Hi I'm new around here but to unlocking and rooting. In the past have had multiple android phones or a which I have put custom Roms on.
When unlocking the bootloader on the Nexus 4 it say it wipes your data what exactly does it wipe?
Is it just my apps and the setting or is it everything ie music pictures videos apps settings.
Thanks in advance for anyone that can awnser my question

Does it acctually remove or overwrite the data so it can't be accessed no matter what or does it just delete and leave it so someone that knows how could retrieve the data?
nope it wipes everything like if u was gonna resell it nothing exist after that procedure so make a backup of what u need cause its gonna get formatted
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 do not know for sure but I quite doubt it.
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.

Doesn't this void the warranty though? I know it did when i rooted my phone.

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.

How do you save your stock image?

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!).

I'm thinking about selling the phone and wanted to wipe everything. Can someone tell me a way if its possible without the touch screen being responsive.

Erm, yes, it's possible but it depends where you can get to. If you can get it into fastboot then you can reflash the stock rom and relock the bootloader.
That'll format the internal partition and obviously make it look OEM. That said, you not thinking of fixing/RMA'ing?
unlocking the bootloader will wipe everything. then relock it.

I just purchased a Nexus 4 and upon checking out the device I noticed the model number says Full JellyBean on Mako. What does this mean?

Mako is the code name given for the nexus 4 device. Jelly Bean is an Android release.
Mine said: Nexus 4. Did you buy it new or used. If used and you're worried, just flash the factory stock 4.3 image which will erase everything previously.

Most likely a custom rom. It doesn't look like the kernel is stock kernel to me. It's safest to do a full wipe and factory reset. You should update to 4.3 anyway, use this guide:

I wasn't able to update to 4.3, and my computer wasn't recognizing the phone either. However, after booting the phone into bootloader, my computer recognized it. So I unlocked it and am currently flash stock 4.3 onto it via Nexus Toolkit.
Hopefully it works out for you. However, try not to use toolkits in the future. If something goes wrong at some point you won't know what to do if you rely on toolkits. Learn the manual method of flashing.

I know how to manually flash and all that. It's just I already had Toolkit installed and just thought it would be quicker.

Yeah, just enable USB debugging and it should recognize. If USB debugging doesn't work (it should), try installing drivers again (manually).
Don't forget to hit "thanks"
Hi. I recently deleted and formatted everything even lost all my recoveries and back ups and am trying to put nexus 4 stock rom back on to my device. What do I do? I still have clockworkrecovery mod but that's it and a computer to work with.
Download the factory images of your choice and flash them. It is the 15th time today that I am telling this to some one.
Sent from my Nexus 4 using xda app-developers app
I've just done this and used Nexus Root Toolkit, absolute god send. Just plug your phone in, as long as you can get to fastboot, then flash stock + unroot and in a short amount of time you should be back to good.

ok that's what I was doing but I was going to try to install zip from sideload cause I don't even know how to get to my sd card and the android 4.3 stock rom I was downloading earlier was taking hours and my computer got shut off so that never completed.
Flash rom with adb. You will be fine
