Samsung Galaxy M01 Motherboard Service

Published by TurboFix, Hyderabad · Last updated 8 October 2026 · 2 sources

Quick answer

A Galaxy M01 with a board fault — no power, no network, no charging despite a good port and battery — can often be fixed at component level on its Snapdragon 439 board, keeping your data and IMEI. A replacement motherboard is the fallback; it starts with empty storage and a different IMEI.

The Galaxy M01 is a 2020 Galaxy M phone built on the Snapdragon 439 (4G) with an LCD display. Its motherboard holds the processor, memory, storage and radios, so a board fault can look like almost anything — a dead phone, no signal, no charging or constant restarts.

This page explains how board faults show up on the Galaxy M01, what we rule out first, when board-level repair is possible, and what changes if the motherboard has to be replaced. We serve customers across Hyderabad at their doorstep, by pickup, or at our Nampally studio.

Screen dark but the phone rings, vibrates or shows up on a computer
Faults that started after a drop or liquid exposure

What makes the Galaxy M01's board different?

Chipset: Snapdragon 439 (the version sold in India). Snapdragon is Qualcomm's platform. Snapdragon phones use Qualcomm's matching power-management and radio chips, so power and network faults are diagnosed along that platform's circuits.
Display: LCD — the backlight is driven by circuitry on the motherboard, so a dark screen on a phone that still rings can be a board fault rather than a broken display.
Network: 4G only — this model can't connect to 5G, which is by design, not a fault.

Where does the Galaxy M01 fit in Samsung's 2020 Galaxy M line-up?

Samsung's 2020 budget phones in India ranged from entry models on MediaTek and Snapdragon 400-series chips to mid-rangers built on the Exynos 9611, and were all 4G-only.

Among the Galaxy phones on our list, the Snapdragon 439 is used only in the Galaxy M01, so its board-level parts are specific to this model.

Board-level repair or a replacement motherboard?

Fixing the failed component on your Galaxy M01's Snapdragon 439 board keeps your data and IMEI. A replacement Galaxy M01 board starts with empty storage, reports a new IMEI and must be free of the previous owner's locks. On a 2020 phone, replacement boards are usually second-hand or refurbished, so component-level repair of your own board is often the better option. Our Samsung motherboard service guide explains data, Factory Reset Protection, Knox and IMEI in detail.

What do we rule out before blaming the Galaxy M01's board?

Battery: a failed battery can look exactly like a dead board, so we test with a known-good supply.
Charging port and cable: a damaged USB-C port or sub-board stops charging without any board fault.
Display and backlight: we check whether the LCD is lit before blaming the board.
Software: a phone stuck on the logo may only need a software reinstall — though that erases data, so we discuss it with you first.
Liquid damage: we inspect for corrosion around connectors and chips.

What should I check on my Galaxy M01 before booking?

Note the model number from Settings > About phone (it starts with SM-) if the phone still turns on — it tells us exactly which board variant you have.
Know your Google and Samsung account passwords — Factory Reset Protection will ask for them after board work.
If the screen is dark, check with a torch whether a faint image is visible and tell us — it separates an LCD backlight fault from a dead board.
The Galaxy M01 launched in India in 2020. At this age, weigh the cost of board work against the phone's value and how much the data on it matters to you — we'll help you compare honestly.

What do we test on your Galaxy M01 afterwards?

Power-on, charging and battery drain at idle
Calls and 4G mobile data
Wi-Fi, Bluetooth and GPS
Fingerprint and face unlock
Front and rear cameras, speakers and microphones
Even LCD backlight
IMEI shown in Settings matches the board, and Samsung Wallet/Knox features where supported

Galaxy M01 motherboard service: frequently asked questions

Will I lose my data if the Galaxy M01 motherboard is replaced?

With a replacement board, yes — storage is part of the board and encrypted to it, so your data can only be restored from a backup (Smart Switch, Samsung Cloud or Google). If you need data from a dead phone with no backup, ask about board-level repair: reviving the original board is the only way to reach it.

Can a dead Galaxy M01 be fixed without replacing the motherboard?

Often, yes. Many no-power faults on the Galaxy M01 come down to one component in the Snapdragon 439 platform's power or charging circuitry, a connector or liquid corrosion. We diagnose first and only suggest a replacement board when component-level repair isn't realistic.

Will my Galaxy M01's IMEI change?

Only if the Galaxy M01 gets a replacement board — the IMEI belongs to the board. Component-level repair on your own board keeps your IMEI. Altering an IMEI is an offence in India and never part of a legitimate repair.

My Galaxy M01 screen is dark but the phone rings. Is it the motherboard?

It can be. The Galaxy M01 has an LCD whose backlight is powered from the board. Shine a torch at the screen: if you can faintly see the image, the LCD works and the backlight circuit (a board-level fault) or the display's own backlight is the likely cause. We test with a known-good display to tell which.

Can the Galaxy M01 be upgraded to 5G with a new board?

No. The Galaxy M01 is a 4G phone; 5G needs different radio hardware that this model doesn't have. A board replacement uses the same 4G design.

My Galaxy M01 stopped working after water damage. Can the board be saved?

Often, if it's looked at quickly. Liquid causes corrosion and shorts on specific parts of the board, and cleaning and replacing those parts can bring a phone back. Don't charge it or keep trying to switch it on.

How much does Galaxy M01 motherboard service cost?

It depends on whether a component-level repair works or a replacement board is needed, and on board availability for your exact variant. You get a quote after diagnosis and before any work, and you pay after the service.

Is Galaxy M01 board work done at my doorstep?

Board-level work needs a microscope and a soldering bench, so it may not be possible at your doorstep. We'll tell you when you book; pickup and delivery are available, or you can bring the phone to our Nampally studio.
