Software update option missing - Desire 820 Q&A, Help & Troubleshooting

Hi i just bought an htc 820u and i went into settings > about and there is no software update option present there. Apparently phones bought from china dont have the software update option as i confirmed while talking with someone on htc website. My question would be how should i proceed to update to lollipop in that case? Should i flash a new rom? If yes can anyone give me a step by step tutorial please? Im used to flashing samsung roms but when it comes to htc i dont know anything.

Can I install a generic ROM to my Vodafone phone?

Hi guys
I'm wondering if I can install the generic European ROM here: http://www.htc.com/uk/SupportDownload.aspx?p_id=250&cat=2&dl_id=629
I didn't think I could, but it does say "This is a generic software update. Any additional software or settings provided by your mobile operator or company will be lost. If you require this customization, please contact your supplier first before upgrading." which implies that it might work.
I've seen methods with hotfixes which enable installation of the upgrade even if the ROM version is incorrect. Does anything like that work with this?
One issue is that my ROM version is 1.14.161.5 which doesn't seem to match any of the 1.19 ROMs that everyone else seems to have.
If I have to wait for an operator specific version, then where will I download that from once it's available? I've not seen anywhere on vodafone.co.uk that lists phone updates to be downloaded.
Thanks in advance
I tried but htc would not let me pass serial number page saying it wont suite my phone
INstall HSPL from the ROMs section and you should be ok

I bought HTC wildfire S with 2.3.3 and later i downloaded European update from here XDA, then my phone is upgraded to 2.3.5 , but now i got message that new update for OTA is available, my current software number is 2.13.401.3 and is there still new update for that?? my phone is already rooted, i m worried if this new update needs to be applied, should i have to root again or not??

If its not broken don't fix it I always say
Sent from my HTC_A510c
Actually it is better not to update , and the root won't go if you updated cuz it is more like permanent ... but it is better to flash CWM before updating if you were so pissed of the notification , as an overall , don't do it , it will add uneasily breeaked security unless you are ready=(root+CWM) which might require you to downgrade ...

[Q] Jelly Bean 4.1 update for Indian HTC One X

Hi there,
I have just got my hands on a indian version of One X 16gb through ebay, which is supposedly 3 months old (BOX SAYS ITS FOR INDIA WITH PRICE IN RUPEES AND MADE IN CHINA).
Software it is running is Android 4.0.4, HTC Sense 4.1, Software No. 2.17.707.3 by [email protected] Team
Now I tried to understand what has been said before and update my phone, It fids a uodate and downloads it but than displays the following message "we have identified that your phone may be running a modified version of system software. please revert your phone to official htc system software to update your phone. If you did not modify your system software contact us via support section htc.com"
I am not too technical and dont necessarily want to root my phone etc. ( I dont even know what it means). All I wanted was to improve the battery performance on the phone with new software. If there is no easy solution I am willing to go the whole length just give me the link to threads to follow (easy ones).
Regards,
Vik

The previous owner of HTC says that the phone is bought in T-mobile store and i can approved that because the packaging of my HTC is writing on the box it was the T-Mobile so i don't know its my phone T-mobile version or normal international version.
