Firmware update, how to, where and what? - Galaxy S III Q&A, Help & Troubleshooting

Hi,
I apologize in advance for this question.
I'm new to this flash thing.
So first of:
Is updating the firmware to the latest one a good idea in general?
How do I find out what firmware I have?
How do I find the firmware I need?
Where do I still find firmware for these old phones?
Are there any benefits for updating all this before I attempt to install a custom rom and / or a custom kernel?
How do I actually make a full backup of everything if there ever might occur an error or mishap?
(Must guides I find online are awfully outdated or suggest software that may not actually work)
Thanks in advance
Sincerely
Julian

[Q] Quick question with flashing ROMs

So last night I rooted my Samsung Galaxy S2 and I’ve got a few questions regarding various things that I havn’t been able to find through searching around on the forums. If the answers are around the forums and I have missed them I apologize and hopefully you can direct me there.
1. Since I used chainfires rooting method. I’ve used Nitrality’s app to ‘backup’ my /efs and something else it backup up. Here I’m wondering if I use a custom rom such as “Lite'ning Rom v6.1 XXKH3” will the things I backed up with Nitrality app restore my original ROM and Kernel incase something hardware wise fails and I need to send it back in to claim on my warranty.
2. The second question im asking is regarding various Custom roms, if I choose to flash ;Lite’ning rom, will I be able to since it states it’s;
based on I9100XXKH3 firmware
baseband I9100XXKH3
The baseband I’m using is XWKE7, will I be able to use this rom?
3. since the version of android I have is 2.3.3 and majority of the Roms need 2.3.4 will it work correctly? If not and I have to legitly update to 2.3.4 will it successfully update since i've rooted my phone?
Hopefully you guys can help answer my questions. Thanks.
bump because I really need help :[
- Litening ROM is based on KH3 ROM, that doesn't mean you need to have a Stock KH3 ROM. So yes, you can install it.
- As I said it doesn't matter what ROM you currently have to flash a 2.3.4 ROM.
- Don't know about the Back up issue, sorry.

thankyou so much for your help
before I flash it will I need to upgrade my 2.3.3 to 2.3.4 though?

[Q] Help w/ installing mod/Kernel on stock N1

Hi all,
First of all, apologies for a very newbie question.
I have a stock N1 with terrible battery life. I have stumbled intersectRaven's mod/Kernel at: http://forum.xda-developers.com/showthread.php?t=653598
I would like to ask how I can install this on my N1, is it just a matter of downloading the right file, renaming it to update.zip and then doing what I've done to update my phone as with official updates?
What do I need to pay attention to and is there a way to revert back to the original rom/Kernel if I'm having issues with this mod or if I want to sell my phone?
Thank you in advance!
You should have the clockworkmod on it. its the easiest way to install kernels. just have the kernel on your phone and click the "install rom from phone" button in the app and it should do the rest for you. I recommend backing up your phone. i never wipe when installing kernels always when doing roms though. Also a good idea is to look for the stock rom for your phone before doing anything to it so you can return it to factory. Goodluck!
Thanks merrick,
I will do some more research regarding the clockworkmod and see if that does the trick!

[Q] Updating Custom ROM via Built-in Software Update

I have searched for this simple question, but have yet to find an answer.
I have a custom Android 4.2.2 ROM (for my SGH-I337M) (I cannot provide a link as this is my first post) and I have received a notification asking me to update to the latest version on Android (4.3). I would, but I'm not sure if it is safe to do so via this method. The main reason I have not done this is because after installing this ROM, my model number changed for SGH-I337M to GT-i9505. By doing this, my reasoning is that the update downloaded is for the GT-i9505 and may not be compatible.
Now for the question, is it safe to update my phone this way?
The main reason I'm not using the Android 4.3 link is that my Mobile Network State will not change from Disconnected in that ROM.
While I'm at it I may as well ask this. If I do update this way, and it doesn't work, would a simply recovery from TWRP be OK?
Thanks in advance, and my apologies if I have posted this in the wrong section, I could not find one that was specific to my issue.

[Q] Help Clarify The Difference Between The Two - ROM & Firmware

First of all, I'd like to thank you for taking time to look at my post.
This may be a very simple question, but I'm a newbie and confused by what's being said anywhere on the Web about these two - ROM and Firmware. I've just rooted my device and have been reading a few articles on what to do next with a rooted Android phone. There are posts and videos about updating a device with a custom ROM or updating the Firmware. I'm wondering what those are exactly and what their differences are.
Thanks.

generally both r same stock android software is called firmware also called stock rom

Firmware names?

This is a list of firmware files for vince. Can anyone tell me which firmware relates to which part of the device? Thanks in advance.
U don't need to unpack the zip, flash it only in the recovery
Thank you for the answer but I already know how to flash. I just wanted to know which file is which firmware. For example one of them is probably the baseband/modem but I don't know which one it is. I want to learn all of them but specifically the one that deals with the touch system may be enough. My phone has a weird touch issue. Touch rarely stops working for a few seconds. This is a used phone and It was same in the latest stock rom and continues doing so in a custom rom. It's not that annoying but I'm gonna try downgrading that firmware if there is any in that archive file. I hope it's not a hardware issue.

Answer with short Google
Latest baseband?
Hi guys, I'm still using the first oreo baseband (from 8.4.27 rom), has there been any new one with the recently released MIUI 10 developer roms? If yes, could someone be so kind and upload it for me? Thanks in advance!
