[Q] "Usb connected" vanished - Android Q&A, Help & Troubleshooting

Hii devs
These days I can't get my phone connected to my pc neither mounting my sdcard. I tried that even through my recovery, in vain ( I've got TWRP Recovery & root).
I got alcatel x'pop 5035d. I tried a fresh install with One touch upgrade, a backup with flashtools. Can't recognize my phone ( ps: I got all drivers installed and fine since I tried that before. )
Then i'm stuck with the annoying unkown device from windows, unable to mount my sdcard, and even a factory reset didn't change a fact.
I hope you can help me to figure either is a hardware or a software problem, and help me get through this problem.
Thanks

You can't mount your SD card on your phone? Did you try formatting it?

USB Storage Damaged

So i was about to check something on the internet by using 3g data, but for some reason the 3g wasnt working, so i thought id refresh the phone by giving it a fresh reboot.
Upon doing so, after the phone fully rebooted, i got a notification in the notification bar 'Usb Storage Damaged' with sub-text 'Usb storage damaged. It may need reformatting'.
I have checked and i can access everything in CWM recovery, so therefore backing up the stuff i want/need shouldnt be a problem.
My question is, that is there a way to fix this WITHOUT reformatting?
Any help appreciated.
Thanks

Ideally copy off the data first so you have a backup then run chkdsk in Windows as it's FAT32.

Hi, I have a similar problem on my unrooted S2.. I have read that using chkdsk in Windows on an unrooted phone wont work (and didn't when I tried). I don't mind rooting, though I'm not sure if I could even do this while there is a USB storage error. I have hours of recorded lectures on my phone, and exams coming up soon so I am desperate not to reformat if possible!
I've been using my phone without USB storage for about 2 weeks now trying find a fix, and I guess this is my last hope, so any help would be greatly appreciated.

Thanks for your answer , But when I connect my phone to the PC and choose USB storage ,all I get is grayed out I and J drives.
how do I preform a CHKDSK? I tried running CHKDSK.exe but it doesn't seem to do anything (it says it's in read -only mode) .
EDIT:
I got it ,it's working again ,a couple of restarts and connecting \disconnecting to pc solved it.
as for CHKDSK.exe I copied it to the sd card and ran it from there.
thanks a lot
Hi,
I have a similar problem...
My SGSII battery ran out and when I started the phone after recharge, it started to give an error that the internal storage is damaged and also stopped to recognize the microSD card.
The microSD connected to the PC it is recognized and does not accuse error with chkdsk. I tried to format the MicroSD (on the phone) and then to mount it, but it does work.
Also, connecting the phone to PC in mass storage mode simply shows teh drive letters, I can't access the drives.
I did not want to format the internal storage before be able to copy my data, and I think the problems are related.
I managed to mount and access the internal storage using the terminal emulator (running on the phone) using the command
mount /dev/block/mmcblk0p11 /sdcard/
But the rest of the system does not recognize even after this procedure, and I don't know the command to do the same with the MicroSD; or copying data to a PC to then try to wipe or factory reset.
I've tried to reinstall the ROM with ODIN and did not solved the problem.
Also tried to install CWM recovery, but it can not mount / sdcard (gives error).
Could anyone help me?
Thank you!

[Q] Can't see sdcard in recovery mode.

Hey,
I've flashed Omega 33.2 and Siyah 1.8 kernel.
I used 5.5.0.4 CWM recovery (didn't change the recovery, just flashed Omega and right after Siyah).
I then flashed something from Omega kitchen that I guess made some problems with the ROM, so I got in a bootloop. Not a problem - I will just flash the rom again and everything will be ok, but unfortunately I deleted the rom from my phone memory. In those situations I just go inside recovery and mount the sdcard, so I went into mounts and storage -> mount /sdcard, I connected to my computer (windows 7) but nothing happened. So I tried to install kies, but it didn't help too. I also tried the same in Ubuntu (maybe it's mass storage and not MTP because from what I know linux doesn't support MTP), but it didn't worked.
I end up taking my external sd card, putting the rom on it, and flashed the zip from the external sd card.
I don't want to do it every time I want to put something in my phone through recovery. How can I fix this problem? (Yes, I tried more than one USB slot and cable).
Thanks in advance!

Thanks for your reply.
Tried TWRP, CWM touch 6, but it didn't work. I tried to mount external sd card and it didn't work also. Tried windows7, ubuntu (I think it's mass storage so it should work), and another computer with windows7, but didn't work in neither of them.
Also, tried 'adb devices' when the phone is plugged in in recovery and it didn't see the device too. Does adb suppose to work when I'm in recovery? (I'm developing Android apps so I'm sure that adb is 100% working when the phone is on).
In CWM 6, I press mount /sdcard and after I press the text is still mount /sdcard (doesn't change to unmount), and when I press mount /ex-sdcard it change to unmount /ex-sdcard but doesn't appear on the computer also.
Does anybody else is facing the same problem? very annoying :S
Nobody faces this problem too..? :/
same issue here!!! trying to get some help as I don't have an SD card available right now

[Q] HTC Sensation XL External memory missing

Please help me. it's been almost two weeks i'm having this problems. my phone is HTC Sensation XL CM10.1
the problem starts here, when i switch on my phone, it stuck on CyanogenMod, i restart my phone so many time but that wont help me, so what i did was i format my phone from bootloader.
so new problem appear again
I'm having problem with my EXTERNAL MEMORY. this is not SD CARD since HTC Sensation Xl DOES NOT have memory card slot. it's HTC Sensation XL 16GB.
my problem is everytime i enter camera and gallery, it says "No external storage available" then my whatsapp also cannot download images and videos. then when i go to storage, it shows only internal memory available, it does not shows the External one, it seems like the external memory is not inserted.
i already restart my phone so many times but still this wont help to solve the problem. then i go to recovery, then i tried to mount sdcard, but it said "cant mount Sdcard" then i tried to format sdcard but failed since the sdcard cannot be mounted.
then i try to connect my phone through USB to my computer, but i cant even read the sdcard, theres no notification that my phone is connected through USB. but its connected already. lol. so confused.
if i cant connect through USB, then how can i solve this problem? how can i flash a new rom? how to downgrade my phone since i hane read from most of the forums that the only way to solve is downgrade the phone to stock. but i cant even connect it through USB to put the rom.
im just telling this if this can help you.

boot into Recovery
-> Connect your HTC SXL to your PC
Go to "mount USB Storage " and sty in this menu, now the PC have to format the SD-Card -> But please look that it only show you the 8 GB free space (SD-Card). I know that Windows can show you only this one but with linux it is able to format everything.
So i had formated the SD-Card
-> Download CM
-> Download Gapps
Copy on the SD-Card
Reboot to Recovery
-> Install ZIP from SD-Card

[Q] Connect mass storage via CWM recovery

I've recently flashed my phone with Nemesis kernel using Flashtool, and installed "MoonBreaker 3.5". Unfortunately it is horribly, horribly broken so I have tried to do a full wipe and reinstall. This also failed to work, and somehow wiped my internal storage, so now I have no kernels or roms available on this phone.
The phone boots, but the market doesn't work, downloads app doesn't work, there is no file explorer and no network connection. The phone will not mount as usb storage when booted, or when in CWM recovery. When booted it gives me an "MTP USB Device - Failed" message after attempting to install drivers (win7 and winxp). When in CWM it does nothing at all.
Therefore my question is, how on earth do I get files onto my phone now?

What model of phone do you have? I had the same problem with the Sola (I insanely forgot copy .zip on sdcard before flashing bootloader) and i solved copying the archive on external SD then with CWM selecting Install zip from external sd. Of course this method is not valid if you have Xperia U. In this case or in another case where you haven't any external SD slot try reading this guide.
I have an Xperia P, sorry the forum denied my edit for some reason. Thanks for your ideas!
I've had some success booting into fastboot then, while it's connected, switching to flash mode. Stock kernel reinstalled! Thanks for your help!!

USB file transfer not working...

Hey,
if i connect my phone with my PC, i can normaly see all files,...
But if i want to copy a file from my computer to my phone (internal or external sdcard) its stock at 0%. (in system and twrp)
After a while (2-4minutes) windows says, that was an error with the transfer. After these message, the phone reboot (twrp)
I tried to reinstall the right usb drivers, tried sideload and adb push but.
i googled the problem, but i cant find something like this.
sideload says something with "cant read comand"
and push says its done (800mb file after 10sec :/ ) but there is nothing on the device.
I dont know what the problem is. the phone is from 2012 but EVERYTHING else is working fine.
sorry for my english

Did you tried with another computer ?
And if you really can't fix your problem you can also use micro sd card to transfer file.
