I purchased this phone for my parent as listed. I know it’s an older device, but I specifically wanted a small-size phone, and considering the price, it seemed like a good deal. At first, everything looked fine. I didn’t notice any issue initially, but after a few days of delivery, I started realizing the phone was quite different. Then, mysteriously, it even got cracked while in my pocket… but it was still functional. Later, I thought of installing a custom ROM because the performance wasn’t as expected—it felt slow at times. It was just for experimentation, but when I updated it to the latest patch, the phone got completely bricked. I was shocked. I contacted the shopping site, and they told me to visit a service center. The service center denied any support. After that, I started investigating myself and found out it was actually a Chinese variant. That made me question how it was even running Global MIUI. I then tried flashing Global MIUI again—didn’t work. So I decided to flash Chinese MIUI, and surprisingly, it worked perfectly. The phone felt much faster too (Chinese ROMs are indeed smoother). But the happiness didn’t last long. The moment I connected to WiFi, I got a warning that the phone is locked and requires a Mi Account login. That’s when I realized—it was likely a stolen phone from China, modified and sold elsewhere. I tried raising issues, but nothing worked. After a lot of research and effort, I managed to bypass the restriction using modified flash files and got it running again on Global MIUI. It works now, but I actually want to go back to Chinese MIUI properly. From what I’ve found, the only reliable way seems to be using a tool called **UnlockTool** , which is paid. I tried alternatives, but nothing worked. Most people seem to rely on that tool because of its reputation. So my question is simple: **Does anyone have access to UnlockTool or know any way (even cracked or alternative) to use it for this purpose?** It’s not mandatory since the phone is working, but I’m a curious person—I like diving into these things and fixing them fully. Would appreciate any help. ---

_Redmi 7A (Chinese variant) stuck on Mi Account lock after flashing → paid tools like UnlockTool not needed → free fix below._ Your Redmi 7A has an SDM439 chip — it lets you flash via EDL **without any paid auth** using the free [**Mi Flash Tool**](https://xiaomiflash.com/) + tweezers on the test point. Grab the free [**ENG ROM (keepNV)**](https://androidfilehost.com/?fid=17248734326145716362) (~619 MB), flash it through EDL → it permanently kills Mi Account, FRP, and WiFi relock. Then flash [**Chinese MIUI**](https://miuirom.org/phones/redmi-7a) on top — same anti-rollback index, won’t brick. 🔓 > 💡 **Shortcut before opening the phone:** tap the lock icon 10x → note the 12-digit code → [check CLEAN/LOST status](https://imei-server.ru) ($2–5). If CLEAN, a [$15 server unlock](https://www.martview.com/remove-xiaomi-micloud-account-via-remotely-all-model-supported-processing-time-hours-imei-service.html) fixes everything permanently without touching hardware. > ⚠ **“keepNV” in the filename is non-negotiable** — without it the flash wipes your IMEI → Unknown Baseband → no calls, no data. If your download doesn’t say keepNV, get it from [Halabtech](https://support.halabtech.com/index.php?a=downloads&b=folder&id=121953) or [GiveMeROM](https://www.givemerom.com/index.php?a=downloads&b=folder&id=11387) instead. > **🔓 Full walkthrough — every path, every step, every trap** > > * * * > > ### 🎯 Step 0 — Check CLEAN vs LOST (do this first) > > Xiaomi’s server keeps a blacklist by **serial number** (not IMEI). That’s why partition wipes don’t stick — phone connects to WiFi, server says “still locked,” phone relocks. > > Two categories: > > - **CLEAN** = owner forgot password or second-hand sale. Server unlock works. > - **LOST** = reported stolen via [i.mi.com](http://i.mi.com) (shows a message on screen). Server services reject these. > > Your phone (Chinese hardware modified for resale) is probably LOST. But check anyway — it takes 2 minutes: > > 1. Lock screen → tap the lock icon **10 times** → 12-digit unlock code appears > 2. Note your IMEI (`*#06#` or check the box) > 3.

Can’t reset, can’t update, can’t reflash. Band-aid that blocks your actual goal (Chinese MIUI). > - **bkerler edl.py** — auth module hangs on SDM439 ([GitHub #576](https://github.com/bkerler/edl/issues/576)). Use Mi Flash Tool instead. > - **“UnlockTool crack” downloads** — all malware. It’s hardware-dongle-based, no crack exists. > - **MiTool (Termux)** — wraps Xiaomi’s official API. Chinese variant + non-Chinese account = region mismatch = rejected. > - **Dr.Fone / 4uKey / DroidKit** — cost more than the phone.
