TL;DR: Fix Redmi 7A bootloops by isolating side buttons, checking battery, or reflashing. PLN 115 service quoted; “unlock and additionally upload a new system.” [Elektroda, adamskippl70, post #20130337]
Why it matters: For Redmi 7A owners stuck in a reboot loop, this gives quick fixes and real-world costs so you can decide next steps.
Quick Facts
- Side‑key ribbon isolation is a first diagnostic step; lift the head plate so it doesn’t touch the tape. [Elektroda, blahfff, post #20071303]
- Bootloop may point to software boot issues or board corrosion/damage. [Elektroda, winmap, post #20071727]
- A battery can be bad even if not swollen; confirm before chasing board faults. [Elektroda, KRY5PIN, post #20072546]
- Reported costs: PLN 115 at Xiaomi service; ~PLN 100 at local shop for unlock + ROM. [Elektroda, adamskippl70, post #20130337]
- Mi Account lock removal requires Xiaomi verification; “Only they can help.” [Elektroda, winmap, post #20130089]
Why does my Redmi 7A keep rebooting in a loop?
Common roots include corrupted system software, a weak battery, or a faulty mainboard. As one repair helper notes, “try reloading the soft.” If flashing does not change behavior, suspect the motherboard. Start with power and software before deeper hardware work. [Elektroda, winmap, post #20076585]
How do I test if the side buttons or flex are causing the bootloop?
Isolate the side‑key ribbon to rule out stuck keys causing resets.
- Power off and open the back carefully.
- Lift the head plate so it does not contact the side‑key tape.
- Power on and observe if the loop stops.
This isolates a shorted or stuck side key flex. [Elektroda, blahfff, post #20071303]
Can a non‑swollen battery still cause bootloops?
Yes. A battery can be faulty even if it looks normal. Do not assume health based on swelling alone. Test with a known‑good battery or substitute power. Rule this out before deeper repairs. [Elektroda, KRY5PIN, post #20072546]
What is a bootloop on Redmi 7A, and does it mean board damage?
Bootloop means the phone restarts repeatedly without reaching the system. On 7A, it can indicate board corruption. Software issues can also trigger it. If symptoms persist, hardware diagnosis may be required. [Elektroda, winmap, post #20071727]
Do I need Developer options or USB debugging to use MiFlash?
You can attempt flashing via Fastboot without entering Android settings. In the thread, MiFlash was used despite no access to settings. Boot to Fastboot, select a fastboot ROM in MiFlash, and flash. This approach avoids USB‑debugging toggles. [Elektroda, adamskippl70, post #20080154]
MiFlash says 'cannot find flash_all_except_storage.bat'—what should I do?
That message means MiFlash cannot find the specified script in your ROM folder. The author saw this after unzipping several ROMs. Verify the unpacked ROM contains that .bat file before flashing again. Try another fastboot ROM archive if needed. [Elektroda, adamskippl70, post #20080154]
I can’t enable USB debugging because the phone bootloops. How can I proceed?
Tools that need USB debugging will not work in a bootloop. The author tried Mi Unlock and MiTool, which requested USB enablement. Use Fastboot‑based flashing, or contact support for unlock services. This avoids the need to enter Android settings. [Elektroda, adamskippl70, post #20077271]
After flashing, the phone asks for a Xiaomi account. What does that mean?
The device is locked to a Mi Account. Support must verify ownership and remove the lock. As one helper says, “Only they can help.” Avoid unofficial bypasses, as they can end badly. [Elektroda, winmap, post #20130089]
What information did Xiaomi Support request to remove the lock?
They asked for the phone’s IMEI and the SIM card number. Provide accurate identifiers so they can verify ownership and assist. Then wait for their response. [Elektroda, adamskippl70, post #20129786]
How much will unlocking or service cost, realistically?
Reported quotes were PLN 115 from Xiaomi service. Local shops quoted about PLN 100 for unlock plus ROM install. Compare cost with the phone’s value before proceeding. These prices can guide your decision. [Elektroda, adamskippl70, post #20130337]
What if disconnecting the side keys and battery didn’t change anything?
That can happen. One user disconnected the battery and lifted the board, and the loop persisted. Continue with software flashing or formal board diagnosis. [Elektroda, adamskippl70, post #20076430]
Can the SIM card trigger a bootloop?
It is cited as a possible cause. Remove the SIM and test boot behavior. If the loop stops, replace the SIM or clean contacts. If not, continue diagnostics. [Elektroda, adamskippl70, post #20071280]
