does anybody know what puts these magneti-marelli bricks into a bootloop??
or if they are android, how to get into the bootloader to do interesting things?

Hi,
I have a iMac A1418 board 820-00034, the problem is when the board is cold i can get to the mac os log in for like 1 min and then start the bootloop, but is a fast bootloop sometimes i can just see the apple logo for 1 sec and keeps doing it until i un plug the power, if i try to turn on again the bootloop continues, if i let the board un plug for 15 or 20 min i can turn on again and log in on Mac os but the bootloop start again under 1 min.
I try to get to the recovery and i can, when try to install a new mac os it starts loading the usb and then start the bootloop,...10-17-2024, 02:33 AM -
Hey everyone.
I have a Samsung QE50Q67TAUXXC (same as Q60T i think) which is experiencing constant bootloop. The picture comes on at first but then it begins to reboot again and again. I tried taping off the pins one by one on the ribbon-cable connecting the two panels at the bottom - and found that the bootloop stops when 1st pin from the left is taped off and the same if the 46th is taped off. (See picture). But unfortunately, I get no image on the screen in those cases.
The bootloop also stops when the whole right side is disconnected. Which makes me believe the problem... -
Hello,
I've ended up with a Samsung QE50Q60T with the classic bootloop problem. I've read plenty tape solutions on these forums but never seen one that made me progress to an image. Perhaps the model number makes a difference.
I've tried the usual disconnect LVDS and disconnect left/right methods and TV boots with no image on both. What amazed me though, if I tape the pin that sends 7V VCOM voltage then the TV starts up normal but due to missing VCOM voltage the image is whitewashed.
I've disconnected left/right VCOM from each other with another sticky tape... -
Dear community,
I came with this Sony set with a bootloop problem. Maybe you can help me out.
The Sony logo appers, the android OS starts to load, then freezes, then reboots.
So this TV set is stuck in a bootloop, the first thing comes to my mind is a faulty EMMC, but I couldn't find anyone with a programmed replacement IC or a working motherboard that doesn't cost a fortune.
I Only have a CH341A sadly, so I can't flash it.
I made some video of the original symptom, when you plug in the TV.
And I also made... -
Hi all,
I got an old Samsung 225MW TV with BN41-00825 motherboard.
Since the TV has a buzzer when it starts it makes a beep. The main problem is that the TV goes in a sort of bootloop and beeps every 2-3 seconds.
So I attached the VGA UART cable and read the debug data using a RT809H programmer:
According to the Service Manual all the voltages looks good, so I made a backup of the internal flash and all the EEPROMs (1 Settings + 3 EDID) and cleaned the EEPROM.
Now the TV boots but it's stuck on VGA. If I try to change the source it goes to TV, restarts...
