Downgrade to original Rom

[phariseu]

Hi all,

recently i upgrade my Tytn to last rom available here. I´m a bit disapoiting about this upgrade so i´m considering the possibility to roll-back to original rom.

Since last upgrade change my bootloader to 1.09 and my original was 1.04, to roll-back i just have to run rom package or i have to do something before the downgrade?

Thanks in advance

Hi,

I had this package:

ROM - 1.18.255.3 07/22/06
ExtROM - 1.18.255.106
Radio - 1.03.03.10
Bootloader - 1.04


and i instaled last one available here.

Rom - 1.35.255.2 11/14/06
Bootloader - 1.09
(....)


Let me say that i bought my Tytn "free" unlock. I have no problem about this issue.


Is there any problem instaling original package? Bootlader turns again to 1.04 or remains 1.09?


Thanks in advance

i think you still can downgrade it to the original rom version as the CID is the same, but the bootloader should remain 1.09. here's a quote from the wiki.

Bootloader 1.09 DOES NOT allow DOWNGRADING of itself by means of flashing earlier ROMs. Once installed it is IMPOSSIBLE to DOWNGRADE SPL 1.09 to 1.06 or 1.04 by regular means!

doesn't making the device SuperCID fix this problem?

and by problem, I don't mean getting 1.04 back, I mean there's really no point since you can flash any ROM you wish anyway, and I'm seriously asking cause I'm not sure

yes, if your device is supercid, you can flash the roms from different vendors. what is recommended for all is making the device supercid while you are still at the bootloader 1.04. if your device was made supercid while you had the original rom with the bootloader 1.04, you shouldn't have any problems with flashing whichever rom although the bottloader will remain 1.09 in your case.

You can flash any ROM that matches your CID. If you have SuperCID you can flash every ROM. The bootloader will remain 1.09 though.
