Thanks for this! My Sharp Aquos 55LE653U was stuck in an endless reboot cycle. It was not getting far enough into the boot cycle to recognize the set of button presses to bring up the factory service mode. After inserting the flash drive with the firmware file, the instructions from Sharp said just to restore power by plugging back in and wait for the white front power light to begin blinking, indicating a firmware update in-progress. There was nothing displayed on the TV during the update. The update took 3 minutes, after which the TV rebooted and came up in the initial setup menu. Fixed!

Sharp requires one additional step with my model: With TV powered on, use remote to enter "MENU-2489". This brings up the service menu. Navigate to Setup/Clean Storage and select "YES". I believe this clears out the EEPROM settings. Power off and on to restore normal operation

Sharp lc-60le644u by the way is my TV model

I know this is an old video but I hope I can still get an answer. I followed all of your instructions and when I was ready to do the update on the TV,  I got an error message saying that the file is not detected in the USB memory device. I tried formatting the USB several times and it still didn't fix it. My problem is that I get a black screen when trying to access Netflix by the way. Software I downloaded is the same one on the TV.

I have a vizio M3d421 SR tv that won't turn on. I have a suspicion that it may be a firmware update issue but I cannot find the firmware file anywhere to download. Can you help me know how to fix this issue?

I having a repeating reboot problem on my sharp lc55le65653u tv. Would a firmware update even fix this?

I accidentally updated my Aquos TV with the wrong firmware, I can still access the menus but they are confined to a smaller area of the TV than they previously were, but I can't find the stock firmware for my TV in order to restore it! If you can help it would be much appreciated, I need the firmware for MODEL: LC-32CHE4042E / SERIAL: A32CH4042EB13V . Thank you!
