Whew, we're off life support! and more importantly - my wife wont kill me for an Unauthorised Brick to The Birthday Device :cool:

Steps Performed

ADB - Write backup GPT to LBA1 mmcblk0

~ # ./gdisk /dev/block/mmcblk0

GPT fdisk (gdisk) version 0.8.4

Unsupported GPT version in backup header; read 0x00000000, should be

0x00010000

Partition table scan:

MBR: not present

BSD: not present

APM: not present

GPT: not present

Creating new GPT entries.

Command (? for help): r

Recovery/transformation command (? for help): ?

b use backup GPT header (rebuilding main)

c load backup partition table from disk (rebuilding main)

…

? b

Recovery/transformation command (? for help):

? c

Warning! This will probably do weird things if you've converted an MBR to

GPT form and haven't yet saved the GPT! Proceed? (Y/N): Y

Caution! After loading partitions, the CRC doesn't check out!

Recovery/transformation command (? for help): p

Disk /dev/block/mmcblk0: 124174336 sectors, 59.2 GiB

Logical sector size: 512 bytes

Disk identifier (GUID): 2E8491CC-AFFC-43B9-B1C4-97D2F258BE1C

Partition table holds up to 128 entries

First usable sector is 34, last usable sector is 124174302

Partitions will be aligned on 2048-sector boundaries

Total free space is 75709 sectors (37.0 MiB)

Recovery/transformation command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

PARTITIONS!!

Do you want to proceed? (Y/N): Y

OK; writing new GUID partition table (GPT) to /dev/block/mmcblk0.

Warning: The kernel is still using the old partition table.

The new table will be used at the next reboot.

The operation has completed successfully.

ADB/CWM - Exit recovery and attempt Virtuousprime ROM install

I then did exit recovery as per 1a http://xdaforums.com/showthread.php?t=1514088

Upon reboot Virtuousprime wouldn't go as far as it got before. I went back into adb shell and did wipe data:

Wipe data/factory reset

Formatting /data

Error mounting /data !

Skipping format...

Formatting /cache

Formatting /sd-ext

Formatting /sdcard/.android_secure...

Error mounting /sdcard/.android_secure!

Skipping format...

Data wipe complete

Note the error on /data. Could not format /data either using the CWM mounts and storage menu. I named the partitions I knew about and formatted /data (mmcblk0p8) from adb shell:

Number Start End Size File system Name Flags

1 38.3MB 575MB 537MB ext4 system

2 575MB 1024MB 449MB ext4 cache

3 1024MB 1026MB 2097kB misc

4 1026MB 1585MB 559MB ext3 staging

5 1585MB 1591MB 5243kB fat32 btmac

...

8 1596MB 63.6GB 62.0GB ext4 data

mke2fs -t ext4 /dev/block/mmcblk0p8

I then found that CWM data/factory reset went through without errors:

Wipe data/factory reset

Formatting /data

Formatting /cache

..

Data wipe complete

And subsequently exit recovery and virtuous prime rom have installed OK, tested across reboot and shutdown :)

Cheers!
