[Q] Nexus S not Booting

A few days ago my phone started acting weird as it would not boot beyond the initial Google screen. It was random behavior as sometimes it would boot normally but sometimes i would have to do a battery pull. Its a rooted phone which was running Cyanogen 7.
I tried booting into recovery to find that it was not mounting the SDcard and always shows the message "error mounting SDcard". After reading on some forums that it could be a CWM issue i was able to flash a new CWM (one which was more stable) as well as Cyanogen 9 but the problem still persisted.
The situation now is that i cannot get it to even connect to my laptop since the ADB drivers are not being installed on my Win8 even after unchecking the "check for signed drivers" option in Win8. Without the phone being recognized i cannot flash anything to the device.
I suspect there may be something with the hardware, as sometimes the phone does not even power on. Any help on this would be appreciated as my phone is just lying there. Which is provoking me to buy an S3

When you plug it into your computer does it show up in device manager at all? Also I don't know win8 as well as win7, idk if they kept device manager in there...

it shows as Android 1.0 but as i was trying to revert to stock rom and cwm using the Nexus Toolkit i removed any and all device drivers that had been previously installed as instructed by the guide in the toolkit.
I used was always able to see Android 1.0 while in bootloader but if i went into recovery it showed "Nexus" in the device manager, yet the recovery gave the message "unable to mount sdcard"

it cant find the device..just shows "waiting for device" nothing happens after that have to CTRL+C out of it. Here is what i think is going on and anyone is welcome to input their comments:
1. Windows 8 is probably not allowing the Samsung drivers to be installed which is why the phone always shows "!" next to it in the device manager
2. Once i am able to get the drivers in there i should be able to flash a new recovery since the one i currently have CWM 5.0.2.0 is causing the sdcard not to mount and i always get the "error mounting sdcard" when i try the mounts and storage
3. Once that is fixed i think i should be able to flash a new ROM

i use windows 8 and everything works, dont use samsung drivers use google ones.
check this thread made by me and try again:
http://forum.xda-developers.com/showthread.php?t=1901617

I think its your laptop not having the right drivers. I don't have a Nexus device right now (not sure why I'm posting here), but I think it's supposed to say something else beside "Android 1.0", which tends to mean the driver isn't correct. I wouldn't discount using Windows 8 as an issues.
But I have similar issues in the past with multiple Android drivers conflicting. When you remove drivers from the Device Manager, make sure to also check the box telling it to delete the files from the system as well.
Then use the Google USB driver, links in my signature.

[Q] Need help Re-Rooting

A few months ago I tried upgrading the bootloader to Jellybean and somehow things did not work correctly. I really don't remember how exactly I messed it up but at the moment I am stuck with a Unlocked Bootloader and on 10.4.2.9 US firmware unrooted. Any advise on to which root method will work? I had tried a few back when this happened but I kept getting errors. Also now I can't get windows to recognize the device either by using Asus Sync or any other Asus driver I have found.
Thanks

firstly you must install TWRP by fastboot.

That's the main problem I'm having now, no matter what drivers I install on the computer, Windows does not recognize the tablet. The driver installs correctly but when I plug in the tablet I get an error stating "There is a problem connecting the device to Windows" or something like that.

USB not recognized + no Recovery

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

Go to your system setting and select storage. Click the 3 dots in the upper right corner and tick the box which is Media device (MTP).. Good luck..

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:

In the Device Manager I have nothing under Portable Devices, but under USB devices it appears an Unrecognized USB Device and a bubble notifying about an unrecognized USB device keeps popping in the task bar. Even after installing ASUS Sync it is not detected.

You don't connect your tablet to the PC through the dock USB port, do you?? Just had that in another thread....
If you connect the tablet directly, I'm stumped. No idea why it's not recognized...

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..
Try the ones I have attached.

Had the same problem.I fixed it by uninstalling the faulty usb device. Then disconnected the usb cable. Reconnected. And the drivers installed.

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.

[Q] Problem rooting GT-P5110

I'm trying to root a GT-P5110 with Android version 4.2.2 following the instructions at http://forum.xda-developers.com/showthread.php?t=1980683
Odin seems to be running ok, but Odin doesn't seem to be able to detect my device.
When I boot into recovery mode, I have a menu on the screen with the items "reboot system now", "apply update from adb", "apply update from external storage", "wipe data/factory reset", "wipe cache partition", and apply update from cache". Do I need to select one of them? I took a gamble on "apply update from adb", but Odin still doesn't see the device.
Can anybody give me any hints on what to try next?
Thanks,

The drivers seem to be up-to-date (I installed them from the Samsung website yesterday. I'm using Windows 8 (not 8.1, which won't play nicely with my laptop) so maybe that's the problem. Time to dig out an older computer, perhaps.

(Incidentally, why do we need a captcha to post when we're logged in? I had to run through about 30 before I could find one I could even attempt, and the audio ones are even harder to decipher!)

You are doing it wrong.
Power on and push the volumebuton ( on the same time ) to the right.( UP )..and keep it that way til it boots up.
Than you get this screen
Then push the volumebuton to the left ( DOWN ), and then you are good to go

Connection issue with GT P5110?!
Hi Guys,
trying to stick CWM on my gt 95110. got it into download mode but windows is no recognising the device? Have installed and reinstalled the drivers many time but nothing works. I've used different cables, run odin as admin.
Running on Windows 7
Please help!

If you have Kies installed try removing Kies from pc, restart pc, reload Samsung drivers then with Odin started hook up tab to pc.
If not recognized still, while tab is still plugged to pc reboot tab, it should do it.
Pp.

Already tried that and have just tried again. No luck

More info, what rom, what recovery what Odin. Is tab working properly.
Did you try a factory reset?
Pp.

It's the most recent version of odin I could find. I'll check the version number late when I get home later. With recovery do you mean cwm or the stock recovery on the tab?
I have restored tab to factory settings and tried what you suggested again this morning. Windows keeps on saying unrecognised device your device may have a fault. Can't see why this is the first time I've ever connected it to a pc since I got it. Tried every combination of kies and drivers installed and un-installed. Been through all the windows help suggestions. Have contacted samsung support but they take a lot longer to respond than the good people on xda.

Many times this is a bad cable or USB port on the computer. You might try changing those just to make sure. Then if that doesn't help you might even have to change computers.

Try a different cable, try a different pc.
Have seen cable that works with charger but not with pc.
Pp.

Thanks, have tried 2 cables. One was the original cable that's been in the box since I first got it. Have tried all usb slots and will try my girlfriends laptop tomorrow. I'll let you know how it goes.
I've also got a support ticket open with Samsung and they have offered a remote support session to try to resolve. Anyone had any experience with them? Hopefully one of these would resolve this.

Tab 2 not recognized by PC

I installed some cyanogen rom on my tablet and now everytime I try to plug it into my laptop or PC It says USB not recognized device descriptor request failed. I tried with 3 different cables and 3 different computers. I have samsung drivers installed. I just need to get it to connect so I can restore my tablet to stock ROM. I was trying it on my own with mobile odi n(app) and tried to flash it but it went into a loop and deleted recovery. Now the tablet does power on and works - apps crash all the time and no root available. So basically its useless and I do now know what do to... Please, someone just help me out here >.< :crying:

Basically, because what you get is a CyanogenMod, which does not relate to any piece of the Samsung Driver. All you need is Google USB Driver which supports almost all Android phones in the world. A thread in XDA talks about 15 seconds Google USB Driver Program for Windows which can be found somewhere in the XDA thread world.
And more here, for the problem about root access, have you tried installing a SuperSu flashable zip through your recovery yet? That should work a lot. Then, if you update your firmware using recovery without using an OTA update manually, apps may not be compatible and will crash. Reinstalling all your crashing apps from the Google Play Store should help.
Finally, if you want to update your phone through recovery, not an OTA-received ROM, please make sure not to install many apps on it, because when it crashes, you can do nothing but to reinstall it. although, all add-ons (Such as GApps, SuperSu, Xposed Framework, et cetera) need to be reinstalled so you don't lose them during a manual update, so don't delete your flashable add-on zips once you installed, you might need them forever.
Recovery is like a mobile version of Odin, use a Desktop version of Odin so you can get yourself out. A tutorial might be found somewhere on YouTube.
Hope you have a good day,
Shippo

There is a tool called Forget Windows Use Linux in which all necessary drivers come preinstalled and your tab should be recognised from your pc with no problem if it's a driver issue. Try it

Try this slide down from upper left of the screen. If the window indicates charge only, click on it. It should then offer file transfer. In order to get adb to see the tablet turn on deveper options and enable USB debug mode. Hopefully that works for you.

there is something very very very very very old which is called cf autoroot
