[Guide] How to record Call On our Galaxy 3

All Galaxy 3 Firmwares don't have the ability to record both streams of a call. This is not a bug, it was designed like this because in most countries it is illegal to record someone without their permission. Yes, there are apps that will let you record a call, but without software support, it will record the other end from the microphone, which will result in low quality, but there is a workaround.
This might be illegal in your country! I'm not responsible if you get sued for recording someone without their permission.
12.1 Download the attached "CallRecord.zip" and unpack it.
12.2 After unpacking you should have 3 .so files. You need to get these files into your /system/lib folder with either adb or by copying them to the phone and then using "Root Explorer" to copy them to the proper folder.
12.3 Reboot.
12.4 After the phone has rebooted, you can use most apps that are on the market to record calls properly (that means not from the microphone). I use AllCallRecorder because it is simple and does the job. There are also Phone.apk's that have call recording built in, you could also install one of those and record your calls with it.
Sorry don't use this . Not working.

Problem!!
Hmm.. Thought i was the only one. I'm stuck at Samsung logo for abt an hr now.
gonna try flashing ROM to recover. Nothing works as of now. Tried Factory Reset and Rebooting etc., Please be clear on the specificity of changing our Phone's settings It might not end well for all. And I don't know if it helps, I moved the files through Root Explorer and my phone is I5801.

Wi-Fi Drivers, libs

I want to know have can i solve my wifi problems without installing new rom on it.
What is the wireless driver, where are they in my system files?
We can fix the camera issues with changing camera lib files. Can i do that for wifi?
Wifi Problem is ;
I can connect wifi, first it was work fine. After several minutes it dropped and not connect any internet, after several seconds it reconnectted. It always keep going this way.
Can you please help me on this?

What ROM version are you running?

B137 stock and modaco.com/content/huawei-u8800-ideos-x5-u8800-modaco-com/342205/23-june-b137-r3-flb-custom-rom-for-the-huawei-u8800-with-online-kitchen/
I have two of them on my clockwork recovery. Both of them have same issue. I want to try other roms, but its too hard for me to give the time for each rom. So i want to try other roms wifi libs, driver, firmwares.

Not a fan of 137s I've tried so far...You should try these versions:
- V100R001C00B136 (Overseas General version) 2011-05-17
- V100R001C17B160CUSTC17D002 (China Unicom) 2011-04-29
http://wiki.modaco.com/index.php/Huawei_Firmware_U8800
To install any of the ROMs, just download the Huawei Firmware you want and unzip it, there should be a folder called "dload" copy that folder and its contents to your sdcard.
Power off phone then hold both volume buttons while powering on the phone, the update should start.
I don't understand why you think it's easier to change a lib/driver and spend a huge amount of time trying to get it to work, when it takes 30 minutes to install a new ROM and all previous applications, if synced with a Google account. When I first got the phone, I've installed like 6-7 ROMs in a matter of hours...
So, in my opinion, you should try the B160 or B136 before you actually start fiddling around with libs.

Are you read my first post ? I Don'T want to try roms. Install new rom, try wifi, over and over. End when find it, wait for the all install downloaded. Chancge launcher and other apps to what you want. It is just boring. I try 4 different froyo roms and nothing seems worked. If i know the what file i must replace, i just have time. Many many more time.

) I've read your post, but if you think this is windows, where you can just change the wifi drivers, you're in for a treat . The newer ROMs wifi is fine, so whatever you're doing, you're obviously not doing it right or you have a faulty phone.

I don't understand a thing from your post. Are you understand me?
IF IS A WINDOWS, I CAN CHANGE DRIVER FROM SYSTEM32/DRIVERS. Or install new driver for it. Newer roms are for WHO ? Mine and other my friends in turkey, have same problem. Even they updated the B137 with updata.app from original sources.
Please if you don't know or understand my post, just leave it to be. Obviosly i can't decribe my problem to you.

The whole windows thing was a comparison...All I was trying to say is that upgrading drivers is NOT EASY, as the problem may not be in the lib file.
You better go and learn some ENGLISH, before you try and understand the answers you're given. ) quote "Are you understand me?"

Very very few people have wifi problems like you are experiencing. This isn't to say it doesn't happen as obviously you are having issues, but it's not a rom issues. It's likely that your problem is either a hardware issue with the phone or an issue with your router settings.
Currently there aren't any alternative wifi libs you can try since all the roms are using exactly the same wifi libs which are located in the kernel image, not the system.

I've been experiencing the same problem -international B136 ROM- however I think it may be the router that is the cause of it. Whilst in the main house with the new wireless g router, no issues, everything works fine. In my extension with the old wireless b router the problem happens all the time.
The problem doesn't really bother me to much, but I thought I'd add my 2 cents just in case you were after some more information on the issue =)

guys, I recommend reading my post in the general section with subject "Wifi Client Tuning ... solve connection problem "

i have simillar wifi problem. When i connect my airties modem,my internet connection is vere very slowly(60-80kpps as speedtest program) How can i fix this problem? Do you think b136 or b160 could fix it?

Definitely, if you've got something like B133, the first thing you have to do is upgrade to 136-137 or 160. You will see huge improvements in terms of Wifi.

is there any problem in b136 or b160? Which one should i apply?

In my view, the best of stock ROMs is B160. The battery lasts longer and it's got less problems.

how can i see my rom version? and do u send offical b160's link?

Go to Settings >>About Phone and scroll down to Build Number. It should look like this U8800V100R001C00B133SP01 and the bit that interests you is B133 or whatever version you've got.
Since Modaco Wiki is down, try this link:
http://www.filefactory.com/f/0f067250fb54623e/
B160 is called China Unicom in that list.

I've managed to get a cached version of Modaco Wiki that is currently down.

Installing now. Let ya know if any big changes, anybody check and see if there's a new hw package update as well to go with?

I dont think so...theme manager still now working... and after flashing,phone still say on c654b300

So...what do you think of new firmware ?...
Personnally,i often have to reboot phone so changes ,like in sound,notification can be changed...also when passing to wifi to data,i also have to shut down wifi then reboot so data will turn on..
Theme manager ,no way to make it work
Ive found theres almost no lag compared to previous firmware,changes have been made to lockscreen ( personnal infos in the middle instead of on top of image)...
When cleaning the phone via app,settings are always ****ed up and have to re do them like, to not shut down facebook/messenger to receive notifications well,after clean up,i have to re do all settings...
Dunno what huawei is trying to do but, There is always something not working.
Also,Aida64 says its a Release Key version...when looking in the Android tab...

Attached are some pics...the firmware is supposed to be C654B334 but shows C654B300...

Hi...what will it do ?
Only change the build nuber or other things are included ?
Thanks

It should fix a couple of minor issues I am not sure what tho and yes the Build number too. When I on the CAN-L01C432B320 build for my phone and updated to CAN-L01C432B340 it was still showing up as CAN-L01C432B320 until I installed the smaller update for my phone.

Thanks...did the update...now 334...
Ill see if it did something

Heres a thing that really bugs me...
If i look into the update folders once extract,i can see some themes / pictures in ... C:\Users\portable\Documents\update_data_full_MLA-L03_rogers_ca\data\hw_init\version\region_comm\oversea
why is theme manager / magazine still dont / never works ?
and even after installing the update,i dont see the themes and magazine images... There must be something wrong somewhere.
Is Huawei/emui blocking the app intentionally and if so,why ??....Im just trying to understand things.
and most important thing is,when writing to Huawei,we never get real answer...always the same thing....''wait for next update''
also,in the changelog,it clearly says...
''5. If you are not satisfied with the new update, you can roll back to EMUI 4.1. Your personal data will be erased during the rollback.''
Nowhere in the phone's setting (ive searched everywhere) its mentioned a way to revert back to mm6...Also in the 2 or 3 button way it says revert back to mm6 ect.

Could someone give me the real apk name for the (nougat)Emui 5 theme manager apk please ?

My theme manager is there and shows any themes I DL and put in the theme dir. It's not a theme store just a manager. Is it not there at all, or not working properly?

Hi..
Whatever i do in theme manager,it wont work whe applying...
If i dload a emui5 then well when clicking on apply ,its supposed to apply the whole theme...even if i apply thing separately,it wont change at all.

[MOD] [VR] [Dev] Samsung Gear VR on other devices.

Hey guys so last time I used it a few months ago this was how I got Samsung Gear VR working on my LG V20 rom. For those DEVs that would like to add this feature I thought we could all work together to get this on every device that is running 1440p screen just for quality reasons.
This is for devs only not a flash able zip.
Extract the contents and just copy and paste the info in the build prop.

Change Log
Version 1 - What has worked as of 4/4/17 on the LG V20 Ti-X Rom

Possible to slim it down (Apps)? To include 174Mb in the System is a bit much for that few Users who'd own a Gear VR. Maybe I'll be better if You provide it as flashable Zip. If You need help with that i could be Your Man!
BR and cool stuff btw!
De-odexing could be also a good Step besides pulling it from the System Image instead of dumping it from a running System. But just a suggestion....

Im about to compress those apps to see how much i can save but i need to finish installing a new os. If you want to make a zipable you can ill post it up and can givw u access to the google drive.

I know this is probably a stupid question, but I'll ask anyway:
Where do you copy the contents of the app-private folder
Are there any other instructions? I remember I had to get this to work on a rooted samsung and I thought there was suppose to be some service running for the gear vr software to kick off when the device is connected.

I will make a lovely flashable AROMA based ZIP this Weekend. I can also improve the Size a bit by using my optimized Compression methods. Think the Size isn't that important as standalone ZIP, but some Users have slow connections and bad Data Plans...
I don't own the Gear VR but things like that have to be supported! It's a step in the right direction (Android shouldn't be used to include OEM exclusive Features dear Samsung! Share them!)
BR

So I understand you copy it to app-private in data, but that doesnt give you the software. Does anyone. Have a zip with the required apks needed to actually launch the vr setup wizard?

200MB is not that much gain when most roms will have 500MB+ removed and the system portion would be un changed so free space would be sitting there to be taken up.

Oh so this has to be done before you even flash your phone, you can't add Gear VR functionality after your phone has already been flashed. Sorry I misunderstood.
It would be cool if this was a separate package that could be added to an existing phone with root access.

My way was just how to add ot to a none flashed rom if you throw these files in your system clear cache is should work also if you set the permissions correct

Would you still copy it to app-private in that situation? I tried that and it wiped the folders from the app-private, but did not install any of the applications.
Nougat 7.0 lg v20 sprint. Maybe I am better off installing your rom which will just have it working???

this is great news been trying to get this working on my S7 active ! tried boot.prop changes but no different
as its just software stopping it working, as hardware is pretty much identical ..
did try from here https://forum.xda-developers.com/mobile-vr/gear-vr/port-gear-vr-software-to-android-device-t3540402
but couldnt get it to copy properly, so wouldnt work ..
once rooted, is it just a case of coping over, can this be done via say ES.Explorer ? ..
does this then enable the auto detection when pluging in ? and the touch pad and buttons too ? ..

This looks super interesting. I've got a V20 running AOSP & I'm going to play around with it after work

If you just copy and paste the folders inside the priv app folder think there's like 7 it will be just fine if you copy the priv app folder it might not merge and just replace. I had to factory reset for the apps to get all the correct permissions not sure why.

Not familiar with your custom ROM but many people don't properly install custom ROMs
Did you FORMAT (not Wipe - it's completely different thing) Data partition (!) when you switched the ROM? If you didn't, you must do it
Assuming you had audio with the official MIUI (otherwise, you may have hardware issue)

ive done that. after flashing a ROM, I format data..
My audio was working before I custom ROM too. idk if i should just go back to stock rom

UPDATE:
I've tried several custom ROMs now, also stock ROM. But no luck. How am I supposed to know if this is a hardware issue??
WHAT'S NOT WORKING:
- Built-in speakers
- Video recording
- Screen recording
- Voice recording
- Headphones/Earphones
- Bluetooth earphones/speakers
- No audio calls, no ringtones
- Unable to disable/enable mute button during call
- During call, speakers are enabled but cant be disabled (still no sound)
WHAT'S WORKING:
- Adjusting volume sliders
I'm not sure if this has something to do with hardware since I dont recall it falling, etc.. It suddenly stopped working at all.

There are codes that you dial and you can test all your hardware separately. It depends on rom, so you have to try

man we have the same issues. my device has no audio source since i switched on custom rom. i tried to back again on stock rom but it doesent work again. the technician recommend to replace the audio ic which is hardware issues. anyone can help us on this problem? my device is mi 9t

Try to wipe all, including recovery. Don't install newest rom, try older like android 10 and then if it doesn't work, you can try editing propsconfig

If you have Magisk, use Magisk Hide Props Config module to add/edit/remove any prop
Otherwise, from TWRP, Advanced, File Manager (for e.g. build.prop file) go to /system and copy the file build.prop to /sdcard.
Reboot to Android, edit your copy of build.prop saved to Internal memory.
Reboot again to TWRP, mount System as writable, copy build.prop to e.g. build.bak and copy your edited build.prop from /sdcard to /system
If anyting goes wrong, reboot to TWRP, remove your build prop and rename your build.bak back to build.prop
You can also copy build prop from TWRP to PC, edit it there and copy back
Google for details if you are unfamiliar with, this is just general idea
If using TWRP, make sure you make a backup file (like build.bak) to be able to resolve possible brick or something
If using Magisk and that MHCP module, changes will be systemless (google if not familiar with the term) and you can simply disable the module (and automatically all your changes on props) if anything goes wrong
Generally, it's not for beginners to play with props

If anyting goes wrong, reboot to TWRP, remove your build prop and rename your build.bak back to build.prop
You can also copy build prop from TWRP to PC, edit it there and copy back
Google for details if you are unfamiliar with, this is just general idea
If using TWRP, make sure you make a backup file (like build.bak) to be able to resolve possible brick or something
If using Magisk and that MHCP module, changes will be systemless (google if not familiar with the term) and you can simply disable the module (and automatically all your changes on props) if anything goes wrong
Generally, it's not for beginners to play with props

Thanks for explaining everything brother. Now I will do a research about editing audio or sound on build prop. Hopefully this is not a hardware issues.

Same issue encountered with me also. I am in a great distress right now. Tried more than 30+ roms (including recover, fastboot, custom, and stock), but nothing helps.
IF you find anything please update here.. THat'll be a great help indeed!!

UPDATE:
I've tried several custom ROMs now, also stock ROM. But no luck. How am I supposed to know if this is a hardware issue??
WHAT'S NOT WORKING:
- Built-in speakers
- Video recording
- Screen recording
- Voice recording
- Headphones/Earphones
- Bluetooth earphones/speakers
- No audio calls, no ringtones
- Unable to disable/enable mute button during call
- During call, speakers are enabled but cant be disabled (still no sound)
WHAT'S WORKING:
- Adjusting volume sliders
I'm not sure if this has something to do with hardware since I dont recall it falling, etc.. It suddenly stopped working at all.

If you r getting error while playing ringtone through settings then its your ui problem. You have to shift custom ui i recommend pixel UI or Oxygen os
