Hello. I just ordered my galaxy note 2 N7100 Int. version(not the n7105 lte one). I live in Greece and the phone should have arrived by 15-20 January. Even though I'm not an android noob and im using android for 2-3 years and made my own ROMs as well, I have no clue how Samsung phones work. So I would like a detailed guide please about the steps I'm will mention:
*What is the latest official firmware I can install on my N7100? How can I do that?(I'm not familiar with OTA's)
*How can I root that firmware? What is the best option for rooting it?(chainfire etc but give details on how to do it with those methods)
*Do I need to unlock my bootloader to install custom recovery and flash a rom?If so how can I do that?
*Is Philz recovery fully working and compatible with 4.4+ ROMs? If so how can I install it? If not whats the best recovery with support for 4.4+ ROMs?
*What is the best ROM with the features of Note 3?(stable no bugs good for gaming) How can I install that ROM?
*What is the best 4.4 ROM?(stable no bugs good for gaming) How can I install that ROM?
*How do I backup my IMEI?
*What is the procedure to install a ROM?(on my old phone it was : 1)Backup 2)Factory reset 3)Wipe cache,dalvik cache, system, data, and again format cache 4)Install ROM 5)Install GAPPS and reboot. Done. Are there any differences here?
I wont buy a new phone for the next 1-2 years at least so I wont my new phone to be safe when playing with custom ROMs. If you are about to comment without a detailed guide or at least telling me where to look for that guide dont comment at all, it wont help me.Thanks in advance and sorry for the trouble.
Too many questions to answer and therefore I recommend to go to the Development section for further information. Each Rom has its own install instructions, just read there and learn more about your device :good:
You can't get spoonfed here, sorry mate.
To try to answer just a few... really too many questions, you need to read a bit before posting so many questins
*What is the latest official firmware I can install on my N7100? How can I do that?(I'm not familiar with OTA's)
MKD - Indian, MK9 - european, ML3 - asian. They all work on any int 7100 model.
*Do I need to unlock my bootloader to install custom recovery and flash a rom?If so how can I do that?
You just have to root.
*What is the best ROM with the features of Note 3?(stable no bugs good for gaming) How can I install that ROM?
Most popular are DN3 and Phoenix (also maybe DR Ketan's custom ROM, but it isn't developed anymore). I personaly use Criskelo which is really stable and smooth.
*What is the procedure to install a ROM?(on my old phone it was : 1)Backup 2)Factory reset 3)Wipe cache,dalvik cache, system, data, and again format cache 4)Install ROM 5)Install GAPPS and reboot. Done. Are there any differences here?
In Phils's recovery (I recommend v 5.15, not v 6.x - because of Aroma bug) you do "prepare for ROM flashing" and then flash ROM. Erasing dalvik/system/cache etc can't hurt but is not necessary, all is done in one go. From ODIN - go to download mode, connect to PC, run ODIN and select md5 file to flash.

Hey @dalanik thanks for your quick answer. I have some more questions for you. First of all, are 4.4+ roms stable for this phone for daily use and gaming? Is Philz recovery 5.15 compatible with 4.4+ roms? How do I root my device(latest official firmware) and how do I use ODIN(why is odin needed, what is odin doing)?What about backing up my IMEI? Thanks in advance.
I haven't tried 4.4 ROMs so I don't knpw. As for rooting just have a look at the forum there are several threads on rooting. Odin flashes ROMs.

What should I use to flash roms, odin or recovery(twrp, cwm etc)?
Actually Odin can be used to flash I.e. bootloader which recovery can't. Odon is used to flash official Samsung stock ROMs in md5 format while recovery is used fir custom ROMs mostly with the Aroma installer.

So to flash Phoenix ROM or DN3 or any KK ROM I dont need ODIN correct?
I think if youre on 4.1.2 you need to flash new bootloader. Each rom has instructions so hav3 a look at rom thread

First when arrives your phone see the firmware version, if it has 4.3 and flash custom recovery firmware etc you loose your warranty and for the moment is not possible to take warranty back. If your firmware is 4.1.2 the things are more simple you can flash everything (except 4.3 official bootloader also 4.3 official firmware witch includes bootloader) and have when you need your warranty back.
All your answers are in the forum search for start dr.ketan threads. You can start from here (old thread but very good writed for 4.1.2 there are some differences with 4.3 you have to check before act for example mobile Odin trigger the warranty at 4.3 also triangle away cannot affect knox etc etc)
http://forum.xda-developers.com/showthread.php?t=1896696
he has plenty of guides solutions etc and I think you will find many answers for your questions. Now if your phone is at 4.1.2 firmware and you want to flash 4.3, root etc or 4.3 custom rom (not all) repost to guide you how to flash and also have your warranty back.

Hello @dalanik, @vagsvag I just got my Note 2(Italy version) GT-N7100. Here's the details from the settings menu
*Android 4.1.2(gives me the ability to update to 4.3)
*Baseband N7100XXDMF1
*Kernel 3.0.31-1071214
*Build number JZO54K.N7100XXDME6
The phone is COMPLETELY stock, no root no custom recovery nothing. Can you please give me full instructions on how to install this ROM please?
About 4.4 ROMs, i have tried them.
Things that don't work:
- Bluetooth ear piece???
- Camera is not 100% stable
- I don't have sound when recording videos (Could be just me, no one else is mentioning it )
- Bad FPS in games (tried many kernels and governors, still bad. AGAIN, could be just me, no one else is mentioning it )
And that's it.
For DN3
- Root
- Flash recovery (TWRP my choice)
- Full wipe (data,system,internal storage,cache)
- Flash DN3 (you will now get a bootloop)
- Flash it ONE MORE TIME,
There is something wrong with AROMA installer, if you look closely it doesn't install the ROM for the 1st time, hence the bootloop.
Also, you DON'T NEED TO FLASH the new bootloader. I'm on the DMG1 bootloader and i'm running DN3.
If you don't flash the bootloader, you have to flash the Wi-Fi fix, to get the Wi-Fi working.
You may also experience a reboot once in a week or 2 weeks, it's random.
I personally don't want to flash the BL, because i'm terrified of ODIN. I have a bad history with it :laugh:

@Mashed_Potatoes thanks for your reply but please make things a little bit more detailed..
- Root -- how can I root my device? Link?
- Flash recovery (TWRP my choice)? I want Philz recovery. How do I flash it? Is there any problems with flashing DN3 with Philz recovery?
-What are the prerequisites to get DN3 ROM to work FULLY? Have you noticed any important bugs while using it? What bootloader do I have to flash to get DN3 ROM to work? How can I flash that bootloader? Remember I'm on stock 4.1.2
-How can I access Recovery on this phone?

I don't know about Philz i had it before TWRP but that was before DN3 existed =D
I found no bugs in DN3, its a bit slower than 4.1.2 and the ram usage is higher
You flash the bootloader through ODIN too but i cant help you about that i don't know
Once you root your phone download an app called Quick Boot which will allow you to access Download and Recovery modes with one click
Hey guys I need a little bit more help.
@Androidwizzard @dalanik @vagsvag
I successfully rooted my device with CF and ODIN and now I installed latest Philz recovery as well.
One last question.. I'm now on official 4.1.2(again xD)and like I have said again I want to install DN3 ROM.. What bootloader do I need to flash to get DN3 to work?How do I know what bootloader Im using right now?
What I think the procedure is
1)Install 4.3 bootloader while running 4.1.2
2)Make a backup with Philz recovery
3)Full wipe and install 4.3 DN3 ROM.
Is this correct? Dont forget to answer the other things I asked you!! Thanks in advance!!

There is only ONE bootloader you can flash that is KNOX-Free, and that is MJ5. All other bootloaders have KNOX. Do not use Wi-Fi fix as that will fix your Wi-fi but may introduce instability, reboots, etc. Well, not the Fix, the fix is fine, but the rest of the old bootloader. Just flash MJ5.
I'd do backup FIRST and then flash bootloader.

FIRST of ALL: Don't use the latest Philz, RUN 5.15 is the best way to flash 4.3 custom roms with Aroma installer!
As mentioned: You got to take MJ5 if you ever want to go back to stock 4.1.2 at any time, besides you won't have wifi issue.
Only way to change bootloader: PC Odin.
Befor starting to install a custom rom read the instructions on the OP of the desired rom. There you find all necessary wipes to do :good:

@Androidwizzard so to flash DN3 ROM this is what I have to do:
1)Flash Philz 5.15 recovery with ODIN
2)Flash MJ5 bootloader while running official 4.1.2
3)Make a backup of current with recovery
4)Make the necessary wipes with recovery and flash DN3 ROM
Is everything I mentioned above correct?
Also how do I go back COMPLETELY stock if I ever want?
And btw is DN3 ROM good for games? I play lots of heavy games like GTA:SA etc..
Thanks A LOT guys for helping me, I know I'm annoying but I'm really new to Samsung and this all seems really strange

Here you find all you need from the godfather Dr Ketan:
http://forum.xda-developers.com/showpost.php?p=48032704&postcount=4753
There are several links and guides, :good:
I have an i747M, from Fido (rogers) running the stock 4.3 firmware. yesterday i tried to root it using odin to install CWM, and then CWM to install supersu.
after successfully installing supersu, i restarted the phone, and got knox blocking the app. i updated it from Play, but then i couldn't open it, and it said it can't install the binary. when my phone asked to update the security certificates, i (stupidly) agreed.
i downloaded the .zip for supersu 1.89, and tried installing that, with the same result, but this time i also can't uninstall supersu.
i've bumped my binary counter, but i'm back to basically stock now.
my goal is to install aokp. is there a way to do it without gaining root first?
if i install CWM through odin, can i flash the aokp rom from CWM?
will the phone reset the recovery?
is this risky?
You could try installing a pre-rooted Rogers rom from here: http://forum.xda-developers.com/showthread.php?t=1739426
I was not able to find a pre-rooted 4.3 for Fido and, since you intend to install a custom rom and recovery, the pre-rooted Rogers ROM might be a good place to start.
It's there a reason to install a rooted rom before aokp? As far as I can tell, I can install aokp without rooting at all.
or am I missing something?
Sent from my SGH-I747M using xda app-developers app
Yes, you can just install a custom ROM without rooting first.
I mentioned the prerooted ROM because you post said you wanted to install su.
Ok, please confirm i have this procedure correct:
1. i use Odin to install CWM
2. boot straight into CWM
3. from inside CWM, i flash the AOKP zip file, and then the gapps zip file
my understanding is that this will keep cwm as my recovery and install aokp with gapps.
am i missing anything?

Just make sure you flash a tar version of CWM that is meant for your phone.
I can't really speak about 4.3 because I'm on 4.1.2 but the method you described is the same method I used.

so from what i understand about updating the bootloader to MJB, i can only flash custom ROMs based off TouchWiz 4.3 and up, correct?
but AOSP/CM based ROMs can be any version? as long as the bootloader is supported on that ROM? and worst case scenario, i can flash CM10.1.3 (Android 4.2.2)?
currently i'm on S3Rx 2.2, which uses Android 4.1.2. there would be no point in making a nandroid backup, since the bootloader would be updated and i could no longer use this ROM, correct?
i was going to follow this guide:

then flash the MJB modem via custom recovery with this guide:

reboot to phone (i did, not sure if necessary tho)
then reboot to recovery, flash new custom ROM.
done.
a mistake i did was i only flashed the bootloader first. rebooted, then flashed new ROM. in which case i had no wifi and data. so i flashed the modem, rebooted, no wifi and data still. rebooted into recovery, factory reset, wipe cache, wipe dalvik, and everything worked fine after that.

You could install the MJ2 bootloader and MJB modem which would allow you the ability to go back. Once you are on MJB bootloader, there is not going back without bricking. If you ever find that you need to revert back for any reason you will be stuck. If this does not bother you, then go for it.

i read somewhere that MJ2 was unstable or something. cause it was a preview leak?
but back to my first question, MJB makes it so i can only flash TouchWiz-based ROMs 4.3 and up? so i will be good to use AOSP-based ROMs of any version?
For clarification purposes:
If you upgrade to MJB you will have the 4.3 KNOX apps (OS) and KNOX bootloader (Firmware). You can easily root following this guide: http://forum.xda-developers.com/showthread.php?t=2538991
Once rooted by following the guide noted above you will have the 4.3 KNOX (OS) removed BUT not the KNOX bootloader. With the KNOX bootloader you will never be able to downgrade the bootloader. What that means is that you can never use odin to flash an older firmware or you will brick!
Now that your MJB is rooted you can flash any ROM you want 4.1.2, 4.2.2, 4.3, 4.4.2 since most custom ROMS dont include the bootloader in the ROM package.
Hope this clears things up?

I'm on the latest bootloader and modem and I haven't had any trouble flashing any aosp based roms. Only thing I was told you might have to take the bootloader line out of the update script, but so far I haven't had to at all.

just wanted to clarify, i'm already rooted, so i was going to follow the guide from my first post (since this guide has ZIP files i can flash in CWM):
http://forum.xda-developers.com/showthread.php?t=2321310
Flashing in recovery
If you've downloaded a flashable .ZIP from above, copy it to your SD card or internal storage. Reboot your phone into recovery mode (you can do this by holding "Volume Up" and "Home" while powering on your device; let go of the buttons when you see "Recovery booting..." in blue text in the top left of the screen) and install the .ZIP as an update. Reboot, and you're done.
Note: After flashing in recovery, you need to reboot before you (and ROM installers) actually see the new version number.

would i reboot first, then flash a new ROM?
or should i flash the bootloader, then immediately flash the new ROM?
UPDATE: so i ended up just following the ZIP file guide:
http://forum.xda-developers.com/showthread.php?t=2321310
and now i don't have data or wifi. i flashed the modem from here:
http://forum.xda-developers.com/showthread.php?t=1831898
ANOTHER UPDATE:
after i went into recovery, factory reset, wipe cache, wipe dalvik. the phone is recognizing wifi and data now. woo!
I know there are a few threads regarding this issue but I can't seem to find a definitive answer.
I am currently running stock 4.3 jellybean (rooted). My phone hasn't received the 4.4 KitKat update yet, so I wanted to install CM11 in order to get KitKat on my s3. However, I heard CM11 can be buggy on the s3, so in case things go south, I want to be able to revert back to the stock 4.3 rom. Some people have said that you can easily flash the stock ROM via ODIN. However, others said that downgrading from 4.4.2 to 4.3 will hard brick the device since installing CM11 updates the boot loader. So downgrading to 4.3 stock with a 4.4.2 boot loader will cause a hard brick according to other threads I've seen. My question is, how can I downgrade from CM11 to stock 4.3 safely without bricking? Thanks in advance.
If you are sure you are using a Canadian version of the i747m, you can flash back to stock in Odin using a stock 4.3 ROM for the phone's original carrier (Bell, Rogers, Telus).

Yes I got the phone from Rogers, it's most definitely i747M. But do I have to worry about any issues with the bootloader? I'm assuming installing CM11 will install the 4.4.2 bootloader, so if I choose to downgrade to the stock 4.3 rom, will it cause any issues seeing as I'm running a 4.3 rom with a 4.4.2 bootloader? I just want to make sure because I heard it can cause some serious problems if the bootloader is newer than the rom.

I have never come across a custom ROM that touches the bootloader. A compatible bootloader has to be loaded on the phone before you attempt to install the custom ROM. Supported bootloaders can be found in the ROM's updater script.
I assume your phone has no warranty since you rooted it on stock 4.3. Did you root it by installing a pre-rooted ROM?
You could copy a ROM to your external SD card, install Philz Touch via Odin, reboot directly to recovery, create a nandroid backup, wipe cache, Dalvik, data, and install your KK ROM.

Okay, I was just making sure because I know OTA updates can change the bootloader, so I just wanted to make sure the custom roms don't do that. As for the custom recovery, are you recommending Philz Touch over CWM and TWRP? Do you know which custom recovery is installed from the CM installer?

Oh and one more question, my phone was originally carrier locked to Rogers and unrooted on 4.3 jelly bean. I brought it in to a cell store for them to carrier unlock it for me, but they used a rooting method to unlock it (because SuperSU was installed on it when I brought it back). They didn't unlock it with a code, so I'm guessing they used something like Samsung Tool or z3x shell. If I install CM11, will I lose the unlock, considering it's more of a "soft unlock", or is the unlock permanent regardless of how many roms I flash? Thanks for your help!

Philz is based on the latest release of CWM and I prefer CWM over TWRP because I had problems flashing ROMs. Once I switched to Philz/CWM, no more problems.

The unlock should be permanent. I unlocked it using the free method when on 4.1.1 and no ROM has ever caused it to re-lock. Reflashing a completely stock ROM, including the bootloader, did not relock the phone.
Please remember that flashing and changing ROMs will always carry a risk of soft bricking or hard bricking your phone. Make sure you read all of the guides and be prepared for disaster.

New Phone, Who dis?
Hello, Huskied here, And I am requesting help installing this Nougat safely on this Galaxy S4 on T-Mobile.
Keep in mind, This is still on 4.4.4 KitKat, Haven't installed an update just yet, unrooted, and it's a SGH-M919 type.
Build Number KTU84P .M919UVUFNH7
any help would be appreciated.
Here's what I would do:
Flash the latest stock ROM from Sammobile.com with Odin;
Flash twrp for the m919;
Save the rom and appropriate gapps to the phone's internal storage or sdcard; and
Flash the custom ROM, flash gapps, reboot.

Thank you. And one more thing, Some ROMs require LP Bootloader. Where can I get that?
Flashing the latest stock ROM will give you the latest bootloader.

Tried today, Couldn't find any stock ROM for the jfltetmo. Found a bootloader that's supposed to boot the ROM I would like, Failed and could only boot into recovery until I restored 4.4.4.
Any thoughts?
If the phone baseband is running these latest fok3 ROM, that is the newest bootloader for the phone as indicated here: https://www.sammobile.com/firmwares/galaxy-s4/SGH-M919/TMB/
Btw, that nougat in the original is not for the m919 so don't flash it as it may hard brick phone.
