Lord... you just need to press down button and plug USB connected to your PC. To be sure put a clip in reset hole on back before.

Geeeeees!!!! VERY IMPORTANT!!!... DO NOT HAVE THE DEVICE WITH CONNECTION IN DC INPUT... this spoil this kind of connection of USB... believe or not... after connected to the PC you can connect such AC/DC plug.

Nothing should appear in tablet screen. ALL happens in your PC (announce of new device controller or a RKx device in device manager.

If this not work send the device to the provider... it has a serious problem.

Thanks !

the computer recognizes the tablet and says connected.. but the batch update program doesnot recognize it!!!! WTF???
[Android Software/Hacking General [Developers Only]] kova555:
Because your drivers isn't installing correctly to your pc.

When you press and hold volume down+on/off button then put cable to your pc and then windows automatically start installing drivers!

After instaling drivers batchupdate tool will recognize it!

Hey People!

First I have to thank you! With your help, my Odys Genesis is getting better and better, i never tought i would become such a good tablet for this price!

But one question i have, i installed the CyanogenMod on my genesis and now i would like to kick some of the system apps. Can someone help me with this? Because the normal ways i know doesent work because of the filesystem is read-only. Thanks!

I'm German, so dont worry about my english ;-)

Edit: Another question, is it possible in any way to overclock the CPU?
[Android Software/Hacking General [Developers Only]] rainasmoon:
how can i deal with the brick tablet?

many many thanks to pj2makr & Dfense100, i received your email.

then, i updated my nextbook2 through RK, when it said successful, i reboot it, but it got no reaction. when i pluged the usb cable, the computer got no reaction, i am sure i use the right rom. but why? what i missed?

i think i brick my tablet, what else can i do to unbrick it?

Guys how Can I overclock my tablet Prestigio PMP3084B, because when I'm using Overcloking widget I can't do overclock because I'm getting message: You are not root or something like that. I have rooted rom + su (z4root + su). I think thats is Kernel because in one programm I saw information that the CPU is controlled by Kernel. So how can I change Kerenel or is there any Kernel for my tablet ?
[Android Software/Hacking General [Developers Only]] JDfense:
What I understood:

you take one of the roms in this thread, upgrade with Rkbatchupgrade, the upgrade-tool responds Ok - no failure.

Then you have to start the tablet manuell and you got no reaction?

After flashing, the tablet should start once again without your help. That sounds strange.

Have you tried the reset button?

Which rom have you flashed?

---------- Post added at 08:27 PM ---------- Previous post was at 08:15 PM ----------

You better read a little bit about the RK2818 and android before .

For changing your rom look here:

http://wiki.archosfans.com/index.php?title=Archos_7HT_Modding_modify_update.img_Windows

and read fun_'s thread:

Be very careful, because bricking your device is possible and easy.:eek:

[Android Software/Hacking General [Developers Only]] mieszkos_x:
JDfense maybe u know answer for my question?
[Android Software/Hacking General [Developers Only]] JDfense:
I remember you possible use only linux?

If not, with windows, you can edit the system.img\built.prop with NewTuxFlash after unpacking with afptool. NewTuxFlash is unfortunately in german. Don't forget at last the rkcrc.exe before repacking your customized rom.

I don't have any experiences with overclocking the rk2818 devices, sorry.

I read not much about it.

I don't believe that overclocking could increase our tablet performance very much, but it is another possible way of bricking your device.:mad:

So be careful;)
[Android Software/Hacking General [Developers Only]] estugarda:
Well, thanks for your advice, but I have solved the problem. I managed to install it via BatchUpgrade tools on another computer. I have no real explanation why it wouldn't work on main rig (AMD Phenom X4 Win7 x64) and would work on my laptop (C2D Win7 x64), but it works now. And thanks to donald for his cleaned up version of the Prestigio ROM. It works great and it's faster without all the bloatware. Hopefully he will be able to solve the system access problem. We should all try to help him...
[Android Software/Hacking General [Developers Only]] taikyosan:
Can you describe the process, or name of tool used to do this? Is it specifically called BatchUpgrade?
[Android Software/Hacking General [Developers Only]] estugarda:
Yes. I used the instructions and the RK2818 BatchUpgrade Tool v.1.23 from the link donald83 provided in the first post:

well dav got back to me on the rw system problem he said

"the system partition is a cramfs image, thus read only. You need to either create another system partition when flashing, or use aufs to mimic a read/write system. "

now they used the aufs on a craig witch is also a rk28xx device now im looking online and theres not much info on how to do this so im looking at there rom and trying to do what they did but please if any one has any idea how to do this or can do this i could use the help

[Android Software/Hacking General [Developers Only]] estugarda:
The similar thing happened to me with my first Prestigio PMP3084B. Luckily it wasn't me who was trying to flash, but local service center. I couldn't flash it on my own with official v2.1.2 update.img+unplug usb procedure. Many people actually can't. Some say it's the porblem with the update, and some say it's the hardware.

I didn't want to take risks, and so I brought it to the local service center for update. They tried multiple times and device broke with similar symptoms as yours. It's most probably a fussy hardware all-around. Later I got the info form the service center that they are flooded with PMP3084Bs with hardware problems, mostly due too fussy assembly. Things like loose connectors and stuff.

I didn't have the box with me (although I had it at home) but they insisted to have my old box before they will give a new device. I believe this is illegal actually (not 100% sure though). So I insisted on that, and I got the new device without the box immediately. So you should try to insist too.

Even with my second PMP3084B device, I was unable to flash with official update (v2.1.2) via update.img+unplug usb procedure. After many tries, I managed to update via RK2818 Batch Upgrade Tool. So there must be something wrong generally with this hardware...Well. It's kinda cheap.

I must admit that I never heard anything about the apps maximum size on any android device. I'm new in Android world, so I might be wrong. Both my PMP3084B tablet and X10 can install apps bigger than 10MB. Could it be that there is something wrong with the APK files?

Looks like the RU firmware (PMP3084BRU_20110422_V2.2.9.rar) has some improvements - more default apps, including Vending.apk (Android Market) and more, some libs were removed, but I'm not sure if it affects functionality.

[Android Software/Hacking General [Developers Only]] MajstorSpeedy:
Well, for general info, it is not required to rkcrc "system.img" it is only required for "boot.img" (i have tried to left that out too but it leads to an infinite boot-loop)! So, if you only make changes to an "system.img" then you can repack it without any changes to crc.

@miezkos_s :

Don't try too much to overclock an RK2818 device, it will lead to a burn-out!

I've learned it the hard way. In my effort to put Android 3.0 on PMP3084B I have oc'd the core to the point of no return. In other words, I do not know what teh hell i've been doing... So the fact is: Leave it! It is ok as it is. Tinkering with the kernel is no good for amateurs like us. Fun_ is real dev and he understands how RK2818 chipset works and i doubt that he would try to oc the core of this device, I'm on the other hand only a dev wannabe with big aspirations and i have bricked a few tablets allready (5) so hear to my advice and let it be.

You can change whatever you want in system but you won't speed up your tablet like it's an tegra based one... If you want a fast device then buy Iconia 500 like me and enjoy the experience!
[Android Software/Hacking General [Developers Only]] Iknownot:
Actually its up to 640 MHz - http://www.rock-chips.com/product.php?id=76

EDIT:

Aparently BogoMips shows half of CPU frequency for ARM9 (RK2818) - http://en.wikipedia.org/wiki/BogoMips - the reading should be multiplied with 2, making the real frequency on these devices 622MHz.

Is this theory or is there a firmware version that can utilize the OTG capability on these 8.4" devices?

As far as I have tested (don't have 3G dongle yet) nothing works or is even recognized on the OTG cable. Also someone posted a link to russian forum thread for PMP3084B where coupe of guys are trying to get OTG working, haven't checked this thread in a while thought, they may have cracked it by now.
[Android Software/Hacking General [Developers Only]] DaremoS:
Well... Rock-Chips RK2818 (and RK2808) have among its features USB-OTG, as it can be seen here in this specifications RK2818 specifications by the Chinese manufacturer. Then was matter that some program take advantage of this, this was done in latest Android Eclair and Froyo and ahead, Gingerbread also have this option.

I do my successful test using a normal stock USB cable (the normal one provided with the device) plus a female-female USB coupler like this amazon.

When in Froyo, it's selected USB port = Host appears immediately a third storage called USB which access entirely the attached device, including an external disk. Then every device that behave as a mass storage will be accessed without troubles.

You're right, RKAndroidBatchUpgrade might not put problems if CRC of system.img is wrong... but NewTuxFlash will check this.

So it can be loaded in the device, that's why lots of Chinese ROM comes with wrong CRC rejected then by our useful and beloved German tool. :mad::mad::mad:

NewTuxFlash is used in lots of ROM, not only in Rk28xx, also in TV decoders and other instruments which require read-only memory.

Is Cell really enabled in ROM?

Hi guys. Can anyone confirm or help me figure out... is there a service for Cell or Phone somehow enabled in these ROMs for the PMP3084B ?

When I go to

CyanogenMod Settings -> Interface -> Status Bar Tweaks -> Alternate Signal Display

and change something, the little bars (or whatever option I choose) start displaying in the status bar again next to the battery - with an x over them as if to show no signal is being received.

Also, in Battery History, I find Cell Standby has used 60% of my battery. Obviously my PMP3084B has no phone (or Bluetooth, or Camera, etc. etc.) so I'm just wondering whether I could be getting better battery life and/or performance if somehow something could be disabled in the ROM? Battery life is pretty good IMHO so it's not a big deal.

I've used Titanium Backup to Freeze a few things like Voice Dialer, Camera because I think these will just waste resources if they run.

Thanks for any insight...
[Android Software/Hacking General [Developers Only]] mieszkos_x:
Thanks for reply guys. Well I looked in the threads but not a lot information about kernel's or how to changes kernels.

[Android Software/Hacking General [Developers Only]] Iknownot:
I will have to try out Froyo again one day, I did all my testing on the stock Éclair 2.1.13 and the Gingerbread from the first post in this thread. Which Froyo version did you use for your testing?

Mini-A plug in standard USB cable does not have pins 4 (ID) [in standard connection this pin is empty and has no functions] and 5 (GND) shorted like they are in the Mini-A plug of an OTG adapter... you set the tablet into Host mode manually, whereas connecting OTG adapter to the tablet should set it into Host mode automatically (pin 4, which is grounded in the connected plug, acts as a signaler to the tablet device, telling it to go into Host mode). So, despite the RK28x8 having OTG capability, I don't think it is implemented in these devices. If the OTG is disabled, then there is no chance of connecting any peripherals with Éclair, since there is no way to set it manually into Host mode. Not sure what else is included in "OTG", turning on the power for the periherals perhaps!?
[Android Software/Hacking General [Developers Only]] JDfense:
Thanks for the info, that there is no need for using system.img with rkcrc, but if I want to change my rom with newtuxflash I get problems without rkcrc.

You have bricked five?? tablets so far?:eek: I think, you don't like them;)

And Iconia 500 is a nice choice, but a higher price league. I think about Hannsspree Hannspad. Cruel name but the hardware is allright for under 200 Euro.

Re: debug.sf.hw=1 ?

Thanks for the extensive explanation; is quite readable for me. However, to be honest, I am more or less a beginner in Android, and I need more than just the question to verify an experimental test (see the original debug.sf.hw=1 issue) to go down this route...

I'll keep it in mind for when I have more urgent reasons, or when my stack of minor changes is long enough. Would have liked a somewhat more stripped version of Cyanomod in a more manageable (=writable) file system format like in the 2.2 ROM I used (apart from this, I am quite happy with Cyano 2.3.5). Or maybe someone can add some overlay file system?

Regards, Kees.
[Android Software/Hacking General [Developers Only]] MajstorSpeedy:
Well Hannspree is not a bad choice but i have been stunned by the speed of an A500 (in fact, I have exchanged it for a A501 that is now available in Croatia...). It flies literally! Anyhow, I have indeed bricked 5 tablets so far due to my own ignorance. As I said, I'm only a dev-wannabe and I have a lot to learn so I have bricked Point of view GenII 7", Prestigio 5070C (2 devices), Prestigio 3084B (2 devices). Last 3084B was not bricked but instead I have managed to fry the SoC alltogether due to a bad overclock effort...

Well, some ppl do never learn... lol

But now, I'm a lot more conservative in regard of flashing these (potential) bricks and I pay attention to every aspect of a new ROM.

Right now I'm making some efforts in visual appearance of Froyo ROM and i think that you'll like it alltogether! C ya all soon with new release!

Okay, Iwill keep my odys genesis safe for your next froyo release.
[Android Software/Hacking General [Developers Only]] fun_:
just FYI.

technically rkcrc is not needed for system.img/system partition. rkcrc is important for files/partition which is used by bootloader, i.e. kernel.img, boot.img, and recovery.img. parameter file also have (header and) rkcrc but it is added by AFPTool silently.

personally I never used newtuxflash so I'm not sure about it. probably newtuxflash doesn't know about rkcrc which exists only on products with rockchip(no relation to cramfs). there is another crc in cramfs so I guess newtuxflash complain about it.
