Root Need help fast. WITHOUT A PHONE

[Tmalcosky18]

I have a droid and i rooted it. put a new rom on it. then my brother was telling me how he got another kernel and was able to speed it up more. so i did that . and now once i did that.. everytime the phone shuts off.. it will go to the M screen and then constantly reset. 3 times i have been able to get into the recovery mode and make the phone usable again but i have been trying for over 8 hours to figure out how to try to unroot it without starting it up . can someone please tell me!?

you may be able to just flash a different kernel that works

How to Flash a custom kernel with SPRecovery




1.) Download the kernel
2.) Place the file in the root of your sdcard.(Not in any folder just on the sd card.)
3.) Rename the kernel to update.zip. Be sure that you are only naming it update.zip. Windows often does not show file extensions and you will end up with files named update.zip.zip. Renaming files with Astro File Manager once they are on your sd card is a good solution to this.
4.) Power off your droid
5.) Boot into recovery by holding X while powering on the phone
6.) Perform a nandroid backup (always sound practice although this is not required. Its actually not necessary at all if you have a kernel that you know works well somewhere on your sdcard.)
7.) Click on install (Note you can use the volume rocker to navigate and the camera button to select.)
8.) Press allow update.zip Installation
9.) Press Install /sdcard/update.zip (deprecated)
10.) When the install is complete use the power button to go back to the main menu
11.) Reboot
