Can you change the bootloader? - Hard reset no longer working, Any insight?

So I have been trying to overcome the issue of power + vol up (held for 10, 15 seconds\ and more) not working on my device. No matter how long I hold the two it just won't reset the device.
At first I figured it could be kernel as that is the lowest code that I've knowingly changed.
Changing to back to stock kernel did not fix it.
I thought it could be any sort of thing so I redownloaded the NL 434 firmware and then also universal generic 434 firmware and flashed back to completely stock with flash tool, doing all wipes and excluding nothing.
Neither of those firmwares fixed the issue, the hard reset function still won't work on my device.
Additional info:
Both buttons function fine individually and can see no obvious reason to suspect it's a hardware fault (though see that it is feasible, just less likely).
I can confirm that it was working initially.
I have an unlocked boot loader.
The last time I can remember it functioning was prior to boot loader unlocking - the first thing I flashed after unlock was cm10.1 and I got stuck in sideload mode with no hard reset to get me out lol
Otherwise the device is fully functional. For the time being I am back on KA07 xperia revolution rom, with advanced stock kernel (cwm) from DooMLoRD.
If anyone has any suggestions or insight it would be greatly appreciated if you'd drop a comment :good:
EDIT:
I've restored back to 350 with EMMA, but to no avail . It did however tell me that my boot version is : 1264-2309 S1_Boot_Lagan_1.0_2
Is there anyway to change the bootloader :S

After getting home I tried re-locking the bootloader which didn't work.
really starting to wonder if I should be taking it back in as hardware fault.. wonder how that will go since I unlocked the BL

If anyone would be so kind as to do a quick test for me, would you please be able to go into service mode (open dialer type *#*#7378423#*#*) then go into service tests and select the buttons and switches one (I think that's what it's called )
When you hold down the volume up or down button, is it registering as 1 press, or several, continuous presses?
Cheers

Not entirely sure what you are asking, keyboard and switch, volume up only shows as volume up and volume down as just volume down, regardless if you hold it down or press it over and over again, or if you just press it once. Not sure if I am an idiot, but I couldn't work out how to test the keyboard from there.Although one interesting part is that is states it is not a test for the softkeys, but tests them fine

Yeah that was the menu I meant.. couldn't remember lol. Ok so when I would hold down volume up it plays a repetitive tone and the text on screen states "vol up", then "vol up vol up" for the longer I hold it (and the beep/sound keeps replaying... confusing sounding I know
When you hold the volume up botton down, does it just beep once and display vol up (exactly like if you were to press it once and release)?
Basically if I were to press it once, the phone would make a sound and the screen would display "vol up"
If I hold it down however it will register as a new press and the "vol up vol up" texts keeps refreshing as-though it was a new key press.
Also thank you very much for checking it out :victory:

Yep exactly as you say here.
Volume up once shows just volume up beeps once, twice shows volume up twice and beeps twice . Holding it down beeps over and over again and shows volume up twice.
Pressing volume down once from here (volume up volume up) shows volume up volume down, press volume down once more now shows volume down twice.
Hope this helps

Yeah it helps that I can probably assume that my buttons work fine.. I was thinking maybe they weren't registering as long pressed or something but apparently not this is really frustrating. Especially when an app freezes and I just have to sit there indefinitely till it comes back online or the battery goes flat
And I have no idea if it's something I did or something with the phone.
All I know for sure is that brand new it did work as I hard reset a couple times. Then I unlocked the bootloader and have no memory of it working since then... It makes no sense to me why completely returning to stock and relocking the bootloader has no effect though.

Yeah, I could imagine. You will have to find a cool fast battery draining game to help you along .
Not sure that it would be related to you unlocking the boot loader, otherwise I am sure quite a few would have mentioned that before now.
Do you even get the first vibrate confirmation? Have you tested the vibrate from the same service test menu?

That what I'm thinking - can I seriously be the only one having this problem. And why the hell does everything else work perfectly fine lol.
And no I don't get any sort of response (vibration or anything). Normally it just results in the volume turns up then the screen locks or display just times out but even after a minute of holding pwr + vol up nothing happens and the phone is simply in sleep mode. Otherwise vibration works fine.. currently I'm restoring the backup I made of the out of the box stock rom.. that's pretty much the absolute last thing I can think of that might do anything. Trouble is I don't remember if I made the backup before or after unlocking the bootloader.. can't remember if I flashed a custom kernel to get CWM or installed it otherwise...

I would recommend re unlocking the bootloader, the problem is a kernel level driver or hardware but it is definitely around that level.
Did you have any problems, or errors when you first unlocked the bootloader? Maybe Doomlord could give you some of his incredible knowledge on the subject

Sorry but are you trying to reboot the phone from a frozen state?

No the phone is 100% operational outside of the hard reset not working. It is just when I get stuck in a app that freezes or when CWM recovery tricks out and freezes I have to leave the phone for ages till either it a)unfreezes after an hour or so somehow, or b) the battery dies and it shuts off after a couple or more hours.
When your phone is out of action every second day simply cause you can't turn it off it gets pretty annoying haha. If it had a removeable battery I could easily live with it and just rip the batt out no dice.

Already tried that but no luck.
Stranger still is that I've began to notice that in flash mode the LED briefly flick green once then turns off when entering flash mode. Flash mode is still active, it just appears as though the phone is off :/

(Q) Screen stops responding?

So across all roms including stock and cm based my touch screen will randomly stop working and i am forced to reboot the phone via the little pin hole method unless i am missing a hardware key reset combo? Anyway the screen turns on and everything looks like it works except the fact that none of my touches register at all? How do i fix this issue? Its not a big deal when i am at home with a pin or pencil but sometimes i am away from home and cant reset it...

Well, just hold down on/off button and power up button for few seconds. You will feel a vibration. It will restart
Hold it a bit more and it will switch off with three vibrations.
I guess you should get your phone checked. It seems to me hardware problem. it could be a bug too but chances are slim!
Secondly, try clearing dalvik and cache but I am afraid it wouldnt be of help!

Volume up and power button does nothing for me at all... Also would sony even look at it if im running a custom rom with an unlocked bootloader? Doesnt that null the warranty>?

Just go on stock rom n relock your bootloader. Sony might ask and make sure you say nothing about rooting, custom rom or anything. Just it's not working well should be the answer.
Secondly, try volume down +power for few seconds when phone is on. Even try volume up+down +power for few seconds.
Make sure you hold these buttons simultaneously.

managed to temp fix it going into settings then sound and changing volume panel style to none on pacman rom,unfortunatly sound still goes to full

Volume key defective

Hi, I wanted to ask if in your p9 the volume button wobbles

Yes, compared to the power button the volume button is a little loose but I don't think it's defective...

Thanks, I thought it was a problem only of my device :good:
The volume when you press the keys lowers normal or suddenly? I noticed this flaw, sometimes lowers and raises normally at other times just press and it also lowers too.

no one else noticed this bug?

Mine wobbles too, but power is more ridged.

So it is a problem of all!
And sometimes when you press the volume buttons it rises and falls abruptly?

I've tested five different devices in five different stores and all of them had nearly the same loose volume button. So I think it's a general "problem". This is not a good build quality for this price.
Abrupt volume rising generally appears when the phone was set to mute or vibration by the quick settings shortcut. As soon as you hit the volume button the volume jumps back to the level it was before the phone was muted.

My volume button doesn't wobble.

And it happens this problem? Of course I do not keep the buttons pressed. https://m.youtube.com/watch?feature=youtu.be&v=neGc3-aMjss

Well, this looks definitely like a bug! That's not normal and has nothing to do with the feature I mentioned before.
Did someone with the loose volume key try to replace his phone on warranty?
Is this really a defect or do we have to live with it?

Do you have the silver or the grey version? Maybe it's related to this...

I have not asked for a replacement. I have the gray version, why?

The problem creates youtube, if you end app and delete data of the app the volume returns to work properly ...

Is normal
Mine is P9 gold and has also loose volume key . It is a normal behavior

I also have the loose volume button. (mine is EVA-L19)
I asked the store about the issue and they showed me a couple of devices. All of them have had the same button. Don't worry about it. My previous Honor 7 had the same issue.

Updated to Android P, now phone won't boot unless ...

I recently updated my Mi A2 via OTA update by using Express VPN to connect to India. Everything was fine until I powered off my device. It would not turn back on (no boot animation or anything).
However, I then proceeded to plug in the charging cable. After doing so, my screen lit up and I was able to get my phone to boot.
Now the problem remains that every time I turn my device off, it won't boot unless I plug it in to a power source.
Please, anyone experienced this? Is there a way to fix it? Would an update further down the line fix an issue like this?
Please, I can use my phone normally when it's on but this thing with the not being able to boot is just bugging the freak out of me.

I've had a problem like this before, hold power only gives a vibration and doesn't boot, just keep holding the power button

It freaggin worked

I honestly didn't expect this to work but it's as you say. My phone would just vibrate and nothing more.
Following your instructions, I held the power button longger than usual and it finally booted. You sir are a legend. Thank you !!
But it would be awesome to know why this happens though. Was it due to something in the pie update? and will I need to be holding down the power button considerably longger (around 5-6 seconds) moving forward. Or will it boot like normal now?
Again, before anything else. Thank you

In India, I received notification that I got pie update, I downloaded, installation process was done but when my device rebooted there was only blank screen and when I press power button, it vibrates, but after pressing buttons and volume button. . . My device successfully booted into 8.1.0 lol I don't know what happened, anyone know how fix it?

I'm not sure why this happens, I don't know if it started right when I updated or when I made some modifications to system, but I solved it by flashing the update again in recovery
