Lot of problems with N910F - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello all
I have somes problems with my Galaxy note 4 n910f
1st problem : i flashed last stock rom by odin , all success , but at start "install DRK FIRST"
OK... I reset phone, it start, without DRK
I check IMEI, serial number, all fine, it connect to mobile data , can speak at phone, send sms..
So my EFS Look like good
2nd problem : lags, and freez 2 or 3 seconds, every time...
3st problem : all time it disconnect of wifi i have to re type password, tryed delete file of password, he re created one, but problem still
This phone was rooted on previous rom, with philz touch recovery
For trying to solve wifi problem was downgraded to android 5, but same problems, so i came back to 6.0.1
I rooted again to check if lags and wifi problems still here after, and of course they still here...
So now, what can i do for fix it? Install custom rom like lineage rom?
Repair kernel with Z3X box? ( i think buy one)
Some people says motherboard is dying
Thanks for yours answers

Maybe its sd card related? Remove it and see if that helps or not

[Q] Help - No sim card error

Hello,
i have got a S4 which has been rooted and flashed. It worked fine for a while but now every now and then i get a error message saying there is no sim card in it. When i reboot the phone it works normal again, without touching the sim or opening it.
I have cleaned sim card and contacts but that did not help.
Any ideas what else to try?
TIA

Hi ,
SIM card problems if they are not hardware related , they are usually caused by IMEI ( efs folder) or wrong modem if you have and efs folder backup , restore it.
What S4 you have , what rom do you have , what modem do you have??
When it fails to recognize the sim card check your IMEI dial *#06#
Hello,
i have tried everything i can think of without any success. It is a Samsung Gt-I9505.
The problem with checking IMEI when it does not recognize the SIM card is that i can't do anything but restart it. There is a error message with restart as the only option.
Now it is doing it as soon as it starts up. I never have to remove the SIM card so the phone recognizes it, just a simple restart without touching the SIM is enough.
I am on the last official Australian ROM. Baseband I9505XXUGNH6, Hernel 3.4.0-2309103 Build number KOT49H.I9505XXUGNH6
I have tried it with another SIM and same thing happens so it is not because of the SIM card.
Any ideas what else to try? I do not have any back ups of anything.

Hi mate,
Your case is not clear , it does not look like firmware but i would not discard that possibility , do you have stock or custom rom? try to reflash
Also there is a chance for what you tell me that the sim caddy may be defective

I am on official ROM, flashed over ODIN. You recommended to check the IMEI when this happens but i can't because the only option is to restart the phone.

Please more details
When you have the no sim errors it does not allow you to dial *#06# ? why does the phone freeze ?

No, it does not freeze but a pop up shows with only one option "restart". I tried to touch the screen, home or return button but nothing works but touching the restart button.

I see, is strange if you said that whith a reboot works fine it make me think more in a hardware issue...maybe the sim caddy..
This phone is driving me crazy. The replacement SIM reader arrived today and i replaced it. Now it does not find any SIM, just getting NO SIM error as soon as it starts up. I tried putting back in the old reader but the same happens.
Anyone any idea what to do or just recycle the damn phone?
Come on guys there must be someone with an idea

Samsung Galaxy S4 I9500 - NO SIGNAL (IMEI/IMEISV:null/null;Baseband Version:Unknown)

Hello everyone,
As this is my first thread, and I have been reading previous assists based on IMEI fixing and couldn't find the answer I am looking for, I really hope that the XDA community can help me fix my Galaxy S4 I9500. I will try to explain the problem the best I can, and I will create a list of every solution I have tried in the 3 week phone fixing saga I have.
1. The problem :
My friend decided he does not need this phone anymore, everything was fine with it except the battery was swollen(but I bought a new one so it doesn't matter). The day before he gave it to me, he accidentaly dropped it in the toilet and it couldn't boot. I opened the phone, cleaned it with alchohol and the phone booted up normally. The thing I noticed was that in the status bar the network symbol was replaced with No signal symbol. I tried 3 SIM cards and none worked. I decided to downgrade to 4.4.2 KitKat version and this is where everything went even worse. I used Odin to downgrade a firmware downloaded from sammobile.com, but I didn't create an /efs backup because I have flashed an Alcatel Idol 2 before and there were no problems with the IMEI or so. It turns out that Samsung devices are different and I am left with NO EFS BACKUP. I know, I should have checked what to do before flashing the device, but what's done is done. The device is doing everything great, there are no problems with Wi-Fi or Bluetooth either, except I cant connect to a network because IMEI is null/null and the Baseband is unknown. The thing is, I am not sure if the IMEI is wiped completely because of a hardware problem, or it's software related because of the /efs folder, because I am not a developer, but a civil engineer...
2. Solutions I've tried so far :
- Flashed many different Android versions;
- Flashed a Lollypop with adonis.pit with Re-partition checked on Odin;
- Tried writing an IMEI and repairing the EFS with Octoplus box;
- Tried flashing an EFS backup from my friend's Galaxy S4 I9500 ( IT IS ILLEGAL IN MANY COUNTRIES, NOT IN MINE, BUT I WANTED TO TRY AND CHANGE THE IMEI LATER SO IT WOULD NOT BE A PROBLEM );
- Tried flashing with a IMEI_null_fix.tar.md5 file which i found on a forum and that didn't fix it either;
- Tried KIES to return the stock ROM but either it does not recognize my device, or it says that my device could not be initialized or so;
- Took the phone to service, but in my town the only service we have is not very professional and they didn't even know the IMEI null does not mean that I will have no wireless connection/bluetooth connection, so they didn't fix it either;
- Tried with EFS Pro, Terminal Emulator and programs similar to those, 3rd party and PlayStore ones;
- Maybe other things but I could not remember because I think I tried everything...
I don't know if the problem can be fixed, but deep inside me I hope that there is a solution, and I think this is the best place to search for help, because it is a great phone and I don't want to throw it away just like that.
Thanks in advance everyone, hope you can come up with a solution.

Boot your phone in TWRP. format everything (I would recommend you to even format your internal storage).
Then flash the full package of latest H2OS. Then u have 2 options
1. Stay happy with H2OS as now, your IMEIs would be back and phone would be usable. however there may be frequent network drops (as seen in most cases).
OR
2. Format data/cache/dalvik and system ang flash CM14.1 (Official/ Unofficial any would do; latest version preferred ). U will get IMEIs working but phone may have random Reboots (as seen in most cases).

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.

Maybe your SIM card connector is damaged.
did you put in already a other card or put your main card into another phone.

(SIM 1)
I tried another sims but still nothing, and these aren't broken or something, tho I'm seeing that Miui 12 has already the problem about non detecting SIM, Soo.. I'll try Fastboot ROM Miui 11 Android 9
Okay, i solved it, tho im a newbie, there was some videos about how to fix it, the first step is flash the stock rom / not the miui 12 one for me, it has problems with detecting chips in some telecom companies like Claro or Telcel, wich mine was Telcel, so i flashed the fastboot rom ( miui 11 android 9) , and at this point, it wasnt detecting the chip still, but somehow i could recieve calls and everything, but now being in miui 11, the 2nd step is restore de cqn file, im not gonna post it but ill give the video where i got it, but with the programs and all that, you can restore de qcn file via diag, thats all, there some videos about how to pass to miui 12 without these problems but idk, heres the videos
stock rom via fastboot
restore cqn file( no sim detected)
that was all, see ya
