[LG V30 Questions & Answers] ChazzMatt:
The Quad DAC is audio processor for wired components via the 3.5mm headset jack -- normally headphones but some have used auxiliary cable to connect to car stereo.

Has nothing to do with Bluetooth.

The quad DAC will give you the BEST audio possible. Period. But your headphones or car stereo must be physically connected to your V30.

Yes the V30 has also Bluetooth, just like every other Android phones for the past several years. But Bluetooth has nothing to do with headset jack.

No Bluetooth headset can match high quality wired headset with a quad DAC.

If you must use Bluetooth, then that's another question.

[LG V30 Questions & Answers] iRS_:
dolby atmos is not even hardware... it's software and it has been ported to oreo.

at this moment you cannot match the v30's DAC's quality with any phone.

and music through bluetooth sound like s*** compared to how it sounds through a wire... (asuming you have a good source and, in some cases, you can physically hear the difference (i met people who were slighty deaf and they could not hear the differences))

you could try poweramp with it's effects and DVC.
[LG V30 Questions & Answers] skit777:
Do not tell me stupid about some ports because they are hopeless. I had s9 plus and dolby atmos in s9 is not the same as in the ports for other devices. There is not the smallest comparison. Even on wired headphones with s9 sounds great, there is nothing missing from it. And do not say that the V30 is such a miracle in terms of music because it is not like that at all. It plays very well when the amplifier that fills up the sound is played, without it the s9 with the dolby listens more pleasantly.
[LG V30 Questions & Answers] Wotta:
Skit, please don't drink-and-post. Put the keyboard down. Back away from the keyboard.

You're confusing two topics.

The LG V30 has far superior wired audio over any other mainstream cellphone. That's one of the calling cards. Nothing else is close. It's okay if you can't hear the difference; the S9 is better than anything you could buy a decade ago, and without really good cans (headphones), hardly anybody would notice. You won't notice with hyper-compressed 120Kbps mp3s, just as that "enhance photo" scene from the original Blade Runner was crap. But the V30 Quad-DAC really is the best... if your music was compressed with enough quality, your earphones are good enough and you're wired.

Not that kind of "wired" you are while writing your semi-coherent rants. The other kind. :cool:

Now to Bluetooth...

The LG V30 supports aptX bluetooth. So does the Samsung Galaxy S9. This is the top-end Bluetooth "codec", often coined "CD quality." Which really means, "better than FM radio, better than low-bitrate MP3, but not so great." Remember, CDs came out in 1982. Which was probably before you were born.

So what happens with the music? If you're listening via wired cans (the DAC), the Quad-DAC applies a lot of math (FFTs, smoothing, psycho acoustics) and tries to make the music as great as it can be. Roughly the equivalent of anti-aliasing an image. The S9 doesn't have all of that, so it will sound a smidge harsher, just a shade less accurate... but still better than anything a decade ago. And Bluetooth... on either one - the LG V30 and Samsung S9 have precisely exactly the same best-case aptX sound, because it's from your headphones, not the phone... will sound like something from three-and-a-half decades ago. Which was amazing at the time, and is good enough for an airplane, or low-cost earbuds, or if you're listing to hip-hop or rap, etc. But in those cases, why are you pontificating?
[LG V30 Questions & Answers] atirox:
Just to continue the point, Bluetooth audio still requires a DAC or Digital Analog Converter. However the DAC in use when using Bluetooth audio is in the head unit of your car stereo, not in your phone. When you play music via Bluetooth, your sending a digital signal to your "headphones" (in this case your car stereo), where it pulls the muscle of converting the digital signal into an analog waveform that can be played back by your speakers. This is why the same sound file sounds different when played back through your hi-fi system when compared to your car stereo. They use different DACs.

If I'm not mistaken (if I am please correct me), Dolby Atmos is software processing applied to the digital signal before it reaches the DAC, which is why it works over Bluetooth.
[LG V30 Questions & Answers] LightInDark:
Im pretty sure people have made a big mistake in their recommendation to you. The LG V30 has the high quality bluetooth audio feature along with its Quad DAC. Not just wired audio will benefit from it. Its designed for Hi-Fi bluetooth too.

The V30 has Qualcomms new aptX HD Bluetooth Codec. Which Samsung does not. LG are still retaining their place at top of the Wireless leaderboard with this device.

Samsung obviously cannot have aptX if it does not have a Qualcomm processor or chipset.
[LG V30 Questions & Answers] BROKEN1981:
Please don't post this BS information.

If you are running V4A, your Quad Dac is not working.

The music will have a down sample and an up sample.

V4A is for devices without a Quad Dac.
[LG V30 Questions & Answers] Sheephunter9000:
Just get the V30 if you are looking for audio.

I've used the v30 before i got my s9+, the audio quality that s9 delivers is nothing compared to what i get from my V30,I still go back to my v30 when I have to listen to my favourite beats. The v30 has a hardware advantage over the samsung. And both the phones have Bluetooth 5.0 support so you won't have any troubles playing audio via Bluetooth, but if you are looking for a superrior audio quality get a LG v30 with a good set of wired earphones/headphones. Sorry for any grammatical errors, English isn't my first language.
[LG V30 Questions & Answers] Audiokida:
Surprised to hear Dolby Atmos on Bluetooth. It's has to do something with speakers.
[LG V30 Questions & Answers] ChazzMatt:
Also, since you wrote that post a few months ago, we now have

DTS 3D Surround sound

on rooted V30, since LG put the DTS framework in the phones with recent updates. DTS is available on both wired AND wireless (Bluetooth) connections.

Why rooted? Because even though the libs are there, for some reason LG hasn't yet enabled it on unrooted stock firmware. But it's still a fantastic development, as long as you have most recent firmware. [MENTION=6815443]JohnFawkes[/MENTION] is enabling it on his TWRP-flashable zips, so you don't need to anything except flash Magkisk before rebooting (which you would do anyway). If you are not using one of his zips, then use the linked Guide above.
[LG V30 Questions & Answers] IshsXda:
DTS libs though lol, doubt s9 or really any phone has anything like that over bluetooth

(I posted this in the SmartPhone forum, but this is probally a better place)

I have the Verizon PN820 smartphone running wm5. I see roms for some GSM phones with wm6.1.

I would like to extract the WM6.1 from the GSM phone, and put it on my Verizon CDMA?

Is this possible? If so, is there a guide availiable that might lead me in the direction on doing this?

Thanks
[Windows Mobile Development and Hacking General] xplode:
yes you can flash the rom but your phone may not work after that :)
[Windows Mobile Development and Hacking General] MrTek:
Well the goal is to have a working phone after the flash :)

So I won't be able to from from GSM to CDMA then I take it?
[Windows Mobile Development and Hacking General] klmsu19:
uhh no he just answered your question. it may flash but wont work. its like saying can u put diesel into a Corvette- sure, will it run- no.
[Windows Mobile Development and Hacking General] MrTek:
Doh, so I guess it's no use trying it then if you are pretty sure it will brick the phone.
[Windows Mobile Development and Hacking General] phonuzer:
A Good Question

I believe that the trouble lies within the hardware of a device.

Unlike PCs that have the ability to run multiple OSs phones may not share parts that, given the right instructions, allow them to work on different infrastructures (e.g., CDMA and GSM).

I've not looked into this fully but know that certain chip sets on board a device are compatible only with that type of network.

While a PC/Notebook owner can freely choose his or her ISP it is more difficult, in the Cell Phone industry, than just simply swapping a Sim Card.

I know that a certain GSM provider is looking into locking certain phones onto their network via hardware; think of the implications.

Somebody may come up with a relatively simple solder-in of a compatible chip set or, perhaps, board swap to make this happen but then the consumer would have to balance the risks, money and effort of this option over purchasing a new phone and hopping over to a preferred service.

If/when standardization trumps the proprietary then your dream comes true; but can you wait?! :rolleyes:
[Windows Mobile Development and Hacking General] GnatGoSplat:
To make this work, you would have to:

1. Dump your WM5 ROM.

2. Separate dump into SYS and OEM packages.

3. Extract XIP.

4. Build new XIP with WM6.1 MSXIPKERNEL.

5. Build new IMGFS with new WM6.1 SYS folder.

6. G'Reloc the entire ROM.

7. BuildOS to create a dump.

8. Use Tadzio's tools to create a .bin, then to a .nb file.

9. Flash the .nb file.

This is sure to work, but isn't simple to do. If you're new to ROM cooking in general, you'll have a lot to learn before you can even attempt this. I've been cooking ROMs for 4-months and I still have a lot to learn.
[Windows Mobile Development and Hacking General] xplode:
And it will not boot this way, you have to mess a lil with the kernel (nk.exe) of your original rom in order to boot WM6/6.1, but GnatGoSplat is right , you need to recook a WM6.1 rom for your device with your devices OEM drivers and software in order to work. You can not use GSM rom on CDMA device because the drivers are difrend
[Windows Mobile Development and Hacking General] MrTek:
Hmmm....I wonder if it could be done.

At worst, If I have a bootloader in tact, I should be able to revert back,no?

I already extracted the WM5 ROM, and I extracted the XIP from a Startrek 6.1 rom already.
[Windows Mobile Development and Hacking General] GnatGoSplat:
Yes, as long as you don't overwrite the bootloader, you should be able to revert back, but I'm not familiar enough with your phone to know for sure.

StarTrek 6.1 XIP won't work as-is, the only part you can use from it is the MSXIPKERNEL. When you use XIPPORT and click "Make Packages", you will find MSXIPKERNEL in the Files and also Modules. You would do the same thing with the XIP from your existing WM5, then replace your old MSXIPKERNEL with the ones from the StarTrek.

For both ROMs, before you do anything, do "Write Maps" in XIPPORT. Then you can compare and it will tell you if you need to relocate any modules in your device's XIP to fit the modules from the StarTrek (you'll probably need to). You relocate modules with M'Reloc.exe. You will also have to manually edit the imageinfo.txt for each module in order for Write Maps to work. After you've done that, do "Realloc P" to relocate the modules. After that, you'll need to Write Maps to make sure there are no conflicts. In Map.txt, if there are any !!!!!!!!!, that means you have a conflict and will need to try different addresses in M'Reloc.
[Windows Mobile Development and Hacking General] MrTek:
Gnat,

Thanks for the help. I am really curious now that you say it can be done. :)

This is what I have done so far:

I started with the nbh file with WM6.1 from the StarTrek which I grabbed from here: http://xdaforums.com/showthread.php?t=374397

I then used Dutty's NBH tool to decompile the NBH into NB

Then used the extracted OS.NB with nbsplit (nbsplit -sp?) to break apart the payload and extra.

I then tried to use the rommaster tool to extract the XIP, but I always get:

[Info] It is a common ROM.

[Error] File struct error, xip end offset is 0x77422c11, but file lengt

is 0x025a95b0.

I suspect this might be related to the nbsplit -sp parameter?

diffeent providers

Hey, what about using another providers rom on your phone? cuz for the phone I have telus has a 6.1 upgrade, while bell doesnt seem to... would that work by any chance?

thank you for any help (have been trying to find information for ages)

Danial
[Windows Mobile Development and Hacking General] GnatGoSplat:
It can work, but usually you have to CID unlock the bootloader in order to flash another provider's ROM. I'm not familiar with Telus and Bell, but are they CDMA? If so it may overwrite some stuff like the provider setup info and PRL. You'll need to go into the EPST menu and make note of all those settings before you flash. After flashing, it would pretty much be the same procedure as getting a phone from that other provider to work on yours.

Definitely can be done though, my Touch Diamond is a CDMA Sprint phone that I use on Alltel.
[Windows Mobile Development and Hacking General] zozep:
Is there any forums, or FAQs or anything about doing this?? Bell will not release 6.1, and custom roms do not work....ridiculous that there is no support for this phone at all....
[Windows Mobile Development and Hacking General] GnatGoSplat:
You might try http://forum.ppcgeeks.com/.

That forum seems to specialize in CDMA phones. If there's an unlocked bootloader available for your phone, then it shouldn't be too much trouble. Some providers lock the EPST menu (SPC lock I believe it's called) and in that case you'd have to find a program or method to get the unlock code to get into that menu. Dig around the PPCGeeks and you'll probably find more specific details. I only had to do it once so unfortunately I wasn't able to commit those details to memory.
[Windows Mobile Development and Hacking General] danial.aw:
Thx for the link.... but from wat iv read before my phone (HTC S720, HTC Libra) doesnt seem to have a bootloader :S....

the vox does have one, im not too sure if it would work on it or not?

and specifically this phone has no support on any website that i can see :S....

is there any guide or something as to find the SPC lock?

Thx alot by the way, your the first member whos actually replied to me about this :D

[Windows Mobile Development and Hacking General] neilson:
It's time to propose this idea.

The unbrickable ROM. Works regardless of GSM or CDMA, keyboard or no keyboard.

Technologically speaking, why can't this be worked on? Even if it takes 12-18 months, it's worth the effort and time to finally create "The unbrickable ROM".

[ZTE Nubia Z17  Questions & Answers] Neogamaes:
Hello everybody,

I just received the Z17 Lite and I was really excited. Everything was going pretty well up to the moment I tried to make a video call on Skype. As soon as I start the video call the camera start, I can see my face 2 seconds, then stop without any possibility to turn it back ON... the camera icon is not active.

I tried the app messenger and here the video works but the sound and microphone become inactive as soon as I turn the camera ON. More or less the same occurs on Viber app...

I want to add that the camera works well alone, idem for the mentioned apps (without camera).

I tried to wipe all user data partition but didn't solve the problem.

I tried to install a previous firmware but again nothing change...

Do you have already experienced such a thing? Any idea?

[Galaxy S 5 Q&A, Help & Troubleshooting] mrfeh:
Hello folks. Just wondering if this is widely known, or specific to my phone/ROM.

I just switched from a Moto G to a Galaxy S5. I've played candy crush for a long time, and while it was always a battery drainer on the Moto G, it is an extreme battery drainer on the S5. When I'm actively playing the game, it takes about 2% off the battery per minute!!!

This strikes me as ridiculous. Anybody having the same experience?

Thanks.

It is an old phone with small battery and high screen quality and heavy processor ,

Best way save battery of your phone use 15% brightness. it work for whole day with call and 4g for me with 4 yrs old battery.

saga games normally eat lot of battery and make my phone hot( for S5 - very very hot).
[Galaxy S 5 Q&A, Help & Troubleshooting] Jayminghong:
Unfortunately it is normal... I came from Redmi 2 Prime, dropped 1% each 6 minutes or more playing heavy games. I miss that battery so bad! My Galaxy S5 G900M also drops 1% every 2 minutes, and this brand new battery was purchased last week. The reason for the high drainage is the 1080p screen (even if you decrease the resolution to 720p, the battery keeps draining as hell) and the > 2.0ghz processor. There's nothing we can do about it. If you want battery, I recommend you Xiaomi Redmi 4x. My dad owns one, and it drops 1% every 10 minutes or more on normal usage (each 7/8 minutes playing)

[Samsung Galaxy S9  Questions & Answers] metal450:
Last year, I bought my first ever Android - a Galaxy S7 Snapdragon. Unfortunately, I soon learned that without root & Titanium, Android provides no way to do a proper/complete backup (i.e. SmartSync doesn't backup any app data, & Helium backs up some but misses many - WhatsApp, LINE, Viber, etc). Thus I returned the S7, took a brief hiatus, & am now eagerly awaiting the arrival of a brand new Exynos S9 :)

I wanted to ask for any quick advice as to the "suggested" approach for rooting, so I can hit the ground running as soon as this thing arrives. As I understand it, there are 3 main approaches:

1) Install TWRP, stick with the stock Samsung ROM & flash SuperSU

2) Install TWRP, stick with the stock Samsung ROM & flash Magisk

3) Install TWRP, flash a custom ROM that's already rooted

Between 1 & 2, my understanding is that Magisk is preferable to SuperSU as it essentially accomplishes the same thing but without necessarily blocking OTA updates or some financial applications from working. True? So is there even any reason to consider #1? If not, any insight as to choosing between #2 vs (any specific custom ROMs)?

My long-term priorities are simply for the phone to run as well as possible, with as little maintenance as possible (i.e. as far as ease of getting security updates goes). I'm not really into lots of customization, experimenting, etc - I'd prefer to just get something up & running, stable, & stick with it. I will be using T-Mobile though, so I guess in either case I'll need to install this to get WiFi calling & VoLTE working. Also, I want to make sure that whichever root solution I choose, it can coexist with Secure Startup (the S7 Snapdragon's root couldn't, which was a dealbreaker for me).

Any insight would be greatly appreciated. :) The phone arrives Tuesday, I can't wait to get started!

[One (M9) Q&A, Help & Troubleshooting] madmatt2024:
ATT One M9. Currently on Version 3.38.502.31, S-ON, Rooted, TWRP. I'm trying to get it back to stock so it can accept the Nougat OTA. I read that I could just run the RRU from HTC to restore it. Finally had the time today to do it however I get a 132 signature error. I relocked the bootloader but still got the error. As I read up on it it turns out for some reason the encryption was changed between the 3.xx and 4.xx versions so the update won't work. I don't want to pay to get S-OFF so the only other option I can find is to get an older RRU for either my current version or the one after it (3.38.502.31 or 3.38.502.41) and then allow the phone to OTA. I can't find one. I can find the 3.38.502.41 .ZIP but from what I understand i NEED the .EXE version. Does anyone have one of these older .EXE RRU files or another method to get my phone to accept the Nougat OTA?
[One (M9) Q&A, Help & Troubleshooting] Flippy498:
There is no difference between the *.zip and the *.exe. (Well, aside from the fancy installer that gets used by the *.exe. It's not needed, though.) Besides, re-locking isn't just unnecessary it's actually highly not recommended unless you have a working RUU at hand due to the FRP that Google introduced with android 5.1.

Where did you read that you need an *.exe and/or that you need to re-lock your phone?
