Any update for JioFi2 M2 ?
[Upgrading, Modifying and Unlocking] joste10:
I am trying to convert my old JMR540 into a wifi repeater, connecting to my home wifi and creating a secondary AP(with a different SSID and bridging to the home wifi) which I can use for my IOT devices(just a pi and a few esp8266’s).

As a start, I tried creating a station using iw command and tried connecting to home wifi using wpa_supplicant, but failed to connect.

Could anyone give me an idea on how to connect JMR540 to my existing wifi network?

Additionally, how can I make it work as a repeater? It would be helpful if I can get the steps.

I am accessing the JMR540 using UART console through the pins soldered onto the board

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Need Unlocked Firmware for JIOFI JMR815....
[Upgrading, Modifying and Unlocking] genuinejoe:
****

Dear Abhi,

Really useful steps. Thanks.

I tried it on Windows 10. But the only problem I can guess why its not working is maybe because the “Device Manager” in Windows 10 recognizes the JioFi router as “Android”- not more than that. The other steps I followed as you mentioned in your steps.

I have attached the screenshots of the JioFi admin screen. Also the screenshot of Device Manager. In the cmd command prompt, after entering the “fastboot devices” command; no response is provided by the system. That is the main issue. PN: I connect JioFi to the laptop using USB-A cable. Any suggestion/help would be most appreciated.

​

Hi, everyone. I hope you're all doing well.

We need your help with something small.

As you all know, Jio and all other carriers have recently raised their plan prices. This makes it a little tough for us to afford our plans.

However, I may have found a hack that could help, but for that, I need your help.

Basically, if we're able to change the IMEI number of our JioFi to be the same as a Jio phone, we can use Jio phone plans with our JioFi.
[Upgrading, Modifying and Unlocking] Vishal_01:
Bro there's no need to do that as most jiophones that are old can be flashed with a modified firmware and it's available for us thanks to devs.

If somehow vpn service can be implemented to the jiofi we can use that as free unlimited internet device for us in non-recharged jio sim.
[Upgrading, Modifying and Unlocking] mynameiskhan7:
Yes, I totally agree with that, but the problem is that in JioPhone, we can't get high-speed internet.

Can you elaborate on the VPN service?
[Upgrading, Modifying and Unlocking] Vishal_01:
so as some telegram channels provide vpn files that can get us free internet without recharge in jio sim like

[Upgrading, Modifying and Unlocking] Mysteriouslog6:
I was able to fix it! Just put the sim in.....

@abhimortal6 How did you modify the rootfs? Planning on making a few more mods to the filesystem It is getting detected as a UBIFS file system but a lot of the extractors seem to be facing errors etc.
[Upgrading, Modifying and Unlocking] abhimortal6:
UBI read/extract tools available on git works partially it’s just matter of changing offsets. I do not have actual configurations right now but comparison with a generic UBI image will let you see things more clearly hope that helps. FYI device’s partition table gets easily corrupted, allocation is weird in this devices OG devs knew this so device have a recoveryfs if OTA updates fails. You’ll need to trim out UBI after packing.

[Upgrading, Modifying and Unlocking] abhimortal6:
Hello kind sir, I humbly accept your gratitude. As I've previously said dumping and reverse engineering requires hardware or in simple terms physical access to the device as it requires constant trial and error with patched software to test on device. If you are familiar with Linux, reverse engineering ARM binaries and embedded devices you can perform these task on your own. I'm trying to get hands on these devices via OLX but until then there's nothing I can do about it.

One problem, after flashing this firmware the device gets pretty hot when you're downloading something. I had a JMR541 model which was not flashed and I tested with JIO sim, for downloading (content from internet) about 30 minutes the device was just normally warm. After that I flashed this firmware and tested with Vi sim and tried to download something, the device became exceptionally hot! So hot that I couldn't even touch it. Could it be something with kernel? @abhimortal6, please look into this matter.

Hi,

Successfullu unlocked JMR541, working fine but getting restarted automatically. please help
[Upgrading, Modifying and Unlocking] imprasenjitroy:
Confirmed Working with JMR541. Thanks @abhimortal6 🙌

​
[Upgrading, Modifying and Unlocking] abhimortal6:
Kernel is not modified and is stock. Device’s power consumption does increase in higher speeds. Extreme heating is a sign of battery failure or possible shorting in hardware. Check if device reboots while using without battery.
[Upgrading, Modifying and Unlocking] abhimortal6:
This is a sign of battery failure as battery is unable to deliver required power, try using without battery on 2A 5V adapter.
[Upgrading, Modifying and Unlocking] rockydares:
While on battery JMR541 became extremely hot and automatically switched off. Battery condition is fine. While on no battery it became too hot and automatically rebooted (charger is not 2A). The JMR540 doesn't reboot in both conditions but simply turns off the hotspot. I would check with a 2A charger then I'll share the results. Anyway, I've never seen jiofi exceeding 30mbps until I flashed this firmware! That's why I capped speed to 1.2MB/s while downloading.
[Upgrading, Modifying and Unlocking] ruturajjena:
@abhimortal6 any idea if we can enable carrier aggregation in JioFi.

my phone with carrier aggregation has speed upto 80mbps on jio where as 5mbps in Jiofi without it.
[Upgrading, Modifying and Unlocking] rockydares:
Believe me, even if you achieve 80mbps the device won't be able to withstand the heat, it will be burnt after few minutes. I get 30+ mbps on Vi sim and cpu is almost 65% occupied and seems like the device will be melted down from the heat it generates.
