Remove Mi Account Xiaomi Chipset Qualcomm [Guide]

Mi account service provided by Xiaomi Inc. China. If you want to use Xiaomi services like syncing data with Mi Cloud, your phone finder service, phone lock, their flash sales offers, Mi F codes, Mi games, Mi themes etc.

Then you must have a Mi account. Normally you can understand that in a normal android you must need a Gmail account same procedure in Mi mobiles you should have a Mi account in order to use their services.

So, this time we will discuss the problem how to remove Mi account Xiaomi machine Qualcomm chipset.

To delete the account of the Xiaomi Mi Qualcomm chipset, we use the following ways:
- Port / extract file "persist.img" in the computer Xiaomi machine
- Use the hex file editing software (for example hex editor: to find the value (hex) of the "ownUserID" file "persist.img", replace the value of this field with the value "00" to accomplish this Mi deleting accounts would require the user to know the use of the tool said the last emmcdl.exe the basic command of this tool: emmcdl_tool_firehouse_files.rar

Emmcdl.exe basic tool command:

Version 2.15
Usage: emmcdl
-l List available mass storage devices
-info List HW information about device attached to COM (eg -p COM8 -info)
-MaxPayloadSizeToTargetInBytes The max bytes in firehose mode (DDR or large IMEM use 16384, default=8192)
-SkipWrite Do not write actual data to disk (use this for UFS provisioning)
-SkipStorageInit Do not initialize storage device (use this for UFS provisioning)
-MemoryName  Memory type default to emmc if none is specified
-SetActivePartition  Set the specified partition active for booting
-disk_sector_size  Dump from start sector to end sector to file
-d   Dump from start sector to end sector to file
-d  Dump entire partition based on partition name
-e   Erase disk from start sector for number of sectors
-e  Erase the entire partition specified
-s  Number of sectors in disk image
-p  Port or disk to program to (eg COM8, for PhysicalDrive1 use 1)
-o  Output filename
-x <*.xml> Program XML file to output type -o (output) -p (port or disk)
-f  Flash programmer to load to IMEM eg MPRG8960.hex
-i  Single image to load at offset 0 eg 8960_msimage.mbn
-t Run performance tests
-b   Write  to GPT 
-g GPP1 GPP2 GPP3 GPP4 Create GPP partitions with sizes in MB
-gq Do not prompt when creating GPP (quiet)
-r Reset device
-ffu <*.ffu> Download FFU image to device in emergency download need -o and -p
-splitffu <*.ffu> -o  Split FFU into binary chunks and create rawprogram0.xml to output location
-protocol  Can be FIREHOSE, STREAMING default is FIREHOSE
-chipset  Can be 8960 or 8974 familes
-gpt Dump the GPT from the connected device
-raw Send and receive RAW data to serial port 0x75 0x25 0x10
-verbose Enable verbose output
Examples: emmcdl -p COM8 -info
emmcdl -p COM8 -gpt
emmcdl -p COM8 -SkipWrite -SkipStorageInit -MemoryName ufs -f prog_emmc_firehose_8994_lite.mbn -x memory_configure.xml
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -x rawprogram0.xml -SetActivePartition 0
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -ffu wp8.ffu
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -d 0 1000 -o dump_1_1000.bin
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -d SVRawDump -o svrawdump.bin
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -b SBL1 c:\temp\sbl1.mbn
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -e 0 100
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -e MODEM_FSG
emmcdl -p COM8 -f prog_emmc_firehose_8994_lite.mbn -raw 0x75 0x25 0x10

The steps are as follows:

1. Switch the phone to the mode EDL:

2. Next run emmcdl:

emmcdl.exe -l

- After you have found the port, you run the following command to port/dump file "persist.img" on computer

emmcdl -p COM * -f prog_emmc * .mbn -d persist -o persist.imb

  • For example, if the com port is 10, replace COM* -> COM 10
  • Prog_emmc*.mbn -> this is the firehose file comes with corresponding tool emmcl.exe Qualcomm chipset your machine Xiaomi, example your machine use Qualcomm 8953 chipset, the selected file is firehose "prog_emmc_firehose_8953_oppo_r9s.mbn"
--> The complete follow examples:

emmcdl -p COM 10 -f prog_emmc_firehose_8953_oppo_r9s.mbn -d persist -o persist.img

3. Run the software hex editor, load the file "persist.img", find the "ownUser" find the hax value of this field (in this case, the value of this field is: "161659...")-> instead of the hex value this with the value of 00: 31 36 31 36 35 39 31 30 37 38 --> 00 00 00 00 00 00 00 00 00 00 -> then saved

4. The next step is a reverse port file "persist.img" Xiaomi on the computer, type the following command

emmcdl -p COM * -f prog_emmc * .mbn -b persist persist.img

Note: remember to replace the value of the two fields in order: COM * , prog_emmc*.mbn

5. Turn off the power and restart the computer, this time is no longer sticky machine Mi another account
(in case the machine is operating in the "Lost Mode", after booting up the account still see the machine stick Mi but do not worry, just press trigger button (activate), after the machine has to be account logout mi) ..................
