[Unofficial][Joan] TWRP 3.2.1 [Oreo firmware]

[SGCMarkus]

Introduction

This is a TWRP 3.2.1 build based on an oreo kernel which seems to be required for the oreo firmware of the H930. Currently Im using the kernel from my stock based ROM. In future updates (when i have the time for it, and if its needed) might make it smaller, by removing things like network, wifi and so on drivers. But for now, it works.
The name of the device (which it also checks for if you flash a ROM that has an assert so you wont flash it on the wrong device) is "joan", as thats the official codename of all V30s (inclduing V30S). I decided to that because I want to unite the H930 and US998 development, as the US998 seems to have no problems with H930 roms/kernels.

Bugs/Features

Its basically the same as this TWRP, just newer TWRP version (3.2.1 instead of 3.1.1), newer kernel, and renamed device.
So please for things that dont work go over there. I maybe plan to fix a few things here and there, but its really low priority for now.

FAQ

1. • Why is there now a third TWRP Thread?
   • The old recoverys dont boot on the new Oreo firmware. This is an updated version that boots on it.
2. • Will this work with the nougat firmware too?
   • I havent tested it, but it should work, as it uses the same kernel as my korean oreo port.
3. • Whats so special about the Treblelized version?
   • It can mount/backup/wipe vendor, also flash an image to /vendor. Thats basically it.
4. • Can I flash a treblelized ROM with the normal TWRP?
   • Yes, you can. You just need the treblelized TWRP if you want to (nativly) mount vendor, or if you want to backup/wipe vendor.
5. • Can't everyone just use the treblelized version?
   • It's specially intended for people who have repartitioned! You can try, but idk what happens on phones that arent repartitioned, and you use this. Beware of unexpected behaviour!

If it's not problem for you, can you made a flashable zip for TWRP?

You can flash an image through TWRP too if you want to update your old one.
In the install menu, switch from "Install zip" to "Install image" (bottom right it was i think)

 

[Dizzyrul3z]

Damn I did not know that we lern all the time waiting for your rom to flash in twrp and we all be happy

 

[kherio]

maybe a stupid question, but must I flash before the no-verity-opt-encrypt-6.0.zip ?

Depends on the rom youre using. the Custom Stock based ones have disabled verity/force encryption already built in what i know. If youre using pure stock, you need to do that once (after you change the boot image).
E.g.
Flash stock rom via kdz -> flash recovery -> format data (if it should be encrypted and twrp cant read it) -> flash no verity-opt encrypt -> flash lrcd (or whatever its called, service that checks if you have root or not) -> flash magisk or so -> setup rom
Thats how i did it, but that doesnt really have todo anything with the recovery itself

Flashed fine from within TWRP. Now waiting for the new Oreo, I'm running the Korea ROM on my unlocked US998.

Sorry but I must be doing something wrong or there is a bug as when I install TWRP and I try to access it no matter what I do it always erases everything.
Please let me know if I am doing something wrong.

Thanks

What do you mean by "it erases everything"?
What are the steps you use when you install it?

try after you flash it with "fastboot flash recovery xxxxxxxxxxx.img"
to use this "fastboot boot xxxxxxxxxxx.img"

the way taht i managed to acces it is like this
- flash twrp
- power off phone (DO NOT power it on to enter in its rom)
- press power and volume down
- wait for the first "LG V30 ThinQ" logo to appear
- while i HOLD volume down i let the power button go then press it again
- the black text on white background will appear before the screen which says that you have your bootloader unlocked
- select yes using volume buttons
- press power
- then select yes again
- press power and that's it, just wait and it will enter in recovery

can i flash this in korean model v300s ?

 

[ChazzMatt]

can i flash this in korean model v300s [emoji848]

No, unless you have a way to unlock the bootloader on the v300s -- and have fastboot flash commands.

Thanks very much for the reply. I have tried this exact procedure but after the second yes it erases everything on my phone, and I tried this more than once.
What I have not tied is the "fastboot boot xxxxxxxxxxx.img" I will try this too and see what happens. I will let you know. Thanks again.

I can confirm that "fastboot boot xxxxxxxxxxx.img" is working on my V30 but NOT the key combination

the key combination can be rather tricky, and you need a pretty good timing for it too, i rarely manage it on the first try ?

I see, this is not a problem I would rather use the fastboot command which is more safe that the key combo.

Thanks very match for your help

 

[iRS_]

the key combo sometimes tricked me because the twrp was not properly installed and i ended up erasing everything... i always use fastboot command or TWRP official app to reboot in recovery. those are the safest procedures

 

[mauley]

Not sure how so many people are having issues with the key combination, it is very easy to do. I have updated to Oreo and have unlocked, installed twrp and rooted it successfully first try.

1. Hold both volume down and power until you see the first logo
2. Let go of power while still holding volume down
3. Press and hold down power again, along with volume down
4. You will be on a white screen
5. Choose yes and yes, you have to do this erase procedure twice
6. After the second erase you should now see the twrp splash screen

That is exactly how i did it and it was successful on the first try. I have tried same procedure again 4 times since and have don 2 of my friends phones, all worked perfectly first time
