CM12 and CM12.1 bug? - Nexus 5 Q&A, Help & Troubleshooting

I decided a few days ago to downgrade my phone from 5.1 version of android to CM12. Did so successfully by flashing 5.0 bootloader and radio, then CM12. As soon as it booted I noticed the processor or battery mode is stuck on power saver and will not switch. Yesterday I updated to the new 12.1 nightly and still same problem. Would like to be able to toggle to balanced or performance. Is this a known problem or does something cause the bug?

Clean flash. If it still happens then it may be a ROM/kernel issue, or just user error.

Clean installed, went as far as formatting /system. Problem still persists. What can I do to report this bug?

No point formatting /system since it does that in the flash script anyways.
Report it in the CM bug tracker if you are certain it doesn't work. I recall others having the same issue previously, maybe they just haven't fixed their profiles yet.

[Android 5.1] Random reboots.

Good afternoon gents!
This is the first time I post on this forum so I apologize in advance if I am not going to provide all the details regarding my problem. I'll try to be as explicit I can with my issue.
A couple of weeks ago I bought a LG Nexus 5, second hand. After one day of use the device started to randomly reboot. The odd thing is that the reboots seem to be "soft". After the device restarts there is no data loss, even the recent apps are still there. The reboots are as random as I can get, when browsing with Chrome, checking emails, or playing a game.
I tried several fixes, including costum kernels, costum ROMs and so. The problem persisted with the official KitKat 4.4.4 and Lollipop 5.0, 5.0.1 and 5.1.
Currently I am running stock Lollipop 5.1 with stock kernel and TWRP 2.8.5.2 recovery and the device is rooted.
Below I attached a screenshot with the device's current configuration and a text file with the kmsg log from the last reboot.
Faulty power button.
Reboot phone into bootloader/fastboot.
If it random reboots in the bootloader too, it's likely the power button.
Nope, I already tested this. The device reboots during use, either heavy or simply browsing the menu.

I noticed this in your Log
"<6>[ 0.514020] [email protected]: Power-off reason: Triggered from UVLO (Under Voltage Lock Out)"
Just curious, Are you undervolting?
I don't know exactly what undevolting implies. Could you give me more details please?

Lowering the voltage the CPU runs at, at certain frequencies.
I understand. No, I did no change any of the voltages. In that log that I posted up there the device is rooted and has TWRP 2.8.5.2 with stock lollipop 5.1 and stock kernel. Later yesterday evening i installed xtrasmooth rom with franco kernel and the phone only restarted in Here Maps from Nokia. I'll run more tests, but from this I draw the conclusion that it is a software problem, not a hardware one. Unfortunately I can't RMA the phone. Do you lads have any other opinions?

Try posting another log if it happens again.
I'm back with the latest ksmg log here. I searched for fixes all over the internet and nothing seemed to fix the problem. Restarts also occur in safe mode. Below is the latest last_kmsg.

This log shows a kernel panic.
My n5 reboot today without any reason
That was the only thing I understood from the log too. Do you have any idea what's the reason for these kernel panics and a possible way to fix them?
I experienced today three more random reboots. I attached down the logs. As an unexperienced users point of view all of them are produced by a "Unable to handle kernel paging request at virtual address" . Could anyone throw a look on them and give me a possible reason for these reboots and a possible fix? Thank you in advance

having the same problem. i'm running 5.1, but dont know if it's caused by that, cause i just got this phone as a refurbished one from google.
Good day lads!
I tried since the last post more possible fixes, and the only thing that showed some resuslt was downgrading to 4.4 bu the device still resarts exactly once a day. I am going to switch to another phone.

If you just recieved a new device and you have the possibility to RMA it, I suggest doing it. I went as far as page 30 on google searching possbile fixes and came up with no valid result.

Random Reboot on Lollipop 5.1

Hi, I've got some random reboots after upgrading on stock Lollipop 5.1 on my Nexus 5.
I've used Android 5.0.1 without any reboots or problem, but after upgrading on 5.1 I'm facing many random reboots when I switch from an app (like a game or Hangouts) using Recents or Home button from NavBar (it also happens randomly when I'm using my phone, like writing a message on Hangouts).
The reboots I'm talking about are not "soft" but "hard", because bootloader's logo (Google) appears and restarts my phone, so it is caused by Kernel Panic (as you'll see in my last_kmsg) and they occured on both stock and custom rom.
Here is a "last_kmsg" when it occured on stock Lollipop 5.1: http://pastebin.com/80dDgzae (attached too).

Flashed Android 5.0.1 and no random reboots (as I also said when i wrote my first post).
I don't know if the "question" is clear, but can you help me reading the "last_kmsg" which I attached in first post? Thanks
Same exact thing happening to me also.

The same is happening to me. And it looks like a hardware problem cuz when the phone reboots it keeping reboot until I keep pressing the power button while boots.
I have a bad experience about it. In my Nexus S when updates to Jelly Bean the same occurs until phone suddenly die. (I live in Brazil so, guess what? I have now a wonderful paper weight)
No luck with 5.1.1
You guys found any fix?
I was waiting for 5.1.1 update from Google (5.1.1 code is already available on AOSP and I tested it on Chroma), but unfortunately it didn't solve this problem: it keeps rebooting after a long daytime doing the same things I already wrote in first post. I'll wait for factory Google factory images, but I'm pretty sure it won't fix this.
P.S.: I tested Chroma on 5.0.2 bootloader and modem.
Anyone can read "last_kmg" I posted in first post? Any other has the same trouble?

I just flashed ElementalX kernel but no luck, random reboot happened on 5.1.1 too. By the way it was quite obvious because it happened already on 5.1 Google's factory image (stock kernel so)..
I have exactly the same issue with nexus 5 since upgrading to 5.1.0.
I went back to 5.0.1, which solved it for a few days, but now this happens with 5.0.1 as well.
also, before random reboots happen, the power button becomes extra sensitive, so one keypress causes the screen to turn on and off again, or to display the shutdown menu.
this does not happen when the phone is stable.

Same here.
LG Nexus 5 - Lollipop 5.1.1 LMY48B
Unlocked bootloader;
Rooted;
ClockWorkmod 6.0.4.5 (not flashed - just boot on image when used);
Wipe factory reset (in cwm). Flashed 5.1.1 image files (boot, radio, bootloader, system and cache).
Random reboots, and sometimes with apps optimizing.
I have the same problem with N5 since upgrading to 5.1.1 - never had any problems before. Doing it several times an hour now. Trying a cache clean next, after I wait for the optimising apps to finish yet again!
Hi all,
I had the same problem. Everything stock, up to datÄ™, no root. Phone was rebooting itself several times in a row.
Right now it seems that problem dissapeared. Reboots in my case was caused probably by application Autoguard Dash Cam Blackbox. After removal no reboots for 2 months and no memory leak.
cleared cache and it happened again within a minute...
Does seem to be linked to the power button
There's a long thread about this issue over at Google Groups. It's affecting a lot of users and not just Nexus 5 users. Some in the thread are 4 and 7 users having the same issue. Some have replaced the battery and it has resolved the issue, at least temporarily. Others, like myself, saw success in rooting and replacing the kernel or using a new ROM. Users who have downgraded to Kit Kat report the issue goes away, so despite the power button triggers, it seems to be a software issue. Anyone have any insight? It's getting feisty in Groups thread.

I have N5 kit kat 4.4.2 in Chrome watching videos randoms reboot its happens
This is happening to my fiance's N5. It happens when she's using it and also when it's not being used. When it reboots, it optimizes the apps and says the battery is at 0 when it was a full charge. Only way to turn it back on is to connect it to a charger. Frustrating.
FYI the update to 6.0 did not solve the restart problem. It's either hardware related, app related or a bug that's still in the OS.
I'm selling my Nexus because of this, has been happening for a few months now.
It's not software related, it has to do with the actual power button. Some people had success changing it out, soldering it etc., but I don't have that time or knowledge.
Google wouldn't help, as I'm out of warranty. So I guess it's goodbye Nexus. Really unfortunate given that the phone works fine, it's just a quality issue.. will have to re-evaluate buying another Nexus in the future.

CM13 / CM14.1 Mi4 screen flickering and very dark, also in TWRP, MIUI works fine

Hello,
I have a really weird:
I have a Mi4, TWRP 3.0.2.0 and had cm-13.0-20160905-NIGHTLY-cancro.zip installed.
Unfortunatly I am not entirely sure, when the problem exactly started, but the other day, my phone screen started flickering and was very dark, you could barely read something.
I tried disabling Live Display, Adaptive brightness, but it did not help. After I noticed, that on bootup the "Mi"-logo showed normal brightness, I could rule out a hardware problem. Interesting thing is, same thing happened in recovery. You can change the brightness there, but on max brightness, it is still barely readable and flickering.
I fully wiped my phone and installed latest MIUI global dev Rom. It works perfectly fine, no problems with the screen. After that I fully wiped again, because I prefer CM and wanted to try again. Screen is dark again, also flickering. Now I am back on MIUI, everything works fine, but still in TWRP the screen stays very dark.
What could this be? At first I thought about a Kernel problem, but the fact that the problem also exists in TWRP made me wonder.
I tried switching to CM14.1, but the problem still occurs randomely there, too.
I tried switching to latest CM recovery, same problem.
Thanks for your help.
Heeelp please!
For everyone following this: I managed to solve the problem by flashing this kernel after flashing CM: https://www.androidfilehost.com/?fid=24686681827314188
Little downside is; the kernel has a double-tap-to-wake-feature, which gives me some random unlocks in my pocket.

Bootloop with official LineageOS 14.1, but not with SultanROM

Dear ladies and gentlemen,
a couple of weeks ago I decided to switch from SultanROM (latest build from 30th April) to LineageOS 14.1 (nightly build from 5th June 2017). Due to some minor bugfixes I updated to the nightly build from 17th of July. My phone worked well, aside from 2-3 random reboots. But two days a go all of a sudden it hung up. I tried to get it up again with a hard reboot. After a while I realized I was in a bootloop. Of course I tried the first obvious steps to get rid of the bootloop:
Wipe cache (including ART/Dalvik cache)
Flashed the most recent nightly build (2017-07-31) + wipe cache
Factory reset
Updated TWRP from 3.0.2 to 3.1.1
But even then - no chance, I was still hanging in the bootloop. After a few more tries I flashed SultanROM and tried again. Surprise, surprise: it worked perfectly, the phone got almost immediately up!
I'd like to go back to LineageOS, but I don't have a clue how to avoid the bootloop when flashing it again. In the past I flashed other firmwares and images, too (i.e. the 44S and persist.img from this post: https://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061). Could this be a problem?
Any help would be appreciated!

Most of the outlined problems are about random reboots and a crashing camera (I read back to page 93). But my problem is: LineageOS 14.1 doesn't even start anymore - after wiping everything, flashing the newest nightly and doing a factory reset.

I flashed various builds with no success. What did seem to work is sultanized ROMs, I flashed Sultanized RR and it booted up fine and it was actually pretty good. Just a bit ago I went on a flashing adventure to go and flash AOSPA 7.2.1 but that ended up badly with a bootloop and a broken recovery. I was forced to download WugFresh's toolkit and fix the softbrick (lost all data in the process beware), I am currently on stock CM12.1 and I'm going to flash to AOSPA probably after the boot has finished up.

Don't think I'm going back to Lineage, RR for me is better (Sultanized or not version). For now I think I'm going to stay on AOSPA. If you try WugFresh's stock flashing tool I urge you to backup all your data.

Thanks for your advice. I already lost everything while trying to get back to LineageOS the last time. Fortunately I had up to date backups.
Have you flashed any ROMs or other stuff before that could cause the problems?
No, not really. I had this issue (meaning that I couldn't change to another non Sultan ROM) for a while now but chose to ignore it. Today I flashed multirom on top of Sultanized RR but I don't think that made any difference, when I flashed to AOSPA everything went South.

I originally suspected the firmware as well, turns out that probably wasn't the case, but I am now also now suspecting that the ROMs I tried to flash weren't f2fs compatible and it wasn't sultan's fault after all.

Issues with latest CM nightly

HI,
i've installed the latest nightly (cm-12.1-20160822-NIGHTLY-xt925) for the xt925 and gapps. It was running fine so far but after a while it starts crashing during boot or "optimizing apps" and it starts over again. This happens usually after installing updates from the playstore. My guess is that streetcomplete or mapillary might cause this issue (not sure the clock app crashed often too).
So my question is, has anyone else issues with the latest nightly and found a fix?
Are there any other ROMS available? I couldn't find a lineageos Rom.
I am able to reinstall and i think it will work again buts that no solution if i can't update apps.
I'm not sure which bootloader it currently uses. It has the cyanogenmod recovery installed and wiping Cache didn't resolve the issue.
Thx

For some reason all the official nightlies i have tried have this issue, some cant even make it past the setup screen. I guess something bad ended up in the sources.
Its not maintained anymore for our devices but one of the best CM12 builds in my experience was Mokee OS. You can run the builds for the Photon Q (xt897) just make sure its the old one- i recall having issues with the more recent builds.
Personally though i have moved on to the Nougat builds. I'm currently running the builds for the xt907 and they work fine with my xt926. The crDroid build seems to be the most stable - https://forum.xda-developers.com/dr.../crdroid-3-8-nougat-xt907-xt905-jbbl-t3697571 The only requirements are you must be running the JBBL and the TWRP version for the XT907 (its linked in the ROMs thread instructions). You also need to format your data and cache partitions as F2FS.
