I stupidly clicked USA Band on the first day I got my phone. Signal disappeared.
Was able to get it working again by selecting band 38 (tried each one).
Is there any long term effect with this? Can it be reset?

Hello, I'm in singapore and when i keyed in *#*#4636#*#* , went into phone info and then clicked on setting button(the 3 dots), and selected usa band for radio band, I cannot receive any signal anymore.
Can I do anything to change it back?
Yes you can do the same dialing to get to that menu to change back to the proper bands... Change to GSM/LTE...
Hello everyone. I have a Cricket (GSM) Desire. I am trying to use it on the Straight Talk network (AT&T). I have already unlocked the bootloader, and sim unlocked the device. I have the correct ST apn set up. The issue is that it always shows an X in the signal bar, as in no service. Occasionally I will get the LTE symbol with 1 bar, and during that time my data is working. I can download from the play store, and send text messages. I cannot, however make calls. I will dial a number and hit send, and won't get a dial tone, and it will not connect. After 20 seconds or so I get a beep and it disconnects, and I lose service for some time. Under the *#*#4636 menu, network is set to GSM auto (PRL). I can change this setting, but it doesn't persist after a reboot. I have called customer service and they insist the device is CDMA only. I know this is the case for the Boost/Sprint Desire, but I was under the impression that the Cricket version was GSM. That's the whole reason I bothered unlocking it. Phonescoop is showing that the Cricket 510 uses these bands:
LTE 2 / 4 / 5 / 7 / 17
WCDMA 2 / 4 / 5
GSM 850 / 900 / 1800 / 1900
In my area, the AT&T side of straight talk uses the 850/1900mhz bands.
I can't figure out why this isn't working. The phone never attempts to connect to anything other than LTE. Any help would be greatly appreciated!
I figured it out. The phone had been dissasembled previously to replace the lcd. I opened the phone and found that the antenna wire that runs from the top of the board to the bottom was disconnected. Hooked it up and everything works properly.
Hi all
Accidentally changed from service menu *#*#4636#*#
Bands to usa bands
Now lost signal. Can someone help me how to get signal back? Live in europe and I thinks its a cause.
"accidentally", i really doubt. since the phone doesnt accidentally dial the service code and change the info by itself.
Accidentaly clicked on us bands mode. Was trying to get battery temperate but wrong clicked on the first option
Dial *#*#4636#*#*.
Tap the three dots on the upper right.
Tap on "Select radio band".
Select "Band 6".
Exit.
Reboot.
Test the phone and data connections.
If the tests are successful, then you've restored the Nexus to working condition. Otherwise, repeat the steps above, but select "Band 7". If that still doesn't work, or the other band options are not available, flash a radio through recovery. According to this post from 2011, flashing the radio resolved the problem.
This isn't an answer...
Updating to androin n preview worked. Changing bands doesnt work. Custom roms like purenexus wonna help also seems like bug in android
Hi, is it possible for me to change (and stay that way) the LTE bands on my phone without root? My network seems very slow on band 5 LTE and I'm looking to change it to band 38 or 40 instead. Thanks
Base on my experience, it's impossible not to root your phone and change system files.
I already have both bands on, it's just the matter of preferring one band over the other. I tried manually to search networks in the advance tab and managed to connect manually for a minute to band 40 network before it automatically changes back to band 5 ( even i selected thr the network manually)
Hey guys,
xda still going strong. nice to see.
need some help though.
i bought a note 8(yes in 2020) for some reason(side device) and i got stuck with a problem right away.
i noticed that TDD LTE bands(band 34,38,39,40,41) are all missing from my device.
i am having an exynos varient (n950f)
i was monitoring my network from past 2 days and 3ca was working fine. i was connected to 3,5 and band 40 all together.
i wanted better reception so went in network selection mode and selected band 5 preffered. i dialed *#0011# to check my ca status and i was still transmitting on all 3 bands with speeds well over 100mbps.
after some time my speeds died and i no longer see band 40 in *#0011# menu and i have tried restarting device and what not but still cant connect to band 40.
i am pretty sure TDD LTE bands including band 40 was missing from band selection menu earlier too but things were just fine. not i am stuck with a expensive device that fails badly.
please help.
on some inspection i observed that my phones is continously doing 2ca even when using no major data on band 3 and 5.
basic is stuck on band 3 and s1 on band 5. me changing to whatever setting in band selection in hiddennetworksetting dont affect it.
tried selecting bands that my operator dont even support. not in preffered mode but as the only hard selection. makes no diffrence. network signals shuts for a second and i am back on band 3 and 5 combo
