Re: WARNING: Never Change Radio Band

What about Android Fastboot Reset Tool is it related to this?


@SiddharthJose wrote:

You've two ways to save yourself from a complete data wipe and a fresh rom install. Works without ROOT access.

 

Option One (universal except for most samsung phones)

 

1. Enable "USB debugging"


2. Download and install adb tool to your PC from "https://androidmtk.com/download-minimal-adb-and-fastboot-tool"


3. Connect your phone to PC with a data cable.
(your phone will be detected by PC at this step. If not download manifacturer drivers)


4. Allow USB debugging


5. Execute the desktop shortcut and type "adb devices" if it returns a number youre good to go.

Input the following

adb reboot bootloader  (If you are already on the bootloader skip this)
fastboot erase modemst1
fastboot erase modemst2

fastboot erase cache (optional but recommended)
fastboot reboot

 

---------------------------------------------------------

This should work.But In case youre still stuck....

 

Option Two (universal except for most samsung phones)

 

1. Download your phone's stock rom. Links: http://www.androidrootguide.com/download-stock-rom-smartphones if you cant find it there..google will come to your rescue just ask for help Face with stuck-out Tongue

 

2. Extract the rom file and identify the modem file namely NON-HLOS.bin (in the unlikely event of having a different filename, figure out what the .bin files contain using google search and copy and use the file that has the modem band information instead of the mentioned file)

 

3. Copy this file to the folder where the adb toolkit is installed (Default :C:\Program Files (x86)\Minimal ADB and Fastboot)

 

4. Connect your phone to PC with a data cable & Allow USB debugging


5. Execute the desktop shortcut and type "adb devices" if it returns a number youre good to go.

Input the following

adb reboot bootloader  (If you are already on the bootloader skip this)

fastboot flash modem NON-HLOS.bin (or "fastboot flash modem filename.bin")
fastboot erase modemst1
fastboot erase modemst2
fastboot erase cache (optional but recommended)
fastboot reboot
