[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.
