Re-lock bootloader - Transformer TF300T Q&A, Help & Troubleshooting

hi,
i have asus tf300tg,rooted and unlocked.
there is a way ti re-lock bootloader? i want to restore the tablet to original state when i buied it.

It has been answered here plenty of times, short answer is: No, you can't.

ah...ok...thanks

I have this build out of the box US 9.4.3.30 then the updates is available and I didn't install but instead I did unlock,nvflash,cwm then root. Any advice on what should I do:
- click this update now it will still work or not since I'm already unlocked and might possibly brick my device?
or
- safely install the update but I will still be unlocked?
or
- ignore updates and just flash custom JB ROM?
Thanks!

This means you're still on the ICS bootloader. This is important to note because of your questions below.

Taking the JB upgrade from ASUS is the only way to upgrade the bootloader. Whether you take the OTA upgrade or do it yourself, you will have to perform this step at some point if you want a custom ROM based on the JB bootloader.

As stated before, you cannot re-lock the bootloader. This includes via ASUS upgrades... your bootloader will remain unlocked.

This will depend on the custom ROM you want to use. Do your research before moving forward either way.

Thanks for taking time to answer my question, I'm planning to use Hydro and I understand that I need to update to JB first. I'm kinda new to TF300 so I'm afraid to mess up so I wonder since JB update is in my notification can I install it or it may brick my device since it was downloaded while I'm completely stock but now my device is unlocked and rooted?
Here's what I'm planning to do:
-Update using the JB OTA in my notification bar
-Install CWM JB compatible
-Install custom rom
OR
-DL the latest JB firmware from ASUS
-Install CWM JB compatible
-Install custom rom
Thanks again for your help!

TF700 Root on JB

As of right now, there is no way of rooting a TF700 on the latest stock firmware, correct? I was reading through the All About the Infinity thread and there was a method listed but I'm not sure if it's been updated to reflect the latest OTA. Is there an official thread where an announcement will be made when a method of rooting has been discovered?

To root JB directly, you need to UNLOCK your device. If don't want to unlock then you have to downgrade back to ICS .30 in order to root.

Will there be a way to root without unlocking in the future?

Currently the only thing to get root in JB with locked bootloader is: downgrade to ICS, root, use OTA root keeper, run OTA upgrade manually.
A more direct way is only possible if someone discovers a new security hole in JB - if and when this will happen, is impossible to know.

Interesting but makes sense. Question tho, if you have unlocked, rooted, installed custom rom, AND also updated to ASUS newest boot loader can you get back to a locked or unlocked ICS state WITH the OLD boot loader ? I am sure I know the answer tho ... And sorry if this is considered a double post to my other one.

From what I read in some other threads: you can downgrade to ICS 9.4.5.30, but not to the 9.4.5.26 bootloader.

yes, _that is correct, the only way you can go below .30 (back to .26...) is if you have a backup of your bootloader using NVflash.
Rooting question
I have the latest firmware update, running STOCK jelly bean, NOT unlocked and NOT rooted. If I use the ASUS unlock tool, will that unlock my tf700 and root it? And then I can just flash custom recovery and load CleanROM.. correct? Coming from samsung vibrant, galaxy nexus, nexus 7 and tf101 here.

No, unlock is just unlock, you need to do root separately. Follow this threads, he's doing the same things you're doing

You say that for root, the device has to be downgraded first. Isn't it the same for unlocking? Is it possible to unlock JB without downgrading to ICS?

I'm by no means a pro at this, but from my research, you no longer need to downgrade to ICS. This is a pretty old thread. There is an unlock tool now available for JB

If you do everything correctly, you won't brick your tablet.
Since your bootloader is unlocked, you won't get the OTA update, so you'd have to install it manually. AFAIK you need root to manually install an OTA update (by copying the dlkpkgfile to /cache and creating the corresponding command file), so it's easier to install TWRP first.
The bootloader stays unlocked when you do all this.
thanks

To Root? Or to unlock the Bootloader?

I'm on the latest official OTA of 4.2.1
Do I need to unlock the bootloader to root?
I read this http://forum.xda-developers.com/showthread.php?t=2187982
and I'm still not sure whats happening... Do I need to downgrade to root, and do I need to unlock the bootloader to flash TWRP?
I know a bit of what I'm doing as I have rooted and flashed roms on an htc desire and a samsung s2x (t989).
On 4.2.1 theres the occasional hiccup and freezes when I use chrome... Is this still an issue in the custom roms? Also my Settings app crashes when I try to load the "Running" tab in the apps section of settings lol
Can someone point me in the right direct?

Well, you have two basic options:
Get root without unlocking.
That is good, if you want to stick with stock ROM, but want to run Apps that need root access.
Or if you don't want to unlock for any reason.
More details in this thread: [JB ROOT] motochopper works! (Root JB 4.1.1 & 4.2.1 with locked bootloader!)
Unlock and install the patched TWRP for -4.2.
This will allow you to root stock ROM easily or you can install custom ROMs.
Be careful: You have the boot loader 4.2, which means you need to pick the patched TWRP for that boot loader and you need to pick one of the ROMs supporting the 4.2 boot loader.
People have bricked their TF300Ts not using the patched TWRP -4.2 version.
There are currently only two ROMs available, but more should be coming soon, as Asus has finally released the new kernel source code.
If your preferred custom ROM supports only the 4.1 boot loader, you need to downgrade. Or just wait a little, as you like...

No and yes.
You can use the tool from the tread above just get root; no downgrading, no unlocking.
But yes, if you want to install TWRP, you need to unlock your device first.
You only need to downgrade for installing a custom ROM that does not (yet) support the 4.2 boot loader.

I have not used stock ROM for a while, but generally people report that most custom ROMs run much smoother than stock Asus ROM:
I would suggest downgrading ti the 4.1.1 bootloader, as there is a much larger variety or ROMS available.

Thanks was a lot of great information! I rooted my pad and did a few speed optimization things such as re-trimming and now its much smoother! Maybe I'll try a custom rom later but as for now, I'm happy with the updates that Asus provides

I'll keep that in mind but I believe there should be more soon as f69m, stated that asus release the kernel for 4.2
I signed that petition in your signature as well
I'd say go for the 'full experience'. Having an unlocked device also allows you to reflash ROMs at will and can also help in a pinch when it comes to backups/restores. Also, if you happen to lose root, it's easily re-rootable through the bootloader.
I'd just be careful of the current TWRP 4.2.1 recovery blob. I just flashed the one released this morning and I am currently getting this weird double screen thing. Best bet is to sit tight at the moment; an update should be out shortly.

Well, stay away from the TWRP 2.5.0.0-4.2 provided in some thread today, but TWRP 2.4.4.0-4.2 should still be working fine.

[Q] Assistance getting from stock to kitkat

First, thanks for the assistance on this thread!
I am new to this device and have been exploring the section to help a friend. Since I want to get it right the first time, i'd like to verify the process and get advice from the pros!
It appears that the device is on the stock rom, 4.1.1.
So, from there I plan on doing the following. Please correct me if i am wrong on something!
1. Install the universal naked driver: http://forum.xda-developers.com/showthread.php?t=2386956
2. Update the device to the latest firmware and JB rom: http://forum.xda-developers.com/showthread.php?t=1697227
3. Root and unlock the device (now on 4.2): http://forum.xda-developers.com/showthread.php?t=1845377
4. Install TWRP recovery (preferred)
5. Flash new rom
Is this the correct method? Is this the best method? Is there a easier way of getting to a state where i can flash a 4.4 rom?
Thank you in advance!
For #2 I would use the built in OTA Updater to update the device in the Abbout page (because its "easier")
The rest look fine to me, I did the same procedure

OK so for the unlocking, lots of people are having trouble unlocking on the 4.2 Stock ROM. You may want to try unlocking with v7 on the 4.1.1 ROM, then upgrading to the 10.6.1.27.1 via fastboot and then you can follow the outline here to flash a kitkat ROM: http://forum.xda-developers.com/showpost.php?p=48508679&postcount=7

Well for some people the 4.2 ROM won't unlock using the tool, leaving them with a locked bootloader and inability to flash ROMs. Fingers crossed it doesn't happen to you.

He probably just wanted a reconfirmation that it really works. I'm wondering the same Btw, because rooting for me normally means also to have a modified system folder by busybox or AdAway and all my previous phones did not allow to simply use an OTA file.
Would you be so kind and elaborate more? Thanks a lot!

Every time when update is coming you have to flash stock boot and recovery (current version).
Because, rooting process changed boot. And to get root you installed TWRP (custom recovery) before.
You don't need relock bootloader only, cause update will do it self (in most cases).
Finally, you have to unlock bootloader and get root again.
