Downgrade from Pie

Hy,

I just downgraded to 156 firmware using unnoficial TWRP, an USB On-The-Go cable + an NTFS USB stick using HuRUpdater.

1. Download and flash TWRP - https://xdaforums.com/huawei-p20-pro/development/recovery-twrp-3-2-1-0-t3779400 (skip if you allready have it)

2. Copy firmware 156 (all 3 files for CLT-L29 from http://pro-teammt.ru/firmware-database/?firmware_model=CLT-L29C432&firmware_page=0) + TWRP + HuRUpdater.zip on the same folder and place it on the USB device (mine was NTFS formatted)

3. Boot into TWRP and connect device via OTG.

4. When you select Install, just choose USB On-The-Go, then HuRUpdater and after some errors, you will boot into Emui 8.1.

5. Boot into system, then enable developer options and USB debugging and after that just reflash original recovery (from the update.app within 156 firmware) in ADB and after it boots to Emui reset to factory defaults.

6.You should now be fully downgrade on Emui 8.1

Cheers

Ah it turns out the guys script from the link above was incorrect. I've successfully downgraded to 152 now and all is good :good:

Good info for future reference though!

For those that have installed Pie beta would you recommend upgrading to it or wait until the official build is released. Seems to be a mixed batch of opinions?
[Huawei P20 Pro Guides, News, & Discussion] giovanni_97:
For BLA-L29??
[Huawei P20 Pro Guides, News, & Discussion] JamieD81:
I've had zero issues with pie and can't figure out why so many people want to downgrade.

Finally thank you so much bro, now my p20 pro works again. :D

First of all, thank you for this! I own a CLT-L29 C185, I suppose this method doesn't work till I rebrand my device?

[Huawei P20 Pro Guides, News, & Discussion] psycho.b94:
Followed all steps and flashed successfully without any issue, thanks once again! A few bugs here and there but definitely see a slight bump in gaming performance, getting consistent fps with very little drops. Definitely an improvement.
[Huawei P20 Pro Guides, News, & Discussion] MrDanMak:
Probably quite a trivial reason, but I missed the ability to use Google Pay (I use it a lot) so I wanted to go back to current full release software and re-lock my bootloader.

Hopefully it won't be too much longer until official release.

Hey,

First: Thanks for the Tool and the HowTo.

Second: Today it was the first time that i heard something about "FRP". So i googled a bit and find out what "FRP" is and what is does but i don´t know yet, what kind of trouble it could provide if I update to Pie with this method. If I get it correct there should normally no problem if I update to Pie. Can anybody tell me a scenario where "FRP" comes in?

Thanks.

Guys, ATTENTION! :p

I updated to Android P successfully. So far so good.....(Info) I'm not a newby on rooting, but on Huawei ;)

Please tell me, that when I wanna go back from Beta-Update to recent shared Version, I just have to Do a full Firmware-Reset or something. Recovery by erecovery surely not works because bootloader changed during update.

Thanks so much, chiccaaaaaaas :laugh::cyclops:

I have a P20 (EML-L29 C432 .164).

I'm posting here because there's almost no reaction on the P20 thread.

I tried to flash the beta emui 9. I ran the script. Everything went well until my phone rebooted to install the files but then the message "installation failed" appeared. I download the files again but still the same message?

What could be wrong?

Man, I unlocked my bootloader and everything. But now only root is needed. How can I root my P20 Pro with Pie ? Because nobody actually said how. Please reply fast because I need it really fast, big thanks.
[Huawei P20 Pro Guides, News, & Discussion] youtuber123:
Nobody said how because actually you can't root pie for EMUI 9.0
[Huawei P20 Pro Guides, News, & Discussion] Pretoriano80:
I hope your life doesn't depend on it, because right now there's no root solution for EMUI 9.
[Huawei P20 Pro Guides, News, & Discussion] SUPNYUS:
I managed to install Magisk via ADB with TWRP, installation succeed (But with 17.1 it says error) and when I restart the phone an check for the root, it says phone not rooted (with root checker). Same with magisk manager. Should I flash SuperSu ? I didn't use this one since my P9 lite so I don't know if it still works
[Huawei P20 Pro Guides, News, & Discussion] josdehaes:
You really don't understand do you: there is no root solution at the moment because Huawei implemented system as root in emui9. This means there is no longer a ramdisk where magisk could do its thing. We'll have to wait and see if the devs find a way around it but I wouldn't hold my breath.
[Huawei P20 Pro Guides, News, & Discussion] SUPNYUS:
Okay, thanks man, I didn't understand that. But I flashed the Nocheck revocery and this looks like the stock one, so if I put the update.app in the dload folder, it will install it without checking if the firmware is available to install, right ?

Oh and what if I try to flash system.img with fastboot to update from 47 to 106
[Huawei P20 Pro Guides, News, & Discussion] josdehaes:
Why not just use this tool? It updates more than only the system partition.

Well with this tool you can not upgrade beta 1 to beta 2 as it requires root. But I saw another guide that can directly update from beta 1 to beta 2.

Hello everyone

My GT-p5110 start during few seconds and restart indefinitely.

Explanations :

the tablet arrives at home screen, then google play store stop but i can use the tablet few seconds. Play store stop 3 times then the tablet reset. I activated usb debugging during the few seconds i can use it to flash twrp but when the p5110 restart the option is inactive. twrp was for backup my photos by mounting sdcard. After i decide to do a factory reset (and too bad for photos). I went to recovery mode, did the factory reset (all seems good) and restarted.... but nothing was erased.

Any ideas ?

Well the updated adapter to fit the 2018 SM-R325 Gear VR arrived today all smashed to S and I hope it works to begin with (doesn't seem broken) and it barely looks any different than the Note8 USB Type-C adapter. The inner molding is slightly deeper and more rounded but the actual width is about the same. The Type-C connection is a little more angled and there's a N9 stamped on the side of the adapter. If I had my 512gb Ocean Blue Note9 I would test the fit, but Samsung dropped the ball just like they did the padding in the packaging for this adapter.
[Samsung Galaxy Note 9 Accessories] eaoosa:
Thanks for the info Mosely, what number or site did you go to request one?
[Samsung Galaxy Note 9 Accessories] BigMosley:
I simply went on the Samsung+ app and hit the large + at the bottom right and selected Text Chat. Just say you have the SM-R325 Gear VR and you need the new adapter to make your Note9 fit. It's free of charge but I've read some agents asked for your Note9 IMEI to verify you own the phone, they didn't ask me this though.
[Samsung Galaxy Note 9 Accessories] nrage23:
I used the Samsung + app also and they did ask me for my IMEI. My adapter arrives today.
[Samsung Galaxy Note 9 Accessories] eaoosa:
Appreciate the info guys.

No problem, this is how we make XDA the great place it is. Just smash that "?Thanks!" button buddy.
[Samsung Galaxy Note 9 Accessories] netnerd:
why makes it so difficult, have to chat to get it. why cant they just list it at 1 cent and let people order it
[Samsung Galaxy Note 9 Accessories] BigMosley:
Really not that difficult, took me a whole 3 minutes on the chat.

Makes sense to me. Money-wise why not just supply the adapter to the people who ask for them, instead of just giving them away to anyone and everyone and having to make more than probably needed.

I'm working on the gear vr shaving off as well to make the phone fit will upload pics. SMH Samsung the things I do for VR gaming.
[Samsung Galaxy Note 9 Accessories] BigMosley:
So you're saying the new Note9 adapter you got from Samsung didn't fit your Note9?
[Samsung Galaxy Note 9 Accessories] killa57:
I'm saying the new adapter didn't fit the gear vr that Samsung sent me. Even when I cut the adapter to custom fit it to the gear vr the note 9 still didn't fit in the gear vr cause of the size of the phone.
[Samsung Galaxy Note 9 Accessories] BigMosley:
Do you have the SM-R235 or an older model?
[Samsung Galaxy Note 9 Accessories] killa57:
Wow I just checked the gear vr and it is a older version sm-r324. Wow off by one number makes a difference with it all said and done. I just made it custom fit the the note 9 and I'm content now;)
[Samsung Galaxy Note 9 Accessories] Organoon:
Hey guys, I asked for the adapter on Samsung Members (Samsung+ app version EU) and it was pretty hard to get a assistant who was agree to send it to me (On my gear VR box I don't have the precise model, it just says SM-R324, and not SM-R324-xxxxx)

On my third try I've finally got a guy who understand the situation and ask for IMEI, SN from both note 9 and gear VR and all information for delivery.

Now I just wondering how long it takes for you to get the adapter ?

I'm pretty excited to test my note 9 on my gear VR, and I can't wait for it especially without having any tracking of the adapter.

It has been 6days since I gave my info to the chat assistant, when can I expect the adapter to arrive ?

Edit : 325 and not 324* I mistyped on my post sorry.
[Samsung Galaxy Note 9 Accessories] Organoon:
Hi guys ! Just an update to let you know that my adapter finally arrived today ! It took 14days for me to get it after I gave my info to Samsung. If anyone is in the same case now, you know you'll have to be patient.
[Samsung Galaxy Note 9 Accessories] henklbr:
Just for your information:

This adapter is for the SM-R325, NOT for the SM-R324 ! ! !
[Samsung Galaxy Note 9 Accessories] Organoon:
Hi ! I'm sorry you're right, I just mistyped the number, but my story is the same. They didn't want to send me the adapter because I didn't have a special number following "sm-r325".

Anyway, I finally get it and it works perfectly. Sorry for the inconvenient, I didn't realize I have wrote the wrong reference on my post.
