Your warranty is now void, don't blame me if your phone blows up blahblahblah.

Only system and kernel are being flashed, no Modem, BL, etc. You should already have updated to 20B before using.

Have not tested this myself, due to not owning the H850. edit: flashed it on T-Mobile 830 for fun with 20A 830 boot, no surprise, didn't work.

Decided to post anyway. If your going to use it, BACKUP, BACKUP, BACKUP

Based off of H85020b_00_TIM_IT_OP_1123.kdz
Only things touched are bootanimation (pixel black) and renamed recovery-from-boot.bak. It's also been zip-aligned.

Flash in recovery, profit??

SuperSu and Busybox included. Only /system is wiped, data left alone.

Should be able to dirty flash over current 20B if you like.

Any errors, etc, would most likely be related to deodexing as all files are stock.-Again, haven't tested this one myself

If anyone would like to use this as a base, Great! Would appreciate some credit. [emoji13]

Enjoy.

Optional: Adjust Screen Color

It's people like them that make Android great!

Finally, thanks to Google/LG & XDA.

...whew.

A couple questions 1. Isn't 20B just a security patch update? 2. Does this ROM zip upgrade firmware (bootloader , radio, recovery) or just update software. 3. Since it's based off of the Italian H850 variant this won't cause troubles for EU variant?

1. Not 100% sure. 2. Just system and kernel are flashed. No M/BL, etc. 3. No idea really.

Received error while flashing, code 7, seems it couldn't locate a certain filesystem and aborts installation - same here with the 20B version

Hmmm flashed ok on my h830(swapped kernel), wouldnt boot (of course, this is for 850), but still flashed. Not sure why your getting that error, already removed the assert.

If anyone wants to try this themselves here's a quick guide.

You can take the system.img and boot.img from either the kdz with LG Firmware Extractor or from autoprime complete zip.

Then Google "superR kitchen xda", if your using windows there is a VM iso in the thread you can use with VirtualBox etc.

Once you have the kitchen working just remember, set_metadata for perm, use smali/baksmali for deodexing and don't sign the zip or let it remove the meta-inf folders from apps.

Ok so I just clean flashed my 20a for h830 and got that error code 7, doesn't happen on dirty. Just restarted TWRP after wiping and then it flashed ok. Might be the same problem over here.
