My phone not booting its saying corrupted
Have you unlocked the bootloader? My first guess is you tried to change something without unlocking the bootloader first.

I've tried and tried and tried, but every time I try to flash the tar, I get a "Complete(Write) operation failed" error. Now I'm starting to think it's the bootloader's fault, since on my phone, it is locked.
Maybe that has something to do with it, but I don't know. You guys are the experts!
If your bootloader is locked then you are out of luck as it won't flash anything that is not signed by the oem and when you change it the sim changes.
Hi,
if you are talking about Odin, you have a Samsung phone. On Samsung phones, you can't unlock or lock bootloader. You can flash without doing anything.
Maybe the reactivation lock is active.

Just decided to unlock my bootloader since the DRM fix is not much of hassle anymore, and this way I can run some of the nice kernels available for our device, so I backed up everything on the phone and proceeded with the unlocking (expecting a factory reset/data wipe), I've had my device unlocked/relocked before, and even restored my original TA partition at the time since I had a backup, but when I unlocked my device today, that was it, no data loss or factory reset happened, not even a warning from flashtools about it, flashtools said "unlocked", I rebooted the device and everything worked without even reflashing the rom or even a kernel.
I'm pretty sure my device was bootloader locked because I used the TA-backup app to restore my TA last time, and once that happens my understanding is the bootloader gets locked automatically, plus all the DRM features were working fine (camera,sound) without flashing the DRM fix (I updated/flashed multiple LP/MM stock roms since then).
So my question is : did sony remove the factory reset on unlock/relock, or is my device just doing something on it's own ? just curious.
That's interesting. Perhaps they did update the bootloader with a firmware upgrade, but I highly doubt it, and it probably has something to do with your procedure (unlocking, relocking and unlocking again) because it would open a big gapping security hole for personal info.
eg: Nothing keeps me from stealing someone's phone, reading the IMEI, requesting an unlock code, unlocking the BL, flashing a custom TWRP-enabled kernel, dumping all device data to SD card and stealing all of its info. This is why unlocking the BL wipes the device.

I know, but at least for me this is 100% working, I even relocked my bootloader, flashed the TA backup to get the DRM keys back, and still nothing changed, and I made sure after the unlock to check that DRM keys are gone (camera quality) and flash a custom kernel, to make sure it was 100% unlocked, and it was.
Since relocking, I did a full .291 flash using flashtools, I was hoping some interested dev can pick on this, it might be helpful to use for exploits or something, no idea tbh.
When I went into fastboot mode it says its unlocked.
(I don't remember unlocking it, but I might have and just forgotten)
I still can't flash TWRP because it'll give me FAILED: remote command not allowed.
The internet says that it may be because of FRP still being locked??
So I have to restore it back to factory settings.
I'm afraid it'll relock my bootloader too.
Since the phone is already unlocked, is it possible to retrieve the unlock code?
PS. Phone is still in stock condition. I don't have root, nor a custom recovery.
Sorry if this is a stupid question but what do you mean by FRP?
I impulsively unlocked the boot-loader on my Mate 20 Pro last night because Funky Huawei was selling the codes for $20. Today I can't really think of a good reason I actually need the bootloader unlocked since I have no interest in rooting my phone and there are update methods for manually flashing firmware that don't require an unlocked bootloader. In fact, the tool posted on XDA for updating firmware with an unlocked bootloader apparently requires that you be rooted to use it.
Is there a way to relock the bootloader?
The only mention I could find in these threads was someone who said you need to factory reset the phone and then go back into fast-boot. I don't think the person who wrote that even tried it and that he was just making a generalization.
Does anyone know if there are actual steps that relock the bootloader without bricking the phone--which the e-recovery restore method might do since it will try to install an older firmware than is currently on my phone.
I might just keep it unlocked anyway but I was curious if there was a known relock method that works on this phone.

Use dload method, but pba that will erase everything like your 1st setting of your phone. Phone will be locked again, FRP will still unlocked.

does dload method altso come with recovery_ramdisk fixed? for us that have modified it for root or twrp??
So that the device becomes out of the box like new?
Yes, recovery_ramdisk back to stock with dload method

i can confirm dload method lock back the bootloader.
i had install an alternate fw but was not satisfied cause too much features were not working, i used first erecovery to download official fw but unlock bl was still present. then i try dload and phone was completly reset with bl locked.
dload method isn't working for me. I extracted the UPDATE.APP from the firmware version that is currently installed on my phone (using the update_full_base version), created a dload folder on my external card, copied the UPDATE.APP into that folder and then did the dial code and selected update from memory card. My phone reboots and then I get an error that says that the update failed.
Do I need to use the UPDATE.APP from a specific build to get this to work?
I installed firmware via the Funky Huawei method. It seems to have relocked the bootloader because the warning about the bootloader being unlocked doesn't come up when the phone boots but the data on my phone wasn't erased. Can the bootloader be relocked without erasing all the data on the phone? If so this is the first I've heard of it.

Go to fastboot mode and check if bootloader is locked again.

Will we able to reclaim warranty after relock? Anyway the service guys would be able to know that the bootloader was unlocked before?
Soo what is the legit way to relock the bootloader and the FRP?
is the FRP from stock/defualt locked?

Hi,
I was just wondering what makes a bootloader locked or unlocked. I know what bootloader unlocking is, but what actually changes in phone to make it stop checking boot, recovery and other partitions? And how do it knows if a partition is stock or not?
Thanks.
