uboot · 05-13-2012, 03:17 PM

Hi folks,

I modified porkupan's old sd recovery package such that it restores to stock firmware 1.04.

IT IS NOT APPLICABLE FOR ANY OTHER FIRMWARE VERSION AS THE KERNEL IS ASSUMED TO BE 1.04 COMPATIBLE

Kernel / initial ramdisk / boot area / recovery kernel / root fs are untouched by this package!

BE SURE TO BACKUP YOUR FILES ON THE READER!

At the moment there exist two packages.

To apply any of the rescue packages you need to unzip the file to the root of a micro sd card and follow the steps in the wiki.

1.) Charge battery to 100% or you may brick your reader on power failure!!!
2.) Power off the reader (keep power pressed until it asks to shutdown and press yes) if reader is frozen, press RESET button to power it off.
3.) Press HOME and MENU simultaneously, keep it pressed while powering on the reader and wait until the progress bar has reached 100%
4.) Now you can release HOME and MENU (this is crucial, don't release earlier!)
5.) Now it will take up to 20min for the rescue process to finish
6.) Reader should reboot automatically, if not - assure that the LED for the micro sd slot does not blink anymore and press RESET. Release and power on the reader.
7.) 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.

Package 1
The package does

1.) format reader partition (=internal sd card, mmcblk2p4)
2.) restore data partition from porkupans recovery set
3.) restore 1.04 system partition from porkupans recovery set

This package has been reported to work.

Download: sdrescue_1.04_porkupan.7z (72.332.505 Bytes)

--------------------------------------------------------------------------

Package 2
This package is supposed to

1.) format reader partition (=internal sd card, mmcblk2p4)
2.) format data partition mmcblk2p9 such that it get's re-initialized on next boot
3.) restore 1.04 system partition on mmcblk2p10 with stock files, but reformated file system to have more inodes which is handy for rooting the device later on (busybox creates lots of symlinks which consume an inode each)

Download: rescue_1.04.zip

There are reports of the reader being unable to store settings with this packages and asking for initial settings on every boot. I don't know why because the formating of the data partition is done exactly like factory reset would do.

Anyways - there are also reports that this package works. So, if you try the 2nd package, please report back to me if it works!
