I have testet to repair bootloader with JTAG from this thread:
http://forum.xda-developers.com/showthread.php?t=2265477
but the Bootloader was unchanged!
Please help!

If the Odin flash is succesfull using the one part version, then you need to boot into recovery and select factory reset and/or wipe cache. That should probably fix it.
If not, be more specific. What firmware did you try to flash? Also what device do you have? Do you have the GT-I9505G or the GT-I9505?

Thanks for your Answer!
I tried to flash firmware 9505 German DBT with the last xxxMH5.
My Device is an GT-I9505G.
When i tried to boot in Recovery mode in the left corner is written "Recovery Boot" but then the screen turns black and
the device restart.
Flashing i tried both 4 Part and 1 part -> 4 part fails und 1 part is successfull but there is still the bootloop
Tanks for helping Lennyz!

Why do you flash I9505 roms on a I9505G? I'm don't know much about that device, but I thought the firmware can't be exchanged? Or am I wrong?
Do you have an unlocked bootloader? If so, I would try to flash cwm.
If no one else that has more knowledge about this responds in you thread, my suggestion would be the following.
1. Try this firmware: http://forum.xda-developers.com/showthread.php?t=2342377
if that fails
2. Try this method: http://forum.xda-developers.com/showthread.php?t=2360346
But then again, I don't own the device, so it's on you.

Good to hear you got your phone working again.
Try a factory reset, maybe that will help.

[Q] GS4 - How to return completely stock for warranty exchange

Hi,
I've been do many flash last 24 hours on my Galaxy S4(Model SGH-I337M, Telus). Initialy, i've the factory stock rom, rooted. So, yesterday, i've decided to install Cyanogen mods nightly on my phone. Not the first time i've been used it on my phone. No problem before. So, this night, after a friend show me the release canditate release seem to be more stable, i've been try to put it on my phone. So, accidentaly wipe all the data on my phone. When i'm back home, i've put again the samsung original rom from my operator(4.2.2), found here, on the website, whit odin. All completed succefully, but i've noticed that the wifi won't turn on after the flash, and no sound from the speaker. So, i've put Cyanogen nigthlies again to test if it rom relative, but same issues here, no sound, but the wifi was working. The phone was very instable, so. Then, finaly, put the original rom again, without any rooting. Stuck on samsung logo, that i've finaly got fixed by clear the data and cache. But, no sound, and no wifi. Instable too.
Precision about phone: Unlocked whit the service mode(work), and enabled AWS whit a software and file(tutorial found here)
My question is: Anything else i can do to make my phone work fine again, and does it's possible to make the phone totaly stock? When i boot up, i've noticed that the phone, whit all rom i've try, said on samsung logo: Kernel is not sendroid enfonced, warranty status: kernel, so i can't go to return my phone on warranty whit that. How i can erase that line, and make my phone seem to be no modified?
Just to specify, it's not the first time i flash a phone. Do many flash, whit galaxy s2, s3 and s4, and sure, mine. Got try Cyanogen, stock, know how Odin work and all, try many rom, and before today, never has any problem to do turn back, but now, it's seem to be impossible.
Thank you very much for your help, very appreciated!

I would flash the stock firmware with odin again. After flashing do a factory reset in the stock recovery.

I've just try this. Flash the stock rom whit odin, and factory reset on original recovery after. Same, no wifi, no any sound.
Just see yesterday, when i'm flashing, i'm flashing on the bootloader in odin(whit the tar for the stock rom). Today, correct this by flash on the pda section, still not work. Found here on the forum the stock bootloader, rom, csc, and modem, but when i do this whit odin, odin said fail.
Thank very much, i think my phone is dead, and nothing to do to exchange it on warranty.

I think Kies has an emergency firmware recovery mode.... maybe that'll work.

Just try this. Kies is the worst software i've ever see. The software completely freeze random. When i go to the emergency menu, never, kies recognize my phone here. I've tried to plug my phone, no recognized. Tried without plug it, no recognized. When i plug it, kies said connection in progress, and can stay here 30 min.
I'm a idea of what is my problem. Before do install of cyanogen, i've been applied the samsung official 4.3 update, whit knox. And, according to what i read on many forum, knox is not ereasable, So, it's completely freeze my phone, and nothing to do.
Anyone have the factory telus bootloader and other factory stock items because i want to put it stock.
Thank.

Finally get problems fixed by take the TELUS stock 4.3 ROM and flash it whit Odin. After, can flash cyanogen nightlies again and the phone work well again.
Whit the stock ROM, didn't see any line on the Samsung boot logo that i've rooted. After root this appear again. Knox regardless of ROM installed said 0x1.
If anyone have a fix to put it again 0x0 very appreciated otherwise the phone work fine and thank you very much for your help.

@Spacemonkie4207 never my itune was freeze, and i can do basic operation like transfer music or create playlist without any problem. My kies stay on connection in progress, and turn, turn, turn, but never connect. And when it connect, only one operation, and kies completely freeze, stop responding, need to close it, and open it again. Tried many cable, usb cable, reinstalling software, two other computer, but nothing to do.

I recovered back to stock from custom to 4.3 however if you do so, depending on carrier you could lose root and the ability to install custom recovery.
I would revert back to 4.2.2 (as it's knox free) go to samsungupdates (google it) and pull the 4.2.2 for your region and carrier. flash with odin 3.9
you'll lose root, but you can always perform again as long as not on 4.3 (with 4.3 u can still root if you remove all the knox stuff, u just lose warranty).

[Q] Lost EFS potentially

So after flashing a few things, something went wrong big time. Phone barely makes it to the lock screen and when it does, it says System is not responding and then automatically reboots. In that brief time I see the dreaded no signal icon.
Have tried restoring stock firmware via Odin and it still leads to the same lock screen issue every time (used this very same file to restore to stock before without any issues). To add salt to the wound, my SD card got corrupted (stupid SanDisk I should have learned from past experiences) which is where I kept my EFS backup. This is on a N900W8, with Knox tripped 0x1 so no chance of warranty.
Do I have quite the expensive paperweight on my hands here now? It seems so but hopefully there is a light at the end of the tunnel for me

Out of curiosity, did you have the new bootloader or the old and did you try to dowgrade the firmware?
If you did it might be part of the problem...
Reflash MJ7 in ODIN and that should fix it but you will now have new bootloader that will trip Knox counter when rooted.

No I have not tried downgrading, the Odin firmware I use was always the latest MJ4

Since you've tripped KNOX try this link it'll fix your efs issues.

It does work, bailed me out and many others. You'll have to go with a custom recovery though to be able to use it. Just boot into download, install custom recovery then flash the zip fix and you're sorted.

[Q] recovery & rom problem

Hi!
I have been rooting with CF autoroot and cwm (old version 6.0.4?) and Omega V.19. Been having alot of issues with closed calls and freezing. 3-finger recovery/download mode have not worked either. Have to go by "restart meny"... When apps is looking to yppgrade my cwm it doesn't find any for my model!? And so on!!!
Now I have tried to role back to stock (so I can claim warranty), but no succses!
After many attempts I got TW recovery on it, but can only access using the restart meny. Everytime i start it i get seandroid enforcing, kernel bit somthin something... In download mode I try to flash with odin stock 4.1.2 but get fail all the time. Even though I have not gone past Omega V19 i also have knox void 0x1!???
What to do?
Edit:
Got CWM touch in now but no luck witht the rest. As Odin fails I get "unsupport dev_type" on my phone. But I have chosen the nordic version i9505!?
Edit2:
With the exact same basbandversion xxuame2 it worked! but no it doesn't get passed the "samsung" startscreen;( And without being able to go into download mode via restart meny inside the rom I cant flash it!? I have restarted several times and taken out the battery...
Edit3:
So I have got 4.2.2 now. It's not working good howe ever. No WIFI and no calls. BTW it was a two finger combo (without meny) to get into recovery/download mode. How do I get rid of the text up top to the left on the screen on boot? Doesn't look "stock" to me;(
How do I return it to stock. I have no triangle or counter , just binary custom and the 0x1...

SOLVED;
"Official" 4.4.2 via odin solved all my issues Do I have a knox problem now, I dont know!?

Boot to download mode and check.
Knox Warranty Void is probably triggered. 0x1
Anyway, it does'nt really matter.

Yeah if you tried any root method and/or installed a custom ROM Knox Warranty Void would be triggered and after researching there's no way to fix that. The warranty void doesn't affect the phone's performance at all so really nothing to worry about.

Custom binary blocked by frp lock

need urgent help really.
my phone has been rooted and has twrp installed for months now with no issues, all of a sudden my phone rebooted to the samsung logo screen with the mentioned error message. i have no idea how and why this error has occured but my phone wont boot to system. i really dont want flash stock firmware as i havent backed things up, is there a way to fix this issue with out doing a full wipe?

you might have accidentally disable oem unlock. so phone is bricked , and you need to flash stock firmware with odin , no other choices . and as you know knox counter will stay 0x1 , root or no root, once you break knox its permanent as knox is hardware, once you root it break an electronic fuse so once you flash stock firmware I really suggest you to install custom rom and twrp again as many things will be blocked if you stay on stock firmware as your device will stay marked as " rooted "

Yeah I had to do firmware install in the end. It's just crazy though. I very rarely go into dev options, I had noto kernel installed and everything on stock aqh3, rooted with magisk and everything worked great, so annoying as this happened at 3am and I have slow internet connection and took me 2 hours to download the 3.5gb firmware file. Urgh o was on the verge of installing a custom rom too, ah well good job I had a lot of stuff saved in Samsung cloud.

This stock Samsung Rom worked earlier today so it should be the right Rom for my phone.

I tried to add a snapshot here but couldn't.
Anyone please, I'm helpless..

Your issue is trying to flash older firmware than what is on your phone. You will need to download firmware with bootloader ver. 3 or higher ( bl ver no. is 5th number from right of firmware name )
Flashing twrp failed because of locked bootloader.
