[G3 Q&A, Help & Troubleshooting] Abu Siona:
Did you try to boot it to see if GSM was working even though those two are failing?
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Also, the phone now boots into MiniOS-ATT-Test Tool and appears to be a D851 now. I am super confused as I have been noticing that on the back of the phone it has D851 written on it too along with US990. Do you think I should try flashing D851 partitions instead of LS990?
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Yeah the mini os. Forgot about that one. After it boots to mini push and hold the power button. then after the first test passes scroll down a bit and select normal boot while still holding the power button.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
As far as flashing back to US990 goes, you would need to flash a US990 nandroid and maybe some of the partitions to get flashtool to see the phone as a US990. Right now you may be able to flash the LS990ZV4 KDZ and then proceed to install cloudy.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
the D851 is only on some of the parts because LG uses them in different models. I flashed D851 modems to the phone and none worked. The phone lost baseband and I had to flash it back to an LS990 Modem.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
I am now running Cloudy as LS990 but "mobile networks" is still grayed out. I don't know what's wrong. Shall I restore I back to LS990 stock and then flash Cloudy again? Shall I flash Cloudy with boot.img or without boot.img?
[G3 Q&A, Help & Troubleshooting] Abu Siona:
if you flashed cloudy while you were still a US990 then you needed to flash without boot, but if you flashed cloudy after flashing the LS990 partitions then you want to flash cloudy with the boot image. Did you flash the LS990 ZV4 modem in fastboot? And Is your baseband showing in the about/network info? if you baseband is not showing then that is why you have no network. If this is the case then try to flash the LS990 Zv4 kdz and then install cloudy again with the boot image.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Thanks for explaining. I Just flashed Vanir ROM. Will try flashing ZV4 Modem in fast boot though I can remember seeing Baseband Info available in their.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Does Vanir Rom work with GSm on the LS990? I used cloudy because it has the GSM option for the LS990. It looks like CM12.1 also has the GSM enabled for the LS990 but it does not look stable yet.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Nope! Vanir ROM freezes at boot. I'm lost and almost giving up. Right now I'm this:

No Access to fastboot.

Phone boots into LG Security Error

Can't restore to stock either using LS990 or US990 kdz - LG Flash Tool won't detect phone anymore.

I accidentally flashed stock recovery and now I'm on stock recovery.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
If you try using flash tool to flash the LS990 tot then make sure your phone is using COM41. Your PC may have changed the port number or you may just need to set it to COM41.

I am not sure where the security error is coming from but maybe it is because of the stock recovery and the custom rom being together on the phone.

if you can somehow get back into fastboot then you can flash TWRP using the fastboot command: fastboot flash recovery "name of recovery file". from there you can install cloudy again or restore a nandroid to get you back into working condition.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
It's now detected in LG Flash Tool but won't restore either to US990 or LS990, says model info can't be retrieved at 6% when it's looking for LAF. Hahaha.

I'm trying to figure out how to get in to fastboot. I think the security error is because of the stock recovery. Do you know if there is a way to restore to stock ROM from stock recovery using adb sideload or something?
[G3 Q&A, Help & Troubleshooting] Abu Siona:
i was thinking of using the stock recovery too but I never had to do it so I don't know how to make the zip to send using sideload. it would need to be properly signed anyway. I don't think the stock recovery will flash it without it being signed.

I am also thinking the Vanir ROM broke your partition table. I had the same issue when I tried to flash a lollipop rom. It would corrupt my system partition every time I tried to flash one. So not that rom specifically but because it was lollipop.

Without the custom recovery, i can not think of a way to get you fixed.

I assume you deleted the laf and then put it back at some point? maybe you have mixed partitions on the phone. Flashtool should see it as either an LS990 or a US990 but you say that you can not flash the LS990 tot or the US990 KDZ.

I am stuck.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
That's exactly what happened.I flashed laf from ZV4 and the partition table is broken. Only way I can see out of the situation now is to flash stock using adb sideload. I give up for now!

Thanks a lot for all your help anyways!

To add: Now, I lost access to stock recovery as well! *sigh*
[G3 Q&A, Help & Troubleshooting] Abu Siona:
If I think of/run into something, I will post it here.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Cool, thanks!

Do you think you might have a DLL and TOT for US990? I tried extracting from the kdz but it won't work and I get Failed to Load error in LG Flash tool 1.8 while LG Flash Tools 2014 just does not recognize my phone anymore, maybe I need to try doing it on another PC or re-image my system. :mad:
[G3 Q&A, Help & Troubleshooting] Abu Siona:
No. I do not have a tot for the US990. Only the KDZ.

Have you tried using a different USB port on your PC or uninstalling the LG drivers then re-install? I am sure you have restarted your pc a few times too just to see if the phone can reconnect to LG flash tools. You could try changing the COM port to see if that helps Tools see the phone. It is strange that Flash tools can see it but not Flash tools 2014.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Done all that! Apparently Flash Tools 2014 is encountering the same error but not displaying the error. And with Flash Tools 1.8, I can only flash LS990 which gives partition change 00000064 error at 6%. I tried extracting .dz and dll for US990 from the kdz but get Failed in Previous Load error on Flash Tool 1.8

I think this device is now hard bricked. :(
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Did you use this extraction tool?

http://xdaforums.com/showthread.php?t=2600575

I was able to extract the kdz and DZ and merge the system partition that should be flash-able through Flash tool.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
I used the same tool but don't really understand how to merge the system partition?
[G3 Q&A, Help & Troubleshooting] Abu Siona:
first you extracted the files from the KDZ. That gave you the DZ and DLL. then you should select the DZ using this same tool and it should populate the list with the bin files that are in the dz.

Extract all the files from the dz and then click on merge system-bin. The tool then creates a sub-folder named "merge_output". Inside is the system file. You should be able to flash that or maybe some of the other bins that were extracted using Flash tool just like you would flash a tot. I think I did this long ago with a VS920. Not sure about the model.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Flash tools also let me select he dz for flashing too. Did you try to flash the US990 DZ using the BOARD DL as the flash method?
[G3 Q&A, Help & Troubleshooting] texan_mirage:
I did that but the output is an .img file and LG Flash Tool 1.8 won't accept it.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Try to rename it to bin. Also try to flash any of the other bin files to see if you can get back running.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Yes done that to no help.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
You could try extracting the LS990 tot to see if flash tools will let you flash any of its individual bins.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
That sounds like an idea. I'll try that later tonight and post results here. i started a new thread in Q&A. Gotta get back to work tomorrow morning, so it might be delayed now. Spent 4 days straight with this, my head hurts now. Lol!

[G3 Q&A, Help & Troubleshooting] tyiphius:
So i ended up bricking one of my phones, I called LG and the person I spoke to lead me through a bunch of methods (a bunch off xda and teamuscellular). Any the guy told me I could send it in so they could fix it. The interesting part is that he told me they'd load sprint software on it then send it back to me and I'd have to send it to us cellular for them to put their software on. I'm going to call again tomorrow and see if i can get more info out of them =)
[G3 Q&A, Help & Troubleshooting] tyiphius:
This is probably a stupid question, but how do I delete the laf partition?
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Everyone seems to be bricking their phones. I really do not want this to happen again. maybe you should just let it go.
[G3 Q&A, Help & Troubleshooting] tyiphius:
Aww thats no fun =(

I don't mind. The phone I'm testing with now can't be activated on US Cellular anyway so I really don't care. I also bought an Octoplus box and it has a "direct unlock" option for the LS990 so I was curious to if that could unlock it. But I'd have to get on the LS990 software first. I installed couldy but i keep getting the "fastboot mode started" screen. Don't know how to delete the laf partition.

There's no support for the US990 with the Octoplus box and I've been trying to get in contact with them so I can try and get one of these phones to them so they can test away, and add support for it when they figure it out. =/
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Since you are in fastboot you should just flash the partitions that I listed. You should be good to go after that.
[G3 Q&A, Help & Troubleshooting] tyiphius:
Ok, So I restored your nandroid backup of the LS990. I used the octoplus box to direct unlock it as if it was a LS990, when through... Changed apn settings through an app and after a while I had LTE, it seemed to cut in and out a little but I used This app and changed the settings to one with GSM or LTE. I'm not getting calls or text to go through. In the app it says "GSM Service: Emergency calls only". The phone recognizes im on ATT, shows my sim card. I restored my nandroid backup of when I was on US cellular and now I'm getting lte on there. Still same results with calls and texts though. I even used Shortcut Master (lite), searched networklock, and turn the network lock mode to off. But still only data. Also with the Network app if the LTE/GSM/WCDMA option is chosen and you hit "turn off radio" under it. The mobile networks options become available via the settings menu.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Did you flash the ZV4 modem from the LS990 through fastboot? That has to be done or calls and text will not work.
[G3 Q&A, Help & Troubleshooting] tyiphius:
I just ran the flash.bat file in the ZV4 folder.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Where did you get the octopusbox from? I wanted to get one but can't really find any in the USA.
[G3 Q&A, Help & Troubleshooting] tyiphius:
Cellcorner

Ebay

Its the same guy. I went with ebay, and best offered 378.01 so it'd even out to 400 with shipping.

You could probably get a better deal than me. There are a lot of phones that can be directly unlocked with it. I've only had it for 2 days and havent used it much but its worth my money.

TIA!
[G3 Q&A, Help & Troubleshooting] essojay:
Btw, it doesnt look like the us990 is Quad band, it doesnt seem to have europe GSM band .. any opinion regading this will be appreciated.

[G3 Q&A, Help & Troubleshooting] Abu Siona:
The modem is in the ZV4 modem folder that I posting links to in this thread. i think you have it already.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Yeah, I figured that out. It's running the ZV4 modem but still won't register on any network. When I do a manual search it gives error as failed to search or not available.

I'm running Cloudy 1.3 and device is now LS990. Does your device has D851 written on the back panel anywhere?
[G3 Q&A, Help & Troubleshooting] Abu Siona:
Yes. it is printed on some of the antenna stickers. The D851 modem does not work at all. It will leave you with an unknown baseband if you flash it. I did that.

Which carrier are you trying to connect to?

Is the sim active?

Did you switch the network to GSM/WCDMA?

Did you flash the other ZV4 partitions that I mentioned in the earlier post?

if none of that works then you could try flashing the LS990 ZV4 tot and then install cloudy again.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Yes, the sim is active. I'm currently up north and am trying to connect to Rogers in Canada. I did switch the network to GSM/WCDMA.

I was able to flash all the partitions except "PrimaryGPT" and "rct" as they gave error: file size too big or partition table doesn't exist.

I was never able to restore the device to stock LS990 using LG Flash tool.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
That is strange. I was able to flash the LS990 tot with out an issue. Maybe the bands rogers is using are not working on that phone. The phone could be using only WCDMA bands.

Might be the same reason why it is not working in Europe.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Which networks have you tried in States and can confirm working? Also, the Bluetooth and Mac address is not availabel on my device.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
I have used both AT&T and T-Mobile to make calls and send text. Just no working data for either network. Bluetooth address does not show until bluetooth is turned on but he mac address should be there. Mine shows both when i have bluetooth on and only the wifi mac when bluetooth is off.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
ok. I don't know what I'm doing wrong but I never could restore the phone as LS990 using the LG flash tool.

I have decided to roll back to US990 and use the soft cdma unlock and dispose the device.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Ok, I am back home and tried connecting the converted US990 to GSM network in States. I can't connect to nay GSM network at all. My phone is a LS990(converted from US990) and is running Cloudy G3 1.2/BarePop v1orv2/ LG G3 LS990 Stock with variety of modems.

This concludes that the US990 device has no GSM capabilities and is a CDMA device only. I can easily connect to a CDMA network.
[G3 Q&A, Help & Troubleshooting] tyiphius:
The weird thing is That i've gotten LTE to work but had no calls/texts coming in. I've flashed and done a bunch of things with this phone, that I want to flash this phone back as a stock US990 and try again from scratch so I can log down everything I'm trying and what results i get. My only problem is that I dont know how to put my phone back into a stock us990.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
I returned my phone back to stock US990 and converted it to LS990 again and I am once again using it on AT&T.

To get it back to stock you will need to use the US990 KDZ but before you can flash the KDZ you will have to make flashtools think it is a US990 again.

If you made a nandroid back up of your stock US990 then restore that and then try to run the US990 KDZ through flashtool 2014. If you can not restore using flashtools 2014 after the nandroid restore then flash the separate US990 partitions through fastboot and then try the KDZ again.

autoprime has uploaded many useful files HERE.

You can find the US990 partitions that you need there.

I never got LTE to work except using a US cellular sim on the stock rom but I always get WCDMA working after the conversion.

GSM does NOT work on this converted phone. It is only working in WCDMA mode. If you use it in GSM/2G only mode then it does not connect to a network.

So with AT&T I get HSPA and with T-Mobile I get UMTS but neither has working data for me. Only calls and text.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
What's the pint in restoring it again to US990? I have the nandroid for US990 and I have prepared partitions using ImagePrep from stock roms for both.
[G3 Q&A, Help & Troubleshooting] Abu Siona:
The point is to log the steps and make sure you do everything correctly. I went back to stock because I bought an octoplus box and I wanted to see what it would do to the freshly converted LS990. The box unlocked it but did not allow data to work. Just like when i used the cloudy rom. So for me it was simply something to do. I am pretty sure that the GSM bands are disabled at the hardware level on the US990. I have done NV edits, used the octoplus box, flashed teh custom roms and modems from all the G3 models. All I can ever get is WCDMA. I have not been able to connect in 2G only. Which is what is needed for this to be a real GSM usable phone.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
Cool! I did the NV edit too but surprisingly, all the bands were already enabled. When I go to band selector using Shortcut Master, I can not see GSM 850 as an option. I even tried the standard unlock procedure for LS990 which made no difference. Unfortunately, I am not even able to use LTE or connect in WCDMA mode. Apparently, your hardware differs from mine.

Would you mind preparing a list of steps for the conversion and posting it here? I could help if you wanted.

Thanks!

Getting it back to stock on US990 is pretty simple. Flash the US990 partitions in fastboot mode and you will end up in MiniOS. Continue normal boot and you will be fine. If you get stuck, boot in to Download mode by restoring laf from US990 partitions and retsore using KDZ with Flash Tools 2014.

Next time, make a Nandroid backup for US990 and LS990 both and switching would be lot easier.

Also, if you ever fail to get to recovery, flash TWRP recovery for either LS990 or US990(depends on what you are doing) in fastboot and you will be good. You may want to use the oldest version of TWRP recovery available as newer versions always gave me a lot of trouble.
[G3 Q&A, Help & Troubleshooting] texan_mirage:
To add, I was able to get connected to GSM networks in WCDMA mode. I tried changing few properties using Build Prop(honestly can't remember what all I changed but actually just compared with my LS980) and it worked but with no data. Also, it won't work in Canada as LTE frequency used in Canada is different than here in States. I will still check again in Canada once I go working up North again.

[MENTION=6488483]Abu Siona[/MENTION] Thanks for all your support and keeping me motivated. :)

how to do again
[G3 Q&A, Help & Troubleshooting] Abu Siona:
You will need to delete your laf partition so you can get into fastboot mode.

Follow the instructions here:http://xdaforums.com/tmobile-lg-g3/general/how-to-boot-lg-g3-fastboot-mode-t3087445

If you are rooted just skip to step 5

Download the partition files from this link:http://xdaforums.com/showpost.php?p=60612370&postcount=11

DO NOT FLASH THE STOCK RECOVERY! Flash the partition files using the .bat file in fastboot mode then reboot and check if it is fixed. If not then flash cloudy again. If it is still not fixed after this then restore the phone to a stock LS990 ZV4 using the LS990 tot file and flashtools.

You have to use LS990 ZV4 or cloudy causes the unknown baseband.

I don't remember where I got the ZV4 tot file but I am sure you can find it here on XDA. After you flash the tot you may reboot into minios mode. To get out of minOS press and hold the power button before you touch the screen. After the first test you will get and option to reboot into normal mode. While still holding the power button click that option and it should reboot normally.

You will need to root, install TWRP and cloudy 1.2 again. This time install the LS990 TWRP since the phone will be an LS990 now.
[G3 Q&A, Help & Troubleshooting] Tech_Savvy:

[G3 Q&A, Help & Troubleshooting] Abu Siona:
No. There are other changes made to the system to allow GSM to work. The cloudy rom has the changes built into the rom and so it is the easiest way to get GSM on the LS990/US990. If you use another rom that is made for the LS990 that does not have GSM capabilities then you will have to do much more research to find out how to enable GSM.
