I have a galaxy tab 3 that I used back in 2015 but then it died but then in 2021 I revived it by disconnecting and reconnecting the battery and it booted again and I used it for a few years to play old android games but then after turning it on again after the battery drained it turned on but I realized I couldn't get any files on to the tablet, downloads would fail and I couldnt share files with Bluetooth and then i tried creating a new Minecraft world and it created but once I exited it disappeared and when I tried creating a folder manually using my files it showed access denied and I can delete files and they stay deleted so it isnt an eMMC issue so anyone know how to fix it? I read online it is an issue with the Android media framework or SELinux so does anyone know how to fix it without wiping the tablet? I also installed twrp btw just incase I need to use it

I have an old htc wildfire that works but recently the battery has started swelling but I cant find a cheap replacement since all of the batteries are really expensive, don't ship where i live (I live in the UAE) or are cheap but have really expensive international shipping so anyone know where to find cheap htc wildfire batteries? I also don't want official ones since those are probably going to swell in a few years since those batteries are ancient

So my uncle bought an ipad but it is locked to a school called Fort Bend so anyone know how to remove or circumvent the MDM lock. It is on ios 26 I believe and I cant use mdmpatcher because I don't have a mac

I have a galaxy tab 3 7inch running android 4.4.2 and is running into a strange issue where nothing is saving (photos, mc worlds etc..) and trying to create a folder manually through the My Files app shows the error Access Denied. Anyone know how to fix this? I know it probably isnt a NAND fault since I can still delete files and enable developer mode (which changes a flag) so i can delete data and modify existing data but I cant create new data unlike if the NAND became read only then I couldnt delete or modify data

I have an old galaxy tab 3 7.0 that I used to use back in 2015 and I found it and booted it up again but I ran into a strange issue where it wouldn't connect to wifi (the toggle would just turn itself off and it isnt a chip problem since bluetooth works fine) and when I try transferring a file over bluetooth it didn't work and trying to install and apk through adb shows a no space left on device error even though there is clearly 4gb left as it says in settings and also I cant save any photos or any mc worlds but I can delete files so anyone know how to fix this?

I have a galaxy tab 3 7.0 that has completely broken wifi and Bluetooth, wifi and Bluetooth don't even turn on unless I let the tablet sit for a couple months and then turn it on and even then it only works for a day or two before breaking again and when it is on it fails to download files even though there is a gig free. anyone know how to fix this since it is my childhood tablet and I want to see it working again fully

I have a galaxy tab 3 7.0 that has completely broken wifi , wifi doesnt even turn on unless I let the tablet sit for a couple months and then turn it on and even then it only works for a day or two before breaking again and when it is on it fails to download files even though there is a gig free. I dont think the chip is the issue since Bluetooth works fine and I can even Bluetooth tether with my galaxy tab s10 fe. anyone know how to fix this since it is my childhood tablet and I want to see it working again fully

Things I have tried: Wiping cache, rebooting multiple times

I have an iphone 11 on ios 16.5.1 with dopamine and I was trying to install jade and it did install but all my cc modules were gone except the 4 stock ones and adding or removing any didnt work and I narrowed down the problem to ccsupport. Anyone know how to fix this? I cant use an alternative since jade needs ccsupport ae a dependency

I am trying to run a debian chroot on my Dlink DSL-2750U C1 but debian needs an FPU/FPU emulation but my router doesnt have an FPU and the stock images dont have any FPU emulation support but I read online that you can compile openWRT with FPU emulation support but when I try to compile from source I cant find any options for FPU emulation so does anyone know how to do it?

I have a ps4 slim that I got in 2022 but was used from 2018, but i just started having this weird issue after i used the ps4 temperature utility where when I launch something even remotely intensive (e.g EZFN fortnite) the ps4 gets immediatly to my temperature limit and also smells like something cooking. I cleaned out the fans and I still have the same issue so does anyone know what this is?

I have a dell inspiron 6400 that doesnt get power unless I leave it for a couple minutes after shutting down and I saw online that this means a capacitor / PMIC faliure so is it fixable without total motherboard replacement? I am also not interested in micro-soldering because for that price I could probably get a new dell laptop

I have a dell inspiron 6400 that has a dead fan and I want to replace it but all the fans either dont ship internationally or are very expensive especially for this old of a laptop. I need ones under 40 AED (10 dollars) and ship internationally so anyone know where to find them?
