ZTE Blade A35 Common Problems & Troubleshooting (Won’t Turn On, Charging, Signal)
The most common hardware and software faults are covered below. Here is that fault list with sensible first steps. When a software fault is suspected, reflashing the stock firmware is often the fastest fix; for board-level faults, follow the teardown reference’s flowcharts.
Faults the teardown reference covers
- Battery failure
- Startup failure (won’t turn on)
- System crashes

- Side key fault

First things to try
- Confirm the fault with the built-in test: dial *#*#983#*#*, then *983*673636#, then *983*70# to run the automatic function test.
- For won’t-turn-on or random restarts, charge for 30 minutes with a known-good charger and cable first — a flat battery can look like a hardware fault.
- For crashes, freezes or a fault that started after an update, reflash the official stock firmware.
- For no-SIM / no-signal, reseat the SIM and test a second known-good SIM before opening the phone.
- If a hardware fault remains, have it checked by a qualified repair technician.
💡 If a fault persists after these checks, have the mainboard inspected by a qualified repair technician.
