how to check dead boot in s3 and note2


hi friends ,

this is how to check your samsung galaxy gt i9300 or gt n7100 wether its dead boot or not

first thing, you need regulated power supply,

now lets start.

for example you have dead i9300 in hand and you want to check if it can prepair via isp or s-boot clip
, just connect your dead i9300 to power supply and power it on ,

if your power supply read up to 12% or up to 15% and return to 00% after u release the power button ,
then your phone have good hardware you can repair it via isp or s-boot clip,

but if your dead phone read up to 8% or up to 10% check the power ic

if your dead phone read up to 18% or up to 20% emmc damage you need to replace it ,, tested by me 100%

the display on your power supply shuld be like this , 0.00 : 04.6
so when you power on your phone it will start reading from the left side of your power supply display , check from there,,,
