I recently shifted to an android from an iphone and I am loving the experience. Unfortunately the noob I am, I didnt do my research properly and I went ahead and rooted my Samsung Galaxy S2 without making a note of which version my phone was (i.e KE1, KG3 etc etc). Now I want to shift back from Lightning ROM to the original Samsung Sense but I dont know how as I dont know which rom or kernel to download. Could you help me out. I dont have a clue of what needs to be done. Also what do I need to do to un-root my device if I ever require to do so in future.
I would be grateful and in debt to you if you could help me out.
Samsung dont have Sense .
Product code on the box or under the battery may give an indication of original firmware otherwise its guesswork .
Question was phone branded was phone from a particular area .
Stock rom post has many Samsung roms Branded rom post likewise .

Stock rom flashed via Odin will remove root then reset custom rom counter via USB jig .

First Of all I would like to thank anyone who helps me in advance.
Just received my new galaxy s2 (around 30 minutes ago). Allready I want to root the device. Although i'm looking for a point in the right direction on the following.
a)the easiest guide to rooting
b)I'm after a stock (most up to date rom) if possible as my is currently filled with bloat ware (thanks to three UK). Coming from a Nexus s which was my first android phone I'm not used to this neither do I like it. So is the a way to flash a stock rom so the phone is like it would be if I brought it sim free and unlocked.
Currently not looking at any other gains, for the time being at least although im sure the flashing roms bug will catch me.
Old phone was a Nexus s as previously stated which was rooted with CWM installed.
Also I can't believe how busy these forums are! Makes the Nexus scene look dead!

Rooting means voiding warranty.
Wouldn't you want to try out the phone and stress test it a little under a valid warranty before you start messing with it?
I was under the impression I could just unroot the device?
Also that stock rom I was linked to will that get rid of the bloat ware?

You can just unroot it, yes. Unfortunately, a lot of the "bloatware" is Samsung, not your carrier, so you're stuck with it (unless you read up on what you can safely get rid of). If you're looking at flashing an up-to-date firmware anyway, why not consider an AOSP ROM. It's the closest thing you'll get to a Nexus build and they're about as bare-bones as you can get!
If you are interested in that, here's a link for one...

There are others, but I can only speak about that one personally because that's the only AOSP one I used before I went MIUI.

Yes you can unroot. But every time you flash an unofficial kernel(to root), you increase the custom binary counter. Samsung will know that you have been rooted before even if you reinstall the firmware and kernel. USB Jig's reset the counter, but don't upgrade to the latest firmware(KI3) that hasn't been modified to include the old bootloader. The new firmware fixes the USB Jig counter reset.

Trust me it's is the best rooting guide for noobs. When I rooted my device that was the only guide I could trust, because it was a step by step guide. Read it carefully, if you got any problems you can pm me and I'll help you. If you post in the thread you'll get help also but you have to reach 10 post to post in that thread.
EDIT: I also found a video that shows the same method from the thread I gave you.
http://galaxys2root.com/galaxy-s2-root/how-to-root-galaxy-s2/
Just in case you need visual support. But you should read the thread carefully anyway.
Thanks for the link to the video, rooting looks really easy although I'm abit sceptical about rooting at the moment due to them knowing if you have previously rooted I thought they wouldn't be able to tell.
Also things look very complicated when compared to the nexus s the galaxy s2 seems to have hundreds of different codes, firmware versions ect.
All I'm after at the moment is just get rid of the Three branding and bloat ware.
A lot more reading ahead I think!
Been doing a little reading and I think the branding is the CSC? Can I just flash the XEU file for 2.3.4 (my current version) to get rid of three's branding? If so would this void my warranty?

Samsung stock roms do not void Samsung warranty though they may or may not void Threes warranty .
Rooting or custom roms void warranty .

I'm not to fussed about rooting at them moment I just want to change my csc and upgrade to 2.3.5 which I believe is the latest version. Doing this won't void my Samsung warranty? If so I'm going to have a go.
Also will flashing wipe any data?
Thanks in advance.
I read a few guides regarding rooting and I'm still sort confused by some aspects of it which still eludes me.
I have a UK T-mobile S2 which is brand new and while I adored this phone and happy I got this over the 4S. The one aspect I'm not too keen on was the amount of bloatware which this devices comes with.
So using this guide here:
http://reviews.cnet.co.uk/mobile-phones/how-to-root-your-samsung-galaxy-s2-50004972/
1. However, what kernel do I need for it? So many to choose from?
2.I like Touchwiz and I want to keep it however, is there a rom to get rid of all the bloatware that I don't need like T-mobile recommend apps. I'm not sure what rom I need or do I need something else?
3.Unrooting is possible since I may need to send it back to Samsung since there's a screen problem which isn't major but I don't want to send it straight back at the moment.
Thank you for your patience, and help.
just install the right one from here

then use cwm app to make a back up of your current branded rom. Then either download titanium backup form market and use it to uninstall any apps you dont want on there or flash the non branded rom for t-mobile from here

Hi there guys I really need educating. I come from a Samsung Galaxy S to a Samsung Galaxy S 3. I know all about firmware flashing, kernels n stuff on the original Sammy G, but haven't a clue on the Samsung Galaxy S 3.
I have managed to root the bad boy (go me!) but am unsure how to carrier unlock and to flash the latest firmware. The Sammy G was carrier unlocked but my Sammy G S3 is locked to Vodafone
Can anyone point me to the files and maybe some guides so that I can procede? Also what is this business about a flash counter? I want to be able to return to original firmware if it all goes belly up! How do I backup my original firmware?
Many Thanks In Advance
Doozy,
P.S.
Who is the best Dev to follow for A) Rom and B) Kernel? I followed CyanogenMod on the Sammy G but the CM9 nightlies fpr the Samsung Galaxy S 3 seem a little immature for me at the moment.
Cheers once again
I think you don't have to backup your original firmware because you can download the stock firmwares again later, but you can do a nandroid backup (i never did this^^)
If something goes wrong, follow this guide: http://forum.xda-developers.com/showthread.php?t=1671969
About unlocking i don't know, but i think the lock will be gone if you flash any rom (but can't give you warranty, since my phone was unlocked)
You can reset the flash counter, it's called triangle away : http://forum.xda-developers.com/showthread.php?t=1494114
Im not able to say, whick rom / kernel is best, but why don't you check this thread and try some roms? http://forum.xda-developers.com/showthread.php?t=1674286
The first CM9 releases had many bugs, but they seem to be ready for all day use now (but i missed the Sammy Camera App, which is very nice )
Thank You very much for taking the time to respond I will take a look at those links.
Thanks Very Much,
Doozy
I have been digging around trying to find a straight answer. My understanding is that the J120a is simply an AT&T-branded J3. Is this correct? If so, can the J120a successfully run custom ROMS designed for the J3? I like the phone, and it was inexpensive, but the bloatware is frustrating. I have read lots of forum posts regarding rooting this phone, but rather than simply deleting the bloatware after rooting it, it figured it would be much better to flash to a ROM that doesn't have all that garbage (Like the factory Samsung ROM).
Thank you in advance and I apologize if this is a redundant question.
