xiaomi mi3 hard brick cold dead?

Lately I was flashing mi3 trough fastboot on w7ulti64bit when something went wrong and now its cold dead.
I have been looking for solution everywhere and as usual xda is my last resort for help with phones, usually I found here what I was looking for but this time it is first time when I have to post new threat.
So basically I found that battery controller had some cold soldier on chip, whole module gives 0v while cell itself 2,8v so I think I fixed it since now whole battery module shows 3.3v and cell itself 3.8v after charging.
But im unable to wake up phone in to fastboot or any other way to reflash it.
When connected to 2000mAh charger there is solid red light, when connected to PC it lit for a second then goes off and PC recognizes mi3 as USB input device and HID compliant device.
I have tried to update drivers for those devises so miflash would recognize it and allow to flash it but without any success.
Any idea what else I could do with it, or how to force flash to flash at least boot sector?

Try mi flash tool

Main problem is that I have tried all 3 miflash I could found 2.11.6 20131108 20140509 and none of them recognizes device and I can't even initiate flashing process ;/

it sounds like a driver issue. just download all the drivers you can find for your phone.

r u following correct procedure for using MI flash tool ?
is ur Phone able to boot to FLash mode ( turn phone off > Press volume + Key then Press Power on - it will show flash mode )
Now Open MI Flash tool > Press Refesh > it will show phone now ( a number will b shown instead of name Xiamo Mi3)
Now Extract Fastboot rom to C Drive ( it should look like this C:\ROM (Location should not cointain space)
Now click Browse > advance > select C:\ROM\Folder\ select bat file

Its not drivers issue since its get detected as QUALCOMM HS-USB QDLoader 9008 or QUALCOMM HS-USB Diagnostic 9006 depending of its state.
In QDLoader it is recognized by miflash as COM20 device and I can upload by miflash or qpst boot image, then it switches to diagnostic that is recognized by some sort of string and I can upload/proceed with rest of rom flashing that includes creating partitions and writing data to them.
Main problem is that when its successfully flashed it is still cold dark, while PC can see it and all partitions like 28 of them...
And I think its related to the fact that qpst reports phone as in download mode.
Any idea how to exit that mode, like in Mi2 that was forced to enter "service" by shortening some pins to put it download mode to flash cold dead ones?

You were already looking at it
Kinda wasted a lot of Mine and Yours time and some of my money
If You got any other ideas since that time how to resurrect it just let me know.

Any solution?
Is there any solution to this problem? My phone has been cold brick for 3 days now. Doesnt boot up or charge up. Detected on connecting to PC with a sound, but Shows as Com 10 or 20 on Miflash and thus cannot be flashed.
Cannot boot into fastboot as well.
Anyone anything?

Is there anything I can do? Brick help

My Xiaomi mi5 does not turn on.
No lights, fastboot is not accessible, resetting it does not do anything.
Basically for any combination of buttons that I press, nothing happens and the screen stays black - it is completely dead.
However, when I plug it into my pc, the devices shows up as qualcomm hs-usb qdloader 9008 (COM3) which is the only sign of life from the phone.
What I want to know is if it is possible for me to unbrick the phone from this situation. I understand that I need to get into fastboot in order to flash the ROM, but is there a way to get to fastboot using my pc? Or even turn the phone on with commands? At the moment ADB and Fastboot does not recognise my phone, is there a way to make it detect it from the state it is in?
Thanks

Do you have all the necessary driver installed? I think yes and that is why you are seeing in (COM3) port. You can do one thing, Unplug the phone from PC and Press and Hold Vol Down (-) and plug in again. If not works then you can also Press and HOLD Vol Down and Press and HOLD Power button until you see Fast boot menu. If don't work then try the same thing with Vol UP button. Then you suppose to see a MI phone logo with a USB cable.

"qualcomm hs-usb qdloader 9008" Is a signal of Hard Brick for QCOM devices (Like for LG G2);
http://forum.xda-developers.com/lg-g2/general/fix-unbrick-lg-g2-stuck-qualcomm-hs-usb-t2933830
As you can see here, for fix it you need all partition files, all system files, and a programm
But i dont know if it will works also on SD820, you might need all files for Mi5
Just a question: How did you bricked your phone?
EDIT:
I had an idea: maybe inside fastboot rom you can find all files you need, it might be worth a try, at least you can send it to your shop where you bought it

1: if you're detecting it as qcom 9008, there's a good chance it's in EDL mode, which is good news
2: download MiFlash from here: https://www.androidfilehost.com/?fid=24521665358595574
3: download the latest dev rom from here: http://update.miui.com/updates/v1/fullromdownload.php?d=gemini&b=X&r=cn&n=
4: Extract the files to C:\
5: Open MiFlash & point the folder to the root ROM folder, example: C:\gemini_foo_bar, NOT C:\gemini_foo_bar\images
6: connect your phone & select flash all (1st option from the left, bottom of MiFlash tool)
This might take a few tries (example - you might receive "missed hello packets)
Once you're done, you can stay with the China Dev, unlock the bootloader & flash a xiaomi.eu rom, or CM.
Good luck.

I also had the same issue with black screen and no responses from vol. & power buttons. But when I notice that in device manger it showed the qcom driver, then I new that there was hope to recover the phone. I can confirm that this will unbrick your phone. I MiFlash'd the China Rom (non-dev), unlocked the bootloader, MiFlash'd MiFlash_xiaomi.eu_gemini_V7.2.13.0.MAACNDB_6.0 rom, sideload lastest stable EU rom, TRWP and SuperSU.

Thanks for the guide, 1 q tho: what to do when i get the "missed hello packets, try to recover" message?, wait or restart the process?
Ok, solved by disabling driver sign (press F8 during boot)

Hello , i got the same problem as described at this topic and here is my problems :
I can't turn on my phone and i can't put it in fastboot mode ( tryed a lot of buttons combinations)
But when i plug it into my pc - it recognizes as Android
I have tryed to install drivers but windows shows mistake and can't install that
When my device connected to pc and i press volume + and power buttons - in few minutes system(WIN 10) recognizes it as ADB interface(can't install drivers too) and i have acess to mi5 internal storage ( i can download photos and so on )
But mi flash doesn't see phone in any mode and i feel that my device is still alive and i can recover it but don't know how....
I will be grateful for any help !

If you can see it in adb, you might be able to see it in fastboot.
Try go in to fastboot (even though you can't see it on screen.)
And try fastboot oem device-info see if you can get anything. Then we go from there.

same issue
I've been having the same problem with my MI5, 128gb running MIUI8 6.6.23CN, unlocked bootloader
It started when I did an OTA from 6.6.16, then OTA failed, I tried again this time it downloaded full rom and went into my twrp but installation started automatically. Then it rebooted but the system stayed in black screen. I forced-rebooted it, then everything was fine and I was on 6.6.23. I was using the phone normally for a few hours, then around 6hr later after I upgraded, I took phone out of my bag and it was bricked. I tried everything, no fastboot, no adb, no recovery, no led, nothing on screen. MiFlash reconizes (cuz of the 9008 status) but flash fails. I event opened it up, disconnected the 3 cables from the battery and hold onto power buttons for few seconds to try to drain whatever power it has left in system. Reconnected battery but no change.
I gave up, put phone back in case and was going to ask friend to take it back to send to china for repair the next day, but then I too it out an hour before I go meet my friend and suddenly, phone led flashed red and I see on screen out-of-battery icon. I plugged it in to charge then LED flickered quickly in red for a bit then turn solid red, then turned orange. I let it charged for 10min or so, and pressed power+Vol_Down for few seconds. Lo and behold, I got the bunny on screen and went into fastboot. I was able to re-flash 6.6.23 and phone was good to go again. (but why did removing battery cables do the same thing? Maybe I didn’t leave it disconnected long enough?)
Good story until this part… then 2 days later, I wanted to test MI Talk with friend, I click on it, and phone froze. Both touch sensor light stayed on. I waited about 15 second and forced reboot. Phone vibrates once and then went into hard brick again. Exactly same situation, nothing works.
Now I am waitng for phone to discharge by itself. God knows how many days it will take. It was 96% charged. (1st time I had about 45% and too a day to discharge)
Only if I can get back into fastboot......

how do you flash stock recovery if you dont need to go into fastboot? now I am unable to go into recovery or fastboot as the phone does not boot at all. connecting it to PC reconizes the phone as the infamous "Qualcomm HS-USB QDLoader 9008" device.
Its been 4 days and the damn battery hasnt run out yet as I can still plug into pc and get qualcom 9008 to come up. I think I am going to send to china to get it fixed properly if I still cannot get the red flicker of low battery power to come up by tomorrow.

It has happened to me 3-4 times already. It didnt want to boot. No signs of life either. I even sent a message to the shop for sending it back..the only thing that was telling me it wasn't completely dead, was the qualcomm driver ,while on USB connection with the PC, which you are referring to as well
Here is what you could try doing. Try pressing the power button for about 30 seconds at first. If it does not boot, try bending the phone real gently back and forth (don't break it!!). Preferably, hit it gently with your palm while holding it in your other hand.( -- I know it might sound weird --) I noticed that it's shutting down while i have it in my pocket and doing some work which squeezes the phone a bit against my leg.
I came to the conclusion that some connection must become loose when some pressure is being applied to it.. Unfortunately it has to be a design flaw of the phone. Nothing random with yours or mine , in my opinion. // I have a case and tempered glass installed as well since the first minute I got it in my hands..

Thanks for the tips Takkaros. I tried what you said but nothing changed (though I was a bit scared to bend it too hard). 1st time it happened to me, I had around 40-50% battery and somehow battery completely drained 24hr later so I got the red blinking low of battery light and was able to charge the phone up and go back into fastboot, which solved everything. this time it happened when I had 96% battery(which I knew cuz I was using the phone, then clicked MI Talk and phone froze, then bricked). I wish there is a way for me to force a battery drain without opening it up. I did opened it up once(on the 1st brick) and disconnected the 3 battery cables, but it was still in brick state when I put everything back.
The qualcomm 9008 driver detection was also my concern about sending back the phone. Chances are by the time my phone reaches the repair shop, battery is completely dead and they simply charge the battery then flash a stable rom and send it back to me without changing out the motherboard or whatever. Which in such case it will be faster for me to just wait a week or two and do myself, instead of shipping it to china and wasting shipping cost and probably will take 4-6 weeks.

I am not sure whats wrong with this phone. Sometimes it turns off while i have in on charge at night, with the Green led lighting. I can get into recovery mode but all the partitions are missing. I cant wipe anything and all my files are not there. If I restart the recovery 2-3 times everything comes back to normal. Maybe there is something wrong with the flash drive. If honorbuy replied to my messages i'd sent it back to them asap. This is not a reliable phone for daily use

Try using mi flash. Follow the instruction

I am sending back the phone to china to have them "fix" it. Not sure what they will do, hopefully they either swap me a new phone or swap out the motherboard or something. I just hope they dont just boot into fastboot (after battery completely drained and system resets) and flash new rom and send it back to me.
Probably will take a month or so. Good thing i still have my old phone.

This happened to me recently. I used mi flash and the global 7.2.4 stable fastboot rom to get it going again. Wouldn't work for me with with with newer versions. Think edl has been disabled on them.

I know it's been a long while since you had this problem, but as I have to face it myself without any clue how to solve it I thought it was a good idea to recover this thread.
First of all, let me say it happened to me with a Xiaomi mi5s. I had already installed adb & fastboot, as well as Xiaomi drivers from the Xiaomi Unlock Tool.
The problem arose when I made a partial firmware upgrade through fastboot in order to install LOS 14.1 via TWRP. I could not geet into fastboot mode, the screen went completely black and no charging LED. Curiously my laptop (Win10) made a tiny nose everytime I pluged or unplugged it (the same one it does everytime you plug a new device) and saw that it recognised it as a 'Qualcomm HS-USB qloader 9008'. More curiously, Xiaomi Flash Tool (BTW, it was the beta version although I guess the latest version would have worked as well) recognised the device although everytime I tried to flash an official firmware I got a message error: 'cannot receive hello packet'.
Well, after some research I was scared because I didn't want to open the phone to unplug the battery or anything. But I read somewhere that someone had the same problem as me and that he tried Xiaomi Flash Tool until it worked.
That was it, that was the clue. Xiaomi Flash Tool ready, having initially recognised my mi5s, the phone connected to the laptop, I made the combination to get into fastboot (holding volume - & power button) until my laptop made a tiny nose (the same one I explained at the beginning). As soon as I heard it I left the phone and clicked on the flash button on Xiaomi Flash Tool. Yes, it worked out. I installed latest development chinese MIUI rom. From there, I got into fastboot, flashed a new recovery... Well that's another history, the fact is that the mi5s is working again and I must say I feel really relived.
If anyone encounters the same problem I had I hope this post is of any help to him/her.

Xiaomi mi 8 hard brick!

hello, i have hard brick at my mi8 .
When i try to press the power button the phone doesn't boot, If i try to go into recovery mode it doesn't boot and same for fastboot mode.
The screen is unresponsive (no backlight) and it doesn't vibrate. When i connect the phone to my computer it is automatically recognized as Qualcomm HS-USB QDLoader 9008 (COM5) which correspond to the EDL mode (i think).
When try to flash any rom with miflash i get the error " cannot receive hello packet.
Can anyone help me ?:crying:

Likely you have too much power coming from your usb ports, use a usb hub such as this: https://www.amazon.com/BYEASY-Porta...jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
Now try Mi Flash again, make sure that the lock bootloader (which is checked by default) is unchecked.
Now it should work, be sure that you are using a fastboot rom and not a recovery rom. ( a recovery rom will not work)
Make sure that it is a fast boot for your device : If you have a global device here is a link with quite a few fastboot roms :https://c.mi.com/thread-1899815-1-0.html
If you still have trouble let me know, and tell me specifically how you arrived at your brick, I helped someone with this exact issue a couple of weeks ago, and I was going to link you to that thread. But i can't find it at the moment.

I get the same error " cannot receive hello packet" with hub USB.
MY xioami mi 8 is global version, i unlock the bootloader and make a downgrade with twrp to a older version of stable rom, and when the phone start ,its all ok and login my mi account, and the phone goes down and never more boot. Always in the pc i get qualcom port (edl mode) . Sorry for my bad english.:crying:

I think i need account with EDL authorization to flash any rom. And i can't found anyone to save me..

Try https://forum.xda-developers.com/mi-8/how-to/unbrick-mi8-edl-authorized-account-t3896677

Thank you .. i try this metod but no success

I dont have his name but one of the techs from this site is a frequent XDA user and supposedly legit.
In the end there is a risk of losing $12. Seems to be worth $12 to me.

Asus Rog Phone 3 Uber hard brick

Hi Guys,
I really need help with this one. I have tried almost everything.
Here is my problem.
I have an Rog phone 3 strix edition QUALCOMM based.
I repaired the screen because i dropped the phone.
Everything was fine working well. Me with my big head decided to do an factory reset to wipe everything clean from the phone and then the problem started.
The phone was restarting every time i plugged in a usb c cable. If i wanted to listen to some music on headset wont work because it will end in a bootloop.
Now the phone is stuck in CSC Fastboot mode and PC wont recognized it. The screen will turn on and send me to CSC fastboot but that's it. I can turn it back off.
Can i Revive the phone or is it food for the recycling bin?
Please Help.
Sincerely,
Ayolyas

With some effort you should be able to get back on track - unless it's hardware related to the display change you've done.
Can you do a reboot to bootloader from the boot menu? If you can confirm if you have fastboot access. If you do, RAW flash the device.
Worst case, you force the device into EDL mode and do a flash from there, but leave at as the last option.
If the relpaced display is causing harware issues, that's a bigger problem...

Hi Andrologic,
I cannot reboot to the bootloader. I am stuck in csc fastboot. I was trying to put it in edl mode i even bought an edl cable. But i have no idea how to use it or how to put the phone in edl.
I went back to the repair shop but the phone was working fine when it left the phone shop. The problem started when i decided to go for factory reset.

So, when you turn on the device, it falls into CSC FB and you can't navigate anywhere at all from there?
What happens if you try to do a RAW flash from CSC FB?
Flashing it in EDL mode may otherwise be the only option. Power off the device completely. Then hold Vol up+down pressed and connect to the USB side port. You should land with a completely black screen and on your pc see the device identified in 9008 mode - that's EDL. Since you have a flash cable, you can obviously use that too.
Remember you need Qualcom drivers installed to work in EDL mode. There is a guide with steps for EDL flashing somewhere here on the forum. All the steps are explained.

I cannot navigate anywhere from csc. If i try to reboot bootloader i will end in the same place.
I try to connect like you told me Vol up + down but i ended up at the same place. An raw flash from csc fb how do i do that?
And the steps for edl if you can help where to find those steps because my google history is full off items and still no luck finding the right one.

Yes, you have flash cable, so getting into EDL shouldn't be an issue any way.
This is a useful video on how to use your flash cable to force the device to EDL:
Just remember you need QCom drivers installed to flash in EDL mode, the normal drivers won't do it in EDL.
What is the device identified as on your PC when in CSC FB? Can you send any FB commands to the device at all? Does 'Fastboot Devices' return your device id? If so, try first to do a RAW flash from the Fastboot state you are stuck at. You don't really want to mess with EDL if you can avoid it. Download one of the RAW rom's from the links here on the forum. Version number doesn't matter as long as it matches with your device version, i.e. WW assuming you're on Global.

Hi,
Nope. I can get into EDL mode so i think it is hardware related. You can say it is fresh for the garbage.

Hope you did the proper way of entering edl mode. btw you can still send that to service center. but first try some other way as your phone still boot
