Hi friends,
i was playing around with the title code of this topic.
After entering *#*#4636#*#* in my x10,i selected phone information,pressed the physical menu key on left of phone,than clicked "select radio band". In that there was only option under the "set gsm/umts band" which read "usa band".
I selected that and instantly lost network signal. I live in india and the phone is of usa at&t unlocked.
Now i am not getting signal. I tried to press the menu key again but it reads "usa band only". Tried to manully select network,but no luck.
Finally i also did factory reset,wiped cache partition,reflashed my wolfbreak rom ,but could nt get signal.
What else can i try?
is there any one who can help?
IS there anyway to rollback to original/default settings/bands?
any chance that there is a restore, or similar button inside that menu? Have you checked this?

Okay, here's the fix - I found this out because I did EXACTLY THE SAME (curiosity killed this particular cat!!) and PRESD BUTAN (USA Band) without thinking, on my Japanese X10 (SO-01B), which, as you did, set my phone to the wrong band for Japan. Duh!
Anyway on to the fix...
1) Bring up the service menu with *#*#4636#*#* at the phone dialer
2) Select Phone Information menu
3) Switch the phone to FLIGHT/AIRPLANE MODE (I did this by dragging down the top menu bar on my phone which is running a custom rom)
4) Press the menu key and SELECT RADIO BAND - you'll see the complete list of country bands - do NOT select a band yet....
5) Switch FLIGHT/AIRPLANE MODE OFF
6) Select the country Band you require - you should now see a success message.
7) Congratulations on getting your cellphone signal back
Regards!

hi, does erasing the modemst mess with the phone's communication functionalities? some forums are reporting problems after erasing the modemst (http://forum.xda-developers.com/moto-g/help/sim-status-erasing-modemst-t3160579) but it was on a different device. I'm on lenovo zuk z1, and having the same problem. I would like to try this solution out if it does not mess with the communication functions.

Hi Brother,
I'm facing the same issue on my Nexus 6p in India purchased from USA. Do you have any solution to deal with this problem?
Thanks.
Omg! I posted this in 2012 ? After 5 years still people are facing this issue! As far as i can remember i had to reflash stock Rom to get it back to normal. Thanks everyone for replies
[Q] changing engineermode "band mode" settings on S7589 + request S7589 factory rom
I recently picked up a Star Kingelon S7589 from an ebay vendor. This is actually the 2nd one, the first one I had to return due to a hardware failure.
My problem: I'm in Chicago where I had no problem getting UMTS/HSPA speeds on the replacement phone with AT&T as my carrier. But AT&T's pricing is a major burn. So I switched to T-mobile.
But the replacement phone had its own problems. The stock factory rom had problems with the face camera. So I requested an updated rom from the vendor - idiot vendors gave me the rom for an entirely different phone! (an unrelated ZOPO model as it happens. Gave me a nice black screen at bootup while playing what I can only describe as Chinese Video Game Music. GRRR!). So I had to mess around with trying various roms from needrom and other sources. Managed to find a relatively recent rom that flashes using the SP_Flash_Tool at boot time, but I've been unable to sideload any of the mods via adb in recovery mode, though I can get adb working for app installation and shell commands when the phone is fully booted.
Now having switched to T-mobile I find I can only get about 2.5G speeds. I inquire in a few places and learn they only use 2100/1700 WCDMA-AWS for HSPA+ in the Chicago area.
Upon going into "engineer mode"->BandMode,
I find all four GSM modes ticked. But under UMTS modes the only ones selected are WCDMA-IMT-2000, WCDMA-CLR-850 and WCDMA-800.
The rest, which includes WCDMA-PCS-1900, WCDMA-DCS-1800, and the mode I believe I need to use T-mobile, WCDMA-AWS-1700, are greyed out, in addition to a few others.
So next I explored the Android Testing Mode, and selected the option to "Change Radio Band."
On my list I have "Automatic", "EURO Band", "JAPAN Band", "AUS Band", and "AUS2 Band".
No USA Band.
So my questions are:
* On "Change Radio Band," does the lack of a "USA Band" choice there reflect a limitation of the baseband hardware? Or could this have changed when I flashed the phone? (I only learned about EngineerMode and Test Mode after flashing.)
* Are there any ways to un-grey the greyed-out UMTS modes in EngineerMode, especially WCDMA-AWS-1700?
* Is there a utility to query the phones baseband functionality and display the actual capabilities of the phone, as opposed to relying on data displayed in "engineermode" and "change radio band"?
* Finally, on the main EngineerMode menu, beneath BandMode is a greyed out option "BSPTelephonyDevTool". Any info on what this is? Even if its not relevant to my problem I'm still curious.
For what its worth, post-flashing a new rom from needroms:
The face-facing camera DOES work. However:
* the default language is now Chinese. It was easy enough for me to navigate to the appropriate menu to change it to English. But I don't know Chinese. Phone is encrypted and about half the time after a reboot the boot-time password prompt to unencrypt the phone is in Chinese.
* the phone as it currently stands reports its baseband as MOLY.WR8.W1248.MD.WG.MP.V6.P4, 2013/04/12. (I dont expect that would have changed from flashing.)
* Phone perhaps incorrectly reports its model number as GT-N7102. I say perhaps incorrectly because GT-N7102 roms do not work on this phone. (Im not quite sure what was in this field before flashing, but I seem to recall it was something like S7589.)
* Build number is Star7589-2013/04/20 by laoxu321 .
If anyone has an english language factory ROM image for this phone I'd be grateful.
Also, at this point if I can't turn on WCDMA-AWS-1700, I'll probably offer the phone for sale.
Best,
stimoceiver
From my knowledge, it is a hardware limitation, I have this phone and I use tmobile and it only gets edge network speeds. But with AT&T I get H+ speeds. Amd regarding the rom, the model GT-N7102 shows up because it was put there by the rom developer. They used the Samsung Galaxy Note 2 model number. Also, for roms, you can find them on needrom.com I am using a rom called Saigon or something and it works great
Some while ago I unlocked my XT1526 by installing the "Network" application (which is relly the same as the test menu you get with a keycode on some Motos) from playstore, and selecting "LTA/GSM only (auto)" from the menu brought up there...
The phone worked in India on 3G, and now in Italy on 3G as well. Thinking I would be able to select specific bands, I went into the "Network" to select GSM/UMTS Band and ttried the possible settings (my phone was offering USA Band, Cellular, and PCS).
Total outcome - phone no longer works with GSM. So, I was clever....
Google doesn't yield all that much, best info was here => http://www.droidforums.net/threads/3g-network-disappears.111409/
There the Op eventually fixed it by flashing droid sbf from Google.
Regrettably, there's no such SBF (full firmware restore file) for the Sprint XT1526 available. Any other recommendations what I might do? I'd go for a full firmware restore, and there appear to be a few good threads on FW restore, but not for a Sprint model...
http://forum.xda-developers.com/moto-e-2015/general/stocks-firmwares-moto-e-t3113235
http://forum.xda-developers.com/showthread.php?t=2759495
http://forum.xda-developers.com/mot...e-restore-moto-e-2015-stock-firmware-t3044936
My phone is on 5.something at whatever Sprint currently is... Any rumors whether another update might be pushed out by Sprint soon that might "magically" fix this by overwriting the current FW and settings?
Final warning - there's not a lot of discussion about this option, but it seems it has caused nothing but grief for all that used it.
Thanks!
Unlock bootloader and erase modemst1 and modernst2
You are done.

Sent from my XT1093 using XDA-Developers mobile app
Hi everyone,
First post on XDA after years looking for solutions for my smartphones here.
I was playing a bit with my Archos 50 Diamond (dual-sim, 2015), in order to use it as my main phone, as my current one is slowly dying. I purchased a new touchscreen I replaced myself as the former one was broken, and tried to put my SIM inside. No signal.
I tried a factory reset. Still no signal. SIM was detected, asked for PIN, but no signal. After searching in several forums, I managed to arrive on Radio Info settings. (code through dialer is *#*#46363#*#*, anyway I cannot access any code through the dialer, don't know why, so I arrive there using an app downloaded on Play Store)
As I was playing around, I chose "Choose Radio Band" and selected USA Band. Big mistake. All frequency were gone (GSM, LTE) and the "prefered network" option is stuck on "WCDMA only". Of course, I live in France, we use GSM/LTE frequencies, so no signal.
Moreover, the "Turn Radio on" button doesn't affect the radio cells.
After a few factory resets, I already tried the following :
- erasing modemst1 and modemst2, through fastboot. It resulted only in erasing IMEI, great. I restored IMEI through "IMEI changer.exe" I found on the web. Both IMEIs came back.
- enabling all necessary bands through CDMAtool (or Qualcomm QSPT/QXDM tools, it's the same process, using Android Diagnostic Mode) - All GSM/LTE bands will appear on the smartphone using an app like "Network Signal Guru". After that, I can change "prefered network" in "Radio Info menu", so this is better that stuck on "WCDMA prefered". But the SIM is now undetected, no PIN is asked, so I cannot even verify if signal is back.
- Adb shell su -c "radiooptions [arguments from 0 to 8, 0 resets, 5 turns on)" _ using option 5 will actually turn Radio on, but no effect on if the SIM is detected or not. By the way, it turns radio cell for 1st SIM, but not for 2nd (we can see it in "About Phone, State" in phone settings)
- Tried to edit build.prop in order to see what I can do, but I couldn't see no effects either.
- Tried to flash NON-HLOS.bin, but didn't help either. I couldn't find fsg file inside my factory firmware image zip.
So for now, I know how to enable bands I need with CDMAtools, and turning on/off radio cell through adb shell or Terminal Emulator. However Radio Cell will turn off automatically on every reboot, need to turn on manually everytime I boot.
But SIM is not detected at all. I'm not sure if there would be some signal if SIM was detected, but it would be great if I could figure it at least.
Phone is rooted, STOCK firmware Android 4.4, no existing custom ROM, can boot into CMW if needed.
I've tried a lot of tutorials, I don't even remember which ones I did or not, but I'm pretty sure I couldn't find solutions on XDA or stackexchange at this moment.
If you can help, thanks in advance
Cheers
Samuel
Hello. is the replay to this post?
I have asus rog phone 6 and have same problem. after mess with "SELECT RADIO BAND USA BAND, cannot access internet. tried the soltioins from online bootloader erase modem. but not access. when I boot into bootloader it stuck on wait for any devices. asus rog bootloder does not have any settings, its empty.
anyone can help?
I can't get the data connection to work at all, and it won't even connect to a 4g network even when the signal is strong. Mine is a H930DS (Joan?)
I just reinstalled the stock pie using "H93031a_00_OPEN_EU_OP_1105.zip", I installed in TWRP. I followed the instructions on the first page of this thread .....
I have tried various custom roms on this phone but this stock pie is one of the very few that even recognizes the sim card. I settled on stock pie inspite of the bloatware.
The problem happens when the rom is brand new, before ANYTHING is disabled or removed.
When I choose to search for a Network Operator (using the 3 Network sim) I get a "3 RAT-4G" and a "3 RAT-3G" listed and it will never connect to the 4G if I choose that one. It will only connect to the 3G. Even when the signal is very strong (5 bars). When I opt to connect to the 3G network then I get a stronger signal if I choose "GSM/WCDMA auto" in "settings>>network>>mobile netwroks>>network mode" but still no data connection
THESE DIDN'T HELP
1 - using ADB and restarting the phone in bootloader. It was to reset the modem I think. There was a series of 3 commands to follow. i can't remember the details of this method but I think one of the commands included "fastboot erase modemst2". I tried it and I was getting the same error message that other people reported and it didn't go anywhere.
2 - The following solution didn't work either..............
"re-loading IMS settings using the LG Hidden menu: Dial *#546368#*930# using the stock dialer -> Field Test -> IMS Setting -> Test -> Load Preset Configuration -> Initialize Configuration. Then back out twice to Field Test -> IMS Setting -> Test -> Restart IMS process. Give it a few minutes."
3 - Resetting network settings didn't help either (Settings -> General -> Reset -> Network settings reset).
4 - Changing APN, or network bands (in settings ... choosing "LTE/GSM/WCDMA auto" or "GSM/WCDMA auto" or "WCDMA only")
5 - Changing "set preffered network type" in engineering mode settings (accessing using *#*#4636#*#*)
How can I use data connection on my H930DS?
Data modem works now!
SOLVED!
My phone has bootloader unlocked and TWRP revcovery. That's obvious I know but I only say it again in case anyone tries this with a locked bootloader and using a stock rom that has never been flashed. (I have to warn you that your results will be different, your rom will be reset for sure an your data will be wiped).
I tried so many things, flashing up and down from 8 to 10 but Stock Pie was always the least buggy for me so I persevered with that.
I think this solution reset the hardware, but I am no expert.
The solution is basically a "Factory Reset (R&D Only)". They warn you against it but with my configuration all it did was reboot the phone into recovery and then left it for me to decide what to flash or wipe, as per usual. What I only realized later, when I rebooted into system (without changing anything in TWrP) was that it had reset the hardware, or reactivate data connectivity. NowI have 3g data connection and 4g connection.
THE SOLUTION
*the following 4 lines are a direct quote (my phone's os DID NOT reset)
1) Backup everything, as the phone will be wiped. If yours is a network unlocked carrier model, make sure you have an unlock code (or unlock approval if T-Mobile).
2) Remove your Google account to disable Android Device Reset Protection.
3) Dial *#546368#*930# (replace 930 with your model number). This should open the service menu. From there SVC Menu - Factory Reset (R&D Only).
This takes quite a bit longer than normal Factory Reset. Your phone is now TRULY back to factory state.
I took out the sim and sd card before I committed to the reset. But like I said, it didn't wipe anything (maybe it would have wiped my sd card but I am not testing that). It just booted into recovery and when I rebooted into system I found that the data connection was working. Now finally it is a smartphone!
