MI A1 Network fluctuation with custom ROM - Xiaomi Mi A1 Questions & Answers

Hey Folks, as we all know how stock ROM sucks, I remained on custom ROM to max extend. But sadly I have to revert to stock due to network fluctuation issues. I use Jio as my primary and Airtel in SLOT 2. Fluctuation is widely seen in slot 1 which is reported by many others as well in respective ROM thread.
I have tried methods flashing custom modem image and network signal guru. But none seems to fix the case.
Anyone aware of other methods to fix the network fluctuation issues seen in custom ROMs? May be using any custom kernel?
Please help me to remain in custom ROM!
Cheers,
Hari.

Same here all cust rom has this network fluctuation issue and it is to do with the code. It seems if any one can fix this. It will be great..

The same, please helppppppppppppppppp!!!!

Noticed the same on Vodafone AU, no matter what network mode I set it to. Even on 3G only I get drop outs and fluctuations.
I'm hoping it's just some extra modem related package or service missing from the vendor blobs, but I've not had time to look into it yet (with my limited skills in this area).

For me also lot of fluctuations. Sometimes totally black signal bar. Hope somebody can fix it. I fixt it for now with automate and set network to 2g when on wifi and after lock screen when I am on mobile network.
Modem zip in forum don't solve it for me and also lock some bands with signal guru didn't do the trick.
Hope somebody can solve it a lot of people are suffering this problem.

Has anyone tried using custom kernel? Just curious on if any custom kernel fix this.

Same issue I have been facing, I had re-partitioned my device for Treble using CosmicDan's guide so that I can try all the best custom roms out there and get all updates as they are released but when I faced this issue, I had no choice but to revert back to Android One rom, undoing all the process

Probably resetting modem settings, assuming you've made any.
China only uses maybe 5 bands, and most of the population doesn't often travel far from home; so roaming and tower switching isn't an issue. That, and a power management issue I think are responsible for our network issues.
My money is on these devices working perfectly in the motherland.

Faced the same , almost on every custom ROM .Jio 's volte doesn't work most of the time. Switched to January stable stock twrp with magisk . Now everything is stable , no volte issues at all .
Now my question is , the issue is with ROM or modem file ? As you guys are saying that it is a modem issue ..as now I am on January stable modem , I will try to flash a latest build of any custom ROM and will report .

There's a TWRP flashable May modem patch somewhere in the MiA1 forum. I've flashed it and the results aren't perfect, but circumstances have improved.

I have tried all March, April and May modems and all have problems with custom ROMs and network fluctuations for me. (IND Airtel operator) and even 3G is fluctuating with state owned BSNL. January is the only one I haven't tried which I will after getting a reply from sikoo1996.
I have very limited knowledge of these matters and so far all my attempts with dialer code menu or settings or Network Guru have all failed. Guess I will ditch this phone and stick to my S5.

Rit now I am on jan stock build , means on Jan modem .I will flash a custom ROM now ..later today and will report back about the issue .
Cheers?

I dunno if it actually works for everyone but,
Swapping the SIM card slot worked for me.
Using RR latest. I also flashed stock modem.img but that didn't fix the problem then. It's fixed now by swapping SIM slot.

Hey guys. Try flashing the latest modem and then, go oh ahead to *#*#4636#*#* and select network mode to TD-SCDMA/CDMA/UMTS . ?

[Q] Network problem after flashing I9505XXUBMEA

I am in Singapore on Singtel network.
I flashed about 10 days ago the I9505XXUBMEA rom from Sammobile.
Since I flashed I have had very very poor signal (voice : calls not going through or calls dropped and data : close to no data at all) .
I have a limited experience with flashing roms.
I have checked that it wasn't something related to my network or card by switching the sim back to my GS3. No issue there...
I tried to flash DX... modems with no change...
Can someone help me ?

I would suggest Reset the device completly which is suggestable after an update
And see mostly some bad system file would be causing this Reset from device will clear finger crossed
Note: Data will be lost incase u do reset back important things first
Ok, few more solutions for you.
1) Try a CSC change, not sure if that has any effect on your network. Find one that's for Singapore or SEA region.
2) Try flashing a rom from Dejembey's, haven't had any network issues there. http://forum.xda-developers.com/showthread.php?t=2250824
I'm on MF8. Maybe you should give that a try.
Ohh and please share your wiping procedure you tried earlier.
Cheers.
I flashed the new rom without problems.
I am still mainly stuck on G for the data...
It might not be the rom or modem...
Any ideas of what could be the cause?

[Q] Data Drops During Calls. Please Help.

Hello guys. I have the n900t, I am now running tweaked s5 base n4 style v6.0. And I run alot of n9005 ROMS as well. With that said here is my issue. For only the past few weeks ( month tops) every time i make or recieve a phone call my data drips down to hspa. The second i hit call and right before my phone rings is when it happens. After my call the data takes a very long time to jump back up. This is a new issue and i have no idea what it is. However, i did flash back to a stock ROM and the issue was solved. And i forget which rom it was but it was soley TE based and there were no issues. I did try to flash a modem but it didnt take. Is anyone else experiencing this problem? Or can anyone suggest a fix for it.
Thank you for your help.
bump.
Still having the issue. I tried to flash a new modem and it just failed anyway. Dont know if I should try a radio. I just cant fivure out why this happened out of no where. I was fine no matter what ROM I was running. Now...this crap. Please guys, 40 people saw this, can SOMEBODY please help.

1) Quite strange - your picture suggests you are on Verizon yet you comment about a N900T in the forum for the INTERNATIONAL Note 3. On what network are you? Are you aware that there might be network-specific factors involved which could only be visible for other users on exactly the same network in exactly the same region?
2) Try stock ROM (with corresponding stock modem) from a location with very good signal.
5 he physical device is an n900t, however, I am running as of now, the hyper drive note 5 port with n4 UI. When I do flash back to a full stock TW ROM all is good, A FEW TW based ROMs seem to be OK. Like this one, the calls do not affect the data signal. But most ROMs do effect it in that way. You said that it shows I'm running Verizon?
But I am very curious why all of the sudden I am having this issue. I have never had it before. Except with a few specific AOSP based ROMs. I just can't figure out what it is that's causing it. I have done vigorous wipes of the phone to no avail.
And I am in Philadelphia so there really is no place that is actually bad reception (except in the susubways of course...lol)
And thank you for your reply.

1) Your avatar mentions Verizon for some reason.
2) If it is all OK with the stock ROM then it is a problem with the custom ROM, ask in the specific thread for that specific ROM. Most likely it has something to do with the modem and the corresponding RIL.
So when ever a new ROM is flashed the modem is flashed as well. Unless the dev says otherwise?

Redmi 3s Prime data speed dropping to E and G

Hi all,
I have bought a Redmi 3s Prime last week. One problem I am facing is that if you turn on data services, if it is idling, speed drops to E and even G. The only way to get it back is to manually change network preference type from settings. What could be the problem? Is it a hardware issue?
Android version 6.0.1
MIUI version 8.2.5.0 (MALMIDL)
Please help.

This is a known issue.
Is you have root, try to install Networl Signal Guru, then disable Edge (2g) frequencies.
Some people solve it using a second sim...
Second SIM even if dummy one will solve this problem, I'm using this option and managing my 32GB wisely as you will lose your sdcard slot. Nothing terrible for me as I need it the 2nd SIM anyways.
slds,
Your problem is well known, but still no solution from xiaomi.
Best i can suggest is that u check which frequencies your carrier uses.
If u got root, install Network Signal Guru.
Try disabling one of used WCDMA frequencies and then force 3G. if it doesnt work, try to disable the other frequencies
IT WORKED FOR ME D

Switch to global dev rom you will get the latest one. Miui 9 v 7.9.8
Better you make clean install with MiFlashTool via EDL.

Moto g5 plus, single SIM, no LTE on custom ROM?!

Moto g5 plus 64g (single SIM),unlocked bootloader, root...4g works fine on stock ROM rooted w/Xposed
. ..and that's great but Ive flashed custom ROMs
Resurrection
...and Halogen
... and Desolation
... and they are very nice ROM s but I only get 3g (no LTE) and the only info I find on this is a quick-fix w/jio SIM using a DUAL SIM. .... Am I the only unlucky human w/a single SIM 3g problem?
I was so excited about this phone, thought I did all of my research , bought TWO 64g g5 plus phones(not 32g no way because I wanted to BEST lol but its single sim, stupid me).
...should I just give up on custom ROMs ? ...or is there something can be done?
Ive being at this for 2 weeks now...Any/all info very appreciated.
I would've posted in other forum but wouldn't let me due to lack of status....or rep...or bling..or something.
Do you have correct APN set? On some custom ROMs I have installed I had to change APN, because it was set to first in the list by default.
I dont know much about APN ...not durecwhst it's suppose to be set at..im boost mobile.. I'll start researching that next ..thanks brother
No luck.
I found the APN settings on Boost mobile site, I set/saved that to no avail.
I went back to stock/rooted and 4g works fine. But no matter which custom ROM I use I still only have 3g.
Surely someone somewhere knows how to set/fix this.
Can a Mod move this to where someone may have hands-on with this 3g vs 4g issue? Dev or someone?
Month later...5 custom roms later...still either no 4g on custom rom or no camera on simple root w magisk. I still can't post in Dev forum.
No LTE

Have the same problem, how did u go back to stock? TWRP restore? or did you fastboot flash stock fireware? I'm not sure if it makes a difference but after reading a few of these it looks like stock firmware may need to be reflashed with fastboot then start flashing custom ROMs with twrp. If you get the answer let me know if i find out I'll let you know?
Thanks
Update: yes there are ROMs that will fix the LTE problem, I was reading someone with a connection problem someone suggested downloading stock debloated , another suggested AOKP, downloaded both , first I tried debloated got LTE , then flashed the other, for VoLTE. Also I'm not sure if this is correct or not but fastboot flashing modems may work I'm not exactly sure and would need to look it up further is something else I read but didn't try as its 2:00am and I'm being yelled at by a hidden speaker in my kitchen which is why it took so long for me to even try to look for a reason because I've been getting yelled at so long I think I got cancer, I hope Santa brings them a tall glass of shut the f up so I get one day without being yelled at , also Lineage 15 says LTE working. I haven't used it since I don't want to mess with 8.0 right now. MeryXMaz
I'm havin the same issue. Also with Boost Mobile. Most other devices I've rooted have had some sort of boost/sprint/virgin APN fix .zip. But I donno....

Thanks for responding. I still haven't found a fix for the LTE. I will try to aokp again maybe something has been fixed or added. I did fix my camera problem by flashing elementalX so that's good. But not having LTE is not cool. And I also did not want to message w 8.0 yet.
So I tried AOKP to no avail. Still no 4g/LTE. That's time I'll never get back lol.
had the same problem XenonHD seems to work well...
I'll try it thanks
Hoping it'll get better with the official 8.0 release.

[CLOSED]No Signal and No service after flashing custom roms and mods.

Couldn't get the help i needed . I am about to repost this in Discussion Forum . Thanks everyone for replying !
try flashing the stock rom...maybe u would get it with that..the again flash your desired custom rom
I have the same problem bro. In my case, I lost the Volte facility due to this and I only have the 4g LTE now which can just be used for internet. Follow the steps at https://forum.xda-developers.com/g5-plus/help/restore-imei-0-moto-g5-xt1687-t3739808 to get back your signal. As for Volte, there is no fix as of today.
Thanks for trying to help.. Really appreciated.. But i didn't lose my IMEI number
I have the same problem but on my 4g plus my sim won't work with custom roms as it's a cdma sim only ones that do work are stock custom or stocked tweaked roms so what you can try to do is go back to stock and see if your Sims work again.
I had the same problem. FIXED installing crdroid 7.1.2. Latest firehound works intermittently. Sometimes it works and sometimes just doesn't show any sim.
I can get the signal back ..but it's doesn't work forever... As miguileto133 said !!! ..sometimes signal comes back after wiping cache. But it doesn't always work..So I am gonna try flashing stock then again Will try to flash custom ROM ..if it again fails to get network.. I'll have to choose stock for life ...which I don't want :'(
