random vibrating with CM7? - EVO 4G Q&A, Help & Troubleshooting

Flashed CM 7.2 on a friend's Evo 4G and as far as I know it was working just fine, but it has started randomly vibrating every 5 minutes or so, even when it's turned off. Any suggestions as to what might be causing it?
Yes, I am very sure I thoroughly wiped it before installing. And there don't to be any persistent notifications.

[Q] 4g tries to turn on and then immediately turns off?

It seems like after I installed MYNs twopointtwo RLS-2, 4g stopped working. I can click on Turn 4g on, and it acts like it is starting up but after ~20 seconds it turns itself off before getting an ip or anything like that. Any ideas/fixes?
Sorry if this is already posted, I couldn't find it...
This same thing is happening to me as well. Did you ever resolve it?

Repeating Splash?

Now, it's not a bootloop. Thought I'd clear that up first.
Sometimes when I reboot my phone, it'll loop the splash maybe 2, 3 or even more times and then get to the CM7 image and start up.
I noticed this after activating Wifi. I don't know if it's the cause, though. I'm actually gonna test that after this post... Just wondering if anyone else is experiencing this.
Started on CM7 RC...4, I think. Still doing it on Final as well.
Also, my Wifi stopped working. D: It was working the first time I turned it on, rebooted and then it was borked.

Suddenly my mt3gs starts to vibrate and reboot

This problem it's becoming more and more frequent - it was once a month, then once a week - now almost daily
The mt3gs starts to vibrate very fast for 5 seconds, black screen with no interaction possibility, and then reboots.
Ever happened to anyone?

Cant say Ive had the exact same issue, but have had similar. Could be a number of things. Some ROMs have problems with phones rebooting when WiFi is turned on. Not sure about CM7 though. I would recommend making a nandroid backup, and reflash your ROM. If it stops happening, it is likely an app or something corrupted causing it. If it continues, go back to a stock ROM and see how it acts. If it stops now, then it was probably something wrong with the ROM. If it continues, it may be a hardware problem that cant really be fixed. (try a different SD card too.)
Yes, sometimes when i turn on wifi, the phone reboots, but it is a different behaviour - the "wifi reboot" it's a system crash, so the screen suddenly turns in the mt3gs boot logo.
When this happen, it is starts to vibrate a lot (for example, it happened at 4am, it woke me up, even if it was far from my ear), then "dies" for a few seconds (doesn't respond to any button press), and then reboots
very strange...

Phone goes to sleep instantly after waking up

This morning, I experienced something strange on my Hercules. The phone display automatically turned off after waking it up within a sec, it happened on and on. Sometimes it would last for 15-20secs then turn back off. Sometimes (very rarely though) it would power up fine and stay that w My timeout setting is 1 min, so it was not because it was timing out. This happened all throughout the morning, then it fixed itself miraculously after 2-3 hours.
I'm running the official CM9 RC2 rom. I don't think it was a software issue as luckily I had nandroid backup from 2 days back which I was able to restore, yet the issue was still there. What do you guys think? My guess is the power button was acting screwy, maybe it was not releasing properly or something.
The answer lies within the depths of your soul. When it is destroyed, only then will you find your path.

Something similar happened to me on aokp milestone 6 with the original kernel.. The screen went off and whenever I tried to turn it on it would back off again almost instantly.. Not giving me enough time even to do anything on the screen.. It kept doing it till I did a battery pull... Haven't experienced that since

[Q] D855 shuts itself down when I receive call. Why?

Hi! My phone keeps shutting itself down when I receive calls. Well not all the time but, it happens a lot lately. It just rings for a second and shut itself down, when I turn it on, there is nothing in call log. No way to tell who called, very annoying.
It started to happen on CM-based roms. Resurrection Remix and Darkobas, that's why I went back to stock. There was no problem for days (when it happened, it happened everyday at least once) but for the last couple of days, it started to happen again.
Does anyone have this problem? Any solutions?
