OK, one update - I was using stock rom leak 4.1.2.
What I've done.
I've created Slot 2 in SS (3.11) and installed here this rom - Jelly Bean 982.124.14.XT910.Retail.en.AU IMPROVED LIGHT
Next I did backup of it and tried to restore it in Stock slot.
Result - bootloop.
Next thing I tried is to install all soft from beginning and enter AP Fastboot mode without uninstalling SS.
I used firmware SPDREM_U_01.6.7.2-180_SPU-19-TA-11.6_SIGNEuropeAustraliaEMEA_USASPDRICSRTGB_HWp2b_ Service1FF_fastboot.xml.zip, which
was working previously.
Got error in RSD Lite (v6.1.4) - Failed flashing process. 1/10 flash cdt.bin "cdt.bin_signed" Phone return fail
Next I upgraded SS to 3.53 version and tried again to do backup slot 2 rom and restore it in stock.
Now stock is working with Jelly Bean 982.124.14.XT910.Retail.en.AU IMPROVED LIGHT, but after flashing failure with RDS Lite
every time when I'm booting phone get as first screen AP Fastboot with message - AP Fastboot Flash Mode (S) (Flash Failure)
When I power off phone and power on with pressing in the same time Vol- Vol+ Power I got Boot Mode Selection Menu (0A.77) and when I select mode: Normal PowerUp everything seems to work - I see next SS screen and stock slot is loading.
My question is how to get rid off that first screen with AP Fastboot?
Thanks in advance for any help.
This thread helped: [ FLASH ] Motorola Razr Flash Failure [ Solution ]
to get rid off that screen.
But anyway I'm just curious why RSD installation failed.
