For example to support the AWS band (which T-Mobile uses and almost nobody else), or the different set of LTE bands. You will also need a windows PC (or virtual machine) if the only suitable one we can find is a. One thing you should know is that running an RUU will factory reset the phone, so back up before doing it.

I'm going to be offline a lot of the rest of the day, so won't be replying instantly, but I can advise on how to use an RUU once we loocate a candidate (sites like still have a selection of M9 RUUs, it's a matter of finding the right one).

I can't guarantee we'll be able to find the right RUU, but if you give us what information you can about the phone and its software we can have a go. If the bootloader is unlocked you'll need to use a computer program called 'fastboot' to lock it, in which case you can also use it to get the cidnum, but we'll come to that later. an operator logo when you boot up, that would be good to know. I'm not sure that the software version you've quoted is enough, so if you can copy any other software information on the white bootloader screen or the system settings (software version, build number, baseband version) that would be helpful. So we need to find one that matches your phone. You also cannot use them to downgrade software. The catch is that these things will only run if the 'customer id number' (cidnum) of the phone matches what the RUU expects - basically what region and/or what network was the phone originally sold to.

To return the phone to fully official firmware you need to use a HTC package called an RUU (ROM Upgrade Utility). If all of those things are as I say they should be, then I don't know why it's telling you what it says.

If it says 'S-Off' that means that the NAND security flag is turned off, which probably indicates that it was modified but occasionally one leaves the factory in this state (no idea how or why) - this won't stop you updating, so don't worry about this one (indeed I'd advise not trying to change this unless you are very sure that everything on the phone is in its official state). If it says 'Unlocked' or 'Relocked' rather than 'Locked' then someone has unlocked the bootloader, probably in order to modify the software.

If the software status is anything other than 'Official' that is your problem. At the top of that you should see 3 pieces of information: 'Software Status: Official', 'Locked' and 'S-On'. If you get a black screen with coloured writing ('download mode') select 'reboot to bootloader' using volume keys to navigate, power to select, and that should take you to the white one. You should get a white screen with some coloured writing. Reboot the phone and hold the 'volume down' key down while it restarts (I think it's volume down, it's been a while since I fiddled with a HTC). The next simplest is to go into the bootloader. Unfortunately if it does not that does not mean that the phone is unmodified: they may have failed to achieve root, or attempted to undo it, or have 'hidden' it from the root checker, or have made some other change. If it reports that the phone is rooted then that means that the software has indeed been modified. So a very simple thing would be to download a 'root checker' app from the Play Store. Normally when people modify phone software it's in order to gain administrator access, which is known as 'rooting'. So the first thing to do is determine whether that is the case. The message is saying that the system software may have been modified, which is possible if it's a second-hand phone (you don't know what the previous owner did). Its warranty expired on march 26th of 2016'. Informations about my phone from HTC support : So, this IMEI is related to an HTC One M9 manufactured to be used in USA with the carrier called T-Mobile.
