[GUIDE]How to Revert to Stock/Reflash firmware/Unroot[TWRP/NON-TWRP]

Hey Xda,
Today I present you a guide on how to
REVERT TO STOCK OR REFLASH​ firmware on the Asus Zenfone 2 Laser ZE5550KL.
This guide is applicable to both types of users ie who use TWRP and who don't use TWRP.After following this guide your phone will also be unrooted.
For TWRP Users
Here I give you links to two firmwares which you can directly flash via TWRP recovery.
Version:1.13.40.496
Link
Version:1.17.40.1234
Link
For Stock/Non-TWRP Users
The procedure is a little long here ==>
1. Download the official firmware from asus website.
2. Copy the firmware to the Micro-SD and rename the file (firmware) by one more(version).This renaming should be according to your current firmware version.If you have 17.something firmware and you download 16.something firmware then rename the 16.x.x file to some thing like 17.x.x For eg. if you have 1.17.40.763 then rename 16.x.x file to 1.17.40.764.
3. Reboot the phone.Android should automatically find the update file and offer to automatically update the software.Do it !!
4. Go to stock Recovery and wipe cache , dalvik cache and data.
5. Reboot device. Your phone will now be unrooted(if it was rooted before).
DONT FORGET TO PRESS THE THANKS BUTTON IF I HELPED YOU.

Before going back to stock and re-rooting to see if the issue was still present, I thought I'd ask if this is something to worry about ? I have the ZE551KL (Z00T) and have been flashing for this device with no problems whatsoever. What is it that I did while unlocking , rooting, and flashing twrp that may explain why the build number and device model don't match? Additionally, at times my PC will recognize my device as a MotoG when my device is connected to the PC via USB . I don't have access to my PC right now so I can't say this with certainty, but I think my PC recognises my device as a MotoG only when the device is in TWRP.. Maybe that means something was done wrong while unlocking the bootloader?

Lemme guess. You use that stupid custom kernel? That'd explain why About Phone says it's Z00LD.

Well, I'll be damned. I was doing so much flashing at the time that I didn't put it together. Oh well. I've been back on the stock CM kernel for days and everything finally works as it should again.

Will flashing this stock ROM on TWRP replace my current TWRP recovery to stock recovery on boot?

Thank you for being quick. I upgraded to Nougat and then tried to root and my phone stuck in recovery mode boot loop. I was able to downgrade to 6.0.1 with odin md5 file. This will help get back to Nougat and attempt to root again.

What version of odin did you use and where did you get these files from?

omg...thank you thank you thank you thank you!

If I'm on the U firmware can I update directly to this via Odin?

70 downloads and only 5 thanks seems a little unreasonable for the first Odin 7.0 files.

I have an att branded S7 Edge with 935u FW on 6.0.1. Flashing these files will update me to Nougat correct? Also what version of Odin should I use to flash? TIA!

Oh how I wish I had this when I softbricked my device last weekend, had to flash the tmo firmware over the non booting at&t firmware

flashed this a couple of days ago and so far everything is great.

when I unzzipped the files, I see 4 zip files ending with .tar, they just need to be placed in odin to flash, correct? Or do I need to rename them to .md5

No need to rename. When you open Odin you'll add the files to Odin using the buttons (BL,AP,CP,CSC) AP will take a while, be patient. After all added, hit start and sit back

HELP: Upgrading to EMUI5 on NEM-L21 with TWRP and Xposed

I read here, somewhere, that you need stock recovery to do the update. Since I have flashed another recovery (and rooted and installed Xposed), I'm not sure if I can update to EMUI5.
Furthermore, I'm not even sure how to do the update. The update (b351) is available in FF and checks out as "compatible", but I don't know what the install procedure is. Especially without stock recovery.
Any help or info is much appreciated

yeah, you should flash stock recovery thru ADB and thn try updating...

Not adb but fastboot

That you may need to find your own. Well in custom ROMs, they are designed to work with custom recoveries like TWRP. While in stock, the whole system is inside update.app, which can't be read by a custom recovery.

[Guide] How to Flash Encrypted ROMs on a Decrypted Device (Without Losing Data)

Most custom ROMs for the OnePlus 5 are now supporting encrypted devices only. However, some users choose to keep their device in a decrypted state for MultiROM support and for other reasons. If you follow the steps below, you can flash any encrypted ROM on your decrypted device (without losing data) and your device will remain decrypted! I found this information in one of the many threads I've read (I don't remember which one) and thought I'd post it here to help others and for easy reference. Enjoy!
Follow These Steps:
1. Boot into TWRP
2. Wipe caches, data, and system partitions
3. Flash encrypted ROM
4. Flash GApps
5. Flash Magisk
6. Flash no-verity-op5.zip (not created by me)
7. Reboot
8. Enjoy!
If you closely follow the instructions above, you can enjoy any ROM on your decrypted OnePlus 5 and have the best of both worlds! :highfive:
Note 1: If device gets stuck at OnePlus boot animation after following all of the steps above, hold the power button for 10 seconds to turn off device. Power the device back on and it will boot successfully into the ROM.
Note 2: Some ROMs are not compatible with MultiROM without the inclusion of additional commits by ROM developer.

After wipes, its Flash ROM.. Flash optional Kernel.. Flash Gapps.. Flash No-verity.. Flash optional root (magisk or SuperSU).. Flash optional Viper4Arise?

Is this confirmed working? Has anyone actually tried the process and confirmed that any data on the phone's internal storage is there?

I've found that flashing SuperSU (instead of Magisk) on encrypted ROMs often ends in a bootloop on my decrypted device. Flashing Magisk seems to be a requirement.

Not working for me. Tried with AICP release from 9/11. Wiped caches, system, data. Flashed rom. flashed gapps (tried stock/full/micro). Flashed magisk (also tried without). -> Bootloop
//edit
sorry i think i misunderstood the post. i thought i can flash decrypted roms on encrypted device xD is that possible too?

No, I believe your device must be decrypted to flash decrypted ROMs.

The original zip was modified for making FBE optional by @snowwolf725. Click here to visit his original thread.

I have a quick question. I just unlocked the Bootloader on my Plus 5 and installed TWRP 3.1.1-1 and Magisk 14.0 on it. The firmware is 4.5.0 as I didn't let it update at all and did all this to the device upon first bootup. I did not decrypt.
I've tried installing latest RR release (final for N cheeseburger) and the install stops with errors. I tried a different rom in the same Android version (7.1.2) and get same results. MD5 checks out on both downloads.
Do I have to flash the latest OnePlus 5 update (full OTA 4.5.10) before flashing a 7.1.2 rom? And should I decrypt my device for easier flashing?
If no one answers, I completely understand and will search some more but this seems to be a cloudy subject that gets many different answers and I thought I would post it here. Thank you all in advance.

Yes.. U need to flash the latest firmware and then flash roms.. There's a thread for firmware.. Flash the whole zip would again give you stock recovery and you have to re do the fastboot stuff so makes no sense..

In addition to what is stated here, if you flash Magisk immediately after flashing the full firmware zip (no rebooting between steps), TWRP won't get replaced with the stock recovery. This is a great time saver!

Darn, well thanks for the reply

I just wanted to thank you for this thread. All of the information you provided helped me immensely. I was struggling with this device and flashing roms at first but one I unencrypted it, with your guide, everything worked great. I was going to leave it encrypted for easier flashing since most all the roms for this device are encrypted only. But I was having more issues than ever. And many, of the posts in here have also answered quite a few questions I had. This should be a pinned tread.
Anyways thank you again. Your thread is a must read for anyone with an Opo5.

Stock official ROM for x522 (snapdragon)

I'd like to go back to stock, I'm currently on lineage 15.1. What would be the best method to do so?

darkmen10 said:
Flash this TWRP https://drive.google.com/file/d/0B6Ig1vJFJgpobVVncTFRbjJKQUk/view
Then make a Clean Flash of the Rom
X526 5.8.19s: https://androidfilehost.com/?fid=746010030569971880
X522 5.8.21s: https://www.mediafire.com/?6almos553oh0xg6
If you see Error 7 at the end of the installation, restart Recovery and Flash Again,This is how I did it, I hope it helps you

Does it have to be that particular version of twrp? Because I already have one. Also, why did you post one for a x526, my phone is a x522

darkmen10 said:
Yes, that specific one is used to install the Eui Rom Stock, another Twrp will not allow the installation.Post one of X526 because it does not matter if you have the X522 model, you can install Rom of any X52X model , I have the X520 and the roms of X522 and X526 work fine

It is because it is the rom stock. It is the last 21s. But the truth is better that you install an EUI based rom. I recommend this one based on the 5.9.26s that you can flash with the normal twrp without flashing additional things. It works very well since I tried it a while ago
