Guide to Cook Extended ROM for Uni?

[ireneus]

Hi,

looking for a guide to cook my own Ext Rom. I have looked at the Wiki, but found only tools for the Wiz. Can I use the same tools, or will I get into trouble. If there is a good Uni walk-thru available it would be highly appreciated. I already searched the forum, but did not find what I was looking for...
Thanks.

I unlocked my Extended ROM but I delete stuff it in. It seems its read only. Can anyone help me clean it up? I am sure that the WM speed will increase if the Ext ROM is clean. Also how can i lock it back after i clean it?

read only? after a softreset the files are still there? so u can use extended ROM "unhider" from indra.AKU3.2.BETA5R2....so u unhide and unlock it...then delete and the files are deleted forever ;-)


see attached ZIP ;-) install / execute both on PPC

Yes after a soft reset i still see the extended rom and all the files within it. The files are those Cingular and all those service providers etc and some skype and other stuff. The extended ROM is giving me 10MB of space on the device and I find it quite valuable. Rather than having it occupied by unneccessary stuff. Now this Ext-ROM unhider you speak of will let me write/read things from the Ext-ROM? Does it work with other AKU versions? Like helmi's aku 3.5? Thanks pixx

As always, care needs to be taken unlocking and unhiding the ExtRom. You can use the tools provided and they work well.

- First make sure to rename your 'storage card' to something else than 'storage card' since unhiding the ExtRom will make that the 'Storage Card' and your apps will not run from the SD anymore..
- It is not possible (as far as I know) to lock the ExtRom once you run the tools. But you can delete all the files inside to make it clean.
- The extended Rom space (10MB) cannnot be merge with the other storage, but you can install apps to it, or use it as storage space for attachments or whatever.

I am still lookng for a cookbook to make my own ExtRom...

Alright I formatted the Ext-ROM ^^ . Now that its empty i will relock it which will speed up the device right?

[ireneus]

No (re-)lock possible afterwards... just leave it as is.

No relock possible even after a hard reset? A hard reset usually restores the device to an unmodified state but it doesnt restore the data right?

[ireneus]

Never tried the hard reset uption so I can't tell if that will work, I flash my device about once a week with different (new) versions.
I may try next time I flash. Does anyone know?

Actually there is a way to relock the Ext ROM. I can't find the thread I read it from, but from what I remember you have to copy the registry settings BEFORE you unlock the Ext ROM. Then install Buzz's Ext ROM Unlocker. After a soft reset, the Ext ROM is now unlocked. Now customized it to your heart's content. Then cut and paste the original Registry settings to replace the new one. Another soft reset and your Ext ROM is now locked again. This is what I read from another thread. I had never tried this proceedure myself, so I can't guarantee it will work.

But, this is what I usually do whenever I customized my Ext ROMs:

1st: Install Buzz's Ext ROM Unlocker.
2nd: Soft Reset.
3rd: Customized the Ext ROM with CAB files.
4th: Perform a Hard reset to check if all the CAB files installed properly.
5th: Once I know every CAB files worked and installed properly, I now proceed with installing my other applications.

So basically, my rule whenever customizing my Ext ROM is: DO IT FIRST BEFORE INSTALLING THE REST OF YOUR APPS. This way you don't have to worry about LOCKING it afterwards.

The next time I will apply a new ROM (probably within the next couple of days) I will try this. One more question: Do I have to backup the entire registry, or are there some specific settings I should back up?

Merry Christmas!

As mentioned, I myself had not tried that approach. But to be sure, make a copy of the entire Registry and try it.

Another suggestion, if you have SPB Backup, this I already tried, so I know it works. Use SPB Backup to DO A BACKUP OF THE ENTIRE SYSTEM BEFORE INSTALLING THE EXT ROM UNLOCKER. After the backup, install Ext ROM unlocker and unlock the Ext ROM. You can now customize your Ext ROM any way you want. To RELOCK it, just run SPB Backup to the BACKUP you created before you installed Ext ROM Unlocker.

MERRY CHRISTMAS!!!!!!

If your purpose is just to delete the files in the "\Extended_ROM" (actual name when hidden) without unhiding it, there are a few ways, all works.

Method 1
- Google, download & install "Total Commander v2.exe" (freeware).
- In Total Commander's command line, just type \Extended_ROM , and you will see it.
- Before you do anything, suggest you copy everything to somewhere in case you need it back again.
- And now you can do anything to it. If it is really "READ" only, Total Commander also can "UNREAD" it. Think Total Commander can delete files with the "atrributes" (hidden, read, system, archive).

Method 2
- Download Helmi_c AKU3.5 V1.3, extract it, look for the ms_nbf in the Empty_Extended_rom, flash only this ms_nbf into you device, it should be empty.

Method 3 (need to unhide first)
- I am lasy to find out which Registry, so before unhide, I copied all the "Registry HKCR, HKCU & HKLM" (hidden).
- download Extrom_Unhider.cab & UNI_ext_rom_unlock.exe (should be in this forum or FTP)
- run Extrom_Unhider.cab first and following by running UNI_ext_rom_unlock.exe, you have unhide & unlock the "\ExtendedROM".
- Press POWER key to powerdown, then Soft Reset.
- You can also now copy "Registry HKCR, HKCU & HKLM" (unhidden/unlock) to different location of above "Registry HKCR, HKCU & HKLM" (hidden).
- So depend you want to hide/lock or unhide/unlock, just copy the respective set of registry. Easy.

@cktlcmd
Copy of Registry & copy back was my posting, anyway I also cannot find where it is, but it works, I tried it myself. :D
