Bootloop Mi Logo, only fastboot available - Xiaomi Redmi 2 Questions & Answers

After a restart this morning I am in a bootloop. Only thing I'm able to enter stable is fastboot.
Tried to flash the stock fastboot rom but MiFlash and manually is giving me an error when trying to write the partition.
fastboot flash partition gpt_both0.bin
target reported max download size of 268435456 bytes
sending 'partition' (33 KB)...
OKAY [ 0.006s]
writing 'partition'...
FAILED (remote: failed to write partition)
If I flash TWRP through fastboot I can't enter it with volume up. If I use the bat version to flash TWRP, it restarts with TWRP but after a few seconds in TWRP it reboots into the bootloop.
Anyone any clue before I have to send my phone back to China :/

Use Mi Flash Tool - Install stock recovery
Its a common issue while using Custom recovery. so, to get life to your mobile you have to install stock recovery.
(search google if you cant able to find, because of xda limitation on New Users i cant post any external link here. Sorry!)
Step 1: Download MiFlash Tool & download your fastboot rom.
Step 2: Turn off the device. Press the Volume– key and the Power button at the same time to enter Fastboot mode. Then connect the device to the Windows PC/laptop via a micro USB cable
Step 3: Double click on the downloaded ROM file to decompress it. Open the file folder for the decompressed ROM pack, and copy its path on the computer.
Step 4: Decompress the MIUI ROM flashing tool downloaded in Step 1, and double click on it to install (if there is security warning, select 'Run'). After installation is completed, open MiFlash.exe and paste into the address bar the ROM file folder path copied in the last step.
Click on the first button (circled out in yellow) to Refresh, and MiFlash should automatically recognize the device. Then click the second button (circled out in red) to flash the ROM file to the device.
Step 5: Wait until the progress bar inside MiFlash turns fully green, which means the ROM has been successfully installed. Then your device should automatically boot to the new version.
Step 6: Wait till the phone boot up - at first it may take more than 5 Min.Be patient with it,
Note: Using MiFlash Tool :
At first try to flash without losing data, if doesn't helps, then select Flash All. (for my Redmi 2 prime it worked with flash all). If any error let me know in comment section.:good::good:

Thanks for your suggestion kalachar.
MiFlash is giving me the same error though.
0x8000405: FAILED (remote:failed to write partition)
I managed to enter TWRP once without it rebooting, I checked everything and the problem seems to be nothing from internal memory can be mounted.
I could only mount persist and modem.

Try Full format,
Wipe>Format>type "Yes"
wait for it to complete and then reboot
if the problem still,try flash in Mi flash,.
Hope it useful,.

nothing happen after applying this method

Redmi 3 Pro Considerations - Flash global ROM with BOOTLOADER LOCKED

I've tried some things on my Xiaomi Redmi 3 Pro and I want to share them if helpful for someone.
I've done all this with Xiaomi.eu Rom and SMIUI
///// I'm not accountable for any problem on your phone, do it at your own risk! \\\\\​
1 - Button combinations (unplugged from pc):
vol+ & vol- & power = force shutdown if in fastboot or download mode, if powered-on it's a restart
vol- & power = from switched-off phone goes in fastboot (from there you can launch another combination: vol+&vol- while launche cmd: fastboot.exe reboot)
vol+ & power = preload\ bootload mode (the yellow screen where to choose recovery\ fastboot\ download mode)
2 - For any type of problem \brick \ bootloop be sure before about this:
A) if you run the phone in fastboot mode, check if you can see it in fastboot command line from pc (cmd: fastboot devices)
B) if you run the phone in download mode, check if you can see it from miflash
If these point are ok this means the pc is ready to see the phone if you softbrick it or it goes in bootloop.
You will be always able to run it in fastboot mode, then download mode, an flash any rom to the phone that works.
3 - What you need?
Install last version of MiFlash, here a guide: http://en.miui.com/thread-272376-1-1.html
Install MiPCSuite in english, here the link: http://pcsuite.mi.com/
If you have problems with ADB, install ADB drivers, here the link: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118 or http://forum.xda-developers.com/showthread.php?t=2317790

Download TWRP 3.0.2.0 for MiFlash: https://mega.nz/#!cF4VVQiY!zrq2DTQRBX3UHRPOXN1dDNWiTn5tnoPxUfrHF_Rsnq4
Download ROM from different links:
http://en.miui.com/a-234.html (miui china stock, BL Locked)
https://www.androidfilehost.com/?w=files&flid=36337 (Xiaomi.eu with Gapps, no Bloatware, BL unlocked)
http://smiui.net/kitchen.php(Xiaomi.eu + other stuff)
Install Notepad++
4 - Prepare ROM:
As suggested by the user Jack0190 there are ROMS where is not needed to mod this files, like for "Xiaomi redmi3 pro locked multilanguage" roms.
Searching on web you can find them quickly, just be aware that there are some roms that have problems with SIM recognize. This comes from an old Thai \ Indian MIUI.
I've seen first this thread on en.miui, http://en.miui.com/thread-276565-1-1.html , where explains how to modify ROM to change the bootloader check. The guide explains very good how to modify the "boot.img" file of roms.
So just follow those steps.
I've seen that you can do it for both types of rom, for Recovery and MiFlash too.
For the recovery ROM, you have a file to open in 7Zip, copy the "boot.img" from it, modify it as explained in the guide, and re-copy in the zip file again.
While for the one for Miflash, it's easier; extract the rom, copy the "boot.img" file from \image folder, modify it with, and change it in the original folder. Then flash it with Miflash.
5 - Connect phone in Fastboot with pc:
One thing that always will save you is the ability to connect phone in fastboot mode.
Before start the phone in fastboot mode with cable unplugged (point 1).
Once you've installed Miflash, go on it's directory folder (C:\Program Files\Xiaomi\MiPhone\), and run cmd from there (shift+right mouse click).
Connect phone to pc.
Then run command "fastboot.exe devices" and if the result under the line on left is a code, the phone is recognized
6 - Force Download Mode from fastboot:
To force the phone to go in dowload mode, first run it in fastboot (point 5), check if it's recognized (point 2-A), then type but don't run command "fastboot.exe reboot".
Now push vol+ & vol- in the same time, and now run the command.
If it runs in the right mode, you can see it's connected by device manager under "Ports (COM &LPT)" section.
You will see "qdloader 9008 driver" with a COM port installed. The same port you will see in Miflash if you run it and push the "refresh button".
7 - Flash Job:
A) First you need to flash the recovery, TWRP, and to do this you should already have done this things:
Install Miflash, MiPcSuit
Your phone is right seen in fastboot and in Miflash in download mode.
You have downloaded the right versione of TWRP for MiFlash.
B) Flash TWRP with Miflash
Select in Miflash the button "Browse" and go to the folder "\Image"where you have extracted the TWRP zip
Click "Refresh"
Click "Flash"
Wait to complete (If it fails sending hello packets, it's because it's too much time the phone is in download mode, in this case, switch it off, e restart in Download mode and re-do all )
C) Copy modified ROM:
Now, I've done this step by OTG connection but there are more ways to do it:
Connec and mount an USB Drive in OTG
Push it by ADB
Copy it by SD card
If the old ROM still works, copy it in MTP connection
if none of this options is available, flash the Rom with Miflash, flash again TWRP recovery, run recovery, wipe cache and dalvik (factory reset option under "Wipe") and try to run system, it should run last system flashed.
D) Flash modified rom by recovery
E) Restart in system (It could take long time, even 10 minutes, so just wait for it)
Thanks to all users\ people helped me with different guides from XDA and other forums.
I' m sorry for no image, but it's not an official guide.
If something is wrong I'll change it asap, but don't blame me, these are just advices.
If it's not enough clear, search it on web.
If there are grammar errors, the Image verification confirms "I'm not a robot"
If you don't find the answer, then it's 42.
After mod, i can flash rom update from recovery?
Inviato dal mio GT-I9505 utilizzando Tapatalk
Just wanted to say thank you - This guide works. I tried it with a new redmi 3 pro with locked bootloader. You can skip step 4 if you want to, because there are some prepared images available (search for "xiaomi redmi3 pro locked multilanguage" and you will find them).
Also to note: The first boot of the new system took some long time (~ 10-minutes), so don't get frustrated. As long as there's the android logo with the three dots wandering around, everything should work fine.

not sure about this, I've flashed the last version available, so i don't have updates for now to test.
But i think that it could overwrite files modified.
This is what in some guides tells.

Thanks to you, I've updated with what told. I've tried some of ROMs for locked bootloader, but was an Indian \ Thai version, and I had issues with SIM, no recognize.
That's why it was needed for me to use other rom for unlocked bootloader.
Hi, thanks for the guide. It seems like it'd be the only decent I could come across for my problem.
The only thing is that everytime I try to flash any ROM/image through MiFlash, I get the error:
Code:
Error loading type libary/DLL.(0x80029c4a: wait port ready to use <time in seconds>)
So far I haven't found anything or anyone that could help me with this. Can any of you help me out here? That'd be much appreciated.
Thanks~

::Edit::
Alright, turns out I just had to do this:
1. Uninstall the Qualcomm drivers
2. Reboot Windows into "test mode"/Disabled driver signature enforcement
3. Reinstall the Qualcomm drivers
4. Flash device (phone in download mode)
5. Be very pacient. Waiting through the phone's boot phase
(took about 10 minutes; if it takes more than 15 minutes, then something is probably wrong. Try to enter download mode and flash it again.)
6. Redmi 3 working again
Okay, so, this worked for me, it doesn't mean it'll necessarily work for you!
This was done with a locked bootloader and MiFlash 2015.10.28.0

(Working Method, Latest MIUI 8) - Unlock bootloader + twrp recovery + install SuperSu

How to Unlock bootloader + flash twrp recovery + root and install SuperSu in Xiaomi Redmi Note 3 (Snapdragon) without waiting for permission on the Latest MIUI 8 - V8.0.6.0.LHOMIDG. (as of 22-11-16)
Here you have the step by step procedures to successfully unlock your Redmi Note 3 SnapDragon global variant with latest global stable rom MIUI 8. Please follow the steps carefully.
The rom used for this procedure is the latest global stable fastboot rom MIUI V8.0.6.0.LHOMIDG.
This is the working guide for the Xiaomi redmi note 3 (SD) on latest MIUI 8.0.6.0 as on 22-11-2016. I did lots of experiments, bricked my device several times to find this working guide for latest rom, however you are free to link to this page for reference.
You dont need to apply for official unlocking and wait for a month or more to get the sms confirmation from xiaomi to officially unlock the bootloader, the problem with the official method is many users have reported that they did not receive the confirmation sms from xiaomi, even if they receive the confirmation sms the unlocking process stucks at some percentage and fails to unlock the bootloader.

FOLLOW THE STEPS CAREFULLY, IF YOU FACE ANY TROUBLE, START OVER AGAIN FROM STEP 1, IF YOU FACE ANY OTHER ERROR OR BOOTLOOP OR STUCK IN LOGO LOOK AT THE TROUBLE SHOOT SECTION AT THE BOTTOM.
Step 1:
Enable Usb Debugging, if not done before:
Open Settings in your device"Redmi note 3 (SD)", scroll to bottom in settings and click on "About phone" and now tap on MIUI version 7 times, it will show a message like "You are now a developer" and Developer options will be revealed.

Note: After that when you connect your phone to the Pc to execute adb commands, a prompt may appear on your phone with computer's fingerprint key, you should confirm it when it appears. In case if you already done this for your computer with proper adb drivers installed, you don't need to bother about this.
Step 2:
DISABLE DRIVER SIGNATURE ENFORCEMENT IN YOUR PC:
You now have to disable driver signature enforcement in your PC, to do this you have to open the settings window by pressing the shortcuts"Windows button + i -> Update & Security -> Recovery -> Advanced startup -> Restart now. Now the system will logout and show Recovery options, from there select Troubleshoot -> Startup Settings in Advanced options -> Restart. Your system will now reboot and show the "Startup settings" screen, a list of options will be available, you have to choose option number 7 to disable driver signature enforcement. Then the system will boot into the OS with driver signature enforcement disabled. After that do not restart your pc until all the below steps are completed, in case if you restart your pc for any reason you need to redo this step again because system reboot might enable driver signature enforcement again. That's it. Refer this video if you need further guidance.
Step 3:
To install ADB, Fastboot and other drivers in your PC:
Install the " minimal_adb_fastboot_v1.4_setup _working " file downloaded from the link I provided above. If any security prompts appear on your screen, allow all prompts.
Install the " MiPcSuiteSetup_v3.2.1.3111_2717.exe " file downloaded from the link I provided above. If any security prompts appear on your screen, allow all prompts.
Install the " MiFLash_v2016.08.30.0.zip " file downloaded from the link I provided above. If any security prompts appear on your screen, allow all prompts.
Step 4:
Extract AnF.zip file and execute the commands:
Now extract the "AnF.zip" file downloaded from the link I provided above. Connect your phone to Pc using the Usb cable. Open the extracted AnF folder and double click on the cmd.exe file, which will open a adb command window from there.
Execute the below command through adb command window to check and confirm the phone is connected via adb interface. If connected properly it should show device serial like "******** device"
adb devices​
Incase if your phone shows a prompt for computer's fingerprint key approval, allow it. Then execute the command again. You should see your phone serial number as shown in the image below, which means your phone is properly connected via adb. Incase if the device is not connect properly via adb, disable and enable USB debugging on your phone. If that also helping to install the phone's adb drivers, extract and run the"ADBdriversetup.zip" downloaded from the link I provided above to install the specific drivers for your phone.
Step 5:
Reboot the phone to EDL mode:
Now you have to reboot your phone to edl mode aka Emergency download mode. To do this execute the below command via adb window with phone still connected to Pc.
adb reboot edl​
Your phone will now reboot into blank screen or edl mode and new driver named "qshusb qloader 9008" will be installed in your Pc, now only red led notification light will be blinking on your phone. Once the driver is installed properly, the phone is now connected in edl mode. Now close the adb command window.
Step 6:
Setup MiFlash Tool & Flash the ROM:
Open the MiFlash tool (MiFLash_v2016.08.30.0.zip) application you installed earlier, click refresh button and your phone will be visible as port number (ex: COM10) in MiFlash tool. Exe file is in this path,"C:\Xiaomi\XiaoMiFlash"
Now extract the "kenzo_global_images_V8.0.6.0.LHOMIDG PreRooted by SUBI.tgz" fastboot rom file downloaded from the link I provided above. In your MiFlash tool window, click the Browse button and locate the extracted fastboot rom folder. Then select "clean all" button at the bottom of MiFlash window. The flash tool is now configured. Now click the Flash button.
Wait for few minutes for the flashing process to complete, once the process is complete and MiFlash tool window will show task finished. But do not disconnect the phone.
Step 7:
Reboot to Fastboot mode & execute Fastboot commands:
Now while the phone is still connected to your pc, reboot your phone to fastboot mode by pressing Volume down button and Power button simultaneously until you see the boot screen and release, the phone will now enter into fastboot mode.
Now double click and open the cmd.exe file from AnF folder you extracted earlier to open the command window. Then execute the below command.
fastboot oem device-info​
This command will show you the current bootloader status. The bootloader status shows "Device Unlocked: False", execute the below command in command widow, it will Unlock the bootloader.
fastboot oem unlock-go​
Your device might restart now, if restarts press Volume down button and Power button simultaneously to reboot phone to fastboot mode again to check your bootloader status again by executing the below command. It should show "Device Unlocked: True" in the command window. Which means the device's bootloader is unlocked.
fastboot oem device-info​
Now to flash TWRP recovery and Supersu for root permissions, jump to step 8, or if your aim is to unlock the bootloader only, you may restart your phone and skip all below steps.
Step 8:
Flash TWRP:
Now restart phone to fastboot mode by pressing Volume down button and Power button simultaneously until you see the fastboot screen.
Extract the "twrp-3.0.2-2-kenzo for Redmi Note 3 _SD.zip" file downloaded from the link I provided above to the AnF folder.
Then open the AnF folder, double click and open the cmd.exe file, paste the below command in the command window to flash twrp recovery.
fastboot flash recovery twrp-3.0.2-2-kenzo.img​
After flashing the recovery image reboot the phone to TWRP recovery by pressing Volume Up button and Power button simultaneously until you see the boot screen. It will boot the phone into TWRP recovery, on the front screen just swipe the slider to mount system as read only. That's it now to flash supersu proceed to step 9.
Step 9:
Flash SuperSu:
While the phone is in TWRP recovery connect the phone to Pc, it will be detected as mass storage device, just copy the "SR1-SuperSU-v2.78-SR1-20160915123031.zip" file downloaded from the link I provided above to your phone's mass storage device.
On the twrp menu click on Install option and locate the "SR1-SuperSU-v2.78-SR1-20160915123031.zip" to install via twrp, now swipe the slider to right to install supersu to have root access in your phone's OS and then wipe dalvik cache using the button below in twrp.
If twrp shows any read/write error while flashing supersu, on the twrp mainscreen choose mount option and click on system in the next menu, then go back to main screen and try again to install.
That's it, now supersu is installed, to check the root status follow to step 10.
Step 10:
Check root status:
After completing all the steps successfully, reboot the phone into the system normally and complete the initial setup without Sim card, the first boot may take a little more time to boot into OS, In case if the phone stuck in boot screen for very long(10+ mins), go to troubleshoot section at the bottom and start over the steps. Otherwise you are good to go.
Connect device to Pc after initial setup completes, now copy the "Root Checker.apk" file to your phone and install it, open the root checker app and click on verify root, you will be prompted by Supersu for root permission, allow it, your root access will be verified. Voila, you have successfully rooted, flashed twrp and installed supersu on your Redmi Note 3 with latest rom installed.
That's it. Now you are ready to rock.
KNOWN ISSUES:
No issues found so far, in case if you find any issues after successfully unlocking using the above method, kindly let me know.
After successfully unlocking your bootloader, incase if you update your rom via official updates, your will lose root access and twrp custom recovery and may end up with locked bootloader again, if you face this situation by some reason, you may start over and follow this guide from step 1 to revert back to unlocked bootloader. Do not update the rom and turn off automatic updates in settings as a precautionary measure.
Troubleshoot:
If your device gets bricked or Stuck in Boot logo, try this,
Reboot your phone into edl mode by following below step.
If you are stuck on bootscreen, you may not be able to enter into edl mode using the normal method above because of bootloop or Stuck in Boot logo, in that case try this method to enter into edl mode from fastboot, download "fastboot_edl.zip" file from the link I provided above, extract the zip file and open the extracted folder, connect the phone to your Pc in fastboot mode(vol down + power), double click and run this file "edl.cmd", the phone will automatically enter into edl mode if the phone's drivers and adb drivers are installed properly.​Now follow step 6 and follow on from this step.​
If QHUSB_BULK drivers are not properly installed while the phone in edl mode,
If QHUSB_BULK drivers are not installed while the phone in edl mode, your device may not be visible in MiFlash tool(ex:COM10) even after you click refresh button, in this case open the device manager in your Pc, the phone will be visible as QHUSB_BULK with some alert sign, right click on it and select Update driver software. Then click browse my computer and browse to the location of the driver files in path "C:\Program Files\Xiaomi\MiPhone\Qualcomm\Driver" and proceed and when prompted to Install this Driver Software anyway, allow it and complete the driver installation. Now open MiFash tool and click refresh button your device will be detected in MiFash tool, now you can flash the fastboot rom by following the steps above.​
Does this work for Kate version also? OP doesn't specify
Will I lose my warranty by using this method of bootloader unlock?
This method still works for Global Snapdragon phone. Finally got it last night after 2 days of torture (I didn't sleep).
The important part is firstly the image with the modified file you are going to flash to the phone. Here he is using v8.0.6.0 which is the newest (and now last) update for android 5.1 (which is needed, phone will not flash 6.0 without a proper Cache and data clear). I ended up using version 7.3.2.0 which is 1 patch before the version my phone came with (7.3.7.0). Then I replaced emmc_appsboot.mbn with the one from here then flashed the file in EDL mode.
After the flash is done is just as important I found. You place it in fastboot mode (power button + vol down) and run a script. I wasn't able to manually unlock the device via cmd line 'fastboot oem unlock-go'. Instead I found a script that worked from here called 'Root_Folder' (this site also has majority of the files needed). You use the script called 'Root' in the folder to finish the unlock. Notice there is a 'recovery.img' in the folder as well, I replaced it with ZCX TWRP.
Now run through the script after the flash in fastboot mode. Follow the instructions from script, sometimes you take cable out or force phone back into fastboot mode. The key goal here is to have the script boot into TWRP in the end. If this happens you can do all that's needed now.
Another thing I noticed was you have to give debug permission to computer your using and save permission. Debug mode/oem unlock - connect cable, on phone you should get a prompt to accept PC and save permission. If you don't get this prompt make sure you have ADB and Fastboot installed.
Important steps are:
1. Phone connect to computer via debug/oem mode.
2. Flash correct modified ROM with MiFlash in EDL mode.
3. Once flash is done hold power and volume down button for fastboot mode.
4. Run script to attempt to unlock bootloader and/or install TWRP.

You would have to look it up for Kate specifically. If anything at all that changes it's the Image you use to flash the phone.

Don't think so. You don't 'officially unlock it' and you can flash a stock image that relocks the phone automatically.
Thank you works 100% !!!! :laugh:
After booting to TWRP it's asking me for a decrypt password and I cannot mount any partitions. Then I tried rebooting but phone is stuck on MI logo.

Can you boot back into TWRP? If not you'll have to reinstall from EDL mode and try to unlock bootloader again.
A decrypt password to access any of the internal storage? Did you have a password with last install of MIUI? Also boot into fastboot and see if your bootloader is unlocked with 'fastboot oem device-info'. If your bootloader is unlocked, you might have to reformat data files on phone, which will wipe system completely and remove encryption.
Oh you probably also need to put a SD card into the device to use to flash from, if your flashing a new ROM. You have to wipe main system with advance wipe, wipe everything but internal storage and micro sdcard (in TWRP).

Yes Praw Zoll, you can use this method for your device, I have tested this method working on Redmi Note 3 pro or Kenzo or Snapdragon variant.
You can also refer this miui thread for this same method with images and video, en.miui(dot)com/thread-461694-1-1.html

This method is for Redmi Note 3 pro, (Kenzo) variant.
can i use it for global stable 8.2.3 ??
The heart of this - the unofficial bootloader unlock - are taken from: http://en.miui.com/thread-345728-1-1.html (It's generally polite to link your sources).
This _does_ work on `kate`. However, this is using a modified 'emmc_appsboot.mbn'. If you flash an original emmc_appsboot.mbn, you may well find your bootloader no longer unlocked and you needing to reflash your device back to stock.
Also, for those wanting to use it on kate (because Xiaomi seems singularly incompetent when it comes to supporting the official bootloader unlock for that devcie): your device will identify itself as a kenzo, so you may have trouble flashing things like the 'miuifirmware_x.zip' updates for kate. Also, those 'miuifirmware_x.zip' files often include the emmc_appsboot.mbn, so be careful.
On another note, if anyone has an actual infallible method to get an official bootloader unlock for the kate device, please let me know.
Can I use this method for 2GB / 16 GB version of Redmi Note 3 Pro (Snapdragon)?
Thanks
Works Thanks
Tested On 18/05/17
This method works But You are stuck on a older rom with no OTA/Later Updates. Method Does not work with MM Roms.(Maybe with different emmc_appsboot.mbn it would work.
Some Pointers
I was on MIUI8 before using this.
1. This downgrades your ROM from the latest ROM, therefore Points to follow.
2. Use This Method Instead Works with latest firmware as on date.
Works, Simply Nicely Perfectly Done, Just follow the steps things will never goes wrong. :highfive:

You have flashed a recovery rom and that's why you are in bootloop.
Try to flash in EDL mode a fastboot rom.
PS: Hope you haven't tried to downgrade already because you can loose IMEI and baseband.

[HOWTO] Install Mokee 7.1.1 Unofficial cutom ROM for your new Zuk Z2 PRO for dummies

Hi,
Today I just installed a custom ROM for my Zuk Z2 PRO. This tutorial is how I did it.
I get many ressources from this forum and I thank orignal authors.
Big thanks to meister for his guide : https://forum.xda-developers.com/zuk-z2-pro/how-to/zuk-z2-pro-guide-to-everything-ota-t3562099
And big thanks to m_atze for his guide : https://forum.xda-developers.com/zuk-z2-pro/how-to/howto-flash-stock-rom-t3435109
More info on this ROM : https://forum.xda-developers.com/zuk-z2-pro/development/rom-share-lr-team-zuk-z2row-z2-pro-t3567710
Backup your data before processing the flash, in order to avoid loss of data!
Flashing / rooting and install custom ROM could brick your device ! You're the only responsible on what you're doing. This guide is how I did it and I'm not responsible if you're messing up your device
Unlock bootloader (step 3) will void Lenovo warranty
Antutu Score : 143050
Summary :
Step 1 : Prepare environment
Step 2 : Install ZUI 2.5.x (recommended before installing Nougat custom ROM)
Step 3 : Unlock bootloader (to be able to boot on TWRP)
Step 4 : Boot on TWRP to root the phone
Step 5 : Make a Nandroid backup
Step 6 : Install TWRP
Step 7 : Install a custom ROM with TWRP
Step 8 : Install Gapps (google apps)
Step 1 : Prepare environment
Create a directory where you're gona extract download files (avoid space in the directory path).
Download : adb and fastboot from google
Extract it on your previous created directory.
Download usb drivers and install it
Enable developer mode in your Z2 PRO (link if your don't know how to do it)
Connect your phone on your computer
On the directory C:/yourDirectoryPath/platform-tools maintains shift + rigth click and "Open command window here"
Type adb devices
If your see a line below "List of devices attached" your adb is OK
Note the number somewhere, it's your device serial number.
On the phone type *#06# and note somewhere IMEI numbers in case something went wrong during flashing
Step 2 : Install ZUI 2.5.x (recommended before installing Nougat custom ROM)
For this part I use the m_atze tutorial that you can find here. Check it for me detailed steps.
If you are on windows 8, 8.1 or 10, you have to disable driver verification (some people didn't disable driver verification and it works as well)
For windows 10 with anniversary update : you just have to run a cmd as admin and enter bcdedit -set TESTSIGNING ON then reboot your computer (your windows will be in test mode)
For other cases check this link
Then
Download QPST flashtool
Install QPST flashtool and reboot your computer
Download and extract ZUI ROM 2.5.x (you maybe need to rename the directory where the ROM is because it could be too big)
Launch QFIL application as administrator
Go to Configuration -> FireHostConfiguration. 1-change device type to UFS. 2-check reset after download checkbox
Click on "Load content" and browse the contents.xml from the ZUI ROM 2.5.x extracted files
On the adb console you opened earlier, enter adb reboot edl
The QFIL page should look like this
Click on "Download content" to flash your phone
The final screen should like this
If any problem, there is an FAQ
Your phone is gonna reboot, congratulation, you're flashed your phone with ZUI 2.5.x ROM.
Once the phone boots up it will be in Chinese again. To get your phone back in English :
On the welcome screen tap the bottom of the screen below the highlighted blue text to skip the ZUK login.
To change the language back to English go to Settings.
In the third section choose the last entry. "Advanced Settings" (the gears symbol).
Choose the 2nd menu item.
Choose the first menu item and select English.
Now check update and install it if needed trough this app. If the check is green, it's ok.
Re-enable developer mode and debugging
Step 3 : Unlock bootloader (to be able to boot on TWRP)
This step is almost a copy past of section 2 of meister guide
This step gonna void your Lenovo warranty and wipe your data
Step 3.1 : Get the unlock bootloader from Lenovo
In order to unlock the bootloader you will need to got the zuk website, where you need to register first before you can request to unlock the bootloader.
So go here : https://passport.zuk.com/wauthen3/wauth/jsp/register.jsp (use google translate)
Select Email Registration (upper right corner) and fill in the required data
You will receive an Email with a confirmation link.
Now that you are registered, log in and than go to http://developer.zuk.com/bootloader (use google translate)
Click on Carry On.
On the next page select your phone type Z2 Pro.
Enter your serial number (8 digits) (you can find it on Settings -> About -> Status. If your serial is not 8 digit, add 0 to the end to make a 8 digit number)
Enter an email address where to send the unlock image. It seems that the email address here has to follow some rules. ([email protected] or @Web.net seems to work. A domain name with a hyphen (-) seems to cause problems, i use a @hotmail.com mail adresse and it worked)
Check the 2 check boxes and click SUBMIT
If successful you get a message that the image has been sent to your email address. No message means something went wrong. Likely the email address was not approved.
Save the email attachment from ZUK you requested earlier (named unlock_bootloader.img) into C:/yourDirectoryPath/platform-tools/ (next to adb.exe)
Step 3.2 : Unlock bootloader
On adb console enter adb devices to check if your device is still connected
Next enter adb reboot bootloader and your phone gonna reboot in bootloader mode
Next enterfastboot -i 0x2b4c flash unlock unlock_bootloader.img (if you got error "target did not report max-download-size" change from usb 3.0 to usb 2.0 port and / or try to turn on "enable_usb_2.0" via
Developer Options)
You should see
Code:
target reported max download size of 1610612736 bytes
sending 'unlock' (0 KB)...
OKAY [ 0.031s]
writing 'unlock'...
OKAY [ 0.063s]
finished. total time: 0.094s
Then enter fastboot -i 0x2b4c oem unlock-go
You should see
Code:
...
OKAY [ 0.031s]
finished. total time: 0.031s
You phone is gonna reboot (or reboot it manually)
Change the phone language to english and re enable debugging.
Step 4 : Boot on TWRP to root the phone
Download TWRP 3.1 for Zuk Z2 PRO here and extrat TWRP..... .img next to adb.exe in platform-tools folder
Download SuperSu here
Copy paste SuperSu zip file in your phone internal storage
In adb cmd enter adb reboot bootloader
Then enter fastboot -i 0x2b4c boot TWRP3.1.0.0_ZUK_Z2_pro.img to boot in TWRP image
Click on "Keep read only"
Go to install and browse to SuperSu zip.
Swipe to install
When installation is finished, reboot your phone (it may reboot many times)
Good job, your phone is now rooted !
Step 5 : Make a Nandroid backup
In adb cmd enter adb reboot bootloader
Then enter fastboot -i 0x2b4c boot TWRP3.1.0.0_ZUK_Z2_pro.img to boot in TWRP image
Go in backup and check all checkbox
Swipe to backup
Reboot the phone
From your computer browse your phone internal memory and copy your backup from TWRP/Backup/XXXXX to a directory in your computer
Step 6 : Install TWRP
In adb cmd enter adb reboot bootloader
Then fastboot flash recovery TWRP3.1.0.0_ZUK_Z2_pro.img to install TWRP on your phone
Then fastboot reboot
Then adb reboot bootloader
Then with volume keys select Recovery Mode and enter in Recovery Mode by pushing power key
TWRP will start
Reboot your phone
Step 7 : Install a custom ROM with TWRP
Download ROM from https://uploadfiles.io/55ffa
Copy paste ROM zip file in your phone internal storage
In adb cmd enter adb reboot bootloader
Then with volume keys select Recovery Mode and enter in Recovery Mode by pushing power key
Click Wipe and swipe to wipe. Do NOT reboot your phone.
Go back in TWRP main menu and click Install. Browse the ROM zip file
Swipe to install
Reboot your phone
When your phone reboot, it's in chinese. Click on the texte in the right bottom corner and then select your language.
During the phone configuration, do not connect wifi (in my case the phone configuration crashed when I connected to a wifi)
When you finished phone configuration reboot to get notification in your language
Step 8 : Install Gapps (google apps)
Download Gapps from https://forum.xda-developers.com/android/software/gapps-dynamic-gapps-t3487192
Copy the zip file in your phone
Reboot in TWRP
Install Gapps through TWRP
Reboot your phone
At this point my Google Play Services crashed each reboot. So needed to
Reboot in TWRP
Wipe cache
Now it works !
You can install other ROM with this method but I only tested with this one.
Enjoy
First of all, thank you for your help.
I followed this tutorial from start to finish without encountering any unexpected events. It is rare to say so!
Small points:
Step 1:
*- Think of connecting the phone before the command "adb devices", it's stupid but I had not done it!
Step 2:
*- I did not need to change my driver settings on Windows 10.
*- I had to run the QFIL application as an administrator.
*- I had to rename the directory where the ROM was because the name was too big.
Step 3.1:
*- I have a serial number on 7 characters, you must add "0" at the end to make 8 characters.
*- My Gmail address worked smoothly.
Step 4:
*- The SuperSU link did not work, I took this one: http://downloadmirror.co/Utz/UPDATE-SuperSU-v2.79-20161211114519.zip
*- Some reboot at home also, it seems to be normal.
Step 7:
*- I took the ROM "Resurrection Remix", no problem with another ROM.
Step 8:
*- I also had a crash of Google apps, I also did a wipe and it works now. It looks normal too.
Thank you again for your help!
Glade I could help !
Thanks for your feedback, I'm gonna update the tutorial
Hi,
great tutorial, thank you!
Step 6 : Install TWRP - I'm stuck though, as my PC still does not recognize device on fastboot without -i 0x2b4c...
so should I use instead of
Then fastboot flash recovery TWRP3.1.0.0_ZUK_Z2_pro.img to install TWRP on your phone
Then fastboot reboot
Click to expand...
Click to collapse
the -i option ?
Then fastboot -i 0x2b4c flash recovery TWRP3.1.0.0_ZUK_Z2_pro.img to install TWRP on your phone
Then fastboot -i 0x2b4c reboot

Mk60.1 have exactly the same bugs like Mk71.1. so no need to use mk60.1. mk71.1 is pretty stable btw.

I prefer this ROM because you can custom it in many ways.
Since yesterday it's stable.

1. Method 1 require unlocked bootloader. If you want to unlock then go Here . Method 2 doesn't. Don't worry.
2. This will clean your phone just like new phone.
3. First read the post twice carefully then proceed.
4. ALL .bat FILES TO BE RUN IN FASTBOOT MODE ONLY, IF YOU DON'T KNOW ABOUT FASTBOOT MODE THEN GOOGLE "HOW TO GET FASTBOOT MODE IN ASUS ZENFONE 2
5. I may change name of files in folder. Use common sense to identify them.
Pre-requisites:
1. Charge your phone atleast 60%.
2. Backup any important data you might not wanna loose to either sd card or usb drive or pc.
3. Copy the rom zip in the sd card of your phone. (The one with size in GB)
4. Android USB Driver should be installed already, if it is not then install all drivers in the "Drivers Folder".
5. Enable USB Debugging.
For that go to "Settings" ,Scroll to bottom goto "about", goto "Software Information", tap "Build number" upto 7 times or till it
says "You are a developer now". Then go to "Settings" you will find "Developer Options", open it and enable "USB Debugging"
4. Common sense, patience.

Code:
fastboot erase cache
Step 6: You should see stock recovery options. Then choose "Update from sd card" and select the rom zip you pasted in SD card.
(If you don't have sd card, then paste rom in internal memory and don't tick "internal storage" in twrp in step 2) But micro
sd is preferable.
Step 7: Wait. Your phone may take 20-30 or more minutes. So leave it on charging.
METHOD 2​Step 1: Download and Install all drivers given in download folder. Download RAW firmware for your phone. See above in download links.

Sol. Make sure you have enabled USB Debugging (Not applicable for BL Unlocking and TWRP Flashing)
Uninstall all drivers previously installed on computer(every driver of any device)

Would it not be easier to get the stock raw image and just flash it with the asus flash tool?

Thanks for suggestion. But the reasons​ are
First thing is stock raw image of latest version is very difficult to find.
Second thing sometime asus flash tool stops responding. So you have to wait again for 30 minutes. Also it doesn't show progress sometimes.

No offense meant. But the entire collection of raw files are here: https://forum.xda-developers.com/showthread.php?t=3448966
As long as you have the correct drivers (which you need for your process too) the AFT will get the job done in one easy step.

Man, this thread saved my ass. thank you for all your time all!
I have the Asus Zenfone 2 ZE551ML with sound issues, (it's only when the phone rings that the speaker works) and I put it into recovery mode to wipe cache/data, but it got stuck while doing that and I forced it off. But now, it's stuck at the Asus Boot logo with the rotating icon underneath.
Please help!!!!
Hello, my 551ml has stock LP, it's rooted with bootloader unlocked and Xposed installed. If I want to install the latest MM with through the raw flashing tool, should I install the MM bootloader first or it is included into the raw file? Thank

Ok. humm, in AFT, it recognize my phone. (there is no OS on it), i choose the good model, i choose the good firmware, but i got this error in a box
"Can't open file 'SERIALNUMBER_frp_request_server_log.txt' (error 5:denied access)" i can only press OK
and now the button under "state" is red and under description, it's " check the detected serial number failure (not found the device of "SERIALNUMBER") "
you understand the i've replace the real serial number by SERIALNUMBER in those lines.
Anyone ever had this problem?

did you find any?
i want to remove the lineageos and install latest stock LP but i have no clue how to do it

[ROM][ROOT] 825x Pro 4GB RAM and 64GB storage

Only for headunits based on MTK8257/MTK8259 chipset like the Junsun V1 Pro
This is based on the newest update "8259P_军灿UI02v1280x720-国外_v27_20211201"
Full stock rom with Magisk patched boot image and Magisk manager installed. It will display an SU error in Magisk manager but just ignore it since it still works.
Just flash with SP Flash Tool. Remember to format before flash
Download: 825x Pro ROOT
I have no responsibility if you brick your device, do it on your own risk!
HOW TO FLASH:
1. Open flashtool
2. Select the scatter file provided in the ROM (AC8257_Android_scatter.txt) in the Download tab. All the different partitions should now be selected.
3. Click on Format tab and then make sure "Auto Format Flash" and "Format whole flash" is checked.
4. Press Start on Format and boot your device into preloader mode, there are several guides for this. My device boots into preloader mode for a brief moment if you just cut the power and apply power again. It will stay in preloader mode if you have started the SP Flash Tool Format or Flash until it is finished.
5. When the Format is done you will see a green OK window.
6. Then go to the Download tab and make sure it is "Download Only" and then press Download and then reboot your device into preloader mode.
7. It will take a long time until it is all finished. You will see the same green OK window when it is done.
Also, noticed that the clock and stuff wont work correctly if you dont make a Factory Reset after it has booted up for the first time. The problem is though that Magisk Manager will be uninstalled. But if you just download Magisk Manager again it will work fine since the BOOT partition is already patched.
Please tell us the sequence of actions when flashing via the SP Flash Tool ?

Thank you very much!
There are a couple more questions:
1. Where do I need to write all the contents of the downloaded directory: "825x Pro ROOT" ?
2. Which version of Magisk Manager is installed ?
3. When formatting flash , will the IMEI ID fly off ?

No worries!
1. I dont really understand your question? But i guess you are talking about the files in the folder. When you open the scatter file all these files should be selected for each partition. No need to change anything.
[EDIT] or on the other hand maybe you are asking about the zip file. You need to unzip it first!
2. The latest from Stable channel
3. I have not noticed anything related to the IMEI. I have a IMEI number on my device still after the flash, though i am not really sure if it is unique to my device or if it will be the same for all devices that flash this ROM.
