Guest Thunderbirds Posted August 20, 2010 Report Share Posted August 20, 2010 I got my desire with HBOOT 0.83 and i tried to root using unrevoked, after unrevoked my phone screen was blank and only can see the lights and the startup sound, Out of frustration i was finding a RUU which could be compatible with my phone and finally i flashed with RUU_Bravo_HTC_WWE_1.21.405.2_T2_Radio_32.41.00.32U_4.08.00.09_release_137222_sig ed.exe Works great and i got my screen back but now it says English UK during first time setup. once i connected to wifi it prompt me for OTA update to version 2.2, i just clicked yes and it went well but after reboot my HBOOT now is 0.92, which i believe im now on official 2.2 Now bad thing is later i found out that i cant gain root access with 2.2, I've tried many method to downgrade my bootloader back to 0.83 but its not working as the instruction said to place the PB99IMG.zip (ensured that its not zip.zip). When i boot by pressing vol down + power it says no ZIP found, I even tried making the gold card but no luck I've called the service center and told them i just got the phone few days ago and i crapped to them that the phone auto update the by itself, i also told them that after update the phone was keep hanging, So they asked me to drop by to their service center so they can downgrade back to Version 2.1. At this moment my phone is in Service center, i will be getting it back in another 2 hours. My question is, Assume if i back to 2.1 stock rom, how can i Backup everything just incase if i screwed it up again ? can i restore my stock rom ? i found few stuff like nandroid etc but there isnt any step by step guide I hope if anyone here could help me to guide to the correct way. I've become the premium member in Kitchen, I wanted to bake my image with wavesecure and have all the 2.2 features with root access Please advise Sorry for my bad english Link to comment Share on other sites More sharing options...
Guest EddyOS Posted August 20, 2010 Report Share Posted August 20, 2010 As you've found out you can't root HBOOT 0.92 (it's well documented) and you could've run the ZIP to roll back to HBOOT 0.80 and then just put an MCR baked ROM on it... If you use unrEVOked it will flash the clockworkmod recovery and you can do a nandroid backup before you flash a new ROM (you just select nandroid>backup from the clockworkmod menu) Link to comment Share on other sites More sharing options...

Guest EddyOS Posted August 20, 2010 Report Share Posted August 20, 2010 It's possible you've got an SLCD screen Desire so you'll need to follow the guides on how to get it back to stock. Read this, it's long but should get you working... http://forum.xda-developers.com/showthread.php?t=748498 Link to comment Share on other sites More sharing options...

Guest EddyOS Posted August 20, 2010 Report Share Posted August 20, 2010 (edited) I don't think you can...take a look around XDA as there's a lot of information on there... EDIT: found this thread, perhaps take a look...obviously do so at your own risk (and the 2nd part is the ROM flash, substiture the ROM names with whatever you wish to use. e.g. MCR r8 RC1) http://forum.xda-developers.com/showthread.php?t=750888 Edited August 20, 2010 by EddyOS Link to comment Share on other sites More sharing options...
