So my G925F got bricked recently by updating the phone to 5.1.1 UK BTU firmware (G925FXXU2BOFJ) and the phone would not boot up. It was stuck on the boot logo. I did hours of research and finally managed to get it working by flashing Unibase Kernel.
Now the problem I am facing is that I want the phone back to 100% stock. Even unrooting the phone won't work because Unibase will reinstall SuperUser during restart. If I reinstall 5.1.1 using Odin it will hang on boot logo until I flash it with a custom Kernel, in my case Unibase did the trick.
Ive also flashed the phone using Samsung SmartSwitch with original firmware it still fails to boot until its flashed thereafter with a custom Kernel (UniBase)
Ive also tried the solution of removing hidden.img from firmware then repacking and flashing it, still seems to be the same problem (hanging on boot logo) Ive also tried to hard reset phone after flashing and yet its still faces the same problem. Is there a stock Kernel or any other solution anyone may know?
All help is appreciated and I will be happy to try any solution or method posted. Cheers
flash stock firmware with odin but uncheck auto-reboot. Once its done boot into recovery, clear cache, factory reset and it should boot
Please check and try this

Mine didn't boot and KNOX was touched and after i flashed a stock ROM via ODIN it was all ok. I used but a ROM from https://www.samdownloads.de/firmwares/alle-firmwares/#

Thanks guys, Ive tried both of your solutions, unfortunately the problem still exists. The phone will hang on
"Powered by Android" boot logo until I flash it with a custom Kernel. Weird problem
Ive checked, its definitely the boot.img causing the problem. Unibase flashes modified boot.img which turns the phone on

Out of interest, why do you need to return it to 100% stock?

Hi I have done something silly in the flashing process and now the phone wont get past the Samsung logo and is stuck in boot. I can get to Recovery and Download mode. Have tried flashing stock ROM twice but still the same result.
Here is what happened
1) Flashed Stock 4.1.2 XELLA ROM - Through ODIN - was successful, used it for 2 days
2) Due to battery drain issues did a Factory reset and Reflashed XELL4 Stock ROM through ODIN
3) Phone got stuck in boot screen on Samsung logo so reflashed the XELLA firmware again but its still Stuck
Each time the ODIN gave a successful flash but the phone does not get past the Samsung Logo
Dont know what to do it looks like something got screwed up perhaps due to the new bootloader in XELLA which has messed up the process???:crying:
Device I9300, UK version from Carphone warehouse
Will it help if I try the emergency firmware recovery on should i send the device to Samsung as its stll covered under warranty (Have only flashed Stock RoM and not rooted)

Not an expert, but would a full root be able to fix this?

Yup tried that before posting no luck with it!
Sent from replacement device grrrr using xda app-developers app
So I've got this issue I never had before.
It started happening after I screwed something up with the EFS I think.
I was flashing some custom roms after the 4.3 official update and then tried to go back to 4.1 official.
Had the no network problem, but fixed it flashing the vodafone stock 4.3 official again.
Reading all the stuff about EFS confused me, and I deleted the EFS folder and copied an old backup (or so I think, because I'm not sure. I had a EFS backup on my sdcard and extsd I think).
I no longer have the no network issue, but everytime I flash a stock rom through Odin the phone gets stuck at the samsung logo, so I have to root the phone and install TWRP using Odin and then wipe. I know this way fixes this, but what I'm looking for is to fixed the problem completely so I don't have to install a custom recovery or root after using Odin to go back to official samsung rom.
Any ideas?
What should I do?
Maybe the phone gets stuck at the samsung logo because all of this EFS thing, but, like I said, I no longer have the no network issue.
All I want is for the phone to boot normally into the setup after flashing a samsung rom using Odin.
It just gets stuck every single time since I had this problem with the EFS, when before this never happened.
try to install the rom in recovery mode

I had this problem before (flash 4.1.2 in current 4.2.2 by odin), here's my solution.
Maybe you can install your ROM in recovery mode. (CWM based)
Remember to wipe completely before installing

I can flash custom roms through TWRP, but what I'm looking for is to be able to do so again through Odin without ending up stuck at boot always and having to wipe through TWRP to be able to boot properly.
Any ideas?
I'm sure there must be a fix so I don't get stuck at the boot screen after flashing a samsung rom with Odin.
I know the trick wipe factory reset but what I really want is to simply avoid getting stuck at the boot screen after flashing a samsung rom with Odin.

Factory reset is also available in default recovery as well, then what is the issue? Flash then boot to recovery do factory reset.

Thanks.
I'm just trying to find out why my SGS3 now gets stuck at boot when before it never happened.
I'm hoping there's a way to fix it and go back to before, when it never got stuck at boot. There should be a way I guess.
Hi guys, my mothers SGS3 is stuck on bootloop (well just freezes on samsung logo), it was on stock firmware when the problem first occured, i've tried flashing cwm via odin, wiping absolutely everything and then reflashing stock firmware, but problem persisted, i've tried rooting, flashing cwm, and then installing cyanogenmod to no avail.
does anybody have any other ideas that i could try.
Thanks in advance guys.

You flashed stock firmware with Odin, was the flash successful ?
If you need to use recovery, flash TWRP or Philz, CWM is not updated anymore
Try flashing one of the firmwares in this thread.
yeah as far as odin was concerned the flash was successful and set the phone to reboot, but it still just hung at the samsung logo, and right ok im a bit out dated using cwm then it's been a while :Lthanks for the links i'll give it another crack now
thanks again

i've tried flashing CM and MIUI using the two recoveries you linked, still no joy. The download links for the firmware doesn't work but i found an equivalent that also has bootloader, csc files etc and still no joy, odin does it's business and says in green pass at the end of it all but it still hangs on the samsung logo, even when i installed miui, it would install all as planned, but then on the reboot it just hangs at the MIUI logo.
i'm lost completely i've never been defeated by a phone :L

Why don't or can't you flash any rom specific to your variant in TWRP that you now have?

sometimes it hangs at samsung logo and sometimes it restarts.
Hi,
I have the 925f. I was in a custom rom but had some issues in my phone (7.0 A8 port), so I decided to flash back to stock through ODIN. After flashing G925FXXU5ERA4 it was stuck almost 30 min in samsung logo. Then I went back to DL mode and tried again with the same result. I also tried flashing G925FXXU5EQFC but again it was stuck. I did this several times.
Am I lacking something? Any help will be appreciated.

If it's stuck in Samsung logo just leave it longer, the first boot can take quite a while
Thanks callumbr1!
It was almost an hour and it didn't passed the logo (I tried two stock roms through ODIN). I solved it by flashing twrp wiping system and a rom through a zip file.
