[Q] Boot loader

Hi. I have a Htc one x that was locked to Three. I got unlock code which worked now on Orange ( EE). I tried to unlock bootloader with no success. Do i have to do something because the phone was locked to Three. Please help as i want to root phone.
Gary.

In what way did it not work ? Assume you followed the HTCdev method.

I don't know if it resets the phone locked to 3 again when you unlock the bootloader, because unlocking the bootloader will reset the phone back to stock and i can't tell you if your carrier unlock code will still be active after this.
But what did you try to unlock the bootloader anyway ?

Thanks for the quick reply. I used the HTC Development method.Is there a way to root without the dev bit.

No, unlocking the bootloader must be done with the htcdev site.....did you get the unlock code.bin file ?

Mr hofs is right mate use htcdev site, plenty of guides knocking around on xda, I was locked to three but followed all the steps unlocked bootloader rooted, changed hboot and flashed a new Rom, daunting at first but so worth it you will see the difference.....good luck!

I would learn adb/fasrboot....much easier to get out of trouble !
Example :
You use a toolkit to unlock and flash a custom recovery, for instance TWRP. Then you make your nandroid backup and running custom roms.....all no problem then you need to return to stock and need to flash the boot.emmc.win (the kernel/boot.img) but the toolkits only supports boot.img file .......
Get the problem there ?

Thats true buddy, I admittedly had to use fastboot when returning to stock for an OTA update a while back (it didn't like cwm) so returned to stock with stock recovery and then later flashed another rom etc....I stand corrected - IF u need to return to stock!

I get ya ... no worries

I used the toolkit originally but learnt commands now. You then understand what your actually doing to your phone and are less likely to brick it or at least have a better chance to fix it if it does go Pete tong.

Is their Return to stock with s off tutorial yet?

Hello I just bought htc one m8 I want to root bad but I just want to make sure is their a way to go back to stock with s off yet?

No RUU is available yet. There are stock kernel files and you can make a backup in recovery of stock rom. But, if you convert to Google play edition there's no way to get back right now.

Do you mean that if I install gpe Rom,I won't be able to flash stock based Rom?

Correct, but only for now. Just waiting for the RUU to be released.

If you unlock with HTC Dev, the bootloader says unlocked or relocked (if you relock it).
To get locked again you need S-OFF.
However, I've seen S-OFF is (almost?) achieved, but no tutorial about restoring the lock flag.

There is some misinformation going on in here. You can flash a GPe ROM, and still be able to flash back to sense. However, if you flash the GPe RUU, then you are stuck until we get a sense RUU. Also, s-off has already been achieved, check the original development thread.

You can install a GPE Rom and then flash back to a Sense Rom no problem. What I was saying is if you do the full GPE conversion by flashing the GPE RUU, there's no way to get back to Sense until an RUU is available.

I know we can S-OFF, but after that, how do we set the device back to Locked instead of Unlocked or Relocked?

IF you have an unbranded EU handset there is a way to get back to 100% stock with a bit of imagination...
1. Flash the stock odexed 1.54.401.5 ROM @mike1986. provided HERE
2. Flash the stock 1.54.401.5 recovery provided HERE
3. Relock the bootloader (or, if S-OFF, reset the tampered flag and lock it again)
You could also look into flashing the 1.54.401.5 firmware package to be ultra-sure you have everything done but if you were already on 1.54.401.5 before going custom it's not really required
That should do it...

confused a bit?
Dont want sound like a newbie but so if I unlock the bootloader and turn s off then its rooted and I can flash any recovery I just want to clear things real quick if I want to restore it like from the day I got it its possible if I follow your directions? I got the atnt version to I know I sound like super newbie but Its just a little more complicated to do this on htc one then it was when I had the s4 no doubt tho htc one m8 is amazing!!!

But.. how?
I mean, I know how to relock (there's an HTC official method), but if i'm S-OFF, how can i lock?

There's a thread on removing tampered and showing locked in android Dev section. I believe it just flashes a modified hboot file. Then you just need to s-on:
Fastboot oem writesecureflag 3
Then lock your bootloader which you know how to do.
There have been issues with running an RUU after messing with your bootloader while S-on with HTC Phones in the past so to minimize possible bricking be sure to see your CID back to its original if you changed it and possibly even leaving the phone S-Off if you plan to continue using it after returning to stock.

No, you can lock it first as doing the normal will show 'relocked'. When S-OFF, you can set it back to 'locked' and then S-ON again (if you really want to). Guides are in General on how to do this

g2's RUU on DZ

Hi. Is it possible to install official T-mobile G2 RUU software on HTC Desire Z?

So long as radio secure flags are removed (s-off) then yes, but I can't think of a great reason to do so
Sent from my Nexus 4 using XDA Premium 4 mobile app

I love AOSP. So I can download RUU eg. from here and simply run the installer?

Yes but that would leave with a shipped bootloader, stock recovery and a non rooted ROM. Maybe a worse radio too. Why not just flash a stock rooted ROM?

I can simply root it again by eg UnlockRoot program. but I want to have clear software, I dont like custom roms. And also I cant find newest 2.16.531.6 ziped rom. I prefer to install this RUU.
...but first I have to fix my phone. I dont know why, but I cant run anu RUU installer (even this for DZ). when I click "update" button, it is waiting for bootloader, and after this there is a comunicat that phone is unpluged. I wonder I have to do this with ADB
But thanks for your answer this is what I wanted to know

Sort of, if using some unlock program for root I have to imagine your not s-off and if you are its fake s-off which if you were to run the RUU you may brick your device. The only method you should use to root your phone is exploit via gfree.
As for custom ROMs, that's your choice but I will say there are ROMs that are more aosp than stock T-Mobile as all the g2 stock isn't pure aosp. Buy of course do as you will.
As for your RUU issues, it won't have anything to do with adb as they are to be flashed through fastboot, but again be careful as what you want to do is possible but if you don't meet the prerequisites you will have a brick
Sent from my Nexus 4 using XDA Premium 4 mobile app

Ok, you are right. I'll flash some another aosp.
But now, this RUU issue.
So, from the beginning:
I changed the hboot to g2 one with this PC10IMG. Just flash by bootloader. Then I flashed the PC10IMG_Vision_TMOUS_2.15.531.3_Radio_12.52.60.25U_26.08.04.30_M3.zip. also by bootloader. Then found out that I cannot use RUUs installer because the phone dont wont to reebot into bootloader. So i change hboot to dz one with this PC10IMG. Now my hboot version is 0.84.2000 (PC1011000).
I installed some custom rom (virtuous sense 2.0.0).
I am running RUU software (RUU_Vision_Gingerbread_S_HTC_WWE_2.42.405.3_Radio_12.56.60.25_26.10.04.03_M_release_224299_signed.exe).
returning to the bootloader - is ok, phone is reebooting. But next is 'waiting for bootloader' and the Error, that the phone is unplugged.
On the phone screen for a while was the Black screen with Gray HTC logo, but for the moment there is white screen (looks like bootloader) with hboot version, Radio version, etc,
and at the end is: RUU
I hope you understand me.
What shoud I do? mayby the hboot version is incorect?
edit
I also cannot install 1.34.405.5_PC10IMG.zip by bootloader now. The files are loading, and then.. is nothing. There is no quastion for Update( vol up) or No (vol down)
edit2
Uff, the problem is solved. I hadn't installed bootloader drivers and radio was very old, so I had to update it. Thanks for your help, demkantor

No problem, I would advice to look through this thread a bit as well

[Q] unlock bootloader - root - flash custom rom

Hello,
Will unlocking my bootloader break the guarantee ?
I did a lot of flashing on the m7 , but have completely forgotten adb commands.
Can someone help me?
At first I will need to make a backup so I can go back if I screw things up how ?
And what was the url for htc bootloader unlock ? Htcdev something I guess.
Can someone who has the time help me a little bit.
regards MrCaligula / Norway

1: yes it may break warranty
2: Google for adb/fastboot minimal and check the stickied guides that's so easy to find
3: Google for HTC dev and it will be on top

Bootloader now unlocked
What is next ? Do I need S-off ?

To simply flash a custom rom s-off is not mandatory

If you on the other hand want to flash a custom ROM build for a higher firmware than the one you're running s-off is needed to flash the firmware corresponding to the custom ROM you like.

Thanks for your help I flashed the Ehndroix rom now . Seems good so far
Still on S-off I came from Stock 4.4.3

[Q] Back To Stock

I have an AT&T M8 with 4.4.3
Its unlocked and rooted, firewater was unsuccessful with this error....****** device patched by HTC, you are out of luck *********.
Is there any way to return to stock without S-Off?? If so could someone please point me in the right direction?
I'm a newbie with htc and very aggravated with this phone.

Can you provide me with the link that says you need to be S-OFF to get your phone back to stock, where you clearly didn't have to be S-OFF in order to take it away from stock in the first place?
I'm asking this because you are one of many that I've seen recently that comes on here asking the same question, can I go back to stock while I'm still S-ON ? "Should I be S-OFF in order to restore a nandroid backup?" etc...I would really like to know where you guys get this information from?
The only thing that you'll need S-OFF for(when going back to stock) is to fix the tampered flag in the bootloader and to have it show "locked" instead of "relocked" when or if you locked the bootloader.
That being said, going back to stock from where? Did you flash custom ROMs? Or are you only rooted and unlocked?

My phone is stock, but unlocked with root, my main goal is to reload the original recovery, relock and unroot.
I was watching a video on how to use RUU and according to the instructions you had to be S-Off.

You need S-Off only when you want to remove TAMPERED and RELOCKED flags.
Other than that, you don't need S-OFF
You have AT&T device, AT&T forum is where you'll find more info.
Try this one : http://forum.xda-developers.com/att...-2-23-502-3-bootable-ruu-pc-required-t2860486
Important note :
S-On - you need to relock bootloader first before running it. So read and read the instructions
and there are many more guides on AT&T forum

You could use the AT&T RUU that is available on the AT&T forum.
At&t 2.23.502.3 - 4.4.3 Bootable RUU - No PC required - Mac friendly
Like the OP there said, if you are S-ON you should lock the bootloader first before using the RUU. I think that should take care of most of the other issues you have, like unrooting etc. Make a backup of any personal stuff you have on phone.
Or
Download unsupersu, flash it in custom recovery to unroot device. If you use SuperSU you can also go into settings for SuperSU and use Full Unroot. Reboot phone, can then uninstall SuperSU. Should be unrooted.
Flash back stock recovery for your device.
Relock bootloader - fastboot oem lock

Will this also restore the factory recovery instead of twrp that is on the phone now?

That's also in that very same thread we linked you to!
Post number 7
Post number 15
But I take it you didn't read at least the first 2 pages...
It'll take you back to stock completely, like the OP said in Post 15.
Just remember to relock your bootloader seeing as you're S-ON.

Thanks for your patience and help,
it worked flawlessly.
