H81x ROMs on H815? - G4 Q&A, Help & Troubleshooting

Now that root has been developed for all variants, and that ROM development is in full swing, can someone please answer whether an H811, H810 etc. ROM would work on an H815 device and visa versa?
Are they physically any different? I know that some of them have different LTE bands, so that might cause issues, but wondered if it was achievable?
Any answers/ help appreciated

Nope.
Usually AT&T ROMs are the ones to work on Rogers device but as a general rule, don't flash anything that doesn't say works on your variant (D852 in this case).
Just FYI for others still wondering, at the moment from what I've tested, Cloudy G3 works with the Rogers D852 model (and should on all Canadian models), and AndroidNow v1.6 (NOT v1.7, you will end up in a soft brick in fastboot mode, MAKE A NANDROID ON AN OTG USB OR EXTERNAL SD!) will flash and boot properly but in call sound does *NOT* work. I've read there are workarounds but I haven't actually read the solution (if anyone can chime in here, please do).
Other than that, Venom and Dark Wulf / Android Now 1.7 will all soft brick the device.
If anyone is still following this thread but has not seen this yet here is a link to another thread that has a list of roms that work with the D852..

[Q] Flash a LS990 with a D855 T-Mobile rom

Hi guys,
In a pickle here and need to "convert" a LS990 to a D855 for carrier compatibility. Can this be done? Hopefully without any carrier customizations...
Thanks!

You need to SIM unlock it. Look in the Sprint G3 General thread, plently of things referring to this. Hope I helped
Sent from my LG-ls990 using XDA Free mobile app
Thanks. Tried some of the sim unlock methods with varied success here in Tokyo. We only got one CDMA carrier here. Since the hardware is the same I thought I'll just flash the D855 rom and pay the $5 for the sim unlock without wrestling with it much. Would that work or would I end up with a brick?
succumbtothegreater: Are you in Tokyo? Did you manage to unlock the LS990 successfully? My attempt to flash it with a D855 rom was short lived
I'd like to know if this is possible as well, I've not been able to find out much information on if the LS990 actually has the same hardware and thus would be able to use AWS-1 bands after an unlock/flash.
Magixxx : Check my other post on how to nlocl the LS990 for any cdma network. Not sure whether it would work for gsm but maybe worth the try?

[Q] Flash D855 KDZ on the D851?

Please excuse my noob question.
Also, I realize it says this:
Q11: Can I convert one model to another (example: D852 to D855)?
NO! Do not try to do that.
Here: http://forum.xda-developers.com/lg-g3/help/help-thread-lg-g3-question-t2947298
Considering the T-Mobile G3 (D851) and the International G3 (D855) supposedly have the same chipset (Qualcomm MSM8975AC Snapdragon 801), could I theoretically flash the stock KDZ files for the D855 on the D851? Considering I'm probably going to receive no as the answer, why? Basically, what specifically are the differences that prevent the above from being successful?
Last but not least, if the above isn't possible, how could one port a STOCK rom from the D855 to the D851?

The difference in the way the bootloader works and how the system does the security checks is the reason why

You wouldnt and noone would help you because its a waste of time
I appreciate the response, however, the second part of the answer was very opinionated. I can decide for myself what a waste of time is. I'm looking for an answer that will point me in the right direction. I want to start developing custom ROMs/Kernels, but I would like to gain some knowledge about porting first.

Support for G4 - H818n

Its quite hard to identify threads for the H818N model of G4... It would be highly appreciated if someone could create a separate thread to discuss about root, custom roms etc... for each model separately...

LG G3 US990 US Cellular ROM's?

So uh, I'm, not exactly super knowledgeable on LG phones, given all my phones have been Xiaomi up to this date, but I just recently picked up a LG G3 US990 that apparently is from US Cellular. I, can't find much information on throwing a Lineage ROM on it, given that no Lineage ROM's exist for US Cellular.
What I want to ask, is if any other Lineage ROM will work for this LG G3, and if not, what ROM's would work with it that are recent.
