I would like to thank you all for learning about my Prestigio PMP3084B, but obviously I didn't learned enough. I tested successfully some of your custom ROMs and now I'll try on my own with the original Prestigio 2.1.15 first.

Aim: Get one or two apps deleted in system.img and fully rooted

I did:

- unpack original 2.1.15 with afptool: afptool -unpack update.img update

- decrypt system.img with rkdecrypt

- mount system.img in kubuntu: sudo mount -t cramfs -o loop system.img system

- create "work": mkdir work

- copy system/* into work: sudo cp -R system/* work

(some files in system/bin were not copied. I did this manually)

- delete apps for testing: solitaire and chess

- copy su-2.3.6.1-ef-signed.zip: su to work/bin and superuser.apk to work/app

- chmod: sudo chmod 777 work/bin

(sudo chmod 6775 work/bin/su and work/bin/sh failed)

- chown: sudo chown -R root:root work/bin failed

- create new image: sudo mkcramfs work system.img

- pack a new img:

+ copied the new system.img into unpacked folder "update"

+ afptool -pack update testing.img

- flash testing.img with RKAndroidBatchUpgrade.exe from prestigio's site

Image is flashed successfully and device reboots - unfortunately in Revory system v1.3.30 with the following: "E: Can't open /cache/recovery/command

Where I'm wrong?

Or does someone already has an original fully rooted 2.1.15?

(Donald's patched original is unfortunately not fully rooted)

-----

Deleting Apps with newtuxflashtools works great.

Full root access is still pending.

The sound is a known problem, but a small one. Install jukefox or winamp or which player you like from market. The standard musicplayer can play flac, but not mp3. There must be a failure. Right now I don't know how to fix.

The rotation in homescreen is a problem with the launcher 2. With the adwlauncher it would work, but this launcher is not so nice.

If someone knows how to fix this two problems, feel free to let us know, too:)
[Android Software/Hacking General [Developers Only]] jazzh:
OK. At first the sound didn't work, I chose reboot shortcut in the app menu, but still didn't work. Then after a few cold shutdown and wifi enabled the sound worked!!! :confused: Don't know if no-network was the problem or normal power up, but it's working now. ;)

I tnink this is the most usable rom for Prestigio so far, and I tried really a lot of them. After 3 months experimenting I finally spent 2x5hours in everyday usage, it was bought for this after all :o.

I can confirm this:

1. Wifi - perfect, in the margin areas, where previous roms (both official and nonoff ones) didn't. I played sky.fm int radio on 64kbps for 2 hours without a single drop!

2. Calibration - almost perfect, the same as in official eclair roms which worked best for me so far. I think it's the device maximum.

3. Market, google sync - excellent.

4. Battery autonomy - perfect, I calculated, even 10% better than the previous maximum result.

5. Font rendering - perfect.

6. BootUp and overall speed - fastest so far for me, faster than prestigio official froyo rooted and cleaned, faster than Eclair rooted or official...

If I could only solve these problems:

a) Home screen to be in portrait mode.

b) Volume shortcuts in taskbar, I didn't find this setting so far (can live without it though)

c) This is the most important and long term priority - 2 of my most used local android news apps are starting the master screen in portrait reversed rotation (upside-down, 180%) but when the detailed article is chosen then it can be rotated to correct portrait orientation.

Thanks to JDfense/Daremo for this wonderfull rom!
[Android Software/Hacking General [Developers Only]] JDfense:
Thanks jazzh. This kind of feedback help much to make a rom better.

For the volume are no buttons to get over the setting. That is a (small) disadvantage of gingerbread, I think. Use the dsp manager or another app.

This upside-down problem in some app is a riddle for me, too.

Is the market fast enough? For me it works on Genesis very slow. Maybe I change to the old market.
[Android Software/Hacking General [Developers Only]] jazzh:
I didn't notice any Market slowdown, maybe because I usually perform these actions: search for well known app, install, search, install... and have simultaniously several downloads and installations at the same time, so it's usuall for me not to have blazing speed :)

I will try browsing per categories later, scrolling and so on...

So... it would be nice :) if you could report here if any progress has been made on:

a) homescreen portrait mode and

b) upside-down some apps entry

problems...
[Android Software/Hacking General [Developers Only]] Scorp369:
I have tried the first rom on a NEXT3 and having same issues as with the original GB release.

The VideoPlayer app force closes. I have to use the movie app. Sound and video not synced when playing videos if I drag the slider to a new position.

Some apps not installing from Market, especially Aldiko free e-reader app. It downloads fine but fails to install.

Not seeing any major calibration issues with the first rom. Getting ready to test the second.

Second ROM same issues. I tried re-packing with my original Next files and have the same problems.
[Android Software/Hacking General [Developers Only]] JDfense:
It should work with your stock kernel.:confused:

In case of prestigio, I got only a good result with stock rom from eclare. If the next 3 has more than one kernel version, try the other ones.

My next release is coming soon - another gingerbread. Maybe this rom will work better for next 3.:)
[Android Software/Hacking General [Developers Only]] jazzh:
Will this next GB release of yours be worth of trying on Prestigio, too? :)
[Android Software/Hacking General [Developers Only]] Scorp369:
The eclare roms are the only ones that allow me to install the Aldiko app. I do not think that Next3 ever had more than the stock kernel released, the company firmware page never showed anything when I checked.

I repacked the Gingerbread releases boot and system image files with my stock image and have same issues. Also noticed the app wouldn't install with the froyo roms I have installed as well.

Thanks for replying and the custom roms.
[Android Software/Hacking General [Developers Only]] JDfense:
Is there any Next 3 user out there, who knows a custom rom that fits for next 3? What is the trick with this rk2818 tablet?

---------- Post added at 03:11 PM ---------- Previous post was at 03:08 PM ----------

Yes of course. It would be a question of taste. Both are Gingerbread 2.37. I will make a prestigio version, too. I will upload the rom for genesis later today, maybe prestigio comes, too.;)

[Android Software/Hacking General [Developers Only]] Scorp369:
The Aldiko problem is ginger related. Turns out you have to remove SD card before installing it. Still not sure about the default Video player. I can download another one.
[Android Software/Hacking General [Developers Only]] donaldj83:
i would like to find out how to edit the kernel.img im dieing to get rid of that goofy main screen but i havent found a good "how to" way of opening it and creating a new one is totaly out of the question due to my lack of time and knowledge i do know there are a lot of games out there that just dont support the screen size that we have. the developer is making them for phones not tablets ya know? but hey if you do figure out how to do it and are sucessfull at creating one send it over ill add it to the rom for every one
[Android Software/Hacking General [Developers Only]] KB112:
Sorry man, was helping my bro change his brakes last night. But I'll mess with it tonight. It does have an sd card in there. I'll let you know my results as my Dad needs it for his trip this weekend.

I've had no Market problems buddy. Well it would say network connection error a few times. But I'd clear they and it would connect fine. Downloaded alot of apps over a period of an hour plus.
[Android Software/Hacking General [Developers Only]] donaldj83:
well i pulled my sd card formatted it, then let android format it, then reflashed my nextbook to get the market going again downloaded like a son of a gun i kept my sd card removed the entire time i connected to my nabers network bc it was unencripted i disabled the ota updates and also the wifi sleep policy it lasted till late last night and when i woke up this morning its dead i just disconnected from all networks and rebooted and now trying the market fix rebooting and now reconnecting to the network and nothing... dose the same thing........... im about to fix it perminatly with a hammer gurr any sugestions at all would be grate....

some thing intresting to read

http://forum.androidcentral.com/htc...how-build-your-own-kernel-package-source.html

i was also looking at porting bc the cmp736a is a rk2818 device as well and i have installed that version to are device but the touch screens funky when you do, unusable due to the touch screen but dose work as a proof of concept and they do have a legit 2.2 version out there some one may want to look into that while im trying this out
[Android Software/Hacking General [Developers Only]] donaldj83:
i contacted prestegio in hopes to get the kernel sources legally there obligated to release them but well see what happens if any one else wishes to as well the more the merrier if you get it b4 i do send them to me i wanna try building a new kernel

Just a warning, Prestigio has awful tech support. I sent them an email about some firmware issues once, and got a blank email as an answer. I thought this was by mistake, and sent them another mail which never got a reply. Other people had such experiences as well, so better not count on them to assist you in any way.
[Android Software/Hacking General [Developers Only]] donaldj83:
ya i have those book marked but from what im seeing there is no way to decompress a kernel.img to modify it it has to be recreated using the original source http://forum.androidcentral.com/htc...how-build-your-own-kernel-package-source.html

thats what they say and i kinda figured getting the original source code from them is a long shot but it wont hurt to ask

btw im still experiencing market issues i still dont know what to do even asked on the development forum on here and im not getting any help

oh hey heres a nother kernel link http://marakana.com/forums/android/examples/111.html <<that sounds promising my weekends going to be swamped so i wont be around if any one makes any progress with any thing make shure yall post it for every one
[Android Software/Hacking General [Developers Only]] KB112:
This thing runs much faster/nicer rooted. Opera Mini runs speedy and is really smooth. Of course the lack of physical menu button makes some apps problematic. Like Terminal Emulator, you can't toggle the keyboard.

I couldnt get XDA app to work. It would load up then say I didnt have permission and an error would pop up. Any suggestions for a different keyboard? One with arrows would be nice. Or any other recommended apps for that matter.

I'm still having same issue , I reflashed it and again after hour or two i get download unsucessfull problem. On prestigio page there is another market application applib that use to work with my prestigio but it does not with this firmware , is there any way to make this aplication work ?

Please, Mr. Scorp369. Here comes the next rom for trial. Maybe this time with more luck.:)
[Android Software/Hacking General [Developers Only]] Playdoe:
wow JD thanks...okay so it seems that greta link "the collection" is updated versions,or might I say the fixed versions of the flash/firmware. So question. I'm about to try your latest one. The Gingerbread 2.37...on my Next3. Has anyone,or maybe you had any success with it on next3?

---------- Post added at 01:28 PM ---------- Previous post was at 12:41 PM ----------

hmmm...i've flashed my next3 to the latest version of your "collection" but seems I instead flashed it to the Odys version. Seems pretty cool and i don't mind it except the homescreen doesn't rotate? seems it's one way and thats that...other problem I'm encountering is everytime I try to download pretigio firmware...last one at the very bottom...megaupload tells me the files temp unavailable..any other mirrors where one can download?
[Android Software/Hacking General [Developers Only]] JDfense:
No, I own no next 3, but if you change your stock kernel.img. If you can't do that, upload a next 3 stock rom and I will see, what I can do.

Greatest problem is, that I can't test it before and you get lucky a good calibrated rom or a not bootable rom(a piece of shi..). Anyway you can reflash back to stock rom.

Next3 Success stories?? Flipped over here!!

First of all I want to thank you guys for your hard work and effort to bring us all these incredible tools. Honestly..you could've just upgraded your own devices and the hell with the rest of us...Anyway i wanted to know if anyone has had success with their next3's and which firmware you used. i love the Prestigio update...although (by mistake) I did the Odys one with Gingerbread 2.3 and it seems to work great. the only problem is that the "home screen" was always horizontal forcing me to contstantly turn my nextbook...although any other screen (past the Home screen) would flip along with my every move...now I'v also flashed the pretigio firmware and same problem. I honestly dont mind it and i know its a minor problem compared to the great advantage...just used to the "older view of things" Any ideas?
[Android Software/Hacking General [Developers Only]] JDfense:
Okay, now I have a test rom for Next 3 gingerbread 2.37 with the hvdwolf system.

GB.2.3.7 for RK2818 with Rockchip HW video acceleration working

originally posted in 2011.11.16 removed by fun_orders

FUN_, de original creator of the image, make a moderator remove it claiming that I've copied his files

Judge by yourself.

1. My ROM is working perfectly... while his ROM have the problem of BSOD (Black Screen of Death) which is device blocked after resume.

2. My ROM have flash support... fun: doesn't have it

3. My ROM work fine with USB HOST

4. My ROM play perfectly movies and music.

ok... its enough

fun_: FUKAUMI Naoki (naobsd) is a developer who can't accept that other do things better than him

he wrote this:

"I don't mind if someone uses my file. my files are free. I don't mind "who is number one!?" in this post here

crying like a crocodile... then going to moderators to make others work dissapear.

Fun_ it's not just a developer, it's a lawyer and the Spanish Inquisition.

If anybody is interest in a ROM that really work

MY ROM so called THE ROM pick it from here

rk28_7_gb7.verne.01

it's for RK2818 7", the first to play HW video in GB.2.3.4 and above

based on FUN_ CM7 for GB.2.3.4
[Android Software/Hacking General [Developers Only]] DaremoS:
Ok I've tested this rom of hdvwolf.

As expected, all work fine, is fast and doesn't have noticeable bugs

- keyboard is ok... IMHO... keyboard in mine work bad because I use a density of 152 instead of 160

Now the bad things

- mass storage screen doesn't appear (to change connection with PC) this seems to be an android bug.

- music and video doesn't appear in menu options, then music have to be played from File Manager.

Enhancement:

- Program recovery options to allow selection by buttons or joggle.

This have to be done in init.rc of recovery.img values 103, 108, 62 will work for odys genesis.

BTW I've noticed that you copy recovery.img from one ROM to another... am I right?.

I have no idea what could be the result of this... I do this in my beginnings too, and lots of people do the same.

Now I program recovery to use the options offered, so I keep original recovery.img.

My usual way to load a new ROM is by using the option of load "update.img" from SDCARD from that menu.

In most cases it keep user data.

good night and good apetit
[Android Software/Hacking General [Developers Only]] Playdoe:
Ok...so I ran it and seems to be running fine...EXCEPT..when for instance I launch a game no sound comes out...although sound does play with video. Funny thing is I have Moon+reader and it seems to play the books upside down...although I think that has something to do with the way I formatted the epub file. So besides no sound on apps (and I did try raising sound and enabiling it...to no avail) everything is okay. tonight i'm gonna test the froyo v.5. I hate to go back in time but it seems the best OS I've had so far was the Prestigio PMP...blah blah the one without the bloat before I was given these wonderful things to try. Btw JD and guys I unfortunately don't know the tech lingo when you say kernel this or that. I'm an intermediate...I prefer working at hacking games and making cracks for them..PC mostly. So pretty much a beginner when it comes to tablets...so keep giving me new versions and ill tell you what I get. thanks

---------- Post added at 09:21 PM ---------- Previous post was at 08:22 PM ----------

Okay so its the middle of the night and i have now tried ...officially 6 different firmwares on me next3. Pretty much fail...my last try was the froyov5 but that had a million apps that i didn't need and then the screen would rotate and not want to rotate back. the one you gave me for the nextbook 3 JD was perfect except for the sound issue. I can remeber that the "almost perfect" version I had was the very first Prestigio PMP 2.1.2?? ( not sure) but the one labeled *stripped of bloat*. Now if somehow we can start at the begining with that and add the cool cynogen stuff , i think we've got a winner...oh don't forget my sound and calibration please...thanks man. I've been up all night on this.
[Android Software/Hacking General [Developers Only]] incognito28:
I have a next2 to and I tried everything to try to up grade the rom. I tried every rom that was posted. I got either a blank screen, or a screen full of colors. I have the next2 that have the 1.5 loaded on it, and the rk280x drivers I think. I was hoping do anyone have the stock firmware that I can download so I can at least get it back to working order is possible thank you if you have it.
[Android Software/Hacking General [Developers Only]] Scorp369:
Downloading now. Will try to install and test some before bed. I tried the Froyo V5 but it had same install problems on Aldiko with or without SD card installed. And like the other person stated, all the home screens on the GB's are locked in Horizontal view mode.

Fixed the landscape rotation by de-selecting the 90 degree Accelerometer setting in the CyanogenMod settings. Tablet now displays home screen in portrait mode, Aldiko also displays my e-books correctly now. Had no problem with the USB storage when connecting to my pc. My media doesn't show up in the video or music player as previously stated. The sound is quite low, had to max it out under volume settings. Overall its pretty good. Especially like the calibration program.
[Android Software/Hacking General [Developers Only]] jazzh:
@JDfense

Does this mean that this last Prestigio rom of yours "gingerbread237hvd2 for Prestigio pmp3084" will posiblly layout successfully the homescreen in portrait mode, too? As the paralel rom did for the Scorp's Aldiko...

Or I figured out something wrong here...
[Android Software/Hacking General [Developers Only]] JDfense:
Yes it does the autoration correct on homescreen, because it has the adwlauncher with cm7 design instead of the launcher 2 installed.

---------- Post added at 07:49 PM ---------- Previous post was at 07:39 PM ----------

No I did not take the recovery from strange tablet, but possible can be a failure.

This is the normal combination for assembling:

kernel, recovery, misc from stock rom

system and boot from the developer

Is this wrong?

And I take only rkbatchupgrade for flashing. I find this way over the sdcard not safety enough.
[Android Software/Hacking General [Developers Only]] jazzh:
JDfense, I just flashed it, booting up right now, everything seems ok. I'll report on impressions. Thanks.
[Android Software/Hacking General [Developers Only]] jazzh:
Nope, no good.

1st boot was ok, I immediatelly unchecked 90 degrees accelerometter in CM settings and homescreen appered in portrait mode. :)

Wifi was ok, calibration ok, but no sound. Then all of a sudden the screen went black, when button pressed it shows backlight but the screen is still blank, then I punched the hole on the back to do a reset.

When booted up again, I inserted sd card and it freezed for a moment. Then it went to sleep mode and couldn't bring it back again.

So I guess a wake from suspend is not working. Possibly some setting in CM?

Going back to your previous GB rom now...
