Moto E XT1021 GB OMNI version - can't install any rom - Moto E Q&A, Help & Troubleshooting

Phone was replaced by Motorola to a new device - after motherboard bug. A new device is UK version.
I have unlocked it and installed recovery, but I can't install any rom - I've tried with CWM and TRWP (2 different versions).
Every try ends up with "ERROR 7". In error logs:
You have an installed system that isn't signed with this build's key, aborting...
run_program: child exited with status 124
script aborted: Can't install this package on top of incompatible data. Please try another package or run a factory reset

I've tried with:
aokp_condor_mm_nightly_2017-01-16
AospExtended-v3.1-condor-20170124-0102-OFFICIAL
lineage-14.1-20170119-UNOFFICIAL-condor
I found a solution for "Error 7" (remove first lines from update-script) but it doesn't help.
Similar problem I found here: http://www.androidpit.com.br/forum/...o-para-lollilop-da-erro-mesmo-sem-root/page/2
In my CWM log there was also something like:
Package expects build fingerprint of motorola/condor_retbr_ds/condor_umtsds:4.4.4/KXC21.5-40/49:user/release-keys or motorola/condor_retbr_ds/condor_umtsds:5.1/LPC23.13-34.8/12:user/release-keys; this device has Motorola/omni_condor/condor:4.4.2/KOT49H/eng.bigbiff.20140616.171951:eng/test-keys.

So the problem is "omni_condor" fingerprint of a device. Is it a different hardware then all other versions?
The fingerprint is also checked in update-script:
run_program("/tmp/install/bin/otasigcheck.sh") != "31744" || abort("Can't install this package on top of incompatible data. Please try another package or run a factory reset");

I can remove that lines and try to install system, but I don't want to brick it.
Any ideas? Do I need special version of CWM/TRWP or just need to "fix" update-script and it should work ok?

Official twrp causes problem with nougat ROMs ! Try squid twrp ( http://www.mediafire.com/file/ca3rjwh43qbzmw5/twrp-condor-3.0.2-r5.img ) and if you want to flash gapps then you should flash pico gapps .

Stock 5.1 with TRWP 3.0.2-r5 and still "error 7". It seems to be problem with fingerprint.
Looks like the only way to do it is to edit update-script and remove fingerprint check.
UPDATE/EDIT
After removing fingerprint check everything works ok - I can flash rom and it is working ok. Problem solved.

getprop("ro.build.fingerprint") == "motorola/condor_retaildsds/condor_umtsds:4.4.4/KXC21.5-40/46:user/release-keys" ||
getprop("ro.build.fingerprint") == "motorola/condor_retaildsds/condor_umtsds:5.0.2/LXC22.46-32/30:user/release-keys" ||
abort("Package expects build fingerprint of motorola/condor_retaildsds/condor_umtsds:4.4.4/KXC21.5-40/46:user/release-keys or motorola/condor_retaildsds/condor_umtsds:5.0.2/LXC22.46-32/30:user/release-keys; this device has " + getprop("ro.build.fingerprint") + ".");
