Hello everybody
I have a few questions regarding my phone and I hope you can help me solve them. I have the VS985 and I had it on 35b Lollipop 5.1.1 I was able to root it but then I realized there's no custom recovery for it yet, I was planning to try skydragon, so I downgraded using the TOT method to 10, so far so good, nonetheless, in order for me to try to install that ROM I read that I had to have the 35b boostack, so I installed the xdabbeb_vs98535b_bootstack.zip file, TWRP 2.8.7.0 says that installs successfully, I restart the phone but when I go to baseband says unknown and sure enough I can't install skydragon or cm13 because it says I don't have the 35b baseband.
I've tried the 24b, 23c and 12b modems, all get me baseband unknown and get no signal on Tmobile. The TOT I used was LG G3 VS985 10B_03 Stock TOT. I've been looking online and everybody says just flash the baseband on TWRP and voila! but not my case, I can flash it but doesn't work.
Any help is very much appreciated. Thank you.
Hello!
It is incorrect that you have to have the 35B bootstack to be on SkyDragon (same with JasmineROM). The only time it's a must is if you want to use Advanced Calling, or just plain want to use the latest modem. SkyDragon and JasmineROM contain several partitions from 24B. Flashing the ROM after the bootstack is what caused the issue, because critical partitions in the 35B bootstack were overwritten by their 24B counterparts that are in the ROM.
If you want the 35B bootstack, then you need to flash that after having flashed SkyDragon.

Hello there!
So let me explain a bit more about my situation, I currently have 4.4.2 stock 10b I downgraded from 35b 5.1.1. I rooted the phone and installed TWRP but when I try to flash CM 12.1 or CM 13, I mentioned skydragon but my mistake is CM what I want to flash, I always get the error that the modem isn't the right one, I've tried with several modems and same error. What can I do install CM?
Thank you

Either flash the 23C or 24B modem before flashing CM12.1/13. The 24B bootstack contains the 24B modem so you can flash that before trying to flash CM.
Edit: I haven't tried CM12.1 in a long time, and I've never tried CM13 so this is based only on old information which was definitely true at one time, at least for CM12.1. Repeat, no personal experience with CM13. I only chimed in at the mention of SkyDragon.

Hey there!
Thank you for your help! Well this I what I've tried, I restored to 10b using TOT I installed all modems, 12b, 23c, 24b and 35b and all of them are giving me unknown baseband afterwards, I get no signal, so I figured I'll install CM on top, but guess what? it always gives me the error that the baseband isn't the right one. I'm not trying to restore to 10b by using the KDZ method and then I'll install the modem. I don't know what is going on.
Thank you for helping on this.
P.D. I'll try skydragon to see what happens, I didn't install it because I read gives no data on Tmobile.

Hello! I have an update
So this is what I did, I downloaded SkyDragon V6.0.2 and installed on the 10b vesion and it worked just fine, I didn't want to risk to try to flash CM anymore but so far everything is working! even data on roaming, I'm currently in Canada and the Telus network is flying, over 70mb on download, as a matter of fact, I never seen those speeds in the US, at least where I live.
I'm sure if I flash CM from TWRP it will work because I'm using the 35b baseband.
Thank you all for your help!
Merry Christmas and Happy 2016!

Cool, glad you got what you need. You're welcome!
HAPPY NEW YEAR!
I'm rooted but on 100% stock 23C OTA software. What steps do I take to flash this this 35B ROM?
I apologize... I haven't flashed anything in a while.
I do have a custom recovery (TWRP v2.8.7.0) installed.
You have the same question posted here.

Hello, I am currently on a marshmellow rom (rooted) that has a few issues that I can't live with. I would like to downgrade to the latest stock lollipop rom (rooted). Is it my understanding that ZV8 is the latest stock rom? Also, does anyone forsee if I will run into any issues going from marshmellow to lollipop? Also, I did a search and found multiple ZV8 roms and I'm not sure which one to use. If anyone can link to the appropiate rom, would be greatly appreciated. Thanks
ZVC is the latest rom. However I don't have a link for it. You can however downgrade to ZVA and then upgrade to ZVB and ZVC after that.
http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/LS990ZVA_00.zip <-- ZVA tot
http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/LS990ZVA_00-LS990ZVB_00_update.zip <-- ZVA to ZVB
http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/LS990ZVB_00-LS990ZVC_00_update.zip <-- ZVB to ZVC
If you can find a direct link to the ZVC tot that would be easier.
Thanks for the reply. Can i just flash zvc from the marshmallow rom 6.0.1 or is it recommended to flash zva and zvb first?

You will need to downgrade using the tot method first.
I am about to root my LG G3 that's running VS98510B. It is unlocked, so will rooting it make the network limited to Verizon again?
Please in the future post questions in the Q&A section. I'll ask a moderator to move this thread.
All Verizon devices aren't SIM locked, and rooting doesn't affect that.
Just in case you don't already know, use the Stump app here on XDA to root using the brute force option, then use TWRP Manager from the Play Store to install TWRP. Rooting on higher than 10B gets more complicated, as does putting TWRP on higher than 12B.

Would it be okay to TWRP to flash VS98547A after I root?
Sorry for starting this thread in the wrong section.

Yes, you can flash any ROM you want. Just from TWRP, wipe Cache, Dalvik/ART and Data, flash @xdabbeb 's 47A stock pre-rooted firmware and his 35B Bootstack (the Bootstack is from his VS985 v2.0 ROM thread). Don't wipe after flashing the ROM or you could lose root, although if you do, you can dirty flash the ROM to get root back. There's also optional debloat zips in the third post of his 47A firmware thread if you like.
No problem mate!

That answer is in the thread I told you where the Bootstacks are.
As above, do I need to flash stock recovery and unroot my G5 to install Nougat via LGUP or can I stay on TWRP and flash V20a? I've tried to ask in dev thread but I couldn't because of my post count

When you flash a firmware with LGUp you lose TWRP and Root, so, it's the same.
Alright, thank you for quick reply I read somewhere that I need to return to stock recovery and unroot to flash V20a and I didn't know which way to flash is that proper way xD. Anyway, thank you ^^
