Buttons... They work!!

Hi,

Got to register to thank all who has given helpful comments on this thread. I managed to change firmware of my new screen's buttons. I think that post's number #134 is flashed into my brain for quite some time.

Here's what happened. I had S4 i9506 with all necessary app installed and happy with stock rom. Then dropped phone and screen got broken (lcd leak, glass was ok). Ordered new screen from Aliexpress and screen had 0x1b fw on buttons... which did not work on latest Lollipop. So,

I bought S4 i9505 with broken screen, took out motherboard and placed it into i9506 display/digitizer frame. And installed Albe95 S6 Full PORT ROM 4.7 which change touch key fw from 0x1b to 0x1c.

After I took out i9505 mb and drop in my i9506 mb.. Guess what :o buttons working!! :victory:

Hi everyone. I'm a noob and I'm trying to tread carefully. I have an original screen and stock samsung FW that broke the softkeys after upgrading to i9505XXUHOJ4, knox 0x0. I would like to keep knox 0x0 to keep using my bank app and screen mirror. I know how to use odin and flash but that was pre knox days. Is there anyway to do the solution from #134 and keep knox 0x0? Would I have to root the device through towelroot or some sort of alternative?

Sorry, I do not understand. I have the 9506 so Albe95's rom can not be used. Since that rom can push the firmware of the buttons to 0x1c, there must be a way to do it for the 9506 also.

[Galaxy S 4 Q&A, Help & Troubleshooting] OpenCollective:
This worked for me.

I had this problem and used a few hours today trying to get the buttons to work, I used the above solution and now everything is working perfectly. I just wanted to let people know that instead of googling around for hours trying to find a simplersolution, just try the above first. If you just do it step by step it doesn't really take that much time.

1. flash TWRP using Odin

* (flash latest bootloader for lollipop? not sure if this is actually needed....)

2. Download the above 4.7 Rom

3. Put it on your phone/SD card

4. Start TWRP recovery

5. wipe data, cache, system, factory settings etc (look at installation guide for more details)

6. flash 4.7 rom

7. reboot and let phone start (takes a looooong time, at least 12min so just be patient and wait!)

8. go to the *#2663# screen and check to make sure it says 0x1c on 'Part's Touch key FW version'.

9. (almost there!) turn off phone and boot into download mode

10. using Odin, flash latest stock rom of your choice

Keys should now work, at least they did for me. I just wish I'd followed the guide from the start instead of googling around, would've spared me hours (although I now have that great feeling of accomplishment :D)

Is there any solution for i9500 ?? :(
[Galaxy S 4 Q&A, Help & Troubleshooting] jamesteampro:
I tried this today, after months of using the onscreen back button. I was hesitant because stuff usually goes wrong, for me.

So I install twrp via odin and then backup my device. Then I install the 4.7 rom, no problem. My parts touch key is now 0x1c, but the rom itself is almost on self destroy mode, telling me that everything has stopped working. When I tried to install my stock rom again, I got an error. So I redownload it, try again and same error. I then install a different stock rom, which should have also worked but didnt.

In the end, I decided to use TWRP to see if I could restore my phone using my backup, which worked 100%.

So now I have parts touch key 0x1c, BUT my back button still doesn't work. No lights or anything. Still stuck with accessibility mode. Frustrated but at least I still have a usable phone. Good night. :eek:

[Galaxy S 4 Q&A, Help & Troubleshooting] SpamDamn:
I had the same problem with the soft touch keys not working. I tried the *#2663# code to check what firmware the chip was on and it did not show the touch information.

That led me to the conclusion that there's was a bad solder joint on the ribbon (to the bottom left of the battery) cable where the touch sensor chip is located. I used a heat gun to gentle do a reflow and it's now working. So not everything is software related.

If you are going to do this you'll need to remove the logic/motherboard from the phone then wrap your phone in a layer of aluminium foil and then wrap that in a thick layer tissue and then wrap again with aluminium foil, obviously the flexi cable needs to be exposed in order for you to work on it. This foil - tissue - foil wrapping is ment to protect your phone from melting and damage while reflowing the solder on the flexi cable. If you have no experience in reflowing solder, DO NOT ATTEMPT THIS!!! you'll end up melting the cable and you'll need to take the glass off the front screen to replace the touch sensor unit. Again DO NOT ATTEMPT THIS!!! if you have any doubts.

I'm posting this to help, as I've read through a butt load of information on this fault and have not come across any mention of a bad solder joint on the flexi cable. Hopefully this will help someone fix their phone.

Hi Guys, i'm new to this android stuff & looking to learn 'how to' from this good forum.

I purchased a used S4 i9505 and the Touchkeys don't work. It's running stock android 5.01.

It looks like it may have had the screen replaced before i got it?

I have opened it up and the softkey chip no reads 0075

In the *#2663# screen the firmware for phones touchkeys is :0x12. Parts FW is : 0xfa

Hence it does not 'update' .... Or work .... FW is higher on Part than phone!

So ...... i have read some and am learning about this problem.

So my thoughts & questions are?

1. The Touchkey ribbon has GT-i9500 part no on it .... is it the wrong part for GT-i9505?

2. Will the odin/twrp flashing #134 with 4.7 work to force a downgrade FW on this chip?

3. Will an Android OS upgrade to 6.01 also upgrade this FW to get the Touchkeys working

4. What size SD card is needed to to this flash stuff & does it need to be blank?

I was thinking to use this phone 'to have a play' at upgrading to Android 6 & custom roms etc anyway

Your Experienced advice is greatly welcomed

Thanks in advance :) :good:
[Galaxy S 4 Q&A, Help & Troubleshooting] luckysoul777:
Sharing an experience I just went through in the last few days. My S4 (SGH-I337M) recently died. I337M (Canadian) is very similar to I337 (AT&T) except the former has UNLOCKED bootloader. Since I can't find an I337M mainboard without buying a "new" old phone, I ended up dropping in a GT-I9505 mainboard since they are supposed to be interchangeable. Most functions do work EXCEPT the back/ menu buttons. It turns out that the USB charging flex cable is *NOT* interchangeable. Since I changed the mainboard, I must use an I9505 charging flex cable too. If you wonder why a charging cable is even related to the back/menu buttons, it is due to the back/ menu button cable *NOT* connected to the mainboard directly. Instead, it connects with the USB charging flex cable first. The USB cable performs the "last mile" signal processing/transmission for the back/menu buttons!

With the I9505 USB flex cable, my back/ menu buttons worked intermittently. Previously with the I337M cable, these 2 buttons were completely dead. Upon further research, I stumbled on the Albe95_S6_Full_PORT_4-7b.zip fix and now everything works perfectly! No. you are not stuck with this ROM. After applying the fix, I am now back on the stock ROM.

Hi All.

I've read, and dug, and tried, and wasted so many hours on this.

I have a fair few of these S4's stuck in a drawer, so wanted to put them to some use.

They all have had screen swaps at some time i think, all were working fine, till the last OTA update that just buckled the soft keys.

I've followed post #134, and all the other recommended ones,

Is there an agreed solution to this for bringing back the soft keys?

i'm properly lost on this now.

When you have a ROM with 4files+PIT, you have to put each of them on the right Odin field (including PIT), and then flash with Re-Partition TICKED. That is: you have to use all the 4 files and PIT, on the right Odin fields. And Re-Partition TICKED this time.

Thats a Jelly Bean (Gummy Bear) 4.2.2 one!!

Give it a try, but I think that we will have the same problem: Touch Keys FW 0x12 (the faulty one, it seems) inside the chip, and flashing process not replacing it with the one inside the ROM.

I think that our conclusions are that we have to find a ROM with a Touch Keys FW newer (higher) than 0x12. Or only the FW itself, and a way to flash it, ofc.
