Help 4G no longer connects after 3.70 update.

[disastar]

After the recent update my 4G radio no longer connects with Sprint. When I turn 4G on the phone starts to connect to Sprint but then immediately disconnects. I noticed someone had a similar problem when they updated to a 3.30 ROM (see here: http://androidforums.com/evo-4g-all...ning-but-never-connects-after-rom-update.html).

I'm running a stock Evo with 3.70.

That's odd.. for mine, this update seems to have fixed the 4g lag ... Even the battery seems to last longer but that could be a placebo affect lol...

I have the 004 hardware, but that shouldn't matter!

Try a hard reset..

I posted a similar quirk here http://androidforums.com/2019141-post127.html. I show the 4G! icon in the status bar but when I go into the settings, it says disconnected.

Do you have hardware revision 0003? Your Evo is exhibiting the same behavior as mine.

I don't have any more 4G lag, but then again I can't actually connect to the network. I'm dead set against resetting my device and losing my texts. I'll reboot and see if that helps.

[EDIT] A reboot seemed to fix the 4G issue! And no lag (yet)...

Yep, 0003.

Don't forget to update your profile after the update of your radio.

Probably too late for you - but search sms backup in the Market - you'll find one free, good for sms, not mms unless paid.

Exactly - and PRL - update both of those after any update. It's just a good, safe policy.

I was having problems getting my 4G to remain connected. The status would change to Disconnected immediately after making a connection. I check almost everything. RSA Keys were fine. I thought it may have been the android-wifi-tether install so I removed it. Still no 4G. Just as I was about to turn in @ 3am, I realized the WIFI was enabled. After shutting that down - low and behold - 4G immediately connected. So glad I didn't go through the trouble of unrooting.

I've had that problem even before 3.7.

If I try to connect with Settings -> Wireless it scans, and quickly turns back off.

If I use the SwitchPro widget, it turns on everytime.

Now that I'm on 3.7, ths same is true...enabling 4G through the Settings is inneffective. I must use the SwitchPro 4G widget to turn on 4G, but 3.7 totally fixed my 4G lag issues.

I have not tried this with the Sense widget, as I use LauncerPro.

Are you connecting with Settings, or with a Widget?
