I can confirm that it doesn't work with AOSP contacts on this rom. I flashed back to stock contacts and did get the menu, so it isn't the rom. Mine was already set to Rev A.

So far this morning I've gone between 3G and nothing. This is with the CDMA+LTE/Evdo Auto setting and the leaked radio.

Enabled? Did you activate your phone in a 3G only area? If so I think this would explain why your phone was on this setting

Is there like a zip somewhere so I can flash stock contacts?

Any chance someone please could upload the stock contacts for a cm7 user with no wifi around? I would download bamf but at 1x speeds that would take forever.

Thanks for this info. It worked for me.

I wonder when it went down exactly, because I was navigating and chatting on the phone at around 10:30-11 last night and all was well.

Oh well. I'm sure they will have it fixed soon.

I wonder when the first "This is Ridiculous, I paid for this device and i expect........." thread is gonna start :)

No, it was activated in a 4G area. I work in a 4G area and the phone was purchased in a 4G area. I live in an area with no 4G. With the stock radio I had problems with the 4G/3G handoff and enabled Rev A based on a prior thread. However, that was at least one (and possibly two) roms ago. I'm not sure how that setting "stuck" through those changes.

Flashing a ROM will not change these settings unless it has other things attached like a kernel and radio.

I'm using Tesla Coil with the leaked radios. I had the stock dialer to begin with but went ahead and flashed the .zip from original post and still no dice. ##778# and right back to the dialer like nothing happened....

Outstanding especially the info in bold on committing changes through menu! Other sources left out that important piece and I was wondering why the changes weren't sticking. Leaked stock rom and radio unstuck from 1x and on evdo rev a . ;)

Like others, I'm not getting to the menu when I use ##778#. I'm running VirusRom, which uses stock contacts, and have tried it with both stock and leaked radios to no avail.

Rather than just taking me back to the menu, I get a FC error for EPST (com.google.android.epst). Lame.

    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 necessary)

    dial *#*#4636#*#* go to phone info, then set preferred network type to CDMA auto (PRL)

    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.”

    By default we are setup for the eHPRD 3G network on the Thunderbolt because it allows faster switching between 4G and 3G. Since both network features are down you have to switch your settings to the 3G network used by all other Verizon phones.

    yea but in your instructions you said select eHPRD, which is already selected.

    Do all this steps.
    1. I dial ##778#
    2.tap edit mode
    3.password. is 000000
    4.tap on modem settings
    5.tap Rev.A
    6.Tap on enable
    7.Tap on the menu on your phone
    8.Tap on Commit modifications
    And after you do that your phone should reboot and you should have 3g

    THEN AFTER THE REBOOT

    Dial *#*#4636#*#*
    Okay now scroll to the bottom. the box should say "LTE MODE" I have no 4G service in my area. So I only got. 1x. I changed my radio settings to auto PRL. Its 3G only saves battery. And for. 3G and LTE
    Is (CDMA+LTE/EvDo) then after just press the home button then. 1x will disappear then 3G will appear :) there you go. Ladies and gentlemen
    Your favorite android :)

    Question.....I live in NW Indiana, not a LTE area, Chicago is about 45 miles away from me, which has LTE. However I have had NO 3G since sometime Tues/Wed. Did this "fix" and now have 3G.

    Why would this affect me if not in a LTE area? Or is it coming?

    You were on the thunderbolt's 3G network, which went down when the LTE went down. Currently our phone is the only one to use this type of 3G which allows simultaneous voice and data (this was a selling point for the Bolt).
