My set up.

Variant - L-29

Model - C432

Firmware - 131

I have rebranded btw, I was L-09, 782, 110 previously.

I think it may be something to do with either ramdisk or boot IMG, both of which have been changed at some point whilst tinkering with ROMs and updating firmware.

I think a format and an eRecovery back to total stock (back up first)

Then install twrp, don't root and then install a treble ROM which has been reported to be working..

[MENTION=1096076]reppi[/MENTION] didn't have issues on Havoc or RR. omnirom had yet to be updated so I think the first two would be good to test.

Make sure it's the A-only ROM too.

Magisk installation and G-Apps can be installed with the treble ROM.

So in order.

An actual format from twrp

eRecovery back to stock.

Install unofficial TWRP

Remove security

Factory reset, cache and dalvic from TWRP

Install Treble ROM, G-Apps and Magisk (16.6 works well)

Test for reboots.

Mine failed after 7 minutes and 47 seconds.

Having a log cat for this time would be gold for anyone who can diagnose from it.

Least that's what I think is the best shot we have to install it.

Just one question.

During a format (not a wipe)

What would be best to format and what is safe to? So eRecovery works thereafter?
[Huawei P20 Pro Questions & Answers] psycho.b94:
Hmmm. If you have a log cat then try posting the issue on Phhusson's treble thread. He's the main tinkerer for treble I believe the rest of the roms are based on his build too. Hopefully he'll send a reply
[Huawei P20 Pro Questions & Answers] dlads:
Yep I've read the same, I don't have treble installed at the moment, i think if it worked for [MENTION=1096076]reppi[/MENTION] then it'll work for anyone.

There is also the case of doing the same and deleting system/bin/ucrypt which was phhussons advice to reppi
[Huawei P20 Pro Questions & Answers] reppi:
It's so weird that it works for some and for some it doesn't.

I'd love to run a custom ROM but as long as there's no 100% working camera port and dual speaker mod I'll stick with EMUI.
[Huawei P20 Pro Questions & Answers] dlads:
The camera is working mate. Works on lineage anyway, plus I found a work around for the gallery too..

New thread in the guides and discussion section.

Stereo speaker no but what i do is just turn on mono and it works fine. No loss of audio.

---------- Post added at 09:54 PM ---------- Previous post was at 09:53 PM ----------

Also you said that the two ROMs RR and Havoc didn't reboot?

Did you test it by leaving them for more than 10 minutes?

Have you ever flash no check recovery before?

Did you revert to stock prior to flashing treble?

Ie: a format not a wipe.

Just trying to work out why? Also were you rooted with magisk at the time. If so what version?

Cheers
[Huawei P20 Pro Questions & Answers] reppi:
Just asking because since now everybody including me reported that pictures don't get saved when AI detects a scene, even portrait mode.

Yes I had tested them for more than 30 mins each after people reported that those random reboot issues had been solved. And I didn't have any reboots as well. Reverted back to stock because of camera actually.

I think to remember that I flashed no check recovery long time ago but I cant tell 100%.

Nope I even flashed one treble ROM after another without going back to stock in between.

Yes I was rooted with magisk. I think it was v16.4 that time.
[Huawei P20 Pro Questions & Answers] dlads:
When you take a pic. Go through my workaround. And it's fine..

I'll grab the link for you mate.

Edit: here you go

This is the gallery I've been using.

Landscape works fine as I say in the guide but in portrait if you take a pic then jump to gallery it won't work, but jumping to recents will work.

[Huawei P20 Pro Questions & Answers] Bryski:
Anyone manage to get a treble working?

If so, which one and what steps did you take?
[Huawei P20 Pro Questions & Answers] dlads:
Working is easy, but if you've rebranded then it'll reboot every ten mins, if you haven't, then you should be fine.

Wipe data, cache and dalvic.

Install Treble to system, it's an IMG usually.

Flash mind the G-Apps and Magisk then let it boot.

That's it.

Omni ROM works. RR unofficial and havoc.

But if like me you committed to rebranding then it'll probably reboot every 6-9 minutes.

Such a damn shame, they all run so well.

Obviously you need to disable security prior to booting to twrp.

Let us me how you get on

This is my thread for the reboot bug, no one has responded, the support just isn't there.

I cant even get any to boot yet, tried Havoc, PixelExperienceP and Benzo, none will boot :/

I assume I am downloading A and not A/B?
[Huawei P20 Pro Questions & Answers] reppi:
Yes A only. Haven't had any issues.
[Huawei P20 Pro Questions & Answers] mrabcx:
Maybe you should try to unbrand, go back to your original type and then flash Treble ?

Lol only one other guy is up did that, ended up with a brick.

---------- Post added at 02:17 AM ---------- Previous post was at 02:15 AM ----------

Maybe Huawei wants you to lose.

I've even read there's an update to eliminate magisk?

FFS why did they bother with treble if this is their attitude?

So bad!
[Huawei P20 Pro Questions & Answers] Bryski:
Reppi any chance you can give me a walk through of the exact process you used please?

[Huawei P20 Pro Questions & Answers] psycho.b94:
Still trying to keep my hopes up. At the same time considering getting Oneplus 6T when it's out... Did you test any other treble related roms yet? I'm planning to soon, still very annoyed about not getting EMUI 9 beta though.
[Huawei P20 Pro Questions & Answers] dlads:
Tried Omni, havoc and RR.

I'm going to rebrand back to L-09 and then flash some
[Huawei P20 Pro Questions & Answers] dlads:
I have got my eye on the 6T. Only problem is it'll have the 845, pretty sure it's already made so 845 it is.

Out of that and the pixel id have to say pixel.

The XL version, that will be a monster with a truly epic camera.
[Huawei P20 Pro Questions & Answers] psycho.b94:
Well yeah but pixel phones don't get too much development over Oneplus phones, mostly just treble. From my experience I prefer Oxygen OS over stock android so I'm leaning towards oneplus. I'll only consider it if it has a battery size of 3700 Mah or more. Too used to the great battery on the p20 pro. As for the camera, I have people with me with Galaxy S9, Note 9 and iPhone X, so I don't really need to be the camera guy. Don't get me wrong, I love cameras and I'm a big fan of night mode on the p20 pro, but at this point I'm prioritizing my daily satisfaction over rare instances of photography.

Also I'm not a fan of the pixel 3 notch as seen in the rumors, It's too big.
[Huawei P20 Pro Questions & Answers] reppi:
And an epic notch :D that's a real killer IMO. What's wrong with the snapdragon 845?
[Huawei P20 Pro Questions & Answers] dlads:
No nothing mate, but I think by the time that the 1+7 comes out, you'll be left wanting more than you would from if a whole year passes by, bare in mind the update cycle the pixels receive ahead of other devices is a defining factor too.

There's quite a difference between them in terms of quality and received updates, not to mention the camera, no OIS being a big one for me.

I'm not bashing 1+ I've only had the one device and it's a beast, my friend now has my old 1+5 I swapped it for a smart watch from him (montblanc summit)

But in comparison I would have picked the pixel 2 XL compared to it if given the choice as we will have between the 6T and the Pixel 3 XL.

Perhaps the One 7 would be the better option but that's not til later on in the year and hardly a fair comparison.

That's my point, nothing wrong with any of the devices, but in comparison the pixel would be the better choice overall, it is just is.

---------- Post added at 12:06 AM ---------- Previous post was at 12:00 AM ----------

Do you know that the pixel 3 XL has a notch? Are you sure? I've not seen the final model so I couldn't say.

Personally I don't care about notches, doesn't bother me , I actually like my time on one side and the signal on the other. Ive actively made this change to my phones so having it done for me is a massive help :good:

Also development? Hmmm I think you're mistaken, 100% for camera development, the g-cam for the OnePlus 5 was not great, certainly didn't have the quality the pixel 2 had, not even close although it did get a great port, it just wasn't the same.

And in regards to ROMs? Just treble? Lol that's just not true.

All of the main ROMs are there AFAIK, not to mention that treble ROMs will work pretty much perfectly on the pixel devices anyway so I'd take that all the same.

Again, I loved my OnePlus 5 , in all fairness to both devices, there is no wrong choice. It's personal preference, but make no mistake the pixel is a top tier premium device and although I love the 1+, it's still regarded as mid to high, not top tier.

So again, for me, given the choice, knowing that something will be missing in comparison as well as updates etc?

Has to be the Pixel.
[Huawei P20 Pro Questions & Answers] psycho.b94:
Pixel is great, that's for sure. Sorry, I don't know much about the pixel 2, owned the pixel before and it had alot of rom issues. So you could be right but I don't wanna pay a premium for a device so soon after already paying quite a bit for this p20 pro. Even the fact that we are considering a phone cheaper than this as a replacement says a lot. Notches bother me because I've recently been into mobile gaming and it just looks like in the way to ruin a slightly more immersive experience.

Oneplus 6T will most likely have a very small notch so although it's not perfect I would still welcome that way more than an iPhone X style notch. Not trying to argue but I personally look at it like this:

Pixel phones are not worth the price, it's stock android with no extra features and a great camera. Sure it gets updates first and way more consistently, but every since Marshmallow or Lollipop, Android updates have been more incremental and less interesting, so as of now I would still be skeptical paying that much for that phone. With oneplus I'll be getting slower updates by a week or two or maybe a month but oneplus is no slouch either, you'll be getting consistent updates (if you join their open betas) for atleast 1 and a half year.

Pixel 3's price may just be short of $1000, in my opinion it's probably more worth getting a galaxy note 9 for that high a price as you get way more features to justify such a price point. Plus the treble implementation on Samsung devices is way better than our Huawei ones. My brother has a Note 9 and he's been running 8.1 treble almost perfectly and what little bugs he had just got resolved in the latest release. He can even use the S Pen to navigate through treble roms which is pretty neat. If you really prioritize official software updates and maybe camera (since there's only a marginal and nota magnificent difference there between the two phones there) sure pixel 3 would be a better choice, but I would still admit to note 9 being the all rounder in terms of features and a therefore more of rational buy (atleast for me).
[Huawei P20 Pro Questions & Answers] dlads:
I'd never buy a sammy mate, mine and their honeymoon is well and truly over.

As i said, there is no wrong choice here, both devices will be stellar and i feel you on the price, if it's too expensive then i may very well join you on the 6T :D
[Huawei P20 Pro Questions & Answers] bowlandspoon:
[MENTION=2880355]dladz[/MENTION], did you try to rebrand back to stock region? I have a feeling I'm in the same boat as you.

UK based P20 Pro, rebranded to C432. I haven't flashed any Treble ROMs yet but I'm assuming I'll get the reboots.
[Huawei P20 Pro Questions & Answers] dlads:
Get a back up (to PC)

Commit to flashing Omni ROM, you'll be surprised how easy it is..

Erecovery is there is you need to get back too so make sure you have a nice speedy WiFi connection, or just flash lineage from the dev section, I would be very interested to see if yours retains a boot past 9 minutes.

I personally havent rebranded back as of yet, I'm currently on 152 and I'm not sure if 152 is available for the 782 L-09 model..

Once it is and I get a minute I'll making a guide and going back.

Give the treble ROMs a shot mate..it's possible it's not the rebrand which did it, you're first I've heard from who's in a position to commit.
[Huawei P20 Pro Questions & Answers] bowlandspoon:
Was going to try Havoc 2.0 (Pie). Looking forward to native notch handling with Pie. You tried any Pie ROMs?
[Huawei P20 Pro Questions & Answers] psycho.b94:
As far as I know, you and I are the only ones having issues with treble, if other people aren't having any issues, we shouldn't either, there has to be some sort of issue that we aren't handling very well here... If I can get a perfect treble rom I wouldn't mind keeping this phone for quite a while longer. I don't want to trade this in, I love it, but my tinkering habits require some cool down, which is especially difficult when a company is trying to remove root access altogether. I'm worried if Magisk dev topjohnwu stops caring about Huawei devices in general. EMUI 9 has yet to be rooted and that just motivates me more to sell this phone off while it still has some good value..
[Huawei P20 Pro Questions & Answers] bowlandspoon:
I'm afraid that with Huawei announcing that they'll no longer issue unlock codes and the serious lack of 3rd party development we are doomed with this device. Don't get me wrong, EMUI is pretty decent but like you I love to tinker about with my device.

I recently dug my 1+3T out to take on holiday as I didn't want to lose my P20Pro and realised how much I enjoyed flashing ROMs etc. That device still has a really active community!

They way things are going I think I may trade my P20Pro in for a 1+6 (or 6T...).
[Huawei P20 Pro Questions & Answers] dlads:
Nah mate I'm not committing til everything is working. To a degree.

---------- Post added at 09:58 PM ---------- Previous post was at 09:56 PM ----------

Well unless you've rebranded there is a plethora of treble ROMs which is perfect as it offers a lot of choice.

Both myself and who you were quoting obviously have our bootloaders unlocked so we need to get this treble issue sorted.
[Huawei P20 Pro Questions & Answers] bowlandspoon:
I agree that there should be a lot of ROMs available via Treble. But there is still no one (or very few) working on this device. Even if we can got the reboot issue sorted there's always going to be issues like FP, dual speakers, native camera/gallery etc.

Don't get me wrong i'm not trying to be pessimistic, I think the device is great and I know some of these issues have/are sorted but I still worry about the future of it.

Having said that, when I have a bit of time in the next few days I'll have a go at flashing a GSI and see if I get the reboot issue.
[Huawei P20 Pro Questions & Answers] Dany21000:
With Huawei, now treble is a great feature without any possible usage.

The reason is simply because we can't put any other rom on their phones, with their ****ing bootloader locking strategy.

Envoyé de mon CLT-L29 en utilisant Tapatalk
[Huawei P20 Pro Questions & Answers] dlads:
No that isn't true mate, I know of three? And they work very well, as well as the lineage ROM here does at least.

RR unofficial

Havoc

Omni ROM.

The only problem is that I have rebranded.

Please search for project treble.. the section on XDA is for a large amount of devices, we need type A treble ROMs for ARM64 which the aforementioned ROMs work for. The only problem was if you rebranded then you got reboots which has been fixed for people who didn't rebrand.

Sure there will be the odd issue, the camera can be looked at, there are dual speaker mods all over the internet, the notch can be fixed with k-manager

The gallery, I have a thread about with a work around..

Hope you give it a shot though pal, we havent got any Devs looking into anything for us so we need to have a look..the audio I think should be fixable..the gallery has to be done per ROM though so that's a pain. But the port on the other hand (camera) is excellent

---------- Post added at 07:29 AM ---------- Previous post was at 07:20 AM ----------

If you bought the phone early on like myself and many others and you unlocked your bootloader like myself and many others then treble is the last hope for this device on this forum..

If you didn't unlock then it's too bad I'm afraid.

I agree though Huawei suck.

---------- Post added at 07:36 AM ---------- Previous post was at 07:29 AM ----------

For the people who have unlocked their bootloaders, let's give the treble ROMs a whirl.

Copy your data to your computer.

Remove security.

Copy a type A treble ROM to your internal memory.

Grab MindTheG-Apps for ARM64

Wipe / advanced wipe / cache / dalvic / data

Install ROM

Install G-Apps

Install magisk

Reboot

May need a second boot.

See how long it lasts for you.

If it's more than 9 minutes 45 seconds then you do not need to do anything more.

If it reboots then either you rebranded or we've found a new issue.

In which case it needs diagnosing so grab a logcat.

[MENTION=1915408]phhusson[/MENTION] is our best hope in this regard..

The more the merrier and we'll get it fixed, the p20 pro is a good phone and it doesn't have to be a dead device, just so long as we can get this working as it should..

As I said Reppi has treble ROMs booting as expected and he's reported that they work very well..

It's not over yet ;)
[Huawei P20 Pro Questions & Answers] psycho.b94:
What did you rebrand to? And do you know anyone in the brand you're in now that has had zero issues with treble? I have C185 (the middle east version) and I never rebranded, reason being that I've noticed it's one of the first ones to get updates from Huawei.
[Huawei P20 Pro Questions & Answers] dlads:
I was on the following

L-09

C782

Firmware: 110

I used the non intrusive method from my signature to rebrand as i just wasn't getting updates.

I rebranded to the one in that thread which is the following.

L-29

432

Firmware : 120

I have now updates to 152 officially for the 432

But a fellow XDA user, reppi has the actual 432 L-29 device and he can flash treble ROM's and he doesn't get random reboots in any way at all.

I've tried every single different way of flashing and wiping, even formatting, flashing via fastboot, avoiding g-apps, installing different g-apps, magisk / no magisk.

It just doesn't stick and will reboot between 6-9 minutes.

I think it's ramdisk although i could be wrong.

I'm going to go back if 152 is available for the L09 782, the benefit of rebranding honestly hasn't been wroth the potential risk of a brick, i wish i hadn't bothered.

You if you haven't rebranded but you have an unlocked bootloader etc, should be fine with treble ROM's.

Give one a whirl and let us know, you can always roll back via eRecovery and get EMUI back, or even install Lineage from the dev section.

Back up first.

;)
[Huawei P20 Pro Questions & Answers] dlads:
Do you think flashing the ramdisk from the 782 L-09 model will stop my phone booting?

I'd prefer not to go through the process of de-branding again if I'm honest.
[Huawei P20 Pro Questions & Answers] bowlandspoon:
I'm thinking that it maybe worth a shot, you can back the ramdisk up in TWRP yes?
[Huawei P20 Pro Questions & Answers] dlads:
You won't need to it isn't touched during the flashing process.
[Huawei P20 Pro Questions & Answers] bowlandspoon:
If you replace the ramdisk with one from a different region/phone you should back the old one up first.

That's all I was saying.
[Huawei P20 Pro Questions & Answers] psycho.b94:
I've tried Phhusson's v23 before which resulted in random reboots, I've yet to try version 24 or 25 yet and for now I'm testing EMUI 9 beta and it's a bit of a hassle to roll back to EMUI 8 right now as because there is no root and twrp cannot decrypt data, which makes it even harder to try a treble rom right now. I'll try it soon enough though.
[Huawei P20 Pro Questions & Answers] dlads:
When was this? If it was before last month then the latest fixes weren't implemented so try again pal.
[Huawei P20 Pro Questions & Answers] bowlandspoon:
So last night I flashed Pixel Experience Treble ROM and to my surprise I've had no random reboots.

I can't seem to enrol a fingerprint however. I tried Phh-Treble, Havoc (8.1), and Pixel Experience. Like I said no reboots on any of them, but couldn't enrol a fingerprint. Also on Havoc I couldn't flash GApps due to there not being enough room on the partition, common issue I know but I couldn't fix it.

I know a lot of people are getting random reboots so if I can help with uploading certain system files etc please let me know.

_________

My flash method if it helps...

Reboot to TWRP

Perform a standard Wipe (factory reset)

Flash the IMG to System partition

Reboot.
[Huawei P20 Pro Questions & Answers] dlads:
You're using the wrong version of G-Apps, flash MindTheG-Apps.

Fingerprint is a known issue.

Great that you've not had reboots..

Have you rebranded?

What other issues have you seen?

From what I understand, the treble ROMs work for the most part.
[Huawei P20 Pro Questions & Answers] bowlandspoon:
Pixel Experience comes with gapps pre installed.

Are you saying that using mindthegapps will solve the fingerprint issue? Or are you saying that I won't get the storage full issue?

Yes I have rebranded. Same as you. UK to C432. Model number actually states "CLT-L29 8.1.0.131 (c432).

At work at the moment but will have a proper look this evening regarding any issues. All seems good so far.
[Huawei P20 Pro Questions & Answers] dlads:
What I found that with mind the G-Apps, I didn't have the storage issue.

Fingerprint issue is common across all treble ROMs on the p20 pro..it's possible that the lineage dev here in the p20 pro forum will know how to fix it but if he's willing to divulge that information I couldn't tell you..

---------- Post added at 01:42 PM ---------- Previous post was at 01:22 PM ----------

Oh crap you have rebranded???

Did you try Havoc, Omni or RR unofficial?

I'd be interested to see if you get a problem with them ROM's, i genuinely want to flash Pixel Experience now.

Appreciate you letting us know.

We should get a thread together of what works and the changes between versions, centrally so other P20 Pro users can collaborate and perhaps get some things fixed.
