phone boots up but doesn't respond - Sony Xperia Z Ultra

The phone boots up but only the power and volume buttons work. can't swipe or do anything on screen. Have to push the red button to turn it off. It was working fine and just started doing this. I can get it to recovery but twrp doesn't respond at all either. Seems like the digitizer function shut off. Any fixes? Ive tried the sony flash tool but can't get it working right although I flashed with it before. I can get it into bootloader mode -- haven't yet tried reflashing the rom using the command line.

Recovery mode? PLease Help

Hey guys,
A few months ago I rooted my phone and put the Cyanogen Mod rom in it.
Everything was working perfectly..until recently.
My touchscreen is not responding...and the touch pad is also not working.
The phone boots fine but I can't click on anything because the touchscreen is not working.
Anyways, I decided to reflash the rom thinking its a software issue rather than hardware.
But, How do I get back into recovery again?
Usually I would just use Rom Manager to boot to recovery but I can't access this app because I can't navigate to it using my touchscreen or touchpad.
I read that its Vol down plus holding power. I did that but phone continues to just boot normally. Am i doing something wrong.
Please answer.....Thanks...
it is vol down plus power, but you got the order reversed. hold vol down, then press power. once that's done, select recovery.
I tried your method as well (Volume down + Power) but no luck. I think my volume key doesn't work or something.....any suggestions?
I made some progress
Instead of volume down + power (which didn't work) I used back button + power which got me into recovery.
Only problem now is that I need to select recovery. I cant seem to do that because my volume down button doesnt respond when I press it.
Is there any other way to go down in this menu screen....the keyboard is not working at this screen and also it says this message: touch screen - failed
please help
Perhaps android commander can get you to recovery. google android commander and install it on your computer, turn your phone normally and plug it into the computer after its done. Run android commander and select your app, i do recall an option for reboot to recovery.
Yes, thanks for the tip. Android commander is great.
I tried using it to get to recovery. It wouldnt work though. I get the red triangle.
Then I tried flashing a rom using android commander. It worked....the rom installed fine.
Problem now, though, is my touch panel, volume keys, and track pad don't work. They didnt work even before I reflashed this rom.
In Hboot it says touch screen: failed.
Im not sure whats going on.
Is there any way to fix my touch screen. Am i missing something?

This is a hardware issue. So no matter what you flash this is going to continue since its not software related

[Q] Stuck on splashscreen and hard-resert dosen't work?

Hey, I've just installed the ViperDNA rom and tought I would try it out. I've installed everything correctly with TWRP and Aroma showed me everything was installed fine.
Now I am booting my phone and I've noticed it was stuck for over 7 minutes in splash screen, so I tought okay I will do a hard-reset. I've pressed over the home button for a minute and the it didn't restart, the panel was flashing but it didn't restart. I've tried to click on other buttons and all but it didn't work, I've connected it to the PC and tried to find it with ADB and it showed the device is not connected. The battery is full and it's in the splash screen still, how could I possibly restart the phone?
- ADB dosen't find the phone
- Tried to check if suddenly the phone is stuck in fastboot (sometimes happend with my old phones, unknown how)
- Tried to press the home button for over 1 minute to restart when it should be 10 seconds.
Anyone knows how to do something? I am hoping my battery will run out somehow like this, but untill then. I need some suggestions.
Hard reset is holding power button for 10secs not home.

[Q] [HELP!] GT - I9100 bricked

Well I was undervolting and underclocking my i9100 for a few months and it would suffer from freezes and stuff like that nothing much as I would be able to perform a hard reset and reboot with my phone completely working everytime that happens. However today, I just locked my phone after taking a picture and I could not unlock it after that. I pressed the power button and home button but the screen would not turn on. So i just took out the battery and tried booting the phone. It was stuck in a bootloop where the boot animation would just keep on playing. So i force shutdown it and booted it into recovery. I had CWM 6.0.4.6 installed and when i booted into recovery, it gave me the message it cannot mount something and cannot load last kmsg and blah. I took no notice and tried to format cache. During this point, the recovery hanged and i force shutdown my phone again. After which, I could never turn on my phone again. No splash screen no nothing. I think it is bricked. And yea btw my usb port is not working anymore and it can only be used for charging. And i was running cm11 infected. Can you all please help me thanks!

Yep i cannot even boot into anything no splash screen no nothing pressed the power button for like so long i even removed the battery for 2 hours and popped it back in not working
Try this - take out battery,then press and hold volume down+home+power and put battery back without releasing buttons.This may get you into a download mode where you can flash stock jb via odin.

Solution for (full)bricked M4 (tested E2303)

Hello brickers and others.
Maybe i found THE solution for a hard bricked M4.
I was messing up my phone after flashing roms over each other and wiping several things several times.
So i hard bricked my phone i think because this is what the phone did :
In the first period the phone was starting but shows only the Sony logo for about 30 seconds and then the phone restarted automatically, and so on. That means i was in a boot loop.
I didn't came in to TWRP recovery mode. That did not working anymore
Pressing volume down button and connect to pc for Flashmode did not working too. I came into Flashmode and my pc whas finding the M4 but after 20 seconds or so the phone was rebooting by himself. Thus Flashmode was unuseable.
The volume up button for Fastboot mode was working very well.
Only, my point is i can't flash a firmware via Fastboot. I don't have enough experience that way, if it is possible at all. I don't know.
Okay, i was stuck at that point.
After flashing as a dumbass some kernels via Fastboot mode i came in the second period, a hard brick i think.
The only thing what my phone did now was going on for a few seconds (showing Sony logo) after a long press on the power button, and then it turns off.
TWRP recovery was also that time not working.
My phone was not showing the led when he turns on that few seconds.. I didn't came in Fastboot or Flash mode anymore (no led showing up). Nothing was working anymore except that the phone turns on for a few seconds after a long press on the power button.
THE SOLUTION
I hope for every M4 users i found the solution for this brick. I don't know if it is mentioned yet somewhere. I didn't find it. It feels like a secret combination but it worked for my M4 E2303.
"Press the volume up & volume down button at the same time and keep it pressed. Then press the power button and keep all these 3 buttons pressed, LONG pressed, TILL the following vibrating code has COMPLETED!!!"
Code: rrrrr rrr rrr rrr
Now you can release the buttons and Fastboot & Flash mode should work fine now. You can use Flashtool now to flash a STOCK firmware (tft file) via Flashmode.
After completing your phone is repaired.
Succes.

noooob with nabi2 screwed it up...

hi I hope this is posted correctly... I have a nabi 2 running kitkat that was rooted with kingo root and no twrp, everything stock besides that... I deleted something I shouldn't have and when I restarted the tablet it booted fine until it got to the home screen. as of now I have no lock screen to swipe and no home screen. The home button and back button still show and also make a click noise. so I figure to do a factory reboot and everything would be fine... well I was wrong... it still boots but still no home screen.... at times the background will flash and the time and battery will pop up.
So I downloaded nabilabs thinking that would be able to help me and I believe it will but as I found out when I did a factory reset it turned off usb debugging and will not connect now. so with out screen controls how do I turn usb debugging mode on? is there a line I can send to it to connect? thanks for the help in advanced..
I did search around and found a bunch of great software and roms for it but I really haven't found a similar issue or realized that I found something close to my issue.
Do you have a photo? That would make it easier to know what you’re describing
Your firmware may be corrupted.
I put the link to a new ROM here. If you click click the hyperlink it will be at the top of the screen. Use Fastboot to flash that.
Put Fastboot Protocol on by holding down both the volume buttons and the power button, then when the letters on the top left (held in landscape) of the screen pop up, click the volume - (down) button and then click the volume + (up) button. Your computer will now recognize the device in Fastboot. Then you can flash the ROM.
See if that helps.
