Many thanks, decryption fixed now. Tap to Wake and Double Tap to Wake also working fine with your recovery. Now all is perfect! :good:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] StykerB:
I'm going to ask a question and sorry if it has been asked elsewhere because I've been trying to search for answers and can't find any myself.

What steps do I need to take in order to prevent bootlooping after a previous Magisk install. Everything I've read says that flashing stock boot.img will take you back to stock but when I flash the stock boot.img provided in the OP then boot into twrp.img then flash the twrp installer then flash magisk I get a recovery bootloop. Also the recovery can no longer decrypt storage. I've tried rebooting during the various steps in the process but nothing seems to be working and I've even gone as far as to flash the stock rom via fastboot without clearing /data.

So that leads me to believe that /data has something in it keeping my phone from booting now. Is there something that everyone already knows and doesn't think to share that I need to do to /data in order to keep from bootlooping after previously using magisk?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
For all people is having problems with double tap to wake.

The installer doesn't flash a kernel so if you use it you will not lose the kernel otherwise if you flash the twrp.img in boot partition it's sure you will have some problems. In all cases today i will share a.new build with an updated kernel...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] efbill:
If my phone is power off , which buttons must I press to boot in twrp?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] baribalbear:
Yes, I was doing as recommended here - flashed img into the boot partition.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
No man, it is not reccomeded, the command i shared is "fastboot boot twrp.img" and it will only boot the twrp, you used "fastboot flash boot twrp.img" and this will delete your old kernel.

New 3.2.3-6 TWRP pubblished:

I have bluespark TWRP to on my OnePlus 6t... What steps should I take to install this new one. to avoid any issues I'd rather have a little bit of advice
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
You can also only flash the installer through sideload or otg. If you are unable to sideload the zip, you should use the full guide
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
So fastboot boot img> (sideload) installer> and >sideload magisk ?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
Nonononononononononononononono

The img must never be flashed but only booted.

If you need to boot the twrp you can use directly the img in the first post then you need to flash the installer zip, in sideload mode or from otg or manually.

If you have problems you can also use my tool, the twrp is always updated there:

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] suzook:
That doesn't actually answer my question. Obviously something still isn't right with twrp. I don't have a multi user account, I also don't have parallel apps. Still getting a 255 error. It's odd that some people can't restore data with no issues, and others have a problem. Wondering if it could just be an app twrp doesn't like?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
Man you are the only one with this problem, try to make a new backup using image option, for example "system_image" instead of "system", i think there is also a "vendor_image" and you can use instead of "vendor"

I don't know
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kgr:
If I flash the TWRP installer zip, I'm unable to boot into ROM. When I hit reboot system, it just boots back into TWRP. Maybe we're best to use temporary twrp until the decryption thing is sorted?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
If you flash the installer you need also to root your phone or it doesn't boot anymore
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kgr:
Ok so

- boot temp twrp img

- flash twrp installer zip from otg

- flash magisk 17.3 from otg

then twrp will stick and I can boot into oos also?

*edit* Confirm, above steps work. I can boot into twrp from oos, and I can boot into oos from twrp.

That's odd! The phone doesn't boot with TWRP installed unless it's rooted? Why's that?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] dreinulldrei:
Since you're compromising system integrity, Android won't boot. Now usually TWRP would patch system to avoid this, but since /data can't be properly decrypted that does not work. So you need to get another solution (e.g. Magisk) that will patch system (systemlessly) to allow Android to boot.

If this answers your question and you're a little more enlightened now, please don't hesitate to give me a thumbs up. ;)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Jason03c:
I am currently running it daily as a custom recovery , my steps were

- Fastboot flash temp recovery

-In recovery go to wipe and then format data (removed encryption temporarily)

Plug in device , mount, transfer over recovery zip and magisk 17.3 zip

-install recovery zip

+Install magisk 17.3

How does affect that Descrypt stuff?

Following the first post steps, would I have any trouble to flash Kernels / Magisk / Adaway..etc as always? Or after TWRP installation do I have to do anything else, like any time I acces to TWRP I cant have pin/password/fingerprint/pattern activated?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Twrp can't acces your internal storage ...

okay - after a lot of messing around today and after several softbricks I have worked out that it is indeed possible to decrypt using [MENTION=1030560]xXx[/MENTION] solution with the no verity patch from the op6 it does work and twrp is entirely usable but it f's with the locksettings some how meaning you are unable to set a lock pin to enable fingerprints to work because once set and then tried to use it always gives the infamous 'wrong pin' error !

I don't understand why people are trying exotic things mixing improbable tools together, none of them made for our phone.

- the solution will come, once proper blobs / sources will be available to compile a TWRP for our phone

- there is no custom ROM anyway: I don't need TWRP yet

Can't people just wait for example? Enjoy actually the phone for example instead of risking to really brick the phone for nothing (ok it's very hard to hard brick a OnePlus phone but God knows...). I love my new phone as is for now, I'm a long time ROM flasher but I'm not in a hurry at all

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
The backup method used, "system" and "vendor" are backupped file for file. "system_image" and "vendor_image" are backupped like image, so all the partition will be backup like it is, this is better and more safe but it needs of.more space.

Is it possible to permanently delete them?

Very strange. I flashed 3.2.3-5 last night before going to bed. This morning, I noticed my cpu was running at 1056 MHz all night while I slept. No deep sleep or anything. A reboot this morning seems to have stopped it. So, I'm not sure what caused it.

OnePlus OOS creates these 999 files and twrp cannot find tar policy. Even when they are deleted by the user, they are created again.

I believe it is actually based on a script file, not AROMA
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] :
Xxx isnt an aroma installer, its a normal updater script that instructs the mods to go where it tells it..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jl2222:
Negative. Aroma doesn't work for the OP6 TWRP either. The xXx No limits mod uses a profile script file that need to be edited in Notepad++ to define exactly what the user wants to install and not install. Pretty smart workaround in the meantime. I can confirm xXx No limits installed just fine and is working great so far on my OP6T!

I'll have to check out NoLimits. Not exactly sure what it will give me besides root and Magisk modules that I'm already using.

Does this mean you have to be running 9.0.6 first on your device prior to flashing this twrp? I am on 9.0.5 right now. Do I have to update to 9.0.6 first?

I would suggest that you do. Just in case there are any changes to the boot partition.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jl2222:
It adds a lot more than just magisk modules. Changes to the build.prop speed tweaks, battery tweaks, cell signal tweaks, disable Google wakelocks, animation speed etc. Also I ton of options to debloat your device with pre installed apps you don't use as well as a lot of modded apps like Gmail with exchange. It's an incredible mod. Highly recommend so far.

xXx No Limits is not technically a ROM. Its a bunch of tweaks & mods put together in one flashable zip for stock OOS that works on both the OP6 and OP6T. I dont think the inscreen fingerprint sensor would work with a OP6 rom but I have not tested this myself yet.

I was on lastest version of TWRP.

I made a backup and tried to restore it. It failed with 255 error during system restore .

Now I can't boot onto system cos its formated. What is worse after this error and rebooting or recovery all my files are encrypted again.

I tried procesure from OP , fastboot boot recovert.img , reboot to recovery but files were encrypted so I could flash twrp.zip. I sideloadeit it but it didn't help.

What I can do .?

PS D:\INSTALL\OnePlus 6T> fastboot boot "D:\INSTALL\OnePlus 6T\twrp-fajita-3.2.3-6.img"

downloading 'boot.img'...

If its a big update then yeah, but theyre so behind on the linux kernel, I highly doubt it for a while.. my kernel is 4.9.138 they are on 4.9.106.. once u boot twrp, flash the custom kernel of your choice, theres like 5 different ones, then flash twrp installer zip, then magisk.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] pyry666:

If we have latest twrp & custom kernel installed...

And we restore the stock kernel by flashing a patched boot img via kernel manager app ...twrp stays or we get stock recovery?....
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
Yes newer script only flash the kernel (zImage) so it still work, but generally it's always better flash before the kernel and then others kernel patches (like twrps, magisk and others)

no, you overwrite all the kernel so also the twrp
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
So the patched boot img its just stock kernel with root?

So we are loosing twrp..

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kirschdog1:
So is twrp working correctly now?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] mauronofrio:
Not really true, the boot.img is made of a ramdisk and a zImage, the real kernel is the zImage. The twrp installer will overwrite ramdisk and if you flash a modified kernel it should overwrite zImage. The problem is when you flash a modified kernel it overwrites all the partition.
