Worries about Upgrading

[staulkor]

I will soon have a Cingular 8525. I was thinking of upgrading it to the South African ROM. The one with the 1.09 bootloader.

I know the phone will have either a 1.04 or 1.06 bootloader so I can definitely unlock it, but I am looking for a full procedure thing. There is a lot with this, such as not being able to downgrade from 1.09 to 1.04 (which I found out you can actually do), and getting the SuperCID working, etc.

So could somebody be so kind and write up a procedure so I dont screw up a brand new phone. Thanks a bunch.

I second this request.

Actually I have read quite a lot about this on these wonderful forums by wonderful people but I am still not confident and therefore want to ask some specific questions:

1) My Jasjam original ROM is with bootloader 1.06. On the I-Mate site there is a ROM available with bootloader 1.04 and having the same CID as the one currently on my machine. If I install this ROM will my bootloader change to 1.04 from 1.06??

2) If after installing the ROM with bootloader 1.04 I attempt to install any other Hermes ROM say the Dopod ROM will it be possible simply by connecting my device with the computer through active sync and running the installation file on the PC?? Personally I think this will be possible as the bug in the bootloader 1.04 will allow me to do so.

3) My last question is that if after installing the i-mate ROM with bootloader 1.04 I install another ROM with bootloader 1.09 will I be permanently stuck with the bootloader 1.09 and afterwards not being able to install any other ROM.

I know some of my questions may sound foolish but I need the answers to gain some confidence that I have understood what I have read in these forums.

Kind Regards

@staulkor:
- Downgrade to cingular 1.30 rom to have bootloader 1.04 on your 8525
- Follow unlocking process as explained in the Readme file
- Double check that your radio version has changed from 1.13 to 1.16 after flashing the patched radio, once you're running the patched radio run Herm_Unlock_v2a.exe to SIM/CID unlock your phone.
- Upgrade to cingular 1.34 ROM again if you want the original ROM back on your device

@srmz:
1. yes
2. yes
3. yes, but read this (http://wiki.xda-developers.com/index.php?pagename=Hermes_Howto_Bootloader104)
