Is .27 retro compatible with Pie? If I flash it now as still on 9.0.17 waiting for a better version of Q.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Allen77777:
if you flash the installer it will install the correct twrp for your Android version. If you mean the IMG files than flash boot the one labeled Pie. So yes the .27 is compatible with Android 9

Woah have been away from XDA due to personal reasons since 10-15 days & damn [MENTION=4712355]mauronofrio[/MENTION]

you're on fire literally [emoji91]

You fixed the decryption issue even on Q! Cheers man!

So can anyone help me to update myself on the current situation?

I'm on Pie as of now with Magisk v19.3 & TWRP v3.3.1-7. Can I use the following steps to update to Q with working decryption & TWRP & Magisk?

1. Local Update to Q build.

2. Without rebooting, install TWRP 3.3.1-27 installer from Magisk Modules section.

3. Without rebooting, install Magisk v20.1 zip from Magisk Modules section.

Are these steps enough? Thanks in advance though :)

I'll try my best to catch up with all the posts I missed before before the next weekend [emoji14] thinking to get to Q again on the coming Saturday-Sunday. ;)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:

Titanium Backup is working a treat on Android 10 with this latest custom recovery and Magisk. The only thing that you may need to do in Titanium Backup > Preferences is to manually set your Titanium Backup folder path. Mine just accepted my previous Android 9 path.

I would suggest migrate over titanium. Works flawlessly.

Hi, I have Rom 9.0.1.7 + TWRP 3.2.3.2 + Magisk 20.1 and I want to update the twrp to the latest version 3.3.1-.27 without losing the root, how should I update it? Thank you
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] phaino00:
Reboot recovery > Flash TWRP 3.3.1.27 > reboot system > reboot recovery (ensure TWRP installed) > flash Magisk 20.1 > reboot system

All should be good and retain root status.

Hope it helps.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kevk60:
I rebooted to twrp and flashed the twrp 3.3.1-27 installer. Rebooted back into twrp from twrp to make sure it stuck. Flashed magisk 20.1 then rebooted system. Everything was good.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] uglavnom_bezopasni:
You complicate a lot. To update TWRP open magisk manager -> modules -> flash TWRP, back to magisk manager home install magisk (Direct install). No reboot necessary.

p.s. I'm against clean install, always dirty flash ;)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] the00guy:
Thanks for the simple explanation. It just occurred to me that we can therefore flash ROM updates with the built in OTA in Lineage and then reflash TWRP from Magisk (since the OTA preserves Magisk but replaces the recovery) without having to boot into fastboot with a computer to regain TWRP. Not sure how that happens if the boot.img is being replaced but this is awesome nonetheless!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] toolhas4degrees:
Bc the update is on the opposite slot and if you are booted and download an update when you are on slot a the update goes to slot b. Since you haven't rebooted yet, you are still using your current system and boot and have root access.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] henningsieh:
stucked in recovery bootloop

EDIT: Solved! TWRP 3.3.1.20 did it:

--- previous post ---

I can't help myself anymore. :( I always get stucked in the recovery bootloop without any chance to escape - only by a TOTAL RESET by FASTBOOT ROMS (https://xdaforums.com/oneplus-6t/how-to/rom-stock-fastboot-roms-oneplus-6t-t3862516). No matter what... always the same. I tried TWRPs -21 and -27 without success.

Everything goes well until I do the Cache and Data Wipe in the process to flash Bootleggers Rom for example... after that wipe I will never be able to leave recovery bootloop again. The most struggeling thing is the fact, that this Cache and Data Wipe even kills a fresh clean rooted and running OOS 9.0.17 - it leads to the recovery bootloop directly, no more booting into this OOS 9.0.17.

So now, when I'm stucked in recovery bootloop again (for the 8th time!!), even clean flashing of OOS 9.0.17 zip (or any other cutom ROM) does not help in any way - also no difference, if installing the TWRP installer zips or the "advanced ramdisk img" after ROM flashing. I do not want to flash the clean FASTBOOT ROM again and again... :eek:

Does anyone have an idea, where the problem or error on my side might be?? Please let me know!! Many thanks in advance, guys!

PS: it feels exactly like that:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] crosschris:
Bro i have had this problem so many times for past couple days..here is the problem its the new twrp builds recently..even backup is a problem an i had asked for help in here but got ignored however let me make your worries go away. Just flash the twrp build that ends with 20 reboot recovery and just hit format data type yes an reboot, it will boot well thats if you already flash a rom..if not just do what you normally do to flash a rom an format data then just keep on that twrp an flash all the roms you want normal bro.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] henningsieh:
Thanks, man!! :highfive:

I just tried that 20 min ago on my own - and TWRP 3.3.1.20 really works like a charm, without any problem!

Would be nice to know, which relating detail changed in v...-21? :confused:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] THERAJ12:
But then we need to flash old keymaster for OOS 10 or no?

---------- Post added at 05:41 PM ---------- Previous post was at 05:07 PM ----------

What error did you get in TWRP when it was in recovery bootloop? I've been getting a set_cache policy:failed ( or something like that)...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] wezmeister17:
Nope. Since version 3.3.1-24 decryption has been fixed and old keymaster is no longer needed
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] henningsieh:
Keymaster?? Not for me, because I'm afraid of using A10... I am on 9.0.17, as I wrote above. I did not understand anything about this creepy keymaster stuff. :cool:

And YES, I got the same error message after every failed system boot (but NOT on reboots to recovery). But I think this is not really the root cause, but could be an old code fragment of times when there was still a cache partition. Don't know... :confused:

---------- Post added at 07:36 PM ---------- Previous post was at 07:28 PM ----------

I would like to use it, but EVERY version starting from -21 and later is completely broken for me and orhers here (see above) - absolutely no chance to leave the recovery bootloop ever again.

I'm having not a single problem anymore since downgrading to v3.3.1-20.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] efex:
It just seems you have to do everything in reverse with the -21 + builds. First flash your rom. Then fastboot flash boot patched magisk boot. In macisk manager, flash recovery as a zip. Then everything works.

This is a bit backwards, but it's what we have for now. :)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] henningsieh:
Hey, many thanks for that!!

I prefer the -20 build instead of extracting and patching the boot partitions from each rom BEFORE I can flash it - that seems pretty uncomfortable to me. I absolutely need an unbreakable and stable TWRP as a permanent basis and starting point without needing a PC and fastboot every time.

Do you think we can expect the "good old way" in further releases?

btw: Thank you all for the delicious work here and for a kind and competent community! :highfive:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] THERAJ12:
I know but many people are stating the later versions from -21 onwards are faulty and I'm having alot of recovery bootloop issues so I may revert back to -20 and use the keymaster method...that worked perfect for me before I attempted to update and try a new ROM
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Pneuma1985:
Ok how do I get twrp flashed onto the latest oos build? I run fastboot boot twrp.img it pushes but nothing happens?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] iron@ss:
" fastboot flash boot ( filename).img" is the correct command.. to boot the recovery on Android 10
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Pneuma1985:
Ty sir gonna try that after work tonight...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] henningsieh:
That is not correct!

fastboot boot reovery.img

This is the right command!

Look at my screenshot and the OP:

There is no "flash" in this command!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
Starting with Q the command is "fastboot flash boot (recovery) img.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] henningsieh:
Wow - okay, thanks!

I think this difference is a very relevant information which should be placed in the manual and in the OP.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
Yeah I'm sure it will be eventually.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] osm0sis:
It's because OnePlus broke "fastboot boot", we're in the process of nagging them to fix it.

It's still the correct command to only temporarily boot an image, but it's just currently broken.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] McHoffi:
Today I made a backup within twrp with adb. Then I tried restoring it, didn't work, it got stuck at bluetooth for about an hour.

So now I tried extracting it with droid explorer and it asked for a password, entered mine and it didn't work. Then also tried to restore it with the phone booted, asking again for the password, but still doesn't work.

Does twrp have an automatic password for adb backup's?

Edit: Backup was made with A10 OB1, then I went back to stable OOS 9.0.17

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] DaOldMan:
Well, hard to believe luck has any part in this. I am a long time dev here and if the recovery was faulty i would expect to have bootfreezes like everyone else.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rowain:
Well good for you then man. There are not any bootfreezes though. Only boot-recovery loops. Either be it on pie, either on A10. I am a long time advanced user, had many devices, but i can't get past this problem. So i cant explain why on earth for some users it is buggy and for some not. 3.3.1-20 works perfectly, but the other 3 totally not.

So now that .28 is out and it seems generally more safe to upgrade to Android Q, what's the simplest method? Do we still have to mess about with pre-patched boot images or does .28 do away with that? I'm used to the 'classic' method of:

Flash new official OP6T rom

Flash TWRP installer

Flash Magisk

Reboot to recovery and Flash Magisk again

Reboot to System and done

Will that method work again now? If not, what is the workflow in the simplest terms like the bullet list above? Thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] izzibew26:

Hey fellas I got a quick question, I updated to Android 10 through the oxygen updater I made a backup of my stock 00 S 9 I wanted to preserve my data so I dirty flashed I was running Android pie on slot b and then when I did the update install the latest TWRP at the time 3.3.1.24 and the latest magisk manager I think it was version 20. I'm running on slainte now everything is running great it's lawless I love it. I have no issues I have plenty of sound mods and everything else plus battery life... I'm getting conflicting reports though, I didn't flash Android 10 two times to make sure it was on both slots. Is this an issue? Or can I just wait until the next update rolls out which should flash on slot B and upgrade the pie to Android 10 and if something goes wrong I will fall back to A partition.

Just curious on anybody's takes on this. Thanks
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
I dirty flashed A10 and did not flash to other slot... I've not had any issues either and I actually find A10 great myself. Since we're not experiencing any issues, I believe it's safe to say that having A10 on both slot at this point would be pointless.

I came from Nexus 6 and Nexus 6p. And I read 2 days of these guides before I did anything to my OnePlus I read all these horror stories. It was just the fact I have been out of the loop for a while and I had to learn the A/B partition system..But as soon as [MENTION=2055304]mauron[/MENTION]frio had the TWRP where we could just flash the installer then go to advanced and install recovery ramdisk and then the option to to write TWRP to A and B on the install section...these two massive improvements have no doubt kept me issue free.
