Hey guys i hope someone can help me out : )
Problem:
I froze some system apps on my xperia pro including mtp (the one that you need for the usb to connect to the computer)?!
well then i was using the phone like regularly and it suddenly froze.
Rebooted the phone ..black screen , the phone is booting normally but i cant see a thing of course.
Fastboot / Flash mode
With flashtool It says its connecting but then i get an error
With the cmd fastboot method its just stating "waiting for device" and when i connect it in fastboot mode nothing is happening just windows telling me thats something wrong with the usb connection and it wont work.
When the phone is turned on and connected to the computer i can see it listed in the device manager as mk16i
if that is relevant
Thanks for reading.
problem 1 : is your phone hardware qwerty button light up when you turn it on and dim when wait a few second? if similiar like that maybe you need to replace the flex cable
problem 2 : try reinstall your phone's driver and make sure you connect the phone in fastboot mode with blue notification led light up.
So I bought a used G3 knowing about the issue it had; it didn't boot. I thought I could find a workaround to this but the phone doesn't boot, doesn't enter recovery or download mode. All the info I have is that when I take off the battery the pc sees it as an unknown device, while it's connected I press the power button for several seconds and it disconnects from the pc, reconnects after several more seconds of pressing the power button. Screen remains dead. Seller told me he had a perfectly working phone before he tried to root it and it never turned on again. One more indication is that the LED notification only flashed red a few times when I connected it to the wall charger and that was it. No LED working after that. I'm open to any suggestions though I guess I'm here for someone to tell me there's no hope reviving the device. Thanks in advance!
Same proble with mine but i bricked mines when update to lollipop and never turn on again . still waiting to some one help to revive my LG
If I come across any solution I'll post it here. In the meantime I've tried the following method on a freshly formatted laptop and I still get "Unknown Device" in Device Manager..

same here
same problem, someone told me that if was the board or something like that and that it only can be fixed with a complete replacement of this, also, that it could be fixed with linux using comands to install .APK or .TOT.
linux sometimes sees it as Qualcomm CDMA Technologies MSM QHSUSB_BULK, using a virtual machine of linux ubuntu, windows 8.1 sees it as unknow device
LG dead since 3 months ago.................. i wasnt using the phone at all when this happended so........... :crying:

I tried using a boot usb drive to see if ubuntu saw the device but it didn't. Maybe there's some things needed that I didn't do. The thing I don't understand the most is why do windows see it as an unknown device only with the battery out while if I connect the G3 with the battery on, it doesn't show anything on device manager..

Hi there.
Please check these 2 threads out and see if any of it will help you. The one for the G2 can also be used for G3.
Here are the links:
http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091 With this technique you would have to find the software online somewhere but this method does revive dead G3 with these symptoms.

If I helped somehow, hit the THANKS button.
Good luck!
The thing is I can only get the device to be recognized as an Unknown Device in Device Manager and only with its battery out. If I keep 'volume up' pressed nothing happens, it's only shown after I simply connect the USB cable and it pops up after 10 seconds or so. It's very consistent in the way it behaves..
A small update, sometimes when I pull and put the battery again, I connect the phone to a pc while holding down vol- and the pc makes the connected usb sound while the phone led is blinking red for a couple of minutes, then it stops. That's about all there is concerning the phone giving signs of life..
First of all I'm sorry if I posted in the wrong section
The problem of my phone is that it is apparently death. I don't know why, because I was using it normally and then after few minute, like 5, when I tried to use the phone it seems to be death. It won't turn on, even when a charger was plugged in. The phone just shows a white led blinking. I tried to turn it on and nothing happened. So I tried to power it whit the volume down button pressed and the fastboot mode appeared. It says battery low (charging) and if I try to choose one of the options nothing appear, just the white led blinking.
I don't know what to do, I would be happy al least I will recovery my internal data (with the app data) using the fastboot mode.
Sorry for my english, I'm begging help.

Just this morning I replaced the battery and the phone is back alive.
Btw thank you for the help!
I've got a dead oneplus 5t from my son. It was not charging anymore.. So I've replaced charging cable and battery.. Seemed to work it was charging... However it doesn't boot... No logo screen screen stays black/blank.
Tried several suggestions on this forum to get into recovery mode, fastboot mode... But still nothing. Only vibrating works after a few seconds.
So tried to unbrick with OP5T_Unbrick_tool_dumpling_43_J.40_181105(OOS.5.1.7) and the qualcomdrivers..
I was able to install the drivers and I see they are installed in devicemanagement.. and an empty folder create for oneplus.
I charged the phone all night and was able to download the upgrade. It then says download complete and I tried to restart the phone..
Still just vibrating but nothing happens.. Seems like everything has vanished from the phone, no recovery, no bootloader, no files.
So how to proceed to get all the stuff on the phone? And maybe the displayscreen is dead, but how can I tell?
Also tried the SMT upgrade. Strange thing is the device and com port are seen in devicemanagement and active when I connect without volume up, but cannot start because it says When I try to use smt mode the program says: "This COM port is disable by user". With volume button up pressed and then connect, ledlight turns green but the qualcomdevice is grayed out in devicemanagement and it says waiting for device..
Any help is welcome. I am a noob in how to proceed on the phone however I have an IT background.
Spent already so many time figuring out .. maybe it's effortless and its for the trashbin.
Thanks in advance
SOLVED
I opened the phone again loosened all those tiny connections to battery, screen,charger, mainboard and re-attached them.. Somehow a connection seemed to be fitting allright as yI looked at it, but apparently wasn't :good:
Hello everyone,
I really hope somebody can help me with this.
I have xperia z5 premium, power button stopped working a month ago or something, but the phone was working perfectly fine. Of course, I made a mistake and did not charge it in time and it turned off. Now I can't get it to turn back on because the button is not working.
I explored all my options and I realized I can do fastboot reboot through fastboot and adb. However, I can't seem to get my phone to go into fastboot mode.
I hold volume up button (which I know for a fact is working), I plugin usb, and instead of getting that blue led light everybody keeps talking about, I just get a red led and then a green one after the sony logo that signals the phone is charging.
I installed ADB and xperia z5 premium drivers and I still can't get it to work. When I type fastboot reboot it says <waiting for device> when I try adb reboot or adb reboot bootloader it says "error: device not found".
I've also installed xperia companion app and when I plugin my phone it shows a screen where it says: "Your device is locked
1. Unlock require
Unlock the device using password or fingerpint if needed
2. Allow data access
On your device, select the option to allow data access"
I've tried doing the same thing with adb on two different pcs, always get the same result. Phone just gets to charging screen and keeps charging instead of going into any mode.
I also tried holding volume down button and plugging in usb which is supposed to be recovery mode or something, but that doesnt work either, I also get charging screen. And I'm 100% sure both my volume up and volume down buttons are working.
What am I doing wrong?
P.S - Debugging mode is not on, im 100% sure since i never turned it on.
Somebody please help!
Thanks!
