I have unlocked my boot loader which doesn't allow you to use recovery mode. Is there a way to completely wipe the phone and undo the bootloader thing? What program can you use. Also, how can you hide the bootloader unlocked start up screen? Thanks

I want to be sure you have all your ideas straight. How comfortable are you with working from the bootloader or from recovery? What tools do you use? Can you access recovery by this method?: Hold "Power" and "Volume Down" for ten seconds and release. This takes you to the bootloader. Then press "Volume Down" once to select the recovery, then press "Volume Up" to activate that option. This should then boot into the recovery. If that is not what happens, let us know what happens instead.

There should be no problem using any of the various recovery modes with an unlocked bootloader. Stock, TWRP, and CWM should all work fine. Can you describe what you did, what happened, and what you expected to happen?

There are several things here. You can wipe the phone and return it to factory defaults by using "fastboot -w". This does not change your bootloader or recovery. You can re-lock you bootloader, but it will always register that the bootloader was once unlocked. There is no real benefit to relocking the bootloader so I won't put instructions here, but let me know if that's what you want to do. Finally, you can flash a new recovery image onto your device, which will wipe out whatever recovery image you had on there. The command looks like "fastboot flash recovery recovery.img".

This is simple as flashing a new logo. The command is "fastboot flash logo logo.bin". This will overwrite the stock logo (which checks if the phone is unlocked) with a modified one which looks the same whether it is unlocked or not.

I mean fastboot recovery thing if that's what you didnt think.

I can get into the recovery screen fine. Selecting recovery puts me into a no command screen and then just boots up as normally. I was expecting to get another menu with factory reset and cache reset, and factory just boots up normally. Is factory reset from the fastboot screen just the same as the reset in the settings menu? Is it that you cant use those settings with a unlocked bootloader.

Are TWRP and CWN both apps you get for/through rooting in which you can restore back up etc? I have heard about CWN but havent really used it.

Would doing "fastboot -w" just do the same as reset from settings menu? Also I'm not sure what you mean by flash a new recovery image?

Also, I dont understand how to remove the boot loader unlocked screen. You have to start a command prompt and type in that with your phone in fastboot mode?

Is recovery

Sorry for being such stupid noob pleb

I think I understand the problem. The first screen you come to says "Fastboot flash mode" or something like that and has a boot mode selection menu with "Recovery" as one option. This screen is the bootloader. When you are in the bootloader, you use the fastboot command on the computer to do things to the phone.

When you select and activate the "Recovery" option, you get a screen that says "No Command". This is actually the stock recovery. TWRP is TeamWin Recovery Project and CWM is Clockwork Mod. They're both roughly the same in terms to capabilities. Both have far more features than the stock recovery. You can use adb to communicate with your phone in recovery mode.

Here is a program that will help you install the recovery. USB debugging should be turned on on your phone, and you should be booted into the system. Also be sure that the proper USB drivers are installed on your computer.

Here is the latest version of TWRP. You should download this image and use the above application to flash it.

As always, ready everything carefully.

Why you need relock bootloader ?

Use philz recovery based on last cwm. It's amazing.

Here is a thread about removing the warning screen: http://forum.xda-developers.com/show....php?t=2548530
In summary, you can either download "logo.zip" and install it from recovery, or you can download "original_logo.zip", extract "logo.bin" and use "fastboot flash logo logo.bin" when you are booted into the bootloader. I am assuming you do not have a "Google Play Edition" or "GPE". If you do, there is a different logo for you in that thread.

The bootloader can be relocked, but it will not change the warning screen. Locking the bootloader will only make it so you cannot flash custom recoveries and such. Can you explain what you hope to achieve by relocking the phone? Again, it can be done, but I want to make sure it is really what you want.

You can't go wrong with either TWRP or PhilZ. PhilZ is based on CWM. It has added features and touch capabilities. Because a recovery is so easy to switch, if you make your best guess for which you will like more, and if you are not happy with it, you can switch. I like both, and most users will find all the features they need in either one.
TWRP looks like this: https://www.xda-developers.com/wp-co...13/11/AgsV.png
It can be downloaded here: http://forum.xda-developers.com/show....php?t=2561757
PhilZ can be downloaded here: http://forum.xda-developers.com/show....php?t=2639583
Its features and screenshots are here: http://forum.xda-developers.com/show....php?t=2201860
