HOT! Download Android KitKat 4.4.2 stock firmware for new E-ceros Revolution tablet



Download Android KitKat 4.4.2 stock firmware for new E-ceros Revolution tablet from here, here or here. Firmware image file name: q9_ct9716_4.4.2_20140428.img. From here you can download Android Jelly Bean 4.2.2 stock firmware for first generation of E-ceros Revolution Tablet.

Beware! Flashing your tablet might avoid your warranty, so the risk is yours. Some users reported a soft brick after upgrading process on first / old generation of Revolution tablet.

Some advices about soft unbrick
- this is if you flash by mistake with a different / incorrect firmware or bootloader on RK3188 devices.
- if you flash the wrong firmware or the wrong bootloader you can end on Windows 8 / 8.1 with the famous error 'Unknown USB Device' (device descriptor request failed), currently still largely met at ROCKUSB devices with micro USB connector. To fix that you have to temporarily use a PC with Windows 7 or Windows XP just to flash back the correct firmware (in this case maybe you'll try Jelly Bean from the link above).
- if the deviced is not detected at all, connect the power cord to the tablet, then connect it to the PC via USB cable. If this is only a soft brick, in some cases, the device should be soon recognized by the PC, then flash back a good firmware from the list above.
- Bad flashing leading to soft brick which could be fixed by using RKBatchTool in conjunction with using a hardware button combination (power and volume down) to fix USB recognition errors and then flash as normal. 
- sometimes bad flashing leading to corrupt NAND which caused a "043 error" which could be fixed by physically shorting the NAND module, using RKAndroidTool to erase/wipe the existing NAND, and then reflash with the RKBatchTool as normal. Not recommended at all for unexperienced users. Best advice: send the device in service for repair.

Excellent !!!!! Dear Dan Stefan THANK YOU VERY MUCH for the article and the file links. I have a e-ceros Revolution with Kitkat 4.4. "checking" the tablet I accidentally enabled "Simulate secondary displays" and the system restarted with a loop trying to reset the screen. I tried to reset the tablet through the pinhole reset button but was unsuccessful. Only these links allowed me to restore the configuration and "software unbrick" the tablet. Greetings from Mexico and best regards.
