So i have a motorola razr xt910 and i was running the jellywiz rom before this thing happened. So what i did was, boot into bmm recovery, restored cid, did a full wipe and immediately tried to flash the mokee rom. When it was done, i rebooted and got a FASTBOOT FLASH FAILURE. Later, i tried to use RSD lite to fastboot it back to europe ics but the com did not detect the phone. I tried lots of stuff
1. Tried another pc
2. Reinstalling the drivers
3. Tried different cables even the motorola OEM one
4. Spent money to replace the micro usb port on my phone
5. Factory resetting my phone a few times
6. I tried with my friend's razr on a pc with all the appropriate drivers, the pc could detect my friend's phone but not mine
But all of them did'nt work, it is still stuck in fastboot flash failure for 3 weeks now. Any solutions? Thanks in advance

I had a very similar problem- the proper cable was necessary for my computer to recognize the phone. I uninstalled all of my USB drivers, and let windows reinstall them. This has helped with my SGS3 for recognizing the device. I used RSD 5.7, and having adequate power is imperative.
EDIT
When I say I reinstalled the drivers, I don't mean the Moto drivers. I uninstalled my USB device drivers in Control Panel> Device Manager, and then I reinstalled the motorola device manager, which reinstalled the motorola drivers. However, if your computer doesn't even recognize an unknown USB device connected, then it sounds like either A) a USB cable issue, or B) a USB A port issue.

Sorry for the late reply and thanks for trying to help. Okay so I tried what you said, I uninstalled the USB device drivers and let windows reinstall them rebooted my pc then reinstalled motorola device manager. When i plugged in my phone, the pc still did not detect it although i was using a motorola oem cable fresh from the box. It is definitely not a USB port issue as I tried pluggin in my mouse and omy thumbdrive into the other ports and it could detect them and install the drivers. So any solutions? I'm starting to miss her.
Do you have access to the fastboot menu at all? Any of the options, aside from AP fastboot? What is the battery status?

I have access to the fastboot menu all the options available and the battery is OK. Its just that when i plug it in to the pc it does not detect the phone.
Will the PC recognize the phone under any of the other boot options? (BP Tools, diag, BP SBF flash, Recovery, etc.) When I got to the point where my power source was adequate, and all I had trouble with was PC-Phone recognition, I purchased an OEM Moto charger from Verizon with a cable that said "factory data" on it. I wish I could be of more help, but that was the last step to fix my problem. It recognized immediately, and I successfully flashed. It sounds like you've covered all your bases on the PC end. Let us know if you find a solution!

Thanks for your concern. The pc did not detect the phone in an of the other options so the last resort is using that cable. Is it the same as the factory cable, can i make one myself cause i have a soldering iron at home. Or ordering one online would be better?
I would say go ahead and make one. Just beware, a lot of USB cables (most) have either rubber or hot glue molded around, so it is difficult to expose the contacts on the Micro B connection. There is a great tutorial by MotoCache1, located HERE, that will give you the rundown. It's worth a shot. My only concern is that the idea of the factory data cable is to trick the phone into thinking there is a good power source (without a battery/dead battery). I would think that finding the right USB cable would effectively solve your problem, but go for it, and let us know how it works. You can order the cable (if TeamBlackHat has them... or you can find one sold out of Cali on Ebay, I've heard), and that may be the ticket. Good luck.

Thanks for the tip. I will give it a shot when I have the time. However I was wondering why my phone would run into such a problem. Before that when i flashed roms and soft bricked it, i could still recover it using rsd lite and fastboot files. Secondly, my usb cable was woking fine until just before i landed into this mess. The phone could not be detected by the pc in usb storage mode so i resorted to using google drive instead of actually solving the problem.
By the way, could i have the model number of the motorola oem factory data cable you bought. I dont live in the US so i may need to buy it from another shop. Thanks!
You may very well have a hardware problem, if you were having connection problems before the fastboot errors. Could be the contacts on the micro female in your phone. It sounds like you definitely have a data transfer problem if you couldn't mount for mass storage.
The only number I could locate is SKN6430A.

Appropriate USB cable, unfortunately. Motorolas are very picky. Even if you weren't having problems with a particular cable before, like me (fastboot flash would start, but not finish, first time I encountered a problem), the right cable solved my it. OEM Motorola data cable.

Okay I guess it all goes down to the cable. I've got a SKN6378A from motorola but it doesn't work. So what is the appropriate cable i should get or should i just send my phone to the motorola service centre and ask them to help me solve it?
I'm certain they can diagnose the problem, though I couldn't say for certain what the cost would be. You may have better luck purchasing a used phone on eBay. I can understand your frustration, to an extent, though you're problem is turning out to be more complicated than mine! Motorola tech support may also be able to help, remotely.

fastboot not detected
while the PC recognize the phone under any of the other boot options BP, Tools, diag (here the phone goes black), BP SBF flash, Recovery, why the fastboot is not recognized? im on a xt910, i have no system.. and i remember that previosly, he wasnt able to be recognized even as an mass storage... so weird.. then i messed up, and i cant do nothing because all the do able thing is via fastboot.. is there any chance to do something via recovery stock without getting operation aborted?.. oh, another hint, i mess a little with the entry of the female usb on the xt910, and now i have an "unknown device" maybe is broken.. and if i disarm it, and i cut a cable, and green and white should be data, maybe ill be able to flash something via rsd.. damn is so weird that the bp is recognized in rsd but fasboot not.. and i cant buy nothing, i just have a knife, two cables(i cutted one to put the negative positive directly to the battery) and wi fi. thanks in advances, and yes i know that is an old thread, but i dont know what else to do. /And sorry for my english, i dont speak it.

First of all I am a big-Noob.
My LG optimus one P-500 is in stock ROM.
My Problem :-
Earlier USB was working fine but now
when I plug it in to the AC Adapter it charges OK but when I plug it in to the USB after that it only charges and neither the Phone nor the PC recognizes the USB data connection.
I have tried
1) Power off the phone and remove the battery for a couple of seconds and power it back up, after doing this the USB does not connects. Not even recognised by PC or Phone
2) Device manager also does not detect anything.
3) Uninstalled modem driver and reinstalled USB driver but no result.
Please help
Thanks in advance

Dear mates
I have really very high respect for the forum so please help me out.

This happened to me twice before. I had to send it to LG's Service Center because I saw no way of fixing it since the computer wouldnt know what to do with it...
If you have custom recovery installed, you might be able to flash an original ROM over it. This wasn't an option for me before and it seemed like the only way to fix my phone. Don't take my word for it though. Try for the service center first if possible...
Did you try going to settings and choosing Mass Storage only?
Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)...
Before going to any service, do a backup and Factory Reset your device, then try again...
Oh, and disable LG modem from Device Manager after installing the USB drivers.
USB not getting detected
I am trying in choosing Mass Storage only.
"Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)..."

I will try this definitely but going to service means 3-4 days without phone . really very scary .

anymore help
Okay , I did face this problem before and I did about hundreds of advice from my friends but this is the step that works.
I discovered that this happens when you do crazy **** on your sd card with applications such as titanium backup or root explorer. Curiousity kills the cat.
Firstly you need:
1) Usb Card Reader [Of course which suits with your sdcard]
2) Computer
Firstly, you want to dismount the sdcard from your phone and mount it to the USB Card Reader.
Connect the Usb Card Reader to your Computer.
You should be able to gain entry to the sdcard
Next,clear everything on your sd card then place your sd card on your phone back and do a factory reset. If you don't do a factory reset then you must do it all over again if you decided to connect the usb to the phone. After reset-ing the phone , try to connect your phone to the computer. Congratulations.
Note: This works for me but it doesn't meant that it will work for you , but I think that this is worth the try.

Ur phone charges through usb that means your phone usb port/usb cable is ok. Do this :
Uninstall the drivers, restart the pc and try connecting the phone again. Remember not to install the drivers again. Win7 save a dump of old drivers and i think it will auto detect it. Post results here.

None of the above methods worked on mine as well - same results on different cable(pc/os).
Will try to flash rooted original firmware via custom recovery, del custome recovery and root and send it to service.
Please take the time to read this:I flashed and installed SkyRaider a couple days ago and I noticed when I connected to my PC that my PC started recognizing it as HTC Phone (or something of the like). This apparently really screwed up my drivers on my computer because I installed iKReaM and now I can't even get into disk drive mode...it doesn't ask what connection type I want anymore and my computer just says "USB Device Not Recognized". I tried uninstalling the HTC Driver Installer but that didn't do anything either. This is not good as I ran into the same problem when trying to root my friends Samsung Fascinate and never go the problem fixed. Anyways...my phone worked perfect before and SkyRaider evidently messed it up pretty good...to say I am pissed is an understatement. If you need any more info please let me know.
Please link me to the newest HTC Drivers as well, it would be much appreciated.
If no one can help I will have to do a clean install of windows 7, which is not an enjoyable experience

You will have to buy the pro version to push files. That would be your easy solution.
You can always use recovery to get into usb mode as well.

I can't get into recovery anymore using usb mode, computer doesn't recognize the device so no way to use it...and I would use the Wifi app instead of using a usb cable?

I know this isn't your actual problem but just for the record, AirDroid lets you control your phone and push files to it with a web browser and wifi for free.

When you plug your phone into your computer does the phone start to charge?
If so restart the computer and plug the phone into a different usb port. Check device manager and see if you have it listed in your usb devices, or you have an ! over a usb. Most of the time this ends up being an issue with the computer it is being hooked to, not the phone. The computer isn't launching the driver correctly to show the phone that it is connected to a computer, and not just a wall outlet.
Even when I've had this issue, which is random I have still been able to use recovery usb to manage it. Make sure when your in recovery you mount the sdcard before enabling the usb.
My friend's got a Legend with a USB malfunction (which I'm supposed to repair ). I've gone through all the threads and posts, and I couldn't find anyone which had precisely my problem.
When the phone's switched on and connected to via a USB cable, it starts charging, and the pop-up to select Charging, Mount as disk drive, Sync etc comes up.
But on the computer, whether I try USB debugging, or Mount disk drive, or the others, it shows the error "USB Device not recognized". I've installed HTC Sync, and am able to connect other phones without any problem.
I tried connecting the USB in fastboot, but it doesn't detect it either (FASTBOOT doesn't change to FASTBOOT USB).
I just wanna confirm with experts if this' a problem with the hardware (Got a sample here :http://forum.xda-developers.com/showpost.php?p=18420923&postcount=11) before I go to the service center.
Thanks
U might be using the wrong data cable. There are 2 different types, there is the old type that only has 4 connectors in the mini USB plug (phone end), the new ones have 5 connectors.
Another possibility is that the cable is simply just damaged.
I had the exact same issue with an external HDD that worked, then stopped then worked again then stopped, tried a new cable and worked without issue.

Hey guys, long time reader thought I'd contribute my frustration to hopefully help someone in a similar situation.
I spent a few days wondering why I couldn't get any of this to work no matter what cable I tried. For some reason, my HTC One X didn't like dealing with fastboot through my computer's USB 3.0 slot. When I finally tried a 2.0 slot on the same machine, everything went through just fine...

Not unless you are already rooted. Does the PC not recognize that you have plugged it in at all or does it just not load the drivers correctly? Best way to tell is to open your Device Manager and plug in the phone. the DM should reload and show something, whether an error or not. If it does not blink out and reload when you plug / unplug the phone, then it's either a hardware issue with the phone's USB port, a bad cable, or bad USB port on PC. And it is possible for a phone to charge correctly, but have issues connecting to a computer if the data pins are messed up. If it IS the phone's port, the repair isn't that bad and could be handle with some patience and simple tools as this one does not involve soldering. You'd need this:

As you say, the PC dosn't recognize that the phone is plugged at all, I try all the usb port on my laptop, different cable, and even different laptop and the same problem keep comming up.
I tried also to reboot in odin mode to see if my laptop detecet anything, but nada, nothing in the DM.
Also, like you expect, it can charge but no data connection, and whene it turned off and I plug it it automaticly turned on by itself.
I pretty convinced that it usb port is screwed.
So, to install a rom my phone have to be rooted!! no way to root it from the recovery mode?!

You can try to clean your USB port of the phone with some compressed air, in case some pocket lint got in there too. Doesn't take much to mess these things up, unfortunately. But yea, I doubt there is a way to root it in the stock recovery as most Samsung phones don't have this option. It'd take less time to just fix it probably then figuring out how to jump through all the other hoops to find a way around it.
So... now that I think with hindsight, I did something pretty stupid, and I'm going to need some help, since I have no idea what to do.
I have a Nexus 9 tablet, and I never liked it. The OS is just so slow and laggy, and it overheats, and it has many other problems. Quite a couple of times, I installed custom ROM's and so on, and I never had a problem. Let me explain what I did now.
Around a month ago, while looking on the internet, I heard this thing that if I install the original software, but with no encryption, it would work better. It sounded cool at the time, so I downloaded the Nexus Root Toolkit, and did it.
Everything went well. But then I heard about a custom ROM that was apparently working even better, Dirty Unicorns, so using the same toolkit, I installed it. For the first time, my Nexus 9 actually worked the way it is supposed to work, but the custom ROM still had its problems, it crashed from time to time. I was thinking about possibly returning or selling the tablet, so that's why using the Toolkit, I reinstalled the original software. But, if I went all the steps, and also locked the OEM, my device then showed a flag saying that it was a development device, while booting up. So, after messing around with the settings of the Toolkit a little, I decided to reinstall the software, but leave the bootloader unlocked.
But after some time, I reinstalled my Windows, and I also reinstalled the Toolkit. But that's when I started to have problems. My tablet wouldn't connect to my laptop anymore. I used the toolkit and uninstalled drivers, reinstalling others quite a couple of times, and that's where I think that I messed something up. I managed to eventually connect my tablet, and I rooted it, after rooting it, I connected it again. But adb wasn't working for some reason. A little annoyed, I simply copy pasted the zip file of CM13 into my tablet's internal storage, and I rebooted it to the recovery, TWRP. But the recovery failed to flash it, saying something about an Error 7.
Now that I think about it, I was stupid, since after that, I performed a complete factory reset, resetting my TWRP backup too. I tried to connect it again, nothing. It didn't connect at all. I plug it in, my computer doesn't even recognize that something is plugged in. No Nexus 9, no Android Device, no anything. I booted it in fastboot mode, and it worked, my computer recognized it, and after I downloaded a ROM zip file again, I tried to connect the tablet back and flash it manually, but nothing. It didn't recognize anything anymore.
I tried to reinstall the drivers countless times. I deleted what I had, reinstalled it, nothing. I uninstalled and reinstalled the Toolkit. But strangely, now, even if I know that I installed the Google USB drivers, and the ADB drivers, as I even installed Android SDK, if I use USB Deview, it doesn't show me any of them. I can't see any Google or ADB drivers, although I tried installing them multiple times. So now, I'm stuck with a tablet with TWRP and no OS, which I can't connect to my PC, and I can't use ADB or fastboot.
Is it something from my laptop? I can't check to see if it will connect to another PC right now, so I don't know for sure. Is there any way to delete all the traces from my (failed) attempts at reinstalling the drivers, and to install them again properly? Or is it something from the tablet itself? I don't have an OS, so I can't enable USB debugging.
So, shortly, I have no idea what's happening. And I'm quite obviously a noob in all of these. Can anyone help me? Please?
If you boot into the bootloader and from a command prompt type fastboot devices you don't get anything?
Sent from my Nexus 9 using XDA-Developers mobile app
I still couldn't get ADB to work, but I managed to work out fastboot. It may be something from my USB cable, it works perfectly.
I flashed the original software back, and I'll go to check my cable, although I feel kinda stupid that I didn't think about that in the first place.
Thanks for the help anyway.
If fastboot is working and bootloader is unlocked, you can still install a factory image.

https://dl.google.com/dl/android/aosp/volantisg-mob30p-factory-ae9ce05a.tgz
Extract the files and put them into the same directory link fastboot and execute the flash-all.bat
WARNING: Any data will be erased!!! Also TWRP
Now it should boot up with stock firmware.
If you want your device decrypted install twrp. format the internal storage and flash the pure nexus rom which i can highly recommend and is decrypted by default. Dont forget do flash gapps
my issue is same

Use fastboot, not adb.
what if fastboot isn't working, either?

Is the tablet in fastboot mode?

Yup. I can boot into the bootloader, and from there (or from TWRP) into fastboot, but no computer I've connected it to (and I've tried many) will recognize it. Doesn't show up in Device Manger or lsusb, doesn't show up from either "adb devices" or "fastboot list devices" (the latter just hangs there saying "Waiting for any device"). The USB on the tablet itself is fine, and I even replaced the USB daughter-board just to be safe.

Hi, uberSkeptic...
Just a quick thought... Have you tried a different USB cable?
Rgrds,
Ged.
Edit & Additional...
The command is not fastboot list devices... it's fastboot devices
One last point... Ensure your Nexus 9 is definitely booted into fastboot mode and not just HBOOT (the bootloader). Take a look at the two screenshots below - your Nexus 9 should look like the screenshot on the right, the one with my green explanatory text.
Apologies for the poor image quality; there's no way of taking a screenshot in the bootloader, so I had to take photographs instead.
Hope this helps and good luck.
Thanks for the advice and going so far as to photograph the hboot/fastboot screens, but unfortunately I have indeed tried multiple USB cables, including the OEM's and I've definitely successfully gotten the tablet into fastboot but it doesn't show on the computer with either fastboot command (devices or devices list).

I'm out of ideas then.
One of my first thoughts was possible Windows driver problems, but as you mentioned you'd tried it on several different computers, that didn't seem to be a likely cause of the problem - I mean, you'd expect at least one of 'em to work! Maybe somebody else can help with a solution.

Sadly, me too. I even tried using a flash drive with a micro-USB connector on it, which I used to use to do nandroid backups, but now TWRP doesn't even "notice" that the USB drive is there (or any USB drive connected via an OTG cable).
Too bad, too - the tablet is otherwise in great condition and even has a custom-painted backplate (long story).
Thanks for trying to help, though!

Mmm... (scratches head, raises eyebrow quizzically)...
If I was Hercule Poirot and this was a murder case, and with all the suspects gathered in one room, prior to revealing a brilliant deduction... I'd be casting very dark glances in the direction of your Nexus 9's USB port right now as the likely culprit here.
Think about it. Different computers. Different USB cables. An OTG cable... And none of them work. What's the one thing they all have in common?
Answer: The USB port on the Nexus 9 itself, and where you've replaced the USB daughter-board.
Maybe, possibly, that replacement don't go so well. Maybe there's some unknown problem with it. I can't comment too much on this, 'cos it outside the scope of my knowledge - I'm a software guy; circuit boards and dismantling devices to fix 'em isn't something I'm comfortable with. I always think I'm going to damage something or rip a wire out somewhere, so I bow to your superior knowledge in this area, as I may be talking complete cobblers here. It certainly wouldn't be the first time.
Anyway... Sorry I wasn't able to help find a working solution for you. If anything occurs to me that might help, I'll be sure to let you know.
Rgrds,
Ged.
I would be suspect if the replacement as well if it weren't for the fact that I did it only AFTER the other symptoms/problems appeared. Hence the replacement (which is known good because the battery charges no problem). There cables and everything inside the tablet tests just fine... It feels like the firmware for USB is somehow corrupt or something.
Thanks for all the advice, though. ?
So I can't believe I didn't think of this before, but when I run "dmesg" from the terminal app included w/ TWRP, I see that there a TON of errors, mostly referencing problems accessing the recovery image. I could screenshot it, if anyone at all might be able to tell me a little more specifically what the dmesg log is trying to tell me...
