Custom kernel and stutter - Samsung Galaxy Express GT-I8730 Questions & Answer

In this topic there is CM13 and then a custom kernel for CM. My question is, is that kernel the same one included in CM13? If so, why is it posted? If not, what changes?
I installed CM13, then flashed that kernel and gapps (cleaned cache, data, everything, with TWRP) but for some reason it stuttered a lot. Google play crashed every few moments and the file explrorer couldnt even open. I tried restarting the phone but it didtn change anything.
Then I tried installing exactly the same ROM again and the same gapps but without the custom kernel, and now it doesnt stutter or crash at all.
Could these problems be caused by the custom kernel, if it was different than the stock CM13 one? Or maybe I had just an unlucky flash?
Now that I think this would be an overall question, not just focused in the i8730...

[i9506] App Optimizations Loop?

After trying to install the CM12.1 (http://forum.xda-developers.com/galaxy-s4/i9506-develop/cyanogenmod-12-android-5-0-lollipop-t2954832) ROM, Kernel and GApps, it just Goes to the Optimizing Apps then goes back to the CM Logo, it just loops at this, any idea what the issue might be? Clean Install, done multiple times, tried different kernels and GApps, always the same issue.

Flashed CM13, Cannot find Gapps package that works, help?

Hey everyone, I rooted my phone, unlocked the bootloader, flashed TWRP, and then flashed CyanogenMod 13 (Marshmallow). Everything worked perfectly, so I went back into my recovery to flash Gapps. I've tried Open Gapps and Slim Gapps, but both repeatedly crash setup wizard and clock among other things.
If anyone could help, I'd really appreciate it.

These are the Gapps that worked for me

Thank you for the help wikked26, but it didn't work. Those Gapps still crash for me. I think it's something incorrect in the way my phone is configured, not a case of downloading the wrong Gapps.
If anyone has any other ideas, please share them! I haven't cracked the case just yet
I know I was having issues with the Slimroms version where I booted into CM and set it up before installing Gapps. Fixed it by reinstalling/wiping the cache and installing Gapps before booting anything. Don't know if that helps, but I'm running fine now.
I'm hoping this is similar to the issue I'm having. Do you get it where you can factory reset in TWRP, then flash CM13, but when you go to flash Slim Gapps? Because I figured out that after factory resetting TWRP will only successfully flash 1 zip file. I also tried to wipe the cacher, dalvik, data, and system, then flash cm13 but Gapps still wouldn't flash. Maybe its a bug with TWRP 3.0.2? I'm going to try to use a different version of TWRP and I'll update with my results
EDIT: TWRP 2.8.5 did not do anything different
Wow, thanks for all the great responses. I made sure to try and install CM13 and Gapps at the same time, before boot, after wiping everything one last time. It worked flawlessly, and I can now use Google Play Services.
I hope this thread helps anyone else who is also a little stuck. I also found that TWRP didn't have any issues flashing multiple zips at the same time, not sure whats going on with you, Orange Officer. Perhaps try removing your battery after CM13 flashes, and then boot into TWRP again and flash Gapps without booting up CM13 at all?

trying to flash frank kernal --> bootloop

Alright, so I'm thinking my problem was that i initially had supersu installed when attempting to install this kernel, and thus causing that bootloop.
Can anyone provide insight as to whether this is true. I had a nandroid backup of my stock rom and even though I "restored" it, it was still stuck in bootloop regardless :/. I don't want to keep restarting and reinstalling everything over and over without knowing what the problem is.
I currently run Resurrection Remix with xposed. I'm fearing if I make another nandroid backup for this and try to flash the rom again, it won't work and I have to start again.
FYI: I was on RR when I attempted the kernel install.
Try downloading the kernel again and dirty flash it. If that doesn't work try dirty flashing some other kernel. And if that doesn't work dirty flash your rr rom. And if still not working then restore your backup

well what i did was following:
round 1. RR rom already installed
wipe cache and delvik, install kernal, bootloop
attempt to restore nandroid., still bootloop,
attempt 2:
wipe everything and install RR, SU, Gapps
did setup
installed franko r25
attempt 3.
wipe and factory reset
restore nandroid
bootloop
attempt 4

omg thanks! that worked perfectly. Now a new problem is specifically when I'm using tugapower, while typing on my swiftkey into the xda forum. I'm noticing a lag. I've made it so then both apps are operating on performance with franco. Not sure what's causing the lag. Is it possibly the theme?
Dunno whats the problem, but im pretty sure if you just flashed franco, didnt change anything and used those apps, they wouldnt lag
didn't figure out what caused the lag but its gone now

Is it possible to dirty flash cm.zip over the same flashed cm.zip?

My camera is not working since i have flashed the Boeffla Kernel. I tried different camera apps and no one is working. I get a camera connection error everytime, does not matter which app i try.
Because of that i want to flash cm again via dirty flash.
But is it possible to dirty flash a cm.zip over the same cm.zip which is already flashed?
I know that it works if you flash a newer version but will it also works with the same version?
Edit: i have cm13.0-20161013 at the moment.
If there is any cm based rom which is newer and can be dirty flashed over it, it also would be okay. It just should not be Android-N because i just downgraded from it a few days ago (because there is no xposed for N yet)
Edit #2: I just did it and it worked perfectly, thread can be closed, thanks anyway
yes, you can dirty flash the same ROM zip over your current ROM, esp if youre having kernel issues. Thats the main reason why people would dirty flash if youre experimenting with kernels. just wipe the caches a few times (i ususally wipe them 3x just because it seems to work the best), but short answer is yes, youre good to do that

[T560] All Android 7 ROMs not working, stuck on bootloop

Hi all,
so I can't install any Nougat ROMs as they all make my device go to bootloop on the first reboot after flashing, and just keeps the device on the boot animation for hours
This includes LOS14.1, DotOS and ViperOS all versions.
When I flash the CM13 ROM (what I'm using now), everything works normally on the first try.
I can't be the only one experiencing this bootloop, anyone else having these issues?
Did anyone else get bootlooped? Did you manage to circumvent the issue?
Any help is appreciated

Did you flash magisk or supersu before fist boot?
I tried with and without rooting, of course before flashing the ROMs (and GApps) I would wipe everything except sd card.
Really don't know what's the issue as the majority of people that reported bootlooping on these ROMs managed to get it fixed later, but none of that works for me.
I tried restoring back to 4.4 then trying again, I tried leaving the boot animation until the tablet runs out of battery then trying again, still no luck.
When I flash the CM13 rom from xda, everything works fine on the first try and first boot takes only a new minutes. I also managed to install the CM12.1 and the latest LightROM for the t560. Weird
Anyway I can only hope this gets resolved, willing to try anything as I don't use this tablet for anything relevant. It's the UK version, if that matters.

Make sure the ROM is for your Device. T560NU has a different chip set that the LTE model and you can't interchange roms.
