Underclocking and Unlocking - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Just took care of finally rooting my S2 LTE (Rogers).
The first two things I was hoping to do was under clock the CPU to help increase the battery life, as well as unlock the device itself.
I know there are some apps out there, like Set CPU, but just wondering what everyone was doing, if at all in terms of under clocking.
Also, does rooting help make unlocking easier? Or am I still going to have to shell out $30 on some unlocking site to get a code?

I answered your pm. Just letting you know.

Should I Root?

Please keep in mind I have never rooted a phone and have no idea how to.
Ok so I Don't know if I should root my Sensation, or just leave it as is. I know there are risks to rooting, but I hear rooting makes phone's more customizable?
So.. Please post:
-The Advantages of rooting
-The DisAdvantages
-The Risks
-For a noob like me, on a scale of 1-10 how hard will it be? 10 = Hardest
-Should I root, and why.
Thank you!
Go to google.com and type in "what is rooting android" now spend the next 30minutes-1hour reading and learning.

From a scale from 1-10, I think it'd be like a 2. Its fairly simple if you read the instructions carefully.

You should definitely root! It gives you complete control over your phone and customize it whatever way you want!
On a scale from 1-10, i think it'll be 2 too. Its really easy if you follow the instructions clearly.If you don't, there might be a chance of bricking your phone if you messed up somewhere badly. The chances are really slim though!

Root gives u absolute control over your phone. Like admin rights on a windows computer. No disadvantages. Lots of advantages (read: a lot of cool programs out there that require root privileges)
The risk is not following instructions and turning your phone into an expensive paperweight. For a noob like you, if you can follow instructions, difficulty level is a 1. Likelihood of you bricking your phone is negatively correlated with your SAT score.

Real question is:
Does the phone do what you want it to do as it is now?
If the answer is 'yes' then rooting isn't really neccessary. The ONLY reason I've rooted is to remove all the system apps I don't use. I use my own ROM which is basic and does what I want it to do

Prety much this ... for a noob rooting is totally useless .. many people do it to strip the phone off useless aps to make it faster ... which fact lost its point for me with new OTA release with which Sense became fast enought to prevent example me from bothering with rooting. At this moment theres no reason good enough for me to do it.
Another group of people are those who root just to be pimp and IN even if its totally worthless for them.
Different group of people are those who use root/s-off for changing/modifying/creating custom ROMs with either some sort of tweaked HTC Sense with transparency, various MODs and that kind of stuff, or totally different graphic layout (which reason i never fully understood since i bought Sensation for its Sense .. hence the HTC brand .. innit?)
So yea ask urself ... does the phone have all i need? if the answer is yes, then theres no need for rooting for you.
Thats my subjective point of view.
If you root you can customize your phone the way you like it, or atleast the ways developers make available to you. i just rooted my phone for the first time and it was way easier than i thought it was. before you flash a new rom, make sure you backup your device with titanium backup. then after its flashed, you can easily restore all your apps and data with titanium backup. the only data you really lose is your home screen apps because you have to put all your apps and widgets back on your own.

^^^This is THE perfect response to the question
I've not rooted and unless I need ICS and it won't come to the Sensation (to be honest, by the time you NEED ice cream sandwich the Sensation will likely be old tech) so I'll need a custom ROM, or there's some work related can't live without app that requires root, I can't see myself ever needing to do it.
I have rooted my 7 weeks old Sensation after only 3 weeks. Initially I thought I would never have to do so, but there were 2 things which made me unhappy: bloatware and the bitpool problem which causes crappy sound while listening to music over bluetooth headset. After all I flashed the device with as much as 7 separate roms and since today I'm happy with CM7 alpha 4. It's like a completely different device So I'd always say yes, but it depends on how your needs are.
You should root. Simply because there are many awesom apps in the market that required the root. With a rooted phone, you can do whatever you want.
The risk is your phone can be bricked. But i rooted many android phone but no brick to me, you should give it a try
What amazing apps are there for rooted devices? I'm thinking of rooting mine, mainly for the extra customisation options, but don't know if I can be bothered backing up all my apps and data. You have to back up sd card too don't you?

Titanium Backup
Root Explorer
AdFree
you can even install the HTC Beats Music mod, if you want to. I've tested that and it really sounds better. I even miss that on CM7, but I love CM7 for other reasons...
I'm sure, I forgot some apps, but it's late here
Regarding backup:
I usually have Titanium Backup for my apps & apps data (important and convenient, when moving to another rom) plus a general (clockworkmod) backup of the whole phone rom prior to flashing to be able to easily go back if something goes wrong...
im not stranger to rooting as i have done all kinds of crazy crap to my vibrant, i have the sensation and im not so sure if i want to root. Its cause i hear Htc devices are alot easier to brick, and i don't wanna risk messing with the bootloader. So far its running great, wifi tether, screenshots, i don't think you really need it.
well.
i thought im not happy with my phone so i rooted.
i installed the revolution room , it looked promising but im not happy.
my phone getting super hot while playing and some time rebooting it self and dont stop reboot until i remove the battery
as someone else said if u happy with your phone just leave it.

And if you're not happy with your phone send it back for a replacement
Course now you'll have to get it back to it's original condition and un-root it to do that...
And how about spoonfeeding???
Dude... Please read, read and read some more.
What ya'll get with root.... almost all access to all the files....
Here comes the question? What ya gonna do with it?
Do you need that?.... Don't think so. Yer probably thinking of supping yer phone...
Installing different ROM.... Then... ROMs come rooted already.
What you might ask for is: Should I S-OFF my phone?
That's up to you. You lose yer warranty if S-OFF discovered, but you can do whatever you want with yer phone....
Hope I explained as simple as it comes...

Mine doesn't. I've never had a reboot due to over heating, or gotten too hot to touch, and that's even with streaming music via bluetooth, downloading over 3G and using GPS. Likewise while playing graphics intensive games with online content it's got warm but not over heated.
Some handsets have suffered an over heating issue and rightly have been replaced under warranty.
You should root, really you don't know what your missing, Android Revolution is best ROM out there and root ting is vary safe.
OK I am also new to rooting.. Can anyone suggest me link on how to root my sensation.. Plus after rooting do I need to change Kernel and Radio? (Though I still don't understand both terms).
My only concern is the slow performance. The phone should run faster for a 1.2 Ghz processor...

[Q] Which AT&T capable LG G2 DOES NOT have carrier IQ?

I am on my next to last day to exchange. Let me say that I love this phone except for the fact that AT&T has Carrier IQ installed and it can not be removed without rooting (at least on the 2 year contract one). There is a process to stop it and it's not that hard, except that it is a PITA to do it every time you reboot. If you forget to force stop, you are in the clutches of Carrier IQ. Also, I have doubts that even though it is stopped via a forced stop, that it is not residing somewhere else on the phone and still doing the nasties that it was designed to do. There is no sense in going over CIQ as there are a couple of threads already on the subject in reference to this phone and AT&T.
Unfortunately, I am stuck with AT&T and carrier swapping is not an option so the only option open to me right now is the phone.
So, is there a version of the LG G2 that is available for sale in the US that can be used on the AT&T network that does not have CIQ installed on it? Maybe the full sale priced one that AT&T sells? Or maybe a different one from Best Buy or someplace else? In a nut shell. Looking for a LG G2 that I can use on the US AT&T network that does not have CIQ installed.
I am new to this "smart phone" game but really am impressed with this phone and want to keep it, but in reality, unless I root it and void my warranty, this CIQ issue could be a killer for me. The reason is because I used to work at that big glass building at Fort Meade and know more than I want to about electronic data mining and collection. BTW, AT&T (both on line and store front), LG tech rep (store front), and LG (on line) all say that CIQ is not removable in the version that I have without rooting.
Any options that I am missing?
I don't think you have any other options friend. I'm also in a similar boat of having to return it tomorrow if I choose to do so. I think the full price one, or the one from best buy would be the same as they're all at&t branded so i'm sure they are all part of the exact same batch. There wouldn't be anything different between them.
I think I'm going to go ahead and root and disable it. There is no other phone that I think is this good, period.
Short answer, no. Long answer, your only option would be to buy the International or maybe Korean variants online and at full price and slap an AT&T SIM in it. I'm pretty sure you wouldn't get LTE though.
I get the feeling this is not what you want to do, so if CIQ bothers you that much and you're not willing to root you're going to have to return it.
You might want to consider waiting for the Nexus 5, which will likely share at least some hardware characteristics of the G2.

Simple. Root. Easy and fixes the issue and more.
guys...its not that hard...just root it...install system tuner...disable 6 entries...done.
I have never rooted a phone. I do not know how or what is required. I am not computer illiterate so I think that this is something that I can do if I had instructions on how to do it. Where would I start to look for the process of rooting the phone?
What is required to do it?
Hate to loose the warranty on it but I guess that I can always return it to factory default (I think) if I had a problem in the future. I just like this phone too damned much to let it go.

You'll also want to read up on how to install and use ADB. There are some good guides out there that include videos.
The T-Mobile variant gives you the option of turning off CIQ. I was getting wakelocks from it, but since I've turned it off, it's been as quiet as a church mouse. Not sure if the radios are the same, I don't really know what AT&T uses.
Root it. And leave at&t as soon as it becomes an option because this won't be the last CIQ phone

Well, I read the links. It looks pretty straight forward. Bit confused on some things. On the phone, I can go directly to the "Developers Options" under the main menu and turn that function on or off at will. Why all the hum drum about going into the About Phone menu to the Software Version to hit it 8 to 10 times to get the Developers Options turned on? Also while watching the video on how to root it, I got a bit confused on the "shift right click, open a command window" at 2:08. I do not have that capability. Different OS maybe? Anyways, I can always get a command window through the Start Run menu.
If I root the phone, I know that I can restore it to it original stock based on the first sticky in this forum. However, someone indicated that even if you return it to stock, there will be indications that it was rooted. But I could not tell what version of the phone that he was referencing.
Do I/Should I back up anything first before I start? Not that much on the phone right now, just my Contacts, a couple of pictures, and some apps that I downloaded. Home screen setups and things like that.

Apparntly the VZW variant shows the phone as rooted in about phone. I went through every single menu on the T-Mobile variant and I see nothing to reference that I have rooted my phone.
Oh that was it? I had that turned off when I set up the phone. Lol Thanks
Ok, so once its rooted, what do I do? Where do I delete the files to get rid of carrier iq?
Custom rom; no carrieriq. Besides didn't they change it so it's not that big a deal anymore?

This is absolutely not listed in the Verizon version. Pretty sure the VS980 has CIQ too.

Or just flash a custom stock rom that is debloated and has modded options preinstalled.

Tmobile samsung Galaxy question. Possible rooting help too.

Hi I had some questions, that if the action can be done by rooting my phone i was wondering if someone can send me to a video or tell me them self step by step clearly how to root a phone and if needed a custom rom with detail enough that i wont brink my phone i would very much appreciate that.
First My phone seems when on the app store to download apps really slowly, i have factory reset my phone but still acts this way can anyone help me with this issue?
Also my battery life seems to be very bad i see my phone at 97 percent one moment the 80 the next. Is the only way to increase battery life is by power saver mode and limiting my cpu and setting my brightness to nothing? or are there better options out there?
Also I was told rooting my phone and using battery calibrate might help is that true?
I have the Samsung galaxy s2 with a 1.5 cpu from t-mobile running on 4.1.2.
P.s Any other information you might know about this that will help my phone for the better please also include seeing that i have never dealt with this phone. (also i know its kinda old but with college its the only thing that really fit my budget)
P.s.s i wrote this same post on the wrong section can someone tell me how i can delete it so this isnt considered as spam or anything, would be appreciated

which buil number :confused: ?

hi
i just bought this phone today and i am noob in huawei phones functions and wondering which build number is better in battery life,smooth scroling and camera?
i have stock frd-l09c185b385 and as my expriences on sony phones,android N has battery draining issue,heating problems and lag
in first gaming test with clash royale I face small lag when new trop deploying (just like xperia z4 andorid 7)
is it same in this phone?
and the other question :
should i open bootloader to root device is this build? ( i need my app data to restore)
thanks:fingers-crossed:
No, this phone does not lag at all unless u get a virus or whatsoever. The phone gets warm sometimes, but doesn't get too hot. There are no battery issues either, but the battery life with Marshmallow was a bit better. However, it is worth it to update it to nougat in the case you are wondering.

Do you mean go completely back to stock like you never modified the device.? If so yes it's really easy to do.:angel:
I have latest stock L09C432B389 build, no lags, no heatings problems and finally no battery draining like in previous builds.
But it seems to me , that EMUI 4.1 (Android 6.0) is still better battery optimized.
So if you need battery, stay at Android 6.0, for performance Android 7 is better.
Regarding to root, it's very to unlock bootloader and root this phone.Restore to stock is also very simple.
It's practically impossible to brick this device.

Load Nougat on Galaxy S6 - Worth it or will it kill it?

Don't hold back the details. I "need" (not want)... "need" to know if I put Nougat on the Galaxy S6 if it will just make it ridiculously slow and unusable or could it actually improve it?
I do not believe in putting new software on old hardware, for all devices, but I would really not like to hear "guesses" - but people who know from others who have done it or who have done it themselves.
I want to put the Samsung factory unlocked Nougat on the S6. I'm not asking for instructions on how. I just want to know if its worth it.
Thanks!!!!!

Ok I don’t use my s6 full time. In fact it’s become my backup. I did use my s6 on android N prior to upgrading and had no issues with it running it at all.
In fact I still power it up and play with it now as I will no doubt use it again and I believe it performs very well to this day. I’m sure battery life is an issue regardless of what os is running as the battery in the device itself isn’t big! But I’d have no doubt about putting android N on it again given the choice.

I'll say it in few words: the best version you'll ever use in your s6
Wow, even though just 2 replies, that makes me feel better. Thanks! I'll try to remember to post back here what happens after I do it. I will be needing to rebuild the phone too: New Battery, LCD and Camera... lol - I'm bothering because... well the phone has always done great. It "was" the best phone I've ever had, but now network updates are forcing me to move it into "current times" .
