HTC restricting those with s-off?

I was lucky enough to have a s-off/supercid unit, was previously on a carrier ROM then flashed the 1.29.401.7 RUU. So today I see .11 has been released OTA and go to update. It downloads fine, verifies the update then this

I've tried it three times upon three reboots and same message. I'm not sure if it is HTCDev unlocked but it isn't rooted
Have any other s-off owners encountered this? If not, then move along and ignore me...

Where did you get an s-off/supercid handset from?

Got chosen to write a series of posts about the One X for a blog sponsored by the carrier, part of that is a free phone. Oh and I'm sure the fact we got it a week or two ahead of the local launch helped as well

Might be best you stop trying to do any updates bro, and make yourself known to the good folks in this thread

Posted in that thread many times offering any help, noticed a post in there replying to another guy with s-off and apparently we're not much help anyway

I see. All good, just thought you might have held the holy grail...
Actually, you could be of help. Send me your phone and I'll send mine, that'd be a HUGE help!!

Well the thing is. Your phone maybe SuperCID but the SN still belongs to a branded phone. Maybe this makes the confusen... Just wait for the full RUU and flash that one.

Hmz, just checked the firmware.zip and seen this command: erasebcid: 1
NVM, this command is also present in older OTA.

What do you mean by SN?
Going to try and get someone I know to try and replicate it, s-off with Asia unlocked unit

Just got this reply from HTC. Firstly I am not rooted (at least last time I checked). Secondly I am going to check whether it is HTCDev unlocked when I get home. Does being HTCDev unlocked mean I cannot get OTA updates?
Thanks for contacting HTC.
We understand that you have some concern with regard to updating your phone’s software. Please allow us to discuss your concern and assist you.
HTC manufactures each Android phone to the exact specifications as set by Google, the platform’s developer. The partner mobile operators who distribute a said phone model then customize the software for use in their respective networks. This is why the phone’s warranty is automatically void if the default phone software has been modified in any way.
Based on your email, you have rooted your phone and installed custom or modified software. In this case, please understand that you will not be able to receive or install the latest software that will be release by your dealer. Any updates you will be receiving will come from the developer of the modified software. If you want to update your HTC One X software, please contact the developer of the European RUU.
The only way you can restore the phone’s original software is to go through your dealer where you purchased the phone or its authorized service center and have it reinstalled for a fee. This is needed so you can download and install the latest software released by your dealer. Please be advised that according to the dealer’s terms and conditions, any modification to the default phone software automatically voids the warranty. However, if you have the software reinstalled by an authorized service center, you will still have a shorter service warranty in effect (the standard warranty being already voided).
Important: Please be advised that HTC distributes handsets through our partner mobile operators which we have contracts with. Our partner mobile operators also determine the software and specifications for the particular handset model they are distributing. Any queries regarding repair, assessments, replacements, upgrades and warranty claims are best discussed with your authorized dealer. Please be reminded to back up your phone’s data before going to your dealer.

No, it does not.

^ Thought that might be the case. I am locked and I am not rooted, yet this occurs.
Plus my reply to HTC's above message ^^^
Hi,
In reply to your reply... my One X is s-off/SuperCID, meaning I can flash whatever RUU I wish and it should get OTA updates for that region, as it did (except it fails). As far as I am concerned there is no trace on the phone linking it back to Telecom NZ at all, except possibly the IMEI - does this affect the installation of OTA updates?
I have not HTCDev unlocked, nor rooted the phone. It is merely s-off, thanks to HTC most likely. Within the bootloader it says I am locked, not unlocked or relocked, and apps like superuser or mybackup root do not work - as expected. The 1.29.401.7 RUU is signed by HTC and comes from HTC themselves, it isn't something from a custom ROM developer, the RUU I ran - and currently have on my phone - is 100% stock Android 4/Sense 4.0.
What I am trying to say, I effectively have an unlocked European One X (that is s-off) yet fails to install European OTAs because apparently I have "modified software". Doesn't sound right if you ask me.
Cheers

You're emailing first line support at HTC, who probably have NO idea what being S-OFF is, and are just going to give you a generic answer to anything you send them. Don't waste your time
You said you changed your CID to HTC__001 in a past post - have you changed it back to Super CID? If not, do it and try again
Otherwise, just flash the RUU. And for the record there's someone in the UK with an S-OFF handset who got .11 OTA with no issues (and has never changed the CID at any point)

According to CIDGetter I am still SuperCID, scrolling down to ro.aa.maincid is HTC_001, the update region I presume, so I have no need to change it back to SuperCID
Would really prefer update OTA (or flash the update.zip, how do I do this? Im sure I've downloaded it enough times) since I can't be bothered unlocking and rooting for titanium backup
Good to hear it's perhaps just me then

You don't need to unlock to backup, there's a thread in general on how to do it via adb

Cheers for the tip, forgot about that
As for the guy that did manage to update, was he originally HTC_001 (update region) anyway? I still haven't ruled out that carrier and asia phones will have trouble once s-off is achieved, they flash the EU RUU and expect OTA updates only to get the same problem as me

Nope, he's never touched it so it was always 11111111 - the ro.aa.maincid is irrelevent as it's not the CID
Try this:
1. Connect in fastboot
2. Run 'fastboot getvar cid' and see what comes up
If it's 11111111 you have Super CID, if it's HTC_001 it's not a real CID, if it's HTC__001 then you have the unbranded EU CID

Think it's meant to be HTC__001 not HTC_001 ie 2 underscores.

[Q] How can reset or clear Relocked flag on bootloader

Hi everyone,
I have a One X with S-OFF .
How can I reset Relocked flag.
I hate to see "Relocked" on bootloader.

You cannot get rid of it, any way you never see it. How often do you enter recovery.
Sent from my fingers

at least twice a day

Does not anybody know?
can i replace the "mmcblk0p4" block with "locked" mmcblk0p4 block from another One x ? What happens if I try..
Is Relocked flag in this block?

Save yourself a brick and live with relocked......

thanks for your reply
maybe, i save myself a brick but don't live with relocked......:crying:
because, bluetooth does not work. I need to send the phone for service. but it was out of warranty.
i think.. maybe fix it and re-covered by warranty.
I guess I'm wrong.

The only s-off phones that successfully got the bootloader back to locked were bricked to the max.

my HOX is already S-OFF.
Once the RUU is installed, but it did not resolve.
There can be phones like the ONE XL or ONE m7
Why can not the ONE X.
I know the processor is different. but still must be a way

Please read carefully. The phones that had s-off and wanted to lock the bootloader got BRICKED ! a ruu does not lock the bootloader.
It's because of the tegra crap !.

ok. I understood.

Yeah sowwy

I am back to S-ON and I will send phone to service.
and when it comes back to sell it.
and an even more stay from tegra.

Hello Guys! I would like to overwrite the flag relocked to locked on my HTC. My H.One no longer has any trace of root, boot recovery is the original factory and the current state of HTC's S-ON. Everything perfect! Original RUU factory, no bug, it's all right. My only fear is not guaranteed to be valid, for the simple fact that the bootloader be "relocked". How can I override this? Without changing the S-On to S-Off?

S-On, Relock, and unroot.

Back on the M7, there was this incredible software that not only returned the phone to S-On, but also lock the bootloader in such a way that it doesn't say "Relocked" but Actually just "Locked". Is there such a method for the M9?

Yes, there are methods to return to "locked" instead of "relocked" and to change your software status back to "Original" but if you have made modifications to your phone, going back to s-on is a bad idea, potentially dangerous, and not necessary. Doing it is easy, but why would you want to?

What if someone wants to make use of a warranty repair, and it is important for him to make sure that the phone does not appeared to be "tampered"?

I have sent HTC phones back for repair s-off and had no issues. HTC has explicitly stated that modded phones are eligible for Uh-Oh and similar protection, though not all CSRs got that memo.
If you feel you must go back to s-on for warranty repair, you need to follow the return-to-stock guides exactly or you risk brickage. You will have to do this manually; I am not aware of a toolkit that could do this and would never use it if there were. Too many variables on going back to full stock (different bases, etc.).

[M8] Bootloader/root + warranty

Hello,
I ve got new M8 few day ago, and want to root it, I know that unlocking bootloader MIGHT void warranty depending on carrier, but Ive seen something about "relocking" it while S-Off - not "re-locked" sign but actually "locked". So there is actually no traces of unlocking/rooting.
Is that possible? And if, is that possible for "un-voiding" warranty?

"It depends"
It depends on whether your warranty is through the carrier, or HTC. And it may even depend on what region/country, etc.
Yes, you can make the IMEI say LOCKED. And if that is what they are checking, there will be no trace of it being bootloader unlocked.
But also remember that HTC has a record of you unlocking the bootloader via HTCDev.com (linked to your device's IMEI) and they can check that as well.
Carriers probably won't go that length. HTC may or may not. I'd say its "probably" okay (HTC will honor warranty) to have bootloader LOCKED. But its not a sure thing, for the reason stated above.
Are you sure you have a warranty to begin with? The phone came out over 2-1/2 years ago. I'd be surprised if they were still selling this as "new" with a valid warranty, and its not refurbished, second hand, etc.

Well, I don't have it through carrier nor HTC, just e-shop, and I hope it is new, seems like new (got last one) So, theoretically, I can unlock bootloader + root, and when I need to do warranty repair just to "lock" it same as unlocking it, or for "locked" do I always need S-Off? And also,how do I get that S-off?

1. What is difference between "locked" and "re-locked", isn't that technically the same?
2. one "license" in Sunshine is for 1 device ("unlimited" S-On/Off locks/unlocks) of 1 S-Off unlock?

1) RELOCKED by definition means you previously unlocked the bootloader, then relocked it. It will actually say RELOCKED on the bootloader screen. This is not what you want, if you want HTC to think the phone has never been bootloader unlocked. The main reason for making it RELOCKED, is to run RUU or signed firmware (will not flash if bootloader is unlocked, unless you have s-off). You can make it RELOCKED while s-on, with the command: fastboot oem lock
LOCKED is the condition you want, if you want to make the bootloader look like you never unlocked it. S-off is required to make it LOCKED; using the guide I linked in my past post. You can basically think of this as a hack.
2) The license is for the device. From what I understand, you should be able to use the app to s-off, unlock the bootloader as much as you want; even if its been relocked or made s-on again.

I don't use Snapchat, so I have no idea on that. Apps may look for root, on an app-specific basis. For instance, Pokémon Go won't run on rooted devices (and don't think methods to "hide" root work in this case) to prevent players from cheating.

For Pokémon Go, no. I haven't seen any workaround, except to unroot. But are you asking about Pokémon, in particular? If you are asking about apps in general (which look for root), and whether you can hide root or not; its going to vary on an app by app basis, and I can't really answer that.

Unroot with SuperSU will still show the system as "modified".
Easy way to unroot, is make a TWRP backup before you root. Then you can just restore that backup, to "unroot" (you are restoring the ROM that was never rooted in the first place).

In addition: it has all the same features as permanent S-OFF, with exception of the ability to use custom hboot/aboot. Once you reboot into Android or Recovery, the device will reset back S-ON, so be careful what you do, once you achieved S-OFF.
Permanent S-OFF is to dangerous - and much more risky - on those new devices as the U11 and all more recent ones.

Wouldn't recommend SuperCID anymore, as you won't be able to receive OTAs any longer - yes they changed that as well. S-OFF is only needed to change CID and thus the specific software you're running, or to flash unsigned firmware. No more no less to it actually.
And there's no actual recovery partition anymore, due to treble. Instead stock recovery shares its partition with the respective boot.img. Thus I guess TWRP might be flashed as recovery_ramdisk, or as a TWRP patched boot image - we'll see when it's out and available though.
Sent from my HTC U11 using XDA Labs

S-off gives you complete control over YOUR device. You don't necessarily need to receive OTA's if you're S-off. You can flash your firmware on your schedule, not when the carrier or manufacturer says it's ready. Flash it when you're ready. Flash what you want, when you want. If the option is there, I'm getting S-off every time.
Do your homework, research and learn. If you're too lazy to do your due diligence, don't S-off. You can truly brick your phone if you're not 100% sure of what you're doing.
If you're going to just flash ROMs or just get root access but stay stock otherwise, no need to S-off. If you want complete control over flashing everything , go S-off.
But remember with great power comes great responsibility.

Beyond flashing random firmwares willy-nilly, what's the actual point of this when all U12+ ships unlocked (at least here, in the US)...? I really don't see any reason now.

You need to be sure you went to HTC Dev and unlocked your bootloader first. After that you need to be rooted.
If you have both of those steps done and you're getting errors, go to: https://therootninja.zendesk.com/hc/en-us and check out how to troubleshoot, and send in a support ticket.

Temp. S-Off helped me to fix my Slot b, it seemed slot b was corrupt, it wouldn't boot as if there wasn't a ROM on it so reverting back to the old 1.15 ROM and taking the 1.21 OTA seemed to fix it. Seemless updates worked and i am currently back on slot b finally. I tried everything beforehand and nothing would work except this.

Thanks, used sunshine to convert u12+ china to emea ROM

answer from the support:
HTC designed the u12+ to only support temp s-off, all phones after and including the 11 have been this way

I tried to achieve S-Off with 1.30.401.2 but it takes more than 10 minutes and afterwards the phone boots into the system and not bootloader/download mode. Any thoughts?

I just tried it on 1.30 and it is working for me. I have no advice other than that, sorry.
