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 5 pro SIM and WI-FI not working
Hello, my friend has a Redmi note 5 pro and one day suddenly wifi and sim card stopped working(that's what he told me). I flashed recovery rom(MIUI 11) and sim and wifi started working back again only to stop working again a day after.
Then i flashed fastboot rom with mi flash tool(WHYRED GLOBAL) and the flash went on forever.I then flashed again with 3rd party flash tool and it showed success message but after i boot up....sim and wifi are still not working.Also i can now no more enter my phone because of no network and mi account lockdown. What are my options?
Bootloader is still unlocked.

Well as the title says.
Just rebooted my s2 and now when I try to do anything it says "insert sim card to access network" imei is fine serials fine and even shows signal bars but soon as try to make a call to drop signal and network completely....
have restored efs folder and even dne a repair.
changed base bands
reflashed new rom
tried different sims(and networks)
and still nothing
Odd that it happened after weeks of being fine and then just did a reboot and then this all happened
any ideas folks as to next move?
please someone must have an idea or two. to offer!
Well looks like I have fixed the issue after many hours of frustration..
Still have no idea what happened to cause issue in first place..
What I did was refresh my original backup
flash original STOCK rom via odin and this seemed to have fixed it. Are there any friggin better loctaion for these files as took 8 hrs to down load the damn thing!?
now re rooted, flash custom rom, flashed custom kernel of choice and than restored back up
everything seems ok(though my imei is incorrect now as says 004999010xxxxxx ,but am concerned it will happen again. Had flashed a modem several days before and updated a few apps . but at time of the issue occuring was just clearing caches then a reboot..
So,
I bought this phone on the day it was launched, its been more than 3 months and had no issue with the device. I rooted the phone , experimented with Xposed and other apps but for the past few days i was experiencing this strange problem. Cellular network was not running on my phone, i changed the sim, swithed the devices on/off several times , did everything i could do in the os, changing the mode to 3G from LTE and vica versa, etc etc .. but still no luck. The cellular network sometimes comes and goes. Then i opted for last resort which was to factory reset the phone, after resetting it the cellular network worked but i don't know if this is a permanent solution. If you have anything to add please share.
Regards,
Saransh
Sorry nothing much to share but i suspect you install some apps or did something to your rom so the network screwed. My suggestion is you nandroid backup every week (at least) so you can revert back when something happened.
Tried factory reset
I have tried factory reset but still having this issue. Maybe it's a hardware issue. I don't get it , everything was working fine few days ago then all of a sudden this **** happened.

Maybe exposed screwed something. Get a microsd card with whatever rom you want in it. reboot to recover and try full format. insert the microsd after then flash a rom. see if it works
Rooted my phone with sudamod rom, Everything is working fine.
I encountered this problem about 2 weeks ago
I have flash every ROM (Official, MIUI based custom ROM, and AOSP) including in fastboot mode
and only CM12.1, CM13 and RR survived from random reboot
I won't use both CM13 and RR because its RIL
Now i used CM12, but I have super fast draining battery
My phone will die, even in standby, because Android OS and System used battery more than SOT
When I checked it, the CPU always stay awake and won't enter deep sleep, so my phone always went heating even in standby (screen turned off)
The only problem I would fix is the random reboot issue when I used MIUI and other Custom ROM I had mention above
This is driving me crazy. Does it hardware problem or something?
If not, how to fix fast draining battery from CM12.1?
Sorry for my bad english

Hi, i'm having the same issue as yours, have you try to send for repair? Xiaomi centre at my place refuse to repair it as mine from china set, any luck at your place?
Edit- mine was unlocked officially, don't think it related to this issue as it was working without any problem previously,the last thing i did before this happened was making a call in lte before it turned off suddenly, then heat up a lot and keep on rebooting,

Will try to send it to repair shop nearby and hope they can do something about it, it's only a month and now it's completely unusable, maybe just a bad lemon unit

Goldway store, aliexpress...I am still in the protection period so i think it won't be difficult to obtaining a refund...But still i prefer to fix it...
I think is a hardware problem though...i think it has something to do with the energy or temperature managment or circuitry...

Should be hardware problem and there's nothing we could do i guess, there's a few people affected already.. problem with this model and we're the first.. so sad. Luckily my nexus 5 still going strong despite the screen shattered, even can see the circuit inside, showed the difference between brands quality.
Did someone with this problem can Instal CM13 ROM with fingerprint compatible?
because mine always stuck in Mi Logo and then can't enter TWRP until it re-unlocked and back to MIUI with Mi flash to able flash TWRP)
If not flash fastboot MIUI, the TWRP can't be installed even the phone have unlocked
WTH is going on with my phone

Try flashing global stable through MiFlash and tick the option flash all or equivalent.

Thanks Ivanlai,
What Exactly do you mean by your answer?
did you had this Problem on your Xiaomi Device?
had you manage succesfuly solving it?
my device is new and i dont want to do something that will harm the Warrenty.
I haven't had this situation exactly, but the reason I said to tick flash all is because I have bricked and bootlooped my device before.
By ticking the flash all option, it reduces the risk of some remnants of the previous ROM causing conflict.
Also, I tried several different global stable ROMs before I successfully unbricked my device.
As for warranty, I remember someone mentioning that a xiaomi customer service operator emailed them saying that rooting and flashing custom ROM would not void the warranty, but I would email them again on this issue just to make sure.

Thanks Ivanlai,
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 also bought my Redmi 4 Prime from goldway store, do you know what is their return policy like?
I've installed the official Nougat update from Elephone using the SP flash tool. Before the update, everything on the phone was working.
After the update, the phone boots Android 7 fine, but no SIM cards are recognised.
I've tried entering Engineer Mode through the phone app to reset the IMEI (I know what they are) but the 'Connectivity' page in Engineer Mode doesn't list phone radios, only FM, Bluetooth, NFC and WiFi.
So I rooted the phone and tried entering AT commands through a terminal. But the folder /dev/radios is empty.
It's like my phone has no... well, no phone. I guess the driver is broken somehow.
Does anyone have any tips on how to proceed?

Well, there's one who didn't read the question. This is not about restoring the IMEIs.
Alright. I know flashing nougat might break the radios and also IMEI. This includes not detecting simcards. I had this problem myself.....
I have the same problem, or similar .
I can sometimes send and recieve text messages and sometimes i can call. Data traffic seems to work ok.
Right now as soon as i try to make a call i lose connection to the mobile network.
Theres a simple fix, reflash 6.0, then do format all + download android 7, imei wont be restored, but both sims will be recognized and work normally

that seems like a hardware issue, i think theres a few cheap speakers and you could try to fix urself on ali express theres speaker at around 10$ it ahould be farelly easy to replace it
I've had this same problem, but only after replacing my screen due to damage. Ever since then, it'll see the sim but wont connect to my network.
Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...
