[Script] USB Mass Storage (UMS) for LG Optimus L9 - LG Optimus L9 P760, P765, P768, P769

[Script] USB Mass Storage (UMS) for LG Optimus L9
I've made script that's on every boot changing default USB mode to UMS.
On USB plug it mounts your External SD (doesn't matter if you have swapped IntSD with ExtSD or not )

I've tested it on stock V20B and V20C roms - works great ! (should work on other roms too)

OMG. GREAT. Something I wanted since long time. Now I can connect the phone to my LCD TV and BlueRay Player directly in USB mode. Thanks (if works)
If this was possible is such a simple step, why those idiots RESTRICETED it?
=====================
Naaaaah!!!
EDIT: Did not work on P765 V20D Hongkong Rom. Tried all USB modes, but it did not loaded as a drive.

On my Sony Blu-Ray it works like a charm

It won't work if you will change USB Mode .
With this script phone on boot is automatically changing usb mode to UMS (UMS is not listed - after connect you should see all positions unchecked)

Now Not working here.
Its strange. I lost 3G connectivity. Is it by any chance related to 3G? May be I am stupid to ask this, but I flashed this and lost 3G. Getting Error 106, internet connection lost. :crying:
Edit: It was NOT working here. Typo error)

This script isn't doing anything with 3G.

Thank you very much !
It works perfectly on my P760 with JB V20C Europe (your ZIP file was flashed through CWM Recovery 6.0.3.1).
It was one of the most important regression since my previous phone ! :highfive: (the other one is call recording : I tried everything possible and didn't get any result )
@cmahendra : I didn't get any issue on my 3G connectivity; so I don't think there is any relation.

I know.
Just tell me which usb mode you are in?
EDIT1: After 2/3 restarts and using net on WiFi, again checked 3G is ok. Could be some stupid combination error. Fine
EDIT2: Deleted 30ums.

Not working on P760 V20B
tried all usb modes.

Currently, I only have the external SD card which appears as the second partition when I plug the phone. Would it be possible to have internal memory (storage/sdcard0) on as the UMS drive partition ?
Thank you in advance

Sorry, by reading "Now ...", I assumed it was working for you, I didn't look the sad smiley.

As it was said in the original post, I am in "Charge only" USB mode (the first one in the list). When my phone is plugged to my computer, "Storage Mass" text appears under bold "Charge only" text and I can see my SD card loaded as an external drive.
But it didn't work on my first plug. So, I thought it was because I made a mistake in CWM Recovery because, I remembered I saw a message when I asked my system reboot and I answered "Yes" without reading it (stupid reaction...). I decided to restart CWM Recovery, flash the ZIP again and take more care about the message on reboot request (in fact, it was just asking if I want to reflash the recovery because it could have been replaced by the ZIP, this time I said "No").
On the next plug, it worked. I also deactivated USB debugging before.

Sorry! It was my typo mistake. that was "NOT WORKING"
I think I also saw that question and did same mistake. In fact I saw this message few weeks before also for some other cwm session, dont remember when, and therefore I was also clicked on "Yes". Will check later.
THANKS. This info should be there in OP.
I hope mateo1111 saw this post.
EDIT: I tried this again but did not worked.
Selecting "NO" in CWM while rebooting.
I am in "Charge only" USB mode
Deactivated USB debugging mode option.
Still this does not work for me. I see Removable disks but when clicked, it shows error like in attached screenshot.
Or is it not for V20D? I am on V20D Hongkong.

Remove my script and try to manually run commands (using adb shell or terminal):
Code:
su
echo "/dev/block/vold/179:61" > /sys/devices/virtual/android_usb/android0/f_mass_storage/lun0/file
setprop persist.sys.usb.config mass_storage,adb
If it's still not working - reboot phone and manually go to "/sys/devices/virtual/android_usb/android0/f_mass_storage/lun0/file" (check if directories aren't different - maybe that's why script is not working)
You can manually edit "file" - content should look like this:
Code:
/dev/block/vold/179:61
Then execute commands:
Code:
su
setprop persist.sys.usb.config mass_storage,adb

Phew!! This time it worked with ADB SHELL way. THANKS A LOT!!!:good:+2
First I checked the folder location, it was ok but the file named "file" was showing as 4KB size. When I copies it on pc to examine, it was 0 bytes. I even tried to edit on place in phone, but got error message, "no space to copy file".
Then I started ADB SHELL and gave above commands after su and it worked perfect. It started checking driver. Then I changed USB mode to "CHARGE ONLY" mode and pc loaded generic Mass-Storage driver and DRIVE I: appeared in "My Computer".:good:Even rebooting was not required. It changed in live mode.
Something is not working with Flashable Zip, otherwise the process is working fine with manual changes. After flashing the ZIP, the content of "file" file should change but it was 0 bytes, that means the ZIP is not able to make changes in CWM mode. This should be rechecked. I am on V20D HK
I was also confused and misguided for Debugging Mode to deactivate, which was not necessary. Now Debugging Mode is on but still the MASS-STORAGE is working.
Then why did LG removed this mode?
Thanks again.
EDIT: Internal Storage does not work right? But that is just fine as most important data is in external card..

I have managed to get it work with PAC-man 22.1.0, i think it must work on CM 10.1 also.
I had uninstalled the LG Drivers and ADB Drivers and then my L9 (P760) was recognized from my PC as Mass Storage.
I hope this can help.

---

It is working fine on artas' ROM (I used the manual way).
I was looking for this from the first time I connected the phone to PC, really thank you!
Edit: it is possible to mount a second mass storage using "lun1" instead of "lun0". I can't find the internal sd device....

---

the internal sd-card can't be mounted as mass storage at the Moment
