[Q] bootloader unlock fail after 4.4 with s-on and no custom recovery
I've made 4.4 firmware update with
OTA_M7_UL_K44_STOCK_UI_MR_Google_WWE_3.58.1700.5-3.07.1700.1_release_341696 which downloaded from google repository and htc1guru (they are same)
I wanted to have a clear start. i did full system wipe with twrp
i had to lock bootloader to flash RUU. so i did.
I was planning to unlock the bootloader after finished the RUU update and flash a custom recovery like twrp
then i was going to flash the rom itself.
But stuck on bootloader unlock. I cant unlock the bootloader.
Here is my current details
When i try to unlock bootloader with (fastboot oem unlock)
when i try to unlock with htcdev token code i get
but no screen appears on the screen and lock all buttons for 10 seconds
if i want to send any command by fastboot i get
After all, i decided to get an OTG cable.
I was going to mount a usb stick by that cable and flash OTA with it.
So i^ve got my otg cable connected yesterday.
Now, when i enter the recovery with connected OTG cable, the phone mounts the usb flash drive successfully but doesn't recognize the OTA zip.
I think, if it could recognize the OTA zip in the usb flash drive, i can flash the rom.
I've completely lost the phone and started to use my old nokia
Please help me.
Thank you in advance
