first the lecture
there is a 99.9% chance to destroy the player
lecture over
to review your points
1. newest firmare required -
there is none
2. newest firmware updating tool required
3. newest tool to restore/backup firmware required
there is none yet
4. tool to fixed dead players
there is none (ish)
basically you have a no-brand mp4 player using random firmware - you can not extract ths firmware for restore later.
there is no new update that will do anything to your player at all, so basically no ne features to be gained
if you had a branded player like onda, teclast etc then firmwares are actively updated to add new features - but not on no-branded ones.
the best you could do is to try firmwares suitable for 2.0" screens in the download section and maybe you will be lucky - but they wi=ont give anty new features - in fact some of them may remove the games section or the radio.
the best you can do if you have success with one of the firmwares is you may be able to change the look by skinning the players images.
so you need
1. firmware from here - but select ones for 2" screen only!!!
rockchip firmwares
2. consumer update - various versions some work, some not, just try and see.
try this one for starters
3. rklogoedit - for updating and skinning the images
rklogoedit
4. checksum fix tool for when you have used rklogoedit and saved the file
checksum tool
5. read articles by member knob - rockchip GURU - the best

this is all for now - any problems you have or things you need to know regarding any of the tools etc above have been posted, so search and ye shall find
in short, you may lose features but WILL NOT gain any
good chance to fry the player for good
skinning the player is about all you can do (which is fun), providing you find a working firmware
have fun
