[Nexus 5 Q&A, Help & Troubleshooting] Dani897:
there is a reason speakers have a sealed back. it's to keep the sound on th erear of the speaker from cancelling the sound on the front. dipole speakers don't have a sealed back and they drop a very regular decibel every octave below the wavelength of the baffle. there isn't much room for a large baffle in a phone so the back is sealed instead to try to preserve what little bass a small speaker can create. but the bass the speaker can create is soo little you may not notice the loss and instead notice some gain from increasing speaker excursion and effectively having double the cone area.

there are also ported/bass reflex boxes that phase shift the rear sound wave through a resonant chamber and a port to extend bass by putting the rear wave in phase with the front for a small frequency window.

there are other designs. but not much that will fit in a phone. i wouldn't say the design of the phone is faulty, just ineffective on such a small scale. maybe a trasmission line design where there was a channel that snaked around all the free space in the phone would be better. a rear loaded horn would be louder but takes up a lot of space.

as far as software, well there is only so much voltage that the internal amp can drive the speaker with. they have to find a gain ratio where there is enough headroom at full volume for most content to play without clipping. music is very dynamic and the louder something is the more extra energy you need to create an equivalent apparent change in loudness. you can raise the gain on almost any well designed system and not experience clipping on 90% + of a song but there may be a section of a particular song where you lose headroom and drive it into clipping. they probably went on the safe side with the hardware gain to preserve the quality of the music. but by all means if you prefer more loudness use a software mod.

there are some things that you could do, like software compression where the gain drops on the parts that exceed the max loudness. but it can make the music sound less lively. or you can just let it clip and maybe eventually damage the amp and/or speaker but that's probably not even a problem on such a small scale.

Alright folks, we're up and running. Just as the title says, this is the MK5 Boost/Virgin Mobile 4.3 update in flashable zip. Stock, zipaligned, basic. More to come in the future, but this should be enough to keep you busy for awhile. Enjoy!

PLEASE READ :)I've made a few changes to the wording of the OP, based on my own personal observations from running this build. This ROM is unrooted, even though it has the su and busybox "guts" in the build. Future builds will have all this cleaned up. In the meantime, when flashing, you must flash the SuperSU Update listed in the flashing instructions to regain root. Simple, I know :) Just thought I'd let you know! Enjoy.

Thanks:

Google, Samsung, XDA – For obvious reasons

Issues:This is an early run, so I’m sure there might be hiccups. You tell me!

ATTENTION!!!. THIS DOES NOT INCLUDE THE 4.3 FIRMWARE. AKA THE KNOX BOOTLOADER! SO HAVE NO FEAR OF FLASHING THIS BECAUSE OF KNOX!!!
[Sprint Samsung Galaxy S III] remotehugger:
So awesome !!! Thank You for putting this together - Is this deodexed also ?
[Sprint Samsung Galaxy S III] jdsingle76:
No not yet...more to come with all that!
[Sprint Samsung Galaxy S III] TheBritton:
Nice work!! :D

Is it possible to enable wireless tethering? Since updating to MK5 all wireless tether apps I've tried have failed. I'm not sure where to look to get them going again.
[Sprint Samsung Galaxy S III] jdsingle76:
I know@CNexus has a hotspot mod over at the MK3 build. That should work on this one as well. That what you are referring to?
[Sprint Samsung Galaxy S III] TheBritton:
Thanks! :)

I've seen that mod but didn't know if it was safe to flash on the virgin mobile build. Does that mod enable native tethering? I believe it's something in the MK5 kernel blocking tethering. I've tried all root apps like wireless tether, barnacle, etc all versions, betas, experimental to no avail.
[Sprint Samsung Galaxy S III] FloRida1999:
Thank you kind sir. Happy Thanksgiving!

Can I Flash a Sprint Galaxy S3 to Virgin Mobile?

Want to activate a Sprint Galaxy S3 on Virgin Mobile. Is this possible? Can I just flash a Virgin mobile Rom?
[Sprint Samsung Galaxy S III] jdsingle76:
Lol, no. Unfortunately it's not that simple. If you flash this, you'll have a Sprint phone with a VM/Boost rom. There are tutorials on here on how to flash from one carrier to another however.
[Sprint Samsung Galaxy S III] SgtMacabre:
I am having issues with root....I have tried all the other superuser apps...I jabe tried other superuser update zip and update fixer apps...I get a no root error on apps....i can not get root access for anything including titanium... any suggestions?
[Sprint Samsung Galaxy S III] jdsingle76:
Use philz cwm as your recovery and flash the super su update zip in the op. I couldn't get root back with reg.cwm.
[Sprint Samsung Galaxy S III] MaRz0o:
Haven't run into any problems yet. This is great. I did notice that for the notification panel, there isn't a Mobile Data toggle. Is it not included in 4.3? Is there some way to edit that?
[Sprint Samsung Galaxy S III] marcran75:
I've done a clean flash of this rom 3x and everything works nicely. Every flash I've flashed the hotspot mod you referred to as the final step. Up til the final step of flashing hotspot everything works and then after I get stuck on Samsung boot screen all 3 times.I think it's safe to say that the hotspot mod does not work for this rom.
[Sprint Samsung Galaxy S III] jdsingle76:
There isn't one included in 4.3, unfortunately. I noticed that day 1!
[Sprint Samsung Galaxy S III] jdsingle76:
Yeah, you are probably right. I know there are others trying to work this out too and haven't been able to. Most likely something inside the "guts" of the build. I'll consult some of the guys I know are who are a lot smarter than me and see if we can come up with something.

Also, for everyone, check the OP. I posted the deodexed version last night! Enjoy
[Sprint Samsung Galaxy S III] marcran75:
I just noticed this too. Don't think it has anything to do with 4.3. Before I ran this ROM I was running CNEXUS Sprint version and the mobile data toggle is included in that one.
[Sprint Samsung Galaxy S III] CNexus:
Boost must've disabled it...I know verizon did that on the S4, so it's a possibility

If you can post this file for me, I can make a flashable to enable all the hidden toggles for you guys

[Sprint Samsung Galaxy S III] MaRz0o:
Here's a zip file to the databases folder. It didn't have system.db but it did have settings.db and some other files.https://www.mediafire.com/folder/pbufbe79o8z84/

[Sprint Samsung Galaxy S III] CNexus:
Yes sorry, "settings" got autocorrected because i typed it wrong haha.

But I'll whip up a flashable sometime today to enable all toggles
[Sprint Samsung Galaxy S III] TheBritton:
Thanks for the info on the hotspot mod.
[Sprint Samsung Galaxy S III] marcran75:
I've been experiencing some stability issues with WiFi and data connection. WiFi toggles on and off by itself and sometimes I'll lose data connection altogether. I used ##72786# and when phone reboots it won't connect.Go into about device-status and my phone # and MIN are changed. This has happened to me twice forcing me to revert back to stock.
[Sprint Samsung Galaxy S III] jdsingle76:
Wow...that's a new one on me. The only issue I've had was with my default browser, and clearing app cache and data helped with that. What modem are you running? And when I first booted days ago, it took awhile for data to "catch," but once it did, no issues since
[Sprint Samsung Galaxy S III] marcran75:
I'm using MK5 modem. Probably didn't give it enough time to stick. I tried prl and profile updates before I tried ##72786# and phone wouldn't connect. I'll reflash and give it more time before I start restoring everything.
[Sprint Samsung Galaxy S III] jdsingle76:
When I first flashed my very first iteration, [MENTION=4645794]CNexus[/MENTION] had to reassure me that it would take lol. It happened to him too. I did the activation reset too, updated prl and profile and it finally settled in. Hope it pulls through.
[Sprint Samsung Galaxy S III] SgtMacabre:
Thank you!! Not only did the Phil's recovery work with getting me root access again...butn it looks nicer and has some nice additions! ! Thanks for the info.. im gonna keep the philz!!! Thanks for your work with the virgin s3 .. im glad we are getting some dev love on XDA. lol!! Other sources are not quite so succinct....
[Sprint Samsung Galaxy S III] remotehugger:
I agree - thank you jd for all your work - hey Sgt, out of curiosity, after flashing, does your pulldown bar still say Virgin Mobile ?

I totally missed this whole conversation. Thanks for helping, as always, [MENTION=4645794]CNexus[/MENTION], you are the man...
[Sprint Samsung Galaxy S III] jdsingle76:
I'm gonna go out on a limb and say yes to this one :) It won't change your pulldown bar, and it should also read "Virgin Mobile" on your lockscreen now too :)
[Sprint Samsung Galaxy S III] jdsingle76:
Has anyone successfully downloaded and flashed the deodexed version of this ROM? I'm trying to find out if some of the issues are with the upload I posted or on the user end. Any feedback would be appreciated. Until I hear back, I have temporarily taken the deodex link down. Thanks for your patience!
[Sprint Samsung Galaxy S III] jdsingle76:

You are correct my friend. Just flashed to test, and it works perfectly. Here's a screenshot everyone. Thanks for this CNexus.
[Sprint Samsung Galaxy S III] nidpancho:
did a clean install of the odexed mk5 rooted build with the mk5 modem.

It seems as if signal strength has improved a bit, however mms doesn't work in my house.

signal has always been bad here in my house but I was able to send mms barely. Now it seems sms gets sent faster but mms won't work at all.

I'll try in places where signal strength is better tomorrow.

Virgin Mobile user BTW.

Thanks for this will try it out now :D

UPDATE:

No mater what I do I cannot get this thing to root properly. Apps still say I am unrooted.
[Sprint Samsung Galaxy S III] jdsingle76:
Flash the super su in the OP using philz cwm recovery. I couldn't get it to stick with regular cwm.
[Sprint Samsung Galaxy S III] F3AR420:
Oh wow lol well I currently have cwm installed where can I get this other recovery?? I am sorry if I sound like a n00b lol
[Sprint Samsung Galaxy S III] marcran75:
What version CWM are you running? I used ROM MANAGER from the play store to update to CWM TOUCH 6.0.4.3 and I had no issues at all getting root to stick.
[Sprint Samsung Galaxy S III] MaRz0o:
I found that installing the Phil's recovery and then flashing the superuser zip given allowed root.
[Sprint Samsung Galaxy S III] remotehugger:
I had to reflash supersu before it took - using philz recovery - its pretty nice - sometimes have to tap an extra time or two but it sure is customizable - and backs up quick too -

Really sorry. ROM INSTALLER not ROM MANAGER. And it won't recognize your device if you're using MG2 modem. I did it awhile back when I was using MD4 modem.

Yeah still says my phone isn't supported. Maybe i can use the one for the sprint phone? Im using 6.0.3.1 CWM

[Sprint Samsung Galaxy S III] jdsingle76:
If they doesn't work, try flashing philz recovery and then the supersu update. Both are in the OP

Sorry. Trying to help but I'm starting to think I might be complicating things more.

lool very much again thanks a million :D
[Sprint Samsung Galaxy S III] Purponic:
I would like to personally thank everyone involved in this project. I know the Boost/Virgin Mobile community really appreciates it. I don't know about the VM guys, but development was pretty stagnant with the Boost version. We appreciate every little thing we can get immensely! Keep up the good work! I hope to see some more Boost/Virgin specific roms in the future.
[Sprint Samsung Galaxy S III] jdsingle76:
Thanks for the kind words Purponic. This is the reason why I do what I do. I am on the Boost variant as well, and learned early on, with the E4GT first, then the SIII, that there are very few, if any, Boost/VM users that do any type of ROM development, building, etc. I hope to expand on this build and bring more and more exciting features to the Boost/VM community. I am still learning, and have ALOT to learn, and couldn't possibly do this alone, so make sure you thank those I have listed in the OP next time you see them bouncing around XDA, especially [MENTION=4645794]CNexus[/MENTION], and any others you see in my threads that offer help almost daily. Great dudes, all around. Thanks again, and enjoy the build:good:
[Sprint Samsung Galaxy S III] Mr. Struck:
VM is in the same boat, while we can piggyback on the Sprint ROM's, it is really nice to see someone like JD working his butt off for the Android community while doing everything else he does (Marine, family man, and college student, my hat is off to you my brother!!!); can't wait to see what the future holds and am happy to do any testing anytime! Thanks again JD.
[Sprint Samsung Galaxy S III] F3AR420:
probably late as hell responding but i installed it and it went off without hitch once I got my recovery sorted.
[Sprint Samsung Galaxy S III] freesunshine:
Thanks!

I totally 2nd this statement! I'm on Boost and jdsingle76 have been really helpful when I was using ET4G. I know our S3 is same as Sprint version but it's nice to have someone with Boost variant to see exactly what is happening with the flash and etc.

I also want to thank all those who involved in this project, especially jdsingle76, to making this phone awesome to awesomeR! :D

Has anyone experienced significant battery drain with the Deodexed Rom? With the Stock Odex Rom, I could be at 100% and have my phone in sleep mode overnight, nad when I wake up, it would be at 96% after 6 hours. With this rom, I just lost like 6% of battery within the hour, while the screen was off. I have the same apps installed as the previous ROM, any suggestions?
[Sprint Samsung Galaxy S III] freesunshine:
I've always wondered, is it ok to flash ROM, wifi fix, SuperSU update, then knox APPS remover one after another without rebooting?
[Sprint Samsung Galaxy S III] marcran75:
That's exactly how you're supposed to do it.
[Sprint Samsung Galaxy S III] F3AR420:
No battery drain issues for me at all. Battery life has actually been great though that might change with time.
[Sprint Samsung Galaxy S III] remotehugger:
I rear about that battery drain also, but have not experienced it on the deodexed ROM - actually getting pretty decent battery - I under clock down to 1.2ghz which probly helps a little -

Check out the thread for dkp kernel in Original Development, decimalman is currently working very hard on 4.3 TW compatible kernels.

Wifi tether update!

Just found a solution to wifi tether for MK5. The app costs 1.99 but well worth the money if you use tether a lot. Install instructions:

1. Buy/download/install app

2. Enable your wifi on your phone(it's weird, I know, just trust me)

3. Configure wifi this way

Interface wlan0

Method 3 - HostApd

Channel 1

Encryption wpa2-psk

Drivers nl80211

"HostApd Patch"* <- UNCHECKED

4. Click back button(this saves settings)

5. Click enable wifi

6. Profit

flashing kernel and rooting galaxy s3

Hey guys! I have accepted the ota update to 4.3 and have never had root. Can I odin the PhilZ kernel without root and then get root by launching recovery and flashing supersu?
[Sprint Samsung Galaxy S III] jdsingle76:
Philz is not a kernel, it's a recovery. But yes, flash Philz using Odin, then flash SuperSu update 1.8, reboot, profit. Make sure you have Supersu downloaded to your phone before you flash to recovery :)

---------- Post added at 02:22 PM ---------- Previous post was at 02:14 PM ----------

That's because Boost uses CDMA and iccid is to identify SIM card which Boost do not use.
[Sprint Samsung Galaxy S III] Vanilla Bean:
Just wanted to add to the kudos for jdsingle76. I was doubtful until I got the wifi tether app working according to his instructions. Even though I'd screwed up and allowed a 4.3 update with Knox since I'd recently got the GS3 and hadn't read the warnings in time, it's OK. I'd already got started rooting using Team Epics root kit, and then flashed PhilZ's Recovery and overcame the Knox problem with SuperSU 1.8 flashed from recovery. Now I flashed this deodexed stock version and made it a keeper by getting the wifi tether going. Now I'm moving in the home and office furniture because I have things to do! Speaking of battery drain, I've got the fat 4200mAh battery in mine but the wifi does take it down as fast as I charge it, maybe a bit faster even.
[Sprint Samsung Galaxy S III] jdsingle76:
Did you full wipe before switching from Aosp to this tw build? And are you using the MK5 modem? I assure you lte works on this rom. And also that everything else works perfectly. And for the iccid, did you run ##72786# after you flashed? Just a thought :).

I flashed this ROM. Thanks Jd! Will I be able to update to the latest ota when it comes out even though I voided knox warranty? Will I have to un root too?

Edit: I want to know if I would be able to update ota from my phone, without having to flash the ota?
[Sprint Samsung Galaxy S III] jdsingle76:
I'm assuming you mean the next one after MK5, which is assuming there will be one :). But if you have cwm, and an update comes out, just wait until someone(probably me, lol) posts a flashable zip and you'll be golden.

Anyone know where I can find MK5 kernel?
[Sprint Samsung Galaxy S III] jdsingle76:
The wifi fix is the stock MK5 kernel :)
[Sprint Samsung Galaxy S III] ttittoo:
The reason I ask is because when I sell this (when the s4 comes out) I don't want to sell it rooted and the person that buys it would surely want the update without having to root. Any ideas if it would be safe to accept the ota from my phone? Thanks Jd, you the man! This knox cra* is making my head hurt.
[Sprint Samsung Galaxy S III] jdsingle76:
If you accept that ota while rooted, with custom recovery, it won't take. Odin back to MG2(add long as you don't have Knox on your phone!), flash the OTA(that'll put MK5 and Knox on) and then sell it!
[Sprint Samsung Galaxy S III] ttittoo:
Ya, I already flashed the MK5 ota before flashing your ROM. But then I rooted and flashed this and voided knox warranty. I guess I could just unroot and then install the update...
