Need help... My phone keeps disconnecting in preload mode (When I connect the phone without battery to PC to flash with SP tool). Problem started after I flashed once my phone via SP flash tool.
I have a canvas a1 AQ4501. Some days ago it just stopped working normally. When it turns on, I see the company logo with half screen turned yellow. Then it tries to restart but the same problem.
I have tried:
Using SP flash tools version 5.1524 but it goes into 2020 error while flashing, without battery. With battery phone is not detected.
Using twrp recovery to install cyanogenmod but it says partition had unexpected data after OTA update, something of this kind (did this using adb sideload)
The only thing that I can do with the phone is go into fastboot mode, recovery mode gets stuck on company logo. I can go to twrp recovery mode successfully.
I am using a windows 10 computer. Phone was on marshmallow when it last worked. I do not have an SD card. I have tried pressing both volume up and down with and without power button to flash using sp tool but phone is not detected bu sp flash tool in this case. I have tired meta mode (pressing volume up and power) here, phone is detected by sp flash tool but it goes into 2020 error BROM ERROR : S_BROM_CHKSUM16_MEM_RESULT_DIFF (2020).
Please help me as this phone is dear to me and has sentimental value.
Thanks for your time.
Bro give ur phone to MMX service center they will solve ur problem
Dear All,
I bought a Mi max 2 months ago, after using it some,i decided to change my rom.
What i did:
1)Unlock phone via mi
2)Usb debugger
3)TWRP
4)Supersu rooted
Everything was fine.
I downloaded a rom and flash it in fastboot mode and BUM! total darkness.
After some research , I managed to reach my phone via MiFlash.
Mi Flash now sees my phone as a port device Qualcomm....
I downloaded a correct rom.
So what is my problem !
In EDL mode,I start flashing, 2-3 seconds it flashes than it says `can not see port`(I downloaded all drivers,disable/able driver enfor...sth)
And phone turns in NULL mode, no connection any more from pc to phone.
If i disattached/attached battery and connect again to PC in EDL mode, i can reach it for a few seconds and than again losing connection.
I need my phone to keep connected to my pc untill i will finish flashing.
It is complicated, i am not even sure if it is possible or i damaged my motherboard.
What can i do???
Thanks in advance
I have a lenovo vibe k5 plus smartphone, which i erased accidentally, complete emmc erased. Now my phone won't start. It is neither booted into fastboot nor adb, not even recovery. When i plug it into my PC, red LED is on and it is automatically detected as Qualcomm HS-USB QDLoader 9008. I have tried qfil, Tool studio, QDloader, and even Miflash,but nothing worked.
Qfil says: QSahara error,
Tool studio: MPRG.mbn download failed,
QDLoader: send result,
Miflash: Reached end packet, can not receive hello packet.
if anyone can help me please tell me a proper way to recover/unbrick my phone Thanks in advance.

Click to expand...
Click to collapse
Perdonnaly I would suggest QFil :
- remove the battery
- put it back
- push volume + and - and plug your phone at the same time
- be careful to use qpst 2.7.430 (you can find it on other threads)
Sent from my Lenovo Vibe K5 Plus using XDA Labs
I have tried qfil of qpst 2.7.422, 2.7.430, 2.7.437 and 2.7.472 but nothing worked.
I tryed to get cwm on my LENOVO B and cwm don't working.
My phone restarts in a circle.
I can't go to download mode and my PC it detects him briefly with phone port-Mediatek preloader(COM4).
If i try run sp flash tool and i trying to download orginal soft, i ca't do this because it detect him briefly
Please help
