4th day on bootloop. Use 2 min and help me!

So it's my 4th day on bootloop and i still can't figure out how to turn my phone on again.
I know how to push files to TWRP. I have Odin ready. I have 2-3 different stock ROM available.
Flashing stock rom doesn't help - even if i put Nand erase all.
Kies or Smart Switch doesn't help me neither.
Tell me what to do - please.
Bootloader, modem, rom, kernel, put files to TWRP or?
Just 2 minute of your time would be greatly appreciated. Please!

Boot into TWRP and go to Wipe, then Advanced Wipe. Check off data, cache, and internal storage, then swipe to do the wipe. Once complete, power off the phone.
Next, boot into Download Mode and flash your latest local stock firmware via Odin. Once the flash is complete, the phone will restart on its own.
The above steps put you at a clean slate. If it's still bootlooping at this point, it's most likely a hardware issue and the phone will need to be replaced.

i bought it brand new in a sealed box off kijiji. i have the box but i dont know where the guy bought it from. i need the reciept to replace it. other than that, i can use warranty to get the phone repaired. i already sent it in and they changed teh battery but that didnt work. is there any way i can find out where the person bought the phone? the person is not replying to my text or calls

So Samsung sent it back to you and it was still bootlooping when you got it back? That's bizarre. I'd send it in again and attach a note.

It's not that easy to replace the phone when i have tripped my knox which means my warranty is off. That is the problem.

I know, but there isn't anything else that can be done.
It sucks, but it happens. I've had phones die and I had no choice but to go out and buy a new one. It's the risk we take when tripping Knox.

Why don't you provide us with more details...:/ For example which model phone you have (920F/I/T/V/A/etc.) Bootloop means you soft bricked it afaik.
In this case use ODIN 3.10.7 and take a look here http://forum.xda-developers.com/galaxy-s6/general/project-zero-pac-firmware-pit-file-t3181133
1. Put phone in download mode + open odin ( = the phone is detected aye?)
2. Extract the FAC firmware you downloaded (if i am right it's 1 .tar file and if there are multiple you put modem in CP, bootloader in BL and phone in AP)
3. in AP put the right FAC firmware from the thread mentioned above, if its just 1 .tar file (use G920FXXU2BOG8_G920FOXX2BOG9_XEO_PAC.zip if you have the 920F)
4. In the tab "pit" select the pit file you downloaded for your device; e.g. 920F = G920F_EUR_OPEN_HIDDEN150M.pit
5. Start odin and let it succesfully finish
6. let phone reboot.. it will be on the samsung logo for maybe 10 min?

This is the message i get from Smart Switch when trying to flash stock android from the program.

Urgent help needed odin fail

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?
Sent from my SM-G920F using Tapatalk

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.

You can't use any of the CF auto-root files if you're bootloader is locked. If you are using the US model S7, you can't unlock the bootloader. You'll have to flash back to stock firmware. Download mode = Volume down + home + power. Hold all three down, in that order, until you see the 'custom OS screen' then press volume up. Even if you brick using CF root files, download mode should still work. I have a G930U I tried to flash with CF (a few times before I figured out the bootloader was locked) and I have been able to get to download mode no matter what I flashed, so far.

Hi,
I have a S7 930U that had FRP, I used combination firmware to enable developers mode on, then flashed with several firmware that I found online for 930U, but the phone will boot fully, then reboot within 20 seconds. the vicious boot cycle continues no matter what firmware I put in. I'm thinking I still haven't found the correct firmware for my phone, which is causing the boot loop? Please advise what I should do.
I'm trying to flash again with combination firmware so I can collect all the CSC and related details so I can search for the correct firmware in SamFirm. Please advise.
Thanks.

If you can enable debugging and PC recognizes it, plug it in to PC > go to my computer > right click your phone > properties. That should tell you enough.

I thought I found the right firmware with the region code XAA and phone model SM-G930U using SamFirm. Flashed it, booted and it seemed like it was working, but the cycle started again!!! I don't understand why the phone would just reboot when it's being setup. shows setting up android, this may take 3 or 4 minutes, then just shuts off and powers back up.
on the back of the phone, it has this G930UZKAX. Is the region code embedded in that string? if it is, I can't figure out what region code this phone is! Can someone please help me obtain the PDA, CSC and region for this damn phone? I'm about to smash it on the wall.

S8+ Stuck on boot loop

I can’t seem to fix my s8+ when I try to Flash anything in Odin I keep getting complete (write) failed. When flashing stock firmware I keep getting (...) Fused 2 > Binary 1
Or it will fail to erase
I cannot boot into recovery at all - freezes/won’t even boot there
Normal boot or safe boot doesn’t matter either sends me to the blue screen where it loops either Erase or apply update and then about 5-10 lines of code then reboots.
BTW it’s the SM-G955U1 model unlocked
If someone would link me to the latest firmware that may help. If the latest Oreo beta just to get out of this mess that would also be appreciated too.
Also when I open up smart switch it says the device is incompatible with it.
I will edit with video of the issue
Edit:
well i got it up and running, i guess it came down to the BL being Ver2 and because of that it would prevent me from installing anything that ran on V1/rev1.

well now a new issue has popped up... No service.... Prob because its using 955u firmware and im not using the main verizon carrier -- im using flash wireless...
my phone and pc recognize my phone as a 955u device .
is there any way for me to go back to 955u1 firmware? Please help.
will i be able to switch when samsund decides to release the oreo for the 955u1?
Thanks

Fixed finally
For all of you out there who happened to get stuck on 955u firmware containing bootloader 2 installed on the 955u1, there is hope!
I have successfully gotten back to 955u1 firmware and running OREO.
You will need (I will give Links to files in a post to follow) (Carrier in BL says XAA):
USB 2.0 PORT
PRINCECOMSEY ODIN 3.12... link
regular ODIN 3.13.1 (what i used) link
G955U1UES2AQL1_G955U1OYM2AQL1 Firmware (link in post to follow)
G955U1UEU2CRB9_G955U1OYM2CRB9 Firmware (link in post to follow)
Official Samsung Cable that came with phone (preferably)
Windows OS
A Galaxy S8+ 955u1 Phone (only tried with this)
Instructions:
1. Extract both firmware files/zips (Put in 2 seperate folders so no mixups)
2. Reboot your phone to download mode (Power off then -- Power + Bixby + Volume Down at same time)
3. Open up princecomsey ODIN and then connect your phone to USB 2.0 Port
4. Add in the AQL1 Files - (BL, AP, CP, CSC) -- (I personally first did the AP, CP, and CSC then had it reboot then i restarted and flashed the BL by itself then rebooted) and press start. (I unchecked everything but reboot and f.reset time)
5. Unplug and Wait for it to turn on to the setup screen, then finish the setup. If you open up settings it will be all jumbled up and weird, but dont worry. If you dont have service yet - dont worry.
6. Now after the phone is all setup (or if you decided to skip), unplug and power off the phone then boot into download mode again.
7. Now open up Regular odin and reconnect the phone
8. Now put in the CRB9 files (BL, AP, CP, CSC) (I put all in this time and i used the Home_CSC this time but you can use csc normal but no guarantee that would work with getting service again as i didnt try it) and press start and wait til it finishes and reboots
9. ENJOY!!!
I will make a new forum for this tutorial soon

SOLVED: N986B/DS KSA and Odin is failing to flash. Would greatly appreciate assistance. Thanks!

Condensed for brevity:
Unlocked bootloader and Debug USB enabled. Went to flash an AP and it failed. Tried to use Frija to get the most recent update, found N986BXXS3EULH REV01, tried to flash the AP/BL/CP/CSC to refresh the phone and it's failing.
Everything matches my phone when I typed *#1234# (EULB/EULH) except the download has REV01 added to the end.
Phone is stuck in download mode no matter how I reboot it. Phone isn't bricked but won't do anything else.
Edit: Updated to using Odin 3.14.4 instead of 3.13.1
Edit 2: Figured out the phone is freezing after any fail (brightness doesn't change with volume keys). I get the failed PIT as well as "Can't open specified file (Line:2006)"
Edit 3: Re-opened Frija and it gave me an entirely different FW this time that superseded what I had on the phone originally and the DL'd file (*3EULH became *3EVA9).
Tried to use new CSC and it keeps failing at prism.img. It's progress but not really at the same time.
Edit 4: It lets me install the BL and CP for either/or EULH or EVA9 but neither CSC or AP work ever. I'm thinking I just have a bad firmware or something.
Final update for the night: The files are good. Compared hashes across multiple downloads. Phone isn't seen in Samsung Smart Switch and there doesn't seem to be a recovery menu. TWRP or otherwise.
If anyone has any ideas please let me know. I'm pulling my hair out because it's brand new. All I did was try to start by updating the stock firmware with Odin (after bootloader unlocking and USB debug enabling) and this happened.
-------------------------------------------------------------------------------------
Day 2: Moved back to Odin 13.1 and extracted PIT from EULH CSC, installed it, then did the BL/CP, installed fine. Still froze with CSC/AP. Then attempted to try it all at once. PIT, CP, BL, CSC, and AP. It actually starts installing now. But it specifically always freezes at the super.img portion. So while I'm unsure what's going on now since I'm still trying to install the correct official ROM, I'm starting to think the ROM is somehow incompatible with my phone.

HERE'S THE ANSWER! Many thanks to those who attempting to help. We were doing and advising everything correctly.
The problem is the PC itself. Which was why the issues seemed so varied. I attempted every USB in my computer, none would flash (they drop out randomly with my phone), and the first sign I didn't realize was a sign was the phone wouldn't work on my USB-C ports, only 3.0/3.1.
I run a Threadripper 3960x on an Aorus TRX40board. I had to go to a 2015 touchscreen laptop to do this. If you're having issues then literally try a new PC if possible. If you see that it isn't connecting to Odin on USB-C, then you may well have the same issues I was having.
Note: this may be a driver issue, as I used every one of my 20-ish ports and they all still failed, as well as about 5 different cable options to go between USB/USB to C and USB-C to USB-C.
