Dear all,
I think I did something really REALLY stupid. I made one change in the BIOS settings which was to switch the RAM from Single channel to Dual channel. I then used the “Save and Exit” option to save the change and exit the BIOS. Now the device is completely dead… Simply won’t turn on. At the time I made the change, the battery was completely charged. Tried holding the Power-button etc but no luck. Someone has a idea?
Thank you for you assistance!
Best regards,
Ronald

August 14, 2017 at 7:51 am #70552Hi! Thx for the reply. Unfortunately the Tbook simply won’t turn on at all. It is therefore impossible to check settings or to revert back the initial setting of single channel RAM…
August 14, 2017 at 1:31 pm #70555I think you need to open your tablet and remove battery of bios for reset bios to default setting.
August 14, 2017 at 3:53 pm #70563Have you tried powering it on holding the ESC button and tapping it at the same time when booting? On the EZbook 2 and others, it would reset the bios to defaults.

January 7, 2019 at 4:56 pm #149852<h1>FIXED</h1>
Dear all,
Yesterday I was able to fix my tablet! My steps:
- Open device, very simple: just remove the mini torx-screws en use a flat object (I used a spatula) to gently loosen the back. It may take some force.
- Locate Eeprom. It is under the metal shield. Mine was a Gigadevice 25LQ64CVIG
- I purchased a cheap 4 USD USB programmer on AliExpress: CH341A Mini Programmer (Black Edition). Pay some attention to the jumper setting and correct drivers. I did a Youtube-search on the CH341A and this will provide you with all the necessary info en howTo’s. Programming Software was version 1.18.0.0. and did it on a Windows10 64bit OS
- I was unsuccessful using a standard EPROM Clip: tries two different models and both failed to stay attached to the chip. The best solution was using Micro TSOP clips. They are a bit more expensive but they worked 🙂 (example: HERE)
- I used the following BIOS: TbooK-16-Power-M5F8-Android6.0Win10-V3.14_20170209_BIOS_SKU
- NOTE: I was UNABLE to flash the EPROM UNTIL I desoldered the Batteries + (red wire) and – (black wire). This is very easy to do, no skills required just use a hot soldering iron.
- NOTE2: Although I was able to flash and verify the EPROM succesfully, the tablet refused to boot. I had to charge the device. Luckelly, I soon gave a low battery image on screen. Tablet was able to boot when charged above 30%.
Hope this helps!
Ronald
