[Q] Randomly "Mobile network not available"on my S7500L after root - Samsung Galaxy Ace Plus S7500

Hi I just rooted my Galaxy Ace Plus GT-S7500L today, and everything was working amazing!
Suddenly, about 4 hours later I tried to call somebody and I got surprised with the message on screen saying "Mobile network not available".
I turned off the phone and turned on back.
This solved the problem for the moment and I was able calling.
This is the first time that happens to me with that phone, and I think it is a big coincidence, that it happened the same day I rooted the phone.
Do you think if that problem is related to rooting the phone?
How to fix it?
Maybe that won't happen again, but I want to be prepared to fix it if that happens, or maybe if someone knows to fix it, I will do it to prevent that happens again.
Thanks!

Nexus 5 WiFi problem

Hi guys, I am having a strange problem with my nexus 5, or I should say my Wife's Nexus 5. Right what is happening is that when my wife's phone is connected to a WiFi network it does not receive calls. My phone is identical and has no problems at all. The phone has been back to where we bought it from for repair twice and they finally gave us a brand new phone. After getting home and restoring my wife's phone it has the same problem. Both phones are stock and updated to 4.4.4 . I have checked the settings and as far as I can see they are identical. If I reboot the phone it will ring with WiFi on but after a couple of minutes the problem returns.
Now I would guess that an app is causing the problem but I have tried uninstalling and re installing most of her apps but still can't solve this. I have spent ages on the phone to our provider (T-Mobile UK) tried my sim in her phone but still have the same problem. Is there any type of diagnostic software or app I can run to try and pin point the problem?
The phone has been factory reset but still got the same problem! Bearing in mind the phone is brand new and has the same problem as the old one its got to be an app hasn't it, but how to work out which one
Thanks in advance

Well after an evening of uninstalling and re-installing apps and resetting it seems to have cured itself. I am sure it was something to do with the recent system update, as the problem only started recently. The phone is just over 6 months old and we have had no problems until this. Still fingers crossed it seems ok now.

Hi, i'm having the same problem!! When on wifi sometimes calls get through but most of the time it blocks them, I also thought it had to be something about an app but i even booted the phone into safemode which disables all 3rd party apps and the issue was still there. Where you being able to narrow it down to something in particular??
EDIT: Nevermind, i think i found a thread with the solution.

I should have updated ages ago, the problem was in fact being caused by the sim card. Dont know why it suddenly started playing up but it coincided with the software update to 4.4.4 But my phone was identical and had no problem and my wifes did. Compared to hers my sim was relatively new we eventually ordered a replacement sim and there has been no problem since
Sorry I could not be any more help

[Q]How to Fix Dropped Calls On OnePlus One?

Calls drop often. Usually within the first minute, and then every time when Im calling back after 10sec. The phone itself does not lose signal. Strange thing is, if I'm getting phone call after first/second drop, phone continues connection without problems... But Only when Im receiving a phone call not when Im trying to re-call someone.
- I tried replacing my sim and the issue persists. No problems with other phones using this Sim (even in the same locations).
These are pretty annoying issues. Anybody else experiencing them? Is there a different radio I can try for the phone? Is there any log I can access showing a reason for the call drop, or any trouble shooting I can do? This seems to be independent of WCDMA Only/Preferred/GSM/WCDMA (Auto) settings. Or if, how to change these settings?
Note: This has nothing to do with the network. I've been with the same company (Orange Europe) for about 2.5 years, and have never had this happen before. This has been consistent since I got my OnePlus (about 1 week ago)
That's true. I'm experiencing this as well for quite some time now. At first I joked and said: Hey, the NSA joined our conversation.....again. But after some time it really annoys me. This has nothing to do with the ROM or kernel as I have tried out various combinations. What I found out is that it got better after I returned to stock CM 11s with stock kernel. But it's not gone completly.
Honestly I neither know how to fix it nor what is causing the problem. Try to reflash the CM11S 25R firmware and see if it gets better. I think something is wrong with the modem software since CM11S 22R,25R and CM11 builds are using the same modem software. Maybe the announced update for the end of this month or early next month will fix this. I really hope so because a phone which is not able to hold a call, can't be considered as a real phone.
Oh im pitty You, If You'll get something just please let me know. Any advices or help will be appreciated. Maybe waiting for new CM relase will solve the problem, I do rly like this OS even with so many bugs... there is always an option. Move to stock 4.4 published by OP on official website.
Anyone else facing the same issue? Was there ever a fix for this issue? I'm on 38R and still encountering this issue
Same here.
See this thread for answers and work around. No solution as of yet.

Factory reset the device. If that doesn't help, your device is probably faulty and you should return it.

You should try a hard reset and never turn wifi on. I have random reboots and freezes too (even with wifi off) and that solved to me.

with wifi turned off same problem nothing happened, phone rebbots during searching the web, during talking, same sh*t,
after hard reset during changing language it reboots 2 times, so with my ugly phone there is no problem with wifi but its a problem with cpu or ram vs rom.

Are you on the latest firmware for your region? What about cell signal? Did you install any apps after reset? I'm still trying to figure this phone out... I've been with Samsung 4ever and really want this phone to work right! But might have to cut my losses and go back to my S5

I don't think it's a Wi-Fi issues becuz I am facing the same exact problem, and I'm getting a replacement device too. Becuz it happens even when Wi-Fi is turned off. I think it has to do with the phone can't handle heavy loads when it's doing alot of multitasking the ram management is horrible real bad.

Yea it's just Samsung fault that's all. The only reason I am returning mines though is becuz I rooted it and tripped Knox and now they have came out with a method to root without tripping Knox lol so I am going to get a different one with Knox back to 0x0 but as for the random reboots only Samsung can fix that issue with a software update and don't hold your beath. Because only some devices are getting update which is so stupid.

Please help me with my problem..

Hello all,
Im asking for your help and advice since i looked and searched the problem and didnt find any solution and hope you guys will be able to help..
To make Long story short i updated the other day to the latest jgcaap linos 23rd..
Idk if thats connected but for some unknown reason my phone started to loose cellular internet and got wacky like loosing signal, resetting the network signal, etc.. finally resulting in restarts and bootloops every 5 or 10 minutes.. and when i took out my sim card the opo works ok.. can it be only a faulty SIM or maybe more of significant hardware related? And also how can i get more information on why causing the bootloops and fix the issue?
Sorry for the long message but please help me if you can..
Best Regards,
Ofer Becher

No sim error and no wifi

Hi, for some reason my wife's U11 just decided to stop working - but only the sim and wifi. The no sim message shows and wifi won't turn on. I've reset network settings and have gone as far as a complete factory reset to no avail. It seems to me to be a hardware issue, so I'd like to know if there is anything else I might be able to try? I'm out of ideas, and if it truly is a hardware fault, then that kinda sucks, but oh well. It was a nice phone while it lasted...
I should add that bluetooth still works.

This is starting to get interesting. If you have any updates, please let us know.
I've managed to downgrade it now to Android 8.0. Same issue.
I don't want to believe that this is a hardware fault. But it really seems to be...
Maybe its the antenna? I don't know. MAybe I'm going to root it and flash a custom rom and Wifi repair app.
But It really think there's an hardware defect for now..

That's super interesting to me. Do you know when it happened to you? It really feels quite coincidental to have this happen to a few people.
It happened just 2-3 month ago. First I wasn't able to turn the phone on cause of the WLAN issue. Cause my phone space was locked I wasn't able to authorize myself cause of the disabled connection. After a few tries I put my Sim card inside the phone, and it connected and I could authorize and disable this memory lock. But afterwards it never worked again with my sim card. It seems like it wouldn't even recognize my Sim Card. No Pin question or symbol at the upper front of the display. Nothing. It's really werid and annoying, that something like this happens. I can't believe that it's hardware related.. How would it be possilbe that it's hardawrare related and whe have suddenly the same problems nearly the same time...
I should note that my wife has had her screen replaced before (she dropped the phone and it basically cracked all over). Have you replaced yours?
Yes I replaced mine too. But nevermind I had that issues before. My phone ran all well with cracked screen and one day I had that issues... So I changed my screen in the hope it would fix it.

I'm wondering if it will be a more widespread problem. I'm going to try and get in touch with HTC and see what they have to say. Will update if I hear back from them.
Okay, that would be great. But I don't have high expectations that they'll answer. Due to the fact that they have stopped there smartphone section for now and no more official updates and stuff like that.
But let's hope die at least...
I have exactly the same issue. It happened yesterday. It was just there, sitting on my desk, one minute it was working and I was checking my e-mail, the next one it was not. The phone now detects no SIM card and if I try to enable wi-fi it just hangs in "enabling" status for some time until it gives up and disables it again. I am not 100% sure, but I think I also had a short time in which wifi was no longer working and the SIM connection still was, I remember seeing the 4G logo and maybe I even browsed the internet for a short while. By the way, I have not replaced my screen. Now I know that I can probably spare myself the hassle of doing a hard reset.
It is really suspicious that this weird problem is happening to several people within a short time frame. It would be cool to hear if HTC has anything to say, but I am also not expecting anything from them now, especially for a phone which is out of warranty.
In case it can help, as the author reported, bluetooth still works and it is possible to connect the phone to the internet using bluetooth tethering on another phone (the good old M8 helped here ). This doesn't solve the issue, but is much better than nothing, most apps will work and it is easier to make a controlled migration to another phone.
Any news here?
Same issue here!!! Help!!!

Same issue here!!! Help!!!
I have the same issue with a U11+ bought in Germany (I know, other model but hey). I have tried using the other sim slot and using another (definitely working) sim. WiFi doesn't work either. My phone has no visible damage (not even scratches) and no parts were replaced. I can't remember it ever getting wet either. For me it stopped working on 2. of September.
Sorry guys. HTC were really slack at getting back to me, and unfortunately they want me to send the phone in to get it inspected. I know it's out of warranty and since my wife is well and truly into her Huawei P30, this phone is unfortunately going to just have to remain this way. Sorry for not having any better info.
The same issue I am facing now. No SIM CARD Detected and WiFi isn't connecting.
What things I have tried doing so far?
1.) Factory Reset - 3 times.
2.) TWRP Based RUU Restores ( 2 possible versions tried )
3.) Tried Restoring zip based restore
4.) Did a Full Internal + External SD Card Wipe and then flashed RUU.
5.) Restored stock ROM.
Nothing is working at all.
Now, Trying to do S-OFF but as the phone itself is not booting into a normal OS, I cannot install Sunshine app and proceed. Help needed, at least in getting the OS to work.
Thank You.

It seems there's no way without replacing hardware to fix it. But if we don't know what causes this error we cannot proceed.
I tried the same things as you did. Also unlocked bootloader. My device is starting but I cannot proceed to the main menue cause of no internet connection. I'd love to try a custom rom. That's the only thing missing.
Also if the phone is rooted there are WIFI Error fixing apps and check.
I have bought myself a OnePlus 7T pro MClaren edition and I'm really happy with it. But also I don't want to accept that the htc just died from nothing.
Same issue here, happend a few months ago and after a week the phone started working. Now again no SIM detected and wifi won't connect.
