@C10 Bootloader unlock guide

@SS2/SAT Bootloader unlock (if you have unlockcode.bin)

1. Get installed ADB/Fastboot driversand cmd - you can use OST portable (above)

2. Enable Developer optionsin android and usb debugging. Reset phone to fastboot (downloadmode) by "adb reboot bootloader" or by buttons combination..whatever.

3. Cpy unlockkey.bin to fastboot folder and type" fastboot flash unlock unlockkey.bin". You should have response "OK".

4. use fastboot-android.exe from SUT (OST portable folder). Type command " fastboot-android flashing unlock_critical". If its ok - phone screen should give a message about Bootloader unlock.

5. Enter fastboot again (download mode) and type" fastboot flash unlock unlockkey.bin". You should have response "OK".

6. Type command " fastboot oem unlock-go". If its ok - phone screen should give a message about Bootloader unlock.

7. Now you can use my OST nb0 roms to flash via SUT.

@SS2/SAT Bootloader unlock (for Android 7.1)

Download and extract attached zip (SS2- Sharp_ss2_boot_unlock_files.zip, SAT -Sharp_sat_boot_unlock_files.zip) . Manage to run windows cmd. Adb and fastboot drivers installed as mandatory,

1. Enter fastboot mode: connect usb, power off prone or restart same time pressing VOLUP + POWER, on Logo release power button. You have to see "Download mode" on screen (same thing you can do it from android with adb command: "adb reboot bootloader")

2. First of all check if you have tryes left in device-type:

"fastboot.exe oem cert_timecount get"

When is 0 you will be not able to unlock (unless you make changes) so STOP HERE! and visit here

if >0 then go to step 2.

2. Enter cmd in console: "fastboot getvar productid" -> you will get 16 digits serial number

3. Convert serial number to md5 hash ( you can to here https://www.md5hashgenerator.com/)

4. Enter cmd in console: "fastboot oem dm-verity [md5 hash generated from serial number (without quotes)]-> you should see "OK" response if you done it ok.

5. Flash this bootloader. Enter cmd in console: "fastboot flash abl unlock.elf"

6. Reboot to download mode again - enter cmd: "fastboot reboot-bootloader"

7. After reboot, enter in cmd:"fastboot oem unlock" - Get screen with unlocking!

8. Get unlock to flash critical (bootloader) partitions: "fastboot oem unlock_critical" - now you can use fastboot flash abl (or xbl) files.

Note: after accepting unlock popup on screen all data on phone will be erased!!!

When you have unlocked device repeat step 2 with commands

"fastboot.exe oem cert_timecount set 100"

I recommend to type above command each time you use fastboot, because each command used in fastboot makes this value less than before, and if it reaches 0, you will be not able to do anithing with most oem commands

You can relock bootloader anytime by cmd: fastboot oem lock

Happy rooting!
