[Q] [HELP] Can't re lock nexus 4 bootloader! - Nexus 4 Q&A, Help & Troubleshooting

I have my first android device, the nexus 4, and I rooted it. I used the Nexus toolkit, being new to android and rooting and all. I now need to send my phone back to Google and I can't relock the bootloader! I managed to unroot it but now I just need to relock it and get rid of the padlock. I have tried everything that I have found online and nothing has worked!
I am really becoming annoyed with this! Can anyone help please?!
Thanks, LJ.

It should be an easy thing to do from fastboot. I think the command is something like fastboot oem lock. The toolkit should be able to do this action also. Once that command is complete then reboot fastboot and it should be completed.

That is exactly the command.
fastboot oem lock

Being "new to android and rooting and all" is the biggest reason not to use a toolkit. You just press a button, have no to little idea what exactly happens to your phone and then go "pls my phone doesnt work and is eating my cat pls help" when something goes wrong...
Sure, everything seems easier when you use a toolkit, but you end up having no idea what to do when the toolkit fails
Just sayin'.

this.
and for any nexus device, rooting the right way is just as easy if not easier than a toolkit. the only difference is that youll need to read up a little, get familiar. im mean how easy is this to root..
1. fastboot oem unlock
2. fastboot flash a custom recovery
3. flash either the su binaries or a custom rom
4. reboot and profit.
then to lock the bootloader just fastboot oem lock.
thats all that is needed for any nexus.

I have been using a nexus as well. Download nexus toolkit v2.0 it does it all. I flashed half a dozen ROMs and unrooted and relocked bootloader and re rooted it
Download it and enjoy

Are you getting any commands to work when you are in fastboot? Like fastboot reboot or flashing a recovery img? I'm just wondering if you have fastboot setup correctly. If you can do those other commands, relocking shouldn't be an issue.

I have also followed efrans guide, step by step, and was typing all commands into the command prompt. The phone was responding too. When I booted it up, I was stock rom again but the boot loader would not lock. Strange! :/

Follow that guide but instead of entering the first command for returning to stock now just type in "fastboot oem lock"

Trickster Mod has an option to Lock/UnLock your Bootloader as long as you are rooted and you use a kernel which supports such extravagances. (i.e.Franco-r210, for example)

I'd recommend getting familiar to fastboot would be the best option, too. If it's not working, what is the exact error or is there none?
You could try this app to lock it, too, if the phone is still rooted

There's no one click method I know of for the Nexus S.
What do you mean you can't root & it won't budge? This phone is about as easy they come (without some one click app): http://forum.xda-developers.com/showthread.php?t=931865
Install the android sdk on your computer.
Put the su.zip file on your sdcard partition of the phone.
Put the phone in fastboot mode.
Fastboot flash the recovery.
Select recovery.
Select install zip from sdcard.
Flash it.
Reboot.
You're done.
If your computer doesn't recognize the phone while it's in the bootloader, you gotta install the google Nexus S drivers or the one from PDAnet. That was where I got stuck at 1st when I tried rooting. Fastboot couldn't find my phone because I had the generic windows drivers.
Also if you have PDANet on, turn it off before putting your phone in fastboot mode.
Actually there is a one click method...brb with it
http://www.theandroidsoul.com/easy-one-click-root-for-nexus-s-full-guide/
Or search superboot nexus s
Here on xda
Either will work PC or mac.

Interesting. So the steps on the referenced one-click method you posted are:
1) put your phone in fastboot
2) do the fastboot oem unlock command manually.
3) run a batch file that contains two lines (fastboot-windows.exe flash boot boot.superboot.img & fastboot-windows.exe reboot).
I guess that's easier than putting your phone in fastboot directly and typing in a command to flash clockwork, then selecting a zip file to install from clockwork, but not much.
The drawbacks here are of course that it's superboot, and that it requires you to unlock the bootloader. I guess it's useful if you're really noob, but it only saves you typing one command.
The noob part is very true. However I prefer my bootloader unlocked anyhow.

You do not need an unlocked bootloader (currently) to use custom roms, or to root, or to flash clockwork recovery, etc...

Of course, but since you contradicted my statement earlier that one disadvantage to the posted method here was that it had you unlock the bootloader by replying that you like having yours unlocked, I was trying to pin down if there was an advantage to unlocking the bootloader that had been discovered that I hadn't heard yet.
There's indication on git for our phone that the next update includes a change to the bootloader being able to use the fastboot boot command while locked. Unknown what that will actually do in terms of just fastboot flashing clockwork to apply root and custom roms.
I c wut u did there. I'm not sure how the update is going to affect things ATM. I keep it unlocked for "in case sh*t" happens. Never know what an update will bring in changes to rom management.

Nexus 7 Boot Looping

Hey everyone, I joined xda to see if someone could help me with my problem. So recently I rooted my nexus 7 using wugfresh's root toolkit. I then installed aokp after i tried out paranoidandroid......i flashed gapps each time. I then wanted the old tv style screen off animation and using that toolkit, so i extracted the framework-res.apk ...........and i don't know what went wrong. Now all i can do is boot into the bootloader. When i try to go to recovery, it shows an open android with a caution sign in it. it just keeps bootlooping the aokp animation. I can't find any solution....help! i just want to go completely stock and lock the bootloader. it wont work with wug's toolkit.
Are you plugged in to your PC using the USB cable?
Yeah. Using the OEM cable from Asus. It charges and everything.....what do I do? I'm stuck and stressing about it.

Don't worry we will help you get it figured out. It's very fixable, mostly take some deep breaths and destress. When you start to panic then you have more of a chance of messing something up.
What happens when you use the command adb reboot recovery? what's the message you get? I'm guessing if you're extracting framework you're real familiar with ADB but if not use the toolkit.
Did ADB work before on your same computer you're on?

reflash your recovery via fastboot, not with a toolkit. then reflash your rom/gapps. if its still a no go, wipe then reflash your rom/gapps.

The message I get is error: device not found when I use the adb reboot recovery. And I'm not familiar with it at all. I was trying to get that TV off animation and I was following a guide. This is my first root. So far....not a good experience.

This is about the 15th post I've seen this week about someone screwing up their n7. If there already isn't one there needs to be a step by step video for the correct way to unlock, root, and flash Roms. I suggest others read heavily before doing any flashing. Its bad enough the boot loader is already screwy.
The toolkit does everything for you. All in one method and you're done.

I had this problem happen with my Xoom.
Boot into the bootloader from recovery. There should be an option to do so.
In the bootloader flash a different recovery.
Then reinstall your ROM. It should boot.
If that doesn't work I would suggest flashing the stock images in fastboot and starting over.

I had a similar problem on my og evo. Try seeing if you can flash the recovery from a computer while booted into cwm. Then it'll reboot into new recovery, you flash rom, and you stop sharding your pants

Hmmm. You should have a working adb while booted into a custom recovery. Are your drivers installed correctly?
Also, the reason why you computer sees the files is because with mtp it caches the files.

Sorry I wasn't trying to bust your stones. I haven't rooted yet because of all of the posts like yours. I've just seen more problems with flashing on this device then any other that I have with my past Droid devices. What we really need is apx (spelling?) Drivers and n7 files for a sure fire recovery from any disaster
Hopefully I don't have to start another thread.
I too think I bricked my Nexus 7.
I was having trouble and I accidentally cleared a file from the System UI app (its a system required app) which caused me to loose the 3 buttons on the bitten of the screen.
So I went to CWM to do a restore which said it failed.
After that it would not boot.
Its just stuck with the Google logo on the screen.
I held down the power up & down volume buttons and I get a screen that gives me that START button on the top right of the screen with the text in small size on the bottom left.
I can use the up and down volume to make the start button change to recovery mode or bootloader but activating them just goes to Google logo.
Can I recover or is it totally lost?
I also don't remember if I left the Nexus 7 in Debug mode which is usually required to perform custom Roms
Thanks

[Q] Which rooting method?

I see a couple of different tools here to unlock and root my Nexus 7. What are the differences between them?
I do not want to flash ROMs; just unlock, root and install cwm recovery.

then you should br helping out all the people that mess up their devices afyer using toolkits and dont know how to fix it. i havent seen you help out, yet you are still recommending toolkits. why is that?
I used the steps outlined at http://rootzwiki.com/topic/28544-guide-nexus-7-bootloadersrecoveriesrootback-to-stock/ to guide me.
I must say it might not be trivial for the non-software-developer types.
I was a Java developer for many years, so I didn't have much problems setting up Java,
Android-sdk, etc.
My N7 was recognized by adb when booted normally, but after I flashed cwm, I could not do 'adb shell' to mount the /system partition and rename the recovery-from-boot.p file to prevent the recovery from getting reset to stock each time.
I ended up installing the ROM Manager app to enable me to boot into cwm recovery.
I have done the obligatory cwm backup. I believe this is the nandroid backup?
Edit:
I used my Linux box to re-flash the bootloader and cwm recovery images to the Nexus 7, and I could 'adb shell' and rename the recovery-from-boot.p file. So I'm all set now.
I just needed to run 'adb start-server' and 'fastboot' using sudo, so it might have been a permissions issue on my Windows box.

Looks like I'm not all set, after all Today, right before I plan to take the JB 4.1.2 OTA update, I notice my tablet won't boot into CWM, like it did a couple of days ago. I did rename the one file and things looked normal. What could have happened to my CWM?
Edit:
So there are 2 files that need to be renamed, not 1?
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
And there was a bug in JB 4.1.1 that prevented booting into cwm recovery unless the device was plugged into USB??

In the early days, automatic transmissions were more problematic and much more expensive. Today they are pretty efficient, even though a manual transmission gives you better control over the car, which most people don't really need for everyday driving.
If you frequently get stuck in stop-and-go traffic, you'll wish you had an automatic transmission.
Look at these lazy people..

Yes there was a bootloader bug on the nexus 7 and most people could not boot into CWM recovery without plugging it into their computer.
I however used TWRP back then [have since switched back to CWM touch, now that the bug is fixed] and had no issues. Now I have no issues with CWM touch, I can boot it directly from fastboot menu, or "reboot -> recovery" when booted.

Yeah, that's what I'm saying. They both have their ups and downs. If you're willing to learn a little about how Android works and learn some adb and fast boot commands then you should definitely do it manually.
If you just want to be a "1337 Haxorz" and aren't willing to learn then just use a toolkit.
OK, just one sub-question on rooting. I see no real reason to root except maybe to get more tablet interface than nexus has. Kinda like when the wifi indicator is at the bottom, since there are those !$#$$ back/home buttons already and a lot of wasted space Anyways, the question.
I bougth N7 16Gb and upgraded via forced OTA to 4.1.2. Do all these root methods work with 4.1.2?
Thanx,

[q] help please!!!!!

when i was unlocking my nexus 4, the reboot process was taking far too long and a friend told me to restart so i held down the power button to restart it. After i did that, it would either bootloop on the colors or just stay on 'Google' screen! I have access TWRP but i can't fastflash anything! and when i look around TWRP, it says i have no OS installed! TWRP allowes the option to ADB but im not sure if it's properly installed. Please help!!!!

Google 15 second adb install xda. That'll setup fastboot on your pc. Then flash the factory image in fastboot
