I am pretty sure this has been asked/mentioned before, but to be honest, I really dont feel like looking through/over hundreds of posts and comments trying to get a true solid answer.
My question is, plain and simple. What is/are the major differences between rooting the Galaxy Nexus version 4.0.2 Android and unlocking the bootloader on it ?
I have been searching and so far it looks or sounds like you need to do one before the other, one of them is good for restoring files or something, etc. I have also read that if you are just trying to get the 4.0.4 Android update without having to wait on Verizon stupidity, I can unlock the bootloader, flash the update (or whatever its called) and it will be as if my GNex is rooted, but when I reboot it, it will be stock with all the new stuff that comes with the update, anybody know if this is true or not ?
Unlocking the bootloader just gives you access to the utilities like fastboot that let you root and ROM your device. It removes the "security" that gets in the way of hooking up the phone to a computer and having full control.
Rooting is the process of giving yourself "superuser" (think of it like Administrator) access on the device. Rooting itself doesn't do anything for you, its more about giving apps you install more control of the device.
If you unlock the bootloader to flash an update, you are not rooting your device. You're just flashing a file.
Rooting and unlocking are often confused because on many phones, they're both in the same process and you rarely do one without the other. Usually "rooting" is a catch-all word for modifying your device and changing the software.
Rooting allows you to customize your os. It gives you root access (ie access to everything). To root the nexus you must unlock the bootloader.

I was wondering the same thing, thanks for the answers.

I rooted my nexus without unlocking the boot loader. Via exploit

Other than warranty issues, and possibly redeeming your Google Drive space, are there any practical ramifications to simply leaving the bootloader unlocked (or, conversely, locked?) on an S-off device? I'm inclined to leave it bootloader unlocked unless I have a warranty issue, as it seems the safest way to make sure I'm never locked out, but I'm curious to know if there are any reasons to lock it from a security perspective.
I say that because right now when I lose root due to an OTA, I just boot (but not install) philz touch recovery to re-root, which I am assuming is allowed because I am s-off. (because otherwise root would be trivial). It seems that as long as I can do that, the bootloader lock/unlock state is somewhat pointless.
You are allowed to flash custom ROMs because you have installed a custom recovery, which was allowed because you unlocked your bootloader. I would leave the bootloader unlocked until a relock is required (if it even comes to that). As far as I know, that poses no threat as long as you know what you're flashing on your device. Anyone with more experience with this may correct me, as I am quite new to the HTC world.

I actually only had TWRP installed briefly to "restore" the Dev Edition nandroid (and by briefly, I mean I booted it once). As soon as the Dev Edition ROM was up, I reverted to the stock DE recovery. Since then, I just "boot" Philz CWM to re-root (since TWRP fails when booted on 4.4.3 for some reason.)
Hey all,
so i have (hopefully) read all those "I'm new to HTC"-threads and an almost infinite amount of additional threads all around the internet and especially here on xda in the htc 10 forum. I think i have figured it out so far, coming from a Galaxy S5 it's quite confusing sometimes as there i would have to get my hands on odin, flash twrp and from there on everything is super easy.
CID/MID
The CID of my device (HTC__034) shows me my device is unbranded and the region is europe. This is like the CSC over at samsung where DBT would be an unbranded german device?
The MID is an identifier for the model, it's model specific and should be the same throughout all regions and carriers (read this on some german android wiki site). It's like SM-G900F over at samsung?
Bootloader
The bootloader is locked by default. To be able to install a custom recovery, root, flash custom roms, etc. pp. i need to unlock the bootloader either over at htcdev (where they will store the information about me unlocking the bootloader) or through sunshine which will also S-OFF my device. Once the bootloader is unlocked, no more OTA updates except installing them "by hand"
S-ON/S-OFF
S-OFF is not needed to flash custom roms, but i may be stuck on some firmware version if it won't get updated anymore. To change firmware version i would need to S-OFF my device.
Also, to flash a radio i would need S-OFF. Is this radio you are all talking about what the modem is over at samsung?
S-ON is default, S-OFF is a sunshine exclusive, XTC2Clip won't work here anymore
Custom recovery
unlock bootloader and if wanted, S-OFF, fastboot install twrp
Root
flash supersu, systemless supersu or magisk and systemless phhsuperuser through twrp
Flashing roms
unlocked bootloader and custom recovery needed, then just flash this baby
Nice work, due diligence is rare these days
You got it all very close, your shouldn't have any trouble.
don't worry about S off
create an account at the HTC Dev website
on Dev site, select unlock bootloader and follow step by step
once bootloader is unlocked, "fastboot flash recovery twrp.img"
reboot into recovery and CREATE FULL BACKUP... save it somewhere safe...
at this point you are safe and don't need to worry about bricking your phone!
you are also now done with the computer, from this point on you can switch roms as much as you like with just your phone.
to install rom, save file to your phone, wipe system, dalvik/cache, then install new file, all from within twrp
Let me know if you need any help

Also just to clarify, it is basically the same thing as your s5, but you are replacing Odin with fastboot and adding the one step of unlocking your bootloader first. Don't worry about rooting at first because most custom roms will have it already rooted, so installing the rom will also root... Good luck

First of all, thanks for the answer, just a few more questions^^
S-OFF + unlocked bootloader -> this is what i have on my S5 right now. enabling me to flash and/or **** up everything.
for example take a firmware (bootloader, modem, rom) for s7 and brick my s5 or repartition with a pitfile or whatsoever if i want to
i am able to up-/downgrade firmware from (if it's there) nougat down to marshmallow and back up to nougat
S-ON + unlocked bootloader -> will only give me the possibility to flash new system partition (aka rom), a custom recovery, gain root access and (read about this) flash a kernel. but this won't allow me to update firmware, so as long as i'm on mm, no nougat for me except i relock my bootloader and flash a nougat RUU (check for right MID and CID).
2.1 do i have this right (about the firmware up-/downgrades)?
2.2 the RUUs are basically stock firmware?
S-OFF + locked bootloader
what is up with this configuration? have read it gives me the same options as S-ON and bootloader unlocked?
S-OFF would also allow me to relock bootlader without relocked flag, so it looks as if i never unlocked the bootloader?
AOSP-roms
what configuration do i need to flash aosp roms as soon as there are mor than alpha/beta builds? is S-ON + unlocked bootloader sufficient?

Best way is "S-OFF - LOCKED".
You have the same advantages as with "S-OFF - UNLOCKED", but with "S-OFF - LOCKED" you can go easily back to stock ("S-ON - LOCKED").
You can flash everything AND you can up-/ or downgrade your firmware. So AOSP roms are no problem for you
Never RELOCK your phone.
So the best way is: Unlock your phone with HTC Dev > Flash TWRP > Flash SuperSu > Install sunshine and choose inside the app "S-OFF - LOCKED".
If you want to go back to stock, just flash a RUU.zip and do the s-on command. Thats it.
But, if you still have a firmware version that's compatible with temp root, you don't need to unlock through HTC first. If you're going to spend the Sunshine money anyway, and if your FW version is compatible, go with Sunshine since the beginning.
Also, when you first run TWRP and it asks you if you want to make system writable, say NO. That way, you are able to backup everything untouched and get back to stock in case you want to take OTAs. There are guides that show you how to do it if you decide to stay stock + root/xposed.
Thank you all, so the way would be
download and install sunshine -> done
let sunshine run its tests (temproot etc) -> done and working
(from here on to be done)
pay 25$ and choose S-OFF + LOCKED -> done
fastboot flash recovery twrp.img -> done
i could also do this fastboot boot recovery twrp.img command and then also backup stock recovery? -> no longer available
boot up twrp, no to writable system -> done
nandroid backup (system image, boot) -> done
do what i want, flash custom-rom, aosp-rom, keep stock-rom, flash magisk and systemless phhsuperuser, flash supersu systemless or standard supersu, xposed and whatever makes me hit install in recovery -> done done done
also, never ever RELOCK in case i would S-OFF and UNLOCK
in case i missed something, please enlighten me else i'm of to gain freedom

Okay, I forgot the sunshine temproot. I got my phone from repair last week with latest firmware and it wasn't working. I had to use HTC Dev to unlock first.

After your nandroid backup you have to reboot TWRP and allow writable system, or you can't flash anything a ROM
Not anything. You can still flash Magisk, Systemless Root, Systemless Xposed or a custom kernel. Basically, you can flash anything that doesn't mess with system. A ROM, for example, will need writable system ofc.
Once again, thanks a lot guys, installed twrp which is now asking me for a password. am i right that i have to enter my decrypt password?
EDIT: Just hit cancel worked

I got OTA updates with S-OFF I understand it's the recovery that will block OTA. What I did was S-OFF and HTC DEV unlocked bootloader I have not changed either one since. What I was doing to get latest firmware(for US UNLOCKED or developer edition) was flash a stock pmewl RUU not modify it and take OTAs to get the latest firmware. If you have the m10h in the USA, your LTE is crippled. You may want to convert to TMOUS or US unlocked. LTE will turn on at that point, however you won't get the full AWS spectrum. I use WCDMA(3.5G or HSDPA+) exclusively, unless I'm somewhere it won't work, like southern Denver, even then it's crippled. I quickly came to the conclusion that I need a PME with full AWS spectrum. I did have the device converted to US unlocked and on nougat within hours, nougat at the time was not available for my device out of the box. Another thing I sometimes go into recovery and find if didn't mount data partition. Simply re-flashing encryption compatible TWRP fixes this. Either a backup or image flash from TWRP. Or re-flash TWRP using TWRP app or dd from a terminal.
From my experience, whenever TWRP asks for a password that means data did not mount! The latest TWRP from twrp.me the official one is working fine for me.
The only problems I had were in trying to return to a fully stock condition.
Which is useful to do in case you maybe sell the phone after upgrading or something. And it very much depends on where you got your phone on how successful that attempt will be. For instance, my contract allows me to upgrade every two years, but the CID they use (H3G__001), despite the phone basically being unlocked, is not supported anywhere in the form of RUU. I had to S-OFF in order to be able to change the CID to HTC__001 which is the WWE CID but you can also change a significant amount of other stuff.
The other thing that being S-OFF makes easy is updating or rolling back firmware versions and different revisions of android require different firmwares (for instance between Marshmallow and Nougat)
Although, some of it has the potential to brick your phone, which being S-ON prevents. So it depends just how far you want to go and if you'd rather have that saftey net. But beyond that, you do not need S-OFF to install and run custom roms, or recoveries, etc.
Good points. It is risky to S-OFF, last time I flashed a write value to the safety state of an HTC modem was the Evo 4g, locked to Virgin Mobile when I got it. I had to cut a small section of a wire from an ethernet cable after flashing the unlock binary. Using that cable to ground contact points(at the risk of bricking) I read how to bypass some safety and get into diag mode writing some hex value to something else using fastboot.
I got into Android(and Linux) by hacking the HTC Touch Pro 2 and a laptop to flash it with. That was a Microsoft Phone. Using Haret, and installing Android Donut system/kernel images on the sdcard, you could boot into the Android Linux kernel and everything was loaded. It was slow, no cellular connection, it booted as a proof of concept.
Unpractical for daily use, I just kept Windows with the earliest version of the Sense interface, compulsively flashing every new Energy ROM. Then came the HTC HD2, the last Microsoft Phone(before Windows Mobile), my first practical Android phone. Started off booting Froyo using the same sdcard install and Haret psuedo bootloader method. Dark Forces group eventually formatted the EEPROM of the HD2 using a Linux friendly file system and moved Android from the sdcard to the internal memory. Adopting Linux kernel and vendor sources from the HTC Desire, the XDA community hacked together a fringe device.
I had a few HD2s running Android on a foreign device. Even bricked a couple of them flashing European radios. Only to restore them by buying the same not bricked devices with busted screens on eBay.
You can do things with an HTC, not possible otherwise using other Armel hardware . I mean try writing low level binary states to the modem of an Nexus device, not only to re define the locality of where the device was manufactured to function, but even downgrade firmware versions and the respective security patches.
Won't happen, not without Jtag and a few years of bricking devices while you earn an unrequited masters in computer science, as I imagine the phreakers/developers behind Sunshine must have.
My point, if I have one, is the raw potential before the OP and the device we're taking about.
To even look up a device on XDA demands a degree of user autonomy not encouraged by many manufactures. Like those that resort exclusively to advertising and pandering to made for TV "group think" expectations and attitudes of what a device is capable of. Only what is most profitable to most manufactures will work easily on the device without risk of destruction.
End users intolerant of bloatware and advertising, or limiting personal driving, shopping, usage and locality data to services they chose or at least use and know about. Those are examples of what's outside the stock ROM box.
The communications service industry as a whole will lose profits if they don't buy the majority of these inherently open devices and tailor them to fit, for the most part, their ends. I mean yeah, KNOX is secure, and that's a great cover story to isolate open development. Groups of independent developers, builders, and users can take technology in a direction different and less predictable than what is otherwise a profitable direction.
I like to imagine this fora as a nail in the coffin of computer hardware and software development that unnecessarily limits experimentation and inflates security risks to homogenize those capable individuals under the same or similar payroll. Focusing them on profit over communal benefit, as if we can't have both.
my device is locked & not rooted before
all i'm looking for Is way to root without unlocking the bootloader? I just want root apps, no custom ROMs.
I need to take backup for HTC one M8 before proceed in unlock boot loader , to describe the problem more
the problem is that to take a backup for the whole device , as far as i know i should install custom recovery APP "CWM Recovery , TWRP Recovery ,.........."
which need unlock bootloader in which all data on mobile will be formatted due to unlock bootloader
so is there a solution to backup the current device status to restore them back after unlock the bootloader .
First of all, you posted to the forum section for the M8s variant, not the M8. This is an easy mistake to make, and pretty common. In any case, see my responses below in red font:
Wael-HTC said:

Simple answer, you need to unlock the bootloader to root.
Long answer, some folks have rooted with an app called kingroot. But results are very inconsistent. I've seen a good number of folks who ended up with kingroot unsuccessful, having no root, and also no way to unlock the bootloader! So not a good place to be.
And in any case, in my opinion, any root attempt should be preceded by backing up your data anyway, in case anything goes wrong. So if your intent (in not unlocking the bootloader) is to bypass the data wipe (and skip backing up your data), then we are basically defeating the purpose.
Moral of the story, I would strongly recommend to just bite the bullet, and stick with the "standard" process to unlock the bootloader in order to root.
I need to take backup for HTC one M8 before proceed in unlock boot loader , to describe the problem more
the problem is that to take a backup for the whole device , as far as i know i should install custom recovery APP "CWM Recovery , TWRP Recovery ,.........."
which need unlock bootloader in which all data on mobile will be formatted due to unlock bootloader You are correct, in that you have a "chicken and egg" problem. You can't install custom recovery (TWRP) until you unlock the bootloader. And you can't make a TWRP backup, until you install TWRP.
Side note, CMW never officially supported the M8. There are some unofficial CMW ports for the M8, all very old. Which will almost certainly cause problems. I strongly recommend sticking with latest TWRP for the M8.
so is there a solution to backup the current device status to restore them back after unlock the bootloader .
"Current device status" is a little vague. It depends on what you want to backup:
- For things like contacts, I would suggest just backing up to Google (may already be the case)
- Things like photos, music: use a cloud solution, or simply backup (copy and paste) to your computer
- Stock ROM: You can back this up once you have TWRP installed. There are also stock backup collections, as well as official HTC RUUs for some M8 versions.
- App data: This one is a little tougher. One option is the app "Helium" from the Google Play Store. This is supposed to be able to backup app data, settings, etc. without root. I personally haven't used it (one of the first things I do with a new phone is root, lol). But other folks on XDA seem to have some success with Helium. It is developed by the CWM team.
