Phone bootloops to Samsung logo - Galaxy S 5 Q&A, Help & Troubleshooting

Hi,
I've run into a little problem with my S5.
I have a G900W8, I rooted it with Towelroot and put custom recovery on it, and updated it the baseband and modem to lolipop ones.
Now, the problem is, ANY rom I put on it, the ROM would boot up fine, then after setting it would crash to the Samsung logo and boot up again and bootloop within seconds after starting up again.
In some cases after installing different roms, "process" would stop responding and the rom would crash to the Samsung logo.
If anyone can help, it's much appreciated.

If you update baseband and modem to lollipop I would assume you could only install Lp roms. I would Odin back to stock. Root recovery and go from there

I did that actually, and even with stock lp firmware, the same thing happens! And the all roms I tried after the baseband and modem update were lolipop! Any other ideas?

[Q] Urgent Help Required Please!! GALAXY s4 I9505

Hi Guys,
After rooting my phone, trying different Custom Roms and reverting to stock a couple of times, I now have soft bricked my S4, or at least I hope it's only a soft brick.
I upgraded from JB 4.3 to Kitkat 4.4 and TWRP recovery a couple of months back. I live in Australia and as yet we don't have access to Stock Kitkat 4.4, so I flashed the United Kingdom XXUGNG8 (BTU) firmware. The phone began to lag and a couple of the functions refused to work, so without thinking I attempted to flash back to JB 4.3.........I know, I know you can't do that, but tat the time I was frustrated with it's performance and I didn't think before I acted.
Anyway, first I was unable to enter Recovery mode......nothing worked, the phone would just boot to the error screen. I was able using Odin 3.07, T erase all, flash a .pit file and obtain a "pass".
Get pit for mapping
Firmware update start
RQT close
Res ok
Removed
Remain Port.......0
All threads completed (Success 1/Fail 0)
Then when I attempt to flash a stock rom, it fails every time at "System Write".
I now have discovered that a "Phil's Touch recovery .tar" can be flashed, but nothing else.
When I boot the phone up, it hangs at the Samsung Galaxy S4 iGT9505 screen.
What have I done wrong guys, have I completely corrupted the phone, or is it recoverable? Please Help.
Regards.
You can't revert back to 4.3.
So flash a custom rom or a stock 4.4.2 rom and you will be fine.

Yes thanks for your reply. I re flashed a pit file and stock rom together and it appears to be working fine now.

I9505 rooted but cant install custom recovery

EDIT: Sorted it, flashed TWRP in odin and it worked this time.
I have rooted my i9505 (5.0.1 stock Baseband i9505XXUHOD5) using CF-auto and Odin but I cant install a custom recovery. When I try in odin it says pass but then gets stuck in a loop at reboot. When i go to recovery its still stock and the only way out of the loop is to factory reset abd then try again. It looks like a Vodaphone Germany rom thats been unlocked installed. Any ideas please? I want a custom rom to get rid of the Samsung crap in the background.
Thread can be closed
As you have solved it,like this you open this thread for nothing
And also, CWM and Philz are outdated and out of support(only for this device), always use TWRP[emoji6]

How to unlock note 3 bootloader : Secure download :Enable

On download mode my note 3 shows SECURE DOWNLOAD : ENABLE in blue colour which I guess means my bootloader is locked . Whenever I flash any custom rom like cyanogen mod or any custom kernel I get stuck on kernel is not seandroid enforcing set warranty bit kernel . I'm currently on stock lollipop rom .
so my question is how to unlock note 3 bootloader so I can flash custom rom (I can flash and boot rom darkera but not cyanogenmod or aosp , aokp rom)
And how to remove SECURE DOWNLOAD : ENABLE from download mode
Please Please help
Secure download enable doesn't means locked bootloader. If your phone model is n9005, it unlocked already.

Theres no unlocking for Samsung, you have Odin for that. Flash a custom recovery with it, boot in there and install the custom ROM. Done. There are dozens of manuals for that in here ^^ (Thats the 3rd time I post this one in a row... GUYS, ONE POST IS ENOUGH!)

Hi, I need some help.
I have Note 3 SM-N9005 Lollipop 5.0 stock rom (N9005XXEGBNL8) and rooted with TWRP recovery. I really want Xposed, tried to flash it and got stuck in bootloop, so I tried deodexing my rom, I did it with Joel Droid Lollipop Batch Deodexer, it went well until I tried to install it with TWRP, instant bootloop again, then I tried flashing any custom rom with TWRP and before flashing I always do advanced wipe, but nothing helps, roms doesn't even start installing, my phone just reboots and I'm in a bootloop again, but after flashing rom bootloop is different it doesn't show Samsung logo it just shows Samsung Galaxy Note 3 SM-N9005. So my question is can it be bootloader and if so how can I unlock it? Or is it something entirely different?
Please help...

samsung galaxy note 3 SM-N9005 has been stuck in downloading mode
Actually,i had rooted my device yesterday now, when i am trying to install cutom recovery TWRP on my device it suddenly rebooted and locked at downloadin mode.
Can,anyone suggest me any way to reboot again to normal touchwiz mode
Suggests you flashed the wrong recovery for your model .CHECK
See multiple identical posts .
READ the TWRP thread .
To the phone back to stock, flash the phone with Odin and a stock ROM from Sammobile.com.

SM-N910F Won't boot

Hi,
My SM-N910F wont boot. I have tried to flash a stock rom through Odin, and the flash is successful but when the phone boots up it just says "System UI has stopped" with a black screen.
I messed it up by flashing both modem and bootloader wrongly, then wanting to reset it by flashing stock firmware, but it won't work.
Edit:
I have flashed twrp and managed to factory reset, and it boots now. But now I have another issue, it restarts every 30 seconds, can't even get past set-up.
Edit2:
I have fixed it. I flashed the right modem and a bootloader update and it no longer restarts.
Would appreciate any help.
Thanks.
Help with what?

Flashing G903W with G903F ROMs

I've been trying to load a custom ROM up on this Canadian G903W for a little while with no success. I can get TWRP on with ODIN but once I go to install any ROM available on XDA the phone will not boot. Just hangs at the Samsung logo. I eventually had to boot back to original stock firmware to get it working again.
What am I doing wrong?
Did you both try official LineageOS 17.1?
Same
Same issue mate. The 903W seems to be neglected, I had a hell of a time getting twrp to flash even (turns out all you have to do is stock rom flash first).
I'll see if I can get an eng build and debug the bootloops.
