Device: 43LF621U19 Problem: stuck on searching for your remote screen. - Fire TV Q&A, Help & Troubleshooting

Okey, the problem is divided in two parts.
The first one, today I notice that the Tv lost network connection over WIFI, when I enter to the networking setting I notice that there where no networks to select at all and that the only option it gives was to restart, and so I did, after the restart it was the same, no network, and when I enter the network setting no WIFI to select, I power of the TV, waited a bit and turned on. Same thing happend. So I decided to factory reset. After the factory reset, the tv restarted and language screen appears I selected with my control and then a screen saying searching for your remote appears and I'm stuck there!.

I already tried restarting the fire tv remote presing left cirble butten + back button and hamburger button, then change the batteries for new ones and after the new batteries where in tried the home button, but still cant pass that screen. I also tried a ethernet cable to the tv and the fire tv app on my phone. (the phone recognize the tv) but it didn't pass that screen also.
If anyone has this issue or have any Idea what to do I would really apreciate it.

Try response 2 or 3 to another user with the same problem:

Also try holding the home button on the remote for 10sec to put remote in pairing mode

My Dumb Ass told my Wife's Parents I could fix their tablet (Stuck in Reboot Loop).

Good Morning!
I have lurked hear on and off when I had problems before with my Samsung phones so I thought I was qualified to help my Wife's parents with their Galaxy Tab 3 10.1. They aren't techy and will buy something new at the first sign of trouble. I was just hoping to save them a couple hundred bucks. All they told me was that it wouldn't turn on. I'm not a techy guy myself but I know how to google and follow instructions so I'm the de facto IT guy in the family.
What it appears is happening is that it's stuck in a sort of reboot loop. I read a bunch of threads about starting in recovery mode and hard resets or hooking it to the computer and updating it from there but nothing works. The computer won't recognize it when I plug it in since it's constantly rebooting. None of the button combos (power+volume up+home, etc.) work either.
I made a quick YouTube video of the problem but as a new member I can't post it but it just flashes the "Samsung Galaxy Tab 3" on and off until I suppose the battery dies.
Any ideas on what else I could try?
If this battery connector is severely cracked, your tablet won't be able to boot.

You can try this, press hard on the back cover near the center to see if it can boot or remove the rear cover and press directly on the battery connector while power on.
Power + Volume Down ( next to Power Button ) is Download Mode
Power + Volume Up is Recovery Mode.
If you cannot access these two modes, may be your power or volume buttons are not working, I guess. The flex cable for these 3 buttons only few dollars on Ebay.

Using FireTVstk4k for presentations Bypass Home Not Available-Network Lost

Back on my original firestick I could use it without having a network connection. I used this for presentations in remote locations. Much easier than carrying and setting up a PC.
That firestick got damaged in a fire and I replaced it with a firetv stick 4k model. Even if I hold the home button>apps and start up Kodi, it will kick me back to the firetv launcher with these home not available/network connection lost messages. Also performance seems to be really bad without a network connection as when showing some videos it would stutter without internet vs playing just fine when connecting to wifi that has internet.
My question is can I somehow bypass or disable that requirement to be connected to the network and also the internet, either through disabling some app or changing a setting through ADB?
I see now that the 4k can be unlocked/rooted/etc I would have no problem doing that if required to get back to being able to do my presentations with my firestick.
Thanks in advance!
I was hoping to use a 4K Firestick to play movies and TV shows off a USB stick (via an OTG cable) while travelling. Your question also applies to me as I won't have internet everywhere and shouldn't need it for local playback.
That would be awesome if I could use a USB memory stick as well. Would make it that much more versatile.
I can often tether to my cell phone, and that works. But sometimes I don't have cell phone service nor local wifi networks where I am.
If I could just get past these error messages.

AE0273B Android 8 unit 'Can't load Android System' error?

Hi, I have a AE0273B.02A unit running Android 8. It's been working great until today when I suddenly crashed then displayed a 'Can't load Android system' error. See attached photo.
The messages mentions using the buttons to try a factory reset, however, all the buttons are non-operational, I've tried long and short pressing
Is it possible to re-flash an Android ROM to fix the unit?

This is the software version the unit was running before crashing, can this be reloaded:
What have you tried - using reset button to scroll thru menu?
Tried USB keyboard?

Click to expand...
Click to collapse
I've tried long and short presses on all the buttons, all buttons are totally non-responsive apart from the reset button which immediately reboots the unit.
Interesting idea to try a USB keyboard, unfortunately this didn't work either.
I'm not sure what to do now, I've managed to find the correct image for my headunit. However, without being able ot access the recovery I don't think I can load it. Any idea or is the hardware toast?
Issue has been fixed! I found if I connected the USB keyboard to the 2nd USB port it detected the keyboard after a reset, and I was able to choose "Try again' then the system reloaded successfully. Thanks for your help

Samsung Galaxy tab S4 - VZW Bootloop / Splash Screen

Boot Looping Samsung Galaxy Tab S4 scenario​1- If you cannot access your device, download the ADB and latest version of Odin
2- Hold Volume Down + Power and HOLD (I'm talking even after booting, I believe this clears the cache and re-initializes
device lock
3. Repeat. . . .
Many people give up or move on to something else at this point to try to fix, if it's still not working
squeeze the front and back panels together (softly) to ensure no loose Display cable,
then... hold
VOL+ VOL- + PWR This resets the device as if you were pulling a physical battery out, clearing the cache, repairing security program. REPEAT until Tablet says cannot initiate Encryption service, and will repair itself. IT WILL REBOOT
No need to hold the buttons this time as you will see your login screen.
The Secret is VOLUME UP - VOLUME DOWN + POWER for 45-50 second intervals.
Took me a day and a half so I figured I would save you some trouble.

+Yes it is still possible that this does not repair your tablet, I do not suggest taking off the back chassis as I have seen professionals break and hard brick devices this way.
IF YOU DO - Use guitar picks and or the official phone repairkit tool. YOU WILL need it.

[Firmware request] TCL 55C815 MAC adress unavailable, stuck after OTA update via USB

Hi everyone,
I've got a 55C815 TV, and I've been controling updates manually since 2021 and before updates i come here to see if there is any complaint.
Lately a did the mistake of activating automatic update, and the problems began.
The ethernet network card MAC adress (which is used by some application to authenticate) was not available on the TV, so it was invisible to application.
When I activate WIFI, a MAC adress apears but it's the WIFI card MAC, so useless for me.
However, ethernet network card MAC adress was visible on my router monitoring. So the problem comes from the OS I think.

Did someone had the same issue ?
After that, I went to TCL site and used "V8-R851T02-LF1V645.018859.zip" OTA update file (wich is a downgrade in my case I think)
So now my TV is stuck in a loop:
TCL logo -> Android logo -> black screen -
^--------------- Restart --------------------|
[Request]
Do someone have V8-R851T02-LF1V645 or V8-R851T02-LF1V625 IMG updates please ?
I did a search here and the links are dead.
http://celesw.tcl.com is no more accessible.
I wanna try V645 to see if it boots, and check ethernet MAC adress,
And if necessary doowngrade to V625.
Thanks !
