I9505 - 4.3 knox after OTA update - Galaxy S 4 Q&A, Help & Troubleshooting

Hi I'm fairly new at this and I've a few questions. I bricked my phone and tried to fix it with kies recovery. Which failed. But obviously from that I got the knox thing. So I fixed it with a PIT file and then I flashed a PDA file via odin from Sam mobile that said I wouldn't be able to downgrade from it, but it works. But when I try run a game or bench mark test my device it will restart and then keep looping on the boot screen. If I take out the battery and then try boot it again it works. I know I've voided my warranty. How would I fix it from restarting? Also would I be able to install a custom rom still or have I blown that by getting the OTA updates?

Boot-loop could also be a faulty battery..? Maybe that causes your device to restart in the first place! You can get a new one from Samsung for free without sending in your phone, they just need serial, IMEI and serial number from battery. I called them 2 days ago to fix this I would do a check just to be sure!
Also see: My phone also hang at the Samsung logo, then rebooted. When I plugged in my charger it suddenly did work. Battery seems to be faulty, waiting for a new one to arrive now!

HELP me rerive my Note

Hey, guys, I got a problem here, it's weird because I wasn't trying to flash when it started, the phone was ok, then froze, I tried to power off, but it didn't work, so I took off the battery. I put it on again, and the screen was freezing on the Samsung Galaxy Note GT-N7000 screen, I decided to flash to a stock rom with Odin, I put in the download mode, Odin recognized the phone but when I started to flash, Odin stuck at the end of the process, I tried in all different usb ports of my laptop, I killed all the Kies processes, but it keeping sticking at the same point of the flashing. Please, somebody give me a hand here.
ps: I tried more than one rom, and it happens the same all the time.
I also uninstalled the usb ports and reinstalled, but nothing changes..
If pc odin get stuck at the factoryfs part and gives a write error then most probably the emmc bug has struck yet another SGN.
Search for forest's guide on uggie's thread about reviving a bricked note. If you are comfertable with loosing about 3gb of you internal sd card then repartitioning is an option. Else if you are on the stock kernel, your binary count is zero and your phone is in warranty, get it to the service center. They should replace the MoBo under warranty.
You can at least mention what rom/kernel were you on and to what are you flashing to....

[Q] Phone rebooting randomly - help needed

Hey everyone,
So, I'm pretty new to Android having had the past two iterations of the Nexus 7 and decided to take the leap from an iPhone (which I had jailbroken) to a Samsung Galaxy S4 GT-I9505 LTE, which I bought unlocked and outright.
I ran stock TouchWiz for a while and then wanted to play, so installed FoxHound 3.2. This worked fine for some time, but then I started getting random reboots which seemed to coincide with listening to music on the device. After a while the reboots suddenly became more regular and it got so I couldn't even open WhatsApp without it either restarting or going into a bootloop. Usually, if it went into a bootloop and I tried starting the phone straight away it would fail, but if I left it off for some time it would start up okay, only to reboot again later if I used it for anything. I also noticed the battery draining quickly.
I tried flashing the device with various other ROMs - PACMan, Google AOKP, etc. - but got the same issue. Many times, the system would crash just when I first started to setup the phone. I finally determined the reason it was crashing at the initial startup was that it was when WiFi was being enabled. So, I ended up following a fruitless several hours of attempting to fix the WiFi using files provided on this page: http://forum.xda-developers.com/showthread.php?t=2192025. I tried XXUDMH8, XXUEMJ7 and XXUEMK8 all to no avail - I installed both the firmware and the WiFi fix files using Odin and thought I had it cracked, only for my phone to eventually reboot again whilst WiFi was not even enabled - it did take a bit longer this time though, admittedly, but it still rebooted and went into a bootloop.
So, I finally followed this page: http://galaxys4root.com/galaxy-s4-tutorials/how-to-unroot-galaxy-s4-and-remove-root-completely/ to completely return my device to stock TouchWiz, but still no joy.
I have tried factory resetting the device and wiping all cache from the stock recovery and from Philz CWM (which I had while using the custom ROMs), but this does nothing.
I tried connecting my device to Kies now that I have the stock TouchWiz ROM back on the device, but it is now rebooting even more frequently and I can't get in long enough to run the emergency firmware recovery. It used to stay up longer (sometimes indefinitely) when connected to the PC via the Samsung factory cable or to a power supply with the Samsung charger, but now it is even rebooting when plugged in.
I am extremely worried that my device that cost me nearly £600 a few months ago is bricked for good. I did (understandably) think that returning it to default would've resolved the issue, but even this has failed.

Hi and thanks for your reply,
I can boot into download mode - one of the only things I can do! - and it says 0x1 under KNOX WARRANTY VOID, so yes it is showing Knox void.
Just in case you need it, the full information shown on the screen in download mode is as follows:
ODIN MODE
PRODUCT NAME: GT-I9505
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
CSB-CONFIG-LSB: 0x30

Hey Repulsa,
Thanks again. Unfortunately, this is what I did. I signed up at samfirmware and downloaded the file: I9505XXUEMK8_I9505BTUEMK5_BTU.zip
The only thing I did different was that I used Odin 3.07 and flashed using the PDA option, but I'm presuming this is the same thing..? After the bootloop, I went into recovery and factory reset, but still the bootloop occurs.
I have since managed to get into my phone after leaving it off for a couple of hours again and looking through the settings it says I have "Samsung" as the secure boot status and "Official" as the device status. The build number is showing up as JSS15J.I9505XXUEMK8 on Android 4.3.
Should I try anything else that you can think of?
Thanks again for the reply.

Yes, I'm afraid it does, and I have already done the wipe cache and factory reset, but no joy. I did it again anyway and on reboot it went back into the bootloop again, I'm afraid..

Ah FFS. My battery serial does start with BD and I was wondering if it was a battery issue, but didn't want to replace it if the fault was wider spread. I guess I may have to try this then..
I'm just flashing to MJ7 right now, but if it reboots again I will see about a new battery from where I bought it on Monday
And, as I forgot to say in the last post: thanks for your reply. If this fixes it, much kudos, my friend..
Yep. The flashing of MJ7 did not work. Maybe my battery is a dud as it went straight back into a bootloop at the Samsung logo.
Carphone Warehouse visit on Monday methinks..

you can get passed the samsung logo if you boot while your charger is connected to the phone, the battery might swell as well or is already bigger then it originally was
My phone has been randomly shutting down over the past couple of days and the only way I can get it to boot is to connect a charger/cable to pc. I've tried different ROMs and returning to stock. No joy.
I guess my battery could well be the problem

My phone has randomly started shutting down over the past couple of days and the only way I can get it to boot is to connect charger/cable to pc. When it dies, it also loses all of my wifi passwords. It's a bit of a head scratcher. Any help appreciated
Definately the battery, dude
I was experiencing the same problems, and I observed that the battery swollen. So I replaced it and now the phone is functioning properly. Do not wait for the battery to modify its volume because you are risking to put pressure on the display and crack it. Beware.
Was, indeed, the battery
Hey everyone,
Just to let you know that I went back to Phones4u with the receipt from September (when I bought the new phone) and they filled out a form to request a new battery from Samsung and replaced mine their and then in the shop with a new battery from another Samsung Galaxy S4.
My old battery did, indeed, have a serial number that started with BD and the new one starts with AA so hopefully I am now sorted.
Massive thanks to everyone who replied and hopefully this thread will save someone else the time and lost data that flashing ROMs can incur.
Cheers,
A very happy Steve :laugh:

Note 4 Stuck in Boot Loop - Help - Recovery not working - Flash stock Rom not working

Note 4 Stuck in Boot Loop - Help
I have a Note 4 SM-N910F, never been rooted, stock rom upgraded to 5.1.1 back in October, working fine until yesterday when it got stuck in a Boot loop.
Not sure what caused it but before it got stuck I was messing around with Google Photos which was running a bit slow.
Also I put it on the Qi Charger just before the loop started. It has an aftermarket Fone charger stuck to the battery. I’ve had this and the Qi Charger for 6mths with no problems before now.
It gets to the Samsung page waits a couple of seconds then boots again.
Here’s what I’ve tried - unsuccessfully - to fix the boot loop:
1: recovery mode.
I can get the little recovery text to appear in the top left but after a few seconds it boots again.
2: volume down, home
This gets me to the screen with up/down for continue/cancel.
This is the _only_ screen I can get to stay up without rebooting. It sits there waiting for input.
- Cancel, causes restart, of course, but back into the bootloop
3: Mashing on power button. Banging it, wiggling it, blowing on it.
I read somewhere this could cause a boot loop, but I doubt it is my case because
a. I’ve never had problems with the power button before
b: When I take out the battery and put it back in, it does NOT turn on. If I do the same holding the power button, it powers into the boot loop. So if the button were jammed on I would expect it to never remain off with the battery in.
3: flashing stock rom
I’m not 100% sure what build I had before. I know it was stock 5.1.1 OTA, and I’m pretty sure it was unlocked (my wife bought the phone and i inserted my old sim, but she may have bought it from my carrier and can’t remember)
So anyway I tried all three versions of TPH (unlocked) 5.1.1 from Sammobile.
Installed Odin 3.10.7 and flashed them.
It reboots to recovery but immediately boot loops again.
I doubt its to do with the version of the rom anyway since the symptoms are identical after flashing. Only now the boot loop always shows the little ‘recovery booting...’ text in the top left.
Here’s what I have NOT tried but am thinking about:
A: Re-partition option in Odin
B: Nand Erase All option in Odin
C: Buying a new battery.
On A/B: as far as I can tell what I have done so far should have left the data intact. I’m prepared to wipe all my data if it fixes my phone (no lectures about backups please!) and I’m tempted to do one of these on the off chance that the problem is caused by data or the “disk" problems.
But I don’t want to brick it. Can someone recommend how likely these are to help
And what they actually do?
(Please refrain from responses I see elsewhere like “this will brick your phone if you don’t know what you’re doing”. I don’t know what I’m doing, thats why I’m asking - just the facts please)
On C: the battery seems ok in that the power is solid even after not being plugged in for a long time, but since it was on the Qi Charger with that aftermarket thing stuck to it when it happened, I’m suspicious. Can any one say if this is a likely cause?
If so, it might be worth waiting till I get a new batter before doing A or B (can I wait days for Amazon!?)
[UPDATE] Got a new (genuine) battery at a local electronics store. No dice. Same problem, so it's not the battery. Shall I go ahead and re-partition.
[UPDATE] Got a PIT file from another forum, and flashed again with re-partition checked and PIT loaded. same results.
Is Nand-rease worth trying?
The phone is still under warranty so maybe I can return it.
But in that case I want to erase what's on it first.
thanks for any help

I don't think that the Samsung service center will accept cuz u have unofficiall custom
Simple Go to ur any nearby SOFTWARE ENGINEER may be he will help u out
Even I had the same problem with my NOTE 4 EDGE
Try downloading and flashing any "COJ5" build of 5.1.1 from sammobile. Samsung has recently issued a new update "COJ5" it basically locks down the bootloader and will not allow the device to run any previous builds.....Maybe your phone updated to COJ5 in the background and then it started messing around because the phone is rooted. Flashing "COJ5" will lock your bootloader and you will not be able to flash 4.4.4 or 5.0.2 but there is nothing to lose when your phone is already pretty much dead?.....ORRR if this is not a software issue then it could be related to hardware maybe the memory of your phone is done. I am not an expert on this but this is just an advice.....i have told you what will happen if u flash coj5 build now its up to you to decide. I would suggest you wait and wait if you are lucky to get a response from an expert and do what they say .......if not then give this a try!
**EDIT** another idea....First flash a custom recovery such as TWRP....see if it lets you boot into recovery and if it does then perform all sorts of formats.....and factory resets in there see if it works....if its still rebooting after format then flash the coj5 build of 5.1.1....note that you "MUST" format it with TWRP first and then check if its working because once you have coj5...it might not let you flash custom recoveries.

You can flash TWRP through ODIN while on COJ5 bootloader. It's locked but you still can flash recoveries and kernel and 5.1.1 ROMS
I am very interested in this thread. I have the EXACT same problem as you have after installing SimplRom, which was a ROM prior to COJ5. It could indeed be that our bootloaders are locked now?
I am using the N910F and just like you, installing any ROM/Custom Recovery/Bootloader/Kernel doesn't help. Perhaps installing a COJ5 ROM might help. I will give that a try, but I've recently used Kies to install the latest official firmware, but it didn't fix the issue.
I will report back here and we'll work on this together to make our phones work again!

Thanks to you and dork97 for the ideas. First some notes:
- I have never flashed a custom ROM, nor ROOTed this Note 4. The recent upgrade to 5.1.1 was official.
the first upgrade to 5.0.1 was automatic and after that I turned off automatic upgrades and upgraded to 5.1.1. manually. So I dont think it was an upgrade that caused it and it certainly was NOT a custom ROM or ROOT. I was doing nothing at all when the boot loop started.
- I'm not sure what ROM I had, but when I went looking for the available Portugal unlocked ROM, which _should_ be what I had, the latest were CJ03 (3, not 5) and before that CH03, CI03. Presumably I had one of those (my last update was October, so probably CH03).
I have tried all 3 of these, but the symptoms are the same.
I'm tempted to try the TWRP option - but would like some more details on what is and what it does, or what problem I might have that it would fix.
However I am probably still in time for a warranty repair - especially since I didnt actually do anything for this to happen. I would like to avoid losing that chance.
If I do take it in for warranty, I'd like to wipe the memory first though. How can I do that?
Finally can anyone actually tell me if the NAND ERASE is likely to help? How does flashing TWRP compare?
I get the feeling in fact, that I have a hardware problem. Especially given there were not software system changes around the time it happened, and given that it loops while trying to boot into recovery mode. In fact the only mode that doesnt constantly cycle is download mode. (Even holding the power button in dl mode does nothing which makes me suspect that, but pulling the battery out and replacing it leaves it off until I press the power button so perhaps not)
Thanks for the replies so far. Any more ideas, details?

I have the exact same as you. I did install a custom recovery (multiple) and still get the bootloop. From my tries yesterday, I indeed also suspect it may be a hardware issue. Perhaps to do with the battery/charging port. When I have my device unplugged and try to start in recovery/normalboot, it does not have a bootloop but simply turns off (and then doesn't respond until I pull the battery out). I think a NAND erase wouldn't do anything as I've personally tried that already.
Have you prior (upto a week) before you got the issues had your phone in a moist environment (bathroom while showering for example). I got my problems a week after I accidentally left my phone in the bathroom and installed custom ROM (which was done earlier and had no issues).
I've read online that it may have caused oxidation on the inside and may need some cleaning/drying with alcohol.
I still hold hope that we just have a software issue as download mode is working fine (apart from the Power off not working unless we pull out the battery).
Anybody have any experience with oxidation on their phone? Perhaps have had a similar bootloop due to hardware failure?

Since you can get into download mode I'd flash firmware through ODIN again after verifying it's correct.
I'm seeing off the sammobile site for the 910F not all are the COJ5 locked bootloader.
Since you did update in Oct you may be on the COJ3. I'd try one of those and see if it works.
If it doesn't work and stops on the sboot.bin file then you have the COJ5

i am sorry i don't know any way to remove personal data other than doing it via recovery. There is an option of "nand erase" in odin it is used while flashing firmware and it wipes everything on the phone but i have never used it (and also don't know whether it can help you or not) ... Senior members kindly help us with this.
Any update to your situation?
very interested as I am in the same situation as you are. Download mode works, recovery+normal boot not. No matter what ROMs/recoveries I install
Same issue I think
I am also in the same situation, although I can enter the recovery mode - home power and volume up - I have tried the wipe cache and then factory wipe to no avail - I have also entered download mode and flashed the stock recovery and even though Odin says pass, it is still in a boot loop. Also when I go to the download screen it has a line saying knox warranty void 0x1(4) does this mean I have voided the warranty even though I only used Odin to flash stock recovery?
Did anyone found a solution
Did anyone ever found a solution to this problem I'm having the exact same issue on a note 4 smn910a
I have a slightly different issue with my Note 4 SM-N910G, wherein am not able to start the phone at all, it is completely dead, if i put the cell phone on charge then also there is no LED on the top but if i connect the device to the PC it does make the connected sound on the PC but Odin is still not able to recognize the device neither kies. I tried draining the power by removing the battery, connected the device to PC without battery and then inserting it but the same problem. Please suggest me any resolution for this dead body am carrying from past few weeks.
hi Op,
did you find any solution for this issue?
Hello all. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.

Note 4 G910F Snapdragon weird issues / flashing and usage

Hey guys!
I'm posting here in hopes someone could help me with my issues.
First and foremost, the phone is behaving erratically since the latest official update.
Phone was unrooted and untouched, only by official OTA updates.
-After the latest official OTA update, the phone hangs, reboots, sometimes when I try to unlock my phone it just doesn't respond to commands, sometimes it doesn't get past the first screen that shows when you power up the phone.
-I tried flashing a custom ROM for the first time and I got "mmc write error". I couldn't flash any other ROM, neither using Odin or by trying to restore the phone through Kies. The phone encountered the MMC write error with anything I tried to flash (this was happening at system img).
-I then tried the "fix mmc write error" guide here on XDA which promised to fix the error, but it didn't work. I followed all the steps and even used the repartition option with the provided .PIT file.
-Then I flashed the Philz touch recovery, rooted, and I formatted every partition besides the most important ones like EFS.
-Now I was able to restore the phone with Kies and afterwards I was able to flash any custom ROM (tried a bunch and the phone behaves bad (the same) on any ROM. Some ROMs don't even boot).
-I don't remember where, but I've read that the latest official update for the N910F screws something in the bootloader, and makes the phone behave eratically. Is there any known fix for this? Is there any bootloader I can flash so that the phone will work fine as before? And if so, what version should I use?
-I've read around and it was suggested that the battery might be causing these issues. So I went out and bought a new genuine note 4 battery and replaced it.. Sadly it didn't fix the issue.
I'm now on the custom RamRom with their custom RamKernel (for the 910F variant) and sometimes it works perfectly, other times it just hangs and is unresponsive until I pull the battery out and do a fresh boot.
I would of returned the phone in a heartbeat, but it's out of warranty, and it's such a shame it worked perfectly fine before the latest update. I feel it's Samsung's fault for the bad behavior of the phone but there's no way I can hold them responsible now, with the phone out of warranty and with the knox counter tripped.
Sorry for posting this big block of text and thanks to anyone reading it / shedding some light on my problems
Thanks!
Bro something similar happened to me as well .. even I did purchase new battery as everyone and also repair service guy said it's due to battery but that didn't solved the issue ..
Kindly check this xda post by me , it may help you.

Your facing emmc failure *your internal storage is corrupted* After a certain amount of read/writes, it ends up crapping out.
short note you may find a workground for this problem but at the end changing the motherboard is the only solution for you..

While this might seem plausible, it is very hard for me to accept, because prior to having these problems, I never flashed anything to the phone, apart from official OTA updates. I find it really hard to accept that the part of the MMC - internal memory which is assigned to the operating system has been written so many times as to cause failure..

Believe me i use to feel the same but now i am all careful not to loose my warranty i am on stock rom too knox is not triggered.. Emmc failure is a time bomb lots of people are having the same problem it's a hardware defect doesn't matter if you're custom rom or stock rom.. my phone is almost new 8 month old and am having a problems with phone already. phone shutting down at 20% and going into bootloop i have to charge the phone so it could boot up normally now i found many users are facing the issues..
The weird part is only the snapdragon variants are facing emmc failure while exynos don't

Thanks for your help, Amar! I've put some thought into it and I'm considering looking for a new motherboard. Maybe even an exynos one if it fits.
I'm very puzzled as I own other phones too and it's the first time something like this is happening.
Thanks again!

SM-G935F issues after update to 7.0

Hey guys I'm newly registered to the forum but have always scrolled through various posts to get answers until this bizarre issue.
I have an SM-G935F and as per the title it randomly shuts off and becomes completely unresponsive. If I connect it to a charger it doesn't recognize it and I've tried the pressing the volume down and power button to simulate battery pull, which doesn't work and I can't get into recovery mode or download mode. If I leave the phone overnight and plug it in to charge the next day, it recognizes the charger, I charge it up to 100% and it's fine again and I can get roughly 20 minutes use out of it before the cycle repeats.
The OTA update kept failing so I updated my phone via Odin with the firmware from sammobile (just the BL and AP files), as I've done several times in the past when OTAs have randomly failed. After flashing with odin, I always enter download mode to check it's all official and it now says warranty void: 1 (0x0500) which I know is KNOX being tripped, but I've never rooted my phone. The binary and system status are both official but I'm baffled as to why KNOX has been tripped.
If anyone has any ideas as to what to do to make my phone stop crashing and turning off, (I know you can't reset the KNOX counter so I'm out of luck there, as frustrating as it is) I'd fully appreciate your help. Using a Samsung J3 after my S7 edge is a painful experience
Thanks in advance guys.

That's very unusual to trip knox via Odin, was second hand phone?
Maybe try flashing 6.0.1 firmware and hold off updating until 7.0 is sorted.
It was an upgrade on my contract in October so it was brand new.
I'll try to flash 6.0.1 again and see if I have any more luck with it.
I'm tempted to go back to the store and ask for a replacement but I know they'll question the warranty void counter. I'm just so confused as to why it's tripped it.

Perhaps is a bad flash reverting back to MM should fix issue but certainly not knox counter.
I'm also awaiting long overdue nougat update and was going to flash via Odin until I read your post. Slightly nerves now wonder if anyone else has had the same issue of tripping knox.
I've just updated via odin and no knox trip, void counter remains the same.
I reverted back to 6.0.1 and the issue still happened which is making me wonder whether or not it's a hardware issue.
I'm going to download a ROM (probably superman rom) and try flashing that through TWRP and see if that fixes it. I won't be able to do it until I'm home tonight but I will get back and update you on how I get on.
I'm glad you successfully flashed 7.0 without any issues, hopefully I'm the only one who has this problem.

If the problem occurs on the official ROM, flashing custom one won't help at all. I would recommend you flashing again nougat after wiping all data, system, cache via recovery mode

I'll give this a go tonight and see how I get on.
I find it very odd that both 7.0 and 6.0.1 gave the same restarting issues which is why I'm worried it's a hardware issue and not software.
I do have the TWRP file so could flash that, do a dalvik and normal cache wipe too after installing nougat again.

So I installed 7.0 again and it is still crashing and becoming a completely unresponsive phone with a black screen. Again, left it over night and plugged in this morning to charge and it's on again. I have absolutely no idea what to do to fix this issue.

Hey buddy it might be because of wrong varient rom flashed so knox may be tripped
Try downlaoding and flashing the original variant and original country rom from samfirmware.com and it might actually do the trick
As for your battery problems, it might be a charger or port problem based on maybe if the cord might be streched more than required accidently or maybe the charger has encountered a fault or power surge so its circuit might have failed to safeguard your phone from over surge of current and over heating.....try using original but substitute charger of someone else

Hey mate. Unfortunately I've definitely got the right variants for UK Vodafone, I did use sammobile so I'll give samfirmware a go and see if that fixes it.
The charging thing is an odd one, once the phone boots and is used for 10 or so minutes it will crash, the screen will go black and no matter what trying to reboot, go into recovery or download mode, nothing responds. The only way I've found to get it responding again is if I leave it overnight and plug it in to charge the next day, then it'll start charging and I've tried both mine and my partners cables in both plugs.
I might just take it back to carphone warehouse and tell them whatever has happened during the update has tripped knox and completely ruined my phone, it's only 3 months old to ? they must have a way of finding out if I'd tried to root because if they did, they'd see I've never tried it.

Return it. If Stock ROM doesn't fix a problem, the phone is good night

Since installing Superstock Rom, the phone has, so far, been completely crash free and no random reboots when trying to do something simple like uninstall an app. Fingers crossed it stays this way!
