[Q] Diagnostics settings

The T-Mobile G2 has *#*#4636#*#* to enter the diagnostics function.
Would there be anyone out there that could give me the best (performance) settting options that I should select with my G2 when in the diagnostic mode? Thanks in advance!

I mostly use WCDMA only. You also can downlaod AnyCut from the market and load the shortcut PHONE INFO and it will do the same thing as dialing those numbers

Also too, why do I use WCDMA only is for it only looks for HSPA+. That way if I'm say in walmart it does not go back and forth on HSPA+ and Edge all the time. If its not 100% HSPA+ than my cell won't connect and waste that little bit of battery roaming

If you're in a city with good HSPA or 3G coverage, use WCDMA preferred. If you're in a city with spotty 3G/HSPA coverage, use GSM auto (PRL). The first will connect to 3G/HSPA if at all possible. The second option needs to reach a higher signal threshold before it switches to 3G/HSPA. I've tested both.

I know this is a newb question but what does it mean when you see all of those numbers and symbols? Is it a number to call or text? I want to know because I say it under the OTA post in order to "Check In" but I have no idea what it means or how to use it.

Its basiclly a code to get into phone information on your cell

You enter it just like a phone call, then it will present the Phone Info menus to you. To checkin, it's the same sort of thing, just dial *#*#2432546#*#*
Hope that helps.

Hidden Service menu Code

I was curious if there was service menu and, found the code for the P920, and I just replaced the 920 with 970 and it worked, code for service menu is 3845#*970#

Wat does it do?

its a service menu for settings and testing purpose for the factory, I was hoping by getting into the service menu I would be able to turn off the LTE radio, but even in the service menu I can`t find anywhere to turn off the LTE radio.

Nuts. That's exactly what I was hoping to find, too. Turn off LTE for extra battery. Should be a no-brainer,but apparently not.

Service Menu > LTE-Only > Modem Settings > RAT Selection > LTE Only
OR
Service Menu > WCDMA-Only > Modem Settings > RAT Selection > etc.

Ah ha! Changing it to WCDMA seems to lock it to just "4g" rather than "4g lte" and it's giving me hspa+ type speeds. Will have to see if battery life improves. Thanks!
So is there a way to make a shortcut or toggle for that?

enable applications from any source in dev options and install the "any cut" apk from the browser
freewarelovers.com/android/download/temp/1281882094_Any_Cut_1.0.apk
create a shortcut to "activity" and then "network mode" - voila! GSM/WCDMA actually turns off the LTE radio :laugh:

Or you could go into build.prop, change ro.radio.network.type to enable then change network mode In the network settings menu

yes this worked perfect, my file I had to change in my phone was ro.radio.networkmod=disabled and mounted as R/w in system folder modified with text editior in Root explorer, ro.radio.networkmod=enable, and save file and exit and rebooted phone. then go in settings and networks ---> connectivity--->mobile networks--->network mode , then you have your network chioices.

Just be careful here. Several of us found that disabling LTE caused a ton of wakelocks and killed the battery. Test it and see.
Hopefully we can get that fixed with a ROM.

I am now convinced (and have told both at&t and lg) that this is due to fast dormancy.
I have not had any success disabling fast dormancy on a stock Rom rooted or not.

There IMEI change function in the service menu.
Is it really works??

I see again another North American Optimus G model that still has the same baseband version as all the rest. Is this implying that all the models should support 700, 1800, 2100 and 2600mhz LTE bands, they just have them disabled in software?

I turned it off for a day just to see and it seemed to get the same or worse battery. I think the longer waits to download things with the screen on longer outweighs the cost of LTE when idle. It did run a little cooler as LTE tends to heat things up. OS might have been a little more responsive too...although that could have just been me thinking I get better battery when using it. Biggest battery saver is Eco-Mode...when it is off this thing drops battery as fast or faster than the Atrix HD I had.
Hopefully FD or whatever is causing the Phone/Android System to use so much battery will be fixed soon and all will be good. Other than that and my back button giving haptic feedback and the OS not responding to it every now and then this phone is nice.
For those interested in getting to the Service Menu quicker I made an app for it- http://forum.xda-developers.com/showthread.php?p=34766577

Does anybody know the difference between the end result of the "factory reset" option in the service menu and going thru the long, convoluted LGNPST method of restoring back to factory settings?

How did you open this on Bell? I can't for the life of me get service to open
- I open dialer
- Dial 3845#*973#
- nothing happens
- I hit green dial key
- A box pops up saying "USSD code running" for a second, then another one that says "Connection problem or invalid MMI code."
Tried eith 970, 971, 973... how are you guys getting this to work?
EDIT: I can't even dial '#06#' and get it to work... does this not work if you are rooted? Did I delete an APK i should not have? What APKs are responsible for loading these menus?
EDIT2: OK - so *#06# pops it up instantly... going to keep experimenting...
EDIT 3: So, it seems to me, that it has to do with timing. If you don't dial the codes fast enough they don't work... very unusual.

[Q] Radio and 3G problem

Hi,
I changed radio on my Galaxy Nexus two weeks ago. I switched to XXLH1 (the last one) and i think that since that time I have problem with my data connection. I cannot get H or 3G in my town. Only E. I didnt have this problem some time ago. Could be the problem in the radio? And if so, Is it good to try to switch to lower version? Thank you!

Dial *#*#4636*#*# then tap on phone information, check if it is set on WCDMA-preferred, not GSM-only.

Where shall I tap? When I tap on the icon of the little telephone to call that code, it says it is not valid.

Install the 'Network' app by Philipp Mangelow. It is a shortcut to that menu.

I have this same problem after upgrading to 4.2.2, selecting wcdma preferred doesn't help...any ideas

N7105 *#9090# default and LTE/4G question

Hi,
Need some assistance regarding a setting for the N7105. If someone could kindly input in their dialer *#9090# and tell me what the default settings are (please do not select anything). Then press back button to cancel.
The default settings are the ones with an asterisk in between two brackets, as seen here (*)
I accidentally selected
[1]DM/DUM over HS-USB
Click to expand...
Click to collapse
when checking out the service mode/diag config using the above dialer code.
On another matter, also in regards to the N7105. Has anyone noticed in Settings>About Device>Status, that their N7105's Mobile network type is consistently LTE:14
Reason being, is that when my phone is displaying that status, my signal bar shows only 1 bar. However, it does sometimes show full bars and the Mobile network type then displays 'UMTS:3'
I am in an area that can receive 4G signals (Sydney, Australia), but I was under the impression that my phone should be idle in UMTS:3 mode for general calls and SMS; and switching to LTE:14 when I activate mobile data and thus use 4G signal.
I am able to make calls/sms and connect to 4G with no problems, however am concerned that since it tends to be in LTE:14 mode the most that it may drain the battery more than if it were in UMTS:3
Thanks in advance.

Bump
Just dialing *#9090# won't change anything, so long as you don't touch any of the options. Simply dial it, look at the defaults, and then press back button to cancel/close page.
Thanks in advance to those who can help.

Mine is on HSDPA:9, i'm using the N7105 also.
Even if its using LTE band, as long as your not downloading data, it wont kill your battery.

Mine is
[2]DM/DUN over HSIC &
[5] DBG MSG ON
GT-N7105T Unbranded (XSA)
