Hello, sorry for writing english only im from Germany so i dont know russian language (use google translator ^^)
I want to say thank you for providing the Firmware.
I have the same Situation like Swetch.
One GV7777 could use firmware pgps7777cis_v10.0.1_4.0.4_iml74k and now have android 4.0.4 (with everything working),
the other "Can" use firmware pgps7777cis_v10.0.1_4.0.4_iml74k to but without working camera and dvb-t and bluetooth.
If flashing pgps7777ru_v5.0.1_5.0.3_iml74k everything is working but only Android 4.0.3 and no update to 4.0.4 (only bugfix pgps7777ru_v5.0.2_4.0.3_iml74 witch correct some playstore errors).
Is it possible that some User can check why bt, camera and dvb-t working in one firmware and what it need to make it work with pgps7777ru_v5.0.1_5.0.3_iml74k ? Only thing i can see is that NAND is formated different.
Please dont hit me for asking but i want to try to get latest 4.0.4 (have a bug where Wifi Symbol show only one "1" bar but have perfect connection

)
