Mobile data problem on Redmi Note 8T - Redmi Note 8 Questions & Answers

Hi. For several weeks I have had problems with mobile data on my Redmi Note 8T. I have always had a good 4G connection. I usually try different aosp roms, and after installing some of them, I started to lose 4G data. To recover them I connect and disconnect the airplane mode. But I don't understand why it disconnects. I have flashed the stock rom again with MiFlash, but the problem continues. I don't know if it will be a problem with some partition. I recently followed a tutorial to reset the "persist" partition with the "persistbak" copy, but it didn't fix the problem.
Anyone know what might be happening? I would really appreciate your help.

Hi.
I don't know if your problem was same as me.
but my mobile networks were lost (both sims, due to changing rom?). I testet two or 3 A10 roms but problem was loyal(!!). but after flashing an A11 (revenge OS) it solved and sims networks got back again.

Thank you. I think my problem is different. I have not lost the data, I just go from 4g to 3g, although I have good coverage. I recently installed Revenge A11 as well, but the problem continues. Thank you anyway

[Q] disappeared LTE all firmware

What is done:
first I flash 30B bump, the problems starte. then flash 30B LGUp, flash 21a and 21c, change band in ingeneering menu, delete lteconfig, flash 30b bump with modems: 21a, 21c, 30b hybrid, change of operator, manual config APN, manual search network. All this does not help.
Any ideas?
no ideas?
Idem.
But after reboot 4G is ok, but again...every morning i lost signal 4G...only 2G/3G is ok. So..reboot & 4G is up......disappointed.
Same on my G3. I downgrade from MM to LP but problem persist.
Same here....tried rollback to kitkat stock, LP stock, CM12, Cm13, and some other roms with no luck....have just flashed stock LP for repair...
so today I tried swapping my SIM with my friend's
he is using G3 with stock 21A, and his SIM is of the same carrier as mine
after swapping, I found that my phone (and of course his phone, too) is working normally
my phone is normal even after swapping back
did some different tests like switching on and off with 3G, LTE etc., everything is normal, at least at this moment
Still working with you? So it is sim card fault? With me after searching networks everything seems to be ok, but I couldn't connect with LTE. Only sometimes successfull connection.(once a day and after reboot same...) Very strange. :/
I lost network signal randomly... i tried with 30b hybrid modem, 21a, 21c... kdz method, twrp bumped rom... and doesnt help me at all.. my network signal gets a rotating circle randomly... and in that time my phone is out of coverage... it is .... hundred times in a day... i dont know what to do, please help
same here when i use sucks 30b D855, but now everything is ok with me.
Steps that have been followed:
downgrade to lollipop 5.0
install CandySIX Rom , then try to connect to my carrier network , at the first time it not give me anything , but when i reboot my phone , LTE appears and everything fine
back to CloudyG3 2.5 then i found that the problem resolved
My phone now works well
OKAY, i found a solution to the problem and here is what i found :

Same here...
Edited: Fixed this deletings the folder LTEconfigs on System/app
Had to then configure it to auto GSM/WCDMA then switch back to LTE auto
It connected at first with 3g then it went LTE and worked normally

Some people got their phones back to normal by flashing some roms (like CM, ACIP, stock, etc.), but that didn't work for mine
not sure if it was sim card fault, but my problem solved (at that time i was back to LP stock 20h) after swapping my sim cards with my friend's.
i am still using that sim card at this moment, working fine since last thursday
Same problem here, have signal drops on MM roms with LTE connection.
Tried all methods above, nothing really helps .. ;((
The signal is fine on LP roms, tho i installed N&N so i was able to change network type to GSM/WCDMA auto, having steady signal now, but missing LTE speed, trying to find solution to fix this, but unfortunately for now.
Same, my G3 doesn't recognize my sim sometimes or it just loses signal randomly, making the smartphone almost useless.
I tried CloudyG3 2.5 Lollipop, then upgrading to Marshmallow with many radios flashed (also the hybrid one) , then I tried to come back to a stock Lollipop ROM and the signal is always unstable. I'm going crazy due to that. I'm starting to lose hope too.
I think I've tried every possible solution to the connectivity problems I've read since flashing 30b.
Freezing LteConfigs gave me more stability, but didn't solve the problem completely. Tried editing the build.prop to force LTE as preferred network type, this didn't change anything. Don't even know how many times I've changed my apn settings.
Tried every combination of modems possible: 21a/c modem with 30b rpm/tz, pure 21a/c, pure brazilian 20c, brazilian 20c with 30b rpm/tz and nothing. Changed sims multiple times, didn't work.
The only way to get a reliable connection is to limit the phone to 3G... but that isn't a solution since I pay for unlimited 4G. If I let the phone in auto mode, the instant it tries to connect I lose all connectivity and it would take up to 2 minutes searching for the network.
I'll flash the stock rom today and if it doesn't work I can safely say it should be a hardware problem.

I had exactly the same problems I tried all of the solutions mentioned modems/roms/etc but what solved it for me was flashing the Pure stock MM kdz now no signal drops or 4g problems.

Did you root after flashing the kdz? I'll try with pure 30B but having no root is almost as bad as no 4G.

No not rooted it yet, to be honest I don't like the kingroot app it looks way too suspicious to me + the rom is smooth and stable at the moment so I thought I would stick with stock for a while.

Unable to catch 4G LTE network after OS Update 5.0.3

Hi,
I have been facing problem of not getting 4G LTE network on my One Plus 5T. And after a while I realised that it's after the latest OS update of OOS 5.0.3. I am in a full 4G network area and my sim is also working fine when I put it into different phone. So I know for sure that it is not a problem of Network or Sim as both are working fine. I have also searched on google abt the same and lot of people are facing the same problem however I could not find any fix or resolution for the same. I have tried clearing the cache from the recovery but no help, also I have selected LTE only thru *#*#4636#*#* but still no help. Any help would be really appreciated. Thanks.
I'm assuming your APN name is correct?
It seems like almost all problems with Oreo updates are caused by dirty flashes. Typically a clean install fixes everything.
If you didn't do a clean install that's step one.
Solved, go to read my tread
Hello
For information:
On ROM O+ 9.0.4, the 4G hook works better on the "Global auto (PRL)" parameter.
Best Regards

Could be persist partition problem. Search on xda for more info.
Good luck and stay safe.

Question No Network Connection (RIL Dead)

Hello everyone. I have a realme GT Master Edition (RMX3360).
The problem I am facing is that, SIM network does not work. SIM is recognised but it won't connect to any network, so basically I cannot use the SIM card even though the phone knows what SIM is this.
I did try:
Factory reset.
Use Force LTE app to access phone information and switch bands (I noticed radio toggle is switched off, I tried turning it on but it won't).
Unlock bootloader, just to increase my chances.
Flash only modem/hlos/... related partitions. Did not work (phone bricked).
Flash OFP firmware. Did not work.
Flash EDL firmware (C.09), which I am currently using. Still same problem.
Different SIM cards.
My IMEI is fine, it is recognised. My baseband version is 4. I did search for the issue in realme community, and it seems quite popular as a lot of people suffer from the same issue on different models.
I live in Sudan, we got no 5G, no VoLTE or whatever. Could you help me please?
I have similar problem after reboot .I can't connect to network or it tooks long time . What helps me is switching to airplane mode.

Switch to global rom maybe your sim card provider not supported switch to Rx3363

Thanks for the suggestion. I did install RMX3363 EU ROM from EDL, it booted fine but the phone still won't connect to any SIM network.
I will also try Russia ROM to see if it would make any difference.
Update:
I did flash Russian ROM from EDL, still does not work. Modem version is also still 4. I will try Chinese ROM next.
Try Latam version this what they put in middle east but so far i think its hardware issue did u try the sim card on another phone? Did you try another sim provider on your phone ? Sometimes if the sim card too old it wont work

That LATAM version is 18 Gigabytes haha. It'd take a few days to download.
I came to think it might be related to modem images as it showed the same version repeatedly on both RUI 2 & 3. So I'll try different modem images.
Also I'll try custom ROMs and GSIs. If it failed I'll return the device as a very last resort.
Update:
I tried latest Official ProjectElixir till date, still same problem.
Update 2:
I gave up the device and replaced it with another one under warranty. I will not buy another realme phone anytime soon.

Sorry for your experience i have the phone also its okay
I was using Xiaomi phones before miui is better software than realme
But after Xiaomi remove the proximity sensor from there phones i start to avoid them

I have a Xiaomi device too. The new virtual proximity sensor depends on hand movement to function. I don't use MIUI, but it is very fine at all situations.
Also I got a (256/8) GT Master replacement which is surprisingly working fine; being the same RMX3360.

It was already updated to F.03, I heard there was screen flickering or something but I didn't notice any so far.
But I did notice the battery was draining fast on mobile data. Really fast.
Besides, I can always lean on post-market development.

The general feel of the update is slower than the android 12 version
The battery will get better with you try to froze the app you dont use
