FX2000 INFO & HACKING THREAD

Post by Rich Hathaway »

FX2000 / FX2000-3
This is the downsized version of the fg2000 is a lot easier to work on than the fg, for one it does not need to be disassembled to find bootloader/fastboot mode,.
I have 2 of these both are the fx2000-3 variant so all the info below in this post is based on that model.

I was able to make full firmware for all parts without taking it apart.
it is similar to other Inseego / Novatel devices as far as
root pass, IMEI, MEID, ESN, TTL, FID etc.
it is also similar in that it is Linux/android based on one side and the other is a triple-layered stack of ubi over ubifs over mtd filesystem, other recent Inseego devices are the same.
Below is some of the pertinent ubi info

for me, it works well on Verizon AT&T and Tmobile with the proper adjustments/magic
I am hoping someone else has the fx2000 variant and will post similar info for that variant for comparison in this thread.

Yes it is possible but you have to enable the ports first so further work can be done to it, I did it by making modified firmware
with the ports enabled on it, maybe you can find an easier way or do the same

greetings and salutations great ones

I come with n00b questions from an old bricker/breaker.

So these new cell devices are adb accessible? I'm seeing that more and more. It just blows my mind (not that it takes much but I was screwin with basebands on the original moto's)

I haven't tried going into debug with my inseego yet. Before I do are there any words of caution you more experienced folks could give? Does debug normally come on by default or will I need to use something like a modern buspirate to try to get some uboot action?

any firmwares I can binwalk out there at all would be appreciated. my model is a TMobile. I would love to dump the partitions using fastboot or whatever .. but probably wouldn't we all? ROFL. It can't be that easy off the rip can it?

Thanks and respect to those with knowledge/skills and any inclination to share.

I'm a noob to this forum, but this is the only place I've been able to find info on this device. I got a used FX2000 for a good deal, and was wondering if it was possible to change the IMEI and how to do that.

But fastboot don't see any device ...
Also i cant change the driver , in Windows it is detect it as Qualcoom HS-USB Diagnostics 900E (COM7) , and can replace it as Google USB ( as i know devices with this driver is detected via fastboot).

900E is download mode, not bootloader.
fastboot mode on these is hold reset button pop in battery keep holding reset and plug in usb and keep holding reset for 5 seconds or until your pc dings then will be in fastboot mode.

Oh ya my bad this one just hold reset and plug in power while usb is connected and hold for 5 seconds after that,
sorry I have been in sierra threads today and was thinking sierra not inseego lol.
If you still only get 900E it means the boot part is borked and you will need to use a testpoint or need a working loader to load it from 9008 mode

But is it sure , that mode 900E is enough to put loader via edl , or maybe exacly 9008 mode is needed ?

That depends on what you mean by edl, edl to me means the mode (emergency download mode which is 9008)
if you mean edl as in BK's tools then I do not know I dont use BK's edl tools except for the keygen.

Ok , so what is 900E ?

And if it is not emergency download mode , then loader will not help anyway , first have to be set to 9008....

900E is download mode which needs the loader NPRG-SDX55 (Normal Program Mode)
9008 is emergency mode which needs the loader ENPRG-SDX55 (Emergency Program Mode)
