Xiaomi Redmi 9 (lancelot) hard bricked - Upgrading, Modifying and Unlocking

I bought a redmi 9 (lancelot) in November. After unboxing I came to know that it has google dialer and messenger instead of mi messenger and dialer as it was a global variant. I went through different forums and found out that only indian roms have mi messenger and dialer so I decided to flash my phone with an Indian rom. first of all I unlocked its bootloader via official xiaomi unlock tool. it took 7 days. After that I flash my phone in fastboot mode with a miss matched file it was "cattails" file. I didn't knew about its codename yet (and yes that was the stupid part where I kept continue my try to flash the phone ) .
somehow phone flashed successfully but it never rebooted after flash and gone dead. now its only showing mtk port and I am unable to flash its factory firmware. how can this problem be solved now please guide me.
I don't want to visit customer care center again as they told me to replace its motherboard as they do not have authorized mi account to flash the phone.

open phone . take out mother board .. and read plaque model. if sprint flash sprint KDZ and LGUP. if H815 then do that .. thats the only way to be sure.
U have a refurbished model.Go to nearest mobile repair shop & take out your motherboard to see what model no is written on this.Then flash a rom accoringly. Don't flash any other rom just by assuming else you will brick your device.
Yes my phone is refurbished...
But how to flash the rom?
If I found it to be a sprint version and flash a sprint rom ...it will be locked?I am using phone in India...
Any chance to root the phone and install twrp?
Then flash a custom rom?
Please help...

Most probably it will be locked cause most higher Android versions LG has blocked rooting or unlocking..But you can always browse few threads.
Mine is also a refurbished model with F500L motherboard,LS911 body & had H815 global rom installed out of the box.I am currently on F500L Nougat locked & unrooted..I have tried almost every method.It failed to root & even to enter fast boot.
If you get your proper model no on motherboard then just flash the rom with ToT flasher in download mode with respective DLL.

Thanks for your reply...
Your network is locked?
You cant unlock it?
Can we degrade our Os to lollipop to get root?
Even I cant turn on the Enable OEM unlock under the developer mode...
Any more advices?
Please help.....
I have tried almost all h815 ans ls991 roms with all flashing methods but still unable to successfully flash my device...lg tot flash tool always show dl error after 4 to 6 percent of flashing...
Please help
Any idea's?
Pick the phone, and send it to the place where you bought it. If you have warranty the repair is free, if not, then you must pay sadly.
Still no solution, I even cannot enable OEM unlock under developer options...
It automatically disables it...
Please help
Just experienced this issue after changing sim card... Call and Camera stopped working over and over again.
How I solved it: Go to the specific app that is causing you trouble, and clear cache/files (too bad I only found this after 3 factory resets).
Maybe it will help ... LG G4 CAM

Your device failed verification message after every boot

I got a z2 play today and right after the first start it turned off and this message started appearing (it's the same than on my g4 plus that has unlocked bootloader but the Z obviously doesn't
I'm from brazil
Do I need to get my phone replaced?
or is there any fix I can do myself?
Obviously this is reason for concern and but let me put a positive spin on this ...
Let's assume you got a new device (not refurbished / used), and the device is working just fine. This could be actually good news. Because that message usually shows up after unlocking the bootloader. Unfortunately unlocking normally cancels your warranty. You can only unlock the phone by requesting a special unlock code from Motorola. This way Motorola can easily check whether you unlocked your phone and decline (warranty) service. But since you have never done that, you might have an bootloader unlocked phone with warranty.
> or is there any fix I can do myself?
You could research "fastboot oem lock" but if the above is true, there will not be any advantage whatsoever to do that.
I faced the same issue
after normal use ,no root or unlock bootloader
my phone crashing frequently
and after reboot I Received that error
and I can't update anything via OTA
I started a topic at Lenovo Forum
an Expert suggest me to return it to vendor
so I return it the vendor yesterday
now I hope for a full refund.

I fixed it myself by installing the stock room via abd fastboot, if anyone is facing this problem, my phone is working normal and the message is gone so I bet I got a fix.

From fake Rom to china rom

Good day. I have a big request for more experienced forum users. What i should do do step by step with the phone if it comes from a global fake Rom to change it to the original Chinese one? I read on the forum that if i do it wrong i can block the bootloader for good and i cant upload later the global version from xiaomi. For this I am asking for help. What you have to do to upload Chinese Rom correctly without the problem with the phone later.
Edit In one of the threads there was information about blocking the bootloader if something goes wrong because the Chinese use the program to remove the lock and later there are problems. I want to return from fake Rom to the original so that you can later upload a real global. I am asking for directions as for a novice.
can help someone?
Better if you contact the shop/seller and ask for clarification. Whichever ROM you flash, you would modify the phone and liose the warranty, despite the fact you succeded or not.
Me, I personally prefered to return the phone to seller and have him reflashing the phone.
Inviato dal mio MI MAX 3 utilizzando Tapatalk
understand, but I just want to install the original software. In this case, it is a Chinese version. When the global version from xiaomi comes out I would like to install this version without any problem. I once to install roms in lg, huawei, but I do not want to spoil anything and I am asking for help in how to properly upload the original rom for the phone.
from fake to china rom
I received today my mi max 3 4/64 gb with fake rom. Perhaps my experiences can help you a littlle bit.
I first booted the phone and binded it to my mi account. (with sim inside) My phone was unlocked which is a must.
Then I followed the steps from omer919 in the thread Global rom will be released very soon.
I flashed the chinese rom, wiped/format data and dalvik.
I booted back to system.
After the phone was rebooted I booted back in fastboot without changing anything to the new rom (it is in chinese so that would be a bit difficult )
Then I flashed the latest eu rom via twrp - via the command prompt with fastboot instruction "fastboot boot twrp.img". Attention the latest eu rom doesn't allow rollback so if you want to put the global rom it must be on miui 10.
After flashing you reboot the phone.
You will not get in the phone, and this has noting to do with the flashing of the vendor wathever some person on xda will say. The reason is that you can not activate your sim - so no connection and no activation- it will be overruled by the xiaomi protection saying that this phone is binded to a mi account. (in fact your own account) You cannot push the wifi button on this screen to put in your wifi password.
How can you get through this :
1. first power down your phone.
2. Remove your sim.
3. reboot your phone
4. you will get the xiaomi protection but now you can push the wifi button and fill in the wifi settings.
5. push the back arrow and fill in your mi account password. push the activate button - It will activate the phone in your mi account.
Also no need to relock your phone as it is binded to you account.

Bricked Redmi Note 8 pro

Guys i just bricked my phone because of flashing wrong kernel. My phone isn't in EDL mode cuz my phone doesn't vibrates and in my computer's device manager i can't see it. How to unbrick it ? I think i will need an authorized account but i don't have it and any of near services doesn't have it tho. And for it's being global service. It is so expensive on the net that i can't afford it. It is something like 60$ in our country. and my wage is 300$.

Yup you are right bro it's too expensive on global. But there is no solution except it if you don't flash preloader and lk file which is described in mega thread. And you have to go service centre if you don't want to spend on online service. And your phone is in da mode which can be fix by sp flash tool which need an authorised account. But if you already flash preloader and lk than it don't need authorise account. Same happened with me and now I am waiting for opening service centre in my area it closed due to coronavirous. Hope your device will be fix soon.
If you got any solution than please inform me also.
