I was on verizon firmware and i crossflashed to em30b firmware to unlock the bootloader. i unlocked it successfully. after that i crossflashed back to verizon rom to get rid of that permanantly locked message. but when i tried to flash ofox recovery it showed kernal crash and now i cant even go into download mode. and cant even boot into recovery.
Which method did you used to unlock bootloader? Anyway, try to unbrick it by QFIL

Hi, My moto g is stuck in bootloop (Kood/Telus version). I tried flashing stock firmware (telus) and it gave me no errors so its all good but other version firmwares like us version did give me errors! I manage to relock my phone using fastboot oem lock however, it is still stuck in bootloop. I'm not sure what else to do.
I've found a stock firmware that works for me without any errors now what would be the next step to fix my bootloop. As flashing to stock did not help. It shows warning bootloader unlocked then goes to a lighted blackscreen and repeats. I am able to get into fastboot menu. but neither factory or recovery work.
The Firmware that works without error is :
Code:
TELUS-CA_FALCON_KXB20.9-1.10-1.39_cid14_CFC_1FF.xml
Thanks!
Are you following this tutorial?

Are you entering the commands manually? Are you using fastboot or mfastboot?
Yesterday I tried to install the BR 5.0 OTA on my RETAIL AR xt1032, it failed so I converted it to the stock XT1033 br firmware, tried to install the ota, failed again, apparently only for unlocked bootloaders.
My bootloaders is locked.
So then I wanted to go back to my original rom, so I downloaded fastboot_falcon_retar_user_4.4.2_KXB20.9-1.10-1.9_7_release-keys-cid12-Latam_AR.tar.gz with the intentions of installing the OTA afterwards.
Can't boot, tried tons of gpt.bin's.
Right now I get remote failure when flashing gpt.bin and I think also boot.img
tried fastboot, mfastboot, flashall.bat /eu
When trying to boot I get
fastboot reason: fall-through from normal boot mode
version downgraded for boot
failed to validate boot image.
help will be appreciated
You can boot the phone? I mean, it works? Or stuck somewhere

It doesn't boot, when trying to boot normally it flashes the logo and goes straight to fastboot with the fall-through normal boot reason.
And I can't flash gpt.bin and other files, I get preflash errors or remote failures. I think it's because the bootloader is locked, but I don't wanna unlock it Plus I don't know If I can even get the IMEI from this point.
Try unlocking the bootloader. But im with the same problem. I were on 5.0 and then tried to downgrade to KK. My phone doesnt boot anymore.. it seems we have to wait for an official 5.0 firm

info request replies "imei: " on fastboot
EDIT: I thought I needed IMEI for unlocking bootloader .. I unlocked it and booted right away, flashed 4.4.4 br retail again, applied ota through recovery, enjoying Lollipop.
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
Tablet stuck in boot loop. Can get into fastboot mode but bootloader is not unlocked. I have tested some fastboot commands and they do work, just none which are useful in fixing the issue. Does anyone know of a place to obtain a bootloader code or any feedback on how to fix this? I have firmware downloaded and have tried the volume-/+ and power and that does not work. Just goes back to the logo page. Assume the only fix currently is through the fastboot. One other thing to note when I boot into fastboot it says PHONE unlocked, FRP unlocked which I assume meant bootloader is unlocked but does not seem to be the case.
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 .
