My OP 7 PRO(GM21AA) is being completely stuck at Fastboot.

Hey,
It's been always a huge headache since when the Android 10 beta and stables updates are out to root and install twrp. I've tried almost every way possible but every-time, end up being stuck at TWRP or being half way rooted. This time I've tried doing that again :
* I was at OxygenOs Android 10 stable version,
* My bootloader was unlocked as well as OEM unlocking and usb debugging was on,
* I turned my phone into fastboot, and flash the twrp image as:
fastboot flash boot file.img
Then after my phone booted into TWRP since once or twice showing that 0mb internal storage, I flashed the Magisk.zip from adb command, and rebooted it.
Since then, my phone is completely stucked at fastboot, I've tried and followed almost every xda suggestion and everything, I've tried flashing flash.bat file, I've tried flashing stock recovery, In fact I've tried flashing complete fastboot Rom (with all in one app)and it everytime boots me into Fatboot.
Please, help me out guys. I'm stressed out of this problem since yesterday's night.
Let me know your suggestions.

Maybe THIS can help you?

Actually this thread helped me just now in the same situation:
https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
That thread Jonsat mentioned didn't help me either, at all. Its not very clear that thread, telling in the thread to unbrick a OP7 to look at the thread of the OP6, there send them to OP5 and so on, eventually having to use a short written manual for the OP3 which mentions different versions and so on, its not the best for inexperienced people like me, it just send me on a wild chase downloading drivers and other things that eventually didnt work at all. Maybe I will try to rewrite it, as soon as I have enough experience to do so, i own this device for just a week.

Next time, read before you peform the install steps. It's nowhere like the older devices due to the A/B Recovery.
1. Use MSM Downloader to put you back to stock.
2. Upgrade to Android 10
3. Factory Reset to Clean out your phone (don't forget to unlock bootloader)
4. Initialize phone
5. Boot twrp (specific to Android Q + OP7 Pro)
6. Install TWRP and Magisk from TWRP
7. reboot and enjoy your rooted phone

What is MSM download tool? I'm going to try using All in One.
On searching for MSM tool, I found https://www.techoxygen.com/msm-download-tool/ is that correct?
Scratch this, MSMdownload is part of zip, I'll read through https://forum.xda-developers.com/showpost.php?p=79972789&postcount=50 and see how it goes

Can´t boot to recovery. Always landing in QUALCOMM CrashDump Mode

Like the title says, I can´t boot to recovery (Oneplus one). If I try to boot to recovery, I´m ending in the Qualcomm CrashDump Mode.
I have a Oneplus 7 Pro with Stable 10.0 BA FW.
Rooted with Magisk (Patched Boot.img) Is this causing the problem?
After pressing Vol+ and powerbutton, the devices boots normally.
Thanks in advance.

I had the same issue this morning when trying to update to 10.0.1. Just boot to bootloader and boot twrp then install 10.

I think is the magisk update (magisk 20.0) that causes this, because it's happening to me in the beta 3 and before I updated magisk it was working fine with the beta 2

I have no issues with magisk or twrp.
It might be the way you are installing ota or rom.
Might be model specific not sure as I don't know what model you are on. Mine is GM1915.

I'm talking about the official recovery

GM21AA, exactly the same situation (from 10 stable to 10.0.1 and magisk from 19.4 beta to 20) and the stock recovery bump into Qualcomm Crashdump problem here, system bootup normal as well as bootloader.
Troubleshooting:
1. Local update twice, install magisk at inactive slot OTA before reboot, for Android 10's A/B partitions machinasm , try let magisk patch both boot.img. Same...
2. Local update and reboot, lost root but stock recovery work, Fastboot boot twrp.img (latest, not flash, cause I don't need the permanent twrp)->twrp install magisk, reboot system, then, again, same problem.
Todo:
Magisk manager or twrp uninstall magisk, but if it's fail maybe ended up to bootloop, scary.
May try to install back old 19.4 magisk.zip via twrp, it's working in 10.0.0
Anyone with the same problem have any idea?

Thats the exact same error I ran into.
But as mentioned earlier, I never had TWRP on my OP7P. I flashed the patched boot.img via adb and I´m still on 10.0 BA Firmware.
I thought TWRP dosn´t work on Android Q (I´m coming from an Pixel3 and there it won´t work) So maybe I will give TWRP a try tomorrow. Are there different versions or is the official one the best?

The recovery here is the one to use.

Be sure to read through

So thanks erveryone who helped.
I now have TWRP running as recovery. So there is no need for official recovery. (and no Qualcomm CrashDump Mode)

Had this happen to me earlier this week. Just ended up using the MSM tool and restoring shipping firmware. You can look for the unbricking thread here for more info on that.

Yea, this just happened to me. Updated Magisk, Updated to 10.0.1 from 10.0. Booted fine.
Re-installed a few magisk modules (didn't just re check the modules, but reinstalled each)
Now OS won't boot, and recovery goes to Crash Dump. Would be ok if OS wouldn't bootloop and I could get to OS.
Oh, and my ADB now is an unauthorized device while its in bootloop mode
EDIT:
phew. Tried to hold volume up+dn rather than up or dn, got into bootloader. Able to fastboot boot TWRP and then delete problematic RIRU magisk modules. All is well in the world now...

I don't get it why it have to be so hard.
I'm constantly soft bricking/ bootlooping this phone when trying to do simple things such flashing magisk and twrp. I remember it being so much easier with my Poco F1, never got close to bricking it.
Now every little mistake ends with a bricked phone and 5 hours on the internet trying to understand why

Same issue here and no TWRP installed.
I did ADB REBOOT FASTBOOT and was able to install the twrp image by FASTBOOT BOOT twrp-3.3.1-70-guacamole-unified-Q-mauronofrio.img
Going to try and remove Magisk and see if I can salvage my data and then re-install Magisk afterwards.
Ok...got back into the system by flashing the Magisk Uninstaller in TWRP that is here: https://magiskroot.net/md/Magisk_Manager_for_Recovery_Mode_(mm)-2019.4.4.zip
Went to advanced in TWRP, then to terminal, then typed mm.
Typed in C for Core only to load into system without Magisk. Deleted my Magisk modules that may have interfered with it (I had an older version of No Limit that I should have updated prior. After removing and rebooting back into system, all is fine now.

Yea man, things are hinkey this update.
My big problem was i had twrp but it got wiped i guess (could no longer access) and couldn't access adb nor fastboot. But finally got into bootloader (cmd fastboot) so was able to fix.
Easier solution than installing Magisk uninstaller (presuming one has twrp installed, which would be the case if able to flash Magisk uninstaller) is go to TWRP>advanced>file manager and navigate data/adb/modules and delete from there

DO you guys know if there is an updated magisk being developed or what is the way to fix it? Uninstall magisk via TWRP (since I can temporarily install and get into TWRP using the all in one tool by the TWRP developer). Then install TWRP and then Install Magisk ?

Stuck in CrashDump Mode

I just purchased a new OnePlus 7 Pro yesterday and immediately set about rooting it. This is the process I followed:
fastboot oem unlock
fastboot flash boot twrp-3.3.1-4-guacamole.img
TWRP: Install > Select Storage > Internal Storage > Magisk-v20.3.zip
TWRP: Wipe > Format Data
I rebooted and was confused when I wasn't rooted. It seemed the last step had undone my root, so I went back into TWRP and installed Magisk again this time without formatting data. When I rebooted I had root and all was well.
However, there was an OEM update available that warned me it would remove root if I installed it. I found this guide to install an OEM update without losing root, which basically says to download the update via Oxygen Updater and then install it from TWRP. On step 6 is says to select the "Inject TWRP after install" option, but this didn't exist in my TWRP. I went ahead without it, thinking maybe it was enabled by default in my newer version of TWRP. The installation seemed to go without a hitch, but when I rebooted after I was stuck in fastboot. I couldn't boot my phone, nor could I get back into TWRP or regular recovery, only fastboot.
I tried flashing TWRP again using fastboot, but to no avail. I also tried running fastboot -w, but was still stuck in fastboot. I did some more research and found this comment which made it seem like all I had to do was download 10.0-GM21AA-OnePlus7ProOxygen_21.O.20_OTA_020_all_1909172051_db7a3f61-FASTBOOT from here and then run flash-all.bat. Once I did so I ended up stuck on the following screen:
Code:
QUALCOMM CrashDump Mode
--------------------------
dm-verify device corrupted Force Dump
kernel_restart
I can't seem to do anything at all with my device; not even turn it off. I tried holding the power button down for nearly a minute and no response from the phone. Is there any hope at all for my phone or have I properly destroyed it?

https://forum.xda-developers.com/oneplus-7-pro/help/mistake-kernel-error-t4029743
Same thing happened to me and I searched around a bit and found resolution. You can try what I did or try msm tool but search first as crashdump error is becoming common issue it seems
I held both volume buttons until restart and let go of one of them to get into recovery and then boot to boot loader if needed

Thank you so much! I thought I'd corrupted fastboot and permanently bricked the phone.
Once I was in fastboot I used tool all in one to flash 9.5.13-GM21AA-OnePlus7ProOxygen_21.O.16_OTA_016_all_1908281716_b2bb5-FASTBOOT.zip onto my phone by picking Flash Factory Images, and now it's back up and running.

This was the magic trick I needed to know. Holding both volume buttons didn't quite work for me. I held them both down for over a minute and nothing happened. Then I tried holding down the power button and that seemed to work after several seconds. I didn't hold down volume down quickly enough the first time, so I had to do it again. I held both volume buttons and the power button for over a minute, but again, nothing. I tried a couple more times and got it to work. Haven't been able to figure out exactly what causes it to exit the CrashDump mode, but the volume buttons together seems to be the important part.

This time I tried doing the OEM updates first, thinking that attempting to install them manually is what caused my problem. First I installed the 10.0.3.GM21AA update, then after rebooting I installed the 10.3.0.GM21AA update. At this point it said my system was up to date, so I want ahead and booted into fastboot and ran fastboot flash boot twrp-3.3.1-4-guacamole.img. No errors, but no TWRP either. My phone was stuck in fastboot again.
Is it necessary to stick with 9.5.13 if I want root? Is there some way to get TWRP to work with 10?

Just use tool to flash 9 then after first boot fasboot flash whatever 10 build you can find. Then after first boot of 10 try boot twrp and install twrp.
Honestly I just used the tool to root and flash recovery. There is a button for that and just pick your files. Good luck

You need to use a more recent versions of TWRP with Android 10. Current unofficial version -74 should work. So in your current condition, you should be able to simply boot TWRP (using the correct version), flash TWRP installer zip (if you want TWRP installed), flash Magisk (current version is 20.3) and reboot and you should have root again.
Easiest way I've found to install the OTA updates, is to simply install the update through the phone settings, do NOT reboot immediately after the update, go into Magisk Manager, flash TWRP installer zip as if it were a Magisk module (optional, if you want TWRP installed), then install Magisk picking the option "Install to inactive slot (after OTA)". Than just reboot, and you should be updated and with root.

Ah, I was using the Official TWRP App to get the images so I was under the impression that twrp-3.3.1-4-guacamole.img was the latest. I assume you're saying I should use TWRP 3.3.1-74 Unified Unofficial Q by mauronofrio from over here instead.

This is good to know. Thanks.

Just to follow up, I applied the available OTAs through the phone settings (up to bulid 10.3.0.GM21AA) and then followed the More articulated but fully functional instructions to install TWRP 3.3.1-74 Unified Unofficial Q. Everything went well and I'm now up to date and rooted. Thanks again to both of you!

That is the correct TWRP to use ("Unofficial" version -74), as it appears you have already determined.
I don't know why the "official" versions have fallen so far behind. It's been months stuck on version -4, so it seems that they have stopped going "official" for some reason. No matter, the unofficial versions are working fine (and in fact required for Android 10 as you now know), so the "official" tag seems like a technicality.

On these OnePlus phones I don't know why they love Qualcomm Crashdump mode. I fixed it sort of like you, but this worked 100%. You hold all 3 buttons (power, vol up, vol down) and you bypass the crashdump (takes several seconds 5 maybe 10), just quickly let go so you'll be in fastboot mode and can work your magic to fix the damn thing....
I even contacted OnePlus on an 8 they had no idea what to do...

Fastboot flash boot recovery.img <-- bad idea
Fastboot boot recovery.img <-- provit

I might have hard bricked my op7pro

So this happened a couple minutes ago, i prepared my op7pro to update to the latest version available.
Here are the steps i took:
- Made a backup of the apps via Titanium Backup
- Removed all Magisk modules
- Downloaded the latest firmware via Oxygen Updater
- Moved it to root directory
- Checked the firmware via settings -> System Updates
- DID NOT INSTALL IT
- Went back to Masigk, installed the module "TWRP A/B Retention Script ", did not reboot
- Magisk again -> Install Magisk (install to inactive slot)
- Rebooted, and it stuck on the loading screen, i waited half an hour but kept stuck. So i decided to to reboot using the POWER BUTTON + ARROW UP Combination.
- Accessed TWRP via POWER BUTTON + ARROW DOWN Combination.
And here, is when i panicked. NO ACCESS TO THE INTERNAL STORAGE. I don't care about any data i have, i make backups, but i might **** my pants if i bricked the internal storage partition or something else. Right now i'm downloading the Fastboot roms, and the MSM Guac for All.
Which version of fastboot rom should i choose?
Additional Information:
- TWRP : 3.4.0.0 by mauronofrio
- Oneplus 7 pro EUROPE
- Bootloader Unlocked
EDIT: I was able to fix the partition using TWRP WIPE Data -> Format Data -> Reboot to Recovery
EDIT2: Flashed the firmware that i downloaded via the official Oneplus website via TWRP and it's working again.
I wouldn't have made the post if it wasn't for the partition problem, i've been flashing roms since the G1, this is embarassing. Anyways this issue has been SOLVED.

I see the mistakes you made,
You need to remove module then install OOS
Don't reboot, install retention then install magisk to inactive slot. Reboot.

Yes, thanks for taking the time, i forgot to install OOS that's what happened. I managed to fix it now. Thanks again

So you know this would be considered soft brick. Hard brick is no life no edl without test points. Just for clarification on the future

TWRP can't decrypt + Fastboot loop

Unsure if this is the place since its also related to TWRP 3.7, any help is appreicated
Got stuck in a weird situation and wondering if anyone has ideas.
Current State:
Slot_A on OOS 11, can boot TWRP via Fastboot
Slot_B on OOS 12, can only boot into Fastboot
Originally on OOS 11, booted TWRP and made backups of all partitions (data, boot, system image, vendor image, etc.). Forgot to move this to computer so this is all still stored on device.
Proceeded with OOS 12 upgrade (into Slot B). Patched magisk, rebooted, then flashed TWRP 3.7 (FBEv1), direct installed magisk, rebooted. - Everything was functional, but decided to go back to OOS 11.
Thinking I could just use the TWRP backup made on OOS 11, I did the following:
Booted into 3.7 TWRP
Restored the backup for boot, system image, and vendor image
Set active slot to Slot A and reboot
It doesn't allow me to boot into the OS (Presumably because the data was re-encrypted for OOS 12?)
Set active-slot=b and reboot, but it's locked to fastboot.
I've attempted a few things, but I can't boot back into OOS. I would prefer to retrieve my TWRP backups first before doing an MSM reset.
When on Slot_A (older), I can only boot into TWRP 3.6.2 and 3.7. I'm guessing 3.6.2 can't decrypt since it's only configured for A11 and under, but not sure why 3.7 can't decrypt my data.
- It doesn't even ask for pin when TWRP launches; maybe it's reading the System for Slot_A and thinks i'm still on A11?
- running `twrp decrypt {pin}` doesn't seem to work. Unsure if there's something done to my lockscreen pin to be used as the encryption key/password?
When on Slot_A, attempting to boot into either the system or TWRP hangs.
Things I've tried:
Flashing A11 boot.img and magisk-patched boot.img to Slot_A -> Hangs on 1+ Spinning dots
Flashing A12 boot.img and magisk-patched boot.img to Slot_B -> Hangs on 1+ logo (Does show up on ADB though)
Booting Slot_B into TWRP 3.6.2 (Official, and Nebrassy unofficial for A12) and TWRP 3.7 -> Gets stuck on "Fastboot Mode" screen (fastboot cli still responds) or Hangs on snapdragon logo
Edit: Ended up using MSM. Needed device for work

I have a similiar problem to flash twrp to my phone ,
each time i try i get a fastboot loop too and i have to reset/unbrick it with the msm tool back to android 11
i use the OnePlus_7_Pro_Global_OxygenOS_11.0.5.1 package to unbrick the phone , i dont know how long and often i tried now to get twrp to work so that i can flash a custom fw ... i want root and a android 13 based cfw but i dont get it to work :/

I got it working with crdroid. heres some stuff
guacamole - Google Drive
drive.google.com
be carefull
¯\_(ツ)_/¯​
------------------------------------
I got stable and decrypted fs RW working on crdroid 9.1 firmware other than some weird bugs
i put it in the 2023-twrp

I have the exact same problem! Have you found a fix yet? This seems to happen when I try to install Android 13 based roms, and when I install a rom like Lineage OS, using their recovery, it works just fine.

No, and I don't know why, maybe i do something wrong or it is the Modell that make this trouble.
I thinking to sell my OP7PRO and buy another one ( and then I have the same problem with the new phone )
No no let the jokes aside, it must work, i mailed with OnePlus Support Germany but they only helped me to install A11 w/root and recovery, i thought ok now I can update to A13 so I loaded A13, unpacked the boot.img, Patched the boot.img
Installed A13 w/out errors, rebooted - Fastboot loop

RIP
Started ranting instead

TWRP for guacamole development seems to be fairly scarce, last working recovery I tried was when they started using fastboot boot to enter it. It was pretty hacky even then, currently it seems that nebrassy is the maintainer for twrp for guacamole.
Github: https://github.com/nebrassy Android 12 thread: https://forum.xda-developers.com/t/recovery-12-official-teamwin-recovery-project.4269551/ Nebrassys Telegram has helpful info as well: https://t.me/NSSFB
last update I found was 2022:10:2 - https://www.pling.com/s/Phones/p/1835156
after a few days of torture I read a thread on here saying if you flashed twrp via magisk like you would if it was a magisk moule it would work normally. It worked on my device so I assume that its universal. I have filled my computer with guacamole related files Im uploading here before im forced to reinstall my os:
guacamole - Google Drive
drive.google.com
Just a fyi from what I have gathered from my experience you can get a stable twrp recovery with persistant / read write access and disabled encryption and basically use it with little error up until you try flashing a newer custom rom. My guess is when flashing a cfw the bootloader gets rewritten causing our boot image to become corrupted. Flashing twrp over / booting to twrp via fastboot or trying to install it via another custom recovery causes boot / recovery failures... meaning you cant really use it for flashing custom roms. I cant find the post with the install instructions I seen that helped me so here is what I think it was,

~ I have bricked this device constantly while ****ing around so unless youre prepared to go to war with the ****er, Id quit messing with it.
MSM flashing with windows is the only way to recover from the void.

using Linux systems for EDL is a bit more difficult to figure out but can be done > EDL https://github.com/bkerler/edl/blob/master/edl | https://github.com/andersson/qdl

~If you do brick I created a fastboot flashable A13 Oxygen os recovery rom and uploaded it to my google drive found under recovery_brick_fastboot.zip ~

lastly be mindful of a/b partition configuration or youll find yourself lost or bricked
Installation:
1. Obviously unlock the bootloader - OEM Unlock
2. Flash custom recovery (lineage/crdroid/etc)
3. (Personally I root here and again on the active slot so) flash magisk.zip
4. Reboot into installed ROM and install magisk android app and complete setup, reboot system
5. (another thing I like to do before flashing twrp) setup magisk enable all the basic options like prophide, deny list then set root userspace option to global.
6. Flash TWRP .zip (https://dl.twrp.me/guacamolev2/twrp-installer-3.7.0_12-0-guacamolev2.zip) via magisk
Alright! After all that you should be able to reboot into recovery via adb reboot recovery / fastboot or power menu and you find a working twrp recovery installed.
If you need help or want to **** around with the device you can @ me anytime and ill do my best to halp

You Confussing me a lot with your Posts before ...
i´m unsure what you mean exactly,
my bootloader is unlocked, with magisk i got a working root but after that i fail
what you mean with flash twrp with magisk ?
after unlocking the bootloader and get root, i tryd to flash twrp like before on other devices but that seems not working because i get then the fastboot loop
on another thread i found here on xda too, the guy wrote dont forget to activate the fastboot loop fix in the advanced options
but i not tried it yet again , so what should i do now ?
for now , i´m back on android11 , with stock oxygen os firmware
i have to do now the things like i did before again , unpack boot.img from the firmware that is installed on the device
patch it with magisk, flash it with "fastboot flash boot boot-patched.img" or is this step senseless ?
i mean you only wrote unlock bootloader and flash a cfw , but i don´t have a chance to flash a custom fw without a custom recovery ??
my recovery on my op7pro have no options for "install zip" or something else
addendum:
like i said you confused me a lot
addendum two:
or i do what i said before .. i sell my op7pro and buy me a one where i havent so much trouble installing twrp and root
i never had a phone before that made so much trouble in installing simple twrp ...
but i don´t found a phone yet that is compatible with kali and the pentest tools or wardriving tools like the oneplus , so i have a problem ,... i think i should drink now my selfmade blackberry liquor ( or blackberry booze ? ) and let the smartphone be a smartphone for now and power off my brain for a while

Yes, you need to patch your boot image via magisk and flash it with fastboot.
After you let magisk do its first time setup and then once it reboots you go to Magisk > Modules and flash the twrp recovery .zip file you got from twrp. link:https://twrp.me/oneplus/oneplus7pro.html just like you would if it was a magisk module.

the password for twrp decryption is your pin. Here are simpler instructions

****... I forgot a step.
after flashing twrp as a module in magisk you dont reboot, you go back to the main screen hit the install button and choose direct install

Now I understand it more, i had before rooted the phone successful with magisk, but then I made a wrong decision and booted into Fastboot and flashed TWRP in Fastboot Mode as I did it before with all my Smarties i had before, coz those way with Fastboot worked before all the time so I never thought that this is the error in the procedure
I give the twrp flashing with magisk a try.
Thx for the help

Thank @yassine2217 because I would never have done so either.... Still many bugs but twrp is twrp
