Hello!
I've just bought Oneplus 3 specially to install Ubuntu touch.
Where I can ask questions about installing and usage
(stupid and advanced).
I've watched tutorial videos(ubports installer) and read the documentation.
But I still have a lot of questions and suggestions.

Thanks in advance.
And sorry if this is not the place to write about it.

@Kyrylo Here us exactly the right place. No question us stupid we all learn new stuff by asking and finding out.

Hi!
I suspect that there are many owners of OP3 here.
I have a few questions about installing Ubuntu Touch regarding the ability to return to the stock state:

1. When installing Ubuntu on OP3, I have to install TWRP, so where can I download the stock recovery for Oxygen OS 9.0.6 (preferably from some reliable sources)
2. Could you tell me how to deal with encryption, I mean when installing stock firmware. I've heard that there are problems with it.
   Thanks in advance for any help.

@Kyrylo Hi the stock rom you can download here https://www.oneplus.com/global/support/softwareupgrade

[Kyrylo]

@Xray2000 Hi! Stock Rom is already downloaded, but where I can get stock RECOVERY img to replace TWRP img? I found some on the web but I'm not sure for which version of stock rom.
So... Any help?

@Kyrylo You can try here https://forums.oneplus.com/threads/oneplus-3t-stock-recovery-image.1114082/

[Kyrylo]

@Xray2000 Thank You very much. Could you tell me how i can know for which version of stock image this recovery is, or whether it does metter? And maybe someone has exprience in returning to stock condition and can give me some advices and valid links.
I found a lot of outdated tutorials and broken links so l prefer to ask You help to be sure I'll be able to do everything right.
I will appreciate a lot.

[Kyrylo]

@Xray2000 By the way, I've downloaded recovery from other source than your link earlier. That was recovery for Oxygen OS 4. But sha256sums of both images are the same.
So I don't know if I can trust this recovery and where I can get recovery for OxygenOS 9.0.6 available now.
Any suggestions?

@Kyrylo
You should try XDA dev forums, there are some high knowledge for each androïd devices, including stock softwares.

@Kyrylo I think you should read carefully the oneplus forum for the correct version to download, i dont have play with recovery mostly when i one go back to stock condition i just flash the rom from the oneplus website....

[Kyrylo]

@Keneda Yes, You are right. XDA is the place to ask this kind of questions, but most of their topics is outdated 2016-17.
I hoped to find living help hoped to find living help from living people herep from living people here.
Nevertheless thanks a lot.

[Keneda]

@Kyrylo
Here you will find outstanding living help for UBports ^^
Outdated topics doesn't mean people who did them are dead.
And like said @Kyrylo there is also Oneplus forums.

Here just a few people come back to androïd so very few know or did it.

Hi, I solved the "caller is to quite" issue on my 3t. I had simply to much dirt in the small net in front of the speaker.
Sadly it's not easy to clean. Either open the phone to clean it or take a neel and push a small hole through the left side of the net (quick but rough).
