Where can i find repair_persist-willow.zip ? From gingko not work.

maybe extract it from"" fastboot.tgz""which your original version use

 

[Kodize]

You are my hero, thank you! I tried the telegram solution with a command in the terminal and it didn't work, I tried reinstalling the rom by fastboot and it didn't work either, my sensor was practically dead and I recovered it by flashing your persist.img, infinite grace!

i think you should flash the special “persist.img” from yourself original rom。
for example：your original firmware version come from Android9.0，your must flash that persist.img from the 9.0 official firmware
and this tips for you：flash this img over android platform tools
may your phone come to the normal

Download the fastboot ROM for your phone and find the persist.img. These zips are made for ginkgo.

Find the persist.img form your fastboot ROM. Then replace the persist.img in the zip file.

Everyone knows that the persist partition is responsible for sonsors and carrier network etc. Once this partition is failed or lost, your phone will go wrong. I just faced, then solved the problem and I want to share the solution that could maybe help other persons.

This was how it happeded:
While I was flashing the phone, I erased the partition called "persist" accidently. When I was trying to flash the persist partition, the phone returned a message said that you can't flash the controlled partition. I suddenly relized something bad happened. Then I reboot the phone and find that many sensors stopped working. But the worst thing is the carrier network signals lost. I want to contact the service center at first. But I think as long as the phone is unlocked, there are tons of possibilities to fix it, unless it's hard-bricked. So I wanted to try to fix the partition.

As we know, Xiaomi phones have backup partitions for most of the important partitions. For example, vbmeta and vbmetabak partitions. The vbmetabak usually is the backup of vbmeta. This persist partition also has a backup partition called "persistbak". This backup partition can be used to repair the persist partition. There are 2 ways to fix the persist partition. Choose the method you preferred.


1. This way is for users have erased the persist partition, but haven't modified/erased the persistbak partition. If you don't want to type commands just use method 2.
Go to fastboot, flash the twrp recovery first. Then hold the POWER and VOLUME UP to force the phone boot to twrp recovery. Connect the phone to your PC and open adb command window. Type the following commands in order:

adb shell

cd /dev/block/by-name

ls -all

Check the output, find the partitions called "persist" and "persistbak". Remember the blocks corresponding to these two partitions. They should be similar to "mmcblk0p**". Once you know these correspondences, you can restore the persist partition immediately. For example, the persist partition and persistbak partition correspond to mmcblk0p$$ and mmcblk0p%% respectively (persist---->mmcblk0p$$ and persistbak---->mmcblk0p%%). Run this following command to restore your persist partition:

dd if=/dev/block/mmcblk0p%% of=/dev/block/mmcblk0p$$

Note: You need to replace "mmcblk0p$$" and "mmcblk0p%%" with the real partition block name.

Now the persist partition has been fixed/restored. Reboot your phone to system and check whether sensors and carrier network etc. all work fine.


2. This way is for users that have erased persist partition and persistbak partition or can't restore the partition using method 1. Also, this method is a universal and easy way to fix both persist partition and persistbak partition. It doesn't need to type any command but only a swipe.
I have made the persist partition repair tool for both global version and Chinese version. Both of them are in attachments. These tools make the repair process very easy. Both flashable zip files are tested on my Redmi Note 8 and they work fine.
I have also posted them to Mi Community.
Flash the repair tool in attachment. Choose the right file and flash it.
Now the persist partition and persistbak partition have been fixed/restored. Reboot your phone to system and check whether sensors and carrier network etc. all work fine.

I'm in another huge problem trying to fix that one. I flashed the official firmware on my redmi note 5 (Vince), then It restarts automatically(It's like when u hold the power button for too long). I tried removing the power and volume strip to check if the problem was because of the buttons, still have the same issue. please help

Hi Yuki,

Greetings from India, hope you and your family are doing well.

I own a Redmi K20 (davinci). I had installed Pixel Experience rom, which I didn't like and wanted to roll back to stock rom. But without reading the guide to flash fastboot rom, I flashed the back up I had taken via TWRP. Apparently, my phone was bricked and I had to enter edl mode via cmd and flash the stock rom which showed some error, but the phone booted to stock rom. Everything is working fine, even the touch-fingerprint sensor is working. All the other sensors aren't. I tried a lot of things, but to no avail. I took my device to the official service centre, they couldn't fix the sensors' issue.

A couple of days ago, I stumbled upon your post on Redmi 8-sensors-not-issue solution. Can I use the same tool to fix the persist partition on my phone? I had read one of your replies saying: specific phone's persist.img should be extracted from the fastboot rom and replaced with one in your tool.

It would be a great help if you could guide me.

Many thanks
