Volume slider stopped working:( - 8125, K-JAM, P4300, MDA Vario General

Hello all,
I've just done the stylus fix and now the volume slider has stopped working and i don't know why. It doesn't spring back to centre anymore or do anything onscreen or adjust the volume.
I have the service manual but it only says to disconnect keyboard fpc cable, but not how to do so, and the picture is unclear.
I need to do this to remove the main board and look at the volume slider properly. but, I'm a bit scared of breaking it further.
Please, if you know how to help out, or have had this or a similar problem let me know what to do.
Thanks in advance

Front buttons no longer work

This is very odd but the start, "ok", green phone, and red phone buttons on the bottom-front of my phone no longer work at all. Oddly the front "wheel" works though. Has anyone had this issue before that knows how to solve this? Is there somewhere where these buttons are set in the registry by chance? Any help is GREATLY appreciated for this is a very annoying problem.

Registry Help - volume keys on diamond

My Diamond is about to go in the bin!!!
If anyone knows how to edit the registry to "switch off" the volume keys on the Diamond then please, please, please help me.
The volume screen is permanently flashing on my screen, and seems to be stuck on the up button which means I can't use the phone. it's not a hardware issue as the buttons aren't stuck or won't work, it's from a bad flash (according to HTC!) - i've tried stock roms/MTTY etc but the problem still persists from one rom to another.
Any registry experts willing to help
Not sure how you can achieve this if the volume is always on top but if you install AEbutton you can unmap the volume buttons
thanks for the reply i'll give it a try
What happens if you leave out volume control? I guess MS volume control would prolly pop up then ?

I can almost 100% sure tell you that it's hardware there is a sensor underneath the button that is probable stuck. because if it wasn't then a rom flash would have fixed it. there is a spray don't know what it's called in
English but something like contact cleaner it cleans electric parts for dust

Thanks for the replies everyone, AE button seems to have fixed it, although i'm not 100% sure that it's gone yet, as it could stop for a while and start again.
HTC did say it was a hardware fault caused by installing hard spl/custom rom (although I only left Hard spl when I sent it back..by mistake ) and wanted to charge me £230.
i'll try the spray cleaner anyway I don't think it will do any harm.
Thanks again for all the replies, at least it's semi-useable again...

Is it possible to repair the Device?
Sorry for the bad quality of the picture. He only sent me this one.
Thanks in advance!
Hi
you have to Hardreset you device in you original state,to do that,you have to presse the volume button (Plus & minus) both together at the same time,than the red reset button beside your SDcard,at first presse both volume button,and stay on it, than a short presse on the red reset button, look on the screen of you phone, after a couple a secound you will get the 3Colored screen if you see the 3colored screen take the pressure from the volume buttons,after that it is everything explaind on the screen to go back to you original ROM, it takes sometimes more than one tray to get to the colored screen,berause the pressure have to be exact on both, plus and minus volume.
Thank you very much. I will tell my friend to do that. If other people read this and think that its a good idea to do it this way maybe you can tell me. So I can be sure I dont want to tell him something wrong.
Btw this portal is awesome!!

[Q] UMI Zero issues - speaker and touch buttons.

Hi all,
since I am new in this forum I would appreciate if I am in the wrong section to raise my issues, please let me know and I will accordingly move my post. Thanks.
Following issues I face with my 2 month old UMI Zero.
1. can not make regular phone calls via speaker. my partner can listen, myself cannot hear a word. fact headset icon shows in the very top menue line, speaking via headset works fine but does not make life easy.
serveral factory resets done, updates etc. nothing worked.
2. yesterday, the next issues occured out of nothing. my touch buttons do not operate anymore at all. no function behind except the blue lights. Need to reboot if I would like to switch apps/functions.
Anyone who can help me to solve my problem or experienced same issue(s).
Thank you.
Best

Same issue with buttons with my umi zero
My buttons stopped working as well all at once, considered as contact problem until one day they returned to respond unexpectedly.
After working fine for a while stopped responding once again.
Thinking it's might be software issue, I've installed a new rom material V 3.0 lollipop inspired 4.4 kitkat provided by umi Root joy tool. It didn't help, however, regardless to update the buttons now are lightened but not stable responsive therfore still useless.
For now used this post to enable soft keys: search Google for "enable-soft-keys-navigation-bar-android-phone"
Another free app which I found useful is called My home Button, can be downloaded from play store.
Hopefully a solution will be found soon
The only solution is to dissasemble the smartphone and connect properly the hardware components, you can dissassemble your phone with an hot air gun
Same issue and possible solution
Come on! Are u kidding?
My buttons stopped working yesterday but with a reboot everything was fine again. Until now. No signal from the buttons, light nor fucntion. I'll try flashing it and, if not, i will have to dissasemble and check the hardware.
If this doesn't work I'm thinking about downloading an xposed module that allows you to remap the phisycal buttons. I'll try remapping home, back and settings buttons into the power and volume ones. Let's see if it works.
First of all sorry for my bad english ( I'm french). For the problem with your touch bouton you can also use gravity box ! With this app you can enable the navigation bar and you gonna have touch bouton like the nexus phones. If you don't know how to do that you can ask me question in a next post.
Dear All,
Just want o let you know that after being hesitant for so long, I finally disassembled my Umi Zero and guess what? The back camera connector was not connected, and the touch button + speaker connector at the bottom was also not connected! I just connected them back, put the battery back, and touch buttons + mic were working fine. Tested with voice recorder, playing audio, and also few calls.
Disappointed though by the component assembly....most of the screws were very lose and one even came out without unscrewing. Also, the screws are of different sizes, so please please please take note where each screw goes (What I did is get an A4 paper, made a sketch of he phone outline, and placed the screws on each area where I removed them from).
Note : Most likely you will break the back glass cover so you might as well place an order on Aliexpress before you disassemble it. It is possible to remove it without breaking with lots of extra caution though.
No sound and no soft keys
I had the same problem with my daughters Umi Zero.
I found a work round for the buttons:
-temporarily install an app which emulates the keys so you can navigate. eg Handy Soft Keys from the Playstore
-enable in settings/accessibility
-reboot
-need to be rooted
-install file manager, eg ES file explorer
-in ES tools, activate Root Explorer
-navigate to local/device/system/build.prop
-drop to end, leave a couple of lines space then edit by adding: qemu.hw.mainkeys=0
-save and reboot
You have soft keys
Uninstall emulator app
Backup etc before you start
Haven't fixed the sound yet: nothing from the speaker, phone and headphone jack doesn't work.
Bluetooth does work.
