2 basic questions from a beginner

Hey guys,
I have too basic questions which I'm sure you can answer me with ease. I'm kinda new to all this stuff so please don't flame me to hell. I always use XDA search and Google before asking but I just don't find clear answers to that.
So first things first.
I have a D855 16gb with t-mobile branding (germany) on firmware V10c. This seems to be the latest one for my branding. I stumped and bumped my phone recently with great success, thanks to good instructions from all you guys and devs.
Now the questions I just can't find clear answers to are the following:
Can I flash other firmwares like V10l for example, even tho my phone is branded (but bumped)?
The latest firmware for my IMEI according to LG is V10c...
The second thing I can't figure out is:
Do I need to flash a specific firmware (compatible to the custom rom) before I flash a custom Rom?
Yes I have read the instruction of many roms and almost the full thread of AndroidNow, but there are a couple of contradictory posts so I want to be very sure on that.
Maybe someone can help a beginner on those two things. I'm really trying to figure most things out on my own.
Thanks guys.

>Can I flash other firmwares like V10l for example, even tho my phone is branded (but bumped)?
There is a guide on how to properly install an OTA update (read: .KDZ and .TOT files) onto your phone. You can read the guide here:
http://forum.xda-developers.com/lg-g3/development/psa-stop-taking-ota-updates-update-t2909412
>Do I need to flash a specific firmware (compatible to the custom rom) before I flash a custom Rom?
As far as I know the kernel is the only important thing you have to really keep an eye out from. It is very important to flash the correct kernel for your phone model. Other things like whether it is an 16GB or 32GB model, provider etc.. is not clear to me if that is important too.
I think it's best to just follow the threads here on XDA and wait until there are going to be releases of major ROMs and more information about these subjects.

In short, no and no. If the latest firmware for your branding is 10c, do not flash any updates for another model number.
http://forum.xda-developers.com/lg-g3/development/psa-stop-taking-ota-updates-update-t2909412
That Guide will show you how to take the kdz or tot file, when an official one for your model number is available, and safely flash it without losing TWRP. As the title of that guide warns, never take an OTA update while Bump'd and never flash a stock kdz or tot file. You must follow that guide exactly to create a safe zip file to flash.
As for your second question, in the original Bump thread it states that this is not like Loki and that you do not need to be on any specific firmware to flash a custom rom as the kernel will come pre-Bump'd and require nothing from the end user.
Hope that answers your questions, feel free to ask more here anytime. And thank you so much for putting this in the proper thread and having legitimate questions that are well justified. I know there is a lot of talk about the Bump method, mostly trolls, but just know that this phone is far more "unlocked" than the majority of others.

Thanks to both of you.
I already blocked OTA`s properly. Its just very confusing because of the "suffix" of the firmware like "A6MD". I wasnt sure if that has to match up, since its unlocked.

I wouldn't recommend you to manually download firmware by yourself especially if you are begginner as you said you are. You could brick your phone if one tiny thing is done wrong. But you can try updating it using LG PC Suite. I got my International model 2 months ago and it was on basic firmware version v10a. Trying to update firmware with the phone itself just showed me message that latest firmware is installed. After that I installed LG PC Suite from LG's website if I remember correctly and installed it. I just plugged my phone to pc and ran LG PC Suite and then it said that I can update my firmware version to v10l.
So I recommend you to try with LG PC Suite first, I think its your safest bet to get correct latest firmware for your G3 variant.

But this method seems pretty so simular to generic OTA and would probably screw up my custom recovery and/or root access? Or am I getting something wrong here?

Device variant/ROM question

Hello,
I have an LG G3 AS990 (Ntelos). I would like to root and flash a different ROM, but am having trouble finding my variant as Ntelos is a smaller carrier. Does anyone have any advice on compatibility between any other variants? Any advice would be greatly appreciated.
Thank you

I've continued to search, but haven't found anything. Just hoping someone may have some information.

I've been researching this as well. You could try finding the beta version of CM for Sprint's LS990. I would try it just for the fun of it, but I'm nervous that I don't have the stock rom for AS990 to revert back to. I have my system backed up, but I'm not comfortable enough to rely on that to save my phone if I brick it trying to install CM.

Bump. I have the same problem here, except that mine got pushed an OTA patch that prevents stump and others. So far no firmware I have found is compatible with this device to even downgrade in order to root in the first place. If anyone has succeeded with as990 NTelos please help.

Bumping the necro in hopes of support. XD my software says as99020a but the writing on the back under the cover says us990... So I'm not sure what I'm supposed to do especially since I can't even find a place to download the firmware for manual updates.. Etc. :-[ Damn ntelos

AS990 Recovery?
Has anyone found a recovery that works with the AS990?

I have an option
I've posted a way to use TWRP and ROMs for the LS990 on the LG G3 subreddit, I need 10 helpful posts before I can post it here because I have a few xda posts and downloads linked.

AS990 experience
Hi all,
I have tried different roms on my as990 (Carolina West Wireless) by using the method on reddit (HERE) and everything works just a few things to keep in mind
To get your sim to work on a custom rom you may need to change the build.prop ro.build.target_operator=, and ro.afwdata.LGfeatureset=
Take note of these settings before you try to reflash the phone. If you change one, change both if applicable.
Remember to backup your old build.prop
Backup all apns before you start using method found (HERE)
Backup build.prop
Oh and did I mention backup build.prop
The restore files can be found (HERE) and use the guide found (HERE) replacing the files mentioned with the ones in the post. If you use this method to restore you phone, the build.prop from the reddit post will not work so use the old build.prop that I'm sure by now you have backed up or you will have to get the custom .dll file elsewhere to restore.
For all who have taken the ota update, the restore method works for that too
Your carrier files are automatically restored if you use the firmware in the above post. That is to say they were for me but if anyone else test this
no guarantees but it did work flawlessly for me.
Also I am currently working on a recovery for AS990 if anyone has any ideas feel free to chime in
A couple of side notes
The method by tybskinner may also work if you flash to US990 as well, but I have not tried this yet. To do so you would need the custom .dll or the build.prop for US990
Users have reported that SIM unlock is possible by changing the the build.prop ro.build.target_operator= to global or open however I have not tried this yet
If anyone has a method to change the PRL on the device please let me know I have tried several options but no method I have tried will allow the PRL to stick
P.S. not trying to steal your thunder tybskinner just making it easier for people to find the links

Thanks for the info guys. At this point I'm having issues just trying to root the thing. Lost root with Lollipop, and for some reason I cant seem to regain it. Oh well. The price you often pay for having a smaller carrier (I actually work for nTelos, so its my work provided device).
Thanks again. I hope you guys are able to get yours setup the way you like. :good:

Currently there is no root method for the AS990 device on the newest ROM however if you follow the guide posted you can downgrade to the previous version and go from there.

Have a look here...I found a way around the whole super secure as990 crap

[Q] Downgrade LG G3 to stock kitkat

hello there folks
I just ordered the LG G3 online and it'll arrive somewhere next week. Ive bought this device most beceause of the easy rotting and TWRP method (just install Stump, use it to root and then flash a TWRP .img with flashify)
But this company (Its called Mediamarkt, Europian people will probably know it) seems to feel the need to upgrade their devices themself, so Im afraid Itll probably already have Lollipop on it when it gets delivered. If this happens to be the case, how can I flash back the 4.4.2 stock rom?? I know you have to use KDZ, but I aint very good at it so thats why Im asking you guys. Its the Europian 32gb D855 model. a reply that includes the link to the right KDZ file and proper instruction would be awesome!
(dont refer me to other posts as ive already seen all of them, otherwise I wouldnt make this thread)
Thnx in advantage

dont update or do anything unless you consider yourself strong minded and comfortable with rooting, flashing etc
the phone tends to get locked the moment you try to update.
So think thrice before doing anything with this phone.

Thank You for your reply, I've searched for long, and I want to update it, as long as a good guide is presented, I think it'sfine to use root and flash.

For persons that have done it (root, custom recovery, custom ROMs) it IS OK, but for people that have little to no experience doing it, reading and absorbing info thru video media is invaluable. This device can be a little balky, so heed the warnings given, STUDY UP, and be careful...

Thank you for the reply and advice, I actually did a lot of reading, and concluded that I need to return it to stock firmware, update it then flash it to read my sim card, I just do not know how to revert to stock firmawre and flash the sim card.
Any Ideas ?
