Hi everyone!
I have an Onda V701s tablet that runs on the Allwinner A31s SOC. Specifications of this tablet can be found here: https://www.imei.info/phonedatabase/onda-v701s/
While trying to root the tablet with ADB commands, I bricked the device. When powering on the device, it is stuck on the Onda boot logo. This boot logo shows the brand logo with the text "SINCE 1989" underneath it. The device does not boot any further, no matter how long I wait.
I've tried to connect the tablet to my Windows 11 (64-bit) laptop in a special download mode using the following steps:
Power off the tablet
Press and hold volume button
Connect USB cable from the tablet to the laptop
Press the power button up to 10 times until the tablet is recognized by the laptop
These steps indeed result in a different connection between my laptop and the tablet, but I am still unable to flash the stock firmware. To do this, I've tried LiveSuit and PhoenixSuit, but both pieces of software do not recognize the tablet (no device connected).
Does anyone here have experience with flashing bricked Allwinner chipset devices?
If more information is needed to solve this issue, please let me know

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.

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!
Have you tried the Tech Know forums : http://www.techknow.me/forum/index.php?board=130.0 ? They are quite resourceful when it comes to cheap tablets or devices.
Some wanker had posted wrong images for boot and recovery for S6000L. And since I'm a moron, i didn't take the files apart to check them.
Installing them bricked my tablet. So essentially I have no boot or recovery images on the device and was wondering if there's any way to revive it.
Tablet freezes if i start it in normal, fastboot or recovery modes, so that's out of the picture.
However, i think that "meta mode" still works (if indication of it working is displaying lenovo logo and having "meta mode" written on the bottom of the screen)
It's getting detected on "mediatek preloader usb vcom port" for a couple of seconds when connected to the PC, which means that i might be able to use adb to push a backup into the tablet (?)
Been scouring the internet for a while with no results. Is there, by any chance, anyone who can help me out?
Hello everyone,
Recently I tried to flash my Freer X9 Tablet (aka U89) with Android 7. In the beginning the SP flash tool was not able to detect the tablet, maybe because of a driver clash. Then the flash process started very very slow and stopped in the middle for some unknown reason. I had to exit the SP flash tool.
After that, the tablet seems to be hard bricked. It does not start, it does not respond at all. On the other hand, when I connect it to my laptop, the laptop is able to detect it as Mediatek USB VCOM device.
I came across some threads which mention Meta mode which can make the device start working again but for it to work, I must physically open the device to disconnect the battery since the battery in this device is not removable. I do not really want to do that fearing that the tablet could be damaged while I open it (locks, paint and stuff).
Can it be unbricked in any way without physically opening it? Any help is highly appreciated.
Thank you in advance.
Solved!
Well, I waited for a day and guess what, the battery got discharged. I don't know how. I put the SP tool to download mode (clicked the download button). Connected the tablet to the laptop while keeping the volume up key pressed. I did not release the volume key for 10 seconds even after connecting it to the laptop.
And... boom! it started to flash!!! the tablet works now!
