Noob Questions Ahoy! - Galaxy S III Q&A, Help & Troubleshooting

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,

[Q] Rooted without making a note of my original version

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 .

[Q] N00b looking for advice

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.

help with my new s2

i am from galaxy mini forum so get a galaxy s2 but how to know if it is S2 or S2 GT-i9100 o and what the diffirence?? and can you gays pleas link me to a tut aboug instaling costome recovery, which ODIN to use and so on .... last thing which is the best stable rom to use .....thanks in advance
1) Check the sticker on the phone chassis under the battery.
2) Differences between SGS2 variants ? Wikipedia.
3) Just about everything you need to know to get you started is in the Stickies.
4) There's no such thing as the "best stable rom to use". There are a heap of custom roms for the SGS2, it's an individual preference thing. And because no two people use their phone the same way or have it setup the same, and because component-wise no two phones come out of the factory exactly the same, your experience with a particular rom will most likely vary from mine.
The best thing to do is to get your phone rooted, preferably with CWM installed. This will enable you to backup, restore & flash roms/kernels in a matter of minutes. You can than try a bunch of roms for yourself. If you find you don't like a rom you try, it's easy to go back to your previous setup easily by restoring a backup; recommended regularly/before you flash anything to your phone.
ok so by flashing cwm and then a costom rom the divise will root by it self and do i have to flash a stock ics rom to install a costom ics rom??????
Lackchoo,
Flash one of Chainfire's kernels. His instructions are very clear. That will give you root and CWM, and possibly also a yellow triangle at startup which you shouldn't worry about at all.
You don't need to flash a stock ICS ROM to flash a custom ROM. After rooted, in CWM, just install the downloaded ZIP ROM file of the custom ROM. You will keep root and triangle will go away.
Ditto what the above person said about ROM's. However, you can try Cyanogen (Do a 'stable' release, not a 'nightly'), its the most 'popular' ROM in terms of numbers. One can't and shouldn't say which one is best. But for a newbie, I think Cyanogen is a good place to start. Perhaps it will give you the least issues and the most 'oohs!' for your initial newbie effort
I don't have the links with me from the smart phone, but just search 'chainfire kernel root galaxy s2' and 'cyanogen galaxy s2' and you should find the relevant thread. Read it slowly and repeatedly! I know I had to

Installing wrong ROM. HELP

Hi,I rooted my phone then I installed new ROM but then, I installed Galaxy S2 I9100 JB ROM Which was I9100XXLSJ ROM
when I have Galaxy S2 SGH-i777. I know I'm stupid I didn't read it clearly it just said Galaxy S2 Jellybean
I have factory reset it but it is still the i9100 JB ROM not my old AT&T version
I used Odin3 v1.85 to do all this. I have downloaded several ROMs to see if it worked but when I opened them up it dont work with Odin and they said something about installing with SD card and stuff. I tried and i cant find the program and such.
At this moment I I just want my phone to work again. It don't matter if I use stock version of ICS as long it works again with ATT. because right now. my Back/Search doesn't work and Calling.
Please help, and give good explanations because I'm not very strong in electronics
If your phone will still enter download mode you can still fix it. Look through the stickies(important threads which have been given special status due to their importance and relevance) there are several that explain how to return to stock firmware. You should probably flash a full version of stock including the bootloaders as what you flashed may have contained I9100 bootloaders. But better safe than sorry. I've given you enough information to get started, let us know how it turns out.

[Q] Only S2 (Intl.)-ROMs on the S2 (Intl.)?

Hey guys
I am using this ROM on my S2 (Intl.) and yeah it has some bugs, but thats okay, but today i saw in the CM download section that there is CM11 available for the S2, butonly for the T-Mobile version.
So my question is, whether I can flash the T-Mobile version or if that would brick my phone. And if I can't, can I flash ROMs from the Note 2 for example? I have one S2 in use and one only for testing ROMs, so i could copy a stable S2 ROM on my sd and then copy the CM11 T-Mobile, too. Then I'll flash the T-Mobile ROM and if that wouldn't work i can boot in recovery, clear all data and flash the stable version? Or is thisimpossible and I am just a silly dude?
thanks for answering
Merry Christmas!
Do not flash non-I9100 firmware on the I9100, yes, there's a fair chance you'll brick your phone if you do.
I suggest you learn 'the basics' given your question (read the guides/tutorials stickied in the General section for starters), 'messing' with your phone in any way (particularly if it involves flashing, even with CWM) is risky without knowing them.
no no I know the basics including that you should not flash not appropriate firmwares, it was just a question, but okay, I understood, so I#ll keep waiting until an official version of CM11 for the normal S2 will be uploaded

Exactly. I know it seems a madness that the Galaxy S2 has not yet been updated (it is enough to think that the Galaxy S already has the CM11), but more of install the CM11 not journal cannot we do.
P. S: Merry Christmas
