Warning about using CWM.zip (temporary / Touch recovery) to root or flash any file
Note : This is referance only to CWM.zip , which is temporary/touch recovery commonly used to root device. Other cwm recoveries which are permanent and getting along with custom kernels are safe.

I checked the recovery binary using "strings" to see if it was a "dangerous" or "safe" one.

adodd@quadmonkey:~/Documents/galaxynote/tmp/sbin$ strings recovery |grep discard
warning: %s: Wipe via secure discard failed, used discard instead
discard_after_textures
discard_before_textures
Can't discard critical data on CRC error.
discard
discard

The key here is that warning - if that string is present in a binary, it is most likely a dangerous one. Since there have been multiple reports of bricks associated with this zip file, I've sent the moderators a report that this release should be removed.

DON'T USE CWM.zip (touch recovery) at all

Present option to root ICS ROM is

So present option for rooting is - You can select any of one.

1. Short, easy - requires to reset counter

-Download Odin (.tar) version of custom kernel like Notecore, Speedmod, CF root kernel Or other any with same function.
-Flash it using PC odin for PDA tab.
-You will get exclamation mark and raised counter, which can be reset with Triangle Away

2. Long, No raised couter OR Exclamation mark
-Downgrade to Rootable GB ROM and Root it. OR Download This pre rooted GB ROM and flash using PC Odin
-Wipe cache, data and delvic cache from recovery
-Install Mobile Odin Pro
-Copy ICS ROM file in .tar (you want to flash) to Internal SD card (recommended, but you can have it on EXT too)
-Copy one of custom Kernel in .tar file e.g.Notecore, Speedmod, CF root kernel Or other any with same function.
-Open Mobile Odin Pro
-select open file
-Point to ROM file you have copied
-All fiels will popup and feel automatically
-select kernel and point to custom kernel file you have copied
Flash.
Done!

Damn !!! just when you think we're making progress and things and things are getting 'safer' something like this happens

Good find well done !!

Do we have any working methods for rooting the latest 4.0.4 Stock ROMS at the moment ?

Or do we need to wait till a fixed CWM is available ?

I think available option is
-Flashing custom kernel with PC odin, and then reseting counter with triangle away
-switching Rooted ROM to ICS with Mobile odin pro

Or it is same unsafe like using backup/restore/wipe function with CWM.zip

backup?! is backup also dangerous on an effected kernel? I understand it writes the backup image ,but that's usually to the external SD card which is unaffected by the bug due to different hardware

are you sure a backup is as dangerous as a restore? I backup all the time on an affected kernel

How about mobile odin. Is it safe.

I'm on anidroid rom with anidroid kernel and recovery.


Will I brick when I wipe in cwm using this setup?

Yes, Mobile Odin should be safe if you read what Dr.Ketan said.

No, you are safe. From everything I am reading, this is different.

Damn it. I used to flash SpeedMod kernel from "CWM.zip" to root ICS.
But only kernels not ROMs or never used it to factory reset or backup / restore.


From now on I'll use only PC Odin.

edit...

I just checked that Note has 12 partitions and one of those is kernel partition. And last thing I want is corrupt kernel partition.

As Dr Ketan and Entropy told, stay away from "CWM.zip"

This is really weird. Ive been using this cwm to flash ics and gb and my phone does have the emmc bug. I made this like 6 or 7 times and had no problem at all... o.o maybe im just lucky
