CWM Recovery not booting.

Hi guys. I have used Odin to send the recovery to the Tab and when I go to boot into recovery all I get is stock recovery. Odin says successful upload etc but I cannot get CWM to load up.
I am GT-P3110 on stock 4.1.1
Any idea?

Bootlooped and cannot use TWRecovery

Hello,
My nexus 5 is currently stuck in a bootloop and TWR is asking for a password to decrypt my data and wipe cache/dalvik. Is there anything i can do to get it out of the loop or is my phone dead?
Thanks for reading, any advice is greatly appreciated.
Does your computer recognizing your device? Can you go into bootloader,if yes,try to go back to stock rom,and flash stock recovery.

[Q] Boot loop after factory reset, please help

Nexus 5, 4.4.2, stock-rom, rooted.
It was using Franco kernel r51.
I used the Franco Kernel Updater to restore the stock kernel 4.4.2.
It went boot-looping ...
I went to Recovery mode, reset to factory ...
Finished, reboot now
It was still boot-looping ...
I reset to factory once again, and it is still boot-looping ...
Anyone can help?
Thanks.

Don't use Toolkits for that.

[Q] Restore Nexus 5 to stock

Dear friends,
Today I bought a used nexus 5 for a little money. The only problem with it is that it wont boot anything because the seller wiped all data (inc. OS) which he thought was a factory reset. He was really stressed this happened and sold me the phone for even less. The only thing he did in the past was install a recovery mode.
My question:
How can I restore the phone to stock ROM? Currently there is no ROM installed. Everything is wiped.
What I already did:
- Download the 4.4.3 (KTU84M) version.
Use fastboot and flash factory image.
Refer sticky for guide.

Hey,
Thanks for the answer. I did these steps. Fastbooted hammerhead-ktu84m and everything works. According to devs.google I should relock bootloader. Is it neccesary?

Restoring Nexus 5 to stock: will it replace TWRP?

Hi all,
I have a Nexus 5 that I'm trying to return to stock. I'd like to keep the bootloader unlocked, however. If I follow the instructions here (minus the bootloader lock part): https://developers.google.com/android/nexus/images will I be all good to go with a completely wiped, good-as-new phone? Also, will this overwrite TWRP, which I currently have on the phone?
If you follow the instructions and flash everything, yes it'll go back to stock and replace twrp with stock recovery as well
If you flash the img files individually, you don't have to flash the recovery img if you want to keep twrp tho

Thanks! I think I'll just do that, but I'll keep the bootloader unlocked in case I need to flash more things later.

If you're flashing stock, remember there's a built-in behaviour that checks for stock recovery: if it's not there, it will overwrite whatever is there (twrp, in this case) with stock recovery, on every reboot.
You'll need to take care of this if you want a stock+twrp permanent combo.

After looking at this guide, it says that you need to do a factory reset in the stock recovery after flashing all the images. Is this outdated information?

Yep, next time you're on stock checkout /system/install-recovery.sh and /system/recovery-from-boot.p files.
