[Q] How do you relock bootloader? - Shield Q&A

Hi guys wanting to update my rooted nvidia shield to version 82, i used the Ramshield v1.1 method to return to stock recovery and rom, however the bootloader still states that it is unlocked.
Now updates all work fine and there are no problems however its just personally bugging me how i change this back to locked.
I've googled, looked all over xda and other forums (Not in any great detail so no shouting at me if I've missed it )
Any help on the matter is appreciated.

Fastboot oem lock if you have the proper stuff installed or you can use my shield setup if you want. However it serves absolutely no purpose, it does not reset the warranty flag.

[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.

Before Unlocking, What Should I Know?

I just received my TF300 and ASUS is asking me to update.
I'm currently running 2.6.39.4. Can you hack the lastest update?
I want to install CM. Can't wait.
And is worth hacking? Asus' UI replacement doesn't seem as terrible as my last device, a Droid 2.
(And since my phone broke and the replacement has a locked bootloader, I'm going to buy an S3 since MotorBlur is ****ing horrifying).

Can you root without unlocked bootloader?
Yes. I rooted with an outdated root method, so i'm not sure which method you need to use with the software you currently have. The info is there, you just have to sort through it.

This method appears to work with any firmware. I rooted from 9.4.3.29 with no problems.
2.6.39.4 is the kernel ID, not the firmware

How do i check xoom's bootloader status?

how can i check my xoom's bootloader status w/o actually wiping it? i only want to check its status but not actually change anything at this point. i have a canadian xoom and originally unlocked it to get the US rom and not be left behind . i never rooted it cuz i had no need to at the time, but i cant recall if i relocked the bootloader as i had no plans to do anything more than get google's updates; and have been receiving them as expected. while waiting for jelly bean, i've read that it wont work with my bootloader unlocked. thought maybe that was my problem and what was causing the delay. before i could do anything further, i got the notification and jumped in blind and updated. everything went smooth, but now i really have no idea if my bootloader is currently locked or not. how can i simply check/view this?
i thought about checking fasboot oem unlock and hoping it would tell me something, but what i dont know is 'is the warning screen any different if im trying to unlock an already unlocked unit' or will it show the same warnings and just unlock again?
-thanks in advance for any helpful input!

You could try flashing a custom recovery to it. If it works, then your bootloader is unlocked.
Nice! Such a simple solution. Thanks so much. Never would have thought of that. Over-thinking I guess. Will try this when I get home. Thx again!

your info is wrong, i never lock my bootloader and got all updates from (MZ604) 3.0 to 4.1.1,
my xoom is a verizon 3g but wanted to get jb, i load the 3.0 wifi and took all update, infact this 4.1.1 update work much better than the zip format...
That's what I thought but I read that here at xda, so I was a lil confused. Anyway, thx for the input!

Yeah same concept as the galaxy nexus. Plenty of people unlock the bootloader so they can root but do nothing else and continue to receive OTA updates.

[Q] This device is unlocked asus

Hi all, new to the site.. I have been trying to find sites on google to help me understand better about unlocked tablets.
I recently bought an Asus TF300T transformer pad on ebay, the seller told me everything was in excellent condition except when the machine is powering up, there is a message in the corner that says ' Device is unlocked'. I started researching on this a little and Ive found that the asus tablet has its bootloader unlocked, and it leads to rooting.
I really have no desire to root, this will be a present to someone i care about. Unfortunately i cannot return the item as the seller has stated nonreturns are available. So my question is, if i happen to leave the bootloader unlocked, but not root at all, is there any longtime problem that will occur? Im worried about not being able to update to the latest software. Hope Im in the right place asking this question.

Ok, there is no long term issue with unlocked device. The pros: you can install custom rom/kernel to make your device runs faster. Cons, you will have to manually upgrade your firmware, the OTA update is no longer works for unlocked device. In short unlock without rooting or unlock with rooting have NO EFFECT on your device,

Hi buhohitr, thanks for giving me that answer. I also forgot to put this down but can the tablet, being unlocked that is without roooting, can it still download apps from google store without any problems? and will the apps run just as it would on a locked tablet? Thank you again for your previous answer, appreciate it.
As the other guys said, the only things that change are the lack of OTA updates, the manufacturers warranty is void due to the unlocking, and that the user can (whenever they feel like it) install a custom ROM.
Everything else remains exactly the same, like being able to use/download apps and stuff.

[Q] Questions about root and Bootloader

Hi guys...
so, i bought a Razr HD XT925 and it still didnt arrive, but till it happens i want to be ready to root the phone, so i can install titanium backup and erase some **** that will come like some google apps.
i've read some threads about rooting the phone and i realized that a lot of people talk about this "bootloader"
i had a galaxy s2 and i've never had to worry about this, but in the root threads of Razr HD i see people arguing about it...
i dont know if the phone will arrive with the last update(4.1.2), probably will cause its a long time this update has been out...so i have the following questions:
1) If the phone comes with whether 4.0.4 ICS or 4.1.2 JB, do i need to do something about Bootloader beore rooting it? if yes, what?
2) what's the best way to root? any link for a good thread?
i just dont want to get the phone and in the first day screw him up...
that's why i need to ask this.
thanks in advance

When I bought my phone, it was on JellyBean. I used the Motorola instructions to unlock the bootloader (It seems to work in all Razr HD except the US / Verizon ones where you need to have the DEV edition).
Then I flashed recovery http://forum.xda-developers.com/showthread.php?t=1973904
And then installed SuperSU http://download.chainfire.eu/298/SuperSU/

thanks mate! i will sure try this in a few days.
so after doing these 3 steps, the device got Rooted and working perfectly?
I wonder why is it necessary to unlock this bootloader. why i didnt have to do it in the SGS II? maybe cause Samsung already let it unlocked?
i realized that when i unlock the bootloader i lose the cover by Motorola, so, is it possible to "lock" the bootloader again?
edit:
i saw this thread: http://forum.xda-developers.com/showthread.php?t=1943851
this one doesnt say anything about unlocking, maybe the script does itself?

Yes, I remember that when I bought my phone I just root it without unlocking the bootlader (using the MotoChopper tool I think), I waited 6 month until warranty time was over and then I unlocked the bootloader
I'm not really sure of any of this, but i think that...
With locked bootloader you can't install custom ROMs and you will lose root if you OTA update your device (have in mind that there is currently there is no way to root KK in this device).

so, basically, it isnt necessary to unlock the bootloader to root the phone?
i really dont want to flash custom roms. not right now. i just want to root the phone so i can use Titanium Backup to uninstall some apps that i don't use, which will just waste my memory and battery!
edit: i just read that there are 2 programs. this motochopper and one called motopocalypse.
the motochopper is to root the phone and the other one is to unlock bootloader. and you can't unlock bootloader if your device isnt rooted.
so i can just use the motochopper, root it, and the device will be rooted and still working fine, without bootloader unlocked and i would still have the cover from Motorola? am i correct?
If you upgrade to Kitkat on a phone with a locked bootloader, then you will lose root. No way to carry it over the ota and there is no way to root it once you are on Kit Kat. This must be the 100th time this has been stated.

Stupid me, I didn't read. You have an XT925 so you can "legally" unlock it, no exploit needed like it was with the XT926, so you should still have the ability to sideload root on Kit Kat, like those of us with unlocked XT926s. So, disregard my incoherent ramblings earlier! :silly:

They can tell if you rooted it or not. When you start to boot up into stock recovery, you'll see a QE code on the Andy screen. A qe code of 0/0 means it's not rooted and it's never been rooted.
1/1 means it's currently rooted and it's been rooted before.
0/1 means it's currently not rooted but it's been rooted before.
At least, that's what has been guessed as to what the values mean, but definitely, if it's 0/0, then the phone has never been rooted before. Any values other than 0 to the left or right of the slash means the phone has been rooted before, which means you're warranty is voided.
So, they can tell when you've rooted it. And there's no known way of clearing those values out.
In any case, if you're going to root, you might as well unlock it as well because they can determine if it's been rooted anyways, which will void your warranty.

Forgive me if im asking something already answered. If you have a locked bootloader and on KitKat, is it possible to flash with sbf to an earlier software version, root, then just dont update? Or if the bootloader is locked does this mean that you cant flash anything at all? I only need root, probably like everyone else on KitKat. LoL. Just curious if theres a way to flash to an earlier version. How do you know if your bootloader is locked? Im not familiar with this version.

Once on KitKat, you are stuck. You cannot revert back to a previous version (you WILL brick your phone).
A little research goes a long way. This has been discussed to death since KitKat came out.

That's been going on since ICS, I believe. So, it's nothing new. I remember when the news came out about it a few years ago. I've seen it on my Droid X2, Droid RAZR MAXX and now on my RAZR HD.
I don't know if it's only on Motorola phones or all android phones. All my Android phones have been Motorola with the exception of my first Android phone, which was an LG Vortex.

I've heard about it on some Samsung phones, and they go even farther and track how many times someone has flashed roms and such...Chainfire has some tools just for them. Look up Triangle Away.
yep, i had a Galaxy S2(which i dont have anymore cause i've been stolen), and in my first day with it, i rooted, flashed a custom rom, and then some months after, the usb connector stopped working properly. and the phone still had smth like 4 months of warranty...
i had to do a lot of things to reset it.
flash stock firmware with odin, then use this triangle away, then unroot, etc etc etc...well at least i could reset it and send to warranty without they knowing it
