Phone stuck on cmod screen even after flashing stock firmware and corrupt cache - Samsung Galaxy Express SGH-I437 Questions & Answer

My galaxy express i437 ATT was stuck on cmod boot screen and won't start I tried deleting cache via cwm recovery but it's also corrupt says can't mount sd card etc.
After all I tried flashing stock firmware in it via ODIN and it showed pass, but when I booted back up the cmod screen was still there even after flashing stock rom. I don't know what's wrong here.
So I have two problems here cmod boot screen logo and can't mount sd card in cwm recovery. Any help will be much appreciated.

[Q] Apparently I screwed up. SOLVED!

I have my nook rooted and all of that and for some reason I decided to wipe the thing clean in CWM recovery and now it won't boot to anything unless I boot from SD. I've tried booting into a rom from SD and installing CWM recovery again through rom manager and it says that is has flashed successfully but when I tell it to restart it goes back to the rom on the SD of course, so I tried taking the SD out and holding down the N and booting into recovery and I get nothing no loading screen no nothing, am I not getting CWM installed? Is there a zip I can flash from CWM on SD to flash it?
EDIT!!!!! If i had remembered to format the right things then I wouldn't have had an issue.
If you are having the problem described above remember to format BOOT, System, and Data. And then flash your rom.

Thank you I don't know what I was thinking, if I had just formated the right things it would have worked just fine, I am a tard sometimes.

Virgin Mobile S4 stuck on boot Logo HELP

I'm not sure why i can't get it working but i was flashing back to stock rom. I have the correct rom and everything flashes fine on odin. I am unable to reboot to recovery. it says its loading and goes to black screen, and tries to boot to OS again. I tried flashing twrp with odin and same thing. I flashed the stock rom multiple times and it just won't boot. I even used Kies to flash it to stock rom and it was successful however stuck at boot logo again. The one thing i didnt do was wipe data/cache etc before flashing to stock rom but every tutorial i seen doesnt state to do it before the flash anyway. Has anyone ran into this problem before?
How are you able to get into download mode to flash rom but not be able to go into recovery? I had this issue once with my note 2 and went into recovery and wiped data and rebooted successfully....

S4 stuck on boot screen, can't go into recovery mode

So, i have the Galaxy S4 i9505 and last night rooted it with Odin 3.07 and placed CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5. I then decided to flash on a ROM so put on WanamLite. All worked fine. Today i wanted a new custom ROM so downloaded PACMAN AIO Nightlies. I went into recovery mode, wiped all data, cache, dalvik cache and then went into install zip from sdcard and chose the zip file. It seemed to be installing and since then has been stuck on the Samsung boot screen. I have tried to get back into recovery mode but it won't get into it. I managed to now get into recovery mode but it isn't Clockwork Mod Recovery any longer it is the Android one. I went into this, wiped everything and tried to boot but it still remains stuck on the samsung boot screen. SOMEBODY PLEASE HELP!!!
NOW i went into download mode, used odin to flash the clockwork recovery mod into my phone, now i can get into clockwork recovery mode, but i cant flash on any roms they keep failing and my phone wont boot, please please help me

[Q] CWM disapeared, boot loop, only have access to android system recovery

Hi guys
(SM-N9005)
So yesterday I had liquid smooth rom installed for the past month or so (I have been trying a variety of roms for the last year or so) and I was getting some bugs occuring and decided to put a new rom on.
I booted into recovery, did the normal backup, factory restore, clear cache and dalvik, installed the rom and restarted my phone. It then went into a boot loop.
At this point I assumed it was no biggy, so I just went back to recovery and chose to restore with the backup... except it wouldnt. it couldnt recognise the file it had just made.
So I then coppied some previous backups to the external micro sd, stuck the micro sd card in, booted in recovery and tried to recover with them... couldnt recognise them.
I also noticed that when trying to reboot, it came up saying that I didn't have root access... even though I certainly have for the past year.
I tried flashing an updated version of superuser as that was the suggested method on some forum - didnt help the situation.
Now when my phone boot loops, it goes straight to android system recovery <3e> and nolonger have access to CWM
No idea what to do, and my uni work greatly depends on me having access to my phone :/
Any help would be greatly appreciated
my baseband version is LRX21V.N9005XXUGBOB6
