Unlocking Galaxy S2 - AT&T Samsung Galaxy S II SGH-I777

Hi All,
I am a newbie...I would appreciate if someone could help me.
I am planning to root my phone using following,

If I use that root can I use following to unlock?

much appreciate your help

Rooting and unlocking the phone will not conflict. You can do both.
If you try the rooting method you posted, assuming you are still straight stock, it will not work for you. I suggest you either use the rooting method in the sticky post in the general forum, or if you are concerned about incrementing the flash counter, use the stock + root method posted by Entropy512. See the Guide "How to flash custom binaries..." linked in my signature for that.

what are the disadvantages of incrementing the flash counter? I would like to follow an easy method since I am new to this whole thing....used to be iphone customer for long.
appreciate your help.

There is quite a bit of information in the discussion portion of the first two guides. Some people are very cautious about possibly having their warranty voided, since in the agreement with the carrier, flashing custom binaries voids the warranty. On the other hand, many people are very cavalier about it, even returning their phones with custom software still installed. I have not seen anyone post that they actually had their warranty denied. I have been reading both the captivate forums and these forums for about a year and a half.

Thanks. So could I use the second method of not increasing the counter and use the kernel from this below?

Thanks in advance

Thanks I successfully rooted without increasing flash counter and also flashed the CWM....Yeeee....first timer here so happy. Now I have to unlock but I am really scared it will mess things up. Creepy could you please let me know if I could use the unlock method I mentioned will work?
Thanks.

Congrats on rooting, that method in your post works for unlocking. On step 2, just remember to wait. Your phone will be unlocked after it reboots. So if it says the application is not responding, click "wait"

Thanks all....
I did unlock it and also....flashed the unnammed. Very cool. I read everything like 5 times and followed everything to a letter.
Only difference was in the Android SDK...adb.exe is not in the tools anymore it is moved to platform-tools. That is where now you have to copy the zImage as the commands in the instruction assumes that adb is in the same dir.
Thanks.

Changed the wording in the Guide to make it clear. Thanks.

For unlock codes visit:

Why would anybody pay for an S2 unlock code when you can install a program from the Market for free?

'cuz they don't know free tool is avail., i guess.

Well if you google unlock s2 to find one of the various unlock code websites, you should see the app as well. its actually the first result. hope nobody pays for a code

If I'm not mistaken, you're not allowed to advertise for paid services in these forums. There's a marketplace on here I think for this.

Best Way to Root

Ok, I'm sure there is an identical thread, but after scanning for over an hour I can't find any clear answer to my question (Even the sticky has multiple ways to do it with over 500 pages). Each thread and article I read contradicts the last one, stating that this is the best way to root, or this is the best way to root and that the last one I read doesn't work well. Some of them involve flashing with Odin, some are similar to SuperOneClick, and then there is SuperOneClick. I've read that with some updates that this doesn't work and that doesn't work, but then I read conflicting comments and threads that say it did work with this update.
So my question is: what is the easiest, more reversible way to root? I had a really bad experience rooting with my first GSII (had issues with software and then it wouldn't call and then wouldn't unroot and go back to stock) and would really prefer not to flash if possible.
I'm running stock 2.3.4 (for some reason my phone tells me I'm up to date), and I do apologize if I'm restating a question that's already been asked a million times.
Look at the sticky. Will tell you everything
Where's the ban hammer?
Just follow the stickied instructions. There's multiple ways but they all lead to the same thing. A rooted phone.
P.s. I believe entropy has a good thread.

Are they all as easily reversible?
Sorry guys for posting an obvious question.
The best way to root for you is to follow my guide "Installing custom binaries without incrementing the flash counter" (See link in signature)
Follow steps 1 and 2c. That will give you root. It's easy to reverse. Just flash the stock package without root.
If you want custom software, continue on with steps 3 and 4.

This is the route I decided to go with. I had my eyes set on trying out the ICScreweD Rom along with the Siyahkernel but I couldn't get them both to work together using this method for root. I don't know if its just a problem that I'm having or that its just plain out not possible. I'm a noob still so I wouldn't know. I'm currently looking into other root methods so that I can use the Rom and Kernel I mentioned together.
However, using this root method was really simple to use and I recommend it.
The "next generation" scares me because they cant seem to do anything for themselves, always wanting people to do everything for them and they are so impatient.
Thread closed due to several stickys explaining step by step on how to root.

Can't get into recovery mode in Rom Manager

I experienced issue when using Rom Manager Premium 1.0.7. In fact, when I want to go to recovery mode from the application to backup my current rom, the app automatically asks me to make a title for the backup. After that I continue, it shuts my device and restarts it and it says Failed to Boot 2 and Starting RSD Mode... and it stays there for few minutes and I assume that it is frozen then I pulled the battery out and restart the phone. It boots normally, so I try it again but every time when I give a try it does the same thing. What can I do?
I am using a rooted Atrix 4G with stock Gingerbread ROM 2.3.4 and the CWM recovery is already flashed before attempting to do the above procedures.
There's also a thing that bothers me, my Atrix is an unlocked phone (it is not those that is on contracted, "locked', with the carrier) and rooted, but I've hear some people saying that even your device is unlocked and rooted, that does not guarantee that the bootloader is also unlocked, especially with the Motorola devices. Am I corrected or is this the case?

PLEASE HELP!!!
Don't bother with rom manager. Its a crappy app that most times doesn't work. Besides which, it sounds like you are bootloader locked, which means you can't use a custom recovery until you unlock it. Best place to start is searching for the unlock thread, then you can begin to utilize fastboot to get a proper recovery and ultimately a custom rom if you choose.
I saw online that many people unlock their bootloader by using Command Prompt on their computer which I do not like since I am not good in computer language and entering codes. Any suggestion for a easy way to unlock the bootloader such as an application similar to Superoneclick for rooting [slightly complicated one is also accepted as long as no command prompt or computer language are involved]? Thanks.
The unlock method by using what you call "computer codes" is as simple as it gets. It's just a few commands. I don't think anybody is going to bother making a clickable GUI frontend for such a trivial task. I think your best bet is to just follow the procedure and quit being scared of "computer codes".

What he says is true. Until my atrix (had backflip and flipside previously) I only used one click root. Once I got the atrix, one clicks didn't work, so I just CAREFULLY followed instructions to root and eventually unlock 2 atrixes and I dislike codes as much as you. Its all in how much you read read read. Its well worth it to do so.

I also hear people say that Motorola put a code on Droid X that when you want to unlock your bootloader it will "permanently" brick your phone and you can not turn it on again. But I am not sure that if they do the same on Atrix or maybe some guys already crack it since this is not a news. Do anyone here has the same experience like this?
Hm. Seems to me you developed an irrational fear of all this due to an information overload, even though much of that information doesn't even apply here.
Do you think there would be a clear and detailed tutorial (which countless people followed successfully already) if this was really so risky?
Put some trust into our devs here, will ya? Nothing can go wrong so long as you follow the instructions PRECISELY and take necessary precautions (if a tutorial says to do a backup, you do it).

Sorry about that, but unlike those of you who are in the game for years, right now I just got ONE (1) Android phone (and I just got XDA last night) so I can not get any error when doing these tweaks. Maybe I should slow myself down a bit and wait until Christmas after I got my Huawei Ascend D1 Quad to hack my Atrix. You know, it's like playing poker.
Oh yes. You should definitely not jump the gun and do something before you're ready. Do read and learn and educate yourself before you take any actions. Just keep in mind that this is not as complicated as it may seem.

So so true. So many people automatically panic at one minor thing (anyone who has unlocked their bootloader knows what I mean ) but if the tutorial is followed TO THE LETTER that minor thing is not an issue. Good luck and yes educate yourself.

Simple advice: read more! The questions you ask are all very basic and have been answered in depth on this forum. It is really important you understand what you are doing before proceeding further since Asus in their wisdom have adopted a policy which makes their devices particularly easy to brick.
It is a very good thing you are on ICS so whether you find it difficult or not your first step must be to understand and implement NVFlash. This is your insurance policy and you really should go no further without it .
Why exactly did you unlock your Prime? What was the limitation or the roadblock that you ran into that unlocking solved?

Actually, I saw that. I was a little curious about specifics. Among the countless threads of folks bricking their Primes, it's amusing to read a justification of "to make it great".
I partially unlocked in order to replace the stock ROM with one that didn't have a gimped download manager. The default download manager will give a fake error and then actively delete the file upon completing any .APK (yes, it judges on the extension) download from a website that doesn't give it specific headers, which is used to stop people from pirating apps via common file sharing sites (which are not set to give these headers)... but also stops a lot of normal android dev page downloads from working as well (for example emulator programs not available in the market).
Previously I needed to download things with Opera (which has it's own download manager and thus doesn't pass files to the stock one) in order to get around this anti-piracy code, but that's just a chore. After swapping ROMs, I haven't had that happen (though the ROM I swapped to forgot to remove similar protection on bluetooth files, which I'm going to report now as soon as I get 10 damn posts).
Also when I updated to Jelly Bean, I lost root (Voodoo root keeper was used but it failed, read around to see I'm not the only one that had the root backup wiped out when doing the official Jelly Bean upgrade), and so far unlocking in order to be able to flash custom updates is the only way to regain it.
Anyways the OP will want to install some recovery.flash thing like TWRP so they can flash their own files to the ROM, like the su binary, which is needed to root.

S3 adb reboot recovery & download mode

As I'm planning to root I was going through some of the root methods and I found this one(Link: ) which I would like to follow. I have two little questions to ask you who is knowledgeable.
1. Can I use adb to reboot into recovery or download mode instead of all those button patterns? which I don't personally like to do.
2. Why in the above mentioned tutorial at last it is mentioned to remove yellow triangle, is it necessary to do just after the root or can it be done while unrooting?
Thanks in advance for you reply.
Please don't say to read stickies and all, I had already read it

1) The commands should be: "adb reboot download" and "adb reboot recovery" (just googled... :highfive
2) If you don't get the triangle or if you don't care about it, you can leave it as long as you don't want to send in your device for repair

I'm not sure which statements you mean because you forgot to add the link in your OP.
But, standard manufacturer policy is (and I like many others find this totally unjustified) if you root the device your warranty is gone. You SHOULD be able to unroot it so that the guys at sammy never find out you had rooted once but that's something no dev or anyone else can and will guarantee you. Therefore the "standard" disclaimer on every ROM thread.
I for one rooted my S3 (my first EVER smartphone btw) about 7 months after purchase, never had serious problems and would never go without root again. It's just too damn awesome

Root for the Verizon V10 possible(Not ROM installation, just root)?

Hi guys,
Just wondering if I can get root without unlocking the bootloader. Seems that I;m hearing that this isn't possible, which makes no sense. I know Verizon is Verizon when it comes to locking things down(They were even blocking free games on dumbphones back in the day so that you would have to buy them, even when the manufacturer included them for free), but it seems that gaining root access is completely different than flashing a new ROM. Am I correct here?
Also, would towelroot work for this phone? I know it's a nice simple solution, but I believe their claim is for phones manufactured before Jun '14.
Lastly, would a solution like Safestrap work here? It's what I used on my last phone (S3), when Verizon locked THAT down.
I know it is a battle fighting Verizon on this, and I know it takes time, I was just wondering if I am reading this right, or if I could root, but run the standard ROM, just with the extra access... Really, the phone is working so well that I just want better control for things like deleting/disabling/freezing stock apps and such.
Thanks for any help!! Sorry if this is in the wrong thread, seemed appropriate.

I think root injection may be the answer.

I think that you may try it and it may work, as the above problem may not due to the phone but my computer.
Where did you get you system.img file? if you are using the one from the g4 it will not work. The file needs to be rooted for your device and then injected.

I'm curious, the 'Fail' just means that it fails to work, right? Phone works fine after that and all? No bricking or need to restore? If so, that's a safe risk. Thanks for the suggestion.

Good luck with this but I have a feeling that unless someone has an exploit laying around, you'll need an unlocked bootloader.

I think if LG release a genuine ROM file, we could replace recovery parition with rooted one and flash it to our phone, that the only way open but LG hasn't released any ROM file yet.
