Fatal downgrade...

[illanz]

Hi there,

My currently installed Rom was RUU-Prophet-G4-AKU2.2-2.20-2.47.21-Jester-r1.exe. (thank you jester for you good job)
Nevertheless, this ROM is in English and I wanted to downgrade to a French One before the selling of my device.

I have tried to install the downgrade kit detailed in this topic : http://forum.xda-developers.com/showthread.php?t=267344

The first step went OK but while trying to make the secnd step, my qtek is blocked at the boot splash screen showing the Jesterz picture and red information about the SPL and so on on the upper left corner... without starting... The USB connexion is not detected so I can't do anything... While trying to install any ROM, the USB connection is not detected ang I get an error message...
Did I kill my phone ?

Please help ! Tell me that it's not dead....

Don't worry, its nowhere close to being dead. If you have superCid, then use the SD card image to restore in bootloader mode. However, if the Cid is locked, then you would need a utility that can unlock Cid without Activesync mode (coz in your case, you would not be able to get an Activesync connection). imei-check.co.uk has a utility ($38 i guess) that unlocks Cid in bootloader.--- else show it to a professional. (in my country, I would have to shell out around $20 to get such a problem fixed at a mobile repair shop)

Just take out the battery for about 10 minutes and re-insert. If it does not re-start, do a soft resert with the stylus and hopefully you should be fine :)

Hy,please help!
after downgrade, it doesnt work anymore.... i mean... i cant start the mobile!

after the downgrade i disable the USB data cable and now the mobile is dead... it doesnt starts from the ON/OFF Button and even if i connect the USB cable it makes nothing! No Led on... nothing! absolutly DEAD!!!

[illanz]

I have tried to put off the battery all night long with no result.. but I have achieved to reach the bootloader mode by pressing the camera button while soft reseting and keeping the camera button pushed...

OMG, I have been so scared ! ! !

[illanz]

Try this in order to reach the bootloader:

Hold down the camera button and reset the device. (Boot Loader Mode is: Press Camara + Soft Reset, then release soft reset and KEEP PRESSING camara button till appear the Boot Loader.)

[stolymp]

it doesnt work

I seem to have a simular problem. this is my post in another topic. It seems to fit better here.

This is what I tired so far:....

I used the RUU_Prophet_2151327_21513121_021921_DOP_ASIA_WWE_S hip-NoVendorID and it often hangs and was slow with Push Email over GPRS.
I tried to find a way to downgrade but hadn't had time sofar. When I logged on XDA Developers Site I saw there was a new Image.
So I thought Great I dont need to find how to downgrade.
I don't know what G4 and G3 is so as everybody let's try the higest best one.
I uploaded the RUU-Prophet-G4-AKU3.3-Jester-b1
Wrong...
Now as previously stated I get to the multicolor screen with IPL 2.09 and the SPL 2.20..0001 on the screen and that's it.
I can get to the bootloader and load the same image again and get the same result.
I can load another image on and it loads to 80 Percent and says error [326] Invalid Command This NBF cannot be used with your PDA Phone. Please check your NBF file.
If I try an older Version it tells me upgrad only
And when I try to upload the G3 version it tells me error[300] invalid upgrade tool. This upgrade utility canot be used for your PDA Phone. Please get newer Upgrade utility.
Trying to use the nf.nbf or the G3 with the ROMUpdateUtility_NoID of the G4 doesn't work either.
If I would like to do the downgrade tool I need a Active Sync connection which I don't have.
I have no more thoughts. Please Help.

If you would have just read the forums better you would have known if your device is a G3 or a G4. (read this! (http://wiki.xda-developers.com/index.php?pagename=prophet_g3g4_how)).
Now it appears you have tried both for an update. Which may possibly have bricked your phone.

But... first things first. Can you get into the bootloader? (read wiki HERE (http://wiki.xda-developers.com/index.php?pagename=Prophet_Hardreset_bootloader) on how to do that).
If you can still get into the bootloader then there is still a possibility for updating.
Try upgrading with the latest Qtek rom (note: this is an official rom, this one works for both G3 and G4! And since it's the latest you should be able to upgrade to this one).
Instructions quoted from another post of me:


You could try the 2.20 qtek rom which seems to be working well for quite some people (found here (http://forum.xda-developers.com/showthread.php?t=283245)).

Although you have to make sure you read that thread good and use the ROMUpdateUtility_NoID.exe (found here (ftp://xda:xda@ftp.xda-developers.com/Prophet/Tools/ROMUpdateUtility-NoVendorID.zip) ) to upgrade.

Update instructions:

1: With the qtek 2.20 rom you need to extract the zip and the exe file in the zip with WinRAR.

2: Then there is one folder called 'OutputFile' and a folder called 'RUU_TOOLS'.
Inside the RUU_TOOLS there is prophet and in that one WWE, when you go through them and in the WWE folder you see a bunch of files (readme.doc, enterbootloader.exe etc etc).
You need to copy ROMUpdateUtility_NoID.exe to the WWE folder with all the files. And you also need to copy the 'nk.nbf' file to the WWE folder (from the 'OutputFile' folder).

3: And then you need to put your phone in bootloader mode and run ROMUpdateUtility_NoID.exe to upgrade, which should work nicely then.


This should give you a good enough idea of what to do. This should work (new rom combined with no NoID updater).
However, if it's impossible to get yourself into the bootloader your options of upgrading your device are getting smaller.
Downgrading of a complete rom is only possible on a CID unlocked G3 (when it's CID unlocked you would know! because you would have done that yourself) and not on a G4 device.
Flasing a G3 device with a G4 rom or G4 device with a G3 rom might possibly turn your phone into a brick. This can easily be avoided by reading the forums properly and know what you are doing.
If anything (even if it's a small thing) is not completely clear to you about upgrading/downgrading your device I'd recommend not doing so.

edit: oh yeah... if you have a G4 device (which you should know by now) you cannot downgrade from this rom (well, only via a payed online service). And when you have a G3 device you could try and CID unlock it (read wiki + forums) before you want to downgrade, or don't downgrade at all.
But whatever you do, don't try to downgrade it without doing any of those things because you'll get into trouble. (to put it down bluntly)

If you have reached the bootloader screen, just run my installer (or any official ROM) to get your phone working again.

[gmarcel]

I need help, to restore my Prophet, i upgrade wrong rom, i need will try the SD Backup, where can i see this process ?
Sorry my Inglish is too bad.

[Jesterz]

I've merged a couple of threads under this one, as they are all about the same problem (mostly)
Opening a new thread for the same problem isnt very useful ;)

Hi RaptorRVL
Thank you very much for your patience in resuming all this for me.
I do try to read the forum but it isn't like a manual where you find the procedure stepby step. Like the G3 and G4 version I have newer come across until now. Sorry.

I tried the image you metioned and I have the result that at 80% it tells me error [326] Invalid Command This NBF cannot be used with your PDA Phone. Please check your NBF file

Any more thoughts?
As you seem to be an expert Can you let me know more about goldcard solution.
Cheers
Mick

From a readme I once found inside an update:


* ERROR [320~328] : INVALID COMMAND

These errors seldom occur. However, if one of these errors occur, it could not be recovered and the device had to be sent back to the customer service center. In this case, you have to flash a new ROM code.


Doesn't sound too good really. Maybe someone else here on the forums know what to do with this error :/

You did use the ROMUpdateUtility_NoID.exe and not the normal updater right? Can remember someone getting a similar error when using the wrong updater, but I'm not sure about that though...

edit: try doing a search on the prophet forums for "INVALID COMMAND" maybe there is a helpful post in there somewhere...
