A little over a week ago I started having the fairly common issue on my (hitherto completely unmodified XT1039 where the radio is turned off and can't be turned back on again.
Following advice from similar threads on this forum, I unlocked the bootloader, installed TWRP and flashed the stock 5.1 ROM found in this thread as Retail EU 5.1 ROM (Optimized) v1.1: https://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-lollipop-rom-t3142816
Didn't get anywhere so I flashed the radio firmware provided in that thread. Symptoms remained the same:
5.1: SIM reads fine, WiFi works, radio off, IMEI reads fine
Following another thread, I tried downloading the stock 4.4.4 ROM from https://firmware.center/firmware/Motorola/Moto G (1st gen-2013)/Stock/XT1039/
Being a beginner, I ran into difficulties with manually flashing the xml.zip ROM - but on a hunch I tried flashing the radio firmware only.
Surprisingly, this worked - kinda. Having done that, I had a system where the radio worked - but the SIM wouldn't read, and the WiFi wouldn't turn on. I quickly figured out that I could switch between the two states by flashing the 5.1 or 4.4.4. radio firmware:
5.1: SIM reads fine, WiFi works, radio off, IMEI reads fine
4.4.4: No SIM, no WiFi, radio on, IMEI reads fine
Running out of ideas, I tried flashing LineageOS, only to get yet another configuration:
Lineage: No SIM, WiFi on, radio on, IMEI won't read
However, with Lineage running, I could flash the relevant 5.1 or 4.4.4 radio firmware to get those states back.
Finally, tried installing 4.4.4 from https://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-kitkat-rom-t3160127
This gives me the same set of symptoms I had originally (SIM reads fine, WiFi works, radio off, IMEI fine), whatever radio firmware I flash.
I am at this point pretty stumped - this is my personal phone so would be pretty pleased to get it up and running again. Any kind souls have useful ideas on what my next steps should be?

Baseband version I9023XXKI1 (from System Settings>About phone)
Bootloader version I9020XXKL1 (from bootloader screen)
Kernel version 3.0.8-g6656123
I have been using my Nexus S I9023 with official OTA 4.0.4 (and 4.0.3 before update) with no wifi or network problems. Yesterday however I decided to unlock bootloader, gain root access and flash a custom rom for performance/battery life purposes. I flashed CyberGR-MOD v.11 with the stock kernel and radio with CWM, with no other add-ons flashed.
It went well except for the fact that wifi has not been able to turn on since the first reboot. The switch will attempt to slide to 'On' but flickers, and hangs on 'Turning Wi-Fi on..' It makes no difference whether the SIM is inserted or not, Wi-Fi just does not turn on. Under 'Advanced' WiFi settings, WiFi MAC address and IP address are both Unavailable.
I have been searching for fixes for the last day, such as the WiFix apk found on this thread (http://forum.xda-developers.com/showthread.php?t=1445766) but nothing has worked. I have tried flashing other ROMs, reverting to stock OTA 4.0.3 and relocking the bootloader to return the phone to stock, but WiFi will not turn on in any configuration.
Portable WiFi hotspot also will not work, with merely 'Error' being reported when I try to turn it on.
Is the disparity between bootloader/phone stats regarding baseband version an indicator that I flashed incorrectly? Is it a radio problem?
Would greatly appreciate some speedy responses as I cannot seem to find any solutions to this particular problem.
[EDIT] Fixed problem by installing new kernel, was not able to do this before as my version of CWM was bugged and required an update. From then on was able to flash new files, kernel was the answer!
I'm running the KitKat+ ROM I found in the development section plus faux kernel, I flashed over jellybean and applied fix v2 so I'm getting no problems uninstalling apps or entering security settings. Thing is when I'm at home or even outside I get really slow network speeds of about 0.4 Mbps down,and in settings-aboutphone-status it switches between hspa and hspa+,but down the road about 350 metres at my kids school I get up to 7 Mbps down,I'm just wondering what version of the moto g is this KitKat+ rom based on,I own the UK retail version and was thinking if its based on a us version would it cause problems with connecting to a UK network or have problems with hspa+ in the UK based on what base this ROM is using,just throwing it out there.
Have you tried setting it to GSM auto (PRL) ?
My previous phone (HTC One X+) was running BlackBean rom and was set to CDMA by default, meant that i had to reset to GSM after every reboot.
I have experienced this also on a UK XT1032 running US Global GSM 4.4.2 - Data works but often slowly and stops entirely for periods of time. I had assumed it was the ROM and I'm waiting for the UK 4.4.2 stock firmware image which I expect will solve it. Perhaps unrelated, but I've noticed Opera Mini will not work over 3G in this ROM, but it works fine on Wifi.
EDIT: I was just thinking; that by fastboot flashing the Stock US firmware image, the UK modem firmware may also have been replaced. That could explain the problems. Flashing back the 4.4.2 UK modem firmware might fix it.
My Baseband version:
MSM8626BP_1032.340.63.00R
Can someone with a US Global GSM XT1032 confirm their Baseband version? Nevermind, confirmed via google. UK Tesco XT1032 running 4.4.2 also has the same Baseband version.
You could try flashing the UK stock 4.4.2 'NON-HLOS.bin' which appears to include the modem firmware. However if I remember correctly, flashing an incorrect radio firmware is one of the few ways to irrecoverably brick a handset.
Safest bet is to wait for the full UK stock 4.4.2 firmware image and fastboot flash that. In future when you flash a different ROM, i.e CM11, you are likely to use CWM/TWRP and the existing UK modem / radio firmware will remain untouched.
If someone wants to correct me on this, please do.
I'm new here but desperately need help. A bit ago I purchased a new Moto G from Boost Mobile, and activated it, the xt1031 cdma variant. It came with 4.4.4, however I installed the 5.0.2 soak test by putting the zip in the sd and installing via stock recovery.
I decided to go back to kitkat. I flashed the stock boost 4.4.4 firmware, no fails, all OKAYs via fastboot. However, the rom would not boot, it would be stuck on bootloader unlocked screen. I tried various times with the same result. I wanted kitkat so I read somewhere that someone had flashed xt1033 asia firmware and flashed xt1031 radios and it worked. I tried, to no success. I then tried to go back to the soak test 5.0.2 this time via custom CWM 6.0.4.7. It formatted system. It booted up but had no radio or signal, no network, even the MEID showed as 0 and everything else including Carrier, phone number, PRL, etc as unknown. Only wifi worked. I tried flashing the 4.4.4 again, a deodexed from SuperR (which I had flashed before). It boots up but now my wifi is stuck on turning on, wont turn on at all. Before this wifi issue happened I had flashed a xt1031 radios, and kernel, also tried a apn fix flashable zip. Is there anything I can do at all to get it back to ANY working rom but with working radios?
Same Issue
I have the same issue did you find out anything?
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.
My Moto G XT1039 (Peregrine) was running perfectly on CM 12.1 since July 2015. But two weeks ago it lost network access. This happened without any update or change on the phone. I tried the basic settings : reboot, toggle airplane mode, re-insert sim card... without any success.
Then I followed this thread to take it back to stock : still no network. After that I installed CM13 with this thread : network is back !
But after two days it lost network again. This time I swapped my sim card with another one : ok, problem solved.
For a few days only ! I then fastboot flashed this radio firmware : great, network is back !
And gone again... And now after flashing stock again, CM13 again, radio firmware again, it doesn't connect at all. Except from that everything works, including bluetooth, wifi and gps. The sim card is new and working in other phones. The exact error is : "Error while searching for networks" when I go to Settings | Mobile networks | Network operators.
I'm completely lost and I can't figure what is the root cause of all this. What do you suggest ? Is there a low level log file somewhere on the phone, in which I could find an error like "unable to start radio because XXX" ?
Thanks !
I installed CM13 once again using TWRP. And it's been running fine for the last 3 weeks ! I will never understand what the problem was...
It only loose network for a few seconds from time to time, but this may be normal.
The same problem occured again.
But now I'm sure it's related to the phone and hundreds of people have the same problem. There is a 96 pages topic on official motorola / lenovo support forum about it.
I can't link it here but it's the first result if you type "Post KitKat upgrade BUGs (Loss of signal etc)" in google.
