Bell E973 running E97310H downgrade possible?

I've rooted my phone and tried several rom's until I noticed 10H can't install any custom roms. Am I stuck running the stock ICS rom or is there a downgrade method possible?

You can flash any LG based roms like the E975 JB roms.
The ones you can't flash are the CM, AOKP and AOSP based roms.
But yes you have to downgrade to the original ICS rom in order to be able to flash all roms.

I've been searching threads and can't find any old kdz files to use for downgrading. Know where I could find em? Also, would you be able to show me a link of a rom I can flash without downgrading?
Thank you for the quick reply.
I'm assuming you mean something like this one: http://forum.xda-developers.com/showthread.php?t=2127346 it doesn't work. I get the same black screen after initial logo like all other roms. Only way to restore phone is via KDZ restore.

After flashing, do a factory reset in recovery. Then see if it boots.

Steps that I do are before flashing:
Factory Reset
Wipe Cache
Wipe Davlik
Wipe System
Wipe Data
Tried once doin an F/R after flash. Still same thing. 2 Ways to do F/R right? Via recovery and by holding down the power + vol down? I've done it via recovery only thus far.

If you have custom recovery then you can only do it in recovery. The other method is if only if you don't have custom recovery.
Maybe your downloads are corrupt.
Either way you can try downgrading once you find the old kdz.

Sorry I realize this is old, but i always figured e97310h was the oldest one for my sasktel phone that I could flash to, but I was able to find older KDZ files from this site, i hope I can link it for you. Good luck.

Safest way back to stock

Hi guys, I have european e975 and would like to go safely back to stock, but i need help.
I tried to flash the new V20A stock KDZ via vietnamese easy method http://forum.xda-developers.com/showthread.php?t=2797190, but the tool just can't connect to the device, i tried everything, even fidling with COM ports.
Also I made backup with TWRP of V10H, but now the phone has CWM and CM11 and i don't know if i should use the backup.
tl;dr: Safest way/method to flash back to stock?
ThankYou )

Try to flash TWRP again, then restore backup

Flashing the twrp backup is fine don't worry.

[q] help! Lg g2 sprint!

Ok so my LG G2 was on ZVC, I flashed ZV8 Radio then tried to flash CM 11 to it and the rom failed then I tried to use my backup but I was stuck in a bootloop because I think the radio is still there, then out of desperation and looking at 1000 different forums I wiped the data completely and now I am just sitting here on recovery not sure what to do.. any help would be awesome :good:

if you can get to download mode, i would just tot to ZVC

Are you familiar with the LG Flash Tool? That would get you unstuck and back to stock. Check this post: http://forum.xda-developers.com/showthread.php?t=2656275

[Q] Can I back up an Optimus G Pro stock rom with TWRP and...

And use that to restore what is currently an F240 to Stock ATT? Clearly I have to root the stock one and install twrp, then back up the rom. If I get TWRP on the other device can I restore the stock rooted rom onto the F240? Has anyone done this?

How to restore ZVG back to stock ?

Im on ZVG and i messed up my recovery someway or another and i need to revert back to stock or factory reset it but i have no idea how to do this, this is my first LG phone and i don't want to completely brick it. The phone works but the recovery doesn't and i want to install TWRP and flash a rom.

There is thread in the LG G2 General forum that has all the info you need. You need to get a tot file and flash it using LG recovery tool. It works. I have done it successfully a few times
