Dear members, this is my first post and the problem is very complicted, so please bear with the long post
Device details:
LeEco Le1s (x500)
MTK6795 chipset
3 GB + 32 GB
Background:
I downgraded my ROM from 19s to 14s with SP Flash tool and the phone booted normally. I went through the initial setup, unlocked Developer mode and USB debugging. Then I opened the adb toolkit on Win 7 x86 machine to unlock bootloader and install twrp custom recovery at single go (instead of letting phone rebot after bootloader unlock and then proceeding with recovery flashing).
Now phone went to soft brick, to overcome which I needed to flash userdata with sp flash tool (I have done this in past also following a tutorial, the same files were used this time). But flashing process resulted in BROM error and I was not successful.
So, I re-flashed the original 14s rom via SP flash tool to get the things back to working, but phone didn't boot properly and bootloop situation was still there. I again reflashed the same ROM and this timephone entered red light of death mode, and didn't boot up after flashing original rom.
Now, I again googled this problem and found that we need to format flash with bootloader. Here the problem complicated further.
As soon as I formatted the flash and the bootloader, laptop stopped detecting the phone via usb cable. Now I can't flash any rom using SP flash tool as the phone is not detectable.
I have reinstalled my windows 7 32 bit operating system and reinstalled all the drivers for MTK smartphone. I have another Le1s phone running on 19s version of EUI marshmallow with stock recovery and locked bootloader which is detecting fine without problems.
Please guide me how can I resolve the problem.
Also guide if the other phone can anyhow help in this matter in terms of software backup for SP flash tool (I couldn't find a way of backing stock rom using SP flash tools.
Problem summary:
1) Flash with bootloader formatted
2) Phone is not detectable on Windows 7 32 bit OS and latest SP flash tools
3) Red LED turns on when phone connected to charger or laptop via usb cable,nothing on LCD display
4) Can't reach bootloader or recovery either
Help will be really appreciated. You all know the value of data stored on smartphones.
Thanks in advance!!

15 days ago I migrated from android M to Android L cos fast battery draining, I flashed Android L stock rom using SP flash tool v5.1424.00. and everything worked fine till yesterday, my phone started crashing some apps so i restored it and my phone stuck in boot loop again (why again? cos before i got bootloop 4 month ago, that time i get rid of by flashing Android L stock rom "thanks to xda-developers members:good:")
so after restore my phone stuck in bootloop, so just like last time i did all steps to flash stock rom and it downloaded successsfully but bootloop not resolved. i did it again and again.:crying:
after that I used format all + download in SP flash tool (I think that big mistake I did) and after that Android One has full bricked, phone is not booting or not able to go to recovery mode or fastboot.:crying::crying:
not working anything pressing power button or Power+Volume but my pc detecting in device manager. I am able to flash in "download only" mode So I tried to flash stock ROM using SP Flash Tool and it downloaded successfully. But still not booting.
one more when i tried "firmware upgrade" in SP flash tool i got error "failed to get pmt info"
at last my device is bricked please please help me to unbrick it
Thanks in Advance
while flashing lollipop via sp tools it complete successfully, but after that my phone is not starting up not even charging but it is detected via sp tools and computer also. i used firmware upgrade while flashing. and in Memory test it shows "ERROR: NAND Flash was not detected!".
previously my camera was not opening and each apps are crashing so decide to flash stock rom.
now i have a bricked phone.. how to recover it need help
Hi everyone,
My canvas a1 (aq4501) was on September security patch (6.0.1) [unrooted but bootloader unlocked], but suddenly some Google Play services stopped working. So I switched off the phone but the problem was not fixed. Ultimately, I tried to clear cache & the wipe partition but it continuously showed up with the error ''failed to mount the recovery image". Now on opening the phone, it was stuck in a bootloop.
So, I tried to flash stock lollipop 5.1 rom by sp flash tool (5.152400- latest version) [I've earlier done this before as my rom got corrupted earlier] by download only mode but even after successfully flashing (ok done appeared), the phone's rom was not overwrited and it was still hanging on 6.0.1(MOB31E). So this time I tried to flash marshmallow 6.0 rom but again the problem remain unchanged (device was still at 6.0.1- MOB31E in recovery mode even if the flash was successful as shown up by SP flash tool).
So now I tried format+download only mode, again the flash was successful but this time not even the OEM logo (micromax logo) appeared and neither did the recovery mode. That means that my device got bricked. So I found this thread of http://forum.xda-developers.com/canvas-a1/help/micromax-android-one-bricked-unable-to-t2999760. and found that by firmware upgrade mode, we can get our phone back. But as shown in one of the comments of that thread, they got an error "failed to get pmt info", I got the same error too. So, I am helpless as I can't do anything. I've not tried stock KitKat rom yet and also ensure you that all my drivers are correct as SP flash tool is working flawlessly on my pc.
Please help me to fix this problem..........Is there any way to fix it using android one toolkit?????
Hey guys,
so this my problem:
I got the Mix 2 with the Chinese ROM. With the XiaoMiTool by Francesco Tescari I updated to the Global ROM V9.1.2.0 because I didn't want to wait to unlock the bootloader. This worked but I only had the choice to set China as my region. Since this was a common problem with updating the ROM without unlocking the phone I unlocked it and waited for 3 days to unlock.
Today I installed TWRP and installed the ROM xiaomi.eu_multi_MIMix2_7.11.16_v9-7.1. After this I was stuck with the Mi bootup logo. In TWRP I deleted cache, system, data. This worked EXCEPT for system. I thought updating TWRP to the newest version would help solve this issue. But since I'm new to this I didn't update it within TWRP but just installed the newer version via the commandfastboot flash recovery twrp.img. The result is that I can not get in recovery mode anymore. The only option is fastboot mode or the regular Mi logo endless boot.
What I tried so far: EDL flash method via adb/MiFlash but both don't work. The XiaoMiTool won't work too. The Mi PC Suite won't recognise the phone. When I use the edl.cmd the phone will go black for 2-3s and then return to fastboot.
I guess the problem at this point is that usb debugging is not turned on since TWRP installed the EU ROM and I could never get in it to enable the debug mode.
I couldn't find a solution to solve the boot up problem and can't seem to install/flash a new ROM at this point.
So what can I do? Do I need that special usb cable? Will the EDL points help me?
Maybe/Hopefully you can help me out.
EDIT:
When I turn on the phone it will directly go into fastboot mode. A normal start is not possible anymore?!...
EDIT 2:
I am now running the latest Global Rom this guide did it for me: en.miui. com/thread-1351514-1-1. html
Good to hear you got it up and running.

pls suggest me a way to get my recovered
Hey Bharath1705,
Have you tried fatory resetting? Or maybe reinstalling the stock rom? Usually reinstalling stock rom fixes bootloader because it reinstalls it. To install twrp you don't need download mode (also called EDL Mode, used mainly for unbricking the device when bootloader does not work), only fastboot. Follow the installation steps from here: https://twrp.me/lenovo/lenovoA6020.html to install TWRP. I advise to not use Download Mode, it is almost never required to install anything on the phone
