Keep in mind that I'm not an expert on the custom side of android. I've only so far managed to flash cyanogen and root my device
Here are my questions:
Is every samsung phone's bootloader unlockable? I was locked into the stock rom on my xperia because - "Bootloader unlock allowed: no".
Is there any sort of mechanism preventing me from unlocking the bootloader on the s4 mini, like on my xperia M?
Will "knox/eFuse" (what's the difference?) brick my phone if i try to flash something?
I've already went into download mode and knox wasn't tripped, says 0x0.
Thanks for reading

Most samsung devices don't require unlocked bootloaders , you can directly flash roms after you root the device and put a custom recovery ( TWRP/CWM )
Tripping knox/efuse it only voids warranty

I need your help guys,
just got my Xperia ARC and i wanted to root it by this guide and i have a few questions:
i bought the phone from an Israeli carrier (pelephone if its matter) so in the guide i need to change the carrier firmware to the original firmware and i wander if it will void the warranty. also is there any way to change back the firmware after the change, if so then how? i searched and i couldn't find anything...
thanks ahead
The thing with Rooting a phone, is that you can root your phone and still the ¨stock¨ Arc is untouched after you have unrooted.
The flashing and rooting dont break the warranty by it self.
If you change from locked bootloader to unlocked.. The warranty is removed.
Easiest way to root is:
*Download*
3.0.A.2.181 Generic World: http://www.mediafire.com/?y9s73andrl4bllc
*Use Flashtool to Flash .181*
Flashtool: http://www.multiupload.com/7H4JT35B6G
*Use Gingerbreak after you flashed back*
http://forum.xda-developers.com/show....php?t=1044765
*After it have rebooted and active, go to settings and do a OTA over wireless.
This way you keep your Arc locked, nothing good comes from unlocking the bootloader yet.

That's not entirely true. You've got custom ROMs being developed; over-clock kernel just released, Recovery and what not.
Unlocking the bootloader is personal choice. I may not unlock my bootloader just yet but I can't deny that with improvements being shown, it's an increasingly tempting option. LOL!
Well It looks as if I Cant remove unnecessary apps on my Arc without rooting.
But here is something i wanted to ask before I go ahead with doing That
Q1) Is it necessary to Unlock My Boot Loader for Rooting or Rooting can occur without Unlocking it aswell?
I mean that I have read rooting without unlocking it but will it be the same locked or unlocked?
Q2)Unlocking My Boot loader means a 100% surety that my warranty will be Nulled right? (I Live in India, Rules don't differ here or in UK does it?)
Q3) If I have Rooted and NOT Unlocked my Boot Loader, Can I still update my Phone software through SE PC Companion? And Is my Warranty Still Safe?
Because I read that ICS will be available for Arc in the first quarter next year so I want to update my phone using SE PCC and NOT by flashing even though I know the pro's of flashing
Thank You so Much!

1. No you dont have to unlock BL to root your arc search for doomlords easy rooting toolkit
2. As far as I know yes
3. Yes you can still update with SE PC companion but I think updating via PC companion removes root. And your waranty is safe
You can use zegrush to root without unlocking bootloader. I live in India too. U can still update after rooting but not after unlocking. Rules apply everywhere.
Xperia Arc (rooted)
Thank you sooooo Much!!!
One more question
@Tatit1011- in reply to ur question 1, are dere any pros/cons of rooting after unlocking BL and. Rooting without unlocking it??
Sent from my LT15i using XDA App
If you unlock your bootloader you CAN: flash custom roms, kernels(for overclock), and generally anything.
You CAN'T: upgrade via se, either pc or ota via the phone. Plus drm is lost, as is your warranty, but you can re-lock it
Generally, if all you want to do is remove system apps and use apps like titanium backup, root explorer etc then just root. If you want to try custom roms(there's only one you can flash over stock kernel, I think) then unlock the bootloader.

Just a question im hoping someone can help me with
I have an S4 mini, I-9197 with std firmware, 4.2.2
build is I9197XXUBML3 which has knox and locked bootloader
I would like to get root on this device to run a particular app, but according to CF website
"UNLOCK BOOTLOADERS If you have locked bootloaders, flashing one of these will probably brick your device"
So has anyone sucessfully got root on this model phone and software or is it not possible due to locked bootloader and potentially bricking it,
Im not concerned with KNOX warranty status as i dont use any apps that need it, just need root access.

Try Towelroot
https://towelroot.com/
download, install and that should do the magic.
have tried towelroot but phone just reboots therefore is unsucessful
I guess that that phone is completely locked from modification.
what for mod options are available at a R800i with a locked bootloader.
i have tryed to open it with flashtool but without success
official unlock is not possible i know
i would like switch to CM but without open bootloader - no chance.
which alternative products would be possisble
sorry for my bad english
Try unlocking the bootloader with the testpoint method: http://forum.xda-developers.com/showthread.php?t=2187172
Xperia Play test points: http://i.imgur.com/bY6qdBh.jpg
I have "Bootloader unlocke Status: No" as well, but this method worked for me. But since it won't have fastboot, you will need to flash custom kernels via Flashtool: http://forum.xda-developers.com/showthread.php?t=2739559
But if that doesn't work, then get yourself rooted and install this app: https://play.google.com/store/apps/details?id=com.pvy.CWMinstaler&hl=en
This will install a custom recovery which will allow you to flash ROMs that allow locked bootloader.
so wait, to unlock the bootloader on an R800at you have to take the phone apart??? (thought it would be like on an HTC Evo V when I had to short 2 contacts with a paperclip, the contacts were exposed when you removed the battery cover....
Dear XDA Community,
I have an Xperia M C1905 and I have checked the service info menu and it shows "Rooting Status: Bootloader unlock allowed:Yes" so I can unlock bootloader but I have heard that unlocking bootloader can cause the phone to bootloop. So I want to know how to unlock the bootloader, root this phone and add a custom recovery. I don't know whether I should take a TA Partition backup or not. I do own an xperia SP which I have but it is broken so the Xperia M C1905 will have to be used for the time being. Can someone from the forum show me the right links for unlocking bootloader, root, custom recovery. A set of instructions to follow since looking at the forum I got no idea which guide to follow for this phone.
Currently this phone requires the bootloader to be unlocked without causing a bootloop to happen.
It is currently running android 4.3 stock - Build Number: 15.4.A.1.9
I'm a noob at this since the last time I unlocked bootloader and added custom rom to the xperia SP was like 4 years ago.
Thread closed on OP's request.
Regards
Vatsal.
