I have one a similar model, only it's branded the Elonex 700EB. It's a decent e-reader and selling in the UK for 79lbs. I'll post a review in a few days.
That is a very heavy reader you got there! Don't think that would be very portable!

I've been tempted by something like this for a while. But have decided to wait for better versions of the cheap androids to come out... Or a decent battery life Win7 tablet... Or just a netbook... Crap it!

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. show attachment »

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....

Very nice. I was running the same software, and did browse through that same MP3 forum last night as well. But I certainly didn't think it would work with ours.

Excellent job jumping on that Will be having a look after work today as well.

nrapallo,

That is some impressive detective work! I am anxiously waiting for my Next1 to arrive.

I have high hopes that the 800x600 4:3 display will be a significant improvement over the typical 800x480 16:9 LCDs in the Augen, Slick, etc.
I'm also hoping that there's a way to use somebody's firmware to add support for video playback.
I don't use it often, but it sure is handy to have ebooks, music and video all on one device for long plane trips.

BTW - did anyone notice that the Prestigio PER3072B spec sheet says that it runs Linux?

Thanks, I always go "full-throttle" when I'm investigating things... Just my nature!

Attached are the specs showing that OS as being Linux, but I suspect it's an embedded version, as the file structure on those hidden partitions reveals no true OS.

I like the ebook capabilities/specs of the RK2729 given here:

It's really not all that much heavier than the Kindle.

OK well, I have extracted the Prestigio firmware, and started to compair files. Most are identical, but of course there are a few that are differant. The BMP0.BIN contains many more images, due to the extra features like video playback icons, file format icons, stuff like that. I have only tried swapping out a few of the files in SYSTEM folder, but it always overwrites them with the original file - and deletes anything extra I stick into sub folders. In the root it leaves extra files alone. Larger images in the Nextbook files are 800x600; The Prestigio contains 800x480 images (ie. start up images)

It contains a few games, and a a couple other utils.

I may just start simple and change the boot up image to see if it will let me get away with that for now before going to nuts.

I was going to swap out the entire contents with the Prestigio firmware into both SYSTEM directories on the device, but have chickened out for now. Called the store I bought it from and they have run out of stock... go figure right before xmas

I do suspect that it will just overwrite anything I copy into the main folders with what it has stored in memory.

Still trying to figure out how it checks for a firmware on the SD card. I will start rebuilding the firmware img file with files from both devices and see where I get. Might be the RKxxIMG.CHK files... Before it lets me change anything, I believe it will have to be a complete firmware change.

Will keep anyone interested posted as I play around. I may have to hit one of the folks up that bought the Slick for a copy of the system files from that device as well since it is 800x600 as well.

The Slick is 800x480, I picked one up but I will probably return it after the Next1 arrives. I doubt there is much you want from its firmware. Its firmware isn't very good imho.

That PER3052BW firmware is for different specs than the Next1, a closer match is the PER3072B which as of yet has no firmware available. I'm watching for it as I think it has more ebook formats as well as video playback support! It looks like such a sleek product; I would buy one if I could, but they don't sell it in North America.

BTW, I saw something in the Russian the-ebook.org that said another "Twin", the Citybook s701, is slated for Spring 2011 shipping! Where are these similar devices being sold...

I think you would use the RK28DM_Setup.exe to install the firmware upgrade tool and load the desired *.img firmware and update the Next1's firmware. I don't think the .img is upgraded using the microSD card at all.

I haven't found any (compatible) firmware .img's and am really holding out for the Prestigio PER3072B's! I did manage to locate a similar firmware (firmware_Hyundai_HYV_C-700_v-1.0.5.zip) in a French forum for the JWD PMP-7100 liseuse. I've compared this firmware with the Next1's 150MB "hidden" partition and there are few changed files, as follows:
Code
Comparing subdirectories:
- E:\Nextbook_Next1\firmware_Hyundai_HYV_C-700_v-1.0.5\extracted firmware img
- E:\Nextbook_Next1\Nextbook_Next1_hidden_partition\150MB
Differences: next1_mannual.pdf only in E:\Nextbook_Next1\Nextbook_Next1_hidden_partition\150MB rock2729boot.bin different(both have identical times) version.bin different(both have identical times) lang\japanese\cmap\h only in E:\Nextbook_Next1\firmware_Hyundai_HYV_C-700_v-1.0.5\extracted firmware img resource\bid\bmp0.bin different(both have identical times) resource\sid\stringid.bin different(both have identical times) system\base.rkw different(both have identical times) system\save.bin different(both have identical times) system\codecs\rk28_jbig2.rkl	different(both have identical times) system00\base.rkw different(both have identical times) system00\save.bin different(both have identical times) system00\codecs\rk28_jbig2.rkl	different(both have identical times)
-- 12 files listed

I've used that firmware .img as a base for reconstructing an .img for the original firmware 0.4.16 for my Next1, though I haven't tested it yet if it actually can be re-written to the Next1's on-board firmware. [EDIT: 29-Dec-2010 IT DOES WORK!] I've loaded it in the RK28DM.exe firmware tool and it recognizes it. I'm not going to try using it though, until I can get that Prestigio PER3072B firmware to work. I can then post it to mediafire.com as and when required.

The Slick firmware may be a better match for the PER3052BW you were investigating, but it wouldn't match the specs of the Next1 (or PER3072B).

I think the key files to expect improvements would be:
BMP0.bin
Rock2729Boot.bin
stringid.bin
base.rkw
ebook.bin
pytable.bin
Right now my best utility of this little reader is Google scanned .pdf ebooks and any related .epub version (that I previously used with my iLiad, however, the iLiad is e-ink and is not backlit, which I truly desire!)

Another GREAT use is a comic book (.cbr or .cbz) viewer. I first have to unzip the files to their own directory and extract those individual .jpg's, but it's worth it, seeing it rendered in colour and hires (800x600 is better that my 640x480 REB1200!)

DeadMan, have you found any niche use for this product?
