[Lenovo Vibe K5 Plus Questions & Answers] bryrrea:
Hello everyone! I hope you're doing well. I'm new here and I'm facing a problem that I can't seem to solve, so I'm here to ask for your help.

CONTEXT: My girlfriend had a phone whose screen broke. She couldn't afford to buy a new one, and neither could I help financially. But I had two old devices: a Motorola G1 (which I used to store some things and do simple tasks) and a Lenovo Vibe K5 Plus, which was the one I was using. Since I had just graduated from college and she hadn't, she had a greater need than me for a slightly better phone. So I gave her my Lenovo and I'm using the Motorola. When the Lenovo was still with me, I had put a custom ROM on it from Lineage (I think it was Android Nougat, if I'm not mistaken) and it also had TWRP. Before giving it to her, I only did a quick format of the phone.

A few days ago, there was a problem with the Lenovo and Android no longer worked. The phone turned on, entered the Lineage boot screen, but when it tried to turn on Android, a message appeared saying that Google's text-to-speech had continuously failed, and the phone turned off. She brought it to me yesterday and I thought about installing the original stock ROM on the device. With difficulty, I managed to get the laptop (Windows 10) to recognize the phone when it turned on. The difficulty was because when I tried to turn it on, the screen kept flashing on the Lenovo. I opened the device, took out the battery, waited for a while, and miraculously managed to turn it on. When it turned on, the laptop installed the device before it turned off. Through ADB, I managed to get the device to reboot directly to recovery, since I couldn't access recovery through the physical buttons on the device.

So, I managed to make a backup of the files that were important to my girlfriend and that were on the phone's internal memory. After that, I formatted the device through TWRP using the "format data" button. Still, I used the wipe to erase everything except for "USB-OTG" and the memory card option (which I had removed along with the SIM card before trying the procedure). After that, I restarted the phone to enter TWRP directly.

PROBLEM: After doing this, I tried to install the stock ROM using ADB sideload, but it said there was something wrong with the image I was using. The sideload gave an error message and said that the phone needed to be restarted. I restarted it from this screen by sliding my finger to the right, and... the phone no longer turned on and wasn't recognized by the laptop! I can't access TWRP through the physical buttons (at least not through the traditional method I know, which is the volume up button and the power button), ADB doesn't recognize the phone, and I don't know what else to try.

QUESTION(S): How can I force the laptop to recognize the device so that I can make it reboot directly to TWRP, since the device doesn't turn on for long enough for Windows to try to check the drivers? Or has TWRP been corrupted? If so, how can I install TWRP again? Is there any other way to access recovery? Is there any other way I can use to install the stock ROM? We can't afford to take it for repair at this time (the situation here in Brazil is very bad), much less afford to buy a new device. Does anyone have any other ideas on how I can access recovery or how I can install a ROM without necessarily turning on the device? Or any other ideas?

I really appreciate anyone who read this far and, in advance, I thank anyone who can help me. Gratitude!
