Hello guys I'm trying to save my bricked P20 Lite but I am running into some issues. I unlocked the bootloader using testpoint but twrp won't flash or boot. Flashing gives me a flash write failure, booting gives me a invalid command error and I can't wipe cache either. I could really use your help.

"flash write failure" - it might be due to a locked bootloader or hardware issue, AFAIK.
Try explaining what exactly happened, step by step.

I unlocked my bricked P20 lite bootloader with the test pin method, then I tried to flash TWRP in fastboot and I got those errors.

Are you sure that bootloader is unlocked? (With unlocked BL you will see that message each time when you reboot: "Your device has been unlocked and can't be trusted").
Have you enabled in Developer menu
"OEM unlock" ?
In fastboot mode run commands :
fastboot oem get-build-number
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the results.

1. Yes I do get that message that it's unlocked.
2. My device is bricked so that's impossible to enable. I unlocked it after it started bootlooping.
3. Gonna do those commands and tell the results
(bootloader) :ANE-LX1 9.1.0.372(C432E7R1P7)
(bootloader) ANE-LX1
vendorcountry: hw/eu
(bootloader) :ANE-LX1-CUST 9.1.0.7(C432)

What shows Fastboot screen, at the bottom, Phone unlocked and FRP unlock ?

Probably your emmc memory is fried. Not being able to unlock BL & FRP permanently is a sure sign. But I'm just an amateur and an android fan, maybe I'm wrong.

It does have water damage could it be because of that? That would be unfortunate.

- known failure due to water exposure , although the write failures are intermittent.
P.S.: since January are you trying unbrick a water damaged phone?

Nope i already know it was dead (repairs say it was total loss) but when I saw the new unlock method I thought it might be saved. Guess I was wrong but oh well I tried anyways.

I don't even get to fastboot part - every time I reboot with adb reboot bootloader the tablet goes into some mode with a black screen, green led indicator and fastboot devices returning nothing.
At the same time the device is recognized by windows as something S1???? and unknown driver, and I totally failed to find a proper driver for that.
Any help will be appreciated. Btw, Windows 10 here

Some bootloaders are unlockable. Mine is the same way. I have to wait for a root method that does not unlock the bootloaders.

to be expected with SGP712 and SGP771
Maybe with some provider branded Tablets in Japan they are "not unlockable".

Necro to say: YES, you can run "fastboot oem lock" to RELOCK the bootloader. "fastboot getvar unlocked" returns "unlocked: no".
Just tried it on my (two hour old) phone here.

relock with MIUI 10 Global Beta installed?
@smokin901 @AkkiV
-When unlocking, does the hard reset occur? (factory reset, or reset data)
No, unlike unlocking HTC, Motorola ... unlocking occurs without loss of data but if the data on the phone is encrypted, you must first disable the encryption, otherwise the data will be lost. Then unblock and you can turn on encryption again. Exceptions are Mi6, Mi Note 3, Mi Mix 2, Mi Mix 2s. They have a complete discharge. And it looks like this trend applies to all fresh models.
Click to expand...
Click to collapse
Does this apply after relocking?
It is better to opt for encryption since in Mi devices unlock won't erase my personal data...?

For example Mi 8 Chinese Ver. if you want to relocking bootloader from Chinese Vers. you have to flash Chinese ROM, if you flash Global ROM in Chinese Ver. device, you may brick your device.

You can claim warranty with bootloader unlocked, TWRP installed, rooted and with custom ROM. Water damage will result in no warranty.

AFAIK, warranty for Xiaomi devices remains intact even if you unlock the bootloader.
Obviously you can lick your Bootloader if YOU'RE ON THE STOCK ROM.
You can flash the stock rom with fastboot and select
Clean flash and lock
And your Bootloader will be locked.

Why do you want to lock? It is better to remain unlocked once you have unlocked. In the event of you deciding to flash a custom ROM, you have to unlock again and your data partition will be wiped.

Sounds like your bootloader is still locked, just because you flipped the OEM switch doesn't mean it's unlocked... Go read over here before you do anything else.. ( https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/ )

Thanks, that's a good guide. But when I try to run "fastboot -i 0x0fce oem unlock 0x<insert your unlock code>" it always returns that the command's syntax is incorrect. Is this because I don't have 26.0.2 platform tools?

Actually I sorted that out, I was entering it with the brackets when I was meant to remove them. But when I enter it now, it doesn't tell me incorrect syntax, but tells me instead "unknown option: -- i" I wonder if this is an issue of using too new version of Platform tools? (I'm using 28.0.1)
Right I figured it out. Just omitted the -i option and it worked. So it looked like "fastboot oem unlock 0x<unlock code>"
no further issues cheers

Google 'unlock xperia bootloader', and check the xz1 compact forum for the DRM backup method for your phone. (I know you said you have a xz1)
You need to unlock the bootloader using a code from sony, and enter it via a fastboot command before twrp can be booted/installed.

The "fastboot oem lock" command does not exist, it is certainly not a normal way
The best method to lock bootloader is searching for the Service rom on https://androidhost.ru/ and doing the dload method. Process will erase all the data from your device !
(Before you do anything, read carefully Software Upgrade Guidline in "ReleaseDoc" . With Service ROM you will get full stock with locked bootloader (warranty will not void any more).)
Hi thanks a lot for your reply, Unfortunately I cannot find such rom on the site for the life of me.

Connect your phone in fastboot mode to PC , open 'Minimal ADB and fastboot' and use command

Unfortunately not even HuRUUpdater 0.4 is working with this particular rom it reports unknown error so I am at a complete loss really
