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

Calkulin · Jun 5, 2010

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.

swaze · Jun 5, 2010

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?

sruon · Jun 5, 2010

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

Hopefully this fixes the USB issue, so I'll report back shortly

Wiping/Hard reset didn't fix it

If it works... make sure this get stickied and ****s

West650 · Jun 5, 2010

I'll think I'll wait on rooting my Evo when I get it. I don't want to get into any problems haha.

Actually it did fix it, I have the SD card & USB function back, so I'll update the first post with the instructions

So thanks a lot for that sruon, I owe you one now

sruon · Jun 5, 2010

No problem!

Calkulin · Jun 5, 2010

Ok updated the original post with the instructions cause I know I'm not going to be the only one with this problem

Darth Pooh · Jun 5, 2010

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.

Glad I could help but be sure to thank sruon as he is the one that posted the link

I don't know what exactly caused it, I don't remember exactly what I did right before the restore failed but I know I was working on de-odexing the system and since 5pm was coming around, I decide to restore and it failed. So I really don't know if it was the failing of the restore or something else(had flashed the Froyo ROM about a hour before too).

I'm already working on something don't worry

But I need to finish my v1.6 ROM for the Moment first

p-slim · Jun 6, 2010

sorry calkulin, me and you go way back, i can't wait for you to start building roms for this bad boy. unfortunately the same thing happened to me, i think my friend broke it when i asked him to pull my sd card out, anyways after i took it out it never read another sd card again. i had to get my evo exchanged yesterday, so the 1st day i didn't even get to play with it.

Calkulin · Jun 6, 2010

Nice to see you p-slim, buy yeah I can see how someone can damage the SD card slot, it definitely is a pain to remove and insert a card, especially if you have short finger nails. But don't worry, mine only lasted 3 hours before I "thought" I had killed it, so your not alone
