1- check this phone full short

3- open any power bank and remove battery 
4- connect ground black point to ground and red on battery +
just for 3 seconds. 
5- and you will gett burn capacitor like this some casees ic problem then ic will heatup use flux or spray to find
mine was capacitor 
6- finaly remove burn capacitor and phone is work
<before i was work on 2 j1 remove almost everything cap ic on board spent hours butt shortage was not removed>
butt today its took 2 second 
=================
as i write we are going to make it free eery one so post your idea and pictures here to improove and add more fetures in short killer tool
my ideas
1-can add fuse 0f 5 to 10 amp for safety  2- can add voltage regulator
battery mostly give 3 to 5 volts
butt we can rgulate and start checking from 2 volts
iff shortage not detect increas voltage 3,4,5....
Its important for board safety higy voltage may damage prints or cpu or emmc or another so start with 2 volts 
===================== share your ideas for improove your self made short killer pictures
and also comments about this thanks |
