Hi guys, ITS done!
UPDATE: 8.5.2015
Today i found the last fastboot command to downgrade.
Now its possible to downgrade from .77 to the rootable versions .53 or .57.
After downgrade and root, its possible to save the su with the root ab and upgrade your device to the newest .77 version.
Thx to the creator of the rootzenfone app!
So everyone who was to fast with the upgrades, can now go back and root the ASUS ME581CL.
I try now to pack all data in an apk, so that everyone can use it without to type. :good:
UPDATE: 9.5.2015
I will post now the steps to downgrade because of guys who want faster the root.
Intelflashtool: https://mega.co.nz/#F!B1lCHKbQ!pHQkVqwBcD5gQkaKhjd1hA
1. Make a backup of your apps with the asus backup tool or adb backup.
2. Copy the firmware .53 or .57 from the asus site and put it on your sdcard.
Rename to MOFD_SDUPDATE. (Look at your SKU ww,tw)
3. Factory reset and boot to droidboot with adb reboot bootloader or vol+ and power button on offline device.
4. Now we are flash the following files:
a. fastboot flash token bom-token.bin
b. fastboot flash dnx dnx_fwr.bin
c. fastboot flash dnx dnx_osr.bin
d. fastboot flash dnx ifwi.bin
e. fastboot flash radio radio_firmware.bin
f. fastboot flash tlv update.tlv
5. Now push vol- button to the point „sd update“ and press the power button. Plug off USB. The device is in Intel SOC mode now with an offline screen. No panic.
The last file to start flashing is the correct droidboot, this will done in next point...
6. Open Intel phone flash tool and choose "custom flash". On upper left choose "systemblankphone"
and click the files we flashed before (radio and tlv not need). Inclusive fastboot.img.pos.bin and boot.img in the lines.
Check the box with on-demand flash mode and press "start flash."
7. Press vol+ and vol- at same time on the tablet and plug usb in your pc. Release the vol buttons and then flash starts. Now its a little bit tricky but you can not brick your device. After around 3 min plug off usb and stop the flash. Uncheck all and let only OS Image actice.
Start Intelphone flasher again with "start flash". After around 2 min plug off device again and stop the intel tool. Now its ready!
8. This point is not really relevant but i push the power button for 10 sec and plug in the usb. Now the tab is charging and the display switch on. Start device with power button and the downgrade to .53 or .57 is starting.
9. Install the root zenfone tool, activate airplane mode and start the root app. Now your tab is rootet on .53 or .57. Open root tool again and look if root keeper is active. So, now you can upgrade to the newer versions. but use only the OTA updates then your root is safe.
I tried many weeks and this methode is safe, works without problems. Asus ME581CL rooted, job is done!
Have fun!
ps. now i will work for a app that can backup and flash nandroid within android. First tests look good.
Thx

Thank you
I managed it to root my Asus ME581C, firmware version KVT49L.WW_epad-11.8.2.58-20141021 with the Intel Atom Root Pack from this thread http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096
First of all i enabled USB debugging in expert mode and copy the SuperSU Zip on the internal storage. Then i installed all USB drivers for Windows. At last i start the launch.bat from the root pack, first type "ACCEPT" in the shell window and then "T3". I got the temp CWM Recovery and flash the SuperSU Zip and restart my device. All runs well now.
But i have one question. My device say, there is a firmware update, and that my files are not get lost if i start the update. Did i have already superSU if i do the update? Did someone tested it?

Hello
You really rooted the Asus Memo Pad ME581C ?
Yep, i attached some pics.
SuperSU installed doesn't mean we gained root. Did you check it with root checker ? An application like titanium or adaway works?
Don't think I have a doubt in your world but till now nobody got root on ME581C (on the contrary ME572C). I receive mine at the end of this week and I'm really interested to root It. I cannot use anymore tab or phone without clean master, greenify, titanium and adaway.
sorry i can't help you
i am an new people
As you can see on the second Picture, i already installed Titanium Backup, and it works. Same with Apps like Lucky Patcher, Aptoide or AdFree. Works all like a charm
Ok, this is a good new, I receive my ME581C tomorrow or friday.
But where did you get the firmware version KVT49L.WW_epad-11.8.2.58-20141021 ?
you didn't update to WW-11.8.2.72 ?
i got my ME581C at the 8th of april. The manufacturing date on the packaging says 11/2014. I think i got a lucky shot with this device The device came with the firmware KVT49L.WW_epad-11.8.2.58-20141021.
I got mine last friday.
First thing I did, check firmware version. It's WW_epad-11.8.2.58-20141021 too.
I tried RootZenFone-1.4.6.8r and to my great surprise, it worked. So, for now, I'm in the same place as you, I don't know if I can update firmware without lost root.
If we can make a backup of system partition, we could reverse by recovery.
besides, tab is really nice and screen is large enough for everything. As comfortable as 10' for a tab size close to 7'. But I discovered some little problems:
- too large to be taken in one hand
- whites are not real white. It seems that colorimetry is too hot. I compared with ME572C which got real clean whites.
- speakers are not as good as ME572C, sound is flat.
On the contrary, the 7' screen of ME572C is too small for comics, games, etc ...
Funny thing, ME581C screen could enter into ME572C. That will be the perfect
root
Hi guys,
Sry for delay. Was busy with study and the new Smsung 920 and 925.
Root is no problem until firmware x.x.65 arrived.
My goal is to root the new firmware x.x.77.
What ive done now is flash the Asus down from the x.x.77 to the x.x.54.
The problem is that after the upgrade, root get lost.
I made a backup off all mmcbl partitions. I flashed all partitions without problems, so if the root is lost i can go back to the x.x.54 firmware.
Anyone know a solution to keep root after the update? Erase Asus the system partition with an upgrade?
So thats the problem su cant hide.
hi guys?
may i know how you guys downgrade your me581cl from .77 to .53?
i tried to use asus flashtools but it failed :crying:

Fine. I post all on the first post.
I think in max. 15min all is done.
But where is update.tlv? I cannot find it =(
Also on step 7 nothing happen and I have 1 unknowns device "MOOREFIELD"...
And finally it's bricked...no any reaction after step 6, only unknowns device "MOOREFIELD".
UPD: strange, but it works ))) Actually update.tlv not necessary. Trying to update via OTA
Nice to hear. I will look for the tlv. But not all files are needet to work, i posted all files what we can flash for the best compatility.
I tried many weeks now for a solution and "bricked" it many times. But i get it always back with this tool.
The main problem was the ifwi file. Without that, no downgrade is possible. And to flash this file, was also not possible.
But now it worked.
You can make a nandroid backup with twrp live or nandroid manager to keep a safe backup.
Hi Guys,
I asked my colleague to buy me a OnePlus 6 from China. I just got the phone but realized that it's running on Hydrogen OS.
Is there any easy step-by-step guide on how to uninstall Hydrogen OS and replacing it with Oxygen OS?
To add to this, I have no experience in rooting any phone before or such technical stuff, so I would really appreciate if the guide is a "for Dummies" kind of guide.
Details: It's 8GB, 128GB version. I live in Sweden.
Many Thanks in advance!
- FLD
First, download (latest) oxygen rom from this forum and copy the rom file into your phone
Then, in system, select 'setting'->'system update', then hit the setting button on the top right corner, select 'local update' and select the rom file
wait for it to finish and it's good to go

As mentioned, I'm really not very technical and would appreciate a more thourough explanation on what steps I need to take.
For instance, a link to the latest Oxygen OS would be very helpfull. Where exactly should I copy the file in the phone? Maybe it doens't matter? So it will just "override" the Hydrogen OS and no need for anything else? I mean, there will not be double OS's on the phone?
Sorry for all the questions, but I'm just very nervous about this.

Sorry for the late reply.
First, download (latest) full oxygen rom from https://forum.xda-developers.com/showpost.php?p=76596831&postcount=2
it's a .zip file, you should copy the rom file into your phone
Then, in android system (not recovery/bootloader), go to 'settings'(of system)->'system updates', this is where h2os/o2os manages otas
then hit the setting button (looks like a gearwheel) on the top right corner, select 'local update' and select the full oxygen rom file
wait for it to finish, reboot and it's good to go
Honestly, you should find a friend who has basic technical skills with Android and Flashing ROMS.
Making a mistake without understanding the foundational skills required, might cause your phone to be unusable. Some assume everyone has the skills needed and no offense, but you sound like you may not have the technical skills to be trying to switch from HOS to OOS. Trust me, if you're not sure, don't mess with it.

Sorry, I just don't have the condition to test that. However, I think in this way you can get your phone on real O2OS, and if you apply another version of full OTA update of O2OS (like 9.0.2) the problem may be solved.
I have buy an OP6 from china too "A6000" launched the OTA update 9.0.0 when it's released here in France, now my phone have OOS and all work fine. :good:
i ordered mine and hasn't arrived yet.
how does one know if it's china version or intl version?
is it on the about phone on settings menu?

Hello showgood163,
I've just bought Oneplus 6T in China.
Is this procedure will also work on Oneplus 6T ? I've found a youtube video telling that after installing the Oxygen OS, we must do factory reset. Is it really needed to do a factory reset?
In my case, my phone is brand new out of the box, and I want to change from Hydrogen OS to Oxygen OS. Should I use the local update method or installing it from Recovery Mode (by pressing power button and volume down button.
Thanks in advance!

I don't have an Oneplus 6t so I can't test on that for now.
However, the rom you download from the official site is not compatible with 3rd party recovery, and there's no `install from` option in the official recovery.
So iv had this device for quite some time now. Updating the phone through the internet doesnt do anything and goes into loop and restarts. So im stuck on this Android version for a long time.
Im a little bit of a newbie when it comes to firmware flashing rooting etc. I am on an Xperia XZ Premium G8141 with Build number 45.0.A.5.1
I already have the bootloader unlocked.
What would be the right steps for me to take in order to upgrade to Android Pie safely? Maybe even root the phone?
Stock Android Pie would be the best option for me i think
So i managed to Upgrade on my own to Android 8
Downloaded firmware from XperiFirm and flashed it on my device with newflasher
Still when i go to system updates it doesnt update. It downloads a 1.5 gb file then restarts and the update is still there.
Any solutions?
Your device is unlocked. OTA is broken. You must flash 9.0 manually. And no there is no way to re-lock the bootloader that I know of. If you would like me to tell you dee way to do that PM me or reply back here

i would like to know how yes. thanks
lets do that here and not over pm so maybe more people looking for something like that could find it also
i would like to have Android 9 Pie and also maybe give it a try to root it.
Iv never done that before and since its not my main device i would give it a go and install some custom apps and modifications.
Ok ? I'm at work right now but once I get home I'll write you up a guide here on how to get to pie, how to flash twrp, how to root phone, and how get xposed if that's what u want or existenze room working.

Do you want volte for T-mobile cause I can make that happen. Also do u have fastboot and adb drivers installed?

im not sure what you mean with volte for T-mobile. If it has to do with networks im actually in Greece and we dont use T-Mobile here. I saw a Greek Android version up to 8.0.0. which i have installed right now
I have fastboot and adb drivers already installed, but the adb driver seems to be giving me some error and exclamation mark in device manager for some reason. The phone is recognised by Xperia Companion for example though
figure out that error. right click on the driver and look in details and report back. An xperia companion should most likely be useless at this point since u unlocked it
Well from a translation of Greek it says "not possible to start this device (code 10)"
Its the Sony sa0116 adb interface driver right? That's the one I could find

First if your phone blows up, freezes, dies or boot loops it is not my fault. I will help if i can but if you blame me. I will not feel bad
First things first Here's what you need!!!
-flashtool- If you can find the xperia ftf downloader only more power to you. http://www.flashtool.net/index.php
-newflasher, This is the correct tool for flashing new firmware on the xz premium https://forum.xda-developers.com/crossdevice-dev/sony/progress-newflasher-xperia-command-line-t3619426
-twrp image: https://dl.twrp.me/maple/
-root aka magisk https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
-minimal adb. Not gonna link it. so easy to search. INSTALL THIS BEFORE EVERYTHING ELSE
Ok here we go to getting to 9.0 and root:
Getting your firmware
-First install flashtool after you download it.
-Once its installed you want to navigate your explorer to where it was installed, and find the drivers folder. Click the drivers exe and it will come up with many options. You want adb and fastboot. I think its the first two. Click install
-Drivers installed? OK moving on! Open flashtool and navigate to xperifirm. Should be on the toolbar. Another window will pop up with a bunch of xperia phones and years. Find your phone. click your region. In the right screen of the window it will show what firmware is available. Most recent pie version will end in .24. If unsure, GOOGLE THE FIRMWARE NUMBER.
-CLICK ON THAT FIRMWARE AND IT WILL BEGIN TO DOWNLOAD. after download it will unpack it
-Once it unpacks and finishes, close the download window. Close xperifirm. Dont touch flash tool. Leave THAT OPEN. Flashtool will then unpack the ftf (which is important that it does) and the bottom bar will have progress bar. It will be clear when it finishes or fails but you will see red letters if it did.
-Firmware unpacked? Great! Extract your newflash firmware. All items in the zip must go into the folder where your firmware was downloaded. Mine looks like this C:\Users\rocke\.flashTool. It will be in the download folder and it will have your unpacked firmware. Go into that folder and it will have a bunch of files from your ftf. Move your new flasher files in there. Make sure boot folder is emptied into the main folder where are the others are and new flasher. Delete boot folder.
Flashing time
-hold volume down and plug in phone to pc. Green light should come one.
-Open Newflasher.exe
-a few questions will appear. I dont type = yes on both questions cause its kinda pointless unless you need gordon gate drivers and u want to back up something that i think i dont need/
-WHoooooosh! Command lines will start popping up and your phone is being flashed. Let its do its thing
-Eventually it will tell you you can disconnect your phone after u close the window. Boom android 9
Give me the root captain!!!
root.....a dangerous but such a fun little thing
-first your twrp. Hold volume up and plug in phone. Blue Light will come on. the twrp image must go in the minimal adb folder. Other wise adb will think your crazy and say it doesnt exist.
-type this in minimal adb fastboot devices. it will show if a fastboot device is available. If not we have problem with drivers. If yes. Then we keep trucking on
-flash twrp. type this command in fastboot flash recovery twrp.img (rename image obviously) It will flash it to the phone.
-Reboot phone into recovery. Volume down and power button. Release at sony logo or it might be the unlocked bootloader warning. Cant remember. Either way release power button on that logo and keep holding volume down.
Boom your in twrp.
-if magisk wont move over to your sd card in twrp. its time to adb push
-adb push magisk.zip /sdcard
it will move the file.
-Find where you pushed it and install magisk. It will do its thing.
If you followed the instructions your phone should be rooted and you want need a drm fix to cover the holes of the BL unlock. If hit any snags message me or reply here
Thanks for taking the time to write this.
The first part of flashing Android 9 I already know how to do. As I mentioned I my second post in this thread I already upgraded from Android 7 to Android 8. My problem was that XperiFirm doesn't have Android 9 for my device and Android 8 is the latest I could find to download. I would have already flashed Android 9 otherwise
As for the rooting part I will have a look when I'm back at home
Sent from my iPhone using Tapatalk
Yes I understand that. If you want 9 u need to use xperiafirm and get a different region that has access to it. If you use Greece ftf that is still on oreo. Chance is you'll be on 8 for a long time
I'll try and find one with Android 9 then when I get the time to do that. Also pretty busy with work

ce1 matches the europe basebands. that i know is for sure on 9.0
i think i will give a try to a custom Rom instead like this one :

guys i really need help,my youngest son bought a used op7 pro but for some reason its on Beta and he wants it to go back to ota.I tried following the guide but i cant get it to work.The option to install via adb or extern never shows up in the phone when you go in recovery mode.I really don´t know what i´m doing wrong.
Try to put the Dowgrade version for local improvement that will leave it em and clean ... then you accept OTA to the current version and ready

What version of Beta is the phone on?
If the beta is newer than the current stable I am not sure if you can switch over until the release of the next higher security update on stable
If the phone is older than beta18, then you should be able to switch over.
I have done it twice, the only difference is the procedure if the phone is stock or rooted/TWRp recovery. Both times did it through a local upgrade by downloading full (2+ gb) firmware from the 1+ support site and placing the download in the root directory of the storage on the phone. Doing a search online should provide a procedure to follow.
Beta also receives updates, personally I have tried beta 14 and beta 18 and prefer them over the stable 3.4.2. and 3.4.5.
I find there are more options with beta.
I can't do that,it says that it's a downgrade and for security reasons it will not allow it.So that way it will not work

you can use
https://oxygenos.oneplus.net/Fulldowngrade_wipe_18821_190425_0253_user_fix_revision_MP_release.zip
to go to OOS Android 9.0 and flash any stable official ROM from local upgrade
Install the downloaded ZIP as a local system update:
1. Place downloaded ZIP in root directory
2. Settings >> System >> System Updates >> (Cogwheel at top right)
3. Select downloaded zip file.
4. Install and restart.
Everybody knows that after upgrading to C_07, we lost access to mtkclient, root, and many more, and Oneplus support sucks.
So, this guide will help you go back to Android 11 and back to root.
This rollback install will wipe all your data, so make a backup first. I did it on my own device and took the risk of bricking it, and I did it once because I'm not nuts to do it again. Only do it if you are comfortable. I'm not responsible for any damage to your device.
I was on C_10 (Android 12) and downloaded the rollback package for Android 13 from https://community.oneplus.com/thread/1267587167833030657 (I posted the links from the source below because Oneplus has the bad habit of removing the links). Download the appropriate file to your device. If you don't know, you have to download all three and try them.

Go to update, and if you do not see the local install, you need to go to the build number and click seven times to enable developer options.
After downloading, rename the file to oplus_ota_downgrade.zip. Go to update, select local update, and install this package. When the install finishes, the device will reboot and will be wiped. After that, you need to configure your device. At this time, the device will be on C_09.
Go to update, and a third option will be available, the option to join the beta or something like that. Click on that, and after requesting to join the beta test, go back and click again on update, and a new update to (Android 13) F.45 will show if I remember correctly. Once done, download the rollback package to Android 11, available on https://www.droidwin.com/downgrade-oneplus-nord-ce-2-from-android-12-to-android-11/.

ROM EU: https://oxygenos.oneplus.net/oplus_ota_downgrade_Rollback_EEA.zip
ROM GLO: https://oxygenos.oneplus.net/oplus_ota_downgrade_Rollback_GLO.zip
Remember to rename it to oplus_ota_downgrade.zip. Go to update, select local install, and choose the zip file. After applying this update (which will take more time than before, it looks like it's broken at 94%, but just wait), the device will be wiped again. Done with the setup again (now you are on A_13 Android 11), power off the device, and press Vol- and Power, and you will have access to fastboot. Yes, now we have fastboot back! On a computer, plug in your device (supposedly, you had installed drivers before).
Execute:
fastboot devices
And, if it returns something like this: SOMERANDOMCARACTERS(Serial number of your device) fastboot
Execute:
fastboot flash preloader preloader_oplus6877.bin (this preloader is attached to this post).
And you're done! Now you can use mtkclient again. Just remember not to update your device until we find a way to keep the preloader vulnerable to the mtkclient exploit.
Thank you so much for posting this!
Hi @brunowm perfect guide... and thank you in advance for your patience and understanding as I am not an expert on these things and I only want to rollback to Android 11... few (perhaps silly) questions (I am in android 12 build number IV2201_11_C. 10) at the moment:
- do i need to be connected to wifi when doing these operations?
- What am i doing wrong that sometimes goes to "safe mode" and I can't get it out from there at all, only by trying to install the rollback (which fails, look next).
- I wish to understand better why when I try directly to install this: oplus_ota_downgrade_Rollback_EEA.zip (your second set of links) it starts installing but stops at 16%, then reboots and says that the update failed. Is it because of missing the beta installation that you pointed first?
- However, I tried with the beta file (21342_Beta1__downgrade_ota_CPH2409.zip) but the verification fails.... it says that package is not compatible with your system ... could this be because I am in Android 12 and this is the rollback from Android 13? Nonetheless you do mention this situation, so I am a bit confused :-(
- Also, it seems that one of those downgrade.zip files helps you to downgrade first from 12.1 to 12. This file is verified, recognized but similarily to the one that goes from 12-->11 it stops at 16%, reboots and then it shows message that it failed...
I'm really desperate so, any light at the end of the tunnel is highly appreciated!
ps.
- is there any possibility to rollback to earlier oxygen versions for example 1.2 or so?

Very quick question, do you think now is possible to downgrade this device from Android 12 ->11?

Hi, you have renamed the downloaded file 21342_beta1__downgrade_ota_cph2409.zip to oplus_ota_downgrade.zip ? It's better doing with internet (wifi or 5G) off. After this install you will be able to update to Android 13 and from this version (F_45) you can rollback to Android 11
Hey @brunowm, I followed your first step and was able to roll back to C_09. However, there are no available beta programs to update my phone to Android 13. Should I bite the bullet and proceed with step 2 or is there a known issue that the second step will not work with Android 12?
Hi, I just wanted to give an update @brunowm . I was able to downgrade the OS to C_09 from C_10, by following your first step. However, the option to join the beta program is not available to me, hence I cannot join the Android 13 beta yet.
I can't execute your second package since I am experiencing the same issue as @k.whatamidoing where the downgrade terminates at 16%.
Do you have any idea if there is any criteria I need to meet for joining the beta program? I have already enabled developers option.
