Only led turning on

Hello! First of all, sorry for my bad english
It all started when i unplugged my moto g from charger, the charger and the phone were way too hot. After that the phone won't boot up. Only the white led is turning on when the charger is plugged, if you press the power button or any combination of buttons nothing happens. So i went to the Motorola assistance, they wanted to charge me 360 R$ which is about 100$ dollars. They said my board burned . They also said they found some water damage but when i opened it everything was perfect. Nothing smelling like toasted or any sign of water damage.. So any ideas? I already tried holding power for 2 minutes, volume down and then power, put it on a stronger charger (1A from a Zenfone).
I'm not buying the burned board cause it turned on, for just a day after the assistance diagnostics ..
Again, just to be clear, the led isn't blinking like the battery died...

You could be one of those unlucky ones that bought a Moto G with a faulty motherboard that won't come back to life after their battery dies. Or maybe you didn't do the method correct?

I don't think so, the phone died before but always returned to life. I did a lot of methods, none worked. Power for 2 minutes, vol down then power, unplug the battery put the charger and then put the battery, i already leaved it on the charger for more than 12 hours and nothing. Only thinking working its that ****ing white light..

Was your phone unlocked? It's odd that a phone melt down just like that.

Nope, not even rooted, not even apps outside play store

What was your phone usage that day.
I think everyone's phone do get hot when 3g/4g data is enabled.
My phone gets too heated up after playing coc for like one hour (sometime on charge or battery)

Normal use, only listening to music and stuff. I was at home so it wasn't connected to 3g.. I put it on charger with 5~~10% of battery left and 2 hours later the charger and the phone were burning. I unplugged and that was it, only the led turning on with the charger on and nothing else.

Have you tried replacing old battery with new battery??

I 'm with the SAME problem . Only flashing white LED and nothing else. I plug the charger and nothing happens , only the LED . I've tried to use a more powerful charger but not resolved . I have to put it another battery charged but not resolved . Some hint of what can be done? It is a XT1033 .

One time and only one time only my moto g worked. I unplugged the battery, leave it there for a few a minutes.. actually, watch this on youtube >>qZhAabwi24M<< (i cant post links yet) (How to fix a DEAD Moto G if ALL ELSE FAILS! Guaranteed!! by Kyle Sanders)
it worked for like, 2 days and suddenly the battery showed 0% and that was the last time I say my moto g on :crying:

Dead Nexus 5?

I just got this very neatly used 32GB Nexus 5 and on arrival yesterday afternoon it worked well except for the reboot problem the seller indicated. I flashed stock all over and rooted and installed ElementalX kernel for tap to wake and everything was going well, until last night when it just up and died on me. I thought maybe the battery was drained and I plugged it on the charger. It wasn't charging so I left it overnight. On waking up the phone is still dead. Doesn't charge, doesn't boot, nothing. I've opened it up, disassembled it to check all the parts, and everything looks fine. I also tested the battery by touching the tip of my tongue to the connector and I got the normal tingy feeling indicating the battery still has juice in it. I also checked the two LDIs and they are all still white; no water damage. I'm just at my wit's end now and considering getting another motherboard if that would fix it, but I just want to ask if there is any hope through any kind of fix before I commit to getting a new motherboard.

It might be that ?

Thanks for your response but my phone is not even booting up at all. It's just dead. Not booting, not charging, nothing. Thanks again.

IF you press power and the volume buttons and connect it to computer, did you have in device manager something?
If it was something like QHSUSB ... you can try that (it use and LG debuging software who reflash the nexus all at stock like in the factory) : http://forum.xda-developers.com/goo...-unbrick-nexus-5-stucked-qualcomm-hs-t3043301
If not it was possible that the EMMC is dead
I hope i have help you

I tried that but nothing comes up in Device Manager at all. The computer does not detect the phone in any way at all too. I think the motherboard is dead. I ordered another working Nexus 5 with a broken screen on ebay to use and swap out the motherboard.
Thanks for your replies. I appreciate it.

Red Blink Errors - No Screen

So I have no idea what's going on with my phone:
It consists of 3-4 sucessive red LED flashes, can see a charge icon on the screen for like 0.25 ms (literally haha), and then it shuts off and this process just repeats.. any idea what is going on?
I've attached the video here: https://youtu.be/rnW2euEdKaE
If it matters: The screen was cracked, and subsequently replaced, but that was some time ago..

Hi,
Did you try another charger ?

Definatly for some service

I was having the same issue... Try holding the power button for 10-20 seconds too and see if that brings it out of its coma...it helps with my phone

Hey all, thanks for the suggestions.
1. I tried different charger, in fact 3 different ones.. still nothing
2. Service? What kind of service?
3. I held power down, it gets to the huawei splash screen, for again.. 1 sec than restarts
Any other suggestions, thanks!

I don't know if it's exactly the same thing, but perhaps Is this a way to make your phone working again

Tried that, took the battery out, plugged it in.. no more flashing red LED.. i see the huawei screen now, but it boot loops. If I insert the battery in while its plugged in like the above, than it does that led flash, and no screen.. so i'm thinking bad battery??

It's certainly the battery,
Last time your phone was working, did you use all the battery (until 0% and then power off by itself ? )
You can search a new battery on the Internet,
With the Model code at the top of it, you will find easily a new replacement battery)

If your battery goes under a certain level of charge, ie close to 0%, it's possible the onboard security prevent it to charge normally.
You can try the freezer trick, it helped me to recover an ipad with the same condition.
-Put your phone in a ziplock bag to prevent frosting and humidity.
-Let it rest at least 1h in the freezer
-As soon as you get it out of the freezer, plug it in a wall charger and wait at least 15 min before turning it on.

You should claim your warranty, contact your vendor.

I don't believe so, Its my backup phone so there is potential the battery would have hit 0% as I don't frequently use/charge it..

Hi there.
Did you managed to fix that? I have same problem. I just replaced screen with new one.
Firstly I connected new screen to motherboard and it worked perfectly. I put it all together, glued new screen to frame, connected flex'es to mobo and... nothing. Red light blinks, and screen flashes with "HONOR powered by Android" screen if I disconnect battery and just plug to usb.
Battery is not a problem, before repair it had about 70%, and now it's voltage is around 4,05V.
Any ideas?

same thing was happening to my huawie honor 8 for some time now... i brought a new screen n that didn't fix the problem ,,,,, the person that fixed the screen for me said it needed a power boost( or something to that extent) n in like a hr or so after not being able to start just the screen blinking it came on!!!!!!! i was ecstatic tbh... sadly like a week n a half- a month later the **** stopped working again ... the red light comes on when it charges n every thing but the screen doesn't fully respond just stays blank. i definitely think its a battery problem but not too sure

Shutting down after startup

Hi,
there are some threads about the bootloop problem, but I couldn't find exactly same problem: some days ago my phone landed into the bootloop. It was a bit spooky with battery charging state, it was jumping for different states - 3%, 99%, 24% after every loop. So I bought a new battery and replaced the old one. Now the phone starts to LG logo (with starting sound), but after 10 seconds I can hear the power-off sound and the phone turns off. It seems to be a "normal" shutdown, not the "reset-bootloop": I hear power-off-sound, LG-power-off-logo and LED is blinking blue for about 10 seconds. After that it repeats infinitely. Also, if I turn the phone off it stays off, but if I put the charger in it, it's starts from itself again and again. Did not tried the hard reset until now. Any ideas, guys?

update: tried hard reset. it's starts until "optimizing apps", if it's done, i can see for a second the "first setup" screen and then it's immediately shutting down. same problem with the old, original battery.
edit: for the first time I saw message "high temperature" on the screen, before it was powered off. But the phone is not even warm...

What you describe is exactly that happened to the Mrs's GF2. One day it was fine and then all of a sudden the battery drained really quick. Now she can only get to the optimizing apps screen before it shuts down again. Ordered a new battery but that doesn't look to be the solution from your findings. :crying:

My phone has the exact same prblm n i was thinking of buying a battery but now that i have read your post i am doubting my battery purchase.
By the way have u found any fix also are u sure the battery is genuine n not some poor replica?

I had this problem when I had flux in my battery port causing a battery connection problem. Sometimes it said temperature too high and other times temperature too low. I was able to fix it by taking out the motherboard using 90% alcohol and a toothbrush to clean the battery port in the motherboard. Then I let it dry and problem was gone. Now I'm not saying this is exactly your problem but it just means that there's most likely bad connectivity to your battery. It could be your battery, the cable or the port.

Mrs received her new battery and it seemed genuine. Put it in and the phone is 100% dead. No power, no charging, no life.
Its not all bad news as she bought a Honor 6X which is a far better phone.

I tried all the hints I could find (except cleaning it with alcohol), but nothing help to start the phone again. Could be defective heat/temp sensor on the motherboard.
Battery was from "Polarcell" - that's a pretty good one manufacturer with satisfied user reviews on amazon (also had good personal experience with their batteries). Just for info: phone doesn't even start with original battery anymore - same problem.
I already switched to Honor 9 (excellent phone!), but will give another try and clean the battery attachment port with alcohol today. Will give you an update later.

If you plug the phone into the charger does it even show the battery charging symbol at all?
From what I've been reading the temp sensor is in the battery and sends the temp signal through the battery connector to the motherboard. So if you replace the battery it's like plugin in a new temp sensor. However if the connector is bad then that's the only thing that I can think off that would prevent the phone from starting. If the port is bad I don't know if it can be fixed or not.

Had no luck yesterday with port cleaning. Still the same error.

Yes, but it's more complicated. If the phone is turned off and you plug USB in, it starts to boot from itself (without pressing the power button). In most cases it's going up to LG logo and powering off again. After powering off I can see battery charging symbol for about 5 seconds, after that it's changing to battery symbol with an thermometer. While the phone is in this bootloop, it's charging. From the point with this battery temperature symbol it stops charging. I read something on reddit about getting it up to 100% could solve the problem. So, I tried to plug it on and off about 50 times to get fully charged, got it up to 100%, but it's still rebooting. Can't get into recovery, but it's possible to get into the "hard reset"-menu, where I can wipe data. After this the phone boots normally (at the first sign), it's starting optimizing apps, I can see the "first-setup"-screen (that one with language chooser) for a half second and it turns off again. Same behavior with both batteries - new one and the original.

That's a lot of combined symptoms. I have no idea what could be wrong with yours exactly. I would try to bake the motherboard with solder flux as a last resort. I had to do that with my G flex 2 twice to bring it back to life. I'm not sure if it would fix it in your case, but at this point you don't have much to lose.

I've already spent enough time with trying get it back to life. Loved this phone, but I had to send it to LG service every half year (3 times!) and got it every time with a new motherboard back. My brother had to send his one two times within a year because of several problems (no vibration, no sound through 3.5 jack...). Furthermore it was not possible to root or unlock the bootloader since Android 6 (what I've got with the last replaced mainboard, but what was not available through the software update!). So, just for me it was a very bad experience and for sure I'll not buy an LG phone for the next 10 years.

Oh, that might void your warranty if you changed battery yourself. As I can see you're from Germany, EU, so you should ask for DAP (defective after purchase) act from service to get refund for your phone.

I've never heard about DAP. Do I give them my phone and get from them some money back or what is that about? Is it an manufacturer service or general refund possibility in EU?

I assume it should be available in EU. You should contact your seller or the service about if for detailed info. When you dave details about that please share them here.

OnePlus 7 pro only turns when connected to charger of if power button is pressed

Hi all
So yesterday, my OnePlus 7 pro “died”. The phone can only boot when connected to the charger OR if I keep the power button pressed (if I release the power button, and it’s not connected to the charger, the phone instantly turns off – I kept pressing the power button and the phone completely booted, and the battery was at 100%).
Already perform a hard reset (Vol down + Power) and checked for software updates. The only menu that doesn’t turn off immediately is the fast boot.
Do you have any suggestion?
Thanks in advance.

Battery or mobo failure...

Thanks for the quick reply
is the fix included in the manufacturer warranty?

If under warranty, send it in.
Check for rear cover or display bulging, a indicator of battery swelling.
A swollen battery is a failure, do not attempt to charge if so.

it's still under warranty, i will check with the shop
the battery is not swelling, there is no noticeable indicator of that.
Do you think it might get worth trying to use MSM tool or use try to mess with fast boot?

and why can i use my phone normaly when charging if you say is a mobo failure?

The mobo controls charging and almost every aspect of the phone's operation. Failures manifest themselves in a variety of ways.
It could be firmware.
If under warranty it's best to just use that if you don't know what's wrong...
