Hey guys there is a new ROM release from Hyundai for the A7HD
The rom title (after translating) is Last Updated: A7 HD_ screen flash problem _ battery power & firmware upgrade package the _20120615
Updated: June 15, 2012
I Guess this update is for solving the screen flickering problem and the battery consumption
Did anyone try the update and test it.
I'm using now the Cyanogenmod 9 on my tablet
Can I flash this update using the Recovery?
I'm happy with Cyanogen but the battery drain is very high
lasts for less than 2 hours which is very bad
You can get the latest rom from here

Have anybody successfully flashed with this ROM.
My experience is like this:
Using the ROM upgrade guide and driver suite as suggested by IndigoHD in this forum, I tried to upgrade above ROM. It went smootly until the last step the indicator did not move even after waiting one hours. I suspect driver or the ROM img file problem? Has anybody succecfully upgraded above ROM?
So... what is the status of your tablet, now? And were you able to flash it back or recover?
The last official hyundai rom works fine and smooth, browser performance is faster than CM9.
Only google play is more restricted with apps.
I am waiting for better nightlies from cyanogen.

What about the battery drain, is it better than Cyanogen ?
I'm facing problems with cyanogen concerning power management as the battery drain is very fast (lasts for nearly 2 hrs)
also I'm getting same problem in both concerning 3G
suddenly while using the 3G usb dongle i get flickering screen then screen turns into colours then green then black and nothing is shown with no respond
i have to do a hard shutdown then.
Hope that both issues are solved.
tell me your opinion concerning both points please
My tablet is running with old 20120420 ROM. My Tablet is working no problem. Only could not flash with new ROM 20120613.
I have flashed the new official firmware and here is my experience in it
The Good in the Rom
1- The Rom is fast and stable I have installed many applications and it is showing very good performance
2- Battery life till now is better than previous versions. I have been using 3G for 45 mins and the battery drained 12% only which is much more better than before
3- Screen flickering problem has disappeared so now i can increase the brightness to maximum level and enjoy
4- 3D games are running and performing well
5- Browsing speed is very good. I haven't tested the Wifi till now to see the strength and speed but as soon as I test i will post.
6- Errors that used to appear after installing some applications have gone and no errors appeared to me till now
The Bad in the Rom
1- The market is not the full market, still i'm getting incompatibility issues with some applications
2- Still facing same problem with 3G modem, my modem is Huawei K3565 with vodafone line, the modem is working well but sometimes without any alarm the screen flickers and turns into colours then my tablets hangs and stops responding, i have to do hard shutdown then.
3- The internal storage is now reduced into 500mb and the SD is 7.5 GB, i actually don't know why this happened or how to make the internal 1GB and rest as SD
4- My old cyanogen rom used to have more display options and bluetooth which are not available in the stock rom, so I wish to have the option to add bluetooth support to be able to plug external bluetooth.
Still testing and will post more as soon as I go deeper.
I really recommend this Rom as a start
If someone could fix the market issue on the new ROM I'd say it's nearly perfect.
In live suit it looks like the update is completed but the tablet would not reboot and is not working.
