ShaunMT's Modified ROM for Nextbook NX785QC8G (Support Thread)

[Micheal]

You need to download the stock rom and install it.

[mjatmjatmjat]

you could download the system update from the next book site and use that to flash back to stock.

Thank you. I tried that but it is proving to be problematic. I'll give it another shot.

I installed ShaunMT's custom ROM on one of these tablets I have and need to go back to stock ROM (get rid of freaktab splash screen, etc). How would I go about doing that? Thanks.
I appreciate any help you can provide.

If you installed my TWRP recovery, you'll need to reinstall the stock recovery first. (It's on the TWRP download page.)

Then download and install the official update from the Nextbook website. If it doesn't boot properly the first time after flashing the official update, you might have to reboot to recovery and flash it again.

Also, the stock recovery and official update don't seem to reformat the /data and /sdcard partitions correctly.

After flashing you might have to reboot to stock recovery, wipe data, then boot to Android, then go to settings and do a factory reset with the erase sdcard option checked.

Thanks for the tips. I've tried it about 10 times now and nothing is working. It appears that "the official" ROM from NEXTbook doesn't work. Any other ideas anyone on how to get this back to a Stock ROM?

Funny, I was doing the same thing and got the message no OS installed, what the hell? Now wont boot past battery animation.



Shaun I sent you a PM

I didn't get a PM from you...

It sounds like your system partition either failed to flash or flashed to the wrong location in NAND memory...

Are you still able to boot to recovery? If so, you need to try to flash again...

If not, you'll have to use the PC flashing tool...

Resent pm...

Sorry man... I know the stock recovery and stock update.img ROM format are a little flakey, but I've never had so much trouble installing them... I think I'm out of ideas...

I would first try whatever you were using previously... If you are using stock recovery and flashing an update.img format, the update includes a parameter file... which is one reason problems occur. You want to flash again with the same thing to insure the parameters are the same...

Newbie so please be patient but stuck on nextbook loading screen

I am unsure where I went wrong but the problem is the nextbook load and I see the freaktab emblem then converts to nextbook with animation going across the word, after 1 minute or so the animation stops and the nextbook is solid and just sits there (let sit for 15+ minutes).

I completed the following

1) verified my build was compatible
2) dowloaded installed TWRP to external SD through my computer and put in nextbook and booted, everything seemed to work fine
3) downloaded 4gb partition to external SD through my computer and put in nextbook and booted through TWRP (held power button with volume up)
4) downloaded OS again to external SD through my computer and flashed through TWRP
5) did factory restore 3 - 4 x without any luck

I went ahead and redownloaded the OS just in case to place on the microsd through the computer and currently attempting to reflash the OS in hopes of resolving my problem.

Nervous because this is a Christmas gift for my son and I was just hoping to get more space for his games and make the system more user friendly.

Any help is greatly appreciated for this newbie.

Thanks

Also just wanted to say thanks for everyone on this forum. I am sure I made a mistake somewhere because you guys all have done a great job delineating the instructions.

Just flash the twrp .zip version again and you should be fine. You might have to flash it twice or do an advanced wipe on the system partition and then flash again.

So here is crazy. I was entering twrp by hitting volume up and holding while holding power button.
So i tried the following. Held power button and both volume up and down at the same time which booted up and recommended me to delete something I believe (can't remember what) and all of a sudden I can boot up now everything is recognized and works normally and the internal and nano storage are much bigger . Sounds like I somehow fixed it so here is my question....how? Is holding both volume buttons "flashing" whereas just volume up got me to twrp? Just trying to understand because this stuff fascinates me.
Thanks for all the help

I am not sure why, but I think it was just the double reboot that solved the issue... maybe because the of the parameter size change...

Im guesing it asked you to delete an update.img file from your external sd so it wouldnt prompt to reinstall every reboot...

Check your internal sdcard to verify it mounted, if not, it will need to be wiped or reformatted in twrp for the new size.

So having 2 children this tablet is their gift for Christmas. As stated I was having the problem of the tablet loading and going through freaktab opening followed by the nextbook opening. The 1st tablet somehow resolved and now boots up. Feeling confident I whent through working on the second one

1) added TWRP without difficulty
2) added ROM zip through TWRP without any seeming difficulty
3) followed with parameter being added throuhg TWRP without any seeming difficulty

I have factory reset several times, rebooted several time, and now trying for a 3rd time to reinstall the ROM. Still continuing to get locked at the nextbook opening.

Any suggestions to get this thing working?

Thanks again
