What is Xiaomi Repair Tool (XRT)?

Xiaomi Repair Tool (XRT) is a Xiaomi device repair solution providing Mi Account lock removal, FRP bypass, IMEI repair, and firmware flash operations for Xiaomi, Redmi, and POCO devices.

Supported Operations

OperationDescription
Mi Account BypassRemove Mi Account lock from recovered, second-hand, or forgotten-password devices. Supports MIUI 11 through HyperOS via BROM/EDL methods
FRP RemoveGoogle Factory Reset Protection bypass through multiple chipset-appropriate methods
IMEI RepairFix null/invalid IMEI (baseband unknown) via NVRAM write (MTK) or NV items (QC)
Flash FirmwareFull and partial firmware flash with ARB (Anti-Rollback) awareness. Dead-boot recovery via EDL/BROM
Factory ResetDeep factory reset with FRP + Mi Account partition clean
Read Device InfoIMEI, serial number, hardware info, bootloader status, ARB index

When to Use XRT

  • Customer brings a Xiaomi/Redmi/POCO locked to a forgotten Mi Account
  • Device shows "This device is locked" after factory reset
  • Phone stuck in boot loop or dead boot (qualifies for EDL/BROM flash)
  • IMEI shows as "null" or "invalid" (baseband unknown after failed flash)
  • Carrier-locked Xiaomi needing unlock for different region SIM

How to Use Xiaomi Repair Tool (XRT): Step-by-Step

  1. Purchase XRT credits from Code-GSM
  2. Download, install, and log in
  3. Connect Xiaomi/Redmi/POCO device via USB in Fastboot, BROM, or EDL mode
  4. Read device info to confirm detection
  5. Select operation: Mi Account Bypass, FRP Remove, IMEI Repair, Flash, Factory Reset
  6. Execute

When to Use Each Connection Mode

  • Fastboot (Vol Down + Power): Best for bootloader unlock, flash, basic Mi Account removal. Requires some battery charge
  • BROM (Vol Up + USB, MTK only): Best for MTK devices with locked bootloader. Can access NVRAM directly
  • EDL/9008 (test point or command): Emergency mode for dead/bricked devices. Works with zero battery

Xiaomi / Redmi / POCO Connection Modes

ModeHow to EnterChipsetUsed For
Fastboot ModePower off → hold Vol Down + Power together until Fastboot/Mi Bunny screen appears. Shows "FASTBOOT" or the Mi Bunny dead animation. Connect USBAll (MTK + QC)Flash ROM, bootloader unlock, FRP erase (unlocked BL), Mi Account removal (some methods), reboot to other modes
MTK BROM ModePower off completely → hold Vol Up → plug in USB. If Vol Up doesn't work, try Vol Down. Phone shows as "MediaTek USB Port" (COM) in Device Manager. No screen display in BROM modeMediaTek onlyNVRAM read/write (IMEI repair), format userdata+frp, Mi Account partition erase, flash scatter file, DA auth bypass for locked BROM
Qualcomm EDL (9008)Options: (1) adb reboot edl from ADB; (2) fastboot oem edl from Fastboot; (3) Hardware test point (short two test pads on PCB while connecting USB).

Anti-Rollback (ARB) Protection — Critical for Xiaomi

Xiaomi devices implement an Anti-Rollback (ARB) counter burned into the chipset's eFuse storage. Each firmware version has an ARB index. Flashing firmware with a lower ARB index than the current burned index will permanently brick the device — this cannot be repaired by any tool.

  • Always verify that the target firmware's ARB index is equal to or higher than the current device ARB before flashing
  • Xiaomi Flasher Pro and most modern Xiaomi tools check ARB automatically and warn before proceeding
  • A device bricked by ARB violation cannot be recovered — it is a hardware-level permanent lock

Troubleshooting Xiaomi / Redmi / POCO Operations

ProblemLikely CauseSolution
Mi Account lock persists after bypassMi Account partition was not fully erased, or MIUI/HyperOS re-applies the lock from a backup on first boot(1) Do not connect to WiFi after the operation until you have fully set up the device; (2) Perform a full factory reset including userdata AND the mi_account partition; (3) For HyperOS: some methods require EDL firehose with a specific programmer that supports the HyperOS partition layout. Update the tool to latest version
MTK Xiaomi not detected in BROM modeMTK VCOM driver not installed, phone has DA authentication (newer MTK SoCs), or Vol key held too lateInstall MTK VCOM drivers. For newer MTK SoCs (MT6833/MT6853/MT6877+) with DA auth: the tool requires a bypass DA file. Check if the tool version supports your specific SoC. Hold Vol key BEFORE connecting USB, not after
Qualcomm Xiaomi not entering EDL (9008)Fastboot restrictions, ADB not authorized, or EDL command blocked by security(1) Try adb reboot edl first; (2) Try fastboot oem edl; (3) Use hardware test point — short specific pads on the PCB while connecting USB. Test point locations are model-specific (search "[model] edl test point"). Phone in EDL shows "QHSUSB_DLOAD" in Device Manager
Flash fails with "ARB Update" or "Anti-Rollback" warningTarget firmware has lower ARB index than deviceSTOP — do NOT proceed. Flashing will permanently brick the device. Find firmware with an equal or higher ARB index. Use the current or newer firmware only
Bootloader unlock fails / "BL unlock not allowed"Unofficial unlock: needs Mi account with 72-hour unlock waiting period. System app hasn't marked device eligibleLog into Mi account, apply for unlock at unlock.update.miui.com, wait 72h or 168h (7 days for newer models). Use MiFlash Unlock official tool. Some HyperOS devices require additional waiting
Phone boots to MIUI/HyperOS logo loop after flashFastboot ROM flashed on locked bootloader, missing partitions, or incomplete flashUse EDL or BROM mode to flash the FULL ROM (not just Fastboot-only partitions). Ensure all partitions (boot, system, vendor, userdata) were included. For BROM: use scatter file with all partitions selected
IMEI shows baseband unknown / null after NVRAM repairNVRAM write incomplete — both IMEI1 and IMEI2 must be written, not just IMEI1Retry: write IMEI1 AND IMEI2 in BROM mode (MTK) or NV items 550 AND 551 in Diag mode (QC). Flash the modem/baseband partition if IMEI still shows null after write attempt
FRP removed but setup wizard still shows Google account screenUserdata FRP flag was cleared but the dedicated frp partition was not erasedErase the frp partition specifically (not just factory reset). In Fastboot: fastboot erase frp. In BROM: select format frp partition. Disconnect WiFi before testing the result

Frequently Asked Questions — Xiaomi / Redmi / POCO

Q: What is the difference between Mi Account removal and FRP bypass?
A: Mi Account is Xiaomi's own cloud-based device lock — it activates after factory reset and requires the original Xiaomi/Mi credentials. Google FRP is Android's Google account lock — also activates after factory reset but requires a Google account. Xiaomi devices can have BOTH locks simultaneously. Both must be removed separately.

Q: My Xiaomi is MTK or Qualcomm — how do I find out?
A: Settings → About Phone → Processor (or CPU). MediaTek shows "Helio" or "Dimensity." Qualcomm shows "Snapdragon." Generally: Redmi Note (base), Redmi A/C series, POCO M/C = MTK. Xiaomi Mi/POCO F/X series, Redmi Note Pro/K series = Qualcomm. The chipset determines which mode (BROM vs EDL) and which IMEI method to use.

Q: Will bootloader unlock remove all my data?
A: Yes — official Xiaomi bootloader unlock via Mi Unlock Tool performs a full data wipe. This is by design. Back up all data before proceeding. Third-party BROM/EDL bypass methods may or may not wipe data depending on the method.

Q: What is MIUI vs HyperOS? Does it change repair procedures?
A: MIUI is Xiaomi's older Android skin (up to MIUI 14). HyperOS is the replacement introduced in late 2023 for Xiaomi 14 series and newer flagships. HyperOS changed some partition layouts and added stricter security. Some older bypass methods no longer work on HyperOS — always verify tool support for HyperOS before ordering.

Q: Can a device bricked by Anti-Rollback be recovered?
A: No — ARB violation burns a permanent eFuse flag. The device will not boot and cannot be recovered by any software or hardware method. This is why respecting ARB warnings before flashing is critical.

Q: After Mi Account removal, the phone asks for Mi Account again on first boot — why?
A: This usually happens if the phone connected to WiFi during or after the bypass and downloaded account data again. Do not connect to WiFi immediately after Mi Account removal. Set up the device offline first, then connect to WiFi after completing the full initial setup.

Q: How do I check credits and order history?
A: Log in to code-gsm.com. Your credit balance and order history are visible in your account dashboard.
