I MEAN NO HARM AND DON'T WANT TO FLOOD THE FORUMS BY CREATING ANOTHER THREAD. I COULDN'T FIND A CLEAR TUTORIAL FOR REVERTING BACK TO ANOTHER ROM FROM H2O 2.5.1. SO I MADE THIS.
MY ORIGINAL POST OnePlus Forums
Just wanted to let know that I managed to revert back to CM 14.1 Official & OOS 3.1.0 without problems!
First make sure you have a terminal made EFS backup & TWRP made /persist backup!
Make sure you have made those before you flashed H2O 2.5.1.
If you don't have a valid backup, I really don't recommend following my steps in any way!
WARNING DO NOT FOLLOW MY STEPS IF YOU DON'T KNOW WHAT YOU ARE DOING!
IF YOU IGNORE THIS AND DON'T HAVE BACKUPS, YOUR PHONE WILL BE NOTHING MORE THAN BRICK!​
WHAT I DID
- Make sure you have a custom recovery. I'm using HybridRecovery_v3.4.imghttp://forum.xda-developers.com/one...0-2-hybrid-supports-oos-t3362904/post66466393
- Make sure that OEM unlock is enabled under developer settings in your phone.
- Make sure that ADB debugging is enabled under developer settings in your phone.
- Connect phone to PC and grant permission to communicate with your phone.
- Grab your modemst1.bin & modemst2.bin files and put them in the same directory where ADB is installed/unpacked.
- Boot phone in bootloader/fastboot
- Start a new ADB session
- fastboot devices
- Check if any device is recognized
- This is the moment where you still can return to H2O.
Side note: H2O 2.5.1. is a fine OS and worked great for me. Maybe I'll return to it some day, but for now I'll be using CM 14.1
LET'S BEGIN
- Fastboot erase modemst1
- Fastboot erase modemst2
- Fastboot flash -S 512M modemst1 modemst1.bin
- Fastboot flash -S 512M modemst2 modemst2.bin
- Unplug your phone and then turn it off you by holding the power button
- Boot your phone into recovery
- Restore the /persist partition with TWRP/HybridRecovery
- Flash a ROM
One thing to mention is that when I restored a backup of CM 14.1 my data connection seemed forever lost.
I managed to fix that by deleting my network settings in the "Settings" app of Android. I also rebooted in recovery and deleted Dalvik/Art cache & cache.
Reboot your phone to system.
Voila, your phone is reverted and both of the IMEI's are still intact!
Any questions? I'll try to answer them as quickly as possible!

Just FYI, I flashed back to OxyGenOS 3.1.0 and it works perfectly fine!
The last numbers proof it.

Hi,
Thank you for your thread.
I am assuming this tutorial won't apply if I already erased my modemst without taking a backup? Because if I were to backup anything now it would just be an empty file?

So sorry to hear that. Indeed, you will have a empty file.. You never made a Nandroid backup? If not, this is a hard lesson you have learned to read always the threads about flashing stuff for the first time. It's always mentioned that you have to make sure you have a full Nandroid backup.

Hi,
You can't edit a IMEI. At least, not that I'm aware of. I've read that people used a HEX editor but not sure how that works or how much time that costs.
My thread is only for people with a modemst1.bin/modemst2.bin backup made through terminal..
However, there is a new guide for people without a backup, but think it's applicable if you haven't used the "erase" command.

hi,
I have a problem with my huawei nova:
i wanted to root my huawei so i flashed the update supersu , and when i restart my phone i have a bootloop....
So, i wanted to do a wipe cache but it gives me :
"Failed to mount 'cust' (Invalid argument)"
But i can no find any cust.img or update.app that want to work because when i want to update my huawei with a update.app (with a recovery stock obviously), the load is only up to 5% and it gives me an error...
1 week that my huawe still does not work...
But before you had flashed twrp?

With me the same error in the recovery menu. I hope there is a solution to solve the problem. My mobile is dead: (, I forgot to make a backup and with the CAN-L11 backup I can unfortunately not start anything because against the conclusion at 99% restoration the following message: "Failed to mount 'cust' (Invalid argument)"
Already several attempts made recovery to flash again.
Please help

Thanks, / cust I now can fix this, but it failed on the wipen the internal memory. It is successful done, but when I look back then into the recovery are the files like / superuser there, I have played the wrong SuperSU and thus my mobile phone can not start after Restore Backup, because this SuperSU does not remove the bootloop remove.
What am I doing wrong? What can I do for my mobile phone to work again and finally start normally?
Please ask for more help

You only made a backup after you installed the wrong SU?
The problem is I have the backup from here in the forum taken, the CAN-L11 and have this successfully flashing, with your help (/ cust). But the other problem is simple I can not wipe anything and erase in the recovery because I had before all the problems, the superuser had installed, another source and since bootloop.
This binary I can now however no longer delete, so my mobile phone normally starts after successful flashing of the CAN-L11.
Recovery shows that it is deleted successfully, but as soon as I reboot into the recovery are all deleted files again there, thus also superuser.
I'm desperate
How can I delete and reset everything, so that my mobile works again?
You are mounting the partitions w/r when you wipe?
Yes I did, but why does not it work?
I'm still desperate, it simply does not work, mount and superuser remains, after delete.
Please, who has a suitable step by step guide which I can still make?

Supersu must be hiding somewhere else also, allowing it to come back. Try browsing around and see if you can find any other files associated with Supersu. Also, I would check the official Supersu thread, I believe they have an uninstall zip that should work and/or can probably guide you on what you need to do.
See if this works:

Thanks, but unfortunately still the same problem
The international memory remains immediately after wipen, etc
Superuser simply does not want to disappear, it can not make my cell phone anymore.
What exactly did you flash? I am guessing you flashed system again and it still was the same? Maybe someone can give you a zip of system to flash, that should erase it.
I would also suggest again heading to the official superSU thread and asking about your problem.

I recognized the same problem. And i figured out. I can delete only one file at one time and then must go back and reboot recovery again when deleting files from system partition.
@Xelfmade perhaps you can check this?

exactly that was what i did... Flash via fastboot
What should I now flash over fastboot?
Can one of you make an order as I tackle the whole problem?
Mobile still does not work and there are always errors that can not be written at once / Data, though mount.
Please really help, my mobile phone is totally broken with the software.
It's no fun just to go back and forth between Recovery and Fastboot.
Please provide instructions and help.
Bootloader is open but TWRP is giving ERROR1 when trying to flash Root, and also is unable to mount any partition...
Any help from someone who managed?
***Important Update!*** I am almost sure the problem is with Huawei shipping the P10/P10Plus with different storage chips.
Myself unfortunately got the eMMC chip + LPDDR4 memory. This is why TWRP is unable to mount any partition since the .fstab is different.
I have a working TWRP I ported myself which I was able to rebrand with, root yet to be confirmed. If you need it PM me.
I strongly advise anyone trying to flash TWRP to check their storage chip first using adb command "ls /proc/fs/*".
If you get mmcblk your F******, SD or UFS you are good.
I have an AL00 (rebranded to L29) that I rooted without too much hassle. The key is NOT sliding the first screen in TWRP. You have to click the read only button and then flash the phh nocrypt root zip.
Thanks!

https://www.gizdev.com/root-huawei-p10-p10-plus-install-twrp/
If you follow this guide exactly, you'll be rooted without issues. (you can use their files, they work fine) Two things to watch for :
1. You absolutely cannot slide the first slider in TWRP to allow modifications. You have to click the read only button.
2. It will only work on a fresh install / fresh boot.img. If you've already allowed modifications within TWRP, you're stuck. You have to flash a new boot.img or completely re-install EMUI via update.zip or funkyhuawei.
Hope this helps
Thanks so much for your Info Goronok.
I got the same problem.. No possibility of a full root and system partition is write protected..
One question:
Is ist possible to do a factory reset out of the settings as well?
Or do we have to go for the funkyhuawei method?
How can i update.zip the system if its not possible to make a dload folder in the root folder on system partition?
Can someone uplad the boot.img for VKY-L09C432B130, if that will save the problem too... ?
Ok that wasnt one, that were 4 questions.. but thanks so much in advance
Kind Regards
Dennis

1. No factory reset within the device will help you once you've swiped to allow modifications within TWRP.
2. I did funkyhuawei, so it's the only thing I can speak to. This method will absolutely work assuming you dont mind spending a few dollars and have a router where you can specify DNS.
3. update.zip should (in theory) work from sdcard, though I have not personally tried it. I think most of the people mentioning this method are coming from a P9/Mate9, which does things a little differently.
4. I have not seen a link for VKY-B130 yet, but here is one for B124. The boot.img here should work just the same... http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1475/g104/v82453/f2/full/update.zip
can't figure out what is wrong
First time I tried to root I did slide the "allow modifications"...
I reinstalled stock twice with FunkyHuawei but still can't get TWRP to work.
It seems it doesn't have access to any partition.
Phone boots normally though...
Any ideas?
Please.....

Hey Mosquito, i guess we both have the same kinda Problem.
I will do the following steps today and let you guys know, if and how it worked out.
The only problem is, im not at home right now, so i dont have access to a router where i can change the DNS. So no FunkyHuawei method for me.
I will do the following steps today:
1. Donwloading the VKY-L09C432B130 jus now. Trying to flash the original boot.img and do the TWRP and root again, WITHOUT swping the TWRP allow modifications slider
2. If No 1 doesnt work i will copy the download update.app, will create a dload folder on my external sd card and copy update.app in it. Then trzing to freshly install the downloaded firmware.
3. If there is somehow a failure or any error with the automated update i will factory reset the phone via settings and then see whtats going on.
I hope everything will work out fine, even without the possibility of FunkyHuawei Reset.
Keep in mind that there are two types of TWRP online available for the P10Plus Version 3.0.2.2 and version 3.1.0.0.. maybe the root works different with the different TWRPs. At this moment im not quite sure which one i use.. probably the one from gizdev, what Goronok told us to use.
I keep you up to date whats going on!
Thanks guys

Dennis

I already did everything you wrote, still no go.
Please update me if you get a different result.
Tried both TWRP versions.
What firmware you had at first?
I have bought my phone 10 days ago.
From T-Mobile Germany.
VKY-L09 6GB Version, Single Sim i guess.
Not sure what Firmware i had when i bought it, cause I immediately tried to root after buying, without checking the FW Version.
But I did a FunkyHuawei Restore before with VKY-L09C432B130 Firmware and it worked.
Only the Full Root is the Problem right now.. damnit.
I Will try everything and let you know.
Later!

I have the Firmware L09C432B130 and i downloaded from here:
http://www.stechguide.com/download-huawei-p10-plus-nougat-firmware-update/
Just google your firmware and downloaded.
You need the exact 100% same boot.img from your installed firmware.
Then it will work for sure!

Dennis,
Can you please check for me if TWRP mounts partitions correctly for you?
I suspect the problem for me is incompatibility of the available TWRP with the Chinese version, or some sort of data encryption embedded.

TWRP is an open source, community project. TWRP development is done by roughly 4 people at this point. We also have a large support community with many people who are willing to answer questions and help people with their devices either through our IRC channel or on forums like xda-developers.
Team Win was originally formed to work on porting WiMAX to CM7 for the HTC EVO 4G. After our work on the EVO 4G we wanted to work on a project that would work on more devices than just the EVO 4G and we settled on working on a recovery. Today TWRP is the leading custom recovery for Android phones.
A custom recovery is used for installing custom software on your device. This custom software can include smaller modifications like rooting your device or even replacing the firmware of the device with a completely custom "ROM" like OmniROM

Go twrp recovery and do advance wipe and flash os then.Connect to pc and copy files to memory card and then.Flash it from there since your hang issue will not affect installing.It will solve all problems.Always keep backups before doing anything.

Your partition got messed by installing custom rom.This problem is uncommon.I cant find good solution for m2 in xda or any forums.Brother just bricked your phone.These cases occur when wrong kernal flash,flashing radio etc.I found this problem only in one plus.
Check these before doing anything in adb
Properly detects the device to avoid errors
Detect if bootloader is locked and temporary unlock it if that is the case.If it temporarly locked again,got to fastboot and unlock it as you know the process.
Try Perform this:
Flashing twrp recovery.img.If no error comes flashing custom or
Twrp is unable to create new partitions...Then
Fastboot boot recovery.img (of stock flyme)
fastboot flash recovery boot.img
Going to stock rom is only nice way i think so.
Boot.img can be found inside rom zip of flyme.Go for flyme first.
It isn't the best method to flash a different rom, but as the cmd implies its perfectly fine for flashing an update of the same rom.Since phone is prime important now.Go back custom then.

how to recovery install meizu m2 mini flyme 6.2.0.0g
thanks sir.. i wanna install this twrp
Pretty good!
First off, a HUGE thank you to @autoprime (for paving the way) and @waylo (for his assistance on getting this going after I found the KDZ)
I am currently storing these in my google drive account, so please be gentle till I have a better host location:
Below are the downloads for the LG-H83020N firmware
Folder with all the LG830 firmware I have so far:
LG830 (G5)
LG-H83020N-Flashable.COMPLETE-ARB01.zip
As always, COMPLETE is 100% stock
Flash COMPLETE zip -> wipe cache partition -> flash Magisk ZIP (or SuperSU if you insist) to root and keep TWRP
OPTIONAL: After flashing, remount /system RW -> delete recovery-from-boot.p to guarantee TWRP sticks
LG-H83020N-Flashable.Bootloader-ARB01
LG-H83020N-Flashable.Modem-ARB01.zip
LG-H83020N-Flashable.Boot.zip
H830N_00_1017.kdz (HUGE Thank you to @Azul Baseem for the upload)
For instructions, follow the same instructions as you would in any other KDZ/ZIP thread. For Example
Feel free to hit thanks.
Also feel free to hit up autoprime's All in One thread HERE
Thank you very much bedwa!
Kdz link updated!
Thank you @bedwa as always.
I fear my only true contribution here is MD5 confirmation of the files:
LG-H83020N-Flashable.COMPLETE-ARB01.zip 8a49733028bef23d775bf542eb62b726
LG-H83020N-Flashable.Boot.zip ddea9d814f66266de34a154f0c7f6b41
H830N_00_1017.kdz 732b717af8d77501342be445002c4fae
Edit: Also, since someone will definitely miss it in the title, this is confirmed to still be on Anti-Rollback 1. You're free to flash back and forth between 20A if you need to Dirtycow your phone again.
Keeping me honest, I swear I'll remember them next time.
Thanks for the upload. I was able to update just fine thanks to this.
BTW... It still has H83020m mentioned in the body of the OP instead of H83020n.

running 20N , so far so good, just notice a small problem with GPS , it is a bit spotty today. @bedwa : Can you make a slim down version ? like removing LG/TMO/Google stuffs ? and reduce /system partition size ?

That would be trickier. All of these are the partition images. To make a slim zip like that I'll have to either unpack and build or unpack and attempt to repack. I might, but not likely at this time.
Thank you so much for making this. So happy to be rooted and on the latest build thanks to your hard work. =)

Quite welcome... It's more time consuming than hard work, but the appreciation and thanks is greatly appreciated as well.
@bedwa
I am running on rooted H83020a with TWRP and SuperSU installed. In order to upgrade to 20N by keeping all my current settings and data along with root and TWRP, what are the steps should I follow?
1. Take a complete backup using LG Backup
2. Boot into TWRP
3. Flash Complete Zip (H83020N) from TWRP
4. Flash SuperSU Zip
5. Reboot System
6. Restore the complete backup from LG Backup
Does this work okay? Or, do I need to do anything else, like Wipe Data/Partition etc.? Sorry for the noob question.
Hello,
If I flash boot and bootloader, will it lock my bootloader and brick the phone if I am on LineageOS?

Backup is always good, shouldn't have to restore it as it's updating from a previous version and doesn't wipe data when upgrading. But that's the correct process with or without #6.

Shouldn't, but it would always be a good idea to backup beforehand. I would however only flash the bootloader, as the boot is the kernel and will be different than what LineageOS uses though.
I just boot into TWRP and flashed the complete zip and then flashed the latest SuperSU Zip. I pressed Reboot System after that, but, I am now stuck in a boot loop. Phone shows LG logo and reboots again and again.
I tried the Power button + Vol Down method, but, it doesn't work too. It gets to Factory reset screen, and after Yes and Yes, it goes to back to boot loop again. I am able to get into Download Mode and Fastboot Mode. Can I do something from here?
Can someone help please? Anyway to get into TWRP or recovery?
Sounds like you will need to LGUP or Uppercut your phone back to stock 20A. Then dirtycow back TWRP. Then try flashing the new ZIP again. Skip Supersu this time and try Magisk instead.
Thanks. I flashed back to 20A using LGUP and KDZ file. Need to dirtycow back TWRP now. I'm still wondering what went wrong in my process.
1. Take a complete backup using LG Backup
2. Boot into TWRP
3. Flash Complete Zip (H83020N) from TWRP
4. Flash SuperSU Zip
5. Reboot System

Do I need to reboot to TWRP once after flashing instead of Reboot System directly after flash? Any idea?
No, rebooting into TWRP wouldn't do anything. There's a script you might need to get into and delete prior to rebooting. But that only ensures that TWRP stays.
"After flashing, remount /system RW -> delete recovery-from-boot.p to guarantee TWRP sticks"
That having been said, I've done this before and STILL not had TWRP stay. Some recommend wiping /cache as well.
OR, again, use Magisk instead and don't use SuperSU.
Even if TWRP didn't stick, you should have been booting into system fine. You wouldn't be rooted, TWRP would be gone, but system shouldn't have been messed up. So something got borked, I'd have to guess, because of SuperSU.

You may have flashed the wrong stock firmware for your device, depends on your location.
If you don't want to give the (correct) stock firmware another try and flash a custom ROM instead make sure to backup everything incl. EFS and persist (very important if you want to go back to stock) in TWRP.
How to flash ArrowOS is written in the first post in it's thread:
Clean Flash
Download The ROM & GApps
Wipe: System, Data, Dalvik, Cache
Flash ROM + GApps
(+Magisk if you want root)
Reboot & Enjoy
Dirty Flash
Download the ROM
Wipe: Dalvik and Cache
Flash ROM (+Magisk if rooted previously or if want root)
Reboot & Enjoy
Downloadlinks are just below there, you have to do a clean flash.
There's no guarantee to not brick your device but if you read everything carefully, get all informations that are needed and follow the steps exactly everything should work fine. I flashed dozens of custom ROMs on several devices and didn't brick one of them.
If you never flashed a custom ROM before or haven't rooted with magisk I recommend you to read everything you can find about this procedures here on XDA before doing anything!

Actually my software status in bootloader says it is modified as I have flashed that Potter roam I have listed above.My imei and 4g is working fine.Can I do a efs and persist backup now or am I screwed?
Also if I flash arrow os(Android 9 from Android 7)will I lose my 4g and imei?
If so I don't want to do it.

You can backup persist (the most important file) by ADB using this command:
Code:
adb shell
dd if=/dev/block/mmcblk0p30 of=/sdcard/persist.img
To restore it use
Code:
adb shell
dd if=/sdcard/persist.img of=/dev/block/mmcblk0p30
Another way to backup both, EFS and persist is by TWRP, you need the latest version, 3.2.3.1:
https://eu.dl.twrp.me/potter/twrp-3.2.3-1-potter.img.html
Make a backup of all partitions and a separate one containing EFS and persist.
If you loose your IMEI and/or 4g by moving back from custom ROM to stock you can use these backups to get them back.
This problems are only related to stock Nougat, once you're on stock Oreo with working IMEI nothing should happen anymore.
When you flash a custom ROM check what you need as base, Oreo or Nougat. Some ROMs need Oreo as a base so you have to update your device in that case.
Arrow OS needs Oreo, see the first line in their OP.
