[Galaxy Note II Q&A, Help & Troubleshooting] keebb9:
Hi Guys,

I'm from the UK. I've previously owned a IPhone and I decided to try out Android and I love it. So I then purchased a Samsung Galaxy Note 2 from a local phone shop. I bought the phone brand new and I was the first one to open the seals.

I had the phone for 2 days and today I was getting a message saying mobile network unavailable, emergency calls only, so I restarted the phone and that didn't fix the issue. I then decided to try my friends sim card and that didn't work, so I came to the conclusion that the phone is blocked or blacklisted or reported stolen.

So I went for a trip to the phone shop where I bought it from. The manager tried another sim card and still it wouldn't make a phone call. The manager said he would flash the phone and do a factory reset. So I was waiting for about 45 mins and he came back and the phone had SuperSu installed.

What is SuperSu all about?

is it a illegal software?

Thanks
[Galaxy Note II Q&A, Help & Troubleshooting] Heppieboeddah:
SuperSu is there when the phone is rooted. I suppose the guy has the phone rooted.
[Galaxy Note II Q&A, Help & Troubleshooting] CitizenLee:
A Heppieboeddah says, the phone has been rooted and while there is nothing illegal or wrong with that (most of us on XDA do it as soon as we get a new phone so we can remove bloatware, install custom ROMs etc), it's not something I would expect a legit phone shop to do as arepair.

I would ask for a refund as it sounds like the IMEI has been blocked, usually meaning it has been reported lost or stolen like you say. Even if it hasn't the phone isn't fit for purpose so you're well within your rights to request a full refund.

Then go buy a new phone from Carphone Warehouse or Phones4U etc, somewhere reputable.

EDIT: I wrote my initial reply on the assumption that you haven't modified the phone in any way and it is 100% stock, but I should have asked first, have you done anything to the phone... like installing custom ROMs? Is so then SU is just part of the rooting process and it may be that you have done something to cause the problem yourself. It would also mean that if you do need to return the phone then you will need to follow certain steps to return it to an unmodified state. Talk us through what, if anything, you have done since buying the phone.
[Galaxy Note II Q&A, Help & Troubleshooting] keebb9:
Hi, the phone is stock, I didn't install any custom roms or software. As I was new to Android, I wasn't too sure about rooting.

But I don't understand why he put SuperSu on the phone.
[Galaxy Note II Q&A, Help & Troubleshooting] hunter68uk:
SuperSU is part of the rooting process like CitizenLee said take phone back demand a refund and go to somewhere reputable and buy a Note 2
[Galaxy Note II Q&A, Help & Troubleshooting] davjmazz:
curious. after this "repair" the bloke did, could you then make phone calls?

i dont suppose you looked in the settings, about phone, status and noticed if you still had an imei number did you? before and after the "repair"

regardless, i agree with the previous posts and would definitely take it back, get a refund and get one from a known phone shop.
[HTC Rezound] bik2101:
Anyone know if there's any way to test batteries to figure out if they've degraded or not?
[HTC Rezound] Flyhalf205:
Yes. I have tested mine about 2 months ago. I have 3 batteries. None passed 75% capacity.
[HTC Rezound] bik2101:
Care to share how you tested them?
[HTC Rezound] Flyhalf205:
I work at a BatteriesPlus and we have a machine to test capacity of batteries. :D

Also the more expensive multimeters have the same ability..their pricy tho..
[HTC EVO 3D] beneath-a-burning-turtle:
Need a good recommendation for a wakelock killing app, my phone is awake 90% of the day even though I've had maybe 45 minutes of onscreen time at school, and another 10 so far at home. Screenies attached, I'm running my rom (ironically) 100% stock, no custom kernels or anything. This is gonna bother me to no end if I can't find a solution lol
[HTC EVO 3D] coal686:
It's better to find the cause than to treat the symptoms. BetterBatteryStats XDA is free here. It can help you figure out what's going on.
[HTC EVO 3D] beneath-a-burning-turtle:
Thanks, I just needed something that'll tell me what's going on so I can do something from there. Thanks man

Krazeecracker, Thomas.Raines and Team Fah-Q! presents

The Lightning Zap! kernel for the Hercules

ATTN:

I Krazeecracker, thomas.raines, Team Fah-Q!, nor it's affiliates claim responsibility for anything you do to damage, destroy, brick, explode, or otherwise screw up your device.

I revamped the Lightning Zap! kernel across the board. Since I have so many of them I was loosing where I was on each one. So I have now broken it down into 3 phases:

Phase 1: Introduction of LZ kernel to device

Phase 2: Fine tuning of tweaks, values, etc

Phase 3: Implementation of OC/UV

Phase 4: Continue updating and adjusting as necessary

From now on I will name the .zip accordingly as well:

Sky_p2.1

On a good note, I think this latest update will finalize phase 2 and now I can work on OC/UV...

Features:

Improved performance

Improved battery life

Improved network speeds

Improved boot times

Smoother scrolling

Better responsiveness

Cleaner file systems

Governor tweaks for amazing speed and performance without sacrificing battery life

Improved Memory and Ram tweaks

Improved Internet speed

Amazing kernel tweaks, build.prop mods, init.d scripts and more!

Instructions:

Make a backup

Download LightningZapv1Sky.zip to PC

Transfer LightningZapv1Sky.zip to your sdcard

Or just download it straight to your phone

Reboot to recovery

Flash

Phone will automatically reboot after install**

Wait 10 minutes

Enjoy the Lightning Zap!

ATTN!

If you are currently on any version of Lightning Zap! kernel, you must either replace your build.prop from your ROM or re-flash your current ROM. Or you can open your build.prop with a text editor and delete all lines below the Lightning Zap Tweaks entry.

This kernel was tested on ParanoidAndroid. This kernel and tweaks will work with any version of CM10 post 14OCT.

**First boot, especially after a fresh install of your ROM (wipe system cache etc, flash ROM gapps Lightning Zap) will take a while. It will seem to hang between a blank screen (which use to be the 2nd boot splash) and the boot animation. There is no need to panic. Everything is fine. It is the vacuum script trying to clean databases that have yet to be created. After first boot, your phone will boot as normal (a little faster actually)...

After first boot, ensure your I/O scheduler is set to cfq and your governor is set to ondemand to gain the maximum benefits of Lightning Zap!

See 3rd post for further instructions on improving and customizing your Lighting Zap! experience.

Download links and changelog

Downloads and changelog

Sky_p3.2-1.zip

Vibration fixed thanks to tmob.

Sky_p3.2.zip with rotation fix included

Skipped 3.1 because it was incomplete

Added userspace voltage control (You can now use an app or script to control your voltage. I tested with Voltage Control (preferred) and Antutu CPU Master)

For badass battery life, I am using noop io-scheduler, Lionheart governor, underclocked at 1026Mhz, and globally dropped voltage by -100mV

Deep sleep is working right again (doesn't take forever for it to enter ds)

Leaned up thread and removed old versions. They are gone for good so please don't ask...

Sky_p3.0.zip

Fixed the ability to set max/min cpu frequency. Thanks to car vs driver for pointing me in the right direction

Added OC/UV from flappjaxxx h0tcakez kernel source

Fine tuned ondemand governor

Archived changelog

Plans:

I want to trim down the oc frequencies. I think that 29 is just too much. I also want to cut back on the governors and io-schedulers. There are so many to choose from and everyone has their preferences. How bout some feedback in the general scetion here

Enjoy the Zap!

More tips and tricks

This is already included but left for reference.

The governor tweak is set for a fairly balance of performance and battery life. If you find yourself needing battery life over performance, you can make some minor changes. Here's how:

1 Download Script Manager from the market (it's free)

2 Open Script Manager and navigate to /system/etc/init.d

3 Press menu/more/advanced options and select mount as RW

4 Select 01governor and select "edit" at the top (this will open the file in atext editor)

5 Uncomment (remove # in the particular line) and change:

echo "45" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold;

To:

echo "[COLOR=red]70[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold;

6 Select menu/save

7 Press the skull and cross bones icon at the top (this will allow Super User)

8 Press run, close app and enjoy

This will result is slightly slower performance but higher battery life.

If you want even better battery life:

1 Following steps 1-4

2 Add a # at the begining of lines 11 to 19

3 Scroll to "pwoersaver" section

4 Remove the # at the begining of lines 28, 30-38 and 43

#AWAKE_GOVERNOR="ondemand"
#SLEEP_GOVERNOR="ondemand"
# echo "70" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold;
etc

AWAKE_GOVERNOR="powersaver"
#SLEEP_GOVERNOR="powersaver"
echo "20000" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate;

5 Follow steps 6-8 (no need to select super user icon if you already did)

This will result in lower performance, but ultimate battery life

When running in a higher performance mode (especially for gaming) you can disable powersave_bias by changing the 1 to a 0 like this:

echo "1" > /sys/devices/system/cpu/cpufreq/ondemand/powersave_bias;
echo "[COLOR=red]0[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/powersave_bias;

Powersave_bias only allows the CPU to peak for small increments at a time, and not allow the CPU to remain peaked even when the system calls for it. In gaming, that could result in choppy, laggy perofrmance and slow FPS..

Although it says not to in the script, you can change the sampling rate as well. Do not go below 50000. I left it at 57500 as I found this seems good setting for smooth scrolling and performance.

echo "[COLOR=Red]57500[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate;

Always leave SLEEP_GOVERNOR="powersave" uncommented (no #) and do not uncomment any other SLEEP_GOVERNOR as this will keep ultimate battery save while screen is off.

Only change values in increments of 5 for the up_threshold.

This is already included but left here for reference.

Source code tips

Needs updating.

just add this to your local_manifest.xml:

<remote fetch="https://github.com/TeamFahQ" name="LZkernel" />
<project name="msm8660-common_lz_kernel.git" path="samsung/msm8660-common" remote="LZkernel" revision="jellybean" />
<project name="vendor_lz-kernel.git" path="vendor/lz-kernel" remote="LZkernel" revision="master" />

Then add this to your cm.mk file i your device directory:

# adding Lightning Zap tweaks to build
$(call inherit-product, vendor/lz-kernel/lightningzap.mk)

And don't forget to remove the kernel entry in your cm.dependencies found in your device directory...

[T-Mobile Samsung Galaxy S II SGH-T989] krazeecracker:
Lol, basically just flash with the rotation fix and your good to go. If you have the need for more juice then follow the third post. And fourth is for adding to an existing ROM your going to build, i.e. your kangs :D

I am currently on all-star ROM and on speed test the download is about 1mb slower but the upload was about 1.5mb higher on my network. I also notice the vibration isn't as strong is that me or does it have to do with the kernel as for battery I'm not sure yet. Thanks

[T-Mobile Samsung Galaxy S II SGH-T989] HiM@L:
I haven't installed cpu sleeper yet...

i believe it doesnt play nice with JB i think... like when i was using GBean rom i had cpu sleeper installed and it lagged when ever i unlocked my phone and started using it. when i uninstalled... lag was gone. so i never install cpu sleepef although i have paid version.

[T-Mobile Samsung Galaxy S II SGH-T989] krazeecracker:
a lot better imho, i can get 5.5 - 6 hours on screen time versus maybe 3.5 with kko. Plus this is using newer sources.

Awesome I will flash now
[T-Mobile Samsung Galaxy S II SGH-T989] gruntparty:
Word of advice/request.

If this is the case, can you just port specific features like OC/UV to CPU & GPU to this kernel along with other background tweaks which helps make our devices much more smoother along with I/O performance boosters if possible without affecting the battery significantly. I really want this kernel to be the best one in the house with excellent battery life for our devices while including that extensive governors/scheduler list.

What i want to emphasize though is time. Take your time to do stability checks and just implement new features in baby steps.

OC/UV is now part of the Lightning Zap! kernel!

Even though this is the final phase in building the LZ kernel, there is still some things I intend to do such as:

Fine tuning governors and other values

Implement scorched io-scheduler and governor

Remove unneeded/unwanted governors

Fine tune other values until the Lightning Zap! kernel is the best with performance and battery life.
