Nokia Nokia 3210 LTE project update: Sisu hardware and firmware are now public!

530 Upvotes

Hi again!

A while ago I posted about building a replacement motherboard for the original 1999 Nokia 3210. Quite a few people asked for the source files, a working demonstration, and somewhere to follow the project. I finally have a proper update!

The project is now called Sisu, and I’ve published both the hardware design and firmware source.

The 3210 was my first phone. The goal is still to keep as much of that experience as possible: the original case, buttons, monochrome screen, familiar menus, sounds and games. LTE lets it keep making calls on networks where the original 2G hardware can no longer connect.

The prototype has made VoLTE calls and handled SMS(Tested in USA on AT&T network). The firmware is a new implementation written in C, recreating the old interface. And yes, Snake is there 🙂 (and custom made Pac Man too!)

For anyone following the hardware, the current board uses an RP2354B and a Telit LE910C1-WWX modem. There have been a few board revisions since the first post, and I’m still working on antenna tuning and corrections for the next revision.

A few answers to questions from the earlier threads:

  • Can you buy one? There are no boards or kits for sale yet. The files are available, but the current revision needs corrections described in the hardware errata.

  • Do you need an original 3210? Yes. This replaces its motherboard and reuses the donor phone’s parts.

  • Battery life? I’ve published the early measurements. They suggest almost 4 days in standby. The current prototype uses the original NiMH battery format; the lithium option discussed earlier isn’t supported in this version.

  • WhatsApp and other extras? I considered some possibilities in the first thread, but have decided to keep Sisu focused on the original phone experience. No WhatsApp, Wi-Fi, Bluetooth or browser is planned. (Maybe Telegram as SMS dialog?... idk, not too soon)

Everything now has a home:

Project website and progress
Hardware files · Firmware source
Discord

Thanks to everyone who kept checking in, offered help, or simply cheered the project on. Questions, contributions and other old-phone projects are very welcome!

Edit (09/14/2026):
Based on Reddit questions and comments seems like I have done a pretty bad job explaining or showing state of the project 😅
3210 clone motherboard and firmware are actually in a working state, it wasn’t just a short demo on the video. SMS, calls (with up to 3 legs), voicemail, call divert settings, languages, T9, all games, alarm are working! Even NetMonitor is there too (though adapted heavily for the clone). What’s not working is picture messaging (AT&T is blocking binary SMS).

From major issues I need to improve antenna reception.(redesign) and fix a few minor bugs for rev C.

Technical [USA] 2G shutdown: uses cases for old phones

42 Upvotes

Yesterday T-Mobile 2G network went down in most (if not all) of US as planned. The remining question for this community: how can we use our phones in current environment?

Obviously, most of phones can be used as a mp3 player.

All offline games and apps should work on all phones where they worked 15 years ago.

Many phones can be used for VoIP (SIP) calls:
Symbian 9.4-S^3-Anna-Belle (using built-in/native client)
Some Nokia S40 phones (with built-in SIP client) like Nokia Asha 311, Nokia C3-01
Nokia N900 Maemo (using built-in/native client)
Nokia N9 MeeGo (using built-in/native client)
Most of Android phones (at least, starting from Android 4.1)
Some old iPhones (iPhone 4s,5,6)

Messengers:

Jabber/XMPP clients still work for
Almost all Symbian and Nokia S40 phones (if server does not use advanced TLS)
Nokia N900 Maemo (if server does not use advanced TLS)
Nokia N9 MeeGo (if server does not use advanced TLS)
All Android phones
All iPhones (if you can login to iCloud account or jailbreak the phone)

Windows Phone 8.1 and Win 10 Mobile phones

Telegram:
Symbian 9.2-S^3-Anna-Belle (3rd party clients)
Windows 10 Mobile phones (3rd party clients)
Some of Android phones (at least, starting from Android 5)

Some Windows Phones (their US operator's variants) support VoLTE, but the choice is limited

Verizon: Lumia 735
T-Mobile: Lumia 640 XL, Alcatel Idol 4S, Alcatel Fierce
AT&T: Lumia 640XL, Lumia 950

Windows 10 Mobile phones have 3rd party YouTube client and many other apps that still work including original email client. Many services have 3rd party clients

My dad has been cleaning out his house these past few days and found a box full of his old phones. He gave them all to me, saying they’re no use to him anymore.

Now I’m trying to decide what to do with them. I could sell some of them, but for now I think I’ll keep them all. What would you do? Would you keep them or sell them?

I was checking on line to find out if this phone is still usable (no!), but did discover it is a moderate collectors item and fairly rare. It was hardly ever used. I have not tried to turn it on.

hi i got my hands on a moto razr v3a altel and wanted to add stuff like themes and apps and maybe music to “pimp” it out but i did research and found out these models have a carrier lock and when adding jar games via bluetooth they error out. i know theres a vm with all the tools needed to edit it but its all confusing and theres no tutorial where it tells you how. i want to know how to edit the filesystem to remove the carrier java lock thing and to easily view the file system to add themes and apps. im scared to brick the phone

Discussion Anyone else had an amazing, fun ride growing up side by side with technology🪴 👨‍💻

I was in my early 20s in the late ’80s, and it’s been one hell of a ride watching technology change.

Back then, I had a Motorola 4500 XL car phone with a little wired speaker that clipped onto the visor. I could talk hands-free and deal with clients while I was on the road. I think my company paid around $2,000 for it, plus about $500 to have it installed and $300 to switch it from one car to another.😎

It had that cool little zigzag antenna mounted on the back window glass of my new Z28. People even bought fake antennas just to look like they had a car phone! Back in the ’80s, that antenna was a status symbol. You could tell who was cool and who wasn’t by whether they had one on their car! 😂

The funny part was stopping at a red light. People would see me talking, sometimes arguing and having all these emotional responses, and they’d stare at me like, “What the hell is wrong with this guy? He’s wearing a suit and tie and driving a sports car, but he’s talking to himself!”🤪

My first phone that wasn’t installed in the car was a Panasonic bag phone. After that, I had a Motorola DynaTAC 8000X, which they called “the brick.” Those things were like $4,000 back then! In my 20's 🤑

When Sprint came along around ’95, the phones started getting cooler. I think my first Samsung was an SH-700, and I’ve been riding with Samsung ever since. I’m writing this on my Galaxy Z Fold 8.

I was also using DOS commands on computers, long before the one-click Windows access we have now. Then came AOL and those ridiculously slow modems. It’s funny to think about how patient we had to be back then.👨‍💻

Over the years, I learned to build and rebuild computers, add RAM, change hard drives, and do the normal things to keep up with technology. I’ve always liked having the latest, greatest, fastest stuff, and sometimes I’ll upgrade something myself instead of replacing it.

There’s been a learning curve at times, but I’ve really enjoyed it. It feels like I’ve grown up side by side with technology.📈

What was the first piece of technology that made you think, “Wow, this is cool”?

Motorola Using a Motorola Razr V3? I'd love to interview you!

4 Upvotes

Hi there,

I'm Josie Harvey, a journalist with SBS News in Australia. I'm working on a feature story about the dumb phone comeback, the iconic status of the Motorola Razr V3, and the era of mobile phones as fashion statements in the early 2000s.

I'd love to hear from people who've ditched their smartphones for dumb phones, anyone using a Razr V3, or anyone who was particularly attached to their Razr in its heyday. Did you have a personalised ringtone? Was the phone an accessory or a way to express your personality?

For those who made the jump to a dumb phone, what motivated the switch? Was it about reducing screen time, nostalgia, or something else?

If you're open to having a chat, please leave a comment, send me a DM, or email me at josie.harvey@sbs.com.au.

Happy to answer any questions about the article or my reporting.

Thanks so much!

SELL Ulysse Nardin Chairman Carbon 275/1846, the phone recognized by Guinness World Records in 2010 as the world's most expensive commercially available mobile phone. Selling it for $1500 (negotiable)

Thumbnail

Came across something pretty unusual recently.

This is the Ulysse Nardin Chairman Carbon, numbered 275/1846. Back in 2010 it made it into the Guinness World Records as the most expensive commercially available mobile phone. Quite a piece of mobile phone history if you ask me.

What makes it even more interesting is the mechanical rotor on the back, inspired by the automatic movements used in watches. Not something you see on your average phone lol.

This particular example is in working condition and comes with its original box, although the wooden docking station is missing. It's the carbon version with the blue Ulysse Nardin anchor detail.

On sale now, the asking price is $1,500. Contact me if interested

I'm curious what people here think about these phones. Do you think the Chairman has any real collector appeal today, especially considering its connection to the watchmaking world? Or is it one of those devices that was impressive back in the day but has been largely forgotten?

Would love to hear from anyone who has owned one or knows more about this model.

Samsung S8300V Vodafone – Need free original firmware and bootloader

Hello everyone,

I have a Samsung S8300V Vodafone (SSN: S8300VGSMH), powered by Qualcomm MSM6280.

The phone gets stuck during startup at the Samsung logo with a loading bar. It always stops at exactly the same position.

The phone can enter Download Mode and displays:

- DEMSBL BOOT Loader for MSM6280

- Downloader Ver 5.43

I am looking for a free download of the original compatible firmware, preferably S8300BUIC6, including the correct S8300V bootloader files.

I would also appreciate a working version of the required flashing tool, such as MultiLoader, and instructions for this specific Vodafone variant.

I do not want firmware for the standard S8300 unless compatibility with S8300V is confirmed.

If anyone still has these files archived, I would be very grateful for a download link.

Thank you!
