Green screen of death (rooted) - LG V20 Questions & Answers

I'm rooted on VS995, currently using AOKP ROM. Seems that any ROM I use, I get a green screen of death every 2 days on average. Pressing down volume reboots the phone and we're all good for a few days.
Anyone else see this?
What is a good way to get meaningful logs or meaningful data? I never know when it's going to crash and sometimes does overnight which kills my alarm.
Thanks!

Its a kernel issue. I've had it on various AOSP roms on the V20. Try using Werewolf Custom, that may help.

I had it on Werewolf Custom too. That is my current daily driver.
You know what is really odd is that I had the same problem with my rooted LG V10. I ended up setting it back to stock where it ran great (then I sold it). Rooting and LG are tough customers!

The last LG phone i had was the G3. Kernel panics all the time. The only devices, outside of Nexus products, that I owned that had no issues were HTC.

Happened twice tonight. AOSP, latest werewolf kernel. I duplicated the green screen but was literally installing a clean Ubuntu build on the laptop when it happened.

[Q] Freezing issues resolved with mod?

I'm now on my third G2. Sent the first two back in because they were having the freezing issue that's been documented here and on other forums that require a battery pull to get the phone back up. The second phone also had a dead pixel.
I have not yet had the issue with the latest phone, but have only been using it for a day and am not super optimistic given my experience with the first two. I'm still curious if the freezing is a hardware or software issue.
I'm wondering if anyone had this issue with their G2 and had it resolved by installing cyanogenmod or another mod. I have not tried rooting/modding yet as I knew I'd likely be returning the phones and didn't want to go through the work of having to undo it. It just dawned on me today that perhaps it's something tmobile has installed on the phone that is causing it to freeze. So I was thinking it might be possible that a non-tmobile mod might resolve it.
I had the issue on RC1 and haven't had it freeze since installing RC2. It would freeze while the screen was off and I had to pull the battery and let it boot up again.

Thanks for the reply. How long have you been running RC2?
Since it came out. On RC1 I had about 2~3 crashes within the first week of using it.

All of my problems were gone after the OTA update. It has been running like an absolute champ since.

I stopped having the reboots once I turned off the wifi sleep. If you live somewhere with lousy Tmobile coverage, but have wifi @ home, it helps a lot. Even helps battery life.

what kernel? And if you're going to ***** about problems with 2.3.3 you should run fully stock to make sure some customization is causing the issue.
Never once had a random reboot related to a call. Why do people tend to only pay attention to half of a bugfix and never specify whether their "problem" is related to it and then post it the completely wrong section about the problem without searching for the older threads relating to their issue?
I encountered this problem too, just 3 hours ago; the first after upgrading to 2.3.3 since Thursday.
Stock (but deodexed) 2.3.3, rooted, dalvik,cache-wiped.
EDIT: And oh, it's not a reboot bug -- it was a shutdown bug for me. Wasn't on a call, phone was just on stand by in my pocket, while my wife and I watched Voyage de la Vie. After the show, phone was dead, power button not working. I had to remove the batteries to jack it up again.
I guess I would be wiping my phone again, oh man that sucks.
But in the end, I still love my Nexus S.

People don't understand. They just see "reboot bug" and anytime they get a reboot it's "that bug".

My G2 (pure stock) rebooted once in a while. In fact I watched it happen while i was in a meeting there day before I got the nexus s. It must be the same bug!
nexus s has not reboot once, though ill give it time its only been three days.

On CM7 build 12 with netarchy 1.2.7... it rebooted once sitting on the desk doing nothing lol. Haven't had a reboot since but it's only been a day. Battery life seems pretty good but 3D performance took a hit on 2.3.3 =\

is this from benchmarks or are you seeing real world performance decrease? I am not trusting benchmarks as my g2 performed better in quadrant, yet real world the ns feels much faster.

Both. Benchmarks are lower and also when playing games like dungeon defenders its noticeably slower than before.

That's strange, the ns has a good gpu..

I'm not saying it's bad, I'm saying the performance is worse than when I was on a 2.3.2 CM7 with the SAME PHONE. Not sure what comparing GPU's has to do with this.
Anyway, just had a reboot while trying to do the pattern unlock to wake my phone. It booted with a little "Safe Mode" thing at the bottom left, never seen that before. Then shortly after that it promptly rebooted itself again and it's back to normal CM7, but all my widgets mysteriously vanished from my home screen... great.

True, that was just my impression switching phones. I suppose it was a stability/compatability play as I hope they wouldn't unknowingly release a build with an unknown gross performance deficiency in the display driver.

prior to 2.3.3 my phone rebooted while in stand by on a daily basis and just once while on a call. i haven't noticed it after 2.3.3, but i'm not holding my breath just yet. i hope it's fixed.

My phone is doing the exact same thing.
On 2.3.2, CM7 nightly 2.3.3, and stock 2.3.3.
Wiped or not. Rooted or not. Same damn reboot/shutoff.
It just reboot/shutoff with screen off, and hangs dead there sometimes with LED lights on. Have to remove battery to boot. Sometimes takes a dozen time battery removal to get it pass bootloader.
I am fed up. Now I am using wiped non-root 2.3.3 with a broken CMR, and still reboots!
I am going to flash the stock Recovery back and lock the bootloader before sending back to Samsung for replacement.
But seriously, what would you recommend as my next phone. I am thinking about Tbolt or Atrix.

It's not.
I have 2 Nexus S, both of them have spontaneously rebooted on 2.3.3.
It was much worse on 2.3.2, though.
Both are stock, not even rooted. Even most of the apps are different (my wife uses very few).

You do realize the "reboot" bug has nothing to do with just rebooting right? It has to do with rebooting while DURING a call. Also You're running CM7, so any random reboots is an issue with CM7 itself. It's still buggy as heck.
And ummm actually for me. Build 11/12 has been strong, not a single reboot. Used to have random soft-reboots, soft-reboot loops, and can't unwake the phone. All needing battery pulls. Haven't had a single random reboot with CM7 build 12.

Except that it's happening to way too many of us, NOT during a call. I call that a "reboot" bug.
My phones are stock.

Anyone with CM7 getting random reboots still?

Just wondering if you had random reboot issue and then it stopped after flashing cm7? Thanks

Have you flashed a different kernel? Or are you over clocked or undervolted? I was getting randome reboots because I was undervolting incorrectly. I am now running Faux's latest .2.0 1.3ghz kernel and have had no reboots.
I get them on rare occasions .... but I'm experimenting with UV ... not frequent enough for me to pinpoint an issue or to be annoyed by it. Last time occurred after after doing a system setting.
I dont get random reboots anymore, cm7 and last faux kernel at stock 1.0ghz fixed it.
I've been on CM7 for a week and no reboots.
been running it for 2 weeks or so. Had one minor glitch yesterday with my device when I locked the screen- she wouldnt wake back up and had to battery pull. Other than that, no issues. I am running Faux's 0.2.0 Stock CM kernel as well.
I had one reboot on my Atrix since running CM7. Compare that with several a week on the stock Motorola software. Using whatever kernel shipped with CM7. Overall, a great improvement!

It could be due to something not getting flashed right. Depending on what rom/fruitcake/etc is flashed, not all images are replaced. That's by design, because the good ol' fashioned SBF flashes EVERYTHING, which you really don't always need, and can be potentially dangerous. Assuming something got corrupted somewhere, or there's an older version of part "x" that doesn't like to play with the never version of part "y", that could cause a crash. You might want to look at a safe way to get a clean wipe, and then redoing CM7. I'm not suggesting SBFs or anything. But I'd check out samcripps' Fruit Cakes @ http://forum.xda-developers.com/showthread.php?t=1163009 though.

ICS/job ROMs without headset bug?

Sorry guys im new to the my touch comin from the g2 recently. Is anyone aware of what ROMs don't have the bug where the battery drain is high when headset is plugged in?
Thanks in advance
Sent from my Toasted Marshmallow using Tapatalk 2
From what I have found all ROMs based on 3.x kernel have this issue. Some even get very hot. The work-around I have found...is to use bluetooth headphones, however I also found that most do not allow GPS to work whilst bluetooth is on.
In the g2 ROMs the issue was cause by a camera driver... could this be the same case? I'm far from a dev but it was easy implemented by flinny in the g2 forums

i really hope they figure it out, i listen to music alot and battery dies in 1 hour with phone getting cooked. All the ICS/sense 4.x roms work perfectly though except minor lag. I wonder if their kernels could be used in jellybean because i once flashed elgins kernel on the oneV port and the heating issue appeared, reverted kernel it disappeared. Loved the PACman and CM10 but cant last 3hours with charge and superheated pockets

Same here. I get about 45 minutes of usage before the battery dies
I wonder if perhaps the camera can be frozen and have a 3rd party one in place...or is it the actual driver itself that causes the issue? (though why a camera driver would affect sound...)

Ya.. idk why it causes it but it was fixed in the g2 forums by a dev and a swear he said it was a camera driver. Basically keeps the device awake while plugged in.. hopefully a dev sees this and contacts flinny in The g2 forums. He had it fixed. Or maybe someone will port his jb build.. ....damn if only I was smarter

So I froze the camera, as I said I would try, I ran music for 2 hours (while plugged in) and surprisingly, the phone got warm but it did not get hot! I then unplugged it and ran it for 50 minutes, (up from 45), so the battery drain was also diminished but not very significantly. Still the phone only ran warm and not hot. So I think that the issue might be related in part to the camera.
On noice... ya like I said that's what a dev mentioned over in the g2 forum that got the other jb builds working too. Are any kernels (non 3.0) able to be flashed on jb without causing major issues?

Horrible battery life

https://imgur.com/a/uw1yr
I'm running Resurrection Remix on the latest build and have been having horrible battery life (about 2 hours sot) since quite a while now. I now charge like 2-3 times a day and overnight...
I recently did a clean wipe and reinstalled all my apps while only restoring Google authenticator and wifi passwords with titanium backup. I'm rooted with Magisk. I bought my Axon7 quite exactly one year ago. Have I fried my battery?

No, not really... I mean I can set a power profile, but that doesn't really do much.
I have to confirm that again, but if I turn on Airplane mode, my battery is a beast. I think there's some sort of drain coming from the kernel or something

You could try flashing a different modem for your model.
Maybe an app or two also keeping it awake and trying for a network? Not getting a deep sleep in doze.
Stock ROM has power manager and I suspect that is the only reason I get a day from mine.
If you're still suffering I suggest you go back to stock or reflash properly as in step by step and make sure nothing has gone wrong.

Where would I get that? I believe a friend helped me flash one a few weeks ago, but I don't remember where it was from. (I've had the issue before too, though)
I get this too. Absolutely horrible battery life. Well this started happening after I flashed the B32 bootstack and stock system to fix my camera issues. At first I thought it was the stock rom but I flashed candyrom and the llama sweet kernel EAS version and I still get it. I do think it's the phone signal but I'm not sure yet. I used to drop to 98% in about 10-20 minutes with WiFi on and screen on. Now I lose 10% in that time. I went from 98% (it doesn't even want to fill charge anymore but I think it's the kernel) to 92 in 10 minutes.

I feel you... I really hope it's just basically a software issue... If you have any solution, please, please update me and the others here - i just flashed the kernel that got recommended to me and I'll try if it makes things better. Otherwise I'll wait for Oreo, I guess...
I'm not even that sensible to bad battery life in phones because i always carry a powerbank, but if the phone barely makes it to work in the morning and I have to recharge it at work at 25% or so, it gets a little annoying ^^

True that...I don't believe it to be the battery. It could be software. I noticed that my battery usage spikes up to 1140+ mAh and stablizes at 460 mAh which is way too much. I remember only getting up to 430+ in worst cases and stabilizes at 200-300+
Here's what my battery usage looks like:

Fullstock is how I got into this mess i think, since this started happening as soon as I flashed B25 bootstack and stocksystem. But the new baseband, I'll try that and see how it goes. However that's B25, we're on B32 so hopefully someone posts the new modem. I have not tried flashing an older bootstack as I somehow doubt that will fix it. Granted, i noticed my battery life starting to wear while I was on an older bootstack while on DARK rom.
ediit: it seems i'm already running this modem version. https://imgur.com/a/8jeEh
