this is a guide to ultimately achieve a patched s-off hboot on your honeycomb htc flyer. the basic steps will be: 1)unlock with htcdev,install recovery and root 2)downgrade to gingerbread 3)run revolutionary 4)install honeycomb s-off hboot,firmware and rom a couple credits: -Team Revolutionary for the S-OFF and IEF for hboot -attn1 for the revolutionary version of clockwork recovery -Paul O'Brien for getting his hands on the early leaks,and patching clockwork to work with HC -globatron for the initial HC hboot,upgrade RUUs, and upgrade method found here: http://forum.xda-developers.com/showthread.php?t=1358758 first,download these files: 1)varioius_htc_exploits.zip 2)one of the following honeycomb upgrades,depending on the version of your flyer: a) if you have a wifi/3g flyer: http://hyuh.net/files/flyer/PG41IMG-3G-B09.zip md5: D6BA3D134B9D60C865187F42C66B996B b)non-us wifi only flyer: http://hyuh.net/files/flyer/PG41IMG-WIFI-B10.zip md5: f215eec88fe4b000cc9b3063c0724bdc c)us wifi(best buy) flyer: http://hyuh.net/files/flyer/RUU_US_WIFI_B10.zip md5: 8ffedc67d4c1032e601e81adf0cfebe3 3)a downgrade ruu. you will have to do a little bit of research on this. i will try and assemble a collection of what works with what,but for now,you need to find a gingerbread ruu that contains 1.10.0000 or 1.11.0003,and is compatible with your current CID. the easiest way,is to look at your build number: x.xx.xxx.x, where xxx will be unique to an unbranded ruu,or a specific carrier. for example: 3.61.1540.31 is a us wifi HC. to downgrade,you would use 2.27.1540.3,wich contains hboot 1.11.0003 an alternate method would be to simply create a goldcard,so you could downgrade to any ruu that you wanted. available ruus are found here and here i recomend to extract "rom.zip" from a .exe file in the following manner: -run the utility -check the "i understand" box and move on to screen 2 -hide the utility out of site temporarily -search your C drive for "rom.zip". you will find it in a temporary location -transfer rom.zip from the temporary location to somewhere you can find it easily on the PC(such as the desktop) -unhide and cancel the utility ____________________________________________________________________________________ 1)unlock with htcdev,install recovery and root Spoiler use this guide: http://androidforums.com/flyer-all-things-root/645207-guide-unlock-htcdev-install-recovery-root.html 2)downgrade to gingerbread Spoiler 1)extract various_htc_exploits,and then extract the zipped folder inside. move the file named "misc_version" into the mini-adb folder that you used to htcdev unlock 2)trasnfer rom.zip from your .exe above(or your downloaded zip file,if your downgrade ruu was allready a .zip file) into mini-adb as well 3)change the main version: -open a cmd window -change to your mini adb directory. enter: cd c:\foldername (example: cd c:\mini-adb if you didnt change the name) plug in your flyer,enable usb debugging,turn off fastboot in settings/power md5sums downgradefilename.zip compare the output to a known md5 sum,if available md5sums misc_version should return 050f55d34ddbcc860efa5982491437de adb devices should return your flyers 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 1.00.000.0 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 1.00.000.0 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 1.00.000.0 then continue: fastboot oem lock *may casue a security warning if youre on a cusom rom,or extrememly modded stock rom. if it does,dotn panic,this is normal. in a worse case if the ruu wont flash,yo can simply re-unlock with your original unlock token. if your phone reboots,thats ok. let it boot,re-enable usb bebug,and adb reboot bootloaderback to fastboot fastboot erase cache fastboot oem rebootRUU fastboot flash zip downgradefilename.zip 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 flyer while the writing is flashing in the cmd window,indicating partitions are being written to. if it fails with a hboot pre-update,dont panic,this is normal just enter again: fastboot flash zip downgradefilename.zip this time it will finish. once you get OKAY and finished. total time: xxx.xxxs then:[/COLOR] fastboot reboot-bootloader this will take your phone out of RUU mode,and back to fastboot. note that you now have hboot 1.10.0000 or 1.11.0003(depending on your downgrade) fastboot reboot will boot you fully into the revolutionary-able gingerbread firmware. 3)run revolutionary Spoiler download and run Revolutionary 4)install honeycomb s-off hboot,firmware and rom Spoiler -place the honeycomb upgrade into your mini-adb/fastboot folder. once youre ready to upgrade to s-off,rooted honeycomb: -open a cmd window -change to your mini adb directory. enter: cd c:\foldername (example: cd c:\mini-adb if you didnt change the name) -plug in your flyer,enable usb debugging,turn off fastboot in settings/power -check the md5sum md5sums upgradefilename.zip (it should match the md5 provided with the download above) -then: adb devices if you get a serial number,then adb reboot bootloader once in fastboot fastboot devices if you get your serial number back,flash the upgrade ruu: fastboot erase cache fastboot oem rebootRUU fastboot flash zip upgradefilename.zip as above,if it fails with a hboot pre-update,dont panic,this is normal just enter again: fastboot flash zip upgradefilename.zip this time it will finish fastboot reboot-bootloader note that you are now on honeycomb compatible revolutionary hboot 6.11.1111 fastboot reboot will reboot your flyer. congratulations,youre done. the upgrade ruu has installed 6.11.1111 hboot and matvhing firmware,clockwork recovery,and a rooted stock 3.55.405.1 build. you are free to enjoy as is,or go back and flash a custom rom.
