Need Help! Data Won't Connect - Samsung Galaxy A8+ (2018) Questions & Answers

I just finished doing the guide on unlocking the bootloader and rooting my phone and flashed the latest full stock fw of my country. Here's the problem, my phone is having a hard time and is taking too long to connect to my data, I have charged my sim but still not receiving any data from the sim to my phone. What do I do? Please help.

P970 can't use any SIM cards

My Optimus Black was working fine for about 3 months. Not sure what happened, but it started showing no network/signal. It's a completely unlocked phone. I tried a friend's SIM card and the first time it wouldn't work, but I tried again a few days later and it worked but had a pretty bad signal. Now it won't work no matter how many times I try. I even bought a new SIM card/number (I live in Asia) and it won't work.
I had Android 2.3 and thought maybe something got corrupted, so I wiped and reinstalled, but same problem. I wiped again and installed Mokee OS, and same issue. (By the way, after using Android 2.3, switching to Mokee is so much nicer, although it's in beta and still has some bugs.)
The 6 gold SIM connectors look fine. I used a SIM app and it recognizes the SIM card and its carrier, so I think the card is being read OK.
I live on a small island, so sending the phone back to LG or taking it back to where I bought it (Bangkok) would be a huge hassle. Does anybody have any ideas on things to try to fix this? I'd really appreciate the help.
Can you return to stock rom (rooted or not, as you want) and then tell me if you see something write in LG lockscreen (I'm thinking about LG Security Error) ?

please look into menu/settings/apout phone/status/imei
it is normal?

The first time i wiped the phone i went back to Android 2.3, but all that the lock screen said was "No service". Usually it says "DTAC" when I have service. Is that what you mean?

I think everything is normal. It has an IMEI number. It is 15 numbers. It also has an IMEI SV number that is 16 numbers.

No if the SIM card isn't used that phrase is normal. I got a problem like you but it was written "LG Security Error" and I had to use Smartflash tool erasing cp and then recover my imei. But it doesn't seems that you have the same problem. "/

Wait...before try a sim without a pin code
If it doesnt works then flash with smartflashtool and recover your imei (threads of how to available)

Thanks. I'm going to try flashing the stock rom. I can't find any good threads about recovering the IMEI. Everything I am finding is about Samsung. Do you have any links you can share?

I flashed the new rom and erased the CP data. still no phone service but i haven't reset the IMEI yet. having trouble with that step. i'm not sure if this is going to work though, my problem seems different. my phone can see my SIM card, but i just don't have any phone service with any SIM card. the sim cards work fine in other phones.
try a sim without pin code
and flashing with smartflashtool (erase entire cp) doesn't works?

i don't think my SIM has a pin code? I'm not sure though? There's only one type of SIM you can get here in Thailand. You buy the SIM from a phone shop or 7-11 and add credits to it. I've never seen any other type of SIM card.
Yep, I used smartflashtool and erased the entire CP (had to enable with Windows Enabler). Now there is no IMEI and still "No service".
Retry or by changing baseband now...there was a tutorial in optimus3D threads i think
Or in this one itself
Change the baseband

No sim card problem

Hi i did a search for the problem but none of the other threads with this title matched my problem.
I'm hoping someone can help i rooted and unlocked the bootloader on my x8 and put on ginger DX about 2 months ago and it's been working great.
just for info I didn't flash any custom kernel
So to my problem i tried to send a text message earlier tonight and i wouldn't send. my phone appeared to have no signal. I moved about in the house trying to get a signal no joy. So i rebooted my phone when it came back on it said there was no sim card!
Thinking something had gone wrong with the rom I tried a full wipe through xrecovery to no avail so i then did a repair with PCC.
However my phone still says No sim card
anyone know of any other steps i can take to fix my phone?
if it's beyond me fixing it I'm with O2 and have insurance will they be able to tell that i rooted and unlocked the bootloader and is that likely to invalidate my insurance??
Thanks in advance

FIX
I had the same problem. did you use this guide HERE?
If not do the whole guide following his instructions.
or
If you did go to the bottom of the first post and look at common issues. One of them is sim is not recognised. All you have to do is use the other unlock tool.
You will have it fixed in no time!
Please thank me if you appreciate my effort to try and fix this problem.

I wasn't trying to re unlock my bootloader i just wanted my sim to be recognised, but if i reunlock it is it likely to be recognised?
I didn't use this guide when i originally unlocked my bootloader i used x8toolbox
Have you tried inserting the sim to other fone and see if it works? or try using different sim and see if the fone recognize it.
Im guessing your sim card was damage.

Just tried that just before i turned the computer on and i was just thinking the same thing then i saw your reply
now just need to unroot the phone and lock the bootloader before i ring O2
Thanks for everyone's replies and i'll try to put my threads in the right forum next time
You did not unlock the bootloader properly. There was a bug. if sim is working before and not working afterward. Baddaman54 is right. you need to follow the guide and troubleshooters notes. Even though this has been solved I will make this post so that if someone comes here with the same problem they can see all solutions.

I didn't follow that guide at all, as posted earlier i used x8toolbox and i ran the s1 tool which seemed to indicate it was unlocked fine
But i did it about 2 months ago. The phone and sim's been ok all this time running GingerDX with stock kernel.
it appears the sim is damaged not sure how it happened though.

Bro u may got the point,just happen too sudden...my phone never drop and never root or install custom FW...
Just hope there is file that can totally recover phone..like repair GDFS/Baseband/Imei...
If u loose your imei then there is nothing u can do unless u have TA backup. Sony Service is the only way, hopefully. U also cannot flash someone elses TA! remeber! It could also be damaged sim slot.

Yes,i totally understand it,now only hope is waiting some repair file release..
Can u not send it to sony repair center? I doubt that there is going to be other solution. Im not sure but TA is heavily secured so the only thing u can do is dump and flash. Correct me if im wrong.

Try flashing this ftf file it only has the baseband in it... Just put the ftf in the firmware folder of flash tool and flash it. You won't loss any data.

I have a very similar problem as the OP.My phone froze,got stuck in a bootloop & even after flashing several Stock ROMS & even restoring my Backup TA I'm getting nowhere.Sometimes I get a Factory Reset Screen on start up which asks me to "WAIT FOR POWER BUTTON" but nothing happens n then the phone reboots.I have almost given up hope & I think I might have bricked my device.Plz Help.
P.S. I have not Unlocked my Bootloader nor installed any custom ROMs on it.Only rooted n installed CWM recovery.
I have heard of this..its your efs File got corrupted...and you can only corrupt it during flashing however that's weird it was corrupted during an official update..I don't think the bootloader was updated on 4.2.2... Never the less if there is not a backup with the signature Intact you have no choice but to send it in....sorry

I wouldn't root the phone if you don't need it. Simply download a stock .ftf file and flash it via flashtool, this will NOT void your warranty
I too got this problem suddenly, did resetting the phone, flashed using flashtool & repaired using Sony PCC but to no avail.
Is it a hardware problem ?

I flashed stock and everything was good, I decided to lock the bootloader as I wanted OTA updates. After I locked the bootloader I noticed my Wi-Fi wouldn't turn on. After half an hour of searching and replying to posts I was told to re-flash the whole stock FTF and wipe everything and it worked!

didntask you to unlock tho,

if it is caused by unlocking bootloader, most likely TA backup will solve the problem?

For 2 days I flashed at least 5-6 ftf & 1 kitkat firmware; still my wifi & bluetooth refused to switch on. I think my phone's problem probably is hardware. It's presently in service centre. Awaiting a call from them.

Xperia Z restarts

Hi my friends.
Today was very bad day for me. First my bird died, then my phone stops working and i stuck in elevator. I need your help. Afternoon i want to call my buddy for lunch. Everything starts after lockscreen. When i call him phone wont connect to operator then it says no connection and stuck at dialer. I push power button to get lockscreen and it frozen for while then it locks and i opened lockscreen. When i saw launcher phone resets and every time it resets at SONY logo. I flashed my device 3 times or more. I used .233 . 230 and 4.3 . Every time battery shows wrong percentage. Phone opens when i plugged to charge. But if it has sim card it resets. When i disconnect from charger it resets. I try to open USB DEBUGING for install recovery to reset battery info but when i check USB debuging it resets again. You guys have any idea for that problem.
Did you try clean installation?

Looks like the is some issue with Sim assembly or can be a software/hardware issue.
As all methods have not worked take the phone to a service center and get it diagnosed
ive got the reboot problem too,
try to use philz touch, go to mount and storage, mount system, factory reset,
go back to mount, mount system, flash rom
keep stamina mode off, so far that has kept my rom stable ( tried to turn stamina mode on and caused a reboot after an hour or so)
im not sure if this a final solution, but its what i am trying
Yesterday i got my device from service. They change full body. I didnt understand what problem couses it. Now everything works fine.
