Okay so for me it went a bit different. First of all i flashed from SD card from common 1.1 android 5.0.2 directly to 2.5 android 5.1 with android recovery. It worked and even it didn't wiped out all my data but for some reason it destroyed the android recovery. When trying to access it with normal gesture (volume up + Power button) Innos logo was just blinking and the screen went black but the phone was not off (if i plug it in USB the PC recognize it).
Anyway, i just did as the tutorial say on this page, but couldn't do it from recovery mode, so i figured i could maybe do it from android booted. Problem is, i couldn't unlcock the bootloader with "fastboot OEM unlock-go", it says "waiting for device" (obviously because i was not in bootloader mode) so instead of doing this first i just launched Run_test.bat and it did recognized the device, then just force restarted it into bootloader. The trick is, if i just press random keys to continue the test it will fail because the bootloader is not unlocked, so immediatly after the phone restart to bootloader i launched the "fastboot OEM unlock-go" command from another cmd window. And it worked !
But sadly when the temporary TWRP start it immediatly detect something wrong with the partition or something (i think because what i did before to update to 5.1) and auto restart in 5 seconds, so i couldn't do anything. After that the phone looked stuck on innos logo, the camel didn't show up for like 10 minutes and when it did all my data was deleted and the phone was in chinese (5.1 and 2.5).
Luckily i did backup so everything was okay. I ran TWRP again but this time i could use the Android recovery mode.
I flashed one after another Permanent TWRP, gApps, superSU then rebooted the phone. Now it seems to be okay, i am installing all my apps from google play store and that's all i wanted.
I hope it will help if anyone got the same problem with the recovery.
