Hi to start id like to say F androidarea51.com they are little cry baby's on a power trip and banning ppl like crazy for no reason...anyways i have recenty purchased a Alcatel LTE One Touch Sonic on 4.1.2 and have been trying to find some help porting CWM to my device. I have MANAGED to pull the boot.img,system.img and recovery.img from my device. I rooted with SRS-Root which can be found here http://download.unlocksamsungonline.nl/~xtrusion/SRSRoot-Setup.exe
I have uploaded and decompled system.img,boot.img and recovery.img which can be found here http://www.mediafire.com/download/2nt0nt9tjrw449f/AlcatelIMG.rar
Once you open the extracted recovery.img you may notice that the fstab is a lil different than lower version android OS's and does not list the partitions name...I will provide a txt file within the next couple of days with the proper partition names and mmcblocks...
If anyone is willing to help me port CWM for this device please feel free to contact me via email or reply with a comment
[email protected]
Ps the system.img has been slightly modified it is rooted and is not stock...I changed some props to change the android OS version id and device id..

I managed to get adb to work with full root access with the device powered off! the downside is there is no working recovery..i wiill leave a download link if anyone would like to see it for themselves however I AM NOT RESPONSIBLE if this ruins your device..Neverthe less im 99.9% positive nothing bad wil happen to your devices otherwise i would not leave a download link to it...

Alcatel one touch sonic
I used kingroot to root my Alcatel one touch sonic, but now that I did, do I need the CWM or the other recovery app? Also, how can I flash my ROM? OK still can't find much on this. Did you get that cwm to work? If so could you dumb it Down lol! This is my first root
Hello There
i just brick my phone trying to get rip of a gosh virus wich installs apps on system...
and well now phone is stuck inTracfone logo

adb fastboot or fastboot flash system system.im is not working
if u can help me pliz that will be nice ><
How does one edit the bootsplash for metropcs lg f60 (ms395)?
I've seen other posts that say to flash a raw image to the
Code:

Guys as i said i will try to port MIUI to MI A1 but we have some problems that i don't know how to solve it so i need help from other people/devs./testers..
We have same Hardware like 5x only problem it's Partitions that we have some other partitions that 5X doesn't have like (system_a,system_b,boot_a,boot_b,modem_a,modem_b,and others..)
You can see the Difference Below

My First Idea:
We can push parted to our device and from recovery we can remove the partitions and create every partition from 0 like 5X then we will need someone from 5x to backup their partitions and flash it to our device (first backup yours ) but there's high risk for Bricking our device but 85% after that MIUI will work
My Second Idea:
To Download MI 5X firmware and flash using MI Flash but as i see in the folder images there's file partition that shows all partitions (in that file there all partitions on list but some of the partitions are missing fsc,ssd and other so i think if we add them maybe we can boot it but i'm not sure) also i don't know does MI Flash is Repartitioning Our Device or just Overwrite the Partitions also there's gpt_backup0.bin file that backup gpt partitions so maybe we will have issues with that also we will need to modify some other files..but this is highly in danger we can brick our device totally
My Third Idea:
To someone create tool or find tool that can automatically repartition our Emmc with 5X partitions in Download Mode or Fastboot but i'm not sure about that
Also i will need some Testers
That's it

Umm better u can define the partitions in updaterscript itself

Uhm I'm not really familiar with development per se. But can't you just install it on our partitions and symlink it accordingly? It'll probably slow everything down a bit but I prefer to not play around with partition tables other than for treble because that is the easiest way to get your phone hardbricked.
Or you can try to create repartition script just like lanchon created for galaxys 2 i9100.

Just an idea
Comming New Alpha Test i'm uploading now i will post also i'm 75% sure that will boot just flash at twrp but first wipe everything Flash at your OWN RISK!!!!
Do you tested , do you have the phone ?

Please stop porting features to a phone you do not have! It is very likely that you simply brick other people devices!

If it's possible to make a great kernel without device then he doesn't have mi a1...???
I contacted Guy who already ported MiUI for our A1 but he have issues with setup wizard he will upload Tomorrow on XDA atleast it boots[emoji41]

He made the Extreme Kernel for Mi A1. He knows what he's doing.
I'm really excited about having So much variety on this device, like MIUI android one, Lineage, pixel experience.. it's such so good and i learn a lot, thanks to all the devs and people that make ROMs possible.
You can have partition table with usual fdisk tool, or via EDL mode in MiFlash (the associated XML will write partition table).
Just be sure you backup all partitions with EMMCDL first, and are willing to disassemble device for testpoints method if or when you brick it
I've been meaning to port MIUI too btw, but my #1 priority is Project Treble support, and I will be making it a Treble-enabled MIUI GSI instead. I'm kind of waiting for stock 8.1 to launch officially before I go full throttle with it, and/or the Mi 6x to launch (it's the only Treble-enabled MIUI device that has similar hardware to ours, as far as I know).
I've ls the symlinks, but i'm not able to say which one is the recovery partition.
Can anyone explain the list for me?
