Did you try to downgrade from Android 10 to 9, or how did it happen?
Do NOT flash persist.img, it contains DRM keys which will be lost forever if you flash another persist.img. Persist also contains calibration data of all phone sensors, which will get deleted as well (some can be probably restored with special procedure, but it's just unnecessary complication).

Baseband will fix after flasging fastboot rom it may imei too but in case imei not fix you need to restore efs from twrp(if you backup previously) or make new efs partition

You can try to restore imei and efs using my thread.

Try unofficial unlock bootloader bro vl work..u could request note 3 qcn file of note 3 users..I'm currently using z2 plus
Flash the right firmware for the device (if you don't know which one is the right, just keep trying until you find one that is working) and it will solve the problem (it solved mine without reinstalling ROM or anything just flash firmware, reboot and enjoy). If you flash any miui based ROM, you always have to flash the firmware otherwise this will happen again.
I have problems with IMEI and Mac (wifi). I fix this with QPST and clean flash.

Wifi mac address 02:00:00:00:00

Hi all,
Since 3 weeks I have this problem on my rn3pro sd version
I tryed to restore all backups I have with no luck.
I tried to flash china/global for miui 7/8/9 without success.
I think It's hardware failure. I tried ordered a brand new wifi antenna.
The imei is correct, the bt mac address it's already ok
Any tips for this?

Pretty weird are you able to connect to wifi mobile networks and Bluetooth device if yes then i would recommend to wait for the antenna to arrive although I think it's a hardware Issue and would require changing the logic board....
For this reason I'm suspecting the problem it's on wifi module

Once u turn on wifi the mac address would display correctly. Wrong mac address is displayed only when u reboot the phone nd wifi is set to off. But it wont affect the wifi functioning and the speed too.
As of now in LOS only issue persists is bluetooth MAC gets displayed incorrectly, but still BT works fine...
I can't activate the toggle

unlock bootloader and:

Redmi 5 plus MEG7 need modem files

I need these files please if somebody can share:
- modemst1 - modemst2 - fsg
Due to a kake ROM now I have corrupted my EFS partition and need those files to bring alive my device. Please help.
I have found MEE7 files in the web but I guess don't have to use on my phone.
Please, somebody with MEG7 can help me? I will be very glad to buy him a beer.
Hey there! I'm not currently at home now, but I can give you a direct link to NEGMIFA Rom(for Global Version phones), you can extract files you need by yourself.
Download_V9.5.11.0.NEGMIFA (as you can see, its an old version)
OR you can download_fastboot_ROM, and flash it with MiFlashTool, it should solve your problems.
Have a nice day.
P.S. If you cant download something by any reason, I'll make a mirror on googledrive or other filehost in an hour or two when I get at home.
I read somewhere that modemst1 and modemst2 contain IMEI so the rom doesn't have those files.
Fsg is also related to IMEI
Well, as far as I understand your phone not working at all, correct me if I wrong. So my algorithm to make it work is to flash it first(fastboot), doesnt matter with or without your IMEI(I think it'll be 0000), then you can search on xda or whatever, there was a bunch of threads with IMEI "problems", I'm sure you can find the right one.
Have a nice day.

Hi Dunaldo, thanks for your time.
Currently my phone is working on official miui 10 developer rom, it was bricked until I could open the bootloader and install twrp.
Now, the problems I have are:
1.- Baseband "UNKNOW"
2.- When I digit *#06# on the dialer: "UNABLE TO GET IMEI"
So I was reading a lot in the forums, and ,my conclusion is: I have corrupted the EFS partition or probably I lost it, then I need first to solve the "baseband" problem, for that I need the modemst1 - modemst2 - fsg files of my exactly device model and then I can get back mi unique IMEI.
By the way do you have the MEG7 model?
And thanks for your suggestion about flashing fastboot rom, I will try once more, don't think will resolve the efs problem but I'll try anyway.
I have the same problem & i have used the files ur looking for but everytime i restart the phone my baseband again becomes unknown ?? if u want i can give u the file link tomorrow but its no use
Search Qcn file in google for your model . restore it using QPST and write your imei thats all tested MEI7 works perfectly
Any solution?

You have an incomplete EFS partition, wifi mac is probably lost. You need to restore only EFS from an working backup. It happened to me once and this solves it.

If you don't have efs backup, I would suggest to flash stock rom with mi tool to completely restore the partition and pray that the wifi mac is back to its original address.
I had that problem the next day I updated to MIUI 11. It was really weird but it was just one day. I'm not really sure what I did but I think that I reset the networks settings and I rebooted the Poco before I added again my WiFi networks. Go to settings and search "Reset Wi-Fi, mobile & Bluetooth". Then tap on "Reset settings"
I am also facing this issue. I was on lineage 16 on a xiaomi mi 9t davinci then flashed MIUI 11 and couldn't connect to Wifi. Then flashed lineageos 17.1 and I still can't connect to wifi. Did you find a way to resolve this issue? Unfortunately I am not very experienced in falshing but any help would be greatly appreciated. Thanks in advance. I reset wifi- mobile and bluetooth setting but it did not help.

Question Persist 2101

Guy's, i need persist from 2101. Give me please. I have broken fingerprint, camera work perfectly. Try flash persist from 2103, EVERYTHING work excluding fingerprint. I think i can fix that, but i need persist from DN2101. Help please...
I have the same problem, OP does not want to provide the rom 100%. They offered me instead to send the phone in after-sales service.
persist img is uniqe if not backed-up you're screwed. you cant use someone elses persist back-up.
try contact OP aftersales in most cases when unlocked bootloader you still have warranty at oneplus

Man, i don't know, but persist flash via command "fastboot flash persist persist_image.emmc.win". Or persist.img, of you want rename it.
when you backup you can clearly distinguish between persist.img(sda16) and persist_image.emmc.win. I find that strange. Both have basically the same content, different weights, with a slightly different structure.
