[Razer Phone Questions & Answers] Dirrtydog:
It's a fire an miss actually. Sometimes it reconnects automatically with the car's unit (alpine aftermarket) and sometimes it doesn't. I had noticed that if I get in the car for the 1st time today (for ex), it won't reconnect back and i have to cycle around the input in order to "kickstart" the reconnecting process. If I make a stop along the way, stop the car, get out (thus interrupting the connection) and getting back after a while, it will reconnect automatically without any issues. I'm not even taking it out of my pocket. But this scenario is happening since day one, not necessarily from the last update.

On the other hand, I got a smartband (coincidentally after the last update) and now, while the smartband is connected via BT, when I turn on my BT wireless headphone adapter, it won't re-connect anymore (simultaneously with the smartband) and if it does, it's without media playback. As a workaround, I have to 1st turn off the smartband, clear the BT of any active connection (And also any other device with media playback capabilities), turn on the BT adapter so it will connect full, then turn the smartband back on. And not always works like this.

So, I do have on an off issues with the BT stability and connections with various devices, not just car unit.

Strangely though my smart watch connects no problem and the stereo in my motorhome was connecting at the weekend. It's just the car ( a Vauxhall Astra) that refuses to connect unless I delete and re pair....
[Razer Phone Questions & Answers] kdogguk:
I can't get music to play with Spotify or YouTube. The phone connects fine, shows song info but just won't play no matter what I try.

The weird thing is that calls work perfectly. Sound through car speakers and mic works. Just doesn't want to play music.

I've tried unpairing, re-pairing, deleting, even factory reset on both phone and stereo. Worked fine before the 8.1 Oreo update. (I'm on 3 UK handset).
[Razer Phone Questions & Answers] Jcoyk:
Im having issues as well, it will connect the first time when I manually connect the phone and stereo to MyLink. It will say connected but (No Media) so i try to pair the media and it disconnects my phone from BT and then i have to delete device and re connect device manually. As well if i leave the vehicle or turn it off then it will disconnect. Not just my vehicle but the other showroom vehicles do that as well. Can someone let me know if there is a bluetooth upgrade or a firmware upgrade that can fix this problem? is there anything that we can do for this let me know. Thanks!!
[Razer Phone Questions & Answers] ArcaneDroid:
I am having the same issue in my bmw.

I can delete the phone and re-pair... But it sucks having to do that every thing.
[Razer Phone Questions & Answers] rudebwoy03:
also having issues as well. It connects to my headphones and the after market HU in my truck but it will not connect at all to the factory HU in Genesis Coupe. I have tried to delete and re pair and still nothing.
[Razer Phone Questions & Answers] tambukey:
So currently it all works for me with the latest update. It definitely takes a little bit longer than normal though. Not sure how long some of you waited, but compared to my old phones it feels like an eternity during the time it doesn't connect. I also use a smartwatch and it is always connected to that. If you guys need or want any files, let me know. I'm currently waiting for a usb-c to usb-a cable in the mail, so once that is here I can try to help.
[Razer Phone Questions & Answers] ericpeacock79:
I think this is all more of an Android issue. I was having most of the exact same issues mentioned here on my LG V20 on Oreo.

I just for a Razer Phone 1 off eBay this week. I did the Pie update and within a day, the bluetooth issues have returned. Sometimes phone won't connect to car stereo - sometimes reboot stereo, sometimes toggle phone bluetooth off/on, or sometimes just wait 10-30 seconds. Doing the same showing info on car stereo display, but no audio transmitted. I also had similar issues using a OnePlus 3 with both Dirty Unicorns and Resurrection Remix Pie ROMs. I was beginning to think it was my car stereo until I read the comments on this thread. Seeing so many others having the exact same issues on factory and aftermarket stereos (mine is an aftermarket), and knowing it's happening on different devices and both Oreo and Pie , I'm thinking it's an Android 8 and 9 issue.

Has anyone managed to get any Treble ROMs working? I tried the 3 from this post but they just cause a bootloop https://www.xda-developers.com/flash-generic-system-image-project-treble-device/
[Huawei P20 Pro Questions & Answers] dlads:
Do yourself a favour and remove your password / pin / pattern as i've just flashed one via fastboot (no treble recovery)

And it didn't work, now i can't get back into TWRP.

Any ideas?
[Huawei P20 Pro Questions & Answers] danielfrancisarthurs:
No new treble ROMs work with our P20 pro's.. its the same for me which is why I'm back on stock for now... As every new version of treble ROMs I have tried do not boot for me they just stick me in a boot loop as well, its the same for the new version of lineageos.. Not sure if it will ever be fixed in the future though on newer builds considering the whole Huawei locking bootloader permanently thing... will probably put developers off Huawei phones all together...
[Huawei P20 Pro Questions & Answers] dlads:
How did you get back to Stock? I have no OS now at all lol, i'm in limbo
[Huawei P20 Pro Questions & Answers] danielfrancisarthurs:
Erecovery I used.. when booting and you get the unlock boot screen it will tell you to hold volume up I think for 3 seconds to go to erecovery and then just download and restore stock firmware and recovery and let the phone do it's work!
[Huawei P20 Pro Questions & Answers] dlads:
Yea i used eRecovery a little earlier myself, we really need twrp which actually allows decryption or even twrp which allows treble

Either that or decrypt and use no verity, haven't bothered with all that yet.

After today though, jesus i'm thinking about it, i literally ended up with nothing, all my wifi networks in work need a second log in, something which eRecovery can't offer.

Completed it when i got home.

Have you managed to install any treble roms? Has anybody?

I don't think it's possible on my device in it's current state, i tried TWRP, Fastboot, several different roms on both and nothing.

Spotted this earlier, might actually work on our devices, what do you think?

https://xdaforums.com/huawei-p20-li...rp-3-2-1-0-t3782866/post76668571#post76668571

It's a treble recovery from the p20 lite forum, similar device, might work, anyone fancy trying it :D

PS: If i flash this can i just flash my Unofficial TWRP from our forum should it not work? Or can damage be done?
[Huawei P20 Pro Questions & Answers] danielfrancisarthurs:
I have no idea! I assume the issues are because of twrp or something in that area.. I have tried flashing system images via fastboot but for some reason I get errors trying it.. I'm not sure what the main issue is on why they don't boot but i would strongly suggest to not try flashing any twrp that's not specifically for our device as you could brick or even break your phone!
[Huawei P20 Pro Questions & Answers] dlads:
Apparently you don't need to use twrp at all, I've successfully flashed system images, via fastboot, but they've never booted which is horrible because there's just nothing else here.

In regards to flashing twrp, again apparently if it goes wrong then we can just flash the stock recovery, personally I think flashing another functional recovery would work too. But in all fairness the one in the p20 lite thread doesn't work any more than ours does in the pro thread.

Just hoping things move along.
[Huawei P20 Pro Questions & Answers] danielfrancisarthurs:
Yeah I'd assume so.. I haven't been able to flash any image via fastboot but I'd assume it's the ROMs not the recovery.. anyway just heard that Huawei have released the Source code for the P20 so maybe it might be good news for the treble ROMs if they were to implement fixes for the boot loops!
[Huawei P20 Pro Questions & Answers] dlads:
Sounds superb on any other flagship in the world, really hope this one picks up, it's a great device, never been happier with a stock ROM before, I think with all aosp lineage ROMs there's going to be huge issues fixing the cameras. Twos hard enough, 3 lol very hard.

Not trying to be negative just a bit worried is all
[Huawei P20 Pro Questions & Answers] Paz9:
Can someone take a video of the boot loop

There's actually a method to how this phone loops. It could indicate the problem
[Huawei P20 Pro Questions & Answers] danielfrancisarthurs:
Not sure about the camera but there's always ports into the future.. anything is possible! But could be a while till we are able to be booting any decent treble ROMs.. but then again as the source code has been released it may not be that long.. depends how quick the developers for treble react and whether or not they have a Huawei device to work with to fix our issues..

All we can do is hope!

---------- Post added at 11:12 PM ---------- Previous post was at 11:09 PM ----------

I will give it a try flashing a system image again tomorrow and take a video of it if I'm able to! But someone else needs to give it a try too just incase I don't get time please? The best way I can explain it is once the system.img is flashed in twrp I restart system as normal and it boots up normally with the Huawei logo when phone turns on then goes to bootloader unlocked screen and press different buttons for different options to boot from or wait until device boots normally so I wait for it to boot normally and soon as I get past the unlocked bootloader screen it just instantly reboots and just keeps rebooting doing that!
[Huawei P20 Pro Questions & Answers] dlads:
What signs are you looking for?

First time I tried it went from the press up for 3 seconds page then black, then vibrate then back to solid white Huawei, repeated 3 times until eRecovery asked to wipe.

For me after that point I flashed another and it went through to a lower case android sign, changing times from white to silver in a flow type effect, it stayed that way for around 10 minutes then back to eRecovery, flashing another treble ROM did the same thing.

Currently running: c782, 110, L09 p20 Pro, unofficial twrp and magisk.

The initial installation was via twrp, subsequent flashes wereb performed via fastboot.
[Huawei P20 Pro Questions & Answers] danielfrancisarthurs:
Thats pretty much the same for me of what happens! Just boots then get a boot loop and black screen and back to the Huawei logo again from the start.. never able to actually boot a rom..
[Huawei P20 Pro Questions & Answers] dlads:
I thought the idea of treble was to match the Android version?

Seems as though it's trial and error with what's allowed.
[Huawei P20 Pro Questions & Answers] danielfrancisarthurs:
Treble is still a work in development at the moment.. it doesn't help as well that Huawei are being assholes and making developers want to stay away from Huawei completely due to the whole locking bootloader thing but hopefully there are a couple of developers out there that keeps our devices in mind and hopefully means we will see a fix for our devices soon.. but when that is I have no idea..
[Huawei P20 Pro Questions & Answers] dlads:
Aye it looks grim, that being said though, the stock ROM with a few tweaks is excellent, I've never once liked a stock ROM before on any device.

Root is easy, twrp is workable, bootloader was a breeze, we only have one actual ROM (LOS) but by all accounts even the p20 Pro camera works exactly the same on that, with that in mind what more do we need?

Course I'd like to be up to my neck in baked ROMs but if you're honest we truly only stick with one or two, as it turns out the two we have are pretty great.

Maybe I'm being optimistic
[Huawei P20 Pro Questions & Answers] dlads:
Just had a reply from another thread, quite interesting...

Yes, lol

the way i did it was with a stock recovery and system image

boot into erecovery and do a factory reset or a fastboot -w

boot back into the bootloader

flash the system image for the treble rom

then go into erecovery and do a factory reset

and then it should boot no problem at all

twrp cant wipe properly on treble roms

ive done the same on my p20 lite today, all stock and no issues booting at all

let me know how you get on

:good:

Hi, i have been occupied all day to get this to work, it just doesnt. i have followed the exact steps you layed out but when i try to factory reset after flashing the treble rom using fastboot it just gives me the error: "reset failed". I have tried using other GSI images but none work, had to restore my phone thrice because of this. I dont know what is the issue. These are the steps i followed:

1. Went completely stock ( no twrp or root )

2. Successfully factory reset my device.

3. Boot into fastboot and then flash a treble GSI.

4. as soon as the device turned on, went to the recovery to attempt a data wipe but at around 60% of the process completion the recovery gives the error with a red exclamation mark enclosed in the circle.

My device is a CLT-29 (C185). Was really looking forward to treble as my previous device was a Oneplus.
[Huawei P20 Pro Questions & Answers] dlads:
Ah the OnePlus , got the 5 still with me, great phone, great development.

Perhaps if your device was debrand? Could that be it?

Maybe it's just not meant to be
[Huawei P20 Pro Questions & Answers] mrabcx:
If you search for p20 pro in the main Treble development thread

https://xdaforums.com/project-trebl...-development/experimental-phh-treble-t3709659

then there are at least two users who seem to have got Treble boot on the p20 pro.... Get in touch with them to find out what you guys are doing wrong (and then let us know).

Btw, a new version was released today "- Rewrite Security Patch Level for Android 8.1 devices, and A/B devices as well. Should fix boot for some devices.". Could it be that ?
[Huawei P20 Pro Questions & Answers] psycho.b94:
Ahaha yeah i had the 3t and then i switched to this because i felt comfortable with Huawei. Even so i miss near stock experience is and now that we have a stock camera app port its pretty much worth switching if you like stock android. I don't know I've been thinking about rebranding too but it doesn't seem logical. The phone has treble support so it should work regardless of the model, but who knows
[Huawei P20 Pro Questions & Answers] reppi:
So I successfully booted several GSI (RR, DotOS, Lineage) without big issues. Simply wiped System, data, dalvik, Cache in inofficial TWRP and flashed the .img and GApps afterwards. Had to modify GApps installer.sh as described in another thread because it didnt't recognize the P20 Pro as A-only device. After that it flashed fine but I had to wipe data and flash again after boot because GApps were not installed at first try somehow.

What still keeps me from using GSI is random reboots every ~10 mins. Happened with every ROM I've tried so far.

Device: CLT-L29
[Huawei P20 Pro Questions & Answers] dlads:
That's excellent news.

What device do you have and what ROM / firmware?

It'd be great for people to know specifically then the OP can update this thread so we know what works and with what device /firmware.

Thanks.

---------- Post added at 11:27 AM ---------- Previous post was at 11:25 AM ----------

For me I'd want the latest firmware, the camera port is from 128, I've been working with the guy who wrote the debrand guide to make it a lot easier.

I've just not had time to get around to it yet, but it's on my list to do.
[Huawei P20 Pro Questions & Answers] reppi:
I'm on CLT-L29 8.1.0.128 (C432) and using unofficial TWRP.

Flashing Lineage from our ROM section now and will report back if that works better.
[Huawei P20 Pro Questions & Answers] dlads:
Yea all we need is the device model, firmware, ROM and variant, de-branding should allow us to match up then we're all good.

Once I've rebranded I'll commit to getting this working.

---------- Post added at 11:31 AM ---------- Previous post was at 11:30 AM ----------

Cool, thank you.

So a rebrand is necessary I guess.

Least we know that it'll help with treble.
[Huawei P20 Pro Questions & Answers] reppi:
You're welcome.

At least two other guys from our Telegram Support Group on same branding have successfully flashed GSI but also encountered random reboots unfortunately. So definitely a P20 Pro GSI issue as other devices dont seem to have those reboots.
[Huawei P20 Pro Questions & Answers] reppi:
The Lineage ROM as flashable zip is working fine! Of course still no stereo speakers and USB c headset not working but other than that a pretty good daily driver.
[Huawei P20 Pro Questions & Answers] dlads:
I'm now on the same myself. Will give it a work at some point, can't seem to get twrp working no more though? Its a mad one.
[Huawei P20 Pro Questions & Answers] psycho.b94:
If anybody is still wondering about this just got an update on p20 pro issues with the Treble rom developer, he has confirmed that random reboots have been fixed as of the latest version for our device. Will be testing soon.
[Huawei P20 Pro Questions & Answers] dlads:
Good to know but honestly I've never manged to get one to boot in any way.

The P20 pro forum are in desperate need of a decent guide.
[Huawei P20 Pro Questions & Answers] reppi:
I've tried some ROMs already a few weeks ago and I've never had any boot issues. The only problem was random reboots but that has been solved a few weeks ago already.

Tried havoc and RR and they worked fine beside those usual custom ROM issues.
[Huawei P20 Pro Questions & Answers] dlads:
What state is your phone in when your flash it? Are you already rooted? Any mods?

What was the process you used?

What twrp? Did you wipe and what did you wipe if you don't mind me asking?

Once I've got it sorted I'll write up a nice easy guide, we sorely need it.
[Huawei P20 Pro Questions & Answers] reppi:
Sure no problem.

I'm running latest EMUI but that shouldn't matter.

Running unofficial TWRP. Official does not work because it can't decrypt storage. Root doesn't matter.

Remove any security feature like fingerprint, face unlock etc before booting to TWRP. Otherwise you can't get in.

Make TWRP backup and save it to PC (recommended).

In TWRP wipe system data dalvik cache.

Flash ROM.

Flash Gapps (if you get failure try version shared in telegram group).

Flash magisk v16.7 (optional).

Reboot system.

Done.
[Huawei P20 Pro Questions & Answers] dlads:
Yea I did that and it didn't work.

Plus you have to flash the IMG to system btw. Or so I've read. I think there are some bits which have been missed out otherwise it should work right?

Literally all the info has to be laid out or it won't work for everyone..

I read that you can't be rooted also? But it hasnt mattered to me..

Do you format data or do you wipe?

What version? A or B?

Did you flash anything else?

What treble ROM did you flash?

I'll give it another shot but I've been really unlucky up until now..

Appreciate you telling me what you've done though.

If there's anything you've missed out. Please fill in the blanks..cheers.

[Huawei P20 Pro Questions & Answers] psycho.b94:
So I tested it out and thankfully the Rom booted up nicely and everything was smooth and good. I used unofficial TWRP to wipe data and flash the Rom. Phone rebooted on its own upon first boot but booted up nicely on the second boot. However, 15 minutes later the phone rebooted randomly and this happened at least 2 more times. Additionally, I had an issue with fingerprint not getting through properly, the progress bar would stop at the final attempt the fingerprint. Perhaps I did not wipe properly and could be a fault of my own because neither Magisk or SU were working. Perhaps it is that fault which is causing the reboots. Also I noticed that type c earphones don't work and the speaker quality is not on par with EMUI and also seems to be mono instead of stereo
[Huawei P20 Pro Questions & Answers] reppi:
That's the typical treble rom issues. Fingerprint is not working etc.

It seems you're using a rom that has not been updated yet because in newest roms the random reboots are gone. Try official RR or havoc OS. Those run fine
[Huawei P20 Pro Questions & Answers] dlads:
I've installed omni ROM which is fantastic. Couldn't get RR to boot for some reason. I'll try another. Which one are you referring to?

Unofficial or official?

Thanks for giving me the nudge to try these out, feel like I've got the phone I should have had.

Appreciated.

Any idea if omni has been updated?

There's so many tweaks which is amazing.

[MENTION=1096076]reppi[/MENTION] the havoc build which appears to be the latest does actually randomly reboot, RR doesn't look like it has a very up to date ROM so not sure where to download from??

Where are you finding the ROMs that are up to date??

Lol no wonder 25th July security patch and build date, where are the latest versions?

The resurrection remix official ROM from 18th August 2018 does randomly reboot.

What were you referring to pal?

[MENTION=1096076]reppi[/MENTION]

Have you actually installed these ROMs?

Would the version of gapps matter?
[Huawei P20 Pro Questions & Answers] reppi:
Well that's weird because I tried that ROM a few weeks ago. Official RR and Havoc OS. Both worked without reboots for me.

Try this: https://github.com/phhusson/treble_experimentations/issues/106

Ok so the long and short of it is to delete system/bin/uncrypt ?

Legend if so, thanks pal. :good:

---------- Post added at 06:19 PM ---------- Previous post was at 06:12 PM ----------

Nah still rebooting..

I'll flash the emui back so it's stock.

Then with all the official and stock files in place I'll reflash a GSI and see how that goes. Might be magisk or even anything modified from root etc

Not sure what else to think.
[Huawei P20 Pro Questions & Answers] psycho.b94:
It seems both you and I have the same problem when it comes to this, while others report no issues at all. Last time it was bootloops while others reported successful boots but occasional random reboots. Maybe it has something to do with our particular models or regions, who knows. Let me know if you figure anything, I'll give it another go sometime soon too
