[Q] MHL causes reboot (Boot Loop) - Samsung Galaxy Nexus

Issue reported here, please star if your device is similarly afflicted.
I dont know if things have just gotten out of hand (excessive modding) or if it is a hardware problem, but my gnex reboots and boot loops with my MHL adapter plugged.
I have gotten my kernel messages from before the reboot.
It seems that according the TI technical reference manual for the OMAP 4460 that my phone rebooted due to mpu watchdog timer event and it was a warm reset. (PRM_RSTST=0x10)
The mpu watchdog timer indicates that the system considered itself stuck and so made a hasty and determined decision to start all over again.
The warm reset flags reveals that software initiated the reset.
This is the way I take it: so either my Processor has seen better days and has grown to old and decrepit to do what it once did, MHL, or the way the new jellybean stock kernel in dealing with MHL is taking entirely too long. Seeing as how this isn't a widespread issue, though, I have seen others with this problem, I don't think the kernel is the cause really. But, I hope it is software related.
Will someone please help me here?
Is there a better place to ask this question?
I would appreciate someone with a working phone on jb 4.1.1 plugging in their MHL, rebooting their phone and then posting their /proc/last_kmsg file (requires root). So, I can see what should be happening and determine any differences.

I changed from stock jb 4.1.1 to bigxies deodexed and my mhl now works, if that helps anyone.

Any luck figuring out why bigxies deodexed rom works and stock doesn't?
It has had me stumped for weeks.

Not really,
I looked at the kernel logs between stock and bigxie and there was no real difference. Stock just rebooted, where bigxie kept going. The stock set some flags that indicated a software reboot due to a hang (watchdog timer).
I guess that maybe some apk or odex in the stock isn't aligned right, or compression is corrupt or something and when bigxie de-odexed he was able to fix it.
Plus the bigxie update is the OTA, not the factory image, so maybe there is some difference, though technically there shouldn't be.
There is definitely a difference in size and CRC between the two, see here.

Same problem here, reported.

I just want to say that using paranoid android fixes this issue at least on the current version 2.17 as well. I don't know why it fixed it. But i know of no other cyanogen mod based rom that works for affected phones.

Random Extreme Lag on VZW GNex

So here's what I've discovered.
As of now, on stock 4.1.1, the phone runs smooth when audio is screwed up. The moment touch sounds work again (or the moment I install SoundAbout to fix it) it starts lagging like crazy. Is this a hardware thing? After switching roms, kernels, versions of Android, flashing stock and locking the bootloader nothing has worked.
_________________________________________________________________________________________________________
So I'm having this strange issue that I don't really see mentioned previously (based on my multiple searches)
My phone was running fine until I flashed Paranoid Android (The last Jellybean 4.1 Release). On this ROM i was getting some insane lag, sluggish performance. I'd swipe on the home screen and get a huge delay or the phone would read it as a long touch and bring up the wallpapers option. Opening folders and the app drawer had some serious slow downs. It was a real mess.
I assumed the phone just didn't play well with the ROM so I flashed over to Bugless Beast. The odd thing is that the problems persisted. I would get just as horrible performance and the same sluggish visual effects and stuff. Specifically I remember even the audio slowing down and being choppy (touch sounds) until they automatically disabled themselves and the ROM ran smooth for a bit but returned to the sluggishness again.
So last night I restored to stock flashing the stock image and relocking the bootloader. Rooted, unlocked, flashed recovery again and loaded up Bugless Beast and the issue is still happening. Even got my first random reboot on Bugless Beast today after it slowed down really bad. Now I've noticed that when touch sounds disable themselves so does media audio (while the ringer and notification sounds still work). This is pretty much why I'm convinced it's a software problem and not a hardware one.
Basically I just wanted to know if anyone's experienced something similar and found a way to fix it? Probably going to reflash to stock tonight
EDIT: Well it seems like the audio thing might be a hardware issue. SoundAbout fixed that but I don't see how my audio jack could have been damaged in between flashes.
EDIT 2: Current State:
- I tried flashing just the system img (multiple times) and the lag returned
- I just flashed a 4.2.1 ROM just to see what happened. Touch sounds are back which means my headphone jack fixed itself. Still EXTREMELY slow.
- And just like that headphone jack screwed AGAIN but no more lag? Any reason for these two things to be related?
Bump. Any help? Still happening, though not as common, when I flashed stock
Could it be a hardware problem? Though it would be odd for a hardware issue to show up after flashing a rom. How long have you had the phone before the issues started?
Have you tried the official 4.1.1 image?
If so, do problems go away?
If you are using ports you have to expect bugs.
Let us know

Try flashing just the system.img a few times in fast boot with a reboot boot loader between. I was having slow boot up and random performance issues on full stock until I flashed that partition with the stock image (3 Times to be precise). I no longer have the 5 minute wait for the Google logo to disappear, and overall much snappier. Apparently something was leftover from previous restores/downloaded OTA updates.

I'd suggest you stop messing around with multiple ROMs and start trying different kernels. Kernels will impact performance much more than any specific ROM will. Try either an updated version of leanKernel (assuming your sig is accurate) or a different kernel all together. Others have had luck with franco, trinity, etc, etc.
Had the same problem on my GSM GNex yesterday. Flashed a ROM combination (Xylon 4.2.1 + Lean Kernel 5.0) and had this lag.. everything would lag and FC.. tried a full wipe as well but didnt work..
Changed to another AOSP Rom (UDK 4.2.1 with linaro kernel) and its fine now..
Oh and i also changed recovery from 6.0.1.5 non-touch(that i flashed yesterday) to CWM 6.0.1.9 touch..
Not sure if this helps but thats what worked for me.. I suggest going back to a ROM that worked for you in the past.. and also try formatting your SD card and run the phone without putting back your data for a while..
@rlb81 - Starting to think it might be a hardware one but at this point I'm not sure of anything. Only had the device 3 months.
@tincbtrar - Yeah I flashed the official 4.1.1 image and the problems are still there. Ridiculously sluggish and the audio problems. In fact, on stock 4.1.1 I just had this issue where I'd turn the screen off, the animation would be really slow, and then I'd get a black screen and wouldn't be able to wake it up. Did a battery pull to boot it again and the same exact issue the second time it turned on.
@Winesnob - I'll be sure to give this a try. Thanks so much! This is a really odd issue and I've never experienced it on any of my previous android devices (Fascinate, Incredible, Thunderbolt, even the old HTC Vogue)
@Cilraaz - Currently just trying to get stock running properly so everything is locked right now. Can't remember but I'm pretty sure I tried the newer lean kernel when I flashed back to bugless.
@technogravy - Kinda the same response I have for Cilraaz here. Ideally I'd like to get stock running properly so that I can be sure there isn't something horribly messed up with my phone but I'll be sure to give both of your suggestions a try if things don't seem to work with stock.
Thanks so much to all of you guys. If you have any other input it'd be greatly appreciated.
+1 on try different kernels, my phone seems to love lean kernel. I switched to tiny kernel for a few days and every so often, a simple task like opening tapatalk would take up to 30 seconds, and everything would become unresponsive. Nothing but smoothness on lean, give some different kernels a try.

I tried Winesnob's method and I THOUGHT it worked. Was running smooth for a good amount of time and just now back to the really choppy mess it was before. In fact it just got frozen on the lock screen and went to a black screen again.
This is killing me. The headphone jack thing seems to be a hardware issue anyway so I emailed Wirefly about getting a replacement. I feel like they'll avoid that though and I'll be left with this.
Gonna try some other things tonight. Wish me luck
EDIT: The thing gets so choppy that notification sound get choppy and crackle. This is insane. I'm fully stock minus the unlocked bootloader right now
EDIT2: Flashed stock image and touch sounds came back. This is getting really weird. Lag is still here though. Really bad lag
Bumping again now that I've sort of pinpointed the issue. Lags with touch sounds enabled and headphone jack works / soundabout installed with touch sounds on.
Currently the phone's headphone jack is screwed up, I installed soundabout, disabled touch sound and no lag.
Over in the dinc2 forums a lot of people are having the same issue when going from vipers sense rom back to aosp. I know that's not the case here but they found it was due to a new lib partition that was introduced in jb. Again, not sure if I'm 100% on this, but it does sound like a bad wipe and something is getting left from previous roms

Ahh thanks for the heads up
Would it be wise for me to try going back to the ROM that started the problem? Maybe that'll do *something?
Again, from what I saw, everyone had some luck going back to the rom that caused the problem.
There's a tool in the developer thread called "super duper wipe" that seems to have fixed the lag for ones having the issue. I'm not sure how it works, but If you can take it apart and look at the zip, it may point someone in the right direction.

I took a look at that super duper wipe script...looks interesting but not necessary on our phone.
Im starting to think you may have a hardware issue if you cant flash stock images and get everything back to normal. Maybe a relock and then unlock?
i just did this cause I had a SIM card issue...and naturally it wiped my data completely.

turns out my lag problems weren't gone completely until i wiped /System before flash.. Alot of ROM's out there have a /system wipe script, but the one causing my FC's and lag didn't, so it was installing the new system files on top of the old ones and possibly causing a conflict.
it could the same for you
Yeah I've recently tried unlocking again, formatting system before a ROM flash and I still get lag. Now it's more that it will last a day without the lag and just magically come back the next day. Headphone/speaker issues still exist. Wirefly completely ignored my first email so I sent them another one. Hoping for the best.
Completely lost on what this could be
anyone see this thread?

I have random lag on my vzw nexus and i think its io related and nothing to do with the kernel.

I'll check out that app but like I've mentioned. Lag seems to be coming from sound. After installing soundabout to get the speaker working again I get some nasty lag. Disable touch sounds and I have no lag. Disable the sound effects on twitter - no issues with the app. WireFly said I'm still under manufacturer warranty through my carrier and it sounds like I should be covered. If Verizon tries anything to get around that they'll be willing to do a three way call to make sure I get the replacement. I'll probably end up with a refurb but hopefully it'll beat this stupid issue.
Just stopping in to say thanks to everyone that tried to fix the issue but Verizon is sending out my replacement device today and I'll be sending this one with the faulty headphone jack back.
Problem solved!

[Q] Screen issue, software or hardware?

I don't know how to put this but not so recently I found out that my galaxy nexus' screen behave strangely after reboot. It's like a distortion for about 1ms (I guess). It's just a glimpse of distortion. Happen after bootanimation (right/exactly when home screen comes up) or just before bootanimation ends. It happens too when the battery is about to die (3 or 4% left, the warning pops up and the background is distorted but the pop up message not).
anyone has any experience as such above?
is this software related issue or hardware related issue?
any suggestion, explanation, help, or anything else would be highly appreciated.
thank you.
ps: bought my galaxy nexus 3 months ago, had zero experience prior buying my galaxy nexus, had experience of wiping system but could not able to flash stock rom via cwm (at that moment not knowing that cwm can only flash flashable zip not tgz or tar), right now running custom rom xylon 011 JB 4.2.1.
It used to happen to me when I was running cyanogen mod 10 the same way you described. Went back to stock and haven't seen that again.
Wow, thank you very much for confirming this. I forgot to put additional info that I had run CM10 too and had same kind of behavior.
So I guess that is software issue rather than hardware, rite?
Anyone else having this issue?

[Q] Clock Resets on Reboot

Defecting from the iPhone world to get an S3, I'm not sure if this is an issue or just standard behavior but when my phone is rebooted when it doesn't have a cell connection, the phone's clock gets reset to Epoch time (1970). It's actually not back to 0 Epoch but instead seems to be in May (or other dates) of 1970.
On previous phones that I've had, the device has been able to keep track of time through a reboot but my S3 seems to need to sync its clock with the cell system in order to have an accurate clock. Is this the case for all S3s or does my phone have some sort of defect when it comes to clock persistence?
This is especially noticeable if I put the phone into airplane mode and then reboot or if I reboot into recovery mode. Because of this, my nandroid backups are all time stamped in 1970.
I've encountered this problem in stock Touchwiz and in CM10 and I'm curious if it's also been related to other strange clock behavior that i've seen such as the on-screen clock failing to update for 10s of minutes at a time or inconsistent timing for my lock screen timing.
I made a support call to Samsung about this and was unable to get them to understand what I was seeing at all.
While I have never seen this is the System itself while running, regardless whether I'm connected to Mobile Data or WiFi, or even after an Airplane mode reboot, which I have to do quite often to restore data on my 4.2 ROM. It is something we are all plagued with in our recoveries. All Nandroids are stamped incorrectly. I'd recommend TWRP if you'd like to name your backups over CWM which only stores your Nandroid as an incorrect date.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Thanks for the feedback! It sounds like the nandroid timestamps are common but the fact that my phone's clock isn't persistent across reboots until it connects with a cell tower (or some other NTP server, maybe) isn't common.
It seems like it is probably some sort of hardware defect on my phone... I assume that there is a small battery or that phones use a trickle of power from the standard battery to remember the time and keep the clock ticking while powered down but my phone isn't doing that for some reason...
Does anyone have any tips for this, even if it's just to try to get some warranty service. I was hoping to not have to flash back to TW and unroot but I would rather have a fully functioning phone even in this minor way.
Thanks!

this happened to me once in a version of cm10. I simply updated cm10 and the problem disappeared. If these are similar problems then I think its ROM related. Did you do anything to your touchwiz ROM?

I'be had this issue with both stock and rooted TW (and a few of the July/August TW updates) and CM10, both nightlies and 10.0.0 stable. It doesn't seem like it's ROM related based on my observations so far...

[Q] Random reboots and lock ups (memory leak?)

Hey all,
I've had this issue with everything but the stock rom. After a certain amount of time the phone either locks up to where I have to pop the battery, or will graphic glitch on the screen for a second and then auto reboot. Happens maybe 2-4 times a day depending on the day.
I've done a full wipe and full factory reset. I've been modding phones for ages and this is the first time I've encountered this issue. Everything else seems to run completely fine.
I'm running resurrection rom, but it's done this on several other roms I've tried. However all roms are AOKP/AOSP based if that's relevant.
If there is anymore information I can offer please don't hesitate to ask. I searched the forums and couldn't seem to find anyone else really talking about this. It can be a giant headache so hopefully I can get it sorted.

If this has just started recently in would say it is indeed apart of the cm base, and related to kernel issue. Since the kernel devs are using cm and their kernel base most ROMs kernels have the same base, which means in a round about way they may react the same way on your device. To me, you said graphic glitch, then reboot. I would bump up your voltage little by little and see if it stops, I also would change govs in the kernel.. I'm assuming it happens on any cm kernels you've tried? Yank555 has an awesome cm kernel I would highly recommend, or even imoseyon always has a solid stable cm kernel as well.
How are you transferring the firmware? The heavy cable with the heavy plug? If so, it might have damaged your device's USB port and is causing intermittent disconnections which are corrupting the data as it is transferred. Try a lightweight cable and make sure it is firmly seated, then don't let it move during the transfer.
If this solves it then maybe look into replacement due to faulty design.
Frank
It is happening on all roms, however the only custom roms I've tried are CM based. I'll take a look at these other kernels and see if that resolves. Thanks for the help and idea's so far guys.
I've been having the same issues. Hellish reboots though. 10+ a day... Keep me posted. Thanks

Screen Glitches,Stock Rooted S3.

I've been getting these glitches/artifacts/tearing on any 4.4+ rom on my T-mobile S3.
It's like the status bar will glitch down to the bottom of the screen.
I'm currently on a 4.3 stock rom (ENC2), It's been rooted with the samsung toolkit and has knox disabled (at least according to the app).
I've tried most current d2lte roms, PA, spirit, ACIP...ect.) and they all have it.
I know for a fact I'm missing something. I just can't remember what it is for the life of me. I know it has something to do with the bootloader/binary. I seem to remember when 4.4.1 came out there was something with the bootloader we had to do and no matter what I search nothing is coming up with the correct solution.
I'm hoping someone could tell me what i'm missing because it seems painfully obvious and I'm missing it, . I really don't enjoy using TW.
We don't ever mess with the bootloader or other parts of the base firmware, so maybe you're thinking of a different device?
When did it start? What was the last thing you did (flash)? Tbh, to me it sounds like a hardware problem. Maybe a connector got loosened, or some moisture/water damage, or even heat damage could cause what you are describing. Especially if its happening on every ROM.
Flash the stock NC2 firmware via Odin and factory reset. If it still happens after that its almost certainly hardware related.

Does it also happen with touchwiz?
So. I ran the knox removal thing from the samsung toolkit and now I don't see them on the latest CM nightly.
I have to test a few other roms but I don't know, it's somehow fixed, thank you for the responses.
Glad to hear it. Be careful with the toolkit though. It is not supported and has bricked devices.

After giving it a few days the issue came back.
I've tested this on a stock nc2 touchwiz as well as your (doc) latest likewise release with no issues with the screen or anything.
For the non touchwiz I tried aicp latest 4.4.4, the latest cm11, the latest aospa weekly and a 4.3 AOKP release (milestone2).
The glitch issue wasnt in the cm release for a day or so then showed up, all others showed up instantly.
I also emergency recovered via kies. Then rerooted. I'm also using the latest twrp
Here is a logcat of the ROM I'm currently on, the 4.3 AOKP. I wish I had more of an understanding of logcats so i knew if I posted the right section.
http://pastebin.com/UyZFHriB
I was curious so I booted up a nandroid of aicp and then restored a backup of the boot from likewise. Results were minimal glitching but no connectivity at all. APNs didn't load and WiFi is broken. I'll post a video shortly of the screen.
The only thing that jumps out on that logcat is where you have this kind repeated several times in a row:
09-18 13:35:38.752 W/ActivityManager( *761): Permission denied: checkComponentPermission() owningUid=10060
But I honestly don't know what its referring to. But I will say that since it appears to be happening on every rom, even stock, it sounds more like a hardware issue. Display problems usually are to begin with, but almost any problem that persists across multiple ROMs and wipes can usually be blamed on a hardware malfunction.
Watch a disassembly video on youtube, then open it up and reseat all connectors. (Don't mess with the antenna. Its fragile and not related to the issue at hand.)

That's the odd thing, On both 4.3 and 4.4.2 versions of touchwiz I don't get the glitching. Only on AOSP based roms. I could just go stick with a touchwiz based rom and be done with it but my personal preference is not using touchwiz. I'm just confused as to what is actually causing this.
I'm guessing it has to have something to do with the bootloader and baseband.
I think i did forget to mention this is a "refurbished" warranty replacement, i regret that I don't recall which specific version it had as stock, I'd guess it has to be enc2?
Here is a poor quality video to show whats happening, on the home screen you see the glitching where the status bar glitches down to the bottom. I tried to get it to do what it sometimes does in both the MLB app as well as the reddit app but it decided not to be as noticeable this time.
http://youtu.be/ZsZL1Okio-A (sorry about the added music )
Just a side question, I couldn't seem to find a definitive answer, but was it ok to downgrade within the 4.3 bootloaders? I thought I remember reading that as long as you don't go from 4.3 to 4.1.2 it was fine.
Soryy I misunderstood before about it happening on stock. Have you tried any different kernels? I'd suspect that before bootloader. But since it's a refurb, there's just no telling for sure.
Once on 4.3 you cannot downgrade your firmware at all. You can flash older roms, but that's it.
