[Q] Can LG G4 flash zip without a custom recovery? - G4 Q&A, Help & Troubleshooting

As the title say, i've come across an app called Flash Gordon which can flash zip without a custom recovery like twrp/cwm. It seems like it is made for devices with a locked bootloader. I dont know if its gonna work on our G4s. Have someone ever tried it? Especially those people that have a nandroid backup so if anything happen they can revert without an issue. I have a locked bootloader so i dared not to try.

i'd like to know that as well...proud possessor of LG G4 H818P and trying to install the Xtrememusic mod

Yes u can using flashfire app

Switch recoveries

Is there a need to switch recoveries when switching back and forth between kitkat to JB ?
Do you mean from cwm and twrp and contrariwise? No, you don't need to.

No for JB you don't need but for KK you must have cwm 6.0.4.4 and about twrp i m not sure.

So basically need to switch to older recoveries every time switching from kitkat to JB ?

Ic, so newer recoveries for this phone are backward compatible

Yes.
What is the difference between loki-fied and not loki-fied recovery ? .. when do I need which ? Shellnuts freegee and cubes cwm and twrp threads don't say if their recoveries are lokified or not. Phlis touch cwm thread makes a mention of it, but was very confusing, "lokified during flash" , what's that supposed to mean ? He also speak of lokified if bootloader is locked ? So if bootloader is unlocked through freegee you don't need a lokified recovery ? ... I'm super confused ..
I have flashed every KK ROM for the e980 with CWM 6.0.3.7 without fail, fwiw
e980 - I'd tell you which ROM, but I'd have to update my signature thrice daily

Thats good to know. Did you get the recovery through freegee ? Do you ever switch back to JB ? Switching back and forth without issues too ?

Yes, I got this recovery from Freegee. First and only recovery I installed. Have never updated it, because if it ain't broke...
When KK first came to the OGP, I switched back and forth between that and Vanir 4.3 and BS Harmony 4.3 with no problems, back or forth. YMMV, but for me there has never been a problem. One thing to note is that I haven't flashed any of the stock based roms. I am a custom ROM guy through and through.

The OGP has a locked bootloader. We use Loki as a way to bypass this so we have the full functionality of an unlocked bootloader. The recoveries included in freegee have the loki bypass just as every recovery here on XDA, for our device, has it (I think).
Stock-based ROMs don't require loki as they can run on the stock kernel included with the phone while loki is needed for AOSP-based ROMs due to the change of kernel. Without an unlocked bootloader (or Loki in our case) we'd be stuck on stock-based ROMs which is exactly what happened to the Atrix HD.

Thanks man. Sounds like HTC s-on/off
I guess the next obvious question is why wouldn't people just unlock through freegee ? Is it not reliable ?
I rooted mine with 10p and 10k, used a flashable 10k and used lg flash tools. As of right now I still have this error message coming up in freegee telling me "com. lg.hidden menu has stopped working. I thought maybe there was something wrong, that's why I did all these flashes and recoveries. But I still get this error in freegee. I have also NEVER to date seen the "unlock" or "security off" option in freegee.
The last recovery I did was because I flashed a security app, Cerberus, to my phone and it caused it to get stuck on the LG logo. When I flashed Cerberus I got some error message at the end about there being a Loki error. It was a long name and I don't remember it off hand. You guys have to forgive my ignorance as this phone is new to me and I'm just learning all this stuff for it. Am I doing something wrong here? Is there a way to unlock the bootloader now without using freegee? I don't plan to flash a custom rom on here so is freegee and an unlocked bootloader even needed?
Help me out here guys. A really good in-depth sticky on all this stuff would be great but there isn't one, that I found anyway.
That's interesting. I unlocked my optimus g with freegee. I thought one couldnt even have a custom recovery with bootloader locked .. Maybe this is where the Loki thing comes in play
Don't blame yourself man, it is very confusing here with all variants of the phone in one forum. Also I don't think you'll need freegee at all since you aren't planning on using a custom rom.
Freegee is what I used as well. Yes, it's pretty much like S-Off for HTC which is why you see the Secure Boot Error message on boot. :3
For the OGP, instead of freegee unlocking the bootloader it applies Loki. On my old LGOG (E970) freegee actually unlocks the bootloader. But having a locked bootloader has saved me quite a bit of trouble. Just now got my 4th replacement phone (Middle of the screen was waaaaay too bright compared to the rest) for free by using LGFlashTool and putting it back to stock before sending it in. Otherwise I would've ended up owing AT&T around $1,200 lol.

[Q] Root + Recovery question

Hello,
I always had a HTC, so I'm kind of a new with rooting and unlocking an LG.
I have a LG D855 international and I have been reading a lot in this forum and I think that I've figured it out. But I just wont to be sure.
So if I'm right than I can root my phone by running purpledrake. When I've done that I have to install SU.
But if I understand it correcly the only way to get twrp is with" Bump'ed TWRP" so it's only possible to have TWRP if I use a custom rom?
So it's not possible to have orig Rom an TWRP? Right?
But If I just root my phone with purpledrake, so without installing TWRP and without custom Rom, I would still be able to use EXPOSED? RIght?

Yes Purple Drake is currently the most reliable root method, once you have root you need to install the SuperSU app of your choice.
Don't confuse yourself with Bump! Just accept that this is the only recovery that works with the G3 and install it then use it like normal. You will only be able to flash custom kernels (and roms with custom kernels) after they have been bumped, this is something the developer will do for you not anything for you to be concerned with, and fairly soon (when this method is released) all custom roms and kernels you find on xda will be pre-bumped - so basically you can treat the recovery like you always have done.
Xposed is nothing to do with recovery and everything to do with having root access.
Does this recovery back up my stock rom safely? I'm hesitant to use it because I've never heard of bump.

Nope, afaik, once on bumped twrp, u can't restore stock recovery. For that you will again have to flash the stock KDZ.
OK so it's only for bumped roms. Thank you

The user above you is wrong and didnt read your question properly.
You CAN back up your stock ROM, just install bump, head to recovery and do a backup - you will never get stock recovery back though, unless you flash a KDZ with Flashtool.
But yes you can use TWRP to back up your currenty stock ROM.
Okay I get it the only way to restore the rom that I backed up is to add bump to it! ok I got it but in order to get back my stock phone I'm going to have to use the LG flash tool right

First you should do some reading just to brush up on flashing. TWRP is a recovery, not a kernel. I think there is a how to guide in forumland somewhere. You have to root first using purpledrake, towelroot, uproot, etc. Then you need to get the latest twrp .img for your appropriate model phone. Flashify that. Pick ROM of your choice and voila. Backup your stock just to have it. But seriously I would definitely read up before you break your phone.

How can I unlock bootloader for LG Optimus G Pro e980

I have already tried freegee many times, but it never works. Is there any working method for my phone model? Pls help.
Or if anyone has the latest twrp for my phone in a flashable zip format, that would be great.
Freegee dies not work on KitKat stock rom. Are you on kitkat? Look up on xda soecifically for rooting kitkat rom. To unlock bootloader you need to install og pro recovery apk. Again Google for that. Once tgat is done you can flash twrp via flashify. Let me know if you need more info. My info is based on my experiments with my lg e988. Btw what rom do you want to try? For me all AOSP lollipop roms did not work well.

I've already installed CWM recovery and now running CM12.1 , But I still can't figure out how to unlock bootloader, when I try to use CM's advanced boot to boot into BL, all it does is normally boot up my phone.
Well i have never tried to boot into the bootloader. So i dont know what happens when i do that. I will try it once i get home and post again.

E980 doesn't have a bootloader unlock, just bypass with Loki. If you need fully unlocked bootloader, well, bother LG.
