GOOD DAY NEED HELP PLEASE - Redmi Note 9 Questions & Answers

Good Day and Peace and Blessings to everyone here.
My problem is that my daughter's phone (Redmi Note 9) has been giving trouble with recognising the dual sim and memory card tray, this happened some time after purchase and it's first update to MIUI 12. Normally this would happen when the phone was restarted, the tray would have to be popped out and re-inserted and then the tray would become functional.
Recently when it updated to MIUI Version 13.0.2.0 Global Stable (SJOMIXM) it has completely stopped recognising the Sim and memory card Tray, you could see it appear and disappear as if trying to work before there's n error message about the .com.phone something not functioning and then it would shutdown and restart in the recovery mode.
Nothing seems to fix this issue so I'm stuck with a phone that I cannot use, I would like to know if there's a way to troubleshoot this issue or if there's a way to install another rom for this phone to function.
I'm familiar with troubleshooting phones but this one has been challenging me for some time now. I've read that there has been an issue with the sims not being recognised and that this new update was supposed to fix it, unfortunately it hasn't.
So far the best I can tell or think is that some of the firmware was corrupted, so I'm wondering if there's a way to completely wipe the phone and reinstall all software to somehow get rid of the problem.
Any assistance would be greatly appreciated

Make sure the bootloader is unlocked and USB debugging enabled. Download the Mi Flash tool and an older MIUI from Xiaomi's website or from https://xiaomifirmwareupdater.com/archive/miui/merlin/. I'm not an expert in firmware and ROMs. I just flashed my RN9 with a well-maintained ROM and just never looked back at MIUI. Also, try testing out the earpiece and the proximity sensor if the screen turns off once you cover the top. It could be that the IMEI numbers got lost. Try opening the dialer and enter *#06#, you should see a popup showing your S/N and IMEI numbers.

Flashed kdz with lg software, imei and boot problems.. Help please

. I flashed the KZ file with lg update software as explained in the XDA thread but I could not get the process to work right. My phone kept disconnecting at 28% and it would not turn on no matter what I did. It would only make a short vibrate as if it was turning on, and the computer would notice it but only for a short time. And never once did a light on the screen, or LG logo, or anything at all ever appear.
I figured I had really screwed it up, but when I plugged it into the wall it booted up perfectly. All my data was in tact and the rom i had flashed through cwm was still there, not the kdz file that I flashed with the lg software.. I noticed that my sim card did not come up as being in the phone at all. I looked in system setting status and noticed that all info related to my imei said unknown. I opened up the mfg app (277634#*# from the phone app).. Under "version info" then "factory version" my phone now says xmm6260.. It always used to say p925..etc... Even after flashing the zip to debrand from at&t this never changed from p925 even when every other aspect of my phone has.. I was hoping maybe once I put in an activated sim card everything would be fine and my phone would be unlocked which is why i flashed through lg software.. But seeing as how other people are having this similar issue and their phones not seeing the sim card, well im looking for some advice.. Should I try and re flash kdz file through lg software again? if i do, im going to do it on my XP computer this time, not Windows 7..
Just wanted to add that I did try wiping data and cache from cm and no dice.. Root and CMW work fine but no matter what I do, if my phone is turned off, i cannot boot up or boot to cwm or boot at all unless i plug the phone into a wall carger and then once its on it stays on and i can unlug.. SORRY ABOUT THE LONG POST, THANKS IN ADVANCE FOR ANY HELP..
I would reflash CWR first and foremost, then try to flash back to stock.
No IMEI/GSM Radio
Hi, were you able to fix your problem? If so, could you please give me a hand, I have same problem.
Im attaching a couple of screen shots, one where you can see that IMEI is not shown and other is where you see the phone number thats on the SIM but has a sign like if no SIM were inserted.
Using the KDZ detects the IMEI, but after flashing it doesnt show up on phone.
Thanks
Took my phone to a cellphone shop and they fixed it. Everything is back to stock and working normal.
Hi ive got the same problem, did you fix it?
Yes, my phone is working perfect at stock. Im going to wait for GB ir ICS with a working 850MHz baseband.

[Q] Various Issues - Tried different ROMs but issues remain

Hi guys,
this is gonna be a long story, but I'm at end of my wits.
So my phone (HTC One M7_UL Vodafone DE) got water damaged (it was submerged in water for at least a minute). I tested it again last weekend and it seemed to work in terms of hardware. I managed to test the speakers, the charge jack, the headphones jack, wifi, gsm, both cameras, etc. it all seems to work fine, and it's not about that anyways. I kept getting a "com.htc.htcdialer" issue, saying the process had unexpectedly crashed and then a few minutes later the phone would reboot. I tried finding out what this error was and how to fix it but I couldnt find anything. Also its weird that I got a software error.
So I unlocked the bootloader (via htcdev.com), flashed the latest recovery (I tried both cwm and twrp), which was also fine. I managed to install the latest Android Revolutions HD (53.0) and thats where the problems started again: I would get to the lock screen but as soon as I would swipe up to unlock it I would the white screen with the HTC letters on it. I tried wiiping all the cache and partitions i could find and reinstalled that rom, but the problem remained the same. Tried a different recovery (twrp) repeated all the steps and still no more luck than before.
So I decided to give a different rom a try and just flashed the latest stable cyanogenmod rom on it, and that boots fine, but eventually without error message reboots as well.
Then I tried flashing the latest viper rom, but there I have the same issue as at the beginning, that I get as far as the lock screen and then it just wont let me unlock it.
And that's where Im at the end of my wits. I cant imagine its a hardware related issue, but i might be wrong.
Ideally I would love to get my hands on a nandroid backup to restore the phone to stock, a stock rom ruu, but I cant find any of those either.
I'd really appreciate your help.
Let me know if you need specific details of installations, versions, decide numbers, etc

Phone doesn't read my SIM

I have been using CM11 (14-03-2014 I believe), without major problems until yesterday. Sometimes my phone seemed to disconnect from my SIM and I had to re-enter my pin code to reconnect to my operators network. But as of yesterday my device doesn't seem to recognize the SIM card, It doesn't ask for a code at all and can't make any connection whatsoever. I didn't change a thing, this problem started out of the blue.
I wiped cache and dalvik, updated to the latest CM nightly (08-05) but that didn't make any difference. In other threads I read about the baseband that might need an update, but I can't check which version I have now because when I try to enter the hidden menu I get the no network connection error. The strange thing is that CM11 has worked with (I guess) the stock baseband.
Is my phone tripping or could it be that my SIM card is broken?
Help and thoughts will be very much appreciated
Try it on stock to be sure about it.
After some searching I found a phone that could fit a regular SIM card, a Blackberry 9900. My SIM worked perfect in this phone, so that is not the problem.
I Also did a complete wipe and installed a stable version of CM 10.1.3, but that didn't seem to help. I hoped that a downgrade would have done the trick. I might try a ICS ROM or the stock firmware, but I kind of lost hope and i'm starting to think this problem is hardware related in stead of software. I'll report back with results on stock firmware and the ICS ROM.
How can I make sure the SIM reader in my phone is working properly?
Sorry for double posting, but I got an update:
SIM wasn't working with ICS so I decided to go back to the stock ROM. However, when I tried to flash V20B.kdz with KDZ_FW_UPD, the program got stuck at wParam=2010 and iParam=210. The phone is now stuck in S/W Update mode, and I haven't found a way to restore it yet. I will argue a little more with my phone when I get back from work, I'll open a new thread on how to unbrick when I can't do it myself.

I have the same problem, and exactly the same error at reflash.
Dead end. Buy a new phone .
I tried to flash it about 80 times. One guy from a gsm repair has a bit luck and make it work at the first, but then, when he wanted to repair my imei, the phone stucked again in S/W Upgrade.

[Q] Random freeze rebooting Xiaomi Mi5 problem!

I bought new Mi5 and I still didn't put Sim card inside wanted to configure and see what phone can but when I entered configuration menu after 1st power up I manage to choose language and few things more and phone rebooted, then I manage to almost finish configuration then freeze and reboot again, after few tries I finished configuration but freeze (usually only last few seconds) and reboot happen again. Then phone offered me update software which I manage to reach from 3rd time and successfully update only with Mi PC Suite, not from phone update app. Interesting, all flashing proces with Mi PC Suite always is going as should be, without reboots etc... Crap happen only in OS. Now I got latest China stable (I bought phone in China) which has same problem with rebooting. Then I wiped all I can, factory reset etc...nothing helps.
-Still didn't unlock phone in case I need to return it.
-Didn't try global Rom because I can't flash it
I was reading forums and found a lot people have same problem but didn't find what they done on the end to make phone work.
If anyone have some solution, let me know. Returning phone from EU to China is not 1 day Or does someone know if someone in EU can service this if needed?
thanks in advance
huh,
I solved (for now) problem with installing this, developer version of miui 8 from here
http://xiaomiadvices.com/download-miui-8-6616-china-developer-rom-recoveryfastboot/
Downloaded it and installed with English version of MI PC Suite. Developer rom is Chinese (as my default software version in phone) over latest Chinese 7.3.10 miui
With original software phone was restarting, freezing randomly every 30 seconds or 1 minute of usage.
Now need to wait to unlock phone so I can use Global version of rom to get play store etc...

Mi3 No SIM card issue

Hello, I was using lineage Os latest nightly when I encountered this issue. I wanted d2w. So I flashed Zurion X. Phone rebooted to TWRP. So I flashed recankut kernel. Phone worked. But I noticed that it started showing no sim card. I tried flashing Lineage Os back and nothing. So I flashed MIUI latest global beta via fast boot. No SIM card issue persists.. Now Im beginning to think that the issue is hardware issue.. I dissembled the phone.. But the sim card connectors seems to be OK for naked eye.. MY phones I will is not affected, neither the baseband.. So I'm out of options now. Can someone suggest me a workaround to bring my phone back to life.
Thanks.
Also it seems that I can make emergency calls.. Which means the radio I working

It was my sim card tray.. The lower right coner of the sim tray was broken and it interfered with the sim card identification mechanism. With a new simple card tray my phone is fixed.
If the SIM card tray is damaged (for example, a piece of plastic is chipped off or a metal plate is deformed), this can be the cause of the problem when the Xiaomi smartphone does not see the SIM card.
I had such a situation on my Mi 3. In the service center they could not find the cause of the problem, I found it myself.
I hope this information will help to somebody.
