[Q] How Install Endymion from RUU 2.10.401.8 and HBOOT 2.00.0002 S-On

Hi at all,
I need to know if what i saying is right.
I Have HTC Desire S with original Rom 2.10.401.8 and HBOOT 2.00.0002 S-On
My goal is to install the Endymion
I read many thread and i understood that the curret way to do this is:
1) Downgrade My ROM from 2.3.5 ( 2.10.401.8 with HBOOT 2.00.0002) to a ROM 2.3.3 with HBOOT 0.98.00000 (Ex: RUU_Saga_HTC_Europe_1.47.401.4_Radio_20.28I.30.085 AU_3805.06.02.03_M_release_199410_signed.exe)
To do this i need to follow the steps from 1 to 7 of this
http://forum.xda-developers.com/showpost.php?p=20535265&postcount=26
2) Now i need to change HBOOT, Change Recovery and Root the phone. To do this i need to use Revolutionary tool for Windows from http://revolutionary.io/ and follow the istruction.
3) Now i can download the custom Rom and install using this way:
http://forum.xda-developers.com/showthread.php?t=1257731
Is It right?
Thanks

100% right, just follow the instructions given by a particular ROM to flash though.
You can also look at HTCdev, but no point in using it (telling HTC you have voided your warranty) so I would use your method.
And 1.47.401.4 is Hboot 0.98.0002 (not that is matters though)

I have just done this this exact way and it worked great

Hi guys. I would like do the same thing with a Desire S, hboot 2.00.0002 S-ON.
After downgrading i'll have hboot 0.98.00000 S-ON.
Than, I should use revolutionary to get my phone S-OFFed and with a new recovery tool, is it right?! (Is there any guide, cause I'm a beginner...?)
Now, is my anroid 2.3.3 phone rooted?!?! So that I can install SU to remove app...
And now, if I would like to come back to android 2.3.5 with sense 3.0 rooted, can I flash a custom rom!? Or do I need something else, like installing clockworkmod recovery?
Thanks !!!

I would install 4ext recovery or the mentioned clockworkmod recovery.
After you have done so, you can flash any ROM (custom or not).
I prefer using a sense 3.5 ROM, but you can either choose sense 3.0 or AOSP.
But before flashing a new ROM you should always backup your system and data
Have fun!

I am stuck in the same situation as you, S-on, hboot 1.23, firmware 3.12, unlocked with htc dev and supercided. I'd tried some ICS roms without luck. Tried, too, a bunch of methods to revert back to an hboot that could be used with Revolutionary, but nothing worked.
So I'm using a gingerbread rom (Elegancia) while I wait for another method to try, or for Revolutionary to be updated to hboot 1.23.

Hboot 1.17

Hi all,
I am currently running on Hboot 1.17.1111. I had actually flash a coredroid rom, ICS onto my phone, without realizing that i need to flash my hboot to 1.27.
My phone was formerly flash on the gingerbread version. The rom was installed successfully but my phone now keeps restarting at the splash screen. I tried to look for solutions around to update the hboot with 1.23 then to 1.27. However, i am unable to install them. Is there any solution to this?
Thanks for the help

Pm your way put in sim card power volume down don't touch phone till u see ring will flash from and firm all in one shot then u can flash what u want
Sent from my Sensation using xda premium

why would you update to 1.23 then 1.27...from my understanding of it, all you need is 1.23 hboot to flash to ICS and 1.23 can also run any GB roms as well, whereas 1.27 can only run ICS Roms

i tried to update to 1.23 but it doesnt work as well.
oh well, i thot that i need to update to 1.27 for the rom flash

Hboot 1.23 is firmware 3.12 and that's outdated ics roms. All the new ones use 1.27

(advice needed) Hboot 2.00.0002, should I downgrade or not ?

I currently have a desires s (S-ON, not-rooted and bootloader unlocked), I am not sure if I should downgrade to hboot 0.98 as S-OFF for this is not available right now and as the title says I want you all to tell me what to do !
I could either keep this hboot and simply unlock the boot loader, root my phone and install a custom recovery to flash roms. But that way I won't be able to S-OFF my device and hence I wouldn't be able to install all custom roms such as virtuous saga which requires S-OFF .
And If I downgrade my device, I am not sure if the kernels,radio, and other things would be that efficient plus I doubt if I would be able to install all roms, like ICS Sense 4 roms
(kinda new to all this so I don't know if I am being a noob, but I seriously need your reply on this)
Sent from my HTC Desire S using xda premium

I can tell you what i did:
I unlocked my bootloader at htcdev right away when i got my desire s, then got superuser access to my phone. It was pretty fun, but I couldn't do EVERYTHING Plus, I lost parts of my warranty.
I really wanted s-off to be able to flash all roms available.
After a month or so, i did a downgrade of the hboot, with this instructions.
It worked flawlessly, although it's an hour of work or so if you're new to android. Terminal/ADB looks weird and complicating at first, but hey, you just need to copy the lines off the tutorial, it works perfect if you do as told
My advice: DON'T unlock at HTCdev (gives yo FULL warranty, even if you flash a custom rom), and just simply follow the downgrade instructions. Then you'll have full access, full warranty and no limitations at all, it's absolutely worth the downrade/s-off!
I'm running ICS now and couldn't be happier with my phone!

First of all thank you for your help on this, even I have had the same thought that its better to downgrade my phone and S-OFF it rather than keeping it S-ON.
Btw I came across anouther doubt which I guess its better to ask here instead of creating a new thread every time, : if I have to use an ruu to downgrade ny device, should my current radio (as seen in bootloader) match the ruu's radio ??
Sent from my HTC Desire S using xda premium

No

Have changed my Rom twice not touched the radio firmware at all.
If it ain't broke don't fix it, also read on xda somewhere radio firmware is a local thing it may work in your area but not mine

IMO, there is not much need for you to flash radio.. most of the time you won't need to do so..
and HBoot version can be changed if you are S-Off..
but i have to disagree with your statement that if you don't S-Off you are not able to flash all custom roms.. yes, some may fail to boot up, but mostly they will boot up without problem..
I am currently at the same Hboot as you, HTCDev unlocked and i have tried many roms without problem..
the only thing about having S-On for me is that i will always be dependant on my computer to flash ROM.. other than that, there's no problem generally.. Oh, maybe there is one thing, HTC may know that your phone has already been unlocked since you are using their unlocker.. but there are some ways to relock it and restore the "RELOCKED" in bootloader to "LOCKED"..
I am a newbie, and that's why i unlocked it with HTCDev, but if i were to do it all over again, i would have spend few more days to learn how to downgrade the Hboot and S-Off instead.. you can always flash newer Hboot later anyway..
So my advice, don't worry so much about the radio, or the Hboot version (you can tweak that later) at the moment, then downgrade the Hboot and S-Off it..
IMO it's much better than using HTC unlocker..

thank you guys for all your help and advice, finally after spending a couple of days,I successfully downgraded hboot 2.00.0002 to .98 one.
once again, thankyou all

I assume that you're revolutionary S-OFF by now, you can now easily upgrade on the latest re-engineered hboot

@doghous exactly !, I'm thinking of changing my hboot to the new re_engineered 2.00.0002 by vampire36, or if someone could suggest a better one.......

I have successfully S-Off my DS from HTC Unlock using the method by Skanob, it's pretty straight forward and noob-proof.. (not that you need that now ) and can be used to revert back to stock, S-On, Locked (not Re-locked) if you ever need to repair..
As for Hboot, i have upgraded the Hboot to Eng Hboot 7.00.1002 (the one you mentioned above) so that would be my recommendation, too!

Does anyone know what the differences between the different versions of ENG Hboot?
ENG v0.98.2000 vs. ENG v2.00.xxxx vs. ENG v7.xx.xxxx
Any benefits of using v2.00 or v7.xx over the v0.98?
Thx.

This one isn't an eng hboot. Better use 2.00.2002

A good question actually, even I have the same doubt and would really appreciate if someone could post the answer !
Sent from my HTC Desire S using xda premium

This is what I've gathered from forum trawling...
v0.98.xxxx: the original hboot for 1.x roms
Has the partitions: /system, /cache, /data (all ext3 or ext4)
Fastboot support, supports Revolutionary S-OFF
ENG v0.98.xxxx: engineering version of above
v2.00.2002: the new hboot for 2.x roms (Sense 3.0 etc.)
Has the partitions: /system, /system/lib, /cache, /data (all ext4)
NOT supported by Revolutionary
-> apparently, some Sense 3.0+ roms need this new /system/lib partition to work (stability issues), but I'm not sure which ones though...
->Note Revolutionary is NOT supported, so to S-OFF you need to downgrade using TacoRoot, ZergRush/Misc_versions, XTC clip or some other method.
ENG v2.00.xxxx: engineering version of above
RVL v6.98.1000: hboot that comes after you S-OFF with revolutionary
It is of a higher version number so breaks overflashing functionality, so you CANNOT revert to RUU (for warranty returns etc.)
-> Note: This can be overflashed with v6.98.2000 (OverARX), which then allows you to overflash a stock or engineered hboot.
v7.00.1002[\B]: modified 2.00.2000
NOT ENG BOOTLOADER
But are there any real life benefits of one over the other?

for example I have the Rev v6.98.1000 hboot, so what you mean is that I could have problems while flashing roms (occasionally), and hence I should change my hboot to the engineered one ?
Sent from my HTC Desire S using xda premium

I got really frustrated with being S-ON and found the HBOOT downgrade instructions dubious so I found someone in my area with an XTC CLIP device and S-Offed the bastard , don't care much about warranty at this point however.

@ste_vald well done there !, having an s-offed device is surely much better

No, you should be fine installing most of the ROM's (unless specified otherwise in the OP of the ROM).
However, ENG Hboot is recommended so that if required later you can easily flash new radio's / Hboot.

Thank you, but can't I flash radios on this rev hboot

No, i believe you can't! You will require an ENG Hboot...

Re-engineered HBOOT 2.00.002 and ICS.

Hi, guys, first of all I'm an absolute noob so bear with me if I didn't found all the answer even after having searched through the forum.
My big question is about the re-engineered HBOOT 2.00.002. I have a virginal Desire S, non s-off'ed and non rooted, HBOOT is the latest, that is 2.00.002. I want to load the latest official ICS rom from htc and, as I think I understood, HBOOT must be latest version, therefore non s-off since there is no way to s-off that version. But I also would like to just go to CM10 in the future.
Then I read about the re-engineered HBOOT 2.00.002. This HBOOT should give me s-off and the ability to load the ruu rom. Only catch is that you should re-partition the phone. And that's when things get weird. Does I need to do the re-partitioning before installing the ruu ICS rom after installing the re-engineered HBOOT? If so, in order to install the ruu ICS rom, does I need to have any working rom on the phone, that is, does I need to do the nandroid backup to have back my ginger bread 2.3.5 before installing the ruu ics rom?
And going on, currently there is any way to root the phone while on ICS htc stock rom?
But most important of all, what this re-enginnered hboot really is? The revoked/revolutionary mod only works on hboot versions before the 2.xxxx. Is this re-engineered hboot a 2.00.002 official hboot that has been modified to be s-off or is it a previous hboot s-off'ed via revolution but with a different version number?
Thank you all,
Vincent.

If I was you I would forget about the re-engineered HBOOT and just run the RUU and put ICS on your phone.
The re-engineered HBOOT is only for people who have S-Offed using the revolutionary method and have had trouble with the Android 4.0 Sense ROMs. You have absolutely no need to use it now.
If you want CM10 in the future then all you need to do is unlock your bootloader with htcdev, flash a new recovery (4EXT or CWM) and install CM10 from your custom recovery. You will be required to flash the boot.img file separately if you are S-On.

Hi Kavrocks, thank for your prompt answer. I'll surely follow your advice, it's the easiest way and my first goal is to get an easy ICS on my phone. My only doubt is about being able to get to cm10 or whatever else since no rooting hack has already been developed for the new ICS rom.
Do you think HTC will push updates on the new ICS rom or, being it for developer only, it will be just stuck to its original state?

Original.

By what I understand, now that an official ICS ROM is out and thus binary drivers are available, we should expect a fully working non-original ROM in a short time. How much time do you think it will take for the CMx developer to integrate the binaries into the CMx ROM?

Don't tell this my Desire S, HBOOT 2.00.002, S-ON, unlocked with stock ICS and root
Just do this:
- unlock your phone: www.htcdev.com
- Install stock ICS
- install a custom recovery using fastboot
- install superuser using custom recovery

Ok, I've succesfully got ICS on my Desire, eventhough I had to do a 'fastboot oem lock' to get past a 155 error. Now, would you please be so kind to tell me the exact filename of the superuser exploit that you have applied on ICS? I'm asking this to you because I've tried the 3.1.3 on GB2.3.5 and it always hang on 'waiting root access right'.
Thank you.
