MXQ PRO 4K recovery issue - Android TV General

Hello,I have a old tv box MXQ PRO 4K quick play.
By mistake i flashed with sd card method the firmware of Ugoos AM2.
Now device starts, but recovery button inside haedphone hole don't work anymore, so I can't connect to PC with AML flash tool, I can't install libreelec, etc
I only can go to recovery by android shutdown menu, but I can't install original fw because recovery says that the firmware is older than the one installed.
How can I solve? Can I install custum recovery from android or from recovery?
Thanks.

Thank for reply. The box has only recovery button in audio plug hole. At beginning the button let me start the box in recovery-upgrade mode. Since I flashed wrong firmware the button don't work anymore. I flashed original fw with sd card and flash pin short mode. The original fw now is on the box, but recovery button still don't works. So I can't install libreelec or armbian that is what i want to do.

Possibly bricked shield?

I installed the 3.0 update and it never removed TWRP, however TWRP is not working. If I flash the zip file for 3.0 it reboots the system in the middle of installing. I tried flashing the cm12 and cm13 zip files and they say they flashed successful but nothing appears to have installed, and I currently have no rom or firmware installed and can't seem to boot to fastboot. Any ideas?
Here is what happens when i flash the 3.0 zip file. https://youtu.be/-ZVnaNdn6-M
I seen the same logo don't know what to do as well. My parent click update while i was away from home when i got back it just the logo with nvidia.
Restore using the recovery images here for your device https://developer.nvidia.com/gameworksdownload using fastboot not twrp.
The way I get to bootloader is pull the power cable, plug back in and hold power immediately until the menu appears YOU MUST HAVE micro usb connected to a pc while doing this.
I'll give it a try. Thank you for the reply

Nvidia Shield 2015 16GB stucked on Nvidia Logo after flash 6.1 - how to solve

Hey guys.
After the time I spent trying to unbrick my softbricked shield 2015 16gb, I decided to share how I was able to solve it.
I was on 5.2 and decided to update to 6.1 since the developer image was released and my previous upgrade from 5.1 to 5.2 with flashfire run so smoothly so what could go wrong??
After install lastest flashfire 0.73, I select all but data on the flash firmware package, and let it run.
I had my shield on 5.2 rooted and with TWRP as recovery.
After flashing vendor.img it restart and get stucked on the nvidia logo, and there was where
my problems started.
After 30 min I switched off and on again and same thing. Nvidia logo and nothing more. 1 hour after that I finally was able to go into bootloader mode.
I needed to use the default USB cable that came with the shield connected to OTG and USB on my computer. As soon as I connect the power and the led goes on I pressed the power button until I was
able to see the menu.
From there I was able to run fastboot. I reinstall every build and the shield refused to back to life. Flashed successfully but wont go through nvidia logo.
I enter recovery and did a reset assuming I had some problem with my data. No luck. I start to assume my shield has a hardware problem.
I downloaded both the stock recovery and the developer image 6.1, 6.0, 5.2, 5.1.
Tried to flash all of them one by one. Nothing worked. It complete the flash process but after reboot keep stucked on the logo.
Lots of time reading XDA and googling it I found a TWRP 5.1 flashable zip image, and in last resort I download it, reflash TWRP and flashed the 5.1 zip image.
It worked!!
I run the wizard as a new shield, and return to TWRP and flashed SuperSu 2.79. Rebooted, and install flashfire and run again the process with the 6.1 developer image.
This time flashed ok, and I finally get 6.1 rooted and working perfectly.
So resuming all the steps for those who dont want to read all
If you are stuck on Nvidia logo after flash 6.1
1 - Download firmware 5.1 zip TWRP flashable (search on XDA)
2 - enter bootloader on your shield hardware mode. Connect the OTG port on Shield using the default USB cable, and after connecting the power and the green light turn on press the power button until the bootloader menu appears.
3 - Assuming you already had the shield drivers and ADB installed on your computer, go to TWRP recovery or install it. I flashed TWRP 3.02 (once again search for it on XDA). fastboot flash recovery "twrp filename.img"
4 - Boot to TWRP and upload the firmware with the command adb push "firmware filename.zip" /sdcard/
5 - Upload also the SuperSu 2.79 binaries. adb push "supersu filename" /sdcard/
5 - from TWRP install the firmware and let it run. It will generate some errors but it will work.
6 - Reboot and complete the wizard.
7 - Reboot to TWRP (you can activating developer mode, and run adb reboot recovery from inside the androidsytem) and flash the SuperSU
8 - Reboot again and install the latest flashfire.
9 - Download the 6.1 developer image (search XDA for it)
10- Run flashfire and install the firmware package. Thats it!
Hope this will help someone

Anyone pls help, Any comment helpful very appreciated.
Thank You for ur attention.
Remove and re-insert the battery. Then hold volume down + power button and see if the phone boots into download mode. If it does, then connect it to a pc with adb installed and see if adb detects it. If all goes right, you could try to install twrp recovey and afterwards install stock firmware through it. Google search A6000_S056_150924_WC51.zip and download the firmware and copy it to the external sd card then flash using twrp.
Although guessing by the state of your phone it seems unlikely that this will work. But give it a try. Hope it helps.
Thanks! It Worked

[help] adb doesn't see my shield

Hi guys I manage to brick my shield (2017 16gb on latest Oreo 7.2.3) I unlock the bootloader, flash twrp and lineage os as well gapps but the rom doesn't boot as it should it keep boot looping (I forgot to do the wipe but the system was clean anyway becouse I unlock the bootloader 5 minutes before..) I was not able to launch the recovery too. So I try to flash the twrp again... the result was bad. Now restarts to the nvidia logo and boots again. I'm able to put it in fastboot (Using A+B on the joystick plug and unplug and plug power cable) but the pc no longer see shield. Adb device's doesn't show it. Device manager says only Android device - Android Fastboot. Any Ideas how to make the pc to see it again. I have installed all the drivers and everything. Any option I give from the recovery ceep restarting the device endless.. I download the official nvidia shield recovery rom for my device but without seeing it in adb is worthless. Any Ideas ?

No recovery or download on SM-T500

Seems I found a way to semi brick my SM-T500. I was attempting to install the LOS 18.1 ROM just posted in the guide section. Some how I got the "can only install official" error message on my download screen after flashing TWRP. Made the mistake of flashing only the stock AP without BL or CSC and now I can't get into either recovery or download modes. Holding vol up and down and plugging in USB cable does nothing. Same with holding power button and either vol up or down. Blank screen. Can only power on and boot to system.
Did you install twrp and can you get into recovery. I had similar problem but was still able to get into download mode from power off. However to do so I had to boot into twrp and select reboot and power off... from that menu you can also boot directly to download mode... I know that doesnt halp much if you hadnt installed twrp yet... but thought I would throw that out there...

I can't boot TWRP or download. The only thing that will boot is system. Can't even get to the lock/unlock screen.
can you connect to adb shell? and try #reboot download
or #reboot twrp. I figure if you get to download you can reflash stock and start over.
Also when your trying to boot into recovery try not being plugged in. Not sure about this device but a lot of older Samsung's that I had would not let me get into recovery if I was plugged in during boot.
Locked oem mode
Locked download mode
Locked wipe factory
Locked update from sd card
Recycling item...
Need factory reset
I saw alot of issues with twrp so I tried Magick for first time ever on my SM-T500 and had a minor hiccup bc I wasn't paying attention to firmware and installed an old AP with newer firmware but ended up just reflashing the whole tablet with the same firmware as the AP that is required for Root and presto it worked! AND HEY IM DEF A NEWBIE!

Yeah I've run into the same thing, I originally missed the step to run Magisk after I flashed the patched tar and rebooted into the System and it triggered the "Prenormal KG state" problems. Finally I managed to flash stock ROM back and got to exactly where you are now.
I was able to just flash the patched Magisk AP without CSC and BL, and now it will only go to stock recovery and was able to get TWRP to work once but couldn't factory reset or wipe cache due to (which I assume was) a ton of mounting failures when it loaded.
Anyone else have suggestions to get this thing stable so I can flash LOS? I can get to Download mode.
hello, I post this because it's seems the same subject. I have to password protected (forget password) original rom tablet (non root). For me the datas are not important , I just want to remove the password or reflash with original rom. I downloaded Odin , usb driver and correct firmware. I select AP firmware with Odin, I see the connexion (COM3 green) and it's stuck to "setup connexion".
My problem is that it's impossible to enter in download mode.
When I try to shutdown the tablet, it ask me for a password.
When I press for seconds the power button , after few second I see the Samsung Logo and the tablet restarts.
I try to press volume up, volume up and volume down etc...but each combinaison...no recover, no download mode, nothing and impossible to flash . is it normal ? how to do to unsticked SetupConnetion ?
regards
bruno

This is not the same as my problem. My problem is that I flashed AP without BL and the two don't match. It isn't that things are locked but that I can't boot to anything but system. Can't boot recovery or download so I can't flash ANYTHING. Not even stock.
