Sprint LS990 Roms Network Problem - Sprint LG G3

All these Roms including zv4 and zv8 on Ls990 Showing In Screen shot in Pakistan working Smooth without simcard but with sim starts bootlooping sometime signals appear then again starts bootlooping. Now iam on Lion Rom User interface is good but network problem .

use fulmics or cm13 im using fulmics 5.3 without any issues on zong.

Zong is not working in our area and Iam using warid CM13 is working for sometime and then again starts boot looping .

Its battery problem
Brother, this is not a network problem, its battery problem. Replace your battery. I have same problem start with same as you have right now. Than it became more and at the end bootloop with my old battery. I searched google and found that its battery problem. I replaced battery than all problems gon. At the end avoid flash lot of custom roms day by day, that is another reason to damage battery, specially dont often use battery calibration app.

I have the same issue network problem signal bars showing for two minutes and after that showing litte cross and this process continues till now on every rom like cloudyg3,euphoria,cm12 and fulmics dont what to do tried everything but didn't find any solution

This thread should be in the Troubleshooting section.
Also, you can screenshot things on your computer.... taking a picture of your computer monitor is just blurry and lazy.
With that said, I would have to agree with a previous post that you should start by replacing the battery. If that fails, come back to us with much more information so we can help you out. (and in the right section)

Simcard on ls990 is for your 4glte only. 3g cdma is different not based on your iccid number.
What are your APN settings? And what cdma subscription do you have selected .... ruim/sim or nv?

Did you replace the battery and was your issue resolved?

Modem/Radio resets after phone calls.

Hey guys, tried searching everywhere for this answer. After every phone call my radio resets each time. Started happening on CM11,then on ART MOD rom, and so on. Even tried flashing Stock LG ATT 4.1. I tried flashing different modems, stock att, hybrid , lte hybrid and so on. Any other ideas?
Thanks!
AT&T doesn't support voice over LTE. Every time you make a call, it switches to H+. Its supposed to switch back to LTE after hanging up. I had issues with it under artmod and the other kitkat stock bases.

Thanks for the reply!
Did your modem reset to were it would show no service and no data, then turn back on to H+ then LTE?
Mine will do this ever so often.
No, it was instant.

My question to all the developer here... can anyone help me please? i have LG Optimus G E970 at&t and having serious issue as it is not detecting sim network, everything is running fine except sim network. I was on stock and all things running fine but i installed 4.4 kitkat rom from this link: https://yadi.sk/d/F7yqEV7yaFk8V
then my network not worked, i restore back to stock 4.1.2 but still same problem, no sim detected, i showed it to market developer and they said it is hardware issue while i told them its happened due to installing rom and one have tried on it all things as he was software engineer but no luck, then i gave it to repair shop and they changed its sim jack and insert everything perfectly, but still no network! though one changed in that now when i put sim its not showing but when i eject sim from the jack while phone on the message comes "Phone will restart to use GSM network" and then phone is restarting but same problem , no sim.....!
can anyone tell me exact solution for this? is it really hardware issue or software related? i m stuck up and spent heavy amount on it and still on risk.... i will appreciate your kind cooperation.... thanks in advance..
I have a temperary solution.. hopr it help
I have the same problem and tried everything I could...
If you are in a city area just flash .48 or .54 nexus 4 radio. You get your sim working and can call...
But this will have bad signal strength in Idea 2g network. All the best.
i'm also having the same problem. after every single phone call, the modem resets and the only option is to reboot it. downloaded the latest nightly and did a factory reset and flashed it but it still was re-setting. going to go back to stock.

Problem: Network signal unstable/weak

Hello all,
I do have the following problem which is not new and mentioned in other threads but there is no solution and the threads are quiet old - so I hope it is OK to start a new one:
My LeMax2 is constantly dropping the network signal and the signal is in general very weak (I can only get calls outside, Internet is working irregular "sometimes", outside only. After arrival signal was fine. No difference. Flashed a couple of different custom roms, still fine. Ended up using SmallEUI. After a while (maybe two weeks) signal dropping began. What I tried so far:
- Flashed alternate modem file from SmallEUI, no difference.
- Switched rom back to india20s. Problem stayed the same. -
- Switched to LOS13 (which is still running).
- Entered *#*#4636#*#* switched and set GSM/UMTS band to automatic. Problem got worse.
- flashed various modem files, no difference
- renewed APN settings. No difference.
- Found about 4 threats regarding this problem, can not find a solution. This is exactly my problem: https://forum.xda-developers.com/le-max-2/help/mobile-network-problems-le-max-2-6gb-t3507500
Help? Please? What can I do now?

Have you looked into your carrier? Maybe it's not a device problem..... Try a signal app to see if your connecting to the right bands, getting a good enough signal ....
Have you tried a factory reset?
When I was with T-Mobile they cut service in my area without letting customers know, I ended up buying a signal amplifier for my house to finish out my contract.

Hey,
thank you for your reply. I put the SIM card into another phone and it worked like a charm. So I think it is not the carrier. Rechecked the APN settings also. Regarding the LTE band I am not sure. Most of the time I only get a H+ connection so no LTE band at all. Thing is: The connection was really good with this phone in the beginning.
Factory reset: Yes, and even more (flashed 6 different roms I think and various modems)
Best,
TOM
x829 no signal
i lived in ireland i have x829 from banggood i don't have networking signal strange when i when battery is 0% turn off phone after Charge the battery signal come back for few minutes after again disappear
I have the same problem. I am living in India, and the signal drop is very frequent.
Earlier i only used to get H+, but from few days i get the LTE band but the signal fluctuates almost every second and very unstable - especially the data. The whole mobile network keeps dropping also frequently. Been a pain in the but*
Using RR v5.8 official
This thing solved the LTE stability problem for me:
Type *#*#4636#*#* on the dialer
select phone info
Click the menu on top right on action bar
Select radio band and select band 43
I get decent speeds with some sudden boosts from time to time. PS I am using Airtel in India.
I have the same problem. I am living in sri lanka, and the signal drop is very frequency The whole mobile network keeps dropping also frequently. Been a pain in the but*
i wish to get updates on this problem, cause this is a pain. tried every method mentioned. tried different new roms (rr, LOS, Eui, stock 26s and 21s roms)
Maybe someone has solutions?

Hey, did you have success in resolving the issue?
I had problems too with my le s3 x626, it didn't recognize the sim card anymore, froze, and had to force reboot. Luckily, it was a battery issue. For some reason when the phone goes under 10%, it does that. Easily solved upon charging (happened more than once).
Same issue in the philippines
Heyyo, I'd recommend looking into AEX as @shivatejapeddi recently made a bunch of changes for VoLTE and carrier settings that might help.
Otherwise? It could be your carrier might need further apn and carrier configuration changes in order to work at least on custom ROMs.
Another thing to try? Replacing your /system/etc/apns-conf.xml with this one from the Pixel 2 XL. Download it > reboot to TWRP > mount system > make a copy of that /system/etc/apns-conf.xml somewhere as a backup > replace the /system/etc/apns-conf.xml with the one downloaded > reboot to system > reset apn configuration to defaults to force ROM to reload apns-conf.xml

Please try the above apns-conf.xml to see if that works
Has anyone found a solution for this problem? I think I have tried every rom and every medem file but no luck...The one thath works best for me is EUI 30s from Crisbal, but still i some times lose the networksignal from time to time
I hae let phone here I CANADA. same prob. Phone ..drops service every 5-10 mins. Carrier is not the problem. As.ive tried many
same problem
leeco le 2 x526 : signal if is starting , after i enter inside building ...it drops instant .... try different stock roms . version .and custom roms (now i am on RR 6.0 - good for camera ) .....baseband of my carrier are recognise , 5 diff. modem firmware .... nothing .... any sugestion is worth trying ..... lets find the solution together .
Ok this is super weird but the Leeco Le Max pro I used had the same issue. BUT. When I'd switch on the hotspot, and let someone connect to my Leeco, they get unrestricted LTE speeds. I cannot use my phone data plan but others can using my wifi So. I don't know exactly what's the issue. All those with this issue do check their hotspot capabilities. Thank you.

tried everything, the last one to do for me is REWRITE IMEI on the phone, i noted a strange IMEI=0 or some difficult in reading it (x526 from myefox.it)
Dialing *#*#4636#*#*
Hi devrookie,
I did it as you mentioned in your comment above...didnt worked
Selected radio band...there is no option of 43 infact there is nothing to select...
anyone got this resolved guys? i just bought two leeco x520 phones and both have the same issue. wifi keeps dropping over and again every 10 seconds or so. It's like a loop........ drop .. reconnect .. drop .. reconnect .. and so on. tried two roms so far, currently on lineage os 16.0 and have the same issue on this rom too. on top of the connectivity problem, a new problem has came up .. the phone shuts down while playing games which is super annoying. and the phone heats up a lot while recharging the battery. i'm so fed up

Problem connecting to mobile network

Hello
I recently purchased this phone for a family member. We set it up yesterday, and found that the sim card from their old phone that we've inserted isn't capable of allowing the phone to make/receive texts/calls. It just says something along the lines of "Can't connect to mobile network", despite showing signal bars. When I checked the connectivity bands against the mobile network's, it appeared that the phone should at least support 2G & 3G. I'm in the UK and haven't modified the ROM.
Has anyone had this issue before, and does anyone know of a fix? I've heard that some of the newer official ROMs are better for connectivity, but I don't want to flash the phone and void its warranty if the fault lies with the phone.
Many thanks
Luke
Heyyo, hmm can you please provide more information?
Link to the exact product purchased
What country and network is being used?
Does your device say x820, x821, x822 or x829 on the back of it? If not does it say what it is in the settings > about phone menu?
Can you please specify which version of EUI ROM it is running? Should be in Settings > About Phone.
As for upgrading EUI ROM versions? That will not void warranty as long as you don't have the x829 with EUI ROM 5.8.016s.... which is what I had and x829 with 5.8.016s is garbage. So many darn problems with it and has software updates disabled even via recovery update.zip... I didn't stay on it long since LineageOS 13.0 at the time officially came to the x2 heh

This is where I ordered it from: LeTV LeEco Le Max 2 X820 5.7 inch 4GB RAM 32GB ROM Snapdragon 820 Quad core 4G Smartphone
I live in the UK and the phone's using a Tesco Mobile SIM
The device is the X820
I don't have the phone with me right now, but I believe the EUI is 18s
I wasn't aware upgrading the ROM version didn't affect the warranty, that's nice to know
Hallo,
I believe I might have the same problem with the mobile network. In my case, I am quite certain that the battery is the problem. I got the phone some weeks ago, but I assume it was laying around for quite some time, which might be not very beneficial for the battery? Anyway, the voltage should be 4.4 V after loading and as long as the voltage stays above about 4 V, I have good data connection. But after a while, the voltage drops below 4 V and I do not have any connection anymore, despite showing all signal bars! Is it possible, that you see a similar behavior with your phone? If you load it on a charger, does your data work?

I personally do not experience this but I'm 100% sure that the voltage from the battery should stay around 4V. If this happens try turning on the battery saver and dimmer your screen so you can spread the battery load. Maybe it will work idk.

You are probably right in saying that the voltage should stay around 4 V. This is probably the case for new or at least well aged batteries. However, that seems not to be the case of my battery. According to the App that reads out the voltage, it sometimes drops to values as low as 3.6 V. Sometimes, the voltage recovers a bit, but typically, not enough to enable data connection, for which I believe to need at least around 4 V to work (reliably!).

I purchased a X820 from China (TomTop.com) and the junk had an EXTREMELY LOW signal.I NEVER received network signal at home.I have to go near a cell tower to get signal,as soon i drive away from the tower (around 5 blocks)i lost signal and could not make or receive calls..Remember that the company LeEco went out of business and the phones we buy today are NOT made by LeEco but are made by many private factories in China and in reality are cheap clones.I send the junk back and purchased a X829.Now i have very good signal and connection never dropsJust return your phone is defective..Here is a video i had to send to tomtop.com in order to get a refund.

I have exactly the same problem when the phone's battery level goes around 70% (~4v).
i.e. when battery drops below 70%, the network signal shows LTE with around 3 bars but there's no network connectivity and can't make/receive phone call. But as soon as I plug in the charger, everything works perfectly! This happens on all ROMs.
I wish there is a solution for this.
same problem for me .....
Today ,
NO WAY to have working Network mobile on a Leeco LE 2 x526 with last stock rom 28s installed on it. NOW i can call on 3G but no voice ,,,,, but i can't be called. .....after restart with / without APN / searchable 3G/4G network Digi.Mobile ...signal is lost and is cost me allot of time and energy . i even lost any hope .....(coul be a hardware problem ?)
Operation made until now
1.install 3 stock roms 19 , 21 and 28
2.install another 6 custom roms 6,7,8.1(miui , havoc, lin14.1 , 15.1, aosp extended ,Bootleggers. RR , Cr ,Small_EUI ,purenexus,cuoco )
3.reset SIM 1+2
4.sparse india image
5.write lost IMEI
6.write new baseband with DFS
7.flash modems firmware (MPSS (56347 , 61295 , 66782 and 68083))
8.try other Carrier SIMS ..... same problem
9.check any carrier server service ...nope
etc (rewrite a qcn file . different APN config , twrp 3.0.2.0 ydss )
I have real problems .....i need help (maybe someone have same problem or has read more infos from so many forums )
The same problem.
Only one person with name AGATSU83 something like this find the solution , and the solution never post it.
He help him LAZYE.
BUT I NOT UNDERSTAND he give us one site in russia and he told us that he find the solution.
I READ AND READ AND READ .........
BUT NOTHING.....
I BRICK MY PHONE 20 TIMES AND NOTHING.

I believe your phone is a X829. Someone installed the X820 firmware to sell it easier. It doesn't have Band 20 for 4G. Tesco mobile is working on O2 network and they're using Band 20 for 4G network. Despite that it should work on 3G. In my opinion you should install a custom ROM and check things there...

Phone lost signal

Hello guys, i am under OF1 and using the Stang5litre note5 rom which was working great until i somehow lost all signal . I was trying to make 4g to work , after i entered my carriers apn settings i had really slow internet speeds ( edge) .
I downloaded an app called Advanced signal status and i switched to Gsm/cdma and i had H+ which was alot better. I kind of followed this thread https://forum.xda-developers.com/galaxy-s4-verizon/general/how-to-make-verizon-sch-i545-att-t3267687
I dont know if i messed with any other setting ( i think not) and after a power off my phone had zero signal ( a forbidden icon like this forbidden . I cannot make or receive calls and i cant use data. Oddly once in a while i get some sort of reception of signal ( like 1-2 lines) but again no data. I wiped cache and factory reset from recovery , but problem was still there...
Bottom line, the phone is unusable..
Any ideas?
P.S. ( i searched in the forums and couldnt find something really similar to my case , so i started this one )

yes , it was working ok for calls, and after entering apn settings data was working but suddenly everything stopped. I wiped and problem still there..
If you have a AT&T or t-mobile SIM, did you set the mode from CDMA to GSM in settings? What bootloader are you on? OF1, GPL1, or another? If you did a factory data reset, then redid the APN, it should work. You will get that annoying message saying "SIM not from Verizon" though.

Had the same thing happen to my S4 running that ROM, but I stayed on Verizon. Tried other ROMs, flashing recoveries, modems, etc and manually changing settings, but always same problem with no signal even when trying a new Verizon SIM. I came to the conclusion the modem got fried by it somehow.

Well as I say in the OP i am under OF1 , i did a factory reset offcourse i still have the note5 rom and redid apn settings but nothing works(no signal no data) and the message is not there, that is something i like about this rom.

wow , that is really bad news . i ordered two new signal cables, just in case ( they were 1,5 usd) cause i have also replaced display and maybe i messed with them a bit , maybe i will try to reflash stock rom.. though i really hate this rom. The thing is it was working perfectly. Something i didnt mention is because i live in a humid environment and while repairing phone and maybe because the chinese frame wasnt that good from one side there is a gap that lets humidity in, (never spilled water in it , just humidity) , making the touch unusable. So i heated phone at 45-50 C( 113-122 F) which is not a very high temperature , and it fixes the problem , have done the procedure 2-3 times and never had an issue. maybe this time this was the culprit... I found this solution online somewhere and i didnt think it might be dangerous, so i tried it. Anyway it stopped to work after this iirc.. Sorry i failed to mention that
By the way Camparks what do you mean "fried your modem " ? How is that even possible? i mean by just installing a rom . I am not saying that i dont beleive you, just that it seems a bit strange .. doesnt it ?
What about this? maybe we should try it?

Try the stock ROM (even though it sucks). I'm with AT&T, but I slapped my SIM in my Verizon s4 and everything worked except mobile data because I didn't mess with the APN settings. I'm on the GPL1 firmware with root.
If stock ROM doesn't fix the issue, then your modem is probably fired like camparks said.

It seems strange that everything was working ok until i installed Advanced signal status app.. and i think even after uninstalling it , it changes those settings permanently. Anyway ill try it thanks
Okay i tried to flash stock rom and now i am getting repeating ufortunately app has stopped for many apps which makes the phone unusable , i forgot what i used to do for this error some weeks ago when i flashed it for the first time..
Edit: nvm , its fixed with a factory reset/wipe
ok i did flash it with stock rom, results are signal is really low, 1-2 lines and some random times 3 and after refreshing apn settings internet isnt working, so.. it does seem like the modem is fried. It shows E or H+ but it isnt really working.
Bottom line, it does seem to be fried.
P.S. Out of curiosity , i dont know if its worth to do but i found an S4 I9500 motherboard on ebay around 20 eur. You think it will be compatible ? framewise and all the other parts..

Redmi Note 3 Pro Network Issue

I've been using RN3 and testing several roms and kernels since the release. As it being my primary device, I'm facing some network issues with the phone. The mobile network connectivity is very flawed and unstable since a month. I'm attaching a link of video of exact problem faced by me(Keep staring at the network icon in notification panel when I started the youtube video). The network abrupts suddenly and then comes back making it unstable, this whole thing happens a lot while internet usage. This makes my gaming experience dull (while playing PUBG and Mobile Legends)
Here are the measures that I've taken till now:
1.) Tried several roms such as Pixel Experience 9.0, Havoc OS 3.1 Android 10, Resurrection Remix .
2.) I got my network cable replaced from a local phone repairing shop.
3.) I tried to toggle through many network types in Engineering mode.
4.) The sim card I'm currently using is Airtel India so Volte support isn't there on RN3. Tried turning off the Volte option.
Current ROM and Kernel: Havoc OS 3.1 Jan 2020 Security Patch and Elindir Kernel V2 60Hz oc.
Any suggestion would be appreciated. Thank you.

Jio network is very poor at my place so I switched to Airtel. This problem arised before a month or so. Before that everything was fine.
P.S. Airtel is the fastest 4G network in India

If Both jio and airtel network is poor then its phone issue. Did u change the charging board? The one which comes with microusb port.
Original board is HMFS. Check if its HMFS or CTFS ?
CHECK those spring antenna contacts are properly connected inside board.

Yes I got the charging board changed nearly before a month and I believe the problem arised since then.
Now I don't know how to distinguish between a HMFS or CTFS, Would you please tell me the exact difference so that I can identify and get it replaced?

Hello guys
My problem is a bit different
I have a jio sim in slot 1, and the problem is that I can't call a few jio users(only a few), some I can call but some I can't
Incoming from that no. Is perfect
But I don't know what is the problem
Is it hardware issue or software or something else
Pls help me
Solution [Fix]
This is how I managed to fix the issue-
I did not change any hardware. I simply installed Network Signal Guru and locked LTE Band 40 while being on the LTE/CDMA/WCDMA in Engineering mode. I used it for 3-4 days and slowly I started to notice smoother connection experience. Finally, I stopped using the app and I'm back to normal and stable Airtel 4G connection.
Thanks @Black_Stark for helping with this thread .
