NVFLASH Unbricker Script

Hi All,

After having bricked my tablet recently with the "booting recovery kernel image" boot loop error and subsequently surfing these threads to figure out how to fix it, I realized a much more streamlined solution was necessary.

My roommate compiled all the files from the various threads (APX drivers, recover images, etc.) and compiled them in to one executable script.

If anyone is interested, I can start a new thread and upload a script.

My Thinkpad lives again. No more flashing or modding for me!

If you send me a personal message I can supply the file directly; may not be worth creating a new thread here seeing as Thinkpad dialogue is pretty much a ghost town by this point

Script for 32GB US version. Cannot guarantee it will work on any other version. Maybe someone who has more experience with how the boards in these devices differ one from the other can chime in here.

Hi guys,

there's an option "getpartitiontable" in nvflash to download the partition table from the tablet.
To me it looks like the partition table is crap.
If it is crap, you can't write an image to a partition, because there is no partition
So maybe you have to create a new partition table.

Both of you: Pls try the following and look, if the file "partitiontable.txt" is created. Then post it here, so you can compare it.

nvflash --getpartitiontable partitiontable.txt --bl 04.EBT.img --go

Hi,

My 64 GB US tablet decided to loop / and or freeze at the lenovo screen last week. I can boot into recovery and APX mode.

looks like my partition tables are crap.

I get this when I run the above command.

C:\Users\chris\Downloads\nvflash\nvflashtf>nvflash --getpartitiontable partitiontable.txt --bl 04.EBT.img --go
Nvflash started
rcm version 0X4
Command send failed (usb write failed)

As soon as this command completes the my computer seems to disconnect form the table and I have to go thru the entire process to get it back to APX mode.

Looks like I have to re-format the partitions and or write an image to the missing tables.

Any ideas?

Chris, your boot loader is locked and unless Lenovo releases the secure boot key sbk, you will not be able to unbrick yours

Hi guys!
If someone is still alive here, could you please upload backup images for NVFlash (02.BCT.img, 03.PTimg .... till 16.GPT.img)? :eek:

    Hi.
    you do not need a firmware.
    all you need is the right partition backup, nvflash, and a computer.
    1.You have to enter nvflash mode(described in the nvflash thread)
    2.If you want to flash a partition you have to use the download command.
    It is a slow process because you have to flash the partitions one at a time(maybe you can flash them all at once but you need some batch file, and i did not find one for the TPT, and i con not create one).

    so like this:

    Writing an image to device partition:

    The recovery partition:

    $ nvflash -r --download 6 recovery.img

    this flashes the recovery to the recovery partition (number 6).


    The Kernel Partition:

    $ nvflash -r --download 7 kernel.img

    this flashes the kernel to the kernel partition (number 7).

    and the same goes for the rest of the partitions.

    note that the name of the image may differ:
    my backup for the recovery image for example is named 6.sos.img
    the command in this case will be:

    $ nvflash -r --download 6 06.sos.img

    these are the TPT partitions:

    2. BCT StartSector=0 NumSectors=1024 Boot Configuration Table
    3. PT StartSector=1024 NumSectors=512 Partition Table
    4. EBT StartSector=1536 NumSectors=1536 Bootloader Table
    5. GP1 StartSector=3072 NumSectors=512 ?
    6. SOS StartSector=3584 NumSectors=1536 Recovery
    7. LNX StartSector=5120 NumSectors=2048 Kernel
    8. APP StartSector=7168 NumSectors=196608 Applications in System/ROM
    9. CAC StartSector=203776 NumSectors=230400 CAChe
    10. MSC StartSector=434176 NumSectors=512 ?
    11. PIA StartSector=434688 NumSectors=131072 Pre-Install APK
    12. SEC StartSector=565760 NumSectors=5120 ?
    13. USP StartSector=570880 NumSectors=35840 ?
    14. PDA StartSector=606720 NumSectors=5120 ?
    15. UDA StartSector=611840 NumSectors=3234816 User Data (/sdcard)
    16. GPT StartSector=3846656 NumSectors=512 ?


    You should try to flash my recovery image then restore a CWM backup.

    I come to me a tablet lenovothink type 1838-22g wich rebooting...logo (lenovo) reboot ..lenovo reboot...

    I use nvflash
    Nvflash started
    rcm version 0X20001
    System Information:
    chip name: t20

    sbk burned: false
    dk burned: false
    boot device: emmc
    operating mode: 3
    device config strap: 0
    device config fuse: 0
    sdram config strap: 0

    downloading bootloader -- load address: 0x108000 entry point: 0x108000
    sending file: 04.EBT.img
    / 6291456/6291456 bytes sent
    04.EBT.img sent successfully
    waiting for bootloader to initialize
    bootloader downloaded successfully

    After this I created partion OK this is tutorial : http://xdaforums.com/showthread.php?t=1745450
    And my tabletet respond OK

    I write partion 6 with cwm OK (see in pictures)

    The tablet now starts and remains stuck in logo LENOVO (not rebooting - this is a step : ) )

    If I go into CWM says: cant mount sdcard (see in pictures)

    What are these commands to solve this problem?
    I saw (nvflash for asus transformes) as it would be a commands to reflash tablet.

    Does anyone have these commands (nvflash) tailored for Lenovo tablet thingpad?

    I took several firmwares on the net but do not know if they are correct for this model , and I would not want to spoil it worse than it is now.

    Best regardes

    you can not flash a firmware using nvflash.
    You can use it to backup your partitions, or restore your partitions from your backup.
    that is about it.

    so in order to make your tablet work again you have to restore your partitions from your backup(if you have one).
    If you do not then you can use my backup.
    I will upload my partitions later today when i got some time.

    In your case i think that one of your partitions got corrupted.
    You can fix that by flashing the rigth backup to the right partition.
