To resurrect the phone, you will need a MI account with authorized access to the EDL. Look at the topic of Redmi 5 as they resurrect bricks. On our forum, several MI 8 & MI 8 SE have already been resurrected in this way.

[Xiaomi Mi 8 Questions & Answers] StarwarsMissionary:
thanks for the suggestions guys I was thinking before getting super technical opening up my phone and modding a cable to let you guys know of an update. Last night I stayed up a while i found adb flash tool for recovery mode to flash back to official software (http://www.xiaomitool.com/adb) I downloaded both global and both china otas of stable and beta. First i flashed global successfully but forgot that going from china to global requires unlock boot loader to boot up so it did not boot next I tried china stable but the file is an older version and did not flash since it was "downgrading" and last I tried china beta which was newer in theory but did not flash since it was not stable. So i am going to wait for a new china stable rom to come out whenever it does because in theory it will flash correctly and completely fix the phone because its china miui thats newer than the one global version now i can only wonder if it can flash because i will be going from global to china but again I will let you guys know when i attempt it, I understand I will be waiting a while for a stable version those dont come often but in the meantime i can focus on other things and thankfully i have multiple back up phones. thanks guys
[Xiaomi Mi 8 Questions & Answers] ZhenMing:
Theoretically and my previous experience with Nexus phone, older version of official ROM should be fine as it should get OTA to latest version. So, I think it is worth a try.

At the same time, I'm still patiently waiting for my 1st Mi 8 to arrive at door step.
[Xiaomi Mi 8 Questions & Answers] StarwarsMissionary:
I agree with you and I used to own a nexus too so I understand what your saying but I tried flashing miui 9 china stable and the error said it was an older version and it was "illegal to downgrade" which is weird so I'll just wait for an updated version which might take a while
[Xiaomi Mi 8 Questions & Answers] bassbounce:
Never lock a boatloader with aftermarket global on a China Xiaomi.

I think because of the flashing the bootloader is locked again, maybe try to unlock it with miui unlock.

Maby Xiaomi enable the anti roll back also for the Mi 8 after they did it to the Xiaomi redmi note 5 whyred? Many people have ended up with bricked phones.

Edit

Same problem solution is unlock boatloader

I faced the same problem with my Mi 8 when I locked the bootloader after installing Global ROM. Simply put your phone in Fastboot, and again Unlock the Bootloader using Xiaomi official Unlock tool. Once bootloader was unlocked, phone booted normally with Global ROM.
[Xiaomi Mi 8 Questions & Answers] nairda11:
Hello, I have blocked bootloader and now I am with the bootloader loop.

I've tried to unlock again from console and from the Xiaomi tool, but it has not been possible. The tool says that the device is not associated. Any solution to this?

I have also tried from Recovery (With MiFlash) to put the stable Chinese version, but having a higher version installed does not leave me.

If I re-flash the same version, it completes it but when restarting, the loop returns.

Any solution?
[Xiaomi Mi 8 Questions & Answers] Mramos1985:
Hi I have the same problem but now I have a new and BIG new problem...

When I try to unlock the bootloader with my account the software said me that my account is not bounded in this device... cry cry cry!!!

Somebody knows if it is normal and if I will fixed?

BR
[Xiaomi Mi 8 Questions & Answers] StarwarsMissionary:
The mi unlock tool problems are mainly because of either it's not verified with your account or because before it bricked you forgot to go to development settings and add your phone for unlock which I forgot to so whenever I try to unlock it again it says it isn't verified because I'm a moron and forgot to add my Mi8 to my account in case something like this happened, now I gotta wait for a stable newer miui 9 China version to flash from the adb software
[Xiaomi Mi 8 Questions & Answers] adrii11:
Any news on how to solve the brick?

The perfect solution would be to have access to an account with EDL permissions to re-unlock the bootloader.

When you have any update on this, please let me know I have the same issue and did same mistake.

Let me know if you were able to un-brick it.

Looking fwd to see an update from you.
[Xiaomi Mi 8 Questions & Answers] j1505243:
This. Is. F****d. Up. Someone needs to say it. They do totally crazy things and we saw too many bricks coming from their unexplained tinkering with ARB and locking. Additionally, their each new flagship gets always one step closer to the prices of better competition. We are getting too screwed and we desperately need a new, reasonably priced and logical brand. Nokia? Wouldn't say so. Essential? US only and seems to close down. OnePlus? Getting costlier. Google? Got really costly. **** happened. Really, sorry for OT, but my empathy and sociological thinking just hurts me when I see this.
[Xiaomi Mi 8 Questions & Answers] Jeik:
Yeah, I thought I was the only one thinking like this.

Companies want as much money as possible. Oneplus is increasing prices not because the components cost more but because they waste money on ads and want more profit. And they pull it off because people will still buy their phones.

Honestly, the Mi 8 is a " flagship killer-killer",it provides almost the same stuff as the OP6 for less money but people either never heard of Xiaomi or are hesitant when it comes to buying their phones ( I don't understand why, though ) .

As for their phones dying, I only saw bricks from people who tried tinkering with deep level stuff without actually knowing what they were playing with.

They don't suddenly die/lose basic functions out of the blue like e.g. Moto phones and I don't know of a single device which beats them at this price along with what you get in a phone.
[Xiaomi Mi 8 Questions & Answers] Chema_F:
Just let me tell that you can do the **** even actually knowing what you are playing with. You just need to forget to change the "clean all and lock" option which comes selected by default. And believe me, it's not that difficult at 3 a.m. after some successful flashes.

I think it's not necessary to dive into the hurt, you know.

Cheers
[Xiaomi Mi 8 Questions & Answers] Jeik:
There is a need for that. This is an expensive toy and you shouldn't be playing with it if you are not 100% that you can undo the thing you will do if it goes wrong ( you are free to do it but then at least try to find a solution yourself ) .

After seeing posts which are pretty much like " uwu I made a f*cking boo boo, a weal f*cky wucky, pweese help me guys ;((((( " ( which could've been avoided by following some logic or by actually investigating before flashing stuff ) , it's high time people who are thinking about unlocking the bootloader actually see what they might be getting into if they "touch wrong things in the wrong way".

[Xiaomi Mi 8 Questions & Answers] StarwarsMissionary:
Reading this thread is interesting... I have no updates on the Mi 8 since a MIUI 9 stable isn't out yet I've been using my Mi Mix in the mean time after I got the battery replaced on it. I think most of us who bricked our phone didn't know this would happen. Personally before I flashed and locked my bootloader it was hours after global came out and there was I think only one thread warning about the bootloader lock brick which I did see before hand but they said it was theory? Which it wasn't done yet officially. I should've waited but oh well I didn't but I'm not gonna panic it's sad because I've been doing this rooting and unlocking for years and I've never seen something this stupid and inconvenient before by a company to put into a phone it's really dumb. But now that I know I can avoid it next time especially for xiaomi's next phones that they come out with. Let's keep the thread clean. There should be a stable update soon and I'll release an update on the problem and if I have to resort to hard reset through opening up the phone I will pay a local IT store to do it for me I already have told a guy my situation and he's willing to help if I need it. Anyway ✌️

Thank You
[Xiaomi Mi 8 Questions & Answers] j1505243:
The problem is: official and unofficial informations were too late. Both for ARB and this. We didn't get any info that a common thing to do in MiFlash will result in a brick. I'm not even a Mi 8 user, but just an observer. But what I was about is simple: if they (Xiaomi) were minimally competent, we'd never get bricks by using official methods and software we used from the beginning of time.
[Xiaomi Mi 8 Questions & Answers] Jeik:
Yeah, they should have mentioned introducing ARB in the changelog of updates which introduced it. That's a genuine faceplant from their side. It would be fair to provide free repairs to those devices but a lot of things are unfair nowadays.

But it's not like other manufacturers are any better. All of them have/had some issues, be it software or hardware.

No, the PC automatically detects it in com 20, NO need to open back cover,

The price is 23$ via paypal

Ps. I still have hours left of my 24hours on the mi account, pm me asap if you want to test it out, we could share the 23$ if it worked.

I paid through their website(via paypal), and contacted one of the admin via fb messenger,

[Xiaomi Mi 8 Questions & Answers] Chema_F:
My Mi8 is soft brick and today I accessed edl via testpoint. I tried to flash last China stable ROM but the flashing was stopped with "ERROR: Only nop and sig tag can be received before authentication.". So even no option to use an authorized account.

I can try flashing last China developer ROM but I guess the result will be the same. I hope a Chinese stable miui 10 ROM will make the miracle, who knows.
[Xiaomi Mi 8 Questions & Answers] andrw3:
In my case, my mi8 is giving a recovery error produced when locking the bootloader. When I tried to flash the other day, I tried two roms (global and Chinese). The global one was giving a few errors even in the authorised login... But the Chinese one was fine (I hope I just need an authorised account in order to unbrick it...). This is the rom I'm talking about:

http://en.miui.com/thread-2925471-1-1.html

By the way, while I was looking for the rom I was talking about, I found this:

[Xiaomi Mi 8 Questions & Answers] StarwarsMissionary:
Read the error. Go on China MIUI website and download it from there officially that's what I'm doing rn that link was probably not "official" the error says it could not verify the file and to download from website, I'm about to try it myself so I'll give a report
[Xiaomi Mi 8 Questions & Answers] StarwarsMissionary:
Alright my attempted failed, not sure why getting this weird error I thought it was caused by a server side of things but my guess is that you can't flash from global to China either that or it's something more complexed. Anyway some people int he thread are suggesting s-unlock.com which I browsed on and found the xiaomi edl account stuff for 25$ I went on eBay and bought this https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/132131470654

(Edl cable) and will be trying this without opening the back up if anyone knows how to specifically do all this or has done it to put it in the thread as a guide and we'll make sure to thank the post so people know exactly why it was thanked. Shouldn't take long for my edl cable to get here about less than a week so I'll be doing research in the meantime. Cheers

Hi,

I'll try to buy the edl account from here.

But can you please help with the steps on how to flash China stable rom with edl mode.

At which step do we need to enter authorized account.

With MiFlash tool, it never asks for account details, just gives error: "Erase boot error".

Please help with steps.

---------- Post added at 03:25 AM ---------- Previous post was at 03:18 AM ----------

I have the deep flash cable and already tried with it many times, with no luck. Not sure where I'm doing it incorrectly.

But I think Xiaomi has stopped flashing with deep flash cable for new phones. It works on old phones tho.

Still I would need proper step by step process in order to flash via edl.

How to reach to edl mode.

Might buy an account via s-unlock.

---------- Post added at 03:31 AM ---------- Previous post was at 03:25 AM ----------

Hope you got the same error. ? :D

Btw, what are other ways to download the file unofficially :p

There's only one site from official miui which I mentioned above as well, from where we all generally download rom.

Anyways I hope you understood what I mean. But nevertheless, it was a nice try to flash it.

---------- Post added at 06:22 AM ---------- Previous post was at 06:20 AM ----------

It gives error: "erase boot error", when flashing through the MiFlash Tool.
[Xiaomi Mi 8 Questions & Answers] Chema_F:
The brick can be hard or soft.

With hard brick the device only boots in edl mode so it should be shown in pc device manager as PORT COM once connected. Then one has to start the flash in MiFlash Tool and after few seconds an edl authentication error is shown and a pop-up window requires for ID and password. Once authenticated the flashing process goes on normally and finally if everything is fine the typical 'success' label appears. Then just the normal boot.

With the soft brick you only can enter edl via testpoint. Remove the back cover, remove the battery socket, remove 7 or 8 screws to remove a cover, connect the two points and plug in the usb-c cable. Then the device is shown in device manager as PORT COM and everything goes on as described before.

Another Spanish guy did the job using the latest official MiFlash Tool with success, but it didn't worked for me not asking for credentials (maybe due to the firewall, I don't know). I used a portable version of MiFlash Tool and everything perfect.

Sorry for my ****ty English. I hope this info will be useful for you .

PS The other guy flashed latest China stable ROM 9.6.7 and I flashed the previous 9.5.11.0 So I think it doesn't matter the version.

PS2 If your device is brick you can only flash in edl.

PS3 You'll only be asked for the credentials in edl mode
[Xiaomi Mi 8 Questions & Answers] arunkareer:
Thanks alot descarao81,

I think this resolves a lot of my doubts. Which means, my device is Soft Bricked as I cannot see COM Port connected in Device Manager once in FastBoot mode (with Bunny Image).

Can Deep Flash Cable help reach EDL Mode, without opening the back cover. Coz I already have the Deep Flash Cable, was wondering if there is a way to reach it with this cable.

Otherwise, in order to reach to EDL Mode, I have to open the back cover, which can be a task here. I will check today evening, if i could reach EDL mode with Test Point and then if i could get Mi Authorized Account.

If someone still has access to Mi Authorized account, please share, i am willing to share the price as well.
