Hi,

I have Iphone 1st gen, FW 1.4 unlocked by iPlus and was trying to upgrade to 2.02 with Winpwn 2.5. I followed the instructions here http://www.iclarified.com/entry/index.php?enid=1572, but I allways get the 1603 Error when trying to upload the Custom FW to iPhone with iTunes.

Everything goes OK, I build the custom FW, enter the DFU mode (iPhone screen says its ready to proceed to iTunes), but when I try to upload the custom FW to iPhone, I allways get the 1603 error, and iPhone gets stuck in recovery mode. I tried renaming the custom FW (deleting the custom), tried it on another PC, tried with iTunes 7.7.043 and 7.7111, no success. I tried like 10 times, no success.
I suspect there might be something wrong with the custom FW built by winpwn.

Now I have restored it back to 1.4 in iTunes and unlocked again with iPlus.
Any suggestions what else to try?

Another question, once I have the custom FW built by winpwn, can I use it directly with iTunes? (or does the winpwn put in some special state)

Apreaciate all the suggestions...

Heh, tried the Basic mode of Winpwn today, everything went OK, so I am on 2.02 now...
