[ How-To ] Fix SD card not being detected & USB port not working

---

Decided to update the instructions for this fix.

Thx to sruon for the fix

Original instructions pulled from IEFtm's post @ Modaco


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

factory reset?

That was the first thing I tried

Can you pull the battery and try a different sd card? Maybe reformatting (full) the card may help. You could always restore using the base sprint rom and try rooting again

This is probably the same thing known as "USB Bricks" for HTC Desires... It has been untested on EVO 4G but here is a topic that explains it for HTC Desire.

It should be the same mechanics so... I have good hope for you.

did you try pulling the battery and trying the same process? I dont think you bricked it, seems like something else is going on. Did you remove the SD card while it was running?

Btw to reenable SD Card and ****s go into fastboot and type

fastboot oem enableqxdm 0
fastboot reboot

You tried hard resetting already?

Turn the power off.

If your HTC EVO 4G is frozen, pull the battery out and reinsert it

Hold the Volume Down button

Press and release the Power button

You are now presented with a menu that allows for Fastbook, Recovery, Clear Storage, and Simlock

Select Clear Storage by pressing the Volume Down button

Press and release the Power button

Now simply confirm your decision: Volume Up for YES and Volume Down for NO

If you selected YES, all data including third-party applications will be deleted from the HTC EVO 4G. Once the wipe is complete, the phone will reboot to its factory fresh state.

This did let Android recognize the SD card, so thanks
