[Q] Seriously desperate...

[gatorhater73]

Ready to sell this phone... tried everything I know how to try... Dev Edition Verizon S5, CAN'T UPGRADE from stock NCG. The most I can do it root... any ROM I flash is nonfunctional on Verizon's network with NO SIGNAL. Replaced SIM, flashed modems, etc etc... I think I'm just not sure how to do it with a dev edition... seriously feel like I'm missing a step. Would like to start from scratch. Does anyone have a stock image of a G900V Dev Edition I could work from, since I'm starting to think the one I've been working from is somehow the incorrect version. Thanks!

I would but I'm trying to avoid locking the bootloader, if possible. Didn't intend on having a developer device, but now that I do, I'd like to try to maintain it's use as one. Bought this phone on swappa, seller didn't give any indication that it was a developer device. Now I'm concerned he did something to it prior to selling that is causing me difficulties. I don't think I should be having these network difficulties, but there could very well be something I'm supposed to be doing with the modem that I'm just unaware of. I figure if I can get back to the way this phone was when it was new (when the original seller bought it) I'd at least have a clean slate to work with.

I don't think so, but thanks... I think that's the same device firmware that the retail version comes with, which will lock my bootloader. I've actually considered just flashing it anyway and saying the hell with an unlocked bootloader, since I didn't really intend to have one to begin with and apparently there's nothing I can do with it, anyway (none of the unified builds work on my device, anyway) but this is a last-ditch effort to preserve it if i can, and I'm hoping some dev will be willing to help me diagnose my problem.

It's not like there's a ton of development going on for Dev edition. I'm loving the retail version of the phone just rooted and running some Xposed. Like it so much, I went out and got one for the wife too and I paid full retail for both to keep my old unlimited data plan. Hers I just left out of the box stock. Will be interested to see how Lolipop looks when it drops to her phone. Sure hope we keep root with Lolipop, I use the heck out of my hotspot, to the tune of about 70gb/mo ...

I'm far from a developer, but this may help. I also bought the phone without realizing what it was I was getting into and had similar problems flashing the Optimal rom on my dev edition s5. I could flash but phone would hang on the activation screen with no signal. I eventually succeeded. As near as I can recall this is what I did:

I dirty flashed Beantown 4.4.4 rom (twrp) over my 4.4.2 stock firmware. then flashed n12 firmware (included stock kernel, and modem) from dev edition make an update .tar thread (odin) (http://forum.xda-developers.com/showpost.php?p=56604757&postcount=2). I did a factory reset after flashing. Switched to art. Flashed optimal with clean reset, but did not flash kernel. Later flashed koontsez 4.4.4 kernel. Still running Optimal

Good luck.

Had marginal success using this method... Have been able to maintain a 3G signal, but no LTE after first boot. Rather, when I first booted, I had LTE and thought I was good, but since my first reboot, I can only get 3G and nothing I do can get it back so far.

This happened after I flashed the update.tar (with aboot.mbn removed) and I have note gotten LTE back. Is there something I can do with my aboot.bak that I'm missing?
