Hi there, I am new to the Embedded Systems environment and I need some help. I am the "Tech Guy" for this Gas Station Restaurant Hybrid down the street from where I live and they have two Datalogic Scorpio X3 Handheld Scanners Running Embedded Handheld 6.5 and they are looking for some new software for the kitchen because they are leaving the Hot Stuff Franchise. The application they are using is going to be shut down at the end of their contract with Hot Stuff. That application is a Scan and Print type of app that will print off barcodes as that are scanned. I am currently looking at a company right now called Brady Systems and they have exactly what I am looking for but they would have to get a whole new system, including the printer, scanner, and they would have to be paying a boat load more money just for the application. Can someone please help me find an application like that that will run on Embedded Handheld 6.5.

Okay, I got an Oukitel C21 and at one time forgot my password. I gave someone to flash the phone and ever since, the battery drains soooo fast and charges a lot slower.
I had the battery changed to an Infinix battery because I couldn't get one for Oukitel C21 quickly at where I am and it still is the same.
What did I do wrong and how can I correct it?

A battery replacement will never work the same from a different device, unless it is from a rebranded one.
At software level, what you can do is, formatting data and flashing the newer official ROM for it.

Oh, I forgot to add that at one time, while I was locked out of my phone, I tried formatting it and at a number of times, I pressed "Clear EMMC" thinking it would help the situation.
Could that be the problem?

I have a Lenovo TB-X304L and I installed a custom ROM on it a few months ago. Everything was working perfectly except for some bugs and some specific apps crashing. So I thought of flashing the stock firmware to go back to the original ROM. I didn't take a backup when I installed the ROM. I used Lenovo's "Rescue and Smart assistant' to download and flash the right firmware for my tablet. I was able to flash it successfully and all but when I tried to boot it up. It was just stuck on the Lenovo screen for a minute or two and then turned off. I tried turning it on several times but every time it would turn off after staying on the 'Lenovo screen' for a minute or two. I even tried booting into the (stock) recovery and factory resetting it and also formatting the cache partition but nothing worked. I also noticed that the device's bootloader is locked and the TWRP recovery got removed. Now even if I want to flash a custom rom, I can't because to do so I need to turn on USB debugging and turn on OEM-unlock but I can't boot into the OS. I tried flashing in 2 times now but its always stuck on the boot screen. Please help me if there is anything I can do with this.

Thank you.

Device: Lenovo Tab 4 10 (TB-X304L)

I'm trying to learn how to attach a md5 and SIG file to a zip file.
The device I'm working with only accepts files that come with a zip, md5, and a zip sig

Probably. Replace the battery with the correct battery for your specific model number and then reflash your stock firmware.

By using APKtool to decompile the apk, then edit the apk then recompile the apk with the changes added then install the new apk on your device then reboot.

Has anyone tried rooting their Redmi 10C? Or install GSI?

Any comments on Redmi 10C is accepted, I can't find a dedicated forum for this device.

In regard to the GSI stuff, the procedure isn't different from flashing to other Qualcomm device, pay attention if your device has a super partition, if so, then search for "How to flash a GSI onto a device with dynamic super partition", you should need to merge the system image within the others images that are in the super partition.

In regard to root it, you should read this as reference https://forum.xda-developers.com/t/tutorial-magisk-on-gsi-on-devices-with-dynamic-partition.4311045/

    This is from 2016. Do you think is still valid?
    Re-read my post. I did NOT say that the thread I linked to was the ultimate or current guide. I advised to look at LOS as they had current guides.
    The XDA threads started a long time ago, but they are good if you get a problem along the way. ie the instructions in the OP are outdated
    I specifically said the OP instructions were outdated!


    Firstly I need some foundations to start moving forward. I would like to start by replicating one of the ROMs that I already know, are working under my device. Basically I want to start with the premise the if someone did it, I could do it again, before I venture in "new devices" into the unknown camp.
    And thats why I suggested reading the how to build LOS. They probably have the largest device coverage, and have instructions for each device. So if your device was "kirin"

    But if you look at the base GIT pages for a custom ROM they usually also have instructions on how to build, but not normally device specific or as thorough as LOS. Did i mention you better get comfortable with GIT...

    I think I could build from sources and all that without issues, but I don't really know where I must be touching and tweaking things to make things work. I have 0 knowledge about this topic.
    Im not sure how little you know about programming or how much you wish to modify the ROM, so thats like asking how long a piece of string is. READ! where to tweak is going to rely heavily on programming ability. oh, and READING

    What happened to rom development compared to 5 or 10 years ago? I figured thought that development would have increased over time. I thought it was just my device (OP9), just a few roms with very few likes on them, so I stopped in the pixel 6 / 6 pro forums, and there weren't any roms. Is xda dying?
    I used to compile ROMs for my previous devices (I think I built & published about 10+ ROMS for up to 4 device here on XDA). Its now becoming a LOT more difficult & time consuming. These are things that make the OS better, just more difficult to develop for. For example, the RO system partition, although much more secure and stable, it makes it a HUGE hassle if a dev wants to simply go into TWRP, modify/replace a file or two to test a concept. Actually, previously one could often simply modify the file on a rooted device, and sometimes not even have to reboot or flash. Also, even building a ROM is taking much more time (ie the build process) and more demanding on computer specs. So a dev needs bigger & better computers and drives and have to wait longer for the build to complete, only to find it fails at the last step, and then make the change and start the build again. ie the longer it takes can have an almost exponential effect. These are my roadblocks, others will have their reasons.

    I have it taken care of thanks for all the helpful advice and recommendations.
    I dont have or ever had the problem but it may help others if you post some info of how you sorted it.

    so basically "things" were simpler a few years ago?
    my guess (NOT a developer) would be about android 9?
    when would you say "roughly" that things changed mr. @DiamondJohn ?
    Yes, things were definitely simpler.

    I think it is very dependent on the device. ie hardware-software integration and r/o partitions etc etc I know Oreo was pretty easy for my devices, which were shipped originally with much older androids. And now my Pixel 4a is a big commitment to do my first attempt at a 12 build. From memory, my PC could pump out an oreo build from source in 1hr. Also from memory, I tried a Pie build, and that jumped to 1.5hrs. On a side, I personally think that the availability and functionality of TWRP for the device is a good "acid test". Note, there still isnt a stable and fully functional TWRP for my Pixel 4a. ITS A PIXEL DEVICE! People think if they can flash it, then its stable and fully functional. Its not the case. Having TWRP is different to a fully functional and usable TWRP. To put it into some perspective, TWRP used to take only 8 minutes to build for my device, compared to 1hr for a ROM.

    Just for another example of what I was talking about above, previously to change the boot animation was simply a case of copying a ZIP file to the system partition. Now, to do it properly requires a new build & flash of the whole ROM. It can be "half done" using magisk, but on my current Pixel 4a, it plays the old animation until after a forced warm reboot in the module, thus showing a few seconds of the stock animation, followed by a restart from the very start of the new animation.

    Thank you for your help:

    How did you flash TWRP? Are you sure you flashed permanently, or only booted to it?

    I install it with adb command "fastboot flash recovery twrp.img", i think the install is correct (also the phone brick again after the install)
    If you are in MM, then you should use these files, https://forum.xda-developers.com/t/ask-any-question-newbie-friendly.2259645/page-1592#post-87089841 not sure which process you did, in those days, some users pretend to bypass the official unlocking process, and just flashed a custom aboot file to bypass, AVB security, so it depends on what exactly you did,
    When you are saying, not able to flash anything through TWRP, then, isn't the option there? Can you upload some screenshot through TWRP´ main screen?

    I add 2 pictures, in picture 1 is the option "install" of twrp, as you can see the side bar is the lowest it can go and as you can see no files are show, only folders, in picture 2 i use the "file manager" option on "Advanced", here you can see the Magisk apk but of course i can't install from file manager.
    Did you navigate to where the file is? It looks like Magisk is in your SD card, not in your internal memory?
    Edit; I noticed you didn't change the Magisk file extension, so probably TWRP install menu won't find it.
    You can still use the ADB sideload feature to flash the file from your PC using TWRP.

    I read something about that, but i read a comment of someone wipping the info of the PC so i don't risk since i'm a noob.
    No, it's just other method to flash a file, also you can transfer or sideload the file to your Android device, then flashing it through your PC either using the ADB sideload or some TWRP scripts that is available through your CMD Windows PC (or Linux based)
    Device not booting may be, either, due to not formatting data or not flashing the vbmeta for your device or lastly, not flashing the DM verity disabler.

    Again, i'm a noob, i only apply the "monkey see, monkey do" after watching tutorials, i can't understand anything about this part, i mean, formating what data? no idea what "vbmeta" is, also no idea about what is "DM verification Disabler"

    Sorry, I'm oversaturated with info because i search for a solution for like 10 hours+ in various websites and youtube, probably i miss something simple.
    If you didn't do something unofficial to unlock the bootloader, then you can boot to TWRP, and then flash this file to can boot to system https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-6.0.zip

    Hello guys..:)
    I would like you to go through XDA new users guide and you must read the FORUM RULES before posting here or anywhere else on xda.

    The rate at which the new users are joining xda on daily basis is very high. A lot of users join because they have got some problems with their devices like bricked phone, bootloops etc. because of following incorrect processes. Some join to help out others, to share their knowledge and gain more.

    So basically this thread is for all of those who want to ask questions and answer those.


    So those who want to help here, just try to answer without flaming, let it be answered thousands of times earlier, show them the path, direction and let them do things on their own. Do not spoon feed, rather just try to point them to right direction.

    This whole idea is of @undercover and the former OP Bruce Wayne and I thank him.

    To The people asking questions here, don't forget to check for the links from 2nd post. That will help you increase your knowledge, and do answer the questions asked by others if you know the answer. Please don't simply say thanks if some member helps you, instead use the thanks button, that will help us keep this thread less cluttered.
