It's almost impossible to hard brick a Mediatek phone unless you can't reboot or power off. SP flash tools is a must for us.

Is your default USB set to file transfer?
[Android General] MeepMan:

[Android General] MeepMan:
I will locate stock firmware on the web, since UMIDIGI forum post doesn't seem to work for me. Mirror links appreciated but I'll find it eventually. I'm looking for the latest 0826

aha I can give you +15 social credit this is truly a reputation moment
[Android General] dcn61:
Not sure why you are not getting adb authorization but maybe you could re flash stock and start again. Usually revoking permission works for me. In the past I have had a torrid time of it on Windows but no problem on Linux.

HUh download is working idk why it wasn't before but thanks very much!!

now I only need to be sus while I wait for the 1 hour download
[Android General] dcn61:
No worries!
[Android General] MeepMan:
So, to be honest I do not know what is going on. I have downloaded SPFT (5.1916 as was recommended in one of the original posts) and the stock firmware 0826 for my global phone. The first thing that I wanted to do was to backup the nvram in case something went wacky but when I plugged the phone in it got stuck at 0% (after almost instantly completing the red "download DA" bar). I tried a couple more times and the best I was able to get was 3%, perhaps because I had not waited as long as I usually do after powering off the phone to plug it in but unlikely. Trying again resulted in 0% afterwards. I will soon check the file for corruption as soon as I am able to read it (since I'm on Windows currently) and, no, Illuminati, you can't have it.

Anyways I went to flash the stock firmware guessing that the nvram would probably be fine, but once again it was stuck at 0%. I have tried pressing volume buttons but it hasn't helped. I won't be trying to flash again until this issue is resolved because if it gets stuck at 3% again that's gonna be a painful (soft?)brick.

Based on the unauthorization, fastboot denial, and now the SPFT failures, my working theory is that there is something corrupted, damaged, or infected with my firmware (maybe hardware but I doubt it, I try to keep my things nice) that does not allow/permit for certain interactions through USB, unless the device is powered on?? SPFT didn't work with the device on either but I assume this is normal behavior. Perhaps there is a pin or microcontroller transistor that selectively has an existential crisis only when the OS isn't booted; I have no clue. Seems that this problem is exotic and thus, unless a team of professionals is willing to dissect my phone, likely unfixable. Any ideas are welcome but I have tried everything at this point that I can think of :/

UPDATE: I used a linux reader tool to view the nvram file and it looks corrupted as hecc. The beginning has some readable text on the right but when I scroll down there are a lot of blank areas and areas with random-looking gibberish. That said I have no clue what I'm doing (why are the characters grouped into twos and then rows, and what does the text on the right even mean?) and maybe that's just normal ''\..'~'../''. I know that corruption is what one would assume of a file that only gets 3% uploaded but my noob side suggested to me that "maybe the partition is only 3% full.."
[Android General] MeepMan:
Well, I tried factory resetting and also OTA update buut... nothing changed. I guess I'll be living with the stock firmware for now..

The reason I wanted to flash custom ROMs was to disable GAPPs and install some fancy firewalls to make sure UMIDIGI isn't sending my info to baidu or some other crap. I saw that there are some apps that claim to gain root privilege like kingo root, iroot, vroot, towelroot, etc.. do you know if these are legit and safe, and if any of them would work on this device? If so, I would be a little bit concerned about what exploit it's using, but it would nonetheless be very valuable as I cannot (currently) flash rooted partitions with fastboot for magisk. Thanks :)
[Android General] MeepMan:
One thing that I noticed was that after factory resetting, the phone now asks me to enter the password before booting to android at all, which should increase security by restricting /system access completely if implemented correctly (my vague understanding of android boot process)... I am confused as to why this never occured before, and why it decided to do this now, with no option in the settings to enable/disable this "secure boot" as it is often called??? Has anyone else experienced this?
[Android General] VITHOR3E:
Glad to hear it worked for you!

Just got this phone today and so far, I love it. Only gripe is the volume on calls and system volume in general. Does anyone have a tweak for this to make it better?
[Android General] SeekerofLight.iz:
I noticed this too, and Viper4Android can actually fix this too (I'm a huge fan of this mod if you couldn't already tell from all my previous posts about it lol). If you install it and max out the "Playback Gain" under "Speaker" it seems to affect both the regular phone speaker and the earpiece at the top of the phone too. It's not a night and day difference on the earpiece, but it's definitely louder than before. The bottom speaker gets considerably louder though, and you can adjust the bass/EQ to make it a bit thicker and less 'tinny'. The only downside to enabling the Playback Gain boost is that when you pause and play something (like a YouTube video for instance) it takes a short second or two to fade in to full loudness.

If you don't want to install Viper you can try out toggling "BesLoudness" under Settings >> Sounds >> Advanced >> Sound Enhancements. Although this seems to only affect the bottom speaker and not the earpiece or calls.

I haven't encountered that error... I hope you were able to sort it out by now, but if not would you be able to elaborate?

For instance, do you get that message as it boots up on the UMIDIGI logo screen or somewhere else? Did you try reflashing again with SP Flash Tool to make sure everything went through properly?

Do you try this website if it help?

https://unofficialtwrp.com/unofficial-twrp-3-3-1-root-umidigi-power/

I am still waiting for my phone....
[Android General] venso:
No, this TWRP is made for version 1.3 and after the firmware puts the phone into a cyclic reboot. It is not finalized until the end.

Nobody wants to do TWRP for this phone - because the phone owners are very passive people. They do not want to write and discuss - they are able to wait for someone to make READY TWRP,
[Android General] venso:
orange status

After receiving Ruth - you received an incorrect bootloader with a delay in loading and with an orange status.

It is very easy to fix, you only need to flash one file via Flash Tools: lk.img

These are new files and they are the same - I just indicate that this is for version 1.5

And the bootloader error will disappear and the 5 sec bootloader delay will disappear

I laid it out and 72 people downloaded it - Nobody said thank you, nobody wrote a single line in response. I will have a working TWRP the other day - I ordered it from a competent person who is professionally involved in TWRP. And I ask again - is this TWRP only for me?
[Android General] venso:
It is a pity that on version 1.5 of UMIDIGI POWER no one wants or cannot do TWRP. I asked everywhere - and they are silent everywhere - there is no answer. Only one person promised me to do TWRP.

Only I need this TWRP? Then it’s clear that no one will create TWRP for one person. When one of the owners of the phone crashes the system - then you will search for recovery because you have not previously backed up the system and data, you have not saved IMEI ..... Anyway, this time will come .. After all, this is a regular phone.
[Android General] venso:
TWRP for the UMIDIGI Power

Finally I got TWRP for version 1.5

I checked it - it works fine - makes backup and restores all my partitions. I am very satisfied!

Now I can experiment with firmware and applications - I can always roll back to normally working firmware.

Read the preliminary page above this post. After that, I will not upload ready-made working files for this phone model. After all, nobody needs it
[Android General] KimLe:
Can you give the link to download it? Thanks

So. I will never bother you again.:laugh:
[Android General] SeekerofLight.iz:
Sorry, I'm a bit confused. Are you saying you've found a working version of TWRP for the UMIDIGI Power, but you're refusing to share it because no one helped you with finding a working version of TWRP recovery? I don't mean to sound rude, but this sounds like some backwards thinking.

If you did happen to come across a solution it would be much appreciated if you shared it, if you did not find a solution and are just frustrated with the lack of activity here, that's fine. But this isn't a very popular phone, we can't expect to see a lot of support or activity around it in general.

---------- All you think is your problem. Nobody owes anything to anyone here - it's the Internet --------------------

I ordered TWRP and they collected it for me personally for me with my initials in the header TWRP - I financed it. On what basis should I upload it to the network? If you need it, you can get TWRP for free through the Order Table on the page : https://4pda.ru/forum/index.php?showtopic=789936 . Download the stock BOOT, RECOVERY AND SCATTER FILE FROM OFF Firmware 1.5 - After a while you will receive TWRP for free

I already posted a link to version 1.3 for this phone model https://4pda.ru/forum/index.php?s=&showtopic=947978&view=findpost&p=87864709 - it is working. You can ask this developer to collect TWRP for version 1.5 - He will collect it for you completely free within an hour.
[Android General] SeekerofLight.iz:
Oh, sorry. I was a little confused by your messages, and I wasn't aware of the development going on over on the site you linked. These links help a lot. Thank you very much.
[Android General] SeekerofLight.iz:
A big thanks to venso - I was able to find the necessary resources to install TWRP 3.3.1 for version 1.5 as well. I hadn't even heard of that forum site until now. Also, credit goes to user nemo-nemo and Chela_vek over on the 4PDA forums for providing the files necessary. I will go ahead and write up a step-by-step guide in English within this thread as soon as I get some free time this weekend.
[Android General] venso:
I am very happy for you! On this site 4pda - very competent and kind people - they will always help and on this site there is almost everything for any gadgets and applications with ready-made keys. You will need to register on the site and you can download all the files. Just in a search engine for example Yandex.ru - enter the name of the application or phone and add the word 4pda. Google will not find - Yandex - will find everything
[Android General] Paulicat:
Any chance you'll post the 1.5 twrp for this device?
[Android General] venso:
Anyways, sorry for such a long guide. I wanted to be clear and thorough. Hope this helps some of my fellow UMIDIGI Power owners out there! And thanks to the people at the 4PDA forums for providing these files to the community.

Thank you for posting such a detailed description for the TWRP and the TWRP itself.

I specifically demolished my TWRP and flashed the phone from scratch. I wrote down your TWRP and did everything according to your instructions ---- That's interesting -I received only one error while formatting the internal memory - nvdata - cannot be formatted - but otherwise everything went smoothly. IMEI did not disappear and the SIM card worked after flashing the new TWRP. No delays when turning on and rebooting the device - everything went smoothly. Your TWRP was built very well. I sent my TWRP for revision - there is something to fix
[Android General] utz:
Hello,

as i have no windows available, is there a chance to flash by just using adb tools on linux a machine?

cheers

Utz
[Android General] SeekerofLight.iz:
I'm glad to hear it worked smoothly for you! I too received that error but it caused no issues on my end as well. A part of me wonders if it could be related to the fact that this phone has two SIM slots as opposed to one or something? But that's just speculation; either way everything seems fine regardless.

I'm 99% sure it'd probably be possible with a Linux machine but you'll need to find a way to install the drivers and SP Flash Tool. I don't use or have a Linux machine though, so I can't help you much there, sorry.
[Android General] Mahesar:
How does it work?
[Android General] venso:
RESTORING BACKUPS

Another thing I found is TWRP sometimes seems to get stuck on restoring System Image or Vendor Image when restoring a backup, so I often skip these, or restore them individually from the rest of the backup.

Installing TWRP on the UMIDIGI_Power_V1.5_20190720 version and creating backups - the process is going fine. The problem only occurs when you need to restore the backup. Any section individually or all together - causes a cyclic reboot at the level of the Logo screensaver. Such a suspicion that TWRP creating copies of selected partitions - writes them incorrectly and therefore cannot restore them correctly. Unable to turn off the phone while holding the Off button. Neither 10 nor 30 seconds. I had to open the phone and disconnect the battery cable. After that, through Flash Tools, I again flashed UMIDIGI_Power_V1.5_20190720 stock firmware.

Interestingly, I flashed a new firmware via Flash Tools UMIDIGI_Power_V1.5_20190826 and this TWRP could not install on this firmware. Butlup again

Maybe nemo-nemo will try to make TWRP fixes?

At 4 pda there is a programmer: mehanik6

He collects TWRP for Android 9 and specially collected for our device for version 1.5. They sent me the last 2 TWRP files from mehanik6.

But I can’t test them - the phone is with my wife and she is in another city. In the first post, mehanik6 suggested making TWRP for version 1.5 for our phone.

https://4pda.ru/forum/index.php?s=&showtopic=947978&view=findpost&p=86995125

Maybe you can write him and he will give you a new version of TWRP - he only needs a tester for TWRP. His tester is sick and cannot test TWRP.

In the second link, an order was made to create TWRP for our phone version 1.5

He created it, but we need to test it.

[Android General] SeekerofLight.iz:
Sorry for the late reply. But I can probably try testing them.

The one thing that seemed to resolve the bootloop for me most of the time was restoring the "md1img" file from a previous backup from TWRP. But if you already tried restoring that individually, I can try testing these versions of TWRP to see if it has the same issues. The current version I have hasn't given me any major issues like the ones you described though, so I may return to it after testing these two.

In case you didn't know, when the phone is stuck in a bootloop, you can actually still flash it if you plug it in to your computer immediately after the screen shuts off and SP Flash Tool will flash it like normal. Basically just catch it in-between reboots.

I have yet to try the latest Aug 26th update with TWRP, so I'll probably play around with that a bit too as I am trying the TWRP recoveries out. :)

[Android General] SeekerofLight.iz:
Sorry, I said I'd test them for you but some things came up and I won't have the time. My apologies, but hopefully someone else will be able to.
[Android General] GBytesBlack:
Could you tell me if this process occurs the error Red State or Orange State ?, since I tried to install twrp the first time and occurred the Orange State system understands that I modified the boot.img and does not boot, then tried to install only magisk as You described and occurred the Red State which is the same thing as Twrp, says I modified a file and it does not boot, so please if you can answer me if you do not give these problems and which stock version you used. Thanks
[Android General] venso:
In this case, there is no such problem - you just need to flash this file and everything will be fine.

In post number 29 on page 3 there are these files

There is no cyclic reboot from this

https://xdaforums.com/showpost.php?p=80061885&postcount=29

What are these files?

LK: This file flashes over the stock lk and prevents the "5 Second Orange State" message at boot from appearing.

Note: The lk.img file provided is only confirmed working for the v1.5 update. (Provided by Chela_vek.)

If you have obtained superuser rights, then you can’t do the WI-FI update anymore.

Try flashing the phone through FlashTuls stock firmware and rooting it again.

Then the errors disappear
[Android General] GBytesBluue:
My problem is not that when I received the device it worked normally, so there was an update via normal wi-fi and I went to update, that's where the problem comes in the update just went into bootloop and was updating forever that's when I decided take the S_Flash_Tool and install his rom stock, the first time I tried it happened that it starts the rom installation and the phone would call out of the blue interrupting the installation of rom stock, that's when I decided to go to the Format tab of S_Flash_Tool and put the auto format option and he formatted it and I was able to install rom stock after that, only it happened that when he called and got into the Google account step he just wasn't going to be "Verifying Data ..." forever so I decided skip this step, but it got worse because the phone did not enter any password or digital, if you put a password it would be locked there in the password screen and when restarted the phone and you would put the password again said that already had a password and it was not the password I had entered before locking there, outside that the play store is still not entering, there were other bugs such as applications do not delete the data, the phone crashed, sometimes when you locked the phone and unlocked it was black screen and then I could not solve it at all, I tried to install other rom stocks and all still the same, that's when I decided to put the twrp and install a gsi and gave the Orange State problem there, but you have already found a way around it. I would like you to tell me if I did something wrong and I can install a gsi rom via this twrp because I am already out of options, and if not, could you please back up your rom so I can install it via twrp please, man. Sorry for my english i'm brazilian.

Hmmm, so it only works with version 1.5, plus which 1.5 more specifically, why has 3 version 1.5_20190826 version 1.5_20190720 and 1.5_20190717, so could you be more specific which of the three works?
[Android General] venso:
To turn the phone on the MTK processor into a brick or kill it - you need to try very hard. Everything is fine with you - only an error in Google Play --- you can clear the application cache and clear updates in the application and everything will work fine. You always have the most reliable option - through FlashTools - flash the firmware version 1.5. It will be a clean installation without errors.

The TWRPs that exist for our phone are not fully developed and are not yet reliable. You will not be able to restore with my rum via TWRP. You will get a cyclic download. Unfortunately, my phone is not yet in my hands, only in a week can I receive it. I can not test the last two TWRPs yet. You have only one way out and it is the most correct and reliable - to flash your phone through the computer with stock firmware.

They work all - I myself installed them through FlashTuls 1.5_20190826, versions 1.5_20190720 and 1.5_20190717
[Android General] GBytesBluue:
So I already tried to do that by cleaning the cache and the data from the play store, but it happens that the cache clears more when I put to clear the data lock the phone, I already flashed these two versions 1.5_20190826 and 1.5_20190720 via S_Flash_Too vcl and they give the same thing.

Could you send the Flash Tuls link you used? If possible call me on WhatsApp I need a lot of help.
