[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Apologies in advance if this has been covered already, but I did quite a bit of reading up and the information seems to be quite spread out and slightly different over the years for different Samsung devices so I wanted to just double check my understanding for the Note 4 before I proceed.

I have a Note 4 purchased from O2. I have had it unlocked to all networks via a code requested from O2. Now I'd like to install the stock UK BTU firmware.

My understanding is that I can flash the BTU firmware using Odin without having to root my phone.

The part that I'm unsure of is what the situation will be with regards to OTA updates, will I definitely not get any notifications of OTA updates after flashing BTU? Or is there a chance flashing the BTU firmware will update the CSC without me having to root my device?

If I definitely won't get OTA updates, will flashing future BTU updates via Odin require me to lose any data and/or need to do a full reset of my phone? i.e needing to reinstall apps and restore SMS/etc. from backups?

Any help on this would be greatly appreciated!
[Galaxy Note 4 Q&A, Help & Troubleshooting] martytarty:
When Flashing Stock BTU you will not lose any data, you will only lose data if you choose to perform a factory reset, if you have sd card that data will also remain safe. As you are wanting to debrand it will require a factory reset :(

In regards to OTA updates you will still get them if you have debranded correctly and removed the o2 csc code.

So you say you have it unlocked, next step is to flash btu firmware, once flashed you then need to perform a factory reset (removes o2 csc code and adds generic code so the updates come from samsung)

If you have followed the above you will have a debranded phone that will get ota updates when they are released by samsung.

If you ever decide to root then you would lose ota updates (however there are mods to overcome this) this would mean you need to flash the new updated rom, when flashing new stock rom you would also lose root meaning you would then need to re-root your device.
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Perfect, thanks! I don't mind having to do a full wipe just now after flashing BTU because I haven't started setting up the phone/installing apps/transferring my data yet. It was more to check that for future OTA updates I won't need to lose data in order to install them.

So from what you've said, if I do a factory reset after flashing, the CSC will update to BTU and I can then get OTA updates for BTU as normal? That would be ideal as I don't want to root at the moment (due to Sky Go, banking apps and my corporate email client)
[Galaxy Note 4 Q&A, Help & Troubleshooting] matw01:
Do you need to unlock before debranding?
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
I've seen some posts that suggest that you do, but I'm not sure.

In my case O2 provided the unlock code within a few hours so I made sure to unlock my device first, will flash the BTU firmware onto it tonight as the download from SamMobile was going pretty slowly for the 1.5GB file.
[Galaxy Note 4 Q&A, Help & Troubleshooting] matw01:
I debranded my note 3 without unlocking, not tried debranding my note 4 yet although I'm tempted as I would like the battery update and any others a little more promptly.
[Galaxy Note 4 Q&A, Help & Troubleshooting] martytarty:
Yes you can flash btu without unlocking which would debrand your phone however I dont think you will get ota updates as your sales code (csc) will remain linked to your carrier, you would need to do a factory reset to change the csc to generic BTU but this might conflict with the fact the phone is not unlocked, I got my unlock code from o2 the same day I purchased my note 4.

Unlock phone

Flash btu

Factory reset

Done
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Thanks again martytarty for the info. I managed to flash BTU last night.

In case it helps anyone else, after the factory reset I had to boot to recovery a few times before the message at the bottom of the screen confirmed that the multi-csc of BTU had been applied (the first couple of times it kept saying it had applied O2U)
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Oh yeah, and today I did an OTA update check on the phone and got the 1.23MB second update for BTU and it downloaded and installed without any issues.
[Galaxy Note 4 Q&A, Help & Troubleshooting] martytarty:
No problem, mine went to btu first time after flashing/factory reset, glad it's all working for you :good:
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Yup, all seems to be fine now.

O2 tried to be cheeky when I called up to pay off the device plan and cancel the airtime, saying I must pay for one month of service. I made the device payment over the phone and then went onto the online chat to speak to someone about the airtime cancellation. They confirmed that I could cancel immediately and only pay for the days used so I did that and have saved a copy of the chat log in case O2 conveniently try to charge me the full amount anyway.
[Galaxy Note 4 Q&A, Help & Troubleshooting] martytarty:
So you took out a contract with o2 to just get the phone? then just pay off the device so your out of contract?

I'm been with o2 for nearly 5 years now, I'm happy with my overall service with them so have no reason to leave, refresh is a good idea also, I take it you could of purchased a sim-free version outright but didn't want to wait?
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Yeah, pretty much. I wanted the handset on Friday and everywhere else was either sold out (Samsung Store, Three) or refused to sell me one on their pay-as-you-go rates (EE). So I walked into O2, got a contract (£70 up-front and 24x £20 handset plan, plus £28 airtime plan). So given that I've cancelled the airtime within the cooling off period and O2 gave me the unlock code for free, the handset cost £550, which is cheaper than anywhere else at the moment. Plus I have it right now rather than hanging on for a pre-order from Clove.
[Galaxy Note 4 Q&A, Help & Troubleshooting] laxity:
OdieS, could you point me to the SamMobile dowload you used for BTU please? I bought an Note 4 from O2 today and I want to flash this to BTU. Just want to make sure I use the same one you did as yours was successfull. :)

Also did O2 charge you anything to unlock? Did you just phone O2 customer support? I've had problems unlocking my S3 in the past with O2 and them never sending an unlock code.

Cheers,

Richard.
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
This is the one I used: http://www.sammobile.com/firmwares/download/36857/N910FXXU1ANJ4_N910FBTU1ANJ1_BTU.zip/

But this is appears to be a slightly newer one now: http://www.sammobile.com/firmwares/download/37226/N910FXXU1ANJ4_N910FBTU1ANJ2_BTU.zip/

I think you can use the older one and see if you get the very small update via OTA once the CSC has updated to BTU on your phone after the factory reset.

I requested the unlock code via the form on the O2 website the same day I got the handset (Friday) and received the unlock code by email the following day (Saturday). But bear in mind that it does say up to 72 hours (or sometimes even longer), so they do cover themselves for delays.

I have read that some people have managed to get the unlock code from the Customer Services phone line but I didn't try this. The link to the O2 unlock form is on this page: http://www.o2.co.uk/help/phones-and-devices/unlocking-your-iphone-and-using-it-on-another-network

There was no charge for the unlock code.
[Galaxy Note 4 Q&A, Help & Troubleshooting] laxity:
Great thanks for the info and the links. Reading the site it looks like I might have to pay £15 to unlock as I bought my phone outright (which required me to buy a £10 pay as you go sim). I am on O2 already but wanted to keep my O2 contract as it has unlimited data for £20 a month. I suspect they won't accept my contract phone number as it was bought with the pay as you go sim. I'll give it a try with my contract number though and see what happens :)
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Not to go too off-topic, but what did they charge you for the handset?
[Galaxy Note 4 Q&A, Help & Troubleshooting] laxity:
Was £609.
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
Ouch! It was £69.99 + 24x £20 (£480) on the 20GB Refresh contract = £549.99

Change AT&T To BTU

Hi guys, i know this is probably a stupid question, but i'm trying to debrand my AT&T Note 4 - N910A to stock BTU firmware. Is this possible as i keep getting a FAIL in ODIN.
[Galaxy Note 4 Q&A, Help & Troubleshooting] OdieS:
I don't think BTU (UK Unbranded) firmware will work as it's designed for the N910F model.
[Galaxy Note 4 Q&A, Help & Troubleshooting] hipwell:
has anybody tried this without unlocking? Seems to be mixed opinions on this. I want to debrand but vodafone wont give me an unlock code
[Galaxy Note 4 Q&A, Help & Troubleshooting] joe_tilley:
Thanks very much for the reply, do you think the only way to do it would be to modify the CSC and then try to flash the firmware file? Or are you aware of a US variant firmware I could flash?
[Galaxy Note 4 Q&A, Help & Troubleshooting] :
The at&t has a locked bootloader so rooting and custom roms are out of the question. I suspect you will not be able to Odin anything except the official firmware for your device and not sure even that will be possible
[Galaxy Note 4 Q&A, Help & Troubleshooting] jshq97:
Hi, I thought I would revive this thread as nobody seems to have provided much information on the situation with debranding while the phone is still locked.

I can confirm that you can debrand the Note 4 without having to unlock it first. I have the N910F locked to EE and I flashed the BTU firmware. I did a factory reset/wipe data and clear cache and rebooted into recovery, this changes the CSC of the phone (mine changed from EVR to BTU) when booted into recovery after doing those steps. I downloaded the BTU firmware (4.4.4, the latest as of posting this) from Sammobile, and flashed in the normal way with Odin.

P.S. As this is a stock official rom, The knox/binary counters haven't been tripped. The stock BTU unbloated rom is much smoother than the carrier versions. Just waiting for the Lollipop OTA for BTU (UK) to be sent out :)

[General Questions and Answers] imamul.karim:
I have an android phone. which is not a famous branded company. you know there are many china company who are also produce

android phone. and there is no custom ROM available for those phones.

so, i want to know. for what parameter or configuration i can choose a custom ROM. so that my phone is not going dead.
[General Questions and Answers] xdauserame:
some little help

I'm from China and I know how crappy their phones are. The first thing you need to check is your system. Go to settings --> about check your android system version. If it's 4.X, you are lucky. If it's 2.X, your choices are greatly limited.

Then, check your ram. Mondern or newer systems need more ram. a small ram will lag your system and apps.

Personally, I recommend CyanogenMod http://www.cyanogenmod.org

They do mods based on original Android made by Google.

look for a model whose specification is similar to your device and download. It may work.

Anyone got a fix for the storage card issue on WM6? I have 26MB free until I plug my card in and then it drops to 18MB free program memory...
[8125, K-JAM, P4300, MDA Vario Software Upgrading] papizdono:
i have 27,4 megs free and after plugging in sd card i get 25,2 free...

dont think thats an issue
[8125, K-JAM, P4300, MDA Vario Software Upgrading] brooks.nl:
free megs

without sd-card 29.7Mb

with sd-card 29.1mb

both after softreset

so indeed i don't think its is an issue. you might have a couple of programs installed on the sd-card instead of installing it on your wizard
[8125, K-JAM, P4300, MDA Vario Software Upgrading] papizdono:
yea, i have photo contacts pro installed, that takes about 2 megs of ram , so its almost the same probalbly.... well working good after a week, Rom is loved :D
[8125, K-JAM, P4300, MDA Vario Software Upgrading] DoctorT:
I had that issue with faria's AKU3.3 (5MB less with card inserted) - no issues with WM6 for me...
[Nexus 9 General] EverythingPortable:
Many already know that this device will be very good to run different emulators with.

Everything from Dolphin to Drastic DS, Reicast, Mupen64 and many more. I'll focus a lot on Dolphin as thats the emulator that will get the best boost compared to the Tegra K1 32-bit.

[Nexus 9 General] NZtechfreak:
Look forward to seeing them, since I won't be getting my own N9 at release. I don't really care about seeing anything but PPSSPP and Dolphin though, since the others are already fine on older hardware.
[Nexus 9 General] tyvar1:
I hope that PPSSPP and Dolphin will work good :)
[Nexus 9 General] EverythingPortable:
I think PPSSPP will run almost all games at full speed. But running dolphin at full speed will be much, much harder to achieve. Hopefully we will see at least 50% gain in fps compared to the shield tablet.
[Nexus 9 General] mk92595:
Not really interested in emus since I have a Wii U for that but I expect the N9 to run anything you throw at it
[Nexus 9 General] roninmedia:
I have PPSSPP running Tactics Ogre: Let Us Cling Together and Final Fantasy Tactics: War of the Lions running fine on a FireTV and Galaxy Tab 2 tablet fine. I'm also playing around with a few Japanese visual novel imports. PPSSPP should not have any issues on the N9.
[Nexus 9 General] tyvar1:
You need to remember that this tablet is rocking a QXGA (2048x1536) screen so it will be more heavy to play on it :)
[Nexus 9 General] USBhost:
Thats where overclocking comes in
[Nexus 9 General] NZtechfreak:
That won't tax it harder on Dolphin per se, since it won't be rendering at that, i wouldn't expect it to run well except on 1xIR (the Dolphin native resolution).

The Nexus 9 certainly won't be able to manage "anything you can throw at it" though, since even the most high spec PC can't do that right now and maintain full speed on certain games in Dolphin. My i7 4790K with water cooking and overclock and GTX 980 SC ACX 2.0 can't, and that's much more powerful than the K1.
[Nexus 9 General] tyvar1:
Ooo yeees! :D
[Nexus 9 General] dianestory2:
I mostly emulate on my nexus 7----does anyone know of a good way to emulate gamecube games? I would love to do that...
[Nexus 9 General] NZtechfreak:
Dolphin is the Gamecube emulator, but never going to playable on the Nexus 7.
[Nexus 9 General] dianestory2:
Would it work on the nexus 9?
[Nexus 9 General] NZtechfreak:
That's the question we're all waiting to have answered!

So far the Nvidia Shield Tablet, by far, runs it the best and the expectation is that the K1 Denver should be a good step up from there as it nearly doubles CPU performance, which the emulator is more dependant on. I would expect many games to still run slow, but a good deal more titles should be playable (more easily emualted games like Timesplitters 2, which runs at about 40-45fps on my Shield tablet and might be fully playable on the Nexus 9).
[Nexus 9 General] dianestory2:
OOOOoooooohhhhh sorry, my bad, I'm used to people on here knowing everything hahaha sorry ;)
[Nexus 9 General] EverythingPortable:
Dolphin only uses 2 cores, that means that dolphin is not taking advantage of the full power the shield tablet has. Nexus 9 is running a dual core k1, and the single core performance is up to 100% faster than the quad core k1. This should give us a big speed improvment in dolphin
[Nexus 9 General] Rage1ofakind:
I'm currently running DraStic on my Samsung Tab S 8.4, and it works PERFECTLY. Soooo smooth, best DS/3DS emulator out there. Looking forward to using it on the Nexus 9, with what the wider screen.

(PS. Got the emulator for Pokemon :cool: . you're never too old for that game :o)
[Nexus 9 General] Gormsen:
You're right mate. Most of the games I play are older Pokemon games, from when I was a child or hacks based on those games.

Not sure if I find the huge screen preferable for GBC and GBA emulating, but I'm really looking forward to pushing that soc to the max :P

Truest thing ive heard all day:good:
[Nexus 9 General] mk92595:
3DS emulation is possible?
[Nexus 9 General] Gormsen:
Nope, that's not even possible on a PC :(

[Nexus 9 General] Rage1ofakind:
Not all of them, but apparently they got some 3DS games to work as they started development on it around September (2013). Have not tried playing any 3DS games myself. If you can link me up with a couple of different 3DS roms, I can get it up on my tab and see if they work.
[Nexus 9 General] tyvar1:
Pokemon Light Platinum is a great Pokemon hack :D
[Nexus 9 General] EniGmA1987:
Why would we get an instant boost for emulators between this an the 32-bit K1? That makes no sense at all because the app must be coded or at least compiled with 64-bit in mind to actually make any use of improved processing capabilities.
[Nexus 9 General] USBhost:
Like what google said

if an all java app gets installed it get compiled to 64bit
[Nexus 9 General] dianestory2:
Where do you guys get your games that you emulate? Are they all illegally downloaded? (no judgement) Or do you actually pay for them from somewhere?
[Nexus 9 General] USBhost:
well for some there is no way to get them other than illegally
[Nexus 9 General] dianestory2:
I'm presently unaware of a legal way to get them. Like I said, I'm just asking, out of curiosity. I guess illegal downloading has always worried me; not that I mind about the morality, but I get nervous that a police officer is going to come knocking on my door to take me to jail or something. Is that an unrealistic fear?
[Nexus 9 General] MRobbo80:
Ask no questions get no answers, you do realise members can not possibly comment on this right? After all this is a developers site. Will you go to jail just for downloading a couple of games I guess if you did you had some really really bad luck!
[Nexus 9 General] EniGmA1987:
There are quite a few ways to get games for the emulators legally, or semi-legally, depending on your countries laws.
[Nexus 9 General] USBhost:
correct me if I'm wrong

in the us

is not illegal to download a game that's the copyright is 10 years ago
[Nexus 9 General] NZtechfreak:
Try reading the thread, this has been covered.

---------- Post added at 05:37 PM ---------- Previous post was at 05:24 PM ----------

Regarding obtaining the ROMs:

Firstly, I own every system I emulate games for, and I only play games that I own. Let me quite clear about that, I don't condone emulation as an avenue to piracy. On my Note 2 connectivity video on YouTube I make a point of showing the discs/carts or having them on display in the background, just to head off the inevitable accusations that I'm not being truthful here.

I use Rawdump to rip my Gamecube and Wii discs, you need certain models of DVD drives for this to work however as they had a particular firmware that allows the exploit Rawdump uses - check the Dolphin forums for more on this. You can pick up one of those drives readily from EBay/Amazon etc. Alternately you can do it from a modded Wii.

In many legislatures this is legal, as many countries grant the option to make a single backup of copyrighted software you own.

For me personally I'd much rather play GC and Wii games on my PC at 1440p (and later 4K when the right monitor comes along) with 4xFSAA and 16xAA, than drag the old system out and play them at the horrible native resolutions on offer there. I use a real GC controller via a Raphnet adapter, or WiiMote via the Dolphinbar, so the experience is awesome.

Incidentally, the Gamecube controller works with my Nvidia Shield with that same Raphnet adapter, hope Google doesn't screw over USB OTG on the N9 as they have tended to do in the past.
[Nexus 9 General] hyZar:
If I recall, it is not illegal to play emulated games if you already own the game. Or you can just not care, either way....

I am curious to see if the N64 Emulator would work on the Nexus 9. Would it be powerful enough you think?

Are you serious?

That's been possible on Android for a few years already, so jump on in!

Just tried the dolphin emulator.

The emulator itself was realy laggy.

Tried to map some buttons. Constantly crashing.

Dont know if its a lolipop isseu or app related.

Then i tried running smash bross melee.

Got it working but with alot of lagg.

:(
[Nexus 9 General] dianestory2:
Major bummer.... Maybe it will get better with a little time... :(
[Nexus 9 General] pantmunu:
Those emulators probaly need to get updated first. I guess .. in order to run properly and without lags.
[Nexus 9 General] NZtechfreak:
Which version of the emulator though? Previously the Play Store version lagged behind the developer version by more than six months.

Just the one game, or others too?

Not sure if current builds have been worked up for ART.
[Nexus 9 General] berendspruijt:
Used version 0.14

Only used smash bros.

Dont have any other games atm
[Nexus 9 General] NZtechfreak:
Checked that and I see they finally updated the Play Store version, not sure which dev build that correlates too, but I guess the Play Store version not so far behind at present.

Presume you changed it from Software Rendering to Open GL in settings?
[Nexus 9 General] EverythingPortable:
