Hi all,
I posted this in the Atrix Q&A but it doesn't seem to have had many hits, thought I'd try my luck here (here is the original thread: http://forum.xda-developers.com/showthread.php?t=1594675) ...basically my Atrix emmc internal memory card is borked and I am trying to find a way to restore it other than SBFing to factory (which is risky and a hassle...).
rickywyatt kindly told me to execute these commands in an adb shell and to post the results:
adb shell

The number of cylinders for this disk is set to 1942720.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

If i where you i'd try to leave it as if was new and take it to motorola service, they change it to a new one. If you did unlocked the bootload (i guess you did) i think that there was a way to hidde the unlocked at boot.
GL with that!
To run this commands you need a rooted device with BusyBox and parted. Using stock partition layout. You can change the partition layout to get more or less than 2GB of size for the data partition:

Hey guys. I'm doing some work to figure out how to recover Galaxy Nexus devices which are hard-bricked.. ie.. they have a bad or no bootloader installed.
the boot sequence
1. IROM - the Internal ROM which cannot be rewritten on the device. This loads the XLoader.
2. XLoader/MLO - This completes the initialization of the processor and memory, and loads up the relatively huge U-Boot ( Samsung modified this and calls it SBL)
3. UBoot/SBL - This "Bootloader" is almost a complete operating system. The U-Boot initializes the screen, provides Odin mode, Fastboot Mode as well as loading the kernel/recovery and provides a UART debugging mode (Yet to be unlocked).
4. Kernel - Once we reach this point, it's all clear.. the kernel is linux which loads android and all sorts of other things.
The Problem
People are bricking their devices at stage 2 and 3 of this boot sequence... This leaves them unable to boot Fastboot or Odin. The device is 100% interchangable with a brick. These devices are ending up hard bricked.
The solution
We must come up with a way to undo the hard brick. Here are some things i'm looking at to use the native hardware to recover itself.
When you plug in the device (when off), you will immediately notice a Texas Instruments D010 device gets enumerated. This is a debug mode for the processor.
Code:
Bus 001 Device 023: ID 0451:d010 Texas Instruments, Inc.
We've started looking at some bootloader output here: http://forum.xda-developers.com/showthread.php?t=1461986
You can find information about the OMAP4 bootloaders here: http://omapedia.org/wiki/Bootloader_Project
Help
I need help locating drivers to initialize the 0451:d010 device and make it readable from within Linux or Windows.. Generally Linux is easier to find appropriate drivers.
I could use some help collecting more reading materials and resources.
I think together as a community we can take care of this problem.

There's more to the boot then the OP mentioned... there's 6 partitions involved, not 4.
irom = hard coded
IBL/PBL = initial bootloader and primitive bootloader
SBL = Secondadary Bootloader finds linux
param = contains paramaters to run the phone and required for boot.
SBL2 = download mode (included in SBL)

Don't touch any of these files.
If you touch the param.ifs, the phone can still boot, however you will see a black screen if something goes wrong.

Ok I managed to mount it.
You most probably have an unpartitioned sdcard, clockworkmod however assumes that is partitioned and wants to mount the first partition (/dev/block/mmcblk0p1).
You can fix this by repartitioning your sdcard so that it has a mountable fat-formatted first volume and then retry.
If you don't mind using the commandline, boot to recovery and connect via adb shell to it, then mount your sdcard manually: mount /dev/block/mmcblk0 /sdcard and retry.
Technical explanation:
cat /proc/partitions lists:
/dev/block/mmcblk0 is your FAT formatted volume (no more partitions at all)
should be:
/dev/block/mmcblk0 (whole device)
/dev/block/mmcblk0p1 (1st partition, FAT formatted)
/dev/block/mmcblk0p2 (sd-ext partition, only for those that use SD2ext and such)

I can now access the sdcard, but this is only a temporary solution. How do I make it so that I don't have to manually mount the sdcard?

Can you tell me how have you solved this issue please ? I really need a fix for this issue too. Thanks.
Can someone explain me how the TPT does the booting? According to the nvidia manual there should be a BCT image somewhere on the device, either in SPI or in eMMC but I can not find it. According to this post: https://forum.xda-developers.com/showthread.php?t=2318140 there should be 16 partitions, but it looks like I only have 10:
Code:

As p1 is the recovery image and p2 is the kernel, I do not see any more partitions where the BCT image could be.
nvflash does not work on my device, as the APX mode is locked.
What I find a little bit worrying, is that fdisk says I have no partition table:
Code:
[email protected]:/ # fdisk -l mmcblk0
Disk mmcblk0: 15.7 GB, 15756951552 bytes
4 heads, 16 sectors/track, 480864 cylinders
Units = cylinders of 64 * 512 = 32768 bytes
Disk mmcblk0 doesn't contain a valid partition table
Should this command fail?
But there must be the configuration somewhere, right?
I have a TPT 1839-22G
I imaged now the whole eMMC using dd and found out that in difference to the posted partition table, the partitions BCT, PT, EBT and GP1 are missing. the Partitions SOS starts 0x100000 bytes earlier as given in the other thread.
Between 0x0 and 0x00d00000 I can find some non zero bytes but nothing which caught my attention.
Using gdisk I could restore the partition table:
Code:
GPT fdisk (gdisk) version 1.0.3
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.

Which also shows, that there are no partitions before 0xd00000.
But where is the BCT stored then?
