Would this work the same way with Lithium 7 as well? Also, in the flash tool do you set it to "format all + download", and uncheck the userdata partition, or just "download" mode, and uncheck the userdata partition?
To Install T-ROM 2.3, you have to format all + download but If you want to update T-ROM 2.2 or something, you have to download only and uncheck the userdata.img

I was going to host a custom rom but the problem Is when I added & removed some APKs and edited the build.prop, It was stuck on the boot logo and the bootanimation didn't work, so I kinda need a tutorial how to edit an android system.img
I have T-ROM 2.3 on my Timmkoo right now and It works the same as T-ROM 2.2
Look in the /pictures folder in filemanager or (if you use adb) /system/media/primary/wallpapers I added custom Wallpapers that I personally shoot.(Thanks @NoahDomingues for editing them : ) ) That's the only difference between 2.3 and 2.2

    That is interesting. It might be that there was a first gen version that had the 4.4.2 version, but when they re-released the all the Timmkoos (Q5, Q3E) they might have also re-released the Q8. (Just a thought.)
    I certainly think that's possible, the timeline is a bit confusing though

    **PLEASE WATCH THIS THREAD AS THERE ARE MANY IMPORTANT UPDATES TO BE RELEASED IN THE NEAR FUTURE**

    How to install apps (APKs) on Timmkoo devices (Q5 & Q3E):

    1) Download SP Flash Tool on your computer: https://www.mediafire.com/folder/jl2a4r8y9af8j/SP+Flash+Tool

    2) Download LithiumOS ROM/firmware and extract it on your computer (there should be four files).

    3) Flash the Lithium firmware to the device, using this guide by @Munk.3: https://xdaforums.com/t/tmmkoo-q5-q...dates-downloads-first-release-1-5-24.4643981/

    DOWNLOAD LINKS AT BOTTOM OF PAGE!!!

    4) Power on the device (this may take up to two minutes, longer in some cases)

    5) Obtain the APKs of the apps you would like to install. You can either do this on your Timmkoo, or on another device and copy the APKs to your Timmkoo Internal Storage/SD Card (if applicable). Although not necessary, I recommend you rename these files - for example, if an APK you downloaded was named "Chrome_81.1_arm_(apkdownload.com).apk" or something, I would recommend you rename it to just "Chrome.apk" for simplicity. Also, check that your APKs are compatible with your device.*

    6) Launch the "Root Explorer" app on your Timmkoo. Locate the desired APK files on your device, and copy them (tap and hold file(s) > Copy). Switch to the other tab, and navigate to Root > data > app (/data/app) - and paste the files (tap the circular "Copy Here" button in the bottom right corner). When prompted for root access after tapping "Copy Here", tap "Grant" to allow Root Explorer to copy to the /data/app directory. Select the newly-copied APKs (tap and hold to select) then tap the "More" menu icon (three dots, in the top right corner), then Permissions, then in the "ENTER OCTAL" field, enter "644" (or "0644" if 4 digits are available).

    7) (OPTIONAL) Reboot your TImmkoo device. Usually, after copying your APK files to /data/app, their icons will appear on your device’s home screen shortly after. However, sometimes they do not appear immediately, or experience issues when launching. In such rare cases, rebooting your device is required - I usually choose to do this anyway after installing new apps, just to avoid needing to do it later.

    8) Enjoy your new apps!



    *Ensuring compatibility of APKs: when searching for APKs to download, make sure to find a version of the desired app compatible with Android 4.4.2 (KitKat) - this is usually denoted on APK download sites by "Min SDK version: 4.4.2 KitKat (API 19)" or similar). APPS FOR NEWER ANDROID VERSIONS THAN THIS WILL NOT WORK. Usually (in nearly all cases), if an app is compatible with Android 4.4.2 will install with no issues on the Timmkoo. However, occasionally apps will be listed as compatible with Android 4.4.2 yet crash when launching on the Timmkoo, even after setting its permissions to 644 (if an app crashes, MAKE SURE you have set the correct permissions - 644 - and if this still doesn’t work, set them to 777, reboot the device and try launching the app again. When this happens, you need to find a version of the app older than the one you have found - when an app crashes, older versions of the same app work 90% of the time.

    Here is my recommendation for finding a suitable older version of the same app: navigate to an APK download site, such as APKMirror, APKCombo or UpToDown. Find the page of the app you would like to install. Then navigate to "All versions", "Older versions" or similar. Then scroll down (you may need to navigate through several pages) until you start seeing versions compatible with Android 4.4.2. Once you’ve found one, check that there are no prior versions of the same app that have a minimum Android version higher than 4.4.2. If there is, the version you are looking at probably is not compatible with 4.4.2 (even though it says it is). Instead, keep scrolling through until you find a version of the app compatible with 4.4.2, with no prior versions requiring a higher Android version.

    If you follow this and your selected app version still crashes, then your best option is to conduct a web search for "latest version of [app name] compatible with Android 4.4.2". If the app is moderately popular, you will likely find a correct answer - then search for an APK matching the version number you found online and install that.

    NOTE: A good, easy way to test an app’s compatibility is to try opening the APK on the device. If the app icon and name show up, and it asks you "Do you want to install this app" - then the app is likely to be compatible (not definitely, but likely). However, if instead you get an error message saying "Unable to parse the package" or similar, the app is definitely not compatible and you need to find another version.

    REMEMBER: Some apps just aren’t compatible, and won’t work on the TImmkoo no matter what you do - when this happens, I’m afraid there just really isn’t much you can do! (This is rare of course. And bear in mind that Android 4.4.2 is quite old now; many apps have been developed long after 4.4.2’s release (and end of support) - and are not compatible.

    Hey guys, here with a step by step how to do it through Moonreader.
    1- Go into MoonReader, open a file, any file
    2- Hold down on any word, and select the "More"option, and click Customize
    3- Set Dict. 1 to Other Installed Apps, choose any app
    4- Then, go the main Moonreader page, and swipe to the left, until you see the folder view, AKA My Files
    5- Click on the /, and create a new folder named data/data/com.flyersoft.moonreaderp
    6- This will bring you to the inside files of the app, find the folder named "shared_prefs", enter it and find the file named "dict.intent0", copy it to somewhere else that you can edit it, your phone, computer, etc., and change the first two lines of code to 1- com.mediatek.engineermode and the second line com.mediatek.engineermode.EngineerMode, LEAVE THE BOTTOM AS IS. Note- you can edit it using any text editor, just rename the file to dict.intent0, and transfer it back to your Timmkoo
    7- Next can be a bit complicated, but follow along closely and it should work, put your new dict.intent0 file, in any folder on your device. Now, go back into Moonreader files, go back to /, find your file, I like going through "storage/emulated/0", copy your edited file, go back to /, again create a folder called data/data/com.flyersoft.moonreaderp, and go in to shared_prefs, delete the old dict.intent0 file, and paste your new one
    8- Now, go back to your file, hold down on a word, and tap on Dict, you should see engineer mode, swipe until you're in Logging and Debugging, and open MTKLogger
    9- Click the Settings on the top right, go into Run Command, now make sure you have your APK file ready, I like putting them in an easy location, such as Alarms, on the Device Storage.
    10- When your in the Run Command Window, put in the following text - cp "path/to/apk.apk" "/data/app/yourapp.apk"
    chmod 644 "/data/app/yourapp.apk" - I will give an example, I always put my apk's in ALarms, and put in the following command, cp /storage/emulated/0/Alarms/Filename.apk /data/app/Filename.apk
    chmod 644 /data/app/Filename.apk This can work in any folder you choose, but for your ease of access, use a simple one, like alarms, or create your own called APK or whatever. NOTE, keep your filenames short, like numbers or letters, if not you make mistakes while entering the name in MTKLogger
    11- Click OK, go back to the main MTKLogger, and click the start button, then go back into Settings , click Run Command, click OK, wait a minute and your app should install and pop up on your screen!
    That should be it, LMK if you have any questions, I found this method very easy to do once you get used to it.

APPS FOR NEWER ANDROID VERSIONS THAN THIS WILL NOT WORK. Usually (in nearly all cases), if an app is compatible with Android 4.4.2 will install with no issues on the Timmkoo. However, occasionally apps will be listed as compatible with Android 4.4.2 yet crash when launching on the Timmkoo, even after setting its permissions to 644 (if an app crashes, MAKE SURE you have set the correct permissions - 644 - and if this still doesn’t work, set them to 777, reboot the device and try launching the app again. When this happens, you need to find a version of the app older than the one you have found - when an app crashes, older versions of the same app work 90% of the time.

    Here is my recommendation for finding a suitable older version of the same app: navigate to an APK download site, such as APKMirror, APKCombo or UpToDown. Find the page of the app you would like to install. Then navigate to "All versions", "Older versions" or similar. Then scroll down (you may need to navigate through several pages) until you start seeing versions compatible with Android 4.4.2. Once you’ve found one, check that there are no prior versions of the same app that have a minimum Android version higher than 4.4.2. If there is, the version you are looking at probably is not compatible with 4.4.2 (even though it says it is). Instead, keep scrolling through until you find a version of the app compatible with 4.4.2, with no prior versions requiring a higher Android version.

    Si vous suivez cela et que la version de votre application sélectionnée se bloque toujours, votre meilleure option est de rechercher sur le Web la dernière version de "[nom de l'application] compatible avec Android 4.4.2". Si l'application est modérément populaire, vous trouverez probablement une réponse correcte - puis recherchez un APK correspondant au numéro de version que vous avez trouvé en ligne et installez-le.

    NOTE: Un bon moyen facile de tester la compatibilité d'une app’s est d'essayer d'ouvrir l'APK sur l'appareil. Si l'icône et le nom de l'application apparaissent et qu'il vous demande "Voulez-vous installer cette application" - alors l'application est susceptible d'être compatible (pas définitivement, mais probablement). Cependant, si au lieu de cela vous obtenez un message d'erreur disant "Impossible d'analyser le paquet" ou similaire, l'application n'est certainement pas compatible et vous devez trouver une autre version.

    RAPPELEZ-VOUS: Certaines applications sont tout simplement compatibles avec’t, et won’t fonctionnent sur le TImmkoo, peu importe ce que vous faites - quand cela se produit, I’s redout there just really is’t much you can do! (C'est rare bien sûr. Et gardez à l'esprit qu'Android 4.4.2 est assez vieux maintenant; de nombreuses applications ont été développées longtemps après la sortie de 4.4.2’s (et la fin du support) - et ne sont pas compatibles.
