Hi all.

I hope this is right place but am a bit confused reading other threads.

Do I need an sd card in my phone to do this?

What is best one crynaegmod or Noname?

And is there a simple step by step guide for doing this?

Cheers for any help
 
Which s3 are you using? And no one can tell you which ROM is better, you have to try them and decide for yourself. If you're rooted with custom recovery, just wipe, and flash ROM and gapps.

Am using the UK version of the s3. And not rooted or nome of that yet that is why I was looking for a easy step by step guide
 
No version of the GS3 requires you to use a SD card to install a custom ROm of recovery mode, it just makes it a lot easier.

If you're running 4.0.x - 4.2.x, you're fine, and can install any ROM you please, with certain limitations (I don't think 4.2.x supports Cyanogenmod 9 or above, for example).
If you're running 4.3.x or above, your bootloader is locked, and there is, as of now, no way around it (however, there are a couple companies that can offer a downgrade to 4.1.2 with a downgraded bootloader, with mixed results, according to those who have used them), so there is NO way of installing a ROM that is not Touchwiz based.

If you're running 4.0.x - 4.2.x, here's how you do it:

1. Download a custom recovery mode (TWRP and Clockworkmod recovery are the two most popular, though, I prefer CWM, but the choice is yours), download whatever ROM you wanna stick on the device, and download the gapps file (for AOSP based OS's) for the version of Android you want on the device.
2. Hook your phone to your computer and run Odin (make sure Odin recognizes the phone is there).
3. Click on, "AP," and select whatever custom recovery mode you've chosen. Odin will install it to the phone.
4. When the new recovery mode is installed, power down the phone, and enter recovery mode (Go into recovery mode by pressing the volume up button, the home button, and the power button all at once, however, when some blue text appears on the top left of the display, release the power button. If the install was successful, it will enter the recovery mode you chose, if not, try it again, or look for solutions, I never had any problems with it, so I don't know what may cause it. Sorry bro). Make a full nandroid backup as well (just backup the phone).
5. Once you've made sure that the recovery mode was successfully installed, and a full backup of the OS you have is made, reboot the device.
6. With the phone still connected to the computer, create a new folder in the SD card (label it whatever the name of the OS you're installing is (ex. Cyanogenmod11) and move the ROM and gapps files to that folder on the card.
7. Power down the phone, and enter recovery mode again.
8. Wipe the cache for the device, as well as the dalvik cache.
9. Install the ROM and gapps files from the SD card.
10. Reboot, and enjoy your new ROM.

NOTE: This was how I did it two years ago on my AT&T GS3, and I'm not sure if that's still how you do it. I did it on 4.1.2, before the bootloader lockdown.

Good luck.

Well only the Verizon s3 has a locked boot loader. I have the sprint version with 4.4.2 KitKat, no lock. Just flashed cm12.1 and aicp 9.0 (android 5.1.1)
Not sure where to tell op for the UK version though. Might need to check international s3 forums.

Are you sure about that? I seem to recall seeing that the AT&T bootloader was locked down as well.
If I'm wrong, I'm sorry, I just thought it applied to all phones.
 
As far as I know Madbat is correct, it's just Verizon. Definitely not the international model like the OP has. Rooting and flashing a ROM on that one should be a piece of cake.
 
Yes those instructions should work. Although I'm not sure what the best recovery is for the international version. I have the Sprint version and use Philz advanced CWM recovery.
 
Cheers guys well I have gone ahead and put cynaegmod ressurection remix on the s3 and installed gapps so working but have noticed if I try playing a game it crashes then when I reload it works and if I'm online I get a unexpected error crash message come up and flicker continuously for about a minute.

I have read online there are different gapps shall I try a different one or slim I think it is called.

I don't know why it would do this also how would I go around trivial things such as being able to put a background image on the text messages and battery percentage?

I am doing it for my brother and he has seen my s5 running lollipop and to be honest it looks different to what my lollipop interface looks like.
 
Your S5 has touchwiz, which is a UI layer Samsung put on top of lollipop. What you're seeing now is what lollipop really looks like.

Try a different gapps package or a different ROM. A lot of custom Roms have bugs unfortunately.

I've had a look and can find a rom that looks like the S5 but is running jellybean. So that will be left. Where can I get a different gapps package from and when I do it I just have to install the gapps not the whole rom again. Atm the only real issues are keep in getting this unexpected error relating to emails that flickers about 15 times then freezes the phone. And occasionally it not letting me send messages out. I think I will try a different gapps and if that don't help will have to try another rom.

Cm remix has cm theme engine. You can also get a cm 12 theme from the play store to change appearance. There is a galaxy s6 theme that looks great. Also a cm12 touchwiz theme that is based on the s5.
Yeah your s5 has Samsung's version of lollipop, the one on that s3 now (cm remix) looks the way google intended lollipop to look.
