Poco X3 is no longer viable
-
@aimar Thanks for the tip, and for posting that link! I'll try it out. Meanwhile my existing phone, Oneplus N10 got VoLTE support, and my need for a different phone evaporated.
But I'd love to get UT working on that device.Good luck getting yours unlocked! Seems it may be more a question of luck than anything else

-
@wally In this other Reddit post a guy says that "... Xiaomi only allows 2000 people per day (unlock requests) which is ridiculous. Took me 3 more days of randomly opening the app & requesting an unlock. It finally happened. Very randomly."
I don't know if its true, but it can explain why some people get it and others don't without any reason.
-
@aimar Yeah, I'd read something about that. It resets at a certain time of day, China time (one big time zone).. not sure if it's midnight or what. Worth looking into what time the daily quota resets.
-
@wally this thread recommends GMT+8.
Today I got the phone. It's huge. I miss my 4.5" screen. Why do they make only big phones?
Anyway. It is a officially (xiaomi) refurbished phone. MIUI Global 12.0.8 Stable 12.0.8.0 (RJGEUXM) and Android 11 (RKQ1.200826.002). I have not update anything.
I created a Xiaomi account, but have not yet linked it to the phone. Digging in it, I switched and option called "OEM unlocking" (or something similar, my phone iz not in english). That's it? Is it alteady unlocked without any waiting nor SMS code required? Am I so lucky?
There are some USB options, but think I enabled the "USB Debugging" option.
There also is a "MyUnlockStatus" option but since requires some permissions I haven't accept them in case
As mentioned in the device description I downloaded MIUI Build V12.0.9.0.QJGMIXM. I have to learn how to flash it to the phone though. Would it be enough? -
-
Thanks @moem.
What a shame. All is to misleading.
So I guess I will link the phone to the Xisomi account, etc, etc. However my SIM card has not data. It has only calls. I rely on wifi. Why must it has data? This requirement is quite strange for an ignorant like me. Does not feel trustworthy.
Will keep you posted. -
@aimar Yes, GMT + 8, and notably, that linked site confirms that it indeed resets at midnight in China, not some other time of day. Useful!
There's an excellent post to help install on Redmi Note 9 Pro and similar devices. While of course there will be differences for yours, like firmware, I strongly suspect the basics of unlocking will be the same.
The other difference is that the post is from 2024, and it seems clear that Xiaomi has made it harder to unlock. But at least this shows you the process: -
@kln_nurv yeah, its xiamoi in general thats not viable anymore, and I don't think any new xiaomi device will be ported. about the poco X3, if it doesn't have an efuse you're best bet is to downgrade to miui 12 with sp flash tool and bootrom bypass, then install a custom payload.bin from an already unlocked phone, i don't have this device but if you want this to still be viable we need a unlocked bootloader dump from a donor phone via sp flash (preferably a full nand dump).
if you get me a full nand dump i can probably create a small bootloader unlock "rom" for you to flash with sp flash.just be ware that the nand dump if it a full one should not contain these: protect1, protect2, nvcfg, nvdata, nvram because they contain IMEI, bluetooth address/MAC, ect.
protect1/2 are sometimes called L/R instead of 1/2 in the scatter file. -
Account set and paired to the phone.
@chromiumos-guy Honestly I didn't understand a word
@kln_nurv The last link provided by @wally states "At the end of 2024, Xiaomi will start to check the regions in which your Mi account is used. For example, if your phone or tablet is designed for the Chinese domestic market, you will only be able to unlock the bootloader with a Chinese account.
If you try to unlock the bootloader of a Chinese phone from a global account, youβll get an error: βThe place where the account is registered does not match the place where the phone is soldβ."
I hope Global accounts don't have the weird limitations you mentioned.
The MiUnlock version from the Ubports devices site didn't work properly in my laptop, so I downloaded the last version from the last link provided by @wally. I can launch the app but cannot connect to the phone. "Mi Unlock not connected to the phone. Possible driver issue or incorrect application folder name. Also possible bad smartphone-PC connection due to poor quality cable." I guess it is the cable.
I realized that i skipped "Submitting an application through the Mi Community app.". Is it necessary? -
It was the cable. I used another one. Clicked on the gear at the top right side of the window. I clicked on "install driver" "check" button. A new window popped and ask to replug the phone. I did so and a spinning wheel indicated some activity and the phone was connected. I tried to unlock, the phone was verified, and i got a message asking to wait 143 hours. Next week if I am lucky I can be back on ubuntu-touch.
The first time I opened the MiUnlock app, I had to login in my account. I did so with and email and a verification code send to that account. Afterwards it asked to register the phone number and I got a SMS to that number almost instantly. SoI had no problem with that SMS verification.
