[Q] Random Crashes

Anyone noticing random crashes with the g2 cm7? Atleast once a week when I take it out of my pocket it doesn't power on and requires a battery pull to turn it on. (No lights, nothing)
Battery voltage issue?

Different people have been having different issues. What nightly/RC are you on? did you do a full data/cache/dalvik wipe before flashing the ROM? did you try fixing permissions?

Yup, I know there are some issues but it seems strange that the whole phone goes into a stale state which requires a battery pull. I believe its happened once or twice with cm6 as well.
I have done all the wipes and fixes etc. I am right now on nightly #15, I previously was on nightly #7 for a long time so maybe it was just that release. Thanks for your reply.

Haven't had one random reboot. Still using nightly 6. My mytouch4g has not had this problem either.

Are you overclocked?

Only to 1Ghz.

Today it died while charging, dead and needed a battery pull. Any ideas?

You're not the only one with this issue (myself included), and the cause is not yet known. And it seems there may be a couple different variations of this issue with the same symptom (of the phone powering off while asleep and needing a battery pull to power back on). May be related to overclock, GPS, screen-off profiles, full moon, or who knows what. See this thread for some various thoughts on the problem.

I personally think its a kernel issue, or that the kernel is at least one of the factors. I flashed pershoot's kernel and the problem seems to be solved, so far (keeping my fingers crossed). Having the GPS on while you turn of the screen also seems to be a common trigger for many who experience this problem.

Hi there,
Thank you so much for your reply! I couldn't seem to find any information on the forum.

I just wrote a post because I had the same thing happen to me. Phone just went dead for ni reason and I had to pull out the battery. But my phone isn't rooted. So it might not be because of CM7.
Tried to call Bell, but the wait time was too long. So will try to call them when I get home.

There are at least two other threads about this on XDA and quite a few others on the net.
Google HTC phone freeze random crash reboot battery pull or some combo.
No solutions and it happens on stock phones as well as rooted.
Did you search?

Having the same problem recently on my unlocked Desire Z from Bell, using on the Rogers network. It started yesterday and all of a sudden it turns off, and the only way to turn it on is removing the battery and putting it back in. This never was an issue for months. The only thing I updated from that affects the hardware is the new Google Maps, so I think GPS may be the case. But I really need GPS on my phone...

Yesterday I did an experiment with GPS. For me GPS is the case that makes my phone to freeze. With new Google maps it freezes even faster, more often.

[Q] Random Reboots

Ok guys, I know that there are posts about random reboots but it seems non have a solid solution. My Hd2 has started doing these annoying reboots for about a week. I was using Tyweens NexusHD2 2.9 and all of a sudden reboots started. So I switched to Typhoon CM7 3.5.7(currently on phone now). Reboots still occur. So I did Task 29, wiped sd card, plus clean install of Typhoon CM7 3.5.7. Phone still reboots. It actually rebooted during setup. I even changed from Magldr 150/5(suggested) to 200/45 thinking it was memory related. Still rebooting. I have noticed it does it more when WiFi is on. Is there something with the latest Android 2.3.5 and Wifi? Any help would be greatly appreciated.

No not at all.

I'm having the exact same problem... but strangely now even when I try older gingerbread builds, it does the same thing. Its only been recently, too... I've had the phone for a while and I don't remember it doing this.
I can have the, same build and same gps libs on my wifes hd2, and hers won't reboot. Mine will.
I even went as far as swapping out my mainboard with another one I had from a cracked screen issue... and that didn't solve the reboots.
I can't figure it out. It must be gingerbread and certain phones. Ive tried 2.3.5, 2.3.4 and 2.3.3 and they all are now rebooting. I don't know why its only been lately, too. The, only thing that solves it for me is running Tytungs NexusHD2 ROM v1.9 Froyo based. I can even add the latest agps fix and don't have any reboots. Only thing I really miss from gingerbread is the DSP bass boost which makes a huge difference for my bluetooth audio via my car.
Remains a frustrating mystery to me.

I always set this as my default wifi policy since I am always connected at home. So that's a no-go for that tip. At least for me, personally... still reboots.

So far the only thing that works at home is to turn off 3g.
I am trying Rafdroid 4.2 and so far has not rebooted away from home.

Rafdroid is a Froyo based ROM - same with the NexusHD2 v1.9g build that I'm using and so far no problems.
But when using any gingerbread (sense or non-sense) / CM7 build, I am getting those random reboots. Sometimes so much to the point where the phone is unusable. Then there are times when I could go hours without any. I thought it was something related to 2.3.5 since that's right around the time things started going strange, but like I noted - I've downgraded to 2.3.4 and 2.3.3 - and the same thing is happening. I used to use Hyperdroid GBX 7 for months without issue... now when I load it, it gives the same result. Same with Hyperdroid GBX v12, Hyperdroid CM7, Typhoon, stock bravo based CM7 Nightlies, AmericanAndroid, NexusHD2 Gingerbread version or anything Gingerbread based - period.
It also seems coincidental that the reboots started right around the time when Tmobile issued a bulletin asking for user input about recent unusual high battery draining with mobile data. I really haven't followed up and I don't know if it was determined what was causing it for some users but I am thinking maybe it could be possibly related. I can't explain why my wife's phone can run the exact same ROM and not experience the same thing yet mine does. It seems like an isolated issue - I don't see a lot of people complaining about the same issue lately. Maybe it has something to do with a specific mainboard revision/manufacturing date and some kind of over sensitivity to mobile data power output or something. As I noted in the prior post, I did switch out the mainboard with another one that I had laying around. I did take note of the revision manufacturing date stamped on the board, and they were identical. And both experience the identical problem. My wife's HD2 was bought 3rd party from a private owner at another time separate from when the 2 HD2's I have on hand were purchased. Perhaps she has a different revision/manufacturing date.
The two mainboards that I am having a problem with have a date of 2010/03/16 - they are both identical.
I would take apart my wife's to check her date and am willing to bet it's something different, but I've had really bad luck picking apart these HD2's the few times that I've done it. I've broken wifi coaxial cables and ripped flex cables. The date is stamped on the bottom of the mainboard.

Same behavior here - had random reboots multiple times per day until I switched to 2G only (only adjustment I made)....have not had one in over 72 hours of uptime now.

OK, I can now pretty much confirm my original hypothesis about the mainboard. I have switched it out with one that was manufactured in late 2009 according to the timestamp on the board, and that's eliminated this problem for a while now with Gingerbread entirely.
The exact problem is beyond me, but unfortunately I stick to my guns that it's a hardware issue. Not sure why it would affect Gingerbread so much more than Froyo but my guess would be it has something to so with mobile data power management or something of the sort.
So for those saying that turning 3G off counteracts this rebooting effect, try a good Froyo build to keep your 3G connectivity. The reboots didn't happen nearly as much as they did wile running Gingerbread for me (although I would get 1 or 2 every few days).
Unless you can get your hands on another mainboard... or another phone.
Replacing my HD2 entirely for now wasn't an option for me... it's the only "Android" phone that I can run with the grandfathered 5.99 Tmobile web. Any native Android phone is identified by tmobile from its IEMI and forced to upgrade to a smartphone data plan to work with mobile data. They just happen to allow legacy (less than WP7) Windows Phones work with that old data plan, which is what the HD2 is.

+1 switching to 2g sucks but works,my wifes hd2 works fine though like others have mentioned. this is crazy lol
BTW all these reboots stated for me when to mobile messed up their signals and was causing android phones to have high batt drain.

Where can i switched off 3G beacause i've the same problem with reboots?

Settings networks and mobile network

I have notice mine does it when I am at home using WIFI and 3G is on. If I turn 3G off all is ok. When I am out and about I can turn WIFI off and 3G on and no problems. Wacky.

i had a similar problem on my hd2 tmobile with coredroid 1.6 on it..
Random reboots have become all too often, usually when i start applications and i did not want to waste any more time so I changed the rom...

I would get a random reboot every two our there hours until I took of all my widgets except for two and I haven't had a random reboot in about 2 days and I didn't mess with the 3g signals. but my phone still has battery drain issues

No, I couldn't get the zip for 4.91 to flash for some reason so I did Neutrino 2.5 after sever data formats.
update: on on GB 4.5, same problem persists
SOLVED

How did you solve the issue?

I'm having the same issue too. It's only in regular cell calls. The phone becomes unresponsive to everything, screen wont turn back on, etc. Battery pull is the only thing that has solved it for me. It's happened three/four times in the last month, at least. I'm running CM7 Faux 1.1, back when it was originally released. This isn't just a CM9 issue.

Well the issue was less solved but minimized in the end.
After many fastboot formats and CWM flashes, I ended up fruitcaking back to 2.3.4, that's when the problem started to be less of a hassle; meaning the screen would come back on and buttons/soft-keys were again responsive and a battery pull wasn't needed.
I re-installed Turls ICS and the problem is still present, but it doesn't hinder making or receiving calls, I just hold my breath with each.
I'm suspecting that when flashing either the kernels or roms, things are not getting cleaned and formatted as well as they ought to be. I know there is a universal CWM zip floating around somewhere (seen it in the skyrocket forum). We've had similar issues in the skyrocket forum where remnants of previous flashes were being persistent, or resistant to format attempts.
I messed with it for hours trying to fix so I cannot say for sure what I did to make it a non-immediate issue, but if others describe like problems I try and help.

I was having the issue with Neutrino 2.1, 2.5; Turl ICS, and stock 2.3.4. The latter seemed to be the most effective method I employed to fix, without bricking.

Lock On Sleep

Hey folks,
My wife's MyTouch 4G has suddenly started locking once it goes to sleep. I cannot wake it up at all without popping the battery
here's what I've tried
- Removing potential problem apps
- Hard Reset
- Clearing all items in recovery (cache, delvik(sp?), battery stats, etc..)
- SIM swap with my phone (also a MyTouch 4g)
The only thing I didn't do was try a different ROM, only because her and I are using the same phone, and my install is working perfectly fine (Awesome ICS 3.6). Any other suggestions before I look at getting a new phone?
Thanks!

Personally I like Frosted Cherry There are a few more here in Awesomes OP HERE though. If one doesnt seem to work give the others a shot.

Well, sadly I did a restore on her phone, and now it just locks up on boot and never gets to the setup process for your account. Then I tried another rom and it complained about an unexpected offset (different numbers each time). Then I found this post.. http://forum.xda-developers.com/showthread.php?t=1394238
Followed the instructions to restore to the factory OS... now it doesnt get past the boot animation, or goes to sleep during it which requires a battery pop. What the guy explained in the post about the eMMC chip going bad exactly describes the behavior of her phone, so I am thinking it is that. We ordered her a Samsung Galaxy S III ($600) last night after spending about 4 hrs trying to get the phone to even boot to the OS.
Sadly I think its toasted
thanks for all the help/suggestions though, I may use them on my phone since mine is still alive and kicking with no issues (*knock on wood*)

Hopefully the samsung works well for you. Personally i've never heard of a "Bad Chip" phone acting that way in particular. When you boot into HBoot (Power and Vol Up at the same time) do you still have S=Off?????

[Q] Can reboots be caused by location?

I'm have troubles with my HD2 randomly rebooting itself for apparently no reason. Initially I had a barebone CM7 ROM, and it seemed to reboot much more frequently when I came home from university. As soon as I got home for this break, sure enough, it began rebooting again. I then switched to a CM10 ROM, thinking it was just the previous ROM messing up, yet the problem persisted.
If it's not a ROM causing it, what could it be? It's really annoying having the phone shut off randomly while I'm doing something, and I'm worried it'll end up worse just because of how frequently it reboots.

overheating? failing touch screen? dodgy battery? failing hardware? faulty/fake copy SD card? old/wearing out sim card? some app that doesnt play nice on the hd2?
they can all cause reboots on multiple roms, along with another half a dozen reasons, i'm sure.

If the phone did reboot from any of those, it still wouldn't explain why it doesn't happen when I'm at school. I'm not exaggerating; once I go back (about ~126 miles away from home), it never reboots like this. At this point, you may be thinking, "Why not just wait to go back?" I have only two semesters left, and I want to get this fixed prior to me moving back here.
But nonetheless:
overheating?

I've held my phone in front of an AC to test if it's overheating, and it still rebooted. I had the back cover off and the air blowing into the battery.
failing touch screen?

I thought this was the case at first as well, but I uninstalled all my apps on the barebone CM7 ROM, and reboots still occurred. Even after doing a fresh install of this CM10 ROM, the phone rebooted before I even began installing apps to it.
Are there any files that don't get changed by flashing a new ROM? I was thinking that it could possibly be the modem I have flashed to my phone, but I wasn't sure if flashing a new ROM automatically changes the modem as well. Can I get some insight on this?

By modem do you mean the radio? It's unlikely to be the radio itself, however it could be something like the phone struggling to switch between 2g and 3g,,try it with the phone in only 2g mode,, perhaps you have a faulty cell tower in your area,,unlikely but not unknown.

Yeah, sorry about the terminology haha. But thank you, I'll try that and report back!

So disabling the 3G didn't change anything, but I noticed a drop in the frequency of reboots when I disable my wifi. Could some of my router settings be messing with the phone? I tried deleting the network on the phone and re-adding it, but the reboots remained consistent.

still sounds like hardware really, as suggested.
does it reboot even with the phone in airplane mode?

But the phone doesn't reboot when I'm in the city where my university is located, only when I come back home. That doesn't really lead me to believe that it's the hardware.

I have the same problem with the
[1.Dec.2012][All in One] EvoHD2v10 ICS 4.0.4-full HWA "Fastest ICS ever"
it reboots more than 3x a week!!!!!!!

For me, it can literally get up to 10 reboots per day, when I'm in this particular city. It gets very aggravating, and I'm worried about the stress it's putting on the hardware by constantly booting back up.
Anyway, I decided to say **** it and start from scratch. I don't think it's a hardware problem, so I decided to go back to the beginning. I formatted and re-partitioned my SD card for Native SD-compatibility. I flashed Xylo's 4.1.2 PA ROM. Now it's time to use it like I would normally.
If anyone is experiencing the same problem as me, or reads this in the future with the same issue, I'll try to keep the post up-to-date with what stopped the reboots for me.

dont forget to clear out your sd card, , leftovers from previous roms can cause issues. Easiest way is to flash teh new rom, then immediately in CWM do a wipe data/factory reset, as this clears out both fat32 and ext folders.

AW: [Q] Can reboots be caused by location?
I had the same problem with my fathers HD2. I installed clK before and it rebooted the last time quite often.
So I reinstalled everything. I started installing the official HTC WinMo 6.5 Rom.
Then I've done Task29 and installed MagLdr and then a Radio which Supports 576 MB Ram. (I think it was 2.15.xx) , repartitioned it for BlueOrange Mix Rom 1.2 (The best I ever installed so far) and flashed it in CWM.
So the HD2 is running since 150 Hours without any Problems.
P.S.: Task29, MagLdr, Radio Installation and Repartition has been done in HD2 All in one Toolkit.
Greetings by Myself5 and I hope I could help you.
