[Q] USB Mass Storage mode turns off immediately - Nexus One Q&A, Help & Troubleshooting

Something weird happened today with my nexus one. I tried to start up an app (Bejeweled Blitz) which froze my phone completely, so 5 minutes later I removed the battery from the phone and started it back up. Now, certain things were missing off the phone, like airplane mode.. the home & search buttons wouldn't work.. my wallpaper had changed on its own to a default one.. and my homescreen had none of the app shortcuts on it. But my apps were all in the drawer, as far as I could tell.
but anyways, I plugged the phone into my computer via USB and clicked Turn on USB storage, but it would turn on for a second or less and then go back to the Turn on USB storage screen.
So I tried restoring factory settings, reformatting the memory card, making sure debugging mode is off, and all that. I also had windows check the memory card for errors by plugging it into a microSD card reader (There were no errors). But nothing I do fixes this problem. Any ideas? Is my microSD card broken now? Is Bejeweled Blitz evil?
Before all this happened, I was running CM 7.2 passion, and I had used mounts2sd to change the internal storage to about 990mb. Everything was fine for weeks, but this randomly happened.
Thanks to any who try to help.
EDIT: I don't know why I hadn't thought of it before, but I put a different microSD card in the phone and tried using USB mass storage. The same problem occurs, so the problem must be with the phone itself and not the microSD card. I have no idea what to do, because the phone is already at its factory default settings. Maybe the phone will just never be able to use USB storage mode again?

OKay, I have no idea what happened but everything is working perfectly fine now.

Help I goofed

Ok I forgot to unmount my SD card before I switched Sd cards to transfer some date. Bone head move!!!! Anyway now when the phone starts up I get can see my wall paper in the sleep screen. I can see the status bar and see that several apps are started, but open home will not start. I get a force close screen over and over. The Hot button to get to the settings will not work and so I can unmount and remount or turn off open home. Satus bar is there as I said, I can pull it down between force close screens, but the rest of the screen is black. Any Idea besides wiping and reinstalling everything?
got it, I could get into process manager via the status bar. I uninstalled open home, unmounted/remounted and reinstalled.
How did you swap SD cards without unmounting? you can't mount the card while the phone is off, and you can't swap cards while the phone is on.
I just reinstall the apps that are foreclosing.
Well I thought you had to go into settings and do something before you took the SD Card out. Guess not. Anyway I turned off the phone, took the SD card and put in another that was in the my G1. I guess this created the problem as their were files on the G1 card. Most apps that were installed on the SD had problems. To completely fix the problem I had to format and re-partition my SD Card. I went ahead and wiped and reinstalled Cynogen as well. Everything is fine now just have to get back the 90 or so apps I had on the phone.

SD Card Error

I am using Cyanogen 5.0.6 on my N1. I flashed it about 5 days ago.
Backstory: So I was connected to my car stereo via bluetooth on my way to work this morning when the songs stops playing. I then pressed the skip button on my receiver but nothing happened. I then looked at my phone and realized that it was off. I tried pressing the power button to turn it back on but that did not work. Then I removed the battery and then replaced it and pressed the power button. It turned on. The main problem became evident when I got to the home screen and it said "Blank SD card - SD card blank of has unsupported filesystem."
Is there a way to recover the data that was on this sd card? It is asking me to format the card, but I would rather recover the files if possible before formating. Also, is this a glitch with Cyanogen, the 5.0.6 ROM, Android 2.1 or something else?
If anyone could help me, I would greatly appreciate it.
No idea what could have caused it but as for recovering files just try one of the many programs out there.
Ive persoanlly had success wity a program called recova for windows
Thanks Phantom.
I had a spare memory card at home. It was full of videos so I had to format the card. Once it was formatted, I stuck it in the phone and rebooted. Everything was fine for about a half hour. I then loaded up some of my files that I wanted on the card, mainly just photos and documents. Then I thought I would go back to Cyanogen 5.0.5.3 so I loaded up the zip file on the root of the card and turned the phone off. When I went into bootloader it wouldn't recognize the card. So I was forced to restart the phone. Once it got to the home screen, a notification popped up saying that the SD card is damaged. [naturally there were expletives]. So now I have two SD cards that I cannot use on my phone. When I put the cards into a USB adapter, the computer only sees a few MB of the SD card and does not allow me to format.
I have now just about reached the limit of my computer knowledge.
The two main questions are:
1. What caused this?
2. How can I fix it?
Please keep in mind that I am a noob when it comes to most of this stuff so I would appreciate the help to be kept in layman's terms as much as possible.
Thank you!

[Q] Internal SD card disappearing when KIES is used?

Anyone else having an issue with the internal SD card on their SGS dropping off and not showing up after using KIES, in fact it might be every time I plug the phone into my computer and select a connection option.
I've been using the JH2 Eclair version for my Bell I9000M since it came out. a couple weeks ago I had an issue with the OCLF crapping out when I dropped my phone while it was running an app and it popped the battery. It messed a bunch of stuff up, I lost some apps, had a number of them that refused to re-install and a fair number of FC's on random Apps that were stable prior. I also experienced a number of FC's on the gmail app in relation to syncing.
I then did a Factory Reset and then finally a full re-install of JH2 and all those issues went away. Now the only problem is the fact that the SD disappears from inside the OS, after plugging it into the PC, If I connect it Via KIES it will work once, then the phone begins to flash the Kies app in and out on the screen on my second attempt and the SD card vanishes.
I have found that if I do a 3 button boot and go to the update screen and run the option that deletes the Cache partition and reboot the phone it fixes both the KIES issue and the missing SD issue until I plug the phone into my computer again.
I'd be interested in hearing any ideas people might have as to why this is happening and what if any options I might have to permanently fix the issue.
O.
I have the same problem. I'm using JH2 as well and after unplugging from my PC my internal SD and external SD are unmounted. A reboot remounts them. I rarely use kies so it's just kind of an annoyance

Can't Mount SD Card via USB

First off: Motorola Droid running CM 6.1
So I've searched around, and everything I've found seems to be missing an aspect of what's happening with me, so I figured I'd just go ahead and start a thread and ask.
Basically, my SD card has been working on and off. It started one day when I turned off my phone and then turned it on later. The SD card was in and I could access it via Root Explorer, where I could see everything, but none of the apps were working at all. Restarting phone did nothing. I turned it off, pulled out the battery and pulled the SD card out, blew it out a little, put it back in, turned it back on, and it seemed to work as normal. I wondered if my problem was gone, so I restarted again, and same problem, no apps. I finally got it back on with the apps on the SD card working, but now, I can't mount it on my computer via USB. When I plug it in, it says drivers were installed and device is ready to use, and it starts charging, but there is no notification on the phone to mount the SD card. On top of that, I can't seem to install anything or update anything through the market, and I'm not entirely sure all of my apps that are on my SD card are there, but I can't be positive, because all of the ones I most use are. I'm sure that if I restart my phone, the same thing will happen again, so at the moment, I'm fine that my apps are working, but there are times when I need to mount my SD card to transfer files and such. Like I mentioned, I did search, and the closest thing I found was USB Brick which seems to be solely focused on the HTC Desire, but still seems to miss some aspects of this, mainly, no one mentioning that they could access their SD card while the apps weren't working. This makes me think it may be some sort of problem with the system or perhaps something wrong with android_secure or Android on my SD card. (Maybe an app on there messing something up?)
Any help would be appreciated. If this is a dupe thread, I'm sorry. If you could point me where I need to go, I'll go there and this thread can be deleted or closed.

Odd Lockups with multiple Roms

Alright guys this forum is pretty kickass and I was just wondering if anyone else could give me some insight to these weird quirks my Moto Droid4 is giving me.
Issues:
-Many apps that need to access SD card don't save properly i.e. TB gives insufficient storage error on scheduled backups, sometimes photos don't save correctly
-^^ Also related is sometimes when trying to connect as "Mass Storage Mode" via USB to my computer the device will lock up or when I try to write files to the SD card the transfer will lock up and the phone becomes almost unresonsive
-SD card and writing to the card becomes fickle if I ever mount and unmount, to the point where sometimes it won't mount until I reboot the phone
-Sometimes the phone will just become unresponsive altogether and exhibits periods where it will turn on the softkeys but the screen won't turn on. Hitting the hold button then ends up just toggling the softkeys.
I've tried:
-3 Different Roms now, all JB. Two different 4.2.1 and one 4.1
-Checking the SD Card with windows built-in disk checker and sector fixer. Everything "Passed"
-Turning off all CPU overclocking components and apps.
-Making sure newest Busybox and SU app is up to date and allowing all apps.
I think its the SD card but I don't see how the phone not turning its screen on or becoming sluggish could pertain to that.
Thoughts?
Thanks in advance guys :fingers-crossed:
Have you tried to back up all data of the SD card format the card put data back on and try again... my wife's RAZR did this and that fixed it...

I believe I have, but I will do it again as soon as I'm done with the Disk Checking for the 3rd time. Will post results
Completely nuked my internal storage and SD card, by formatting. It still does lockup everyone now and then and by that I mean it will blink a notification, and sometimes turn on the softkeys when I go to hit the hold button but the screen never comes on. sometimes the softkeys respond to me hitting hold and they go on and off but the screen won't it requires a reboot to fix. Is it the phone at this point?
Changed to a different SD card same model same brand and class and since then I have not experienced any of these problems. And I can rule out bad files on the card because I copied over everything from the other card straight to this one. Its been about 5 days with not one problem. I will give it 10 before I call it.
