Please help! I'am using model SM-N900. Today, I wanted to downgrade from my 5.0 custom ROM to stock 4.4.2. I downloaded the 4.4.2 firmware and opened ODIN. I selected AP mode and selected the .tar.md5 file I extracted and it loaded it up. I booted the phone into download mode. I selected auto reboot and F. Reset time. I clicked start and it started. It went along well until it got to system.img in which it stopped and failed. Now I tried a lollipop image, and it came up with the same result. I tried flashing the TWRP image and it flashed successfully. I was able to boot into TWRP and use it. I now tried flashing a custom rom. I tried a AOSP lollipop rom, 5.0 TW rom, and a 4.4.2 TW rom and they all booted to a black screen. I'am now desperate to fix my seemingly bricked device so somebody out there, please help! Thanks in advance.
I also tried flashing a bootloader I found somewhere in XDA for the N900 and I'm still able to flash TWRP and use it and access download mode but it hasn't changed my problem.

What bootloader was you using and what one have you tried to flash
Sent from my SM-N920F using Tapatalk
I'am not sure what bootloader I was trying to use before but I was on a custom lollipop TW rom so maybe its a lollipop bootloader? I flashed the one linked here: http://forum.xda-developers.com/galaxy-note-3/general/safe-to-downgrade-ll-to-kk-sm-n900-t3016966
UPDATE
TWRP factory reset and other wipe functions except cache wip are no longer working the wipe completes with a blue error. Was it because I accidentally checked nand erase all in TWRP?

Iv an idea you flashed wrong bootloader so I would download stock lollipop Rom no root make sure you flash bootloader and modem too so download to your pc and use Odin make sure you haven't enabled reactivation lock

Device has been fixed!!!!
YESSSSSSSS
I downloaded a pit file for my device and used it along with my kitkat firmware. This time, the flash succeeded and my device booted to a message saying data is corrupt. I did a factory reset from recovery and rebooted. The device successfully booted up and now I'm up and running again and downloading all my apps and stuff. No need to swap motherboard!
congratulations mate

What exactly does a pit file do though? When I selected it it selected the re-partition option which everybody says not to use but it was the only way my device is successfully up and running again. Why do you think flashing the .pit file along with my firmware file worked?

basically a pit file increases partition size and as yours had corrupt data the system couldn't read or rite to it so pit file allowed you to install your rom I can't believe you got away with it normally bootloader doesn't forgive but glad you sorted things

Hi guys. I need help on restoring my s4 on complete stock. I messed up real hard
Here my problem. I have an i9505 s4 which is simlocked to globe philppines(mobile carrier). I tried to get rid of its booting animation because it's so annoying for me so I wanted to flash a stock rom of i9505 international version via Odin 3.07 but I rooted it first via Odin also. The time I am flashing GalaxyS4-CWM-6.0.4.4-GT-i9505 tar file, I got a fail in Odin then my S4 won't boot anymore and it says firmware upgrade encountered an issue blah blah kies. I tried to boot to recovery and that's what is also shows up. I tried to use Kies but what it does is just connecting to my device which takes forever. So I flashed a stock rom via Odin and it worked but the very problem is It's very laggy and says that process stopped responding, camera not working, status bar also not working, wifi not working. In short, all core apps are not working or just works for a minute and then stops and hang the phone. Sometimes i get a wallpaper screen(nothing else, just my wallpaper which occurs when it hangs).
Luckily I still haven't hardbricked my phone yet so I need all your help to fix it before I hardbrick it :crying::crying::crying:
Please help me how to restore my S4 to the very stock like fresh android software because I'm trying to still fix it days ago. I WILL TRY TO ANSWER ALL YOUR QUESTIONS REGARDING TO MY PROBLEM JUST PLEASE HELP ME PLEASE ! IM VERY WORRIED
You can chill. Nothing wrong with your phone and you didn't mess up anything. Things like that happen. You cannot brick your phone this way. It's almost impossible to brick it.
1. Perform factory reset in recovery.
That will probably fix it. Report back if it doesn't.
ps do not use CWM because it's outdated. Use TWRP and uncheck auto-reboot before flashing it trough Odin.

Is it okay to flash any build number on my s4? I just downloaded one of them "I9505XXUHOA7_OXAHOA7" and I flashed it on my phone. I tried to factory reset/wipe cache partition/ and wipe dalvik cache in cwm 6.0.4.4 touch but it always hangs and core apps are not responding. Maybe the rom is the problem? I don't know but I'll try to flash twrp and report back if it doesn't work.
I have installed TWRP and its stuck on bootloop. Tried to reset its factory settings but stuck on bootloop then cache partition and dalvik cache. I tried to install the rom via TWRP and it says installation failed. Should I download other rom ?
I just want it to make it work like what an s4 should be. Even on stock or custom rom.

-I tried to flash a stock rom but it always fails even in twrp, so I downloaded a custom rom just to try it to install but It also hangs and core apps are malfunctioning. I think all rom I install fails miserably. I think I messed up real hard because I flashed two pit files in my unit.
-There is no error code in TWRP everytime I fail installing rom. It just says error installing zip.
I really need to restore it to complete stock. Every rom I successfully install hangs and crashes core apps in my unit.
I WILL TRY TO ANSWER ANY MORE QUESTIONS BECAUSE I NEED IT TO USE NOW. PLEASE

No you cannot flash that with TWRP. You cannot flash stock roms with TWRP. You can only flash it with Odin. Besides you need to unpack that .zip file.
Keep in mind that you also cannot flash that package if you were on Lollipop.
Download a rom from here:
http://samsung-updates.com/device/?id=GT-I9505
Take this version: I9505XXUHOJ2
It doesn't matter which one. Then flash it using that guide from the link you gave me.
Wow thank you helped me alot.It worked but I have this little problem. "Unfortunately, google play services has stopped" and same as filter installer, always popping up on my screen and I can't access messaging app because it always crashes next to google play pop up.

Dear xda users,
I have a big problem with my Samsung S7 Edge G935F!
Yesterday my phone restarts continuously so I used Odin to flash Firmware Stock. First, I used this Firmware: http://forum.xda-developers.com/s7-edge/how-to/official-stock-firmware-update-odin-t3335065 .
Odin doesn't show any errors and my phone restarts; but after Samsung S7 Edge Boot Splash Screen, the phone shows a screen with yellow triangle and Android dead and then, phone restarts in Stock Recovery Mode.
In the Recovery mode when I press Reboot System Now or PowerOff, appears "Verifying DMVerity Hash Tree..." and then "Failed" and my phone restarts again in Recovery.
I tried Wipe data and cache but Nothing!
Then I tried to repair firmware with Kies 3: No errors but my phone won't boot!!
And then I tried another firmware file with Odin but nothing!
The phone is Completely Stock! Recovery Mode and Download Mode work and the phone is recognised by PC.
Please help me!
Thanks in advance
Sorry for my english

Have you tried doing a "Factory Data Reset" in stock recovery yet?
If not, do that before doing anything else.
The Factory Data Reset in stock recovery will WIPE your internal
sdcard but it will not wipe your external SD if you have one.
Also it would be very helpful to know the exact filename(s) of the
stock firmware(s) which you have tried to odin flash and what the
model of your phone is. (G938F) or other variant?)
Good luck and have a great day!

Thanks for your reply!
Yes I tried Wiped data/Factory Reset and Wipe cache partition in Stock Recovery..
Device: Samsung Galaxy S7 Edge
Model: SM-G935F
Firmwares tha I tried to flash with Odin:
Netherlands (Android 6.0.1) G935FXXU1APF2_G935FPHN1APE2_G935FXXU1APEQ_PHN
Italy (Android 6.0.1) G935FXXU1APF2_G935FITV1APE2_ITV
If flashing succeeds, and you still have the same problem:
go back with your device where you bought it
You can't solve it yourself, and probably something is wrong/defect with the main-board
When you 1st discovered the continuous reboot:
1. why did you not go to the store where you bought your phone?
2. why trying to flash "other firmware" on your phone instead of your "original firmware"?
What's your original CSC? Flash your phone with your original phone's CSC and bring your phone back for repair and/or replacement!

Oh dear ! Thats not a good sign.your motherboard is acting crazy.try flash twrp again in odin and try to flash rom without wipe cache or dalvik cache (just wipe system) and flash rom.
If same error ( invalid argument) shows again then in twrp advance wipe there is repair tab at bottom in twrp try to repair cache partition and try again.
Hi there, I have been using S7 Edge SM-G935F happily and a couple of days back installed the BlackDiamond NFE and was not able to connect to the cellular network or make any calls or use mobile data
Again I tried the OneUI and Pixel Experience and all seem to end up with the same problem.
Inserted the SIM into another mobile and there is no problem with the network or the SIM.
Please help me fix the problem, tell me what do I need to flash/install/update.
I guess you need to reflash the stock rom with Odin.
Thanks for the reply @ariondoneda I will flash the stock rom and will let you know how it went. Cheers
Thanks for the reply @ariondoneda I will flash the stock rom and will let you know how it went. Cheers
So, after downloading various firmware from SamMobile and all versions of Odin, I was able to flash the latest BTU firmware and with Odin v3.14.
The problem is still persistent, the same Three SIM when inserted into another mobile and in the same location gives a signal strength of -63db which is very strong.
But, when inserted back into the freshly flashed S7 Edge hardly gets any signal -113db, which is very weak
I ran out of options and looking forward for some help in getting back those signal bars back in my mobile.
Hoping someone in here knows how to solve this weird issue
Just came across such issue with another guy yesterday.. your efs got corrupted/damaged. You have to fix it either using hardware box (a local repairer shop can do)
Or
Try following this thread to word.. should give you signals back (tested by me) ..
https://forum.xda-developers.com/s7-edge/how-to/fix-imei-downgrading-g935f-fd-t3947911
Note : flashing firmwares again after fixing by above method would negate the fix. Above fix needs to be done after every firmware flash to get signals..
Thanks, @shan22 for pointing me in the direction of a possible solution link
I followed the guide word to word and got a success message from the box and it did reboot like mentioned in the 13th point of the guide
The final result is a no change and still, the same signal strength which is very weak of -113db and most of the times it is emergency calls only

Did you flashed csc or home_csc?
Try flashing dbt firmware (with the same bootloader number as your current firmware and using CSC file (NOT Home_CSC) and then doing a format data in recovery)
Then reflash btu firmware (with CSC file, NOT Home CSC) and do a format. Then retry the fix I mentioned in previous post to word..
Also tell me whats your current bootloader number.. if its less then 7 we can try fixing it via combination rom..

A) Always a CSC and not HOME_CSC.

A) Installing the firmware as I write this.
Then reflash btu firmware (with CSC file, NOT Home CSC) and do a format. Then retry the fix I mentioned in previous post to word..
A) Will do and update you

Hi @shan22, thanks for all your replies and time to help me out. Here is what happened. I flashed the DBT firmware which was a success and after the flashing, it started into its default recovery where it said "No command" with a dead droid symbol and died and went into the loop I forcefully started the phone into download mode, installed the TWRP, restarted into TWRP, formatted the data and started the phone into download mode, flashed the BTU firmware which also succeded and went into the same loop of "No Command". This happened a couple of times and none of the DBT or BTU firmware did actually start the system. I had no choice and finally had to install the "PixelExperience_Plus_hero2lte" custom ROM zip from TWRP which worked previously and is working now. All of this effort and it's still down to the same problem, no signal at any time
Sadly, the bootloader version is 8
Yeah version 8 .. no dice. Weird, does your phone gives any error when it gives dead android ?
Looks like you get a dm-verity error upon flashing stock firmware..
Trying flashing no verity zips in twrp after flashing stock rom..
So, your efs is indeed corrupted.
Retry all the procedure..
>flash dbt in odin using csc (not home csc)
>flash twrp in odin and boot into twrp directly without booting into phone
>flash no verity zip, then flash latest magisk zip in twp
>boot into phone
>go in download mode again and flash btu in odin using csc (not home_csc)
>flash twrp in odin and boot into twrp directly without booting phone
>flash no verity and magisk in twrp
>boot into phone and see signals..
If no signals, then from this point refer to my above posts where i gave a link of box like software to fix signals. Follow that thread to word and you should get better signals.
That's the thread : https://forum.xda-developers.com/s7-edge/how-to/fix-imei-downgrading-g935f-fd-t3947911

A bit of progress now. As soon as I flash, I need to disconnect the cable from the phone to boot into anything and I am carefully using the auto-reboot option in Odin.
I flashed DBT using CSC, the flashed TWRP and went into it without booting, flashed no verity, then Magisk and boot into the phone. (No errors this time)
Went into download now, flashed BTU, then TWRP and went into it directly without booting. Here when I try to flash the no-verity or the Magisk, I am seeing the error "Failed to mount /data (Invalid Argument)" followed by "Unable to mount storage" error.
Same with Magisk and if I try to wipe the Dalvik Cache or Cache.
The phone is now stuck at the flashing Samsung logo when I start it normally.

Oof lol
You need to format data under wipe options and type yes after booting first time into twrp and then flash no verity zip and then magisk ..
This is a standard root procedure for root on android oreo, I hoped you would know that ..
Do this and re-follow all the steps I mentioned above ..
And please read forums thoroughly before messing with your phones.

Hi @shan22, did the steps you mentioned and passed the /data unable to mount error, followed the instructions of installing the DBT first and then BTU, somehow got the signal but, not strong as the other mobile on the same network shows. I am now doing the steps you provided the link to and will update you. Thanks again for all your help, much appreciated. :good:

You won't get fully normal signals but will get atleast better or almost good signals. Since your factory efs is corrupted, it can only be restored via efs backup and combination rom with matching binary version. Since you don't have efs backup and latest combination roms aren't available, so there isn't a permanent solution for this.

Agreed @shan22 did go through the whole process and there is no betterment in the signal, it's just the same but a bit better than the earlier. I guess I need to look for a combination rom with the same binary:crying:

Sad to hear that, that's why I don't use fully ported/custom roms because they always have a tendency to f*** up your efs, specially if you mess with wrong options or don't know what you're doing.
Even with an efs backup(from when your phone was working correctly), you still need combination rom
And not even paid websites have version 7 and 8 binary combination roms .. the only thing I came across on a lesser known website was that name of version 7 combination rom was : G935FXXU7ATB1 . Maybe it will be of some help to anyone here
