Nexbook AMlogic root WORK!

[bryman777]

the reason those other uimage, and uboot.bin files were not working was they were for kernel 3.0 .. we need the uimage and uboot.bin files for kernel 2.6.34 ..

[Finless]

I got all that....

I have all the files needed from the dump EXCEPT u-boot.bin That is not in a partition. My understanding looking at my MX ROM is that u-boot.bin is also in the first part of bootloader.img

So in order to get this done we need u-boot.bin. I am hoping I can extract it like the guy did from the post you referenced :

i just found this , from this site http://androidforums.com/google-tv/5...rmware-25.html and this post .. #1236 ..

The other files like factory_update_param.aml are just simple scripts! So no worries there.

Now one problem of making the system is again the signing. I am studying now that bootloader is where this signing is not recovery. So we may have to find a bootloader.img for M3. I just am not an expert here but I think what we have is a "locked" bootloader like Samsung, etc has done.

But I will have all the other img files up for you soon.

Could we use a generic bootloader for the mx3 or a generic u-boot.bin ? cause i can see if i can find one, ill keep searching..

And thank you again!!!

[Finless]

I got it.... no worries. bootloader.img is the same exact file as u-boot.bin

Binary compare of my MX ROM shows they are the same so no worries I think.

However, finding a M3 bootloader that is generic may work just fine.

Now to work on system.

not sure if you have this or not .. itsa sign tool , found here post 1271 .. http://androidforums.com/google-tv/5...rmware-26.html ..

OK guys here are all of the cleaned up and good files from the dump so far!

All I need to do now is exctract system and make that. However ICS system is so generic these days you might be able to use one from another ROM for trying to unbrick in the mean time. The super important files are in this zip.

Just got my cable a fewhours ago and boy am I happy.
We have 2 Nextbooks with the AML chip, the Premium 8SE and 7P12-8G with Googleplay.

Tried the cable on both tablets and found out you can attach the following , Keyboard, Mouse and flash drive and they all work. I can access the flash drive from Astro and see all the files on it so I guess I could run or xfer them. Will look into that later..
So If Nextbook says the tablets don't accept add ons then they don't know their own prouducts.
I'm new to this android thing so I'm just learning ....

What kind of mouse and keyboard did you try?

I just tried a Kensington Bluetooth dongle that I usually leave connected to my laptop and it did nothing on this tablet - no annunciator, nothing in settings - the LED on the dongle doesn't even light up.

I had already verified that a USB flash drive showed up mounted in settings, but I didn't try to access it. How does it show up in ASTRO? I can't find it.

This tablet remains undocumented on their website. My guess is that most of their tech support people don't even know there is a different model out there, let alone that it supports OTG. Either that or they are being deliberately deceptive about it.

EDIT: I just tried the mouse I use with my laptop and it worked. It is hard to use because the cursor is dark and gets lost in my background image, but it works!

that was for an elf2 ..

Im replacing the files on the sd card ..
i need the u-boot.bin .. its the filesystem ..

i just found this , from this site http://androidforums.com/google-tv/5...rmware-25.html and this post .. #1236 ..

you can extract uboot from installed firmware first by reading ubootwhole
partition and then extracting bootloader part with some hex
editor.

Example of extracting bootloader:
in your cat /proc/mtd you
can see that ubootwhole is on mtd8, so
install Terminal on your box, type su
(you said you rooted your device) and give su permission to Terminal
app.

now:

dd if=/dev/mtd/mtd8 of=/sdcard/uboot.bin

this
will copy content of your SPI chip to uboot.bin on your sdcard. Upload it
somewhere and I'll see what I can do about extracting bootloader from
it.

About media partition, my fw doesn't use media partition so it will
be erased and overwritten with new partitioning my fw uses (it's possible you'll
have to install fw twice).
--------------------------------------------------------------------------------------------------------------


u think you could try to see if you can get the uboot.bin file ? this is just an example, Im not sure where the ubootwhole partition would be mounted.. but if you run that command it might tell you ..

FYI, I did try this a couple of times before reading Bob's message this morning. Two things: mtd8 shows up as NFTL_Part, not uboot.bin.

Also, I tried "cat /dev/mtd/mtd8 > /mnt/sdcard/NFTL_Part" and it did not stop dumping like the others did. I let it go as long as 8 minutes and it created a 1GB file in the sdcard directory! Apparently, it just runs off the end of memory and probably wraps around again!

Luckily, you don't need it - Bob said what you are looking for is the same as bootloader.

eegorr,


Keyboard was a cheap one from Newegg ( http://www.newegg.com/Product/Produc...Content-_-text-_- ) and mouse was just a small usb laptop one from Biglots that I bought years ago.

Sorry about flash drive , it was FileBrowser not Astro that I used to view. Can't find it on Astro but I'm probably doing something wrong.
Drive shows up as UDisk and I can access it . I just loaded some songs on it and they play and copy to tablet. I just discovered that the music player went out and was playing the music off the flash drive.

So, can you create a rooted version of the stock ROM for those who just want a rooted stock tablet, or will they have to go through the process I did?

Can you upgrade the ROM to JB while giving us access to Google Play and maybe some other cool features like extra app space? Can you update to the latest busybox and Flash versions?

Also, your Windows based flash tool will not work with our tablet because it is AMLogic based, right? So our only choice is to update via SD card.

I know we are taking this one step at a time and I fully concur - just wondering what your capabilities are.

One more thing - if I want to get rid of crapware can I just delete the apk file from the /system/app directory and reboot? I am thinking of Fring and Flixter in particular, but there are others.

I will try... Key is getting rid of the locked down loader.

Probably not! Requires a JB kernel! We are not even CLOSE to seeing if we can make a kernel! WAY to wishful thinking here.

Also, your Windows based flash tool will not work with our tablet because it is AMLogic based, right? So our only choice is to update via SD card.

For a totally stock tablet it will probably HAVE to be SDcard "unbrick" method which will probably HAVE to be used to flash a rooted ROM. We cannot update the stock ROM any other way due to the locked bootloader.

I know we are taking this one step at a time and I fully concur - just wondering what your capabilities are.

I am learning this AMlogic stuff everytime I work on this. So honestly... not sure what my capabilities are longer term.

One more thing - if I want to get rid of crapware can I just delete the apk file from the /system/app directory and reboot? I am thinking of Fring and Flixter in particular, but there are others.

Yes that is what you do... Best after removing the /system/app/junk APK to then do a factory reset so the dalvick cache has no junk left behind.

You going way to fast with this. We have not even got a stock ROM yet!

Ahhhh! That's better. It shows up in FileBrowser and even in the Yamaha AV Controller app - I am currently streaming music from the flash drive to my receiver - Bohemian Rhapsody!

heres where im at ..
something is definatly happening.. i put the boot.img and bootloader files in the generic android zip , resigned it .. the uimage, uimage_recovery, u-boot.bin on the sdcard ..
.. when the sdcard is inserted, it will not get recognized in the device manager.. okay pop out sd card.. hit the reset .. power off by looking in the device to make sure its off.. unplug usb .. insert sdcard back into device .. hold volume down and power button down for a long time .. the black screen gets some light, goes black ,, repeats a few times .. then nothing .. atleast its some progress .. im going to try a few more things .. if i keep at it hopefully i will figure it out..

[bryman777]

I think im just to bricked,, .. ill try when more files are done ..

Your awesome Bob .. ty ty ty ..

[bryman777]

bob would you know if a otg usb would work the same as a db9 serial to usb and serial card?

on a seperate note, have you seen the new china quad core tabs? the A31`s wth 2 gigs of ddr3 ram.. or a exynos 4412 with 2 gig`s of ddr3 ram .. if this thing dont work anymore, im going to spend a little money and get me a quality tablet ..
