Amlogic Next8HD8G (NX008HD8G) Modified Recovery - Stock Rom & Flashable Root

[shaunmt]

I tried it with fat32 and fat. Still can't read any files, I've extracted the file directly to the sd card. I have not flashed any thing on the tablet before. I rooted it manually when I first got it.

So it boots to recovery, but you can't see any files on the external sd card while in recovery? Can you please provide a list with the full names of the files you've placed on the external sd card?

So, that's not what screwed up my initial attempt at root. I was using an 8GB card formatted FAT32.

Nope. Of course, your files could have been corrupted or your card could have had bad blocks or something... card could be going bad too... I've found cheap ones don't last long. I've had cheap Class 10 ones from places like Fry's that cost $10-$20 that didn't last a year in a phone. I try to stick to brands like Kingston or SanDisk now. My 32 GB is a Class 10 SanDisk. Got it from Amazon for $30-$35, I think.

Root successful. I'm good now. Thank for the help. It's amazing how fast the replies were this late at night

The card I used is a brand new, just out of the package 8GB Sandisk Ultra.

Maybe you should take a closer look at the script you use for root, just to be sure.

Yeah... I should be asleep... I've got a corporate meeting early in the morning...

Good to hear it. Are you still running the original firmware or did you have to reflash?

You need to put the zip file you want to install with the recovery on the card as well.

Here is the script:

show_progress(0.500000, 0);
ui_print("Installing Kyser Root");
ui_print("Mounting /system");
mount("ubifs", "UBI", "system", "/system");
ui_print("Installing su");
package_extract_dir("system", "/system");
ui_print("Setting Permissions");
set_perm_recursive(0, 0, 0755, 0644, "/system/app");
set_perm(0, 0, 6755, "/system/xbin/su");
ui_print("Creating Symlink");
symlink("/system/xbin/su", "/system/bin/su");
ui_print("Unmounting System");
unmount("/system");
show_progress(0.100000, 0);
ui_print("Finished, Reboot Now");

I will give that a try in the morning before work.

I would love to reflash. Any suggestions? When possible, I'd like to flash stock Nexus 7 ROM onto it.

No reason to reflash the stock ROM unless you NEED to in ordser to solve a problem.

The Nexus 7 would be a stock AOSP build, right? Haven't really given much thought to building AOSP, nothing stopping me though. Figured I do Cyanogenmod first, since I have to set it up in order to build CWM and TWRP anyway. Planned on doing Paranoid Android next.

We should be able to build anything based on Android versions 4.1 up to 4.3 without rebuilding the kernel, once I get the device tree setup. I've only got enough done to build recovery from source currently. I still need to pull out the proprietary files and set things up properly for a full system build.

Why do you change permissions for the /system/app directory?

Is the order in the symlink command correct? ("to" before "from")
[Edit: I just verified this is the correct order]

Where did you get the permission settings from?

CyanogenMod would be amazing

The /system/app permissions could probably be removed. It was for setting permissions for superuser or supersu, which I chose not to include, because I think the user should download the newest version of their preference from the play store.

I believe the symlink is correct. The su binary is installed to /system/xbin.

The symlink command and permissions were copied from a script for another Amlogic device. I don't remember which ROM or patch.
