So, it appears that I was able to repair my Pro1-X's radios. Previously, telephony and mobile data wouldn't work for me, as documented earlier in this thread. WiFi, Bluetooth and GPS had always worked perfectly. It turned out that my Pro1X was missing most of its "antenna" connector springs. My main antenna (aka. USB) board was missing two of its three connectors, and the last one broke off while I was diagnosing the problem. See picture attached. It appears these things are really fragile. Also my "diversity" antenna board was missing one connector, which I found rattling in a

It's hard to say whether these antenna connectors were broken when shipped, or due to disassembly on your part. Have you've heard the antenna rattle inside the phone when you first received it? Would that be the reason why you took apart your device to check? The antenna springs are indeed fragile. Not like other devices we see in the market, they normally have antenna pins pointing upwards, not sideways that contacts the frame. This can be especially seen in devices that have metal enclosures. The antenna springs on the Pro1-X are surface mounted via SMT, and the glue is to fix it in

You are right we should not jump to the conclusion but it certinly sounds like a reasonable explanation why it is working for some and not for others. And on this one I wonder what havoc that could make, depending on where it 'lands'?. It does not have to be a 0 to 3.8V short circuit to cause trouble, could be 'anywhere' exposed.

Hey F(x)tec Community! I haven't been here for a while as I was busy with other project and stuffs. Recently I just came back to work on mainline Linux kernel for F(x)tec Pro1X and I'll be using this thread to update everyone on the progress. Currently only GPIO expander, touchscreen, USB, buttons and flip sensor. Everything else is not configured or doesn't work yet. I attached dmesg for everyone to see. bootlog_11282023.txt

No, I think you got me wrong. No offence but, like many, you do not seem to understand what "Linux" really is. Do not worry, you are not alone in this. Especially people with many years of experience in running Linux on x32/64 servers or workstations often make wrong assumptions when it comes to embedded systems, like phones. Android does use a real Linux kernel, and thus is a true Linux system. You can grab its kernel source from kernel.org, configure it to you liking and create your own custom ROMs based on it. The only limitation is that you practically can only run the single major ke

And if it turned up in time for Xmas you could call it your 'Pro-Ho-Ho-1X'

What an interesting turn of events. Way to go, @claude0001 If this is indeed the solution, there is absolutely no way I could do it myself. I couldn't solder two telephone wires together, let alone parts/wires of a circuit board, etc. I SUPPOSE that fxtec might take on the repair as warranty work, if only because said work would produce a phone (the original idea) rather than a pda/hpc that many folks are currently sentenced to.

This sounds like a very important find. I marked your post as recommended, and would love to hear some official comment on this. @Casey perhaps? At the least that could explain why some sees this issue and some not, as it thus seems to be related to specimens, and errors in assembly (and QC).

in precisely 1 month i wil commemorate my 3 year order status . it wil be a special day

unbelievable ! you did it ! Fxtec lack engineers like you. If my pro1x ever comes one day.... ...but however thank you ! 🙂

I wasn't able to 100% confirm that all units shipped out from the previous warehouse were working. Given the timeframe I had, it was quite impossible to check them one by one... Though, I understand your concerns and will reach out to those who did unfortunately receive a depleted Pro1-X and to offer support whenever we can.

I'm very sorry to see that you received a depleted Pro1-X. If you'd like to carry out this repair by yourself, there are currently two ways to do this, but both would require you to disassemble your phone. We do not recommend doing this unless you have experience with electronics repair. As others stated, some components are very delicate and can be prone to break if not careful. If you do wish to proceed by yourself, we have a detailed video tutorial on how to "jump start" your battery by taking apart your Pro1-X. A link of the video can be found here. You can either prepare a cha

You'll have to solder the old circuit to the new battery. Shouldn't be too hard to do, just make sure to be quick so you don't overheat the battery. Active cooling is an option if you are worrying. There are some laptop batteries that break once their circuits are disconnected from the battery cells so you have to simulate the voltage while soldering. But I would be very surprised if that'd be the case here as well. I've ordered a few units as well and as I have a broken battery here, I'll be happy to try the first time. Also, kudos to @Tomatoman29 and @CornholioGSM who brought us tha

Correct battery (without electronic) can be purchased on taobao....but is not simple to order it. https://parcelup.com/shop/item.php?id=664752226102

Let's not jump to conclusions prematurely. I had opened the Pro1-X multiple times, so I cannot exclude that I broke these contacts off myself. One I definitely did, as noted above. That's also the reason why I did not try to make a warranty claim out of this. Then again, two of the connectors seem to really have disappeared, so maybe they were missing from the start indeed. For sure the Pro1-X had its connection issues since the first time I put a SIM in it. Lets see if others affected by the issue find the courage to open their devices, and discover similar problems. Indeed,

Well I got my shipment email. Looks like my pro1x will be shipping out soon. Tracking from usps says waiting on package. I was an indegogo backer from November of 2020. Hopefully it gets here aoon.

I'm testing it for like a week or so on my Pro1 and at the moment that's the best android based OS I ever used. Even banking apps are working with microG. Later after changing my server I will host my own cloud for synchro.

Love my Pro1. Hubby uses a Bluetooth keyboard to type on his phone.

Hi @Casey. Thanks for your thoughts on this problem. Indeed, as I tried to make clear above, I cannot really exclude I did break the antenna contacts myself. One I certainly did. No, I did not track this down because I heard something rattling inside the phone. I had previously opened the Pro1X's main body several times in the context of the battery depletion bug I had experienced, and because of the right-speaker-noise-at-full-charge issue. At that time, I did not pay much attention to the state of the contact springs (I did not even know what their purpose was). Though I do not rem

Wow... I suspected something like this. I'm not sure why there's glue for those contacts on the board, but they should be soldered as well. To me this means soldering wasn't great (or non existent!) to begin with and will induce all sorts of noise for cellular and wifi signal inside the phone to begin with. This will definitely cause all sort of connectivity issues and explains why some was never able to use it properly with their provider or wifi and others could.

I missed to celebrate the 4th anniversary in September...

@claude0001 👍 Fully agree!

The one workaround I've found for my old Pro1 with LineageOS which has the same problem is to use the 'Rotation Control Pro' app which I already had installed anyway. I disabled 'per app settings' and now I manually switch between portrait and landscape with the app's controls.

@MonCon I've experienced a "battery depletion event" once with the Prawn-X. As documented here: The battery voltage, as measured with an external voltmeter, was "0.000 V" indeed. So booting into whatever runlevel of Android would not have been physically possible any more. In that situation, the only way forward is to charge the battery using some external power supply, as documented in my post above. I guess this is also what F(x)tec are doing if you send in your device for repair.

Contrary to popular belief, that setting cannot protect you from the battery depletion bug. As @Sean McCreary clarified in some other thread, Android devices are not really "off" during "off-mode-charging". The charging screen is just a different runlevel of the operating system. The bottom line is that the Pro1X's Linux kernel has to be up and running in order to actively switch the power source from the battery to the USB charger. That won't happen "on its own". So also with off-mode-charging enabled, there has to be enough remaining battery juice for an initial boot of the OS, oth

The good news is, the warranty repair is just dealing with London, not HK, and there is no need for parts to be ordered, so it should be a fairly quick turn around once you get the support ticket set up with them and they receive the unit. I've had two warranty repair episodes with them and both went well. They are not quick with communication, but they will get the job done. @Casey

Please don't disassemble new and intact phones if you don't have to. The Pro1 is easier to disassemble than other phones and it has a lot of potential for modifications (like I have two USB C ports) but it's not worth the risk damaging some components while opening it up. I know it's sad but please let it get fixed by FxTec, even if it takes some (more) time.

I see, you don't understand how those batteries are labeled. 5036108, model taken out of the fxtec battery is in reality size of that battery. 50 means it's 5.0 mm thick. 36 means 36 mm width 108 means 108 mm length That's why I found this battery, it meets all the size criteria and that's why it has very similar but not the same capacity. Those keyboards has 1450-1450 mAh batteries because they are twice as thin than the fxtec battery. And that's why you are wrong, sorry. Why there is no 3200-3150 mAh batteries in this size on the market? Because batteries with tha

Ah of course X-mas, so that is what the X stands for.

In the video he says the red is negative and the black is positive. I thought it was the opposite (although I very well could be mistaken). Is it different in different countries?

My Pro1 X just arrived about half an hour ago. Luckily, my device doesn't have a depleted battery, but it came out of the box at around 10 to 15 percent. I'm guessing some units were close to dying when F(x)tec checked them, and they fully ran out during transit.

Glad you finally got it, but sad that it is in a useless state... Well the only known remedy is to disassemble it and charge the battery directly with a suitable circuitry. That is what FxTec is doing with returned units. So sad that the road from production to delivery has been so long that this happens to several... So the only options I see is to return it/them to get fixed, or to disassemble it and charge. Rather than some fancy circuitry I have seen some suggest to use three 1.5A batteries coupled, as they have a limited power and thus are unlikely to damage the battery.

These issues seem to be *mostly* solved with latest updates - I've been trying for 2 days now to replicate the random C2D issues and so far have been unable to replicate it anymore. I was able to pull a crash log from android shortly after it happened again about 10 days ago. I don't know in what way it would be useful, but it's there at least. Now I just need to figure out how to properly get SafetyNet stuff configured so I can try migrating again. I tried ih8sn but that seems to be unsuccessful.

That's the point. There is no chance to find a ready plug-and-play battery outside of fxtec. We can only find a close enough size and transfer the BMS with cable to another cell. https://vi.aliexpress.com/item/1005002957619888.html 2000mAh battery which will be 100% fitting into the Pro1. Always something...

He'd certainly be busy 🙂

It was probably a mistake and meant to be sorted out... Maybe they should hire a repairman in the US for repairs over there?

I've merged your post with a thread that discusses the issues you raise. I hope it will be helpful, though it doesn't get your refund. This is a user-to-user forum that people at FxTec like @Casey sometimes check in on, but not with predictable frequency, so no one here can provide an answer about the refund itself. I hope calling out to Casey helps.

Are there Pro1X with the shifted keyboard? I thought all the Xs are shift (Expect the X-mas units, which where blue Pro1s).

I'm not able to tell the difference from the images for sure. I THINK the globe on the space bar is placed a little above the centre line for the original Pro1, and is centred on the Pro1X. It is usually easier spotted from the usb-end, as the usb sits a tad further from the back on the Pro1X (the centre of the plug almost align with the bottom respectively top row of the speaker holes) But yes there are some black Pro1X too, and indeed this one looks pristine from the photos, my Pro1 certainly doesn't look like that any more after four years of wear....

Hiya folks So, I've got a Pro1X with all of the Pro1X issues that I wish to sell. The box has been opened but the device is in near mint condition with a custom book style case that I made for it. Anyone have any idea what the current going rate is for one of these? Will follow with pictures shortly. Thanks Andy

As you got it open, I strongly recommend to charge it, as it causes a lot of trouble if it depletes....

Just got it in the mail last week. The shipping box was sealed but the Pro1 box was not sealed when i received it. I did hit the power button and it did power up and ask me to select a language. I did nothing I just powered it back off. If your interested let me know. thanks Jason to be clear I have not used it all all other then tuning it on and then right back off when I saw it powered on. I can take payment through Paypal and venmo. Any questions let me know. my email is [email protected]

In my experience, generally red is +ve and black is -ve. I'd check the polarity with a voltmeter before connecting them.

A little foot note I'm not quite sure where to put. Just noticed on a Pro1X (not Pro1), when in OFF state pressing the power/button briefly, will have the led blink briefly, green if full, I do not know if it will use other colours in a lower state. So if a Pro1X will not boot, this might be helpful in telling whether it is a depleted battery or something else....
