before u upgrade to 20a u had adb drivers installed ? i dont know if u needed them with the older firmware because when i bought it it was already on 20a. My only issue and i couldnt unlock the bootloader was the drivers. after that just one click in the all in one tool , did the work.

well u r not doomed inside a developer forum. i believe as soon as someone see it , will help u.
for now try do what you can do since u have bugs , to help yourself have less bugs. root is fine. if google playstore doesnt work, then download latest gapps and extract them. manually install them in the system->app. go manually delete all dalvic-cache and cache of all apps. reboot and fixed. if u have other bug tell me maybe i have an idea to help to that too until u find a solution to the bootloader problem.

also there are replacement apps for the original 20b. maybe u cant unlock the easy way , maybe u cant install other rom, but definately u can modify the original rom the way u like it, manually. u can use alternative launcher, alternative task manager, alternative everything. modify the status bar. u can do magic if u have time to spend !!!

you didnt get what i said. u will do it manually. to have a button and do it all isnt manually -.-
i say again. fix your bugs manually ! u r rooted right ? u said that. then use a root explorer ! download latest gapps released at 21/08, open your root explorer, extract them. go to extracted ~system/app , copy / paste in your system / app the apks , navigate to data/dalvik-ache or cache/dalvik-cache delete all of those files. then go to cache or to your task manager and delete all app cache. reboot. thats it. this was fixed. the same way u can download mods or alternative apps, install them manually, delete the originals if u dont want them ( first disable them and test if the alternatives work ) , reboot. its easy. the system apps that need root access always go to system/app and the odex is created automatically after reboot.

If you want ''de-brand'' phone from OP you only need root and then you can go to file manager locate device /system /media and just delete boot operators animation.zip

this is not fully true because if you are not rooted and you don't want root, only method to restore all partitions functionality/ fix network problems after flashed stock no brand FW, and make rom fully NO BRAND is mine.

Thx in advance.

Thanks!!!

hi, if u want to debrand P8, first unlock bootloader then root the phone.
install files explorer and allow root access,
go to device /system /media and just delete boot operators animation.zip as XDADEVX say
then go to cust/ and cut folder for you'r opérator to sdcard (backup).
reboot it's done, no more brand, just huawei,
it seems thats more parameters change when deleting operator folder, like shortcut.
worked for me.

Here is a list of all the stuff that I got rid of, mostly crappy apps that are of no use and also the low battery noise and the boot sound:
*There will probably be things on the list that you use, like hangouts so check before you delete.

Problem when tried to update from CM13 20160502 to 20160506, my phone "dosnt work".

Problem when tried to update from CM13 20160502 to 20160506, my phone "dosnt work".
Hello guys,
Well, i was using CM13 for a long time without problem, but yesterday i tried to update to 06 may 2016, and when i clicked in "update" option, it restarted and the screen started to flash, i waited for about 10 minutes and it didnt changed, so i removed the batery and tried to start again, and it just loop in start screen forever, done a factory reset, and it worked, well, it was on, but a lot of problem started, i couldnt open de SD card (once i selected to use sdcard as internal, the worst choice of my life), the keyboard is not working.. i cant use my phone :/
I can start my phone, but cant access the SDCard and cant use the keyboard..
I really dont want to reflash a stock rom and TRY to root it (the last time it took me 4 days to root it, and i really dont remember how i did it, because none of the methods i found worked, just one from a russian forum worked to me using the lg stock rom 5.0.2), i'm about 2 hours searching for a pre-rooted 5.0.2 android rom for lg l90 d410hn, but cant find either :/
Can some one please save me ? I really LOVE CM rom and dont want to get back to stock rom, and i really need my phone working again :crying:
Thanks in advance!
Have a nice day.
Apparently i cant open it in download mode too.. if i press volume up + power, it just starts normally, without entering download mode :/

In the lg-phone-firmware theres 3 v20 version, v20a, v20b and v20c, wich one of them i can root with the one click root method ? Or how could i root it in the v20c version ? The last time i rooted mine with pure luck, using a russian forum (that i dont remember the name...).
If you know, or any one, i would really appreciate the help!
Thanks again my friend, if i werent soo anxious, you would have saved me hahah

Her is the link for the root(I AM NOT RESPONSIBLE IF SOMETHING HAPPENTS TO YOUR DEVICE) http://forum.xda-developers.com/lg-l90/general/root-lg-optimus-l90-44-2-5-0-2-android-t3110257

You can also root any L90 Lollipop version, including 20c, with KingRoot. Download it from XDA.

There's full 20c bootstack AFAIK, you can use any other aboot to flash TWRP then flash bootstack.

D410hn is different than D410, hn variant is dual SIM and has NFC, its bootstack may have problems with D410. I suggest that you use latest bootstack for your model.

Which TWRP did you use? Try another version, shoxxy's version may cause error 7 with some devices.
Also if you are still on an old version of KitKat you may need to flash the full bootstack to update modem partitions as well.

Your phone's system partition is empty, that's why it's stuck with LG logo. Simply copy the other (installable) TWRP zip and flash it with current TWRP and it should work. (Reboot afterwards, of course)
I have used the DatkBlue version from the same thread you linked, not sure if it will work for you. There is another version by GrinningFerret IIRIC.
There is also a workaround where you edit the ROM zip to bypass error 7, search forum.
Again, no need to revert to stock now. Good luck.

Reading your first post, it seems that you micros may be bad. Are you using another one or at least tested that one for hardware errors?

Actually the other TWRP version was built by SlimShaddy:
TWRP-3.0.2.0-w7-05-04-2016.img | by SlimShady's for Optimus L90
https://www.androidfilehost.com/?fid=24459283995313433
It's in IMG format, so I think you can't flash it directly in TWRP.

My phone is running CM13 right now, thanks man and everyone that helped

going back to stock

So, i have a P10 vtr-l29c432, bootloader unlocked, with twrp installed and from future rom installed, and now i want to go back to stock rom with Huawei recovery, to use the official updates via ota without problems. I'm not a noob but this is my first Huawei device and things are way more complicated compared with oneplus or nexus devices. My question is how to do it, because what i've so far is confusing me, if someone could explain me or give me some instructions i will appreciate it, thanks!

Hi!
same situation here. I would very much like to go back to stock but I'm not sure how... I saw a tutorial but I am not certain that that is what I need. Any confirmation would be very appreciated!!!
Tx & best

Exact same problem here on the p10 vtr-l09, seems to be a few different methods out there, either don't work or too confusing

You can try to update your phone with my guide.
This will reformat the system and your phone is on stock after a factory reset (reset is important when you come from another rom).
After factory reset you should be able to lock the bootloader.
Important is that you have in mind which Android version is installed and which phone model you have.
No warranty for this, I didn't try it or know someone with the same situation. But after learning something about how emui works it shouldn't be a problem.

did anyone tried this? I'm using custom rom from openkirin project and I would like to get back to stock. I have the stock recovery

On openkirin's website is a tutorial.
You need to extract system.img, ramdisk.img and kernel.img from update.app and flash them with Fastboot. After this boot into eRecovery and make a factory reset.

Yeah I tried to follow the instructions which they put in three separate articles, however the last one is landing on the main page and I don't see the flasing instructions. Here is the link:
https://openkirin.net/user_guide/how-to-flash-extracted-partition-images/

Doesn't work in all countries but worth a try:
Go to eRecovery (not recovery) and use wifi to go back to stock.
Worked for me.

Then do it like I wrote, the Fastboot commands should be clear if you already installed the Rom.
WiFi downloads don't work if you're rooted, you need to flash stock ramdisk manually before you can download via eRecovery.

Maybe he didn't install magisk when he was on one of the OpenKirin roms, so ramdisk is still stock. I used this eRecovery WiFi method when I was on fRomFuture, no magisk installed.

You're welcome.

Use huru updater as it is safest back to stock option for latest Huawei devices. Lookup tool right here in xda.

Jannomag here, it's possible to "update" to the same version. My script just tells the recovery to install the given update files. The recovery will overwrite the system without removing user data.
This should work without any issues but it can happen, that bugs are still present after this. If you want to fix firmware issues a complete factory reset is much more effective.

Did it help, what @glehel posted?
I want to know, because I want to provide this guide also for fixing problems like you have ... or had.

Use dload forced method with first before using scripts.
Just download the correct firmware for your device, if you know the firmware-version you had, use the exact one, because it was approved for installation:
http://pro-teammt.ru/firmware-database/?firmware_model
Extract the the update.zip and put the update.app into a folder called dload on your sdcard.
Start you phone while holding all 3 buttons, this will launch th dload process.
This way you maybe safe some time.

Is there a way to retrieve the exact name of the installed stock firmware? For my VTR-L09C432 there are multiple versions listed (like 360, 365, etc). Also I am wondering what's the difference between FullOTA-MF / OTA-MF / FullOTA-MF-PF, etc.

No, you can´t check your version, but if you choose an older firmware, you should be fine. Afterwards you can update to a newer version.
The only problem might be, if you already had oreo installed, then you should use it again for restore, because the partitionlayout changed from nougat to oreo.
All version named B1XX are Nougatfirmwares
All version named B3XX are Oreofirmwares.
Choose a FULLOTA for updates, the others are just incremental and won´t help you in your case.
To be exact you should use a FullOTA-MF-PV. The PV stands for public version and all other firmwares are just internal builds from huawei.

If you don't want to go back to stock firmware, you also have the option of custom roms such as Lineage OS or one of the others in this forum.
If you go with stock firmware, I suggest you make a Nandroid back-up before you flash TWRP. You can easily do this by booting into twrp instead of flashing (eg: fastboot boot twrp.img). After creating and copying the back-up to your PC, you can proceed with flashing twrp and never have to worry about the softbricking again =).
