3G fix for Thunderbolt

**wakestrong** · 04-27-2011, 04:25 AM

LTE is back online, please follow steps at the bottom of this post to get everything back in order.
*If you are in a 4G area it is advisable to make sure you switch to eHRPD to avoid bad hand offs between 4G and 3G as well as allowing simultaneous voice without hiccups. I noticed my GPS was not working last night so it is possible eHRPD settings will affect your gps or it could have just been due to the network issues.

As most are aware both the LTE network and eHPRD are down (a special version of 3G for the Thunderbolt only). To get 3G data back you just need to change your settings back to the normal 3G network. Here are the steps:

Dial ##778# and hit send

A pop-up window named EPST will show up giving you 2 choices: View Mode and Edit Mode. Pick: Edit Mode.
Enter the Password: 000000
Go down to Modem Settings and pick “Rev A“
You’ll want to choose enable and click OK, hit the menu button and then press “Commit Modifications.”
Restart your phone and you should see 3G is working

last step (may not be required if you get 3G after restart)

dial *#*#4636#*#* go to phone info, then set preferred network type to CDMA auto (PRL) ---will stop phone from looking for LTE signal

I hope this helps anyone that is left in the dark by this outage.

If you are running a non-stock dialer or a rom that included a dialer it may prevent you from entering settings. Flash this zip to go back to stock dialer

For those that want instructions for after LTE is back on

These 2 steps will put you back on LTE and then put you back on the correct 3G for the Thunderbolt, when its back up.

dial *#*#4636#*#* to get LTE, go to phone info, set preferred network type to CDMA + LTE EvDo auto

Dial ##778# and hit send
A pop-up window named EPST will show up giving you 2 choices: View Mode and Edit Mode. Pick: Edit Mode.
Enter the Password: 000000
Go down to Modem Settings and pick “Rev A“
You’ll want to choose eHRPD and click OK, hit the menu button and then press “Commit Modifications.”

THANK YOU!! I thought it was just my phone. Comforting to know its an outage. Yeah I also noticed that it was the eHRPD network only, as I could get a strong 3g signal as you did above. Friggin amazing.

I REALLY feel sorry for people that don't know about these things. Their phone prolly barely works and eats battery like a fat kid in a candy store.

What a shame this is what it takes to get this phone functioning. I understand early adoption but this is amazingly ridiculous.

Nice work son.

Now the real question is... Why is this happening? What is so special that this only effects DA BOLTS?

**DJBeanPole** · 04-27-2011, 04:40 AM

Hmmm... dialing that ##787## does nothing. Just goes back to the dialer like nothing happened.

Maybe cuz he said ##778## not ##787## haha supposedly vzw was updating 4g network when it whlent down. Said our sd cards are not connecting to the network. 3 or 4 areas are all effected if you have a 4g phone.

It worked. Long nights at work cause me to do crazy things... like not read so well.

Because they use a special network for simultaneous voice and data (eHRPD) doing ##778# brings you back to plain old vanilla 3g that every other Verizon phone is on.

You gave me a much needed laugh at that tho, thx!! Just because it was such an utter fail. Its like someone saying go down the road, make a left then turn right at the red barn. Then they repeat it back, ok so go straight then make a right then turn left at the giant chicken? Lol

Thanks! This isnt the first time this has happened but certainly the longest. It happened on March 24th for a few hours.

This effects the bolt because it uses a special type of 3G that allows fast switching between 3G and 4G as well as simultaneous voice and data as mentioned. Not sure why the 4G went down but I think they are switching on LTE in new areas and this may have been the trigger.

**wakestrong** · 04-27-2011, 07:06 AM

Is anyone running the lightning rom and able to access EPST menu or ##778#?

**wakestrong** · 04-27-2011, 07:18 AM

These 2 steps will put you back on LTE and then put you back on the correct 3G for the Thunderbolt, when its back up.

dial *#*#4636#*#* to get LTE, set preferred network type to CDMA + LTE EvDo auto

Dial ##778# and hit send
A pop-up window named EPST will show up giving you 2 choices: View Mode and Edit Mode. Pick: Edit Mode.
Enter the Password: 000000
Go down to Modem Settings and pick “Rev A“
You’ll want to choose eHRPD and click OK, hit the menu button and then press “Commit Modifications.”

Other than looking at AC forums, how will we know when things are back to normal?

**Tortan** · 04-27-2011, 08:23 AM

Should make this a sticky until they get the problem fixed...
Thanks for the temporary solution.

**captsoto** · 04-27-2011, 08:34 AM

The good news in all this is that I am having the best battery life ever!!

Restart your phone and you should see 3G is working

Optional- to get it to stop looking for LTE, dial *#*#4636#*#* then set to CDMA auto (PRL)

I hope this helps anyone that is left in the dark by this outage.

so, assume i did this ##778# trick to get back to vanilla 3g.
but then LTE network is back up and running in a few hours.
would the PhoneInfo dialer code work to switch back to LTE? or do we need to go back into "##778#" menu and change something before editing settings to look for LTE again?

If you want to know when things are back up and dont mind your battery suffering then switch off eHRPD but leave the phone set to auto CDMA/LTE and you should see LTE come on when its back.

yea I thought about that...I won't be around any place to charge my phone today so I will just have to check AC off and on.

I believe you could just switch back to LTE to see if its on but if it is working then your gonna want to change your 3G settings back to eHRPD for sure.

Anyone refer to post 15 to do this.

**Rem** · 04-27-2011, 08:51 AM

Alright, I've tried ##778# at least a half-dozen times now and I keep getting sent back to the dialer. No pop-up or anything. Would running Tesla Coil have anything to do with this or am I overlooking something really simple?

Yes I have heard running AOSP contacts or certain dialers is causing trouble for people. If you can flash the stock dialer back on the phone or if you really need data you can go back to a rosie based rom with no dialer.
