What's the purpose of the Engineering SPL?
When you get radio S-OFF, you already have access to most of the bootloader's commands, so what exactly is the purpose of having the engineering SPL when you already have radio S-OFF?
It lets you use fastboot commands. I can't really say much other than that because I don't have it, either. One thing people like about it is you can flash individual partitions like
fastboot flash partition partition.img
but functionality wise I also fail to see how a PC10IMG.zip cannot achieve the same result. I'm sure a more knowledgeable person can enlighten us
I don't have the Engineering HBOOT either but as I understand it the main benefits of having it are it gives you some more options for fixing things if you get a semi-brick as you can flash a new recovery and run other commands from fastboot.
Of course the risk is (and why I don't have it) that if something goes wrong with flashing the HBOOT you have a brick.

Well, when I rooted my phone via the method on the xda wiki, I unintentionally installed the Engineering SPL. I just copied and pasted all the commands since I have Ubuntu 11.04 on my computer.

Well, a PC10IMG.zip will only work if your main software is less than 1.19.531.4 (For G2. I don't know about Desire Z) otherwise, you're probably gonna be facing a semi-brick.

What is wrong with your current radio? You said if you don't like it can you flash back wich tells me nothing is wrong. Don't flash a radio unless your current one is giving you an issue plain and simple

if you have s-off and have sdk/adb you can fastboot flash Safest way to flash radios,
if not there are PCIMG radio that you can flash through bootloader, and yes if you dont like the outcome of it you flash your original radio back

The PCIMGs as well radio.imgs
radio.imgs are for fastboot flash
PCIMG are for bootloader flash
need engineering hboot to use radio .img files
use the PC10IMG.zip method to flash your radio via stock hboot, easier in my opinion. Just make sure u rooted with gfree and superCID is set to 11111111.
Read this if you need to check what your superCID is set to
In all honesty tho, while im all for people who want to learn how to tweak their own devices, if you dont know what adb/sdk is, or you dont know what HBOOT or gfree is, you shouldnt be messing with your radio. I foresee a brick

Lol if dont know what sdk/adb should be or have root, but gotta start somewhere,
and CID doesn't have to be at 11111 if jus unlucky few need it, as well its better recommended to have but not really a necessary thing, i dont have CID set, was able to flash PCIMG

Before flashing a radio I highly suggest you call you carrier first and see if its something they can't fix if the issue is data. Make sure you know what speeds your area is capable of as well. But as mentioned before this if you don't know what these key terms are don't mess with it untill you read up and are confident.
I know what I'm doing but I usually check with my provider first to make sure nothings up with the network. You know part of your cell phone bill includes "free support" right..use it
dont send me pm's crying about how i hurt your feelings in a thread

Whichever method you use, wipe all partitions (except FAT32 on SD) after changing.

I have only used fastboot and never had any problems with it. at start it might seem the harder way but when you do it a couple of times it probably is the fastest and easiest way to do it.
also just a reminder, if you wanna change back from cm7r2, flash the downgrader first, then flash the other hboot you wanna go for. (i have learned this a lot later than i should have therefore i feel the need to share it)

Personnally I'm a fan of Fastboot Commander. It can be found at the bottom of the Desire Index in the development thread.
You got a few hboots for alpharev then you can make your own layout as you need, so rom will fit perfectly. As I'm trying different Rom flashing hboot as it is required for that specific Rom.
Now I find fastboot much quicker way as fastboot commander with mouse

if i remember correctly, you need to use the downgrader first to switch from 387mb system hboot to cm7r2 for example

You are remember not correctly. One only needs to use downgrader when one wants to flash RUU or OTA, because the new hboot versions have only overwrite protection against RUU or OTA (Source: http://alpharev.nl).
I've changed from CM7r2 to stock and back again a few times now (when trying out the ICS ROMs that are floating around on here), and have never flashed the downgrader. As MatDrOiD points out, that's only needed if you're going back onto a RUU.

Help, I think I messed up my phone (HTC Desire Z). I tried 2 root my phone. But after I s-off my phone I tried to reboot it and... It woudn't work :c. Can anyone help me? I searched for it but I Didn't find anything what can bring my phone back up. Please Help me someone.
well after the downgrade process you would be @ froyo, I'm sure a diffrent os then you were using, this would have changed you radio/spl and rom at the same time so there would be a functional os. after obtaining s-off and a eng hboot then you in a sence wiped your phone of an os, therefore it will not boot.
one of the things in the guide you followed (assuming you followed a proper guide and did things correctly) was to install a custom recovery. boot into recovery and flash rom of choice... now your phone works

Thank you so mush for your replay. But I don't know what you really mean. I did follow a guide @the unlocker. And I did every step correctly. But can you maybe give me a guide what I need to do? I'm just a android noob :c. What to I need 2 do exactly?
not sure what the unlockr uses for root, if you don't have an eng hboot then you may not have fastboot access. just boot into bootloader and check
first some lines should say either eng soff or ship soff, if it is ship soff I suggest following a different guide to root as you will have many headaches without an engienering spl
also the search function works quite well in both xda and google, just look for terms like adb for dummies, or fastboot commands. if you are having issues just report back with your findings

If I Try to use ABD It say's Device is offline. Or Cant connect 2 device. Ant It says 'ENG S-OFF' and when I try to Recovery there happends nothing, There is just that a triangle with a. ;C i'm so desperate.
then your rooting method did not get you a custom recovery, you will be best of going to irc freenode #g2root, here you will get real time help. being you have an eng spl there is a good chance things can be fixed. just make sure you jump the gun and try to flash a pc10img.zip from hboot, if you flash the wrong one you will be stuck for good, so be double careful how you proceed from here
just google search irc freenode, and sign into #g2root and create a temp name, if no one is there to help right away just stick around a bit and I'm sure some one will show... be patient

Calling your g2/dz crap doesn't make it so, it just sounds like you don't know what you're doing and then complaing that it must be the phones fault... kinda flawed logic.
But if you want some help rooting it why don't you post a copy of your cmd output/imput and we can see where you went wrong. Also maybe link the guide you're following as there may bed a better one that is easier for you to understand

The phone is already rooted and S-off
During the rooting process and gaining true radio soff you will have a custom recovery.
Did you follow the YouTube video to root then?
The only method you won't to use to root is with gfree
Either follow the xda wiki
Cyanogens wiki
Or straw metals PDF guide
For the most part anything else you do will cause you problems
Sent from my HTC Vision using Tapatalk 2
Yea, I followed the youtube video.
How can I roll it back to s-on?
i just quickly looked at the youtube video and it seems it was having you run gfree for the exploit which is good but doing it through terminal emulator not through adb. shouldnt be an issue doing this but im too lazy to go through the video and see if it was telling you all the right things, either way you need to check and see if gfree worked.
check THIS POST out, follow the steps at the bottom and see if gfree worked. if you have true radio s-off than flash one of the pc10img.zips through hboot or fastboot - fastboot is the preferred method as if there is an error it will tell it to you and you can choose not to reboot until it is fixed.
if you need further help feel free to ask
Just checked it.
But got one question
"~make nandroid in recovery"
How can I make a backup without recovery? :x
As long as it says secure flag zero you are safe to use the pc10img.zip
The nandroid is just so you can restore easy, instead just flash a new rom
But you may just want to flash the recovery through fastboot if you're not interested in changing radios etc, so long as you have an engineering SPL you can do this, if not flashing the pc10img.zip will give you one.

Slightly out of my depth here, but go to the thread demkantor posted a few posts up and read carefully, it will be very informative.
Also you appear to be using stock Android recovery, I'm not certain this is a problem but just to make sure I would find out how to use fastboot to flash clockworkmod recovery. Just Google "flash clockworkmod recovery fast boot" or something along those lines... If you already have android SDK set up, etc. Which I assume you must have being as you're rooted, it shouldn't be too difficult.
Sorry this is about as much as I can help, I'm sure demkantor will be able to help you through anything more than this.

THIS THREAD will teach you how to use fastboot to do
various things such as flash a new recovery. problem is you dont have a bootloader with fastboot

done using the gfree method than you can simply flash one of the PC10IMG.zips from
post 30 in the thread linked above (done via bootloader) if not it could be an issue to use do this.
you can only flash update.zips through the recovery you have now and they more than likely would need to be signed by htc. if you dont have a working os right now then
you may need to flash an ruu (one that matches your phone) let me know where you stand on all this
