[Q] LS970ZV9 back to LS970ZV8

I have been hitting the install later for a couple days now and my daughter picked up my phone and installed it (9 years old told not to touch phone).
I have rooted my phone on V8 for Wi Fi tethering but now it does not work.
Can someone IM me the noob directions to revert back to the V8 or point me in the right direction if there is a noob version out there..
I have come across so many threads but you have to be a rocket scientist to understand them.
Need a noob dumbed down version on how to get back to V8 please

Can't go back to ZV8. Have to go back to ZV7 then re-unlock and re-root.

i think what op wants is to not have to lgnpst back to zv7 every time he softbricks.

I'm confused... does that mean once you get back to ZV7 the phone has to be rooted, then load the rooted ZV9 version, or once to ZV7 one has to update to ZV8 then re-root then load the rooted ZV9? Where does one fine ZV8?

pretty much. if you try to update i think it just goes straight to v9. i have yet to find v8 firmware anywhere except for a flashable zip which you need to be unlocked for anyways.

Re: Rooting software version zv9
PM me and i'll get you the instructions to downgrade and obtain root. Its rather easy. Cant post here due to the links being proprietary LG software I believe

Yes you can root zv9 on this link. Guide has instructions for rooting and unlocking zv9, it is a little bit further down but is there.

Or you could just flash the rooted version.

LG bootloop after unlock

A little help please? I can root ZV9 and ZVB but continue to have issues with installing a customer recovery. I get the bootloop on the LG logo. I can always get into download mode and fix it back to stock but no further than that. I must be missing something. Steps are as follows
1. Root my LGOG with fiddy619's ZV9 AND ZVB/JB Root zip. SuperSU and root checker say all is good
2. protect root with Voodoo OTA root keeper
3. Instal and run FreeGee from the play store (latest version 0.6.0.1). FreeGee congratulates me.
4. Install custom recovery and close FreeGee
5. Open up GooManager and update to newest TWRP 2.4.3.0
6. reboot to recovery (tried several methods, manual, reboot recovery from GooManager, QuickBoot)
7. cross all appendages and pray
8. LG bootloop
I can get back into download mode and fix it with LGNPST and rescue my phone to ZV9. So for me... root is easy just no recovery. Can TWRP be flashed from the stock recovery if I place the flashable TWRP zip in my cache folder?

Have you tried to LGNPST back to ZV7 then use the aio tool. It worked great for me.

I've used that I believe. I think that's what I used to recover from my bootloops. Then when I root that (I've tried several reboots with stock recovery and all is well), I get the bootloop after FreeGee and customer recovery even on ZV9

Irc has it. Same place you find LGNPST. They have a link for the file.

Same boat over here, root and unlock on v7 and get bootloop, then restore. Then root and unlock on v9 and get the same thing and have to restore. Everytime i install the recovery and unlock, i get the lg logo and a black screen. Hope someone can help

Can't get in to recovery, just get the lg logo, then a black screen. Or restarting the phone after unlocking with freegee, then get th lg and black screen. Had restore with lgnst to work again.

Maybe zvb has the same problem of before where certain people just aren't able to unlock with the regular freegee for some reason. Shelnutt made a special version for ICS so I would ask him if he has one for jb.

LG FlashTool Issue

So I bought an LG Optimus G last week, attempted to root and flash a rom but missed a step and now it's bricked. I can get it into download mode and I have the LG FlashTool as well as the .dll and .tot The only issue is it says I have the phone model lg-e971 so it gives me a FAIL. From what I've read its because I already have the zvc.tot on it so I have to revert back to the zvb.tot and then back to the zvc.tot correct?? If so, where do I find the zvb.tot to flash on there. I haven't been able to find it anywhere. If anyone happens to have a link to that .tot or can upload it for me that'd be much appreciated.

Did you flash an International version instead of a Sprint?
The .tot is the same as the .bin. Just use the dll that came with Flashtool. The bin is in the root guide.

E971 is the Canadian version of the OG. You or someone tried to install a Canadian ROM. The DLL you have is for the Sprint version. That's why you have the conflict.
Probably try to use LGNPST instead. Links for it are in the irc, and the teeny bin thread under Additional info.

I do have a sprint phone. Its just that I rooted it, then unlocked the bootloader and I guess I apparently missed a step somewhere because when I started it back up it just showed the LG screen and went black and so I assume that's it being bricked.

OK. Just checking.
Have you tried to get into recovery? If/ when you do, you'll probably need to do a factory reset.
Also, instead of the bin file, you may be able to use teeny bin.
And you shouldn't need to go back to zvb.
Sent from my LG-LS970 using XDA Premium 4 mobile app

It won't let me get into recovery, it'll only let me do the usb mode when I plug the usb in. otherwise it just shows the lg screen for half a second and then goes black till it kills my battery. If I hold down the power button for a few seconds and let go, it turns off but then boots back up and does it all over again.

Awesome!!!!!! Downloaded LGNPST and set it up (it was somewhat tricky like they said) but once I got it down I know what to do. Anyway I flashed the teenybin file to have the bootloader unlocked and custom recovery and I was able to reformat everything. Thanks a bunch. Maybe this thread will be of help to someone else along the way.

No OS, cant access download mode. HELP!

This is my first post, so I will be as clear as I can. I rooted my LG OG with no problem, then made the mistake on trying to unlock it using freegee. When I tried to reboot, it got stuck with a black screen. Then affter doing some research, I used LGNPST to see if that would work. When it reached 85% and rebooted, only got to the 4Glte screen and quit. Tried to reboot several times to no avail. I then tried to use the TINYBIT for my lg970. Now I am stuck with twrp 2.4.4.0 and no OS. I can only access fastboot and recovery. No download mode! I cant even flash a rom, cause when I try and push one to twrp using adb, it fails saying cant find partition. Any help would be excellent! Don't be afraid to tell me it is bricked.

This is a no go.
Background:
Buddy was rooting his phone and thought his build was OB7 but apparently it is OE1. He loaded up TWRP (wiped everything w/out backing up) tried to flash a custom ROM, no go (it boot loops). He then tried to ODIN back OB7, no go, fails.
I searched for him and found a backup nandroid [email protected] . I inserted it in the TWRP folder and under backups and tried to restore, no go.
Question:
Is he stuck until and OE1 tar is available?
