[Q] Lenovo K920pro - Flash Chinese version to Google Version

[__ZOOM__]

Hi.
I work in China ow and then and i bought my self a Lenovo K920 yesterday. A GREAT phone but sadly the it does not have any Google programs/system but just a similar Chinese system which i know nothing about. I have found some ROMs out there but on some forum people warns about flashing the Chinese K920pro as it will brick.

Any one here who could tell me how to proceed.... Thanks

There's a video showing how to unlock the developer option in settings and the switch to Google UI is inside the Developer Option. Looks quite awesome, im gonna own this phone later.

Yes, i read about this too..... I have the Developer Option available already (a few taps on the version number) but no Google UI option there, just 3 options to chose from. Or do you know how to get more options?

I did a try a russian "2014-10-14--10-16-45 K920_ROW_S126_140825.7z" with their "twrp_2.8.0.1_r​ecovery_K920Pr​o.7z" file but it "killed" my phone....

I can still access the Lenovo Re ovey and the root menu though.. But the operating system just hangs at the Chinese 4G logo.....

Im not able to restart the TWRP again. I start to dislike this odd phone now after spending 30-40 hours to try to get google play, gmail etc to work.. I should have bought a HTC or Samsung instead..

You shouldn't do that at the early release of the phone. Even any phone. You need to wait for the official rom release. How about you try fastboot and flash the twrp/cwm recovery. From the recovery use sideload to reflash the stock rom. Keep in mind that you should wait for a review or someone who actually successfully flash the custom roms/non-official rom. Except root, theres a number of successful root.

I know but i was desperate to get Google to work... Bricked or Chines system is same same for me...

Fastboot and TWRP cant find any device. Factory reset or wipe did not help either. Can access boot menu and Lenovo recovery, but need a recovery file first, and then we have problem with that i cant access the phones internal storage.... And this crap has no SD-memory either...
$700 down the drain for sure... Still have to buy a new phone though, and im still in China... Have to fly to HK to get a new phone... This is going to be expensive.

Thats what happen when you flash the unofficial rom. You know the risk. Make sure you have installed fastboot driver and adb driver. Im sure you can reflash the rom after you able to enter fastboot

Drivers are okay and have worked before. But now when running ABD Devices command, it show "? unautorized" so i get stuck there.

I SOLVED IT....... Except that the both SIM-card shows a red X.. but everything else seems, camera, GPS, WiFi to work AND it has GOODLE PLAY etc now.. Anyone know how to make the phone to work again?

I have tried ABD, Fastboot, TWRP, MiFlash, QPST, QMSCT_DL_EMMC_TOOL but nothing worked except following this instruction

I used the files in the Bin-folder of K920_ROW_S126_140825_user_1408251128 rom

Slightly different hardware and radio modules.
On lenovo forum there is something about radio calibration.

of course it works otherwise i wouldnt post the solution.After you flash the rom everything works flawlessly but dont update ota to the latest version because you will lose the radio again.
