Well, I've made great progress in 48 hours. I've figured out how to root, push, pull, backup, etc., from an adb session in Windows. So far, I have my original build.prop file backed up, system folders backed up, and apps backed up!!!
So, back to my original need plus more questions:
1. Does anyone out there have notes for enabling GSM for USA operation on a Verizon LG VS870 (Lucid 2 w/4.1.2 OS) or notes for any phone originally tweaked by Verizon for CDMA?
2. Another site has a list of things to tweak for a 3.2.4 OS, but would prefer known good notes for 4.1.2.
3. is there any reason to change any of the lines tweaked with "vzw" (FYI...will not be using it at all on a verizon system):
Line 17: ro.product.name=l1v_vzw_us
Line 30: ro.build.description=l1v_vzw_us-user 4.1.2 JZO54K VS87011A.1370604225 release-keys
Line 31: ro.build.fingerprint=verizon_lge/l1v_vzw_us/l1v:4.1.2/JZO54K/VS87011A.1370604225:user/release-keys
Line 170: ro.build.target_operator=VZW
Line 172: ro.config.ringtone=00_VZW_Airwaves.ogg
Line 194: ro.afwdata.LGfeatureset=VZWBASE
4. This is what I plan to try adding (or editing) to the build:
a. Does anything look out of place?
b. Does it matter where I insert this stuff in the lines of code?
telephony.lteOnGsmDevice = 1
telephony.lteOnCdmaDevice = 0
telephony.rilV7NeedCDMALTEPhone = false
persist.ril.mux.noofchannels = 10
persist.ril.modem.mode = 1
persist.ril.features = 0x102
persist.radio.vzw.cdma.mdn = deleted
persist.radio.ap.phonetype = 1
persist.radio.lte.mm.disable = 1
ro.telephony.default_network = 3
ro.telephony.gsm-routes-us-smsc = 1
Thanks in advance,
