[Q] Bootloader locked and phone flashed

hello,
I wanted to install on my 12 cyanogen lt18. My bootloader was unlockable.
I asked with my sony imei unlock code for and then I made handling with fastboot. Fastboot said he had succeeded.
Then I erased everything (erase system bootloader userspace), and do fastboot boot boot.img to install the cyanogen kernel and recovery.
Once the fastboot boot command is launched and successful, the phone switches off. Can't access to recovery.
I installed S1TOOL and it says my bootloader is not unlocked. What can i do?
Thanks for you help

If your PC can detect the phone, then try repairing firmware through PC Companion.
If not, then try flashing stock firmware (ftf) through flashtool.

New try :
I saw "legacy xperia" on the screen. I think that means that my bootloader was well unlocked. Except that then it shows me the image of the empty battery and the phone turns off. The battery is charged ...
12.1 recovery don't work but freexperia clockworld recovery is ok...

No issue to boot the cyanogen 11 recovery too.
But can't with 12.1. I think its a cyanogen issue.

Cannot flash and boot into TWRP on my Zenfone 2

Hi,
I'm trying to flash TWRP on my Zenfone 2 Z00A but it won't work. I cannot boot to TWRP.
My device is unlocked and rooted and I can flash boot.img, droidboot.img and stock recovery.img but TWRP IMG won't work.
After flashing TWRP using command "fastboot flash recovery twrp.img" and trying to boot into it nothing happens phone restart and boot to bootloader asking me to choose "Normal boot", "Recovery mode" "Reboot bootloader" ect.. and when I select "Recovery mode" phone restart and boot again to Bootloader not TWRP.
I also tried to flash TWRP using "Rashr" same problem not booting to TWRP.
Tethered CWM is working and I was able to boot to it but not TWRP
On the other hand if I flash back stock recovery and boot to it boots just fine.
What's wrong? Any idea guys?
Thanks in advance..

So, you've unlocked the bootloader or did you skip that part?

Yes it's unlocked.
When I flash TWRP via CMD using fastboot command it shows successful writing TWRP IMG file. Otherwise it will show permission denied if the bootloader is locked AFAIK.
The splashscreen is white which means the bootloader is unlocked. But I don't know why it's not working.
Device is CN version flashed with WW firmware.

TWRP App-based installation
I've also tried upgrading to twrp-2-8-7-2-Z00A.img from within the TWRP Manager app. It seems to download and gets to the "installing/verifying" screen, then dies after a minute or two. The phone is rooted and unlocked. But after about the 4th or 5th try, it worked.

Ok problem solved
It turns out there was a problem with the bootloader. I used the adb commands to unlock it and it was showing successful but some how it was not unlocked fully as it seems.
The splash screen turned to white after unlocking the bootloader so I thought it was unlocked. I even tried unlocking it many times and every time the adb results were showing bootloader unlocking success but it tuned out it wasn't unlocked fully.
Today I used the official bootloader unlocking App from ASUS and unlocked the bootloader. I flash TWRP again and rebooted to recovery and BAM ! it booted to TWRP

Hello, I have similar problem with my Zenfone 2 Z00A. Bootloader seems to be unlocked because of white splash screen on start-up, but I cannot flash TWRP recovery via fastboot flash recovery ***.img. The process shows no problems/errors but despite that no TWRP after reboot.
Can you explain how you found out that bootloader was not unlocked fully?

I don't know why but after 4-th or 5-th attempt TWRP finally loaded.

Hi, I have a similar problem with my zenfone 2 z00A. My device is not rooted. I tried to use the process described here.
Installation
Latest releases, tools and general information
groovyandroid.github.io
I tried bootloader unlock process with the app on my phone first, but after 4-5 times of use, it always came up with 'Network error'. I went with the 2nd part of unlocking bootloader to transfer TWRP imgae file. Now the phone is starting with a white splash screen and showing 4 options: Normal boot, Power off, Recovery mode and Restart bootloader. I have tried fastboot flash recovery twrp.img and fastboot boot 'twrp.img', but still can't get to TWRP recovery process.

Unable to flash custom recovery

Hi,
I have the Find 7 with the new display panel.
I wanted to flash the latest version of TWRP but failed. I do not know what I did wrong.
I can use adb and fastboot without any problem. When trying to flash recovery, it says there that the flash was successful but when I reboot to recovery, TWRP was not installed and the original Oppo recovery is still there.
The bootloader is unlocked. And I tried relocking and unlocking again but to no avail. Whenever I use the command "fastboot oem unlock", nothing happens to the phone.
I am currently on spectrum. I want to try other roms such as the lite COS 2.15 and also maxwen roms since that only those supports the new panel.
I am also trying to get root for my phone and it is impossible without custom recovery.
Thanks for any help.

I had poop loads of issues with getting custom recovery on my Find 7a. Eventually I used these instructions:
http://community.oppo.com/my/forum.php?mod=viewthread&tid=996
They work. Don't know if it's the versions of ADB or Fastboot or something.
Give it a go

I will give it a go when I get back. Thanks!

This is what a forumer from the official forum said and it works:
After you had successfully flash recovery via fastboot, you MUST NOT reboot the device. AFAIK, if you reboot the device it will restore the recovery back to stock oppo recovery.
So instead, you need to immediately press vol down & power button on the fastboot screen. Keep holding the button until you see the TWRP recovery screen. Hope that helps. Cheers!""

Unlocking bootloader erases data?

Mine wouldn't flash recovery. It said successful but I still had oppo recovery 1.2 and it only worked when I found the latest official twrp over version 3. after flashing, I disconnected usb and then held down power button to shut the phone down. It then was able to boot to twrp ok.
I used the latest one.

Semi-bricked XA1, possible recovery?

So my phone has been lagging a whole lot using the stock rom and I have decided that I'll try a custom rom to see if that changes anything. So I came here and saw this forum:
"https://forum.xda-developers.com/xa1/development/half-gsi-oreo-8-1-t3902259"
I thought I'll try and so I unlocked my bootloader, only to have my phone be reset (not a problem, everything was backed up). It also boots with a warning "Device unlocked and can't be trusted".
Then I went on to download TWRP using this link in that post: "https://mega.nz/#!FQFXCYSY!DgxQRkaY1Eqq3B0fZLEQBNzUs0Zj80L6IzSHxdorQ3A" which is the TWRP 3.3.0.0 V2 IS FOR ALL USERS.
I didn't want to flash in the event it was the wrong recovery so I tried booting into it, fastboot boot recovery.img
It flashed, everything was ok and now the phone doesn't boot. It stayed in a boot loop. I went ahead and flashed recovery this time, no luck. Downloaded a recovery.img from another website and it didn't allow me to boot to android or recovery.
Is there a way to save my phone, I can't get another phone until August due to contract. It can still boot to fastboot and gets stuck when trying to boot to android. It being able to boot to fastboot makes me think theres a chance to flash a stock rom or any custom recovery and rom to get the phone working again. Any help? Thanks!

OK use the boot.img and recovery.img made by @janjan HERE. Under the heading ¨Downloads¨ see ¨Xperia XA1¨ and download the KERNEL + RECOVERY the boot.img and recovery.img are compatible with the G3121-G3112-G3125-G3116-G3123 devices on the applicable firmware.
Flash BOTH using fastboot. The boot.img is patched to allow TWRP to boot which it will never do using the stock boot.
If you wish to go back to stock then simply use FlashTool to flash the stock fotakernel.sin and boot.sin contained in the firmware for your device.

Does it works becouse I boot my g3116 from flashtool camand was
Fastboot boot boot.img and then also it's stuck into bootloader

Flash phone rooted ans oem unlocked ?

Hi,
I recently installed magisk, then xposed and my phone went into bootloop. I reflashed with original boot image and wipped data and it was starting ok.
Then i installed magisk threw TWRP.
But the OTA would not work.
Si I'd like to flash the stock rom to restart from zero.
Can I just flash it like that, with mi flash ?
Or do I have first to unroot ? And to relock bootloader ?

no need of unrooting and never lock your bootloader with custom recovery or rom .
I recommend you to flash the stock rom in edl mode , connect your device in fastboot mode to your PC and open command prompt in your adv/fastboot folder .
then type the command : fastboot oem edl , the screen of the device will turn off , but notification led will blink , then flash stock firmware via MiFlash, after flash completed , hold power button for about 10 seconds(until you feel the vibration)

Thanks Mate ! I do this rght now !
(my phone is out: only starting if I install magisk with TWRP... Flashing the stock boot img will go in boot loop. So weird that let's go back to the stock )
