Device doesn't connect to PC - Xiaomi Redmi 3s Questions & Answers

Hi everyone,
I see this is an issue that is being extensively talked about but after trying many solutions proposed by many users I am still out of luck, there is no way I can connect my device to a PC. USB debugging is on, USB config is set to MTP, USB drivers are installed.... but still, no luck, won't connect.
This means that I cannot even unlock the bootloader the official way since the phone goes undetected. I am on MIUI 7 Global Stable MALCNDE and I cannot upgrade to MIUI 8.... because if I reboot to stock recovery from Updater, the phone will reboot to a fancy diagram advising me to plug in a USB cable. Also, if I try to reboot to recovery by holding power/vol +, the phone boots in some terrifying recovery in chinese, with only four options that are translated. One of them is recovery and if I click on it.... I get that fancy looking diagram.
So please, any advice on this would be much appreciated.
Thanks.

Did you tried the official MiFlash app? http://api.bbs.miui.com/url/MiFlash

[Q] PC died when upgrading GT540

Like topic says. Was doin' it via LG PC Suite. Now it's only LG logo on my phone. Any ideas what should I do?
Are you planning to install custom ROMs on your phone?
If so, check this out:
http://forum.xda-developers.com/showpost.php?p=16783348&postcount=1
Instead of doing this:
Prepare the phone by enabling USB Debugging by going to Settings>Applications>Development>Enable USB Debugging and connect the phone to the computer via USB cable and let Windows install any drivers it needs.

Do this instead:
Hold down volume down and plug in the USB cable and 'download mode' should come up on the screen. Let windows install any drivers it needs. Then launch software update.

Hope it fixes your problem and device
Same thing happened to me, bricked my device, took it to phone shop they flashed the board and it worked again, think i could have just entered download mode and reinstalled but, i was a noob then still am tbh
Just put your phone into download mode.
Flash fastboot.
Then reflash your ROM!!
ALL DONE XD
Any
You can flash any ROM you want via fastboot and any failed attempts won't completely brick your phone.

Nexus 7 Fastboot freeze on USB connection

I never thought I'd have to go as far as create a thread pleading for help, but after a lot of Google searching I still cannot find someone with the same problem.
I will explain:
I am trying to use fastboot, which I (don't think) I've any problems with in the past.
I can issue commands in normal use via adb from my PC fine.
I can adb reboot bootloader ok, and can get into the bootloader any other way just fine.
I can use the volume keys to navigate the options in the bootloader just fine.
The problem comes with I connect the USB to my PC whilst in fastboot.
Windows fails to recognise the device, and says it may have malfunctioned.
It won't allow me to reinstall the drivers successfully it seems, and seems to have a problem with the USB Host Controller too.
Fastboot immediately freezes, and I'm unable to even navigate using the volume keys, let alone issue commands from my PC.
My question then is twofold:
1. Is there likely to be a problem with the USB port on my device, or some sort of bootloader corruption?
2. Is it possible to return to stock Android without using fastboot?
Finally, I would like to stress that I've seen plenty of similar looking threads, but it seemed that the posters of those threads merely had problems getting in to the bootloader or recovery.
I haven't got that problem, the problem only arises when a USB is connected to the PC, the tablet becomes unresponsive only in bootloader mode.
If anyone has any advice to offer at all, I'd greatly appreciate it.
Additionally, if the problem is solved, I will post a detailed set of instructions in case anybody else should encounter a similar problem in the future.
__________________________________________________________
Update for anyone who happens to read this in the future:
[This guide](http://forums.androidcentral.com/ne...3923-guide-nexus-4-factory-image-restore.html) has a useful FAQ at the bottom which helped a little.
I think I managed to determine the problem was likely a duff usb connection, either on my Nexus or on my computer.
I was able to just about hobble through by keeping the cable in the same place.
In case it wasn't just this, this is what I did:
1. Flashed TWRP recovery from their app.
Went into bootloader and failed to do anything
2. Flashed CWM recovery.
Managed to be recognised in fastboot.
I still had problems with my Nexus 'malfunctioning' -- possible the USB.
I updated the drivers using the ones from [this thread](http://forum.xda-developers.com/showthread.php?t=2588979).
3. Flashed a new bootloader image immediately (there were rumours that a dodgy version had been released accidentally). [This](http://www.androidfilehost.com/?fid=23060877489996594) is the one I used.
Then I managed to get the stock ROM flashed, and the bootloader locked up again.
Fastboot freezes whenever USB plugged in
I'm having a problem with this step...
1. When booting to fastboot with any sort of USB plugged in, your buttons on the side may not respond. In this case, pull the cable and hold down power + Vol Down until it reboots. The buttons should now respond and you can plug USB back in if you wish.
the problem is that whenever the USB cable is plugged in, the buttons don't navigate through the options.
however, whenever the usb is NOT plugged in (and rebooted bootloader) the button work just fine.
I don't have a recovery currently installed.
The issue is not with drivers on the computer,
happens while usb plugged in both windows and linux or simply just plugged into a wall outlet to charge and with different USB cables.
I need to load fastboot but i'm having this issue. Is the device bricked without hope?
any help would be appreciated.

Bricked Jiayu S3 Advanced help!

Yesterday i flashed my Jiayu S3 to lolipop (i tought) and i just bricked my phone!
After reboot it was just dead.. when i plug into pc with USB i hear the connect sound and after 2 seconds the disconnect sound. This keeps on going until i pull the USB plug.

I tried with or without battery, but without it does nothing at all.. i tried holding Vol+ or - or both or with power button, but nothing.
Read some threads about unbrick and install correct usb driver for jiayu s3, but all the options they came with does not work on my device!
I'm a little despered now and don't know what to do.. i get the feeling that my 2 weeks old phone is dead? :'(

Just flash it again, but this time with "Firmware upgrade " in SP Flashtool instead of "Download". Change from KK to LL needs reepartitioning, so firmware upgrade.
The reason why you don´t "see" the S3 any longer on the pc is, that the USB storage mode from KK, which is driverless for windows, don´t work right now on LL.
Once flashed to LL you will need to install a driver, for windows to connect to the S3.
@ Dior DNA:
No i can't. Phone does nothing with the buttons. Only diference if i hold Vol - then time from connect sound and disconnect sound is a little longer.. about 10 seconds. But still nothing happens.
@1testi:
Flashtools can't see my phone. I tried it a hundred times. With battery, without battery, with Vol - and with Vol +.
When i connect the USB cable i hear the connect sound and after 2 a 3 seconds i hear disconnect sound. This goes on and on until i pull the USB cable out. In devicemanager i see a refresh going on, but nothing pops up.
I'm realy despered on what to do now?

Why the SP Flashtool isn´t working any longer? You didn´t deinstalled the driver, did you? Just try to flash again with "Firmware Upgrade".
I don´t know a way to reinstall the driver in windows without the preloader. The only thing you can do, as far as i know, is to use a linux
pc to flash again. Linux don´t need a driver for SPF, only some rules.

Booting into recovery or flashtool I meant regardless of pc and/or spflashtool.
If I recall correctly:
hold volup and power boots recovery
hold voldn and power boots flashtool
If you can boot recovery then which one is it? Maybe you can restore something or manually flash preloader bin from there.
After the flash i reboot and then the connect and disconnect sound appears. So i tried differend things, but could not connect. I wanted to flash again, but flashtool did not reconice the phone and nothing in DeviceManager. That's why i thought to remove the driver and try to re-install it. But that did not help..
Holding Vol - or + button with power button or both Vol buttons with power button does nothing.. i tried to hold all combinations at least 30 seconds, but nothing at all.
I have no Linux pc or any knowhow to make a Linux pc.. or a pc to install Linux on..
One last thing you can try: remove the battery, wait a little, insert the battery again. Hold vol+ key, keep holding it and press power
button, while still holding the vol+. If you don´t see anything happening then you bricked the phone.
You will need help from a professional or at least from someone with a linux machine, sorry.
I'll try that.
You have any idea what could have caused the brick?
As i wrote above, moving from KK to LL with wrong parameter "Download" in SPF.
....and a not working recovery.
You should try this method :
darmowyinternet.net/forum/temat-poradnik-jak-uruchomic-uceglony-telefon-po-wgraniu-zlego-romu-test-point_383
unfortunately you have to translate before
Ok i tried that site with google translate and i could a little make up what they are saying.
But that is a very drastically operation, and i would like to give it some other tries before dismantling my phone.
So i googled and googled.. came here: http://forum.xda-developers.com/showthread.php?t=889128
Had enough electronics lying around from my former 27mc hobby, so searched for the right resistors,
cut up a micro usb cable and give it a try... well.. nothing! Tried for about an hour and gave up.
Then i googled on Unbrick Jigs, but for what i read they are only for Samsung phones, so i gues the trick
with the resistors were also?
So googling again... came here: http://forum.xda-developers.com/showthread.php?t=2454004
Reading the tread and the comments, someone mentioned a download for "Mediatek Driver Auto Installer".
Downloaded that and installed the drivers. Plugged in my phone and... whoohoo!! Something is happening! :silly:
My devicemanager saw an "Alcatel single RNDIS interface". I unplugged and plugged my phone a few times to
be sure it was my phone. Sooo... one step further! :good:
Then i googled on this device.. came up with all sorts of network devices, not helpfull. Then googled on Jiayu with
this device. Came up with this tread: https://www.china-devices.com/topic...vcomm-drivers-onto-your-pc-win-7vistaxp-only/
It's a tread about bricked Jiayu G3 devices, but i thought, 'What the heck, lets give it a try!'.
I downloaded the "MTK Megapack - All Tools Here!" and unpacked. Wend back to device manager and manually updated the driver
of the Alcatel device. Show all devices - browse - wend to Megapack map and there were MTK drivers for the 65xx device.
And yess.. when i plug in my phone there's the device: " MTK USB Port (COM7) "
SP Flashtools sees my phone again! :good:
Tried to flash a stock preloader, but got an error: "BROM ERROR : S_FT_ENABLE_DRAM_FAIL (4032) – [EMI] Enable DRAM failed!"
But for now that's a problem for tomorrow.. it's almost 2:30 and i have to got some sleep!
(sorry for the misspellings or telling things not clear, i'm tired and english is not my main language)
Grats!
You can google the error. This leds you in the right direction.
It's alive!!!!!! :laugh::silly::victory:
Because the kitkat stockrom i downloaded gave me the same error over and over i searched for something else.
So i downloaded TF Extreme lolipop 5.1 this morning and give it a try. And all went well. I pulled the usb plug and
pushed power button.. only vibration but nothing. Then pulled the battery and after few seconds put it back in
and try power again. Only 1 vibration.. then tried Vol + and - combinations but nothing. (dammn!)
Then plug the usb in and i saw the battery icon.. it was total empty! (because of a week trying).
So now it's charging and i hope it starts, can't wait!!
Thanx all for the effort in helping me out! :good:
Edit: Ok, so i could not wait and hit power! It shows green screen with Jiayu S3 logo and text "New Load". So i guess it's prepairing for first startup!
my s3 basic is not charging when on.. also when connected to pc thru usb, ipc shows device malfunctioning ,and there is no indication on phone..I try to connect to sp flash tool also no success..same error"usb device not recognized pops up every 2s.everything else is fine..Any method to upgrade to 5.1 now on official kk
Kinda need help, happened something similar
It happened something similar to me.
I flashed the whole ROM, bootloader included, I was very sure that my model, Jiayu S3 3GB ROM + 32GB RAM, was the correct, but still bricked my phone.
There's no problem at all when I plug it into my PC, I installed the lastest MTK drivers on windows 10, having to disable the signature enforcement.
The problem comes when I start flashing. I only mark the bootloader, then I press "Download" (on the lastest version of SP Flash Tools), and plug the phone, with the battery in it (I've tried without battery, pressing all possible combinations and does nothing), when I plug it in with the battery and pressing no buttons, the driver is detected as MTK USB Port. That's a good thing I guess. But It does not pass from the red bar, and gives me the known error "Enable DRAM Failed".
I've tried to google any possible solutions, reinstalling other version of the MTK drivers, on different versions of Windows, with other versions of official ROMs, and the result is always the same.
The only thing that's left to try is flashing it with an Ubuntu machine, which is something I do not expertise to be honest, but I'm gonna gather some info and try to do it.
However, if someone has any idea of what I might be doing wrong (excluding the part when I flashed the bootloader, I'll never do it again), I would be really grateful for any kind of help.
Thank you!

Oeps it might be the same problem with the 32GB version as I have.
See http://forum.xda-developers.com/showpost.php?p=68036678&postcount=295
I am waiting for a stock ROM backup.
I have learned to never flash the original preloader again.

You're right, with the 32GB rom version (which is still unavaliable for public use) it worked! I still got it here, so anyone feel free to ask me the link too.

[Q] Is there a any way to get ADB working on a TA-1025?

Hi, Just got the amazon ads Nokia TA-1025, I'm trying to get ADB working but even if phone detect the USB connection it will never ask for grant permission for PC thru ADB, deleveloper options is active as well as USB debug, tried using universal ADB drivers, included drivers and nokia 3 drivers with no luck, what I want to do is try to flash TA-1021 software or at least get into fastboot, thank you in advance for any advise!

For fastboot
1. Switch of your device
2. Connect your charger either via power or computer, your choice
3. Don't start your device just let it show that the phone is charging in power off mode
4. When you saw the bettery animation of power off charging, press and hold power button+volume plus button together and release only power button when you see android boot logo
5. Keep holding your volume plus button until you see recovery menu
6. In recovery menu you will find reboot to bootloader, select the option and hit power button to get into bootloader
7. Now you can install Mena firmware from Rom thread post of the nokia 6.
Enjoy
Hit thanks button if you find this helpful
Happy flashing
These have locked bootloaders. You are going to brick your phone. Geesh man. Read more before you try stuff like this .

no OS, no recovery, edl not working...

no OS, no recovery, edl not working...
hey
i'm new here
so hello everyone
i write this post because i have no idea what can i do else....
i try every method i found on xda (without dissamble) and my axon 7 still have no os...
long story short
some time ago i flash lineage 14.1 using Axon7_EDL_Tool
everything was ok
but one day lineage updater tell me there is update to lineage os 15,1
but you have to use twrp
so i download update
put it to sd card
reboot to twrp
Wipe system,data and cache
everything like i read instruction
then i flash lineage 15.1 in twrp
but it stop - saying error 7
i did not uprade TWRP - maybe it is a problem....
now i have no os, no twrp
and axon stop on "your device will boot in 5 second"
bootloader unlocked
usb debbuging on
i have win10 64b, win7 32b, win7 64b
I installed drivers for axon 7,
i bought deep flash cable
nothing helps.....
what happens if you connect the charger to your phone while its off? not to pc, to wall charger
also, does the LED flashes once and then turns off while trying to access EDL? or does it stays on all the time? or maybe never lights up at all?
Always, if you update ROM to higher Android version, then you have to check TWRP version. 1st attempt - try to install TWRP.
I think error 7 means that you didn't flash the Oreo bootstack. If you can get into bootloader/fastboot mode then you can follow this to flash TWRP. Or give this a try, I haven't tried it myself though.
you need los15 bootstack lol.Go to los15 thread,download universal bootstack v2,flash in twrp,then flash rom (oreo rom)
Keep pressing power , volume + and volume - and this will force into EDL.
Then flash universal orea bootloader then recovery. Then u should be good to go
I can't flash anything...windows can't see my AXON7 - this is main problem...
I tried the tools you wrote but they can't connect my phone
I don't know what else can I do to communicate between phone and computer
Change the cable.
O tried 4 USB and 2 deep flash...
Pressing power , volume + and volume - will turn the led notification red right?
Then you connect the phone to the PC.
You have to check the device manager, what you see there?
Can you get into FTM?
Vol down and power button.
Try installing Zadig drivers and see if that helps
In the device manager in windows you need to see
Qualcomm HS-USB QDLoader 9008
If all drivers are setup correctly
Try installing twrp via fastboot.
Hope this helps
Nothhhing appears im device manager...
Still nothing..
what happened when you press both volume button and button together? for Oreo it will just show black screen or it will show FTM mode on the screen if you on older bootloader. Keep pressing the 3 button until it show black screen then plug in to your computer... make sure you windows firewall and security is all turn off.
Can you check on Windows' Device Manager if the Axon 7 is recognised as DFU, after you try to enter EDL mode? (Also, usually, the notification light is red and stays on).
Similar situation
Hi,
I'm in a similar situation. I'm guessing my recovery was corrupted. I even disassembled the unit to try to get it into EDL mode, which may be working but the device is just not recognized by my computer, though it does charge. My next step is to try replacing the usb connector, or just move on.
Good luck!
Ed
