Question Poco X3 Pro total brick issue - Xiaomi Poco X3 Pro

Hello there. I am using the Device Poco X3 Pro(Bhima) since 14th June 2021. I had several touch issues before and that got fixed on a update. Recently I have been hearing a rumour that indian variant of Poco X3 Pro specially 6/128 is getting hard bricked. If that's true what measurements I can take to prevent it? What's the main reason behind this ? Is there any explanation ? Is there any way to save the device my device by EDL mode if it's bootloader is unlocked? Or this is just completely hardware issue? No matter what I do it's gonna get bricked or not?

Poco F2 Pro and its problems I had

Hey all of you,
I'm pretty new to XDA, but not to Xiaomi.
I am the kind of User that still sticks with MIUI to not risk any broken phone or anything... I've never even unlocked a bootloader or anything...
I was pretty happy with my Poco F1 till my battery life was going even more downhill :crying:
That's when I decided to buy the Poco F2 Pro from eglobalcentral. I was sooo happy when TI arrived... But that feeling quickly changed. On 11.0.2 I experienced a hard battery drain while the phone was off. That's when I updated to 12.0.4(didnt knew 11.0.6 would probably be a better choice).
Now I'm stuck with the Poco F2 Pro that doesn't have a great battery life and problems with Netflix and Amazon Prime
-> Prime doesn't work in HD anymore...
-> Netflix doesn't work in HD and with it broke the mediaserver
You have to love it :/
-> when watching anything of the above, mediaserver drain around 70% of the battery (screen is around 10%( the apps themself at 2 to 5)
Welp those phone were reset the normal way enough times to know nothing will change
My idea was to maybe unlock bootloader, clean install 11.0.2, 11.0.6 or try 12.0.4 again.
But since I'm a total noob at this:
1. Do I lose sensor like I've read a few times when downgrading)
2. Is the re any reliable source to download twrp and is there any guide out there?
3. Can I use miflash for the phone to downgrade aswell? Or will it have complication (does it totally reset the phone?)
4.how to I make my pc find my phone in fastboot mode?
5. Does it make more sense to send it to Xiaomi and make them fix my phone for me?
6. What's a reliable source for Poco f2 pro Roms? The xiaomi.eu website didn't have poco f2 pro in there list, or am I juts blind?
7. Anybody else had any problems MIT miui 12 yet?
If anybody is so kind to help me, it would be Highly appreciated.
Thanks for reading and have a great day
I would suggest to update the phone. Mine shipped with 12.0.3. There was a noticable improvement to whatever the next upgrade was, a substantial improvement changing to eu roms, mind blowing performance and battery improvement switching to MSM- Extended. All guides are very easy to find

New POCO X3 Keeps Hanging

Hey Folks,
I just bought a new POCO X3 a month back (Indian Version) via Flipkart.
I am on the latest version of MIUI 12.0.9 (as per the OTA update).
My phone usage is moderate. No fancy apps, No Games. Still, at times my phone keeps slowing down or hangs.
Is anybody else facing the same problem? I am considering taking my phone to the service center.
Latest update for India is 12.0.10
See if updating it fixes the issue. But it shouldn't be having these issues regardless of update or not.
If you just bought it, have it exchanged on FK. It's better to get a new device than to have it "serviced".

My Poco x3 pro has died... I was watching TikTok and has been caught, passed the black screen and reboot the screen goes blank after the logo of Poco, I can not reinstall the system or anything, it stays the same, osea lets me reinstall the system from fastboot but I can do nothing to reboot.

but the warranty might be over, considering it might be bought before july 2021? then will it be prohibitively expensive to the OP?

Is the device irreparable without changing the motherboard?

Look for a technical service in microsoldering even if it is not "authorized" as long as it has a good reputation and knowledge to do a rework to the SoC and revive your Poco X3 Pro, you can search the YT "Poco X3 Pro dead Solution" and a idea of what to do to the equipment, it should be emphasized that it is physical damage, not software

No it can be repaire , I repaired my poco x3 pro 2 times from a local mobile repair shop but it died again next day of repaire so repairing isn't a permanent solution

In part you are right but on the other hand you are not. I ask were you present when they "repaired" your PX3P? did you see that they raised 3 integrated circuits ram+CPU+UFS? if he left his cell phone and he was not present, maybe they only lifted 1 or 2 of the 3 components or in worse case they only did "Reflow" that's why his Poco failed again

I don't know what they did inside but one thing i saw that they opened several part of mother board they were also aware of this problem i contacted many repaire shop also the person who's working in mi service centre he said that it is not parmanent solution sometimes repaired x3 pro can work atleast 4 to 5 months or less but it will brick again for sure because when it brick it fails multiple part of phone sometime it's cpu , ram or ufs storage itself

that is probally chip reflowing, which is useful for data rescue but will not work long. the chip is not replaced and is bad so a more expensive chip replacing should be worth it.

The "Rework" job when it is done well and completely to the 3 chips does not fail, I tell you this because I have done several of those jobs the oldest 2 years ago not to PX3P but OnePlus 6T and they have never brought it to me by guarantee or because it fails again, I go back and repeat the "reflow" is not a permanent "repair", the "rework" Yes

The only 2 "chip" that can be replaced are the Ram or UFS, to replace the ram you just have to find out the type of LPDDR it is and the bandwidth, nothing else if you want you can put an 8GB instead of the of 6gb or greater capacity, for the UFS apart from knowing the type of memory, voltage that works, you have to copy absolutely all the files from the old one and copy them to the new one, but it is done with a special "reprogrammer"

Question Is my poco x3 pro (global) safe now that motherboard was changed?

So in 15 aug 2022, my poco x3 pro (which i had used for 4 months?) died out of nowhere (edl - no charge light) and warranty changed motherboard (all data is gone :/). This is already my last xiaomi phone ever but I may use it for now.
My question is: after the motherboard change, is this chip issue that caused mine and many other peoples' poco x3 phones to hard brick fixed or still present, waiting to detonate one day again?
and if i unlock bootloader to backup stuff, would it void warranty?

Unlocking the bootloader does not void the warranty.
For the rest, I do not know.

If they changed your motherboard you will have the same problem over time, the long-term solution is to have a rework "reballing" done, that is a permanent solution

Question Can anyone send me the output of their `dmesg`? My Poco X3 Pro seems to be broken and I wish to compare dmesgs to figure out what the issue is

Can you run `dmesg` on your Poco X3 Pro and share the output?
My Poco X3 Pro is no longer working and I'm trying to decide which errors displayed by `dmesg` are hardware errors, because most are likely to be just expected software warnings.
