Diagnosing hardware failure - Legend General

For the past few days I seemed to be getting a lot of random force close errors on my legend, with no discernible pattern. This continued up to the point where all of a sudden pretty much every app crashed and wouldnt remain open more than a few seconds. I then tried to reboot, and since then the phone just gets stuck in a bootloop at the rom loading screen. I've tried four or five different roms, all with the same error.
I would assume this was a memory/processor malfunction, however the fact that I can still flash roms and make backups with clockwordmod suggests to me the hardware could be ok? Does anybody know of some sort of diagnostic rom I could run to check this?
Thanks guys
Matt

Here's some stuffs to check out, don't over clock, Max 600mhz, not every phone can be oc'd, maybe even try less processor speed say 480 MHz. Have u been ocing your phone on extream speed for long time, like 806+ mhz, that will kill a processor for sure.
Have you done a fix permissions with clockwork mod? This can help heaps with fc's.
If using an ext partition which type are you using 2 3 or 4, apparantly if your using ext4 and your phone is crashing it can cause even more issues.
Using lots if widgets on your screens?
Have you tried a different/new SD card?
My understanding is your rom space can eventually fail if your flashing lots n lots of roms, but you said you can flash successfully, so that sounds good.
There is a few to start you off.

Amazingly I have managed to completely fix the problem. In a last moment of desperation before buying a new phone I decided to try wiping the battery stats, simply because I had never tried it before (didnt see the need to). Miraculously this did the trick, and I managed to boot into cyanogen 6!
I then restored a backup I made when the phone first died, and confirmed it was still broken as I expected. I then wiped the battery stats , and viola it worked!
I have no idea what is stored in the battery stats, but I am very surprised this made a difference. Thanks for your help anyway ranger.

[Q] Please Help..I am at my wits end..

I have an HD2(of course)...i have tried many many roms but am stuck with the same issue..I have random freezing issues..i have tried different radios, different classes of sd cards..tried adjusting the vm heap. but to no avail..i am currently using frankenstine rom it seems to be the smoothest but i still have freezing issues..when this occurs i can only pull the battery to reset it and sometimes when i do this i must pull battery 3-5 times to get it past the magloader screen.
i have asked this question in many of the rom threads that i have used but have never gotten a clear and definite fix..can someone enlighten me on how to cure this issue it is really becoming quite frustrating.. thanks in advance to anyone..
When do you have these freezing issues?
When you're watching a web video? Playing a game and listening to music at the same time?
If so, it's cuz you've run out of ram, so your phone will lagg to death. So get a task manager to close those apps.
If not Iunno what your problem is.
Note: Try not to pull out your battery, instead use the soft reset button. If you keep pulling out your battery, you'll mess up the pins.

it doesnt seem to be specific on when it freezes..but usually when only using 1 program at a time..i do use task manager.i recently installed words with friends and almost every time i try to open it, it will freeze.

yes the last time i flashed i used task29..someone once told me it was my radio..which ive tried to downgrade to an earlier version but that didnt help either..
I think it's ram. Reason being, if it is from opening an app, it may be the app is using too much memory for it to handle, eg. mega jump is one
Never tried words before though, but it doesn't sound like something that uses a lot of memory but Iunno.
Do you use desire hd or z builds? Those leave very little ram left.

my current rom is a desire build..what build would leave more ram?
i am going to try yet again to reflash this phone and task29 it..
Any non sense build will give you 210+ ram free.
what radio are you using? had some freeze moments when i first started fiddling with android. upgraded my radio to 2.15 and never had a freeze ever since.

yea i got this radio also...
ok i rewiped, reflashed, task29'd it last night and thought everything was a-ok until a few minutes ago when yet again it froze. i cant wait till tmobile comes out with an htc phone with the same screen size as the hd2 but native android cuz ill be all over it..this crap gets old quick..i cant believe i am the only one with this unfixable issue.
did you also fully refresh you sd card? not much point task29'ing, reinstalling android and starting over if your sd card is still full of cache/droid system folders/EXT/Dalvik and what not.
that being said, if you have had the phone since way back last year, a good proportion of the early ones had freezing problems, regardless of rom.radio, and a quick warranty swap was usually the answer.

i did use the recommended panasonic formatter..and also the cmw format,dalvik and cache wipe...
your other comment kinda makes sense..i have had this since i think February of last year.
so after speaking with tmobile, and actually reflashing windows 6.5 and having it freeze on me twice and today it got stuck in a reboot loop, I am getting a new HD2..i sure hope this one does not freeze as much as my current model..if tmobile would come out with an android phone with this big of a screen i would switch.

Random HD2 Freezes!

Hi guys. I've been running the Android Stock Desire build from Cotulla for a few months now. Every once in a while I'd get a freeze, but then a battery in, and out would fix the problem (usually within the first try. sometimes I need to do this a few times, but no more than 5 times)
However, since last Friday my phone has been crashing like crazy! Constant crashes at random stages, and even reboots. Removing the battery also didnt guarantee a fix. I think I may have tried it about a hundred times, and Android just crashed at a random point in time during every boot. Eventually it booted, but since then it has crashed again! I figured that perhaps I should try a newer build.
I've decided to try out this build: [08.MAR.2011][CWM]TyphooN CyanogenMod 7 RC2 v2.5.4[2.3.3][A2SD/RAM][rafpigna OC 1.8]. Since I already have radio 2.15.50.14, these are the steps I've taken:
- Flash Task29 (ShaDrac version).
- Flash MAGLDR 1.13
- Flash ClockworkMod Recovery v1.3 135M System
- Flash CM7
Now, even during the various stages before flashing the CM7 rom, I would get freezes during the MAGLDR 1.13 bootscreen, or recovery won't load and I'll get stuck on the GOGOGO screen. Also, copying the zip file over in the MAGLDR mass storage mode won't work, and causes a freeze when I start the copy. Reset, or Battery removal seems to get me to the next step again.
Eventually I've flashed CM7, but now it freezes at the setup stage.
I'm starting to think maybe its not the various Android builds that I'm trying, but perhaps the problem lies somewhere else on the phone? Any ideas? Is my radio perhaps not the best one for the phone (even though its the latest)?
Any help will be much appreciated.
Regards,
XA83
Shameless bump (hope I'm not breaking any rules!)
I realize this post should have probably been under the CM7 thread as well, but I don't have access to that yet due to my low post count...
Could be:
*Wrong CWM Size, check in the rom thread for information
*leftover data, task 29 and reinstall everything
*Corrupted data on SD card, try booting without sd card to see if this is the case.
Thanks for the reply.
I've removed both the SD card and the SIM card. Phone seems to work flawlessly. Boots CM7 without a hitch. Next step I've added the SD card back, and formatted the card from the CM7 settings page. Still perfect.
I've tried it about 5 times now and every time the SIM card is not present, the phone works like a dream. Every time I put the SIM card in, CM7 crashes within the first few seconds of showing the home screen.
Finally, some progress!! Thanks again for the assistance. However, what dis this mean? Could this be related to the actual SIM card I'm using, or does it have to do with the part where it initiates the network connection and possibly the 3g connection?
*Also, just for information, I believe that I do have the correct CMW size. The build indicates "Flash ClockworkMod Recovery v1.3 135M System" which is the one I've flashed.
maybe reflash back to winmo then do evrything all overagain to android
I doubt it's an issue with the phone and its initiating with the sim card. Just replace the sim card
the SAGA continues
Hi Guys,
So since my last posts I have actually managed to get the phone running Typhoon's CM7 and its been working great... for a while.
I'm currently on version 3.0.4 and I still get:
1) Freezes,
2) Reboots,
3) SOD,
4) This happened today: phone cuts mid-phone call and makes a loud buzzing noise until I pull the battery.
I'm thinking more towards hardware problem at the moment, but please let me know what you think, and what I can do to debug the sitaution. Is there perhaps a hardware monitoring app that I can install that logs the whole system every 1 minute that I'll be able to pick something up.
I was also thinking maybe the phone overheats. As explained in my original post, whenever a crash or reboot occurs, it would sometimes not restart the first time round after pulling the battery out and putting it back in. Sometimes I get crashes even during the MAGLDR stage with "fatal hit" and strange things like that. Or even when I boot into CWM sometimes.
Now, to test this overheating, I've experimented with placing my phone in the fridge for 5 minutes after a crash. Thusfar I've done this 3 times, and every time I get a clean boot when I put the cold battery back in and then the phone functions perfectly for a while.
So, overheating, or do I perhaps need another radio? I'm out of ideas.
Any help will be much appreciated. The problem now is that I'm so used to android that I wont be able to go back to winmo or even blackberry

XA83
it happens to my phone, and did on my previous HD2.
I've tried every build, task 29, every radio...new sd card....everything.

Are there any apps we can run to test battery temp, cpu temp, cpu voltage or anything like that? I'm pretty effecient at debugging PC hardware issues, but when it comes to my phone I feel like I'm back in the stoneage!
Please help
I have tried over and over and over and over on this kind of issue.
most if the time was some unfinished coppied file which can;t runs properly on roms.
Try to asks ROM developer.
- SD partition : how many partititons?
- SD partitions : what kind of partitions, is it using etc 2/3/4, does it comes with swap etc?
- Installation method : does it needs to clear phone ROM with cwr ? what is the size?
HD2 usually I will go for 400M size
- config.txt settings for SD/NAND.
A proper guide could helps you on in the installations
If you guys are having overheating problems resulting in freezes, you might want to use SETCPU and set a lower maximum frequency. Something like 800-900 mhz might keep your cpu's from getting too hot. Or maybe setting it to a different governor could help too, idk for sure.

Possible solution, Thanks mate,
I changed the CPU speed to 1036 Mhz from stock 998 Mhz speeds and haven't had a Freeze yet,
before that The touch screen would freeze occasionaly when there was a lot of activity like in games such as fruit ninja ....
a Lower CPU speed such as 806 Mhz also seemed to do the trick ...
I don't understand why the Freezes would occur at stock speeds ...
I'll have to give it a few days though ...

Update:
Tried that with Interactive Governer, it still freezes on odd occasions, and the battery temp shows 33-36 Degrees Celcius on load when running games ...
i'm beginning to think the freeze is temperature related, as it never freezes while it's cool ...
I'm going to try running it with Smartass governer and see if it makes any difference ...
regards.
Yeah, there's been alot of HD2 owners who've had high-temp related freezes, one guy even went as far as to dissassemble his phone, re-bond the cpu to his mainboard, and add a home-made heat sync to prevent further overheating (successfully)
I just figured changing the cpu freq or governor might reduce cpu load, or increase efficiency, resulting in less overheating. But I feel pretty confident in saying that you guys' freezes are very likely coming from heat. It was even a problem in stock WinMo roms

Yawp, I can barely charge my phone with the silicone case on anymore and that's in ac (the AC in my house is usually set at 74F) I have noticed I get freezes at 36C however I can go to the beach and get it up to 44C and it runs flawlessly

Thats wierd, I'd have thought that such a High Temp as 44 Degrees C would cause more freezes ....

i'm getting freezes from cyanogenmod android too. i recently restored my ROM to the original 2.13 and believed to have all previous settings related to android deleted.
freezing
i realy didnt undrestand what the exactly means of freeze, my phone freeze after change rom ,i can't use "TyphooN CyanogenMod " becuz my phone freeze at the android logo and it didnt any animation to boot !!!
i have hspl8 , radio 2.15.50 ,Recovery_130M_system_4M_cache[v3.0.2.4],mgldr 13.
i install windows then install android but it steel frezz, i can install just HyperDroid-GBX rom !!
it this problem fix with cpu temp ??
i get it in Refrigerator still feee !!
Temperature
Hi guys. It's definitely the overheating causing all the freezes. I've now succesfully "fixed" my phone 11/11 times by placing it in the freezer and then it works flawlessly for at least a day.
I'll try setCPU to try and lower the CPU frequency from stock and prevent heat issues.
However, ideally I'd like to return the phone to the manufacturer as a defective one! Only problem - how do you convince the 'genius' tech guy that the phone overheats. Last thing I want is to send the phone in, and only get it back after a few months with some response that they found nothing wrong.
Hence, I'm still looking for some sort of app to prove in a way that the overheating is causing crashes... At least in that case they may be more likely to issue a replacement immediately. Any ideas yet?
Regards,
XA83
Just a follow up:
My phone has been sent back to HTC. After a long wait, tech support said they replaced the hardware components - I'm assuming the phone mainboard.
I've reflashed CM7 since, and it hasn't crashed a single time!
Verdict: Random freezes was caused by hardware problems on the phone, and the crashes was most likely due to overheating of the components.

[Q] Random lock ups freeze

I keep getting random lockups, at least more than once a day, and sometimes several reboots in a row.
It appears that i can happen almost any time, whether it be at a lock screen, while titanium is asking for root, or opening twitter or facebook, even the gmail app. It simply freezes, and requires me to long press the off button and reboot.
Unfortunately, i can't get adb via usb to work on the nook, so i can't get a reliable logcat.
Is this common? I have had two nook devices so far, tranferred the rom over through nandroid and have had lock ups on both, I am flashing regular cm7 nightlies now (emmc), but it occured using phiremod too.
Help?
I never had one, maybe I'm lucky
Have you tried fixing permissions in clockwork?
Sent from my LG Optimus V using Tapatalk
I am having the same problem. I loaded CM7 to my emmc yesterday and I have had it freeze on me a couple of times now. All have been random. I do have performance set to 1.1 and on demand gov set.
So I can just go to ROM manager to fix permissions? Hopefully that works.
EDIT**
Did not work. Was fine, then I uninstalled market updates, connected to wifi, opened the old market, searched for flash and it froze up. Any ideas?
EDIT 2**
uninstalled beautiful widgets (read that somewhere), so far no lockups (fingers crossed).
i had mine lock-up twice last night
i was in dolphinHD and i had just installed swype beta
i have only had 1 time that it has locked up before then in the last 1-2 months that i have had it.
im blaming swype, since i havent had the problem in the past
perhaps not your problem, if you dont have it installed.
I get lockups pretty regularly. It's irritating. Not sure what the cause is. I thought overclocking had something to do with it but everyone else is overclocked and this problem doesn't seem to be common.
How low do you have the voltage settings in tweaks? Having a voltage just barely too low for your CPU can cause a lot of weirdness. Also, it could be any one of the stepping voltage settings, not necessarily either the min/max frequency.
Folks, playing with the voltage settings in nook tweeks is not for the average user. These settings can really bork your nook. That's why you get a warning when you open those settings.
That being said, I have been running cm7 on eMMC for months and have never had a lockup. I am overclocked to 1200 mHz but have left the voltages alone.(cm7.1 nightly 160).
If you are running on eMMC,try fix permissions first. If that does not help, start looking at the apps you are running to determine if one of them might be the problem. Several people have reported issues running beautiful widgets. There are other apps that can cause issues. If you have good backups of all your apps, try removing apps one at a time. In the process, you might learn something about your system.
Worst case, reinstall cm7, wipe data, cache, and dalvic cache. Start over with a clean system and add your apps (apps only, not apps+data) one at a time. This will ensure that a possibly currupt data set was not causing the issue.
The key to a fast, well functioning nook is to start slowly and ensure each change works well before moving on to the next step.
While it's true I have more time than most to play (retired), my nook can run circles around most competitors but only because I took the time to set it up right the first time and I am not afraid to wipe everything and start over.

I fixed permissions some time ago, seemed to help a bit, but i still get the odd lock up or two. I am running Swype and Beautiful widgets(anyone know a good alternative?)
I had been getting irritated by these these random locks up for a while. It seems that uninstalling beautiful widgets fixed the problem for me. I thought it might be that BW was trying to access the GPS, but it still locked up after disabling geo location in BW.

In case you're still interested, BeWeather is a great substitute for BW and FlexT9 in place of Swype.
Also, I had issues with lockups no matter my overclocking and formatting the eMMC and possibly reseating the SD card fixed it.

[Q] Bitter Sweet MT4G, Always Freezes immediately after booting.

I finally got a Glacier.
Only problem is that it freezes, I thought this would be an easy fix but after rooting, getting Radio S-OFF, installing Eng HBOOT, CWM, CM7.1 and newest radio. It still freezes 5 seconds after booting.
I got it off ebay so no returns.
It doesnt matter which ROM/Radio/Recovery or combination thereof I use. It will not stop freezing. I'm now back to stock 2.2.1 everything, still freeezes.
I have the 'good' EMMC chip and it passes all tests. Odd thing is it never freezes in Recovery/Bootloader. Doesnt matter if I'm there an hour. It wont freeze.
Any ideas on how I can get to enjoy my xmas purchase?

Ok, I've just tried that. No luck. Also noticed it doesnt freeze when its on the charger, hardware issue?
I'm thinking since it doesnt freeze in recovery or when charging maybe there is a CPU voltage or power requirement that makes it work. I've installed SetCPU and I'm testing different values and scaling options. Any idea on which scaling option might work?
Well, if it doesn't freeze when it busy, you could try raising the minimum cpu speed. Battery life will blow, though. Or, you could try raising the voltage on the lowest speeds. These could also be combined.
As far as governors, you could see if low cpu speeds cause freezes by trying the Performance governor. It will lock the speed to the max setting.

Help! Note 4 freezing, crashing and constantly rebooting.

Its been a long time since iv been this stumped, about a week ago my phone started acting very strangely, laggy performance, freezing randomly and occasionally rebooting itself, now its getting worse, getting to a point where the phone is probably rebooting itself 5-6 times a day, iv uninstalled every app, iv factory reset it, wiped cache, replaced battery, removed the SD card (in case of file system corruption) using Samsung Smart Switch did an emergency flash back to original Rom, installed every troubleshooting app out there, monitored RAM and CPU usage, all i can see is that the CPU suddenly spikes to 100% with no real reason, i cant link any particular app or process thats causing this, all of the cores on the processor appear to be coping with no faults.
The only thing i can think of thats causing this issue is either iv got a pending hardware failure on the board, or possibly bad blocks on the nand memory, however i cant see any simple way of determining this without rooting and using the likes of ODIN or other 3rd parties etc - linux commands etc.
I dont want to root it particularly if i can help it as i was thinking about selling it on to mazuma or the like and let them sort it out instead, but i think i might have to bite the bullet and try it.
Can anyone suggest anything that i might have missed?
Actually iv seen an existing thread which appears to match my issues, so iv installed wakelock on the phone for now which seems to be helping a bit, time will tell, however this isnt a solution but more of a work around, but im still thinking this could be a motherboard issue myself, however, as i think this phone is over 2 years old, i doubt samsung will replace the component, nor would they necessarily believe me if i turn around to them and say its the board that needs replacing!
