Ok guys here is the step by step even for noobs how to unbrick Xiaomi Mi Max (helium).

If you have access to fastboot jump to step 11

Requirements :

* MiFlash Beta :Download Here

* MiFlash 20151028 : Download Here

* Global Fastboot Rom : Download Here

* Xiaomi Qualcomm Drivers
* Screw and tools.
* Paper clip or cable
* For sure Usb Cable.

Now if you all ready lets continue repair. First of all you need to open back cover.

1) Open Back cover and disconnect fingerprint sensor and battery. Dont connect battery till you finish whole process. (How to disassemble video : https://www.youtube.com/watch?v=YMG04GqVU_0&t=64s)

2) Make a paper clip to setup short circuit in your mainboard. Here are the testpoints. https://s15.postimg.org/s0j0qhq3v/Xi...est_Points.png

3) Ok here is the hardest and trickiest one. While you are holding paper clip or cable with those testpoint you need to connect phone to pc. My suggestion 1st connect usb cable to phone then make short circuit then connect to pc.

* One more time you need to connect phone to pc while those two testpoints connected to eachother with a paperclip or a cable.

4) Here is the second tricky part. Unzip rom file. Important part is the name of folder. Please try to make it as short as possible.
Ex : C:\mimax\

So after extraction your folder will looks like this : http://oi63.tinypic.com/334rr11.jpg

5) You need to install both MiFlash versions. They are 2 different software so you shouldnt see any errors like "it is already installed".

6) Go To C:\XiaoMi\XiaoMiFlash and run XiaoMiFlash.exe as an administrator. Click browse and choose your rom folder. NOT IMAGES FOLDER ROM FOLDER !!!! ( Ex : C:\mimax)

7) Click "refresh" you will see COM port and click "flash" If you dont see any COM port here first check if you installed drivers correctly. If drivers are installed correct please go back to step 3 and try again.

8) Install will start and continue and %99 possibly it will stop in the middle You will receive Max buffer 256 error. No worries just keep calm and take deep breath. Go to next step

9) Disconnect usb cable from pc and phone. Reconnect battery. Now voila phone will ready to work BUT NOT READY TO WORK FLAWLESS. So now put your phone to fastboot mode. Yes you read correct now your phone will be in fastboot mode even it could be ready to use but just wait for next step.

10) Fastboot mode : Volume Down + Power button you will see fastboot screen and connect to PC.

11) Now close old MiFlash and run the normal one from either desktop or C:\Program Files (x86)\Xiaomi\MiPhone\MiFlash.exe or C:\Program Files\Xiaomi\MiPhone\MiFlash.exe.

12) Choose your rom folder. NOT IMAGES FOLDER ROM FOLDER !!!! ( Ex : C:\mimax).

13) Click "refresh" and this time you have to see device serial number on device tab. Now click flash and let process finish. It takes around 3-5 minute and phone will reboot by itself.

Now re-assemble your phone. DONT FORGET TO CONNECT FINGERPRINT SENSOR. Now you are totally ready.

Tried 5 times with my very own Xiaomi Mi Max 128 GB.

Different reactions
Hi,

My device could still boot on fastboot mode, and flashes successfully through it on MiFlash Beta. However, the device remains stuck on Mi logo. I've already tested flashing on EDL mode apparently successfully, with the same results. I've flashed TWRP, but the device don't enter recovery mode. What can I do? Any suggestion will be welcome.

This is why XDA is a great FORUM! Thank you for writing this thorough solution!
My device is up and running currently with MIUI 8! It went from a dead brick to a productive device again! I was almost giving up hope! You saved the day! It was a lot of work, but it is great seeing the device alive again.

I would just add that taking the cover off doesn't even need a tool like in the original disassembly youtube video: https://www.youtube.com/watch?v=dULcMWCEgEc

Yay!

Hi @SubwayChamp Everything I did was in the post and video from above in the first post by benz....

His instructions were perfect along with the youtube video. It's tricky, true, but with patience you can go through the steps and get your device running again. I was so glad that @Qulox gave me this link to this thread.

As you go through the steps, if you get stuck, we can try to give you advice.

I have two dead mi max. One 128gb helium and one 32gb hydrogen.

128gb helium is completely lifeless. No charging led, no vibrations, no fastboot mode. Though i could bring it up to edl mode showing right qualcomm device in device manager. I tried flashing stock rom as mentioned in this guide which rather went successful without giving any error, even while battery connector was removed.

But mobile is still in same lifeless condition. Other than flashing process going through, it didnt make any difference. Dont know whats wrong. Also i didnt have to use two miflash versions as mentioned in steps as flashing process didnt give any error.

32gb hydrogen, boots up in flashboot mode, shows charging led, mi logo even edl model worked without any issue. It even boots up, but gives error of encryption unsuccessful asking me to reset device. I tried factory reseting it. Tried flashing twrp and wiping, formatting data, changing file system to all formats like fat, f2fs, ext1, ext2, ext3, ext4. Tried flashing crdoid and RR based on orea. Nothing working.

With twrp it keeps bootlooping showing mi logo. And with stock rom, recovery shows up encryption error. Followed procedure mentioned in this guide as well.


Is there anything am i missing or can do? Btw, bootloader is locked for both the devices. I could flash twrp referring another guide which suggested to replace stock recovery in rom files/ folder and flashing it like stock rom through miflash tool.

Battery problems? in the 128 especially?

If "nothing works" through any normal software methods, the ram &/or ROM memory chips might have become semi-defect. They are not eternal . . .
