Amlogic Next7P12-8G Modified Recovery - Stock Rom & Flashable Root

[Eugene_V]

Thanks for your super fast response

Yeah, I know that function has been built in for a bit, but the deal is...these tablets don't seem to realize that. When I install an app it gives me the option to move to the SD card, but that doesn't work. I tried it on all three of my kids' next7P12-8Gs. Doesn't work. So, after getting fed up, I decided to go for the root, hoping to bypass whatever crap bug in nextbook's software which was preventing me from utilizing this feature (perhaps due to an "incompatable" SD card?)...

I have exactly the same problem (google play and apps don't move to sd) with my Next7P12-GP (same model as yours but 4GB). Must be some code error (ROM).

I noticed last night that there is an option in the android source code to enable / disable the feature.

It looks like it require a custom ROM built from source to fix it.

P.S. I've got Cyanogenmod booting on Nextbook... I just need to work out some bugs...

Great abt Cyanogenmod. You are a Master!

What about the file system. May we move to ext4 under aml core? I heard that actually this is the best file sys for Android.

By the way I ran Titanium to move apps to SD. Message says all done, but in fact all same - so Titanium gets false info about movings apps. I tried with 10-12 different apps, but same.
I took a look at the file build.prop but there are just a few options. So there must be somewhere a config file with many more I think.

If I can be of any help pls don't hesitate.

u can try link the apps by link2sd

i think it s the best thing u can try

I think I've got most of the bugs worked out in Cyanogenmod. I've got a new build that finished compiling last night that I need to test today.

The file system is hard coded in the kernel. Changing the file system or partition layout is going to require a custom bootloader and a custom kernel.

That could possibly work.

I have tried them all (quite all at the Market) but unfortunately no one does the job. Will try this evening with the Android SDK, ADB and run:

"adb shell pm getInstallLocation (Android <4.0)
adb shell pm get-install-location (Android 4.x)
This results in a numerical value to state where the default install location is (0: phone, 2: external).adb shell pm setInstallLocation 2 (Android <4.0)
adb shell pm set-install-location 2 (Android 4.x)
This sets the default install location to the external storage"

But before any intervention in the system must do a full sys backup, and actually only "chaunmt" may help with the eagerly expected "clockworkorange" recovery mod!
Just kiddng, remember a old enlish movie.

CWM seems to be working perfectly, including the nandroid backup and restore functions. I think the version I compiled even includes a mod that is supposed to map bad nand blocks during formatting so that they get skipped.

I may start posting CWM as early as tonight... but I'm going to have to make versions for each tablet model. I thought I could do a generic amlogic one, but I'm afraid bootloader, kernel and partition size variations between models may lead to problems.

I'm also so extremely close to finishing CM10 that I'd like to get everything working on it, in case I need to change any of the recovery code to make it work correctly.

great news and great job

i hope cwm have it s way to next800t too

It will. The same recovery will work on all Amlogic tablets, it just needs to be packaged correctly with the proper kernel and drivers, which I already have for the Next800T.

That could possibly work.

For Samsung devices it is possibile to unmount the internal SD, change the partition size, link the external SD like internal memory.

Yes, this should be feasible on all devices. I haven't tested it, but it should be possible to swap mount points in the boot image and recovery image. This would of course require custom boot and recovery images.

I've wondered if the data partition could be swapped with the larger internal sd card partition. Not sure if this would work due to the file systems.

I'm fairly certain the internal and external SD mounts could be swapped, but this would create potential issues with booting from external SD card.

We could also probably just not mount the internal SD card at all, and instead mount the external SD card as both internal and external. Sacrificing the internal SD space would probably be worth it to those of us with huge SD cards.
