I messaged Paul earlier about it, and he included a vid showing how to do it. I'd suggest doing so if you need a new battery

I remember there being a video on YT, but I'd have to find it. I remember the details that were discussed about it years ago - that that most annoying part is the glass back and having to remove it and put it back evenly to avoid it cracking. The battery's expansion has made the removal part...

If you don't mind me asking, where do you purchase your batteries from? Mine has started to swell, and I'm sure it's out of warranty by this point

How are you updating firmware? Are you using the factory batch tool? I had the same problem too and was able to fix it through the batch tool. If you look for my name on this thread, you can find my "adventures"

I've just tried to do so now. Is this a shortcut to change screen brightness? It looks like the brightness is changing, but the screen itself just displays black. I've also tried to do a restore through the batch tool to no avail

I've also had this happen before a few times as well. After it erased everything, I did my first upgrade then had a boot looping issue. If you go back a few pages, you'll see my posts about that too

Has anyone else had this problem so persistently? My screen stays black and I can't see anything, but the blacklight and the touchscreen itself still works. I've updated the firmware through the factory tool, but the problem still remains. To be honest, I've also forgotten the complete layout of...

Thanks! It did seem to help! I switched cables and used a usb 2.0 port directly connected to the motherboard, and the upgrade worked this time! I feel like you understand this DAPs and tools better than any tech support! I didn't want to return the DX120, and you saved me from a lot of headache...

Thanks! I didn't realize that the loader could be that sensitive. I'll try both another port and another cable. I do have a very short cable I could use, but the port I used was soldered on to the motherboard. I can try the other one though. I have only used usb 3.0 ports with the DX120. Would a...

The below are from the log when I try to update the firmware. The cable and usb ports should be fine since I've used them to transfer music before the whole boot looping issue began. If the issue is with the device's flash, can anything be done? 22:33:12 026 Factory Tool v1.3.9.0 start run...

Thanks! I found that I had to also reopen the FactoryTool in order to have the DX120 be recognized as a loader and the light to turn green. The only issue I'm having now is that upgrades keep failing. What would make an upgrade fail while using the FactoryTool? I don't think I've ever had one...

I don't think it's possible to connect to the pc in the mode that the Batch Tool needs with the power on. I've tried to connect in 2 different ways- with the power off and with the power off holding the vol+ button. Because of the boot looping, I can't enter card reader mode nor can I connect...

Thanks, but the DX120 freezes any time I try to connect to a computer. I have the Factory tool since I used it before for my DX80, but I haven't been able to use it now because of that. In trying to update any firmware, I did notice that one of the messages says that it is missing the trust.img...

So no one has had this issue? Should I just return the DX120 then if this problem can't be fixed?

That's what I mean by updating through the device. Using the recovery menu
