Check if your phone still knows IMEIs
Maybe check this thread:

I loos my imei. How i can restore? I have unlocked bootloader..

OMG, this XDA app. When I want to post, it sometimes fails and pops-up totally useless "Broke the matrix... Neo..." and on next attempt it posts my message in double
Edit
Actually, you also posted the same twice, opening another thread for the same:

Xiaomi Redmi 2 2014811 Best Rom?

I am currently on MIUI 7, the one just before it updates to MIUI 8. What I want to know is, what is the best possible custom rom I can flash to that will work with this device? I have Team Win Recovery 3.0.0.0 installed.
I have installed Redmi 2 2014811 for my casual user (no root or else) with this base rom : miui_HM2XWCProGlobal_V8.0.7.0.LHJMIDG_3240991baf_5.1.zip via CWM

Cool thanks, I will look up the rom. I thought about Android 6 or 7, but see those still have some major issues here and there.

Major issues?which ROM r u talking about?there are so many ROMs those are pretty stable.Only minor bugs(miui also have this)
BTW devs work very hard for these ROMs and they got nothing but our thanks and encouragement. These custom ROMs are way better in performance and customization than sluggish and heavy MIUI rom.
My phone is 8months old and this phone is still with me because of efforts of devs.
So don't be so demanding about 200% no bug and be thankful to them.

Don't get me wrong, I am very grateful. I worked on Windows Mobile roms back in the day so know what type of work goes into it. I have only started to look at custom roms today and am so completely lost, guess I chose the wrong word being major. When i said major I had camera and Gps in mind, as I saw some of those roms had issues with those. So again, no disrespect meant from my side and I apologize if It came out that way. I was just kind of hoping someone could bump me in the right direction. The last time this phone was flashed the previous owner flashed it in such a way that the sim card could not be detected, after fixing that I flashed a MIUI rom, but that was sort of the Chinese version and stuff like google services did not work properly and push notifications would not work unless you turn the phone on and go into the app. So yeah if you can point me in the right direction I will appreciate it a lot.

Video recording was a issue for Nougat based ROM but it has been fixed.And about gps, it is working fine (i like to use waze)with Marshmallow based ROM.I don't know about nougat as I didn't fully moved to nougat.I have downloaded Tesla (N) and sodamod(cm 14) today .So I will report you soon about GPS in Nougat.
Till now I have tried cm(M),RR(M),DU(M),Tesla(M),orion(M),zephyre(M),AICP(M),AOKP(M).Most of them has kept my expectation.Now I am on project-x(M).It is also suberb with almost no problem.
If you want to stick with miui based then there is also"thunder-miui" by @gkalen.
Try these ROMs and see which is suitable for you.I like to stick with cm based for C.M.T.E.
Edit:-GPS works fine in nougat.
Lollipop (5.x) - CM 12.1
Marshmallow (6.x) - MoKee
Nougat (7.x) - I only tested Suda not good for daily driver

Sleep of death in all Nougat ROMs

The global trouble with all nougat firmware
Hi guys. I amn't alone, I met 10-15 users at 4pda with such problem.
We have the bug at all nougat roms by any devs with different trees...
The sleep of death.
Personally I notice it after/during mobile internet using, but I'm not sure. For long time at home(for a week, for example) with WiFi I have no troubles. But if I am anywhere without WiFi and use 3g(don't have LTE in my country), my phone "sleeps" for some times during just one day... It isn't powered off as it's needed 10-15 seconds of button pressing to turn it on at least.
As the ROM and developer has no meaning I guess that here are the errors in the kernel. @fir3walk says that here are many bugs in our nougat tree and perhaps the trouble is involved in last_dmesg... Or some system force stopes, dozes work improperly.
Not many users have this trouble but it exists an a fact. So it would be great to detect an error and try to fix it. Perhaps not in nougat, at least in new Oreo(I haven't tried it yet so no information about this bug there). We have many ROMs, they are updated for some times a week, new roms are rolling out... But the bug stays still.
If someone else has such problem, write here. Perhaps somebody has any ideas and together we will be able to find solution...
So, all the devs who can detect an error, write us... Any tests, information, logs, etc.
P.S. By the way it is impossible to write logs of powering off(deep sleeping) via logcat or another's. If I run the logging I have no "sleepOFdeath".
It is really global trouble so let's try to fix it together.
I'm sorry for your trouble.
Lets start by figuring out which device is in question
I have a 3s prime and never saw this issue.
So do you have a 3s or 3x or 3s prime?
Hello OP, can i ask if you installed that MIUI Ported ROM based in nougat? Because when i installed it (twice) y faced this issue in every rom that i flashed afterwards, then decided to clean-flash miui fastboot rom and the problem was solved.
Maybe that's your problem.
i face it in rr rom but no in dnd rom
Guys did anyone here with the sod, flash global stable/developer in edl mode?

Hello. No, I didn't try miui based on nougat.
But other users say that they notice such trouble at miui(7 android) as well.
So it isn't the cause...
Also about my phone:
Redmi 3s, 2/16, 2016030, FPC, aa1 motherboard.

Will try to flash via miflash, as I faced no problems before this SOD at 7.1.2. Always flashed my phone via twrp.
By the way, guys, my 3s sleeps well on nougat, but it isn't econom in active mod.
For example, I have made a record at our device at 6.0.1 version - 17.5 hours of screen. Nougat isn't so optimized by now... 10-11 as maximum.

It it solved my voLTE works now
Having a serious problem.....I'm running pixel experience ROM now but I have a tried nitrogen OS, ressurection remix ROM, Lineage OS 15.1, Viper OS (nougat), Lineage OS 14.1 and many other ROMs. Volte was working fine few days ago but for the past 3-4 days it was not working. I thought it was a problem with the ROM so I changed the ROM but still got the issue. And today I came to know that my device is showing IMS registration: unavailable
Voice-over LTE: not available and some other things
I tried messing with APNs and flashed some volte patches but still got no luck. Then I tried searching on XDA forum and know what I tried every possible method in almost all the threads and still not able to get volte. Tried searching YouTube for IMS registration and tried googling it also but still the problem is there.
Help me out plzzzz....

Maybe you need to write IMEI number again?
Does it show there when pressing *#06#* ?
U may try going back to MIUI 9
And then back to your favorite ROM
I did every single step mentioned above. Even my IMEI number is all good. But VOLTE problem reamins the same.
During the first boot...VOLTE was there, and it was working. Even when I Rebooted, it was again there and still working. But when I Power Off the device and then powered it on, VOLTE was gone and I was unable to call.

I did that too and thrice bt the problem remained unsolved. As I mentioned, it worked during the initial boot of any custom rom, even after rebooting it. Bt when I powered it off and then booted it up, VOLTE was gone.

Yeah happens with me to but now m using Xiaomi.eu miui 9 ROM bro use it for some days and flash another ROM voLTE will work fine as it creates a strong bond between firmware and ROM that miui 9 official doesn't and it has more features than it miui 9. So give it a try

Flash any miui rom v8 or v9 & boot into system..
Now go to recovery wipe all except storage.
Now flash any custom rom i suggest lineage 14.1 & boot into system..
Now again go to recovery go to wipe , advance wipe & wipe only system
Now flash any MIUI rom then wipe cache & dalvik
Now reboot...
Volla your volte now works...
I tried 2 times & all time it works....
If it works for u hit thanks..

Wi-Fi does not work on LineageOS 16.0 (Pie 9)

Hi guys,
Everything was working great with LineageOS 15.1 (Android 8.1), but they have discontinued the support for this version and switched to 16.0, and a FOTA update of Lineage from 15 to 16 isn't possible, so I had to download the zip manually, and flashed it using TWRP, around the end of April. Since then the Wi-Fi does not work.
I should explain what this "does not work" mean: I turn it on (either from the pull-down curtain, or from the Settings -> Network -> Wi-Fi menu), it pretends to switch on for 1-2 seconds, and then the switch turns off by itself, so it doesn't even have time to scan the available networks.
I have tried to burn a newer image again, around the beginning of May, but it didn't fix the Wi-Fi problem. I was googling a lot, but seems like nobody reports such a problem.
Any ideas how to fix it, other than going back to Android 8.1? Preferably I'd like to stay with LOS, but if I have no choice, I can consider moving to RR, or AOSP Extended or whatever.
Thanks!
I think its a boot.img problem. I have seen this error in stock too. The wifi/bluetooth used to turn off immediately after i turned them on and the error was because i flashed the wrong boot.img . If i were you i would clean flash the rom again
What do you mean by "wrong boot.img"? I don't flash any boot.img separately, I just flash the whole LineageOS rom (and then Gapps) from TWRP. Should I flash anything else? I don't think so...
Well, in my case at least the Bluetooth works properly (with both headphones and smart watch).
SOLVED!
Surprisingly, the problem seems to be solved now.
After flashing lineage-16.0-20190426 and later lineage-16.0-20190530 versions, where the Wi-Fi didn't work - today I have flashed lineage-16.0-20190704, and guess what? It is back now!
Thought it should be important to update the thread here.

You mean, even if I upgrade from Lineage 15.1 to 16 I need to flash the stock rom first? Why?
BTW I saw some reports on Wi-Fi problem while going back from custom to stock rom too, and there was some patch suggested to fix it.

Because its a prerequisite on Lineage 16, it depends on parts of stock Pie rom being installed.
The LO16 thread also listed a migration step if you didn't flash the stock Pie rom beforehand.

Its on the xda thread, not on the lineageos website.
Xiaomi made some changes during the upgrade from Oreo->Pie and introduced ARB. Now you cannot downgrade back to Oreo easily. Just flashing back to Oreo(stock or custom rom) will cause the phone to bootloop. For the same reason your phone probably faced issues when you flashed (Pie) LO16 without the Pie firmware.

Well, I did not try to downgrade from Pie to Oreo. All I tried to do was an upgrade from LOS 15.1 to LOS 16 (15.1 worked excellent). And I had no idea I needed to flash the stock rom in between, so I just flashed 16 over 15.1, without wiping the data partition (only wiped dalvik cache).
Can you please point me to the XDA thread you mention, where it says I had to flash the stock rom first?
Anyway, since everything works OK now (or, at least, I don't find any malfunctioning, probably except for the native camera app, so I use an external app), I don't think I should play around with it again, right?

Some parts of the firmware might not be overwritten by LOS/stock depending on the version. The original LO16 used Oreo firmware iirc. The thread is not hard to find, just look for it.
