[Samsung Galaxy S7 Questions and Answers] gx123:
Hi everyone, I am trying to build a custom kernel and repack boot.img in order to apply a custom driver on a Samsung Galaxy S7.

Galaxy model :

SM-G930F
firmware version: G930FXXU8ETI2 (taken from Samfw.com)

I've flashed with Odin, then installed twrp, made a backup and extracted boot from twrp backup (boot.emmc.win file, renamed boot.img).

Obtained the boot.img, I have downloaded the following github repo:

https://github.com/xiaolu/mkbootimg_tools.git

that helped me to unpack the boot.img.

By Unpacking boot.img i obtain ramdisk + kernel file:

mkboot boot.img boot
-rw-rw-r-- 1 gx123 754K giu 9 10:02 dt.img
-rw-rw-r-- 1 gx123 254 giu 9 10:02 img_info
-rw-rw-r-- 1 gx123 32M giu 9 10:02 kernel
drwxrwxr-x 16 gx123 4,0K giu 9 10:12 ramdisk
-rw-rw-r-- 1 gx1 4,6M giu 9 10:02 ramdisk.packed

Now, I have tried to change ramdisk section (add a new file in ramdisk section) and pack with the following command:

mkboot boot packed-boot.img

Then I upload the packed-boot.img file in device and send "Install Image" with twrp and it works: the boot starts and new files are added in ramdisk.

But I sould like to change the kernel ...

I have downloaded several kernels source code from github, for example from official OpenSource Samsung (model G930FXXU8ETI2) and from github (i.e. https://github.com/ThunderStorms21th/S7-Linux-3.18.140.git) .

Now, If I try to change the kernel, pack the boot.img (command: mkboot boot newboot.img) , store it in device and flash it with twrp, it goes in a bootloop.

I have attached last_kmsg.txt after restart the device in recovery mode and run TWRP.

Do you know if there is some other steps to follow? Am i wrong something? Is there some modification in dtb.img to be perform?

Thank you very much in advance.

Thanks anyway.

Due to move to the HTC Raphael, there's a beautifull and very unique TyTN II for sale now... http://cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&rd=1&item=320302813398&ssPageName=STRK:MESE:IT&ih=011

The starting price is high...i know...but this is something very special...and it doesn't HAVE to go... I personally 'pimped' this Kaiser, and it's in perfect condition, comes with a Dutty WM6.1 release, and with the spare parts to make it black again (and a brandnew slider-mechanism, for if this one wears out).

Hi, I'm trying to install LineageOS on my Zuk Z2 without Gapps because I want to use microG. However, if I don't install Gapps the setup wizard on first launch of LineageOS will crash each time, and if I do install Gapps and then try and remove it afterwards the system hangs at boot time. Based on what I've read it is possible to install LineageOS without Gapps

[Realme 5 Pro ROMs, Kernels, Recoveries, & Other De] PAXILE:
If there was at least one current up to date video or set of instructions for installing twrp, custom roms then it would it much easier for us noobs, but there isn't. All the videos are old, out of date or lack the full instructions and things go wrong after you follow them. It's sad I do like installing custom roms but I have a lot of difficulty doing so with this particular phone because they just don't work properly and this is coming from color os too.

[Touch Pro, Fuze General] d96mbe:
Do you have problems with bad speaker sound quality when making calls?

When making calls there is a crunching/scratching sound from the front speaker. It sounds as if it's cracked or as if the cable is poorly fitted or exposed to interference of some kind.

Since this is my second Touch Pro, the first had the same problem and considered DOA, I'm wondering if you're experiencing the samt problem.

BR / Magnus

Edit: speaker -> front speaker
[Touch Pro, Fuze General] lloydcody:
Hrm..

I just RMA'd my TP 'coz of this problem (literally just got back from the post office). So are you saying that your new one also has this problem?

Still no update from Expansys UK (the retailer) despite having sent it back to them a week ago. I've called and emailed with no response. All I ever get is "we currently have no update on the status of your return other than we received it".

VERY poor service. I didn't expect this kind of service from them. I will definitely be avoiding them in the future. I have requested a refund and contract disconnection now as this is ridiculous. I doubt I'll get a response tho....

Just got a message that my third device is sent. Meaning the two previous was accepted as DOA... We'll see if the new phone is working better.
[Touch Pro, Fuze General] DDBrain:
Hi Guys,

Maybe I'm stupid, but could you explain the bad speaker means the receiver which is in front of phone, or the speaker in back of phone?
[Touch Pro, Fuze General] lloydcody:
My bad speaker was the loudspeaker at the back of the phone. Although the volume is poor on the earpiece speaker (but this is normal at least). I think HTC devices have gone downhill these days. I came to the TP from a Universal which I've used for over 2.5 years! And it still has better sound quality etc. Shame Expansys are messing me around too. Still no response from them...

Hey guys,

[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] stavrosbin:
So I was checking the specs for the phone before buying and everybody says that it doesn't officially support wireless charging. So I wanted to know if somebody has managed to make wireless charging work. I have seen a couple of videos for phones that don't support it either charging wirelessly with NFC. Sorry for the noob question, just wanted to make sure because I haven't used wireless charging before.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] laid1995:
I don't think you can. The hardware isn't set up for wireless charging. I'd recommend not trying things that could put your phone in danger.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] CHGICEMAN:
Buddy, if the specification says that it doesn't work, then it doesn't work. No matter who made which videos. There are external wireless charging options that are placed under the TPU bumper, but the USB-C port is always blocked.

Some semi-wireless, though unsure about the safety or usefulness.

It's not got a wireless charging coil so the answer is no wireless charging

Hi, i own S95 Doogee phone. After installing GSI custom rom (i tried Havoc, Lineage,Pixel exp) screen keep on flickering. In programes options i can turn GPU drawing as allways on and flickering stops. Problem is that at every restart and randomly this seting turns it self off . Any solution to get it working as it should ?

P.S. Flickering +discoloration occurs when something is being rendered on the screen.

OK, I figured it out,

Phh Treble Settings -> Misc features -> Display -> Disable HW Overlay

For those who use another audio player than the default manilla audio manager. Do some noticed like me that when a song of the manilla player is launch, it increases the general volume. Do a little test : play a song with pocket player for example then minimize it and play a song from the manilla player. Just wait for this song to start then stop it. You'll see that the volume has increased. There is the same phenomenon when you disable audio booster unplug the cable, click "retry" then enable it again. Is there a way to have this increase of the overall sound without having to do that? I remember with the firsts diamond, to have a decent sound we had to do the "audiobooster unplug then replug tweak" then we no longer need it to have decent sound but to have increase of sound
[General Questions and Answers] jonnyprogamer:
Update: i went to a local store and he said that the tablet doesn't have the bootloader so rip i guess
[General Questions and Answers] :
Every Android device has a bootloader, unless it gets removed by user: without a bootloader Android OS couldn't get started.
[General Questions and Answers] jonnyprogamer:
hi and thanks for the reply, well then do you know any way i can access it? because the guy at the shop said that my tablet was too old that it didn't have one, i tried going into the bootloader with adb using the computer and also using an app on the tablet itself, both of those method don't work and they just boot normal android.
[General Questions and Answers] :
ADB deals with Android OS, whereas FastBoot deals with device's bootloader: totally different softwares.

To operate on its bootloader, device's bootloader must get made accessible, known as get unlocked: this gets enabled within Android -> Settings -> Developer options.

FYI: As with Android, recovery refers to the dedicated, bootable partition that has the recovery console installed from which you can perform specific tasks.
[General Questions and Answers] jonnyprogamer:
hi, what i meant is i tried to type adb reboot bootloader into the cmd and it booted to normal android, now im going to turn on the tablet and go into the developer option to check if there is a bootloader thing to enable, so how do i unlock it? i go to the developer option and then what do i need to press?
[General Questions and Answers] jonnyprogamer:
hi, unfortunately i didn't find any option that was talking about the OEM or the bootloader in the developer settings, i could try to attach the screenshots of all the developer settings i have, but i was also thinking that maybe the root is causing issues?
[General Questions and Answers] :
If I were you I would completely reset the tablet

adb devices
adb reboot sideload
adb sideload <STOCK-ROM-ZIP-FILE>
[General Questions and Answers] jonnyprogamer:
ok the stockrom is on the site only problem is that well it's 404 not found, but i will try archive.org, also should i unroot first?
[General Questions and Answers] jonnyprogamer:
hi, uhm the stock firmware isn't archived on wayback machine

http://www.start-tablet.it/ftp/START-LOGO_V1.5.1_20130107.zip

also i never changed the rom, i just rooted the device a long time ago so maybe the un-root will fix stuff? if not how can i find the stock firmware?
[General Questions and Answers] jonnyprogamer:
Hi, it's me again, i know this is kinda old but since i have the same problem i will say it here, basically i gave up on this device in june of last year but now i want to try again, im still having the same issue (in recovery i see no menu, i only see the android logo with a red triangle, and yes i tried power button + volume down or up and even both, but none of this key combination made the menu show up) so im stuck and i don't know what to do, i unrooted the device to see if maybe it could affect anything but it didn't so i rooted again with kingroot.

I also have the cwm recovery made for this tablet but i can't flash it because i can't access the bootloader, i tried to boot with volume down, adb reboot bootloader, and even one app on android that reboots to bootloader if you have root (which i have), from what i found on the internet my bootloader should be unlocked because i was able to root, i also tried apps like flashify and rashr to flash the cwm recovery but they don't work, after i give them root access i tried to flash with Flashify and when i press the button to select the zip file it just hangs the application,

with Rashr it gives "Failed Execute".

I just want to flash the CWM recovery because i want to sideload the Google Apps, but since i can't find a way to go into the bootloader im trying to do it from adb shell, i also tried "flash_image recovery /path/to/recovery/" but it doesn't find the flash image command.

I Found a way im on CWM now, i used

dd if=/sdcard/customrecovery.img of=/dev/block/mtdblock8

and it flashed the recovery, only problem is that only the power button works the volume up/down do not

buttons weren't working because of bad recovery.img, fixed.
[General Questions and Answers] jonnyprogamer:
mhm, well i followed the guide in that youtube video correctly, well at least im in the recovery menu if i remember there is a way to sideload GAPPS from pc now that i have CWM.

Maybe i made the CWM incorrectly, do you know how to make it work completely?
[General Questions and Answers] notnoelchannel:
I can't sadly.maybe the drivers are wrong?
[General Questions and Answers] jonnyprogamer:
Ok so after going 1 year of google history i was able to find on how i made this custom CWM for my tablet,

basically i followed the youtube video (linked in my first message of this thread) and got these files:

The video said to get a recovery from the same chipset, which i did:

CWM WM8850 NSFAT-RC2 - Download - 4shared

Download CWM WM8850 NSFAT-RC2 at 4shared free online storage service

www.4shared.com

Then my stock recovery, which i did:

recovery.img - AnonFiles

anonfiles.com

and i just followed the guide (1 year ago) and it seems to be working, now im thinking maybe volume up down do not work because my stock recovery didn't have those programmed?

for me it makes sense because in the stock recovery i wasn't able to make the menu appear even if i spammed volume up/down and after 1 min it rebooted back to android, when i checked my stock recovery log it said something like no input in 1 min, rebooting...

Even if i tried to use volume up/down, so maybe the stock recovery didn't have the volume buttons programmed.

So how do i make a good recovery that works for my device?

Can i just flash the Generic CWM_WM8850 without following the guide on that video?
[General Questions and Answers] jonnyprogamer:
I think the problem is that my stock recovery didn't have the volume buttons programmed (maybe to block people from using the recovery since it is a chinese tablet)

so after re-packing the generic WM recovery with mine it removed volume up/down functions, so do you think i can flash the generic WM8850 recovery i linked without following the Youtube guide?
[General Questions and Answers] jonnyprogamer:
YES I DID IT, i flashed the generic CWM for this Chipset and now volume buttons works! I sideloaded GAPPS for android 4.0 :)
[General Questions and Answers] notnoelchannel:
Congrats man! Do you want a mod to close this thread because this problem has been solved by yourself?
[General Questions and Answers] jonnyprogamer:
Ok, but first i wanted to say some stuff, first thank you very much for helping me, without your help i probably would have probably lost hope in this device lol, then i wanted to ask where i could post another thread

(because im still not very good at navigating trough this forum), this time about fixing youtube.

Because i found this video on Youtube on how to fix it on android 4.0:

But i wanted to know if maybe there is a way to change the version number of the apk to spoof the version and make it connect, because doing that every time is painfull lol.
[General Questions and Answers] notnoelchannel:
You can post threads everywhere by clicking "Post thread" like you did here :D

By the way, you can make your own ROM for this tablet, you just have to make device tree, vendor tree (which is pretty easy i guess), kernel tree. I can help you with that if you want to make a ROM :)

I can make you a spoofed youtube apk, here it is (And yes, it is possible to change the android version):
[General Questions and Answers] jonnyprogamer:
Hi, thanks, can you explain to me on how to make a spoofed apk?

1: i want to know how you made this new ver (13.x) work on android 4.0

2: i want to know how to edit the version number of an old version of youtube (like 10.x shown in the video) to bypass the update screen on that version without having to always clear google play services data, etc...
[General Questions and Answers] jonnyprogamer:
Thanks, i also backed up the Stock ROM after sideloading GAPPS, used both the "Backup" function in CWM and "Backup-Image" so i have a backup folder and a zip file, it should have all the stock rom files right?
[General Questions and Answers] notnoelchannel:
I don't use CWM, but yes, it should have all the rom files
