[EVO 4G General] cjh6386:
At least my conclusion is that it is broken. If at any point one of you thinks I did something wrong or there is something I can do to fix the issue, feel free to let me know.

I bought my evo sometime last year, I believe around September. I did not purchase sprint's TEP, I was content with the standard warranty and $35 repair fee if the time came. It only took me about two weeks to decide I wanted to root my phone, which I did successfully with unrevoked3. I removed bloatware with titanium backup, used setcpu, etc. and the phone worked great for a long time. I discovered rom manager soon after and tried some roms, including fresh, caulkins, cm6. I stuck with cm612 for a while and I loved it. I always cleared data before a new rom, and once I got used to the clockworkmod interface I used the cache/dalvik clear tools, as well as return the phone to factory specs feature.

Now, for as long as I remember, the phone rebooted itself unexpectedly, although it was very infrequent at first. Until about the beginning of Jan., it rebooted itself only a handful of times. It has progressed to the point where now I can't use it for more than 5 minutes without it rebooting. It will power cycle loop on the evo 4g POST screen, before android even loads. Sometimes, it will do this and stop power cycling, and simply vibrate 5 times and be unresponsive. The only way to stop this loop or the unresponsive state is the take the battery out and re-insert.

I troubleshooted as much as I could, before deciding that the issue was probably hardware related. Using the how to unroot your phone guide <http://xdaforums.com/showthread.php?t=780141> I unrooted the phone successfully (s-on), and loaded the original stock rom just fine. The phone still exhibited the same behavior with the stock software, so I took it to a store in Chicago a few days ago (I live in so. CA but was on vacation in Il). Anyway, I was foolish as I did not run the OTA updates to 3.7 and the tech lady told me it was happening because the phone wasn't updated. OK, my fault, even though that was a bs response.

I messed with it some more, it's still broken. So today I brought the phone to a sprint store here in CA, fully UNrooted, stock rom, updated all system updates. OTA 3.7xx, newest radios, pri, prl, profile. It is acting worse than it ever has before. I dropped the phone off and came back an hour later and the guy tells me that they reset the device and it should work now, and that I shouldn't root it as it voids my warranty. I said, how do you know it's been rooted? He replied with "our guys are really good."

So I took the phone to lunch right next door, fully stock again, and as I am logging into my google account to access the market it reboots itself again. And loops. I take it back to the sprint store and tell them look, its doing the same thing, you have completely reset it, it's not rooted, this is a problem.

Next they tell me they can't get me a replacement phone (for the $35 repair fee) because it has been rooted. I ask them to show me how they know it has been rooted, and he goes OK. He boots up my phone and one of their evos into recovery, and mine scans for the PC36IMG file and finds it. So ok, my bad again, but I say hold on a second. I took my SD card out and give the phone back. I ask them to prove to me that the phone is rooted, they try the same thing again and of course there is no difference between the phones in how they boot to recovery. Basically I press the issue further, the tech gives me some bull**** about how they can tell, if you root the phone EVER it leaves files on the phone forever. I can feel that they are lying to me, and they only know because I [foolishly] left my SD card in it as I dropped it off.

After spending about 30 minutes talking to their representatives and then about ten with the tech behind their repair center glass, he told me my only option is to talk to HTC to try and get a new phone. Mine has been red-flagged at sprint stores now for having been rooted, even though I NEVER GAVE THEM A ROOTED PHONE TO LOOK AT.

If you can't tell, i'm extremely frustrated, as my very expensive phone, on stock software and unrooted is completely useless.

Any opinions/ideas as to if 1) how I can get a replacement phone, or 2) what I have done wrong or what I can do to potentially remedy the phone?
