[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

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??

Yes.
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?

I believe that will work, yes.
WWE just means "world wide English". I think it refers to the Euro version.

Changing 4G/LTE Frequency

Hi folks,
I have tried searching but couldn't find the answer so apologies if this is covered before.
I have a 32GB HTC One M8 which I bought from Canada. I am in UK and now looking to get a 4G contract however it turns out that the phone frequency is not compatible with 4G network here..
I have read a thread here talking about adding all frequencies but I don't want to root the phone.
Is there anyway I can flash a UK unbranded firmware? Will it add the UK frequencies or is it built in the hardware.
Please advise

Radio support is mostly software based on this phone. You can flash radios between most M8 versions (aside from the Taiwan M8x, dual SIM and possible the Verizon/Sprint CDMA versions).
But modding the phone (s-off) is required to access the radio partition. You can't touch this partition without s-off. Along those same limitations, you can't flash firmware from another version unless you s-off.

You'll need to S-OFF and Root to flash(Convert) your device.
S-OFF to convert it
Root to change the MID/CID to a UK variant.
Even this: Unlock all bands of your Qualcomm device! Use your phone globally! needs Root and "hopefully" it'll work.
As for hardware, it should work anywhere as long as you have the correct radio I would think. Given the "front end solution" that came with the snapdrago 801 to make it a "global" device. I think changes to radio for various carriers are software related and not hardware.
Can read up more on those things yourself though, RF360 Front End Solution for the Snapdragon 801.
Just get S-OFF and convert your device, LTE should work then. Can't recall anyone with a converted device complaining that it didn't work =o/

Brill.. thanks for the response folks.. so if I s-off it all I need to do Change the CID and flash the UK unbranded firmware through the bootloader?

You'll have to make sure both the CID and MID matches the firmware you're about to flash then.
If you bought it in Canada then I think the model ID will probably be something like 0P6B16000 (I think I read in Scotty's MID thread that Wind Canada might be 0P6B13000) either way, you'll probably need 0P6B10000 (European Unlocked and pretty much every European variant).

Cheers for all the input folks

Ended up selling the phone..
bought a new phone now from Vodafone and now got another task. Will start a thread about it.
Regards

Hi guys, I end up in this post. I have an Euro M8 unbranded, unblocked. I dont care to be root or s-off. How can I change the LTE to have LTE band 4(1700/2100) and band 28(700). Is possible?

Answered your other post in the "Help" thread.
Please don't make multiple posts asking the same question.

So.... I'm ready to go S Off and change from Euro unbranded to AT&T in order to get the band 4. Before to proceed, does someone already made this procedure?
Any experiences to share?

Sprint M8 to stock M8

hi there
i have an htc M8 Sprint Device (831C) and i want to change it to a normal stock M8.
I'm in Turkey, I've bought the phone from outside of the country and i can't use some features like wifi hotspot because of the devise is unlocked version. in other words, i want to get rid of Sprint M8 rom.
Is there any way to do this? ıf its possible, how?

Your best bet is probably to unlock the bootloader, and load a custom ROM (that specifically supports the Sprint variant), rather than a "stock" M8 ROM.
Reason being, the Sprint version is a CDMA (includes both GSM and CDMA radios) and actually different hardware from the other "GSM" phones (that you are calling "stock"). Trying to "convert" your Sprint version (installing "international" firmware, radios, etc.) is a very bad idea, as it probably won't work, and might even brick the phone.
Quite frankly, you probably bought the wrong variant for your country/region. Just about any version except Sprint/Verizon would have been better, and could be converted to be the "international" version.

oh got it. i think the custom rom is my only chance. thank you for your interest...

Most definitely NOT... you cannot use firmwares that are not meant for Sprint, doesnt matter what network you want to use it on (I'm not sure about the status of Sprint SIM unlock, you'll need to check that), but do not go flashing non Sprint compatible firmware (or even ROMs, make sure they are Sprint compatible)
