Thank you!!

Decided to update the instructions for this fix.

Thx to sruon for the fix

Original instructions pulled from IEFtm's post @ Modaco



Tried using the 'manual' method but it was a no go! Just wouldn't seem to work. I know this post was from years ago but would highly recommend loading the update zip from the above link and installing it on your SD card (I have a reader). It also fixed the problem of my phone bootlooping unless attached to the USB!

    These fixes require the Android SDK and very basic ADB knowledge. You can copy and paste for most.

    Make sure in device manager the driver for fastboot is installed (Win 7 downloads them automatically)

    For USB fix

    Download the flash_image & mtd-eng.img attached, unzip them and put them on the SD card before starting


    SD Card Fix

    Press & hold vol down and power on the phone
    Select fastboot by pressing the power button

    ADB commands

    fastboot oem enableqxdm 0
    fastboot reboot

    That should fix your SD card not being detected.


    USB Fix * Root REQUIRED *

    Update - Some have reported that updating the radio fixes this, so if this guide doesn't work, try that

    Run from a terminal emulator in Android since ADB won't work if the USB port is not working

    Terminal emulator & ADB commands

    su
    cat /sdcard/flash_image > /data/flash_image
    cat /sdcard/mtd-eng.img > /data/mtd-eng.img
    chmod 755 /data/flash_image
    /data/flash_image misc /data/mtd-eng.img
    reboot

    And that should fix the USB issue

    Thanks for this mate. Worked like a charm... even with your files, I didn't need to muck around with the generator or a hex editor. I will tell you this tho, I dont ever wanna do that again. 10 minutes to type 5 command lines in a shell on an Evo sucks hard.

    In the middle of use today, my Evo suddenly announced that I had removed the SD card and warned me that I should not do so without powering down.

    I tried a number of different things to get it to re-recognize the SD card and have been thus far unsuccessful, the most annoying of which was selecting the manufacturer reset option in Recovery, which wiped all my data and some of my apps, but didn't fix the SD card issue. :S

    Plugging in the USB activates charging, the computer recognizes the USB drive but indicates that there is no disk in it. My 3 "Connect to PC" options are: Charge Only, HTC Sync, and USB Tethering. USB Tethering works, and HTC Sync won't find Sync on the computer....even though ADB devices does find the device.

    I found this thread and followed the instructions and fastboot indicated that all was happy - except that when it rebooted, I still have no SD access.

    I've checked the SD card on my computer, and it's fine - I just can't get the phone to recognize it at all, not via recovery, nor with Astro, or anything I've tried.

    Any thoughts on what's up? Since it just randomly went out in the middle of use, I'm worried it might be a hardware failure on the side of the phone....


    Using:
    Myn's Warm TwoPointTwo RLS5
    Supersonic EVT2-3 ENG S-OFF
    HBoot 0.76.2000
    Radio 2.15.00.11.19

    Happened to me as well. I had to back up my card to my pc and format it to get it to work again.

    Can you be a little more detailed? When restart my Evo holding the power and vol down buttomn I see an option for Fastboot, but I don't see any way to enter commands.

    You need to have your Evo connected to the computer via USB. You also need to have the fastboot binary on your computer (install the android sdk tools if you haven't already). Then from your bootloader, select the 'fastboot' option. That will put your Evo in fastboot usb mode. Now, open up a command prompt on your computer, and enter the commands from the terminal. To check if your phone is detected before entering the commands, type 'fastboot devices' then hit enter. If your phone is detected, the command prompt should output your phone's serial number. If so, then you're good to go ahead and enter the commands. Good luck.

    This might be a backwards fix but has anyone tried running a RUU to see if it fixes that.I remember having that problem awhile ago,and I'm kinda sure that's how I fixed it. If anyone wants to give it a go here's the newest one, you will have to reroot but you'll stay s-off...
