Install a custom ROM with HTC official unlock

Can anyone please tell me how to install a custom ROM onto my Desire S with the bootloader unlocked via HTC Dev and S-ON?
My guess is that you install CWMR and flash it via that. But you need root access to do that, I thought unlocking the bootloader was meant to eliminate this.
Also, I've been reading that people are having issues installing ROMs this way, they are experiencing a hang at the HTC logo on boot.
Any information will be greatly appreciated, thank you.

After you flash the custom ROM using CWM, you then have to extract the boot.img file from the ROM.zip file and manually flash it in FASTBOOT mode. That is the nature of the unlocked bootloader. The boot partition is not mounted R/W in recovery mode, it is only mounted R/W when you are in bootloader FASTBOOT mode.

Ok, from reading yours and various other posts in the forum, I need to do the following to install a custom ROM with an unlocked bootloader and S-ON:
1. Unlock bootloader via HTC's website
2. Root phone (with gingerbreak apk?)
3. Install CWM via ROM manager
4. Backup existing ROM with CWM and backup files with titanium
5. Install ROM via CWM (wipe data, wipe cache, install ROM)
6. Flash boot.img (HBOOT, fastboot, and flash image)
7.Reboot into cyanogenmod
If I have anything wrong, please let me know. Thanks.

Step 2 and 3 are not necessary. After you Unlock the bootloader, you could then simply flash ClockworkMod in FASTBOOT mode.
1. Unlock bootloader.
2. Flash CWM image in FASTBOOT mode.
3. Backup existing ROM with CWM.
etc.

Thanks for yours posts

I would also like to thank you tpbklake, haven't tried it yet, but I'm sure it'll work!

I will be getting a new unbranded Desire S in a couple of days,
In case it will be running HBOOT 2.00.0002 with S-ON will I be still able to flash a custom rom on the device? AKAIK S-ON only protects the radio from being modified.
sorry, I'm new to this
edit: okay i read its not possible to flash a custom rom, but then what can i do when I rooted and flashed a custom recovery?

Either isn't possible without s-off, look at the index thread, it's all there.
Swyped from my desire s running damn sweet ice cream

I'm on an Inc2 but since it's basically the same I hope this applies...
I'm in the same position as the OP with the newly unlocked bootloader via HTC.
I flashed cwm through fastboot but now I can't reflash through ROM Manager. I installed both SuperUser and BusyBox but both point the finger at eachother saying the other needs to be installed. What am I missing??

Download the latest su-3.0.x.zip file. Then boot into CWM recovery and install this zip file. This will root the current ROM you have installed and then ROM Manager and BusyBox will both be happy.

@korenisko
So you unlocked via HTC dev, flashed custom recovery, wiped all partitions, flashed cyanogenmod, rebooted into fastboot, flashed boot.img via fastboot (fastboot flash boot /pathtobootimg/boot.img, if i recall correctly) and then you were able to boot into cyanogen?
I did exactly these steps (only with 4ext instead of cwm, which shouldn't affect the result) and was stuck with the white bootscreen and no adb logcat output whatsoever.
Currently I am back on a prerooted official RUU (2.3.3), but it still performs really bad and I would like to have cyanogenmod.
Btw: I have a Desire S, hboot 2.00.0002, S-ON, no carrier branding.

The currect way
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 Endymon
I read many thread and i understood that the curret way to do this is:
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.30.085AU_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
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.
Now i can download the custom Rom and install using this way:

Is It right?

Hello, I just want to share my experience on how i managed to S-OFF my phone. My main problem was that I had the latest ruu on 2.10.401.8 and couldnt downgrade. Even though i unlocked the bootloader using the htcdev .bin file I couldnt install the proper recovery (clockwork mod) nor a previous ruu. So here is what I did.
I first unlocked the phone using the htcdev.
Then I followed those pretty 7 steps mentioned on prev post.
and changed my version to a prev one.
I r e l o c k e d my phone using htc supertool and
clicked my 1.47 ruu exe file. That worked and it downgraded my phone.
After that it was a piece of cake to use the revolutionary tool to S-OFF.
Thanks all the xda community for the infos i got and managed to do it....

bro...i hit thanks!

I was actually wondering about the issue of having to flash the boot.img if restoring a TWRP backup. I assumed that it would have to be flashed via fastboot, since boot.img is obviously needed but can't be accessed by recovery on the 1.14 hboot. But haven't seen that discussed or confirmed here. Doesn't actually apply to my One X, since I'm on the old hboot. More just wondering academically.
Seems like the OP has taken the route of running the RUU. But if you ever need the boot.img for a stock ROM, many of the stock ROMs are posted in Development. So you can download the right one, and pull boot.img from it.

Yes you need to flash boot.img when restoring a backup on hboot 1.14.

Thanks for the tips guys, I also used this just now to unroot my phone and return it to bone-stock. I used the All-in-one tool to relock the bootloader and got the same error message that OP got, but after rebooting into the bootloader it said Re-Locked. Then downloaded HTC Sync and the 2.20 RUU and ran it. Took 15 minutes total and my phone looks stock, unless of course some busybody at AT&T decides to check the bootloader.
I am returning my One X and buying a One X + tomorrow morning.
EDIT: Oh and in case anyone is confused, you DO NOT need to flash boot.img in order to flash the 2.20 RUU.

i heard people say that they flashed the twrp boot backup in fastboot and it worked the same as flashing the boot from rom.zip in the ruu. i prefer the ruu method for going back to stock, just seems more official imo.

[Q] Need info about bootloader mode and other stuff

Hi im new to htc and bootloader and all this stuff.
when i had galaxy s2 i knew everything about it. (download, recovery)
so here is what i need to know:
1.can i create a NAND backup of a stock rom and restore to it if i have s-on?
2.what doe's ***tampered*** in bootloader mode means?
3.when i flash a custom rom and i extract the boot.img do i have to remove it from the zip file itself?

1. No, if you have S-ON you can't create a NAND backup as you don't have a custom recovery.
2. ***TAMPERED*** means that an app or apps have gone into your /system/ partition, thereby triggering the tampered flag. You can remove this message by running a HTC RUU.
3. No, you first flash the zip file with the boot.img inside, then flash the boot.img in the bootloader. fastboot flash boot boot.img

1.i do have a custom recovery which i flashed with all in one kit. (i was able to flash it because i unlocked the bootloader but i dont know what s-off means and also supercid)
so can i do a nand backup of a stock rom and restore to it?
and i also wanted to know how to s-off and what are the differences between s-off and supercid?

Then yes you can make a backup and restore later. Just always full wipe, cache and dalvik cache wipe.
As far as flashing kernels/boot.img, if you are < hboot 1.13 then just flash via recovery. If your hboot is > or = to hboot 1.13tjen flash via fastboot or flash img GUI (available in the play store and in various threads).
And as of right now there is no s-off for the one s.

S-Off means you have full access to all firmware partitions of the phone (I think, correct me if Im wrong). You can unlock the boot loader to gain access to the relevant partitions to flash a custom ROM even with S-ON.
The phone CID just represents the region it is from. For example HTC_TMOUS is for the One S used on the US T-Mobile network. When the phone checks for updates, it only downloads the one's relevant to the CID. SuperCID is 111111111 and represents the "developer" region you can download or run any update on a One S with super CID.

Yes, you can make nand backups and restore them if you have a custom recovery. You don't need to have s-off for that but you do need to have your bootloader unlocked. Depending on your hboot version, restoring a nand backup will not restore your boot image. (1.09 and below will, 1.13 and up won't.) We do now have the means to downgrade hboot tho.
You get the *tampered* line if your recovery is unsigned. When you use a custom rom, you will most likely also get a red warning text over your boot splash. It's normal.
You have to extract the boot image from the rom zip and flash it in fastboot before you boot the new rom. This may even be before you flash the new rom. You can leave the rom zip unchanged and flash it in recovery.

Correct. On old hboots, pretty much everything except sbl and hboot is writable in recovery or even while fully booted. On newer hboots, most is read-only. Boot image can be flashed in fastboot but radio and other stuff can not.

The mksh root request is a known thing. You can search the forums for it to read some opinions. As far as I know not yet properly explained why it happens but harmless. It is not related to getting stuck in recovery, altho I have no idea what caused that for you.

[Q] S3 Villec2 OTA update

I've got an HTC One S [s3]. CID is HTC__622 Asia HK
I have unlocked bootloader, TWRP recovery and superSU loaded as well as Rom Manger
Tonight there is an OTA update available. So I want to use it. I downloaded it and
ran command: fastboot oem lock
and tried to run the update. It just keeps booting into my fastboot menu.
I heard that I need to install stock recovery tfor this to work but I don't know where I can find it.
I do have a reovery_signed.img file that I saved from somewhere that is 5,957 kb. Not sure if I flash that if it would give me stock recovery.
Can someone give me a direction to go. I have spent last 12 hours just reading stuff and still don't know what to do.

Htc_asia_hk Stock Recovery File
Does anyone know where I can find the stock recovery file for my One S [S3]

The problem is I didn't take a backup before I unlocked my bootloader and flashed twrp recovery so I don't have a stock recovery to go back to.
The RUU for HTC__044 has a different CID and won't work on my device unless I can extract just the stock recovery from the RUU without having to install it. Is that possible?

3. Enter fastboot and run the RUU for your phone
Your phone will then be just as it was when you bought it and then you can run the OTA. Make sure you find the right RUU for your phone. I have been searchiing for one for days and couldnt find it. Hope this helped

Maybe a stock recovery of JB would be enough.

Hello guys,
Try this:
Step 1: relock the bootloader (start your phone in fastboot, open cmd, got to folder where are fastboot files, type "fastboot oem lock" )
Step 2: find your desired stock jb or ics online. http://filesdownload.net/showthread.php?70-HTC-One-S-(-RUU_VILLE-)-(-RUU_VILLEC2-)
Step 3: connect your phone to the pc in fastboot (make sure you have the htc drivers installed).
Step 4: run the RUU or stock file as an exe. An installation guide will follow, just follow it through.
Step 5: Now you are in stock ROM
It should work after this!
On my HTC One S [S3] , CID HTC_032 works

splanet.info has something interesting
At least ota is there for htc__622

After I locked my bootloader and tried running the OTA update I tried a few things that didn't work.
But what did work for me was when I unlocked bootloader again
And used Hasoon's Toolkit for One S
and reflashed the recovery file. I used the recovery_signed.img file (5,957 kb) that I had saved from when I was rooting it the first time and renamed it to a one word name per Hasoon's instructions, then flashed it.
Then I relocked bootloader and did a factory reset and ran the OTA update and it worked.
I was lucky that I had that recovery file saved. Still not sure where I got it from. But one thing for sure is that it was hard to find a RUU file for my CID. Hasoon's toolkit does have links to a website with a list of RUUs on it but mine wasn't on the list.
If you want me to email you my signed_recovery.img file send me a pm with your email address and I'll send it.

[GUIDE] Back to Stock ICS for k2u & k2ul with S-Off

Back to Stock ICS for k2u & k2ul with S-Off
Hi there, as there are different news, we will get one more major update, there is a need to get back to the stock rom, cause otherwise the update will fail. Or maybe you want to sell your device or need to return for warranty, so you also need a stock phone.
And there is nothing more stock out there, than a RUU. But as we have no Jelly Bean RUU, we need to get the ICS RUU running to downgrade hboot first!
So we provide here an almost easy way to go to this condition and you only have to follow these steps, but do it careful, cause we need to downgrade hboot for that and this is very dangerous for your phone, if you are doing something wrong!
This guide is provided to you, with the help of Matlevo12, who made the files you need for downgrading hboot and tested the way. So give him a thanks for it!
This only works for "free" phones (unbranded) or if you have Supercid.

Notice:
- This guide is for european k2u & k2ul. Don't do this on other HTC One SV devices, this will brick your phone.
- Be careful and download the correct file, check the md5 sum to get sure, the download is not corrupted.
- Make a backup of important files, before you do this, they are lost afterwards!
- This will not reset your CID, if you have changed it to SuperCID. So if you have SuperCID, follow this guide to change it back before you doing this! Your phone must be unbranded then.

Don't do this, if you are not experienced enough for it. You will do this on your own risk and we are not responsible for bricked devices!!!
Requirements:
- a phone with S-Off -> yes, you need S-Off (if you don't have it, look here for ICS and there for JB to get it.)
- the correct file for downgrading hboot
- the correct RUU for your device
- some time and coffee and some knowledge about fastboot commands

How to:
To downgrade hboot:
1.) Download the fitting zip file for your device
2.) Rename the file to PL80IMG.zip
3.) Copy it to your sdcard (external not internal)
4.) Reboot into bootloader and hit volume up when prompted
Click to expand...
Click to collapse
You maybe need to go to Settings -> Power first and untick the Fast boot (scroll down, last point on the page) that you can boot into bootloader!
To boot into bootloader:
If your phone is off, you need to power on & hold vol- at the same time.
Now the hboot should be downgraded to hboot 1.0 and most tricky part is done.
To flash RUU:
5.) Reboot your phone and connect it to pc
6.) Run the downloaded RUU.exe (you maybe have to start it as administrator) and follow the steps provided by HTC
If the RUU won't flash, relock your bootloader with fastboot cmd:
Code:
fastboot oem lock
Click to expand...
Click to collapse
After the RUU was running through you have stock ICS boot.img, recovery and system files installed. You are still S-Off, but with a "*** LOCKED ***" bootloader.
If you wanna get S-On, follow now step 7.) & 8.).
If you wanna update, now you can restart your phone and search for updates. Install one by one (first will be the jb updates) until you don't get update offers anymore.
If you want to get your device S-On:
7.) Connect your phone to pc and boot into fastboot mode.
8.) Open fastboot command window on your pc and type the following command:
Code:
fastboot oem writesecureflag 3
Click to expand...
Click to collapse
Now you should be S-On.

CID error
Can anyone help me?
It is normal to use just a little leg and can't flash rom.
How should I do now?
Thanks much.

When do you get that cid error ?
What cid are you ?

my CID is Orange1 or something similar, can I still use this method to be able to get myself an unbranded version of JB on the device?

Conan_troutman :
Well no, use the "unbrand your phone..." guide in the same section.

I think this only work for "free" phones or if you have supercid.

Your phone is branded, unbrand it first if you want to, or downgrade using files from your brand's ruu.
Why do you want to downgrade ?

Thanks much

Thanks much again for reply.
At first, I must say that my English is not good enough, sorry.
Downgrade just for 2 way recording, because I need this function very much on the business. When 4.0.4, it's ok, but update to 4.1.2 it is unable to use.
Now, my phone can also be used, but not smooth.
How to unbrand it (sorry, Idon't understand what does branded mean) or what Ican do now?
Dear Matlevo12, Thanks very much.

S-off and RUU update went smooth but I no longer can enter Recovery menu. It shows an exclamation mark surounded by red triangle.
k2ul unbranded phone here and used RUU update file acording to my phone model.

Which S-off?
I upgraded to JB and want to bring ICS back. Old.splatterhand, you said we need S-off so which one do I need please?
Thanks a lot for sharing! :good:

As you are on JB you must use Moonshine S-off.

Thank you! Hope it will work...

Hello all, sorry for bothering you again old.splatterhand, but before doing it I want to be sure I'm understanding things in the right way.
So after step 6, I will be done and should have ICS back, that's it? Thanks

Yes, it's pretty clear :

Alright then, thank you Matlevo12!

Pure JB Rom, Kernel, Recovery, etc.
I got the JB stock Rom, Kernel, Recovery, etc. Just got to place it on your external sdcard. Its completely fresh without touching it. Just like you gotit from the box. This is for k2_cl, it may work for others but not tested. Need atleast 1.02 gigs available on external sdcard. Once placed there just boot into custom recovery. I used TWRP and I recommend it. Not a fan of CWM. Once in recovery just click on restore then select the pure JB folder. It comes with MD5 files so be sure to check the verification box so when doing this it will confirm its integrity prior to proceeding further. After verification it will proceed on and wipe everything out as it restores. Then reboot. Keep in mind that this is a fresh 4.1.2 JB stock. You will lose root but you can easily get it back by downloading supersu on Google play. Voila. Will have to upload tonight then will share resource on here. Once available have at it. I don't request credit for it or anything. Just want it out there for people who messed there phone up or failed to get a copy for themselves.

There are already copies of this for k2_cl in old.splatterhand's thread in original android development
