Hi All,
I bought XT1225 on ebay and I can't return it. So when I run on 4G network, everything works fine until I go into some places where is certainly no signal; After signal is gone, it can't turn on again. I tried to unplug the SIM and reinsert it, turn airplane mode off and on again, and nothing did the trick until reboot. I am using *#*#4636#*#* to check phone status, the GSM radio is off and I can't turn on it's radio even I clicked the button "turn on radio".
I am currently running latest version of stock rom. Anyone have idea why? and how to fix it?
after using logcat -b radio, here is the result:
D/RILJ ( 1668): [4364]> RADIO_POWER on [SUB0]
D/RILC ( 341): SOCKET RIL_SOCKET_1 REQUEST: RADIO_POWER length:16

What exactly is wrong with this radio?

Have you tried factory reset and a fresh reflash?

Hi there,
I have the exact same problem, and actually here is what caused it.
I bought Moto Maxx XT1225 from eBay roughly a year back, it was Puerto Rico version. Since early 2015, I noticed it lags at times. I also noticed the other varients of Moto Maxx XT1225 (Indian) got Lollipop update, however PR version still on Kitkat. Researching through Xda developers, and I knew my XT1225 PR version can be flashed with Indian firmware, and gain Lollipop update, as the internals are identical. I also hoped I'd fix the lagging issue of Moto Maxx, and clean up the device wish a fresh start.
But then, after I flashed with Indian firmware for XT1225, I noticed this issue which you're experiencing now. On 4G LTE, its all good, as well as on 2G. But If you're on AUTO mode, you'd frequently switch between 3G and 4G, and the issue comes then. At random times, when the phone switches to 3G mode, radio gets turned off somehow, and the only solution is to turn it OFF and then back ON. It happens only when switched to 3G cell, and doesnt happen always. I suspect this is due to some incompatibility of Puerto Rico radio and Indian firmware of Moto Maxx XT1225.
Go to SETTINGS > ABOUT PHONE > and check SYSTEM VERSION.
My system version: 22.34.11.quark_reteu.reteuall.en.EU.amxpr (ending with PR, hence Puerto Rico)
My Baseband version: MDM9625_104438.245.02.85p QUARK_EMEA_CUST (Previously, this also had PR in the version number, but after the flashing its gone)
While I flashed, I flashed radio as well as system and all other parts, but somehow this happened. I'm waiting for Marshmallow to my phone, will probably reset it and reflash the PR version. For now, I'm forced on 2G most of the time (on WiFi at home and office), and while I drive within the city, as cell switching between 3G and 4G happens often, and then radio goes off.
I believe flashing the original firmware might fix it, you just need to figure out which version your device was on before this happened. In my case, if Marshmallow gets delayed beyond December, I'll flash PR version to check again.

Thanks for your detail reply,
I tried to flash all other version of stock rom, only India 5.0.2 stock work without having issue with baseband version "Unknown", I couldn't turn on radio as you did, the only way to make GSM radio turn on is by reboot.
Anything we could hack around to make it work?

That's right, my phone is initially from Puerto Rico, and I flashed Indian firmware 5.0.2 back in September, and has been facing this issue since then.
When I'm on 4G, and when an incoming/outgoing call happens, the phone gets switched back to 3G, and sometimes radio goes off. Once this happens, there is no cure, but to restart the phone. To prevent this from happening right after restart, I switch to 2G ONLY mode, and then reboot, and can make calls and send SMS. Like I said, I'm tethered to WiFi most of the time, and whenever I really need to browse, I force to LTE only with the USSD code *#*#4636#*#*.
I think this problem has got to do something with baseband version respective to the firmware region. Any clue as to what your phone initially had, was it Mexico, Brazil, Puerto Rico or Indian?
If I find any cure to this, or a more permanent solution, I'll post it here.

I have no idea what's the original region of this phone. I am guessing India because all other firmware baseband doesn't work.

No, I believe its got something to do with firmware compatibility with radio software. All these problems started after I flashed it with Indian firmware.
In addition to the random radio off issues, my device randomly reboots while I'm in the middle of doing something. It gets damn slow at times, and then phew, reboots. Random freezes do also occur, and I'm counting on Motorola to start rolling Marshmallow for XT1225, trying to stay calm until then, so that I can try the new firmware, and if that doesnt solve it, can downgrade to 4.4 for Puerto Rico, and install 5.0.2 OTA from there.

How do you downgrade? using fastboot or Motorola RSD lite?

I never used RSD Lite, sorry about that.
Download the firmware from the links, and I suggest you use 'Flash Firmware on Moto Maxx Using Motorola Fastboot' method.

I bought my mom a Moto G. The problem is, that once the phone gets out of signal, it won't connect any more the the service provider until I reboot the phone. I tried it with 4.3 and with 4.4, but it didn't changed anything.
Should I try to flash a different RADIO?
I'm from Europe and I use a German version of the phone.
did you solve that? i'm with the same problem.

Could you tell us if your IMEI is equal to zero?
The provider specific SIM menu is available, but the tablet shows no signal. Even when it shows one, the signal disappears the moment I try to make a call or am about to receive one. The caller can still hear ringing while the tablet lists the call as missed call.
My father's Galaxy Tab 2 7" automatically tried updating through wifi but failed (I presume), and the SIM functions stopped working.
After many attempts I updated it through OTA to the latest firmware, shown as PDA:NA3 / PHONE:LK1 / CSC:NB1 (INU) in Kies, and the Android version was listed as 4.1.2., but the problem persisted.
I tried to wipe cache. It didn't sort the problem.
Then I Installed CWM 6.0.7 and Cyanogenmod 10.1 (JB 4.2.2) using this tutorial: wiki.cyanogenmod.org/w/Install_CM_for_p3100
Still it can't make or receive calls.
Baseband version is listed as p3100ddclk1
What to do?
Is this a hardware or firmware problem?
Hey brother,
Even I am facing the same order on my tab but in a different way. I can recieve signal for the carrier Tata Docomo but other carrier are showing any sign of life
But sometimes while on tata docomo , I lost signals while using data or when I got a call. And one more thing, I was on a trip to a hill station and there I was getting signals from Vodafone perfectly (my main service provider). But when I came back from there I ain't receiving any peice of signals from vodafone and Docomo is working as usual with few network losses during the day.
PS.- I ain't received any solution yet, still sticking up with that problem.
PPS.- The tab I brought is in used condition with the fact that the tab has that problem in it. (I need not to pay much lol)
Btw I think if we can flash new firmware (official) with odin with modem file, It may sokve our problem. TRY FLASHING FIRMWARE, I cant as I am low on speed

Hello guys,
Well I have the most indescifrable issue with my Moto g (xt1032).
It was aquired with kitkat, the day 5.0.1 GPE was released I installed it, making it a xt1033 GPE.
When Motorola´s 5.0.2 was released (brazilian) I downgraded to 4.4.4, and went ahead and installed moto´s 5.0.2 for the camera..
The next day, all was going ok, wifi, gps, moblie data etc.. not a single issue.... I had made calls, sent sms, etc... but around 12:00m (lunchtime) I saw "emergency callls only".... (I have not cutted the sim card to fit in the phone).
At that time, I swapped sims, (I´m on Claro colombia, I put a Virgin Mobile Sim..) and it worked again. I could call, send messages and stuff.
But yesterday That Virgin mobile sim stopped working, Now I face the following notification: Selected network (Claro) Unavailable.
I also get another notification about Resticted mode changed.
and yet another notification that says my sim card cannot be used to register on said network.
And another notification that says cannot send mms without registering something.
And another notiication about Voice service disabled...
this is driving me crazy....
The first thing I thought was of factory resetting the phone, to no luck, as my phone gets stuck at the red exclamation android and never goes to recovery.
I tried to install Phillz recovery but I get fastboot errors.
My phone is rooted btw, bootloader unlocked.
Is this my fault? as in I did a massive screw-up, or is it the software or is it a change on the provider´s end? I dont know.
What would you recommend doing at this point?
I have entered test mode and selected GSM only, but no luck.
Please, please shine a light on me, searching for no service and specific notification content only guides me to kit kat issues, which I really don't know are applicable to lollipop.
Mercí for your attention guys, have a good night.

Any Ideas? I´m in desperate need of using my phone, well you know.... as a phone
Hi,
This is my first post but, I'm an avid lurker. I am having some issues with my girlfriends 920i. It received an OTA update to marshmallow and ever since it won't read the Sim card. I've tried to flash the official fw through Odin and still having the same problem. Because it doesn't read my Sim card, I have zero access to any mobile network settings.
I am wondering if when they updated the marshmallow, I lost unlock capability.
Also, her imei and sn still match. Most of the problems I see people have are mismatched numbers, and her phone seems fine.
Any help would be greatly appreciated.
So, I checked the firmware that I flashed and it was INS which seems to be the locked version.
I flashed the INU firmware this morning but still not reading my SIM.
I'm out of options at this point, I'm going to go back to lollipop and see how that goes.
Hi,
I am having this issue for my SM G-920I since 2/3 Jan, 2017. I am using fine on US Tmobile network since Oct 2015, but all of a sudden got the no SIM, emergency calls only and continues to stay like this.. I am curious to know if you resolved the issue and how. Thanks for any feedback!
Help me please
I'm having the same issue. Just flashed INS 6.0.1 firmware on my brand new G920I and now i can't get any mobile signal or data. Tried to flash ZTO firmware for my country, but same issue. My phone was fine before flashing INS firmware. IMEI it's fine too. Recovery shows: Applied multi-csc. What can i do? ((((((((((

Already updated and tried to downgrade to 5.1.1, but no sucess. I don't think it's a hw problem, cause it was working before the INS firmware flash, and IMEI number still shows right, no matter what rom i flash (now on MIUI). Can i clean EFS partition and try to flash ZTO firmware again, or i might lost my IMEI and get more problems? Also, wondering if advanced wipe with everything checked on TWRP can help. (data, internal storage, system, sbfs, cache, dalvik cache)
Can you open the phone dialer and enter this code *#*#4636#*#* then clikc Phone Information, and send a screenshot of what you see in the screen (Make sure no IMEI in the screenshot, before you post it here) ? Also check if Radio is OFF or ON.

Codes on my dialer doesn't work, but i'm sure the IMEI is right cause it's showing in phone information. Also, radio is on cause when i search for mobile networks the carriers of my country appears on the screen but when i click on then, just appears a message saying that can't connect
Same problem, any solutions?
I had same issue for over a year, you can check details in my thread, resolved by factory warranty motherboard replacement (free of charge, even thou knox was tripped when I bought it, and I told lady in authorised repair shop that i don`t have warranty).
Forgot to mention that I also tried to repair it via Octoplus box, both by me and some other people (wanted a second opinion), DRK fixed, few new certs written, etc.), not only by flashing fw via Odin or Smart Switch.
And I was 99% sure it was hw, turns I was right.
P.S. country dependable: - in some countries they will probably want to sell you a new motherboard in Samsung (happened to me), but in other factory warranty will be accepted (probably, if the phone is not older than 3 yrs I guess)
Folks, wanted to leave you guys a heads up that some of us are facing issues with the phone not picking up a 4G signal, or picking a signal but not connecting to mobile data or VoLTE after the update to NPL26.118-20
Here's a thread I created specific to India and Jio 4G with Band 5 (850Hz) in the official Lenovo support forum - https://forums.lenovo.com/t5/forums.../Moto_Z/highlight/false/page/1/thread-id/2624
Here's one more thread - https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/Moto_Z/thread-id/2668/page/1
Before you upgrade, use LTE Discovery app to ensure you're not in one of these regions with an affected LTE Band!
Update to the issue - my phone (running 7.1.1) is only trying to connect to Band 5 FDD-LTE in the location where I am at, but does not manage a LTE/ VoLTE signal or connects but drops/ does not connect after reboot. I used another XT1650-03 that is still running 7.0, which connects to Band 40 TDD-LTE (same exact location, same SIM used in both the devices). My service provider is known to utilize multiple LTE bands in the same location, but it is weird that 7.0 connects to Band 40 and works fine but 7.1.1 tries to connect only to Band 5 - that too without success.
I am roaming in a location where both Band 5 and Band 40 are available. 1650-03 with 7.0 connects to Band 40, but 7.1.1 insists on connecting to Band 5 but fails.

There is no way to downgrade except for going in for replacement, and hope that the replacement device comes with 6.0.1 or 7.0, and not 7.1.1 - I tried this route with the Moto service already, and am thinking of going in for the replacement..

There are factory images available (for RETEU only 6.0.1 version is available), if i understand you correctly, downgrading by flashing the full ROM with mfastboot would not work properly...? I'm considering to just downgrade and wait for them to solve the issues with 7.1.1, since sending the device for repairs would be a hassle...

It won't flash the boot, recovery, and system partitions (among others), and will tell you that you cannot downgrade.
I took mine to the service centre, and all they can do is reflash 7.1.1 - they cannot downgrade either, only option is replacement and hope the replaced device comes with 6.0.1 or 7.0

Have you tried flashing 7.0 on it? bullfinch110 suggested that the bootloader changed from 6.x to 7.x, that's why you can't downgrade, but flashing 7.0 should be fine. [link]
For you i suppose instead of the RETBR, you'd need some RETIN firmware.

I did not find the retin such image, think I tried the reteu 7.0, but it failed. Let me know if you're able to get it to downgrade - but have at least the 7.1.1 ota handy just in case. What I've found is that the modem will downgrade - and will probably fix the 4G issue, but WiFi won't work.

There is no way to downgrade except for going in for replacement, and hope that the replacement device comes with 6.0.1 or 7.0, and not 7.1.1 - I tried this route with the Moto service already, and am thinking of going in for the replacement..

I unlocked the bootloader + used RSDLite to flash the retus 7.0.
Warranties be damned if it's gonna have to be ship it across the world.

I believe it shares software update line with REAPAC
At least according to this side:https://firmware.center/firmware/Motorola/Moto%20Z/Stock/XT1650-03/
Android 7.0 also missing LTE bands
Got my hands on an European Moto Z model xt1650-03 reteu, still on Android 7.0 with security patch of April 1st 2017, and am having LTE-reception limited to Band 1, 3 and 20, although provider and coverage indicate that band 5 and 8 also should be present.
In settings there is only 4g present, no enchanced 4g for LTE or Volte, although having activated those services through my provider (Vodafone CZ). The occasional 4+ is sometimes also showing.
Having read about the problems with the total loss of LTE for several users after upgrading to 7.1.1, I am very reluctant to make the jump before an eventual patch.
Any thoughts from other users with similar issues?
best regards,

After being thrown back and forth between phone support and service center, I have figured out the solution on my own. Long story short, use Baseband (NON-HLOS.bin) version M8996_1258.42.03.11R SID for retin considering it fixes the Jio 4G roaming issue. M8996_1258.42.03.11R is from retcn (XT1650-05)
As of build NPL26.118-20-5-3 (Oct 2017 Security patch), my phone has a Baseband version of M8996_1239.53.01.0126.04.01R SID, which does not work with Jio 4G if it is roaming between different parts of the country that uses different LTE Bands.
M8996_1258.42.03.11R SID works just fine - Jio 4G VoLTE works in roaming, Wifi and BT works too. When I need to update (security updates or to check if Moto finally fixed the problem), I flash the full firmware for NPL26.118-20-5, get OTA updates that came after, check if they fixed the issue (which they haven't till now) and flash M8996_1258.42.03.11R SID NON-HLOS.bin so that I can use my phone.
I also have my wife's phone with a SIM from the same Jio 4G network (in roaming too) that I have kept at 7.0 without upgrading to 7.1.1, only to prove to Moto service that the phone itself is fine, and its the update to 7.1.1 that messed it up. Her phone running 7.0 has Baseband version M8996_1239.53.01.126R SID and works fine in stock form. If I flash this Baseband version on my 7.1.1, 4G and VoLTE will work, but Wifi breaks.
Both the phones are bootloader-locked (never been unlocked), and not modded in any way. If you need any technical detail/ experiments, let me know - I am doing all that I can without unlocking my bootloader anyway.

How did you flash the retcn baseband to your retin model?

Code:
fastboot flash modem NON-HLOS.bin
Flashing the modem does not require an unlocked bootloader, so you can experiment with different modems - just make sure you are flashing modem versions from the different variants of XT1650, that's all.
September's 1+GB updated fixed most of the heating and LTE band issues.
You just have to fix the damage caused by the heating by replacing the batery.

Unfortunately, the update did not fix the Jio 4G roaming issue I'd described in the OP. And this is the only fix apart from staying with 7.0 that helps...
Finally, after almost 9 months of dealing with this problem, the retin update to OPL27.76-51 resolved the issue. The phone now readily latches on to Jio 4G when on roaming without me having to go through all the hassles I have been undergoing since I updated to 7.1.1.
