It looks like it worked!!!!!!!!!!!!!!!!
[Android Software/Hacking General [Developers Only]] fun_:
congrat. please make backup of unmodified update.img and keep it safe place.

then you need to learn how to use AFPtool.exe to unpack/repack update.img, and RKAndroidBatchUpgrade.exe to flash it.

but before flashing it, please confirm dumped update.img is really for your tablet. there is small possibilities that lazy chinese factory person flashed wrong image ;)

you'll get system.img after unpack update.img. system.img is encrypted so you need to decrypt it by "rkDecrypt.exe system.img" on Windows command prompt. (please google where to get rkDecrypt)

then you can edit system.img with any cramfs tools. (probably newtuxboxflashtools is easy to use)

please check/compare build.prop in system.img and /system/build.prop on your tablet. it should be same.

Any chance you could give me the process of merging the system.img into someone else's custom ROM for the Archos 70 eReader?

Like this one: http://www.arctablet.com/blog/archo...tom-firmware-market-and-root-kasty21/?lang=fr
[Android Software/Hacking General [Developers Only]] fun_:
fastest way is just make update.img with their boot.img and system.img(do not use other files in rom for other tablets). in general it should work but you may get wrong accelerometer orientation.

another way is repeat someone else's changes on your boot/system.img. I don't know what is changed in that custom rom, so I can't tell you about detail.

tools and procedure are described in archosfans' wiki. if you are using Windows, newtuxboxflashtools should be handy.

Keyboard via usb with the froyo roms?

Has someone experiences connecting a keyboard or other usb devices with the Rk2818-Tablets?

I want to try it with my msi air keyboard.
[Android Software/Hacking General [Developers Only]] KeesMoer:
Thanks all! Screen calibration?

Thanks all, and especially the makers of the Froyo rom images! I recently bought a cheap Odys Genesis, upgraded it to the Froyo v5 as mentioned on the first page of this tread, and it works great! Much better than the original software, and good Android market support. Happy! :D

A minor issue: the touch screen calibration is a bit off on one side of the screen. Is there a way to adjust the screen calibration, and if so how do I activate it (not an Android expert myself)? Found no clear answers in this tread... :( Is there a recommended app, or even some manual method?

Kees.
[Android Software/Hacking General [Developers Only]] JDfense:
As far as I understand this thread is there no solution for the bad display calibration, but the older and wiser Members hopefully work on this weakness in the froyo and gingerbread roms.

I use the froyo v5 with odys genesis, too.
[Android Software/Hacking General [Developers Only]] DaremoS:
See this http://www.youtube.com/user/birdiebnl?blend=14&ob=5#p/u/0/f1BGX_msQaM

[Android Software/Hacking General [Developers Only]] DaremoS:
:D ... don't be so pesimistic... Majstor have a TS calibration working in Froyo v6.

I just need to turn it to work in Froyo v5 :(

I've spent too much time in GB for RK2818 :rolleyes:
[Android Software/Hacking General [Developers Only]] DaremoS:
@fun_ (developer of GB for KR2818)

For the moment some thing aren't working fine due to the use of memory.

Available memory is around 162 mb... GB use it entirely... Froyo goes barely above 100mb.

I don't wanna be pessimistic, but I have seen the problem with the calibration in a lot of threads with other tablets and there were not always a solution.

But DaremoS, your forthcoming gingerbread will be shure the finest bread I've ever seen:D and Majstors v6 will finaly do the trick to be stable.:cool:

I've tried to get the v5 smaller by taking out google maps. soundrecorder, talk, etc.,. No need for this stuff I think, but my first attempt was at last a piece crap.:(

Now I think, I have to learn more basics about the folder and files in the system.img. I haven't found any helpful documentation so far and reading a handbooks of Linux, Java and android will be useful but hopefully won't required.
[Android Software/Hacking General [Developers Only]] DaremoS:
Maybe you forgot to sign the new boot.img or system.img.

[Android Software/Hacking General [Developers Only]] JDfense:
No, that was not the problem. I could flash my rom, but it was unstable. Maybe it is not enough to take apk's out of the app-folder and I don't know how the google apps work together.

[Android Software/Hacking General [Developers Only]] DaremoS:
You're right. There are some interrelations, for instance: to put in work Market you need at least 4 APKs, then if you remove one of them it will spoil its functions.

. GoogleServicesFramework.apk

Don't try too much! I've burned my prestigio with xtreme OC when i tried to install Honeycomb on it!

So as an info the OC speed should be at max with 700-800MHz.

And remember to watch out for temperature, it's the same as if you're OC-ing an laptop or similar. As no fan is existant in this devices, OC is pretty dangerous!

Do it at your own risk!

pmp3084b

Hello I'm using pmp3084b for some time now , I triad all firmwares from this thread and here is my personal opinion:

-PMP3084BRU_FW_V2.1.13.zip is best firmware , only thing that I'm missing in it is support for feedly(I'm using just reader instead). I really don't understand why people insist on froyo , it's more important to have good firmware.

Bad thing about device:

-Slow CPU.

-Resisting touch screen in combination with slow CPU produces unwanted behavior like selecting things while scrolling.

-Bad games performances due to bad or no GPU.

Good things about device:

-Good screen.

-Good for reading and movies.

-Great sound quality , its better than IPod or my personal PC, this is really strange and make it worth money I spend on it(around 140 Euros).

Currently I'm waiting for Prestigio pmp5080b and if sound quality stays same and improvements be good I will buy that one.

Best regards to everyone.
[Android Software/Hacking General [Developers Only]] DaremoS:
This is the principal reason to use another version of Android... each new version have improvements (and more demands too).

Froyo (2.2) is full of extra functions compared with Eclair (2.1) which is more funtions with the same or a bit better speed.

I'm working right now in Gingerbread (2.3.x actually using 2.3.5) which is known as a rewritten code in order to speed up the firmware.

Version that I'll post soon have TS-calibration, accelerometer working (Thanks to fun_)... but more than that:... a fascinatiing speed which leaves all previous versions behind.

BTW all related with Flash memory and sdcard have been succesfully solved!. Includes market and Google apps working.

It's only pending graphic hardware acceleration... I'm sure that it will be solved soon.

Happy weekend and God Save The Queen!!!

[Android Software/Hacking General [Developers Only]] Iknownot:
It is the most stable firmware and compares well in speed with Froyo releases available here, I'm also back on 2.1.13. This is probably the last Éclair release, so it would be great if someone could do a version with the market and updated YouTube apps.

I got my OTG cables yesterday, but have had no luck connecting anything neither to Froyo v5 nor the 2.1.13 - tried BT dongle, mouse, keyboard and 2GB USB flash drive - don't have 3G dongle atm, trying to find Huawei E1752 to borrow for testing.

Example:

AFPTool -info update.img	Show file info

I'm impressed about the benchmarks, but I remembered the eclair roms not faster than froyo v5. Okay, benchmark tests - face the technical facts.:rolleyes:

Your wish after a final customized eclair rom won't be necessary.

Maybe try to be a little patient. There are new versions of froyo and gingerbread in the air. If not, I will try it with eclair, but at first I have to read a little bit more about customized roms. I don't want to brick my toy.:)

[Android Software/Hacking General [Developers Only]] Iknownot:
The lack of speed improvements in Froyo may be down to the kernel version, after all this device is using 2.6.25 which I believe was used by Android 1.0, according to Wikipedia: Éclair - 2.6.29; Froyo - 2.6.32; Gingerbread - 2.6.35.

We have customized 2.1.12 firmwares (haven't tried any of those yet) here, but stock 2.1.13 is better than stock 2.1.12, so there could be a custom version of this as well. I will be waiting for the next Gingerbread release and will try it out for sure, maybe it can make some use of the USB port.
[Android Software/Hacking General [Developers Only]] DaremoS:
Kernel is the link between the software (Android) and the hardware (RK28xx), if Rockchip (or someone else) release a Frozen Yogourt (froyo) or Gingerbread kernel for RK28xx we (us and CyanogenMod) gladly will use it. Meantime kernel 2.6.25 is the only available.

Concerning USB port: since froyo and ahead USB port for Android port have other functionabilities; is not anymore a plug to connect and disconnect, this is done by software (on or off storage) this is working right if our froyo posts.

It's even more complex in Gingerbread, happily for the user its alike froyo (on off storage), but for developers USB host function is included in code as other inputs in Storage setting (normal user forget this **** :))

Once again I have trouble with my PMP3084B. I couldn't flash my device via regular process (moving update.img to root and plugging out the usb cabel), as I get the "invalid firmware" notificaion. I tried to update via Tools according to instructions, but flashing always fails at checking flash 80-90%. And this happens with all ROMs (Official Prestigio v2.1.2, Prestigio from this thread, Prestigio clean from this thread). But the Next3 ROM works when upgraded via Tools. That also means that I am now stuck with Next3 ROM. Any idea why wouldn't my device flash with anything but Next3?

Plus, the Next3 ROM is not really rooted on my device. I cannot remove the apps with RootExplorer, nor can I change permissions. Superuser is installed, and the Mount R/W switch is visible from the RootExplorer, but pressing it does not nothing.

Below is the included RK2818 BatchUpgrade v1.23 LOG file for trying to flash the official Prestigio v2.1.2 ROM. (Failed at 80-90% of "Start to check flash data" porcess)
