How many of you have got this message? My guess is that you debranded your phone like I did.

Short Answer:
Look at your network settings, make sure you set to use only 2G, after and os update the phone reverts back to 2G&3G the cheeks thing....


Long Answer:
I decided to unbrand my phone about 2 months ago and the process went okay and was able to extend my battery life to almost 4 days with BT on 100% no WiFi.. It rejuvenated my love for the device to be honest. I was ready to throw it out the window before that.

Well I was bored on Friday and having issues with BeeJive (Again fix your damn software already) Menus were not showing up unless I moved the pearl after opening them etc.. small stuff but I wondered if it was my OS version. I decided to install the 247 and all went as planned untill about 4 hours latter I noticed my BB had a white screen the the terrifying words in black....

I was like WTF? Okay I'll take it as a glitch and reset. Another hour later it happened again! This was just too strange that it happened right after my upgrade to the 247 OS. So off to RIM's download site to get the proper OS for the Bold. Even after I used the proper OS version the same error kept happening. So now I started to question what I did wrong that might have caused this. After a lot of Google and putting all the stories together I came to this conclusion:

When you debrand your phone using the Engineering VSM like I did (So I could re-enable mass storage support after) it seems to really not like 3G anymore. What I did not realize is that when I did my OS upgrade and then downgrad the default phone settings take over for network settings and reverted me back to 3G&2G setting.

Once I set my phone back to use 2G only the problem went away.

If any one has anything to contribute I would like to hear from you. This is a touchy subject so please watch what you say here...

Interesting....I have a test bold that I use with the Engineering VSM and I haven't had that problem yet.

have you set it back to 3G or using it only on 2G? And are you on a 3 G network or in prox to on. I'm on Rogers if it matters at all

Caspan's solution of switching to 2G only worked for me.

hi,

I have the same problem as you. Have you found another solution to switch to "2g". Thank you for your help.

sorry error

Yes the latest OS release that you can find in the forums can give you the option to switch to 2G finally. I just need to reimage my phone back to the AT&T vendor ID and reinstall this OS i have been running with this modded vendor ID for a while now with no issues other then the 3G one which is not a problem to me because until they fix battery life ill never use it

Thank you for the reply but I wanted to know if the problem was solved for the 3g because I would like to 3g. sorry and thank you for your help.

I've had mine debranded with the engineering vsm for months now and have never had issues with 3G. No issues came from it at all actually. I'm on Rogers as well and 3G is living strong (except for the few times that Rogers was upgrading their network and caused 3G outages for everyone with a 3G device on their network =P ).
