    Hi,

    So short and simple:
    I have a HTC one M8; I am new to all this and tried to manually unlock my HTC so it would accept any network. I used the Squabbis toolkit and followed various instructions on XDA. I managed to get through all that successfully and my device showed unlocked and S-On on my boot menu.

    I was today playing around on my HTC recovery menu as my phone would still not connect to a mobile network; I could get internet data connection etc but not messages or calls. This is when I assumed the phone was bricked so I again went online looking for a solution; I saw the instruction to wipe the dalvik cache which I managed to do; but then I turned my back for a moment and my 2 year old bless her had gotten hold of my phone on recovery mode; I don't know what she pressed but now I am stuck on the HTC screen whenever I try to turn the phone on. I have tried soft reset, factory reset, power down but nothing!

    I think the phone was initially on 02; I bought it from gumtree.

    I have no idea what to do!

    Welcome to the forum - just sorry it had to be in these circumstances.

    Firstly, I think you've been confused about unlocking. There are 2 types of unlocking: "network unlocking", which is what you wanted, and "bootloader unlocking", which is a step towards "rooting" the phone, i.e. modifying the software to give you more control of it ("root" is the system administrator account in linux, which Android is based on). Unfortunately Squabbi's toolkit is for the second of those, not (as far as I know, though I've not read it in detail) for the first.

    So, you say you were looking at your "HTC recovery", but I wonder whether it was the HTC recovery, or a custom recovery that had been installed when using the toolkit? The reason I wonder is that the original HTC recovery cannot do very much, and I doubt it could easily get your phone into this state. However a custom recovery (ClockworkMod or TWRP), which is designed to back up your OS and replace it with a custom version, could erase your operating system completely if misused, which might explain your current predicament. If the OS has been damaged a factory reset won't fix it - all that does is erase user-installed data (the phone doesn't waste a couple of GB of storage keeping a spare copy of the OS just in case you do something that the original software won't let you do). The only solution if that is what's happened would be to reinstall the operating system.

    So, things you can do: firstly, confirm what recovery you actually have. When you enter recovery mode what does it look like, and especially does it have "clockworkmod" or "twrp" written anywhere? If it's a custom recovery one option would be to download a new OS (a "custom ROM", stored as a zip file), copy the zip to the SD card, then use the custom recovery to install it. If this interests you I'm sure that someone can suggest one (if in doubt I expect ViperOne M8, Android Revolution HD or MaximusHD will work, all of which can be found at http://forum.xda-developers.com/htc-one-m8/development). We can give more detailed instructions if you need.

    If not, or if you prefer to use stock software, you can use a package called a ROM Upgrade Utility (RUU) to completely reload the software. The catch there is that only some RUUs will work with your phone, depending on what software version it has and what network it was originally sold through (which you think is O2). A quick search hasn't turned up an O2 RUU, but I'm not an M8 specialist so maybe someone else will be able to do so (either here or in our M8 forum).

    Sorry if that's a bit dense - I have to go offline now, so tried to dump all my thoughts in one post.

    Hi Hadron,

    Many thanks for your reply. You are correct in assuming it was a bootload unlock; I quickly realized that is what I had done to the phone.

    I have attached a picture of the menu options I get when entering recovery mode.

    I will certainly try downloading the new OS and see where that takes me.

    Thanks,

    Yes, that's TWRP (Team Win Recovery Project), a custom recovery. If it was in the "wipe" menu when the little one got hold of it it would be really easy to erase something important.

    The custom ROM route is probably simplest way from where you are (though I'd charge the phone a bit before trying to install). Look for the thread for one of the ROMs I named in the XDA section I linked. I picked them as they are all reliable developers. It should be as simple as download, copy to the phone's SD card, select "install" from the screen you show in that photograph and answer any questions the install script asks. You should also do a factory reset before installing the ROM, but you've already done that anyway. There will probably be installation instructions in those threads anyway, but that's basically the procedure.

    Good luck!

    Ok. I will try the custom ROM install from the list you gave me.

    Thank you so much!

    I will charge the phone up tonight and do it tomorrow and will let you know how it goes.

    Thanks again,

    Christina

    Hadron,

    I installed the custom ROM as you instructed and it worked! I can't believe I managed to do it on my own.

    I installed a stock ROM I think it was called Marshmallow or something :)

    Thank you for saving my phone!

    Christina
