You can put it backI did it the same day. Then he washed it with alcohol, but did not put the lid back. Still works like new.
But remember don't press it
Capacitor is big
Has anyone succeeded in repairing a bricked Poco M3?

Hello. I'm new to this post but I'll share my experience with the blank screen of death Poco M3. I've NEVER updated it for this same reason of becoming bricked. However, after using the phone for 6 months, I began to notice the phone got hot without me doing anything so I rebooted it, big mistake lol. It didn't come back on, apparently until the battery was fully drained! After going through this 5 times, I was still under warranty and wanted a new phone to be honest but the repairman actually fixed it. He removed a very small five sided metal enclosure on the chipboard which he said was preventing the current to power on the phone. No problems since, it works like normal. my contact info is on bit.ly/3tqhbhk
Thanks for the report.
Seems your repairman reads also the xda forums and found the fix here:
poco m3 does not turn on anymore
I recently updated my Poco M3, it updated correctly but after that, it doesn't turn on anymore, I searched about it and I found that it was a problem with the update. I managed to turn on my phone again by pressing 13 seconds the power button...

My phone's battery got zero and it didn't turn on again. Same problem.
Now I have used the heating IC method. No success. What should I do?

You may remove the shield that is shorting a cap. Take a look here:

Hello everyone, initially sorry for my English I use Google
My case: after an MIUI update it was blocked, the symptoms: it did not turn on, it did not enter Recovery, it did not enter Fastboot, nor did it load
What I did initially: search all the possible methods by Google and none worked, only disconnecting the battery worked so that at least it would charge; then I found the solution to let the battery drain completely and put it back to charge until 100% turned on but it was still stuck on an infinite reboot. I gave up the 7-month 4Gb / 128Gb equipment for lost, I tried to contact the warranty without any response ... Note: never use temperature methods to the chips, or to the board, or bridges, anything electronic.
If you recognize by usb on the pc, the driver: "Qualcomm HS-USB QDLoader 9008" then this you should do:
The solution:
1- Simply disconnect the battery and the flex from the screen then reconnect them.
2- Now leave it like this for 8 days until the battery is completely drained (you should not do anything else, it will discharge itself)
3- After 8 days connect it to the original charger and let it charge for 5 minutes, without disconnecting the charger, click the power button and it should turn on normally as if nothing had happened; I know it seems like something funny or stupid, but that method worked for me, maybe it was luck, I don't know, I had been battling a solution for 3 months, I just wanted to eagerly share this solution before they damage their cell phones by doing experiments with their motherboards. I wish you luck.
Note 2: the phone was only uncovered to release the battery and screen flex, nothing more for that ok

I don't know what IC you mean. For me it was enough just to remove the shield.
Maybe take a photo and send it to sarabbfrani's whatsapp.
Take a look if the phone is still in EDL, if you connect the usb.
That isn't a fix, only a workarround in order to power on the phone.
Culprit is a shorting, inside the phone, which needs to be fixed, or the deadboot can happen anytime soon again.
I did. The problem seems to be in the capacitor at the charging cip. But before anything else, you should first try to disconnect the battery for a few minutes, then connect it back. If that didn't help you need to open and take the board out. Open and exposed the charger cip. Then by using a hot air gun, heat that area until the soldering melt. Do it carefully because if any of the components move, your screwed. Let it cool, and re assembly everything. Cross your fingers and push the power button for 2 minutes. If you did it correctly, it should work
No, it wont (if your phone is already having deadboot issue)
Yes, if you never had issue before, it suppose to work normally.
heyyy can u help me with my device?Guys this is my procedure to turn on the phone:
I can make it turn on Android after messing with the battery and sub-board cables but this is just a workahound, trying to turn it on normally through the power button always makes it turn on in edl mode
But opening the device voids the warranty, so anyone who has access to a repair center is better off asking for the warranty
What to do:
1. Disconnect the battery cable and the secondary board cable.
2. Connect charger.
3. Hold the power button.
4. Connect the secondary board cable and quickly connect the battery cable.
5. Release the power button when the device vibrates.
It doesn't always work the first time, you may need several tries to get it

no pmic also motherboard is healthy do not attack your MB.)
i will post the fix just wait3I just wait till the battery totally discharge and then plug in the charger,sofar been through this problem for 2x,the first one for 2 days and 5 days for later because the battery was full.
This happens when Im restarting the device and now even there is a new update,Im still scare to update my device to the latest firmware incase it wont boot again.
Should I try to update or nah,guys?3
This problem started to happen to me while I was running Crdroid. A couple of weeks earlier when it was still in the stock ROM I had installed update 12.0.8. Install custom ROM does not solve the problem. Although it appears to be an issue created by an update, it's not simply a software issue, it's a problem that was bound to happen. If that weren't so, Poco's repair centers would only be repairing the system of the devices that arrive there and not entirely replacing the main board. I also have a suspicion that this issue is happening with a specific manufacturing batch. Mine and those of people I know with the same problem were manufactured in 2020.11. I would like everyone here with this problem to say the date of manufacture of your M3, you can read this information on the box.
