Any idea to flash ExtROM seperately safer and faster?

---

It is so cool to change ROMs of XDAII like changing OS on PC.
but experience of HimaUpgradeUt.exe is a really nightmare sometimes.
yesterday I tried 3 times and had to kill all processes on my PC and detach all USB devices except the cradle.
however, sometimes I can upgrade ROM at first time but still takes very long time.

I guess the reason is the cradle use USB 1.1 and HimaUpgradeUt must upload 3 ROMs one by one.

Is it possible to use other way to burn that ROM?
especially when we just need to amend ExtROM only?

why don't you do your changes directly in the extended rom?
and do a hard reset.
This gives you the same result as upgrading without changing NK and radio.

ofcourse you'll need extended rom unlocker.

How to change directly in the extended rom?? I am newbie here!! :shock:
Any links or guideline for me?? Thanks!!:wink:

this is the original thread for the extendedromunlocker on himalaya :
http://forum.xda-developers.com/view...t=8422&start=0

it creates a folder in Programs : Extrom tools
choose unhide , reset

now there is a folder on your device : Extended_ROM

when you want to do changes :
Programs : Extrom tools : unlock
now do your modifications there like you would in ER2003Edit:
* copy/delete cabs
* edit config.txt (easier on PC)

lock when finished modifying, for safety

tip : I have extromunlocker in my extrom, avoiding to reinstall, after every hard reset.

thanks for your reply!!
I already tried and it works!!
And... it is very good idea to include the Extromunlocker too..
