[Galaxy Tab  Android Development] russel51:
i try to resume all (many of it can be included to the main post about the cm7 port on gt7 to prevent a lot of questions contained in the 200+ pages).

i was coming from latest firmware EURO release of android for gt7 2.3.3 on samfirmware (JQM) with CF-ROOT kernel 3.3 and CWM (3.2? - not important).

i tried first to flash via recovery the .zip, no luck, freeze on boot animation (samsung galaxy tab); as said in the topic even if freezed new cwm is however installed.

i've tried a couple of times to flash with the new recovery with no luck (same issue).

so let's go with heimdall (first option, no repartition - the benefit of flash with repartition is not really cleared to me as i read in the post, can you explain it?)

all good, cyano boot, i've done the 2 wipes and a software reset from the android options, followed the wizard and get my system back fully funcional with clean cm7.

as said in the topic with heimdall version i have market already installed, tried all the options to install all the programs i need and the only one working correctly is the oldmarket.apk found here on xda.

other gapps didn't install from recovery (many tries, many wipes )

so now i have all like my old official 2.3.3 but very, very, very, very, very faster and with best dpi. good work and thanks to all the team made it possible.

so, here is what is not going ok:

1) video playback - i can see all my old videos and divx in the icon preview in file manager and in the gallery. when i try to open it, audio goes ok, but video is full green (same green of initial "audience" page of movie trailers).

the same thing happens to any other video i try to play: youtube app, browser,...

this thing happens on 1 reboot on 3, the other 2 times all is ok.

2) video recording - video recording is possible, using videocam illusion app setted to 800x600 capture resolution. video is not the best of the best, but it's working. videos are in the folder "videocamillusion", mov format.

even with lgcamera you can set the options to capture a movie (with better quality than videocam illusion), but the app fail to stop the recording and crash.

if can be helpful or someone is interested this is the data of an original video file made with tab 2.3.3 from samsung:

3) GPS: using sygic (11.2.0). with the stock rom the gps fix was almost instantaneous (10-15 seconds). now i can get a good gps signal only after 5-7 minutes, before that there are 5-6-7 satellites locked, but with poor signal.

maybe you can add even a short line to the first topic, sort of:

"download heimdall for your platform, extract it, place in the same folder the extracted heimdall rom, navigate with cmd to the heimdall folder and run the command:..."

this will prevent many questions and will save a lot of time to the first time heimdall's users.

so, thanks for your work, for your help and for your patience, i hope to help the development of this beautiful rom giving feedback.
