[Q] reset motherboard on lg optimus black

Hy... I tried to do an upgrade to my optimus black from 2.3.4 to ICS and after the phone virtually died and everything I do no longer starts. Can someone help me before I go with him to repair? I think the problem would be the motherboard, so if someone who might know a solution, please help me. Thanks in advance!

does it enter software/upgrade mode?
pressing and holding volume up while connecting to a pc while phone is off

does it enter software/upgrade mode?
Unfortunately does not start in any way. I've tried all the ways found on the internet and nothing.

Welcome to the forum. Thread moved as questions belong here in Q&A so please post in the correct forum going forward.
Thanks
AvRS

Simple test: Phone should be off, take akku out, hold vol+ button while you connect via USB to PC. If it shows something like SW upgrade with a yellow background on the screen good, if screen stays still off it's a hard brick - i.e. you probably can't do anything.

Unfortunately does not work any combination of keys. I think the last option is the correct and I do not have what to do than to send to repair. Thanks anyway

[Q] [Q - Urgent Help!] (Root + Locked Bootloader) Xperia Z can't start!

Hey Everyone,
I am stuck right now and I am not sure where to go from here. I am not going to go into the story on why it happened, I'll just tell you guys what happened to makes things easy.
I rooted my phone without unlocking the bootloader using this method:
[ROOT] Xperia Z for LOCKED, UNLOCKED bootloaders! [Exploit by: goroh_kun & huhka_com]
forum.xda-developers.com/showthread.php?t=2186368
Using ROM Toolbox Pro I attempted to change the background colour of the status bar.
Phone was restarted by the app.
Problem begins:
Phone won't start.
It will boot with the Sony logo, followed by the XPERIA logo... followed by it shutting down.. and it will keep repeating this until I force shutdown the phone (Power + Volume Up).
I can connect it to the computer via Fastboot Toolbox using the Fastboot tool. I have no idea where to go from here. I tried to reflash a generic .ftf rom, but I am just stuck at the part where it's telling me to unplug USB and reconnect it while holding back button (Volume Up for Xperia Z?), but it does not register it.
Any advice or solution would be a great help as I've tried searching around and could not find anything for hours now..
Thank you everyone in advance and I really appreciate it.

Thank you very much for the prompt response. Good to hear from someone after being in the dark for hours searching.
That was the first thing I've tried doing, but the update service requires the phone to be in an on state to begin with. Will revisit that option again in case I missed on something,

Yeah.. I see that it's different..
I'm now stuck at the "Connecting your phone" holding the volume down key bit, it'll detect a device, installs the drivers for the first time (SEMC Flash Device), but nothing happens. This is what happens.
*Holds Volume Down* & Plug in USB
SEMC Flash Device can be seen connected under Device Manager>USB controllers
*silence*
SEMC Flash Device disconnects and phone reboots into the previous state (Sony + XPERIA logo, restart)

All I did was switch off your phone, Keep hold of volume down and plug your usb into the phone. Your phone LED will briefly flash Red then Green

Mine is not flashing any colour. I will hear the USB connect tone, and that's it. Nothing happens. No LED flashing, no moving of the update software. This will then be followed by a USB disconnect tone after a while and back to the loop again, Red LED>Sony Logo>Red LED off>XPERIA logo>phone switched off for a brief moment only to loop.

Maybe restart the pc and change the usb port that you are using.

that sounds like you have the phone plugged into USB ? you are supposed to start Sony update without phone plugged in...and only plug it into usb when the sony update prgram tells you to, then you are only to plug just the USB cable into computer, make sure phone is completely off , wait 30 secs , hold down the volume key then plug USB cable into phone,

Looks like it's my desktop thing. Restarted the thing 3-4 times and swapped to almost every USB port at the back.
It's being detected by my laptop. Will update everyone on the progress. Looking good so far. Thanks for the support so far, really appreciate it.
Edit: Download complete. Installing software in the phone. Looks like it might be going well. Stupid desktop, I thought it was an issue with the phone all along. >.<
Edit 2: Running fine now. I see the colourful smoke animation. Cheers. Now if only I can buy the three of you coffee. Cheers

Bootloop

hello, just a question. after installing the trinity custom rom, i installed the fullscreen toggle app. aftr that my phone just turn off, im not stuck on the sony logo, my phone shows the sony logo and after that, it shows again. i tried to hold the button at the back but it doesnt turn off the phone and doesnt vibrate.i hold it for 15secs and up but the phone turn off and turn on again after 2 secs. by the way, my phone is charging if i connect it to the charger. i cant connect to the flashtool. how can i fix my phone?
will i let my phone just become low battery for it to turn off and then charge it again? how long will it take for it to become low battery? my phone is heating up because of the on and off thing.please help me.

I had this issue and sent back to Sony under warranty, had notice to say should be back in 24-72 hrs.
If you don't have option to send to Sony try phone store and get them to remove battery and flash stock again....or if feeling brave do your self

Glad you got it sorted.
How did you turn off as your original post said you couldn't, just in case it happens again to me when flashing mods.

i hold on the power button (sleep/wake button) and the off button at the back. i hold them at the same time. after feeling 3 vibrations, release the power button. the device should turn off now. when you feel one vibration. it doesn't turn off the phone. the phone will just boot up again.

isnt there a soft reset button on the back of the phone (you know the button you use a pen to press it).

Hi, I have the same issue and I try this solution but it didn't work for me.
Because I want to try the trinity vengeance rom and I'm scared that if I have a bootloop, I can't turn off my phone.
Sorry for my english ^^

Hi, your problem is solved?
Edit: I found the solution in the other topic in Q/A.
I hold the power button with volume up and the off button at the back.
I wait 3 vibrations and the phone turn off. Thanks to xda community

Thanks to your guides I have found out a full solution for this. I'm come from Trinity...'s rom and have bootloop too.
1. Keep the device connected with PC by USB cable
3. Open and prepare a firmware in Flashtool
4. Flashtool notifies to have your phone connected in flashmode --> It's time to go
5. Press and hold combination of Volume Down + Power + Reset
6. After 3 times vibrating with GREEN Led blinking, have your fingers relaxed and your SP's been in flash mode then :good:
7. Bear in mind that you should be careful for the next time playing with Rom and mods! :laugh:

When you hear the three times vibration then you shutting down your phone and after that the phone is turned off completely, then leave it under wall charger via USB or Dock for minimum 4 hours, if it do not turn on then you have to flash a new Firmware OR Repair via PC Companion. Download Official Sony PC Companion and repair your phone. Other way is to use Flashtool and download the latest FTF from Mega Collection and flash it. Then it should turn on.

hi
i have the same problem with my z1 xperia
the pc companion wont see my phone to preform any kind of repair
any ideas
thanks

if nothing is happening just the LED red blinks even when you put the device in the charge, its hard bricked and will be fixed just with opening the phone and relive it with test point ...
maybe this thread will help you:

If it's brick, no prob, let's begin
Requirements:
The latest Flash Tools version, the latest FTF file of your phone, or any FTF file you want
Plug your phone to AC charger for about one or two minutes, and if you see red LED, now your phone is OK
1) If your phone has more than 50 percent charges, you can unplug it
2) If it has less 50 percent, let it charge for about an hour or more till it reaches 70 percent
So, no matter the first way or second, after you unplug it, now you can now connect your phone via USB and flash it
If you do everything correctly and if nothing goes wrong, after flashing, you can use your phone without any problem
If you couldn't do it, inform me to help you more

Look at the micro sd slot. Is there a red stripe? Or white?
If red, it's a water damage

It happened exactly the same with mine. I was on stock rom, and went to the swimming pool with it. But the stripe is white.
I cannot turn it on and only get the red light blinking when is plugged into the charger...

Try the hard brick fix (if you have warranty send to Sony instead). I doubt it'll do anything because it seems by your decription the hardware is damaged physically, but its worth a shot.

Drain your battery completely
By Pressing and holding volume up and power button for 15 second, no vibration dont worry just hold it for 15 seconds and forget your phone for 1-2 days
Get working charger and usb cable check it then connect charger to phone there should be red light
Leave your phone for 3-4 hours
Now disconnect your phone from charger
Again check usb cable and drivers in pc
Open flashtool and get stock ftf ready for flashing
Once the dialog box appears with phone's animation
press and hold just volume down button and connect your phone with pc and immediately Release volume down button as soon as dialogue box disappears
Then disconnect phone when instructed in flashtool and wait for 4-5 minutes
Now try to turn on the phone.
Main thing is to have patience
This should work as i have my phone in same hardbricked state twice and this brought life in my phone back..!

This fixed mine

I hope, your solution works for me too. I ordered a battery and waiting for delivering it. If it won't work, I'll write here to help someone like us who wants to order a new battery.
Edit:
After battery changing, the phone worked. I don't know why, but it had been locked and rebooted repeatedly. Then I resetted to the factory settings. After that, it has been started to run well.
