[Q] Questions about rooted phone

I currently have a rooted phone with the following:
ROM: GorillaSense-DHD-MT4G-v2.2.3
Radio: 26.03.02.26_M
S-Off
Hboot: 0.85.2007
ClockWork Mod 3.0.2.4
After I got permanent S-Off I can only boot into recovery mode through CWM Reboot into Recovery. I have tried uninstalling with Titanium and reinstalling through the Market but it didn't fix the problem. Anyone know what I can do to fix this?
Another question. Do I need to upgrade to a newer ROM to fix the ClientLogin vulnerability mentioned at engadget or does 'fixed on the server side' mean that the security tokens (or whatever those things are) handed out can't be spoofed by a server in a wireless network?

a few ways to boot into recovery
1)
turn off the phone > hold the power button down along with the volume down rocker
2)
from the terminal emulator
Code:
$ su
# reboot recovery
3) from the CMD prompt via ADB
Code:
c:\<file_name>adb reboot recovery
or
Code:
c:\<file_name> adb shell
# reboot recovery
as far as your security issues i dunno. I do not use public access wifi routers.
by fixed on the server side, that means it was a problem with Google's servers, not your phones. Google has fixed it.

I should have mentioned that I can't get into recovery mode using the volume down + power button method. Do you know how I can get that functionality back?
Do methods 2 and 3 require the OS to launch? I am concerned that I won't be able to get into recovery mode if the OS is not available. Is this a valid concern?

What happens when you do it? You don't have "recovery" in menu? Then choose "Fastboot", and there'll be "recovery".

Nothing happens. It boots normally with my finger is holding down the volume down button. The phone only boots into the recovery menu when I select the recovery option in Clockwork Mod.

Go to "settings>applications>development" and make sure fastboot is UNCHECKED. fastboot will disable booting into recovery mode when enabled...hence...only CWM gets you there.
UNCHECK fastboot then turn off your phone....you should be able to use the 2 button combo
::thanks?did i help?::

[Q] Can't make CWM Rcovery permanent

I followed this post to root my Nexus 7 step by step. But when I came to
5. Make CWM Permanent -
1. Boot into recovery
2. Go to Mounts and Storage
3. Mount /System
4. Type in Terminal
adb shell
cd /system
mv recovery-from-boot.p recovery-from-boot.bak
I got a error says there is no file fecovery-from-boot.p. And I coundn't make the CWM permanent. Somebody know this?
(Forgive my pool English, Thank you. )
Do you have to flash recovery every time before booting into it?

yes, that is a way to enter the CWM.
And use "adb reboot recovery" when the device is power on can enter the CWM too.
Just install it through rom manager, enter recovery, when you exit it will ask to patch it, say yes and you're done.

I found that flashing it twice in a row made it stick...

If running that works then it is permanent.

But when I normally enter the fastboot and then choose enter recovery, the device stunked. Is there another to enter the recovery mode?

[Q]how can i enter ad recovery using adb commands ? (without using vol. buttons)

how can i enter ad recovery using adb commands ? (without using vol. buttons)
If you're on MAGLDR, I don't think it's possible.
If you insist, this is the command:
adb reboot recovery
and in clk?
It's the same command in cLK, because it's still adb.
What i mean, in which bootloader is it possible?
Sent from my HTC Sensation Z710e using xda premium
It's only possible in cLK, on MAGLDR your phone will be normally rebooted and not into recovery.

This was not working for me for some reason (probably user error). I plugged my phone into my computer, opened a command prompt to the Android SDK and typed:
Code:
adb reboot recovery

Recovery/2nd bootloader on kindle fire hd

Hi,
because I have unsufficient rights to post in dev section, I wanted to start a new thread about the 2nd bootloader.
I just followed the howto and I can confirm it worked fine. I did not even need a factory cable.
http://forum.xda-developers.com/showthread.php?t=2128848
Thank you for that!
First question: Is it normal, that from pressing the voldown and turning blue, it need about 3 mins to boot into TWRP?
thanks

Hello, I don't have rights for devs thread too so I'm happy to see this thread on. I installed 2nd recovery following the Hash's instructions and end happy and without any problems. And for me just take 30 seconds or less to go to recovery.

Change to the directory that has the files. If th file were on c:\ change to it then run the commands
this is what i did
I am not taking credit for this. this is just what i did on windows 7 with Android SDK already installed, adb mode already enabled on kindle

.... well, I just followed steps 1-4 and after unsucessfully trying step 5 with an usual usb cable I rebooted the kindle via adb with:
adb shell su -c "reboot bootloader"
... and the fastboot screen showed up.
After a working
fastboot -i 0x1949 getvar product
I continued with step 5.
