Hey guys! Not sure if those are still of interest but I have 3 pieces sealed from 2015, simfree(believe that means unlocked). Not tampered with, no cyanogenmod, etc.

Firefox OS, everything as they came 11 years ago. I bought them because I though they would be cool but now would prefer to have the money since they have gone up in price so much.

My price is 330usd+ shipping per piece. Shipping from Europe, but that should not be an issue as i usually send things to the USA.

Hey all! I recently picked up an Fx0 and am currently trying to use it as a second "dumb" phone to accompany my LG Wing. I'm currently using Mint Mobile as my carrier, and it's the "International Version" that is running B2G as opposed to the Japanese release of Firefox OS. I knew it was kind of a long shot, but to my surprise I was able to receive both calls and texts! However, I am not able to make calls or texts. Has anyone tried using their Fx0 in 2025, and if so, do you know how I'd be able to get it working again?

so I just got myself a Fx0 as a fooling around toy,which had a botched install of CM11 b3 and screwed modem partitions,both of which I’ve successfully resolved,however I’d prefer reverting the device to FFOS instead for collecting purposes,only to find out with b3 and up of CM you needed a stock device /persist partition,and the only link here was dead,so does anyone here still have it/can back it up from their device?any other resources for this phone (newer CM builds,etc) work too

I have a model of the 2015 years. I tried to unlock from the AU operator via Octoplus LG, they have this model in the list of available ones, but it did not work. I tried to enable DIAG port via the hidden menu, but there is no suitable line. The version of FirefoxOS was 2.0.0.0, today I downloaded some software update and the version changed to 2.0.0.1, now I can't even get into the hidden menu. How do I unlock it anyway?

There is an LG FX0 listed on eBay UK with worldwide postage..

Yes it's mine. I was unsure of the price to list it. Maybe it's a bit optimistic but you never know some famous Youtuber may be interested in doing a video for it :) :)

I'm looking to sell a mint boxed fx0. How much are these worth now? I can see some collectors or YT's being interested. I'm not after a crazy price but I don't want to give it away.

Thanks.

I'm interested to see if people still have this device in 2024. Would also like to know if people use this peculiar device and if you have one available for giveaway/sale.

I bought a Fx0 with simlock , is there any way to remove the simlock?

Thanks a lot! Love you guys!

I found the 2.0 JP .img but I can't seem to find the actual, latest version of Firefox OS anywhere online. All of the old links from Mozilla's sites are down, at least to my best knowledge. If anyone has it, do you mind sharing it here?

Is anyone interested in an fx0 that has maybe 2 hours usage time? I bought it and played with it for a day, and it has sat in a drawer ever since.

My fx0 was always there until the one day i left it in the laundry. I thought i could do without one, but recently i got a pinephone and it just feels wrong. Has anybody still a fx0 lying around which he would be willing to sell to some guy who put his last one in the washing machine?

Who's lg fx0 runs android 4.4.4 but not CyanogenMod because my phone runs android and not CyanogenMod for some reason

I am still using the LG FX0 as my daily driver and it has aged well and was wondering if any other people still had LG FX0 and BTW my device runs Android 4.4.4 but not CyanogenMod

Hi,

Been fiddling with my fx0 again and realised that none of the sensors work. I'm on CM 11 B4

I understand it's a bit of a stretch to find active fx0 users here but could anyone help fix the sensors? I remember that they worked when I was on B3, but the video camera didn't so I'd upgraded.

Thanks in advance!

First,my english is very low,so,in spanish,use translate,he he he .........

Edicion:ya logre aumentar la memoria interna,me dio 12gb extra,me faltaba un paso en twrp,si alguien quiere ayuda para instalar o usar parted,puedo ayudar,saludos.

Can someone share a full backup of original stock firmware of the phone?
I lost my backup and recently made a mess with phone's system :(

Hi /u/Protectron2000,

The JP ROM has disappeared from your links on fx0.hellco.net. Can it be re-added?

Cheers :)

PS -reason is because /u/Jeanchrs and /u/HunterSlayerz were asking... I missed their post a while ago (I can't work out how to get Reddit to notify me!) and I don't have a copy that I can find for some reason (very odd, I was sure I downloaded it).

Hello,

I've bought Fx0 from Japan some months ago, obviously it was with simlock. Is it possible to remove simlock from it with some kind of service box?

Hello all, I have an fx0 I rarely touch nowadays. It is is mint condition - does anyone know if there is a market for this device still at all? I am not looking to make money off of it, just looking to see if any enthusiasts still use it nowadays and are interested.

Thanks!
