    Hello, I have a problem with the phone, namely it resets continuously without being able to perform any action. It says at the bottom of the screen while you see the power up screen "efuse blow: successes". Maybe someone knows what's going on?

    This message is nothing unusual. The power button should be checked first. It can be short-circuited, making it active all the time and restarting the phone all the time.

    One more thing. At the same time, someone was logging into the Google account from an unknown device, possibly a coincidence. Just wanted to add

    Same suggestion as before. First thing to check is the power button.

    Previously it was working because fastboot was running, but after installing TWRP it stopped.

    It had to start with that. Re-upload all the soft, preferably with a box in bootrom mode, or at least restore the original recovery partition to rule out this problem.

    Okay, but it won't turn on recovery or fast, you won't even turn it off unless you disconnect the battery, so that's a big problem

    It was enough to read. If you don't know what it is, take it to the site.

    This is not a problem or an error. It's just that this model displays such a message at the bottom, that's all. This is normal.

FAQ

TL;DR: 1 boot message—"efuse blow: success"—is normal on Redmi 9; "This is normal." This FAQ explains what it means and what to do if reboots occur. For Redmi 9 owners seeing the message or boot loops. [Elektroda, blahfff, post #21231207]

Why it matters: It helps you separate a harmless boot note from real faults and choose the fastest safe fix.

Quick Facts

What does "efuse blow: success" mean on a Xiaomi Redmi 9?

It is a boot-time note shown by this model. It does not indicate a fault or error. “This is not a problem or an error.” You can keep using the phone if everything else works normally. [Elektroda, blahfff, post #21231207]

Should I worry if the message appears but the phone works fine?

No. The message is normal on Redmi 9 and not an error. If the phone operates normally, you do not need to act. Keep the software and data backed up as routine practice. [Elektroda, blahfff, post #21231207]

Why does my Redmi 9 keep restarting by itself?

A stuck or shorted power button can keep the device in a restart loop. Check that the power key isn’t held down or shorted. “The power button should be checked first.” If the button is faulty, repair or replacement is needed. [Elektroda, blahfff, post #19862369]

How do I check if the power button is causing the reboots?

Try this quick check.
  1. Remove any case and clean around the power key.
  2. Press and release the power key several times, ensuring it clicks and releases.
  3. Watch if the loop stops; if it returns, have the button inspected. “As advised: The power button should be checked first.” [Elektroda, blahfff, post #19862369]

Pressing the power button a few times stopped the restarts. Did that fix it?

It may have temporarily cleared the issue. One user pressed the power button and the phone worked “for now.” If reboots return, the key may still need service. Monitor the device and plan a repair if symptoms recur. [Elektroda, Sylwek123454, post #19862376]

I installed TWRP and now it bootloops. How can I recover?

Re-upload the full firmware. At minimum, restore the original recovery partition to rule out a recovery issue. If possible, flash in BootROM mode using a service box for reliability. This approach addresses recovery-related boot problems. [Elektroda, blahfff, post #20511751]

I can’t enter Fastboot or Recovery—what should I do next?

Flash the phone in BootROM mode with a professional service box. This bypasses normal boot stages and lets you reload software. If you don’t know how, take the phone to a service center. This is the recommended path. [Elektroda, blahfff, post #20512134]

I can’t power it off during the loop. Is battery disconnect the only way?

In a severe loop, the device may ignore power-off requests. One user had to disconnect the battery to stop it. Consider service flashing afterward to restore normal boot. Reconnecting without a software fix can restart the loop. [Elektroda, smaciek500, post #20511768]

Does the message mean my phone’s eFuse is damaged?

No. On this model, the bootloader simply displays that line during startup. It is not evidence of hardware damage. Treat it as informational unless other faults appear. [Elektroda, blahfff, post #21231207]

After installing TWRP, Fastboot stopped working. Is TWRP related?

Yes. One user reported Fastboot stopped immediately after installing TWRP. If your symptoms match, revert to stock recovery or full stock firmware. That isolates recovery as the cause. [Elektroda, smaciek500, post #20511743]

What are BootROM mode and a “box” in this context?

The responder recommended flashing in BootROM mode using a service “box.” This is a professional low-level flashing approach. It is used when normal modes fail. Ask a repair shop if you lack the tool. [Elektroda, blahfff, post #20512134]

I don’t know what BootROM or a box is—should I visit a repair shop?

Yes. The advisor stated: “If you don’t know what it is, take it to the site.” A service center can handle BootROM flashing safely. This avoids further damage. [Elektroda, blahfff, post #20512134]

Will the “efuse blow: success” line disappear after I fix other issues?

No. The line is a normal boot message for this model. It will continue to appear on startup. Focus on actual faults like boot loops, not the message itself. [Elektroda, blahfff, post #21231207]

Is a Google login alert connected to this boot message?

One user saw a Google-account login alert around the same time and suspected coincidence. Treat account alerts separately from phone boot notes. Address security notifications within your Google account. [Elektroda, Sylwek123454, post #19862376]
