rooting and flashing htc magic 32b, is that the right way?

hi at all,
since i'm very new to this whole android thing, i just want to make sure if the following guide is ok for my phone, i don't wanna brick it^^
Phone:
HTC Magic (with Google) Vodafone branded
SAPPHIRE UNKNOWN 32B SHIP S-ON G
HBOOT-1.33.0007 (SAPP10000)
CPLD-10
RADIO-2.22.19.26I
Jul 31 2009,15:49:25
FW 1.6 (untouched)
Build-Number DRC92
i wanted to use the tutorial in the androidpit wiki (sry, can't post a link since i'm new^^) and it's german, so i'll translate that for you:
what i need:
astro file manager from the market
flashrec-newestversion.apk
cm-recovery-newestversion.img
DRC83_base_defanged.zip
update-cm-newestversion-signed.zip
optionally: update.Engineering-SPL-HBOOT-newestversion-signed.zip
vf-sappimg-crc24-1.33.0007.nbh
1. rename vf-sappimg-crc24-1.33.0007.nbh to sappimg.nbh and copy it to the root of the sd-card
2. power off and then on with volume down hold down
3. push trackball 2 times to install the nbh, reboot after downgrade
4. copy everything else to the sd-card
5. install flashrec with astro
6. start recovery flasher, download recovery image, then backup recovery image then flash recovery image then reboot into recovery
7. while rebooting hold home+power
8. select Nandroid v2.2 Backup
(9. optional) apply any zip from sd and choose the spl
10. wipe data/factory reset
11. apply any zip from sd --> DRC83_base_defanged.zip (NO REBOOT!)
12. apply any zip from sd --> update-cm-newestversion-signed.zip
13. reboot
will that work? and what do i need the engineering-spl for? would you recommend it? i read that flashing the spl is dangerous=) and where exactly is the exploit used to actually gain root access? i think the sappimg nbh is an altered recovery-image that looks like an updated recovery-image to the phone (and gets installed because of that) that is vulnerable (the 1.5 recovery? heard that one has the vulnerability), right? but why do i reflash the recovery-partition/image(?) then afterwards with flashrec?
and do i have to do something with the sd-card so i can use it? some kinda partitioning? i wanted to use the update-cm-4.2.15.1-signed.zip with the ram-hack.
thx for any help, suggestions or explanations and sorry for my bad english=)

PS: i'm writing this just to make sure the info i found is the current state and that it's compatible=)
EDIT: it worked=) cyanogenmod running=)

Should work as kitchen was one of dsixda updater script-generated.
ROM does not:
- busybox

- RADIO.img

just to confirm. i have ENG HBOOT 0.98.2000 (PG8810000)
will this rom be compatable with this or will it update my HBOOT to the new one when i flash the.zip? Aslong as it will keep my S-ON i don't mind

Sorry, I have not tested it because I have no DesireS

Added flashable Superuser and Busybox as ZIP-File on first port.

I think, you have confused me with michaelm_007. ^^
i don't think, it will upgrade your hboot. but i'm not sure. now i have a question. what is the difference between odexted and deodexted?

Apk files have respective odexes that devs use to supposedly save space. Deodexing means you convert it back to a .dex file and put it back inside the apk. This allows you to easily replace files (not having to worry about odexes), but the main point was to deodex services.jar so that you can change all text to different colors (such as the clock color to white) and to deodex services.jar, you need to deodex everything.

ahh okay. i understand. thank you!

i just tried to install but i get the following error message in recovery
"Amend scripting (update-script) is no longer supported.
Amend scripting was deprecated by google in android 1.5.
It was necessary to remove it when upgrading to the clockworkmod 3.0 gingerbread based recovery
please switch to Edify scripting (updater-script and update binary) to create working update.zip packages"

Mit der odexted Version kommt dieser Fehler:

For all users: I added a ZIP-File on Addons with a new Updater-Script (Edify), Busybox and Superuser.

so how would i install the rom now? do i do a full wipe then install the updater script addon 1st? then continue with the rom?

Download this File, open your ROM and replace all files with files from download.
updater-binary to META-INF --> com --> google --> android
updater-script to META-INF --> com --> google --> android
superuser.apk to system --> app
busybox to system --> xbin
sqlite to system --> xbin
su to system --> xbin
Final is: Edify script, superuser und busybox is include on ROM.

[Q] HTC Desire S is wiped and without clockworkmod [SOLVED]

Hi, i received HTC sense 3.0 and android 2.3.5 update. I tried to update it but it stuck on boot screen. Restarting didn't help. So I wiped all the data but later realised I no longer have clockworkmod installed.
I go to hboot and try to put recovery on sdcard through adb, but adb cant find my device.
Is there anything I can do? My phone is pretty messed up now, and I don't know what to do RUU also doesn't work, because my phone can't be found.
// #1 OK I managed to install clockworkmod through the Android Flasher. I've downloaded BeatMod BlissSense Hybrid v2.1.zip but I cant install it through the clockworkmod. It says:
"E:Error in /sdcard/BeatMod BlissSense Hybrid v2.1.zip
(Status 1)
Installation aborted."
// #2 sorry to bother.. I disabled the verification check in clockworkmod, installed su-2.3.6.3-efgh-signed.zip and then custom ROM.. everything now works fine. Of course with the help of tutorials on xda and great people over here.
This was the worst 4 hours in my live as I thought my phone is bricked.

good for u man

You don't appear alone with problem, so thanks for re-editing the thread post to provide updates, if you have the time and could try to add any URLs and links to the files that you used to resolve your issues, then that would be great!
I've already several threads where it appears the update has put others in the same position, so your update could prove to be a useful resource assisting the recovery of others!
Cheers.

[Guide][25th Feb 2012] Noob's Guide in Flashing ARHD 6.3.x

Noob's Guide in Flashing ARHD 6.3.x (UPDATE)
Hello there, I have noticed that many of the noobs like me are having trouble in flashing the newer ICS ROMs, Particularly mike1986's latest ARHD 6.3.0 XE ROM.
It's OKAY if I don't get recognition for my work. But my ultimate goal is to help Noobs like me
DO ask questions if there are any queries about the guide! I will be more than glad to help you.
Disclaimer
1. I Do NOT hold responsibilty in any bricked devices that are caused when following this guide.
2. I Do not own anything in the links provided. These are results of hardwork of mike1986, ziggy1001, xl VipeR lx, madmaxx82, Kohr-Ah & Hawke84.
3. Also you could visit joaquinf for a similar guide.
Basic Information
1. You will need, a HTC Sensation/XE/4G which is S-OFF and SuperCID-ed(optional - you will know later). xl VipeR lx made a guide on this Here
S-OFF in this case allows the Flashing of Files(Security Off) and SuperCID allows the flashing of ANY ROM to the device regardless of the carrier.
2. You will also need, a custom Recovery(4EXt, Clockwork Recovery etc), this actually Flashes the files, whereas S-OFF ALLOWs the flashing of files.
3. Please note to ALWAYS check the MD5 Checksum to prevent any bad downloads, which may result in bricking when flashed.
Preparation
1. Always, Always ALWAYS make a NANDROID backup of your current ROM. To do so, go to your Custom Recovery and Backup the Whole ROM.
What this does is that it simply backup everything ( setting, rom, software, etc.. ) and put it on your SD Card. If something was to happen(bad flash, bootloops etc), You can just go in recovery, and recover your phone with that. It then reinstall everything the way it was.
2. Even though you have already made a NANDROID backup of your current ROM, DO make a backup of your apps using Titanium Backup or System Tuner, So that later on when you are on a new ROM, you could still recover all your Applications & data that you installed on the previous ROM.
3. Download the Latest 3.30 firmware package by mike1986 from here
This is required due to the ROM being build on the 3.30 RUU* Base. Firmwares are basically what your phone needs to run the ROM.
4. Alternatively you can download the latest User friendly 3.30 firmware by Kohr-ah from here
To get your CID, To get your CID, you can simply use an app called CID Getter from the app store. After getting your CID number, just download the CORRECT file for your CID and download it!
5. Download the latest 4EXT Recovery Touch by madmaxx82 from here
6. Download the Suggested Radio, Superwipe Script and the Latest 6.3.x XE or 6.3.x ROM from here
7. Remember to check all of their MD5 Checksum with the MD5 Checksum provided by the Download Host. You could use FastSum to do so.
Now that all of the preparation is done, It's time for the actual flashing. Be warned!
Flashing the Firmware:
1. Copy the Latest firmware package (PG58IMG.zip) you have previously downloaded into the Root of your SD card("Main Page")
2. Copy both the Superwipe and the ROM files into the SD Card. Preferably the Root of your SD Card.
3. Power down your device and make sure it is fully off-ed and not in Hotboot mode. (Tip: Try pulling battery)
4. Boot your device into bootloader, if you still don't know how to do that by now, it's by holding down the Power button + Volume down together till a white screen with words(not HTC) appears.
5. Make Sure you have done SuperCID and the SuperCID number should be 11111111 (or not if you are using the "User Friendly Firmware Package")
6. The firmware package should be found seconds after you booted into Bootloader, press the power button to confirm update.
7. Let the bootloader do it's work and you are done! - Tip: Your device is expected to update halfway, then reboot back into bootloader and continue updating. In the meantime DO NOT TOUCH YOUR DEVICE.
It's is to note that Firmware 3.30 still has Fastboot commands enabled. This means that fastboot commands like getvar, push, fastboot reboot etc is enabled. This is usually related to ADB.
Now that You are done with the Firmware, now lets move on to the ROM. If you are coming from below version 6.3.x you MUST flash the Superwipe Script first before flashing the ROM, for instructions to flash Superwipe Script, see SuperWipe below.
Flashing the ROM:
1. Eject your SD card and boot into Bootloader.
2. Your Bootloader should now read
-Revolutionary-
PYRAMID PVT SHIP S-OFF RL
HBOOT-1.27.1100
RADIO-(your flashed radio)
*unchanged*
2. Select Recovery Mode and then quickly & swifly re-insert your SD Card.
3. Optionally, you could connect your Device to the PC using the "Toggle USB Storge" funtion on your recovery to delete the PG58IMG.zip. This would make your life easier.
4. Now, while you are in your recovery, select "install from sdcard" and navigate to your Superwipe zip and install it. Your device will now reboot automatically into Recovery again.
5. Now select "install from sdcard" again and navigate to your Android Revolution HD 6.2.x file and install it like you did to the superwipe.
6. Remember to select the Tick ONLY WHEN your device is HTC Sensation 4G at the first option (Tmos Fix).
7. Remember to select the Cross ONLY WHEN your device is HTC Sensation XE when it prompts you which Kernel you are installing. Removed as of ARHD 6.3.0
8. Do select the Tick for the Bravia Engine Support for more goodies!
9. After finishing the installation, select reboot at the Recovery Homepage and you are done!
10. Do note that first boots may last from 5mins to 20 mins.
Now, After flashing both the Firmware and the ROM, it's time to flash the suggested radio for ARHD 6.3.x
Flashing the Radio(optional):
1. Open your downloaded Radio file and connect your device via USB to the computer.
2. Select Charge only (works for me)
3. Drag the radio.img from the Zip file to the root of your adb folder(previously used in Writing SuperCID) and Open up the "Start Here.bat" file
4. Type in the Following Commands.
Code:
cd C:\adb
adb devices - to check whether is your device connected
adb reboot bootloader - your device should reboot into Fastboot Bootloader
fastboot flash radio radio.img - now let your "start here.exe" do all the work
5. When the "start here.exe" shows "finished. Total time: ---", type in this next,
Code:
fastboot reboot
Your phone should reboot & everything is done!
SUPERWIPE
1. At recovery, select "Install from SD Card"
2. Navigate to Superwipe script
3. Wait for it to finish flashing. - ARHD's Script should reboot your device back into Recovery.
4. Done.
How to make the best of your phone?
1. Now that you have completed flashing your ROM, you can proceed to Restoring your apps. Do take note to NOT restore system apps or system data.
2. Get Root Explorer and edit your Build.prop file (remember to Mount R/O - Open in text editor) and look for
Code:
# Increase overall touch responsiveness
windowsmgr.max_events_per_sec=60
debug.performance.tuning=1
video.accelerate.hw=1
Change the 60 you see into 150 and you should get something like this
Code:
# Increase overall touch responsiveness
windowsmgr.max_events_per_sec=150
debug.performance.tuning=1
video.accelerate.hw=1
Remember to Save the File! Root Explorer should also create a backup of the old Build.prop file.
3. To improve smoothness, you can also purchase System Tuner PRO and do the following settings.
Go into CPU settings, And set the governor to interactive, tap boot settings. Select "Force CPU1 Online" (to run both cores).
To offset some of the battery hit, I go to Screen Off Behavior, select On Demand governor with a max CPU speed of 540mhz. I leave the in call settings as is because I tend to do other things like look up information while in a call.
Set all the tweaks (such as sd card tweak, CPU settings, and Force ALL CPU Online) to run at boot completed. (as of 1.3, I now have them set as init.d script)
Reboot and I am done.

4. For ICS Fixes or Mods, Go to this thread by Hawke84 [Here]
Reverting to Gingerbread or below
Here's a brief explanation on what's going to happen.
1. You will have to flash firmware 1.17 - with referrance to "Flashing the Firmware" above.
2. You will then have to flash the previously downloaded Superwipe script
3. Only Then you could Restore your Nandroid backup if you have one, or flash your downloaded Gingerbread ROM.
4. And lastly flashing the Reccommeded Radio for that particular ROM or Backup.
If you have superCID, (11111111), use the 1.17 Hboot from here.
If you don't, use the 1.17 Hboot from here. Do note to download the right file with referrance to your MID and CID.
Hope you enjoy ARHD 6.3.x/ARHD 6.3.x XE.
Cheers!

For ARHD 6.2.x/ARHD 6.2.x XE you need or need not SuperCID.
You could flash the firmware package from this Thread
To get your CID, you can simply use an app called CID Getter from the app store.
After getting your CID number, just download the CORRECT file for your CID and flash it. You should be alright!

No, Thank YOU for your wonderful work

Had to move this to general, as it is not development nor a general guide, of which there is a number in development forum already.
Best is to tell arhd dev to include it in his thread.

Alrighty

I thought you don't have to flash new radio, if you flashed firmware ?! Isn't radio included in it ?

There is build 12 today....
http://forum.xda-developers.com/showpost.php?p=36487791&postcount=3281
Important things:
- it should be sim free (not locked to network, I think...)
- your Explorer should have unlocked bootloader (this you do only once in lifetime)
- your Explorer (pco) should be rooted first, if it is not. (this you need to do once, custom roms come rooted usually)
- you need to install custom recovery if you didn't already (CWM or TWRP) (this you need to do once,but you can change it..)
When you have all this, then proceed per instruction above.
Press "thanks" button if I helped

I would advice you to use build #11 rather than #12. Everything works on 11. 12 not tested yet.
To revert back you will have to do a nandroid backup first from recovery, if anything goes wrong while installing the rom simply go back to recovery and restore data!
Clear instructions given in posts on this site for all the steps needed.
