Strange bootloops. - Nexus 6P Q&A, Help & Troubleshooting

So hey.
I'm facing a really weird issue with my phone. I currently use DU and it works perfectly, however whenever I install 'Ubermallow' or 'Omni ROM' or 'chroma' or even PN for that matter they all initially work perfectly. I go ahead and install AK and xposed it's all still fine, then I randomly restart my device. It starts bootlooping. So I think maybe it's substratum going haywire I remove the overlay, and it's still looping. I end up rm-rF'ing the vendor partition and reflash that to no avail. Now I'm thinking AK kernel is messing up, but it works fine on DU. Xposed could also be it but again I've used it for so long on DU and before that on PA. So if anyone has any advice or anything drop a comment. Thank you

Well typically if you get a bootloop, something isn't playing nice with the system[obviously].
In your case: I'm using Pure Nexus + Kylo Kernel + Substratum and no random reboots / bootlooping on a controlled reboot.
Suggestions:
AK Kernel - Make a profile and then back it up, make sure it is working - no screen glitches or ui crashes, and reboot. Bad kernel settings [undervolting, etc] can cause bootlooping. Once you verified there you can boot, move onto your theme.
Regarding substratum - I would go into the vendor folder, delete the entire overlay folder, reboot, then apply your theme - making sure the themes are compatible. If you experiecing per-app issues, go back and then individually disable its over. Once it is set, backup your theme and reboot. If you experience bootlooping here then you've narrowed it down to the theme. You can delete the overlay folder from TWRP.
As always, install the ROM via clean flash for the best results.

[Q] Help with CarbonRom/TWRP/RazrM?

Question:will someone help me?
I will begin by saying that I have no idea where the problem exists for my individual situation, and it would be great if I could get some help.
Background:
I used to run Dead Rage 1.2.
Now I have been back and fourth between Skrilax nightlies and Bytecode's cm10.1 with little to no hiccups.
Over time I began to notice a little lag(notification drawer, swiftkey, and basic ui elements).
Problem description:
Then I decided to try some other roms to fix my issues.
When I flash Carbon rom:
- It has no lock screen by default (and I have not been able to fix this in lockscreen settings)
- The home button does not work (neither in pie controls)
- the quick settings panel button in the notification drawer does not open the quick settings( nor can I access the quick settings any other way)
- the home screen apps are strangely and slightly above the software buttons
I saw someone with similar problems in the posts of carbon but it was resolved by a single reflash.
I also tried a relatively new rom called Revolt on droidrzr:
- I experienced similar issues with the home button
- I did not delve into the issues more because the issues were similar to carbon
Explained, further:
As explained above I have flashed without issue before.
I am under the impression that the way to flash is:
1. mount system
2. wipe system
3. repeat
4. reboot recovery
5. mount system
6. flash
I have tried every variation on this set of rules I think is possible for carbon. I initially had TWRP 2.3. I have flashed without rebooting recovery, without mounting system, with a factory reset on the previous rom, wiping cache and delvik as well. If I don't wipe the system I get weird crashes and the home button still doesn't work but it fixes other things like quick settings. Sometimes when I would wipe system, and not do a factory reset, and flash carbon all my apps from the Bytecode build persisted. This made me think it was a recovery problem.
Then I flashed TWRP 2.5. I have similarly tried everything with TWRP 2.5 and get the same results. I have tried 6/21, 6/23, 7/2, 7/4 carbon on both recoveries.
I have a backup of bytecode cm10.1 and I am running that currently.
If some one would help me troubleshoot or fix my problem, I would love to get carbon. And I would be very much appreciative.
If I am in the wrong place please point me.
I did not post in the carbon topic because I do not have more than 10 posts.
I know that people are not paid to help me so I respect when they do.
Also if you need screenshots, I can reflash carbon and take some shots too.

Marshmallow ROMs freeze and crash = Hardware Problem?

Hello everyone!
I have been experiencing a strange issue with almost all the Marshmallow ROMs currently in the development section. The Phone boots, Setup Wizard runs, and in between, the screen freezes/hangs and after 5-10 seconds the phone reboots. Again the setup wizard runs and even if i'm able to complete the wizard, the phone frequently hangs and then reboots.
I had been running Paranoid Android 5.1 ROM before flashing the Marshmallow ROM and this strange issue suddenly started. I have tried to flash stock rom and then flash twrp, then flash the ROM, even wiped everything several times. Still the same issue persists. This is really getting annoying as i have tried 3-4 different ROMs and 2 GApps and still the screen freezes and then phone reboots.
And this happens only on Marshmallow ROMs as i again have currently installed Chroma 5.1.1 ROM and its running smoothly. I am beginning to think of it to be a hardware issue. Can anyone help me solve this?

Flash Frank ROM, Flash Tuxi Gapps from Frank's OP, no one is having any issues now. Also don't forget to do a factory reset if you can even the Internal data.

I have done factory reset several times. Even flashed stock via fastboot multiple times. Done the exact same steps you mentioned. Its not only with Frank ROM actually, i tried another Marshmallow ROM and the same thing happened again.
How is it that Lollipop ROMs are running smooth and Marshmallow ROMs are crashing?

seems like it's Gapps/ ROM problem (with setup wizard)
this my only suggestions:
1. try to flash Frank's M without Gapps > reboot normaly
if this worked, then it's related to Gapps issue...
if it still remains, then
2. Flash ROM, Gapps, wipe, etc.
after that back to home of TWRP > Mount > Mount system > back > Advanced > File manager > go to /system/priv-app
search for folder name related to Setup wizard/ Google setup wizard (NOT GooglePartnerSetup) > delete it > reboot
3. fingercrossed it will bring you to home screen without any problem...
good luck then :fingers-crossed:

Thanks i'll try this out when i get back home. Although i did try flashing just the ROM to see if GApps were causing the issue. Without GApps, the phone booted to the homescreen, but then after 5-10 mins would reboot itself. I don't know may be it has got something to do with temperature? Because i've noticed that the phone becomes very hot when it first boots up on a new ROM(i know its normal for it to get hot). But when i used the phone on a Marshmallow ROM when the phone was NOT hot, it went on pretty well for 20-30 mins and then again rebooted.

Here's another update. I tried the new Chroma Marshmallow ROM and it too had the same issue. The phone hangs/freezes randomly and then reboots. After trying so many ROMs, i think the issue is with hardware itself. None other has reported this issue, nor could i find it anywhere else. I guess i can say that my(and only my) nexus 4 is not compatible with Marshmallow officially and unofficially.
I don't know what kernel Frank's uses but you could always try to flash an alternate kernel. I haven't taken the jump to Marshmallow yet, but it seems TaUrUs and hellsCore support M (I currently use hellsCore with stock L).

I'll try another kernel and ping back.
Probably lacked boot the system before you install GApps.

The FC of Setup Wizard is discussed in the ROM thread of Chroma.
You can try this because it is advised by the Dev of Chroma and supported by many others and I have succeeded with this.
Flash stock L and boot up.
Boot into TWRP (make sure you have the latest) and factory reset.
Flash Chroma 1/11/2015 and Bank's Gapps without boot/reboot in between and no wipe afterwards.
Reboot.

At least for Chroma, that is a wrong approach. No boot between ROM and Gapps flash.
Make sure you have permissions granted to all of the apps. I had similar issues, and had to do with Location and apps making calls to GPS. Would cause a reboot, and not just a force close. Try amending the Location settings as well. All else fails, capture a logcat.
Everyone thanks for your time!
I found the solution. bjb2's suggestion did the trick. I flashed TaUrUs-Mallow Kernel after Frank Marshmallow ROM and everything seems fine now. Have been running Marshmallow since a day without any issues. Still it's curious why the stock kernel gave such errors.
Thanks everyone again for your suggestions and help

LG G2 D02 CM 13 Problems

My boss rooted his LG G2-D02 and installing CM 12.1 in the process. Now, after knowing that CM 13 was already released, he downloaded a copy of it and immediately flashed it onto his phone. He got a problem with Gapps and DL-ed a problematic version which caused the notification,"Unfortunately, Setup Wizard has stopped" to pop up repeatedly. We had tried following a few advices from this website but to no avail.
1.) We already tried using Force Stop and Disable under Apps->(Show system apps)->Setup Wizard (CM). I had also tried giving it app permissions, but all app permissions were already available.
2.) The only option is to flash CM 12.1 back again but it can't be done. My boss set the default recovery app to Cyanogenmod's own recovery program, which had limited functions, so I can't
also use TWRP ATM.
3.) My boss also tried something on ADB but to no avail
4.) Factory reset didn't also solve the problems.
I'm almost running out of solutions... Perhaps, I can use a helping hand from brighter minds in this community.
TIA
I'm using cloudyg2 v3.3 because cm13 has got a lot of bug for example
-I can't proceeded to music
-systtem has stopped once a hour
-I can't close touching vibration
I can't remember now but cm13 has got really much bug (yeah my english is very bad,I know this)
Now system is stable and battery is very very good but still İ can't scretch to music

Specific apps missing after reboot (BasicPlus 2)

Hi,
I use BasicPlus 2 rom by t-shock (http://forum.xda-developers.com/s7-edge/development/rom-basicplus-1-t3402601).
When I reboot my device, specific apps are complety missing and I have to restore them with TB to go on.
This is reproducible with these certain apps, for example Swiftkey, Es Explorer and Google Calendar.
I had this issue before and I fixed it by deleting the 'Android' folder on my external microsd (128GB Samsung Evo Plus), since the missing apps always create an empty folder there. Now this seems not to be working anymore, therefore I'm asking for a permanent solution in this thread.
Unfortunatelly I'm not able to post in the rom's thread since my account is locked for the development section, but I hope I will get some help here.
Thanks!
Did you dirty flash?
If you did, I highly recommend clean wiping after every update to a custom ROM.

Yes I dirty flashed from 1.1.1 to 2.0, since this was supported by the developer and he provided a fix to have a stable rom.
I also tried a clean install, but for any reason battery life wasn't that good compared to the dirty flash from 1.1.1.
It seems that no one else has such an issue, that would mean no one else did a dirty flash from 1.1.1, otherwise there would be more reports!?
In the meanwhile I made a clean install in each case of 2.0 and 2.1, but the issue still exists. I also wiped all caches after rom install, but there is no change. All apps survive several restarts but all of a sudden some apps disappeared after restart. I will try now with 3.1 and Prometheus kernel, too bad I cannot post to the main thread of the rom, since the developer doesn't see this thread I think

(Please reply)Facing a strange problem while flashing miui Pro

Last few days I tried to use custom ROM. Volte doesn't work. I've given up on that issue now. Now problem is Miui pro.
After flashing it keeps showing boot logo ( I waited for more than 30 minutes) but the older version (7... Something) flashes without any problem.
How long should I wait to complete it's booting process( more than an hour??!!!!!)
P.s- device encryption is enabled [ but I don't think it's causing the problem cuz older version is doing fine]
http://miuiid.blogspot.in/p/rom.html?m=1
Download this and flash like normal rom.
First clear data, dv-cache, system,
Then flash this along with magisk
After flash don't clear dv-cache, not even after flashing magisk and dont change anythink in the system partition untill first boot u can also flash the magisk modules straight ahead.
This is miui id best, u get paid themes free, also volte working and it does have split screen.
Note:- don't forget to flash magisk, don't clear cache after flashing the rom and i mean anytime don't do it it will take a lot of time then.
First boot will take 15 min, dont wait for it once it gets past the boot logo and enters the bootanimation wait for 2 min then again do force reboot by long pressing the power button, do it one more time this time wait for 5 min if it opens then good or again reboot. This time it will happen.
The rom is stable and totally worth the trouble.
This process is just to reduce the first booting time.
Thanks ?

Im running Miui 9.2 global stable 9.2.2.0
Can i do dirty install? I dont wanna lose apps data
Im using stock miui global stable 9.2.2. Android 6.0
If i wanna install miui id, do i need to wipe all , as in format my handset. Or is it ok to just wipe system, cache dv? I dont wanna lose my apps data
@Trovies hi,
Just do titanium or swiftbackup search the apk in google, and u can do dirty flash but i will not recommend it.

very well explained. As per habit I was clearing both dv cache and cache and due to this rom was taking too much time to boot. But after reading your post I have made clear pretty much everything. This is the best MIUI rom I have ever used. Performance, battery life, smoothness everything is spot on. I just wish it would had double tap to wake feature and recent apps menu would had icon mode option. Audio through earphones is also low. other than that its fantastic rom.

yup I'm not noob and doing exactly as you are saying but still I'm struggling with this rom
1st attempt wipe dalvik, system, data cache - flashed rom - flashed settings zip - flashed magisk - tried to flash magisk modules (failed) - reboot without any wipe - rom didn't boot
2nd attempt - clean installed with only rom and settings zip - booted normally - went to bootloader again installed magisk - reboot system - went in bootloader again - flashed app systemizer module- rebooted successfully - went to magisk manager and added module youtube advanced - reboot stuck on mi logo
3rd attempt - reinstalled clean as described in 2nd attempt till the setup of app sytemizer on reboot - went to app systemizer module and ticked gps app- module asked to reboot boooooom stuck on mi logo
Everything I wrote above is my common practice with every miui rom but I don't know why It is not working with this rom. anyways thanks for your help I am moving to global stable as I can't live without these modules. n sorry for bad english

Ya i know modules can be a pain in the ass only one suggestion when ever after flashing a module if its stuck in the bootloop then just use magisk Uninstaller then again install Magisk or use magisk for recovery to remove the particular module which is causing boot loop also use root youtube valence and use universal installer it will not cause bootloop. Also use minimal module only what you need. Ok then. Also do as u discreet i am fine in this rom. And its great. ?
See my modules
I too use YouTube vanced.
Man u got to find solutions not give up and change only after a few attempts. U know how many times i got bootloop because of this rom and it's compatibility issues with the modules. After many attempts i got it. Now its the best custom miui rom ever also the dev is constant and hops to bring miui 10. Also if u have used this rom only for a few hours u can realize the difference.

yup there is no doubt this is best custom miui rom out there. But this bootloop and boot time driving me nuts. I wonder why all this problems are popping up though the rom is based on official firmware and I've never faced such problem with official roms. I will give it a try again after two days. I just hope that time it will go smooth.
