Rooting/Rom Unsuccessful (Bootloop solved SM-G925F) - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hi. I have spent the past 10 hours trying to root my phone and install an XtraLite type of ROM because I am so sick of have 75% of my RAM used up when I haven't even started using the phone. I softbricked my phone, and after hours of trying to solve every minor issue that came up I finally found a solution and managed to flash a stock ROM. I have a lot of questions that I would love to get answers to because I am a little bit confused right now.
My history.
Bootloader
I spent so much time googling this and I decided to trust one site that said, if you can't find the "OEM Unlocked" option in "Developer Options" then your bootloader is probably already unlocked. This was the closest I got to an answer, along with many people with SM-G925F saying the root was successful for them without doing something to their bootloader. Can someone please clarify what I need to do with the bootloader with my EU SM-G925F?
Flashmode/Download Mode
Prior to this I spent very long trying the "adb-windows reboot bootloader/flashboot-windows oem unlock" without any results. However I somehow came to the conclusion that "Download" mode for my Samsung was no different. Any clarification on this subject please?
Rooting
The first rooting guide I trusted was the CF-Auto-Root page. This is where the bootloader question was raised but as I came to the conclusion that the bootloader already was unlocked, I decided to give it a shot. I downloaded SM-G925F file, added it to AP on Odin, and flashed my phone. Now my phone was locked in a bootloop. According to CF-Root page "A modified recovery and cache partition will be flashed, which will install (only) SuperSU, then clean-up the cache partition and re-flash the stock recovery. For the root to work, the device must reboot into recovery. Most devices will do this automatically after flashing these files, but in case that does not happen, please boot into recovery manually.". As you probably guessed, my phone never booted into recovery mode, and I was never able to manually do it either since the phone was in a unstoppable bootloop. Did I do something wrong here or misunderstand anything?
ROM Instructions
My first choice was: http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-3-t3119968
I failed the first step, never even managed to root with CF-Root. And regarding TWRP, I did download the correct version "twrp-3.0.0-0-zerolteeu" I assume. However, many descriptions say my phone needs to be rooted before I can install TWRP so I never tried to install it. Even if, I couldn't find a detailed enough description of how to install TWRP. All it says is "flash it". Problem is, I am not sure if I am supposed to be in "Download mode" and use Odin loading TWRP into "AP" or how does this work?
Never got to the ROM installing, but it would be nice to have something more detailed than "Put it on your phone, install it". Like, do I enter recovery mode and navigate to the rar file and chose to install it? Not sure how this works.
My solution to bootloop
This part took me the longest. For those stuck in a bootloop. Holding DownVolume + Power button for at least 15 sec will simulate disconnection of the battery. This helps you turn you device off. Also, if you nothing happens, make sure you unplug the USB cable as it keeps trying charge and show the status it tries to boot and keeps looping as a result. I could always manage to get into "download mode" through DownVolume + Home Button + Power Button no matter what, and I am grateful for that. I managed to find the exact build I was using on my phone "G925FXXU3COJ1_G925FOJV3COJ1_G925FXXU3COI9_HOME". But everytime I tried to flash, it always failed in the end. I spent hours on google. Someone mentioned something about it failing on a certain point of the writing, involving hidden.img. I googled for info on how to resolve this, and someone suggested to rename hidden.img to hidden.tar but it did not help. I also read some threads regarding using a matching PIT file and there were about 7 different ones to chose from. I tried them all without success. Finally I read something about removing hidden.img from the ROM. I renamed the ROM from .tar.md5 to .tar. Unpacked it, and then repacked it without hidden.img using tar-Tool from these forums. The following flash of the new created tar.md5 (without hidden.img in it) was successful.
Slave for stubborness
Unfortunately since I spent so long getting through this horrible experience, I would feel bad have wasted an entire day just to get a phone that is now reset. I could have done that in 30 seconds. However I am persistent to get this working and I am truly grateful for any help you people can supply my with. I did manage to root and ROM my old S3 but that was a while ago and I only remember a few small things about Odin and so forth. However things seem much more complicated now than before.
Thank you in advance,
Alex

Could I get a bit of help with a relatively lame brick?

Wellp, I tried to install Cyanogenmod and it bricked the crap out of my phone. I followed their guide at http://wiki.cyanogenmod.com/wiki/Samsung_Vibrant:_Full_Update_Guide and got to the "The Samsung Vibrant now has ClockworkMod Recovery installed. Continue to the next section." step and upon my phone's startup (with the added Clockworkmod flash screen) was greeted with nothing but a black screen. All I see is the samsung "S," glowing for ten or so seconds, like the Windows logo, then it goes black. I tried One Click Unbrick (http://forum.xda-developers.com/showthread.php?t=1153310), which restarts my phone, and brings me back to the same screen. Next, I tried doing the three button (sound-up, sound-down, and power) boot into the Android System Recovery program. There, I deleted the cache data, all user data, and attempted to reinstall packages, but I got a "failed to verify whole-file signature" error, as well as a "signature verification failed" error. I also, tried to re-flash via ODIN, but the only way to get it to see the phone is to boot it to the S logo screen (and the darkness beyond). There is the no-man's-land that Odin detects. Unfortunately, Odin gets stuck at the connecting step, and goes no further (unless that takes more than a few minutes). Fun stuff.
I'm sure you get people asking for help all the time, so I am very sorry to be yet another person asking, but this is quite the frustrating brick.
I am able to boot into download mode, as well as the android recovery menu (the aforementioned area with clear cache, user data, etc.) so I have found a bit of solace in those facts.
Thank you so much for your time.

which rom did u come from?
Froyo. I followed the guide to a 't' and got this black screen. I have no idea what I did wrong.
Well, I need to run off to work now, but I'd really appreciate any responses.
It seems like my phone isn't being detected by odin or windows when it is in download mode, though windows does recognize that a Samsung USB device is being connected. This is recognized in the windows tray (under the name "Samsung_Android"), and in Heimdall's Zadig driver tool ("Samsung_Android").
Hmm first tthings first, your reinstall package error seems pretty simple, yu dont have the right update.zip and recovery combination... if u wanna solve that problem, find the recovery 3e to 2e tool (google it) and run it (follow directions).. then you can run reinstall packages (might havr tto do it twice). If that doesnt cut it, find the CWM update.zip and put iit into the root of your internal sd card (the 12gb one), then run reinstall packages again. You may have to reinstall packages more than once.
Your odin problem might be caused by a lack of drivers on your comp... go on the android dev section and look for a thread talking aboout ms64 and 86 drivers samsung something...
If you can get into download mode, you can unbrick your phone so dont panic
Now odin is a very dangerous tool imo so if you really are sorry about askint, do us a favir and read the sticky oon how to odin before you use it so you dont have to come back and ask us about how to Really unbrick your phone
Also, your brick is referred to as a soft brick and the android recovery program is referred to as recovery mode.
And if you really **** up, we now have the unbrickable mod in the vibrant android dev section which will unbrick your phone no matter wat (it takes somr hardware modifying though)
Sent from a cell tower to the XDA server to you.
And if i were you, id redownload the cm7 package again to make sure that it wasnt a bad download and id read some general vibrant info before diving into cm7... if youre running stock recov and have never odined before etc, youre prob not the best candidate for flashing.. just my opinion
Sent from a cell tower to the XDA server to you.
Thank you very much for your reply. I couldn't find a related tool with the Google search string "3e to 2e recovery tool vibrant," but I did find a modified 3e tool at dkszone(*)net/bypass-e-signature-verification-fail-issue-on-samsung-vibrant-android-2.2 . However, this gets stuck at "checking for temporary root."
As for installing drivers, I have installed the Samsung galaxy 64 bit drivers several times now, but I'll give the 32 bit drivers a whirl as well.
I am unable to access the SD card, and don't have a mini SD card reader, so that compounds the problem (damn my lack of cash!).
*Edit* Upon my attempted installation of the 32 bit drivers I get the following (word for word) "Swallowtail has being used. You need to eject device and reboot your computer. Rerun (Japanese or Chinese characters) after reboot your computer." Google returns zero results when I search for this error. I tried rebooting my computer and running it again, but got the same error (even with the phone unplugged from the computer).
*Double Edit* I've been trying to use the AIO Vibrant Toolbox to restore my phone to factory defaults, but I've been having no luck, as it claims my phone is not in USB debugging mode (and obviously I can't change this, as I have no access to the Android OS).
Try this, mate and hopefully you will be up and running soon...

When I run this the program handshakes, downloads the pit file, then restarts and "...Local and device PIT files don't match and repartition wasn't specified!
Ending session...
Rebooting device...
Device not connected.."
It reboots to the black screen of death and stays there. Perhaps I could select "Flash Bootloader," but the warning of possible permanent damage scares me.
According to the thread...
"REPARTITIONING ISSUE WITH HEIMDALL 1.3.0
Heimdall currently has an issue with repartitioning. 99% of the time you will not need to repartition. Failure to follow these directions can possibly lead to bricking:
Do not flash bootloaders if you see this message:
Code:
Local and device PIT files don't match and repartition wasn't specified!
This message means your partition tables do not match the firmware."
So I guess one of the roots of my problem is that my partition tables do not match the firmware. I have no idea what to do about that.
In this case try another computer if you can, install the right drivers and see odin recognizes your phone. I'm sure it will, for some people sometimes it takes fair few tries for no reason.
Another suggestion, take out sim card and external sd while connecting in download mode. Sometimes that helps.

Here is a recent thread where someone had issue with odin connection.
http://forum.xda-developers.com/showthread.php?t=1225197#16797271
Well, I ran Heim one click on another computer and had the same boot-to-blackscreen process happen.
I was, however, successful at getting Odin to recognize the phone with AIO vibrant toolbox. Odin kept getting stuck at "set pit file" though.
Baby steps...
This is so frustrating. I feel like I'm so close.
How do I get the right PIT file on my phone if ODIN is getting stuck at that step?
Now, after installing the drivers provided with Heimdall-one-click's Zadig, ODIN doesn't recognize the phone.
One step forward, two steps back.
*Edit* Nevermind, got ODIN to recognize it again by uninstalling/reinstalling all related drivers.
Then odin to stock with tthe stock jfd files.. follow the manual, report results

Use those files and the procedure for ODIN.
As for what caused your problem. You flashed a clockwork recovery for a different phone, possibly the Vibrant (non-MTD) mode? Usually installing Clockwork on the Vibrant only works from ROM Manager app when its running stock JFD. At least for me anyway. Any other ROM it ****s it somehow and I end up in a situation like yours. Not to worry though. Here's a quick install guide after you ODIN the phone to stock.
Put latest nightly of CM7 on the phone memory (not external microSD)
Install clockwork (Easiest way to do this is put the update.zip file I've attached onto the root of your phone memory, not the external microsd card, then reboot into recovery (hold both volume buttons and turn it on) and select Reinstall packages twice. It will then boot you into Clockwork).
Wipe data and cache in clockwork
Install zip from SD card--> pick the latest CM7 nightly.
DONE.
I'd like to use those files, but every single link is broken...
*Edit* Never mind. Found another source. I'll post upon success/failure.
*Edit again* Actually, it doesn't seem like the new link on mediafire has all the files required by the process (OP: http://forum.xda-developers.com/showthread.php?t=734475), and I can't post in that thread (because I'm a new user).
This is the post that uploaded the files: http://forum.xda-developers.com/showpost.php?p=17512889&postcount=615
So I haven't changed a damn thing yet, and all that happens when I try to put the phone in download mode is | Phone----Warning (!) Sign----Computer | screen comes up.
Even when I only plug it into a power outlet...
Flashing the IPhone was easier and more stable than this, years ago. I honestly expected better from Google.
*Edit*
OH MY GOD. Odin is going somewhere! Go, AIO Vibrant Toolbox, Go!
*Edit again*
And it stopped at about 90% with "<ID:0/003> dbdata.rfs
<ID:0/003>

Well, I tried again and everything finished uploading, and got the green "pass!" for the first time in Odin.
Now my poor little 959v is stuck in a booting loop. The Samsung Vibrant screen comes up, disappears, comes up again, disappears, ad infinitum.

959v is the not the vibrant, tis the galaxy s4g, if you odined vibrant files on your 4g then that's why you are in a bootloop
Dear god do I feel stupid. I googled it a while ago just to be sure, and it seemed to say that the V stood for "Vibrant." I guess that would be why I've been having this sneaking suspicion...
Well it's good news for you, mate. Head over to galaxy s 4g
forums and hopefully you will be able to get your phone back.

[Q] odin failed, flash recovery.bin cwm

i was trying to root a phone for someone and after odin completed it said it had failed.
the phone is a telus samsung t959d running froyo.
I followed the instructions from (I would post the url for the link but i am not allowed to.)cyanogenmod's wiki, after it failed I rebooted the phone and it got stuck on the screen in the attached pic. I have tried to boot back into download mode to no avail. From the screen it's stuck on I cannot get any tool to register the device as being present, adb, heimdall, zdiag, etc... I even tried fastboot out of desperation.Before I used odin I tried to get the phone to boot into the bootloader but it only ever went to either recovery or a normal boot and I tried every button press combo I could think of and found and nada.
Even running adb reboot bootloader just made the device boot normally. I think that if I could get it to boot to fastboot usb i could then try fastboot. I am new to rooting devices and have successfully rooted my HTC EVO3D and got s-off and simlock removed for any carrier. So I do know how to follow instructions properly, why flashing the recovery.bin failed I don't know and every fix I seem to find says BOOT TO DOWNLOAD MODE. if I could do that I wouldn't be having this problem lol. Anyway can someone please help me figure this out. Thanks. ANd if you need any further info please let me know. I don't want to have to give my friend my phone due to a software issue.
And YES I did pick PDA not anything else.

I kept reading other threads and sadly I din't pully the battery first before disconnecting the usb and repartition may have been checked as I see that it does the as default for my version. Also i turned off ODIN as I was hoping a reboot of my computer might help. I will keep trying to find an answer till someone gets back to me. this post may not even show up if I can't do a second post if no one has replied first.
Everyone was a nub at one time wasn't it FUN hahahahahaha sob cry

I tried a jig and that didn't work. There must be some way of getting the device to give up on completing a task i no longer can give it due to ODIN being shut off.
Why is it that the "how to root/unlocks" never have the "if x fails then do these steps etc..." Had the how to had "pull the battery before disconnecting USB and don't reset or shut off ODIN" I wouldn't be in this mess. I realize that it's user beware but a few important steps like that in case of a fail would go a long way to you guys not shaking your heads. Instead of "silly nub hahahahahaha". No offence but I get that a lot and try to remember that when I teach someone how to use a computer. I am new at phones not at everything.
Further Developments Please can someone help?
I was giving someone a new memory card and they had a Samsung SGH-I896 it has an EB575152VA battery and the one I have the T959D has an EB575152VU battery. I exchanged my battery for hers by accident somehow and when I plugged my phone in it didn't go to the phone triangle computer logo screen it booted to recovery and said it couldn't charge the battery and kept rebooting to recovery. I got my battery back and it booted back to the phone triangle computer logo again. Grrrr....
The other thing I saw while the recovery screen was an error message that said
Code:
E:/data/fota not accessible
(may not be 100% accurate I don't have the battery to check right now but can get it again if need be) anyway I now see that there may be some light at the end of the tunnel. i have the correct stock firmware for the device I tried flashing it while in recovery but the phone kept rebooting before anything got done. My question is how can I get the dang phone to stop asking for Odin and go to recovery so I can flash stock firmware and ROM back to it? As I cannot as far as I know give it what it wants because I reset Odin and nothing seems to see that the phone is connected to the computer. I am going to try the other battery on a full charge to see what that does.
I am new at all this and want to get it fixed. I cannot afford to send it off to a service center and besides that I want to do it myself as I want to become a developer and droid technician. I would gladly donate to anyone but am still trying to get Google to accept my pay-as-you-go credit card and I don't have PayPal either. Which is really frustrating when it comes to giving back. I posted a Q&A on how to without PayPal or CC but as of the last time I checked no one has gotten back to me about it.
The CyanogenMod guide is flat out WRONG. I've tried to change it, but anything I do is reverted in an instant. I also tried to use it to install the ROM only, ended up bricking my phone and it took me hours to unbrick. That's how I became acquainted with XDA.
So, to get this straight:
1. you're using the stock USB cable
2. you remove the battery
3. you hold volume down
4. you plug in the usb cable
5. after a few seconds, you release volume down
6. the screen does not display a yellow triangle with an android

That is correct. If you think that my idea below is a bad one or if I downloaded the wrong firmware package please let me know and /or you have a fix that will work? ty
I have though come up with an idea that may work. I am going to charge the "wrong" battery in erm the right phone lol and then use it to trick the device into booting into recovery instead of the cellphone triangle computer (CTC, for want of a better acronym) The I896 battery ends in a V not an ? (sorry can't rem don't have it on me) from the I896 model I think it is, plugging it into USB with the power off sends it to recovery with the "battery cannot be charged " message instead of the CTC screen.
I tried it but the charge in the battery was too low and rebooted. I am hoping that with a full charge (as long as I don't power on the phone first as this will make it go to CTC logo again.
I am hoping that I can install the update.zip that I made by first unzipping the T959UVJFD_firmware.tar I downloaded then unpacked and then repacked into an update.zip as I don't think that it will read the package as a tar file and if it's not called update.zip The recovery is still stock. If I get the phone working I am not going to try unlocking and rooting it again. I will just post two separate adverts one as a carrier locked device and the other one (higher of course to cover buying the unlock from Telus) as carrier unlocked and then I will buy the unlock code if the blah blah you get the drift. sorry for rambling on.
oh and I can't rem if I said this or not, In recovery it "E:/data/fota not accessible" I don't know what that means yet I have been busy with other things and haven't looked it up yet.
Since you can get into at least some version of recovery, your bootloader is intact and you should be able to unbrick it. You ought to be able to get into download mode using a download jig. You can get one on ebay for a few bucks or you can make one yourself. There's a guide floating around here somewhere that lets you make one from a microusb cable.

[Q] ill pay money for help. brick

LG C800
Device will not enter fastboot.
Can't get into recovery mode.
Each time it boots it hard resets. There is an unofficial CWM Recovery Rom on this forum from chui101 which is for this exact phone, but I have as of yet not had any luck in getting the phone to take it.
So far i've tried Flash_image recovery.img (renamed chui's CWM recovery file to recovery.img)
Doesn't seem to matter what I do the phone starts(LG on screen), resets (the LG goes away for a sec then comes back), does a hard reset (a white box with an arrow pointing out of it an to a little android), again resets the phone one last time for a "normal" boot.
I've tried a few different things to try and flash anything overtop of the stock recovery but nothing works. It seems like very early in the bootstrap is a command to do a hard reset and anything that gets put in AFTER that command is ignored. (And the phone hard resets and anything else it was supposed to do is gone.)
Device is rooted with SuperSU.
Phone is fully functional except that it hard resets every boot, and if its plugged in when off it doesn't go to a charging screen, it starts the phone 100% up.
Adb devices CAN see the phone.
I CAN get into Download (sometimes called Emergency) mode.
"reboot recovery" doesn't do anything but reboot the phone as described above.
I can't afford a new phone guys, so I'm over a barrel at this point.
i'll pay whoever provides meaningful help in getting this thing fixed.
You should start fresh. So, flash the stock rom FTF of your phone, then the phone should boot up normally. Then you could either root it and install a CUSTOM recovery, or flash a pre-rooted custom kernel that already contains a recovery. From there, just flash the custom rom you want
Just press thanks if I helped, no need for money
stock rom FTF?
From the factory?
I'd love to do that. But am bewildered as to how when every guide I've found says use fastboot -- which doesn't work on my device. And every guide without fastboot thus far has not worked. I've been reading 10 hrs a day for the last 3 days looking for a solution to this.
If there was a way to completely wipe the entire phone and then install stock rom I'd be glad to do it.... I have found no such guide... only those to replace recovery. (not a 100% clearing as if it came right off the line with no software yet installed)
Additional information:
mv /system/recovery-from-boot.p /system/recovery-from-boot.p-bak
Spits out a "No such file or directory" error
I don't know about you, but for Xperia Devices there is a PC software called Flashtool to flash stock roms and custom kernels and stuff from the PC. There should also be a software like that for your device. You just download the stock FTF for your phone (just type in google "download stock FTF for LG C800") and flash it in Flashmode that should be working
One more thing, this issue is not called bricked
press thanks if i helped
There is an LG tool but it says current software is up to date.
Other option is run recovery, which just reboots the phone as is.
No, this software I am talking about is not made by LG or Sony in my case. It should be a general tool for all LG devices. it should root, flash, install busybox, etc......

ok, a couple cyanogen dev's have both told me i'm screwed. Imma try for the rest of today and then just never turn it off again.
ok, paying lg to fix it... anybody guess what that will cost?
Try flashing CyanogenMod on your phone as no stock firmware is avaiable currently for your phone cyanogenmod shall fix the problem and you should boot normally (first flash CWM)

Flashing cyanogenmod (requires usb debugging on)
First to put the cyanogenmod rom in the sdcard use adb push - http://forum.xda-developers.com/showthread.php?t=1667929

hi techmasta,
I'd love to flash cyanogenmod, but the phone never enters fastboot to flash anything. The first link you posted says to use fastboot. I can't do that. The phone doesn't goto fastboot, it runs its recovery first.
EDIT: if there is a way to force it while the phone is in download mode that could probably work.
secondly, I've spend more than 40 hours on this issue, mostly reading forums but still a great deal on google.
I'm pretty unhappy with google as neither of those droidnoob forums ever come up. And believe me, there isn't much out there referring to the lg c800 so they should have!

[Q] Samsung S4 I9502 root / flash failed - NEED HELP

Hey Guys,
I tried to root my Samsung S4 GT-I9502 (OS Android 4.3), for that I found this website:
http://marrkdaviid.com/2013/08/fix-caller-id-install-google-play-on-the-galaxy-s4-i9502/
But it failed (more information below) and I had the following error message and no wifi.
I am able to put the device into download mode, though I keep getting this error message when I try flashing the device in Odin.
(here someone with a similar problem: http://androidforums.com/international-galaxy-s4-all-things-root/768632-sos-cannot-open-gt-i9502-after-failed-boot.html)
"Complete(Write) operation failed."
When attempting to flash the device, it quickly goes through boot.img, recovery.img and system.img (when it should take longer for each step, and you should see the little green progress bar move), before failing. Does this mean that Odin is having issues writing to the device?
I live in China and I just bought the phone, I needed 5 days to download the necessary files, because most download pages are blocked in China. So I am loosing my last nerve right now.
I am pretty confident that I have the correct Samsung drivers installed. I don’t have Samsung Kies installed. I have even tried using a different computer (Laptops), and two different ROMs.
I have tried flashing the below ROMs:
I9502ZNUCMG2_I9502CHUCMG2_I9502ZNUCMG2_HOME.tar.md5
I9502ZNUEMK3_I9502CHUEMK3_I9502ZNUEMK3_SVA.tar.md5
Someone with a the same problem tried the 'Firmware upgrade and initialization' option in Samsung Kies, but it didn’t work, so I didn’t try. (Here the link: http://forum.xda-developers.com/showthread.php?t=2382979)
Instead I tried a recovery. I used Odin 3.07 and the following file:
i9502-cwm-recovery.tar.md5
I got my phone back to work for a while, I reset the phone, just in case. But know I can’t switch the Wifi on and the phone wants to Reboot.
So I allowed the phone to Reboot, I clicked on “reboot system now” and then on “Yes – (I forgot what was written behind the Yes, but I didn’t just click on the normal Yes, I clicked on the Yes - …)
The problem here: The Phone changed to a China Unicom Screen and stayed like that. After 5 h I took the battery out, but I couldn’t restart the phone.
So I did an cwm recovery and know I am afraid to reboot. The Wifi is not working and I can’t find any information about how to fix it.
So please help me. Do I reboot? Can I already install SVA ROM, although I couldn’t flash the Stock Firmware? Do I send the phone back and give up?
Please let me know if you need any other information to be able to help me.
PS: This is the first time that I flash a smart phone. And although I already spent several days now, searching the internet for how-to-dos, tips & tricks, guidelines, Q&As and god knows what, I still do not fully understand what exactly I am doing here. Hence, I would be very happy to receive somewhat easy understandable answers.
Thank you so much for your help!

What worked for me to fix: The frp lock Soft-brick (using Samsung Smart Switch)

This will save you 8-12 hours of your time if you are lucky. This means that it also includes the meaningful links of 8-12 hours of searching. Sentences in italic are important. 1 link is for the Odin official website, the rest are re-links back into XDA.
The device in question is a SM-925T Tmobile S6 Edge.
The problem was this. I rooted my phone and messed around with Greenify and the Play store. To prepare for rooting, I allowed unknown downloads, unlocked the bootloader, and turned my security lock off (I had set it to a finger print lock). After I was done rooting, I immediately locked the bootloader again(<--A mistake that caused my bootloop/ soft-brick). After I was finished messing with the above apps (Greenify, etc), I wanted my phone to restart. So I held the Power button and selected restart, while I was on the lock screen (may not be important). I noticed that it took a long time to restart, and upon closer examination, I noticed another error under the "kernel is not seandroid enforcing" (which appears to be natural for rooted phones). The error was "Custom Binary blocked by FRP Lock". It was a new error. I investigated this new problem using the internet , and this dude was panicking like hell, but he didn't appear to fix his problem. He did hint that returning to the bootloader to its locked state was a mistake. Looked a bit more and this guy pointed to another thread, which introduced me to flashing and more importantly his fix, which was to flash the stock 5.1.1 image through odin. He used this link, which contains all the stock firmware for the majority of the new Samsung S6 and S6 edge versions. To make a long story short, most of these fixes involved flashing your firmware to the stock version. So I went to the Odin Website, and downloaded every version, as a couple threads have said that different versions worked for them. Here is a thread with everything you need for Odin. Now, after sorting through and finding micro USB cables that are detectable by Odin, an important step because Odin might develop a pattern of detecting then failing to detect your device through that cable, and testing all the usb 2.0 ports, I was ready, and had Odin with my stock firmware. Odin kept saying "NAND Write", then in the next line "FAIL". This was annoying as Odin wouldn't detect my device again unless I unplugged it, restarted it to download mode, then restarted Odin before plugging it back in. I got confused and found links for somehow fixing the .tar files, stock roms, .pit files (DO NOT MESS AROUND WITHOUT KNOWING WHAT THOSE THINGS DO), and other threads/websites that say to boot into recovery mode , factory reset, then wipe your cache. I could only do that once. After me messing around with all of the above file variants and supposed fixes to help with my issue, I couldn't boot into recovery mode, it got stuck on the "Samsung Galaxy S6 Edge" logo. It did not fix the NAND write failing. There however, are a lot of websites allowing you to download stock software for your phones, and I don't think I can link them as it might break a rule. Surprisingly, some have claimed that using a stock file for another device worked to fix their problem. This thread, which convinced me to use Smart Switch when it failed for everyone else, was very useful, although I recommend downloading Smart Switch from the official website of Samsung. None of the Odin flashing had worked so far, including the Roms and .pit files so I tried Smart Switch. I opened it, and upon selecting the "more" tab on the upper right corner, a bunch of tabs drop down. One should be "Emergency Software recovery and initialization". I had to find my S / N (Serial) number, and I was very confused on how to obtain that number as I was locked out. But to obtain it, do the same process to boot into download (hold volume down, home key, and power key), but stay on the prompt and don't go to the screen that has the word download in the middle. Don't do anything other then reaching the prompt confirming if you want to install a custom ROM. Then, press the home key and it should show your S / N number along with your IMEI number. Once I imputed the code I saw on my phone into Smart Switch, it told me to connect the device. Now, by this time, I realized that Odin only detects my device if it is actually in the download screen. Why shouldn't my computer? I booted into Download on my phone and followed the steps on my computer, making sure that the computer can recognize my phone while it is using a valid USB port and Cable. And after some waiting, for me, my problem was fixed and I could use my phone again, it reverted to it's out-of-box state. I hope this drawn out but very specific explanation helps you guys. It's my first post And also, this thread confirms that you can use a USB hub for flashing(at least for ROMS), Smart Switch, and for rooting.​
Thank you for this detailed account, however nothing of the above has worked for me. Odin won't flash the firmware of 5.0.2 (and I tried 5.1.1) and Smart switch does not recognize the device to do anything. BTW phone has been rooted for months and last night decided to turn on its FRP lock randomly and now I'm stuck. Any help would be greatly appreciated.
Explain throughly what you have tried. Especially different ports, cables, and computers. Did you have the right device drivers? Did you do anything else?
I followed your footsteps and and the step where it has to show me the S/No and IMEI, it only shows IMEI number. I am unable to find the S/NO any suggestions?

press vol down home keys and power key once you get to the first blue screen release vol and power keep holdind home but I already tried smart swich didn't help
5.1.1 has FRP lock auto turned on whenever you have a google account on the device... This is probably going to cause a lot of problems with all newer devices that get rooted. I even tried removing all google accounts, flashed recovery and flashed boot img back to stock after rooting and still FRP was bricking the device. I got supersu onto the device, all working fine for a 3rd time, as soon as I added a google account onto my device and restarted, it was FRP lock blocked and soft bricked again.... I used kies to restore to factory again, re-rooted it for the 4th time when I finally discovered an option in developer options called OEM unlock, Turning OEM unlock on turns off the FRP lock security feature.
My conclusion, If your going to root 5.1.1 make sure you remove all accounts from the device first, do not change google passwords for 72 hours prior to rooting, once rooted, YOU MUST TURN OEM Unlock ON in settings>developer options before adding any google accounts to the device.
Hi everyone!
I also got a Samsung S6 Edge + from a friend with custom binary blocked by FRP. I don't know what he was planning to do but I guess it was rooting.
He said he want me to backup any files before I try anything. Don't know how to proceed. But as suggestion, I want to ask if using "fastboot oem unlock" command would fix that.

I'm pretty sure fastboot isn't for Samsung devices. Hard to back up any files u less you can get into TWRP or the phone. If you flash stock firmware is highly likely the files will be wiped

There is no TWRP recovery on the phone. Yeah you're right about backing up files. I don't even know how to proceed and I can tell you I have huge experience on that stuff, rooting flashing custom recoveries and roms, etc... but in this case, I can't say if files can be backed up.

The only way is to 're flash the exact same firmware he is currently using now using the 5 files firmware package. But yo ensure csc_home is used so the data will not be wiped.

Thank you for you reply.
Please can you tell me where I can find such software or how to do it clearly! I know how to use Odin but I don't know how to exclude user_data to be wiped. Thank you

Thank you thank you thank you!!! This is exactly what I was looking for I had just rooted my note 4 running 6.0.1 and had no idea what the oem option was as no rooting method talked about it at all so naturally as soon as i added my Google account phone restarted and locked up.
Kies was the answer I needed as frp lock was active in download mode and my factory reset in recovery failed everytime but running Kies firmware upgrade and entering my model and serial number it installed perfectly in download mode with frp lock still active saved me alot of hassle ?
