Do you know if i change the Mosfet and solder a new PA2030A, the RCA sound will improve? Or this chip only affects the direct speaker output.
[MTCD Hardware Development] marchnz:
Read forums. Improvements are placebo effect.

Add external amplifier and be happy

Thats why i was asking if i can do any upgrade on my unit to help improve the noise.
[MTCD Hardware Development] marchnz:
Yep, known issue with these cheap Chinese origin units. Have a scan through forums.

Consider replacing with optical out unit.
[MTCD Hardware Development] angelparras:
You mean replacing the entire head unit?
[MTCD Hardware Development] Cutprods:
It isn't necessarily a known issue with all Chinese Head units. Mine, (Xtrons/GS, PX5/Oreo 8, 4/32 of 2018 vintage) in my Audi A4 B7, non-Bose, which is only half amplified and therefore relies upon the Xtrons for the other amplification, has never had hum or interference, from day one, and I work professionally with audio/video equipment and production, so I would certainly recognise it. Hum or background noise is most always a grounding/shielding issue and often impedance mismatching to aftermarket amps/ speakers such as you have. Whilst these head units are in no way of the highest quality construction, and their shielding can often be very sub-par, that would show itself after DAC and within the analogue section, which could be somewhat alleviated by certain modifications.

I agree totally however, that changing the amp chip, would not be one of them and is an unnecessary placebo. :)
[MTCD Hardware Development] maselz:
I changed the chip of my Android multimedia. It had yd7380 on it, I installed pioneer pa2030a. I couldn't replace the capacitor because I couldn't find it. As a result, the sound did not change at all.
[MTCD Hardware Development] marchnz:
Yes. There's very little to gain.
[MTCD Hardware Development] iabidali:
I have YD7388 in unit, can I replace it with the PA2032A? Both have 25pins.
[MTCD Hardware Development] marjanoos:
What part of this didn't you understand?
[MTCD Hardware Development] maselz:
Sonuç değişmiyor kardeşim. Üstüne benim cihaz şimdi ses kesiyor. Bence uğraşma.
[MTCD Hardware Development] maselz:
Friends, I changed the sound integrated circuit, there was no change in the sound. Now I have another problem. After working for 10 minutes, the music constantly cuts out when the volume is high. When I turn the volume down it goes back to normal. Do I need to change the capacitor? I wonder if the power is not enough? I'm waiting for your help. Kind regards.
[MTCD Hardware Development] marchnz:
Depending on where you brought the replacement IC, it is counterfeit or inferior binning part.

Likely Power amp IC is going into protect mode.

That could be an issue with the IC, dry joints, or overload. If thats ok and you are sure you have a genuine IC, check wiring of speakers and speakers for issues, or speakers for ohm/short.

Ps. There is little to gain from replacing the power amp IC, fit an external for meaningful performance improvement. Endorsements from users replacing the IC for "upgrade" is placebo affect/cognitive bias. So says the Power amp IC spec sheets.
[MTCD Hardware Development] maselz:
I didn't quite understand. Could you elaborate on the subject a little? If I change the capacitor and give more power to the sound chip, will it be fixed? 10000 uf is like 25 waat. Because when I turn up the volume or play bassy music, the sound cuts out. There was no such problem with the previous sound chip. I plugged this Pioneer PA2030 into it and the problems started.
[MTCD Hardware Development] marchnz:
No. Read my post again perhaps.
[MTCD Hardware Development] Cutprods:
Marchnz suffered, so we might avoid, years ago, changing all this stuff on the PX5s - and time and time again, the message he has outlined, been clear - nothing whatsoever to be gained!

The single biggest overriding issue with these old HUs is 2.4GHz wifi, that suffers even more (sometimes drastically) when the BT is active. I solved that with a Motorola MA1 5GHz dongle and AA. There's nothing really wrong with the rest of the chips; FM, amp etc. Even a DSP/or digital equipped unit has to enter the world analogue wise in a car and the ambient noise in a car is far from Hifi living room standards. Your car's speaker/amp system is the critical component and some cars have diabolically poor systems that no DSP can sort. Perhaps I've been lucky but since whenever I fitted my unit, 6 years ago; the Audi A4 B7 Avant non-Bose had a great system to start with and the GS PX5 was plug and play; no interference and as good if not better audio quality, than the Symphony II it replaced. So I've left well alone, on good advice.

The FM chips too, whichever are usually the same that came on the branded ones; poor FM/Dab purely an antenna issue, normally because odd OEM Diversity systems fitted to a lot of noughties and newer cars; and here FM/Dab is sh1t anyway.

Of course, I understand the hobby apsect, of messing ;)

[iPAQ rw6828, XDA Atom Software Upgrading] brian_2cool4u:
1. what ROM did you download?

2. did you flash via bootloader?
[iPAQ rw6828, XDA Atom Software Upgrading] chibineko:
1. Official WM 5 Rom & Jigg WM6 Rom, both i try also can't....:(

2. U mean the black screen by press camera + reset? yes.

-------------------------------------------------------------

Just now i can use the touch screen but the radio and some other module is missing....:(

considered to flash it again.....
[iPAQ rw6828, XDA Atom Software Upgrading] brian_2cool4u:
maybe you have downloaded a corrupted ROM. try to download it again then reflash
[iPAQ rw6828, XDA Atom Software Upgrading] chibineko:

yewp, it was radio stack..sorry.....

so my device really no more hope?

------------------

now it stuck at utility update screen......

try tae out the batt & camera + reset it, also fail....
[iPAQ rw6828, XDA Atom Software Upgrading] tjkhattak61:
[FONT=&quot]Try this:

Get hold of Original O2 ROM for ur device and extract all files to ‘C:\WINDOWS\Temp’ directory and then replace ‘Device Software Update Utility.exe’ with a newer one through which u can Flash in parts. After attaching the USB start the upgrade and instead of ‘ALL’ select ‘OS+EBoot’ only by pressing tab key and down arrow key.[/FONT] May be it will boot in a normal way.
[iPAQ rw6828, XDA Atom Software Upgrading] chibineko:
ok, that really help me to get the device to alive..Thank..

but the radio stack problem still there....>.<!
[iPAQ rw6828, XDA Atom Software Upgrading] tjkhattak61:
chibineko, if ur phone is working alright then hmmmm might be software problem only. Try to flash the original ROM for your Atom from O2.

I have a T-Mobile Galaxy S8 (SM-G950U) running Android V8.0.0. Long story short, my device is unable to connect to my service provider. I tried resetting the network settings, factory reset, wiped the cache under the Volume Up + Bixby + Power function. I remember having similar issues with another device and t-mobile outright refusing to help me because it was out of warranty and flashing the modem file thus fixing the problem , but this was years ago and Odin now seems unfamiliar and I'm having trouble finding the files to flash . Any help would be appreciated, as I'm currently a broke, without a phone, and I'm still paying for them damn thing.

[8125, K-JAM, P4300, MDA Vario General] strykur:
Hello Wizard Owners,

Last night, while plugging my Cingular HTC 8125 into my charger, I pushed a little too hard, and had the mini-usb held at a bad angle. The furthest left and furthest right charging pins bent and are now broken off inside the phone. The broken off bits have since been lost, and now when I plug in the mini-usb charger--my phone will not charge. Is there anything I can do to replace the charging pins or modify the phone so it will charge properly? Or do I have a nice expensive paperweight now? Thanks for your help in advance.

Multi window gone

My phone just updated and now my multi window feature is gone, I've gone thru every setting to find it
[Samsung Galaxy Note 9 Questions & Answers] Knaapie:
When viewing you're recent opened apps, each app has their icon at the top centre of it. Click on the icon. You'll get a small pop-up menu with options. You can choose: App info, open in split screen, pop up mode (where you can resize the app) and lock it.

I don't know yet what the lock functions does.

EDIT:

As mine is in Dutch, could be that the lock function has a different name in English.

The lock function: If you lock an app, and then close all recent apps, the locked app wil stay open. So if you're playing a game, you can lock it, close all recent apps and the game will stay open and running.
[Samsung Galaxy Note 9 Questions & Answers] high_voltage:
Yep, that was also removed. You can't popout the selected app, you can't switch app places. So, if you opened firstly viber (for example) and then youtube at the bottom and then decide to switch the apps place so you can type on viber without covering the youtube video - tough luck, now you have to close both app and open them again vs 2 taps in 1-2 seconds that will not interrupt anything. Also you miss the popout swipe from corner as said from others. You also miss the swipe up + hold for instant split screen (really useful when you play a video @ youtube, will not interrupt the video). You have the swipe up + hold for google assistant... but you don't have the same for the recents - go figure why (never mis-triggered the assistant, so it's not that). So many things are missing, half baked or straight forward broken - really disappointed. I like some aspects of the android 9 one UI, but others are just mind blow not polished at all or missing. I guess to have a "new" things for one UI 2.0 or note 10. After all, why you need a good multiwindow functionality on a phone marketed for multitasking and multiwindow? The note 9 really is more than ever an s9+ with a head scratcher. :)
[Samsung Galaxy Note 9 Questions & Answers] Millispy:
Just to add to this, you can switch between multi view and currently open apps by holding down on the previous apps button for 2 secs then you can choose by 2 second press if you want multi window or just currently open apps.
[Samsung Galaxy Note 9 Questions & Answers] Bo21:
I don't like that if you want to choose an app not in the recent window, you have to close all to be able to choose an app. Their multi-window has taken huge steps backwards. Kinda disappointing since that has always been a defining feature.

Well, I will correct myself, you can swipe to the home screen while choosing and select a different app that is not already in the recent window.

Other pie screwups

That's not all you've lost, my friend. The multi window setting is gone, as you know. The ability to swipe from the corner to resize and go multi window is gone, as you know. However, additionally, i noticed the following:

- The ability to enter your fingerprints to access Samsung browser secrecy mode is gone/disabled. You can only enter using iris scan or password.

- The phone optimisation edge panel is gone and nowhere to be seen.

- when you deactivate the nav bar in favour of swipe gestures, you cannot long press on the recent apps swipe area to enable split screen multitasking, as you would have with the recent apps button on the nav bar.

I hope there's a bug fix coming and soon

You can also swipe the multi screen spliter inbetween each app to fully open the bottom app and then select a different app for the bottom... it's still hokey but quicker than exiting out of both apps
