Cannot flash custom roms

Hi Guys. This problem has me beat and i have been searching around for an answer but cant seem to figure it out
Running the LG E975 - 4.1.2 stock rom on build e97510b. This phone was from ebay and as far as i can tell its from taiwan (has taipei set as default timezone)
I rooted my phone successfully (checked using root checker)
Used freegee to unlock the bootloader and install CWRecovery 6.0.3.0
I Have tried an AT&T Rom, International rom and a rom from the "android development" section also
None of these roms will flash (always says fail)
The error is;
Assert failed: getprop("ro.product.device") == "e975" || getprop(ro.bui
E:Error in /sdcard/Roms/"rom name".zip
Status 7
I have read it could be due to the first line in the updater-script file. i have tried deleting it, saving it however notepad wont let me just save over it. i need to save it as a new file, and replace it in the zip but when i try to replace the file in the zip it says it cant do it due to invalid or corrupted file (surely not every rom ive downloaded is actually corrupted)
Any help with this would be much appreciated. Thankyou in advance

Have you considered they are called e970 roms for a reason?
Use kdz updater to flash stock e975 rom,then root and unlock. After,flash e975 roms. Id you want e970 roms,buy an e970.

Really this is something i can't understand.
Means, you have a e975 so why the heck you flash roms from at&t? And that for the first time you flash a rom on this phone. Why not choose a rom for e975 to be sure that nothing happen. Or maybe you like it more dangerous)))
You should better inform yourself (reading helps) before start flashing roms.
A rule of thumb: flash only that, what is made for your phone(modell)

The at&t rom was an accident, and once i realised it i downloaded a proper e975 rom. The international one and the regular one are boh e975 and they do not work. I think you missed the point im trying to make here, no rom including 2 types of e975 rom will flash due to the error i am receiving

Can you tell what roms aren't working?
Btw. the error you get is only when you flash a rom from a different modell, it's the updater script.

Sure. I have tried Pacman, CM10.1 Nightly and beanstalk
all give me the same error
I am bout to try to flash the "geehrc_unsigned_stock_rom_E975_INTL.zip" rom which is version 10E, my current is version 10B. if this works i will try to flash from that rom to a custom.

Ok i was just able to flash the "geehrc_unsigned_stock_rom_E975_INTL.zip" with no problems in CWRecovery so i did a backup and tried to flash the CM10.1 Nightly and it failed again. im not sure whats wrong

It was the same error as in my original post. I worked out what was wrong just now. Even though i selected CWM recovery in freegee it for some reason still installed TWRP. I did a nandroid restore to the original rom, used freegee again and selected CWM recovery. this time it installed it correctly and roms are flashing properly now. thanks for the help anyway guys

Problem solved and thread closed...

E988 users, have you managed to flash a custom ROM?

I've observed that quite a few people with the model number E988 have been having trouble in the modding(?) process. Mostly from due to unlocking and flashing a custom recovery via FreeGee (no offense intended to the maker of FreeGee)
So out of curiosity, before I have to unecessarily attempt the dreadful Recovery process again, have any of you guys managed to flash a custom ROM on your E988? If so, how?
(sorry mods if this is in the wrong forum).

I have flashed and used almost all the roms available in the original dev section.......no problems what so ever...... only one rom was problematic....... that is the PA port........ though not mandatory, keep the modem zip handy.......

Install cwm and disable lg security via freegee...and install rom without flashing modem is ok...working..only change apn..
But you can't back to stock rom without flashing kdz..
Once you reboot you can install rom via cwm but can not enter stock rom...

Looks like freegee does not work anymore. E986 or E988. Alternatives? Thanks.

FreeGee works fine on E988. I own one (Indian variant) and I can vouch for it. All you have to do is select "No" on the disable LG security option. CWM will get installed just fine. And since the FreeGee recovery is lokified, you are good to go for any rom including 4.3 ones. Like I said in my previous reply, I have used almost all the roms available in the Original DEV section. Only the PA port causes issues with the signal reception. Rest all work fine. If you are facing problems, be specific and I will try to help.....

What I did was root my device (you'll need root for FreeGee to work), install FreeGee, let FreeGee back up my nonsense, Disable LGE security, install TWRP. From there you'll have a custom recovery and you'll be able to flash CM or whatever other ROM you'd like.

Better is very subjective. I'm a fan (and builder) of Carbon for the G Pro because it has a little more customization than CM. We have a few good options, though, so pick one and flash away. If you don't like it you can always flash a different one.

[Q] CM11 official & AT&T LG E980

FIXED: I needed to unlock the boot loader. Let that be a lesson to you.
I have the AT&T LG E980 and want to upgrade to the CM11 firmware. My device is rooted and has recovery installed. When I try to install CM11, I get status error 7 and the firmware reports that it's compatible only with E980 (et al) devices.
Do I need to do the workaround with notepad and edit the specified text file? Is there a check I can do to make sure I'm doing this right?
thanks,
eah

Secure boot error means that your kernel didnt pass system checks?
What rom are you trying to flash and what firmware version are you currently on?

I'm not sure what my firmware is but I'm running google 5.0 lollipop and Im trying to install cm 12.1

Writing again because im still having the same problem. I tried rooting again and installing a new kernel the 777 kernel for d855 and im still getting the secure boot error, anyone else ever have this problem i feel like ive tried everything

If you rooted from 5.0(Not restored to Kitkat then root then flash to Lollipop), You need to install Kitkat Bootloader and aboot as they fixed the issue in Lollipops bootloader.

try Auto Rec from playstore to solve your problem of "ecure boot error" on rooted Lg G3 D855 international

You need the Kitkat Bootloader, you need to flash Kitkat via LG Flashtool then enjoy custom roms

OK Guys so i figured out my problem, it seems to be that if you install multirom it completely messes up your recovery. All i did was install AutoRec again and it was good to go! Hopefully this helps anyone else with similar problems
