ROM upgrade help

[gekkko]

I wanted to install one of the ROMs from www.yorch.net. But before doing so I have some questions:

1. If I choose to build ROM as an installer.exe, is installing it to my device as simple as running the .exe file? (of course with the device connected thru Activesync)
2. Is my present ROM (see specs below) supported?
3. If Murphy comes to visit and I screw up, will my phone be completely unusable or can I just reinstall old ROM, do hard reset and everything will be back to how it was?

My specs:
OS: Pocket PC ver 3.0.12039
ROM:3.20.06 ENG( 07/30/03) (O2 Asia I think since I bought it here in the Philippines)
Radio: 4.21.00.

Thanks

1 as far as i know yes havent don it to my own device yet though

2 a rom dont have to support a rom since it'll overwrite it

3 of cause merphy can also show his ugly face
but if all fails a sd flash reader writer can save many a tears
also if your phone is working ok then i would not mess with the
radio stack and beware because some roms include the radio stack
and if you try to update your radio stack to a US (900/1900) and you network is 900/1800 you could be in for a world of pain

OK I'm really dying to give it a go but I'm just a overly cautious bloke. So I'm gonna outline what I interpreted (after reading lots of posts I think I'm getting it but not sure) to be the way do the upgrade. Please correct me if i'm wrong:

Equipment I have:
1. My notebook (Windows XP, Activesynch 3.7)
2. O2 XDAI
3. Cradle and USB connection.

Steps that I think I should take:
1. Place XDA on cradle and make sure it's connected with PC.
2. Backup?? (not so sure what to back up since contacts, calendar, notes are synched with outlook, docs are also synched, I have copies of cab and program files since I download them to PC before installing them to XDA.) If i'm missing something please slam a frying pan (this is a kitchen right?) on my head.
3. Go to www.yorch.net, check mark on all appropriate options, then (since I have to Unix box and dont know Unix at all) just go for the easy option of cooking the .exe install file.
4. Assuming, the .exe is downloaded to my PC. This time I just run it. I expect this to be just like installing PPC apps. If not, throw a tomato on my face :)
5. Assuming everything worked and Murphy's in the Arctic freezing his A**e off, then all I do now is hard reset.
6. I have a new ROM and I'm singing happy-happy-joy-joy.

To the wonderful people at xda-developers, am I in the right direction or am I as lost as Bill and Ted? If I'm lost, is there a step-by-step guide for non-unix programmers? (Sorry, there was a sticky but I thought it was for people with Unix boxes)

Once again, thanks for all your help and your patience.

well i can think of one thing to backup and thats your current rom
so if you dont like the new rom you are getting you have the option to go back
of cause if the rom you have now is downloadble from a place you know like your isp then maybe it dont matter

[gekkko]

Thanks for the reply. That's a good point. Question: When you back up old ROM, is it just the ROM that gets backed up or is it the whole content of the device, like how you do in PCs?

Also, since no one, besides you, has made any comments regarding the steps that I outlined, is it safe to say that they are the correct steps?

Thanks

When you backup your ROM, no stuff that you customised will be in the backup - the backed up ROM will be the same as when you received it from your retail shop, or if you upgraded, it will be the upgraded ROM without any of your stuff. Do a backup and store it on your hard disk.

DON'T use the .exe cooked ROM, use a .nb1 or .nbf, and use XDA Tools from this site to do the upgrade. It's very easy that way, and less dangerous. Don't upgrade your radio stack unless you know exactly what you're doing, or your phone supplier has made an update available just for you.

If you use a T-Mobile ROM above version 4.00.05 it blocks the XDA-Tools from updating the ROM. At that point you need to use XDARIT (from this site) to low-level write the ROM image you have onto your SD card using an SD card reader which shows the card as another drive on your computer. Once you do that you need to boot into the boot-loader (press the reset button while holding the power button) and follow the prompts to restore from an SD card. If you're unlucky and are running bootloader 5.17 (or above I think) you need to write the bootloader diagnostics patch (wallaby patch from this site) onto your SD card first before doing the boot into the bootloader thing. You can then remove the SD card, write the O/S ROM onto it with XDRIT, and put it back into your phone while it's still sitting on in diagnostics mode. Then you can restore from the SD.

It sounds complicated, but it's easy, as long as you have an SD card reader, and as long as you don't mess with trying to update the bootloader or do an unknown radio update. There's lots of info in these forums if you get stuck.

I made a thread that summarised all the steps using the new tools and ROM's at this address : http://xda-developers.com/phpBB/viewtopic.php?t=3860. It's for Asian/European users, but if you are in the US the instructions are the same, except instead of using European 900/1800 radio you use 900/1900.

Thanks. It's becoming clearer and clearer. Have more clarifying questions:

1. How do you know whether or not you're including the radio stack with the ROM upgrade at yorch.net. I did not see any options there.
2. At www. yorch.net, nothing happens when I press the "Build ROM Now" command button. Is the download supposed to happen in the background or is there something wrong with my PC or the site?
3. I dont think I'm using the T-mobile ROM but how do I know if I'm runing bootloader 5.17? Is bootloader 5.17 only for T-Mobile users or all?

Once again, thanks for the help and bearing with a newbie.

it should start to write some text about the progress of making the rom
and when it's finished then it should init a std download dialog

[gekkko]

The meter down at the status bar does move, same as when you're loading a webpage, then it says Done. That's about it. Didnt see any other messages or dialogue boxes.

Can anyone confirm if it's up today or has it been down?

Thanks

PS. Tried to email using the email utility at the website but getting errors there as well.

OK, firstly to answer your question about Yorch's site... well it worked for me in getting all the ROM's I wanted, then when I went back again the download didn't work. I guess it's just on and off, so unless Yorch finishes getting married or someone else makes another kitchen it's a matter of pot luck. You can get away without using the kitchen if you can find another download source for ROM's, whether it be FTP or whatever. Just remember if you get an exe you can usually pull it apart with winzip to get the .nb1 or .nbf out of it.

Now, for Q1 :

An operating system ROM is generally just under 32MB, but when zipped from Yorch it's usually about 14 or 15MB - the operating system ROM will NEVER be smaller than that. I'm not sure about the exact radio stack size but I know it's a lot less than that. Also, doing some homework about the operating system ROM helps. eg. reading about the 4.01.00 ROM tells you that it's not a radio stack upgrade, it's an operating system upgrade - and the filename and the size of the file you receive reflects that.

Q2:

answered above...

Q3:

I think the bootloader is just pot-luck depending on when you phone was released. To check your bootloader it will reset your device completely, but I read somewhere that if you turn the radio (phone) off it doesn't hard reset. If you're worried, do a full backup first. But basically when you're ready to look, reset your phone while holding the power button and it will tell you the bootloader version. Don't be too turned off by that, I have read that SD card readers can be picked up very cheap if you look around, and that's all you need to get you out of trouble regardless of the bootloader version.

There's no real risk (but I won't guarantee anything), just make sure your phone is fully charged before mucking about with SD upgrades. Also make sure the radio (phone) is switched off before upgrading... using the bootloader/sd card method you shouldn't need to be concerned. I'm not sure what effect having your phone on and receiving a call while using XDA-Tools can have, but someone did mention it somewhere.

I'm a newbie too, but there's really not much you need to know, just a few caveats.

Yorch's Kitchen has been working OK for me the last couple of days. It takes maybe about 5 mins to "cook" before telling me that the ROM is ready. The 4.00.05 ROM gave me a lot of ActiveSync problems, so I went to the 4.00.16 ROM tonight and it looks like it's behaving better.

My SD reader is a Microtech Zio. It appears as a disk drive in windows, but the newer XDArit can't initialize a connection to write to the SD card. I used the "dangerous" older version of XDArit instead (available on Yorch's site), and it's worked OK for me (so far?).

One thing I wish I had realized before I started playing - going into the bootloader will reset your phone most (some?) (all?) of the time.

While I was flashing the ROM tonight I could see the GSM light flashing - I had the same "hope no one calls" feeling tht others must have had. Note that this was while I was flashing from an SD card in the bootloader - so apparently the process doesn't deactivate the phone while it's ongoing.

Ebswift, if ur a newbie then ur the god of the newbies. Thanks for all the help and for making me see the light. Much appreciated...

A quick Q:

Is the process for installing an .nbf file the same as that for installing an .nb1 file?

I have cooked a few ROMS to an .nb1 format and installed those OK, but now I have one in .nbf that I'd like to install.

So what I'd plan to do is put the nbf onto an SD card using XDArit, and then stick the card in the PPCPE and reboot to the loader. Is that it?

You can do it that way (onto the SD card), or if you're not already using a T-Mobile ROM you can use XDA Tools which is easier. Basically the capabilities are spelled out for you with the available file types in the drop downs when you select a source.
