Try this many people reports to be working on most a125 variants

[fixed] rooted a325m suddenly no imei, no sim

I rooted my a325m by patching the stock AP file with magisk, had to use FRP hijacker by hagard to be able to flash the patched file. I root uninstalled several apps for debloating. The phone worked fine for like a couple of weeks, and now...

Thanks for sharing the method. can I unlock the region lock to use any sim card? and the unlocking tools seem paid and it has a minimum 3 month subscription which i don't need. do you have any free mtk bootloader unlocking tool?

i know its been a while but ive unlocked or unlocked/rooted an S5 , Note5, and A6 , exactly why is it neccesarry that i risk destroying my phone by opening it up and messing with the hardware when tools like mtkclient with bootloader unlock and patched odin to flash software exist?

There has to be a way because I have the same model and it's a TMobile or MetroPCS phone. Def not boost , I'm trying to find a way also... Showing a picture of the guts of my phone and saying "test point" doesn't tell me anything at all. We need actual instructions that don't assume we're electrical engineers..... Only thing I can think of is I know there is a 7 day timeout before you can even enable oem unlock in dev options so if it hasn't been 7 days or you haven't enabled that yet that's the problem.

ive spent all day just trying to get into brom, all over the internet not a single video or article with clear instruction, all they are doing just connecting the testpoint plugging the cable and boom brom mode.. and mine doesn't say anything it just boots into download mode after 5 seconds. i even tried opening the metal shield of the chip back on the board to find clk resistor still didn't work. what a frustration! well, 7-day timeout might be the case. Oh, Samsung

This is why you don't buy mediatek XD or Samsung for that matter lol we need a new OnePlus now that OnePlus went mainstream

I'm assuming you guys are on the newest firmware. Samsung patched up BROM mode in the February 2022 security update, that's why mtkclient or in some cases testpoint will not work, my A21 does not enter BROM anymore as well after that update. Try downgrading to this firmware: A125USQS3BVA2, that's the January 2022 security patch firmware and is not patched up.

God bless you , I can just downgrade like that with Odin? I thought Samsung could only move up in binary number when you flash, never down ? But if so that's awesome. *Update* yeah that didn't work lol still won't go into brom and still no oem unlock toggle... It took the firmware tho so there's that

If the older firmware is the same binary number then yes you can downgrade. In your case the binary version is still 3 so you can downgrade. For my A21 I can't downgrade because the old firmware is on binary 5 and the patched firmware it is on now is binary 6.
