I know the *#*#4636#*#* trick. So I selected 'Evdo Only' in 'Set preferred network type' menu from dialing *#*#4636#*#*. However, the change didn't stay after a reboot. The preferred network type went back to 'CDMA auto (PRL)' after rebooting. Is there a way for the phone to remember the change after reboot? Or I have to flash a customized PRL? Thanks

i9000m. still on stock rom, UGJG9
went and used the "*#*#4636#*#*" command
went into Phone Information
> Set preferred network type:
> Chose WCDMA only
> Pressed back touchpad to exit out of "phone info" menu
> Went back in to see it on GSM/CDMA auto (PRL)
Still in the Phone info menu
looked at network type: UMTS
the original intent was to get the handset to stay on 2G to conserve power
WCDMA only means that your Phone will only use UMTS...?
Same here on the vibrant. Seem to be a problem on all galaxy phones
Don't press "back", after you make the change press "Home" and the change will be saved.
I just verified this on my captivate flipping back and forth between "WCDMA preferred" and "GSM/CDMA auto"

Why don't you try other settings? Such as gsm auto prl and wcdma only? Oh and did you restart your phone after??
When I flashed my phone with Bell's 3 button firmware I got the same issue. Now I'm back with my aussie stock firmware and all is well.
Try switching the rom.

Hey to get WCDMA only you can just go to Settings>Wireless and Network>Mobile Networks. It should be changed to WCDMA only now if you go back to testing .
I, however, would like to change to WCDMA preferred in testing, but I'm having the same problem as it just keeps switching back to GSM/CDMA auto (PRL)... Does anyone know a fix for this?

Hi Everyone,
I'm looking for some help.
I'm wanting to set my network to "WCMDA Preferred" under *#*#4636#*#*. I am running Ramad's Stock Deodexed 2.3.3 JVH with CF-Root v3.2.
I had it set to "WCDMA Preferred" a few days ago after the Vodafone Shop in N.Z set it to "WCMDA Preferred" which made my 3G Connection much quicker.
I had to fix a problem and had to re-flash 2.3.3 JVH with CF-Root and when i went into *#*#4636#*#* it was already set to "WCDMA Preferred" but once I exited, it reverted back to "GSM/CDMA, auto (PRL)" and I can't change it back to "WCDMA Preferred".
The Vodafone Shop told me I need to select WCDMA Only under the Wireless & Network>Mobile Networks>Network Mode, but then I can only select WCDMA under Radio Bands.
Does anyone know how I can fix this, would it be worth me reflashing 2.3.3?
Cheers,
Don't you have a "WCDMA Only" option in "Network Mode" ? Select that...

If I select that I don't get as good reception as when set to the "GSM/CDMA" auto mode.
Ok, I would really love to set my phone to GSM auto prl because the 3g signal in my area sucks.
But, here's my problem. Whenever I enter *#*#INFO#*#* and select GSM auto prl, it says "Unknown" instead, and after reboot reverts to WCDMA/GSM auto.
I'm currently running Mosaic VI, TalonDev .4.4.8, UGJK4 modem.
Any ideas?

I am running the AOKP-targa-milestone-4 mod of ICS and i set my phone mode to just cdma because data kept dropping. Now 3g and wifi are completely stable and i would like to change the mode back to cdma/lte but my bionic wont let me, i press on the cdma/lte mode and it reverts back to just cdma. Any i can do to re enable 4g?
Go to the dialer, enter *#*#4636*#*# then tap "Phone Information" and then under "Set Preferred Network Type" and you should be able to find an option that looks like either
1. CDMA/LTE Auto (PRL)
2. GSM/CDMA Auto (PRL)
