[Android Q&A, Help & Troubleshooting] Knochlet:
Hello all together,

i´ve got an Xiaomi Redmi 4 Prime (3G/32GB) FullHD Smartphone which i was very happy the last 3 years. It worked smooth and i had a great experience. Every evening when i go to bed, i shut down the phone and reboot it in the morning. So i did one week before. But on next morning phone does not boot any more. It was stuck on MI Logo.

I could not do ANYTHING.

Could not even remove battery because it is not removable. All i could do is to wait until fully charged battery did go down to 0%.

So i tried rebooting many time without success. Looking at the internet i found some users reporting same problem, but most did have problems after an update or flashing or something. My Phone is Stock, i ordered it from china and never flashed anything. I did have Google Play Store and good working OS (Android 6.0 and MIUI 8). In the phone itself i often tried to look for updates but all time it told me i am up to date. i didn´t care about having an old OS. It was working and ok for me.

Ok so i did do alot of searches in google and found some instructions like how to boot into recovery mode or how to boot into fastboot mode.

As a software developer, i already had Android Studio on my machine and i did try to use the platform-tools from the SDK (adb.exe and fastboot.exe)

After some drivers update i can tell if iam in recovery mode, adb is listing my device

so when i type "adb devices" i get

i did try a "adb pull /sdcard" but i get error: connection failed: closed

so i tried with fastboot

i found some information like booting twrp like a live cd with fastboot boot twrp.img (i did download a twrp version from the internet)

but i had no success and got that message

i tried fastboot erase cache, this seem to be worked, but my phone does not boot :rolleyes:

fastboot oem device-info is giving me this info

fastboot getvar all

So now WHAT I WANT!!!

I want to boot my phone to like it was WITHOUT loosing ANY DATA.

or at LEAST, recover the FILES from the internal 32GB storage.

I have WhatsApp Conversation and Media Files from near 4 years which i don´t want to miss.

I´ll be thankfully for every help i get from you. Please, before that trouble i have now, i never used adb, fastboot, twrp or anything like that before.

But why does it not boot any more, i just powered it off :confused::(

Maybe the internal storage is near full, that is the only reason i could think. so erasing some files might help

For this guy who can help me to reboot my phone without loosing any data in it i will even donate some bucks via paypal to you.:fingers-crossed:
