What would be the difference between these 2 methods of rooting for XPERIA Arc?
I know Gingerbreak is much easier to do than the other one. But, is there any limitations to what Gingerbreak can do compared with the other method ?
Since bootloader is still in locked state, that means those who did it with Gingerbreak still have their warranty valid, right? What about the installation of future custom ROM ? Would the devices rooted with Gingerbreak have no chance to install custom ROM because the bootloader is locked ?
Sorry, I'm pretty much confused atm about rooting the Arc.
My understanding is unlocking the bootloader does not give you root. Even those with unlocked bootloaders must root using either ginger break or the other method.
Having the bootloader unlocked will allow for installing custom roms though, when recovery is sorted. Those of us with locked bootloaders will have to hope for a workaround at a later date.
As for warranties...who knows on this one. SE have allowed the unlocking of bootloaders saying it "may" void warranty. Theres nothing to say rooting will void it. Personally I think the only way you will void it is if you brick it whilst fiddling with it. I think any hardware issues will be sorted regardless. (but thats my opinion, dont take it as gospel)
Rooting is rooting, it doesn't really matter what the mechanics of it are, if it's successful then the outcome is the same.
As for the two methods, yes, GingerBreak seems to be the simplest so for most people there's really no reason not to do that. If it fails and you have a handset you can unlock the bootloader on, then you can always do it the other way if need be.
When it comes to custom ROMs, there's a good chance that having an unlocked bootloader will be a requirement, to begin with at least.
It's possible that someone will find a way to offer custom ROMs for locked bootloaders but it's just more work.
if the buutloader remains unlocked your phone can ALWAYS be repaired through seus, the bootloader needs to be unlocked for the phone to be bricked . also flashing of custom roms may not require the bootloader to be unlocked - as is the case with the x10. as far as i know though the bootloader needs to be unlocked to flash new kernals but there is a workaround that for the time being with the ability to flash the various basebands. my bootloader will remain locked for the timebeing - its a sure failsafe if anything goes wrong
Thanks for the replies everyone.
I had this concept of "If you don't root your phone, you can't install custom ROM" and "If your bootloader is locked, you can't install custom ROM" before I found this Gingerbreak rooting method. (i.e. boot loader unlock -> can root -> can install custom ROM)
But just before it was conflicting because with Gingerbreak root your phone, but it seemed to me that you can't install custom ROM because the bootloader is locked. However they said "If you root your phone you can install custom ROM".
So for this time being, taking out the question whether custom ROM (which no one yet to make it for Arc) can be installed, I think it's safe to say : "Gingerbreak rooting with busybox installed gives you the same capabilities to bootloader unlocking + fastboot flashing", right?
more or less......
x10 was never unlocked bootloader，how many custom ROM out there？

Not exactly. You can't flash custom .imgs via fastboot if you don't unlock the bootloader.
And I don't understand why people think that phone can be totally bricked if you unlock the bootloader...
sorry to say that，unlock bootloader seems waste of wait of time，if gingerbreak works

Well... yes, I already thrown that factor out when I asked my question.
But looking at the history, is there any case a custom ROM can be installed on a phone with bootloader still in locked state?
This is AFAIK
SE uses locked bootloaders for three reasons
1- A secure place to put DRM certificates.
2- A secure place to SIM lock the phone
3- A secure way to forbid modifying the software, as the bootloader will require a signed software in order for it to boot it ( If I'm not mistaken this is the problem with X10 unlockable bootloader as it's just hard to sign an image, correct me if I'm wrong ). the signed software thing is meant to be for not bringing bad software that may damage the phone
After SE saw that a lot of peoples want to install custom ROM's into their phones without too much hassle and a lot of them understand the risks of this so they decided to make it possible to unlock the bootloader but they want it to be the right way...
1- First the DRM certificates will be deleted as installing custom ROM's with exposed DRM certificates can bring serious legal problems to SE ( as this will mean the ability to save a digital unprotected copy of a DRM protected media )
2- SIM locked phones are excluded from this bootloader unlocking as this can make it easy to unlock the SIM lock so this will put SE in a bad position between operators..
3- As the main reason for unlocking the bootloader is installing custom ROM's and this is what the community want's SE made a bold statement here that doing so will violate the warranty as SE can't guarantee what a custom ROM may do to the phone...
but x10 has recovery

The Arc isn't the X10.
Boring. This is a first time i use SE phone. I think this is also a last time. I will come back with HTC. There are no custom and no one with cook custom rom for SE device already

I think you're just a little patience
From what I gather, they can't refuse a warantee repair if it is a hardware fault, not caused by the unlocked software (as it is a problem with their manufacturing, and therefore their fault), but if you mess your phone up with something due to the unlocked bootloader they can (for example, you overheat your CPU with an overclock or something).

That's what I heard too. As long as you didn't mess with you phone in some way, they can't prove that the hardware fault came from the modified software and should therefore repair your phone nonetheless. I guess that's why they say that unlocking the bootloader MAY void one's warranty.
have rooted thro' gingerbreak - but am am getting frequent random reboots. while calling or recieving. can anyone help me with this.
For work I have to use mobileiron, which detects everything from root to the unlocked bootloader. I am not sure if it simply detects the unlocked bootloader or detects because of the warning that comes up, I would guess its the latter.
So not only can't I root, I can't unlock my bootloader in the current state. At the very least I would like to enable wifi tether, and I would do that through TWRP but then I can't unlock my bootloader. So way to relock without wiping.
So I guess the question is for people who don't know about MobileIron is will we be able to unlock the bootloader without setting off any other options? or is there way to at least edit build.prop without root or unlocked bootloader?
I guess ideally if I could root without unlocking the bootloader then unroot that would solve my problems. Thoughts anyone?
Here is a thought, although it might fail. You could unlock your bootloader, boot TWRP without flashing(fastboot boot twrp-rgvrg.img), make your changes, then boot back into the bootloader and relock it.
Still can't say for sure it would work and it will virtually guarantee your userdata be wiped.
Buy a second phone for work related purposes
I'd never spend so much on a phone just to let my company lock it down
You could always test out various configs and see what trips the software or not. You might be able to keep TWRP and root just turned off via supersu and everything work. Similar to android pay. You might not even be able to unlock the bootloader. Anything in between in possible.
Regardless it is pretty trivial to go back to stock and get everything locked back up again. So there is little risk in trying.
If it were me I'd try root and see if it worked. No? Ok, try to disable root with supersu. Will work or not. If not then make your host file edits for adaway and such and then completely remove root. See if that works.
You can also try to unlock the bootloader now as stock and see if it impacts the software. See exactly where it trips and prevents you from using it. Then work from there.
If nothing works, go back to 100% stock and lock the bootloader again. At least you gave it a go and had some fun for the evening. If I had to guess something in between will work and you can work around the limitations.
I'm getting a 6p for Christmas and I have a question.
Say the 6p is on Marshmallow, and I decide to unlock the bootloader (just that, no root or anything) on MM. Will I be able to update to 7.1.1 via ota (no I don't want to sideload or flash) without issues? Or is there a process to it like updating bootloader, vendor, radio or whatever else. Or does the Ota file contain the updated boot.img and vendor etc.

Yes, you can unlock then update via OTA. OTAs patch every partition permitted there are no modifications done to system and boot.

Why would you want to unlock the bootloader if you don't intend to root or install a custom recovery? I don't understand what the benefit is.

@ricbaez
No disrespect, but I would say why would you NOT unlock the bootloader on a Nexus? Especially when you first get the phone because unlocking wipes it. Unlocking the bootloader allows you to use MANY more tools in the event your phone boot loops or becomes unresponsive. There are dozens of threads where people are completely screwed because they did NOT unlock the bootloader and so cannot salvage their device with ADB/Fastboot. If you bought a Nexus, one of the selling points is that Google ALLOWS the owner to unlock the bootloader right in the Dev Options! Even if the OP is not going to root or install a custom recovery, if he/she does not unlock the bootloader, they are going to be S.O.L. if the phone won't boot. There are many examples of this since Google has gone to the monthly security OTA's and updates. Or... simply put, if you are unlocked you can flash full Google images and use ADB/Fastboot. If you are locked, you can only sideload an OTA with the stock recovery and that hasn't been working out well for so many people here on XDA.
To the OP. Recommend you unlock your bootloader first thing which will wipe the phone and start you out fresh. Unlocking the bootloader will not prevent you from receiving OTA's. Make sure your Google login works properly. Login. Logout. Login. Then do whatever the F you want with your phone, knowing you will have serious options to recover in the event things go south for any reason. Next would be installing TWRP. Good luck!

You are right. I wasn't aware that people were having boot loop issues on phones running stock Android but that apparently is the case. But as long as USB Debugging and Allow OEM Unlock are ticked in the developer options you should be able to unlock the bootloader later through ADB if you need to. I assumed the warning about my phone being insecure since my bootloader is unlocked that pops up every time I boot was there for a reason. There is no security issue created by unlocking your bootloader?

It's cool, and I respect your decision to stay locked if you decide that is best for you. I suppose you could set Allow OEM unlock in Dev settings AND USB debugging in USB just in case, but if for some reason you could not boot, unlocking bootloader would then wipe userdata and your backups would be gone before you could transfer them off. In the end it's up to the individual to choose security vs, recoverability. Many ppl are getting locked out of their phones in the interest of security (or just the default settings). As it turns out, they were just trying to perform a monthly security update and hosed their phone. Stock rom, stock recovery, unrooted. Every Nexus phone I've owned (Galaxy?) has been unlocked so that I could use all the tools available to get myself out of a bind if needed. I don't give a sh!t about the boot up warning, because I know that my nandroid and FF backups can get me back home in the event of a lockup. Unlocking will not stop you from receiving OTA's if you are stock. Even if you are not, unlocking will allow you to use ADB, custom recoveries, toolkits, etc. If you end up in a bootloop and your bootloader is locked you are S.O.L. plain and simple. Each to their own though... if you need encryption and value high security of your data over recoverability then you may want to stay bootloader locked. As owners of a Nexus phone we have that option. Many others do not. Cheers my friend!
Thank you guys everything was successful, unlocked it in no time, downloaded 7.1.1 and it's perfect. NOw time to flash twrp and MegaPixel Rom
I'm making a barely educated guess here, but my understanding is that the 905V and 900V (Note 3) are very similar so it occurred to me to try the Note 3 bootloader unlock on the 905V after getting my hopes up regarding [ROM][P905][UNOFFICIAL] LineageOS 14.1 then installing TWRP on my rooted 905V running NK1/4.4.2 only to realize that the bootloader was locked and I couldn't run TWRP.
My CID did change and has stayed modified after using that tool and rebooting, but I still cannot run TWRP. This means that the CID change was good, but the bootloader is still locked right? Is this idea fundamentally flawed, or do we just need a different CID for the 905V and a modified "unlock_n3" could get the job done?
I'm reaching out to ryanbg and beaups to see if they can help or provide feedback.

That is specific for the N900V bootloader. It will not work with this device. You're lucky you didn't brick your tablet. The unlock doesn't work for this device.
I've been combing the forums for a couple of weeks trying to get information about upgrading my old note 4 (Verizon, MarshMellow). I wanted to use the Lineage OS 18.1 but I can't find a way to unlock the bootloader. I've tried every method without success. None of the temp root programs seem to work. Odin gets close and then fails at the end. Same for ADB. I can't seem to get a clear answer to a question: Do you have to downgrade to 5.11 before attempting any of this? If so, how is that done on this phone? It is alluded to but not clearly stated anywhere. I'm willing to do the legwork, I just need a clear starting point.
Thanks
To unlock a device's bootloader it's NOT required device's Android is got rooted.
To flash a custom ROM like LOS you have to find a suitable custom Recovery for your device and flash this as 1st thing of all things.
Thanks for the response. That's what has been confusing. Most of the procedures I've read (some of them older) state the the first step is to temp root with Kingroot or similar. These don't work on my phone so I haven't gotten very far. Others want you to unlock the bootloader first. Same problem, can't find a way to to that in this phone that works. I'm pretty OCD so I'll keep searching.

If you are using an SM-910 with a locked bootloader, like the 910V, then the answer is an unequivocal YES you must first unlock the bootloader before you can accomplish anything substantive with it, and to do that YES you must also downgrade to 5.1.1 to root it and unlock the bootloader. And your device must have a CID 15 eMMC chip to achieve any of this.
