Bro u deleted your preloader. You need a Linux system to fix it. I suggest Ubuntu 16 with spflash and mtk bypass utility. And mtk client tools to unlock loader after flash.
[Redmi Note 9 Guides, News, & Discussion] VD171:
If you have backup of original nvram, just flash it and erase nvdata.

Nvdata will be rewritten using parameters of nvram.

Yes, actually I'm using this device and I don't plan to buy a new one for a long.

I'm always using stock MIUI, actually on V12.5.3.0.RJOMIXM.

I have two same devices (redmi note 9) but one has IMEI2 only.
[Redmi Note 9 Guides, News, & Discussion] Kaustubh Mishra:
Any suggestions on imei 1 fix ??

And btw have you ever dealt with a deleted preloader ?? This month was a rollercoaster of emotions. I somehow managed to delete my preloader by flashing official pixel experience 12 on my Merlin. My mom said she will take away my pc if i don't fix my phone. I used all of my device bricking and unbricking sh*t skills of 4 years. Windows wasn't recognising my device cuz no preloader. But Linux with libusb-dev installed did recognise it in bootrom mode. My 8 yr old laptop finally came to a use. I flashed preloader, unlocked bootloader and flashed stock rom. I was happy but all of a sudden I realised imei gone. This is how I met you. I see you every where with the word merlin. helping people. Man you're nice. Any ways, no way to fix slot 1 imei ?? I guess ??

sir i want to ask why when we use the imei kernel it can be dual sim
[Redmi Note 9 Guides, News, & Discussion] Kaustubh Mishra:
I don't know bro
[Redmi Note 9 Guides, News, & Discussion] VD171:
Because the kernel is the brain of the system.

The kernel decides what is possible and what is not possible.

So, a custom kernel can bypass the RSA signed IMEI if it decides to not perform checking.

Android uses the kernel most used in the planet, the Linux Kernel.

Linux Kernel is open source, so you can build your own kernel.

Some kernel for android are open source too, like the kernel for Xiaomi Redmi Note 9 Merlin:

does removing hardware protection have any risks?
[Redmi Note 9 Guides, News, & Discussion] VD171:
There will always be risks in using a closed source kernel.

You should choose the open source kernel ever.

thanks now i understand why xioami made rsa security system, it might be impossible to restore dual sim imei without side effects, but is there any official way to restore imei
[Redmi Note 9 Guides, News, & Discussion] VD171:
You can't sign if you don't have the keys.

The only way is bypassing the checking.
[Redmi Note 9 Guides, News, & Discussion] Kaustubh Mishra:
How ???
[Redmi Note 9 Guides, News, & Discussion] VD171:
That is the point.
[Redmi Note 9 Guides, News, & Discussion] Kaustubh Mishra:

[Redmi Note 9 Guides, News, & Discussion] Jssdje:
get rid of that resistor or use a custom kernel to bypass the rsa check

[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Hello guys, can anyone help me i need some guidance. My redmi 9 got hard bricked but i was able to repair him with SP flash tool. Sadly in the process i lost my IMEI. Also was able to repair him with Maui meta. Everything works fine, but now in WiFi list, i have this WiFi error called nvram warning 0x10. Im trying to fix ir but its seems Impossible. Already rooted the phone, trying to use some WiFi fix files but when i use the apk es file explorer, i follow tutorial but on data folder i dont find any nvram folder. I think its was deleted on the hard brick repair process. So i created a new nvram file with scatter file that was inside fastboot rom folder. Made some changes that were asked from a internet tutorial, and save the new nvram.img in the fastboot rom folder, I changed too some informations about scatter file. Some words that were written like none changed for nvram.img and false for true. Then I saved.

After that i flashed with SP flash, ONLY the nvram file and everything went fine as you can see in the pictures. Once more i installed twrp, root, but when I go to the folder data, i still can't find nvram folder. I don't know what I'm doing wrong. As anybody have a solution for this?
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
You need to activate Dev mode then on phone app click *#*#3646633#*#* go to connectivity tab and cds information and update Wifi Mac address from there if you can't find cds information on stock Rom try to flash eng Rom
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Will try that. Thanks for the fast response, i wasn't expecting that. Just a question what the hell is dev mode? Some program like meta mode? I wrote the number that you gave it and it went to this page. I'm such a loser. Don't understand anything. 😢

Edit: Dev mode = Development options? Is that? Already activated. I'm in the connectivity tab, now what? Don't see that cds information
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
Well if you are on stock Rom, theres is not cds information, to update your Wifi Mac address you gonna need eng Rom
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Ok. No problem with that. I already have here eng rom. Used to recover my IMEI back. But after flashing with sp flash, what comes next? What am i supposed to inside meta mode? As i said o used to put IMEI back with maui meta and doesn't have lot of options to do.
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
Goog luck , use *#*#3646633#*#* for update Wifi Mac address and Maui meta to write your IMEI then backup nvcfg, nvram, nvdata, protect1 and protect2 with any tool you have
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Thank you very much. Let me see if i understood. I have to use that number in eng rom mode? Then go to connectivity mode and find cds and write my wifi mac address? Just st fixing the wifi mac address will give nvram folder back? Then i just put the Andress, use Maui meta for IMEI and then flash the normal rom with sp flash and after install twrp and make the backup?
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
After updating your wifi mac address, there is should be no more nvram warning 0x10 on your wifi
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Alright! But in that case i still will not be getting nvram folder back? I mean, because i have this nvram warning but my internet is working fine.
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
As far as i know, Nvram Isn't folder it was a partition that contain data about your imei, mac wifi, mac bluetooth, i think you shouldn't worry about Nvram as long as your wifi and imei is normal then nvram should be fine
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
You're right. But i was thinking if i do what you say, write WiFi mac address, then IMEI recover with maui, then i could install TWRP make recovery still with eng rom instaled? And after that install normal Rom with sp flash, after that install TWRP again and install the backup made inside the normal rom? Or will backup made in eng mode be deleted after running the official rom? I could also backup the files inside an sd card.
[Redmi Note 9 Guides, News, & Discussion] VD171:
Just write a new wifi MAC using modem meta.

Good luck
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
Why not use sp flash tool readback ? That will make it easier
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Well i did that. I explained that in my first message. I created nvram.img from scatter file that was inside fastboot rom folder. Opened scatter file with block note changed two things from nvram text and then used sp flash tool readback to save the nvram on the computer. After that i putted nvram.img inside the official rom folder and changed scatter so i could add nvram. Then inside sp flash i only marked the nvram option and clicked download and everything went okay. But then still no nvram partition inside the data partition, i checked with root installed and es explorer apk.

Well I'm already in meta mode now what? Where i do write WiFi mac address, and first where do i get him.

Edit: think i found it 😄 now i write it where?
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
It should be around there check everything until you find it, update wifi mac
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Think i found it ☺️ Is it here down below? Where it says random mac address i Change the number for my wifi mac address, then i click on update mac. That's it? And after that i can just recover IMEI with maui meta, then flash oficial rom with sp flash or before leaving the eng rom i need to do a backup?

Edit: i did what i said now i got a pop up message saying to reboot phone.
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
Check your wifi , is it good or still have error ? For imei you can check by setting, is it still there or its blank, if it blank just use maui meta to write it back
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Where do i see that? Im not seeing any WiFi list to connect. About IMEI it shows up blanck will recover with maui meta again. I think i can only write him on sim card 2 if i try to write on sim card 1 someone told me it can give a error after flashing normal rom saying nvdata corrupted. Last time i did it that way.
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
Yes, if your planning to use stock miui you can only use sim2, dual sim only work with custom rom with custom kernel and patched md1img..
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
found the WiFi list and no nvram error x10 is not showing up anymore. ☺️ Thank you so much dude. Now only need to write IMEI and then flash normal rom with sp flash and that's it correct?

Edit: I'm seeing the IMEI toturial the guy it's saying before recover IMEI i need to erase nvram and nvdata with fastboot command. Do i do that or just skip that step and write only IMEi?
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
Your welcome, yes everything should be fine, when you using sp flash tool dont use format all+download, is gonna format your nvram then losing imei and mac wifi once more
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
If you erase it, you will lose you mac wifi then it need you to update the mac address again
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:
Alright then. Thank you for everything. You are a life saver 😉. The IMEI toturial that im seeing says before writing IMEI back i need to erase nvram and data first with fastboot command. Can i just skip that part? Doing what it says will not delete the WiFi Mac address or nvram and nvdata? I think i need to find another toturial, right? I can't trust this guy!
[Redmi Note 9 Guides, News, & Discussion] Rlucifer.01:
I have tried write imei once,its simpel turn off your phone, open maui meta click connect then plug your phone to pc, make sure you already installed the driver
[Redmi Note 9 Guides, News, & Discussion] Nicolasjfb:

scatter file from eng_rom (engeneered_rom) ????

by that, nvram.img have inside all stored IMEI and WIFI-mac_address replacement and modification that has done in eng_rom, right ?

After nvram.img is saved, (that means the device is stil under eng_rom) after that, you must flash device into stock_rom, correct ?

this means that, device is now in stock_rom ?
[Redmi Note 9 Guides, News, & Discussion] germanargentina:
Hi! First of all I want to thank you for all your contributions and help you've given to other users with this device

I wish I had read your posts before trying to fix my phone, it updated to MIUI 13 automatically and afterwards it kept turning itself off and randomly rebooting so I tried to flash the stock firmware again with SP Tools: ran into a couple of errors and did some stupid things like connecting the phone to the thunderbolt port instead of the USB ones and also did "Format whole flash except bootloader" but never pressed format all + download, somehow the device survived it all

Whenever I flash MIUI 13 the phone boots to recovery with "NVData is corrupted" message, I was able to unlock the bootloader and downgrade to MIUI 12.5 which apparently works perfectly fine (got wifi mac address, bluetooth, SIM1 is recognized and working for calls data etc) but now both IMEIs are shown as "Unknown" and I still can't update to MIUI 13

I really don't understand how the sim cards are still working, but I'm afraid to try fixing them because afaik the SIM1 is protected by RSA encryption

Do you have any advice for this situation?
[Redmi Note 9 Guides, News, & Discussion] Len0n:
Good night. A while ago I was updating my Note 9 from Miui 12 to Miui 13 without problems. Shortly after I wanted to customize the phone a little more and I tried to install a recovery where the whole process failed for not reading the forums well... It turned out that I clicked on "Format all" in SP Flash tools but before I made a copy of the ''Nvram'' or I think I did, since I can use the mobile network and Wi-Fi connection but the imei number does not appear and it gives me the error NV ram on the Wi-Fi.... If you can help me I'd really appreciate it if you could fix that...
[Redmi Note 9 Guides, News, & Discussion] daviddrf:
Hello, first of all I want to specially thank to @VD171 for all the threads in XDA with very valuable information about Xiaomi Redmi 9 (merlin), thank you again!

I have that smartphone and before I make any change, modification or mistake I read some of the @VD171 threads I said before.

First of all I am trying to make a backup of some parts of my phone (https://xdaforums.com/t/guide-how-t...d-on-merlin-redmi-note-9-redmi-10x-4g.4230423).

I unlocked the bootloader and I successfully bypassed authentication (I got a "Protection disabled" message in COM3 like in thread https://xdaforums.com/t/guide-how-t...nd-flash-in-edl-with-no-auth-for-free.4229683).

The problem is when I try to readback using SP Flash Tool. I configured the tool like @VD171 wrote (https://xdaforums.com/t/guide-how-t...-for-merlin-redmi-note-9-redmi-10x-4g.4229937) and I used his readback UI file (https://xdaforums.com/t/readback-fl...iaomi-redmi-note-9-xiaomi-redmi-10x-4g.422319) but I got this error message ("ERROR: STATUS_PRELOADER_INVALID (0xC0030004)):

My future goal is to flash a custom recovery and ROM (not the stock MIUI ROM) and then root the phone with Magisk or something similar (but first I need to backup the IMEI and some more information for being safe). I still haven´t flashed the patched VBMETA.img file (https://xdaforums.com/t/vbmeta-img-...iaomiredmi-note-9-xiaomi-redmi-10x-4g.4218909)

I don't know where am I making the mistake (¿maybe the scatter file or the download agent DA file?). If this helps you the phone is still untouched and I am using its Android 10 stock ROM with MIUI 12 which is not upgraded to the last one:

Thank you all for your help and support, sorry for any inconvenience and let me know if I can help you with more information if it's needed.

PD: sorry for my bad english language too!

https://xdaforums.com/t/guide-how-t...for-merlin-redmi-note-9-redmi-10x-4g.4229937/

Do I need any special scatter file for my phone if it is on Android 10 with MIUI 12?

I sent you a message through Telegram too.

I don't know why there's a "ERROR: STATUS_PRELOADER_INVALID (0xC0030004)" error code.

Hello everyone, I am a bit of a novice in recovering all this imei, mac, baseband, etc. and I really do not understand what you mean about what to do in this thread.

First of all thank you very much for all the support you can give me.

The case is that I have a merlin mobile that suddenly went into bootloop without any modification (stock), was taken to a technician and he managed to get it out of bootloop, but lost the baseband, imei, mac (Wifi and Bluetooth).

The little I did so far was to unlock the bootloader and patch the vbmeta with mtkclient and fastboot respectively (I think that way it will be easier to recover).

i have been reading many threads about the merlin device but i have not been able to come up with a solution (if there is one) so i ask you guys :)
