I update to B132 and I have some bug on this firmware
https://www.youtube.com/watch?v=1yVya1LV5IM
https://www.youtube.com/watch?v=-Mhg3hdcSq0
I want to dowgrade from nem-l21_c432b132 back to stock nem-l21_c432b100
I copy the dload and update.app B100 + *#*#2846579#*#* and press update, but is not working, i get update failed.
How can downgrade the firmware?

You got the update fail cause your version is higher than b100.
I think that if you want to downgrade you will have to download Full B100 not the OTA.
But I recommend if you want to do this use the b130 - I am using it and it is very good.
Do the whole procedurę through turned of phone: then VOL down and up together if I remember correctly.

I have try Full B100 not ota.
Not working.
Maybe some one know how to downgrade with fastboot?
nem-l21_c432b132 to nem-l21_c432b130 is working downgrade.
But i want nem-l21_c432b100

i try flashboot
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
At fastboot flash system system.img i get failed
someone can help me?

@zzhunt This is an experimental method to go back to B100 by using OEMinfo. You do on your own risk! Required unlocked bootloader and installed TWRP (from Meticulus). Before performing make a full backup in TWRP.
1. Download here this package and put together of firmware B100 on the memory card,
2. Run and install in TWRP this package.
3. When finished install it, restart your smartphone to fastboot mode (Reboot>Bootloader)
4. Plug it into your computer and flash original recovery [LINK] a command "fastboot flash recovery recovery.img"
5. When you can flashed, then disconnect and hold power switch. When the informations will disappear from the display, immediately press the buttons Volume up and Volume down,
6. Will start the flashing system and after finishing restart your smartphone
7. Done!
I tested so far only on my device and don't know, what will happen with smartphone a different serial number/IMEI etc., but rather it should go.

Reverting back can be done by putting the full update in dload folder in sdcard. I have once got that error that u r talking about after the installing process completed. So i simply rebooted. And i got the stock one. So try this, just reboot and see.

In full stock firmware, after extracting it, there is dload folder. In dload folder there will be 2 folders and update app.

I try B100 firmware bulgaria and greece
On greece is only dload folder and update.app
And in bulgaria is 1 folder hw + update.app
http://postimg.org/image/w6e41dxet/
in hw folder is other folder EU and inside is update_data_hw_eu.app
I try with update.app + this folder.
Not working, at 5% fail install and start normal.

I want to go back to B100 because this updates B130-131-132 is junk for me.
Only problems i have

You have unlocked bootloader? If not, you'll have to unlock - here is a tutorial on how to do it. Then you flash TWRP and perform what I wrote previously.

for me b132 optimized alot battery life and ram usage. also gpu works better.

I've tried this,albeit without the userdata.img however although it took me back to EMUI 3.1 and Lollipop some menu items were not working such as setting a screen lock and unable to get to guest mode.
Would also not update using the B114 full ROM, would only accept the B303 beta.

The path is c:\.....where you extracted........ and the update.app must be a full rom not ota update

Ive tried flashing the recovery.img, boot.img, cust.img and system.img from B145, then factory reset and then restoring a TRWP backup of B114 however it still doesn't work, still cannot access lock screen settings (and fingerprint settings) or security settings.

If you are both talking about flashing those files whilst on B303 or B321 it's just not possible at the moment..you'll need to restore a TWRP backup u made whilst on MM Beta to get security options back.
You just can't get back to 5.1.1 from MM Beta at the moment

Okay so ive tried to manually update. Won't work. Should i try to flash the images of b321 mabye?
Basicly stupid me doesn't have backup :/
Sent from my HUAWEI CRR-L09 using XDA-Developers mobile app

The same happened to me - semi-bricked my phone whilst I was on b321; wanted to root it and it didn't work. Now I'm back on b145 because I have no TWRP backup of b321 (stupid me). So, could anyone make a (clean) TWRP backup of CRR-L09C432B321? That would be awesome!
Thanks in advance - fbs

Thanks for the input, but I guess this is not my problem. I'm able to flash via fastboot and my FRP is unlocked.
I tried flashing the files from all versions - b145, b303 and b321 (eg. system.img, recovery.img, cush.img and such), but I couldn't get b303 or b321 working again. I end everytime in a boot loop.
Maybe I did something wrong, but that's the reason I restored an old b145 twrp backup.

Have you tried factory reset then putting a full version of B145 in the /dload/ folder and doing a update through the settings..update..local update

Yes..after you have flashed the file via fastboot write command fastboot reboot..put the full firmware in the folder of dload of internal sd card....press with usb connect of your pc volume up + power and enter in huawei erecovery..press shutdown....disconnect usb...press volume +,volume- and power and release only power after huawei logo..you enter in the upgrade firmware...if flashing block at 90℅ for several minute flashing not is correct..and you need this tool huaweiphonewriterv4 with usb connect to pc for flashing full firmware without error...you have need after flashing via fastboot recovery and boot the wipe data factory reset...try before with wipe data e factory reset in the recovery ..enter in this mode without usb press volume up + power..

Check control in device manager of pc..in fastboot mode you have displayed in the samsung android interface driver driver name ADB BOOTLOADER INTERFACE..IS CORRECT DRIVER..in recovery you have driver ANDROID ADB INTERFACE...check the driver correct..is very important for this...not is displayed ANDROID SOONER SINGLE ANDROID INTERFACE..not work correct this driver...check you.

I tried that, yes. But with no luck; through the settings I can't make a factory reset (it fails after a few seconds), same with the stock recovery. I haven't tried it with TWRP yet, maybe this will work.
And also the method with the dload folder fails - no matter if I do it via the phones settings or when I boot directly into the setup with volume-down and volume-up (where it stops at 90%).
Maybe a full version of b303 or b321 would work, but for now we don't have that yet.

I guess that's somehow the case - As mentioned above, I already tried to upgrade the firmware with volume-up and volume-down, but it stops at 90%. But I will try it again in the order you said, thanks!
My drivers are all fine, working with them for a while now with a lot of phones and never had problems using fastboot or adb commands (I'm using the ones of the android-sdk) - but you're right, in fastboot it is called "Android Sooner Single ADB Interface". In stock recovery my phone isn't displayed in the device manager of my computer. When I boot up normally with USB-Debugging enabled it is called "Android Adapter ADB Interface".
Honestly I'm a bit concerned about using the said software "huaweiphonewriterv4" - it doesn't seem very
reliable to me

With tool of dcunlocker i have save my device...android sooner single adb interface is not correct driver in fastboot mode...right key mouse in the pc driver device manager,update driver,manually search and toggle compatible driver..list of driver is down of samsung driver..driver correct is adb bootloader interface version with data driver..most recent..accept message of windows driver is not compatible version..install driver..are his the driver correct!!100℅ work...your problem is twrp ..you not have flash right recovery stock..twrp already installed on your device..you must cancel twrp with recovery stock..

Ok, I'll try a driver update, thanks
The thing with the recovery - right now I'm on the b145 recovery, but I've tried the b303 and the b321 recovery as well as the TWRP recovery. I just switched between each versions. But I will try the steps you provided, thank you very much!
It's just that I can't make a proper factory reset - it fails after a few seconds, but my phone is then reset. I will try it again with the files (everything I'm able to flash) of the last working firmware - in my case it was b321 before I ****ed up. Again, thanks

You have to access the update menu without a USB cable connected to update via Update file in dload. If you Reboot into Update Mode with a cable connected, your device will go into USB flashmode und will stop at 90%.
Keep pressing vol up + vol down + Power without a cable connected and Release the power button after the Vibration.

If you do it this way, make sure there is no USB Logo in the circle.

yes..is correct..but if you had a b321 before crash you need to download full 321 and extract boot and recovery of 321 with huaweiexctrator tool and flash it in fast boot mode..then upgrade full firmware in recovery..

I have the same issue, i have mate s with tim brand, i change my brand to no brand, i have installed the firmware b114 (first b110) nex b145, and i try to instal mm beta, but installation fail, i try to flash b145 and fingerprint doesn't work. Next i contacted dc forum with live chat, they help me to return at b114, when finished the finger print It has worked well for 15 min and then gave me problems again.
They told me that They do not yet have a solution for people that have upgrate the mate to MM, and must be wait for the official firmware MM for solve that because the beta of MM is not full version

Guys, I did it
I just found a bigger OTA update which allows you to upgrade directly from b145 to b321.
b145 to b321 OTA
I loaded the recovery.img and boot.img of b145 via fastboot on the phone, after that I just put the downloaded zip on my external sd-card in the dload folder, made the update via settings and et voilà, done!
Just quick tested a few things, but everything seems to work.

TWRP supports Data Transfer from PC to your phone. Just plug your phone to PC and then you should see your phone. If it won't work, use ADB Sideload. Download ROM to your PC to adb folder, then enter to sideload in TWRP and use command adb sideload [your_rom_name].zip
This should work

Pls help me how.

What version of the phone do you have? EVA-L19C*** ?
Post back and I'll try to help you! Is not all lost.

Yes its EVA-L19. i was running nougat.
1. I unlocked bootloader
2. And rooted with srktools but it was for marshmallow.
3. I wanted to unroot and relock bootloader.
4. I wiped everything. it said "No OS"
5. Now im sad.

What region? EVA-L19C***. The three characters after the C tells you the region the phone was built for. It could be C432, C185 etc.
I need to know that.

If you own an European P9:
1. download EVA-L19C432B386 firmware
2. Extract the UPDATE.APP from the update.zip file and copy it in a folder C:\temp for convenience.
3. Using Huawei Update Extractor unpack UPDATE.APP to a subfolder. You should obtain several img files and some other files which are not needed.
3. Download Adb Toolkit from somewhere. Copy SYSTEM.IMG, BOOT.IMG, RECOVERY.IMG, RECOVERY2.IMG files to the "Adb Toolkit" folder.
4. Open a command prompt session with administrator rights
5. From Adb Toolkit folder run in sequence:
fastboot flash boot.img
fastboot flash recovery recovery.img
fastboot flash recovery2 recovery2.img
fastboot flash system system.img
6. Reboot the phone!
Does it boot normally?
6.a. It does not boot. Doesn't matter. Proceed to the next step!
7. Obtain the rollback package for your phone, L09 or L19.
http://download-c1.huawei.com/download/downloadCenter?downloadId=92086 - for L09
http://download-c1.huawei.com/download/downloadCenter?downloadId=92093 - for L19
Extract update.zip file, copy UPDATE.APP to the SD card in the "dload" FOLDER. Nothing else should exist in this folder.
Force firmware update by rebooting your phone using the three key COMBO (VOL DOWN + VOL UP + POWER) buttons. When you see the Huawei logo, release the power button, holding volume up and volume down until you see the update process beginning, something like a circle with % nr.
8. Download L19C432B182
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v74994/f1/full/update.zip
or L09C432B182 firmware,
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v63880/f1/full/update.zip
depending on the phone you have.
Extract update.zip file, copy once more UPDATE.APP to the SD card in the "dload" folder, overwriting the existing UPDATE.APP file.
Force firmware update by rebooting your phone using the three key COMBO (VOL DOWN + VOL UP + POWER) buttons. When you see the Huawei logo, release the power button, holding volume up and volume down until you see the update process beginning, something like a circle with % nr.
Important that you should download the equivalent firmware for your phone.
The rollback package works for both versions of the phone L09 (single sim) and L19 (dual sim) so it's not really important which one you use. You will flash Marshmallow 6.0 anyway (EVA-L19C432B182) over by force update.
You will eventually boot into Marshmallow 6.0 - L19C432B182 firmware. Run system update 3 times to reach Nougat 7.0. It will update the firmware to Nougat 7.0 - EVA - L19C432B386.
Please leave feedback and click the thanks button!

I have the same issue.

TG, I don't need to unbrick but I wonder, if it would boot correctly to c432b386 in step 6, would it be necessary to continue with rollback and OTA upgrades to reach again the same c432b386?
Also does such extracting and flashing of partitions manually work for every FullOTA-MF-PV?

I always follow by flashing the base B182 firmware and update it via system update to have a clean running android OS.
A thanks would be nice in the forums.

I'd say proceed in flashing L19C432182 to erase old partition table and obtain a clean OS installation. I always do this, regardless if it boots after step 6 or not. Sometimes it won't boot at all.
I don't know if that applies to all firmware. For EVA-L19, I've noticed after numerous flashes, that B386 brings the partition layout to a usable state so I can force flash using the dload method.
It took me a while to realize that B386 is the right firmware for fastboot flashing. Other firmwares fail completely when flashing system.img.
Using the above described method gave me 100% results.
I always do a factory reset and wipe cache/dalvik cache afterwards.

If you own an European P9:
1. download EVA-L19C432B386 firmware
2. Extract the UPDATE.APP from the update.zip file and copy it in a folder C:\temp for convenience.
3. Using Huawei Update Extractor unpack UPDATE.APP to a subfolder. You should obtain several img files and some other files which are not needed.
3. Download Adb Toolkit from somewhere. Copy SYSTEM.IMG, BOOT.IMG, RECOVERY.IMG, RECOVERY2.IMG files to the "Adb Toolkit" folder.
4. Open a command prompt session with administrator rights
5. From Adb Toolkit folder run in sequence:
fastboot flash boot.img
fastboot flash recovery recovery.img
fastboot flash recovery2 recovery2.img
fastboot flash system system.img
6. Reboot the phone!
Does it boot normally?
6.a. It does not boot. Doesn't matter. Proceed to the next step!
7. Obtain the rollback package for your phone, L09 or L19. The L09 and L19 work for both versions interchangeably.
http://download-c1.huawei.com/download/downloadCenter?downloadId=92086
Extract update.zip file, copy UPDATE.APP to the SD card in the "dload" FOLDER. Nothing else should exist in this folder.
Force firmware update by rebooting your phone using the three key COMBO (VOL DOWN + VOL UP + POWER) buttons. When you see the Huawei logo, release the power button, holding volume up and volume down until you see the update process beginning, something like a circle with % nr.
8. Download L19C432B182
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v74994/f1/full/update.zip
or L09C432B182 firmware,
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v63880/f1/full/update.zip
depending on the phone you have.
Extract update.zip file, copy once more UPDATE.APP to the SD card in the "dload" folder, overwriting the existing UPDATE.APP file.
Force firmware update by rebooting your phone using the three key COMBO (VOL DOWN + VOL UP + POWER) buttons. When you see the Huawei logo, release the power button, holding volume up and volume down until you see the update process beginning, something like a circle with % nr.
Important that you should download the equivalent firmware for your phone.
The rollback package works for both versions of the phone L09 (single sim) and L19 (dual sim) so it's not really important which one you use. You will flash Marshmallow 6.0 anyway (EVA-L19C432B182) over by force update.
You will eventually boot into Marshmallow 6.0 - L19C432B182 firmware. Run system update 3 times to reach Nougat 7.0. It will update the firmware to Nougat 7.0 - EVA - L19C432B386.

L19C636 is the base firmware for asia pacific.
Please confirm that!

Dude, I am trying to help you.
Post your base firmware number!
Which one is it?
L19C636 ???
What was your last firmware that you had installed on your phone? L19C636XXXX ???

@Gian_123
Flash EVA-L19C636B190 OTA-MF firmware (http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1079/g104/v64610/f1/full/update.zip) instead of EVA-L19C432182 at step 8.
You should be able to receive the next Nougat 7.0 update and further updates.
Post back and let us know how it went!

Never flash anything on your phone before unlocking the bootloader!!! Never!
Try to obtain the data in the screenshot, from your phone box or from huawei call center/service and unlock the bootloader!
Go to en.ui.vmall.com/plugin.php?id=unlock and enter that information!

Thanks brother for your revert.
Today Morning i submitted Cell to Service Center for sort out this issue.
i would like share you , how i stuck in this loop
i was just doing rollback procedure from 4.1.2 to 4.1.1 due to some OTA updates issue in Cell.
i followed Huawei official dload method for this work. After successfully install intermediate package mobile reboot and remain in boot-loop even i tried number of thing to install recovery, hisuit, adb but nothing has to be worked and than finally i decided to go service center. now m waiting from service center answer..

recovery.img for P9 Plus

Any chance have the original stock ROM VIE-L29C636B130 in their archive? Huawei had removed that already.. and I am stuck in updating my phone as I didn't have a backup of the original rom's recovery file..
Huawei OTA does not pick up any updates and tools I have tried so far failed to apply the full OTA.

restore recovery from recovery2 :
go into twrp
advance -> file manager -> /dev/block/platform/hi_mci.0/by-name/
copy recovery2 to SDcard (or other place)
rename copied recovery2 to recovery
recopy the file to /dev/block/platform/hi_mci.0/by-name/

And after that just reboot? Apologise for the question but I am new in that and I wand to restore my stock rom, recovery, lock the bootloader. For warranty claim purpose ...
Also if anybody has an archive with the firmware file which should be copied to sd and card flashed to my phone ... VIE-L29C185B360
Any help will be highly appreciated.

yes just reboot and the stock recovery must be come back
now to unlock the bootloader you need to install the B181 (download here) but if your current version is B360 you need to rollback to B300 (download here) first then to B181
steps
1- extract "update.app" from the B300 zip to dload folder in SDcard and install it with the 3 buttons methode
2- extract "update.app" from the B181 zip to dload folder in SDcard and install it with the 3 buttons methode
normaly the bootloader must be locked after installation but some factory apps have deleted
to recover this apps you need to unlock your bootloader and flash twrp to recovery2 not recovery (fastboot flash recovery2 twrp.img) then install this zip via twrp, then re-install B181 again
normaly your phone must be in his factory stat
(sorry for bad english)

Many thanks for your help.
My bootloader is already unlocked, on the second paragraph you wanted to say "to lock the bootloader". I am correct?
I will do this as soon as possible and will come back with updates about the status.
A lot of steps, I hope it will go smooth enough for a begginer like me ...

No , after the installation of B181 (step 2)the bootloader will be locked, you need to unlock it again to flash twrp and installa the apps zip then re-install B181 to relock the bootloader (locked stat)

Well, it seems that I am out of luck, when I have arrived at home, the links provided by you I think just stopped working (it was impossible to download the files from work) and I cannot find the files that you are talking about.
Firmware finder is giving me only the files as below. Any chance that at least VIE-L29C185B181 to be the right one? I have attached the picture below.
Corrected: Only the last from your links is working, a 329 Mb file.

all links work for me
you find the files here
http://consumer.huawei.com/eg-en/support/phones/p9-plus/
download :
-P9 Plus Rollback Package (VIE-L29, from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1, C185B300, MiddleEast&Africa)
-P9 Plus Firmware (VIE-L29, Android6.0, EMUI4.1.1, C185B181, MiddleEast&Africa)

Hi, thank you for your patience.
It happened something strange last night, when I have tried to download the files I was redirected to a page where it told me that the connection was refused by server. This happened every time when I tried.
In the morning, magically, the links were valid and everything worked as you said. I do not have a proper explanation about what it happened.
Now, for reasons that I do not know, the download speed is very low, approx. 80kb/s which will give me more than 1 day to download the files (at least the biggest one).
I already started downloading, hopefully all will be ok.
I will keep you informed.
Again, many thanks for your help.

Wait. VIE-L29C636 only have VIE-L29C636B180 not VIE-L29C636B181.

what is your current version?

Vie-l29c185b360

here is the recovery.img from B360 package : Mega
flash it to recovery and recovery2

Thanks.
I have tried to flash it but I have the error:
error: cannot open 'recovery.img'
The file is in the same directory with fastboot and the command is:
fastboot flash recovery recovery.img
---------- Post added at 07:50 PM ---------- Previous post was at 07:19 PM ----------
My mistake, apologise for this. The file was in the same folder, but I was typing the command in another folder.
Now for recovery2 what is the command? I cannot find it anywhere.
fastboot flash recovery2 recovery.img?
---------- Post added at 07:54 PM ---------- Previous post was at 07:50 PM ----------
Another question. In recovery2 shouldn't be the eRecovery?
I am asking this because maybe the guys from customer support/service will check this stuff...

fastboot flash recovery2 recovery.img, yes this is the command
recovery = recovery2 but they boot differently (recovery boot as reset factory or updater , recovery2 boot as eRecovery)

@lockmunk: I do not know how to do it, even for using fastboot and adb commands I have done a lot of research on the web.
@finally, I have flashed recovery.img that you gave me and also checked the phone:
- Volume up + power button pressed -> stock recovery
Now I will try the next step ...

Just another question, how can I boot in recovery2?

[TIPS] Revert Custom Rom to Official and untouched - Hard restore

Hi!
I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.
After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.
1. You ave access on TWRP?
-If not, pleas unlock your bootloader (again) and flash TWRP recovery for you actual version (marshmallow or nougat).
-perform a full wipe and restore your partitions on "ext4" format, shutdown phone.
2. Get a "oem_info.zip" for your model phone (dont extract the .zip) and push it on your internal or external sd.
-This archive contain cust and oem info for patched your phone at the correct manufacture information.
-I have a link for VNS-L31 (c432, but is not very important) HERE LINK
-If you have other model (VNS-L31) pleas find a correct patch for you (VNS-L21, ...).
3. Find and download a EMUI marshmallow official full-ota update.
-for a VNS-L31 i advice choice a VNS-L31C432B160 full-ota update.
4. Unpack your update archive.
5. Create "dload" folder on your internal or external sd and put it UPDATE.APP
6. Reboot phone on TWRP recovery and flash "oem_info.zip"
7. Use dload methode for update (hold 3 buttons phone and dont release before "dload screen" appears)
8. Unlock your bootloader again (important!) And make a factory reset
9. Your phone reboot (please wait ) and done!
Ok now you are on official version, please update on setting menu >> update and choice, rest on official or flash a custom rom..
P9 lite brick precision:
In my personal experience the "p9 lite" is very easy to flash, mod or other tips and the risk of HARD brick is very very tiny.
If you see this page and your phone bootloop, relax, keep calm at 99,999% you have a little and ridiculous brick
Good luck and flash happy!

I can do everything up to point 6... won't enter to twrp... stays on Your device is now booting...
Update: I can now reach point 7 but now won't do dload (3 buttons) method... Huawei logo all the time. Can't even turn off the phone

In my other thread you post the same problem but is not entirely the same..
You succeeded to enter on fastboot mode? Flash recovery?
If you follow the steps 1-5 is impossible to fail the 6 point..
You have acces on fastboot mode or not?..

I did update the post... 3 hours ago I wasn't able to enter TWRP, some way I did managed, now I can enter fastboot, I did flash custOEM (sorry I don't remember exactly the name but it's the one of your post) .zip file. Now I can't do dload method, stuck on huawei logo. If I try to go to recovery, I got red message "phone fail validation"...
I know, I post on both but I was trying to do everything...
just tried... validation red error message won't let me go to TWRP now...

You have a VNS-L31C432?
Your phone does not enter at dload mode?
Wipe all partitions an retry flash a oeminfo for your model phone (if not C432 you need right oeminfo).

How can I wipe all partitions if stuck in Huawei logo? Is there a way to do everything from adb command line? (I'm using Mac and cannot use all the tools I've found here XDA neither hiSuite which is basically a backup photo/video only the Mac version).
Thank for helping, really appreciate
To answer your question in the other thread, yes bootloader is unlocked and I am on C432.

What's your rom have before the bootloop?
You have the right version of TWRP for your rom?
If you have a MM version Don't flash a TWRP for N.
Send me a link to TWRP version used (thread forum)

Before the bootloop I was on L31C900 (on the phone) but I did actually flashed C432B160 because I did rollback. TWRP used I've found in the other post where there's a OEMfile to flash (but for this I need to double check because I did look so many pages which I am not 100% sure.

I not have experience on other model that C435.
But i suggest to find a oeminfo for your variant (C900?)
For TWRP you need flash a version for MarshMallow HERE
Flash it and pas return here (fastboot flash return and first enter to new recovery)

Hi, found Windows emulator for MacOs so I extract from update.app boot.img and flash.
I did format all partitions as told using a proper twrp this time.
What's next step, system says NO OS INSTALLED?

Flash partitions on .img files is not needed.
Just find a corect oeminfo for your model phone.
Flash it on TWRP recovery.
Use dload methode to update on basical version (MarshMallow b160).
After that, unlock bootloader again and make a factory reset.
Switch on your phone (the first boot make long time).
Update on last emui on OTA.
Done!
After that you able to install a custom rom.

Thanks again you're saving my life!
IT won't turn off so been always on it won't keep the charge... Writing so because apparently it won't go to download mode (dload) if plugged in. On the other way if I unplugged from power it won't even start. Shall I force to download mode using console ADB or FASTBOOT? I had looked but can't find anything...

You not able to switch on your phone without connected charger?

Correct. Because I'm not able to switch it off it won't keep the charge. When discharged, the minute I do plug on charge it wakes up... That's the loop...
My main question is: does a command exist to enter download mode using terminal?

You have a hardware bug?
No abd command to enter dload mode..
Try flash a update.zip with twrp (not guaranted)
After that unlock bootloader again and make factory reset.

Hi, I followed this guide to go back to stock from elite rom. I flashed my oeminfo.img on twrp and then went to dload combination. Do I have to unlock the bootloader after the reboot? Thanks!

Hi,
I followed your guide and it works perfectly thanks!
