[Q] how do i get my phone back in it's original state?

hi,
recently i have rooted my phone to get the most out of it.
a couple of weeks ago i got this notification message that an update was available for my phone's software, so i downloaded it via OTA.
when it restarted to install the update it came into CMW recovery mode. there is an option in CMW to install the update, but when i trie to install it, i get an error mesage that sais: no such file or directory. so i tried to update it manually and to get out of CMW recovery, but nothing helps. i also tried to get it back in it's original state, but apparently no one with this phone model has ever asked it on the internet, so i can't find a solution.
can anyone on this forum please tell me how i get my phone back in it's original state? if i lose my root acces, that doesn't matter. i just want my phone back.
my phone model is:
LG Optimus L3 (e400)
please help me, i have tried other forums, but no one gave a response there.
greetzz..

[Q] Storex Ezee Tab 74D14-S Tablet

Hey guys I'm new here and I found myself with a situation. Sorry if this isn't the right area to post this.
So my friend has this tablet: Storex Ezee Tab 74D14-S. And it got bricked, stuck on logo screen.He doesn't have warranty. Tried hard reset, power volume +/-, got into recovery mode and wiped cache,factory reset all that stuff. Yet it's still stuck on logo screen. So I went searching for firmware to install the OS. I found this link but I can't post it due to not having permission yet, you can find it by searching "Storex Ezee Tab 74D14-S firmware" first link, first PDF and it has 2 links. So I downloaded the firmware and the program to try it out. However to use this program, called phoenix I need to have USB Debugged on, and I can't do that obviously. Went searching for custom ROM's but I didn't find anything for this tablet. Also I'm no expert on rom's and I don't wanna screw this even more.
So I'm opened up for suggestions guys. Thanks.
EDIT: Is there a way to reinstall firmware from recovery mode? I can seem to get into recovery mode, but it can't be charging or else it doesn't work, although it's a bit buggy can't go up only down and says "No command".

[Completed] [Q] Bootlooped Redmi Note 4G/LTE

Hey guys, I recently got a Redmi Note, and decided to root it, as I've seen many good things come out of rooted phones. I didn't have access to a computer at the time, so I used Kingroot to root the Note. (I can't read Chinese, so I can't really tell what it did.) And success, it was rooted. Soon, an OTA update came and I decided to download and install it. It booted up fine, but apps kept crashing (incl Kingroot) and I couldn't even get to the landing page/homescreen. I searched up the internet to try and load a fresh stock rom into it, cause I wanted to unroot the phone. (and still do) I tried using the Mi PC suite and load the stock rom into it, but it got stuck at sending userdata.img, and now I'm stuck at the Mi.com logo. (There's no powered by android sign at the bottom.) I've tried getting into recovery, but whenever I press vol down + power button, it takes me straight to fastboot.
TL;DR: I was an idiot and downloaded an OTA update onto my Redmi Note that was rooted via Kingroot running a stock rom. Tried to use Mi PC suite to load the stock rom onto it, but got stuck at userdata.img, and got it into a bootloop. Seek to unroot it and start afresh with a stock rom.

i can also get clockwork mode but i just have error closed... i installed all the drivers i was able to found but no one fixed the "error closed" when using sideload, also i don't know WHERE IS THE STOCK ROM...
I have this www needrom com download chuwi-vi8-dual-os
"file is too big" so i format in NTFS but then the tablet won't recognize it, and seems like it's the WINDOWS ROM i don't need the WINDOWS ROM I JUST NEED THE STOCK ANDROID ROM
i've been trying to fix this since MONTHS, tried yesterday, it took my whole day today and yesterday STILL NOTHING.
i reposted this here beacause i think i wasn't in the good category sorry i'm new
IF someone can REALLY HELP ME, do i'll have to PAY SOMEONE to fix my tablet ??? Like really, i already posted this in december no one answered me...

Ok, so it can't be fixed, great ! Thanks ! XDA brokes my device and won't repair it....

Bricked p40 pro after downgrade...

Hello
I have a soft bricked (?) p40 pro , after downgrading to a wrong firmware version, the phone booted up normally inside android and was working for a while.
But after trying to OTA update it, the phone went into a bootloop. Failed at installation and restarted.
I can access now only eRecovery and Fastboot modes.
I can't get it recornized by a PC with usb, i dont know if i do something wrong.
eRecovery also doesn't work. It managed to find once a package, downloaded it and while installing the deviced rebooted and went into bootloop again.
Now its stuck to unable to find package info.
Haven't try dload from usb-tongle, because i dont have any usb tongle / adapter. Im willing to get one to try out, if i can flash anything from there.
I went to a service shop, they said they tried with test point and they still didn't find a work around it. Maybe they lack experience on this device.
If someone can help me please, im very desperate
I had the phone only for 4 hours
Thanks
Alex
