[Solved][hack][Thor] unresponsive volume buttons - Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot

Hi everyone,
NOTE: volume buttons fix I mention below is superseded, see my reply to this post.
In the following post I was unable to enter recovery or fastboot.
[SOLVED][WCIF] patch0.xml etc for bricked HDX 7 thor? Have QDLoader 9008 access
Fortunately a cable and flashing software solved the problem but the underlying problem turned out to be Hardware (at least).
Only after I got a working OS back on this tablet did I determine that the volume buttons didn't work at all.
But I found by stretching the rubberized case off of the right edge of the screen I presumably compressed the audio subsystem hardware connections in just the right way and this got the headphone jack and the volume buttons to start working again.
With the rubberized case pulled away from the edge I had to cut away the headphone jack area so headphone plug will still fit. Please see better solution in my reply below.

Update:
It turns out on another site ("i fix it") that discusses various handheld devices' hardware someone else identified a better solution that doesn't require physically modifying the tablet.
I found that solution during a search after stretching/distorting the case as described in the post above stopped working.
Basically the soft material this tablet is made out of warps easily and applying a stiff back solved the problem for mine. I used a piece of thin laminated wood available local home improvement stores. I taped that on as seen in the pictures. Before taping the board on, I taped a small cable tie to the back of the case to add a little pressure point approximately an inch in from the top and side edges of the case nearest the headphone jack. That area appears to be where the connection lies that's required to keep the headphone jack and volume controls working.

[Q] Microphone Hardware Tech Question

I fix all kinds of smartphones for a living. I convinced my buddy to get an LTEvo but his microphone is not working properly. I figured I could just open it up and replace the microphone with a new one. However, I am not sure as to where exactly it is located. I noticed the mic hole on the bottom of the phone and I assume the mic is located on the large flex cable that extends downward toward the bottom of the phone. Would this be accurate? I have included a link to a parts vendor in order to verify that this is indeed the correct part that I need in order to fix his issue.
Large Flex Cable - http://www.globaldirectparts.com/HTC-EVO-4G-LTE-Flex-Cable-Ribbon-p/htc748935.htm#
Close-up of what appears to be the microphone on the ribbon cable - http://www.globaldirectparts.com/PhotoDetails.asp?ShowDesc=N&PhotoNumber=5&ProductCode=HTC748935
While I can't help you completely, there are two mics. One on the top, one on the bottom. I installed a new screen so I disassembled the phone a few times getting everything working correctly. I don't remember if the mic was on the flex cable or if it was part of the boards located on the top and bottom of the phone.
Good luck though.
Edit: found my old screen. I think you're good with those flex cables. Just make sure you get them for both the top and bottom mics.

poor Wi-Fi reception signal

purchased 2 of those devices specifically to use for tethering, need a device with wm6.5 and unfortunately can't use it since it can't pick up any signal from my routers or iphone or bluetooth tethering.
i can have this thing sitting on top of wifi ap and still get no signal. does anyone have any sort of a fix for it? thanks !
tried updating to RUU_Leo_1_5_TMOUS_3.14.531.1_Radio_15.42.50.11U_2.15.50.14_LEO_1.5_Ship but it error out
my rom is 3.14.405.2

Would assume they have been opened for repair & not assembled correctly.
Usual issue for wifi/BT is coax cable not clipped into brass connectors correctly.
ideally you need pull back cover off & check the cables that rundown side near volume button.
also check all spring fingers on mainboard that contact on arial tabs of rear housing are present & correct position to contact.
Many people snap the spring fingers off the mainboard with rough handling & don't clip the coax cables in properly.
Also worth noting you have a power setting for wifi so that needs setting to max to help maximise range.
Use over 20 HD'2 in my work enviroment & wifi is perfectly good enough & they make a great wifi router/tetherer with wmwifirouter
thanks !
to pull back cover i need to use heatgun? i used setting for max power w/o any result
To remove rear cover you don't use heatgun.
Pull battery, sim & memory card, remove all screws.
Use a plastic pry tool to loosen edges top & sides
*do not push any tools in around volume button area*
Main trick is to start at top as top has 2 good clips either side of speaker grill
once top showing signs of release work round side without volume key & once this shows signs of coming off it very easy.
Do not use metal tools, screwdriver as cause horrendous damage
Take care as many things are easily broken with poor handling.
Cover clips back very easily.

[Q] Ear Speaker & some Hardware Questions

hi guys i need some hardware infos.
my short story: i got a hox+ stuck in a boot loop it was sure that it was not a software problem so i replaced the battery, that didnt fix the problem after some testing i found out that the problem comes from the power button cable, i pulled the connection off and the bootloop was gone, i repluged it and the bootloop returned. so i thought maybe the screws are fixed to strong, after several plugs & replugs and my decision to not put the top screw back inside and dont fix the other screws so strong, for a little bit more flexibility between the mainboard and the chase the problem went away and seems fixed.
But now a other problem appears, my top ear speakers stopped working, sometimes they work and sometimes not
so my questions are:
1. has the power button flex cable anything todo with the function of the top ear speakers?
2. is it possible the speaker didnt connect probably because the top screw is missing?
3. is this w*w.ebay.com/itm/New-HTC-One-X-S720e-G23-Power-On-Off-Button-Flex-Cable-/251492842139?pt=US_Cell_Phone_Replacement_Parts_Tools&hash=item3a8e243a9b compatible with the hox+ (international)?
4. is this w*w.ebay.com/itm/HTC-One-X-Ear-Speaker-w-Adhesive-Replacement-Repair-Part-OEM-/271110152540 the same as this w*w.ebay.com/itm/HTC-One-X-Plus-Ear-Speaker-w-Adhesive-Replacement-Repair-Part-OEM-/281124922511 or are they different?
sorry for my bad english, i hope u can understand me anyway

speaker and led not working

hi all, i have a spring samsung s3, it recently had some water damage but not full blown submerged in water. it still turns on and all buttons and functions work fine. however the speaker seems to be blown, i can hear a hiss noise from it and when i do the service menu quick test, no sounds comes out nor does the LED notification light up. pushing volume up and down buttons still work.
anyone have any idea if it may be the audio chip damaged or some sort of flex cable? i'm hoping its a part I can order and replace myself. I have opened up the phone and know how to take pieces/cables a part (aside from chips on the motherboard... may have to pass on that)
