[Q] Any reliable way to change MAC address permanently on E980? - LG Optimus G Pro

Hi guys. I've been trying to dig for answers for the past couple of weeks. Somehow, about 3 weeks ago my wife's and my E980 ended up refusing to play nicely the wifi network. Did some trouble shooting, eliminating the router, other devices, only to find out that, for some reason, our phones now both had the same MAC address. This was causing a conflict, which was easy to prove just by shutting off one or the other phone.
Since finding this out, I've been digging around, but coming up almost empty. Wireless Mac Address Changer seems to be the only app I can fnd that will allow me to change the mac (with about a 50% success rate), but I'm hoping to find something that actually sets the address permanently. Most of the guides I've found here mention a file I can't find on my system (variations on VMAC). WCNSS_qcom_cfg.ini looked like it might be helpful at the start, but it looks like any MAC address put in there is overridden as the system boots.
I'll probably end up having to flash back to stock and slog my way back to my current install, but I'm hoping to put that off for a while if possible.
I'm running G3-OPTIMUS.G-PRO.V5.4 Final, Build Number KVT49L-12/10/2014
Baseband version APQ8064T-MDM9X15M/M9615A-CEFWMAZM-3.0.113060
Kernel 3.4.0
Can't remember what my wife is running specifically, but it's one of the similar ROMs.
Thanks for any help.

If youre running a Asop rom, you can flash the custom kernel for it, it has a bug that gives the phone a different mac address upon reboot.

Thanks for the reply, but no dice. I'm running a ROM based off of LG firmware. It goes into bootloop when I try to flash the custom kernel.

And, after months of trying spoofers, googling all over the internet and back, I stumbled across this post in the LG Optimus 4X HD forums. All those searches, just to stumble across bcmdhd.cal
I haven't tried it at home to see if it resolves the conflict with my wife's device, but the new mac address shows up in the system settings, which none of my other attempts did.

No wifi internet/constant rebooting

So, to give a little background, my sister got a Koodo HTC One V - the thing would connect with wifi, but could not hit the internet (tried on various networks). It would after a few days use start to reboot over and over again every minute or so. Resetting to factory settings would fix it (the rebooting, not internet access) for a few days, but then it would start over again. Koodo sent her a replacement, and it had identical problems. Koodo refunded her, but let her keep the HTC - she got herself a Samsung GII - same internet problem, no reboot issue.
Anyhow, I've got the HTC One V now, and I thought I'd see what I could do with it. I'm not at all experienced with fixing phones, but I'm tending to think it's a provider specific ROM issue where 2 phones had identical problems, and where a third phone from a different manufacturer had the same internet problems. If someone thinks otherwise, and has suggestions, I'm definitely open to suggestions. Otherwise, I'd like to try putting a custom ROM on the phone and see if that fixes the problems. So, I'm looking for suggestions as to what ROM I should try.
My priorities in picking a ROM are as follows, in order.
1. How safe the ROM is (how likely I am to not brick the phone in putting the ROM on)
2. How easy the ROM is to put on (I'm a beginner - at least when it comes to phones, not computers)
3. How easy the ROM is to use (I'll be giving the phone to my dad who has never used Android)
4. Speed
I know I'm not going to get a ROM that scores high in all those categories - those are just the things that matter to me, and how I rank them in importance.
Any suggestions? Thank you ahead of time!

I wonder if its ever going to stop.
Have never seen as many wrong forum posts as I have here. Guess that's what happens when you call a phone the One.

Then kindly direct me to the correct forum. I click on "forum", there's immediately 5 options; General Discussion, Operating Systems, Chief Central, Swappa, and Legacy Devices, immediately followed by a big heading for HTC One, with its second item being One Q&A, Help & Troubleshooting. Rather than marveling at how that could possibly bring someone to post here when they have issues with an HTC One, it would be more helpful to direct them to where they should go. Thank you.
Its marvelous because you are the closest to the right phone name...and the fact that there have been over 20 other users posting here as a result of the wrong device as well. Do a search for HTC One V and you will find the correct forum.

Thanks, that helped quite a bit. Now... I've gone through the directions, and installed a new ROM and kernel... the instructions say the first boot will take awhile - any idea how long? The phone has already been sitting for 5+ minutes. If it needs left longer, I'll leave it - otherwise, it would be nice to know I should be doing something else with it. Thanks!
Edit: A little research makes it sound like I'm in a bootloop... I'll try to take care of it myself, but if I need help, I'll come back here.
So, I gave up on the ROM I was trying, and installed CM10. It flashed just fine, but I still have no internet connection. The phone will connect with the router, I've rebooted the router, and it still connects, but no internet access. This is exactly what the phone did with the stock ROM. I'm trying to research any possible issues with CM10 - in the meantime, anyone have any ideas of what directions I should go to try and correct this?
To be clear, this is internet access over wifi - the person I'm giving the phone to will NOT be using internet over the mobile network.

[Q] Huh... I've tried digging up stuff, but I think I need some advice

Howdy folks, I think I'm in an odd situation here...
I have a Note 2 from Videotron that's been unlocked (they won't warranty it, Samsung's given me the run around), but seems to have developed an odd issue... Basically, I'm running stock firmware, but have been rooted. However, my phone gave up the ghost the other night and I figured just flashing the stock Odin image (from Tesh) would just resolve it.
Well, it got my phone back up and running... sorta. I can't seem to access the inernal storage (which isn't a big deal as I have 32gb micro SD card), and somehow my IMEI number shows up as 'null'
I did some digging around and I found out about the nv_data.bin (and related files), so I decided to dive into the EFS folder and lo and behold... those files seem to be missing. Wifi and bluetooth check out as functional.
I've tried some of the tricks to rebuild it, reflashed the stock image, modem, csc. and no dice.
I've seen talk of being able to hex edit the files from another device to get it up and running, which I don't mind doing. I've been flashing ROMs for a few years now and this is the first time I've encountered this. Also, I'm an IT tech by trade, so command lines fon't scare me.
However, this is stumping me and I really don't want a $730 mini tablet... or if you folks know of a service that rectify the issue for me, I'd appreciate any info. Though, I'd prefer to DIY myself before sending it out to a shop.

That would probably solve my issue other than the fact that the one tool I need (here) keeps 403ing.
If someone sent me that tool... I might be able to fix my IMEI issue and be done with it. Otherwise... I'm contemplating of getting a crackberry Z10 and be done with android...

[Q] Anyone able to share "AT&T Hot Spots" from their rom?

I'm trying to get at&t hot spots to work on a custom rom and the apk that I have I'm not sure if it is the right one I should be doing. Anyone able to put the apk on dropbox or something.
Justice bump. I asked this question a little while ago and never got a good answer. Out of curiousity what APK is it that you've got? I know digging through the processes it is listed as running in my phone. Replicating this would be great for ROMs, especially since I'm working part time at Starbucks....

This is what I tried using...
https://www.dropbox.com/s/fc68tce5vdvyayk/att_hotspots.apk
It shows up as a running app but it doesn't do anything. I'm going to check my bosses phone (S4) tomorrow to see how the app opens when I open it on his phone. On my phone, the app keeps saying there is an update when I select it but it never updates.
I agree that it would be great to get this working. A colleague mentioned that he was able to by both installing the apk and copying the apk to \system\app (for auto running). So far no luck on my end
This is different than the one that I had tried and looks to be the right one. I downloaded it to my SD card and went to install and got a message saying it was already installed as a system app (makes sense for stock). Have you tried doing it from there to keep functionality of it when flashing ROMs? I would say this is the right track alright.
Is your custom rom AOSP-based? Because I think I remember reading that the functionality of "AT&T hot spots" is built into the framework for touchwiz roms.
It is. I havent been able to find confirmation either way. Just that the hot spots app is what makes the connection.

First things first you have to make sure your kernel supports wifi tethering, without this you are wasting your time. In all my time on android as long as tethering is enabled in the kernel its just a matter of turning on the hotspot from within the settings menu. I don't recall the touchwiz menus to tell you exactly where the tethering option is but in aosp based roms its under the 'more' option in the wireless and networks section. This is also where you can set the ssid, security encryption, etc for the wireless network you are broadcasting.
Hi. It's not wifi tethering that I'm after. I want to use the AT&T wifi service that my office building gets since my cell signal is terrible at work. It's the only thing I miss from the Samsung ROM
OK so I flashed a ROM and tried installing the apk you were using and it seems to have made a small difference. I'm automatically connected without signing in to Starbucks AT&T WiFi (the way I would usually have to without the app) after having saved the network. Strange thing is looking at the app itself seems to suggest its not running. Running Apps shows 0.00kb in data. I'm not sure if its then a function of the ROM (which I doubt, its never done this before) or the app.

4.4 no mobile connection? no baseband? no IMEI? solution

It's been said a few times that SELinux settings have an effect on mobile connection on some phones, not all, but some. Mine being one of them, that theory has also been criticized, ironically by those who's phones do not suffer from the issue. Anyways, if your trying a 4.4 ROM and have no APNs, no baseband, IMEI etc grab SELinux mode changer from the market, set to Permissive and be on your way. Why or what causes it is beyond me but changing to Permissive solves it. It takes a few seconds after boot for supersu permissions, a few seconds then for your APNs to be populated and baseband, after that you will get mobile connection working.
Hope this helps someone else fighting the same issues. Here's a video showing before and after, a little wait at the APN screen the second time for them to be populated. Also, sorry for the quality, just easier to record the screen directly compared to holding a camera.

Glad it was of help, just passing on what I have read and tried to make it easier to find so made a thread for it, some of us have the issue but appears the majority do not.
I had the issue initially when installed with twrp, did it once again with cwm, worked like a charm. Good info to keep in mind though.
anybody got the apk handy they can upload? flashed the latest cm nightly not knowing it was 4.4.1, and the store won't connect via wifi for whatever reason.. i'd rather not have to do a clean install to get my phone working again.
Thanks.
Nevermind, I managed to pull it from the woman's unrooted moto x. It's here if anyone else needs it..

just out of curiosity. vAre you guys having any issues with the AOSP roms slowing down the data speeds? I know people have said for a long time since GB I think that the tw roms are much faster than AOSP I never saw that on HSPA+ but I am on simple moble and they just turnrd on their LTE and my phone gets an average of 28 down and 14 up. on tw roms but on AOKP or other AOSP roms it gets 8 up and 3 down. Like the lte is not working. Anyone else have these problems?
I love you.

Thanks, you have saved me the headache of reverting back to stock and the time it would take to start all over from scratch. .
man i wish i knew this eariler. i wouldnt have gone stock then back to 4.4. thanks for the info!
Thanks finally found solution to my problem it was only happening to me with 4.4 PAC ROMs

WiFi connection issue

So we have two smt310's in our household. Both will connect to our sky router individually but when I try to connect both at the same time they end up kicking each other off the network! I've tried with dynamic and static ip's but still the same result?
One tab is running slimkat and the other cyanogenmod (both were running CM but I installed a different firmware in case, for some reason the firmware's were conflicting with one another).... I'm at a loss, any ideas guys? It's proper doing my head in!! ?

hi,
on just a quick search, the idea of spoofing your mac address may be what you need, check this thread
http://forum.xda-developers.com/showthread.php?t=2286440
alternately an approach by modifying your kernel might work, more intensive though
http://forum.xda-developers.com/showthread.php?t=1878506
also maybe download and install from fdroid an app called network discovery.
after install , first launch will prompt you to update NIC database, do so.
then run scan to find your modem and paste that address in your browser to access and modify/maintain
your modem from your tab. Not an intuitive setup so have a look at the app's config and adjust as needed.

Wow, cheers! A lot of things to try there, I never came across then when Google-ing! Good effort ??

Bloody nice one @moonbutt74 it was my mac code, unfortunately flashing the kernel just left me with a bootloop so I tried to just delete the efs/wifi/mac_info file. Rebooted and low and behold my mac address was different and all the tablets now connect to the network at the same time!!!! Thanks so much for your help, I don't think I would have thought of changing the mac address! #legend
