Thank you very much for the guide.
I tried it with
XT1922-5_ALJETER_RETLA_8.0.0_OPP27.91-143_cid50_subsidy-DEFAULT_regulatory-XT1922-5_CFC.xml
Didn´t work. Booting got stuck with the "Bad Key" black screen.
Going through the output of the batch file, this is what I found a couple of error messages:
fastboot flash dsp dspso.bin
fastboot: error: cannot load 'dspso.bin': No such file or directory
fastboot flash boot boot.img
Sending 'boot' (16384 KB) OKAY [ 0.520s]
Writing 'boot' (bootloader) Image signed with key bad key
OKAY [ 0.693s]
Finished. Total time: 1.220s
Regarding the first issue, there is a file called "adspso.bin" as part of the stock rom (instead of dspso.bin).
Can somebody help me with to modify the batch file to make it work with the newer firmware
XT1922-5_ALJETER_RETLA_8.0.0_OPP27.91-143_cid50_subsidy-DEFAULT_regulatory-XT1922-5_CFC.xml
?
Thank you in advance!
