TWRP Xperia 1
By Ferdian™






Hello everyone.

I'm trying to build TWRP for Xperia 1 on based android 11.
which one this device does not have TWRP support for android 11.

I've tried several TWRP and unfortunately
can't Install zip or for backup anything.
even I can't booting into system.

so I tried to build it and booted successfully,
I've tried it on my own device (Xperia 1 DoCoMo) and it worked fine.

so, if you want try to Install it,
don't forget to prepare your original boot.img,
just in case if it can't booting into the system. :)

TODO : decrypt Internal Storage,

Sorry, it seems I still can't do decrypt Internal, I've tried various ways, even tried ask for help to official twrp. but still no solution yet. and although no one supports me too, at least I've build twrp to make it easier for xperia 1 users and this is my last build ...
I also previously intended to try porting it for xperia 5, because someone tried to install it on xperia 5 (V.3 Version). but it bootloops when rebooting the system. Unfortunately I'm already tired before trying to porting it
maybe later there will be more great and real developers to make twrp for this device

if there is a path problem in fstab, you can Unpack it and fix it for yourself. or even you can experiment to decrypt it.

2. Internal storage still encryption what will this actually affect?
nothing, only can't read your file in internal storage from twrp. it's like a data protection.
no effect at all after booting

Just because we there few developer and ROM for us :.(

yep, I think very few interested people like this device. especially the Japanese variant, it's quite expensive to change UBL no to yes

Thanks a lot for this. I left this phone last year because a relative lack of development. Plus my model, Softbank, didn't get the upgrade to 11. But with this I might make it my dedicated emulation device . Thanks a lot!

Still hope for a full functional custom ROM for our Xperia 1
Isn't there already a discussion in another thread about Rom which is quite stable, such as evox etc.

but at least we got a twrp for it. may open new opportunities.
also. the drm keys seem to be a big issue for most
yep, I hope so.
and btw I think the a11 is not too heavy for the drm keys. not like in android 9 and below, which there will be a lot of trouble

Yep anytime, I think this phone is pretty good too. unfortunately very few developers are interested. and isn't there android 10 can use Sjll's twrp?

I have to test the evox when I got holiday cause Xperia 1 is my daily phone. So I need some times to deal with it.

May I ask if how did you unlock your bootloader on a docomo unit? Because I have a Xperia 1 Docomo unit also. Thanks in advance

    Sorry I didn't try the mtp function when using Evo or the Stock, so I really can't tell.
    oh okay, and because Rom Evox and Cherish is different from my device tree, it might be very influence too.
    but maybe I'll try to make a little change later

    The link seems to be broken. Tried 3 different browsers and can't open it
    sorry I removed it. will make another build
    cause after format data, storage still encrypted

    The SD card (fat32) works.
    Tried flash Magisk, works.
    Didn't try anything else, but it looks legitimately great

    EvoX 12.1 on J9110 (Global ver)
    OK, thanks for the report. I've fix some partitions and upgraded to TWRP 3.7.0_11. still working on internal decrypiton.
