mic-spk loopback Blackview Bv-9600pro - General Topics

Hello first things first I'm totally new to this forum and I'm posting my question cause I searched the internet for weeks now and I simply can't find a solution.
The long story befor is.... I got a blackview bv9600pro for free and wanted to put lineage os (GSI) onto it (cause the blackview software is packed full of bloatware) this worked quite well except for the sound so I thought.... maybe just try the never version los 18.1... but this completly destroyed the phone into a softbrick (I think it destroyed the boot.img). So to get it back running I needed to format&flash it with the sp-flashtool. But there might come in my problem... I Have no Backup !!! So I got the original IMG from the blackview Forum and used it.
So now I'm on the original blackview software.... needet to flash the imei back... working fine.... but now to the real Problem... The mic simply does not work anymore. Or at least thats what I thought. After a while of testing around I tested a mic test app and my mic seems to work fine in direct mode but not to work at all in comunication mode and basically all apps except for memo apps use comunication mode. So I dug in a little deeper and found that Blackview has its on "diagnostics" built in (I think in its recovery.img)..... so I did run that and everything has run well except it shows me my mic error "mic-spk loopback failed". So I dug in even deeper and if I'm not mistaken its used to loopback the mic cause many android devices have multiple mics but blackview cheaped out and only built in one. So my real and Final question is - does anyone have any idea how to fix my mic?
Thanks in Advance BIzZmarCk

Sorry you didn't get any reply. If you contact blackview's support, you may get a free phone out of that, just saying.

Can't turn on the bluetooth

hello,
unfortunately i cannot turn on the bluetooth from comm manager, it turns on and after 1 second is off again.
any solution for this problem?
thanks.
I have had this problem before and unfortunately am having it again. Only solution I have ever found for this is a hard reset and then reinstalling all your apps. If you try to restore from a backup from Sprite Backup, for instance, the problem remains. This would lead me to believe that it's a setting or a registry issue somewhere but I haven't been able to locate exactly what would be causing it and don't know enough about programming in WM to write something to figure it out.
Not a great answer but there it is.

Hi, I have a Uk version of the touch cruise and I have the same problem. I just did a hard reset but the problem remains. Turning bluetooth on is impossible. It just try's to turn it on and shuts it off immediately.
Maybe it has something to do with GPRS? I am always connected to the internet. I tried to disconnect but then bluetooth still doesn't work. Can anyone help? Thnx!
No one has a clue?
I had this prob with bluetooth and wifi following the use of wmwifirouter- after hard reset and no wmwifi all goes well...
On a French SFR rom
any other idea?
Same problem... beginning to wish I'd gone all Apple and bought an iPhone. Anyway.... To trun it on, I had to go to Comm Manager>Settings>Bluetooth>Mode>Turn on Bluetooth. That worked despite the Comm Manager still showing Bluetooth as "off".
It only connects 1/2 the time to my headset or handsfree in the car
Otherwise, the phone crashes only once a day! Great! Thanks!
ok, great to see more people having the same problem but i hope that someone has a sollution...
When I try to turn bluetooth on in the communications settings i get a message saying there is a hardware error! :S
Ohw btw, I'm not using any router programs or other and my WIFI works fine.
has anybody of you having this problem tried to change to another rom?
if yes? did this worked?
any news on this?
No news, I don't want to try for a different rom because i don't think it will change anything. It just seems like its a faulty device which is a real shame. I've already contacted the place where i bought it and see if i can get a new one.
I also have problems with my microphone during calls, photo camera does often not work and the touchpad reacts very slowly to my touches. Very annoying!!!!
Yup, am returning mine to HTC aswell. Not even sure I want it back. WiFi stopped working too, and then it stopped receiving text messages, and everyone said they couldn't hear me when I called them. Great
Some of you guys got a bad device, there are thousands out there working properly.
If some of you guys flashed a newer Radio, the one form the test-ROM, then this is your problem.
And some of you guys have a quite gay branded ROM (slow responsiveness of touchpad). The original HTC ROM on the FTP and even more so a cooked ROM would solve alot of your problems. But be aware, flashing without having a backup ready is going to void your warranty if you want to exchange it having a custom/non-original ROM on the device.
What's up Schaggo
I am experiencing the same problem these gentlemen are mentioning and my ROM is not gay or lesbian. It is the original one.
TC is my 7th HTC device and I can see the quality of the ROMs decreasing a lot on every new device. I feel like HTC needs a real competitor to move up its arse quicker.
All I can say is that it really annoys me to hard reset this [email protected] everytime I "accidentally" use a native feature called Flight Mode. By bluetooth seems to fly away and never get back.
Lots of time the GPRS settings have to be reconfigured too. Some people I know have problems with GMail IMAP4 accounts when sending messages after some time. I never had this problem on my Kaiser neither on my Niki.
The lack of a video driver really is an egg on our faces, because I can't believe my ole Qtek 9100 responds quicker than these "all the bells and whistles" Qualcomm 7200 super-duper geared up devices.
So, if you feel like not contributing, please do not mess around.
Your signature tells me you are a wise man, but your comments show me otherway.

Hi
I've tried many custom rom and the PB continue. "PB with the hardware oh BT".
Hard reset doent change anything.
my initial rom (SFR France) was working
custom rom (blackwidow + Bepe 058) are buging...
nedd some help !
Thanks alot for that input feaps. I guess I have to clarify a little bit.
My answer was supposed to be pointing in different directions. The first and general information I tried to contribute was, that it is not a common Polaris problem to have a broken Bluetooth unit. Which doesn't help at all to ppl affected, but it should tell them, that they probably got a bad device and should exchange it first before blameing htc in general and shouting for an iPhone.
It only was partially directed at specific persons. At madinga for example: did you try hardresetting your device? It could be a corruption in your system which causes all those problems. I doubt it though, if you suffer the loss of so many functions at the same time I suspect the mainboard to be broken. But nonetheless, hardreset it, see if its working, BEFORE you put your backup back on the device again since that could restore the corruption. If it doesnt work, exchange your unit, I hope you'll get a working one back.
My second line was directed at all people which have overwritten their original Radio with the 1.58.25.14 originating from the HTC Test ROM which can be found on the ftp server. The Bluetooth part of that Radio is flawed and leads to the problems described in this thread. I quite nicely pointed that out and told people where to have a look before shouting around. I do know that because I tried it myself and couldnt get my Bluetooth devices working. Once I flashed the original Radio back, my BT problems were gone.
And my third line - in which I may chose the wrong words, 'gay' for example - holds information targeted at people with for example the branded french SFR ROM or the original HTC french ROM. The SFR ROM is just horribly branded and if you go through the threads here you'll find people complaining about problems which then turn out to be related to the ROM. The french HTC ROM is flawed as well, it has severe problems with the volume control. I don't exactly remember what it was, but it's a flawed ROM, thats for sure. The German o2 ROM isnt flawless either, I know that because I originally had that ROM. Once I flashed my orbit 2 with the original HTC WWE ROM, I found it to be working alot better and smoother than with the o2 ROM originally provided. And this is where my last line comes into play: if you suffer problems related to your currently flashed ROM, they could be diminished by flashing an alternative ROM. But if your device is broken, and I personally and strongly believe that everybody fooling around in this forum should be intelligent enough and able to determine the sense of my words, eg. if he/she suffers a ROM problem or if the device just simply is dead and take appropriate actions.
And now to your contribution feaps. I feel personally attacked by your words. Thats why I defended my words in all the paragraphs above. Trust me, I've had enough mobile devices of all sorts to know what it means to get a not working once. Its frustrating and makes you want to throw it out of the window. And being able to see the quality decrease over time is just another drop on a hot stone. I agree. But be honest, if your BT unit works and stopps working once you engage a software based function, the problem is software related, dont you think? As for the GPRS settings, I cant tell. Since I use a free ROM which has the wizard built in (o2 removed it from their ROM) I didnt switch my SIM and the configuration worked, automatically and every single time. And I do use IMAP as well on my personal E-Mail account. Until now I didnt run across any problems, so I cant give you any feedback on that either.
So rethink again if I mess around or not or if I actually try to contribute and help the freshmen, coming into this forum and flashing whatever they find and breaking their devices. And recommending to flash the original HTC ROM, which should be/is the base for everything floating around, breaking your devices, is a serious input to everybody.
Edit: I forgot to add, pointed at nooms, there are cooked ROMs out there which stupidly have the new, flawed Radio baked in. Which Radio are you on? Try Start > Settings > Tab System > Device Information > Tab Version. Are you inadvertedly still on Radio 1.58.25.14 or back to (original) 1.58.21.23?
Hi everyone,
I agree with Schaggo completely. Most of the time problems have something to do with the software on the device. But I a not a tweaker like most of you guys, i've just bought my first (and hopefully not last) HTC phone. If i have problems of some kind, all i can do is reset the thing. A hard reset if necessary. I've done that many times. I can't change the software that comes standard and i don't think i should be the one who has to do that. Shouldnt HTC be doing that??
Anyway, Bluetooth keeps saying it has an hardware error. My radio version is a standard 1.58.21.23 but isnt finding any radiostations here in holland. Is it also broken? (sorry, i know, its a bit off topic)
You're right

Well put. Sorry for being rude, but I keep seeing people offending others day after day in this forum that used to be high level; but that doesn't mean I should act the same way.
I totally misread you and please accept my apologies.
My ROM is: 1.25.405.1 WWE
ROM Date: 12/11/07
Radio Version: 1.58.21.23
Protocol Version: 25.65.30.04H
One thing I could notice is that HTC has a flaw in the Flush HKCU to Permanent Memory While Shutting Down. Some keys are not written.
One example is the MagiCall (an app I use) registration key. The software maker had to write a flush app for doing that. Another example is the Start>Settings>System>Error reporting. No matter what you chose, after a power cycle or a soft reset, it always go back to "Disable...".
I have, also, already tested the device after the hard reset with no extra apps on it. Same lame behavior on BT...
So, SW QA levels are really dropping fast on new HTC models. That is pretty bad.
But anyway, I have an open case with HTC and if I find something contributive I will toch base with this thread.
Once again, sorry for being rude.
Best,

Then I guess you most probably got a bad unit. I guess the only solution at this time is an exchange.
The Radio-Firmware doesnt control the FM Radio btw The Radio-Firmware controls connections to the providers network, Wireless LAN and Bluetooth. But the FM Radio seems to be really bad in the Polaris, a lot of ppl I know complain about it.

No problem dude! There is no need for such an excessive appology. We are in a Forum and people have different oppinions and I think its totally acceptable to shout at each other. I just wanted to express that I'm not in accord regarding your judgement of my post. But thanks a lot, I seriously really appreciate it!
Yes, your device seems pretty standard to me and the scenario you described logically made me think of a software error. But this seems very unlikely now. I'm out of ideas for the moment then, I guess you have to return or exchange it too.
You are perfectly right about the dropping SW QA though. You can notice the registry glitch in other areas as well: backlight timer always reset to 30 sec, and there are more settings all over the place which don't get saved properly.
Again, no problem, everybody lets be cool
Bluetooth doesn't turn on
I have the same problem. Did anyone find a solution?
Also camera fails to initialize, touch pad is sometimes very slow for initial reaction. I have NO added programs beyond manafacturer originals and have tried a number of hard resets. Doesn't help.

[Q] Bluetooth handsfree problem

I have a Sony bluetooth head unit in my car which supports handfree and audio streaming profiles. I can play my music through the head unit just fine via bluetooth. I can also make and receive calls without problem when I am listening to the radio (ie when I am not listening to my own music). However, when I am playing my own tunes and I either make or receive a call, the head unit indicates I am on a call, it mutes the music but I just get silence through the speakers.
I used to have a Galaxy S Advance and it all worked just fine without too much configuration on the phone or head unit; basically just pair them up, make sure the right boxes are ticked in the bluetooth options and thats it.
Any idea what the problem could be? I've tried an upgrade to 4.2.2 but it didn't help...
Hi,
I have a similar problem. I can pair my s2 plus with cm11 from this thread to my car kit (Parrot MKi 9200). Playing music via phone on the car speakers works fine but when I place a call the receiving phone just gets loud static (and my voice very very silent).
I wanted to ask the developer of the cm11 I am using if he sees a way to exchange the bluetooth module (or what androis equivalent is) to the one of e.g. Android 4.1.2 because I know that one works perfectly. I am posting here because I havent reached 10 posts yet.
Of course I am open to other workarounds and ideas.
Thanks,
Kiesel
Bluetooth
Same issue here,
everything (music etc.) is okay, but the phone connection.
I'm connecting to my Ford Sync.
I can connect, but then the quality of the voice is very very bad, I can hardly understand anything...
I thing there's a configuration file in the etc/ folder, maybe that need some upgrade?!?
Hope someone can help, because I really like to keep CM11 on my phone...

How is this message supposed to be of any help? Of course we know that. We have seen a lot of threads. I have read the whole bug report including all the comments on googlegroups, I have browsed dozens of websites and googled my ass of. What I didnt find was an explanation (at this point I dont expect to find a fast solution anymore). After reading the googlegroups bug call I thought it was a problem with the bluetooth stack that apparently is being redeveloped by google. But here cooldevelopment said it isnt a google problem.
I fully understand that it must be annoying for you to see this question a million times but please understand, that it is also annoying (and unsatisfactory) to not know whats going on.

As this is a bluetooth problem topic, i just want to ask one question. Can't use the CM 11 and ROM's based on it, because the sound problems with connection in my car. So back to stock ROM. I flashed the cooldev's kernel to get a better battery life, but after flashing, bluetooth makes the same problem as CM. Do you guys have the same issue?

Hmm, interesting. I will try this out as well. Might probably be a week though, I am leaving for holidays tonight and cant risk making my phone unusable. Maybe somebody else is willing to give it a try?

Thanks now i know where to search the problem.
Hi,
here is a logcat of a bluetooth connection during a call on stock rom/stock kernel.
What I did:
-start logcat
-start bluetooth
-chose a contact
-call contact-
-talk for a minute
-hang up
-stop logcat
I then wanted to flash the mosh kernel and do the same again but the last time I checked there wasnt this huge plethora of different kernels to choose from. Very impressive work!
Could you tell me which one you would like me to flash and I would then redo everything?
Hi,
I tried installing mosh kernel 1.8 and 1.85 (for stock, init.d enabled) on sazy rom but it didnt boot. It stayed at the very first screen you get when you turn the phone on. I then installed your cm11 build8, connected via bluetooth to my car and had someone call me.
Attached is the logcat.
Do I need the samsung stock rom for mosh kernel? I thought sazy rom was a stock rom?

[Q] Nubia Z5s, WiFi Issue, Hardware or SoftWare?

Hi!
I have posted this message on another thread, but it's important so I create a special thread for it.
Indeed I received my Z5s yesterday and I have 1 week to find out if my WIFI issue is hardware or software. In the case of hardware, I need to send back my phone to china .
I received the phone rooted, so if I want to install the last update from nubia (1.30) I have different manipulation to do. Howevver, I am afraid that if I touch the rom, the seller can tell me "you changed the rom, before it was working so it's your fault. we don't give you back the money!".
So I am waiting he allows me to put back the official rom 1.30. By the way if anybody has a good tutorial (in english) about unroot and changing ROM, I would be very grateful
There is the description of my WIFI issue:
First (yesterday) I couldn't find any WIFI and then after a factory reset, I could find some wifi but not everything. By example in my laboratory, the general WIFI of the school appears (and is working) but not the wifi of my lab... Anyway I found out than others WIFI were missing too. (Maybe 15 were alright on 20).
Now (today), in my lab, I can't even find 1 WiFi! I have tried the factory reset and it still doesn't work. In the description of the last update (1.30), I found "6. 修复wifi小概率无法打开的问题 = Small probability can not open wifi fix problems".
It looks like my problem fix except that in my case it is not a small probability but it (almost) always happen...
So I need your expert opinion, do you think it is more probably hardware issue or software issue? Does any Z5s owner have this problem (sometimes or alway)? I've bought the phone in Eternal Team on Aliexpress, I don't know what is their custom ROM, did anyone buy the phone there and know what is the ROM ?
Thanks in advance for your help!!

18.1 hotdogb phone app issue

I hope this goes to the right place, if not can someone direct me to where it goes.
I'm having an issue with what appears to be the phone app. i can call out but when the recipiant picks up all they here is a beep like a old school fax whine. I've searched this issue and I'm at a loss. Phone is Oneplus 7t with 18.1 hotdogb with no Google.
Thanks for any help,
Lowdownin
It is not just the phone app from my digging. I am also having the same issue with Signal, as well as another dialler I have installed to test. It also happens when using a SIP client both in the Phone app and separately (Mizudroid).
Regardless of how the call is made (inbound to me or outbound to another), all they hear is a high pitch tone. I can hear them fine. Hitting mute stops the noise for them, however unmuting restores it.
I have checked and the phone records sound via the microphone and when in speaker mode and the playback is perfect.
As per @Lowdownin928, I am at a loose end. I am in the process of downgrading and will report if that has an effect.
New ROM released today, tried that first - https://download.lineageos.org/hotdogb. No change.
Downgraded to the last before the one I was having trouble with - lineage-18.1-20210926-nightly-hotdogb-signed.zip - however this has the same issue.
At this stage I cannot work out why the ROM could cause this but then using other ROM's does not fix, even when doing a full wipe. Something else is going on.
Am looking at reverting to a t-mobile or international ROM to go way back and see what happens. If that does not fix it then I am stumped, as it seem to not be hardware. Very, very strange.
OK, so have installed an original t-mobile version of Android 10.0.3 for the 7T and low and behold, it works perfectly. No issue with outbound calls from SIM or SIP, did not bother testing further.
For reference, factory default t-mobile rom I used was at https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_7T/T-Mobile_HD63CB/Q/, put phone in EDL mode and run the MDM. Came up fine.
Proceeded to System Update to v. 11.0.1.4.HD63CB. Reboot then tested for outbound noise on calls - no problems at all.
So at this stage the only way to fix this is to revert to the stock ROM, even with 11 it works fine. I have no idea what has happened with the LineageOS ROM but there is a fault somewhere. I am heading off to ask the question (and hope you will as well) but hope all this detail gives you an idea of where to go.
Just had a thought - there may be other ROM's that work fine, it could only be LineageOS that has this issue. If you don't need the feature set then look around in here.
Super surprised no-one else has had this issue, but there you go.
Success. Thanks to LuK1337, Lineage Team Member on the Reddit Support area this seems to have cleared the issue.
---
T-Mobile firmware isn't supported, you can flash retail one by following https://wiki.lineageos.org/devices/hotdogb/fw_update
---
So bootloader, flash lineage recovery, enter fastboot mode inside lineage recovery, flash all the .img's as laid out and then follow the rest of the install. Took a long time and careful reading but this was the key for the phone noise.
Thanks LuK1337.
Just wanted to let you guys know that I was also having the same issue and this solved it for me. Thanks so much dmc.kiint and LuK1337

Is it possible to create a firmware with the help of someone?

Hi there,
I'm not sure where to turn to at all and I'm sure if this firmware can be created and used successfully, there will be a lot of other users who will benefit from it. My issue is a little specific, but bear with me, I got myself a corsair virtuoso se headset for Christmas. I've set them up using the icue software on my PC, but when I used them on the PS5, the settings did not transfer. Google has revealed that the headset itself does not have any on-board memory for saving settings. It seems like Corsair doesn't really care about console gamers and I can't get help from them.
If there is anything that can be done to get my headset how I want it, I would appreciate it if you could point me in the right direction.
Is it possible to create a custom firmware with my settings and flash it directly to the headset?
Honestly, I don't even know where to begin. I've only ever rooted and flashed ROMs on my old S10.
Please let me know if this thread is in the wrong place or if it should be deleted.
Like I said, I am not the only one who has this issue with the headset, so if it can be fixed successfully, others may benefit as well.
My recommendation:
Add
VIRTUOSO RGB WIRELESS High-Fidelity Gaming Headset​
to front of this thread's title, thus mainly users having such a headset are addressed
