The wifi icon stays lit, indicating I am still connected to the network, but I have no connectivity on any apps. If I'm in the middle of an update, for example, it just stops, and it won't resume.
I can reset this problem by turning wifi on and off, but the exact same problem arises within a minute. Interestingly, the wifi at a nearby starbucks seemed to be working fine - but both of the networks I am having issues with ran very well on stock android. I don't know what is causing this problem but it is rather troublesome. Any suggestions on how to fix this?
While I'm at it, when I update to the newest CM7 nightly build, do I need to do a complete wipe or can I simply install it on top of the current build? Thank you very much!
I'd just update. I didn't have any problems with wifi on the 05\06 build of CM7.
Unless you really need flash and camera, the latest CM9 runs great. The camera sometimes crashes randomly, a reboot fixes. I've used it as my primary rom up until last night actually and highly recommend it.
As far as wiping data and updating is concerned, I've always wiped data in-between rom installs, well, always since the second or third rom flash where I didn't and bad things occured. The problem is that newer system apps still have old data that can be incompatible with the updated system apps. You can try, but it'll probably be glitchy.
What you can do to back up your user apps (not the user data, passwords, etc) by using the following adb commands; Linux users change "C:\app\" to "~/app/" without the apostrophes "".
- adb pull /data/app/ C:\app\
- Then enable adb in the boot, before first boot.
- adb remount
- adb push C:\app\ /data/app/
- adb shell chmod -R 0644 /data/app/
You can also save the apps to your sdcard instead of your computer by changing "pull" to "cp" and "C:\app" to "/mnt/sdcard/app" for both commands. This is the method I do to back up apps in between flashes (to my pc). I lose configuration data, but that's also where the glitches come from.
You can also back up app data by pulling /data/data/, but its not recommend since you need to also delete all system app data from that pull -- system app data & dalvik cache & system cache are the main reasons you need to wipe data between flashes.
The biggest problem we face is that user installed apps and system installed apps share the same folder for storing data. Where it should be something like /data/data/user/ for user apps and /data/data/system/ for system apps, instead its all clusterf**ked into /data/data/. Hope this helps.
@ccdsatt -- not since I ran stock Froyo. Although I had a similar issue running wifi and streaming pandora, playing snes roms, using a ps3 contorller over bt, overclocked to 1200mhz, on an older Defy CM7 Epsy port, all at the same time. Battery still drained even though I was plugged into the charger.
Found out that the Bravo doesn't like everything running that can be all at once, but it did run smooth...
