Now, the USB-C port works well, but the phone struggles to get a mobile network connection. Indoors, both manual and automatic network selection fail (automatic: "emergency calls only", manual "Couldn't connect"). Outdoors, I get a 4G LTE connection, but bandwidth and jitter are poor, and I get 0dB SNR reported by the Network Survey app.

My guess is that there's a problem with the antenna cables.

Things I have tried so far:

• Reseating both ends of the coax antenna cables (white and black)
• Inspecting the cables, the PCBs, and the antenna cable connectors for damage
• Changing network mode to "NR/LTE/GSM/WCDMA"
• Reverting to the original sub board, to try to rule out a problem with the new board

Does anyone have any suggestions what else I could try?

This is the replacement part I used: https://www.ebay.com/itm/285156938467

And this is the guide I was following for disassembly and reassembly: https://www.youtube.com/watch?v=Ue6e6FOL...

One thing I noticed is that the replacement board is slightly different to the original – there's an additional antenna port on it (labelled "L8"), and there's seemingly a microcontroller missing vs the original. Is it possible that there are different hardware revisions here?

Does anyone know what component this is? (Blue/White)

Just generally and not its exact value

I've been looking around on Ebay and Amazon and screens for this thing are actually almost as expensive as the whole used phone. I can get a whole used phone for $75 on ebay and I can buy a guaranteed fit screen for $45 on ebay. Is there another place I should be looking for a better price on an LCD display with a frame, or should I just buy another phone and transplant the screen and frame? I don't want to lose out on all the embedded data and login information in my phone, or else I would just migrate to a new phone without looking back.

Buying a whole phone also would let me replace the back glass cover without needing to buy another part.

Or is it easier to transplant the internal components that make my phone mine into a new phone and discard most of my current device?

• when just charging it lights for 7s and turn of for a second.
• when trying to go into boot (volume down and power before putting charger) it does other pattern: 3s on, pause, 3s on, pause, 7s on.
• without battery and connected to charger - blink of light (but weaker), pause, 7s of light

*

Phone was pretty low on power before my attempt of destroying it and it took me some time to work with it (screen came cracked, waited 2 days for replacement) so maybe battery doesn't have any power.

I tried to charge it through night, tried charge it with PC USB, no dice.

Help?

I had unlocked the Bootloader of my moto phone to root it, and I did it but after several days I want to unroot it so I went to fastboot and locked the bootloader without flashing the boot image, now i can not turn the phone on to normal, it only opens in fastboot mode. I later flashed boot image but it doesn't work.

Kindly help me to repair my phone.

Thanks
