[Android Q&A, Help & Troubleshooting] Raiz:
You need first to go to /system/priv-app/Settings and get the settings apk

Copy it and paste it to a folder like download or documents.

Take your PC and install Apktool and Java JDK ( the installation of those is pretty easy , search on google if you have some difficulties )

Plug your device on your PC and transfer the settings apk on the Apktool folder.

Rename the apk file !

Open a command prompt on this folder ( the Apktool one) and enter this command

java -jar apktool.jar d Settings.apk

Open the Settings folder created by Apktool when decompiling and go to /res/values and open colors.xml ( with with a text editor , I advice notepad++ or Grant)

From there follow my tutorial to find the right color :

https://xdaforums.com/android/themes/guide-how-to-theme-android-app-t3777101

Use only the part II-1 , modifying system file is different from modifying a simple app .

Once you identified the hex code of the background color , search for it with the search tool of notepad++ (Ctrl+F)

If you see more than one match , try to figure out which one is the good one , make some test )

And now you should recompile the settings.apk with this command :

java -jar apktool.jar b Settings -c

The "-c" is really important , don't forget it !

Don't transfer the modified settings apk on your phone , with a root file manager rename the old name "settings.apk" with the name "settings.apk.bak" in the /system/priv-app/Settings folder.

Place in this folder the modified APK and reboot your device.

If the settings app Force close , you may have missed something , good luck :svetius:.

but could you see my photo? I hope you understand that the background color of settings menu. ok, I understand, but in case of problem, to use bakcup of this file for restoring, must i restore before tablet starts in system recovery menu? (like windows pc bios)?
[Android Q&A, Help & Troubleshooting] Raiz:
I don't see the photo you posted .

To recover the settings APK in case of FC, just use your root file manager to delete the modified settings apk in the /system/priv-app/Settings folder , and rename the "settings.apk.bak to "settings.apk" and reboot :svetius:
[Android Q&A, Help & Troubleshooting] lovestudio:
ok, i know this. i put the photo link above in1 st post, look at it, and if your manual is regarding this color, then, do not reply. thanks.
[Android Q&A, Help & Troubleshooting] lovestudio:
I did it, original settings.apk had 9.80 mb, then after this thing, there in folder called framework appeared compiled file of only 1.60 mb.

Also errors:

all was done correctly 10 times, result is the same. By the way, there was also settings.odex near it in tablet (if needed).

the colors file is very little:

<?xml version="1.0" encoding="utf-8"?>

<resources>

<color name="black">#9b4b96</color> this I changed

<color name="red">#ffff0000</color>

<color name="memory_used">#9b4b96</color> and this I changed

<color name="memory_avail">#ff333333</color>

<color name="memory_apps_usage">#ff77831a</color>

and some more lines
[Android Q&A, Help & Troubleshooting] Raiz:
Oh yes ,I forgot to talk about deodexing

Go and download on your PC a tool for deodexing , called Baksmali from here: https://bitbucket.org/JesusFreke/smali/downloads/

(Take the lastest one )

Create a folder called Baksmali (next to the Apktool folder) and put the downloaded file in it , rename the file to baksmali.jar.

In the /system/priv-app/Settings directory , copy the settings.odex , paste it to the Download folder and transfer it on your PC in the Baksmali folder .

Then go on your device again , go to /system/framework/ and copy the arm folder ( if your phone is arm) or arm64 (if your phone is arm64) and paste it to your download folder

To know which arch your device run , install CPU-Z from Google play and search for it in the app ( in the CPU section)

Then transfer the arm/arm64 folder CONTENT to the Baksmali folder on your PC.

(Only transfer the content of the folder )

Now you have all the elements , open a command prompt in the Baksmali folder and enter this command

java -jar baksmali.jar deodex settings.odex -l

A folder called out will appear , copy everything in it , go to the Settings folder into the Apktool folder (the folder created when you decompiled the settings.apk), create a folder called smali and paste everything there .

Then retry the tutorial I gave you in my last post , good luck.
[Android Q&A, Help & Troubleshooting] lovestudio:
ok, in /system/framework/ there is no arm folder, only many files with jar and odex extensions. first 2 files are called: am.jar and am. odex

and one folder [MENTION=726966]Web[/MENTION]view with many files of .pak extension@. Though I know, that tablet has arm architechture, cos I have kernel tunnner app installed. So should I deal without this folder?
[Android Q&A, Help & Troubleshooting] Raiz:
Ok , if you haven't those folder , take every jar file in the framework folder instead of those in the arm/arm64 folder.

Let me know if it worked.
[Android Q&A, Help & Troubleshooting] lovestudio:
sorry i was wrong, i have retried, the same result as before with only apktool folder working.
[Android Q&A, Help & Troubleshooting] Raiz:
Could you precise what worked and what didn't ?
[Android Q&A, Help & Troubleshooting] lovestudio:
all worked what you told me to do, but the result of final step of decompiling settings.apk with 1 tutorial is the same: as here: https://xdaforums.com/showpost.php?p=77175345&postcount=6
[Android Q&A, Help & Troubleshooting] Raiz:
It looks like it's a framework issue.

Go on your phone to /system/framework , find framework-res.apk and copy and paste it to your download folder , then transfer it to your Apktool folder ( to go faster with this step , I'll say transfer instead of copying and pasting )

Then go to /System/priv-app/SystemUI and transfer SystemUI.apk to your Apktool folder.

Open a command prompt on your Apktool folder and and write this code :

java -jar apktool.jar if framework-res.apk

java -jar apktool.jar if SystemUI.apk

Then retry my tutorial once again
[Android Q&A, Help & Troubleshooting] lovestudio:
you have a patience with old android kitkat version, ok, I will try, I think tutorial only 1st one, without 2 tutorial.
[Android Q&A, Help & Troubleshooting] Raiz:
Don't worry , I'm here for that :highfive:
[Android Q&A, Help & Troubleshooting] Raiz:
Try to enter this command:

java -jar apktool.jar empty-framework-dir

And then enter this command :

java -jar apktool.jar if framework-res.apk

And retry the tutorial 1 (and the one with smali the folder)
[Android Q&A, Help & Troubleshooting] lovestudio:
ok, done:

C:\Users\Admin\AppData\Local\apktool>
I: Using Apktool 2.3.3
I: Checking whether sources has chang
I: Smaling smali folder into classes.
Settings\smali\android\support\v13\ap
0] no viable alternative at input ''
Could not smali file: android/support
ali

C:\Users\Admin\AppData\Local\apktool>

the result is not done as you see. No use to deal with these framework smali created 3 folders with too many file, cos I notices when decompiling settings.apk, in smali folder already created same 3 folder with almost every 3294 files. But I tried, and nothing.
[Android Q&A, Help & Troubleshooting] Raiz:
Ok , so retry without baksmaling odex etc , just do the 1st tutorial and the tutorial with the "empty-framework-dir" command.
[Android Q&A, Help & Troubleshooting] lovestudio:
empty-framework-dir just remove previous file 1.apk from folder of framework nothing changes. i know this.
[Android Q&A, Help & Troubleshooting] Raiz:
Yes , but it could debug some situation.

Let me know if it's worked ?
[Android Q&A, Help & Troubleshooting] lovestudio:
but i have tried it already yesterday, and just explained , that i knew what it did in generaly.

what do you think, probably i should try this post? https://xdaforums.com/galaxy-note-2/themes-apps/how-to-change-settings-background-image-t2849952

though it is not the sae,but similar, but there there is no clarifying, cos 3 variants offered, and my phone is not samsung. if you think, that i should, copy me here, what vaRIANT i shoul try from this article. thank you.

[Android Q&A, Help & Troubleshooting] lovestudio:
listen to me, the question is partly solved, the problem was, before compiling again, I had to copy original resources file. Found on youtube by xxxSuperserieSxxx xda gangsta video - [YOUTUBE]https://www.youtube.com/watch?v=HHm2bKR6uLk[/YOUTUBE]

but the problem is i cannot copy to test this file to system/framework folder. I used 10 commanders explorers with root, game them su, and then when copying, they asked, if I wanted to make ext4 folder...... R W , I gave yes, result ok, and then message: the copying failed. I am easily rooted, every root app works always good. Any thoughts how to copy, cos youtube and google manual say nothing about this problem. thanks.

have you rooted you A37fw?
[Oppo A37 Guides, News, & Discussion] didotb:
I'm sure as hell I have a37fw with ColorOS 3.0.0

but there are quite a lot of things that seemed to be okay with yours, but not mine.

First of all, the oppo tool v1.6.5 bootloader unlock didn't worked.. I found someone saying try 1.6.3. and it worked..

but I guess that lead to another problem.

all alleged "a37fw TWRP 3.1.1.0 recovery" never flashed. it just skips the recovery and goes straight to system. (it vibrates though and shows the oppo logo for a brief moment, then restarting back to system)

(I guess this one's my fault) I tried overwriting kingroot to super-sume without TWRP (since it didn't look like it needed TWRP)

and now it's just here beside me, being used as a hand warmer.. stuck again.. 3rd time in bootloop.

P.S. Yes the original unit box, and the system info settings do tell it's an "A37FW" with the latest 17xx

I read once about downgrading to 16xx is enough, but never found any binaries that would let me

Rom update @ Aug 23, 2018: ver. 180817

As of August 23, 2018

Oppo pushed a new update to a37fw stock rom

I believe this one update enforces anti-rooting to a37fw devices. For this happened 2 days after I serviced my device because I hard bricked it (even the qualcomm chip, since it gives firehose NOP errors which up to now doesn't have any fix, nor known causes) after trying to find a way to root it.

I do not know if this was really the cause, but the fact that the personnel took note of it on a paper, along with some information, which they send back to Oppo HQ for data processing. Is proof enough that this was the case.

From my first reply to this thread, I mentioned I wasn't able to successfully unlock bootloader, and that I hard bricked it. To the point where only QFIL can recover it. I noticed that a chinese website was hosting a file that could still recover data from the broken device. And I noticed when I tried it, it had info that bootloader was unlocked but untampered. So I doubt that using the older oppo tools version would really do unlock the bootloader successfully.

Yes, but some devices cannot continue to unlocking bootloader for some reason. No one knows why

Are you new to Updating?

OTA simply means Over The Air

it is a kind of update where your device gets it from the internet.

Much like the Windows10 updates, but this time it's android.

thanks again and again my love to you :)

UPDATE 2 :

using root checker to check root manny times after every step.. sometimes it says: NO ROOT!

but what happend is at the step of replacing kinguser by super user i opend super user app and clicked on that button..it removed kinguser and get the root permision. EVERY THING IS OKAY NOW.

BUT i restart my device and what iam facing now is HANG ON LOGO!!!

i tried every thing.. off device and open again manny times still stuck on logo!

tring to login recovery mode by pressing VOLUM DOWN AND POWER BUTTON but its restart manny times !
