    OnePlus 6 A6003 No Service

    Hi everyone, I'll start saying that I am a beginner in microsoldering, I am still learning. Recently I am trying to repair my OnePlus A6003 with a problem of having no service. The phone dropped very hard while riding my bycicle. The screen on the area of the sim card is broken and after that the phone started to have problems with Internet data, very bad reception. So i checked for shorts and it seems there were none. I opened the phone and checked the area of antennas helping me with ZXW. Unfortunately I couldn't find any schematic for my model. Then I saw the area in the picture: the red square chip seemed a bit lifted so i tried to remove it in order to place it better but I ended up just breaking it, now I have no signl at all, but I can still connect to wlan without problem.
    The phone is fine what is missing I believe is only that chip but I have no idea what kind of chip and were to find it. It is really not convenient to buy a broken oneplus only for a chip.
    If anyone can help me at least to identify the chip would be great.
    Thanks

    Believe this is Qualcom p/n QAT3514 and is a RF switch / multiplexer.

        ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
        by DynaxSC
        Hi

        I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
        The SPI chip is an Winbond 25Q256JWEQ model (1V8).
        The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
        The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

        I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

        Help with trying to fix phone that is not charging (Pics inside)
        by SluggerB
        I have two TCL A30 phones.

        Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

        New Phone: Works fine, bought as a donor board to try and repair Old Phone

        My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

        Asus Chromebox CN62 - wrong chip put on BIOS reader
        by BMCappelletti
        Long story short:
        - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
        - gave the computer to his son a couple years later
        - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
        - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
        (seems like the story was not that short)

        He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
