TWRP install impossible, phone doesn't make it past fastboot splash screen - OnePlus 6T Questions & Answers

Hey guys,
I just oem unlocked my new 6T and have access to the bootloader. As I try to install TWRP with
HTML:
fastboot boot imagename.img
my computer says that it pushes the image just fine, but my phone restarts and then never makes it past the fastboot splash screen instead of loading up TWRP.
I was following the fajita (6T) instructions from the lineage OS website.
The first time I did it it worked, but following the instructions on installing lineage and telling me to wipe and format data, both the recovery seems to be gone and i cannot fastboot boot into TWRP.
Can you help?

Seems the same with what i experienced. Have you tried installing a fastboot rom? I had my oneplus 6t bootlooped into fastboot mode even if i try to turn it off, it just boots back automatically to fastboot mode. Last resort was to flash a fastboot rom. That worked for me.

What TWRP version are you trying to install?

I tried 3.3.1.1. and 3.2.3.0.

What you are describing, I'm going to assume you are trying to install Lineage 17. You can't install TWRP if you are going Android 10, at least that's the conclusion I've come to at this point in time. It will fail to boot or end up in crash dump mode every time you try and enter recovery if you are on a custom ROM. If you are on Android 9, it's not an issue. I believe it's OK stock as well, but I don't know haven't tried, haven't been stock in a long time.
For LOS 17, only boot the TWRP image, never boot to recovery, never run the TWRP installer. You will likely still have to format data.
I have a post here, from when I had a similar issue. (instructions)
You'll notice the OmniRom instructions don't mention installing TWRP, only booting it.
Once I was in your spot, I always went back to stock using the fastboot ROM, installed TWRP, updated (still using TWRP), then started over with my install.

Well no, i was actually trying to install Lineage 16, which is Android 9 I believe.
The problem for me is that I do not get to the point where TWRP opens after "fastboot boot"ing it. So I understand, I should use a fastboot stock ROM? Is there such a thing? Where would I find it? Or would it be an OnePlus Oxygen ROM that I can fastboot?

Quickest way to start over:
To get back straight your gonna need to access a Windows PC, and run the MSM tool. Make sure you install both OnePlus and Qualcomm drivers. ( Don't wait for Windows, just pre install the drivers) here are some links. Not my work. Please be sure to thank the developers for creating and hosting these tools ?

Were you on Android 10 before (OOS)? That will do that. LOS 16 is Android 9 and should have no problems installing TWRP or booting to it.. For LOS 16 I'd go back to 9.0.17, then install LOS 6T.
I posted these LOS install instructions a long time ago for another user.
Remember the MSM Tool will relock your bootloader so if something goes wrong the MSM Tool is your only choice. That is why it is always the last thing I resort to.
Thread to get Fastboot stock Roms if you want to try that route first.

Hey guys,
thank you so much for all your help. I've managed to use mauronofrios workaround here on xda to put my phone in a 9.0.17 state again (no idea what i had originally), and this way i could fastboot the twrp image again. so that worked fine, but so far flashing lineage hasnt worked, for whatever reason it seems to boot into a lineageos kind of recovery only (which i didnt even know existed).
So i guess in terms of this thread the problem is solved. Thank you again!

Did you see my Lineage install instructions above? LOS installs its on Recovery when you flash the ROM. When om Android 9, boot TWRP, flash the TWRP installer, reboot to Recovery, install LOS 16, flash the TWRP installer again (replaces the LOS recovery that was installed), reboot to Recovery, install gapps / magisk if desired, reboot.
Read my instructions post though, the first time install is different, as you need LOS on both slots. Updating is different as well, its much easier.
It should go smoothly.

Do I need to be on Android 9 Stock when I start that process? What I did was boot into TWRP, flash TWRP installer, reboot into recovery, then format and wipe ALL partitions (except USB), then reboot into recovery again and then flash LOS, flash TWRP, reboot into recovery, flash LOS, flash TWRP, reboot system. Still no luck...

Wiping, Dalvik / ART, System, and Vendor is generally a bad idea. You can do them in certain situations, this isn't one of those situations you should be wiping those though. Factory reset, means the slider on the main page of the wipe screen that says swipe to factory reset, format data is the button that says format data. Don't do anything extra. If you did, yeah I would go back to 9.0.17 using the fastboot rom again, that will put everything back on both slots.

like OhioYJ stated, don't use advanced wipe. re-run the msm tool. Then follow his instuctions. You shouldn't need to preform any manual data wiping. The process of flashing will do everything required. looks like you're almost there

Thanks guys. I will try it out and let you know.
Edit: So I finally managed to properly install LOS - OhioYJ, your instructions worked! I installed 9.0.17 and went from there without wiping any additional partitions.
One questions remains: in your instructions you mention that after installing LOS once, you can update LOS as normal and you mention doing it via the recovery with flashing TWRP or GAPPS later again. Is it possible to do the update via the normal update function of LOS as well? Or will that overwrite TWRP?
You guys are awesome. Thank you so much for your help!

I seem to be stuck on the fastboot screen as well. Being on a MAC, anytime i try to do something in fastboot it goes straight back to the fastboot screen. I Thought I was on Android 10.0 trying to install recovery for that lead to bootloop of fastboot, tried using the Pie recovery and same thing. I am open to suggestions.
Thanks.

Yeah it starting to seem like it maybe isolated to Lineage. You cant install TWRP with LOS 17. Someone else mentioned in the Omni thread that it worked. This thread is about Lineage, but that should be clarified, or clearer.

TWRP Not working

Hi, I have a essential phone running Oreo 8.1, just recently I have rooted the phone with magisk v16 an twrp 3.2.1, I successfully flashed it with twrp but after the flash whenever I want to get into twrp it just freezes up on the mount data screen and I have to force reboot it, does anyone know a solution to this problem
Make sure you're following the exact steps from this post. Every step is crucial (except #3, because you have to disable your screen lock before booting twrp.
You shouldn't have to manually mount anything in TWRP either. The magisk installer might give you an error about mounting system but it doesn't seem to make any difference.

You cannot have TWRP installed with 8.x.
TWRP is not compatible.
You must flash the original boot image, then install magisk.
TWRP cannot remain.
You will boot loop.
Please read the instructions on rooting carefully.
Ok thank you

Because the partition layout of the Essential does not have a recovery partition.
Recovery is contained in the boot image.
So to have TWRP resident/permanent, the boot image must be patched.
It has been done for 7.x, but sense 8.x is still beta, there is no official TWRP for Oreo.
Once Oreo is final, I expect we will get a TWRP that works.
The current limitation, means you can't flash without a computer handy.

Can't get custom ROM installed

I'm having a very difficult time getting this phone setup. I can get very, very close... but then it starts boot looping into recovery.
So starting at the beginning, here is what I did:
- Booted up phone, make sure it works and connects to wifi (I find out later that it got encrypted, even though I didn't set a PIN).
- Inside the OS on first boot, I install and use the official bootloader unlock APK from Asus.
- Rebooted into the bootloader and fastboot flashed TWRP.
- Rebooted into TWRP and flashed the Oreo modem, current unofficial Carbon OS 6.1, nano gapps, and magisk 16.6.
- Rebooted and the Carbon ROM logo comes up. It works for about 2-3 minutes, then reboots.
- After many attempts to decrypt (and a lot of help from the forum), I successfully restore the phone to "WW_ZE552KL_14.2020.1712.85_M3.10.47.15_Phone-user.raw.zip" with the Asus tool.
- Phone is fixed and booting again to the OS, but I'm back to square one.
Second attempt:
- Thinking I need to flash the raw Oreo ROM (instead of just the Oreo modem), I use the Asus tool to flash "WW_ZE552KL_15.0410.1803.55_M3.10.47.19_Phone-user.raw.zip"
- The phone works fine and is now an Oreo ROM with an Oreo modem
- It's still unlocked, so I rebooted into the bootloader and fastboot flashed TWRP.
- Rebooted into TWRP and flashed the current unofficial Carbon OS 6.1, nano gapps, and magisk 16.6.
- Rebooted and the Carbon ROM logo comes up. It works for about 2-3 minutes, then reboots.
- After the reboot, it goes to TWRP... whether I just let it boot on its own, or press power when it says: Start - Continue to boot >
What am I doing wrong?
You're having a rough go at this one eh.
I know we talked about this before, but did you try a factory reset and wiping cache/dalvik before rebooting?
Yes. As we discussed before, you can't wipe cache from TWRP. So I'd wipe dalvik from TWRP, then reboot to the bootloader to do a "fastboot format cache".
I'm going to try a different ROM later this afternoon. Maybe that will make a difference.

Hello! I've been able to boot any ROM by:
1. flashing TWRP
2. rebooting to recovery
3. installing the ROM zip
4. rebooting to bootloader

But when I restart the phone, it always boots to recovery(TWRP), so I have to repeat steps 4 and 5 to boot the ROM, which is
Could you try and tell me if it works for you too?
I'm gonna take a moment to read about the boot process in depth, as it seems there is no straightforward solution to this out there.

1) Flash Oreo RAW (can be downloaded from @Saktis_STi' s unlocking thread.
2) Boot till system
3) Flash TWRP
4) Flash ROM, Magisk, GApps
5) Reboot
The reason why it reboots to TWRP is because of 'encryption' thingy.

many many thanks! I was able to get Ressurection Remix working by now
your steps were right, and I will detail them better to tell how I made it work for others reading this thread:
1) Flash Oreo RAW
1.1 - @Saktis_STi's thread is a bit outdated. I downloaded the newest firmware from Asus website.
1.2 - I also had to find a recent recovery.img, which I think I got it from here https://forum.xda-developers.com/zenfone-3/how-to/original-recovery-img-boot-img-zenfone-t3572188
1.3 - I used the stock recovery's adb sideload to flash the stock ROM
2) Flash TWRP - all good here
3) Flash ROM, Magisk, GApps
3.1 - I wiped system, data, cache and dalvik.
3.2 - I flashed RR ROM, GApps and Magisk (EDIT 2: install all three before the first custom ROM boot, or GApps won't work)
3.3 - Performed a Factory Reset
4) REBOOTED TO GLORY!
For what it seems, the stock ROM encryption that is performed on the stock's first boot was the enemy.
Now one last thing... In Security -> Encription, my device is NOT encrypted.
Do I run the risk of ruining everything if I encrypt it?
EDIT: No, it didn't break, working fine

Why can't i use any rome except OmniROM? The Phone does not boot at all.

Hi there folks!
Sorry if i open a thread, probably you've discussed somewhere before about this problem that i'm experiencing.
My OnePlus 5 basically works only with omniROM, it doesn't boot at all when i try to install another one.
I tried with this:
https://forum.xda-developers.com/oneplus-6/development/rom-aospextended-rom-v5-7-t3825642
and this one:
https://forum.xda-developers.com/oneplus-5/development/rom-crdroid-android-5-0-t3836886
I followed every step (About CRAndroid), radio firmware 5.1.5 + TWRP 3.2.3 + Gapps + Magisk 17.1 and No Verity v3 (First try without noverity, second using it)
and i followed also every step neeeded in AOSPExtended rom.
When i try to boot the phone, after the OnePlus logo, nothing happens. The phone reboots in recovery mode, that's it.
If i repeat the same steps with OmniROM it works all fine, except Magisk. If i flash Magisk on the Omni it doesn't boot, if i flash SU it works.
Could it be something related to the encryption/Decription of the device?
When i go into TWRP it doesn't ask me for a pattern or a code. It should be decrypted, right? (i'm a bit confused about that).
I purchased the phone on Gearbest, could it be a particular version of the phone that doesn't allow me to work properly with roms?
Help
did you tried old stock ROMs, 4.* versions ? then 5.0.0 and then the others
Sometimes the partitions need to be wiped. Try a fastboot format userdata; fastboot format system.

You....you're a good guy.
I did the command you said, then i booted into TWRP, flashed AospExtended, Gapps Pico and Magisk 17.1 - after reboot it has been stuck @ 1+ logo, then it rebooted again (as always when it doesn't work) and i said "ok here we go again in the TWRP-loop" and INSTEAD it booted rom! Yes!

After update to V11.0.4.0.QFJEUXM TWRP no longer available

Hi Guys,
yesterday the new update came out, great.
I of course immediately pulled the zip (source) and installed it with TWRP (source).
So far no problems.
After a while I realized that I no longer had root because the apps stopped working.
When I wanted to boot into the TWRP to reinstall Magisk, I unfortunately found that it was no longer available, but only stock recovery.
Well, I thought to myself and tried to reinstall TWRP (method-twrp-3.3.1-2-davinci-fix), which was fatal, because my cell phone only booted into the Fastboot.
Then I got my cell phone, set up again with the Fastboot method.
Now I'm back to 11.0.4.0 but unfortunately without TWRP and root.
Can someone please describe how I can get TWRP and root again on Android 10?
I am thankful for every help !!!
Same thing happening to me, no matter what I do, stock recovery keeps overwriting TWRP
Oh dear, that doesn't sound good.
I hope there will be a solution to the problem soon.
I don't want to do without TWRP and root.
I wanted to try it according to these instructions "https://miui.blog/redmi-k20/twrp-mi-9t-redmi-k20-vbmeta-mauronofrio/". But don't trust me, I'm afraid that it won't work and I can start all over again.
Flash official TWRP this morning with fastboot commands without problem.
1. reboot in fastboot mode
2. Flash recovery with this command "fastboot flash recovery yourrecovery.img"
3. Reboot in recovery with this command "fastboot boot yourrecovery.img"
Any problems here.
The fact that twrp is lost when flashing official rom (even thought twrp itself) is normal. You just have to reboot into bootloader and flash twrp again and it will be back.
Your problem here is that you are using an old and unofficial twrp build, that has problems on newer roms. Flash official twrp and you'll be fine

Check it out...
I finally got it
I did the following.
"V11.0.4.0.QFJEUXM" flashed in the TWRP and booted into the system, TWRP will be overwritten.
Now flashed TWRP "twrp-3.3.1-0-davinci.img" in Fastboot and booted into Recovery (TWRP).
To be on the safe side, I had the cell phone booted again into the TWRP in the TWRP.
Then I flashed Magisk "Magisk-v20.3.zip".
Booted cell phone into the system and everything works.

To install TWRP, is it neccesary to wipe Data (or something else)?
And if Data must be wiped, does it mean that Data will no more be encrypted as originally by MIUI?
I have 11.0.4.0, rooted by Magisk (Magisk installed simply by patching and flashing boot.img, did not need TWRP for, did not wipe Data, etc) and I possibly want to have TWRP but don't want to loose encryption of Data, Widewine L1 and so

You don't need to wipe anything to install a custom Recovery (like TWRP).
TWRP can handle ROM encryption, you just need to install a correct TWRP, and version, for your current MIUI / Android version.
A custom Recovery doesn't change Widevine level.
And TWRP is useful in case of bootloop (because of an installed Magisk module, by example) or if you want to easily reinstall Magisk after ROM update.

Ok thanks, so starting from v11.0.4.0 QFJEUXM, rooted by Magisk (did not wipe Data or so, just patched and flashed boot img), is it ok just to flash (from Fastboot) twrp-3.3.1-0-davinci.img, downloaded from the official site https://twrp.me/davinci/twrp-3.3.1-0-davinci.img
Maybe I could test first by
fastboot boot twrp-3.3.1-0-davinci.img

Something is fishy. IMO, if that official TWRP is really ok for 11.0.4.0, then it should correctly boot by:
fastboot boot twrp-3.3.1-0-davinci.img
But phone rebooted into the dark.
TG, I didn't really flash with, so by long pressing Pow it rebooted to system.
Tried again, no avail
Edit:
Tried the same fastboot boot with
twrp-3.3.1-12-davinci-mauronofrio.img and also OrangeFox-R10.1_1-Stable-davinci.img (obtained by unzipping OrangeFox), but it also reboots to dark and I have to long press Pow to reboot to system

When I wanted to boot into the TWRP to reinstall Magisk, I unfortunately found that it was no longer available, but only stock recovery.
Well, I thought to myself and tried to reinstall TWRP (method-twrp-3.3.1-2-davinci-fix), which was fatal, because my cell phone only booted into the Fastboot.
Then I got my cell phone, set up again with the Fastboot method.
Now I'm back to 11.0.4.0 but unfortunately without TWRP and root.
Can someone please describe how I can get TWRP and root again on Android 10?
I am thankful for every help !!!

You can install twrp by All In One tool
You can find its thread here itself
I took the official TWRP. " Link "
Flashed in fastboat and then booted the phone with a key combination in TWRP.
With the Fastboot command it didn't work for me either, the cell phone remained black ...

[Solved] It's impossible to install LineageOS on my 6T.

Hello everybody.
Twice I tried to install LineageOS 18 on my 6T, equipped with latest OxygenOS/Android 11 version, without any success despite having followed several tutorials on Youtube and on websites.
Two days ago I unlocked the bootloader, I restarted the phone from the PC in Fastboot mode and I tried to install the TWRP recovery, always getting an error and when it seemed that I had succeeded the phone restarted showing the message "Qualcomm Crashdump" and the phone was dead.
Fortunately, a Wipe Data from the Recovery allowed me to get the 6T working again.
Last night I tried again by installing the LineageOS recovery first, I restarted the phone and I realized that it was in bootloop.
At this point I could only restart it in Recovery or Fastboot mode, without being able to start the 6T correctly; not even a wipe data helped me.
At that point I used the MSM download Tool, with which I was able to reinstall OxygenOS v9.xx and restart the 6T, then updating it to OxygenOS 11.
The drawback now is that when I turn on the phone it takes over a minute to boot (the two dots around the OnePlus symbol make a good 37 laps, after which the phone starts up and works perfectly).
How can I fix this slow boot problem?
And why has it become so difficult to install a custom ROM on the 6T? It occurs to me that OnePlus has deliberately complicated things to hinder modding.

Did you get twrp installed? Wipe data by typing yes after flashing?

You can follow this. If you want to install lineage os and want Google service make sure follow the "non gapp version" under installation method.

Thanks for replies.
I must add this point: my 6T has OxygenOS v11.1.1.1; maybe this the reason of the problem? Maybe OnePlus did something that screws any modding attempt?
I simply followed the instructions found on YouTube, in the LineageOS' Fajita page and installed TWRP, but my 6T went in "Qualcomm Crashdump" and TWRP was not working → phone bricked.
Then I've tried installing, in the same way via ADB and Fastoot commands the Lineage Recovery, that has worked but when I tried to boot system, keeping OxygenOS, the phone went in bootloop.
So where is the error/fault?
Please, help me with a step-by-step tutorial that lead me to successfully install TWRP and LineageOS on my 6T.

OnePlus definitely didn't do anything to make it harder. You need to fastboot boot twrp.img then flash the twrp installer zip. I'll attach both In next post. Reboot to recovery. Then install OOS, twrp installer, reboot to recovery. Install oos again, twrp installer again, reboot to recovery. Now install lineage, twrp installer, reboot to recovery. Install lineage again, twrp installer again, reboot to recovery. Factory reset and wipe data by typing yes. Boot to system
The img is for fastboot boot
The zip is for installing in twrp
Thanks for your reply.
I'm still wondering how to speed up the boot.

If everything is installed correctly it won't take long to boot

There is clearly something wrong, as my 6T's boot is slow.
Furthermore, the Recovery of the previous message is the one I downloaded three days ago and that made me go to the 6T in Qualcomm Crashdump.
I repeat my request: where can I find a safe and updated guide that explains how to install LineageOS without risk?
If you can't fastboot boot into that twrp on a11 without crash dumping there is something really wrong

You sure you didn't try 3.6.0_9?
Clearing your cache might help with current boot. But once you install a new os everything will run smooth like it should
Thank you for the advice.
1) I've downloaded "twrp-3.6.0_9-0-fajita.img" and tried to install it several times, getting errors and then bricking my phone.
2) I have already cleared the cache several times from Recovery, without anything having changed; the two white dots on the boot screen continue to rotate 37 times around the red dot before the phone starts up and then works perfectly.
It occurred to me that the MSM Download Tool program uses a decrypted image of the original firmware; could this possibly be the cause of the long boot?

That twrp version always will crash dump on a11. Use the one I sent
I followed these steps:
after having managed to make MSM Download Tool detect the phone in EDL mode, I proceeded by reinstalling OOS v9.0.13, after which I reconfigured the phone and restored the apps backup stored in my Google account.
Later, I don't remember the details well, I received the update notification for OOS v10 and later for OOs v11.1.2.2.
I don't remember exactly where the boot started to stretch, however this is more or less the process I followed to bring my 6T back to life.

Are you sure that this TWRP will work without problems?
I've tried also with Lineage Recovery for Fajita, resulting with the 6T in bootloop :-(

I promise it works. I do t know what happened with your previous updating and msm tool but something sounds messed up. Just get twrp running and ease all your problems. Clean flashing and getting everything fresh

Keep your finger crossed...
Another question: assuming I can install TWRP and make it working, LineageOS image must be copied in the 6T's internal SD and proceeding to install from TWRP?

Or you could use USB OTG. Or a PC and use adb sideload
