PLEASE HELP_ HPiPAQ hx2795-WM5

Hi Guys.
It might seem funny. I do not have a PDAphone but I have a problem with my HPiPAQ hx2795. And I would greatly appreciate any comments or tips.
Here is the story:
I was trying to update setup/ROM. the first three updates went well. The forth one, didn't go through; it was showing time-out. it happened twice, the third time, I noticed a message on the left lower corner of the device,saying Connect A/C to flash, I tried to do it quickly before getting time-out. I guess I didn't do it quick enough. Anyway I plugged in the power to the cradle and it started flashing the ROM then I got the time-out error again. The screen reset and stuck @100% not going any further. To make it worse to me, it was not detectable by MS ActiveSync at all. I tried the active chat with the tech support of HP they said all is left for me to do is "going to parrot mode (= USB /serial Mode) and if the OS is not corrupted then I can repeat the ROM update and fix it" which I did with no luck as even in parrot mode, the device would noticed that the USB is connected but the PC would NOT recognize the device.
While I was searching the internet, I came across your site, beautiful and very interesting. I saw some people is using a program called NVID.exe.
IS THERE ANY SOFTWARE LIKE NVID.EXE THAT I CAN USE IT TO SOLVE MY PROBLEM on this HPiPAQ.
I was wondering about using something like that to get the device detectable by PC again. Is is possible even theoretically?
Please HELP.
I greatly appreciate all your comments and tips in advance.

Did you tried to do a clean reset? Or to put the device in bootloader or white bootloader mode and try to connect and see if recognize it?
Hard reset: butons 1+4+reset
Clean reset: buttons 1+3+power+reset
White bootloader mode: buttons 2+4+reset

what you call it "white bootloader mode" they call it "parrot mode". and yes I did try that. In that mode it shows Pre-BL: 1.00.04 that shows USB is connected or USB Cable is removed; however; my Win XP cannot recognize the new USB device.
Is there any way to make PC recognize this "HPiPAQ hx2795 in Parrot Mode". I mean any driver for WinXP to recognize this USB device as reachable device (updatable ROM)? Maybe that could be the "MAGIC KEY" to solve all people's problem suffering from such an issue?
I hear about mytt11.exe alot in posts here and there. What does it do? Where can I find it in order to give it a try?

Please anyone can help me ???? tnks.
Sory for my english.

Are you running stock or a custom ROM? I haven't had that issue(yet) but I am trying to help troubleshoot.

viBranZeOS-2.0-WWE this is the rom that i'm using. and i try alredy 2 other roms, and its the same.

I honestly have no idea what the issue is nor a fix/work-around. However, what I am attempting to deduce is if you had a stock ROM I wouldn't be of much assistance because I only run the ROM in my sig/signature, which is a custom ROM. Now, I'm not 100% on if your ROM has this option but I know the ROM in my sig has an option to change the behavior of the USB connection, from mass storage to active sync. What I am attempting to figure out is if one of those modes has been enabled and the registry is just not accepting or if the usb port is stuck on only charging. I have no clue on how you would find out as I've never heard of that ROM. By the way, what version of TP do you have, GSM or CDMA and is it a RAPH100, RAPH110 or what ever is showing above the imei behind the battery. You should see a bar code and just above that are four (4) letters followed by three (3) numbers. Let us know what you have and maybe someone else can chime in.

EnergyROM 29018 w/CHT2.0&.sencity this is your rom ??? i can give it a try. how can i see if is GSM or CDMA ???? my phone is RAPH100.
tnks in advance.
p.s i'v had the phone charging for 2 hours and it's only 2 risks. :s

Clarification: It's not my ROM but it is a ROM that I use most often. GSM/CDMA depends on your carrier/service provider. Looks like you may have a GSM device but I'm not a 100%.
Additionally, what happens when you turn off(shut down your phone completely) and charge?

well i'm using vodafone. and the phone is unlock from factory. it was that the guy told me. i am giving a try with that rom. whit the phone shut down and usb turn on the home buton stay's whit the light. i'n the 3 color screen when i conect the usb it's allways saying serial and don't change to usb.

Not exactly sure that is what I am asking. So do this for me: remove the battery, then put it back in and without turning on the device, plug in your phone to a charger(not USB cable) and tell me if you see an LED circle around the center button slowly light up and then disappear.

yes is that what it happens. and it happens this to with the usb plug in. whit the phone on or off.

So let me guess here, does it still take forever to charge from 30% and still get hot when the device is completely off and plugged in. If so, it still seems like it could be a battery issue to me. I don't know how to confirm if it is the device or the battery but I'd start there if you haven't already.
Additionally, if you are getting to the multicolor screen, then connecting the device to your computer and not seeing the change from Serial to USB and you've already tried changing the USB port, USB cable and computer then it is possible that your device's USB port is somehow broken(for the lack of a better word).

"if you are getting to the multicolor screen, then connecting the device to your computer and not seeing the change from Serial to USB and you've already tried changing the USB port, USB cable and computer then it is possible that your device's USB port is somehow broken(for the lack of a better word)."
you are right i go the multicolor screen and not change from serial to usb. but i didn't try in other computers. i will tell you when i try.

Unable to connect to PC in any mode

Hi all, I'm afraid I already know the answer to my question but I'll still ask if there's even a slight chance to get this fixed on my own.
I had this issue on Android 8.1 where my Pixel kept saying "Supplying power to connected device via USB" even without anything connected to it, (it started doing that one day without any reason) tapping the notification allowed me to switch to "Charge this device" and then turn on MTP mode, battery life was terrible but I wasn't that much bothered by it because I am an Android developer so I kept it connected in USB Debugging mode most of the time anyway.
When I got the notification for Android 9 update I decided to update hoping it'd fix the USB issue but after the update it now always says "Charging connected device" and tapping the notification does bring up the "USB Preference" screen and it allows me to switch to "USB Controlled by this device" and it starts charging but there's no way to switch "Charge only" mode to anything else, ADB does not see it, fastboot does not see it and there's no persistent notification on the phone about it being connected via USB at this point (in any mode). My understanding is that this is a hardware issue but Oreo still allowed me to workaround this and get the USB debugging connected.
Is there anyway I can get back to Oreo without using fastboot flash or any other solution to this?
Thanks for reading.
PS. I'm on Ubuntu but I can access a Windows machine if required and bootloader is already unlocked.

I'm curious if you're able to connect to a USB OTG storage device.

I'm having this issue connecting it to my windows 10 laptop.. the cable recognizes it.. starts charging.. shows option on phone to change type of connection.. but not matter which one i change it too, the computer will not pull lit up as a drive to see the files..

Same here! I plug the cable into the Windows 10 computer, I even can change the mode from charging to MTP file transfer, but the device won't show up in the Windows Explorer. It appears under connected devices though.

My Pixel 2 XL would not connect to PC for file browsing if USB debugging of Android Apps was enabled in developer settings. Didn't matter which option I chose to connect. IDK if that is expected or not, but it took me a while to figure out. Happened Spring 2018, idk if Google fixed it.

I don't think i've tried to turn that mode off.. i'm so used to needing it on for the computer to recognize and connect to all my previous Android Devices.. thanks for the recommendation...

Couldn't find any OTG cable to try that but strangely enough a few days back I connected it to PC for charging and Nautilus popped up, same cable, same USB port and it started working all of sudden. Did verify with a couple of other cables and different ports and everything is working fine since.
"Charging connected device" notification never appeared again, only thing different (when it started working again) was that I was out of the air conditioned room most of those days, might it be moisture or something like that?
I'm back to my normal routine for a few days now and it's still 100% normal, will have to see if it stays that way.
Sorry for late response.

Here's an update in case someone else runs into this situation, I can say this with 99% certainty that is caused by the blackish residue build-up around the USB port over time. It's not too much that it's visible just by looking into the port but it's enough to make the device behave like this.
Here's what I did to get rid of it, took a match stick (don't use anything metal) and broke it in half making a sharp edge on both broken pieces, took the non coated piece and inserted sharp edge in the bottom side of the port and gently wiggled it around while applying some pressure towards the connector (just a little bit, make sure you don't break anything), did this for about 45 seconds then took out the match stick and the part that was touching the connector had turned blackish (I guess this is when you know you have 'cleaned' it enough?), repeated the same process on the top side of the port with a new match stick piece (guess you can use the same one after cleaning it with a tissue), the only difference was that this time applied the pressure in opposite side (other side of connector), device was on during all this time.
It builds up again after a while (~3 months) so I had to repeat the entire process again when it started doing that again at the start of December but it wasn't that annoying this time because I knew exactly what was wrong and how to get rid of it, device is still working fine 100%.
I'm simply sharing my experience and not encouraging anyone to do this but if you do decide to try this be sure not to use anything metal and don't break the connector inside the port (turning the device off would be a good idea too) and you'll be fine and if something does go wrong I won't be responsible.

Bricked Allview Wi901N windows 10 tablet

Hello,
i have a big problem with an Allview windows 10 tablet, during windows 10 reset i got a blue screen and my tablet got stuck into a boot loop restarting after windows logo appears. It didnt boot from windows usb stick that i made with rufus in multiple ways with different settings and when i was trying to get it boot from usb i accidentally disabled XHCI or EHCI from bios ,the attached keyboard does not respond, otg cable connected keyboard does not respond, touch not working.
Any solution will be greatly appreciated,
Thank you.

The only option I can suggest is to open it up, desodder the battery (as it's soldered to the motherboard). Wait for a couple of minutes (maybe even hours) and then solder the battery back in and see if the BIOS has been reset.
This may work similarly to taking out the CMOS battery and putting it back in.
I can provide you with this info as I've just stumbled upon your post having the same issue as you. I haven't yet tried this method as I don't have the tools required to desolder the battery right now but I'll post an update as soon as I can to let you know if it worked.
There's also a debug header available on the board but no resources online on how to use it.

Help me to Identify what pins to short (amlogic tv box)

I have an amlogic tv box that i want to revive. Its a generic chinese box.
With a lot of help of the community i managed ti identify the board, Is the one from this link:
https://www.szjytx.com/?id=13299
The one from the link (as you can see by the photos i posted) is the same one physically. The only thing i couldn't identify was the real processor (the manufacturer was faking it), because when i removed the heat ink, the painting on the chip got erased.
So i started to experiment with it.
I couldn't find any ROM for the processor that that chinese page says (S905L-B)
After various tries , I could install twrp (for the s905w processor)
The first working one was one for the "x96 mini", it worked but it only showed 1/4 of the total screen.
Then i tried one for the tanix tx3 mini, and it worked like charm, i could backup and restore roms.
---------------------------------------------------------------------------------------------------------------------------------------------------------
After that introduction, here's the problem:
The box has no reset button, so the only roms i could try were from twrp update zips.
So, as i did with the recovery, i tested first installing a "x96 mini" rom, and i had the same result, a bootable rom showing 1/4 of the screen.
The next was to try a "tanix tx3 mini" rom, and after the flash it never booted again (not even the logo), so i think is bricked at bootloader level. Te power led powers on, but no image.
I think my only hope to revive it is to flash a rom trough the amlogic burn tool.
The problem is that the device can't be recognized by the tool.
i only had partial luck /really strange behavior) with a malfunctioning usb male to male cable, testing it sometimes it got recognized for a few seconds (of course i couldn't install any rom with that little gap).
With a brand new male to male usb cable it gets nothing.
This new cable works, because the power led of the device turns on, but it doesn't get recognized by windows or the tool.
I know that there's a method to force the box to go to download mode, by shorting two pins, but i cant tell what pins are the correct ones, o some hint to it.
I attached pictures form both sides of the board.

I am having the same problem. Did you solve the problem?
