Question about returning my N4 to Google - Nexus 4 Q&A, Help & Troubleshooting

Just began the RMA process with Google Play by ordering the replacement device. Now when I send back my faulty unit when the replacement arrives, in what state should I leave the software of the phone so that the RMA process finishes smoothly?
I'd imagine I'd have to flash stock rom+kernel, stock recovery, relock the boot loader, unroot, and possibly reset the flash counter (have no idea how to go about this last one). Anything I'm missing/feedback?
This is my first time going through Google's RMA process and I want it to happen as smoothly as possible. Thank you.

Nexus phones dont have flash counters. All you need to do is flash the stock images and relock the bootloader.

I've never heard about a flash counter on a nexus

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 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
Sent from my Nexus 7 using xda app-developers app
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!).

Don't flash anything from another device.
Read the instructions carefully to install/flash a rom or kernel.

+1 That`s about the only thing to brick a Nexus
Don't do any formatting, and don't delete partitions. If you need a clean slate, do a factory reset or flash the stock image using fastboot.

The only thing you can't format is the bootloader that will brick it
Sent from my Nexus 4
Yep avoid flashing stuff for other devices. Most things will be recoverable but some can brick it. E.g. recoveries
Never ever use the command fastboot erase bootloader as this will 100% be a brick
I haven't seen anyone do it on the nexus 4 however i have seen people do it on the nexus 7

Bought a Nexus 4, but am worried now.

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).

Will Google accept return with custom ROM installed

I have pacmanrom installed on my device.
The issue is my headphone socket not software related.
So, will they accept a return or do I have to do some resetting process?

It's always safer to return to stock, if doing warranty stuff. Just do a nandroid backup, return phone to stock, send to Google and when you get it back, just restore your backup.

I'd use this toolkit, it's pretty easy to use:
http://forum.xda-developers.com/showpost.php?p=44984820&postcount=1951
or you can download stock image manually and flash it with fastboot, then lock your bootloader.

Flash a Nexus 4 factory image from Google: https://developers.google.com/android/nexus/images#occam
It will overwrite the bootloader, recovery, and /system, therefore wiping the device of any customizations.
Don't forget to also relock your bootloader at the end: fastboot oem lock

Question on returning to stock

Hello wonderful XDA Peoples. I am planning on returning my Nexus 4 in the near future as part of T-Mobile Jump. I'm currently on a stock ROM; but unlocked with CWM recovery installed.
To return to stock, would I need to fastboot the entire stalk image (via flash all.bat) or would I just need to flash the stock recovery image, then relock the boot loader? Thanks guys! Keep up the absolutely spectacular work.

You could just flash the recovery.img and then re-lock it

on the nexus 4 rom,kernel .... index there is a stock recovery flasher, if you dont wanna use the pc
if you have root you can lock bootloader via an app
or else just via pc.
