[Bad/Failed Root?] Samsung Note4 Keeps Auto-Restarting - (Model: SM-N910G) - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi Guys,
Recently got the a Note4 after being an S4 fan for 2 years. Tried to go ahead and root my device and i presume failed miserably. I don't think i did enough background research like i did before when rooting my S4.
Model: SM-N910G
Android V: 5.11
So,
I followed this to root my NOTE4: http://forum.xda-developers.com/note-4/orig-development/sm-n910-cf-auto-root-t2897428
Then my phone didn't pick up any signal and kept restarting every 2 mins once the device was turned on. So i looked around some more threads and saw a post that i should download and boot this:
http://forum.xda-developers.com/showpost.php?p=62241991&postcount=56
I still have no Mobile data signal and my phone keeps restarting!
Any guidance how to get it back to normal? I don't even care about having my phone rooted anymore - Or am i completely stuffed?
Many thanks!

download stock firmware from sammobile and flash with odin.

You've been doing things wrongly.
Firstly, the CF autoroot for N910G currently only supports up to android 5.0.1.
Secondly, you should not ever install kernel that is not for your specific phone model. Sprint Note 4 =/= International Note 4 Snapdragon (N910G)
To restore back to normal, download official firmware for your phone (N910G). And then flash it using Odin 3.10
Edit: Download official stock firmware from either Sammobile or Samsung-updates. Or u can use the firmware downloader created by fellow XDA member. Be sure to download the correct firmware version/carrier

Thanks guys. Problem solved!

[Q] Soft Bricked n900 HK Version

Hi, i was using a Note 3 N900 which was TGY (HK Version i believe), its running N900ZSUCML1 firmware. By about an hour ago i got bored and decided to play with it a little, so i started rooting it using CF Auto Root, it worked and SuperSU was installed. I got a little cocky and tried to install a KitKat Stock firmware using Odin v1.85 but the firmware i was trying to flash was the Indonesian (XSE) Version. By the time i realised, Kies could not recognise my phone, i tried re flashing back to the ML1 firmware with Odin but it says fail, i think i tripped my knox warranty but i coudnt care less about it now i dont have a phone.
I looked up guides on how to recover from soft bricks, but those are only available for either SM9005 or VZW Note 3's, is there any way for the inlt note 3 to get a piece too??
Please Please Please any help would have my undying thanks! :'(

[Q] Downgrading Galaxy S5 (Sm-G900H) from Lollipop(5.0) to KitKat4.4.x

Hello guys!
Recently I downloaded the Lollipop firmware from SamMobile and ungraded my Galaxy S5(G900H) to Lollipop but to my utter disappointment the new Android is gross for me.
So I just want to go back to KitKAt and my serious question that would it be just fine if I download the StockROM(4.4.x) from SamMobile and flash it through odin?
Will I not lose my Service Signals?
Would I need any particular modem after the downgrade?
My phone is not rooted,
Thanks....
You should be all right as long as you're getting the right version for the right device based on the right carrier. I've found that Kies has made it possible to unbork my past devices, but right now I haven't attempted to downgrade my phone from lollipop to Kitkat using it.

[NEWBIE] Need help to root my Note 4 SM-N910G

So I have a Note 4 SM-N910G Variant Currently running 5.1.1 Lollipop and I'm looking forward to root it since my warranty is over. (Snapdragon) I want to flash dr.ketan's rom ( http://forum.xda-developers.com/note-4/snapdragon-dev/n910g-dr-ketan-custom-rom-t2928568 ) but obviously I need to root my phone first.
I have researched through many youtube videos and website for Rooting and to my understanding, I need to download a kernel and flash a recovery called TWRP, flash SuperSU and then flash the ROM itself.
But so far, All I could find were kernels for other variants except N910G, some of them said that I can use the kernel for N910F ( http://forum.xda-developers.com/note-4/orig-development/tw-kernel-emotroid-team-t2990557 )
Can someone help me? And correct me if my understanding of the root procedure is wrong.
Really really really appreciated If you can help me
I tried to flash a kernal for SM-N910F 5.1.1 on my SM-N910G and it stopped my phone from booting (soft brick, got stuck on the first Samsung splash screen). I'm fairly certain that I did it correctly but I am new to Android so it might have been my mistake. I did get my phone working again by downloading the vanilla 5.1.1 SM-N910G firmware using SamFirm and installing it via Odin.
EDIT: I have successfully rooted my device using Noname Kernal http://forum.xda-developers.com/showpost.php?p=63217526

Help with a troubled Tab 4 7.0! (Downgrade & QA)

Hi community I just need help to figure out what to do with my Tab 4 7.0 the history begins this way:
I get this Tablet already used not brand new it looked to have Android Lollipop 5.1.1 when I got it and didn't appear suspicious and lend it to one of my kids, the problem begins after some time the Tablet didn't connect to the Play Store anymore proly because my kids was trying to root it via KingoRoot or other apps to mess with some games, so after that I decided to solve the problem doing a Hard Reset but it didn't work, the tablet still can't connect to the PlayStore via RH-01 error message.
So I decided to flash it with the official stockl rom from Samsung, my BIG surprise is that this Tablet never get Lollipop 5.1.1 it didn't ever get Lollipop at all accordingly to this thread: https://forum.xda-developers.com/tab-4/general/links-galaxy-tab-4-official-lollipop-5-t3102844
Because my tablet is the SM-T230NU (the model accordingly to the box is SM-T230NYKAXAR) model and that model never gets LL, so I figure it out this was a modified rom? Even in the Info about the device over settings it says the model of the device i "Nexus 5" instead of Tab 4 or whatever Samsung call this device but not Nexus 5 that is a phone from LG.
So I stopped here, because I've heard it can be dangerous to Downgrade Android versions? If not what should I do? Use Odin3 and flash the rom mentioned in this thread: https://forum.xda-developers.com/tab-4/general/links-stock-galaxy-tab-4-firmware-t3013128
For the T230NU USA variant? Hope u can advice me about what to do and give some tips because this will be my first flash on a device.
Thanks in advance! :laugh::good:
They probably flashed a custom rom with broken GAPPS, just restore with Odin and the official rom.

Click to expand...
Click to collapse
By restore u mean flash it with some of the roms provided in this link: https://forum.xda-developers.com/tab...mware-t3013128
So there's no problem if I have 5.1.1 right now and get down to 4.2 as is the official one?
