3100 on with ufs not with switch
 

I hvae 3100 on with ufs not with switch anybody have solution ?

are you get switching voltage on terminal friend?

same 3650 flash ok with on ufs not with switch

Try to change the HELGA . sometimes it is the problem.

i think first check ur power switch ;)

right side top pin will be ~3V when ope and fall to 0V when depressed.

another problem u may see is very flat battery.

i put power supply ~4V on the battery for some second (untill current draw is ~650mA) then put in phone and connect charger. it will now charge as normal

If the switch lines are good then just Reflux UPP & UEM.

I change helga and get the result, phone is power on with switch.

dave.w is 100% right.................

what is helga. and where is the location in the phone. i have same problem. thanks

helga is RF IC (it contain haggar IC you know from dct3 plus other stuffs).

you find that on back side of phone, under the middle cage. it is the only ASIC under that cage
