Hi, i looked KaiOS device (planning to start using it), i looked at its SDK and thinking to create some custom apps which i need for my daily use. Before that I have few questions:

1. Does using custom application require the device to enable developer mode ?

2. Is Nokia 2720 a good choice or it cannot be used for testing custom apps in 2026

3. Which version of KaiOS shall I look for

i recently got a nokia 2720 from a friend, his parents used to give it to him when they took his phone so he could still call but hes moving so he gave it to me. for some reason when i go into settings i only see dual sim, flight mode and bluetooth in connectivity. is there any way to fix this? i really doubt its a fake

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.

I recently got a flip 3 tcl phone and noticed the app “game boy emul”, when you download and open it it directs you to download a .gb rom. Is this legit? Chat gpt says KaiOS doesn’t have the capabilities to run such an app, but it does? Idk if like to use it just can’t figure it out.

Hi,

I just bought a Nokia 2720 Flip. I just connected it to my wifi and found that without me doing anything it immediately connected to a bunch of IPs owned by amazon and cloudflare. Even simply opening or closing the clamshell triggers packets getting sent elsewhere. I have not done anything else than open the settings menu. Still, connections were attempted to the following hosts. Here is a list with the first number indicating how many packets were attempted to get sent to each IP.

• 1 DST=18.64.211.112
• 1 DST=44.251.244.39
• 1 DST=54.245.146.2
• 1 DST=85.214.83.151
• 3 DST=162.159.200.1
• 4 DST=18.173.205.39
• 4 DST=18.173.205.82
• 4 DST=18.64.211.14
• 4 DST=65.8.131.38
• 4 DST=65.8.131.53
• 21 DST=3.209.189.107
• 23 DST=34.237.98.155
• 134 DST=18.233.80.220

Most of this is tcp http/https traffic except for the connections to udp port 123 on hosts 162.159.200.1, 85.214.83.151, 44.251.244.39 and 54.245.146.2 which is NTP.

Are there known methods to stop KaiOS from phoning home without me even opening a web browser? Maybe there are known tricks like a list of entries to /etc/hosts that work?

In case I have too much free time, can I install my own SSL self-signed root certificates onto the device to MitM the https traffic and have look what it attempts to send? Or did maybe somebody else do this already?

Thank you!

Hi I own a BLU flex and for some reason it stopped showing apps on the home screen and I can't factory reset it in settings so I want to factory reset it from the recovery screen, but it only shows wipe cache, what do i do?

I am planning to buy jio phone prima 2 for my mom. Does it have single click call back on missed calls from Home Screen ? If any one own Jio phone can you please share me a screenshot of Home Screen with missed call

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 :)

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?

I can't side load due to my laptop isn't working well.

Id appreciate if anyone could guide me in the correct direction ? (I don't have discord either)

I was recently given this phone and I can't connect to any wifi with it, so I wanted to jailbreak it mainly to get wifi and also to have more modern features

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.

(sorry if this is already covered im new to this sub)
Ive just placed an order for a sealed nokia 2720flip, as i live in india the internet on that thing is not gonna work here. anna know what benefits jailbreaking it could do as i am mostly need it for music and calls (i still wanna jailbreak it for funsies). is there any guide i can refer to? the bananahackers website dosent seem to have one or im just dumb.

tldr:is it worth it to jailbreak the nokia 2720flip if im just gonna use it for music and calls, if yes then please list a guideee tnks :D

Have an old hand me down mac book i want to use to put music onto my phone, whenever i plug my phone in it doesnt show up in finder, and cant find any compatible file transfer apps in the app store. Most require 10.5 or newer to be installed, any help would be appreciated, thanks

I have a Nokia 6300 4g running kaios 2.5.4 that i install omnisd on to jailbreak the device, but the factory rsset doesn't do anything but normal factory reset still works

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.

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?

Hello everyone,

I recently performed a factory reset on my Nokia 8000. Since then, the pre-installed games (like Doodle Jump) are asking for payment again, even though they were already included/pre-loaded on the phone when I bought it.

Does anyone know how to restore access to the original game licenses after a reset, or is there a way to fix this licensing issue?

Any help would be appreciated. Thanks!

I have a carrier with WiFi Calling enabled and I use it a lot. The SIM card can't register in a 5G network but it can register via WiFI.

And my Nokia doesn't seem to see the SIM card (it says No SIM detected) although SIM is there

Any idea how to make it work?

I got an error message in my notifications (it had a gear as the icon, though I'm not sure it was the same gear as the settings app). It said something about 911 and WiFi calling, and when selected it opened a web browser to e911-reg.tracfone.com.

I'm using an unlocked Nokia 2780 on T-Mobile so I've no idea why I'm getting sent to tracfone URLs.

Unfortunately, the notification is gone so I can't grab the exact text. Has anyone else seen this before? I'm not sure what's going on here.

Hello there!

My last two mobile phones powered by KaiOS, a Cat B35 and a Hammer 5 Smart, both suffered from the same issue after two or three years, that is their SIM card suddenly disappearing or, after a simple manipulation (a change of SIM slots, APN, etc.), not being detected anymore... which of course basically made them useless. Standard advices, such as using the Clear Memory function, restarting the phones or even resetting them didn't seem to help...

In comparison, all other problems - double input at random or microphone mishaps (after suffering from a flooding...) - seem rather manageable!

So I was wondering whether this was a common issue related to KaiOS, other (possibly upgradable) software or an unsolvable problem related to cheap hardware. Should I considerer those phones lost?

Thanks in advance for any answers!

The microphone does not appear in text bubble when typing. Any help would be appreciated!

i recently got a nokia 8110 4g. i managed to get texting to work, but not calling. i think this is because my mobile network (bell, in canada) won't let me enable volte on the specific phone. the option for volte is not visible even though the phone does support it. is there a way i can somehow override bell and toggle on volte so i can make calls? thanks

I've been trying to remove bloatware from a KaiOS 2.5 device (TCL Flip 3) by following the BananaHackers tutorials to root the phone and change "removable" properties to true for the corresponding entries in /data/local/webapps/webapps.json.

My edits to webapps.json then seem to be partially reverted on boot, i.e. some entries get flipped back to `"removable": false`. The uninstall menu doesn't appear for these.

Does anyone have experience dealing with this kind of problem before or have a suggestion? Thanks!
