HTC 10 Unlocked, Used Sunshine for Verizon, Changed CID/MID, Process back 2 Unlocked? - HTC 10 Questions & Answers

Hey all...
I used sunshine to unlock and s-off immediately after purchase of my Unlocked HTC 10 and changed the CID/MID to make it a Verizon phone and flash ViperRom.
Now that I'm traveling for work I need to change the phone back to Unlocked to use the LTE bands in another country (buying a SIM card in Japan), and also for it to to work back on VZN when I return.
I'd really appreciate it if someone can point me in the right direction of the steps I need to take to perform this? Hoping I only need to change/flash a couple things to pop in a new SIM in Japan and pop back in the VZN SIM when I'm back.
Thanks all! Hopefully this could be useful for someone else in my situation. I'd venture to guess it's somewhat common...

I've used my VZW 10 in Japan with a local data sim card without issues. Check the operator you're interested in over there and make sure your VZW 10 covers those bands. Else choose a different operator. Also your network settings need to be set to Global instead of CDMA, if I remember correctly.
With that said if you still want to convert back to Unlocked to be safe, just change your CID to Unlocked (or even superCID) and run an unlocked ruu from htc.com. This will wipe your phone so back everything up. Then once you're back home, do the reverse using one of the no-wipe ruus on xda. I would have thought you'd be comfortable with this already since you've done it once before. Am I misreading your question?
One piece of advice, if you chose a data-only simcard there from the provider Docomo (largest one in Japan I think) or one of their subtiers, you will likely have battery drain issues due to your phone constantly looking for a cell/voice call connection with the towers. There is a fix for it but only if you have Xposed installed.

Fantastic info, I appreciate it. I was looking at b-mobile (http://www.bmobile.ne.jp/english/index.html) because it would fit what I need (5GB/21 days/$30) but noticed the bands for them aren't supported by the VZW 10.
What company did you use?
Running an unlocked ruu from htc.com will basically make it a stock unlocked htc 10?
Another option is just getting a mobile hotspot for a bit more money and then can use my current rom... (http://www.globaladvancedcomm.com/pocketwifi.html)

I bought it from some stand at Narita airport called Telecomsquare. I just shopped around the many stands until I found a package I liked and which worked. Oddly enough the shop specifically said they don't support HTC phones, because of bands I think, but I still went with it and it worked.
Yes if your device is originally U.S Unlocked then changing your cid and mid back to unlocked and flashing ruu will work. You may need to wipe your radios after flashing the ruu as well to get rid of any Verizon radio settings.
Mobile hotspot is probably the simplest option if you're willing to pay for it. No need to fiddle around activating a sim card in a foreign airport

[Q] GSM in UK

Hello Friends,
I'm going to the UK within the next two weeks for 12 days, so I'd ideally like to be able to unlock my phone, get a local sim, and use it there.
What ROM does everyone recommend/have experience using? In addition, any preference on carriers for 3G in London on the cheap?
Thanks!

RMK's Ginger Sense custom rom http://forum.xda-developers.com/showthread.php?t=1161411 is based on latest stock, and support GSM as well. Download & keep it on the mSD card just in case - debloated - and should work flawlessly.
While calling Global Support (keep their toll-free numbers handy just in case for oversea use) to get the SIM card slot unlocked, also have them activated the SIM card as a backup & turn on international calling & roaming for the device - local prepaid SIM card from abroad should be easily to setup, APN & browsing settings will load automatically or need to be changed/reconfigured.
Our oversea provider tried unsuccessfully to push OTA the settings to my unlocked device but couldn't, tech. person behind the counter ended up manually editing & changing it while I waited, took about 10 minutes at no charge.

I called to have them give me the unlock code but they said there was some sort of error and that they couldn't get the code without getting in touch with HTC (which they are in the process of doing now).
Could this be because I'm running skyraider? Should I flash back to another ROM (I'm assuming RMK's?) in the mean time in case this would fix the issue? Or is it just a genuine issue on their end, unrelated to the ROM that I'm running?

I believe you will be fine, give them a little time to obtain the unlock code from HTC. (On my last HTC Ozone (WinMo 6.x) global phone with both CDMA & GSM, VZW changed the factory unlock code so I had to get VZW to retrieve the proper code from their own database, as none of the eBay specialtists could generate it).
You shouldn't have to go back to RMK's and it will not change/fix the issues faced. Global support will have walk you thru the unlocking & reboot process, and have you make a test call once it's done to verify. Once it's unlocked, it's good for life even if you flash another ROM or do a Master Reset, etc.
I would just keep a handy oversea SIM (if available) or otherwise an old AT&T or T-Mobile SIM card around (even if it's expired) just to check things out. It's easier to do all this while you are home, and update your PRL just before leaving by doing *228.

[Q] Canadian Virgin WFS

Anyone unlock one of these? I seem to remember reading somewhere a few months back Bell (who now owns virgin) saying they will never unlock it.
However I see that there are "WWE" branded unlocks for my version, wtf?
Here is the url of the exact phone I have - http://www.virginmobile.ca/en/phones/phone-details.html?model=HTCWILD&colour=White
Please no "I unlocked my DerpCellular wfs, you can too!!" stupidity that most of these threads digress into, either you have the exact phone or not. Anyone who lives in Canada and deals with Bell will understand why this needs to be asked
Hey, another virgin canada user.
i have that exact phone (same colour too) with virgin. Mine unlocked just fine via the htcdev unlock. You just need to select the "Bell Mobility WWE" RUU when unlocking it.
unlocked and rooted. bye bye useless bell apps.
be sure to notice that the unlock does a factory reset. back your stuff (contacts!) up before you start on it.
So when you say unlocked using the DEV tool, does that mean its network and sim unlocked? Also just curious, I have a Bell SIM card, can I use this in this phone without unlocking the network/sim?

nope, the htcdev bit only unlocks the bootloader. the sim lock and all the other bits of s-on remain in place. you'll need an xtc clip or an unlock code if you want the ditch the network shackles.
as for the virgin->bell, no idea. there seems to be conflicting information on whether bell/virgin sims are interchangeable or not. some people report it works, other report it doesn't.

Excellent, I was NOT expecting to be able to do this.
And now for a stupid question, what is a good way to back everything up for a quick reinstall?
AFAIK, There isn't one really, other than exporting your contacts and writing down all your apps names, as all the real useful backup methods require root.
OTOH, unless you like customizing extensively, it should only take a day or two to get things back to normal.

Updating att branded phone t-mobile

I have an s-offed att branded phone on t-mobile. It's running an old ruu t-mobile. I just downloaded an update to lollipop. I can just run the update?
Possibly...
you need to check a few things... what's your phone's cid set to? (you can see this in your boot loader screen).
As a general rule, I've found that if I run t-mobile radio's I have more problems than if I run either a native AT&T or the DEV edition radio and then t-mobile firmware on-top of that radio... my phone doesn't seem to do some of the hspa bands from t-mobile...
check your cid, before you do much of anything else...
If he's running a tmo ruu, i would assume he's running super cid.
I would also have to assume that he's changed the mid to tmo?
scifan, have you considered using DFS to set your bands?

What is the mid and DFS?
I have a Verizon branded m8 and am using a t-mobile mvno
(straight talk) SIM. I am considering changing RoMs from viper one to one off if the t-mobile thread in order to solve this problem of random service disconnections. Should I switch to a different Ruu? Should I have changed the RUU when I was on stock?
I apologize if the this should be on another or is own thread.
Thanks so much!

DO NOT, repeat DO NOT try to "convert" your Verizon M8 to T-Mob (with T-Mob RUU). The partitioning (possibly hardware) is different. The T-Mob RUU won't work, and may result in a permanent radio brick.
I'm not sure what is causing the service disconnects. Does the issue occur if you only use 2G and 3G? You may consider looking at enabling the proper LTE bands used by T-Mobile. From what I see, the Verizon M8 supports the proper bands that T-Mob uses for 2G and 3G. However, the VZN version only supports one of the two LTE bands (Band 4) used by T-Mob (Bands 4 and 17). Enabling LTE band 17 may or may not help. The missing support for LTE Band 17 may be related to your disconnect issues, but that's just a theory.
The hitch here, is that trying to enable LTE Band 17 requires s-off, which costs $25 by sunshine app (if you are not already s-off). And its not a sure solution, so may be money wasted.
You can take a look at the following threads, on how to enable bands on the Verizon M8. But I don't personally vouch for these:
http://forum.xda-developers.com/htc-one-m8/general/how-to-convert-cdma-m8-sprint-vzw-gsm-t3303812
http://forum.xda-developers.com/htc-one-m8/general/unlock-bands-qualcomm-device-phone-t2880239
Awesome thanks. I paid the 25 dollars for s-off already to root the phone. Sunshine works like a charm.
I'll check out the links you provided. I have a feeling your theory is correct. You described how I felt the problem was but lacked the knowledge to produce words to describe. Thanks again.
I don't know whether this is the right thread to ask this question but if you do know kindly advise me; i recently bought a T-mobile M8 which was imported from USA and had sim unlocked but i don't know other details except that its not rooted (that i checked with supersu). May be it was imported as scrap since it's an old model and may be it was unlocked from t-mobile, i just have no idea. Now the phone is asking me for a few updates which describe to tell me that these are intended to prepare phone for marshmallow update (currently it's on jellybean). Should i allow update to progress or not? i don't want to loose sim unlock.

Sim unlock options for GSM Variant

So, after searching the forum, I haven't found anything that really answers my question...
I have the GSM Variant of the HTC 10. It's currently locked to Bell Mobility in Canada. I am looking to unlock this phone without paying Bell the fees they charge for unlocking. From the XDA searches and reading I've done, it looks like there may be a free way of accomplishing this... I found a post that indicates that the Sprint method may or may not work, but you need S-Off...
I found another post that suggests its the exact same as the HTC One M9 and I can use the directions from there. It also indicated that it was only for the Sprint HTC 10 too...
My question is, is there a free unlock method for the GSM HTC 10? Or does it only work with the Sprint version?
According to some googlling, you share the same phone as US unlocked model, based on MID (model ID). You would need S-off to flash a different modem though. modem partition is blocked by s-on feature. sunshine app and java cards are the only way to S-off. both are paid though, sunshine $25.
CID: BM 001
MID: 2PS650000
proceed at your own risk and research well :good:
Right. I think I knew that... ...which means that changing the CID would allow me to flash any RUU for Model 2PS6500, and should theoretically work period.
Which leads to another question I had after posting... Would flashing the US Unlocked RUU remove the sim lock on the phone? I've heard that an RUU replaces everything on the phone with pristine, shiny new code straight from HTC... Would this also replace the code that effectively locks the phone to Bell?
If that is the case, this could be far too good to be true...
Edit: Almost forgot. Perhaps slightly off topic, but what is a java card?

I've read that changing the MID/CID and flashing a modem is enough but.... since I can't quote it I cannot help you with that unfortunately. but should give you a running start, good luck
Thanks a bunch for the info. The thanks button didn't seem like enough thanks for the info.
Also, I'll post my procedures and results here, so if it doesn't work, at least we have a record.

you're welcome and I just google searched quickly and didn't find anything solid but again I'm sure you'll figure out a way.
So, just an update.
I used a website that allowed me to use trialpay to get my SIM Lock code, which worked beautifully.
Unfortunately, Bell Mobility seems to be in the market of continuing to cripple their phones... I've inserted my Rogers sim card and found that voice and text both work on Rogers. Data, does not (cannot set APN settings, not don't know how), along with LTE. Given that the phone supports all the bands that Rogers uses in Canada, I would not be overly surprised to find out that Bell crippled the radio firmware to ensure that the phone would perform it's best only on the Bell network. Heck, they did it with the CDMA Nokia phones, and with the old school Blackberries to ensure their revenue stream...

Maybe now is the time for that s-off and flashing of U.S Unlocked ruu.
The other thing you can try before spending the cash to s-off is unlocking your bootloader, flashing a custom rom and seeing if you can add a new apn from there. I'm very much surprised Bell would block that btw, I've unlocked Bell gsm phones and added new apn settings in the past.
While with XDA im all for free unlocking etc, if you are not S-off then it might be a bit hard
https://sim-unlock.net/site/HTC/10/
Ive had a stupid amount of phones and ive used these guys everytime ive needed a SIM unlock done.
Never failed once and if you can spend the money, it might be worth it in your case here... Against s-off - $25...
For me its a no brainer... I mean for 9 euros?....
But if you have already unlocked and they have crippled it like you say, then deffo go for s off
Fellas, correct me if I'm wrong, but if the SIM is unlocked, then all that's needed is to unlock the bootloader. That can be done for free via HTC Dev if you have tech chops, or via Sunshine (probably the better choice anyway). Then all that's needed is to change the CID and MID, and flash a WWE RUU. That would solve the problem, no?

Yeah that's what I was suggesting as well. Bootloader unlock and flash a custom rom first to see if he's able to add new apns that way, and if that fails just go full s-off and run the unlocked RUU (unlocked is the better option here over wwe, same mid I believe and better support for updates).

This is my thinking... I wanted the US Unlocked version anyway, but got the Bell one since I live in Canada, and was with Bell anyway. Actually, the SIM lock and the bootloader lock are two different locks. You don't have to remove the Simlock to remove the bootloader lock.

I thought about it, but in the end I want US Unlocked due to speediness of updates as well as no more Bell tainted android.
Here is why I suspect Bell blocked it... When I go to view available APN's, all it shows on screen is a message essentially saying APN's cannot be added for this provider.. Also (took me a bit to clue in), LTE doesn't work on Rogers. If I had to guess, Bell wanted to make sure all the HTC 10's it sold stayed on it's network. It wouldn't surprise me in the slightest... The Nokia 6275i was a kick butt awesome CDMA phone back in it's day. AMAZING call quality. Think VoLTE quality on 1xRTT. I don't know how they did it, but it must be a mix of pixie dust and unicorn blood... Anyway, every 6275i Bell sold was severely crippled. No Nokia Maps, just Bell's lame interpretation. Google maps wouldn't work either because it couldn't access the GPS, only Bells navigation app could. Couldn't set a custom ringtone unless it was purchased from Bell. Yet every other 6275i didn't suffer from these issues... Just ones sold by Bell.
So, an update to those interested....
I am now S-Off running US Unlocked firmware.
CID: BS_US001
MID: 2PS650000
Flashing to US Unlocked firmware seemed to do the trick for data. I can now set APNs and data does work. YAY!
Things to do:
1) Figure out why LTE signal sucks...
For whatever reason, the HTC 10 doesn't get LTE at home... I had a Samsung Galaxy S7 (SM-G930W8) briefly which didn't always get LTE at home, but it at least had useable signal, whereas the HTC 10 doesn't, at least not on Rogers. When flashed with Bell firmware it worked as good as the S7 did. I have a theory that when I ran the RUU to change firmware variants, it didn't update the modem firmware... Also, upon further research, it looks like there are partitions that store configuration data for the modem called modemst1 and modemst2, which I'd bet are still configured for Bell, which means they probably set it up to never use LTE on another Canadian network unless you can't get signal on anything else...
2) Figure out how to change Device Certification back to certified.
I'm pretty sure this is because the bootloader is still unlocked... I'm going to try setting it back to locked which shouldn't make a difference to my ability to flash because the phone is S-Off anyway but it may make the difference to Google's Device Certification
3) Maybe try an aftermarket rom, etc... Basically whatever I want.
I actually quite like HTC Sense... Not sure I want to get rid of it just yet. Was thinking of going with Viper due to Wi-Fi Calling being enabled/supported since Rogers supports Wi-Fi Calling, and I refuse to believe I can't make it work on here... It worked on the S7 (same model my wife had on Bell), so why can't it work here? I am also open to suggestions as to good roms to use, so if you think it's good, let me know what rom and why and I may just give it a shot...

Yeah, I found the bootloader thing in another thread, thanks for the follow up though.
I've tried flashing US Unlocked, was prompted for a sim unlock code when I put a Verizon sim in my Tmobile phone.
So I tried flashing Verizon firmware, it told me that my verizon sim... was not a verizon sim.
Did the modem reset, didnt make a difference. Not sure what else to try.
Updates
So, as an update to any parties interested,
I've resolved some of the data issues I was having, where data didn't seem to work unless I was using LTE.
It seems that it's a joint problem between me and Rogers.
My problem was that even though the US Unlocked variant appears to be using the same radio firmware as the Bell variant, the Bell variant seems to have better programming, since I've been getting stronger signal in more areas, as well as slightly better throughput on HSPA connections. The issue I had with APN's and Bell firmware seemed to sort its self out after flashing back to the Bell variant from US Unlocked.
The Rogers end of the problem, is the Rogers network in Manitoba appears to have been a joint venture between Rogers and MTS, prior to MTS being bought out by Bell Mobility. Now that Bell has taken control of MTS, it sounds like Bell realized a lot of the MTS equipment was outdated, and has been attempting upgrades, which seem to be causing more problems than what they're worth. A co-worker is with MTS, and has been having a heck of a time with all of his services from MTS, and the technician's he's spoken to have led on to some deeper issues than what he's seeing. I would imagine that since the agreement was between Rogers and MTS originally, that Bell will have to honor that agreement for at least some time, which (to me) says that my HSPA data slowness could be due to Bell attempting to update the shared hardware between MTS and Rogers.

I'm not sure that flashing the VZW firmware would write to RFG_8 (the simlock partition)... If that simlock partition hasn't been rewritten, you're phone is likely still locked to T-Mobile, but with no way to unlock it though the VZW firmware since AFAIK T-Mobile uses an app to remove the simlock. The modem reset would only reset the parameters of the modem, not remove the sim lock...

T-Mobile HTC 10 to Verizon (Straight Talk)

So I recently moved to a rural part of Ohio, and Verizon is about the only carrier that works here. I have an HTC 10 T-Mobile variant that I Sunshine S-Off'ed and flashed to an HTC branded phone. T-Mobile just game me my SIM Unlock code, and the phone does recognize the new Verizon Sim card. However there is no service at all. So do I still need to flash a firmware?
I really need this to operate on VZW service instead of T-Mobile.
Anyone successfully done this? IS it simple and I'm just missing something?
Thanks in advance.

You'll need to have the verizon radio running on it. You could just flash that, as mentioned here:
https://forum.xda-developers.com/verizon-htc-10/how-to/vzw-how-to-unlocked-model-vzw-t3376743
In that case you may also need to reset your radio settings to get full service, and it's also described in that thread.
Or, better in my opinion, change your cid and mid and flash the verizon ruu.

Hey thanks! I will look at both options. I am going to use Straight Talk for the carrier since its dirt cheap. I jsut need it to operate on VZW towers.
Thanks again.

Do you know where I can get the instructions for the MID/CID and the RUU files? Its been a while since I changed mine. I would like to try the verizon thing first and see if it works on straight talk. IF not, I would like to be able to flash back to TMO so I at least have a working phone.

Conversion process is described here:
https://forum.xda-developers.com/verizon-htc-10/how-to/guide-convert-unlocked-to-verizon-t3380615
Verizon RUUs are found here:

I'd use a Nougat RUU from the above link until you're sure you're sure you wanna stick with the Verizon software. If you install the Oreo RUU, and then downgrade back to T-Mobile which is still on Nougat, you'll lose your radio and will need to to an extra step to get it back.
