[Q] Unlocked bootloader, 4G/LTE no longer works

Hi,
I tried to use the one-click bootloader unlock at http://forum.xda-developers.com/showthread.php?t=1734558 several times, but it did not work with my phone (Telstra HTC One XL) due to an invalid token, so I ended up going through HTCDev.
Problem is, although the bootloader is now unlocked, I now have the same problem as this person: http://forum.xda-developers.com/showpost.php?p=28045161&postcount=42.
Is there any way to fix this or am I screwed? The phone works fine, except I no longer have 4G/LTE. I have already tried to restore my original partitions that I backed up, but it doesn't re-enable 4G.

Sounds like a bug HTC needs to know about.

Why not try rooting then unlocking directly at HTCDev.com without using this script?

I've already done this.

Try the RUU.

Reflashed RUU, same problem. I've convinced the telco to send it in to HTC for a repair... doubt they'll do anything as the bootloader clearly says "Relocked" and I logged into HTCDev.

you check your imei # in the software and make sure it matches what it should be (it's physically etched into your sim tray)?

I have an unlocked bootloader and 4g/lte is working fine with cleanrom 4.1 and the 1.88 radio here in nyc area. Got 45/11 in flushing queens on lte.

Maybe someone can post their backup (original) partition files??

(Q)S3 Unlock Bootloader

If i can unlock the S3 while rooted can i unlock it on a stock factory not rooted S3? Is there any way we can unlock it without being rooted?

I don't think so. You need the image that ez-unlock installs when you unlock for the 1st time. plus ez-unlock backs up the stock image so you can relock and than return back to stock with odin.

Ahhh ... i would have thought that we could unlock without being rooted using the ez unlock.... thanks for an answer

Need help
I'm abroad now, and need to unlock my Verizon S3.
After rooted by RootDebugfs then using EZ-Unlock, it still gives me " Non Verizon sim" for the Vodafone sim.
I've tried several times to to uninstall then reinstall the EZ-unlock for both versions 1.4 & 1.2 but the problem still exist.
At last I uninstalled both Ez-unlock and Super Su.
hope to get rescue.

EZ-Unlock unlocks the boot loader, not the SIM or whatever is involved in unlocking the phone. Same term, but not referring to the same thing. It doesn't carrier unlock your phone. I'd offer some assistance with that, but I'm not too familiar with it.
p.s.
For future reference, you should be sure of what an app does before using it.

still need help

Can some one help in detailed steps what to do?

[Q] Can i update my firmware to 2.20

Hi Guys
Sorry for asking the same old question again..
I just got my AT&t HTC One x from US shipped over to India by my cousin.
It is locked to AT&t and i am unable to use a local network sim in it
I know i need to root it and turn S-off in order to unlock it.
The phone is on Firmware 1.85? and i have tried the ways mentioned in xda to root it but i guess when i click "Check for updates" it doesn't work.
So my question is
Can i manually by connecting the phone to Computer,update firmware to 2.20 so that i can root it that way?
And is it possible to unlock the BOOTLOADER w/out rooting so that phone gets unlocked to other carriers?
please help me out guys i have tried everything to make it work.. thank you

Unlocking the bootloader/rooting/dancing in circles WILL NOT sim unlock the phone.
You will need to use an online sim unlocking service (usually about 20 bucks) to get the unlock code

Currently, S-Off has not been achieved for this phone. And as already mentioned, bootloader unlock will not get you SIM unlock, and no free hack/mod method currently exists. You either need to use a paid unlock service, or if your cousin is currently an AT&T account holder, he can ask AT&T for the SIM unlock code (he will need the IMEI number of the phone, and maybe other info).
If you want root and unlocked bootloader for other reasons (flashing custom ROMs and other mods) there is no reason to upgrade to 2.20. Root method exists for 1.85. You need to root, SuperCID, then unlock the bootloader. Then you can install a custom recovery and flash custom ROMs.
Upgrading to 2.20 is not recommended. The 2.20 RUU will upgrade your hboot, which plugs the holes by which kernels and radios can be flashed from recovery. You will have to flash the boot.img separately every time your flash a ROM. No benefit to updating to 2.20, and actually lose ability to do some things.
If you still want root and bootloader unlock, refer to my index for links to root methods, etc.: http://forum.xda-developers.com/showthread.php?t=1671237
And no, bootloader unlock is not possible without root (temp root in case of 2.20) on the AT&T One X.

Thank you for a detailed answer. The reason i though it would unlock the sim was cause i had used other htc phones earlier and when you root them the S-off was achieved so thats why.. anyhow.. thank you for enlightening my dumb bum.

You're not dumb. Just ignorant. Now you have been enlightened. You still have a great phone, you just might have to pay a little bit so you can unlock and use it

The word "ignorant" has always sounded like a pejorative word to me. But I had to look up the definition, figuring maybe I don't really know the literal meaning of the word. Which turned out to be the case. One of the definitions of ignorant is "Lacking knowledge, information, or awareness about something in particular" which seems to exactly fit this situation. I guess I gave myself the English lesson for the day!
Every phone is different, and HTC in particular is always changing around their security measures. So the OP is not dumb in any way, but was just missing some particular pieces of information.

[Q] Seriously need help with unlocked ATT One X

Alright guys, I am posting out of desperation.
I am no pro when it comes to rooting/unlocking/ROMming Android phones but I have read myself to death and I am not getting anywhere. I am almost willing to send this phone to someone who knows what they are doing. I really don't feel like buying another phone. In hindsight, I should've made sure I was getting a true unbranded HOX.
I bought an unlocked, AT&T One X from Amazon while I was in Afghanistan. Received the phone via APO, put in my Roshan SIM card, and was working fine. I traveled extensively in the past few months, all over the Middle East and South Asia, phone was working fine, I just picked up a local sim card and off I went.
Well then I went back to the US for the first time with this phone. Put in my TMobile SIM, and was working fine as well. Well now I left the country again, and now I can't pick up any networks at all. I have changed the radio via the USSD to GSM, WCDMA, everything, but can't pick up any networks. Keep in mind I also still have my SIM card that I bought when I was here. I insert the card, it says preparing sim card, etc, but won't find any networks.
How do I know if the phone is still SIM unlocked? Woulnd't it prompt me for an unlock code when I insterted the foreign SIM again? Do I need to root? Does my bootloader need to be unlocked to use any SIM?
What I was figuring I would try to do was flash a different ROM so I don't have to worry about this being an AT&T phone anymore. When I boot into the bootloader, it says LOCKED at the top with S-ON. There has never been an update done to the phone since I got it.
Things i've tried:
Any root for 1.85 ( I have tried every root for 1.85 you can search for on here)
RUU to update to 2.2 (says main battery power low, but it isn't)
Factory Reset
I really don't care so much to get a new ROM, I just want my phone to work. Here is what I get in the info page on the phone:
The bootloader says HBOOT 1.09 is installed
Kernel Version:
3.0.8-01155-gca24d1e
[email protected] #1
SMP PREEMPT
Build Number
1.85.502.3_R2 CL63811 release-keys
Sense 4.0
Android 4.0.3
Software Number
1.85.502.3 710RD
If you need any more info let me know but I am dying here

Sim unlock and bootloader unlock are two different things. I don't think either has anything to do with the other.
Assuming you bought this from a legit seller on Amazon, factory unlocked is factory unlocked. I've never heard of a phone getting sim locked from putting in a sim card. If you didn't get a "input unlock code" the first time, your phone isn't sim locked and is not locked down to AT&T.
Before you can root, though, you have to unlock the bootloader. That's why your root attempts keep failing. You want to stay on 1.85, trust me--later firmware is more locked down.
Are you sure there's nothing wrong with the other sim card you got? Have you tried a new one?

Really? The bootloader has to be unlocked before you can root? I definitely thought it was the other way around. I guess that would explain it, then..
What I actually ended up doing was repeatably trying the RUU, and finally got it to take the 2.2FW upgrade. As soon as that happened, I was pulling down 4G like nobodies business. Though, now that i've read your post, I kind of wish I would've stuck with trying to get a new ROM on it, instead of upgrading. I really have no idea why a FW upgrade made the radio start working like magic, or what would casue that at all.

Progress is swift. I rooted using the 2.2 xfactor exploit and then unlocked the bootloader with the spoofed CID, now as soon as I figure it out I will install CleanROM 5.1..Hope I don't brick it!

As long as you stay in this forum, these phones are tough to brick. The only way to do it is to flash roms for the international (Tegra 3) version.
Note that on 2.20., you have to flash the boot.img in fastboot when you flash a rom.

Youll never brick your phone as long as you have access to the bootloader or recovery lol

If he wants cleanrom he won't have to be confused with fastboot. Just download rom and flash that sucker

Do NOT RUU to 2.20! (never mind too late).
Looks like you figured things out.

[Q] Carrier (AT&T) Unlock Code Unsuccessful

I received an unlock code from AT&T for my One XL. The unlock code comes up as unsuccessful. I followed the unlock instructions exactly. And I've called back and verified that AT&T has the correct IMEI and double checked the unlock code. I've never had an issue unlocking a phone before.
I contacted HTC. They tell me to contact AT&T, as "they're the ones who have the unlock codes." AT&T tells me to contact HTC.
Would running CM 10 have any effect on my attempt to enter the carrier unlock?

Yes, SIM unlock codes only work on Sense ROMs, for some reason. Switch to a Sense ROM, and you should be able to unlock just fine. Then you can go back to CM10.

Do I have to go back to a stock ROM? Or just any Sense-based ROM from "HTC One X Android Development."
Would you know of a guide? I can't even recall which stock Rom I was running prior to unlocking the bootloader and going to CM10.

You don't even have a backup? Any sense rom is fine. They all have instructions that are easy for anyone to follow.

Restored a backup from 9/2. I forgot I even had it, as I didn't intend to go back to it. Unlock worked. Thanks all!

yupp sense ROM is the key
