Default AT&T S4 can not get into recovery mode (MF3)

Phone information:
Model number: SAMSUNG-SGH-I337
Android version: 4.2.2
Baseband version: I337UCUAMF3
Kernel version 3.4.0-812098

Unlocked, Rooted with 3rd party software, show "samsung custom” every time when turned it on, then AT&T logo...

Want flash "danvdh google edition 4.4.2 ROM", and already transfer it to sd card.

Installed rom manager. Want to backup rom before flash, can not do it. When select "backup curent rom", restart, top left showed “recovery booting”, then saw a robot laid down with "!", showed "no command" under the robot. up showed:
#manual mode#
-- Applying muli-cs ...
applied the csc code: att
successfully applied multi-csc.

Top left showed some like
android system recovery <3e>
reboot system now
apply update from cache.

When select reboot, showed "error" first, then reboot.

Please give some suggestion, Many thanks!!!

You can't use clockwork mod with MF3. You have to use safestrap. Did you follow any if the walkthroughs?

Unfortunately the Manual is named READ-READ-READ--

There are several threads in General and Q&A that will cover all you need to know about SafeStrap

Best to read them all as no one thread has everything--

Follow these closely or you can brick

Personally I read the OP pages and first/last 20 pages, or more, of any new rom etc I want to flash

People seriously need to start reading -.- all the questions on here are referring to not being able to get into recovery when they are on mk2 and mf3. It's all over stating there's no custom recovery for them yet we get posts like this -.- just read. It's not that hard.
