I'm beyond frustration. Been trying to install this build on my lumia 1520 since day one and its weekend already and I'm still stuck. Only twice i was successful but again it all went haywire. I'll explain why below.
Some info about my phone:
OS: Windows Phone 8.1 GDR2.
Memory Card: 64gb SanDisk Pro
ROM: Indian ROM.
To enable cortana i had to keep following settings.
Region:US
Language: English US
Speech: English US
Time: India GMT +5:30
1) Day one of the new build, i was on Indian ROM updated to build gdr2. Checked the updates and got some update, installed and everything went smoothly. But I got build 84 instead. There was no further update after i used the check updates option multiple times.So it was time to flash a clean ROM of 8.1 and proceed as instructed in the blog.
2) I flashed a clean rom, allowed it to updated whatever apps it wanted to, installed the critical update regarding reboots and then installed windows insider, signed up for the fast ring and restarted. Voila, i got the latest build to download. Now comes the trouble, after about 60% bar in spinning gears stage, it restarted and showed a red battery sign. I plugged in the charger (even though phone was at 65% before gears started spinning), then it got into a bootloop of spinning gears and restarts.
I flashed a clean rom again and when phone started it still had around 53% battery. WTF. I still thought it was my fault. So i charged the phone to 100% and then repeated the steps above. No change, same spinning gears.
3) Did these steps atleast 15 times over last few days with different variations. Sometimes without sim, sometime without SD card, sometime without both but everytime it either gets into the bootloop or after a few bootloops it reboots back into windows phone 8.1 and displays error 0x80070057.
4) Only two times i got success : I dont know if i got lucky or what thus trying to retrace those steps exactly while I'm writing this. I had set the region, language and speech to default. Skipped the critical update by keeping Wifi off and automatic check of updates. Then installed Windows Insider and quickly rebooted to get just the preview build. It got installed successfully. First time i found the UI little sluggish so i did a hard reset to fix it and it got into bootloop during the hard reset. Even though UI was sluggish but i was getting some update in the update option but my wifi was acting up so i couldnt download it.
second time(few hours back) when i succeeded using these steps, I was not getting any update in update option. And was not able to download any language pack. There was some error everytime. Thus i did a hard reset. This time it didnt got stuck in hard reset but still i was not able to download the language packs to get the cortana working. So i decided to flash it again but for some reason i was cocky and instead of following these exact steps, I downloaded the US language pack and US keyboard in 8.1 and set them default. Again got the bootloop while flashing the preview build.
Now I'm trying to follow the steps i followed to got success twice to see if they get me somewhere.
There was also one of thing that was common in two successful installs of windows 10. Both were possible when i was in my office where they keep it pretty damn cold for some weird reason. At home phones were getting really hot during windows 10 installation and sometimes they were restarting and showing that red battery sign before the progress bar in installation reached 40% and sometime 80%. So I'm beginning to think maybe overheating is somehow kicking some kind of thermal protection which is causing phone to restart. Or maybe the battery is getting affected by heat and unable to provide enough juice for the installation.
So for this next installation, I'm gonna reduce the room temperature to similar to what i have in office and see what happens.
Any suggestions or tips are wellcome. I'm open to anything at this point. Even calling ghosthunters or witchers is a viable idea as of now :crying:
