[LG V20 Questions & Answers] investinwaffles:
Hi folks, wondering if anyone has dealt with this issue before.

I have a Kenwood KDC-X701 headunit in my Jeep which supports APT-X. I have never had an issue with any of my android phones connecting to the headunit, specifically my Galaxy S5 running LOS 14 nightlies. Always auto-connects and displays APT-X on the headunit (NOT AAC)

I broke the screen on the S5 so I bought an LG V20 (LS997) knowing full well that development has ceased on the V20, with the assumption that a stock ROM will at least be fairly stable.

Enter the issues I am having with my new V20, latest Sprint build 100% stock.

When I let the headunit auto-connect to the V20, it displays APT-X but no audio comes through the head unit unless I initiate a call (no music regardless of application, no google maps audio, etc). After disconnecting the call, it goes back to not passing audio.

If I disable auto-connect on the headunit and manually connect my V20, it connects and displays "AAC" and will play audio without issues.

Now, normally I would say "screw it, I found a workaround", but I tested my S5 and V20 side-by-side with some Modest Mouse FLAC files (through PowerAmp), and APT-X makes a noticeable difference in clarity. The mids/highs sound muddy on the V20 (AAC), and super clear on the S5 (APT-X). Enough so that I spent quite some time debugging it to see if I could figure out what the source of the issue was.

Is this something related to the APT-X HD codec? I spent an hour just now messing with it and I can NOT get the V20 to pass audio when connected via APT-X, but it passes audio just fine via AAC. 100% sure this is the V20 because every other Android I have tried (even my friend's S7, stock VZW), and none of them have this issue!

TL;DR

My V20 won't pass audio using the APT-X codec, but will pass audio using the AAC codec. My head-unit always auto-negotiates APT-X and I have to manually disconnect/reconnect through my V20 to get it to negotiate AAC and pass audio.

Any help/feedback would be greatly appreciated :(

EDIT:

Here are some pics I took of the actual display

Driving me mad because I like to just get in the car, hit play on the headunit, and not need to take my phone out of my pocket
[LG V20 Questions & Answers] G2T:
Same problem here

This could have just as easily been my post word for word. I got a V20 over the weekend, replaced my old stereo with a x501 so that I could have bluetooth. Took me about a day to figure out that I have to disconnect and reconnect in order to get sound, even thou it is clearly connected via bluetooth and I can see what song is playing on the stereo. I too noticed that this is happening when its using APTX codec, when I disconnect and reconnect it for some reason switches to AAC and works perfectly. Yep, and it's very annoying because I do have to get into you phone and disconnect/reconnect every time I start my car. After that everything works as expected.
[LG V20 Questions & Answers] KUSOsan:
Have you checked online for a firmware update for the radio? I have the kdc-x599 and mine had an update specifically for Bluetooth related issues and mine streams just fine over the aptx codec.
[LG V20 Questions & Answers] investinwaffles:
Thanks for the advice! I was actually on a much older firmware version so I went ahead and updated my head unit (from v.109 to v.116) but unfortunately there was no change :(

I am going to try a full factory reset on the head-unit this weekend but it's not looking promising unfortunately

It is pretty annoying to have to initiate the connection from the phone, especially when you hop in/out of your car like at a gas station and end up not remembering till you are on the road. I was looking for a widget or something that could auto-initiate a specific bluetooth connection instead of having to go into the settings (or toggle bluetooth on/off) but haven't found one.

I really like the concept of the phone and the hardware, but LG is just "not good" at Android. My best advice is for them to run just pure AOSP and fire their OS development team, but hopefully Google will force their hand with Project Treble.

Compounding things further I dug out my S5 with Lineage OS to set it up as a garage phone and remembered how much I miss just pure AOSP (and root access, and no bloatware, and stability)...

I wonder if the KDC-X702 and latest models have the same issue, but confirmed that it was an issue specific to the V20 and it seems futile to change the whole head unit because of the shoddy bluetooth stack in the V20.

So, I will grudgingly deal with the issue and try to push it from my mind every single time I get into my car until I can find a suitable replacement for the V20, but the damn headphone amp has spoiled me which makes it hard. Maybe someone will come out with a nice streamlined Type-C DAC/AMP combo but I am not holding my breath

EDIT:

Last ditch effort - I am going to send an email to both Kenwood and LG tech support to try and get some engineering assistance.

I know LG is going to write me off, but Kenwood seems actively engaged in development (last firmware update for the KDC-X701 was March 15th, just days ago). It's not on their end of the equations so I am not sure what they can do anyways

Is your phone rooted? That sounds kinda similar to the issue of using certain audio mods or tweaks on the V20. I use Viper and to activate the mod over Bluetooth I have to use an app created by WETA that basically forces a phone call so it can activate the effects. My TMobile version doesn't have any problem playing over aptx on mine regardless of audio mod though but it sounds kinda similar.
[LG V20 Questions & Answers] investinwaffles:
No, I am 100% stock, Sprint ZVD firmware (latest update)
[LG V20 Questions & Answers] G2T:
Mine is stock and I did update the firmware on the headunit(x501) to 116, this is what Kenwood told me which I tried with no luck...

Once i told them this did not work they asked me this...

None of the phones on their list support aptx, they are all very old phones. What I don't understand is why does it try to use aptx only when the headunit boots, then it will switch to AAC when I disconnect and reconnect bluetooth from the phone. If the phone is setup to use aptx, wouldn't try to negotiate aptx everytime it connects? Anyway, AAC works but its a hassle every time I jump in and out of the car. Is this just an issue with the LG V20 or Kenwood? I dont' have any other bluetooth devices that use aptx to test with... and since other phone I have only use aac I can verify the headunit either.

On a side note, I also have issues with hand mode. when I connect the phone via usb it will only provide power. I have spent no time troubleshooting this so it could be as simple as a cable issues. I was curious if you have connected the LG V20 via usb and been able to use hand mode?
[LG V20 Questions & Answers] KUSOsan:
[MENTION=9043624]G2T[/MENTION]

Do you have a Sprint variant as well?

I have a T-Mobile variant and a Kenwood unit and I have no issues with using aptx. Mine doesn't display the codec on the unit but I have used logcat to verify that it doesn't switch back to aac as I've had Bluetooth issues before on a certain TMobile firmware

[Xiaomi Mi A1 Questions & Answers] aj2893:
My friend will get an Mi A1 from India and plans to use it in Sweden. Is there any difference in the Global Mi A1 and the Indian Mi A1? Does the Mi A1 in India support 3G and 4G frequency bands in Sweden? Just want to know about the network coverage of the Indian model in Europe , especially in Sweden .
[Xiaomi Mi A1 Questions & Answers] Omarod:
Find out on this website

Willmyphonework.com
[Xiaomi Mi A1 Questions & Answers] KeinBernd:
Don't do it. The Indian model supports different LTE bands (3,5,40,41) and especially lacks support for the vital band 20.

Apparently all networks in Sweden (Tele2, Telia and 3) use bands 3, 7, 8, 20 and 38.

Band 20 is usually the most deployed one in all of Europe, as it allows higher range per BTS/cell tower and is therefore cheaper to deploy. It's especially used outside of urban areas. Either way, in the best case you're gonna be stuck with LTE in urban areas only. Based on personal experience I can tell you that owning a phone without B20 support is no fun in Europe, although I can't relate it to Sweden.

I suggest you get it through one of the Chinese resellers instead, such as a certain site with a name close to "best gears" *coughcough*...
[Xiaomi Mi A1 Questions & Answers] asawi:
It's true that band 20 is widely used in Europe. But is there really an Indian A1 version without it? A proper Android One A1 and not a 5X with A1 ROM?As I understood it, but I could very well be wrong, the A1 is only available as Global.

Either way, check the specs and make sure band 20 is covered and you're good!

Edit: Seems I was wrong! There seems to be an Indian A1 without band 20. http://www.mi.com/in/mi-a1/specs/

[Moto Z2 Force  Questions & Answers] elijahaf97:
Is it possible to convert my T-Mobile branded z2 to stock retail version? I no longer live in the USA so the T-Mobile add-ons don't do anything for me.
[Moto Z2 Force  Questions & Answers] noXcape:
Yes you can. Just be very carefully of what Android version you are on...there alot of files around now that are nougat and Oreo and it's very very bad to go from Oreo to nougat. Once you are on Oreo you basicly can't go backwards. There is a retail software thread around here somewhere.. I'm pretty sure you have to fastboot flash it all on your own(no flash all)... Like I said though be cautious because the beginning of the thread has the nougat files and the mid/end has oreo

Also. You will most likely have to flash the T-Mobile modem with the retail stuff.

[Huawei P10 Questions & Answers] BraskOviedo:
Hello,

I have bricked my P10 and I need some files for Oreo:

I have the system.img and the cust.img

I am missing:

boot.img , recovery and userdata.img

I have got the 2 I have extracting the update.zip but the other 3 are not available in the update.app from huawei inside the zip.

Can anyone upload the files for me or upload a TWRP backup as I have TWRP Oreo up and running in the P10 but I formatted everything and forgot to backup first.

Thank you very much.

PS: Resume I please need a TWRP backup of the OREO rom or the 3 missing files above, thank you very much.
[Huawei P10 Questions & Answers] martindoublem:
there is no longer a boot.img and recovery.img for oreo. If I am not mistaken you are trying to use the multi_tool right?

You can use the ramdisk kernel and recovry_ramdisk files as replacement.

Userdata is not necessary from what I recon.

If you have a running TWRP I would strongly urge you to try to find a fix using that way. Such as by running HWOTA if you can.
[Huawei P10 Questions & Answers] BraskOviedo:
Thank you but I can´t because HWOTA doesn´t recognise the TWRP. I am trying to use the multi_tool 8 but without success. I don´t know how to fix it at the moment, maybe SAT time?
[Huawei P10 Questions & Answers] BraskOviedo:
I will try to not flash the recovery because I think TWRP is a better option at the moment?
[Huawei P10 Questions & Answers] BraskOviedo:
The problem is that I can´t find any Oreo ROM that I can flash with TWRP and it would be awesome if someone share one although if it is very unstable just to be able to recover an OS.
[Huawei P10 Questions & Answers] BraskOviedo:
Ramdisk kernel would be boot.img and recovery_ramdisk the recovery?
[Huawei P10 Questions & Answers] BraskOviedo:
I have tried and it doesn´t recognise it so I think they are not the corresponding files it seems....
[Huawei P10 Questions & Answers] DallasCZ:
just download all 3 update packages of oreo from firmware finder. unpack them with huawei extract tool and you will have all partitions images. Or if you have erecovery pay 10 bucks to funky huawei and they will help you.
[Huawei P10 Questions & Answers] BraskOviedo:
I have a SAT near home, if they don´t help I will do the funky option...

[Samsung Galaxy Note 8 Questions and Answers] fogoticus:
Long story short. I have purchased a brand new imported UK Galaxy Note 8 SM-N950F. Upon opening the brand new box, I got nothing out of the ordinary. Booted the phone and what do you know? It's locked on Vodafone UK... (it didn't accept my Vodafone RO sim for some reason). Talked with the guy, the guy freaked out because he sent me the wrong device and told me I'll get a phone unlock code within the next 3 days.

After I'll unlock the device, I wonder. Can I flash a normal, non bloated BTU firmware onto the phone over the UK VOD firmware that's currently on it? I adore the device but I ****ing hate being stuck with carrier **** especially knowing that Samsung is slow with updates and it being a carrier based firmware, it will be slower also. On my old S8+ I did the same.. worked like a charm, Knox not tripped, phone was running stock non bloated firmware and to this date is receiving updates normally and is working properly.

I heard that Samsung has decided to region lock the devices from S9 forward (or was it Note 8?) but I'm not worried as I like the UK firmware.

TL;DR: Got a Note 8 UK Vodafone locked phone. Can I flash over the UK VOD firmware, a normal BTU firmware?
[Samsung Galaxy Note 8 Questions and Answers] fogoticus:
I am asking strictly because I heard that the Note 8 might be region locked and that could maybe interfere with my plans.
[Samsung Galaxy Note 8 Questions and Answers] me2151:
its not region locked.
[Samsung Galaxy Note 8 Questions and Answers] RossTeagan:
Yes, you can!

And I wouldn't worry about the region lock. Because UK and Romania are both EU countries and the region lock is enforced for the greater EU area.

This is what it shows on Eu Region Lock devices.

[HTC U11+ Questions & Answers] andreipaval:
I have an European model U11 Plus, Dual-SIM, 6GB, 128 GB, and just goat a second SIM card.

I see in the settings that the secons SIM can only be configured as 3G, no 4G option.

Is this true or am I missing a setting ? Was expecting both SIMs to be 4G.
[HTC U11+ Questions & Answers] matchung:
you can not run both SIMs in 4G mode.
[HTC U11+ Questions & Answers] daheufster:
True

Indeed, what is already an improvement over the older phones who where 'stuck' on 2G only even when only the second SIM was activated (and so the first SIM disabled).

For the U11+ if you disable the first SIM automatically the second SIM will be able to work even with 4G+.

But it shouldn't matter since if two SIMs activated you can run the data over the other SIM. Unless you want to try VoLTE for your second SIM phone number.?

2nd Feedback

Thanks for the dedicated thread. If I may, some more nitpicking about rudimentary things.

ast.install has hard coded file names of ast scripts, that's not very portable:

l_Scripts=( "ast.ls" "ast.np" "ast.pm" "ast.ops" "ast.settings" "ast.storage" "astcore" )

I have packages ( "ast.ls" "ast.net" "ast.pm" "ast.ops" "ast.set" "ast.sto" "astcore" )

so more generic pattern for handling like ast* may be considered. In case of renaming, ast.install could have a file renaming template (ast.rename) with say key value rows for generic renaming procedure before starting the actual transfer/installation. Another thing it could try to perform chmod 755 after installation.

EDIT: Looks like you have it but it doesn't work as system is read-only for say /system/xbin installation directory. So installation can be performed either by hand from a file manager with root access or TWRP recovery (install script for easy TWRP install may be a solution).

Do you have any comparative performance observations regarding background network access?

2a. The interesting are the influence of size of the blacklist on system/apps behaviour (fluency, speed, memory usage or possibly noticed negative consequences re some specific apps). By default whitelist contains less than a dozen of items, blacklist is empty. What packages would you consider safe to remove from the whitelist, like LG weather widget? Will 300 blacklisted items be completely practical to have?

2b. Battery consumption changes and practical benefits measured re having hundreds of packages blacklisted vs normally empty blacklist.

2c. I remember you mentioned a FW app you installing on the end of device restoration process, what functionality separate FW app provides for your use case, or is that just an app like AdAway?
