LeEco Le Pro 3 X720 Bootloop problem - LeEco Le Pro3 Questions & Answers

My phone was working normally but after opening a PWA it shut itself down and started rebooting every 30-ish seconds.
To shut it down i have to press the power button for like a minute and I can only get to the bootloader but after loading the screen the phone freezes and reboots after 30 seconds.
The worst part is that it won't charge, when I try to charge it or connect it to my PC with the original cable a red light blinks twice but nothing happens.
It was running the official 5.8.0.28 eUI and the stock recovery.
USB Debugging and developer options are disabled.
Can someone help me fix this problem without losing data?
Thanks.

Do you mean the phone is on but screen is black, or the phone will not power on at all? Press and hold only the power button down for several minutes until it restarts. How is it recognized when you connect it to the PC?

Thankyou for your response.
I can't turn on the phone at all.
It is not responding at all like it is dead.
Tried charging but still no respone.
I cant test it yet on PC but i hope it will start if i connect it to PC.
What i Tried:
-hold power button for 1 a 2 minutes = no response
-charge phone for 4 hours = no led, no display
-tried to bootloader = no respones. I think it needs RMA but it have customrom installed ?. Should i sent it ? Do you think i can try other things ??

Try holding the power button only again for a solid 4-5 minutes. In many cases this has restarted a non-responsive device. Connecting it to the PC will not start the phone. I meant if the screen was off, the phone might be running in download mode, and recognized by the PC. Anyway unlocking and rooting does not void your warranty, but don't offer up that information. As far as they are concerned, your phone is completely stock, and just shut down by itself and now is totally non-responsive even after fully charging several times. Good luck on the button press.

Phone won't turn on

So, my phone is le eco le pro 3, I found this forum through google, my phone ran out of battery and died, then I plugged usb cable to computer to charge it, but the usb port is a bit hit or miss so the connection kept connecting and disconnecting and making that "tut" sound on the pc. After like 20 mins of charging I tried to turn it on but apparently the charge wasn't enough or idk, so I plugged it into the outlet to charge it normally. An hour later, it should be charged enough now to at least turn it on. I hold the power button to try to turn it on, but the "eui" big letters show, flashing with rainbow colors and all that, then sometimes there are small letters that say "Optimizing app 4 of 9", 5 of 9 etc. all the way to 9, then says "Starting apps", "Breaking boundaries for freedom" and the logo starts spinning and it looks like it will turn on any second, but then the cycle repeats all over again, with the eui logo flashing, a few mins later the "optimizing apps" and then the same stuff. I've been using this phone for almost 2 years now, never had any problems with it, it's now out of warranty so that sucks. Is the phone broken now? It won't turn on... I tried holding the power button to turn off and on again but same thing...

As distributor suggested fastboot would be a good place to start. But my guess is that you don't know what fastboot is and you are probably using stock.
If that is indeed the case, the first thing you should check is your cable, it has probably gone bad. FYI: Those cables are notoriously bad. The next issue could be that the battery is going bad, which is also very likely since you have had the phone for two years. Don't worry you can find a new battery for about $15.
I would borrow someones cable or buy a new one and let it charge with the phone off. Next, you probably have corruption which is why EUI is re-optimising apps. If you have further issues after getting the phone charged, backup your data, to your desktop ( if that option is possible...must be enabled) then perform a factory reset in EUI Recovery.
Although these instructions are for a different model , the steps described in the link below are the same for your phone.
You can follow the instructions here to complete the factory reset.

Mi A1 won't start after empty battery (Need Help)

So last night I forgot to charge my phone and when I wake up it's died.
I tried to charge it, but the led is blinking and then it booting up to Mi Logo (not androidone logo, before that, where there is "Unlocked" bootloader word) and it just stuck there.
I can't turn it off, nor restart. I don't know is it software faulty or my power button is not working well.
I've tried pressing power button for minutes, + vol down, +vol up&down, nothing work.
Is there is another way to restart/go to fastboot from adb maybe? (because when I tried to connect my phone to PC, the PC detected it), or if you have any other suggestion, thanks before.
Open the phone and disconnect the battery for a minute and try again
Same happened with me still phone is dead
I think you have to open the phone and disconnect the battery

[SOLVED] Stuck in boot loop: No image, short vibration every ~5s after battery drain

SOLVED: had display repalced.
Hey there!
I've had this Zenfone 3 Zoom ZE553KL for almost 2,5 years now and this is the first real issue I had with it.
One night I went to bed with ~30% battery remaining. When I woke up the phone was dead and holding the power button only made a short vibration. No image on screen.
Here's the things I tried:
Plugging it in: THe charging LED lights up and the phone vibrates quickly every 5 seconds or so
Leaving the battery to drain for 24h: The phone still starts vibrating when I press (or hold) the power button
Holding PWR and VOL+: The phone starts this vibrating cycle agian
Connecting to a PC via ADB: adb devices shows nothing. fastboot devices shows nothing. The phone had USB debugging enabled.
I did those things with and without the SIM card.
Any ideas how to troubleshoot from here?
Cheers!

Not much you can do. Try opening the phone and disconnect the battery for few minutes.

Disconnected for 5 min. After reconnecting, same behavior.
Will try leaving for 1h, although I doubt it would make any difference. After 5 min all caps should be discharged...

The storage is encrypted. The only way to recover the data is booting the current firmware, right? The last backup is a few weeks old...

Yea, it's encrypted by default. No way to recover it really if you don't boot the device into the os.
Also if the battery disconnection doesn't help, try disconnecting different parts that can be disconnected, like the screen, changing port, cameras etc. One at a time.
As a last resort will be to try to bypass the battery or change it.
I had something similar. I plugged it in and left it for several hours (I think about four or five) and then it turned on.
Mine did NOT vibrate every few seconds though like yours but maybe worth a shot.
Good luck and hope you get it working!
It was the display. Had it replaced and now the phone is working fine.
Thanks, guys!

I accidentally dropped my ROG 3. The screen had no scratches or any cracks at all, but the screen had no display. It's totally black. I can hear the sound and the vibration when I hold the power button. No charging LED lights. PC could not detect the phone. Thanks for this post. I need to replace the screen, and it's really expensive.

SOLVED Post update infinite bootloop, restarts before fastboot menu

Hi guys,
one day after some minor update (don't know if it's related) my Redmi 9 Pro started restarting while on the table. I was able to open fastboot, could scroll between options via volume buttons, but couldn't confirm anything with power button. It kept restarting every cca 6 seconds.
After several hours of restarting the battery died.
When I plugged the charger, the phone started restarting again. But now, I cannot even acces fastboot. It restarts before the menu appears.
I didn't do anything with the phone, only updated official actualizations. I have no warranty anymore, its 2 and a half year old.
Any ideas? Thank you!
SOLUTION: After a few hours of googling I found a tip to push power button 10+ when mi logo shows up. It helped.
