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

Thought I would share my experience with this PITA tablet.
Just spent a few days scratching my head trying to factory reset a Lexibook Barbie MFC190BBEN model Android tablet.
It belongs to a 7 year old girl who put a password lock on it for some reason then forgot her password (much to her Mum's annoyance).
The Lexibook support site suggests going into settings and selecting factory reset.
Obviously this cannot be done as the tablet is locked so their next suggestion is to send it back for 'out of warranty' repair!
Some serious googling got me as far as recovery mode (sort of) which involves the reset button being pressed with a paperclip whilst pressing the power button and volume up at the same time whilst connected to a pc via usb.
This gets you a blank tablet screen, adb access but no fastboot and the adb is very limited and stops responding to simple commands.
It uses a Rockchip processor but most of the drivers do not give a stable connection.
After lots of trying to get stable connections so I can push a custom recovery (or get anything at all to talk to the damn tablet) I found that if you disonnect the usb cable and reset the tablet with the reset button you need to hold BOTH volume buttons then press the power button for a couple of seconds..keep holding the volume buttons and you should get the Android robot with a red exclamation mark.
From here I reconnected to the pc and adb could now see a device in recovery mode but with a serial of 0123456789ABCDEF
Still no joy with any adb commands....
Just a few reboots to blank screen again with no adb.
So I reset again and held the two volume buttons to get back to the Android with red exclamation mark again.
Some more googling found a different type of Rockchip based tablet that suggested NOW pressing the power button and volume up quickly..........
Well it turns out this tablet DOES have its own recovery!!!
No amount of googling told me this!!
So after days of messing about with drivers and button presses it turns out it is a simple task to reset from recovery.
You use the volume keys to choose from the minimal options in the recovery menu and use power to select.
Due to the amount of googling I did with no answers that worked (or even came close to an answer) I thought I would share this in the hope it would save someone else from pulling their hair out and keep their child happy!
[emoji1]
you're legend, mate ... I've been trying to put google services and youtube on it for ages. Now it seems it can be done!
No mater how i press the buttons the android robot never appears just the normal start screen please describe the key pressing combination again
Press the reset button with a paperclip whilst you hold BOTH volume buttons then press the power button for a couple of seconds.
Keep holding the volume buttons and you should get the Android robot with a red exclamation mark.
NOW press the power button and volume up quickly..
This should get you into 'recovery'
Thank you. I ll give it a go. Do you know who makes the barbie tablet? I would like to get inttouch with them if it doesn't work.
I have a Lg G Pro 2. Few days back it got bricked by its own( a crazy fact). That time it was showing QHSUSB_BULK. I figured it out as 9006. Took the phone to a local service shop. Today I got it back and found that nothing had happened to the phone, except worse. Now it is not detected by PC, only green light blinks for some time if tried to power on. And then everything is black and cold as death.
I think it have been flashed with wrong ROM. Anybody here can guide me with the test points of Lg G Pro 2 (D838 F350) ? So that I can force it to QHSUSB_BULK ? Or any step by step advice to get it up ?
I am in real need of assistance, and thanks in advance for any sort of help. Best Regards.
I would like to mention that the phone indicator blinks for sometime if I try to power it on, as it does on boot, but nothing else is there. No recognition by PC, no presence in Device Manager. Blinks for sometime, stops, again starts blinking... and this goes on at regular short intervals. The area around the camera gets warm after sometime. Everything loops till I pull off battery.
Now, am I missing something ? Is the problem not as deadly as I am thinking ? Is it soft bricked ?
Hi, I not sure how it got bricked I never brick LG device.
Normally if anything happen we try pull battery out and put it back in, try then to turn the phone on.
Have you try connect to to pc with USB cable, one end of USB connnect to pc and other end connect to the phone. Then try press Power + Volume Up or Power + Volume down, this is to try to get into phone download mode. If you can get into download mode you can flash the kdz file to make it useable again.
Or without the USB cable we want to get to factory reset mode by use hardware method try press:
- Power + Volume Up or Power + Volume down
- If you see LG logo come up release the buttons you press above 1-2 second
- Press again Power + Volume Up or Power + Volume down
- Until it show and ask to use volume up/down button to select choice, say yes
Caution factory reset will delete all data on the phone and reset it as when you bought it new.
- Again it will ask for factory reset, use Volume up/down to choose and select yes for factory reset
turn on the phone and when light is blink press volume up or down button for some time and see if it it is detected as usbhulq?
I have a Galaxy S6 with a faulty power button.
I took it to a Samsung Repair Centre.
After "diagnosing" the problem (which I had to pay for), I was told that the faulty power button was due to "liquid damage" (it has never been in water everything else works fine).
They said it would cost £180 to repair and would require they replace the whole motherboard.
I refused as I cannot afford that repair and would rather consult a third party shop or purchase a brand new phone.
Unfortunately, the state I received the phone back in unusable.
Before the phone was sent in, it was at least in a state where I could at least use it (providing I kept it charged and did not power it off).
Now its just stuck in a recovery mode => restart => no command (boot loop), and I cannot select an option from the recovery mode screen because the power button does not work.
I planned to flash the stock firmware to try in order to get it out of this loop, and I can get it to boot to download mode as the volume buttons and home button work fine.
However, now when I'm at the cyan warning screen it prompts me for volume up to continue.
I press volume up and nothing happens. I know that these buttons work for a fact as in recovery mode I can navigate up and down.
Any ideas whats going on? or what I should try next?
Videos of the issue
(Tinfoil theory: Did they purposefully lock down download mode after inspecting it?)
If you have time, continuously keep pressing volume up and power until it gets you into Odin. Best of luck.
We're on slightly different devices, but mine has the same defect. The power button failed overnight, it worked to start the device but afterwards, the power button became stuck in the pressed state and I couldn't lock the device (not mechanically, it is still clicky). The volume down button still worked (I don't have to hold power to force a restart because it's stuck in the pressed state), I wanted to take a look at the knox status in the download mode, it didn't respond to volume up, this means that it's dependent on not having power pressed. I somehow got the restart confirmation to show with the power button, twice, so it's not completely defective. The volume down button cycled through being stuck and non-clicky, working normally, and being stuck while being mostly clicky, like the power button, though it doesn't seem to be stuck in the pressed state. It's likely because I kept pushing Volume Down for hours in a terminal emulator. Today, it takes 5 mins of torturing Volume Down to restart the device. Eventually, it might fail completely. This device seems to be able to ignore volume up / down if those buttons are stuck and work almost completely normally.
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

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 Everyone,
Phone decided to randomly turn off (at around 80% charge) and now won't boot. Have tried all the basic TS guides.
have tried:
-Charging - no on-screen displays
-Holding power button for various intervals
-Button combinations (Power + vol up....etc)
Connecting to PC gives me an indication that it has detected a USB connection, then consistently after ~40s I get the disconnect notification sound. Then off for 20s and the the cycle repeats.
I'm assuming it is stuck in bootloop for some reason but still nothing from the screen.
Phone hasn't been dropped, rooted, is running stock ROM etc...
any ideas?
Assuming the bootloop isn't caused by hardware failure then you can try forcing your phone into its Recovery mode by holding down the power button and volume down button simultaneously. From here, you may be able to roll your phone back or restore a previous backup. However, this often results in data loss, which isn't ideal, so you might have to weigh up your options.
If this doesn't work, you'll need to enter your smartphone's Safe Mode. When your phone is booting, and you see the manufacturer's name appear, press and hold the volume down button to put your device into Safe Mode. Here, you can follow prompts to hopefully remove whatever program, app, or software updates forced your phone into a bootloop.

It won't boot at all, the screen doesn't turn on. But surely something like this doesn't just randomly fail
My recommendation: take phone to authorized service center and let them try to fix it.
