T-mobile Samsung galaxy S2 Rooting help! - Upgrading, Modifying and Unlocking

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)

1 click root w-framaroot. Got mine on Play store.

[Q] Should My Battery Go Down This Fast ???

Hi,
Yesterday I bought an HTC One X and over-night it was charging and when I took it of charge at 11.30an to go out to my nearest costa to meet some friends. I was just surfing the internet, facebook and answering a few texts. Come 1.45pm my battery was down at 19%. Im just wondering if it should go down that quickly. I know One Xs have 1800maH batteries which is bad as I was used to a Note II but sadly had to sell it.
The phone is very nice, screen is great but battery lets it down. Any ideas ????
Thank god Costa had charging sockets haha!
Thanks
if you bought the device brand new then it's unusual, if it's used, unlocked and running some custom rom and kernel (which, when you ask a question like that you have to specify in your OP) then it's likely that you need to flash a different kernel. On another note there could be a hardware issue, battery or cpu, does it get hot or laggy?
My battery today all on 3G. Brightness Dim. Insercoin. Can't complain.

Hi,
My phone is used but only 6 months old and I contacted HTC and they said a cache partition to reset it or something so will give that a try.
Thanks Guys
Here is a couple of things I'd do and you'll be able to see exactly whats happening.
First:
Download an app called "Wake Lock Detector" from the playstore. HERE
Second:
Download BetterBatteryStats HERE
Have some normal use for a day or two, let it settle etc, then at the end of the day CHECK BOTH apps and see what comes on top.
You'll be able to see which apps / services are draining battery, if it is apps using a lot then remove them unless important.
If apps don't seem to add up to the amount your using, it could be a battery or your voltage limits.
Hope this helps.

vbus-tuna_otg wakelock

Hi everyone before hand I want to thank you for taking your time to help me, with that being said let me get to the point.
I have a Verizon Galaxy Nexus 32GB that I bought used, about 2 months ago. When I bought it, it had an unlocked boot loader and I installed TWRP 2.6.3.0 Recovery and CM 10.1.3 Stable. Since day 1 the battery life has been bad and the screen constantly turns on to the lockscreen.
I reinstalled CM 10.1.3 with the 08-12-13 GApps, I checked the checksum on both files and they are good. I have bought a new battery and I changed out the USB port flex cable that comes with the usb port and the problem is still here. The main wake lock that shows up on Better Battery Stats is vbus-tuna_otg and its been killing my battery like crazy, sometimes about 98% of my battery drain is because of vbus-tuna_otg. So if you guys could give me any tips or hopefully help me fix it I would greatly appreciate it, thanks.
Tried battery change and port replacement too. It didn't work. It's a board issue. Maybe if there was a way to remove some code from the framework to disable this process. It needs deep knowledge of the code and probably a developer to help , if something like this is possible without breaking important functionality of the phone.

[Q] Possible inscresing battery life & performance?

Hello everyone, I am new to this forum , my first thread here , so be nice , etc.
My first touch phone was a Samsung Galaxy SII back in 2011, that the phone was working perfectly until I saw all the themes on the web , downgrades , upgrades and such. I accidentally kill my unit twice, So I had to file it for $ 35 I think. Today, I can not charge it at all, in the hole where you insert the end of the charger for it to start charging , where loose it. It may fall out out cell phone at any time , so it 's no use I use ODIN anymore.
The third time I killed my Galaxy S2 I bought the Galaxy Nexus the day after, I was so happy, it's the theme I always wanted and blah blah.
But after almost 7-8 months, it slowly ........... Slow responding when typing , slow to open applications , lagging on any games that should not be .
So I decided to downgrade to Gingerbread 2.3.5 for maximum longevity takes less on device performance.
BUT ! I do not do it directly on my Nexus , since I dont want to take the risk to kill it, so I wanted to downgrade my galaxy S2 from 4.1.2 to 2.3.5 , becase I do not even care about the phone.
And my galaxy lose few perfect for a few minutes without using it , so the charge would be pointless .
My GF also has her own GS2 , and we charge my battery with hers phone that way.
now days i dont care about the theme or design, just a performance, and the delay is my enemy.
But any idea?
My nexus is really slow, and I want to increase the battery life ..
And i am not sure that i want to do a wipe data, wipe cache..
And i have another question, on my galaxy, i have no fastboot, how can i install it? I've doing huge research and stuff, if anyone know alot of this stuff, phones, firmwires and such, please, could we take this private @ skype or anything you like.
my skype is muspru @Skype
Beucase i can have my help much easier from there.
I am having a headache trying to read your thread....
So what exactly are you trying to do? downgrade gnex to GB?
if thats what you are trying to do, i would recommend against it, the phone come with ICS, and you can upgrade it to 4.3 via OTA, it is MUCH faster than ICS judging from personal experience.
If you want to save battery, simply flash a custom kernel and UC/UV it, i didnt even UC/UV, using fancy kernel / CM 10.2 rom, and my battery doesnt even take a hit when idling, unplug 7am everyday, and i have around 100-99% around noon.

LG G3 Slight Lag

Hi Guys,
I am really new to this forum and I deeply apologise if this thread or subject matter has been opened numerous times.
However, I am just somewhat really puzzled as to how amazing the spec this phone is. I just loving it apart from two things. The battery could be better but hey with all that juice and cpu it needs to run that beast of a screen its understandable. However, the ultimate thing that bugs me is how it gets incredibly laggy at times when hoping from an app back into the home screen.. Especially in games or Facebook.. Has anyone experienced this issue?
I have rooted my LG g3 too and I have also turned the developer options on in which I have decreased the transition times from the default settings to off or 0.5 for few of the minimise options..
I just hoping anyone can help or have ideas?
Thanks so much
By no means am I trying to be rude, but if you search around a bit, you will see that this is apparently an issue just about everyone has.

There are 2 theories. 1 is that the software isn't optimized and is causing lag. 2. It takes more resources to draw the QHD display, therefore the phones CPU and GPU is having to work harder than an HD display and this is causing lag.

I couldnt agree more in regards to the QHD screen. I just hope that can flash Stock Android on to the device or just install something that is different.
Apparently I heard there was rumours that the screen could be decreased to 1080p?
Instead of crying, just got to the hidden menu and enable 60fps in the dynamic lcd refresh menu.

People here get mad if you don't use the search efficiently. It's actually one of the forum rules.
If people do get mad, realise that they've probably seen this question 2343636 times and you maybe could have found it. Just move on.

That's the stupidest thing I've heard. I own a Nexus 10, a two year old tablet with the same resolution as our G3. It has a dual core processor, running 1,7Ghz. And guess what, it is smooth as hell. Even smoother than my G3, like a lot. And I don't like it... But once the bootloader gets unlocked we could probably see the G3 running flawlessly with Android L.

I am sorry to disappoint but some people are not as fortunate to have the intelligence that other have and as life has evolved, so will my knowledge as time goes by in having my phone...
I have been a LG G3 user for month and 2 weeks so far. First android phone. From an avid iPhone 4 user since it came out...
I'd greatly appreciate if people could respect me and help me rather than slate me for my 'noob' questions...
Other than that thanks to everyone who has shared light with me and who can continue to provide amazing advice.
After boundless and endless search, i have after hours of tedious trail and error managed to flash the leaked firmware 10j that i see floating about on the forum on my D855 and noticed a slight decrease in lag.. I have also changed the runtime from Dalvik to ART.. Which made a slight increase in speeds...
Aside from that can anyone please give extra tips and personal tweaks they done to boost there performance?
Thank you ever so much!:good:

First I'd like to apologize for all the rude people around here. Sorry buddy.
Second there are many things you can do to make your phone faster and lag free.
I copied this from the post here to make it easier for you.
Open the dial pad, then type the following number, choose one code that matches with your device model:
- 3845#*855# (Intl)
- 3845#*851# (TMo)
- 3845#*850# (AT&T)
- 5689#*980# (Sprint)A hidden menu will be showing up, scroll down till you find “High Temperature Property”.Tap it, then*turn it ON.
Now find thermal daemon mitigation and turn it on either. switch off your phone, and wait for about 15 seconds.Next,*turn it on*again, when you see screen lock, wait at least 35 seconds.Enjoy your lag-free LG G3.
Third, I advice you to change the launcher. I suggest nova since it's full of customization and really light.
Here : https://play.google.com/store/apps/details?id=com.teslacoilsw.launcher
Install it play around with for a while. It's easy to customize it the way you like.
Enjoy your phone buddy...

Thanks ever so much for your amazing support and suggestions.
I have managed to do the sugggested list that you mentioned. I just realised a new issue with my phone that I really am surprised about now. I charge my phone at 100% and within 2 hours I have lost a good 30% of my battery within a space of 2 hours.. By having the phone on just locked.. All recent apps closed. Its a strange issue. I dont know why all of a sudden.. I can see in the battery menu that andriod os and android system are taken up about 47% and the display taking 35%...
Im sorry to branch from one issue to another but I dont really know what to do. And I am really worried in doing factory reset and losing my data. I am having to charge my phone in space of 2 times in a day.. doesnt make sense.
Thanks so much

Can you post a screen shot of your battery stats so we can see what's using the most battery? It could be a rogue process killing the battery.
There is probably some app eating your battery. Try to post a screenshot of you battery stats. To do so press power button and volume down at the same time and hold them for a second.
Any way, Apart from the battery issue, how's the smoothness?
As you can see in mine I'm off the battery for 3 hours. Haven't used the phone e so far since I'm home playing battlefield 4. Still at 100 %.
At first the battery drains a lot faster when in a new rom, the it settles.
But in your case it is draining way to fast.
Restart your phone, give it a full charge and let it rest for an hour. Let us know how it goes.
Thanks guys for your response, I am really shocked as to why my battery is just eating up soooo fast like that... You can see from the graph in the screenshot that it just plummets down sooo fast within hours..My screen brightness is set at 50% without no auto brightness and I don't really have much apps running.. Im really bemused as to whats going on?
I removed the battery for a while and I also restarted my phone.. This is a MASSIVE improvement because the Android OS and Android System was both taken up a good 40% and screen 30%.. but even with the stats shown I'm still reducing significant amount of battery..

[Q] Overheating 🔥?

I just got my Samsung Galaxy s6 edge white 32gb last night and I noticed that is over heating than it should be. I'm using it for Web browser and texting nothing that should cause to heat up. I also updated to the latest version.

Actually if it was overheating then the phone would automatically shut down to prevent damage, but yes the phone does get hot rather quickly. But I've had glass and aluminum phones before and they always get hot fast since metal retains heat.
Mine ran a lot hotter than a normal glass and metal phone, and it was laggy/jerky. I flashed the stock firmware to it, and now it's smooth and cool.
Here's How:

yes it does get hot once in every 3-4 days & when I say it means really hot..

Smart switch is not working for everyone. Hit or a miss thing.
My phone heats up to 44 C
What is the Warning Level is it safe till 45 or 50 Celsius ?
It happens when
1) On use of Google Maps while driving
2) Charging
3) When i use Sandisk OTG, to the extent that it stop the Transfer & freezes
4) Even if i Record Videos sometimes
5) While wireless charging
This is really bad Never had such a Issue
I agree with some of the sentiments here that the device can seemingly get pretty warm - especially when I tweaking things or using apps that use a lot of CPU or using the camera for too long. But I do believe a lot of it is related to the aluminum/glass case - I believe Samsung is basically taking advantage of the case as a though it were a heatsink - releasing all the heat into your hand/pocket/air.
This is truly the first phone i've had that manages to stay under 100° F even when cpu frequency is locked to the maximum and I'm playing very gpu-intensive games, provided that i'm not charging the battery and the phone is not in an unusually warm environmnt like a hot car. I should mention that i'm rooted and lots of preloaded software has been removed. I would download some sort of process monitor and check it to see if there's a misbehaving app to blame if this is happening regularly.

Hey,
I saw that you posted a solution when someone had problems with his S6 edge overheating. I've an S6 and I think I might have the same problem.
I was wondering if you could spare some time to help me. I posted my problem here. http://forum.xda-developers.com/galaxy-s6/help/help-s6-cpu-getting-hot-t3180011
I used Antatu benchmark and CPU temperature to test my phone and it got to 84.0 C twice, once when it was testing my CPU to it's fullest and once when it was testing game performance.
So I was wondering if you could run the test as well and tell me what temperature you got so I can compare. Thanks
I haven't tried your method yet but I will tomorrow.

For the record, mine just hit 85C while running AnTuTu. As far as daily use, it made a world of difference on my phone when I flashed the stock firmware the first time. The phone was terribly hot in my pocket when I was not doing anything, and it was SUPER laggy when I was. Not something I expected from this phone. After the flash, it was a Beast and ran MUCH cooler. It would get warm still when doing intensive tasks, but that would be expected from an Octa-core phone in my opinion. It does not get uncomfortably hot anymore, like it used to though. I would imagine it went WAY above 85C when it got hot before, because it was actually hard to hold at times.
If you have not flashed it since new, I would highly recommend it. I know it's a pain, but it's a one time thing that you never have to do again, and the benefit MIGHT be large. No guarantees, as you may not have the same issue, but I've received a lot of reports from people who have done it and they say it breathed new life into their phones. For me personally, it was DEFINITELY not a placebo affect. It was night and day.
With all that said, I've got my S6 Edge up for sale right now as I've moved to Apple for a little while. I continually jump around, and T-Mobile offered the iPhone 6 for $15/mo and I can trade it in 3 times in the next 18 months for free and keep paying $15/mo for the newest phone. I'm looking forward to seeing the difference in the iPhone 6s. If it sucks, I'll be trading it in shortly for another Android phone.
PS: AnTuTu final score: 69314!!!! Wow!!!
One more thing. To eliminate ALL lag and slowdown, I replaced the Samsung Launcher with the Google Launcher. What a difference that alone makes! Seriously, try that one thing. It's huge. The Samsung Launcher has some issue somewhere that they still need to address.

It should. As long as Smart Switch can recognize your phone model and download the Correct Firmware, the Flash WILL help the Heating and Lagging problem. If your phone is not recognized, then Smart Switch will not do anything. It's worth a try.
For me it happens especially when im playing arround with that samsung theme store build in app. I don't know why that app needs so much power to have that effect on the phone but for sure its something samsung needs to look at.
For sure they need to re-design that app from the scratch. Its like the "my first homepage" of theme apps.
