Re: [android-porting] Re: Question on fastboot oem unlock

2017-08-02 Thread Sooraj Sizon 
Hello ,
You should not edit the fastboot binary , if you do that it will only work 
on your pc .
You should change it in the Android Bootloader Sources 
platform/bootable/bootloader , and then flash the compiled new bootloader 
binary to bootloader partition now your custom commands will work.
But there are a lot of other things to be considered while doing this - 
 If the device has been signed by oem ?
 When you do a bootloader bring-up you will also have to configure GPIO 
pinouts for uart / serial console.
 After this Bootloader also does the function of low level hardware 
initialization such as display panel . At this stage you will also have to 
work on panel bring up.

 I have two questions and was wondering if anyone could assist

 1. Is it possible to rename the unlock command to say 'fastboot oem 
 secret_word'?

 2. Is is possible if some one unlocks the device that it also formats 
 the /system partition?

 Thanks,

 Joey
