TWRP and Magisk fixes the NFC Issue!

Congratulations! Here's how to get your NFC / Google Pay working again...

Download this recovery image file:

twrp-3.2.1-0-albus.img

Follow these instructions to load TWRP with the above image file

https://www.techrrival.com/flash-recovery-adb-fastboot/

Get Magisk-V19.3.zip ( Don't get V20, it loops the bootloader ) from here.

https://github.com/topjohnwu/Magisk/releases

You can upgrade to Magisk-V20 later after it's all working.

This gentleman describes the total process. Here's his complete process and download links for everything you need:

https://www.cyberkey.in/how-to-root-moto-z2-play-100-working/

I have updated his process with my notes on certain steps:

Step 37 needs to be changed to this: ( Do this in advance )

With the phone connected to the PC, just copy paste Magisk-v19.3.zip to the Moto Z2 Play before launching TWRP. I have a 128 GB SanDisk micro sd. I copied Magisk-v19.3.zip there first, because TWRP lets you choose the Source Location of any ZIP/Flash file that you want to install.

Skip steps 40 thru 42

Do steps 43 thru 45

Skip step 46

Do step 47

Steps 48, 49 and 50 are Your Dream Come True!

Congratulations! Your Moto Z2 Play is now rooted via Magisk and the NFC / Google Pay will work again! :)
[Moto Z2 Play  Guides, News, & Discussion] euskalzabe:
OK, thanks! I might try that, however, it would be infinitely easier if I can simply re-lock the phone, which takes a couple minutes. Considering I'm using Moto's official Pie build, is re-locking possible?

Relock Boot Loader Question?

This gentlemen has some interesting information on relocking the bootloader of your Moto Z2 Play.

https://www.theandroidsoul.com/relock-bootloader-fastboot-android/ :)

I have chosen to leave my bootloader unlocked because I am using the TWRP recovery program as my recovery tool. I can't go back without a total reload.
[Moto Z2 Play  Guides, News, & Discussion] euskalzabe:
Well, no luck. The whole process goes smoothly until trying to lock at the end, it says the boot.img has a bad key, and keeps requesting a valid file. So I guess I'll try the TWRP/Magisk route after a few of my trips are done - can't not have a phone during those! Then again, if NFC payments are the only thing that isn't working, it's not such a great loss in the meantime - I'd much rather have Android 9 than paying without an actual card :)
[Moto Z2 Play  Guides, News, & Discussion] euskalzabe:
I've tried to do this several times, but every time I try to flash TWRP it tells me that the image is corrupt:

(bootloader) is-logical:recovery: not found

Sending 'recovery' (15564 KB) OKAY [ 0.536s]

Writing 'recovery' (bootloader) Image not signed or corrupt

OKAY [ 0.104s]

Finished. Total time: 0.681s

So, I don't really know what to do at this point...

UPDATE: Actually never mind, even though it said that, I was able to boot to TWRP! I'll keep going with the steps.
[Moto Z2 Play  Guides, News, & Discussion] dpomales:
TWRP loaded

That's a normal error message. Now just get into the boot loader and lauch Recovery Mode. :)

Hi all, i have 09 device with stock oreo and unlock bootloader. Is it the problem with this Rom is just the google play? Or its mean the NFC cannot start (we need NFC working for android beam)

And can we just install this rom withoud deleting userdata?

Thank you

Update:

I just installed the rom and skipping erase userdata and carrier. my phone is good to go. Everything is working good. NFC is working good..m

Have you guys come across any film/glass protectors for the back of the phone?

I can't find a skin anywhere and I'd love to not add bulk by adding a case.
[Sony Xperia 5 Accessories] Dioser:
Did you try ask Dbrand? They don't have Xperia 5 in the lineup, up to zx3, but I'm almost sure, they'll do you one if you ask. :)

And I guess even if they won't, you got nothing to loose by trying mailing them. :good:
[Sony Xperia 5 Accessories] thatguy222:
Unfortunately I don't think this phone has anywhere near the user base for dbrand to produce for it. They're a Canadian company and Sony doesn't offer any phones there currently, and they barely sell any phones in the US.
[Sony Xperia 5 Accessories] Dioser:
Thought it was worth a try. ?

Maybe ES then? EasySkinz? You cant know, unless you ask?

Dbrand is to me known, for making skins to whatever, if they get the job. I could be misunderstanding though.

Otherwise. You could just buy some quality m3, and do one your self? With a scalpel and heat? You'll have some try and error in a single sheet. Can't see it should be that hard really. (Just a brainstorm idea, I wouldn't be scared to try, and in what ever color or pattern you wish?) Win win imo. You just need to do the measurements and cutting your self. See it as a fun challenge! And make some custom sh!t! I'd love to try actually, but I'm using a case, and I don't have any m3 laying around. And nothing to use the rest of a sheet for so seems brainless for me to go out buy. When never gonna be visible. But I'd encourage you to try, why not?

:good:

Lastly. If not in mood to try your self. Go down to a car wrapper, with a box of beer 30min before closing. They'll wrapp this no time. I suppose.

:laugh: :victory:

That's a wrap. Lol

Guess I got nothing but bad ideas. Sorry. :confused: :laugh:
[Sony Xperia 5 Accessories] Dioser:
BTW I actually successful broke my first h9 tempered glass. Real glass. It was cheap but fitted Nicely. But it shattered, phone is intact. :good:

BTW, Dbrand got back to me and confirmed there is no plan to add this to their portfolio due to low demand. Very reasonable.

Oh I see mate. Was worth a shot. Then do one ya self, is the option I guess. Or some pro wrapper if not up for the task.

Sony released remote play for all Android phones this week with compatibility from Android 5.0 onward but it's recommend to have Android 10 to use a DS4 due to better compatibility drivers. Is there any chance you could rip the drivers from the OnePlus 7 or 7 pro on OOS 10 put them in a zip and flash them through TWRP or magisk?
[OnePlus 6T  Questions & Answers] Graffiti Exploit:
I think you just need to wait since the official update is coming this month of October.
[OnePlus 6T  Questions & Answers] Joe199799:
Not to argue specifics but the beta comes out this month and the full release is next month. But I understand your point. I still want to know if it's possible to do it though.
[OnePlus 6T  Questions & Answers] Striatum_bdr:
Drivers are in the kernel in Linux based systems. You can't just 'rip' the drivers. You have to find a kernel Dev willing to work this with a soon deprecated Android version... with yet unpublished oos kernel sources, only AOSP ones. Not easy

That's why it will be more easy to wait beta / official OOS. Or perhaps be ready to try one of the Android 10 ROMs floating around there
[OnePlus 6T  Questions & Answers] Joe199799:
Understandable thanks for the answer, I thought it was more like the adreno drivers that you could update through TWRP or magisk I forget which one I just remember doing it on my V20.

[One (M8) Android Development] TarekElsakka:
I was able to flash this using the latest TWRP but my M8 keeps rebooting to the fastboot/hboot screen. How do I boot into the ROM itself? My bootloader is unlocked but it may be old because I haven't used this device in ages.

Thanks!
[One (M8) Android Development] The_Walking_Playground:
Hi,

Did you flash Magisk? If so, you need to make sure you use the latest Canary version (linked in the OP). I also recommend using [MENTION=1162986]Captain_Throwback[/MENTION]'s TWRP from here: https://github.com/CaptainThrowback/android_device_htc_m8/releases rather than the one in the OP as it appears to be newer.

And for GApps you should be able to use the Beta OpenGApps for arm, but make sure you boot into the ROM once first before rebooting to recovery to flash them.

TWP

EDIT: It's also possible you're not on Marshmallow firmware, so make sure you update to that first before trying to flash the ROM.
[One (M8) Android Development] TarekElsakka:
[MENTION=8756890]The_Walking_Playground[/MENTION] Thank you so much for your reply. I have a strong feeling I am not on the latest firmware, so could you please instruct me on how to update to it?

Dear all,

I was looking to upgrade LG G4 - H818P.

The below steps are updating properly the mobile but not all features are working but the phone remains usable as a mini tablet.

I did not create anything. I just followed other threads. Congratulations to them for their work. I am not a developper neither a rom cook.

I decline all responsabilities if you brick your phone. If this is the case, please use LG Bridge. Not tested but a thread covers the topic.

All credits to other threads owners. Thanks

Not working

Dual sim support

Micro SD card

surely other features.. under testing

Working

all the rest...

Instructions

STEP 1 = boot loader unlock and TWRP install

I followed this thread but I did only STEPS 1, 2 and 4

https://xdaforums.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003

STEP 2 = Install the last version of TWRP

Download and reinstall the last version of TWRP.

https://twrp.me/

STEP 3 = Dowload the Rom Lineage 16 and modify it

Download the lineageos 16 from below thread.

https://xdaforums.com/g4/development/rom-lineageos-16-x-17-x-lg-g4-android-9-t3964665

I know this is for version H815 but let's continue.

_ Unzip the rom

_ go to the folder : META-INF\com\google\android

_ rename updater-script into updater-script.txt

_ edit the file and replace the first p1 with h818:

getprop("ro.product.device") == "h818" || getprop("ro.build.product") == "p1" ||

_ rename updater-script.txt into updater-script

_ edit the lineageos 16 zip file and replace the updater-script with the one in the folder

_ save the zip file

_ send the ROM to the phone - not SD CARD.

STEP 4 = Install the rom

_ please use TWRP to install the rom

_ Wipe before and after the phone

Enjoy and all credits to the people that cook the rom.

If any question, most of resources can be found on the XDA developper forum.

Enjoy.

Next step... looking to learn cooking a rom.

Thanks for reading.

For Admin; if any issue with the post, please let me know or feel free to amend.

LG do not allow unlocking for anything other then the h815 international (which you likely have or better said a Frankenstein with the board of a h818 but a refurbished bootloader stack of a h815) and the h811 (fastboot needed only). So I fear real h818 users will not be able to use your guide.
[G4 General] lesteph4920:
Hello,

In fact, that's what lg said on his website.

I tried the process of unlocking with h818 instead of h815.

So please try it and in my case it worked. I hope same for you.
