[HELP ME] S3 mini smartphone that no longer lights up (bricked?) - JTAG

[david6893]

Hello forum! I own a smartphone S3 mini model GT-i8190n with rom stock, root, recovery cwm and usb debugging disabled (I think).
Because of a problem with the battery I was restarting myself very often during the boot and I was forced to keep it constantly on charge ...
The other day ago to reboot but does not start and does not turn on any more, not making time to receive the new battery.

So far I tried to turn it on in all ways, including recovery and download mode, but nothing. Connecting it to the PC via USB I get a new device called U8500 USB ROM, but it connects and disconnects indefinitely and fails to install the drivers.

Could I try some solutions in this way?

I've heard of Jtag to unlock the phone and a particular image debrick.img, but I would absolutely not format anything, nor lose any data, just reactivate the bootloader.

Can I have some information on this method (steps to perform, necessary material, etc.) and if I format the phone? Is any of you able to perform this procedure by the right means?

I apologize if I have violated any rule of the regulation, in which case I will reserve the right to modify the post.

Please help me to solve ... for me it is very important!

Thanks to all those who will respond !!

The battery is dead. Replace it and see what will happen.

I hope so, but the symptoms it presents (both during the charge, which does not happen, that connecting it to the PC), do not think anything good ...

Now replace the battery, but does not want to wake up. Please help me to solve the problem with other solutions. I do not want to throw the phone.:crying::crying:

Does the Led on the screen turn on if you connected your phone to Usb-charger?
If not, there could be a problem with mainboard or LCD.
If yes, could be a problem with LCD.
It is not conducive for a long lifetime to use the device often during the charching.

This smartphone has not any status LEDs.
Now if it is charging does not give any sign of life.
So I assume it is "dead" and the only way to try to resurrect it is through jtag. Correct? Someone who can recommend me something in this way?

Are you sure that the Usb-port works?
Did you try a full charged battery?
