[Wing, P4350 Herald Upgrading] iPhone iWing:
This is for ne one that is looking for detail in making their Wing/Herald hard spl'd

Please do not get mad at me if it does not work.. But there are a ton of success stories with flashing Wing/Herald to Hard SPL..

#1:

Ok first check your ipl and spl.. You can do this by entering bootloader. bootloader (push the pin hole right under volume slide and hold camera button) you will then enter bootloader.. It looks like 3 color bars and say's ipl 4.xxxxx whatever and spl 4.xxxxx same.. Whatever the 4.xxx is thats what ipl and spl you are.. In order to become hard spl you must at least 4. and higher.. So if you see a 4 then your good..

#2:

Ok now that we have checked, soft reset your phone again and let it load.. This will get you out of bootloader and back to normal mode.. I was very careful on flashing.. So i always reverted back to oem rom.. So get the oem Wing rom or Herald rom.. If you can't find it let me know because i have it.. So just flash oem and let it be stock rom..

#3:

Ok now is getting ready to start from the very beginning.. Now if you have the 3 cabs (canonyang.cab, aserpolicy.cab, disablesecurity.cab) just install them in order as writen . After they were successfully installed soft rest your phone again..

#4:

Ok now we start the flash.. Its a scary few moments lol.. But very worth it.. Make sure you are synced and connected to your comp.. I also was extra careful by resetting my comp and making sure all windows were closed and made it so windows weren't open.. But i was extra careful Check the circle and make sure its green or if you have vista it'll be the pda icon lite up.. now open your hard spl folder (the rar. or folder that you dl'd for from the main page) and click on ROMUpdateUtility. Now just wait for it to finish the flash.

- If all goes well then it will come up something like Yang something something.. You will see a dif splash due to you dl'ing a new rom that makes your phone hard spl'd. Let it finish and your good.. Soft reset and enter bootloader and see if spl is 4.70 yang.. If so congrats your hard spl'd!!!!!! fo sho...

* Now to flash other roms all you have to do is get your oem rom and right click on it.. Extract it and you will see its contents.. Among its contents delete the spl.nbh file. Not the ruu.nbh.. Now you click romupdateutility.. I would make the extracted oem a special folder because this is now your new flashcenter.. Ne time you would like to flash a new rom all you have to do is simply replace the rom .nbh of your liking in this folder that you made and run romupdate.. All done.. Easy flashing.. lol.. Welcome to hard spl world!!! Now you can flash at ease.. Ne Herald/ Wing rom you have is now flashable except roms designed for micro sd cards (trasflash cards) Just use the .nbh files..

Please if you are are not ok with my instructions and wish special help(detailed help) with this put it on this thread. Others will learn from others concerns.. Even if the ? has been asked a million times still ask.. Please ask ?'s before flashing if something does not go with instructions..

Once again i'm not responsible for ne thing that happens to your wing/herald.. I am simply trying to help in-detail and be at assistance in ne way possible..

This is the dl from the orginal Hard SPL page. It contains everything thing you need.. (cab. files, .nbh for flahsing and romutility for flashing)
