Odys genesis works with Froyo-Versions

I have an odys genesis and android 2.2x(froyo)-roms are working almost fine for me. With the froyo v5, I haven't much problems. Only the display calibration and the video performance could be better.

I have flashplayer 10.1 installed, but i can't see video on youtube...

So..can't understand..maybe prestigio has a different chip? :confused:
[Android Software/Hacking General [Developers Only]] DaremoS:
Rockchip doesn't need Flash ... can be installed but it will be a waste of space.

All concerning videos (including Youtube) is handled by internal Rockchip GPU.

This means that browser won't read Youtube videos (as it happens) or any other flash instalment.

Anyway the application developed by Android for Youtube will work flawlessly.

Prestigio and all the customers of Yifang M901 uses Rockchip RK2818.

Be aware that Rockchip is a special kind of chip, it's a chip of chips, so to say.

It integrate good components in just one chip.

RK2818 integrate ARM9 processor + DSP (CEVA MM2000) + GPU (unknown graphic accelerator). ARM and CEVA are known brands in its fields. This reduce costs but makes a chip less compatible.

Mora than that Rockchip uses a different type of ROM called CRAMFS which is RO read-only unlike other Android ROM which can be RO and RW. That's why lots of applications have to be treated in a different way.

To root a Rockchip requires a special treatment different than the usual Android stuff. Happily MajstorSpeedy deal with this very well.:)

Due to this is Flash have no effect in Rockchip, among other considerations..
[Android Software/Hacking General [Developers Only]] musedream:
Yep, the V5 works fine, just video performance aren't so good, according to your post.

That's why i reflash it with the original 2.1 FW

The prestigio 2.2 and the V6 return me lot of fatal process error...

Dunno why
[Android Software/Hacking General [Developers Only]] musedream:
Really don't know...i can't see videos, just listen to audio.

I use default prestigio youtube app
[Android Software/Hacking General [Developers Only]] JDfense:
Froyo v5 doesn't play youtube-Videos?

Okay, you are right. I've tested Youtube-Video with the Froyo v5 on my Genesis. Result: Videos don't start. The Youtube-Version in the system is 2.0.26 and the current version is 2.16.

Is it possible, that the Youtube app in the ROM is too old ?

Arnova 84

Is there a root version of the firmware Arnova 84, it seems to me that is excellent at Prestigio tablets, fast boot, stable, clean and faster than the original Prestigio firmware... I use it a week and I am pretty satisfied with it. ..
[Android Software/Hacking General [Developers Only]] DaremoS:
Yes... that's possible, we have been using the same ROM from some time now, then it's not a strange thing. But I don't use daily such version of Youtube. I use the last one which is available in the net.

It's possible to install a new version of some application on top of the old one (in this case Youtube 2.1.6 on top of Youtube 2.0.6) The device will run 2.1.6 of course. The old one will live in the device unused, using some space.

This is not as in normal ROM (non-CRAMFS: explained here where new applications replace old one.

Anyway a CRAMFS ROM is smaller in size than a normal one.

Okay, at first I've tried to install youtube 2.16, but my Genesis did not accept the installation. Is there a trick to get the newer Version installed? Or could/must we retrieve the old version at first?

[Android Software/Hacking General [Developers Only]] retamalesfda:
no root ... no market ... :(
[Android Software/Hacking General [Developers Only]] SamuEDL:
Can you do a test video to see how this firmware?
[Android Software/Hacking General [Developers Only]] MajstorSpeedy:
So, i've downloaded this FW and it is Eclaire ROM.

# Do not try to parse ro.build.description or .fingerprint

# end build properties
#
# system.prop for ARCHM901
#

I won't bother with flashing it to my device coz i'm focusing on the Froyo

builds for these devices.

I can make it rooted with no problems but i don't have the time to add market or such. With it you can use Blackmart, Aptoide or anything else. Currently I'm running Froyo_v6 with newest market app installed but i don't like it very much.

[YOUTUBE]5Pbo-d62ivY[/YOUTUBE]

So, the question is, do you really want to use older 2.1 android or you want 2.2 or even 2.3 on your device...

If you really want to have the rooted arnova84 version i'll upload it but it's not worth the bandwidth used because it's already been done with Prestigio, Genesis, Next3 Eclaire ROM's.
[Android Software/Hacking General [Developers Only]] DaremoS:
The only thing about this Arnova is that I feel that display movies better than all I've tried. If you have it rooted kindly upload it in order to check the module of movies.

Thanks in advance

PS. Do not waste time rooting it specially, as you are devoted to froyo right now.
[Android Software/Hacking General [Developers Only]] draxd:
Well it would be really nice to try new market but I think that most important is to try make that Froyo rom more stable and faster.
[Android Software/Hacking General [Developers Only]] Seven64:
so i just got a nextbook 2 off of a penny auction site for $3 :) how long does this thing take to search the root directory? im looking for a file because i think i am close to rooting it!
[Android Software/Hacking General [Developers Only]] Seven64:
so i just stumbled across this:

how-unpack-repack-custom-firmwares-rockchip-rk28xx

on androidtablets.net, and it looks like it may work. i have no idea what that is doing to my tablet tho. is that a really extensive way to root it? i have z4root, but i still can't do lots of stuff in terminal, download out of the updated market, download most things off the internet etc etc.
[Android Software/Hacking General [Developers Only]] miljanars:
I agree with you, not worth the effort, and certainly it is better to have a 2.2 or 2.3, but version 2.1 ... I just wondered if there might be a already finished root version of this rom, as it suits me more than the original version of the Prestigio ...

By the way, I tried the Gingerbread firmware, it seems that you've done a damn good job, so we impatiently wait the final version, and as it says Mr. DaremoS, do not waste time rooting it specially, as you are devoted to froyo right now.

Continue with your good work, greetings!

Trial: Change Youtoube in Froyo 5

Okay, I give it a shot. I want to fix the youtube video problem and maybe I learn a little bit about these roms. It's the first time, I tried to get a closer understandig of android firmware/ROMS. I'm a newbie so far.:)

By example, I tried to get more Information here:

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

Can I use this manual to change the youtube.apk in the system.img\app-directory with the current youtube.apk 2.16 or is it more complicated?

I want to be shure, that I am on the right path for a trial to fix it.
[Android Software/Hacking General [Developers Only]] Iknownot:
Hi, my first post here.

Got 3084B for few days and running the v2.2beta1 firmware atm, got several issues (I assume these are also present in Froyo v6):

- Rotation works with delay, was more responsive with Prestigio's 2.1.13.

- The battery indicator is not present when running on battery, wrong battery indicator shows up when charging (without the lightning arrow).

- Device cannot be shut down when charging the battery, it will restart instead. Connecting the charger to powered off tablet will turn it on.

- The Wireless & Network settings have nothing but two items for WiFi, there are a lot more options with Prestigio's 2.1.13 (I assume that I won't be able to use 3G stick, have OTG cable ordered, but can't verify it yet).

- Notification area is filled with radio icons on black background.

I have been thinking to try out Froyo v5 or the 2.3.4 Gingerbread beta v.2, but got to ask first about the Gingerbread...

The USB issue concerns only the USB mass storage capability, so the connected 3G sticks, USB memory sticks and other stuff will work?

You can still perform flashing from PC with the Rockchip Upgarade tool if you want to install another ROM or firmware?

As I have read that Froyo should give general performance boost of 2-5x compared to Eclair (and Gingerbread improved on the touchscreen keyboard and power management etc.) among other improvements, but haven't seen anyone verifying it here with these custom ROM's.

I ran two benchmarks on 2.2beta1, but haven't got anything to compare it against. I will post my results and maybe someone can follow up with their results for different ROM's and firmwares.

Prestigio PMP3084B

Firmware v2.2beta1

- Benchmark by softweg (the results are saved on SDcard in folder "softweg" as .csv file)

Total graphics score – 99,952286

Total CPU score – 283,35583

Total file system score – 50,512726

- RealPi Benchmark by GeorgieLabs

100000 digits – 79.44 s

I can't add links yet, but on levelx.me site the 3 Androids are compared on HTC Desire (Froyo update is official one from HTC, but Gingerbread is custom ROM from XDA forums), here is a summary:

Pi benchmark - Froyo is 2.5x faster than Éclair and also slightly faster than Gingerbread.

CPU - Froyo is 3.3x faster than Éclair and also slightly faster than Gingerbread.

GPU - Results not shown, but written that Froyo vs. Éclair "not much difference" and Gingerbread vs. Froyo "graphics performance is improved with smooth navigation and improved responsiveness".

RAM - Froyo is slightly faster than Éclair and also slightly faster than Gingerbread.

File system - Froyo vs Éclair results not shown, Gingerbread is 1.6x faster than Froyo

The FW got an root canal job

Yes, most certainly you are.

Just remember to make changes ONLY to boot.img and system.img or you'll be in danger of bricking your device if you're not sure what you're doing.

@Iknownot, Yes, you have right about flaws in my v6 Froyo update.

Soon it will be done right, i just need a couple of days at the computer (which is quite a challenge ATM.).

@miljanars, As i said, it's not a problem. Here's the rooted version of Arnova84 firmware

I have tried to install the Gapps but have done something wrong in the process so i'll leave it for now. I have rooted the original FW and have added TitaniumBackup to confirm the funcionality. So, have fun all! ;)
[Android Software/Hacking General [Developers Only]] miljanars:

[Android Software/Hacking General [Developers Only]] JDfense:

[Android Software/Hacking General [Developers Only]] DaremoS:
Great... this will let me check video modules. I recall that open original system.img weren't possible.
[Android Software/Hacking General [Developers Only]] DaremoS:
It's great that a some new users is willing to put their hands in this lovely device.

Seven64, JDfense & Iknownot, I want to share with you something that took me some time to understand:

RK28xx uses a CRAMF system, which can't be modified inside the device.

Then rooting and some other optimization have to be done in your PC in ROMs that must be loaded back once ended (or tested in a emulator).

Therefore, lots of instruction to root an android device doesn't work in a RK28xx.

Modifications can be done in Windows or Linux, there are lots of tools to do this.

I share with you a kitchen that I found surfing the net, seems that is a Russian user: http://terra.rixo.net/~vadim/android_apps/firmware/

Good luck!!
[Android Software/Hacking General [Developers Only]] DaremoS:

That's not so, USB works fine, simply was hard to understand the way it work, please read this explanation:

[Android Software/Hacking General [Developers Only]] Iknownot:
Thank you for clearing that, DaremoS, I will flash the Gingerbread on my device today and leave some feedback and benchmark results on it later on.
[Android Software/Hacking General [Developers Only]] JDfense:
Thanks for the link DaremoS - interesting stuff. Could you recommend an android-emulator(WindowsXP) for our tricky device.:rolleyes:?
[Android Software/Hacking General [Developers Only]] Seven64:

Prestigio PMP3084B

Froyo v5

- Benchmark by softweg

Total graphics score – 81.701836

Total CPU score – 193.37917

Total memory score – 114.13607

Total file system score – 38.13245

- RealPi Benchmark by GeorgieLabs

10000 digits – 9.10 s

100000 digits – 101.54 s

So 2.2beta1 is somewhat faster than Froyo v5.

Tried also the 2.3.4 ROM but got a bit frustrated with it after the initial joy of having it running... couldn't install Market, inability to connect to PC, the screen rotation didn't work etc.

Don't have any comments on Froyo v5 yet, besides the fact that Wireless & network settings have only 2 items for WiFi and nothing else just like 2.2beta1 (I'm beginning to believe that the settings might appear once you connect 3G or BT dongle to USB), and screen rotation responsiveness is better than on 2.2beta1.

Flashing Froyo and Prestige ROMs to a Yifang M901

Hi,

Have any of you ever flashed Froyo versions and/or Prestige updates into an "original" Yifang M901?

friend of mine just got one of this and would like to update the OS but he is really afraid of bricking the device.

In case he does not like the new versions :-o , is there a way to return to factory system? Is there any way to download it somewhere?

Last question: If it´s bricked in the process, is there any way of recover it, like installing an older version using some type of service mode?

Thanks and keep up the good work!

Hello again, I've got the youtube-fix for froyo v5. On my Genesis tested - no problems so far.

Hey. I bought 2 Nextbook 2's today. They're all normal, and unrooted, and everything in between. Could I use any of the above ROM's (preferably FroYo) with them?
[Android Software/Hacking General [Developers Only]] DaremoS:
Great JDFense!!! you have enhanced that ROM... but... what where the problem of Youtube? :)
[Android Software/Hacking General [Developers Only]] JDfense:
very small enhancement in the v5

It was quiet simple. I've updated the youtube-apk in the ROM, because the original version was too old, I think and did not play youtube-videos anymore.

The current Version 2.16 of youtube play with the froyo v5 - loading not really fast, but I think, this is more a hardware problem of the weak WLan in the Rockship-tablets

You can't get the best for the small price and of course it's not a Samsung Galaxy Tab.:)

Maybe a better gingerbread mod would increase the performance of the rockship2818?!
[Android Software/Hacking General [Developers Only]] DaremoS:
We talk here of a device with 8.4" screen (800x600) Next2 its 7" (800x480).

Anyway in post 1 seems that there is a ROM for Next2.
[Android Software/Hacking General [Developers Only]] Lomby:
I assumed it was the original ROM that came with the device out of the box. Sorry D: To be clear, that ROM is FroYo, correct?
[Android Software/Hacking General [Developers Only]] DaremoS:
I recall that was a problem... great!! now you can update some other apps.

For you to know: in RK2818 system can't be updated, so updated versions of apps are stored in /data/app/ in internal memory, which is no-CRAMFS. so in the case of Youtube there where the old version is /system/app/ and a new version in /data/app/ ... with your new version you have save soma internal memory space, which is cool!

Nope its a whole ROM prepared by us. There is no Froyo for RK2818 8.4".

Barely a beta version in Prestigio, which is being cooked by MajstorSpeed.
[Android Software/Hacking General [Developers Only]] Seven64:
should that ROM for the next2 just do an auto update when i put it on my SD card then insert it into my tablet? if so, then its not working because my tablet tells me there is an invalid system file on my sd card and asks if i want to delete it

Update firmware/roms

The advice from Donaldj83 (Post #1):

»

move this to the sd card or the internal and update it

if it says invalid then use the directions and tools here

I use for my Odys genesis only the updatetool from PC via usb.
[Android Software/Hacking General [Developers Only]] DaremoS:
There are two ways of installation:

1. Software. The device recognize an upgrade: compatible brand / model with the firmware installed. Then device offers upgrading or deletion of the new firmware / ROM. Normally keeps user's data when accepted

2. Hardware. Different brand / model. Using the procedure described above by JDefense. User can tick an option in order to keep the data.
[Android Software/Hacking General [Developers Only]] Seven64:
that driver looks like its for the 2818 devices, along with the flashing program. mine is the 2808. either way, the flashing program cannot find the device and i got confirmation that the driver was correctly installed. is there a way to just install a clean android OS thru the SDK manager if i wipe the entire tablet? i can't figure out for the life of me how to get it to boot into recovery mode unless i put the stock update.img file on the sd card, then it will boot into recovery and install it.

Hi, All

I have bee reading through this thread the last few days and tried a few different ROM's best ones so far being the Gingerbread V4 only that the screen is upside down and I am unable to get it to right side up. And the cleaned Prestigio PMP3084B enclair version. Which works great but it is constantly wanting to OTA update. I was wondering if I missed the fix or either of these issues while reading through the posts or if there is one? Also I noticed there is an update to the gingerbread ROM from http://androtab.info/rockchip/firmwares.

The device I am using is NextBook Next3
[Android Software/Hacking General [Developers Only]] DaremoS:
1. That of OTA update: you'll have to remove a file named update.img from root of sdcard.

2. Indeed Gingerbread for RK2818 is the best in speed, look and functions ... BUT... still is pending implementation of hardware accelerator (video response is horrible, Youtube only in low quality).

Happily you commented new version posted by [[ fun_ ]] the initial creator, who have resolved a couple of issues: accelerometer and internal memory.

In a couple of days i'll post a new version including this fixes. plus something I'm trying to solve with video.

BTW is the rom I usually use. :)
