WiFi and Bluetooth don't work after following the unbrick guide

Got my OP3 hard-bricked recently. I followed Naman Bhalla's unbrick guide and flashed down to OOS 3.x. Everything works fine except the WiFi, Bluetooth, and GPS.
The GPS toggle activates when I click on the icon, but it never calibrates my actual position.
The WiFi toggle doesn't activate, no matter how much I try.
The same goes for the Bluetooth option as well.
You can see the problem for yourself here
If I try to flash a new version of OOS, the phone freezes mid-boot and keeps restarting.
Any suggestions?

What happens when you try to activate these from Settings?
Flashing OOS later versions may solve the issues. What method did you use for flashing the later versions, adb or TWRP? Try adb.
I didn't face any such issues when I used the Unbrick Guide.

@rahulkulhalli
Do you have op3 or op3t ? This is for op3 .
If you have op3t use this guide

I tried, but I run into the same bootloop.
I used TWRP touch.
Could you tell me what steps you took after flashing to OOS 3.x?

I simply flashed the then latest version of TWRP and then clean flashed the later version of OOS and then clean flashed custom ROM coupled with flashing of proper firmware after a couple of days, all using TWRP.
Which version of TWRP do you use? After the OOS 3.x boots up, flash TWRP 3.2.3 official and then try using that for the further ROM installations. If this also fails, use adb to install the ROM. Don't go straight to a custom ROM since you seem to have firmware issues.
You haven't said what happens if you try to enable wifi, BT etc from Settings instead of from Quick Setting tiles.

What I think is you need flash the latest wifi and bluetooth drivers. Just download them from this link and flash using twrp

You may need to reflash the OS after installing the firmware. Don't directly try to install custom roms after flashing the firmware. First flash latest stable build from official oneplus site, boot into OS and then you can do whatever you want with your device.

should I flash recent fastboot rom?

hi,
I need advice again practically on the old matter. so since I bought my device I had always had wifi dcs. Most days I need to restart my phone 1-2 a day. I tried many things but it just doesn't get fixed. so I want to try something new. in may / june 2018 I got that phone which was on miui 9, I flashed twrp and some aosp roms. never gone back to miui, I always had arb3. last month I switched to arb4 oreo and immediately to pie firmware. but still nothing changed. now for a long time I noticed, if I flash any aosp rom I get the message like "target device 9.5.x.x". so while flashing my device show my old miui 9 version as target, never bothered by this. but now I wonder, what if I flash a recent fastboot rom with miflash to completely reset my phone. then reinstall twrp and any aosp rom again. do you guys thing that might change anything? well besides the number on "target device". right now I have most recent beta global firmware, can I flash recent stable global fastboot rom? (not sure about that arb4 thing, does it count as rollback?).
thanks in advance

Well who is interested, I did what I wrote and stayed on miui 10 for now. I had 2 days in a row no wifi dc. I test some more and then return to aosp and test there.

It's always safe to flash any room which has same antirollback version (arb4 in your case)
You can flash 9.5.19 stable Oreo ROM to 10.3.1 android pie fastboot ROM without any problem..

4 days now and still no more wifi dc, should have did that way sooner. will try aosip pie next.

Do I need to downgrade pie firmwre if I were to use oreo android ?

My whyred RN5pro come with global rom miui 10 with android pie I think ?
I unlocked the bootloader and flash PE pie latest version, it required pie firmware, and I flash latest pie firmware from https://xiaomifirmwareupdater.com/firmware/whyred/
After usage for half year, I decided to use oreo rom, there's a few reason.
1. I thought always keep update will make it more stable and safe. But I was wrong, the more I update the PE rom, the more unstable it was. After usage a few days, it will freeze and need reboots, sometimes it slow on animation.
2. I need call recorder, but android pie restrict this function.
3. The latest build now come with wifi drop or something, sometimes my internet access is unavailable while my wifi was working fine.
After that I think a lot whether to use pie or oreo, and which custom rom suits my need ?
After reading and searching, and thinking a lot in these 3 days, I come up with a solution.
1. Because the pie keep get updating, it always got bug and some glitches stuff, and I don't have a lot of time and don't like to keep flashing new custom rom, I decided to use Oreo Custom rom final version instead.
2. After a lot of research I come upon RR, PE, havoc OS, liquid remix, lineageos, and decided on lineageos 15.1 final version as my custom rom.
3. Because I don't need a lot customisation, I think lineage os is the best for me, as I only need privacy guard, network traffic indicator, and stability.
So I changed to lineageos 15.1, here is what I do
1. wipe dalvick cache, data , internal storage
2. flash oreo latest firmware V10.3.1.0.OEIMIXM from xiaomi updater site
3. flash lineage-15.1-20180709-UNOFFICIAL-whyred.zip
4. flash magisk 19.3
5. flash opengapps pico
6. flash lazyflasher no verify opt ( ended up failed / error ) Because I read some user getting bootloop caused by encrypted phone or something, I don't know about this part, so I just flash lazyflasher as the instructions said for uncencrypted phone ( ended up failed / error ) ( I don't know if my phone encrypted or not, so I just flash it as additional file)
7. reboot, after getting in, it shows android encrypting, and reboot again, after a few minutes, I thought it stuck on boot loop, but finally it gets into the welcome screen. I tried reboot a few times to see if it stuck or not, but it was working fine. Tested the rom 24 hours by now, and everything seems to work fine.
What I want to ask is,
1. Does my step on changing from pie custom rom to oreo custom rom correct ?
2. lineage-15.1-20180709-UNOFFICIAL-whyred.zip Is this the final version of oreo lineageos 15.1 whyred custom rom ?
3. Sometimes I saw my sim network bar gone completely, but I can make call and check balance, and in the sim status, it show -100dbm and 99 asu. Is this normal ? Or is it because I flash wrong firmware or something ? Or is it caused by my area unstable tower network so the bar completely gone ?
4. Should I use pie or oreo firmware in this custom rom lineageos 15.1 android 8.1 ? Or it's irrelevant because the firmware is flashed by the lineageos custom rom ?
5. Do I need custom kernel ? And what's the best custom kernel for android oreo ?
Other than that, I am satisfied with everything it offers. Thanks for reading and replying.

1. Yes. I've never flashed lazyflasher though.
2. Yes.
3. If you can call, it's probably just very weak signal and the indicator goes off. Otherwise it's a bug in LOS, I doubt the firmware has anything to do with it (I'm on Oreo too).
4. Oreo.
5. No, but it wont hurt you if you try a couple - just make sure they work in Oreo firmware. I'm on KangarooX R4.4 and getting over 10 hours of SOT.

(Solved) WiFi and camera not working after flashing global ROM on Redmi Note 9 Pro 5G China

I am asking this question for a friend.
He has a Redmi Note 9 Pro 5G China, and he had the China ROM on the phone (V12.0.11.0.QJSCNXM).
A few days ago, he installed the Mi 10T Lite Global ROM (V12.0.2.0.RJSMIXM) on the phone with Mi Flash.
After booting to the global ROM, WiFi stopped working, the WiFi switch is on, but no WiFi can be found by the phone.
Camera also does not work.
So I think this means the persist partition is corrupted.
We have tried to flash persist.img to the phone in TWRP with Terminal commands, but that did not work.
We have also tried to flash persist.img to persist partition directly using orange fox recovery, but after doing that WiFi still does not work.
We have also tried to re-flash the global ROM using Mi Flash, and to flash directly using flash_all.bat, the result was still the same.
If anyone knows how to fix corrupted persist partition on this phone, please let me know.
Thanks.
Edit: It was solved by installing the China ROM back on the phone.

I have 9 Pro 5G here and I tried to install a Global ROM, but I also had the same problems. What happens is that it seems to me that despite sharing the same platform, the Mi10T Lite and the 9 Pro 5G have some peculiarities, such as the camera which is different. So, I went back to the Chinese ROM and installed xiaomi.eu. At first, I'm looking for the XQCN file of a Mi10T Lite to test here on the 9 Pro 5G.

In my case, it only resolved by switching to the Chinese ROM. But then I took advantage and went to xiaomi.eu, I am a big fan of their ROMs.

@Hemerson Silva Thank you!
Now WiFi and camera are finally working after installing the China weekly ROM.

Hi,
Does everything work after installing Xiaomi.EU ROM, camera and WIFI all okay?

I also have Chinese Rom on my RN9 pro 5G, after update to 12.5 Chinese finally kill Google services. there is no way to install it anymore, is anyone try to flash EU rom for this device?
or the best way is to flash Xiaomi.eu custom rom?

is like redmi note 9 pro 5g and the MI10T lite are using different wifi chip. anyone using global rom in the redmi note 9 pro 5g model M2007J17C and solve the wifi issue? please can share the rom using. or a way to make it work.

I found this through Google and had a similar problem with my Redmi Note 5 and custom ROMs. The problem with no device drivers is when the "Vendor" partition was not flashed or restored. It is very important to back up that partition as well. Alternatively, the Vendor image can be found in the fastboot ROMs from Xiaomi, extracted and then flashed separately in the recovery (very fiddly, but it's an alternative).

What's the process for extracting the vendor image and flashing it? Before MIFlash I mean, because I'm facing a similar issue with my Redmi Note 10.

Question [HELP] POCO F3 EU OTA updates / even manually Updates don't work

Hey all
I recived the miui 12.5 enchanced [ALIOTHEEAGlobal_V12.5.3.0.RKHEUXM] (2.9 GB & 466 MB) Update a few days ago via ota. My rom is stock - no root or custom Recovery. The download and installing process work fine, but then the Phone need to restart. While restarting the Phone stuck at poco Logo. Only with a few reboots (or leave it alone for a long time) the Phone comes alive again. Then there is the Info miui update failed after reboot. I also tried to Update manually the Full and increment Rom over the three dots menue. No Chance. Even if i install my current rom version [ALIOTHEEAGlobal_V12.5.3.0.RKHEUXM] again - the same problem
I searched the whole Internet and couldn't find someone with the same problem.
Please help.. Thank yo all!
FYI: I cannot do a full reset / wipe with data loss, because i have so much banking apps and accounts. I need a full day of restoring my current status and i don't have the time at the moment.

No one?

Hmm... I don't know if it possible with locked BL but try boot from B partitions? Are they for cases like this one, aren't they?

I dont know this option. How will this work?
I backed up my phone as good as possible und tried to flash with "XiaoMitTool V2" my currend rom and the 12.5.6.0 and it always endet in "miui sideload failed". WTF is here going wrong .. While sideloading it stops at 4.99% on phone screen.

Have you tried with 12.5.6 via stock recovery? (full rom ofc, not OTA). It doesn't erase your data.
I also tried ToolV2 with my F3 and no luck too.

isnt 12.5.6 eea enchanced? 12.5.3 is older update in eu

I tried to update through stock recovery and MIAssistant but no success. Like @crysus said, it stops to 4,99 on phone screen, no error but it boots to the old ROM. Maybe because is a stable beta version.

Mine updade went all good without hassles. I updated it via stock recovery but first I use 3 dots menu in system updater app just to show where update file is. (full recovery fw used, not just OTA).

The fastboot version of 12.5.6_EEA has been available for a few days now, it can be Flash with miflash.
