Cannot mount USB mass storage - G2 and Desire Z Q&A, Help & Troubleshooting

Hi Everyone,
I'm currently having this issue where I can't mount USB mass storage at any PC. The green android screen that appears whenever the phone is plugged in immediately disappears when selected?
My current config is in my sig, if that helps diagnose the problem.
Any ideas?
Thanks!

I had the same issue once with a Motorola Droid. I would recommend you to make a nand-backup and wipe the device and see if it corrects.
If not, try with another ROM. This way you can restore everything if you happen to find the reason and know you can correct it from your current setup.
Now, it seems obvious but just to be sure, have you checked in Config->Connect to PC that the phone asks you for the Connection Type?
Regards

Just acted on a hunch and I was right: the kernel that I was using somehow broke this feature, flashing pershoot's fixed it

i have this problem i am running cm7.1 still can not do anything even flashing pershoot and fixing permission. anyone help me?

USB Mounting issue - Really different...

So I have a new one for everyone. Ever since I last reloaded the firmware on my Evo, its been automatically mounting as a usb drive when I plug it into my computer. I think I told it to do that by default, but I successfully changed it, but even though it says charge only, but still mounts to the computer. Its rooted, but stock on the latest OTA with full NAND unlock. If anyone happens to know a way to fix this, I sure would be grateful, its annoying. Its easy enough to fix, just toggle between charge only and mount usb, hit ok, and then the sd card is loaded to the phone, but its kind of annoying to do every time I plug it in to my computer. (I usually charge off my computer, to keep it close by.) Thanks in advance!
Do you have DoubleTwist installed? By default (the moment you install it) it causes this issue unless you go into the app and turn it off under options.

Can't connect to PC after downloading jager rom

I recently rooted my Dinc. I had no problems, had full functionality. Then i wanted to download a quick rom just to make sure it worked; jager rom. After downloading the rom i unplugged safely removed my phone from my pc. I plugged it back in but now i can't access my sdcard. Dont get any notifications on my phone asking whether i want to charge or switch to hard disk etc. etc. I then went to "connect to pc" through my phone settings to set default connection to hard disk, but still nothing. I then went through cmd promp on computer and adb reboot recovery. From there i wiped my memory, cache, and then the dalvik cache. Still nothing and still running the jager rom. Ne one have ne suggestions, been through this, know how to fix it help would be nice. I have full functionality of my phone. Just can't connect to pc.
Most likely your sd card died. It happens. Try it in an adapter in a PC flash card reader. Oh, btw prob wrong forum.
It would still ask what you want to do with a dead sd. The rom should also tell you no sdcard found or bad card.
Reboot to recovery and try to mount usb that way. If that doesn't work, reboot your pc, it happens sometimes to me and just needs a reboot to fix it.
Furthermore, if you're able to use adb, then you are indeed connected to the pc. Don't do the safely remove hardware next time. Just switch the connection type in your phone to charge only and unplug.
Also.. yes, wrong forum.

Disk Drive Access

I recently upgraded to a GB ROM. Now I can't figure out how to access the disk drive option. Need help. And yes I'm a noob.
If you connect to a pc, it should show up in your notification tool bar.
I am connected and the notification bar gives me the following option. Select to diable USB debugging....however I can't seem to get from here to disk drive option.
Try rebooting your phone, and if not, reflash the rom, and you should be all set.
There's an app in the market called "auto mount SD" or something similar. When you open the app you can choose to automatically mount as disk drive when connected to your computer. This was the only way I could get mine to mount at one time.
Widgetsoid 2.x also has a toggle for "mount usb". Occasionally I still don't get the option & hitting the toggle does the trick for me.
Thanks for the help. I ended up reflashing and that fixed the problem, however now I'm having problems with the phone hesitating to wake up.
If you've recently re-flashed, it make take a few times, as it still settling in. If you flashed a kernel to it, the kernel could be the cause.

Ah, the app you're talking about it dual mount sd. It also comes in handy cuz if you're listening to music, or have a lot of apps on your sdcard, they won't get disabled if you use it.
I did flash a kernel as well. Will that settle in or do I need to find a new kernel?

Well a kernel takes about 2~3 days to settle in, so you can make your final call then, but its its an sbc kernel, one of the side effects is that it can make your phoen laggy, cuz as the slight delay upon waking. Changing the kernel can fix that.
Thanks for the info...I'll give it another day or so. I'm not to keen on the lag on wake=-up so I'll be shopping for a new kernel if it keeps up.
No problem, and on CM7, I have no issues with the non-sbc version of the Tiamat kernel.

[Q]Phone randomly shuts down using Virtuous Unity 2.35

For a few weeks i have been getting these total random shut downs of my DHD running the latest Virtuous Unity 2.35.
I saw that happening live 2 times on specific occasions/functionality calls:
1)After switching the DHD on and inserting the PIN to unlock the sim card...few secs and BAM....everything goes down. This happens from time to time.
2)Few secs after running the camera app...some loading goes on and BAM...here we go again...cell goes off
What the hell is happening, should i worry about the phone hardware or is it some wipe/format i didn't do properly prior to flashing the rom.
The problem is i noticed it also with other custom roms...but with those it never happened while i was using it, instead it happened getting the phone out of my small shoulder bag.
I am really afraid my cell has something wrong with the hardware...i was angry as hell and i tried to do some "heavy shakin" to see if the battery was not retained to its place as it should have but nothing happened...cell always on...
What should i do?
PS: i must say i tried almost 15 roms last 2 weeks but always used the related full wipe files/used a decent format/wipe procedure.
plz help me
---------------------------------------
Some tech stuff maybe you need to know
Device: Desire HD
Rom: (current) Virtuous Unity 2.35 (those days i flashed more than 10 roms, MIUI included)
Status: S-OFF HBOOT-0.85.2007 (CID-11111111)
Radio: 26.09.04.11_M2
RIL: 2.2.0131HM
Kernel: Stock that comes with VU
So that you know that's what i always did prior to flashing any ROM (currently using 4EXTRecovery 2.1.3 RC2) :
1)format system
2)format cache
3)format data
4)wipe data/factory reset
5)FLASH ROM
--------------------------------------
EDIT1: I noticed, just to keep you posted, that on the recovery menu the SD appear to be "not well partitioned", i don't know if it may be the cause.
Do you have app2ext working?
I'm guessing here. Try backing up your SDcard on a pc (preferably via cardreader) and giving it a thorough format with one partition only. You may need to delete the partitions first. I can't tell you how unless I know your operating system. If you continue having the shutdown issue afterwards you would be able to cross out SDcard problems at least.
Hi ROBINGAZI, thanks for your fast reply.
ehm, what is exactly app2ext?
I don't have a card reader right now, does it really change if I mount the SD via the phone? Anyways, i got a machine running WIN 7 x64.
hope this step will clear out the problem
Plug your phone to the computer as disk drive.
copy everything you have on the sdcard to a directory in your computer.
then click start>control panel>administrative tools> computer management.
a window will appear and you should see "storage"
in storage you will find "disk management".
you should be able to see your phone's SDcard there. right click and then delete the partition into unallocated space. Then right click and create a partition (fat32). format the partition.
if needed remount the sdcard to your computer (not the phone)
copy only one zip file (the rom you want to flash) to the SDcard (preferably something reliable like stock or something very close to stock).
unplug the phone and reboot into recovery. Do a full wipe...format everything apart from the sdcard if you think it is proper.
flash the rom and see what happens.
this way you can at least rule out the SDcard for causing your problems.
PS: Dont restore via nandroid...you could be putting the problem back into your phone.
BTW: Does your phone shut down properly or the screen goes blank like it would if you unplug a computer. Anyway make sure you dont just have a loose battery cover or battery before you try this out.
Thanks again.
Yeah my phone screen just goes blank like it would if you remove the battery from it while on.
I restored the SD card and it works properly. installed Revolution HD 5.2.6
As i stated earlier i also tried to shake the phone to see if the battery had some kind of faulty retention system but the phone stays on.
So i really can't understand what is the problem.
PS: I was curious, is there an application that tells you the entire life of a battery? meaning since when it started to operate?
NEW UPDATE ABOUT THE MATTER:
It's DEFINITELY the battery...i don't know why, i don't know with what criteria but it's the battery.
Yesterday i switched it with my brother's phone, obviously another DHD. Since then i have had absolutely no problem of any sort. He, instead, is experiencing random shut downs...
i think that the "problem is sloved" so to speak
the question about the battery app remains...or maybe there is a way to see the battery entire life cycle with a system file.

[Q] Host of problems after rooting and using CM10

After a couple of hours trying to find someone with the same problems as me I came up with nothing, so I decided to make a thread.
Firstly, I am no where near versed in device hacking so I am hoping these problems are just due to my ignorance.
My coworker rooted and loaded cm10 and teamwinrecovery onto my sprint GS3 and since then I have had a few issues. The most frustrating problem I am currently experiencing is the phone will not write anything to the external sd. There is no indication as to why this is the case. Under the storage option in settings it shows that it can read the external SD card yet programs seem to not be able to see that it is there. For example my camera will not give me the option to save photos to the external SD and programs like app 2 sd wont give me the option to transfer any of the apps to the SD card even ones that i know are supposed to work like Winamp. Also ive tried using DirectoryBind to change the directory of apps and music but I'm just prompted to create a new file because the data directory doesn't exist and asks if i want to create one. I tap yes and i am just prompted with the same error again and again.
My second main issue is when I dock my phone to my windows 7 PC I get an enigmatic problem. Either i get an error that says the USB malfunctioned and cannot be recognized and the SGS3 won't show up in mycomputer. Or, the default drivers install fine and the device will show up in windows. However, if i try syncing winamp or even dragging files over to my phone it will copy for anywhere from 1 second to 5 minutes and then windows will freeze and if i close the process it will crash windows and/or winamp. I tried installing the samsung usb drivers but then i just get a device ID error and it wont show up.
I was able to find some people with similar issues but not the constantly changing one i have. All the fixes that have been suggested have not worked.
I realize this is more likely an issue with my computer than my phone but when i was running stock it would work fine.
If anyone can provide some insight into these problems or can direct me to someone with a similar issue it would be much appreciated.
I really like CM10 but these issues are deal breakers for me and I dont really want to go through risking bricking my phone in order to try and get back to stock but i will if it will fix these problems.
