Htc m9 cant get the right RUU

when i turn on my htc m9 it goes to bootloader and i have access to download mode and recovery mode (rooted TWRP) and i tried with so many RUU but always i get error 131 (RUU not matched with your CID )
my phone is UNLOCKED and S-ON i cant get it to S-OFF and change the cid :/
kernel: lk
product: htc_himawhl
version: 1.0
imei:
version-main: 2.11.651.19
boot-mode: download
version-baseband: [email protected]

mid: 0PJA10000
cid: SPCS_001
any solution ? or RUU for my MID and CID ?

Have you identified your MID & CID? This will be key in finding the correct RUU. The best resource is the SKU/CID/MID list by Sneakyghost & Behold_this (url below). Yes, we could look it up for you, but it's best to learn firsthand and will take just a minute or two.
Once you know your carrier and model, we can start searching for the matching. From your information, it looks like you're currently on Lollipop firmware, so we're talking about moving you to Marshmallow if it's available. This will get you the latest firmware and enable you to run the latest custom ROMs, if you should choose to do so.

- a spreadsheet for using your CID & MID to identify your phone
HTC Sync Manager
- installs the necessary drivers & ADB tools for the HTC M9
Instructions for obtaining your CID, MID & software version on Windows:
a. Install HTC Sync Manager (this will install the necessary drivers & ADB tools)
b. Boot your phone into download mode (from a powered off state, turn on by holding the POWER+DOWNVOL)
c. Connect your phone to your PC
d. Open a command prompt window
e. Navigate to the ADB tools folder, typically C:\Program Files (x86)\HTC\HTC Sync Manager\HTC Sync
- assuming the path is correct, you can cut & paste this command into your terminal: cd C:\Program Files (x86)\HTC\HTC Sync Manager\HTC Sync
f. Execute the following command in a terminal (command prompt): fastboot getvar all
g. Copy the lines that mention product, version-main, mid, and cid.

@computerslayer: It's actually easier to look at the line with "OS" at the beginning which can be found in download mode (it states the same information as version-main from getvar all) and to search for a RUU that corresponds to that firmware version. There is no need for finding out the device's CID or MID.
Edit: Besides of that all the needed information can already be found in the OP.
@djope47: Visit HTC's US website. They provide RUUs for US carriers. The search function of your browser and your version-main will probably lead you to the correct RUU. Newer versions with the same SKU (the numbers behind the second dot in the firmware version and before the third dot) should be fine, too.
Edit2: Or you look at the RUU collections which are linked in my thread (located in the general section).

i got my firmware from HTC site (sprint) and in the begging of flashing (0%) it gives me error-155 (same result with unlocked/relocked bootloader and S-ON) and when i try with zip file it tells me i dont have the correct CID

So you tried the M9 x.xxx.651.xx RUU from HTCs website while your phone was relocked and booted to download mode? Your phone definitely has the correct Sprint CID therefore it's not normal that you face that error. How did you try to flash the *.zip from stifilz's collection (or did you extract the *.zip from the *.exe by yourself - if so: what have been your exact steps?)? Did you use fastboot or have you tried the SD card method described in my google sheet?
I personally don't like the *.exe files or the fastboot method (which actually work the same way). They fail so many times due to little mistakes a user can make. The SD card method on the other hand doesn't rely on working USB cables, drivers, the correct USB port, and a relocked bootloader (so you can use it with an unlocked bootloader, too) or in some cases the correct windows version (some people have problems with win 10 whereas the same setup with win 7 doesn't produce a single error for them).

ive tried the sd card method (go to download mode then press volume up button ) and i got the failed msg ,i tried it with different x.xxx.651.xx RUUs all gives the same result

Is it possible to install ruu from the US developer version to HTC One m9 bought from other country ? (Dubai version )

i found this https://www.youtube.com/watch?v=xWmnHwkDrKk ,its the same problem that i have but its for htc one ,ist safe if i try it on htc m9 ?

I didn't watch the video, but I can tell you that he is using an HTC One M7 and that I wouldn't follow instructions for anything other than your phone model (HTC One M9).

i noticed that all RUU.zip files that i downloaded are corrupted i cant extract them ,and the size of zip file is more than 2GB but the total size of the files inside it is like 70MB is this normal ? ive downloaded several RUUs and they are all with the same problem

They're encrypted and not meant to be unzipped. Therefore many programs can't handle those archives. If you use 7-zip and the #-method then you're able to unzip a RUU. However there is absolutely no reason why you should do that since they get flashed as a zip.

so what should i do ive tried what u said and didnt work out ! should i try this method https://www.youtube.com/watch?v=xWmnHwkDrKk ?? and in those RUUs they have the same CIDnum with my phone but the MIDnum mine is 0PJA10000 and the sprint RUUs have 0PJA20000
any solution ?

Oh yeah, I totally missed that. The MID with the 2 is the correct one for sprint. Did you buy your phone second hand? It looks like someone set is S-OFF, changed the MID and set it S-ON, again. Maybe that person flashed a RUU that's not compatible with that phone, too. You should try to find out the Serialnumber of the phone and contact HTC for finding out whether it really is a sprint phone or whether someone borked an international M9 (your current MID is the international one). GSM firmware and CDMA hardware are not compatible and vice versa. In the worst case it's unrecoverable.
If we know it's original firmware we might be able to fix the phone with a RUU. However I can't guarantee anything.
Btw, instructions how to flash RUU.zip files can be found in my google sheet, too.

I guess you're talking about the "100%" guide here in the general forum. The problem is that it only applies to the international version of the M9. Since many users don't know that there is a dedicated forum for every US branded version of the M9 mistakes like yours may occur.
If possible flash a custom rom that is compatible with your current firmware and based on sense (like an old viper version for example). Then get the sunshine app and try to re-S-OFF your phone. If you're lucky and the previous owner used sunshine, too, you won't have to pay. If not you need to invest 25 bucks to recover your phone. After you got S-OFF you change the MID back to its original state. Afterwards you should be able to use the RUU.zip as described in my sheet.

can't flash ROM or update

I recently got my hands on a One M9 but I'm having trouble updating anything on it. I check for updates and it says there aren't any available. However, my software version is 1.14.531.1, which is older than anything I've seen in any threads anywhere.
Here's the readout from fastboot getvar all:
kernel: lk
product: htc_himaul
version: 1.0
vzwisLTE:
vzwmid: HTC
max-download-size: 800000000
imei:
battery-status: good
version-main: 1.14.531.1
boot-mode: download
version-bootloader: 1.0.0.0000
mid: 0PJA12000
cid: 11111111
It doesn't say it here, but the phone is s-off.
I started by following the instructions at Cyanogenmod: unlocked, installed TWRP, installed ROM. However, it wouldn't install the ROM. It failed at the point where it tries to verify the device. I changed the recovery to the Cyanogenmod recovery and tried again, but that didn't work either. After a bit of reading, I thought that perhaps I needed to update the bootloader and that a RUU update might do the trick. I got the most recent one from HTC and ran it. It stalled where it says "sending" at 0%. I put the ROM.zip on the SD card to try it that way. That also failed. I relocked the bootloader and tried the RUU again with the same result.
I've wondered if I need to update the firmware per this thread http://forum.xda-developers.com/one-m9/development/firmware-t3068243 but I'm still new to the HTC world and not sure if that's it or if I'm just guessing. The firmware files I found there are much smaller than I expected, so I'm not sure what exactly they will update or if they'll fix the problem or just make it worse.
Can anyone tell me where to go from here, or at least point me in the right direction?

You can't flash offical firmwares unless your phone is stock. I think you should be ok flashing unsigned zips though. I couldn't tell you if htc do incremental or if you can just flash the latest. Flippy's thread might shine a light on something.. Your Cid is supercid.
Beamed in by telepathy.

So, are you saying that if I go back to the stock recovery that I should be able to use the RUU to update everything? There are a bunch of stock recoveries here, but none of them match my phone. The oldest ones there are several versions newer than mine and none match my CID. Can I still use one of them or do I need to find one that matches my phone exactly?

When I got the phone there was an SD card in it with a 0PJAIMG.zip file and a text file with a very long name with the software version (1.14.531.1) in it. Fortunately I saved them. I put those files back on and tried flashing that 0PJAIMG file and this time it worked. It seems to have removed the recovery I put on it and now it looks completely stock, with a locked bootloader and everything. Updating with the latest RUU still doesn't seem to work, however. It's still stalled at "sending" and 0%.
I would like to try a different RUU that's a smaller jump, but I haven't had any luck finding one yet.

OTA updates are incremental. A RUU on the other hand contains the whole firmware that has been distributed for its SKU until the point that RUU got released. Besides it contains the whole system. That's why RUUs are so big.
Sneakyghost's files lack some parts of the official firmware packs since they're not meant to get flashed if you want to get back to stock. They're meant to get flashed if you want to update your phone's firmware without reverting it's system back to stock since this way is less time consuming if you want to flash a new custom rom afterwards. That's why they're so much smaller than a RUU. Besides, they're unsigned and you won't be able to use them without S-OFF.
I personally don't like the *.exe versions of RUUs since they use fastboot and many users aren't able to set up their adb/fastboot environment correctly. Therefore, I neither support flashing RUU.exe files nor fastboot flashing of RUU.zip files. However if you extract the RUU.zip from the latest x.xx.531.x RUU.exe you could flash it via a SD card. I don't have a direct link to a guide for the extraction at the moment but there should be several here on xda which you should be able to find via google. It doesn't matter if they're written for an older HTC phone since the steps you need to do are always the same. Instructions for flashing a RUU via SD card can be found in my google sheet (which is linked in my signature).
And one last thing: The SCID prevents the M9 from installing OTAs. Therefore, you should revert it back to its original CID if you want to install any OTA.
Personal opinion: Since you can't use RUUs with a different MID than the one of your phone although you use the SCID (that was possible on older HTC phones) and you aren't able to install OTAs if you use it (that was possible on older phones, too) I personally don't think that there is any benefit left in using it.
Edit: I forgot to mention that there is a dedicated forum for the T-Mobile US M9 here on xda which can be found with the xda search function. You might find the files you need over there. Due to that other forum the T-Mobile US variant of the M9 isn't that much supported here in the forum for the international variant.

Thanks for the info on the T mobile forum. I wasn't aware of that and thought this was the only forum for the M9 here. I'll look for it.
I've already tried using the SD card method and that also failed.
I haven't changed the CID. It was the superCID when I got it. I don't think the previous owner changed it either because the phone seems unused. It still has the barcode sticker on the back and it's clearly be barely handled at all. The phone was originally a test unit or something because it has a serial number engraved on the front and it runs some HTC reporting software. It's rooted out of the box. I'm trying to replace the ROM to get rid of that extra software. I just mention that to explain why it's already rooted, s-off and superCID.

I would say the phone is modified. As far as I know, test units don't need S-OFF or the SCID since they simply use different firmware versions than normal units. You can change every version of the M9 into a test unit by applying for HTCs beta program.
What was the error that got shown when the SD card method failed? Did you try to flash the correct RUU.zip for your phone? As mentioned before your MID needs to match even if the phone has the SCID. Therefore, you can only use x.xx.531.x RUUs.
Edit: I forgot to mention that every S-OFFed device runs that reporting software you mentioned if that device is running the stock rom. That Software gets triggered by the S-OFF flag.

Well, I managed to find the 1.32.531.33 RUU in the forum for the T-mobile variant (thanks flippy498 for bringing it to my attention) and that ran just fine. Once that was done I tried running the RUU I downloaded earlier from HTC (3.39.531.31) and it worked fine. It seems the problem was indeed that I just needed something that was a smaller jump. I've seen no mention of any software version earlier than 1.32 anywhere in this forum, so I wonder if my phone was an early test unit or something that the version 1.14 mine had was an earlier pre-release version or something and that is why I had the problems I did.
Thanks for the info regarding the reporting software running on all s-off phones. I saw something about red text in other threads and wondered if that's what it referred to. Now I know.

After S-OFF can I go from 3.xx.yyy.xx to 4.xx.zzz.xx?

I've gone through the (extremely confusing) readme thread several times but would appreciate a concrete answer on dev edition conversion.
My phone is hima_ulatt / firmware v3.38.502.12 / OPJA11000 / CWS_001.
So my question is, once i:
unlock bootloader > s-off > write cid BS_US001,
can i install ruu 4.30.617.12 or would i have to stay within 3.xx.617.xx versions?

As far as I know you can't install a 4.x Ruu on 3.x firmware.

Download a 4.x based rom, there are several in the rom thread including the latest development rom.
They are stock ROMs that you can flash through twrp.
This one I've used and had no issues with.

Thank you!!

Please elaborate a bit further which part of the ReadMe thread confuses you. It's meant to be a helpful resource and if it's confusing at some point then it might need to get overhauled.
Flashing a rom won't update the firmware. Therefore, the linked roms won't help you much. (C.f. the article that is linked as "the difference between rom and firmware" in the further reading section of the ReadMe thread.)
You need to update the phone with an unencrypted firmware pack (that means an OTA or one of Sneakyghost's firmware packs). As already explained in this thread, RUUs with firmware 4.x use new encryption keys and therefore can't be used for updating from firmware 3.x. In addition, AT&T won't let you install OTAs on their branded phones if you aren't using one of their sim cards.
Either you convert to the 3.x version of the dev firmware and install the available OTAs afterwards or you need to flash a 4.x AT&T firmware pack from Sneakyghost's thread before you convert if you want to directly use the latest dev edition RUU.

I got confused too. It's confusing because the paragraphs digress and don't just follow the basic procedures. Probably because the information is necessary but not formatted into idiot speak.. idiot speak is what i needed.
So i thought "fk it my phone is dying anyway so how bad can it get"?.
If you're changing the cid and mid via fastboot do it first and get the firmware.zip of the region you want, at the phones CURRENT firmware level.
Flash the zip version of the firmware from external sdcard. To do that you need to
S-OFF: DONT NEED TO CHANGE ANYTHING.
S-ON: LOCK BOOTLOADER?? (CLARIFY)/CHANGE NOTHING?
rename the firmware.zip* file to whatever the filename asks for at the bottom of download mode (voldown+power), eg 0PJA***.ZIP.
copy it to the external Sdcard (not in a folder, just on its own), reboot phone to download mode, follow prompts.
THE PHONE WILL REBOOT MANY TIMES AND SHOULD TAKE AROUND 30 MINS TO 1 HOUR TO COMPLETE. DO NOT TOUCH THE PHONE. DO NOT TURN IT OFF. DO NOT UNPLUG IT FROM THE CHARGER. Leave it alone!!.
Once that completes you can take the ota.

Well, not everyone owns an SD card and there are other methods for flashing RUUs. That's why the RUU section describes all methods and the conversion guide only has a link to the RUU section. (The steps you describe are all mentioned in the guide for the SD card method.) This way users can choose which method they want to use. And describing all methods in both posts doesn't seem to make sense in my eyes, either.
The infos above the instructions of each post are actually needed for understanding why things are how they are if you've never owned an HTC device before. I can add a title "general info" for making clearer that the posts don't start with instructions, though.
The fact that you don't need to re-lock or lock the bootloader (neither for RUUs nor for OTAs) is e.g. explained in these additional infos. It's not mentioned in the instructions since that info itself is not an instruction.
Btw, a RUU reboots the phone only once and the flash shouldn't take longer than a couple of minutes. OTAs on the other hand can take up to am hour and reboot the phone several times.

Yes you are correct as always flippy. The reflash back to stock takes minutes while ota takes an age. Forgot that bit.
You also redefined what i said.. the posts digress to cover all eventualities but it is overwhelming to eejits like myself.
If it was laid out basic THEN cover the eventualities it'd be easier to follow. The english can be a tad broken too, which confuses the fk out of native English speakers like myself.
My post is just the basic. Nothing more, nothing less. If you bork your phone with my instruction it will be a hardware or user fault.
The only thing I'm not sure of, because my phone is s-off, is whether or not the bootloader must be locked or relocked with s-on. Otherwise with s-off they dont matter.
Don't get me wrong, I'm not saying you're feeding false info, I'm just saying that non native english speakers seem to have better results following your instructions better than native speakers, for some reason..

Thanks for the info @Flippy498. I'll be re-reading everything thoroughly before attempting anything as i don't want to end up with a brick.
The readme is indeed confusing. It captures the evolution of the m9 since fw 1.xx and the corresponding changes to modding procedures. While this makes for a great catalogue of all info, even a seasoned flash-o-phile would find it difficult to navigate the veritable minefield of do's and don't's.
I'd love to redo the logic of the thread myself but don't know enough about this device yet. but perhaps something that determines one's fw/mid/cid through fastboot first, followed by targeted instructions for achieving different goals based on those differences would be much more legible. (e.g. if fw v 3.xx, do this to unlock but warning about flashing 4.xx). As it stands, coming from v 3.xx, one has to read several disjointed notes peppered around the thread only some of which are relevant and this only adds to the confusion via information overload.

If you have s-off youre good to go in any circumstances. Just check the os that it is on and return it to stock of that version os OR
If you change the cid and mid just flash to stock of THAT version AND the region you change to. Like changing from 401 to 617 you flash the 617 because it matches the cid and mid you changed to. It must still match the os version the phone is on ie marshmallow 3.35.xxx.xx, making it the 3.35.617.xx firmware you'd be looking to flash to get stock marshmallow..
Then you just take the ota updates as far as you like.
I flashed 2 s-off phones back to stock in the last week in one sitting and it was easy, just as I explained.
It's just bootloader in s-on conditions that I personally don't know and that throws me a bit. I don't know if it's a requirement or not. I'd highly recommend buying s-off via sunshine in all cases but otherwise flippy would have to answer a simple yes or no to "bootloader locked for s-on flashing?" or you'd have to dredge it up on a search site. The other option is bite the bullet and flash anyway hoping it boots you out with an error.

Your method worked great! changed cid & mid to dev edition, flashed dev edition and then used 'software update' to catch up to latest version. couldn't be easier, thanks!
Now for that obnoxious red text...

I take no credit for anything. All I did was make the process clearer. Glad you're sorted!.

S-OFF, Bootloader locked - need help to get OTA updates

Hi folks, I've read the Flippy498's M9 ReadMe thread and understand most of it but still need a helping hand from you more experienced folk in order to update the software on the M9.
I bought a "like new" M9 a few months ago from a seller somewhere in Asia (Hong Kong I think). I know, bad idea, but I had a tight budget. The phone has lollipop - I've been happily using it in the UK but now a few apps I need won't install (apps to access work email etc. since lollipop isn't supported by these apps).
I know the phone has been tinkered with (S-OFF and supercid) - but I'm not sure why (to unlock?). I get an OTA update notification, but it won't apply (see screenshot). I've included a couple more informational screenshots below.
Bootloader locked, S-OFF
0PJA100 (this is written on the back of the phone as well - no reason to believe it's a frankenphone)
htc_himulatt PVT S-OFF
CID-11111111
LK-1.0.0.0000
RADIO-01.01_XXX
OpenDSP-XXX
OS-2.11.617.258
My situation might be similar to these folks, neither of who had any luck:
https://forum.xda-developers.com/one-m9/help/unlock-bootloader-android-6-0-software-t3741019
https://androidforums.com/threads/phone-wont-update.1157270/
I don't want root (banking apps fail). I might be wrong, but I think my work apps won't function with TWRP - rather not chance it.
I'd like to update the phone's software as simply as possible. (Note that the Ebay listing said that they recommend I do not update - not sure why)
Questions:
I'm aware that the CID is incorrect. If I change it to something else (what?) - will the update work? If so this seems to be the simplest method.
Is this a CDMA phone?
Is it possible that the phone becomes locked after updating? Right now I can use it in the UK and 4G works.
Would you recommend some other method? Like changing the CID and flashing an RUU (which one will work? I'm aware that version numbers need to match.)
The phone seems to default to Canadian English - not a big deal - would I be better converting it to another edition?
Thank you very much for any help/advice you can offer. I've rooted, installed custom recoveries and flashed loads of ROMS (on an S3 - nothing as complicated as the M9). If any further information is required I will provide this ASAP.

You didn't buy a CDMA device and your issue isn't similar to the ones you linked.
At the moment, there are two problems that are preventing your phone from being able to install OTAs:
You're using the SCID (11111111). Unlike on previous HTC models, OTAs will abort when they notice this CID.
Your current firmware doesn't match the system version you're using. The firmware that is shown in download mode belongs to the developer edition (SKU 617). The OTA on the other hand belongs to the Canadian Telus version (SKU 661). OTAs will abort if they notice such a mismatch as seen on the pic that shows your phone's stock recovery.
In addition to that, the firmware with SKU 617 actually belongs to the 0PJA11000 (hima_ulatt - a US model) while you own the 0PJA10000 (hima_uhl - the International model) according to the engraving on its backside. Since both are GSM versions and the differences are almost non-existent, cross-flashing is absolutely no problem, though.
I'd recommend you to follow the conversion guide that can be found in the ReadMe thread. Use one of the European RUUs that share the same decryption keys as your current firmware. (In other words a 2.x or a 3.x RUU for SKU 401.) Due to problem 2 you won't be able to solve your issue just by changing the CID. You'll need to flash a RUU for fixing that.
Since SKU 401 belongs to the unbranded European firmware you don't have to fear a sim lock or something similar.

Thank you Flippy498 - that's just the type of clarification I was looking for! I'll follow your instructions and let you know how I get on. (It might be a few days before I get the block of time I need to do this properly, but I will certainly feed back.) Thanks again.

Hi Flippy498 - just thought I'd check in and let you know how I got on. I followed your instructions exactly and everything is sorted now - I have a fully updated stock M9.
In the unlikely event anyone else finds themselves in this particular situation, and for reference - here are the steps I followed:
Installed a fully functional adb/fastboot environment as per the ReadMe section "Setting up ADB/Fastboot/HTC_Fastboot correctly".
Changed the CID and MID (as outlined here "How to convert your M9 to a different version": https://forum.xda-developers.com/showthread.php?p=71421945#post71421945). For reference the CID I used was HTC__001, the MID was 0PJA10000.
Used the 2.10.401.1 RUU (https://www.androidfilehost.com/?fid=24269982087011324)
Used the SD card method outlined in the ReadMe section titled "RUU Section"
Flash went perfectly. OTA updates all came through as expected. Job done!
Thank you very much Flippy498 - your explanation was crucial to allaying my fears of bricking the device, and giving me the confidence to go through with it. :good:

This description was very uselfull to me, this summer (July 2021) I purchased 2 brand new HTC One M9 in Sealed packages from a Danish auction house, they was both european phones, but both of them had the folloving configuration:
Locked bootloader
S-ON
Developer version 3.35.617.12
Supercid 11111111
MID 0PJA11000
I need firmware 4.x in order to use the latest Android 11 version of one of the following: crDroid, LineageOS or Ice Cold Project.
I could have lived with the developer version but the super CID 11111111 prevented me from getting to version 4.x
I did the following.
1) For the first phone I registered with HTC developer site in order to get the code to unlock the phone, later on I learned the Sunshine app also unlock the phone, much easier Also I did not need to root the phone because Sunshine App did that temporary, for 25$ this app did some very dificult stuff for me in an rather easy way.
2) From the RUU section I downloaded and flashed 3.35.617.31 on the first phone (still with S-ON) using the SD card method, because there was an OTA file that could bring me to 4.14.617.6, but the update complained about the Super CID 11111111, there was no way around it, I had to use Sunshine app.
3) The first phone I S-OFF'ed with Sunshine locked at the white HTC boot screen, I was unable to power it down, I reached out to support and they adviced med to power the device down by pressing all 3 keys VOL Up/Down and power for 60 seconds and then uninstall Sunshine app, reboot the phone and install it again, then everything went as expected.
4) Now I wanted to get to a 3.x version that will allow me to change to 4.x via OTA file
4a) for both phones I used the SD Card method
4b) for the first phone I had already flashed 3.35.617.31, now I changed the CID to BS_US001
4c) the other phone I changed to H3G__G04, MID to 0PJA10000, and flashed 3.35.771.12
5) Now I was reddy to get to 4.x version
5a) For the phone with version 3.35.617.31 I loaded the OTA file from SD Card to 4.14.617.6, after that I changed the MID to 0PJA10000 and the CID to HTC__001 and flashed a european RUU 4.28.401.3
5b) For the phone with version 3.35.771.12 I loaded the OTA file from SD Card to version 4.30.771.2
5c) For both OTA files I experienced that the script stopped at the last line before completion, I had to power off and run the OTA file once more, where both cases completed as expected.
6) now I have two phones that are ready to go to Android 11, I expect that I wil leave the one with version 4.30.771.12 with the original latest HTC version and keep it as a spare phone, the other one I will use to load Android 11 and Gapps
I hope the can be usefull to someone else in a similar situation.

Just can't get the Phone to work properly....help please..

Hi Guys,
So I have an M9 which I bought on eBay brand new from China.
It came with an USA Rom which had been tweaked to work in the UK.
Anyhoo, I unlocked the bootloader, S-Off using Sunshine, installed a recovery, Rooted and SuperCID it.
They I replace the Rom with the international Rom:
0PJAIMG_HIMA_UHL_N70_SENSE80_MR_HTC_Europe_4.28.401.3_Radio_01.01_U114401011_117.00.61117G_2_F_release_498151_signed_2.zip
I had to change my MID from 0PJA11000 to 0PJA10000 for it to work.
Well it all works beautifully except the Phone.
I am sure I have the wrong Radio for the UK.
The signal is weak and cuts out, I know I'm in a very strong signal area and all my other phones work fine. Indeed I had the same problem with my M8 until I changed Radios.
Now I have used (or tried to use) every Radio in this thread:
https://forum.xda-developers.com/one-m9/general/recovery-flashable-radio-zip-t3122983
But none of them stick, sure they go through the motions of flashing and even say they had finished (Using TWRP) but they don't actually change the Radio.
Currently my Radio is:
01.01_U114401011_117.00.61117G_2
Im in the UK and I'm on the O2 network so I need a Radio specific for that.
I downloaded this Rom:
0PJAIMG_HIMA_UHL_M60_SENSE70_MR_O2_UK_3.35.206.13_Radio_01.01_U11440792_93.00.51117G_F_release_464855_signed
But I get Error 12 whilst trying to install.
Do I have to just change my MID back to 0JPA11000?
If it's not that I'm at a loss as to what the problem is.
Here is my Getvar:
(bootloader) kernel: lk
(bootloader) product: htc_himauhl
(bootloader) version: 1.0
(bootloader) serialno: ***************
(bootloader) current-slot:
(bootloader) imei: *******************
(bootloader) version-main: 4.28.401.3
(bootloader) boot-mode: download
(bootloader) version-baseband: 01.01_U114401011_117.00.61117G_2_F
(bootloader) version-bootloader: 1.0.0.0000
(bootloader) mid: 0PJA10000
(bootloader) cid: 11111111
Please help me get this sorted, its such a great phone..
Thanks

Oh joy....
Well I've been up all night after soft bricking my phone.
Eventually managed to install the O2 RUU I wanted!!
Had to format a 8GB microsd to fat32 so the phone would see it even though the hboot said it was on 4.xx firmware.
I also couldn't write mid or cid, they wouldn't change.
Anyhoo formatted microsd copied RUU onto it renamed OPJAIMG and it worked!!
BUT NOW....
Well now I want the OTA which it downloads then says my software's not official...
So do I have to relock it, s-on it and unroot it for the ota or can I just flash it from somewhere?
All I know is I've got the correct Radio installed.
So that's good!
Any help from the Pro's would be much appreciated.

I believe what I will do is update the firmware in increments no-wipe using the firmware thread...it's got the correct O2 ones on there.......If only I could find it..

No that won't work...the firmwares are older than what I already have installed...
Anyone got any ideas?
I just want to receive the OTA really, how do I convince my phone its genuine?
OR
Where does it download it to so I can rename it and flash it? (Can I do that?)

Well guys I'm getting there, I have found the OTA on this site so am downloading now.
Hopefully that will be that and I can get some sleep!

Now I'm getting Error 12...
How do I sort that?
In the error listings 12 is not sure what it is...

So in my wisdom(!) I thought it couldn't make a giant leap from firmware 3 to 4.
I figured(!) It need the firmware in between.
4.14.617.6 So I downloaded that and whilst trying to flash it sdcard method I get error code 7
All I know is that the M7 and M8 were a lot easier to do!

My New Getvar:
(bootloader) kernel: lk
(bootloader) product: htc_himauhl
(bootloader) version: 1.0
(bootloader) imei: ************
(bootloader) version-main: 3.35.206.13
(bootloader) boot-mode: download
(bootloader) version-baseband: 01.01_U11440792_93.00.51117G_F
(bootloader) version-bootloader: 1.0.0.0000
(bootloader) mid: 0PJA11000
(bootloader) cid: O2___001

Well I've now changed my MID to 0PJA10000 and that's not worked even though that is the right MID and so I then changed the CID from the correct O2 one to Super CID which I believe is 8 1's...so 11111111.
But that hasn't worked...
What have I got to do guys, it's not this difficult ever, what's going wrong?
I know I'm not rooted any more and I don't have a custom recovery but that shouldn't matter or does it?
I hope this isn't one of those threads that just sits here...
Why I had an O2 UK RUU that gave me a MID of 0PJA11000 makes no sense if it's supposed to be 0PJA10000...and that one worked!!

I'm stuck as to what to do......

Well I've gone in a big loop only to end up with the international version back on my phone. Its the latest one, the O2 ones although they have the right radio are stuck on Lolipop or Marshmallow. They want to update but cant as my phone software is not recognised as official due to being rooted....
So I have the phone back up and running on WWE but the signal is dire.
If anyone can tell me how to extract the radio from the O2RUU and apply it to my phone it would be appreciated...if not I will just send my phone back to HTC and get them to do it.
I've never seen such scrappy out of date software.

I'll just start at your first post and reply to everything that catches my eyes since you already created that many posts in this thread. In general I highly recommend you to carefully read the ReadMe thread.
In general: Are you sure that you bought a GSM variant and not a CDMA one? These technologies aren't compatible with each other an flashing GSM files on a CDMA device or vice cersa always leads to headaches (worst case: unrecoverable hardware damages).
Post 1: It doesn't matter whether you use the unbranded 401 baseband or the O2 branded 206 one. The reception should be the same. (CDMA devices can't read their own IMEI anymore and lose all reception if you flash GSM RUUs on them, though.)
SCID isn't recommended to be used anymore. It prevents your phone from installing OTAs and it won't make your phone ignore MID mismatches with RUUs like it did on the M8 and older HTC devices.
Post 2: The M9 and all newer devices don't have an hboot, anymore. There's the download mode and the aboot which replace what you know as hboot from older HTC devices.
Never re-lock this phone or re-S-ON it unless you know for 100000000000000 % that it's absolutely 100 % stock and completely unmodified. There are security checks which will prevent the phone from booting if it's modified and you e.g. re-lock the bootloader.
Post 6: Error 12 indicates that you tried to flash a RUU with a different encryption key than the one your phone's current firmware is using.
Post 7: I haven't seen error 7, before. Since you already had problems with flashing the other RUU via your SD card while the SD card wasn't formatted to fat32 I assume it might indicate some SD card hardware issue.
Post 9: RUUs can't change your MID. That's something you need to do manually via fastboot commands.
Post 11: If the OTAs fail although you directly used a RUU beforehand than you're either using the wrong MID or an incorrect CID. The only other possible reason might be that you're suffering from the first symptoms of a nand death. Like all smartphones with the Snapdragon 810, the M9's hardware can suddenly die due to the hardware damages that get caused by the heat of the infamous processor.

Thanks Flippy, I learn so much every time I post here you are truly experts.
I will look at all my posts as questions solved by the last post!
I'm pretty sure it's GSM but would love to know how to check.
I have through chance, luck and what I thought was knowledge secured a good running International RUU....
I am rooted, unlocked, supercid and running beautifully.
Yet my Radio is wrong.
I try and try (this was the start of the post and is still the end) to try and install a new Radio.
When using the old O2 RUU it was clear that was the correct Radio.
An old one!
However I have not been able to flash any other Radio from the M9 Radio post.
This as you can imagine is a huge problem as much that we all like to use our phones as superfast little Chromebooks, they are first and foremost Phones!!!
If I cannot find a good Radio I must get HTC to sort it for me.
It would be wonderful if I could find a tutorial on how to pull the Radio from a firmware Rom as I have the old O2 RUU that has a Radio (all be it old) that suits my needs.
I've not been able to find such a Radio and unfortunately the RUU that would have been exactly what I was looking for turned out to be German and as such had the incorrect Radio.
I can't believe (but believe I must) that HTC UK do not support rooted phone and provide the software as they do for the USA....but there you go they don't.
They have however offered to "fix" my phone...i.e. replace the software...for a price I may add, rather than providing me with software and allowing me to do the 5 second operation for free...
That's where I'm up to Flippy, its kept me awake for over 36hrs and ruined my weekend.
Thank goodness for Bank Holidays.
May I add that the M9 is my favorite HTC so far, I have played with the SPV (Very slow but very cool!!) One X (Popular but over rated), One X+(great phone for the time), the M7 (Equally an excellent phone), the M8 (lasted me for years, amazing) and now the M9. I don't like the M10 because of the iPhone/Samsung One button and I haven't been privy to the U11/U12/U12+ but don't much rate anything you have to squeeze...let alone get a decent case for so your £700 (I can buy a car for that) phone doesn't get a scratch....at the end of the day a Nokia Dumb phone was good enough and a Laptop was a laptop.
I know it's going to progress to jewelry, glasses and smart clothes...then onto holographic VR and Thought(!) and Implants(!) but all I want is a phone that does a few things, first and foremost PHONE people!
God bless technology and God bless the back engineering from downed UFO's.
But technology and the concept of God doesn't sit right.
So thank Science!

As already explained in your other thread. There is no "German" RUU. HTC got rid of a whole bunch of SKUs with the M9. Several countries now share the same SKU (and therefore the same firmware) while only the CID differs. You were using the correct baseband after you had flashed the 4.27.206.4 RUU. Officially, it's even labeled as O2 UK RUU by HTC.
However, I took a closer look at the latest O2/206 and the latest unbranded European/401 RUU. Both use the exact same baseband/radio version. So whatever your issue is, it's not baseband related.

They never provided RUUs outside the US. And HTC even stopped providing RUUs for all of their newer phones. The HTC 10 is the latest model for which you can find RUUs on their US website.
Finding out whether you own a CDMA device or a GSM one can be quite easy if no one has ever replaced the backplate of the phone. There's a small engraving with the MID at the bottom of the backplate. If the backplate got replaced it's impossible to say which version you own, though. With S-OFF you can cross-flash GSM files on CDMA devices and vice versa after you manually changed the MID since S-OFF means nothing else than all Security checks being set OFF. And after cross-flashing, there's no way to find out which version you own via the software.

Thanks Flippy, very informative.
It's a new phone, came in a sealed box.
Marking on the back of phone:
Model: 0PJA100 FCC ID: NM80PJA100 M9u
I can't find what I need, so I will send to HTC.
I didn't want to root this M9 but had to as supplied with USA software. But have conceded and will let HTC deal with it.
Thanks for your time.

According to everything you described it's impossible that you bought a new phone. And I wouldn't trust a seller just because the device got shipped sealed. Breaking a seal and re-sealing the box at a later point isn't that difficult.
Assuming that the backplate didn't get replaced, the MID on the backside indicates that you own the international hardware variant. Without tinkering (in other words: without opening the box and breaking the seal) it's not possible to flash US firmware on that device.
And if we assume that the backplate indeed got replaced it's even less possible that you bought a "new" phone.

I might right it off then and go for a U11.
Will see what HTC say and yeah I don't trust the company I bought it from, once I unlocked it I was sure there was tampering......

Wwe works just as good as o2 firmware. Can you flash an m9u with m9 firmware?.

The M9u is the M9. The u only indicates that you're talking about one of the GSM variants and not about one of the CDMA ones (M9w).

Just been told by HTC that the phone is a counterfeit!
The IMEI and Serial Numbers just don't exist.
Thankfully I'm covered by PayPal who are now dealing with it, but really...!!!
First time in the 10 years I've been doing this that I've bought fake...
