Rooted my kindle fire first gen and installed cyanogenmod 10.2. Everything works fine, except for the fact that i cant reboot. Everytime i attempt to reboot i end up in boot loop. The only way i can get it turned on is if i plug it in to my laptop and use this method, Unplug the Kindle Fire from the USB charger cable, press and hold the power button (it should not turn on because the battery has run dry), while still holding the power button, plug the USB charger cable in (it should not turn on yet), wait for at least 40 seconds while still holding the power button, and once the kindle powers on, immediately let go of the power button and pray. Anyways, I was wondering if anyone had a fix for this problem. Thanks.
Hi! I am trying to enter the download mode of my TCL L32S6500 TV to install an update.img with root included, but none of the ways I found worked for me.
I already tried:
Pressing the power button for 10 seconds when starting the TV
Pressing the power button until the lights blink (they never blinked)
repeat the two previous methods unplugging and plugging in the tv again.
I also tried with the USB plugged in and I still can't enter
What else can I do? I'm already running out of ideas
Edit: I just finished trying to enter the recovery, download, and fastboot mode from ADB, but none worked, it restarted normally

Have you found how to enter the DL mode? I was wondering the same.
Hello,
I have a tv TCL 55DP660, motherboard is MT58CU (40-mt58cu-mab4hg).
I am stuck at loading screen and nothing works for me, after I entered developer options and turned on Debug mouse setting, my tv restarted and was in forever looping state.
What I tried
1) turning the power off
2) inserting usb stick with file in root (V8-T658T01-LF1R579.pkg) tried with multiple version, all produced same result, as well with .zip extension
3) Holding down power button on tv
4) Plugging into electricity
5) screen shows TCL logo static
6) after 10 seconds, it show "TCL" logo animated
7) and then it showns loading and gets stuck there forever.
Also tried opening my tv, and taking a loot at motherboard, but could find a reset jumper, or reset pin to short circuit.
The only thing I found was MCU_RST name on a back of the board, but it was only a single filled hole and nothing around it. So was wondering to which connection do I short circuit it so it would do a factory reset for me? or is there another way?
Thank you!
Try V574 pkg file....unzip to "Update.pkg"

Just tried it.
Formated usb with fat32, and put inside root "Update.pkg" file.
Unplugged tv -> inserted usb (tried twice with both slots) ->started holding power button -> plugged tv -> tv started loading showing static TCL logo -> after 10 seconds it booted as if normal and was stuck on loading screen forever.
Maybe change USB ?

hi, 1 question...
have you the instant on issue?
Hi,
i tried this solution, but right now the only thing i have is the stand by light on. it doesnt do nothing.
i already tried light on the the with the remote control and nothing.
somebody help?
there is any other solution to flash de mainboard?
thanks
I knew I shouldnt of done it. Its just my luck.
Tonight I installed the R112.....V8-R851T02-LF1R112 CFW posted a few days back.
Previous to this I had V8-R851T02-LF1V453.018444 (stock)
Install went fine. Booted up, I went through set up. I enabled developer options and enabled adb. My phone could not find the tv to sideload anything so I restarted the TV. Powered down, then back on. But flickering every few seconds along with the white light on the bottom.
The bottom doesn't work for anything. I found if I unplug it and plug it back in then immediately hold down the button the light will start flashing like its installing a firmware. I tried to reinstall the one I previously mentioned. It blinked for a bit but then back to the same flickering on and off.
No help expected, anything GREATLY appreciated.
I tried to include as much info as I could.
Thanks
First, R112 is not for your TV.
If you can enter TV setting , reflash firmware by "Local update" with V458 OTA file ,posted here:

or try reflash by TV power button.
No IMG file released for S343.
Hello Stasiof, Thanks for replying.
I fell asleep last night waiting for the file to transfer to USB.
This morning before work, I unzipped all files onto the root of a FAT32 USB stick, put it in, started the TV holding down the button. It flashed like it was updating, but very briefly. I would say about 15 seconds. And nothing afterward. A blank screen still. Was I not supposed to unzip?

Do not unzip, copy to USB as downloaded.
2 days ago I came back to my Fire TV Stick 4k only to find black screen with "loading..." letters in corner, and at that moment pressing home button did nothing, seemed that remote isn't working at first or device froze.
3 Hours before that I has using device, and only thing I did i power toggled it 3 times in few seconds using power button on remote (don't ask why it irrelevant now)
After I power toggled the device, and after "Fire TV" logo it stated that it can't find my remote. So i changed fresh batteries, tried to resync remote to device and all other stuff, but nothing helped. So I decided to try my remote on another device, and concluded that remote is perfectly fine and connects to other device without problems, and that it's nothing wrong with it.
At the same time it baffled me that device didn't load home screen after boot, just notification that it cant find remote and black screen after that.
Later I discovered that remote is in fact working (built in firmware restore functions and menu that is accessed by long pressing home button for few seconds).
So I decided to do factory reset by pressing key combination.
Factory reset menu came up, and after I pressed "OK" nothing happened, device didn't reboot.
Pressed key combo again, and let the timer for factory reset count down to zero.
When it came to '1' it froze.
Pressing key combo again factory reset menu would come again and do countdown from start.
I can also invoke menu accessed by pressing home button for few seconds, but what ever I choose from there it freezes, but if I press home button again it opens same menu again and move left-right and even enter "profiles", so it's not frozen, it just seems that it can't open any menu entry for some reason.
At he same time I can access it via wifi ADB and run ADB shell commands, so it is connected to wifi that has internet access.
I tried running "adb reboot recovery", device reboots, comes up with Fire tv logo and "no command" on screen.
It sits there for a minute and after it reboots and goes into normal boot.
I also tried "am start -n com.amazon.tv.launcher/.ui.SettingsActivity" folowing "am broadcast -a com.amazon.tv.intent.action.MASTER_CLEAR" but no avail.
it states "Broadcast completed: result=0" and that is it.
How do I factory restore / flash firmware, whatever ?
I will take any suggestion before tossing it into bin, because I think memory got corrupted somehow and device is processing and executing fine.
Edit 1 :
Safe mode method using USB keyboard on OTG cable doesn't work. Tried ctrl+alt+menu+prtscr+i several times, it invokes nothing.
Edit 2 :
Tried rooting using shorting to ground exploit, but it doesn't work since serial number of device is too high thus bootloader locked.
Edit 3:
I can see all the installed packages over ADB and uninstall ony of them normally.

Thank you for suggestion. The main question is how do I format USB stick to Android "internal memory" if I don't have Xiaomi 4K stick, like you mentioned in your original post ?
I have another working Fire Stick 4k, and have formatted USB stick using that device, but since Fire Stick 4k uses Fire OS 6, and possibility to format USB stick to "internal memory" is a feature of Fire OS 7, I don't think it will work.
At the moment I just formatted this stick using Fire OS 6, connected using OTG to malfunctioned stick, I can see Fire TV accessing it few times on boot (LED flashes), but after boot I don't see any activity. I will let it sit for a few hours.
