Best Custom Kernel for OOS 3.6.1 Stock Rom? - OnePlus 2 Q&A, Help & Troubleshooting

Here it is nearly midway through 2018...
I'm wondering a few things re custom kernels and the OOS 3.6.1 stock rom for the OP2.
1. Is there such a thing?
2. Does flashing a custom kernel (if one exists) for stock rom going to prevent voLTE and wifi calling from working on my TMobile provider?
Thanks for any help on this.

1. Sure, boeffla kernel with right settings is best for stock oos.
2. No idea, try it and report back (if you make a backup before, you can just restore it if it doesn't work)

Switch Back to the oldest stock rom

I'm done flashing roms. Lotta awesomeness but lotta bugs too. Currently im on ASOP Extended ROM 7.1.1 with TWRP (Hybrid) 3.0.2 and I want to go back. Way back, to lollipop or something. Where everything is stable and it works. Somewhere oxygen OS.
1)So would the method be a twrp flash of official firmware ?
2) I want to retain superuser priviledge and TWRP Hybrid. How do I do that after flashing official stuff since the firmware resets everything to original ?
3) I'm just looking for battery life. Would you suggest reverting to oxygen os lollipop or marshmallow ? ( NO I DON'T NEED VOLTE PLEASE SPARE ME. I JUST NEED 2 SIMS TO WORK.) (got a better rom ? suggest !)
Thanks IN ADVANCE XDA ! You've been great !

Custom roms without magisk

Hello, could someone explain me why magisk is necessary for custom roms for our device? When bootloader boots custom kernel it should boot rest of the system without any problems but it bootloops even before bootanimation
I also need custom ROM without Magisk. Is any Oreo custom ROM supports SuperSU?
RR-O ROM+Gapps goes to bootloop without Magisk and RR-O ROM+(Gapps)+SuperSU goes to Bootloader mode.
RR-O ROM+Gapps+Velocity Kernel boots & works, but RR-O ROM+Gapps+Velocity Kernel+SuperSU goes to Bootloader mode.
So anyone can please help for any Oreo custom ROM + Gapps + any rooting app (SuperSU, Lineage addonSU, phh's SuperUser).

Have you figured it out yet? If not here, we go...
A Custom ROM is to give you 100% control, it's the point, and to have 100% control, the phone needs to be rooted to access the system.
In Linux, 'Root' means, what the Admin is in Windows...
Kind of pointless to install a custom rom, with limited control, of course you can root a stock rom too.

Not necessarily. Custom roms may have up to date security patches vs out of date stock roms on older phones. And custom roms may have extra functionality especially on bare bones stock rom like the MiA1.

Yes of course all the 'Bells & Whistles' I didn't mention... But that's not the reason for rooting, which is what the OP asked...
Anyhow Custom ROMS give us many things, but it's about being in Control...

Installing custom rom after pie update

I'm currently on stock pie Jan patch, and I want to install a custom rom instead because I'm fed up with stock bugs. I'm looking forward to install pixys os, but I have a question. Are there any additional steps to install a custom rom? I don't want my phone to be bricked and lose my IMEI.
I have flashed LOS 16 without problems after Pie update.
You can flash the custom ROM without any big issues. Not sure about VoLTE though, if it is something you are concerned about.
Make a low level backup so you can recover in case something goes wrong

No fingerprint option in Security options in settings!

I was using Xtended Custom ROM (Oreo) with a rooted device and then i was just trying to unroot the phone and flashing Stock ROM but it didnt worked so i rolled back to Custom ROM and then my fingerprint sensors are not getting detected in any Oreo ROM.. please help!
If you really want to stay on an Oreo custom rom, you have to downgrade to stock nougat first. Easiest way to do that is use the latest nougat twrp flashable stock rom
https://forum.xda-developers.com/g5-plus/development/twrp-flashable-stock-builds-t3813351
Other option is to just go to a pie custom rom.
Edit - just remembered the is another thing you can flash that will just get back the fingerprint, but if you use NFC that won't be fixed. Maybe someone else has the link.
I got my fingerprint sensor back but lost VolTe now!

I got my fingerprint sensor back by flashing "potter-twrp-flashable-NPNS25.137-92-14-a" image but lost Volte support! I am currently using PixelExperience Custom ROM! Oreo based! I am gonna try shifting to a new custom ROM to see if i can get Volte working! If any suggestions please let me know!
If u had nougat and the u flashed PE 9.0 then volte will have issues. PE moved to oreo base long time back. Its better u flash stock oreo first and then move to any Pie Rom. There are some guides around to get volte back might wanna look around. Did you not make a backup of the stock image?

Did you boot into stock nougat before flashing the custom Oreo rom? If not, it is probably necessary. (When you had -a at the end of that filename, I assume you mean aroma? If so, then that one applies a fix to your persist which is needed going back to stock nougat, so that's all good.)
If you did, then it may just be a case of needing to go onto stock Oreo then a pie custom rom. Some things about the stock nougat just don't work properly after being on Oreo...

Ok, so you flashed some persist file? Was it my persist fix zip, or someone else's persist backup, in which case you're kinda screwed.

Try clearing cache within twrp. You shouldn't take any OTAs from the twrp flashable. If it was the OTA for Oreo, then might be easier to do a wipe, as I can't remember where the OTA gets saved.
I'm assuming that your device is trying to go to recovery all the time as it knows the OTA is there to be installed.
Worst case, total clean flash and install again.

Two basic rules:
- Make a backup. Every time before you flash anything. Every time.
- You only can apply and install OTA updates when on a signed and unmodified fastboot firmware.
Twrp flashable ROMs have a lot of advantages but they are not unmodified.
Agree with @NZedPred: Make a full wipe and install
a) a fastboot firmware if you need to take OTA updates, these are found here:
https://mirrors.lolinet.com/firmware/moto/potter/official/RETAIL/
b) a twrp flashable ROM if you won't take OTA updates, these are found here: https://forum.xda-developers.com/g5...flashable-stock-builds-coming-t3830482/page68
I have this same problem. I'm currently on stock Oreo and I'm not getting fingerprint option since I flashed PE 9.0. someone help.

Oreo ROMs that can be flashed over stock Oreo

Are there any custom Oreo based ROMs that can be flashed directly over stock Oreo without issues like missing fingerprint functionality?
Thanks.
Every Oreo based ROM can be flashed over stock ROM, however it will end-up with unprecedented errors, and possibilities of soft-brick/hard-brick can not be avoided.
However, if you are looking for a custom ROM closed to stock, try flashing LOS, for which you need the bootloadwe to be unlocked.

Thank you. I tried that one and it needs blobs from Nougat apparently. When flashing LOS 15.1 over stock oreo, the fingerprint sensor doesn't work.

Some ROMs (mostly pie) need Oreo as base but a lot of Oreo ROMs need Nougat because stock Oreo wasn't released that time, that's also the reason why many Oreo custom ROMs are a bit unstable. Ask the developer what base is needed to be on the safe side.
In your case I recommend flashing a twrp stock nougat ROM:
https://forum.xda-developers.com/g5-plus/development/twrp-flashable-stock-builds-t3813351
After that reflash your preferred Oreo ROM.
If you haven't done it yet make a backup of EFS and persist with the latest TWRP 3.2.3.1 to avoid losing your IMEI and/or 4g.
Read the OP of the above thread:
An important note for those who have flashed custom Oreo roms
It is a frequent issue regarding Oreo roms that the device's IMEI is set to 0 in certain conditions. It is possible that these roms (or something used with them) are tampering with the persist partition of the devices. When this occurs, if the EFS is erased, it is not reconstructed correctly.

I tried doing the backup in TWRP. Not sure I got it backed up right. I have the following files in my TWRP backup folder my external SDcard:
- efs1.emmc.win
-efs1.emmc.win.sha2
- efs2.emmc.win
- persist.ext4.win
- persist.ext4.win.sha2
- persist.info
- recovery.log
Does that look like the correct number and type of files to have for backup? Thanks.
