Samsung I777 resurection complete but no download mode!

[Robi-K]

So a customer brought me a samsung I777 for flashing because it was rooted using Chainfire's root kernel, but for I9100. After rooting the phone wifi was not working at all. So I tought I'll flash it back to stock I777 and job done.

Now as I was trying to put the phone into download mode It went to recovery mode and I saw that it was a custom recovery or CWM if you will. So I took out the battery and started again but phone wouldn't power on at all. Practically dead. No connection to usb, nothing.

So I started to repair it via jtag with riff. The first 3 times it did the job to 100% the error. Tried the 4th time a all was ok. Phone succesfully resurected. Or not.

The phone does not power on at all. Tried multiple times.

Now the phone was on original firmware but rooted nothing more. It was 2.3.6 and not any other leaked firmware that may have the brickbug. I just can't understand what happened.

If anyone has an idea I'm willing to try it. I really need to get it working. Don't want to be an *** in front of my customer.

Thank you in advance.
