Bootloader unlocked warning still shows after re-lock and 100% stock.
THIS IS NOT
FOR WARRANTY, I KNOW IT'S NO LONGER VALID, I DON'T CARE ABOUT WARRANTY, IT'S FOR SECURITY PURPOSES.
This is not so much a question, more of informing of my findings. So I finally managed to relock the bootloader of the phone, apparently it is possible with non dev version. Just had to run this with the latest T-Mobile 4.4.2 firmware:
mfastboot oem lock begin
mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin
mfastboot flash boot boot.img
mfastboot flash recovery recovery.img
mfastboot flash system system.img
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot erase cache
mfastboot erase userdata
mfastboot erase customize
mfastboot erase clogo
It is confirmed as locked in the fastboot.
However, the boot logo still have the "bootloader unlocked warning", which was what I wanted to get rid off, this is even after flashing the stock logo.bin to the phone before relocking. I also noticed that even after it is locked, I am still able to flash the modified logo.bin (that replace the bootloader unlocked warning). I guess this will have to do, however, my intention was to returned the device to 100% stock.
I can understand why Motorola does it, but it's just bad for user security to have a big label to alert everyone that your phone is insecure.
