The first time I had the firmware MTCD_KGL_V2.54_2 and update to MTCE_HA_V3.45_1, but when I was using it it always emitted a beep, as if I was pressing something, so I thought I had installed something wrong, I tried to return my installation to zero, dupdate_5_1_1_FUSE_MicroG_1024X600_800X480_RK3188_13_MAL_08_07_2018_MTCD, but I blocked buttons and could not move to anything, but at the moment it stays in the lollipop image and when I insert the sd, it restarts, try to put the last one
I need your help please

How Do I enter into recovery menu?
Depending on the HeadUnit, the entering into recovery process could vary.
Reset Button Procedure (You need a needle to access that button inside the Reset hole)
Applicable to:
HeadUnits with no physical buttons on Headunit (just capacitive buttons) [Brands: Dasaita]
1. Press Reset and hold until button light blinks (15-20secs)
2. Release Reset and press again. Hold it until you see the Marshmallow logo
3. Release Reset and wait for the Recovery menu to appear
Power Button Procedure [Brands: Dasaita]
Applicable to:
HeadUnits with physical power button on Headunit [Brands: Dasaita]
When none of the above procedures worked:
1. Disconnected all power from the unit... ACC & BAT disconnected
2. Prepared 12V power supply with on negative and two positive connectors
3. Connected negative to GND & one positive to BAT
4. Connected USB keyboard
5. Press right ALT (ALT GR on some keyboards) and PrintScreen
6. Connected the other positive lead to ACC (unit does not work if both BAT and ACC are not connected)
6a. Start pressing repeatedly on E (not holding E pressed, but press...release... press... release..... rapidly)
7. The boot logo shows (MarshMallow...etc) and after a few seconds the unit reboots itself
8. Release right CTRL & PrintScreen and continue to repeatedly press on E.
9. The Recovery shows on screen.
4. I have a complete Bricked Unit with a continuous loop. What can I do?
First of all, you have to try to reload the firmware into the unit. As you are not loaded into Android system, you must reload the firmware by using the recovery menu. To enter into recovery menu read the FAQ#3.
Most of the times, reloading the Android firmware solve the issue.
