[Q] One X and question on firmware and HTC Dev bootloader unlocking

I am on my way to go and buy two At&t One x. They are currently still running 1.73 thankfully. Im not new to rooting or anything, just this device. My question is since its still on 1.73 should I unlock bootloader via HTC Dev, and will this mean i can always run a custom recovery and ROMS going forward?
Example: if bootloader is unlocked, can I then update a device to the most current (2.2 i believe) and still be able to have a custom recovery therefore run the ROM of my choice and even revert back to stock at will?
My goal is to keep it flexible and not lock myself out of an option because of an update. One of the devices is for my neice so I want her running stock for now, but would unlock the bootloader just as a safety net and to futureproof the device if we run some JB roms for her, or CM10. Any help would be greatly appreciate.
Im coming from a Nexus so Im not used to looking for exploits to run a ROM, well not since the EVO days. Thanks a plenty!

Honestly I wouldn't ever run the update on the phone. No reason to risk it as you can download the stock roms (or CleanROM) from the developers section and just flash it normally. This would be the most flexible.
Having said that, maybe someone else can chime in and answer your questions initial questions. I don't really know the answer.

Your lucky use one of the one click root methods there's some on xDA or some that I can givenu a link too.... Than go on to unlocked boot loader ...honestly of u want her to be stock put her on clean rom.

So you're saying I should root first and not use HTC boot loader unlock tool? I'm still trying to search for the answer to my questions as well. What's the best root method? I honestly would like to have a custom recovery, unlocked boot loader, and running stock 4.0.4 or better just to try it out first. Then find a good Rom . Any suggestions?

I would unlock your boot loader. Flash teamwin recovery project, and then flash a STOCK ROOTED rom, whether it be sense or cleanrom. This will remove the ota feature so you don't accidentally update your hboot
Using the HTC boot loader unlock method is fine, if you don't mind your warranty being void. If not try the manual version. All of these tutorials are available in the android development section.
Once your boot loader is unlocked you are good to go. Just DO NOT RUU to 2.20 or you will not be able to flash kernels and radios.

So even with an unlocked boot loader if I ota to 2.2 I'm screwed? Got it. So any suggestion on the best stock ROM and then a Jelly Bean ROM? Do the one click root methods work the best?

I was able to one click mine, however some users report they cannot use the one click method, but manual works for them.
Yes, never ruu to 2.20, even with an unlocked boot loader it will screw you over. If you ruu to 2.20 without supercid then you are just Sol completely.
As for stock ROMs, go try out Team Venoms ViperXL. Make sure you download "HTC One XL" and not "HTC One X" they are 2 different phones and flashing anything made for the One X will brick your One XL.
When it comes to jellybean, I am on MIUI because I like the iOS aspect of it. I still am a fan of Cyanogenmod, since that was the first aftermarket firmware I have used. So I would recommend CM10 unless you want a little more customization, then go with AOKP. I have never tried paranoid android, but it is a combination of CM10 and tablet display modes.
The One XL is codenamed "Evita" and the One X is codenamed "endeavour"

Are these ROMs fully functioning? Camera is important for me. I thought that CM10 wasn't quite there yet but I'm definitely going to check some of these out. I don't have a computer here so I can't do anything yet. Its killing me! Thanks again for all the suggestions, Ill take all the help I can get!

Many of the sense ROMs are flawless.
The AOSP (Jellybean) ROMs are pretty stable, and camera does work on them.
CM10 is still in Nightly, but I think it'll be reaching a stable build soon.

With a huge amount of awesome mods and customization options, I do not consider ViperXL to be a "stock ROM". Sense based, yes.
If the OP wants to stay strictly stock, there are flashable, pre-rooted versions of the most of the stock AT&T firmware versions.
But I think your point is a good one, that some of the custom ROMs build off of stock, while adding some optimizations and useful features, while keeping the stability of a stock ROM.

The 2.20 hboot plugs the whole by which kernels and radios can be flashed via recovery. So flashing the kernel/boot.img requires flashing separately using adb every time you flash a ROM. Not sure about radios.
Really, there is no benefit to updating officially either by RUU or OTA. You gain nothing, and lose ability to flash kernel and radios via recovery.

As said before - root, unlock bl, flash recovery and flash a rom, be it stock rooted or custom.
Don't update to 2.20 OTA.

Quick question but maybe off topic. Is the screenshot to MMS problem fixed with custom ROMs? I noticed that if I send a screen shot via MMS its so small the recipient can't see it. Maybe a bug just on 1.73? Annoying none the less!

[Q] - S-off failed - need guidance

HI all,
I am sorry if this question may have been asked before but I have followed the instruction on [S-Off] Facepalm S-Off for HTC Devices One S, One XL, Droid DNA
but I still can not get the S-OFF.
I use the toolkit : [ROOT] HTC One X AT&T 2.20 Firmware - X-Factor root exploit
I believe my phone is rooted but I can not get the S-OFF. in the bootloader it said "Temppered" unlocked but the S-on
Can I please get some direction on what I did wrong?
Cheers
I want to flash either the telstra stock or the Clean rom I beleieve. I am not sure which one to try but I want the one with the closest to the stock but the optimised version of the stock.
Thanks
Arda

"Tampered' means you are rooted. That is a good thing.
What step of the S-off process are you stuck on? Any error messages?
Did you confirm you have SuperCID?

Cheers for the reply.
The steps which failed was when I had to confirm the restore. This is on the process getting the superCID.
I accepted the restore but on the screen on the phone the restore said "restore starting" and then few seconds later it said "restore end" as if restore does not get completed.

Ha, I called that one! The use of "cheers" had me thinking you were not an American. Its the dual core version of the One X/XL right?
X-factor only works for the AT&T version. X-factor is failing to change the CID because (I think) its looking for the AT&T CID (CWS_001) and not finding it.
I think you have to change the CID the "manual" way: http://forum.xda-developers.com/showthread.php?t=1671396
Instead of CWS_001, of course you will be looking for your carrier's ID (whatever that is).

so if I want to flash firmware (closest to stock), which tutorial should I follow?
any recommendation for :
1. ICS version which is very stable?
2. JB which is very stable?
I am using my phoen for internet browsing, skype, WhatsUp and also emailing most of the time.
Any recommendation is greatly appreciated

At this point pretty much every Rom is stable. I don't think there are any ics roms in active development anymore. If you like close to stock go look at the roms in the android development section. They are mostly all sense based and each brings its own tweaks to the table

Don't muck around with firmware... HBoot versions etc. don't matter much once you have s-off.
If you like sense roms, Cleanrom is great (very close to stock) or ViperXL (much more customisable). You'll find both these in the Android Development thread. For a more native Android experience I'm loving Liquid Smooth, available in Android Original Development.
Good luck!

I really need some help with HTC One XL

I bought this phone outright, and I don't like the Telstra network so I put an Optus SIM in. Which works just fine, however I now have an issue which may or may not be related. I have unlocked my bootloader, and have obtained root. I cannot get s-off however, tried all the methods in this forum. And when I try to install a new Rom, such as cm10 and all nightly versions, venom viper, and all other Roms I have tried I cannot get passed the start up logo (or I just get a pure black screen). Yes I have waited and waited for extended periods of time but it won't load. No I'm not new to rooted phones, and have followed all insructions properly. Pls help me, I really hate all the Telstra bloatware on my phone.

Only problem is I used that stupid one xl one click toolbox for my root. Which has completely stuffed me up.I should have done it the hard way like I did with my incredible s. I just got lazy. Don't suppose you know how to get s-off, without the one click fixes. Unfortunately they arnt working on this phone to acheive s-off

Not necessarily. It depends on your hboot version I believe.
I've never had to flash the boot image and I haven't done s-off.
@OP - did you need to s-off for any specific reason? You don't need to do this to flash a custom ROM. It's not required unless you want to reove the tampered text from the boot loader.

It makes life easier to have s-off. Besides I have issues with not having full access to something I have bought outright....lol

I s-off'd my HOXL because it makes it much safer from my own boneheaded mistakes. If I had done something silly like flashing the OTA RUU then I wouldn't be completely screwed.

rogers one X n00b help thread

Hi Guys!
Just wanted to introduce myself and ask a bunch of n00bish questions.
I recently acquired an HTC One X on Rogers for dirt cheap (basically $0) and this is my first Android phone having used an iPhone for the past few years. I'm not completely lost around ROMs having cut my teeth on windows mobile phones right here on xda-devs years ago but my iPhone took me away for a number of years.
I've gone through as much of the existing FAQs and help threads as I could but I have a few questions I couldn't find the answers for: Hopefully these are simple enough for the folks here!
1) My HOX out of the box is running FW version 1.73, Android 4.0.3. I see there's some bootloader unlocking issues with AT&T HOX's with FW 1.85 and 2.2 and above. Do these restrictions not apply to the Rogers HOX? Is there a point i should be worried about not having an unlockable bootloader?
2) My ultimate goal is to get a maintainable ROM where I can easily get OS updates without having to manually reload any custom settings or apps. Being an Android n00b, I consistently hear about Cyanogenmod ROMs. Can I jump from my current Stock ROM straight to Cyanogenmod 10.1 JB? or do I have to do something in between?
3) Are there other community ROMs that's better for the HOX than CM? I'm looking for a plain jane out of box experience. I really love how the iPhone works really really great out of the box without any huge amount of setting changes. And that's what I strived for with my old windows mobile device ROMs.
4) Yay or Nay on HTC Sense?
5) Yay or Nay on Staying on the Stock Rogers ROMs (I think the JB update is available now).
6) If I elect to do all the OTA updates, is there something I should avoid like a permanent locked bootloader version or something like that?
7) If I install all the OTA updates and eventually end up on the Rogers JB rom (I assume it's a bunch of incremental updates since auto updates shows I have update 1.93 which isn't the JB rom), can I revert back to the 4.0.3 rom?
I think that's it for now... Sorry for the long list. it definitely grew as I typed it!
Thanks a tonne! I know how great a resource xda-devs was and is. Can't wait to get into all of this again. !

Rogers does not lock down bootloader. You should be fine.
As for sense or aosp it just depends on preference.

apologies for my probing questions as I'm trying to flesh out the dependencies of everything...
Does the rogers HOX need to be s-off'd when flashing custom ROMs.
How do OTA updates work? Do they only apply to a certain kind of stock ROMs? Do custom ROMs have OTA updates?
thanks,

Depending on hboot yes s-off is preferred because it makes flashing easier. You will not have to flash boot image seperately. Some custom roms have ota built in so that you are notified of a new version. Once you start the unlock process it is wise to never take an ota update for stock Rom. Aosp such as Avatar and Sense based Viperxl both can be ota updated. There are more. It will usaully state these capabilities on the page.

When you say I shouldn't take an OTA update after unlocking the bootloader, why is that?
Let's say I unlock the bootloader, but keep the stock rogers ROM and OTA update it. These are just OS updates right? they shouldn't touch the bootloader or do they?
Also, if the Rogers Bootloader is not locked down, then do I even need to unlock it? or do you guys mean it's unlockABLE and still needs to be unlocked?
Does rooting also make a device not OTA'able?
Finally, how are the bootloaders tied to the FW version and to the OS version? Coming from an iPhone, there was the baseband/Radio FW and OS versions, and sometimes a specific hardware version, but that's it. what's the heirarchy for the bootloader and the FW, and the OS?
finally, if there's a good resource that answers a lot of these "android rom 101" questions, please send along a link. I know you guys are busy!
Thanks!

Thanks venomtester, I was just on those pages when I went to check for your reply.. =)
For a general question to the Rogers HOX folks...
just wanted to confirm the following workflow:
1) unlock my rogers HOX with htcdev unlock process
2) get root by running superboot r2
2) run facepalm to s-off my HOX
4) pick a ROM and flash!
That sound about right? I'm not missing anything obvious? I'm not entirely sure if the tools like superboot r2 and facepalm have been superceded by other tools. Especially with all the AT&T specific processes...
This certainly is a few more steps than I'm used to from my Windows Mobile days... =)

Step 2 should be flash TWRP 2.3.x.x no need for superboot r2?... not sure what that is.
And you'll need to flash a rooted rom before S-OFF or let TWRP root your rom if your hboot is under 2.14

Hboot 1.09

Can someone tell me the benifits of hboot 1.09... I am currently on 1.14 with s-on
Sent from my HTC One XL using xda app-developers app

With hboot 1.09 and S-on, boot.img is flashed automatically from recovery anytime you flash a ROM (does not need to be flashed using fastboot). Also, radios can be flashed from recovery.
Both are possible now (with any hboot) if you are s-off. So I'd recommend s-off.
Also, this should have been posted to the Q&A forum section. So I've reported to the mods to move it.

Be careful what you install from cm site. There are roms that are for the international one x and if you flash those you will brick your device. Stay on this forum and scan original android development thread, that's where you will find the correct cm roms..

Thanks, also, what are the benefits of S-off??

You can find the answer to that if you just read. Buuuuut, it removes security checks basically, so you can really flash anything to your device.
This means you can run any RUU (for this device) without having to relock the bootloader etc, it also means that people on hboot 2.14 are able to flash kernels in recovery instead of flashing boot.img through fastboot. Plus you can downgrade touchscreen firmware, remove red text from splash screen, and edit "tampered" flags within hboot I believe.
This also comes with risks though. Because there are no security checks, it's easier to brick if you flash something that is not intended for our device (ROM / RUU).

If you want to flash aosp ROMs you need to. If you want to only use Sense ROMs you don't need to. I suggest doing just so you have that freedom in future.

All true. Plus, there is some type of bug where if your phone is SuperCID and S-on, you can brick if you try to install official the JB OTA or RUU. S-off removed this particular risk factor.

If you install the JB OTA or RUU, it will upgrade the touch panel firmware, which is not compatible with AOSP ROMs. The touch panel firmware is independent of hboot, ROM or radio. So only a JB RUU or OTA will give you the updated touch panel firmware.
So if you for some reason end up running the RUU or OTA, and end up with the newer touch panel firmware, and want to run AOSP ROMs, you need to downgrade the touch panel firmware (S-off required).
