[ZenFone 2 Q&A, Help & Troubleshooting] audit13:
THANK YOU, THANK YOU, THANK YOU! It worked.

This is what I did to cause the loss of serial #:

used the sd card method to downgrade from MM based on instructions from another forum (i.e. not XDA);

phone got stuck at the erasing portion of the process and stayed there for about 45 minutes so I powered off the phone;

used xFSTK to successfully flash the bootloader

successfully flashed MM raw file with Asus Flash Tool;

tried to downgrade to LP again and bricked again;

used SFSTK again but serial # was now abcde... in bootloader so I used Asus Flash Tool again. AFT never finished flashing a ROMand the phone was stuck on the bootloader screen with "Result: okay" so I just shut down the phone and left it off until I saw your post this morning.

Edit:

I set up the phone ran software update option from settings but the Android Version is 5.0? Also, when I boot into fastboot, I see the serial # as abcde... but I can get the proper serial # by pressing the volume up and down keys a few times. Lastly, my SD card is not seen in recovery but is seen in the ROM. When I boot to recovery from the bootloader, I see this:

Android system recovery <3e>

LRX21V.WW-ASUS_Z00A-2.20.40.198_20160930_8756_user

E:file path /tmp

Finding update package

Opening update package

E: file path:/sdcard/MOFD_SDUPDATE.ZIP

E: failed to map file

SD installation aborted.

E: Installation failed with status 1

I'm not too worried as these things are cosmetic. The important thing is the phone now works :)
[ZenFone 2 Q&A, Help & Troubleshooting] timbernot:
Just to clear things up.

You never bricked your device using the method in the OP regarding downgrading via sd card. So not to scare people off .

Mofd sdupdate method is for adb sideload using a cable.

In the video it shows how files must be written when downloaded for each stock firmware in file manager in the first few mins. To be recognised from ext sd

Lastly , 2.20 in firmware or raw = LP

4.21 = M which doesn't have a raw yet unless I missed it coming about
[ZenFone 2 Q&A, Help & Troubleshooting] audit13:
Correct, the method I used was from another site. It was NOT your method from post # 1 that bricked my phone.

I was going to try your version to downgrade but the option to apply an update from the SD card is missing in my recovery options.
[ZenFone 2 Q&A, Help & Troubleshooting] timbernot:
On LP recovery there is no update by sd, in M there is ;)

You are in 5.0 so no need to downgrade.

You will get notification to update after a reboot , if firmware is on ext sd card , written like shown in file manager in video.

You are on the last .198 firmware so it will require M firmware to get notification.

Also , you might get notification for the downgrade version 52.20.40.196 if on ext sd card , written the same it is in video.

;)

Ps, I do get notification of 52.40 which is 2.20.40.196 when set up, and I'm on .196

already.

I'm about to go out now , hope you have a good idea now.

Shame , its nothing to do with downgrading via sd but just general knowledge :good::good:
[ZenFone 2 Q&A, Help & Troubleshooting] audit13:
Thank you for your help. I got all confused with firmware versions. I even unlocked the bootloader so now I get the white screen with black text lol.

You are a life saver to me :)

Edit:

I copied the latest MM zip from Asus and placed it on an SD card. The ROM detected and installed the ROM update and, after the update process, the phone was running stock MM with a locked bootloader.

I then used the method from your post (post #1) and was able to downgrade to LP with no problems at all this time and it's all good :)
[ZenFone 2 Q&A, Help & Troubleshooting] timbernot:
Marvelous stuff and thank you for taking time out for testing and confirming ;)

Modder tool by giovix in general section unlocks M , flashes twrp and root.

Just remember to use "return to stock" in modder , flash, Boot.img, recovery in modder..before downgrading to 5 and you will avoid bricking ;)
[ZenFone 2 Q&A, Help & Troubleshooting] audit13:
I used the modder tool with stock MM and it softbricked the phone on me in that it kept rebooting itself to a white screen after running the bootloader unlock option. I eventually got iFSTK to flash a temporary bootloader and then used your suggestion of opening, closing, and re-opening AFT to reflash a stock ROM. You saved my phone a few times over the past 2 days :)
[ZenFone 2 Q&A, Help & Troubleshooting] timbernot:
I think the tool should be used with .134 M , the first M ;) to unlock Boot loader

There was a trick too , to whip out the data cable before it reboots to white screen .. Then power off ,power on insert cable before it reboots , proceed in modder ;)

14.1 N is based on mm.134 too with added tweaks from .144 and .184 M ;)..just that dev jrior is or was waiting for device repair to update rom

recovery mode not working

Hi,

I just try your process to downgrade from ressurection remix 6.0.1 (MM) + twrp-3.0.2-0-Z00A to stock Lollipop rom UL-Z00A-WW-2.20.40.198-user.zip

What I have done: thanks to modder's bat option "return to stock option" I flash first the boot and then the recovery. I get a successful message each time but I never succeed in running the stock recovery, it "bootloops "...

So I install again twrp thanks to adb fastboot flash recovery and I am able to boot in twrp recovery.

I don't know what I missed :(

In advance thank your for your help guru!

If want to downgrade after follow OP

Ps, to downgrade ,use 52.20 . 40 .196 like shown in OP
[ZenFone 2 Q&A, Help & Troubleshooting] Justfabi1:
Thanks a lot for your quick reply.

I follow the first steps again with modder but unfortunately I never get the "dead android" after choosing the recovery mode, I only get the white Asus screen and then it reboots.

I noticed for the versions .134 and .196, thanks!
[ZenFone 2 Q&A, Help & Troubleshooting] timbernot:
after return to stock, flash boot , recovery ..remove data lead.

Scroll to power off in boot loader.press power..Leave ten seconds before using power and vol plus to get to boot loader again

Follow what's already described above again

Ps , can you give link to rom you are on ?

Are you on MM bl version or M based on .165 LP ?
[ZenFone 2 Q&A, Help & Troubleshooting] Justfabi1:
What did you mean by "remove data lead"? Are you talking about the option nÂ°9 "erase /system /data and /cache"?

I think I am gonna flash another ROM from twrp.
[ZenFone 2 Q&A, Help & Troubleshooting] timbernot:
no link there btw

I haven't delved too much into it but judging by what I just read here regarding date of build http://xdaforums.com/zenfone2/development/rom-resurrection-remix-m-5-6-9-t3399795/page74

You may have been on LP based M rr based on lp

And using modder tool may have done more damage than you think because it is built for only 6.0 with MM BL

You may get lucky .

When you have unravelled the mystery.

If you are on 6

You can downgrade following the OP ;)

Hi Timbernot,

I finally succeed by doing this as I was still with the LP bootloader :

- get the boot.img, recovery.img and system.img

- wipe data/cache

- in fastboot mode I use these commands:

- fastboot flash boot boot.img

- fastboot flash recovery recovery.img

- fastboot flash system system.img

- the phone reboot in stock ROM :)

Thanks again!
[ZenFone 2 Q&A, Help & Troubleshooting] timbernot:
Good stuff glad I helped you ;)

Before you do anything else like upgrade to 6 , proof in the pudding will be a factory reset in settings ;)

hence why quick sideload was advised.

Once you get to 6.0

Maybe try downgrade via sd card , what this thread is about (supposedly) and let me know your results here ? ;)

hi sir I'm harrispk in the xda developer, idk somehow i cant reply to your thread. anyway this is the link to LP .144 http://dlcdnet.asus.com/pub/ASUS/Ze...-user.zip?_ga=1.66522150.904626520.1479736325 . thank you﻿

Ok, i`ve established which phone you have :good:

Problem now is -- you got the .144 correct for Z008

But i`m having trouble finding LP .196 for Z008

If you have LP .196 on your device then it must be a Z00A

Unless ASUS withdrew it from here,

Unless you know what you are doing and dont know what device you have , please dont do anything to your phone.

[Huawei Mediapad M3 Questions & Answers] sselpeelsxx:
Hi M3 users,

I'm a long time lurker and reader on XDA. Now it's time to give something back or at least participate :)

Following my recent M3 purchase a dugg a bit deeper into this topic and tried to get us the stock recovery for our devices.

I'm not really a dev. I just used the information I found here and in the russian forum where greatslon (thank you guy) is posting his work.

If you find an error in the process please let me know. The files have not been tested in any way. I have no idea if this would even work (encryption and so on).

So I managed to extract the recovery.img file from the chinese rom. This method will also work for the LTE variant.

Maybe [MENTION=4273212]greatslon[/MENTION] or [MENTION=4008653]somboons[/MENTION] can share their view on the topic or maybe [MENTION=4008653]somboons[/MENTION] can even use it in his tool.

[Huawei Mediapad M3 Questions & Answers] Slavon-93:
Don't quite understand what's this for. First of all, recovery should be the same version as your ROM. I don't know if their mismatch will immediately lead to some malfunction, but some people on 4pda said they should match. Second - stock recovery's functions are limited to factory reset (wiping data, cache, etc.) and installing OTA updates. Without changing OEMINFO (and it's still unconfirmed), you won't be able to install any OTA except those, intented for your model and region, so again there's no need to install a higher version of recovery than your ROM is. But anyway, thank you for the extraction instruction.

P.S. I think there's no need to flash both recovery and recovery2. Recovery2 can be successfully replaced with TWRP and this combination is really great, cause you can launch TWRP by holding Volume Up button only.

And the only reason why you should keep recovery original is that it doesn't really wipe /data - it also creates some files there like custom.bin, containing your regional settings.
[Huawei Mediapad M3 Questions & Answers] sselpeelsxx:
Hi Slavon,

Thanks for your highly appreciated comment. [MENTION=4008653]somboons[/MENTION] was looking for a stock recovery so I thought this might help.

Your given information are really helpful. I did not know that you could flash TWRP in recovery2 and replace erecovery :) Handy information.

I'm pretty new to the Huawei structure so always glad to learn something.

Giving Back

Benjamin,

I've also been a long time XDA lurker. Most of the devices I have owned were mainstream and thus already had a very active XDA developer community; Even if root had yet to be achieved, there would be hundreds of messages on the topic.

It seems the Mediapad M3 is just getting started. I am a developer of over 20 years, but very little android experience. However, I have recently spent a considerable amount of time (about 50-100 hours) working with the low level ADB protocol source code. And I have rooted and flashed no less than 50 devices, everything from cell phones to Android TV devices to routers.

I'm going to take this device on as my first real dev effort in this arena.

I have a few goals:

1. Get working backups for people that soft-brick or need to revert (including myself).

2. Recompile TWRP for the M3 to confirm greatslon's work, and better understand the process.

3. Release a stock rom that's pre-rooted and cleaned up (not that there was a lot of bloat on my device).

4. Release a custom rom that's not MIUI (perhaps based of CyanogenMod).

Since I have virtually no experience, I am sure these goals are quite lofty and will take some time. But hey, you got to have a plan, and I don't have anything else to work on right now.

Let me know if you want to work on anything together, or if you need any help with anything development related.

- 0D0A
[Huawei Mediapad M3 Questions & Answers] sselpeelsxx:
Hey hey 0D0A,

I totally agree with you regarding the backups, I think once the first OTA update is pushed for the EU and US devices we have a good and safe way to go back.

Especially the US owners are struggling with greatslons TWRP version, that's the first thing we should tackle after the backup topic is cleared

I will contact you regarding possible work :)

Best regards,

Benjamin

can flash twrp via fastboot but get error saying and no recovery

hi, first thanks greatslon for doing the work on m3.

i seem to have succeeded in getting stuck and can't get it to boot into your custom twrp. adb on linux was working fine, but no longer. ditto for fastboot just get "waiting for devices" now. i switched to win10 and installed the hisuite app so i can use fastboot but still no adb. so i have tried to flash recovery and recovery2 but when i try to boot recovery i get error "Func NO: 11 (recovery image) ERROR NO: 2 (load failed)."

i then downloaded your custom rom and tried to flash the boot for that still no luck. i can't use adb so i am not sure how to just flash the custom rom with fastboot without being able to get into any recovery.

i did have this all rooted and working with your twrp but kept having issues with dpi and there was an ota update (b003) which wouldn't apply. so i tried to restore backup and it wen't south from there. basically now can't do much other than see the unlock "can't be trusted" page and bootloader.

any suggestions?

Desperately need stock recovery img, not sure exactly what when wrong, but it is stuck in a horrible boot loop. Tried Benjamin's recovery files and they seem to remove twrp and put it somewhat back to normal, but can only access the emui recovery and that fails to load the files. Put twrp back and tried greatslon's ROMs, they load but goes back to boot loop. Wipe and format everything, install my original backup through twrp recovery, it says it works, but again, back to boot loop... at this point I think I'm dead... any ideas, any word on the official recovery img? anything?
