I found this site and have used and trialled the udgrades published there in. I have successfully upgraded to 2.3 and back to 2.2 and to the kgdtea beta version.
Yesterday I down loaded Mygica update 20111104.zip and update spi 20111102 from the Mygica siteas listed in a previous post.
Decided to write a simple "How to" for another site so I took my unit back to 2.2 with update_spi_all_2.2.zip. I then updated the Uboot and Recovery with update_spi20111028.zip.
I made an error and updated with the Mygica download update_spi20111102.zip instead of update_spi20111028_all_2.3.zip.
The update took and reboots but only with the section showing the warnings about turning off the unit or removing the SD card and there nothing else except an Upgrading message along the bottom. There is no sign that the SD card is or is not being read nor is there any error messages.
Whatever I try, reset button, pulling plug, turning of etc. it simply returns to this screen and stays there with no activity. Any suggestions?
BTW I found the pushing Ctrl/Alt/Del remote keys does a hot reboot.
1.Update SPI whichsupports degraded from 2.3 to 2.2, update_spi_all_2.2.img file, change the file name to update.img, copy to SD card and plug into thebox.
2.Go to setting->about device->update system to update.
3.After finished, update SPI for 2.2(0907 version), .
4.Copy the 2.2 SPI file to SD card, and change the name to update.img, press the button on the side of the box, andplug in power adapter at them same time, hold seconds, you will see updatefailed screen, then plug into SD card and use remote control to choose updateapply->SD card->update.img. after finished, it will go to updatefailed screen again,
5.download and change the firmware name to update.zip from the followinglink for android2.2, other 2.2 firmware version also is ok.
the same update steps as SPI. After finished, it will stop at upgradingscreen, press enter or ok button to choose the first option" reboot systemnow"
7.Go to setting->about device to check firmware version.
Uboot version is 20110906, recovery number is 20110907, build number is your firmware version.
If you want to upgrade to 2.3 again, just update 20111102 SPI and firmware again.
