I'm using sony xperia V and after flashing a cyanogenmod rom which installed perfectly, until I select reboot and the screen
turns black and no matter which button combination or whatsoever I can't boot up.
The only things that happen is:
if unplugged, pressing the power button will vibrate the phone and green LED flash for a second
if plugged into computer the green LED flashes for a long time. Holding the volume+ button before plugging in will flash a blue LED light for some time
Both plugged and unplugged, the screen shows nothing at all, which means can't enter recovery mode, safe mode or download mode.
Is there anyway I can solve this? Or I can only buy a new phone or act dumb at the sony store.
Thanks in advance and sorry for any trouble
[Edit]I finally found a way to solve this problem after hours of frustration. Thanks to this amazing website which I couldn't post it here due to being a new member, which I could say it's from a website named androidgadgetmatic, really turned a completely useless brick into a perfectly working phone again. The only problem left (which happened before bricked) is that my phone couldn't read or even find SD card, any help in this area guys?
Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks

Good day !
Hello everyone
Please help me
I have a Sony Xperia Z3 Dual D6633 with Android 4.4.4
Firmware is D6633_23.0.F.1.74_CE
I tried to install TWRP on my phone using this tutorial
https://forum.xda-developers.com/z3/development/root-stock-kernel-twrp-v01-test-28-09-t2889794?__utma=248941774.950623471.1412017766.1412017766.1412017766.1&__utmb=248941774.1.10.1412017766&__utmc=248941774&__utmx=-&__utmz=248941774.1412017766.1.1.utmcsr=l.facebook.com%7Cutmccn=(referral)%7Cutmcmd=referral%7Cutmcct=/lsr.php&__utmv=-&__utmk=228295838
Since the links in the thread are down it was hard for me to get the bootZ3dualmonxtest01.img file
But after an hour of googleing finally I got it from another Android forum https://mdforum.ru/showthread.php?t=16534
Then, as mentioned in the tutorial I went into bootloader / fastboot mode and entered following command
fastboot flash boot bootZ3dualmonxtest01.img
But it didn't work. Now my phone is bricked. It's powered off and I can't turn it on again
It doesn't respond to anything
Pressing Powerbutton - Nothing
Pressing Power + Volume Up/Down - Nothing
Hold Volume down and connect to PC - Nothing
Connect to 230V Adapter for charging - Nothing
ADB doesn't recognize the phone
Flashtool responds "Device disconnected"
So I can't flash back stock ROM
Please help me out. What went wrong? How can I fix it? Is it repairable or is my phone hard bricked?
Thank you for your answers
Edit:
After several hours of googleing and trying I found a solution that worked for me
Great thanks to StuartjG who posted the steps in this thread

My Z3 would not power up and no charge LED when cable plugged in. Finally found this solution on Sonymobile support website which fixed my phone!
To force the device to restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") until the device has emitted three vibrations, and then release the OFF button. The device turns off automatically.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
If a forced restart procedure as described above doesn't succeed in turning on your device, you should try another kind of forced restart - the 2-minute restart procedure.
To force a 2-minute restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") for 120 seconds (ignoring any vibrations), and then release the OFF button.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
I had to hold the 'off' button for about 60 seconds before the phone vibrated and sprung into life - phew!

In my case there were no vibrations. I just held the button down for 120sec and it worked. Then I was able to flash back stock ROM
Hi,
I was fixing a hard brick using this thread for MSM tool.
https://forum.xda-developers.com/oneplus-7-pro/help/help-device-corrupt-trusted-boot-t3946658
I couldn't see the Qualcomm QD loader appear on my device manager but went ahead and started the tool. It looked like nothing was happening so I unplugged my phone and suddenly reaslised there was a progress bar on the MSM tool.
Now when I try and switch on my phone or hold down the vulume up and down buttons I get this message flashing up after a brief boot screen
<!>
Upgrade download failed!!!
Please check your download flow is right.
accompanied with a message on my PC that the usb device isn't functioning.
Update: I just tried it again and Qualcomm QD appeared on device manager briefly before the problem returned.
Advice?!?!?!?!?!?!?!?!?!?!?
OK issue resolved. Think my USB port is on the blink. Still, haven't seen that error message mentioned anywhere so quite interesting...
Thanks for sharing. Did you get the phone back to a working state?
I'm having this issue as well, did you manage to get this fixed?
same problem here
any solutions?
For any other forlorn souls who come across this thread, I was experiencing essentially the same bug I think, I'm not really sure what happened (I got up to get a drink), but when I came back to my computer my OnePlus 7 Pro was stuck in a terrifying boot loop while plugged in where all I would see, all in yellow was:
<!>
Upgrade download failed!!!
Please check your download flow is right.
That would be visible for a second or so and then the phone would power cycle and display the OnePlus splash screen for less than a second then back to the yellow error message. I could not boot into recovery, fastboot, or standard.
SOLUTION:
Plugged phone into PC via USB, held down the Volume Up and Volume Down buttons and waited for it to power cycle itself. Screen stayed off, but it showed up in Device Manager under ports, and I was able to start the MsmDownloadTool and flash a new system image.
So its odd but I get this message briefly as the phone boots up, but the phone works otherwise. Do you know how to do get rid of it because running the MSM tool has not fixed the message.
same here. anyone?

You save my phone, thank you so much, this works to me.
Sir, I have a Redmi Note 4 device, two years old. I'm having some hardware issues with it like power button doesn't work anymore, one of the speakers is not working.
The phone has switched off couple of times, but I managed to turn it on with pressing a specific part of the power button. This time, it's not working.
I surfed on the Internet and found a solution by using FASTBOOT mode. I did as instructed -
I pressed the volume down button and plugged the USB cable of my phone to my PC.
The fast boot mode showed up and now, whatever i try, it' s stuck there.
Please sir, need you help ASAP.
Regards,
A noob.
