I've searched all day for info on wether it is possible to install recovery without unlocking the bootloader? Right now all points to not possible, but please give me a deffinate answer.
Thx in advance.

I was looking only half of a day and then got to this post - thanks.... Damn you ASUS for you wicked tricks
I like CWM on my Desire phone... kinda want me riverdancing... void my warranty
Someone correct me if I am wrong but changing out a recovery.img requires bootloader access. Unless a dev can crack the bootloader or the manufacturer allows it, def hard, help that helps.

.21 downgrade & unlock bootloader
The 9.2.4.21 firmwware presently cannot be rooted. The way to get root is to use version 9.2.4.15 or earlier, (I used .11) using a linking trick and then use ViperMOD to complete with root and unlock.
Tutorial by Wolf849 - over here - will get you to .11 firmware and working super user / root access.
Then use ViperMOD PrimeTime by - viperboy - which includes an option to install Clockwork Mod recovery and install the Asus Unlock Tool.
Once the bootloader is unlocked, you can install a custom recovery, such as CWM, CWM Touch, Open Recovery or other as you wish.
Unlocking does have the penalty of voiding any warranty and you might possibly get into a boot loop, which can be resolved with;
Code:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=1 count=13
Roach2010 has a thread here explaining the boot loop issue in better detail and Diamondback has some very helpful unbricking tips.

Well Guys,
I finally got my hands on my dream phone, the N1. Hope this guide helps some n00bs out there like me.
Here is how to unlock the bootloader, root and install clockworkmod on the baby.
DISCLAIMER
I AM NOT RESPONSIBLE IF YOU BRICK YOUR DEVICE AND THIS WILL VOID YOUR WARRANTY AND ALSO WIPE ALL YOUR DATA TO FACTORY SETTINGS.
CREDITS
TO ALL THE VARIOUS WEBSITES WHERE I READ ALL THE INFORMATION MENTIONED BELOW. NONE OF THE BELOW IS MY WORK AND I TAKE NO CREDIT FOR IT.
HATS OFF
To all the developers who made this possible. superboot is work of Paul from Modaco, clockworkmod is work of Koush.
Step - 001
Install Android SDK from here.
Step - 002
Connect your phone to the PC using the data cable provided. If the drivers are installed successfully well and good, else download the one's from here and point windows to the folder where you extract the above drivers.
Step - 003
Open
Code:
settings - about
and note down the build number
Step - 004
Download Superboot from here depending on the build number noted above.Extract the archive to a folder.
Step - 005
Turn off the phone, boot into bootloader mode [press track ball and after that press the power button]
The phone will go into download mode. Connect USB Cable.
Navigate to the folder of superboot above using Windows command prompt.
Issue the following command
Code:
fastboot-windows devices
If this line does not return anything, do not continue: Your computer does not detect your Nexus.
Unlocking the Bootloader(this will void the warranty and also do a factory reset)
Code:
fastboot-windows oem unlock
The phone will display a warning, use the volume up down button to toggle between yes and no, we need to select yes, once yes is selected press the power button to confirm your decision.
The phone will reboot.
if you get the following error
FAILED <command write failed <Too many links>> error
ignore it and try giving the oem unlock command again and it should say bootloader already unlocked. Do not proceed until your bootloader has been unlocked.
Rooting
Boot the phone into bootloader mode. naviagte to the "superboot" folder in windows explorer. Double click the file "install-superboot-windows.bat" and viola you are rooted.
Installing recovery (I used clockworkmod, you can also use AmonRA)
Download the latest CWM from here, download the .img file and once downloaded check the md5 with the one on the link above. (passion is the name for Nexus One).
Put the above downloaded .img file in the 'superboot' folder and rename it to a simple name say "cwm.zip" (without the quotes)
Boot the phone into bootloader mode again.
Navigate to the superboot folder from Windows command prompt.
Issue the following command
Code:
fastboot-windows flash recovery cwm.img
You are now rooted and have installed ClockworkMod recovery.
I would advice you to flash a new custom ROM right away, do not boot into the stock ROM as it would end up breaking CWM. In case you want to be on stock ROM and still have recovery you need to do the following.
Boot into the stock ROM.
Connect USB.
Navigate to the superboot folder.
Give the following commands.
Code:
adb-windows shell
su
mount -o rw,remount /dev/block/mtdblock3 /system
rm /system/etc/install-recovery.sh
rm /system/recovery-from-boot.p
reboot recovery
Now flash CWM again as described in the step above.
How to boot into CWM when phone is switched off.
press the volume power down button and while it is pressed press the power button.
The phone will boot into a white screen, wait for some time (7-8) seconds, some checks will take place, once those checks are complete use the volume buttons to go to recovery option and use the power button to select and you are into ClockworkMod.
Moderators Please move this to correct section if I posted in the wrong section.

i guess unlocking the bootloader is very conventional..
no one unlocks the bootloader now....
there are many direct rooting methods available including one click root , universal androot, superoneclick etc, where we can root and also unroot afterwards thus the warranty is not void..
but in unlocking bootloader warranty is void and is also not very safe method .
while other methods are extremely safe, requires only one click...
you should have researched before unlocking the bootloader.
though you are from india like me so warranty void is no criteria as nexus one is not sold here officialy.

Precisely.
Although I never heard of HTC denying warranty(with unlocked bootloader), unlocking the bootloader is not necessary.
Just start with Rooting(super one click, or z4root), install recovery with adb or android shell, and go from there.

I guess it depends what you want your device to ultimately be capable of doing.... Being a person who has also researched... I personally needed to unlock the bootloader to flash a custom rom, although rooting is a vital aspect when customising devices, if you want to maximise the potential then sometimes voiding warrantee's is to be expected (note there are also ways and means of reverting most mods back to factory standard if needed )
Each to their own
Well it was my personal choice to unlock the bootloader, I wanted to do it just for the heck of doing it
The tutorial was made so as to help others and that is why "the void warranty" thing was mentioned in bold and red.
I was aware of methods which will root and not void the warranty but I wanted to "void the warranty" as we do not have it in India and yes the main reason was custom ROMS, my first phone the Samsung Spica (still own it) ran stock ROM for only a month and the N1 ran a stock for only 12 hours ...

I recently got my TF201 and soon as I got it home and turned on the WiFi, it updated. I put "Android System Info" app on it so I can see most of the system info, and I've ran the Unlock tool from Asus and have the Bootloader unlocked.
So my question now is, since when i boot the tablet, the top left says "Bootloader unlocked", can I flash CWM and then a rom, or do i still need to get root access and can I?

With your bootloader unlocked, you can install CWM without root access. See my response here (http://forum.xda-developers.com/showthread.php?t=1585046). On the link in that thread, use the "non-rooted" method (fastboot) to flash CWM. Then you can install your ROM.
Confirmed, this is what I had to do.
Unlock, flash cwm (TOUCH VER. )
Then flashed Virtuolous newest rom.
It would be nice for a guide, or a tuturial for someone on a locked, and stock .21 rom for the prime

A guide/tutorial for a "locked & stock .21" is impossible since you need to unlock your bootloader.
And there are plenty of guides/tutorials on how to flash CWM onto your unlocked Prime.

It's quite possible...someone would just need to run a step by step including the unlock apk then move onto the steps of fastboot load of CWM. I agree that all the tutorials are there, but it requires a little hunting to piece them together.
This is where I went to unlock the Bootloader:
http://transformerprimeroot.com/tra...ow-to-unlock-bootloader-on-transformer-prime/
had to visit the page on the tablet cuz it wouldn't download otherwise
The question though, is once I install CWM and a ROM, do I have Root access, or can I only flash Pre-rooted roms?

Well yes, sort of. There are guides on how to unlock the Prime. Guides on how to flash CWM. And guides how to flash a custom ROM.
But the way the question was worded, it was how to flash to an unlocked, unrooted .21 Prime. Which you can't do. Flashing pre-supposes that you've unlocked it.

You have root access if the ROM you're installing is pre-rooted. If you install a ROM that is not pre-rooted you do not have root access. Whether or not you can root that ROM is another matter.
Why would you install a custom ROM not pre-rooted?
So call me blonde, dumb, or just flame me, but im sleep deprived on a daily basis so I'll ask a dumb question again.
Since I have my bootloader unlocked, all I need to do is flash the Touch CWM, and then a pre-rooted rom and I'm all set. No needing to gain straight up root access right here right now like i had to do with my EVO 4G just to be able to get into the Bootloader and put in the recovery

Correct. Just make sure to follow instructions to the letter. You'll need to flash the CWM using fastboot seeing as you do not have root.
Hi,
I was hoping if someone could answer a quick question for me. I did look around and I think I have one of my answers but wanted to check.
Can the phone be rooted without unlocking the bootloader? I think I saw that it can.
Does the Motochopper exploit work on the phone?
Finally can the bootloader be unlocked without using HTCDev?
Also, can someone tell me if changes made to the partitions via a DD stick?
When unlocking the bootloader for the tablet Z i xperienced some problems.
So I made a more extensive guide than the one from Sony

Wow, that's a long guide. Is the main/only reason to unlock the bootloader to install custom roms (can't this be done with just root access?).
I have root, but don't really wish to install custom roms. I don't have the bootloader unlocked, but I know it can be unlocked
why to unlock bootloader?
why to unlock bootloader?
1. u can flash custom ROMs/Kernels
2. u dont need to worry if the new firmware can be rooted or not as with unlocked bootloader u can always ROOT ur device
3. Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011/2012 line, so who knows may be Sony may give early builds of next android OS
Best guide I found online. Thanks!

I think it would be wise to mention not to forget to backup TA partition with DRM keys before bootloader unlock.
Thank you very much. This tutorial covered all the issues I ran into so I knew what to do.
Btw, the .bat for allowing unsigned drivers doesn't work on Windows 8. A quick google search helped me but maybe you might want to add that to your tutorial for other, less techy users.

if your bootloader can't be unlocked it means that you can root your device, but won't be able to install any custom firmware. But you can install XZDR recovery.
Once you get the bootloader unlocked what is the root method? Also, is there a different process for flashing roms?

to root device you don't have to unlock bootloader. Unlocking is for installing custom ROMs.
That I understand. Thank you. I was asking since i already unlocked the bootloader and am unrooted. What is the process to gain root at this point?

Use Flashtool. It can automatically unlock bootloader. Only unlock code 0xFBCD6A2B26CB8F88 is needed.
Cant figure out which file to replace and where it is. Can get my tab to recognize in adb devices mode but nothing is coming up when i type fastboot devices in adb. It is not recognized. I am stuck. Any help will be appreciated. I have got unlock code and the usb inf file but no light further.
Hi, guys! I'm new to modifying the Android OS, and have a question that I haven't been able to find the answer to, so I was hoping that some of you guys could shine some light on my situation. I have a HTC One Max (T6#UL), running 4.4.2 with HTC SDK API level 6.20 (If that's relevant), that I received from work. When I boot it into the Bootloader, it says that the Bootloader is locked, and S is-Off. What I want to do is root it, and install a new ROM, but I'm confused on what exactly to do in this case. I've read that because S is Off, this overrules unlocking, and I can go ahead and install custom recovery (TWRP) now. Is this the case? Do I have to FDR before doing it? What is the best method to go about this? Please let me know if you need any phone/bootloader info.
Thanks for reading, any help is greatly appreciated!

I would because as you will find out you can't simply flash twrp as is now. You need an ruu mode version of twrp to flash instead of flashing normally.

If you are "Locked" and "S-OFF", that likely means somebody locked it afterwards to use the fingerprint sensor, since that requires a locked bootloader.
What you need now is to go to the bootloader and execute a couple of specific commands.
I believe the specific thread here has the instructions.
I actually did this once to try the fingerprint sensor. Had to figure out the hard way that "fastboot oem unlock" doesn't work after you S-OFF.
After you unlock, you don't need anything else. You can just flash TWRP normally via fastboot.
