Help: G3 doesn't power on - Only blue/green notification light blinks :(

The G3 just dropped down on the floor with the circle case. Then It was working some minutes apparently with no problem, until I myself turn the phone off and restart it. Then the device just didn't turn on. The only thing is that the screen is black and the led notification blinking green and blue
when i connect the charger, the red led blinks once and then disappears, then after 30 seconds the red led appears which apparently shows that the phone is charging the battery. Also When I connect the phone to the PC, a sound of connection is heard from PC but the PC doesn't complete the device recognition process as no new device is found.
I tried to make a hard reset, but nothing happens when I press the power and volume down keys. Tried some other tricks with the battery and the hard keys on the phone but no result at all, as the same story just repeats. Does anybody have a solution for the problem? This devise is the only android device I have

Did you do anything else after/during the time that the phone was off? And is there no possibility that you cracked the LCD digitizer? I mean it might sound strange but this is what I had with my old phone. I dropped it, nothing serious but then I put it in my pocket and upon taking it out I noticed the screen not turning on. As stated above, my digitizer was broken and multiple people told me that the digitizer had a small crack which I didn't notice, then when I put it in my pocket I put too much pressure on the digitizer cracking it. The LED-light did work though, and this sounds very similar so my advise going to the store and asking wether they know what the problem might be.
(Hopefully this was helpfull hehe)

If you Don't see the LG splash screen when pressing the power button it seems like a screen or digitizer problem for sure.
BUT;
after you try turning it "on" let it sit a few minutes and see if you can call your self or send a text to see if it makes noise vibrates etc. to confirm a screen problem.
OR
Also you can try putting it into download mode.
Battery pull (don't turn on)
plug USB into phone but not computer
Hold volume down AND then plug usb into computer
if this comes up to a pic of something on the phone it will be software related. to get out of this mode you can do a battery pull.
Remember to always read up on topics and things you are doing. There are guides here on XDA to help you out.
Hope you get your phone working

I didn't do anything special after/during the time the phone was off. I checked the screen very carefully under a lamp. No particular sign of crack. Thank you very much for sharing ur experience.:good:

I tried to put it into download mode, but no result at all as no connection could also be made between the phone and PC. Moreover, I tried to make a text/call, but nothing is received by the phone. Thank you very much for ur suggestions.

Seems like the drop damaged the memory and the phone can't reload it, you will have to bring it in

Yeah that's plausible ! I'd bring it in too
Hope you fix your phone fast

Yeah... Probably it's a hardware problem. Someone who checked the phone in order to fix it, said that the problem had been with the device board. Even though I was satisfied with the phone, I have found out that the G3 is a sensitive device, as the height of the table from which it dropped down wasn't too much. So always take care of your G3 phone.

Phone does not turn on

Here's the story.
I was playing games in my phone until I slept but forgot to remove my phone from being charged. When I woke up, my phone no longer turns on.
Here are what's happening and current status
- Rooted and has custom ROM
- Currently not detected by Odin when plugged into PC.
- When I turn on the phone, the Samsung logo does not appear. Order of screen appearance is that is is lit up but the screen is still black, then less lit then unlit.
- The scenario above also happens when I plug my phone in the PC but there is no light indicating that the phone is being charged
- I tried the Home + Power + Vol Up or Vol Down combination but the phone does not reset. Recovery or download mode does not show up.
Can anyone help on what happened?
Regards,
Cedrick

UPDATE
Phone can now be detected by Odin. I can flash the Bootloader and TWRP recover. However, there isn't anything that appears on the screen of the phone. Do you think this is more of broken LCD?
Also on the screen, there is a part that is white and this is the hottest part. The phone is gotta be warm when turned on but this part is too hot.

Xperia ZL weird problem

Hi All,
I recently tried to fix my older sons xperia zl, The phone would not power on, it did not show any signs of life when plugged in to a computer. Tried all the different button combos and the off button at the back of unit but still nothing.
So I opened it up and checked each component visually, did not notice anything wrong.
I decides to see what would happen if I disconnected the battery and plugged it in to just usb to the computer.
Well it showed up in device manager as a SEMC flash device, and the red notification light came on. Then it started to try to turn on without me pushing the power button, the screen gets to the sony logo and then goes black and starts again.
The next thing I tried was to flash a new rom to it, under Flashtools it automatically goes in to flash mode, found my rom and hit flash and it completed the flash. Disconnected the usb , connected the battery but nothing no power and still nothing in device manager.
Another weird thing that happens is that while the battery is disconnected and i hold the vol+ a blue notification light turns on and the phones goes into fastboot mode.
I initially thought the battery was the problem so I ordered a new one and installed it but the same thing keeps happen, anytime the battery is connected the phones does not react to and buttons, even when the usb charging cable is also connected.
I am wondering if someone has a schematic or know of a capacitor, resistor or fuse that is stopping the phone from recognizing the battery.
Any help would be greatly appreciated.

HTC 10 Unresponsive & Can't Restart But Alive

I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.

Stuck in low battery boot loop

Hello, Huawei gadget friends.
My watch started to go in to a "low power boot loop" a week ago so I left it alone hoping a full drain would restore it back to working condition, but alas not.
So now this is the situation:
1) press button, nothing happens
2) connect to power shows the charging icon (white battery with power sign) and then after a few mins commences a boot loop as follows
3) from the charging icon, then gives the "Device software can't be checked for corruption..." message
4) followed by the red Huawei logo, then a single vibrate and then back to step 3 above
5) removing the watch from the charger stops the boot loop but then shows the low battery icon (white battery with one bar).
In one or two occasions, I saw it boot up to the colorful spinning 4 android wear logo, but did not complete (did not show "Android Wear" before rebooting again.
I have tried getting it to recovery mode screen or fastboot but without success -- I keep getting the second buzz without fail.
When the beta of 1.5 came out, I tried it, but since then, have wiped my mac and don't have the adb/fastboot software anymore. From reading the forums, there is now some new software called TWRP. Please advise what I can do.
Would I be right to suspect that it is some battery problem? Is it beyond help? :crying:
Thanks in advance!
MMM
Edit: I have also left it on for several hours charging (and rebooting constantly), thinking that perhaps it is just low battery -- but no success.

I'm experiencing the same problem, i turned it off yesterday at 17% and connected to the pc this morning to charge. I immediately noticed that it started looping with the white icon and it doesn't turn on, nor boots into download mode.
Have you found any way to restore it?
Mine doesn't show the red HW logo, charged for some hours and nothing.
I noticed that the pc see that there's something connected, but keeps saying "USB not recognized". I don't know what to do, i may open up and disconnect the battery
EDIT: SOLVED, it was just the cable that broke somehow. I soldered a new cable to the circular base but that didn't work, but as soon as i received this i connected to the pc and started pressing the button randomly till it showed the battery logo and started charging

I got this when I plugged it into my laptop. Plugging it into a dedicated USB charger solved my problem - I suspect the power rating on the USB socket wasn't high enough to charge effectively or that the USB socket is faulty in some other way. From what I understand, not all USB sockets are equal in that some are suitable for high-drain devices, some not so much. So trying another USB port on your computer may also help (Unfortunately at the time I was backing up to an external HDD on the other USB so that option wasn't open to me).

guyz, i have tried my method it actually worked on Xperia X Perfomance
When it goes to Bootloop for Drained battery, i just plug the cable and perform activity block method By pressing and holing power and both volume up and down and when it hits the 1st viberation i just simply release the key. (remember dont hold it too much long after 1st single viberation just release the keys ) and your phone will go to block activity mode. charging light will change it colors from red to blue.. after 2 minutes just press power button then you ll get another viberation and your phone will be seen as charged 2% and then it will be normal again...
i think it happens when battery drained and phone is unexpectedly trying to go boot in first place.
thank you
