DISCLAIMER. Do it at your own risk.. I am not responsible for bricks....bla bla bla, usual stuff.
If in doubt-STAY AWAY!
Q/A First.
Do I HAVE to flash this FW? - YES, if you want to flash ICS 4.0.3 based rom. If not, it just won't boot. Latest firmware works with previous (2.3.4,2.3.5,4.0.1) roms.
Do I NEED SuperCID? - YES, it will help in case you need to revert and if your CID is not on the update.zip list
Will I lose S-OFF? - NO
Can I use this FW with earlier builds? - YES
Will I lose fastboot commands like flash splash1? - Yes
Is it safe? Never 100% but no fails so far. Flash at your own risk
Can I revert to previous hboot, like 1.17? Yes, make sure you are superCID.
Any disadvantages? None so far
Any advantages? More optimised fw/drivers for ICS. Users report faster ROM operation.
Why does it say ***LOCKED*** in bootloader? Because hboot is locked (don't panic)
Can I go back to **REVOLUTIONARY**? Yes, flash 1.17 HBOOT at the bottom of OP.
HOW TO
0. Make sure you are S-OFF and superCID. Check HERE
1. Download zip from HERE Credits to rmk40, this is FW I used).
2. Do nandroid backup.
3. Copy/paste PG58xxxxx to the root of your microSD
4. Make sure MD5 match!!! MD5 checker I use HERE
4. Make sure MD5 match again!!!
4. And once again, make sure MD5 match.
5. Reboot into bootloader (if you don't know how to do it, don't do any of that at all)
6. microSD will be scanned and will ask you if you want to update, press +vol for YES
7. Follow onscreen instructions.
8. Now just pull sd card out if you don't have microSD reader or delete PG58xxxx if you do. PG58 will prevent you from going into recovery if phone sees it.
9. Reboot into bootloader-go to recovery
10. Put your SD card back in
11. Reboot or flash new rom
12. You are done. Just delete that PG58 file so it doesn't stop you getting into recovery again.
REVERT TO 1.17 HBOOT
Paste on root of SD card, make sure MD5 matches. Repeat update from bootloader (steps 1-12 from above) and you should be done.
If anyone has anything to add, feel free.
Remember, if you flash RUU, then process is slightly different and will most likely involve unlocking via HTCDEV (haven't really looked into it)
If in doubt-STAY AWAY!
