Persist - Xiaomi Poco F2 Pro (Redmi K30 Pro) Questions & Ans

Hello,
i did a transcript persist.img since then my fingerprint doesn't work. Unfortunately I did not make a backup backuppersist.img Please, if any of you here do not have persist.img functional or some other advice.
Thank you very much.

Download fastboot rom here https://xiaomifirmwareupdater.com/archive/miui/lmi/and extract it.

I tried Global and EEA doesn't work.

Flash to EEA ROM and then calibration it already works. Thanks a lot.

Probably you loose Widevine L1 also.

I lost my fingerprint too,find my thread about that and how to fix it.
There is no need to flash ROM.
Just go and tap couple times to kernel to open CIT test, ind the right corner go to additional setting and find fingerprint option,find something black ,paper ,white , to cover sensors.. follow instructions..its simple..and your fingerprint will be back

For me, the fingerprint calibration on the Xiaomi.eu ROM did not work. Because of this, I first made a flash on the EEA ROM and then calibrated the fingerprint.

I uploaded my backup. You can try it, maybe it will help.

I fix mine with calibration but did you try this one in advanced setting? In CIT?
Because if you not try this in advanced setting the first one will nor working..and you will not be able to fix it and pass

Make G360H Superfast! Lagness SOLVED & Performance IMPROVED!

Hi,
We all felt problem of LAGGNESS and PERFORMANCE from our beast after flashing the custom ROMs. No way problems could not be solved although flashing official stock ROM through odin.
HERE HOW TO SOLVE THE PROBLEMS.
First of all you have to download Smart Switch( Official PC suite)
and then simple flash ROM through the suite. DONE af
Just download SMART SWITCH from http://www.samsung.com/in/support/smartswitch/ to your pc.
BOOT your phone to DOWNLOAD mode [power+volume down+home key while phone in switched off mode]
Go to smart switch and press EMERGENCY SOFTWARE RECOVERY AND ... & follow the instruction.
Done!!!!!
HOPE UR PROBLEM WILL BE SOLVED LIKE ME
------------------------------------------------------
I have not yet install any CUSTOM ROM. So don"t know about performance in Custom ROM. If u have tried pls report asap.
I recommend INSTALL RR 6.0 (Only big problem is networkstabilty, others are okay).

I did it and installed rr 6.0 and its smooth as ****(at least for now) and so you can add to the thread that roms work and the method works too
Can I use the tar.md5 file in this tool also?? Like Odin?
Doesn't work. If you have flashed ANY THING on your out-of-the-box firmware, it will give you lag whether you flash/format and reinstall STOCK rom. If you can feel the smoothness again, don't get too excited, the lag will come again within 15 days.
Once you flash there is no going back.
It just install the very first firmware of the phone. This won't make difference tho

Since I can't post my feedback to hashtag new PAC ROM I wrote it here instead. So I just flash it in a clean way. From clearing system and all and back to stock install root kernel then twrp then flash the PAC ROM clean way. And after testing
And it takes I thing more than 30mins to flash the ROM. And after testing the ROM is extremely laggy and I found resurrection remix way smoother than the new PAC ROM

Wipe and flash, lol. Cp is ?
Bro it's crap
This only reflash the firmware. As soon as there are apps, the phone will get laggy. So don't be excited.
Placebo. There's no reason a why a wipe makes device lagfree except for the first few hours..

Please note phone will be faster as you new phone you have bought. (Later lag, that's blame SAMSUNG)
Hay.i have an idea. . . .i tryed it and it works for me, . .go try your self.but you will lost your data.so backup 1st.
1st step=>you nead stock rom,
2nd step=>go to stock recovery and do wipe and factry reset several time(3-5),
3rd and last step=>go to setings and do a factry reset from there,
After 3rd step you will feel the light of the rom like 1st day you buy it.!

[SOLVED] Downgrade B560 to B320 or other marshmallow ROM

Hi,
I have just buy a mate 8, and it was already on NXT-L29C432B560.
What I want to do is downgrade to Marshmallow for install Xposed.
But I'm not sure about the way to do that. Can I just put a NXT-L29-B320 on the phone and flash it the TWR ?
Actually I plan to install this one :
https://forum.xda-developers.com/mate-8/development/rom-stock-b162-rooted-t3336931
But if you have any advices about another ROM who could be a better choise I'm hearing you.

If your phone model is european, I've a rollback package for C432B560 on my Home-PC.. . If you want to I can upload it anywhere. But tonight!
Thanks Franzyboy, it's very helpfull, I confess than I'm a little bit lost at this point.
It will be nice if you can upload this
I will do some search on my side to see if I can't find this firmware by myself, I'll let you know if I do.

I've found the C432B560 files, but in fact I can find the c432B320 for marshmallow, by any chance have you also this file ?
UPDATE : In fact the C432B560 I have doesn't work, recovery fail after 5%... So I'm still interested but your files

Are you currently on Mate 8, which ROM do you use ?
I received mine yesterday, but the last owner of the device, it does an unclean install of the ROM, no keybord just google voice input and no bluetooth anymore. I hope I'll can solve the prob

To fix your issue, there is another solution.
Install your firmware via dload - the one you have now.
@franzyroy
it's that I try to do, but when I try to flash with "dload" method, it fails at 5%, and I really need bluetooth. Maybe I could try with an higher version of the firmware what do you think ?
How have you tweak your rom ? The thing I really want is to change the dpi setting (don't need a huge screen for big icones...), I've seen a method with adb, but for me it only work before I restart the phone.

I forgot, like you are with the B560, you can't install lower. You have to make a rollback to have the B320.
No tweaks but use some scripts to have the double tap by example. You also have a script for the icons size.

And if I try to install again the C432B560 how I have to proced ?
In fact this ROM isn't bad, but I really need the bluetooth, and I hope a clean install can solve the prob. But when I try to install the C432B560, it always fail at 5%...

Your experience with the bluetooth is the problem of lot of people. For certains, it was due to the root. But there, not your case. I don't see!
Did you install the both files? update.zip and update-data.zip.
update-data.zip
I havn't install this files cause I don't have it. Where can I find it ?

I was able to correct the error by downloading the global fastboot rom, extracting it and copying the file persist.img, then giving flash in TWRP corrected the problem.

all sensors not working after customer care flash rom

I have stock rom on my Oneplus 6. After the new OTA update 9.0.5 it downloads (aprrox 94 Mb) but installation failed. After 2 tries it says download full rom. then I rebooted my device, It stuck into fastboot mode. I called customer care they flashed the device remotely, now device is booted normally but all sensors are not working like proximity, autorotate etc. by dialing *#808# engineering menu tries to self-test & calibrate sensors but it shows only grey screen. Also sensor test & CPU-z app from play store also not showing any sensors.
dear members is it possible that flashing currupted my sensor files in system, could it possible to flash sensor file.
I tried to downgrade to 9.0.4 via update from local, says downgrade not possible. I tried Beta 16 update , problem still persist.
help me guys ASAP.

I think you have a faulty phone now. Probably why you had a problem to start with. Msm takes you back to factory reset. Should work but if the problem is still there looks like its hardware. ?

fingerprint sensor error poco f2 pro

Hello
Has anyone encountered this fingerprint reader problem?
I can't read the fingerprint!
Global Poco F2 Pro 6/128
ROM: lmi_eea_global_images_V12.0.3.0.QJKEUXM_20200923.0000.00_10.0_eea_e53e1f2537
Bootloader closed.
https://ibb.co/z6tymgq
I had great difficulty identifying the fingerprint and failed several times
Go to CIT , tap couple times on kernel to enter CIT test, in up right corner you have three dots, press on it to be able to enter advanced settings.
This is very important!!
You must enter advanced settings, and go to fingerprint options, you need black paper and white for test, when you finish it,you will get your fingerprint back.
Find my post, tou will see the same thread with this problem and how I solved it

Thanks for the reply!
Do you describe exactly how to do it?
I'm an amateur.
I can start if you describe exactly how to get started.
First to the menu using * # * # 6484 # * # *, then 3 dots on the top right and tools
The choice is the 12th fingerprint calibration
At first, the calibration is against a light surface, but a mirror is recommended (usually you attach it to a fingerprint reader). Then the calibration is against a dark surface. After that restart the phone.

I got a mistake here too!
I only have a problem with my right thumb but it is a problem with my finger and not with the sensor since with any other finger I know it immediately (LOL)
The only problem for me is not that it doesn’t solve it.
The problem is that I can't scan the fingerprint!
I only have a pin, pattern, and password option.

You said you tried several rom so you unlocked the bootloader?
I find it strange that when you bought it it was already in V12.0.3.0.QJKEUXM.
Are you sure that this is not a K30 pro modify to F2 pro?

If I remember correctly the V12.0.2.0.QJKEUXM Rom was on it when I bought it.
Here I opened and then put the EU.dev Rom system on it.
I tried the fingerprint reader on this first, but it didn’t go.
After that I tried a lot, but the mem still doesn't work.
