Flash back StockROM after flashing CustomROM - Galaxy S III Q&A, Help & Troubleshooting

Hello guys ,
i have got a question. If I install CWM and CyanogenMod, can I reflash StockROM without any problems (with Stock Recovery and original kernel,baseband and csc)?
Can I use a one-piece flashfile for that or I have to use a three-part flashfile?
If I have to use a three-part flashfile, where can I get it? On samfirmware.com are only one-piece firmwarefiles...
Greetings...

Shouldn't be any problems, back up sd card in case you need to factory reset to get it to boot

And if I flash CyanogenMod, how can I reflash the StockROM with all original things, like CSC, Baseband etc?

I'll use pre-rooted stock rom from here . All things you've asked are included in package. If you use TA and do Factory Reset your phone will be rooted and Official/Normal at the same time

CSC is Samsung feature, not included in cm/aosp, modem....just make a note of you baseband, and if the Rom flash changes it just re-flash modem

Okay, but if I wanna flash the original unrooted ROM, how I must do it?

Use Odin and flash Stock ROM from here

Download the stock rom of your choice from SamFirmware, then flash with odin. Then boot into the phone's recovery and factory reset then reboot and voila.

Yes, in a 1 part firmware you get csc, phone, modem

So you say that in a 1 part firmware are the same files as in the three-part firmware? That's nice! ^^

That's very nice...
Before I got my SIII, I used a Galaxy Fit and there I needed all files to flash my Firmware...
That's very nice to hear. Then are the other fields for files only for that if I especially want one of these files and not for flashing a new ROM?

Yes, it's optional. If you want to use for example a Rescue Firmware you'll need much more files and then more options must be ticked

Thanks, and this Rescue ROM is for making a factory condition?

Yes and No. I've just used it as Example to explain why there's more options in Odin. Rescue ROM is for bricked phones, if you flash accidentally with wrong ROM it can bring your phone back to life

Yes, but do not use unless you have too, it contains a .pit file which is the partition layout, .....not to be messed with unless absolutely necessary

Flashing the stock kernel?

I am thinking about installing a custom kernel and was just wondering how easy it is to install the stock kernel back if I need to? Do I have to do a nandroid backup and full restore or can I find just find the stock kernel somewhere and flash it?
Regards,
BTJ
it's not hard....
easiest way....go download original stock firmware from other thread....
to put original back, simply flash it with mobile Odin....or Odin

Oh, then it seems to be more complicated. Have you tried to flash 4.0.3?
What process did you use to flash LPT?

i did it.
now i flashed siyah 4 and i installed CM9 from CWM and all ok now
but i want to use this rom i will try to flash it again
is it safe?
Yes LPT is safe I'm on a modified version of it right now. It's not the ROM but the kernal that is the problem with certain 4.0.4 leaked ROMs. If you use siyah as your kernel you will be safe.

do a factory reset to be safe. if you want to be even safer flash mega wipe from one of the threats, but usually factory reset should be enough.
the factory reset on setings?

No idea why you don't want flash full firmware, there nothing wrong at all
Yet, just use mobile odin pro, open file, choose the stock rom, then clear everything except recovery

i dont have Uk kernel but you can try MF1...it's better http://d-h.st/pPv
if you have firmware package just open it with 7zip, winrar , winzip etc. and take kernel.bin.md5 , after that you can add it to tar package and flash with odin or flash it using universal kernel flash
