They look much the same, but the chipset is different, so the code is incompatible. Look here for various available downloads for the two models. Thanks @EskeRahn, you are completely correct, I bought a Pro1X and didn't realise the difference. Doh! I got caught up with some other projects and came back to this recently. The phone hadn't been charged in a few months and I definitely broke the partitions by treating it as a Pro1. When plugging in the phone via USB-C the red light flashes on and off, but I can't get any other response via button combination or after leaving it charging for a few hours. Any suggestions for me to reset this device and start again? I'm concerned leaving it uncharged for a few months may have caused some battery problems, or possibly it's failing to start up at all because of what I did to the partition table. I'm building a Windows VM at the moment so I can follow the "Stock Android 11" instructions here: https://community.fxtec.com/topic/3207-various-roms-available-to-the-pro1pro1x-available-for-download-links/ Any help is appreciated, thanks! 1 Quote Link to post Share on other sites

If the phone were turned off, the battery of a phone usually last for at the least a year if fully charged, without depleting it self. But if it was in a state where it turned it self off, and then was left for months, it might well be problematic. I do not know if there are any tricks to charge the battery in that state without opening the phone and charging the battery directly, by a circuitry bypassing the charging-logic (do not give the battery 5V directly). Many phones by default comes with a silly mode active where supplying power lets the phone attempt to boot. That was true for the Pro1, and assume it also goes for Pro1X. This mode is crazy as a phone with a flat battery usually can not be charged!! As the boot power needed is larger than what the phone requests the charger to deliver... If the mode at the least checked the battery level before attempting to boot, it might make sense, but it does not, and is thus somewhere between stupid and crazy!! For anyone else still having their device working I STRONGLY recommend to issue a fastboot command from a PC to fix this, by allowing it to charge while OFF, See e.g. Here ) 2 Quote Link to post Share on other sites

Thanks. I haven't looked at the battery inside, but I do have a IMAX B6 charger, so I'm assuming once I open it up I'll be able to charge it. Teardowns look like it's a 4.4v charging limit with 3200mah capacity, so that should be simple enough to trickle up to a good state. 1 hour ago, EskeRahn said: Many phones by default comes with a silly mode active where supplying power lets the phone attempt to boot.

Whitey 8 Posted April 9, 2023 Author Share Posted April 9, 2023 (edited) Well I was able to get the phone disassembled and get down to the battery! Haven't done that in a few years, good fun! However removing the battery (which felt superglued in!) I see a connector I don't recognise! Does anyone know this connector? I assume the top (top 2?) connectors are positive and bottom (bottom 2?) are negative from the naming convention. However this thing is really tiny, like 1/4 the size of my pinkie fingernail tiny (apparently my iPhones zoom and focus is quite good!). I'm not confident I could hook this up without an adapter, which I suspect I _may_ be able to get if I can find out the correct name for this connector type. EDIT: Sorry, just realised compression made the battery marking illegible. Hopefully the below is helpful to someone else if not me in the future! EDIT 2: Well, browsing around to try and find battery info and I found this: > On another note, as we are also investigating the battery protection issue, we would like to carefully remind you to always ensure there is some level of charge in your Pro1-X - even if you don’t use it. At times, the battery can likely go into a sleep state that would require a jolt to activate again. During this time, your phone will not boot and will not charge. If you’ve encountered this, please get in touch with us at [email protected]. Looks like I'm impacted. I'll flick them an email and work out the next steps I guess!

claude0001 1,315 Posted April 25, 2023 Share Posted April 25, 2023 (edited) So ... I recharged my Pro1-X battery using a laboratory power supply after it had depleted completely, probably due to the "battery protection bug" mentioned by f(x)tec in their updates. It turned out that the most difficult part in this is getting to the battery. The Pro1-X is not nearly as "serviceable" as I expected. Separating the different parts of the body is not as easy as the instructional videos suggest. Also, the battery itself is glued into the phone, which makes its removal a scaring endeavour. Note that removing the battery from the phone is not strictly necessary for re-charging it. In principle, disconnecting from the phone circuitry would be enough. But for me, having the battery detached simplified connecting the external charger. You decide. The charging itself is actually not very difficult, provided you have the necessary equipment and at least some basic electrotechnical skills. Still, here comes the obligatory disclaimer: Mistreating a Li battery can set it on fire and/or release toxic gases, be sure you know what you are doing at all times. The Pro1-X's battery has a more-or-less standard connector featuring two power lines and two sensing wires. For external charging, make sure to connect to the (outer) power lines. The laboratory powersupply I had at hand was a bit oversized for the purpose (32 V x 5 A), so I included two multimeters in the charging circuit as shown in the pictures. Using them, I could monitor the charging current and voltage with greater precision than the PSU's built-in gauges would allow. Especially for the voltage, we are interested in the 1-mV scale. As written above, my battery started with a charge of "0.00 V". I started by slowly raising the charging voltage in voltage controlled mode, taking care that the current never rose beyond 1 A. This way, I quickly reached the 3.7-V operating plateau of the battery. From there, I set the power supply to charge at 840 mA in current-controlled mode for 1.8 h. I figured this should be a quite safe value, as the fast-charger operates at much higher current. Given the battery capacity of 3.2 Ah, I estimated to reach an approximate charge level of 50%, as the Pro1-X would later confirm. During the current-controlled ramp, the charging voltage never exceeded 4.1 V. The battery did not noticeably warm up in the process. At the end of the procedure, the battery voltage (measured with the charging PSU switched off) was approx. 3.9 V. In the end, my Pro1-X booted normally with the re-inserted battery.

Name_not_avail 64 Posted April 25, 2023 Share Posted April 25, 2023 God I hope I never have to do this job. If the LOS devs re-establish the ability of the 1x to charge offline, then hopefully I never will. 1 1 2 Quote Link to post Share on other sites

As @Sean McCreary clarified in the LOS 20 thread, off-mode-charging cannot actually protect you from the battery-depletion-bug. The Pro1X's (and likely any other Android devices's) charging is controlled by the OS in all cases. Seemingly, this means that some minimal amount of battery-charge is always required to boot the OS to the level where power-supply can be actively handed-over to a USB-connected PSU - irrespective of whether only the "charging screen" is loaded, or the full Android/Lineage GUI. Do not ask me why things are designed this insane way. It just seems to be the reality ... Edited May 1, 2023 by claude0001 1 2 Quote Link to post Share on other sites
david 921 Posted June 4, 2023 Share Posted June 4, 2023 I just saw this topic. For anyone who doesn't have the lab equipment, here is how I charged my Pro1 battery outside of the phone. @claude0001 - Any chance you can provide clear photos of the battery connector and the motherboard connector it plugs into? The connector on the Pro1 is the same as a Xiaomi MI 6. We don't yet know whether the Pro1X has the same connector. I can't tell from the photos in this topic. *nervously checks his Pro1X battery percentage* 1 Quote Link to post Share on other sites

Here is the charging board I used for my Pro1 battery, with the Xiaomi MI 6 connector. I *think* the Pro1X connector may be the same as an OPPO R17. Here a close-up of both the motherboard end and battery end of the OPPO R17 connector: It looks similar to what @Whitey shows in his photo. Without being able to compare the actual sizes, we can't be sure. My educated guess says it is probably a match though. 2 Quote Link to post Share on other sites

They both have the same arrangement of Dash-Dot-Dot-Dash, for the connector contacts, on the battery cable end, but the dashes seem longer for the OPPO R17 than what is shown in @Whitey's photo. It may still work, but I'm wondering if there is another, similar connector, with the dashes being shorter. If anyone wants to send me a Pro1X battery, I'd be happy to figure it out.

Foop 5 Posted July 10, 2023 Share Posted July 10, 2023 I mothballed my Pro1x but am traveling internationally tomorrow, so I wanted to bring an unlocked phone. Pro1x red LED will light for about a second, then turn off. USB ammeter shows 0.1-0.2 amp draw while the LED is on, then back to zero. No screen activity. Is there a way to force it to take a charge, besides opening the phone up, and hooking the battery directly to my bench-top supply? Quote Link to post Share on other sites
