I know flashing an custom kernel will increase the flash count, but if I flash a stock kernel but only use custom ROM would that still increase the counter?
Flashing a custom kernel only increases the counter if done from download mode (i.e. with Odin/heimdall). Most custom ROMs are flashed from CWM, and if you do that, the counter will not increase regardless of whether it includes a custom kernel.
However, if you flash a custom ROM from download mode and that ROM includes a custom kernel, your counter will increase. If you come across a custom ROM which is flashable from download mode and does not include a custom kernel, it will not increase your custom binary counter.
It's largely irrelevant anyway with the likes of a USB jig or TriangleAway. If you didn't want to use either of those and already have root from a method such as zergRush, you could always use Mobile Odin to prevent counter increases.

ok guys i odin the stock rom with root, how in the heck i get into recovery mode and install cm7? i tried rom manager and it didnt work any other ideas?
Rom manager does not work correctly on stock. (It will work once you are on cm7.) You need to install a kernel that contains ClockworkMod Recovery. If you install the kernel with Odin or Heimdall, it will increment the flash counter and cause the initial I9100 boot screen with yellow warning triangle. If this is a concern to you, use the Guide linked in my signature to avoid that.
Does anyone know if flashing the custom recovery also triggers the counter yet. No definitive answer from the search.
First post of Chainfires [PRERLS-REF] Root, BL, Kernel, Recovery says "Whether or not flashing a custom recovery also triggers this counter is as of yet unknown."
I'm planning to use Custom ROM for my JB using Custom Kernels from my Rooted ICS, and I have questions and doubts. Here's the steps and the Q's they have:
So, here's the steps I planned based on my S2 Guide Surfing:
1. Root my ICS (Done)
2. Flash Stock JB Official Firmware via Odin XWMS1? XWMS2? or XWLSW?
Questions Regarding This Step:
A. Do I have to backup my /efs folder from ICS here?
B. Do I have to Wipe Data/Factory Reset + Wipe Cache BEFORE/AFTER flashing the JB Firmware?
3. Flash Siyah? or DorimanX? Kernel via Odin
Questions Regarding This Step:
A. Can I run these kernels on my Stock JB ROM (if succeededly flashed)?
B. If I do a backup on Siyah via its CWM, and changed to DorimanX, then noticed that the kernel's not my type, can I restore my backup from Siyah's to DorimanX's CWM? Or does the both kernel have the same CWM?
4. Flashing Custom ROM via Custom CWM
Questions Regarding This Step:
A. If I flashed a Custom ROM which has a Cusrom Kernel inside (like NeatROM, I suppose), will it be overwritten my Siyah/DorimanX kernel? Or they will still be there?
Thanks for Noticing My Questions! And Very Thanks for Answering Them!
1) Yes, I'd backup up EFS immediately after you root your phone (and even before you do a nandroid backup with CWM). Use Hellcat's kTool from Google Play (and buy Hellcat a beer after you download it).
2) No. No need to wipe when flashing stock firmware (you can if you want though if you like a really clean install) because you're going to be wiping before you do a custom rom install anyway.
3) Yes. You should be able to run Siyah or Dorimanx just fine on stock JB (make sure you choose the right build though; read the threads devoted to these kernels to work out which build you need).
4) Yes, if you do a nandroid backup with CWM while running Siyah, and you switch to Dorimanx & decide you don't like it, you can restore your backup & go back to Siyah.
Though you could just easily re-flash Siyah with CWM to achieve the same result. That will probably be quicker than restoring a backup (say, 2 minutes Vs 10 minutes). If you re-flash a kernel, just the kernel changes, none of your settings/apps/anything else does, so restoring a nandroid just to go back to a particular kernel is overkill.
5) Yes. If you flash a custom rom, the kernel bundled with that rom will overwrite/replace your current kernel. If you don't like the kernel bundled with the rom, you should be able to use any other kernel you want with it provided the kernel you want to use works with the base of the rom (I.E the kernel you want to use works with TW roms if you're running a TW rom, or AOSP if you're running an AOSP rom) & the Android version of the rom you're running. Again, read the thread devoted to the kernel to determine compatibility before you flash it (worse thing that can happen if it isn't compatible is the phone will bootloop though; unlikely to brick your phone outright).
Would the following work as a way to try out, for example Cyanogenmod 10. I am currently running a 4.1.2 install (pretty much stock just rooted/cwm via Philz as per the tutorial). I have a complete backup made via Philz recovery of this rom along with the kernel (which I believe is still stock from that) and efs.
1) Install a custom kernel (eg. dorimanx 9.x?) via the Philz recovery.
2) Install cm-10.2-20140102-NIGHTLY-i9100.zip.
3) To return to the original rom, reflash the original kernel (with whatever CWM is included in dorimanx) - then reflash the backed up rom via the same recovery?
I hope this is clear enough a question.
I believe you have to flash a stock rom through Odin, to return to complete stock. Just flashing a stock kernel isn't enough, and is surely not going to work (so don't do it).There are also tutorials how to remove the yellow triangle afterwards.
Please correct me if I'm wrong

This is the part I'm most unsure of. Ideally I'm trying to figure out the process that lets me go from CM10.2 (and whatever recovery) to the point I am running the backed up rom rooted with PhilZ-cwm6-XWLSW-XEU-5.06.1-signed.zip again. Very confused on how to do so.

Topher,
If you have rooted and cwm via philz, you already have a modified kernel installed. I believe the philz-cwm6 should be as close to stock kernel with the CWM incorporated. You don't need to add another kernel, because it will be replaced when you install the custom ROM. You should just be able to flash the cm10.2 via philz or via odin. You can then flash the dormanix kernel if you want - can't comment on that kernel - or if it has cwm included.
I would also suggest that you consider backing up you /efs folder (one with you imei information etc) prior to flashing any custom roms. People have been using hcKtool to do the backups and also an actual copy as well.
Depending on the custom rom, you may have connection problems with your network. So you may want to consider keeping a copy of your modem.bin file from your stock rom handy in case you need to flash onto the custom rom.
If you want to go back to stock, then you just need to flash the stock rom - you can check sammobile website for your stock rom or use the backup that you made.
I should point out that I have yet to do any of the above - I gathered this from reading the forums. Some more experienced forum users can add corrections. I rooted my phone a couple of months ago and now considering installing custom rom in the next couple of months.
Thanks.
if u flash a custom rom (cm10.2 for example), it already included kernel as well. so if u want to try out other custom kernel, i can flash it after you are done flashing a custom rom but make sure it is compatible with your android version. (u cant use custom kernel that not support android 4.3 with a custom rom running android 4.3)
Is it possible to install custom ROMS and custom recovery without root
Define root.

Usually, you flash a custom recovery using ODIN with the phone in download mode, so you don't need root for that.
Almost all custom ROMs come already rooted. So, if you flash a custom ROM either through ODIN or the Recovery, you should get root automatically. The only exceptions are Stock ROMs where someone has either debloated or de-ODEXed the Stock ROM.
