Here is the SD card image. It has adb enabled, but otherwise stock firmware 1.0.07. Install to SD card (minimum 4 GB card, at least up to 16 GB works) using dd on a Linux PC:
Code:
unxz sd_card_PRS-T1_1.0.07_adb_enabled.bin.xz
dd if=sd_card_PRS-T1_1.0.07_adb_enabled.bin of=/dev/mmcblk0 bs=1M status=progress
You can resize the partitions quite freely with gparted. Just don't touch the unallocated space before the first partition, as that contains the kernel.
