You need to install a ics update.app and then use the code to unlock bootloader from fastboot.
Thanks, but I am not familiar with ics upgrade.app....would I be better to do as you suggest here...
If I am on Cyda Stock+, using the GB Bootloader, as I had to, would just flashing two zips in recovery??
As you said:
NOTE: If you are using any stock based ICS rom (like Stock Plus, Lightning, Infusion, B952-slim, etc), you can install the zip to downgrade to GB (look HERE) and then install the zip to use ICS roms in GB. You don't need to make wipes or reinstall the rom, just flash those two zips in recovery and reboot. I think this method is better than relocking the bootloader.
Would that save a lot of messing around??
Does this method, your one above, also flash a kernel [Ouch] for use with the GB baseband? can it give o/c etc??
Thanks, and sorry for any stupid questions.
EDIT...seems some have had problems, those on MVNO operators.
I am on Tesco mobile in Ireland, MVNO using O2 Network here, and I really don't want to have a problem with Network Data, as speeds are not the best anyway.
Which solution do you think is best?
Your ICS on GB baseband, with locked GB bootloader, as above....
or the new solution which involves unlocking the ICS Stock Bootloader, which involves going back to Stock ICS first, unlocking ICS bootloader, and then reinstalling Stock+ or whatever ROM??
Can a Nandroid made before the unlocking be restored safely [would it restore the original Bootloader, or is this ever backed up??]
Sorry again, but it is confusing and don't wanna brick wifes phone, life is hard enough already....
