H420/H422 ROMs/Kernels/Recoveries and flash guide

[AbsolutelyProprietary]

When compiling ROMs it is advised to use H324 source because it's not so broken and is universal for single/dual sim.

How to flash?
Best method is MTK FlashTool(download)

Grab uboot (This is for devices that have android 5.0 on them, should work for all models, tested on my H420 and works)

Grab TWRP 3.0

1. Unzip Flashtool.
2. Get recovery.img and uboot.img from recovery and uboot zips.
3. Open flash-tool.exe
4. Select scatter file. which is in the same folder as flash-tool.exe

5. Select your uboot and recovery.img click on the highlighted, it will open the file picker.

6. Turn off your phone, plug in usb cable in the computer.
7. Click the download button in flashtool, plug the usb cable.
8. Wait for it to say ok.
DONE!
To enter recovery:
1. Turn phone off.
2. Hold power and volume down
3. When screen turns on, let go of the buttons and quickly hold them again.
4. A menu should appear about factory reset. Don't worry, it won't since the recovery is custom.
5. Select yes using volume keys, you'll need to do it two times.
6. Voila!

To root stock 6.0, download this and place files in flashtool like in the guide above, just pick the files and flash. (recovery.emmc.win = recovery; logo.emmc.win = logo etc.) afterwards you can go ahead and get a magisk zip and flash it (it needs to be modified to be able to patch our device, thanks to the people @ 4pda for being so helpful) here

Kicka$$ stuff.

Thanks, now that I have a working kernel source I'll make my own. Also overclocking will be very easy.

Which applications are these? I think that some applications can use only English language.

forget my last question (kinda stupid). i have a problem if you guys could help me would be great. after flashing everything succesfully on the phone, wich is a spirit H420, under phone info now i get H422. it wouldn't be a problem if only i could flash the marshmallow kdz meant for the H420, but the installation process via LGUP doesn't even start. i've seen interesting stuff on 4pda, maybe i could find H420 lollipop stock there? to start from scratch before updating?
can anyone help me to revert the phone info?

In my case, I tried to upgrade my H420 from LP to MM via lg Mobile support tool or lg pc suite, but neither does the trick, constantly getting error. I have the MM .kdz file that is named as "H42020C_00_0530" but I tried to flash it through lg flashtool 2014, this one in vain too. What I should do to get Marshmallow? Thanks!

apparently marshmallow can't be flashed using flashtool 2014, in 4pda there's a link to this video. the video is in russian, but to put it simply: go to lg site of your country, go to support, find your device, download drivers and "LG support tool" wich is a new version of the 2014 flash tool, install both of them, insert the phone turned on because the software needs to recognise the model of the phone. it will find the upgrade, "the phone may reboot, do not disconnect etc.", sadly it will go through the process of downloading the update from the internet, so no use of our kdz.
i've managed to get untill "upgrade available" step using a mobile connection, but since the firewall of my university is filtered (and beside the weight of the file, my phone would reboot, so no tethering) i can't update now. as soon as i get to a private connection i'll try. let me know if you succeed.

No way with lg support tool, it didn't pass over the download of the firmware, just give error. I resolved following (by google translate) this: http://4pda.ru/forum/index.php?showtopic=686154&st=2500#entry50284916, then the green colored link Прошивка android 6.0 с нуля через LG Flashtool, finally download the attachment named H422, about 1,1 Gb. But the guide assumes that you utilize a firmware with .dz extension, not .kdz...We need an extractor/converter, just get this http://forum.xda-developers.com/attachment.php?attachmentid=3136613&stc=1&d=1422375946.
Then, if you have, like me, downloaded the v20c MM stock firmware from a site like this: http://lg-phone-firmware.com/index.php?id_mod=190, just extract the two files needed to flash our H420: "LGUPc.dll" and "H42020c00.dz". I hope I've explained myself well or almost....:silly:
If needed, just ask. I'm pretty happy with my solution.:victory:

DONE! thanks mate! owe you one
a clarification to anyone who might come here: the 2013 version of lg flash tool, wich is required for this guide is contained in the H422.rar of the russian guide. it took me a couple of minutes to understand. also i didn't understand the part of the green link, but i managed to update anyway, so i think your advice is pretty clear.
i'm not sure if this kind of update was needed for my device (didn't try upgrade tool), but since it was succesfull for you, i already posses the .kdz and i'm on a limited connection, i decided to give it a try...and SUCCESS!
already like marshmallow, hope memory leak doesn't affect our devices, and can't wait for root!
