Good afternoon folks. Im a fairly experienced guy as far as rooting and installing custom Rom's go on Samsung Phones. In this case I have POSSIBLY, the Hong Kong version of the Samsung Galaxy Note 5 (SM-N9200) and while I was able to get a root on it with King Root..it's not my desired method. I'd really like to ROOT the phone, but I need to first unlock the BOOT-LOADER.
I've tried the CROM-APK but it won't install (I Keep getting "App not installed" every time I attempt it), and to my knowledge, I don't know of any other methods. IF anyone has a SHORT or LONG winded manner of doing this it would be appreciated. I've even tried the ONE-CLICK-ONE-TOUCH all the way around method and that was to no avail as well.
Also does anyone know if this phone is LTE Capable???? Would flashing a custom Rom give me access to that feature?
Any help would be appreciated.

Hiya all! I was hoping i could get some advice on your recommended method for rootng my new S5. I havent done a root since i bought my s4 over a year ago, so i wanna get up to speed on current rooting. I already tried the Towelroot and it doesnt work on my phone. Im guessing my phone came preloaded with the update that breaks towelroot. I tried the tricks with changing the number values in Towel by tapping the screen 3 times , but none of them worked, they all say my phone isnt compatible. So id like to know a few things. A: which root method do you wonderful XDA peeps recommend i use? and B: what would u recommend i do to remove all the annoying bloatware and such? Its been a while for me, so i didnt wanna rush headlong into this without getting a professional opinion first. Perhaps theres a good custom Rom i could flash?
Thanks!

Thanks ! That was a breeze! phone has been successfully rooted! Any recommendations on what to use to remove all the bloatware and crap? Im considering trying a custom rom sometime, but for now i at least wanna clean this up and get it running better with more storage space!
Hi xda
I have referred to this site many times for help but never became a member until now - I seriously need some help!
I recently bought a second hand S3 LTE which I knew was locked but as I had unlocked a few phones in the past I thought it wouldn't be a problem... until I encountered Android 4.3 and its bodyguard Knox. Searching on forums I found many other people experiencing similar problems but nothing conclusive that didn't involve using a Z3X box which costs about as much as I paid for the phone.
Apologies if this has already been covered in some form in another thread but I have done a lot of searching and a lot of hair pulling before coming to this stage.
So to cut a long story short I managed to successfully root the phone using CF through Odin and installed the version of SuperSU capable of bypassing it (downloaded .apk as opposed to play store which some people had said worked).
Next stage was to remove Knox, I installed NoBloat Free as suggested by someone in another forum and I basically removed anything with the word Knox in it and that seems to have done the job.
Now I just need to unlock the damn thing! While I have had some experience with rooting / unlocking a few android phones etc I really don't have much knowledge on the subject and pretty much forget it all in between phones :silly:
For the record I don't care about warranty, flags etc and am more than happy to downgrade if it means getting the phone working.
Any help would be greatly appreciated!
[A] Need help unlocking S3 on 4.3
Hi. The only way I know is via 4.1.1 ROM as explained here: http://forum.xda-developers.com/galaxy-s3/help-i9305/sim-card-unlock-samsung-galaxy-s3-gt-t2185866 (no root needed, just install the 4.1.1 using Odin)
I recently unlocked a stock 4.3 I9305 downgrading it to 4.1.1 first. It worked fine and then I restored a Cyanogenmod 4.4.4 ROM I had from another I9305 of mine. And then on CM I "lost" the IMEI (it happens), but I easily recovered it.

So I actually don't have the S5, or any Samsung device for that matter, but a friend of mine does, and really wants to root their phone. I had no idea the AT&T S5 was so secure, but it's pretty interesting too. I've been researching for over 15 hours. I may not have been able to root his phone, but I think I have learned a couple things and maybe some possible root methods.
1.) Since using ODIN to downgrade would soft brick the phone, would it be possible to download the stock Lollipop update onto a computer, give the update super user access, replace the recovery with a custom one, or unlock the bootloader from the computer, then flash it through ODIN?
2.) Intercept any sort of OTA update, then alter it to flash a custom recovery or unlock bootloader? I don't know how you would go around this though.
3.) If someone hasn't taken the OTA update that patched the Stagefright exploit, could someone purposely use the exploit to allow installation of a custom recovery or even to unlock the bootloader since the Stagefright bug has super user access (or so I've heard).
Also, I'm sorry if these are stupid ideas. I know close to nothing about Samsung so everything I'm basing this off of is what I've read in the past 15 hours.

The issue is that AT&T (and Verizon) use an encrypted signature key to verify they are the correct unaltered files as well as the means to unlock the bootloader to allow the OTA. Without that key, the tasks you mention are near impossible. They are not stupid ideas at all..just very difficult with all the security checks included.

Crap... well does anyone know how that encyption key is generated? Like, could I theoretically get an algorithm from a ROM?
Honestly for the time being I wouldn't bother with ROMS for that Device and carrier at the moment. Especially being that its someone elses device. Towelroot should be a good start. If Im not mistaken I don't think its supposed to trip knox.

This is the riddle of the Sphinx my friend. I am sure the super devs have tried their best so far to crack it. It has been an ongoing effort to make phones more and more secure, not against the amateur developers and rooters, but against the hackers. These smartphones are now our personal computers, diaries, personal assistants, financial operator, and more. They basically are a person's (and business's) life. AT&T and Verizon have taken the big steps to appeal to the Exchange clients, corporate, government and military contracts. Even the general public want to know their phone is secure. This is what keeps me stuck on the Sprint network.
Have you tried Kingroot?
I successfully rooted my wife's AT&T S4 on OC3 lollipop (supposedly unrootable) with the desktop version. Mobile version didn't work but desktop did without a hiccup. Maybe it'll work on the S5.

Rockin' a l337 with Goldeneye v49.1 + Wanam Xposed and loving life on AT&T's 4G LTE network
S5 on lollipop has a new nasty boot loader.... it was a miracle on its own that they ever came up with safestrap to duck the boot loader on earlier versions of android
I have the AT&T Note 8 variant. I have installed the latest updates for the device. As I understand it, that makes rooting more difficult. It's been a while since I installed any ROM. I believe I must still root before I can install a custom ROM. What are the steps I need to take with that being the case?
Are there really no custom ROMs for the N950U? I looked through the ROMs section, and every single one of them seemed to be for the other variants.
Thanks for all pointers.
More difficult? There is no current root method if you've taken the update.
Flash ROM's? Do you know how to unlock the bootloader? I know of about 50 people that would pay good money to learn how to do that.
Start reading this thread. It will get you caught up on the status of root for the Snapdragon variant as well as all of the pitfalls.
Thanks. Will do.
Hi everyone, I'm a newbie who don't know a lot about root and upgrade.
I have a Samsung Galaxy Note 3 SN-N900A (AT&T unlocked) and my battery is draining way to much energy.
I looked over the internet and I think it might help if I change my plateform.
So I'd like to root the cellphone but I cannot figure out step by step how to do it.
After rooting, I wonder if it would help to upgrade to marshmallow or nougat without all the draining useless apps from AT&T.
I saw some post about it but I don't know how to use Odin, how to downgrade to android 4 to root or anything else for that matter.
I'm kind of desperate.
Thank you !
The bootloader on this phone is locked and cannot run a custom ROM unless the custom ROM is based on a stock Samsung ROM.
How old is the battery? When did this start happening?
You're not going to like this, but....

mauvaiscell,
You are on a obsolete, dying platform. Your best solution is acquire a new device, if not new at least recent enough to run contemporary software. The latest stock ROM for the Note 3 is several generations behind, and will not be updated. Since many of the later apps no long run on that ROM, or at least not to their full capability, the best answer is get a replacement.
But don't discard your Note 3. Within limitations it is still a beast. Use it to learn about ROMs, apps, etc. You are obviously a smart guy because you know where to look for answers. All you need do is look a bit deeper. All the answers you need are on this forum. Start by reading about SafeStrap, rooting exploits, and custom ROMs. READ, READ, then READ some more. Once you're confident, and have all the tools at your disposal, then start experimenting with your Note 3.
Best of luck.

In tons of forum post that I read so far (as a newbie), this was the most satisfying one ty so much! I'm struggling for 10 days to install a brillant custom rom (ie lineage ) i have only come to try with boot with safestrap recovery and error with it till now.
I gave up tired and the only thing i dont want is a brilliant Rom no longer, it's just an unheated battery.
