Help phone problem display 3d

[chrcol]

Ok I noticed a problem with my phone and its hard to say when this problem started.

Summary of the problem below.

If I load an app that uses a high resolution (I think) and possibly also 3d graphics. It will briefly work and then appear to hang. At this point only the home button works, nothing else responds.

If I then reload that or any other app which uses a 3d display I then only get a blank screen with only the home button working.

Apps so far with problem.

Gallery
Gallery 3d
The game of life - game

Also "Quadrant Standard" has the problem but doesnt crash.

Quadrant standard if I run the benchmarks without loading any of the above 3 apps it will complete normally. If I load one of the above apps, and then have to use home to get functionality back and then run quadrant standard, on the 3d tests I see the fps score during the test but no graphics, it still gives a score at the end.

I first noticed the problem on game of life so I dont know if thats overwritten a graphics driver or something. But its possible the problem already existed as I havent used gallery since the first day I got my phone and not ran the benchmark for many days also.

When the apps briefly work after a reboot its extremely briefly, they work for under a second.

ok an update.

every reboot makes the app temporary work again.

its more than a solitary second now.

I booted the phone.

loaded gallery 3d.

then started clicking on aphoto, then back again then photo again, repeating. 5th time the app froze. At this point every repeat load of any gallery app or a 3d app yields a blank screen until reboot.

it doesnt seem to be any specific photo as the photo that crashed before then worked fine right after a reboot.

There is 15 pictures but only 7 files in my dkim folder, so dont know where the other 8 are installed.

ok another update for the curious.

I wiped my cache in CWM on the recovery menu.

On reboot all sms, settings were gone although apps and contacts were intact.

Also I had extra apps crashing such as DWM and titanium backup. Since titanium backup wouldnt run I couldnt use any of its backups. I went back into CWM and restored a backup I made 12 days ago which now has the phone stable including gallery.

Incidently game of life doesnt crash now either but that says not supported on my device (more on that in another thread).

So my phone works again now and so isnt a hardware issue.

ok an exact explanation now.

I had cf-root installed b82-ex

I skipped the fix patch for it as I did it wrong at the time and noticed no issues.

However the fix patch fixes this exact problem which is crashes in gallery and 3d apps stop displaying as well as a couple of other bugs.

So it was a cf-root kernel bug which I have now fixed with the patch properly (had to patch in CWM manager not recovery mode).

Not sure about when the phone went crazy after clearing the cache tho, I wont be using that function again without a backup right before it.
