WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING YOUR DEVICE SURELY WILL BE BRICKED IF YOU FLASH THAT In do_update.sh it says: Code:
dd if=${UPDATE_MP}/tmp/ramdisk-adb-fsck.uimg of=/dev/mmcblk2 seek=10240 count=600 bs=512 Porkupan's ramdisk-adb.uimg is only 290202 bytes, no problem there, but ramdisk-adb-fsck.uimg has 555204 bytes. That means, the initrd will be incompletely written and guess what happens.... when you try to boot that.... |

Your right sick, I removed the files, thanks for the warning. I always flash the ramdisk directly without the ebook_msc/do_update.sh stuff, my fault. However I tried the script once with my ramdisk and it didnt brick the reader, I guess I was just lucky.
Anyway everybody who "bricked" his device should be able to recover it easily with the "sd-rescue" package https://www.mobileread.com/forums/sho...7&postcount=20. Because only the ramdisk is corrupted the diag/recovery partition is still fine. [EDIT] Damn I guess i hard bricked my device, I made a copy paste error and flashed the ramdisk over the device without any seek, count parameters, so I overwrite the normal boot environment and the diag partition, f**** anybody any ideas? I guess only a JTAG/serial connector can recover it. Last edited by S3raph; 01-29-2012 at 11:54 AM. |

yeah, if you write to the device (mmcblk2p) I suppose you have to open your T1 and connect to the sd :|

Unfortunately there a no JTAG/serial pinouts available and I'm a newbie in electrical engineering. Not sure if sony is going to repair it, shouldn't be too hard as all the hardware is still intact, but of course my warranty is void :/.

I'm so sorry to hear (read) that
My hope at this point is that you can somehow make the T1 boot from external sd card.... Freescale provides a bunch of tools on their website, you just have to register for free: http://www.freescale.com/webapp/sps/...sign_Tools_Tab |

Just a note back to topic: until now, I found no way to run e2fsck on sys or data partition on the device.
In recovery console, none of the e2fsck binaries work. There seem to be missing dynamic lib dependencies (libc, don't know) when /system is not mounted. So, what I'd like to have is a statically linked e2fsck or better: a statically linked busybox with e2fsck included. Anyone? EDIT: Just got it from here: http://packages.debian.org/squeeze/a...tatic/download Copied to /ebook/preload partition -> runs fine from recovery console! -> Should also run fine from init.rc A fix of my sys partition freed 2.4MB of lost disk space....

Thanks for the infos!
I have to delete the images on the preload partition to get enough free space for the e2fsck but afterwards everythings runs smooth. ...and e2fsck tells that the system partition are unmount unclean and repaired it. |
