Hi all,
My tablet is stuck at logo after installing Chainfire 3D and i cannot even connect it through ADB as it says Unauthorized or Offline when i type adb devices in command prompt.
Please help how can i recover my tablet back.
I didn't installed any custom rom, no recovery image and also don't have CWM recovery installed on it.
My tablet is rooted and has stockrom on it.
Its a MTK based device named as Qtab V8.
I know there is a thread about how to recover your fone after you installed chain fire but its all based on ADB and i am not able to connect to ADB as i told above so need help.

HELLO,
I have been trying to upgrade my Acer liquid e700/e39 from 4.4.2 kitkat to lollipop, so i have been trying to install philz touch recovery to my mac, which is running mac sierra.However whenever i get to the point that says 'this requires a working adb on your pc and a root shell on your mtk devices click ok, then it say's please wait a moment, then it says 'please connect your phone via usb, whenever i connect the phone and click okay it says "sorry adb root shell isn't working.But i enabled adb root on my phone via king root,and usb debugging is also enabled.I also followed some tutorials about installing adb and fastboot on mac x, and ran some commands via the terminal, but i still keep on getting 'sorry adb root shell isn't working with a yellow exclamation, and it then asks if i want to download some mtk tools which takes me to pdanet.I set up pdanet on the mac and on the phone from the instructions, but still nothing works.help!
thanks.
Hi,
I'm looking for some assistance to unbrick an Allview Viva P8 Pro tablet.
All this mess started from looking after some disk space to install more apps on on the default second partition.
First I've tried some tools like app2sd with no luck and finally decided to try adb/fastboot way, using a linux machine, to root the device.
Before starting the root procedure i was able to boot into recovery mode and while being into recovery mode I could see the tablet as a google device with the proper vendor id 0x18d1. Also "adb devices" command could find the device as expected. Right after issuing "adb restart bootloader", i cannot enter into recovery mode and it hangs with the logo displayed on the screen, i think it's a boot phase before entering into recovery mode.
I can still see it as usb attached device, not with google vendor id but identified as "Onda unverified", with vendor id 0x1f3a. Windows OS finds it as Android Bootloader Interface USB Developer and that's it. I've tried to install some drivers to establish communication but with no luck so far.
Thank you in advance.
Hello, I have unlocked bootloader and twrp installed. I used before a custom room from miui forums and it worked well but i wanted to try a new one so i wiped everything on the phone and tried to put the rom via adb sideload but it always fail at some point.
I can't adb push either because adb devices doesn't show my phone.
The last time adb push worked for me and my pc always recognized the phone before so I don't know why is not working this time...
Any ideas? Thank you!!
PS: Yesterday i could transfer the rom via adb push (adb devices showed recovery) but the install failed so today i wanted to try a new one but I just can't...
Windows Device Administrator shows the phone connected as Google Nexus ADB interface.
Ok, i made it.
I mounted only data on TWRP and then ADB devices recognized the phone.
I don't know if i can close the post!

Hello! I have a problem with old tablet it is Prestigio multipad 4 quantum 7.85. It is that this tablet doesn't have OS installed so I tried to install it manually with adb . In recovery I turn on ADB update and ADB with command "adb devices" detects it as "sideload" so I tried command adb sideload update.zip (I put it in ADB folder) which contains original software which I downloaded from internet but installation starts and after completion on tablet i see installation aborted. Tablet doesn't have TWRP and as I said only stock recovery is working is there any way to install software to it and will start working?
PS I'm not native speaker but I hope the text is understable
