[angelobiz]

hi to all. i have a unknowed tv box con chipset Rockchip 3229 and 2mb ram and 8mb memory. it work very good... but i like to "play" whit firmware and so i want to be sure to restore its stock rom.
i have used RKdumper for make a backup... but i dont know how i can do whit this file....
i think i need loader for upgrade firmware... but.. where i can found it?
i put some picture of backup that i have ....

i read that i can found loader in file backup.img..... i have if from rkdumper, but i cannot extract it. i have tried to use imgRePackerRK v. 1.06 but is say "unknowed format"....

i try to use it, but i have same results- i have dump backup partiton, but cannot extract file in image
i can extract system.img.... but for be sure to have perfect backup, i need to know version of bootloader of my tv
and have it... this i dont know how i can do.
in build prop i have this:

# begin fota properties
ro.fota.platform=RK3229_6.0
ro.fota.type=box
ro.fota.app=5
ro.fota.id=mac
ro.fota.oem=sunvell3229_6.0
ro.fota.device=T95D
ro.fota.version=MV4.20170807
# end
now i try to looking for firmware .... but i not found this version, only more older....

this is android tv, it have 2mb ram, and 8gb memory. it work very good... so i want a good backup, before i start to "play" :-)

Hi ,

maybe you can find a working Stockrom for your Box here :

http://www.wechipbox.com/-ezp-24.html

for Backup (if you have Root) u can use TWRP ( if avalible

for your Box) , or use AT2.35 (AdvancedFunction) ,

and here some (maybe helpful) Links :

http://freaktab.com/forum/developmen...ndroidtool-2-3

http://freaktab.com/forum/developmen...ew-rk-2-1-tool

little bit old , but the Infos can be used for newer Tool , too , i think .

greetings / good luck / gefattern

thanks, but i have just do it....i have a bachup of rom, now i dont have bootloader... i miss only this... and i cannot have it whit AT2.35 because cannot dump bootaloader and i dont kno which booloader my box have..
it isnt a clone of T95d (as write in its buildprop) because my tv box have bluethoot too....
i need a metode of dump or knowwhich boot loader,
its firmware use

Hi ,

you can make a full backup with AT , with Bootloader , this can be used for restore .

Hi , what i mean is u can make a full backup of your Stockrom with the

Androidtool , no need to do it with rkdumper .

Is it right that you want a backup of the Stockrom , or what do you want ???

Again.... i have do backup whit Android Tool too... but it DON'T MAKE BACKUP OF BOOTLOADER :-) :-) or i not have understand how i can do it whit AT....:-)
do you know how i can make a backup of bootloader whit AT2.35 (i mean loader.... 1 row in AT2.35)
i need this file in picture
ps mmhhhhhh maybe i can do whit "export idb" ? IDB is loader?

If you have full Rom you have the bootloader. It unpack into first folder of the tool. But if you have the entire firmware your good to go. Play a way.. if you want to unpack the loader you need to do a Lot more reading in Rom dev section.

Best of luck and Thanks to Gaffattern for trying to get you what you need.

Hi ,

i am not sure if this what you want is possible , but if you split the full .img file with AT ,

the Loader comes out too , but you not need to backup the Stockrom splitted , u can make

a full backup of the Stockrom (to use for Restore) with AT (i think , because never done self) .
