[CDMA] Can't Activate Phone

So I recently attempted to flash CM10 to my phone and I think it royally screwed everything up. After messing around with JB for a bit (no working data) I decided to flash back to stock and stay there for a bit. Well, once the flashing was done, I attempted to activate my phone, and it kept failing. Tried re-flashing just to be safe, and it failed again.
I then tried restoring from a nandroid I had, hoping it would restore service like it normally does. But it didn't. It showed my phone as unactivated. I was still unable to activate my phone. D:
I looked in About Phone > Status and my MDN and MIN were screwed up. My phone number displayed as "000-000-5472" and the MIN was all 0's. Any help or ideas would be much appreciated.

Might Help
I also did the same thing a while back when i tried out the UK Firmware and when i flashed back with the stock Verizon firmware it erased my phone number and a lot of other stuff but here is a link from a while back explaining how to change your phone number back it worked for me but i never got my 3G working right some info will be different I have the C Spire R800x.

Good Luck

U need to flash the baseband to stock baseband as well as the firmware, and re activate your phone
Happen to me when i flash new baseband and kernel to my R800x
Can't activate since the prl was not loaded properly and i can't get through activation process (ics glitch)
End up flashing to stock, re-inject and activate. Then restore the new ROM via nandroid. This way the phone stay in activated state.

When you flash a baseband before installing a rom, activate your phone on the stock firmware first, then install the rom. Same happened to me but I couldn't see the numberpad.

restoring efs with nvtools/qpst

hi guys, i flashed the lte modem on my phone and it seems that its wiped out my efs folders, ive been trying to restore my efs folder with nvtools and qpst, neither seems to work since somehow dm mode is not responding to them
any solns? ty in advance for any help
a couple of things:
ive already odin'd back to stock, no luck on restoring efs(perhaps im doing something wrong?) i dialed *#7284# and put it into the RNDIS+DM+MODEM mode, nvtools says phone failed to answer while QPST says that comm7(the samsung serial port) is not a phone
its pretty had to do this since the phone is rebooting itself every other minute

Questions and help issues go in Q&A
Thread moved
Thanks

Been there, sucks. For me to get out of the constant restarts I had to flash the lte modem again. Flash stock (odin) flashed cwm (odin), put the modem on my external sd card and flashed that.At least that way I could work on it a little. And below is basically what I did to finally get it to work. Hard to say all my steps as I was trying everything.
Well I dont really know how I got mine back to life, tried all the standard stuff from the threads,got my imei back but had no network,network type,service nothing helped. last resort I said whatever ill try anything now. Came across this
http://galaxynote2root.com/galaxy-n...3g4g-aws-bands-on-att-galaxy-note-2-sgh-i317/
whatever it did it restored everything (cold see carrier,network,etc)but corrupted imei, next i followed this guide
http://forum.xda-developers.com/showthread.php?t=1804117
If you need this is a complete no imei nv backup I used before flashing my imei with the generator
http://db.tt/4hunZ7qy
used the imei generator, then the writer (link on post does not work for the imei generator,so found it here
http://d-h.st/vVV
Wrote my imei back and presto, back in action. Fully functional again, including 4G
Like I said this was a last resort, but worked

got it fixed on friday, was so tired that i went to sleep
basically i followed someone's post on the forum(forgot name) and flashed the tmo modem, since the mct one always gave me the bootloop, then i enabled DM mode and finally got nv tools/qpst to recognize my phone, it appears that the issue was that the drivers does not recognize the new modems..
anyway, once i was done restoring nv, i flashed the tmo lte modem and paranoid android
now i have my imei back and i can use lte
although my bluetooth address still says unknown..not sure if normal

My bluetooth also says unavailable, I would think if you are not hooked up to bluetooth then it should say unavailable. Im to scared to flash the tmo lte modem again...

[Q] No service on phone

So I posted this on the general android help section but didn't get much help so I'll post here too:
Hi everyone, I have an LG Optimus G (F180K) and I've been using it fine for the last couple years and most recently under the V30D firmware which is KitKat 4.4.2. I've flashed CM11 and MIUI on it previously but restored it to the stock rom several months ago and have stuck with it since. About a week ago I flashed MIUI again as it seemed there were new builds avaliable. The installation went fine but when the phone booted up I realized I didn't have any service and my service provider was not being recognized as it just said "No service". It did show there was a SIM card inside though. So using CWM backup I restored back to my original stock rom and realized there was still no service so I did a clean factory reset. That didn't fix the problem so I tried updating the phone with the kdz files straight from LG's servers which still didn't fix the problem. I checked my IMEI which was not broken and the phone number of my SIM card is recognized but it just always "No service". I tried reverting back to stock rom and factory reset multiple times the past week but it still won't work. Any help? Thanks
So basically I have a rooted F180K that won't get service despite a clean IMEI and reverting back to stock rom.

i have the same problem but in a 977, i did it all but keeps the same searching for network

Try this with terminal emulation app or adb shell. (You must be rooted!)
If you have problem with sqlite3 command you can download and install with Play Store.
Code:
su
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE global SET value = '10' WHERE name = 'preferred_network_mode';"
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE global SET value = '0' WHERE name = 'subscription_mode';"

i did it, but i only get gsm network, i can't get 3g, i restore my efs bkup, my modem but keep the same, only gsm
--------------------------------
Flash my carrier kdz, but keep the same, i dont know what's wrong, only gsm, thas all i can get

(D852)Cannot connect to cellular network.

hello,
I have installed a custom rom onto my lg g3 d852 model. But after many failed attempts to correct it, my phone will not stay conected to my mobile network. My phone is now running MM 6.0 on the koodo network. I believe that this problem may have started because of a setting I may have changed in the hidden menu.
Ive tried:
-downgrading back to LP
-Switching sim cards
-updating firmware
-checked the imei (still says its there)
Any help is greatly appreciated.
EDIT: I have found a temporary solution. I switched to HSPA only in network options, this got my phone connected back to the network at least for now. I would like to have access to all frequencies. Any suggestions?

Bump...

Which custom ROM did you install, and does the problem persist after a factory reset? If it's merely a setting you changed the restet will put it back to default. If it's a modem setting you changed in the hidden menu, a clean flash of the ROM will get you back to where you started.

I made a mistake, the rom is a stock rom MM of Koodo/Telus provider that I downloaded off of xda... I can link to the rom if necessary. I have factory reset several times and tried Fulmics LP and MM and this version I'm currently using getting the same results.

If I were in your shoes, I'd do one of two things. First, I'd try the nand back I made when I got the phone, before I'd flashed anything. If you don't have a good back up, one that includes the efs, modem and bootloader, then you need to revert to stock using the factory kdz image. There's a tutorial here http://forum.xda-developers.com/showthread.php?t=2785089

I shall give this tutorial a try. Thanks.

Verizon HTC 10 will no longer work on Verizon after flashing

I flashed the the newest firmware, then flashed the Pefume 2.51.617.32 rom, and now the cell portion will not work. It will pick up a signal if I reboot, or sometimes toggle airplane mode. It will show 4g, but then it just goes back to the line over the bars. The sim card works in a Verizon iPhone, but if I manually try to connect to Verizon I get your sim card doesn't support this network error.
I assume I don't need to reflash the modem since I do get a signal after a reboot for about 30 seconds, then it goes away. I also have tried a factory reset, network reset, and verified my imei was still on the phone. I got this phone used with s off and unlocked bootloader already. It was running stock Android for Verizon 7.0. Firware was 2.41 before I updated it to flash the newer rom.
Any suggestions?

I reflashed the modem a couple times, and it is now working. However, wifi calling doesn't show as an option.

Did it work before you flashed it?
Is the SIM locked to your iPhone?
Do you have a network update option? Does the network need time to recognize the new phone? (I haven't used CDMA in years, don't remember beyond it being a pain)

There is a thread similar to this in the Verizon forums.
https://forum.xda-developers.com/verizon-htc-10/how-to/vzw-how-to-unlocked-model-vzw-t3376743/page40
Might not be so easy to get working. Since you're on the verizon network I would just convert it back to VZW software. The Oreo update is supposedly coming soon, and that way you wouldn't have to mess around flashing radios, etc.

I flashed all the way back to 1.85 Verizon RUU, and had to run the erase modem fastboot commands to get wifi calling back. I then flashed Twrp and the newest custom rom based on 2.617 and wifi calling is still in place! However, I lost my home button. I quickly figured out the firmware was still on 1.85 from the flash down to 1.85, so I flashed the newest firmware to match the rom and everything is back working.
