Problem with WiFi, bluetooth and hotspot - Xiaomi Redmi Note 4 Questions & Answers

Hi guys, I got a big problem with my redmi note 4x qualcomm.
Yesterday randomly wifi, bluetooth and hotspot stopped working. I can activate them but no devices is recognized and my redmi is not recognized by others, so I guess they stopped working.
I reset the miui but nothing so I installed twrp and Pixel experience but still no response from wifi, etc.
Now I was about to follow this guide ° https://forum.xda-developers.com/re.../tutorial-fix-sensors-wifi-bluetooth-t3823622 ° but i don't know if it will work for the redmi note 4 because it's suited for note 5.
Can you please help me somehow?
Sorry for my english

If you did a complete factory reset including data and you still have the problem it's probably time to talk with Xiaomi as it could be hardware. Have you tried running some of the Apps that test and / or recognize hardware in the phone? Before this problem came up did you root or install TWRP?

I didn't root or installed twrp before the problem showed up, I guess it's an hardware problem. Thanks for the reply, all the "supernerdmasterdivinegenius-members" ignored me apparently.

Sensors stopped working - Help!

Hi everyone, I'm facing a severe issue with my Redmi Note 3 (Snapdragon variant).
Few days ago I noticed that the screen wasn't auto-rotating anymore, but I tought it was a temporary problem of my ROM (AICP official, latest nightly), so I passed by.
Yesterday I tried to format the phone from recovery and reinstall the ROM, without luck, the rotation wasn't working.
Then I tried to reset to the fastboot ROM (MIUI 7 6.3.17) through Mi Flash, I booted, and... now EVERY sensor has stopped working. Phone doesn't rotate, in cardboard app it doesn't move, brightness does not adjust automatically, screen doesn't turn off during call when putting the phone on the ear, and the compass is not working.
Also, apps like Lux say the value is -1 everytime, apps to re-calibrate the proximity sensor crash at startup, and I have a Settings force close when I enter security options to set up my fingerprint (only in CM13, from the MIUI7 setup I can register my fingerprint)...
So, I unlocked the bootloader then I tried to install MIUI8 but, IMEI was modified and WiFi wasn't working. I installed CM13 and restored NVRAM and everything (apart from the sensors) was working.
Now I re-flashed again with Mi Flash, and I can't SETUP the phone, because WiFi and cellular data are not working, and the phone is matched with my Mi account, and won't activate without login.
How can I fix all this mess? If needed, I can also take apart the phone.
Please, everyone, this is very urgent!
Thank you all in advance, and sorry if there are errors, as I'm writing this quickly.
HELL YEAH!
Ok, everyone, nevermind.
I FIXED IT!
It was the persist image that was corrupted. My bad I tought Mi Flash would reset everything, even persist. But I wasn't right.
I looked into the "flash_all.bat" script and "flash persist" wasn't there. Thanks Xiaomi for the headache.
2 days of searching on Google and I didn't find this thread, and I don't know how this is possible.
Now I just have to understand why this happened totally random.
Everyone that has this problem, refer to the thread up here, works like a charm!
Bye!
Thanks for sharing your solution. I learned something new.

RN3P Kenzo - Lot of random reboots and app crashes - possible a hardware problem

Hello!
I recently bought a Snapdragon Redmi (kenzo), it came with a chinese version of MIUI and on the first setup it already started to show some problems: when I try to connect to my google account it suddently rebooted. After some tries and reboots and worked but on day by day usage I continue to have random reboots and apps crashing.
I already updated to other miui versions, CM13, CM14 and some others roms and kernels, flashed with diferent TWRP versions, in all of them I got the same problem.
I think it's also not related to hard usage, because the problem appear when I open what's app, facebook, a lot of times with swiftkey. And I can open some heavy games without problems.
Also, sometimes it reboot and get stuck on a bootloop, when this happen, a backup restore or dirty flash wont solve the bootloop and I always need to go on TWRP, do a factory reset and flash the rom again.
I think the explain it's a hardware defect...
There are any other thing I can try to solve it?
Try flashing fastboot ROM if you didnt yet

I already tried once with miui, but I can try again with other ROM. Which one do you sugest?
You can only flash MIUI fastboot ROM via MiFlash, not possible to flash other...it must be a hw problem if you encounter that on every ROM...
Try flashing the developer ROM. Or look for similar issues on MiUi forum. Those guys will surely help you out!
Hit Thanks if I Helped You!

thanks pituca292,
i thing that would be no option for me,
i bought the device abroad, would be not economic for me to return it.
very strange what happening to my device.
reboots stopped (have no idea of what reason : recharge again from 5% battery, get into test mode (push 3 button for 10 sec': vol+, vol-, power).
but now other issue showed up : very lots of screen glitches, can use the phone like this, like some bad soldering inside.
first time i got into test mode, there were also screen glitches,
but now, whenever i get into test mode, downloading mode or the 3rd mode (with phone and cable picture), there is not glitchs at all,.
but after phone is starting - lots of screen glitches !!
i am lost

I'm stuck in Android 9 with my Redmi Note 4

Sorry for my english, but I need help. I have a Xiaomi Redmi Note 4 since May 2018 and since then i had the pixel experience mod on (the one with android oreo 8.1). Everything went good until yesterday my phone resets randomly and goes in bootloop with the google logo. So, i made a backup of my things and i did a factory reset with twrp, but apparently, wifi connection, bluetooth, sim card, volume and fingerprint scanner stopped working. I restored my backup but nothing changed, i even flashed a new mod, the newer pixel experience, the one with android 9, but i just messed up everything and now twrp doesn't work anymore as if i try to open it, it gives me the error "the device has been destroyed" or something like that. Even worse, my PCs won't read my phone anymore.
Summary: I'm stuck with Android 9 in the "welcome-fase" (?) because to begin use it i must connect to internet, and i can't do it in any way.
Sorry for my english. I hope someone could help me. Thanks.

Wifi and Sim recognition not working

Hi guys,
So I was using rev os with my poco f1 and suddenly it was rebooting on its own I didnt pay attention to that part and and slept away When i woke up it seemed that rev os was continuing to reboot itself so I decided to change the rom I noticed there was no wifi or cell connection to back up.Nevertheless, i went into twrp flashed the EVOx 3.0 and it didnt work flashed pixel experience beta 10.0 it didnt work even after flashed the stock miui of poco the wifi and cell connection didnt come back and now I am Stuck. Please help....
the Wifi switch stucks on turning on and then reverts back to off and there is no singnal for sim networks
Did you backup your EFS partition?
It contains important information regarding SIM, Bluetooth and Wi-Fi. Maybe your EFS data partition got corrupted. And the symptoms of a corrupted EFS are exactly what you described, No Wi-Fi no Cellular and Bluetooth. (also lags and reboot issues.)
Even if you flash stock ROM it will not restore EFS.
The other problem could be a loose antenna cable (Known to happen with POCO) even with people who haven't done rooting or flashing.
You have 3 options.
1: Flash backup up EFS partition.
2: Return phone to stock and give to service center.
3: Open the phone and check cables.
All the best.

Were they able to restore the IMEI for you?
I took mine to Mi service and before they even saw the mobile they said the motherboard had to be replaced, which I doubt. Everything from the camera to bluetooth, and sometimes even Wifi works perfectly fine. Only the IMEI has gone missing, not sure how though. I hadn't even rooted the device.

Redmi Note 4 Nikel infinite boot loop after turning on GPS

So I am having weird issues with this goddamn old phone. My intention was to root it and then work from there, I flashed this ROM. It worked fine for a while, but recently I tried to use the GPS and the phone simply started a reboot cycle that never ends. I wiped the cache, reboot it... and it didn't worked. And then a even more bizarre situation happened: I wiped everything (literally, only the SD card remained intact for flashing purposes), flashed this ROM, it booted, I selected the language, wi-fi, google account, create a PIN, etc.. the usual. But then 5 minutes later, the phone started the reboot cycle again, wtf? That's it, the phone is gone? If I am fast enough to turn on the "airplane mode", the phone stops rebooting, but as soon as I toggle it off, here it comes the damn rebooting again
I'm having the exact same issue on my Nikel. Today was my third wipe to get it working. I've read somewhere (can't find the source now) that it's allegedly related to a google play update that messes up some gps-related libraries and can cause bootloops on android 6 devices. For me it started on 24th February - I woke up to the phone already in the loop. Maybe blocking the update or manual removal can fix this issue. I'll try to find more info and will post if I figure something out.
Also, it wasn't flashed or even unlocked when it happened for the first 2 times.

That's so weird... I just bought a refurbished Redmi Note 8 Pro to substitute this cursed nikel, it's a damn shame how this version is not popular, meanwhile the snapdragon variant is receiving customized android 12 roms as we type these comments, nikel is abandoned smh I will try that "fix" you linked, related to the google services... see if that can fix the infinite reboot. I assume the google maps will not work? Who knows, these bugs are just annoying

And it didn't worked, the phone entered on a bootloop again, I had to quick turn the GPS off and that stopped rebooting. Such a weird bug... the curious thing about it is how the phone was working fine with the locked bootloader, the "original" MIUI, etc After rooting the phone, I tried the few custom roms we have here on XDA and I never used the GPS that much, so I didn't noticed the bug immediately. Tried to flash the MIUI again, the GPS problem remained. I was even willing to lock the bootloader again, attempted to flash MIUI through Miflash and it didn't worked. So I am stuck with a rooted phone (that is working pretty well, all things considered) but with no GPS
Right now the phone is working fine for me, so does the GPS. However, if google services ask me whether I want to increase navigation accuracy with google location service (I don't remember the exact popup text, I'm using a Polish version), and I click agree, everything goes to hell. I've been able to avoid agreeing to google location service until now, but it tries to trap me 3-4 times a day. I just know that it will pop up right under my thumb when I'm trying to tap something else, and it will be factory reset time all over again.
Hi I am in the same boat Note 4 nikel, when I turn on GPS, bootloop is happening.
Has anyone found a solution today?
So i find this link for Redmi Note 4 in
Firmware Redmi Note 4 MTK Untuk Yang Bootloop, Restart Terus Dan Bisa Buka Gps Akurasi Tinggi, Gojek Dan google Map
Download firmware redmi note 4 mtk miui 10, nikel atau 4x ini file khusus untuk hape yang bootlop bandel dan restart terus menerus
www.joelzr.com
I've installed it using spflashtool .. It worked for high accuracy navigation .. It only in english and chineese ..
Reuploaded the file in here ..

After a successfull flash .. Install the google installer apk .. And install your desired app .. And because google play took sooooo long to download app ( maybe my network signal ) .. I download the apk manualy from browser and install them ..
