Hello,
I'm new to all this so forgive me my noobish questions. I've allready searched the internet for tutorials and how-to's but nothing seems to work.
Can someone help me on how to unlock the bootloader?
I would like to install a custom rom but need to root the phone first, in order to do that it has to be unlocked ...
Iv'e tried with adb & fastboot but nothing seems to work.
The phone (samsung S3 GT-I9300 android 4.3) remains locked.
Thanks in advance for your help

I think it's locked ... if i try with adb & fastboot ... (several commands to check if the phone is locked i don't get an answer) ... only <waiting for device> message.
Is there any other way to check if it's locked?
I'm afraid that if i try to install TWRP it will block the phone and all i have left is a useless paper weight.

The bootloader is not locked. Samsung phones don't have a fastboot mode, they have a download mode. You have two options for flashing twrp: odin or heimdall.

Hello,
I installed Odin307 and downloaded CF-root-sgs3-v6.4.tar, after connecting odin to my S3 and selecting the CF root file ... after the phone rebooted and went back to android i got the message "PASS" in odin.
So if i am correct, the phone should be rooted by now.
Now i guess: installing TWRP via odin and the google apps ... what version of Lineage Os would you recommend?
If i check on the website of lineage os, the samsung s3 i9300 is no longer available ...

Hiya
I've desided to change my rom on my G925F and I have it rooted however I am unable to reboot into the bootloader I can't find any way to unlock it.
Any thoughts, hints, ideas that would help me in my quest to rid my phone of bloatware would be greatly appreciated
You won't need to unlock your bootloader if you have a 925F - do you mean you can't boot into recovery mode? What exactly are you trying yo achieve? Do you want to flash another firnware, or just de-bloat your current firmware?
Hi
I guess I should have been a bit clearer, my plan/goal is to flash another firmware onto my phone
Maybe I should say why I want to get into the bootloader:
I want to install fastboot and I can't cause I can't get into bootloader

So if I understand your request, you'll first need to flash a custom recovery like CWM or TWRP, which you do via Odin. Once you have that, you can flash a new custom firmware as an unsigned .zip file. Follow the instructions here - this is what I used on my 925F.

Hi
I have installed TWRP recovery (and it's working just fine)
I've installed both the BL and the CP from this one
and I now have the baseband as stated in this (still unable to reach the bootloader)
the reason I wanna reach this magical place is so that I can install fastboot

Sorry, I'm still not sure what you're trying to achieve - you're obviously able to boot into Download Mode if you're now using TWRP (assuming you flash it via Odin). What are you trying to do via Fastboot that can't be done via TWRP?

Hi
I'm currently trying to install ubuntu touch on my phone as I'm using ubuntu on my pc and the only place I've found that helps with this that isn't over 2 years old is this one and doing the terminal commands requires the phone to be in bootloader mode or else it will not get recognized by the pc

Umm. . . According to that link you've posted, the Galaxy S6 isn't even supported. I suspected as much, as Fastboot is usually something you only see on pure Android devices (Nexus phones/tablets).
I'd strongly suggest you do some more reading on this before proceeding, as you'll almost certainly end up with an expensive paperweight otherwise!!

Hi guys,
Just recently purchased redmi note 3 pro 32gb from gearbest.
Phone should be international version with 7.2.13.00(LHOCNCL) preinstalled.
I found that I cannot flash any standard / developer ROM when official website by using built-in flash tool.
Any way to go from here? to at least receive OTA updates and in future I will like to try out Ressurection rom.
thanks.
Your ROM is unexsisting one, cooked by the seller.
You must flash a new one clean via EDL mode and MiFlash
This CN in the name means Chinese, and the numbers says that the rom is only modified to support more languages.

Does this mean i need to wait for unlock bootloader first?
my MI account has previous device linked which I just removed now and set to my new phone.
might take weeks to get approval?
or is there a guy to by pass the locked bootloader?
thanks.

No you wont loose your IMEI. Basically you are just flashing official MIUI Rom, your IMEI details are stored in another partition (non volatile) and FlashAll will not touch them.
You are safe to follow this guide, and by the way you would not be able to unlock the bootloader (the official way) from this vendor Rom. So if you plan to do so later, here you go with this first step.

Put the recovery image file in the folder from Unlocker.
Press Shift and Right click with the mouse on the empty space in the folder.
In the context menu choose Open Command Window Here
Put the phone in fastboot mode
Write in the terminal
fastboot flash recovery and write down the name of the image. For example:
fastboot flash recovery twrp.img
or
fastboot flash recovery recovery.img
Success.

Hi guys,
first of all: I am an idiot
I was using an old nightly from CM 13-kenzo and decided to do some preparation to finally migrate to Lineage without data loss.
So I wanted to go to CM14.1 before flashing the experimental Lineage and the nightly.
What did I flash with TWRP?
1.) ROM: cm-14.1-20161225-NIGHTLY-kenzo.zip
2.) GAPPS 7.1 ARM64 micro
3.) Firmware: CM14.1-firmware_20161205.zip
I think I should have flashed the firmware first, moreover, I didn't wipe caches.
What's happening now?
Recovery mode does not work (the display just flash for half a second)
Booting does not work (ofc )
Fastboot mode still works.
How can I fix this nice problem with Cyanogenmod?
Any help is much appreciated.
Bro,I also faced this problem. Just go to guides section and follow the guide"install zcx twrp without unlocking bootlader" one. And flash by that method twrp and you will get it all back.
I have also faced problem same you are facing and solved it!!!

. Your bootloader is lock, if you still can get to fastboot, then enter edl mode and use miflash to unlock yourboot loader again
Thx. Does Miflash work on a chromebook?

Yes, I mean Miflash tool. You need to folow this guide
http://en.miui.com/thread-235865-1-1.html
And remember you will lost all data in internal memory, you will get back to MIUI with that guide. Then try to unlock your bootloader officially or unofficially again.
Or if you woud like to take risk then you can try this way https://forum.xda-developers.com/redmi-note-3/how-to/unlock-unofficially-install-zcx-twrp-t3586778 without data lost

now bring your phone in action and turn on oem unlock from developer optipn(tap miui version 7 time and find developer option in additional option)
sign out of your mi account

That would be the impossible part. So I guess I've to work with the first link. Thanks.
So if you damaged the recovery and your bootloader is locked theres no way to rescue this phone without a xiaomi shop but good luck
Okay problem solved. I used this guide https://forum.xda-developers.com/redmi-note-3/how-to/kate-guide-install-lineage-os-locked-t3546154 and it worked like a charm.
Thread can be closed.
I have a RedmI Note 3 (kenzo) running Lineage OS 14.1
The RAM usage reports around 150MB of use only and there is no free RAM. So I think there is a problem with my phone and I decide to flash everything to start again.
I found a compatible kernel and flashed that new kernel and I got bootloop.
I read that if I flash the ROM again, the kernel will be replaced by the default one so I went to do that with TWRP.
Went to TWRP to flash my ROM and got error 7.
Read a bit more and I read that somethimes very old TWRP will show that message for new ROM.
Indeed, my TWRP was quite old.
Followed steps to flash my TWRP recovery to newer version in TWRP.
Now my TWRP recovery can't even work.
Try to flash ROM with ADB, but I forgot to enable debugging before bootloop.
Is there a way I can fix it?
I don't need the things on my phone.
I just want it to work again.
Thank you for reading and provide me with guidance to fix my phone.
Trying to flash MIUI ROM using MiFlash. Hope it works. Then I can work my way back to Lineage OS.
flash the miui rom using miflash by going into the edl mode from fastboot.

I will do that after some sleep.
I have another thing to worry about. The charge light is not on and my phone won't shut down. It can only bootloop or in fastboot. I put it on fastboot now. Still don't know how to shut it down or not sure if it is charging because there is no charging light.
I followed this:
https://forum.xda-developers.com/redmi-note-3/how-to/fix-bootloop-redmi-note-3-recovery-edl-t3521297
Flashed it, MiFlash says operation was successful but still won't boot up normally.
Now I don't have to worry about running out of battery because it boots to logo and turns off to nothing.

You might want to try and do a factory reset at this point and see if that resolves the issue. Alternatively, maybe trying loading the stock software ROM through download mode and retry the process.
