Samsung S8+ HK Snapdragon Radio problem - Samsung Galaxy S8+ Questions & Answers

Hi guys, i have a question. Recently i got weird problem, my sim card stopped working overnight, Everything is normal, there is info about simcard, number, imei, everything, i tryed changig sim, but all sims that i tryed act the same. Things that i find that are wrong. In siminfo Radio is off, and airplane mode icon is always on, even if i turn it off in settings icon is still blue, i tryed flashing lates rom over odin, and it didnt work, i also tryed flashing custom rom (one that i found that is not on some wier chinese site that ask for my chinese number), twrp and still nothing, i lost a few days, and i need some help, i tryed everything i know. I cant go and enter *#*#4636#*#* to see siminfo and turn radio on(something that i saw on YouTube), that code dosent work on my device. I even tryed dissasembly the phone to see if everything is conected, and i dont find anything unusual, everything is in place. So please if anyone can help me that would be grat.
Im sorry im not native English speaker, and i apologize for my bad writing

Looks like a damaged efs partition

Well, it may be, but i have EFS backup when was okay(i learned thats important, hard way on s4 ), but everyting seems okay, i finally find right combination rom, and sim card seems to work fine, i cant call to conform, but its on 4g connection, and signal strenght is changigng just fine. And as soon as i flash stock rom radio goes off.

I actualy solved my problem, i flashed combination rom and tur radio on, right after that i flashed stock rom without CSC, and it worked, i got error on decryption, but i just wipe/factory restart from recovery, and it worked. So if anyone have some problem with ther S8+ g9550 PM me, ill try to help out.

http://wiki.xda-developers.com/index.php?pagename=Kaiser_ROMs
Go to the Comm Manager and make sure the Phone is turned On and Flight Mode is OFF
This has happened to me with a few ROMS.
wish it was that easy but no
When i bought my tytn 2 i had same problem .
try to go in SETTING/PERSONAL/PHONE
then select tags BAND in the bottom of screen.
Usually you'll find :
Select your network type = Auto
Select your GSM/UTMS band = Auto
Try to force this parameters according your mobile company .
then make a Network selection manually .
I hope this help you.
Ciao

tried that 2 nothing
The only other thing that helped when this happened to me was to flash the Original Shipped ROM.
i hate myself should of left your first one alone.... flash that old one and still the same..phones still not working
But even in a manual search didn't show any phone company?
I have the same signal problem here. I trying to get a AT&T Tilt to work here in Brazil. Tried all available ROMs and Radios. Tried every available configuration stteing on the phone (band, connection etc). Flashed the phone back to the original ROM(adn Rdaio) and NOTHING.
I still waiting a miracle from heaven!

I resolved on mine (tim) with follow:
try to go in SETTING/PERSONAL/PHONE
then select tags BAND in the bottom of screen.
Usually you'll find :
Select your network type = Auto
Select your GSM/UTMS band = Auto

You have a BAAAAAAAAD ROM flash....
Take a deep breath and relax. I suggest hard reset first then remove your SIM card and re-insert. make sure the cut out edge of the SIM is the out side not on the inserted side.
Make sure you have a ROM, and i would suggest one that does NOT have the radio cooked with it. It can be Dutty's or Sleuth. I recommend Sleuth's ROM for I find it more robust. Flash properly and you will have your phone back.
BTW... remove your SD ( Memory Card ) before you start the flash.
Good luck.

[Q] I5800 doesn't recognize Sim card after flashing.

Hi guys,
I've come across a rare problem, I can't find other people having the same problem with the same device.
I flashed my 1yo GT-I5800 from 2.1 to FROYO, I5800XXJPF version.
I tried the guide here on xda, but that provides me 'one package' files and my phone wouldn't come further as the 'samsung' screen. After a lot of research I found a person with the same problem and the problem basically was that when using 'one package files', you apparently flash your bootloader too. So I searched for a firmware version with separate files, flashed first back to the original version (so that my phone would have the original bootloader) and then flashed, without the bootloader to a stable version.
Everything works like a charm, I'm very happy with it, but I have big issue... the most crucial part of the phone is not working, namely the sim card. My phone doesn't complain about it at all, had no errors, only the notification that I can only make emergency calls.
My question is: what should I do to fix this? I'm pretty sure it's not hardware related, since other sim cards don't work as well and mine works on other phones. Some people had the same problem, but this was because their phone booted in airplane mode.
tl;dr
I flashed my phone 2.1 to 2.2, the sim card slot doesn't work anymore, software related.
I'm really looking out for any answers, thanks in advance!
PS: Since I cannot move threads, I made a copy of this one earlier on another forum here around. Since this is also a good section for my question, I posted here the same thread, since in the other section people don't(/can't?) answer my question.

Flash the XXJPU latest firmware as it is a lot smoother, faster and less buggy (if it has any bugs at all).
Now, as to your question, i think it may be due to you not having any signal. Check that your phone is not in airplane mode and also go outside or somewhere you have good signal. Another suggestion would be to call up your sim card provider and ask if they are facing any technical difficulties.
@Smonic
Okay, I'll try that version. To your solution: my phone just doesn't see the sim card, not even my contacts. It is not in airplane mode, I checked this already and mentioned that in my post.
Thanks for your respond, but unfortunately it didn't solved my question yet. I'll update you if the new firmware worked if I find it.
Update about firmware: Found the I5800 firmware you posted half a month ago, flashed to that version but it didn't solve the problem. He recognizes my sd card when I put that in, but still not my sim card.
Any ideas?
Now I faceing the same problem... Did you find solution?
I see its quite so probably you could solve a problem... I hope Im wrong.
Some problem help please.........
Keep rebooting the phone
Mine Bcame ok after 4-5 reboots(sometimes becomes ok in 2,and sometimes works flawlessly)
Man i m lucky

[Q] Huawei ideos x5 (U8800) APN settings wont save, NEED HELP ASAP

Hi everyone! I am posting this here because I need 10 post to post in the right tread...
So my problem is this: I installed the aurora 4.0.3 custom rom that seems to work great but I cant connect to the internet... (wlan works great)
I had before this oxygen custom ROM wich worked good but decided to try android 4. when I installed the newest official update...(i think it was 2.3.5 or something like that, looked newer that 2.3 almost like 4.0)... the internet did not work at that point eather (after the install) The apn settings wont SAVE!!
They just dissapear after I press save when everything is correctly written! well I tought that installing the custom rom would fix it... well it didnt...
I installed everything correctly, recoveries, deleted stuff from recovery etc.
One thing I tought that will changing a new SIM card fix this?
IDK what to do now, please help me!!
Oh my operator is Saunalahti from Finland (im there too...)
EDIT: I tried with my brothers sim card wich has a different operator, dna and the internet worked fine. there was also all the apn settings, dna internet and mms. switched back to mine and still not working. could the SIM card get any damage while installing new firmwares and custom roms? I had mine in the phone under the installs if it matters.
Anyone? and if you thinky I write bad and messy, I am not so great at english but I hope you understand : )
Noone knows on this site how to get my apn settings to work???
btw they worked today for like 5 mins then I rebooted and they where gone again...

Phone has no radio/baseband, help please

Somehow I ****ed up and now my phone cannot receive cellular signal at all. In about phone, IEMI number is unknown and in SIM card info, everything is unknown. What I did was this.
1. Flash CSC Selector on my existing ROM selecting ATT CSC. Everything was fine (aside from no voice/wi-fi calling)
2. Wanted to update to latest stock PDA/radio/bootloader so I did (through Odin.) Everything still good.
THIS IS WHERE **** HIT THE FAN
3. Flashed TWRP.
4. Formated data, flashed CSC selector selecting ATT, flashed Makisk, flash Makisk-PHH rot.
After that, no cellular signal at all.
Can someone help please? I really need this phone for work and if I can't get it working tonight, I'm going to have to go to AT&T store and ask for the cheapest phone they got until I can get this fixed...
BTW I already tried re-flashing everything to stock through Odin and it did not help.

Follow the instructions. Faced the same problem took hours to figure the **** out.

Overwhelmingly confused, touch input inverted, USSD codes not working, even on stock

Soooooo..... Here I am again with a friend's s6. he wanted a custom rom, and knox was already tripped so why not.
flashed twrp in odin, flashed frankenstein rom, everything was normal, rebooted, touch inverted. I remembered I had this problem a few years back and eventually fixed it, found two of my old threads and tried some of the stuff the threads talked about, like dialing *#2663# to update the touch panel firmware.
well I tried it again and got an error, something like could not find, invalid mmi. I searched google and xda some more and found advice to go back to stock, so I dl RWC firmware (I'm pretty sure, otherwise its on XEF or XAF multi csc for some reason) from samfirm and flash with odin. I reboot to a bajillion FC, more research, factory reset, ok it works now, go to phone app, USSD code still not found :S
I am so confused by all these variants, and CSC codes, and strange behaviours, and also dl mode + odin, adb+fastboot in bootloader any day ahaha.
G920W8 rogers. Please help. I just want to help my friend and ive been on this now for too many hours, thanks
EDIT: oh, it worked on stock this time... okay nevermind, but before I apologize and shamefully ask a mod to close this thread, if I try flashing the frankenstein nougat rom again and the touch axis gets inverted, is there some other way to get the correct touch panel firmware if the USSD code doesnt work in that rom? (I tried samsung info, no go)
