[8525, TyTN, MDA Vario II, JasJam General] ultramag69:
All I can suggest is to try cleaning the contacts (both on the motherboard and the speaker) with Isopropyl Alcohol, or surgical spirits for the layman, to see if there is any corrosian present.

Use a cottonbud dipped into the alcohol. DON'T USE METHO... It leaves a residue.

Trying to track the sound circuitry isn't really feasible as the Hermes Mainboard is multi-layered and is a ***** to try to work on. You'd destroy it instead of fixing it.

Cheers...:D
[8525, TyTN, MDA Vario II, JasJam General] uengin:
Ok, the thing is, I have had another working hermes, so I swapped over the speakers, both the earpiece speaker and the rear speaker, they both work one, but not on the other, with the contacts being cleaned and the connectors bent out abit to facilitate a more firm connection. I am pretty certainly convinced that my issue is not a contact issue. If I had a CRO I'd hook it up to the CRO to see what kind of voltage levels are produced at the contacts but I dont have the luxury to do that. Multimeter isn't too useful either.

But I just thought if I could get somehow, even a vague circuit for the audio maybe I could find a damaged resistor who's impedance has gone through the roof or some thing.... I dunno
[8525, TyTN, MDA Vario II, JasJam General] ultramag69:
All the resistors are surface mount so being able to replace them is a BIG deal. It requires a fair bit of skill and a steady hand.

If you find the problem, good luck with the soldering...

You might like to PM Mike Channon or visit his site (at the bottom of one of his posts) as he is considered the guru when it comes to hardware. He might be able to give you an idea where to start and a few pointers.

Cheers...:D

Thank you all!

I had a broken rear speaker for about a month. I hate opening up anything that I paid more then $5 for, but this is an easy fix. I didn't even need to take off the back panel the whole way, I just lifted it up and found the white connector right on the side and pressed it down with a mini screw driver. Hopefully it will last, I just finished.

My HTC one have a problem with outgoing calls, sometimes when I call someone I can not hear call tone and the interlocutor hears nothing too.

please, find me a solution.

thank you.

I've noticed mine has started doing this in the last week or so as well. Weird.
[One (M7) Q&A, Help & Troubleshooting] ririo:
Same think for me since I went to 4.4.3. When this happens no outgoing calls are getting through, but also incoming call are lost. The only get around solution is to restart the phone.

My Rom is full stock, the phone is not rooted. All other functions are runing fine.
[One (M7) Q&A, Help & Troubleshooting] Howie3045:
Im stock developers edition 4.4.3. Haven't really done anything with my phone since i installed the DE rom. everything else seems to work but calls act weird. I too have to restart to get it working right again.
[Galaxy S 4 Q&A, Help & Troubleshooting] DArkSm4sh:
So i bought a new Galaxy S4 19505 and i like everything about this phone till i found a major problem. Any picture or video on the phone doesn't show up in the stock gallery, only the pictures or videos taken by the camera application would show up. I told myself that this isn't a big issue and i installed quickpic which is somehow better than the stock gallery and works perfectly. However today i discovered that my phone doesn't detect any ringtones installed or any alarm tones! the same goes for the notification sounds, the three lists are just empty!

I tried installing several media scan applications from the playstore, i understand that such applications manually trigger the Android Media Scanner to run so it would detect new media files but unfortunately all of those applications fail on startup.

Now i suppose that my media scanner file is corrupted, so is there anyway i could replace it?

Thanks in advance.
[Galaxy S 4 Q&A, Help & Troubleshooting] Skipjacks:
Assuming you have correctly diagnosed the problem (which I have no idea) then what you are describing is a corrupted system file.

As long as it's only a system file that is corrupted and not the storage card itself, you should be able to fix this by using Odin to reflash your stock firmware. This will wipe your phone clean and restore everything fresh. And I mean everything. So if you have photos or music on their you want to keep, put it on an external SD card or move it to a PC or something.

This will wipe out the corrupted system file and replace it with a good one.

You can also root the device and install custom software, which will basically do the same thing but give you a completely different operating system. (Well...somewhat different. It'll still be Android. Just a different flavor.)

If the internal storage is physically damaged, then there is nothing you can do.
[Galaxy Tab 4 Original Android Development] logikism:
Development? Anyone?
[Galaxy Tab 4 Original Android Development] BookCase:
There is one guy I saw posted on a rooting thread that he has developed a ROM for this device but, does not know how to write the updater-script so he is looking for help with that. Perhaps you can help.

You can find that post HERE

i wish! i know nothing about development. :crying: i would love to learn. but that doesnt help anyone here. i started a step by step to port CM but got stuck because i couldnt find kernel source. :eek: PLEASE someone, we got root, now get us off touchwiz!
[Galaxy Tab 4 Original Android Development] BookCase:
I have ported roms in the past to Kindle Fire HD from the Nexus tabs. It's way easier to port than to build a rom from scratch. The tricky part is finding the easiest roms to work with.
[Galaxy Tab 4 Original Android Development] logikism:
Well I can't do either.

Wouldn't we want to get something on here other than stock?

I'll take a port! Lol
[Galaxy Tab 4 Original Android Development] BookCase:
I'll look around, see what might work.
[Galaxy Tab 4 Original Android Development] sub77:
here you can find the kernel source http://opensource.samsung.com/reception.do
[Galaxy Tab 4 Original Android Development] nl3142:
Well I would think that you would need a working custom recovery with external SD card support first. Though the big feature I am looking forward to is a kernel that supports Roehsoft Ram Expander (swap) which while it works fine on my S3 does not work at all on the Tab 4 7.0.
[Galaxy Tab 4 Original Android Development] BookCase:
There is a fully working recovery with SDcard read/write support as mentioned in THIS post.

What I did was downloaded the TWRP 2.8.0.1 .img for t230 then flashed it over the older non-working TWRP using #Rashr. It works for me on SM-T230NU and wipe works. Dalvik/Cache, everything.

I already have root (by using vroot and then replacing the chinese app with supersu). Can I just flash TWRP with Rashr or do I need to redo the whole thing from scratch?
[Galaxy Tab 4 Original Android Development] BookCase:
Hmm, I have no idea. Worked for me in one go. Maybe start over?

I resstored the device in odin to the latest factory firmware then flashed the twrp in odin, rebooted directly to recovery and flashed supersu. Rebooted to system, set up all my stuff and flashed the new twrp over the old twrp using rashr. I had to reboot once to set up rashr before i could flash but, it all worked perfectly for me
[Galaxy Tab 4 Original Android Development] logikism:
cant start over if it wont turn on at all and i believe the battery is dead and it wont charge.

ive read about this issue with other galaxy tabs (2,3) and i need to open up and disconnect battery, i will try this when i get home. i hope it does something after. i just got this thing.

i cant just flash the good twrp instead of one over the other?

I don't know. I'm just telling you what I did. I didn't try that way.

It wouldn't be that bad if it wasn't so hard to modify this thing.. I'm waiting for 3Minit Battery to work on my 230NU =(
[Galaxy Tab 4 Original Android Development] troy5890:
Yeah its not so bad. I'll just have to get use to this stock rom for a year or so but that's the limit
[Galaxy Tab 4 Original Android Development] Shinare:
I gave my tab 4 7.o to my wife and reinstated the Nexus 7 (2012 ed). Everyone is either returning the 7 or giving it away.
[Galaxy Tab 4 Original Android Development] gammaxgoblin:
no point in rooting this thing....2 roms which are marginal improvements over stock anyway. I appreciate the DEV efforts, but they cant get TW out of it, so it is what it is.
[Galaxy Tab 4 Original Android Development] troy5890:
You make a great point. Right now I'm saving up for the Asus zenfone 2.
[Galaxy Tab 4 Original Android Development] Sultanxda:
Recently got this device for my dad thinking that it had an MSM8226, and then I found out it had a PXA1088. TW was sucking (especially WiFi), so I tried building CM11 and after 3 days, finally got the piece of crap to boot. Out of any device I've worked on, I can safely say that Marvell processors are the absolute worst for custom ROM development. Even though I got CM11 booting, graphics were absolute crap (laggy as hell), and everything else was broken. It was a very painful 3 days just getting CM11 to boot (it should not have been this difficult, especially since the stock ROM is KitKat), so I'll be returning this piece of garbage and getting a much nicer lg gpad 7 with a Qualcomm processor.

If anyone is interested in working on CM11 for this device then let me know and I'll upload all of my latest sources for you.
[Galaxy Tab 4 Original Android Development] DUHAsianSKILLZ:
You should make a thread about this in the development section, so someone can continue there hopefully... Great job getting it to boot! Most liekly someone will chime in and help

One last thing: after your experimental builds failed (because of secure discard), your /system partition should now be corrupted, so it needs to be reformatted. In TWRP, go to Wipe -> Advanced wipe -> choose System -> press 'Repair or Change filesystem' -> Change File System -> EXT4

I4A,

those patches appear to be for android-5.0.0-xo4, i ran a build cm11 without the patches just to see what would happen and went clean through.

I'm building blind on this device [philz/cwm] try repo init to cm12 or undo the patches to cm11 and get a build through and then work backwards.

Also, it's alot of reading and hunting but, the tab3 7.0 developement efforts [marvell] may have something useful to offer,

http://xdaforums.com/galaxy-tab-3

ran into trouble with /vendor/marvell/generic concerning ionhelper so removed that as well

was there anything useful in the platform archive that's included in the stock kernel source from samsung ?

I4A,

okay, if your recovery build functions then your kernel source should be mostly square.

Now your are looking into what is need to modify in the the android source/tree

and for that you will need to start reading the information generated by owners and developers of this

device from thier attempts,

http://xdaforums.com/tab-4/orig-development/roms-t230nu-t2887292/page3

I don't actually own this device, my recovery build was blind and i had a tester with the device helping me.

You will need to scour XDA for all articles and subjects concerning the marvell pxa1088 chipset , and may pxa988 as well.

There may be some usable info in that look for device trees for the galaxy tab 3 7.0 sm-t210/r.

Investigate those configurations for options missing in your device tree and also for marvell related patches needed

to apply to build system. I am assuming your are working in cm11? If so be aware that some proposed patches may be geared

for cm12 and may not likely apply or function "out of the box". At this point the adventure becomes yours alone, if there are basics

i can help out with, i'll see what i can do but, without having the device and developing it my knowledge on specifics is

extremely limited.

as to inacessibility via adb it seems issues with graphics can interfere with connectivity and device registering

[Galaxy Tab 4 Original Android Development] Sultanxda:
I didn't really care about actually fixing it, so I just took the dirty route and removed what was crashing mediaserver (I'm pretty sure it was /system/priv-app/TelephonyProvider.apk).

To gain ADB access you need to modify the ADB-secure flags in default.prop in the boot.img
