Important and useful information with dead samsung android phones


Important and useful information with dead samsung android phones


DEAR FRIENDS,
SO MANY USERS FACED BIG PROBLEMS WITH SAMSUNG ANDROID DEAD PHONES.ALL ARE CONFUSED IF PROBLEMS HARDWARE OR SOFTWARE?
HOW TO EASY TO FIND PROBLEMS HARDWARE OR SOFTWARE.


Step1-First Check Phone Shot Or Not With Multi meter

Step2-Amp Meter



Connect amp meter to phone battery terminals then hold the power button(relese power button)
look this picture


phone taken the 300amp(stable).means phone power management section working perfect
75% boot problems.
you can try to repair boot with jtag or ISP

Look this picture


when powered the phone amp meter show 500amp means phone power section or IF section damaged,normaly this types of phones also heat or show shot with multi meter but IF sections problems cant show anything with multi meter.IF stage is power secondry section thats why cant show with multi meter.

look this video
http://www.youtube.com/watch?v=gkT0PP4ApZ8
when we powered the phone amp meter show 300 amp but when relsed the power button amp back to zero means power management ic make out put volt(power ic open)
this is cause is 100% bad power ic

look this picture


when connect amp meter (without hold the power button)show 50 amp on meter cause is 100% leakage the board
you find and check some power related capacitor etc.....


what you think about this information?
do you understand why i make this thread?
befor try this methode dont want to connect jtag and isp
dont waste your good time
enjoy

Sorry, but this is the common and very old way to check most of Phones
Like Nokia LG Motorola etc. which are not Chinese chip-set based Like MTK SPD

correct me if i am wrong
No hard feeling
