The image you posted, is that what appears when you turn on the phone or is that what is displayed with phone in download mode?

 

[BigAck]

That's what happen after I rooted it so I try to turn it on and it displays that message

 

[Jfalls63]

Can you get it in download mode?
From off, hold power + home + volume down till it boots then volume up to continue.

If you can get it into download mode, Odin should work unless you have totally trashed the EFS partition or motherboard damaged.

"System software not authorized by Verizon Wireless"...hmmm...Who's phone is it, yours or Big Red's?

 

[Jfalls63]

Verizon loves a locked bootloader. Big Red =Big Brother.

 

[BigAck]

I've been here and tried about all of these

 

[BigAck]

This is a ATT phone I don't know why anything of Verizon is coming on it Verizon never had this phone or even sold it ?????

 

[Jfalls63]

That is recovery mode. Download mode is different.
What is the complete model number?

 

[BigAck]

G750A

Been searching for SM-G750A firmware, 5.1 OH4 and it's like looking for a unicorn. This is all i can find so far.

Another case of AT&T not releasing any.

 

[BigAck]

Ok how do I do it

 

[Jfalls63]

Download mode from phone off.
Press and hold power, the volume down button and home button till phone boots. Release all buttons. You should then press volume up to continue. This should put you in download/Odin mode.

If you can get into download mode you should be able to reflash the firmware.

 

[BigAck]

Yea took it to a cell phone shop they couldn't reflash the software and Samsung themselves said they could do anything period even if I paid get that???

 

[Jfalls63]

So, no download mode?

 

[BigAck]

It won't go up that's it but will go down

 

[BigAck]

Ok I got that now so what do I do now

 

[Jfalls63]

Download Odin 3.10.7 from here and install it on your PC .

Connect phone, in download mode, to PC with Odin open. If you get a blue active com port we are in business.

 

[Jfalls63]

Going offline soon.
If you get a blue active com port, go ahead and download the firmware in the first XDA link and hopefully it will contain a tar file.
In Odin,after you connect phone, select the AP tab then locate the firmware file.
After Odin verifies everything and is ready, select the start button.
If all goes well, phone will reboot when finished and you will see a green box with PASS.

When my VW S4 got buggered. I plugged it into my computer and Verizon Software Assistant was automatically downloaded. 20 minutes later I had a functional device.

 

[BigAck]

I plugged it in and I don't see anything

 

[BigAck]

This is a Att phone bg260

This is a Att phone bg260

Sorry, my bad. If you still need help with Odin let me know.

If it's an AT&T phone, be interested to know how it managed to show a message about unauthorized system software on a Verizon device? Verizon have never sold the Galaxy Mega 2? Did you flash the wrong ROM or something?

If it's an AT&T phone, how did it manage to show a message about unauthorized system software on a Verizon device? Verizon have never sold the Galaxy Mega 2? Did you flash the wrong ROM or something?

Yeah, I knew I wasn't crazy.
