[Q] Flash back to 4.1.27

Hi everybody,
I want to know how to flash back to 4.1.27 ? I made the terrible mistake to update to 4.1.57 before rooting, now I can't root neither go back.
I found this briefmobile.com/motorola-atrix-4g-system-boot-file-sbf-leaked but it can't detect the update after the installation.
I appreciate your help, thanks.

Please can I know something. Have you done something with your SP? If you have, please tell me what you have currently done. If you don't, tell me that you haven't done anything.

So you have unlocked a bootloader. Could you please tell me what method did you used to unlocked your bootloader? Did you use FlashTool or the "fastboot" command in adb?
And based on your first post, I have to say that you have lost your DRM keys. Without DRM keys Bravia Engine won't work.

Okay I get you and I have the prerequisites beforehand. Now please confirm your intention. Do you want to use 4.1 or Cyanogenmod?

I can't really give a suggestion. "Best ROM" depends on personal preferences. Since I am currently using CM11, I must say it works really great on my device. However, some people face problem with it such as being it laggy and everything. I hope you won't face the same thing.
Actually I have a guide that will solve your problem.
BUT BEFORE THAT please read everything there. Please follow the requirements. You may ignore any bootloader-related points. Since your bootloader is unlocked, you can skip guide number 1, and directly proceed to the section "Fastbooting DoomLord's kernel" in guide number 2. Then proceed normally afterwards. Get a CM M10 snapshot here. Psst, M11 is getting near!
Now you may go to the guide: http://forum.xda-developers.com/xperia-sp/general/guide-flashing-custom-roms-ultimate-xsp-t2888579

Yes if you want to downgrade you may just and only follow 1b. However needless to say, if your bootloader is unlocked, there's no more need to backup your TA partition

Your problem might have be something to do with APN. Just contact your service provider, and get an internet configuration. That will work for you
In Stock SONY, there is an-already method that will fetch internet config. Sadly there's no such thing in custom ROMs.
Or to make matters difficult, you can find someone with the same service provider like you, open their phone's settings, find "APN" in Mobile Networks, and copy all settings hand-by-hand to your phone.

how should i back to stock ?

hello everyone
i have a rooted n960f device with the alexndr ROM , since iwant to sell the device i want to unroot it and back to stock .
unfortunately when i trying to flash the stock with ODIN my device boot up without IMEI.
in order to fix that i need to ROOT the device again install TWRP and than install te ALEXNDR rom again.
these is the only way to get the Signal again .
do you have any idea how i can back my device to stock ?
thanks
guys ?
any idea?
please
You most likely just need to flash the correct firmware for your device and you do know there is no way to make the device stock again after rooting, right?

It's not a matter of you don't tell me, i don't know.!
It's a "matter" that before you root your device, to familiarize yourself, regarding the pro's and cons
of rooting.
To do research and then if you don't understand or want guidance regarding a particular issue /
"problem" then ask.!
Bottom line is....
no use asking afterwards if you didn't do your "homework" before.!
Good luck.

Question cant get back yo stock from pixel experience ?

can someone help pleasae , i have pixel experience on my redmi note 10 pro and trying to go back to stock but its failing . when tring miflash the progress bar speeds to green in like 1 second and nothing is flashed and mi pc suite cant detect phone
whats best way to get back to stock please
Simple, do the same as for every other custom rom. Put your Stock rom on your sdcard and go into recovery(process as usual a full wipe), then install stock rom. You have to install TWRP/Pixel-Recovery again ofc.
Sorted it now . Thanks anyway . I had to delete a few lines of a batch file that was preventing rollback and did it in miflash

That's a safety check. Bypassing that increases the risk to brick this device.

I didn't know that as he never said in tutorial . As I won't be installing an other ROMs and everything is working fine would I be ok to leave it as it is or should I download the ROM to my phone and install original ROM over the top via local storage ?

Xiaomi has implemented anti rollback to prevent switching to old builds. Recovery ROMs don't have this safety check but fastboot ROMs do have. Bypassing this might brick the device like many Note 5 pro owners bricked their devices by flashing older recovery rom which bypassed the safety check. If they'd have flashed fastboot rom their devices could have been saved.

Different question: Did you like the custom pixel rom? Is it worth to change it or should stick to stock rom? What issues you found there?
It's a good ROM the pixel ROM . Nothing up with it at all . I just felt I'd keep it stock . I didn't encounter any problems with it. Each to there own as they say . You may love it . Plenty of tutorials on YouTube reviewing it on note 10 pro

Yes, fine. ARB index should either be same or greater. Since it was same you're safe. All's fine. But be sure to check that index before doing this.
Thanks for that pal
ARB is not present with custom rom (aosp and miui) right ?
