Hi there,
I upgraded my Galaxy 551 to Gingerbread 2.3.6. All went well. Unfortunately it seems to be a common side effect that the Z and Y keys (and some others) get swapped. The fix is apparently to modify the file /system/usr/keychars/sec_keypad.kcm.bin. The ideal thing is to put the old file from before the FW update back in, but of course I don't have that anymore! But the existing one can apparently be altered. If I can copy it to the SD card I can alter it in a hex editor and put it back.
So, I rooted my phone with that one click application, and that went OK too. I installed root explorer and found the file. There were also some others in the same folder I may be able to use. But, I cant make the folder R/W (pressing the button does nothing) so cant do anything with the file. I also tried Super Manager with no luck.
I am new to the phone fiddling stuff so noob level instructions would be appreciated!
Think I have it sorted. I installed superuser and then Root Explorer allowed me to select read/write. Now to try sort out this file!
OK, seems that you need to edit the file /system/usr/keylayout/sec_keypad.kl. Did that. DO'H now my keyboard doesn't work at all! Glad it saved a backup for me! Not sure what I did wrong, only edited two characters in a text file! Even the power button doesn't work. Got to pull that battery out LOL!
It seems when the file was saved it was saved with zero size. When I try to delete it to replace it with the backup it says cant delete, read only. So, not sure how I am meant to replace this and fix this problem.
Any ideas, remembering that I cant actually use any buttons on the phone!
Guys,
I can't post in the official thread here:
http://forum.xda-developers.com/lg-g3/development/guide-headphone-speaker-volume-booster-t2819821
But I just wanted to confirm that if you root your device and follow the directions here, I've got confirmed working on the Sprint LS990 variant of this phone. The thread mentions nothing of this on Sprint or the LS990 but I can confirm that it is indeed working.
You'll need to:
1. Have root with SuperSU installed
2. Install Root Browser and 920 Text Editor (Available in market for free)
3. Navigate to system/etc and then mixer_paths.xml
4. Change file permissions to rw-r-r
5. Save to your downloads folder just in case you trash your phone or something
6. Navigate to markers mentioned in thread link above. The LS990 variant will have aforementioned markers listed approximately 15 lines later in the code. Edit them to your liking.
7. Save, reboot, pray not to get caught in limbo.
8. Enjoy having better sound than everyone else with a phone.
Just an FYI anyone attempting this: If you do not edit the permissions correctly when overwriting the file the phone will not boot. It will get stuck at the yellow sprint screen and you will have to preform a reset.
Root browser did not allow me to change permissions correctly and when going quickly I did not notice it when overwriting.
However, second attempt after recovery it worked great.
Thanks for the info TROPhouse
So i havnt edited yet but permissions look right here. Will they change after I edit and save. And then change them back right. I don't wanna get stuck since we have no custom recovery yet.
Did it. It was way worth sweatin through the reboot process. Haha.

I'm using viper. Works perfect. After installing I moved the app from data/app to system/app. Heard people were having it being stopped after using it for awhile and this was there fix for that.
Kept having permission issue and was kind of nerve wrecking with no recovery.... However, phone sounds awesome now!

What settings did you end up with. I used 68 or 69 on all mine and it's pretty good. Not sure if I want it louder or quieter but it's definitely way better than stock was.

I did 69 which seems perfect to be honest... I mainly hear music at the gym and usually use soundcloud... at 69, I don't even get close to full volume on the phone now. Its perfect
it seems like there are another few steps in this process that aren't being mentioned, like how to save the mixer_paths file because following the instructions and updating the lines I want to update then trying to save with 920 text editor ends with the message that it's a read only system file.
Anyone care to fill in the blanks as to how you get the update to stick?
thanks!
Super loud
Thanks! Great volume!:victory:

Don't know if this is too late to help, but...
I don't use 920, but my guess is there's an option somewhere (probably in settings for the app) to switch the file system to read - write mode, instead of read-only. I use the FX app, and that's what I had to do with it. Be sure to set it back to read-only when you're done.

SUCCESS!
So you need to download an app that will mount your system, I used an app called mount/system. You launch it then select Mount r/w. Once you do that you have the needed access to edit the files as listed. I used this guide as well and had success....hope this helps others!
copy the original mixer_paths to your memory by ES file
edit it by notepad++ on windows and put it again in your memory
copy it from internal to your /system
highlight it and set permissions rw r r
move it from /system to /system/etc/
reboot and enjoy
Has anyone tryied playing with bluetooth volume i cant find where to change it any sugestions?
Nice, I haven't had any issues with my phone being too quiet, but I also came from a Verizon G2. Those were noticeably horrible for volume levels, so the G3 is a welcome change.
In regards to all the questions about which app to use for which function:
You could use Root Explorer, or any other file explorer that has root capabilities (ES File Explorer, Total Commander). You do NOT need to use a specific app set and if your file explorer can't mount/unmount the system partition with root permissions, try a new one because that one sucks.
You also should not be downloading three separate apps to accomplish this. It's kind of overkill to have a file explorer, a text editor, and a system partition mounter when any decent file explorer has all three of those built in. I think ROM Toolbox even has all those capabilities in the free version.

Agreed but I downloaded ES File Explorer and several others and I was unable to find the ability to mount as r/w. If the option is in those apps, it's very much hidden so an app to mount your file system then an editor was what I needed and it worked.

ES's current interface does hide a lot, and is in almost every way inferior to the original interface. But the option is there. It's also in FX (File Explorer) which is my root editor of choice.
the pursuit of sound quality! bullet for my valentine cant be heard on stock!!!!!!!
tried this. guess i messed up. stuck on spark screen. sat and read through the pages here. gotta fix my phone when i get home tonight.
what did you change you volume levels to?
So can those who have successfully made the edits share what volume levels you changed and what are the new numbers? I've made the change to mine and even with my $100 earphones there's distortion at what I feel is a low level. I'm thinking maybe there's a balance among these that I need to achieve?
thanks!

You can fix the extsd write lock by using root explorer navigating to etc\platform\permissions.xml
You need to mount as RW and edit the file to match what I'm pasting below.
You can ignore the middle part about syscope info but change your permissions for "write_external_storage" the "access_all_external_storage" and the "write_external_storage"
Don't delete anything from the file or do this without paying attention. Do not alert the syscope permission in between the 2nd and 3rd permissions that relate to storage.
I found this method through Google but it's worked for me so fast with no problems. If you use root explorer and open the file in text editor when you save the modified file, the original file will have .bak appended to it. The guide I used only changed 2 of the 3 permissions I'm saying to edit but the sd lock fix went away after restarting but since I changed the permissions to what I changed below is been working gray even after restarting.
Remember be careful with how you edit the file, only change it in the places I showed to make sure there aren't any complications. If you type it manually make sure to match the formatting and symbols exactly. If you ate going to cut/paste make sure only to change the permissions to exactly how I show it.
I'm not responsible for any damage or issues caused by following this method incorrectly. Remember to save the file with the original name of permissions.xml and then restart the phone to check your now writable ext sd card.
Much easier to use "SDFix: KitKat Writable MicroSD":

I haven't tried that one but I've used the xposed framework app that is supposed to enable extsd write but it didn't seem to work properly for me or was at best unreliable when I tried it. I like knowing what patches or fixes are doing behind the scenes in case I need to change them or if there's a problem or an update and it stops working you can do it yourself especially when its add easy as copy and paste

This one hasn't worked for me very much on a few ROMs but I did have a little better luck using the Xposed module mentioned above.
Many thanks for the post, OP. I'll add that to my notes and try it on the next ROM that gives me write issues.
Awesome glad to be able to help. .. when I first upgrades yo NG6 I couldn't believe Google could screw up one of the best features in android phones compared to the iphone. At least we're able to workaround it in the current versions at least fornow

People wonder why Google apps which work fine are still considered "beta." It's because Google isn't done with something until they screw it up completely, preferably also changing the UI a zillion times so it's unusable on more than one level.

Thanks for adding the app add an option but can you give an idea of how well or functions and its reliability
I just rooted my phone a few days ago. My phone decided to upgrade to NG6 by itself and it crippled the SD card almost completely. I had some work arounds, but this just made it so much harder. I downgraded to NC5, had a problem, did a full reset and redid my phone. Did Towelroot V3, SuperSU, turned SDM.apk and FWUpgrade.apk into backups. Then I did the SDFix app, rebooted and now the SD card works like it did with MK2. I'm very pleased.
Hi, I'm relatively new to the rooting scene and I've been having trouble editing system files on my s3 gt-i9300
I'm running liquidsmooth V3.2 (stable) custom rob which is based on kitkat
My problem is this: whenever I touch the screen the capacitive buttons at the bottom light up for 5 seconds, this seems like a minor annoyance but over the course of the day it kills my battery (no setting to turn them off). I have tried going to /sys/class/leds/ and editing the maximum brightness files for the buttons to read 0 or just delete them but it won't let me save or delete the file, I've tried a few file managers and text editors but currently have Es file manager (and text editor) because I read it works... now here's the tricky bit, I already allowed R/W in both the Es root menu and on the file its self R/W/E for all users and triple checked that Es had SU permission, can someone please tell me what I'm missing? Or if there's another way to turn the lights off while keeping the buttons? Thanks in advance
Tl;Dr: can't turn off leds on the capacitive buttons on my s3, can't edit system files
I want to copy a file to the /system/fonts folder, but no matter what file explorer I use, they are all failing to copy any file to the folder. On ES File Explorer, I get "Permission denied," but when the system is mounted Rewritable, I get "Task Failed." Yes, my phone is rooted. Can anyone please help me out? Thanks.

Did you enable Root-Explorer in ES File explorer? Just go into the left menu scroll down and check it :good:

Yes, it was enabled. I found out that changing the system to Rewritable may have caused the error. I have an app called Emoji Switcher that always worked whenever I had to change Emojis from Google to ios7. When I installed this app: https://play.google.com/store/apps/details?id=com.blogspot.superthomaslab.mountsystemrorw&hl=en and set the system to RW, Emoji Switcher could no longer change the emoji file in the /system/fonts folder. I was forced to restore a nandroid backup, luckily without losing data. But I want to know what to do the next time I need to modify the /system folders when it doesn't let me.

cant really help you, but i may be able to offer some info.
im guessing you are either running Marshmallow, or have a nexus running stock?
if no, then the rest may be irrelevant.
i believe it was in M, google implemented some sort of system write protection, it can be bypassed but i dont know how off hand.
on nexus's, with the M update, google has the system so full, even with write ability, you may not be able to because there is no room.
maybe that will help you to look for a fix, maybe not lol

I have a Moto G 2nd Generation running 5.0.2. Although the info is irrelevant for me, I'll take it if I upgrade to Marshmallow. In my case, I'll just avoid changing the system directory manually for now. Thanks for both of your help!
