Bricked G950F with Empty efs folder - Samsung Galaxy S8 Questions and Answers

Hi guys, a few months ago I tried to install a custom rom (LightRom) and I was stupid enough to not backup my EFS folder. It stuffed up my Sim card so I tried using a tutorial which said to flash a file called fix.regalstreak. After flashing this my phone was hard Bricked and after flashing TWRP, my phones EFS was empty and no ADB command could fix it. I still am unable to boot into any ROM or stock - even though I can get into the custom Roms install page and my EFS folder is empty with no backup so how do I fix this?
Note:
When flashing stock firmware, if I try to use a pit file with combination of AP, BL, CP, CSC it fails, but if I flash AP, BL or CP it works so CSC has an Issue I think.
However, when I flash with no pit file my phone gets stuck at the Samsung Galaxy S8 screen.
Sorry for the long post

I had the same problem but I managed to solve it by downloading the file: https://www.mediafire.com/file/z0z69kilpala6tu/EFS-SM-G950F-31-08-2018_03-48-37.tar/file after opening in odin put the device in download mode, use odin 3.11.1 open the file in the AP tab then press start, after the procedure, install twrp and install a custom rom I recommend the hades rom 2.0, the stock rom doesn't work the only problem and the device has a null imei

Thank you so much I have been searching for answers everywhere and you have saved my phone

Bootloop while flashing JW4

Hey, I tried flashing JW4 stock rom via ODIN which I downloaded from sammobile.
The name of the file is I9000XXJW4_I9000OXAJW4_XEU.zip and on extracting there were 2 files called JW4_JW4_JW4.tar & SS_DL.dll. I selected the tar file in PDA and flashed. The process passed but am stuck with bootloop. Plz help
I also flashed a jw4. But that was without the dll.
Anyway, after i flashed and it booted up i got a doozen errors telling me it couldnt mount different partitions.
So i gave it up as a bad one and found a thread here at xda with different stock roms and ended up with jw5.
No complications whatsoever. Yet
just google for "stock roms i9000 xda" and you should stumble over the thread i believe.
Good luck

I faced exactly the same problem: bootloop after flashing XXJW4 and many mount errors in the screen. I concluded that this firmware is not standalone in the sense that you cannot flash and repartition the device using it. Following this logic I performed these steps, leading me to a successfully recovered and fully functional XXJW4 phone:
Flash it with a full stock firmware, e.g. XXJVU (mark "repartition" as well).
Flash XXJW4 as you have done it, but make sure "Repartition" is not selected. That is, just select the tar file in the PDA field and leave the rest with the default options.
Another huge problem Got Black Screen Of Death. Am able to get my phone on to download mode but odin is not detecting my phone. HELP ME What to do?

Use another USB port. You can flash deodex version of JW4 which doesn't have any problems
bootloops
Factory Reset / Cache Wipe /
use by the Pitfile from JW 1 and flash the JW 4 ,that`s it !!
LG.G.

Your PDA file might be missing the dbdata.rfs file, see here: http://forum.xda-developers.com/showthread.php?p=24182099&highlight=dbdata#post24182099, which can cause boot loops.

I Just Cant do anything to my Note 3 n900w8, WHY?

let me start by saying I've read almost all your threads only reason im actually bothering is because I'm really feeling like smashing my phone to bits .... that's how frustrating this has been. my phone was rooted and custom ROM till about 4 weeks ago, when Tmobile told me the IMEI on my phone was reported as stolen ... i grabbed my box as my phone i have since it was new and compared the IMEI ... to my surprise IMEI on box and on Phone chasis was not same as the one inside phone .... my phone was unblocked by a local unblocking service here in PR so i went to them and surely they took my phone and lent me another one while it was getting fixed ... "IMEI" was being changed again and it wasn't the one on the box either ... the gave me lame excuse about my IMEI .... they kept my note 3 for a week almost 2 after i got it back my note 3 said it was rooted but i couldn't use any apps for rooted phones as it would say i didn't have root access ... as i no longer trust these people i went on and tried fixing the issue myself ... and here's the thing i have tried absolutely everything cf auto root tar from download mode and even thru odin all versions of odin and using the sm-n900w8 cf auto root and the right roms "different one's to see if it was the rom's or the phone" i am about to give up i simply cannot root my phone so that i can install a modified rom ... thought of contacting you guys ... as my last resort ... i am so sorry to bother i know you guys are very busy ... but if you guys cant help i will have to settle for just a regular note 3 and that sucks... i have picture of absolutely everything i have tried and the outcome and the errors i have gotten and all in pics if needed...
Please pardon me for asking for a little help i really thought i could done this i guess i am not as savvy as i have thought...
Thanx in advanced Emilio Pinella
Does the IMEI on the box match the IMEI on the label attached to the battery compartment?
Have you tried using Odin to get back to a completely stock ROM, flash TWRP, and flash supersu from TWRP?
Ok here we go ...
Yes IMEI on box and phone chasis are same ... the different one is when you press *#06# ...
Secondly i have tried usin odin but absolutely all the files i downloaded are in .zip and odin does not recognize any of them i tried to convert from zip to .tar but it crashes odin thats why i have tried it from recovery mode ... even CF auto flash for sm-n900w8 doesnt work odin does recognize phone so it isnt a driver issue ... maybe if i had apropiate files in right format i could try flashing from odin ... but i dont and i cant find the files in .tar which is what odin recognizes ... as i said i have really tried almost everything ... i have been wondering can it be possible these people lock my phone in a way i could not do anything? ... will wait for your replay ... my phone sucks @The Moment i havent downloaded anything as i am factory resseting everytime i try a new method ... just fyi i do activate devops and usb debug after each wipe ...
Use 7zip or WinRAR to extract the zip from sammobile.com. Once unzipped, it should give you a tar. md5 file.
hello again...
well i was certain of my answer but before i started writing i had doubts so i went and open all the files i have for flashing with odin ... and yes none of my .zip files have any .tar files in them , i have no clue why they are zip files if they are intended for use with odin ... so i went to sammobile.com and yes i had downloaded the 3 files pertaining to my cel phone and tried flashing the stock rom but none of them worked ... some just werent recognized and some gave me whole file signature error or signature failed error ...
i have Tesla-hlte-5.1.1.High_Voltage.2.1-Release-20150824 and its a zip and has no .tar, inside also have cm-12.1-20150423-UNOFFICIAL-temasek-hlte-V10.4 and also no .tar inside and its in .zip format, also have X-Note_Build_15_ND5_Public and yes its a zip and no tar inside...
SM-N900W8-4.4.2-(KOT49H.N900W8UBUCNI1) is my original ROM and it does not have .tar inside ....
something they all do have in common is they have an img file inside that cannot be open ...
and i downloaded files for twrp but jajaja also in zip and no tar inside , just an image file wich is not recognized by odin and not recognized by recovery mode either as i have tried putting all these files in my sd card and have tried doing from recovery ending with results of .... whole file signature failed and signature failed error and also wrong footer error i have pic of all this ... would you want me to send them to you i wouldnt mind... btw thx for your time i really apreciate it.
If the files came from sammobile.com, they are defnintely tar. md5 files.
How many times are you unzipping the file from sammobile.com? The original file from sammobile.com should only be unzipped once.
Well after last replay i went and downloaded all 4 available files for my note 3 from the one dating at 2013 to the one with 5.0 lolli i will do this again tonight and will post the results ... i am certain they will be the same as last time but can you please remind me of steps to take using odin and which odin should i use as i have a few versions .
Once again thx for your time .
I like Odin 3.07 which is what I always use.
If you use Odin 3.07, put the phone into download mode, open Odin 3.07, place the tar.md5 file in the PDA box, uncheck everything except f.reset time, connect phone to computer, flash, when you see the word "RESET" in the status window, remove USB cable, remove battery, replace battery, use button to boot into recovery, perform a factory reset, wipe cache, reboot.
Ok
I will do this from home as soon as i get there and i will post results any specific one you would want me to start with?
Start with a rom that matches the bootloader currently on the phone.
Ok
Hmmm is bootloader the number after model example UBUCNC1?
Yeah just checked and bootloader would be for my current 4.4.2 N900W8UBUCNC1 .... Also says that latest firmware is one of the firmware i downloaded the one containing lolli 5.0
So you downloaded the cnc1 from sammobile.com and there is no tar.md5 file after unzipping?
Just got home
I got home im unzipping and i will let you know in about 2 minytes if there are tar.md5 inside what i downloaded ...
Ok so far so good
All have .tar.md5 in them so i will try flashing with same rom version i have 4.4.2 to see if then i can root and flash a cutom rom ... tell you in a few minutes how it went... wish me luck.
ok finished
i finally got to flaSH WITH odin and now my phone is 5.0 lolli ... can you guide me on how to flash root with odin as cf auto root does not work i took picture of what it did when i tried to auto root tell me where to send it .... or can you tell me where or who might have tesla 5.1.1 high voltage rom or X-note in .tar.md5 format ...
once again thanks for your time and understanding all i need now is to be able to root it so that i may install custom rom after i actually find them in .tar.md5 format.
Find twrp here
http://forum.xda-developers.com/showthread.php?t=2494245
Get the latest 2.8.7 or any 2.x.x 4.4 .tar.
Then get SuperSu flashable. You can google that.
Flash twrp with odin.
Flash SuperSU.zip with twrp.
It's rooted.
If you want to flash a custom rom just flash the rom of your choice in twrp. No need to root first.
Sent from my SM-G925F
Root is not required if you want to install a custom ROM, just install a custom recovery. I recommend flashing TWRP.
Find TWRP for your device from here (make sure you download the tar version of TWRP): http://teamw.in/Devices/
Supersu 2.46 is here: https://download.chainfire.eu/696/SuperSU Download and save Supersu to either the internal or external memory. If you put supersu on an external memory card, power off the phone and put the card into the phone.
Boot the phone into download mode.
Open Odin and uncheck everything except f.reset time.
Click on PDA/AP button and put TWRP into the box.
Connect the phone and flash TWRP in Odin.
When you see the word "RESET" in the status window, remove the USB cable, remove battery, replace battery, boot into recovery, flash Supersu, and reboot.
Ok will do now and tell you if anything ... but i read somewhere this version of android is unflashable ... but i will try what you are saying .
Which version of Android is not flashable?
Ok i gotta say if it wasnt for you i would still be stuck ... fortunetly i am riding 5.0 lolli and my phone is now officially rooted all i need to do is get tesla's 5.1.1 high voltage on it and i will be good ... so basically just need tesla in .tar.md5 to be good ... all thx to you .
Where can i download it or now that i have twrp as my recovery can you guide me thru on that? ... thx again.

Paying to get this fixed

My s7 edge got stuck at boot screen so i reflashed stock rom and rerooted then restored the backup i had, it said fail because of low memory while restoring the system and now when i try to reflash the stock rom on odin it says model dismatch fail.
If someone could help me fix this I'm willing to pay something decent, but not a whole lot lol
Re-download the stock rom and flash it

i did that lol thats when it says "model dismatch fail"
Do you have custom recovery?
Do you have a custom recovery?
Do you have the right and the newest Odin Version?
Did you try it with another transfercable or USB-Port?
Do you have the newest samsung drivers?
Did you have any Odin problems like this before?
My suggestion:
Just do a full wipe on your phone. Downlad the newest Odin Version. Get your device into download mode (maybe try different transfercables or USB Ports and the newest samsung drivers) and see if it works now.
If yes, flash the right Bootloader and Modem for your device and then flash the rom you wanted to flash.
If this didnt work, (and you have a custom recovery) try to reinstall the rom without any backups via the recovery at first and check afterwards, if the device is now recognized by Odin.
Good luck

I guess you still have twrp installed.
1. Step: go to TWRP and wipe everything except your SD-Card
2. Step: enter download mode on your device and then plug your usb in (maybe try a different usb-port or even another computer, or another usb cable)
3. Step:Flash the newest bootloader & modem in one step.
4. Step: Enter TWRP again and flash the firmware.zip via the installation process
I dont have TWRP, but i got it fixed, somehow my roomate got it, thanks anyways guys
So all he got was my phone to turn on, im still having this model dismatch fail issue..
Maybe You're trying to flash wrong firmware? What model did You buy?(check box) and what firmware did You download?
If nothing works then download 7zip. And remove all files from that tar.md5 file and leave system.img only. And then try reflashing it.
This way no matter what device You connect it should force flash this image file. Although it might be dangerous (a tiny little bit) so first make sure that You have proper firmware for Your model.

Yes, I've used these files multiple times before i did what i did, ill give that a try, if it works, i owe you.
If system.img by itself will flash successfully and Your phone won't boot then add slowly more files to that tar file (boot.img, recovery.img etc)
You could also try looking for a pit file for Your phone and then flash it with it. Pit file usually fixes most problems even broken partitions.
And make sure that You put that tar file in AP/PDA.
If nothing above works then send me screenshots of ODIN and the file that You're trying to flash. Maybe I'll notice something. But I hope You'll fix it

[SOLVED] IMEI lost after flashing a rom

Hello,
Today I tried to flash KING OF NOUGAT v13 but my phone got stacked on Samsung Logo(+30min). I was forced to restart it(Power+Volume Up) and flash the recovery that made before flashing. To my surprise when the phone boot there was no connection(only Wi-FI). As far as I can see IMEI, Bluetooth and Mac address are unavailable. I tried different backup(I have two on SD card) but the problem was the same.
When I created the backup I made a full backup including EFC, but for some reason, it's not working.
I also tried this article , and put those commands in the terminal but no result.
I know there is an option to fix it if I flash the stock rom . But i would like to know if there is another options

SM-G935F Firmware for United States

Hello, I purchase a SM-G935F from a pawnshop today that was flashed with a custom ROM however it does not boot. The phone goes into download mode just fine and want to flash stock firmware but cannot find the USA version. The box came the phone and appears to be a USA version, the UPC code on the box is 8806088275123 and I check the IMEI on a website service and it came back with this model number SM-G935FZKLTTT and says it was sold in the USA. Any help from members would be greatly appreciated, thank you in advance for your help.

I forgot to tell you that factory reset is required when switching from custom rom to stock rom so make sure you flash the non home CSC file and not the home_csc file.

Yes, it is in the download. When you download Samsung firmware from Sammobile or Updato website they come in a zipped file. You'll need to extract the zipped folder which will give you multiple files labelled AP, BL, CP, CSC and lastly HOME_CSC.
This is an example of what the files look like when the files are extracted from the downloaded firmware zip file:
http://prntscr.com/k07am0
The non_home csc file is used to tell the phone to wipe the user data on the phone when flashed, the home CSC is used if you don't want to wipe the user data on the phone when flashing firmware.

Hello again Benjamen50, it failed on the first try, do I need to check re-partition? or Nand Erase? What about a Pit file? sorry to keep bothering you but I appreciate your help.

If you are flashing Oreo firmware which is 8.0 you need to use Odin 3.13 or newer as the older Odin software does not support flashing Oreo firmware.
The only buttons you need to click are BL, AP, CP, CSC then start and nothing else.
The default check boxes under options tab will be auto reboot and f reset time. Others should be left untouched and not checked.
You'll need to reboot download mode again which can be done by holding the download mode keys until you get that blue screen again or that it says that something ran into a problem with the blue screen which allows flashing as well.

Hello again, well I thought it worked because I got a PASS in Odin however, when the phone boots, I get a Black screen saying Samsung Galaxy S7 Edge then it goes to a blue screen with the android logo and it says erasing at the bottom for a few seconds then the screen goes black. The phone still goes into download mode however, it will not go into recover mode. Before flashing this I could get into recovery mode but would see a custom page with loading and rebooting options. Am I missing the stock boot loader? So sorry to keep bothering you about this.

try using octoplus samsung tool if you dont know how look it up on youtube first best of luck to you
