[Help] Unable to boot into recovery

---

Hi all,

so I tried to flash the latest CM9 Nightly for the first time.

Unlocking and rooting worked fine. I then tried to install the latest CWM Recovery using the heimdall method from my Mac using this guide:
http://wiki.cyanogenmod.com/wiki/Sam...l_Update_Guide

That didn't work because heimdall seems to have a bug, it was unable to connect. I then booted my Tab and flashed CMW Recovery using ROM Manager. It just had an option for Samsung Galaxy Tab 10.1, not for the 10.1v. I guess that's where I made my mistake, because I tried the Recovery for the 10.1.

I then tried to install the latest CM9 nightly, which failed with the error message

assert failed: getprop("ro.product.device") == "p3" || getprop("ro.build.product") == "p3"

I figured that was because I had used the wrong recovery, so later at night, when I had access to a Windows PC, I tried flashing the recovery.tar.md5 using Odin 1.85. It gives me a success message, and I am able to do a normal reboot.

When I do

adb shell
su
reboot recovery

or when I use ROM Manager to boot into recovery, the Tab reboots and I see a green Android with an Exclamation mark on a yellow triangle. The Tab doesn't respond to any Volume UP/DOWN keypresses. It just stays in that mode for a couple of minutes, and then does a normal reboot.

From that point on, I can do normal reboots and they work just fine, but I just can't get into a working recovery.

My best guess would be that installing the 10.1 Recovery messed up my partition table or something like that.

Any ideas how I should continue?

Thanks a lot,
amiuhle

Use ODIN

- download the latest recovery from here http://droidbasement.com/db-blog/?p=2668 for the p3
- extract the recovery.img and flash it via fastboot: fastboot flash recovery recovery.img

that should do the trick

Same thing, all I get is the android with the exclamation mark when I try to boot into recovery. Do you think I should reflash Bootloader, Phone and PDA to stock using Odin using those files:

?

Thanks!

I've got the same error long time ago.
Use Odin, flash the tab to stock. Root it, install recovery and then be happy with CM9

Are you sure it's correctly unlocked? Otherwise start over indeed with the odin files. Make sure you take the unlocked bootloader. There's only one

If you
-have root
.have unlocked bootloader

Just install rom manager from play store and flash recovery with rom manager (you will find only galaxy tab 10.1 option)

Rom manger will create recovery partition and you will have a 4.0.0.4 recovery than you will be able to flash the 5.5.04 recovery with odin or fastboot
