Hi, It looks like the problem I have and which is location dependent but for me 2G works better than 3G. It seems that the Defy or CM10 is not working good in circumstances were it switches from one network technique to another. Reboots I have:
Reboot after switching automatically Wifi on with Easy Profiles. Effectively it then shuts down 2G/3G because Wifi is switched on.
At my work where we have indoor coverage with 2G antenna's. Much less reboots there if I put the phone on 2G only.
Some reboots I can't explain
I log my reboots with reboot logger from the play store. Pictures in Play store are not English but app is in English. Handy app!
I did play with several basebands but in the end the default baseband for my location worked best (3.4.2-145 Central Europe). More frequent reboots with others or the went info flightmode spontaneous.
No solution but you could play with the following settings:
Settings - In Wireless & Networks: More - Mobile neworks:
National data roaming
GSM//UMTS Network preference
Use only 2G networks
I did not find a combination which ends rebooting once in a while (a little less than one time a day on average).

[Q] DefyPlus Root successful(?) 2g-GPRS messed up-Please Help
@Mods: If this thread is not placed appropriately kind move/merge as appropriate. I did try to search for this peculiar problem but was not successful. Thank you.
Hello everyone,
Today I pulled the trigger and rooted my Defy Plus inspite of all the misgivings I had about my ability to carry it off successfully. And in hindsight my misgivings seem to be very justified.
The details of my device are:
Build # 4.5.1-134_DFP-231 & Android ver 2.3.6
SBF : 45.0.2310.MB526.AsiaRetail.en.03
The rooting guide I followed was as per http://forum.xda-developers.com/showthread.php?t=1542956
Recommended SBF's were downloaded and the method outlined followed
The long and short of it is:
*Most likely the rooting has been successful - How do I know? Well I installed a screenshot application from Google which needs a rooted device and it said my device is rooted and it worked successfully.
* The problem? The problem is, my primary objective to root the phone was to enable some call recording app or the other to work and if that did not work go for WIUI GB or ICS custom ROM which if I understand correctly is configured to allow call recording. My data usage is minimal at best restricted to some emails , work related browsing when I am away from my office. For this I use a 2g connection and that suffices. However after the rooting if the network is set for 2g the device does not list my service provider, even if I do a manual search for service provider. The very same phone works flawlessly if I opt for automatic network selection and it defaults to 3g which I do not want due to cost implications.
Now is there a way to resolve this issue without rooting a custom rom? Or do I need to flash a custom Rom that to extricate myself from this mess? Or do I need to go back to factory settings using SBF the device is shipped with?
Thanks in advance for any help
Success - Baseband reset for India
I was facing the same issue , after rooting my phone as indicated in my earlier post.
Subsequent to that I installed WIUI Rom - the stable version - from here, and used the inbuilt Baseband utility to reset baseband for India. Issue resolved.

Redmi 3s 2g network issue

Hi guys,
I have been facing really bad network issue for redmi 3s prime.. Basically there is alot of people facing this issue.. The problem is when network drop to 2g it will not revert back to 3g or 4g.. One of the facing issue sometimes when i drop it will go to IWLAN..
The workaround tips is we use 2 sims and sacrifice our sd card..which some of us dowan to..one other tip is to open gps and open google maps and let it run on background..which will drain our battery..
Some of the user said it is kernel issue, some rom issue and some said it is hardware issue..
I hope someone here will help to sort this problem..
Thanks and best regards..
There is no fix. Even with using Second SIM my phone (international model) kept dropping to 2G. It is also missing bands it claims to have. Only fix possible is if Xiaomi update their radio/modem drivers.

[HELP] Jio 4g. Horrible Connection.

The data connection on my phone goes away after every few mins. It's very unstable. Also all of a sudden there's no VOLTE. I've tried all APN methods. I was previously on Mokee, and the problem started. I went back to miui, the problem was solved for the evening. But it started again.
If anyone has any solution. Please help. I cant even call using 4gVoice app. I want a permanent solution .
All help is appreciated. Thanks in Advance!
It's jio's problem
Hopefully will get resolved till march

The sim worked fine on k6 power.
I solved it by going back to miui and then flashing mokee.
Yet, it's surprising that it happens so randomly.
Probably something to do with default APN.

Even I'm facing the same problem with my Redmi 3s prime. It happened with resurrection remix rom and I flashed miui again. But didn't work. I tried different methods, but none worked. One of my friend said that jio by default takes band 5 for better coverage which trades-off with connection speed(low internet speed). One way is, to switch the band from 5 to 3 or 40, which might improve speed. This can be done in something called "service mode" in the phone. He had LG G3 and used some secret key in phone dialler to access service mode. That key however didn't work with Redmi 3s prime. I'm still searching for one.

Thanks for the reply.
Though it's more about VOLTE, it's not working. Even if it does work with a certain rom, it goes away after a few reboots.
FYI: I don't have fluctuating connection anymore.
Though I really wish that there was a proper solution for VOLTE

But I do need volte.
For now I'm on the latest LOS, and everything is working fine for now.
A small tip to anyone reading this, never greenify any Qualcomm, and codeaurora service.
Bad news - u are not alone. Look at this: http://en.miui.com/thread-320293-1-1.html

Thanks for the reply.
Though, for now, the problem is solved.
I'm on the latest lineage OS, and have hardly faced signal drops. Volte too seems to be working fine now.
Miui seems to lock our bands at 800mhz which hinders the net speed, switching to 3g/2g in low network areas, to maximize network coverage.
That can be tackled, if you use an app called 'network signal guru' , to lock the bands to a higher frequency, for preference to Internet. Requires root though.
Hope that helps you.

anyone esle having issues with idea 4g

I'm having so many bugs in Idea 4g network. Is there anyone else. Is there any way to fix these.
Please help.
Same here bro. The same Idea sim works perfectly in other phones. But, in Zenfone Max Pro M1 there are problems like low data speed & signal loss intermittently.
More problem is when sim is in 2nd slot, signal gets lost totally..and to recover back the signal, a reboot is required.
I hope this software problem gets solved in next update.
