Here... Give this a try. Zipped up Rom Dump. Let me know success or fail.

I am downloading currently... I'm using a slow public wifi at the moment, so it may take awhile...

It looks good, but I haven't had time to package it.

Rom dump packaging

Whats the procedure for packaging a rom dump? Is that something a lightly experienced developer could try? Is there any command prompt that needs done. The most commanding I have done is doing th DD for the rom dump. Not much there. Are there any threds on packagin rom dumps?... Sorry for the all the questions. "Give a man a fish, feed him for a day. Teach a man to fish, feed him for life."

It's a little more involved. Search for how to create an update.zip to learn more.

I'll try to get to it tonight. I plan to release CWM along with with it!

Update

Been a while since I have heard from you last, just wanted to see if you have posted the roms at all. wasnt sure where you would post them.
Not to many good tutorials on creating update.zips from rom dumps.

Sorry man, just haven't gotten to it. I've spent all week testing new stock ROM builds and unbrick kits for the Next8HD8G. Trying to get a fix published for all the guys with completely dead tablets because they flashed an older stock ROM that wasn't compatible with an internal hardware change.

The good news is that what I'm learning will apply to other tablet models also. I'm now confident that I can fix ANY bricked Amlogic M3/M6/MX tablet (assuming a ROM is available). I hope to finish this up with the Next8HD8G this weekend, and then the Next7P12-8G WIFI issue and CWM for it are next on my list.

Nextbook Amlogic Tablets

Hello Again! ShaunMT

I have the following Nextbook Amlogic Tablets:

Nextbook Model: Next7P12-8G
Serial/Manufacture Date: YFG0713xxxxxx
Current ROM: Original Stock Rom
ROM build date (From build.prop):Tue June 18 14:31:16 CST 2013
Rooted?: Yes, with your method
Ever Flashed This Device Before?: No
Any Current Issues With Your Tablet/ROM?: None, except with battery
indicator sometimes always reads 100% so I used a battery calibration
app and followed instructions and seems to correct this. Also, short
battery life between charging.

Nextbook Model: NX008HD8G
Serial/Manufacture Date:YFG0713xxxxxx
Current ROM:Original Stock Rom
ROM build date (From build.prop): Mon Jul 1 17:41:00 CST 2013
Rooted?:Yes, with your method
Ever Flashed This Device Before?: No
Any Current Issues With Your Tablet/ROM?: None, except with battery
indicator sometimes always reads 100% so I used a battery calibration
app and followed instructions and seems to correct this. Also, short
battery life between charging.

I have the rom dumps for the both of these models.

I would be willing to test for you if I had a known
working stock rom to fall back to. However the stock roms
you have released seem to have problems for the newer build
dates such as the models that I have.

I have also read that you are working on revisions of the stock
rom with the newer build dates. I will wait until the revisions
are available and are stable. If they work well, I will sign up
as a tester for you.

I would package my rom dumps into a update.zip, but I am
not comfortable enough with the process and risk bricking these
tablets. I was waiting to see if Nextbook would release rom
updates, but have not.



Thanks again! For all of your great work!

Booting uboot from SD boot sector?

Sorry man, just haven't gotten to it. I've spent all week testing new stock ROM builds and unbrick kits for the Next8HD8G. Trying to get a fix published for all the guys with completely dead tablets because they flashed an older stock ROM that wasn't compatible with an internal hardware change.

ShaunMT - first and foremost, many many many thanks for collecting the stock boot.img. I now have my own conditional SD root boot. I haven't been able to get a recompressed kernel or re-integrated initramfs to boot successfully, like the testkeys uImage_recovery you supplied, but since my hexedited uncompressed boot.img loads, my plans to extend the NEXT7P's functionality are no longer foiled by an inability to boot a custom initramfs. At least now I can poke around the device.

Are you able to load uboot from the boot sector of the SD card on the M3/M6/MX tablets?

Yes you can. I've been testing disk images of bootable SD cards.

Is the stock rom NEXT7D12R already close to leaving?

Not yet. When I get started on this one, I'll contact you, as I will need someone to test and I think you may be the only person who has asked about this model so far.

Any luck yet?

For the sake of my sanity, please tell me you have 7P12-8G coming soon. My unit serial #YFG0613 is so clogged with crap I'll never use I have to remove apps I DO use to install others.

Claiming 8g storage and filling it with 7.5g of unusable, unremovable garbage is ridiculous.

Possible solution

Shaun has been understandably busy and in the meantime someone else posted another rom for the the 7p12-8g. It worked for mine, wifi is fixed I have root (using Shaun's root) and I have link2sd putting all my apps on the sd card. My only wish is that I could adjust the system partition size but I can wait for that. Here is the link.
