I got it
![]() For reference - my old partition table (important: always work with sector units and align to cyl=64x512 Bytes I used Excel to calculate the new starts&endings) Code:

How did you do the backup/restore for the new bigger data partition? I recommend to use tar (it preserves owners, permissions and dates of files)... Right now, after the problem, you can do it this way (from recovery): - To make a tgz of the original data partition (asumed .img in Micro-SD card root): Code:
[root (ttyGS0)]# mkdir /tmp/data_orig [root (ttyGS0)]# mount -t auto /mnt/sd/mmcblk2p9.img /tmp/data_orig [root (ttyGS0)]# cd /tmp/data_orig [root (ttyGS0)]# tar -czvf /mnt/sd/mmcblk2p9.tgz . Code:
[root (ttyGS0)]# mkdir /tmp/data_big [root (ttyGS0)]# mount -t auto /dev/mmcblk2p9 /tmp/data_big [root (ttyGS0)]# cd /tmp/data_big [root (ttyGS0)]# tar -xzvf /mnt/sd/mmcblk2p9.tgz Last edited by j0534ng31; 01-19-2012 at 09:14 AM. |

It _was_ a permissions problem
![]() I just recreated the 2p9 512MB image and dd-ed it via recovery console. WORKS ![]() BUT: this procedure is not for beginners... I'll better not write a wiki howto ![]() Regarding parted - there's no parted on recovery console ![]() Anyways, everyone familiar with dd, fdisk, mounting loop devices, mkfs, etc. should be able to do it: 0.) on the T1, make a backup of /mnt/sdcard to /mnt/extsd/backup 1.) use recovery console to dump all mmcblk2-partitions, mbr, etc. to external sd 2.) use fdisk in sector mode to alter partition table according to specs above (delete partitions 3 and 4, create extended partition 3, primary 4, logical 5...10 and be sure to place 5...8 at the same starts/ends as before so there will be no need to dd them back...) 3.) power of the device 4.) recreate 512MB empty data partition (dd if=/dev/null of=/tmp/sdb1/mmcblk2p9_512.img bs=512M count=0 seek=1 && mkfs.ext4 -F /tmp/sdb1/mmcblk2p9_512.img) 5.) fill new data partition via loop back device, be sure to keep file attributes ![]() 5.) recreate update.img from sd recovery package and replace /home/user/mmcblk2p9.img and mmcblk2p10.img 6.) do a sd recovery to flash it 7.) device should boot now, run fixpermissions.sh and 8.) restore backup of /mnt/sdcard from /mnt/extsd/backup |

Well... it should be possible to create an SD recovery image that will do it all... I just don't have the time (and motivation) for that... any volunteers out there?
I give you a Teaser: |

I'm running the latest firmware, however "um recovery" or (chgboot recovery) on the reader itself just reboots the reader, I flashed the enable-adb package, and the adb interface works fine, any hints?

2 considerations:
-I couldn't flash my dumped system (mmcblk2p10) partition. The T1 will continue failing to boot after SD recovery. Instead, I had to use the provided p10 partition in the standard SD rescue package. The dumped data partition (p9) was succesfully flashed -After resizing, I made a factory reset and a rooting to clean up things. After that, the T1 refuses to make updates and boots in recovery mode... fortunately updates can be made in this mode via usb gadget ![]() |

Poor m3l7d0wN... this is the price one as to pay for insane tweaks
![]() How did you create the new 2p9 and 2p10 images? Did you fsck them? Did you preserve file attributes like permissions? Did you run su && fix_permissions via adb shell? Is your reader partition (2p4) sane? Which root set did you use? There are root sets that flash their own 2p9 and 2p10 images.... Quote:

mkfs.ext4 -F file.img then I just extracted the .tar of the dumped partitions.. I always used tar to preserve permissions. I didn't run fix_permissions, it wasn't necessary. And I couldn't run it with the custom p10 partition since the T1 didn't even boot. I formatted the p4 partition with adb the first time the T1 booted. All other partitions were ok (I used the same start/end sector in fdisk as you suggested). I used the sd rescue set from the wiki (the "porkupan"). It would be nice (although a bit dangerous) to do a custom sd rescue with an automated script for repartitioning, with different "stages" (repartition, write p9,p10,p4) or a script runnable from recovery mode.. |

ok, I finally discovered why my image didn't work.. my .tar wasn't extracted correctly for some reason

Thanks for all informations given in this thread! Very useful before playing with contents of system and data partitions.

Hello, I'm new here.
I just rooted my device with the zeam package and installed android market. I want to install this app: https://market.android.com/details?id=gopeking.apps Why doesn't it show up when I search for it on the prs-t1? Thanks /T |
