Question

Hey guys,

I have a question: which model (Exynos/Snapdragon) offers more variety and quality when it comes to custom roms?

I've read some speculation here and there, and being a newbie in the whole android theme I cannot actually confirm any of it,

so if anyone could conclusively say which one has more going for it here on XDAdevelopers, it would be awesome.

To give a little bit of background though, I'm looking to get the best all-round smartphone that is currently available, and

as it appears that the Note 4 offers the most for the money. The only thing that's of concern to me is Touchwiz, which is why

I'm here, doing my research before buying.

I visited an official Samsung distributor to see how the Note 4 feels, and I was stunned by the display the second the consultant

put up a 4k video to show it off. The design is very solid, especially compared to the older note 3 and S4/3, which kind of looked

like those fake phone toys at the side of the latest models. Unfortunately, in the little time I had with the device at the store,

I noticed the frame drops, lags and other OS inconsistencies, which instilled doubt in my device of choice. The iphone 6/6+ on

the other hand, were a night and day difference in comparison, the fluidity and attention to detail in the software department

were much more satisfactory. Needless to say, the screen and the camera didn't make as much of an impression, and to say that

it is overpriced would be like not saying anything.

If you've read all that you can see where I am coming from with the first question. I hope that there's a way to make android

a good experience too, and if it is achievable within the Samsung array of devices, without compromising on the features

(Spen, HRM etc.), it would make the Note 4 the device to have. That said, there's no way I'd make it by myself in this sea of

information, so guidance is very welcome. To reiterate, I am new to this, so If I'm posting at the wrong thread, or if I should

make my own, do tell.

Thanks, that's a big plus towards the SM-N910C.

I have been told that when it comes to custom roms, the Exynos is at a loss. Is that still the case?

Guys your gonna find this really weird. I really did confirm that it isn't a clone. Here's the thing, today I came across a note 4 from an authorized distributor of the product with the model no. SM-N910F and clearly marked as the Exynos 5433 version. It is clearly marked made in VIETNAM. Anyone come across this so far and possibly shed some light on this?

[Galaxy Note 4 Q&A, Help & Troubleshooting] duvalbmarley:
There is no exynos F model
[Galaxy Note 4 Q&A, Help & Troubleshooting] Kernel ranger:
I know how you feel about an Exynos F. Quite frankly I feel the same way but I can't help thinking that something is missing somewhere because it was stocked in the very shop I bought my S4 which had full 2 year Samsung smartcare warranty (I know this because I sent the imei and the warranty was activated). I could have taken snaps but already sold my s4 because I now want a note 4. I haven't bought it because it's strange to me. What I know is the exynos C as the official exynos not F. It's not even here (world official note 4 listing):-

I have done some investigation on the SM-N910F exynos and it has panned out to be a mediatek device = phake/counterfeit/1:1clone/chinese knock off.

Beware, I have noticed that there is a highly aggressive strategy by counterfeiters to lure you into buying a phake Note 4. I have not seen any other phone that has been soooo counterfeited like the note 4 so far. Even Zedomax gets conned here:- (https://www.youtube.com/watch?v=f5wctoqYkpk)

SM-910C UK registration and support

Just got off the phone to samsung uk about getting the above model registered online which i couldn't due to the model not been in there list and they confirmed not only that i couldn't do that but there was also no uk support for that model!

Also that doesn't seem to be a 64 bit lollipop official roms out there main reason for buying this seems to be scuppered.

It would be nice if samsung had a worldwide warranty support as you could buy the phone in another country and settle in the uk and not be supported which seems rather harsh don't you think?

My n910f bit the dust recently and we have managed to get hold of a brand new n910c mainboard. We're going to see if it fits inside the n910f. If it does, I maybe the only owner of such an hybrid.

I just hope that when it comes to installing firmware it doesn't mess up with OTA missmatches

when i try do enter bootloader it goes strait into HBoot with the only option to reboot.

What can i do from here?

no i only can use reboot it skips the section where you can select. s-on btw
[One (M8) Q&A, Help & Troubleshooting] xunholyx:
Hold the power button + vol. up for about 20 seconds, or until your phone reboots.

As soon as the screen goes blank, slide your finger down to vol. down and hold that in.

You are now in fastboot.

You can also hold power vol. down during the reboot.

The first way is like a battery pull and helps clear some stuff up sometimes. It's the equivalent of a battery pull.
[Verizon Galaxy Note 4 Q&A, Help & Troubleshooting] RobFreundlich:
My wife just got a Verizon Note 4 to replace her slowly dying Note 2. She doesn't use it in a business environment, so she neither needs nor wants Knox anywhere it (obviously she can't get rid of the bootloader lock, but she doesn't want the Knox service or the app). She can force stop the service, but it comes back.

Since she got the phone, she's been getting notifications telling her to take security updates. She's concerned, of course, that they'll turn on Knox, make it more intrusive, or something, so she won't take them. But they come up pretty frequently, and are annoying as heck.

We found instructions for uninstalling Knox Personal on a Jellybean device (http://www.samsung.com/us/support/howtoguide/N0000005/13093/159642), but it involves actually running the Knox app, going into Help -> About, and choosing Uninstall. Naturally, she's loathe to do that - it feels wrong and unsafe to run the very app you want to get rid of in order to uninstall it. Plus these instructions are specifically for JellyBean and the Note 3, not KitKat and the Note 4.

So ... does anyone know what the reality is?

Thought is was supposed to be system? Also the unbricking guide from Dell pdf has corrupted files. But I will try and do boot and see what happens.

Edit: no change. Flashed boot.img and then did a factory restore. Now it's boots to a black screen, like it's looking for an OS. I guess I really screwed it with the flashing the system.img.gz.

You need to download this .tgz from Dell to unbrick A150:

There are some other unbrick files (for A195 I think) that are broken. I emailed Dell about it, but got no reply so far. Just start completely over, following the Unbrick guide. I've done it many times on my Venue 8 3840, and it works fine.

In order for the rooted boot.img to work, you need to end up with your tablet having the IWFI, DNX, and droidboot from the Linux kernel package that Dell provided. You also need the 4.4.4 system.img, which can be obtained by following the unbrick process, and then letting the tablet OTA to 4.4.4. If the unlocked IFWI, DNX, or droidboot are not flashed, then the tablet will not run fastboot, and you'll either get a black screen with a USB symbol on it, or it will boot into recovery.

[Dell Venue] hharte:
I've seen that many times as well. One of the most frustrating parts for me working with this tablet was that error! The following seemed to work for me, but I figured it out towards the end of my adventure with this device, so I didn't get to try it repeatedly to see if the behavior is consistent:

Note on XFSTK: if you have trouble getting XFSTK to download properly, try:

Turn off the device (hold power button for 10 seconds.)

Press the Start Download button in XFSTK.

With USB cable connected, turn tablet on with Power + Volume Up.

I'm also using Windows 8.1 64-bit (on a Surface Pro 3.) I've tried both the built-in USB port and also each of the ports (USB 2.0 and USB 3.0) on the Surface docking station. The port doesn't seem to matter, nor do the cables. What definitely doesn't help is rebooting your PC, reinstalling the drivers/xFSTK, etc. I tried those things too. The Power+Vol UP was what I tried last time I went through the Unbrick, and it worked, but perhaps it was a coincidence. Please report back if you find that it works for you.

For what it's worth, I tried flashing the boot image on mine again using the one downloaded from the other post, and it worked fine.

Ok making some headway. The Power+Volume up was able to FW and OS Complete it says... However I can not boot. I can enter Droidboot but there is no Fastboot running, even tho it says it is. ADB device is seen.

I have no idea.

Thank you for your time.
[Dell Venue] hharte:
I'm pretty sure what's going on is that the driver loaded on the Fastboot device is the ADB driver. To fix this, when the tablet is in Droidboot:

1. open Device Manager (from Windows command prompt, type devmgmt.msc)

2. Find the device (it probably is under Android Devices.)

3. RIght click on the device, choose "Update Driver" and then "Browse My Computer..." and then "Let me pick from a list of device drivers on my computer."

4. You might have to unclick "Show Compatible Hardware"

5. In the Manufacturer section, pick Google or Intel.

6. Under Model, pick "Android Bootloader Interface."

7. Click Next, and then Ok to Ignore scary warnings.

After you get Fastboot running (fastboot devices should show some output) then you can proceed with the rest of the unbricking process, which is basically running a batch file that re-partitions the device, and then writes each of the partition images one by one. After the reboot you will be back to 4.4.2 stock, and you need to let the OTA happen. There should be one large (~200MB+) OTA.

Then you can continue with rooting...
[Dell Venue] P_Link:
Thanks for all the info. I got the driver loaded with no issues. SO I was able to access Fastboot. Used the files from Dell FTP no go. Just got Intel logo? Any how I read on another post that he had to cobble to together file from the user social-design-concepts post and the files from Dell. That didn't work either but it did bring back the Dell splash screen.
