soething like this also happened to me when i tried to flash cm11 to my xperia sola it was because the kernel i was using was not supporting the ROM once i "fastboot flash boot boot.img" , boot.img given in the zip folder i was able to flash the new ROM. Best of luck

Did you flash the boot.img over pc or on the phone?

I support. This seems like a boot.img problem. Try to make it via PC while the phone is in fastboot mode.

This is for a galaxy s3, would download/odin mode qualify as a fastboot mode? :S

I tried flashing boot.img in recovery, it failed. Anything else? :/

Any other suggestions would be helpful

I would recommend using the latest twrp. I find it much more reliable than CWM. Just my two cents.

Make a flash able zip for boot.img.
.img cannot be flashed through custom recoveries. .
Only zip file can be flashed.

I used TRWP and compressed the boot.img into a zip to flash and attempted it but I get a failed message.... Should I just scrap it throw away the phone at this point? Nothing seems to work...

No boot or recovery img

Can someone help? I can't get into clockworkmod recovery mode.
Currently on nscollab 1.0.4

Make sure you have newest version by flashing through ROM manager.
Sent from my Nexus S using XDA App
He can't boot, therefor can't use ROM manager. Flash recovery.img from fastboot. You can find CWM recovery images here: http://forum.xda-developers.com/showthread.php?t=988686
If you don't know how to use fastboot and flash from it, just search xda, and you'll find many guides ...
Good luck!

Sorry, I'm a noob. Didn't see missing boot img in subject. Had problem flashing with ROM manager before until I updated Clockwork mod recovery. Thought it was similar problem. Lol. Duh.

How to flash Asus 4.1.1 firmware

I am currently on Zeus 4.0 and do not quite understand how I can flash the firmware from the Asus site. Can I simply flash the file through TWRP?
Thanks in advance.

You can,but if you are still on 9.4.5.26 bootloader i would recommend you to use the NvFlash tool first (see the Development forum for nvflash).
Already done. Thought those files might come in handy one day.

Try this one http://forum.xda-developers.com/showthread.php?t=2507672. I guess you have a defective search button
-Edit- Doesn`t boot sorry bro.
TWRP is reported to be working from here http://techerrata.com/browse/twrp2/hammerhead, choose the latest 2.6.3.2 version and flash in fastboot;
Or this http://forum.xda-developers.com/showthread.php?p=47108907

Great app but this isn't an official one.
The XDA thread has been closed and there's no update on Google Play for 2 months.
I don't know if jmz still has other projects... Flashify is also a great app to directly flash the img files without a PC.
I heard that
Code:
fastboot flash recovery TWRP.img
works pretty well...

No need to use Fastboot if you already have a recovery to flash with.

It doesn't hurt to know all the options and procedures. Actually OP would have already known this if he hadn't used a toolkit to root in the first place
-1 for toolkits
But yes, options are:
Fastboot flash img
recovery install zip
Flashify flash img
Thanks to all for the help suggestions , but yeah I used a tool kit which means I don't know how to do it manually that's why I asked for the easiest way to update .

It would be good to learn how to do it manually. It's really pretty easy. And you'll know your phone better and know how to do things yourself.

Stock recovery?

If I root (towel root) install custom recovery then unroot and factory reset will I have stock recovery back?
Sent from my Nexus 5 using XDA Free mobile app
Sent from my Nexus 5 using XDA Free mobile app
no, factory resets only wipe your user data, they dont magically reinstall software. but you will after you.. a. flash the factory img, or b. flash the stock recovery via fastboot.
all info and guides are linked in my signature. Lots of reading but lots to learn.

You could extract the recovery.img from the stock rom and flash it
Just discovered flashify oh man its amazing
