If you tried to use Realme's "deep testing" apk from here and got that nasty "This phone model does not support deep testing." screen, this script may help you bypass it.
Run it like this, replacing the HHH... with the serial number and the DDD...
with IMEI 1 (you can get them both from Settings/About Device/Status):
perl deeptesting-junk.pl pcb 0xHHHHHHHH imei DDDDDDDDDDDDDDD cmd applyLkUnlock
Keep the 0x at the start of the serial number, it's not a typo!
Also notice that --despite the pcb name-- it really is the serial number, not the
pcb number from the engineermode app! 1
Do NOT edit the script to change the model or otaVersion to the ones from your phone; that will defeat the very purpose of this script: namely, to submit the unlock request using your serial + imei and a supported phone model.
If the answer is {"resultCode":0,"msg":"SUCCESS"}, continue with
perl deeptesting-junk.pl pcb 0xHHHHHHHH imei DDDDDDDDDDDDDDD cmd checkApproveResult
If the answer is somethink like
{"resultCode":0,"msg":"SUCCESS","data":{"unlockCode":"0345af...lots of hexdigits"}}
(without any warnings) then try running again the deeptesting app on the phone.
That should now work as described in their tutorials, and the app will reboot the phone
into fastboot/bootloader mode from where you could unlock the bootloader from
your PC with fastboot flashing unlock.
Before running the app, you could also try the script with the actual model and firmware version sent by the app, e.g.:
perl deeptesting-junk.pl pcb 0xHHHHHHHH imei DDDDDDDDDDDDDDD cmd checkApproveResult \
model RMX3474EEA otaVersion RMX3474_XX.L.XX_XXXX_YYYYMMDDHHMM
This worked for me, at some point in February 2023, on a Realme 9 5G RMX3474, the Android 12 GDPR variant of the firmware.
If instead of that all you get is:
{"resultCode":-1006,"msg":"已成功提交审核，正在审核..."}
(even when retrying the checkApproveResult after a couple of minutes), that means
that either their server doesn't work, or they don't accept your serial number or IMEI.
In that case (or if the deeptesting app doesn't work, despite a succesful answer) please open an issue, including the output of:
adb shell pm has-feature oppo.version.exp
adb shell getprop ro.product.name
adb shell getprop ro.product.model
adb shell getprop ro.build.version.ota
I cannot guarantee that that will help, but there still are some leads which could be investigated.
The deeptesting-junk.pl script does nothing else than simulate the https requests
performed by the deeptesting app to their lkf.realmemobile.com server; it does not
save or send any data anywhere else.
On a debian-like linux system, use apt-get install libwww-perl libcrypt-rijndael-perl
to install the modules required by this script.
On windows, the Strawberry Perl distribution includes
those modules by default; to prevent the windows console from mangling the output, set
its code page to utf-8 with chcp 65001 before running the script.
Footnotes
-
The app is getting that value from the
/proc/oplusVersion/serialIDfile. The serial number should be an 8-digit hex number; if the serial number has a different format, then this script will probably NOT work, and you will get the -1006 "please wait till the hell freezes over" result code. ↩
