I'm using Droid Incredible 2 and facing a strange problem that I need help
My phone is using GSM network and rom Cyanogenmod 7 stable version
The phone works without problem until I restart the phone, the Baseband version becomes unknown and the notification shows the message "No service" so I don't have any mobile network
I tried to reflash the ROM and the problem seemed disappear. But when I perform a restart, I experience the same problem again
Is there anyone know how to solve this problem?

I would ask in the rom specific thread. You're more likely to get someone with experience with that rom to answer.

He can't post there most likely since he has only 2 posts. I had an issue with Viper like this but thought it was related to Hurricane Sandy....
One morning I grab my phone off the usb (computer) and it says Vodafone instead of VZW on the lock screen. Hmmm. Reboot and nothing changes. Can't send of receive texts or connect to 3g but phone works. I tried pulling battery, sim card....to no avail. As a last resort I wiped data and it has worked since with no issue although that forced me to re-install all my apps.
Hope this helps.

Thanks so much for your suggest. I wiped data and my phone works too. But I wonder what is the root cause of this issue? A problem of custom rom ???
I'll try to give as much information as possible.
Yesterday I was surfing the internet and suddenly my phone froze and randomly restarted. After that I wasn't able to connect to wifi nor bluetooth. I was running android 6.0 with 30B modem, rooted and with TWRP. After that I flashed Modem from v21C Firmware. I don't know if doing such was responsible for the next thing, but my Wi-fi mac adress and bluetooth adress disappeared from Hardware information. Note that my IMEI information did not disappear.
After that I did a full factory reset with .TOT method. That didn't solve my problem. Tried upgrading to lollipop, did not work. I've done like 10 factory resets only today, I've tried to fix persist partition following this guide http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576, same results.
In 4.4.2 and 5.0(all versions I tried from lollipop), both wi-fi and bluetooth adresses showed up as anavailable. Sometimes after rebooting, my phone would connect to wi-fi and show my mac adress, and would crash after 30 seconds..
On 6.0,my mac-adress shows as 02:00:00:00:00:00 and bluetooth adress as unavailable.. Need some serious help here, tried so much stuff nothing worked..
I'll attach some screenshots that may be useful
Any questions and any tries to help me are highly welcome.
Enjoy 6.0 on your phones and thanks for reading :fingers-crossed:
-------------------------
Edit:
Adding some logs. Half a year passed, no solutions.
1 out of 100 reboots wifi works. I've gathered some logs of 1 of the moments wifi works. Hoping someone can figure something out. Tried lots of roms, nothing seems to work.
Forgot mentioning that both wifi and bluetooth show as trying to connect on notification bar, but when I go to settings and press on them, both say "turning on (wifi or bluetooth)" when the button is grayed out and off..
did you tried to use the cse flash in flashtool to fix this?

Did CSE flash, normal flash, TOT factory reset, wiping wifi's definitions.. Nothing seems to work :crying:
More info:
During the night, I removed the battery from the phone and booted my phone. After that Bluetooth would work, and Bluetooth adress would show up on "Hardware informations". Then, I turned off bluetooth and tried to put it back on. Bluetooth adress disappeared and my bluetooth would not turn on. Hope anyone helps..
How about your imei?

Also, forgot to say that, if I try to turn on wi-fi, if I connect my phone to my computer, computer will recognize I attached something and will start charging the phone, but I won't be able to transfer items to my phone since it won't appear anywhere on my pc..

I think I found a solution but I can't test it since I'm having problems connecting my phone to my PC ( another problem appeared..)
May I ask yo to install busybox and try this on adb?
adb shell
su
busybox iplink show wlan0
and see if it shows your real adress, if it does
busybox ifconfig wlan0 hw ether (adress)
busybox iplink show wlan0

I don't have my phone with me, sent it to repairing. Any news?
I'm having a very similar issue. Wifi and bluetooth won't turn on and cycle. On some reboots, Wifi will turn on but the phone will shut down shortly thereafter. I've tries several different ROM's and can fix the Wifi, but no the power not the shutting down.

I'm having the exact same problem but a bit worst. I can't even turn my phone on. Phone came back from repairing, guy couldn't fix it. Tried some rom's, many "fixes" from the internet, nothing. Seems like the only way to solve this will be by hardware..
exactly same problem with my g3 too
even i was using stock 30b firmware and after one week of usage it suddenly crashed and stuck in bootloop hence downgraded to lollipop and tried all roms,factory reset,different modems etc but still not fixed
waiting badly for an solution
I'm having pretty much the same problem, along with overheating and screen fading. I'm using stock Lollipop, never rooted. I've tried a factory reset and a new battery with no results.
Any solutions?
Guys I've sent my phone to a local repair shop and they said they took it to LG's official partner.. I've been waiting for a while and it doesn't look good.. A friend of mine bought a g3 recently. I suspect this problem comes from a corrupted or missing file. I'll ask him to help me on checking files if the local shop can't find a way to fix the phone. If everything fails, the only possible solution I see is a new main board or a new phone..
lg g3

what is the exact problem ur facing in ur phone.
my phone suddenly start to turning off by itself after few minutes of every startup.
And the phone doesn't recognize the sim cards too. Then I put it to flight mood and the problem solved. If I off the flight mood then again the phone turn off after few minutes.
I factory reset and also flash different roms. But nothing changed.
I can use phone without any issue with the flight mode on.
Anyone have a idea about the cause of this issue?

It's very likely that it might be the baseband or wifi driver, i had the same problem a while ago but i can't remember how i fixed it now. Probably flashing the original baseband. Maybe also by changing sim settings typing *#*#4636#*#* on phone application. Tell me what you see doing that.
One more question, did you mess with Nvram?
Actually I don't know about Nvram. I didn't mess with it intentionally. I don't know if something happened. Is there a way to check it?
Please help me. I don't know what to do exactly. What settings should I change by typing *#*#4636#*#* ? Thank you for trying to help me

No problem
Go into phone information change your current band settings to GSM/CDMA/LTE auto then restart, see if it works if it was already set to this option try changing to another setting. Btw you can't check nvram if you didn't touch it, don't worry

By changing band settings phone keeps turn on without airplane mood. It didn't turn off automatically. But No reception for both sims.

Its just a rubbish phone! I really regret buying this phone!!
Hi guys,
I've got a Mi Max 64gb, it was working ok and then it auto updated to MIUI 9 and now i get no signal. If I go into setting, it will show my sim name (three) but thats it. It has no signal and I thus can not make or take calls. The status bar at the top says no service.
I purchased the phone second hand and everything was working fine so did a blacklist check just in case and both IMEI come back clear. Also when I switch from fin network automatically to manual, it will find a few networks but will no connect.
Anyone know what can be wrong? Phone has locked bootloader fyi.

Ok so I got permission and unlocked the bootloader, installed TWRP and installed RESURRECTION REMIX 5.8.5 for hydrogen but its still showing no signal. Is there a way to check what can cause the problem as I've tried swapping sim trays (have a faulty one as spares).
Please show your holiday spirit and help me

I really have no idea what your problem might be, but the panacea in all weird cases, irrespective of the particular symptoms, seems to be to fastboot flash a official global stable rom with the Miflash tool.
Then you have hopefully a base "known state" to start from.
If you still have no signal, you might well have a hardware problem.

Hi,
I'm not any kind of expert at these kinds of (radio signal) problems today, though I do have a background in communications electronics construction (c.a. 1980's !)
If you did a complete format of everything before flashing the ROM, and it still doesn't work, I would guess you have a hardware problem.
Of course you want to double-check that your sim cards work in other phones.
I've had some rather weird problems caused by simcards.
You should even ask for a completely new simcard from some provider, and not put it into any other phone first.
How you could go about verifying that you truly have a hardware problem, without handing it over to a service center of some kind for testing, I really don't know.
Perhaps someone else has expertise in this area?
Otherwise, you just write it off as a loss, or sell it on Ebay for whatever you can get.
same with me. my phone not showing signal. the simcard is working before. it show no simcard after i flash twrp and supersu. the problem happen after restart phone. now i'm stuck searching this solution. help me.
Hello you guys!
I just received my lg g7 g710ulm. And when i turned on the phone i understood that im not lucky.. I need your helps! Please! Because i cant do it myself.
1. No signal. Don't search networks. Immediately getting error when trying to do it myself. "Preferred network mode" can't change due error and it showed "null". After reflashing it's now showing "22".
2. Don't see any wifi networks. But access point is working and other devices can see me.
2.1 I found that wifi going to work then i tried to use gps. After few seconds phone starting see wifi networks and connecting. If turn off wifi and turn on again phone don't see networks and you need to repeat procedure.
3. Looks like gps not working too.. But tried only in indoor.
I can't understand is it software or hardware issue. Maybe seller changed imei number and model by firmware and did it wrong? Antutu showing strange imei.
Can i to know somehow real model of phone? I can try to make logs and attached it here. Or maybe somebode can check imei, bands with octopus box? I dont know what to do
P.S. Bluetooth is working. Tried to send file and it was fine.
I can't return phone to shop because im living in different country But phone is amazing! And I loved lg. I had lg optimus one (was lost and back by good people), then lg optimus black(was burned in bonfire), lg g2(left in taxi), lg g6 (was lost) and finally lg g7. Yeah, looks like something wrong with me or these lg.. But i love it
Did you put in your SIM card first before you started...
I read you need to insert sim first but could be wrong.

Sure, i did it. Anyway don't search networks. But what carrier of sim card and numbers into sim card, phone can recognise.
Maybe i wrote not understandable? My english not first language. So asking. I will try to explain.
Thanks for your reply.
I uploaded a log file with errors but cant to write here link, because i need 10 messages
My G710ULM's GPS stopped working 2 days ago, still trying to find out what's the cause of it. Tried apps like GPS Status, GPS Locker, no avail that it isn't picking any satellites at all. Just searching for GPS location. Restarting the device haven't helped either. In settings I even excluded all apps in Power Saving Exclusions. In GPS Status app, resetted and downloaded the A-GPS, this should surely make the GPS work. No success.

Hello expert. I have an LG G7 ThinQ ULM phone. The problem of this phone is no phone waves signal, 3G, 4G. (a week ago that is good). I think that because the SIM and insert this SIM into other phones, this SIM still works very well. So can you show me how to fix it? Thank you very much!
Note: I was try as below but not success
Go to the Home screen;
Tap on the Phone app;
Switch to the Dial pad;
Type in (*#*#4636#*#*) and just wait – the phone should automatically redirect you to the Service mode;
Once you’ve entered this new mode, tap on Phone Information or Device Information;
Tap on Run Ping test;
Look for the button labeled as Turn Radio Off and select it;
Wait for the phone to restart;
Tap on reboot.

my imei wifi mac still exist and working but the problem still persist
update:
finally got my network working all you need is an original qcn backup or flash original modem_a,b partition with QFIL if imei shows null use this tutorial to change ur origin imei/MEID, im not gonna give full tutor or the file since no one answered me, good luck.

hi, i need help, same mistake, i dont get a solution
Hi guys, I bring a solution to this problem, I found this topic: https://forum.xda-developers.com/t/no-signal-after-crossflashing.4089281/, you understood better by reading yourselves, but basically I flashed the rom with lg up chip erase mode and my wifi/data started working again, I know this is not recommended under any circumstances but it worked for me.
However, be aware that ChipErase mode not only erases IMEI numbers, but also erases MAC addresses, EFS partition and others. In many countries if your device does not have an IMEI number or other identifiers, SIM networks cannot allow (my case in Brazil it worked) for you to register with them, i.e. in most cases your sim will not work on the phone and you will not have cell service. You may still have issues with WiFi networks as without MAC addresses your WiFi will be grayed out or the network may not allow you to connect. Also, be aware that in many countries around the world knowingly tampering with or changing your phone's IMEI numbers is against the law. IMEI number is how networks and ultimately law enforcement identify the device and its owner
