Hi
i'm just new & hope to get help. i had a fake sony 1GB mp4 and tried to upgrade its software but i actually damaged it. I followed all the steps of recovery mentioned in s1mp3.org and i really got to an advanced stage. I got a resemble mp4 and extracted out the Firmware to upload it to my damaged one.
The problem i'm suffering now is when i open MP3 Upgrade Tool to upload the dumb.bin and a success message appeared, after that the mp4 should be fully recovered , but in fact it lightened out and gone back to the damaged status that needs to make a short-circuit again.
Can anybody help me .... plz

I'm sorry for the so much replies it's a mistake and i couldn't delete them.
