Hello guys,
I have my M8 bought from US, Verizon and I am living in Netherlands. The problems is that I cannot get the updates from Verizon because as you know is CDMA so I have been trying to find a way to convert my M8 Verzion into an international M8.
First step: I flashed @Mike1986's One_M8_2.22.401.4_odexed and everything workes on my phone, even wifi and I also receive notification about software updates, the only problem is that when I try to install that updates ( see the error in the attached image).
My question is : what do i need to modifiy to make the phone 100% international version ?
I have to mention that I have S-off already
Is your network carrier a cdma or gsm network? If it's gsm network, it will not work.
It's gsm.
Yes I read that it won't work if you are on a gsm network it will not work but technically Verizon M8 has the same hardware as the international version so logically it should be possible to convert it, I just don't know what do i need to do.
"logical" or not, the internal electronics are different in the radio section, so you will not be able to get it to work as you would like..

I don't know much about Verizon and I maybe wrong but if it is a GSM and S-Off (as you mentioned that you flash mike's ROM and it works flawlessly and you received OTA) then what you need is the right combination of CID and MID.
For e.g an Intl GSM EU_WWE, the MID is 0P6B10000 and for CID you can make it SuperCID.
Check your current MID - command fastboot getvar mid

That's explained the error that you posted in your screenshot because the OTA expect that you have MID 0P6B10000
You can change MID as in this guide : http://forum.xda-developers.com/showthread.php?t=2708581
The only question is whether the conversion will really work or not. I have no idea about verizon so not so sure. I only assume it will work based on your own comment that said Mike's ROM works flawlessly on your device. If this is true, then it should work.
Damn...it's really late over here ... gotta go now... maybe someone else have better idea for you ... good luck

You'll need to change your MID if you're trying for International WWE.
enter the following:
adb shell
su (if needed to get a # prompt)
Code:
Code:
[B]echo -ne '\x30\x00\x50\x00\x36\x00\x42\x00\x31\x00\x30\x00\x30\x00\x30\x00\x30' | dd of=/dev/block/mmcblk0p5 bs=1 seek=16384[/B]
(the above is one big long command. make sure you copy it all,and dont get extra spaces when you paste it.)
exit
adb reboot bootloader
fastboot getvar mid (or getvar all)
verify 0P6B10000 for modelid
fastboot reboot

Thanks, I changed MID, I will try now the software update to see what happens, I will be back with a reply
Hello everyone, I I just got an M9 at my local Telus store and I would like to be able to do everything with it like I am able to do with my M7, so I know I will need to use sunshine to get S-OFF and I would also like to be able to change everything from the rom to the kernel to the OS, everything, so I was just wondering if someone could let me know the best order to go about doing things, meaning should I do sunshine first then worry about flashing a recovery and all that, or should I do the recovery first so that I can backup the phones current state? The phone currently says this in the hboot screen:
*** LOCKED ***
LK-1.0.0.0000
OS-1.32.661.6
and this is what it says on the phones Setting-About-Software screen:
Android version
5.0.2
HTC Sense version
7.0
Like I mentioned before, it would probably be best if I can make a backup of the phones current state just in case there are any issues, so to do that I know I need a recovery, but do I need to do the HTC Dev unlocker before I can do so? or do I have to flash a recovery first before everything else?
Now, before anyone gets upset with me for asking these questions because they have most likely been asked 1000 times before, I am not asking to be spoon feed all the details step by step, I am just asking to be pointed in the right direction and asking for you guy's opinions on the best way to go about doing things so that I do them right the first time... So if anyone could please take a minute to help me out and get me pointed in the right direction then it would be greatly appreciated... thank you very much...

First thing you should do is unlock your bootloader. After that you can install twrp and flash supersu (most can be found here) Once you are rooted run sunshine. After that the sky is the limit. You will be free to flash anything and everything. I know because I've done it. If you want to convert to a developers edition there is a post here. Personally I do not use my stock recovery or system image backups to download ota's. I prefer to run an RUU and do fresh installs. Reason why is because I am constantly changing firmware and roms. A lot of roms are based on the WWE firmware.
let me know if you have any more questions

Thank you very much for the tips.. Do I use the HTC Dev website to unlock the bootloader? I seen a link in the dev thread that said Unlock bootloader without HTCDev(root required), but I bet that the HTCDev way is probably the best best. which did you use? I'm not at home right now so I will begin when I get home later on tonight and if I need anything else I will post back, plus I post back to say how everything goes.. Thanks again for help, it is very much appreciated...

I've used htcdev for all 2 out o 3 of my m9's. third one is a developer edition so it wasn't needed.
just note download mode is fastboot mode on the m9. htcdev says to boot to fastboot mode and if you do not know than you can waste hours trying to figure it out.

Ok so I got the bootloader unlocked and TWRP installed, right now I am taking a backup of the phones current state just in case. Now I just need to flash the SuperSU beta from the link you provided and then run sunshine, after that I would like to flash the latest OS for my phone, but I am not sure which version to use, I think this one is correct http://forum.xda-developers.com/one-m9/development/firmware-red-t3097678 but I am not 100% sure, do you know if this is the correct latest version for my phone?
Also should I supercid my phone before updating the firmware by entering "fastboot oem writecid 11111111" while in download mode? because my cid is TELUS001 and I do not see that cid listed in the androidinfo.txt file that is in the firmware zip...
Thanks again for all your help...
**UPDATE** I now have S-OFF, I can't believe how smooth the whole process is now with sunshine compared to almost all of my other HTC phones, hats off to those guys for sure... Thank you very much for getting me this far!!! I appreciate it very much...

I was actually just going to tell you to type
Code:
fastboot getvar all
while in download mode and to copy and paste that into a file a text file somewhere so you always have it. then you can supercid. I actually have never seen any firmware for your carrier. what is your mid? this is where I get all of my firmware from. I learned how to remove the red text using hex editor and I also throw in a custom splash screen before I flash.
Here is a link for your stock firmware. not sure what the most up to date is but most custom roms are using the WWE firmware anyways.
p.s. either quote me or tag me if you need a faster response. I'm not getting notifications otherwise.

My mid is 0PJA11000 but the one that is listed in the androidinfo.txt file of the firmware that I linked earlier is 0PJA10000, does this mean I cant use it? in all I plan to flash ViperOneM9 3.5.0 for the rom and it says it requires 2.10 but my phone is currently at 1.32

I honestly don't know if the hardware is any different but it looks like your mid is the same as the dev ed. check this one out. @clsA is very knowledgeable on the m9. I learned a lot of what I know from his posts.
Personally I have gotten so relaxed that I just change my mid and cid to whatever it is I want to flash and just go for it. But I also understand that I'm risking a brick by doing so..lol

took a look at the thread and it looks like all I need to do to flash 2.10 which is the international version is type fastboot oem writemid 0PJA10000 while in downloader mode because like you said and which I also confirmed in the other thread that my phone is the same as the dev ed and I should be able to switch back and forth with the same command

If going to dev ed I have had better luck running an RUU and accepting ota's as far as the radio goes. my reception went from 2 bars to full bars doing it that way verses just flashing the newest firmware. But it is a very long and tedious process and since you just got your m9 I'm sure you want to use it already..
What rom are you thinking about flashing?

do you know where I can find the latest international RUU? what rom are you running now?
@bigp951
Ok so I got the firmware updated to the latest international version 2.10 and was able to flash the ViperOne Rom and I love it just like I did for my M7... Everything is working great, except I have the problem that you mentioned would happen, I only show 1 bar for my signal strength, could you please let me know exactly what you had to do to fix it? Also, I would just like to say thank you once more, you helped me out a great deal and you made my upgrade to the M9 an absolute cake walk, so thank you very much for everything and for explaining the proper steps to take, I appreciate it very much...
Hello guys!
I just got my M9 last week (better late than never). And I have a two questions:
1. Since I already changed the stock ROM to LeeDrOiD One M9, will I be able to get the upgrade to Android 6 when it rolls out without flashing a RUU before and getting the upgrade through a HTC OTA ?
( If I understand correctly, it is important for the device to be updated with a proper OTA from HTC, because it prepares other sectors of the device for the new Android version, so a simple ROM flash will not help in that regard.)
2. I would like to have a RUU saved on my PC "just in case". I do not have S-OFF, and to be honest, because I just learned I need to pay for it, I don't think I can justify the cost (yet at least).
My phone has the following:
MID: 0PJA10000
cidnum: HTC__032
Anyone could please point me in the right direction about where to download a compatible RUU for my device ?
Thanks a lot in advance for your time reading this.
Cheers!
I think you have to go s-off.. There are guides in the m9 general section.
I wish I stole my HTC M9.
Many RUUs can be found here for free: http://androidruu.com/?developer=M9
Or here for a cost: http://www.ir-file.com/portal/index.php?dir=Firmware/HTC/HTC_Android/HIMA_UL/

Save $1.00/day for 25 days and you have enough for S-OFF.
@efrant
Thanks a lot for the links, exactly what I needed.

It's not a matter of not affording 25$ for a permanent solution to many potential head aches. But it is worth exploring any options before spending money.
Thanks for your answers
Well i have one htc one m8 from usa. Im in europe now. I need to change it to completely stock version. I dont really know whatbthat guy from whom i took the phone did on it, but im completely lost.
Its rooted with custom recovery and custom rom. I try many guides woth adb and staff and i fail.
If there is enybody who can guide me step by step will solve my problem.
Please help me.
First of all, there is a forum section for help and questions.
Secondly, what's the problem? You need to describe the problem (and provide specific details), if you want help.
Post more info, and I'll try to help; and also ask the mods to move this thread to the Q&A Help section.
Sorry about the thread on here and i beg mods to move it.
My problem is that i want to turn this mobile comepletely to stock version and ota updates.

What version? If it Sprint or Verizon, you can't convert it.
If its T-Mobile US or AT&T, you can.
Or some smaller US carrier version?

This statement doesn't tell us anything, and is close to useless.
What specific steps did you follow? What steps fail, or what is the specific result/issue?
You need to sort this out, since without adb/fastboot, you really can't do the conversion you want.

I don't really do "step by step" but I'll help. I leave it up to the individual to do the proper learning, so they can actually understand and gain some knowledge instead of just being spoon fed (and much of the info is already well explained in guides).
In general, you need to:
1) Get adb/fastboot working (you need to provide the proper info before I can help)
2) s-off with sunshine app ($25 US license): http://theroot.ninja/
3) Change CID and MID to the version desired: http://forum.xda-developers.com/htc-one-m8/general/change-wwe-m8-to-dev-edition-ota-t2826567
4) Run the desired RUU.
But as already mentioned, this depends on what version you have. Don't even try this with Sprint or Verizon. It won't work, and will probably brick the phone.
Its unbranded version not in belongs to any carrier as i search about it. The cid is WWE.

I'm skeptical of both those statements.
Unbranded US versions do exist, but are fairly uncommon. Its more likely a branded version, that has had its branding removed.
"WWE" is not a valid CID. Where are you getting this from?
You need to get fastboot working, so you can give us getvar data, so we can get the proper info on what version this is.
I have flashboot working. How can i see the proper cid?

You aren't reading very carefully, are you? "flashboot" isn't a thing. Please use the correct terminology.
Use the command: fastboot getvar all
The command won't work if you type "flashboot" :crying:

No you didn't (at least not successfully). The phone is still s-on. You skipped (or tried and failed) the step of getting s-off.
This step is not optional. s-off is required to change CID and MID.
But read more below, as I'm not sure you need s-off, or to change the CID/MID.
p00tin said:
My cid is like i said wwe. Htc_001
Click to expand...

First of all, you only said the CID was "WWE" which is just a description, and not an actual CID. You should have supplied the specific CID. WWE version has at least 15 different CIDs. When you ask for help, you need provide the info requested, and to be specific as possible.
Further, the CID as you typed it (Htc_001) is not correct. It needs to be in CAPS, 8 characters long, with 2 underscores: HTC__001
Most importantly, if the CID is in fact HTC__001, its already an unbranded Euro version, not US as you originally claimed. And if that is the case, you don't need to s-off or change the CID, MID.
Something doesn't seem right here. I need more information before we should proceed any further. You really need to do fastboot getvar all, and post the output (which I previously requested, but you chose to ignore). Be sure to delete IMEI and serial number before posting the getvar output.
I really need this data, before I can give you any further instructions.
There's something that I'm a bit unclear on when it comes to RUUs
Let's say that I'd like to try out the latest Marshmallow release without waiting for the OTA and use the HTC-provided RUU .exe (3.35.617.12)
I'm on a T-Mobile branded M9 and would like to keep WiFi Calling and Visual Voicemail. If I find that I am unable to use these features in the non-branded HTC MM release, will I simply be able to use the T-Mobile branded RUU .exe (2.11.531.19) to revert back or will I be unable to as it's an older version (Android 5.1)
I'm currently still locked and S-ON
I seem to remember downgrades not being possible on my M7 once the hboot was updated to a newer version, but am a bit confused about the specifics of the M9
Thank you, and my apologies if this is a dumb question -- I've done my best to find an answer through searching
You cannot flash RUU that does not match your device variant. In this case, you would need 3.35.531.xx RUU, to try marshmallow. 3.35.617.xx won't install on your phone, unless you S-off and change the variant CID.
But once your phone is S-OFF then you are able to downgrade, too. (Although it doesn't matter whether you use a RUU.zip or a RUU.exe.)

Well, now I'm a bit confused as far as variants are concerned. This HTC release page states
This software upgrade comes in the form of two sequential updates. The first update will install software version 2.11.617.180 , which does not include the Android OS upgrades. The following update will install software version 3.35.617.12 , which includes the changes to the Android OS.

Am I correct in understanding now that the '617' portion of those two versions is what indicates the device variant? And that my device's variant is '531'?
So then it appears that the only ways for me to try out Marshmallow at this point would be:
1) Wait until HTC/T-Mobile unleash their official release and update via OTA or RUU
2) Unlock my bootloader, flash TWRP, and install whatever ROM I please
3) Unlock bootloader, S-OFF, and RUU as I please

And so long as I'm S-OFF I could use this particular T-Mobile RUU executable to revert back to stock at any point and then re-lock my bootloader, correct? But as long as I'm S-ON, then downgrading is not an option, even using an RUU of the '531' variant?

Am I correct in understanding now that the '617' portion of those two versions is what indicates the device variant? And that my device's variant is '531'?

Correct. 617 is the SKU for the unlocked/developer edition and 531 belongs to T-Mobile US.

So then it appears that the only ways for me to try out Marshmallow at this point would be:
1) Wait until HTC/T-Mobile unleash their official release and update via OTA or RUU
2) Unlock my bootloader, flash TWRP, and install whatever ROM I please
3) Unlock bootloader, S-OFF, and RUU as I please

1) Correct.
2) You can't flash Android M Sense roms when your phone is using the Android L firmware. So you need to look for the Android L versions of the roms (e.g. ARHD 14.0 or Viper 3.5). Sense-less Android M roms like CM should be fine, though.
3) Correct.

And so long as I'm S-OFF I could use this particular T-Mobile RUU executable to revert back to stock at any point and then re-lock my bootloader, correct? But as long as I'm S-ON, then downgrading is not an option, even using an RUU of the '531' variant?

Correct (both times). Although you should keep in mind that your phone will bootloop if it's not 100% stock and you lock or relock the bootloader. (I personally think there is no benefit in locking/re-locking or even setting S-OFF back to S-ON unless you want to send your phone to HTC for warranty claims.)

Hmm, and here I was thinking that ROMS included the firmware and both could be flashed through TWRP. Guess I was mistaken. Or...

Phone was just purchased used, so if there's any warranty period left it probably isn't for very much longer. In the past I've gone S-OFF for all my HTC devices (Incredible, then One S, then One M7) but they've always seemed to have their own unique quirks and this M9 appears to be no different.
My main reasoning for staying S-ON/Stock at the moment is just in case I find a reason to return the device to the seller. After a few days when I'm sure everything is alright with it, I'm sure I'll be less reluctant to tweak.
Is a bootloop easily fixable?
So, to clarify (again!) --
In my phone's current state, I would be limited to Lollipop ROMs when flashing via TWRP?
So then, the shortest route to flashing custom Marshmallow ROMs would be to S-OFF and then RUU to an International Marshmallow firmware? Would I need to change CID manually or is that handled during RUU so long as I'm S-OFF?
And the safest route (in which S-OFF would be completely optional) would be to wait for the T-Mobile OTA release for Marshmallow before unlocking the bootloader and flashing TWRP?
Thanks a bunch for your responses. I'm sure this stuff gets answered all the time, but it can sometimes be difficult to find a specific answer in the depths of these boards. Plus, I find it hard to keep 100% on all development when I only buy a new device every couple of years.
I used the ARHD rom on my last device and quite liked it, but there was a T-Mobile specific variant that kept WiFi calling and all the other carrier-specific stuff. I'm pretty sure the developer has since long given up on maintaining those features., but it's my understanding that ViperOne may still have them.

The difference between rom and firmware.

Just reflash a RUU. The problem for most non-US firmwares is that HTC doesn't provide RUUs so sometimes there is no freely accessible RUU for a specific firmware version. (The only other method besides flashing a RUU is restoring a TWRP backup or re-/flashing a custom rom which needs an unlocked bootloader and TWRP.) If someone decides to re-S-ON and to lock/relock and the rom doesn't boot then that person might not be able to fix that bootloop without this RUU service. (The same applies to S-ON users who decide to relock if the rom doesn't boot.) HTC introduced a new security feature with Android 5.1 (firmware 2.x and higher). It prevents the bootloader unlock if the option OEM Unlock isn't activated in developer options. That's why I recommend everyone staying S-OFF and unlocked unless you need to send your phone back to HTC for a warranty claim since even OTAs can be installed with an unlocked bootloader. Well, RUU.exe deny to flash with S-ON and an unlocked bootloader but there are not many RUU.exe for non-US firmware versions and you can always extract the RUU.zip from a RUU.exe. (RUU.zip files can be flashed via an external SD card even if the bootloader is unlocked.)

Correct if you're talking about Sense roms.

Or you use an unlocked/dev edition RUU. There is no big difference between the firmware of those two M9 versions. Nevertheless you need to change both the CID and the MID. The commands are fastboot oem writecid <enterwhicheverCIDisneeded> and fastboot oem writemid <enterwhicheverMIDisneeded>. (SKU 617 - unlocked/dev edition - CID: BS_US002 - MID: 0PJA11000; SKU 401 - international version - CID: HTC__001 - MID: 0PJA10000; SKU 531 - T-Mobile US - CID: T-MOB010 - MID: 0PJA12000)

Don't know about ARHD but Viper has that feature.
Btw: Getting S-OFF is quite easy but it costs 25 USD. You simply need to use the Sunshine App. (Or you look for someone who has a java card.)
Thank you for taking the time to answer all of my questions.
No problem. Maybe those detailed answers might help other users as well. (That's at least what I hope. )

**** --
I changed my MID to the Developer edition, but I accidentally used the letter O and not the number 0 -- so OPJA11000
Then I attempted an RUU and now my phone is stuck in the RUU screen and I can't even turn it off. Is there any way to recover this? I don't even think I can use ADB anymore.
edit: I got it to reboot by holding BOTH volume buttons and POWER. What a stupid mistake. I'll leave this here though so hopefully no one else does anything so stupid.
Yikes :silly:
edit 2: Hmm, changed MID to the correct value but I'm still getting ERROR 131 CUSTOMER ID ERROR during RUU. Will have to investigate this further. Maybe I need to relock the bootloader.
P.S. The command to change the MID actually seem to be writemid, not changemid -- figured that out through trial and error
edit 3: Relocking the bootloader still gives the same error RUU. Now I'm stumped.
edit 4: Turns out the CID should actually be BS_US002, not BSUS_002, as you told me in the earlier reply.
edit 5: Yup, fixing the CID solved the problem

Ah, sorry. I don't know why I wrote changemid. It wasn't intended. Of course it has to be writemid. I will correct the post.

Sinc I don't know every CID by heart I copied it from a CID list I found with google. I'm going to correct that mistake, too. Thanks for clarifying.
Sorry for the hassle.

I didn't brick anything and got it all figured out in the long run, so no worries. I may not have attempted this in the first place without everything explained so concisely by you earlier, so thank you. Hopefully this thread (mistakes and all) can be beneficial to others.
Seriously though, who decided it was a good idea to put a zero before 'PJA' for the CID? That's just asking for trouble.
