Hello. Unfortunately i bricked my phone. Here is the story.
I root the phone with cf auto root. Install recovery, but i forget to make EFS backup. Then install Bootloader and Modem PF1 for G925F - TWRP from carhd thread and then the rom itself. After that i lose mobile network. I can't use my sim card, no IMEI, baseband unknown. Since i don't have EFS backup i tried to flash every stock firmware that i can and nothing fixed the efs. Everytime when i flash stock firmware and reboot the device after flash, the phone boot in stock recovery and it says: "dm-verity verification failed...need to check drk first . The only way to boot the phone is to install twrp and install no-verity-opt-encrypt-2.1 but still no sim detection and no IMEI.. Smart Switch is not working for my phone. How can i fix it?
Lately I've seen so many bricked s6 due to not backing up efs. The most important thing is always make backup.
I had the same error and problems as you and all i did was flash stock to fix it. Try to flash a stock with a newer bl and modem. If stock doesn't fix it im not sure of another way

This guy had exactly the same as you and flashing stock fixed it. Read the posts and flash the fw and pit from there.

Yesterday I was trying some new roms and maybe I screwed something. I did try a 4.1 official samsung rom downgrading from 4.3. I had the IMEI problem but I fixed it flashing a stock rom from my carrier through Odin.
I even have an EFS backup folder in my extSD.
I've tried to flash again CM11 but it fails. All other custom roms fails too. It read "Fail" in TWRP.
What should I do?
I tried restoring the EFS folder with the backup too, or maybe I did it wrong... Don't know.

i tryed to install the ROM again but it didnt helped...
i can get to the recovery and download mode, but my phone still stuck on the stuped logo...
what to do?
sry if i have spelling mistakes...
You have corrupted one or more partitions, try a factory reset after flashing your custom rom again.
If that doesn't work then use Odin to flash a stock firmware, then factory reset.

Means you screwed the efs partition when flashing an incompatible modem with your efs version.
If you flashed a 4.1.2 firmware and got that error, try and flash a mg4 or above modem to see if it gets solved. Or flash a 4.3 firmware altogether.
Read rootSU post on efs, it's a must.
Of you ever backed up your efs or used twrp recovery to make a nandroid backup (which also backs up efs) you might get it back by restoring it.
Otherwise, a patched kernel, modem or ariza patch would be the last available choice before sending to repair.

I mean, go to the stickies in the general section and read. They're there for a reason, including steps before rooting, flashing, information on the efs partition, and pretty much everything else you could have done to avoid the situation you're facing right now.
Hi
I reccently bought i9300 ( hongkong ) and it came with 4.3, i tried rooting it with CF-Root, The process itself completes with no problem but when i open SuperSu, It asks to update binaries but when i do it fails.
All of the fellow xda helpers have suggested to install CWM and than flash Update SuperSU ***.zip from chainfire, I did that as well ( i flashed the latest zip) But the problem is there.
Can anybody help me with that?
The CF-ROOT and flashable supersu i have flashed are:
UPDATE-SuperSU-v1.91
UPDATE-SuperSU-v1.86
UPDATE-SuperSU-v1.10
CF-Auto-Root-m0-m0xx-gti9300
CF-Root-SGS3-v6.4
Now as i am not rooted so i can't backup the EFS (i don't want to take the risk of loosing my IMEI) and flash stock 4.1.2.
-----------------------------
Here are the details of my phone:
Model no: i9300
Android version: 4.3
Baseband: I9300XXUGNA8
Kernel: 3.0.31-i902166 [email protected]#1
Build no: JSS15J.I9300ZSUBNB1
------------------------------
Thanks
Backup your data.Try to use factoy rom (XXUGMJ9) for odin with pit and repartition.. Flash philz touch recovery and flash lastest update-supersu-v2.01 and should work without error.

i already did a backup through cwm, Is it good enough ? as i have read in the forum that if you dont have efs backup and you flash stock through odin, you may end up with lost imei; That's the boat i don't wana be on ... so i await your response on that.
Also can you guide me or give me a link to PIT and Repartition stuff, as i am new to samsung, i moved from htc.
After flashing stock, philz, do i need to flash cf-root through odin or update-supersu will do the rooting trick?
Thanks for your response

You should only use pit files as a last resort! Use only if your phone is not booting or major problems like that and definitely not because you can't root!
If you flash latest PhilZ there is a option in the settings to fix supersu try that way first or try a different version of su from playstore.

using odin i have installed latest PhilZ recovery, although the superSu is having the similar problem but i was able to find " backup efs" underr custom backup, i think internally my phone is already rooted, as custom recovery went on smooth. Will that efs recovery be enough to bring my phone IMEI back? Can you suggest what else should i backup ?

If done properly then yes also I would also suggest making another backup with PhilZ recovery there is a option in settings to do that ( you can never have too many backups) also if you want you can do a full nandroid backup which will restore your phone to how it was before you flashed anything.(but remember nandroid won't backup efs you have to do that separately)
For any fellow xdaz who are seeking help in the same case as mine, Let me update on what i did and what went wrong (although i am still not upto the rooting part)
so as i was on 4.3 ( I9300XXUGNA8)- The rom won't let me root, whatever i did, and i am talking about clearing cache, dalvik, cf-root, superSU update, clearing all superSU app and reinstalling via market and odin.
Than i thought i would ditch the rom and maybe downgrade ( for me that was the wrong idea )
along the way ( as suggested by " tallman43 " i did install PHILZ and did custom backup of efs and i made around 4-5 backups, Big thanks for the awesome suggestion ....i suggest you do the same, as trust me i later found out that 1-2 backups have corrupted files ( i don't know why).
i also downloaded neat rom and in that Aroma installer (rom installer) there was an option for efs backup as well, so i did that and installed that rom. Rom installed without any problem, root was also working fine, i personally love the rom but i have to give my phone to someone and i was hoping for total stock whereas in neat rom there are tags here and there, i would love to have em but as i said earlier...
i downloaded Stock 4.1.2 (I9300OZSEMK2) -- flashed it, flashed went fine but now i got 0000 as my imei, i tried restoring through philz but nothing happened
i restored previously made backup of my old 4.3 but now the imei was displaying " NULL "
finally i stopped there and searched the forums and read through many similar problems, i downloaded 4.3 (I9300XXUGNA8) from sam mobile , flashed it and voila the imei and network is back.
I am not sure what fixed the imei and why was it giving problems on 4.1.2 but i am happy with the results.
I will update for the rooting part and that would be my next step.

I came across this thread as I am facing the same problem with rooting.
I was on a rooted i9300 and did an upgrade to 4.3 via Kies.
Now when I run through the rooting process using CF method, Odin posted success.
I see inside the console (while flashing cf auto root) that SU binaries are being installed and all. But once the phone reboots, root checker reports phone is not rooted.
I tried a couple of other ways and the closest I got was to see TWRP recovery console once, but once the phone reboots, and I try to go back into recovery - it is still Samsung's recovery console.
Actually all I want is to flash a custom ROM because the phone has been running ridiculously slow. Can I flash it through Odin (under AP) or I have to use a custom recovery like clockwork or TWRP.

If you want only to flash a custom rom then you do not need to root custom roms come already rooted (alot of people make this mistake )..Just flash a custom recovery with Odin then follow the procedure in the stickies to flash a custom rom.
I started the night by downloading a rooted kernel for the phone and installed that using ODIN. All good.
Next I installed a TWRP recovery image using the flashify application from the app store. That works and were still good.
Then I had to flash a "modem" and "bootloader" for marshmallow (note I do not really understand what these were for, i was trying to follow a guide).
This is where it went screwy, after flashing these 2 files for my specific device through ODIN, it would not boot.
Im not sure but likely to make things worse, I attempted flashing a new TWRP recovery version because i belived it would work with the modem and bootloader.
Ive now tried flashing the stock firmware using ODIN but i get a FAIL message. Please please help, i only just got the phone and i feel hopeless.

use samsung smart switch to restore ur device to factory settings
it will fix ur phone back to normal
If smart switch doesnt work download your stock firmware from sammobile (make sure its the correct variant. Also were your updating from 5.0 to 6.0?
Phone: [Samsung i9300 international ]
Hello XDA. I was trying to restore the EFS in this phone with the GalaxySim unlock App right after flashing the Slimkat ROM which gave me a no signal problem. The IMEI appeared as unknown and baseband too so i proceded to trying to restore the EFS backup i had in my pc.
I followed the procedure by doing tap in restore EFS in the app , chose the EFS folder option and then restarted. After that I can only see the Samsung logo and doesn't boot. Since the beginning i got this used phone I could never load the custom recovery (TWRP) from the button combo, it always went straight to Odin telling me to press vol up to go to download mode.
The only way around to get to TWRP was by using Goomanager and using the reboot to recovery mode option. That's how i managed to install the Slimkat ROM. After that I always get the red exclamation sign while booting but still everything was fine except for the phone signal not working at all.
What can i do now by using only download mode? What are my alternatives?
I hope you can help me.
Thank you.
EDIT 1:
I managed to boot to TWRP with adb shell by "adb reboot recovery"
and when i try to flash a custom ROM or the backup before the Slimkat it shows this error:
"E: failed to mount /efs ".
EDIT 2:
So now that it's a EFS failed to mount case , i'm following this:
http://forum.xda-developers.com/showpost.php?p=37533150&postcount=12
but i dont know what version of busybox to download. Which binary should i get?
I recommend that you stop flashing anything else on the phone until you confirm that the model # is gt-i9300 in download mode.
After confirming the model #, download the latest stock ROM from sammobile.com and flash it in Odin. Boot the stock ROM and see if the imei is properly displayed.

This is on the back under the battery:
Model: GT-I9300
FCC ID: A3LGTI9300A
SSN: I9300GSMH
Also when I try to charge the phone by the wall socket the battery animation seems to be just frozen. Which stock ROM should I download? Does it matter the country? I don't know from which country might be this phone.
Have you had the from new or did you get it used?
If you got it used, I wouldn't trust the label. You should confirm the model number in download mode.

It's correct the model, it's a used phone and:
Custom binary download: yes (11 counts)
Current binary: custom
System status: custom
Flash the latest stock ROM from sammobile.com with Odin. This will remove root and don't forget to perform a factory reset before booting the stock ROM for the first time.

I have never found the country to make difference so pick a country closer to you with the language you need.

Thank you for your help. It worked and now its running a stock firmware but I cant get wifi working on it, it keeps saying connecting-saved-secured and reconnects. The phone signal its fine and can make calls without problem but now i flashed TWRP and It doesn't let me get into it nor with the button combo or the Goomanager. I want to backup this EFS asap and try another custom ROM.
You can't get into recovery mode at all?

I can at the moment, it was just USB debugging that was off. Again i used the adb command to reboot into recovery. Now , what TWRP version should i get to backup the EFS in .bin or any other format that i can flash with Odin. Can you recommend me a ROM that doesn't mess with the EFS?
I haven't had an s3 for over 2 years but I recommend flashing the latest tar version TWRP in Odin.
Alright, I did a backup of the EFS in .img and a modem backup in .bin with this:
http://forum.xda-developers.com/galaxy-s3/general/tool-backup-restore-efs-imei-sgsiii-t1901098
then i proceeded to flash a custom ROM and wifi works but now the phone signal goes intermmitent, the icon with the bars goes full and empty constantly, it identifies my provider tho. Airplane mode triggers on/off automatically. Should I restore the EFS from stock ?
Edit: flashed the modem.bin from stock. Airplane mode still intermmitent.
Don't touch the EFS if the phone is showing the correct imei. You flashed the latest stock ROM? Does this signal problem happen on stock too?

In stock there was no problem at all with the signal. The wifi thing was my router actually, some authentication problem related with the use of the password.
Edit: flashed another modem that was tested by other user with the same ROM and phone went completely unstable and couldn't identify the network. Went back to my back up of modem, still airplane mode goes on/off.
I suggest flashing the latest stock ROM and then test. I only used stock modems and bootloaders on all of my Samsung phones.
If the phone doesn't work properly on stock, custom ROMs may exacerbate the problem.
After a long day of testing, only the latest stock ROM works properly while every other custom ROM has the same problem with the phone signal, CM11, slimkat... What's happening?
Edit: flashed CM13.. still the same.
Sounds like you are limited to stock or stock-based custom ROMs.
