[Alcatel 1 Questions & Answers] jdd1996:
the boot.img is embedded to the rom, sometimes as a payload.bin or an encrypted file (Inside a scatter file) , usually located in /dev/mtd/ or /system/bin , and so on .

To READ the encrypted Boot.Img from the Rom you actually need to read The SCATTER FILE, SPD TOOL, or SP Flashtools are the tools that help you -- LOAD THE ROM and read the scatter file. You could open a whole rom on your own and browse the files inside and you will never find the boot.img , you have to open the rom as a scatter file, as far as i know.

With root you can actually extract the boot.img file if you know the location of it for example:

dd if=/dev/mtd/mtd2 of=/sdcard/boot.img

or

dd if=/dev/block/***** of=/sdcard/boot.img

The problem with these devices is that they dont accept flashing anything into it besides system.img

To allow to flash recovery.img or boot.img , you'll have to input special codes with a special software from the Alcatel Company (we don't have those, cuz they're not leaked)

What you did was trigger a lock, a block to the phone by trying to bypass that security code they placed onto the device.

You took the boot.img out, patched, and then placed back inside/reflashed it as an individual file, with spd tool or adb, if you did with a flashing tool then, this triggered the security of the phone, and maybe other img's got patched and flashed too (or corrupted) such as recovery.img, boot.img, vendor.img , product.img , etc etc, (these are all just regions of the ROM read through the scatter file) ( i guess this locked ur device)

Repairing it :

1) IF YOU can still access into fastboot mode (bootloader) somehow.

** I think just reflashing a new ARM ROM compatible with ur storage partitioning can fix it

(A only or AB )

(try booting the phone and then connecting it to the usb cable , to the pc, and doing

command: fastboot reboot bootloader

or fastboot devices

if you're lucky and its detected , or goes into bootloader you can just do fastboot flash systyem /name/of/rom.img

and this could flash a new rom and revert the boot.img, recovery and everything else to default

thus helping you boot ur phone again.

2) If you can't even access recovery or bootloader (fastboot mode)

** What i think you have to do to repair it is the following, REFLASH the full rom again onto the phone with sp-flash tool

GET the UNPATCHED Boot.img (i hope you made a backup of it), get the whole intact rom, (or any other compatible working rom) the scatter file intact and reflash the WHOLE full rom back again with SP FLASH TOOL

(forget about Placing the PATCHED boot.img in the scatter file) we wanna use the unpatched files, all virgin.

SP FLASH TOOL gives you an option to reflash A WHOLE ROM, i suggest to try reflashing the stock ROM (considering its good) or Reflash another Android ARM AOSP ROM, you can find plenty here in XDA, i can give you links (make sure to HAVE A GOOD ROM this could also be the reason your phone got corrupted, the boot img and files you were handling were probably already corrupted or flashing them simply broke the security code thats about it) that is why you want a ROM that is known, and good for any phone/tablet, preferrably with the same chip as yours or with enough reviews or comments from others, 90% of the roms we can find in google have viruses or are corrupted, specially considering its ALCATEL no one handles this, AND WE ALWAYS WANT TO MAKE SURE OUR PHONE ACCEPTS recovery.img, boot.img , etc without trigering any security codes, if you extracted your own ROM/stock firmware then its alright, thats fine. but you forgot about the security codes, you triggered those i think. Make sure that scatter file loads into SPFT without error, SPFT checks the PRELOADER and DSP_BL and if they aren't in the scatter directory, it will fail and maybe crash. the regions/files can get corrupted. Everything is in green, everything is setup, then you can click " Flash whole rom " this is what you need i think that way you revert everything to default , Boot.img, recovery.img all of it that got locked (you triggered the security code, i think so, because if it wasn't so , it would just boot loop, since yours boot loops and then WARNS you, it means you triggered some code or corrupted something)

3rd option return that Alcatel Toaster, to the company and pay them to repair it , cuz they have the softwares to do all this in just a few clicks.

The issue is the company, they suck hard, and all phones they make are low quality phones .
