Problem booting TWRP recovery (Crash Dump Mode)

I has a pretty big problem of that Crash Dump screen some hours ago and i still can't get to fix it. Here is the story, after trying Havoc 2.0 rom i decided to go back to stock so in TWRP i erased the system, cache (dalvik cache and cache), data and internal storage (i wiped internal storage because TWRP just couldn't decrypt it even though the passwd was correct), after that i flashed the stock OOS rom and the TWRP installer (all these being booted on twrp), but when i rebooted into recovery the twrp splash screen just froze there, so i tried to boot twrp through fastboot, but then the crash dump screen apeared, this post: https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892 said this was a way to recover from that problem so i tried it, it worked as far as booting into OOS is concerned, but when i try to boot into twrp through fastboot the crash dump screen keeps showing up.
Any ideas?

It worked!
Now i'm installing all my mods again.
Thanks!
UPDATE:
Nevermind, it boots into twrp, but it wont boot OOS, i already tried erasing all the partitions (system, data and cache) and installing OOS and bluspark TWRP.
It turns on, shows the bootloader unlocked screen and then it reboots back to twrp.
UPDATE 2:
Fixed it by erasing all data on oneplus recovery, thanks again, my phone is back from the death (a quite unrooted one).

What's New(?) procedure to install Custom ROMs coming from OOS 9.0.5?

Hello guys,
I'm having trouble trying to install a Custom ROM (Tresk Mod, but I get it with others too)
So basically some days ago my whole Internal Storage got encrypted so I had to a full wipe.
From there I decided to use Msmtools just in case, so I got back to OOS 5.1.5 from there I updated to OOS 9.0.5 via OTA and unlock the bootloader and install TWRP everything works fine.
But when I tried to install any custom ROM I either cannot boot and just boots to Bootloader (Not even the recovery works) and I get "Failed to load/authenticate boot image: Load Error" which I can fix fastboot flashing all the partitions...
Or I straight get a black screen with the White Notifications LED whenever I try to boot either to system or recovery and from there I can only recover using Msmtools...
So I'm now asking, what are the steps for flashing Custom ROMs now?? Because seems like I'm doing something wrong since I'm ending having a Bricked device...

try to flash rom with bluespark recovery

Nothing changed that I'm aware of, but I found that I'll have the same experience if I try to root before booting the system at least once rootless first. Also, I have issues like that whenever I keep TWRP (even Blu Spark) installed. Now I only use it via sideload every time. I never have issues anymore.

I did the following:
1. Upgraded from 5.1.5 to 9.0.5 (Since I was coming from Msmtools fix)
2. Unlock bootloader
3. Reboot to system and then boot again to bootloader for doing (fastboot boot TWRP.xxx.img)
4. Once in the recovery flash recovery and Magisk (just because) and back to system (where everything was working perfectly)
5. Rebooted to recovery and did the following:
Factory Reset (The one that you slide which should wipe Cache, Dalvik and Data)
Flashed the ROM (HavocOS 2.5) and right after that TWRP
And at this point I tried to reboot back to recovery but black screen and cannot boot to recovery nor system not even via fastboot
Is your order different? Am I missing something?

You have to install twrp.zip again after havoc, boot Back Into Recovery and then gapps and magisk

Agreed. Always reboot from recovery to recovery after flashing a new one (TWRP). THEN, go ahead and flash gapps and magisk.

I finally figured it out
The problem was that as I was updating via OTA OOS 9.0.5 was only installed in one Slot so I need to install it in the other as well.
Did the following process:
1. Boot to Bootloader and do "fastboot boot TWRP.img"
2. From there flash TWRP.zip and Reboot back to it (Recovery)
3. Flash OOS Latest (9.0.5)
4. Flash TWRP
5. Reboot to TWRP
6. Flash OOS Latest (9.0.5)
7. Flash TWRP
8. Reboot to TWRP
9. Wipe data, dalvik cache
10. Flash ROM
11. Flash TWRP
12. Reboot to TWRP
13. Flash gapps + Misc (Magisk, etc)
14. Boot system
Technically just one 1 installation should do as the other slot was already populated but the twice just to be safe.

Android 10 & Custom ROM & Slot A + B

Hello Android developers and enthusiasts,
I've been installing ROM since 2011 so I would not call myself a n00b however I seemingly cannot install an Android 10 ROM without issues. So this is a plea for help and advice!
I know you need to have OOS installed before you install a custom ROM so I use Auto Flash ROM to install OOS with Android 9 via System Update. I then boot and set up phone, install update, reboot and then install the OOS android 10 via the System Update. I then have a OOS installed with Android 10.
Why would I use such an elaborate method you may ask? Well, I tried to download latest OOS from OnePlus site and wipe phone and then install OOS but that fails (didn't record the error I'm afraid).
I then download all the ROM + dependencies on an USB stick and use fastboot to flash Mauronofrio TWRP. I then follow the steps in the ROM instructions. For EvolutionX these were:
First Time Install / Clean Flash
- Have OOS 10.3 flashed to both slots!!
- Boot to recovery
- Flash BUILD.zip (TWRP built-in)
- Wipe Cache
- Format data
- Reboot to recovery (optional)
- Flash Magisk.zip (optional)
- Reboot to system & #KeepEvolving
Click to expand...
Click to collapse
I followed these to the letter but when i rebooted system I got a snapdragon error and it wouldn't even boot into TWRP until I used fastboot to flash boot into TWRP. I also tried HavocROM and same happened.
I did manage to install Syberia using above method but I didn't like the ROM that much unfortunately.
Finally, I've also read up a lot on Slot A and B but it still is not very clear to me. I think I understand it but what happens does not confirm my theories
I therefore have some questions:
- Should I be able to wipe my phone and install OOS on a wiped phone and then install a custom ROM?
- When I install ROM and it says "Reboot Recovery" and then install ROM again. But if I check what slot is being used the reboot doesn't seem to change the slot. My assumption was that booting recovery was to install ROM in the other slot. Is that correct?
Any other tips you can give me?
Again, I like to stress I am not new to installing custom ROMs so I am a bit disappointed that this is causing me such grief.
Following some answers I will retry tomorrow so I can give some more details if needed. For now, appreciate any help.

Hi!
I had this exact same problem a couple months ago. Rebooting to recovery used to change slots for me, but then it stopped.
What you can do is change active slot manually on Reboot section. By doing this, you don't even have to reboot to recovery in other to flash the other slot (altough I do it just to be safe).
And remember: the rom is flashed on the inactive slot, so after the final flash you gotta change slots one more time.

When you flash one ROM on top of another different ROM, particularly OOS to custom, always wipe data and not format data, because some custom ROMs do not support being unencrypted in the first time and then encrypt on the first boot. So do it like this:
Flash OOS
Flash TWRP
Reboot recovery
Flash OOS
Flash TWRP
Reboot system
Complete initial setup
Reboot to recovery
Wipe (not format) data
Flash custom ROM (start here for dirty flashing ROM update)
Flash TWRP
Reboot recovery
Flash custom ROM
Flash TWRP
Reboot recovery
Flash Magisk
Reboot system
I don't like built-in TWRP in custom ROMs. I always use @mauronofrio's TWRP. So regardless if the custom ROM I'm using has TWRP built-in or not, I always use the method above. I didn't have a problem with installing ROMs using his TWRP. Slots always switch when flashing ROM.

Thanks for the info, it really helps.
One question: in your experience can you wipe your phone and then installl OOS on the wiped phone?

So I just booted into TWRP, did standard wipe action: Data, Cache, and Dalvik. I then try to flash the latest OOS zip and I then get this error:
Error applying update: 7 (ErrorCode::kInstallDeviceOpenError)
Updater process ended withL ERROR: 1.
Error installing zip file: '/usbstorage/00, INSTALL/OnePlus6Oxygen_22_OTA_044_all_2002220042_a46425f1bfe43d2.zip
FIXED: I was using TWRP 3.3.1.11 and I then found out there was a newer version: 3.3.1.18 which you can get here: https://sourceforge.net/projects/mauronofrio-twrp/files/Enchilada/
I am now able to install OOS from scratch (ie wiped phone).

I tried this method and everytime I can't seem to flash oos onto the other slot because when it reboots to recovery the folder is encrypted so I can't see which file is the zip. How do I flash the seccond OOS if it shows up encrypted in TWRP.
I have a OnePLus 6 with the latest OOS now because I got into boot loop and i used a flash-all.bat to get back to stock. I also use maronofrio's twrp because that works.

If you can boot OOS fine, try to do a local update so that both slots have OOS. Then try to flash a custom ROM again using the method I've mentioned.

When you say local update you mean while I am running the rom, go to settings then do update from local source?

@Cypher_01, Try this guide. This worked for me. I did not reinstall Nikgapps. Maybe that's where the problem lies? Don't forget to change the update slot at the end before you restart.​

Possibly bricked my poco f2 pro, is there a way to fix this?

Hi all.
Today I unlocked my phone to flash the crDroid rom. First I went into fastboot to flash mauro's twrp and that worked fine. Then I flashed the miui 12.0.3 full stock image from twrp, which might have been a mistake since I flashed the full image instead of an extracted vendor / firmware version. Then I wiped system, cache and data and flashed twrp but when I tried to boot the phone it went into an infinite boot screen. Then I wiped and flashed the whole stock miui image again in the hope that I would at least be able to boot miui but that also failed, since the phone kept booting back to recovery and there was no boot screen at all.
I have also tried flashing the stock image (ver 12.0.6) from fastboot but it fails because of the anti rollback check error. The image I tried to flash has an antirollback version of 0 while my phone has a version of 1, so "current device antirollback version is greater than this package" is what I got. Now my options are very limited because for some reason my laptop can't access the file system of the phone so I can't transfer files to the phone anymore and the ADB sideload feature from twrp is not working, so I only have fastboot (adb also won't recognize my device). What can I do to save my phone? Any help is greatly appreciated.

Flash the MIUI with MiFlash.

Had sort of the same issue...
Try using adbfastboot tool ( it's a java programme ) to swap recoveries.
I got the bootloop after installing the LOS recovery , installed twrp from adbfastboot tool and got it working.
Nice to have working recovery but since adb sideload is broken in twrp i needed LOS recovery.
Tried to reflash the LOS recovery from the tool and this time it worked

Flash with Miflash (the latest version https://xiaomiflashtool.com/ option CLEAN ALL) the rom that was on your phone when you bought it.
For the roms It is better to flash firmwares with Miflash because TWRP is not 100% functional.

Man I can't believe such a simple suggestion would work but it did thanks! Initially I did not flash with miflash because it prompted me to install drivers and it crashed when I clicked the install button, turns out all I had to do was create a folder named log in the miflash directory lol. So flashing the stock image works. And it definitely boots correctly to miui with the clean all and lock option.
But now when I try to flash crdroid or pixel experience I still end up with an infinite boot screen even when using exactly the specified firmware :/ Like you see crdroid and pixelexp boot animations correctly but it lasts forever. I must be doing something wrong with the firmware still because that's the only reason I can think of why it won't boot. After I flash the firmware in miflash I don't have to boot miui up first right? I'm using the 'save user data' option in miflash if that matters.

In my post, I specified CLEANALL, but anyway, you must format data before flashing.
Which rom do you want to install Cdroid or Pixel?

I'm now trying to flash crdroid. After flashing V12.0.3.0.QJKMIXM in miflash with flash_all, I formatted data in twrp (the one where you have to type yes) but also with a decrypt & normal factory reset I still get the same result. After the format, I flashed crdroid without magisk and gapps, and it'll just hang on the crdroid boot screen :/. The weird thing is, before I flash the crdroid rom it can boot in MIUI just fine and it'll show that it's indeed the correct 12.0.3.0 in the settings so I have no idea if it's just the crdroid ROM at this point.

Flash with miflash V12.0.3.0.QJKMIXM reboot system and go fasboot when affiche "devices is locked",flash chinesse twrp ,reboot twrp,format data reboot twrp,wipe all ecxept OTG reboot twrp,flash Cdroid format data,reboot twrp flash gapps,reboot system( take time ).

Question Help stuck in bootloop!

Hello! Today i tried Lineage os (came from PPUI) thought it was nice but i wanted to go back for the extra customisation options.
Steps i did: Removed screen locks
Reboot into TWRP recovery
I wiped the Dalvik+ Data+ Cache
Realised my PPUI restore was in the wrong folder and not the TWRP recovery thought i would just reboot and move it to the corect place
Then i got into a bootloop cause i wiped my os. Now phone says storage is encrypted.
Since i have no access to storage i tried to adb sideload the LOS i had in before and then just do a freshly install of PPUI. At 47% it says adb: failed to read command: No Error, (mobile mentions a magisk module missing) Any ideas?

You still should be able to access TWRP recovery? You can format data partition there and be able to use internal storage on your next boot to recovery.

From the looks of things i have formated all my storage data in my panic state. Thoughts on moving the Rom to the phone to be installed by recovery?

So as it looks i have nothing into the phone itself and i cant send files from the pc! How would i go about getting the LOS rom to the mobile and flashing from there?
Tried Adb sideload and i get error Magisk addon.d failed can not find magisk binaries. Do i flash magisk first?
Update: I get the rom in. i Flash the rom in. and im still stuck to the LOS loading screen for atleast 5 mins Thoughts?

Fixed. for some reason it was the LOS flash that had issues. when i tried flashing PPUI it worked the first time no issues

Lineage install at 47% for poco
I use lineage recovery and I didn't encounter any magisk thingy. That sound like a previous os persistence script which shouldn't be loaded in the first place....but still did for unknown reason
However, important to note that other user flashed using twrp without issue
Try these steps
1. Format Data
2. Sideload latest firmware
3. Sideload nightly LineageOS
4. Sideload opengapp arm64 (if you are using)
5. Sideload magisk (if you are using)
Boot
