have you tried both things?
usb jig and one clock tool

Yes, i have tried both USB Jig and One Click tool...none of them worked...Jig did nothing and One click tool ends up with message failed!!!

However, it could be possible that my jig is faulty one, or the device has been bricked in such a way that neither it cant be dived into download mode even by this jig nor it can be repaired through One click.....whatever, i had given my device to expert and he has given my device back in working condition with only fault that i cannot use SIM card at all!!! Whenever i try to insert SIM, pop up appears saying unavailable sim, need to restart or something like that...Actually, I had noticed that the firmware used for my device was not from my country India and the one that was used was may be of china or one from gulf country in which there were no play store or google play service. Hence i had side loaded both apk but they could not be open even after that....So, i had restored cwm back up and i have got my stock rom back with working play store and all gapps but the sim problem starts thereafter as i mentioned above.....However, im going to flash the Indian stock rom again via odin....Do you have any suggestion for me?

Btw, expert has repaired my device using JTAG.

and.......Thanks for helping me...

SIM problem in Stock rom

Vaibhav Chauhan said:

Ok, it seems that whenever i use stock rom, sim issue appears but if i use rom that the expert had loaded after repairing my device, it works fine with no issue. However, i dont know why i cant use play store and google play services ( ok, there is no gmail, google search or any other gapps)... if possible i would post here what rom the expert had loaded in my device...

But, i think the issue is related to software problem and more specifically, to CSC file somehow....what say?

Btw, thanks for helping me....

looks like wrong country stock rom

Ryan_carte · Jul 17, 2015

Hi,
Recently, I did a Hard Reset on my GT-7562. [POWER +(VOL + VOL-) + HOME].
I wiped the cache partition and then wiped the user data.
After the reset the phone booted up and I did the initial setup [ Language, Wi-Fi & time].
Then, a "BLACK" screen showed up displaying only the time, battery status ,(network strength shows even though I didn't insert a sim) & nothing else. No apps, no home screen, nothing but a black screen.

What happened?? Did I follow a wrong method? What do I do now??
All I tried to do was get my phone back to the day I bought It.
