Hi, I'm new here and have discovered this thread after Googling a problem I have with my PRS-T1 reader; the problem seems most similar to what is described in this thread. If any of you has a suggestion, this would be most appreciated.
My reader is more than a year old. I rooted it shortly after I purchased it, without problem. I lost track of the procedure I followed at the time, as there were no issues. Also, I don't remember the firmware version any more.
Last week, my reader ran out of battery. After charging it fully, it turned on again, showing "opening book" first and big rotating arrows afterwards. It never leaves this state any more.
What have I done till now?
1) I've downloaded sdcard-rescue.zip and extracted this on an SD card. The reader boots from this SD card (using home+menu) without problem. Using Linux, I can mount all partitions, and using minicom, I can access a recovery console. This is my partition table:
Disk /dev/mmcblk2: 1958 MB, 1958739968 bytes
4 heads, 16 sectors/track, 59776 cylinders, total 3825664 sectors
Units = sectors of 1 * 512 = 512 bytes

/dev/mmcblk2p10 604496 866687 131096 83 Linux
When I run version_check.sh, I get this:

OK
2) I've reformatted the READER and data partitions. After booting the reader again, I found that the data partition was repopulated. However, the reader still doesn't leave the rotating arrows state.
3) I downloaded an SD restore package (restore-set-1.0.03.11140). I copied mmcblk2p10.img and mmcblk2p9.img to the corresponding partitions on the reader using dd if=mmcblk2p10.img of=/dev/sdb10, where /dev/sdb10 was the device that was allocated on my Linux desktop to the system partition of the reader. I verified that the partition was overwritten. However, the reader still doesn't leave the rotating arrows state.
4) I downloaded SD recovery packages for 1.0.05 and 1.0.04 as well, and tried step 3) for these packages as well. No effect. I haven't found restore packages for 1.0.00.09270 yet.
I'm at a loss what to try next. It would be very useful if I could have access to the log files of the reader when it is booting without the rescue SD. Unfortunately the reader never gets in a state where I could run or install an app for viewing log files. I cannot access the reader when I don't use the rescue SD. This appears in the log file of my Linux machine when I attach the reader:

I cannot mount sdc, sdb or sdd, however.
While using SD rescue, I ran fsck on all partitions. Most are clean, except for the cramfs partitions:
- for the Diag partition (/dev/mmcblk2p2):
warning: file extends past end of filesystem
fsck.cramfs: crc error
- for the fonts partition:
warning: file extends past end of filesystem
I however hesitate to arbitrarily download an image of a Diag partition from the Internet and put that on the device. Is the Diag partition involved in ordinary booting?
Any advice would be welcome.
