3G confusingly goes on/off - One (M7) Q&A, Help & Troubleshooting

Hi all, in the beginning I thought it's a problem with my network/SIM card. For that reason I tried a SIM card from another carrier, but problem persists..
So, suddenly my phone would only lock on GPRS/EDGE and denied to go on HSDPA/3G/4G. Completely out of context at that time I thought to dirty flash a new nightly of the Carbon ROM that I had already downloaded, and the problem was solved!!! Booted in android, and boom connected to 4G..
It happened again during the following days, and every time a dirty flash of the next nightly would fix the issue. Without a logical explanation for my understandings, but it just fixed the problem.
Now, since yesterday, it is not recovering with the above technique so it's time to seek further into the issue! With your help of course

Just in case, did you checked your ''preferred network type'' by dialing *#*#4636#*#* ? It should be set to ''GSM/WCDMA/LTE AUTO''

Actually no, I was not aware of this setting.. WCDMA preferred is selected, and the option you suggested does not exist. You can see the screenshots for the options..

[Q] [CM11] sms not working

Hi all! I have a droid 4. i just flashed it with CM10.2.1 and then updated to CM11. in both version sms is not working. I type a new text and it fails: i get the red triangle and message not sent.
I looked around and I found it's a common issue and if you remove "voice+" sending sms is available again. I removed "voice+" going to system>app>voiceplus.apk and deleting it as i saw in a thread and reboted, many times. still not working.
then I also went to the *#*#4636#*#* menu and checked the SMSC. I tried both the +39 and the 079193 version but still nothing.
I have to add I'm using the phone in italy over a GSM network. Phone calls and data network (3G) works perfectly!
How can I fix this? CM11 is a stable on this phone, strange to have such a big problem!
Thank you for help!

Installing the patch twice uninstalls it.
Install it again and then reboot.
If you upgrade the ROM at any point in the future you don't need to install the patch just reboot again.
So, first reboot after a ROM upgrade will leave you with no GSM signal but another reboot will bring it back.

Scott

I did it and in the 4636 menu I have GSM but still does not get signal...
Have you tried using an alternative SMS App? Hangouts maybe?
So I managed to solve the problem. This is the way:
-deleted rom slot 1.
-recreated a partition in rom slot 1
-wiped everything in slot 1
-flashed cm 10.2.1
-flashed gsm patch
-booted
-flashed gapps
Now everything is fine!

this sound like the start of the problem i have. it started with the signal dropping and a reboot fixed it. after a few days i lost all signal and iv never been able to get it back. iv tried changing baseband gone back to stock changed the RIL and nothing has worked. ive pretty much given up on finding a fix.
i am seeing this problem pop up more and more i really hope someone is able to find a fix.
similar problem here. it happens if I leave wifi area without switching wifi off. Effect: high battery drain, sporadically network "locks" and broken sync (reddish network symbol in quick settings). I'm on cm 11 actual nightly,. tried other roms without success.
Fiddling with some settings, but only way to get a temporary fix: reboot to recovery, wipe cache an dalvik, reboot. Afterwards got sync and network (symbol white).
We can only guess at what the issue is, without logs

[Q] Xperia Z c6603 Sim card not detecting problem

Hello Friends,
I am sorry to create this thread if already a discussion going on under the same topic( I am that much frustrated as well as desperate). I updated my set to 10.5.1.A.0.292 few weeks back & when it reboot I get a popup window saying nfc firmware update error 000004 which is present till the date. Then it starts a new issue like loosing the signal and reinserting the sim card rectifies the issues at first. Few days back it completely lost the signal & a sign appeared on top right corner like a red "X' mark with sim card.I tried to reinsert the sim and when I does the set shows 'sim card inserted , restarting' but after reboot again no signal, when i removes the sim again it popup as 'sim card removed, restarting'.
I tried many other sim cards. Result is same though all are working in other phone. I tried every thing starting from factory reset to flashing using PCC as well as Flash tool but still the problem persist. When I flashed CM 11 and searched the set shows all the available networks ( Though no signal was showing in status bar) but fails to register in any of them. Any idea what happened to my set and is it curable. Please help it doesn't have warranty.

does it work for CM11? maybe there is something wrong with your hardware, check what does it display on baseband, maybe try a reflash once again.

Hello Zennis thanks for the reply. I tinstalled cm 11 on it and then also there is no signal bar in the status bar but under mobile operator option i was able to check the network and all the available network were showing there but when i tried to connect my service provider it failed. I dont think there is a hardware problem coz i use it that much careful and hardly 5 minutes before this issue i attended a call.
Looking forward for your valuable reply.
I think its a baseband problem.... I previously faced problem like no signal,no imei,no wifi, etc...then i flashed different version of stock .ftf
And my problem was solved.

Hi puneet its sad to know that you too are in same situation. As I said in my post the unit was functioning for about several weeks and suddenly it fell into no network state again and this time all my trials went vain. I just sold that unit at a cheaper price to a mobile repairing shop. i dont know what they have done with it. In my opinion dont waste your energy for xperia crap.
Thank you & sorry that i cant help you.

Hi everybody (and sorry in advance for my poor english) !
I am having exactly the same problem as the OP. To explain the situation in a nutshell:
I have the SM-G800F, for about a month. It worked fine, until I moved to the other end of France (it probably has nothing to do, though). Passing on the highway, "Emergency calls only" showed up while I was looking at my emails. The problem is that things never got back to normal.
The situation :
As I said, the same as the OP. When I turn on my phone or I go out of airplane mode, my phone tries to connect to 2G, then 4G / H+. The process takes a few seconds, then any indicator (left of network "bars") disappears, and I can't issue or receive calls, nor use data.
But if I force "2G only", everything works just fine.
I was using a rooted 5.1.1.. In the meantime, I tried several suggestions found here or elsewhere:
-Turn off the phone and on again : Nothing
-Enable / Disable flight mode: Nothing
-Remove / Replace the SIM card: Nothing
-Putting the sim in another phone: everything works just fine, so the problem may not be a faulty sim card
-Wipe Data / Cache Data then use Odin to reinstall a stock 5.1.1 rom (I'm really a noob to find the right words, sorry in advance, but my phone says, under the "version number" field , LMY47X .G800FXXU1BPC4 and the ROM I used is named : -G800FXXU1AOG2_G800FOXX1AOG1_G800FXXU1AOG2_HOME.tar.md5 filename
Manual carrier selection : Nothing
-Turn on Data Roaming : Nothing
-Checker my APN : Everything seems just fine
I can't tell for sure but I do not think it is related to my home. My problem began on the road and took the rest of the trip (2h/3h), and even around in the city, it remains. Moreover, my backup phone and the other people on the same network as me (Orange) don't encounter this problem.
So, I'm a little bit confused and a bit worried because of Knox (0x1: /). If you have opinions, advice, guidance, thank you very much in advance!

Hi !
Not yet ... I have another phone now but i still try now and then to fix my S5 mini.
So far, nothing worked. Some tech guy told me it was a common issue with that phone's antenna. Also read that from several forums.
Still, i read that some users were able to fix similar looking issues by flashing the modem file with Odin. I'm a bit n00b but i guess i'll give it a try.
Any success on your side ?
You can try searching for your carrier manually and choosing it.

Thanks, but i already tried that many many times. My S5 Mini just displays "Network XXX unavailable" (or its nearest equivalent in French)
Did any of you manage to fix that by flashing your modem file with Odin ?
I've tried additional stuff but nothing seems to work. Back to stock Marshmallow. Still loosing radio signal whenever I enable 3/4G.
Maybe the bottomline is "hardware failure" but who knows...
Thx everyone!

Have you tried a deep reset? If it does not works, try a custom ROM...
Hi !
Thanks for your reply,
I did try "Factory Reset" and "Wipe Cache" while in the Recovery Menu (Home+Power+Vol Up if I remember well). Is that what you were refering to ?
But I think I didn't try flashing a custom rom. Could you recommend one ?

Yes I was meaning this. For a custom ROM i can recommend One of the latest with NOUGAT like Lineage OS 14.1

Hi,
I installed Lineage OS 14.1, it's great but the same problem keeps happening. Everything works just fine in 2G, but whenever I enable 3G or 4G, my phone looses radio siglal and switches to "Emergency calls only" after a few seconds.
Any other thoughts ?
Thx !
As a side question, would you think of any way to rule out/confirm the possibility of HW failure ?
Thanks again !
Did anyone found solution for this?
Hi,
I've got the same problem. Tried to flash with Lineage 13.0, then 14.1 and still the same problem.
Anyone help?
Flash the last modem/baseband, did yoy try *#*#4636#*#* ? You can manually select wcdma only(3g) or lte only(4g) (sorry for my bad english)
still not working
When I choose 3G/2G auto connect from 1 line ti go to 4 signal.. so no LTE /4G for now..

No Service Until Reboot

I get no service often and it does not go away until i reboot my phone. I have tried the following but failed.
1) Unlocked bootloader and installed CynogenMod 13.
2) Installed Team Bliss Firmware
3) Updated Radio and Bootloader to S4UTL 49
4) tried the 4636 code and manually set the preferred network to LTE/GSM Auto and GSM Auto too.
5) Tried Different Sim Jack.
6) Tried different network sims.
7) Now i am back on stock rom 49 but issue persist.
Please provide me a solution or atleast give me an idea how do i make my system to reboot on no service automatically so that i dont miss important calls.
I believe this is a known issue with poor service areas.
Sadly I do not know a solution either.
When i use my sim in other phone it works fine and i have no such issues.just with driod turbo i am having this issue.
I, too, had this issue, but only when I went to the Brazilian MM ROM. I did not have that issue on stock LP (unlocked bootloader, Xposed).
the only thing different I did to help resolve it was I went into the developer options and set the "Aggressive to Cellular handover" to on. You may also want to see if "Cellular data always on" works as well. However, when I just checked this setting, it was set to off (but I had flipped it to on about a week ago, and I'm wondering if it defaults to off on reboot).
so see if one/both of those options works.
I switched both on let's see what happens.
try also to see if this happens after a phone call. I'm wondering if the lack of VoLTE is causing the issue. could some issue where the device thinks that there is a call connection when really not???
Same issue with me, When I Google I found this is common with Motorola mobiles but found no solution yet, Please help if any one have resolved it yet
