ROM Porting

I have Samsung Galaxy Tab II 7.0 (GT-P3100)
It came with ICS 4.0.3 upgradable to 4.1.1
While playing around with it, I rooted it, installed a Custom Recovery (CWM) and a Custom ROM (CyanogenMod 10.1), Android version 4.2.1.
Now everything is just fine except a few bugs that are normal in Nightly Builds.
I want to re-install my Stock ROM because I want to sell it and the buyer wants official stock ROM.
One of my friends has the same handset (GT-P3100) with same baseband version (P3100DDLG1)
The only thing that he did was that he updated his one to official JB update OTA (4.1.1)
He also rooted his phone.
Now, I want you people to help me, how can I copy his Tab's ROM and install that on mine.
I want instructions to be easy and porting procedure simple.
Like the way I install updates for CM 10.1
Thanks.

Wrong forum, my friend: you have the Galaxy Tab II (GT-P3100), while this is for the Galaxy Tab 7.7 (GT-P6800/6810/I815).
But the answer would be the same.. You don't want to port a ROM (that would be trying to make a Galaxy Note 10.1 ROM run on the Galaxy Tab II 10.1, for example: make a ROM run on a device where it wasn't meant to run): you want to "transfer" a ROM between two different devices. And that is quite easy. Your friend makes a CWM backup. You get that backup on your tablet, and restore that backup. Then you'll have the exact same kernel, system and data as he does. Then, you factory reset to erase the data, and you'll have the ROM as if you'd just installed it fresh. You'll probably still be rooted, though.
A more straightforward way would be to simply download the ROM you want from SamMobile and install it through Odin.

Thanks for the Answer Brother...
Actually I'm new to XDA forums,that is why I'm a little confused between "forums", "porting", "posts", "topics", "transfer"...
Anyways I know how to make the Backup of ROM in CWM although I don't have any idea where are the files stored on the tablet.
I mean when my friend creates a backup via CWM, where will be the "Backup ROM" stored (path)
if you can help...
Thanks in advance.

For better batterylife, temperatures and peformance, better sound and display. A good custom kernel will improve the phone a lot bro imo.

This is also my first nexus device... I have always had HTC before and rooted every phone that I had... This is the first phone that im happy with stock rom, but I would like to change the kernel... My question is how quickly will the stock rom be posted up with every update... I know I'm not going to really want to wait...

I've had Android phones for a few years but never rooted until I got my Nexus 7. I've loaded roms but havent delved into it too hardcore. This is also my first Nexus handset device.
As far as rooting - the replies here have outlined the benefits. If you simply root and unlock bootloader, then you can still receive the OTA updates. however, if you load up a rom, you have to wait until the developer incorporates the updates - unless, the rom already has anticipated and tweaked those issues in a positive way.

If you need to ask why you should root then you probably shouldn't; it's not a question of Chrome vs Dolphin or Nova vs Stock Launcher..
Here's a nice little article: http://google.about.com/od/socialtoolsfromgoogle/a/root-android-decision.htm.
Read around as much as you can and don't use a toolkit. Go the route that is described in the link in my signature. Make it a learning experience!

google usually posts the full stock images within a couple weeks of OTA.

I rooted my first device (Galaxy S2) when I became tired of Touchwiz.
I rooted my Motorola RAZR HD because there was no possibility to silent the camera shutter sound without root (I renamed the system sound files).
Now I rooted my Nexus 5 because I'm using Greenify and AdAway which only works with root access. I'll also try different Recoveries, Kernels etc. to increase the performance/battery life in the future.

Titanium Backup. 'Nuff said.

This is the first phone I haven't rooted within minutes of owning, partly because I've been busy and party because I'm really quite happy with it. Unfortunately I need root for ad blocking so I think I'll be doing it today.

Adblocking through hosts files. Also you can use droidwall to select which apps get cellular data and which apps get wifi only and which apps get no internet access. Secure settings app will allow you to set conditions to set and remove your lock pin based upon conditions set by an app like tasker. I use this to enable lockscreen when not in range of my bluetooth headset or home wifi.

no reason at all!!! but it's fun to flash things.... and kernel upgrades if they are done well can make you feel a bit more elite with some nice things. depends on the device and there is a lot of gimmickry with roms and kernels out there. but this being a nexus there might not be as many issues with modifications since there aren't so many manufacturer proprietary binaries and unusual dependencies. but sometimes on the kernel end they can upgrade sound and video drivers, or adjust parameters that effect battery life and things. my old captivate would go as much as 4 days to a charge becasue the gingerbread and even froyo development comunity on the i9000 was so good. the infuse i replaced that with never got that level of kernel support.
if you don't have an expressed need to root, like maybe for unlocking a feature the carriers took out such as teathering, or removing factory spyware like carrier iq (not that they do that anymore to my knowledge) or certain applications then rooting isn't really needed.

[Q] from stock to custom

Hi all,
I am using n8000 from a year now and for me it is the first android device that last with me a complete year with a stock rom ...
I can see the stock rom very satisfying but i only had 2 problems :
1- it is not customizable ( as I need)
2- 4.1.2 jb !!! I cant move my apps to sd ( I had low memory issue now)
So I decided to try a custom rom and all what I need is to find a rom that satisfy my daily usage:
1-I am using my tablet as a phone so I need a rom with a working headset Mic
2-not using S note app alot (occasionally)
As long as as I search here In xda I can't find what I seek so if anyone could suggest a rom for me, I would be grateful.
Thanks in advance

If your happy with your current ROM why don't you just root it and install folder mount [root] from the play store and transfer your files to your ext storage.

as it is rairly updated
As it is rairly updated (4.1.2), not customizable (year of usage and it is the same UI and the same everything) and if am going to root it anyway so why dont try a custom rom ?

I am happily rooted using folder mount. I also use nova launcher on my son's n8013.

I too am happy with 4.1.2 (I would be happier with a certified 4.3 or 4.4).
You say "just root it." For us dummies, how do I "just root it?"
If I do that and then Samsung updates the firmware, will I get it ok or must I "unroot."
How does one "unroot?"
Many, many, many thanks for any understandable instructions.

It looks like you are new here so it may be best for you to start out rooting your Note 10.1 and then maybe install a different launcher.
For your own good read, understand and follow any and all directions EXACTLY when rooting and or installing a custom firmware.

[Q] How to Root Samsung Galaxy S 4G and Install Jelly Bean 4.3 (CyanoGenMod)

Hi Guys,
I am an IT person, but totally new to Android. I am having Samsung Galaxy S 4G (T959v) running GingerBread (2.3.6).
I had upgraded from Froyo to GingerBread using Kies mini... and since that I am facing a lot of issues running... like slow responsiveness, phone hangs, some times unable to make calls, very high RAM usage etc...
So to fix these issues, I am thinking to install custom ROM (Jelly Bean 4.3 - CyanogenMod 10.2). But I don't know how to do that.
What I read on thread is it first needs to ROOT the device, but I am not sure how to ROOT the device.
Please help me to ROOT the device in easy steps and install custom ROM.. (Off course without bricking my device )
Thanks.

Look at the second link in my signature. Instead of flashing the whole package just flash AntonX's kernel. Read the first couple of posts in the Heimdal thread and you will hopefully know what I am referring to.
From there, follow the directions in the OP of the ROM thread that you would like to flash. The OP will also tell you what works and does not work for that ROM.

I would suggest making a backup copy of your efs folder for the just in case..

You can find the Wiki, FAQ, lumin30's guide, and more here.
Like I said before, you have to search and read.

Thanks guys for all info and help.

I liked the new experience (I am coming from stock GB) ... Trying out the stuff now...
thanks again!!!

Galaxy tab 2 10.1 P5110 - Latest stable Android based OS?

Hi everybody,
Seems like I posted in the wrong topic (General forum), so I post my question here
I am now using a Galaxy tab 2 P5110, running under Android 4.1.2, not rooted.
My problem is that my Tab is really slow when I use basic apps (chrome, office apps).
In order to get a bit more power from it (removing the Samsung layout, but I know it's a 2012 tablet...) I am looking for the most stable ROM I could use, and if possible running under a quite recent android version.
I am quite new to this kind of manipulations, so I am also looking for a tutorial to instal the ROM you could advice me.
I know I have to root my tab before doing anything. Does the tutorial available here (https://forum.xda-developers.com/sho....php?t=1657056 - by Weltwon) work with 4.1.2 android version?
I have an other question: Is the root enough to remove the Samsung touchwizz layer? If yes, how to do it?
Thank you all for your answers!
Matthieu
------------------
Edit: I have an other question. Is the root enough to remove the Samsung touchwizz layer? If yes, how to do it?

Before you do any of this, check if your emmc is faulty or not by using a brickbug checker app from the play store.
(Requires root) f you want to stay on stock rom but its becoming laggy, trimming the storage would reduce lags. This is because native trim support didnt come until 4.3.
But if you want to move to the latest version of android, most roms posted under the unified section are stable except 7.1 which is still experimetal
--Rooting the tab--
You can use cf autoroot by chainfire but it requires a usb cable, a pc, and odin. Tutorials about this can be found on google. Just make sure you use the right package for our model.
You can also use one touch root apps such as kingroot or kingoroot but they contain bloatware.
And lastly, you can flash a custom recovery such as TWRP using odin and flash supersu from there.
Hope this helps

Thanks you Lightracer!
Do you have an emmc chercher app to advice?
I'm going to read a bit more about rooting ans flashing ROM.
I do not really care about running Samsung Stock ROM or not. My though was to run an Android Stock ROM, without any "layer" (touchwizz, ...), And if possible, the most up to date version.
Is it necessary to enable TRIM if I flash a Android Marshmallow or Nougat ROM ?

Just check "Emmc brickbug check" in the play store.
If you want the stockiest rom, check out the unlegacy project in the unified section. Its AOSP 4.4/5.1 /6.0/7.1 roms.
TRIM is enabled in most kernels. But if you have the emmc brickbug, it might kill your tab X(
Good luck! Also press thanks if I helped ^_^
