[Q] Several problems after tried downgrade - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi there,
I have some problems after I tried to downgrade my Sony Xperia Z3C from Android 5.0.2 to 4.4.4.
I hope you can help me. I searched some hours now and tried to fix it myself, but nothing helped.
Now the problem: The phone does not boot. I get following message: "the software update failed make sure that your phone is connected to the computer and try again".
So far so bad. Then I tried to put the downloaded firmware via Flashtools on the device. But the problem is, that my device disconnects every minute and after some seconds it connects again and so on. So I do not have a constant connection to load the firmware on the phone. In another thread I have read, that maybe the drivers could be the problem, but I installed the Flashmode drivers and Fastboot drivers.
Another problem is, that the hard-reset does not work. Not with vol+ and power and not with the yellow button next sim-card.
I really need help. Thank you and Kind Regards.

Is the USB port in your PC clean? I once had USB connection issues, and turned out that the USB port was all clogged up with dust. :silly:
Also, try unplugging all other non-essential USB devices before flashing and turn off anti-virus because you never know...

[Q] Unknown device - Samsung Galaxy S

Hello,
My Samsung Galaxy S is listed as Unknown Device.
It started after an update to 2.2 via Kies and i did that with the regedit exploration. That was the 2.2 beta and then i updated it again with the official release this time also with the regedit exploit. I have formated the internal SD (i cant dismount it cause im on froyo i guess? atleast there is no option about it). Factory reset and so on.
Reinstalled kies 5 times, installed USB drivers again and again. I have tried it on different platforms with both XP (32-bit), Vista (32-bit) and Slackware Linux (32-bit). The computors just cant find drivers for the device.
I have tried all the different usb options in the phone settings nothing happends. I think i have tried everything that can be found here and on google...
The phone is Rooted and im now on PDA: I9000XWJP6, PHONE: I9000XXJPM, CSC: I9000XEEJP4.
Build Info: 2010. 10.
I believe the main thing here is that i dont even get the MTP application in the phone to recognize that a USB connection have been initialized. Nothing happend in the phone when i connect the USB no MTP screen or anything, just chargeing. I have tried 2 diffrent usb cords both that worked before so its not that.. The computor just says unknown device and Kies dont notice anything at all.
I have tried installing another firmware with Odin in Download mode and stil unknown device.
So i believe the phone have, in some way lost its internal usb drivers? I have also noticed that the battery "100% charged" icon does not disapear after i disconnect the usb or the charger. Also sometimes the icon continues to charge after i disconnect. Sometimes when i turn the phone of it starts by itself after like 2 min.
Anyways! What i was wondering is if there is a way to install an official firmware via update.zip volume-up+home+power?
When i try to install a customized rom with update.zip it says:
E:signature verification failed Installation aborted.
Cause of 3e bootloader? But i think its best to maby have a good stable firmware before i go customized?
So any help would be appreciated!!! heeeeeeeelp.....
Try installing theses drivers x64 x86 depending on what operating system you're on.
If that doesn't work try going into download mode and connect with odin. With the recovery problem you need to flash 2e recovery
You can also try and download and flash the latest version firmware to your phone and see if that helps.
Good luck and tell me how it goes

Hi m8!
Thx for the reply!
I have allready tried installing those drivers doesnt work for me.
I have tried Download mode with Odin to, it still says Unknown Device in Windows (i have Vista 32-bits, but tried it on XP and Linux to).
So anything that has to do with a USB-connection seems impossible at the moment...
The phone dont start the MTP application at all and windows dont install the drivers, it just says unknown device when trying to install.
I just unistalled Kies and removed everything from regedit with "kies" in it and then rebooted and downloaded a new fresh Kies file. Installed it and rebooted again while i wiped the phone, formated the SD and did a factory reset.. still "Unknown Device" :[
The problem seems to be the software in the phone.. so my question is: Is there is anyway to update or flash the firmware in the phone without any USB connection?
Is there maby any way to get 2e recovery mode without usb connection?

There is an app in the Android Development section here that allows you to flash a kernel within Android. Never tried it myself but I believe it is now stable and you could use it to flash CF-Root internally
EDIT: Here you go...

Have you tried recovery mode? Big yellow triangle with Android man holding shovel. Then connect to PC with Kies running and click on firmware update button.
Thx man!
But it seems that i dont have root access anymore, so cant use that app either :/ i think im a hopeless case.. :[

Yes man.. i get the same thing with the Yellow friend that says "Do not turn of target!!!"..
"One of the USB devices attached to this computor has malfunctioned. And Windows does not recognize it."
and also
"Unknown Device Installed
The software for this device has been successfully installed.
Unknown device - - Ready to use"
Are you connecting through a hub or direct to the back port of the PC. A hub will cause problems. If direct then try this.. Plug in and wait till you get the unrecognised device info. go into device manager, identify the device it will either say Samsung or unknown device. right click and remove device say yes if it asks if you want to delete the driver. now restart the pc after unplugging the usb then after it has fully restarted and connected to the net plug it back in again. Hopefully it will look on the net for the driver and install the correct one.

Yep tried that to.. i have even tried it on 3 diffrent computers 2 of them in all usb ports.. and everything els works that was connected in those ports.
I dont think its the software in the computer that is the problem.. :/
I believe there is some internal (in the phone) usb firmware problem, if thats possible?
i have exactly the same problem my usb by giving uknown device (i used it at 3 computer with kies software) it seems usb not working anywhere.
I believe our only solution is to find a way to install e2 recovery via the phone.
I have this problem also.
My SGS is rooted.
I tried everything. Googled many hour.
I din't know what more to do.
I have "Android system recovery <2e>" Is this an advantage?
I turned the phone in to my provider. this message is what i got from the repairservice.
Repair Details: The phone's charge connector is moisture/water -damaged, can not be repaired. returned without action.
WTF?!! i have been really careful with the phone. The only thing i can think of is that it has been really cold where i live (Sweden) and i had it in my pocket.. but i mean cmon! it goto withstand that!
I guess i have to wait for samsung to make it possible to update firmware via Wifi.

With Recovery 2e i think it can be possible to update your phones firmware with the update.zip file but i think you need to have your phone rooted.

All makes of Smartphone seem to suffer from, condensation problem .
Or at least thats what the service centres

I think so. I have my phone rooted and also ROM Flash Manager installed. The issue now is to find an european stock image to flash compatible with ROM Flash Manager
I looked for the stock firmware image (my phone has JF3) but can't find where.
Anyone?
I don't want to flash a cooked image just in case I have to ship the phone to the repair service.
Hello, I have exactly the same problem.
My SGS is unrooted, due to warranty, and alway keep it with maximum care (it is not a free phone...).
Symptoms are the same:
-It started after an update to 2.2 via Kies
-Absolutely unrecognized by windows (xp32 and win764) anymore
-battery "100% charged" icon does not disappear after i disconnect the usb or the charger
-turning the phone off it starts by itself after like 2 min.
More: incredible but sometimes when connected to car charger, I have the message "usb connected".
Already tried all possible (unrooted) tricks.
I believe usb internal drivers (if any) are corrupted (maybe by moisture?), how to reinstall them?
Maybe usb connector damaged; I have moved a little bit with a scrwdrvr the usb connector plate and clean with air and a thin blade but no result.
I will bring to service, as warranty is still valid, but surely they will discard me (I am optimist)
If there is any solution, please post it.
Hello,
Same here, can't connect phone to pc, mtp dont start on phone after connect it on pc !
Anyone know how flashback stock rom if its possible ?
Hi someone have a stock firmware for flash it in to recovery ?
I think i will try send the phone to samsung after reflashing for see what the guys from samsupport says about this !
Yes, if a part of firmware has been corrupted (with usb info for pc recognition) maybe the solution is to reinstall entire rom.
How to find a stock rom?
How to reinstall rom from SD card in a non rooted phone with no usb connection?

[Q] Phone semi bricked and unknown device in download mode

Hey all,
I've got a problem related to my Micro USB port (at least I think it is).
[Long story]
I've got a very annoying issue right now. Today I flashed Team ICSSGS RC4.1. Later when I connected my Galaxy S to my PC with the usb cable, no recharging icon appeared and my pc did not react to the connection at all.
Thinking it was a bug in RC4.1 (as OneCosmic RC 2.3 had the mass storage issue) I searched the ICSSGS thread, but not a single issue about mass storage mode was posted. So I flashed Devil kernel, hoping to fix it, but it didn't. Reflashed RC4.1, but problem still persisted.
I went radical and recovered a nandroid backup in CWM of ICSSGS RC3.0 (the one is was running earlier today), but somehow the recovery failed and left me with a semi-bricked phone. (Actually the 2nd time in a row when recovery semi-bricked my phone.)
Only download mode works. Recovery and normal boot bootloop.
[/Long story]
In short:
When connecting to PC to flash with Odin:
-At first the PC did not even notice the phone being connected through USB. Nothing happens.
-After blowing in the contacts of the Micro USB port, PC recognizes connection, but gives "Unknown device" error upon connecting. Reinstalling Samsung drivers does not work at all. Tested on laptop and home PC.
-Somehow I always have to blow into the Micro USB port to create contact and to get the PC to recognize a connection. But that's about it. "Unknown device" every time.
-When I plug in wall charger, the big battery icon appears, but stays grey all the time and after half a minute the phone boots, starting the bootloop.
Could it be that my Micro USB port is broken?
Any solution for this?
Thanks in advance!
I feel so stupid for recovering that nandroid backup. Otherwise my phone would still be working...
you will need the nexus drivers for your comp found here : w w w.multiupload.co.uk/BUCFT8M42 as your samsung drivers are no use now.
Thanks for your advice: Going to test it right away.
Unfortunately your link does not work for me.
I had the same problem but replacing the cable solved it.
Sorry for the duff link http://www.multiupload.co.uk/BUCFT8M42N

Tested this morning with someone else's cable, still the same issue.
Tried the Nexus driver, but still nothing. Also having troubles again to let the usb connection register. It connected after cleaning it, but now it does not seem to connect at all.
Could it be that the phone is completely busted and therefor breaks usb connection?
Haven't heard such a story yet, but is it possible?
I've got it sorted out.
Since it might be helpful for others that are searching for a solution:
1. I cleaned out my Micro-USB port using micro interdental brushes and a few drops of isopropyl alcohol. It also doesn't hurt to clean the contacts of your USB cable, just to be sure.
2. Connected the phone to my PC. This time my pc recognized it as a serial gadget.
3. Disconnected the phone and installed Nexus S driver (because of ICS rom on my Galaxy S)
Next connection my device was automatically recognized as an android phone.
Odin saw my phone as well and I could flash again!
My phone is back on Team ICSSGS RC4.2.
Thanks everyone for helping!
Same Issue cant fix
Hey guys im glad to see others are having the same issue but i cant seem to fix mine.
Assume im an idiot and ive missed something out but ill explain my situation....
Galaxy i9000 - windows 7 32bit - put ics on it a few weeks back following a guide on youtube (had never used odin or anything like that before) got it working but now have no usb comm options in the ics settings. now when i plug the usb (when it does detect at all) it says driver havent worked - device manager shows unknown device - i try update the driver and it says the best driver is already installed.
Im completely stuck and want to revert back to gingerbread so i can use my usb functions again. If i can get odin to see my phone again ill be relieved.
Any ideas?
Cheers guys! Seán.

Probably a hardware problem then....
I have had the same problem for a few weeks now. It started to fail occasionally and right now the usb won't work unless you reboot the phone. If i'm running out of battery, i must connect the charger and reboot for the phone to charge. And when the phone is charged, if I unplug the charger, the phone thinks it's still connected.... that is until you reboot again. It's a pain in the ass because also the phone wont go to deep sleep (ab8500 charger attached wakelock is keeping it awake at all times).
I was waiting for mi carrier (Movistar, Argentina) to update to Jelly Bean so i wouldn't need to downgrade (as i read some people experience CSC problems when downgrading) but I'm starting to grow impatient...
Same problem dude..

[Q] USB not functioning - intermittent ADB

Hi guys, hoping someone can help ?
As you see from the title, my HTC One fails to connect to the computer, Here's what ive done to try and remedie the problem.
Removed and clean installed latest HTC Sync and drivers
removed SDK and ADB, updated
rebooted phone
switched on and off
tried several roms
tried 3 different usb cables
tried 5 different usb ports
tried 2 different PC's
My phone sounds like it tries to connect to the pc - with the typical windows noise, then disconnects almost immediaetly, then reconnects then just keeps doing that, my pc comes up with installing drivers, then fails to instal drivers, saying phone not connected, once ive tried this once the phone need to be rebooted before it will attemp to connect to the pc again ---- but fails again
software wise the phone runs perfectly , other than the usb connection problem and charge problem with pc.
The phone charges first time, every time with all my usb cables and htc chargers
im trying to downgrade or reflash hboot 1.55000, just incase this has somehow went corrupt on the usb commands side, but without adb ect it seems almost impossible,
have any of you guys experienced anything like this or could offer solid ideas on how to re-flash hboot from the file located on my phone ???
all help appreciated
running ardh 13.4/22.0, hboot 1.55, cid = supercid, unlocked, s-off
I would simply go back to stock and return via shop in uk - to see if i could get a replacement, but getting there seems impossible - if i can simply get the pc usb problem sorted - all will be fine

Are the chargers working fine? or are they giving you intermittent charge/no-charge cycles as well? in which case it could be your USB socket is damaged or dirty, try cleaning it with a compressed air tank (or whatever it's called )
Are you also facing the problem in bootloader mode (ie fastboot)?
hmm, will give the usb socket on my phone a clean. Im charging completley fine with chargers and usb cables from mains, when i install htc sync(latest) it installs no problems, then i plug phone into pc, the usb connected appears on phone and then disappears almost imediaetly, the pc sees ive plugged something in and straight away tries to instal drivers - but then comes up with drivers were no installed correctly, also then the phone fails to charge from pc, if i reboot phone - and plug in it will run through the same install cycle again , as described above., basically all drivers fail to install when i plug phone in, its like the phone connects then instantly disconnects.
I ll clean port and post back, could make a difference if a pin has a high resistance contact , thx for info will give it a go

HELP: Sony Xperia Z3 Compact Unknown USB Device (Device Descriptor Request Failed)

HI, I need help fixing my Z3 Compact (D5803).
-My phone had Android 4.4.4, had Root and had firmware 23.4.A.1.200 I believe. (some pre-rooted firmware)
-I flashed that firmware onto my phone a long time ago and its been running great ever since.
-Today I decided to try more flashing, I rushed it and accidentally flashed firmware for the Z3, not Z3 Compact, plus I forgot to turn on USB Debugging!!!!
-It pretty much failed flashing, tried to turn on my phone and I get the update failed screen.
-I researched it, looked into repairing it through PC Companion, but decided to try flashing again and still not seeing that I had the wrong firmware.
-It seemed to have flashed some of the way but had errors and stopped flashing, I tried turning on my phone but now I get nothing.
-No LED, no vibration, no Charge LED, no Update failed screen, no Sony logo, no nothing.
-The only thing I get is when I plug USB into my PC then into phone, it takes 10 seconds, then I get sound on PC and a notification saying (Unknown USB Device (Device Descriptor Request Failed) but still no LED light on my phone or vibration.
-I tried uninstalling the driver, I tried different button reset ideas, even tried the little yellow button next to the SIM card.
-I tried repairing it with PC Companion but it cant do that because it wont recognize it or respond to the (hold vol down then plug in USB).
-Didnt bother try fixing it with flash tool because I knew I'd have the same results as I did with PC Companion ^^^^^^^^
-I read some people say that the USB error can be a Hardware issue but I dont think it is because my phone worked fine before all this. (Unless the USB cable fried my phone some how???? lol
-I did make a backup before I did the flashing which I put on my micro SD card, and I had that out when I tried flashing so it should be safe
I think thats it. If theres any thing else that comes to mind that might help I'll add it in when I can.
Any help would be appreciated thanks!
Force install drivers using the "Have disk" option through the device manager control panel.
If the firmware that controls the USB interface and bootloader are corrupted, it's possible that it's hard bricked and needs to be recovered using JTAG.
I've had bricked phones due to hardware failures that caused the same error.

Thanks for the reply.
My phone wont show up on the pc anymore. wont show unknown device in device manager neither.
When I first plug it in the LED shows red for a little then goes away, so I think the battery is dead, i charged it but still nothing shows up on the pc.
I would like to try and recover it using JTAG. I know how to open up the phone and all, but I dont know how to JTAG.
Could you give me some video tutorials or step by step instruction on how to do it for my phone? Also what JTAG hardware and software do I need?
thanks :]
