Intrigued by DeadMan's posting of this device's "Twin", The Prestigio 3072B, I searched for similar RockChip Rk27XX based ebook readers.
I found the
firmware upgrade tool for the 5" Prestigio Libretto PER3052B and searched for other readers using the same "RK28DM_Setup.exe"
It looks like the
Delstar from Walgreens has the same firmware tool, but it is at version 1.22 whereas Prestigio's is at version 1.27. Anyway, I was able to connect to the Next1 using the RK28DM.exe.
Here's what firmware version (0.4.16) originally came with my Next1.
After noticing the Restore button, I searched for possible insights on how to backup my Next1 firmware BEFORE I do damage to it!
I came across
this thread for MP3 players, and after creating an empty text file called "rkusb.tag", I placed that empty file in the root of my Next1's flash memory using the supplied usb cable.
After that, I disconnected the usb cable, and shut down my Next1. After rebooting, I found TWO hidden partitions (one 150MB; the other 80MB) that were now VISIBLE on the Next1. I did this all on my WinXP SP3 computer.
I quickly backed up those two partitions onto my hard drive and began exploring my Next1's OS.
I haven't found anything I could easily mod, but did take a text listing of all files therein that is attached below. I also was able to locate a copy of the Next1 manual and attach same below.
Hey, this is fun!
Next (pardon the pun), see if similar .bin/codec files exist....
