CHAPTER 2: CHANGING OF D301
This chapter describes step by step how to change FLASH/EEPROM-combination D301 in NHM-2/5/6 phones:
If you want to change D301 the first you always have to do is a backup of the phone identity information.

phone a new identity!

rework machine for changing any µBGA!

Start WinTesla and choose Product / Open / NHM-5 and press ok. Now you will receive the following message:
