Just (finally) upgraded to android 8.1.
I had to use adb to uninstall "factorymode" to get rid of the red "tee key".
I waited this long because i wasn't verry confident it would work.
It's a shame Ulefone didn't provide a OTA for this.
I moved on to a Redmi note 7, and save the Ulefone as backup.
The friend tells me the step by step exactly of this procedure because I have the same problem but I don't know how to get these red descriptions.
how you fixed battery drain wit this rom? i mean wit oreo 8.1 android
hello all,not sure i will get answer but need to ask,this rom have updates or no? because i installed him already but got huge battery drain.
V12 is the latest update. Do not expect any more updates from Ulefone for this model.
It's only with me or this ROM cannot use the Camera and the fingerprint sensor ?
For Nandoinet and other ptbr users: Consegui instalar , usar normalmentem mas o sensor de digital não funfa nem ferrando, tirar esse tee key é simples basta remover um apk factorymode, tem vários referencias nas net sobre isso e incluse neste site. O IMEI ficou de boa nesta ROM mas ao ligar a camera já reinicia essa budega, é de desanimar , e o botão power meu já ta veio não funciona direito preciso do sensor de .digital funcional , se pa vou ter q ficar preso no 7.1.1 até eu comprar outro celular kkkk
