Phone bootloop logo and doesn't format - Android Q&A, Help & Troubleshooting

Hello all i have this problem that is bugging me for months now, so my phone suddenly went into bootloop and it's not my first time with this phone doing this but from all the 3 past times i had the bootloop i fixed it by flashing the stock rom and there was only 1 time that my phone got stuck on the green recovery android and i just plug it in my pc and everything worked fine (yes it was weird for me but at the time i thought it was normal).
So now bootloop happen again and i tried reflashing with the stock rom like i used before with spflash tool and i'm always getting stuck on "format 0%" and i get the error of "st_format_" something like this so i tried using fastboot to flash every single image and nothing worked, so after all of this i start to try all kinds of things i found on the internet like, using the fastboot "boot boot.img" and nothing worked i would just get a thing saying "writting boot..." and only would receive a message when my phone battery would be drained out.
So i'm here asking for help if someone know's what's wrong with my phone anything is helpfull, i can provide some info from my phone if anyone wants i will try to add some files with information about my phone.
Thank you.
Phone: Qilive Q4 7" Auchan
CPU: MTK6582
Things i tried:
Miracle box
fastboot using flash/boot/oem unlock and still nothing worked however when i typed "fastboot oem unlock" i would get only 3 dots with infinity waiting time till phone battery would be drained out.
another random scatter file for spflashtool only changed the img names
tried spflashtool to format all except bootloader and still would come with an error of format error and even with the "download only" option i would get an error.

[Q] Trying to unbrick LG optimus V, bootloader not working

This thread is referring to this method of unbricking:
http://forum.xda-developers.com/showthread.php?t=1226470
I am having the same issue from the OP. However, when I get to step 3-5 where I use "adb reboot bootloader", it doesn't bring me to the bootloader (blue screen). At first when I tried to time it right, I got "device not found". However, as I tried more often, the command seems to go through as it returns blank, but the only thing that happens is the phone reboots and displays the "factory reset...formatting data...formatting cache...do not remove batttery...rebooting" again.
I've tried about 20 times now and, instead of bringing me to the bootloader screen, it keeps rebooting everytime I use "adb reboot bootloader. I would appreciate any help I can get.
I started a new thread because I cannot reply to the original thread as I do not have 10+ posts yet
I was thinking maybe I can't boot into bootloader since it cant even boot into recovery? Is that possible?
I'm in the exact same boat as the OP.

Evercoss A28b Stuck At "Setup Wizard Has Stopped" After Factory Reset

After factory reset I get "setup wizard has stopped" but I'm not able to flash my rom
Hi all
this is my first post so please be nice to me if I do something wrong.
Ok, where to begin with my long list of problems...
1. I have an Evercoss A28b bought in Indonesia but manufactured in China. It has Mediatek 6972 and SW version is ALPS.JB3.MP.V1.40 (that's what I could find in the phone's factory mode)
2. I rooted it 2 months ago and put all my apps and data on it from my old phone with Titanium Backup. I had some minor problems in the beginning but fixed them all and the phone was running smoothly.
3. This morning I froze "Go Launcher Z" because I didn't like it anymore and wanted to try how my phone looks withour it. Since the moment I froze the app nothing happened. I couldn't access the home screen or the app drawer but only my recently used apps when pressing and holding the home button.
4. I wanted to reboot my phone but it kept booting and booting, saying "android is upgrading" all the time. After one hour I took out the battery and now it's dead.
5. I tried to reset it into factory mode and first it seemed to work because it asked me to do all the settings like language, google account etc. As soon as I was finished a window appeared with "unfortunately setup wizard has stopped" and now I can't even see my homescreen or anything. My screen is black apart from the battery, wifi and SIM icons in the top right corner.
Now, what I tried to do:
1. I googled and found a few solutions saying I should flash my rom. I googled and found the sp flash tool and a rom for my phone.
2. SP Flash Tool did not recognize my phone and there was no scatter file in that ZIP file that I had downloaded.
3. I downloaded MTKdroidtools to try to generate a scatter file from my phone and a lot of different drivers but none of them made my phone connect with DroidTools.
4. So I went back to SP Flash Tool and googled for hours in order to find a scatter file and make my phone connect with SP Flash Tool. I managed to find another rom, this one had a scatter file in it and I also managed somehow to connect my phone with SP Flash Tools. It was only recognized after I had selected the scatter file and pressed the download button though.
5. SP Flash Tools brought an error message saying my pmt has changed and I need a new one or something like that. Unfortunately I can't even re-do this to give you the correct error message because I can not connect my phone to the PC any longer. Everytime I do this with battery or without it keeps connecting and disconnecting all the time.
6. I am at my wits ends and don't know what to do any more.
Please help

Huawei Y550-L03 LOOP Restart

Hey, I think the phone is totally brick, can anyone confirm it? Here we go
The phone came totally crazy and it has restart automatically, and went to the Fastboot mode. (i dont know if it was updating something, i had not using it). So, I've UNLOCKED it with the code that Huawei brings, till here everything is fine. The problem becames when I try to flash the CUST, CACHE, ABOOT, and the others that I think that are useless, it says
"FAILED (remote: Command not allowed)". But I can flash SYSTEM, RECOVERY, BOOT and USERDATA correctly. But that doesn't solve the problem of the LOOP RESTART, it show the Logo of Huawei and keeps restarting. I also tried 3 other stock roms, and the problem persists. Also tried putting the dload in SD with the UPDATE.app, and starting the phone with 3 buttons pressed and I have the error of "Error:update.app is a invalid package" and doens't work. (If i go to the Recovery it just stay for 1-2 seconds and automatically restart again). I don't think it could be the power button because it stays well in the Fastboot mode and also tried the CWM and works. I've been searching solutions for around 5 hours and didn't found any. I wish someone could help me, thanks in advance!
PD: I have the ADB Drivers updated.
live it

Problem with my Huawei Honor Holly 2 plus TIT AL00

So here is what happened, its simple i was trying to root it, then something bad for god knows what happened, the recovery failed or maybe corrupt so i cant boot into it, then the fastboot also failed so this option also gone, then it was stuck on a bootloop, so with the two options of fastboot and recovery already made corrupt, i read on some forum to use spflash to flash a fresh stock rom, but that also failed (god!!!!!!!!) so probably that made the whole system corrupt, i tried every possible combination out there on the various forums and videos but nothing, it doesnt respond, the one and only thing i get is, it vibrates when i plug in the charger and vibrates again after some time and this thing keeps on, please HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Help] Blackview BV5800 PRO SP Flash Tool "STATUS_DA_HASH_MISMATCH"

Hello! I posted on the official forum for Blackview but so far I haven't gotten a response. TL;DR, my phone, a Blackview BV5800 PRO, could not boot up (stuck on logo) and using recovery mode doesn't work. I get mounting issues when I try to factory reset, wiping the partition cache, and even mounting it (an option).
So my last resort was to attempt to re-flash the ROM using the provided ROM file by the OEM, which they did have on their forum. The first time around when I downloaded the ROM plus the SP Flash Tool, followed the instructions and all, it appears to be flashing just fine. As soon as it finished with the checkmark on screen, the phone is stuck in a black screen and Windows keeps detecting the device over and over, but nothing happens on the phone. From my research online, this is a feature of all MediaTek devices in an attempt to restore a factory ROM.
Now, when I try to flash again with the SP Flash Tool with the same ROM, I am getting a "STATUS_DA_HASH_MISMATCH" error. Or sometimes i get the "STATUS_BROM_CMD_SEND_DA_FAIL error. At this point, I tried every possible option within the tool itself as well as trying all combinations on the phone Power + Vol down/up/both then plugging it to my PC, nothing. It keeps showing the same error.
Frustrated with this, did I screw up something? Did the preloader corrupt during the first run? I don't know what to do at this point.
