Bootloop even after flashing Stock in ODIN - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
I had not updated the ROM on my phone in quite some time so I recently decided to update everything. I flashed an updated modem thru ODIN and then updated to some Android 5.0.1 and 5.1 roms.
I ended up having some odd reboot issues so I decided I would flash completely stock rom and go from there. I downloaded the most recent stock rom for my phone from SamMobile and flashed it thru ODIN. ODIN says passed and everything looks to have worked.
The problem is my phone will start and boot up to the point where I set up Android (choosing language etc) and then the phone reboots. This happens everytime.
Any advice or suggestions? I thought flashing stock would fix my issue!

UPDATE:
I flashed Stock thru ODIN again and it seems to be working now. I will update the post again if anything changes!

[Q] N900W8 (Rogers) Back to Stock Issue [RESOLVED]

I had an interesting issue I thought I'd share with folks in case they run into it. I have an N900W8 on the Rogers network. I used CF Auto-root to root, installed Philz recovery through Odin (3.07). I backed up the stock OS using Philz, then installed CM11 M5. I played for a couple of days, and then decided I wanted to head back to stock. I'm probably going to sell the phone soon so I wanted to make sure everything was clean. I restored the stock ROM, and when Philz warned that the stock ROM would likely overwrite recovery, I let it. I booted into my previous stock ROM and all was good. I checked software update and it said "your system has been modified". Shoot. I boot back out into download mode and see System and Firmware are set to Custom. All stock 0s everywhere else though, Knox hadn't been tripped. I was about to flash a stock firmware through Odin and I thought.. I wonder if I could use Kies? Sure enough, I fired up Kies 3 and did a Firmware Upgrade and Installation and 10 minutes later I had a stock phone. System and Firmware back to Official Samsung! All I did was boot the phone up in my restored stock ROM, plugged it in, ran Kies 3 and said "Firmware Upgrade and Installation" done.
Hope that might be helpful to someone!

Galaxy Note 3- Updated To Lolipop, Need Help Rooting

Upgraded from Kitkat to Lollipop. Just. Need some help rooting.
So not being very experienced at Rooting/Flashing Roms this may come across strange.
Here is a little background to my problem.
I had a rooted Note 3 running KitKat before I decided to flash to Lolipop. I downloaded the Vodafone (UK) variant of the ROM from Sammobile not thinking anything of it at the time (As I am on Vodafone) I went through the usual procedure of going into download mode running Odin as admin and then connecting my phone, adding the Rom files to Odin and then Flashing. Flashing started fine as it got towards the end it Failed on Hidden(Something).
I panicked didn't know what to do so I unplugged my device and tried to reboot. It didn't. It said something along of the lines as there is a firmware error and got stuck on that screen. Panicked some more, decided I would try to google a fix. Came across one which required me to flash CWM Recovery onto my phone. I thought I would try it, Once it flashed which went fine I was told too try and boot straight into recovery mode once the phone starts and reboot through there. I took out my battery put it back in and then went ahead and tried to boot into recovery which worked. Once on CWM I went to reboot the phone As I hit yes too reboot It took me to another screen where it said I wasn't rooted and if I would like to reroot. I decided to click NO and restart the phone. It got stuck on a boot loop, I did a factory reset and cache wipe and it booted into life. (And working fine so far)
So here is where the problem is.
I am looking to get root back to the device. I think I have a locked boot loader as I installed the Vodafone variant of the 5.0 Rom. Would I be able to Flash the BTU Rom onto my device without bricking it, and after that would I be able to root Via CFAutoRoot which seems to be the easiest way to so. Or could I flash with CFAutoRoot Straight onto this ROM.
Info:
BTU ROM:
Date Country/Carrier Version PDA CSC
2015-07-01 United Kingdom 5.0 N9005XXUGBOF1 N9005BTUGBOD2
ROM I INSTALLED:
Date Country/Carrier Version PDA CSC
2015-06-01 United Kingdom (Vodafone) 5.0 N9005XXUGBOD6 N9005VFGGBOD2
Thanks for any help in advance.
I recommend installing TWRP and flashing supersu.zip from TWRP.
Search "CF Auto Root Note 3 xda" in Google.
That's easy.
Btw i too will recommend using TWRP as recovery.

Problem Solved, Flashed to another 5.0 ROM and then rooted via the normal CF Method. Thanks for the replys.

N9005 stuck in recovery mode

To cut a long story short I was on a S6 port rom and decided to try N5 port. After sometime i did not think it can be my daily driver so decided to go back to my backup. Restored my backup but my screen was always unresponsive, tried many timed but did not work.
So i decided to flash Phronesis rom, but for some reason the phone shuts down everytime i tried to clean the data, or install the new rom. I will have to take out battery again to get back to recovery. Tried multiple times but failed.
Decided to download a stock rom and flash via odin, got BRI-N9005ZSUGOH3-20150904105400 from some thread in google as stock rom and downloaded odin v3.9 and flashed with Md5 in AP. Got the error Volume size is too big 614400<712704.
I remember when i moved from kitkat we had to do something with the pit size but since i was already on lollipop didnt think it was relevant.
Can someone pls advise, what I am doing wrong.
Just to try out i am also downloading the firmware from sammobile to see if there was something wrong in the previous file.
To provide an update, I flashed the stock firmware from sammobile using odin and it passes, however i was stuck at the boot screen for about 20mins after which I gave up. Now flashing stock again using odin and see how it goes this time.
Last update
when the phone did not start up after the next stock flash as well. I went ahead and flashed twrp recovery and was able to boot into recovery after couple of tries then flashed a custom rom again. alls good now.
When flashing back to stock, a full wipe using stock recovery is sometimes required before booting the stock ROM for the first time.

safestrap....unable to mount /system...potential brick??

have rooted s5 on 4.4.4 nk2. Have been trying to install custom roms via safestrap. Apparently i am missing a step. I wipe data, try to install twi5ted Lollipop on custom rom slot....blank screen for over 30 min after reboot, phone gets real hot, take battery out. Try to install on stock rom slot, reboot then get stuck in boot loop and keeps booting into system recovery. I then saw through my hours of searching to format instead of wipe....so i format then try to install, get stuck again, take battery out, get back to safestrap dash now when i try to wipe/format/or even restore my backup it says unable to mount system. When i click reboot system it says no OS installed. After reboot, my custom slot gets erased.
I was about to try an odin flash back to stock but some how was able to get my phone back to a system restore. Why can i not get anything installed? Do i have to have odin to do a custom rom install?????? i know every rom is different but wtf. I have seen multiple videos and threads of people flashing zip via safestrap and rebooting into new rom without flashing kernals via odin or safestrap after rom install.
Also...my phone will not let me download zip files (ex. cm12.1) says unable to create download folder....how close to F'in my phone up am i? I have successfully rooted all phones in the past...s5 is giving me hell!
I just tried installing rom after format, then flash nk2 kernel from odin, still gives boot loop....ive tried everything i have found..never this much problem with custom rom..
When you try to install twisted it needs lollipop firmware which is flashed on odin, and based on your statement it says you're on NK2, a kitkat firmware. Try flashing a stock ncg tar and rerouting, downloading apps, etc. on the phone to see if that works. Also, I noticed you mentioned a cm 12.1 zip not downloading which, while unrelated to your current problem, will cause a bootloop when flashed due to the locked bootloader on the S5, so it isn't a smart idea to even attempt an install.

Click to collapse
thanks, i will try fresh from start ncg. so you have to be on the current kernel that you are flashing a rom for, whether its CM, Twi5ted, Alliance...etc i need to be on rooted 5.0 kernel then flash rom via safestrap?
i was having problems downloading from internet on phone, not downloading rom if thats what you thought i meant. I just tried installing zip for CM 12 via safestrap and got same issue. Phone reboots, goes to black screen and eventually heats up like crazy. .... I just noticed, after my restore ...again... it says safestrap disabled in red on the boot screen, why is that? it says installed and tried reinstalling.
FIXED
So i flashed ncg from odin on the messed up phone and got messed up worse. Ended up getting stuck on first boot image of samsung android s5 boot screen. Finally found original stock firmare file and used odin to complete install stock os and got rid of root. Now back to normal... luckily i figured it out my self! thanks to the 100's who viewed and didnt help and thanks to mrjiggywiggy for giving me some input to help out!

Trying to revert Galaxy S4 I337m (Canadian, Telus) Back to stock rom. Need help!

As the title says.... I'm trying to get everything back to close to stock
I have tried to install the file "I337MVLUGOC4_I337MOYAGOC4_I337MVLUGOC4_HOME.tar.md5" from sammobile, which is suppose to be the stock 5.0.1 Telus rom.
It installed and sorta worked, but at the welcome screen I am greeted with basically all the g-app services and such crashing repeatedly....
I have also tried installing "AOSP-5.1.1-20160410-jflte" with TWRP and it gives me a bootloop....
Does anyone know what I may be doing wrong??
EDIT: So, a second attempt at installing the stock rom worked. But now I'm running in to the no wifi issue.... Can't enable wifi
Flash any stock qb1 Canadian stock rom and perform a factory reset from stock recovery before letting the newly-flashed ROM boot for the first time.
