Downgrade - Xiaomi Poco F1 Questions & Answers

My Poco F1 is on latest official stable rom.
Is it possible to downgrade to V9.6.25.0.OEJMIFD?
My search did not find anything about downgrading from A10 to A8.1 version.
Thanks

To answer my own question, yes, it is possible.
I downgraded from latest official stable, 12.0.3.0.QEJMIXM, to 9.6.25.0.OEJMIFD.
I did get an error at the end of flashing process, but everything works fine.
I used official Xiaomi flashing tool and fastboot rom.

Hi Could you help me with any youtube/guide links for this process, as i found few.. but it would be great from a user who had done it already..
Thanks.

No links, download xiaomi flash tool, and desired fastboot version of oficial ROM.
For this to work You must have bootloader unlocked. There is also official tool for that.
Go to fastboot with phone, shutdovn, then power key + volume down, phone should appear int flashing tool.
Choose fastboot rom and flash. You can choose between bootloader lock or unlock.
Everything can be found via google, should not be a problem.
Of course, I am not responsible if You cause damage to Your phone.

Can't root redmi note 3 Snapdragon

I have the Redmi note 3 pro 2gb snapdragon version I have unlocked my bootloader officially. I cannot seem to be able to root/flash recovery onto my phone.
I tried the Miui India toolkit - I get an error message: error unhandled exception has occurred in your application blah blah blah Could not find file c:\1.txt
I tried following this guide, and it worked once but it also broke Wifi - wifi refused to turn on
http://xiaomitips.com/guide/root-redmi-note-3-snapdragon/
I'm on Global Stable 7.1.8.0. I've tried the China rom and Global 7.2.3.0 but both roms are much worse on my phone - I no longer get notifications from my messaging apps, Blackplayer keeps stopping and restarting from the very first song it started playing, and other random bugs
Any help would be greatly appreciated, thank you

You unlocked your bootloader on stable ROM? Are you sure? According to this post it doesn't work on stable and it didn't work for me (same model).
Check it in fastboot (power off device and boot by holding Power + Vol Down):
1. Connect your RN3 SD to PC
2. Open cmd.exe and change to your ADB/fastboot folder with "cd <X:\myADBandFASTBOOTfolder\>" (replace with whereever fastboot.exe is located)
3. Check the connection with "fastboot devices". It should show something, meaning that your PC recognizes your device being connected through fastboot.
4. Enter "fastboot oem device-info". The line where it says "Device unlocked:" should be "true". If not, your bootloader is still locked.
Anyway, I suggest going to an official Developer Version (if you are on Global Stable, install Global Dev; China Stable -> China Dev). IMPORTANT: Search through forums, if an OTA update is safe to do, when your bootloader is unlocked. It might (!) lock it again, meaning you have to wait again, since Xiaomi only allows one unlock a month per device.
When you are on Dev ROM with bootloader unlocked, follow this guide to flash TWRP and patch the boot.img (important, so it doesn't replace TWRP with stock recovery again after the next boot). Go into recovery (Power + Vol Up) immediately after flashing TWRP, without rebooting to system. If TWRP is in Chinese, check out my comment here on how to fix it.
After successful installation of TWRP make sure that it's permanent (reboot the device at least twice and enter TWRP again). If that is the case you can search for the latest SuperSU.zip and flash it through TWRP which should give you root.
Hope this helps.

Hello
Sorry to rephrase: I flashed to China Dev rom via MiFlash and unlocked the bootloader offically, however this rom had odd errors and bugs so I went back to the older Global Stable. My understanding is that the bootloader is now unlocked regardless of what ROM i am running?
In the guide you linked, the OP mentione "no patched boot.img required" yet you recommend I patch the boot.img? Can you advise how I should do this?

I think going from China Dev to Global Stable is giving you troubles. Since you already flashed another Official ROM after unlocking the bootloader I don't think it would make matters worse if you did it again now. Try flashing the official Global Dev Qualcom http://en.miui.com/download-301.html and check again if your bootloader is unlocked through the method I posted. After that - if it's still unlocked - you should be able to follow through with the guide.
Right, the boot.img is patched automatically through TWRP when you enter and exit it. Just flash the recovery and confirm overwriting files, so it doesn't go back to stock, when you exit TWRP. You should get a notification when you try to rebbot to system through TWRP.
Just as an update - I was able to flash Cofface's recovery on Global Stable 7.1.8.0 (since my phone refused to update me to any other rom) using the provided guide http://forum.xda-developers.com/redmi-note-3/development/recovery-kenzotwrp-cafface-3-0-0-t3369341

Trouble with flashing official Xiaomi stable ROM on Redmi 3

Hi y'all!
I'm really having trouble flashing an official stable rom on my device. The rom archive is miui_HM3_V7.3.2.0.LHPCNDD_6a5e1bc33c_5.1.zip.
I downloaded it and copied it to a folder (downloaded_rom) on the internal storage of my redmi 3. After selecting it in the updater app I get asked whether it's OK to delete all data, because the rom I'm updating to is older than the one installed. My phone's miui version is MIUI 77. Stable 77.1.1.0 (LHPCNCK). The doble 7s seem odd to me and may be part of my problem (I bought the phone like that). Then, the device is rebooting and I can see some kind of progression bar for a couple of seconds on the botton of the screen but then it just reboots into android and nothing changed
I also tried to flish it via Mi PC suite. Here, after connecting the device in fastboot mode, I got the message that my device isn't supported.
I also believe that the bootloader is locked and I already got the "permission" from xiaomi to unlock it but I had no luck with this either. The Mi unlock tool is telling me, that the "current account is different from the account info on the device" which wasn't the case after I double checked.
Am I missing something here?
kind regards
lunatikk
yes.
because you are currently in modified rom (rom supplier or seller, etc, etc) you cannot update or do anything about it
flash the official rom using miflash method
after that you can update using updater program

I'll try that and report back. Thanks!
Okay, finally I managed to flash my phone with the newest miui.eu rom. What I did was:
- Flashing the official Xiaomi Rom (MiFlash package) via MiFlash (1st try in Win32 wasn't working. 2nd try on Win64 did the job)
- I had to update to the newest official stable OTA, because somehow, I wasn't able to unlock my bootloader with the older version.
- I unlocked the bootloader using the MiFlashUnlocker.
- Updated to the official MIUI 8 dev rom using updater app on my phone
- On dev rom I granted root acces to flashify and flashed the twrp recovery image on my device (which gets wiped from my device every time I reboot - anyone knows why??)
- Reboot into recovery and flash the MIUI.eu zip which is now running on my device.
Thanks for the help guys!
Hi.
I am having the same problem, with pre-installed rom: MIUI 77.1.1.0 Stable. The updater app obviously doesn't work (now i know why) and the MiFlash software doesn't seem to work either. It doesn't recognise the phone, browsing to the downloaded rom does nothing. Am i missing something?
Update, it now recognises the phone, but miflash is saying it can't find the file specified (0x80070002: Execute flash_all.bat)
Thanks for any assistance you can give.
Update 2. Just found out you need a different version of the Rom for fastboot. available from http://en.miui.com/a-234.html for anyone searching.
Okay so Miflash began the process when i had the Fastboot rom, but failed at about 2 percent as the device is locked.
Although i have permission the Mi unlock tool won't unlock my phone as it says the accounts don't match that on the phone, although i have quadruple checked them.
Research suggests it might be a problem with the custom rom on my phone, or that i need to be on the China Dev rom to unlock?
But i can't flash the China Dev Rom!!!
Is there any way to get my device to stock rom?
Sorted.
For the benefit of anyone searching, i followed the instructions here: http://en.miui.com/forum.php?mod=redirect&goto=findpost&ptid=242867&pid=4510751

I just recently went through most of what you have gone through... Be patient though... It seems that the unlocking of bootloader even after you getting permission, takes atleast 2-3 weeks more.
- You can flash the miui global dev rom, you may download it from the miui forums... Here is the link for the fastboot rom http://en.miui.com/a-234.html.
- To flash the dev rom, you need to ensure you put your phone into fastboot, ensure all the fastboot drivers are installed on your computer
- Also, you need to ensure that you download the GLOBAL/DEV FASTBOOT ROM(this is different than the regular zip package) that you download.
- Then you can follow the instructions to install the ROM using miflash tool
- If the ROM installation is a success, then you just need to wait patiently atleast for 15-20 days from the time you got unlock permission sms from MI
- Then try running the flash unlock tool, it should get unlocked.
- Now flashing TWRP might be tricky, I was able to flash the official TWRP, but had issues where the internal memory wasn't getting mounted, because you keep getting asked for decryption password in TWRP to mount the data, no matter what you enter, it might not work
- After trying many TWRP types, the one that worked was "zcx twrp"
- Once you flash that, you should be able to flash any custom or miui roms you need :good:

You may try the steps on this link http://en.miui.com/thread-235865-1-1.html
Skip the EDL thing and go directly to the part where they explain how to use the miflash tool to flash a fastboot ROM
I should have asked this first... what's the state of your phone right now? Does it boot, stuck on boot loop, or are you able to boot into some ROM.
maybe u have a vendors rom, flash the fastboot rom using edl
finally a downloaded adb 1.4.3 and installed it and i flashed dev rom in EDL mode.
but now i have some questions:
can i change kernel with locked bootloader?
if i change kernel does fingerprint work?
You just dont have proper drivers installed im 100% sure, else it would go via edl
Hehe was right������
And why dont you ask for official unlock approval? Its approved in less than a day, anyone saying otherwise have old news
Or you can always use a method in this forum...

Also tell me the best twrp beacuse there are many twrps. I just want to flash aosp stuff and also tell me the best kernel with the most stable latest android n with volte
Thanks i advance☺
Hey there.
1) I think you should try to check and see if you do have an official version of MIUI, not a vendor version.You can check this by seeing if you have ads or things like that popping up in your phone. The reason I say this is because MIUI actually gets updated pretty regularly. If you just don't like MIUI because of update issues, I think you might want to try flashing a known global stable version of MIUI(which is the official MIUI that is supposed to ship on MI devices) before doing anything else.
As for how to flash your device, the steps are below.
1) Unlock your bootloader using the official method from Xiaomi.
you can apply for unlock permissions here http://en.miui.com/unlock/
after applying, you will have to download the MiUnlock program and install it on your computer.
Plug in your phone to your computer to allow the drivers to install.(It's an automatic process)
Check the email account associated with the Mi account you used to apply for unlock permissions every few days.You should receive permission to unlock within the week.
After you have received permission,
Boot your phone into fastboot mode(vol down and power buttons held down at the same time from power off state)
plug your phone into your computer(please note to use the original cable and a stable usb port)
open the MiUnlock program
Click unlock.
You will have successfully unlocked your bootloader at this point.
2)Check your device version by going to settings> about phone.
If it says hexa core processor, refer to the snapdragon forums
If it says octa core processors, refer to the mediatek(mtk) forums
3)Flash an official Xiaomi ROM for the appropriate version of your device.
you can follow this extremely detailed tutorial here(please note that everything from this point forth will be a tutorial for the snapdragon version and should not be used on the mediatek version)
http://en.miui.com/thread-235865-1-1.html
4) If you are still unsatisfied with the Official MIUI, you can then proceed to flash a custom ROM of your choice.
Flash TWRP.
After that, flash Alka recovery.
You can compare the different versions of TWRP available here http://forum.xda-developers.com/redmi-note-3/how-to/guide-redmi-note-3-available-twrps-t3406708
For this part, you can follow the tutorial made by rootjunky.com on youtube.
After that, backup all partitions of your device onto your sd card.
Flash the appropriate firmware for your Custom ROM
Flash your chosen ROM
Flash Gapps.
Done.
A good ROM to start out with would be CM13 by TheStrix.
A good kernel would be Radon Kernel.
Personally, I wouldn't use CM14 yet as it is not completely stable.

rollback to global beta 10.9.6.24

hi everyone am on the last global stables 10.3.6 am facing battery drain and slow battery charging.
i want to rollback to the beta 10.9.6.24 everything is perfect there.
can you plz explain me how to do step by step .
do i need to unlock the bootloader ? use mi flash tool ? and falsh fastboot 10.9.6.24 ( where can i downloaded it )?
any help is welcome
There are 3 ways for rolling back:
1. download recovery rom and simply flash it via twrp ( which is the most common) but since you have locked BL and therfore no TWRP you can't use this method.
2. download fastboot rom and flash it via miflashtool (by putting fone in fastboot mode) this is the best method for you and one that works with locked BL. Also make sure that you are flashing the FASTBOOT version of the rom. Since there are 2 versions for each Rom. Recovery rom and fast boot rom. And as mentioned earlier, you will need fast boot rom for this method.
3. EDL method but you will never use that, it involves putting phone in EDL mode (back panel is remove and two short points are touched via wire on motherboard and usb cable is plugged in and then fastboot rom is FLASHED by miflash tool, this is usually done on BRICKED Xiaomi phones and MIFLASH asks for AUTHORISED ACCOUNT, which atm are only found in their official service centers.

alright i Will go for the second method .
do you know where i can find fastboot 10.9.6.24 rom I've searched but didn't find that one i found only the latest beta which haven't been as good as 9.6.24

We never had a version 10.9.6.24. U can only go for 9.6.24 (beta rom) or 10.x.x.x (stable rom).

This link below contains all MIUI roms that have ever been released to this date.
https://xiaomifirmware.com/roms/official-roms-for-xiaomi-pocophone-f1/
Also as someone else mentioned, there has never been a rom such as the one you stated. The latest global stable rom is 10.3.x.x and will probably take years to reach 10.9.x.x. You must be confusing it with beta roms that usually start with 9.x.x.x serial.
And as you will be going from stable to beta, make sure you backup EVERYTHING or you will loose it.
Going from stable to beta, or vice versa, wipes the phone of all data...
You have been warned...
