[Q] Upgrading ROMs - Galaxy S II Q&A, Help & Troubleshooting

I understand there are several threads of the same name, but a brief check on those threads tells me they are on to subject matters different from mine.
In both a case of curiosity, I went to flash a ROM on my SGS. It's the Lite'ning ROM, by the way. It was only after I did that that questions started coming up.
What will happen when I can upgrade to a newer Android firmware (say for example, 2.4?) Will it be possible to upgrade to that newer firmware and undo the ROM like how it is with the iPhone?
Also, I'd like to know whether there are any specific procedures involved in upgrading the ROMs that is flashed on the phone. Do I simply grab the latest version of the ROM and flash it as I did the first time?
Thanks in advance. Hope to receive responses soon.

Reading is your friend.
I voided my warranty and your mum.

NO you will have to wait for Litenings upgrade or remove it from phone .
Also, I'd like to know whether there are any specific procedures involved in upgrading the ROMs that is flashed on the phone. Do I simply grab the latest version of the ROM and flash it as I did the first time?
Yes simple rule is follow the written instructions for each rom .
But that should be preceded by reading the FAQS and understanding what you are doing first .Otherwise you join the list of i broke my phone due to not following the instructions posters .

New to I9100, couple of questions.

Hi everyone, I bought a galaxy s 2 I9100 from somebody Nd the phone is great. It is already rooted however it doesn't have clockworkmod recovery installed. How do I install it on my phone? And when I do can I install any I9100 rom or does it have to match my kernel version XWKDD? Thanks sorry I'm a noobie to this phone
The easiest way to get it is to flash Chainfire's CF-Root kernel.
But, just a word of advice: don't flash anything until you read and understand the basic procedures for flashing a ROM or kernel, etc., because it's NOT that difficult to understand, but you can mess up your phone by doing dumb things, most of which are already covered here. So, give yourself some time to absorb the basics before jumping in and getting yourself in trouble.

Ah, well, then you should be fine. The basics are the same for all the S2 variants. Just know not to flash any of the G series ROMs (and avoid Re-Partition in Odin) and you are all set.
Like I mentioned, it's not that complicated, as you apparently already know, but almost every time problems arise, it's from following advice from another forum, at least from what I've observed anyway. They'll say something about "I followed this guide...." and include a link to a four year old post in some other forum about the wrong model or something and act stunned when they brick their device because they followed the bad advice.

I'd suggest you start with a stock ROM, such as the latest KK5 and use the CF-Root kernel (as in my signature). You could always venture into custom ROM territory later, after you get a feel for it.
I tend to gravitate toward stock experience myself, and I love JKay's mod which works well with stock ROMs, but there are some terrific custom ROMs here to choose from, if you feel so inclined.

How to root and 'best' ROM

I'm a noob who needs to learn how to root their sgs2. First Android phone but I'm looking to open up and get more from my phone.
Also there seems to be so many roms and people taking of bricking. If anyone could explain the 'best' rom and what to do once my phone is rooted I would appreciate it thanks

If you don't know what you want root for, I'd suggest not rooting.
The best ROM is <insert name of ROM here>.
My advice: stick to stock.
Man, people need to use the search button nowadays :/
As well as Google.
If you're an Android noob and you start rooting, there is a high chance of failing to root HENCE a brick would occur. Most bricks you hear or see that people get are from careless actions or they don't know what in god's name they are doing.
Do not make that mistake.
Research before attempting because I assume no matter what, you want your device rooted.
Make sure you have an GT-I9100 device, check by turning on and off your device.
The best ROMs I have used, and maybe you should stick to for a while, is either CriskeloROM, SensatioN Rom, CheckROM or Lite'ning ROM, found here: http://forum.xda-developers.com/showthread.php?t=1253665
Use Odin to flash a custom kernel, for example Ninphetamine: http://forum.xda-developers.com/showthread.php?t=1179814
Follow guides on ROM pages to install their ROMs, installing a ROM automatically roots your device.
Good advice from previous poster.First read up on rooting and what it brings to your phone as it doesnt just bring flashing rights.As for bricking,its easy to brick your phone if your not carefull and dont read the instructions well and put the wrong kernel in Odin.Its an easy proccess but some people just dont follow the guides.Bricking in some cases is self caused.The ROM thing is a hard one cos there is no perfect ROM when everyone has different needs so its a case of read each ROM thread and choose what you like.If you dont like it try another.No one here on this site who knows what they are doing,Im quite sure,has only ever flashed one ROM in there time here.Best thing to do right now is stay stock until you read up on some important facts about flashing
1.Rooting,how why and what it brings.
2.nandroid backup
3.EFS/IMEI backup and restore-super impotant cos if you loose this info your screwed
4.the difference between each one and what each Dev brings to his/her ROM
5.Flashing.Some are done via recovery and some via odin.Also bootloops and how to get out of them
if i were you i'd first read all bout roms/kernels till your eyes bleed
then once you know how to do it, well pick a kernel and a rom which suits your needs
learn from people mistakes, i usually read couple pages on how people messed up while flashing so i dont fall in the same, and in case you brick your phone also have a way to recover it prepared
Maxwell0;2109742
Also there seems to be so many roms and people taking of bricking. If anyone could explain the 'best' rom and what to do once my phone is rooted I would appreciate it thanks :)
As asked if you know nothing and that knowledge is so limited you have to ask the banned question what is best rom then stick with stock until you understand .
Likewise why root if you dont know why .

Why don't you take time and search all is posted it's not that hard..
yea, when i got my phone i used stock for a while until after a while i decided to root and flash different ROMs. was really scared and overwhelmed by all the info on XDA at first, but after reading everything over and over again , bookmarked tons of links i picked up the courage to root and started flashing ROMS.

[Q] custom roms for SGS2

hey have any of you guys installed a custom roms on the SGS2 i have the phone rooted and i was contimplating installing a custom rom just wanted you guys information on how safe it is to do so. I was acutally looking for a nice ICS custom rom but apparently i would need one for my kernel(XWKL1). What would happen if i install a custom rom of ICS ment for a different kernel would it brick my phone?
thanks in advance for any information.

probably but you are better off reading and learning before bricking your phone
ICS is yet to be released but we do have a buggy leaked ICS test rom you need to know how to recover before flashing .

Yes it is safe if you know what you're doing and for you that means don't go anywhere near an ICS ROM try a Gingerbread ROM first but before you do that read and read and search and search.
Just practising my speed typing....
wow thanks for such a quick reply so for example if i were to install the Omega rom i would need to get one for my kernel version only right? Then if would need to revert all i need to do is flash my old insecure kernel back and i would be back.
edit: - i didnt see B3311 post. ok i am a lil confused now if i were to install a custom rom ment for a differnt kernel would it work or would i brick my phone?
Kernel version doesen't matter.

Search, Read, Backup and try. Everything you need to know is in the threads. Please read friend that is the only way you get to learn. Look at me. Been reading upon the threads once i had my galaxy s2 just before xmas and i have read upon two months before i got my phone. Now even though i only joined recently i know near enough what i need to do regarding as rooting and flashing roms and themes go. But i still search whenever i can for what i need before i have to ask questions. And most of the time it is right there infront of you. Also another thing if you think the search engine is crap on xda use google. Most of the times it gives you what you are looking for.
Not having a go but today mininum have been two three threads what rom is the best and what one to use and so on. Anyway good luck with the flashing and hope you enjoy whatever you choose

True but even with all the reading at least you will feel more comfortable about going about and rooting the phone and flashing a rom. That way at least you do not have to expect others to spoonfeed the information to you. Also when you flash a rom for the first time you will feel great about yourself cause you did it all by yourself than asking others to help you. Hope that makes sense.. and to what you said also you have a great point and i always read your posts when you help people JJe as you are one helpful guy.
Hey, I just contacted Google and advised them to remove the Google search widget that comes standard on every android phone's home screen.
It useless I told them, nobody seems to even notice or use it. Heck, why search when you can just ask?
Still waiting for there reply.

to be clear i never asked which rom was the best and which one to use. I have been reading up on all the different roms available i have narrowed it down to the ICS and the Omega rom and i know how to flash the roms the instructions there are quite clear my only query was about the kernel version for which i could not find a solution. Now i have another question since you guys are saying the kernel version does not matter then why are they country specific and suppose i use a kernel ment for USA would that mean when ics finally got released here for the sgs2 i would need to reflash my phone with the gingerbread 2.3.6 version before i could get the official ICS update from kies?

let me make this clear. Different variants of the s2 hence why you see different forums. If you have an international version then you are safe to flash whatever you want in this forum here. So if you see USA version I would steer clear it as it has nothing to do with the international version if that makes sense. Regarding your other question well yes flash BBL to stock official ROM and that is it

The kernal is not related to country or carrier. The csc is.
Practically all custom roms come with working kernals and modems for the rom.
As for getting the official upgrade, you can reflash your original firmware, but most here just download the new official firmwares from the Intratech thread or sites like sammobile and flash it with Odin. No need for kies. I don't use it at all except for when I first got the S1 in 2010.

Since the device isn't mine and the owner tried to upgrade using kies but never got it through due to slow download in kies.

Well firstly please do not use silly topic titles such as this. This is a questions forum, you have no need to put your topic title as "have questions" that's a given and doesnt give anybody browsing forum any info. Topic titles are supposed to be descriptive of topic and it baffles me why so many people find that concept hard. You will get more views and potential help by giving brief description of topic instead of generic crap.
And as already stated, use the inbuilt system update.

There is no need to worry about that crap. Its just n00bs who have other stuff running in background that interfere with flashing or they low battery etc.
Just install latest Kies to get drivers and flash via ODIN according to guides here, making sure not to use any .pit file or repartition etc.

[Q] Android version

Hey guys ! Today I got my International GT-I9300 and I have android 4.1.2 on it. My question is that is there any newer version from Samsung since I don't want to void my warranty by flashing a custom rom. If there is one how do I update it and if isn't any new one are the dates know when Samsung will give them out ?

no, there isnt, sorry. If you wait a while they may release a 4.2 (or maybe 4.3) touchwiz rom, but for now you have 2 options, use that rom, or use a custom rom.
There is really nothing to worry about with flashing roms, just make sure you make a nandroid backup beforehand, the only way to truly brick your phone is to be extremely stupid and flash a rom or kernel meant for a different device.
If you need to bring your phone in, just restore the nandroid backup and reset the flash counter.
Hmm, that's some weird advise you've given there.
Anyway, 4.3 official Samsung rom has been out for a few days now -head over to general forum to read the stickies on how to use odin and the official firmware thread to download the file.
You can hard brick your phone simply by ticking the wrong box in odin, so be very careful and follow the instructions exactly.

really, samsung kies doesnt have it, well at least where i live.
well that is true that you can tick the wrong box and brick, but, like flashing the wrong file, you'd have to be stupid when all the tutorials say that it bricks your device.
Simply .4.3 is rolling out officially at some stage you will get the update via Kies or OTA .
At XDA we have a couple of 4.3 firmwares that can be flashed .
But that would require you to read the faqs and guides first .
Plus the updates really have to many problems to bother with wait for later versions .

Neat rom lite 4.3 is working very well for what I need, no bugs at all (apart from the wake delay, but it's always done that to some extent).
I agree with JJEgan 4.3 update is rolling out but it is.... well how can I put this nicely the "update is not what we expected" because you don't want to root and flash custom roms I suggest you wait and read up about the new "update" if that's what it isBut at the end of the day it is your device and if you do go down the custom rom route read read read!
I have the I9300XXEMG4. So can I use this guide to get to 4.3 ? BTW the guy at 9:32 the guy says that by flashing the firmware his counter didn't go up is that true ?
http://www.youtube.com/watch?v=rs_sg7UxpoE
4.3 is due to roll out for the international s3 anytime now depending on your carrier, I wouldn't go through the trouble of flashing firmware if you dont know what you're doing , I am due 4.3 in a couple weeks according to three
