Hi guys, please is there someone who knows how to extract .Kdz file then replace the file boot.img inside it then repack it again to have a new .kdz file to be flashed using Lgup? It would be very helpful if you can help me. I would like to try it because as you know LG blocked fastboot command on nougat so i can't flash boot.img file from fastboot. Or my phone got bootloop and there is no way but blocking the 2 big cores. Thank you

No, it is not possible. Let me rephrase that. You can repack a Nougat KDZ which will be recognized by LG UP, but it won't flash. There is a signature payload in Nogat and later KDZs that is signed with an RSA cert. The public key is in lafd, the private key is locked up in LGs office. Without that SIGN payload, lafd won't flash via normal means.

Hi!
Today I downloaded a firmware(DL09C100B018CUSTC100D001) for my tablet. It is in UPDATE.APP format, not writable images.
How can I install/flash the UPDATE.APP file (the firmware) with my PC? Which software can I use?
For my Alcatel tablet, I use SP Flash Tool, but I did not find such software for Huawei tablets that use UPDATE.APP format.
I found one way, and that is to extract the images in the UPDATE.APP file using https://forum.xda-developers.com/chef-central/android/tool-python-2-3-splituapp-update-app-t3711929. Then use fastboot to flash them. I haven't tested this method yet because I haven't unlocked the bootloader yet.
Is there another option, or is this the only one?
Thanks!

Hello,
I found that it is possibility to Install new system on a phone. I did research about this but I don't really know how I don't understand everything.
When I was searching for my phone model there were some inaccuracies.
For example: I couldn't find the proper version. I have found "firmwares" that differs by one letter and I don't know I can download it or better no :/
My Phone Specifications are:
HUAWEI Y7 Prime 2018
Model: LDN-L21
LDN-L21 8.0.0.147(C432)
EMUI Version: 8.0.0
Android System Version: 8.0.0
Custom Version: CUSTC432D1
I found a site where I can download Firmwares.
My question is: Can I download for example this version and install it?
LDN-L21 London-L21A 8.0.0.150(C432CUSTC432D1)
or I must find version that exactly match my phone specifications? And what the word "London" means here?
Could somebody tell me step by step what should I do to Install new system on my phone?
Hello.
There are 1 letter difference in model - L21A and L21B. I guess there are no really HW or SW differences, but I stayed at L21B stock rom.
London is commercial codename for that type/serie of phone. LDN-L01 to L29 are similar Huawei and Honor phones with various names (Y7 2018/ Nova 2 lite / Honor 7A/7C etc). Other line/serie has other city name.
Latest stock rom for LDN-L21B is 8.0.0.151, for now.
If your phone is not rooted, still bootloader locked, with stock recovery: use System update from Settings or boot to eRecovery, connect to WiFi and let phone download latest rom and install it automatically.

I guess that you can use some of recovery modes: stock recovery, TWRP recovery or fastboot flash. Inside every ZIP is UPDATE.app. Every *.app can be unpacked with Huawei_Update_Extractor_v0.9.9.5. Eccential partitions for flash are ramdisk, kernel, product, system, vendor, version, cust. Extracted IMGs are still packed as SPARE img, so you have to unpack them with SIMG2IMG (simg2img system.img sys.img).
Now images can be flashed with custom *TWRP* recovery or fastboot (fastboot flash system system.img).

HI thank you for your reply,can u give me ldn-l21b 8.0.0.151 because I have c432
where can i find wear os for urban lg watch to flash through recovery?
I am referring to the system.img file and the boot.img
I came across this post: https://highonandroid.com/android-r...oject-treble-unlocked-bootloader-twrp-method/
and it made me look into the LG G8 and GSI capabilities and LG does run its software on top of Google GSI. To verify your phone if doubtful download this app and it will show some info: https://play.google.com/store/apps/details?id=com.kevintresuelo.treble&hl=en_US
Here is a post containing a backup of TWRP and sprint files: https://forum.xda-developers.com/t/lg-g8-twrp-and-backup-for-sprint.4247225/
I tried a TWRP 3.3.1.0 from another post and it did not work properly, I think because I have a Lineage 18.1 that was for the G8s installed and so its not installing properly, but I was able to install magisk manager and patch my boot files and root.
I tried various ways and messing up system files and so I am going to reinstall the sprint files and see what I come up with. The point is this may be a working LineageOS for the G8 thinq if anyone has TWRP installed and can install an img.xz from there. the download page shows different versions and explains that the file with bv2 is for phones with a and b slots.
Andy Yan's personal builds // GSI - Browse Files at SourceForge.net
sourceforge.net
If anyone successfully installs it please post.I didnt read carefully enough and extract the img.xz that I think becomes a system img that you can flash to the system.img with fastboot.
I'm going to try some more after I get out of this fastboot loop I am in and see if I can get it going.
