[G900F][RR7.0.2|Pie]Sudden issue with Custom Kernels - Galaxy S 5 Q&A, Help & Troubleshooting

Hello together,
I'm using official RR ROM 7.0.2 on my G900F, until recently with latest tuned kernel. I suddenly got some random freezes with reboots without knowing the reason. Then after some crashes it resulted in a bootloop, meaning that the RR bootscreen is loading forever (already tested for hours).
Flashing RR ROM again fixed the issue completely, but when I flash tuned kernel again I immediately end in bootloop. Flashing boot.img of RR ROM once again fixes the problem. Then I tried Intelli-Kernel and it boots, however the first unlock screen is very laggy, system ui takes long time to load after unlock (after that it works normal) and I get here and then sudden reboots. After some crashes/reboots I end up with bootloop with Intelli-Kernel.
Once again: flashing boot.img of RR fixes all the problems.
It's unlikely that the kernels itself are at fault, as they are working for many others and also worked for my device until recently.
So why am I unable to use custom kernels suddenly and how can I fix it?
I'm grateful for any hints you can give to pinpoint the reason. I already asked in the kernel Telegram group but sadly they weren't able to help me.
- I'm clearing dalvik/cache every time,
- tried TWRP repair feature for /data partition
- and as far as I can say I removed all remands of boeffla config app, but even if there are some they should load after system boot so obviously kernel settings aren't applied when I stuck on boot screen.
I don't overclock but for the same reason it shouldn't matter even if I do.
If possible, I would like to avoid a full wipe.
Thanks in advance.

Have you tried backing up your entire phone, wiping and installing RR, letting it boot etc before rebooting to recovery and installing a custom kernel again? If that fails, then either the version of RR you are using is incompatible, or you have some sort of hardware failure somewhere.

[Q] Nexus 7 boot problem-kernel/rom issue

Hey there! I was updating my version of Paranoid Android and my kernel and it seemed fine at first but It yield some odd problems. I went into Clockworkmod recovery and Flashed my rom and kernel I then proceeded to wipe my cache and dalvik cache. I have done this many times before on many devices. I encountered a problem when I rebooted for the second time, I got the Android is updating apps display and I continued to get it every time I booted. The device would also randomly turn off when the screen dimmmed. I proceeded to set out and fix it. Here are the steps I took and the problems it caused.
Flashed stock rom-would not boot properly
Flash RESET kernel-I messed up and though this was a real kernel, my problems escalated from here.
Flashed stock rom and recovery.
Flashed reset kernel and then real kernel-Still had problems.
Flashed stock rom
My problems from all this accumulated somewhat and I can barely boot into fastboot. I get weird static screens and weird white noise sounds. It does not always let me boot into android and will get to the google logo 1 out of ten tries.
These is really unnerving and I have no clues whats what.
Note: I am using Faux123's kernels and his reset kernel.
Thanks a lot for any help!!!

[Q] Phone will not start after first restart from a fresh flash

I have scoured the internet to find someone with the same issue as me, and I haven't found enough to fix the issue, so I'm placing a plea for help here. I have installed TWRP 2.6 recovery, and I am trying to flash OmniRom 4.4.2 nightlies. Originially I was trying to flash cyanogenmod 11, but I had this same problem. It appears to be any kit kat rom that causes the problem (I haven't tried flashing stock or any non-kitkat roms, but I was running on rooted stock before I tried to flash CM11). Anyways, When I flash I am wiping dalvik, cached, system, and data. Then flashing the rom, then flashing Paranoid android gapps. It will boot the first time fine. My phone will work just fine afterwards. However, if my battery dies or I restart, I will be unable to boot back into the rom and my phone becomes a soft brick. It will just stay stuck at the galaxy s 4 logo for as long as I leave it on. I have left it on for more than 30 minutes and there are no changes. I can't have my phone being just a dead battery away from being bricked, so I am asking for your help! Anything is much appreciated!
One other side note: I had my phone just lock up on me once in the middle of it running just fine. Afterwards it turned off on its own and tried to restart, but it resulted in the same issue. I don't know if this is related or just a bug in the rom.

Omni clearly states that it is an alpha, so you mileage may vary considerably.
Sounds kernel related. Have you tried just reflashing the kernel and seeing if it'll boot after that. Or trying a different kernel?
Thanks for the reply! I actually just fixed the problem on my own. I used Odin to flash a newer version of TWRP and then flashed omni, and it looks like everything is working just fine. I read a few people saying that they were having issues flashing kit kat roms with older versions of recovery, so I figured it was worth a shot.

Resurrection Remix ROM 6.8 Build running Kernel 6.2 - Bootloop Issue Zenfone 5

Hello, Newbie Here!
So I recently flashed the Resurrection Remix ROM Build 6.8 and Kernel 6.2.
The Build is rather stable and In my honest opinion better than CM12.1 which I was on previously.
So the normal functions of the phone are normal and I feel this is a much stable build. I use a ASUS Zenfone 5(ASUS_T00F)
But I face random reboots where the phone restarts itself and gets stuck at the boot. Only when i try to force reboot from the bootloop screen does the phone restart normally and even that takes three or four attempts. First I thought it was just getting used to the new Kernel then when this started occurring frequently I became more aware that this might just be a potential risk.
Today afternoon, My Phone was literally stuck at bootloop for 2 hours.... Only when I tried to do three-four manual forced reboots by pressing my power key and with each instance entering the TWRP mode and doing a dalvik and cache wipe only then was I able to boot up my phone normally.....It totally drained the battery though. I was at 78% and when my phone finally booted up I was shocked to see just 1% charge left.
Everytime this issue occurs...either the phone is completly stuck in bootloop or goes to the "Android is upgraing your apps" notification and then again comes back to the bootloop.
I have also done two fresh flashes before this as well so I know its got nothing to do with a dirty flash.
I then started googling for the same issue that other Zenfone 5 users might be experiencing but to my shock...No threads on it could be found with the issue that Im experiencing.
Pretty frustrated right now I have no clue what to do.
Donot want to go back to STOCK ROM..It sucks.
Please help Guys!
Hello.
You should try to format system and reinstall the rom + xposed. After that you can format data, cache, internal storage. I hope that it will help you.
And did you have this problem on CM12.1?

Phone crashing and shutting down randomly when not On charge

. For the past few days my phone has been crashing and turning off randomly, when the phone is off the charger. The screen just goes black and Shuts down. When I try to reboot the phone it will get upto the boot animation and then freeze and shutdown again. I have to connect my phone to a charger and then reboot, only then does it fully boot up. My battery is 100% btw.
What I have done so far is:
1) flashed the latest build of exodus
2) cleared dalvik and cache
3) flashed an earlier build (25/07) without flashing XPOSED and SUPERSU. However problem still present.
Can someone help please and tell me what other steps I can take. My phones important to me at the moment as I'm away in Turkey for an internship. It's a really strange problem I can't figure out what to do. Thanks alot
Did you try to go bacm for stock oneplus OS? Try to do a full recovery via the tool it will wipe root twrp back to stock. It may help.
Does it happens with other roms?
hi, i solved the problem by flashing stock oxygen. i tried flashing oxyslim and cyanogen however both of them still had the same problem. Anybody have a idea of why this might have happened? it was completely random, and if it was the kernel then it would have been solved when i flashed the other roms...strange

It could be that te ROMs u DL were corrupted. This happens, thats why is always good yo verify HASH from your dl ROM and HASH from the developers topic
So you haven't read up on the official CM13 thread about the latest unstable builds?

TWRP Randomly started freezing and crashing when attempting to wipe anything...

Hello,
I have an odd problem I need to iron out. . . Recently I installed the NeculaROM mostly without a hitch, however I was having issues not being able to make outgoing calls, so I wanted to switch back to my old Rom. Normally this wouldn't be an issue however when attempting to wipe anything on the phone, it starts vibrating and shuts off in TWRP. I can flash things fine still, back things up, yada yada. I tried reflashing TWRP, and that didn't help either.
So now I am stuck on this rom, and I can't do anything in TWRP. Is there any way to fix this? I can't seem to find much information on this particular issue. Any help would be great.
Thanks!
I believe this is caused by f2fs changes with rebasing this device to nougat.
Have you tried using the TWRP linked to the OP of the NucleaROM thread? You might have to format internal storage to get things working right again.
If that doesn't work out for you I'd recommend searching around more recent discussions in the TWRP thread and LineageOS thread. These issues with wiping and differences between unofficial TWRP, official TWRP, and what works with what ROM/firmware combinations have been covered in both.
Sorry I'm not more help on exactly what to do. I've just stuck with marshmallow firmware and custom roms based on it. I'm waiting for the dust to settle on this nougat rebase business.
Had same issue. I ended up just reflashing all the firmware images. Fixed my problem (for the most part.)
