So I was trying to write nvdump on stock 4.4.2. But it is not sticking even after selecting 0 to 39939. I tried using DFS as NV writer was giving "not a valid nv file" error. It resets automatically on system reboots.
Only HDR AN Long seems to be resetting though.

EDIT: It finally sticked. Used the same LG.txt method used for sticking NV dump on Optimus G.

Guys, I understand this is for using Sprint G2 in India, but I still want to try my luck here for flashing G2 with my exisiting Sprint 3G donor phone info and use it in my legacy plan.
I had experience flashing old LG Optimus S and Galaxy S3 with my donor info, so I'm sure the AAA key and the HR passowrd etc are all accurate. The G2 I got off ebay is already on ZVD update and stock recovery unrooted.
I remember with Optimus S, I need to use Anycut app to make a shortcut of CDG2 and set PPP carrier to "undetermined" for the NV values to stick, otherwise they got reverted after reboot. But for this ZVD update, I found no such setting in HiddenMenu. I have got the ESN, MEID written, so I got voice, txt and inconsistent 1x data.
I'm thinking not getting 3G is still caused by my AAA key and password not sticking, since I never got the way to set the PPP carrier. I searched a lot at XDA and google, nothing at XDA but something here. So my questions are:
1. I know previous ver of ROMs such as ZV8 etc still has the PPP setting in the HiddenMenu, so should I revert to the previous ROM to flash and get 3G, then do the updates? Will I lose the written 3G related AAA key and password after going back to ZVD or ZVE? Seems like people were talking about this issue in some of the posts here.
2. In this quoted post, poster mention that he used this file for G1 to get NV stick, since you guys were working on Indian carriers, I'm very concerned if I flashed this it would brick my Sprint service? Is my assumption right?
3. My donor is a HTC TP2, so it's also a GSM/CDMA phone, but all my previous flashing experiences are for non-GSM phone (GS3, Optimus S), never dealt with flashing the IMEI. Should I flash my donor's IMEI to be safe or just take out the SIM and leave that part alone? Enabling the GSM capability would be nice though (I'm talking about using SIMs when I'm traveling abroad, say India or China). Would it be possible at all? Weird thing is after my flash and reboot a few times, my 1x started to get very unstable, and the phone even started to try getting on LTE network, of course the browser got me to ecare asking for payment, but it kinda freaked me out. I might just take the SIM out.
Anyways, thanks for all your help.
