[Q] My DHD keeps crashing and rebooting, but only when the screen is locked...

Hello!
For some time now my phone's been rebooting itself completely random it seems. I just got it back after sending it away to get this issue fixed. Obviously the "repair" didn't really do anything at all. All they did was to flash the latest software apparently.
I got quite fed up with the crashing and rebooting stuff, and figured that it wouldn't hurt to try to flash a custom ROM, in this case I chose to root the phone and try MiUi. I had no clue wether it would solve the issue I'm having, but I figured it was worth a try. So i rooted the phone and flashed the latest version of MiUi (1.11.18).
At the start it seemed like it had worked, and had stopped the phone from crashing. But after some time I realized that the issue is still there, only difference now is that it ONLY crashes when I lock the screen with the Power-button. EVERY SINGLE TIME I do this, in a matter of minutes it will either reboot or just turn black and totally unresponsive. Only way to get it on again is to take out the battery and put it back in.
This is starting to annoy the **** out of me, so I talked to my brother for advise this morning, and he told me to wipe my Dalvik Cache. So I did, and nothing changed, the phone keeps on living it's own life.
I have absolutely no clue what info you guys might need to help me with this, but I'll start with this:
Phone: HTC Desire HD
Android-version: 2.3.7
Kernel-version: 2.6.35.14-cyanogenmod-g319b6e2
ROM: MiUi 1.11.18
Also, the motherboard's been switched once, cause of another issue that is now gone.
ANY help is appreciated, I just want to be able to use the phone normally!
EDIT: Also it seems that the phone won't reboot or crash whenever it's charging.

Sounds like a hardware/software issue your best bet is getting a replacement and re rooting .

Random reboot?

So, I've had the premium for almost 3 weeks now. On the second day it crashed whilst I was listening to music +browsing in chrome. Thr screen turned inky and then turned off. Since then I haven't had anything similar happen, but I have had 1 or 2 reboots. Are these signs something could be wrong with my phone? I have like a week to get a replacement. It's rev 2, other than this I have no complaints.

Try to remove cach in recovery mode, maybe that will fix your problem. If not let me know

This has been happening to me as well and actually results in boot loops. Since I have Liveboot, I can see the dmesg output. It says "Failed to start system services. Invalid abi: ABI" or something like that. I'm RomAur so maybe that has something to do with it?

It has happened to me 3 times this week. Also RomAur 1.1. It seems to happen when i am heavy multitasking, definitely related to chrome I think.

I'm completely stock... I use chrome as my main browser. The last time it happened it froze on wake whilst it was charging... The first time I was listening to music and doing something else which I can't recall. The phone has 3gb of ram so I don't really clear my recent apps as often as I did on my S4. It happens once a week on average for me. Cache wipe didn't do anything.

You could've easily gotten a faulty device. A but load of hardware issues can do that and I would advice you to do a factory reset, update to the latest F/W (flash it if not available in ur region), see if it happens again and if it does - get a replacement
Gd luck

If you're totally stock this might not help but I narrowed my problem down to xposed being unstable as crap on mine at least. Hasn't happened since I went back to stock fw (using. 200 generic FR). But I tried to install xposed and I got the three light reboot immediately.

exactly like that on my z5 . when i flash the xposed uninstaller , it doesnt randomly reboot, but when i flash xposed , it does.i was thinking of flashing .200 ftf and then flashing xposed from the beggining (before i install any apps ) to see if it helps , but you said you did it??

PLEASE HELP ! Infinite Boot Loops . Flash PASS But Still Boot Loops

Hello Ive Never Been The Person To Post My Problems because somewhere along the line someone has the same problems as me and i usually find a fix or a flatout yes or no if it can be fixed or id take it upon my self to mess with . but seeing as how this is my first ever decent phone i dont want to mess it up any further than i already have . what i can tell you is that i was switching from the renegade rom Debloated back to a backup i made with twrp after i only rooted it no rom installed on that backup . i didnt like the renegade rom debloated so i wanted to go with the full version however somewhere in between me flashing it just started a boot loop of Optimizing Apps 1-32 then before its even close to being it reboots. so i went and downloaded the latest 6.0.1 firmaware and reflashed . and the same thing is happening and now in download mode it says i dont have an meid and my CURRENT BINARY is Samsung Official But my System status is Custom FRP Lock OFF Secure Download Enabled . i can get to normal default recovery and i can still flash TWRP in odin and use it on my phone . ive exhausted all options ive found online . i would post a logcat but i dont have android studio . last time i had it for some reason it couldnt fully install .
Edit: It makes it to optimizing apps 1 out of 32 then cuts at 31 then reboots and does the same thing all over again
Edit 2 . on back it says model is g920t but everything on the phone says g920P . so I don't want to use .pit yet cuz I don't know what I'm really working with . the phone is sprint but the model letter T is for T-Mobile . so the previous owner unlocked it I assume . so I knows there's more to it than what I can see
. i dk what else to do im screwed .

Yea if its a tmobile thats the issue trying to flash sprint. Now a while back we were haveing issues with lg g3s and g4s being knockoffs. Being sold as refurbs made from many diffrent model nums. Which were causing loads of problems. If the model says tmobile u should only be using tmob firmwares and such. Kinda weird do a serieal number check and see what ot shows it as

hi im having the same issue here, my phone is sprint, i got it unlocked for tmobile, i was on team spr PB6 version, i decided to update to renegades pg1, so i used odin to flash pg1, then i flashed Renegades DB, everything was working fine, until the rom control settings werent working so i thought it was a bad flash, Reflashed renegades and everything seemed to be going okay, until it went to boot, it said "installing system updates" blue screen with a loading bar, it went to 32% then said erasing then booted up, thought that was weird, then it went to android app optimization, it wouldnt pass that screen it just randomly restarted but eventually it went all the way through and phone booted up, but now the phone restarts randomly, ive gotten it past the first screens (inputting wifi passwords the account screen all that stuff) after restarting numerous times i finally can look into the about section for 5-10 seconds before phone restarts, i noticed the imei and all other settings in "status" are either not there or say unknown, also the baseband says version unknown.
anyways im wondering if anyone has any help or can lead me into a direction to fix this. i really need my phone for work and ive been out for 3 days trying to figure this out, hopefully i can fix it and someone can help me. thank you for your time.

Its a long shot but it fixed my phone ... let it fully die then charge it and turn it on

Just wanted to confirm, i let my phone reboot itself all night till it died, plugges in the phone for a bit and turned it on. Works magically. Who knows what was wrong thank you for your advice. Looks like my prayers are anwsered.

Common S6 issue, seems to fix most phones with this rebooting problem

n910p started freezing since MM , why?

Hi
I've been going back and forth for a couple of days now , thinking if i should post this post or not .
so here it goes , i had a n910p for a couple of months now it was on 4.4.4 when i got it and it worked just fine no problems except some dying battery related problems -phone shuts down when using the flash camera, the phone shuts down without any warning and then i find the battery at 5% when turned back on - ( i didn't know it was a battery problem back then ) , but everything else was just fine .
-i should mention i'm in Jordan not the US so the phone is unlocked sim .
So i wanted to upgrade to Marshmallow maybe the problems got fixed , so in order to upgrade to MM i had to first upgrade to 5.x.x and i did and tested it for a couple of days it had some Freezes but nothing unmanageable , i changed the battery while i was on 5.1.1 there was no problem here no freezes no random shutdowns .
And then i upgraded to MM that's when the problems started to show one after the other , all described here and add to that i had to add and remove the battey 3-4 times in order to turn on the phone.
so i thought to my self it started since i upgraded to MM , maybe if i downgraded to kitkat it'll go away .
i downgraded to 4.4.4 not the stock just to see if it was any better, and it was !!
no freezes no random shutdowns except for one problem if i wanted to shutdown the phone or do a restart i had to remove and add the battery in order to get back on .
so my question is , why is this happening ?
is it a hardware problem and just my luck it started popping out when i started upgrading ?
why is it there is less problems when i downgraded to Kitkat ?
P.S: i upgraded to 5.x.x first by flashing it, because i couldn't upgrade OTA .

This problem is a little confusing and beyond me, but I have to ask and suggest one thing.
Instead of doing OTA, Have you tried to just use odin to flash the Marshmallow firmware you want?

Odin MM like suggested.. Don't do any mods. If it persist, then you might be looking at faulty hardware ie main board.

i just flashed MM after reading your replay , and will test it out.
any tips on what to do with the phone if it's a hardware problem ?

so right at the first boot i had this error shown in the images (attachment)
i removed the battery and restart the phone and it booted correctly , the same problems began to show freezing random restart and it keeps booting to recovery and i had to add and remove the battery a couple of times to turn the phone on .
i returned to stock 5.1.1 apparently it's the most stable thing i can use right now , honestly i'm puzzled on this problem i'm quite sure it's hardware and software somehow and if i send it to a local shop they probably will say "i don't know what seem to be the
problem "
so i'm just going to keep using it until it becomes a replacement parts for his other brothers . :crying:

I'm no expert, but i've poured through dozens, maybe hundreds of pages about this issue. Happened entirely with MM, and most people have thrown their hands up calling it "faulty hardware".
All the accounts, the symptoms, the timing, and the root problem (eMMC error) point to a bug in MM that messes something up when it installs itself- *sometimes*. Those unlucky enough to catch this bug are stuck with it, and end up with essentially a brick or returning it.
Hardware doesn't make sense, not when the issue completely coincides with an update. Unfortunately, I don't know how to completely 100% wipe this device and re-load it from scratch, which is what I think it's gonna take. I don't even know what all *can* be wiped 100% :/

Here is the thing though (I have the same issue). If you remove the battery and put it back in, say 30 seconds later, it won't turn on. If you remove the battery for like 5 minutes and then put back in, it might turn on. I'm talking about the first little vibrate it does when holding the power button to turn on. It really acts like a hardware issue to me. The only work around that has worked for me is an app called wakelock. Using this app and selecting partial partial wake lock makes the phone run completely normal.
What REALLY sucks right now is that I have an OTA update waiting for me and the phone needs to reboot to install. The phone won't reboot. When it turns off, it won't turn back on without removing the battery for 5+ minutes.

IT is the MM Update
Im not an expert or anything but i have the same problem cant update cuz phone has to be restarted i finally had enough of it took it in told them (sprint) to update it thay said thay did but thay didnt. Called and thay couldnt fix it so i said the heck with it and i flashed it still doe the same must use wake lock app wish someone could figuer this out.

Yes having the same issue as well but now even the wakelock app won't keep it. The phone wil stay for maybe an hour, then reboots and will continue to reboot until I take the battery and then start it again afterwards. The length of time the phone stays on varies really and it could be as long as 3 or 4 hours, but it will definitely reboots itself, I cannot got 1 day without this happening. At this point the phone is unusable. I am on another phone at the moment.
I did flash the MM updates (even went back 3 or 4 older versions) using ODIN and same issue. I am debating whether I flash an older Lollipop version and see if that makes a difference.

[D855 32 GB] Reboot problems (brick or hardware defect?)

Hello guys,
I managed again to brick my phone.
I flashed Fulmics as I wanted to swap from those not fully stable nougat roms. Well, I have no idea what caused my problem - Fulmics run without prolbems for a 2 or 3 days including xposed etc.
Then today I changed my ChromePie options and that's when the reboots began. I don't know if this the real cause was though.
So I tried to flash another rom but always got random reboot even in recovery after few minutes/seconds. So I went all the way back to stock rom (4.4.2) with LG Flash tool - which worked after a few tries. Then I installed MM rom via .kdz file and flash tool 2014, which also worked after a few more tries. But then the reboots started again. Can't say if the 4.4.2 rom was without boots because I updated to 6.0 quite quickly.
The strange thing is that after some reboots phone won't boot again and I have to take and leave out the battery for some time to boot the phone again.
Any solutions for my problems?
Best regards

..bumped into the same 1/2 year ago. Didn't want to put to much effort so,..went to stock and back, worked for me.
Good luck.

Which stock and how did you go back?
As mentioned I already went back to stock but the issue kept occuring.

Hi, got the same problem with my G3
wi fi and bluetooth didn't work and phone loop rebooted
Here below the steps I followed to solve
1) First attempt (didn't solve): had cloudy rom, got back to stock official but still rebooting, tried fulmics and other rom but problem persisted.
2) second attempt (didn't solve): went back to stock and changed battery (found somewhere in internet), now I have a brand new battery but a phone still loop rebooting
3) third attempt (SOLVED): found that the wi-fi / bluetooth chip (one for both) copuld have unwelded and solved so (it appears I can't post outside link, delete spaces to have the correct link):
youtube .com / watch?v=1zWpzYh2DPI&t=15s"
youtube .com/ watch?v=6_0jzp65eLY&t=256s
Now i'm on fulmics and no more loop reboot
Hope you can solve
[sorry for my english]

have to say restoring and/or flashing isn't always that stable. I've experienced it sometimes needs a 2nd try.
Hopefully it isn't a hardware issue in your case.

So I tried all of oyur suggestions but nothing seems to work.
On the contrary I ended up in a status where I can't even flash a new firmware.
In LG Flash Tool 1.8.1 I get the error

In LG Flash Tool 2014 (flashing MM with kdz file) phone shuts down in middle of process.
But I can still access Download Mode.

No more ideas?
I really think I finally broke my phone... But the fact that I can still access download mode keeps my hopes up.

So, after 2 months I just tried to reawaken my phone. Still the exact same problem. It just keeps shutting down aber some while, but just when I start flashing something. If it stays connected to computer whitout doing anything it can stay on for like ever.
Can anyone confirm that this could be a hardware defect?
