evdo switching to 1x

[crazycracker]

I'm not sure if this happens on verizons rom or not because i always flash all my xv6800s to DCDs newest rom and im using the newest radio and the newest bootloader and also i built the kitchen with the verizon cab and mms cab built in as oems and mms, phone calls, gps, internet, data connections, and everything works perfect except one thing

I noticed that my phone switches to 1x whenever i make a call even if i set the phone to use evdo only and i know i have a good enough evdo signal because other phones stay on evdo fine and my laptops have mini-pcie EVDO rev a cards and they are set to EVDO only and they work fine

probally doesnt matter but my laptops all have mini-pcie novatel EVDO Rev-a cards on sprint and my cell phones use verizon and they all stay on evdo fine and the xv6800s stays on EVDO during data connections its just whenever i make a call or send/recieve sms messages it switches to 1x

That's completely normal. Voice is always handled by the 1xRTT (1X) network. EvDO only handles the data component. Nothing wrong with what you're seeing.

:( The Telecom New Zealand phones are the same where Telecom's WM5 seem to use EvDO alright but with all the new ROMs data always revert back to 1X

I think you need to do some reading on CDMA technology and how it works.

1xRTT = Voice/SMS
EVDO Rev 0/A = Data/MMS

It's always been like that, always will (until LTE is rolled out).

I mean, it's right in the name for pete's sake....EVDO...Evolution DATA ONLY.

IU have the same problem, I have sent it in to telecoms repair agent and have told them the evdo isn't working, I am waiting to find out what the will do when they find my phone has wm 6.1 on it.

If you get no joy out of telecom the WM5 ROM has been uploaded to PPCGEEKS but you will also need to rollback you Radio as that file doesn't have the radio only the ROM

Understood but EVDO will alway revert back to 1X if it can not get a steady connection, that appears to be what is happening. I'm talking about Data connections (I am only speaking about myself)
