CWM with locked bootloader? - Nexus 4 Q&A, Help & Troubleshooting

Hey guys,
I just bought the nexus 4 from a guy and its working awesome. The only "problem" I have is that the guy before me was playing around with the nexus. And now I have a locked bootloader, no SU binaries/root but CWM?? Is it possible to have CWM with a locked bootloader?
Anyways, i dont want to play around with it because the original store that sold this nexus will blame me for playing around with it if something actually happens.
So can i update it to key lime pie when it comes out without any problems?? Or can i remove CWM without unlocking the bootloader(i have alot of apps)?
Thanks

You can flash a ROM and then relock the bootloader. Just unlock it and start again

Nevermind

It's better to go back to 100% stock so you know exactly what's been done

You can always use this if you're rooted. https://play.google.com/store/apps/details?id=net.segv11.bootunlocker

Why would you want to relock?
Just unlock, root and be done with it.

Unlocked and rooted now. Just made the regular backup through rooting toolkit and voila and everything back to as it was after restore. Didn't take too LNG either for backup or restore.

@krelvinaz
as unlocking bootloader is not necessary for me (i dont flash new roms , ...etc )
also you know that feeling you are doing something wrong took me awhile (lack of courage) to root
@ghostaa
noob question , did the backup restores everything (even the widgets you placed on your home screens, i hate to customize it again)
Nope backup didn't restore the widgets but apart from it everything else was!
Hope this would help...

you need to unlock the bootloader to install custom roms etc. I'm sure you could root the device install a su binary and super user and then easily relock the bootloader with a single command fastboot oem lock. What exactly are you afraid of? It's super easy if you have android sdk installed.
I don't wanna void warranty... and I don't want the related factory reset.

You can backup everything using adb backup (okay there are some app you can't backup with that, e.g. Temple run or Subway Surf) and after unlocking restore the backup

Downgrade to 4.1.2 possible for nonrooted ?

Hi everyone I was just wondering if its possible to downgrade my nexus from 4.2.1 to 4.1.2 if I'm not rooted. I'm currently not interested in rooting my device so is there a way to do it without rooting/unlocking?

I can't flash things because I'm unrooted. So I don't think this method will work. Correct me if I'm wrong.

I am curious as to why you want to though. Not that there's anything wrong with wanting to downgrade, of course.
Have you tried one the took kits available? Check around in the Nexus 7 original development section. Look for Wuggs.

I looked at his toolkit but it basically says that I have to root in order to even use the toolkit so is there a way to downgrade without having to go through that rooting process? For now, I don't want to root my nexus

Don't try to root it you'll only manage unlocking the boot loader then when you try and root it it will get stuck in fast boot mode I tried about every rooting program but it could be because my Comp is running windows xp lol

It's so easy to just reflash stock and relock the bootloader that you really have nothing to worry about. If you want unrooted stock 4.1.2 just unlock the bootloader, then flash the stock image of 4.1.2, then relock the bootloader after. It's a really simple process.

If i'm not mistaken, as long as you flash back to 4.2.1(which is the os it came with when u got it out of the box), and then re-lock the bootloader, unroot, then your warranty wont be voided mate. hope I helped.

Yeah, I've done this plenty of times with my Nexus 7 and even the Verizon Galaxy Nexus. As long as you're on a stock image with a locked bootloader, they won't give you any trouble or claim you voided your warranty, as there's really no way to tell. I've gotten into the habit of unlocking and rooting my device as soon as I get it, and if I find a problem I just revert back to a stock image, relock the bootloader, then send it back in. I have yet to have a single issue.

You don't need to worry about saving your stock image. The person above you is talking about saving the stock image to return to after flashing a custom ROM.
There is no way to revert back to 4.1.2 without root access. Doing a factory reset, about the only thing you can do without root, will only return you back to stock 4.2.1
My advice just stay on 4.2.1 whatever your issue is with it.
Otherwise use a toolkit. You will need a PC and the 4.1.2 image. Wugfresh has a website. I would start there.

I actually was just referring to the stock images you can get directly from Google or from goo.im. It's easy enough to just use the 4.2.1 stock image from Google to just restore back to how it shipped, and then relock the bootloader.

Completely agree with this... I have, on several occasions, reflashed stock, switching between 4.1.2 and 4.2.1 - (for me, it was more of an exercise in learning about fastboot and adb... and making sure I had TRIED AND TESTED factory images on my laptop as contingencies should anything go wrong when I came to start flashing custom ROMs).
-----
You don't need root to flash a factory image... everything is done with fastboot; with the Nexus 7 in FASTBOOT/BOOTLOADER mode (from complete shutdown, press and hold Volume Down button... whilst holding, press the Power Button).
(Root is meaningless anyway, here in FASTBOOT/BOOTLOADER mode, since /dev/block/mmcblk0p3, the SYSTEM partition, hasn't even been mounted yet - so no SU binary available... whether or not it exists, it's sort of irrelevant).
- here, for example, is the flash-all script from 4.1.2 (nakasi-jzo54k)... (Nexus 7, WiFi model only).
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.41.img
fastboot reboot bootloader
sleep 10
fastboot -w update image-nakasi-jzo54k.zip
After running this script (flash-all.bat if in Windows, or flash-all.sh if an Apple user) you can optionally choose to lock the bootloader with... (if you're concerned about warranty issues).
Code:
fastboot oem lock
-----
If it was the case you needed root to run...
Code:
fastboot flash [partition to be flashed] [IMG file to flash]
...you wouldn't be able to flash a CUSTOM RECOVERY like CWM or TWRP... and thus, you wouldn't be able to flash Chainfire's UPDATE-SuperSU-v1.00.zip (http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip) in order to gain root in the first place!... (you see the paradox!).

Root nexus 4 without unlocking bootloader

Hi all,
I used to be a hard core iOS user and just boarded on android wagon with my nexus 4 version 4.2.1. I am still learning my ways around android coolness and stumbled upon apps like display control for nexus 4 or titanium backup etc which require root access.
Can I just root and install these apps or any other apps which needs root access without unlocking the boatloader (From what I have heard it will wipe phone and is only useful if there is a need to install custom roms...which I have no use for as of now..just root)
Thanks in advance.
Sent from my Nexus 4 using xda app-developers app
I'm pretty sure you need to unlock bootloader to root..
I recently rooted and was able to back up everything.. I dont think I lost anything when I restored my backup
You only need to unlock the boot loader if you are going to flash custom ROMs. Other you can leave it locked and just root it.
Sent from my Nexus 4 using xda app-developers app
The short answer is that you must unlock.
The long answer is that in theory you could achieve root without unlocking but in practice any other method is just too difficult.
No one is going to make the effort when backing up all your files, unlocking, then starting again with an empty phone, is about a million times easier.

Use a new app called carbon backup. No need for root. It backs up app data etc...

Titanium requires root
Read this if you want to have root with a locked bootloader.
But you still have to unlock and lock

I was under the same situation, but part of learning is breaking stuff.
I had to reinstall the stock rom in my phone twice in the first week, and lost all my settings in the process, I would just say that rooting is worth the process and the pain.
And carbon backup does not require root
I have unlocked and rooted my Nexus 7, and I plan to do the same with my Nexus 4, so I'll go ahead and ask the question here.
Once I unlock and root, could I, and should I relock the bootloader, and if so, will it wipe all data again, but leave it rooted? In other words, I want to root, but have heard that leaving the bootloader unlocked is a bad idea. If the response applies to both my 4 and 7, please advise.

Bootloader unlocked may void warranty.
Unlock bootloader. Root phone. Relock bootloader.
But when u install an OTA u have to do the same process again because
u lose root.

If I unlocked, rooted, but didn't relock, will relocking wipe my tablet/phone again?

Thanks to all folks for taking the time to contribute here.
OK..so what I am hearing is that I can unlock the boot loader for root but that's not mandatory. Correct? Is not t advisable ?
Also will I lose ota updates if I
1) just root, no unlocking boot loader
2) root + unlocking boot loader
Again I have no idea on androids world of custom Roms and kernels

You need to unlock bootloader to root. I don't believe there's an exploit for rooting with a locked bootloader for jellybean.
You won't lose ota if you unlock and/or root. Just make sure the phone is only rooted and no system files are modified

You need to unlock the bootloader if you want to root. But you can side load apps (Not using Play Store) without rooting.
Unless the app requires root for the app to function correctly.
Thanks so much guys. I went ahead and unlocked the boatloader followed by root. I used the wugfresh toolkit and it was a cakewalk. I didnt install any custom recovery.
The only problem is dolphin browser beta has stopped working now. It was great before.
Also, should I re lock the boot loader...and how.

Nexus 7 blocked in bootloader

Hi, I just upgraded my nexus 7 to android 4.3 and then I have unlocked the bootloader with a tool for Ubuntu users. Then, I install a recovery, and then I root it but it doesn't work. So I decided to downgrade to 4.2.2 with the tool with "flash Google factory image" but an error occurred and the nexus doesn't boot
I can just go in the bootloader, I have the bootloader unlocked, but no recovery, and no root.
Here is my question : how can I install for example cyanogen 10.1.2 but blocked in the bootloader ?
Don't forget that I have just Ubuntu.
Thanks.

If your bootloader is corrupted you can't boot anything. You're going to have to find a way to get your bootloader flashed. I don't know much about this but on my S3 I used Odin.
