Hello,
My Poco X3 Pro is stuck in the boot loop, after a lot of trying the "soft" flashing and failing, I have ended up trying shorting the test points.
The test points for this device are under the MB flex cable, so there is no way this can be done without disconnecting that cable.
I have few questions. answer to any of these is much appreciated :
I have installed Qualcomm 9008 drivers (Both installer and manual methods) , but no "Ports ( COM & LPT)" Entry appears into my Device Manager, What could be the problem ? or it would only appear when the phone is connected through EDL Mode ?
Would the device enter the EDL mode while that SUB MB cable is disconnected ?
and does it matter on what stage the boot procedure is currently running when I do the shorting and USB insertion (as I mentioned, the device is continuously rebooting when it first reaches the POCO logo) ?
You'll only see the Port when the device is present. If you click View > Show hidden devices in devmgmt.msc it will show devices that were ever connected.
Dunno. Is that cable for the USB? It's problematical because the Sahara bootloader in ROM is very brittle and can't tolerate USB cables disconnecting/connecting.
If your device goes through a full reset for whatever reason and the test points are connected it will go into EDL mode.
Thank you very much for all the answers!
Regarding #2:
Here I attach the picture of the ribbon cable I asked about:

As shown, It has to be disconnected while in order to be able to short the points lies under, just by the cable's connector.

im facing same problem, please help me
How you resolve the problem?
@AssemJo Sorry, I didn't notice your response.
(It's often good to quote a line from somebody's message so that they get a poke.)
It looks like that main FPC would include the USB connector.
I wouldn't be surprised if some of those test points are the USB 2.0 D+ and D-.
In the factory they would use the USB TPs and the EDL TPs to program this without the main FPC connected.
Your choice is to tape (or solder) tiny (30 AWG, 0.05 mm²) wires to the test points so that you can access them while the FPC is connected.
In other cases where this is room I've permanently installed a magnetic reed switch.

I may be doing something wrong... I'm following the steps on this thread but after Treo enters the boot loader I'm not able to establish a ActiveSync connection between my computer (Windows 7) and Treo.
The only thing that appears as remotely related to Treo is the "Qualcomm CDMA Technologies MSM" that is connected to "Microsoft USB Sync", as shown in the images below.

And I find weird as it reports Qualcomm CDMA Technologies even though I have a GSM phone.
Can anyone point me in the right direction?
go to settings - connections - usb2pc and disable fast data sync (or advanced data transfer)
and reconnect the phone
try this

is it same problem as above ?
No I don't think it's related with the other errors and disabling Advanced Data Transfer didn't help either.
I just want to know if I'm in the right path.
I have exactly the same problems...
I've managed to install CMONEX HardSPL
I've successfully managed to install CMONEX HardSPL.
The steps on the cmonex's original post are correct, however it fails to mention that you will not be able to establish an ActiveSync connection, but the "Qualcomm CDMA Technologies MSM" connected to "Microsoft USB Sync" in, in fact, what you should wait for.
The installation on my Treo was successful as the pictures below can attest.
Managed to flash Hard SPL
Just relax!! You should wait till your computer find the driver for Qualcomm CDMA at windows download center (so you should have a live internet connection at the time) it will take a while, but after that, you can flash the SPL without any problem.
If your operation system fail to find the driver, just delete the ?Unknown device from control panel->system->devices and reconnect the usb cabel, after that check if it search for the driver. that's it.
No It wont
I have the same problem Palm Treo pro and even after the CDMA driver loads I still get a communications error I have done every thing I can think of to get it to work but it will not
Directly after phone goes into bootloader mode (tri-color screen), unplug sync cable and immediately plug it back in. Do this before you start clicking thru the Rom Update Utility menus..
Does anyone know ANYONE that knows another spot on the Circuit board that I can pick up USB at? My issues is that the micro usb port was damaged. The pads ripped off the pcb and most of the traces. I tried removing the enamel from the PCB to get a solder point for data + and data - but to no avail. If anyone can explain or show me pictures where else on the board I might be able to get the 4 USB points at I would be ever grateful. I'm boot looped AOPK 29, can't get into clockwork recovery mode. Download mode works..but the PC doesn't even see the phone(not at all..not a driver issues 100% sure). If I can get the USB running..I can flash it back to operating condition. At that point I can manage to solder on a new micro usb port and get to the +5v and -5v so I can charge the thing. As I mentioned before its the + and - data signal I can't get. So even if you can point out where to get a hold of those that would fix me too. I can solder pretty small.
Or anyone forum where you have a feeling someone might have an answer or would be kind enough to look at a high res picture of the PCB and help me trace it. I love my mesmerize to death. I'd really hate to see it die like this..It might be "legacy" But it'll post over 2500 quadrant and runs fast and smooth.
Thanks in advance.

Hi everybody,
I‘m afraid my HTC One S has now completely broken down.
The last years I had a few times the problem, that the phone would not start. Only after opening the phone and disconnecting and reconnecting the battery the phone was able to start again.
However in the last week the phone shut itself down about 5 times.
Two days ago this happened during a phone call. There was a continuous tone for about 30 seconds while the display was black.
Now it won’t start no matter what.
I’ve tried already:
holding power button (for a short and long time),
holding power and volume down button,
disconnected battery,
nothing, there is no flickering of the display, no status LED, no vibration…
However when I connect the phone to a power supply the LED lights orange and it still wont start!
So I tried to connect the phone to the PC: When I press the power button, after 4 seconds I can hear the windows sound "USB device recognized" and if I don’t release the button the sound pops up every second.

So the PC somehow recognizes the phone?
Is there a software or any other way tho start the phone again or at least can I somehow access my data?
Thank you very much for any kind of input!!!

The first thing you should do is check the voltage of the battery, or otherwise the amperage, if all is well, you should go to the Stock Roms
http://www.androidruu.com/index.php?developer=Ville
don´t forget tell´us
Assuming you're still looking to fix your phone, assuming your battery is fine, your eMMC may be going bad, and fastboot/modem/bootloader certainly could be corrupt. Good thing someone recently uploaded the magic hex to the One S. Once I can snag some files from the RUUs, I think it's possible to revive both your and my dead One S.
I was trying to put the first rom of the gear fit 2 pro 365 with odin but I accidentally added a rom of gear fit 2 360 and now it stayed on a black screen that says "Download has been failed. Please retry wireless download” but I don't know how to return to the wireless donwload screen because they don't let me the buttons
You managed allready your problem?
https://www.youtube.com/watch?v=gifgSLLIGRY
In theory Power Button should work for "hard reboot"... to leave nearly every screen... hold few seconds in "emergency situation"...
If you killed Downlaod wireless option... but Downlaod aka Odin Mode work... you need USB cable...
Somewhere I saw Pinout... forgotten where...
Best Regards
Edit 1.
Only if USB cable... or other Hardware replacment attempts... how to open SM-R360
https://www.youtube.com/watch?v=7eOkpkVtwSw
IMHO SM-R365 not much differ... remove 4 screws... carefully
If I will find Pinout of USB I will post....

I have a similar problem and cant find the USB pinout for the SM-R365
I will try to find...
I can only remember User posted Photo...
Need some time to find this...
Otherwise maybe in Service Manuals PINOUT readable...
If found, I will post somewhere here:
https://forum.xda-developers.com/smartwatch/gear-s3/sm-r765f-teardown-t3659431
Best Regards
I have a Gear Fit 2 Pro R360 that is stuck in download mode, so probably a direct USB connection to a PC running Odin should solve the problem.
Found the service manual with pinout, but I'm not sure what need to be connected.
Do I need to connect the TX/RX through a USB to serial adapter, or the USB_D and USB_D+ directly to USB, or maybe both?
In the service manual there is a special cradle being used that connects to all 5 pins plus 5V+ and GND.

Friend brought an iPhone 13 Pro Max Clone which was stuck on logo, tried Factory Reset through Recovery but it did not help. After i looked for a firmware and found just one that was free and tried to flash it with preloader and it did not pass. Now it won't boot into Android i suppose the preloader is bricked. Pc detects it but i can not find another firmware. I have just a screenshot of the settings menu from when it was working and a photo of the motherboard. If somenone can help me i would be gratefull.

it would be labeled kcolo, colo, etc, on the board (either side) you short it to gnd to get into bootrom mode for flashing
what are the actual specifications of the phone (since in settings it is faked)

I can not identify those test pointa on the board. There are pins on one side of the board but are unnamed.
At the moment the pc detects the phone as "Mediatek usb port" with and without battery and everything i get as device info is in EFT DONGLE. Until yesterday it detect it as "Mediatek preloader" and i was able to flash firmware now i can not. I know it is a MTK6580 chipset 16GB nand.

i don't recommend this, but you can try shorting various testpoints to ground (using a 1k ohm resistor so nothing happens if you do things like short vcc to gnd)
check out mtkclient on github
also you can use any metal heatsink, chassis as gnd
if you check continuity with the heatsink to various testpoints you can find the gnd testpoint
i guess you can solder a magnetic reed switch from the gnd testpoint to kcolo or whatever
so then when you hold a magnet near it it will enter bootrom mode
