Q - People who were rooted, but then loaded 2.2 what PRI?

Ok, looked through the PRI threads and not seeing this. People who are rooted all seem to have used same engineering HBoot and have a PRI of 1.34_xxx. The 2.1 update 1 should have a PRI of 1.40 (I think, but different anyway).
So...people who were rooted but then loaded the 2.2 OTA...can you check what your PRI is? I am sure that the HBoot probably was not part of the 2.2 update, but still have a 'but what if' floating around in my head.
(If you are unsure...Menu>Settings>About Phone>Software Information> PRI (towards bottom))
Was rooted,downgraded to 2.1,loaded the leaked .3 and then used the leaked ruu to upgrade tp .6 and my PRI is 1.34_003
Neither the leaked nor the official ota upgraded the pri to 1.4.
Was rooted, did leaked .3 update, then OTA .6 update.
Have 1.40_003

Were you rooted with unrevoked?
From what I understand, anyone who was at some point NAND unlocked is stuck with the 1.34 pri

You were not fully rooted....because full root downgraded the PRI. You must have used unrevoked?

Was fully rooted with NAND Unlock, upgraded to leaked .3 version, then upgraded to Unofficial .6 Version, and still stuck at 1.34 PRI.
Are we SOL?

[Q]About NV 1.71 and PRI 1.77

Guys, I did a little search b4 post question here. Still had confusion about NV 1.71 and PRI 1.77.
1. According to some thread here, it says, after flashing nv1.71, the pri should "upgrade" to 1.71, so does that like nv is part of pri or what?
2. since i m still at 1.40_003 PRI, do I need to flash both to upgrade PRI? (Actually, i did HBoot way to flash 1.77, but met 4g network cannot be connected problem, so i downgraded, and try to fix the problem.)
3. After PRI flash, do i need to some update for PRL, thought the current version 60670, which was 60662 after flash?
4. should I flash in the order like this, NV --> PRI --> Radio --> Wimax?
thx in advance, really appreciate you guys here.
If you're rooted, why don't you just go here and flash them all at one time..use the COMBO by Calkulin: http://forum.xda-developers.com/showthread.php?t=715485.

Downgrading PRI and NV

If experiencing excessive battery drain with the 1.90 PRI, I have read to downgrade to 1.77. However, I've also read to downgrade the NV. Is this necesary to do the NV downgrade as well? Also, is there a certain order to flash these to downgrade? Will the PRI version affect the kernels I can use?

You don't need to downgrade the NV. It wont hurt either way. As far as I know, the only kernel that doesn't play well with the 1.77 pri is the stock htc #15. Any custom kernel will be fine.

Bump. Somebody asked me about downgrading the PRI to 1.77 and I didn't know if it was possible/easy. Can she just flash calk's 1.77 zip and call it a day or is it more involved than that?

Have you checked Caulk's thread for that answer...I don't think it matters if you flash one with out the other. If so I think the all in one would of been the only thing on the page.
I am trying this PRI 1.77 and hope my battery last longer ...

Yeah, I did after I posted that. Search was down for a bit last night and I couldn't find the thread.
I was having battery issues with pri 1.90 as well. Flashed just pri back to 1.77 and was still having battery issues. Then flashed 1.77 nv and now battery is strong once again on Myn rls5

After you've downloaded the PRI 1.77_003, place if on the root of your SD Card. You do not need to do downgrade the NV. Yes, the number of the PRI and NV are the same, but they are two different things and are not dependent on each other. Anyway, reboot your device into recovery. Wipe cache & dalvik cache and then flash the PRI just like you did when you flashed a Rom, a kernel or a mod of some sort. Afterwards, your phone will pause while the PRI is being downgraded and you may automatically reboot into recovery. If so, simply reboot and you're done. Yes, you will appear to hang during reboot because your device will be rebuilding the dalvik so be patient.

Help!!! Any way to downgrade radio from 2.15 to 2.05

First let me apologize if this has been answered before, but I could not find my specific question nor answer.
I am on baseband 2.15 and am trying to downgrade to 2.05. When I try to flash the radio in zip format, I get an error stating that my os is to new and that everything after 1.5 will not be able to flash this specific radio. This is not the same as downgrading from 2.15.x.x to a lower 2.15x.x. So please don't point me to this type of example.
Does anyone know, step by step, how to get this done?
Thank you in advance.
Edit: hboot 0.97
Radio 2.15.00.09.01
S-off
Rooted via unrevoked forever
Newer versions of the stock ROM may not work well or at all with older radios.
You may need to rollback to 2.2 to use the older 2.xx radios. 2.05.00.06.10 came out with the 2.2 froyo rollout. The newer gingersense ROMs probably can't be used with such an old radio.
Why do you need to roll back to 2.05 anyway?

Need to get my radio to a point where the nvm is writable.
Edit: update, got the radio to downgrade by using rom manager with clockwork recovery 2.5.0.7 and flashed radio update.zip
It was an amend error. An old version of Clockwork - as you did - or Amon Ra would be needed to flash it. Next time you flash radios (or anything that gives you that error) you'll either have to find an edify version or downgrade/switch recovery again.
