On March/2024 I brought MT3000, after a Firmware Update, lost LAN port connection and after that nothing but problems. I tried a Factory Rest but I did something wrong. Last time I saw LED indications were,
[- plug in power code - led brink 2 times - solid blue light about 3 minutes - fast brining few minutes - then light is turned off by itself]. I was expecting a Rebooting Process is taking next, I left power ON couple of hours but nothing is happened. I disconnect power, reconnect power few times but no responses. Maybe it got deleted all or maybe Bootloader?
Then I saw talking about UART connection on this forum site. Can I connect UART to serial port and install U-boot file them Firmware file? And how, I just download "putty.log" first time. What will do you see from this log. Please instruct me. I am new to this but I will learn.
putty.zip (816 Bytes)
Have you tried this?
Yes, I did twice them what happened as 1st post. It is no longer works with U-boot procedures. Then I found UART to Serial connection, I followed what I saw to down load 1st "putty.log" and listed on my post. I don’t know how interpret the “Putty .log” I don't know Putty's command to go farther, That is all what I can do for now. Can I write U-Boot file on flash memory? Can you teach me how?
Not sure it makes too much difference, but you are likely using 4.x code, so try this one instead:
No, neither method of 3.x code nor 4.x code did not work, instead I used Advanced Uboot - GL.iNet Router Docs 3 straight into Serial Port (Vcc, Rx, Tx, Gnd) use UART adapter with Putty software. However what I saw my Putty screen was quaint different form on the Web site picture.
OK, Even how badly erased memory, when you press and hold Reset Button and apply the DC power will the LED is start blinking? My Mt3000 don't do.
And I notice that before damaged it, leave MT3000 little while and came buck, That is turned off by its self, and won't come back ON unplugged power and plugged in. and few days later its start booting process. It is very strange machine.
My Putty.log is this

==============================================
I don't get any messages after this.
My CPU is MT78818 instead of MT7918.
Can I install u-boot file?
USB to Serial port, I got Putty log this far and it is not respond my typing, TFTP connection dose not respond from MT3000 LAN port.
Is CH341 programmer work? Which IC is target on? U2645?
Sorry I wrought wrong IC. yah, it is MT7981BA.
And I am asking again, (openwart-mt3000-4.6.4-0904-1725421504.img) can be writing on flash using Ch341a Programmer?
@alzhao do you have a idea how this being done?
Sorry for the trouble. But I suggest you contact support and get a replacement.
I cannot interpret the putty log.
@alzhao I already talked to a support team but they cannot replaced it, because I bought from Aliexpress unsupported store.
I saw the forum page ("System halt!" message at the booting of MT3000) it is very similar to my problem and he fixed with CH341 Programmer, I believe.
And I just want try if I can or may be using this u-Link NT (.u-Link NT.)
You can ask the 3rd-party seller to replace it. Aliexpress may help on that.
Yes, the name itself sound like genuine store but 3-party store is 3-party store, it is long gone for only 2 weeks of warranty.
Buy the way "GL.iNet Official Store5100113"at Aliexpress is GL.iNet represented store, I fund later and also GL-iNet support team say so.
I am now start working on this broken unit to revive it and beginning to understand a programming process slowly.
I mean, you can ask Aliexpress to step in and get warranty. There is no way for 2-week warranty only anywhere.
please do not mix up " GL.iNet Official Store#5100113" as bad guy, I bought from different store and it was on May/2024. this is similar story as mine (Beryl AX (GL-MT3000) stuck in boot loop?)
I already open the unit and gathering informations for Programming, and this is very informative subject.("System halt!" message at the booting of MT3000)
thank you
Are you able to follow that guide and get it working? Pls let me know.
