I have a i9505.
My phone is stuck in a boot loop. The phone keeps restarting after the samsung logo for normal startup and for recovery. So recovery is also not working.
However phone is working fine in download mode and stays on for as long as I want. So this means that my power button is not at fault.
I have tried the guide here: http://forum.xda-developers.com/showthread.php?t=2265477 But this has not fixed my problem and phone is still stcuk in boot loop.
Please help.
Thank you

Try to flash the latest MD5.tar from here:https://goo.im/devs/philz_touch/CWM_Advanced_Edition/jflte/
After that your recovery should work fine. Flash it through odin3.09 selecting AP. If it don't work uncheck AutoReboot

He/She says that its stuck in a boot loop for both a normal and recovery boot... I think they should flash the original Samsung S4 firmware, then the custom recovery to be safe.
Grab an original android image from http://www.sammobile.com/firmwares/ (matching your currently installed firmware/country), and flash it with ODIN as AP or PDA (depending on the version of ODIN you have), while the phone is in download mode. You may have to flash it twice in a row (I'm not sure why but it works for me).
Then you can flash a custom recovery and whatever rom you wish.

The recovery is not working either. Its just stuck in a boot loop

Hmm, that is weird...
I believe the only other thing to try is to flash in ODIN the partition layout (.pit) file as you might have corrupted it somehow... but I have never done this, so I can't give you any personal advice.
The .pit file is in that thread you linked, as the "I9505_pit file.zip" attachment. See Note 2 on what to do with it.
... Otherwise it sounds like its defective.
Model: SM-G900P
I've tried every kind of rom flashing here, re-partitioning, recovery images, etc.
I really just want to get to the stock recovery mode with out the auto boot loop.
Please help.
What else do you need to know?
Try flashing TWRP 2.8.7.0 with ODIN, and boot into TWRP recovery
If you can get into TWRP, you have a very powerful recovery with a lot more options than stock, to try and get things working again before going back to 100% stock - if that's what you're aiming for

The flash seem to work via ODIN. See image below.
But it is still stuck in a boot loop for normal booting or for recovery mode.
Am I using Odin incorrectly??

A lot of newer S5s do the same thing (Except they usually boot back into stock recovery, but as yours isn't working, same thing)
Follow this guide (Using the correct version TWRP for your model S5)
http://forum.xda-developers.com/showpost.php?p=64961009&postcount=2
You can ignore steps that are not relevant to flashing TWRP, or follow them all for a rooted phone (Apart from reactivation lock as you can't boot yet)

I followed these steps:
"3) boot into download mode.
4) Odin flash TWRP 2.8.7.0 (specifically this version).
5) DO NOT allow phone to boot, (uncheck auto reboot in odin and if necessary remove the battery as soon as the TWRP flash has completed) then.....
6) boot directly into recovery. (Vol +, Power & Home button combination)"
Although, they were not very specific....
To flash with odin, I used the AP button and did not let it auto reboot. Removed battery immediately. tried to reboot in recovery and saw the same issue.
I think I need all files.
BL
AP
CP
CSC
and possibly to re-partition with a PIT file
You say in the first post you have already repartitioned?
PIT file is for repartitioning
http://forum.xda-developers.com/attachment.php?attachmentid=2799613&d=1402839135
Extract to .pit, add to PIT section in ODIN, add ROM to AP section, flash both together
You can try older versions of ODIN for TWRP to, some people have success with version starting 3.07 > 3.10.7
I was able to do the PIT and the TWRP at the same time.
Although, my phone said "SECURE CHECK FAIL : pit" on the screen, it seemed to do everything.
But upon reboot to try to get to Recovery (power, home, Vol+), it no longer waits and reboots/recycles. It fails with a message that says "Could not do normal boot." and send me to Download mode.....
If I try to boot normally, I still get the boot loop....
I just used the PIT file I used last time and it's back to where I was when I started this post.
Endless reboot cycle...
Maybe the bootloader needs to be flashed?
Ok. My issue with the failing pit (and any other failures from Odin) was a combination of using a bad version of Odin or a bad version of the tar or pit files.
I am able to flash the latest stock rom g900p OK4 just fine.
I can flash twrp just fine as well.
But the boot loop cycle still remains.
I believe I know exactly what I need here and it's the stock OK4 boot loader.
Here's an Odin flashable OK4 bootloader for the G900P. https://mega.nz/#!9ItUDZ7C

Bootloader file was exactly what I was asking for. Thanks.
However, it did not solve the problem.
Boot loop cycle going on still after stock BL, Ap, PIT all flashed....
Any other suggestions ???? Please. From anyone?
I'm sorry to write in this old topic, but I want to know if you solved your problem, as I'm having the same trouble. Everytime I turn on the phone it stucks on bootloop, and after 5 to 10 cycles it starts. When trying to enter to Recovery it stucks on bootloop and never enters. I've tried with TWRP or Philz CWM but it just doesn't enter to recovery :'(
Hi there,
I'm experiencing a weird problem with my Galaxy S5 (SM-G901F, kccat6).
The device is boot looping in the "Samsung Galaxy S5 powered by android" screen.
When I turn it on it is about 7 seconds in this screen, turns off, vibrates and turns back on again and continues to loops in this state.
I've already tried flashing the stock rom (odin says pass, went to stock recovery and did a "factory reset"), installed TWRP and reformatted the partitions and tried to install LineageOS (device reboots in the flashing process). I'm not able to flash LineageOS, TWRP gives me sometimes the error "Failed to mount /system (Invalid argument)", I've tried mounting the partition with the "mount" option in TWRP and that seems to work but I get the same problem again.
I've copied the TWRP log file from /tmp/recovery.log: https://pastebin.com/7FX6TtEe
From what I can see the issue seems to be that /system is "Mount_Read_Only", althought I didn't say "keep system read-only" on the first start of TWRP. I've already tried reflashing TWRP a few times.
I'd grateful for any help

Thanks for the answer.
It helped me a bit. When I flash the stock firmware and pit file with odin the device boots up to the "SAMSUNG" screen (blue notification LED and pulsing samsung logo) but then hangs there and doesn't continue. After a while it resets and boots up to this stage and continues to boot loop.
When I enter the stock recovery and perform a "factory reset" and try to boot up the device it's back to the previous stage where it loops in the "Samsung Galaxy S5 powered by android" screen.
Any ideas?

I've tried it with this pit file, but the device just keeps power cycling in the "Samsung Galaxy S5 powered by android" screen. It doesn't even reach the "SAMSUNG" screen. With the pit file from sammobile it does reach the "SAMSUNG" screen but gets stuck then. :/

Try something a bit different - the pit files available may only work with older versions of Android for that device
Try this firmware (if you don't have a premium account Google it - I'm sure you can find it somewhere)
https://www.sammobile.com/firmwares/galaxy-s5/SM-G901F/BAL/download/G901FXXU1BOC4/45987/
With this pit
https://forum.xda-developers.com/attachment.php?attachmentid=3795955&d=1467017826
If it works you can try flashing the correct firmware without the pit
It's probably just a case of trying different things out

I don't have a sammobile premium membership so I got the firmware from: https://simunlockremote.com/galaxy-s-series-firmware/ (G901FXXU1BOC4_G901FBAL1BOC1_BAL).
When I try to flash the firmware with the pit file you recommended me I get the error "SECURE CHECK FAIL : PIT" on my device in the download mode and Odin says fail.
Currently I'm downloading the german version of the 5.0.2 firmware (G901FXXU1BPA2) and I'll try that with the the pit file from sammobile. The download will take quite a while because it's heavily throttled.

After endless hours of fiddling around with various firmwares I have it working now.
I've used:
- firmware: DTM Germany 4.4.4 (PDA: G901FXXU1ANI5 CSC: G901FDTM1AOA1)
https://www.sammobile.com/firmwares/galaxy-s5/SM-G901F/DTM/download/G901FXXU1ANI5/44676/

https://www.sammobile.com/forum/threads/30119-galaxy-S5-G900-and-variants-pit-files
It boots up into android 4.4.4. But when I perform a firmware upgrade with Samsung Kies to 6.0.1 it goes goes back to boot looping. When I try to flash LineageOS or restore a backup in TWRP the device reboots itself while installing in TWRP and starts to boot loop again.

You could be right. I've tried running Antutu Benchmark on the device while it's on battery. It basically crashes instant and the phone reboots. I've tried it while the device is plugged into an outlet with the standard charger and it doesn't crash/randomly reboot.
Never thought somethink like that could cause that, but you've potentially proved me wrong
I'm going to order a replacement battery. Thanks!
I'm completly lost right now.
I bought a new battery but that doesn't seem to solve my problem.
I can flash the 4.4 DTM with PIT and the device boots up. It's super slow and lags, but for the most part it works.
With boot loop I mean the device is stuck in the "Samsung Galaxy S5 powered by android" screen and reboots after some time and gets stuck there again.
Kies: upgrade 4.4 to 6.0.1 => boot loop
Odin: flash 4.4, boot up, flash 6.0.1 => boot loop
Odin: flash 4.4, boot up, flash 6.0.1, flash TWRP, install LOS from TWRP (twrp-3.2.3-0-kccat6) => device restarts while flashing or boot loop
Odin: flash 4.4, boot up, flash 6.0.1 bootloader and modem, flash TWRP, install LOS from TWRP => boot loop
At some point I somehow got it to boot up into LOS 15.1 but in the setup process everything crashed and the device wasn't usable at all. After that the device rebooted itself and got stuck in the LOS boot animation. Another time a achived the same, but after it rebooted itself it got stuck in the "Samsung Galaxy S5 powered by android" screen again.
I appreciate any help thanks

You can try formatting every partition in twrp
Goto wipe
Advance wipe
Format the following
System - data - cache - art/delvik cache - internal storage
Go back & select wipe again but choose option on right hand side (not advanced wipe)
Reboot to recovery
Install from sd card or re-copy rom zips etc back to internal storage
With Linageos are you flashing gapps too?
For lineageos 15.1 use mind the gapps (arm)

I followed your instructions but I'm still stuck. Before I've only installed LOS 15.1, without gapps and nothing else. I've also tried it with the gapps you recommended but that also doesn't work.
I've discovered something weird: I followed this guide to extract the modem and bootloader from the stock firmware: [url]https://forum.xda-developers.com/showpost.php?p=70452245&postcount=2[/URL]
4.4 bootloader + modem (DTM): I can flash LOS in TWRP without a problem (but doesn't boot up, boot loop)
6.0.1 bootloader + modem (DTM): TWRP reboots while flashing
6.0.1 bootloader + modem (DBT): TWRP reboots while flashing
From what I understand from the install instruction for LOS 15.1, the newer bootloader CQJ1 from the original 6.0.1 firmware is required.

Unfortunately I'm not able to do a OTA update. The device downloads an update to android 5, reboots, boots to recovery mode, installs the update, reboots and starts boot looping in the "Samsung Galaxy S5 powered by android" screen. After watching that for about 10 minutes I pull out the battery and try to boot to the stock recovery mode. The device then shows the screen "installing system update 25%". It never goes over 25%. At some point the device reboots itself and continues to boot loop. :\
