There lot of interrogations and frustrations concerning slowdowns/battery drains on Android, sometimes not really fair.
You need to control your build and knowing what is going on into it, because most programs you install live from their own and can downgrade your stability and your battery performance.
A detailed guide is provided here in order to have a good battery drain with very smooth and reliable android experience on Hd2, gathering tips and advices users need to know when they come to this Os or want to improve it durably.
Following this guide, you will be able to have hundreds of apps into a super smooth, stable and battery friendly android build.
Most importantly, without transforming your smartphone into a dumbphone :
- Wifi and sync always on
- Mails checked every hour
- 148 applications installed (no I don’t need them all ;-) )
- 6 widgets running on the screen or in background (check screenshot) : Folder organizer, News, Facebook, Current widget, Powersnap, switch pro, pure calendar, pure grid calendar.
- In standby, it can last for 4 days :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
- Smartphones are more and more looking like a laptop, so I consider that 5 or 6 hours with the screen alight is good.
The assumption is the battery drain can be affected by several factors:
1) Screen brightness.
2) Memory management if wrongly configured
3) Program launching in background if wrongly configured
4) Program updating in background if wrongly configured
5) Build and Kernel
6) Wm rom, radio, Sd card, Cpu in standby
7) Extras : Backups, customizing etc
Once you have the good utilities and understand how it works, it is easy to setup and need no more tweaks, unless you install new apps.
To keep a battery trace, current widget with logs and battery snap are mainly used.
1) Screen consumption
The screen battery consumption is huge when we use the phone. It was the same on windows mobile, and was to expect when buying it with that huge size.
Therefore, the screen brightness is an important factor to deal with.
In order to keep a good battery life when your phone is on, you need to keep your phone around 300 MiliAmpers or less. You have to keep in mind that a 75% brightness = 500Ma.
The best behavior is to keep your screen :
-25% brightness at home, with no sun.
-50% brightness mostly of the time
-75% and 100% brightness in very rare occasions with direct sun exposition.
In order to swich fast between this settings, and since we don’t have for now a functional kernel with auto brightness, using a brightness widget is recommended.
I personnaly use “Brighness level”, and launch it by swiping a dock icon into launcher pro.
Ps : Take care to not press 0%, or your screen will be completely dark. You can revert by guessing where the icons were, but it is tricky.
2) Memory management
In order to keep your hd2 fast and battery friendly, it is better to keep your phone with more than 200Mo free ram (when you are not using it).
There is a great free program for that, called task panel X. With it you can choose which program you want to close every time you put your phone in standby.
It is very important that you choose well the apps that need to stay in memory, and the others.
It is pretty simple: Keep the widget you use and system apps. Discard all the others by including them in the autokill list. It is a bit long to do if you have hundreds apps, but you have to do it only one time.
Example:
3) Programs launching automatically in background
You need to control the apps you install. Problem is that some programs are launched automatically into your memory at any time. I was surprised to see that programs that don’t need to be to stay in memory (when I don’t use them) launch by themselves at anytime. “Mabilo wallpapers” was the best (or worst) example.
You need an app to control that. I recommend “Startup Auditor”, and set carefully wich apps that can launch by themselves or not. Same as with task panel, just keep system apps and widgets. You can keep too your mail app. If you don’t use the Gmail app program, remove it from the list.
You will see into task panel that very few programs keeps running despite of that. You have to question yourself: “Ok this one is great to find new wallpapers, but it is constantly running in my memory and I don’t know why (suspicious) -> Do I really need it ?”
4) Programs updating in background
Programs that you authorize to launch automatically in your memory are often in order to update automatically things. (Mail, weather, facebook, tweeter etc…)
It is important that you know what they are, and where are located their update settings in order to not to waste uselessly your battery. Checking mails each hour or two hour is sufficient. Checking every 15mn cause obvious battery drains.
For most needs, manual updates for social apps or weather is sufficient, because it take only two seconds when you want to see them. If manual updating is not available, choose the longer updating interval (one day for example)
5) Builds
The following is based on my personal opinion; you are free to use and test every build you want.
First, i don’t recommend using sense builds due to personal bad experiments. I had crash and a lot of slowdowns, but most importantly it was battery draining due to all the htc third apps hard coded into. It is a build very hard to control.
I use and recommend a shubCRAFT 1.5 with stock Cyanogen mod 6 Final :
http://forum.xda-developers.com/showthread.php?t=740963
Don’t forget to download the 1Go user data file in order to install more apps.
It’s a build very fast to boot, smooth, efficient and highly customizable. The kernel provided in it is good for now.
Launcher Pro is used here, very smooth and easy to customize.
6) Wm rom, radio, Sd card, Cpu
SetCpu can be usefull, depending on the kernel you are using. There is a lot of threads on it, the most important setting is to downclock your cpu at standby.
Sd card
There is some evidences that your sd card can drain your battery. If you follow this guide and still have battery drain, it can be the cause. Check into this post :
http://forum.xda-developers.com/showthread.php?t=781433
I use a Kingston 16Go class 10 micro sdhc card with no issue.
Registry tricks :
I had before these regitry settings into windows mobile rom, no idea how it affect Android :
http://forum.xda-developers.com/showthread.php?t=585729
Radio
I use 2.12.50.02_02
Ppp or rmnet
I don't have dataplans, so i can't tell about rmnet or ppp battery drains, but my suggestions to users who use it, is to activate it when you turn on your phone or every one hour, with a third app like Tasker.
SuperUser permissions
Polo735 suggest that, in rare cases, the superuser permissions program can be faulty and need te reinstalled, otherwise it drains your battery.
Symptoms are : When installing an app requiring superuser permissions, no pop up granting it appear.
See his post here
7) Extras :
If you like the screenshots design, it is the stock Shubcraft froyo framework with a custom black toolbar form manup revolution theme, compressed for speed. You can download it bellow and copy the file to /sdcard/Android/root/system/framework/ You have to set some custom colors into the cyanogens mod settings:
-Toolbar color in black
-Clock color in white
-Date and toolbar title in white.
Have fun !
Nice one, thanks!

I use data and get 5mA in standby (screen off).
If this was true, the 1230mAh battery should last 1230/5=246 hours in standby mode running Android, which is 10.25 days, right?
We all know this isn't true.
The battery consumption gadget is cute, but not precise

Agree, it is a good build too. Cyanogen makes thing so smooth. I recommended Shubcraft, just because i have no drawback to say about it, but fortunately there are other builds we can use.

Who's gonna leave there phone in standby for ten days to test it, infact who's gonna leave their hd2 in there pocket for 30minutes, fact is my data is on I've just been to my current widget log and for the last ten minutes (logging every 2mins) my usage was 4mA, 5mA, 3mA, 6mA, 4mA
So you tell me? Guess the current widget doesn't work
Is there any other battery widgets so I can run multiple ones and compare.results?
I left off charge last night for 8 hours while I slept and used 5% I think its pretty accurate reality.

I made a simplier calculation. I lost 1% per hour, so 4 days in standby. maybe a more rigorous way. Current widget is not always very precise, but it can help a lot to trace possible battery drains.

Yeah, that's more accurate. That's approximatively what I lose too. But it's definitely draining more than 5mA.
It's not THAT bad, but Windows Mobile is still way more energy efficient.
My guess is that there are some things that should be turned off but aren't, hardware wise, when the HD2 runs under Android.

That's not the point of this thread. I am pretty sure this it is useful to new users because wm and android are obviously different to manage. I want to bring something rational here, talking about screen consumption and memory management. Not about "something" we can't see but drains.
I saw several windows mobile threads concerning battery life frustrations too, so it would be more constructive to make some real battery tests between this two Os. For now, what some users complains are just "feelings" for me.
Hey, I didn't want to belittle your thread, the OP is definitely useful
My point was, right now even with all tweaks, the situation is not really satisfying, and hopefully soon we won't need any tweaking anymore because the developers will have perfected the HD2 port.
One thing that may help some people:
Make sure that your phone is using superuser permissions correctly. A while back on an earlier build I installed setcpu and autokiller. I thought they were working correctly but my battery life was poor. I tried opening superuser permissions and it crashed. I uninstalled Superuser Permissions, then reinstalled. Now setcpu and autokiller work correctly and battery is very good.
There is no indication that these apps aren't working besides the "... granted superuser permissions" popup. If you don't know to look for that message you may not realize there is a problem.

Added in first post, thanks.
Hi all,
So, this problem appears common on other phones as well, and appears to be a Gingerbread issue. Drilling down further using Watchdog Lite on the phone, it appears to be a process called Suspend causing the high CPU usage.
There are a few threads on this:

Personally, I'm getting pretty terrible battery life out of my S2, and I can confirm that in the Battery Status menu, Android OS appears extremely high at around 40% (a friends Nexus has this sitting at around 2%).
Not sure there's much we can do about it but wait and hope for a fix from Samsung (or Google)... People are reporting that rebooting the phone can help, but it's only temporary.
Anyway, just something to check if you're having issues.
+1 second that.
Android os eats the most of the battery
Reboot helps temporarily.

OK. So now we have identified an "issue".
Could you guys post juiceplotter logs while phone is asleep and draining, and while in use?
For asleep, i mean literally not touching it for half an hour. On, just occasional tap to keep screen on.
What we are after is an idea of what is causing system to use the power. Can we compare configurations of push email etc, to see if anything differs?
Are we rooted? Etc

Hi mate,
I rooted my phone yesterday, but I don't think that's a cause as it was just as bad before. In fact I rooted it just so I could freeze some apps
At the moment, I only have my google account set to sync (calendar, mail, contacts), and I have gmail pushing through emails.
All the stock Samsung apps are frozen. No widgets are running (I'm trying to run it fairly barebones to see how long I can get out of it).
I don't have juiceplotter installed, I'll look into that. I do have Watchdog though, and from all the other threads on this issue the problem seems to be the Suspend process (confirmed by a Google employee).
I don't think there's much we can do aside from wait for a fix. The problem appears to have been around since at least September last year.
I had this the first few days I had the phone, my battery was being wiped out in hours.
I formatted both my mem cards and hard reset. Since then my battey life has been amazing (got through the whole day yesterday only using 25% battery), and os use has dropped to about 18% (still a bit high but better than 40%).
Same issue here, both new flashed roms and my own slim roms suffer from same issue. I have a look tonight if i can find any solution.

OK. I will see if I can think of anything, as I remember we fixed a similar issue when popping 2.1 onto it, when some binary was giving us trouble...
Root or no root don not affect this issue. Only time i dont get it: fresh flash of new rom without anything installed.
Same issue here and I rooted freezing load of Apps but still drain
*edit*
It seems to stop drain when using reboot the phone.. not yet confirmed just a speculation... Btw these processes eat a lot of battery never got these problems on sgs1 custom gingers rom

Haven't encountered the problem yet with pretty heavy use plus a few resets. It's probably a specific app or settings that you're turning on/using after each hard reset that causes it.
I'm still on the original firmware though, haven't flashed a new one yet. Might be related.
this is not universal, i don't have this problem. sgs 2 rooted with insecure kernel by chainfire.
*subscribing*
I also have the same drain issue. I have the S2 setup exactly the same way my Captivate was, and the battery life isn't the same.
I got better results after disabling background data in accounts ans sync (settings)
More testing ongoing.

Not really relevant I think - all Android users are going to have background data enabled in accounts and sync. Mine is enabled without the issue, anyway. I am only syncing a single gmail account though.
Have you tried what the linked thread recommends - going into manage applications and clearing data for the update system? You might want to try clearing data for all of the android system tasks.

As this topic already on debate, whether removing bloatware improves performance(by making RAM free) OR does it improves battery ?
Here look to screenshot
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So looking to this, i can say it doesn't affect at all.
As i have pure stock ROM with Stock kernel (Cf Root), and after 11 hr of use and 28% of total battery drain, there is not even recordable battery use noted. So seems if it remains there or does it remove there is no difference on battery
Regarding RAM, as we know there is LMK (Low memory killing) mechanism of android system, android itself keeping recently opened application in background to get quicker access to them, if we remove bloatware then it will be replaced by another applications which we have used recently till android system feels RAM is full.
So in short removing bloatware have cosmetic effect and keeps your device clean from appearing in drawer but not positive effect on RAM/battery.
wow.. another great stuff after mythbusting build.prop tweaks...
.. thanks for the post,
Doctor. Cant we have thread on various myth busters. Like for build.props, kernel cleaning script,etc. shared on xda.

I disagree on some points you made as facts.
I have been removing bloatwares including system apps, mainly from the manufacturer, for as long as I have learned how to root my phones. I learned how to do it in the hard way and from time to time I soft bricked my phone which I recover by re-flashing the Stock Rom again. By no means I'm encouraging anyone to opitimise their phones by start removing apps. However, in my experience I have had increased my RAM size by comparing how much free RAM was available before and after each optimisation right after a bootup. Also in my experience my phone is much smoother after I'm done with my optimisation process. Battery life also depends on what kind of apps are removed so it can have a little to noticeable improvement too.
Here are some technical explanations. Any apps that start up after boot completion event is triggered would decrease the RAM and they would most likely stay resident in the memory to do some kind of background process, example of such app is Google Play. Another example would be the screenshot service which must be running all the time for the time user gestures for a screenshot.
There are also apps that are launched when an event happens and not necessary the user intend to use them all. This would slow down the phone if few apps were registered for the same events, I have seen cases where apps wrongly registered with events that they don't depend on. Example; Media related commands such Volume UP/Down or headphone plug in/out. I have removed both Google's Music App and Samsung's so there are two apps less respond and RAM is consumed less when I launch my favourite Music app. Obviously the background launch of apps have some impact on the battery too and it would be obvious when the device constantly is being used, not occasionally.
I have already increased the availability of RAM right after bootup by over 50MB on my Note and close to 100MB on Motorola Atrix. Atrix runs on GB and without the optimisation it is very lagy to the point I cannot use it. On GNote the difference is way lower but still noticeable after the optimisation.
Basically, to say there is absolutely no changes in battery and performance is wrong because there are many other factors need to be considered. Thank you.

I agree with this. If I were to run a bloated stock Rom, I could produce several vastly different usage scenarios that would respectively
- not have negative impact on the battery
- have higher impact compared with the same usage on a debloated custom Rom, and
- have severe impact compared with etc.
In other words, if you tread very cautiously and are careful not burden your bloat too much it will be just as fine as any custom Rom. But if you are going to lean heavily on your bloat with WiFi, syncing, location on and at the same time playing online games, I'll bet you anything that it would drain battery much faster than a debloated custom Rom on the same scenario.
@CSharpHeaven
If you get my point, you can understand, removing bloatware freeup memory on booting surely, but as soon as you start playing with device, last used appl will be filled to background till RAM gets full. So effect is some what temporary. other thing if appli remain in backgroung it takes less time to re open(thats why android keep it in BG), and this way it increase performance.

Yes, but at least I'll have stuff I actually need running in the background, and not Yahoo Finance, Samsung Account and similar.
Though it may just be some placebo effect but removing bloatwares on your phone (samsung accounts, kies apps) does have some effect on the battery and on the overall performance of the phone.
Bloatwares that you don't necessarily need gives the RAM back to your phone and not only that.. it makes your AppDrawer clean for all the necessary apps that you really really need to be on your phone.
I prefer apps that I particularly need to use and not apps that just stays there but does not have any use at all (on my day to day needs).

But how long it remains there? it will just disappear when you start playing with device isn't?
Basically my aim is to explain - Removing bloatware doesn't make that difference if you are expecting so much, you might be aware of that many user just root their device to get rid of bloat for hoping their device will shootup like bullet and battery will last for days and days
thats not real.

I can't quantify the exact number of users running rooted stock compared to those who rooted to be able to flash custom Roms.
However, if the poll in 'What Rom are you using' thread is anything to go by, there's much more users on custom Roms than
on rooted Stock - check it.
Besides, compelling reasons for rooting your phone are not just bloat removal, but also
- ability to do backups/restores
- ability to flash other Roms
- ability to theme your Roms
- ability to customize Roms in many other ways
- ability to flash kernels that are faster and optimized to be more battery friendly, not to mention SAFER
And finally, to get back to the topic, to get rid of Samsung/carrier crapware and make your phone more responsive and battery efficient.
i became aware of removing apps ( the first target is what we define as bloatware) to free up space in system, so as I could install other apps which i wanted, sometimes for successful rooting purposes, newer mods etc
i never looked towards improvement in battery and performance, did not notice anything in normal usage...
the OP is very convincing
I have removed some 200+ MBs of apps from system including software update, Sam apps etc and there is hardly any increase in free ram, so I dont think removing so called bloatware increases ram.
But yes removing apps like soft update and sam apps which run consistantly in background helps to some extent in battery point of view.
I agree free ram will be occupied by other apps but lot of apps dont run in backgroung they just cache the ram and doesnt impact anything. For example once i saw s pen in cached process using 80 MB of ram but it was not actually running. I dont think such apps use battery or processor in background.
Its still a topic of debate and I think will remain same
Just my 2 cents

I'm not sure about not affecting memory... To be correct on this, need to look on all bloatware cached processes - sometimes there are too much. But, what concerns me more - is the process priority. I'm not sure, but those of /system, both apps & services, seems to get the higher priority, than /data apps. And in case of stock Sammy rom, it's obvious, that their crap will stay in memory forever.
@chasmodo
I think I cudn't explain you properly. I am not saying ppl rooting for removing bloatware only
I want to say my msg to those ' who are rooting only for removing bloatware'
Though these ppl are very few, but I just want to convinced only removing bloatware can't help you much.

In Android world applications register with events to be notified with both user and system actions such as GPS, Media Storage, Bluetooth, Wifi, App modifications (install & uninstall) , and so many other events. Also there are many apps that stay awake for some kind of background processing.
You are right to assume Android would kill any apps that is not being used and eventually reclaim the resources. What you have to bear in mind this cleaning process itself also consumes battery and CPU cycles. The smaller the list is, the shorter the CPU cycle would be. Furthermore, installing apps that hardly being used keep Android GC (Garbage Collection) busy because many of these apps coming alive (launching) when one of the events they registered with is fired.
After the first year with Android I learned to install only apps that I have daily use or use them very regularly. This is beyond me why people install over 100 apps on their phones.
By the way, launching apps in background for faster launch is fundamentally against app design for portable devices where resources such as battery is limited. In Android dalvik-cache takes care of lanching apps "quicker".
hello guys!
I've change a lot of rom and now i'm using the jb 4.1.2 of quarx (the stable one)
from some days i've noted that though in the settings the ram used is about 250 mb, any other program (clean master, smart cleaner and antivirus) says that my device is using over the 90% of ram.
in fact, my device sometimes is very laggy, until i clean the memory.. what i can do to fix this problem? i thought was a malware, but i cannot find any malware or viruses... help!
sorry for my english

Install 'greenify' from the market
And hibernate the apps u dont use,
Install memory booster from market
And keep cleaning the ram once in 10 mins,
And end the apps when u dont use them from the task manager
I m on 4.1.2 as well
I get 200 mb of RAM free on my defy normally
I have more than 100 apps installed

i'll try, but the problem is that also with another program (like ram booster) the sum of the used app from the list doesn't arrive to 470mb! it arrives at 240 maximum
it seems a "ghost" app is using my ram

Nothing like ghost apps exist in our defy
Cuz its ghost proof as well
Make sure u restart the fone after listening to music

I have the same problem of the wrong RAM usage readings on Easy task killer. I uninstalled it. But unlike you my phone runs fine.
Use greenify as rawwr said, and do not press home button to close an app. Clear recent apps too. In case your Defy has uptime of 5 days or more, then it is mostly be a memory leak.
now i've just done a full wipe, and then i installed mokee os crazy speed
the phone seems right, but the usage of ram is already high (the system says 170mb, all the other programs around 250 )
i really don't know what's happening. I know how to close the apps
any idea?

Probably one of your app is back biting you

two things here:
How much ram you have free is of consequence if your phone is laggy. facebook *example* by default is a laggy app. if its your first time logging into an app even in 24 hours its going to do that. most would assume it to be attributed to ram. not always the case.
second. decide what apps you keep switching in and out of; take a day or two to do it. then keep those apps in memory. for example i use contacts, whatsapp, sms, instagram and twitter a lot. so i keep them in ram. foursquare not so much so i greenify it. this process helps you do thinks you need to do.
but if you still think its ram try another OS or an overclock

as you see, there is a difference instead clean master and application list of android, but in every list we can't read why the phone has only around 160 mb of free ram. if we sum the ram usage of every single process, we can't have that result...
any idea?
The difference here is that the system is not showing you the cached processes. Add that in and you will get the sum total of used ram. Cached processes are relatively fluid duo they come and go.

ok then
Good day!
A few days ago I receive my SmartWatch PS-SW308 from cwell-hk.com shop.
Device is very useful. Work fine with Android 4.0.4. But battery is very poor.
If at 6 am I disconnect them from charger with 100% charged, now is 10:14 am and it is already 82% charged.
CPU is MTK6517.
Please help! What I can do for extend working time?
In battery log is:
Cell standby = 51%
Phone idle = 48%
and nothing else.
Happy to answer any questions on the device
Is your email set up?
Are you running ANY social media apps?
Have you installed any additional apps?
If yes then what apps have you installed?
Are you using it as a phone or a companion device?
If you are using it as a phone, what is your signal level like?
Is WiFi on?
Is Bluetooth on and are you using it?
The MTK6517 is a Cortex A9 which tends to be a little more power hungry but hopefully we can help you get some better battery life out of it.
I'll alos have some other questions and a request or two but will wait til after you answer the others.

Thank you for your reply.
- yes, I connect one email - google account with push.
- no. Social software not installed.
- installed only Browser, E-Mail Client, Play Store and Gmail. Other apps is not sunchronise data from Internet (file manager, clock, SIM Manager, etc)
- yes, I use it as a phone, but no calls, no messages... Mobile data is off. Only network idle phone process - I want to know how long its will be work in idle mode ...
- Signal may be variable - in Moscow metro is poor, on the street - good level.
- Wi-Fi - off, BT - off, in the future I planning to use BT headset with that.

Disable push and set the sync time to something more reasonable. I normally set my devices to one hour and have folks text me if I need to check it right away.
Low signal will eat a battery on some devices. That may be part of the issue here.
Set screen timeout to 15sec
If rooted then try a CPU app (may take testing a couple apps before you find the right one) and try to get as close as you can to the following;
Min-216, Max-750, Governor-Powersave, Sheduler-Deadline
Profiles:
Screen Off: 216-312, Governor-Powersave, Sheduler-Deadline, Exclusive
Call State (In Call): 216-456, Governor-Powersave, Sheduler-Deadline, Exclusive
Charging State (Charging): 216-max, Governor-Powersave, Sheduler-Deadline
Also set Play Store to only update over WiFi.

Thank you for tips. I already set parameters as you write above, but receive very small profit.
Yesterday evening I turn off radio module and battery is 18% off charge (about 11 pm). Today morning (6:15am) it is 1% and shutdown when I turn on screen for check battery log.
I think its not rooted. How I can check that?
'su' command in terminal emulator write that application not installed.
What CPU app do you recommends for me?
p.s.: sorry for my very bad english...
Sounds like you are not rooted. Wish I wasn't still two weeks away from getting my hands on a similar device. Hit up the GiGs Samrtwatch thread as the devices are the same. They are talking root and may have some on hands help that I can't provide yet. Once you get root we can go from there. CleadD is also a good dev to ask for help as well.

This is a great news!
Today evening I try to get root. But afraid get a brick
With CPU Identifier recognize that CPU is MTK6577, its very strange, because seller write that them is MTK6517.
What do you think? May be that?

Please help me to do firmware file.
I try to use MTK Droid Root & Tools v.2.4.8 but its don't work - restarting and no root access enabled.
I try to get root with Root_with_Restore_by_Bin4ry_v29 but no results
I try MTK6589_6577_w6575_V1.06 - but root not enabled.
SP_Flash_Tool_v3.1224.01 is "Searching" and not find anything.
Once what I can do is get scatter file from device with map of memory blocks.
Good day.
I get root via Framaroot 1.6.1 with Boromir exploit and install SuperSU.
All works fine
