I rooted OP9 T-Mobile with a patched boot image of C17. Using fastboot boot patched boot.img. Then direct installed in Magisk.
I need help converting back to the stock firmware. I no longer want root and want to update the phone when updates are released. I uninstalled and restored images in Magisk and tried to take the C18 update but I always get installation error. I then factory reset the phone but still can't take an update. If I try to lock the bootloader I end up on a screen that has red writing saying it can't boot to the ROM for some reason.
Any help would be appreciated. Having a hard time finding the T-Mobile stock or how to install it, if I flash it out how to do all this

I'm gonna keep it simple, here is the scenario:
ROM is corrupted.
Bootloader is unlocked.
FRP lock is on. (fastboot can't do much)
TWRP was flashed back to stock.
Stock hard-reset fails. (even wipe option)
Force upgrade stops at 5% (swear I am using the same one)
eRecovery does not work.
Can't flash. Can't push files.
Wat do.
Model: BLN-L24C567B369 (pretty sure this was it)
Whole story:
This whole episode began when I wanted to install Magisk to use MagiskManager's HideMe feature. This required me to install TWRP recovery which inturn lead me to unlock my bootloader in the process, straightforward and went off nicely. Now it was time to gain superuser which I already had done before on another device, installing SuperSU through TWRP recovery was painless but after booting found out MagiskManager needs Magisk Root to work. I then followed Android Exlpained's article to do so. Running unSU through recovery went smoothly but running Magisk didn't, on the initial run I was prompted to use Adrian DC's BootBridge which after removing a few Assert lines ran nicely. However there was no root install, SuperSU was removed though.
At the time I wasn't sure what exactly I was doing and ended up soft-bricking by flash boot through TWRP, at this time FRP was unlocked. After many many hours I restored to stock firmware by using YMNDLZ's guide. I used BLN-L24C567B370(OTA-MF-FULL) for the img files then proceed to flash the vendor.img using TWRP and the rest (boot.img, recovery.img, system.img) using fastboot in that order as instructed. The only part which didn't work was the forced update, it always failed at 5% however after more hours going recovery mode (now stock) wiping the cache and data/factory reset did the trick (Note: my model showed BLN-L24C567B369). I proceeded to reinstall TWRP, installed MagiskManager, tried to install Magisk 16.0 which ran but didn't root me but was fine because MagiskManager's download worked. I then thought since I went through all this trouble might as well install a custom rom, EliteRom was my ROM of choice. At this point I had logged in with my gmail credentials FRP was now locked.
*Before further action was taken I took the precaution to backup my current stable stock ROM after installing EliteROM but before booting*
The steps to install EliteROM went by flawlessly, installed EliteTWRP reboot into it, ran EliteROM
went through the setup without any hiccups. However up system restart I the ROM wouldn't boot leading me to boot into my recovery only to be prompted for an encryption password (???). Since I didn't recall setting one, couldn't boot into the OS, and FRP was locked I couldn't read my own internal storage. So I reformatted the internal storage and tried what had worked before, flashing the img files using TWRP then booting into stock recovery wiping cache and data/hard reset. . . this did not work. And here I am FRP locked so fastboot isn't useful (I think?), stock recovery doesn't work, eRecovery fails connection, and force update still fails at 5% with "Software install failed!".

you have to follow only xda methods to root or change to custom rom. i have never heard about flashing stock images from twrp. i think u didn't followed elite rom instructions clearly. you need to formate data then reboot to recovery then wipe everything then flash the os in this way you won't get encription error. anyway now your frp is locked so there is no way to flash twrp so download all the available firmwares for your phone oeminfo then do flashing via dload you will get it worked.
even i was also once stuck with elite rom. i didn't liked it because missing apps icon and forgetting permission. i tried to go back to stock but stuck at 5% error. then went to google searched stock rom for honor 6x india and downloaded nearly 3 roms last one worked helped me to get back to stock.
never flash system images boot,vendor etc from fastboot and twrp unless you are on emui8 and going to try gsi roms.
hey i cant revert back to stock rom. it fails to get package from server. does jio voice calling works on this device?? if no then plz guide me how to go back to stock rom..

Register for update using firmware finder and Puts dns address in the router settings and then use erecovery
My 7 pro is rooted and hasn't had any problems prior to this. I updated to the latest OOS version a few days prior to this happening (using twrp retainer script and installing magisk to inactive slot.) The only other recent thing I can think of is that I updated my AdAway host file.
Either way I can't get into the OS proper anymore, it stays on the "your bootloader is unlocked and software integrity cnnot be guaranteed yada yada" screen before going to the bootloader menu wher eyou can choose start, power off, or recovery or restart bootloader. What happened? What can I do?
Update:
After looking at some other threads I saw something about switching the boot slots. I switched from Slot B to Slot A and got past the "bootloader is unlocked" image, but it got stuck on the boot animation. The animation was also slower than normal. What should I do? Please advise.
Reinstall the full ota via twrp, reboot to twrp, reflash full ota, reboot to twrp, reboot system. This should solve the issue ok
Is there a guide anywhere on how to do those things? Will this unroot the phone?
Is there a difference between installing ota and reflash full ota?

Just follow instructions above, just add flash magisk zip after flashing TWRP. Retain root.

I'm confused about what he means when he says install the ota, then reboot and flash the ota. Is there a difference or is that just repeating the same step? He also didn't say anything about flashing TWRP; when would I do that?
So I've got a US unlocked device running firmware version KB2005_15_200918. I've rooted it with magisk.
Few days ago I got an update notification, to update to 11.0.1.2.KB05AA. So, thinking I could do it like a pixel, I unrooted, installed the update and re rooted installing to the inactive slot (per @topjohnwu's instructions). On reboot I got stuck on the qualcomm kernel crash screen, leaving my slot_A install hosed.
After some tinkering, I was able to get up and running on slot B. However, slot A is hosed up with the update. (system update says failed, reboot to try again, when i do, hoses back up. Probably because it's setting the active slot to A again).
I've tried re-flashing the KB05AA stock boot image someone dd' and shared on here with no luck. And I don't want to use the unbrick tool, and ending up having to backup/restore all my data.
What are my options at this point to fix slot A, and take the update again? I'm coming from a pixel 3, and know nothing about flashing the factory images on this device or the best way to recover from this. Any advice would be appreciated.

Use msm tool or reflash stock via fastboot. Either way you gotta wipe one way or another.
Or maybe..
Try fastboot erase boot_a
Then fastboot flash boot_a boot.img. With the kernel you had on slot_a. Hopefully you backed it up prior to this. If not, see my first recommendation.
Thanks, I'll give my kernel backup a shot.
I hope you guys can help me with this one,
I followed the guide on Magisk website: https://magiskupdate.com/root-samsung-galaxy-a11/
Everything went well up until the final step which is titled: "Re-installing the Magisk App". This is right after I've flashed the patched boot image which was successful, I then proceeded to reboot the phone into recovery mode to reset to factory default and now I get the Samsung logo when I boot the phone, I get the alert that I'm not running official software and then it just loops through the boot sequence again and again.
I tried flashing the boot image again and again but without success.
Did I brick it? Can it be salvaged?
Thanks!
Re-flash phone's Stock ROM to get rid off of all modifications you applied so far.

You haven't unlocked your bootloader, that is why you are getting the alert that says you are not using official software. You have to unlock your bootloader before you can successfully flash a Magisk patched boot.img, it doesn't work on devices that have a locked bootloader.
As stated by the member that posted above me, flash your stock firmware to fix what you have corrupted. Then start over by finding a way to unlock your bootloader, once unlocked, you can try flashing the patched boot.img again. If you cannot find a way to unlock the bootloader, you will not be able to successfully flash and boot the patched boot.img.
Can I extract the boot image from the C48 build (last complete build for LE2115) and use it with Magisk to root my phone which is currently on C63? In other words, does the boot image change in incremental builds? If not, I guess I could revert back to C48, but that looks like a pita. This is the first time I have been without a rooted phone since Windows Mobile days due to the screwy OP updates and makes me never want to buy another OP, despite owning them since the 1.
Use that boot.img and use fastboot boot magisk.img. must be in bootloader. Then go into magisk setting and direct install and reboot. This method should be fine your only booting the img not flashing it. Gives you temp boot and root . To direct install
Thanks for the reply. But once the original boot image goes back to normal after a reboot. this means it is no longer rooted, doesn't it? I think I got into this situation on this phone before where I had the rooted version of magisk installed but it did not do anything.

That's what it's supposed to do. Boot into OOs. Then you go into magisk and direct install.
you could just use MSM tool in readback mode to download the unroot boot.img from phone to root that way. in MSM tool just press F8. select what partition you want. then click readback button.
