I'm not content with the performance of KitKat ROMs on the desire and wanted to try an older Gingerbread ROM. I wanted to try MildWild 5 or Oxygen 2.3.2 but I'm having problems.
I was on HBoot Alpharev Jelly (250/5/182) and was running TWRP I tried to flash the HBoot oxygen r2 alpharev, which worked fine, but then I couldn't boot into TWRP any more I just get stuck at the TWRP boot logo.

I guessed it was maybe due to system partition being too small for twrp (?) and flashed cm7r2 hboot, but that didn't help, still stuck at TWRP boot screen. After that I tried to flash 4ext v1.0.0.5 RC9 recovery, but this one boots without showing me any buttons (really strange). I can drag down the "Welcome to 4EXT Recovery Touch by madmaxx82 (...etc)"-screen so this recovery seems to work a little bit?! Useless without any buttons tho.

I'm really confused and don't want to continue as I'm apparently not as certain about what I'm doing as I thought I was.
Do I need CWM Recovery for gingerbread ROMs? Are TWRP and 4EXT not working because system partition is too small? (as I said above, I'm atm on Bravo CM7 r2 (145/5/287) from

What do I need to do to get older ROMs working?

Recovery is installed to a separate partition, not the /system partition so that's not the problem.

TWRP or 4EXT should work fine for installation of any ROM. I personally used 4EXT for older GB ROMs no issue.

All I can suggest is to redownload the 4EXT recovery.img, check the md5sum and flash using fastboot

As a last resort, backup everything (apps/contacts/SMS etc), and flash the 2.3.3 RUU to go completely stock (+stock recovery)

Then S-OFF and flash 4EXT again.

I'm very puzzled at the moment.
I thought running the 2.3.3 RUU won't get you back to S-On as alpharev hboots are protected? I also don't quite see the reason for going S-On again.

I tried flashing TWRP 2710, TWRP 2630 and 4EXT v1.0.0.5 RC9 using either fastboot or PB99IMG-method. I get no errors while flashing, but the recoveries don't work properly. TWRP always gets stuck at its boot screen and 4ext boots, but then doesn't show me any buttons. I checked the MD5 of the images before flashing every time.

My bootloader atm shows me:
AlphaRev CM7 r2

I was on TWRP 2710 when I changed my hboot from alpharev jelly to alpharev oxygen r2 (or now alpharev cm7 r2). This recovery has a bug which deletes the tmp directory all the time (you can't flash from this recovery unless you run "mkdir tmp" in a terminal). Could this be the reason why the recoveries now are not working any more?

I think I'll try to flash alpharev jelly and restore a nandroid (to see if a recovery would work then) before running a RUU.

Flashed alpharev jelly hboot and the recovery is working again (atm twrp 2630)

So how do I do this properly without running into the same problem again?

Simply wipe everything except for the SD card of course and then flash your new hboot.

It works now.
What I did: Flash 4EXT recovery on alpharev jelly, flash manwild from recovery, wipe everything except sdcard, flash alpharev cm7r2, flash Manwild
No idea what went wrong in the first place, but everything works now and the ROM is great!
