Hello! Most devices like Nexus 4 or our S4 Mini have problems with USB OTG functionality - they can't provide power to connected device. When I was browsing through some system folders, I've found a directory /d/regulator/8921_usb_otg/8921_usb_otg. In this directory, I can see voltage values, but I'm not able to edit them. Can someone help me how to edit max_uV and min_uV files? Folder called "enable" can be changed to 1, but other folders no.

Use ES file explorer, tap the world icon on the top left, Tools, Root Explorer OFF To on, give root permissions, after tap on root explorer again (On the Word now, not on the "ON" button and tap Mount System R/W On the menu that will appear.

From the screenshots he has posted, the folder is already in R/W mode
@lipalok
All the files in that folder have readonly atttibutes set r--r--r--. Try copying the files to some folder in the sdcard, change them, then move them back to the folder and set the same permissions as before.

Hi guys!
The "file" you are trying to edit is not a file, but sysfs node.
To set or read a value you do this:
adb shell
su
cd /d/regulator/8921_usb_otg
echo 1 > enable
etc...
try to set max_uV to USB voltage which is 5V, it's in uV so:
echo 5000000 > max_uV

You just have to put the apk file of the FMradio on your sd card...then you open a file browser like astro-file-manager...you look for the path (you have chosen for the apk-file) and open the file by tapping it-->you have to tap "install" and it should work

rxx means you should just check Read and unchek the other two options in a row (if they are checked).
rwx means you should check Read and Write, and uncheck the third option in a row.
In your case you should uncheck Execute in every row.
Thanks for this post. I'm having exactly same issue with the RadonMod v2.5. Did you manage to install fmRadio?
Did you get the apk from stock?

Anyone found a solution???Mine still doesent work...
I just switched from my M7 to the M8 yesterday. I was excited to have the external SD for saving pictures, moving apps, but mostly to host my backups. I have since unlocked my bootloader and rooted the device. Unfortunately I'm unable to write any back ups through TWRP to the card. I was wondering if anyone found any fixes? I've already tried SDFix but it seems not to work with our device. Any help would be appreciated!
Sidenote: I know this probably belongs under development but I'm unable to post yet as my post count is too low. Thanks again!

You will need to edit platform.xml file in/system/etc. Are you comfortable ?
I'm not sure. If there was a tutorial that was available I could possibly follow it. Otherwise is this something that could be included in future rom builds? I wouldn't mind waiting.

Look for nextapp's SDFix in the play store.. Root and system write protection off is required. It basically edits the file for you (also backs up the original)

the quick way? go to the module thread in Original development and follow the instructions. You'll have to do it at every boot though unless you're on a rom that supports init.d support. If you're on stock I made a guide to disable it on boot automatically without init.d support

I tried it again using "su". I'm pretty sure that is what I used the first time as well because when I entered the command the super user prompt came up to allow access for terminal. Same results. Didn't see any confirmation. Exited app and tried running SDFix and failed again. I then followed your link to your thread and followed step by step. Got all the way to the point where I was trying to save the text document at the end and got the prompt that I could not save the file.
I'm usually pretty good at following tutorials and I'm sure I'm not skipping steps but who knows. I think this one has me defeated lol.
If you put it on your SD card try just /sdcard/wp_mod.ko

Sure. Here it is:
You need to make following change to platform.xml in /system/etc.
Add <group gid="Media_rw"/> under WRITE_EXTERNAL_STORAGE and WRITE_MEDIA_STORAGE(or similar).
Save. Set Permission to rw-r-r or 644.
Reboot and Enjoy
Good luck :good:

Well I ran through both tutorials (yours and the others) once again. Entered the command twice to confirm and got the message "failed file already exists". So I'm assuming that part went through fine but still unable to run SDFix successfully or edit the install_recovery.sh file. Wouldn't allow me to save through es text edit or the standard one.
So now I'm trying to manually change the platform.xml file. When I navigate to system/etc I don't see any file named "platform.xml". Also tried a search through es file explorer and couldn't find any file. Any thoughts?

Are you mounting it as r/w in the file explorer? It doesn't seem like you're doing that. I know the module works.. You can't just install the module and it's magically writable.. you still have to make it r/w in a file explorer before you make any changes. I don't use es. I use root explorer and there is a r/w button on top.

As of now recovery doesn't support exfat formatted cards, If your sd card is formatted as exfat it will fail in recovery. You need to either format your external sd card to fat32 or just wait until the recovery is updated to support exfat. It will once they get kernel source code

How far out do you think that is? I was figuring I could just get a cheaper card for my backups. Only thing is if I remember correctly Fat32 only supports up to 4GB files correct? I remember my backups being a tad over that so getting another card might not even make a difference.
Whenever I try to move a file to internal storage when I connect my phone to laptop, it won't let me transfer. Same thing when trying file explorers on my phone.
ARHD, Elemental Kernel, S-off?
"Won't let me" means exactly what?
Maybe your firewall is blocking it?
Does your device show up as media device in WinExplorer?
What kind of files and size?
Have you tried Superbeam or Airdroid = transfer over WiFI?
Or even better: set up a shared folder (shared with everyone) on your laptop's C: drive, get File Manager HD or ES Explorer on your phone and transfer files via the network share.

To pull any file from your device, you need to know its path. Once you know the path of the file, enter the following command to pull the file.
adb pull <path-of-the-file>
For instance, lets pull the Settings.apk which is located in the /System/app/ folder on your device.
adb pull /system/app/Settings.apk
The file will be pulled and saved in the ADB folder itself.
And DCIM folder is in sdcard (At least mine is in sdcard. Maybe it differs from device to device.)
Hope I helped.:good:

There are one or more Magisk Modules that will make it appear for all intents and purposes that you've overwritten or changed a file. It will do what you need. Because root is systemless, you can't (and shouldn't want to) actually change or delete any system files for real. I don't know the name(s) of the Magisk Modules that will do that, as I haven't had a need, but many users in this section have suggested others use such modules to do something similar to what you want to do.
running "settings list global" on adb shell gave me this location "lock_sound=/product/media/audio/ui/Lock.ogg" I was gonna check on root explorer but forgot im not rooted right now but hopefully that is it.
I just am trying to change the sound when locking the phone.

you have to create a magisk module yourself and replace the file, with the one you want.
google around for a template of a simple magisk module, recreate the directory inside the magisk module where the file you want to replace sits on the phone (system/product/media/audio/ui), drop the new sound file there, zip the magisk module template and flash via magisk manager and do a reboot.
dynamic partitions don´t allow for r/w mounting. replacing the file systemlessly via magisk during bootup is the only way.
