Don't think you can downgrade if you used the Windows method. At least not easily.

This assumes you are on gen2 having used the Windows method - the flasher modified by radmir

If you have upgraded Gen1->Gen2 using wbaw's TPT method, ignore all the information below and get yourself to wbaw's pinned topic on this subject

Also I am assuming also that you currently have the correct IMEI on your phone. If you don't, then I think you will probably need to restore this using one of the approaches described elsewhere on here. For all I know, it may be that you can put your (correct) Channel1.nvm in the flasher before you begin and it may rewrite the correct IMEI, but I don't know since mine was fine when I did a dry run of this earlier

If you no longer have the correct IMEI, there are ways of generating a replacement, and I advise you to follow the guides to doing so located elsewhere on the forum (eg this one Update-save-ur-bricked-v880-and-also-the-imei)

So, this is compiled from information given here in posts by CaptainSpectacular principally, though dibbles and others contributed also

CaptainSpectacular has put together a .rar with all the important files, simplifying this process significantly

Mauritzius added the final piece of the jigsaw, enabling one to restore the correct IMEI. Basically, the upshot of what Mauritzius' realisation is that noone on this forum has been using the flasher correctly to download so far, since when it stops at 98% during downgrades, people have been assuming that's the job done, while it plainly isn't - there was still work to do, but the flasher was giving you a chance to flash a Gen1 ROM before completing the job. In fact there were two flashers in the original download, one of which I seem to recall was for downgrading Gen2->Gen1 out of the box and may well have had all the correct files already for all I remember, but that's irrellavent now. I've run through this method a coupld of times and a few brave souls have followed my directions and provided very helpful feedback. It seems to be fine, but as always, I accept no responsibility if anything whatsoever bad happens in your life subsequent to your reading this...

Paraphrasing CaptainSpectacular's directions:

1 Put a ROM on your SD that's compatible with both Gen1 and Gen2 so you can boot no matter what Gen you end up in (should end up Gen 1 of course, but this will guard against pilot error!) Swedish Spring release 5 is a good bet

2 Make sure your phone can access "FTM" recovery mode, ie you need to get rid of the recovery mode you probably have at the moment, most likely clockworkmod recovery. You do this by checking restore_stock_recovery.zip is on your sd card then flashing it in clockwork. Likely you will have this file on your sd card already from the original flash from gen1 to gen2 (if not, hecatae uploaded it here)

3 You need to download the flasher next: GEN2 to GEN1 Windows.rar.

4 Unpack GEN2 to GEN1 Windows.rar. Find the flasher application, download_nochecksGen2.exe. Double click this to launch it - you will see a window with "OSF flasher patched by Radmir" at the top. You will recognise this from when you first upgraded Gen1-Gen2. We'll come back to this in a minute - now over to the phone...

5 Switch your phone off, then reboot holding the Volume button pressed down, as you ordinarily would to access Clockwork. Your android should disappear to show a white square with FTM written in it. If you find that clockwork starts up, this means you haven't flashed the stock recovery yet. Flashing restore_stock_recovery.zip from within clockwork right now would be a good idea (as mentioned in 2 above). Then reboot again with the volume - held to access FTM

6 Plug the phone into the PC and look at your PC to see the flasher program ("OSF flasher patched by Radmir")

The start button previously wasn't clickable but now will be

Go on... press it!

Watch as the progress meter increases all the way to 98%, at which point it will stop

7 DO NOT unplug the phone until I say so!

This is mauritzius's bit - very clever bit of lateral thinking...

The phone will have booted into clockwork (v2. something - green text) at 98% to allow you an opportunity to restore a Gen1 ROM before continuing with the last 2% of the downgrade, where the flasher goes back and restores your IMEI to what it was before you began this downgrade and completes reinstating your TPT priveleges. In order to let the flasher do that, you need to flash a new ROM for the phone to boot into then get the phone back into FTM mode again, just as you did a little earlier

i. So, still within clockwork, flash the Gen1 ROM you want the phone to boot into next (Swedish Spring anyone? It's useful here cos if you've done this wrong and are still on Gen2, SS will still boot ok).

ii. Before you leave Clockwork, flash restore_stock_recovery.zip again

iii. Only then, when you've flashed both the new ROM and the stock recovery, reboot from within clockwork, holding the Volume - .

The flasher will spring back into life and will do the final 2%. Leave it until it tells you it's finished ("Download complete" message flashes up)

8 NOW you can unplug the phone and reboot properly. When your ROM boots up download Ask Mr Pigfish and run it to make sure you have gen1 (bloody better have, after all this)

9 Check your IMEI is as it should be

10 Do whatever you like next - your TPT options should be restored, so you might wanna go and download and flash a TPT Gen2 upgrade with CM7 as per curl66's directions

I think all this is right - I tried it out earlier and it worked fine, but I don't want to waste another half hour of my bank holiday checking it again!

Let me know if there are any obvious errors and I'll make corrections

EDIT - thanks to CaptainSpectacular for uploading the rar with the correctly modified flasher - it didn't occur to me to do this!

Thanks also to shootomanUK and ThrashMan for feedback

If anyone's interested I did a similar guide a couple of weeks ago on how to upgrade Gen1-Gen2 using the windows method. I don't advise you do this though unless you have a very good reason as you will lose TPT

Yes you can - instructions to follow, compiled from other posts

Assuming you mean after flashing using the windows method

yes i upgraded through windows to gen2, im just looking at a guide now but im having trouble getting the phone into FTM mode it just keeps booting into Clockwork Recovery ??

[Guest CaptainSpectacular]

1 You need to download two archive files to being with: gen_conversion.zip and gen2_to_gen1_128mb.7z

2 There's a folder called files contained within gen_conversion.zip that we want to replace with another one called files inside gen2_to_gen1_128mb.7z. This is how you do it...

Extract the first file (gen_conversion.zip). In this folder you find 2 folders, to_gen2_org_partitions and to_gen2_128mb_system, also partition_layouts.txt and restore_stock_recovery.zip. Of these you can use either of the partitions archives, but lets use to_gen2_org_partitions for the sake of argument

Extract to_gen2_org_partitions

In the folder produced you will find a folder (called files) and 8 other files. Delete the folder (files)

Extract the second file you downloaded (gen2_to_gen1_128mb.7z ). Inside is a folder called sysdy. Inside this is another folder called files.

You must now copy this folder over from sysdy to to_gen2_org_partitions. Again, there will be one folder and 8 other items in this folder

Nice one dude. Just little suggestion, it'll be nice if we can just upload a .rar with all files inside, so it'll be less difficult. Here for example. Just check if all the files are inside if you want to post it. :o

Plus you can put some images and it's can be sticked. :mellow:

Anyway good work, I hope this will help lot of people.

ouch !

4 You need to make sure your phone can access "FTM" recovery mode, ie you need to get rid of the recovery mode you probably have at the moment, most likely clockworkmod revovery. You do this by making sure restore_stock_recovery.zip is on your sd card (this was in GEN2 to GEN1 Windows.rar),

restore_stock_recovery.zip is not in the zipped package ??

[Guest ThrashMan]

Great guide SoupThief :mellow:

I think step 7 needs ammending though? It says when the phone reboots into clockwork to reinstall default recovery.....you should install ROM first then default recovery otherwise I couldn't get to clockwork after s/w reaches 100%, I just kept ending up in FTM again.

Yep he's right. I think at the 98%, when the phone has rebooted, you must flash a ROM (SS RLS5 is perfect for that), then stock_recovery again (in this order !). Then you can reboot with "Volume -" and the flasher finish the task. I didn't test this method but it's seems to be the right way.

If you just flash the stock recovery you'll have ... nothing... :D

Also here's a link to Stock_recovery. (thanks to hecatae)

Maybe you need to refresh the guide SoupThief. Good luck. :o

Hiya

I tweaked it earlier on, with a link to a bundle of files including the stock recovery, but will change it to hecatae's upload as it's a smaller download

EDIT - done

This assumes you are on gen2 having used the Windows method - the flasher modified by radmir

Thanks for the feedback - really pleased to hear it's working for you

I'm going to repost this in its own thread and perhaps one of our friendly mods can pin it

Not sure if there's anyone left on Gen2 through windows who will want to make use of it though...
