PRS-T1 frozen "opening book"

[jmg]

Hi,
liked I said in the presentation thread on the forum, I have trouble with my old PRS-T1 reader.
She is frozn with Opening book, each time I power it on.

Of course I try, reset action, reset and power action in same time.

I've found this lingk during my google search.

and found this section:

If your reader does not start up properly any more or is irresponsive and completey stuck, this is, what you can try.
It will take a micro-SD card and access to it from your computer.

Make sure, the battery is charged well (if you are in doubt, give it a full charge)
Shut down the reader completely (not only sleep mode). If you can't do this by normal means, press RESET + POWER and hold a few seconds. The reader should freeze and not respond any more.
Download Porkupan's SD rescue package for 1.01/1.02/1.03 firmware or uboot's SD rescue package for 1.04 firmware (Archived version from the Internet Archive). Copy the folder "OS Firmware" to the root directory of your micro SD card and insert the card into the reader.
Press and hold HOME and MENU before pressing POWER on the Reader and keep HOME and MENU pressed (this is crucial!)
Wait until the progress bar in the “Opening book" page has reached the right side (about 20 seconds). The message will change to “Updating”. Release buttons. From now on there should be no more visible activity except for the constant blinking of the orange light (within the power button).
If the reader does not restart properly after 10-15 minutes by itself (but the progress bar became again and LED of micro sd slot does not flash anymore), press RESET, then POWER.
Reader should now ask for initial settings. Also there should be a file on the internal sd named diag.log, that tells if rescue did complete.

but in my case ( I don't know my actual firmaware) the sdcard never stop of blinking, at least with power failure after few hours...

I have tried with the both firmaware rescue.

right now each time I start the reader, it freez.

and when it is connected to my laptop , it tries every 30 sec to restart and froze again.

Is there any solution, to reload the sony software like windows ISO, or any other solution to fix my trouble.

Thanks for you futur answers...
