I have Asus Eee Pad TransformerTF101 with an unlockbootloader is there any way to get the device back with locked bootloader ?
and how i can lock the bootloader again ?
The bootloader does not 'lock and unlock'. What are you trying to do? Unroot the device? Reinstall android OEM recovery and return to stock?
The 'locked' or 'unlocked' bootloader simply refers to the fact that the bootloader is encrypted, and for some versions we have the encryption key and can manually unlock via NVFlash to restore a bricked device, yet on other versions the bootloader key is unknown thus it is considered 'locked'.
I suggest reading up a bit more. If you don't know what you are trying to do and able to explain your problem then we can't possibly help you.
There is no concept of locked or unlocked in the tf101 bootloader, in the most general sense it is unlocked as it allows booting of unsigned kernels, and flashing of unsigned blobs.
the leaked key allows lower level communication (bootrom) with the device and can recover from bootloader errors.

Now i would like to return bootloader lock
thanx
You are not "back with a locked bootloaded" please use the right terminology..

Maybe you're trying to say you want to unroot and return to stock?
Because the bootloader questions have been answered for you

I'm curious if the fellow is confusing the 'bootloader' with the recovery mode? From the sounds of it...he either has little understanding of english and can't/hasn't read my guide or is just dense, I'm leaning towards the first scenario

this may be a dumb question but after unlocking the bootloader will i still be able to return this to bestbuy? The tablet isn't bricked or anything and runs fine. If i return to stock and relock the bootloader will i have a hard time trying to return it?
Thanks
If done right, you shouldn't.
And by done right , you mean returning to stock and relocking the bootloader right?
Basically.

I wouldn't think that they would have a way to even know that the bootloader was unlocked. Do you think they even check? The only way I can even think would be to run fastboot reboot bootloader.
personally I don't think they check. But you should always rather be safe than sorry.
thanks guys
Hey guys I have been reading through this forum and I think I get most stuff now. There is only one thing confusing me, when talking about bootloaders and unlocking them, everyone says its irreversible and you loose warranty and drm keys.
My question is, why? Can't we just backup it with CWM or similar? Can't we just make a backup when we receive the device from factory and then if we need warranty for something can't we just flash back and put everything original, including bootloader and stuff?
Thank you

Your warranty is never truly lost. Just remember, if they can't turn it on, they don't know it was rooted.

Ok, well the technical answer is once you unlock it, it can't be locked. Recovery does not back up your bootloader. A better alternative is flashing a different bootloader. There are some phones where the engineering bootloader used by OEM devs is available, so you can always go back to the stock bootloader.
EDIT: Actually now that I think about it, you can make a backup. I honestly have not dealt much with Samsung phones, so I am not sure if it is the same. But when you first root an HTC you take an initial image, which you store on your SD card or computer and you use it to unroot. When you unroot using that method it sets your bootloader back to factory. Also when you use a factory image, such as a PDxx.img and flash that through hboot, it gives you a stock bootloader as well.

sorry if I'm being thick, but since the bootloader is part of the partition, what stops me from backuping all the partitions, unlock the bootloader, and then after some time flash the original dumped stuff?

Hey, you can try it. That is a very sensitive partition to mess with. The main issue is, how many times have you flashed a ROM and for some reason it just doesnt flash right and you get a boot loop? Easy fix, wipe everything, reflash, good to go. If you flash the bootloader and reboot your phone and something went wrong with the flash...you have a hard brick. No coming back, period. So, experiment wisely. It is the same thing with flashing through terminal. If you get 1 space, 1 character wrong in the command line...hard brick.
actually I don't own a smartphone yet, but I'm going to soon. Since I'm well versed in Linux I was checking out the Android OS in general and that question popped up in my mind and I just couldn't find any info about it. Does that make kernel flashing dangerous too, since it's in the same partition as the bootloader?

No, kernel flashing is fine. A bad flash just ends in a bootloop, no big deal. Bootloaders and radios..those are the ones you have to be careful with.

Alright, thank you very much.
Actually, it just struck me, why is it dangerous if it doesn't flash properly, the recovery partition is separate and you can make the device boot from it right?

I am assuming you could if you have one backed up. But when a bootloader doesn't flash right and you get a brick, you can't even get into recovery. Most of the time the phone won't even power on. Because booting into recovery requires the bootloader.

New question, if you are still around. What exactly is a locked bootloader? Is it just a bool in the bootloader code? Where are the DRM keys and why are they lost?

It depends on the device. A bootloader is usually unlocked by an unlock.bin for that device. I'm not an expert on bootloaders though...

A locked bootloader doesn't allow you to change key parts of the system such as a kernel. So you can still root your phone, but all of the custom ROM's have to use the stock kernel. So if you are on a gingerbread stock ROM, you can't run Ice cream sandwich because you can't change kernels. The DRM keys are what is used to encrypt the bootloader, so if you unlock the bootloader the keys are lost.
Hi,
I followed the steps and procedure on htcdev.com and the process to get the HTC rooted as given by DoomLord, but while trying to get it s-off, going into the bootloader, it shows unlocked, but still gives s-on. Is that a problem? Any way to rectify this?
Also, in the process, somewhere down the line, the pen useablity has disappeared and am unable to use the pen. Tried factory settings and restore from bootloader, but no use-I use the pen feature heavily. So any way of getting it back?
Please help
Thanks in advance.

I sort of understood that but on the bootloader, it still shows s-on rl. so was thinking if that was any problem or if it could just be ignored. this is my 1st android device so kind of new at things.
in any case, the pen glitch got solved-turns out that there was some new setting unlocked which had to be tweaked to make it work-hadn't done it with the new device.
Thanks anyways for the help..

No, it cannot be ignored (in most if not all cases). It probably is a problem, but if you tried again and it still results like that (or it tells you that you already have S-OFF), then you can continue the rooting process (hopefully it will work, but it would be strange).

nope not S-OFF, it only puts *** UNLOCKED *** at top of bootloader AFAIK
It gave the same result when tried again. So went ahead with the root procedure. Got superuser but nit sure what to do further. Will figure it out next weekend. Got an exam on.the 8th..

Actually it is. If it was done properly (and successfully), it is S-OFF.

asus says there is no way to relock but we will see if the devs here cant figure something out
You CAN NOT Relock. The prime devs worked on it for months, and couldn't get anything working. If you decide to unlock you void your warranty and no longer get official ota's. You do get access to custom roms though.

Correct. The only reason I would recommend unlocking, is so that you can install a custom rom. If you do not want to install a custom rom you shouldn't unlock.

Everything works on the tablet still. Asus just has your SN blacklisted

you can update, however not by ota. you update by flashing roms that are updated.
There may not be a way (yet) of relocking the bootloader, but there should be a way of preventing ASUS from logging the serial. From the decompiled unlock tool, the tool is sending something to https://mdm.asus.com/DMServer/DeviceState. However, that may not matter. In a previous thread about this (for the Transformer Prime), one developer found that the result returned from the ASUS server is stored in a variable that's never used

I doubt they blacklist it, they did after all provide the tool. Of course, they do say they won't officially support if you do unlock, but that doesn't necessarily mean they wouldn't if you asked them.

AFAIK the unlock tool requires an internet connection, this is for the purpose of notifying ASUS on what tablets have been unlocled

Is there a way to obtain root without an unlock? Sorry new to this game still reading
I have been enjoying the stock asus rom for now and just want root access but don't feel voiding the warranty less than 24 hours after buying it from best buy.
Really want to try the 6 axis controller for some emulating and who wouldnt love some overclocking (from what i have read this is possible on stock kernel)

SOMEHOW, the "Device is UnLocked" has disappeared from boot screen
As I mentioned here just earlier today (or the full thread here), the "Device is UnLocked" has vanished from my boot screen. The screen that first shows up after you start your TF300.
I had gone through A LOT the past couple of days trying to UN-BRICK my device. Once I fixed my TF300, the "Device is UnLocked" is no longer in the upper left-hand corner anymore.
I have no clue what I did, or even if it's really "Locked" again. All I know is that it's gone. I think I might have accidentally tweaked something that might have just turned off the actual "Device is UnLocked" text. But I don't know...

OK. I have not gotten a clear answer out of all the forums i have read. simple question
Can I load/use fastboot on a locked (and never been unlocked) TF300T?
I cannot get the USB icon to load up for the life of me. I get wipe and android. Any help would be greatly appreciated. thanks

LoL.
I would unlock. but i have had way too many issues with my asus tablets in the past. i dont want to give them a reason to say no to my warranty. I am rooted though. I cannot update to JB for my life. So i was going to flash the blob file but I cannot get to fastboot. I am not sure what to do anymore. On my original transformer, i was able to flash back to stock using nvflash from a desktop. Not sure if it was nvflash exactly, but whatever it was, i flash the stock rom from my desktop. From my hours of reading these forums, i have not seen the same option for tf300t.
