Sorry, I got a concussion and haven't been able to do much, but really I'm stuck because I can't get it to connect to the computer at all. Not in Windows or Linux. I think he's messed it up beyond repair at this point. The offline root gave me an error around the mounting of the system, but that can be done if you can get the recovery to show up. It's one of the options. I was trying this method. HERE see if you can get it plugged in and to work. Also, Kingoroot gets to 90% on the apk alone. So the computer app might do the trick. Then you can switch it to su. Really a rooted phone can get a lot done with apps like flashify and flashfire that we can't do right now. If you can get even a temp root let me know and I'll tell you what I found out about the apps to unlock the bootloader, flash TWRP, Flash Magisk, then flash ROMs. If you want to try the variant route I was trying then just do a search on google. Some sound just as bad, but other similar phones seem better. You can pick which one you want to try. The phone I have got to a point that it kept deleting applications and stuff on the phone and has trouble with the sd card. So I don't have the stuff I had saved on it anymore. I'm giving him my current phone when I get a new one. It's too messed up to salvage. I hope you have more luck.

I need to unlock my phone U304AA
[General Topics] Aweston:
Ok boys and girls, in case anyone is still wondering here is how to root this sucker.

https://drive.google.com/file/d/1--Ul1ae73zcejNuJ1a7ftq5sTo2VP8Ya/view?usp=drivesdk

Comes with two files. Mtksu amd magisk be sure to use the magisk version included in the zip. Install mtksu then wmagisk, open mtksu and install the top magisk option. Reboot then open magisk hit install when it asks. Now open mtksu scroll to the bottom and hit activate and reboot again. Should be good too go at this point. Oh yeah be sure to click apply at boot in mtksu. Not sure if this had been posted before or not. Now, to find a way to unlock bootloader and install twrp.
[General Topics] sjjtnj:
Thank you, I tried Mtksu on mine and it didn't work, but it might've been the phone. I don't have one of these anymore, but I hope you all the best of luck. For the bootloader and Twrp try Flashfire or flashify.
[General Topics] jasonmerc:
MTK bypass method released by some smart dudes out there. I will test if we can use SPFT on this phone now. Stay tuned. This could mean root & recovery in a matter of minutes.

EDIT: It ALMOST works. Technically it bypassed the auth file as advertised. The only thing left now is finding a compatible preloader/scatter file to use.
[General Topics] jasonmerc:
Used a modified Moto E6 Play scatter file to pull images from the device. Tried flashing over stuff and got an error. Long story short my U304AA is now permanently bricked, so I'm tapping out of this project here

I do have recovery and boot images that (supposedly) work if anyone else wants to try and take over Keep in mind these were pulled with a scatter file from a DIFFERENT phone that's of the same chipset, so not everything is guaranteed to work. For example, the preloader was pulled with the specified parameters but I do NOT know if it's functional

Because I'm tapping out, and because nobody else seems to have anything on this, I'm uploading everything I can. Some pulls are too big to upload and some just won't work for some reason, but use whatever you'd like for anything you can. Hope I did something helpful

Well AT&T is giving away lots of Radiant Core devices because of their 3G shutdown: https://www.xda-developers.com/att-3g-shutdown-free-phone/

My wife and I just got one, so now I have two of these but I'm not sure I trust AT&T enough to use the "free" phone that they sent.

It would be great if someone can pickup this project, especially since so many phones are now flooding the market.
[General Topics] Aussie.Figjam:
I just got 3 of these "free" from AT&T. In fact I don't really need them, I just happen to have phones with an IMEI number that AT&T cannot decipher, so they sent me new phones just in case I can't use 4G.

Anyway, I'm trying to use mine as spare Google assistants scattered around the house, but because they run that crappy Android Go, the Go version of Assistant won't listen to me until I long-press the home button. I would also like to use them when I travel as a spare.

These things are essentially throw-away, so I'm OK to risk bricking one of them.

What I really want to do is install a real version of Android on here, has anyone managed to crack this yet?
[General Topics] kayshinonome:
I personally have been writing and reading using this tool https://github.com/bkerler/mtkclient, which is much simpler than the others

Its a little rough around the edges, but it certainly works

My final problem is disabling secure boot (I already have a boot.img patched with magisk)

It appears that fastboot is simply not a mode for booting on this model, so I was wondering if anyone knows how to disable AVB by hand with just partition images
[General Topics] luridphantom:
if it's possible to downgrade the firmware to before the october 2019 patch, it might be possible to mtk-su the device: https://www.att.com/device-support/article/wireless/KM1376142/ATT/ATTU304AA

might be another alternative to trying to disable avb on a locked bootloader
[General Topics] jasonmerc:
Not possible to do, already tried before when I didn't brick it
[General Topics] xxskylar_bleedxx:
Just got mine from this. I'd like to install something like NixOS mobile, but I've never used an android phone before. Will that be possible on this phone? If so, is there a good guide for newbs like myself?
[General Topics] jasonmerc:
If it's on this U304 Radiant Core, no. It is bootloader locked.
[General Topics] xxskylar_bleedxx:
is it possible to unlock it? I thought I heard something about that being possible
[General Topics] jasonmerc:
Nope. Thought it would be, it's not.
[General Topics] Jenniferdaniel:
AT&T RADIANT Core is a complete package with everything you need in an affordable smartphone. With a 5.5-inch Dragontrail display for added protection, and a 5MP rear camera with flash, capturing photos and videos are easy to share in a cinch. Up to 16GB of storage, plus up to 64GB more with optional microSD card, there is plenty of room for all of your essentials.
[General Topics] kayshinonome:
Can't you dump and modify the bootloader?
[General Topics] luridphantom:
i wonder if something like this will work to bypass daa and give root: https://github.com/bkerler/mtkclient
[General Topics] kayshinonome:
I think the only root this phone is gonna get would be another mediatek exploit.
[General Topics] luridphantom:
here ya go. mtkclient can unlock bootloaders now
[General Topics] luridphantom:
you can probably unbrick and unlock your phone now with mtkclient. the dev just updated the tool with bootloader unlocking capabilities
[General Topics] kayshinonome:
I'll go check that out
[General Topics] jasonmerc:
bruh

lemme go fish in the trash and piece mine together with tape to unlock the BL
[General Topics] kayshinonome:
Alright my bootloader is unlocked, now to root it
[General Topics] kayshinonome:
I ran into issues concerning the device actually booting after root, so I'll ask about it on the github

But having a unlocked bootloader is something
[General Topics] jasonmerc:
can you boot into fastboot/bootloader mode? if not, a BL unlock wont do much good
[General Topics] kayshinonome:
I fixed it with a proper vbmeta, but it isn't rooted, even after patching the image
[General Topics] kayshinonome:
Maybe I should just try to make a twrp image....
[General Topics] luridphantom:
nope but you can use mtkclient to flash for you. think of it as a more powerful cmd line version of spft

problem is there is no ramdisk in the boot.img so the recovery img will have to be patched. either twrp or magisk from recovery i guess...

haven't tried rooting it yet but will try when i get the time. attempting to boot magisk patched recovery images is a pain in the ass
[General Topics] jasonmerc:
Okay I'm going to cook up a dirty ported TWRP Recovery for you guys to try out on this U304AA. The sheer amount that I'm pissed off (at myself) for throwing this away is giving me the desire to see this through and help you all out.

This will be risky since there's no stock recovery image for this thing that we can confirm works, but if one of you is willing to take a risk let's get this ball rolling.

Please remind me of the following things before I can make a dirty port of TWRP recovery:

1) the chipset (MTK67XX, I need the full thing with the letters at the end if applicable

2) what mode that Android on the phone runs in, tell me if it's 32 or 64 bit

3) The actual version of Android it runs, I believe it's 9.0 Pie but just confirm that
[General Topics] jasonmerc:
Oh wait I didn't see your post there, if you want to try to whip up a TWRP image first I'll step aside and let you have at it
[General Topics] kayshinonome:
I'm using the recovery partition from the device

It's compiling at the moment
[General Topics] kayshinonome:
Well it boots, but mounting seems to not work

I have my configs and my recovery here, but be warned it might break your phone lol
[General Topics] kayshinonome:
Update on this: Only certain partitions are unmountable, probably due to a bad fstab
[General Topics] jasonmerc:
As long as /boot and /system are mountable that's enough to flash Magisk. If you can boot into recovery, do an adb sideload magisk.zip and reboot, see if it works then

If /system is also mountable, then in theory, this SHOULD be enough to get GSI's working on this thing too. Like custom ROMs but no source code needed. I believe (if i recall correctly) you can flash custom GSIs in TWRP instead of bootloader if you want to. But that's obviously a lot riskier
[General Topics] kayshinonome:
I checked and data is the one that doesn't work
[General Topics] kayshinonome:
But note that sideload does not work for whatever reason
[General Topics] KJ7LNW:
Is it encrypted? It would make sense to encrypt /data for the user...
[General Topics] kayshinonome:
I don't know..., I'll check later, but nothing else is encrypted I believe.
[General Topics] luridphantom:
1) mtk6739

2) i believe 32 bit

3) 9.0 pie go edition
[General Topics] luridphantom:
here is root but it seems to disable my imei and usb for some reason, maybe it's the alpha build im using posted on bkerler's github
[General Topics] jasonmerc:
Try this zip to disable force encryption

Go into recovery, do Format Data (not the same as Wipe Data) then flash this zip and reboot

https://xdaforums.com/t/universal-dm-verity-forceencrypt-disk-quota-disabler-11-2-2020.3817389/

If you read the instructions on that page it tells you to add ForceEncrypt to the filename to have it REMOVE force encryption. So what this means is, you'll need to format /data like I said above, then copy it over to your phone via MTP in TWRP or something before flashing. The key is to preserve the filename, so no side loading because ADB sideload always renames it to sideload.zip
[General Topics] luridphantom:
weird, mtp doesnt work for me and my other methods of using a sd card or otp flash drive don't get mounted either

any way to get twrp to mount those?
[General Topics] jasonmerc:
We'd need to build from source, which isn't going to happen

Try to sideload the following zip (format data, then sideload this here, then reboot). This one SHOULDNT need you to rename anything so you should be fine

I didn't make this zip BTW, but uploading it here for archival purposes
[General Topics] kayshinonome:
If mtp doesn't work, adb push did

I don't believe sideload worked either

Installing from zip seemed to be my only option
[General Topics] luridphantom:
got an install failed from trying to install the zip after adb push
[General Topics] kayshinonome:
Weird. Did the zip fail on trying to mount data?
[General Topics] luridphantom:
this is right after i hit format data in twrp
[General Topics] luridphantom:
the only way to get root for me is to patch the recovery with magisk and boot into it but then my imei seems to blank out when booted into the rooted state
[General Topics] kayshinonome:
I'm starting to think you can't get to /data at all in my image...

But figuring out why is beyond me
[General Topics] luridphantom:
its all good, i can live with a semi untethered root by booting through recovery

thanks for trying to build a twrp image though
[General Topics] kayshinonome:
No problem, just hope a pro comes along and fixes this all up
[General Topics] jasonmerc:
Can you extract the boot image directly from recovery? Post up a boot image here, maybe we can patch it directly. I can try to do a direct patch with Magisk or the no verity thing or something, then you'd just reflash it back to the boot slot via TWRP again and see if it boots
[General Topics] luridphantom:
heres the stock recovery and magisk patched one i use, build number p00610 release
[General Topics] jasonmerc:
I was going to do this on my own but it turns out I need a phone that isn't rooted. I'll post up the instructions here for you guys to do then.

The Magisk app can actually disable DM-Verity/encryption for you. Go into unrooted Android and go into the Magisk app (again, on an UNROOTED phone, so that means one that has the Magisk Manager app installed but is not Magisk patched yet). On the Magisk app homepage there will be an Advanced Options. Uncheck everything, specifically the encryption and verity check boxes. Then tap to install magisk, and select to install Magisk onto an image saved on your storage or SD card. Navigate to the image you pulled, wait for it to finish patching that image, and then reboot to TWRP and flash that new patched image to your boot slot and see if it works.

These phones on eBay are about $20 and readily available. If you need an original phone to test or want one to play with then just search for "at&t radiant core" and get as many as you'd like for hacking on.
[General Topics] mrmazak:
I skipped pages 2-4. So did i miss it? Did you fix your bricked phone, or did you get another one?

I just got a message from art and they say they are sending me this pos phone. Because they say my G90 is only a 3g phone and they will turn it off soon. Those bastards. Anyway looks like maybe root is done already.

And flashtool is working (at least with bypass)?

NVm, i went back and got caught up. Looksike few dead ends here. I still have a pie build environment available, saw "mtk client" mentioned in thread but have heard of that before. Maybe need to check that out
[General Topics] dggsafrebgvvvvvv:
can anyone help me i have a cricket vision 3 u318aa and i can't figure out how to unlock the bootloader it has no enable oem unlock in devloper options and the bootloader is locked. or atleast figure out how to get this phone rootted. this phone has android 10 go an arm processor. i can use fastboot and adb commands when enabiling Allow AT commands under usb debugging in devloper options.
[General Topics] jasonmerc:
Wait, I believe that the mtk exploit has been expanded/enhanced. If I recall correctly, someone DID manage to unlock the bootloader. Reading this on mobile now with bad data so I don't want to scroll back and look. But from what I remember someone DID get it unlocked. The only challenge now is actually getting custom firmware on it.

I do not have mine anymore. Me and my college friends played hockey with it on the floor after I thought there was no hope. But, it was worth the $13 I spent on it!

If you need any help though, I'll try to do the best I can despite not having one. Good to hear from you again btw!
[General Topics] mrmazak:
I read on the first page that @lopestom provided dump files. That should mean he has spft reading from device. I assume. If this is the case things might look good going forward.

Update:, nope, he did not pull with spft, only found link to other user, who has not responded. So not so helpful there.
[General Topics] mrmazak:
Well it turns out art sent me a different phone. A Calypso U318AA.

Similar, it has mtk, and bypass is doing it's part, bypass auth file, but I'm stuck at "invalid preloader format"

Hint,

Try again with official build!

Wtf. Lol.

Maybe I'll get it connected eventually
[General Topics] mrmazak:
Update:: MTK_Client is working to read partitions. ... Yay.

When it's done I'll see if unlock works . ... Not sure why to bother with unlock , if fastboot is broke. .. well will see in little while.
[General Topics] mrmazak:
I just got the "same" model. U318AA, from at&t. They sent it because 3g shutdown they said. Whatever. My old phone was 4g-lte but they do not recognize it as such because i didn't but from them.

Anyway, i am working on same thing. "Unlock bootloader" and "root".

I have mtk client pulled all partitions, and will put together twrp. But if cannot confirm bootloader unlocked, might be risky to try and flash it.

Will keep you updated. Or at least will reply in this thread. Lol

Update:

I jumped right in and used mtk client unlock feature, and guess what happened to my phone.,,...............,

Yup you guessed it. I now have an unlocked bootloader on my Calypso (U318AA)
[General Topics] jasonmerc:
Can you post that MTK_Client thing? Whatever client you used? It seems like it works better than SPFT.
[General Topics] mrmazak:
it is better. I have only used it once, but i already love it. lol.

spft was failing to connect for me on this device, even after mtk-bypass.

here is the github page for mtk_client

[General Topics] mrmazak:
do you mind tell me which branch you build this from.

I find the trees made from twrpdtgen make tree for A9 branch,

this device and mine also(Calypso U318AA) has --dtb build flag so needs A10 branch, or because A10 deprecated need A11,

when i build there the image has not booted.

OOO< I just saw it, your config is useing header version 1.... AND radient came with android 9, my mistake. I received the calypso from att instead of radient (they told me they were sending radient) and calypso comes with android 10. so mine and yours are similar but different.
[General Topics] habeebo:
sorry .. but I get U304AA att with imei unknown how can fix
[General Topics] mrmazak:
does it return when flash stock boot.img?

I flashed phh phusion aosp GSI and it has root built in and I had no issue with loosing imei.

looseing imei seems to happen often when using "custom" build of magisk. likely to work normal with official build of magisk.\

Not 100% but better to try official before "special" hacked build.

I know this thread is a little on the old side, but if you still need the firmware i have a few of the partitions saved on github (boot, recovery, a few others) but I can upload the rest to an external host (the system partition in particular is fairly large). Private message me if you need it. Anyone that needs to root/mod/unlock bootloader can use MTKClient.

MTKClient GitHub : https://github.com/bkerler/mtkclient.git

I take no credit for any of MTKClient... That's WAY out of my league....

On a side note, devs really put the work in, donate if you can 'cause it's worth it....

[Xiaomi Poco F1 Questions & Answers] amitthehero:
So a little bit of background , I was using pitchblackrecovery on my poco f1 and crDroid as my daily driver but then I wanted to flash the oofgang Oneplus 7 port rom. So I flashed their TWRP and everything else but the rom wasn't stable (you had to flash system,vendor etc etc separately) as it wasn't working that well so I switched to arrow os 11.0 + d8g kernel now the phone is also not booting neither the recovery. So I thought of going in fastboot method but my linux machine keeps saying "<waiting for any device>" this was a problem while I was trying to unlock the bootloader also but it was miraculously fixed. I am using linux as my main driver and can't switch to windows as its just to much hassle . Any help would be very much appreciated.
[Xiaomi Poco F1 Questions & Answers] callmebutcher101:

[Android Q&A, Help & Troubleshooting] BulldogBarn:
I have this phone and now it wont boot. Im thinking there is no OS to boot. It tries and says DM varity disabled at top of screen then says software cant be checked for corruption /bootloader unlocked. When in bootloader there is no recovery to boot into as well when plugged into desktop . ADB devices command is not seeing it. So my question is where do I start to install recovery and make PC (adb/fastboot) recognize device. If I could get adb to identify device shouldn't I be able to fastboot boot (twrp-disc.img) then flash twrp.zip then reboot bootloader and flash factory ROM and kernel or custom? Hate if I sound like a noob im learning all I can. Any help is greatly appreciated!
