S8 does not recognize any sim after hard reset - Samsung Galaxy S8 Questions and Answers

Hello all.
Basically title. I have tried every possible reset after this and nothing helped. I have tried putting another sim (thats working for sure) in and still nothing.
This thread is basically my last resort before trying to flash another ROM(currently using stock 9 android) and see if it persists.
Any help is much appreciated

I have the same problem, imei and baseband are unknown after factory reset, flashed multiple firmwares but still no luck.
Can you see your imei number in settings or by dialing *#06# ?

gt-i5801 no sim

iv tried 3 different roms now and evrytime after the boot the os comes on ok but there is no sim showing i have tried different sims but still no joy what am i doing wrong ?
check if ur IMEI is showing the correct or not.
I also have same problem, the IMEI number is still present
Try this:
1. Have you tried manually searching your network and then registering it?
2. Try the stock firmware.
3. Try removing the IMEI, and them re-adding it.

I had exactly the same issue with a samsung 15800. I tried everything but in the end, I found out the phone was faulty. If youve rooted it, reinstall stock fw and take it back to the shop. Samsung will exchange it. Just make sure you install the proper fw on it. Samsung exchanged my 15800 for a brand new one btw
swap Kernels
how about this... Flash another Kernel. Like if you have fugumod..then try G3Mod.
My experience.. when i flashed Kyrillos 7.0 which has fugumod by default, i do not get any network...no matter what I try.
So I flashed G3 Mod kernel and things were fine.
Try it. Else your phone is just faulty.

[Q] Booting stuck at "X" logo.

Today i noticed that my nexus lost gsm signal. Yestarday it was ok and i didnt change anything. So, I turned it off and then on, but it stuck. There is only nexus logo and nothing happens. I had stock android 4.3 with bootloader locked and stock recovery. I tried unlocking bootloader, flasing twrp and wipeing cache/dalvik/data but it didnt help. I even tried flashing PA, but it also stuck on boot logo. After that i tired full factory reset (system and recover) using WugFresh's toolkit, but it also didnt help. In stock recovery there is a red triangle with dead android. Do you have any idea what may be wrong?

You can try this one: Unbrick [bootloop] NEXUS 4 and flash Official 4.3 image [the easyest way]
I have already tried it, it didnt help. But i also tried 4.2.2 and it started after like 5 mins. It takes some time but it boots. But still, there is no gsm connection. I tried flashing diffrent radio but it didnt help. In settings/info there is unknown baseband and no imei. Is this possible that some hardware that is resposible for gsm is damaged?
Check your APN settings b

I bet it's not a problem with apn. When i try to search for gsm network there is an error.
Booting phone takes more than 5 minutes. It shouldnt happen on fresh system.
What is more, info in settings says that there is unknown baseband and unknown imei.

Log above is done without sim card, but it doesnt work even if sim card is inside.
This lane is important I think:
Code:
SCREEN_STATE error: com.android.internal.telephony.CommandException: RADIO_NOT_AVAILABLE
I would try a full factory image restore with data wipe. That might help. If not... May be RMA time. Remember to use fastboot!

Hi I just met the exactly the same problem you described: woke up and found no signal there, and after a bunch of flash things I noticed that the IMEI is gone. All these happened in 1 week after I actually received the phone.
BTW, can you use WIFI and Bluetooth now? Mine is still OK, only IMEI shows 'unknown'.
Hope someone could come up with a solution.

I didnt check bluetooth, but wifi works fine. Your problem looks same as mine. It happened 2 weeks after I recieved my nexus.

I have already done full factory image restore. The problem is that there is no RMA in my country, the phone was imported from UK.

I recently faced this problem -- booted into recovery and flashed android 4.2.3, still had the issue. did a factory reset which actually wiped nada on the sdcard and as golden after that, re-rerooted and all.

If your imei is wiped you are screwed. The network won't allow you to use it. Your phone is illegal without an IMEI no. I got a Chinese one that had no number

No SIM - Insert Sim card

hey guys,
I have just gotten my phone back from repair. It was getting the cracked lCD replaced.
So i went and put my SIM card into the SIM slot then i rebooted my phone, just to see a "No SIM" message which then proceeded to say "Insert SIM card". My wifi and everything is working and i can make emergency calls. I have previously had problems with my EFS folder and a corrupt IMEI but i fixed that issue and i don't believe that these two incidents are related whatsoever.
This is the thread with all of the information of my last problem. http://forum.xda-developers.com/galaxy-s5/help/service-t2898890
To try and solve this new problem, i have done the following:
1. Taken the sim card out and restarted phone and entered the sim card back in numerous times in various different sequences.
2. Done a full factory reset, reflashed a new rom, modem and bootloader.
3. Restored the EFS folder.
4. Tried a different SIM card.
This could be a hardware issue, but i feel as though it is software related, but i am no genius so i am open to any suggestions as to what it may be and how i may be able to fix it. If i am not able to fix it i will just send it back to the phone repairers and see what they can do to resolve the problem, but that would be the last thing i want to do.
thanks for any help.
not to worry. I have now solved the problem and everything is working perfectly.

i was on android 4.4.2 thouchwiz, i then upgraded to android 5, which also meant i had to upgrade the modem, which seemed to fix the problem. I then downgraded back down to android 4.4.2 touchwiz and that solved the problem.
so maybe you could try upgrading your modem or something? let me know if that works.

By modem do you mean radio?
It's an unrooted phone in my case, unfortunately.
the modem is a file or software i guess you could say in which controls the the signal on your phone.
hmmmm, im not sure what you could do then... im guessing you do not plan on rooting either?

Hi bro first of all thanks for helping me out here but i tried to download a firmware from the site you gave me & its downloading at 15kbps!! It will take too much time to download...
is there any other source i can download it?
+ can you please explain what will be different from the stock 4.3 rom i installed?
Thanks again for helping out, Much appreciated!!
You should flash the latest 5.01 rom, not 4.3.
Try searching for the rom on updato.com.

didnt work unfortunately
i installed this rom : http://updato.com./firmware-archive-select-model?record=BF01B00E1F3711E6949E0CC47A44B7B2 (im from israel)
and i get the same exact problem
also im not 100% sure but i remember i checked the efs folder and it was empty...
am i f***ed or is there still hope?
i have the imei number on the sticker under the battery btw if that helps
Did you flash anything else that could have caused the loss of imei?
The imei should be able to be injected by a cell repair shop via jtag.

No network access (Moto G5 Plus)

Hi everyone,
I've been having a problem since yesterday morning. Everything seemed to be fine with my phone before I flashed a custom rom. I was using at the moment MSM Xtended and I flashed the latest version of CrDroid. After flashing that other custom rom and booting, my phone had no network signal. All it reads on the status bar after that is just "No service". Of course, I removed the SIM card and reinserted it many times but that did nothing.
I've already tried flashing another rom (the latest AICP rom) and even going back to the one I was using at the beginning, but still nothing. I even tried reflashing the NON-HLOS.bin file and erasing modemst1 and modemst2, but it didn't do anything either. I also tried flashing this deodexed stock rom and booting. Interestingly, that kind of fixed the problem, since it recovered its network functionality. However, after reflashing an Oreo custom rom, it loses it again (actually, I've done that a few times today, but the last time I tried flashing the stock rom, for some reason it didn't fix it anymore). I don't know if in this case it's worth mentioning it, but I've tried checking my IMEI on both, custom roms and stock rom, and it's never been 0 at any moment.
TL;DR: My phone lost its network signal after flashing a new custom rom and I have no idea why. If anyone could somehow help me, I'd be really, really grateful.
I have had this happen so many times it is not crazy LOL. The best you can do is find a rom that it happens the least. For me it has been AOSP extended. Signal has been great. It is a bug that I dont think the devs even thought would happen with 8.1 roms. It will happen to everyone at some point if we stay on these 8.1 roms i guess until we get a workable 8.1 stock rom. There will be those who chime in saying it nevver happen to them but it will eventually.
Well, it's nice to know I'm not actually the only one then, I guess. But is there nothing I can do? Since I can't seem to get it fixed even by flashing the stock ROM anymore and flashing AOSP extended didn't seem to help at all either
I know brother there is no rhyme or reason it just happens. I am hoping when 8.1 stock comes out for us there will be a new batch of 8.1 custom roms without this problem. Right now i am on extended and havent had any signal problems for a few weeks so who knows.

Okay. Luckily enough, Oreo stock ROM doesn't look like it's gonna take too much more to arrive... Or so I hope, at least. Thanks
I was using LinageOs and it was working great. Then I decided to install DolbyAtmos and for that I flashed Magisk . Suddenly i had no network but my sim cards were detected , IMEI was there but no network on either sim whatsoever. I tried reflashing the LinageOs and PixelExperience ROM but none worked. So I tried flashing(ADB) the stock firmware only to lose my IMEI . After reading this post I tried Debloated ROM and my network was back. I should have stopped at that point but I tried to return back to stock again and lost IMEI again and now I have tried Dbloated,LineageOs , PixelExperience , AOSP Extended , but none helped me getting back network . Now I am stuck with this phone with no network , I had a backupp of my system before I flashed Oreo ROMs (with EFS) so I can get IMEI back but no network. This phone was my daily driver and now I have no idea what to do.

Everything you said is exactly as if I had written it. I did all of that and now I'm exactly in the same position. No idea how to fix it yet. Still, if you managed to find a solution somehow, please write a reply on this thread again

No success yet , but read on some posts that different baseband could be an issue.
Solution I've tried and worked 100 %
Hi bodies,
You can turn off your phone,
Go to fastboot menu by pressing and holding power button and volume down button in the same time.
Roll to "Restart Bootloader" with volume up/down and validate with power button.
Now select start and the network is back.
see you !:fingers-crossed:
