I've been reading that the leaked kitkat touch wiz Roms have a new bootloader and you cannot flash back. My question is, do kitkat AOSP Roms have this new bootloader as well? I want to flash an AOSP Rom but don't want to get stuck.

Unsure what they mean by stuck... Flashed latest cm and decided I didn't like it and just restored my latest cwm backup which was to jedi and I have had no issues. Would love an explanation too.

Thanks for the reply, what I mean is I've read flashing a tw kitkat Rom with the new bootloader prevents you from flashing back to a 4.3 Rom (what I meant by stuck). I was wondering if the same would happen if I flashed a kitkat AOSP rom. Seeing as you were able to flash back I guess my question is answered.

Custom ROMs like CM don't flash bootloader changes, so you can go back if you want.
Official TW ROMs flashed via Odin or OTA update typically contain bootloaders.
These are the ones that you want to avoid.

Can i root my phone and just keep stock ROM ? I just want to wait for new roms to be released on new base...
Yea rooting always leaves you stock first. Its always an option to flash a custom ROM.

So I'm coming from cm10 on my phone. I have tried to install to touchwiz base roms and after installing the screen turns black right after the boot screen that says galaxy s3. Wondering why? Any tips?

AOSP kernel maybe? I know some (all?) of the stock based ROMs don't flash a kernel. Just a guess, haven't gone from AOSP to stock.
Do you have a nandroid of a touchwhiz rom ? I go back and fourth to cm10 to my stock nandroid backup without issue. Try that.

It looks like I need to flash a Touchwiz kernel, you are right. That fixed it. Thanks!

What kernel did you use?
Sent from my SAMSUNG-SGH-I747 using xda premium
Kernel was on my mind today since I went from WanamLite to DietICS and suddenly WiFi stopped working. It was because I had flashed the faux123 kernel while on WanamLite and had to reflash it after going to DietICS. Little things I'll eventually get used to!

Yep definitely kernel, would a said so immediately as I had same issue. Always be weary of the kernel u have installed when flashing to new or different rom as many roms dont have a kernel with them. And many custom kernels will cause this issue. U got it figured out anyways so live and learn and keep it in mind for future

I am currently on aopk right now and I am planning on flashing something else. The question is.. Do I have to put my phone back to stock to flash a new rom? What's the easiest way to flash a new rom while currently running a custom Rom?

The new rom you want to flash will have instructions in the original post. Check there

Compete a full wipe and install the same way you did your current custom ROM. No need to return to stock.

Unless your going from an AOSP or AOKP or CM10 rom to a stock based rom such as Ultimatum that are on different versions of JB (4.2 to 4.1.1). You would most likely soft brick if you did not go back to stock first.
Other than that it is not necessary.

Actually it won't, you just have to do a factory reset to wipe data, then flash away. No need to flash back to stock.

As the topic said, is it safe to downgrade from 4.3 , knox free custom rom to 4.1.2 custom rom?
another question is, once I installed any 4.3 knox free custom rom, is it safe to restore my 4.1.2 rooted stock rom backup without any problem?
For both question I use philz recovery.
I dare not to flash any 4.3 custom rom if I can't find any answer.
Thanks in advance!

I am not trying to scare you but I have read people saying their phone is ****ed up after flashing 4.3 rom. Now they want their phone to just work. if you're lucky you will run 4.3 flawlessly otherwise you will post a thread asking about how to make your phone work again

As per my knowledge there is no issue to downgrade from knox free ROM. However you needs to read a lot to do so. :laugh:

I haven't ever flashed any TW roms. I'm switching over from an AOSP rom. Do I need to flash the modem and bootloader first or can I just flash the rom?

I guess it depends on your device, the AOSP ROM you are coming from (ICS, JB, or KK), and what modem and bootloader you are currently on. For the d2att either the MJ2 or MJB bootloader and the MJB modem will work. If you have one of the Canadian devices the modem and bootloader required will be different. (MK5 ??)
You may also need to flash back to a stock rom before going to S3Rx in order to get the partitions reset. You can verify this in the ROM thread, I think I saw it there.

I'm on PA, AV 4.3.1. I'll probably reflash the stock rom and the MJ2 bootloader and modem. Then flash the new rom. I'll read through the rom thread too during lunch.
Thanks for your help.
