[Q] Flashing Chinese M8w

Hi, I have a Chinese HTC One M8. They call it M8w, not sure what the w is for, but anyway. I don't have Google Play Store and tried installing it in different ways, but it doesn't work. My goal is now, if possible, to make this phone non-Chinese software-wise.
Do you guys know if it will work to install this "stock ROM" on my phone?
[SYSTEM DUMP][26.03.2014] HTC One (M8) *STOCK* ROM | 1.54.401.5 | KitKat 4.4.2 | HTC Sense 6.0
Thanks for any help!

For the M8t, there is a easier way for Google Play service (gmail, map... etc),
Just search "GMS安装器" from HTC App store or Baidu App store. Then you are good to go.

Is M8w the Dual SIM variant?

I bought mine from Unicom, and I think it's unlocked, but I don't remember if I tried a SIM card from another carrier or not.

If you want to rollback, you need to restore from a backup you took before flashing. You could also try one of the stock ROMs out there.
Here are some threads where they have gathered links to stock ROMs.

[Q] HTC one M7 Verizon unlocked Update issue

Hi. I have an HTC One M7 unlocked. I am currently using an AT&T sim in it. The problem is I can't seem to upgrade my phone to the new sense 6.0 since it requires the phone to be on CDMA network to update the software which is kind of lame since it's unlocked now. Is there a workaround for this or do I have to install a new rom? Thanks. Any help would be appreciated. :fingers-crossed:

T Mobile M8 could not be activated on Network

Greetings. I have bought a T-mobile M8. I unlocked it and also twrp custom recovery done. Bootloader 3.19. S-ON. My problem is I am trying to use it in Europe but it is not working.. only offline mode. I am a happy h/k Sprint M8 user since 2014 and I have bought this for present, but I can't make it working. Do these unlock codes ( I have found for 9$) would do the trick? If sunshine works, what should I do after that to make it working?
Thank you very much!

some m9 settings are missing

I've bought second hand m9 , this last was flashed and rooted because I found supersu integrated with it, the problem is some settings are missing comparing with regular m9 like mobile network sharing for example, is there a way to fix the problem?

First of all, never use a second hand device without reinstalling the whole OS. I factory resetted my M9 right after buying it. (And rooted it, etc...)
Just look at you CID and MID and find the latest RUU for your phone and install it.
Maybe the person that had it before removed the certain settings, because the HTC settings app is quite modular from what i've seen. The settings app is split into many apps. Probably when debloating it he accidentally deleted that. (For example, if you install HTC's chinese performance management tool, a new setting will pop up in the settings app. Same with Sense Toolbox)
Or if is already rooted, just install S-Team ROM (sun_dream's ROM).

where can i find cid mid numbers?
and what is the best rom should i install?

I suggest you first install stock rom.

I have been searching for a while for how to update the rom image
I checked my phone and I found the following information:
***unlocked***
htc_himawhl pvt s-off
cid-11111111
os-3.41.651.4
feb 3 2016
I believe that my phone was for developers, so I downloaded devRUU "HTC One M9 4.30.617.12" from HTC website and I tried to install it but I got error 132 (get the correct RUU...)
I switched to another RUU "HTC One M9 4.27.651.4", but I got the same error error 132
I've tried to get my CID and MID numbers using CMD but I've got nothing, it shows me:
CID:
MID:
nothing, blank, no information. after some research I realized that it was CID free "unlocked"
the main question is, how can I upgrade my system to get my full setting options? I appreciate your help

Forget whatever you read. It's wrong and you should thank whichever god you believe in that the dev edition RUU didn't get flashed.
First of all, you own the Sprint version (SKU 651) which is a CDMA device. The dev edition RUU (SKU 617) is meant to be used on GSM devices only. Those are two completely different technologies used by different US network carriers. Flashing GSM files on CDMA devices or vice versa leads to unrecoverable hardware damages in most cases since those versions have different partition layouts. It's not even safe to flash Verizon (another CDMA carrier) files on a Sprint device or vice versa since even these models use different layouts.
Second, there is no such thing as an HTC phone without CID. The dev/"unlocked" version has CID BS_US002. If the app doesn't give you any info then it's not working. In addition, it's recommended to use the current firmware version for finding the correct RUU instead of MID and CID. With the latter you still need to guess a lot whereas the former gives you the exact version of the RUU that is flashable.
Btw, you should get rid of the SuperCID your phone is currently using (11111111) since it causes more problems than benefit.
You'll never be able to flash a 4.x RUU on a phone that uses firmware 3.x. The encryption keys changed between those two firmware versions. You'll need to update the phone by using unencrypted files (OTAs or - if you have S-OFF - custom made 4.x firmware packs). You should have S-OFF since getting the SCID is impossible without it (the same applies to getting rid of it). However, Sneakyghost doesn't support CDMA devices so I don't know whether there are any custom firmware packs you could use.
If I were you I'd take the time to carefully read the ReadMe thread and to make sure that I understand everthing. Then I'd use the conversion guide for getting rid of the SCID (you can ignore the warnings if you use a RUU for your current SKU 651). Afterwards, that phone should be able to receive 4.x OTAs so that it can get updated to the latest firmware.
Sidenote in regard to the original question with the missing settings: I could be wrong but if I'm not mistaken then it's completely normal that Sprint models lack the network sharing option since that carrier doesn't allow it and therefore asked HTC to remove that option.

what a wonderful explanation, it's all clear, thanks a lot!
one more question,
how do i know for sure that my M9 is CDMA and has not been only changed to sprint rom version ?
I've googled for the differences between CDMA and GSM, I found that CDMA network basically depends on the device itself, whereas the GSM network depends on the SIM card. However the Sprint HTC One M9 had a nano sim slot in it in order to connect to GSM 3G and 4G bands, which were not devloped yet in CDMA networks. if this is right, could I still use my GSM network through 3g or 4g?

Since LTE is a GSM-only technology there are not many "pure" CDMA devices, anymore. Nowadays, all CDMA phones support Sim cards and some GSM frequencies. However, that doesn't mean that you can get reception with every GSM carrier if you own a CDMA phone since different carriers use different frequencies. In addition, one and the same carrier might even be using different frequencies for its network depending on the location. You'll have to try out whether you can get mobile reception with your current carrier and that phone.
Assuming that no one tinkered with the hardware of that phone, you can find out its original MID by taking a look at the engraving on the bottom of the back side (c.f. the FAQ of the ReadMe thread).

actually the phone can read my gsm sim card, I have no problem with that except I want to make sure if it is CDMA version or not
I've looked everywhere in the internet but I didn't find a direct answers

Mhm... That MID belongs to the T-Mobile US (GSM) model. But your firmware is a CDMA one. The question is whether your phone still has its original backplate or not. Normally, cross-flashing GSM and CDMA will make the phone failing to recognize sim cards.
You could contact HTC and ask them whether they can tell you what kind of M9 you own with the help of its IMEI.

yes it does recognize my sim card
thank you very much for your help:good:
I'll try to contact htc to solve this contradiction

I'm facing same problem....
Dear Leo-pard,
could you please help me out....is your problem solved after chatting with HTC Customer care..
I'm facing same problem as my HTC M9 is also not showing Mobile Network Sharing Option....
Please help me out also....
I'll be waiting for your reply...

A lot of carriers charge extra for hotspotting. More than likely mobile network sharing will be off because the carrier wants you to pay for it. What I don't know is if it is coded into the firmware or not.

Hey @Flippy498
I have a sitting HTC m9 and like you said have missing mobile network sharing settings. My phone is s off with locked bootloader.
What can I do to use USB tethering it mobile hotspot? Can I use a third party app to use them?
Thanks

European HTC One M8 Not compatible with Honda

Hi guys. I've read several posts and have seen videos where the HTC One M8 is compatible with some 2013+ Honda's (Mainly Civic). I just bought a used HTC One M8 "International" phone. Using a "phone check", it says HTC_Europe, Bootloader 3.19.0.0000, Build MRA58K, Kernel Version 3.4.0-perf-g5022b24. I connected the phone via Bluetooth to my car and plugged it into the USB and it connects using mirrorlink, but when I click on the double arrows on the side, it says that the phone isn't compatible. I'm wondering if it has to do with the phone being a European version or something else. Can anyone here help?
I have also read that if the phone is S-off, it will not work with the Honda Head units. I restarted the phone while holding the volume down button and it says " ***Software Status: Official**** ***Unlocked***. Does that mean that mean that is S-off?

After fiddling around with it some more, I locked the bootloader and it worked perfectly on my car. I guess I had read that the bootloader needs to be locked, and not S-on or s-off. I have S-On btw. Just posting this up in case anyone else has this similar problem.
