[EVO 4G Android Development] DroidGnome:
Thanks but I just verified that I do NOT have the A2SD version.

Just to clarify here's what I've done so far with my newest 'test' , that can duplicate the issue.

1) Wiped phone back to base rom. Cleared Cache and Dalvik both before and after the wipe. Setup my my gmail account in phone, nothing else.

2) Installed Titanium backup from market. Installed USER Apps (No system apps).

From that point on large apps fail to install. Furthermore I've been able to remove a few apps and those very same failed apps, work fine.. but of course the ones I remove won't go back.

I've since wiped my SD card and used default Froyo to move everything to SD.. phone is showing 219megs free. Still the same issue.

I'm somewhat at a dead end, as I've tested everything I can think of other than flashing a previous version of the ROM or trying a new one.... Going to try the built in phone wipe rather than recovery to see if that makes any difference.. but I'm starting to get annoyed at the lack of support with the Android market. At least if it gave me some sort of error I would know where to start. At this rate I'm going to be forced to pirate software just to install it ;(

UPDATE:

Ok I THINK I have figured out what is going on. Just so I was clear, I went and Wiped the phone entirely , reflashed ROM version I.2a with root explorer, wiped the phone AGAIN after flashing the rom, just to be sure. Each wipe consisted of Data, Cache and Dalvik-cache each time.

Now, then I decided to abandon my titanium backups in case there was something there.. I used the Market only, and reinstalled all my purchased apps, and a TON of freebie apps i could find (some I had never had before).. every 20 or so checking to see if a large app would fail . I used Angry Birds (reg and seasons) and Firefox as my test apps. Each time I tested, I'd try all 3 apps... they all 3 either started to download, or all 3 failed. *except near the end, see below*.

As I installed another 10-20 apps I'd keep checking those 3, noting also my phone's reported storage space. Around the time the phone reported approx 164-174megs free, is when everything starts to break down.

At 164megs free.. Angry Birds fails to install. Firefox starts downloading, but once complete, simply stops (assuming the install failed since I see no app).

At 174 megs free, all 3 apps download just fine (though I do not give them enough time to install, my concern is that they weren't even attempting it).

Somewhere between those two numbers things fail, depending on the size of the app I'm trying to install.

Now here's where I think I might have the answer.. I remembered that this version of the ROM, Steel did something different. His notes said "Dalvik moved to /cache ", and I recall when I upgraded my ROM before from Version H to I, I gained... 160megs!!

I believe now that the Android Market is still counting that Dalvik when it computes how much free space the phone has. Note, the phone doesn't calculate that.. but I think the Market does.

Now to test this, I just need a little feedback from any other app-whores like me out there :D

Does anyone have LESS than 160megs free, Running ROM version I.1 (either flavor)? If so, and you do not already have either of the following:

Angry Birds

Angry Birds Seasons

Firefox Browser Beta

Could you attempt to install them from the market and report back.2
