I have a pair of HTC Incredible 2s, for the spouse unit and myself. The other one has a glitch, so I thought I'd switch phones to make life easier for the SU. Unfortunately, I mucked something up, because I have no signal.

Steps taken: Thinking I just want to do a brain transplant and move ROM, apps, settings, data & all, I ran a Nandroid backup on each phone. Swapped SD cards, and ran the restore from recovery. Got on to PagePlus and asked to switch the ESN/phone numbers, and that's when I saw it - no phone signal!!! How did this happen? How do I fix it? I'll be in big trouble if I don't get SU's phone back to working. o_O

I'm off to do a factory reset, but please post some help if anybody has suggestions. Thanks.

Edit - just tried factory reset, then restore nandroid, and no success. Still no signal.

All a factory reset does is wipe user-installed apps and data. Won't change anything in the ROM at all.

The Incredible 2 is the Droid Incredible 2, right, i.e. a CDMA handset? That's why you have to muck around with changing association between ESNs and phone numbers? So is there any difference at all between the 2 handsets? Because otherwise that should be equivalent to just installing a new ROM and swapping data, so if that stops one of them seeing the network you have to suspect that something else was different. They were running the same ROM to start with, or not?

The obvious fix: restore the original nandroid on her original phone - and if that doesn't get them working again, let us know! Otherwise that at least gets the phone working at some level, and we have more time to work out what was different between them (firmware/radio would be my guess - if they had different ROMs maybe the Radio Interface Layer in one of them was incompatible with the firmware in the other?).

Do note though that we don't have CDMA networks where I am, so that's just a semi-educated guess.
 
Thanks for the reply. Yes, that's the Droid Incredible 2, a CDMA set. It's GSM capable, but I don't need/use that. Actually, I forgot to mention, they are not on the same ROM. They run the same kernel, but not the same Android version. They aren't the same radio, either. :rolleyes: This would be the problem - running the nandroid restore does not get me a working radio. I really made a mess for myself.

I think my next step is going to be reloading the ROM fresh, and then just restoring all the apps & data as needed. I hope that works.

ETA - that didn't work. I bet trying to restore a nandroid on a phone with a different radio version fouled everything up. I'm going to try reflashing the radio.

ETA2 - if the two phones, the same model and same kernel, did have the same radio version, would the nandroid swap work?

Nandroids on CDMA sets ought to do exactly what you expect, backups of /boot, /system, and /data.

Radio firmware are in separate partitions. Those don't get corrupted unless flashing a rom or firmware intended for another model of phone, or attempting nandroid restores from dissimilar models. That doesn't seem to apply here.

What you don't see on a CDMA set is a sim card for access, except for LTE because that's a GSM technology, and you don't see user selectable APN data for CDMA access.

*Most* of that ought to be stored in separate, secure partitions as well.

Start with main settings, About - do you see an entry for Phone Identity?

You're looking for a list that ultimately shows your phone number, your name and several other identifying numbers for each handset.

Can you find that and does it look correct, that is, not corrupted and not transposed between the two phones?

I'm on Sprint unfortunately, so I don't know how to reprovision a Verizon phone, or even if you can. I know that Verizon doesn't include all of the tools that Sprint does, even in service menus.

Swapping nandroids from identical models ought to be safe, but typically you want to update your profile and PRL just to sure on a Sprint set.

I've not seen a profile update for Verizon, and for the PRL, they remove the settings update entry for it and have you dial a code (once considered a Verizon secret smdh) - http://www.verizonwireless.com/support/preferred-roaming-list-update-faqs/

Start there, it's the obvious stuff, let's see if anything pops out.

And please explain - how are you running different radio firmware and flashing that? Are you s-off and accessing a separate firmware flash or are you using RUUs?

No idea how the same kernel runs different Android versions unless you're on non-Sense roms. Any light you can shed there?
