sachit, You have not repaired the firmware. You need to rename the file dump.bin, place it in the s1fwx folder and run the repair.bat. Once you have done this you should be able to load the firmware to your player providing it is connecting properly.

After a repair the unrepaired dumpfile is called dump.bi$, the file you want to flash is the repaired dump.bin. Do not rename dump.bi$, this is your old file from the player, file is in a non-repaired state. Just to keep save as a backup. But only if it was an original working dump of course.

sachit, when you repair the firmware you end up with 2 files 1 is dump.bi$ which is the original unrepaired firmware and a new dump.bin which is the new repaired firmware.
If you are trying to load the dump.bi$ file you are still trying to load the unrepaired firmware.

Use the new dump.bin.

Yes I tried to upgrade with dump.bin which was repaired and also dump.bi$ but it didn't work...help me...
