Help with SIM unlock & more help.

Hello this is my first HTC device and I just learnt about Hboot, Firewater, S-off, and RUU terms.
These are my AT&T HTC M8 with 4.4.2 OS on it, Just had it S-off and Unlocked bootloader.
Can I know the following things...before flashing anything onto this
1-> Can I SIM unlock it using the Config.dat method as the device was not at all updated ?
2-> Changing CID to SuperCID grants me access to all RUUs but that's not needed as I will use customROMs based on Sense and AOSP right ?
3-> In order to flash and all I must be S-off I did it So now I can use ViperROM 4.4.4 but before that the viperrom page says need for an updated firmware >3 mines on 1.5, So if I flash any will the S-off goes away ?? & found this thread here for firmware updates but it says red text, can I know whats that ??
4-> How can I convert this device to a fully unlocked device like dev edition/ international version ?
5-> Most important of all what makes this device go hardbrick and S-on again (Firmware flashing, RUU etc, Like to know what will cause this since the device is S-off can I assume this device won't brick like Nexus phones).
Sorry for this lengthy post, never used a HTC device wanted to make sure all is well.
Thanks :fingers-crossed: !!

S-OFF allows you to do all sorts
I used the Sim unlock method after i S-OFF my At&t device just because and really couldn't tell you if worked cause I actually like At&t .
Supercid does allow for flashing other gsm firmware/ruu
Yes you would want to be as close in firmware to gain the best running experience when flashing Roms above your current firmware
S-OFF only changes if you do it the way you gained it
Being S-OFF you could flash the wrong ruu and hard brick your device ( CDMA device hardware I believe could brick your device along with the wrong device kernel could also brick it )
Nexus is pretty solid but can be bricked

Thanks for the quick post :good:
So I will go ahead and update the firmware w.o redtext (just noticed it's the one that says "This build blah blah" when bootup) then I'm good to go for the flashing all stuff ??
I can also flash a non sense based rom after using sense based Viper ROM / ARHD / etc without any issues, now is my device basically a Dev Edition plus the RUU & CID editing is only needed If I ever need going back to stock (though it wont happen) or flash regional firmwares or converting to GPE, DEV, WWE editions rt ?
Lastly my device ID it says M8_UL_CA will it change after I flash a ROM or Radio or Firmware ?

Yes, you can flash any ROM. If you plan on running GPE, you will need to convert back using a WWE RUU as GPE uses different sized partitions making the system partition too small to run Sense based ROMs.
Your device ID will change to M8_UL after flashing WWE firmware, but it isn't anything to worry about.

While GPE is a trade off for only AOSP, with DEV/WWE I can run any ROM based on Sense/AOSP i.e GPE & including the Lollipop right ?
So before proceeding I will update the Firmware first to a 2.xx or 3.xx then run an RUU based on DEV/WWE for conversion
Sorry for so many doubts, slowly learning about HTCs devices

So before proceeding I will update the Firmware first then run an RUU based on DEV/WWE for conversion & for the last If I need to run Lollipop I should flash firmware again for v5 base or the WWE/DEV RUU (I think the Dev edition had got the lollipop Update) has the Firmware, Radio packed with it ?

The RUU contains the firmware. No need to flash it twice. You could just flash the WWE firmware if you are on Sense right now. Mostly RUUs are used to fix devices that are experiencing issues, or for converting GPE/Sense.
Running the RUU wipes EVERYTHING, so flashing the firmware is preferable. The WWE 5.0.1 firmware should be out soon, but DevEd is out now. If you wanted to convert to DevEd, there are plenty of tutorials on XDA. I'm really not up to speed on running DevEd firmware.

Found this page for all stuff & this thread for conversion.
& what's this .401 stuff in the first thread ?
I'm ok with full wipe anyways so I can use the RUU or the other recovery way for the conversion right ?

401 is International WWE firmware. For example, my firmware version is 3.28.401.9 Verizon's latest firmware is 3.28.605.4
If you are okay with the full wipe, the RUU is probably the best way to convert, but the recovery method with stock recovery and stock nandroid would work too.

Thank you verymuch for clarification !!!
Will do the work tmrw, its 2AM here

I've been fully converted GPE and back twice and after successfully converting back to Sense this last time I chose the Dev edition backup and stock recovery method followed by the proper CID&MID to take the OTA update witch is now lollipop
So basically I now have a lollipop firmware to run with the stock GPE lollipop ROM and you bet it runs great

HTC One M9
Hello,
I wonder why the HBOOT is now called ABOOT with the One M9.. is it just because it`s new design.. or are there more changes that we should be careful with?
Thanks a lot

I think its mainly like the HBOOT on the M8, maybe only a name change, but i can't say, because i did not diff the files and i'm not really into digging into
bootloader images, i only do the needed edits and then i'm done.

Mismatched MID and CID
Hello. I just got S-off on my HTC one M9 Developer Edition in order to flash this firmware, but found (through getvar all) that my MID and CID are not the same. Why is this, and is there a way to fix it?
MID: OPJA11000
CID: BS_US002

Of course they're not the same it wouldn't be good for your device if they were.
MID: a combination of numbers, letters and/or additional characters that identify your the device (as for example a HTC M9)
CID: a combination of numbers, letters and/or additional characters that identify the country of origin of your device and whether it's branded and sold by a carrier or not.
For example the MID and CID of an european M9 which is unbranded and sold in Germany are 0PJA10000 (that's a zero at the beginning not an O) and HTC__102.
Edit: Both, your MID and your CID, are the correct ones for the developer edition.

Sorry

I didn't mean mismatched as in not the same, I meant as in unable to flash this firmware for that reason (that they do not match any provided MID or CID).

Ok, sorry for missunderstanding your post. Well, the x.xx.401.xx firmware versions are meant to be used on the international version of the M9 which can be identified by the supported MID and CIDs. You could change both IDs using fastboot commands but since the hardware of the U.S. variants is slightly different* I don't think it is a good idea to flash this firmware on your phone. In the worst case you might get a nice new paperweight if your phone is not compatible with that firmware. Besides I don't think it'll take too long until the official 1.40.xxx.xx firmware is going to be distributed via the OTA function of the stock HTC rom.
*Blame the fact that U.S. carriers use the CDMA network standard while most other parts of the world are using GSM.

Isn't it GSM?

Last I checked, only Verizon and Sprint are CDMA. Does Developer Edition include that functionality?

Seems like you're right. As far as I read the developer edition is almost the same as the AT&T version which uses GSM. I thought every U.S. carrier uses CDMA. Nevertheless there must be a difference since your MID differs from the international one. If the hardware were the same there would be no need to use a different MID. Of course you could try installing the 1.40.401.xx firmware using the commands in the hide box but I cannot garantee that it will work or that your phone is still usable afterwards. I would actually suggest you to ask here whether you won't brick your phone by flashing the x.xx.401.xx version.
Code:
fastboot oem writecid <input desired CID without "<" and ">"here>
Code:
fastboot oem writemid <input desired MID without "<" and ">" here>
Edit: Seems like it won't "hurt" your phone to convert it to the international version.

developer editions on GSM
Hi all
i am wondering if the 1.32.617.30 developer firmware and RUU stuff will work on a GSM phone or more to the point a European phone.
The phone in question is mine it is unlocked and s-off and on super sid i just wanna make sure i still get phones call and stuff
any help or advise would be great
thanks guys

Hi thabks..is there any release date for the internatuonal 2.10 ruu??

Hi guys, need help here
I relocked my M9 and make it S-ON. im using firmware 2.7.401.1 I cannot install from any RUU, it seems there is no RUU that match with my firmware. I make mistake should S-ON the device later, but i already did it, so now i cannot use the phone because there is no OS on it.
I try to unlock bootloader, and cannot retrieve the token when using fastboot oem get_identifier_token. I read that since 5.1 you need to turn on unlock option in developer options, but i cannot do that, since the OS is already wiped
Is there any solution for this ?
Thanks.

when will we have the ruu zip 2.10.401.1 so we may be able to apply the SDCARD method to have a full clean stock flash?
I would like to have flashed in this way instead of going all the hard way in flashing ruuzip stock 1.40 and then upgrading by ota´s.
Thanks for all efforts, Nepht Legion.

Hi All,
Apologies if this is the wrong thread to post this in, just wanted to find out if anyone else has tried to manual install an ota on a M9 s-off.
I copy it to my SD and select to install it via stock recovery. It checks the file and starts the update and not once have i spotted an error, but once it is back up and running android, it is still on the old version.
I'm currently trying to go from 2.10.401.1 to 2.10.401.180, and if I go to aboot, it actual says the new version, but the OS version is still the old.
I would seem that the system partition isn't being updated.
Is there something i'm doing wrong? I tried the usual, googling and searching xda, but haven't found a solution yet.
Thanks

Rom flashing issue - How to go to MM without S-OFF

Hello all,
Sorry if this seems obvious, I've lost several hours looking for an answer and where to download the correct ROMs/right actions to do.
I use to have Android Lollipop on my phone (ARHD, dont remeber which version) and I tried to install ARHD 20.0 (MM) yesterday.
Manage to upgrade TWRP to 2.8.7.0 and manage to flash the ROM.
But, as mentioned in a very close post, MM firware isn't compatible.
Phone now stay stuck on bootloader screen.
I tried RUU update but it didn't work (bootloader is unlocked)
I then tried to lock my bootloader but fastboot/adb can't detect device (also went from W7 OS to W10 OS...) no clue why...
It seems I can't enter Fastboot mode (doesn't show on the screen, maybe it's normal).
And adb doesn't detect device properly.
Phone is S-ON so can't flash firmware directly.
Heard I should go back to ARHD14.0 but can't find any download link.
So here I am asking for help

That TWRP version is not recommended for latest rom versions. Use the latest one (TWRP 2.8.7.1-CPTB-Beta-1).
You need the Android M firmware if you want to flash Android M Sense-Roms. With S-ON you need to wait until HTC distributes the update for you SKU (which it hasn't done until now as far as I know). Btw: The firmware version you're using is more than outdated. With that version your M9 is still suffering the infamous heat problems. Nevertheless since several sources (Llabtoofer, HTC UK) hint that the Android M updates might arrive during the next week I would recommend getting back to stock (here's the needed RUU; instructions how to flash can be found in my signature), updating your phone to the latest LP firmware but waiting for the official update before reflashing a custom rom or rerooting your phone.

Which version of the M9 do you have? Also, can you get into your custom recovery?

According to your firmware version and the fact that your phone is S-ON you own a HIMA_UHL (MID: 0PJA10000) which is branded by Orange France.

It's an SFR phone... Could it be Orange branded? Kinda weird.
But OK thanks

I don't know the relations between French providers but it's theoretically possible that SFR and Orange share the same firmware on the M9. Anyway the SKU 73 belongs to Orange France.

This is a duplicate thread....
But to be clear again....you cannot use m9+ roms for m9....
Wait for vodaphone OTA....or get s-off and update firmware....same answer as in the previous 5 threads you've started asking the same question....g

I am s-off I wanted to know what to do to update the firmware do I change my cid from Vodap001 to HTC_01 then get the firmware for that cid no or can I just put a dev edition firmware I'm not sure and I don't want to mess up but yes I-am. S-on now sorry if I didn't make myself clear I want 3.35.401.1 firmware and the any custom Android 6.0 rom is that correct or can I copy backup of my other m9+

Convert to dev edition firmware and flash the rom of your choice...
Just follow the dev conversion thread and you'll be good...
S-off is nice huh ?
Happy flashing....g

That's usually means the MID is wrong for the software region that you have.
As yours is a S-Off device, I would say it is easy to fix it.
First thing .. we need to know what the MID is. Run this command - fastboot getvar mid
If you need the driver & tools for this - http://forum.xda-developers.com/showpost.php?p=64926362&postcount=4

Thank you very much for such quick reply.
I ran the command and it gave me
mid: 0P6B10000
I am from India and I want to get OTA updates in future.

Your MID is a EU MID
You can change it to India MID if you want to but it's a bit complicated for you I guess as it will involve change of MID, you may need to unlock bootloader & etc but it's not difficult.
Anyway .. for a start, make it totally EU version by flashing a Marshmallow EU RUU .. you don't need to unlock bootloader and you don't need to change MID. You will still can receive OTA if there is one but I think there will be no more OTA updates as M8 is already on its EOL (means no more HTC further support)
What you need to do :

option 2 : http://forum.xda-developers.com/showpost.php?p=66271711&postcount=4
either one should be fine for your device.

I don't think there will be issue as we notice most custom ROMs are based on EU ROM and many users from India are using them.

I'd recommend updating all the firmware (which in addition to hboot also includes radio, WiFi, Bluetooth, and a lot of other important modules) not just hboot. Being on hboot 3.16 means all your firmware is outdated, as in 2 years old. Updating to current firmware is best for compatibility with current ROMs.
You can either update by RUU (as discussed above) if available for your version. Or return to stock ROM and recovery, and update OTA (which will update the firmware). But we'd need to know more specifics about your device, to give more detailed direction. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

I have the same problem with my htc m9. I cannot do these processes as I am not a professional and don't have a computer .I have a doubt ,If it is the problem with region ,Why can't we simply changes the region by turbo VPN and try to update the Android version

You can't do that, since for HTC devices the region has little or nothing to do with spoofing where your phone is located (with VPN, etc.). The model ID (MID) and carrier ID (CID) are encoded into the phone. You typically can't change this on HTC devices, unless you have s-off. But further advice would be specific to the M9, and you should either search or post the M9 device forum. Following advice for a different device (this is for M8) is dangerous and can damage your phone!
