[xt1068] Moto G 2014 bricked more than once, which stock firmware to use?

Hello all, a while ago my Moto G runnning CM 12.1 suddenly crashed, got stuck in bootloop and upon factory reset it got bricked with access just to the bootloader. I brought it to a friend who was able to install stock firmware and then CM 13, the phone worked fine for a few days just to have the same issue all over again.
I did as he told me, and basically went through the process of flashing stock firmware as per this post., but it fails when flashing motoboot. My friend said he "bombed" the device with all the (failed) commands anyway until the phone was completely dead for a few hours, then recharged it and was finally able to flash the firmware. I tried doing the same but I never got past the motoboot bit as mentioned above.
I used
RETAILDSDSALL_XT1068_5.0.2_LXB22.46-28_cid7_CFC.xml

I've scoured many posts but haven't really found any specific answers as to how to identify the correct firmware out of those up for download, I can provide other info if needed. The phone has been revived before so I guess it is doable again, thanks for your help and have a good year everyone! :highfive:

I forgot to mention that after this tutorial "android-help. de/forum/xiaomi-mi5.2683/loesung-xiaomi-mi5-starting-no longer-bricked. 808091. html" I have a connection to my smartphone. But the tool doesn't recognize Rom.
Update:
The Flashtool could now successfully flash the Rome to the Xiaomi. However, the phone still won't start. The only thing that the red LED lights up when you plug it in or try to turn it on.
Anybody else have a tip?
Update:
The Phone is running. Thank you

[HELP] Bricked Nokia 7 Plus TA-1055 (single SIM)

Hi all, I've an italian Nokia 7 Plus TA-1055 single SIM.
I was on Oreo 8.1, unlocked bootloader, tried many GSI roms for tests and then I wanted to came back to stock rom for some phone call problems.
In order to do it, during my tests, I did a big mistake, I relocked again the bootloader with fastboot oem lock command without having stock boot, but one with TWRP inside instead :crying:
Now, at every boot, phone shows me a message like this: "Your device is corrupt. it can't be trusted and will not boot[...] the device will shutdown in 30 seconds[...]".
Now, I can boot in download mode, but I cannot flash or boot anything via fastboot, in order to unlock again, and even "nb0 tools FIH Mobile" could not help me (like many others, stucked at "Reflashing service boot" or similar).
Now, what can I do?
Thanks for who wants to help me, every help is appreciated

Download Odin, download your phone specific Android 11 firmware file from a reliable site like Sammobile and extract it. Use Odin to flash A11 firmware (select CSC and not HOME_CSC) after putting phone in download mode. This will force a factory reset and you'll have to set up phone from scratch, but you'll be back to Android 11, stock firmware.
Detailed guides for the above procedure can be found on xda as well as YouTube. The process is the same across all recent Samsung phones, just be sure to download the correct firmware.
@enigmaamit, thank you for replying. I got all that. However my question would will this bring back the phone to the same way as I have bought it from the carrier! because since the update, every time my phone boots it doesn't have the carrier logo anymore. Yes I'm not a fan of carrier locks or logos on phones. I just wanted to restore the phone to where as I just bought it. Thanks again for replying

Only way to be 100% sure it works is to try it out I guess. If you're really unhappy with A12 and want to go back, I don't see any harm in trying.
What disappeared? Like what issues are you having? You will probably run into a lot of issues trying to install 11 after installing 12. ESPECIALLY the Ota 12...

Official OTA issue

Hi everyone, about 2 years ago I bought a Realme 7 Pro and I always received the official OTAs ... while Android 11 was officially released I downloaded and installed this version from the Internet: RMX2170_11_A.41. Probably this caused some problems and from that moment I no longer receive OTAs ... there is a way to downgrade and go back to the very first version in order to get back to normal and receive all the updates including android 11 and 12 ? Thanks a lot to anyone who will be able to help me because I don't know how to solve ...
P.S. i have already done a hard reset and a factory reset but nothing has changed
Thanks you for the collaboration
