Hello, I tried to install a custom MCU with sound patch and now the unit hardly boots. I got it to boot but it shutted off and I wasn’t able to flash the original MCU. I’ve been trying to get into recovery by holding down the power button until the key backlight flashes three times still holding it for three seconds and then letting go and pressing again.I tried with ADB but still no success.It is a PX30 MTCE LM.
I am sorry I posted this in the wrong place.

Hello everyone! So I've had my phone (HTC One M8) rooted and custom recovery and rom installed for a little while now. The latest rom I've installed was Android Revolution HD 22.1. I also have twrp 2.8.1.0 installed. The other day my phone got wet and started to constantly reboot itself, wouldn't shut off and stay off, would never actually start. I put it in a cup of rice for 2 days, then proceeded to plug it in to charge it. Once charged enough I tried to turn it on. It only made it the HTC One logo screen and would vibrate every 10 seconds or so. I tried rebooting several times and no matter what I did with different button combinations I could not get it to load into bootloader. Eventually with restarting different ways and "mechanically stressing" the phone (short temper lol) I managed to get it to loading into the rom itself. From there I opened hasoons all in one toolkit to reboot directly into recovery and recovered to the stock rom. So the phone will now reboot with no problem into this rom. I haven't tried reflashing the ARHD 22.1 rom again because im afraid it'll break again. However, while in the stock rom everything work fines except for the volume up button which does nothing, except for while the screen is off, if I turn my phone to landscape the camera app will open without me even pressing the volume up button. If I reboot into bootloader via the quickboot app or hasoons toolkit, my volume down button with make the cursor go up, the volume up button does nothing, and the power button does nothing. The only thing I can do in bootloader is to hold power+volume up to get the phone to reboot. I also cannot get bootloader to load by holding volume down+power. So, After all that explaining, my main question would be, do you think that the buttons are shorting in a weird way because of water damage, or do you think my software got corrupted because of all the rebooting it did? Any help is appreciated, thanks!

UPDATE: my power button will now lock my phone but not unlock it.
Hi
Could some one tell me why i cant get in recovery or factory mode with hardware buttons, i am on stock 10d with twrp recovery installed and rooted wirh super su through twrp. I installed twrp through adb with normal command and device works just fine through reboot apps from os, boots in recovery,fastboot etc just fine,same through adb commands.
But there's no hardware combo or anyrhing working when trying to enter recovery or factory reset working at all?
Tryied every combo i could find saying how to from internet.
It just boot up in os as usual.
And phone dosen't reset while holding power button for 10s + either
It's a bit scary because bootloop is going to come eventually for sure and then there's no rescuing avalible
Could someone plz tell me whats going on?
Im new to g4 so, some help would be nice.
Thanks in advace
It's a bit tricky, to be honest.
• Power off your phone
• Hold "Volume-Down" and keep your "Power-Button" pressed. So you should keep both pressed, until the 1st LG logo appears
• Now just leave the "Power-Button" for ~1 second whilst kept the "Volume-Down" button still pressed, press now the "Power-Button" again and keep holding it
You're now forced to deal with the standard-ui from LG. Go to "Yes" and again "Yes". TWRP now boots and you should be fine .
Edit: Just my tiny story... I watched several videos and also had a nasty bootloop. I was afraid, I now bricked my phone. But a nice user showed me this way and this was the only way, I got my phone recovered.
i recently updated the mcu to kld2 2.81. Now i can not get in to my recovery manual to fix my rom problem. i can only get into from the rom power options. everything i hold the power buttons it gives me 3 shorts beeps like normal. then one long beep then nothing happens. no recovery anything. i have tried holding reset button all i get is a long beep. Someone please help me?
Hello everyone,
I have an 1-DIN RK3188 KLD MTCB unit. I was using a Malaysk firmware for some time now with no problems except some random reboots now and then. Yesterday, after changing a setting for reverse camera (mirror - off), the unit just died. It is not powering on unless I use reset + volume know combination. The screen does not come out, nothing. When short press the reset key, the buttons blink once. When using the reset + volume knob combination, the unit powers on to recovery and stays on no matter if acc on or off (before, when acc where off, the unit shuts down). Tried to reflash with original firmware with no success. Any ideea what could have happen and what can I do?
LE: I managed to make the screen come out (must press the open button right after power on). Tried installing factory firmware but when reaches reboot it is shutting down. Could it be the MCU?
Thank you!
UPDATE: After some tries to reinstall the firmware (both Malaysk ROM anf factory ROM), I also updated the MCU. Unfortunately, no change. Then, I started to look for the problem elsewhere. I discovered one faulty fuse, exactly the one responsible for ACC 12V at the unit. After I installed a new fuse, the unit successfully booted but now I can no more control the flip-up screen. I flashed the MTCB-KLD-V2.78 MCU. Is this MCU universal (both 1din and 2din) or do I need a specific one?
Hello, unfortunately I also have the problem with the recovery mode. I can not find any way in this. I have already tried the power button for 10 seconds. Then the lights of the radio flash several times but it does not happen. Even if I briefly press the power button again briefly (even several times) nothing happens.
Does anyone know advice?
