Help IMEI null and Service mode blank

[Papote13]

I just got a Samsung Galaxy Active SGH-I537. Trying to unlock it, I messed up the IMEI and am now getting the IMEI Null error message. I cannot get to the Service Mode, because it is blank. Is there a workaround?

Android version: 4.3
Kernel version: 3.4.02-2244695

Hello and welcome to the forums. Can I ask what u mean unlock to lose the imei only the carrier can unlock.

 

[BRAINZ2013]

Just reflash the stock firmware through Odin

 

[Papote13]

I haven't been able to find the stock firmware for 4.3.

 

[BRAINZ2013]

You didn't make a backup so may I ask who is the carrier

 

[Papote13]

AT&T.

 

[BRAINZ2013]

Try this if they don't match go to the drop down boxes and select the correct one

I have the same thing going on... did you ever get yours fixed? and if not can anyone help me?

 

[BRAINZ2013]

Are you rooted

 

[jacobwilson007]

No... how do I do that? thank for messaging me back.

 

[BRAINZ2013]

Wow if your not rooted shall be easier . check the APN settings and what is the device doing to show a problem

 

[jacobwilson007]

I am rooted now. so now how do I do it?

 

[jacobwilson007]

I run the stock firmware for 4.3 but it always fails....

 

[BRAINZ2013]

Do you have signal on the device if so go to the dialer and put *#06# and press send tell me do u see numbers or the word null . if its numbers Dont put the numbers on here but write the numbers down and match them up on the back of the phone .

 

[jacobwilson007]

no signal on the device, and it is null/null

 

[BRAINZ2013]

Are you rooted

 

[BRAINZ2013]

If you can't flash the stock can you tell me which firmware are you on

 

[jacobwilson007]

4.3_0016 is that the firmware? and I unrooted but it did not work.

 

[jacobwilson007]

Should i go back to being rooted? I feel like I have tried everything

 

[jacobwilson007]

Build number: JSS15J.I537UCUBML2 if that helps

 

[BRAINZ2013]

Keep it rooted as is and try this to get the firmware to upload
This is the stock

I got a pass but still Null/Null and no service mode

 

[BRAINZ2013]

It passed its good cause your not done . now yo need to update the modem for the phone. This needs to be done cause u was updated and now this would be the stock . but you didn't finish did you do a full wipe after getting the Odin to read pass . if not do a complete wipe before you do the modem update . ..remember wipe before you update.

 

[jacobwilson007]

How do you do the modem update? is that stock firmware ? and I wipe, wipe data/factory reset and wipe cache partition. after that I flashed stock still fail with the stock firmware.
