Hi there,
Today I received my Samsung Galaxy S2 and now I'm trying to find some information about custom roms for my phone. After searching through all sticky's here I cannot find any info about where to start with custom roms.
My previous phone was a HTC HD2. I've installed android onto my phone using MAGLDR and Clockworkmod, which worked great. The thing I liked the most was that in case I screwed up a installation I could alway flash the original Windows Mobile ROM back, making my phone almost stock again(still will have to remove HSPL then).
I also helped a friend install custom roms on his HTC Desire HD, but the thing I notest on that phone was that you could never go back to the original android installation. I hope this is different with my new phone.
So these are my questions:
- Where can I find some information about flashing a new ROM to my phone?
- And is there a way to revert back to the original ROM after using a custom ROM?
Grtz Willem

First root your device.
Then:
Flash a rom which you can find in the Development section. Every big rom has their installation procedure explained. (VillainRom, Cognition.. dunno)

You can just flash back the original stock rom, but there's a hidden counter that counts how many times you flashed new software. You need a little tool called a 'usb-jig' to completely undo the number the counter is on. This way you'll retain your warranty.

How?
Clockworkmod? If so, where can I find the ROM?

Nope, with Odin. You can find the Programm and the rom together with instructions on www samfirmware com
Thanks everyone, I'm downloading the original rom now, then will try my first custom rom for the SGS2 (VillainROM 3.0.0)

hello all,
Before I being, i searched a bit in this forum and in web. But the questions i have still are not answered.
I on KE2 stock ROM. i have an unbranded SGSII. I have rooted using steps mentioned here http://forum.xda-developers.com/showthread.php?t=1125414
I want to install any of the custom Roms or the newer ROMS mainly because the battery usage sucks. with some hour music and calls battery get drained easily.
I dont mind updating to latest stock ROM also as long as it solves the problem.
Kies dose not offer me an upgrade and its also grayed out for some reason
Here is my SGSII specs
Code:
Product Code: GT-I9100LKADBT (From RegEdit)
PDA: I9100XWKE2
Phone: I9100XXKDJ
CSC: I9100OXXKE2
Baseband: I9100XXKDJ
If I have some problem, I want to revert back to Stock rom before giving it to Samsung. I have also ordered a USB Jig. It should be on the way now. So i can reset the counter as well.
Before flashing, I want to know what all i should do. Is it just fine If i flash the firmware file? Also in Samfirmware i see something called pit files.
can anyone help me in flashing the correct rom?
thank you
All Custom ROM's give detailed installation instructions in the first couple of posts.
For what it's worth, having tried a number of different ROM's, VillainRom 1.4 has the best battery for me. 2 days with moderate use.
+ Villian rom but read and understand the instructions before you start .

Cognition S2 is a good rom, full instructions for flashing.
If you look in the android development section, theres also a thread with all stock firmwares, kernals and tutorials for flashing
thank you all.
I was wondering about how to revert back in case of some problem. Also do I need to take care something about the baseband etc?
I am kind of new so thats what makes me tensed! I dont want to screw up the mobile.
Don't worry, once you have USB jib, you can reset Odin flash counter and this is a safe way to rescue you in case of brick.
In terms of baseband, ke4 or kf2 are the best ones. Kf2 kernel + kf2 base band is a good combination. You can try many ones and choose by yourself.
On xda, there are all stock firmware to rollback if needed.
Take a look at the stock rom and branded roms post in Dev section find your phone and download a copy of the rom.
That can be flashed back via Odin to original state wiping any root and stock roms .

How about ROM Manager ? i read that It can install ROMS over air
http://www.androlib.com/android.application.com-koushikdutta-rommanager-nptD.aspx
Don't use that as far as know. My kernel wasn't supported and it took me days before my recovery mode was working as I wanted. Maybe it works with other kernels, but with my bad experience thus far I don't install that again.

Please dont install rom manager. Its not fully compatible with the sgs2. Use it, and youll be back here asking for advice on how to fix another mess.

Installing rom manager is not an issue... Very few custom rom are compatible with this. Afaik Cognition rom is one of them.

You think I can install ROMS with this? no more Odin?
No this is a little bit more complicated. You need a rom compatible with this like cognition seemed to add. The main idea is to have a rom compatible with rom manager and this will allow you to change to another rom compatible with this. Unfortunately, there are not so many custom rom... Perhaps sicopat's one?
I justed wanted to say that rom manager is not dangerous to install and even to launch.
OK Thank you,
But I am still confused If i need to update the modem etc. Let me do some more search
You can upgrade modem version by Odin flash mode separately to the rest.
http://forum.xda-developers.com/showthread.php?t=1131950
Just download a modem.bin file or gets it from a complete firmware by unzip.
Put modem.bin into phone area of Odin and start accordingly of normal flash processing.
Thanks bgn9000
MY whole worry is whether to update modem or not. I dont want to mess with my phone as i think there is no downgrade.
Looks like I have to invest more time in understanding this flashing
Im new to the whole SGS2 so needed a little help ive rooted my Galaxy and its on UK 2.3.5 stock rom my question is can i flash any rom i choose or is it like when rooting it when i had to get a kernel that matched.
The other thing is, is it worth buying Odin Mobile.
Cheers
Once you root your phone and have CWM recovery and not the stock one you can flash any ROM you choose.It has nothing to do with kernels but each ROM is based on a firmware so you should match your firmware to a ROM based on the same to start with and if you choose to stay with the same ROM then there are non-wipe ROMs that can be flashed over top without worries.Just be sure you read properly the install/flash instructions.Some ROMs need Odin to be flashed but most just need to be pasted to your internal-SD and then flashed in recovery mode.Ill leave a link below to my ROM where there is an instruction guide so you can read it to see what I mean.

It depends on how you have rooted ...... if as mentioned above you have CWM (means you have flashed a custom/insecure stock kernel) just flash a ROM with CWM Recovery like any ZIP but i'd advise you to reset the phone before that .... since you are on Stock ROM which is Odexed and all custom ROMs are deodexed you might end up in a bootloop also may i suggest CheckROM as it is simple to install and highly customizable thus i recommend this as your first flash......
checkrom thread:

else i use this site it's pretty awesome to keep track of things

Cheers to both of you, i think i will give checkrom ago as theres that many to choose from and im new to the rooted SGS2.
hi guys,
i'm new here so i don't know how everything works,so i could use some help.. i've recently rooted my phone using CF-ROOT 5.0 XWKJ1 and i'm a bit confused what to do now.. i wan't my phone to run on newest stock firmware, which one should I use ? the most recent one in intratech thread is XWLA4 (phone is XXKI4,just like mine,so it is for my phone or what does it mean? ), can I just flash it to the phone ? can i do it through CWManager app ? and i still don't entirely understand the difference between Kernel and ROM, I'd also like to try the cyanogen mod,what should I do first ? and how can I flash back original stock rom ? because cyanogen is 100mb and original rom is 8, so I'm not sure if it will restore the phone to the stock state after flashing stock rom back.. and yes, I've read the guide to GalaxyS2 and Android,but still do not understand everything..
thank you guys for your effort.

You need to start reading the guides your questions are all answered in the relevant guides .
You want CM you follow the instructions for CM you want xxx you follow the instructions .
ROM is firmware kernel is part of the firmware that interfaces OS and Hardware .
But suggestion is to wait for release of ICS .

Take time out to read the guides as it'll help you out.
XDA is a development forum and requires leg work!
Not only that it'll stop you joining the many others in "I haz a brick"

Hey guys
Sorry for the noob question but I want to double check something before I accidentally brick my phone.
I rooted my phone and flashed the Resurrection Remix ICS 9.7 rom and have had a play with it for a few days and want to go back to stock.
It's using a custom kernel and obviously custom rom.
To flash it back to stock using Odin, how do I get a stock official ICS kernel for an official ICS rom (such as one that you download directly from the Samsung server using CheckFus)? Also does anyone know of a guide that specifies exactly how to do this?
Thanks
You can extract the kernel (zImage) from the rom tarball you download via Checkfus with any program that allows you to work with tars (IZarc, 7Zip, WinRar, etc). No guide necessary, easy as. Open the tar file with said program, find the zImage, extract it. Done.

Need ROM to roll back to
Just got a i9100 with 2.3.4:
PDA:I9100XWKH4
Phone/Baseband (modem): I9100XXKH3
CSC: I9100OXXKH2
I don't find this rom on the roms page, and I understand I need it to be on my PC ready to flash with Odin, in case by flash to 2.3.6 doesn't work out (that's the only way to roll back, right?)
Where can I find this rom?
Thanks!
hi guys,
i have a samsung galaxy s2 (GT-i9100 - NFC), which i got from orange end of 2011. I the in jan 2012 got help from this forum to root my phone and change the rom from the original to:-
Rom & Build No: VillianROM 3.0
And' ver: 2.3.5
Baseband: i9100XXki1
Kernel: 2.6.35.11-ninphetamine-2.0.5+ninpo @ titan #20
Although the phone works okay, i'm beginning to notice a lot of slowdowns and regular reboots, so i want to go back to whatever latest google android OS the S2 can handle (rooted). I've forgotten what to do and would be most grateful if someone could please help me with the following:-
1. Whats the best software/method to backup everything?
2. What is the latest rom (original, but should not have a provider's bloatware) i can use on the S2?
3. Once backed up, how do i change from VillianRom to the latest/best OS currently available?
4. How can i root the original rom?
Thanks once again

For official stock rom, check
www.sammobile.com
And search latest stock rom for your region.
If you like custom rom, then there are so many roms on xda. I like omega and alliance roms. Choice varies from person to person

1. Depends. You can do a backup in CWM to image your device or you can use Titanium Backup Pro to just backup your apps/appdata and restore to new rom.
2. http://www.sammobile.com/firmware/ < Check your device/model here.
3. Well just so you're clear, There is no "best" its subjective. Also "latest" depends on what type of rom you want to flash like Sammy/AOSP/AOKP/CM/MIUI etc. To flash latest samsung do it via ODIN, to flash any other do it via CWM. All info you need is already on forum.
4. By flashing custom kernel via ODIN.
All your questions have already been answered countless times.
Thanks very much guys. I simply want a fast lean rom as some seem to be slow running.
Doesn't get better than this.
sendign the phone for warranty?
you will need to flash back the original rom and unroot your phone.
if they found your phone is rooted the warranty void, experience it before so be aware of this.
Let me thank you guys for advicing me. I am most grateful. I read your posts a bit late and in the meantime, I think i have bricked my phone as i've flashed Samsung's original FW (I9100PBVLP8_I9100PORALP8_ORA) from sammobile.com. I used Odin v3 and successfully flashed the phone, but it's simply stuck on the boot logo. I have even done the following:-
I've managed to wipe the cache partition, but the recovery menu has No advanced options. It says:-
ANDROID SYSTEM RECOVERY <3a>
reboot system now
apply update from ext' storage
wipe data/factory reset
wipe cache partition
apply update from cache
test redband fota[FS]
But i still cannot get it to boot. I have also tried to use an old nandroid.md5 backup i made, but odin reports the file as invalid.
I'm desperate guys, please could someone help me.
Download Mode and re flash.
Are you sure you are flashing the right ROM right? Check under the battery to see the Device Model.
If it's i9100, then make sure you are downloading a i9100 ROM.
Thanks very much for your advice gastonw - i have managed to fix the problem now by going into system recovery and doing a factory reset, so thank you.
Although everything seems to be working fine, i would have preferred a more newer 4.2 jelly bean rather than 4.0.3. Oh well beggars can't be choosers and all that, lol! I guess i'll have to re-root it again.
gastonw mate ur a star! I've installed the latest JB rom u posted earlier and i'm very happy with it.
Now before i damage it beyond repair, how do i root it safely?

Hi You could try this method http://forum.xda-developers.com/showthread.php?t=1501719 its quite safe so ether should work or wont, if don't no harm done as it doesn't need a insecure kernel.
I'm quite new myself @ this so plz use caution when trying it out.

Good to know man, enjoy it
About root, I've seen a couple of methods laying around the threads, I'm sure they're safe.
I still think that ExynosAbuse app is the fastest way to Root now (one-click).
Here's a vid. I never tried it tho.
Thanks very much for the links AnubuRe and Gastonw.
Gastonw mate, i have been playing with the rom you posted a link to. Don't get me wrong, it's great and very fast, but the downside is that it doesn't have a huge number of options to tweak etc. Now someone mentioned a rom called Neatrom, but i'm wondering what you can recommend? I don't want a bloated rom...i want a fast rom, but with some options to allow me more greater control over the phone.
Also, i know this is a bit off-topic, but can you recommend me a widget app, where i can quickly dial phone numbers i.e. by touching a person's photo?
