Help [Solved]Bootlooping and can not mount sdcard[and other information]

oh, its booted after another attempt and it gives me the "mount disc drive" option.

Two weird files now on sdcard.
qxdm_20101210_182942_1.dm
qxdm_20101210_185622_1.dm

This is all very weird

Hi LFcFan,

I had those files before I sent my phone to repair (may not be exactly the same but similar). I have no idea what that is.

Just have a dump question. I would like to unistaller android USB drive in my laptop. I just delete the android USB driver folder or have to remove android sdk folder too? Thanks.
 
@rx93
No idea how to uninstall the drivers without my phone connected.
I know the drivers on my WinXP are in C:\Windows\system32\drivers folder but not sure which files are for the desire/sdk/adb/htc ect.

For your future reference:
On my WinXP with my phone connected, I click the "start button". Right click "My Computer" and choose "Manage". In the "Computer Management" window choose "Device Manager". Click the little "+" symbol next to "Android USB Devices". It should then show "My Htc", right click it and choose "Properties". Click the "Drivers" tab and click "Uninstall".

do you currently have a problem or are you being meticulous looking for one?
i cant work it out.

is there currently an issue?
im not sure of you being able to use fastboot ls /sdcard. what error does it return?
i thought ls was an adb command
 
OMG, I can't believe you are not tired of me yet :p

If I had a middle name, it wouldn't be meticulous.
I will try to slow down and give you some better information.

I think you are spot on with that fastboot ls /sdcard command. At the time, I didn't know how to check if my fastboot strings were correct but as you will see in #5, I guess they are and it was the command I was trying that were wrong.

The sdcard which is now a goldcard should be all FAT32 and have no partition.
Default connect type is "Disc Drive".
"Ask me" is ticked.
"usb debugging" is ticked.
"stay awake" is ticked.
"unknown sources" is ticked.

Each time I connect or disconnect usb lead I hear the usual sounds.

#1 - During normal running:
Connect usb lead. Safely remove hardware icon appears on taskbar. Normal connect to computer menu options pops up. Sdcard accessible via phone and "My Computer".

#2 - During recovery mode without selecting any mount options:
Connect usb lead. Safely remove hardware icon appears on taskbar. Can not access sdcard via "My Computer" (which I believe is normal).
"adb devices" command lists device number and recovery.
"adb ls /sdcard" lists two things "000041ed 00000000 4d02bde3 ." and "000041ed 00000000 4d02bde3 .." no idea what they are.
"adb push c:\a.png /sdcard" copies a file named a.png from C:drive to this part of the sdcard.

#3 - During recovery mode without choosing any mount options:
Connect usb lead. Safely remove hardware icon appears on taskbar. Select "mount USB storage". Can access sdcard via "My Computer" (which I believe is normal).
"adb devices" command lists device number and recovery.
"adb ls /sdcard" lists two things "000041ed 00000000 4d02bde3 ." and "000041ed 00000000 4d02bde3 .." no idea what they are.
"adb push c:\a.png /sdcard" copies a file named a.png from C:drive to this part of the sdcard.

#4 - During recovery mode without choosing any mount options:
Connect usb lead. Safely remove hardware icon appears on taskbar. Select "mount /sdcard". Can not access sdcard via "My Computer" (Is this normal?).
"adb devices" command lists device number and recovery.
"adb ls /sdcard" lists everything on sdcard which is viewable when via phone and laptop during normal running.
"adb push c:\a.png /sdcard" copies a file named a.png from C:drive to this part of the sdcard.

#5 - During fastboot mode:
Connect usb lead. Safely remove hardware icon does not appear on taskbar. Sdcard not visible via "My Computer"(Is this normal?).
"c:\sdk\tools\fastboot devices" command lists device number and fastboot.
"c:\sdk\tools\fastboot reboot" command reboots phone.

An unusual thing that is occuring when nothing has been connect to the usb for a while is that I sometimes hear the plugged/unplugged from usb sound audio. Not sure if it is the plugged in or unplugged sound.

So, I think everything is ok.

The only things that I need to learn about are:
The cause of the unusual audio from laptop when nothing connected or removed. I understand this is a phone forum so I don't expect to find an answer about my laptops weird behavour here.
The part in #2. I assume there must be an area in the sdcard to store information about itself like "I am a goldcard" for want of a more technical description. But should I be able to push files to that area if it is not actual set as a partition?
Paragon Hard Disc Manager tells me my 8gb sdcard has a single area of 7.4gb in FAT32 and would show a seperate partition of ntfs,fat16,linux swap ect. I have no issue with the missing 600mb because I believe thats due to the way memory devices read/write (or something) and it is quite normal. For example my 100gb laptop hard drive only shows 93.1gb of ntfs.

Sorry for such a long winded post (I hope you didn't fall asleep half way through) but as you (rastaman) and Dan have suggested, I should make sure my phone is functioning correctly before attempting anything else.
Although, I reckon you must think I am crackers for doing some risky things already.
 
as i thought and why i asked the question "is there anything wrong"

everything youve done has proven your device is completely normal
sdcard is not mass storage, when you mount mass storage the sdcard is seen as physical media.
sdcard is a term used in android for external media
when you mount /sdcard its not mass storage, its allowing adbd to see that patition and query it and run tasks on it etc
this is why you have an option on clockwork to mount those partitions as you would mound /systen /misc /recovery etc

so basically everything from the phone phone/sdcard perspective is perfectly fine.

the two files you see, i have no idea and wont pretend i know but someone else on this thread said they see them so its probably normal
as for the card being a gold card, that hidden in the mbr i think, its not an accessible area.

7.4gb is 8gb, in real computer terms everything is binary and not metric. binary 1gb = 1024
so there are less bytes than what there should be in a 8gb card as its calculated in metric so the computer sees it as being 7.4
Gigabyte - Wikipedia, the free encyclopedia

basically sellers and manufacturers are exploiting this phenomenon and calculating a gb as 1000 instead of 1024.
 
Thank you very very much Rastaman and Danfrance (also, rx93 and akashi aswell) for your time, patience, input, guidance, reassurance and information.

I will update the OP soon with a summary of the whole thread/solution/fix.
 
I was going to pm a moderator because I was guessing (from experience on other forums) that I couldn't do that myself.
Going to investigate after updating OP.

cheers Dan
 
Hello Guys!
I have exactly the same problem, I wanted to run RCMix ROM on my phone but it went to a bootloop finally I managed to get it back to work (with an other SDCarda I installed a stock ROM foryo 2.2 and now it is working) but now it dosen't mount my SDCard my card is 8GB class6 my phone is s-off and also it had CM7 Hboot but now it has bravo Hboot cause it was needed for froyo ROM, please help me to find a way to make phone know and mount my SDCard, I can see it on my laptop and format and even partition it (and acctuly I did it 1Gb ext3 and rest fat32) but still my phone doesn't mount it and shows this error "E:Can't mount /dev/blocl/mmcblk0 (or /dev/block/mmcblk0p1) (invalid argument) Error mounting SDCARD:!" I tried manythings but I couldn't but I didn't partition it with gparted. I did with mini tools please help me.

Thanks in advance
 
I think to restore sdcard functionality you need to get into fastboot mode and type
fastboot oem enableqxdm 0
then
fastboot reboot
in the command prompt.
