For clone devices from China which are loaded with low-quality ROMs or even a wrong one.

That makes the Android TV project is unstable or even get bricked within the first-week usage.

So you need an intensive method to reflash the ROM via Maskrom mode.

Maskrom or DFU is the ultimate method to recover almost chipset, device brands or even phone/tablets.

“You should choose 6th-7th or 7th-8th pin from NAND bottom on the right side or 6th-7th or 7th-8th pin from first pin (first pin is marked on PCBA with a point or ) and circuit it during plugging to Host PC and powering on (check pin sequence for other devices very clearly)” – ugoos.

Furthermore, 8th and 9th pin are the default for not all of NAND/eMMC chip, so you must consult the manufacturer or technical forums.

The worst scenario is Windows does not recognize the Android box aka.

“nothing happened” that so many users complain.

Thankfully, a recent version of RKDevTool v2.

With proper firmware loaded, the Upgrading process will be finished about 10 minutes.

Remember that, a clone device from China have specialized ROM integrated with them, for example, I have a fake MXQ 4K, it does not mean I can install the original ROM for that device, even with the same chipset, Wifi, board ID.

These are so many factors to match for, eMMC versions, Bluetooth brands, etc.

So after try-and-fail with 15+ ROM file and 2+ weeks, I found the ROM for Leelbox KingBox is the only one that correct, phew!

You can use Remap Button, System UI Tweak to make it a truly dream Android TV like this one.

[ Download Boot Prepare IDB Wait For Maskrom Success ] Based on my experiences: you have to prepare excellent components before starting, otherwise, you never know why you can’t restore the freak firmware.

I build myself an old A-A USB cable that causes the tool to warns about bad memory chipset blah blah while the true problem is firmware file.

And you have to try the simplest/easy method first before detaching physical component of the Android Box that may cause permanent hardware issues: use Go Maskrom command instead of circuit memory pins.

“This is a common guide for reflashing RockChip based devices.

All RK SoC (RK3066, RK3188, RK3288, RK3229, RK3328, RK3399 and so on) supports the same applications and drivers for Host system, if 3rd party producers do not add any other limitations or special options.

Differences can be in hardware parts, so you need to detect OTG port and recovery buttons correctly” – ugoos.


ly/rockchip-flash It is recommended that you buy a branded device with good warranty and support policy so that you can have the device fix effortlessly.

A good example is this device have a true recovery mode with a convenient method to access it via this Recover hole, all you need is a toothpick.

Compare to my fake MXQ4K from China, the recovery does nothing more than an infinitive logo boot loop, what a shame!http://bit.

ly/best-android-box-TV “If the board powers on and finds a valid IDB (IDentity Block) in the eMMC, it will continue to load the bootloader from the eMMC and pass execution control to it.

If the bootloader checks that the Recovery button is pressed and USB connection is made, then it enters the so-called Rockusb Mode, waiting for further instructions from the host” – readthedocs.
