G6-L33
"the same as L22 and L11"
Sorry, Its the same is true, but this is for Europe and files are diferent from Colombia, thats way the issue..
It does not work in L22 and L33 , although it is the same phone with the same kernel, but the provider configuration is totally different, frequencies , network codes, etc.
I did not know because no one yet with these models had reported , I found this incompatibility shortly ...
If someone able to change or create , it may be possible to upgrade .
L11 - Europe
L22 - Venezuela
L33 - Colombia
Sorry :\
works great . thanks a lot man
i updated to B370 successfuly, everything working fine except Motion Control. when i go to "Motion Control" in Settings, there is nothing there (a blank white screen).
I remember this problem was in P6 EMUI 3 too and a patch was there to fix it. any patches for G6?
Same thing goes rong. Sensors must work! Or pictures rotate?
If not, flash b118 again, than b370. Don't forget factory reset after change cust folders names.
:good:
Excellent guide, you did a summary of four different things in one and easy to understand. For your mastery of the subject I wanted to ask your help to use my Huawei G6-U00 with firmware of China, which has unlocked WCDMA 1900 MHz band, so I can not use the phone in 3G in Venezuela.
Is there a way to unlock it?
I have tried to Engineer Mode, but it asks a code that is not known Huawei (0, 0000, 1234), . Also I tried the QPST program, but despite being recognized as a modem, do not read as a telephone and does not communicate with the RF_NV_Item_Manager.
Thanks in advance!!

Hmmm, unlock bootloader, root it and do backup from your ROM. than try b136 u251 rom, from colombia. You can use g6sknife to do backup (need root).
oemsbl version list check error!

I have Bootloader unlocked, Rooted, and CWM as Recovery.
I installed G6-U251 B136 dload in SDcard, Note ( in my U00), and gave me the following errors; oemsbl version list check error!, ?V write data error, Error; Update.app is an invalid package, Sd card update failure, SD card update abort.
I used the default recovery cause the CWM asks a zip file. and I unzipped the file and place it in the folder Dload in SDcard.
Any advice?

After you do backup with g6sknife, there is a tool you can use, is the rom extractor, is in g6skinfe to.
Extract system, cust modems.
Copy system to cmd folder, boot in fastboot (bootloader), use cmd option, than flash system if fail you need to restore your backup, because you stay with out system, if you get success, put cust and modems in backup zip and use cwm to flash it. If you get success to, you need to change cust to your provider.

G6_L11 problem after update...
Hello...
I have a G6-L11, Digitel Venezuela ...
Since I did ROM upgrade, the gyroscope and proximity sensors do not work, either lighting and ...
What can I do..??
problem with g6 rom
hi
i hope someone can help me with a little problem on my Huawei G6 smartphone.
the model is a G6-U10
but currently i have a U00 rom installed (B370, downloaded from the official Huawei site, probably the Chinese one)
installation of this rom went smooth, but this build has some serious shortcomings, so i wanted to install another rom. but that appears to be impossible!
I tried several U10, C00 and L11 roms, ranging from build B118, B193, B261,B330 and B370. most download from the official Huawei servers. and I also tried rollbacks, (U10 B360 to B136 and L11 B370 to B118), but nothing seems to work.
mostly i get the message "version list error" with some other things.
it's weird that i managed to install a U00 rom on a U10 device, but now it seems that i can't install anything from other models than U00 ánd roms that are older than the current one (B370), which is the problem, because this is the newest i think... so i can't find any other rom that i can install...
the phone is not rooted. i tried is with Vroot and Rood Genius, but it didn't work. why, i don't know. i don't even know what i precisely would do when the phone is rooted... but that's another story
I really want to install a proper working (preferably EU) rom on my G6, and at this point it doesnt matter to me how old the build is...
problem with the current rom U00 B370 is mostly this:
i can't add my Google account for the phones' contacts
play store can't install any apps
can anyone help me? cant i rollback to a better build or something?

First, if you have a U10 why you flash a U00 ROM? ...
Google G6 U10 b146, try to install it.
Tell if you made it?
G6 ROMS
There are a lot of steps to do.. Open Bootloader, Root the Phone, Install Custom Bootloader, Flash a new Rom for G6-U10.
All these Steps are full Explained in GG Development Group in Facebook.
Send a request join message, and in Pinned Post. Read , read and read. There are a lot of information and a ROM that fit your ROM. What does it mean UE in your Question? United States? Union Europa´s? the ROMS are quite different.

thank a lot!:good::good::good:
this method saved my tablet!! I almost had discarded it!!
some notes:
after installation and reboot my tablet stuck on asus logo few reboot didn't solve it. so i entered boot menu and performed a factory reset. then it passed asus logo and every things got OK except some force close messages on google services such as google play and google apps. I think update will solve them.
< waiting for device >
what should i do ?
Thanks, man
thanks a ton, yaar. your post saved my tab. I was enduring the man-made disaster (Lollipop update to FonePad7) for more than an year. Actually used it exclusively as a WiFi device due to buggy telephony software. This had been a global phenomena, still ASUS didn't care to release a downgrade option. Not even acknowledge it. I contacted their customer care and was advised to take the tab to service center!!! (what is he going to do if the company doesn't have an official downgrade option?). I was really impressed by the quality of ASUS hardware and also bought Zenfone2 for my wife.
But now i learnt my lesson: NO MORE UPDATE AND NO MORE ASUS.
Asus ME1775CG
ASUS me175cg Lollipop ww 6.3.9. In normal mode PC detects both internal and external memory. But when It boots to droid boot mode it shows "no usb cable connected" and selecting "install from sd card" option shows "unable to mount the sd card partition" How to solve this issue.

[PE-TL10] [BOOTLOADER] Alternative procedure to unlock bootloader

Hello!
For all of PE-TL10 Honor 6 Plus people, this is a procedure I tried to unlock the bootloader.
As you know, you cannot anymore ask Huawei for the unlock code. If you like me are in this condition, try this procedure.
It is the same procedure you can find here: https://forum.xda-developers.com/p8lite/general/alternative-method-unlocking-bootloader-t3799294
with just a little edit for this device. So full credits must go to @@NayeBunny. Well done mate!
CAUTION: YOU WILL LOSE ALL OF DATA. DO A BACKUP FIRST!!!!
STEP 1 - Rollback
You need to be on Lollipop 5.1.1., EMUI 3.1. I tried this procedure in firmware B332.
If you are already on Marshmallow, EMUI 4.0, then do the following:
- go to https://www.hihonor.com/my/support/phones/honor6plus/
click on the choice menu "HONOR 6 Plus Dual SIM 3GB+32GB (PE-TL10)"
You will find 2 options which are equal. Choose the second one (will return more firmwares to download)
Click on Firmware Download
Download BOTH HONOR 6+ RollBack Package Android Marshmallow to Android Lollipop and HONOR 6 Plus Firmware (PE-TL10, Android 5.1.1, EMUI 3.1, C900B332, South Pacific, Channel-Others)
You will find instructions anyway the procedure is this:
- unpack the Rollback package and extract the UPDATE.APP file into a "dload" folder which must be in the root of your INTERNAL STORAGE (I have read various posts about putting it in the sdcard*, I put this in internal storage and worked)
* maybe because it is intended /sdcard/ , anyway not the external storage.
- turn off phone
- press vol+ vol- and power togheter (you can release power button when the Honor logo appears, but keep the volume buttons pressed until you get the EMUI update screen
When it's done, unpack the UPDATE.APP of the other package and put in the dload folder of the phone (of course delete the previous one!)
Do the force update procedure as before.
STEP 2: Root
We need to be rooted.
I used Kingroot for it: https://forum.xda-developers.com/devdb/project/dl/?id=29834
You can find instruction here: https://forum.xda-developers.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461
STEP 3: the magic code
Now we are all set up, you need to activate USB Debug first (or download a ADB package as in the first link I provided).
Just go to Settings - Phone info and click repeatedly on Series Number (the second line, below model number) until you get developer options turned on.
Go back, open Developer Options and turn USB Debug on. Authorize your computer when you connect the USB cable.
Now, do this:
Code:
adb shell
Then
Code:
su -c "grep -m1 -aoE 'WVLOCK.{14}[0-9]{16}' /dev/block/mmcblk0p6 |grep -aoE '[0-9]{16}'"
(here is the difference, the code info is in mmcblk0p6 in this phone)
If all goes well it will be returned a quite long number. Copy it.
Exit the shell (typing "exit", pressing CTRL+D...) and then
Code:
adb reboot bootloader
And finally
Code:
fastboot oem unlock ****************
in place of the stars paste the number you got.
I did this procedure and I unlocked my bootloader. Let me know if it works for you!
I hope this can help people to develop good ROMs for this great device!
Sorry for the necro.. but does this method works on Honor 6A Pro for unlocking the bootloader ?

Hi,
no idea... just have a try!
As per original post, the procedure to unlock bootloader should be equal for the P8 and for other Huawei devices (like the PE-TL10): maybe just the location of the code info could be different (mmcblk0p6)
can some one provide the links for same device please?
PE-TL10 area c185​I couldn't find no where!

It seems not working links anymore!
Hmmm...
Yes, I checked and those inks are linking elsewhere. Moreover, I can't find a mirror or another place hosting these files.
Sadly, I don't own amymore this phone and I deleted all of PE-TL10 files from my computer.
The only solution would be someone who downloaded these files, when they were available, to upload them somewhere.

[ROM] [TUTORIAL] HOW TO INSTALL LINEAGEOS 16 BETA 6 NO GAPPS ON HUAWEI DEVICES

[GUIDE/TUTORIAL]
HOW TO INSTALL
LINEAGEOS 16 BETA 6 NO GAPPS
ON HUAWEI DEVICES
17th December 2020​
Authored by: RK aka Klorofill_YUM aka Purrrturbed
Tested on the following devices:
Mate 10 Lite (Kirin 659 SoC)
SPECIAL NOTE #1: To unlock the bootloader the device must be on a firmware earlier than Android 8, thus Android 7, or Android 6, Android 5 will be fine, if using the DC-Unlocker method.
Additionally, the device must be with a security patch earlier than 1 June 2018. Make sure device is supported by DC-Unlocker, check here (See link: https://www.dc-unlocker.com/supported_models_1/huawei_phones)
SPECIAL CREDIT TO USER "Chaosdave34" *see comments: Unlocking the bootloader is possible on Android 8 using the PotatoNV method.
SPECIAL NOTE #2: To install LineageOS the device must be on EMUI 8, therefore on Android 8 with an unlocked bootloader. Additionally, the device must be a supported device - please check OpenKirin’s devices list. All of this considered: in order to satisfy these 2 special requirements this may result in the need for both downgrading and upgrading firmware throughout the following steps. Also, keep in mind: TWRP and other custom recoveries are not supported! Please ensure that the device’s stock recovery installed. Please do not use TWRP or any custom recovery, the following install method will work perfectly fine with only the stock recovery installed. Make sure device is supported by OpenKirin, check here (See link: 4.https://openkirin.net/devices/)
SPECIAL NOTE #3: It is required that the device being used in is supported by both DC-Unlocker and OpenKirin, if the device does not satisfy both of those requirements, this tutorial is not for that devices. Many files that are mentioned throughout this tutorial are included in the 'Packed by RK' folder. The method is this tutorial is not officially supported by OpenKirin. The Author has no affiliation with OpenKirin or DC-Unlocker. Try at your own risk, the author does not take responsibility for bricked devices.
On the Android device: Turn on "Enable OEM unlock" & "USB Debugging" options, they are turned on from developer options.
On the PC: Install HiSuite onto a PC via plugging in the Huawei phone to a PC - This will install all of the required drivers
Backup any device data to be kept. Installing an OpenKirin ROM for the first time requires a factory reset!
On the PC: Install ADB & Fastboot using 15 seconds ADB Installer v1.4.3 (see link: https://forum.xda-developers.com/showthread.php?t=2588979) Downloads: Version 1.4.3 (see link: https://forum.xda-developers.com/attachment.php?attachmentid=4623157&d=1540039037)
On the PC: Install process for adb: Run program (Require administrator privileges), then Press Y/Yes to install ADB and Fastboot or N/No to skip, then Press Y/Yes to install ADB system-wide or N/No for current user only, then Press Y/Yes to install Drivers or N/No to skip, and finally Continue Driver installation and 15 seconds passed - finished!
Notes about adb installation: System-wide: ADB and Fastboot are installed to %SystemDrive%\adb directory, and added system-wide path. And, current user only: ADB and Fastboot are installed to %UserProfile%\adb directory, and added path for current user. CMD can use ADB and Fastboot from any directory. Drivers are installed to system - no need to install them from directories.
Now that adb is installed, to continue, the Huawei device must have its bootloader unlocked. Do not skip this step. Do not attempt to load LineageOS ROM unless the bootloader is unlocked. In the follow steps, instructions will be provided for unlocking the bootloader. Please follow the next steps carefully
SPECIAL WARNING: If the device runs Android 8 or later with latest security patch then this DC-unlock service won't work! (See “Special Note #1” mentioned earlier) - It is important downgrade and restore an earlier firmware if the device is on Android 8.
With both the Android device and PC: It is strongly recommended to use HiSuite now to downgrade the Huawei phone to its earliest firmware. Plug in the Huawei Phone, open HiSuite > Updates > Other Versions > Earlier Version > Click Restore
On the PC: Download and then install DC-Unlock from the homepage: (See link: https://www.dc-unlocker.com/), or install DC-Unlock from the Packed by RK folder (See filename: dc-unlocker2client_1.00.1431.zip)
On the Android device: Connect phone to PC via USB. Then, enable "manufacturer mode" on the phone. This is done by entering the following code into the dial pad: code *#*#2846579#*#* (SPECIAL NOTE #4: On tablets without dial pad use in-built calculator in landscape mode to dial ()()2846579()()= )
On the Android device: Now, Select "Project Menu" > "Background settings" > "USB ports settings" > "Manufacture mode".
On the PC: Launch DC-unlocker software
On the PC: Detect device by selecting Huawei phones from the manufacturers drop down menu list, "Select model" leave on Auto detect (recommended), then read the info on software for how to correctly prepare phone for detection. After phone is prepared, connected to PC and it's drivers installed, click magnifying glass button. Now, wait till program detects it
On the PC: The information the software will display now will look like something more or less similar to the example below:
DC - Unlocker 2 Client 1.00.1431
Detecting phone :
selection :
manufacturer - Huawei phones
model - Huawei HiSilicon Kirin Android phone (new)
Selected Applications port COM6
Model : Huawei HiSilicon Kirin Android phone (new)
Serial NR. : 2VN5T17A29000000
Firmware : System 5.1.0.98(08SN)
On the PC: Open Server tab, enter your username and password that you received after credits purchase. To purchase credits, this is can be done via paypal. (Buy credits here, see link: www.dc-unlocker.com/buy). Now, click "Check login" button.
SPECIAL NOTE #5: Unfortunately there is no way to do this that doesn't require paying a company - this is not a shameless plug for DC-Unlocker. The author of this tutorial does not work for nor is paid buy DC-Unlocker. The unfortunate reality is that at the moment, this paid service is the easiest and fastest method that works for unlocking the bootloader. This does not require opening the device and using the testpoint. That being said, in the opinion off the author, this DC-Unlocker service is well worth the price. For more information on getting credit, username, and password with DC-Unlocker check this source. (See link: https://www.dc-unlocker.com/how-to-get-username-password) If a username and password exists, and this method is familiar, then just add credits to the existing account and login to DC-Unlocker program clicking the "Check login" button.
On the PC: Open Unlocking tab, click “READ BOOTLOADER CODE” button. Then, wait for code to be provided. Now there is a bootloader code. This is needed for unlocking the bootloader. Save the bootloader code, this is the UNLOCK KEY.
On the Android device: Return the phone now to its original mode by exiting manufacturing mode, otherwise it might not function properly.
On the Android device: Please double check that USB debugging is enabled. Then, plug the phone into the PC.
On the Android device: A popup will appear on the phone screen asking whether to allow the PC to access the phone. Authorize the request.
On the PC: Open ADB by going to the directory where adb was installed and saved and open CMD/Terminal (Shift+Right-click > open Power Shell or Command Line).
On the PC: In the command line: type the following command, only use what is written between the " " : "adb devices"
Your devices should be listed in the adb window, if it isn't, either you didnt install the adb driver properly, or your usb port has problem
On the PC: In the command line: the following code will reboot the phone to fastboot mode, now type the following command: "adb reboot bootloader"
SPECIAL NOTE #6: There is another method to enter fastboot mode manually: Follow the next steps:
On the PC: Keep ADB command prompt open
On the Android device: disconnect it from the PC, unplug the USB, Shut down the phone, Press and hold Volume Down button and then connect the USB cable to your phone. Phone should now be in fastboot mode.
On the PC: Once the phone is booted up to the fastboot mode screen, using the adb command line, now type the following command: "fastboot oem unlock [your UNLOCK KEY here]" - Enter this command without the brackets, for example like: fastboot oem unlock 12345678901234
On the Android device: Confirmation dialog should appear on the phone screen, and give warning about unlocking the bootloader. Follow the instructions on screen, select Yes to unlock. The device will now unlock, please be aware all data on the phone will be wiped with a factory reset. Once the unlocking process is finished, the phone will boot up to the initial set up. At the start of every bootup, a warning screen mentioning unlocked bootloader will be displayed.
On the Android device: Get past the initial setup. Set everything up through the initial setup, this doesn’t have to be a complete thorough set up. It is recommended to skip all the account settings, security settings, and other settings because later steps in this tutorial will require yet another factory reset again.
On the Android device: Please update to Android 8 now. It is sufficient to update upto the first earliest Android 8 update, it is unnecessary to update to the latest update available. Now that the bootloader is unlocked, the device must be running EMUI 8.0 in order to install LineageOS 16 Beta 6 by OpenKirin - If the phone was downgraded in order to unlock the bootloader, the phone must now be upgraded via OTA in the phone's settings menu. Please update to Android 8 now - Other versions are not supported and will likely brick the device.
On the Android device: Get past the initial setup again. Once finished with the initial setup, go to phone settings and re-enable USB Debugging option in developer options
With both the Android device and PC: Plug the phone into the computer via USB, and from your adb command line, now type the following command: "adb reboot bootloader"
On the PC: Go to the OpenKirin Downloads page and download the ROM to install. OpenKirin downloads can be found here: (see link: https://openkirin.net/download/) or alternatively, find LineageOS 16 Build 6 included in the 'Packed by RK' folder.
On the PC: If the ROM downloaded is compressed (file ends with extension .xz), extract the ROM .img file from the compressed file. On Windows PC: either WinRAR or 7-Zip can be used to extract the file.
On the PC: Once .img file is uncompressed , place the .img file in the same folder as the installed adb fastboot (credit: OpenKirin)
On the Android device: Power off the device. Then enter fastboot mode. (See step 20 and special note #6 which mentions how to enter fastboot mode earlier in this tutorial)
SPECIAL NOTE #7: The fastboot mode screen must show “PHONE Unlocked” and “FRP Unlock” - Do not continue if that is not shown.
With both the Android device and PC: Once on the fastboot screen, keep the device connected to your PC
On the PC: Open a command line terminal in the same directory as adb fastboot and the copied the ROM .img file. Then, in the command window, enter the following command: “fastboot flash system <name-of-rom-image-file>.” Press enter, and see the ROM flashed.
On the PC: Once it’s completed, type the following command: “fastboot reboot”
On the Android device: Unplug the phone now - The phone may reboot quickly and launch right into the new software ROM, but it is absolutely needed to turn off the device. Turn off the the device.
Before booting up and using the ROM, it is needed to perform a factory reset in the stock recovery. Do not continue without performing a factory reset.
On the Android device: Now that the device is off, to boot into recovery, hold down Power + VolUp at the same time, and keep them held until the Huawei/Honor logo appears on your screen. If done correctly, the recovery menu will be on screen.
On the Android device: In the recovery menu, press the “Wipe data/factory reset” button.
Reboot the device and begin enjoying the ROM!

Do you have tutorial to run xposed or Edxposed?
Hello Readers!
I hope you all are well, I finally got my hands on a Mate 10 and P8 Lite 2017 for testing.
I have to say I have to regretfully inform that I have come accross an unexpected roadblock.
I can say as of now, the method described in this tutorial does not work for the Mate 10 or the P8 Lite 2017.
I got stuck at step 8:
With both the Android device and PC: It is strongly recommended to use HiSuite now to downgrade the Huawei phone to its earliest firmware. Plug in the Huawei Phone, open HiSuite > Updates > Other Versions > Earlier Version > Click Restore​When I connected both of these phone models to HiSuite I discovered it was impossible for me to roll back and downgrade the phones. The Mate 10 on the latest EMUI 10 would only roll back to Android 9.0. The P8 Lite 2017 would only roll back to and early Android 8.0 and it would fail to download Android 7, every time i tried to load, with a warning message stating the install fails due to lack space.
I can use your help: if you can verify my findings on your end by replicating the steps that i wrote in my tutorial, that can help me prove for certian these steps do not work for the Mate 10 and P8 Lite 2017. All of the steps worked perfectly fine for my Mate 10 Lite but, as it seems now, it is impossible for me to downgrade the Mate 10 and P8 Lite 2017 to Android 7 at this time, therefore the DC-Unlocker bootloader unlocking cannot be performed.

1. If the rollback option is not available with your HiSuite ("switch to the older version", "Earlier version"...), you must downgrade to the lower Oreo build version number doing the dload method (flashing Service ROM for your model and REGION (Cxxx)! This process will erase all your data! You can also try chinese HiSuite (with an .exe extension instead of _OVE).
2. You should be able to use DCUnlocker (hcu-client) on Oreo, but you may need to downgrade first ( to a firmware version before July 2018). Downgrading can be done with the dload method , using Service ROM downloaded on androidhost.ru .
I have an unlocked Bootloader but Android 8 with newest Security Patch, does the Rom also work or need I downgrade to Oreo with security patch from Juli

Hello, please do kindly share how you were able to unlock the bootloader whilst still on Android 8.
With this tool https://github.com/mashed-potatoes/PotatoNV.
I'm asking because I tried to install twrp recovery, but it hangs on startup and I don't want to brick my device.
I have now downgraded my RNE-L21 to Security Patch Juli 2018. The bootloader is unlocked and stock recovery is flashed. Is it now possible to install Custom Rom?

Yes if you have bootloader unlocker, stock recovery , and android 8, your device fits all of thr requirements to install LineageOS.
See: "It is sufficient to update upto the first earliest Android 8 update, it is unnecessary to update to the latest update available. Now that the bootloader is unlocked, the device must be running EMUI 8.0 in order to install LineageOS 16 Beta 6 by OpenKirin"
And see: SPECIAL NOTE #2: To install LineageOS the device must be on EMUI 8, therefore on Android 8 with an unlocked bootloader.

Would assume it not possible because "Additionally, the device must be with a security patch earlier than 1 June 2018."

The bootloader is unlocked and stock recovery is flashed. Is it now possible to install Custom Rom?

You have a good eye, thank you so much for catching my error!
Thanks for the help. I already had downgraded to Security Patch 1. juli 2018 and installled Custom Rom. It works without any problems.

Congrats, this serves as a testimonial that loading LineageOS 16 works, and that this tutorial is a sufficient guide.
Today I've rebooted my phone and after entering my unlockcode the screen went black and I'm back at login. Here is the logcat (I did it 3x to reproduce the Error):

Did you get it to work. I have a Mate 10 lite with android 8 and emui 8.0 with August 1 security patch. Thinking of trying potatoNV and custom rom. But I won't risk briking my phone cz i have no replacement. Can you provide with the details you weny through? And i see that when u flashes twrp u got stuck. Then how did you manage to get the custom RoM running without twrp. And how did you get it to work after getting stuck.

Easy way to unbrick a P40 Pro

Hi,
Like you can read in this thread, I've bricked my phone with Hisuite Proxy.
I've flashed:
"FirmWare" : "ELS-LGRP4-OVS 11.0.0.170"
"FirmWare" : "ELS-N29-CUST 11.0.0.3(C301)"
"FirmWare" : "ELS-N29-PRELOAD 11.0.0.3(C635R2)"
After that I had the message: "Your device has loaded a different operating system"
I tried for weeks (even with paid software, hardware test point ...) to find a way to fix it. Nothing worked. Today I've found a really easy way.
Since there's only a SD-package available for the C185-region and an installation of this would not fix the problem, since it will not flash Cust & Preload, there's a way around that.
Step 1: Download Elsa-NX9 11.0.0.169(C185) [ELS-N29_hw_meafnaf_R6] Huawei Official Firmware [Stock, dload]
Step 2: Check your region BEFORE the bricking update. In my case ELS-N29 10.1.0.182(C432E8R4P1)
Step 3: Copy the files in dload to your SD-card into /dload
Step 4: RENAME the files and folders matching your device!!!
ELS-N29_hw_meafnaf >> ELS-N29_hw_eu
update_sd_cust_ELS-N29_hw_meafnaf.zip >> update_sd_cust_ELS-N29_hw_eu.zip
update_sd_preload_ELS-N29_hw_meafnaf_R6.zip >> update_sd_preload_ELS-N29_hw_eu_R4.zip
Step 5: Put your SD-card/USB-c-drive into your phone. Press Vol+ and Power until you see the menu where you can choose "Update from SD card"
Step 6: Do it!
It will now flash the whole package and your phone works again!
However, keep in mind that your device will end up with version 11.0.0.169(C185E2).
