@Уважаемый Павел,
Какая прошивка у вашего Cudy TR30 (TR3000)? Это последняя версия прошивки 2.4.7? Если нет, пожалуйста, сначала обновите прошивку. Затем проверьте еще раз.
“Здравствуйте! При подключении к Cudy TR30 (TR3000) LTE модема, нет соединения. В настройках Cudy USB соединение неактивно. Что можно сделать?”
@Dear Alan,
So, why do you think it is the 256MB version. The 256MB version is only available for sell in China. The words on the label are in Chinese language, please have a check.
“Regarding the previous issue (failure to recover TR3000-256MB), I was finally able to revive it from being bricked using TTL. My router itself has no any hardware faults. I discovered that the NAND chip’s memory size differs from what is indicated on the box or label. This mismatch led to flashing the wrong version, causing it to become bricked and continuously reboot.
The chip inside is an ESMT F50L1G41LB, which can be broken down as follows:
F – Manufacturer: ESMT 50 – Product Collection L – Low Voltage (DDR3L) 1G – Density: 1Gb (Single Capacity) 41 – Organizational Structure: x16 (16-bit wide) LB – Packages and Versions
The capacity of a single unit is calculated as follows:
1Gb ÷ 8 bits/byte = 128MB
I hope you all don’t have to deal with the same issue I experienced. I’ve reached out to sales@cudy.com but haven’t received a response yet."

@Уважаемый Павел,
Пожалуйста, следуйте этой инструкции шаг за шагом. Если это не поможет, попробуйте выполнить эту операцию на другом компьютере.
“Здравствуйте! После прошивки роутера Cudy TR30 (TR3000) на OpenWRT решил прошить на заводскую прошивку и видимо бэкап не прошился. Теперь роутер не загружается и не заходит в web панель управления. Как можно это исправить?”
