[Q] Are you able to flash a rooted stock Ruu Rom with hboot 1.50

Hey guys i was wondering if you can flash a earlier stock rooted Ruu while on hboot 1.50 with the htc unlock method. If you were to flash one of the stock rooted Ruu, would that downgrade the hboot version to the earlier versions. Or did Htc lock down the hboot 1.50 version from being downgraded. Any advice would be helpful.

[Q] I can't unroot HTC Legend and back to stock rom

Hi all , please help because I can't unroot my HTC Legend and back to stock rom.
Specs are:
Legend PVT Ship S-On
HBOOT - 1.02.0000
MICROP - 0816
RADIO - 7.13.35.05
DEC 23 2011
I've tried to install the RUU from HTC DEV but I can't..give me an error whe toll is Updating Signature - Error 140 Bootloader Version Error
Then I've relocked the bootloader on HTC Dev...and nothing
What am I doing wrong? I have to switch to S-OFF to unroot it? or to downgrade the HBOOT to 1.01 as I have it before to root it?
Thanks
Which guide did you use to root?
I believe the best way now is to use the boot unlocker method, guides are found in this forum section.
Therefore you will not need to downgrade or any of those tedious methods we once had to do.
I've tried to use the tool from htc dev to instal the _WiFi security fix_RUU_Legend_Froyo_S_HTC_WWE_3.15.405.6_Radio_47.51.35.17_7.13.35.05_release_222317_signed...but I can't...gives me error when it try to Update Signature to my phone.
I just want to reinstall the stock rom because the battery before to root took me about 2 days....and now when it's rooted and with custom rom it takes me less then a day and has some bugs ( now i have this rom: [ROM][RC4b][10.09.2011] Gingerbread 2.3.3 with HTC Sense 2.1+ )
Use hack4legend from this thread. Then downgrade to an older RUU and install all updates via OTA. You'll get back to HBOOT 1.01 and an untouched bootloader.

[Q]HBOOT Downgrade via OTA?

I have a GPE One m7 converted from am ATT m7 and I am currently s-on and I have the 1.57 hboot. Did anyone know/think it will be possible to flash a stock ROM and recovery then flash an OTA containing a lower HBOOT version than my current one (specifically an OTA with the 1.44 HBOOT) and successfully downgrade the HBOOT to 1.44?
Any responses are greatly appreciated.
Thanks.
I didn't think you could downgrade to an h-boot version that was not used with the Android version you're on. I think 1.55 can only downgrade to 1.55.

absolutely not.
You need s-off to downgrade hboot nd must be done by flashing a RUU or a firmware in RUU mode.
