I'm trying to root the LG Exalt LTE, or LG VN220, from Verizon. Initially, I've attempted the common rooting kits, such as KingoRoot as well as the tools described around XDA. However all failed. I suspect the cause to be the restrictive permissions of /data/local/tmp, which prevents execution of binaries. I believe any kit using this location will likely fail to achieve anything.
As such, I've been looking to achieve the same using manual techniques. The first step, as in most rooting activity is to put the device into USB debugging mode. To do this on the VN220, first compose ##7764726220. When asked for a service code, use 000000 to access a special menu. Select the Developer Options > USB Debugging and select On. There is an additional menu below named Select USB configuration, from which you can select Media Transfer Protocol or RNDIS among other options.
With that done, you can verify that you can now communicate with the device via ADB. To do so, download the Minimal ADB and Fastboot bundle. While I was successful in querying the device with ADB with
From there, I've try to boot in different modes, which are accessible by turning off the phone, and then powering up the device while holding the Volume Down button. This will boot into a white screen with some options, including the "Safe Mode" option which I attempted. The second mode is the "Firmware Upgrade" mode which is accessible by again, powering down the phone and powering it up again, but this time holding the Volume Up for 3 seconds.
Attempting to run the following fails:
fastboot oem unlock
fastboot oem device-id
Trying to run apps from the internal storage such as su or even using the chmod command only results in "Operation not permitted" messages. So even temporary root seems rather difficult.
At this point, I'd like to know if anyone has any advice on additional things I could try to root the phone, or even have temporary root.
Thanks in advance
can you make a software for the LG vn220 phone that I can install to block the internet service from that. and after I install the software it's not possible to bring bake the old software whit internet service or when I restart the phone.
