[OFFICIAL][RECOVERY][QUALCOMM] TWRP 3.1.1 For LG G4c

[pvineeth97]

Hi guys!

I built TWRP [Ver: 3.1.1] from scratch for LG G4c.

Update: TWRP is official now!

* do some research if you have any concerns about features included in this Recovery

* you point the finger at me for messing up your device, I will laugh at you.

Supported Models:

LG G4c

First, UNLOCK the bootloader!

Steps:

(1) Download the Official TWRP App.
(2) Open Official TWRP App > Select TWRP Flash > Select A Device > Search for G4c (c90).
(3) Select G4c (c90). Then select "twrp-3.1.1-0-c90.img".
(4) It opens a broswer and select download "twrp-3.1.1-0-c90.img".
(5) Open Official TWRP app again, select "Select a file to flash.." and select the file you just downloaded and then select "Flash To Recovery". Confirm flash.
(6) Then reboot to recovery.

You are in TWRP!

NOTE: To boot into recovery with hardware buttons use this method. Power off the device > press and hold Power + Volume Down buttons simultaneously > keep pressing them until the LG logo shows up > when the LG logo shows up, let go of the buttons for 1 second and then press them again. A factory reset menu will show up. Select "Yes" two times to "wipe" your device. Don't worry, this will actually NOT wipe your device. It will boot into recovery normally. This is because LG phones are a bit different and they instruct the recovery (TWRP in this case) to automatically perform a factory reset of the phone by triggering the /misc wipe flag. I mapped /misc partition to a different partition (/pad) so TWRP doesn't perform a factory reset.

BUGS:
None!

Thanks to my friends on XDA for helping me in building device tree and building TWRP from scratch!

Thanks for your efforts in porting TWRP to the H525n. Hope this will motivate skilled people to unlock its bootloader.

Side questions:

- Did you test it?
- How is it affected by the locked bootloader
- What can we do exactly with TWRP, flashing easily stock roms (that would be terrible )?

Thanks again!!

I will be posting the bootloader unlock method in few days. After that you can flash TWRP. Yes you can easily flash stock roms through TWRP.

You are the man!!!

Hey, by the way, why didn't you post it into the LG g4 forum? You would have had more visibility from H525n owners no?

Hello, do you mean this is the patched aboot that unlocks the phone!?

Thanks man!!

I unfortunately won't do it now as it is for my wife's phone and someone got long term sick in her family. So it's not time now to mess up with her phone.

Just for my information. Do you know to which stock rom version this aboot is linked?

Thanks again man!

It doesn't matter which stock rom the aboot is linked to.

Ok thanks. So if I understood and read well, this aboot is the one from the H440n (LG Spirit) and not the original from H525n but they are supposed to work anyway, correct ?

Yes.

 

[Anghirrim]

Yes.

Should we follow the instructions from this post?

https://forum.xda-developers.com/lg-k10/how-to/bootloader-unlocked-guys-bootloader-t3558810

So I guess we should use the following post partition layout to identify what needs to be flashed (unless you already know it when you built TWRP)?
