Hello, I'm having a major problem with my phone and I'd be extremely grateful for any help or expertise.
PROBLEM:
I cannot get any kind of CDMA signal on TWO Verizon HTC M8 (I didn't post in that specific thread for a reason, I'll explain, please don't move it).
--------------------------------------------------------
HOW THIS HAPPENED:
The first phone, I was using as normal and it was fully functional.. One night i flashed a ROM and ended up falling asleep before if built the ART cache (so it was just playing the bootanimation) and the next morning I awoke to find the boot animation still running. The phone wasn't hot but ever since then I could never get any kind of CDMA service (so i can't use my carrier.)
The second one i just bought and put my sim in and BAM. Same problem.
--------------------------------------------------------
MORE DETAILS ON THE PROBLEM:
If i put my sim in, i can usually get 4G data but can NEVER get any lower bands. CDMA settings are greyed out in settings. This persists across ROMs and radio firmwares. My immediate thought was to get a new sim but my sim works absolutely fine in my LG G2. The sim is cut from a microsim but the point there is it worked fine before (and still works in my G2) and it didn't shift in the tray. I tried my friend's sim from an Iphone 5s and it did the same thing. I've tried everything i possibly know to do. This problem has basically cost me $400 dollars or 2 M8s.
Even if i go into the phone info hiddenmenu, i cannot select the CDMA or EvDo bands by themselves.

I picked up a mytouch 4g Slide (not the MT4g) to play around with for myself but it gets no signal at all. There is an X. No bars.
Now I know on an older GSM phone with no SIM installed... it gets signal. I would guess for emergency calling. I DO NOT have a sim to test this phone with, but I was almost sure it should still show a signal. I have tried indoors and out where Tmo is pretty dominant in signal.
Wifi works, but does the internal antennae support both the wifi and phone? are they seperate antennas for both?
Does someone have one at their disposal to check this out for me? Should there show a signal with NO SIM?
I really dont wanna activate this without knowing if it works.
Everything is stock, rooted, 2.3.4. But was showing no signal even with stock/unrooted PG5?IMG redone over and over. The phone is S-ON/Unlocked (locked made no difference.)
Z-Device (device testing app) shows an X for ANT. Hence the antennae question, but like I said, WIFI works.
Thanks for your anticipated assistance.
No sim no bars, any phone I've owned has been this way
For the record I did not take out sim to test

A GSM unlocked AT&T P506 (LG Thrive) I just pulled out the cheepy bin shows full signal strength with no SIM.

First ever hearing of a device that does such. Every phone I've ever owned (quite a few, however all android) will not show that it is connected to a network without the sim card installed nor when it cannot read the sim that is in it.
I'm not calling you a liar, simply stating this is different from all my prior experience. You won't be showing any signal in the status bar but you should technically have access to 911 & emergency contacts if need be.
I am kinda new to the whole GSM thing, been working exclusively on CDMA for some time now, hence the question when I seen another GSM phone shown a signal. The only difference I noticed outside of the obvious, is that the phone showing a signal is network unlocked, where-as the MyTouch 4gs is not. Would that make any difference? Is each phone different?
Not that I know of, pretty much ever phone I have used is network/sim unlocked and I've always had the same result. I used to buy, fix up, and sell phones on eBay and I've gone through in the hundreds, nearly all I would sim unlock (and root if android etc) and to my recollection I always needed to put a sim in to test if service worked, without I could use WiFi no problem but no bars otherwise

Thanks for the input peeps, I will go ahead and activate anyways and check.
Again, thank you all for the fast responces.
You all was right, thanks, it works.
My husband finally let me root and rom his S3 (I have a Gnex). Unlocking the bootloader and rooting (using Odin) went well. When I installed SlimBean+GApps, however, we started having an issue. He kept losing 3 & 4G signal. We didn't know about the roaming issue, so I had not backed up the IMEI. I flashed Clean Rom, and the issue is partially fixed.
The phone's signal is fine now, 3-4 bars 4G most of the time. The trouble is, we can't dial out to any numbers, and any calls to the phone go straight to voicemail. We've pulled the sim card and let it sit for a bit, but that didn't help. Dialing *228 (as Verizon tech support had him do about 4,583 times) just brings up a message about the phone being activated by the sim card, and roaming capabilities being updated. All tech support had to say was that Google Voice was probably the problem, even though we've both had it for ages with zero issues. :/
Any ideas? I don't really want to unroot and take it in to the Verizon store, but I will if there is no alternative.
EDIT: Just discovered that 4G is only working when "Preferred network mode" is set to Global, rather than LTE/CDMA.
*228 is for 3g phones only, it does absolutely nothing for LTE sim phones. Here's your solution btw.
I knew it! I kept telling them I didn't think that was supposed to do anything when I have a sim card. Crazy first string tech support. They also didn't know my battery was removable.
Will try the things listed in that link, thanks.

Haha Verizon lost credibility with me when I rented their global phone for travel last summer and when I got back to the US the instructions to get my GSIII working began with dialing *228. There wasn't even a warning about it being unnecessary for LTE sim phones.
Good luck and let me know how that goes.
Starting this October, PagePlus is offering 4G/LTE. Initially, I was assuming that all I need to do is plug in an LTE SIM card and activate account, and all will be peachy. However, it seems that by flashing phone to pageplus when it looks like a 3g device, I have messed up some radio settings, and verizon provisioning doesn't work, phone repeatedly keeps trying to call *228. Contrary to that, the other S3, which I didn't flash does not call at all, but instead pops up message box stating that the phone is being programmed, and after a couple minutes it's online . I do not remember what exactly did I program, it was awhile ago . Pageplus support knows that problem, and they are advising anybody who wants to go LTE to bring up an unflashed phone, saying the flashed one won't work
There are folks on kitty forums who offer remote de-flashing for 30 bucks, but no description what actually they do. Does anyone know what the process is? I can get my phone into QPST/DFS. Anyone knows what to do next?
UPDATE: see post #3 for solution
Can't help you with deflashing, but I will tell you that my local page plus vendor did mine for free and it only took him about 5-10 minutes. Maybe yours would do the same. Just a thought.

I guess it indeed is simple once you get to QPST mode. I used DFS to program, and the only setting I had to change was RuimConfig = RuimOnly (from NV_ONLY), see screenshot attached. Did not work on 4.0 firmware which I tried to use first, but worked fine on 4.2.1 and 4.1.2.
I got a sim card for my phone. All I did was verify that my phone was on RuimOnly (it already was), then I contacted PagePlus to activate my simcard (you're supposed to do this before you put it in your phone, they say) and they remotely programmed the phone, everything went smoothly. I have 4g data now, no "unflashing" required. Pretty easy. :good:
You put it on your phone before, you want this set up, then you can use the phone, so no problem.
Confirmed
I can confirm this works. I switched 2 samsung galaxy note 2 SCH-i605 from 3g to 4g.
The phones were originally flashed over to pageplus using wireless workshop. This puts them on pageplus as 3g phones. They drop the last digit of the MEID so it is a 14 digit code (3g) instead of 15 digit for 4G.
Here's what I did to get 4G LTE working.
Ordered a pageplus SIM card from pageplus
put the simcard in the phone
Used DFS to change RUIM from NV_Only to RUIM_only
Contacted Pageplus on chat and had them change my phone from 3g to 4g. I'm not sure exactly what they did, but I gave them the 15 digit MEID and the SIM ICCID (printed on the sim card you get, or look in settings, about device, details or something like that, you know where to look. ) The customer service rep said that what you need to tell them is you want to change a 3g phone to 4g. I told them it was back to standard firmware just to make them happy. It seems the RUIM changes is all you need.
Voila! Reboot the phone, give it a minute - it connects to 4G and then disconnects and looks like it has failed, but give it a minute and it comes up with 4G LTE and speedtest.net confirms it is blazing fast.
Loving it!
This is only required for a verizon phone that has been flashed in the past to make 3g work on Pageplus. Not needed on contract phones from verizon that are originally 4g.
Happy downloading!

Gift for a friend
hi everyone,
I have a few questions based on my circumstances. I just deactivated a S3 Verizon from PagePlus which was flashed to 3g. I would like to hand my phone off to a friend as he's running a Droid X (!).
1. From what I understand to "unflash" I need to use DFS (cdmatool.com) and set Ruim config to RuimOnly. However, I believe the phone needs to be in QPST mode? I'm not entirely sure how to do this. Can someone point me in the right direction?
2. Since I already deactivated the phone, when my friend tries to re-activate on pageplus (with a new SIM), do we need to contact PP and tell them this device is now 4g?
3. Does it matter that I have a custom ROM running 4.3? I don't think so, but would like confirmation.
I really don't want to mess up this gift.
Thanks for any and all advice!

In general, this is done via USBSettings dialog, see if this thread helps you to get this menu enabled: http://forum.xda-developers.com/showthread.php?t=2227576
I have a i605 currently flashed to page plus 3g can't write with dfs without spec and I can't seem to get it can anybody point me in the right direction
I'm dumb figured it all out except page plus they keep saying I have to go to a dealer I said I am no longer flash but they keep telling to have a dealer manually flash it.....?
Update got everything working once I was in ruim only I called them at told them I had two phones and gave them the full imied as my second phone then the iccid and voila activation was a breeze
Hello,
I am from India. I had purchased a Google Nexus 5 phone (Black/ 32GB) last year (December 20th, 2013)
I have started facing a serious issue since yesterday. My entire mobile network went down all of a sudden. Tried using other SIM but of no use. The same SIM works fine in other phone. Other functions including WiFi in Phone works perfectly fine.
A couple of things that I noticed are:
1) When I try to search for the Network manually, I get the message "Error while searching for Network".
2) I noticed that the PREFERRED NETWORK TYPE is defaulted to LTE. I cannot select any other option 2G or 3G.
3) When used Choose Automatically option - it starts with Automatic Registration and then flashes an error "Can't connect to this network right now try again later"
I tried doing a Factory reset hoping that it would work. But, no success. Have contacted LG Direct Service Center (since I bought it from retailer and not from GooglePlay store) and they suggested it's a PCB problem and it needs to replaced which would cost me around 12K INR. Which I am not ready for.
Please let me know what needs to be done. Any help is highly appreciated.
Regards,
Vijay

He's clearly not in airplane mode.
I have tried with all basic troubleshooting options, kindly check the attached screenshots. Please please help needed urgently.
I was going to make a new thread, but his problem matches mine almost exactly.
Hi guys, i have this problem for over a week now.. A very frustrating week i must say. I got this n5 about a month ago, my uncle got himself a G3 and gave his nexus to me.
Everything was smooth, amazed by the phone, everything working fine, happy as hell. It all crumbled when I went to spend the holidays at my brothers, where he lives my carrier doesn't work (everyone uses another one). When i got back to my house where the mobile network works fine it just stopped. All other sims would work on my phone and my sim work on other phones.
I gave it a time, thought it would be cause i spent too much time on my brothers and it would be ok after a while. It didn't. Then i started to worry and try to fix it somehow. First i got a new simcard (same carrier), no bueno. They told me to restore my phone and stuff, it didn't work. The phone has always that empty triangle, doesn't matter if it's 3G, 4G or 2G.
So I came to the internet look for help. I saw that some people had bring this to the LG, their response was to do a recovery with fastboot and then put 2G on the mobile network. For a moment i thought it was over, my phone finally had some bars !! But to my disgrace I can't make nor receive calls, i can only send/receive SMS and access internet thru 4G, not 2G as the support said. Oh, if i put 3G or 2G dem bars go missing and the empty triangle ****er appears again. Still, my simcard works on every other phone but now only one carrier works on my phone (not mine unfortunately).
Then I started looking on forums like this one and a whole bunch of others and tried many things, all of them unsuccessful.
I tried many things, maybe forgot some but will list those that i remember.
I tried to flash the factory rom. Then tried to flash only the radio of previous androids (tried too many of them to count). Dialed that *#*#4636*#*# or smth, put LTE/GSM, only LTE, activated/deactivated radio. Airplane mode on/off. Tried to recovery on fastboot again. Tried to make new APN. To finish my story, put a Cyanogemod rom and it also didn't work.
So now i decided to post here as my last shot before i go to that carrier that still works. Also, what guarantees that this carrier won't stop working like the others? I'm afraid that may happen. Further informations, i saw many people complaining about T-Mobile and other carries, but I'm brazilian, so it's not one of these. My carrier is Oi and the one that still works is TIM.
The two threads i got most tips were these and some sites in portuguese:

Hi,
I hope someone could help me save a useless phone.
I got a Z3 from ebay (it's O2 Germany). As soon as I turned it on it updated to 5.0.2.
Then later I inserted the SIM card (took me some time to get the nano from the carrier).
It's not SIM locked.
The problem is that I can't get a steady signal. AT ALL. It hits a signal for 2 sec, then nothing.
It can recognize my carrier in the split second that it's on, I got the access points and all. I can even search for carriers and get a list of several to choose from.
The same phenomena is apparently happening with the NFC - the software switch turns on then straight off (same radio chip issue?)
I have tried GSM only, WCDMA only, LTE.
Tried changing the bands used using the internal *#*# menus.
Using flashtool I have flashed a stock global rom instead of the german. And local stock.
I have read that some people had this issue after the lollipop update so I rolled back to stock 4.4.4, same issues with cellular and NFC.
I'm really at a lost. I have this fancy brick that I was hoping to give my dad (he needs the screen size, the old fool) and instead I'm wasting valuable time at work trying to fix it...
Anyone?
Thanks,
Juv.

I got the exact same problem, im in Norway and using mye Operator firmware..
I'm having the NFC problem. I have the US T-Mobile version (D6616), and NFC stopped working right after I updated to Lollipop.
Factory reset, and repairing using Sony's PC Companion does not help. On first boot, i'll get a "NFC firmware update failed (-1)".
