What locked bootloader?
Hi there!!
I am trying to unlock bootloader in order to activate OEM unlock option, but I fail.
I am downloading through odin3 the twrp-3.1.0-1-chagallwifi.img.tar file but when I reboot in recovery mode, TWRP does not start.
Please, any help?
ps. My device is not rooted.
Thank you in advance.

You probably didn't boot to recovery immediately after flashing.

Maybe I didn't uncheck the auto reboot option from odin the first time. But at the next attempts I boot in recovery immediately.
Is there something that I can do now?
Is it a problem that my device fits the snapdragon processor and not the exynos one?

I recently got the Xperia S {No SD Card Slot, 32gb internal Storage}
I know it may sound silly, but could someone point me in the right direction for Flashing and Rooting this, what what's the best Rom/Kernal/Recovery Menu for this awesome device?
Just want to say, I do have experience on flashing stuff, installing roms ect
Just wondering what tools are needed to Root and Flash this thing
Thanks All!
this is the xS index for tutorials and guides and everything in between
regarding the part about best rom, you're always gonna receive a biased opinion on that coz that pretty much boils down to user preference

Check first: *#*#SERVICE#*#* >>service info>>configuration
if it says Bootloader unlocked allowed=yes then try as explained below ! It will definitely works !
I suggest you to first unlock your bootloader via the easy tool described at here http://forum.xda-developers.com/show....php?t=1560613
then flash the Doomkernel with the flashtool booting at fastboot mode. Before doing that never forget to install the necessary drivers.
The kernel is preloaded with custom recovery CWM and TWRP. While booting when you see doom logo pressing at 'vol +' you'll get CWM and pressing at camera button you'll get TWRP.
And flash the su and busybox package via recovery (CWM or TWRP)
for flashtool http://androxyde.github.io/
for kernel and su & busybox package: http://forum.xda-developers.com/show....php?t=2305591
& then enjoy Rooted jelly bean
ALL THE BEST !

You can root it, but you can't flash custom ROM's.

Install RootCecker and see if it is rooted. After that you can also try this SuperSU-1.25-Busybox-1.20.2-UPDATE.

Generally speaking: Install bootloader only with Odin.
You should now flash firmware using Odin to save your device. Maybe Kies could restore also.

HERE you may find firmware for your country/device, download.
Start Odin, connect your phone in download mode to pc, see if Odin shows up com-port and flash firmware in tab PDA/AP.
There are several guides on youtube/google
Cant Find my carrier
my carrier is international, only countries are on that list, I dont know which one to choose, also if im gonna flash firmware is it possible to flash 4.1.2? or 4.2.2/4.3?

Depends on your last firmware. What was the bootloader version? If above MJ5, you can't downgrade so you are free to flash eg latest 4.4.2

1. Never flash bootloader through recovery
2. I assume that you have had newer bootloader than MJ5 before flash, so you soft bricked your device
3. To regain full funtional device follow post #4

im having trouble , check my post here : http://forum.xda-developers.com/gal...m-via-odin-t2868125/post55256421#post55256421
Tried looking through threads and have spent all day trying to fix it.
Phone was working fine a couple days ago until it ran out of battery. Since then nothing.
If I try to turn on normally I get stuck on the Google screen. Only other thing I can do is boot into fastboot/bootloader but from there, if I try Recovery mode it sticks in a bootloop
I think you have a hardbrick bootloop, There is fortunately a kernel and recovery developed by developers to overcome this problem, but you'll need a unlocked bootloader as it involves flashing recovery and boot.img. If you have boot loader unlocked, go to general section where you'll find a thread regarding the same. All the best
I tried that - flashed the recovery but when I try to launch recovery mode I just get a bootloop again.

If you can unlock the bootloader again, I'd guess the flash didn't manage to erase everything.
Normally you'd have to boot and enable OEM unlocking before being able to unlock bootloader.

Did gsi android 10 flash recently?
if the answer is yes
with the bootloader unlocked you must boot twrp and flash stock-repartition.zip
You can now block the bootloader in stock without bootloop

There is another way too. Put your phone in EDL mode (fastboot oem edl) and flash the stock rom again. Even with clear_all_lock option enabled ,your phone won't lock your bootloader. When the phone boots up after flash,and you see the boot screen wait until you see erasing circle,after the second reboot,hold VOL - and power button until you go in fastboot mode. Then on your PC type: fastboot oem lock. The phone will boot up,then it will erase user data ,and you are ready with locked bootloader. I didn't have the stock repartition script ,so that's what i did.

If it works unlocked but not locked, something is modified. Leave it unlocked or flash a complete stock rom.

Probably something failed to flash. I don't know how much error checking the script has. Try again? Take note of the output, looking for warnings and errors.
Hello there.... I am upgrading from note 10+ n976B model to note 20 ultra, and want to completely return to stick...

flash stock with Odin, it will lock the bootloader, the knox fuse is definitely blown - if you do it correctly it should not be an issue.
ofc all the risks are in your hands, because you are doing it

it is the first step - after that you should enter download mode and choose vol up to LOCK the bootloader
it will erase everything on the phone tho

if the phone is unlocked, that option is greyed out - but to actual lock the boot loader, flash with odin is required
