After I was playing with different ROMS and flashing my Optimus X2 i Semi bricked my phone. I don’t know how it happened, I don’t know what I did wrong the error just popped up. When I booted my phone it wouldn’t go any furter then the Clockwork mod with the following errors:
- E:Can’t open /cache/recovery/command
- E:Can’t open /cache/recovery/log
- E:Can’t open /cache/recovery/last_log
No mather what I did, I couldn’t boot into the system because of the /cache partition.
After researching and checking the different options I had, I found a tool named nvflash.exe and with this tool i solved the problem above.

Preparing the things that you need
Downloading the software:
Prepare Phone
- Power down phone
- Remove battery
- Hold VOL_DWN+VOL_UP & plug in USB connection from computer (note, your phone will not visibly respond but it will boot to APX mode quickly)
- Open Device Manager in Windows and you should see “APX Device” listed with an error
- If not, rinse and repeat
Install Driver
- Right click on the APX device
- Select ‘Update driver software’
- Select ‘Browse my computer…’
- Select ‘Let me pick…’
- Select ‘Have disk’
- Browse to directory you extracted the *driver* software to above
- Select ‘NVIDIA USB Boot-recovery driver for mobile devices’
- Accept any warnings, including the big red alert (you may need to disable UAC)
- Now in Device Manager under ‘USB Controllers’ you should have an ‘NVIDIA USB Boot-recovery driver for mobile devices’
- If not, uninstall the driver, reboot, rinse and repeat
Testing
- Make sure your phone is still plugged in to the computer.
- Start => Run => CMD
- Navigate the the directory you extracted the NVFlash archive to (2x-v10b-1300166062-nvflash.zip)
- In my case:
cd D:
cd D:\Private\Downloads\LG\flasher\2x-v10b-1300166062-nvflash - Run a harmless command such as “nvflash –sync” (in CMD)
- You should get something back like:
Nvflash started rcm version 0X20001 System Information: chip name: unknown chip id: 0x20 major: 1 minor: 3 chip sku: 0xf chip uid: 0x0280404444803457 macrovision: disabled hdcp: enabled sbk burned: false dk burned: false boot device: emmc operating mode: 3 device config strap: 0 device config fuse: 17 sdram config strap: 0 (You may get some kind of boot image error but thats oké)
Repairing the Phone
- After everything has gone well there is a file named flash.bat in the directory.
- Run flash.bat from the directory
- Wait for flash to complete and device to reboot
After following these steps you should boot into a original non rooted LG Optimus X2.
After this part it is y0urs to flash him again into a ROM that you like.

Is this specific to your particular phone or the android platform. I have a motorola defy that is giving exact error messages…..Do you think this should work on this phone or is it specific to your phone
I just realized it is giving me a “count mount” error and not a “count open” error. Is there difference?
Yes it is the same error, the mine also was giving mount error sometimes.
Yes this is for a specific Phone the LG optimus X2 (P990), maby there is a solution for your phone.
What kind of phone do you have?
