Hello everyone,
I am trying to understand what is the key fault of my HTC Desire. I since have changed to a HTC One X, due the fact that my Desire has lost both full phone networking and sound capabilities. The rest of the device works like a charm, currently with Paranoid's Jelly Bean rom, even on heavy load.
The phone has gone through three accidental falls (bad luck serie), that required me to change the amoled screen only three times up to now. The original digitizer is still like new. After the last fall, it started to develop some sound issues before the two ones I expose here. It started with the music only in one of the headset speakers thing (by compressing the left part of the phone, I could get back music in both ears).
Rapidly, I discovered my Desire could no longer catch the phone network, and so could no longer be used for calls, SMS or mobile Internet.
Additionally, no sound comes out from anywhere : front speaker, back loud speaker, headphone. The microphone appears muted as well. The volume settings are all at maximum, including using a more complete audio manager app from the Market. Headset detection plug/unplug works fine.
So apart from the other functionalities that all work (screen, digitizer, vibrator, Wi-Fi, Bluetooth, SDCard , Sim card (detected and activated), USB, heavy load from benchmarks and games, volume buttons, camera, etc...), the phone is rendered useless by not being able to catch phone networks and not produce any kind of sound.
I have replaced some parts of the phone since this issue has begun : the upper board with flex cable (that was tired) and the loud speaker (was tired as well). It has not solved these issues (it only solved appearing detection issues due to the tired flex cable and failing volume buttons).
I now use the Z-device test app to try to diagnose the issue. I am not sure I understand them, but they may give hints :
- He is detects the SIM card well and displays its information.
- He detects the phone as gsm type, but is unable to display the gsm cell id (blank space). He finds the device id (long number) and the software version (00).
- Data state is therefore set to disconnected.
- Multemedia chip is undetected (blank space)
- ALSA version is undetected (blank space)
- SCO for off-call use is set to true
- Microphone is set to muted
- Speaker phone and wired headset are, whatever happens, always set to false.
This is it. I haven't got further yet. I try to situate the possible hardware fault, since full wipe and reflash has not solved the issue. I only have those suspects :
- What is called the Wi-Fi cable, that is damaged (the thin cable can come out easily from one of it's metal end, while it is clipped properly).
- What is called the antenna cover (that looks like yet another plastic piece, with two metal pins on the left side), the cover being slighly cracked on the right side but still completely screwable.
- One of the motherboard's IC chips or component for an unknown reason.
The phone is in good state and works well now, aside of these two key features. It does not look like it has fallen down once, a shame. What is your opinion on this? Do you have ideas or suspicions?
I thank you by advance.
About your sound issues (speakers, headphone), sounds like your amplifier died.

Probably. I doubt the isseu would come from the so called Wi-Fi cable as it may not both transport sound and act as an Antenna.
I therefore need to see if it is possible to replace the amplifier chipset. Might require precision soldering though.
Still idea concerning the gsm fault...

Hi there!
Looking at the "connectors" page, it seems possible to me, to tinker a cable/plug for external line in; for example for a microphone - or, which I intend to do, for a guitar pickup, so the tuner software I bought (which works very well) will also do it's job fine under "real" circumstances (before a gig, when the surrounding always is pretty noisy).
But there are some questions:
- which way to go, with a large or with a headphone connector?
- for the second, there will the internal speaker be off?
- for the first, there's also just the possibility to switch off both, internal mic *and* speaker? Or will line in also work, if CAR_ON# is not on +6V? But then the internal mic will be on and catching all noise, too?
- what means "Audio needs to be capacitively coupled in" on that page?
- which other pins have to be connected somehow, to somewhere?
- ah, and if going with the (easier to realize?) headphone connector - where to get one?
sorry for silly questions,
thanks,
Manfred J.W.
Hi everyone, hope someone can point me in the right direction. Flashed OmniROM on an HTC desire (bravo) and it's working great. Only problem is when making a call, no sound comes out of the earpiece. If I put it on speaker phone it's fine, and apparently when it's not on speakerphone the mic works fine, people can hear me on the other end, but I can't hear a thing. Suspect the radio is the problem here so need advice on which radio to use (especially for internet use too) and how to install it. I have Ext4 bootloader installed too. This is my interim phone after my Samsung Galaxy S2 died completely (will not power up since it died during normal operation), which looks like it would need a JTAG burn to fix, right after I successfully replace the USB board. Anyway, any help appreciated. Thank you.
Can it not be that the earpiece is simply broken?
Does it work for instance over Wi-Fi calling e.g.Skype? Can you get any sound to come out of it?
Was it working before you flashed the ROM? If you backup and flash different ROM or better yet back to stock, does it work?
Just want to do logic tests before concluding it's a radio issue, which I'm not sure it is.
So confirm above before playing about with radios as they carry a but more risk. To flash radios, you need to be S-OFF, and use fastboot commands. Check the md5 sum of the radio.img before flashing because a bad radio flash= proper brick.
There is no recommended radio, though latest one should generally be better. Depends on individual signal quality so different people get different results
Good point. Got around to thinking the same myself. Found a replacement speaker on ebay (local seller) which I ordered (it's cheap). Meanwhile searching the market for a speaker tester.
Desire adr6300 running cooldroid
old thread, but I have a similar but slightly different issue and it doesn't appear to be the radio
Cant hear anyone on call, they can hear me
Works on earphone - can hear caller no probs, they can hear me ok
If i switch to speakerphone during the seemingly silent call, as soon as some noise (voice or otherwise) is picked up from other end, then the speakers start screeching - quickly getting to max volume. Goes silent again if speakerphone option switched off.
Hadn't flashed anything when it started to my knowledge, but had been installing various things. Nothing significant to my recall.
Tried re flashing cooldroid after clearing caches - same
tried installing mildwild - same
reflashed radio (it is the latest and been on ages) - same
Cleared everything except sd data but including ext partition and reflashed coildroid - same.
Oh - audio tracks play fine :/
Help.
Slight update on this.
After trying different roms and reflashing the later radio:
Flashed an older radio on it that i had on it before - same.
Radio_32.56.00.32U_5.17.05.23
Radio_32.56.00.32U_5.17.05.08
Seems like mic (others hear me) ok when used normal, but I cant hear them
but some sort of feedback squeal when i put it on speaker voice does come through quietly along with the screeching (no its not the missus), the screeching only starts as soon as some noise is picked up through sending phone
When earphones connected (hence mic and speaker on phone disconnected) - all fine.
So possibly some sort of short in the ear speaker unless someone who knows the hardware better than me can suggest something else
(Do these have noise cancelling mic which is disabled when earphones are connected? - must look that up when I have some time again)
Update
it does seem to be simply a failed ear speaker
Update
Got around to replacing the ear speaker (less than £2 delivered from ebay)
SORTED
dead easy job - 10 minutes to replace and all ok now.
No sound through ear speaker now sorted
This is for ear phone - but shows how easy it is
Speaker is just under the top board - no cable just prongs and stickied in place.

Over the past week I have had a few issues with audio apps on my phone - Google Music, Audioboom, Soundcloud etc.
When my headphones are plugged in and audio is playing, tracks randomly pause or skip to the next one in the queue, and sometimes the volume starts changing by itself. I am also getting frequent reboots when playing audio with headphones as well.
Just wondering if anyone else has had this issue with the Mi Max? I am on the latest XenonHD rom. Could be faulty headphones perhaps?
Thanks in advance for any advice on this one
Have you recently replaced screen or just opened rear battery cover?
Had same symptoms, volume up-down, viper on-off, tracks pausing and so on.
My problem was: replaced recently screen with frame. Appeared that the frame was not 100% match, earphone jack was in the phone under pressure. Had to open the battery cover for about half a millimeter, stucked in a piece of platic.
Everything works now.
Ordered new frame.

I haven't changed the screen or anything...
I'm hoping the issue lies with my headphones (as they are not too expensive) or some software issue I can fix by flashing the rom again - a hardware issue like you had may be more difficult to solve!
I'll try some other headphones, and if that fails I may just reflash the rom. If that fails it will seem to indicate a hardware problem....

It turns out it was my headphones - bought another pair and everything is back to normal!
Ok, so I had been using my old android phone connected to bluetooth to my 2017 Honda civic to stream music. I am finding that like my office, the more LCD displays the better. I like being able to switch Pandora stations on one screen and change a setting on a GPS tracking device on another while I am driving (less button pushes) so I used my main phone for a GPS and my second older phone over my hotspot to stream. Then I saw theses android rear view mirrors and I thought they would be even better (one more screen) So I bought this Weigav android mirror to see how it would function (hopefully like an android phone). Here is what I have found so far:
The Good:
Connects to my hotspot well
Connects to my Honda head unit over bluetooth for music streaming (this was a bonus as no ads for these android head units specifically said they will connect to bluetooth for streaming, they only say for phone calls)
Pandora and Sirius XM works for streaming
The Bad:
Internal Battery does not seem to last overnight so the system has to re-boot every morning and sometimes I lose the default settings for bluetooth and wifi ON
Navigation is slow to respond. Also Waze seems to have display issues.
UI does not have as many options to control things as I would like
Sometimes it will say "insert SD card" when there is always one in. I was thinking it says this when the SD card is full, but I thought it was supposed to just re-write older video files when it is recording from the front and rear cameras. Sometimes an SD reformat helps, sometimes not.
The Ugly:
It has built in lane departure and front vehicle warning that works too well. It is too sensitive, so it says a lot of false positives. Which wouldn't be so bad except for the fact that you can't adjust the sensitivity or the worst part, YOU CANNOT TURN THESE WARNINGS OFF. This means I get a thousand interruptions over my music I am streaming that I can't turn off. If it had a separate volume control for these, I would just turn it all the way down, but there is only one volume control.
So the question I have is does anyone else have experience with this or any similar device? I know a lot of these issues could be solved in software and I looked everywhere for other ROMs but I haven't found any. I think maybe the next step may be to root it and perhaps delete those sound files for the warnings I can't turn off. If anyone has messed around with this stuff, I would appreciate any advice. Thanks!
I recently installed a Xtrons PQS90MTVL head unit in a skoda superb. I have a couple of questions on how to get it to work correctly when navigating.
1) It seems that you can set the navigation sounds to be a percentage of the radio volume but cannot set it to play at a given volume regardless. The problem is that the radio seems to be constantly on and there is no way to turn it off. The 'on/off' button simply mutes the radio - and the navigation sounds.
Often I am in an area where I cannot pick up a decent radio signal on the programme I want and just get static. In these situations I want to turn the radio off but still hear navigation sounds. I don't want to listen to loud static just so I can have the nav sounds play at a percentage of that static. Is there a way to turn the radio off but still get navigation sounds? (a workaround I have found is to play a media file instead of the radio and then pause playback. The nav sounds are then still a percentage of the - non existent - playback volume. However this should not be necessary)
2) It also seems that a Internet connection is needed for any navigation. even google maps won't do a search without it as it says I am offline. (is this true?)
I have bought the 4G wifi dongle but have a question about its use. Does the HU connect to the dongle, as far as data is concerned, via the USB socket that comes out of the back of the unit or is that socket simply powering the dongle and the HUI is actually connecting to it over wifi using the dongle as a hotspot? If so then I don't have to use the wired usb socket from the unit (which I suspect is underpowered) and can plug the dongle into an ordinary 2A USB socket that I have in the car, positioning the dongle near the roof for a better signal
Incidentally I did try using Android Auto with my phone using wired connection. That seems sort of OK but is not very reliable. Often when starting the car it hangs at the 'connected' screen, or even at the 'trying to connect' screen, although other times it seems OK
3) There is a small socket on the left hand side of the HU that looks like a slot for a small memory card or a sim card. It is labelled 'GPS'. What is that socket used for? it is not mentioned in the manual as far as I can see. - The manual is generally a bit hand waving though, excitedly telling you what you can do but not how to do it.
(I did try the xtrons forum but not only are the last posts there around January 2022 but there seems to be no way to register for it. Hence posting here)
Is it MTCx post system info including mcu version.
Mtcb is long retired

All I know is the model is Xtrons PQS90MTVL so maybe its MTVL (whatever that is) I'm afraid I don't know what mcu means so cannot offer any version for it. Its possible I have posted this in the wrong section and have rep[osted in 'Android Head-Units'. If that is the right place and this is the wrong place, please can you delete this post
