Hi People,
I have a serious problem.
I have a chuwi v17hd tablet (1st gen, as it doesn't have volume buttons)
This tablet now constantly boots into recovery, but I cannot select any options from the menu since I don't have the volume buttons.
When rebooting it only comes back to recovery.
I can connect with it using ADB but that's more or less it, adb shell doesn't work.
Fastboot also doesn't recognise the device,
Any tips are highly appreciated,
Thanks,

I have TnT Lite 4.4.0 on my tablet now and it is working fine with no issues. I want to install the new honeycomb OS on my tablet but I can not get into recovery mode.
I get the "Recovery Key Detected" in the upper left corner of the screen while the VS Birds logo is on the screen then it got to the next screen w/ gtablet logo, then a black screen loads with a box and status bar, then NOTHING it resets.
Any ideas?
Here are two ideas to consider:
1) are you trying to enter recovery from a powered off state? And are you sure you are holding the volume Plus key and pressing power? When i first got the g tab, I was messed up by the volume Plus and minus keys.
2) while fully booted into your ROM, can you connect to the tablet with ADB? if so, you can use the "adb reboot recovery" command.
Hope this helps.

[GUIDE] Restore G Tablet after a Failed Recovery Mode "update.zip"
Hi all,
My problem is this:
I have a 10'' chinese tablet without any type of identification, serigraphy or brand in it, and neither in its box. It hasn't any type of special feature like standard USB or RJ45 interface to use it to search its model.
The tablet is stucked loading in the Android text screen, so I can't use ADB shell to control it and do a factory reset.
I enter in recovery mode with the Power + Vol+ buttons, but the tablet hasn't menu in recovery mode, so I can't do a factory reset this way. The tablet have only 3 buttons (Power, Vol+ and Vol-), and I tried all possible combinations that I've seen in all internet sites (I've spent hours trying it).
ADB shell don't work in this mode, and this tablet doesn't have bootloader or fastbot mode, neither download mode.
The microcontroller is an AllWinner A10.
Then I have an unbranded unidentified tablet that doesn't boot and that hasn't menu in recovery mode... Someone can help me in how to restore to factory defaults this sh*t? ¿Or maybe I have to use it as chopping board?
Thanks in advance.
Hi again everyone,
I am trying to get ubuntu touch onto a tablet. I now have a rooted zeki 8" TBDB863b for this but I have run into an issue.
I can not get into the bootloader. I have a feeling it is because I cannot enable/disable fast boot which I cannot find either.
Holding power and volume up while booting brings me to the recovery screen. adb reboot-bootloader just reboots the tablet normally, same with apps that claim to reboot into bootloader. Fastboot options is not in the battery part of the settings, and there is not a power section to the settings.
So any ideas on how to get to the fastboot option and how to get to the bootloader?
Hello guys,
I'm new and i'm not sure if i posted this under the right place but here goes... (let me know if there is a better place to post this to get help with this problem)
Anyone who can help me revive my device will be given $5 Paypal as a token of appreciation.
I own a Onda v989. A Chinese brand tablet that imitates the iPad with some impressive specs for the price.
Long story short, the tablet came preinstalled with some bloatware, I root it, and used Titanium to backup & uninstall some system apps, which eventually cause the tablet to pop up "unfortunately the process com.android.systemui" non-stop (when i click on ok, it will pop up again, not letting me do anything on the device). I tried rebooting, and as soon as the lock screen comes on, the same error keeps popping up, not letting me do anything. I can not go into settings to factory reset or go into Titanium to back up. The device is not set to usb-debug.
I was hoping i could boot into recovery mode and factory reset from there holding power + volume up (i tried power + volume down too) but either combination seems to do anything (it doesn't even boot if i held power & vol + or power & vol - and only seems to boot if the power button is hold by itself). Once i reboot the device, the cycle of "unfortunately, the process com.android.systemui" starts again.
Could anyone help me solve this problem so i can use my tablet again, specifically, if possible, to boot the device into recovery mode using the buttons. If that's not possible, any alternative to restore my device? If you need additional details, please ask away!
Thanks so much!
I really hope my device is not bricked ;/
you can directly boot into recovery through adb "adb reboot recovery" or "adb reboot fastboot" and factory reset the device.

you can turn on USB debug from pc android.stackexchange.com/questions/112040/how-to-enable-usb-debugging-in-android-if-forgotten-pattern-for-screen-unlock then reboot to recovery "adb reboot bootloader" then you can wipe data/factory reset it.
Hi,
I'm struggling to get my Lenovo Tab 2 A8-50F into the recovery menu. I've found various sets of instructions that fairly consistently say to hold the volume up key and power, then let go when the Lenovo branding appears.
I've tried that a few times but it doesn't get any further; the branding remains on the screen forever (well, until I hold the power key long enough to reboot it).
I've also tried holding them a bit longer, but it just switches off, buzzes, and comes back to the Lenovo branding.
The volume down and power takes you to a menu in Chinese that's apparently a factory test menu.
I found someone else on a Lenovo forum who appeared to have the same issue, but there was no response to their question.
If anyone knows how to solve this or has any other suggestions, I'd really appreciate hearing from you.
Hope someone can help.
Thanks
John
Just in case someone else comes upon this thread, I never did get it to work using the normal hardware buttons. What I had to do was enabled USB debugging, install adb etc onto my PC, connect the tablet to the PC over USB, run: adb devices, then: adb reboot recovery. When I did this a little Android guy came up lying on his back and saying "No command". At that point, press power and volume-up and the recovery menu appears.
Hope this helps.
