Urgent Help: HTC P3600 Freeze!

Hello,
I am owner of HTC P3600 from last 12 months and i used custom roms too all was working fine and before 2 days i found that whenever i leave the HTC for few hours it hangs and when i press the standby button to wake it up nothing appears on the screen and i have to reset it to start it again.
Updates:
Ok i re flash the Hard SPL, Radio and Rom and until now (in last 24 hours) it don't hangs.....
Update 2: I think the battery is the problem as the battery time is decreased from 3 days to just 1 and a half day and it freeze now while charging....
Any solution? anyone experience the same problem?

Help please with your views...............

I have a similar problem. My HTC started crashing after a rom update. However, i think it is not crashing due to software...
Well, the software is more CPU demanding, so it heats more than before. Also, i started using backlight properties set to high (i need to set to low again), which again highly heats the PDA. Finally, when charging the battery tends to get very hot. All this put together causes the CPU to overheat and crashing.
At least, from my experience, when it crashes it is always very hot.

Sounds like a radio rom problem. Try to reflash radio.

Thanks for the advice!
I will reflash the radio rom.
If it solves the problem i will update my post here so everyone else knows how to solve this kind of problem.

it helped ? reflashing the radio rom ?

lol you ****up your phone hahahahahahahha

No, it did not helped. Probably it is an hardware problem.
The pda was intensively used connected to the computer, because it was used for software developing.
I think it is broken, hehe.

[Q] Freeze and reboot

Hello everbody,
bought 2 weeks ago the Nexus 4 16GB and I'm very happy with it.
But i have the problem, that the device restarts when it is under load, means i play or watch something what needs
the full power of the CPU and GPU.
It happens a lot when i play Iron Man 3 The Official Game or Dead Trigger.
Than the device freezes, can't kill the app or even lock the screen and after 10~ seconds it reboots itself.
Active Wifi, Bluetooth, 3G or not doesn't make any difference.
The only strange thing is, what i discovered after a few crashes, is that the battery gauge stands still before the crash and after the reboot the gauge drops to it assumed level.
Screenshot as attachment.
System: Android 4.3 Stock (with this last mini patch from last week)
Does anyone have a idea how i can fix this?
I tried, to charge the battery while android is off and to turn android at 100% on, but this doesn't help.
Sincerely,
GTrash81

Did you undervolt the CPU?

If this is happening without rooting/etc... then I would definitely get a replacement. It sounds like the processor is overheating and causing a reboot rather than throttling.

Today i checked if the device is getting too hot.
But after 2 minutes playing Iron Man, by 9°C outside (i was on the way to the city, waiting for the train), it rebooted.
So i started the game, deactivated the display and put it on the table. After 4 hours i checked the game and played over 10 minutes without a crash.
So what i think is, that these two don't like Trim (most new feature with 4.3) or the are badly programmed and must reload/refresh objects while playing and Trim must work to clear temporary files.
And they are badly programmed, because i red at the developers page, that a few other people have the same problems.
So excuse me for wasting your time. But hey, to err is human.

[Q] Nexus 4 random shuts down itself

I got nexus 4, and problem is that now and then it shuts down itself... Battery is charging ok, but after working few minutes or hours (no specific time) it just shuts down (idle or working)...
Phone is not rooted, I tried factory reset, and that didn't help either...
Currently it is on 5.0.1, I got it with this version of software so I don't know did this happen earlier on 5.0 or 4.4...
I wanted to do complete root but i'm afraid that it would shutdown itself during the process..
Does anyone knows what can be the problem??

Have you tried flashing the 5.0.1 factory image through fastboot?

Even I am facing the same problem. But for me it does not show shutting down also. It just blanks out at around 40% battery.

Had the exact same problem with my phone until I rooted the phone and changed to a non-stock rom and have not had the problem since.

Hi guys don't know if this helps because mine is slightly different. Mine is reboot itself.
My suspicion is on ram, maybe the device is out ram and then reboot itself, maybe this goes the same to shut down idk (please correct me if I'm wrong). Recently I've put gravity box and I can see how much ram left when I tap the application switcher, it was mind blowing for me. I often find that when you open several application the number of ram available can reach below 500mb (especially chrome tabs, it do have a lot of ram to use) I mean it's a 2 gb ram device wow. Every few days I've checked that when the idle ram is over a gig I do reboot manually. That way my problem of random reboot vanished. Good luck

Screen will not wake from sleep
The device will randomly not wake from a sleep state, and is happening more frequently. I've read that it's possibly linked to a motherboard issue. I have root, TWRP, Xposed. Will flashing a different kernel possibly resolve the issue?

I bought an N4 from eBay and it worked perfectly for months on stock rooted Lollipop. Then it suddenly started to randomly shut down - not reboot, just a sudden buzz and "Power off". I've tried Marshmallow, Chroma, and now Cyanogenmod latest dailies. Plus a new battery (an eBay special, contacts didn't align with screws, but since another suggested fix was to leave the connection screwless that's fine - it seems to hold a charge and works fine).
So my question is - even though the power button seems to be clicky and ok, is it worth trying a new one? I know that it's mainly suggested for random reboots, but maybe it's related?
Or any other bright suggestions? Any help much appreciated.

I bought a new power & volume button and the same "power off" still happens - sometimes immediately on boot, sometimes after a period when it seems to be going ok..
Anyone have any ideas at all which hardware may be responsible? I doubt it's software, since the same happens on all ROMs, rooted or not.

I had the same issue until I reformatted all partitions and installed stock 5.1.1 Now reboots are gone. Looks like my issue was software related. The only change from stock was stability mode from Root Booster

Thanks, Hjicons. I wish I were so lucky...
As I said, different ROMS, root/no root, make no difference. It occasionally runs for a day or so, but as soon as I reboot it's back to immediate "power off".
On the plus side, it's *astonishingly* strong. I treat all my phones with kid gloves - always in a completely empty pocket, no keys or coins, in a plastic bag if there's the slightest threat of rain (even my water-resistant Nexus 6), I set them down gently on surfaces, yadda yadda yadda...
So in frustration, hoping to jar whatever component into proper life, I've banged it hard, very hard, on a mousemat, all four corners, no difference. And last night in a fury of annoyance, to stop myself pointlessly wasting time trying to fix the damn thing, I tried to smash the front glass with a heavy torch and the handle of a big screwdriver, hard enough to bring my wife in from another room to find out what the banging was. Not a scratch, not a crack. Gorilla glass is as strong as they claim it is.
But still not working...

random reboots/shutdowns

So in the past two weeks I have been experiencing random reboots or shutdowns of my phone. It also seems to have become more frequently. When the phone is off I need to press the power button really long, like 5+ seconds, to get it to start. Does anyone have any idea what might cause these problems or how to narrow it down?
Some more info:
- still on a really old CM13 version (27.06.) / TWRP Hybrid from that time
- haven't flashed any new ROM or modem recently / basically everything is as it was, when it was running without issues
- tried wiping cache/dalvik to no success
Thanks!
Edit:
Flashed cosmicOS. Same issues...
So I found this (put http in front) forums.androidcentral.com/ambassador-guides-tips-how-s/479461-guide-my-battery-shot.html (am not allowed to post links)
And it says: "A battery that's throwing dendrites is one you should replace, even if it's a week old. (There are professors of chemistry and physics all over the world working on why this happens and ways to prevent it. The biggest problem is in early failures of lithium batteries in hybrid and electric cars - 2 grand down the tubes for the manufacturer when that happens to a single cell.) That's why you should look at the second page of the battery stats for a "fall off the cliff" voltage just before the phone shut off or rebooted. A dendrite causes a short. If it's thin and the short burns out almost immediately (microseconds), the phone will reboot. If the short lasts tenths of a second or more the phone shuts off. Either one shows the typical drop to zero in zero time of a dendrite."
Kinda sounds exactly like my problem... So, how do I log the voltages right before the reboot/shut off?

I was going thru the same dam thing and what I did was downgraded and followed some instructions so I mean I lost everything but know is good just get a stock ROM and do what ever they say to do .

Just flashed cosmicOS, same issue. Updated OP. Sounds like my battery is dying after less than a year.

Nexus 6P Random shutdowns/reboots.

Hello,
Forever pretty much I've been experiencing issues with my nexus 6p. I got it second hand but it seemed fine when I got it. Now, however, after a little inactivity, I find that unlock my phone will cause it to crash or reboot instantly. Its right after it unlocks that it does this. It's not every time but it happens a lot. It also sometimes happens a little bit after unlocking the phone after inactivity. Its like when it needs to drain more power from the battery than its used to it will just crash on me.
The only real thing that prevents this is keeping the phone on charge. Then again, it has happened before where it will still die on me. I've replaced pretty much everything on the phone with the exception of the charging board and the main board. So stuff like the screen and battery have been replaced (+more). Not sure what is causing it. I've had this issue before on stock android but at the moment I'm running the final version of Resurrection Remix on Nougat.
How would I go about troubleshooting this?

Good observation. It is true that the reboot happens because of higher performance. It is caused by the four higher performance cores of the CPU starting to work. There is a fix.
What it does is to shutdown those four cores and you will be able to use only four of the lower performance but power efficient cores.
Follow the link :

Sorry for my late reply...
Thanks for the solution, but it seems like a very drastic trade-off for a fix. Is there nothing I can try to fix this like a system or boot.img patch that does something other than disable cores?
Either way, thank you.

My 6p just recently encountered the same symptoms as yours. Only way to keep it from rebooting is keeping it plugged in. I've found something that has worked for me so far, maybe it will work for you too. It seems like disabling the Doze feature has fixed this problem for me. I'm not rooted, so I used adb command to do so. Here is a link for the instructions. Hope this helps you too. In the instructions,
it show you how to enable, but can be used to disable with one simple change.
