[Q] Stuck At Boot Animation From Lollipop Downgrade - Galaxy S 5 Q&A, Help & Troubleshooting

Ok so I'd like to put AllianceROM on my international version SM-G900F H3G UK model.
To do so, my plan is to downgrade lollipop to 4.4.2 stock, root with TowelRoot, then install the ROM through Mobile Odin Pro (to preserve the KNOX counter). I've just tried to flash 4.4.2 onto the phone, but I cannot get it to start at all after it's flashed. The phone just hangs on the Three (H3G) boot animation.
I'm hoping that I've just got confused with the Sammobile site and that I've just flashed the wrong 4.4.2 firmware (so far tried flashing ANG2 and ANE2). Something I should have checked earlier but I just thought they were updated versions of the same ROM).
If I can't successfully boot into 4.4.2, I'd like to try flashing lollipop to retrieve some files I forgot to backup (another silly mistake). I'm not sure whether I can take files off it through the ADB sideload or whatever but if I have to lose all my data then I'm not too bothered.
What's the best way to go about my situation?
Any help would be greatly appreciated.

Right, thanks man. After flashing lollipop, I can now boot up and back up stuff. I'll flash 4.2.2 again and factory reset.

[Q] Failed Custom Recovery Update w/ Dandroid 4.4

Phone: Samsung Galaxy S4 ATT I337UCUAMDL
Model Number in settings on 4.4 ROM = GT-I9505G
As the title says, I installed dandroid's newest 4.4 ROM from WICKED v5 4.2.2 and lost root. So I attempted to update my CWM Recovery from Odus 1x to the newest using Odin which failed do to write protected I suppose all though others says that doesnt effect their installs.
Where I'm at:
Cannot boot into recovery, says booting recovery the just reboots and enters Dandroid's ROM w/o root.
I'm now lost and have been reading the forums for hours. Currently downloading STOCK Samsung firmware for my device I337UCUAMDL_I337ATTAMDL_ATT.zip
CASUAL failed.
What do I need to do to get back to WORKING custom recovery w/ rooted dandriod 4.4 kitkat rom. Should I use Odin and flash stock rom then motochopper to root and try to reinstall working CWM recovery?
Please advise best course of action. My phone had been working properly with every ROM I tried before update to 4.4 ROM and attempted CWM recovery update (thinking that would fix my root issue). Thanks all!
If you have a nandroid, and I hope you do, just restore that in your custom recovery. If you don't, then you're going to have to return to stock with odin
Tried motochopper on the phone as it sits and it fails as well.
I have a stock backup but the problem is I no longer have access to any recovery. Guess I'm just gonna have to flash the stock firmware with Odin when its finished downloading and start over.
Just finished Odin flash back to samsung factory firmware. Phone stuck at att world logo on bootup, still can't access recovery. Any ideas?

If you flashed Odin successfully you can get into recovery.
Finally got into recovery it rebooted 3 times but just holding the req. buttons finally got me in.
Back on factory firmware and rooted w/ cwm recovery all back in place properly worrking.
I would like to use the Dandroid 4.4 ROM with this device. When I install am I going to lose root again and if so, how I do I get it back on this device since the model in the settings is going to change from I337 to I9505G after installing this ROM?
Figured it all out last night, re-flashed Dandroid's latest ROM which still caused me to loose root, then flashed SuperSU 1.51 instead of 1.80 and regained root. All is right in the world now.

Hey, if you dont mind me asking where did you get the 1.51 zip to flash? I'm having a similar issues with same ROM where i lost root but have recovery access.
Thanks
Update: Found the file. Flashed it. Root is back. Have you let market update it automatically? If so did you lose root afterwords?

[Q] Att S4 Flashing Issue

I was able to downgrade the phone to NB1 and root it with Towelroot, and used Safestrap in order to get recovery on the device.
After that, I booted into recovery and installed the GPE 5.0.1 ROM.: http://galaxys4root.com/t-mobile-galaxy-s4-roms/gpe-android-5-0-1-lollipop-rom-for-galaxy-s4/
Now the phone will not go past the S4 splash page, reboots and then goes into the stock recovery. Ive tried factory reset, clearing cache and removing the battery.
Any help is appreciated. I bought this phone for my fiance and am wanting to give it to her soon as a present.
Thank you so much in advance.
I think the problem is that you downgraded.

I couldnt install towelroot on the 4.4.4 version it came with since it said device wasnt supported.
I was following these instructions: http://www.droidviews.com/root-att-galaxy-s4-sgh-i337-android-4-4-4-kitkat-firmware-i337ucufnj4/
It states to downgrade, then root, then go back to the 4.4.4. I thought after the steps I took, I could go straight to a custom ROM.
Thanks
I used CF-Auto-Root to root my device. Since towelroot didn't work for me either.
Maybe the rom did not flash right. Try flashing again.

How to roll back to KK

Anyone have a guide on how to roll back to KK. I tried simply flashing the Stock KK rom but it stalls a Samsung logo. I think its due to the Bootloader which I updated to BOC3 when I installed Lollipop. I can't find the old Bootloader.

Before you flash the KK rom, make sure to Wipe data/Factory reset in recovery, then flash the rom using ODIN, once the procedure is complete, return to recovery and wipe data one more time. This should fix the issue and your phone will boot normally.

I had the same after flashing KitKat and then wiping cache. I had to factory reset from recovery for it to boot normally.
Currently lollipop N910c .BOC5
thinking of going back to kit kat.have not tried because it updated to lollipop immediate when purchased.
Anyone who did that.. did you check knox 0x0 ???
Flashing stock firmware through Odin will not trigger Knox 0x1, but keep in mind you'll have to factory reset your device.
Flashed back to KK
I have got a UK N910F and flashed a German ROM this ROM literally ate my battery, after reading this thread I wiped the phone and flashed KK and that worked, prior to this I tried to revert to KK (when I was on 5.0.1) and I could not revert back as I was stuck on boot loop..............Many Thanks

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.

Phone Stuck On Splashscreen

My phone is a verizon gs5 SM-G900V and I tried to root it but something (I honestly have no idea) went wrong and now it is stuck on the splash screen. I have tried everything i thought of, doing a factory reset, clearing the cache partition, I tried reinstalling the stock rom using odin but of course because there was no root and the bootloader is locked, I can't reinstall. I tried applying updates using SD no dice. I am able to access the bootloader and the and the android recovery menu if that will help at all. I don't know every acronym/term because i'm still fairly new to these terms so any help will be greatly appreciated.
I'm guessing you are on lollipop because you say you can't downgrade to KitKat aka stock
so what you should do is go to Sammobile and download either lollipop official firmware bok3 or Pb1.
then install via odin in either ap or pda slot
with the phone in download mode after that wait for the Phone to boot then set it up
then use ok3 root method by Jr Kruse on xda it's a sticky in the s5 verizon forum to get root
