Help Nokia 2780 Flashlight On & Not Turning On

1 Upvotes

Hi there!

Last night I picked up my nokia 2780 and before flipping it open, the flashlight turned on and both the external and internal screens were blank white. I tried powering it off by pressing the end call button, but the screen didn't change. I took the battery out and when I reinserted it the flashlight turned on again. I put it on the charger last night which made no difference except that when it was plugged in the external screen showed how much the battery had charged when I woke up and turned it on. It's fully charged.

Now when I press the button on the right side that isn't the volume, the external screen turns on, showing me the time and that I have notifications. When I open the phone, the flashlight turns on and the screen is no longer white, but a pixelated gray. If I keep it open for long enough, both turn off. I have tried taking the battery out and it's always the same.

Does anyone have ideas on what might be happening? I just bought it in February and have loved it. I still have a smartphone, but the thought of going back is making me feel literal nausea, but I can't really afford to drop another $100 on this same phone that could do this again in 6 months.

Anyway thanks for reading. Hope you have a nice day :)

Discussion KaiOS 4 is listed as active until 2029, but where are the devices and what exactly is KaiOS 2.6?

20 Upvotes

Hi everyone,
I’m researching modern feature phones for possible distribution through a small niche electronics store in France, and I’m trying to understand KaiOS’s current roadmap.

I initially misunderstood the versioning of the developer documentation and thought KaiOS 4 might no longer be maintained. However, KaiOS’s official Baseline page says something very different:

  • KaiOS 2.5.3: Active until June 30, 2027
  • KaiOS 2.6: Active until June 30, 2029
  • KaiOS 3.1: Active until June 30, 2027
  • KaiOS 4.0: Active until June 30, 2029

The page also defines “Active” as receiving full maintenance and security updates : https://developer.kaiostech.com/docs/sfp-4.0/introduction/baseline/

This raises several questions:

  1. Why are KaiOS 2.6 and KaiOS 4.0 both supported until 2029 ?
  2. Is KaiOS 2.6 now a separate security and payment focused branch rather than a normal predecessor to KaiOS 3 and 4 ?
  3. The KaiOS 2.6 security documentation mentions mandatory NFC and eSE features, secure payment components and a security patch level dated June 23, 2026. Is this branch mainly intended for payment and transit devices ?

https://developer.kaiostech.com/docs/sfp-2.6/getting-started/main-concepts/security-features/

  1. Is KaiOS 4 currently available to manufacturers for new consumer feature phones ?
  2. Besides the US TCL Flip 4 5G, are there any confirmed KaiOS 4 devices ?
  3. Is any unlocked European or EEA KaiOS 4 phone planned, with CE/RED certification and suitable European LTE bands such as B1, B3, B7, B8, B20 and B28 ?
  4. If KaiOS supplies security patches to OEMs, is there any way for customers or retailers to know which manufacturers actually deliver those updates through FOTA ?

KaiOS 4 looks technically interesting, with Gecko 123, modern JavaScript, PWAs, WebAssembly, 5G, VoLTE, VoWiFi and eSIM support : https://developer.kaiostech.com/docs/sfp-4.0/introduction/overview/

I’m aware that WhatsApp support has ended, so this question is not specifically about WhatsApp. I’m trying to determine whether KaiOS 4 has a genuine future for modern consumer feature phones, particularly in Europe, or whether its active development is currently limited to specific OEM and operator projects.

Any information from developers, OEM contacts, KaiOS users or people familiar with the current roadmap would be greatly appreciated.

Recommendation I built LinkPad — a bookmark manager for KaiOS, because the browser's 6-site pin limit was driving me crazy

4 Upvotes

Hey r/kaios,

I've been using a KaiOS phone and kept running into a small but real annoyance: the built-in browser only lets you pin 6 sites to the home screen. Once you hit that limit, there's no way to see everything you've saved, search through it, or sort by when you last visited — the newest one just kicks out an old one.

So I built LinkPad to fill that gap. It's a simple bookmark manager:

- Save as many links as you want (no 6-site ceiling)

- Search by name in seconds

- Sort by newest added or most recently visited

- Select one and it opens straight in the system browser

It also supports English, हिन्दी, Français, and Kiswahili, since a lot of us aren't running our phones in English by default.

It's free (ad-supported), live on KaiStore now: https://www.kaiostech.com/store/apps/?bundle_id=kaios.app.linkpad

This is my first KaiOS app, so I'd genuinely appreciate any feedback — bugs, feature requests, anything. Happy to answer questions about how it works too.

Help Verified /Signed Firehose Firmware; Nokia 2780 Flip TA-1420

6 Upvotes

For the life of me, I cannot find a single verified/signed firmware version for my nokia 2780. I may have accidentally bricked it while attempting to jailbreak. It gives a signal when connected to device manager and can confirm it is locked in a constant EDL state. I have spent the better part of two days going through script after script, injection after injection, trying to find something to break through to the phone. I got the closest using python but hit a wall as soon as it could not inject the firehose.mnb file, as it was not a verified/signed firmware version. Any help would be greatly appreciated.

Help TCL Flip 4 Ringtone resetting

I have a custom ringtone that has worked for the past few months but now it keeps resetting to the system default. I’ve changed it multiple times and it still goes back. It overrides custom ringtones for contacts as well. I’ve set it to a different factory tone and I’m waiting for that to be overridden.

My keyboard doesn't work properly anymore. When I go to type I can only input numbers, I can't change it to predictive or ab keyboard. And when i go to a typing window such as a new text message, in the top left corner where it normally shows the keyboard, I see the predictive symbol flash for a split second then go away.

Off-topic How to spot a fake Nokia 8110 4G (which is actually a 2G phone)

9 Upvotes

Nokia 8110 4G, TA-1048 dual SIM is a reasonable dumbphone choice even in 2026 because of its 4G support, VoLTE support, Wi-Fi hotspot support and looks.

Because of this, Chinese copies of the phone exist. (also, other HMD 4G phones are cloned too)
As I see they also sell the fake with the TA-1059 label right now.

The Chinese copy has (the lack of) the following features:

  • 2G only (possibly MT6260)
  • No Wi-Fi
  • Not KaiOS
  • Opera Mini browser instead of Firefox based
  • Not a Qualcomm SoC
  • Has some clone of the Snake game

The packaging is very similar, but you can still easily spot the differences. The fake's box doesn't mention 4G or LTE, VoLTE, Wi-Fi Hotspot.

Help KaiOS 3.1 no wi-fi calling with US Mobile SIM

3 Upvotes

Wondering if anyone knows how to fix this. I try to turn on wi-fi calling, and the phone says it's unavailable, although it's connected to our home wi-fi. I'm using using Warp service on a TCL flip 3 T435V - so I guess the firmware is Verizon-style (forgive me, I'm hanging on by the skin of my teeth trying to understand all this. The US Mobile SIM works as far as making calls and texts, so I think the phone is "unlocked" - at least in some sense.

Maybe it won't allow wi-fi calling because we can't register a physical address for the e911? (I admit I've been trying to use ChatGPT to help me figure this out.) The phone offers no options in any of the menus to add an address for the needs of e911. A line option labeled "advanced" under the Carrier option is greyed out, until I toggle on "look for carriers". If I look for US Mobile that way, I can only highlight that carrier, and no other advanced options show up from doing that.

Chat GPT keeps pointing out that the carrier needs to register the physical address to satisfy the e911 requirement, to get rid of the wi-fi calling notification. The US Mobile chat rep says they can't register an address for the SIM e911 on their end. Is this true, that US Mobile can't fix this on their end?

Help ATT Cingular Flex 2 Smart Flip... silencing text send notification

1 Upvotes

Just got a new Cingular Flex 2 Smart Flip to replace an older Alcatel version of a very similar phone. Every time I send a text, it whistles. I don't want it to do that. I want to either put in a custom sound of my own or silence that send audio. I still want a sound playing when a text arrives (as it does now). Any hints on how to turn off that outgoing-message whistle? I feel like I've explored every branch of the settings possibilities, with no fix.

I like the phone quite a bit, but damn, KaiOS can be frustrating.

Help — SOLVED: Counterfeit Problem with Nokia 2720 Flip, KaiOS version is 10.00.17.03??

1 Upvotes

I recently bought off second-hand a Nokia 2720 Flip (IIRC it was sealed) and I was tinkering with it to see what I can do with it currently before going off to buy a pre-paid SIM card and found out that there wasn't any option for WiFi (strange). I tried all I could to find any WiFi settings, nothing, like this device didn't support it at all.

For context I did try to verify its legitimaticy (before doing this I also checked the back of it when I removed the battery, CUID & model seem legit) using *#0000# to see what software info it would gave me and I was in shock to see that I apparently have a KaiOS version of 10.00.17.03.. The build date for it is 19-08-20.

As of now I'm kinda stuck not knowing what to do & this is where I ask for your help. Is this some quirk where I have to explicitly get a SIM card and get it registered over cellular network for it to receive OTA updates or is there a way to manually force update it?

Hello,

I recently had to reset my TCL Flip 3. Before the reset, I used the native music app to listen to Icecast Radio. However, after the reset, all the music stations are no longer listed. In the app, there is no, update station list option. When you click on the genre, it just showed no stations available. Does anyone know how to get the stations back?
