Phone Cannot Read Any SD card

[slikrishi]

Hello

I have been running CM7.1 for the past few days without any problem except missing Wimax keys. This morning I decided to restore an old froyo sense nandroid backup to see whether 4G would work in that. I restored this clockwordmod backup using the RA_Supersonic recovery.
After the recovery completed the restore, my phone entered a boot loop only making it as far as the "4G" splash screen.

I wanted to try the restore again in the recovery, but it then could not mount my SD card. USB-MS from recovery was also not working so I could not connect to the card from my computer.

I did a "clear storage" from Hboot. Now, my phone actually makes it into the OS and I can do things in the OS, but only for about 1-2 mins before the next boot loop. Thus, during each boot loop, I have about 2 mins in the OS to try whatever I can.

When in the OS, file explorers like Astro cannot read my SD card anymore (the error says something like "cannot create cache"). The SD storage option in the settings menu also says the SD card is unavailable.

When I connect the phone to my computer, nothing happens, no option appears to set as mass storage.

ROM Manager cannot load the newest clockworkmod recovery because it needs an SD card to run.

I have tried another 2GB SD card, same thing happens.
I have tried to format the 8GB SD card using 1-pass zeros, still doesn't work in the phone.
Both of these cards work on my computer with a card reader.

Do any of you have any suggestions for me?
I'm not sure what else to try.

Thank you.

Thank you very much, this worked for me!

I had to download all the adb and fastboot files to be able to fix my SD card.

My USB was also not working from the OS, and even though my SD was fixed, I was still in a boot loop so I could not use terminal emulator to fix my USB - until I flashed a Mik rom which was more stable. CM 7.1 was not stable for me, it was also boot looping. I then accessed the terminal emulator from the Mik rom and fixed my USB.

teh roxxorz, if you feel like it and have got some time to kill, could you explain what the original problems were with my SD card and USB, and how I fixed them? For educational purposes...

4G not working even after restore to old backup

Now back to my original issue that started all this messing around... 4G not working.

I've now used clockwork to restore to some old clockwork backups I have, stock froyo from January, stock gingerbread from July.
In clockwork, I first restore the backup, then I go to advanced restore, and choose to restore the wimax.

4G is still not working: Scanning > Connecting to Sprint > Scanning > Connecting to Sprint > Disconnected.
In "about phone", the 4G mac address is not shown.
Wimax Key Checker says my EVO RSA key is present.

Any suggestions for this one?
Thanks in advance.
