Ultimate Android Rooting, Customization & Knowledge Database

Android offers tons of ways to modify and customize your mobile device. You can add features, change the look & feel or improve the battery life. Many people are simply overwhelmed when they first look into the sheer endless possibilities.

Where do you start? What’s important to know? We’re here to help you!

In the last months, we published many Android-related guides to help you understand Android a bit better. This article will give you an overview of the topics we’ve covered so far. Please let us know if you’re interested in a certain topic and we’ll do our best to help you!

Backups & Preparation

Before you go ahead and modify your Android phone or tablet you should always perform a decent backup. Many people are scared that they, somehow, break their device if they start modifying it – that’s okay. Especially, if you’re not that tech-savvy. I fully understand your concerns. Having a proper backup is crucial and can help you to bring your (almost) broken device back to life!

There are basically two important backups: A NANDROID backup is a full backup of your device data. If your phone does not start anymore, a NANDROID backup can get it running again.

Titanium Backup, on the other hand, lets you backup all your apps which comes in quite handy when flashing a new ROM. Not only don’t you have to download all your apps again, but it will also save your settings and game progress.

Rooting Process

Rooting your Android phone or tablet is the first step required to modify Android on a deeper basis. It’s required for custom ROMs, kernels and certain apps. If you’re not sure whether to root your Android device or not, have a look at our overview of rooting reasons & benefits.

how can i unlock usim personalization and solve ussd running error in SHV E250K


dial 319712358

password : 774632

this will open a hidden kt menu,, but still can hlep to solve the “ussd code running” error.. i cannot run

any ussd codes in my note2. i can use any sim to call msg 3g etc… but cannot use ussd codes like *12345#

etc.. so i cannot use the code

to Go to ServiceMode by dialling *#197328640#.

but after entering shows ussd code running..

how can i correct this, My cellphone tracker is switched off too.. Note2 is running on 4.3 android, olleh

version of note2..SHV E250k , firmware is E250KKKUENC3.

As well another problem is i tried to change usim pin, but after entering two times defauld 1234 , the

phone cannot unlock and has one more try left, i hard reset the phone but it shows still the same..

usim personalization to {dont require password to use other usim} also is locked with a password.

How can i open those…. Will a rooting solve these problems, I also want to remove the olleh screen that

appears when phone starts.

ThankYou, good day

thankYou again


i have this phone aswell. how did you unlock for use with any sim?


I might have changed the gmail password. Now the android download is not taking the new password or letting me change the PW. error is 3007 and 2000.
what can I do now?


You mention that you have to do a full back up of your phone before the Root process but fail to mention how to do just that. A nandroid back up is only for Rooted phones so what’s the alternative?



Noob question – I am on 4.4 version . Can i flash a lollipop custom ROM
on top of it? or vice versa too flashing kitkat rom on stock lollipop

Thanks in advanec


depends on your device if it has a custom rom made for it

Chris Hoggsays:

Hi mate, I have a smsung note 10.1 running kitkat 4.4.2. rooted. it appears that this system is unable to mount a usb pen drive via OTG. is this a hardware issue or can it be fixed with a custom rom? I did find one site that suggested entering this command “setprop persist.sys.usb.config mass_storage,adb

echo /dev/block/vold/179:33 > /sys/devices/platform/msm_hsusb/gadget/lun0/file”. what do you suggest. Also I am having trouble with connecting usb dongle to access internet. will either of these fixes help that isue also. P.S. I am a newbie. less than 12 months pc experience, but very keen to learn. Cheers Chris.

Ashish Aptesays:

Every time I try to boot into custom recovery with various combinations (rom manager, G pro recovery, freegee, using volume and power key etc.), I an not able to do it. I get a message as under: Secure booting error, cause: boot certification verify..with LG logo. When I boot the phone normally I can perfectly use phone. I use LG Optimus G Pro E 988 India version… Any help please….


Correct me if I’m wrong here… I’m here to learn how to basics of rooting my phone.
This page tells me that before rooting I should either NANDROID backup or Titanium Backup. I click the link for NANDROID backup as it sounds better. The link says I can only do it on a rooted device, but here it says I should backup before rooting… Bit of a true chicken or the egg dilemma here… Great start for a guide! /eyeroll

Claude Akisays:

Hi Philipp,
Can you answer the question that XionEternum asked ?
It look a bit weird to have to be root to make a backup before to root your device, right?
