[Q] AT&T Galaxy S4 will not boot into recovery! Help! - Galaxy S 4 Q&A, Help & Troubleshooting

I attempted to flash a new modem into the Omega 7 ROM through Mobile Odin so that I could get working mobile data.
The flash was successful, and the phone rebooted.
However, upon rebooting I was welcomed with the "System software not authorized by AT&T has been found on your phone."
ODIN will not work. The process to reflash fails at "apnhlos" mark. I have no idea what this means.
Can anyone PLEASE help me?
UPDATE: Problem has been fixed. I was able to reboot into Download Mode, plug in to Kies on my PC, and reinstall the official AT&T update. This did unroot my phone, but putting it all back was not a problem.
My advice to those using locked bootloader phones (AT&T and Verizon) is to make sure a project can actually be done on your phone.

Download Kies for your PC, boot into download mode, and reinstall the Official Firmware. It'll unroot your phone and set you back to ground zero, but the phone will safely boot and you can restart from there.

Please search for similar threads. This same issue is being posted over and over and over again. When you were making this post, what "similar threads" or "similar topics" showed up? Did you check them for a solution?
yes sorry i looked at all of them and they all involved well just flashing the stock rom but i cant get my computer to see my gs4 on download mode...i got the drivers and odin installed.
Well, this thread has a couple of ideas...

or maybe here...

You might also want to look at the TWRP thread in the development section.
Try again to get into recovery, the key sequence can be tricky, make sure you are doing it just right. "Doing it just right" has been discussed many times.
Also, look at this thread, maybe it will help...

Yea, I realize that thread is about MF3, but it still has ideas that might help you.
There are also a ton of threads about how to get your PC to recognize ODIN.....search.......good luck.
yeah ive been at it for hours man those links can all access the recovery i cant... i tried everything got the drivers up tried all the odins and its just stuck on "downloading do not turn off target" and my pc doesnt see it...
Odin finally recognized it on the pc in download mode and i was able to flash the stock rom but it seems it wasnts successful...it still just vibrates and vibrates when i press the power...
Try flashing the open recovery.

Take battery out, back in, power+volumedown, download mode, Install Samsung Kies, do Kies update, connect to PC, Tools-> firmware initialization, take battery out and type model/serial Number, wait patiently until it finishes.
Try different USB port or different PC. Use stock USB cable comes with original box.
If Kies screen get stuck at model number section, you did flash MF3 triangle thingy -> unsolveable brick. Have to go thorugh warranty replacement.

[Q] How do I unbrick my galaxy s4???

Ok. So here's what happened. I wanted to root my verizon galaxy s4 and put stock kitkat on it. It was on 4.3. So I rooted it. No problem. Then I tried to put on CWM so I could flash AOPK. But, once I put CWM on, I could not get it into recovery mode. It said that unauthorized software was on my device, not approved by verizon. The only way I could turn on the phone was to put it into download mode and then hit cancel. I wanted to unroot the phone at that point and try again. Also with downgrading it. So I downloaded ODIN and tried to restore my phone to samsung stock 4.2.2. So I tried it, it worked for a while and then ODIN said that it failed. Then when I turned on my phone, it gave me a message saying "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again." So I opened Kies, connected the phone, and tried to do emergency recovery, but it did't recognize my device. So I selected firmware upgrade and instilation. It downloaded and everything but it said "this devices version cannot be updated." So now I have no idea what to do. I can only go into download mode now. Please help me! What should I do?

Not an easy one this one, but can be solved.
First step: get the right firmware from SamMobile. (phone/operator/country).
Uninstall Kies (and USB drivers).
Reinstall Kies.
Obviously, phone removed all the time form PC!
Shut down the phone (it should be fully charged before, using the normal power adaptor).
Get phone to download mode. Still not connected
Connect phone and wait for the drivers to install.
Start Odin and flash the right firmware (watch for the blue button in Odin, it means the phone is connected OK).
IF it does not work, try another USB port (maybe even a different computer).
If it does not work the first time, in spite off all the above steps successful, don't despair. Shut down the phone (keep pressing power button) and restart in download mode. Repeat Odin procedure.

Stuck at bootscreen (no boot loop) and unable to do anything (Galaxy note 4 N910H)

Hi guys,
I own a Galaxy Note 4 (N910H) and have rooted it before without any problem.
Long story short I wanted to install a custom rom and on the instruction says I need to reset my device to factory before I actually install it (because mine is 4.4.4).
I successfully reset it back to factory settings, however when I tried to install the rom an error occured.
When my device restarted it goes into a boot loop.
So I go into the recovery mode and delete the caches and what not (even selecting the reset to factory setting again).
When my device restart it is stuck at the boot sreen (samsung galaxy blablabla) and it DOESNT LOOP, it just stuck there and I am unable to go into recovery mode.
I tried to reflash it using odin (i can access the downloading mode) up to no avail.
My device is detected by odin (com:x) but when I pressed start it stuck at setup connection and after a while I got the Fail message.
Now I am at a loss and have no idea what else to do. Tried kies, doesnt work either.
Kies doesnt even recognize the connection to my phone.
Any help would be appreciated.
NB: I'm a newb at this so please bear with me (and yes I kind of ****ed up)
Thanks

If I'm not mistaken you have Kies installed? If that is the case I would recommend you uninstall it. Then manually download the Samsung USB drivers
http://developer.samsung.com/technical-doc/view.do?v=T000000117
Reboot your PC just to be sure.
Then make sure your device isn't connected to the charger or computer and remove the battery and after 10 seconds reinsert the battery and manually boot into Download Mode (Home + Volume Down while holding the power button.)
Then connect your phone to the your PC and run Odin as Admin and try to flash the firmware.
I would also recommend that the firmware you are flashing is the correct one and is not corrupted.
You can check the firmware from Sammobile and after the download check the MD5Sum and then extract the zip file to get the firmware file.
Good luck and report back.

Just to make sure, should I put the MD5 file to bootloader or AP/PDA?

If you are using Odin version 3.09 or above it's AP, otherwise it's PDA.

Thanks Battlehero! now I finally get my galaxy note back to work again.
Now let's say if I want to Root my device again, is it as simple as installing CWM or TWRP and then install a custom rom?

You`ve to flash the Stock firmware through Odin, then do a Factory Reset.
After successful booting , then you try to root it again.
Got to Sammobile website and download any unbranded Firmware perfect for your device and flash through Odin in Download Mode.
BTW, how you rooted your device ?
And Make sure to check your device`s Battery level before doing any thing.

My S8 (G950U) is stuck in a bootloop and cannot access download mode

Hi i tried rooting my device a few days ago with odin and it failed. When i tried to reboot it got stuck on the sprint logo. I tried reflashing the stock firmware and now when i try to access download mode it says "An error has occurred while updating the device software. Use the emergency recovery function in the smart switch pc software." I figured it would be an easy fix but the smart switch app on my pc said my device is unsupported. Odin still knows when my phone is connected but Im second guessing my abilities to do this on my own so any help would be much appreciated. Thank you.
