ICS Debug Lock Code Mystery Resolved - Finally

OK...this is probably not a big deal to most of you. But ever since I upgraded my E4GT a few months ago to ICS, I haven't been able to access my DEBUG menu. Which for me is a big deal. I live in that screen!

 

The Debug Screen is where wireless nerds hang out to see what channel they are on, look at their Mac Index, check out their Ec/Io ratio, etc. However, when I upgraded to ICS on my E4GT, it asked for me to enter a lock code. I assumed this was the MSL Code, which all Samsung devices have required to access debug screens in the past...but alas, no.

 

For months I have been searching for a work around, perusing forums, scouring developer comments and I haven't found anything. That is, until today.

 

THE ICS DEBUG LOCK CODE IS: 777468

 

It works on both my Galaxy Nexus and Epic 4G Touch. I went to try it on my EVO LTE, but the debug menu there isn't locked with a code. It may work in other ICS ROMs and devices too. Sound off below if you find it works in other places.

 

Special thanks to BigRushDog on XDA who posted the solution.

 

And for those of you who do not know, to access your Debug screen, go to your phone dialer and enter ##DEBUG# in your keypad. In the GNex, you have to enter *#*#DEBUG#*#*

Robert, will you post some screen caps of the ICS debug screen? I would be very interested to see the fields contained within, as every debug screen/engineering screen/field trial app presents signal diagnostics a bit differently.

Here are a few screen caps - maybe you could walk us through what we should be looking at?

Robert - thanks for finding this! I had all but given up.

 

here is the EVO 4G LTE in the exact same location where I took screenshot of GNEX

can we make any meaningful comparison between the two?

Your signal is amazing. You must be right next to a cell site!

 

I was going to ask if his phones were laying next to an airave. I am in a parking lot with a sprint tower and have a -60 signal.

With a -44 dBm signal, that handset could be practically humping an Airave.

no airave - just an advantage of living "downtown"

 

Was able to get the EVO down to -41 and the GNEX down to -43 for the 1x engineering menu.

Since the GNex has already been posted, I will post the E4GT with ICS for comparison:

Wow... Does your body get warm when you stand by the window? That's some crazy signal. That panel must be right next to you. Are you sure you aren't a NV contractor climbing on the tower rack taking screen shots? :)

He must live on the top floor not far from the panels.

Yup. I have a pretty good view. Location posted here:

 

http://s4gru.com/index.php?/topic/373-my-tower/page__view__findpost__p__10207

 

the panels that are flush with the building are Sprint and clearwire. The panels that are higher are Verizon (I think).

How much of a zoom lens do you have that you can get me a close up of the Clearwire panels? I have something similar to that in Lansing and want to make a comparison.

Anyone know how to map the channel numbers to actual frequencies?

CDMA2000 1900/800 and LTE 800. Playing around with a SDR and want to take a look at the signal.

Going back to the "my signal is stronger than yours" argument...the signal is usually in the -40s. Crazy talk...but that's what happens when the cell site is a block and a half away.

I would get pictures, but I would need to climb up on a mountain or somethig to be able to see the roof of the four-story building where the site sits. Maybe tomorrow, since mountains aren't exactly in short supply around here :)

Having trouble with the difference between RX power (pilot stregenth?) and RSSI.

So in other words the lock code is "sprint" 777468 that is an easier way to remember it :)

 

Never noticed that. Thanks!

    • I am using Starry for my home internet. I hope it doesn't collapse and make me go to cable.
    • Some of the other plans have been throttled, like the ED1500.  Fixes ultimately came, but it took several years iirc.  I moved on to the Sprint Max.  One of my hopes was I would get the billing transition sooner. Nope.  Wonder if they are going after the static IP.  Likely work around is VPN, especially with a smaller more obscure service.  Rumor has been T-Mobile would start transitioning Sprint Billing customers in earnest next quarter  -- wait, isn't that always the promise?
    • I've been using Samsung devices for a couple years and I've never been able to mirror without wifi? I'm not sure what exactly you're talking about.
    • Is there a way to mirror this thing to my smart tv without having to have wifi, the way I've always done with Samsung phones both at home and at work? Samsung phones do it with TCL and other smart TVs as well, not just Samsung TVs.  Samsung has saved me a ton of money over the years in this regard.  If I can't do this then it will absolutely be a deal breaker for me.  I still have the Samsung phone and can use it to mirror but I shouldn't have to default to a three year old phone for this.  
    • So, I've now gone to a legacy Sprint store and talked with various agents on chat, and I keep getting redirected to scripts, with folks throwing solutions at the wall that I know won't work. I have the Sprint Unlimited Plus business plan, which includes 1080p streaming (8 Mbps throttle). But since going TNX I've been throttled to 2.5 Mbps or less for video. Who do I contact and how do I ask them to fix this? 'cuz it sounds like someone has gotten this fixed before?
