I just rooted my A510 and ever since my laptop won't recognize my tablet. What can I do? I've tried factory reset, as well as flashing cm10/other roms. I downloaded the os from the acer website but don't know how to flash. Can anyone help me out?
Recovery= cwm
rom = cm10 unofficial
Update I was able to flash back to stock with unlocked bootloader and recovery from the acer website. But still I cannot get any computer to recognize my tablet. I have also lost root. What can I do now? Charging works perfectly so micro usb slot is not messed up.
Did you try another USB Cable ? another PC ?
What's no working ? MTP ? USB Mass Storage ? ADB ? Fastboot ?
Yes I've tried different USB and computers. The problem is that the computer won't recognize tablet in any mode. I'm currently on stock recovery with stock ww jb. I have us version of the tablet. Also update. zip not working in stock recovery. Idk if this is related but this problem occurred after unlocking boot loader also cwm would not mount ext SD. Boot loader is still unlocked. Maybe locking again will fix?
Edit: When in fastboot mode I am able to get usb device not recognized error in windows but have not been able to get it to recognize the device. I have tried pointing driver to acer official drivers but windows rejects these drivers. Device shows up as unrecognized device under device manager in windows and tablet fastboot mode.
Edit2: Windows gives same usb device not recognized error as in fastboot when plugging in using debug mode. Still no solution to this problem.
anybody know how I can fix this? Maybe flashing bootloader again can fix problem? Someone please help!

yes, you might try to flash all the Firmware using Acer ADT and a full Firmware file (BIN)

This sounds more like a Windows issue. What version of Windows? The Acer drivers only support Win XP or 7. If you load the Android SDK, those drivers can be made to work. If the USB on the tab recognizes a flash drive, I say look at Windows to resolve.
Also, I believe that once the bootloader is unlocked, it cannot be locked. It maybe can be replaced with a locked one using the fastboot flash command.
Acer Drivers are compatible with Windows 8 x64 (I'm using it)

How would I do that? ADB doesn't recognize the device neither does fastboot. Idk if it is a windows problem since I have tried updating drivers over and over again. I get an error returned saying usb device not recognized. Also I'm having trouble flashing in stock recovery. I put update.zip on root of sd card and external sd but nothing works. External sd doesn't show in recovery.
I'm now having trouble getting the pc to recognize the tablet at all.

I would suggest making a Linux thumb drive (http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows). You don't have to futz with drivers as much in Linux. All ADB and Fastboot commands are available. I used it for my phone and my TF101. An old 2GB USB will suffice.
Any utilities, files, etc. can be placed on the stick for use, as well.
so basically I should boot my computer using a usb drive then connect my tablet to another usb port correct? Also I'm starting to think my usb drivers in the tablet itself are messed up from trying to root. How would I fix that? But I will try what you said first. Thanks
Btw I am unrooted now cuz I flashed Acers stock firmware but it didn't lock bootloader which is weird.
I have tried using the usb stick to boot into linux but that would not recognize my tablet as well. My phone was recognized immediately but my tablet was not. The tablet won't even recognize that a usb is connected when it is connected to the computer, but shows charging when connected to charger. Again I think the usb drivers in the tablet itself are messed up. What can I do?
Do you guys think I could possibly do something in APX mode? Seems like it may be my only hope
anybody?

If you still have the USB adapter, try connecting a USB stick to the tablet. If the tablet mounts the stick and you can view files, then there is most likely nothing wrong with the tablet USB. If not, then Acer may still be able to help with a warranty claim. I bought the extended warranty w/ mine.
As I stated earlier, once the bootloader is unlocked, it can't be locked... perhaps replaced, but not locked.
If the USB functions, boot to the Linux stick and run ADB usb.
then plug in the device to see what happens...
Pretty much all you can do in APX is flash the factory image. that's the most primitive state for android devices...
http://forum.xda-developers.com/wiki/APX_mode
You would still need a functioning USB port.
Hope this helps.

I tried plugging in the usb drive with the adapter and the tablet was unable to recognize the usb. does this mean that the usb drivers are bad? What are my options? What happens if Acer denies me support due to being out of warranty?

Sounds like a hardware or physical problem. Inspect the contacts on the USB for an obstruction or a misaligned contact. There are 5 contacts on my A700. I would power down before messing with it. Also, check for a loose socket... you did say that the charger works, though.

Yea the charger works perfectly fine so I don't think that is the problem. It may be usb drivers in the bootloader or something cuz this problem started right after I unlocked the bootloader.
I contacted Acer and they said my tablet is out of warranty and to fix it it'll cause $250. Is there anything else I could try?

I really don't believe the USB driver was changed when you unlocked the boot-loader. If you replaced the Kernel, that would more likely. This is resolvable by replacing the kernel with stock...doable if you can flash from recovery.
Again, I say inspect the USB contacts. they are really tiny and delicate. If one is crossing another, this can cause your issues. They can be straightened with a lot of patience.
It would be very hard to find the USB port for sale as it is unique to Acer... with the 12VDC capability.
Thanks I will carefully look at the pretty itself. I did not change the kernel before the problem started occurring but did flash cm10'1 to see if that would fix problem amd it didn't. Thank you very much for all of your help!

Long time listener. First time caller.
I have an issue. My tf101 lost the ability to transfer data about week ago. Meaning, its not detectable by computers or any usb device
The tablet was rooted but i returned to stock in an effort to fix the problem and lost root.
I have tried:
3 cables
4 PC's
1 linux box
The tablet charges fine and even trickle charges from usb ports
I narrowed down the problem to a partially corrupt bootloader. Or simply a bad flash(team rouges rec and revolution rom)
I think i may be able to fix the problem by flashing ClockWork recovery, but i need to get root access. Any ideas or am i just screwed?
So im screwed right?

No, you're not "screwed" You could always just download an over-wifi file transfer app. I'm not sure what the best ones are on the Play Store, but I'd do you research if you're gonna drop a couple bucks on one. I haven't bothered since my Skyrocket is Samsung and I already get Kies Air.
I would suggest after flashing ClockWork recovery trying out some other ROMs and kernels and seeing if that fixes your problem. I would also highly suggest Team Win Recovery Project. It's been my favorite recovery so far, not to mention the touch screen interface is fantastic.

I assume you can still get into APX mode? If so, I would try running this. It's what I initially used to root my TF101, and it doesn't require you to use your installed recovery. Basically it roots and installs CWM recovery from a script run from your computer. Let me know what happens.

Well, I'm assuming that this is no longer on stock firmware and/or too old to be still under warrantee. The only thing I can think of, unless someone else here can give you an answer, is that it may be a hardware problem and you'd have to send it in to ASUS to get it fixed.....

My phone died and requires me to flash boot.img in order to bring it back to Android. To my surprise, I couldn't get it to go, and after some testing it seems my USB port is having an issue where it won't connect data, but will charge. Both of my computers with seperate USB cords are stating that the USB device has malfunctioned. Does anyone know of a good solution? I know there are the pogo pins on the back, but I don't know if there is anything that connects to them or if they transfer data. Is my only option at this point looking for someone to do a USB port repair for me? Any ideas would be very welcomed. Thanks!

You are trying to go into fastboot, right, and not just regular bootloader.
Hi All,
It has been a time that I unlocked my TF700t then followed the CM10 documentation to install 10.0 using CWM.
Recently I wanted to upgrade to 10.1 but it didn't work and ended with my tablet rebooting undefinitely.
I reverted then to install back the ASUS stock Rom from their website :
- I downloaded the file
- unzipped it (since it contains another zip)
- put it on a micro SD
- Booted into CWM
- installed the zip
I ended with a working tablet on the stock rom JB 4.1 but know I wanted to try again CM but I cannot access recovery anymore. I can access the bootloader but when I select RCK I get the droid laying on his back with the warning sign.
I thought I would need to flash another recovery (TWRP or other) using fastboot but now when I plug the tablet to my PC it keeps telling me that the device is not recognized. I tried to install the USB driver but it doesn't get detected.
Can anyone please help ? The tablet is working but I am afraid that it has lost some of its capabilities.
Thanks

What Windows version are you running?
You may have to uninstall the drivers for your MTP device before installing new ones as well as disabling Windows to automatically install drivers for a new device, then manually point it to the Universal Naked Drivers folder.
Or downlaod Android SDK tool ad through it the Platform Tools and USB drivers.
BTW: When you flashed the stock firmware you lost your custom recovery. That's why you see the dead Droid - it's the stock recovery.
If you can't get fastboot to work you can use Motochopper to root your JB 4.1 stock firmware and then GooManager to install the latest TWRP recovery.

I have tested it on WinXP, Win7, Ubuntu and another box with Win XP. Always same thing the device is not recognized.
When I try to update the driver and point it manually to the naked drivers it cannot detect them.
I guess that even for running Motochopper I will need to get USB working to be able to root my device.
Any help please ? I am stuck with a sluggish stock mod that buries the perfs of my device.

Then it's a driver problem and it's solvable. What do you see in Device Manager under Portable Devices with your tablet connected? Did you uninstall the driver and re-install it?
Did you try to install Asus Sync (which should give you compatible drivers for the TF700)?
So many driver problems lately... there's got to be a pattern to it, but what it may be beats me :what:

Sounds like a windows driver issue to me. You need to force windows to use the right usb drivers. You normally do this by upgrading thenm in device manager. You may have a borked windows installation to fix as well..

Im having the same problem and after one day of research I could not find a solution. I bought a use TF700 with a standard andriod on it, no mod, not unlocked, no root. When I connect it to the pc I get the same error, meaning just a USB Device showing up. Tried different PC's with different types of OS, no success.
Did you manage to fix the problem ? I would really appreciate some help because now I can't use that tablet in debug mode to test my android applications and that's all I bought it for. By the way, is there a adb tool that works wireless and doesn't neet root access or can I get root access without connecting my pad to my pc ?
Thanks for the help !
Well did you install adb fastboot drivers on the PCs you tried? Did you try it under Linux? Do you have the original Asus cable you connect it with?
adb over network is an option under Developer Options in Omni and Omni based roms - at least the LP roms. I don't think you can get that with an app you install. Probably needs to be baked into the kernel.

First of all thanks a lot for your response, didn't think anyone would still react on that post because it's quite old. Yes I did install adb fastboot drivers, the device only shows up in the usb section saying usb device not recognized. I tried nearly every driver I found, installed the Andriod SDK, the Asus Sync Tool, the naked drivers... then removed them all (including the hidden ones) and installed just the adb fastboot -> no success. I have not tried it on linux, but on windows 7, 8 and 10. Android version is 4.2.1 and Build is 10.6.1.14.10. I now unlocked it using the apk provided by asus (version 7 , 8 did not work). Still for rooting I need pc connection, so I ordered a new cable today (cable is original Asus though).
I installed the Rom Manager and that tells me the ClockworkMod Recovery and TWRP are already installed. I also tried that recovery (power + vol) and got the same result as nacef meaning " I can access the bootloader but when I select RCK I get the droid laying on his back with the warning sign." Thing is, I don't know what the previews owner did, so it might be the reason he sold the Tablet. Can I get anywhere form that Bootloader ? Maybe boot as a Superuser and then use wireless adb to root the device ?
Thanks a lot for your help, Im feeling that I have wasted the money and the only way to get rid of that feeling is to fix the problem
Grab the Puppy Linux live CD from here: http://www.transformerforums.com/fo...t/46090-guide-adb-fastboot-linux-live-cd.html
It has adb fastboot already installed. If you don't get a connection with that one the problem would be tablet side, not Windows related.
I booted using that Puppy Linux and followed the Guide but no success. After entering "adb devices" I get the output "list of adb devices attached" and than a blank space. So I tried booting in fastboot like you described in your guide and entered "fastboot devices" but that also gives me nothing. Fastboot works though (as it's already included in that image) so I tried a bunch of other fastboot commands but that just results in "waiting for the device".
I don't know what to do now, it has something to do with the tablet itself. Im waiting for the new cable but don't think thats gonna change anything.
You are not trying to do this through the dock port, right? You are connecting the tablet directly to the PC?
The only answer I have left is either a broken cable or one of the pins in the port is bent or broken. Get a magnifying glass and check them out.
Hey there, guys and gals,
I'm having a bit of an issue here, and it's somewhat serious.
The issue is as follows. I have Android 5.0.1 on my Nexus 5. When I connect my computer to my laptop... nothing.
Nothing at all. It doesn't show up in device manager, not even as unknown. Fastboot doesn't detect it, nor does ADB. I can't do anything, and it's scaring me. I don't know how I could have broken it, but I need to know how to fix it.
I'm happy to do whatever to get it working, so please help...
Update: Tried to factory reset, to see if it would fix the issue. It's stuck "Erasing...", and won't go further. I'm afraid my phone may be hard-bricked... Is it possible to reflash these using JTAG, and if so is there anyone that can assist with that process?

Is it stock or what? are you rooted?
Also , keep in mind that the factory reset can take up to 30 minutes.
IMO it sounds like a busted cable/usb port on either side / incorrect drivers.
Edit : JTAG is not possible on our devices , access is locked from the chipset itself.
Are u on Windows 8.1 if so I had a problem with Windows thinking that my phone was a acer and I had to go the driver settings and manually tell it that it was a ADB USB connection then it would connect fine also could be USB cable I found the nexus 5 to be very picky about cables
Sometimes I get that but it solves by going into dev and checking and unchecking usb debugg, but sounds more like a busted usb plug
Have you considered that you may be using incorrect drivers on your PC? This issue can be caused by having improperly installed drivers.

Also , keep in mind that the factory reset can take up to 30 minutes.

Right. I'll address you all at once for ease.
Firstly, the USB connector functions fine. My USB-OTG cable still allows me to access files on a flash drive.
Secondly, drivers can't be an issue in this case. It won't even enumerate the device in device manager. As if the phone simply isn't plugged in.
Thirdly, Win8 isn't the issue, as I"ve had this phone connected to this computer many, /many/ times.
So it must be a problem within Android 5.0.1
But here's the problem. In order to install anything else, I'd have to install a recovery. In order to that, I need root. In order to root, I need USB. I'm lost, guys...
I just had an idea does towel root work on 5.0 if so u could try that?

Hmm... That might work. I'll take a look. But if it succeeds, then something gets broken later in the process, this thing is a paperweight, right?
Edit: According to http://forums.androidcentral.com/an...29-rooting-nexus-5-towelroot.html#post4125236 Towelroot will never be possible on Lollipop. I didn't go much further than that though...
Ya I just read that to bummer
Edit: as of now there is no way to root without pc sounds like u may have some sort of hardware failure I'm guessing only way to fix is to send it in and that's 150 bucks min

Well... This happened when I updated via OTA (after reinstalling the stock recovery) to 5.0.1 after 5.0. I did this all over USB. Immediately thereafter, it quit. I got it to boot, btw. The erasing problem fixed itself, and it's now running, but the USB is still stuffed. This is sounding more like software than hardware. Almost as if whatever chip talks via USB lost it's own firmware somehow.
Cable or driver 95% sure. Did you try connecting it to a windows 7 /linux pc ? And ... u can never be sure but try connecting to a usb2.0 port. I had those issues when I accidentally plugged my cable in my frontal panel ( usb3.0)
A few months ago I had the same problem, my phone got not recognized by adb or fastboot. I played around a whole day with drivers and stuff like that. At the end I found a post on the internet describing that not all USB cables are able to do adb connections and I should try the original USB cable that came with my Nexus 5. So I looked for that particular cable and hey presto it worked right away.
And 2$ usb cables do break over time. They might still charge , but one cold solder joint and no connection

So you are correct. I didn't see that in your post, my bad.
Have you tried with another cable maybe?
Make sure you have either MTP or PTP checked in Settings/Storage/USB computer connection.

I've tried multiple cables. I KNOW that this cable is fine for ADB, because it works fine for my other devices. All of them. I may be marked a newbie on the forums, but I'm really not one. When I first signed up for this account I was, but that was in what... '07?
I've tried:
Drivers (Obviously won't work.)
Cables
Rebooting
Factory Reset
Different Computers
Linux
Windows
Switching USB connection modes
Toggling Dev Mode/Debugging on/off
Nothing works. It HAS to be a software issue on the phone. I don't think anyone read it, but it's almost as if the IC that handles USB connections has lost it's firmware. I don't think that can happen, honestly, so it must be whatever's in the ROM that TALKS to that IC that's causing the issue. Problem is, I don't know how to fix the ROM without USB connection and Fastboot.

Its unlikely that the ROM will be the cause if the USB port suddenly stops working.
Do you have a custom recovery?
If not, then not much you can do except send it in for repair/replacement.
Hi guys,
Two weeks ago, I decided to try another rom, as I often do.
I booted into the recovery, formated everything, and got the rom ready on my computer.
However, when I connected the usb cable to the phone, nothing happened. Strange, it had no problems before. Tried another PC and a few other cables (the original one too). Nothing.
The phone only charges but isn't recognized by any computer (it doesn't even show up in the device manager and there is no sound). The drivers are ok, it worked before that.
I also tried an otg cable with the rom on a usb drive and it doesn't see that either.
I thought, "great", my usb port data pins must be dead so I ordered one. I'm so lucky that i got a DOA one. (this one isn't even charging the phone)
So now I'm waiting for a new one or a refund.
Do you know any way to transfer a file/rom to the phone that has no OS (it boots fine in the recovery - twrp) without using a cable?
Thanks
I'm not sure of the finer details but can't you do it via fastboot. Or at least I would imagine you could install stock rom this way. ??? Like I said I'm no expert just a guess.
Good luck.

Do you know a way of using fastboot without a usb cable?

You cannot use fastboot without a USB connection to a computer.
Maybe there is some dust or dirt in your USB port. Try using some compressed air to blow it out, or try taking a small plastic knife or something similar and scraping it a bit. Once your computer recognizes is, then you can proceed.
It is possible that a windows update or something messed with the drivers. I would uninstall the drivers and start over.
