[Nexus 4 Q&A, Help & Troubleshooting] Fidelio_o:
I have an issue with my nexus 4 where the only audio that comes out through the speakers are notifications/alarm. All audio works just fine when headphones are plugged in.....any suggestions? Work fine until a couple minutes ago.

Headphones-All sounds work.

No Headphones- only notifications and Alarm work.
[Nexus 4 Q&A, Help & Troubleshooting] Fidelio_o:
Bump.
[Nexus 4 Q&A, Help & Troubleshooting] gotzaDroid:
Dumb suggestion, but clear out all recent apps. I had an issue like yours (but no sound through head phones either) and I found that the stupid chive app was goofing up the sound output. When I clear that app out of recents, I got my sound back. Not saying that's your issue, but worth a try.
[Nexus 4 Q&A, Help & Troubleshooting] Fidelio_o:
Try it. Got soundabout app from app store and set it to speaker and it worked fine. So I'm assuming phone is stuck in headphone mode.

Hi again,

I arranged all my widgets as I wanted at the very start, when had just installed ARHD 7, but now after a few hours, I cannot drop any widgets on the homescreen, "Personalize" force closes!

I cleared htc sense's data, as well as re-flashed the rom smartflash enabled; still the same. :(

[HTC Amaze 4G] PCLiteratesJax:
So, I bought this HTC Amaze on Craigslist with a broken digitizer for $80 which wasn't a bad deal at all. Everything is working on it, I already rooted it, SIM Unlocked it etc. Today the parts came in to replace the screen. While taking it apart, the Power Button Flex Cable ripped :( I found a replacement part on eBay and already ordered it. Now, it's not one of those clamp connectors, that would be too easy, it looks like one of those iPod ones. What is the best way to adhere it to the motherboard itself? I took two screenshots of an Amaze motherboard with attached power button flex cable so you can see how it should be attached and a second picture with the part I ordered. Any help is greatly appreciated !!
[HTC Amaze 4G] PCLiteratesJax:
Here is another picture from a listing on eBay. I am almost certain that it simply needs to be glued on there, so the 4 contacts of the on/off button flex cable have contact with the contacts on the motherboard itself.

Anyone? Nobody knows? I am getting desperate here :(
[HTC Amaze 4G] kazzxtrismus:
It may be bonded but not with anything you are used to using.. OEM manufacturers use special glue For electronics..

This stuff is no joke.. Regular glues will degrade the board and proximate solder joints dramatically and within a few days

I would bring it to a repair shop..

I'm sur you don't want to buy a $25 tiny bottle of glue to use 2 drops

Henkel is the new owners of loctite (6 years).. They make the most prominent brand.. You then will need to properly clean the board and seal the connection.. A proper shop should fix this real cheap if you bring it disassembled and ready

Sig:

What do you mean I can't say that??!!.. It's the fkin Internet!
[HTC Amaze 4G] PCLiteratesJax:
kazzxtrismus, first of all, thank you very much for replying :) I believe you are talking about a conductive glue like "CircuitWriter", correct? I am willing to pay the $ 25 at RadioShack, as long as I can get this phone working again :) I just contacted HTC and asked them about the "CircuitWriter" conductive glue before I go out and spend the money on it :) I am still mad at myself that I wasn't more careful while taking the phone apart :( Hopefully they'll get back to me soon :) I went to two different cell phone repair shops yesterday and asked them how to do it properly and they had no idea. It's very frustrating LOL I know that it's not soldered which is great, micro-soldering really sucks unless you have 20/20 vision (which I don't have) LOL
[HTC Amaze 4G] kazzxtrismus:
I used to sell board level components and chemistry to oem's..

I would not recommend anything from radio shack.. For this type of application..

Their are a few flex circuit manufacturers that may offer to fix it on a "personal favour level"

But that's a stretch

Call any local supplier..

Ask to PICKUP a sample of the glue.. Do your research on how to use .. And Offer them the $20 for the sample

Usually something like this uses Conductive paste like a solder pad.. Basically soldering with glue... Ugh!

I'd want to see the "as broken" pic.. Sometimes you can fix with fine wire or another flex and solder the gold traces together with "elite" grade solder and a high end manufacturers grade soldering station ($400).. No.. A hako won't do it

Weller/cooper wm2 and fine tips

[HTC Amaze 4G] PCLiteratesJax:
ok, I took two pictures of my currently non-functional Amaze, the first one is of the motherboard connector and the second one is of the broken power button flex cable. I don't think that my broken power button cable can be salvaged. It definitely kicked the bucket when I disassembled the phone. The third picture is of the replacement part that I ordered.
[HTC Amaze 4G] kazzxtrismus:
Ok.. So the special glue is probably around the fingers not in between.. It's probably clamped in place for curing and the holes look like they are for alignment..

If it feels like caulking, it may be.. But NOT regular caulking.. Regular caulking has ammonia in it.. That's like flesh eating disease for electronics!..

If you try this yourself metering the glue will be tough... Just enough for the bead to be taller than the gap.. But not so tall as to ooze into the fingers...

Then "clamping" is also gonna need to be accurate even with the alignment pin holes.. You don't want anything less than perfection as the fingers need to stay aligned while curing.. Tape is a good idea for holing alignment, but, parallelism needs to be maintained too....

Good luck big guy... It is possible but I don't envy your task

[HTC Amaze 4G] PCLiteratesJax:
I really appreciate all the help and input from you !! This is definitely an undertaking that I am not looking forward to :) I think this whole power button flex cable setup was poorly designed by HTC, a regular clamp connector would have been just fine LOL Besides this little annoyance, it's an awesome phone though :)

What if the part comes with the adhesive already on it, that is possible too, right? In that case, I would just stick it on there and hope for the best? I remember that when I separated the old, broken power button flex cable from the motherboard, it was STUCK on there, I mean, I had to take it off with some force, that is why the metal pins are bent (and one actually fell off).

I am a gal btw, one of few who are into this kind of stuff ;) I own a small computer repair and smartphone repair business here in Jacksonville FL :)
[HTC Amaze 4G] kazzxtrismus:
Awesomeness!!

Nothing better than a lady in the house!..

I highly doubt the glue comes with..

Yes htc pooched the design here.. But it does make for more room on the board and keeps the connection sealed.. Still.. Stupid tho..

If the fingers were glued / bonded (which I doubt) their are "crazy glue" like agents available too.. I'd call Henkel or look at the website first tho.

Your comment about it being stuck /glued really good tell me it may be more of an encapsulent.. I'd have to smell it.. If it smells like an automotive body shop then probably is an encapsulent used a little differently... Encapsulates are usually 2 part.. Like epoxy

Sig:

What do you mean I can't say that??!!.. It's the fkin Internet!

---------- Post added at 07:34 PM ---------- Previous post was at 07:31 PM ----------

I just used my computer to take a better look at the pics.. It's glued between the fingers..

Is the glue hard?

Sig:

What do you mean I can't say that??!!.. It's the fkin Internet!
[HTC Amaze 4G] PCLiteratesJax:
Girl Power !! hehe ;) I can't really tell if the glue is hard or not, there is no glue on the broken power button flex cable at all. It looks like the 4 metal connectors on the motherboard itself are a little raised actually, that might make this whole thing a little easier, hopefully. If the replacement part doesn't have any adhesive already on it, I am almost thinking that if I use 3M 2mm double sided tape around the new power button flex cable, that that could be sufficient for the contacts on the motherboard and on the power button flex cable to have contact. Plus, the front facing camera flex cable is right on top of the power button flex cable, so that should be pushing the whole thing down as well (I guess that was HTC's intention when they came up with this design).

I am really hoping that the replacement part already has the adhesive on it :fingers-crossed:.

PS: I love your signature by the way ;)
[HTC Amaze 4G] kazzxtrismus:
Try poking at the glue with a dental pick.. with the experience of a tech you'll know if it's hard or glassy or rubbery.. You'll probably also know if the top layer is soft and inside is hard..

Don't try to remove the glue.

A hard under soft = encapsulent (usually)

a full hard = tamper proof encapsulent.. cry!

Rubbery = caulking

Sig:

What do you mean I can't say that??!!.. It's the fkin Internet!
[HTC Amaze 4G] PCLiteratesJax:
Good thing we have dental picks from a laptop repair :) Well, it feels like it's smooth on top, but that could be from the broken part itself, like it's residue or a coating or so. It also looks like the connectors on the motherboard don't have anything on them. That's a good thing, right?
[HTC Amaze 4G] kazzxtrismus:
I'm suspecting that is an encapsulent..

You may be able to use a pin file to make room for new glue.. Don't take all of it off.. Just make space so the new flex cable fingers will make good contact..

This is only a good idea when you have the new cable.. Wait till it comes in and see what you have to work with..

I highly doubt it'll come with glue.

There shouldn't be anything on those fingers... Ever.. Each finger and it's glue cannot touch each other unless the glue is non conductive..

You will need to find non conductive electronics grade adhesive..

There are different kinds of conductivity.

Conductive

Esd (electro static dissipative)

Capacitative

Insulating... This is what you want..

Sig:

What do you mean I can't say that??!!.. It's the fkin Internet!
[HTC Amaze 4G] PCLiteratesJax:
I just checked the tracking information from eBay and the part will be here tomorrow :) I'll take a picture of it once I have it in hand and post it here and let you know if it comes with adhesive already on there :) Thank you so much for all your help and input !! :)
[HTC Amaze 4G] kazzxtrismus:
You are very welcome..

Just remember that "placement" is going to be the hard part..

The fingers will need to be WELL aligned and COMPLETELY clean of the adhesive.

THEN it needs to stay that way until the glue has cured.. Please also remember that too much glue will cause the glue to squish between the fingers keeping the flex away /up & off the main contacts

Good luck

I am undertaking doing this my self. I will be using some graphite conductive glue. I'll let you know how things go.
[HTC Amaze 4G] PCLiteratesJax:
So I assume that you are in the same jam I am in? Did you order the part yet? My replacement power button flex cable will arrive here in the mail today. From what kazzxtrismus said, and I agree with him, we only need glue AROUND the connector fingers, not on the fingers themselves. Therefore, conductive glue might not be the right stuff to use in our case. I am really hoping that the replacement part comes with adhesive already applied and it's a "stick and be done with it" undertaking :) I'll let you know how it goes :)

UPDATE: The part came in the mail and of course - there is no glue on it (go figure, my luck !!).

I attempted to attach the replacement part with just a little bit of double sided tape above and below the area with the "fingers" and I put a very thin foam piece on top to press the whole thing down, making sure that the "fingers" are directly on the contacts of the motherboard. Well, that didn't work. I called a local cell phone repair shop (CPR - Cell Phone Repair) and talked to a guy who specializes in HTC phones, especially the HTC Amaze 4G which he can disassemble in about 2 minutes, so he said. I am going to take my phone there tomorrow and have it fixed. He said he'd take pictures and he'd let me know what he did to get it to work again and I'll be more than happy to share my newly aquired knowledge with all of you. I really don't want to do it the wrong way and then make things worse than they already are and having to buy another part and wait more time, still not knowing the correct way to fix this.

UPDATE: I drove to CPR this morning and talked to the lead technician there. Bad news. He said he has tried to fix these type of connectors about 100 times and NEVER got them to work again. He said that HTC uses a cold press (that costs about $100K) and a special chemical to adhere/attach the power button flex cables :( I am not ready to give up yet though. I *could* use the phone as my secondary phone by being always on and turning it on through adb. Not good enough for me :) I'll try to remove any possible residue on the connectors on the motherboard itself and try again. I really don't have anything to lose but everything to gain and I am NOT a quitter either :)
[HTC Amaze 4G] dwind:
Q] Broken Power Flex Cable - how to attach replacement part?

Well no gold cigar yet. The graphite glue is not controllable enough. I can't place it and leave it. So with the fingers being close together; it is highly possible that you would have bleed over. So what I did was take the some finger nail polish and just brush the areas away from the fingers. Well the phone powers on, but continues to power on and off..without a need for the flex button. So I will start over and try to set it better.
[HTC Amaze 4G] Shadow Samurai:
I remember taking apart my hd2 to replace the screen because my brother dropped it on a tile floor. I thought it would be any easy task since I replaced the screen on a g2 I got for $50 just fine. When I took the thing apart I broke the actual ribbon cable connector for the LCD and found a replacement on amazon. I then took it to multiple different repair shops and nobody said they could fix it.

I then ended up buying another hd2 with a cracked screen but this time was very careful when I took it apart. Later, when I flashed android nand to it I found out that the bastard gave me an hd2 with a defective motherboard, causing the phone to freeze every time I used it.

I eventually just ended up selling it for $100 on craigslist along with the parts from the other hd2 since I was getting a new phone soon anyway and had a g2 to live with.

Moral of the story... Don't let your clumsy brother touch your precious tech. (He is only two years younger than me too)

I still bug him about it too because I really loved that phone.

You're lucky only a ribbon cable broke!!

[HTC Amaze 4G] kazzxtrismus:
A cold press is no different than a stack of quarters to hold it down while the glue cures...

In a mass production environment it's very handy... Measuring out the glue is the hard part..

You need a non conductive glue that hardens quickly.. Like fiber glass resin... Its called. Encapsulent..

It goes on thick like tooth paste.. Then hardens (usually 15 minutes - ish)

But as you both know it holds quite well..

You may be able to get a small syringe of electronics grade caulking.. Which should do the job of it dries not so rubbery.. It may take about an hour to cure though....

As I said before aligning the fingers is going to suck.. You need to think about all 3 directions.. The alignment holes will help with 2

Sig:

What do you mean I can't say that??!!.. It's the fkin Internet!
[HTC Amaze 4G] PCLiteratesJax:
I wish it was "only" a ribbon cable :( It's a flex cable that most likely only HTC can fix because none of the local repair shops can afford that cold press machine with the chemical that HTC uses to fuse the contacts together :( The lead tech I talked to said that HTC is designing their phones like that so they can rake in all the money because people HAVE to send their broken phones in to them and they are also putting local repair shops out of business :( So far, have been using the broken Amaze as my secondary phone, I turned it on via adb :)

I still have my daughter's old HD2 that has Android installed on it here if you are interested ;)
[HTC Amaze 4G] Woz2000:
Any luck with this?

My friend brought his cousin's phone to me for repair, he replaced the digitizer but broke the power button cable in process.

I'm thinking if this is near impossible to glue back, I will use wire wrap wire and solder jumpers between the cable and motherboard. Case looks like there is room for this.
[HTC Amaze 4G] PCLiteratesJax:
I believe that could work but the "fingers" and connectors on the motherboard itself are so tiny, it would definitely be micro soldering. Please let us know if it works :)
[HTC Amaze 4G] Woz2000:
I take it from your response that you had no luck.

I have soldered on finer pitch before so it is definitely doable. As long as the trace is not low quality it should okay. Key is not to use too much heat, clean the pads and use flux. I will probably attempt this tomorrow and will try to take pics for you.

Since it is a simple 1 position on off switch, there should only be two wires. I looked at the cable and the middle two are shorted, both pads to the sides of the middle should be ground and may already be making contact using the large square pad that is making a spring contact on the case, so this may only need 1 wire going to the middle two pads... fairly easy task.

Problem is I don't know if he killed the other parts doing the original repair, so I don't know if I am wasting my time! I will let you know after my attempt!
[HTC Amaze 4G] Woz2000:
Fixed

Here it is...

Fine soldering, took me about 20 minutes.

If anyone wants to attempt this, you must be very experienced with fine soldering, have a good soldering iron (temp. controllable preferred), good eyesight, steady hands. Use low temperature to solder the wires on the switch contacts, increase the temperature to solder on the phone. You may want to do it in reverse of what I did (solder on phone first with higher temperature, then on switch with lower temperature). Put shipping tape over the finished work, fold but do NOT crease.

The wire I used is a 30 gauge wire wrap wire. You need to solder two wires. Solder a wire to the outside of either of the outside contacts, then solder the second wire to one of the two middle pins (use the one farther from the outside wire you just soldered).
[HTC Amaze 4G] PCLiteratesJax:
YOU ARE DA MAN !!!!!!!!!!!! Wow, congratulations !! So, only 2 wires need to be soldered, interesting :) I have a friend who is an electronic engineer at our local "hacker space" JaxHax, I'll show him your pictures and have him do the work, I am sure that he has all the tools needed for this :) You were a HUGE help, my friend !!! Thank you !!!!!!!! I wish I could give you a million THANKS :) I'll give you a virtual hug instead {{{{{{{{{{{{{{{{{{{{ Woz2000 }}}}}}}}}}}}}}}}
[HTC Amaze 4G] Woz2000:
That was a big squeeze! :)

You're very welcome. If your friend has enough experience soldering then it should be fairly easy for him. On the other hand, if he only solders a couple of times a year, it could be problematic. Tell him... if he is having trouble, stop before the motherboard traces are lifted, it becomes another nightmare when the gold contacts break off.

Let me know what happens.
[HTC Amaze 4G] PCLiteratesJax:
I will definitely keep you posted :) It looks like this week is busy for me, I'll see if he can do it this weekend :) And thank you again, my friend !!

Did you ever fix it?

Hi there, read up on your post and I'm in the same jam....fixed my digitizer and screen and broke the power flex cable when initially took the phone apart...i probably took the phone apart like 50 times...lol....but nothing works...but can't power it on....my phone is HTC amaze (ruby)....

Was wondering if you were ever successful in fixing the power flex cable?

Thank you, Tiffany
[HTC Amaze 4G] PCLiteratesJax:
Tiffany,

Woz2000 was successful in fixing his and he posted step by step instructions on how to do it :) I haven't had a chance to work on mine yet, we have a computer repair business and things have been really busy this week. You can use adb to turn your Amaze on too if your phone is rooted, that's how I got mine running for the past week or so :) You have to have USB debugging turned on for that though.
[HTC Amaze 4G] Woz2000:
Tiffany, stop pulling the phone apart. Those flexible cables are very delicate. If you are pushing on the middle of the cable to insert them, there is a good chance your new digitizer cable is already broken. The digitizer cable is folded over so when you are pushing it in, it bends the little traces in the cable, they could break in as few as 5 insertions. The phone is not going to turn on by itself if the power button is broken.

If your phone is rooted and you have used adb with it on your computer, you can try turning it on with "adb reboot" to check if your new parts are working. I can fix the power button for you for a reasonable fee, but if the other parts are broken also...that's another story!
[HTC Amaze 4G] wildfire460:
You are a genius!! power flex cable no match for micro soldering beginner chick! lol

Hey!! just wanted to tell you THANK YOU!!! You are awesome!!! Thanks to your creativity and geniousness my phone is working!!! I've only soldered once in a my life but figured it was worth a shot! So I did...used 50mm wire and patience and voila!! My HTC Amaze 4G ruby turned on for the 1st time in 2 weeks!!

One problem...well not really an issue...cause I'm just happy it turned on....when you pop the battery in..the phone turns on automatically and the power button will not turn off the phone or put the phone to sleep. Like I said no big deal.

I was wondering if you had the same issue....I soldered the 2nd and 4th just like you did....any ideas? lol

I don't think i'll take it apart to add more connections lol! but just curious to know why its acting this way.

Again million thank you's!

Tiffany =D
