Hi, i have troubles with rooting my phone.

Basically, the "fastboot flashing unlock" or "fastboot flashing unlock_critical" commands doesn't work, the output is :

PS C:\Users\agentflemme\Desktop\tel\platform-tools_r29.0.5-windows\platform-tools> fastboot flashing unlock_critical

...

FAILED (remote: Unrecognized command flashing unlock_critical)

finished. total time: 0.009s

PS: I'm using fastbootd as the fastboot doesn't work on the phone because it is just not recognized by the computer, even if i install the mt6771 or latest MTK usb drivers.

I have tried many other methods like adb sideload or just an oem get_unlock_data (which gets this error : FAILED (remote: Command not supported in default implementation) ) but nothing got rid of the security.

If someone has any information on this problem, please tell me.

I can provide all hardware or software information, such as the serial number or the version of the bootloader ( if i trust fastbootd, it is "unknown")

I have also kept the box of the phone, if necessary.
[Android Q&A, Help & Troubleshooting] DragonPitbull:
You cannot unlock command in the fastbootd! You should use bootloader - fastboot to do.

Try updating drivers and platform tools - adb-fastboot to more details. Obviusly if you not make the Settings - about phone - tap 7 time the build number - developer option - select OEM Unlock - USB Debugging...... So the process never happening.

thanks for the reply

i used my linux distro and i was finally able to detect my phone in fastboot ! yay

i think after i successfully root my phone ill seek for some custom roms

if you have some good ones, and stable (i dont know if the android roms are adaptative or built just for one device), lemme know !

Hi bro, I just want to ask, does step 00 until to step 16 are all I needed?

I just want to get my power3 to be rooted. I want to recover my files after a factory reset because after 2 years of using this device it decides to fvck up (see attached) and leaving me no choice but to reset it and lost all my data/important files.

PS. I extensively researched how am I supposed to get back my files after a factory reset and the only workaround for these softwares is to get your phone to be rooted to do deep scanned recovery.

PSS. Before I got to the decision that I must factory reset the device. I did all I can, like flashing updates. But nada.

I recently purchased an Umidigi Power 3 from ebay. I heard that the latest update ruins the sound and that some models face corruption issues preventing them from booting. I haven't received my phone yet. Will flashing a gsi rom allow me to avoid these problems?
[Android Q&A, Help & Troubleshooting] Tatsun0x0:
Okay, so I've finally got the tools to be able to retry porting TWRP for this phone. So far I got myself up to the point that I was able to finalize the twrp.fstab and was able to pull the recovery.fstab of the MTK device. @Augustoandro I followed your TWRP porting guide to the best of my ability and ended up with the ff. not bootable image for the Umidigi Power 3. Something tells me that despite using the android kitchen to repack the image, it still wouldn't be enough to boot into TWRP recovery.

[Android Q&A, Help & Troubleshooting] noobJr:
I don't know if it is the same problem i have, my phone is a Umidigi F2 and the command "fastboot -w" only worked when i was first in the fastbootd menu, in this menu my Windows not even recognize the connection it was necessary to use a Linux.

The command to delete and to resize partitions didn't work I'm assuming the command "fastboot reboot fastboot" goes to fastbootd menu but i only managed go there manually with the buttons, go to recovery mode them select the option Enter fastboot.

The only commands recognized were

"fastboot -w"

"fastboot erase system"

"fastboot --disable-verity --disable-verification flash system system.img"

In the case to resize or delete partitions there is the lpmake and lpunpack.

Extract super.img delete product.img put a bunch of thrash in system.img until i get 3Gb don't touch vendor.img, remake super.img only with system.img of 3Gb and vendor.img and send it back. This was the method i used to delete/resize partitions, now in fastbootd i used the commands who worked and flashed the lineage.img in system. To my surprise this worked.

Hi,

My experience in case can be useful for someone, I just wanted to root so I stopped in step 12.

Following steps in page 1 bricked my phone, maybe due to passed time or something else.

Link for stock Rom seems incorrect, scattered file correspond to another processor. The one that worked for me I downloaded from xdafirmware.com

Umidigi Power Stock Firmware ROM (Flash File)

Download Umidigi Power Firmware ROM (Flash File) without any password for Free. We also provide the Flash File for other Umidigi devices.

xdafirmware.com

Patched magisk boot didn't work for me neither, I patched boot myself by magisk.

And finally vbmeta_vendor and vbmeta_system don't exist in my phone, so I replaced with system and vendor.

After that root was succes.

Thx.

Hello guys!

Does anyone have a "persist.img" file from the Umidigi Power 3? I flashed the Android 13 GSI and everything worked fine, but somehow the fingerprint sensor doesn't show up in the Settings of the phone. So i want to flash an original working copy of a "persist.img" file to see if that fixes the problem. I don't want to get back to the stock rom since it never was a good rom. Can you please help me extracting that file from your phone so I can try with it?

Thanks in advance! You will save my life.
[Android Q&A, Help & Troubleshooting] Hobler:
Has the fingerprint ever worked with the GSI rom? I have the same setup as you (Android 13 GSI) and have tried many other roms and the fingerprint always worked. Which GSI rom are you using? I'm using the latest GSI Android 13 from ponces...

I've never had anything to do with the persist.img. Is this file included in the firmware or do I have to extract it from the phone? Maybe I can help you with that :-)
[Android Q&A, Help & Troubleshooting] EraserNeo:
I'm using the Android 13 GSI for the Pixel phones, the pure one from the Android ROMs page. I don't know why the fingerprint setting doesn't show up in the Settings of my phone after that, maybe I did something wrong when I was flashing it. I've read that many people has had that problem on other brands like Xiaomi or HTC, and the solution they suggest is to flash that "persist.img" file. It seems to be a file that contains information about the phone sensors, chip data, calibration, etc. Unfortunately that file is not exposed in the zip file of any ROM, but it can be extracted from the phone itself by ADB, using TWRP or a terminal app with this command:

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

Take a look at this thread where there is more information about it: https://xdaforums.com/t/extracting-stock-boot-recovery-and-persist-images.4058447/
[Android Q&A, Help & Troubleshooting] Hobler:
I'm very sorry, but unfortunately the command doesn't work :( What I can recommend is that you install a rom WITH TrebleDroid patches. These patches make many things possible that do not work with pure AOSP. Probably fingerprint too... I would really like to help you, the Power 3 is a great phone with GSI <3 .

Power_3:/ $ su
Power_3:/ # dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
dd: /dev/block/bootdevice/by-name/persist: No such file or directory
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000127 s, 0 B/s
[Android Q&A, Help & Troubleshooting] EraserNeo:
Interesting, there's no "persist" file at all inside the Umidigi 😮 Thanks a lot for your help man! I will definitely try a different rom with TrebleDroid patches, maybe the same one from ponces that you already tried and works fine.
[Android Q&A, Help & Troubleshooting] EraserNeo:
@Hobler I want to thank you again for your suggestion. Yesterday I installed the AOSP 13.0 v2023.09.19 from ponces and my fingerprint sensor is working again! :)

Now that we have the exact same setup, I wanted to ask you a question. Is it a way to safely root this phone having this GSI? When I try to use TWRP to flash the phh's superuser zip, I'm not able to see the contents of the sdcard because everything is encrypted. I see a lot of folders with dummy names. So I can't flash anything. This makes the TWRP completely unusable. Have you had this issue?
[Android Q&A, Help & Troubleshooting] Hobler:
Yes, TWRP is unfortunately unusable on this phone :-( Even if the phone is rooted, some folders are read-only. Magisk, for example, can only be updated via Fastboot.

And that's exactly how you have to root the phone: via Fastboot! The instructions on page 1 in this thread are great, that's what I did back then 2020.

Since you have TWRP installed, you probably already unlocked the bootloader?! So patch the original boot.ini with Magisk, then flash it via fastboot. Then your personal data won't even be lost ;-)

Do you actually use Android 13 from ponces with Gapps or without? If without, Android 14 would even run! Unfortunately, with Gapps, Android 14 is too big (over 3.5gb) :( That's too big for the phone.
[Android Q&A, Help & Troubleshooting] EraserNeo:
The truth is I'm afraid of Magisk in this phone 😂 I read the instructions on the page 1 but they say that installing Magisk in a GSI will result in a bootloop. That's why I didn't try it at all. I remember that in the past I was using the Stock ROM and I was able to root with Magisk. But after some time, weird things started to happen. The apps that I had installed in the phone stopped working one by one, day by day. Photos and other files started to disappear. Until one day the phone became unusable. I had to flash the stock ROM again without rooting and everything fixed. I don't know what happened at that time.

I'm using Android 13 from ponces with Gapps. But that's good to know! In the future when I want to try Android 14 I will definitely flash it without the Gapps. Thanks!!
[Android Q&A, Help & Troubleshooting] Hobler:
Oh, that doesn't sound good at all :D I've been using Magisk since day 1 and I've never had any problems with it.

I've been using GSI on my phone for about a year now and only with the Magisk patched boot.img. I've never had bootloops because of the Magisk-Patched-boot.img.

So I can only recommend you to install Magisk :-)
[Android Q&A, Help & Troubleshooting] EraserNeo:
Did you use the same magisk patched boot image that is attached to the first post of this thread? Or did you patch the boot image yourself using a specific version of magisk?
[Android Q&A, Help & Troubleshooting] Hobler:
No, I prefer to patch the boot.img myself, it's a bit safer for me ;-) The attached file probably only supports a very old version of Magisk.

But you don't need a special version, there is no difference between Stock rom and GSI :-)

PS: I'm very happy that I'm not the only one who appreciates the phone so much! :-)

Go to settings and then tap on "apps and notifications" (may be labeled differently on android 10). After that tap on "notifications" then on "on lockscreen notifications" and make sure it's set to "show all notification content" that should fix your issue.

Power 3

Unlikely. UMIDIGI doesn't have the fanbase for that level of development. Mediatek doesn't release its code either.

I lucked out by getting an unit that doesn't have too many issues. But I see a lot of people struggling with audio. Wouldn't recommend this phone. If you still want to buy it, go through Amazon. So, you can return it without a hassle. It does bump up the price though.

[Android Q&A, Help & Troubleshooting] mrmazak:
Yes three attempts to fix, one even says specific it is a fix for speaker, but the update is flagged as rejected. And advised not to flash it.

Multiple possible "work-around" fixes.

1. Disable ok Google

2. Enable "click" sound on button push

3. Use gsi rom.

From what I was reading, and hearing the issue is a bad equalizer app.

Making the click sound forces the eq to never sleep.

I Don't understand the ok Google work-around,

GSI rom has its own eq and bypass the issue.

.

.

Few more found suggestions ,

Plug headphones in and out few times.

Makeing a phone call, is also a fix that said to reset the EQ.

I just hope for a firmware update fix though.

Yea I just shut off google voice "listen all the damn time to you spying" service. ;)

But anyway...I know it's always a "risk" buying a china phone...I LOVE THIS PHONE AND DON"T CARE! lol. I'm routing all my data to the russians via adguard anyway so all good haha.

What is really weird it that Umidigi decided to create their own AOSP dialer/contact app. It's not googles official app. What tipped me off was that it doesn't go dark in dark mode. I looked up it's open source licensing it lists...it's a legit thing but I just wonder why? and the fact that it stays white in full system darkmode bugs my ocd! lol FYI: you cannot install the latest version of Google's Dialer app from apk mirror; it's not even in the play store BUT you can the official Google Contacts app from the Play Store OR apkmirror. Just odd to me.

Anyway...100% love this big ass buggy beast of a phone. But I've been rooting since 2008 so yeah...I love this type of stuff. Hell if Xiaomi and Redme and Realmi and Poco, and Oppo, and all the rest supported true global lte bands..? I'd own em all. I DETEST that in the US it's either Samsung or Apple for the top dogs! they make boring ****.

Keep the thread going would love to have a decent sized owners thread here on XDA for folks!

BOTTOM LINE FOR NEW FOLKS READING THIS: This phone, the Umidigi Power 3 is LEGIT! No evidence of spyware, nor evidence of tampering with specs to make it look better than they say it should be! I've used many app from XDA here to test things and get true specs. L-E-G-I-T!
