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...

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.

hi there, my atrix does not want to register at operator.
My phone was always trying to use 2g cause of better signal.
I went to Admin menu (*#*#4636#*#*), changed to WCDMA preffered, but in about a minute it did not change. I tapped function key and then Select Radio Band, it was only USA - i tapped it.
So he do not even try to register at any operator.
but i can call 112.
there is no any band other thsn USA.
Our band are almost same
900/1800/2100
So at least some operators must register.
may be i can refresh the modem part via bootmenu?
Or is there a way to reflash the modem part?
thanx
motrola forum - https://supportforums.motorola.com/message/353262 same situation, but with other ppl.
i found a solution...
1. backup via CWM
2. phone reset
3. restore backup.
I have managed to screw up the radio (Choose USA Only as band in service menu and can't change back) on my XT910 Non EFIGS Retail. I’ve read that only way to solve this is to flash original SBP. But I guess I can't do that either as there doesn't seem to be a public available SBP for NonEFIGSRetail.en.EU. Am I correct? Or is there any other way to solve this?
I can't believe that there is such a way to basically destroy the phone in a few clicks
Did you try wipe factory reset from recovery ? It should do the trick.
Yes, didn't help. And now I used RSD Lite with http://forum.xda-developers.com/showpost.php?p=21285410&postcount=63 as the poster said it was the correct version. But now I'm on a different release, XT910.Retail.en.EU. Don't know if it matters, exept if I need to send it to warranty service though. But the radio works now at least
Just for future reference, I have success rapidly going between Airplane mode and the *#*#4636#*#* menu (using home key) to change the bands.
Eventually - you'll get it to switch. Takes a few tries and it needs to be quick.
Reflash the radio.img with the same baseband version using fastboot. Find the radio related thread.

[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
I've ruled out everything I could think of, and the best this did was just give me 4G (7MB/sec downloads), and not 4G LTE (used to get 35MB/sec and up).
Things I've tried (with proper wiping/cleaning cache, data, system, dalvik cache before every single flash):
1- Unlock the SM-G900T, and add the IMEI to my account on att
2- check with att that LTE is working
3- get a new SIM card anyway because I'm paranoid!!!
4- Flash NG3 stock on the device, flash it back to NCH
5- Root the device, flash TWRP, and CM based Slim ROM on the device, and com.android. ... error
6- flash back to stock
7- APN is correct, ATT Phone APN and LTE is selected
What I noticed now is that typing *#*#4636#*#* in the dialer does nothing, and I mean nothing! It just sits there.
What am I missing here? (besides the rest of hair I had left on my head)
RESOLVED: It was a brilliant att agent that messed up my data plan while switching IMEI numbers!!! Lesson learned; think outside the box.
Glad you got it resolved.
Please edit your title so people can see easily see that too.
This is actually a common result and one of the most basic trouble shooting steps would be confirming that your SIM card is properly provisioned for LTE.. which usually requires a call to the carrier to check your account settings from the carrier side.
Enjoy your faster phone.

I thought you aren't suppose to give att your imei if it's a tmobile device?
Hi,
Following a tips in an android newsblog (In France), i was visiting the *#*#4636#*#* menu.
By curiosity, I tap on the menu "Sélectionner une bande radio" (choose a baseband).
I've only a "United States" choice but after did nothing. I lose all my phone network.
Just the data work and the sms.
What can I do to this ?
I think to flash a baseband firmware but where can I find one ?
Thanks for everyone who could save my phone

Switch your radio band back to automatic? Go to *#*#4636#*#* and click the overview (3 dots) at the top right. Hit select radio band, then hit automatic. Reboot phone.
Thanks but no auto option for me :/
I've done a Factory reset but no change.

I try to put network in Only 3G or 2G and got nothing. Maybe that's why there's no call but sms and data. No VoLTE in France.
When selecting United States band (that I didn't want to do), i break the 3G and 2G connection.
Hi,
I've speak with the Motorola support in France.
In the hidden menu, i've selected the united states band so now I only received the LTE (the only which are the same than here). No 3G and no 2G.
And because We've got no VoLTE, I can't use calls.
And no method to revert this process.
Go in warranty...
Actually there should be a way, because I have the selection:
Automatic
Europe
Automatic
United States
You probably have to update to a current stock ROM so the modem firmware updates and you might be able to select a different baseband... all theory but if you still have the phone, it's worth a try.
edit: I'm using a custom ROM, so I may be wrong.
For you there is no way of using a custom ROM without having problems with warranty.
If still relevant, I made the same mistake with my stock Moto xt1650-03 and the only way managed to restore signal was by using fastboot erase modemst commands. Though I have seen people not recommending this method, it worked for me.
