Copy of MR5100 downloadable firmwares

Post by jcrm2 »

Do anybody know where I can get a copy of MR5100 firmwares. I would like to manually either downgrade or upgrade the firmware. Right now im currently on Oct 15th 2020 firmware, NTGX55_10.25.15.02.

I see their are updated firmwares dated,

Dec. 18th 2020, NTGX55_10.29.10.00
April 28th 2021, NTGX55_12.03.06.00_ATT_02.11

or perhaps MR5200 firmwares as well. I can possibly flash those since It's the same device.

You will have to unlock the bootloader, (it is secure boot enabled device) and need an exploit to get passed the efuze, the firmware is crypted, if you can manage to do all that this is what you will get.
Also those updates are not firmware, they are basically just small config files and such that increment the firm and linux version counters, the full firmware is about a gig and a half and to big to be loaded over the air, that would cost them a fortune in data.

If you try to load firm to it without removing security you will bork your device and it will not boot up anymore

Hey Rich, if we were able to scroll a little left in that Win Explorer window shot there we wouldn't happen to find an 'ST Micro' folder would we? lol ;)

Not sure what you mean, what is 'ST Micro' folder?

EDIT:
Ok I see what it is by google it, to answer your question no I do not use it, I mostly use IDA, olly and winhex along with qtool and many custom tools I have made over the last 30 years

Was just joking around really, I seen you kinda organize your 'projects' by folder. ST Micro made security MCU that were used in smartcards for TV and such for years such as the st19na18 (24x). As much as you know about dumping etc., I wouldn't have been surprised if you had a work folder for it on ur machine is all. Those were fun times for me, was obsessed with that hobby lol.

Sorry for taking the thread off topic..

You can pull firmware directly from the device via ADB such as boot,sbl,recovery,tz,etc. Will need to push arm static compiled mtd-util binaries to the device to create system ubi image and modem ubi image to be loaded via fastboot.

sys_reboot bootloader in telnet or adb will get you to bootloader/fastboot.
