Help about unlock bootloader and install oficial ROM

Please, I need some basic help:
I have a HTC One V, he's unlocked bootloader and root.
I unlocked my bootloader using a tutorial that is here Forum HTC One S. Same method.
Now I want to install ROM an official from another country (I want a European ROM).
I need to lock the bootloader again?
Can I install this ROM for HTC Sync?
Could anyone help me with this question? Thank you for your attention.
(Please do not move the question for another forum, because no one in another forum, and devices V and S are nearly equal.)
Thanks.

for official ROMs you need an RUU. whether or not a One S RUU will run on a One V device is unknown..
RUU's can be found in development section

But, and the question about bootloader:
I need lock bootloader again, or not?
HTC Sync install RUU, with bootloader unlock ?
Thanks !

yeah. i have done it like that.. you should be fine..
but if your flashing One S stuff on a One V there is no guarantee it will work
you take the risk flashing files meant for a different phone.

I downloaded the RUU original HTC One V.
I will install using the HTC Sync then, since i do not need S-ON again.
Thanks for help.

I think your supposed to install RUU's through fastboot

No brand HTC chacha

I am new to the forum, I greet all.
I would ask how I can remove the brand from a HTC Chacha, and manually update the firmware to the latest update for HTC Chacha.
Thank you.

Afaik up to this point there are no free methods. You can either:
1. Buy and XTC clip and do the S-OFF and the unbranding.
2. Buy an unlock code via internet or something for 10$.

Oh sorry lol, I have miss-read. I thought what you meant was locked to a specific carrier.
If it's unlocked then you can flash any ROM you want.

Can you tell me how to do or some tutorials online, because HTC can not find anything to inspire me confidence.

You can find a lot of tutorials here, in the Dev section for example, under HTC unlock thread. There you will understand how to flash CWM, root and then install a custom ROM.
I don't understand what you mean by "because HTC can not find anything to inspire me confidence".

noob question : can I flash *any* ROMs on 2.20 ?

hi guys,
I recently bought an AT&T One X w/ 2.20 firmware.
just wanted to know if I can flash any ROMs on the 2.20 firmware ? I'm a little confused between what is possible and what is not.
If I can flash ROMs, then I possibly dont want to root/unlock. If not, Can I unlock the 2.20 firmware using HTC-Dev (warranty voided) ? I cant seem to find One X in the dropdown at http://htcdev.com/bootloader/
Could somebody help ?

Nope. You can enjoy the phone as stock and that's all. No root, no custom roms

Simple, you can't do jack if your phone was shipped with 2.20.
Since AT&T is not allowing the bootloader to be unlocked by HTCDev.com. The workaround was to change the CID to SuperCID and fool the system, but root is needed to do that.
So you are out of luck until either a root is found for 2.20, or AT&T allows the bootloader to be unlocked. Or if S-Off is achieved.

OK. I got confused because there were all these articles that talked about unlocking the bootloader using HTCDev.
Nothing i didnt expect - any ideas on when HTC will allow bootloader unlock? Im assuming that the launch of One X+ makes this old enough to be let free

Hard to say, its all about what AT&T wants. All other carriers are bootloader unlockable out of the box. Its not based on any set policy, and AT&T has not made any announcement on when (if ever) they will allow it to be unlocked. They did a similar thing with the HTC Vivid. But allowed it to be unlocked about 3 months after the phone was released. That time period has long come and gone (One X was released in early May).

Once a phone is unlocked it remains unlocked permanently. Even if you change the ROM you do not need to buy a new code, the same code works, but as far as I know that won't be necessary. Please check your PM.

ARHD? That ROM isn't available for the Evita. You're either in the wrong forums or looking at the wrong ROM for your phone. If you flash an international ROM on the S4 One XL/Evita, you're going to hard brick the phone.

SIM lock survives ROM flashing. Check out the FAQ stickied to top of General, and my Index thread at top if Development for more on how to unlock bootloader, etc.

Remember you still need to use a sense rom to unlock then you can flash aosp, unless that doesnt apply to the endeavoru.

yea i get the phone with the stock rom ..
if not, i'll install ..
and what is "Unlock bootloader" ?
i new in this zone ..

Unlocked bootloader suspected, or no?

Have been a long time loyalist to LG phones over the past 4 years but am getting frustrated at the trend of bootloader locks with at&t handsets. I originally owned the G1 Dream and then the HTC Desire HD from HTC back in their heyday... Both were great phones to tinker with for the rom enthusiast. I have not bought an HTC phone since, because I could not trust their flippant camera choices. I ordered the LG G6 and sold it for the t mobile model, only to discover it may be fully locked down for a while, even with the t mobile model (fastboot commands stripped from the handset for some reason).
Guess I'm looking for a next gen phone with a killer camera and ability to flash to stock Android roms when they're available. Who here knows if I can expect this phone to be fully available for bootloader unlock to TWRP and rom support? If not, I just may end up selling my phone and wait for the Pixel 2 to be released otherwise.

Bootloader unlock with HTCDev will definitely be available (except for some carrier variants). SunShine support for gaining S-Off might or might not materialize.

I agree its almost a given its gonna happen. Its just HTC's thing.

From HTC's website http://www.htc.com/us/go/htc-u11-unlocked/
"The GSM Unlocked HTC U11 is the same great device as any HTC smartphone, but without unnecessary pre-loads or SIM restrictions. You'll experience more phone freedom than ever!
The GSM Unlocked edition on HTC.com allows you to pop in an activated SIM from the carrier of your choice* and change carriers at will, or to unlock the bootloader without voiding your warranty.
Your HTC warranty even covers bootloader unlocking on the HTC U11!
For more bootloader unlocking info, visit www.htcdev.com"

Also, there's been a working build of TWRP for this device for almost 2 months, so that shouldn't be a concern either .
Unfortunately you're going to have to find someone else to maintain it, though, since I can't afford to buy a U11.

That's a question for @jcase & @beaups

Alright, which one of y'all just kicked me?
Dunno yet, ordered one. We will research. That's all we know.

According to HTC chat no HTC U11 is unlocked via HTC dev. Hope they are wrong

Of course that's wrong.

I still wonder... Is there Unlocked and Unlocked ?
Unlocked to put any SIM card you want, that's granted.
But, is there models that are bootloader unlocked out of the box ?

There are SIM-locked versions of U11 that are sold by carriers, Sprint for sure and maybe some EMEA carrier variants.
No version will be bootloader unlocked out of the box, but all (including carrier ones) will be bootloader unlockable through HTCDev. Usually, only Verizon / EE have their handsets blacklisted from HTCDev, but Verizon doesn't have its own version of U11, not sure about EE.

Hey beaups, I know this isn't related to the thread, but idk how else to get in contact with you. Is there a way I can get in contact with you directly?

If this is real the bootloader is unlocked and S-off.

That's a tester device. Retail ones will be locked / S-on.

How long will it take for htcdev to offer unlocking the bootloader for the HTC U11?

No there's no chance to brick using HTC Dev to unlock. Just choose the "All other supported models" option at the bottom of the list.
