If I upgrade my firmware, will my kernel/recovery get replaced?
Example: I have a SGA2 w/ 2.3.6 Gingerbread w/ a custom kernel and recovery, I decided to upgrade my firmware to SGA2 4.1.2 Jelly Bean. Will my custom kernel and recovery get replaced by that upgrade?

Yes - for ACE2 kernel and recovery are (usually) on the same partition. If you install JB you'll get an new kernel (of course) and recovery.

A few months ago I flashed xzxperience 2 rom and RaymanFX kernel, this was before official Jellybean rom from Sony was released. My bootloader is unlocked and I want to install official the Jellybean update now. I tried DooMlords rom but it wont flash.
What do i need to do? I dont think I backed up stock kernel as I cannot find it, only stock ICS rom I backed up using clockwork recovery (does that back the kernel up I wonder?)
Can I just use Sony PC companion or OTA update?
Thanks.
No, you can't use PC companion or SEUS when you have an unlocked bootloader.
Have a look in the FAQ of the XPERIA S Development forum and see if there's a ICS ftf
There should be some ICS .45 and .55 ftf files around somewhere.
I believe you can now root .55 so it should speed up your progress to an install of the pre-rooted JB ROM.
That said, DooMLoRD provided a few fastboot 'elf' kernels that you can use to get CWM recovery mode access and then flash the JB pre-rooted ROM.
Best to have all the zip files you need on your phones /sdcard before you start any process though.
If you can't flash the pre-rooted official 6.2.B.0.200 ROM, you can install a leaked version of JB, then install DoomKernel, and you should be able to install the pre-rooted official 6.2.B.0.200 ROM and then DooMKernel again. that's the long way of doing it.
I believe if you're getting a status 7 assert failed, DooMLoRD has a fix for that too, with an ICS kernel/CWM recover of some sort.
I believe there are pointers in DooMLoRDs pre-rooted JB ROM install procedure.
As an aside, I had RaymanFX GPU/CPU over-clocked kernel installed too and found it really good.
You can use EMMA tool from Sony for unlocked bootloaders to go back to stock rom or flash a .200 ftf file with flashtool.
Other option is to flash Doomloards prerooted ROM with CWM or in case you don't have CWM (or CWM on ICS kernel and errors during flashing), first flash Doomlords advanced stock kernel which includes CWM via fastboot / flashtool and than his ROM with CWM.
thanks for the replies guys, I managed to get the doom stock jb rom working in the end, followed the tips in the thread and had to flash Advance Stock Kernel with Recovery v01 (FW 6.2.B.0.200) (CWM 6.0.2.7) before I could install the rom
I will remember in future then if I want stock rom to relock the bootloader.
I used kies to go back to stock and then rerooted. when I tried to install a tw kernel I got a soft brick. Unlike a custom ROM you can not just do a recovery back to before so I am afraid to try another kernel till I know.

I have a rooted AT&T galaxy s3, rooted with a custom kernel. I also have twrp and have been able to do a backup (nandroid backup) of the stock rom with stock kernel and stock rom with custom kernel. Sounds like you made sure the kernel specifically states TW, so not sure why you had this problem but I have used it...did you install custom recovery ?
Hello ...
two days ago i've unlocked and flashed custom kernel & rom (Super JB) on device Arc S LT18. I, and don't know why, used Flashtools to recover to 2.3.4 and after that installed the mentioned rom (yes i've cleared all). Now the device only boots if i use Menu + Power button. What the hell ? If i only use the power button, the green light flashes and nothing else (no boot). DO i need a clean wipe and all over again? Maybe i must flash original kernel 5.4. ?
After flashing the ROM in recovery, did you flash the patch for your device as mentioned in the installation instructions?

yes, i've flashed the patch after the rom. I really don't know what happened, was it the flashed kernel (that is the first time i've encounter the problem) ? or maybe that i've installed a stock rom (2.3.4) and didn't boot the device (and then proceed with the custom installation) ? or maybe it's the kernel, because i've flashed the Super Fusion and not the fusion 5.4
now i've installed the official CyanogenMod 10.2, but can't seem to fix this bug

you need to flash ics stock firmware 4.04 first then you can flash custom kernel then custom JB rom
jb rom cant's be flashed on gingerbread 2.3.4 roms, you have to be on stock ics 4.04

What difference does it make, if both kernel and /system partition are completely formatted anyway?

its your choice mate if you want to be on GB rom then flash gb 2.3.4 or if you want to be on ICS then flash ics 4.04 stock rom
but if you want to flash JB custom roms then you need to flash ics stock rom first.
you can either reover to ICS or GB via flashtool its upto you
well the cm 10.2 works really good and maybe i will test cm 11 (or any custom rom from 4.2 above). so i will try your suggestion and see what happens.
EDIT: well the stock browser crashed today -.-' ... will have to test further ... and the strange boot is kinda fixed (it was my fault because i didn't pushed the power button long enought lol)
EDIT 2: stock browser simply force close everytime i use it. google play store doesn't work well :/
I found leaked version of 4.3 update on internet called UCUEMJ2 and then flashed the Knox-enabled leaked version.
Now I want to flash CyanogenMod on my phone. Is it safe? I heard it can brick phone because of knox. If it's safe then how to do so?
You could use Odin to flash a custom recovery which allows you to flash a custom ROM.
I don't think you need to flash the leaked 4.3 ROM before installing 4.4.2-based ROMs. At least I didn't have to.
its safe to flash rom from leak mj2 to cyanogenmod.. i flashed CM11 last week via CWM Recovery...root it first then update ur SuperSU to disable knox then install custom recovery, backup ur current rom then flash Cyanogenmod...
I'm only rooted... on the STOCK firmware
I'd like to install that kernel:
http://forum.xda-developers.com/showthread.php?t=2415862
But it says: ONLY SUPPORTS Android 4.2.2 SAMSUNG STOCK BASED ROM
Does it mean that I won't be able to install a custom ROM after flashing the kernel??
Or it just mean that I must be on STOCK to use it?
Also, I'll use that recovery: PhilZ 5 recovery to flash the kernel: forum.xda-developers.com/showthread.php?t=2287802
is it OK?? or I should use TWRP (I read that TWRP is better than CWM)
Another Q:
If I had problem with the kernel, is flashing the STOCK one easy?
(I want a link to a stock kernel of N5110 just to be safe)
Finally, would flashing kernel reset my device and wipe all of my data?
Thanks in advance
