[EDIT] Never mind! I had not been reading the guide correctly, and skipped the step of actually unlocking my bootloader. Duh!
I am trying to follow a guide by KaChow to unlocking the bootloader of my Razr Maxx HD so that I can install a custom ROM.
I followed instructions to get root, and Voodoo OTA Rootkeeper says that I have root. However, now I am at the stage where I am trying to use a tool called Recovery Flasher V4 to install TWRP, a custom recovery tool. When I run the simple-seeming utility, I get this error message on the screen of my phone:
Code:
AP Fastboot Flash Mode (S)
10.9B(*) (sha-1e9f557, 2013-02-14 09:13:08)
eMMC Info: Size 32GB
Device is LOCKED, Status Code: 0
Battery OK
Transfer Mode:
USB Connected
Failed to hab check for recovery: 0x56
Fastboot Reason: Boot Failure
usb connected
The screen is black other than this message.
Does anyone have any thoughts on how I can get TWRP working on this device so that I can proceed with unlocking my bootloader?

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?
[tipo]Rooting status changed to "No" from "Yes". Can't enter fastboot mode now
This xperia tipo st21i single sim had rooting status: "Bootloader Unlock: Yes" but it changed to "Bootloader unlock allowed : No" may be after flashing 11.0.A.4.22_generic or after a failed root exploit by flashtool or some other reason. I cant enter fastboot mode now. I want to install and test some custom roms on this device. Help please...
[ images attached. Flashtool log (the only log that i have) during bootloader unlocking is also attached.]
THE COMPLETE STORY:
The device was running 11.0.A.4.27_Indian firware. It is detecting sim cards of Reliance and aircel carriers but not of airtel and vodafone carriers. So i decided to flash modems from 11.0.A.4.22_generic.ftf. I successfully unlocked the bootloader yesterday with flashtool. I was able to enter fastboot mode. I tried flashing modem with "fastboot flash modem modem_fs1.sin" and i got "Error: Partition modem not found (remote error)". I tried rooting it using flashtool but root exploit failed. Then i successfully flashed entire 11.0.A.4.22_generic.ftf via flashtool in flashmode. I tried installing cwm using these instructions but then it failed at step3 "error su not found". I had downloaded boot.img which had twrp recovery. But then, i realised the device is not entering fastboot mode with any method. Then I checked rooting status and surprisingly it has now changed to "Bootloader unlock allowed: No". I came to know that unlockable devices cannot enter fastboot mode after searching forums. Flashtool still recognises it as unlocked.. How do i access fastboot mode again? How do i revert the rooting status back to " Bootloader unlock:Yes". My ultimate aim is to install a custom recovery and flash custom roms.
I just got a new Nvidia Shield K1 tablet. It installed OTA to marshmallow latest. I try to root, I follow instructions. Getting stuck on first step, of unlocking bootloader.
adb reboot bootloader - works no problem
fastboot oem unlock - just says 'wait for tablet' but tablet doesn't have any option on bootloader to unlock recovery. just has continue (boots android normally), fastboot protocol (goes back to the same screen), recovery (goes to some recovery where it's doing nothing), etc. i try every option, apparently it is missing option to unlock bootloader?
tell me which infos i should provide to help troubleshoot, thanks
NVM, solved it.
had to sudo when doing fastboot oem unlock.
Hey guys, the dev device i have is stuck in the bootloader mode and i see device state locked.
I tried with latest platform tools
fastboot devices-->see it -> fastboot flashing unlock says ERROR. not alowed -->fastboot flashing unlock_critical-> Unknown command
odd.. is there a way to save it?cause is see that it works when you can boot in the device then go to unlcok..but im my case it does not boot at all..
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 .
