Hi,
I have hard bricked my RK3188 Pumpkin HU device.
I have try several actions (RST + power, print screen + alt +i with USB keyboard ) but the unit looks to be totally dead.
I only have a black screen and it is even not able to go in recovery mode.
I have got from some forum the possibility to make the processor boot up in MASK Mode by shorting pin 7-8 of NAND.
Unfortunately in my MB I cannot even see the NAND's PINs.
Any idea how I can force the MASK Mode in some other way?
See below the my MB

Use sd firmware tool of rockchip. Press update firmware, choose a work firmware and press create.
Disconnect rear power connector
Now you sd card into slot SD GPS in radio.
Connect rear power connector and you wait...the radio begin auto install update

HI all,
I have bought this model from Pumkin:
Model Number E0133
MCU Version R0HST16052800

CPU-Z tells me it's a RK3188 chipset, so we should be good.
I try dozen of times to access recovery mode using this method they mention on their website ( http://www.autopumpkin.com/forum/viewtopic.php?t=14 )
Just long press the power button without release, and while short press the RST button on the radio itself. You may hear 3 beep sound comes out from the HU. Then you can release the power button, the HU will automatically enter into the recovery mode.
But it doesn't work, I can't enter recovery and the only thing it does (from time to time when I change slightly the timing and order of buttons) is to automatically erase and restore the device, there is no recovery shown.
So how can I access the recovery mode?
Thanks!
You don't have an MTCB unit. Try the android head unit general section for help.

Hello, I have this tablet and I'm really annoyed because it keeps appearing the power menu totally random(it may vary some seconds), even if I don't press the power button or any button at all.
I've sent it to a service, they changed the power and volume buttons, but the problem still persisted.
Tried to factory reset it, no change... Tried to root it and flash a custom rom, no change.
I've also tried to disconnect the button from the tablet...No luck.
At least I know is a soft-related problem, not hard-related. Any suggestions what should I do or if there is any log where I can read what activate the power menu?

You could change the mapping of the hardware button to tell for sure if the buttons are the problem ...it could be the connector ....
Hi Everyone,
I'm reaching out because I'm desperate for help.

Here are the info I have on my head unit :

My A5 is stuck on dowmload mode and nothing I am doing seems to get me anywhere. When I press vol down and power it just reboots to download (do not turn off) screen. Pressing the power off button does not power off the phone. Pressing the vol down, power and home key reboots to download screen and I get attached screen. Tried odin but keep getting no pit error then if I add pit file I get 'cant repartition'. Also tried a few different stock firmware and three different cables a laptop and two desktop PC's ! Now at witt's end. Can anyone see if there is something wrong by looking at the image? Any help will be gratefully received.

Hi! I have a LG G7 and recently it started showing a recurrent notification for „Power supply - tap to change USB options”.
Also when I connect the charger it won't charge. I have to tap on the notification and choose charging mode to manually start the charging. When I remove the cable, in a few seconds, the power supply notification will appear again.
I changed the battery and the USB port with new ones, bought a new cable and it is the same problem.
Can I use ADB to enter system settings and force charging for indefinitely? I don't use MTP or other USB modes. Also tried in developer mode and after a few seconds power supply appears.
Thanks!
