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.

Hi there
That did not help.
The problem happened after I upgraded CM10.1 CM2 from CM10.1 CM1.
What I did is that just wiped data,cache and install CM10.1 CM2. Then I lost USB connection.

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 ???

How to use this Philz Touch recovery?
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 ?
Hello everyone ! I will try to explain my problem as clear as possible, hope it will be solved.
-Samsung galaxy GTi-9300, this was rooted few months ago.
-It was working fine until I uninstalled touchwiz using Nobloat app. Now, nothing besides SAMSUNG appears in the dark screen. I am not able to do anything or see anything else.
-Being smart, I connected phone with pc and opened kies , but pc/kies do not recoginise the device.
-Then tried to unroot the device, where I failed again.
So, my question is how I can install touchwiz in this case? Or any other soloution ?
ps: (there is no micro SD card in device, no back up etc )
Great thanks in advance !
Was your usb debugging turned on? or do you have a custom recovery like clockworkmod or twrp? then you can install a launcher.

I guess it wasn't turned on and custom recovery you mentioned were not installed. But there was Titanium backup installed, if that helps ??
So if you put the device in download mode, does ODIN recognize it? If so, you should be able to restore to stock from there. Your data may be lost though if you are unable to obtain files from the internal storage.

Guys I got it solved.... thanks ! I am not tech/IT guy but managed to solve it with the help of other posts in xda forums.
Morning all,
This is my first post, and I know this may have been asked a thousand times, however, I have searched the forum before asking this question.
I decided to root my Sony Z3, but have now ran into 'serious' issues.
I followed the steps to the T, or thought I did but now have a Sony phone that is stuck on the SONY load screen, and will only boot using TWRP and with only TWRP installed, and no OS. When I connect this to the pc, the only folder in internal storage in the TWRP folder, everything else has gone.
I managed to install Android Studio, the SDK, USB driver and also platform tools. I have also successfully installed TWRP, I also tried to install SUPERSU, but this completes in about 2 seconds if that, and then I'm back to square one.
Luckily there is nothing in the phone I actually need, no pics, files etc. But I have tried to install custom roms with no luck. They always fail, I can get as far as copying this to the phone, using TWRP to install, then it shows the no MD%5 file found, or that it's for D6603 or whatever.
I've clearly done something wrong, and I'm not sure how to recover this, if indeed I can at all. i'm assuming that since I can boot into TWRP, it is fixable, but there is no OS, and i'm struggling to install one.
Even though I think I have installed SUPERSU, when I re-boot it says your device is not rooted, SUPERSU is not installed?
Any help would be highly appreciated, and apologies if this has been asked a million times before.
Cheers
Jay

Ok man... relax.... it's not serious .
If your bootloader is locked , install PC Companion and *simply* repair :good: ( Or you can use flashtool to flash stock ROM )
If it is unlocked , lock using flashtool and repair with PC Companion .
This is a mild type of soft brick . As I can see , you didnt backup before trying to install the ROM , right ? ALWAYS , ALWAYS backup before installin anything root-related to your phone
Hope this helped :laugh: Good Luck and remember , that's not serious , it's just a little softbrick

-no rom/os on phone
-computers(multiple) wont find my phone
-since nexus 5 no sd card slot or otg
-twrp working
-was running cm13
main problem. i wanted to install a new rom on my phone so i deleted the old one, so i could put the new one on. then i realised i did not have a new rom on my phone. so i went to connect is to my computer and it could not find it. so now i have a phone that can boot into twrp and nothing else. i did a full wipe of the system.(every single option available in the twrp options)
how do i get my phone back since i cant put a new rom on my phone since i just cant drag a file on it from my computer. since there is no other way i can put files on my phone. it is not because of lack of drivers. since it used to work just fine. i tried multiple computers to be sure. all of which in the past i could access my phone on.
One of the advantages of adb sideload is to solve this kind of situation.
adb push should help too. Your device must be into the recovery mode.
Other solution: download the factory images and flash everything but userdata.
Please only post a thread once, use the below. Thread closed.
no rom and no connection with my computer

Hello guys..
I really have a problem right now! I appreciate everyone who tries to help me. I´ll try to expain what exactly is my problem with my Mate8.
Also I´d like to apologize for mistakes of gramatics, because im acutally from Germany..
So, my phone was working right, and actually everything was okay. With time it got so slowly, because storage was full with datas and so on. I tried to clean up some things to get it again a bit faster and so on, but that did not make it (at all). Also windows wont recognize the phone anymore. When plug in the USB it didnt even asked for data, charging or photos.. also I had problems with charging, it took toooo long for a few %.
I was on "KANGVIP" Rom (as much I know i changed stock to this custom rom) https://forum.xda-developers.com/mate-8/development/rom-kangvip-slim-t3318572
Time passed untill 3 days I decided to flash a new rom normally, like put rom on sd card, wipe dalvic and cache, and so on. I wanted this rom; Lineage OS https://forum.xda-developers.com/mate-8/development/6-0-1-cyanogenmod-13-port-t3512985
But everything came up with different errors for different actions I did like this:
"cant mound sd card"
"cant mount inernal storage"
"cant mount data"
"cant format data"
"cant mount system"
"cant mount cache"
etc. etc...
I tried to change file system to EXT3. EXT4, EXT2, FAT, and so on, for Data and System. Nothing worked correctly (but I had still on some Filestystems instead of 0MB like 2700MB). Still not working correct... On TWRP.
Then I tried to update TWRP from 3.0.1 to 3.1 (new one released). Because I saw, more precisely, I heard that an update can fix this mount issues I had.
Said and done, I updated it and instead of 3.1 I had 3.0.2 (idk why but I didnt care). But still theese problems happend.
So then I saw in a Video on youtube (which I cant find anymore) that another recovery like CWM can fix this issues. So I downloaded CWM recovery.img and installed it with TWRP an rebooted to recovery again. And now I´m in a situation, in wich I dont know what to do.
Now the phone tries to start, but no OS installed.
Try to get into Recovery, but no recovery aviable exept eRecovery which is failing with data when trying to restore.
Problem is also that Fastboot and ADB is not working. Installed HiSuite, ADB drivers, Samsung drivers (though could help).
Tried Knife Italian, but no connection to pc..
Tried different cable, no luck.
Tried windows 7, 8.1, 10 Home and now im on Win 10 Pro 64x.
All I can do is to boot into Fastmode, but cant do anything. And when I try to boot the phone normally it stucks on "Your device is booting now..." because no OS...
PLEASE HELP ME GUYS! I REALLY NEED THAT PHONE :crying::crying::crying::crying::crying:
THANK YOU !!! :good:
Hallo,
If your phone is still recognized in fastboot mode, you can try following up my tutorial here » https://forum.xda-developers.com/mate-8/help/how-to-unbrick-l29-al10-stuck-fastboot-t3599775
I was experiencing the same problem. No OS, no recovery, no fastboot flash possibility, only fastboot booting. Keep in mind that you will need 15€ for this method to work but it is the only way to resurrect your device.
PM me if you need further assistance.

Thank you for the reply my friend.
The problem is, that it only boots in to fastbootmode, but any pc wont recognize it. I tried even with Mac...:crying:
Greetings
DC-Phoenix should recognize the fastboot brick state even if the device doesn't show up in Minimal ADB & Fastboot. Try my method and let me know if it works.
Hi guy's.
DC Phoenix save my mate 8 with factory firmware.
I was the same problem like you and search one week a solution and after I decided to pay and try Phoenix and now I write from my mate 8
Before buy 15€ of credit you can download and try to connect your phone on DC Phoenix
does the DC phoenix method take your phone to absolute stock? ie, stock firmware +recovery + Locked + no root?
Yes. You will have the factory firmware (stock) but with unlocked bootloader.
