[URGENT] Stuck at Android logo - Not booting - Can't factory reset.

hades

My phone's battery got fully discharged today and then the phone didn't turn on after that. I've tried charging it quite a few times after that but it doesn't really charge (I don't see the red notification LED light that tells whether the phone is charging or not).

The back isn't removable, so the battery can't be removed. I can open it but that would take too much effort and I might fuck something else up.

I pressed Volume Up + Power button to go and factory reset the phone but it only showed 3 options -
Recovery Mode
Fastboot Mode
Normal Boot

So couldn't find the factory reset option. Also tried the above 3 options but none of them worked. Recovery Mode gives error Sin Comandos and Fastboot Mode does nothing and Normal boot stucks at Android logo.

I would love some help right now, I'd appreciate it very much.

Edit: I have a feeling that I corrupted my OS. I was playing with Rootjoy a little yesterday. How do I fix this if my OS is corrupted?

Thank you! I will try to do that now. Can I flash Flyme OS made for UMi Iron or is it safer to do the stock UMi one?

If you've bricked your phone, you still can reinstate it with SP Flash Tool. You can find the latest version here: http://community.umidigi.com/thread-1655-1-1.html
Before proceeding, get through the tutorials and be very careful if you do it at the first time. Never choose the 'Format All + Download' option.

I suggest you to recover your phone with a stock ROM. If that works well, then you may update with a custom ROM.

Keep calm!!!!
Connect your Iron to charger and wait... MINUTES... ¿10-15...?
Only then you will see:
red led and empty battery logo...
after 0-1% battery logo...
wait until 5-10%...
and then turn ON normally!!!

Maybe... when you press buttons while start+charge process
you are playing "Grey Raster Egg"
;-DD

\n\nThe tutorial says my phone needs to be 40-50% charged but I can't charge it, charging isn't working, what do I do now?

Charging isn't working, PelaMartinez.
The v1.8 rar provided seems to be corrupt. Going to download v1.7 now to see if it works.

If there isn't a working bootloader on the phone, the charging process can't start. In that case you have to remove the battery and charge it with an external charger.
On the v1.8 ROM page the downloadable ROM file is a zip archive, not rar and anyway all files are intact, no one of them is corrupted.

I seem to have a problem with Mediafire. Is there any way you could upload it to another website, perhaps Zippyshare or tell me another ROM I can do?

I am really worried, my phone has been off since 3 days now and I am not able to do anything about it. Thank you for help.
