Report Requirements:
What NOT to report:
1. ANYTHING not on this ROM
2. ANYTHING on non-latest build
3. ANYTHING if you flashed any of following: [other kernel]/[Magisk]/[modules]/[other thing related to change system behavior], exception could be made if you are a developer of above
4. ANYTHING you need to know that written on FAQ
How to report correctly:
1. Describe how to reproduce
2. Take a log&dmesg AFTER the issue is triggered FAST then attach them to report
* For logcat tutorial, check:
https://wiki.lineageos.org/how-to/logcat
* For dmesg tutorial, use following commands on PC:
adb root
adb shell dmesg
You may get ignored for incorrect reporting
FAQ:
1. What is 13 / 13 (Plus edition)?
The 13 (Plus Edition) NOT means it's for pad 4+, It's PE+, the 13、13 (Plus edition) both available for Mi Pad 4/4+. PixelExperience Plus will have more custom features.
Also, if you are already on normal edition, you can directly dirty flash the same date plus edition or newer plus edition.
2. Why there is always a {"Press any key to shutdown"/fastboot cmd error(like send size error something else} on PC when I try to do something in bootloader like flashing a recovery/unlocking bootloader?
Your USB port on your PC, your cable and your device is not matched. Like Mi Pad 4 is USB 2.0 but you connect to a PC with USB 3.X on that(Usually laptop user). Change your usb setup to match it same: PC USB2.0 cable USB2.0. Or you may google for USB3.0 Reg patch for xiaomi(like this:
).
* Of course, I assume you are using latest usb and fastboot driver. If not, do that first.
3. How to flash certain partition with pe recovery? (like boot, frp, recovery, persist)
Use following command in bootloader mode
fastboot flash partition_name partition_name.img
OR
In pe recovery:
Advanced - enable adb
Then On PC:
adb push partition_name.img /tmp
adb shell
dd if=/tmp/partition_name.img of=/dev/block/bootdevice/by-name/partition_name
4. Why I lost all my sensor/can't rotate screen after flash/time always go wrong after a while(For NO SIM card)/can't use fingerprint as HOME BUTTON/any other weird issue?
* First of all, ROM has been tested without those issue from multiple user and myself, if you encountered any, check the info below:
Clover has a fragile persist partition, sometime it will break and cause these syndrome after a rom flash.
It's not only happen when you flash pe, but flash(change) any rom(including flash from LineageOS to MIUI or any combination). To recover, just flash a persist.img backup. However in this stage, if this device has been flashed to a non original backup(means not a backup when this deivce is good) of persist(may not by you but by the one you bought it from,
like second handed), it will recover the sensor, but breaks some other function lile RTC timer(
resets a wrong time on every RTC sync), real MAC address, HOME BUTTON on fingerprint, ...,
so unless you can't find anyway to recover the ORIGINAL one, DON'T flash the back up from others!!!(I did experiment for flashing others' backup, test then flash back to my original one, this is NOT assumption)
Here are methods to try:
[ONLY WORK when you or some other not flashed other's backup, again may not done by you but if you got this device from
second hand market, the previous men may do it,
ONCE persist is done flashing others, no way back as xiaomi did not provide any fix method for clover] Here are the methods:
Method Recommended: Flash your own persist partition backup(persist.img) is best which is backed up when everything is working then you will be fine, Steps below, if you sure you have done your own backup of persist.img, you can skip to step 2 or you can just go through this whole process to see if it can recover without touching persist manually.
Step 1. How to if I have no any backup of it?
First: go pe recovery -> Factory reset -> Format Data this is for flashing back to other ROM.
Second: try flash the ROM which used to be working, eg. you are from lineageos or miui, then go lineageos or miui, please used the method that required by that ROM(like flash to their twrp or use miflash etc) to flash it back, remember to not boot to the PE but complete this whole process in recovery/fastboot once you have done the "First" section's steps.
* Somebody told me that full flash back to MIUI 9.6.4 or earlier is an always working method, I never tried
Third: boot the system and check if everything is back, like the sensor(auto rotation, etc...), if time can be saved after rebooting, etc... If everything is not back, try miflash MIUI 9.6.4 or earlier package and check again.
Fourth: Now with everything back, do the backup process
- Root your device
- On pc with command "adb shell" or directly on the pad install a terminal app
- Use the backup commands in pc shell or terminal app like below:
su
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
- Now you can see there is a persist.img file in your internal storage, pull it to your computer and keep it
Step 2. Go flash pe again, check if everything breaks again(this may happen, not breaks every time, I have explained above), flash the persist backup use the FAQ#3 command
------------Please try previous first before you give up and try the "
Destructive" below!!!
Method Destructive: you can also download from others like from other's persist backup(
this will fix the sensor but also will change the real MAC, cause RTC timer incorrect(resets a wrong time on every reboot or every RTC sync) for your device, causing other weird problem) on xda post(like this:
https://xdaforums.com/t/rom-13-clov...omi-mi-pad-4-unofficial.4514507/post-88228039), thanks ichigo_kurosaki), for the flashing instruction please check the #3 FAQ above.
5. How to root with Magisk/Can PE run kernelsu?
Magisk: rename Magisk.apk to Magisk.zip then sideload it in recovery like the ROM or do it from a sdcard/usb otg in the recovery. Also, patch the boot.img from the ROM package then flash patched boot.img through fastboot or recovery is ok(check FAQ#3)
Kernel SU: NEVER from me, it's not so good, I don't like it and is banned from PE. By the way if you flashed other kernel for that you will lose the right to report ANYTHING(Check "Report requirements" section).
