HeadUnit Broken, won´t start - MTCB Android Head Units Q&A

Hi, I have a massive problem with my unit. I tried to install a newer room on my KYD with 1024 * 600 RK 3066, but it didn´t work. I think it didn't even flash or anything, but now the radio wont start. The screen of the radio stays black and all the Button lights are on. The button lights stay on even if I take my car keys out and wont even turn off after some hours. I tried all known ways to enter recovery but there was no sound or screen shown and also i unplugged the radio but didn´t work. Is there a possibility to safe this unit?
Please help me & thank you
EDIT: My unit came with the cable attached. Could there be a possibilty to use it for ADB?

Anyone? Same thing happen to me too. I downloaded a update that wasn't meant for my device to extract and look inside for fun. I have 2 SD card and I accidentally flash the wrong one with that in it instead of Malaysk newest rom. My device is acting the same way as original poster. Any help, regarding how to get recovery back or even how to get into bootloader so I can flash recovery.img back into it.
I have the Joying Joying JY-UQ124, which is the RK3188 1024x600.

You guys cannot even get into recovery? If you can just wipe then install the correct FW over the one you installed. Did you modify MCU?

For me, nope. It'll turn on but black screen only. The element key lit up light blue and won't turn off even if car is turn off for hours. Tried to mimic the recovery after trying to put it into recovery. The screen is just black and stay there forever until you hold power and shut it off.

Did you manage to fix it? I have the same problem

What if you hold the reset button?

Nothing happens only some beep sounds.. I accidentally downloaded and installed the mtcd version instead of mtcb

[Q] Is my phone bricked?

Whenever I try to boot up my Desire Z, it would show me the HTC logo, but shut off promptly. I'd be able to enter the bootloader, but whenever I try entering recovery, I get this:

Is my phone bricked?
I'm not sure what was done previously, as I bought this phone second hand, so I'm wondering if there's anything I can do to rectify the problem.
Sounds like a soft brick, at the worst. You can fix it. Look up loading a rom from bootloader dezire z. Maybe you can put the new update on the sd card. You will lose root though, which you probably have if the got you stuck on that screen.

Try looking up about the triangle, also. There might be some buttons you can press etc.

At the triangle screen you show, hold down volume for a second or 2 then press and hold power. See if that doesn't take you to the text-based recovery screen (stock is blue text?).
PS - sounds like no rom and/or radio is flashed, that or someone tried to reroot and stockify it but bricked it as you describe. I'm inclined to believe it's been wiped clean. What's the bootloader show for your hboot, radio versions etc?
Ah, I was able to get it into the 3e recovery with the blue text, but unfortunately I can't do anything there.
I think I have another problem now, though. The battery won't charge. If I plug it in, it'll flash an orange and green LED, and from what I've been able to gather online, that means there's something wrong with the battery connection or overheating? It's not the latter, so I'm going to assume there's something wrong with the pins. The warranty sticker has been broken as well, so I think I think I'm SOL.
Thanks for the help anyway, guys!

Defy Buttons Problem

Hello everyone.
I have a really wierd problem with defy's buttons (menu, home, back, search). They stoped working at all.
So for a couple months I have been having strange problems with the buttons. It looked like home button was pushed and app drawer was opening/closing really fast. Reset has helped, but temporary.
And about a week ago the buttons stoped working at all. I tried to flash another ROM (official 2.2), but it didn't help.
And now I don't know what to do. I goggled it, but there is no information about such problem.
If somebody can give an advice, please let me know.
Thanks.
Nobody ? That's sad. XDA was my last hope) Well, I guess I will sell it for parts.
try doing an sbf. if that doesn't work, then there is hardware issue.
edit: dont know if you already did..since you said you flashed an official 2.2 rom..
Don't know if this will work but it won't hurt to try

Download the files and android commander search it up. It's easier than manually using adb commands.
Connect your phone to pc and make sure usb debugging is on
In android commander navigate to system/usr/layout
Then click on push on the toolbar in android commander
Select the files you downloaded then right click on each file that you just added then click on properties
make sure each one looks like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

Maybe this will fix your buttons?
from http://android.site666.info/indextricks.htm :
home key, search button, security lock, power button options: repair them
Some phones do strange things at random: your home and search buttons stop working, your security lock won't load (leaving your data wide open), and if you hit the power button then reboot is your only option, because silent mode and flight mode are missing from the list.
There's nothing wrong with the buttons on your phone, but there's something wrong with the software that controls them.
• Fix: backup your apps and data, reset your phone to factory settings, restore your backups.
Make sure you have a full backup or two and check that the backups work before resetting your phone.

Xperia Play Defibrilation :)

Hey guys, this is gonna be kind of a long story but bear with me please.
I got an Xperia Play for dirt cheap today. The guy said it just vibrates when power button is pressed and doesn't boot but the green/blue led comes on so I guessed it was bricked or somethig. Oh, and it also doesn't have the battery cover.
So i tried flashing R800i_4.0.2.A.0.62_(1253-4437).ftf and Xperia_Play_2.3.3_UK_Generic.ftf via flashtool and "update" via update service but to no avail. Same symptoms.
I thought the screen is totaly dead and inserted a SIM card, pressed power, waited a few minutes then called that sim but the SIM was unavailable so I guess phone really doesn't turn on so a software fault is still an option.
Any ideas guys?
Also I wanted to ask something, what is this little white thing in the picture? Could it have something with the phone not turning on without the battery cover, I know my old HTC Startrek had something like that.

AFAIK that's the lever that disables the SD card while the phone is on so it can be removed without corrupting anything
And i'm pretty sure my PLAY turns on without it's battery cover (i remember doing it some time ago when my SIM card was going PMS)
I just had this problem today as well when I pulled my old PLAY out to use it for an alarm clock.
Download flash tool 0.68, install the drivers, and download the stock 2.3.3 ftf file.
hold the back button and plug the phone into your computer. drop the ftf file from the zip archive into flash tool and follow the onscreen instructions.
when its done, pull the battery put it back in an boot the phone. It will take 5-10 mins for the first boot. Make sure that it is done BEFORE you pull the battery though... pull it before and u really WILL brick the phone.
The problem is that the screen shows no signs of life at all. Was that the case with yours too?

One more thing. I jsut noticed that I don't need to hold back to connect it in flash mode, just plug the usb cable. Could it be that somehow it's stuck in flash mode?
Maybe "back" button is stucked. Try to open it and clean it

any other ideas guys?

[Q] AFTV hangs at white logo. Did I just bricked it?

Hey guys,
I was just doing the process to flash the pre rooted update, I used the AFTV Utility.
The steps:
1 - Unlocked bootlader OK
2 - Changed the bootloader OK
3 - Change recovery PROBLEM
After I changed the recovery, it restarted and now hangs at white logo in startup. Tried the print screen/sys but nothing happened, the funny thing it's that it seems not to be powering USB connection since the keyboard just doesn't even light up or any of the leds when connected (like the num lock led).
Thanks in advance for any help.
The same thing happened to me with I used the AFTV utility,
Yeah I think it's bricked. I returned it for a replacement then manually rooted/unlocked/rboxed following the AFTVnews guide and and it all worked.

Snap to the above.
Tried following the method outlined here: http://forum.xda-developers.com/showthread.php?t=2799779
However I'm not getting any power via the USB at all so can't use a keyboard.
Any ideas?
Can you guys who've bricked plug a USB device in and have it powered?
Cheers

Unable to boot error but still have access to twrp and rom

Hello,
I've been at war with my phone trying to figure out hot to fix this bootloader problem but no good answers. If I turn on my phone I get the wait 5 seconds message and if I hit the power/lock button before waiting I get this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
If I leave it alone and don't hit the power/lock button it will boot normally to my rom. I also have access to twrp. Any help to fixing this is greatly appreciated
I am on Dirty unicorn 11.6
Jaguar rom also come buggy for my phone some reason? And briefly can some tell me why my phone doesn't charge while it off? It turns on as soon as I put in the charger?
Update: I got bored so I flashed my ROM again and it went away. But as soon as I rebooted and flashed gapps it broke it again. But I'm still able to access the ROM. It also breaks when installing magisk. I'm guessing it breaks the boot image
Solved: I flashed a stock rom using qilf. It fixed the problem but twrp got removed and bootloader remained UNLOCKED so i just flash twrp via adb fastboot and got my root back
yes i got the same problem im waiting for any solution
