I my self am also new to this. Rooting allows you to do a lot of stuff though. From roms to themes etc. As far as USB connectivity goes...you need to go into your settings..click applications...and click development..then select the debug option..thar will allow you to access your files and what not. If you have any more questions, pm me and ill share with you some knowledge I have gained from my friend who has been helping me along

thanks! that worked. i was about to be very upset about that lol. i guess i just may need to try another ROM. i wanted to make my phone more customizable. this ROM isnt showing me any different settings than i already have. any suggestions on that?

Have you found, as you tried various ROMs, whether the Sammy Touchwiz functionality was affected or disabled? Too, are you using your S2's hotspot/wifi tether feature, and if so did you merely delete or freeze the tether mgr and use the native tethering enabler, or are you using one which is builtin to the ROM?

Edit

does anyone know why the Unnamed ROM drains the battery so fast? my phone wont even charge now. or its charging very slowly

Problem with clockwork recovery

So i did the first couple steps in these directions and it seemed to work fine. But, when i go into clockwork recovery none of the menu items are clickable. Or rather, clicking on any of the options (reboot system now, install zip from sdcard, etc.) just brings me to a black screen with the CWM logo in the middle...I don't really know where to go from here.

from the op of this thread:

(to navigate cwm vol up moves cursor up and vol down moves cursor down. Home button selects and back button goes to previous menu.)

annnddd I'm stupid. Sorry about that, on autopilot from doing it so many times with my captivate...on which the power button was select. my bad, thanks.

Problems with CM Recovery

So I'm trying flash CM7 and having some trouble with it, mainly with CW Recovery (im assuming it is causing many of my other problems) When i reboot into recovery, either through ROM manager or the three button way, I get a black screen with the little android guy and a white triangle with an exclamation point in it. Only when I press the power button and this point does the standard CW Recovery option screen come up.

Then, at the bottom of that screen it says:

"CWM-based Recovery v5.0.2.3
Finding update package...
Opening update package...
Verifying update package...
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted"

That's not normal. And, whenever I try to flash a ROM, either from the sdcard or downloading one through ROM manager it fails. I'm assuming the two are related. How should I get around this?

Hopefully somebody will come up with a Root for the stock kernel soon....any ETA ?

 

[Cheaptrix]

Fantastic! Another satisfied user here.

 

[wastingaeons]

Thanks, this made a new user's life so much easier!

doesn't 2a in this thread point to the rooted stock?

So I've had my i777 for about a month now, and am becoming interested in rooting my phone. I'm currently in the process of doing the recommended research into rooting seeing as this is my first smartphone and I have absolutely no experience with rooting or linux. I have a few questions which I'm sure have been answered somewhere in this forum in some form, so I apologize if my questions have been answered, but I'm not good at piecing together information from various sources, plus I'm not so sure what information is fact or opinion.

Researching rooting I've come across some guides which look simple enough, however I would like to know exactly what I'm doing so if something goes wrong I can better troubleshoot it. So if someone wouldn't mind bearing with me and helping me through the process via PM, IM, or even in this thread, that would be much appreciated.

I understand rooting gains the user "root" access to the OS which gives the user certain abilities otherwise not possible. However I do not understand(even after some research) the process of "flashing". I am basically interested in freezing certain apps and removing bloatware to increase battery life, and am also interested in creating a backup.

Right now I have the following:
Model Number: SAMSUNG-SGH-I777
Android version: 2.3.4
Baseband version: I777UCKH7
Kernel version: 2.6.35.7
Build number: GINGERBREAD.UCKH7

I have downloaded Kies and updated to the latest version(2.1.0.11095_121), however on the main screen it says "Your device does not support software upgrading via Kies" and has the Current firmware version as "I777UCKH7/I777ATTKH7/I777UCKH7/I777UCKH7" is this normal for an unrooted device?

What exactly is the difference between rooting and flashing a custom ROM? I am under the impression that rooting doesn't actually change any firmware, but rather just grants the user "root" access, however it seems you must flash a ROM in order to root, I don't really want to change anything yet other than gaining "root" access. However I'm open to anything that improves my phone, stability is the most important thing to me...my phone is working perfectly ATM so I want to make sure that rooting and flashing or whatever isn't going to likely screw anything up(I know there are always risks involved, but that's the case with anything).

Thanks in advance for the help I'm sure you guys will provide, the android community seems awesome from what I've read on these forums as well as on the Android Forums.

USB Jig

For your yellow triangle issue just get or make a USB jig. It will reset your counter zero. You can get one on Amazon, Ebay, our xda market forum. Or you can get diy instructions just google "diy USB jig".



Hey davy, is this whole USB Jig thing that simple?!!? I've been hearing so much about this now, and I am curious to see if removing the yellow triangle is as easy as just plugging the JIG into the phone and "magically" everything is back to "stock" looking at start-up?....

Or am I missing something?.....

Thanks in advance

Rooting means adding superuser.apk, which is an application that manages root access, and a library of utilities to work with it. That is basically all that is done to root a phone.

Flashing means changing the actual firmware on the phone.

However, to root on the SGS II you must also flash.

I would suggest that you follow step 2a in the guide "How to Flash Custom Binaries Without Ever Incrementing the Flash counter!!" See link in my signature. (If you don't have a windows computer, then follow step 2b.) This will flash rooted stock firmware onto your phone. Once completed, your phone will be the same as it is now, plus it will have root access. If that is all you want, just ignore all the other steps. Of course, if you read the whole guide, you will learn a little more about your phone.

Yes, it's that simple.

 

[RocketSled]

Yes, it's that simple.

As I can attest.

Got my new GS2 last Tuesday. Rooted via Kernel-mod that night. As expected, got a Yellow Triangle. Looked up on the web to see what a Jig "was". Easy enough to make one, all that's needed is a 300K resistor, a spare male micro USB plug, and maybe 10 minutes of prep and soldering. But being lazy, if I were to "make", I'd probably have one of the Techs at work do it for me. Actually, I'm super lazy. "Order with one click" on Amazon. $2. Sure I had to wait 4 days for it to show up, but I think I only rebooted once that entire time anyway so it didn't matter.

It took longer to get the thing out of the package it came in, than to actually use it to reset the counter and get rid of the triangle...

Strong recommend "just buy a Jig".

Thanks for the explanation very helpful, is this stock ROM like official from Samsung? How is it different from my current ROM?

[Jonnyredcorn]

Also, what exactly happens when you flash? Do your settings and all your data(audio, pictures, etc) erased?
