Furthermore, on E/F/H series you have to disable OTN support in service menu to prevent automatic online updates to be done without prior notice.
How To Disable Firmware Updates
In case you notice OTN support is greyed out, check second post of this thread for how to block updates on router level.
To be mandatorily done from J and up if you expect root one day, don't tell you were not warned!!
- E/F series
- All ("smart"=having Smarthub) models on all firmwares are rootable, using procedure(s) found in public forum.
- H-series
- Rootable versions are corresponding to firmwares "up to October 2015". For now no root possible after that deadline.
- T-MST14DEUC: firmware less than 2790 ("less than" means NOT included !!)
- T-GFPxDEUC: firmwares less than 1290
- T-NT14UDEUC: firmware less than 1050
- T-GFSDEUC: all firmwares (not concerned by Oct.15 limit)
Beware that we don't have enough non-European models feedback to provide reliable info. Same goes for some low-ends such as T-NT14M.
