OPO experience bootloop every time it heats up, does good job when it is cool

HI,
My OPO 64GB sandstone Black is experiencing Bootloop everytime it heats up, then i turn it off for 5 minutes to make it cool. After that, it works fine. I bought it about 8 months ago. A month ago, I upgraded it to CM13 official. About 15 days ago, it suddenly went bootloop. Then i checked and found that it was softbricked. Then I did some homework and unlocked the bootloader and downgrade it to Kitkat CM11, but lost all of my data. Finally it came back to life, but the bootloop comes everytime it heats up till now.
I have some question and also asking for a solution to overcome this problem. Questions are listed below
1. What is the suitable solution for this problem?
2. Does my device have any hardware issue or is it just software related problem?
3. Will my device work like before, if i somehow find a solution or its the type of problem which keeps coming back?
Please help me regarding this issue. Thanks in advance.

Hi, have you tried to undervolting the cpu? This might help you to keep it cold
You only have to flash a kernel which let you customize volting values
And If the problem persist try to clean flash the latest oxygen os (It has the latest drivers so maybe it works).

Try this: Install Kernel Adiutor, underclock cpu to 1728 Mhz, Undervolt (if possible) by -50 global, and enable everything in Thermal

I have the same issue. Is there any solution?

Did u even try to downgrade to miui 11?
Hmm i blindly believe u...and now I lost fingerprint options. and I didn't create backup of persist.img
Hope other sensors are fine. Please in future don't answer anyone with guess and if u are not sure.
EDIT: Tried everything to back fingerprint on miui 11 but fails. All other sensor is fine even L1 widevine is ok. After flashing MIUI 12 fingerprint is back but i think it working slower (maybe placebo effect)

Hey,
When i had a trouble, or stutter on my fingerprint on my oneplus 3, to avoid that, the tips is to delete all fingerprint, and restart saving new one. Try it and tells me if it works.

I did the same thing without any FOD problem (V12.0.3.0.QJKMIXM to V11.0.2.0.QJKMIXM miflash).
But i lost fingerprint with a Weekly EU rom.
I solved the problem with this method:Flashed with miflash V12.0.3.0.QJKMIXM clean all and lock then :Go to the CIT menu press the 3 dot in the top right of screen scroll down calibrate the FOD -> place a white thing on FOD click start before next step put something black on FOD and press next...wait until finish close restart and add your fingerprint(Thanks to tze_vitamin).that's all...

i was downgrade 12.0.3.0eu to 11.0.6.0eu (clean all and lock method) and lost FOD. Tried everything to back FOD and only solution for me was flashing back 12.0.3.0. Didn't try with calibration on CIT as i didn't know for that..all i was tried in CIT was fingerprint test which failed. Thanks

yes i was using miflash to downgrade and i was downgrading from 12.0.3.0 to 11.0.6.0 and i was lost fingerprint, since 11.0.6.0 is last and only MIUI 11 for EU i was not able to flash any other 11. so i was back on MIUI 12 again to fix fingerprint problem.
Right now im using 12.0.4.0 Indonesian rom with locked bootloader and im pretty happy with it, im only missing miui launcher right now.

Problems with my Xiaomi Redmi 8A

Hello people of XDA Forum,
Since a couple of years I own a Xiaomi Redmi 8A, which I ordered brand new on AliExpress.
After a couple of failed attempts to install a Custom Rom on the device, I still have an unlocked bootloader
and a "offical" stock firmware on the smartphone installed. Sadly now occurs an other problem,
frequently the screen "freezes" when I want to use the touchscreen. Sometimes when I put the power-button
and pressing it another time the screen responsed to it. But not always, it's getting very frustating when
for example I play "Call of Duty Mobile". My question is that I want to know of the problem is software-
or hardware based? Hopefully you can help me out, thnx

Have you modified anything in your device recently? No? Then it's probably hardware issue.
Do you have any damage to your phone? Then it's even more likely to be hardware issue.

Thanks for the reply. Now I have this problem for a couple of weeks sadly... There is no visible damage on the
device, but I have dropped the smartphone a couple of times out my hand... So I have this problem and I thought
that a firmware upgrade might help me out, but the problem still remains.

If you think the damage to your phone is significant enough for it to affect your screen then maybe you should send it for a checkup.
Although you can try using different ROM to test if it works since it's probably much cheaper to do so than fixing the screen.
But don't flash an OTA update, flash latest stock ROM manually or flash a custom ROM. That way the settings are reset, you can backup your data with TWRP.

Allright, thank you very much for the suggestion. Finally I managed to flash an older Fastboot ROM through
the "MI Flash Tool", which solved my touchscreen problems.

POCO X3 NFC stuck on MIUI 12.0.8.0 Android 10, can't seem to update

Hi, wondered if someone could help. I have just got my phone back from the repair shop and it has been factory reset, which is fine, but it has now got an out of date OS etc on.
I've tried downloading all sorts of ROMS from the xiaomifirmwareupdate page, and it just keeps failing whichever I choose. Wondered if one of you clever souls can help?
Many thanks!

Try to flash the latest MIUI via MiFlash-Tool...
My wife had the same problem => now latest MIUI is running on her phone.

Hi thanks I run the tool yesterday but it told me I have to wait 128 hours

Hello,
Same problem here.
I updated my X3 NFC EEA as soon as updates went out, so I'm on latest (12.5.4 R).
My wife didn't update and now she's stuck on 12.0.8.0Q.
I understand I could update with Mi Flash Tool, but doesn't it require to unlock device for fastboot (and then need to wipe) ?

tbh, you're all not stuck with 12.0.8.0. eventually you'll get the update. because not all phone/device got the update at the same time. some device got the update and some others not yet, i think you just need to wait

I hope you're right, as Xiaomi doesn't roll out updates for everyone at same time, but 12.0.8.0Q is pretty old (february).

You mean the bootloader-unlock-tool, right?

I did. I tried it again just now, it says wait 96 hours grrrr

best bet is to keep trying the updater every few hours . im on the latest version now and not once was i notified of an update , just kept checking . also try clearing the updaters cache / data , i remember that tip from my note 5 days lol

I confirm. My device is Poco X3 Indian (Non-NFC. Karna codename). Software stuck v12.0.10.0 and last update time is April. I cant flash any roms. I must wait unlock the bootloader.

Qualcomm Crashdump happening almost every day

Hi !
Some time ago, I switched to crDroid (because I don't like OOS12) and I started having some Crashdump (no error code) every day or two. If I force shutdown and restart, it works well for a time but crashes at some point.
At first I was thinking it was crDroid's fault so I went on DerpFest but the same is happening.
I've seen some posts where people's phone are bricked, which isn't my case.
Before installing the roms, I used MSMTools (MSMDownloaderTool-20210201-kebab) to reformat the phone and flash from the cleanest state possible. I have the KB2003.
Does anyone knows how I can fix it ? It happens really randomly (usually when the phone is locked, but it can happen also when using it) and I really don't want to come back to OOS...
Thanks a lot !

If this happens on all ROMs it may indicate a hardware problem e.g. with memory or smth else.
If on other Roms it works without issues. Flash stock OOS11 with another MSM (that you did before) and try installing CrDroid again.

I used the EU version, you mean trying something like International or just the EU from another website ?
Also, it seems to happen when I receive a notification from FB Messenger. Not on every notification but every time it happens, it seems to be this.

Yes, try International and India Roms.

So I tried the international one a week ago, it was fine for a few days but then the crashdumps came back.
I'll try getting back to OOS and see if it happens again, in that case I'll send it for repairs maybe.
If it doesn't crash, I'll be real sad that I'll need to use OOS...

Update after a month: OOS doesn't crash at all so maybe I'm doing something wrong when installing custom roms (don't know what as I tried 3 roms with differents methods)
