[Verizon HTC 10 Guides, News, & Discussion] Homestar1217:
I just ordered a red US Unlocked 10 since they were on sale for $399! I plan to follow this guide to get it working on VZW. This will be my first phone that I take out of the box and flash haha!

I just want to be sure that once I purchase Sunshine, and then flash the latest VZW RUU, I will be able to go back to the US Unlocked RUU if I decide to. I know Sunshine looks like it will operate as many times as necessary on the same device. I just want to confirm that should I switch carriers or decide to sell I can put it back to US Unlocked with no issues.

I have read through the thread, and I believe I've seen that this can be done, I just want to confirm. Thank you in advance!
[Verizon HTC 10 Guides, News, & Discussion] Tarima:
No issues going back and forth between ruus as long as you're s-off.
[Verizon HTC 10 Guides, News, & Discussion] Homestar1217:
Thank you! I followed the guide and am now using my Red HTC 10 on Verizon. Fantastic!
[Verizon HTC 10 Guides, News, & Discussion] hack.causality:
Was it working at all before you bought sunshine? $25 for an app to use your phone on your network seems...unreasonable.
[Verizon HTC 10 Guides, News, & Discussion] dottat:
Useless comment. Read up. That's not entirely what it's used for. *****ing about the cost of sunshine in a Verizon forum won't get you any sympathy and in most cases will lead you to the door.

You will not get service without flashing the Verizon radio.
[Verizon HTC 10 Guides, News, & Discussion] Homestar1217:
I wanted the red 10. Verizon only sells the silver one. I got a $300 discount on the phone, $25 is a small price to pay to use it on Verizon and will allow me to do many more things with it once HTC drops support for it eventually. It's a massive upgrade in power from my old Nexus 6, and I still have a phone I can use on any network I like.
[Verizon HTC 10 Guides, News, & Discussion] aer0zer0:
In most cases with HTC products, it is the only way. To allow a radio flash from a different carrier, or doing the full conversion, requiring swap of the entire ruu. It's the cost of doing business.
[Verizon HTC 10 Guides, News, & Discussion] hack.causality:
My apologies; I clearly hadn't done enough reading on the HTC 10. As I understand it now, there are two unlocked variants, an international one and a US one, with the international one not supporting any CDMA (0,1) or Verizon LTE bands (2,4,13) and the US supporting the correct bands but needing s-off to allow reflashing the radio firmware which is required to use Verizon, whether or not you have an activated SIM.

So, if I see for example an ebay listing that states the phone is not compatible with Verizon but has Verizon frequency bands listed, that phone is the US unlocked version that can work as long as the s-off and radio flash procedure is followed?

In particular this listing http://i.imgur.com/0DJkwic.png in which the seller states the phone is GSM only but lists all the right verizon bands.
[Verizon HTC 10 Guides, News, & Discussion] Homestar1217:
The US unlocked version of the phone has all the same bands as the Verizon one, they're just locked out by software as Verizon sells their own locked version of the phone and refuses to support the majority unlocked devices on their network. It was a fight to get my Nexus 6 activated a few years back since I didn't buy it from Verizon directly, even though they sold the same phone. Thankfully the FCC solved that for me eventually by making it against the law for them to actually block compatible devices from their network.

That being said, finding an unlocked phone that works out of the box with Verizon is difficult at best. You're pretty much limited to Moto phones or the Pixel or iPhone at this point. Not being happy with any of those options and finding the unlocked 10, a phone I've always wanted in red on sale and knowing it could be converted I elected to pay the $25 for the I have to say fantastic Sunshine app. It was about an hour and a half worth of work and I LOVE this phone!
[Verizon HTC 10 Guides, News, & Discussion] hack.causality:
Ah, understood. So if I were to buy a phone that isn't labeled as the International or US version but has the correct US bands, I know it's the US version and can be converted?
[Verizon HTC 10 Guides, News, & Discussion] dottat:
Have you checked out swappa.com? You might even find one already s-off there too. Plus you would know which model you are getting and they take PayPal.
[Verizon HTC 10 Guides, News, & Discussion] hack.causality:
Eh, I'm very anal retentive when it comes to things like scratches and burn-in; a single blemish is enough to make me replace a screen. The non-replaceable battery means a used unit is probably going to be degraded after a year and a half of use. Thanks for the suggestion, though.

Edit: It's come to my attention that Sprint is selling the HTC 10 for $240. Can the same conversion procedure be used to make that model work on Verizon?
[Verizon HTC 10 Guides, News, & Discussion] ahgahg:
verizon demo phones seems to have a stronger signal in db and bars than a verizon customer phone

I compared converted htc 10 with other htc 10 at vzw corporate and other devices.

phones were 10db better as in lower -db number than the owned phone

a lower negative number, -87 on demo , -97 on owned

is that normal or possible, or is it the owned phone with less signal pickup
[Verizon HTC 10 Guides, News, & Discussion] drumz0rz:
Has anyone been able to get HD Voice / Video calling to work?

In my settings HD Voice is unselectable and calling Verizon they're having difficulty adding it to my line likely because it shows up as a 'Non VZW Device' in their system.

It's really annoying losing all Data when I'm on the phone. Feels like I'm back using a 3G phone...

Edit: Looking back through the thread I found this post:

I can try this later today. My question though, say I get VoLTE working on the factory Verizon RUU. Can I then reflash my current nandroid backup and keep the features or will that cause them to drop again? Would the only way to keep everything be to reinstall ViperROM and all my apps+data via TiBu? I'm not opposed to doing that, but if I can save myself the hours of work I'd rather not have to rebuild everything from scratch again.
[Verizon HTC 10 Guides, News, & Discussion] notanexpert:
Will this enable auto updates of Android?

This is a really nice guide, thank you.

1. If I go through this procedure on my GSM-unlocked HTC 10 and move to Verizon (and hence get it working with a Verizon SIM), will the phone then automatically receive Android updates from Verizon?

2. My phone has received many updates from T-Mobile. Is a factory reset part of the beginning of this process? ...edit: I've watched the first 3 videos and yes, the phone goes thru a factory reset process. Assume I'm going from T-Mobile to Verizon--where/how would you recommend backing up my data & contacts? I'm assuming something like my Google account for contacts?

Background:

I bought my GSM-unlocked HTC 10 directly from HTC for use on our T-Mobile account. It has worked well, but we will be moving to an area that has zero T-Mobile coverage, and our choices are Verizon or US Cellular. While US Cellular provides excellent coverage in the Midwest, they do not support the HTC 10 at all, and I'd like to keep my phone. The other 4 phones on the account will be replaced with phones from Verizon with monthly payments.

I guess I should get the 4 other phones working on a new Verizon account, then go online and add my line and have them ship me the new SIM card. There was the discussion in this thread about the IMEI not matching Verizon's database and so the store not wanting to activate the phone. Won't my online order require entering my IMEI?

I've never rooted a phone, but I've worked with computer operating systems and programming for 30 years. How long will this entire process take? What are my chances of failing and/or bricking my HTC 10?

Thank you in advance!
[Verizon HTC 10 Guides, News, & Discussion] Jubawub:
So a quick question. If I get the unlocked htc10 and do the steps to covert it to VZW, will I then be able to use custom kernel and ROMs, or will I have to stick with the Verizon stock rom/ Verizon variant custom ROMs? Also, I want to get this phone so I can switch to T-MOBILE in a year after I've moved back to civilization where I'd get signal. Is it possible to revert the VZW fix?
[Verizon HTC 10 Guides, News, & Discussion] andybones:
Once converted, you will have no issues using custom ROMs. You may also revert at anytime you please to do so. :cool:
[Verizon HTC 10 Guides, News, & Discussion] Waleslie:
OKay. I've followed this threads here on XDA and successfully unlocked the bootloader on my Sprint HTC 10, used Sunshine to switch to S-off, unlocked my sim card, and finally install the Verizon rom on the phone as described in this thread.

Now, I need to do what I suspect will be the hardest part... get the nano-sim from Verizon. My current Verizon phone is the Samsung Galaxy SIII. It uses a full-sized sim card. I bought one of those conversion kits that allows you to put a nano sim into a micro or standard slot, but a Verizon employee told me that when they activate a sim, they activate it to a particular particular phone and it is size-dependent. He said he would not be able to activate a nano-sim to my Galaxy SIII because their system would know that's the wrong sized sim. It's my understanding that if I go into Verizon with my converted Sprint HTC10, the IMEI won't be in Verizon's system, so they wont activate it that way.

What's my best option for proceeding here?
[Verizon HTC 10 Guides, News, & Discussion] michaelbsheldon:
Easiest thing would be to borrow a newer Verizon Android (not Apple) phone that can do HD Voice (Advanced Calling) and activate the sim on that.

That would not mess anything up on the phone you borrow.

Make sure Advanced Calling is enabled on your Verizon account. Everything will work perfect on first startup of your Ten.
[Verizon HTC 10 Guides, News, & Discussion] Waleslie:
...and if I don't have access to a phone I can borrow?
[Verizon HTC 10 Guides, News, & Discussion] andybones:
See if a friend or really anyone will lend you a Verizon device with same sand size sim as Verizon HTC 10. Pretend you bought off eBay, activate to your line then give your friend back phone and keep yournew sim to use
[Verizon HTC 10 Guides, News, & Discussion] andybones:
..No idea..

Cut your Micro sim to a nano sized sim.

https://htc-one.gadgethacks.com/how-to/convert-micro-sim-card-fit-nano-slot-your-htc-one-m8-0154010/
[Verizon HTC 10 Guides, News, & Discussion] Waleslie:
It's a full sized sim card. I'd be concerned the extra thickness could result in damage to the card / phone.
[Verizon HTC 10 Guides, News, & Discussion] Waleslie:
So, despite all the posts about how difficult Verizon is about giving you a different sim card, I though I'd give it a shot. I walked in, told them I was going to pick up a phone off Craigslist, and they just gave me a nano-sim activated to my number.

Now, the phone seems to be having some problem connecting to internet and voice. It can make a call, but it informs me that it is data roaming is on. I'm also only seeing 3G not 4Glte. Is there something I need to update on the phone itself after performing the conversion to the Verizon rom and then inserting the sim card?

I've dialed *228 which just instantly give me a message that "A Verizon Wireless SIM card has activated your service and updated your phone's roaming capabilities." Doesn't actually seem to make a call where I have to select options from a menu as I remember it doing in the past.
[Verizon HTC 10 Guides, News, & Discussion] Tarima:
You ran a Verizon ruu on your sprint variant? I don't think it will ever work on verizon. The Sprint variant works only with the Sprint radio, and if you flash that you won't be able to use it with verizon.
[Verizon HTC 10 Guides, News, & Discussion] LibertyMonger:
This was posted in a Verizon forum...

"FIX: Verizon needs to add HDvoice manually in the billing system. new code .. CDMA list devices.. Tech Support can do this and update your SIM through the network. When you call (and get tech support (TS) on the phone) they will initially deflect you HTC..will not help the issue is Verizon software. As soon as TS hears you have an unlocked phone hey are very resistant... you must persist and ask them to look deeper (into the HDvoice issue) had alll the issues with my U11 (SIM etc)detailed n the forums... today my U11 works as expected"
[Verizon HTC 10 Guides, News, & Discussion] andybones:
This thread is for the US unlocked variant.

I'm not sure if the Sprint variant has all the LTE bands enabled.

Are you running a Verizon RUU and converted it?

You may be able to hack the phone to enable all the needed bands but isn't something I've done or have experience with.

Here is a thread to get you started if this is the case.

Does this still work?
[Verizon HTC 10 Guides, News, & Discussion] Tarima:
Yes, should still work
[Verizon HTC 10 Guides, News, & Discussion] cedarknoll:
Thanks for the guide op!

Has anyone gotten through the activation process with a verizon mvno? Seems like the only options would be to already have an active nano sim from your mvno or borrowing a verizon phone with a nano sim and activating on that and then transferring your sim over.

Unfortunately I do not already have an active sim because I'm coming from a 3g phone. I tried just giving my mvno an esn from a broken moto x I have, they accepted the esn but it didn't work to get put the sim in my htc 10, I guess you have to actually activate sim on the moto x first.

Going into a verizon store seems like not an option if your not a verizon customer, I doubt they would just let me borrow a phone out of the case from a bit while I activate my mvno sim on it. lol

Just curious if anyone has any other options. thanks!
[Verizon HTC 10 Guides, News, & Discussion] golfnz34me:
Why not just request a sim from the MVNO? They should give you one for free if you switch over.
[Verizon HTC 10 Guides, News, & Discussion] cedarknoll:
Sure they give you a sim, but they need an esn to activate the sim. the unlocked variant is not a valid/whitelisted esn for verizon. This is what Step 5 of the OP is about.
[Verizon HTC 10 Guides, News, & Discussion] golfnz34me:
In my experience the phone doesn't NEED to be whitelisted by Verizon in order to use it on an MVNO, as long as the phone supports the right bands. I've used both Straight Talk(Verizon towers) and Total Wireless with unlocked phones.
[Verizon HTC 10 Guides, News, & Discussion] cedarknoll:
Yeah I have experienced the same thing in the past. Not sure when you last tried it, but it was a while a go for me. I guess they have changed things, or its on a phone model basis and we just got lucky before.
[Verizon HTC 10 Guides, News, & Discussion] golfnz34me:
I think the phones will still work, but sometimes they need to have the APN settings set manually. The ZTE Axon 7, for instance, was not whitelisted for Verizon but still worked once you got the APN settings right.

And the MVNOs don't yet support VoLTE.
[Verizon HTC 10 Guides, News, & Discussion] DoctorB0NG:
If you call someone who also has advanced calling enabled, do you get a HD voice quality call?
[Verizon HTC 10 Guides, News, & Discussion] Light1984:
Doesn't sound any better to me. It says HD voice is active on both lines of my Verizon account, but maybe the other phone (iPhone) needs it activated in settings?

Quick Question. I have an unlocked 10 with VZW radio installed. I also just SuperCID the phone. If I were to flash the VZW RUU would I need to change the CID to match VZW or is it ok as it is?

Will I also be able to receive OTA's as well?
[Verizon HTC 10 Guides, News, & Discussion] DoctorB0NG:
With superCID you'd be able to flash the RUU and use it but make sure you change the MID as well.

Even with stock recovery and stock system, I believe you need to be on the VZW CID to take OTAs.
[Verizon HTC 10 Guides, News, & Discussion] Captain_Throwback:
The MID of the Unlocked Edition and the Verizon variant are the same - there's no need to change it.

It's probably a better idea to set writecid to SuperCID, then nothing has to be changed to go back and forth between the RUUs.

And OTAs don't care about what CID you have as long as it's either the correct one OR SuperCID.
[Verizon HTC 10 Guides, News, & Discussion] VirgilWoods:
After installing the RUU and switching back to root with a custom ROM, is the VZW radio over-written? I installed the ICE rom and having an issue with my signal set to "R." After installing the VZW radio again in fast boot I can get internet but no voice.

Did you change the network settings to global? Mine was on R until I switched it to global or LTE/CDMA mode.
[Verizon HTC 10 Guides, News, & Discussion] gleggie:
What is the advantage of buying an unlocked HTC 10 and converting it to Verizon as opposed to just buying a Verizon htc 10 and sending it to jcase? Is it because certain ROMs aren't compatible with the verizon variant?
[Verizon HTC 10 Guides, News, & Discussion] Captain_Throwback:
The advantage is you don't have to send it to jcase ;).
[Verizon HTC 10 Guides, News, & Discussion] gleggie:
So are most ROMs compatible with the verizon variant? I used to have the M8 and a lot of ROMs (especially Aosp) had to be built specifically for the vzw variant

I'm thinking about picking up the HTC 10 but idk if I should spend a bit more on the unlocked variant or just go with the verizon variant.
[Verizon HTC 10 Guides, News, & Discussion] shpotik:
So after having successfully installed this is anyone having issues with weaker signal? I only flashed Verizon radio on mine and it works, but there is a significant diffence between my wife s7 and my previous note 4 comparing to my HTC 10. its at least 1 to 2 bars less in signal and the download speeds are slower as well....I'm wondering if i do this to my phone, will it fix my issue or is that a hardware thing? thanks in advance!
[Verizon HTC 10 Guides, News, & Discussion] xtermmin:
You shouldn't go by bars, as different OEMs and skins have different definitions on what each bar value should be. Compare the raw dBm values.
[Verizon HTC 10 Guides, News, & Discussion] shpotik:
I have compared that as well, i also did download speed test (via spped test app) and still the HTC 10 is slower about 8 out of 10 times, sometimes it randomly drops to 3g where 4G is super strong and would never do on any other phone. a toggle airplane mode on and off fixes it, but still annoying.
[Verizon HTC 10 Guides, News, & Discussion] dottat:
Flashing just the radio is the problem. There's rom support and kernel support needed to fully be optimized for Verizon's network.
[Verizon HTC 10 Guides, News, & Discussion] hardboiledjuice:
I'm in the same boat, studying the options, and here are the pros I've gathered so far of getting the unlocked variant and converting to VZW:

Can obtain s-off at home instead of sending to jcase

Sexy carbon grey color model

Included Uh-Oh insurance with htc.com purchase

Can freely switch your phone to other carriers

Not giving VZW even more of your money beyond your monthly service bill

Anything I missed?
[Verizon HTC 10 Guides, News, & Discussion] gleggie:
Also more ROM compatibility with an unlocked variant but the only thing I'm concerned about is phone signal but from what I've read, RUU fixes that
[Verizon HTC 10 Guides, News, & Discussion] ffuser1:
I'm not having weaker signal but wifi calling and volte don't seem to work in the newest leedroid, ICE, or viper roms. I'm also having issues with calls not ringing and going to voicemail. i personally would say that other roms are not 100% compatible with verizon

Don't I need to re unlock my bootloader. Phone shows as S-off but bootloader locked. I flashed recovery again and got root on the verizon rom just curious it stills hows boot loader locked but I know S-off superceeds all. I got my root and I suppose I can just go with a custom rom for my updates :)

PS: I suppose I should get the OTA before flashing a rom like vipers to have the verizon fixes, though 'd imagine in a future rom update he can include them

UPDATE: I did all of the flashing (tmobile variant) to verizon over wifi. I now just sim swapped and get MEID is empty can not use the phone text message from 0. During the process did it overwrite something?
[Verizon HTC 10 Guides, News, & Discussion] ST47:
I'm real confused about this SIM situation. I'm coming from an M7 with a micro-SIM. Is there a reason why I can't:

a) cut the M7's micro-SIM down to a nano-SIM using the templates online and stick it right into the unlocked HTC 10?

or

b) walk into a Verizon store, pull the "I'm getting a used phone from a friend and need an NFC-enabled nano-SIM" trick, and then activate that SIM in my M7 using an adapter before putting it in the HTC 10?
[Verizon HTC 10 Guides, News, & Discussion] iHTC:
Was the process supposed to leave bootloader unlocked? I am still S off but appears my bootloader is still locked (likely because the verizon rom stock is locked)?

I still can't get service my activated sim, when I pop it in says: MEID is empty, can not use the phone (via a text to the messaging app )
