Flash stock firmware on Lenovo YT3-X50L - General Questions and Answers

Dear Community,
The day before yesterday's evening, my Lenovo YT3-X50L Tablet suddenly shut off. When I tried to boot, It showed me the login screen, I logged in, but one second after showing the Home Screen it crashed and rebooted. I logged in again - it crashed and rebooted again. I couldn't get into my device anymore.
I tried to use the recovery and made a factory reset, after which it showed me the usual Google setup menu (language, wifi, etc.). But it always got stuck at getting a wifi connection, although status was already "connected" and the wifi was working.
I erased the system partition (I don't know if this was a good idea...) and now i cannot boot into anywhere, I only see the Lenovo logo when starting.
I installed ADB, Fastboot and Lenovo downloader on a Laptop. After some hard work, I managed to get an ADB connection and could backup my data.
So now, I just want to put my device back into the state it was when it was shipped!
What I want to mention first: It seems that my sd card was corrupted, I don't know if this was the reason or has anything to do with my sudden device failure. I noticed this because of a mount error in recovery. I formatted the sdcard to FAT with the laptop and the mount error is gone now. The sd card was set as internal storage in Android. If this is possible, I would prefer to use any tool like fastboot to de-assign the sd card as internal storage, and only use the device's own internal 16GB storage, which is more than enough for basic functioning.
I downloaded the device's stock ROM from firmwarefile (just search "Lenovo YT3-X50L stock rom" on google, it's the first result, I am not allowed to post links in this forum as i am a new user) but I don't know how to properly flash it. Flashing the system_xx.img, boot.img, userdata_xx.img and recovery.img files (fastboot flash blabla blabla.img) doesn't make the device boot.
The Lenovo downloader tool isn't working for me. I installed the Qualcomm drivers as described and when I start my device with USB cable connected it shows up in the Tool window, status "flashing", but then gets stuck and doesn't seem to do anything.
Please Help! Might the device itself be dead? I would be very glad if we could resolve the issue very soon because I am on a trip to CERN at the moment and will travel back in a week, and I don't have any other mobile devices with me I could use to show the flight ticket...
My data is already saved, as I mentioned before - I just want my working device back!

Unable to access any memory in INC CM7 nightly 218

HELP!!! yes , its that bad and frustrating for me. THIS IS HTC Incredible .
What happened?
I installed the latest CM7#218, and the phone never was able to restart. It was giving the '3-5 vibrates' symptom. After managing to get into recovery mode, i couldnt see anything from SD card. I later erased and reformatted the sd card but to no use.
In detail:
1. Installed CM7#218.
2. phone restart gives 3-5 vibrate symptom, cant even get into recovery mode.
3. tried factory reset , sd card reformat,repair from windows but doesnt help.
4. only when i unplug the device, power on or when i click on recovery mode, and while on the HTC splash screen, if I connect charger, ONLY then i can get into recovery mode or start the base CM7 OS.
5. in recovery mode i cannot see card , tried all possible mounts/unmounts. thus unable to restore any backups
6 when the base OS boots, (using point#4 above), i still cannot see sd card, nor able to format from phone. in file manager i can see my internal storage. But the phone does not give me any usb mount option , so cannot even view the internal memory from windows.
7. referred to the following thread and many other options etc, but doesnt work.
http://forum.cyanogenmod.com/topic/6...ernal-storage/
the adb shell does not detect my device, tried using 'PDANET' ' ends with 'cannot handshake with device'. tried installing droidexplorer, cannot see my device in the refresh list.
8. Thus as it stands now, i cannot use my internal as well external memory, the web downloads wont go, saying cannot see any memory, same for camera, it cannot see any memory available to it.
9. have already tried N number of restarts, connect disconnect and battery pulls.
10. tried even running the unrevoked, but it cannot connect to device.
11. tried installing all possible drivers as well.
12. its surely not bricked cuz i can use the base OS, and get into recovery through #4 tactics.
HELP!!

[Q] My phone suddenly says "Damaged USB storage"

So, here's the problem - I was just using my phone normally, when it froze - no big deal, recently it has been getting slower and I was just planning on factory resetting it after I back up everything. But, when it booted and went on the start screen, it says "Scanning USB storage for problems" or something like that and it says then "Damaged USB Storage -You may have to reformat it" and unmounts my SD card, so, I have no storage altogether. When I click on the notification it asks if I want to format USB storage. I just want to know if there's a way of retrieving some files, because in my phone FIle Manager there's nothing, and when I connect it to the PC (Windows XP), it doesn't dettect any stotage, if I do it through "USB Utilities" on my phone it shows two Removable Disks on my computer, which are empty, when I click on them it just says "insert disk into drive", and if I click "Turn on USB Storage" on my phone it just keeps on trying to connect, but can't.
I tried restarting it, taking the battery out, booting without an SD card, booting into safe mode, using adb to pull some files, searched the internet for a few hours but to no avail, found this "Tenoshare Android Data Recovery" but it needs root, which I'm not, so I tried rooting it with SuperOneClick - doesn't work, tried installing super user from the recovery menu from SD card, but it can't install it - I'm wondering if it's wortht it. So, now I don't know what to do - do I root my phone using the methods here (with odin and etc) and use that utility, do I just factory reset it (maybe try recovering files after I've reset it?), or is there any other available option to somehow recover the files? I'm on Android 4.0.4 unrooted with Baseband version I9103XXLQ3 - I had installed it a few years ago (my phone came with 2.3.6 and I just followed the instructions here on updating my firmware).
I'll be very grateful with any help, I just had a few more important files and the last time I backed up was in December, so any help is appreciated

[Help Needed] Data (Photos, Videos, Documents) Recovery after soft bricking?

Hello everyone,
I need your help. Sorry for the long post.
I have a OnePlus One. It was running on CM 13.0 (Android 6.0.1). I had TWRP and MultiROM installed.
I have had an issue where whenever I flash a zip file in TWRP, the phone will show an error after installing the zip: "Unable to mount storage". This appeared in red color on the screen right after showing the progress of the zip installation. The phone worked fine and all the flashed zips worked great as well. However, the error that appeared every single time when I flash a zip file bothered me. So I tried to fix it. (I know, if it's not broken don't fix it, but sadly I tired).
I followed this video to get rid of the error => (https://www.youtube.com/watch?v=X7yDPszoQ5s). However, instead of getting rid of the error, I ended up with a huge problem. My phone couldn't recognize the data in the internal storage. It showed that the internal storage was empty. When I tired to reboot in TWRP, It said: "No OS installed are you sure you wish to reboot". I realized that the video I followed was for a different problem and that I ended up with the same issue the video was trying to fix! I tried every single option the video suggested to fix the problem and nothing helped.
I connected my phone to my laptop and downloaded the latest CyanogenMod zip for my phone and I flashed it. when I rebooted my phone I got a screen that asked for my password. I typed a random password (I discovered later that the phone will accept any password and say it's correct). I got the following error: "Decryption Unsuccessful... The password you entered is correct, but unfortunately your data is corrupt... To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your google account...Then the only thing I can select is "reset phone." ". I pressed the reset button on the screen, the phone rebooted and showed the same error. Then I tired flashing PAC ROM and I got the same error again. Then I flashed OmniROM and the phone worked! It didn't show the error.
I have a Titanium backup for all my apps and I also have a nandroid backup for my previous ROM (in my memory stick using an OTG cable). However, I don't have any backups for my internal storage (photos, videos, documents... etc). I am guessing that these files are still in my internal storage. I didn't copy any new files to my phone because I think if I do, then the phone will keep replacing my old files (that I can't see) with the new ones.
My question is: Is there a way to get back these old photos and videos from the internal storage? Note that I didn't delete these files, but the phone can't read them. Also, I checked the nandroid backup that I have and the file system type of the previous ROM was EXT4. My current file system type is the same, EXT4.
Thank you for the help!

No touch screen in TWRP

Hi everyone, I was trying to return my moto g7+ to stock. I had wiped all partitions except internal, ext sd, and otg. I already had motorola_moto_g7_plus_xt1965-2_lake_retail_br_9.0_ppw29.98-66.zip on my sd card, but when I tried to install it it gave me an error message. I then downloaded it from motostockrom.com to my desktop. Then I copied it to a usb thumb drive and connected it to my phone via an otg cable. When I looked for it in TWRP, it wasn't listed. I removed the thumb drive and deleted everything but the .zip file and it still listed all of the files that I had deleted and not the .zip. I rebooted the phone and when it rebooted, I went into TWRP but my touch screen didn't work so I couldn't do anything. I tried to connect to phone via ADB but it wasn't being recognized. Strange thing, when TWRP starts, I can access the internal storage and the micro SD card folders on my computer. I've read other's posts with the same problems but I haven't seen any solutions. I'm using TWRP 3.5.2 _9-0. Any help would be greatly appreciated.
Can you enter fone gui? You need to revoke adb keys in dev options in fone in order to regrant them, then reboot back into twrp, and twrp adb should work, but if you can get in fone gui, and load adb, use Vysor, google it, Vysor gives your pc mouse control of your fone in your pc as if you were at the phone screen. Google Vysor.
An awfy long way to say screen dont work lol, Prob solved in 1 word.
If you cant enter gui, get back to me

I came across a post that mentioned using a mouse with the otg cable so I tried that. I was able to access the controls in TWRP. I was still getting the error message "invalid zip file format! Error installing zip file '/external_sd/Motorola_Moto_G7_Plus_XT1965-2_LAKE_RETAIL_BR_9.0_PPW29.98-111_(by_motostockrom.com) (1).zip".
Is there a spelling error, re: (by_motostockrom.com)? I tried to restore to a point that I had saved from 2020 which said that it had completed sucessfully but resulted in a boot loop. I tried to restore to the other save from 2021, but it gave an error "Cannot restore firmware -- mounted read only." In recovery, if I go to file manager, all of the entries are 20+ character alphanumeric, which I had experienced before when I tried to do a restore but my phone was encrypted.
