I converted back to ext3 with BackToEXT3 by Paul but didn't realize I needed to restore a new image right away. Instead I shut down the phone to use SmartFlash. Smartflash doesn't find the phone though and the phone doesn't boot anymore (ie. no logo, no recovery, no nothing).
If I try NVFLASH to restore the phone I get the following error message:
failed executing command 16 NvError 0x120002
command failure: create failed (bad data)

My O2X is laying as dead weight on my bookshelf at the moment. I think today I must send it in for repairs before it (or me) gets suicidal. If anyone has any advice to offer on this problem I will send you gingerbread cookies.
You should ask Paul from MoDaCo. Either via Twitter or his forum.
Friends..i am beginner+ to this forum.. i got stuck in a bad problem(bootloop) below. Please help me to save my O2x
Thanks in advance and appreciate all your help ..!!
Reason for bootloop:
===============
Flashed temasek CM7 and it worked perfectly.
Then flashed Horsepower 2X extreme kernel and it came up and worked.
Then when i re-started the phone, it enters into BOOTLOOP and stuck there forever.

wiped cache/data/david cache... and then flashed temask cm7 ...it again bootloops.... e:/can;t mount cache..
I tried with nandroid backup that i had taken during CM10..i didn't work out and bootloops...!!
Is there any possible solution to this ?

Power it off, remove battery, hold vol- and insert USB cable.
If it shows something about SW Update on the screen, then just smartflash a stock ROM, then start again. Saves dicking around.
sw upgrade boot doesn't work either
Thanks for ur reply Rusty...!!
I tried SW upgrade boot also, it didn't work .. flashes lg logo and turns off... if i keep on holding vol - button, it blinks again and again.
I think i bricked my phone.. Internal sd-card /emmc,/cache)is not recognized/mounted.
It's pretty much impossible to brick it. NVFlash will fix it.
When you tried, was the phone plugged directly to the motherboard or through a hub/front ports? Direct is best.
Yes, i tried through serial port and tried with other port also, didn't enter S/W upgrade screen.. (Mine is Dell XP15 - win7 )
Have installed latest LG drivers and nvflash drivers are latest and showing up in device manager also..!!
Through nvflash it stucked - bad data or hangs for hours..!! (have tried changing data cable too)

Before giving up, borrow some time on a desktop computer, connect directly to a port on the motherboard, try again. Use a USB2 port.
Re- Use a USB2 port.
When i connect to usb3 ports, it detects APX device and 'NVIDIA USB Boot-recovery driver for Mobile devices' appears in device manager.:angel:
But when i try usb 2 port, it prompts as unkown device(usb device not recognized) -[ Lg drivers work with usb 3 ports] and not able to proceed further.
I have always used usb3 ports for rooting O2x and all- it went fine, should i still need to debug on usb2 unknown device issue ?
Nvflash worked..enters sw upgrade screen
Friends, nvflash works successfully and files sent successfully and phone enters S/W upgrade screen.
If i release usb cable, put the battery and power on with vol-down, it again enters into CWM and not S/W upgrade screen.
Need to know what are the next steps to do , also what are the files that i have to put in sdcard ?
addition to this.. adb also working..
Friends,.. now nvflash works and i am to do some basic ADB commands also..!! [Smartflash not working - due to phone not entering s/w upgrade]
C:\Users\Senthilnathan\AppData\Local\Android\android-sdk\platform-tools>adb shell

Need your help - What are next steps i should do ? What are the files i need to download to make my O2x work? :fingers-crossed:
Well if you can ADB in recovery, I guess you should download a ROM, stick it on your SD card and flash it.
OR
Remove battery, hold vol down and plug in USB cable to get the S/W Update mode, then you can smartflash.

Waiting for bootloader to initializer
Hi vsnstarguy,
I have a situation like yours. My device is dead and nothing shows on screen. I've tried that methods, nvflash, smartflash but my device is realy dead and I got the same status like you:

Hekp me!
I've opened a thread about this but nobody could help me yet!
Thing is, most people manage to get passed that point. If you've plugged directly into the motherboards USB ports, have you tried another computer?
@cl06 - nvflash and adb works..!!
@cl06 - Dude, is you phone p990 or p999 ? you seem to be trying with p999.
Nvflash p990 correctly, it will work.. (got this from Rusty thread)
or navigate it to your nvflash folder for p990 and try below command--
nvflash --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 14 cwm-int.img
In above nvflash command - after download for p999 it will be 5 for p990 it will be 14.
For some intermittent issues, i changed usb cable and now nvflash works but im still in bootloop for which our friends here will help us
I have LG Optimus 2X P990 which was working normally till last two months.
In last two months it get slower and slower and now wont turn on and wont flash.
When I connect it to PC - PC recognize it and I can start flash process, but it always stuck
at the same step :

TF701T NvFlash Unbrick Solution(tested)
(continue of the threadhttps://forum.xda-developers.com/showthread.php?t=2655888)
Charge tab before unbricking.
Connect tab to PC.
If your tab not started already in APX mode, then run APX mode by pressing button combination Vol+ and Power.
Insall drivers from "usb_drivers" if needed.
If there is a problem with the installation of drivers, use Google to search- how to install unsigned drivers.
When device installed correctly run "tf701t_flash.bat".
If flash process interrupts with error like ...read\write error..., then probably EMMC memory chip is damaged and need to replace.
If flash process complete, then we ready to next step.
Prepare fat32 formatted microSD card.
Download from ASUS site update package.
https://www.asus.com/us/Tablets/The_New_ASUS_Transformer_PadTF701T/HelpDesk_BIOS/
It _MUST_ be Version V10.14.1.47, SKU(region)- of your choice.
The downloaded file will look like **_epaduser_10_14_1_47_UpdateLauncher.zip
There will be another archive inside that archive.
Extract it, and rename it to t4_sdupdate.zip
Put t4_sdupdate.zip in root of microSD card.
Insert microSD card in tab, then start tab in recovery mode by pressing Vol- and Power key combination.
Follow onscreen instructions to complete recovery process.
After all you tab must be restored to factory state JB Android.
Now you may update firmware version using OTA or sdcard.

What is this? A covert ad campaign for Mega? How about hosting the file somewhere that does not force you to download an app, open an account and all that cr***? I'd be really curious to see the code, but not like this.....

Where did you see the ad or need to register, or requirement of install the program for downloading?
Just checking in IE and FF.
I see a big red button- "download", no ads, and no requirements.
Ok, for those who have problems with mega.nz added a mirror for download.
TF701t - Hard Reset Fails ...
Dear Community,
I wanted to hard reset my TF701t to delete my data and give it to another one.
But now it stucks in "deleting data" ... that endures a minute then a dead android is on the screen.
When I want to reboot it, the hard reset comes again and want to delete everything, but the dead android is coming back :/
I can't go in Recovery Mode (Volume-down + Power)
Connection to APX works but, see pic below ...
I don't know what I could try anymore ...
Hope somebody have an idea.
Best greetings,

Link to the picture is broken, so we cannot see what result you got...
What's your situation: Bootloader unlocked? Custom recovery? I guess not since you get the dead Android?
link to screenshot ok.
as i can see- problems begin after trying access to EMMC chip.
"Taking backup of EKS"
unfortunately with 90% certainty i can say that the EMMC chip damaged.

Hello Mr Bin, registered an account just to say thank you...
You have no idea.. was helping a friend to update, but the guy who sold it(tf701) had bought it from different region and turned it to US, so we ended up hard bricking it.
Long story short, we hard bricked it.
Thank you for your hard work in making the fix, and a big THANK you for sharing it...
Perfect fix, its better than before because it got updated to .47 (we couldnt update, no OTA no manual, too old version for custom recoveries)
Again.. thanks :good::good:
Thanks.
But, after clicking to RCK, shows Android with blue procesing line and after few seconds android with open door and red triangle !. After few minutes bootloop....nothing more.
What can i doing again?
Wow! It's back!
Hi.
First of all: Thank you very much! I was sure my tablet was a goner... It is actually back. One tip I'd like to add: I had to try around a bit to get into APX mode. But essentially I just had to connect the tablet to my PC and then push "Volume up" and power at the same time - and ignore that the screen did not light up ...
Again: Thanks a lot!
Mr.Bin,
You have resurrected my TF701T! Thank you SOOOO MUCH! You are an actual genius! Thanks!

I would be very thankful for any information you could read from this. Just would like to know if i even have a chance of getting it back on.
So, I was running fine with CROMi-X KitKat, but wanted to upgrade to Marshmallow (to install sw not supported in KitKat), so decided to try KatKiss 6.0. It's been years since I've played with flashing ROMs, but I did a little reading to refresh my memory. Then I rebooted into recovery (ClockworkMod), backed everything up, then wiped everything, formatted /data, and tried flashing the KatKiss zip file. At that point, it just sat there forever at the ASUS logo screen:
I've tried several times to boot back into recovery by holding the Vol+ and Power buttons, but it either doesn't boot, or boots to the above screen. I've connected it to my Mac w/ the Android SDK Platform Tools, but adb doesn't see any device listed. [I've got an old Windows laptop (XP?)] I could use if it will do something the Mac can't.]
Any advice on how I can save this tablet?
This method can be apply to tft300t?
Hi! What a great thread! After lurking on this forum for many years, i've registered to expose my issue with an old tf701 that was given to me by a friend. He say me he installed esexplorer and deleted file to clean space. Next day he rebooted and never been able to boot system. Now tablet is in bootloop ending with blackscreen and backlight on. Im able to open in fastboot and talk with minimal adb and fastboot. RCK update ending with fallen robot, Wipe data/cache ending with fallen robot. APX mode also working and ive run mr.bin's Nvflash unbrick tool with this result:

Hello. These commands for nvflash make a backup and installation of the system.
REED

@nvflash.exe --blob blob.bin --bl bootloader.bin --read 9 recovery.img --read 11 boot.img --read 12 system.img
@pause
WRITE
@cls
@nvflash.exe --blob blob.bin --bl bootloader.bin --download 9 recovery.img --download 11 boot.img --download 12 system.img
@pause
Thanks mr.bin for a great tool
Important information who uses nvflash!
3 files (ABTxxxxxxxxxxxxxxxx.bin, EKS_xxxxxxxxxxxxxxxx.bin, PER_xxxxxxxxxxxxxxxx.bin, which are created after running nvflash, must be flashed again. Otherwise, it will be impossible to unlock the tablet again and the serial number will be lost. Save in a safe place and then rename the files to EKS, ABT, PER.
To do this, create a second file with the bat extension. In a text editor, type these lines
Code:
nvflash --wait --blob blob.bin --bl bootloader.bin --download 7 ABT --download 21 EKS --download 18 PER --go
If these files are saved on the unlocked tablet, then after their firmware unlocking will be restored.
Also, using nvflash, you can resize partitions, flash a bootloader with file system markup, recovery.
There is no way to load an unlocked bootloader in this process ??
Thanks to @Jirmd for letting me use his post as a reference.
Original post: https://forum.xda-developers.com/nexus-7/general/unbrick-nexus-7-tegra-3-device-t4078627
Alternative Method:
1. https://github.com/tofurky/tegra30_debrick
2. https://forum.xda-developers.com/t/...-without-another-n7-or-tegra30-device.4305955
(Both methods do not require another Nexus 7)
Requirements:
1. Linux-based OS (I use Ubuntu 18.04)
2. NvFlash and Wheelie (You can download the Linux version down below)
3. A USB cable (A good and sturdy one)
4. Nerve of steel lol
5. Must have APX driver installed.
6. Another Nexus 7 (Ask someone that have it or ask me)(MUST BE ROOTED AND HAVE TWRP RECOVERY INSTALLED)
7. ADB (platform-tools)
1. DUMP SBK VIA USB
Step 1: Download fusee-launcher for Nexus 7 from this link and extract it to a folder:
http://www.mediafire.com/file/sgwsa79idk24z8u/fusee-launcher-n7.zip/file
Step 2: Open a terminal inside of the folder then type:
Code:
sudo apt-get install python-usb python3-usb
Wait for it to complete. After that, type:
Code:
pip install pyusb
Step 3: Connect your device to a USB 3.0 port (REQUIRED). You can check for connection using "lsusb". There must be a "NVidia Corp" in the list.
Step 4: Type:
Code:
sudo ./fusee-launcher.py –tty dump-sbk-via-usb.bin
Something like this should appear:

Search for the line "hello, world" inside of your log. It looks like this in this example:
Code:
hello, world
b'e57de3bab6cb499d874d5772cb219f0101042c20'
The last 8 characters are not your SBK. This is the first 8 numbers of your Device ID. Delete this and delete the b' at the start and also the ' at the end.
The result should look like this:
Code:
e57de3bab6cb499d874d5772cb219f01
Congratulation, you have successfully dump your device SBK via USB.
2. GETTING YOUR CPU UID
Step 1: Download Wheelie and NvFlash then extract it to a folder.
Step 2: Download this broken blob.bin file (REQUIRE)
http://www.mediafire.com/file/32cxvjv2wajokqf/blob.bin/file
Then place it inside of the Wheelie and NvFlash folder.
Step 3: Open a terminal inside of the folder then type:
Code:
./wheelie --blob blob.bin
After that, something like this should appear:
Code:
Wheelie 0.1 - Preflight for nvflash.
Copyright (c) 2011-2012 androidroot.mobi
========================================
[=] Chip UID: 0x98254853062001158
[-] Incorrect SBK or SBK type selected. nverror: 0x4.
Search for "Chip UID", remove the "0x" at the beginning. The result should look like this:
Code:
98254853062001158
Congratulation, you got your chip UID
3. GENERATE BLOB FILES USING ANOTHER NEXUS 7
Step 1: Download MkNvfBlob from this link:
https://github.com/GeorgeMato4/nvcrypttools/blob/forN7/precompiled/precompiledN7.tar.xz
Note: Extract this to your Nexus 7.
Step 1.1: Reboot into TWRP recovery.
Step 2: Open a terminal inside of you ADB folder then type:
Code:
adb shell
After that:
Code:
su
Type this command after that:
Code:
mkdir /AndroidRoot
Last one:
Code:
cat /proc/cpuinfo > /AndroidRoot/cpuinfo
Pull the cpuinfo file using this command:
Code:
adb pull /AndroidRoot
Note: You could copy your cpuinfo file to your PC using MTP (IDK how to do this so search Google lol)
Open your ADB folder and there should be a AndroidRoot folder with a cpuinfo file inside of it.
Open cpuinfo using a Text Editor. Something like this should be inside:
Code:
Processor : ARMv7 Processor rev 9 (v7l)
processor : 0
BogoMIPS : 1993.93
processor : 1
BogoMIPS : 1993.93
processor : 2
BogoMIPS : 1993.93
processor : 3
BogoMIPS : 1993.93
Features : swp half thumb fastmult vfp edsp neon vfpv3 tls
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x2
CPU part : 0xc09
CPU revision : 9
Hardware : grouper
Revision : 0000
Serial : 015d4a5f202c0401
Replace the Serial line with your Chip UID.
After that, place the cpuinfo file back to the /AndroidRoot folder on your device using this command:
Code:
adb push AndroidRoot /
After you are done, don't close the ADB windows.
Step 3: Download bootloader.xbt:
https://github.com/GeorgeMato4/nvcrypttools/blob/forN7/bootloaders/bootloader.grouper.XBT
And BCT for your device:
https://github.com/GeorgeMato4/nvcrypttools/blob/forN7/bct/n7.bct
And copy these two files to the /AndroidRoot folder on your device.
Step 4: Type this command on the ADB windows:
Code:
cd /AndroidRoot
After that, type:
Code:
chmod 777 ./mknvfblob
After that, type:
Code:
./mknvfblob -W -K <your SBK> --blob /AndroidRoot/test.blob --bctin /AndroidRoot/n7.bct --bctr /AndroidRoot/testr.bct --bctc /AndroidRoot/testc.bct --blin /AndroidRoot/bootloader.grouper.XBT --blout /AndroidRoot/test.ebt
Wait for it to do its job.
After that, go to your /AndroidRoot folder and copy all the file that just got generated (testr.bct, testc.bct. test.ebt, test.blob) to your PC using the adb pull command on Step 2
Congratulation, you have successfully generate blob for your bricked device.
4. UNBRICK YOUR DEVICE (The fun part )
Step 1: Boot your bricked device into APX mode either using Power button or Power + Vol UP.
Step 2: Open a terminal inside of the folder where you place your NvFlash folder (move the blob file inside of that folder, all of them)
Step 3: Open a terminal inside of your Wheelie and NvFlash folder. Type:
Code:
sudo ./nvflash --bl test.ebt --bct testr.bct --blob test.blob
If you got this command:
Code:
command error: no command found
Then try this one instead:
Code:
./nvflash --setbct --create --configfile <your flash.cfg> --bl test.ebt --bct testr.bct --blob test.blob
If you got the NvError, its fine.
Something like this should appear (the first command):
Code:
Nvflash v1.13.87205 started

A Google Logo should appear on your device screen with the text "Battery is too low" on the upper left corner. Unplug the battery and replug it. After that, plug it into a wall charger for atleast 4 hour.
Step 4: Unplug the battery and boot into APX mode again using the button combination.
Step 5: Type this command while holding down the Vol DOWN button:
Code:
sudo ./nvflash --resume --download 8 boot.img
Replace "boot.img" with your ROM boot.img file. If you download another boot.img that isn't for your ROM, your device will bootloop.
Step 6:
Type:
Code:
sudo ./nvflash --resume --download 4 bootloader.img
Replace "bootloader.img" with your bootloader.img file name (You could get it inside of the Factory Image)
And after its done, your device should technically unbrick now. But I still recommend you re-flash stock ROM.
Step 7: The final step
Boot into your OS using the command below:
Code:
sudo ./nvflash --resume --go
If your device boot back into APX mode, maybe you have done something wrong. Try again.
If you got a Google logo on your device then congratulation! Your device is now unbricked.
Note: If step 7 didn't work, try booting this recovery image using this command:
Code:
fastboot boot flatline_grouper.img
Link for the recovery image is in the "Links" section.
Note: To get into Fastboot, add the "--go" line at the end of the command in Step 5
Code:
sudo ./nvflash --resume --download 8 boot.img --go
HOLD DOWN VOL DOWN while doing this command, you should get into fastboot at
After you are in the Flatline recovery, navigate to the "Advanced" section using the VOL buttons. Select it using the POWER button.
Select the "wheelie" at the end of the list.
Select "I agree".
After that, select "Step 1: Flash AndroidRoot.mobi custom bootloader." IGNORE Step 2 because it won't gonna work anyways.
Your device should reboot and the Google logo should appear, that means that your device is unbricked.
Note: If you wanted to flash stock ROM, open the "image-*******.zip" inside of the factory image and open the android-info.txt file. Edit the "require-bootloader" line to "4.13". After that, it should work.

Download the Factory Image for your Nexus 7 incase you want to re-flash stock ROM (nakasi or nakasig): https://developers.google.com/android/images#nakasi
That is. If you need any help, message me.
Update: After a few days of troubleshooting, fixing and updating my post, it seems like the step to unbrick your Nexus 7 2012 may depends on how did you brick it, what OS version you are running or the condition of your device. So you may have to "think outside the box" sometimes in this guide.
Update #2: Some helpful advice from @Jirmd with some minor change:
When you get this error :
Code:

Probably you have broken your internal storage!
You can probably flash:
Bootloader image (bootloader.img)
Kernel image (boot.img)
Recovery image (recovery.img aka TWRP)
But you CAN'T flash a new system via TWRP or fastboot, because the bootloader or the recovery was unable to connect to the partitions table.
You can try this command to erase bad blocks:
Code:
./nvflash --resume --configfile flash.cfg --obliterate
Reboot to APX mode and try the above command again.
But, broken internal storage is pretty much unrepairable.
There is some possibility of disassembly your device and overheat your memory IC, but this method is not easy and need more technical skill.
And in my case this did not help.

In my case, this command also gives me the nverror 0x4 but it also did something to my Nexus 7 as it was required for the next step.
Update #3: Updated the guide and removed some unessacery steps.
Update #4: Updated.
Hi, enderzip...
I've been keeping track of the recent developments regarding bricked Nexus 7's, APX mode and nvFlash, here on XDA. There's currently quite a few threads on this topic.
As I understand it, you've been motivated by a desire to recover data from your bootloader bricked Nexus 7. So my question is simple...
'Have you been successful?'
Have you actually resurrected a bricked Nexus 7 with no functioning bootloader AND with no originally created flatline wheelie blobs?
If so, you have done what I thought could not be done! I tip my hat to you, with your tenacity and your technical understanding of the complex issues involved.
If I had a Linux system myself, I'd be half-minded to dig out my old Nexus 7, deliberately bugger up the bootloader, and follow your instructions for the sheer technical challenge!
--------------------------------------
Some general thoughts...
The Nexus 7 is old (c.2012), and likely not many people use it anymore, but that's not what's important here. What is important is the persistence, the huge technical ability, and the sheer bloody minded refusal ~ by some ~ to let their Nexus 7 die... to go into what the poet Dylan Thomas called that 'good night'...
"Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light."
https://poets.org/poem/do-not-go-gentle-good-night
And in so doing, mayhap enderzip and others, have provided potential clues for other devices, other hardware, other phones or tablets, when faced with similar hard brick problems. One can but hope.
The above post by enderzip is technically way beyond me, and I have no immediate use for it, but it's a fundamental distillation of everything XDA stands for - namely, experimentation and creativity.
It's basically, amazing!
Thanks enderzip
Rgrds,
Ged.
Hello Enderzip,
Thank you so much for this very good an detailed tuto.
I followed cautiously your instructions but I am blocked @ step 3.
The command "mkdir /AndroidRoot" returns "mkdir : '/AndroidRoot' : Read-only file system".
I suspect Android system partition as read only but does know way to change.
I would appreciate your clever support.
Thank you in advance.

You could manually create the folder if you have root. By using those Root File explorer on Google Play Store.
I recommend you using this one: https://play.google.com/store/apps/details?id=com.clearvisions.explorer
Open the app then go to the root section, create a new folder name: AndroidRoot
And you are good to go.
If the above method didnt work, type these command one by one:
Code:
adb shell
su
mount -o rw,remount /system
You can mount your /system back to Read-Only using this command:
Code:
mount -o ro,remount /system

If so, you have done what I thought could not be done! I tip my hat to you, with your tenacity and your technical understanding of the complex issues involved.
If I had a Linux system myself, I'd be half-minded to dig out my old Nexus 7, deliberately bugger up the bootloader, and follow your instructions for the sheer technical challenge!
--------------------------------------
Some general thoughts...
The Nexus 7 is old (c.2012), and likely not many people use it anymore, but that's not what's important here. What is important is the persistence, the huge technical ability, and the sheer bloody minded refusal ~ by some ~ to let their Nexus 7 die... to go into what the poet Dylan Thomas called that 'good night'...
"Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light."
https://poets.org/poem/do-not-go-gentle-good-night
And in so doing, mayhap enderzip and others, have provided potential clues for other devices, other hardware, other phones or tablets, when faced with similar hard brick problems. One can but hope.
The above post by enderzip is technically way beyond me, and I have no immediate use for it, but it's a fundamental distillation of everything XDA stands for - namely, experimentation and creativity.
It's basically, amazing!
Thanks enderzip
Rgrds,
Ged.

Yes, I have successfully unbrick my Nexus 7 WITHOUT any type of blob file i have generated before.
And no, you should thank @Jirmd instead of me. If he didn't post his thread, my Nexus is still probably a paperweight.

Thank you Enderzip. I succeeded the creation of AndroidRoot with the command for write permission on system.
I have another issue about extraction of SBK of my bricked Nexus 7. I prepared everything (download of fusee-launcher, pyusb installation ...), checked connection of my device through APX (see below) but when I type sudo ./fusee-launcher.py –tty dump-sbk-via-usb.bin I got :
[email protected]:~/Downloads/fusee-launcher-n7$ lsusb

...
[email protected]:~/Downloads/fusee-launcher-n7$ sudo ./fusee-launcher.py --tty dump-sbk-via-usb.bin
sudo: ./fusee-launcher.py : command not found
Sorry to be blocked again.
@enderzip
I found a solution to my issue by allowing the "execution of the file as program" in the permissions of fusee-launcher.py file.
Fusee-launcher started but quickly stopped before application stack dumping : message delivered by fusee-launcher is to use USB 3.0 and I realized that I have only USB 2.0 on my old desk computer.
Does someone know how to patch EHCI driver ? Is it a possible solution ?
Thanks for your advice.

enderzip, wow, you soo good and cool. I am totaly glad for this, how you make your tutorial. And we must give thanks for AndroidRoot team and Jenkinsen. Without this people, we all have only paperweight.
Now, i will try make my moded mknvfblob worked standalone. Without Tegra 3, only on linux X86 PC.
And, i will try make tutorial for nexus 7 , how boot linux from usb, without multiboot. ( For case, when is your internal storage totaly unreparable damaged.)

Thank you Enderzip. I will follow your advice and buy a USB 3.0 PCI Express card and try later.
Again many thanks to you and Jmrd for your tutorial that will enable us to revive our bricked Nexus 7.

I know this might be a stupid question, but what is the boot.img at step 6? The grouper factory image contains a "bootloader-grouper-4.23.img" and a zip containing a "boot.img", I guess that's the file we should flash?

The boot.img is inside the .zip inside of the factory image. I think the name is "image-nz---.zip"
Step 5 works and returns the same as in the guide, the tablet shows the google logo, without the battery too low in the corner.
However, at step 6, i get this:
Code:
Nvflash v1.13.87205 started
[resume mode]
command failure: Error querying partition type (bad data)
bootloader status: partition table is required for this command (code: 8) message: nverror:0x5 (0x1000005) flags: 0
what should i do?
edit: for good measure this is the result from step 5:

@enderzip thank you so much for this detailed guide. Now I was able to generate the image (blobs) myself. When flashin the images (blobs), both the ones generated by you and the ones generated by me, following error is received... Could you help on this?

In this case, uss this command instead:
Code:
sudo ./nvflash --setbct --create --configfile <flash.cfg file name> --resume --download 8 boot.img --go
It may or may not work.

It doesn't work, it says that --resume must be first in the command. I moved it to the front, but then it said that it needed the bct file:
command:
Code:
nvflash --resume --setbct --create --configfile flash16.cfg --download 8 boot.img --go
result:
Code:
Nvflash v1.13.87205 started

I tried passing the testr.bct to it, but it looks even worse:
command:
Code:
nvflash --resume --setbct --create --configfile flash16.cfg --bct testr.bct --download 8 boot.img --go
result:

Hmm, have you tried switching the USB port? Maybe the USB cable too.

Sorry for my late reply, in this case, try skipping to the next step.
I must say that @enderzip guide make my nexus 7 back on it´s feet despite not having previously generated blobs. After some days of research and some nights via PM and FB messenger he managed to bring my Nexus back on. So Yes @GedBlake he managed to unbrick a nexus 7 with no previous generated blobs. But the mentor of this tutorial was @Jirmd. In adittion, thanks to this 2 wonderful persons that make my Nexus 7 back to it´s gold years!!!
