Hello,
LOS 17.1 2020-12-15 on a Moto G7 plus.
Installation went thru with no error messages.
NFC,Wifi works. But no cellular/mobile networking, no telephony, "no service" message at the top bar.
When trying to dail a number, I get the message "please disable flight mode", flight mode actually is disabled.
In the settings the SIM is detected, IMEI is detected.
Chosing different network types, like LTE,GSM did not help.
Is this a known bug in 17.1, or is this a device specific bug? Any hint what I could do? Downgrade to previous LOS version?
I read somewhere someone suggested to use
fastboot erase modemst1 +2
But that made things even worse (lost IMEI, SIM not detected at all)

So... I stared into the abyss, but I came back from the brink - unlocked bootloader, and the modem/calibration stuff got wiped during what should have been a routine TWRP flash from fastboot, and left me with no radios whatsoever. After flashing S048, and applying all the known OTAs up till S251, I got my wifi & bluetooth radios back, but it didn't seem to recognise my SIM (tried both slots).
After trying for almost a week, I also finally got the diagnostics mode going and was able to put a working QCN backup in place (thank you XDA and uploader).
So I flashed the LineageOS 15.1 20180413, and lo and behold, it sees the SIM and asks for a PIN to unlock it. So far, so good. Then (first time) Android says 'switching to mobile data, might take a while' but nothing really happens (I am on wireless; if I turn off wifi that doesn't make any difference though).
Under 'Network', 'Automatically select network' is enabled but 'Network' (right below) is greyed out. When I untick 'Automatically select network', it says 'Error while searching for networks'. When I re-tick it again, it says 'Registered on network', although nothing really happens.
Under SIM cards, it says slot 1 is populated, but says 'Mobile Vikings is disabled' (Mobile Vikings being my provider). The button to enable it is greyed out. Switching to airplane mode doesn't force anything either.
I've had a logcat instance open when toggling 'Automatically select network', but nothing related seems to show up. Any hints on what I could try/check? Or is this a coaster?
I believe that once you erase the modem stuff you'll always have serious problems restoring it. It seems like most people have to send the device in for service.
I've still no solution for an old P2 of mine and in that case I even had a TWRP backup.
Lenovo should really allow for us to flash stock images . An unlocked bootloader with LESS privileges makes no sense.
Wipe everything in twrp & flash twrp full backup which included efs & modem shared on our p2 forum. then flash Fastboot s48 only systemchuncks 0-14, boot & recovery then do 4-5 OTAs updates till latest one s251, you'll get you mobile network & calls back.
@eried1 Yeah looks like it
@amansehdav I have turned the P2 subforum upside down and I already tried this - restore a working S233 TWRP backup, flash S048 through fastboot, and upgrade with the OTAs till S251. No dice. Wifi and Bluetooth came back with that process, but the stock firmware would not see the SIM.
UPDATE: 4G/LTE wouldn't work without erasing all possible APNs except Ting's (with some messing around to get settings correct). LOS14.1 continued to throw errors with this install though so ultimately re-flashed with RR and it's working perfectly now.

I'm trying to port an S4 Mini SPH-L520 (CDMA) for use with Ting. Has anyone successfully done this with full access to phone, text and data? Having updated the carrier settings while stock, then flashed LOS 14.1 I've got functional voice, SMS, WiFi and can see 3G sporadically when I refresh network settings, but 4G/LTE's a no-go -- I get a "Your mobile data service couldn't be activated" error from the setup wizard every time the phone starts. It's definitely seeing Ting's SIM card because it's showing the correct ICCID, but won't work at all in RUIM/SIM mode ("No service", "Select SIM Card" with no options) and defaults back to NV. Haaaalp? I'm very computer literate but cell phones are terrifying and mysterious black magic...
Hello,
I just received my Razr 5g and I have a question about 5g setting. I cannot choose 5G in the network mode setting, see attached picture, only 2G, 3G and 4G, is it normal ?? someone have 5G option available ?
Best regards
US Unlocked
Ok thank you !
NIco
Just got my Razr 5G
So I popped in my nano_sim card and booted up the phone. As it went through most of it's installation and download files, I went into the settings window and I have a similar window in that it has the option that says just "prefer 5G network" all on it's own.
By the way, I am in Canada on the Rogers network living in a 5G covered zone.
Cheers,
Vodafone UK with the expected network options of 5,4,3,2G / 4,3,2G / 3,2G / 3G / 2G
You can read my post here:

Lenovo/Motorola Rescue and Smart Assistant (RSA) saved my Razer 5G and upgraded it to Android 11 with added 5G option in network settings. I had only up to "prefer 4G" option under Android 10 latest update with february 2021 security patch. And it wouldn't see any Android 11 OTA update.
If you have the same issue, hit the link below and download the "Rescue and Smart Assistant" listed in the Help topics (and the USB drivers if not already installed). Then start the program, create and/or log in with your Lenovo account. You can now connect your Razr to your PC, with your USB cable and USB Debugging enabled in developers options (and probably also OEM unlock). Hit many times in the row the "Build number" under "About your phone" in the settings to activate developers options.
It should then ask you on the phone if you want to connect to this Windows PC bla-bla, click on always and accept.
You should now see Rescue and Smart Assistant connecting to your phone and asking you to grant some accesses on your phone. When you did so, the program will show your Razer's informations under "My Device" or "Rescue".
Under "Rescue", you should be offered the option to rescue it by downloading the corresponding latest firmware. My device wouldn't start beyond fastboot mode or system error message, but it still got recognized in fastboot mode and I could save it this way.

I have a German Razr 5G model XT-2071-4. And I can now confirm it happilly connects to 5G network where it's available. Only problem is that the internal antenna seems to have a weak reception quality, at least in 5G.
Maybe this information was already posted elsewhere in the forums, but I think it's important to have this information instead of staying locked under Android 10.
I just bought this phone and installed LineageOS 17.1.
Dual SIM / 64GB / 4GB version
I pretty much followed these instructions: https://asineth.ml/post/android-rav/
One issue I ran into was that the "OEM unlock" option in the UI was disabled (greyed out) because you need to be online for that. After connecting to Wifi i was able to continue.
Another issue: I couldnt execute `fastboot reboot fastboot` because my adb/fastboot binaries were to old. I followed https://wiki.lineageos.org/adb_fastboot_guide.html to get the latest versions.
I do experience some small bugs that I also had with 17.1. on my previous phone (Moto G7 Plus)
- cellular data stops working for some reason, turning mobile data off and on again fixes the problem until it occurs again.
- sometimes i cannot click "Read" on text notifications in the notification area.
- the signal cellular bar appears with a little x in the bottom right corner and I dont know what the x is supposed to indicate.
feel free to ask for help if you have the same phone and get stuck in the process.
cheers
sadly more bugs
- if I turn off wifi hotspot the phone freezes and reboots
- sometimes the phone swallows text messages that are sent to me
Modem always crashes especially when outside. As long as I am at home on wifi, it seems to work, it crashes but not a lot (sometimes even during the night). But going outside and the phone switching to cell/wifi/cell/wifi/etc make it crashes rapidly.
Easy to see because I am losing voice/data. Phone does not reboot.
My F3 is stock, stock rom, never been unlocked or anything. It did this last year already. I am using the latest MIUI 14.0.4.0(TKHMIXM). I'm in Canada with PublicMobile.
error is
modem subsystem failure reason: ssr:MP:rflte_dm_rx.c:8779:rflte_dm_rxagc_config_update_switchpoints_and_lna_offsets_in_d
I have a lot of ramdump, for instance right now I have

Any way to send ramdump to xiaomi?
Problem seems to be
"External
Modem sending a Fatal Error Interrupt, with a error that Rx Calibration
Data (basically a instruction for what modem have to do with a Band
Receive Commands) is missing, and External Modem calling a "kill itself"
mode because of it can't recover from it.Î’asically you go to
countryside, ur band switches from 20 to 3+7+20 and modem crashes"

Click to expand...
Click to collapse
Would disabling specific bands fix this? Is so, what ones?
In another thread it seems someone tried it and it changes nothing :-/
Dial *#*#663368378#*#* to access modem test tools suite, hopefully something there can tell you more about what is going wrong
It seems I cannot access "MODEM test tools" (aka Rueban / MTB) app on official ROMs without authorized Mi Account according to some search. It only gives me a black screen.
Well that's mildly frustrating. Sometimes theres modem debug options in city (dial *#*#6484#*#*) tucked away in the 3 dot overflow menu in the top right...
Unfortunately there's no such option here :-(
I have a lot of ramdump about modem crash, always the same error. I tried to email poco support but gmail reports back that the server refused connection or something...
