ERROR - Processing of system.sin finished with errors.
please help , i cant find anything usefull than extract that file and install it , but that wont work if i soft brick it

Do you use the latest Flashtool(0.9.23.2) to flash the FTF file?
If yes, sometimes just flash FTF again right after error occurs may fix the problem.

Use this tool to backup your TA partition.
You need to backup it in Android system with adb access, not Download mode or Flash mode.
To check if your computer has adb access, simply type "adb devices" in the command window.

I see you have enabled ADB on your device, and connected to your computer. But ADB did not find your device.
Maybe you should re-install your adb driver.
You can download ADB Installer by @Snoop05 here.
After installing ADB driver correctly, you should see your device on adb device list.

[Q] [Help] Stuck at the HTC Bootloader with the sdcard, system formatted through CWM

Hello there,
Right now I'm stuck with an HTC one with its complete system wiped out i.e format cache/system/sdcard/media etc via CWM recovery throught the option in mounts and storage (I did that by mistake on CWM, forgetting about how the phone does not have an external sd card which I'm used to...) I don't think its USB debugging option was enabled either because I had fresh unlocked the bootloader so the phone was reset to factory settings, so I don't know if adb sideload is an option. (I don't know how this works either, at least not entirely... only what I learnt over the past 4-5 hours through the web) I feel like i have the adb path set up right, all I need to do is be able to access the device through my computer so I can somehow transfer the ROM zip onto the sdcard so I can install it. Can I just flash the ROM zip through fastboot? I already read around that prolly not but someone mentioned that I can flash the factory stock update... Where can I get that. Help pls! 2 months salary down the drain... replacement is not an option here... there is no customer service where I come from..

No you can't
Thank you for the quick response! This is the message I get after typing "adb devices" in the command prompt from the platform tools folder
adb server is out of date. killing...

I'd already tried this before but this time I extracted the sdk in C:\ just to see if it made any difference... I even used the command "adb remount" it still says "error device not found". Could this be because of the USB debugging option from the developers menu in settings? I can't make that change right now because i can't boot into the phone! What can i do to correct this?

My laptop that i connect to the phone is on a 64 bit operating system does it matter if the sdk i downloaded is for 32 bit?

I use the same fastboot folder I used to unlock the bootloader for all adb stuff it contains a working copy of adb
and makes sure the path is easy and correct. (no spaces)
2. I see he mentions using a laptop ..be sure your using a usb 2 port .. not the blue usb 3.0 ports their know to cause issues with adb.

Getting "device offline" with adb after 4.4 OTA

This is just weird. I went back to stock to get the 4.4 OTA. Done, now I want to reinstall TWRP and I'm getting the device offline error. Debugging is on, drivers are installed . . . what stupid mistake have I made?
OK - oddly, I reinstalled the sdk and it works. Who knows?

I have this same issue. Device shows up in "adb devices" but, shows to be "offline."
I'm running Windows8, adb version 1.0.29, with an MotoX (ATT). I cd to "platform-tools" to run adb.
---------------------------
Ok, I solved it by locating the 1.0.31 adb files here: http://forum.xda-developers.com/attachment.php?attachmentid=1724500&d=1360704125
I unzipped and replaced the adb files in the "platform-tools" folder with the ones from the above link. My issue was that the older adb files weren't causing the MotoX to prompt me to verify access from my computer. Updated adb files caused the prompt. Once, I verified my computer access - all is good!

There are a couple other things to try.
One, just get the latest ADB platform tools and see if your device shows up online using that adb.
The other thing would be to delete the adb keys on your phone. Remove /data/misc/adb/adb_keys.

[Q] PLEASE HELP!! No OS after wipe

Hello!
I have an HTC one developer edition, I did an advance wipe of my phone because it wasn't charging, it said that USB Host mode was on. It only charged when the phone was off. I decided to wipe everything but the pictures (or so I thought) but once it finished the wipe the entire OS systems was erased, know the only thing I can do is enter TWRP.
Please Help I just bought the phone!

what do you mean by doesn't read the phone? its is not detected as sideload when you type ''adb devices''?

.exe file extension might be hidden depending your windows configuration. Go ahead with the guide it should work.
Open a cmd prompt from that folder. (shift + right click in a blank space) (step 4)
with you device in twrp sideload mode (step 1,2,3 completed)
type in the cmd prompt:
Code:
adb devices
make sure it output your device s/n + sideload
then
Code:
adb sideload <name_of_rom>.zip
what rom did you downloaded?

Looking to go AOSP from Stock KK [4.4.4]

Sooooooooooo,
I have a Z1 [C6903] that I picked up yesterday. It came with 14.2.A.1.136 Jellybean 4.3.
I wanted to
Unlock bootloader
Install custom recovery
Root
Install any nice AOSP ROM [preferably LP-based]
I installed the Minimal ADB-Fastboot 1.4.
I also installed the Flashtool 0.9.18.2.
I also installed the Z1 device, Fastboot, and Flashmode drivers [version 1.6.2] from the driver folder. It first failed, and then I disabled driver verification then everything went smooth!
Device manager recognized the phone in MTP and Fastboot, and Flashmode modes. Drivers installed correctly I presume.
Then the challenges arrive:
adb devices returned it as "offline"
Android studio couldn't push a project to it because it was offline
fastboot devices identified it, but fastboot -i 0x0fce getvar version returned an error [getvar:version FAILED (command write failed (Unknown error))]
Things I've tried to do to rectify the connectivity issue:
I'm using a SurfacePro 4 so I can't switch USB ports [only have one].
I've tried different cables - they yield the same result.
I've enabled and disabled USB debugging, revoked access, unplugged and replugged, rebooted, etc. Still no change in result.
Since the device had some OTA updates pending, I ran those and now i'm on 4.4.4 with 14.4.A.0.157, with some other updates currently waiting for me to accept so they can download. I've decided to post here for help and won't run those updates unless it increases my profit
PS: Even after the updates, adb and fastboot still are unchanged in their results.
Help please
Update:
It was a freaking USB cable. I had tried two of them. None had worked.
I finally unleashed my Anker USB cable and Boom! We good to go!!!
Thanks all!:highfive::highfive::highfive::highfive:

That's what I need help with.

ahh have you tried using
Code:
adb kill-server
adb start-server
and trying again?
What should happen is the authorisation window pops up on your phone

Excellent! I did that, too. even manually closed and restarted adb.exe to no avail.
The thing is, my Z1 DOES NOT show me the authorization pop-up! Ever!
I've done this a million times on other phones, and I know the procedure. It's just that this Z1 is not showing the authorization popup
Thoughts?

I actually went ahead and tried adb on another PC with minimal adb-fastboot and adb drivers installed, and it returned the same "offline" response
Whoa!:angel:
@boydee
this could work with you
i assume that you rooted your phone you will do that:
1. open your favorite file explorer(suggest: ES File Manger)
2.go to /data/misc/adb/
3.delete "adb_keys" file
4.enable usb debugging
5.reinstall your drivers
6.open command and kill adb server(adb kill-server)
7.connect your device and run command (adb devices)
8.look at your device you will find text box telling you a new pc check always trust bla bla and click trust or something like that

this could work with you
i assume that you rooted your phone you will do that:
1. open your favorite file explorer(suggest: ES File Manger)
2.go to /data/misc/adb/
3.delete "adb_keys" file
4.enable usb debugging
5.reinstall your drivers
6.open command and kill adb server(adb kill-server)
7.connect your device and run command (adb devices)
8.look at your device you will find text box telling you a new pc check always trust bla bla and click trust or something like that

Hey, thanks for the advice!!
Finally got root [without use of PC] and when I open the /data/misc/adb/, the folder is EMPTY
A little confused there.
I did the same procedure for the PC [deleting from C:/Users/boydee/.android/] but it also was to no avail.

Hey there! Please check here for a firmware file that works for you.
When you've downloaded, use the Flashtool to flash it to your phone.
If you want help flashing it to your phone, check this thread out.
Hope that helps

This could problem with installing drivers as PC don't detect adb in debugging mode
So disable driver verification again and install drivers from flashtool remember to check
1. Fastboot drivers
2. Flashmode drivers
3. Xperia Z1 drivers
And restart
If the problem not fixed try adb universal drivers just Google it
I was have same problem with win 8.1 but I didn't all that I just installed win 7 and do it
Remember to backup ta before unlock to backup your DRM keys

Help with (I think) bricked Mi Mix

HI everyone, i have unlocked Mi Mix with EU Global ROM (rooted) and TWRP installed.
After the phone was playing up, I idiotically removed root and deleted Xposed, and it was OK, but tonight I tried to re-install originial ROM, and now can't do anything with the phone.
I can boot into TWRP, but when i try fastboot, the fastboor screen comes up for 20 seconds, then the phone boots to Mi logo, and nothing happens.
I can't get computer to recognize the phone so can't add new ROM - so unsure how to do anything now
Any help appreciated, thanks!
Jamie
Hello !! i think i can help you , well same thin happened to me and what i did was ----∑ Boot into recovery , plug your phone to computer , download Universal ADB Driver and when it detects Adb Composite click install . Then you will be able to unlock and use fastboot. Hope it helps if not im sorry , this is all i know. Good Luck !!!
If you are able to boot in to twrp why just install the original Chinese rom and start from scratch.

Hey, thanks for the reply - in TWRP though I can't see any ROM files, or anything to install?
Download a ROM (from desktop)... boot to TWRP (device)... Mount storage... Copy Rom to device... Flash ROM...

Hi, thanks for the reply. the problem is, the computer doesn't recognize phone no matter what I do, and I tried the mount storage option but it only shows the phone internal storage!
Sorry, i'm new to this all, thanks,
Jamie
There is sdcard on Mix, then if you see internal storage you can copy rom on it then when u try to flash, navigate to this zip file...
Other u can flash using MiFlashTool using adb feature....

Thanks! Yeah, I noticed it said SD card - but it's not removable, no? So i don't know how to put ROM onto it, when my computer doesn't recognise it!
Thanks

When you boot into TWRP, try "adb devices" on your PC. If it's read there, you can use the "adb push filename.zip /sdcard/" command to push the ROM to your phone and then install it.

Thanks, is adb devices the same as mimal ADB and fastboot? As in, the program? I have that installed, although it can't find phone
And sorry for knowing so little, i don't have much Android experince.
Thanks,
Jamie
Check if u have an issue with your driver when device is connected... device manager on windows 10...
If yes, check to install driver from computer (not from web or cd's or something like that), select universal USB/adb feature... and ur device will appear...

Well, I use minimal ADB and fastboot too. Just run it, and try "adb devices". If it's read, you can try the "adb push". If not, please check your Device Manager to see if it is read there.

It doesn't appear in Device Manager, and it always has done before. I installed new drivers (made sure they were correct), rebooted PC, and still doesn;'t show in device manager, so not sure what top do!
Thanks,

Damn. Not sure what to do either. Maybe download a fastboot ROM from their site and flash it trough Miflash? Maybe that'll work? If not, then I'm out of ideas.

I've 100% installed the right drivers, but the device doesn't show in device manager, or anywhere on my PC! It does charge though, which is weird

if you have a usb OTG adapter you can put a rom on an usb stick mount it in twrp and flash from there
Did you do a total wipe? And left your device totally clean?

Put your ROM in the same folder as your adb drivers folder. Hold shift while right clicking in this folder and choose "open command window here". Boot into TWRP and goto "advanced", then "adb sideload". Now write in the command prompt "adb devices". It should now show your device id and "sideload" after it. Write "adb sideload name of your rom.zip"
At least your phone isn't totally dead like mine. I powered mine off with a full charge and we to power it back on a little while later and it's totally dead now. Even Xiaomi Flash Tool won't let me flash anything. Sees the phone but won't let me flash anything. I get an error code. Xiaomi, via email says they can't service my phone because I'm in the USA. This will be my last Xiaomi phone. So pissed off
