Can you get a menu in response to *#9090# or is the service menu blank? Again, my experience with my phone being corrupted was related to specifically losing the EMEI and baseband through an unlocking attempt via the *#9090# menu route. I'm sorry I'm not a phone internals expert, so I don't want...

I'm a newbie here, so I will help where I can. How did your phone get into the situation of baseband and IMEI unknown, or what happened to put it there? Did you try the *#9090# to unlock your phone like I did, then choosing the first menu option? Did you do anything else to try to solve the...

Problem now considered completely solved. This is what happened, and what I had to do, in case it is of use for other people in the same situation, who followed the Youtube video for unlocking using the *#9090# service menu. I'm running the NE3 stock ROM, BTW. When you follow the video, the...

Here's the latest update. I started with NE3 as my main SW and everything was working when I encountered the *#9090# menu debacle. If I flash MF1 modem, everything works again--EMEI is back, the service menu is back, etc. If I then try flashing the whole NE3 stock ROM on top of that, the...

Halle-gol-dang-lujah! I was trying a bunch of different Odin versions and modem versions, and viola, MF1 modem code and Odin 3.09 appeared to do the trick. I see baseband again! Now, to see if I can flash back NE3 in its entirety and have things work properly! Then, to back up my NV and /efs...

Well, so far I've tried all the suggestions here, and gained more insight in other forums but which do not come with any solution (but may explain the problem). I've tried numerous tools (SA Manager, EFS Professional, and a few online services that purport to perform baseband repair) all to no...

I will try that this evening. From reading many other forums, it appears at this time that somehow the *#9090# menu corrupts the /efs file for the phone, which I'm just learning from what little documentation there is on this file. The /efs is supposedly not touched through ROM update. I plan to...

Well, the ODIN flash went just fine--flashed all the files with a success status. I was chagrined to find, however, that the phone still reports Baseband "Version Unknown" which is indicative of the *#9090# corruption problem. The IMEI is still NULL/NULL and the Service Menu is still blank. It...

Thanks--I'm a bit embarrassed that I found, after following 3 links this morning, your instructions for an NE3 to NE3 load via Odin. I just logged in to say "I got it!" and you'd just posted this... I'll try flashing tonight, and see if it restores the EMEI and baseband that was lost when I went...

One additional question: The firmware download link you gave me has 4 files in it when unzipped: AP_I537UCUCNE3_987011_REV06_user_low_ship_MULTI_CERT.tar.md5 BL_I537UCUCNE3_987011_REV06_user_low_ship_MULTI_CERT.tar.md5 CP_I537UCUCNE3_987011_REV06_user_low_ship_MULTI_CERT.tar.md5...

I'm very curious what the *#9090# command does to soft brick the phone. Did AT&T poison this menu because it was used by consumers to unlock their phones? Someone has to have hacked all the dial code options at some point and reverse assembled the code... I'll read some more and give stuff a...

I am very interested in learning the architecture and ins and outs of the phone and Android for that matter, and toolkits. My current firmware is KOT49h.i537UCUCNE3. Can't tell about Baseband as the phone now says UNKNOWN. I've downloaded the full ROM from your previous linked threads, and...

I'll try the stock ROM reflash, but in other threads on this forum and others, it seems like you also need to flash baseband (modem) as well, and that the version of the modem that works depends on the ROM version installed. I've seen all sorts of mention of ML2 and ML1 baseband, but not the...

Bought an "unlocked" off-contract SGH-i537 that when installing a SIM of an AT&T MVNO, was discovered to be, in fact, still locked. Rather than buying an unlock code, my eager son showed me via Youtube how to use the *#9090# to get into a service menu, and when selecting the first menu option...
