Basic & Useful information for Galaxy J5 suite​
In this thread you'll find useful informations along with a list of available Custom Roms and Kernels for our Samsung Galaxy J5.
Let me know if you think there is some information I should add in this thread, to improve it.
Post #1: What is a stock & custom rom, KNOX, root, custom recovery, download mode, xposed framework, kernel, customkernel, governor's, +
Post #2: List with custom roms and kernels available, how to flash/reflash stock rom, install custom recovery, how to root, how to flash a custom rom, how to UPGRADE & DOWNGRADE 5.1.1<=>6.0.1
Post #3: Credits
1) What is a Stock ROM?
Click to expand...
Click to collapse
It's the original operating system provided by the manufacturer of the device.
2) What is a Custom ROM?
Click to expand...
Click to collapse
It's the operating system ported, developed from source or derivated from Stock Rom, created by developers.
3) What is KNOX?
Click to expand...
Click to collapse
"Knox is a new security feature that is being offered with certain Samsung handsets. It helps you to securely separate your personal and professional data. Essentially, you can have the benefits of using a ‘work phone’ without the need to carry, and secure, a separate device." -blog.clove.co.uk
"Normal(unrooted and so..) devices are flaged as KNOX Void Warranty 0x0 right from the factory.
When we flash items which weren’t signed by Samsung, it flags your device as KNOX Void Warranty 0x1.
So, flashing root/kernel/recovery/latest firmware by samsung/etc. will set KNOX status to 0x1." - omegadroid.co
Once the KNOX gets voided, you lose the warranty. (there are some cases where people say that Samsung repaired their phone for free while Knox was voided though)
4) What does mean ROOT?
Click to expand...
Click to collapse
"Rooting, for those of you that don’t know, means giving yourself root permissions on your phone. It’s similar running programs as administrators in Windows, or running a command with sudo in Linux. With a rooted phone, you can run apps that require access to certain system settings, as well as flash custom ROMs to your phone, which add all sorts of extra features. If you’re on the fence about rooting, check out our top 10 reasons to root your Android phone for some motivation." - Lifehacker
5) What is a custom recovery?
Click to expand...
Click to collapse
"A custom recovery is a third-party recovery environment. Flashing this recovery environment onto your device replaces the default, stock recovery environment with a third-party, customized recovery environment. This is a bit like flashing a custom ROM like CyanogenMod — but, instead of replacing your device’s Android operating system, it replaces the recovery environment.
"A custom recovery environment will do the same things as the stock Android recovery. However, it will also have additional features. Custom recoveries often have the ability to create and restore device backups." - howtogeek.com
On our Galaxy J5, you can enter the recovery by holding Power + Home + Volume UP buttons.
6) What is download mode?
Click to expand...
Click to collapse
"Download mode is for flashing radio firmware/ROM upgrade through official means.
For example, ODIN is commonly used on Samsung devices to flash ROMs, those devices needs to be in download mode prior to flashing. However, ODIN is not the official way to do it, rather Kies, is the official route in upgrading the firmware, this is for Samsung devices for example." - android.stackexchange.com
You can enter the download mode by holding Power + Home + Volume down buttons.
7) What is the Xposed framework?
Click to expand...
Click to collapse
"The Xposed Framework is a way to make system-level changes to your Android operating system without installing a custom ROM. All you need is root access." - howtogeek.com
For example, you can remap your phone buttons, gain control over apps permissions and some more privacy, customize your phone.
Take a look here.
8) What is SELinux?
Click to expand...
Click to collapse
SELinux, which was introduced in Android 4.3, is a mandatory access control system built into the Linux kernel, in order to help enforce the existing access control rights (i.e.permissions), and to attempt to prevent privilege escalation attacks (i.e. an app trying to gain root access on your device).
9) What is Governor?
Click to expand...
Click to collapse
A CPU governor in Android controls how the CPU raises and lowers its frequency in response to the demands the user is placing on their device. Governors are especially important in smartphones and tablets because they have a large impact on the apparent fluidity of the interface and the battery life of the device over a charge.
**source and each governor explained:http://forum.xda-developers.com/showthread.php?t=3048957 Thanks to @gsstudios for detailed explanation and hard work
thanks to @Sehab084 for directed me
10) What is Kernel and custom Kernel?
Click to expand...
Click to collapse
KERNEL It's the core of the operating system that handles requests to and from the hardware, memory and process management and all the low-level stuff that is necessary for Android to be able to run.
CustomKERNEL Custom Kernels are nothing but modified stock kernel. Its done in order to achieve some features which is not present in the kernel provided by Manufactures. You can find one for your device if anybody has created a custom kernel for your "device". Kernels are device specific too.

@vaserbanix
I've sent you a PM with a new code for the posts, looking much more cleaner and easier to read in my opinion.
I've also added some more information, corrected the typos and replaced some words with ones better. My English isn't perfect neither, but I think is better than your
I hope you replace your code with my code. I've spent like 4-6 hours to do it LOL. I've done it on my phone.
Also, I think we should add this thread in our signature.
Have a nice day!

Nandroid backup
Basically, this so-called Nandroid backup can save you a lot of trouble in case you soft-brick your device. In just a few clicks, your whole system is restored and your device is fully functioning again, as if nothing ever happened. In this short guide, I’ll give you the simple steps so that you can make a backup yourself to be on the safe side. I’ll also show you how you can transfer your backup to your computer so that you don’t need to keep it on your device to save space.
How to do a Nandroid backup
1. Prerequisites
In order to be able to make a Nandroid backup, your Android device has to be rooted and needs to have a custom recovery tool.
2. Go into recovery
To get into your recovery, you first need to boot your device into the bootloader. This can be done by turning it on holding down the Power + Home + Volume UP buttons.
3. Do the nandroid backup
Once you’re inside the recovery it’s a piece of cake.
TWRP:
Go to “Backup”
Choose the partitions you want to back up. If you’re not sure what to choose, simply leave the default selections.
Make the backup by swiping to the right at the bottom.
Your device should now perform the backup process, once that’s done you can reboot your device.
4. Transfer the Nandroid Backup to a computer
Now, depending on how many apps and files you installed, your backup might take away quite some space. To avoid that, you can transfer the whole Nandroid backup to your computer and delete it on your device. Should you ever need to restore your device, you only need to transfer it back.
TWRP:
Connect your device to your computer and go to the TWRP folder on your device. In there, a folder containing your backup can be found. If you have several on your device, they will be separated so that you can choose only the folder you need. After you successfully copied the folder, you can delete the one on your device.
5. Restore your device using your Nandroid backup
That’s an easy one as well. Simply boot into recovery, select “Restore”.
Now you can choose the backup you want to use and restore your device. Once that’s finished, reboot your device and you’re done!

big thumps up
As a newbie, I couldn't figure out why the custom recovery was not could not be flashed properly. Until I found this thread which told me the steps that I was missing:
03. Goto "settings>>about device" on ur j5 and tap built number 6,7 times to enable developer options.
04. Enable "OEM unlocking" and "USB Debugging" .
Click to expand...
Click to collapse
Is it an idea to add those steps to the 'how to'? Or are these steps so obvious that only a newbie does not think about these steps?
For the rest, big thumps up for this Q&A and the 'how to's' !! :good::laugh: They are very useful for someone who is just starting to play around with this stuff. Now I'll try to go for a custom ROM and see if that might improve the performance.

You did a full wipe from

Or a wipe dalvik cache before reboot the phone after the flashing was finished?
