[Samsung Galaxy Nexus] michaelmotes:
It's not a portable HD, just usb sd card reader.

With further investigation I have found that the problem might stem from the x-loader being mismatched to the kernel, which is part of the bootloader.
[Samsung Galaxy Nexus] michaelmotes:
I tried different bootloaders, but none made a difference.

Finally, I tried a different USB OTG cable, a slightly more expensive one, and it worked.

USB Modem Or Data Card support

I was trying with 3g usb dongle but it is crashing at 'mobile network'..
[Miscellaneous Android Development] JDfense:
Sorry, I don't know which 3g stick would work. All I know is, that you should plug it in otg-usb port.

Edit:

I forgot to mention, that I have taken out the phone.apk, because of the extra battery consumption.

Try first the original moage rom, here

Can you teach me to mod the rom? I want to mod the moage new rom. Thank you so much!
[Miscellaneous Android Development] stevemp:
modding rk2918

Ok, you have to work in Linux.

boot.img is a compressed file with a header(8 bytes) and footer(crc)

mkdir boot and copy boot.img to boot directory.

dd if=boot.img of=bootimg.gz skip=8 bs=1 count=30000000

This strips the header off.

gunzip bootimg.gz

This unpacks the bootimg.gz, make your mods now. Delete boot.img and bootimg.gz.

You need to reset dates after mods.

sudo find . -exec touch -d "1970-01-01 01:00" {} \;

Pack files back into newboot.gz.

sudo find . ! -name "."|sort|cpio -oa -H newc|gzip -n >../newboot.gz

Add crc so it will boot.

sudo ./rkcrc -k newboot.gz newboot.img

recovery.img is done the same way.

System image can be an ext3 or ext4. Mount image to modify files.

mkdir tmp and mount system.img to tmp.

sudo mount -t ext4 -o loop system.img tmp

Change to tmp directory and make your mods. Then unmount system.img

sudo umount tmp

This should get you started on modding. :)

If you have no experiences with linux, then you need some time to fight with the right system in linux.

On some days you would like to push your linux system out of the window.:cyclops:

[Miscellaneous Android Development] nikola987:
JDfense, tnx for the new 1.1 update :)

Anyway I have few problems. My google earth doesn't work and wifi keeps truning off when screen is off.

Also, I can't find options for live wallpapers anywhere.

Everything else works fine :)
[Miscellaneous Android Development] JDfense:
Don't know google earth, but maybe you need some extra gapps like google maps for the earth app.

I took out wallpaper stuff to spare the resources, but you can install from the market (play).

For wlan sleep go into the advanced mode of wlan settings and switch of wlan for sleepmode.

JDfense
[Miscellaneous Android Development] nikola987:
I can install any live wallpaper without any problem, but there is no way to select it anywhere. Option for this is completely gone from settings.

It's off by default :(
[Miscellaneous Android Development] JDfense:
Maybe I have an app to much deleted. I'll check this with the wallpaper.:cyclops:

And for what do you use voice search?

I took out all apps for which I see no use, but possible someone else need.
[Miscellaneous Android Development] stevemp:
Livewallpapers, voice search, and I think facelock also have been taken out of rom. Best to use Oma JB v1.2.2 World Edition rom if you want full Jelly Bean. --> http://crewrktablets.arctablet.com/

I use voice search all the time, use microphone in Google search bar and just say what you are searching for.
[Miscellaneous Android Development] nikola987:

Tnx, but oma's rom is too complicated for me.. I don't understand stuff with all fixes and kernels, or how to install them.

How to boot in clockworkmod?

Shut down tablet

don't forget to unplug usb

hold volume -

press power button until you see bootlogo

then leave powerbutton at once

It could be a bit tricky, but after some trials...:silly:

I don't know, if the oma nand to sdcard fix will work. You can try it or ask oma, what is needed for that fix.

JDfense
[Miscellaneous Android Development] aenima73:
Thanks JDefense,

I am not able to boot in CWM. I have done what you said, when I saw the bootlogo (the moage logo) I have release the power button then I released the volume- button but the tablet has started normally.

I have the Oma ROM and my problem is that I have accidentaly deleted all the launchers from system\app and now when system starts it gets stuck in the first window and I am not able to unlock it.

I don't know what to do, any idea?

If I am not able to recover my old ROM I have plannned to install yours.

Thnak you.
[Miscellaneous Android Development] JDfense:
Okay aenima73,

don't give up so fast. You have to keep holding the volume- button until you see the cwm.

If you have deleted the launcher, you lost the choice to change something in booted rom. Last choice could be the tool qtadb from pc, but your tablet must be in the debugging mode and all drivers must work fine. Thats a bit tricky too.

http://qtadb.wordpress.com/download/

JDfense
[Miscellaneous Android Development] aenima73:
Thanks JDefense but I ketp holding the volume- till the bloody main screen appears, no cwm.

The secuence is moage logo, Oma image and main screen locked but no cwm, volume- pressed during the 30 seconds of start.

I have also tried adb but I am not able to install the drivers, I have tried in 2 different PC.

I am affraid I will have to reflash.
[Miscellaneous Android Development] nikola987:
Try holding volume- before you press power button to turn on tablet, and keep holding volume until cwm starts. If that doesn't work then try it with volume+ :)
[Miscellaneous Android Development] aenima73:
I did it that way. I will try with volume+

Thanks.

[Miscellaneous Android Development] JDfense:
No, never before heard about your issue.

Possible causes I would assume:

-microsd with the videos damaged, nearly to die

-you videos have a bad/broken format

-nand flash needs to reformat

Great ROM JohnDoeFense,

I've love it, but in my case I have a unique problem (unique as I've not see a complain about it). My tablet Yifang M900HC doesn't show flash memory. I am able to watch it content in the tablet but doesn't appear when I connect to a PC thru USB.

I've tested several different kernels not succeeding.

It's something related to the Mayan End of the World?

TIA

PD:: Help I'm still scared!!!
[Miscellaneous Android Development] DaremoS:
One question for the user of this great rom:

Have you changed USB computer connection into Mass Storage?

The way to reach such option is Settings > Storage > menu > USB computer connection: is shown 3 options:

1. Media Device (MTP)

2. Camera (PTP)

3. Mass Storage

I've tested other roms of Jelly Bean: Xteam_4.7, Renegade (based on Moage 4.1.1) and this of my pals (also based Maoge), all with different kernels, and all have the same failure: flash memory (NAND Flash) appears clear on MTP, also in PTP (filtered for DCIM and Pictures) and DOESN'T APPEARS in Mass Storage.

SD Card appears in MTP and Mass Storage and NO in PTP (This normal)

I assume that is a problem of Moage. :rolleyes:
[Miscellaneous Android Development] JDfense:
No, I haven't change to usb mass storage. Maybe the usb app, taken from omas rom does that.

At first after flashing the devlopement options are not activated, afaik. For pc access you need to switch on them. Then play with debugging and memory type in the settings.

Last time I checked, I have access to nand flash and microsd from pc.

Maybe you get now your first trouble with win8.:angel:

JDfense
[Miscellaneous Android Development] JDfense:
One of these days...

Thanks DaremoSunshine,

it seems the mayas failed with their armageddon, but for shure someone else will find another last payday for the world.

I assume that the kernel is important for propper work jellybean rom, but I'm still not in the kernel edit business. Oma has a 'kernel guy' for his rom. Maybe we could ask him - astralix - about some issues.

[Miscellaneous Android Development] DaremoS:
Pals,

What are the tools used to disassemble update.img into boot.img system.img?

TIA
[Miscellaneous Android Development] DaremoS:
Daremo, use any tool by Wendal for instance "CWM_Extract_1.10.zip" google it!!!

Bye
[Miscellaneous Android Development] JDfense:
Hm. Wendal tools are a good choice for the one .img ROM to unpack and repack the five imgs you know from rk2818, only that system is not cramfs. Instead you have an ext3 or ext4 file, which you have to mount in linux.

This seems to be a zip file 'CWM_Extract_1.10.zip' with a recovery.img inside or it is a flashable zip from sdcard.

Hi,

I'm new on this tab, looking for a tutorial to flash this ROM from stock 2.3.

May someone can guide me ?

I have that one : http://www.somaxchina.com/productin...0Points_Muti-touch_Android_2.3_Tablet_PC.html

Thank you.

Edit : OK, I have extract the file, and think it will be OK, any advices ?

In the MoageRKtool.exe tool, the line "Loader" is not ticked, is it normal ?

Thank you.
[Miscellaneous Android Development] JDfense:
No, if you flash the rom the first time erase at first idb, tickle loader too flash the rom.

Here is a description in detail:

ROM Installation:

Here comes the how to install an unpacked ROM, means 5 img files flashing with the RKtool on your tablet. (Standard stock rom is only one img flashed with the RKbatchtool)

1. unzip the 7zip file, inside you find the unpacked rom deeper in the ROM directory and the MoageRktool in \u9gt2 Jellybean ROM 1.0 directory

2. Set your tablet with pressing the volume- and the power button into flash mode

3. Connect your tablet to pc, if your battery was before under 50% better plug the power supply cable too.

4. If you have never flashed a stock rom, you need to install at first the rk29xx device driver for your windows version 32 or 64 bit. You get them here on freaktab with the finless u9gt2 roms, from your tablets homepage or from many other sites in the internet with instructions to install

5. With installed drivers start the MoageRktool, in the bottom line you read 'Found RKandroid Loader Rock Usb', if not go back to step 2.

6. Press Erease IDB, you must wait on the positive message that the job is done

7. Check all boxes except of backup: Loader, Parameter, Misc, Kernel, Boot, Recovery and System have to be checked

8. Then flash the ROM into nand with the Run button

9. Finally you got a done message, hopefully without failure and

10. The ROM starts in the CWM (clockwordmod)

11. Press only power button to reboot

12. First start of the ROM on your tablet will begin, takes about 5 minutes and not more than 10

13. Ready - make your first step into androids world of the Custom ROMs

Hopefully I forgot nothing.

Jelly Bean

MTP replaces USB Mass Storage but you can choose which to use when compiling Jelly Bean.

<storage android:mountPoint="/storage/storage_internal"
android:storageDescription="@string/storage_internal"
android:allowMassStorage="false"
android:emulated="true"
android:primary="true" />

Jelly Bean 4.2.1 no longer supports external sdcard. :eek::(
[Miscellaneous Android Development] DaremoS:
I read you answer very very late (something is wrong with notifications of XDA) :angel:

The problem with MTP is that under certain circumstance is annoyingly slow to transfer files, as mi beloved porn movies :o

To do that in my CM10 oma based rom I use an specialized media manager (Media Center 17) which do the task faster.

That of JellyBean 4.2.1 is due to Google tablet that doesn't have this device.

Lost of vendors are implementing their own solutions for this issue. Samsung for instance.
[Miscellaneous Android Development] stevemp:
notifications

Notifications are not working for me either. :(

I don't use MTP much in Linux with G9, it exports internal sdcard as drive which can be mounted. The external sdcard I just use micro sdcard reader built into computer, faster. :)

The camera library (driver) should be in /system/lib and /system/lib/hw but you probably need to write a wrapper for the camera and compile a new rom.
