[Q] Tracer Ovo 2.0 bootloop and windows drivers problems - Android Q&A, Help & Troubleshooting

Hello. I've got a polish tablet Tracer Ovo 2.0 yesterday. Today I was trying to switch nand flash memory with sdcard in the vold.fstab file. Well, I screwed up something and now I have a bootloop on tablet's startup. I was trying to flash stock rom using Batch tool, but when I connect my tablet with pressing vol + button, Windows ( 8.1 ) can't detect this tablet propetly. It's driver comes up with 43 error, so I can't really install stock rom. Also, I can't install new drivers, because when I try to, Windows is saying that I have the latest drivers for this device (wut?). When I turn of my tablet without pressing vol + button, Windows is detecting this tablet as mass storage, but I can't really do anything with it, because of the tablet's bootloop. Is there any chance that I could flash the system, or get to the vold.fstab file using my pc and correct my mistake that I've done in that file? Please, help. I'm a big newbie and guides on the Internet can't really help me, since I can't install any drivers to this tablet now.
Oh, and I'm not afraid of my battery status - charging is working.
Sorry for my english, hope you'll come up with something and help me.

[Q] I can't power off my TF-201. It reboots always in recovery(clockworkmod).)

Hello to everyone.
I have to say sorry for my English(I'm Spanish). So, I have a big problem. I have a transformer prime(TF-201), with CyanogenMod 9 and in the last update, I go to the recovery by pressing the power off button an selecting the reboot in recovery mode.
So, I install the 09052012 update and then the GAPPS and then wipe and all fine.... but, when I press the reboot option, the transformer reboots all the time in the recovery... And I've tried with all options and nothing. The recovery don't have any power down button or something like that, so I NEED HELP guys!!!!
I have using CyanogenMod since the CyanogenMod 7 for my galaxy sII... But with this I don't know how to do.
And now, when I try to install a .zip with the recovery, It says that It can't mount /sdcard/
Thanks!!

There is a file in the developement section you can flash if you can push it to the tab. Search for recovery bootloop in that thread.
Thanks, I'm going to try with this... I will tell you if it works.

Think you need to use the naked drivers..

Thanks. When I go home, I will try to do that. So I only have to install these drivers in my PC, and then connect the tablet and use de recovery bootloop no??
Hello...
I've tried to install this drivers, and I think that I did It right, but the PC don't recognize the tablet.
I delete all the old drivers from PC, then I connet the tablet, windows update searched for drivers, but It doesn't faund them. Then I went to the hardware administrator(or wherever you named it) and found "Transformer", I update the drivers with the naked driver's folder, and It looks like It's all right, but the PC doesn't recognize the tablet by now...
What I did wrong??
Thanks for all of your patience...
Sounds like you're in better shape than I am. Device manager doesn't even detect my tf201. :\
As long as devmgr is showing "Transformer", right click--->Properties -->Update drivers, then browse to the folder where the naked drivers are located.
Hope that helps.
Well, that is what I did, but with drivers installed, the PC do not recognize the TF...
I'm going to try usin linux...
I need help!!!
I got the same problem! I bought an asus prime off ebay, and I tried to restore it to factory settings. Now I'm stuck in recovery mode "ClockworkMod v5.8.1.8" I can see my Tablet as "Transformer" in Device Manager, but when I right click on it to install the driver from "Universal_Naked_Driver_Beta_0.6.2" I always get this error: Asus Transformer Prime ADB Interface: The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering. I need help with this! I've been trying everything I could for the past few days, and nothing seems to work! Thank in advance

brick
you now own a brick if you flashed an incomplete rom package.......you need the fastboot files, etc yada yada from who ever makes that tablet....then maybe just maybe you can turn your beautiful new brick back into a little android man once again...
I guess I cant post the stupid link but google android SDK tools and go to that website and download the tools and install the basic package for your tablet and make sure google usb drivers are checked when downloading it all.....you need that google driver so you can install it on your windows system so your computer can read the tablet....anyways do that install driver in windows device manager under that unknown device and then reboot everything and you should have a generic android driver now installed..............you flashed root so you never set up SDK so im guessing you don't have a clue as to why you bricked your phone but hopefully this will help.....if you do unbrick it then you have to use that link you posted....his stock rom and flash that over what you have on there right now and you should just stop trying to flash stuff until you have a clue as to how to fix the device BEFORE you start.....

HELP Bricked Tablet Ematic EXP8

Hi, I first want to say I am very thankful that you're reading this.
My problem is tablet ematic exp8 just suddenly got bricked .
When I hold power off + volume up or down button, the tablet turns on and doesnt offer me options and only goes to android logo again.
So I have downloaded ematic exp8 image file and usb drivers from their website. I followed some advice and tried to install those drivers but windows said that current version is up to date.
I tried to put image files on SD card but it didnt work.
I tried with LiveSuit but it didnt recognize my tablet.Althought he recognized IMG file.
I feel like usb driver might be the problem since USB debugging is turned off and in device manager Alcatel Andorid ADB interface is listed as driver.
If you have any suggestions please say so.

[Q] Problem with flashing Allwinner A13

Hey guys,
Recently I ordered the Allwinner A13 (Q88) from DealExtreme. I wanted to flash a custom ROM onto it, but following all the guides I still can't manage to get it. First of all, I noticed that the firmware it came is 4.2.2 Jelly Bean, as opposed to 4.1 as they had written on the site. Anyways, I managed to get the storage drivers (computer can see the device and I can put files onto it), but I'm not sure about ADB, because the computer says nothing when I connect it in debug mode and it just makes a noise that a USB device is connected. I tried using LiveSuit to flash it, and after watching some guides that tell you to hold down the volume + key and press the power button 6 times, I found out it only works when I hold down the power button, and even when I do that it says that the USB device is not regognized (error 43). I have Windows 8.1, but I tried to do the same thing on my Vista laptop, and after I do that there, it connects and disconnects, and says that the device was unplugged. I wanted to know, how can I flash it? Is it a driver problem or the tablet is just faulty in that matter? I tried using Uberizer and that doesn't find my device as well. I would really be thankful if someone could help me out, because I want to install a custom ROM. Thanks!

Help sony Xperia Tablet Z SGP-321 will not start possible wipe internal storage

Good evening everybody,
I have a big problem somehow my Tablet z SGP-321 got a complete wipe of the internal storage (don't know how, if through stupididy or technical mishap). Is there anyway that I can get it back to functioning? I can get a red LED on the Tablet and every now and then with luck I can get it to boot showing the Sony image but then it shuts off again. I can't even get the pc companion to recognize the tablet furthermore the repair option of the application. can somebody help me?
Thanks in advance

ok I have downloaded the flash tool and android 4.4.4 and I tried to flash but I can not get past the window where it asks to connect the device to the computer using the vol. down button (apparently it is not detecting the device) i have also tried the blu funtion which also is not functioning.

it seems that drivers are not installed needed for flashmode/fastboot.
