TWRP Recovery with UBIFS Support For Amlogic Nextbook Tablets (Support Thread)

[shaunmt]

Okay i've just recently been given a "non working" nextbook next7p12-8g. It stops right after booting at the picture of the girl with headphones on. I did some digging made my way to this site got the twrp launched but it won't let me check "using external sd" in the installing or final manager and when i hit reboot it says no os. so I went and downloaded your stock rom kept it zipped and one unzipped (just in case). now the basic recovery option finds the rom but can't install it and since i can't check the "using external sd" i can't find it in the install window. just wondering if ya got any advice for me.

I'm sorry, I'm not sure why TWRP is giving you trouble, but I don't own that model to do any troubleshooting on.

It definitely sounds like you need to install a new ROM, but I don't know why you aren't able to find / open the .zip package to install it.

Perhaps another member around here who does have the same model can offer some advice...

yea i'm completely new to tablets and haven't given up yet lol i'm thinking of trying to use that adb thing to put the zip on the internal if i can get it to be recognized on the pc but since i won't boot installing is being a pain. i will figure this out lmfao the only thing keeping it from using the base install of the rom is the rom isn't signed.
other than that the rom appears to be working. maybe its something to do with the version or twrp i'm using? its the only one i could find on here tho 2.4.0 i think?

The stock recovery will only install packages signed with Nextbook's private signature keys. (Which we don't know.)

Are you using my TWRP version for you model from the download page linked in the first post of this thread?

yea i am. its probably just the hardware on it. sometimes i have to push the power a couple times to get it to come on and to do the volume - and power it sometimes takes a few dozen tries. It isn't my primary tablet, literally i fixed someones computer yesterday and they were like "do you want these 3 broken tablets?" xD they only found one and are planning on giving me 2 more same condition i figure if i can get the running i could have fun with them without endangering my pos Chinese tablet that i use ahahah.

I haven't used this recovery system yet so I don't know what options are available but see if there's an option to dump a log to the sd card, that should give you some more information about what's going on.

Hi guys. I am new here ( my first post) and before 2 days I got my next book tablet. to be honest with you I was between 2 tablets but I choose this one when I see that there is a support thread about next book tablets. The first day I manage to root it with Cydia impactor very easy I must say. The only reason I needed to root it is to get rid off the pre-installed apps and to get xposed framework and gravity box on this device and I be more that OK. But before I make something I need to be as more I can be "safe" and to be able to restore a backup and have my device functional again. I own a nexus smartphone so I am a little familiar with flashing and nandroid backups and custom roms and recoveries. So I get to the point I have some questions:
1.My board is EBM8000NBD and my model is NX008HD8G so witch recovery from the OP I must use?
2. The backup that I take with this recovery will give me the option to restore my device to a previous fully working state?
3.My serial number is YF071438021 and on the box say that manufactured on July 2014 in case you need that info.
I an happy to be here in that community.

Sorry for the double post but i look again in my build prop file in case i make a mistake for the board and model but i think that it doesn't match with no TWRP from the first post. Am i right? Here is my build prop. Maybe you guys see something that I don't see

NEXT7D12R ROM

Any news about the ROM for the NEXT7D12R?

Yep, still alive... I just returned from vacation with the family...

Your board is one I haven't seen before. I recently received a dump from one of these... will probably need to make a new recovery and ROM just for this version... not sure when I will get around to it...
