Hi....i was going to format my shift and since i never used the vista recovery option from the bios i downloaded gparted and made a live cd usb and booted it up, deleted every single partition uncluding the hidden one that i could see and in total i had one big unallocated partitionless harddrive which i saved the changes and rebooted.
I then inserted a usb stick with windows 7 on it and proceeded to install, i created a new partititon and windows asked to create that 100mb system reserved and i then proceeded with the installation which took more than twice as long as it has ever done before.
Is this due to my gparted fiddling? Because at the second stage of installation, the unpacking of files it went quick and smooth up to 38% and after that slow as hell, unlike ever before during any version install...
And now that i finally had that part of the installation behind me it proceeded to automatically reboot for the final stage and when it did reboot after the RAM and basic BIOS tests it reported bad SMART status and i pressed F1 to continue and everything resumed as it should...
But I cannot find any settings in the BIOS to turn of the SMART checking so what can I do now?
Did i not delete the MBR? as I thought it would have gone with the partitions...
And why did the installation go so incredibly slow this time?
now I just got a Blue Screen & Ataport.sys message.
Could it really be such bad timing that the computers HDD has started to fail at the same time i deleted the partition or is this a software issue and not a hardware one?
What version of Windows 7?
I accidentally downloaded a RC/ Checked Debug version which had the same problems on an original untouched HDD.
If you are using correct version, then try repartitioning woth another tool liek acronis disk director. Format completely. Reboot, then re-partition , install windows 7 (RTM available tomorrow)
oh you sound a bit more optimistic than over at hd guru forum, check what they wrote when i published my thread over there:
http://forum.hddguru.com/htc-shift-recovery-partition-gives-false-smart-bios-error-t12907.html
IN MY INFINITE WISDOM, I replaced my build.prop with the one from a Motorola Xoom in an attempt to get Sketchbook Pro to show up in the market. Now my tablet is boot looping.
I backed the original up in the same directory, as build.prop.OLD. If I could mount system and replace the file with a PC, I'd imagine that the tablet would work again. How could I do that?
However, THERE IS ANOTHER COMPLICATION! I used the 'Acer Phone Disabler' app to remove the telephony drivers, which means that I cannot flash a rom or the tablet will brick. I'm not sure what this means for Nandroid backups.
The tablet has the leaked stock 3.1 rom installed, it's rooted, and it has Clockworkmod recovery.
Thanks in advance for any help!
Oh god.
I used ADB to pull my build.prop.OLD, renamed it to build.prop, and pushed it back. Now... the tablet boots up, and it shows the Android "Welcome" screen. Clicking the only button available doesn't work. It just highlights as if it is selected, and doesn't do anything when I lift my finger up.
I DO have a Nandroid backup from several weeks ago of the same rom, but from BEFORE I removed the telephony drivers. I am only going to try restoring it as a last resort; does anyone have any ideas? Remember, flashing a rom would result in a brick because I used Acer Phone Disabler. Is a nandroid backup safe?
Thanks guys. I'm really hoping this tablet isn't too screwed.
I'm hoping someone else chimes in here but I am under the impressing that the nandroid backup would override any changes you could make as long as you don't break recovery. As far as my experience goes if you had a backup of your current configuration you could do an "advanced restore" and only restore your "system"

Restoring just system worked! My homescreen is back to stock but all my apps are still installed, so I don't really care. Thanks a bunch, I was so worried.
COOL!!!
Glad I could help.

Help needed for a boot loop
Well as said in the video, i reuse an existing thread about bootloop...
I'm stuck in a bootloop with an iconia A500... but let's look at the steps that got me there...
The First mistake was to answer yes to my friend who asked me to connect his Vodafone k3565 to his iconia A500, but as i read Android was linux based and i did use linux a lot as a student, i didn't even imagine it could go wrong...
Tablet was stating to run :
Android 3.1
Bernel 2.6.36.3-00009-9dddf6f2
Build 4.015.05-EMEA-CUS3
i did root with iconia root 1.3
then added Busybox and a terminal program.
reboot, try a SU and could access the devices
Here is the second mistake... i should have wondered how to restore to normal state before starting, because i don't have any SD card that suit the device ( mine are normal sized ones, you know.. Stamp sized :/ )
Then i got to the thread
http://forum.xda-developers.com/showthread.php?t=1058846&page=7
and i used an usb key to transfer it to the device, but before applying the files i took a look to them and found 3 of them would overwrite actual system files, so i did a backup of them :
/system/build.prop
/system/etc/apns-conf
/system/bin/rild
and looking at the build.prop i saw differences in the values of the one on the A500 and the one in the package so i decided to get only the missing lines from the new system.zip file and add them to the original file
And here is the 3rd mistake, and i guess the reason of the problem : i did that merge on a windows computer, and i fear it did add those pesky CRLF at the end of lines, turning my build.prop into a build.prob(lem).
I'm not sure, as i didn't check before it was too late.
rebooted and... boot loop, with 1 times out of 2, the little android with yellow triangle and exclamaition mark.
Cried, runned in circles, then looked on forums to find a solution.
Reboot with Power+Volume gives :
"Erasing cache before SD update...
SD update cmd:recovery
--update_package=sdcard:update.zip
Booting recovery kernel image"
Then i get the android with gears for a few seconds, then below him is a bar like the one in the android store when you download a file, then half a second later, again the exclaimation mark.
I also tried plugging a keyboard to hit the home key...
( in fact two : Logitech G110 and trust easy scroll silverline )
no difference, maybe because those are gaming keyboards and they arent loaded soon enough by the tab, or maybe it crashes before keyboard loading.
Tried then to install ADB using post
http://forum.xda-developers.com/showthread.php?t=1155664
hoping i could use the USB cable to put the backup files back in place but when i plug the device into the windows host, it recognises an unavailable USB MTP device, whose properties say "Acer iconia tab a500" in the "signaled bus description"(translated from french display, may be something else in english)
I manually force added the Acer ADB interface, but both the devices are unavailable to windows, with a warning sign, stating "this device cannot start (code 10)"
"Adb shell" answers "Error:device not found",which is expected, as windows can't see the devices properly
the strange thing is that, with USB plugged from A500 to PC, the Android with exclaimation stays forever, while without the cable, the system boot-loops
so i'm at this point :
i have a boot looping device, and the backup of the modified files on an USB key, and no way to put them back on device.
I found on the forums a lot of different .imgs that could be put on the /system to reload the device but none with EMEA-CUS3. So if i overwrite the files, i can't go back
I read you need a SD card to patch the device but not all of them work...
And my only computer with a SD slot uses a big one, not micro one, so i also need an adapter to write on the sd card.
Is someone near me (belgium/postcode 4000) having a SD ward working with the device who could lend it or help me doing the job ?
else
i saw in a nearby store ad "Sigma SDHC 4Go" or "Sigma SDHC 8Go", with apparently an adaptor for a normal sized SD slot, can anyone confirm it works or it don't work for sure ?
else
Can anyone tell me an SD card know to work, and being sold currently with an adapter so i have a chance to find one in a store near me ?
Is there a way to create an update.zip that will only update the files i did overwrite ?
if not, has someone an image for the same system i have ?
Well... lots of questions, but i'm very worried, especially as the device is not mine and not working anymore atm.
-> update
Looking closer at the modem (Vodafone k3565) it has a trap that says "SD card" so i guess i won't need an adapter... still need the reference of a SD card known to work for the restoring.
[bump] and more :
this thread http://forum.xda-developers.com/showthread.php?t=834144
lists working SD cards, but don't tell with which device. i'd take the guess it applies to the iconia A500 and take the list to the shop to see if anyone is available...
Did you install the Acer USB driver, found here? http://www.acer.co.uk/ac/en/GB/content/drivers
You might need to go into device manager after installing and right click/update drivers on the tablet, then manually direct it to the Acer driver folder. That's what I did, then ADB worked.

The reason "some" SD cards don't work is down purely to formatting. Normally, reformatting them in an Android phone sorts it out. Not always, but normally. Don't worry about the GEN3 stuff too much, it's just regional variations anyway... More important to get the tab working again, no?
Yes i did ( on 2 different computers, just to be sure )...
and still the device is not recognised as "adb device".
Windows shows a "USB MTP Device"
Tried to manually add the "ACER Composite ADB Interface" and "ACER Fastboot Interface" to the installed peripherals, it shows with yellow exclaimation mark, never shows up running.
Without any useable answer about one week later, i did buy a Traxdata 2Gb SD card with adapter ( the cheapest i found with an adapter from micro SD to normal SD ) and flashed with the Emea_Gen3 ROM from http://forum.xda-developers.com/showthread.php?t=1113878.
Now the tablet works, but is telling me 4.010.42-COM-GEN1 instead of the previous 4.015.05-Emea-Cus3.
Seems to work correctly, so i go on with the modem connexion.
Hello !
I am feeling really down today after been trying to get my phone working again.
There is a huge problem currently, I am really annoyed that it doesn't work at all.
First thing, my phone won't start after update it just boot loops and never seem to end it.
First thing I noticed /boot, /cache /system and most things are gone, I can load up recovery but nothing more. I have no idea what happened but the whole image folder was wiped and I had to myself put in the CWM recovery.
I can't do an upgrade "again" as it will be stuck @ the unpacking part without starting it at all.
I been trying with 2.3 V2 and with B133(My stock rom I got).
If anyone has a solution that can solve this problem please help out if you could. Also if you are about to tell me get this and that, please most cases I haven't seen any of the Firmware roms in @modaco wiki links work. Means I can't download them, so if you happen to have spare copy please upload it and link it to me. I have been googling and looking through this section twice, nothing really worked out.
Thanks in advance !
If you didn't erase the .cust_backup partition which contain the image folder with all system' s .img files, then maybe it' s damaged. I had some problems with this partition before and when I checked it with windows check disk it repairs it and I had no problems from then. So, try this, and if you still haven' t any file on image folder, you can find the original folder on X5' s forums. Is definately here, but I don't remember where is the link and I don't gonna search it for you. If you cannot find it, you can allways reflash the original rom. If you fix the partition(if this is the problem), I don't think that you'll have problems with update any more.

Hello, thanks for the reply.
I have no idea about this .cust_backup partition and how I am supposedly to access it via windows. Also the thing you said about fixing partition within Windows, the check disk thing. I am not sure about that part either as I can load CWM and it can read the partitions but they are empty. Also there is nothing in this forums that contains original things, only way for me to fix this if someone have extra copy and can guide me on how and where to place the all needed files. I am pretty sure it's only things that are missing and I can't get a grip out of this.
So to sum up what my problem is.
I did an upgrade from 2.2 to 2.3 with official firmware, it worked out normally but after a reboot my phone became stuck in an endless loop, I can't do anything and it will not I repeat it will not allow me to "re flash" any firmware I tried so far, the 2.3 V2 and B133.
I am begging someone in this forum section, please if you have the knowledge about this problem care to help?
I can't get a refund out the phone warrenty is off and I do not have that much spare money.
Thanks in advance !
If you can get to recovery, wipe cache and data. It should be possible in stock recovery.
The cust partition has all the images for bootloader, recovery etc. You can get to it with the pink screen. Reformatting and then reinserting the images and files could help, but try that when nothing else works.
I can't give you good help via phone, but try wiping data first. Also, try if you can use some other sd card.

The most common things I have already done, but do enlighten me what this "custom" parition is. Because in windows I do not see such partition I see a removable partition which I have now added a folder called image with these containing files.
http://forum.xda-developers.com/showthread.php?t=1370960
EDIT ** Also regarding to first person who said about Windows partition manager. The thing is I see a lot of partitions and there is no labeling for them, might be because they are ext2/3 or even something else? In anycase I can't do so much I just find it really odd I have many duplicates and I am guessing that must be errors... Because I am seeing the main recovery partition which has no label too... its at 240 MB where 135MB is used. Lastly there is my internal SD card empty and healthy still I can't reach it within Windows if I do not mount it...And can't now without going into the android OS. I Have loads of free space "partitions I don't understand why they are there".

Thanks for helping out, it feels not good to have a half dead phone, it's still not solved :'-(
The .cust_backup is the mount point on android for this removable partition with image folder. In windows haven' t this name. I didn't mean to use the windows partition manager, just to use windows explorer, right click on the partition and choose properties, then tools and then check disk. Of course you can use partition manager too, but because as you found there are all no labeled other partitions there and is a bit confused.
As you mentioned, you found the original image folder and you replaced the files. Did you tried to do the update again after that?
Also you can see and the internal sd partiton, but you need linux system. This partition is not fat32, so windows cannot see it.

And I can't run the upgrade firmware, it gets stuck at first stage which is to unpack the the update.app thing.
It just stays like that not blinking and frozen.
Did you tried now that you have the original files, to go to recovery mode and wipe data etc?
Also when you try to do the upgrade do you have the device connected with the cable?
I had this problem once and I think that when I disconnected the cable(or maybe wasn' t connected and I connected it, I don't remember well), the proccess bar starts to moving after a while and the upgrade completed successfully.

You are not understanding me :-(, I have wiped already millions of times in millions of different ways just to get it work. And no, I don't have the device connrected when I upgrade, it won't work properly then, I have tried to wait for the progress bar to "start" move it won't happen the battery will die, and nothing happened.
I can't go in with normal Recovery mode, can only go in with CWM, the normal recovery mode is really small, I mean only 3mb, while the froyo version is 5mb. Now I am asking if you have the time to upload the image files from 2.3 V2, the ones in forums are for V1. Which I don't know might conflict.
Thanks again for trying to help me out, this is really frustrating to get it to work.
**EDIT**
I worked it out !
I think I understood what you meant, I did as you told I started first with pluggin in the charger forced it to upgrade and now it's upgrading, thank you so much dancer_69. I was going to go tomorrow to buy a new 2nd hand smartphone. But now I can save my money for other things !
**EDIT of EDIT **
I seem to have downgraded to B133, I will try now with B158 2.3 V2 again and hopefully it will work now.
Yes, wasn't clear because I don' t remember what I've done and solve it. But I think that I did it like you discribed too.
Anyway I'm glad that was helpful(kind of)..
And don' t give up so soon with smartphone' s bricks, I've faced brick kind of problems many times and if the device it' s not completely dead, there is something you can do. Maybe need more search or many tries(sometimes the same things) but at the end(and of course If there isn't a hardware problem) device can unbrick.
I've managed to softbrick my nexus 10 by trying to disable extra services (was getting about 1.5 hours battery life with media services running the processor 100% all the time). It worked wonderfully (no negative side effects, went back to 10+ hours with the screen on, or days on standby) until I reboot it and now it won't load past the moving colors (Android 4.4.3, unlocked and all that).
I have TWRP, I was hoping to backup everything possible via usb, but it seems it's incapable of doing so. ADB backup can't be done using TWRP since there's no unlock function (reaaal useful there, recovery mode that doesn't support backups) and adb pull fails if I try to pull everything since there are files and folders with invalid file names (who puts ":" in folder names? they should be shot), and I don't know specifically what to pull, I was just going to get everything put back what I found was missing that I needed. There's no room to do a backup onto the device, and since the N10 has to sd/microsd, well... Useless options are useless.
Is there anyway to just do a proper backup with TWRP over USB? Or is the "recovery" mode as useless as I think it is when it comes to backups? (I'm aware I can get the tablet back to working order if I disregard the data on it, this is a question about backing things up before doing so)
Edit: Also, I have a pro version of SkipSoft ToolKit, but unless you can actually load into the OS the toolkit can't do anything at all.
Just really frustrated with the lack of doing something as basic as copying files from one place to another. Been messing with this all morning.

Do you still need help? What about mtp mounting? You can pull * for a whole folder
Why not adb sideload a new rom?
I don't think I can MTP mount a Nexus 10, at least not in recovery mode. What I ended up doing was buying a OTG usb drive and making a backup to that. Problem was it split the tar over 4 files, which corrupted them (or at least made them not work with 7zip or tartool) fortunately I was able to get them to work with cygwin enough to get the files I wanted. I didn't want to sideload a new rom until I had backed up certain application data just in case it removed it.
All in all, had to buy a OTG usb drive (I would have just bought a cable but all the stores around here had was this "Dane 16gb OTG drive". So 20 bucks later I had the files I needed. Still annoyed that you can't do a ADB backup from fastboot or recovery mode, it seems like those would be the best places because no system files are in use, but who knows maybe the developers know something I don't.
In summary:
TWRP recovery cannot confirm a ADB backup over USB. ADB backups can only be done from the operating system.
TWRP recovery mode can only backup to OTG (if your device supports it, Nexus 10 does), but if the backup is larger than 2gb it will split the file and you will need some form of linux to extract it.
ADB cannot copy every file in recovery mode over USB due to certain file names being invalid for NTFS (this is probably not a problem on other file system types), this is problematic since the "pull" command has no skip option, it just fails when it hits one of these files.
Well you can easily flash latest rwrp that does well on my Linux mount internal storage but another solution is just flashing a rom with abd sideload and the'the back up from pc the content

adb doesn't work in fastboot mode, only recovery or Android itself.

1. I was just covering that you can't actually do a ADB backup unless you have access to android OS, in case anyone else came across this. (I didn't know when I started, and it took awhile to find it said concretely anywhere)
2. I made sure everything was mounted, the issue is when you send a backup command over ADB it says the "Now unlock your device and confirm the backup operation" message in terminal which you can't do from recovery mode on the device, thus you cannot do a ADB backup command over TWRP (or other recovery modes I'd imagine).
3. I should have been more specific. TWRP can do a backup to the device itself (built in storage), SD card (if your device has one and you mount it), or a OTG (on the go) device via usb directly to media like a flash drive. It cannot issue a backup over USB to a computer.
4. Completely agree it's a NTFS issue, but it could be mostly avoided by allowing files that error to be skipped or renamed rather than terminating the process. (I understand that's on the android devs since pull is made by them, and I doubt they would care to improve the command for a file system I doubt they use). Again I mostly included that so if anyone else is trying to figure it out they can stop looking for "a way" and just accept it can't be done.
Ultimately Khaon is right in that sideloading a rom would have unbricked it and I could have done the ADB backup then, I just wasn't sure how that might affect the app data storage so I was looking for a way to back it up before doing that.

I'd just 'tar' what I wanted on the device and then pull that with adb.
Yeah, I just had no idea what I wanted. I'm not 100% familiar with how the system stores application data, I figured if I copy everything than anything I "miss" after I formated it I'll be able to just research where it was and dig in the backup and pull it out.
Yeah adb sideload a rom will only affect system partition thus your data would not have been modified in any way. So you are done with your issue?

Yes, sorry for the slow reply. I've completed my update, just wanted to follow up on everything I did incase the information is useful for anyone else new to this like I am.
I am beyond ecstatic, after 3 months of research, trial and error, I fixed my tablet!!
I am pleased to announce a fix to the dreaded QDLOAD 9008 brick! I've written this tutorial on the one tablet experimented on (LG-V410 aka Gpad 7.0 LTE US ATT), but I'm pretty certain others may find this helpful to other qualcomm msm based devices.
Background: I maintain that I can fix anything I break so I did the worst thing and corrupted the data on my LG GPAD LTE 7.0 (V410). As a result the tablet wouldn't go into any mode, no lights, even when charging, no screen image or light, nothing. When I plugged it into my computer, it wasn't even recognized, windows told me the device was having a problem. After a little experimentation I got it recognized (held power while connected to power cycle) by the computer as "QD BULK". Further research I found some drivers for Qualcomm devices and got the computer to recognize it as "QDLOADER 9008". I thought this was great news but from there got no where. I tried qpst, qfuse, hyperterminal, LG B2C, LG SUPPORT TOOL, EFS Professional, miflash, blankflash, etc... everything I tried got me nowhere. After 3 months, It is now fully operational and apparently CARRIER UNLOCKED, talk about a pot of gold at the end of a rainbow!!
WORD OF WARNING: This is not a simple matter, 9008 most likely means your Grand Partition Table is corrupted, and the poor thing doesn't have a clue how to function. My method is NOT GUARANTEED in any way, I will not be responsible if you turn your paper weight of a device into permanent paper weight or half functioning paper weight etc...PROCEED WITH CAUTION, this is not for the feint of heart nor a simple fix!! You've been warned!
PreRequisites:
-Windows (for expanding the KDZ) (there may be a linux alternative to LGFirmwareExtract)
-Linux and some basic experience with dd and navigating the terminal (I used ubuntu) --(again, nearly everything I'm about to explain can probaly be translated to another os.)
-KDZ for your device. http://forum.xda-developers.com/g-pad-10/general/kdz-lg-g-pad-7-0-v410-t3224867
-Replacement aboot and boot (see attached)
-KDZ Extractor ---http://forum.xda-developers.com/showthread.php?t=2600575
-TWRP http://forum.xda-developers.com/g-pad-10/development/recovery-twrp2-8-5-0lgv400-410-t3049568
-Fasboot and ADB http://forum.xda-developers.com/showthread.php?t=2588979
-A modified rom like Cyanogen mod etc... http://download.cyanogenmod.org/?device=v410
-16GB microsd card + a way of directly writing to it (i.e. usb card reader etc..) a second one is helpful but not required.
-Most important, Patience, beer, more patience, and more beer...
To teach a man to fish, some pertinent understanding: First thing to understand is how your main board works. Personally I disassembled my device and cross referenced every chip to do this, Good news is you don't have to. When power goes to the device, the SoC (system on a chip) looks to built in storage media for booting instructions (think low level here) and that in turn fires up everything else and then loads your kernel etc... You may be aware, there are two different types of computer systems out there, the old method used a BIOS, and the current uses UEFI. Older machines, when power was given to the system, the BIOS was responsible for firing up peripherals and finding the bootloader etc... UEFI (Unified Extended Firmware Instruction) however, relies on firmware on storage media to do all that.
For example, an x86 PC with a bios, when power is given to the board, the bios runs the show, testing equipment and waking up devices, then when it's ready, it looks to external media for a little magic byte at the end of the first sector of that media to indicate that it is bootable and in turn will boot (let those instructions take over). This style of booting media is called MBR or Master Boot Record.
Modern machines and most mobile devices use GPT or global partition table. There are quite a few advantages to GPT one primary being the possibility of many many more primary partitions, (MBR was very limited). The GPAD 7 LTE has 34 partitions to put things in perspective. When your device is stuck in 9008 mode, it is because it doesn't have a clue how to boot, most likely your GPT is corrupted. Fortunately, at least with the Gpad 7.0 this information does not have to be on the onboard internal memory chip. For this fix we will be constructing an sdcard to have all this info to get into a mode capable of writing to the emmc.
Without Further Ado, Here are the steps:
]PLUG THE TABLET INTO A CHARGER while you do the following (you may think it's been off and fully charged, but in reality it's probably been trying to boot over and over again while looking lifeless)
1.) Get the KDZ for your device (stock firmware)
2.) Extract the DZ using LGFirmwareExtractor
3.) Extract all the .bin files from the DZ using LGFirmwareExtractor
3b.) V410 US LTE ONLY - Replace aboot and boot with the files I attatched --I was fortunate enough to back them up before I hosed my tablet and they proved invaluable as the ones in the KDZ I linked to were causing strange graphic issues.
4.) open a terminal in linux and dd the sdcard with the file you extracted called "PrimaryGPT...."
I.E. "sudo dd if=/PATHTODZFILES/PrimaryGPT_0.bin of=/dev/sdx" (BE CERTAIN of the of= path, you can find yourself with more problems if you get that wrong) (run "sudo fdisk -l | less" first to verify what your sdcard's path is.)
This is where it gets tedious...:
5.) Do some hand stretches and start charting all 34 partitions on paper. Your sdcard is now partitioned with GPT and you need to know the name of each partition and its path. I.e. ("Partition name: LAF Located at /dev/sdXx")
6.) now for the fun part: dd every .bin to the corresponding partition EXCEPT: laf.bin and any of the system_xxxxx.bin files. (laf disables fastboot and the next step will bring you to a useless LG firmware download mode)( I.e. sudo dd if=/PATHTODZFILES/laf_xxx.bin of=/dev/sdXx) If some fail out, don't fret too much, I'm currently uncertain which ones are required and don't feel like corrupting my tablet again to figure that out. If the next step doesn't work you may need to revisit this step and ensure everything was accurate. It's easy to write down the wrong location for a partition and throw everything off
7.)Unmount your sdcard and put it in the tablet
8.) Press and hold power and volume up...If all went well, there is suddenly life to your paperweight!! Congratulate yourself and prepare for more fun... If nothing happened, revisit the above steps, more than likely something got flashed to the wrong partition.
9.)Now that you have fastboot, plug your tablet into the computer and use the following command: "fastboot boot TWRP.img" (or whatever the name or path is for your downloaded TWRP image.
10.) You should now be in TWRP and now your device is ADB ready, we are close to the home stretch...
11.) Now we need to load up an sdcard with all those dz files (except for laf and system images) and the custom rom like cyanogen mod. (if you only have the one sdcard you can unmount it and remove it while the table is in TWRP...crazy right?, if you opt for this, reformat the sdcard to ext or fat or whatever you please so the tablet can see all the bin files) Then put the sdcard into the tablet. You may need to remount the card in twrp before proceeding...
12.) Now from your computer type the following command "adb shell".
13.) now just like you did with the sd card dd PrimaryGPT_0.bin to the internal memory card, with the following command: dd if=/sdcard/PrimaryGPT_0.bin of=/dev/block/mmcblk0
14.) Grab the paper you wrote all the partitions down on and start doing the same thing you did to the sdcard to your tablet. You'll adjust the following command accordingly: "dd if=/sdcard/PARTITIONNAME.bin of=/dev/block/mmcblkpX (X being the partition number)
(again skip all system bin's and laf_xxxx.bin. Flashing laf disables fastboot on LG devices.)
15.) now time to install your custom rom, go through the prompts, clear your cache, and delvik cache and choose power off.
If all went well, you now have a tablet again, that's unlocked too!!!!! If not, don't lose faith, revisit the steps and ensure you didn't mistype or overlook something, this is so tedious it's easy to do. For instance, if you mistype your of=xxx it will create the file instead and give no error.
Post with your success stories, questions or difficulties and I'll try to help.

UPDATE/WARNING: Do not at any time under any circumstances dd directly from your host computer to the internal memory on your tablet, only do this via the asb shell. This may render a mode that I have not yet found a fix to, I will be working on it soon but from initial observation may be more complicated then the above instructions. With any invasive hacks like this tutorial there is always the possibility of making matters worse, so exercise caution and patience.
Quick Update/Revision : I am actively experimenting with this device and wanted to share that if your sbl1 and sbl1b partition is corrupt I have confirmed it will also cause 9008 mode. Therefore, it may be best to determine if the table is corrupt (try "parted /dev/block/mmcblk print"), and if not instead of wiping rewriting mmcblk0 try restoring sbl1 and sbl1b first. The V410 boots in the following order from what I can tell slb1->aboot->boot->system. So far I haven't found a downside to my prior instructions but to be less invasive just in case it might be wise to try this amendment.
I know my grand partition is corrupt, because after doing fastboot erase, basically everything, it came up as /dev/sdb. In a panic, I had deleted all the partitions, so now obviously my emmc storage is one big formated 16gb HD that cannot be seen in windows or linux no longer.
I just tried your method, found this post by doing a google search for:
sudo dd if=PrimaryGPT_0.bin
Had been doing just this, including the laf and many other ways. Am still getting the same thing though when putting the sdcard in the tablet, shows a 0% battery.
with the sdcard in the tablet I do get:
Bus 003 Device 063: ID 05c6:f006 Qualcomm, Inc.
Then after a few minutes, leaving it plugged into the USB I get:
Bus 003 Device 058: ID 1004:61a1 LG Electronics, Inc.
Also, with the sdcard in I do get KDZ_FW_UPD_EN to start updating but then get a perimeter error.

Ive seen the exact mode you are referring to. Three possibilities:
1.) unplugged, hold down the power button for 30 seconds (or less if fastboot comes up)
2.) your sd card does not have all the necessary partitions to boot (which i just confirmed are specifically rpm, rpmb, tz, tzb, sbl1, sbl1b, PrimaryGpt(has to be done first), aboot and abootb)
3) They didn't dd quite right. from my active testing Ive found if you script the dd'ing it doesn't quite flash right, unless you add a delay after each step.
Its actually a very good sign you are seeing the 0% battery logo, sounds like you are almost there. Let me know what happens. Ill be happy to help guide you. Ive dedicated my v410 as a dev board so Im constantly running tests and reverse engineering it.
The 0% only shows up with the sdcard in, after I remove it, nothing. Tried wall charging it all night, that did nothing.
My theory is that if there was some way to mount the raw emmc and dd the primarygpt.bin to the raw emmc hd then the rest would be not problem.
I deleted the original EMMC partitions in gparted under linux after doing an erase fastboot -w laf, system, etc... something like that. After that the tablet did not show up again in gparted as soon as I unplugged it.
Right now I'm zero dd'ing my 16gb sd card, dang dd'ing seems to glue the partitions to the sdcard, If I try to fdisk the sdcard or delete the partitions using gparted, as soon as I dd the primarygpt.bin the old files reappear. Need to start fresh with 0s to the card.
In windows I can actually install specific lg drivers while in qualcomm hs_usb 9008 mode. The interesting thing with the sdcard in I can install the LG Android Net USB serial driver, which will not work while in 9008 mode.

The 0% comes up when your sdcard is inserted because you are close to getting it done. You're going to have your computer running all night on the zero'ing but I can assure you that will be in vein. The whole point of this tutorial is so you can get into a mode in which you can flash the emmc. I can tell you are a little lost in the steps so pm me and I'll help you out. Also a word to the wise, you can try all you want with windows and the 9008 drivers, but seriously there is nothing out there specific to the v410 thats going to help you "engage" the 9008 mode. Not being stubborn I've just literally tried it all. If it's any credit I am clinically OCD. I can't sleep till I figure things out.
Finally, I see a hope is shining here!
I bricked my LG VK810, when I was trying to flash twrp, I refered to v500 pad instead and I flashed wrong img files (aboot, boot, sb1, sb2, sb3, tz & twrp.img) "only those 6 files" so I only need to replace those with the correct files, which I downloaded now.
I do not have Ubuntu, however I have CentOS, which i have not used for couple of years, so I forgot how to use it. also do I still need to use the LG Firmware Extractor?
please help

I am not certain exactly which partitions have to be flashed, the attached note I made was from what I can tell so far. I was simply noting that it may be best to try one partition at a time vs doing them all at once, it is at your own descretion. So as far as listing the partitions, I'm not familuar with the centos distro but in Ubuntu it is something to the effect of fdisk /dev/sdb -l or gdisk /dev/sda then p. I hope that answers your question, If not please be more specific to your exact question.

Thank you very much for your response, I am sorry I have never flashed partitions before, sbut I noticed gparted is not on CentOS, so I downloaded Puppy precise Linux as I was able to find gparted and I tried using it as shown in this video, https://www.youtube.com/watch?v=6z1Tu9l8WNc
But I am confused now about how big and what are the formats for the 34 partitions which need to be created?

Flashing PrimaryGPT_0.bin will automatically create the partitions. Flashing the individual partitions will give each partition the data needed. There should be no need to manually create partitions, if no partitions show up in gparted, the problem goes back to primarygpt, as that is the partition table.

I'll be honest and blunt, if you do not have experience with linux, a simple keystroke mistake could wipe your entire computer. I can't in good conscience recommend touching dd if you're not familiar with it. Not trying to be condescending or anything just really dangerous tools we are working with here.

Issue
Hello, I've successfully followed the tutorial until step 9. When i flash TWRP it reboots and comes back to the fastboot screen.
If I hold the vol+ button when it is booting, the download mode screen flashes for a second and then it comes back to the fastboot.
I haven't been able to to anything else and would be very grateful if someone could help me with this.
Apparently there is no bootloader so it is stuck
I attached a picture of my screen
LG G Pad 7.0 V400
Is there a way to unlock Qualcomm 9008 from LG V400?
Finally my dead tablet went into fastboot mode.
Except windows cannot find a fastboot driver and fastboot command can't locate the device either. Any suggestions?
