In my case it was the battery connector witch not touched the board - check it, put the screws in right order and tighten them and hope it will be ok

Hi Guys! Once again KU990!
In my case it’s:
0. "please insert battery" appears.
1. The phone charges with trickle current 80mA instead of 700mA (full charging takes two days or more).
2. Battery and charger are 100% genuine, from LG. Battery is brand new.
3. That’s not the main connector (has been replaced).
4. That’s not the battery (I’ve already tried with different one).
5. That’s not the battery connector (touches the board and is assembled correctly).
6. That’s not any firmware issue (I’ve uploaded v10g-open yesterday).

I don’t have any other motherboard as organ donor. But I’m able to analyze the board and fix the problem (after finding it).
I believe it’s something around VBAT_TEMP pin (measures battery temperature). It goes directly to analog input of U200 (MSM6280_A). Maybe can I cheat the uC by providing some fixed voltage to the VBAT_TEMP analog input?

I don’t know what’s the BSI line and how to check it’s voltage (hint needed).

Any experience which can help?

If it’s unfixable by hardware side: How to increase “The Trickle Charging Current” in firmware parameters? (I've noticed they wrote that trickle current is programmable").

Thanks in advance!
Michal
