downgrade from VRALG2 to 1 - Verizon Samsung Galaxy S III

I upgraded through odin from VRALG2 to VRALG1, just wanted to know if it's possible to downgrade back to 2 if i ever choose to and how would i do this? i am rooted and have the bootloader unlocked. thanks.

Get the lf2 file and update the same way you flashed lg1. You're just flashing radios so shouldn't affect anything else.

Odin the stock VRALF2.tar...click link in sig for instructions.

thank you for your quick replies. so far my s3 is fine after a day with VRALG1, no signal issues, might be improved actually, but just in case i wanted to ask.

Glad you made this thread. I was holding off updating my vrlf2 radio as well. Thanks this helped me too. Still scared to flash it though haha

so vral1 is better than 2?

I found it to be better for me but reading it sounds like depending on where you live might matter...

it is scary but as long as you can downgrade then you are okay. where i live i have solid 3g/4g coverage for miles and miles but i do notice a small difference, and i think my wifi connection is more solid as well.

[Q] Keep new firmware but use old modem/rpm?

I have a rooted/unlocked bootloader with the stock Touchwiz ROM on my phone, and since we're all having problems with the slow LTE speeds, I was wondering if I would be able to flash the modem/radio from the MD1 or KL3 onto my phone for better signal/speeds?

You can flash them, but it may or may not break some features especially if you flash an AIO (All In One)
Thanks! I'll have to dig around here and see what I can find

This worked for me, but it took a few tries. The first couple times gps got screwed up. I ended up doing a factory reset, then odin flashed back to mb1 (unrooting) . Then I let it update, rooted again with the md3 bootchain and then flashed the mb1 firmware. Happy to say Gps lock is instant and I'm back to normal 4g sppeds
Screw you Verizon!!! Why should we have to fix something you broke!

You might also consider some of the custom TW ROMS that have all the OTA has to offer and more with better stability. Synergy, Hyperdrive and MOAR come to mind, but there are others as well in the development section.
I took the update the other day, but I flashed the previous one a few days ago.works fine

[Q] If I have VRBMB1 can I flash a rom that is VRBMF1?

Sorry, I'm a total noob. I don't really understand how the "Baseband Version" factors into the ROM/phone operation. Can someone explain it? I have a pretty good understanding of computers but when it comes to the phone it seems very black-boxy -- I'm still learning. My underlying question is:
The BoneStock ROM says: "BoneStock v3.0 (VRBMF1) 6/23/13", my phone currently has VRBMB1. Can I flash the BoneStock ROM on my phone or do I need to upgrade the Baseband Version somehow before I do that? I saw links to different revisions on the BoneStock thread but there isn't a whole lot of explanation about how to use them.
Thanks,
-Greg
Yes No problems. I ran mb1 on bonestock.

Cool, do you know what the Baseband firmware does? Should I flash my firmware to VRBMF1?
I flashed mine mf1 because it really did help signal and data speeds. In my opinion it is worth it to flash the mf1

Did you flash it before flashing BoneStock or does it matter what the order is?
Modem has no relation to what ROM you are on. You can flash whichever you want first, doesn't matter.

[Q] Wedged SCH-I535

Hi,
I just got my 4.3 update on the VZW SCH-I535 phone! Then I decided to try CM10.2 and didn't realize that my phone was re-locked because of the OTA update! Now my phone is stuck with the message "System software not authorized ..." To move past this issue, I have tried (and failed) the following:
- Tried to flash stock rom using ODIN (withSamsung-Updates.com-SCH-I535_VZW_1_20120705143513_fti2qg2lmf-stock-rom-4.0.3). It goes all the way through and I get a PASS! But after the phone reboots I get the "System error ... " again
- Tried to flash stock rom using ODIN with stock.vzw_root66.tar file and got the same result as above.
- I have also tried installing with Nand Erase All and Re-Partition checked, with PDA selected using the first rom, but I still get the same error
- I have read and tried some of the thread on this site with no luck either.
Any clue how I can get past this issue? Thanks for all your help in advance.

Yup, I took the OTA. Didn't realize that it would un-root. I have tried various things at this point to get it back, but nothing has worked so far. Now when I try to use ODIN to do a CF-Auto-root, i see the "Secure Check Fail: recovery", at the Downloading screen. Any suggestions?
Thanks.
To my knowlage I am the only one hosting the tar file you need. Samsung updates doesn't have it because the file hasn't been officially released other than ota. If this dosnt work for you try flashing the pit file with the tar. It is one of the last replys in this thread.

Turns out, after working with the ATT folks for a while, that the IMEI number that my phone has comes up incorrectly in their database. It shows up as a Samsung Tab. Checked with Samsung and my IMEI number is correct, so ATT will have to fix it on their end to get my phone to work correctly. I don't know why they make it so hard to migrate phones across service providers.
I've got my phone bugging to update but I haven't done it yet because I don't want to lose root. if I understand this right I can update and then re root with that download? or is there another method?

The only working root method is currently saferoot if you take the OTA. Personally I wouldn't take it. I'd suggest keeping your unlocked bootloader in tact and running a custom 4.3 rom.

You van root 4.3 after ota or that link, but if I was you I would try to use the ota first. If it works you will keep all installed apps and settings (but it might be buggy). If you follow that link you will loose current setup, apps and it will format internal sd (but it will be clean and hopefully bug free ). Make sure you are home with access to a pc before you try ota. If you changed to much of the workings of your phone the ota may not work or could even brick you. In that case you will need to use that link.

Honestly I'm glad I took the ota on accident. The past few weeks my phone has worked without a hitch. Some people just do not need custom ROMs and I think I am one of them. I'm pretty sure everyone who complains about how 4.3 is buggy and a battery hog just needs to use Odin to get a clean fresh start. I am disappointed that I can't install cyanogen when I turn this into my mp3 player after I get a new phone but its not like tw is bad. It just has a few annoying things that I can change with root access.
Off topic
I dnt hate tw ..I think is a good Rom in general .all that bloatware what got me to root and then lead to custom roms .like mention not everyone needs cuztom things.I do agree that a clean install of TW runs great .but I like options .and to each there own

That's good. I've seen the OTA in action as my girl has it on her phone and she's complained about it every day since she took it. I've running wicked sensations 4.3 and it runs like a champ.

OK I just installed safestrap and I kid you not the theme of wicked sensation made me swap back to my stock slot immediately. I'll use it all day tomorrow and tell you what differences I notice. Right off the bat it just looks like a ROM made from a recovery backup and customized with xposed. I can't wait for beans to make a 4.3 rom.

Seriously? They put a ton of work into theme on this rom. I've seen 4.3 stock and I'm not impressed. It's boring and pretty basic. Wicked is an awesome rom. I've run just about all of them. Beans rom isn't bad at all but I seemed to have a ton of issues with it

I like it, but it certainly doesn't have quite the same cleanliness as a good AOSP theme. It's all personal preference.
At least we know safestrap is working consistently.

[Q] Keep losing network connectivity

I have a Verizon GS3 and had Clean Rom 6 installed for over a year with no problems. Last week I decided to flash to Clean Rom 8 and often during the day at random times I'd all of a sudden have no network coverage - 1x, 3g, or 4g. The only thing that would get it back was putting it in Airplane mode and then taking it out. I wasn't sure if it was the Rom so I flashed today to the SlimKat Rom based off of Kit Kat and i'm having the same problems. Is there something with my radio/antenna that i needed to do as well? Like i said i had zero problems with this before I moved to a new Rom last week.
Thanks

Make sure you're on the mf1 aio, then flash the ml1 modem. Should fix your issues with cleanrom 8.

Poor cellular signal on new 4.4.4 Gummy

Long story short.
Was running a 4.1.2 which worked well but wanted to go to KK.
Installed Gummy M3 4.4.4, absolutely love it, no issues except cell signal seems considerably worse than before. Baseband is VRBLMD3.
Not sure if firmware/baseband is accurate for 4.4 or if there's something I can flash to try and rectify. A little confused overall on the whole verizon modem thing. I had a captivate on ATT before and I just flashed any of the 30 different modems via recovery to help with signal issues.
Would appreciate any help.
I've read more than one topic on this same issue. Not sure what the solution is however. Maybe update the modem to something new? I wouldn't go beyond ML1 however

Flash mf1 aio then ml1 modem. Should give a better signal.
All the links to newer modems appear to be dead. I looked around quite a bit. I'd be grateful if someone can provide a dropbox link or similar.
Edit: It appears invisiblek's site is down and that's where all the AIO packages are linked to. Does anyone have any links to other mirrors?
