How to root Cricket Wireless Alcatel Idol 4?

Hello! I've been searching the net far and wide for a way to root my Alcatel idol 4. Its the cricket model. I was able to unlock the boot loader and turn on USB debugging but besides that I haven't had any luck rooting my device.
Has anyone tried and has success or know any methods that could work?
Thank you!

How did you unlock the bootloader? I'm not able to do it. Fastboot doesn't see the phone when I boot to bootloader.

It's in the developer options called "OEM unlocking" 5th option down from the top.

That's been done since I got the phone. Still doesn't make a difference, fast boot commands have been stripped from this phone.

try this SETTINGS>BACKUP AND RESET>DEVICE RESET. this will restore all settings to default state while keeping dev-ops and all apps and data

Sorry if I'm speaking out of turn, as I'm not highly experienced...>BUT, I went thru what your referring to with my OnePlus phone. The option in the developer options that says "OEM Unlocking" for bootloader is nothing more than an option in the Android system that allows the bootloader to be unlocked should the mfg allow it. Whether this is on/off makes no difference for this being unlocked. It just has to be turned on for the unlocking to work. I had this Idol 4 for a short time but returned it due to the fastboot commands being removed.

Question Is the SM-A125U different?

Is my A12 (a125u) different and unable to be bl unlocked/rooted, etc? It has OEM unlock in dev options....?

Did you figure this out? Looking to do the same... Also can't find a firmware for it, please share what you did if you had success. Thanks!

Yes, the A125U has OEM UNLOCK in the developer options......you can turn that ON by going into : settings > about phone > software information ...and then tap BUILD NUMBER several times until you see that you have enabled "developer options". Then you go into developer options and turn on OEM UNLOCKING.
Before updating firmware recently OEM UNLOCKING was greyed out. But now I can switch it on. Now the question is, can this variant be properly bootloader unlocked and rooted. The known repository for downloadable firmwares for Samsung phones DOES NOT seem to have this variant firmware for download. And I wonder if that is required for this to be properly rooted.

Galaxy firmware has the firmware for this variant. I have the att version and I can't seem to unlock the bootloader. Holding volume up in the download screen does nothing. Any luck?

Bump, I have all same questions.... Anyone figure anything out?

Before I had tmo Sim unlock my phone the I set the oen unlock to unlock now its not there at all

Anybody rooted this yet ?

anyone know the interchangeability of the firmware between the a125u and other versions

I wish to know as well

What if the OEM unlock not showing how do you get it to show

I'd like to know this too. I believe the internal are all the same for the MediaTek devices. I got a SM-A125F for free and want to use it in the US. It looks like I could if I can convert it to SM-A125U or MS-A125M. I already bricked it once trying to flash U firmware and has to flash back to F

i was able to root this sm-a125u very easily... downloaded A125WVLS3AUL1 firmware (canadian unlocked) flash the full stock rom and was able to unlock bootloader as simple as holding down all buttons when going into download mode, it unlocked it that way and was able to flash twrp, magisk and its all good

I have a similar issue but vice versa. I bought a US version (SM-A125U1) only to find out months after that the dual sim option is locked and i think the only way to unlock it is changing the firmware. Now I need help to know what I can do to, please.

Question How to unlock bootloader?

I just received my Flip3 (SM-F711U1) and would like to unlock my bootloader. However developer options is missing the OEM Unlock option. It's completely missing not just grayed out. I read a few articles about needed to change the system date but none of those guides changed anything. Can someone help?
Also, I attempted to call *#*#7378423*#*# to double checked that it wasn't already unlocked and I got a popup saying "Unabled to process the request."
Thank you.

Have you tried through fastboot? (fastboot oem unlock)

Oh, got you. Sorry!

As far as I'm aware samsung devices don't support fastboot. I did attempt to connect it in case I was wrong but was not able to get fastboot to recognize the device.

You can try directly unlock without ticking the oem unlock. By boot into download mode. The other thing is your device or carrier or country wont allow your flip 3 to be unlock. There last step you can try is clean flash via odin with your latest firmware.

I can get into download mode fine but don't know how to use that to unlock directly. Can you give more details?
I tried a clean flach with my latest firmware but it didn't change anything.
It's a US carrier unlocked version I bought directly from Samsung. CSC of XAA. Currently using a T-Mobile SIM.

If you had them enabled on your last phone and you restored from your Google backup, developer options will be enabled. Has happened on all of my phones since Android 9

If you can boot into download mode there is an instruction just press vol up button and it will prompt do you want to unlock bootloader mine is like that. Im not sure yours since mine is korea version.

They support bootloader unlock. samsung dont support using fastboot unlock or command at all

if you're in North America, Canada etc Qualcomm chips there do not support bootloader unlocking, at least the Samsung one's don't, not sure about other OEMs.

They used to, so there was always a possibility it returned.

I recently read this article on XDA about unlocking the boot loader on the Fold 3 which results in Samsung disabling the camera (WTH?), Is this a thing on the Flip3 too?

My device is rooted. I have always been able to find the OEM unlock option under developer options without any constraints.
My camera is NOT affected. I can still use it without any issues.
I have an European device (SM-F711B).
Hope this helps some of you to track down whether this is a location or carrier based problem.

Hey Redhatter,
Out of topic question, but are you getting Tmobile 5G just fine?

Thank you for sharing, I’ll give it a try

To root a phone's Android unlocking its bootloader is NOT required.
You simply have to add SU binary to Android's filesystem and make this binary executable.

I want to oem unlock bootloader for trwp and roms but I can't find oem unlock in dev settings and tried the video above and a couple of other things I found

You need the Samsung flash tool and the version of android for the phone and su +twep+magisk is optional good luck
Ps. Allways back up everything!

And I'm fixing the Samsung flash tool is PC only correct? My **** got stolen like a few weeks ago so I'm trying to figure out how to do this **** without a computer and it's a pain in the ass pretty much impossible.

I am having this issue and can't find a resolution for it anywhere.
Boost Galaxy a13 5g android 12:
No OEM unlock switch available...
The trick changing the date doesn't work at all...
I am not trying to flash custom ROM, just to tweak the system kernal settings.
I seen someone mentioned to root w/o the OEM unlocking switch available, all that is needed is to flash the SU binary with Odin.. I haven't tried this yet but I am almost positive Odin for windows doesn't even read the Samsung devices without the bootloader being unlocked.
Anyone care to chime in here? i'd be very appreciative!
Mainly WTF is the OEM unlock switch not available on my device. I actually have 2 of the same devices and both are without the switch.
Also would flashing SU work and do the trick?
Any other useful information you could send my way would be really helpful too.

Maybe who's find how to unlock bootloader on this device after July update?

General re-locking bootloader problem

I tried for my first time to unlock my phone's bootloader and thought it was something really easy to customize the
phone firmware on the other hand was not what I thought and I don't know much about computer science or customizing a firmware;
and then without being able to install a root or any modification I decided to re-lock the bootloader (because i dont want it anymore) only that I did not succeed with various tutorials and I did not find any for the samsung galaxy a12. I just unlocked the bootloader from developer options settings and ran what the tutorial said on how to activate it without installing a root or customization of anything.
can someone please help me.

Well it shouldn't be hard really. How did you unlock it in the first place?

Wait, is it really so hard to lock the bootloader on Samsung devices? Makes me think twice about buying one now if I can't simply lock it with a command like fastboot oem lock.

It's not hard to relock as its not hard to unlock it.
If you've followed any unlocking bootloader tutorial, after enabling OEM unlock option, you have to enter downlod mode and long press the volume up to enter unlock mode and then procedd to actually unlocking it.
For relocking it, just go to the download mode again, then long press the volume up and you'll have the option to re-lock it.

Samsung phones have a download mode instead of a fastboot mode, so you can't use commands like fastboot oem unlock
