HTC DHD freezes up!

Hi all!
Since a couple of days my HTC DHD has been freezing up. Most of times it happens when i take it out of sleep mode. The bottom buttons (home, menu, back and search) do light up, but the phone doesn't respond at all. Sometimes this also happens when using the phone. The screen moves slowely, like a frame every couple of seconds before it freezes up completely. Only way to get it back on is taking out the battery and put it back in. I have installed Cyanogenmod 7.2 about a week and a half ago so i thought the problem might lie there but i switched back to Cyanogenmod 7.0 (which i have been using for the past 6 months or so without any problem at all) and the device still freezes up. This happens twice of more every day! I have wiped everything and updated all my apps and the problem still occurs. I'm really clueless on how to solve this problem.
I can provide a logcat but i have never used that before so i'm not sure on how to do this. Even then, how can i make a logcat when the device freezes up and i need to take out the battery?
Any help would be much much appreciated!!
Thanks!

Did you do a full wipe; all caches, Dalvik e.t.c

The best way to get a logcat is using adb and perhaps a terminal emulator.
Try using the phone without the sd card to see if the problem persists.

Thanks for your replies! Sorry for the late response but had to install SDK and get it up and running.
@ GuyInTheCorner, Yes did all that except for a full wipe. Don't want to loose all my data.
@ Teichopsia, Ok did what you said and i have Logcat running now. Just tested it and it seems to be working. It's huge tho with only a couple of seconds running! Now i have to wait for the device to freeze up again and i can get to my computer while it doing it. As soon as that happens i will make a logcat and post it here.
Thanks for you help so far!

You've changed roms without full wiping? Try it without the sd card to see if there is something in the sd card causing the problem. However, you will probably need to full wipe. If after the full wipe problem persists, check without the sd card, if so, wipe the sd card.
The logcat will help figure where the problem is, but I don't know how to read one.

Meh, chalk one up for you
I agree with Teichopsia, do a FULL WIPE without SD Card to see what happens and take it from there

Ok, so it took a while but my DHD finally froze up again while i had acces to a computer. So i did a logcat. Results are in the Logcat.txt file. I hope anyone out there can read it and figure out what the problem is. Many thanks in advance!!

I started a thread for a similar problem ( http://forum.xda-developers.com/showthread.php?t=1734707 ) but the behaviour you describe is identical to what was going on with my DHD.
Try disabling Wifi and see if it stalls up on you - Mine runs great so long as Wifi is turned off. With it turned on I get random freezes, and the screen not turning on with the backlit buttons lit. Removal of the battery is about the only way to get it to respond again.
I tried changing ROMs, kernels, recoveries, radios and bootloaders with varying results but nothing seemed to fix it.
I ALWAYS full wipe and clear any files relating to the previous ROM off the SD card when changing ROMs.
On 2.2 ROMs Wifi would just turn itself on and off, the phone would not freeze though. Wifi was mostly un-usable as data didn't seem to transfer 80% of the time that it was turned on.
On 2.3.x ROMs Wifi started out doing the same thing as on Froyo, but after about a week it started to freeze the phone and would not return from sleep.
On 4..0.x ROMs Wifi would generally cause a complete freeze of the phone almost as soon as it was turned on.
I hope you find a solution. Mine is the 24 month warranty.

@Max-E-Moose
Thanks a lot for your quick and thorough reply.

Sounds exactly like my problem. I see you have done way more research on this problem then me looking at the thread you started. So i guess the problem lies in the WIFI hardware then. If so, i could send it back for repairs. I also have 24 months warranty. Problem i have, my device fell into a bucket of water when i had it just 3 weeks (about 16 months ago) It never gave me any problems tho! Worked just fine until now. All my warranty labels turned red. I could pull them out and replace them of course. Or tell HTC that it got wet during rain and it was in my pocket. But that wouldn't be honest now would it. A friend of mine has a DHD as well but he tells me he never has this problem which makes me guess the problem only occurs with some builds of the device.
I have been using my WIFI a lot lately for tethering on my laptop. So i will try your solution of turning WIFI off first and just see what happens. Also i will go back to stock rom when ICS becomes available. See what happens ten.
For now thanks a lot Max-E-Moose for your help. I will update this thread if something occurs or i find a solution. :good:

Nope didn't try that. I just ordered a new Samsung 32gb class 10 SD card. Should arrive tomorrow. Will try that first. Maybe it helps.
Thanks anyway.

Any luck ONeils? Updatey?
Due to where I am situated, I have not had the opportunity to bring my phone in yet so am still using mobile data almost all of the time.
I didn't mention before, because I forgot about it, but have you tried using WiFix Manager from the market? I read in another thread that this solved a similar problem for some people.
I think the process is: install WiFix, install the fix from the app, then restart the phone. It should be that simple, if it works - it does nothing for my poor DHD.
Currently using JellyTime Beta 7 and I have noticed that I can turn my WiFi on, and use it for a while, but if I forget to turn it off then the phone doesn't want to wake up once the screen turns off. Wifi hasn't froze the phone entirely on this ROM... Yet.

Galaxy Note N7100 keeps shutting off by itself

Hi,
I have a Vietnam made Galaxy Note N7100 which is almost not usable, unit does not comes with any warranty as it is an export set. It runs on the default ROM and is not rooted. Initially the unit works well for a few hours after installing some apps and did some customisation, after I locked the phone, the phone seems to go into deep sleep. I'm not even able to shut off the phone. Worse still, taking out the battery and put in back after mins do not work. To turn the set on again, I got to take out the battery for a few hours or so, then I can start the unit again.
I initially thought it might be some software conflict, I did a factory reset and leave the phone there for a while, the issue persisted.
It is also not the battery issue as I have use the same battery on another N7100 and it works well.
Is there any advice on what can I do to remedy this issue?
Thanks

This came to me as well, but the set auto shut off before I can even root the unit.

Have a fix for you guys
I had the same problem after some messed up rom flash. If my Note 2's screen goes off for more than 10 seconds, I wouldn't be able to wake it back up without reboot... It was basically in an unusable state. Luckily after 2 whole days of digging I've found the solution.
1. Go to this thread http://forum.xda-developers.com/showthread.php?t=1915386
2. Scroll about 1/3rd of the way down and look for the attachment "BOOTLOADER_N7100.zip"
3. Flash the BOOTLOADER_N7100.zip with Odin using the Bootloader field
That's it!
Good luck guys. I created an account specifically to answer this question. It was a major pain in the ass finding a fix for this problem so I wanted to make sure I spread the fix on this issue so others don't need to suffer through the same thing.

SOS please
i now have the same issue where i tried the liquid rom on my n7100...as soon as it installed my phone started switching itself off within 5 secs and show a red battery light..and no love nor money can I get it on without rebooting..
i tried the bootloader in Odin after re installing the stock rom..but as soon as i select start..it fails??
Anything else?

I am also experiencing shutdowns with my Vietnam unit. I have 4.1.2 original ROM and I tried many possibilities to solve it. No success. The phone shuts off if I start an online radio (or tunein radio) and after max 2 min it shuts off. Doesn't matter if is on data plan or through router.

Had a problem of the phone freezing and had to restart the phone. Then again it would freeze after some time. Flashed stock rom with bootloader and pit but it still persisted. Sent it to the service centre and got my phone back yesterday after mb change. The new mb is with the newer firmware.

note 2 switching off by its self
Had same problem, I switched of data, wi-fi bleutooth, gps, switched them on again 1 at a time.
Phone worked ok untill bluetooth was on again, then it shut down. I think the problem is with Bt.
I emailed samsung support who suggested i connect to kies to check i had latest firmware but i
knew i had, they also suggested a factory data restset, (settings- back up and reset- factory data reset).
Did this last week phone has been working fine since.
Hope this helps.

Same problem here, BT not working and my Note hangs every time the screen shuts off. I can wake it up immediately but after 8-10 seconds I am unable to turn it on again, must hard reset or take off the battery... No solution found so far. Flashing stock fails on sboot.bin also...

Weird Problem, Note 2 hangs very frequently now

Hi All
Few weeks back, my note 2 used to hang once in about two days and I thought it is normal. Lately, it is giving a lot of problems as it hangs as many as 40 times in a day, that too for no reason at all.
To make it work, I have to restart it by taking out battery or long pressing the power key, and sometimes doing so even 10 times doesn't solves the hanging issue. I am on stock rom 4.1.2 (India) fully updated and never rooted.
Do you think maybe RAM or the Processor is at fault. Is there anyway or app to test these for defects.
Although it is painstaking but I am planning to reset the phone, do you guys think it will help?
Any chance my phone is heading towards SUDDEN DEATH, are these the symptoms?
I am so fed up of rebooting it again and again and in the process missing important calls.
Help me deal with this situation guys..

Sent from my GT-N7100 using Tapatalk 2

It is usually because of the bad update or the high usage of the storage (keep in mind when you used the first time and compare it to now, there is a diference) the best that you can do is to do full wipe as they said but if this doesnt work try to update using emergency firmware (or something similar) via Kies it must be enough.
If it doesnt help then is a problem of the device itself or maybe the official update if more than one is having the same issue
Hope it helps to you, bests

Factory reset solved my problem for now but overall the phone seems to lag a bit, but not a cause for concern. I guess the hangs were largely due to number of messages stored, call logs and maybe some applications.
Though there was one weird thing, when I connected my phone to kies for backing up, the firmware section displayed that my firmware version is not allowed to update via kies.

Absolutely same issue , in my case even factory reset hasnt worked. Have tried unmounting the externl sd and kept very basic vanilla apps. It hangs every time i interact with the screen and the only wy out is to hard boot it.
PLs help if someone has the same issue.

Had the same problem with rebooting only was 2-3 times a day. Changing to a different firmware fixed it. Download a newer firmware wipe cache, dalvick and factory reset then flash new firmware. Hopefully will fix your issues guys.

I had the same problem
1: Did a factory reset
a: didnt install anything...the moment i went to set up the email it hung.
2: Took to the service centre
a: He reinstalled the stock ROM. After rebooting and while setting up the device it hung again.
b: Tomorrow they will either changes the PCB or the screen depending on what the tech feels is the issue.
Regarding memory... after a reset it shouldnt have hung. + have tried it without the 32gb card also.
Will let you know what comes out.
But yes it was working fine and all of a sudden it started hanging last few days.

the strangest thing is that sometimes the screen doesnt respond to touch EXCEPT the notification bar, it goes alright in that area, I can even toggle the buttons and swipe away the notifications, but if i close the notification bar, open it again, ANY action (swiping notifs, clicking button, etc) would instantly hung the phone. strange eh?

i had the same problem, and i checked my emmc and it was the one that has the bug. Just finally got the SDS today.

I'm in the U.S. and we don't have a service center since these phones are only for International. Samsung USA says they won't fix it, and EU says we aren't EU residents. I have the same chip.
The only place i found so far is http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-note-ii-emmc-chip-repair-replacement/ and they charge $150. They have a facebook that mentioned that were able to get the emmc chips this past week and have now started to do repairs.
They are located in Texas so I'll be sending my phone to them this upcoming Monday. We'll see how long it takes and the turn around time. If anyone else has tried them, please let us know how long it took.

Send your device to wherefrom you bought it. As long as you have your invoice, they have to fix it.

went to the service center and they say they'll replace the circuit board on monday, no questions asked

Hello!
I'm glad (unfortunately for us) to see that some people have the same issue. I bought the phone on November and I have the "hangs" since 1 week. Hard reset didn't solve the problem for me, even without restoring my backups or apps. I tried to remove the SD card, and the problem persist.
I think the SDS problem is not exactly this one, but It may be related.
Today, I'll go to the seller and I'll see what I can do...
Thank you for the information! I'll post with the updates of my case

Tab S 8.4 WiFi, after 6.0.1 update, restarts, white streaks, erratic display touches

Malfunctioning on Marshmallow update from Samsung.
I was going to install Cyanogen OS, but haven't yet.
The update from Samsung to M 6.0.1 seemed to go ok.
But, now I have errant screen touches, abrupt restarts for no apparent reason, and white streaks flashing on the display (intermittent).
It works fine for a few hours, then wacky again.
Is there anything that I can do?
This is the 8.4 WiFi only version. TM-7400 I believe.
No apparent damage to the display, no water damage recently, or ever.
Thanks!

I just now booted in safe mode. Seems to be working OK, but it has worked OK for hours after having the glitches the past couple of days.
Should I remove the SD card? Maybe an app on there is the problem?

What apps do you have? Use this and post a list.

Anyone?
I updated the few remaining apps which required it, and it's run fine since my OP.
I just now saw a white streak on the display, and a few seconds later it restarted by itself.
Thanks.
And, how much time involved in flashing Cyanogen Mod for a first time ever having done it?

Sorry, I didn't see this reply. I'll post apps list shortly..

What you need to do to fix this is:
Open tablet. Pull battery out for 3 minutes , pop it back in. Close tablet, your tablet will be fixed

Removing the battery is not only troublesome but seems a little unnecessary.
You should try formatting all partitions through TWRP and reflashing the 6.0.1 firmware using Odin. I did that and have no issues with my device.

The 3 symptoms this dude has are what the battery issue have. Pulling the battery and getting into the inside are not difficult with the correct tools from Amazon or eBay and tutorials from YouTube. This fix has worked with my gfs tab s

While removing the battery can be a good idea for removing leftover electricity from the circuits and probably fixing those issues, if not careful can end up breaking some component.
He said when booting the device in safe mode all issues disappeared, so flashing the stock rom using Odin probably will solve all problems.

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?

I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.

I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

its something completely different to this topic

I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.

Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)

Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.

My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.

Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.

Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.

Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.
