Hi everyone,
First, thanks everyone for all the information I have found in this forum for the past few weeks.
Now my problem : I have a Moto G 4G XT1039 that keep losing signal randomly. The only way to get my signal back to call or receive sms seems to be a reboot of the phone.
I don't remember exactly when it started but I think it was around June. Until a month ago I never tried to root or flash my phone. I just used the official updates from Motorola. I live in France and the phone is perfect for me except this problem.
I read here and there that a lot of people seems to have the issue but I'm surprised nobody seems really pissed of.
I downgraded to 4.4.4 to see if it would solve my problem but it did not. I read that the signal loss could be caused by Android 4.4.2 so should I downgrade further ?
This weekend I flashed a nightly from CM 13, the problem is still here.
What can I do ? The problem seems to be related to the radio firmware, can I downgrade the radio firmware and keep a recent android or CM13 ?
For information my baseband version is m8926_309101.02.03.14r.
I'm not sure I post my problem in the good forum but it could help other people in my situation.
If someone has an idea....
Thanks
Firstly try the Stock ROM and Radio Firmware available here: http://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-lollipop-rom-t3142816 - follow flashing instructions to the letter - after this you can move on to CM13 if desired.
Well I have already done that, after I tried the 4.4.4 version.
I was on 5.1 then I downgraded to 4.4.4 then got back to 5.1 then tried CM 13.

Did you fastboot flash the Radio Firmware from that thread? Commands are in FAQ.
Yes I did. I event tried to flash the 5.1 radio firmware while still having the 4.4.4 android.
The baseband version I gave in my opening post is the last one for the EU region I believe.
Other Solutions to try:
1) Change SIM card / get a new SIM
2) Fastboot flash the Stock Factory Firmware Image for your phone - http://forum.xda-developers.com/mot...falcon-factory-firmware-t3110795/post64203816
Thanks, I was going to order a new sim card to try this solution.
I already flashed the latest stock firmware last week but i will try again from scratch to be sure.
Provide fastboot logs (copy and paste command prompt) when flashing the firmware image. Fastboot may not provide errors, "okay" can mean total failure.
Hi,
Just to say that there is apparently no more signal loss with the CM13 nightly from 12/11. I hope it will last.
In the end I didn't flash stock firmware.
Thanks again for your suggestions, I will come back if the problem is back.
One week ago I got sprint model (sm-g920p) used for one week with 0 problems,i decided to update marsmhallow 6.0.1 PB6.
I wasnt getting any ota updates even ota update wasnt in settings anyway.. so i updated through odin.
Everything was ok except service connection, no service,no data,no calls nothing. Tried search manually and auto but no luck. tried gsm or lte or cdma didnt work either. Did factory reset and network reset but no luck.
It supposed to be baseband or imei problem right?
*I've checked them but imei and baseband was ok.. but no carrier.
I decided to install another roms and kernels but none of them worked either.
I am out of US zone but my phone is unlocked.
Right now I downgraded to 5.1.1 (OJ7) through odin and everything is ok right now. ( carrier service,3g,4g,lte, everything works fine.)
I am so frustrated and need help, am i missing something here?
Has anyone flashed the NKG47L June Security update for Tmobile/Fi Carriers to their Pixel? If so, did you lose VoLTE or Wifi Calling or both?
Wifi Calling and VoLTE were working fine on N2G47O and then I flashed the NKG47L OTA to my Pixel, which I am using with T-mobile, and I can no longer make a call without dropping to HSPA, and calls will not be made over wifi anymore.
I have a Verizon Pixel that I am using on Tmobile, so it wont let me unlock the bootloader to flash another image. I cant flash the OTA for NJH47B because it says its older than my current baseband.
just wondering if anyone else has the same problem so I can know if its my phone or the update.

Yes, no problems. Currently running Dirty Unicorns. Wasn't on stock long enough to check if Volte and wifi calling was working. On Dirty Unicorns with tmobile June update, it's definitely working

Thanks.
would be good if someone stock could answer as well. I'd like to know if its just my phone before I wipe and start fresh
The volte and wifi calling issue I had was fixed by a factory wipe. Sux that I had to do it, but it's working properly now on NKG47L
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.
I have the same problem in austria.

Please post it in detail i n the Lenovo forum link from the first post of this thread. Let's make as much reports as we can there - we haven't seen any solution yet
RETUS Unit here
Only Band 3 works.
Everything else drops out.
(Been trying to downgrade to RETUS 7.0 ever since)

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.

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.

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.
Hi all,
Anyone tried to burn a SM-F721U1 device with sm-f721u firmware?
I remember doing it on a note10. Question is if it's still possible?
seems to flash just fine. I have only found tmo and u1 with july patch... are there others?
I tried. Mobile network get disabled. Grey out in status bar. I am using US Mobile services. I have to do a fresh flash A12 VZW build to get back working handset.
I was wondering this as well. I purchased my first unlocked phone and now I wait for the 13 update, while the T-Mobile version is already out. I am on T-Mobile, so I'm guessing it will work just fine. Will my phone still be "unlocked" if I flash the SM-F721U firmware?
