(Q)bootloader and rooting

hi to every one i would like to ask before i unlock my bootloader and rooting stuff. im presently on stock rom right now with firmware 2.3.4 baseband ver. -64 and build number .62. i alredy browse threads and guides about this but unfortunately i was not able to find answer.
ok my question is this.
1. will it be possible for me to install custom rom if im just going to unlock my bootloader but not rooted?
2. there are topics about easy rooting on gen. discussion .i just like to ask,is it possible to disregard downgrading process from .62 to .42 if the bootloader is unlocked for the rooting process. since i dont want to downgrade.there has been issues of bricking the phone if your going to downgrade and update afterwards via ota.
3. can anyone give me updated guide for unlocking bootloader and rooting based on my current firmware.
Thanks in advance.

Yes, custom roms are usually (always?) prerooted, so it gives u root permissions. Bootloader is needed to flash custom kernel.

If the bootloader is unlocked ur phone gets bricked after update. However u can downgrade with locked bootloader, next root and than update. If u want lock bootloader use file attached (unpack rar archive and flash ftf using flashtool).
On the other hand u can install CWM and use RootXperia.zip (attached) to root.

Bootloader:
Unlocking
Root:
1. 2.3.3 - use SuperOneClick Method (maybe work with 2.3.4 i dont use it) or RootXperia.zip or custom Kernel/Rom
2. 2.3.4 - use RootXperia.zip or Custom Kernel/Rom

YOU DON'T HAVE TO UNLOCK BOOTLOADER TO ROOT.
Download flashtools. Install on computer
Download ftf from general stickies( select. .42/.54) only these can be rooted
Drag and drop ftf into flashtools main screen
Put phone into flash mode(hold back key while plugging into usb port) flashtools will install Rom
Restart phone.
from settings select usb debugging( development) and unknown sources( security)
Download from doomlords thread for rooting gb file
Keep phone switched. On and connected to computer run the script and follow on screen prompts.
When done phone should be rooted.
IF BOOTLOADER IS LOCKED YOU CAN UPDATE OVER THE AIR.
ONLY DO THIS if 100% SURE BOOTLOADER IS LOCKED this will update to 2.3.4 build. 69 latest stock from Sony.

Why not unlock bootloader, flash custom kernel with root support, root and delete bloatware (or what you now are going to do) then flash stock kernel, relock bootloader and voila - everything fixed?

So much work...
And I wish it would include links.
I really hope there will be a one-click root for 4.4.
It's weird all phones from the competition are easily rootable but someone 4.3 on Sony is so complex.

They've closed alot of the bugs that were being used for the previous root methods.
IF you don't care about your data, what you CAN do is to revert to an older FTF, root, backup your TA partition, then go from there... it's a pain... but it works.

So I saw this and was about to do it, but then read this post:

Seems much easier (no bootloader unlocking necessary) so I'm trying to figure out why you'd have to do everything listed in the other thread. Any insight?

if u want your phone to be stuck in bootloop, go ahead with that method, else you follow the method which i posted. it's a long procedure, but it works!

I don't understand why someone would post bad directions like that. Also they are very similar to Doomlord's own instructions for rooting. He says to flash an old exploitable kernel and then run his exploit and then flash back.
Anyways, your method says to downgrade to .67 firmware, and I can't find that anywhere. Can I downgrade to .423 firmware and use Doomlord's root method instead? Should be the same results, right?
Also, is step 8 necessary? Do I have to flash back stock recovery or can I keep CWM?
And finally, using this method, how will we keep root when 4.4 finally arrives?

Thanks, It worked without any problem.

I also wouldn't take the risk to flash the Kernel of .423 over the .67 firmware.
Yes they are both Android JB 4.2. But you never know.
About 4.4, we will have to wait what will be the available methods.

yeah. that kernel method worked for previous firmware. now it won't work. and yeah you can downgrade to any rootable firmware. u are doing this just to backup TA so that you can lock BL. you can keep that advanced kernel. but you wont get OTA updates, better to flash stock kernel and lock your BL. when 4.4 arrives, if no rooting kit is available, you've to unlock BL, install advanced stock kernel which has custom recovery and install SU and flash back stock kernel and lock your BL

After you've rooted, but before you actually unlock your bootloader... if you install the dual boot recovery, you can make a backup of your TA partition information via TWRP as well as by using the other method... (do both to ensure you can revert)...
And then after you unlock your boot loader save ANOTHER TA backup... name them so you know which is which so you can re-lock your TA if you choose if you're running a stock kernel/rom and want the DRM keys back... but that way you don't have to go through the pain for unlocking each time...

Well I ended up not even needing to unlock the bootloader for my goal, which was simply stock + root on .101.
http://forum.xda-developers.com/showpost.php?p=52411661&postcount=23
Only had one small issue with the flashed zip/stripped FTF messing up the XZDualRecovery settings, but deleting xzdr.prop and rebooting fixed it.

When i was searching for, i really thought i was being crazy.
so many devices with a single click to root
I cant wait to start theming my ZL, Some mockups cooking here to new skins, but can't test without that root.
well, Did that steps worked well?

if u go with method, u have to download those stripped files every time when new firmware arrives. which is kinda boring to download those huge files. whereas in that unlocking BL method, u download only kernels with recovery which is just 15 to 20MB

[Q] Doubts in rooting

So far I've had only Samsung phones, which were rooted by flashing a zip file through the built-in recovery (containing signed SuperSU).
Now I have a 2013 Nexus 7 and I'm looking at the rooting guides and I see bootloader unlocking, flashing custom recoveries and a lot of other things which personally confuse the hell out of me as to why are they needed.
So I wanted to ask if there is a way to just flash a zip file with the SuperSU (and buzybox) app like how it's done on the Samsung phones? Or if there is a method that doesn't require replacing the stock recovery / flashing ROM components?

If anything its easier than any Samsung device but the thing is don't Root if it confuses you at least until you understand how to do it there is tons of guides online

That's kind'a my question, it's not that I don't know how, I just don't get if all the side-stuff in 90% of the guides is actually needed, so I asked if there is a way to just get SuperSU working without any custom-recoveries or other side-things.

To my knowledge, you need to have a custom recovery to root it. Unlocking the bootloader helps with this, as it ensures recovery and root sticks.

Or, just use the Wugfresh Nexus Root Toolkit to unlock and root.

I was in the exact same position as you four days ago, up until then the only android devices I had owned were the Samsung Galaxy S2 and S4. It is quite different to the rooting process on the samsung devices but just as you did with the Samsung devices you will learn as you go along. My bootloader is unlocked, rooted with a custom rom and it was pretty easy to do

A sideload would only be needed if you didn't dump SuperSU on the phone first.
Unlock bootloader
Flash TWRP
Flash SuperSU
Done

Get wugfresh's nexus root toolkit. It's made for the novice in all of us.... Works great, self updates, awesome help section.. Look into it.. It's made specifically for the nexus line of products

Thanks for the replies guys, but noone seems to say what is the minimum that neds to be done for rooting.
I'll re-ask my question in a different way:
When rooting, does the bootloader always have to be unlocked and a custom recovery always needed to be installed?

Bootloader needs to be be unlocked, but can be relocked after rooting
AFAIK, you can use stock recovery, but custom offers better options/control over the situation. Most roms/kernels are flashed via twrp or cwm..... You can flash through rom toolbox if you choose to stay stock recovery

You can use Towel root to root your tablet in about 30 seconds. It'll also unlock your bootloader for you.
Cousin recovery is only needed of you intend to flash kernels and Roms and the like. If, like me, you only want root for installing things like xposed then you don't need to bother with one.

Yes, all the steps that are listed are required for rooting your Nexus. I understand what you are asking and I was also hesitant at first, but it was super easy to root and I didnt use the WugFresh took kit I manually rooted mine, following Zedomaxs Video tutorial, that way I could stop and Pause it at every step to make sure things were happening as they should here is the link
https://www.youtube.com/watch?v=X1cD-JXRGX8

I confirm towelroot works on the 2013 nexus 7. After rooting unlock bootloader with app from google play. This method does not wipe user data or need a computer at all. And if root is lost and the towelroot exploit is patched with the next os update you can reroot the old way.

How to RE-lock bootloader of oneplus3???

Any one knows how to re-lock the bootloader of one plus 3???
And
How to remove that screen on boot up after unlocking one plus three??? :/

If you read the screen properly ull see the instructions on the screen itself do everything the same way you unlock the bootloader just instead of oem bootloader unlock type oem bootloader lock ...but make sure you're on stock rom and recovery

But then My root access will be wiped??
I want root access and dont want than annoying screen

two questions different answer but I would bet if there is a way to remove nag screen a google search would find it. Keep searching threads

there is no reason to re-lock bootloader, its still under warranty through Oneplus even with unlocked bootloader. but if u really want to
1. fastboot flash stock recovery (fastboot flash recovery recovery.img) (make sure u download the file, its somewhere here on the forums
2. reboot and then reboot to fastboot (fastboot oem lock) (i have never re locked a bootloader so i am not sure if it will rewipe ur device again like unlocking it does)
3. boot to OS and get developer options again and uncheck OEM Unlock (do this last)
i would not recommend re locking since it wont void warranty and seemed like a lot people screwed up their devices relocking it, but they also unchecked the oem unlock before flashing stock recovery, also i am not sure if step 2 is needed, i would just make sure u flash stock recovery 1st before doing anything

HELP
I try to relock the bootloader but in this momento my oneplus 3 is blocked...I cant update with the stock rom...please some help!!! :crying:

What part of be on stock OS is so hard to understand?
If you're not absolutely stock when relocking, you will brick your device.
Then good luck trying to enable OEM Unlocking when not being able to boot.
As someone who messes with their phone, relocking your bootloader is one of the worst possible things you can do.
If not done correctly, it WILL brick your device.
If you want to go back to stock, then surely do, there is absolutely no need to relock your boot loader unless you're selling your device to someone or if you're looking to pass SafetyNet for Android Pay or something.
Also, you cannot have the cake as well as eat it. You need to have an unlocked boot loader for root, exposed, etc. There is no way around this.
Phones previously had to be reverse engineered and exploited to gain root access, now OEMs freely allow unlocking.

I hope you can read this. I'm not a noob and I am looking to relock my bootloader because I am going to sell it. The person wants it fully stock so I need to relock the bootloader in order to regain access to official Ota updates.
I need to be on complete stock (stock recovery and rom) right? Would you please kindly point me to where I need to go to download the stock Rom and recovery. There's some TWRP flashable OTA zips on Oneplus forums that restore stock Rom and recovery but I want to be sure that that is enough and that I don't end up bricking my device for something as stupid as this. Any help would greatly be appreciated!

Fash 3.2.4 FW from here.
Follow all instructions from here (except I would suggest sideloading the StockROM before relocking).

I followed the same guide posted on OnePlus Forum to re-lock my bootloader. Just follow them, it works.
Here is that link from OnePlus forum.
1. I restored my stock rom backup from TWRP
2. Flashed Stock recovery
3. fastboot oem lock
4. Sideload stock ROM
Done.
I unlocked because stock ROM I felt was much stabler and hassle free. Have rooted and played with custom ROMs enough in my Nexus 5 days. Just too much stress and can end up with non-working features. Might root again in future if I find something compelling in custom ROM.

If you unlock device, you will still be able to apply OTA. If you rooted by modifying the /system partition, OTA will fail, but if thou rooted using systemless method, you can apply OTA.

Iam on stock OOS 4.0.3 and i was plagued by the same error
--adb sideload the complete rom (with locked bootloader)-- method worked for me.
Previously i had unlocked bootloader and was on freedom OOS 2.3 with TWRP and then i realized that stock updates are better.
So i installed stock recovery and and tried to flash Stock Firmware 4.0.3 through sideload command and it failed.
then i installed TWRP and then installed stock OOS 4.0.3 and it installed fine but with some error.
Then i installed stock recovery
So i rebooted it and after long time it was installed but then i started getting dm_verity error and also i was frustated with unlocked bootloader message.
So i locked my boot loader first from fastboot oem lock and then sideloaded the stock 4.0.3 again and it really worked.
So now i am on stock rom and stock recovery and no more dm_verity error or unlocked bootloader msg to wait for 5 secs...
Now iam really loving my Oneplus 3..
