unbric kit

[professor_jonny]

Is there a way to create an unbrick kit from a dump from my own device ?

or am I able to use fastboot from the available unbrick kit's and reflash back an original boot image?

I'm just wanting a recovery method before I stuff up a boot loader flash.

First... it would help if you identified which tablet model you have.

Second, it is possible to create one from a dump, but it is not simple process. Look for Christian Troy's post with instructions over at Slatedroid.

If all else fails, I can create a rescue SD card image that can be flashed to an SD Card like I did for the Next8HD8G models.

My model is a nex712mc

i have just made some changes to my init.rc script and some initial ram disk mods and just want a recovery method just as a backup before I either hard or soft brick it.

This is my info from my build prop I provided a dumps on the forum here in the past of the two devices my kids have.

I don't recognize this model... do you have a custom recovery for it? You won't be able to successfully flash anything without a custom recovery. You'll want want a recovery that uses the correct kernel for your device also, because the NAND partition map is hard coded in the kernel.

Assuming, you have a compatible recovery, you should always be able to boot a custom recovery from the external SD card, as long as you don't flash a bad bootloader or bad graphic drivers. The only time an unbrick kit is needed is if you screw up the bootloader partition or the graphic drivers.

I have dumps but i'm un aware how to create a custom recovery or unbrick kit from them as of yet but I will have a read over at Slatedroid for this info.

You would not happen to have a crc of a kernel image from one of your recovery/unbrick kits to verify with mine?

What files are the drivers for the graphics so I can run a hash check on them also ?

update:

I believe this is the post you mention (here)

where do i get the uboot.bin file from to flash to the mbr and the stock rom ?

it just says get if from the stock rom, and there is not one floating around for my model apart from the dump i have and it is not really a rom but a dump of the flash partitions?.

I don't have anything for that model.

If you want to upload your rom dump for me, and I can add it to my list of TWRP recoveries to make this weekend.

I have two both the same one with a newer build date either would be suitable the boot image is the same for each so they should be interchangable I guess ?

you may have them already as i posted them ages ago in the other thread but you may of missed the closed links here they are:

https://www.dropbox.com/s/cqw3tgm8wj1g5ht/next712%20newer%20model.rar

how do I create my own custom recovery from the dumps I have im happy to try if pointed in the correct direction?

I must have missed them, or misplaced the downloads, because they aren't in my collection. I'm downloading them currently.

I build CWM or TWRP from source. I start with Christian Troy's Elf2 source code, which has already been modified to support UBIFS file systems on Amlogic devices. I modify the device source for whichever model I'm working on, then compile it. I then unpack the stock recovery to get the stock kernel and repack CWM / TWRP with the stock kernel.

If you want to do that yourself, you'll have to learn how to setup a unix dev environment for building Android from source and how to unpack / repack the boot / recovery images (it sounds like you already know how to do this part). There are plenty of guides available on the internet for setting up a unix environment to build Android, and you can learn more about working with the Amlogic boot / recovery images over at Slatedroid, but I don't have much free time available, so my time is better spent on development than teaching.

You ROM dumps look good. I'll use the newer one to create a TWRP recovery. I'm planning to release package and release recoveries for nearly a dozen devices this weekend. I'll move yours to the top of the list and send you a link to test it before I release it publicly.

Hi there is there a SD unbrick kit for the next7P12-8G serial YFG0613070968? It is hard bricked nothing I've tried word only turn a light on in the bottom when charging. thanks

Not yet, but new ROMs for the Next7P12-8G are up next for release. I'll make an unbrick kit for it at the same time.
