and IIRC ROM installs completely ignore the setting. Depending on how the installer script was done I think even some TWRP flashable zips that modified the system partition could even bypass the setting.

Even if you select keep read only and then run into an error flashing something later, you can just un-tick "Mount system partition as read only" under the mount options in TWRP.

I tried it, now it stuck on twrp logo, maybe it can't decrypt the /data userdata partition.

I have access via adb but don't know how to debug it. (logcat not found error)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:

Quick question about the decryption issue. What does this mean exactly? Like, it can't decrypt the device to flash anything? I'm a noob with this, so I apologize in advance. Thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
You can flash files but only with a otg cable or with adb, failing the decryption you have not the access to your internal storage
