iPad Firmware upgrade questions

iPad 1 w/ iOS3.2, baseband 6.15

Tiny Umbrella saved SHSH 4.2.1 (none other)

Found this step by step guide (have never done this before):

Questions:

1) do I need to preserve baseband - if so how
2) if upgrade fails will the unit still have iOS3.2

i know im not answering the question, but if you dont mind me asking. What is the point of preserving the baseband on an Ipad?? idk i thought basebands were only good for unlocks??

Future JB might be nice - don't know if that involves baseband.

Do not want to end up with iOS 5.1

Found the 4.2.1 firmware is over 500mg. Any idea how long I need to allow for this to write to the iPad?

well i believe using the latest version of redsn0w you can. go to the "more" section. then go to "even more" click "restore" click "ipsw" and point it to the right firmware

The current baseband is 6.15

Phone Wiki says that 4.2.1 uses baseband 7.10

So not sure if installing 4.2.1 would change the baseband and if that is would be a problem if I wanted to JB at a later date.

iPads are always "unlocked" so updating BB doens't matter, it's not tied to a certain carrier.

Updating the firmware does update the BB, you can however make a NO_BB custom IPSW to upgrade with redsn0w, but it isn't necessary.

Why don't you want to upgrade to 5.1? There is a tethered jailbreak out for 5.1 and the untethered one is only weeks away.

Always save your SHSH's for current and future firmwares, using TinyUmbrella for that is easy.

Thanks for the BB information.

I saw the inst. for redsn0w no_bb but having never done any of this before wanted to go the simplest route with least likelyhood of error (i.e. brick).

Posts by users here say the original iPad runs slow with 5 and the 4 is the best.

THis is not true as far as my personal experience goes
