No SIM on LEX727

So I tried several ROM (CM13, Google EUI, Stock) when I tried to revert back to stock. Immediately after rebooting I noticed an issue: the bootloader was in Chinese. I thought it might be fine, but when the phone booted up, the SIM (AT&T) was not recognized. The option for "Mobile Networks" is grayed out and even CM (from a backup) has this issue now. I already flashed the US Modem zip and it is still occuring. Anyone able to help?
Update: Fixed 100% by flashing old stock firmware of EUI and OTA updating to 20s. Bootloader and modem fixed.

Nexus 6p calling issues, please help

Hello,
I have an international version Nexus 6p. While I was in Panama I accidentally removed the OS using TWRP, after rooting. I reinstalled the latest OS, TWRP, root, and used a custom ROM. I was dumb and didn't back anything up.
I couldn't make phone calls or access the internet with my phone on the network I used there, but I could with WiFi so I chalked it up to the ROM. Removed that and did a fastboot factory reset. I still couldn't make phone calls or receive them so I figured it was the network in Panama.
When I got home I still can't make or receive phone calls. I can text, and access the net but the service is very unstable. I am using cricket wireless, and I know it's not the service because the Sim was in my gf's iPhone and worked perfectly, and my friend has cricket and his is stable and works perfectly. I am running the latest Android 7.1.2 and would love some help with this issue.
I have tried flashing a new factory image, erasing modemst1 and 2 through fastboot, changing bands, using a different Sim card, factory resetting in general.
I have not tried another ROM (read somewhere that chroma would fix the issue, but don't really wanna jump back to 6.0.1 unless I have to).
Thanks for any help.

Le Pro 3 "No SIM Card" bug

I've had a few mobile data related issues on a few different ROMs now, and am looking for any solutions. The first problem I've been having recently is where my phone randomly reports that there is no SIM card inserted and won't make or receive calls and cellular data doesn't work. Simply rebooting or removing and re-inserting the SIM will instantly fix the issue but I'd prefer to find a solution so I don't have to reboot my phone all the time. Another new issue I've noticed is where the signal strength remains constant but the "ASU" goes from 40 or so to 99 and my bars appear to drop to nothing, this issue may have only started after my most recent install of lineage. I have the US variant of the phone and currently have Lineage OS 14.1 but even when previously on an unmodified copy of EUI 21s, albeit after installed after a few other ROMs, I was getting this issue. Does anyone have any ideas why I might be having these issues, or any ideas on what to try to fix them? Any insight is appreciated!

in my case I have the x722 and this does not recognize any SIM at any time

Did you try factory resetting? Are your APN settings for your carrier correct? It could be a lot of things. If you bought it in the U.S. from a U.S. store, you'll probably be able to RMA it (easier than the rest of us, at least). If the issue persists, I'd say open a case and ask for a replacement because it's your best option.
When did these issues start? From the beginning? If not, did you flash the modem correctly?

I don't remember exactly when I started having these problems to be completely honest, I just know that on EUI, after once flashing to lineage then back to EUI, I was having issues with it saying NO SIM INSERTED and now after flashing to Lineage and re flashing the 19s modem I am still having issues. I suppose I can try to RMA since I bought it at launch on LeEco's US store. Though I may have passed a year of ownership so I may be out of warranty . I don't really know what else to try, maybe this?

My understanding of this phone is, flashing stock rom (either US version or CN version), whose size is about 1.4g bytes, can give you the modem.
All the roms developed here do not have modem images.

I have faced the same issue trying installing custom ROM while sim card inserted.
The solution for me is to remove the sim try completely
Fastboot this (chinese stock) rom : https://drive.google.com/uc?id=0By_Lx-WrwGa7cnZMZWF4QUdmQm8&export=download
complete the installation normally using your wifi and then insert sim tray with sim. Hurray ! I got that working.
With this chinese stock rom I got everything what I wanted google play store, assistant and etc. (except android > 6)

First thing don't flash this ROM is not a good idea bad advice.
Try flashing 727 19s modern backup all on computer and do a hard reset.
Let know if this helps?

Haven't tried 727 19s modem backup, but what works for me is this ROM.
I know this ROM is in chinese and you might struggle on changing the stuff but when I faced the issue, the only thing I needed is to make the device usable whatever it'll cost.
It'll be great if modem backup thing will work for anybody. This ROM might be the last option for you.

If you flashing that ROM with their firmware if you have a big problem you can't fix it you are bricked 727 pro users should flash that firmware ect!
Their averaging one brick a day flash your own firmware stay safe.

No network access (Moto G5 Plus)

Hi everyone,
I've been having a problem since yesterday morning. Everything seemed to be fine with my phone before I flashed a custom rom. I was using at the moment MSM Xtended and I flashed the latest version of CrDroid. After flashing that other custom rom and booting, my phone had no network signal. All it reads on the status bar after that is just "No service". Of course, I removed the SIM card and reinserted it many times but that did nothing.
I've already tried flashing another rom (the latest AICP rom) and even going back to the one I was using at the beginning, but still nothing. I even tried reflashing the NON-HLOS.bin file and erasing modemst1 and modemst2, but it didn't do anything either. I also tried flashing this deodexed stock rom and booting. Interestingly, that kind of fixed the problem, since it recovered its network functionality. However, after reflashing an Oreo custom rom, it loses it again (actually, I've done that a few times today, but the last time I tried flashing the stock rom, for some reason it didn't fix it anymore). I don't know if in this case it's worth mentioning it, but I've tried checking my IMEI on both, custom roms and stock rom, and it's never been 0 at any moment.
TL;DR: My phone lost its network signal after flashing a new custom rom and I have no idea why. If anyone could somehow help me, I'd be really, really grateful.

I have had this happen so many times it is not crazy LOL. The best you can do is find a rom that it happens the least. For me it has been AOSP extended. Signal has been great. It is a bug that I dont think the devs even thought would happen with 8.1 roms. It will happen to everyone at some point if we stay on these 8.1 roms i guess until we get a workable 8.1 stock rom. There will be those who chime in saying it nevver happen to them but it will eventually.

Well, it's nice to know I'm not actually the only one then, I guess. But is there nothing I can do? Since I can't seem to get it fixed even by flashing the stock ROM anymore and flashing AOSP extended didn't seem to help at all either

I know brother there is no rhyme or reason it just happens. I am hoping when 8.1 stock comes out for us there will be a new batch of 8.1 custom roms without this problem. Right now i am on extended and havent had any signal problems for a few weeks so who knows.

Okay. Luckily enough, Oreo stock ROM doesn't look like it's gonna take too much more to arrive... Or so I hope, at least. Thanks

I was using LinageOs and it was working great. Then I decided to install DolbyAtmos and for that I flashed Magisk . Suddenly i had no network but my sim cards were detected , IMEI was there but no network on either sim whatsoever. I tried reflashing the LinageOs and PixelExperience ROM but none worked. So I tried flashing(ADB) the stock firmware only to lose my IMEI . After reading this post I tried Debloated ROM and my network was back. I should have stopped at that point but I tried to return back to stock again and lost IMEI again and now I have tried Dbloated,LineageOs , PixelExperience , AOSP Extended , but none helped me getting back network . Now I am stuck with this phone with no network , I had a backupp of my system before I flashed Oreo ROMs (with EFS) so I can get IMEI back but no network. This phone was my daily driver and now I have no idea what to do.

Everything you said is exactly as if I had written it. I did all of that and now I'm exactly in the same position. No idea how to fix it yet. Still, if you managed to find a solution somehow, please write a reply on this thread again

No success yet , but read on some posts that different baseband could be an issue.

Solution I've tried and worked 100 %
Hi bodies,
You can turn off your phone,
Go to fastboot menu by pressing and holding power button and volume down button in the same time.
Roll to "Restart Bootloader" with volume up/down and validate with power button.
Now select start and the network is back.
see you !:fingers-crossed:

Moto X Pure Modem Not Working

Hello I really need help I was flashing customs roms and I did something in ADB and now my radio doesn't work. My Moto X will detect my phone number and my IMEI number shows up but nothing else happens. Some roms won't even register my sim card. I tried flashing the modem from the stock 6.0 image on Motorola's website and I even used the modem files from the Nougat image here on XDA and and I can't get my sim to work. I tried multiple roms and nothing will work. If anyone could help I would greatly appreciate it.

If anyone is reading this I found a solution by myself. My modem was basically bricked so I used this link https://forum.xda-developers.com/moto-x-style/general/xt1575-moto-x-pure-edition-factory-t3704142 and reflashed stock Nougat using adb then I just reinstalled my custom recovery and rom and everything was working again.
