Best way to backup Jelly Bean 4.2.2 firmware, from a Rockchip M1002B device(Empire Electronix) Tablet.

[scorp76]

Hello!
I was looking for a rom for my empire electronix 10.1" tablet, with an Rockchip Rk3168 inside.
Also to root it and to unlock the bootloader, but after really reading and reading...More as an month, i got stuck.
Rooting was only possible with rootking, supersu didn't work.
Bootloader, cant find any info how to do this with my tablet.And trying to give commands in terminal gave me no access.
Rom, well il guess after searching the web even with my firmcode, it leaves me without any option..
But, with trying and reading how to make the 4.2.2 os work quicker i got some progress.There are still some tweaks but i don't wane go further on without..A backup.

I flash some android boxes and tweak it, but i thought its nice to make this older hardware working faster and i learn something besides it.
But i hope someone can help me a little bit, as we say in my country..Due to the many trees, i cant see the forrest anymore..
What i hope is possible is to first make a backup off my stock rom, android Jelly Bean 4.2.2.
What i understand correct me if i am wrong, is that most apps like Twrp an cmr and so on, are based on a fitting recovery of the stock rom..And if that's correct i cant use them, but are there maybe another tools or solution to do this.
I read about them, but for example mtk, is only for that brand not for my empire tablet.Or not..

So my question is, what is the best way or tool to backup my RockChip firmware(Bootloader, etc) so that i can flash it back when needed.Without changing anything in the existing ,recovery and so on?
Here some specs, and a thank you for your info!!

Hi There,

Have you looked at this http://freaktab.com/forum/developmen...ew-rk-2-1-tool

blinkone, thanks for your response!
You know, i got confused by the many ways there where to backup.Also they go deep into it, no problem but i didnt got my answer , so stays confusing for me.I read and some say its to backup, others say not complete....Uhhh, i just wane make a backup of the stockrom before i do anything with it...So backup and then i must put it in the slicer to make a img file, what i can flash back onto my tab.
After reading 20 pages, i open the case off the tablet because i lost my Board ID.......

Yesterday i googled again the board id, another question rise ....I found a tablet with the name, Touchmate mid101, wich has the same board ID as mine (YK108-RK3188-V1)
Uhm, is a board ID always the same, even if my tablet is a empire electronix, the base or board is the same only the outside is made by the manufacture itself??
That would be good, then i have at least a stockrom.Only thing i have to figure out is, do they use the same chip, and wifi chip, i think so if the board is the same.
Got only a few things what are maybe not configured or its not the same, my experience is not that deep yet..
On another forum someone asked for the firmware of the same board id, the direct him to this tablet: http://www.touchmate.net/Product/rvd...atid/tablets-4
This is only a 16gb tablet with a faster cpu, the 8Gb version matches my hardware, with the 1.2Ghz Cortex processor(RK3168 @ 1.2GHZ)
Also the 16Gb has Jelly Bean 4.2.2, and the 8Gb had Jelly Bean 4.2.1, so mine is newer.I have to figure out if their is a new firmware for that one...RK3188 kernel, or do i see that wrong..
Thanks!
