Every thing was fine while my nexus s istalled CM10.
But after I install CM10.1 M2,I lost my USB connection.
I get the following when the cable is connected: "USB device not recognized".
I tried on different computers and usb cables then got same "USB device not recognized".
After I google that, They said install an app called "USB Switcher". Open it and clicked change to mass storage
and reboot. Then my computer still said "USB device not recognized".
I found the cyanogenmod official forum. There was a man got same proble. I post my story.
but did not get reply.
I thought it may be a bug with MTP transfer mod.
But I did got more information about that.
I thought it may be a bug for CM10 ,but now I intalled CM10 MOD from CM10 M2 TO RC5. Still got same thing.
So I come here for help.
Thanks in advance for any suggestions.

i son't think it's rom related, i had the same issue with others rom, i asked here but nobody answered me... anyway i found that if you pullout battery then go in recovery fix permission and reboot it starts working again... i think it's some kind of error in the file system, propably the best solution would be to format the partition deleting all data on SD... i'm not able to understand what caused this, one thing i did, but i don't know if it's related, was using LAGFIX and trimming system and data... u can try to mount USB from recovery and see if that works, what recovery are you using ???

Hi Kriout, I am unable to access my phone from my computer for about a week now. Earlier it was working fine. I tried resetting the usb ports by uninstalling and re-installing them. only once myphone (Nexus s I9020) is recognized as an unknown device but Windows 7 unable to update the drivers or find them for this device.
If I want to even go back to stock rom ( I am currently using Avatar ROM 4.2.2(android) ) as i am unable to access my phone via computer.
I tried going back to older updates of Avatar Rom to see if its the ROM which might be the issue, but that didn't work either.
I tried mounting the USB/SD via the bootloader but no use.
Can you help me please?

- you should first try to understand if it's a driver problem or a smartphone problem, try to mount USB on other pc
- if they doesn't work you should try to mount it in recovery, use TWRP, an old CWM ( in the last one this function doesn't work) or the philz recovery that u find here http://d-h.st/users/philz_touch/?fld_id=16784#files, try to fix permission, wipe cache and dalvik and pullout battery alos several time if it doesn't work. i found out that for me pulling out battery entering recovery fixing permission, shut down, pull out battery entering recovery and mounting USB often worked... you can try also using different kernel,
- my idea is that the problem is an error in the SD file system so propably the best solution could be formatting the unity from the smartphone itself. i still didn't do it but i made a good cleanup of all folder, even the system file and system folder, leaving jjust music photo and download...
- if everything works in recovery but not in the rom, it could be a kernel or a rom problem, so first change the kernel, if doesn't work make a clean install of something else ... i'm using MIUI v5 with marmite 8.7bigmem and for now everything started working again ...
Thanks

Here's what i Did. I did install Philz touch recovery. Its very useful. I also installed the Nexus Root Toolkit (NRT). Using NRT I launched the USBDeview. Using this i removed all the google related drivers from the system. I then restarted my phone is bootloader mode and restarted my system as well. Now my System was trying to install the nexus S drivers but unfortunately it said that the device in disconnected. But then in bootloader mode i put the phone in Mount USB storage mode and VOILA i was able to see all my files. I did take a quick back up . But still in the normal mode i was not getting the USB Storage prompt. Now i went back to the bootloader and did a factory reset. and then installed the Latest Avatar ROM. and now I am able to access the Phone storage through my computer.
I am not sure if i had deleted some files by mistake or some other issue. And thank for referring the Philz Touch Recovery. Its great.
Now am thinking of installing the Stock ROM for NEXUS S back on to my Phone. Do you think its a good Idea?
Thanks for all the help mate.

i don't think the stock rom is the best rom ... it depends on what you need ... by the way what is your data transfer rate ( into the SD )??? me in recovery get a good speed with a lot of spike, it transfer data at 5 mbs with spike of 15 and sometime go to 0 ... when i mount USB on the rom i get an almost constant 1.5 mbs that is reaaaaaaally slow ... if i test the write speed using the phone it returns me a normal speed...
p.s. when u say u mount USB in bootloader, u mean on recovery ?
Trying to get my mk908II up to 4.4.2 and saw that shinny 2.0 on KitKat Finless ROM 2.0 over @ http://freaktab.com/forum/tv-player-support/rk3188-devices/beelink-tronsmart-t428-mk908-etc and thought that must be the latest/greatest and flashed my mk908II with it, everything worked "fine" but no wifi or bt, now I'm thinking the 428 in the name = screw-up.
So on closer look MK908-II - Finless 1.6 ROM seems to be what I wanted, now how to get thar from har? Settings only has usb debug, no connect usb, so how do you connect via usb? Second method sd card update while holding update button gets twrp recovery not bulit-in update, is their a way to use the sd update, or can I flash from within twrp? None of the files seem to be zip updates which is the usual twrp update method??
Tried booting with the 4.42 sd rom and get at it that way, it has the "usb connect" but no usb debug, no dev. options at all it seems, so the computer sees it as a usd drive but not in the flash tool. Maybe I can copy the correct wifi drivers to the nand from here? If yes, any ideas on what exactly needs to be replaced??
Any guidance?? Thanks
Hi everyone, I ran into a serious problem today with my S6 G920F. I was running stock android 7 with Magisk and TWRP installed, I flashed the firmware using Flashfire from the Google Play store.
This morning the phone decided it would stop charging, a problem I faced with Android M. Anyway I reflashed the firmware package but this time i chose NOT to select the options to inject supersu and save my custom recovery, thinking that I could get it back to stock and re root it from there.
The phone previously would not boot if either Magisk or SuperSu was not installed (after i rooted it), it would just endlessly loop. Unfortunately this was the case after i flashed the firmware .
I assumed it would be a quick fix as I could just use Odin to flash the stock firmware . Unfortunately I was wrong again: my computer gives me an error message "USB Device Not Recognized" no matter how many times I uninstall and reinstall the Samsung Driver, Odin wont detect the phone either. Even Smart Switch is at a loss. The phone is currently plugged into my PC and is charging normally, I CAN boot into stock recovery and download modes.
SOMEBODY PLEASE HELP!! :crying::crying::crying:
Seems very obvious now but I found the solution I found the original cable that came with the phone; plugged it into the PC and just like that the computer registered that it was a Samsung devices and started installing drivers right away, seems like the P8 Lite cable I was using isnt a data cable?
I was able to flash TWRP using Odin and flashed Magisk using TWRP. All is well
hey everybody!
i was using my galaxy a3 2017 (SM320FL) for half a year with lineage os (15.1) and flashed the latest build (Lineage 15.1-20180821-UNOFFICIAL-a3y17lte) some weeks ago.
i allways noticed little bugs etc. but all in all it worked for me.
since a week now, the phone won't boot into the system anymore if not connected to charge. i can still boot in download mode and recovery without plugging it in but not into the custom rom. as soon as i deconnect it (when using the custom rom) it reboots and gets stuck at the samsung screen.
that wouldn't be that bad if the usb connection was not dead as well. that happened a few month ago allready. i tried to connect it via odin, kies and smartswitch in download mode and recovery. but nothing. i also reinstalled the drivers via kies. i also flashed "ressurection remix oreo" to check wether it works with different roms but it didnt.
does anybody here have an idea what i can do to make the usb connection work? or is there a possibility to flash the firmware without it?
device SM-320FL
Android 8.1.0
TWRP 3.2.3-0
Bootloader: 0x030c (?)
EDIT: i guess this thread is supposed to be in the device-forum but i'm not able to move it myself am i?
EDIT: the problem turned out to be broken cables. i tried with a third one and usb is working fine.
Hi all who read this, after I flashed lineage and gapps and magisk,there was some error message for magisk. So I went to the system clearly after that, and I had to root my phone so I went again to the twrp, a weird message said hello to me. It was about modification something so I first time saw that and didn't care for it actually. then I saw that internal storage was totally deleted and everything with it. I couldnt flash any roms because there was none. All I can reach is fastboot and twrp. But, they are not working very well either. Couldn't see my device on pc with command adb devices, couldn't do adb sideload via twrp, then I bought a otg cabel and it didn't work either (my usb port on opo is working). I can't mouth the usb otg choise in twrp. So I was working for it for 2 days for saving my opo but couldn't. Can anyone help me with this problem please?
