Nexbook AMlogic root WORK!

[bryman777]

Well.... I still thinking finding a recovery that can boot from SDcard is the best way. It's the safe way!

However, I cannot even take a part and build my stock recovery! It wont boot. WTF

I have taken apart boot and can rebuild it no issues! But I cannot seem to simply take apart recovery and rebuild it using the scripts that are out there!

FYI, recovery has the keys to signing. If I can get somewhere with this, I think this is the solution. Alas I have spent most the day trying to make a working recovery even for my own Ramos MX tab to NO AVAIL

im wondering if you have to compile from linux, which would be very time consuming ..

[bryman777]

Finless i just found this, its called Linaro, linux for arm devices .. they have all the source code for building android arm devices . Imah download and install it, maybe i can get somewhere with the linux this time.

Sorry guys, I am taking a break from this ROM for now... My head hurts after spending all day yesterday learning and trying

I will be back though....

I know i probably dont know what im talking about here, after you build your recovery image, rebuild and resign it using the image builder ? kinda like recompiling it. if that makes any sense.

Bryman, if you've got a linux box this might be worth a try: http://www.erodov.com/forums/how-roo...325-page2.html. We don't have access to /data/local but perhaps sending it to the sdcard or external SD and modifying the commands to use that directory instead would work.

I was going to drop the Nextbook into the hands of a linux geek friend of mine to try out on one of his machines since I don't have any linux setups but haven't had time to meet up with him.

I downloaded mandriva earlier .. i just need to find the time to install it, hopefully theere will be a wireless driver for my pc .. I
found this on the amlogic wiki pages .maybe these cmnds will work using adb .. scroll down to the "Make recovery" ..
http://openlinux.amlogic.com/wiki/in...lding_the_Code ..
I could kick myself , last night i found a page for making a recovery.apk dump and rebuild, for amlogic devices. (look in your running services theres a recovery.apk running ).. coulda sworn i book marked it to look at later.. i even tried it using adb , but since i dont have root i couldnt access /data/ it said unkown access file/folder whatever . i was just typing for the wants of it. I will find that page again , and when I do it will be posted ..

Just realized these are .img files.

In my case, just trying to root this tablet to get full Google services / play store functionality since the factory ROM seems pretty close to stock already, although a CM port would be great. I bought this thing as a gift for my son since he loves playing on my nexus 7. Initially when at the store I glanced at this site and XDA to check if it had developer support or at least a root method but got caught by the manufacturer switching hardware / system on chip for this production run (a month prior based on serial numbers the same model number tablets were rk219 based but now they're amlogic). To date we've found no stock firmware, ROM, or recoveries and the manufacturer states that they are not willing to provide such.

we are trying to get root and build a custom rom , the nextbook8 has a meson 3 board, finless has a Ramos W13 Pro 8726mx/m6 dual core board.. once we get rooted and get a recovery rom/dump file we are good to go.
there is a rom on the nextbook site, its for a rk3066 board.. they dont have a am8726m3 update rom yet.. Im totally new at this stuff but ive been trying my best to come up with ideas.
so my question to you is, how to root this thing, and get a working recovery. its running ics 4.0.4 kernel 2.6.34.

In a nutshell
- Nextbook will not supply a stock ROM and the tablet is pretty locked down

- Any update.zip files we make will not work with the stock recovery system due to signing. We always get invalid signature. So a simple zip to apply su and superuser.apk we cant get to work.

- We cant root it using adb as there is no su etc and we cant get root to push any files.

- None of the rooting app out there work

- We cant seem fo make aor find a M3 recovery that will boot from sdcard!

Ideas?

Looking at their outragous prices, it amazes me that people buy from them.

Is the system UBIFS?

Try that in the e3 recovery. I'm guessing it has the recovery on the tablet...I hope....If not I would have to see if I can find an image you can boot from the sd card since Amlogic chips are programmed to default to that.

Bob, do you have a gtalk acct?

Yes it has a built in <e3> recovery. However that ubifs_root.zip fails to install as the built in recovery has been modfied by Nextbook and they changed the signing keys. I have made one just like this and we have used this and the recovery comes back with invalid signature
Nextbook looked it down by changeing the keys. They are not using default test keys

Now what we have been trying to do is boot a standard e3 recovery from SDcard. But everyone we have tried from other ROMs wont boot. I think because they are all made for MX not the M3 processor. Thus they get a blank screen when trying to boot a recovery from sdcard.

I also have been unsuccessful at making a recovery that boots. I have made a few ROMs for other AMlogic devices like my Ramos W13Pro MX. I have taken apart boot (uImage), etc with no issues. But for some reason if I take apart recovery and do nothing but put it back together (using the common linux scripts available out there), it wont boot. Cannot seem to figure out why? I am sure I am missing something simple but I would think the process is the same as boot.img?


Yes I have a gtalk account. I will PM you it.
