RK3066 flashed with bad mcu - Android Head-Units

Hello,
I have flashed my rk3066 7" (model s07) with a bad mcu, and he doesn't want to boot.
When i restarted device, i have a black screen only.... no access recovery (reset button power)
I need help for an issue...
Thank much.

You should still be able to get into recovery and reflash with a good MCU. Is recovery not working either?

This has been a lifesaver for me, as well as for many others: http://forum.xda-developers.com/showthread.php?t=2432476
It restores your phone completely to factory settings, allowing you to flash your recovery again, and start all over. Good luck!

HELP - My phone is bricked - cannot load recovery mode... ;(

Hello,
I loaded my SM-G900F with a custom rom and it suddenly died... There is no way to switch it on and when I connect it to my laptop it shows QHSUSB_BULK under device manager. I read a lot of posts and I understand that I need an unbrick image to boot from an sd card. Is that the right thing to do?
I would really appreciate is somebody could help.
Thanks in advance!

What rom, and what version were you on when you started? Which recovery, and which version do you have loaded? What, exactly was the procedure you followed, and what version of which custom rom did you try to flash?

Hi hexavoodoomal!
Thanks for replying to my message. The ROM was Sixperience 7.0. I am not sure about the recovery... I am sure I had TWRP installed.
Everything was working fine. The ROM installed properly and worked with no problems for a couple of days but suddenly the phone died. I am sure that it was updating something from Samsung. ANT+ may be?
Can you help?
Thanks!!

I hope so. Can you boot into recovery by removing the battery, and waiting for 10 secs, replacing the battery, and depressing the volume down button, the home button, and the power on button all at the same time?

No. I cannot boot in recovery mode. I tried several times...
Volume down is download mode
Volume up is recovery
A ROM can not break download mode, it's hard coded into the hardware, if removing the battery hasn't worked, power it on, and hold the power button for 30 seconds, remove the battery for 30 seconds, replace and try again
Oops, ha-ha. I called it recovery' didn't I? My bad. Get into download mode, follow the prompt, get odin, and flash the stock ROM for your phone. You can find links to the latest firmware on this site. There are other sites that have it too, but yiur best served geting it here. That will get you back where you started.

Its not working on me. I have the same device as ExL360, and the same problem. I tried many ways to enter the recovery, but they do not work. Maybe someone has already solved this problem, or what else can I try?

Suzuki Grand Vitara - M779 Head Unit PX5 Octa Core - stuck on Bootlogo

Hey guys,
I bought a Navigation System M779 (androidautoplayer.com) for Suzuki Grand Vitara from AliExpress one month ago.
At first, everything was fine and I was very happy about it. Nothing to conplain about.
Then I went on Holidays for about 14 days, in which the car wasn't used in any way.
Yesterday I started the car for the first time after Holiday, the battery still was fine but the radio did not boot. The screen stayed black and the Buttons did not light up.
After checking the Plugs on the back, the screen showed a Bootlogo, but got stuck.
I did not modify anything and everything was fine until Holiday.
Can you please help me?
Pressing reset did not change anything. Sometimes, selecting reverse does activate the rear cam. That's it.
I don't know how to enter Recovery or how to install the Firmware.
It is an Android 9 PX5 System. This is everything I know.
Kind regards
Robin
May be able to reflash firmware using this method - https://forum.xda-developers.com/showpost.php?p=79144579&postcount=2 assuming that the manufacturer posts firmwares on their site, or can provide it to you via download, email, etc.
Thank you for your reply.
I tried some Firmware-files, just to see If the head unit enters Recovery. This failed.
The manufacturer also replied to a Mail, telling me that they will hand me out a possible solution next week.
I will wait eagerly.
Hallo again,
unfortunately the manufacturer did not provide a solution to recovery my Head Unit.
I managed to get into the Recovery Menu and tried to wipe data, but this had no effect at all. Still stucking in bootloop.
The information given in Rcovery Mode are:
rockchip/rk3368/rk3368
9/PQ2A.190305.002/hct204281503
userdebug/test-keys
Recovery V9.0.5.
Supported API: 3
Can anyone please help me restore the Head Unit?
Kind regards

Did you try to disconnect the main connector from the unit and leave it that way for a few minutes ?
And then reconnect it again.
Thanks for your reply... But I think I did very stupid today and bricked the device.
Reagrding to this topic "forum.xda-developers.com/android-auto/android-head-units/head-units-rockchip-px5-mcu-csn2-t3912413" I flashed my device with "Fake Android 10 - July 6th 202007061156".
The flash ran smooth without any errors. But the screen seems dead now.
The buttonlights still turn on and do blink if I press the powerbutton for about 10s, but there is no bootlogo or anything at all.
I cannot enter recovery anymore.
**** happens?!?
Kind regards

Help: how can i enter recovery mode for this unbranded head unit ?

Hello guys. First of all, I've been searching for weeks for any similar situation with mine but couldn't find anything. I have Unbranded Chinese Android Head Unit running Android 4.2.2. with physical button and a reset pin. I tried tonnes of ways to get to the recovery with any possible method and nothing seems to be working.
can anyone show me how to get into recovery or force hard reset on the unit ?
I have attached a few pictures of the Unit info and the circuit board.
i tried to connect a USB keyboard to my Unit and pressed PrtScr + "E" but my unit did not show factory rest option. you can see what happened in the attached video
i will be thankful for you, if you tell me how to get into recovery mode of make a hard factory rest or install a new ROM.
Thanks in advance .
