Question about ZV8 VS ZVA Radios

Hello,
I hope this question has not been asked before, if it has then please accept my apologies. I am currently rooted on the stock ZVA Rom that came with my phone and as most of you know there are alot of issues getting a 4G signal on this rom because of the ZVA radio that is installed by default and my questions are as follows:
1.) If I switch to the ZV8 radio will 4G work on my phone? (assuming I in a 4G area that is)
2.) Can I switch back and forth between the ZV8 & ZVA radios without to much fuss? (meaning what steps are involved assuming I am running stock rooted like I said before)
3.) Where can I find the above radio files so that I can flash them using TWRP? (I have found a couple of threads where they are listed but I am not sure if they are for stock roms or custom roms so I need the ones for a stock ZVA rom)
TIA,
Mtcell

1. Yes. ZVA is just the update for Spark. ZV7 and ZV8 both work with everything else including 4G, 3G, ect.
2. Not speaking from experience, but after reading about it it looks to be pretty easy. Just flashing what you want.

Thanks for the reply. The link you posted with the radios was the one I was talking about, but I was not sure if they were for custom ROMS or the stock rom and I did not want to install something that could potentially brick my device.
About the other 2 questions, has anyone actually switched back and forth between the 2 radios, if so what was your experience ?
TIA,
Mtcell

They're for both stock and AOSP based ROMs. The kernel is what is specific for stock and custom.
It seems dr87's kernal and Furnace now allow ZVA to be used on custom AOSP ROMs. Those are the ONLY kernels you can use for ZVA without bricking your device for custom ROMs. ZV8 still supports the other kernels. Most of the stock ROMs now support ZVA I believe without having to flash a kernel, but read the threads before doing anything.

In my experience its much easier and less worrying to just use the ZV8 radio. If you have spark in your area then its worth a shot but be very careful. If soft bricked my device but got it back up and running.

[q] lg g2 ls980 zvc roms??

I want to flash a custom rom to my LS980.
I have the new ZVC update, and have TWRP due to flashing the ZV8 Bootimg.
Is it now possible because I did this to flash Roms compatable with ZV8 and up?
I have a .tot file, but would rather not have to go thru that again..

[Q] Galaxy S3 - T999L Bootloader and Baeband Help

I may have just figured out my problem with signal but I want to run it by you masterminds first... Looking in the cyanide about phone exta info I see I am using bootloader T999LUVAMB7 and I flashed the NC1 modem a few days ago and ever since had poor reception... I'm thinking its cuz the bootloader doesn't match the modem... now there is OFW AMB7 , BMK4, BNC1, and BNF4 all in order of release date NF4 being the latest aug 2014. now since my bootloader is the oldest version and my modem is the 3rd update of 4 possible... should I Flash the complete BNF4 OFW and MODEM to update my bootloader and baseband modem to the latest and then flash Custom recovery / root / flash Cyanide L 5.0 (kernals gapps all that) ??? and if so should I backup or store anything on the way so that I can revert back if needed?? what would be the smartest play here? I don't want to brick my phone. I had originally upgraded to Kitkat 4.4.4 and cyanogenmod then went to cyanide lolipop ver 5.0.2 I dunno if this makes any difference or if all that matters is my current bootloader and basebands.. but I know the secure bootloader worries me so I don't know what to do exactly. I am fairly new to this still...
Thanks guys!!!

You'll need to flash the bootloader & modem together, if you're on NC1 baseband you should flash the NC1 bootloader & modem.zip so they match, however I'm not exactly sure about skipping versions, I've heard that you should do it incrementally not skipping versions, when I updated mine (d2att) I didn't skip. You're lucky as heck you didn't brick it already, now that you've skipped & are on NC1 baseband and the phone still works I (THINK) you'll be OK to flash the NC1 bootloader & modem.zip while on cyanide. Do it at your own risk, I'm just trying to help, look into it & search, talk to others as well & be sure!! Good luck, hope you get it going!

If you take full NC1 = Locked
Is that correct? I kept a early bootloader and get update-binary erros in cwm. My flashes have continued just fine thru to Carbon KitKat (TWRP/CWM/Pref - Philz Touch). The Modem is the Safest Thing I flash.!. The last time I took the latest firmware BEFORE 4.3 And Flashed it in Odin. I have a frantic mind. I anticipte some issues with kernel and "drivers" on Lollipop. Just what worked for me.
I know there are KNOX Free images, but I have not flashed those with Odin. Ufvthey say bootloader is unlocked or left out I might try one of those first. I am Probably being paranoid, but in my head it made safer sense.

Help With Grola

I want to try out Grola rom but i really dont want to go through the process of having to .tot just to go from that rom to another. Is there a way to flash another rom without having to .tot back to factory.? I have the ls980 variant

Read the directions very carefully. If it is aosp or cm variant. You need to flash the zv8 radio after the ROM.
Primary thing, make a backup first. If you have newest TWRP, it will backup radio. So when you recover you can have no issues.
If it is stock based no problem. You only have to tot if you really needed something up or going back to zvd or zve radio.

Ok so i just boot into recovery, flash correct radio and flash the new rom i want. Unless its a zvd or zve stock based rom then i would have to .tot right.?

Right now I'm on resurrection remix. Which is cm based. So I have already downgraded boot loader by getting TWRP installed. I flashed zv8 radio for the ROM. If I wanted to go back to stock based because I didn't backup my radio. I would tot.
This way my radio is back to what it needs to be.
Or if I screw something up on flashing I can tot.

[Q] Upgrading baseband version

I'm using SlimKat 4.4.4, yet my phone's baseband version is 4.1.1 (I747UCDLK3). I'm looking to upgrade my baseband version to 4.4.2 due to some issues.
Can I upgrade straight from 4.1.1 to 4.4.2?
Or do I need to upgrade to 4.1.2 -> 4.3 -> 4.4.2? If this is the case, I have one concern. There are many footnotes saying if you downgrade from 4.4.2 to a lower version, you will brick your phone. These footnotes don't specifically say whether they're talking about OS version or baseband version. Is it safe for me to upgrade to 4.1.2 -> 4.3 -> 4.4.2 with a 4.4.2 ROM? Is it safe for me to flash a 4.1.1 stock ROM?
Any help appreciated. Thanks!

first if wanted , i would get the free unlock sim code (am pretty sure is available on 4.1.1).
all i have ever read says to do the incremental updates (safest).; which i believe you can do OTA ; or flash thru recovery.
yes , you will most surely brick your phone if you try to downgrade bootloader from 4.4.2.
AND you want to keep bootloader and baseband at the same version. upgrade one then upgrade the other.
if your already on 4.1.1 , then yes flash away the stock 4.1.1 rom ; if youre talking about after you upgrade to 4.4.2 then the 4.1.1 may not flash unless you edit the updater script (think thats what its called , been awhile).
good luck !

This is an I747, right? I think the I747M had LK3 firmware too. If you happen to be on an I747M don't flash any of the I747 specific stuff below, or you'll probably brick your phone.
Since you're still on the old firmware it might be a good idea to carrier unlock your phone if you haven't already done it. You'll lose that ability if you update.
To update to 4.4.2 firmware you can go two ways. You can Odin back to unrooted stock and you should start receiving OTA updates. They will be incremental and they'll come about 24 hours apart, or you can set your system time ahead a day to cheat that. Eventually you'll get up to the 4.4.2 firmware. NE4 is 4.4.2, but NJ1 is the most recent. This is probably the safest way, but it will be somewhat slower. Those OTA's are full firmware packages so they're big downloads.
Or you can flash bootloader/modem only upgrades in custom recovery. Enewman17 has posted everything you need to get an I747 up to date to XDA. I flashed all these while running the Slimkat stable 9 ROM to get my I747 from LK3 up to NJ1. This has to be done incrementally and you have to boot successfully into your ROM in between each firmware flash. You can't jump from the 4.1.1 bootloader to the 4.4.2 bootloader. First flash the MJB firmware update linked to this thread then reboot into your ROM. Next flash the NE4 firmware zip also linked to that thread and then reboot into your ROM. You're on 4.4.2 firmware at this point, but if you want to be on the newest bootloader and modem then flash the NJ1 zip attached to this thread. If you go this route be sure you read enewman's posts very carefully and understand exactly what you're doing because fiddling with the bootloader and modem is the #1 way to hard brick this phone.
For the most part you can flash any ROM you want no matter what firmware you're on as long as it is intended for I747. You might find that your wifi won't work or your modem doesn't work or maybe it just bootloops if you get on a ROM that wasn't intended for the bootloader/modem currently on your phone, but you can still boot up into recovery and restore a backup or flash another ROM and get out of that. What you have to be very, very careful with is the bootloaders since Knox was introduced, that's MJB, NE4, and NJ1. Those bootloaders cannot ever be downgraded; don't try it. You'll hard brick and it is pretty hard to recover from. Its also for the best to keep your bootloader and modem matched on this newer firmware; the OTA method or the zips linked to the threads above will do that. Custom ROMs that are AOSP/CM based won't ever mess with your bootloader and modem. They're just a system image and a kernel. What you have to be really careful with is Odin, those are usually full firmware packages. AT&T hasn't allowed a stock image beyond 4.1.1 to be released for the I747, so once you're on the newer bootloaders there is no more option to Odin back to stock.
Good luck.
