Immediately after deleted I switched off wifi and mobile data to avoid incoming msg/mail/whatsapp. For Pandora(now named as Disk Drill, free version can recover 500MB only ) and needs to install on Windows PC.

To connect RN4 via USB and used as an external drive:
Do I need to root my RN4?
Do I need to enable USB Debugging on RN4?

After reading the reviews of the recovery tools most are bad or with limited result.

I tested using another phone(RN3) by deleting most photos(after backup) in the Gallery and the use Google Photo app to backup and sync and surprisingly all those I deleted were also backup to the Google cloud. But it works only partially for my RN4.

Would probably try using Recuva but too bad Recuva can't detect the RN4 as an external drive but has to be done in this elaborate manner:

Here’s the algorithm for Android internal storage recovery:

Make a copy of the internal memory partition (as a RAW file),
Convert RAW to VHD format,
Connect the virtual Hard Drive to the filesystem via Disk Management,
Scan virtual hard drive using recovery soft,
Restore files from the copy of internal storage.

CAn the PC connected to the RN5 treat it as an external drive, so that I can use Recovery software like REcuva to undelete all my photos and videos?

Looks like most of the recovery software needs the affected RN4 to be rooted for effective recovery of the deleted photos in the Gallery. Pls advise me b4 I proceed with this:
1. Unlocking the RN4 takes how many days and need to request thru Mi account?
2. What is the function of "Mi Unlock Status" in Developer Option?
3. Is Kingroot safe n effective in rooting RN4? According to a youtube video it is simple to use.
4. I manage to list the content of the RN4 using Windows Explorer but when using Recuva it doesnt detect it as a drive but I can transfer the RN4's content to the PC. The RN4 is in USB debugging mode but not rooted yet.

Photos were deleted accidentally from the gallery of Redmi Note 4 phone 2 weeks ago. Havent been using the phone since cos looking for solution.


Anyone has tried this to recover deleted photos from gellary in RN4?

Is it safe to use such method as it will root the phone b4 recovering and then unroot once finishes?

According to says dot-com RN5 has one of the highest radiation.

Posted this in RN4 thread but didnt get much reply, hope can get help from here:

My Malaysian set RN4x is unable to switch on or boot, only red light keeps blinking during charging. Google and it seems like a common problem but different way of rectifications. So far tried a few but not working.

After trying the different self diagnosis suggested by google, my 18months old RN4 still cannot be charged or boot. Brought to Xiaomi Authorised service center to diagnose and was told problem with mainboard, so not worth repairing n paid rm25 for that. My 3year old RN3 still kicking strong.

The xiaomi authorized service center said my phone is gone and data not retrievable. But when I brought to another shop, tested my battery ok but still can't charge and can't switched on, dismantled the battery n powered d phone directly by charger n phone can be switched on and booted, everything still intact felt relieved.
At least now allowed me to savage my data. Will backup all data b4 repairing the shorted mainboard, repairing cost btw rm150-rm250.

Useless xiaomi service center charged me rm25 for a lousy job.

WTA:
1) Is it safe to continue using the shorted phone with direct power while backup the data and reset it to factory setting?
2) Is the repair cost of 150-250 which takes 2 hours too high?
3) Normally would repaired unit last >1 year?

Any opinion is welcome.

Since my RN4 is not working with the internal battery and if I dont get my mainboard repaired, may be I should get a clip-on power bank like this:

I tot this external powerbank could be charged directly by charger, need to make sure.

p/s U are right, have to look for something else like a clip-on powerbank which is chargeable externally by charger

Currently it works with any normal power bank just that it is messy with the usb cable n ugly, those external battery case looks better. Phone doesn't work with internal battery but works if powered from usb, either direct from charger or power bank.

RN7 GPS problem?

My RN3 hang so I pressed on the power button to reboot but now it is stuck at the Mi logo and the powered by Android logo with the 3 moving dots.
Anyone can help?

I held down the power button until it buzz and let go, but it still stuck at the Mi logo and Powered by Android logo and 3 dots.

You meant u let it stuck at the Mi logo and Powered by Android logo for several hours before finally holding down the power button for a long time?

Can I go into recovery mode and then reboot from there?
Or clear cache while in recovery mode? Would this affect my apps, photos and data?

edit: can't even get into both Fastboot mode(Vol-down + Power) or Recovery mode(Vol-up + Power). When I did this, the logo went off and a 0% battery with a charging connector was displayed.
