How to make custom Firmware

SEE ALSO topic FAQ CUSTOMIZING FIRMWARE http://www.slatedroi...re/#entry449731

It can make everyone!

To make custom firmware you need to download this stuff https://docs.google....T21xMkR2VWF6MTQ

Troubleshooting: see here http://www.slatedroi...post__p__450241

Introduction to Firmware Structure

Spoiler

All new and future ONDA firmwares use u-boot loader, which allows easily to modify firmware parameters.

Stock firmware consist of two zip files and one scenario file:

- core file (kernel) g12refXXXXXX - open with 7zip
- patch file (update and rewrite core files when flashing) - open with 7zip
- factory_update_param (scenario) - open with Text Editor

Core file is compiled from stock Android OS and is adapted to tablet hardware.

Patch file allows quickly modify core files by adding applications, scripts, folders, build.prop parameters.

*Build.prop file (way: patch/system/build.prop) plays the same role as the Windows registry

THE ONLY ONE THING YOU MUST TO KNOW about FIRMWARE FILES

Spoiler

All files in firmware are signed! You need to sign modified files before to flash tablet.

Otherwise, when you had modded the files and start flashing, you shall receive errors.

1. Lets start

Spoiler

Download stuff and unpack programm _Update-Zip-Packager

Extract to folder _Update-Zip-Packager/placehere patch.zip

Extract to folder _Update-Zip-Packager/placehere/system file build.prop from g12refXXXXXX.zip

2. Changing LANGUAGE / TIME ZONE

Spoiler

When you use Chinese tablets, most annoying thing is LANGUAGE

Open build.prop with Text editor and change to your language / region / time zone lines:

ro.product.locale.language=
ro.product.locale.region=

persist.sys.timezone=

and save build.prop

After that use manual to make modded firmware.

2. Removing / Adding Applications

Spoiler

Another annoying thing are Chinese and (undesirable) applications

Open _Update-Zip-Packager\placehere\system\app and manually remove / add applications.

*Important. Added application name must do not have GAPS and DOTS (for example, Titanium Backup v.5.1.12 must be renamed to Titanium_Backup_v_5_1_12 or TitaniumBackup5112)

After that use manual to make modded firmware.

3. Just for FUN (boot animation & sound)

Spoiler

To quickly change or delete (animation and/or sound) use attached files.

 _BOOTANIME.jpg (35.4K)
Number of downloads: 34  _BOOTANIME.zip (4.96MB)
Number of downloads: 28  remove_BOOTANIME.zip (4.16MB)
Number of downloads: 19

Just extract the file to the microSD-card, and flash the tablet as usual.

 Bootanime.gif (137.4K)
Number of downloads: 28

Useful tools are here (to make your own animation and sound):

Boot Animation Factory http://forum.xda-dev...d.php?t=1678540
- to make bootanimation.zip

Format Factory (multifunctional media converter) http://www.formatoz.com/index.html
- to make poweron.ogg - cut/convert video/sound

or (better)

Free Studio (multifunctional media converter) http://www.dvdvideos...eo-software.htm
- to make poweron.ogg and convert video to .JPG - cut/convert video/sound

More will be added...

Thanks for this tutorial, do you know how we can change the Onda's stock recovery to ClockWorkMod 6.x?

Hi Jeff23ms,
Follow your instruction, I mode success FW (delete chinese app, change build.prop). Although I don't know how to fix youtube, could you help me how to mode to youtube working?
Thanks very much.

Hi Minh,

use these - they work for me

YouTube https://play.google....android.youtube

TubeMate http://m.tubemate.net/

If youtube can't start - check file system/etc/hosts

Remove all and write

127.0.0.1 localhost

Stock chinese firmware doesn't have Google sync.

May try custom firmware 1.4-EN03-40 or 1.4-EN03-40 with GO Backup Embedded

Thank you. Now I can fix youtube by mode "hosts" file. If I delete the "host" file in patch.zip and flash firmware again, whatever allthing is OK to fixing youtube and firmware may be flash without problem?

My mode firmware (for ONDA V712) almost is ok. Except google play is 101 error. Although I try delete account and make it again, it can not fix the problem. Please help me how to fix it.

Hi, Minh

I do not know the structure of ONDA V712 firmware. But, if V712 is dual core AmLogic, and last firmware is v.1.4, it will help:

- check - there are two hosts files in the firmware - one in the patch.zip and second - in another (bigger)zip.

Way the same - system/etc/hosts.

When you flashing your tablet, first of all files from bigger zip are flashed, then - files from patch.zip.

Files from patch.zip overwrite files from bigger.zip.

You can delete hosts from patch.zip, but in that case hosts from bigger zip will be flashed.

Do not delete hosts from bigger zip, otherwise you lost internet connection.

So, you can delete hosts from patch.zip, but in that case - you need to fix hosts file in bigger zip.

Do not delete hosts from bigger zip.

- "Google Play error -101" you can't to fix so easy. It doesn't connect to the hosts file.

To help I need to see your stock V712 firmware structure - can you send (attach to reply) screenshot ?

Hi Valkoz,
V712 is the same hardware of VI40 dualcore (Amlogic dualcore 1.5GHz, dualcore mali 400,..). Except LCD display is 7inch 1280x800 pixels, camera in back is 2.0.
This is link to V712 stock firmware v1.4:
http://www.mediafire...wro81q41dd4cpcd
http://www.mediafire...o771r7kz8lu2qw7

And this is tool to Joint these file http://www.jaist.ac....filesj/FFSJ.exe

I only mode a little as:
1. Build.prop: modify to Galaxy Note modern
2. Delete some app in patch.zip

I also try to copy google play.apk and googleframework.apk from xda and mode to patch.zip, but it's have problem with "Error retrieving information from sever.[RPC:AEC:0]".

Hi Minh,

I downloaded yesterday V712D-V1_v1.4 firmware (right ?), and sent to you private message.

But your comments are blocked, maybe the message is unreachable to you.

To modify firmware, answer pls:

1. language

in which country you live - Vietnam ?
Can I use
ro.product.locale.language=vi
ro.product.locale.region=VN
persist.sys.timezone=Asia/Bangkok
Vietnam doesn't have special time zone yet for android (Asia/Ha Noi), so I can use Asia/Bangkok also GMT +7:00

2. Build.prop: modify to Galaxy Note modern

I advice you to use your tablet as Samsung GT-I9100 - in that case you can download much more applications from Google Play.

But as you wish - inform me pls which phone models do you prefer for your firmware.

3. All other changes are clear for me

Valkoz,
2 questions:

Do you know what files in firmware are responsible for volume buttons on taskbar.

How to make updater-script copy some files to data and media partitions.

Thanks.

Hi ramek,

if you mean graphics resource - check 12refM1005A1.zip/system/framework/framework-res.apk

framework-res.apk contains all drawable resources.

You must


- decompile it with Apk Multi tool (9)

- replace icons (png)

- compile again (11)

- sign (12)

Then

- use _Update-Zip-Packager to pack and sign 12refM1005A1.zip

More information you'll find at http://forum.xda-developers.com

Thanks for reply.

There are no volume buttons in framework-res.apk.
It's separate program.

Do you know how to make Update.Zip copy files to /data or internal SD partition on our device? I need exact commands that work on our device.

Onda uses u-boot loader and the commands are standard. To copy usually make a script (placed in update.zip or separate zip - for example copy.zip).

But explain,

- from / where you want copy (indicate paths)

- in time of flashing firmware or as separate command when rebooting

Thanks for your help. I mode success FW for V712 dualcore. After flash mode FW, google play will be error -101. I must remove account and restart V712. After that, I make new account again, then waiting for file download.

https://skydrive.liv...ANHaoUhmdQzUU58

Wifi signal may be unstable, sometime it disconnect when I using internet, youtube. Signal strength is slight weak. Could you help me fix wifi issue.
Thanks again.

Thanks again.

Wi-Fi in Onda tablets is one of the best. I used my tablet in 30-40 meters range.

To analize your wi-fi try this https://play.google....e=search_result

Also try applications which ping wi-fi network.

There are many reason for unstable wi-fi, mostly depend on your provider and cryptos.

Errors -101 - connect to malfanction of Google Play and Google Service Framework.

Try this http://goo.im/gapps or google apps from modded firmware http://www.slatedroi...post__p__418448

tried these commands and they did not work for me:

mount:
run_program("/xbin/busybox", "mount", "/data");
mount("ubifs", "UBI", "ubi1_0", "/data");
mount("ubifs", "UBI", "userdata", "/data");

copy files:
package_extract_dir("data", "/data");

In my zip file I have these folders:
data
system
recovery
META-INF

I need this to copy video codecs for MX Player to work.
MX Player does not look for them in /system/lib. The only way to make it work is to copy them to data/data/com.mxtech.videoplayer.ad/lib/.
Also I want to copy Nova Launcher launcher settings.

Hi ramek,

sorry for the late reply.

I understood what you want.

Simplest way for vi40DC is (as you use the ext SD-card in any case):

Spoiler

1. Create on your ext SD-card subfolders: _COPY/data/com.mxtech.videoplayer.ad/lib/

2. Use this script:

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

######### Copy folder "data" from ex-SD "_COPY/data" to /data
#########
mount("ubifs", "UBI", "system", "/system");
mount("ubifs", "UBI", "userdata", "/data");
mount("ubifs", "UBI", "sdcard", "/sdcard");
run_program("/system/xbin/busybox", "cp", "-r", "-f", "/sdcard/_COPY/data", "/data");
unmount("/system");
unmount("/data");
unmount("/sdcard");
show_progress(0.200000, 10);

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

It works for me. Bonus: You can easy to change yours apps settings w/o update.zip repacking.
