Cannot Make Calls At All - One (M7) Q&A, Help & Troubleshooting

I am currently on Insertcoin 4.0.4 and cannot make calls. When I try to make a call, it would just say "call ended" immediately without ringing. I also cannot receive calls. I changed rom to PA CM11 Beta 4 and the same problem persists. No matter what I do, I can't make calls. I started to believe it was the radio, so I just flashed the T-Mobile US 4A.14.3250.15_10.34.1150.02L from the Radio dump list and still cannot make calls. I am S-off with the latest firmware and I noticed that this happened when all the roms in the forums changed from M7ul to M7lte. Is there a solution to this? I have tried wiping the data of the dialer and even installing a fresh rom with a full wipe. After a clean install, I would be able to make a few phonecalls before it starts doing the same thing again.
Thanks

[Q] SGS issue force close on receive call

Hello
I just installed Darky's 5.2 ROM over my stock 2.1-update1 and everything works fine, but whenever I receive a call something (dialer?) gets a force close and the call is rejected together with a temp. loss of signal.
Then everything is back to normal...
Any steps I'd take? I'm pretty new to this.
have the exact same problem... can dial out no problem but only receiving calls. so thinking about whether I should flash another rom until this is fixed.....
I was wondering could I just do a factory reset and then flash the rom over again? Do I have to disable the voodo lagfix before? Not too sure how this works heh.
I don't have this problem. But whenever i am in the game "flick kick football," I get some random hangs, and is forced to close. I suspect that happens when I get incoming calls. Anyway to confirm this?

I have the same problem. I recived a call, something force closed, the signal dropped and i lost the operator. I had similar problems with bluetooth and file manager before on this ROM, but I re-flashed it and everything worked again.
no problem here with Darky's 5.2 ROM and the Clean Guide Instruction, i just received a call without any problems
I used the easy guide and did not clean anything or do a factory reset, I just followed it like a dumbo. I came from 2.1-update1 stock JM5 kernel with a ton of apps installed, if that helps.
hey I think I found a solution to this. I went to recovery mode, wiped cache, wiped dalvik, did a factory reset and voila, receiving calls works without force closing.
phew.. was about to download another rom. anyhow, hope that works for you Jule!
still a few problems with the ROM that i encountered:
- my AT&T home button is not working.... not to sure whether there will ever be a fix for it
- media volume, even set to max, is not working when playing movies and youtube.

[Q] Please HELP unable to make calls- No sound in-out after upgrading to JB LT4

Hi all,
Last week I upgraded my Note to new LT4 rom.(s). Couple of days later, my Note was unable to make calls. When I try to make call or receive a call, there is no sound neither from earpiece nor from the speaker. If I reboot the phone I sometimes be able to make some calls with a great noise on the background then it stops.
I re-flashed the rom and flashed other roms even re-flashed LZS roms with all clean install even finally formatted the internal sd card . No change.
Since I can make one-two calls after each reboot I still think it may be a software issue rather than hardware.
All other functions including cell reception, 3G, internet, wireless all working very well but cannot use it to make phone calls.
If you have any suggestions I appriciate.
Best Regards
Update - I installed the stocked LZS Rom but the problem still continues.

have you checked that your IMEI is the correct one? maybe it got corrupted...If that is the issue, should be solved by restoring your EFS backup .

No, I haven't checked. But I don't know my previous IMEI . How am I supposed to know if changed or not? I haven't backed it up. How to restore to original status?
Thanks

Below the battery you have the original IMEI number...if it is changed, then that is the issue. If you don't have a backup of your EFS, I am not sure but you can try to flash the stock rom by selecting EFS in ODIN PC. That is stuff is quite delicate, so I would recommend you to ask Dr. Ketan that he is more familiar with it.
But again, make sure that your imei is fine first. If that is not, then might be a hardware issue..
Thank you for your kind suggestions. I checked and it looks O.K. there is no change on IMEI. Actually I can receive SMS and 3G is working very well, my phone rings if someone calls but cannot talk.
Problem continues
Hi There,
The problem still hasn't been solved. Somehow all is going fine and suddenly re-occures. Has anybody come up with same problem and found a solution? Please share.
ı am on xlt6 Rom with Philz kernel

CM11 no phone service but data works

I just flashed the CM11 rom from this thread: http://forum.xda-developers.com/showthread.php?t=2518124
I have 3g and LTE service depending on where I am with working data but I cannot make or receive phone calls or test messages. Data works fine. I have tried the latest and the oldest radio, no change. Even if I restore back to my stock ROM I still have no phone service but data will work. I have also tried to flash the CM11 rom a few times. I am on the 11/19 nightly. Im not sure what else to try.
I was looking through some setting and found my MIN number is set to 8471110111...Im guessing I have to get the correct number from sprint and figure out a way to change it to the correct number?

No network in phone...help needed

i unlocked my sprint htc m8 by changing the cid to 11111111. after that network appeared in the phone, but i could only make outgoing calls, no incoming calls were shown on the phone, so i decided to root the phone thinking maybe it would solve the issue, so first i tried installing the ARHD rom, which was not made for sprint, so then i tried the nusenseven rom, after installing the rom there was no network in the phone , it was always searching for network , and i couldn't even search network manually as those options were greyed as it was only searching for network, but i was able to receive incoming calls on the phone without network , but coudn't make outgoing calls due to no network, same issue happened in the skydragon rom,
anybody help me out to solve the issue please.
Have you tried ##72786# or ##786#(if you have msl code)
And press reset at top right
I am having the same or similar issue. Since installing skydragon I have a constant message in my notifications saying that it's "unable to establish a wireless data connection". No problem with wifi.

after pressing the above codes nothing appeared, where to press reset
Sounds like your missing EPST options, that's odd, can you flash Stock Rooted ROM and do that code.
If you flashed a rom that was not Sprint compatible (ARHD is not as far as I know) you messed up the partitions and the only way I know of to fix it is to RUU and start fresh.
ok, i again started again with stock and then a compatible rom with htc m8 sprint that is skydragon, still the phone has no network but i'm able to receive call, i don't know how.
in stock rom i was getting network with no incoming calls.

Did you RUU?
If not it's not going to fix you issue.
