Unlocking bootloader after taking JB update?

So I have, until now, been content with a locked boot loader on my tab. I rooted it back on .30, but installed the jb firmware when it was released, so I no longer have root. I've been looking into it and it looks like there's a way to restore my root, but that's not really my question. I'm wondering if there's a way to unlock my boot loader now and start trying out some custom ROMs. On the Asus website it says the tool is only available for ICS. Has anyone tried it anyways? There's no workaround that I missed, is there? Apologies in advance for my noobieness and thank you for any input.

If you check the thread here he says he unlocked the bootloader after updating to JB, so yes apparently it works anyways.

So then what was his mistake? Using CWM? Trying to install an ICS ROM after taking the JB OTA? Haha saying "device unlocked" on the boot animation is meaningless if it boot loops.

I think his mistake was trying to install an ICS rom, after updating to JB. I'm assuming he didn't know he was basically trying to downgrade :/ which I don't think anyone has managed to do yet as far as I'm aware...

CWM or TWRP?

I finally got my replacement Infinity from Best Buy and it seems like its a keeper Given that some decent looking JB roms have appeared I am going to unlock. I am having some indecision about which recovery to use before the flash-fest begins.
I use TWRP on all of my other devices but after reading the thread in the dev section I am a little hesitant about using it on my TF700. Specifically, it seems like some people have been having problems restoring because TWRP doesn't deal with restoring /boot properly. I had exactly the same problem with my Prime and all of my TWRP nandroids were useless without flashing a kernel after restoring. This is a bit of a problem if this happens with the TF700 since there are no custom kernels available yet.
These are my questions:
- How common are the problems with restoring TWRP nandroids? Can most people successfully restore with TWRP?
- How well does CWM perform? Looking at the thread it seems like it works just fine or am I missing something?
I appreciate all of your input. Thanks!

To be honest i have the same problem with CWM ,it doesn't restore /boot so you can't switch between various roms by just just restoring your backups.This beeing said i didn't had any issue with TWRP and so far is more user friedly than CWM.

I have been using TWRP exclusively and have been going back and forth between 4 different roms, restoring from each, and have had zero issues. I believe the problems reported related to those who had flashed the TF300 JB update and replaced their bootloader with one for TF300. If they hadn't made a full nandroid prior, I think they were stuck with that bootloader until the most recent .30 ota update. I could be wrong, but I think these issues you heard about were related to the TF300 bootloader.

Thanks okantomi. I'll try TWRP but keep the stock rom on /sdcard in case of emergency. Now, which rom shall I try...decisions, decisions

Of the JellyBean Roms, the 9/14 versions of Baked Black Bean and the CM10alpha work well, but the latest version of CM10 (9/18) won't boot all the way into the os. Hiemashu is working on it. Also the TEAM EOS Jellybean has issues (random reboots and newest doesn't boot). My best recommendation would be to flash the ZEUS v4.0 ICS Rom. It's complete and nice and fast. You won't be sorry. Read all of the OPs and follow instructions. Have fun!

The problem with CWM can be solved quite easily. It doesn't restore the kernel properly. So therefore you have to flash the kernel after you restored.

Are there flashable kernels out there that I have missed or are you talking about flashing the stock kernel blob with fastboot?

Rooting latest firmware

I have asus tf300t I never rooted on ics either and have bootloader locked. I updated to latest via ota updatesz is there a way to root without unlocking bootloader any link will be helpfull. Or guide me on how to unlock bootloader and then root.
Thanks in advance
Sent from my LT18i using xda app-developers app

You can unlock the bootloader with ASUS's official app on their website, search up transformer tf300 and there will be a .apk that you can install to unlock it. After that, use fastboot to flash a recovery such as cwm or twrp, then flash a root package or a ROM with root. Hope this helped!

Oky thanks can you send me link on how to flash using fastboot on tf300? Also cant I just keep factory room and root that if ao how any links will be helpful thanks

You can read this thread for more information about unlocking and rooting, but before starting anything, please think about it and be aware that unlocking the bootloader will:
- void your warranty
- prevent further OTA updates for your tablet from Asus
Cheers

Before you read, there are some considerations: I unlocked my device last night and I am running either .29 or .30 of the ICS firmware. I also, never connected the device to my network until after I unlocked it. So if you have a TF300T runing the above versions of ICS, then it should work for you. You said you: "updated to latest via ota..." If you did this, you are on Jelly Bean and at the moment, there is no known way to make your device "unbrickable." You can still mod it, but if you dont follow directions perfectly, you could easily brick your device. Now without further hesitation....
Here it is, the TF300T unlocking guide:
Go to the Asus site and download the v7 tool
copy the v7 tool to the tablet
run the v7 tool on your tablet from the tablet GUI
it will install the v7 unlocker application
run the unlocker application from your app drawer
you have to accept a few agreements
click the unlock button
after that, your device will reboot
This is how to confirm that the unlock tool was successful: After your TF300 reboots, you will see the normal ASUS logo in the middle and some very small text in the top left will say: "device unlocked."
Now for rooting:
If you already have root, and you want to keep your exiting root access, make a backup after unlocking. The backup instructions are included in the "unbrickable" method. If you do not have root, just make a backup anyways. Then you can flash a ROM onto your device that is pre-loaded with root.
I hope that answered your questions.

Thanks but no I am on jb. So I will just wait till a solution comes out for unbrickable before trying anything dont want to mod ot just want tp remove a few apps

It seems someone always bricks on something that was thought to be unbrickable. No I'm not suggesting you go forward, just the opposite. As long as you aren't sure about change enjoy your tablet as it is and just forget about the apps that bother you.
Good Luck!

Odd issue with cwm for JB.

Ok I hope you all can help sort something out for me. I just got a refurbished TF300T a couple days ago. I unlocked it in ICS and then it forced the OTA of 4.1.1 on me. I had no problem getting ADB drivers in and flashed the jelly bean recovery. I rebooted into recovery and there was cwm. I tried flashing the rootzip that is out there but it did not work. I then tried to do a bakup and it failed. I then realized i could not see emmc only sd.
Any ideas.
I have a rooted modded nooktab so i am somewhat familar with these devices but i am stumped.
Thanks for the help

I'd try manually flashing the firmware and then flashing CWM again, or TWRP which some users will argue is much better than CWM.

Thanks for the tips. Yea in a tough spot. Not sure what to do. I will,search around. You think flashing the firmware will work. Should i flash stock recovery too.
Odd issue. Wonder why they did this?

Just read the post again if you are still on 4.1.1 the disreguard what i had mention theres probably away to fix which im sure some one can help but what i had talked about was the 4.2.1 jb update attempting to root on that is a no go. So just ignore that post. I'm on stock 4.2.1 but unlocked bootloader so can't help there cant go any further myself at the moment.
In my setup menu theres an option to add seperate users some seem to think that it encrypts the information so another person who has access under another user name cant see another person info. Sound logical to me but really messed things up for us.
Now still thats all just speculation no one knows for sure what the exact issue is with the 4.2.1 update is yet but best advice is to wait till it's figured out.

Reflashing stock img will flash back stock recovery, so I'd just do what I said, you should be good.

Numb on this.... Need help!

Hello,
I have tf300 everything stock on 4.2.1. But I want to try a custom rom. But I have afraid to brick my tablet. He is under warranty!
I read so many post but I'm confused and I don't know what is right for me... I need the most simple way to not make "****"!
Thanks
