Hum.... Just a weekly update?
I think I will wait for Android 3.0 kernel and back to Gingerbread 0217 until then.

Well to be honest I am happy with the speed of solving problems at the moment, though I wonder when they are going to include the 900MHz kernel that is running smoothly for all of us.

Eventually if the market app updates are getting fixed (Adobe Flash & Google Maps) then there are no downsides for me anymore.

After running Gingerbread on phones I definately see the full potential of ICS on tablets (never want to try GB on tablets anymore, Honeycomb atleast)

Can anyone say what version of flash player is supported in this ROM?

Can we include the 900 MHz kernel when flashing this ROM?

Still no word on the Gtalk issue. (Had camera option that crashed the program, now camera option doesnt show anymore)

Love Skype, but it´s not the only program used for video chats.

yes, tried but seems to be lazy as the last one (0306)?!?!?! flash support isn't good (browser is restarting) and so on... go back to 0306 with 900mhz kernel.

yes, flashed and it seems to have no real issue for me. did not use flash that often. gtalk issue for me is that there is a overlapping statuswindows, but i can see my conatcs online etc. was suprised about new bootloader screen, spotify is working so my "touch radio" is ready again.

but old kernel, 2.6.xx no 3 but atp told us that this is huge work, so we have to wait. maybe i will try your 900 kernel fix this evening

yes, I flashed it, and everything is looking good, to this point. I haven't tested a lot yet, I just got it loaded up. Videos seem to work pretty well (mp4's) will let you know as soon as I test out others. -Tom

There's nothing in this update that I need so I'm waiting for the next big update e.g. kernel v3.

Who can tell me:

1. Does the built-in VideoPlayer play movies in FULL-screen without any status bar, etc.??

2. Despite official claims, does the built-in VideoPlayer play AC3 auduo?

Thanks!

Well, that was quick - that last kernel lasted what? 6 DAYS??? sheesh.
LOL, looking at the Zenithink Download page I thought there was already another newer ROM out, the 0314, but I think they just renamed the 0312 as I think the download file is still the same.....

1. Yes it does, you may still have black at the top and bottom, but this depends on the resolution of the video, if you go into settings and select full screen, it will stretch the picture to hide the black lines but it then looks out of proportion.

2. Not sure, how can I check if the audio of a film is AC3?
edit: I went to properties, then summary and it says Audio is AC3 and it is working fine, I had not tried this film before, so I don't know that it didn't work before this update.

upgrade, thank you very much! Good news!
So, there's only one thing that still remains unsolveed for me. That is Volume+ (Sound Boost) not working properly in ICS (I just cannot imagine listening to music without it).

Still unable to update Google Maps with this firmware.

Google Play says "Error - Package file was not signed correctly. Uninstall the previous copy of the app and try again"

Could other users please confirm?

Hi,

The download page says: 10" C91 (512MB+8GB) android4.0 2012-03-14_2n_3n_3a as already mentioned.
The download link is ,,,/ZT280_H1_2n_3n_3a_C91_Android4.0_0312.rar
BUT if you modify the link address manually to ,,,/ZT280_H1_2n_3n_3a_C91_Android4.0_0314.rar

Your get the 2012-03-12 version.
No idea what the actual difference is, but files are definitely different.

Just downloading now. will flash later.

Cheers
