redmi6 stock rom full backup before unlocking or twrping

hi, i have a redmi6 cereus (type M1804C3DG 64GB) android 8.1 and i have upgraded from miui global 9.6 to miui global V10.2.6.0 (OCGMIXM) stable.
i have created a miui account and i’m waiting the last days for bootloader unlocking permission.
even if i loose warranty i decided to root it (the idea is to install twrp - the only way i know to make full backups and magisk).
but before i would like to know if there is any way to make a full backup of the stock rom as is (maybe before unlocking or before installing recovery) to eventualy restore phone as it came (if it has sense relocking bootloader and restoring stock rom) to see if in case it’s possible to try not to loose warranty
so is there any way to make a full backup of the stock rom (not in cloud) i mean to an sd card or to a pc to eventualy restore to stock if needed?

I can backup data partition only in LR TWRP. But i can backup everything else in every TWRP for R6.

good, tnx for the tip, i'll consider the second then.
unfortunately i'm blocked since more than 3 weeks and i don't know how to come out from an idiot message that says that i haven't used the phone enough.
the situation is this:
redmi 6 (cereus type M1804C3DG 64GB) android8.1
upgraded from miui global 9.6 to miui global V10.2.3.0 (OCGMIXM) stable
the phone is still always logged in the mi account from the beginning when i’ve tried to unlock
spent 15 days waiting unlock permissions but the result is that mi unlock (3.3.827.31 official) tells me is: "Couldn't unlock"
the dispotic reason in chineese ideograms reports: “The phone has not been used for the specified time and cannot be unlocked" 手机使用未达到指定时间，无法解锁 (with the button below “unlock again”)
after theese 15 days i'm still logged and i’ve spent the following 9 days using it more, but trying to unlock gives always the same idiot message
i feel rooked because i'm not the owner of the phone i've buyed
any ideas on any way to unlock?

* remove the account do a factory reset.
* re-add the same account.
* enable oem-unlocking & mi unlock permission in developer setting.
* download older version of mi unlock tool (I used 2.3.803.10)
* flash twrp & your flavours.

I had to wait 1 month for unlock. Maybe it might have got bugged. Try waiting for 1 month in total.

hey bro this was the key!! successfully unlocked, don't know how to thank you man!!
hey since i'm quite sure to have lost warranty, i'd like to be sure about the steps because reading around i saw that once flashed twrp to make it permanent i should wipe data and to disable force encryption flashing also lazyflasher or no-verifyencrypt so avoiding that at first reboot system re-encrypts again and that twrp will be replaced from stock recovery, is it right?
magisk a part, did you flash something else after twrp?

If you want only rooted system then just format userdata in fastboot then flash twrp and then flash disableforceencryption or lazyflasher then magisk through twrp.

Stuck on EDL Mode

Hi, guys. I have a terrible issue with my phone. I tried to flash stock ROM and phone get bricked. After that, i used a tool to flash without MiFlash but i miss the tool is for Redmi 3S, so i guess i mess up, HardBrick. The thing is that my phone is stuck in EDL mode, if i connect to laptop, that recognize QD Loader 9008 port. But if i flash again, i getting the error "writing exceeded wait time" and in times "only nop and sig tag...."
Any advices folks??
Edit: I used newest MiFlash and all good untill i get "No authorized Xiaomi Account can't Flash" message... Help please
Miflash Beta 2016: "cannot find port"
Miflash 2015: "catastrophic failure 0x8000ffff "

Dont worked any of the advices. The only method i have seen is to pay a s- unlock account (20-30 $) but i certainly need a china rom, and dont exist any for the RN 6 Pro, so i guess i have a paperweight instead :crying:

Hi guys, i need to tell you that i could flash via MiFlash with succeed. The problem i have right now that the phone is in Bootloop, even if i Flash again with newest MiFlash version. I have to say that im unlocked bootloader, what you recomend?

Had the same issue. Went to the service center and they flashed it and gave it back within 15 mins

As i have read in the article from the link below, even for EDL you have to have account approval from Xiaomy (which is paid i assume)...

Well.... after thousand of tries, i could bring back to life my device, only flashing Beta Pie Official rom via MiFlash 2018528. Only thing is that i missed IMEI

I have also watched before (maybe a year ago) some clips on YouTube how to bring back IMEI number (procedure for entering number, you have it on the box of the phone if you still have it).
Hope you will resolve it soon.
I will download MiFlash 2018528 and try to flash MIUI 9 to mine phone... I have read that MIUI 9.6.10.0 have ARB level 4, same as MIUI 10.2.2.0 so it should be safe to flash back to MIUI 9 (really hope it is safe [emoji53])

Well...i was.flashing 9.6.10.0 through MinFlash tool, and after some 130 seconds, some error has been reported (Failed to write - somerhing like that) and I'm stuck on Fastboot... Same thing is happening when i want to flash 10.0.5.0 or even 10.2.2.0 which was there in the first place...
Since it's stuck in Fastboot, i hope i didn't brick it... I have sent it to a guy which is an expert in these things, hoping to resolve ot successfully [emoji53]

You could flash back Beta Pie from newest fastboot without any problem

My problem right now is that i restore IMEI, but no signal for me. None of the sim card, even if the phone recognize that

How did u get the authorized ID?

could someone solve it?

[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.

Cannot upgrade to 12.5 MIUI

I have a Russian (thanks Amazon !!) Redmi 9a 32Gb/2gb. It is currently running latest 12.0.x ROM version, but i would like to upgrade it to 12.5.
I see on xiaomi ROM site there is currently a 12.5.x version for Russian version, but the OTA never arrived and if i download the recovery zip file and install it manually, it fails verification and stops.
Is there a way to install 12.5 without unlocking the bootloader ?
Is 12.5 supported on this specific redmi 9a ?
thanks !

mmm... spflashtool might work, but Ive only ever used it on a bircked device to unbrick it, never on a functional device to just change the ROM version, but if you really wanna do it without unlocking bootloader thats your best choice.
I will say anyway, its probably safer to unlock bootloader install recovery and install the rom from there, its your call tho.
Heres how I unbricked my device

Thanks
Right now I cannot unlock the bootloader, maybe in the next months I might try (I want to wait for the warranty to expire). My concern is that my version of Redmi 9A with just 2G of Ram is actually not compatible with MIUI 12.5. The 12.5 rom is actually available, but OTA will leave me in the 12.0 branch and verification fails if I try to install the ROM manually. I would not want to brick it by installing an unsupported ROM.

My phone model is M2006C3LG and the ROM I have right now says I have 1.8Gb of available RAM, I don't think you have a different device from mine.
Im a total n00b so I may be wrong about this next thing, but, I think the only difference is what version of MIUI they were sold with since the hardware doesn't allow downgrades further than the stock ROM that came with the device.
There is always antirollback after MIUI 10, but I think its even further locked for the original stock ROM that came to the device, but yeah, this is all my own speculation due to a bricking incident I faced.

The model number is the same, but the 9A was available with different sizes of RAM 2 or 3 or 4 Gb. Mine is the low end 32/2 which is the model still on sale today. If you still have 1.8 Gb of free RAM you very likely has the 3 or 4 GB model.
Maybe you are right, the OTA allows only for updates within the same MIUi version; I saw several guides on-line and i think i will try the miflash tool and switch to the global version. I have to find a way to unlock bootloader without Xiaomi account (no way in hell I'm signing up for that) and without sim card (this phone is used as a smaller wi-fi only tablet). There are some tools for an offline unlock, I will try those first.
It is incredible how Xiaomi is making it complex just to update to a stable official ROM; given also how much bloatware is shovelled with the stock ROM, I'm not sure I will ever consider Xiaomi again.

In my opinion, DON'T UPGRADE. I upgraded it with recovery and fastboot and my phone got an message everytime when I boot it : dm verity corrupted and I will need to press power button again to work. Maybe i didn't did that correctly ( I have Global 12.0.20 32/2gb)

Thanks for the info. So you upgraded to latest 12.0 without moving to 12.5, any reason for not trying 12.5 ? The phone is currently barely usable with Android 10, maybe Android 11 is even heavier, but why not give it a try ?
I saw several youtube videos and guides and by using MI Flash with a Fastboot image (scattered tgz) it should be a total reflash of the phone.
