Hello xda,
So yesterday I made a mistake, lockedthe bootloader while being rooted.
Device is currently in a locked state:
- I can boot to fastboot and recovery but I can't flash or unlock the bootloader.
I have been looking for guides but afaik it's impossible to unbrick 8T's right now?
Tools aren't available yet.
Thanks

Hi.. I have Sony Xperia (ST21I) with build number 11.0.A.4.27 (android version 4.0.4). Few months before it rooted this phone with a unlock flash tool. I am sure that the phone is rooted now. And i managed to install a Clockwork Mod too with CWM installer.apk file. And tried too boot into clockwork mod. It worked. Now I don't know which bootloader I am having? A locked bootloader or a unlocked bootloader. This question may look silly to people who are really fluent to android. I never carried any process to specifically unlock my bootloader. I am asking this question because I have read that "You can't root your phone without unlocking bootloader". If what i read is true does that mean i am having a unlocked bootloader?? So now is it possible to flash a custom rom for unlocked bootloader? Thanks in advance.
only few roms

You probably have a locked boot loader as bootloader can only be unlocked by a specific key.
I too have a xperia tipo and it can be rooted without unlocking the bootloader. I used unlockroot to root it.
Thanks Guys!!

Thanks akash and slogger for ur replies.. Actually i sorted it out earlier itself. But unfortunately i didn't come here.. Anyway thanks guys..
Thread Closed, thanks!!
As I said in the title my device is G920FQ model. I want to try custom roms, is it already bootloader unlocked or is there a way to unlock bootloader? I've searched this place but couldn't find anything.
Also if it is bl unlocked can I just flash TWRP without rooting my device first?
EDIT: Got it all sorted out.

what i know is that u don't have to root before flashing twrp so just flash twrp fist and see if u can get into the recovery mode
so try to flash twrp and get into it try different ver. of it
if u can't try to unlock bootloader if it was locked and search google for (how to check if bootloader is locked s6)

My "Coolpad Note 3" is not booting into recovery mode after Flashing Cool ui 8 V22 Rom & TWRP Recovery. However Normally its booting absolutely fine and its quite stable Rom. But I seriously need to flash TWRP in order to install SuperSU and Xposed Installer. Anyone Please suggest any solution Asap.
(Also My Titanium Backup(Apps+Data) could only be restored after granting root access).

Did you flash the correct recovery for your model number?
Have you tried flashing the recovery again?
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE
Yes I Have flashed the correct recovery with SP FLASH TOOL (Mtk 6753 Scatter file). It shows that it will boot into recovery mode but again screen blanks and same process repeats.

Do you know of your bootloader was unlocked before you flashed the recovery?
If it was locked then that is why it won't boot to recovery.

Yes, it's the same for all android.
adb reboot recovery
This still doesn't work if your bootloader was locked when you flashed your recovery.
If the bootloader was locked, you'll have to flash a copy of your stock recovery.
Then unlock the bootloader, then flash the recovery. It will probably work correctly then.

As I Know, Coolpad Note 3 comes with pre-unlocked bootloader. And Earlier I had TWRP installed in it with the same method. I dont think so The Bootloader was Locked as I Have flashed Cool Ui 8.....nd that was done quite easily.

Ok, if you had TWRP on it before then it isn't locked.
Did you at any point create a nandroid backup while that version of TWRP was installed? Have you tried flashing that same version of TWRP?

Yes, those are nandroid backups.
Can you flash the recovery that you used to create those backups? Or is that the same recovery that you're trying to flash now but can't get it to boot?

I dont remember the exact version of Twrp as its not officially available for my device. But ya..I had tried to flash 2-3 recovery.img 's (including the one which I flashed earlier). But no one worked...it just repeats the same process.

The device may have came with bootloader unlocked when you got it, but you flashed a stock update Cool UI 8, if that stock update came with a locked bootloader as part of the update package then your bootloader is locked now, and that would still explain why you can't flash or boot to TWRP.
Verify whether the Cool UI 8 v22 firmware itself came with an updated and locked bootloader. It has nothing to do with whether your device came with unlocked bootloader.

Ya I Have checked...Coolpad has locked bootloader for this firmvare version. What should I do now....Should I flash the earlier version of cool ui 8 or Is there any method to unlock ot manually?
(Ps: Not able to find Adb & Fastboot drivers for this device)

I'm not sure about the bootloader, I didn't find anything about unlocking bootloader for Cool UI 8 v22. Does it have a "OEM unlock" setting in system settings? If so, enable it and then see if you can flash/boot TWRP. Try fastboot with the following command:
fastboot oem unlock
But I did find something about how to root your device, if the information is correct. You might be able to root what you have then use FireFlash or Flashify to flash the Xposed Framework and get it working. You probably won't have unlocked bootloader or TWRP though.
But, you also might be able to downgrade to your previous firmware but I'm not sure if that will unlock your bootloader or not. The locked bootloader might not allow you to downgrade your firmware.

I followed this method and successfully get the twrp installed and rooted my device. Thank You So Much To You too For Your Help Dude.
This is not a method to relock Bootloader
I see many threads opened on the same topic and closed!
I hope those threads fixed things for you guys.
My situation is Different!
This is not a duplicate Thread.
I just unlocked bootloader on my Zenfone 3 [ZE552KL 4GB 5.5' Model]
After flashing TWRP and using ROMs based on 9.0, I found that we cannot use
UPI [Payment Interface in India (GooglePay)] in the device!
I tried many methods to flash the stock ROM and lock the Boot loader again, But I cant lock it anyway!
I found a thread by @Saktis_Impreza on this topic but I get:
adb>fastboot oem lock
...
FAILED (remote: unknown command)
finished. total time: 0.014s
I would like to share an idea which helped me Regain Warranty after rooting
and flashing over several times on the device ZUK Z2 Plus.
I'm not sure if this applies to ASUS devices.
In Z2Plus we can make the device tampered flag to false by flashing an
older Chinese Firmware on the phone using QPST Flash Tool.
Afterwards we can flash the latest firmware to get back to stock with locked Bootloader.
I know I wont get OTA since I unlocked using the OFFICIAL Method.
I just need to Relock the Bootloader.
I Hope someone would Help.
Thank You

Hello anyone pls help
Actually you can relock bootloader by reflashing factory raw, typing in cmd "fastboot oem unlock" and then, with bl locked, reflashing the latest oreo raw.
My tool does it automatically.

You can unlock the bootloader only on A11, on A12 it is impossible. You need to go to A11, unlock bl and then go to A12.
