You have your phone on proper network switch? (just incase you overlooked :angel
I have same issue with BSNL, it just doesnt work on 2G mode, no network but my airtel sim works without issues on 3G n 2G.
I am on CM9 GB kernel + SOC Defy.

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.
