Can a kernel affect signal and data quality and will a custom kernel keep you from getting OTA updates?

it is possible.
what do you need a custom kernel for?
if there is no real reason to switch out the kernel, why would you?
Well, I have a HTC One M8, and flashed a stock GPE rom with stock kernel, after a couple of days I tried flashing a stock GPE rom with some modifications and a custom kernel. Dont know if it was just me or if the consistency of my signal got better with the custom kernel.
Anyhows, I dropped rom's for my device and flashed an RUU instead. Now I get the GPE OTA's and keep everything clean. Thats why, I was thinking about flashing that custom kernel to my stock GPE RUU. As a sidenote, I use the same radio my HTC was delivered with out the box. Ah, another question, do I have to reflash my radio after lolli OTA?
Edit: I dropped rom's.., I didnt dripp them...

I currently have a brand new Canadian S4 with the MDJ firmware/baseband version.
Most of the roms are MDL based.
Do i have to change the base firmware/baseband to MDL before flashing and MDL rom ?
My goad is to install CleanRom wich is MDL based.
Thanks for the guidance.

You can just flash the ROM. Just make a Nandroid backup first. Some ROM's come with a custom kernel and you may need to flash a Canadian kernel directly after flashing the ROM.

I did get the original Kernel file for my cell provider. It is a TAR file with boot.img into it.
What is the easyest way to apply it after flashing the Rom in TWRP ?
Thanks

TARs are flashed with Odin or Mobile Odin.

If you are flashing the STOCK firmware for your specific carrier it will include the STOCK kernel.
If you are using a custom ROM like Mint Jelly or something, I'd say flash Adam kernel after flashing the ROM. You won't want to flash a STOCK kernel with a custom ROM.
Did you end up updating to MDL?
I also have the MDJ kernel and I installed CleanRom, I now cannot get wifi and TWRP will not boot in recovery mode. I thought it would be easier just to update to MDL to get wifi but mobile Odin did not work.
Thank you

No I did not,
Truthfully I am a pretty big Noob to all of this and was afraid of changing my kernel to MF3 from MDJ. I really didn't know how that would affect my phone / carrier situation here in Canada. The main problem was that I could not get the phone into recovery mode. Turns out I just needed to re-root the phone. So when I got the phone to actually go into recovery I jumped at the CM Rom. When I find a forum that helps me understand what updating my Kernel does to my phone I will try to update Kernel and go back to CleanRom. I kind of miss multiwindow.... maybe a little bit of Touchwiz...
Thanks for the reply!
EDIT : I also found this : http://www.scottsroms.com/downloads.php?do=file&id=421 which is a version of CleanROM made for the MDJ but it is dated further back which threw me for a loop too.

No worries and you're very welcome! Don't sweat, I'm still on stock ROM because I'm hesitant to make the ROM dive. Don't know how or if installing MF3 kernel via custom ROM would affect the phone in terms of rooting or custom recovery either. I'd probably be sticking with MDJ build if possible.
You and me both on multiwindow! Helps a ton when it comes to referencing something while emailing/texting! I'd miss the TW camera as well ... maybe. haha
Which version of TWRP are you on? Version 2.6 has an often-experienced issue where it just hangs at the "teamwin" splash screen. Downgrading to 2.5.0.2 resolves that.
Any updates?

Hey guys,
I am also a 1337m Rogers S4 (MDJ) owner, also a noob as well. I managed to flash my phone with CM and had a pretty good AOSP experience and learned a little bit on the way. I can legitimately say that I miss a couple thing about stock / Touch wiz, mainly the multiwindow support and camera. Cyanogenmod is also acting up and drains battery pretty bad when I am roaming in the states.
What did you guys end up doing? Did you update your base-band to mdk and install CleanRom? Right now that looks like it's my goal but I truthfully have no idea how to do it.
Did you guys go back to stock after changing? Do I just find a stock ROM on the forum and use ODIN to bring it back?
Is switching roms as easy as choosing something in Goo manager or do you need to go into a recovery in recovery mode?
Thank you!
As title, looking for the 4.3 touchwiz based rom's that work with the old bootloader.
Almost all custom roms you can flash from recovery won't update your bootloader. I recommend omega.
Read OP of any rom and you will sure notice that the bootloader will remain untouched after flashing.

There will be no issues like lack of sound, wifi etc?
Been using GE roms since the new bootloader was introduced but I have read posts from users having problems flashing new firmware with old bootloader, or is that just for the official roms?
As long as you have the latest modem (MJ5) there won't be any issues.

I'm already using that modem so might just give it a try.
Thanks for the help.
Be sure to have the latest philz touch and you're good to go!
Flashed Omega V19, all working.
Definitely not as smooth as the GE roms but it 's not bad, also it's nice to have the Samsung Camera back again.
Also give echoe rom ago, I'm on old bootloader and mk9 modem, working much better than 4.2.2 stock

Thanks, might give that a try as Omega just started rebooting randomly..
Will try another kernel, if that doesn't fix it then ill try echoe.
All custom roms since 4.3 gave me random reboots once every couple of days.
I'm currently running omega v19 and the uptime is 48h.
Well I got Omega stable with KT kernel, but found the lag a bit annoying so tried echoe rom anyway.
Sadly the lag is much the same, I guess it's a feature of touchwiz and nothing can be done about it.
Why havent Samsung fixed this? it's almost the same as the original roms that phone shipped with.
Hello , i looking for a stable kernel for my kit kat 4.4.2. I have lg d802, whit root and recovery and old bootloader i think, i instal rom from recovery... Any one nows have a experience of a good kernel?

This is the new stock kernel for 4.4 that let's you flash 4.4 based stock Roms strait from 4.2. You must also flash the baseband when going back and forth. (I think this is what you asked for)
If youre talking about a modified stock kernel for 4.4, then no. No one has anything out yet. And more then likely won't for a bit after all devices have access to 4.4

Normally no.
But why would you flash stock, root, and re-flash custom roms?

The stock is not better because the custom roms are based on the stock.....that is if they are tw based.

Have you tried the GPE roms? It has been the most stable and hassle free rom I used so far.
Or try CM12.1. I use it currently in combination with Ktoonsez 5.1 kernel and it works with no problems. Also it is a lot smoother than 5.0.1

i have the i9500 variant, so GBE roms wont work, and CM12 or CM12.1 are good, but battery life is horrible, and the camera is s***....i tried cm12 couple weeks ago, its smooth enough but the camera i not good, AOSP roms have bad cameras....

your right, but sometimes custom roms breaks some functionality, so maybe its a bit better, i dont know for sure...
I am looking for a TWRP flashable stock 10j rom, complete stock or close to that. Is there anything like that.
I don't care about modding much, just need a reliable rooted rom.
I tried a few different roms in the last few days, and all were having issues one way or another.
Stock rom is always is the most stable one.
I could use LGUP to go back to complete stock and then root again, just trying to save the trouble again.
I second this request. Having a hard time finding a ROM without something important broken.

Stock is definitely a solid choice in terms of stability. NotSoStock is close to stock but has kernel tweaks. Some of the others seem to have stock kernel but full of other audio/visual enhancements.
You could try the stock deodex debloated rom which is going to be as close to stock as you will get.

stock deodex debloated rom was never updated to 10j, that's the problem. It's still in 10d version.

thought it was at least 10i. Any chance you know if there is documentation around about the changes through these versions? I haven't yet checked for those changes and actually still searching for good rom myself. I'm not a fan of the ones that can't use second screen at all.

On all the stock roms you can use the second screen. OvrDrive, WETA, NotSoStock.... they are all good roms, just too much modification for my liking.
I would be happy if I could use a simple rooted stock rom with a custom kernel.
Has there been any change to this? I'm still looking for a stock TWRP flashable copy of 10j for the H918.
I made a twrp flashable stock 10j rom about a week ago. I did it for the same reasons you mentioned. It's not rooted, but I just flash magisk right after it. I'll try to upload it to mega tonight. It's not tested but it works fine for me.
