Bootloop after flashing about anything

Hello!
I have FRD-L09 with latest officially available firmware(FRD-L09C432B360) EMUI 5.1
I have successfully unlocked the bootloader and installed TWRP 3.1.1-1-FRD.
I have tried installing custom ROMs, Lineage and the one newer from it. Bootloop.
Magisk. Bootloop.
SuperSU. Bootloop.
On Lineage ROM, i got bootloop despite formatting data before and wiping cache/dalvik after flashing.
On Magisk, i have tried latest stable(v16) and test build(v16.6), both resulting bootloop despite if i wipe cache/dalvik or not. Magisk uninstaller works though, so i don't need to restore the whole ROM again.
Exactly same thing with SuperSU.
And by bootloop, i mean that the Honor intro plays only like 2 seconds and the phone restarts.
Any wild guesses what could be wrong? Apparently the TWRP flashes them right, because Magisk uninstaller works.

I found out o some random thread that the Magisk needs a newer firmware. Coincidentally the newest update 402 came out, so i tried to install Magisk, and it works.
At the same time the TWRP app got installed also.
I haven't found anywhere that all those apps are firmware-dependent.

How to Install Gapps on LOS roms

Ive been trying every way I can think of to install an LOS rom with Gapps. It seems everytime I try to install gapps it gives me a play store or services crash. That or i cannot boot into the Rom. I was curious if anyone had a specific package of gapps that always worked, or if there is a firmware of OOS you needed to be on to be able to use custom roms. Im just a bit stuck because I have been able to use Havoc in the past, but now I cannot even get that to boot (using the procedure that is in every thread).

If 1st doesn't work, then something has happened to a/b partition, should get fixed by 2nd

gapps issue most likley OR magisk... what version did you download? could have gotten a corrupted zip
try this first: Flash magisk uninstaller, see if it boots.
if it works, proceed with the setup. after that, reboot to recovery and flash latest magisk (17.1 i believe is latest) see if it works.

if it still giving u issues then dont flash magisk. flash magisk after initial setup.

Losing TWRP and Magisk after update

I'm running stock ROM on unlocked bootloader with root through Magisk. I've been using TWRP, but changed over to Blu_spark TWRP recently.
Every time I update my OS Ota, I lose TWRP and Magisk. The Magisk app is installed, but the ROM is not rooted. If course, if I try to install patch the system so it's rooted through the Magisk app, it says that it can't unpack the file. If I reboot to recovery to install from there, I get the stock recovery, not TWRP.
I tried to re-install TWRP and Magisk once before, and borked my phone. I had to quote and start from scratch. I lost all data since I wasn't rooted and Titanium Backup would not run.
What is the proper way to get TWRP and Magisk back after an OTA update?

Flash them after you flash update zip. If you don't you will lose recovery and root every time. Gets overwritten by stock recovery. Normal behavior

So you're saying that instead of doing the OTA update, I should download the update from here, and manually update it ? Can I just install the update? I'm rooted, (well, I was) so the OTA will only download the full update. Is that required instead of the update?
I really have to do a full re-install for every update? That sucks. A lot.

Full reinstall? No. You just have to flash the full ROM. This doesn't mean, you'll loose all your data: Just TWRP, Magisk and (if you have it) your custom kernel. You only have to flash TWRP (or simply boot into it), Magisk and kernel (again: if you have it) after the update. Done.

Ok. Cool. I tried that last time, but it failed. As a result, I'm a bit anxious about doing it again. Hopefully, I won't have any problems this time.
Thanks for the info.

I have had similar troubles as you, here's an overview of how to solve those problems.
OTA through OS:
Download and install OTA
Use Magisk Manager to download the TWRP A/B retention script and install it
Install Magisk to current and inactive slot
Reboot

Guys I am using latest blu_spark twrp. my bootloader is unlocked and I am running oxygenOS openbeta23. Following is my problem.
My flash order: (Note: already I have bue_spark twrp recovery running without issues)
1. Flash the full OTA(openbeta)
2. Flash the blu_spark twrp zip file on both active and non active slots.
3. Flash the latest magisk zip file. If step 3 is not successful means I will try to reboot in to recovery and again flash the magisk installer zip.
Until some time back all this worked fine. But for last 2-3 times although the flashing process of twrp zip on both slots ends with success message, when I reboot to recovery from twrp in order to flash magisk, the device boots in to stock recovery. I don't know how even after flashing twrp zip on both slots successfully why the devices bootbback to stock recovery. Then to have blu_spark twrp I have to connect my device to a computer in fastboot mode and then boot in to custom recovery using the blu_spark twrp image file and again flash the blu_spark twrp zip file which is inconvenient and also requires a computer.
Am I missing anything here?? If yes why this method was working perfectly before? Please somebody help.
Regards,
Sivabalan K

I flash in following order my stable updates
Flash full rom zip
Flash bluespark recovery
Restart into bluespark recovery
Flash magisk
Restart into Android
Everything works flawless. Magisk installed with all the modules running

Hi guys,
Don't you need to disable lock pattern/PIN or fingerprint/face ID? And don't need to uninstall magisk modules?
I never update my OP6 from my initial unlock/twrp/magisk and I'm a bit anxious to do it now...
Thanks
PS : I'm using original twrp (3.2.3-1), is this a problem?

That's what I was going to ask. Sounds like a module issue to me.

RenovateIce ROM (9.0)?
Try: TWRP->Advanced->File Manager->/data->/adb->/modules->RIce module, or something like that-> folder icon->delete->(swipe) and Reboot->System

Try TWRP 70

Same thing happened to me, tried almost everything one could think of , even swapped active slots to no avail, eventually found thread on fastboot flashing back to stock and all was fixed. Probably was due to unremoved/undeleted magisk modules(as others have already stated), but once the phone boot loops had no way to get modules removed posthumously......also ran magisk uninstaller to try to resolve and no joy.....like is said after a day and a half just flashed it via fastboot flashing .bat files and all was swell....mines a converted GM1915 to 1917 .....good luck!

OOS 10.3.2 -> No signal after flashing Magisk

Hello guys, I have this problem since upgrading to the latest OOS 10.3.2. If I flash Magisk 20.3, device boots without detecting a SIM, so no signal at all. And phone app crashing.
I'm using the latest TWRP (twrp-3.3.1-18-enchilada-Q-mauronofrio).
Anyone experience the same? How to get this to work? I need my Google PAY back

bro check ur imei number wheather it is showing or not dial *#06#

Same thing happenned to me. I removed magisk and all modules completely then used local upgrade and reflashed 10.3.2 OTA and flashed twrp img with fastboot. When it booted into twrp recovery I flashed the twrp installer, rebooted to back to recovery and flashed magisk from twrp and rebooted system. Everything was right with the world then. The key was re moving magisk first.

cjcool_123: IMEI is showing correctly because I reflashed ROM back to get networking ability
Hondo71: I'll try that, thanks

Hondo71: I tried that, but unfortunately with the same result.
I re-flashed stock rom to get functionality back, uninstalled magisk app, flashed twrp, rebooted. flashed magisk, booted and nothing :-/
IMEI is not showing when in this state

Might want to stay where you're at until more reports come in with the all clear or maybe there's an issue with the TWRP or the rom itself

I'd try one more time. Make sure magisk and all the modules are uninstalled. Download & Reinstall 10.3.2 full OTA through local upgrade. Then install magisk mamager. Boot to fastboot and boot TWRP recovery img. Then in recovery flash the twrp installer zip, reboot to recovery and install Latest magisk zip. Reboot system. Data and cellular should work. I lost it on both my 6 & 6T but got it back doing it this way on both.

Uninstall magisk and modules then reflash 10.3.2 from local upgrade download twrp installer and Magisk zip to internal memory, install magisk manager. reboot to bootloader, then fastboot boot TWRP, in recovery flash twrp installer, reboot recovery and flash Magisk. Reboot system. Just verified it working again on my OP6.

Hondo71: you were right, it is working now. I don't think I needed to do all the procedures you suggested, I figured out there was one module that was causing this - Native OOS call recorder :-/ I feel stupid I haven't thought about this before.
Anyway, all working now. Now I only need to find out new way how to record my calls
