[Q] how do I get OTA updates on a unlocked boot loader

As said in the title I have not rooted by phone just unlocked the boot loader I just got rid of the bloat ware that came with my device. However, having read some articles online I have come to realise that after doing the htc dev unlock, you do not get OTA updates anymore. Does anyone know how to get OTA updates?. I do no really want to root my device, but if its the only way now i will.
Any help is useful
thanks

S-Off. H/W you need root to S-Off or you can just relock your bootloader.

Prob bcuz you don't have the matching CID. Change your CID to HTC__Y13, and try again. Also, if you have debloated your phone, it is possible that it might be causing the issue.

If you have stock recovery kernel and rom then just change your cid to get OTA
No need to lock bootloader or to set s-on.
If not flash new rom (ruu.exe) (dont have to be on stock recovery firmware kernel and dont have to lock bootloader)
Change your CID and youre getting OTA

You don't need to re-lock the bootloader. I have S-OFF and unlocked bootloader and just installed the 2.24.401.1 OTA update. My CID was HTC__001 but I had to change it to HTC__Y13 to get the OTA update.

hey guys thanks for the help how do i change the cid ?

If you have S-off enter fastboot and type fastboot oem writecid HTC__Y13 when done reboot and check for updates and they should pop up.
Once downloaded and installed enter fastboot again and change cid back to what you had before.

[Q] S-off guide?

Ok so Im somewhat of a noob so I was wondering if any experts can help me out?
I wanted to get S-off on my HTC one so I can change my MID (http://forum.xda-developers.com/showthread.php?t=2322820)
I have a few problems with S-off?
Firstly, do I have to have my phone rooted to get s-off?
If yes, then I have to unlock the boot loader first and then root it right? If so can you give me a simple guide that shows how to unlock the bootloader followed by rooting?
Secondly, Can you give me a link to a SIMPLE guide to get s-off?

Yeah mine is Hboot 1.44.000 but before do the S-off tutorial, Should I unlock the bootloader and root the phone? or can I just do S-off?

Revone s-off can be run from a fully stock Rom, with no need to unlock the bootloader or rooting before. (Following the guide linked in previous post)

Using adb commands while booted in the stock Rom.
No you can be fully stock while using the revone guide if you don't want to unlock via the HTCdev method.
You only need to be rooted if you want to s-off without the use of a pc (using terminal emulator on your device).

I don't think you should be messing with S-Off when you don't really know what you're doing and haven't even got adb installed
Also, changing your MID can be risky and is a lot trickier than simple S-Off, which you should know how to do. I know someone who bricked their phone changing the MID.

I guess you are right. My knowledge is limited and I don't wont to brick my phone.
But on the other hand, I really need the 4.2.2 update. I have some problems with the current one.
Anyways, When I use fastboot, I get CID HTC__001.
Thats USA so I'm guessing it'll be a while for the update to come out huh? But my phone is not locked to any carrier.
How long do you think itll take before update OTA is available?
Thanks alot man

what is your device's MID ..? you don't have to mess with it if it's already PN0710000, changing the CID to HTC__Y13 should be enough to get 4.2.2 .. you can get your MID by typing fastboot getvar mid adb command ..

Thank you so much.
I started doing what you said before you put this post.
I did the same thing but in step 3 I just changed the CID to HTC__Y13 instead of fastboot oem writecid 11111111.
When I rebooted I got the update for 4.2.2 and downloaded it too. But when installing it reboots into recovery and says aborted.
Do I have to to steps 4 5 6 7 8 or is there way to just install the downloaded OTA?

it's better to follow the sequence .. a clean RUU install would solve any issues your device currently have ..

You need to be S-OFF to manually flash the OTA file through the stock recovery, or to change CID.
So unless you are willing to s-off your device, the only other option is to wait for the update to be pushed by HTC direct to your phone as usual.

You can change to whatever CID you have but you MUST have same software version as your CID to receive OTA...
That means:
fastboot getvar cid = adb shell getprop ro.cid

you don't need to relock bootloader as you S-OFF to receive/apply OTA but completely stock is a MUST including stock recovery

Not really, With S-ON you can flash signed ruu of same or higher version with bootloader LOCKED or RE-LOCKED.
S-OFF is only needed to flash unsigned RUU or for downgrading, and with S-OFF you can flash a RUU with a locked/relocked or unlocked bootloader.

DId you MD5 check the ruu before flashing? error 152 is for ''image error'' and the four triangles with exclamation marks means the ruu did not flash completely.
Edit: So you were on 4.19.401.11 before flashing 4.19.401.9 ? You can't downgrade with S-ON

DId you MD5 check the ruu before flashing? error 152 is for ''image error'' and the four triangles with exclamation marks means the ruu did not flash completely.

The issue was that before flashing the RUU, the phone firmware was higher than the RUU firmware. The phone was 4.19.401.11 while the RUU is 4.19.401.9. S-OFF is required to flash a lower firmware
Your solution:
1) Unlock bootloader
2) Flash TWRP 2.6.3.3
3) adb sideload ARHD
4) S-OFF using Firewater
5) Then relock/lock the bootloader. Remove TAMPERED if you want. Then flash the RUU
(you can set the bootloader to LOCKED and remove the TAMPERED flag if S-OFF)

OP is stuck in ruu mode after an incomplete ruu flash from 4.19.401.11 to 4.19.401.9. S-ON, bootloader relocked (not able to unlock again). THe only option in bootloader is RUU in orange.

Yes, @nkk71 might have an idea. Im just sharing what I know- If you cannot get into fastboot also, you really have a serious problem. Your only option (not 100% sure) is an RUU based on 4.19.401.11, which doesn't currently exist. If there is another solution, I don't know. But I think you will have to wait for an RUU based on your version.

That screenshot does not look nice!
you're firmware is in limbo... from the looks of it, you did the first flash, but didn't do the second flash.
So first make sure the RUU you have is not corrupt, the MD5 should be 9AD4111CE86981E3DFFCCE6D9EE80551
Second, do you still have a custom recovery installed, or a rooted ROM?

I've stock recovery , i'm sure
Before i've a stock rom by grureset
I can use ruu 4.19.401.9? Or can i flash rom.zip with fastboot?
Inviato dal mio GT-N8000 usando XDA Premium HD app

Finally i've found a solution!!!!
i've downloaded the ota 4.19.401.11 extract firmware.zip
flash it with fastboot 2 times and now i can access to bootloader!!
Thanks for support
