[Upgrading, Modifying and Unlocking] pdamouse:
Wow that was an adventure. I just did the upgrade to 23034. I tried both the Active Sync method, as well as the micro-SD method, and neither worked. I always got stuck on the first screen (WM6.5 welcome screen). I just got it to work now, I can now access the 6.5 menu, sometimes - but my phone no longer charges, the screen washes out when I plug in the USB, and it does not Active Sync anymore. Also the ASUS menu no longer comes up on boot, just the WM6.5 menu after a few seconds.

I used the pim split method to get my own EXTROM and GSM settings in the end, but it seems I still ened up with the Indian settings instead of the North American ones (the carriers are not local to me).

Still trying to fix it...not sure what to do. I can't seem to go back to the original ROM to reset it...and I'm not sure why the upgrade didn't work in the first place...

Update:

I think the pimsplit is what killed it, before that I would at least get the ASUS screen - but after trying to pimsplit my P527 is now bricked. I recommend against anyone else trying that. I did follow the steps from post #1 about it. I was using the same pim file from the 6.1 official ROM I originally flashed my P527 with. I'm still trying to fix it...

Update 2:

It says there is no GSMFFS - and when I try to do a microSD update it says it is "Format and keep G" - so it may not be formatting all, which seems to be what is required. The GSM part of the phone does not appear to be working at all, it does not have a list of carriers, and the ASUS logo still does not appear on boot. Also when I connect USB nothing happes, no LED works, Active Sync does not work and I get an "Can not open UFN driver!" error while in WinMo 6. The screen whites out after a few seconds and doesn't return till you insert an microSD, eject it or randomly when you hit some of the other buttons. The ON/OFF button no longer works, not much does.

I don't know if this has any bearing on things, but I tried to do the update without the SIM, now it appears there is no effect. The phone option is gone in WinMo 6. I am able to flash 6.1, 6.5 and 6 - but only through Micro-SD. If I try to do it via the computer installer over USB I get the error:

"GSMFSS at 0x13000000

GSM Doesn't exist

Spin Forever

Use (fomrat All) instead."

Update 3:

Google found me this answer:

"

Hi.I head the same problem and it's solution:

http://rapidshare.com/files/227192658/full.rar (WM 6.5)

1.Unpack and copy this on sd card up to 2GB

2.Put card to phone

3.Lock phone with hold switch,press OK (next to volume control) and camera together and now reset.

I hope this fix your phone.

With that I now have the ASUS blue screen back on boot, as well as a stange looking SCHIST ROM 21189.5.0.0 on my phone. Hoping now to put her back to Win Mo 6.1 and then go to sleep for the night...

Update 4: It worked, I now have a workable phone again :) Confirmed 100% working, with GSM reading my North American operators correctly, phone works, boots fine, all as it was before. - I think that is enough ROM updating for me for today. I will wait for someone else with North American ROM to confirm 6.5 before I try again.

I suspect you guys probably had this happen before, I didn't use the pim installer versions from the first page because of the (IND Version) = Indian version I assumed. Maybe that might have worked at least to let me restore it - no idea. All I know is that my own pimsplit from both the official North American WinMo 6 and 6.1 P527.pim files was somehow corrupt and probably what caused all the problems. Maybe if we have a North American pim version it will work for me, but I can't seem to create it - I just almost bricked my phone trying... - If I don't use the microSD upgrade method it hangs on boot, and if I use it with my own pimsplit files it bricks the phone ... any help on that would be great - well I'm off to sleep now though happy that I am no longer the proud owner of a brick :)
