Hi, I am trying to unlock my phone but every time I try to connect the device in bootloader mode I get this error in the device manager.
This device cannot start. (Code 10)
A request for the USB BOS descriptor failed.
When I connect the phone normally, everything works fine, and the computer recognizes my phone. Only when I restart into bootloader mode does my computer not recognize the phone.
Does anyone have a solution to this?
I have downloaded all the drivers and htc sync and nothing worked so far.
Hello all,
I have a rooted Micromax A58 which was perfectly working. I did a full nandroid backup of it 2 days ago. On yesterday, I was moving some system app (google maps, play store etc) to SD with some software) so that I could increase the internal memory and install some other softwares. But, unfortunately, after that modification, the phone stopped working properly (it was stucking up when the BOLT logo was reached). So, I started it in recovery and do a wipe cache and factory reset. After that, the phone is always going to Factory Mode.
Then I tried to Flash the Stock ROM using Flash Tool but was unsuccessful multiple times. After the scatter file selected, when I clicked the 'Download' (or even firmware upgrade), all time time, the phone was disconnecting/reconnecting every now and then and nothing happened after (even though I already installed the Vcom and PdaNet driver in the PC). So, I had to quit. I am attaching herewith the logs of the Flash Tool lastly tried.
Now, when I am starting the phone power button, nothing is happening.. NOTHING but black screen...
I am a bit worried.. your help very much appreciated. Please let me know for any information needed. Thanks.
'No com port detected' error
I tried another time and the problem still there.. When in SP Flash Tool, I select scatter file, click 'Download' and connect the phone to PC, the process doesn't progress further. So, I have to finally click 'Stop' to quit. In the logs, it shows--
"No com port detected.."
Attaching the trace logs file herewith.
Please advice how to resolve the issue.. I am totally stuck now. Thanks.

Hello Kapil,
Thanks for the response. Yesterday I tried with separate laptop, but the same problem was there. Today, I tried with the different USB port.. but didn't help.
It seems that the driver can not recognize the device and when I connect the phone, it is just in a loop of disconnecting/re-connecting. Please advice further. Thanks.
Only option now seems is Service Centre.
The guys are pretty dumb. I've tested samsung motorola etc.....they don't even know what root is.
Maybe they'll be unable to identify what you tried to do.
You can give any reason for it not functioning.
Good luck.

Thank you Kapil for the advice. As Micromax service centre is not having a good reputation regarding these, so I would go for that option as the last resort.
Before that, can I please ask the other members for giving further advice if there is any option to try with.. Thanks for your help.

I tried the above multiple times but everytime same error as above.
When tried to connect the phone (without battery) it is disconnect/reconnect in an endless loop.
When try to connect with battery, the disconnect/reconnect loop is gone (i.e.-stable) but sometime it can not identity phone ('Unknown Device').
Also tried to press volume down button along with battery inside, but showing 'Unknown Device' and Flash tool getting hanged.
I used the Stock Rom downloaded from xda site for my phone detailed below---
Android 4.2.2
Model Micromax A58
BaseBand version- MOLY.WR8.W1315.MD.WG.MP.V1.P11 2013/09/04 15:51
Kernel 3.4.5 [email protected] #1

I also have the good nandroid backup (if it could be of any use) but phone is dead now. Confused how to go forward. Please help.

In the meanwhile, when trying to resolve the issue, I tried the following steps and after that, I lastly managed to 'download' the Stock ROM successfully in my phone (using the Windows XP OS)--
1) As I was always getting the SP Flash Tool error 4032 for last couple of days and which was clearly describing 'please check your load matches your target which is to be downloaded', so was investigating the root cause in details. Upon searching in the internet, I downloaded multiple version of Stock ROMs for my Micromax A58 model from different sources to give a try. When trying to 'Download' (in SP Flash Tool), the 'T_09' ROM (link given by 'alanvmathew') in the below mentioned URL worked for me.
http://forum.xda-developers.com/showthread.php?t=2610046&page=2
It is to be noted from the link that Micromax A58 model have 2 different Stock ROMs (i.e.- 'T_07' and 'T_09') which info I was missing all the time.
2) After identifying the scatter file in the SP Flash Tool and clicking the 'Download' option, I inserted battery in the phone and pressing the 'Power + Volume down' button, connected the device into the PC USB. Upon connected, the 'DA USB VCOM PORT' driver automatically installed and the 'Download' started and flashing of ROM went smooth. Finally, it ended up with green 'Download OK' message. Also attaching the snapshots herewith.
Will check the mobile and its performance further and revert back accordingly.
Hello i have what appears to be a soft bricked samsung galaxy grand prime after i rooted it. It boots up and goes past the samsung logo but stops/freeze at the carries logo ( metro pcs ) I can get IT into download mode but when i try to plug it into the PC via USB it just doesnt recognize it. It says ' USB DEVICE NOT RECOGNIZED' I tried instaling the drivers and all but nothing seems to do the trick. UNKNOWN USB DEVICE ( DEVICE DESCRIPTOR REQUEST FAILED) is all i get. My only problem here is getting the phone to plug into the pc. The rest ( restore to stock rom with odin) i can do. PLEASE HELP ANYONE
My vivo Y55L was stuck in a boot loop and did not go ahead of the vivo screen.
I tried flashing the stock ROM through QFIL but it gave me a EDL Firehouse error and the flash was unsuccessful. I disconnected the phone to reconnect but to my misery the phone does not connect to QFIL anymore. When i press the power up and down button and connect the USB the computer gave me an error USB device not recognised and may have malfunctioned. if I power up the phone now it doesn't start and goes back into the bootloop for 2-3 times before switching off. I have tried reconnecting the USB and reinstalling ADB drivers and Qualcomm drivers. But still the same error, Device receptor not recognized and USB device not recognized may have malfunctioned. Any solutions will be appreciated
