Default method 2: use htcdev instead of taco root

reported working!

this method should work for any future builds,as long as we continue to have unlock support,even if taco root and other exploits fail. it may at some point even warrant its own thread.



download miniadb_inc2 from above

1)unlock with hctdev,install recovery,flash root files
[guide] unlock with htcdev

2)downgrade with adb
*from this point forward,all commands will be in bold you can copy,then paste them into the cmd window,one at a time. blue are just additional info/comments,and should not be copy/pasted

md5sums RUU_Vivo_W_Gingerbread_S_VERIZON_WWE_2.18.605.3_Ra dio_1.09.01.0622_NV_VZW1.92_release_199487_si.zip should return cea499f51b40055ffd118960e1e73255. if youh ave trouble here,search the pasted line for spaces that shouldnt be there.

md5sums 1.09.01.0312_vivow_Radio_PG32IMG.zip should return ea6b98be48210d7797e62362f49ff751

md5sums misc_version should return 050f55d34ddbcc860efa5982491437de

adb devices should return your phones serial number. indicating drivers are working,and youre connected.

adb push misc_version /data/local/tmp/misc_version

adb shell should change your prompt to a #if not,have your phone awake and watch the screen to grant superuser permissions when you enter su

chmod 777 /data/local/tmp/misc_version *have your phone awake and be watching it,incase superuser needs you to grant permission

/data/local/tmp/misc_version -s 2.18.605.3

exit exit again if your promt changes to a $

adb reboot bootloader

fastboot devices again,this should output your serial number,indicating youre connected and drivers are working

fastboot getvar mainver it should output 2.18.605.3 if it does,then procede. if not,something above was not entered correctly,and the downgrade will not flash. reboot your phone using the command fastboot reboot and start again at step 2.

if you did get 2.18.605.3 then continue:


fastboot oem lock *may casue a security warning if youre on a cusom rom,or extrememly modded stock rom. if it does,dont panic,this is normal. in a worse case if the ruu wont flash,you can simply re-unlock with your original unlock token. relocking the bootloader may cause your phone to reboot. if it does,simply let it reboot,renable usb debug,disable fastboot,and adb reboot bootloaderback to fastboot. then procede

fastboot erase cache

fastboot oem rebootRUU

fastboot flash zip RUU_Vivo_W_Gingerbread_S_VERIZON_WWE_2.18.605.3_Ra dio_1.09.01.0622_NV_VZW1.92_release_199487_si.zip (as above, if youh ave trouble here,search the pasted line for spaces that shouldnt be there)

this part will take some time,so please be patient,its not hung. it will check the file,send it,then start writing. do not under any circumstance interupt the phone while the writing is flashing in the comd window,indicating partitions are being written to.

once you get OKAY and finished. total time: xxx.xxxs then:


fastboot reboot-bootloader

this will take your phone out of RUU mode,and back to fastboot. note that you now have hboot .97

fastboot reboot will boot you fully into the revolutionary-able 2.18.605.3 firmware.

download and run Revolutionary

you can have revolutionary install a recovery,or install one manually after s-off is achieved. included in miniadb_inc2 download is the 0312 radio,wich you will need to flash if you start experincing bootloops.

if you need to flash the 0312 radio:
putt the phone in fastboot mode(select fastboot from hboot menu),open a cmd window,change to miniadb_inc2 directory then enter:

fastboot erase cache

fastboot oem rebootRUU

fastboot flash zip 1.09.01.0312_vivow_Radio_PG32IMG.zip (when you checked it above with the md5sums command,it matched right?)

fastboot reboot-bootloader (make sure your baseband changed)

fastboot reboot



i personally reccomend amon_ra recovery. you can find it here: [Recovery] Amon Ra Style Recovery for Incredible 2 vivow - xda-developers
