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

[shaunmt]

Well, I've made a little progress this weekend, but still trying to track down and fix this bug...

Everything works but installing files... TWRP reports that the update script was processed successfully, but the log indicates that every step failed...

Still trying to figure out why...

Hmm that's a serious problem. Now even when its done what do you want us to test to make sure things run like what you expect on it to runrun

friends don't let friends buy nextbook

i am at my wits end with this stupid thing. i'll be honest it is a stylish little thing and all of the info on the box looked good but had i know nextbook stuck a ribbon on a pile of crap i would have walked away. who ever created the software is a bloody idiot. who in there right mind is going to put on the back of the box 8gb internal storage but only allow 1gb useable for installing apps. oooooooo but you can put apps in the nand storage. yea right 11 apps and only 2 allow me to transfer to the nand storage. i know what your thinking they want to sell devices and the next time you get one it will have more memory. yea that may be true but it will not be a nextbook. the worst part is that there is still 104mb of storage available but i can install anything on it. it just sits there taunting me and i always have to delete something to install something else. it's not like i have an excessive amount of apps on this thing. i still see the potential of the android but at this point i am missing the old ipad2

Keep watching the forums. I think I will have an easy way to change the sizes of the /data and /sdcard soon.

ShaunMT, have you been able to make any progress since last update? Looking forward to moving back to your rom from omas.

Yes!

Lots of progress recently!

I have, what I believe to be a fully working version of TWRP recovery, which has been in private beta testing for a week now... I believe it will be ready for a public release after another build and round of beta testing...

I've also figured out how to make the parameter patches to modify the /data and /sdcard sizes work... I'm currently trying to get these packaged up and sent out to my beta testers. They will probably be released publicly at the same time as TWRP recovery, along with a new customized version of the stock ROM that is flashable in TWRP.

When everything is done the process will look like this:

1. Start with a stock ROM, or my current customized ROM. (I can't currently help people revert from OMA's ROM, as I haven't used OMA's ROM and don't know what changes he made. I've heard it may be necessary to use one of the PC flashing tools to wipe or reflash the stock ROM paramters and partitions individually.)

2. Use stock recovery rkimage install to flash my TWRP recovery.

3. Optionally, Use my TWRP recovery to flash a parameter patch for your desired /data size. (/sdcard gets whatever space is left over. There will be a couple of options available. You can flash a new paramter patch anytime, but it requires reformatting both /data and /sdcard for the new sizes each time. Just choose a size and flash... the rest of the process is entirely automated.)

4. Optionally, install my pre-rooted, modified version of the stock ROM. (if not already using it)

FYI,

After this stuff gets released, I intend to spend some time supporting older devices before I proceed with building new ROMs for the NX785QC8G, but eventually I hope to have working versions of OmniRom, Cyanogenmod, and possibly more.

Will sure wait for it!

Thanks man!

You're the man!

The build we testers have is the test build. It works yes. So what will the final build be and is it possible to flash the final build with the rktools?

I'm planning to do a final rebuild with the latest changes from TeamWin.

I don't plan to release a version flashable via PC flash tools... If I release it, I'll be expected to support it, and I really don't want to... I figure anyone who knows how to take apart an rkimage or dump a partition won't need any help...

Oh darn lol. Its just many of us like to flash just the recovery. But it can't be helped I guess. So what partitions of storage will be available to us

Well... like I said, you can always take apart the rkimage, or backup/dump the recovery partition after installing...

I'm trying to remember which parts were required to make a working rkimage... the recovery partition and possibly the stock parameters and /or my modified boot image.

I was planning to start by offering parameter patches for stock (1 GB), 2GB, and 4GB /data partition sizes. The /sdcard partitions gets whatever is left over and everything else (system, cache, misc, metadata, kpanic, boot... stay the same).

Twrp is included in your ROM right

That's a good question....

Requesting comments:

If TWRP is required to install the ROM, should it also be included the ROM and reflashed?

Should I provide a standalone update.zip to reflash TWRP from TWRP?

Note: I cannot make an update.zip for stock recovery because I don't have Nextbook's private signature keys... the rkimage install from stock recovery works because the rkimage install doesn't look for signature keys...

I see

Hopefully no one would need them packaged that way, but you know us (you're users) we'll play around and need them eventually... Otherwise we wouldn't be waiting with baited breath for your recovery and ROM. Thank you so much for the hard work.
