My radio no longer starts after an unsuccessful root attempt. I've been trying to get into recovery for days now with no success. Maybe someone has a solution how I can get into the recovery of the radio so that I can install the original firmware.
The radio is a Pumpkin AA0717B, MTCHR_HT3_V3.81d_2 MCU, Rockchip RK3566
I would be grateful for any help

Thank you for your prompt reply. Have the cable (USB-A USB-A) connected to the PC. The device is still in a bootloop and is not recognized when switched on. Have tried to achieve something via RST button, unfortunately unsuccessful. Am I doing something wrong?
Edit:
Maybe the pictures of the board will help. Have these attached

If so, do you know which points I have to solder to so that the board is recognized on the PC? Since this board is very different from the PX3/5/6 board on your pictures. Here are some more pictures of my PX30 board.

It could be, that your cable / dock connector is dirty or faulty.
If your could test another cable (or buy one), this would be the first step I would do.
U're right, thanks!
I have another cable, tried that and it worked!
Thanks! Never crossed my mind to check with another cable since it's the original one.
One more thing html6405 please!
Which of rom's from your page would you recommend in terms of stability and higher vers of android?
Thanks again.

Hey autoid_os
I have the TC77 with identical Port. I want to make a USB cable for ADB/Fastboot Connection.
To you know what the Data pin's are in your Picture?
For this new Port I don't find any technical information.
Thanks in advance

But I think better is to buy cable for few usd

Yes, this is what I did for the USB cable.
I have another question, do you know how the serial cable works for the TC7x series?
I mean the part number CBL-TC7X-SERL1-01
It seems to connect to the same connector but the serial connector seems to be very big so I guess it is using some circuit like USB to serial for computer? I cannot find it anywhere to buy it that's why I am asking.
Can some one make me a charge cable and send to me.
I do not want to pay $100.0 of $30.0 for the cable the tc70.
Please help with how to unbrick MXQ-EP-2-V1.0.
Thanks

Want to bridge using paper clip
Hardbricked means a hardware component got defective, softbricked means either Android OS or device's bootloader got corrupted.

Ok thanks I understand now. So with device if I press the reset switch within the av port and connect USB cable nothing happens. Software doesn't detect any bootloader.
Hi, if still works, you must to short circuit the point that show you in the picture, the board go to maskrom mode. (the secuence must be, press an hold reset button, keep and hold the shortcircuit and connecto the usb male to male on to computer), i use RKdevtool for install RK322XMiniLoaderAll_V2.32.bin and reboot. Now is in LOADER mode, so you can flash a firmware normally. Any doubts just send it.

Thanks buds but the link to the driver is stale & not sure what its called do you have a name or a good link ? Oh and do you know where the maskrom short would be ?
TY
Also does anyone know where these pins go to on the board ? The traces are gone & shining a high powered light thru the board doesnt show anything that they were connected to..
