[Q] Unlock Bootloader Android 4.2.2

Hey Guys,
i downloaded the nexus 4 toolkit. the latest build (4.2.2) isn´t shown there.
i dunno which version is included in the stock n4. i will get it in a few hours and i just wanted to ask, if my plan is gonna work xD
1. update to the latest version
2. unlock bootloader
3. customrecovery
4. flash rom
the only problem i am facing now, is that i don´t know if the toolkit can unlock the latest bootloader, because "JDQ39" isn´t shown as listed device. or should i unlock the bootloader on a previous version, the stock delivered (i don´t think it will come with 4.2.2) and then install the stock image? as i know from my galaxy nexus the bootloader will be unlocked after that. but i´m not sure how it is with the nexus4.
i hope someone can help me. it might be a noobquestion. i just want to make sure that everything works fast, because this nexus4 is a present for my sister and she´s waiting for it

Normaly it should work, allthough it is not the exact firmware the procedure stays the same. So you should be good.
But between item 3 and 4 comes flashing the superSU zip with CWM/TWRP from here http://download.chainfire.eu/315/SuperSU/UPDATE-SuperSU-v1.25.zip. After reboot you also have to install Busybox from Google play, after that make a nandroid backup in recovery and then flash the rom.

mmh don´t need root in my case, if the recovery will be installed by toolkit, root will be included in the rom anyways

Root is not achieved by flashing a ROM.

It can indeed be achieved that way. If you have an unlocked bootloader and custom recovery then you still might not have root, but you could just flash a pre-rooted custom ROM.

that´s it

Don't use the toolkit, it's easy to do manually. That way you will learn more about the steps involved, which will come in very handy if you have a problem with the phone in the future.

Tnx but didnt find answer there sir, i mean if there is a new upate like 4.3 or 5.0 is it possible to update it officially or not? I am rooted and unlock bootloader w/o CWM
If i were to flash it,is it ok to flash it directly after flashing a custom recovery?
Sorry for many question. Im a sony Ericsson user before thats why im confused with a different method.

Best way is to flash the full new rom (4.3 probably) in fastboot, reroot, restore apps with Titanium Backup and you`re done. Flashing a full rom is better than updating an excisting one imo. Link for how to flash stock rom http://forum.xda-developers.com/showthread.php?t=2010312.

Yes, it is not hard. Just follow instructions and you should be good
Fastboot:
- Power down the phone, then
- Press Volume down + Power button
That`s it

You can be on stock with no mods unlocked rooted with a custom recovery and you will get the ota update and it will install fine.
The ota update link will be posted here before you get on your device so it's good to have a custom recovery so you can just flash it and it will also protect you from losing root or custom recovery

Correct mate although this http://forum.xda-developers.com/showthread.php?t=2584938 is much easier, but its really good to know the manual method too. Most important thing is to MAKE A BACKUP in twrp before wiping. You'll thank yourself later on. The most common question on this site is ... 'How do I restore stock?' Anyway, have fun!

Rooting from within 23.5.A.0.570 Marhsmallow discussion

Anyone know of a way to root 23.5.A.0.570 from within the ROM?
Of course you can create custom firmware with Flashtool, but is there other way?
Kingroot is useless at the moment.

Hi,
I've upgraded from Lollipop to MM yesterday, but with TFT rom, without root.
Then: http://forum.xda-developers.com/xperia-z2/development/kernel-advanced-stock-kernel-t3347413
But only works with unlocked bootloader.
I've just unlocked my bootloader and installed this kernel using ADB. But, FULL WIPE in my Z2 :'(
Don't know if was the kernel or just the fact to unlocked the bootloader.
Anyway, make a full backup

Its because of the Bootloader u unlocked.. Unlocking bootloader first time will erase ur all datas..
And there is no need to unlock ur bootloader. Simply go back to KK or LP then root it and install recovery. After that flash a pre rooted MM rom.. Simple
And i think after unlocking bootloader u have lost some Sony features.. Did u make ur TA (DRM) Key backup..??

Why do people think it's too difficult to downgrade to another version of Android, root and install a rooted android mm zip thought recovery?

Are you using Xposed? because after many re-flashes and reinstalls on different things, I think, that for me, few of the xposed mods were causing the loops. For example I miss the immersive mods in games etc and I simply can't get it to work correctly as it was, no matter what I try, so different xposed mods related mostly to that were causing the loops for me. I am currently reflashing at the moment

Oh crap, I knew it, but in the Sony developer's website doesn't show this information...
About DRM, I know I have the backup, but I don't know where, lol. Anyway, in the same topic, there's a procedure to recover the features.
tks for explanations!

So u want to root ur MM right?
Well u can simply downgrade and root it along with recovery. Then backup ur drm key using TA Backup tool from xda. After that u can flash a pre rooted MM rom

HELP with rooting

Hello. I'm new to Android and all of this rooting and stuff but I want to try out flashing a custom ROM but I don't know how. Do you need to be rooted? I know about custom recoveries and stuff but I need to know exactly how.
EDIT: My model number is WAS-LO3T
My build number is WAS-LO3TC654B198
EDIT 2: I watched the One Click Root video. Is it safe? Is kingroot safe?

ANYONE? pls

How to root link below (includes unlocking the bootloader). Follow the steps very carefully as this is your first time rooting. I am not to blame nor anyone here on xda if you end up with a bricked phone. If you use android pay this will no longer work, some bank apps will not work either FYI due to root.
At present there is only one custom rom available however this is not specifically made for our device but for the p8 lite. When I flashed it about a month ago there are some bugs still like camera not working. Hopefully some talented people will buy our device and develope a custom rom for us.
