[Q] Last resort before i have to replace :/

Yesterday i decided to test few roms out so i backed up my current and flashed.
had no problems until i flashed cognition 2.3b2 , after i had i felt i didn't like it and went to restore my backup. Instead however i received errors in the recovery and it seemed to restore way too quickly still with errors. As of that point my phone will not boot my screen seems to glow after hitting the power button but nothing ever comes up its completley black , i can however get into download mode and i have tried numerous times to restore with odin , instead of restoring to stock though it gets stuck on odin at :
Code:
<ID:0/004> File analysis..
<ID:0/004> Set PIT file..
<ID:0/004> DO NOT TURN OFF TARGET!!
<ID:0/004> Get PIT for mapping..
<ID:0/004> Firmware update start..
<ID:0/004> Sbl.bin
and occasionally at :

<ID:0/004> boot.bin
<ID:0/004> cache.rfs
<ID:0/004> dbdata.rfs
<ID:0/004> factoryfs.rfs
the only thing i can think of that could have caused this is possibly voodoo being enabled when i tried to restore. If this is the case , is there any way to fix it , assuming people have done this before.
If all else fails i will just get the phone replaced, not an issue of money however there is a lot on my internal that i would like to keep , would there be any way to get it off the internal without having to start the phone , maybe through download mode ?
In advance, thank you

Man, that sucks. Have you tried one of the one-click odins? I think there's a one-click that can take you back to stock JF6, and I know there's a leaked 2.2 one-click floating around. Maybe you will have better luck with those, since they're all-in-one packages?

thanks for the input, The problems im having are with the stock jf6 one click odin.
Should have been more specific ,
This 2.2 one click seems promising though, im willing to try anything at this point!

Here's what I would do:
0. Download ODIN3. http://forum.xda-developers.com/showthread.php?t=731989
1. Pull the battery, sim card, and external SD card.
2. Start ODIN3.
3. Insert your battery, then press and hold the volume buttons.
4. Connect the phone to your PC.
5. Click start.
Once the new ROM is installed, boot the phone and enable USB debugging. Start ODIN3, connect the phone, then click master clear.

This is what ive been trying to do,

Reflash At&T Froyo

I did something stupid. Upgraded to At&T froyo and then used Titanium backup to uninstall the AT&T bloatware. However my phone started acting funny. So i put my phone on download mode and started ODIN. However the ODIN is struct at

Edit:
I pulled the battery out. They try to get back in to download mode. It works. But still ODIN is stuck at

Please help . thanks a lot...

I followed this http://forum.xda-developers.com/showthread.php?t=775911 thread to go to download mode. Finally ODIN flashed 2.1 back..
However, i wonder why it didn't work the first time when i went to download mode...
Thanks a lot

Typically this happens when you didn't follow the strict order of operations using ODIN. You must start ODIN first without the phone connected. Then put phone in download mode and connect to the USB cable.
Also, you may need to use different PIT files and select re-partition when switch between 2.2 ROMs and 2.1 ROMs. If you use OneClick ODIN, it already put PIT files in for you IIRC

Blaze Hard Bricked

Long Story Short:
I think I hard bricked my blaze
LONG STORY:
1. I tried flashing CWM into rooted konane's kernal (Stock ROM)
failed numerous times , accidently left "Re-partition on" ; but still the phone booted fine
every thing was working ;
2. Went into CWM ; made a nandroid backup
3. installed Dknight rom
4. Flashed Dknight (Wipe cache ; davlik cache wipe; then flashed)
5. phone never booted beyond the RED ORBS
6. I realized Now Im soft bricked
7. went into odin tried the soft brick method ; failed all the way
8. "Firmware upgrade encountered" error message ; phone is not recognized by windows neither kies nor ODIN
Conclusion:
I think I hard bricked
I NEED HELP !!!!!!!!!!

Not hard bricked that's soft bricked luckily for you and that's just another form of download mode
Take out battery and dc from USB cable now with Odin open and USB cable connected to PC only. Then put battery back in and hold the two volume buttons and plug the USB cable into phone then you will again see ur screen but Odin should recognize iit now ans well flash the tar
Just fyi if your phone turns on to any screen it isn't hard bricked
Now if it doesn't turn on at all then it might be hard bricked

If helped don't be afraid to hit the thanks button it doesn't bite lol

I did that same crap when i first rooted this phone i didnt realize repartition rechecks it self that little silly [email protected] progam made me think i destroyed my phone but...eventually found a guide on google but what erik said will fix your issue, just to verify.

are you getting the same screen as atifahmed33? with the "Firmware upgrade encountered an error"? if so, do what erikmm said:
disconnect usb
pull battery
open odin application
put battery back in
plug in usb cables
push and hold BOTH volume up and volume down
press and hold power until the download mode warning screen pops up
release all buttons held
press volume up once
voila! you're in download mode
Odin should now recognize your device. if it doesn't, verify your computer recognizes your device (in windows, go to computer management->device manager, cant remember in linux, who cares in OSX, its an inferior OS)
I must have soft bricked my phone about 10 times over the weekend forgetting that stupid little check

I cant remember if you need the drivers too...

Check and see if that fixes. Also are you getting into download mode?

I ran into a similar problem yesterday while trying to Odin back to stock. Couldn't figure out what going on after 2 or 3 unsuccessful attempts. I redownload the tar file several times, and decided something else had to be the culprit. And VOILA, it was my usb cable. It wasn't connected good, I think my port is a little loose. So before I clicked "start" in ODIN, I held the phone in my hand and made sure the usb had a good firm connection with the other and it worked. It may work for you as well.

[Q] can't get into download mode

So I was trying to root my phone. Kinda went through a quick crash course of it with Odin. For some reason it kept hanging up at boot.img but that's a different story. Long story short, after numerous tries, I forgot to unclick repartition. Why it clicks itself when you load up the PIT is beyond me. Personally, I think the developer got a kick out of people bricking their phones that way. **** him/her. Anyway, I can't get into download mode anymore, even with a JIG. Anybody got any ideas before I send it for JTAG?

Please everyone refrain from posting the rule about searching and reading as this should resolve itself (should the OP actually search and read).

I've searched through enough threads as it is with a combination of different keywords and all I've found is a bunch of people explaining how to get into download mode or others saying so and so can be fixed as long as you can get into download mode. With the latter, if you can't get into download mode, then what?

Just for the record, I've already tried reflashing it to stock with a .tar file. That failed miserably.

Kind of an improvement as before it would just hang at boot.img but now at least I can get a confirmation of whether it works or not. Currently the phone is still showing the "Firmware upgrade encountered blah blah" crap. But I tried it anyway as I read that it's supposedly a front.
Can't get into stock recovery either. Top left corner says Odin mode. Odd as the JIG puts it into Factory mode. I've uninstalled/installed the Samsung drivers several times. I've changed the USB cable to a Samsung one that I got like a month ago. I have Kies installed. Can't connect the phone to it either. I've tried flashing with Kies not installed and with it installed and shut down/not shut down. Don't think I missed anything else but if I did I'll add it.

I believe that has been discussed also. Pull the battery, re-enter download mode and flash again. When it doesn't complete properly it won't let you Odin again until the battery is pulled.
Just curious but are you on ICS 4.0.4? If so the Odin root is exclusive to gingerbread... Odin cwm and a flash a rom or just Odin back to stock. Root through ICS is obtained by flashing supersu zip through cwm when on ICS.
I realize you are frustrated, but the devs here are awesome and deserve respect, especially since they just brought 4.3 to us.

Got it figured out. I was surfing the other subforums and landed on the thread talking about Odin 3.07 and I figured why the hell not. The flash to stock was a success. Then I did the root and CWM Recovery. All is well. 3.07 is much better than 1.85. For the record, I am on GB. Thanks for the help. I apologize for earlier as it was indeed frustrating.

Problem with flashing, stuck in bootloop, can't turn off phone

So basically I have a FRP locked S7 running nougat (not anymore ). I tried various guides to bypass FRP lock, but none worked. Stumbled upon this guide, and got Custom Binary Blocked by FRP Lock. Searched some more, found out I should downgrade to marshmallow (apparently) to make it work. Started up Odin, and I only loaded only the AP, found a video of a guy doing it and working, but in retrospect I think I should have loaded the bootloader, etc.
Long story short, after I rebooted the phone after flashing, it got stuck at Galaxy S7 logo, and I couldn't turn the phone off for the life of me (held power button for like 10 minutes). Simulated battery pull command just restarted the phone, still stuck. I let the battery drain, thought I could charge the phone while off for a bit, put it back into download mode, and try to reflash back to 7.0 or something. Same story.
Any advice or ideas would be greatly appreciated.

On your second Odin flash attempt did you include all 4 firmware files (CP, CSC, BL, AP)? If not, do it again using all of those, and don't use HOME_CSC

I only flashed once, just with AP ticked. That's when I got stuck in bootloop. Now I can't get the phone into download mode. It's fully discharged now, and if i plug in the charging cable it just starts on S7 logo and freezes again.

Give it some charge, then try get into download mode with USB disconnected. Even when on the Samsung logo, the download mode combo is meant to interrupt and reboot no matter what the phone is doing, but when USB is connected it goes into the charging state.

Charged it for a bit, removed cable, stuck on S7 Logo. Proceeded to apply home + vol down + power, phone restarted, back at S7 logo still stuck.
LE: Kept holding download mode combo, managed to get it working. Will update soon

Are you releasing hole + vol down + power when it restarts or holding it the whole time? You should be holding it until you get to the download mode screen.

Phone says SW REV. CHECK FAIL. DEVICEL: 2, BINARY: 1

What version did you start on, Nougat? And you're trying to go back to Marshmallow?
It could be that the last bootloader version that came with Nougat prevents downgrades, but if you flash to Oreo first including the newest bootloader, you should then be able to downgrade from Oreo to Marshmallow.

Yes, it was on Nougat. Will try to flash Oreo. I`m guessing there's no way to bypass FRP on Oreo tho ? Also thanks for all your help so far ! :good:

Yea Oreo is as secure if not more secure than Nougat, the only FRP bypass methods I'm aware of only work on Marshmallow.

You can use Odin to repartition when there's boot issues, but it's risky and I'm not personally familiar with the correct way to do it.

Pretty sure yeah. Phone is from the UK. In download mode it says SM-G930F, and when I could get into recovery up top it said G930FXXsomething something
LE: Trying to flash nougat back, see if I can at least get it back working the way it was.
LE2: Same SW REV CHECK FAIL with nougat as well :|
LE3: Managed to flash nougat back just by writing the AP, phone now started normally. That just leaves the problem with the FRP lock, so I`m back to square one )

Why does Samsung disallow downgrading? Why can't we just tick a box that says "I understand that the security will be downgraded too" so their butts are covered and we can have what we want? What a dumb move on their parts... Obviously not gonna blame Samsung if someone got my info because I choose to downgrade...
Btw been trying to do the same. I rooted first and made a backup before messing with things. Only tried the 2 things, got in a boot loop but was able to reflash twrp, then booted into twrp by pressing the download buttons combo, but switching to recovery combo as soon as the screen went black. That worked. For now restored my backup.
But I'm determined to figure this out one way or another. SO many people want to downgrade, so why isn't Samsung listening? "Everyone hates nougat, but hey let's make Oreo exactly the same..."
Ugh sorry just frustrated right along with you!

You cant downgrade U2 to U1, efuses prevent this! Try to FRP unlock your phone though G930FXXU2DRAG firmware of UAE, its the only one that worked with z3x and octoplus boxes for me.
