Thanks for the contribution to the community n0rbi!
May I ask you some dummy questions?
1. In
krafte's instructions it says for step1 that "full charged battery (charge externly not in phone)"
Charge with what, if not in phone ?
2. How do we read Vbatt1 from digital-external voltometer since the battery is on the phone?
Thanks, I'll try your "how-to" to my two siemens (sl45 and sl45i) with my two batteries (540, 650 mah) and I'll post results here.
