With this method, what if something goes wrong? Before, you used clockwork to backup before flashing a new rom... if i understand this method correctly, there isn't that option. Would you have to reload clockwork with fastboot to restore a backup? (and it it possible for this method to break something that isn't backed up by clockwork?)
Edit: Actually, it seems clockwork is installed. Maybe the install guide should add a backup stage?
I call this install method the Total Phone Transplant -- because it can change everything that we know to be changeable on the phone. It changes the stuff that loads Android at boot time (which is how the program-storage-space is reallocated), as well as the contents of the usual /system and /data partitions.
And it also overwrites the recovery partition (where Clockwork lives).
So, if the install goes wrong, it probably goes VERY wrong.
To get out of deep do-do (not booting AND Clockwork not working), you need to do another TPT. Either with a new (and md5 checksum-checked) copy of the new image, or to go back to the old ways you'd do a TPT with (for now) the Hungarian update in the /sdcard/image folder.
Loading in that image gets you a Hungarian phone, just like it came out of the box. (Importantly with the partitions set back to standard.)
From there you'd need to re-install Clockwork (and perhaps again network-unlock your phone) before restoring your Nandroid backup.
BUT, if the install goes as it should, then you will have a whole new phone with the one install - including Seb's right-way-up Clockwork. A word of caution though - its probably best NOT to simply restore your old Nandroid into the new partitions (it might not fit -- depends on which rom you were running before). If you go through the Hungarian update and re-install Clockwork, then you can be sure that your old nandroid will fit.
"Predictions are always difficult - especially about the future."
I'm going to predict that there will soon be tools that will make these processes simpler.
And that more roms will take advantage of the TPT technique.
