So will the nextbook 3 froyo rom work with the nextbook 2 since they look like their the same devices just different screen sizes.
[Android Software/Hacking General [Developers Only]] dying4004:
thnx for the reply but sad to know that. btw, does premium got 1 GHz ARM Cortex-A8 processor? is is awefully tough to compile a rom for premium 7 from the source code? cheers
[Android Software/Hacking General [Developers Only]] JDfense:
I don't know the Premium 7 - only reed the technical sheet.

If you find no custom roms for the Premium 7, I would search for a cyanogen-project for ARM Cortex-A8 or look for the Archos 10.1 threads with the similar processor. Maybe you find there some help.
[Android Software/Hacking General [Developers Only]] Ashtonj1:
Allright I got froyo on my nextbook2, I just built a custom rom using your froyo v5
[Android Software/Hacking General [Developers Only]] SamuEDL:
Us raise your rom of froyo
[Android Software/Hacking General [Developers Only]] donaldj83:
good job ashton play around with it if it works ok upload it to megaupload and give us the link ill add it to the main page for the next 2 users
[Android Software/Hacking General [Developers Only]] Ashtonj1:
So far all is good i've only had a few issues which im trying to figure out, one is when I plug in an sd card it mounts then unmounts automatically and the other is the screen is upside down (which doesn't matter to much since the auto rotation but a few apps don't auto rotate).

Edit: I just found an error in the log for the SD card and it is also doing the same for the internal flash storage. it says "Preparing SD Card" then it says "SD card safe to remove"
[Android Software/Hacking General [Developers Only]] DaremoS:
So we meet here pal... as you see I haven't posted anything since some time dealing with the damn hardware accelerator and Wifi of 2.3.1
[Android Software/Hacking General [Developers Only]] donaldj83:
any one have any luck getting flash to play on this thing
[Android Software/Hacking General [Developers Only]] DaremoS:
That's because RK2818 have flash in the chip.

If you see android code it's picked flash from the chip:

# for adobe reader mobile
export RK_ADOBE_DE_MOBILE 1
export RK_ADEPT_DEVICE_TYPE mobile
export RK_ADEPT_DEVICE_NAME NextBook
export RK_ADOBE_DE_ROOT_FOLDER /flash
export RK_ADOBE_DE_DOC_FOLDER "/flash/Digital Editions"
export RK_ADEPT_ACTIVATION_FILE /flash/.adobe-digital-editions/activation.xml
export RK_ADEPT_DEVICE_FILE /flash/.adobe-digital-editions/device.xml
export RK_ADEPT_DEVICE_SALT_FILE /flash/.adobe-digital-editions/devicesalt
export ADOBE_FONTS_DIR /system/fonts/adobefonts/

There is no need of other flash, in the device. Other problem is if the apps (browser) uses this flash.

cyanogenMod7 for odys genesis

Anyone interested in cyanogenMod7 custom rom for odys genesis based on fun_'s cyanogenMod7(gingerbread 2.3.5)?

content:

-last odys genesis stock rom replaced with fun_'s cyanogenMod7

-with complete set gapps

-with fixed accelerometer

+++

-find no problems with the display calibration

-small, fast and beautiful

-nearly stable

---

no video, except youtube(no HD) so far I tested it.

By the way I think, it should run on Next3/Prestigo, too.
[Android Software/Hacking General [Developers Only]] Ashtonj1:
Do you think it would run on the next 2 if ported correctly or is not fast enough?
[Android Software/Hacking General [Developers Only]] JDfense:
Honestly, I don't know. Do you tested some of the roms here?

I have tested nearly all roms in this thread. The last eclair is stable, fast and included video, maybe the right one for your next2, but the cyanogenMod7 has more functions and it is faster on my tablet. Froyo v5 is very functional and fast too, as long you don't install a lot extra apps, but the calibration costs me on the keyboard sometimes all my patience.
[Android Software/Hacking General [Developers Only]] Ashtonj1:
I think I might just flash back to 2.1 that let's me use my SD card until I can get froyo or gingerbread to work completely. And if you don't mind could you send me the cyanogenMod7 rom?
[Android Software/Hacking General [Developers Only]] DaremoS:
Congrats JDfense!!!... that ROM is quite good... I have also a 2.3.1 which can play movies... but have a problem with Wifi that I'm trying to fix.

I think that you can use fun_ calibration in Froyo v5... let us know what happens.
[Android Software/Hacking General [Developers Only]] JDfense:
Okay, I will post it now, no risk no fun, but be careful.:D
[Android Software/Hacking General [Developers Only]] JDfense:
Thanks, but better test it first. Maybe you find some trouble in it. By the way, I don't think, that I can transfer the calibration to froyo v5, still have to learn more about it. Maybe we could learn how to use your gingerbread 2.31 to fix the video problem in fun_s system.img or we have to wait on the next version of fun_.

cyanogenMod7 for odys genesis/PrestigioPMP3084B for testing

Okay, here it comes.

--------------------------------------------

cyanogenMod7 custom rom for odys genesis based on fun_'s cyanogenMod7(gingerbread 2.3.5)

http://www.megaupload.com/?d=8ZQBTZPC

content:

-last odys genesis stock rom replaced with fun_'s cyanogenMod7

-with complete set gapps

-with fixed accelerometer

+++

-find no problems with the display calibration

-small, fast and beautiful

-almost stable( in standby crashes rarely)

-working google browser

-working google sync

---

-no video, except youtube(no HD) so far I tested it.

-no usb disk or keyboard

By the way I think, it should run on Next3/Prestigo, too.

---Solution:rarely crashes---

1. If I switch off auto-rotate screen, I got no crashes anymore.

I use the fix for accelerometer adjust with one line in the built.prop:

sensor.accelerometer.invert_x=1

2. switch auto-rotate on again, changed the lock widget and finally no crashes anymore

3. Conclusion: Try out the settings/display and lock widget adjustments, if you have crashes in standby-modus.

4. Have a nice day.:)

----------------------------------------------------

Here comes a Prestigio(2.1.14) based version of cyanogenMod7

http://www.megaupload.com/?d=CQBIKP7C

content:

-Prestigio stock rom replaced with fun_'s cyanogenMod7

-with complete set gapps

+/-

I don't how good or maybe bad it works on Prestigio PMP3084B, because I have only an odys genesis. The calibration is different,

and works on my tablet not so good as the odys stock rom, but maybe its exactly right one for Prestigio. Feel free to test it.

Every feedback will help to make it better!

[Android Software/Hacking General [Developers Only]] donaldj83:
let me reiterate on this... im in no way talking about the flash as in memory storage or adobes book reader. im talking about the adobe flash player 10.1or higher or even flash player light it dosent matter. and i understand they made it to only work on the cortex8 chip or arm7 and ive tryed a number of ones that were hacked for the arm6 chipset to no avail (browser crash) but i figure we have a few smart people on this forum so im hoping maby some one has found one or tweeked one to work
[Android Software/Hacking General [Developers Only]] Quadliese:
Hello people, am still new here and I do not know much about Android. My English is not good. I hope you can help me. I Odys Genesis with ODYS_Genesis Firmware_v1.3.4-SD. Search firmware 2.2 with Froyo. Should be able to run stable.

Thanks for help :confused:
[Android Software/Hacking General [Developers Only]] JDfense:
If you want froyo, than I would recommend froyo v5 from Post #1 or with fixed youtube from post #516. Stable will be relativ for custom roms. The question would be: Is it stable enough for you?

If you want to write a lot with your tablet, than Froyo is in my opinion by now not the right stuff. The keyboard is a little bit difficult to handle.

Use the original update tool from the Odys homepage to flash and read the manual before.

And finally welcome in the world of custom roms.:)

[Android Software/Hacking General [Developers Only]] JDfense:
Yes, your are right, but no google sync. If you don't need...
[Android Software/Hacking General [Developers Only]] DaremoS:
What you have to do is to take kernel.img, misc.ing & recovery.img of your device... and use boot.img & system.img of any rom posted here to have your own rom suitable for your RK2818 7.0.

I know is complicated... but that is how this work.

BTW RK2818 CAN'T be rooted inside of device. Must be done outside.

You have some resources in the site of your device... and very good resources.
[Android Software/Hacking General [Developers Only]] i004909:
Hi. Thanks for super updates, I'm really happy to get Froyo on my PMP3084B. Everything works OK (had some headache with SD card but viola it suddenly worked.

@ DaremoS - You are making me drool with the info about your GB ROM with everything working (maybe except video?) and saying it's soooo super fast and great.

Please, please, please can you post it and I'll gladly test for you? Can't get the v4 you mentioned a few pages back downloaded from mega... and don't think the v2 on the front page with the long 'not working' list is the right one to download...

Thanks again

Next3 is bricked...

Ok, so someone suggested I return my Next3 (Which I can't).

1. Is there a Recovery Mode ?

2. Is there documentation on how to open this thing up? (Short Nand Chip)

3. Is there any way to NVFlash it?

4. Can someone help me? I'm sure others have bricked this thing and would be interested in knowing how to fix their $200 paperweight.

I (And I'm sure lots of others) would really like to know some answers to these questions...

Thanks in advance !
[Android Software/Hacking General [Developers Only]] DaremoS:
1. I'm sure that's possible to recover.

I. clip method in the hole of the rear (of the device)

II. with the device switched off press down arrow and plug USB... your pc must sound... then you can go into hardware method of flashing (from first post here http://www.megaupload.com/?d=X5J1GIDD). This is recovery method of RK2818 devices.

2. To open the device (no way pal!!!)

3. NVflash!?... maybe is what I explained above

Let us know
[Android Software/Hacking General [Developers Only]] DaremoS:
I've leave Gingerbread 2.3.5 for some time now... I'll take it back now that there is someone interested. Let me check in what was I ... :o
[Android Software/Hacking General [Developers Only]] DaremoS:
Gingerbread for RK2818 various ROMs

As requested here are the ROMs of Gingerbread 2.3.5 for RK2818 in 8.4" and 7".

Also I've added a ROM GB 2.3.1 for RK2818.

All this ROMs are just for testing purposes as I'm still working on them, beside my Froyo project..

GB 2.3.5 are fully functional (including Market) except for the infamous hardware accelerator. In version for 7.0 is not working camera either.

This ROMs might require a file in /DATA to adjust G-sensor. This file ---> local.prop. User will have to adjust it, changing binary values in at least two of four parameters.

Most of the problems of this ROM relies in the kernel. I've prove that using the kernel of PMP3084B thing go better. is the kernel used in 8.4" version. Using Next3 kernel disappear flash or SD.

A note: in this ROMs I've removed most of CyanogenMod stuff, because to deal with hardware accelerator requires to add lots of extra code lines.

Thanks to fun_ for his work and involve me in this project.

Gingerbread 2.3.1

I'v included a ROM based on N3NET to show how it works hardware accelerator in early versions of GB (very similar to Froyo)... but unfortunately this ROM have a problem with wifi, ancient problem that Chinese guys haven't been able to solve either.

This problem have been solved in a ROM of Breeze MW012 of AOC, which being so recently announced I haven't been able to get the firmware yet.

Links

GB 2.3.5 for RK2818 8.4" link

GB 2.3.5 for RK2818 7.0" link

GB 2.3.1 for RK2818 8.4" link

GB 2.3.1 for RK2818 7.0" (unstable) link

:):):):):)

I'll repeat: this is for test purpose and to allow others to contribute to the project, so I don't take responsibility whatsoever for brick some device (always recoverable anyway) and I won't answer complains.

:D:D:D:D:D
[Android Software/Hacking General [Developers Only]] JDfense:
Thanks DaremoS Einstein for the uploaded ROMs for testing them. I test the 8.4's on my odys genesis. I'll give you a feedback. Maybe there will be some gold in it.:o
[Android Software/Hacking General [Developers Only]] KeesMoer:
Thanks for CyanogenMod 7 on Odys; how to make /system rw?

First of all, thanks for this great ROM. Screen calibration is significant better than with Froyo; and system runs smooth on my Odys. And as I don't care about video too much, it not working is no great loss to me.

Few questions, though:

- First of all, how do I get write access to system (like /system/etc)? Doing things like

su mount -o remount,rw /system

does not seem to do anything :(, and still does not allow me to e.g. add a file to /etc (is /system/etc ). Would like to add bash and nano, and then being able to add something to a directory in the path would help.

- Secondly, the device now regularly wakes up automatically somehow. Screen goes on, can't see any activity though :confused:. Does affect battery life...

Help and suggestions would be appreciated! Thanks in advance, Kees.
[Android Software/Hacking General [Developers Only]] JDfense:
Thanks for your feedback, Kees, but most of the work was done by fun_ before.

Coming to your first point:

I can't explain the way into the system under linux, because I use windowsXP. I'm only playing once around with ubuntu studio - no fun with audio drivers under linux:mad:

For Windows, you will find under the following link a short description and the necessary tools:

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

In the system\data folder you can add or remove apk-Files how you like, but it could increase or decrease the performance of self brewed ROM. Few apk's will make your tablet unstable, so have nice trial.:o

Don' forget: Do only playing around with system.img and boot.img. If you follow this rule, you would minimize the risk to brick your genesis. These are words, I have learned from the wiser members around here:)

The second point make`s me little bit sad. I've have noticed sometimes the sudden wake-ups, but rarely. Influences with the battery load, I haven't noticed so far. More bothering are the crashes after some hours in standby, because the tablet needs then a reset.

I have no solution for both bugs. Maybe someone in the thread has an idea to this problems?
[Android Software/Hacking General [Developers Only]] DaremoS:
Just a simple sentence, as you seem to know of linux: system in RK2818 is CRAMFS!!
[Android Software/Hacking General [Developers Only]] KeesMoer:
Thanks for the answers (and thanks fun_)

Well, actually know not that much... I am a Linux user, but not really a developer. However, mentioning cramfs send me searching, and indeed it is now clear that with a compacted image/file system (even with 'RAM' in the name), random read/write is not feasible :(. Thanks for the hint! Apparently, the Froyo 2.2 v5 image I used (from page 1 of this thread) used a different file system.

Now to find an alternative way... For the moment, just placed them in the QuickSSHd dropbear directory, as when accessing via QuickSSHd it extends the $PATH to reach this location.

Edit: Just realized bash and nano are already included in this CyanogenMod by default; no need to install them myself like in my previous 2.2 ROM (which was smaller, hence the need for CRAMFS for 2.3).

Actually, I hoped to do this while working on the tablet, not by generating a new image and flashing either in XP or Ubuntu, just like I did on my previous froyo image (see above). However, thanks for the hint, as my original approach indeed will not work on de CyanogenMod image.

Might be related to apps having some timer (as e.g. to check email)? Guess I will have a different set of apps compared to you. And indeed, not all apps/apks work smoothly on the tablet, have some which even 'force close' although I see no reason for them to do so w.r.t. hw features they need...

Still, overall very happy with this ROM :D ! Regards, Kees.

hello,

you say, I can use any rom for RK2818 cpu from this forum but my device isn't 7" or 8", my device is 10"!

ok,if I can really use any rom for RK2818,I need your help!

Can you write me how can I install custom rom STEP BY STEP, and any link for tool and rom-s?!

I was rooted my device with z4root app.

How I can start recovery menu on my device?

6 mounts ago i was rooted my HTC cell phone and install CM7 rom.I find video instructions for this work on the web, but for my Prestigio pmp5100 I can't find any instruction for installing custom rom-s.

My cell phone works great with 2.3.3 CM7.

Anybody help me???
[Android Software/Hacking General [Developers Only]] JDfense:
I have thougt about the wake ups and crashes while the tablets are sleeping in standby. Maybe there is a context between both bugs and we have to search in the preferences. I think display- settings and energy-saving-parts are at first under suspence. Playing around could solve the problem.;)

Apk-Installations sometimes tricky. First time they crash, second time the run...:confused:

I would use an appInstaller for help as second chance. Some apps don't run from SD-Card. Keep the list of extra apk's small and beautiful, when you don't want to slow down your tablet.

And be patient, I believe the devs around here will bring sooner or later new brewed stuff into the light.:cool: Greetings, JDfense

Hi and many thanks to DaremoS

I upgraded my PMP3084B to GB235.

The improvement is fantastic. Just some impressions for others what to expect:

Market works fine.

I had SDCard issues with the previous firmware, now it is works for me.

The touch screen is really responsive, never felt so good before.

Gsensor works but shows everything upside down in portrait mode, and I did not find the file that I should edit yet.

In the settings menu the Cyanogen mod settings are crashing. It is a pity hence I prefer the menu bar on the top of the screen.

The adhoc WLANS are detected but I could not connect to my phone.

I can't use any rom for 8,4" devices!

today I am make update with RKandroidbatchudate tool and use rom for 8,4" devices and update is faild.

Now I can't power on my device or reset.

I try make update again with official firmware and I can't!

When I start update with "RKandroidbatchudate" tool there is message:

1.start update

2.start test device

and there update process stopped on 0% peocess and flashing yellow color!

Anybody help me!!!!????
[Android Software/Hacking General [Developers Only]] MajstorSpeedy:
Well kova555, you have bricked your device!

As we said 100 times b4, you should NOT use update.img made for different device as yours!

It WILL allmost 98% brick your device!

What you should have done is unpacking the official firmware for your device, unpack the custom 8.4' firmware and from it you take the boot.img and system.img and copy it to the unpacked original firmware folder and confirm overwrite request.

Then you pack it all up and than and ONLY than flash it to your device!

This way you keep your kernel but you change the system files.

If you change kernel or bootloader then you WILL brick your device if you don't know what you're doing!!!

Now it is too late for you but others should learn from this!

Flashing is not a game, it's your money at risk!

And a friendly advice for you kova555, return the device to the store and play dumb!

Say that it went off when battery was empty and when you recharged it the device would not go on! In this manner i have returned few tablets already... ;)
