Phone do not boot after donwgrade to android 11 - Sony Xperia 5 II Questions & Answers

I installed XQ-AS52_58.1.A.5.530_Customized EEA via NevFlasher and I have only information on the screen when I want to turn on the phone:
"You device is corrupt. It can't be trusted and will not boot". Somebody know how to fix this or what couses the problem?
I go back to android A12 (using NewFlasher) and phone is working but I want to install A11.
I have tried downloading ROM second time and use XQ-AS52_58.1.A.5.330, the same problem. I can't even boot to recovery in A11.

need to disable roll-back protection

It's the same as disabling Google verification (by removing google acount) or I have to do something else? I searched online but did not find anything specific.

you can learn how to do that in newflasher thread.

Custom binary blocked by FRP lock

Hi there,
I have a Samsung Galaxy Tab A6 (SMT-580) which I bought today. I followed this tutorial to install twrp, ultimately to root the device:
dottech .org/200476/how-to-install-twrp-recovery-on-samsung-galaxy-tab-a-sm-t580/
Everything worked fine and I was able to boot and reboot fine. Until I signed in with my Google Account. After trying to reboot, I get a black screen with the Samsung logo and a text in red saying: Custom binary blocked by FRP Lock. I went back to the store and they advised me to install Samsung Smart Switch to try and restore. In the Smart Switch program I get an error saying that the device is not supported by Smart Switch.
I can get into download mode, not into any other mode. The tablet doesn't start up at all. On the download mode it also says FRP Lock ON.
When I go back into ODIN and retry to install the from above TWRP image, it says operation failed.
Can anybody please advice? I am at a complete loss. Am I supposed to flash the original boot file? Where can I find that for my device? Will my tablet accept that, since ODIN didn't even want to flash my current TWRP image a second time?
P.S. I only read later that you are supposed to change the OEM setting. I didn't. Is that the cause of this issue, and if so, can I do something about it?
Thanks
Hi. Have you got it fixed yet? You need to download and flash stock firmware for your model and flash it in odin. Once it's done you have to enable oem unlock before you flash twrp. Let it be enabled as long as you you have twrp, root or anything custom.

ok, I read this is the place for noobs, so, I too got myself into a FRP LOCK on my Galaxy Tab A6 sm-T280. I use the tablet strictly for flying my drone for surveillance around the rural location where I live. It was having some connectivity problems, so I rooted it to hopefully get enough horsepower to run the DJI Go app. That didn't work so I did a wipe/factory reset, had a problem with the password, and here I am.
I am researching, and gathering the required tools to fix it.
I finally found some guides that are basic enough for me to understand.
I found numerous sites to download the stock rom, but not sure which ones are safe. Suggestions? Also, I am not sure about the country code for the firmware. I am in the USA, and I don't see it listed anywhere. Does it matter? This android stuff is all new and confusing to this old man. I am determined to get this tablet fixed, and would appreciate any and all advice. Thanks, Gary
edit: Will this rom work? : T280XXUOAPL1 using XAA for theCSC? Is xaa the default/generic for U.S.A. ?

Trouble in Rolling back to Stock ROM from OpenKirin on FRD-L14. Please Help~!

I tested the latest OpenKirin Omni ROM this weekend and decided to rollback to the stock OREO ROM on my FRD-L14. I followed the rollback instruction to the word - extract the image from the firmware downloaded from FF, flash the image file via Fastboot and I even relock the bootloader to turn it back to stock status.
However, I found that the phone contains only Huawei's software without any Google app. It is also impossible to input my Google account. After some panic, I decided to re-flash the ROM to try again but found I no longer can unlock the bootloader because the option got greyed out.
Now I have a phone with only voice and message access without any google app, so I cannot even brows the internet. Am I pretty much doomed? Please help!

Can you enter into eRecovery? In eRecovery, you can connect to a Wi-Fi network and install the stock ROM.

I guess you can go to the apk mirror website, download Chrome (or Firefox), Google play store, Android webview etc, copy them to the phone via hisuite, and install them manually after switching on "Unknown sources".
Also, i have the impression (someone maybe correct me) that the OEM unlock stays greyed out only for a few days, and it will enable itself.

[FIXED] Vicious cycle for Relocking Bootloader and Find Device Storage Corrupted

Greetings. After trying Derpfest on my Redmi Note 7 Pro, I decided to switch back to MiUI. I wiped out the entire Custom ROM, then installed Indian version firmware, and then installed the latest MiUI ROM in recovery mode (I prefer Orange Fox). After that, I wanted to relock my bootloader so I got the latest MiUI 11 fastboot ROM and then used MiFlash and used the clean_all_and_lock option. My device relocked it's bootloader, however, it turned out that several things like sensors or Find Device service were not working correctly. It also showed a message "Find device storage corrupted, your device is now unsafe". Looking for solutions, I ended up unlocking the bootloader again, getting back OFox, and installing the persist.img file which I extracted from my fastboot ROM. This fixed the issue with the sensors. But now, I still can't get access to services like Find Device (both from Xiaomi and Google). If I have to avoid the 'Find Device Storage corrupted' error, I have to unlock bootloader. If I have to lock bootloader, I get the error message. What am I supposed to do?
I also have tried older Fastboot ROMs, although they were all MiUI 11. Should I try fastbooting into a MiUI 10 ROM and then get OTA to do everything else? If this is the case, which specific version of MiUI 10 ROM should I flash? I can't remember which version my phone came with. My model number M1901F7S. And also, I've never used Magisk. I didn't really care if I wanted to root or not. Derpfest passed Safetynet pretty nicely. But now I do not wish to root. I don't want Magisk or anything else, I want to secure the phone just as it was before.
EDIT : Turns out that Find Device (from both Google and Xiaomi) are actually working, just in a less effective scale than what I previously used to have (before getting the custom ROM). But yet, can I bring my phone back to the locked bootloader state? I want to secure it completely, just like how it was when it came out of the box. I also cannot install apps like Netflix. I would really like to know how to relock my bootloader.
EDIT 2: I've fixed it. Indeed, I had to flash a stock MiUI 10 ROM. Version 10.0.2 and whatever number ahead worked for me and gave me no problems, and then I simply updated to MiUI 11 using OTA Updates.
However, I do not recommend using MiFlash tool, and instead recommend pasting the ROM files into your platform_tools folder and then running flash_all_lock/flash_all. MiFlash may sometimes glitch and cause problems.

If the phone had the latest firmware it's highly unlikely any method will now work. People have stopped making a fix for FRP lock because the S7 is a few years old now.
Why can't you use the Google email and password that was used on the device?
Also you cannot flash older firmware than was already on the device, only able to flash newer, never older. There's isn't anything wrong with your pc as long as you have Samsung USB drivers installed.
If you don't know the Google email and password used with the device (it would be the same one you use for Google mail) Then only s Samsung shop can reset the device due to the above.
hello
The only reason I can't use or login with the previous account cause this wasn't my phone. the previous owner forgot the account and given me the phone for free cause he couldn't do anything to it. But I have latest Samsung drivers installed it's just everytime I connect the phone to the computer it says "usb device descriptor request failed" I don't know if I'm doing anything wrong on my end or not please help cause I can't flash the newer firmware that has a method to unlock.

Problem with update miui 12

Hi a few months ago I switched from global to eu after some time I wanted to update miui to a newer version but an error appeared (check ss) I've already installed a few twrp, including the latest and several recovery versions available on the forum (orangefox)
Can somebody help me?
Did you format data before installing?
Yes i did it
Maybe you can try a fresh install with a miui 12 fastboot rom .
@alibei I will try and speak up

Hello, I found a solution to my problem, so if we have a screen lock (pattern / fingerprint), you should turn off the lock in time, it is a security that "prevents" deleting data from our phone. I personally do not believe that such a screen lock is able to prevent theft of the phone with an unlocked bootloader but somehow it works, also the update installed, you can close the topic
