Quote:I had a normally working firmware in my Mygica ATV1200 box - Android 4.1 Geniatech Firmware 20130805. Then i wanted to test other firmwares and downgrade my box to this version (http://www.geniatech.com/news/mx-atv...nstruction.asp). I installed this SPI (http://www.geniatech.com/down-eng/an...0120917SPI.zip), box rebooted and thats it... i only had a red light and no chance to get into recovery.
I tried rescue my box with those firmwares:
http://www.mygica.es/downloads/Manua...1_20130805.rar
http://www.mygica.ca/forum/download/file.php?id=71
Nothing worked (i think its because my box SPI was broken and there was no way how to get into recovery)
I downloaded this file (http://www.sendspace.com/file/kr3wta) and created a boot card (steps 1-4 feom instruction). In Windows 8.1 i opened SDcardMaker.exe as administrator otherwise i cant see my sd card
Downloaded the files from below link and done everything from readme (http://www.sendspace.com/file/qdkl2y). Tried to boot my box with this card in and holding the recovery button - no results. Then tried to boot with recovery button and pin bridging (http://i.imgur.com/3WEhxnZ.jpg?1) - boot started but after upgrade the same red light.
To sucessfully recover my box i changed this:
Downloaded this spi from Finless Bob (https://docs.google.com/file/d/0B9BF...1ab3NhUkE/edit) and copied it to my rescue sd card.
In rescue SD card opened file factory_update_param.aml (with notepad) and changed this command (--update_package=/sdcard/update_stvmx_20130805_eng.zip) to this command (--update_package=/sdcard/atv1200_spi_assertion_removed.zip)
With SD card in the box bridged those 2 pins (http://i.imgur.com/3WEhxnZ.jpg?1), holded the upgrade button and plugged in power adapter. Waited till SPI update ended and after that my box rebooted automatically - sucessfully rebooted into Android that i previously installed on my box (Geniatech Firmware 20130805).
I dont know if this method will work with other ATV1200 boxes which are bricked other way. If somebody want to try this method - try at your own risk Im only sharing my unbrick experience
