[Moto Z2 Play  Questions & Answers] varun.katoch:
A possible reason for losing signal is that the rom provided on XDA was not for your region.

IMEI can be restored if you have your EFS backup in TWRP.

However, I guess you will only get the signal once the latest PIE (9.0) is released for your region/software channel.

P.S I am also stuck on no signal/can't turn radio on since I upgraded with PIE rom of US/BR region. Downgrading to OREO didn't help either because I was not able to downgrade the bootloader.

[Razer Phone Questions & Answers] duckhei:
Hi All

My fd update his phone to Android 9 yesterday(do it on the phone, not the computer)

When the phone is completed and restarted, it stuck in the screen logo razer and the message " download mode " in the upper part .

He tried to restart the phone, but the same problem kept happening

Then I tried to press the power button and volume "+" at the same time to enter recovery mode, but failed, it went into the download mode again..

I have tried the command " adb reboot recovery " and I have the message " error : no devices/ emulation found

Then i tried the command " fastboot reboot recovery ", it went into the download mode.

Then I tried to flash the factory images.

Sadly, he did not unlock the bootloader and did not enable USB debugging...

So i can't flash the factory images....

When I execute the flash_all script...

It show FAILED ( remote: Flashing is not allowed in Lock State

)

Is there any other way to rescue it?
[Nokia 3.2 Questions & Answers] HansiHusten:
I buy for our company only Nokia devices as Android One is for me the single most important feature! The devices are cheap and overall ok. Everything was smooth, until now.

We used Nokia 3.1 in the past until now as they ran out of production and they get kinda old, so I bought now the first 3.2 devices and I noticed, that the newest security update is only April 2019!

I tried multiple ways to force and update, which didn't work, and even had an hour long chat with the support telling me that for this build 00EEA_1_03D is really the latest update April 2019 and he cannot help me at all.

How can this be as Android One should always have the latest version of security updates?

We bought the devices on amazon.de where someone else also stated that he was stuck on April 2019.

So does anyelse have issues or experience with stuck or non-monthly-updates for the 3.2?

I used in the past -quite some time ago- FunkyHuawei to update my Mate 10 Pro. Ok I did not use the phone for a while and just found it somewere in a drawer, recognizing that it is still on security patch Sept 2018. Reading that even this old phone might get Android 10 I was trying to update it via the sytem updater. This methode failed. It cannot find any update, the same with eRecovery and HiSuit....as I do not have any credits left on FH I am looking for a way to force updates to get it updated. The device has a locked Bootloader and I do not have any unlock code.

BTW, does anybody know, if FunkyHuawei adjust its Rom's in a way that is preventing the phone from getting the official OTA updates?

Hi to all, I wrote here after trying everything from a long time. I explain better :

Sometimes, randomly, my phone mess up with the various application and give me some heavy lag and freeze, he remove some of my personal data (sometimes whatsapp files, sometimes other files, randomly) after that it stuck with a black screen or some similar and if I try to restart he stuck at the boot logo. The first time that this happened I spent a lot of time for understand what was to do this problem and after some trying I noted that this problem coincided with an error in twrp about the "persist partition" (something like unable to mount or read persist partition). So searching around the various forum I understand that I have to flash a "partition.img" for resolve the problem and that is what I do. It apparently solved the problem but my phone continue randomly to make this problem, It seems that the more time passes, the more often it will do this problem. I read that can be a memory chip problem and than the only solution is to send to the assistance and make them to resolve this. Someone of you have the same problem ? And how you managed to solve this ?

your problem is similar to k20 pro problem that i had as well as so many other users.

looks like you did install FDE through magisk and it messed up your phone perminently

we've been trying to figure out a fix for the lag and freeze and wiping of the memory but its been almost 3 months without any fix.

so most likely it is unfixable

don't try to mess up anything and just send your phone to service center they will replace the motherboard . its the only available fix at the moment

[Xiaomi Mi 8 Guides, News, & Discussion] tsongming:
Persist Issue Solution

It's not unfixable, it can be resolved by at least 4 different methods.

I have explained how to permanently resolve this issue with extensive instructions on at least 20 to 30 threads. Including the one above. And here: https://xdaforums.com/showpost.php?p=79824537&postcount=2

As you can see, wasted time with no thanks given.

This issue is cause by encryption, that all there is no damage whatsoever. If you saved a Twrp backup the issue can be resolved in 2 seconds by restoring persist images.

It can also be resolved by flashing persist images from a dipper images rom, then immediately signing into your MiCloud account or by flashing a fastboot rom with XiaoMiFlash ( making sure to unclick relock bootloader) then boot and sign into MiCloud.

Another way is download all the required Dipper images Rom here :

Fastboot Rom Link : dipper_global_images_9.6.27_20190627.0000.00_9.0_global_30e0fc22ef.tgz

Filesize 2.43G

Download and unpack rom from the link above , as I mentioned on the link above, unpack twice to the desktop, ( the first time decompresses into a larger rom that also needs unpacking)

Open extracted images folder and look for “persist.img” file (it should be located in “Image” folder , see my attached screen, I keep these ready if ever needed).

Copy “persist.img” file to “/sdcard/persist.img”.

Boot into TWRP, go to Advanced/Terminal

In the terminal type the following command to convert the .img file from “sparse” to “raw” format.

simg2img /sdcard/persist.img /sdcard/persist_EXT4.img

After it’s completed, type the following command in the terminal:

dd if=/sdcard/persist_EXT4.img of=/dev/block/bootdevice/by-name/persist

After the flashing is completed, you can reboot into the system and start using your phone.

The next method is posted above, its an older method that uses the Kitchen app

Ideally you want the base firmware to be the same as the rom. but its not absolutely necessary, once you have flashed the persist image, immediately install a Miui Rom and sign into your account, once you are on the main desktop, reboot to Twrp and make a full backup, then copy it to your PC.

Make sure that the backup includes the persist images, modem, efs etc. As I said a full backup.

This backup will give you the peace of mind knowing, that you will never need to repeat the steps above again.

Other times the solution is the adb fix, which usually always works.

I just mentioned this to someone else, do not flash someone else's persist backup, that will work temporarily and then makes matter's much worse.

On the Mi8 there are only a few versions of Twrp that will allow you to backup and restore that persist image alone. If Orange Fox is available on your device try using it. See attached image

Edit one last thing

If attempting to use the persist image extraction reflash method, the image must come from a fastboot "images' rom

Did you have this problem before using Xiaomi EU rom? I am on stock rom and planning to go to EU. But a lot of users in EU forum are also facing persist problem. I am using Mi 8 for almost 1 year with Global Beta/Stable rom. Nevar faced this issue.

Maybe it's caused by TWRP or EU rom?
[Xiaomi Mi 8 Guides, News, & Discussion] tsongming:
It's not caused by the EU rom, the EU rom is really nothing more than official Beta Miui ( Chinese version, which is 3 to 4 months ahead of the Global version) So beta Miui with Google services added and useless bloatware and ads removed.

There have been many cases of people experiencing these issues on AOSP roms as well. For example, the many reports of WIFI, Data, Cellular Services, BT not working etc.

The issue is a permissions conflict, that is mostly likely caused by continuous flashing of Root and Dm-Verity. Albeit incorrectly.

If you have Twrp and no root then flash Dm-Verity. If you plan on using Root then don't use DM-Verity, it's not needed.

When I stopped flashing DM-Verity is when I stopped experiencing issues. But as I mentioned if you don't want root ,and you definitely want TWRP then you must flash DM-Verity otherwise TWRP will be overwritten when using a stock based rom.

Do you know why my /data partition gets broken too when this /persist mess up from magisk happens?
[Xiaomi Mi 8 Guides, News, & Discussion] tsongming:
I believe that I do.

I choose to not encrypt my phone. However, certain roms, especially experimental may encrypt your data anyway. Back in early August I kept having bootloops and persist issues.

I stopped having issues when I went back to the flashing steps that I used with my previous phone. ( Rarely if ever using Dm_verity)

Edit: Comment below concerns Stock based Rom

Dm-Verity is needed if you want to use a custom recovery such TWRP, and you do not want or need Root.

If you are planning to root the device, then do not flash Dm-Verity. Magisk already has a function which takes care of Dm-Verity and Encryption. So there is no need to flash Dm-Verity.

The problem is that too many people think that Dm-verity is needed, along with Magisk and with every update, it's not unless you are not rooted and in most cases if you are rooted Magisk will check the the boot to ensure that it is still rooted. So flashing Magisk is not always needed ethier. As an extra precaution, I remove all passwords, pattern looks, and face unlocks prior to updating a Rom. I plan to make a post about Dm-Verity soon but will not have time to get to it until Monday or Tuesday.

I hope this helps.
[Xiaomi Mi 8 Guides, News, & Discussion] alone_in_dark:
I want TWRP only (no root). So, Do I've to flash DM-Verity each time I update rom? Will flashing DM-Verity cause problem? And can you please share your steps of flashing ROM?

Thanks
[Xiaomi Mi 8 Guides, News, & Discussion] tsongming:
If you are not flashing root, that is when you flash dm-verity, and it must be flashed before flashing the ROM.

Another option is to use the latest Orange Fox TWRP which has dm-verity built in, I use Orange Fox.

As I mentioned I remove passwords prior to updating. Boot into TWRP, select wipe, swipe factory reset, flash either dm verity or root but not both. ( I do not user Dm-verity, I use root) Flash ROM, that's it.

Orange Fox is laid out very differently than TWRP but it's very much worth using, explore every option, lots of nice functions built into Orange Fox, including dm-verity and root. DarthJabba provides great support on that thread.

[MENTION=4877295]alone_in_dark[/MENTION]

Edit: One last addition: This from the Orange Fox Q& A Section

Do I need to flash a "DM-Verity / Forced-Encryption" zip when using OrangeFox?

No.

Thank you so much
[Xiaomi Mi 8 Guides, News, & Discussion] tsongming:
[MENTION=4877295]alone_in_dark[/MENTION]

I am not sure if you saw my edit, and now thinking about it further I definitely wasn't clear.

If using these versions of Twrp, DM verity is not needed at all. :

Xiaomi.EU version: https://www.androidfilehost.com/?w=files&flid=50678

Orange Fox : https://sourceforge.net/projects/orangefox/files/latest/download

Dm_ verity is mostly only relevant when flashing stock or a stock based rom. One more thing, I talk to so many people on here that it sometimes bleeds together and I did not know/forgot that You are coming from Stock.

Usually, you will need to wipe your user data, when moving from stock to another rom.

Backup your Data to your desktop, If you get a bootloop after installing Xiaomi.EU , you will need to remove encryption from your SDcard/Userdata by selecting format, type yes, reboot to recovery.

Depending on how you have setup you mi-Cloud and google restore , much of your data and setup will be restored.

Personally I copy my local backup over to the desktop and then restore it after creating the Miui folder by running a test backup of settings.

I switched to TWRP-3.3.1-0607-XIAOMI8-CN-wzsx150 and the OrangeFox. both versions have built in functions for DM-verity/Opt encrypt and encryption removal. In my case when the the issue was not immediately, resolved TWRP would stop working as well. Sometimes, I could regain access to the system by flashing the boot image.

[Xiaomi Mi 8 Guides, News, & Discussion] tsongming:
I dont think its related to the OS or EXposed/EdXposed in general although they could play a role, maybe along with TWRP and Magisk It more or less seems to be a encryption problem. so who can say for sure.

Regardless, I have made a full TWRP for everyone in my family that has a Xiaomi device. One thing is absolutely certain, in a worst scenario if you have an unfixable Persist issue, restoring the persist partition from your own personal TWRP backup works every single time.

I recently just updated my dads Mi8 to the latest Stable Miui 11 Global rom and his phone, ran horribly and had its first serious issue. Unfortunately, I did not update TWRP and I am sure that it caused the issue. He was using the phone and it suddenly shut down, would not reboot, and would not boot to TWRP.

I ended up having to completely restore the phone to stock, then flashed TWRP, Root, formatted the drive and installed the latest Xiaomi.EU along with Magisk and Orange Fox 10.4 and now its fine.

@ NightScap3

Just to let you know, I just had a persist failure once again, and this time noticed that my phone signal was dropping or actually the ico was completely missing and even after restoring the phone the Mi Verification failed and also a service called com.Xiaomi.anti fake.

it turns out that there is an installable service that Xiaomi typically uses to verify the IMEI number, Sim card and the phone ID, I guess in China there are a lot of Xiaomi fake phones?

The Mi Verification tool is not yet working on Android 10, but you can force the check by going to all specs and clicking on internal storage 7 times, this will bring up the phone info menu, I scrolled down to refresh, and triggered carrier provisioning and the then Mi verification worked.

This is probably what cause the persist issue, its a bug. Also, the persist is missing or damaged message is clearly wrong, its encryption, If Xiaomi does not verify the device they shut it down...its a guess and I can't prove it. But I think this is the problem. But only for some of us?, My sim card is several years old, I plan to get a new sim card and see if that is possibly causing my issue.

I can tell you, that I had the issue on AOSP already on Android 9 and also on Android 10. If you thing it's the Anti Fake Application, why do AOSP Roms have these problems too
