Still looking for some help! anyone know how to?

Flashing recovery from ODIN has failed for me and a few others too, rooting with CF Auto Root and then using TWRP Manager from the Play Store was how I managed to get TWRP recovery installed

it didn't resolve maybe someone that had same issue and successfully resolved could share their thoughts?

[Q] Help Urgent! Custom Recovery Issues.

Hello, my phone has a rom installed that will not boot up. I use flashify to flash the custom recovery to backup/restore/flash files. Now that I cannot boot up my phone, I cannot use flashify. Odin will not stick TWRP to my phone, and I cannot get adb to recognize my device. I really need some help to get the custom recovery to stick so I can restore my backup. Please help if anyone knows how to fix my problem, thanks in advance!
Nvm, I fixed the problem. For anybody else having the same issues, all you have to do is download the stock firmware and install it through odin. Stock firmware can be found here: http://www.sammobile.com/firmwares/3/?download=27867

[Q] Unable to install Custom Recovery

Hello,
I am facing weird problem, I am not able to install custom recovery, I have tried almost everything.. nothing helped.
I am still getting stock recovery..I have tried to flash it via Odin, via some apps, unfortunatelly nothing worked.
My Samsung Galaxy S4 i9505 is running KK 4.4.2.
Any idea?
Thank you.
I had this problem too. keep flashing cwm recovery through the app (needs root I think). and reboot into recovery, once you get cwm you can flash a custom rom or another recovery like twpr or philz.
s4 i9505 stock KK
I have that problem too. I have stock KK 4.4.2 XXUGNG8 updatet ota. When i try to flash flashable zip file cwm of philz or twpr i get some error like:
E:footer bad
Mds check
Something like that and cant flash it. I tryed with odin but no luck. Does anyone have same problem?
I had this problem to
I fixed it by checking te root options.
If u use a root app, make sure it gives always root acces.
After this, install a custom recovery rom
After that you'll have no problem installing a custom ROM
Good luck.

But my phone is not rooted, its new, with stock recovery, knox 0x0 still....
Have any idea?
Ok, but what if my phone is not rooted, how am I supposed to root it? When I tried CF-Auto-Root my phone started to reboot randomly during the phone call.
I have found one solution, but I am not sure if it works, it says that if you are flashing custom recovery via odin, you have to take out the battery after the flash is done so you won't allow your phone to restart and rewrite the recovery back to stock. Have anyone heard about it?
No, no idea.
Thats crappy.
Only know how I fixed it

Just uncheck auto-reboot before you flash the recovery. That will fix your problem.
I have tried it, but it didn't help still looking for solution, is there any way how to RENAME RECOVERY RESTORE FILES so I can finally flash custom recovery? (non-rooted phone)
OK, so the solution that worked was simple and I have already mentioned it, you have to take out you battery on samsung galaxy s4 logo, before it reboots.
My solution
Hi I had the same problem too,
I solved it this way: (My phone was rooted)
Download the .zip file from the recovery you want (I used CWM 6.0.4.7)
Next download 'SGS4 flasher' from the playstore.
SGS4 flasher needs root (I think) andyou can flash your recovery through that app.
Next boot into the recovery and you should probably end up in your custom revovery every time now.
If you don't end up in your custom recovery, download ROM manager and then choose the option boot into recovery.
This worked for me at least :laugh:

[Q] Need advice for recovery flash

So far, all i've been able to do is root my s4 via towelroot. I want to flash cwm but the flashimagegui app tells me that my device isn't supported. The only other way i know to flash cwm is through odin, but then I found out that my device might have a locked bootloader.
Could anybody explain to me if I would be able to get cwm and cm11 working on this phone? It's running 4.4.2 build :KOT49H.I337UCUFNC1
I apologize if these questions have already been answered, any help would be greatly appreciated however.
Thanks
You have a locked bootloader which prevents the stock kernel and recovery from being replaced. So, cwm will not work. Only working recovery is safestrap. More info http://forum.xda-developers.com/showthread.php?t=2616221

Can't Flash Custom Recovery Twrp via Odin or Apps

Hi everyone.
I have a Verizon Samsung Galaxy S5 G900V rooted on OA8. I believe my bootloader isn't locked since I was able to do this.
When I try to flash TWRP via Odin it fails. When I try via an app, it crashes and I have to recover by flashing stock partitions.
When using Odin, I get am error on my phone screen similar to secure check fail and magicode fail.
I haven't tried CWM installer because I want TWRP.
The apps I've tried to flash with are Flashify and TWRP Manager. I haven't tried Rashr yet.
Any help would be greatly appreciated. If you need more I go I'll get it and update.Thanks!
You believe wrong, it is locked.

Note 3 will not accept new firmware install

Hi,
I have searched these forums and i am surprised to see that i am possibly the only one with this issue. I have previously rooted and flashed custom roms on my note 3 (SM-N9005) without issue.
The last flash was back to stock 5.0. Now when i try to flash recovery with Odin it does pass then i reboot manually into recovery and i either get boot error odin mode or it just reboots. When i flash a stock firmware the phone does not wipe even if wipe partition in odin is ticked.
There are a few roms i'd love to try out but i'm stuck on the current stock as i cannot flash recovery on my device. Any help would be greatly appreciated.
Thanks
It looks like you flashed something wrong which mada all these problems
Try to use kingroot or any other app for rooting other than the traditional method
Root it and use rashr flash tool from play store to install recovery
