1) How to install? If you have stock zenui go to 1C, if you have a custom ROM go to 1A
If you don't backup all your data you lost all.
1A) First do a TWRP backup on sdcard (if you don't have sdcard just do in internal storage and save the backup on pc. Select system, data, recovery and boot. Then go to wipe - advanced wipe, select dalvik, system, data, cache and Swype.
Then reboot in fastboot.
Now your phone don't have any OS installed so don't boot. We are going to install the stock and unmodified firmware and recovery on the phone.
1B) Download Asus flashtool:
https://drive.google.com/file/d/0B9rp3AJHKJXjNmRuRUJMWmtOT3c/view
and android 7 raw firmware for
ZE552KL:
http://www.mediafire.com/file/o12vo...14.2020.1703.28_M3.10.47.3_Phone-user.raw.zip
ZE520KL: http://www.mediafire.com/file/5qrp2...14.2020.1703.28_M3.10.47.3_Phone-user.raw.zip
Now boot your phone in fastboot, connect to pc, install and open Asus flash tool, select raw file and device model and flash the firmware. If the pc don't detect your phone install the drivers.
1C) Download from Asus site the latest nougat update:
WARNING: IF YOU OPEN THE ZIP FILE THE RECOVERY FAIL TO UPDATE
And you must delete this zip and download another
ZE552KL: http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE552KL/UL-ASUS_Z012D-WW-14.2020.1712.85-user.zip
ZE520KL:
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE520KL/UL-ASUS_Z017D_1-WW-14.2020.1712.85-user.zip
Put in device storage and wait the device to detect the update. Tap on notification and install. If fail try in order:
-put in sdcard and update via STOCK recovery
-‎sideload the file from your PC via adb
-‎download the file with another browser and delete the previous
After that, so the same with Android 8.0 update
ZE552KL: http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE552KL/UL-ASUS_Z012D-WW-15.0410.1712.31-user.zip
ZE520KL: http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE520KL/UL-ASUS_Z017D_1-WW-15.0410.1712.31-user.zip
2) Flash recovery
I know there are another method to flash a recovery but this method is simply:
2A) Download twrp from this thread:
https://forum.xda-developers.com/zenfone-3/development/recovery-twrp-3-2-1-ze520kl-ze552kl-t3742765
Download Zenfone 3 toolkit from this thread:
https://forum.xda-developers.com/zenfone-3/how-to/tool-zenfone-3-one-click-tool-t3507417
2B) Unpack and go to zenfone3_clictool/twrp folder. Delete both recoveries and put the 3.2.1 twrp in folder. If you have ZE552KL rename with " twrp-3.0.2-Z012D ", if you have ZE520KL rename with " twrp-3.0.2-Z017D ". Now boot your phone in fastboot, connect to pc and open the Zenfone 3 click tool, follow the instructions and select flash twrp for your device. Reboot your phone in recovery and see if can read internal storage. If read 0B try another time.
3) Rooting is so simple. Just download Magisk
boot in twrp and flash
Xposed work well, I tested only gravitybox
Substratum works... Meh

Great job!
However, I have a question. TWRP you mention to in 2A's version is 3.0.2 or 3.2.1?
I'm sorry that my English is bad.

So, just to be sure, I'm currently on ViperOS, I need to follow from 1A step, right? Or anything before that I have to do first?

Is 3.2.1 . It's a beta TWRP so may have some bug. But basic functions works

No, it doesn't work on the ZE520KL.
As oreo is finally available on this phone I'll also build a new twrp version for it
(If anyone is wondering: I posted OP's twrp some time ago in the oreo beta leak thread here)
Stay tuned...

The ZE552KL TWRP works fine for flashing the Magisk at my ZE520KL but not much else
I can't wait to get a proper TWRP for my ZE520KL

Will this also work for Z012DC (Canadian 5.5" Zenfone3)? I'm running WW_14.2020.1709.68 with TWRP and rooted, would I start from 1A or 1C?

Ok, so I flash TWRP recovery and everything is OK, but, When I start the phone, it goes to bootloop...What should I do? Am I missing a step?

@Kevinxdfun29
Flash magisk, supersu binary or the no verify file if you don't want root. Then wipe cache and dalvik .

My phone is now WW-15.0410.1712.31
I cant sure that my phone will boot or not after flashed twrp. So I go to fastboot mode, and boot into twrp by command:
fastboot boot twrp-3.2.1-0-Z012-20171220-oreotest.img
downloading 'boot.img'...
OKAY [ 0.786s]
booting...
But nothing happens, my phone still in fastboot mode.
I can boot into twrp with beta oreo previously released.
I think that twrp is not compatible with official oreo now.

Try install recovery following the instructions in first post. Worked for me
If the "zenfone3 clicktool" method not work try
fastboot flash recovery twrp-3.2.1-0-Z012-20171220-oreotest.img
So reboot in recovery and give me a feedback

Yes. I flashed the twrp successfully. But I cant boot into twrp without flashed it. I need to backup the latest stock recovery, in order to flash a new stock rom in future.

Wrong thread bro

In need of help! TWRP!

first some back story:
it's been a long time since i did a lot of rooting so i lost a lot of knowledge.
I got the phone close to release in the EU.
There was only BETA stage twrp at the time.
So i flashed this unstable twrp and rooted with magisk.
And i run stock Oxy Rom.
But the main problem is, whenever i boot into recovery, twrp ask me for a password. (i have none) so i press continue.
And it then ask for unmodified system partition. (not sure what to select here)
But when i swipe to allow modification, i can't find the root of the phone? i cannot find the download folder where i flash updates or other modified apk's.
It's all just numbers and random letter. i have no idea on how to proceed or how to update twrp safely without falling into boot loop and other problems.
Some help would be appriciated. Thank you.

and which of my problems does this solve?

First of all flash official TWRP now. Makes no sense to use the unofficial version because its not stable.
Enter PW -> decrypt data for TWRP
No PW -> hieroglyphs

I successfully used official twrp, version 3.2.2 and then did a "format data" and then used fastboot again to install the full rom.

U have corrupted u r data partation u have to factory reset along with wiping internal storage and then transfer u r rom File through MTP in sd card of phone and then flash rom.
Or u can flash fastboot flashable rom via fastboot mode.
Then install your official twrp via fastboot mide after installing rom.
Now twrp will detect all data from sd card

Can Anyone help me, please? I have somehow the same problem. The phone literally itself without doing anything started doing a download(odin) mode loop. So I deleted data, dalvik, cache, system partitions without internal storage since it has very very important files for me and a lot of projects for the university!!! and before and after the folders in internal storage in twrp shows as random numbers and letters. I don't know why since when the phone was working normally I was protecting it by fingerprint and a password. And when I installed a stock ROM after it without wiping the internal storage. The storage is showing in negative. If anyone can help me this would be super appreciated and helpful. Thank you!

If it is already showing folders with random file names in the internal storage it means it needs to format data (to remove file encryption) which deletes all files in the internal storage.
Don't wipe system because it removes your OS.
Always secure backup before messing your device.

You may try this boot.img just rename to boot.img only.

Sorry I thought you are also literally same issues with OP but then it's not. Are you able to reboot to twrp? And what is the whole story of you device? I mean if you are rooted, what ROM you came from and all that you did before the issues occur. And did you tried to switch slot? Since you wiped everything with system included then you have no OS installed. Did you tried to flash OS via OTG? Or flash via fastboot.

I flashed another os without deleting the internal storage but the storage is now showing in negative values. Story is The phone literally itself without doing anything started doing a download(odin) mode loop. So I deleted data, dalvik, cache, system partitions without internal storage since it has very very important files for me and a lot of projects for the university!!! and before and after the folders in internal storage in twrp shows as random numbers and letters. I don't know why since when the phone was working normally I was protecting it by fingerprint and a password. And when I installed a stock ROM after it without wiping the internal storage.

Teclast M89 problem installing TWRP

Hi folks. As the title suggest I'm having problems installing TWRP recovery on teclast M89 tablet. I've tried a few different tutorials with no success. When I do it with fastboot it says that its installed, after that when I try to reboot the device, I'm stuck in bootloop. I've tried to do it a few times and its always the same problem. Does anyone have a solution? Thanks.

Hello, the same for me with my M89, I'm going crazy.... Help us please!!!! Thanks!!!

Teclast M89 TWRP 3.3.1
Teclast M89 TWRP 3.3.1
TWRP 3.3.1 for Teclast M89
The archive includes:
ZIP file for flashing via stock recovery
IMG file for flashing via fastboot
TWRP source code
Teclast M89 uses well-known firmware signature Android keys (test keys), that's why you can flash TWRP without unlocking the bootloader and erasing user data.
Installation instruction is inside the archive.

This TWRP worked like a charm for me. I had already rooted via Magisk- but was really looking for a working TWRP for backing up before I really went crazy with mods.
Thanks so much!!

Hi, i tried this method but couldnt boot in system, only twrp all the time. after initial install this TWRP 3.3.1, it bootlooped in twrp but storage wasnt seen in pc, so i formatted data and restarted in twrp. from there it couldnt restart system anymore. actually i managed to flash magisk 19.3 . i flased another version of twrp 3.2.3 that seemed to work fine, to see if it was the version, and it bootloops (restarts until logo) all the time. Any hint please?
It says in little print "your device now unlocked...your device will boot in 5 seconds" but restart. Cant get it into fastboot by volume up; unresponsive at all. just bootloops in logo.
Any help is very much appreciated. thanks

Hi
I think you are going to have to reflash the original Rom using SPFlahtool. Then you must install Magisk Manage on tabletr. Copy the boot image from the ROM files to Your phone. Then use Magisk Manager to Patch the copied boot image. Transfer modified boot image to PC. Use fastboot to flash modified boot image back onto the tablet. The long and the short of it is - you need to find a way to patch the boot image with Magisk before any TWRP will work.

Right. The problem was accesing the tablet enough time as it stayed connected and recognized by pc only 3-5 secs, and then permanent unresponsive through buttons, but i used then sp flash to just flash boot, then preloader, then recovery from stock at every reboot. From there i could turn it off, It got out of the loop, and accesible to reflash whole stock rom. In the end i only flashed magisk through fastboot, as twrp is not so useful to me as no custom rom, so better no risks.
Thanks for your reply though

I am glad you got your tablet running again. I had originally started out with just Magisk as root also. I do like to have a working TWRP for backing up though. You should be able now to flash the above mentioned TWRP now via SpFlashtool or fastboot.

Hi, i tried this method but couldnt boot in system, only twrp all the time. after initial install this TWRP 3.3.1, it bootlooped in twrp but storage wasnt seen in pc, so i formatted data and restarted in twrp. from there it couldnt restart system anymore. actually i managed to flash magisk 19.3 . i flased another version of twrp 3.2.3 that seemed to work fine, to see if it was the version, and it bootloops (restarts until logo) all the time. Any hint please?
It says in little print "your device now unlocked...your device will boot in 5 seconds" but restart. Cant get it into fastboot by volume up; unresponsive at all. just bootloops in logo.
Any help is very much appreciated. thanks

It seems OEM unlock fills "para" partition with some data which forces it to boot into recovery. Stock recovery reads this data and perform data partition wipe or something similar, but TWRP does not handle this data and you get a boot loop. You can fix that by cleaning "para" partition. Execute the following command while booted into TWRP, either from TWRP terminal itself or from adb shell:
Code:
dd if=/dev/zero of=/dev/block/platform/mtk-msdc.0/11230000.MSDC0/by-name/para

No. It won't. I bricked my ****ing tablet. It refuses to reboot once it's unlocked because (as the screen say) it is now untrusted. There is no way to relock the bootloader again and the the tablet is stuck in a bootloop.
Teclast is ****.

Hello i'm new in XDA, i have this tablet althougth i can't conect the hdmi port to the tv, the screen keep in black, i think it's because of the display format (4:3) can the root solve this problem?
Thank You!!

The bootloop is not because you've unlocked the bootloader, but most probably because the firmware is designed to perform userdata partition setup in the recovery upon first boot, and you don't have stock recovery, that's why it can't finish formatting procedure.
This could be fixed by flashing stock recovery and booting once.
You can ask for a firmware from Teclast (I used to ask them on vkontakte because they didn't respond my mails), they will provide it.
OR you can write zeros to "para" partition using fastboot, it should do the trick too.

Try to unplug/plug again HDMI cable several times. It seems that the HDMI controller or drivers are buggy.
To change the resolution I use "SecondScreen" software (requires root).

Hi guys,
I´m looking for a working rooting method for my Teclast M89 Pro model ??
Any idea ?? What about the "One Click Root" Program ???

Are you trying to enter recovery right after flashing it, without booting the OS first? I think you need do enter TWRP right after flashing it.

GUIDE | Go Back to Stock ROM | Recovery | Fastboot

Prerequisite
1. Unlocked Bootloader
2. OrangeFox Recovery or TWRP Recovery
3. Latest adb & fastboot files
4. Stock ROM ZIP files
5. Stock Recovery [OPTIONAL]
Custom Recovery Method:
1. Enable USB-Debugging: adb reboot recovery or hold the volume up while rebooting or hold the volume down to enter bootloader & choose Reboot to Recovery by volume buttons, power key to enter.
2. Copy the Stock ROM zip to your device via adb push RMX1851_flashable_*.zip /sdcard or MTP
3. Wipe data, cache & dalvik (format data if stuck at boot animation)
4. Locate the zip file & Install
5. Flashing all the partitions with stock files takes time. Hold for a while.
6. After successful install of the zip. Your device will have Stock Recovery with Stock ROM. Finally Reboot.
Fastboot Method:
Note: Following process formats internal storage, so backup the internal storage files. If your device is in Stock ROM & somehow system partition is messed up just flash only system.
1. Download required Fastboot files
2. If downloaded 7z files, extract system.img file.
3. Enter
Code:
fastboot -w && fastboot erase system && fastboot flash recovery recovery.img && fastboot flash boot boot.img && fastboot flash vbmeta vbmeta.img && fastboot flash dtbo dtbo.img && fastboot flash system system.img && fastboot reboot
4. It takes a while to flash System partition, have patience.
5. Device reboots to system if everything is flashed successfully.
Stock Recovery Method:
1. Download Stock ROM OZIP Files & Stock Recovery
2. Copy *.ozip to sdcard or internal storage.
2. Goto fastboot & enter fastboot flash recovery recovery.img
3. Reboot to recovery, wipe (1st option). Then go back to main menu Install from storage locate the *.ozip file & install.

I followed this guide, everything went smooth, magisk was also installed and rooted. But I tried setting fingerprint and set lock pin, But it says wrong pin everytime, so i had to reset the phone again. I used the same method above. But this time magisk won't install no matter how many times I reset my phone using the above method. So I thought if I could revert back to stock, maybe I can root and install magisk again. So i followed your guide.
After installing the stock zip and reboot to system, it stuck on bootloop(realme logo), then I flash back using the above method again, I can log in to the phone, and red notification says root has been detected, but magisk is not installed, ive tried many things but still i cannot install magisk. I've tried your guide 2/3 bootloop everytime. What could be the problem? I am not very much of a tech genus :'(

ok no problem, so what do you want to know about? Clear data, cache, dalvik after or before flashing stock zip it won't bootloop. Yes, since device is decrypted lock screen doesn't work.

no that's not how magisk works in Realme 3 Pro, if device is restarted there will be no magisk. You need to goto fastboot then goto recovery, it boots to system. We have magisk. Yes this method tricky. I am going to publish new guide, it will be simple & straight forward.

I have seen you have started a new thread of bootloop. Is this because you flashed one of these stock zip? you were going back to stock from los?

this method worked perfectly fine for me. i tried both lineage os roms available and both of them caused bootloop or end up destroying boot. so thanks to developer for making this zip file.

bootloop to recovery? have you tried fastboot -w usually this should boot to system or else flash stock recovery, wipe full. This should definitely get back the device to system.

Need Help
Hi, everybody. Really need help.
There is a phone Realme X Lite. Write that it is Realme 3 Pro for the Chinese market, as well as firmware.
My version was: RMX1851_11_A.05
Tried to flash RMX1851EX_11_OTA_0150_all_2Zfcensdoezk.ozip, recovery gave an error, *_0140_* wrote that the current version is newer.
In depth test APK on the version out of the box wrote that this version of the phone is not supported, so the bootloader could not unlock.
But in the official website came across an offer to join the testing of Android Q
r1.realme.net/general/20190522/1558492614147.pdf
There are two files, the second for rollback.
I installed P2Q, everything went well, but the SnapDragon camera is used and it is terrible if there is not enough light. In depth test is not even installed, apparently not supported in the new version.
I decided to roll back, chose in Recovery Q2P archive, there were no errors, but after rebooting the phone hangs on the initial screen saver and after 10 minutes throws in the recovery with the error "Data error, select wipe data to recovery system". Wipe doesn't help. The same with other archives for Realme 3 Pro.
Also found RMX1851_11_A.12_190423_abecd1fa.ofp for firmware via MsmDownloadTool, but it requires authorization and support refuses to call login details.
Can who faced a similar problem on this or other phone.
Please help, pay for the time spent =)

since your bootloader is locked, all you can do is wipe full data or flash back P2Q then format & then flash Q2P.

TF300TG after flash nougat 7.1 not boot

Goodmorning everyone
I have a problem on my TF300TG which I picked up from my drawer after a while
I upgraded to 7.1 nougat following the instructions given in the letter (very clear) but now my tablet does not start the system, I explain better:
it turns on and the writing unlock remains The device is unlocked with the ASUS logo in the Center but does not start.
I can go back to recover twrp at any time and reflect what I have repeated several times even with different versions but I always have the same problem.
I can also re-revise the original flash blob and start again

Yes, you should do carefully a Buster99: https://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
This procedure brings you back on a clean stock rom Android 4.2 Jelly Bean. Then you have to flash Kang TWRP firstly.
PS: Attention! If you restart in recovery with the 3 icons, never touch the third one in order to "Wipe Data". It bricks your device!

It seems there has been a big misunderstanding by you. I advised to format data through Kang TWRP, but you did a factory reset, didn't you?.
Too many people mix up wipes and formats. Format only data means, not factory reset, not wipe - you format it ext4, then convert it to f2fs. Formatting in Kang TWRP takes until 1 hour. If it went faster you did not format. Kang TWRP does a deep format that rewrites everything in the partition. No moldy leftovers.
Now your device is in a boot loop, but not bricked. So doing a Buster99 is the only way to solve the problem. If you need help with fastboot, head over to the General section. Download and install "Minimal ADB and Fastboot" on your PC.

I'm sorry, but it is not easy to understand what you did. As far as I know your device is on stock rom Android 4.2 Jelly Bean. Correct?
The next step should be to flash (not insert!) "twrp_tf300t_kang_2.8.7.2_signed.zip" via fastboot. The command is: "fastboot -i 0x0B05 flash recovery foo.img". Replace foo.img with the recovery image name! Did you?
If yes, you may start the device into recovery. Kang TWRP should start. After that install through TWRP Nougatella #39, pico Gapps and Super SU from the external memory of your device in one run. That's it!

KatKiss-7.1_TF300T_039.zip, open_gapps-arm-7.1-pico-20200325.zip, SuperSU-v2.82-201705271822.zip all OK
I ran Wipe cache / dalvik
I restarted
performed a first start where the bar under ASUS quickly colored blue
It has restarted
but later stuck on ASUS. I don't know where I'm wrong

From the fact that you have not replied to my last message, I think we have given up.
Just one thing I'm curious to know are there versions of this Tablet with different hardware or different firmware (bios) you can update? I don't know I thought even if I had to have a rom already cooked and functioning on an equal tablet I could shoot it in a single flash

I'm sorry, but I also don't know where have been wrong? How should I reply after so less information about the situation. There are many different possibilities.
Hopefully you have a backup of the system through TWRP after finishing the Buster99. If so, please start the TWRP recovery and restore the backup.

Sorry but once done the Buster99 procedure I don't need to do a restore of the Backup since the tablet restarts regularly with the original system I didn't perform any backup I didn't need it
