[Q] m8 verizon convert to HTC Europe

Hello!
i have an Verizon s-off M8, My question is if is possible to convert (change CID/MID) in to a HTC Europe (with a last firmware). I use it only in gsm band. it is possible?!

Nope, as it's a CDMA device not GSM

Sorry to ask this like a month later, but I had a similar question as the OP. Why wouldn't it be possible if I only wanted to use my phone in Europe on the GSM bands? I've been using it with a ROM for the international phones and it works fine. But I was also wondering if I could flash the newest firmware and 4.4.3 upgrade to use some of the newer ROMs for the international versions, like ARHD 10.2.

HI! Can you give me more details? I've just received the verizon variant (bought from an online store) in Europe.. I would like to "convert" it to international version so I could get official updates from HTC via OTA. IS that possible?

I don't think you can convert it over to the international edition, although I could be wrong, since some of the partitions, firmware, and actual hardware (like the CDMA receiver) are different. Given how buggy just some of the ROMs are with the int'l kernel built in, I would be worried about bricking the phone trying to actually convert it to be able to receive OTAs.
What you can do check out some of the ROMs that let you pick which variant to install. After you boot that up once, you'll probably need to reflash the stock VZW kernel (or read around and see if Verizon users got other kernels to work with the ROM). It's kind of trial and error. A lot of times I ended up without wifi or service until I found a kernel that worked.
For updates, (this part sucks) you'll have to wait for the Verizon phones to receive them in the US. Someone usually makes a set a files you can flash since we can't get the OTAs for VZW here and a lot of people don't want to go through the hassle of going back to close to stock to get them. Make a backup, flash those, and go on your way!
But, you'll have to follow the updates and such for VZW phones and then just use a ROM to make it like an int'l versions.
I've been running the int'l version of Paranoid Android and before that ARHD and it's been fine. I used venom and I think n8 before that but it would only install the VZW version so I had to use ROM Cleaner and take out a lot of crap. The roaming triangles were annoying enough that I gave up on venom even though I like the ROM.

THanks for the reply. I think I will return it back.. I wanted a stock experience (eg: when HTC launch an update I DONT Need to wait for verizon to release an update).
I paid lots of money (~700$) for a contract free phone and got a branded phone (not sim-locked by branded is enough) . What a sh*t situation.

Oh God, I assumed you got a Verizon one because it was cheap. I picked mine up in the US for $150 so I don't care so much about having to wait since I saved so much money. If you paid full price I would definitely return it and get an int'l one instead!

Nope, the problem is that I wanted the 32 GB version and most of the online shops had only the 16 GB one. Maybe there is no international 32gb htc one m8..
PS: the retailer's product page (cel.ro) doesn't say anything regarding branding, even the photos are of a htc one m8 unbranded phone.

I am a bit late here. Can i flash a European custom rom on verizon M8? I want to completely get rid of verizon bloatware/services . If yes then while installing custom rom in aroma can i select WWE instead of verizon?? Summary of my question is can i use a WWE European custom rom on version M8??

You should only use custom ROMs that specifically support the Verizon variant. If the option is given in AROMA for carrier version (and VZN is one of those), its got nothing to do with what carrier/region you are located in, but refers to the version M8 you have, which is still Verizon. But you should check the specific ROM thread for details, comments by VZN version users, etc. as devs don't always setup AROMA the same way.
This thread is really old (almost 2 years) and we know a lot more now. FYI, I know its not what you specifically asked, but the topic of the thread is converting to Euro version by flashing firmware, RUU etc. And quite simply and frankly, do not attempt to flash Euro firmware, RUU, or change the CID/MID to do so. Flashing Euro firmware on the VZN variant will result in a radio brick, and the damage may be permanent!

HTC One m8 variants

Hi guys,
Planning to buy the m8 and root it. But should I be specific on the variants?
Im not from the US (The Philippines) so Most likely not gonna get atnt, sprint etc.
So my options are:
The international model
Emea (a friend of mine is selling his but it was bought in riyad, KSA)
Or the asian version (s801 2.5ghz)
Do they have like different model nos.? Different ruus / rom versions etc?
Had a bad experience when i bought a phone (m7 sprint wls) before, since im not from the us. Had limited roms available compared to the international version
Your input would really help
Sent from my HTC One

I would agree that you should not get a US variant. For one thing, they will be SIM locked. Another thing, the Sprint and Verizon versions are CDMA. Different software, and possibly different hardware (although its been discussed here, and not clear - but I would err on the side of caution and assume the hardware is different). So if your area does not use CDMA I would stay away from those variants.
All GSM versions, be aware that they can all be converted to another carrier variant once bootloader unlocked and S-off. So as long as you avoid the CDMA versions, you are good for ROMs.
I would suggest the version that supports your local 3G and LTE bands out of the box. But again, as long as you are willing to s-off the phone, you can change that in software. So if that is the case, I would just go with the best deal.
From what I understand, the Asian version is the same as any other GSM version, just with a slight overclock.

Well if you do go with a us carrier Verizon has the best coverage and thier phones are :not: sim locked. You can use them with any carrier anywhere. My second choice would be t-mobile

The OP is from the Philippines. They aren't going to use a US carrier.
I would advise against CDMA variants for the reasons already mentioned.

Thanks guys, I just want to be clear, so if I use a Rom or RUU on a GSM variant, as long as Im'm on S-Off / Unlocked Bootloader and/ or on SuperCID. I could use any Rom ./ RUU from different GSM variants (I checked the rooting guide for the M8 and is similar to the M7, so as far as unlocking the bootloader / root that I have an idea).
Do they have different RUUs at all??

Aside from the CDMA RUUs, which I wouldn't try on a GSM version unless you read definitive advice elsewhere that its ok.

Only US versions have RUU, that I know of.

Yes you're right.
I thought all has ruus on it. But with supercid i could use any nandroid backup right? As long as its gsm
I think I will go for the Asian version (wwe right? Cause it has a higher clockspeed and updated s801) And go supercid and use international (gsm) roms. Will that work?

WWE just means "world wide English". I think it refers to the Euro version.

[Q] US phone - 4G

Hello.
FIrst , i know there are 2 more threads ( or maybe more , i could only find 2 ) about this but they didn't made me understand my problem.
So I live in Europe and my M8 is an US M8 ( Canadian if i remember right) and because of that 4G isn't working here , in Europe.
Now my question is : Can I do something about this ? I'm s-off if that can help..
Thanks.

Check if your version of the M8 supports the 4G band(s) used by your carrier. If not, the band support can be changed by flashing the appropriate radio.
Also, make sure you are using the proper APN for your carrier. Sometimes carriers use a different APN for 4G enabled devices.

1) Verify what version of the M8 you own
2) Check specs online to see what bands your M8 version is supposed to support
3) Find out what 4G band(s) your carrier uses
You haven't given much detail, and I don't know your knowledge base (what you do or don't know how to do). So I can only give general steps, and rely on you to ask specific questions on the steps above, as necessary.
Flashing the radio appropriate for your region/carrier is probably going to fix the problem. But I recommend you do the research above first, to first confirm that band support (missing in the device software) is the issue.

Yeah , looks like my brain wasn't working when I wrote you later.
I have a T-Mobile M8 and their bands are 700 , 1700 , 2100. For my carrier I need 800, 1800 , 2600 so looks like I need to flash a radio.
I just did a research and found some radio here on xda but i don't know which one to download. ( If you can help me here i would be very thankful )
My phone is s-off so i'm alright , i just need to change my cid to supercid.
---
Yeah . I know Canada is not a part of the US.

Do you intend to run a custom ROM, or keep the phone stock?

I already have a custom ROM - ViperOne

@redpoint73
So can you help me in finding the radio for my M8 ?

If the latest Viper (version 4.x), I would suggest flashing the 4.16.401 firmware package. Not only to get the Euro radio (with the LTE bands you are looking for), but all the other firmware modules that correspond to the 4.16 software, for most bug-free performance.
http://forum.xda-developers.com/showthread.php?t=2696282
s-off is required (which you state you already have) to flash another region/carrier's firmware. Plus, you will need to change to the proper CID and MID.

That isn't the firmware number.
The term "firmware" is a little confusing. On this device, when most folks say "firmware" (including the link I sent you) it refers to a package of modules including hboot, radio, WiFi, Bluetooth, and others, that DO NOT get flashed with the ROM (but are critical in the correct operation of the ROM).
Firmware does not in fact really have a "number", so referring to the software (OS) number that the firmware deployed with is the best we can do. So again, its confusing.
The OS number is bootloader just tells you what software number the current ROM is based. Flash a ROM with a different base, and that number will change. But the hboot, radio "firmware" will not change. Therefore you want to have firmware that corresponds to your ROM.
There is in fact no easy way to tell what firmware package you have installed. The best way is to look at the hboot and radio numbers. So tell me what those say on the hboot screen, and I can probably tell what firmware you are on (although I'm not that familiar with the T-Mob radio numbers).
If you read the thread I linked, it explains it a little further under the big red letters.

Did you flash any firmware packages previously (by the method that I linked). Or was the phone modified by a previous owner?
Now why the WWE Euro radio doesn't give you LTE, is the real mystery. You've used this SIM on another phone before, and had LTE?

The radio number would suggest you flashed the Android 5.0 firmware, not 4.4.4.
Check the APN again. Does it match the APN on the "other" phone?
If the 4.16.401 firmware, and running current Viper, and right APN, I don't see a reason why LTE won't work. You might check the Viper thread to see if there are any other reports of a similar bug.

The APN is good. I'm gonna check Viper thread but probably I'm just gonna leave it like this. I'm gonna buy the M9 anyway when it's available here. Just wanted to make 4G work untill I buy it but yeah. Thanks anyway for your big help Have a good day/night.

What country are you in, specifically?
I think there were a couple countries (mostly Eastern Europe, I think) that had some data issues on KitKat, but I think they had some minor radio updates. And I would think those issues would have been cleared up by now (for Lollipop).

Is there any way to upgrade the LRA model of the One M9 to Marshmallow?

It seems Bluegrass Cellular, (a regional carrier in my area) never approved the update to Marshmallow, and will probably never approve of the Nougat update. So, I'm stuck on Lollipop, but I'd like newer features and the security patches. If my only option is to do something like S-Off, are there any known RUUs that wouldn't break my functionality?
Thanks in advance, the work you guys do is awesome.

If it is a GSM variant, then converting your phone to the developer SKU would allow you to apply the Nougat RUU that is available. If it is a CDMA variant, you are almost certainly out of luck. Software for CDMA is pretty particular to the carrier and generally not applicable between device variants - to the point that attempting it will probably brick your phone.
Please post your OS version (Settings, About, Software Version) and we'll be able to get a better handle on what options are out there for your phone.

Unfortunately, that SKU (512) confirms that your phone is a CDMA variant of the M9. I don't know of any upgrade path available to your device, apart from the carrier actually choosing to produce the software update. I'm sorry to be the bearer of bad news.

That's unfortunate. Thank you for your input. Hopefully they'll make it happen eventually. I'll be sure the next phone I purchase will be fully supported by my carrier, or unlocked. I love my One M9 nonetheless.

HTC Firmware Differences DE vs PL vs US Unlocked

Hi everyone,
I am currently running an HTC 10 w/ Oreo (LeeDrOiD 10 V5.2.3 / CleanSlate 3.18.63) on T-Mobile. I got the phone new on ebay and it was a T-Mobile Demo Unit. Process to get the phone on oreo and leeDroid first was to change phone cid BS_US001 and mid to 2PS650000 and afterwards installed the the oreo firmware. I installed (2PS6IMG_PERFUME_WL_O80[email protected]60322_CNV_0.77_002_release_520336_combined_signed_2)
I have been having issues with my hotspot NOT staying on so I wanted to reflash the original firmware to see if that could be the issue and then reflash LeeDroid and the CleanSlate kernel.
I recently came across an xda thread that had all the Oreo firmwares ([8.0] HTC 10 OREO FIRMWARE) and I am bit confused as to the differences and what I should install. Being on T-mobile of interest is
T-Mobile/DE: <-- Developer Edition
T-Mobile/PL: <-- ???
US Unlocked: <-- Assume this is what my original firmware upgrade was based on even though I do see VZW (which I think means verizon)
Can anyone explain the differences between the 3 above and what I should pick? @Mr Hofs figure I would tag you since you know a ton about this phone

The differences between the firmwares aren't that significant, the main changes are that they have more carrier specific files embedded in them.
You have the hotspot issue on US unlocked, i have the same with WWE general firmware. I really don't think it's related to firmwares though. But try as you wish but you also need to change cids and mids.

I think you are better off trying wwe firmware or US unlocked with its pure stock rom. Way easier than going for carrier firmwares, they won't do you any good.
