V3v after unlock wrong battery:help!!

hallo!
I successfully unlock via tp a V3v R4515 with Bootloader 0A.52.
The unique problem i face is that when i switch phone on i get the info "Wrong battery".

Any suggestion???

thank u

when you doing tp usually done something wrong , (hardware damage)

so any solution???
But it can be,bcoz i use Magic TP.So i do not touch the metal shield.

But i unlock 2 phones that way,the 2nd is ok.
I even reflash the phone with backups but no way to fix it.

Thanks

possible damage cpu with some magic tp... else no other way if you dont touched metal shield or solder..

first of all,what supply you use when you make unlock?
power supply or phone battery?
if you use power supply and make short beetwen pins in battery soket,here is your problem.
try see schematics,exist some protection like zenner diode.
if only this one is damaged,not big problem,remove and replase this one.
if not,cpu damaged and need be changed.

this is 100% hardwaredamage by wrong testpoint...or wrong handling

well,thank u all.
i did use FoneFun TPBox V2.U people surely know abt it.So i supply the phone with it and apply my Magic TP.

Weird,the 2nd phone ,also v3v same bootloader and version i unlock the same way is intact,nothing happen to it.

What is the best way to supply phone while using a TP?

there is safest way for unlocking phones with TP w/o damage , here before orbita posted one schematics for cable

just modify your cable and add one small needle connected to gnd with cable

with this one less possibility to damage phones ,for some test points don't need to cut grill, for eg: v3 , v3i , l6 there is an alternative test points

usage : just connected needle to tp then connect cable (no need external power supply) phone will be in blank mode..
