I'm not sure why that version would freeze. You aren't trying to fastboot flash boot are you? And using that specific twrp I posted?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] pr3dicament:
Nope. Fastboot boot. I had to use the crdroid version posted on page 218. I tried all of them from there on up, 3.5 seems to be the one that works.. the "crDroid" recovery.. nevertheless, it works, just not version 3.6.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Brettroth:
The normal 3.6 doesn't but the one I posted I thought does. Did you download that one?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] pr3dicament:
Yep. Doesn't work.

@mauronofrio thanks for TWRP for enchilada and fajita.

I'm curious as to why latest enchilada version (3.6.x) is now A11 based whereas for fajita it is still A9 based ? Thankful if you can shed any light.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] b8842dc0:
I know that official TWRP doesn't support A12 data decryption. Is that also true of unofficial?

Thanks!

Hello friends, I haven't updated my op6t in a while.

As of now the OOS version on my mobile is 10.3.12 and it is rooted with the latest Magisk version 25.1 and the latest TWRP version 3.6.2_9-0.

I would like to update my OS to the latest OOS 11.1.2.2.

could someone kindly let me know if any procedure has changed for the update to the new android 11.

I don't want to lose any data or brick my phone.

This is my usual update procedure for reference

[Files-

TWRP-3.6.2_9-0.zip,

OOS-11.1.2.2.zip,

Magisk-25.1.zip]

0-Reboot to TWRP

1-Install OOS

2-clear dalvik

3-Install TWRP

4-clear dalvik

5-Install Magisk

6-clear dalvik

7-Reboot to TWRP Second Slot(A/B)

8-Install OOS on Second Slot(A/B)

9-clear dalvik

10-Install TWRP

11-clear dalvik

12-Install Magisk

13-clear dalvik

14-Reboot to TWRP First Slot(A/B)

15-Install Magisk

16- Reboot to system

So Do I need to change anything or continue with above method.

Thanks in Advance.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
Steps looks good. There is no major change in upgrade of A10 - A11 apart from how root is managed in newer versions of Magisk. As a precaution may be it's better to disable any magisk module which has system level tweaks. N even better to have a backup of data since you r jumping to newer Android version. All d best.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] DaOldMan:
The repetitive clear dalvik has no logic. It's like formating a hard drive 3 times like the first one isn't good enough. Just do it once on each slot. I don't even know if it's necessary.

If it was me I would upgrade using the internal update system. It causes 0 problems and always works. I think I wrote it here how to do it, so just search back mate. It looks like this:

Before updating to Windows 11 fastboot worked fine. Now I get: "fastboot : The term 'fastboot' is not recognized as the name of a cmdlet, function, script file, or operable program......"

I have tried "googeling" it but didn't find a solution. Anyone know how I can fix this?

Thanks in advance! :)

Solved it.

Instead of opening a terminal or Powershell inside the fastboot folder I hade to go up a level and right click on my fastboot folder and open terminal.

Don't know why it worked this way and not by right klickning inside the folder and open terminal...

Hey stupid question. Last phones I rooted and flashed was the N5 + N6. Had no issues with TWRP. I am attempted it with my 6T. Have it unlocked. when I "fastboot boot ""twrp.img"' I get a qualcom error screen with a message "attempted to kill init". I have also attempted the same "fastboot boot "lineage-recovery.img"" and it just reboots it self. Am I doing something wrong here? I have tried two different official versions of twrp and the latest unofficial.

Anybody following this thread over here:

Looks like they are linking to TWRP builds for fajita that work with decrypting A12. Anybody tried these builds out? Curious whether mauronofrio is no longer the main TWRP fajita dev? Looks like those builds are being handled by somebody named siddk.

I'll answer my own question. I'm now using the TWRP found at https://xdaforums.com/t/recovery-11-12-unofficial-twrp-for-oneplus-6-6t.4382121/

Hello

-1) My prerequisites: OnePlus 6t unboxed. initial setup. Search for updates. Android-Version: 11. OxygenOS-Version 11.1.2.2. No PIN set. Bootloader unlocked. adb and fastboot tools are working with linux.

0) I'm going through the official lineageos installation guide an wondering, why there is no mention about a twrp recovery. So I stopped the further LineageOS installation at this point.

1) What is the difference between twrp and lineage-19.1-20220908-recovery-fajita.img? Both can be installed temporarily and then persistent if I got it correctly.

2) On an previous OnePlus 6T device I bricked it with fastboot boot twrp-3.6.0_9-0-fajita.img so I will avoid to brick the second device.

3) Is lineage-19.1-20220908-recovery-fajita.img really necessary to install or can I skip this and keep going with twrp?

3.1) If 3) = yes, than which twrp version should I install?

4) This forum twrp installation guide point 4: fastboot boot recoveryimgfilename.img means twrp-3.4.0-11-fajita-Q-mauronofrio.img?

4.1) Can I install instead of twrp-3.4.0-11-fajita-Q-mauronofrio.img rather than twrp-3.6.2_9-0-fajita.img from the "official" twrp download website?

5) What exactly are point 7. and 8. "Install Recovery Ramdisk" and "Choose the recoveryimgfilename.img" - does it mean that twrp will be installed persistently instead temporarily?

Thanks in advance

Can someone help with an updated guide?

I receive crashdump when I try to follow the first page instructions (when `fastboot flash boot twrp-3.6.2_9-0-fajita.img`)

can someone help me out on what I should do?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
Depends on your previous setup and sequence of steps you followed.

R you coming from custom rom or stock?

Do u had any previous versions of TWRP on any of the slots or installing it for first time?

Did you tried with any previous versions of TWRP?

As far as steps are concerned they are still the same and haven't changed much.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] esseti:
In the end i was able to use the other one that can be found on XDA `TWRP-3.6.2_11-OP6xT.zip`. This one runs.

I had Oxygen stock before.

what I did was to fastboot boot the TWRP . i've tried 3.2.3 3.4 etc

should I instead install this?

Beacuse the other one does not allow me to do backups (which scares me a bit)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Flieq:
Hi . I have problem to flash the TWRP . Everytime i fastboot boot “image file” my phone goes into crashdump mode . I have tried using msm tools redo the whole process back . But still didnt work
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Brettroth:
Forget msm tool. Just use the right twrp. Try this one.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Mr.MEX:
When installing on the above android 9, the ability to download the image through the fastboot disappears boot and recovery. If you need to get into recovery mode, you need to patch the stock boot image, then flash it through fastboot, and then run command fastboot reboot recovery. there are no other options.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Mr.MEX:
To exit crash dump mode you need to set "-" + "+" + "power".

I just downloaded the IMG+ZIP files for TWRP 3.7 from the offical TWRP site and installed. Working nicely till now
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] FullWipe:
Hi, I updated my oneplus 6t from Android 10 (10.3.7) to the latest version available (11.1.2.2).

I updated in the classic way via local update, don't reboot, flash TWRP via Magisk Manager, don't reboot, flash magisk (after OTA).

The update was successful but I immediately encountered a problem in TWRP recovery (9.6.2 official) where the decryption failed.

In truth, it didn't even ask me for the PIN and the files are not decrypted.

I need to flash some zip mods and i would like to have a backdoor in case of problems with substratum and Magisk modules but I find myself stuck in this state.

I tried other TWRP's versions including this one too but had crashdump issues.

Then I tried to redo the update from scratch but the problem persists.

I've read that many have had similar problems but no one who has reported how they solved it....

Could someone who has been in a similar situation explain to me how to fix this please?

Thanks a lot!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
If you have TWRP installed why do a local upgrade. You can directly flash the zip in TWRP itself followed by TWRP zip. Magisk is optional if you want to root. In trying to retain root following conventional way you might have corrupted your boot partition. If your device can go to bootloader mode try flashing stock boot image and see you can come out crashdump mode. If that doesn't work may be MSM tool only option.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jamiehawman:
hi im new to rooting and things i have however done the adb fastboot oem unlock etc all done well im just confused on which twrp to use as of today for my oneplus6t 11.1.2.2 a11. ive downloaded the latest majisk 25.1 but i dont have a clue what twrp to download theres so many comments and people having problems, mines the duel sim model so i beleive its not the tmobile varient. any help would be great thanks ive seen people say 3.7.0 but then say no because thats for android 12
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jamiehawman:
hi brettroth do i just fastboot boot this file img will this have all the file names normal, but then what twrp zip do i install :/
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Genlead:
When I flash this twrp.img, I can't permanently install twrp from the zip because the internal storage is encrypted.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Brettroth:
So when you boot that twrp.img you need to use sideload with the PC or a USB OTG and flash the right twrp zip that will decrypt.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Brettroth:
This zip should decrypt on a11. If not let me know I have others I know one of them works.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Genlead:
I just installed via sideload and my internal storage is still encrypted.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Brettroth:
Try this one lol. I am on a13 and this decrypts. I don't wanna go back and test things but I'm pretty sure there was a twrp that decrypted a11. A12 and 13 works no prob

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Penguinpee:
I'm looking for help recovering from my own stupidity. I was planning to update the LineageOS on my phone. It also has/had Lineage Recovery installed. I wanted to make a backup using TWRP and for that I wanted to boot briefly into TWRP's recovery.

I tried booting TWRP using fastboot boot twrp-3.7.0_9-0-fajita.img.

Sending the image went through, but booting failed with FAILED (remote: 'Unrecognized command boot').

So, I decided to flash the image instead with fastboot flash boot twrp-3.7.0_9-0-fajita.img. That worked. But after rebooting an error was shown. Something like "init exited". I didn't take a note. I rebooted again, expecting it to fall back to the other partition. But it didn't. Same error was shown again.

Finally, I attempted to reboot into recovery, holding VOL DOWN + POWER. The phone/screen would turn off, but it wouldn't reboot at all. Now it doesn't show any sign of activity no matter what buttons I use to try to boot it.

Have I successfully bricked my phone? Or is there something else I could try? I'm hoping for the latter.

UPDATE:

I managed to start the phone with VOL UP + POWER (holding for an unusual long time). The error message reads:

QUALCOMM CrashDump Mode
-----------------------

Attempted to kill init! exitcode=0x0000000b complete_and_exit
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Timmmmaaahh!:
Lesson learned: don't flash a recovery img that doesn't boot. Have you managed to send fastboot commands to the device? If at all possible, flash another TWRP version. Otherwise, try this Msm tool (for T-Mobile, use this one instead).
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Penguinpee:
I'm not quite sure what you mean by "a recovery img that doesn't boot". Is that what the FAILED (remote: 'Unrecognized command boot') was trying to tell me? That the image cannot be booted? That would indeed be a hard learned lesson.

In CrashDump Mode fastboot appears not to be enabled. I see the device being recognized by the kernel with different vendor and device id when connecting USB. But fastboot devices doesn't list any device. The described VOL UP + VOL DOWN + POWER to enter fastboot has so far been unsuccessful.

Should I be able to get into fastboot, I could go back to flashing Lineage Recovery image or an older version of TWRP (provided that works. Or maybe switch the device to the other slot?

But, if not, it will have to be MSM Download Tool. Gotta find me a Windows Box first. Or is there a Linux alternative for / port of the tool?

Anyway, thanks for your reply. I'll keep looking, carefully trying things out. I'll keep ya posted on how things unfold.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Timmmmaaahh!:
Yes, that would've been the cue for me to try another image.

Actually, yeah, fastboot should still work but things can go wrong I guess. That's the entire idea: when the recovery partition gets corrupted it should be possible to flash another one via fastboot. You may need to flash an official 1+ image first. Not sure how you'd switch partitions without fastboot. I'm afraid msm only works in Windows, nothing a VM can't handle.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Penguinpee:
All right. I made some progress. I'm able to boot into recovery mode and I'm also able to boot into fastboot/bootloader. Not sure why that failed earlier. But it works now and there's hope.

I think I know where I took a wrong turn earlier. In recovery mode there's an option in the menu "Enter fastboot". I believe that's what I did before. I'm unsure what exact mode the phone enters using that option. I probably have to ask the LineageOS folks. Anyway, in that mode I'm unable to boot a recovery image using fastboot boot, no matter what recovery image I choose. The second step will always fail with 'Unrecognized command boot'.

The option below in the "Advanced options" menu of Recovery reads "Reboot to bootloader". Selecting that, the phone will reboot into "FastBoot Mode". Now the device is listed using fastboot devices and I can use fastboot boot twrp-3.7.0_9-0-fajita.img. The image is sent to the device and the device reboots, but, after rebooting, the same error (Attempted to kill init!) is shown. That always happens no matter what TWRP recovery image I try.

In recovery, I'm being told: "Can't load Android system. Your data may be corrupted. ...".

I'm trying to understand the meaning and impact of all that. As mentioned above, before all went pear shaped, I flashed the TWRP recovery image to boot. Slot b was active at the time, iirc. I assume that command would only affect the boot partition and maybe other partitions involved in booting, but shouldn't touch the system or data partitions. So, how do I proceed from here to get back to a functioning device or at least some recovery, that allows me to take a backup of the data partition? That would save me a lot of time even if I have to reset and start over in the end.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Penguinpee:
After a good night's sleep, I managed to pull myself out of this mess this morning.

I flashed the LineageOS boot.img to boot_b, the slot that was active when I previously attempted to flash TWRP. After that rebooted into recovery, which still complained about possible data corruption, hit the retry button and my phone booted back into the OS. 😅

I'm not sure which slot it is using now, but I'll leave that for another time to investigate. Gotta get other stuff done first. Thanks for looking over my shoulder @Timmmmaaahh!

I have Lineage installed on my OnePlus 6T but had to root it. I want to unroot it so I can use apps that won't run on a rooted device. I understand that I need to install TWRP recovery then use Magisk. I can Fastboot install TWRP but when I restart the phone in recovery it reverts to the previous recovery. Any idea why? Alternatively, can anyone give better instructions to unroot?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
Best way to unroot is to go stock(OOS) using MSM tool. However if you wanna stick to lineage os, then just remove magisk. However, apps now a days use advanced protocol and if you have TWRP & custom rom it can still detect as rooted. The only way to hide root and TWRP is through magisk hide, if the app still detect root with magisk then nothing can hide it.

The steps that are posted in the first post in the topic??
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
That doesn't answer the entire question. Did u tried older versions of the TWRP, not all versions might b compatible. I have moved backed to stock OOS on my fajita but the last version that worked on A11 is 3.6. Check if you can find unofficial versions of those posted in the thread if u r nt specific abt the latest and d greatest builds of TWRP.
