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

[shaunmt]

Shaun I'm downloading your ROM now, gonna give it a try tonight. not sure if it was already posted somewhere and I just missed it, but how do you boot into stock recovery on these devices??

When you hold power and volume +, after logo with "No Command" appears, tap Volume + again... then the menu appears.

How do I go about looking at the build.prop file?

type "cat /system/buildprop" in a terminal app

or download a build.prop editor app from the market


Note: If you're not using the original stock ROM that came with your device, some build.prop entries may not be accurate...

For example, if you are using one of my ROMs, I've tweaked a few build.prop settings and the build date would be from the stock ROM I started with (usually the latest known stock ROM for the model).

Thanks for the update!

FYI

The first 4 digits of the serial number are the month and year of manufacture.

You can also check the exact date and time of your Android system build in the build.prop file.

I insalled the update easily enough. No issues other than battery reporting issues. However I'm currently using Omas 2.1 for the space. Bootstrapping PAs gapps to get playstore working. Hope for a cm ROM soon as I now have a small child and no time to work on it myself. Going to try to strip your update and install via the rktool to try and get the space while preserving compatability if Omas doesn't work the way I want.

Yesterday I purchased another of these limited edition tablets. I fully charged it and used it heavily to see what would happen with the battery. Lo and behold it ran down to the 14% warning and I plugged in and recharged. So it seems there isn't a battery issue with this one. This tablet was manufactured in June of this year as was my last one that had all the issues. I'm willing to bet that all the tablets having the battery issues were made in June. If you still have the box check the sticker on the side.

The only issue I have found so far with one is one that has been addressed in other areas of the forum and that is icons disappearing from home screen after every shut down and restart. Switching to another launcher seems to have resolved that issue.

yes they will help. as an experienced android user i can help as well. for now the basics will work due to cm or omnirom not built yet. but yes this device is great

Thanks for your help everyone

Thanks guys for taking the time to help a beginner. I look forward to ShaunMT's patch that will help with storage.

[mel4787]

Got you. Time to make a note on my apps and flash your ROM. Then use your patches. Honestly your ROM is better so I'll use your setup when things for your patches workwork

[shaunmt]

OK. So is it possible to use OMA ROM as a base as well or use your ROM for them

I don't know... I haven't used Oma's ROM or done any testing with it and I don't plan to...

I THINK it should work... but you'll have to test it and find out...

If I can get the update script working, this is what it does:

• Backup current /system, /metadata and /kpanic so they can later be restored in a new location
• Install a modified /parameter that does the following:
  • Increases /data size
  • Moves /system, /metadata, /kpanic and /sdcard to make room for the larger /data partition
  • Moves /sdcard to make room for the new /data partition and decreases it's size because it automatically gets whatever space is leftover
  
  
• Reboots recovery to load the new /parameter
• Wipes/Reformats the new /data and /sdcard partitions
• Restores /system, /metadata, and /kpanic to their new locations
• Reboots android

So, theoretically, it should work on any ROM that started with a compatible /paremeter, HOWEVER if the current ROM has a bigger /system, /metadata or /kpanic partition then the restore process may not work... in which case it would be necessary to reflash those partitions with a compatible ROM or partition dump...

Are any of your patches done? If so can I beta test that

I still haven't found any time to look at them again... I should really be working on my final paper for my college course right now, but thought I'd take a few minutes to check the forums...

When they are done, I WILL PM you some links for testing.

Thanks for your response. I installed superuser and an app that can remove apps I do not want and it worked. My remaining question is how to install apps directly to Nand Flash or External SD. Thanks for any help.

NAND Flash refers to the type of internal memory chip contained in this tablet. It's the same type of memory that is inside a USB Flash or Thumb Drive... On an android device that uses NAND Flash memory, the memory space is partitioned into virtual mounted drive partitions such as /boot, /system, /data, /recovery and /sdcard (a fake internal sd card) and possibly other partitions depending on the device...

The other users who responded to you are correct in that:

1. The current Android operating system versions only support Apps on the primary sdcard mounted at /sdcard. There are two reasons for this... first, Android was not designed to look for apps outside /system, /data or /sdcard and there is no standard way of naming the mount points for multiple sd cards... second, sdcards are often formatted fat32 so that they will appear when plugged in to ANY computer, but the most recent versions of Android enforce Unix file permissions which don't work on fat32 formatted sdcards.

Additionally, the developer(s) of each Android app decide where their app can be installed. Some install to /data/apps by default, some install part or all of the app in /sdcard, some allow you to move them after install and some don't... their decision is enforced by the Android system. This is why some apps can move and some cannot.

2. The others are also correct that I am currently working on some patches that will increase the size of the /data partition (where most apps usually go) by decreasing the size of the "internal" /sdcard. I hope these will be done soon, but testing has been troublesome and I've been extremely busy with real life recently.

I hope that answers your questions in greater detail. Keep reading the forums for future updates.
