Hi all I will keep it brief.
I have tried to flash with Odin 3.10.6, 3.10.7, 3.09, 3.10 root, twrp, stock firmware G920F but everything fails at "Nand Write Start" its driving me crazy. I've tried different versions of Odin, Twrp, and even Smart switch multiple times but nothing will write to the phone. ODIN ALWAYS FAILS AT NAND WRITE START.
My phone will only boot into download and NOTHING else not even recovery.
Any help welcome......
Try different firmware revisions. You flashing stock? What was the last fw successfully flashed?

It is Stock G920F (united kingdom EE (EVR).
My problem is No matter what version of Odin or what I try to flash Odin always fails after Nand Write Start. It's not just the stock firmware, it's anything I try to flash in download mode.
Im actually in the same boat just now. ODIN wont flash the EVR Firmware (previously it did, mine fails on the cm.bin). I have tried different ODIN versions and also different laptops. Also the Smart Switch / Kies3 recovery procedure didnt work for me either. I was able to flash TWRP via down and get into recovery, but it see a lot of unable to mounts when trying to flash custom ROM and fails to do so. I think that i might have stupidly wiped via recovery something i should not have as i did noticed before all this i lost me IMEI (unknown).
I always assumed that if you can get into download you would always be ok but this is the first time for me that im having big issues.
I really hope someone can help out other wise i have a really expensive paperweight.

Try to flash latest fw. Probably you've upgraded the bootloader to which cannot be downgraded.

What i've noticed with the S6 (and S7 i presume) is because you can't shut the phone down completely when your stuck on the download screen it never fully resets itself for another attempt at flashing by Odin. If your hold Power+Volume down to shut it off, the screen just goes black briefly then it comes back onto that error message about connecting it to Smart Switch for emergency recovery.
Smart Switch is a waste of time, it will download all the software for your device , say it's going to install then you get an error message telling you to use recovery code which of course it does not give you! So basically you just go round and round in circles with Odin and Smart Switch, i'm convinced it's not being able to shut the phone down completely that causing the problem of failed attempts.
Anyway something you might try that allowed me to flash G920F United Kingdom EE (EVR) PDP in the end. >>>
The phone battery eventually died, i waited for 10 minutes before charging it up to around 15% again, then i put it into Download mode, made sure my windows 10 laptop had "debugging" enabled at start up (i think this is why Nand Write Start is failing).
I loaded up ODIN 3.10.7 with "Cf auto root", connected my phone then flashed the root file straight away. It worked, so i reset Odin, put phone back in download mode and flashed EVR quickly via odin and it worked.
Over all i thin there's 2 issues here: The phone cannot be completely shut down when it will only boot to download or that smart switch recovery error and Windows 10 keeps turning off "debugging mode" which prevent Nand Write to device. I may be wrong but after hours of attempts with lots of different Odin and Firmware thats what i noticed. There has to be a way of shutting the S6 off completely .
NB: Tried latest BTU firmware, won't flash same problem "Nand Write Fail"
NB; Reactivation lock is OFF

There is no recovery code as far as I remember. As long as you have the sn that should make a go.
And there is no way to shutdown the phone completely. We can force reset but it will only shutdown whem the battery depleted.

Smart Switch is useless! I put in the model SM-G920F then the serial number and SS tells me the correct firmware is (EVR), downloads it, prepares it for installing, starts to install, gets to 1% then says "an error has occurred please use the Emergency code below to recover your phone" BUT there is no code! It says Emergency recovery code: .......nothing.
The main issue i'm experiencing is ODIN will not flash anything of any version, always fails at "Nand Write Start".
I've tried multiple versions of Odin, Stock Firmwares, TWRP, Root. Nothing will flash until the battery is dead, then when i try with a little charge for the first time Odin will usually flash the 1st file i give it (no matter what it is) then thats it, back to failing after "Nand Write Start".
Driving me crazy.
Quick update. I loaded a later FW (Still UK) and it passed in ODIN, so that was better.
But after that it booted into stock recovery, showed unable to mount efs (no sim card in). I then rebooted and its been on a blank screen ( with the blue light flashing) for the last 30mins. No real signs of life.

The stock didn't flash correctly then. After you flash stock with ODIN it should reboot into recovery, should just boot into MM, and go through phone set up.
The problem with flashing different Stock firmware (even if it's same region) it can cause all sorts of issues. There's G920F BTU which is the non branded stock for Galaxy S6 G920F then there's G920F EE (EVR) G920F Vodafone (VOD) etc
You'd think the non branded BTU would be fine on any UK S6 but that's not the case unfortunately.
Use Smart Switch and go through the emergency recovery option, one you put in your model and serial number it actually tells you what stock firmware your phone was shipped with, then you find it and flash it through ODIN.

Already tried that. Flashing the EVR just doesnt work, ODIN Fails every time. Smart Switch says it should be EVR based on S/N but i just cant get it flashed.
Dont know what else to try.
Cheers
You might also try Win7 or earlier, 32-bit, if possible. There are known issues with Win8 and later.

Its WIN7 im using on both the work and personal laptop, neither of which have had any issues in the past.
IF i flash EVR, it fails, i then flash TWRP to reboot into Recovery, but i see there alot of unable to mount / error messages, possibly the partitions are damaged? I dont know.

I tried to use chainroot, and got stuck on the logo screen. normally you'd battery pull, go to recovery and wipe data. but i can't find any way to shut down the phone, before doing power-upVol-home.
And now i've tried to odin a stock recovery to undo chainroot, odin fails. could re-run odin with auto-reboot off, but again, no way to shut off and go to recovery.
at this point i'm stuck with the blue screen asking me to use smart switch on PC to do emergency recovery. but smartswitch says the device is not recognized.
thoughts? thanks!
I was stuck rooting on the boot logo too. Had to use odin 3.10 and did "run as administrator". Also if this helps to reboot the stuck phone press vol down+power together until the screen blanks out. If you need to get into download mode, as soon as the screen blanks out, press and hold the Home button ( Don't let go of the vol down and power though ).
Good grief.... the non-removable battery has made these recovery tricks so difficult
thanks twisted_mind. at this point, i only get the blue screen asking me to do smartswitch recovery, and the one thing i CAN seem to do is volDown-power-home and it easily goes to download mode. i have not been able to get to recovery mode no matter what i do (including volUp-power-home, even before this smartswitch message came up after i tried to odin a stock recovery).
so i can still go to dload mode, and stick in a stock rom. the ones i've tried are from sammobile, and a potential issue is that i don't know the exact one to pick (this phone is a demo here in europe and i didn't note the details under settings when it was working). so the ones i try end in an odin FAIL. again, i've also tried odin unchecking auto-reboot, but then the phone is stuck at the very end of dload ("don't turn off target", etc), and i have no way to battery pull, etc.
Instead of holding power to shut off you have to hold power and vol down

Hello
I'm stucked on the same corner, i used Chainroot with odin 3.10.6 with no luck, just as what
happened with you, my S6 international module stucked on logo screen.
where did you get S6 stock recovery from?
Thanks

I have the turquoise screen that says "an error has occurred... use the emergency recovery function in smart switch...". if i do power + volDown there OR when the phone is stuck in download mode after the odin fail, the phone turns off but then comes right back on with the turquoise error screen. i've tried quickly going to the recovery key combo right when or right after the screen goes dark, but to no avail.
I can easily do power +volDown + home and go to dload mode. i just can't get into recovery mode no matter what i've tried so far.
if i could just find a stock rom that wouldn't fail in odin, or something else to use as AP/PDA in odin, i'd be set i think. wish i knew how to do this. hitting nand erase all in odin doesn't do the trick by the way.

I managed to root my G920F after "odin flashing" the UK version from Sammobile, release date 11-4-2015,
Then i flashed back the CF-Auto-Root.
Know my device is booting fine and rooted

is the version you flashed the same version that you had prior (do the apps look the same, etc)?
so odin passed? (mine FAILs, with 4 different sammobile stock recoveries). I have the S6 Edge, maybe the S6 works fine and I just need the correct S6 Edge firmware.

No its not the same version, mine was G920FZDAXSG and i flashed G920FXXU1AOCV, its a UK version, some Version
store apps was pre installed in the rom nothing more.
Odin passed normally with no issue.
i used two identical Odin v3.10.6 versions the second one i used is the one i flashed the rom and the root with.

umm, hey ammsamm, i went to the link you just mentioned, installed it and GOT SOME NASTY SPAMWARE INSTALLED on my machine from it. I'd normally flag you immediately as a bad user, but your other comments sound legit. do you have anything to say about this?

Actually this is not the link i downloaded the odin from i tried to
Atthach the one i have but faced with the upload limit, even
After ziping and spilting the the odin, upload failed,
So, you better find another odin 3.10.6 a version with all the buttons
are enabled.
As the description, silly me flashed TWRP and in bootloop AQF5 for my G955F, can't enter TWRP or start normally.
Read through a few threads and tried the flash TWRP twice and instantly attempted vol up, Bixby & power button after restarting in from odin mode but it just sits in bootloop, boots into odin fine, tried so many time, with no lucks.
I have a Smartswitch backup but my phone isnt being recognised, so I try the emergency firmware route, the download & initialization gets to 83% and I get an error message, so my back up is useless until I manage to reboot or at least flash a new rom in TWRP (if I can get into it)
Just to I'm stock no root, TWRP flash knocked my Knox to 1 which i'm not bothered anyway
Been trying the past 2 days to download from samfirmware, samsung-firmware.org & updato to which my download gets to 40%, 73% and 80% before it decides to start pending then fail when I retry, been on phone to ISP and no problem on my line so I'm strumped and in need of AQF7 BL and CP please....
good thing I have an S7 as a spare

Thanks pal, I ended up downloading AFQ7 after my ISP called me to say they have identified and fixed a fault on my line, my S8+ is back to normal and I've refused to install to AFQ5 update haha think I'll root it tomorrow seeing as I have a way of bringing myself back to stock now
Much appreciated
Can admin close the thread please, problem solved
Hi guys,
I need help with my G955F. I was on Carotid's ROM and attempted to flash the AQL5 (BTU) firmware downloaded from Samfirm to go back to stock. The flash failed during writing the system.img and now it is stuck on the "Error has occurred while updating the device software" screen.
I can get into Download mode and I can boot into TWRP using ODIN.
Each attempt to flash a firmware in ODIN throws up a "FAIL" during the system.img write portion.
Each attempt to reflash a ROM from my external SD card in TWRP throws up an error while writing to system. /System is unmounted when I start up TWRP and I have to manually mount it each time.
The phone is "not supported" in Samsung Smart Switch.
Anyone have any ideas?
Never mind!
I noticed that whenever I plugged the phone into the PC when the "Error has occurred while updating the device software" screen was on it flashed up as "added" in Odin.
So I tried flashing the stock AQL5 firmware while on this screen and it worked!
I'm just going to leave this here because it's an avenue I never considered and haven't seen online.

Good observations.
You are correct, if the first flash fails, immediately re-enter download mode and flash again.

Yeah, but that's the thing. I wasn't even in Download mode for the successful flash. I was just on the Emergency Recovery screen and when I started the firmware flash, a small progress bar appeared on the screen below the text.

Have not heard of that before - new to me, interesting find.
So the way to replicate is . . .
The way I got there was to have a screwed up install. I tried to flash a stock firmware and it generated a FAIL in Odin during the /system.img write.
The phone then rebooted to a pale green screen with a large triangle and exclamation mark advising me that the phone was in Emergency Recovery Mode and I should restore it by plugging it into a PC with Smart Switch installed.
Interestingly, Smart Switch refused to recognise my phone, saying it was an "unsupported device".
After numerous attempts to flash new firmware through Odin and TWRP (even using the two-step method of getting into Download mode) and using different cables/ports I was planning on getting it professionally repaired until I noticed that when Odin was running and I plugged the phone in, with the emergency screen on, it was "added" as it would be during Download Mode.
I loaded up the AQL5 firmware, and tried to flash. A progress bar appeared under the text on screen and it got about halfway through flashing /system when it failed again, but this time it has progressed much further than any other attempt.
I then reset everything, used an official Samsung cable and a port directly connected to the motherboard on my PC (I had been using a USB extension cable before) and attempted another flash and it worked!
I don't know how you would go about replicating those circumstances without risking your phone but if you find yourself stuck in the same situation, give it a try.
It worked for me.
Thanks, ianrobbie.
Hi,
A few days back I bought an S7 and put a custom rom on it (Havoc-OS) however I wanted to put the stock firmware back on the phone so that I could resell it.
And the problems begin. Odin (3.10.6, 3.10.7, 3.13.1 are the versions I've tried) will not work, the phone either does nothing, Odin stays put at certain stages like "NAND Write" or "SetupConnection", and this morning I made a bit more progress as I've managed to get the phone to TRY to flash but the AP fails, so I've tried flashing the BL and CP, CSC all individually. Right now the phone is stuck on a screen saying...
"An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
The problem in doing that is that the software won't work without a recovery code that I do not have.
The only thing I can think of is to try and put TWRP back on the phone and keep using Havoc-OS since Samsung has apparently made it infuriatingly hard (to me) to put their own software back on their phone.
I also have a Galaxy Note 3 and have had very few issues with it... Odin works fine with it, the only quirks with the phone really are with any custom roms I use on it and not the phone itself.
Hi there,
I am trying to repair a stock S7 (G930F) which freezes after an OTA-update. About a year ago there was a similar problem, which I solved by flashing an older firmware and telling the owner not to do the update again. Now the update was done again and this time Odin does not let me downgrade due to "KERNEL REV. CHECK FAIL".
The freeze appears 10 to 20 seconds after reboot. The phone freezes completely and after 20 seconds it restarts. That's not enough time to complete the initial setup or anything else.
I tried many different stock ROMs, full-wipe by stock-recovery, re-partitioning with Odin, safe mode, all with and without SD-card, SIM-card and cable plugged in.
I can't try custom ROMs or TWRP due to the FRP (force reset protection). To disable this a have to login with the previous Google-account... this is not possible within time before the phone freezes. My last idea would be to search for a method to remove the FRP in the darker pages on the web and then using TWRP and custom ROMs. Or the dangerous NAND-Erase in Odin (I have no EFS-backup)?
Any ideas except buying a new one?
Thanks,
Philipp

Philip, it helps if you let us know what country your in.
Anyway the solution to your problem is pretty straight forward, you just need to flash the latest firmware for your region with Odin. No need to mess about with TWRP at this point.
Official firmware will contain a copy of the stock kernal which will also be installed when you flash with Odin 99% of the time. If for some reason the kernal is not flashed (it happens) and you continue to get the reboot issue then you will need to flash the kernal seperately first with Odin then the firmware afterwards.
The issue with the FRP lock will remain after this but should allow you to unlock with google email and password.
So we're talking, downlaod mode, flash official fimrware and go from there.
Hi cooltt,
thanks for your reply. Unfortunately I already tried many stock ROMs. I am from Germany, so of course DBT first (G930FDBT7ESL9), then VIA (Telefonica) and VD2 (Vodafone) since they had higher build numbers. Desperately I also tried other versions to get it running somehow (for example the Polish G930FPRT7ETA9). The kernel was successfully installed with all ROMs.
I was very confused, that this does not work. In my understanding this can not be explained. After full wipe/repartition and flashing stock it should be as "stock" as it can be (and everyone should have these problems). Either all these ROMs I tried are broken, some hidden things like EFS are heavily broken or there is a hardware issue with this phone which made absolutely no problems with Nougat but now with Oreo.
Bootloops after OTA (which are dirty) are usual, but this is driving me crazy. I can not believe in a hardware issue since a very similar problem appeared one year ago with Oreo and there were never any issues with Nougat. But if it is a software problem, more users should have this...

Hello Philip this might be a long post
What firmware was on the device before the problem started? Was it branded or unbranded?
Are you sure the phone is a genuine G930F or a phone that has been turned into a G930F by flashing that firmware in the past? You can check by looking at what the phone model is at the top left corner of "Download mode"
Where are you getting the other firmwares from?
I've attched Samfirm tool which will get the latest firmware direct from Samsung servers.
1. Unzip file
2. Right click on SamFirm application and run as admin.
3. Check "Auto" & "check crc32" & "decrypt auto"
4. Model is "SM-G930F" type it exactly as shown without quotes
5. Region is "BTU" . Offically UK with all EU language options but also additional files which will fix firmware install problems.
6. Press "check update" then "download". It will decrypt automatically and you will have a zip file with 5 files inside(BL,CSC,AP,CP,CSC_HOME) choose CSC not CSC_Home when placing into Odin. Place all other files in right place.
Odin attached is version 3.13b patched. This version of Odin will ignore lots of miss-match device errors and just install the above BTU firmware.

Hi cooltt and thanks for your help!
Unfortunately the BTU-ROM did not solve the freeze-reboot-problem but led to another: After flashing the phone gets stuck with a blue screen "Erasing". After several hours I force rebooted and now it is showing a similar screen with "Error!" and a percentage which is increasing to a random number from 0% to 12% on each boot. On first boot it shows the boot screen ("Galaxy S7"), then "Installing system update" shortly and then "Erasing". After force-reboot it shows boot screen, "Erasing" then "Installing system update", both for a very short time (sometimes misses "Installing...")
As suggested I used SamFirm to download the newest BTU-ROM (SM-G930F_1_20191218140415_dgobhw6g3v_fac; G930FXXS7ESL5/G930FOXA7ESL5/G930FXXS7ESL5/G930FXXS7ESL5). I just ticked F. Reset Time and Reboot. Re-Partitioning did not change anything. Using Odin v3.13.1 does not make a difference. The other ROMs, like SM-G930F_1_20191226131628_8ds2p6kf0v (G930FXXS7ESL9/G930FDBT7ESL9/G930FXXS7ESLA/G930FXXS7ESL9) which I downloaded with Frija (should do the same: download enc4-files from Samsung and decrypt) make the phone going to the initial setup fine, but with the reboot-problem. Tried also with Odin 3B patched.
At this point I was going to write, that I could not access the recovery mode with the BTU-ROM but just now I started it unintentionally when looking for the sequence of screens showed on boot. So I used my chance, made a full wipe and screenshot. After this the phone booted until the glowing "Samsung"-logo appeared. Then rebooted and went to initial setup (after "Androi"Installing applications") in German. The freeze-reboot-issue appears as with all the other ROMs.
The phone is certainly an original SM-930F as it was bought directly from a big, trustworthy dealer and then just used by my aunt. The only one touching it when problems appeared was me. There is SM-G930F printed on the backside and showed in download mode.

Hi Phill
The only options checked in Odin should be F-Reset and Auto reboot. Don't check any others.
The blue screen erasing and updating is normal after a flash with Odin, the phone will restart a couple of times, just leave it do it's thing for a bout 10 minutes or so. If it's any longer than that as you have mentioned then it's stuck as you've said.
So we're going to start from the begining again but do something slightly different.
1. Place the phone into download mode
2. Run Odin but uncheck "Auto Reboot" so the only option checked is F-Reset Time.
3. Use whatever firmware you want, BTU or DBT the latest version. Make sure files are in the correct boxes.
4. Connect phone and flash with Odin, wait until Odin says "succeed 1" and "dissconnected" . It may even say "pass" in green, not important but "succeed 1" is important.
5. Your phone will show the bar and do not disconnect. So....disconnect from laptop / PC. The screen should remain "do not disconnect".
6. Hold volume down+home+power (in that sequence).
7. As soon as the screen goes black move your finger to volume up, while still holding down home + power. You are trying to get the phone into Recovery mode as you said earlier.
8. The option to choose in the recovery menu is "wipe cache partition" NOT "wipe/factory reset". I can see from your pictures that this option has failed because the FRP lock is still on!!
9. When you've chosen "wipe cache partition" then choose "reboot system now"
The phone should go through it's normal set up routine, erasing, update, installing apps etc, just leave it do this and hopefully the phone will boot then ask for the Google email and password which was used on the phone.
There are very few reasons for the phone to get stuck on boot....
1. Incorrect firmware,
2. Water damage
3. The phone has been Rooted with FRP lock on. It is very rare to be a hardware issue.
You should always turn FRP lock off and enable OEM unlock in settings before flashing to a phone. I know it's a little late for that but something to remember.
To check for water damage.
1. Remove SIM card and holder
2. Shine a light in the hole, you will see a WHITE sticker which turns PINK if water has ever got inside the phone.
Thanks a lot again for your great efforts!
I tried as you wrote but did not manage to start recovery immediately after flashing (tried >10 times). But after some while the BTU-ROM started and now keeps doing so even after new flash without wiping cache afterwards. Wiping data worked for me in past when I sometimes had enough time to enter Wi-Fi-password. It was saved even after reboot and away when I did data wipe in recovery. With the newest ROMs I never got beyond typing Wi-Fi credentials.
I cannot see a water damage. A root was never tried before (and OEM-lock and FRP were always on because stock, which is very bad now ). Would be absolutely no problem if this !#@*#% stock ROMs would work... TWRP installation was directly blocked when I tried my luck as last resort. I did not try other images.
Thanks nevertheless for your time and patience!
