(HELP PLEASE) Galaxy S6 died overnight and now in a boot loop

last night i went to sleep with m galaxy s6 g920f STOCK 5.1.1 had a fair amount of battery left in t. When a woke up in the morning my phone was dead i thought the battery would have been consumed . I plugged it in charged it . Now when i try to turn it on it just jo to "samsung Galxy s6" logo ,screen becomes a bit yellowish and the phone restarts same thing is happening again and again.
Now i have tried to reinstall to odin, then going into recovery factory reset cache but same results. anyone please help this phone was running stock os so... i have searchd the web but there are no ways to fix it ...
Regards
any help please !
guys i need your help please
I would suggest you download a ROM from Sammmobile that corresponds to your country and install that via ODIN and if that doesn't work try one from a different country or one tha is unknown (I.E. that doesn't belong to a any country), I softbricked my phone trying to install H3G for UK and for what ever reason it would not install. However...
I downloaded one called BTU and that worked using this app SamFirm. To get my version I installed type the Model number SM-G920F and Region BTU to download, once it has downloaded then decrypt the file by clicking the Decrypt button and unzip the decrypted file and then use ODIN to install that one. Using the SamFirm app downlaods it faster and gets the latest from Samsung as far as I am concerned. Good Luck.

The only thing I can think of is trying one from your country and trying any other one. You can use the SamFirm software to download different versions, else I think your phone is broken for some unknown reason and you will have to get it fixed under the warranty. Or install the Samsung Smart Switch from samsung and get the firmware installed that way via the Emergency Software and recovery mode, but it will wipe everything and do a factory reset. Also you will need the serial number and model number of your phone.

I have really made a mess trying to fix it myself.
I will write the current status and at the bottom what I've tried so you can skip

now the sim card works in other phones and when I remove it the device registers it is SIM CARD REMOVED but when I put it back in nothing happpens, and mobile networks settings is gone
*I started in stock 5.1.1 (MADE NANDROID BACKUP OF EVERYTHING INCLUDING EFS) and flashed twrp via odin > (everything still working)
*flashed XtreStoLite 2.4 (5.1.1) via twrp > (everything still working)
after several months
*flashed new 6.0.1 bootloader and modem via odin and tried to flash XtreStoLite 3.0 (6.0.1) via twrp > got stuck in bootloop...
*used smart switch to go back to stock 6.0.1> Everthing was OK until about a month later the phone suddenly restarted and doesn't recognize the sim card
* I tried factory reset
* I tried samsung but they gave it back saying I've tripped my knox flag
*I flashed 6.0.1 XtreStoLite bootloader, modem and TWRP again via odin
*I flashed XteStoLite 3.3.1 (6.0.1)
*I tried restoring from the first nandroid (stock 5.1.1 from the begining) and got stuck in bootloop again.
*reflashed XtreStoLite 3.3.1 (6.0.1) and tried restoring only the efs. still doesn't work.

I saw some threads talking about octoplus box but I still have my efs Backed up my and SN and IMEI still show up.
Please help me I am here I am willing to learn and search online. I've tried everything i've found online.
Hi.
Try to use Smart Switch > Software Update and Initialization to recover your firmware, hopefully you get your network back.
Tell me what happens, gl.
Sent from my SM-G920F using XDA-Developers mobile app
almost same thing on a long thread here, no solution so far:
http://forum.xda-developers.com/galaxy-s6/help/g920f-network-issues-t3291903
I am seriously considering it could be sim reader issue, or some cold solder somwhere on mbo.
My IMEI was also showing in settigs, but when dialed *#0011#, in stack 1, there was "IMEI NG", after write cert operation via octoplus, it says IMEI OK now, but NO SIM, and no mobile networks menu still.
Same like you SIM is detected when inserted or removed, and phone offers restart to access mobile networks, but after restart nothing changes, KNOX tripped by previous owner, phone was in three 3rd party repair shops, where they made even bigger mess than it was, when I brought it to them.
i had the same issue when i upgraded to mm so i sent to shop they had to downgrade it to 5.1.1 and use octobox to fix it
Thanks for replying Legend.
But even though I did the software Initialization in smart switch once before it is not working for me now.
I've tried twenty time while reinstalling and restarting the pc I even tried a different pc I get the same error message every time. "failed to run firmware upgrade unknown error occurred".
any other thing to try?
you could try to restore that backup you have, from when everything worked and then flash 5.1.1. bootloader and modem for that csc via odin before rebooting
According to Smart Switch with your sn it is ILO so you need 5.1.1 bootloader and modem from ILO 4 file fw package.
*I just managed to flash stock 6.0.1 via odin (even though It failed at hidden.img... it boots normally) still no sim card tough.
*I realized that maybe all of this happened because when I flashed stock via smart switch for the first time I didn't have my original s/n so I put one from the internet and it wasn't my region.
meaning I flashed stock of UK and it still worked for a month or so, so that's weird...
*Thank you brenner that is a good idea and I will try now
question how do I extract the bootloader and modem out of the fw? I just open the tar archive and take the boot.img and modem.bin files and flash them as is?
nvm found a guide

There are .tar-s which are single file, and 4 files, the ones with 4 files has separate bl/modem
btw, isnt sn written on back of the phone, along with IMEI?
OK, I've flashed the nandroid stock 5.1.1 (LMY47X.G920FXXU3COJ1) and its bootloader and modem from sammobile.. still doesn't work!!
How can this be? everthing is EXACTLY the way it was when it was working!
and no, my model at least doesn't have the S/N and IMEI written at the back, and I didn't keep the box
any other suggestion anyone?
*also there are so many post in subject if I ever find a solution I will make a guide.
-bump-
still no solution..
I've flashed back to current stock ILO...
Meanwhile looking for a lab with octoplus box, still would love solving this at home
At home or not, I would like to solve it too
Bought a second hand S6 the other day and was working perfectly fine until I carried out the update. Now on 6.0.1 and am getting the exact same problem, my SIM works in every other phone. Has anyone found a solution for this?
Not that I know of, except hw replacement, which cost as a used phone with 1+ years of warranty (6 months warranty on motherboard after replacement, on motherboard only)
But I am willing to donate to whoever finds a solution for it.
No i think your problem is a S/W problem, i have 2 G920F with this problem, one of them is 3 binary and another is 4 binary FW, now i work on it if i can solve this problem i told you here.

[Completed] Correct Imei - no network available [GT-N7100]

Hi im new in this forum, I tried to search extensively in this forum and some people have similar issues like me.
I have a Samsung Galaxy note 2 GT-N7100.
When I received this phone was in 4.3 jelly bean and i made a successful upgrade to 4.4.2 kit kat, and I don't remember well why, but I needed to get back to 4.3 and the process corrupted my imei to generic one.
I tried everything to fix it like changing modems, flashing another roms and nothing works, so... a few weeks I contact a Poland guy who fixes my corrupted imei remotely and everything was fine, my original imei back.
Now I have my imei, but same issue, No network registered, I have signal network, also my sim is recognised (virgin mobile) and I was researching here about that, but nothing works...
My phone is not reported or something like that, so I don't know what can I do now
I don't know what any info you guys need to help me
Today i'm testing with stock firmware 4.3 (i'm from Chile) and trying the N7100UBUEMK4 ROM, flashed "Patched_N7100_MK4_KERNEL" and "Patched_N7100_XXUEMJ5_Modem" trying to fix this issue, but nothing change. Also, this solution kills my wifi, so I'm discarding this option for now
Sorry for my english and thanks for your time
PS: I need to add some information, but i don't know if is relevant, when I go to the network configuration to add "manually" a network show me three different companies (Movistar, Entel and Claro) (and I'm Virgin mobile) "Movistar" seems to be "unlocked" but it fails when It try it "Cannot connect now try later". Claro and Entel immediatly fail

Greetings and welcome to assist. I think the issue maybe related to downgrading, have you tired using kies emergency firmware recovery ? That should put the phone back to its original state
Good Luck

Hi, and thanks for welcoming!.
I was trying right now but Kies doesn't recognising my N7100, but Odin did it, is there a pre requirement for kies?
If I don't open Odin, kies does nothing, but If I open Odin first, and then Kies... Says "Connecting" and after a time said: "Device not responding"
I did not know about Kies emergency firmware recovery so I was following some tutorial, and it said I must be in Download mode, etc.
Anyway, I think my device is "clean" at the moment, after flashing 4.3 stock from odin, I didn't root or flashed custom recovery at the moment

Do you have the drivers installed ? You can try smart switch as well as kies and just select emergency firmware then follow the instructions. There is always mskips tookit as well, he has a thread in the n2 forums plus skipsoft.net
Good Luck

Drivers okey, I tried Smart Switch and recognize my N7100 but can not use the emergency firmware recovery, says I can not initialize.
And I can not download mskip's toolkit right now, the server is down apparently: crying:
If toolkit fails do I have a chance with another solution? I'm running out of ideas on how to fix this
Thanks for your time
EDIT: skipsoft is back, I'm gonna try it now
EDIT2: Okey, I'm kinda lost right now, with this tool (mskip toolkit) it looks amazing, a lot of options, but I don't find nothing that can help me with my issue, about flashing stock firmwares I assume I must download them first, but I really tested a lot of roms (stock and custom) and I don't know how to identify the real problem, if is a modem problem, or just the sim doesn't works in this device

[HELP] Missing IMEI and Baseband on a Network Locked SM-S337TL

Hello guys,
I have been stuck in this for about a week now. Have read tons and gone through a bunch of videos but still stuck. I will greatly appreciate any help.
I was trying to unlock a Samsung Galaxy J3 Luna Pro SM-S337TL (GP) Tracfone.
Downloaded and flashed the combination file using odin but after booting into the binary it show:
CP Crash
Upload Mode
Secure NV read decrypt fail.
Because of this I am unable to complete the network unlock. After several trials I flashed the 4files and got back into the phone, to discover the IMEI and Baseband are gone.
I have tried to download and flash many versions of the Stock ROM for model and even used KIES to find the corresponding Firmware version using the Serial number, but I can't seem to get them back.
I didn't backup before I started. Big MISTAKE.
How do I fix the device to be be unlocked and get the IMEI and Baseband back? One step at a time please.
