I tried to flash the pixel experience on my s10e when i tried to install the custom recovery using heimdall with "heimdall flash --RECOVERY <recovery_filename>.img --no-reboot" it kept saying "Custom Binary (RECOVERY) Blocked By OEM Lock" i found a thread with the same problem where someone suggested that I unlock the bootloader from the download mode. now when i reboot the device it get's stuck on a boot loop with "binary(RECOVERY) blocked by OEM lock" on the top and "The phone is not running Samsung official software you may have problems with features or security. and you won't be able to install software updates" at the bottom. Odin dosen't recognize it although i installed the samsung driver. But heimdall still does, i can still reboot the phone into the boot loop using print-pit.
Don't create multiple threads on the same issue.

Hi guys,
My phone won't get past the google logo anymore. I can get into bootloader mode, but now it says my phone is locked.
I can't unlock it via the "fastboot oem unlock" command. When I do that, I get a Erase fail. I can get into CWM, but I cannot restore any nandroid or flash an update.zip.
I also can't flash any file with fastboot, when I do I get "write fail". So I think the filesystem is somehow corrupt.
I tried to get into download mode via the Unbrickable Ressurector, but then I get the screen on my phone to unlock the bootloader (which doesn't work).
Anybody got an idea?
Ehy guys im having some trouble with my OPO.
First of all i can't boot to the OS, it just stuck in bootloop, and recovery is not accessible, but i can use fastboot.
Ive already used the MSM8974 tool, but after the flash the device is still stuck in bootloop.
I can't even unlock the bootloader, if i try the fastboot command "fastboot oem unlock" it just reboot and nothing happens.
Do you have some advice to exit this situation?? Ty for the replies
Ok so, this isn't my first time flashing and returning to stock with phones, just the worst. Any help is appreciated.
I unlocked the bootloader, installed TWRP and tried to flash a few ROMS which were not working great so I went to go back to stock and then the **** show happened. Its the LO4 Model. I flashed stock recovery, Relocked the bootloader and tried the Force Flash Update method. Well now the phone is stuck in a boot loop(Cant power it down), cant boot to erecovery/ recovery -- I can get to fast boot mode but the FRP is locked so I can not do anything all commands fail with an error.
Any thoughts? I just need to get it back to stock OR a working ROM- I plan on selling this phone and My wife (it was her phone) has upgraded to a Galaxy S9. If I cant get it to work, I will post it on swappa as is for a cheap price
Thanks!
Same Issue
I did the same thing, however when in fastboot type fastboot oem unlock (put the code here) and this will unlock your bootloader. I did this I even managed to flash the stock system cust recovery and boot, but it doesnt boot into recovory, erecover, or even download mode to download the software from the sd card. Any ideas?
I tried that fastboot code and I get an error because of the FRP lock
I've recently bricked my device trying to install LineageOS, long story short I had to use MSM Tool in order to flash a new, stock ROM. Since I did that I am unable to unlock the bootloader: everytime I do the phone bricks with this following Yellow message on the screen: "upgrade download failed please check your download flow is right". After that I have to use the MSM Tool again to unbrick the Yellow text.
Any ideata how I might unlock the bootloader? Aside from that, the phone works fine.
EDIT: I managed to fix this by OEM updating my device to Android 11 and *then* unlocking the bootloader. Another issue has arisen now, though: whenever I try to boot TWRP from fastboot, the phone reboots and gets stuck in the "Fastboot Mode" OnePlus logo screen. Would anyone know how to fix this, or maybe is there a way to root your phone without using a custom recovery?

Yes you can ,,install thru boot loader with ADB and fastboot CMD. First you need to extract the boot.img from your oos rom, patch it in magisk app, then put it in your adb folder and run the cmd " fastboot flash boot boot.img .
I was on A12 beta1, so I decided to go back to older firmware, I unlocked my bootloader and wanted to flash fastboot rom. When I tried it it says "Flashing not allowed for Critical partition" and when I try command:
fastboot flashing unlock_critical
It says failed, device already unlocked.
So I gave up and wanted to try MSM Tool, downloaded it and after literally 2hrs of looking for a proper driver somehow got it to work and see my device in EDL mode, but when I start flash it says "Param Preload Fails".
I have no idea what should I try next, tried everything in past 3/4 hours.
Device stuck in Fastboot mode, no booting, bootloader unlocked, any suggestions are welcome..
