    Are you running the command prompt in Windows? If you're a Windows user, please go to Start > Run then type cmd.exe

    Then, in that window, type:

    Code (Text):
    1. cd
    2.  
    3. cd C:\sdk-tools
    4.  
    5. adb reboot bootloader
    It should work. If not, did you install HTC Sync? You need drivers in order for it to work.

    I have a noobish question:

    I flashed the SU patch, nothing else. Everything seems to work great. What would be the difference if I flashed the odexed/deodexed Stock ROM instead? They're all stock ROMs, and I understand the difference between odexed and deodexed (waiting for a ROM that will require deodexed/s-off before messing with those options). What is there to gain in using the Stock ROM? Should I have flashed a Stock ROM and the SU patch?

    Please enlighten me.

    P.S.: thank you for all your hard work, this process was very simple and easy to follow. :).

    If SU Patch worked for you, and you have no problems, then flashing the ODEX version of the Stock ROM would have zero impact. The shipped ROM is an odex ROM by default. So those who are having problems getting SU to work or having issues with rooted apps would be the only beneficiaries of flashing the odex stock ROM, or they just don't want a custom ROM anymore.

    If you flashed the deodexed version, you would be able to apply any themes applicable to the stock ROM, but not much else. Odex ROMs are said to perform better, so you might even take a small performance hit. Although I've never seen any noticeable performance difference between odex and deodexed ROMs.

    Could you be more specific, please? At what step do you see this bad boot time error?

    It's something with the recovery I think. I have had it on two separate recoveries. Hasn't effected anything.


    In recovery it just says "bad boot - TIME error" near the bottom.
    It hasn't effected anything so I haven't spent time looking into it.

    If you didn't flash a rom, you have to flash superuser.zip.

    That part was left out of the guide.

    I did flash the SU, but it said installation aborted

    You need that for root. You may have a bad download.

    that was the 3rd one i downloaded, im flashing a rom with root already included so we will see how that works out

    did i do something wrong? i did everything right wit no problems. did the htcdev unlock trick with cmd/ect. installed the twrp recovery just fine. cleaned all the data/cash files.
    when rebooting it said andorid updating 49 files.. i did a root check and it asked for superuser request. i allowed. everything seems rooted. but i dont have a superuser app? like on miui or other Roms. oh and also i installed the SU patch on the defualt stock rom installed. i didnt want a custom rom. but i am rooted.. i guess thats all that matters right?

    I would either:

    1) Try flashing the SU Patch again, you should have that app

    2) Download SuperUser (or SuperSU) from the market.

    3) Download/flash the full stock odex ROM that has SU in it.

    The SuperUser in the app drawer is the SU app. You should be able to open that app.

    That's the problem I had. I was getting very nervous when adb kept saying it was writing recovery but nothing was happening, after 3 tries I re-downloaded recovery and all is well. Rooted with 4EXT recovery. Gonna hold off on s-off just because there's no real reason yet, did it with my Wildfire but until kernels ans such pop up root is all I really need to do backups and run root apps. Thanks for the guide!! Also props to HTC for supporting the dev community and providing the tools for unlocking the bootloader. For those of us coming from the Triumph we all know that the only reason it was so easy to root was because Moto didn't build the damn thing. To this day Motorola refuses us legitimate access to OUR hardware, leave that shit for Crapple not Android.

    i noticed i had this in recovery when i selected reboot after successful flash, didnt know what it meant so proceeded with the next step i believe it was the flash naowz step and everything else worked out splendidly......................
    many thanks to op i rooted successfully, took little over an hour but that was due to updates and re reading everything a couple of times before attempting, flashed odex rom and provided twrp 1.1 recovery, dl'd titanium checked for root and smiles there after, cheers, work in the morn so 4ext is for tomorrow

    thanks:D:D:D:D:D

    Updated the guide to warn about file extensions when renaming TWRP to 'recovery.img'. Hopefully that clarifies it for people :)

    I'm somehow lower than a complete noob... I got to the command prompt part but fastboot won't recognize my device, tried many different usb ports. (Computer is far too old for USB 3.0)

    edit:

    After a pc reboot, I get this once, then the above for any times after that.

    Did you install the drivers with HTC sync?

    Edit*

    Thanks I'm installing the drivers now. I just thought that meant enabling HTC sync on the phone.
