Root stops working - Optimus One, P500, V Q&A, Help & Troubleshooting

Hey there. I'm having a weird problem that keeps on happening.
I'm on GingerSnap v2.3 rom and this has happened twice by now. When I connect my device to my PC via USB to move data to my SD card the root seems to "stop working".
Suddenly all apps that require root access stop working. I open the apps I get the little toast message saying that the superuses access has been granted but the apps don't get it. For example, on root Explorer I get the toast but then the app says it has to Restart because it doesn't have root access.
The Log on the superuser app says that they are getting it but still they do not work. Plus BusyBox seems to not work either, if I remove the root access to any app to try to Regrant the permissions the app gets stuck on "requesting root access" until they eventually crash
The first time it happened the only solution I could think of that worked was Reflashing and losing all my apps since Titanium BU is not working I can't back anything up
Please help! I don't want to Flash the rom again! :banghead::banghead::banghead:
EDIT:
Right after posting this, i remember disabling the USB debugging option on the settings. So i enabled the setting. Connected the USB as a mass storage unit (so it would deactivate the SD card) and then turned it off so It would load my SD card again (just in case that plus the lack of debugging was causing the glitch) and it started working
I don't know if this is an issue with this rom only but apparently you cant disable the USB debugging. Also I don't know if the thing with the SD card and mounting it as a mass storage unit was also part of the problem but I thought it was worth mentioning just in case.
I feel pretty dumb by opening a thread and then minutes later finding the solution myself. But I hope it at least can help someone else if they find the same issue.

On disabling USB debugging and restarting the phone the SuperUser app stopped working for me. But these steps above are working out for me too!
Does anyone know whether I need to keep USB debugging enabled forever? Is there anything else I can do? Like maybe install SuperSU maybe?

I decided to just turn off the USB debugging notification. Not sure if it can be done on every Android but I'm on CM7.2 and it can be disabled

I lost my USB connectivity when I manually installed 2.3.4. Is that what you did that caused this problem?

Yeh I installed one of the 2.3.4 Roms (du5t3r's) and before that wiped all data going into Storage menu. I managed to get it back by going into recovery, mounting , unmounting and then rebooting BUT it did it again when I rebooted (testing it). Just shut down, removed battery and its back. Weird. A few apps are giving me errors by saying there isnt any storage. Did you manage a fix for it?
Anyone else experiencing this?

[Q] USB Mass storage mode not working after root

After the root procedure I don't seem to have any ability to use USB Mass storage.
Windows reports it as an empty drive, linux will show the device as connecting and assigns it a /dev/sdx device, but when you attempt to mount or fdisk, it reports no medium.
Any one else having similar issues?
I could always try a reset to factory defaults after unrooting, but I really don't see what rooting could have done.
I used the manual method and had to run zerg several times, however beyond that no other files where modified.
I've already reverted /data/local.prop to stock, no help.
Any one have any other insights?
I had to uninstall motohelper to get USB mass storage working.

When you take a picture, does it save to your sdcard? Sounds completely unrelated huh? Well, this phone seems to have an issue with the sdcard randomly becoming read only. I have had that issue multiple times now and usually it's solved by restarting the phone. Well, I seen your issue today and didn't remember if I had tried to use it as mass storage since rooting it so I tried....no luck. Took a pic, it looked like it saved, didn't get any error, but could not find the pic in my gallery. Then I tried to take a screenshot and got the read only error. So I just took my sdcard out and made a copy of it to my pc, put it back in and rebooted my phone, it's all good now, imagine that. Needless to say, i'm backing up all my apps right now before doing anything else. Then gonna backup my contacts too.
motohelper... Sounds like a stock app...
did you just rm the apk?

I had to reinstall all the drivers through motohelper to get it to work as well =/
No problems now though~
I was able to get my sdcard recognized again but still could not use it as mass storage device, never had a problem with this before root. Did factory reset and all is well.
There is no possible way root caused the issue at all. It stopped working for me once I installed moto drivers, but shows the device with mass storage under it in usb portal mode.

Well then it's one hell of a coincidence! Before root, w/motodrivers, worked fine, after root w/motodrivers, didn't work, after unrooting, w/motordrivers, works again.
Same thing happened with my phone. Actually now returned because of all the issues I kept having hardware wise and wound up going and getting the HTC Vivid. So if any of yall switch I will see you when a Forum is made for this device.

I have until the 24th of this month to decide if I want to keep this phone or not. I unrooted yesterday, will see how it goes this week. I'm not trying to pay big money for a phone right now so we'll see how it plays out.
OK I give up. The problem is intermittent. I'm going to do a log cat next time cause I'm getting about irritated. SOme times it works fine some times not. I've not unrooted or changed anything since the initial problem.
The only thing I can possibly thing is that some of the commands installed by busybox is screwing up the works.
Short of that nothing REALLY changes that could affect the operation of the phone.
What doesn't bare that idea out however is the fact that it EVER works.
**STUMPED**
It does the exact same thing on a completely unmodified phone. Therefore, it's nothing you did to it that's cause the problem.
I have the same thing on mine but it was something with the format of the card.
I flipped it to windows media sync mode then backed up the card and after the backup I unmounted the card and let the atrix format it.
I had the card in a atrix 1 before I put it in the atrix 2 so I do not know if this is the case or not.
This has now been working with out a problem for 4 days now
Same thing happened to my phone, I never rooted it.
Confirmed user error.

Thank you seraphielx! Shortly before finding this thead, I'd noticed that I had a rather large number of files in the LOST.DIR on my SDcard. Which coincided with the seemingly random disappearance of some of the apps I'd moved there. And when I pulled the SDcard to back it up on my PC, there were nearly 600mb worth of files in the LOST.DIR. Most of which were photos, plus (I think) some apps. Thank God I make regular backups!
I believe the problem, at least in my case, has to do with the fact that I could pull the SDcard without first pulling the battery; which I did when I swapped the stock 2gb card for my 32gb card right after I bought the phone. Thus corrupting many files, and probably the file system on the card as well.
After backing up what remained of my storage files, I tried to format the SDcard in the Atrix2, but It wouldn't let me select the option to format, and neither could I unmount the SDcard. So I powered down the phone, pulled the card and formatted it from my PC. Poped it back in the phone, powered up, and was then able to format it with the Atrix2. Since then I've had no issues with accessing usb mass storage, nor with disappearing apps and photos.
Thanx again for the assistance!
For me sometimes it takes a few minutes before I can access sdcard from PC.
Usually it works instantly after phone reboot while not plugged in pc, then it takes ages...

Update: OK, I can't unmount my SDcard, again. Which, of course, means I can't access usb mass storage anymore. The only I've changes made since my last post were to install some apps and change some status bar icons via Rom Toolbox, and I can't believe that has anything with the issue.
If I do a factory reset, will I need to root again?
If you have any apps installed on your SD card you will continue to have problems.

everytime i plug into windows 7 it says hardware ID missing

Please help i cant get my phone to connect to transfer files it says device ID missing please contact hardware manufacturer. I installed the samsung dirvers from samsung but no keis or anything.
I have the same issue on my WinXP machine.
I still get it, but when you plug in the device check the screen and toggle your connection settings on the USB popup.
do you have a SD card or are you just using the internal?
i have internal and external sd.
Yea, make sure you check the phone to make sure it is set as a storage device.

please help!!! unfortunately, the process.android.media has stopped

unfortunately, the process.android.media has stopped.
im also rooted fine using a1 rooter zip in CWM
i get that error on bootup once i hit the homescreen, with ICS custom rom 4.04 on the lenova tablet ideapad A1-07
i cannot get USB connection to computer, it only displays the debugging mode?
maybe i have to MOUNT sd card or something during CWM?
also it won't detect my microSD card, only AFTER i take it back out and put it back in it will detect it
but not on initial startup/bootup
thanks if anyone can help me figure this out!
bump! anyone
how to fix "android.process.media has stopped"
After upgrading to ICS, this error message pops up 1-3 times over the first few minutes after each boot, and periodically afterwards.
After some research I found there is 1, possibly 2 apps/services responsible for this error. I disabled both of them and the error has not returned. I've noticed no impact to disabling these services, though they are easy to re-enable if side effects appear.
The services are "Media Storage" and "DRM Protected Content Storage".
In ICS, you can disable them (or any other app/service) by:
1. Go to System-Apps-All
2. Scroll to the app in the list, click "Disable"
If you have Titanium Backup and are rooted, you can use Titanium Backup to freeze them.
Then cold restart the tablet. The errors no longer appear. Again, if you try this and it breaks something, you can easily re-enable these services.
managed to fix that android.process,media. error but i still CANNOT get my computer and idealpad to connect via USB:crying:
Clear their data
Dont disable them...Try to clear the data of media storage and reboot ..
Try formatting your sd card using another phone.
I too had the same problem.. i used my sd from other phone it worked but not the one in my phone.so i tried formatting my sd card using other phone.
It worked for me.
Thanks very much!! Solved my problem!!
[I used Link2SD to freeze the two applications and WHAM! I'm back in bizzness! Thanks Thanks Thanks!
Plz help me fix unfortunately android media process has stop. It keeps pooping up repeatedly. I already reset my device but still. Doesn't work. Can't even disable media storage and DRM content storage on apps manager... And now I cannot open all my apps . also popping unfortunately (apps name) has stopped.. Plz help me..

[Q] [Not Working] USB Mass Storage and ADB

Hello friends, I am facing a problem with USB Mass storage. Please find the case as below.
Previously when I used to connect my phone with my laptop, it used to show a pop-up notification on either I wish to enable USB mass storage mode or just wish to have my phone on charging only. USB debugging was also working like a charm during those days.
Now, from last two days (suddenly) none of the computers (i have tried on almost 10 different laptops) is recognizing my phone. Though this is the problem, it gets charged over USB without any problems.
Could someone of you please help with your expert knowledge??? I have tried downloading certain applications from Play Store also but no luck at all.
In furtherance to this, please note that I clicked on "format/emmc" while installing one of the custom ROMs through CWM recovery before two days and i suspect that this could have caused a problem.
Please help.

Buddy,
Formatting EMMC is just like formatting SD card and EMMC is Internal SD card.
Do one thing backup all your data and then reboot in recovery and there you will find the options:-
Mount & Storage --> Mount USB Storage.
First connect your phone to USB and to the laptop then do the above said if its connected then its working and you only have to clear the defaults of the USB application.
If its not working then try other rom with proper guidance of flashing given by the OP.
Hit Thanks Instead of Saying It.....
