No signal [FIXED] - Samsung Galaxy S8 Questions and Answers

The problem got fixed a year ago.
The problem was the hardware and not the software
I've replaced the corrupt phone.

how you changed csc as u explained? usually flashing a diferent firmware with another csc will completly wipe the phone a d restore efs info, be sure ur flashing a different csc not included in the original csc pack (oxm and btu r the same csc for example).

Ive flashed my csc to israel celcom(CEL) with RICE Tweaks from my rom and then back to unbranded israel(ILO) with csc selection, didnt helped.
When the problem started to appear it crashed for a couple of minute(no signal) and then came back, now it doesnt works at all

maybe thats the problem, ILO and CEL r both the same CSC (OXM), if you dont flash other CSC it will not completly wipe the efs carpet, try downloading BVO from sammobile and flash it.
before flashing twrp or anyyhing first try your signal with completly stock BVO.

is wifi working ok?
had problems with my first s8 regarding gsm/wifi signal, got it exchanged to get it to work(it was stock untouched)

I will try this out, even though i did deleted the efs folder using odin(Checkbox EFS Clear) and even nand erase all.
Pretty sure it wont work cuz i live in israel, but i will try anyway.

after a full clean flash of the official firmware go to factory reset from the phone settings, if that doesnt work im out of ideas, but after a clean flash, do all the process without the sim card and put it after the factory reset

After a minute without doing anything suddenly, my signal is back but it crashes every time i use it like to answer a call, i guess my antenna is defect, i will return my phone for a replacement.

Hi, have you been able to solve the problem? It happens exactly the same

Yes i have a similar problem, apps crash, phone lags all the time. I use 2 bluetooth devices connected all the time, location is always open, nfc is disabled, i use nova launcher prime. Phone is not rooted. Call drops when there is no reason. Cellular signals complete goes away even though it was at full service a moment ago, then after 10-15 seconds, it comes back again. This phone is making me really sick. I was using galaxy s5 before this and it had a better performance than this one. I have galaxy s8 g950f by the way.

Worse and worse modems?

Hi guys,
I was wondering if you encounter the same problems like I do.
Long story short(er):
I own a I9505, with an LTE contract. Over time, and especially once moving to KK, the stability of LTE connection got worse and worse. And there are two problems: instead LTE I have EDGE or worse connection most of the time (the area where I work should have very good network coverage) AND even if appears as connected, internet is not working.
I have tried several (the most important ROMs), the problem is the same. I have tried with the recommended modems (at the moment of install). Finally, I have even switched back to the original ROM for my country. I can say that this was the worse experience of all, basically could not connect to LTE.
So, anyone encountered the same issues?

I feel the same.
I recently flashed the NZ stock firmware via Odin and the NC6 modem that comes with it is terrible!!
I now regularly lose signal and data.

As a mention, this is due to the fact that before the current custom ROM I have installed the official firmware for my country.

The normal is that u flash the ROM at the country of ur phone. No of ur country. You have remains of older firmwares there. Is normal that ur phone will be crazy.
1. Make a backup of ur Internal Memory
2. Make a factory reset (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Conect it to Kies 3
4. Kies 3 will give u the info you need for know ur correct CSC. This will be btw parenthesis close CSC.
5. Knowing ur CSC, take a look for this firmware in Sammobile.com
6. Download and flash it with ODIN (Dont flash a "Black EDITION" if ur phone isnt it)
7. Dial *#1234# again and take a look if u have the same what Sammobile was telling you. If not, flash again the firmware. (Example in pic attached)

Thanks!
Will try that once I get home. As I knew that Black and normal edition only differ on the look... the official one that I flashed was indeed the Black.
All you say makes perfectly sense...

It worked. Up to a point.
I have installed the official firmware and it looked like it was supposed to.
But, as I installed the custom ROM, both CP and CSC file have been modified/changed. So incompatibility still there.
More findings:
if I go in the service menu with *#2263#, if I chose 3G, there is no connection to the network (strange, as I am in the middle of the city, bu tnot unusual). but if I connect to LTE, i cannot make calls anymore. If I choose the mix 3G/LTE, once the LTE signal is lost, it gets back very slow, even if I am back in a zone where there definitely is signal. Basically, if I am on the stairs ro underground parking, lte is lost, 2g is on, and I don't get back lte once I am in the office (or on the street). i MIGHT get it when I change cells....but not a rule.

Note 3 no baseband, no sim reading, camera force close

Hi All,
I just bought a second hand note 3 of ebay. The seller told me there where some problems with the sim slot. It was not reading any sim.
No problems there just buy a new sim slot and solder of the old one. Except when i turned on the phone i see there is no Imei, no baseband, camera foces closes, other apps also force close. And telefoon reboots now and then out of the blue.
So first diagnostic, no sim problem but a software problem. I browsed the forums here and tryed the bootfix methode, the clean rom inc pit. The remove efs folder by hand methode among others.
Al keep getting the same results. Now i have the 4.4 bootloader and clean rom phn for netherlands. But no imei and no baseband.
Anyone got any idear on how to proceed? I offcourse dont have the Original EFS full backup sinds the previouws owner did not know what he was doing.
Look for someone with a SPT box
Your modem didnt flashed - Flash latest modem XXUFNF2

Flash the FIRE script that is located in these forums, it should automatically rebuild your EFS. Then flash your Stock ROM. Should fix it. -- Unless the original owner has really messed up the EFS partition - But the Note 3 has a fallback which by it has an auto-rebuild of the EFS partition when you run the correct command, in this case the FIRE script.
EDIT : Attached it for you..
Will try these tips tonight will keep u all posted.

Sometimes it'll come straight back after the bootloop.fix - other times you need to flash Stock firmware straight after and it'll rebuild itself.

Take the battery out, then place back in, reboot into recovery clear cache and then reboot.
No luck. It gets to the normal samsung logo lighting up and all stays there for over an hour now.

[Q] S4 Problem with network WCDMA (3g)

Hi all, I have a problem with 3g.
I bought s4 i9505 and it was on 4.2, I had problem with slow internet, so I called operator and they told me to turn on WCDMA only in settings..
When i turn WCDMA only on, it loose my network (emergency calls only), and i have no network at all.. when i put wcdma/gsm automaticly it has normal network..
So i thought its problem in firmware, so today i fleshed 4.4.2 with odin.
Now i have same problem, no network with wcdma only..
I serached internet and i tried several programs for 3g, but nothing worked.. any solution ? thx

Some problems can appears:
1. Type *#1234# and paste here what appears. Continue with the step 2 if you have wrong CSC.
2. Wrong CSC. Solution: Install Kies 3 for know ur CSC (pic 1). Go to Sammobile.com and download the correct firmware 4.4.2 (correct region) for your device.
3. Flash again this firmware and let the process finish till the final. Dial again *#1234# and verify if all is correct like the firmware you downloaded and installed before. Flash again same firmware if not.

Might be a corrupted EFS folder.
I have had the same problem for 3 weeks now. I've tried searching for a solution here and in other online sites to no avail. I personally tried flashing a new stock rom, flashed some odd number of modems, tried factory resetting etc. Nothing worked. I'm afraid it might be due to corrupted EFS folder which I still don't know how to repair.

desperately in need of help s4 i337m no sound can't call etc

Hi everyone I've been lurking around the forums the past week trying to find a fix to my problem and I just find anything that will fix it. I'm hoping one of you that has a bit more experience with this can help me.
OK so here's my problem
My Samsung galaxy s4 i337m was rooted but I wanted to unroot to update cause I'm new to it and never used my root for anything
I looked around and downloaded a stock ROM and flashed it in with oden and I had no WiFi no sound couldn't make calls no videos so I tried flashing another custom ROM and it let's me use data and text but no calls no video no sound I usually only get 2-3 hours of down time here to look for a fix and I have been all this week but can't seem to work the problem out
Does anyone know how to fix this so I can call my kids again I'm not gonna be homeor anywhere close to a place to get a new phone for another month
And to sweeten the deal I'll send 25$ PayPal to the person that can get this fixed for me
Thanks for your time

1. It's the correct firmware for your device and the latest. Yes. Problem of sound/wifi are related to wrong baseband normally. Reflashing it 2 times solve the problem.
2. We will try other options.
3. You have to install STOCK ROM for dial *#1234# first.

Odin "Nand Erase All"

If i will nand erase all on my Galaxy S8(SM-G950F), will it delete the download mode?
If i'll do that, can i still just after that install the stock firmware?
Will it delete things that even stock firmware cannot fix?
BTW the phone is OEM Unlocked.
I did use Nand erase all on my s8 and it did not delete the download mode. What problem do you have?

Network is not available
No signal on my phone, did factory reset, twrp advanced wipe everything, reinstalling the stock firmware from smart switch, changed csc and changed back, didnt work.
Check tutorials to fix, from a tutorial:"In the dialer, type- *#197328640# or *#*#197328640#*#*", cant even type that, it will still show me Network is not available.
My IEMI is good, when i type *06# it is working.
Tried my sim card on another phone, it works, on my phone it should show signal even without sim.
Do you know how to fix this?

How does Nand erease work? So odin first erases the nand area, then writes firmware? After that what would happen to IMEI #, won't it erase efs folder?
The issue I have is with Galaxy S8 Active. I bought it a second hand and it was attached to Sprint. That person flashed it and possibly changed CSC to XAA in the phone, but flashing doesn't affect it at all. I have tried flashing T-Mobile or Sprint firmware, but the about phone page still shows XAA/XAA/SPR. There is no unlocked version firmware for this phone and it seems that only 3 carriers had this device (ATT, TMB and SPR) Whe I flash firmware, the progress goes fine and it passes, but all it does is change the build # of the OS.
So I wanted to do nand erase to remove all changes that original owner did, but don't want to destroy the phone.

I've nand erased before a long time ago, it didn't destroyed my phone but I do not remember if it will change the CSC to the firmwares one(Assuming that you use a firmware with the CSC you want).

Actually I do want to become TMB and I did flash the correct firmware for T-Mobile. I think original owner used something such as "Eng boot or factory binary" to go into service menu and change CSC to XAA. There is another interesting thing. When I go to about page, under Service Provider SW it shows G950U, but the rest of the phone is G892U. < I can't get rid of this!
1) Is there a way for me to maybe get Factory binary file which will allow me to change CSC? I did fine combination file, but it was for v2 bootloader, mine is v3 at the moment.
OR
2) Nand erase will do something good and erase the flash memory, unless nand option doesn't erase a specific memory location in the phone responsible for CSC.
Also, how can flashing a phone not do much in terms of really changing something in the firmware? I have not seent this before. I even tried flashing USERDATA file, thinking I would get T-Mobile's bloatware, but it didn't, not even TMB boot logo.
