USB Storage stopped working. - General Questions and Answers

I have asked this on androidforums.com as well, but i'm hoping I might get a quicker answer here.
I have a rooted LG P500 running cm7, the usb storage has always worked fine. But last night I plugged it in, the computer made the right noise, the phone picked up being connected, but when I pressed turn on USB storage, it tried for a minute, then stopped trying and went back to home screen and changed my cm7 theme (also started displaying telecom instead of the usual skinny for my network, not a big deal, skinny is owned by telecom, but still strange) a reboot puts the network back, the theme needs to be changed back manually.
I have tried this several times now with the same result each time.
The only thing I can think of thats changed recently is I partitioned my SD card, but of course I have used USB storage since then to put all the stuff back on my SD card from computer.
I have nandroid backup from before I partitioned, but don't want to use that if I don't have to, and not sure if it would help anyway.
Help?!

Try to clear your cache and dalvid cache too

Thanks, have just tried that, and then tried to connect again and its now stuck o the usb connected screen where it is trying to turn on mass storage (frozen, the circle is not going round anymore). I think I am going to have to pull the battery.

Also everytime I reboot my phone now it changes my theme.
I think maybe the partitioning didn't work properly, when I did it I went up to 136mb internal storage left, and now I am back down to 43mb again! Even though darktremor a2sd says that my apps are on sd. Is this why things aren't working properly? Please someone help!

When I unmount the SD card and plug it into a card reader in the computer it says "USB Device not recognised" and something about it malfunctioning. is this normal for a partitioned card, or is something wrong?
Interestingly when I unmounted the SD card it changed my theme and went back to telecom as my network, so obviously the problem is something to do with the SD card, but all the apps etc on the SD card work fine.

Update: Have USB storage working in recovery so situation is not so urgent now.
Still would like to sort out whatever is going on though if anyone knows, I am obviously having some kind of issue since my theme is always resetting to stock cm7 theme when I try connect USB or reboot the phone.

Phone won't turn on...keeps restarting

I've read in other forums of this problem but have not been able to find a solution (not entirely true).....when I turn the phone on in the morning, it just keeps restarting without going to the home screen. Sometimes it take 2 reboots sometimes more. The only way it will boot up correctly right from the start is to take the mem card out, so I think that's probably the problem, but it's not a corrupt or problem card. Once the phone starts and I put in the mem card all is fine.
I want to try to format the memory card from the phone, but don't know how to. Anyone else know how to do this? Also any other suggestions or solutions?
I got this once. Somehow i got the phone on. I just took the card out and put it in when its about to restart. Mabye it was luck, but i dont know. But if you get your phone on again, I would certainly format it (clear storage)
Does your phone ever act up again after that? Mine still does. It turns on fine without the memory card in. By the way, how do you format the memory card on the phone?
Mine rebooted all the time until I removed Facade. Hard Reset the phone and didn't install it and haven't had the problem since. I know Facade isn't "compatible" yet with WM6, but other than rebooting it worked fine.
Really....I'm going to try that and see what happens.
For those that have this problem, it's true. Once Facade is uninstalled and a soft reset, the problem went away....
I had this happnen to me for the first time today. I had the phone off all night (was testing another device) and then when I put my SIM back in and powered up it went into this reboot cycle. powerd off, even took the battery out still no luck.
Then I took the SIM out and tried to power up and it came right up. Powered off and put the SIM back and it worked agian first time.
Not sure, but maybe the SIM was not fully seated... since this was the first time I actually took it out since I get the VOX...and this was the first time I had the problem...
Regards -John
I had the same problem, although I never installed Facade, Initially the phone was fine and the it started re-booting on startup. I saw a suggestion of running SKtools and removeing duplicates in the Notification table, this worked for a while, then it came back again.
At first the only cure appeared to be to re-boot without the sd card inserted - inserting it again after the phone was running (it even had the same problem with a blank card inserted)
I then read abot someone putting the phone in Flight mode before turning it off - this also solved the problem - better than removing the card each time.

After hard reset - lost option to store attachments on storage card
I had the same problem and solved it by hard resetting the device. However after the hard reset the option to user the storage card for email attachments has disappeared from the pOutlook options screen.
The SD Card is OK and I tried to solve it by a new hard reset, but it is still not resolved.
I would be very graefull for the one that has a solution for this.
I have the same problem with my SD card.
With the card inserted the phone keeps rebooting.
With the card removed it starts normally.
When I insert the card when WM6 is running the card is normal accessible.
Tried an other card and also a 1 Gb card. Same problem over and over.
I'm going to try a Kingston card.
If anyone has a solution, I'll be happy to hear it.
i have my microSD inserted when i power on my Vox but didn't have this problem. what rom version do you have? my rom version is 1.15.405.2.
I have a friend with a similar problem. Would appreciate any further input on this situation. Has anyone taken a look at Paul's (from Modaco) answer to soft reset loop????
Check it out and see if it does anything. Want to know if that'll fix it before I take the phone off his hands.
Hi all,
Like many Vox users, I've also suffered from this problem.
I've noticed two scenarios which helped me solve the "boot-loop". Hopefully they'll help others.
I once had a GPRS monitor application installed to my strorage card. Re-installing to the phones memory helped me.
Also, when I had bluetooth turned on, I powered down, powered-up again, and the phone booted okay!
I think theres a few variables involved in this, and no single "silver bullet". Hopefully HTC will provide an official fix soon.
Michael.
Friends,
Thats all humours. Don't need to remove/install any software. All work fine except you reboot and remove your SD card.
Its simple: if rebooting occurs, just remove SD card and once booted, reinsert SD card, simple! nothing else need to do.
Its true that its a bug with WM unfortunately; i don't know when would it be resolved.
i have tried to boot up with 512MB & 1GB sd card but never had this rebooting problem. Maybe you can let me know your current rom code version and i will try to verify the problem?
I have got the same problem my phone keeps on restarting...
when i put the mem-card after restarting it is being opened as storage card 2, and default storage card option asks for turning on the bluetooth.
Re: Rebooting of Vox
Hi,
Had this problem once (and drove me nuts!, I was out on tour, no PC access nothing).
I formatted the SD Card (Its always better to use a card reader and format it from a PC.
Another I had this problem (hope you are not as dumb as me ):
I use TPC and set it to ultra slow . So every time I booted up, the CPU was not simply powerful enough to cater to the power requirement and rebooted. I had to do a Hard Reset. Hope you have your contacts backup before you go for a hard reset

If you have bluetooth file explorer turned on, it will show as a storage card
i had it long time ago with one of the official htc roms.
The solution is to make loose the simcard-slot in the middle of the booting.
Vox will turn off.
Close and start the phone again.
It should be over then.
Re: Official ROMs
Yeah! The official ROMs suck! actually the best solution will be to switch to a custom ROM from Dr G/FH / fireburned, they are much much better feature wise/ battery backup wise and speed wise. I think HTC should try using one of those ROM as there official ROM

[Q] Captivate Black Screen on Reboot

My problem started when apps from the anroid market began to update on their own. I'm not sure what apps they were, but my phone when out. After my phone went out, I took the battery, SIM, and Sd card out of the device and tried to reboot it. Now, when my phone boots, it gives me the ATT screen, goes to black with the bottom row buttons lit up and the phone vibrates once and twice in quick succession and then goes out again. My phone has been acting this way for the past 4 days. On occasion the phone will completely boot for a minute or two, and then will go out and reboot to the black screen. I'm not sure what I can do next. I do NOT have a rooted device and the majority of my music is located on the internal sd. (I'm just now figuring out that the internal and external SD are not the same) I don't want to lose the media on the internal sd and I don't want to lose my bookmarks. I have tried to transfer files from the internal to the external sd, on the rare occassion of when my phone fully booted for a quick minute, but I had no such luck. I have tried backing things up on my computer, but I get an error message that the USB is corrupted and has malfunctioned. I have read about ODIN3, but I have not tried to flash the device, everything is the way it was when I bought the phone. Is there any hope for me? Will a hard reset wipe the data off of my internal sd? I just want my media files and possibly save my bookmarks....PLEASE HELP!!!!!!! What can I do?........Samsung Captivate 2.1
No you shouldnt loose your media, use this method.
Thanks a lot!!!!!

Can't access the SD card via usb.

At first it actually worked and I got a few apks loaded up, but now it absolutely won't cooperate and I have been wrestling with this all night. Getting various errors, basically the PC just won't recognize either the phone or the SD card. Can anyone help me out here?

don't move apps to the sdcard.
uninstall whatever apps you moved to sdcard, reboot, reinstall them and keep them in internal memory.
I didn't move any apps to my SD card. I installed them from it. They were apk files. Installed in internal memory.

Known issue. Mine will also just stop seeing the SD card randomly. I'll know it when the phone rings and the ringer is some default garbage instead of the ringer I had assigned from the SD card.
I've yet to see any actual working solution. Simply rebooting the phone will usually fix it for awhile. Will probably have to wait for a Moto update.
what class is the sdcard?
people have been having issues with class 10 cards (although i have not).
try backing up everything on the sdcard, go to settings > storage and format the sdcard using the phone. move your stuff back onto the card and see if the problem continues.

Been there done that. Mine is a class 4 Sandisk 16GB.
Make sure you don't have any apps on your SD card. When you plug in your USB cord in it unmounts the SD card. If you have any apps on the card that are running is when you run into the problems being described as the phone is trying to unmount the card but can't due to the apps running.
Card is the stock 2gb, don't know what class.
No apps running from the card. Tried rebooting the phone a few times, turning USB debugging on and off, using different connection modes... No dice.
Def keep USB debugging on. When you plug your phone in does the USB icon show up in the notification bar?
Yeah, it does. And it charges.
OK grab the USB icon and pull it down just like a notification. You should see either 3 or 4 options, charge only, windows media share, etc. Sounds like you have charge only picked. Choose the media or data one and hopefully that will get you squared away

If u pull the card you should see a number on it in a tiny circle, the number in that circle indicates what class the card is. I had this problem once, after I rooted. Did factory reset and its been all good since....this was 2 weeks ago.
Sent from my MB865 using XDA App
I've tried all the USB connection options multiple times.
I had to uninstall moto drivers and then reinstall them on my pc. All was good after that.
Also done that multiple times.
For now I'm just using my ghetto rigged card reader - digital camera and micro sd-sd adapter. Hahahha.
Probably just going to have to wait for an update and some more moto support for this phone on the pc side. Speaking of updates, this phone's been out for a month. Getting to be about time we at least saw a few bug fixes.
I'm sure you did a battery pull. I just went through this with my device, and that fixed the issue...
Actually, I didn't.
It seems that if there are any apps installed on the sdcard, it can't be accessed via usb.
Mine actually just started doing this as well. It was working fine, and now I cannot get it to mount as a mass storage drive on several different computers. I had three apps installed on the card, all games. I uninstalled all of them and still no mass storage.
So I've been making sure no apps get installed on my sd, or even any app databases because sometimes an app will install internally, but put its database on the sd. So none of that! I enjoyed a few days of being able to use usb mass storage, then a couple days ago it became inaccessible again. I checked for apps that may have slipped something onto the sd but didn't find anything noteworthy.
I left the issue alone, praying for a fix materialize from the etherworld, when something interesting happened today. I unmounted the sd and installed a new app, and a notification came up saying the app could be moved to the sd; but the notification used a wierd sound to alert me, presumably because it couldn't find the default audio file on the unmounted sd. So I then wen't to settings/sounds...oops... android crashed and rebooted with the sd card mounted; and I have access to usb mass storage again. Prayer answered?

Can't mount SD-card

It was working uhh I dunno a few days ago, this morning it wouldn't mount. I initially thought it was a MIUI problem (1.11.1) I rebooted, nothing. I wasn't even getting the usb disk toggle in my status pull down. I checked the USB settings and "ask on connect" was on. So I rebooted into RA and tried USB-MS, still not coming up on my PC. On my phone I can go into Astro and see the SD and everything on it fine, I played some music and watched some videos, so I'm assuming there's nothing wrong with it. I'm also assuming there's nothing wrong with the usb cable because it's charging my phone.
I've exhausted ideas on how to fix this, any help would be lovely.

Try plugging your SD card into PC with an adapter. You may need to reformat your SD card. SD card corruption is a known issue with MIUI

But if the card was corrupt then wouldn't the phone be able to not access it directly either? I know when I ran my last Rom (Synergy) a few times when I plugged the cable in I'd get windows popup saying errors detected and it needed to be scanned. I don't have an adapter I guess I should to go and get one.
thanks for the reply.

Here is what I would do. Use dropbox to back up any files that the phone doesn't see as corrupted then reformat the SD card. Also remember that when you unplug from the PC that you have to "safely eject" it before unplugging. This is normally the cause.

Thanks for the feedback, it magically decided to pop up on it's own, I had it plugged in and charging and when I came back from lunch there it was. I scanned it and it seems a-okay. I'll remember the safely eject thing, I know about it I just tend to forget to do it, and by tend I mean always lol

(solved) Big external micro sd card issues

I am getting an error, old as android itself, with my new s7 Exynos. "The device has either stopped responding or has been disconnected". This happens when I try to copy my 25 gb music library on external sd card. I tried all usual stuff like:
- Use different cables
- Reinstall samsung drivers via Kies
- Transfer using MTP or PTP
- Use USB Debugging on and Stay awake option on
- Tried pushing folder via ADB push command, but it says "Read-only file system" when I typed location as /sdcard1 (which I think is an extSdcard right? It did copy a .txt file if I typed just /sdcard but that is internal storage)
- Tried with Samsungs own SmartSwitch but the bloody thing doesn't even have an option to copy files to device (only backup and restore), and Kies is not supported for S7.
On side note, the same sd card worked perfectly with my S3 and gave no errors. When I inserted sd card into S7, I formatted it inside the device. What other troubleshooting stuff should I do? I can't believe that this crap is still an issue. Why can't we have our USB Mass Storage back?
-----------------------------
Big edit:
Ok my phone doesn't seem to like this sdcard. I inserted microsd card to my s3 and copied 17 gb of files, to check if there is a problem with MTP connection or sdcard, but it copied all 17 gb of files without any errors or problems. I checked on phone if it reads correctly, and all music plays fine instantly without any lag or freez. But when I inserted this micro sdcard back into my s7, there was a massive lag/freezes. When I click "MyFiles" or "SolidExplorer", or any other file manager, there is a big lag/freeze, and file manager never opens (it is always stuck). Also, when I go into settings and when I press "unmount" under storage, nothing happens. When I press home, it doesnt go to home screen, and says that touchwizz is not responding (if I change default applications to Nova launcher, it does go to the homescreen though). When I try to open Shealth app, it doesnt open it. Also when I put my phone to sleep, I have to wait like 10 seconds for screen to turn off sometimes. When I pop out sdcard though, all the problems go away INSTANTLY. Everything is smooth again and responsive, file manager opens, shealth opens, everything works like it should. If I insert sd card back in, same problems happen.
And as a cherry on the cake, I put sdcard back into my s3, and everything still works fine. All files are readable, music playes, etc.
When I was searching online, this is the closest thing I have found that explains my problems, but there was no solution: http://forums.androidcentral.com/samsung-galaxy-note-4/542854-sd-card-freezes-note-4-a.html
Anyone ever experienced anything similar?
EDIT: Luckly, it was not my phone fault. It was my sd card. Even though it worked fine on s3 and my friends s5, it didn't work in s7 for some reason. I purchased samsung evo+ and it works flawlessly.
try format as exfat ?
Can't, it is 32gb card and it is not allowing me. Also, sometimes when I insert it, the whole phone freezes complitely. Once I even had to use volume down + power button for 10 seconds reset method since it froze complitely. Card is in fat32.
edit: I also tried copying files from USB flash drive (adata 64gb exFat) to sdcard directly on my phone, via OTG cable. It also stopped the process midway and phone wouldn't enter into any file storage (it froze). I had to remove sdcard again and insert it back in to remove that freezing.
edit2: I copied 17gb folder full of subfolders to internal storage, and it transferred without any problems and pretty fast (about 20 minutes). That means MTP connection and drivers are fine. When I tried copying the same 17gb folder to external sd card, "device stopped responding or has been disconnected" error again.
It seems like this is a lot bigger problem, as this is not really an issue about "device stopped responding" anymore. I edited first post. Still looking for solution.
Search the forums, this is a known issue with some phones. You can try other cards, sometimes that will help. Or get your phone replaced as it's a hardware defect. My first S7 was like that. This one reads sdcard without issues (but has radio issues).
