I have a problem with the radio on android - MTCD Android Head Units General

Hello,
I have a problem with the radio on android. After trying to restore the data to factory settings, the android system does not want to get up.
It gets to halfway, shuts down and starts loading again.
Resetting with the "reset" button did not help.
I am looking for information on how to enter recovery mode, what keyboard shortcut. I tried different combinations but to no avail.
If anyone has android software to upload again, please send me. But I'm afraid that without revovery mode it will not be possible to install it.
Any advice/ideas welcome!
Successfully entered Recovery settings. Using a USB keyboard and " alt+Print+i "
However, it is not possible to switch between settings / up and down. The keys do not respond and the buttons on the radio also.

[Q] Root, unlock, etc without a working Power key?

My power key doesn't seem to work when I boot into bootloader. Works fine when in normal OS, but I can't even get to the bootloader with the normal Power + Vol- key method.
So far I tried to sidestep this "little problem" using hasoon2000's all-in-one toolkit, everything goes smoothly until I get to the point were you have to confirm you want to unlock,

The power key won't work and I can't move foward. Last time I tried I was stuck here for a while until the phone decided reset itself
I'd like to root and install a new rom on my phone, but how to get past this is completely outside my capabilities. Any help is welcome
Edit: I should add, sending it in for repairs is not a very viable option sadly, since I'm currently in Argentina

It's not rooted. Just upgraded to lollipop over OTA last week. Tried clearing cache from recovery, didn't gelp. Yet to factory reset. But want to know if there is anyway to do it by not factory resetting. Have some data in it.
Try booting into safe mode,to boot into safe mode turn on the phone and long press the power button and you should see "do you want to boot into safe mode" press OK.and uninstall any apps you may have installed recently.
use SP flash tools. download lollipop flash file. flash it, all will be ok

Nexus 7 (2013) Power Menu keep appearing all the time

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, I had this same problem. After resetting my OnePlus 5T during the 5.1.1 upgrade. Forgot my Gmail password so got locked out of the account itself.
You need to downgrade your phone to an 8.0.X oxygen OS stock ROM. There are plenty guides on how to do this through the button combination during startup to access the recovery.
Once the downgrade has finished, you'll still be presented with the Google FRP protection screen. When you're on the welcome page (where you can select the language and emergency dialer) click the emergency dialer. Once on the dialer you'll need to type *#812# which will open up location settings. Then simply click home and you're done.
I used this post way and it worked well.
Thanks for helping dude. i am so gladfull anyway )
