That was clear to me :) I just want to make clear that this may have unexpected side-effects, although it seems to already boot for some users.

Fully understandable.

> Due to the lack of time I need to avoid everything that could brick the well running v55 system. So I need to go one small step after the other. First step would be to update the bootloader. Will do that not before I'm sure to know again how to reflash the old one in case that the new one will cause problems with v55. What means that unfortunately it might take weeks or months until I can tell you some test results... 

No problem. Nobody expects that you try alpha-software on a mission critical system and have no method to back-up.

Regarding re-installation of older boot-loaders:
* they are all archived here: http://download.goldelico.com/letux-u-boot/GTA04/
* where I can't help is to find out which one you have currently installed
* and if there were any tweaks on your setup

Finally, migration may need to reset the u-boot environment variables, although we have tried
to make it as independent as possible. But going back o an older boot loader hasn't been
tested much.

So I'd suggest that you just make a fresh qtmoko+kernel SD card with makesd, but without u-boot:

DEV=/dev/sdb makesd qtmoko -r http://download.goldelico.com/letux-debian-rootfs/20180224-wheezy-7.11-armhf-qtmoko.tbz <http://download.goldelico.com/letux-debian-rootfs/20180224-wheezy-7.11-armhf-qtmoko.tbz>

This does not tamper with the boot-loader but adds the latest kernel for qtmoko2.

This should not take too much time to give it a try.

If it fails to boot, you could check the RS232 if there is something which can easily be fixed.

If it can't be easily fixed, the latest kernels are indeed no longer bootable on your u-boot (we have mainly added Device-Tree handling).

Is this a doable approach (not needing too much time and involving risks for the working v55)?

BR,
Nikolaus

I can remember that after changing the build sequence to use hardflow toolchain, Finxi theme was disfunctional for some time and required Radek to do some magic in order to get it running again in a later release. But never the theme was lost completely.

I would enjoy to support you again with some testing and I'm also willing to risc some regressions, as long as a) I can be sure that after replacing the old v55 SD card my system behaves like usual again and b) I can do the testing with Finxi theme...   ;-)

Since I haven't created a new SD card for my GTA04A4 anymore since several years, also haven't done any configuration for it in this time, thus forgot many details and also didn't want to spend too much time, but wanted to avoid everything that could brick my well working system, I thought I could be very clever by just going the following simple way:
