Hi,
I have an international (EMEA, model 0P6B640) HTC One M8 Dual Sim which runs on Lollipop, and is unlocked (bought from a shop, no network/carrier). I just moved back to the USA, to find that the 4G-LTE does not work as this phone does not have bands 2, 4, or 17 unlocked. I wish to unlock them so that I can get a T Mobile or ATT sim card.
I know from reading these boards (thanks guys!) that this should be possible as it is a software issue, and that there is a list of things I need to do like root, S-off, super cim, and then flash the appropriate rom. I can follow clear, explicit instructions just fine, but am not very phone-savvy, and have no idea where to find the files I need or exactly how to do these things.
If anyone could help me out with what I need to do and the order to do it in, I would really appreciate it.

Hi everyone,
i am new to Hermes site, i used to have wizard and knew how to unlock or flush any rom to that phone.
Tomorrow i am getting cingular 8525 which i am planning to use in T-mobile here in US. the phone I am getting is going to be refurbished phone. At&T is replacing the phone purchased back in February of this year.
I know I have to unlock it before I use it with t-mobile. I have read two ways of unlocking it one way is using HTC_Hermes_SIM_CID_Unlock_v3a.zip file but at the same time I read about this way "SIM-Unlock SoftBank X01ht post April (white versions) with radio 1.14.01.10".
since the phone will be refurbished phone, should I treat it as new out of bax when unlocking it? which way should I chose to unlock?
I only have T-mobile sim card, do you think i will need at&t sim card to unlock this phone?
after the unlock I am planning to upgrade it to wm6 and I saw many good roms here: Official HTC rom, Black Magic, Black Satin...which one of these would you guys recommend me to use?
Thank you in advance.

so many views no reply?
can any one give suggestions?
Use the HTC Hermes SIM_CID_Unlock v3a. Worked like a charm for me. It will CID and SIM unlock so you can install whatever rom and use whatever carrier you wanted. You don't need an ATT sim to unlock it either...just follow the step by step instructions that come with the unlocker.
I used the Hacked Radio Version way to unlock mine
worked exactly as it said
and then i SuperCID mine...or you could just use OliPRO
Hi Friends...I need you help Urgently.
I have a T-mobile Unlocked HTC One M8 which I am using on my AT&T Sim card. I would like to remove the entire T-mobile software and would like my phone to have exactly the same software that come with a Factory unlocked phone from HTC.COM. Is it possible? If yes, please provide me step by step instructions on how to achieve it. Current S/W number is 3.32.531.2 Android 4.4.4. Also, T-mobile has blacklisted the IMEI but its working fine on AT&T. (got burnt on craiglist).
OR (if above is not possible)
Can it be converted to a AT&T Phone?
Thanks for your help in advance.

Can't you just install Google play edition rom or custom rom. There is numerous threads on steps.
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:

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.

I got htc one m8 4days back from a store in hyderabad. Everything is great about this device but there are two major problems i am facing.
1 - There is no software update option in the phone.
2 - Not able to access 3g or 4g, only 2g coming.
So i need help on these two points and I am desperate about it.
I got some info about the device that its a rooted device having s off and bootloader is locked.
So Please guide me how to overcome my issue, it will be a big help.
I am not that much tech expert but if you can guide me i can do it.
Thanking you.
The device doesn't support you carrier. You shouldn't have bought it, without knowing in advance whether it would work on your carrier, or researched if/how it can be modified to do so.
The device can be modded, yes. Definitely for 3G, LTE is not certain.
You'll need to find the firmware.zip that supports your local carrier's bands.
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
