Is it a specific name of a chip? Is it contact points on the board? What exactly are we trying to find??Can’t really spot it. Google is not helping me neither. But it should be there somewhere.
Read this https://www.xjtag.com/about-jtag/what-is-jtag/Is it a specific name of a chip? Is it contact points on the board? What exactly are we trying to find??
Ok I will ,,thanks
All of this is on a completely different level of knowledge and expertise, when I read the article's,,, it does not compute,I did find this https://logi.wiki/index.php/Google_Pixel_Diode_Mode_Measurements but somehow no signs of JTAG.
Have not tried it myself. I'm still waiting on the phone with this software. The think is we also want to dump the ROM.Have you tried using pixelrepair.withgoogle.com to try reinstalling original rom on locked bootloaders?
Is that flux on the chip? I would not expect to see flux on a oem device with no modifications.
I do not know, whatever it is,, it was on there when I was pulling the cover guards off, maybe some kind of coating after they install the chips and weldsIs that flux on the chip? I would not expect to see flux on a oem device with no modifications.

Is it goopy almost like thick syrup? Flux is used to clean the solder joints before soldering a new chip. Makes me wonder if they just soldered on a new emmc with the FBI os on it.I do not know, whatever it is,, it was on there when I was pulling the cover guards off, maybe some kind of coating after they install the chips and welds
I actually put it all back together already and am using the mb in this phone testing it, I really don't recall it being goopy rather a hard transparent coatingIs it goopy almost like thick syrup?

You know what ,,,I did not put that one back in I am actually waiting for a power switch but I rechecked the board and when I pulled the cover off again all that wetness was gone , there must have been condensation from something else ,, I get these damaged then rebuild them so my thinking is water got in at some point,, good eye!!Is it goopy almost like thick syrup?

I'm wondering how you got this device. Please watch this youtube video to learn more.I recently purchased a used Pixel 4a, and I now understand why the seller was offering such good price for it and why he refused to respond to me now I have it. This phone has ArcanseOS 10 installed, which has only 3 apps installed... Setting, Clock and Calculator. There is no Play Store app, no Phone app, nothing.
The only useful reference to ArcaneOS I can find in the Googleverse is this one... https://translate.google.com.au/tra...rueck-flashen.973774.html&prev=search&pto=aue where the OP describes his troubles with a Pixel 3. Through the rough translation, I see similar issues... can't enable developer mode, can't unlock bootloader, can't sideload apps.
Some random observations about this phone/OS...
- The phone is in good condition. I used the supplied pin code to unlock it and did a factory reset. Have done basic config with my Google Account, etc.
- In Settings > About Phone - the build number is not shown. I cannot tap on the build number 7 times to enable Developer Mode. I have tried tapping everything in About Phone 7+ times, but I have not been able to enable Developer Mode.
- When the phone powers on, the first thing shown is a message like "Your device is loading a differennt operating system".
- The installed OS is ArcaneOS 10. The system updater says that ArcaneOS 11 is available for download (but I don't want to do that in case it makes this thing even harder to fix).
- I tried sideloading open_gapps and a random developer shortcut app I found, but I can't seem to get them to load.
I'm no expert at this, so I've tried various commands that I found and got some of these results...
(note: some details, esp path names, have been edit for brevity)

Any suggestions on how to unlock this device? Then I can flash it and restore it back to stock.
Thanks
PS. Please do not say "tap build number 7 times to enable Developer Mode/options". If you believe this is the solution, please re-read this post, and the linked/German post, then describe a different way of doing that task that doesn't rely on the build number being visible.
Me again, I actually don't know what that is,, its not condensation,, its some type of substance that can be wipedYou know what ,,,I did not put that one back in I am actually waiting for a power switch but I rechecked the board and when I pulled the cover off again all that wetness was gone , there must have been condensation from something else ,, I get these damaged then rebuild them so my thinking is water got in at some point,, good eye!!
You can get them of you look on Ebay or other websites.How did you get ahold of an FBI Device?
