I'm currently rooted and have twrp on my opo. With bootunlocker you can unlock/lock your bootloader from withing android without wiping the device, whats interesting is if I relock my bootloader with the app I can still install zips from within twrp, I thought locked bootloaders prevented this? Or am I wrong lol thanks if anyone can put my mind at rest ?

If my memory serves me right, you can't flash ROMs and if your phone gets bricked with bootloader locked, it will be a brick.

Hey
I unlocked the boatloader, which wiped the phone, and rooted it when I first got it.
I got the new update recently and just found out I lost root. Is there a way to get root back without wiping the phone? I still have the unlocked bootloader since I have the little lock on the boot screen.
I read the guides, but they all seem to also do the fastboot thing that unlocks the bootloader or installs a new ROM. I just want to keep my phone the way it is (stock) and root it. I'm just really confused about how to do it.
Thanks!
Mount USB while in Android
Copy su.zip
Boot into cwm recovery
Install su.zip from sdcard
Done

I don't have unlocked anything. I'd like a rooted phone without having to wipe anything. Is it possible?
If the bootloader isn't unlocked then doing so will wipe.
If it's unlocked installing su and recovery as I described will wipe nothing.

Ok. And I suppose you cannot root a phone without unlocking the bootloader first?

i rooted my s3, then i unlocked the bootloader. i still havent flashed anything but now when i reboot my phone i get the custom notification with the unlocked padlock. did i do something wrong or is this normal.
edit: i used a windows based program to root and i used twrp to flash the unlocked bootloader
I am waiting on a stable completely functioning rom before flashing.

Sounds like it's not unlocked if you still have the custom boot screen. What method did you use to unlock?
You are not unlocked. When your bootloader is unlocked that Samsung screen just flies by. No padlock no waiting.

Thanks! i used a windows batch file to do the unlock...guess ill give it another go.
worked thanks!
My SGiii now does this when booting. I have root. I used the devFS root method. I to my knowledge I have not flashed the boot loader. Is this what people were talking about by adding one to there flash counter? If so I might as well flash cwm.
Is my warranty void now?

Has nothing to do with flash counter. It shows that software is modified and is caused by root. Unlocking the bootloader will get rid of lock. Warranty is void only if you don't revert to stock before return.
I have unlocked and rooted my phone. I am proud of the fact that it is mine. I know to most people it isn't an issue, and it isn't THAT big of a deal, but i would like it to go away anyway...
Is there a way to hide the Lock Icon you get after unlocking the bootloader in the Boot sequence?
Yes. Re lock the bootloader with the "bootlocker" app

I'd prefer to recommend bootlocker. Once you have root access, you can lock / unlock /reset tamper flag at will without connecting to a pc.

You sure its not Boot"UN"locker? I've never heard of an app that did this so, out of curiosity, I searched for "bootlocker" and found "bootunlocker" instead.

Is relocking it going to cause an issue if I decide to install a rom in the future? Or use Wugfresh to lock and unroot? Or will it be seamless?

You can still flash roms via recovery with a locked bootloader. You just need to unlock the bootloader again to update your recovery.
DON'T EVER USE TOOLKITS

Just to update recovery I will need to relock the bootloader?
And out of curiosity, why not use Toolkits? If its to help me gain experience, I usually have no problem using adb, but I'm at work and figured it was easier. That, and I am lazy

No. You'd need to unlock the bootloader to update recovery.
Its easy enough without toolkits. Being lazy and taking shortcuts is dangerous.
adb isn't really related to anything we're discussing here

Good morning!
So, yesterday evening I rooted my N5 with Towelroot, installed TWRP and then flashed the latest SuperSU! Everything went fine and now I want to install PA (4.4 RC1). But I'm not quite sure if I need to unlock the bootloader for that... I think that only needs to be done for a kernel. So what should I do? Leave it locked and flash PA, or unlock it and flash PA?
Also, if someone could set me up with the 4.4.3 gapps, that would be nice. I downloaded a file, but its not a mini version and only has 97MB. The full versions are a lot bigger if I remember correctly, aren't they?
Anyway thanks!
*edit: I'm currently on the 4.4.3 stock ROM. That means that I don't need to update my radio, because it should already be the latest version from the OTA... Correct me if In wrong though!

Please can you ensure you ask questions in the questions section ?
The bootloader only needs to be unlocked to flash recovery which you need for rooting. This isn't an issue for you because you used the new exploit that means you can root without having to unlock the bootloader
Even though you've rooted already, I strongly urge you to read the pre root section in the thread shown in my signature to bump up your basic knowledge

I do have basic knowledge (rooted my Nexus Phones before, every time with fastboot). I'm just asking if it is important to unlock the hootloader before flashing a ROM, as I'm not sure. Sorry for posting in the false section...

You can install custom ROMs, but only ROMs based on stock firmware and using stock kernel. ROMs like CyanogenMod, you can't install at all because you cannot flash the custom kernel that comes with it. Unlocked bootloader allows you to install unsigned kernels onto your phone.

Isn't that the case, or have I been misinformed? I left my boot loader unlocked since the day I was rooted, mostly because of that fact (I remembered reading it somewhere) and also because I can't do a RMA.

You unlock the bootloader to flash a custom recovery. You flash kernels/ROMs in a custom recovery, not in bootloader.
Also this thread is in the wrong section.
So, if I just unlock my bootloader with bootunlock I won't have any problems?

That was where I was getting at, since I learnt to root using the manual way and not using a toolkit, I had to unlock my bootloader first before flashing a custom recovery. Never occurred to me to relock it.
(if I made a mistake somewhere, I apologized. I'm still learning, and learnt something new today!)

You can flash a kernel/ROM in a custom recovery regardless bootloader state, but the bootloader needs to be unlocked to use fastboot (i.e. flash the custom recovery in the first place). A bunch of people relock their bootloader with an app (and unlock when necessary, doesn't delete internal storage through this method) for extra security (internal storage wipes if bootloader is unlocked via fastboot).
Is there any tool that will reinstall the stock rom on a Nexus 5 with LOCKED bootloader? Something like emergency reflash from LG Support Tool.
LG Support Tool? There's something LG Flashtool and that works.

If you have to reinstall the stock firmware why do you care? Just unlock the bootloader, you're going to lose everything anyway.

The ideea is that I want to root this phone with Towelroot and I've heard that if Google detects a change in the system you can't install any more OTA updates. If this is true, I want to find a method to reflash the stock so I cand get the updates.

If you're rooted but otherwise completely stock, you should get OTA updates no problem.

Well if you modify any system files you don't get the ota. Your best bet is to root and then flash a custom recovery with flashify and then flash a stock rom zip that will be created shortly after any updates come out. You can also unlock the bootloader without wiping data with boot unlocker after your rooted.

There's a whole sticky on returning to stock so you can get OTAs. </thread>
If you're able to flash the stock ROM, you should be past the point where you need to worry about being able to get any updates.
Yeah. I'd highly recommend just flashing a prerooted busybox stock ROM. You can always do a dirty flash over stock ROM and still keep data.

You do get the OTA, but if you modify /system/ or something else, the OTA won't install.
It takes 10 minutes to return to stock for an OTA. Just do what you want with the phone now and enjoy!
The next OTA will be months from now. Return to stock then.
You dont need any tool. Download factory image and flash that by executing flash-all.bat (for windows, if you use linux execute flash-all.sh). Flash a custom recovery. Then remove hidden tampered flag by flashing tampered flag remover zip. Then flash stock recovery and lock bootloader by typing fastboot oem lock.

Locking the bootloader isn't enough on its own.
Android: adb pull data, MTP (Screen lock can prevent)
Custom recovery: adb pull data, flash zip to turn off android lock screen (Recovery lock can prevent)
Lock bootloader: Prevent replacing locked recovery with unlocked recovery,
