Well, in my opinion, copying their custom firmware isn't the best thing, it would make more sense to modify ours to implement what's missing, if you have any ideas/comments.

Moreover, some changes mentioned on wanden website aren't very detailed (stuff like "Battery saving enhancements - Now your U30GT2 lasts all day") and may be just simple changes that could offer less than what is advertised...

We have custom firmware for the first 3 tablets from your list, the U9GT5 also, for the old RK3066 model, I need to check and make an update for the RK3188 one.

If you like our web site, applications and firmwares, feel free to support our site. Donations are used to pay the bills for our server hosting costs, development tools and purchase new tablets to support.

Yes you are right i will upload the other firmware to the tables and check them out to see if i have any ideas to add things.

Does iplayer work with your firmware

some of the most popular apps would make things a lot quicker for set-up a tablet if they where added in the firmware.

ie.

Facebook, Twitter, Dropbox, YouTube, A Free Office Suite, a really cool easy to use launcher.

Thanks

It is very interesting anyway, that as a reseller, they charge for updates, charge for free software, charge for open source.

Yes when you put it like that, they are being quite cheeky especially when they where charging £49.99 for it.

Also i have seen you mentioned in one of your other feeds that you can install default app in the app folder for make the right permissions to get them to work, can anybody tell me how to do this.

Using Restore in Rockchip Batch Tool is recommended as it does a quick "format" of the device prior to flashing ensure all the data is erased and you start from a fresh formated device.

Just copying an APK file to /system/app should be enough to install it as a system application.

is there any easy way of me including them in the Firmware install so i don't have to install the apks on there own so i can streamline the process of installing the firmware with all the base apk in one go.

Thanks

The easiest way to modify the system is to mount it in linux, copy the apps that you want, set the permissions, unmount
Update.img is not the same thing as system.img

We wait your upload with big interest, i am very curious what they did differently from we do, or other Devs are doing to charge money.

Hi & thanks for this work. I have a U23GT23C4 fresh from China, and have extracted the firmware using rkflashtool. We have (rkflashtool -p):

FIRMWARE_VER:4.1.1

As regards driver modules, partition "system" is an ext3 filesystem, and in lib/modules it has:

Not sure why it needs 2 of each, but there you go.

Hi Martin,

Thank you for that do you have, that will help massively, have you got dropbox if so i can share you a folder and if you could upload these files to it that would be great, i can then try and sort my tab out.

Thanks

Andy

userdata.img may contain personal data and it's not needed, neither is user.img. The rest is fine and I should be able to rebuild a working firmware with that. Let me know if you need access to our upload page.

Cheers.
