How do i change from existing rom and kernel to a new rom and kernel?

This is a noob question but i'm still very much new to this.
I have aokp 10/8
and i'm running one of simonsimon's kernels
and i need a guide on how to update my kernel to Jellyboot5 and how to update my ROM from the 10/8 nightly build to the 10/17 stable/nightly build. Someone please provide me with a quick explanation on how i should do this. What should i clear? and how do i flash it and which files do i flash first? All help is greatly appreciated. Thank you.

For kernel you flash it normally ..like you flashed it the first time
For Rom you flash it from recovery and only wipe cache and dalvik cache ..thats it

same way as u flashed 1st rom
flash kernel
wipe data/cache/dalvik
flash rom
reboot
njoy

First go into bootloader
Flash kernel
Then enter recovery without doing any reboots ....and flash the new Rom but before wipe cache and dalvik cache

[Q] Custom Roms / Kernel Questions

I have a AT&T Samsung Galaxy S3 (SGH-1747) that is running stock with root.
I have rooted my phone using the samsung toolkit located here: http://forum.xda-developers.com/showthread.php?t=1746665
Since that toolkit flashed a CWM Based recovery I have installed ROM Manager and flashed CWM Recovery version 6.0.1.2
My questions are..
- with my current setup.. am I technically running the "Stock" samsung kernel?
- why would you want to flash a different kernel to your phone?
- and is it necessary to flash a different kernel in order to use certain custom roms?
- At first I was leaning towards flashing CM10 nightly but the more I look at it.. I want to flash PARANOIDANDROID 2.22 http://forum.xda-developers.com/showthread.php?t=1818199
Is this rom fully compatible with my AT&T phone? and since i'm running stock with root, do I need to do anything special before flashing this rom? Factory reset? Wipe Data? I've already made a full nandroid backup.
Thank you!

- with my current setup.. am I technically running the "Stock" samsung kernel? I believe so
- why would you want to flash a different kernel to your phone? Different kernels do different things.. some have better batter life.. some let you OC and UC..
- and is it necessary to flash a different kernel in order to use certain custom roms?Well sometimes.. Well technically.. most kernels will work with most of the ROMS out there.. as long as you stay withing your phones threads.. But some ROMs have a kernal with them.. and some ROMS you need to flash your own kernel..

Thank you for the reply.
On the rom i'm wanting to flash for my SGH-i747 http://forum.xda-developers.com/showthread.php?t=1818199
The steps for flashing are as follows:
CWM: Install Zip: Rom: Download Here Make sure the file you download is PA-2.22-d2att.zip
CWM: Install Zip: Gapps: Download (These are the new ones)
CWM: Wipe Data/Factory Reset
CWM: Advanced/Wipe Dalvik Cache
Reboot and edit your Apps Dpi & Layout under Settings/Paranoid Settings - DO NOT RESTORE YOUR OLD PROPERTIES FOR NOW
Would i need to wipe data, factory reset, then also wipe dalvik cache BEFORE I install the rom and gapps since i'm running stock with root?
Thank you

i'm also reading that for paranoidandroid you must first flash CM10 then flash paranoid.. is this accurate?

umm.. not sure where you saw that you need to flash a CM rom before flashing the paranoid ROM..
I believe the Paranoid rom is based off CM
The instruction on the link you have, in my opinion, is wrong..
The way that i flash my roms is...
Wipe data/factory reset..
Wipe Cache
Wipe Dalvik
Format/Data
Fomat/System ( i think deletes backups) only do in emergency.aka optional step
Flash ROM
Flash Gapps.
THATS IT
Some people will wipe cache afer flashing a rom..
But if you wipe data/factory reset i believe deletes the ROM...

If you are already running CM10 then you don't need to wipe Cache. Just dalvik and data. Im pretty sure thats what was confusing, since this is based off of CM10.

yeah, I just keep reading and reading.. probably making this out to be more difficult than it really is just don't want to end up with a brick or anything.
I'm already on stock + root + latest CWM so I just need to put the files on my phone and flash but I believe these are the steps i need to take:
1- Download ROM and Gapps to internal sd card
2- Boot phone into recovery
3- WIPE Cache/Delvik/Data factory reset> Mounts and Storage- format system
4- Flash ROM and Gapps

Problem with wiping dalvik cache [XperiaS]

Hi!
Sometimes i cant wipe dalvik.
For example - used XZXperience 1 and wanted to install XZX2, tried to wipe dalvik (can wipe other stuff), but cant, just nothing happens when click on Wipe dalvik.
Using KA kernel 8
Only solution is to flash stock firmware and do all process again, what im doing right now

Tried, not helping.

Try manually by:
Using a file explorer go to data>dalvik-cache and wipe everything reboot to recovery and to what you need there
Sent from my Xperia S using xda app-developers app

flash ics17 kernel, then try again.
Sent from my LT26i using xda premium

Same prob.

This problem related to the kernel you are using.. flash Advanced Stock ICS or Stock+ Kernel and then try again.

I tried, it wont help. Still cant accsess dalvik cache wiping.
Like i sayed: only solution is to flash stock firmware, then root it, and then works. If i flash KAv8 or other stock ICS kernels, then problem comes back.

Go to recovery ,advanced option and mount cache. Than try it again.

Dirty flash

sorry for the noob question what is dirty flash

Flashing a rom without wiping /data first. A "filthy" flash would be to flash without wiping even cache and Dalvik
You can dirty flash between minor version updates of the same rom. Whenever you flash a major update (let's say from bestromever JB 4.3 based to bestromever JB 4.4 based) or if you flash a rom from a different developer you need a clean flash, meaning you need to wipe data, cache and Dalvik in your custom recovery.
If in doubt: clean flash

Custom rom + Custom Kernel = Black screen..

Hi,
When i tried flashing a custom rom and a custom kernel it just gives me black screen after starting up again maybe you guys have got the same problem before and what did you do to solve this issue? I tried these custom rom/custom kernel combinations :
FreedomOS-op3-nevax-1.7-CE-signed / blu_spark_r114-OOS-6.0.1 thulium
FreedomOS-op3-nevax-1.7-CE-signed / ElementalX-OP3-0.23
ResurrectionRemix-M-v5.7.2-20160804-oneplus3 / blu_spark_r114-OOS-6.0.1_thulium_e476ded
ResurrectionRemix-M-v5.7.2-20160804-oneplus3 / ElementalX-OP3-0.23
My TWRP version is 3.2.1 official
These are one of the many methods i tried:
Method 1
1. Wipe Cache, Data, Internal storage, Dalvik/art cache and system.
2. Flash Custom Rom.
3. Wipe cache, Dalvik/art cache.
4. Flash Custom Kernel.
5. Reboot.
Method 2
1. Wipe Cache, Data, Internal storage, Dalvik/art cache and system.
2. Flash Custom Rom.
3. Flash Custom Kernel.
4. Wipe cache, Dalvik/art cache.
Method 3
1. Wipe Cache, Data, Internal storage, Dalvik/art cache and system.
2. Flash Custom Rom.
3. Flash Custom Kernel.
These are some of the combinations i tried and even some of the methods i tried are nonsens but i am just trying to get it to work. If you need any more information just tell me . Help is very much appreciated .

3.5.2 base dont work with custom kernel yet. The twrp Version is a non known at my End. I think you better read this forum. From A to Z. Since all your awnsers can be found easy.

3.5.2 base? Can you please explain it a little bit more detailed thank you and i already read alot and can't find it thats why i made a thread.

Please read the freedom os topic. It address well why you cannot Flash a custom kernel. It is simply that kernel sources for Version 1.7 (aka 3.5.2 base) are not releases.

As suggested earlier try reading some ROM threads, going around flashing ROMs and kernels with no purpose is going to get you a soft brick very quickly.
My suggestion decide what you need out of a ROM, that is missing from stock, read a few rom threads to identify one that fills your needs. Then when you've got a ROM in mind go back and read the thread THOROUGHLY before flashing, had you done this with FreedomOS you wouldn't be here now.
