Help cannot change no way bootloader.
In it the original B21 bootloader, any fimware to insert it in the display appears err.0. Only what can I put in the original rom_ci.
Of the programs I use 3.4 Upgrade and upTool21.
Can someone we can step by step explain what and how should I insert in a row in the Coship?
Means that fimware inserted in order to change the bootloader?
