[Q] CWM Signature Verification Error?

When I try to flash CWM, I get a signature verification fail error. I replaced the recovery binary but it still won't work.
I am using this rom: http://forum.xda-developers.com/showthread.php?t=1139326
Does anyone know a fix for this?

The link is broken... Have tried to Odin one of Dr Honk's kernels?

The link is working again. It looks like that kernel needs adb to access recovery, which I haven't been able to get to work. Do you have any other ideas?

I'm not sure what you mean by this. Are you just trying to get it into recovery? If so, do you have the Android software developer kit (SDK) installed? The SDK includes the adb binary. Download it, install it, then open a command prompt, cd to the 'platform-tools' directory where the SDK installed, insure your phone is on & plugged in via USB, and issues the command: adb reboot recovery.
If I'm off-base with what you're trying to accomplish, my apologies.

Don't use a KFx rom, the KF1 and KF2 versions of Gingerbread were really buggy and will give you more trouble than they're worth. You're better off flashing Octane, Valhalla or ICBINB which get updated frequently.

Which also means that you need to flash a KG4 leak or newer for the proper GB bootloaders. If not, you'll get a rainbow screen.

Similar Problem
Hey Guys,
I had a similar problem. I am using Fire Expert to overwrite the new recovery to the \system\bin folder. However, I realized my mistake was that I did not mount as r/w. After I did that though and I held the volume up, down and power, I stay stuck at the initial splash screen and can't go into the stock recovery screen. I can't boot regularly either; I have to Odin recover. Any help would be greatly appreciated.
Thanks!

Overwriting the old recovery and putting the update.zip file on the sdcard for CWM Final was for Froyo ROMs only, not Gingerbread (GB) ones. What ROM are you currently on?
In order to get into recovery since flashing the GB boot loaders I have to:
Power off the phone
Hold down Volume Up, Volume Down, and the Power button
When the Galaxy S screen comes on, wait a second, it'll get a tad bit brighter. When that happens let go of only the Power button
Wait a few seconds and you should be in recovery
Sounds like you might be a bit goofed at this point, though. If you were on GB before I'd suggest using one of the ROMs in bhundven's The KJ6 Heimdall One-Click Collection. The last one in the list will also give you root, CWM, and voodoo lagfix.

Hey. Thanks for the quick reply.
I am currently on Froyo, Kernal version 2.6.32.9.

Weird. All you should have to do is put the updated recovery in /system/bin & put the update.zip on the root of the sdcard.
What is the current state of the phone? I know in the previous post you said you would have to use ODIN to recover. Did you do that?

Yes I did use Odin to recover. I did it following the link provided in the sgs4g 10 commandments. This is the second time I recovered. After I recovered he first time, I tried the process again and the same thing happened: stuck at the initial splash screen.

Just wondering if your phone is currently working or not. I wasn't sure given that you reflashed with ODIN.

Yes everything is fine right now. Lucky all of my settings and apps were still there after following that tutorial.
Perhaps file expert doesn't work?

I've not used it but if it allows you to mount /system read/write, then it should work fine as long as you're putting the 'recovery' file in /system/bin & the update.zip on the root of the sdcard.
If you try it again then reboot into recovery, what happens?

Soft-Bricking Phone Each Time I Flash

AT&T replaced my Infuse (which I was running JB and before that ICS), so I have a brand new phone.
Came stock with G 2.3.6.
I was able to flash jscott30 2.3.6 Gingerbread with root and CWM recovery option - link below. I chose option C. Phone is running great.
http://forum.xda-developers.com/showthread.php?t=1613523
However, when I try to upgrade to a custom ICS or JB rom (doesn't matter which one) from CWM, the phone soft-bricks - meaning when it resets it's either stuck in Samsung boot loop or that crashed recovery loop.
I have to reflash in download mode to the link above, which thankfully works!
Bottom line - I can't flash any ICS or JB and can't figure out what the deal is. I had no problems flashing before with my old Infuse.
I'm clearly doing something wrong - any ideas? I know I'm not providing a lot of info, but I'm following each flash instruction to the letter (in each OP).
Thanks for any insight!
I don't want to wait for Samsung to upgrade to ICS - if they ever do.

I know it might be a dumb awnser/reply. But did u happen to pull battery out and reflash after it froze? Sometimes that helps. If u have there is nothing wrong from starting back from the start.. cm9 I use for my ICS boot loaderz and then I try whatever else I want. But I always start from. Ginger bread to entropy cm9

Yes, I've tried many different ROMs. Each fails. So weird.

Which CWM do you have. I know that after I flashed the rooted GB version, I then flashed the Heimdall ICS recovery and CWM went to blue version. Then very easy to install ROMs.

There shouldn't be any need to manually install CWM, as the ROM zips have the udated CWM built into them. Since you're coming from GB, the first reboot after installing ICS or JB, should boot you into the new BLUE CWM, after which you may need to format System, and flash again. Also, have you removed your External SD card before flashing? That's caused problems for some people.

My concern is that he said he flashed ICS but still has red CWM. I suggested Heimdall ICS recovery to get him to blue. I am relatively new but that is what I had to do to get ICS on the phone. But I am sure that there are other methods too.

Yep - did the Heimdall and it pushed me to blue CWM. I'm good now!
Just flashed ParanoidAndroid ICS and it's working.

Odd. Never ran into that issue yet, and, as such, didn't notice that there was a Heimdall ICS one-click kernel floating about. Great advice.

Galaxy Tab 2 7.0 not booting

So I have this Samsung Galaxy Tab 2 7.0, GT-P3100 with Jellybeans 4.1.2. I recently rooted it using Kingroot. It worked fine until I tried installing a custom kernel. I installed unofficial miui v5.4 using CVM Recovery v6.0.7 I think. I clicked install from sd card and installed the .zip file. It said installed after a few mind. I then clicked reboot device now. It started booting and showed a new boot image, which I thought was normal. But the image wasn't fitting in the screen. I waited full 30 mins and it stayed there, a light coming and going as a logo. Nothing happened, so I pressed the key combination of power button + volume up button for 5 seconds and it started again, showing the new symbol. It has not booted after an hour and half.
Please help, I don't know what to do.

So I think you flashed a incompatible Rom on your tab 2, well the only way to get it back booting is to try restoring it back to stock firmware, just Google how to restore tab 2 to stock, and follow the video on the channel droid cheats but yeah if you have got pretty fast internet and don't want to spend entire life downloading that 1GB file go the general discussion of the tab 2 7.0 forum here and scroll down you will find a thread named fast download link stock firmware I think it should be something like that and download the one made for p3100, want more help comment below

hello sir,
i know how to solve your problem.
the problem you are facing is a boot loop .i.e you get stuck in the boot logo
and your device never goes further.
the common reason is not clearing dalvik cache before flashing a new rom in recovery.
so now solve this problem follow these steps.
1. charge your device fully and go to recovery.
2. do the following-
do a factory data reset.
clear cache and go to advanced and clear dalvik cache.
now flash the kernel and rom and the gapps(if you have).
now reboot and see you will go through the boot logo .
HURRAY YOU HAVE SUCCESSFULLY FLASHED YOUR NEW ROM
NOTE: all the steps above are only to practice in CWM Recovery.
if you still have any problems let mw know.
thanks
