[Q] Downgrade hboot from 2.15 - HTC One S

Hi guys
How can I Downgrade my hboot from 2.15 to 1.14
I've got ota jb.
now i'm using viper 1.2.1 custom rom
and have: unlocked,rooted,supercid,,cwm,
I want to install ruu but first i must s-0ff......i tried to s-off but due to my hboot version s-off method didnt work
by the way I tried facepalm s-off method

I'm not sure you can now. I've seen a few people mention in the forums that if you didn't S off before doing the OTA, you'll have to wait for a new method as the exploit was patched. I could be wrong, check the S off thread.

You should be able to s off with 2.15 bootloader. I have done it no problems. Go through the s off process step by step, and for some reason it can matter what sort of ROM you have before going s off. So for example, try flashing the JB version of Viper, and then do S-Off (or one of the custom sense stock roms, ie latest t mobile, etc).

(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)

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 ??

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.

A good question actually, even I have the same doubt and would really appreciate if someone could post the answer !

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...

[Q] HBoot Question

Recently I rooted a friends One S just curious before I start flashing if I go from a sense rom to cyanogenmod or vice versa, Will I have to do anything with Hboot or can I switch between roms without any issues?
You can switch between roms , regardless of your Hboot. If you're on a higher Hboot after 1.09 I think then you have to fasboot flash the boot.IMG or use flash image GUI, even if you're restoring to a previous ROM. Doesn't matter if its cyanogenmod or a stock sense ROM. If you don't want to flash the boot.IMG then you can S-OFF http://forum.xda-developers.com/showthread.php?t=2155135

Thanks, thats what I needed to know.
I got a question regarding this topic:
My brother's One S is still on HBoot 1.09 and currently running an ICS ROM.
If he want to install a JB ROM, does he need to change his HBoot or anything else?
Because with my One X, I had to upgrade HBoot to be able to install newer ROMs.
Yes, Hboot update is required to install JB

thank you, is there an easier way than going back to stock and updating via OTA?
don't get hboot's and boot images mixed up
you can flash jb or ics or whatever on .09 and most likely will not have to flash boot images separate. that usually occurs on .13 or higher
i have .06 and flash everything including radios
obviously can't change hboots without s-oo

[q] s-off, 3.18 >>> 1.73 ruu?

So, I'm currently S-OFF, bootloader unlocked, SuperCID, etc. I was originally on the 1.73 base/RUU, and then upgraded using the 3.18 RUU. I would like to revert back to the 1.73 RUU. Since I'm S-OFF, can I simply run the 1.73 RUU (the older version) without doing anything fancy? I just plug my phone up and run the 1.73 RUU, even though it's a MUCH older RUU than the one I last used?
Thanks.
Yes.
Though I did not have supercid when I did it. You should be able to with s-off no problem.
If you're worried just fastboot OEM writecid "whatever your cid was originally" minus the ""

Ok, and do I need to relock my bootloader before running the RUU if I'm S-OFF?
No, don't

i have s-off with 3.18 firmwares on it running custom aosp roms. i find the 3.18 radio to be the best for at&t. since i have ruu i haven't reverted hboot or anything besides downgrading the touchscreen. if you run aosp roms i would flash the cm10 3.18 cwm flashable zip, since most use the older 2.20 radio.

I also have S-OFF , unlocked and go back and forth between the 3.18 and older RUU's , then flash radios that suit my area. At the time on 2.20, Clean Rom 5.1, with 3.18 radio. As I understand most posts on the deal, once S-OFF , you can do most anything as long as its a RUU for the particular phone , in this case the HTC one x Evita.

How to update from 1.85 to 2.20?

I have my phone rooted since the first days of having it.
Never taken OTA update so it's still on 1.85 and it's unlocked but S-ON.
Has TWRP 2.4.3.0 and custom kernel and ROM.
Wanted to try some new roms that require new 2.20 and S-OFF.
Found a method to root 2.20 and get S-OFF, but my question now is how to safely upgrade from my existing condition 1.85/S-ON to 2.20?
Thanks
Why don't you just s-off, then RUU to 3.18, flash TWRP 2.3.3.1, downgrade touchscreen firmware, and then you can flash whatever you want.

Agree. Just S-off now, then run the 3.18 RUU.
If you are on 1.85, 2.20 is just an obsolete and unnecessary middle step, at this point.
Thanks to you both. Would you point me to see off procedure for 1.85?
Or it is the same as for 2. 20?
Thanks again

Soff is the same regardless of software version. There's a sticky in the original android development section.

Can't SuperCID or S-OFF my HTC ONE S hboot 2.15

I have a HTC One S S4 thats Rooted and has Unlocked Bootloader on Hboot 2.15. I'm currently using TwistedKat 4.4.2 ROM.
I'm having issues trying to SuperCID & S-Off. I've followed this guide (http://forum.xda-developers.com/showthread.php?p=26516911#post26516911) to acheive SuperCID but thats not working for me. I've managed to go through all the steps with no issues, but when it comes to checking my CID, it stays at 02___001 doesn't change to 11111111.
I can't Facepalm S-Off as i need to SuperCID, which i'm having issues with. I've read that with Hboot 2.15, i'll have to use Moonshine S-Off but i can't do that as i don't have a matching firmware as i'm using TwistedKat 4.4.2 ROM.
I've searched around and there are a few people who are struggling to with Hboot 2.15.
Is there a way to fix this issue? I'm not sure if i've missed out any information for my phone but hope someone can help.
Thanks.
Anyone? Could really do with some help with this....
