Select Radio Band Unsuccessful - LG Optimus 2x

I have several questions about my LG P990, when I go to 'Testing' mode (dial *#*#4636#*#*), when I select Phone information my phone signal/network suddenly blank for 5-6 seconds, it always happens. And when I go to Select radio band, it always give me unsuccessful message on whatever band I choose.
I recall these problems never happens on my previous Samsung android phones, does anyone have the same problems? Thanks for the reply.

The loss of radio signal is normal, as it seems that the phone tries to re-estabilish its connection with the network every time you enter that menu. As for the radio band, that hardly can be considered normal; did you flash a different baseband or are we speaking about a fully stock phone?

Hi,
I've always had this error when trying to Select radio band on my O2X... I've never tried when it was still stock (which lasted 1 day ), but I've been on BB405, 622 and 725 and could never select radio ba,d without error.

cannot select any radio band
when i try to choose any radio band from tablet information menu via *#*#4636#*#* ....for example if i choose AUTOMATIC..it says UNSUCCESSFUL every time
And i am not roooted..i am on stock
PLZZZZZ HELP
THANKXXXXXXXXXXXXXX A LOTT IN ADVANCE

Same problem.

So i guess ill just have to nvflash it back to stock a cupple of times and try to blame it on the "OTA"

[Q] many problems now no network

I have a p925g rogers canada. It had a problem while updating and was bricked, no lg logo, no vibrate, nothing.
I managed to revive it a month later using Smartflashtool and lgp925_ap.bin and lgp925_CP.fls and that got me the logo back but the phone would reboot in less than one second of logo appearing.
So I then used LG mobile support tool and did a recovery, it recognized the imei in download mode and now the phone is up and running on 4.0.4. with baseband omap4430/xmm6260 and build number is ICS and software version is p925g30c
This phone is unlocked. I put in a koodo sim card and no luck. I get "No service"
Under phone identity i get the imei, the imei sv, they are all there but my phone number is "unknown" and I can never connect to the mobile network.
I've read many threads on here, about 12 hours now, and I'm seeing "flash baseband" etc. I dont even know how to do that with an LG. I've done many sammy's and used odin and cwm/twrp so I do have some experience with the process.
I'd appreciate any help with this. Please don't point me to a tread that just says "flash a new baseband" I don't know how lol.
sorry in advance.

would you believe that I re-did all the apn and after about an hour, it started working,
Couldn't have done it without XDA
PS I hate cellphones.
Which is why I love them.

Hmm sometimes rebooting a few times after an update helps things work better. Well, good it works.
still wont do messaging, and drops the network alot, also getting "Reorganizing internal processes" when I try to call but it goes thru after a few tries. I may try a custom rom if I can ever get into recovery mode (it wont let me)
correction, mms is working sometimes just like calls. Factory reset a few times. no difference.
edit - no data whatsoever. All apn setting correct, all settings rechecked. network unavailable.
no IMEI & no SIGNAL (network)
Could someone help me?
I flashed my LG THRILL 4G (AT&T) with official stock P925 V30B rom (with SMARTFLASH) but lost the IMEI and no NETWORK. :crying:
What can I do now?
Thanks!!
Use Flash Tool. See link above.

HTC ONE HTL22 Radio Problem

I have a HTC J ONE HTL22 and a few days ago I lost my network signal completely. Contacted my network provider everything was good,bought a new sim tried that and still no network. The day I lost it I went into the service menu #*#*4636*#*# and into Phone Information and was just trying some different network settings. I clicked select radio band...and I saw Euro Band,Japan Band,US Band ,AUS Band ,AUS2 Band. I tried US Band to see the result and than i lost that menu ,now I only see Automatic, Cellular(800-MHz Band) and PCS(1900-MHz Band). When I try Automatic it says Unsuccessful. The other 2 successfully work but don't give me my network back? I've done a factory reset and still nothing changes. When I manually search for a network,it comes up blank. before it showed Bell,Telus,Rogers etc. So it's defiantly something with my radio.
My cell is UNLOCKED, S-OFF, CID-11111111, HBOOT-1.54.0000, RADIO-1.23.11.0829 and CWM installed,running stock 4.2.2. So I'm wondering is there a way to reset my radio or any help on flashing a new radio? Thanks

Thanks for the link. Today I tried to install a new radio through CWM. I pick the zip to install and after a few seconds it says complete...I reboot and my radio never changes. I've tried it through CWM and Rom manager. Am I doing something wrong?

This might be of a bit more value. It seems the prior link was for a different HTC One model. Above link is for M7. Check it out if you still need a radio/baseband.
I also realized your phone is a Japanese variant...I dont know if that makes a difference or not in compatibility, but I wanted to mention you could try using ADB to flash the radio/baseband instead of using recovery. I think you could also upgrade your firmware,which usually includes the baseband. Good luck...
Thanks for reply
Nothing help
flash radio through fasboot and TWRP does not matter
Same here...still no luck yet. Still have no network. Makes no sense why the radio bands cant be restored!?
many service centers, many ROMs nothing help

Cannot get a 3g/4g network signal after messing about with advance signal status app

was messing around with the advance signal status and messed up my verizon Droid Turbo. I went into additional info > phone information and selected the" select radio radio" option from the top right option menu. Selected on cellular and all network connectivity vanished. I tried to fix the issue with messing about with other settings on the app, nothing seemed to work. Did a factory reset and its still not showing any networks on global mode or any other mode. Can anyone please help me out with this? The phone isn't rooted so i don't know an app could mess things up this badly
What are some things you messed with? Was it just changing the CDMA and lte setting?

happens to me too and was the only solution
u must flash the radio from Droid turbo
if doesn t work flash the all firmware
can't flash any firmware on this as its not rooted nor is there a bootloader unlock for the droid turbo as of yet. Only thing i did was go additional info > Phone information > select radio band > Cellular
Could not rever back to original settings after that. I have tried a lot of other apps as well, changed from global to lte/wcdma, gsm modes too.
Maybe the app developer can help you, although it says that is not meant to be used on non rooted phones.

Hey Guys ! . Dont worry if u select radio band to cellular. Here i give u solution .
If ur mobile is verizon
then simply connect your phone with pc with data cable , then install software of verizon update assistant by clicking on a drive showing in My computer and also enable the option of software installation from your mobile .
Next step is opening the program verizon assistant.
Here u have to run the repair process.

After 10 minutes your mobile will reboot automatically.

How to get GSM signal back after selecting USA Band in *#*#4636#*#* ?

Hi I have lost signal due to accidentally selecting USA Band in *#*#4636#*#* menu. There is no other option other than USA band in the select radio band menu under phone info . I have tried factory reset as well as flashing the ROM after a complete wipe. I have even tried the hard brick recovery procedure. I have a one plus 3 T A3003 model from India and the phone is not being able to lock on to 2g and 3g bands only 4g seems to be working with only data and no voice. please help . thanks ?
Only way to get functions back is by changing bands again just like to did to break it, as these settings are stored in the NV registry, non of the factory restore methods will be able to restore the values back to defaults.
Update: Okey, I just went into that menu and I see three options. Auto, Europe and United States. And your saying you only see the last after you manually choose it?
I have an a3003 as well (German)
The menu on my phone shows on us frequenz
Tipping on it does not break anything 2/3/4G still works
I'm not rooted
Stock 4.0.1 OOS

Yes I only see US. I am on stock 4.0 nougat . you are on which rom ?
I also went back to 3.5.4 where i could see options like band 30, band 31 etc. but choosing any of them did not help.
thanks

I'm on Lineage OS 14.1, but with OxygenOS 4 firmware/bootloader base.
Ok I have found a solution. I reverted back to os 3.5.1 using the unbrick guide from https://forum.xda-developers.com/oneplus-3t/how-to/unbrick-unbrick-tutorial-oneplus-3t-t3515306 . Now there are options such as band 31 , band 32 etc. in addition to u.s. band now I started applying each and every band, the trick here is that the applying each band takes at least 1 - 2 mins. so you have to wait after each operation to see if the problem is corrected or not. Finally the problem got corrected on applying band 43 , so band 43 seems to be the correct configuration at least here in India . now 2g,3g and 4g all are working. the strange part is that in nougat service menu this is missing while it is present in the earlier rom's . Thanks
