Corrupt partition table or fried emmc? - G2 and Desire Z General

Hi Guys,
I've been researching about this topic now for quite a while, but i am still not certain, whether if the eMMC of my DZ is fried..
Story is as follows:
Just rooted my newly bought DZ (lost my old one )using downgrade, then gfree, everything went fine so far.
After that i went to recovery, flashed virtuous affinity and rebooted. I gave it time to boot, but it got stuck on the "loading initial setup" screen (waited patiently about 20 mins or so). I thought it would be no big deal to pull the battery and let it boot again (Did this with my previous DZ numerous times and all was fine)
On second boot nothing happened, so i checked recovery and saw that the /data and /cache were obviously corrupt. Formatting was not possible by any means, neither by the tools in recovery, nor through flashing superwipe.
I can confirm that my eMMC is one of those possible faulty M4G2DE, see: http://forum.xda-developers.com/showthread.php?t=1039504&highlight=can+t+format&page=3
But it is mentioned in the thread, that it could be either a faulty chip or a defective partition table, which should be possible to rebuild either with a RUU or by adb shell:
Code:
mke2fs -t -ext3 /dev/block/mmcblk0p27
It was also mentioned to check whether
Code:
cat /proc/kmsg | grep mmc0
would say anything about an initialization error, which is not the case for me:
Code:
cat /proc/kmsg | grep mmc0
<3>[ 7.565124] mmc0: No card detect facilities available

I know, from this point, being unable to do a RUU, nor flash a PC10IMG.zio via fastboot, nor recreate partitions in any other way, would suggest that the eMMC is fried and i should see that i send it in for repair.
BUT
I came across this:
http://tjworld.net/wiki/Android/HTC/Vision/EmmcPartitioning
Basically he is saying, that the hboot is trying to create an extended partition on the end of the blocks, if unallocated blocks are still available this should do no harm. But if the disk is fully partitioned, it simply overflows and creates the partittion at the beginning of the disk. According to that, this causes the usual tools to be unable to reformat the disk, because they get stuck in the same overflow.
He mentions a way to fix this, by unallocating the last partition, but i am not sure how this could be done.
Can the hboot be the problem? The new DZ runs eng hboot 84.2000, on my old one i used to have the normal pvt ship (see sig)
Maybe some of you would like to help me think
And maybe we can find a solution for some of the fried eMMC's

Hi Xadro
unfortunatly i have currently exactly the same problem. I can't manage to format the system partition (mmcblk0p25) and the cache partition (mmcblk0p27).
Do got any solution for it?
Thx in advance
Chris

Small update:
I managed to format each in 4EXT with tools formating to use ext3. Now my info is showing me the attatched screeni. Before that he crashed everytime when I opend that view and system and cache was ext4 but also without size values.

Kind of an awkward way of thinking, but... I see that you have a 32GB Sd Card.
Could that have any link to your problem?

Mhh dont know. Shouldn't as i never had problems before.
My target was to use Android Revolution HD 7.0.2 and I may should add the whole story in short form:
followed http://forum.xda-developers.com/showthread.php?t=1178912 to do a downgrade -> worked perfectly
followed the rest of http://forum.xda-developers.com/wiki/HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD to gain perm root until step 7. -> worked perfectly
used http://forum.xda-developers.com/showthread.php?t=1493404 to gain a new rom
it was written to use 4EXT -> so installed what worked and also the info was displaying the correct sizes
applied ZIP and restarted -> waited 30min but only boot animation was displayed and after some time it restarted -> boot loop
applied the ZIP again -> same result
found in http://forum.xda-developers.com/showthread.php?t=840040 to load SuperWipe...what i did and it reformated worked with out error
applied ZIP again
didn't started anymore -> stucked there
During all the restartings it can be that i may interrupt some important "reallocating" of partitions...but not sure.
But I can try replace the SD with the original one. But not thinking that it is a problem, cause it is normal accessable :/
Any way big thanks for trying to help me!

try a fastboot wipe, cleaner than even your best superwipe - then when you pick a rom to flash pick an old tried and true like the stable cm7 or miui.us

Hi,
unfortunatly that didn't worked
if I start "fastboot erase system -w" (i think you ment that) he just writing "erasing 'system'..." and just stops there. my phone is displaying the whole time the fastboot white screen, but i can't do anything there anymore (vol up/down...). I waitet 2h...only could remove battery
I realy appresiate any other recommendation :/
Update:
Also this hangs:
Code:
./fastboot -w
erasing 'userdata'...
ERROR: usb_read failed with status e00002ed
FAILED (status read failed (No such file or directory))
finished. total time: 3627.265s

Phone needs to be in flashboot usb, and when you open cmd on your comp you need to open it to where you have fastboot stored or change directories to it. Or you can add it to your variables and open it anywhere.

Sorry for answering a bit late, but was in weekend holidays
Of course i did it in the fastboot folder and my phone was in fastboot usb (red blinking on phone screen). Otherwise i would get "<waiting for device>". Just got that error message posted above. Any ideas left? Otherwise it seams to be a broken eMMC

So when conected phone displayedfastboot usb in red? If so when you typed fastboot devices did it display one?

Yepp, it does show serial and "recovery".

And if you try to flash the hboot/spl now what happens?

Hi again,
I tried to flash the hboot while in fastboot with following message:
Code:
C:\android-sdk-windows\platform-tools\rom_26>fastboot flash hboot hboot_7230_Vision_HEP_0.85.0005_101011.nb0
sending 'hboot' (1024 KB)...
OKAY [ 0.183s]
writing 'hboot'...
FAILED (remote: image update error)
finished. total time: 2.904s
Also tried to do it with "dd" what seem to work but as soon as i restart the phone it still says it is in an "VISION PVT ENG S-OFF" while i was flashing a non-ENG hboot...and the version also not matching "HBOOT-0.84.2000" while flashing 0.85.0005
I also tried to put a newer (2.42.405.2) PC10IMG.zip from RUU on SD Card but it fails with message "BOOTLOADER - Fail-PU" and "Partition update fail! Update Fail!"
I realy think the eMMC got bricked...If you do not have any advices anymore i will look for a replacement from somewhere.

I still searched around and found that post: http://forum.xda-developers.com/showthread.php?t=1039504&page=6#post14645519
Its exactly my situation with same outputs and also the "bad" eMMC. I will try to send it in. Reading all that i have to admit that i already had before trying rooting it, i couldn't do a normal restart (just had a black screen after splash screen). It must have been connected to USB to be able to do a restart. So I think i didn't done anything wrong...just have a hardware issue

Sorry for not answering you chrisdeath, was busy with other stuff lately, so i hadn't had the time to stop by here. Have you been sending in your phone already? Telling from the stuff you wrote earlier, it is very likely a fried emmc. There is a way to confirm this, using two shells. With one shell, you need to display the log using
Cat /proc/kmsg ¦ grep emmc0
With the other shell, try to do any kind of write access (e.g. format partition or dd anywhere)
If there are any errors in the log referring to the write fail, your chip is bricked.
It will probably get fixed free of charge, even if the phone is rooted, others have told me that they got it new without payment. If your new one has the same chip, you should if by any means possible, never pull the battery during operation, as this seems to be the main cause for bricking the chip.

Finally a Fix For Bricked Emmc?

RIFF HTC via USB cable support
- Important information !
This is discussion thread for HTC Models support via USB cable.
Currently, the following models are supported:
HTC Desire HD
HTC Desire S
HTC Desire Z
HTC Inspire
HTC Incredible S
HTC Incredible 2
HTC Thunderbolt
HTC Flyer 3G
HTC Flyer WiFi
HTC Sensation XL
HTC EVO View 4G
HTC Glacier
HTC One V
HTC Radar
HTC Rhyme
...
Basically, Any HTC model based on MSM7230, MSM8255, MSM8255T, MSM8655m MSM8655T CPU is supported, combined with Qualcom EBR/MBR Plugin tool.
This feature is mainly designed for users who can (and need) replace eMMC chips in HTC phones. Following previously established error 0x44 irrepairable problem, this method enables You to repair any HTC model from supported list.
Requirements:
RIFF Box
RIFF JTAG Manager v1.43 (Cointains JTAG Manager v1.43, firmware 1.32 and drivers installer)
RIFF Box Firmware v.1.32
Original USB Cable
Test Point cable (Optional)
HTC MSM8x55/MSM7230 based phone
How to use HTC via USB RIFF Box feature:
Read this
and this
So basically jtag manager can unbrick with QHSUSB_DLOAD Mode, not even needing the RIFF BOX in the process
so why cant we make software that doesthe same?
This will not repair bricked or damaged/faulty eMMC chips. The process requires to short VDD line of eMMC to gnd which is a bit risky. With this tool, you can just re-write the partitions including boot, sbl1,2, wlan and almost every part of the eMMC including GPT/MBR. Bricked or damaged eMMC are only repaired by replacing them with a working one.
the bad side is 98% of emmc fault is due to Hardware , where software solution are useless .
I have jtag soft , but each time I got this kind of problem they never solved ... 4 Desire HD same issues nothing repaired by riff or else .
@funkym0nk3y is 99% right , less are solved by software , just advertising they tools .. but anyway no bad to belong its .
If your phone gets bricked by flashing incorrectly or bad update only..., obviously if hardware is damaged the only option is to replace parts, but the point remains that software exists to ressurect boards via USB QDLMODE, there's lots of people looking for such solution, people that cant afford to pay good money for repairs,
The fact that you state you have to solder isnt completley true as I bricked my emmc and all it does is qdlmode when you plug it into a pc.
For example HTC evo, Evita, Samsung note, sensationxl, when bricked automatically start in qdl mode

eMMC death is basically "physical" damage; it can't be repaired by software means.

and according to riff box program , some emmc bricked can't be solved if even it happened via software . 20% repairable
@legija
Tegrak kernel causes something unrelated to current issue, it causes "lockup bug" which is something different.
In that case - eMMC gets locked after bad address sectors are accessed causing either system freeze or restart. This can be solved either by kernel patch which was released on google code project, or by replacing locked eMMC.

Hello everybody,
Hi everybody!
When I tried to return to stock RUU-Pyramid-ICS-hTC-Europe-3.33.401.6-Radio-11.76A.3504.00U-11.24A.3504.31-M-release-266171-signed.exe rom, the installation stopped at 39%. It haven't finished after many hours. I unplugged the usb cable from the phone, started again, but still the same. Stuck at 39%. Now I have flashed a factory firmware, and I can start the phone in HBOOT, I can access the phone from computer in fastboot, but I still can't finish the update process.
Can this be caused by a corrupted eMMC?
I have this problem in ONE M7 S-ON
no solution to restore; ;
thanks

So I guess my emmc-chip is OK. Why does RUU stucks at 34% if everything is OK??? It has beeb around a month since my recovery (TWRP) corrupted my inernal storage and I managed to make everything mountable. No RUU works though and no custom ROM can be flashed in my phone... Any kind sir to help please?
PM I guess I have searched every thread but I can find no answer other than SD mounted ROM(which is TOO slow) T_T
It can't fix the damaged eMMC. I tried all these boxes. My G3 eMMC is damaged and need a replacement

[Q] bootloader status: partition table is invalid

Has anyone found a fix for this? All I can find are posts from people who say they had this same issue and then no answer to how to fix it.
This is a stock tablet, never been rooted. Only used for regular people tasks like checking email and such. It's never been modded in any way.
I'm stuck in APX mode. Can't get into BL, Recovery, and can't boot.
When I power on I get black screen with no logo or vibration and power light is white. Doesn't matter what vol button I press during boot.

UPDATE 1/20/2014:
From what I'm reading on the forums it appears as though my a500 has a faulty memory chip on the motherboard as per this post:
dibb_nz said:
Download Links to Unbrick your Tab
This can happen "just like that" for no particular reason or after an OTA - if this is the case, its more than likely caused by a faulty memory chip on the motherboard - the ONLY fix for this is a replacement m/b from Acer..

you are not alone!
I don't really have anything useful to offer other than "me too." Same exact results.
At this point, I have tried just about everything I have read (it's a brick, what more damage can I possibly do?) to no avail. If I find anything else, I will certainly post back!
D
is there no a500-healing wonder?
i can enter apx mode, execute nvflash from babsector or timmydean and get always errors concerning the creation of something (see pics) is this a hardware error, does it concern read/write rights or something else?
i thought, i could reinstall the device, but as a far as i read this is not that easy...
is there no possibility to erase the whole thing and start from nothing?
on the other hand, i can get into recovery mode, the green guy lies on his back and seems to be in maintainance. injecting several (about 5) update.zip on sd card went up to 95% ONCE ... and never again.
i will not directly sceam out for help, but if there is an possibility to get the device running, i am very interested.

There is no real solution for your problem. From your pics the first one shows the faulty emmc.
The "bct write error" in the 2nd one. Well theres only apxflash that can repair that, but as you've found its not foolproof - in your case I would suggest that both these errors together are fairly strong indicator you have a faulty memory chip.
A couple of folks recently have managed to get acer to repair their tabs for free, even tho they have been out of warranty - so thats worth exploring -
There have also been new motherboards on ebay $50 US and others have had joy replacing them themselves.

at least it is constructive news not leading to another how-to(-get-rid-of-your-leisure), even without growing motherboards on my balcony.
the funny thing is: i have a second a500 with the same error. i bought them (one by accident) used as they were announced having a bootloop. my mobile had one, too, that was easy to solve, so i thouhgt - as my mobile is older than the tablets - shouldnt be a problem to fix. vital error, it seems.
i´ll try to get one mainboard, but they are pretty expensive compared to the devices prices.

Hello dibb_nz
the two devices i own did not power off spontanously in any state. it happend after about 5 or 10 or more minutes stuck on acer logo, they turned off, but this happend on both devices, so i did not keep it as unusual.
since i baked them today and installed 3.2.1 for instant, they behave mostly normal. only in case of using flashplayer with firefox beta, i had two spontanous "shutdown & restart-events" on one device. this may be caused by FF beta and flash. Other flash-apps work properly.
i am reallly happy about the oven-hint, i was already watching out for a new board. not easy to get one for less than 70 Dollar from the other end of the world. i hope some other can benefit from the oven-method, too.
Hey thanx 4 the kwik reply m8 plsd u up n running again and hope all goes well
Sent from my HTC_PN071 using Tapatalk
i'm glad to see this oven method worked for a couple people. I have a SKINOMI Case on my tab so I will probably have to remove that to get to the board, but better that then to still have a bricked tablet. I hope it works!

D802 bricked, tried everything

Hello everyone. Here's my story
I've been using CM13. After installing their OTA update it ruined my android. So I downloaded new cm13 rom, wiped everything, accidentally clicked reboot (without flashing new rom) and it was over (At least I think this happened, it was some time ago and I'm already trying to fix this for a long).
I am stuck in LG logo. Can't access recovery (I've had this issue before. Could get to recovery only by command from adb).
I can get to Download mode. But PC can't see my device. Tried several PC's, windows, ubuntu. I flashed other phones with this method, only G2 is not visible. I'm doing here everything fine.
Also I tried this:
http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
Success but my phone keeps flashing on and off. I've got access to partitions like every 5 seconds and only for a second. I think I managed to flash those 3 partitions, but there's no difference, pc still can't see phone when in download mode.
Should I trow it to the ocean?
Keep it
Here is my story
Bricked my device (d802) with your stuation no recovey no download mode
My phone's partition table deleted any way, tried wire method which you've already tried
Tried several times and release this wire method put in 2 seperate modes
Found the mode it shows in ubuntu a sda block (with several tries with wire method)
I've got full 32 gig backup, thats my advantage between your stuation
In ubuntu fdisk - l shows all disk and shows my phone as a disk but no information about disk or partitions etc. only sda block
In the end pushed the 32 gig backup with dd if=/(path of my backup) of=/dev/block/sd* bs=4k
Wait some time until process done (30-45 minutes I guess)
Thats all, phone boots normally everything is fine
If you're using 32 gig version I can send you my backup (with imei deleted) so you can boot your device and install kdz
Or I can show you how to backup another LG phone and recover from that backup. http://forum.xda-developers.com/lg-g2/general/how-to-backup-data-16-gb-32-gb-size-t3236558
Thank you for your reply lynxrz
I've got bigger problem. When I enter qhsusb mode, backlight of my screen keeps switching on and off every 3-4 seconds. I can see partition only for a second.

Not necesaary to see partitions
In ubuntu or any linux enviroment open up a teeminal emulator and "sudo fdisk -l" and it will be like that;
Code:
$ sudo fdisk -l
Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00008ec7
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1013 8136891 8e Linux LVM

sda sdb sdc means a phisicial disk. sda1 sda2 sda3 means partitions of "sda" disk. My process depends on overwriting sda disk not partitions, so you don't need to see partitions
Just type "sudo fdisk -l" and tell me you can see any sdb sdc phisical disk permenately. We must know connection can be dropped or not(it can be bootloop). Partitions might disappear but phisical disk have to be there. Look for it.
If you can't see in qhsusb mode try another mode, this is the lucky part of tring the wire method. I don't know exactly how to swich "another" mode but you can detect in window device manager, then switch to linux (Don't be afraid to losing this mode it stays when you plug off usb if you connected battery)
Sorry I don't remember that "another" mode's name but it is exists
Firstly you need to know qhsusb mode can see a "phisical" disc or not?
I'm in work now, but I tried this yesterday.
Phone appears as sdc when I typed
Code:
$ ls /dev/sd*
while in qhsusb mode. (I had to type it several times repeatedly to catch the right moment)
I can get to download mode, so I typed
Code:
$ sudo fdisk -l
and couldn't see sdc there.

Probably it can be bootloop.
Did you plug off the battery when touching capacitor ? Just asking to be sure.
Sure, I unplugged the battery So qhsusb not stable and download mod not visible to computers.
I already gave up of hope
Ok I will solve how to enter "another" mode (not qhsusb)
But I need time to backup all my data in any case
If I solve, prepare a backup for you and it'll be 32 GB
Edit: Can not find out "another" mode because of data cable problem (severed usb cable charging but not transferring data) You're on your own now to find another usb mode, It can be the "holding time" of cable on capacitor.
Good luck with that
Prepairing your backup with otg
Really thanks for your help lynxrz. I appreciate all effort

You're welcome
PS: Did I send pm the download link?
You did. 29.1GB rar file. I have no use for it till I find another mode to be able to flash partition.
I already bought G3. Probably I will sell G2 for parts
Uploading now and it was %17 maybe tomorrow will be uploaded %100
20,4 GB and compressed seperated 1 GB rar parts (21 parts)
Realised by you broken usb, I'll solder it but no time for that now, 2 days later I'll try it.
I'm stuborn as hell with that Just wait we'll fix it don't sell
Maybe I can make a tutorial and help the others
UPDATE: Usb works I'll try it tomorrow

shield TV 2015 bricked ?? no root no update...

Hi,
I never root or do anykind of development or advance usage of my shield 2015 pro,
but about 15days ago it just deside do not boot anymore . i don't think it got the last update, so i have no clue why it suddenly not boot anymore
The green light is there, but there is no output.
i tried to invoke the android fastboot with this nethod : http://nvidia.custhelp.com/app/answ...NNXg0SmNhUFlvNHpHMGkwM29mRlZxTVdQUVElMjElMjE=
i also tried to factory reset with :
http://nvidia.custhelp.com/app/answ...hen-you-are-unable-to-access-android-settings
but didn't succeed to see anything, there is no output at all (the TV says so, and i try other stuff the TV works)
i don't know what to do ?
is it actually bricked ? can i do somthing about it ?
Thank you in advance

You didn't mention it so i ask, did you try with other HDMI cables? If still no go and as it is the pro which is more tricky, then better request RMA.
Have you also tried running fastboot commands blindly? I mean do the steps to boot into fastboot/bootloader mode, then if you haven't installed windows drivers try to do so, check device manager, does it recognize your device? What does it show?. If your device is recognized by your PC in fastboot mode and you succeed to install drivers then that will tell us something, otherwise is hard brick but still could be a hardware issue.

Hi,
thanks for trying to help me,
I tried the cable with another device so the cable is fine
i tried the fastboot blindly but no success (maybe/probably/hopefully i don't do it correctly )
about windows i didn't saw it on windows at all, but that wasn't worry me at that time because i didn't know where to look, so i thought it was maybe normal
about driver no idea of what should i do. during my search i saw little bit about adb
all my search bring me to topic where people did stuff to there shield (root, try rom , etc) i didn't do anything so i don't know what information is relevant for me or not
tonight i will install driver and try again.
just to summarize :
After installing the driver:
- if i see the device in the device manager there is hope
- if not it's hard brick and so i can do nothing ?
if that true ?
thanks you
I would have a look at the SSHD to SSD migration Threads here on XDA (Shield TV), and attempt to make a backup of the SSHD. (If possible). This will of course be of MAJOR IMPORTANCE if you wish to retain any of the Widevine L1 DRM Provider Content (e.g. Amazon, and Netflix. etc.. etc...)
It seems to me that the Bootloader got wiped / corrupted (Which is actually the good news), or the SSHD has died. (Well it probably can't get worse than that.)
In the SSD Migration Thread there is a link to download an Backed up version of someone else's Shield TV. I managed to use this to recover a hard bricked Shield before. My mistake was not making a backup of the Security Sectors of that Device, and I lost all those Services.
It is however possible to rewrite that backup over a working backup to recover the correct L1 Widevine Keys though. IF YOU REMEMBER to make that Backup first. So it's probably​ not too late to do that. The worst case scenario? Your just gonna lose a buttload of DRM Services that you may, or may not even depend on. If your more of a Kodi Person, than this shouldn't even affect you much. But, of course it would be wiser to try and, retain those Widevine Keys if possible.

Right, if your PC recognize your shield in fastboot mode then it means is alive. When people have hard bricked their devices by corrupted bootloader some are able to boot into APX mode, which confirms their device won't be able to recover (unless Nvidia release the tools), but for others the device won't even turn on.
If your pc recognizes your shield tv in fastboot mode and you are able to install windows drivers and you get an id when typing fastboot devices in cmd, then there is a 50/50 chance of recovering, don't forget the possibility of hardware failure.
The following video can help you, just follow until i open command line and start typing fastboot commands but you just have to type "fastboot devices" command nothing​ else, if you get an id it means that the link with your shield tv is successful.

Report back!. Oh but still try other good hdmi cable(s), i tell you for experience, weird **** happens. I have had weird issues with hdmi port and hdmi cable (Amazon basics brand) in the past.

to entering the fastboot mode the only way is pressing for about 3sec after powering up or thanks to the drivers it will enter automatically ?

someone ? do you have any idea ? what could i do ?
Did you follow this Guide?* Essentially you make this backup in Two parts uninspiredly called "firstpart.bin" (Which is the first Six Gigabytes of the SSHD which also encompasses​ the unique DRM Keys for your Shield.). The lastpart.bin is more or less just the list of checksums for the GPT Partitions.
I wouldn't expect that you would, could or should be able to see anything from the Drive. As most of it is written in a RAW Partition. That is personally beyond my knowledge of how to mount it. That's why you have to make *.bin files which you can then view with a Hex Editor. If you wanted to.

i did follow this topic but the problem is that dd doesn't works event fdisk don't work
Code:
[email protected]:/mnt/raid/backup/shield# fdisk -l /dev/sdb
fdisk: impossible d'ouvrir /dev/sdb: Aucun fichier ou dossier de ce type
it's fdisk telling me that it can't open my drive sdb no file or directory
i even tried ddrecue so i feel like i'm screwed
but i don't understand because i never saw this kind of problem with dd, i mean even a damage drive i always could start at least , copy a few bytes ... i don't understand what i miss ...
Did you remember to enter elevated root first?
Code:
$ sudo -s
If you don't do this, or you just throw up a sudo fdisk -l. I don't think it'll work. You have to be in an elevated root shell first.
Then you can use:
Code:
# fdisk -l
To list all the Drives currently in your System. Which will be more complicated depending on how many Drives you have.
Again this should list all the Drives currently on your System. You can easily, spot the Shields SSHD by the fact that it is exactly 499GB. Within in this context is the Drive Address. For me this has always been /dev/sda. Where as the local OS was on dev/sdb.
So when you get to this point:
Code:
dd if=/dev/sdX of=firstpart.bin count=6899870
You need to replace sdX with the correct Address of the Shield TVs SSHD. This will then hopefully create a ~3GB File called 'firstpart.bin'
Likewise
Code:
dd if=/dev/sdX bs=512 skip=976773158 of=lastpart.bin
Will create a 5kb File that hosts the Partition Map?
Again you have to replace sdX with the correct Address where the Shield TVs SSHD is hosted.

i don't know what to do
I bought a new adapter because at first i thought it could be the adapter but no it's the drive that is like dead. so i bought a new drive but because i can't get a backup of the old one i don't know what to do
can i find somewhere a full backup that i could put in my drive ?
thx
i try to copy with dd and ddrescue, until now i got 0 bytes rescued so i guess my only luck would be to get a backup somewhere else, but even there would i be able to run netflix ?
You should contact Nvidia for replacement, hardware died, not your fault. Unfortunately if you didn't backup the relevant partitions containing your keys, then no you wont be able to watch Netflix.

Hiyas. Welcome a fresh corpse.
Shield 2015, non-pro, bricked by flashing a wrong image.
Bricked well, no adb, no screen, no button - just green led on powerup.
Nvidia says there's no official service in our swamps (lovely, huh) and I'm up to myself.
Anyone with succesful revival? Thanks guys.

Bricked Nook Glowlight 3

I installed relaunchx and rooted the device sucessfully. It was running okay. I set the home button to restart in relaunch rather than the nook software. I rebooted and all it would do is go to the front-screen with the nook barnes and noble logo on the front. I could turn it on and off, but that was it. It charged. I tried to start packages on the device via adb but it said the system wasn't running. I could see processes system processes with ps.
I issued a reboot recovery command via adb. The Nook finally responded with something other than a reboot and it went into recovery and did a full factory reset. I thought I was in the clear. But no. It rebooted and went back to the logo screen as before. However, now I no longer have adb access.This might be because the factory reset turned off usb debugging. So now I can't access the device at all. Does anyone have any ideas how I might be able to proceed? I think the device is functional, but the bootloader is damaged somehow so I can't start Android on the device. Without adb access, I think it's effectively gone.
It's likely that you don't have any home application working.
Or maybe it's completely borked.
Have you tried holding various buttons on a power up to see if you can try recovery again?
The next worst case is just using the hardware console connection (inside the case) to see if you have a shell and what's going on.
For the old NST we had a whole setup to boot over USB even with a totally wiped out flash.
That hasn't been looked at for the newer iMX6 (vs OMAP) Nooks.

Can you point me to NST setup to recover over USB, I would spend some time to try to recover my Nook.
Thank you!
If you had just wiped out P1 you should still have recovery (on P2) just fine.
Do a restart holding the Home button down.
If this doesn't work you somehow managed to wipe the bootloader.
To get the USB HID bootloader to work would be a bit of a project.
There is the starting point of this tool: https://github.com/boundarydevices/imx_usb_loader
Anything that is written about USB recovery on the NST (which uses OMAP) has nothing to do with the new Glows (iMX6SL).
Hmmm, the Kindle Paper White 2 seems to have the same processor/ROM bootloader...
For what it's worth, here is an overview of the low-level MMC:
Code:

I was lucky!
Restart holding the Home button down made no difference.
Trying randomly, I observed restart holding the Home and Right Up buttons goes into fastboot.
I recovered P1 partition for which I had backup and my Nook is live again.
Many thanks!!!
imx_usb_loader would have taken some time to learn.
So you're stuck in the ROM USB bootloader?
To look into a solution I had to get the ROM USB bootloader to run on my Nook to test things.
I didn't feel like bricking the Nook, so that was out.
I disassembled the ROM bootloader and found the correct, erm, workable entry point in the ROM.
Code:
eBR-1A # go [i]<entry address>[/i]
Code:
iManufacturer: 0x01
0x0409: "Freescale SemiConductor Inc "
iProduct: 0x02
0x0409: "SE Blank MEGREZ"
So now I can play around with the ROM USB bootloader.

No.
After fastboot got enabled I booted nnglow3.img and then I recovered P1 partition with dd.
My Nook is like new
Thanks,
