Okay, first, let's attempt to give you an "out" if anything should go south!

1. Backup all the 94 fw files to a folder on your sdcard named "backup".

adb shell

su

cd /storage/sdcard1

mkdir backup

dd if=/dev/block/mmcblk0p2 of=/storage/sdcard1/backup/mmcblk0p2

dd if=/dev/block/mmcblk0p3 of=/storage/sdcard1/backup/mmcblk0p3

dd if=/dev/block/mmcblk0p4 of=/storage/sdcard1/backup/mmcblk0p4

dd if=/dev/block/mmcblk0p5 of=/storage/sdcard1/backup/mmcblk0p5

dd if=/dev/block/mmcblk0p6 of=/storage/sdcard1/backup/mmcblk0p6

dd if=/dev/block/mmcblk0p7 of=/storage/sdcard1/backup/mmcblk0p7

dd if=/dev/block/mmcblk0p10 of=/storage/sdcard1/backup/mmcblk0p10

dd if=/dev/block/mmcblk0p11 of=/storage/sdcard1/backup/mmcblk0p11

dd if=/dev/block/mmcblk0p12 of=/storage/sdcard1/backup/mmcblk0p12

dd if=/dev/block/mmcblk0p13 of=/storage/sdcard1/backup/mmcblk0p13

dd if=/dev/block/mmcblk0p14 of=/storage/sdcard1/backup/mmcblk0p14

dd if=/dev/block/mmcblk0p31 of=/storage/sdcard1/backup/mmcblk0p31

2. Now, create a folder on your sdcard named "flash" and copy the following files to it from the

66

fxz:

emmc_appsboot.mbn

rpm.mbn

sbl3.mbn

tz.mbn

boot.img

You will will also need the mmcblk0p2 and mmcblk0p3 files you dumped from the 66 ROM in post #35.

Copy them to the same "flash" folder. These are sbl1 and sbl2 you will be using.

3. Here are the commands you will be entering to do to the brute force flash. THIS IS THE POINT OF NO RETURN!

If ANY of these commands fails with any kind of error whatsoever, STOP! Do NOT power off the phone, do NOT reboot! Head straight to the "Recovery" section below.

dd if=/storage/sdcard1/flash/mmcblk0p2 of=/dev/block/mmcblk0p2

dd if=/storage/sdcard1/flash/mmcblk0p3 of=/dev/block/mmcblk0p3

dd if=/storage/sdcard1/flash/sbl3.mbn of=/dev/block/mmcblk0p4

dd if=/storage/sdcard1/flash/rpm.mbn of=/dev/block/mmcblk0p6

dd if=/storage/sdcard1/flash/tz.mbn of=/dev/block/mmcblk0p7

dd if=/storage/sdcard1/flash/emmc_appsboot.mbn of=/dev/block/mmcblk0p5

dd if=/storage/sdcard1/flash/boot.img of=/dev/block/mmcblk0p31

dd if=/storage/sdcard1/flash/mmcblk0p3 of=/dev/block/mmcblk0p10

dd if=/storage/sdcard1/flash/sbl3.mbn of=/dev/block/mmcblk0p11

dd if=/storage/sdcard1/flash/emmc_appsboot.mbn of=/dev/block/mmcblk0p12

dd if=/storage/sdcard1/flash/rpm.mbn of=/dev/block/mmcblk0p13

dd if=/storage/sdcard1/flash/tz.mbn of=/dev/block/mmcblk0p14

The first 7 lines are critical. Make note that I'm not having you flash them in partition order, but in the order the fxz flashes them, which is why mmcblk0p6 and 7 are flashed before 5. Again, if you see any errors, STOP! Do NOT proceed, do NOT power off the phone, and do NOT reboot or phone WILL be hard-bricked. If NO ERRORS, then cross your fingers and type:

exit

exit

adb reboot

If a miracle occurs, the phone will boot. Otherwise, you'll probably get a black screen and we can all be very sad and mourn the death of your phone!

Recovery

IF you had any error occur, here are the commands to attempt to restore from the 94 fw backup you made in step 1. This is all of them, but you will only have to restore partitions you've already flashed.

dd if=/storage/sdcard1/backup/mmcblk0p2 of=/dev/block/mmcblk0p2

dd if=/storage/sdcard1/backup/mmcblk0p3 of=/dev/block/mmcblk0p3

dd if=/storage/sdcard1/backup/mmcblk0p4 of=/dev/block/mmcblk0p4

dd if=/storage/sdcard1/backup/mmcblk0p6 of=/dev/block/mmcblk0p6

dd if=/storage/sdcard1/backup/mmcblk0p7 of=/dev/block/mmcblk0p7

dd if=/storage/sdcard1/backup/mmcblk0p5 of=/dev/block/mmcblk0p5

dd if=/storage/sdcard1/backup/mmcblk0p31 of=/dev/block/mmcblk0p31

dd if=/storage/sdcard1/backup/mmcblk0p10 of=/dev/block/mmcblk0p10

dd if=/storage/sdcard1/backup/mmcblk0p11 of=/dev/block/mmcblk0p11

dd if=/storage/sdcard1/backup/mmcblk0p12 of=/dev/block/mmcblk0p12

dd if=/storage/sdcard1/backup/mmcblk0p13 of=/dev/block/mmcblk0p13

dd if=/storage/sdcard1/backup/mmcblk0p14 of=/dev/block/mmcblk0p14

I think that's everything. Might not be a bad idea to wait a few days and let any naysayers speak up, or to let people catch any typos I may have made, because there's only one shot at this. If you're unsure of anything or have questions, be sure to ask! Good luck!
