Question: How to Lock and S-On back to factory settings? - Verizon HTC One (M8)

I have to do a 14 day exchange on my phone. Bought it at Best Buy. I have a few dead pixels amongst other things. I'm very familiar with ADB, bootloader, custom recovery, and OS. Right now, my M8 is unlocked, s-off , and rooted. It's running a custom rooted RUU Rom. Before I attempt it, what would be the best way to get my phone back to its original state? Does Best Buy even care? Does my account get linked to HTC when it is sent back and I'm charged $600 for it being s-off? If I understand it correctly, and I'm asking if this is right, I would want to find and download and flash the original RUU through ADB, find and type in a line of code to Lock bootloader, and find and type in a line of code to s-on, right? Or does best buy not even check or care?

He is quite knowledgeable and gives a good discussion of what steps are appropriate/reasonable/safe to take in these situations.

Ok, I'll check out it. I also found this to install rooted original firmware back onto the HTC M8, it might help with my situation, or it might help with others http://forum.xda-developers.com/showthread.php?t=2727831

[Q] Need to restore to stock in order to RMA

Hi all, any help would be much appreciated.
I'm from Canada and bought the HTC One S from Expansys a few days ago. It was compatible with my Rogers network, however, I JUST switched over to Bell and unfortunately, this version of the phone, while unlocked, is not compatible with Bell's network. As a result, Expansys has agreed to let me return the phone, however, during the short time that I was using it, I had rooted and installed a custom rom (WITHOUT backing up the stock; boneheaded move, I know). The phone seems to be the European version from France, so I was thinking of restoring to this: http://forum.xda-developers.com/showthread.php?t=1543588 however, I remember reading an article on Rootzwiki about how our phones are marked once we unlock the bootloader. Is there a way to remedy this? I'm afraid Expansys will reject my return if they notice that I've "tampered" with it and would like to return it fully to stock, unrooted, completely original everything.
Again, if anyone can direct me how to proceed, I would be so grateful. I have two weeks to send my phone back.
Thanks guys!
Thanks
I would love to know the answer to this as well. Kinda in the same boat...My main concern is removing CWM..Anyone have any info on this?

Based on all my readings thus far, it seems removing the "tampered" message is not possible yet.
In order to remove CWM and revert back to stock, I recommend hasoon2000's All-In-One Toolkit: http://forum.xda-developers.com/showthread.php?t=1604677
There is an option to flash the stock recovery.

You can just do the following:
Remove root - can be easily done via superSU app from the settings menu, where is mentiones full unroot
Flash stock recovery
Relock bootloader.
After that if you want, just find the correct RUU file for your phone it it will flash it. The word tempered will go away, but it will just say "relocked"
I don't think that expansys will access the bootloader to check....Most employees are not tech savvy...As long as they power the phone on, without problems....you should be fine.
you will always see the brand relocked. untill we have al full s-off it wil be like this always.
just flash the correct ruu it came with,
if the phone works normal they wont have a reason to look at the bootloader.

How to remove CM 10.1 and unroot for warranty?

Hey guys, I need to bring my phone in to AT&T for warranty on a defective screen but my phone is currently rooted with CM 10.1. The online AT&T representative said that since this is a hardware defect, the software won't make a difference but I don't want to take any chances.
Is there a guide on how to unroot and go back to stock software so I can still use my warranty?
Thanks!
All help is greatly appreciated!

Attain S-OFF if you haven't already. There's a sticky in the original android development section.
Then run the RUU with your phone plugged in. If you want to keep root/unlocked, I don't suggest relocking the bootloader because if you do and they happen to update you to 3.18, you'll be SOL.
Good luck.

Well they are just replacing my phone so I just want to do as little as possible so they honor my warranty.
Then just run the RUU, I'm sure that'll be enough. If you're extra paranoid, after running the RUU you can fatsboot oem writecid CWS__001
And then you can spoof your bootloader to say S-ON and LOCKED instead of S-OFF and unlocked or relocked. If you click the resource compilation link in my signature, I believe there's a link in the MODs portion of the OP.
Chances are they will replace it with a phone with 3.18. No root for that yet. You may get lucky though.
Good luck.

AT&T One X Back to Stock

Couldn't seem to find my exact answer. I am getting ready to sell my AT&T One X as I just picked up the S4. I currently have the bootloader unlocked and rooted. I was wondering what is the best way to go back to stock for selling purposes.

This should've been posted in Q&A but I'll help you out anyways since I'm in a good mood . First you need to s-off. Then, run an RUU (whichever one you want). After that, reboot into bootloader. Connect it to your PC and "fastboot oem lock". From there you should be good. If you want to make it appear as if you have s-on you can locate that thread, you can, but s-off shouldn't void any warranties, and since you're selling it anyways, there shouldn't be a problem.

[Q] "New" phone from ebay (villec2) that will not update. Unlocked/Rooted?

Hi
This is my first post here, and I'm hoping somebody could help me with some questions I have.
I have recently bought a "new" HTC one s on ebay, which may seem to have been a bad idea. I have later discovered that it is not a z520e (snapdragon s4), but the cheaper z560e (snapdragon s3) version, or villec2 running android 4.0.3.
Anyway, I have tried to upgrade the phone to the latest android version, using the built in phone function. However, this did not work and I got an error message telling: "We have determined that your phone may be running modified version of its system software...". In other words, I have the feeling that the phone is tampered with. Maybe the seller have unlocked in a way that makes it impossible to upgrade. Is there anything I can do to check this? And is there anything i can do to upgrade to android 4.1.1. ? I have tried a factory restore (phone function) with no luck. Or is the update only available to Asia?
Any information is very appreciated. I would like to know what the seller have done with this phone, information which I can use against the seller. Thanks!

When the phone is off, press and hold volume down then press power button (don't hold).
This will let you enter bootloader.
Top of the screen if it says unlocked, that is why you cannot update.
I'm guessing you do not know about fastboot commands/ adb commands and are not interested in learning to root and load custom ROMs to your phone.
But if it is unlocked and you want to relock it you just need to type in a command prompt: fastboot oem lock
that is assuming that the stock recovery hasn't been changed. (which isn't hard to flash)
In this guide you would want to download that fastboot.rar file
http://forum.xda-developers.com/showthread.php?t=2175411
As this is a question, I've moved this thread to the Q&A, Help & Troubleshooting section.
In future, please remember to ask any questions in this section rather than in General.

First of all, sorry for the posting in the wrong category.
You have right that i have no experience rooting android phones. However, i managed to jailbrake an iPhone 1st gen in the old days.. Anyway, my main concern is to try to find out what this phone is running, and if I should send it back or not. I paid 260 usd, so I would like the phone to be ok/not too much tampered version.
I got into fastboot / Hboot, and it says unlocked. What does unlocked actually means? I also got some red text when i started the phone afterwords telling that it was some non officially software that were not allowed to be distributet (went a bit fast).
I guess this is the reason why I cant update. Is there some more information I can take out of this Hboot? (I tried to find a hboot guide.) Any ideas why the seller sold me an unlocked phone? And is there something i should make sure of before I decide to keep the phone? I might send it back if there is some tampered things here.
Thanks again for you feedback!

HTC allows to unlock the bootloader from their website. You are sent an unlock bin code. Unlocked means you can root the phone, you can put on a custom recovery to make backups of your phone and put custom ROMs on it.
If yours said unlocked, and right below that if it did not say tampered, then i believe you still have the stock recovery.
you just need to download fastboot files to your pc then you can lock your bootloader.
you go back into bootloader and plug your phone into computer (phone will change from fastboot to fastboot usb)
from your fastboot folder you hold down shift and right click the mouse, choose the option to open a command prompt.
from there you just type
fastboot oem lock

Thanks for the reply!
Yes, i cannot see any "tampered" below the *** unlcoked *** line in HBOOT.
I tried the recovery in the HBOOT but got a red triangle. I guess i need to to this from an PC (I have macbook at home, or do I need the Andorid SDK on my computer maye..), and download the right android image etc. I also guess the factory reset will not help me either (probably the same function I can choose from the settings menu in android.).
Now my question is if I should try to change it to a z520e. I guess i will get some more battery life with the snapdragon s4. But not sure how much, and if its worth the hassles with return shipping etc.
Anyways, thank you very much for the information!

MY HTC ONE X AT&T has this screen and wont start up

please help me. i dont know what to do with this cell... anyhow i managed to get it into this screen...
it would keep restarting after displaying htc quietly brilliant.
i have no idea what was done to this cell as i got it lying around in my closet.
What do you mean you got it lying around in my closet? You don't know what you did to it in the past?

Well I think the first thing you should do is talk to your cousin and find out exactly what he did to the device, then you can report back here.

is there any other way through which we can come to know what can be done??? such as an odin thing which i used to do in my samsung note 1 or 3???

To know what needs to be done I need to know the history of the device. Odin is Samsung only, there is no HTC equivalent. Who got the phone to this point, you or your cousin? You need to find out what he's done.
Sent from my Evita
Well, one problem is that the screen is cracked.
Seriously though, the phone for some reason or other cannot load into the OS, and is stuck in bootloader. Other than that, not much else can be determined if you don't know the history of what was done.

Nope. You need to know the history of the device. There is an HTC-specific recovery utility. But running it on a device with unknown history can brick the phone permanently. Particularly since the device is definitely tampered (as shown on the first line of the screen).
Also, the phone's IMEI is personal information, and should not be posted on the internet. You should edit the photo to hide the IMEI.
Unlock your bootloader. Sometimes if you have custom installed or fragments of a custom ROM on the device it will boot directly into your bootloader. After unlocking your bootloader you can install a recovery image and sideload a ROM.
yes i asked my brother and he is saying he doesnt remember what he had done to it... if anyone can show me a way to do something ill try it... or else should i take it to some shop to get it fixed.... which would cost me... but first i wanted to get my hands over d expert advise of u all
Return the phone to stock and never let your brother touch any electronic device of yours again.

This phone is in a dangerous state.. Running the RUU in this state could brick the phone (make it permanantly unusable without a jtag). Though typically that is how one would return a phone to stock.. to be honest, the safest thing to do would be to unlock the bootloader, flash a rom, S-OFF and then return it to stock. If these seem like foreign terms to you, you have a lot of reading to do. Your phone is in a tough spot right now ESPECIALLY not knowing the history regarding what was done. You would need the bootloader unlock token to reunlock that phone if you don't have it, there's very little chance of safely returning that phone to stock.

Brother or cousin, or both? It seems you don't even know who has been messing with your phone. And the person(s) messing with it don't have a clue what they are doing. So its no wonder the phone is in the state it is.
Agree with above that RUU is risky. Better to s-off the phone first.
Thank u all for the prompt replies, I have played with Samsung but not with HTC. But I can try to unlock the bootloader n turn d s-off. Can I get an step guide for HTC. The thing was I have many cellphone that I buy and use it very rarely. Majority I use is my note 3.

There are detailed instructions available at htcdev for unlocking your bootloader. Once you've done that you need to flash a custom recovery, then you can flash root, then you can get s-off. Check my How-To Guide For Beginners thread, the link is in my signature.

Every device manufaccturer/model has different root methods. If you want to root the phone, you have to put the time in to learn the correct process. There is no shortcut. You won't find a step-by-step guide for the entire process, because of the different carrier version and firmware updates (root method, etc. differs for each). But all the resources you need are sticky at the top of either this Q&A forum section, or General section.
hi i tried to get to unlock the bootloader from the HTCDEV site. first of all the HTC ONE X wasnt on the list so i selected other supported devices
then followed the steps and got the following error
Error Code: 160.
Error Reason: MID Not Allowed.
now what does this mean??
That means you have the original CID still, which means you should be able to run the 3.18 RUU without any problems. Check your CID by issuing this fastboot command:
Code:
fastboot oem readcid
Sent from my Evita
yes i had issued this command after finding it in one of the websites and this was the result which i got
cid: CWS__001
or cid: c??__001
i forgot the exact two letter after C. i think it was CWS
You have the original at&t CID. That means you can run the 3.18 RUU without having to unlock the bootloader and get s-off first.
