[Q] my device does not start !

Hi
My tablet was OK since a few days ago, not rooted, nothing strange installed on it.
For a few days, the device (turned off I suppose) does not display anything or even respond (haptic feedback) at all when I plug it on the USB cable. The screen keeps being blank (actually black...).
I tried to keep the "vol+ + power" buttons pushed for a while, but not lucky, it's really such as the device USB connector is KO. Is it possible ? I do not see anything strange when I look at it...
Is my device dead ???
Do you guys have any idea of how I could make it work again ?
Thanks
Nico

Try holding volume down+power to get into download mode. If you can get there then it can be saved. Look in my signature for links to flashing stock firmware and more for a solution :good:

Almost forgot, try another USB if yours isn't working, always use a good USB cable if you gonna flash stock firmware

Have you tried leaving it on charge for a while first?
Also, because you are not rooted you can claim the warranty if it doesn't work

I will be in vacation for a few days, my device will stay home trying to charge during this time
Regarding the warranty, I would like to avoid having to use it.

I bought my P600 refurbished and it ran into some issues a few days after. I already voided the warranty so I've been looking around for resolutions for my problem.
I did see some people have the same exact issue you had. This is all based on the research I did trying to fix mine (which is not the same issue you are having).
WARNING, THIS IS ONLY BASED OFF OF WHAT I'VE READ. I DID NOT EXPERIENCE THIS NOR DID I VERIFY IT. JUST PASSING ON MY KNOWLEDGE, SO DO AT YOUR OWN RISK!!!!!!
Apparently when the screen doesn't come on its due to only a few things. Its either bricked, has bad hardware, or lastly, which is the most common, is that the LCD ribbon cable came loose. You have to open it up and check reseat it. But then it would come undone again. Someone used electrical tape and the issue was resolved. Once you open it, the LCD ribbon cable is on the left.
If you don't open it properly it will show signs of being opened (chipped plastic bezel), so only open it if you think you can do it carefully and are not wanting to send it in for warranty.

Not Charging - Phone is Dead

I have a Zenfone 2 551, 2GB/16GB. Bought it 45 days ago. I bought an Asus Fast Charger later on. The first time I wanted to use the new fast charger the phone turned off.
I change to a regular charger and the led turned on (I had 40% battery at the time). Left the phone charging (standard original Asus Charger) and the battery instead of charging is loosing charge. Even with the led turned on.
Eventually the battery died. I tried other chargers. 1 out 10, maybe a got the led back on, but the battery stayed on 0% and wasn't enough to even turn on the phone
I've read several people having this same issue.

In one of the post someone wrote this tip
Thanks for the reply. But after a long day of stressing, it worked by itself. I read from an article about another android with quick charging that the USB could have not been all the way in in the adapter which, in my opinion, it was but regardless I repeatedly unplug and plug(15 mins -30 mins interval)... did the same with the phone plug and unplug till I saw the battery level going up
It didn't worked for me!
I've already tried:
a. Changing chargers and cables
b. Pressing power for 20 seconds
c. Pressing volume up + power
d. Plugging and unplugging the phone every 15 minutes
I bought the phone while visiting the US (I don't live there).
Has anyone else had this kind of problem, and was able to fix it?
Thanks

Can you confirm if the ASUS adapters/USB cables work with other USB devices? Have you tried charging from a PC? If so, unfortunately this issue sounds like a hardware related issue and will require sending on for warranty service. Please feel free to contact me direct at [email protected] if you have any questions or concerns.
Sincerely,

my phone died yesterday like that. i connect my phone to my computer with Asus usb cable the one comes with phone. my phone screen cracked about 1 month ago but it was not disturbing me so i didn't repaired it. right now nothing works on the phone.. at the moment i connect my phone it turned off and for 1 sec battery screen appaired then nothing. can't see my phone when i connect to pc with adb or something like that too so i think problem is more then screen but any idea ? @Asus_USA @Asus

The guy uses a metal tip pin to release the battery connector? seems that is risky and may short something out. These asus phones have so many issues, that's for sure.

plug into pc see if its even recognized if not lg waranty or a new battery

Try these steps
Hold down power button for 30s at least and try power again
If that doesn't work
Pull battery
If that doesn't work
Pull Battery and clean prongs where battery connects and battery prongs
Try different charger
If that doesn't work
Clean charging port with toothpick GENTLY....again GENTLY and dont jam it inbetween the side it doesn't fit where connector is

I have the same problem since today.
Does not start, not even Download Mode is accessable.
Seems like I have to send it to repair, but then I'll lose my data right?
I have data that I don't want to lose on that :/

Did you try steps I posted

Except for the different charger I've tried the options.
I think a different charger would not help anyways :/

plug into pc and see how device manager reconizes the device

Consider another charging block
If not go to local repair shop have them test the charging port for voltage
---------- Post added at 02:59 AM ---------- Previous post was at 02:56 AM ----------
Also try this....hold down the power button 30s
Considering you can't turn it on
Charge it for an hour or so. Battery might be completely drained
If your charging block, battery doesn't need to be replaced, and charging port has voltage
You would need to send it in
---------- Post added at 03:01 AM ---------- Previous post was at 02:59 AM ----------
Easy way to check the charging port without going to shop is
Does the cable going into charging port wiggle around and is loose? Or is it firm

He took the battery out and connect the phone to the computer, it's recognized as Qualcomm 9008 (or something like that). Is it the famous bootloop or is there anything we can do?
Thank you

My phone is not recognized at all
Seems like I have a worst case scenario :/
I only see a battery symbol containing a question mark, but the PC itself does not seem to recognize the phone.

If he was not doing anything. Like trying to root it or downgrade then yes. Basicly bootloop. Lg waranty. If he was rooting or dowgrading. There are a few guys that may hve fixxed it but its a long complicated prosscess.

Yours may only need a battery. Leave battery in and plug into pc. Does not need to be out. If u still get the batt with x u most def need a battery

Looks like LG warranty is a bit out of question, it's passed already.
Any suggestion perhaps? no problem with "long complicated process", at least we can learn something

If I have the battery in nothing happens. If I put the battery in when the display is showing the question mark, the display shows nothing anymore.

You might be able to follow the lgg4 hardbricked threads. Theres a few diffrent ones goin on now. In the generalsection. I dont own a g4 anymore. So if its changed and is bootlooped u may be able to disable the big cores. To stop it from bootlooping. Dont get hopes up yet. But thats a start

We've checking a few, seems like root is needed. Do you know how to root it? it's H818P MM, can't find it so far.
And there's a bit update. The phone was a few months died, now after I charge the battery using external charger and trying to turn on the phone. There's nothing happened, probably because the juice is not strong enough, but now there's a battery animation with a question mark when I connect it to the computer without the battery (still recharging the battery again).

Let's see how will it be. Thank you

Yes order battery
The only reason why ? Shows up while charging is if I pop out the battery and have USB cable connected to phone
Your batter may be completely dead
Mention this before

This is a common issue, it happened to m last month. You can try anything with you PC it wont work because the problem comes from the main board.
Just contact LG and get your phone repaired.

U can replace bottom USB board first to test if the connection is dead. It's like 3$ from AliExpress.

Galaxy Note 10+ just shut off

Hey all,
I have an ATT Samsung Galaxy Note 10+. It was working fine, plugged into the wall to charge, and then all of a sudden it just shut off. The screen went black, I saw the ATT splash screen and then it turned off, and I cannot get it back on. When I try to start it like normal, all I see is a faint line that shows up intermittently. Any help is appreciated.

When you plug it in are you able to see the charging animation?

No... nothing.....I tried to hit volume up and power, and one of the splash screens appeared for a split second, but other than that I havent been able to get it to do anything.

I don't know sounds like a hardware thing to me probably will have to get up with Samsung about that.
Maybe someone else will chime in ideas. Sorry I couldn't help you more.

Sounds crazy but try using a computer to charge. It may need a lower wattage charger. And also see if the computer recognize it

Yeah sounds like it. My fault I forgot the most basic rule of troubleshooting look at the simple stuff first :laugh::laugh::laugh: I should have asked the obvious questions even though you said it was charging. Glad you got it figured out
