***Update***

Using the usbloader.bin file found on the modem I was able to flash the downgrade firmware and the upgrade firmware/webUI!! On the home stretch!!

However I now have the imei and serial number wiped out because of the use of the balong file that deletes the nvram. This is going to be ok in the long run because that is why I am doing this in the first place, to change the imei and hardware info. But I cannot get the AT commands to work now.

It will let me run any AT^DATALOCK="********" code I want to and it returns OK but I am assuming that is because the nvram is nuked and it doesn't care but I am not sure 100%.

When I run the commands to change the IMEI (AT^CIMEI="***************") and the Serial Number (AT^NVWR=6,20,4a 35 48 42 59 41 39 33 43 33 30 34 32 31 37 33) I am getting +CME Errors. When I run the IMEI command I get error 1 or 10 all the time and then when I run the Serial Number command I get the +CME Error: 50. I am converting the serial to hexadecimal properly and have triple checked that as well.

I looked up the CME errors and couldn't find much but for Sierra cards the CME Error: 50 is a sim card error saying there isnt one there. I confirmed though that the device sees the sim as it shows up in the Device Information page. So I don't think that is the problem.

Any ideas on this last part of the process?

try this, ensure to insert a working sim into the device
Code:

AT^NVWREX=50502,0,128,8F 29 FF 8E A8 CA 34 89 78 73 18 BA 9E F5 9C 64 0B A4 DB 81 DC 03 45 6E 72 DA EC 6A 0C 7C 90 65 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 8B 8C F4 B5 AF 0C F2 2C FE E0 F4 46 9C CF 47 95 36 71 1F 1C BF 05 7F 84 AB A9 F2 92 89 33 3C 12 01 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

if Ok then send
AT^DATALOCK="00000000"

if Ok then retry the IMEI command, you can try other IMEI commands below (take note that the 15 digits are split apart and 0 is added before each digit, also there's a 00 at the end of both commands and the imei starts after 0,16)
Code:

E.G 123456789012345

AT^NVWR=0,16,01 02 03 04 05 06 07 08 09 00 01 02 03 04 05 00
AT^NVWREX=0,0,16,01 02 03 04 05 06 07 08 09 00 01 02 03 04 05 00

for SN, use 6,16 instead of 6,20


btw did you try using usblsafe and it didn't work?

Those worked!! Thank you so much!

I am soooo close. I just realizsed that the firmware/webUI thagt is got working isnt for this model SMDH. Soooo now I am going through and trying to find a firmware with a UI that will work on here... I have a bunch of firmwares that I can get to flash on here but haventg found any that are working with any of the webUI's that I found...

The firmware/webUI that I had gotten to work prior is this one: E8372h-153_update_21.329.01.00.00_WEBUI_18.100.11.04.03_RE5_U_AT_F
That ^^ is a sweet customized firmware with a ton of options but it has all the wrong operating bands for my 510 models...

These are the 3 firmwares that I can get to install but I cant get a UI to install and then open in the browser after installing them: 21.180.99.04.00, 21.180.99.05.00, 21.180.99.07.00

I have tried half a dozen WebUI installers alongside those but none seem to work.

This is a screenshot of the firmware that I was able to install but is the wrong version/bands.

I am willing to pay for someone to make a version of this firmware/webUI that will work on the following 2 models: e8372h-510 && e8372h-609

Any chance of this ^?

I have uploaded the file for the pictured FW for your review. https://file.io/SecJNiGxqNQc

it makes sense now why AT commands worked, because you were on a firmware with AT enabled. firmwares labelled with U_AT or M_AT are modified to allow AT and extra added features too. i also don't think firmware would affect signal reception though (i might be wrong) but is there a frequency you should get but aren't i.e while using the firmware from h-153?

i think you might want to first try out a different webui on the current h-153 firmware (this will help verify if the webui works on your variant) then you can proceed to test with with the other 3 firmwares you listed above. i want to believe that any webui for e8372 should work
webui @ https://www.mediafire.com/file/8lcs9bjly...1.zip/file

h-608 (not sure of it's contents but you can also check it out, it shares some bands used by h-510) @ https://www.mediafire.com/file/dmxd2x0dd...y.rar/file

OK great!
I think the problem lies with my procedure for flashing those. I cant seem to get them to work. I can sucessfully flash them if it is immediately after flashing the firmware (Preceded by needle method and usbloader) but I cant get the webpage to open ever and there arent any apparent errors.

Does my procedure seem correct or am I messing this up?

Thank you so much man.

Oh and also... Yes. None of the auto connect features or band selection/network registration seems to be happening. But I havent tried the python web api yet. Ill try that now on that cool 153 one. Tks for the idea there.

I cant seem to find any other 510 firmwares. Ive tried other search engines too.

Ive messaged the devs on the repos for balong and some of the guys in 4pda but I cant get anybody to let me pay them to just make me one. Lol. I dont know C and dont have the time to dig into that pit right now as much as Id like to...

If you have any insight on who or where to go to just pay for a solution that is what we need that would be awesome! @justscribner on TG and skype.

On the other hand... If you happen to have experience or know someone who does with "sewing" these things up with the mods we need then I am willing/eager to just get in and do that part my self if you know the cliffnotes. Ive read a bunch of the code in those bash scripts but not enough to have a full grasp on it.

Hello, would you have the fw that you used in the 510 model? Yesterday mine did not get any more signal, I tried to reset it and it did nothing, I tried to update and it gives me an error in user data and the moden does not turn on, if it detects it in download mode but I cannot install any fw and I always use it I am desperate, I appreciate if you could send me the files. thank you so much
