Ok, I rooted my NT using external SD card and was able to toggle between android 2.3.4 and B&N OS. I have been spending days trying to figure out how to upgrade to CM 10.2 (and have been unsuccessful due to endless tutorials posting invalid files). I finally found a tutorial on this forum and there was a part that specifically said to not mess with the drive that my nook was plugged into. Well...too many windows up, too long on forums etc...long story short...I messed with that drive.
So now my NT boots up to the B&N start up screen; but I get a forced restart error and an error message that says that nook root file stopped working. The touch screen doesn't work and I can't do anything but power off.
Is there ANYONE who can help me? I'll be eternally grateful!
You might consider trying this repart.img method described at http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/.
files won't extract
When I googled feverishly for a solution, I did find that website and tried that method. The problem that I'm having with this entire process is that most of these files are invalid, missing a part or corrupted. I've tried using WinRAR and 7-zip and neither program is able to successfully extract the files; this repart img included. This project of mine has turned into a frustrating debacle!
Thank you for your reply, though!
I'd suggest you burn a pre-made SD CM10.x image from http://iamafanof.wordpress.com/2013...id-4-3-for-nook-tablet-imgsdc-boot-09aug2013/ and see if you can successfully boot and run it.
If that works you can proceed to restore the internal emmc image either by using the repart.img method or by flashing flash_stock_1.4.2.zip from https://github.com/succulent/acclaim_recovery_sdcard. See also http://forum.xda-developers.com/showthread.php?t=2575489 for potential helpful info and pointers.
When I extract files, this is the message I get from most of the files I unzip. I tried the cm10.2 img file and I couldn't extract it. I included a screenshot of the error message I keep getting. I've tried several different unzip programs and it's always the same error.
Bad download? Redownloaded and same error?

Did you try the alternate mirror on Mediafire http://www.mediafire.com/download/bo2qu6v4qo9p6a2/cm_acclaim_10.2.0-RC0_13OCT2013_HD_SDC_IMG.7z?
Also FWIW I use 7-zip archive manager program (www.7-zip.org/download.html‎).

I have Vista Home Premium 64bit and I did download WinRAR 64 bit edition. Whenever I try to install that there claims to be a corrupt file and I have downloaded it a few times from a few sites.
So I go back to the 32 bit version of WinRAR and that installs fine, but reminds me for better performance to use the 64 bit version.
Now, whenever I extract a ZIP or RAR file the Update.exe is missing or I receive a message about the CRC security not matching. AND if and only if I can get the files extracted when I try to install the ROM the Gtab is constantly stating a "status 7" error. I have tried TNT, VEGAn and 1 other ROM and each will not install.
Is there anyone who would be willing to use Skype or some other means to assist me in getting the tablet back up and running something, even if that's the stock ROM?
I do have Clockwork Mod installed already, that was the only thing that seems to have installed correctly.
Thank you in advance,
Brian
If I undertsand correctly: Youre trying to extract the contents of the "update.zip" file that comes as part of the ROM download?
If so.. you dont extract it, you leave it as "update.zip" in your sdcard directory.
I remember seeing a "pictoral" view of what your filesystem should look like in this xda somewhere. Ill try to find it.
No, I am having problem extracting the ROMs from Zip or Rar, so I went and downloaded Memtest86 just to see if there was a RAM problem. That checked out fine after an hour of testing.
Most every Zip or Rar I try to extract have CRC errors, even if it's unrelated to this site. But part of that causes the Update.zip not to extract at all and I only get the "recovery" folder and Command and the Update.zip had an error and doesn't extract.
I then tried it on a laptop with Win7 and I could extract some files then more errors, then I tried a Win XP laptop and that seemed to extract the files fine.
My latest is now the Gtab is bricked, stuck trying to install recovery that never ends. So I looked up for the USB driver and nvflash and the ROM that goes with that and the Gtab doesn't show up as a removable drive so I can transfer the files on there. I have copied them to SDcard but I can't get that to read the data.
So, at this point the Gtab is looping and I cannot get back into Clockwork or get it to show as a drive using the USB drivers and the -Vol and Power button.
Currently when I just power on the tablet in red text I get:
Magic value mismatch:
:"
Critical failure: Unable to start kernel.
Unrecoverable bootloader error (0x00000002).
FIXED
PROBLEM FIXED.
I saw another thread stating similar problem, located here http://forum.xda-developers.com/showthread.php?t=1026757 and followed the advice of a few people and now the Gtab is working again. Its stock ROM but the main thing is it's working again.
I am trying to get my viewsonic g tab back to factory. I installed the APX driver ok, and downloaded the applicable files. I try to run the nvflash_gtablet.bat script and it comes up with a file configuration error that the file can't be found. I am running windows 7. Any suggestions?
i have never done nvflash and never got brick and loaded multiple roms and went on dif dev branches
this is for 1.1
http://tapntap.http.internapcdn.net/tapntap/viewsonic/update-smb_a1002-3588-user.zip
and this is for 1.2
http://tapntap.http.internapcdn.net/tapntap/viewsonic/update-smb_a1002-4349-user.zip
rename the zip file to "update.zip"
hopefully you partioned your tab before nvflashing it. if not then please ignore this.
put update.zip in root of your sd card.
create a folder named "recovery" and place an empty file named command with this text inside
Code:
--update_package=SDCARD:/update.zip
then go into recovery and let it update.
hope i helped somewhat
ps to make files in win 7. i open notepad and paste code then save a command.tmp then i go and delete tmp. it leaves it as a file. and works

h i because you didn't have the image files to flash into. This is probably the most common mistake that beginners make.
Go to my website linked in my signature and go to the start here page. You're probably a code yellow.
A few months ago, I made a help thread on how to get my phone rooted after some roadblock. However, I didn't get any type of help whatsoever. So I decided to remain on the phone's base firmware for eternity. However, I decided to try again. Anyways, below is the opening post I made for that thread. I only included the parts I still have trouble on.
(i made sure to do a backup)
Let me sum up what I have done:
I've managed to follow a guide on a wiki(I lost the link however, since I ATTEMPTED to give up on this) that involved me downgrading my firmware, then do some steps to install cyanogen 1.4. Afterwards, I got to step that required me to rename some file to update.zip. I followed that step and noticed my computer didn't convert the file to a zip file(it remained as a img file) but continued anyway while finding that odd.
Afterwards, cyanogen tells me that it cannot find the zip file. I've search most of google and a bit of this site, and i've seen various solutions that failed me such as:
-renaming the update.zip to update
-using android sdk(which i have no clue on how to use)
So if you managed to read my long and boring story, let me ask one question:
How do I get my phone back to normal if rooting is impossible at this point?

the file staying an image file though you renamed it usually comes from windows hiding known file types' extensions. you can turn that off in your file browser through Tools -> Folder Options and somewhere over there there should be a checkbox that says "hide known extensions" or something.
(that means that if the file was originally called abc.img it is now abc.zip.img only the .img part is hidden).
the link you had to a wiki is probably this one:
http://wiki.cyanogenmod.com/wiki/TMobile_myTouch_3G:_Rooting
or any other one from this page:
http://wiki.cyanogenmod.com/wiki/HTC_Magic
good luck
Thanks to that, i've gotten a little farther. Hoewever, i'm stuck at flashing a recovery. it now says: FAILED (remote: not allow)
What is this?
EDIT: After hours of searching, it seems that this: http://forum.xda-developers.com/showthread.php?t=548218 is the answer. However, since my SD cards cannot be gold carded(since I need a gold card for this solution), i'm pretty much screwed until I find a compatible SD card. Thanks for trying though.
Hi guys!
I was hoping one of you could help me.
Yesterday i modified a build.prop file on my NextBook EBM8000ND (Next800T) tablet, causing it to get stuck in a bootloop every time it's turned on. I've been searching the Internet all day long but it's hard to find support when you have a device which no one in the world uses . It was rooted but I did a factory reset hoping that it would fix it. It didn't and now it's also unrooted. I tried to make a custom update.zip with the backup of the original build.prop file but the stock recovery simply refuses to load any update file. It always stops at verification. I used 7zip with store option. I tried signing the zip, I even edited the updater script to only print some text on the screen but the recovery still wouldn't load it. I tried to find a way to install CWM using sdcard but with no luck. When i tried to use ADB in recovery the device says: "failed to open driver control: No such file or directory". It might be worth mentioning that I found my device's ROM online with boot.img and recovery.img files and a .tar file which contains the original system folder.
Is there any way to make the stock recovery (since installing CWM or TWRP seems impossible) read my update file? Or is there another way to fix this? I only need to replace that single file.
Hoping to get help soon.
Cheers!
Been trying for days to extract the kernel from Nougat to use it within Marshmallow in order to downgrade with vibration working on nougats bootloader - but for the life of me i can NOT get windows to actually read these files properly. have all kinds of mounting programs, a java based converter that doesnt actually work (sgs2ext4) i end up with this loop of the same lines, and a 0kb converted file. I can mount the regular img file fine, but it will NOT open without some sort of error. the files themselves are just fine as they will properly flash and run when using odin (when compressed into tar.md5)
Tried wthin twrp hoping the file manager might just let me browse through it since the phone is already linux based and can actually see the information... but no dice there either. It doesnt go into further detail than just showing me that theres an img file present, with options to delete, chmod, etc.
what can i do to dig down to this zimage portion of boot.img that everyone insists the kernel is within? (i say insist cuz i havent actually seen it for myself!)
none of the tutorials ive come across address these specific opening errors - other than that the error is happening because windows cant read it
diskinternals wont work, osfmount will mount but i cant read it .... where on earth are these drivers or programs or whatever i need to actually allow me to browse and explore these files properly? and dare i say, recompress them once ive found what im looking for!
i did also try flashify, thinking run nougat, backup kernel, install marshmallow, restore nougat kernel, but it just leads to freezing on boot logo. I need to get within these img files to actually do what i want to successfully, switching out only that one specific zimage part of the file, leaving the rest intact.
very frustrated here, would very much love some help with this...
Try this, helped so much!
