Hi,
I have a Lenovo vibe k6 note stock rom on Android 7.0.
Calls are working perfectly in Jio 4G (volte).
Recently I switched to Vodafone 4G (no volte).
When I try to place calls, the device is not falling back to 3G. I am unable to switch the network to 3G or 2G manually also. However 2G works when I change my primary data Sim.
I tried swapping the sim slots, toggling enhanced 4G services, restoring the device software, changing sim cards, replacing my sim card, the same problem persists.
I am using this sim with Lumia 640 XL LTE now. This issue is not present with other phones.
Any help would be appreciated.

Hey thanks for your reply.
I had the same issue even on stock rom once I unlocked my bootloader.
What can I do?

Hey Swarnakanti,
I had tried that and was of no use. I tried to reset the modem setting via fastboot, lost IMEI. Finally I had to reburn the IMEI and WiFi address with QFIL and restore the baseband. I've put the method for the same on a different thread, please share the thread with others too, there are a lot of people with the same issue.

Issue is solved, baseband has to be restored.
Please check out this thread if you run into any issues.

Hey all.
I own a Lenovo A6000 plus currenty running on MIUI7 5.1.1 ROM.
I've got a problem. 4G is not working but 3G and 2G are working fine.
When i choose 4g preference ,it always connects me to 3G network.
My sim is Airtel 4G enabled an was working fine ,but now I'm bit tensed about this issue.
It would be great if anyone could help me to solve this problem.
I've tried google but i failed. So you guys are hope.
Previously , i flashed NX rom but i've not tested mobile network on it.
*EDIT* Problem solved.
LTE started working automatically.
Listen Carefully.
The MIUI you are using....has a bug .... so called LTE_x.wiz-ok try to port rom again with new kernel

After MIUI , I've tried other roms just to check that 4g is working on other ROMS and now they all have same problem.
Can you tell me which kernel to flash with this?
LTE not working on Lenovo A6000
I have the same problem too please help me,the problem occured when I flashed the Oppos color OS 2.0 ROM and from then LTE is not working in any of the custom ROM nor I am able to boot into the download mode so that I could flash original firmware to fix the issue.

Thats the same situation I've faced. But don't worry.
I had activated 4g netpack when i was out .When I switched my mobile data on ,it shows 3g or H+ .But after some time ,it automatically catches 4G signal and everything worked perfectly.
Be patient and try this method,hope it works with you too.
Wish you luck.
i have also the same problem...

Check whether your IMEI is fine or not.
If its fine, then proceed to search for mobile networks. Before that, switch network mode to 4G.

Hey Guys I need help.
I was using Jio 4G for over an year .
Then i switched to Idea and Vodafone 4G .. For some day's they worked fine but afterwards my phone was not able to detect any 4G network . At first i thought to be network problem but when i inserted that same sim card in different mobile 4G signal showed up . I tried every operator sim card and not able to detect any 4G signal only 2G and 3G shows up . Only jio4g is working and that too very poor . I switched different roms and even flashed my Redmi 2 Prime using fastboot but nothing helped.
Please Help

Because of using different ROMs. There is a problem in Redmi2/prime phones that you need to re-flash IMEI numbers of your phone. For the solution you need to visit:- en.miui.com/thread-218200-1-1.html for proper solution

thanks it worked like a charm
3 weeks ago the 4g disappeared from my Redmi 3s after months of working fine on Virgin UK. I now have 2g, and the occasional call coming through. I've checked the APNs, I've done factory reset etc - nothing has worked. I've had 2 new SIMS and got the same problem. I tried a SIM from a different network today and still nothing. The phone was in the car when it suddenly went off so it hasn't been dropped or anything. What's going on??
Anyone..?

Have you tried using your SIM on another phone? Did 4g work on other phone? If it does, then maybe you should try to flash a fastboot ROM and see if it's fixed or not.

Yes the Sim worked in another phone. Are there any easy to follow guides for installing a flashboot rom? I'm not a technical whizz.

my service is also degraded, but i have lycamobile. i use to get H+ and now reciently i only get E. i tried flashing back to stock global and nothing fixed. im calling the company today and see.
I've given up and ordered a 4x
Hey guys I recently messed up my old logic board and had to get it replaced, the new one was a G930v and is a Verizon from what I can tell a d after getting the unlock code which it asks for when I put my sim card in then nothing happens and I get no mobile signal even after restart and the "Non verizon sim card" error is still there even after a reboot so I am a bit stuck here and unsure what to do next.
I checked the Imei and it is clean but I noticed the site recognized it as a G930T which was strange to me.
