[General Questions and Answers] manocao:
hi, i replaced recovery partition with wrong cwm recovery.img file and now i can't get into recovery mode, i didn't do previous backup because i did't know how to do it, but now i know...

could some W655 owner perform these steps to backup the recovery partition? (it will not take you more than 5 minutes)

(phone must be rooted with superuser rights, sdcard inserted)

-connect phone to pc (check usb debug is enabled in phone notifications)

-install w655 windows drivers (attached file, it includes ALL drivers needed for w655: in windows, in recovery mode and in bootloader fastboot mode)

-extract w655.rar (attached file) to c:\

-open console (go start > run > type cmd and hit Enter) and then type (hit Enter at the end of every line):

c:

cd\

cd w655

adb shell

su (remember to accept superuser request on phone)

cat proc/mtd

-then it will show something like this:

dev: size erasesize name

mtd0: 000a0000 00020000 "misc"

mtd1: 00480000 00020000 "recovery"

mtd2: 00300000 00020000 "boot"

mtd3: 0fa00000 00020000 "system"

mtd4: 02800000 00020000 "cache"

mtd5: 093a0000 00020000 "userdata"

-see what mtd number is "recovery" partition, then type (hit Enter at the end of the line):

dd if=/dev/mtd/mtd$ of=/sdcard/recovery.img bs=4096

(replace $ by the number of "recovery" partition, in the example above recovery partition is mtd1, then you should type: dd if=/dev/mtd/mtd1 of=/sdcard/recovery.img bs=4096)

-then recovery.img will be saved into sdcard (you can now close the black window)

please upload and send me link for recovery.img or attach it in this thread

thanks 4 all

edit: then i'll try to build CWM recovery.img for our W655 with ClockworkMod Recovery Builder

in the w655 extracted folder you also got fastboot, with which you can perform many actions (phone must be root):

get into bootloader mode with anreboot app from phone or switch on the phone pressing VOLUME DOWN and POWER keys at the same time until you see "fastboot....." on screen

after drivers installed (included in this thread) run cmd and type (command info between brackets, don't type the brackets and what is inside):

c:

cd\

cd w655

fastboot devices (shows phone hardware info)

fastboot boot recovery.img (loads an image and boots into it, not permanent)

fastboot erase recovery (erase recovery partition)

fastboot flash recovery recovery.img (flash new recovery partition)

fastboot oem unlock (unlock bootloader to run root commands)

fastboot oem lock (relock bootloader as factory to not admit changes)

fastboot help (show help with all commands)

fastboot reboot (reboot phone)

fastboot reboot-bootloader (reboot phone in bootloader mode)

fastboot update superuser.zip (install app to root phone)

fastboot -w (erase userdata and cache, is this reset to factory?)

or install new rom with:

fastboot flash bootloader bootloader.img

fastboot reboot-bootloader (wait phone to reboot before continue next command)

fastboot flash radio radio.img

fastboot reboot-bootloader (wait phone to reboot before continue next command)

fastboot -w update rom.zip
