hotknot ? camera 8mp and 9.5mp ? when activate sound effect in music player the phone lock and need restart,sound ringtone or media is weak.look good but not i like totally.need more work.thanx.
I'm having trouble getting SP Flash Tool to recognise my phone – when I plug it in via usb cable (phone turned off and holding vol up button) my laptop sees it and makes a noise but Flash Tools just waits and waits and never sees the phone.
I've installed the drivers manually so they should be up to date, can anyone help?
Rom has been instaled and it is very pretty and run smoothly so far.
The only problem that i have found is the camera, It now shows 8 MP for the Rear Cam and 9.5 MP for the front Cam.
Any solution so far?
Thanks for the Rom
it don't matches.
I follow the written procedure, but download wouldnt begin.
When i let the Vol up go, Battery begin to charge, if i hold vol up longer, phone ask for "select boot mode".
i have tried procedure with and without batterie. Where is the mistake?
thanks for help and answer
same problem
Since the update is hotknot away .
This is currently what strikes me
My Phone was Rootet , is root away after Upgrading to 5.1?
My UMI Hammer Android 5.1 works well with androidroot. Unlike the other rooting software it failed.
I'm not able to do this part, just hold the button VOL UP and does not happen anything.
"- Now connect your phone into the computer via USB data cable, while you hold VOL UP button down

Please help.
The ROM is okay, many thanks for it!
I could install XPosed Framework (xposed-v75-sdk22-arm64.zip and XposedInstaller_3.0_alpha4.apk from here),
XPrivacy and GravityBox work fine.
The cons:
- no USB notification, hence no file transfer, no ADB !!! (It works in recovery – @bigrammy's TWRP)
- camera quality suffered, slightly improved with open camera
- no smart wake functions
- no HotKnot
But we all are still waiting for a truly official update issued by UMI themselves, aren't we?
i get a red progres bar at the bottum, but it stays red. whit the text download da 100%. i waited 1 hour.
