Unaltered Desize Z won't boot anymore...

Hi!
I have 2 Desire Z devices here. One rooted with CM7 running just fine, and one untouched, with the original Froyo/Sense ROM. and here's the problem:
Out of nothing the phone won't boot anymore and is stuck at the HTC-Logo screen.
I can still boot into (the original unaltered) hboot and fastboot.
When I select Facrory Reset from hboot, I think it does flash the recover image, but that won't boot either.
Selecting Recovery in hboot just displays an icon in the middle of the screen (a phone with a yellow warning sign in front)
I find guides on how to backup and restore for rooted phones all over the place, but I'd like to keep that device in original condition. Just want it working again.
So maybe there's a way to flash a working recovery rom through fastboot?
Maybe we can do some diagnosis using ADB in hboot?
Oh, and it's probably too late but backing up the contacts (and other data) would be great
Any help really appreciated!
Thanks!
Daniel

Sounds like you might be suffering from the 'bad' emmc problem.
There's information on the error here http://forum.xda-developers.com/showthread.php?t=1039504
In short, the internal memory card gets corrupted and cannot be written too, if you do have this problem there is nothing you can do, but get a replacement.

Thanks! I'll contact HTC...
Still I can still connect to USB on the bootloader, do you think I have a chance of dumping my data partition so I can try to recover things later?

if you know how to do a dump I'd say its worth a shot. The emmc (i think) can still be read, just not written to.
-Nipqer

I don't know how to dump using fastboot. I found a way to upload an image to the phone, but I can't download.
Can anyone point me to a guide on how to dump Data using ADB/Fastboot?

Is there any way to get a shell in the bootloader and access the filesystem?

You might be able to use adb shell in recovery mode, but seeing as you don't have clockwork mod it may not work.
Give it a go anyway.

No it doesn't work just like that...
I couldn't find any USB drivers that workes (not from the sdk and not from HTC Sync). The drivers from PDANet installed correctly though.
adb doesn't recognize the device, but it is recognized in Windows' device manager.
fastboot works though, but it can't download anything, right?
I'm not sure if it doesn't work because of the driver or if it's just not supposed to work with the normal launcher.
I guess I should just tell the guy his contacts are gone... I doubt it helps to put a note in, "please restore my contacts if possible", when I send it to HTC.
I just hope my device won't break the same way... But at least I have clockworkmod on it and I do regular backups and have everything synced to Exchange, so it won't be that much of a problem for me...
Thanks for all the help!

help did I brick my phone?

All,
I have a big problem. When I try to start my phone I get the black screen with google and the unlocked padloack, after which the screen goes dark and nothing happens anymore.
What I did before this are two things. I had been mukking around with the screen resolution (I had it set at 240 and 280, as some apps did not show up in the market) also downloaded LCD density to solve the market issue.
I then rebooted the device and entered CWM to do a backup which as far as I knew succeeded. unfortunately after rebooting, see the above.
I have tried a couple of reboots, tried restoring the nandroid (the above was the only one I had). that didn't work, so tried to connect to the PC to load a new ICS rom (original 4.0.4 by google), unfortunately my device can not go into USB mode in CMW (it comes up with UMS lunfile missing....)
so I am woring in circles. can't start the device to download a rom, can't open USM to load a ROM to start the device again.....
any help would be appriciated
thanks
Patrick

hey
flash a new ROM via fastboot then, there are enough guides
-Syn
Edit: Alternatively, flash the stock Google ROM via GNex toolkit and go from scratch.

as mentioned, I can't get a rom on the phone so that I can flash it.
I can't start the phone to donwload one, and can't connect it to usb to get one on the storage....
sorry, you mentioned fastboot.... not USB.
so connect it to usb cable. I then entered fastboot devices, no number came up, as was also the case with ADB. thinkin I might not have the correct USB drivers for my windows machine. any idea where to get teh correct one?

To flash stock images the files are on your PC, not the phone.
If you can get the phone to boot into fastboot (via vol up + vol dn + power) and get your PC to recognize it you're good to go.

thats the issue. pc cannot recognize the phone, so cannot get any files from the PC to the phone (ie. cannot get a rom file to the phone...)

Either directly from Samsung or download the GNex Toolkit (You might want to use it anyways to flash the stock image), the drivers come with it.
After you installed the drivers and have you phone plugged in, go to the device manager to check if it is connected properly.

For the drivers, I would recommend you remove all old drivers and install these. If you don't know how to install them, or are having issues, look here.

I had a similar issue with regard to my PC recognizing the drivers. I googled around and found that people were having success with installing the PdaNet drivers, so maybe you can try that too. I had installed the Android SDK as well as the PdaNet drivers, and I eventually got mine to work.
I would probably follow Efrant's links first though - if that doesn't work for you, then maybe you can try PdaNet drivers and/or installing the SDK.
Good luck.

Why not just do a factory reset from within recovery?
¢ £®0π π€XU$ |||

the factory reset didn't help, the phone just wouldn't go past the black lockscreen. So in the end I used the galaxy nexus toolkit. installed the drivers for the PC, was able to go through fastboot and push files and flash a new rom.
Al is now solved, just need to do a lot of work to bring the phone back to where it was and make a backup asap.
thansk all for the help!

Hard Bricked LG E980 USB device not recognised

My LG E980 is bricked. I can access download mode and that is it! I am unable to boot into recovery,
and the hard reset screen simply sits there forever. My computer only recognizes my device as an "unknown usb device."
I'm unsure what can be done about this, but I feel like this is better than the infamous QHSUB icon displayed when the device cannot be recovered.
Does anyone have a remedy for this problem?? I have GOT to fix this phone and can't afford to Jtag the device, but I'm losing hope that this is possible, PLEASE help. :crying:

Have you installed the LG drivers for your pc and tried the unbrick method?

Yeah dude there's an unbrick method. If this doesn't work just sell the phone on Ebay. http://forum.xda-developers.com/showthread.php?t=2302660

There is never a time when this device cant be recovered. even the qhusb is a fairly simple fix. ill go ahead and make a sdcard boot image tonight. do you have a 32gb sdcard? (or larger) and an sdcard reader, if you have those two things i can make an unbrick.img that you flash toi the sdcard and put in the non-booting phone and it will get you to download mode/recovery mode. ill have to check out what partitions are where as i dont wish to include my efs along with it all .

Happened to me.
1. With the phone on download mode and plugged in the computer; uninstall the unknown device on your computer using device manager. The computer should try to get the drivers for your phone.
2. If it doesn't. Repeat step one and install the drivers first.
That worked for me hopefully I'll work for you.

I do have a 16gb sd card, but I can pick up at 32 gb sd at my local best buy. I have an Asus laptop running windows 8 and it has an SD card reader. I am a little confused (semi-noob) as to how this will work because my phone will boot up, and the led changes colors on the home button for about 4 seconds and then the light stops flashing. The phone is stuck on the LG boot screen, and there is no way out of it but to pull the battery or to reset with power button. Of course no recovery as previously mentioned. I really just want to get back to stock, but I can't manage to get both the windows 8 computers I've tried to detect the phone in download mode. Ever since I switched to the Candykat rom 4.4 the computer wasn't able to recognize the phone, even when the phone was fully functional inside the rom.
I have tried it on my dads windows 7 laptop as well with no dice. Instaled LG drivers, uninstalled LG Drivers, uninstalled device from the Device Manager. I've done everything I could think of. I previously was in a Philz touch recovery, but every rom I tried to flash wouldn't work. I tried to flash another recovery from inside it and then the device bricked like it is now. What a head ache. If you think this method would work, I am more than willing to try it, just unfamiliar with what I need to do on my end.

Okay

I will give your method a shot, but I have done this a lot already. The only thing I can think of is I usually unplug the phone from the computer right after deleting the drivers and uninstalling in device manager. Maybe I should just leave the phone plugged in and see if the computer automatically downloads the drivers, but I don't think it will because I've tried to update the drivers before. It gives me an error code "10" and says the device has malfunction or stopped working This phone has been undetectable via USB since flashing the candykat 4.4 rom. Every computer I've tried (3) and every USB cable (3 again) has displayed it as an "unknown device"

I dont know lg's download mode, kdz, tot etc all that well. im more of a samsung guy. however qualcomm since the s4 chipset has allowed for sdcards that are properly formatted to boot the os instead of the internal emmc. here is a decent guide, just need to make teh image for this device. this will let your device boot no matter how bad it gets you are welcome to try with 16gb, the rule of thumb i know of is as big as teh emmc is use that same size or larger sdcard, however some people have had sucess withs maller, just not many that i know of. http://forum.xda-developers.com/showthread.php?t=2439367
however afaik the only way to reflash teh bootloader partitions is via kdz/download mode so perhaps the sdcard will let you get into that mode and then you can flash, so long as you keep your sdcard like that it will boot fully, but in order ot get your sdcard back you need to repair teh files on your phone .

Thanks

Wow, that sounds awesome. I followed most of that. I access download mode on the device by pressing vol up and down simultaneously and plugging in the usb cable. I am more willing to try this, and if it works I will pay you from my paypal. I guess all I need now are those files to run to the sd card. I read the tutorial you posted for the samsung and downloaded the windows disk manager. I am eager to try this method, though it is admittedly very new to me.. If you can post those files, I will follow the instructions you give and pay you a little bit of money for your help!
I am a broke college student so it won't be much, but I really appreciate your response and information on this method with the qualcomm s4.

Here is the unbrick image. follow the guide for your platform (gunna guess windows) and write this to your sdcard after backing it up. from there you need to restore your partitions by flashing them .

Okay so I bought the 32 gb sd card. Just wrote the .img file you sent me to the sd card.
I powered on the phone and nothing happened, I got the same LG screen where the led flashes and then stops.
I followed that guide, but am I supposed to go to download mode instead of just powering on the device?
I got a little confused by the samsung jargon lol. I just want to know after I've written the unbrick.zip to the sd card
how do I get my phone to recognize the card is there? And once I am able to do that how do I "restore my partitions by flashing them?"
I do have the factory firmware set to flash through lg flashtool, but the phone can't be detected of course due to the usb issue.
Just want to say thanks for walking me through it this far, I feel like I'm close hopefully but unsure what to do next.

you wrote the image to the sdcard? i wonder if its because you still have the low level bootloaders that it may not be booting from the sdcard, normally this is done to fix qhusb errored devices. as for restoring the partitions all you would need to do is one its booted up push the unbrick image to the phone and use rooted adb shell to write it back onto your phone.

Possible hope??

I meant I used the windows tool to write the debrick.img to the sd card. But no dice, the device isn't recognised.
However! I installed a driver clean up tool and now if I plug in the device it is recognized as Android Original ADB Interface.
The LG Flashtools even says the port is ready! But I get the error code "10" "device cannot start, A request for the USB device descriptor failed."
So now I am stuck on that instead lol. This just sucks.

that sucks about the sdcard, it must be because you arent "truly" bricked. sorry i thought it would help ya :/.

What is the driver repair tool you used? I know this thread is old but I'm having the same problem. I was trying to root my E980 and now my computer wont recognize my device. The phone works perfect, its just when I plug it in to the computer it isnt recognized. How can I fix this?

+1
Just wondering if anyone's come across a solution to this besides a sledge hammer... been having the same "Code 10: Device failed to start" when in Download Mode, though Windows finds a driver fine when the phone is stuck on the LG screen... doesn't help much, though, 'cause it won't receive adb commands. I manually installed the LG USB Composite Device driver, which added a modem and a COM port, both of which Windows recognized to be active, but the LG FlashTool USB Viewer showed no open pipes. I'm a relative noob, so please feel free to point out the obvious, like an alternative to adb that the phone can always receive or a way to brick it the rest of the way so the MicroSD trick will work.

I came across this problem like the OP and just wanna let everyone know that you have to use computer with USB 2.0 port then the driver issue would be fixed.

How to get T-Mob S3 off (third) Samsung splash screen to access data

Can anyone please assist to get data off an S3 which sticks at the blue-backed throbbing SAMSUNG splash screen just after the android rocket take-off.
The history is that the phone started constant-rebooting and I left it off for a few weeks. Then I took it into a shop to get the power switch replaced and the repairer noticed that it no longer reboots, it just sticks at that SAMSUNG screen. When neither of us could get it into safe mode, he diagnosed that it was "definitely" a software problem. Resetting caches from recovery mode doesn't do anything and as I am trying to get data off it, I am a bit reluctant to follow other solutions I have found here and do a master reset!
I THINK this device is rooted (with towelroot)? See below
I can get to an Odin screen and can get the device recognised on the computer and wondered if I could do resets from there with one of the 4 files included with 3.07. Curiously enough one of them did succeed (though the success was too quick to convince me it had actually flashed very much) and the device did reboot but still got stuck at the same splash screen! Taking the battery out and restarting/cleaning caches again etc didn't help and now, none of the Odin files will 'flash' successfully, which is why I am not sure if I am still rooted or if something is returned to stock. I am just not sure which file or what exactly flashed successfully and what it did to the ROM, bootloader, CID, etc etc etc. SO I am assuming that if I can still load Odin and get the S3 recognised, it is still rooted.
Is there anything else I can try either through odin or independently to get me into the os please? I have loaded skipsoft and run it and it has connected to the S3 (and changed things) just by connecting to the computer in download mode: But I can't see where in skipsoft I can diagnose or correct whatever is wrong

Flash TWRP via Odin, boot into TWRP, mount data partition, connect the phone to a computer, and try to copy the phone's data to the computer.

What that guy said ^^^ Install a new OS for your system which should replace your old one. You don't need to boot TWRP if you are going to boot a new OS. My method involves you losing all your data so you have been warned. You can get the stable version for that here http://techbeasts.com/update-t-mobi...o-android-4-3-jelly-bean-t999uvuemjc-guide/2/. Good luck

Thanks for that guys but I have apparently already loaded Philz and it SAYS it has backed up the data and/or storage to sc card and I am wondering if Ican restore it to a new Galaxy J7. I especially need to figure out if I can restore telephone text messages from the S3 onto the J7 but i could make do for the moment with knowing whether such messages have made their way onto the SD card.
Yes, I am a bit reluctant to do a full wipe and restore until I can figure this out.
Or if I can access the files through my computer as you suggest, what file / format would they be in?

If you used Philz to create a backup, I don't think you'll be able to restore the data to the J7, but I could be wrong because Philz hasnt been updated for a long time which means there may be no Philz for the J7.
Philz can only be restored with Philz and possibly cwm.

I got Philz installed through Skipsoft but am wondering whether there is any newer utility I can install over whatever Skipsoft has put there? Or is that what TWRP is?
I am a bit reluctant to install anything through TWRP if it is going to not only overwrite the OS but also delete all the data I am trying to access! But is there any utility which might conceivably get my phone working again without deleting all my data please?
If I load T999UVUEMJC_T999TMBEMJC_TMB,md5 through Odin, will it delete all my data??

Flashing twrp should not over write the rom, only the recovery.
Was the phone recognized as a removable when it was booted into philz?

Why did you ask me that? 'cos I was pretty sure it was recognised but checked again and it isn't recognised by the computer at all when I plug it in (and obviously isn't recognised by Odin)
Philz shows as Touch 6.26.6 and ClockworkMod v 6.0.4.8

Why would I ask? Because twrp can mount the phone as a removable drive to copy off the data as you wanted to do in your original post.

Sorry to harp but are we agreed generally that there is no way of getting this phone working again, - whether with some utility or by re-flashing the stock or some new ROM?
Once the phone starts hanging at that third throbbing SAMSUNG screen, is it effectively dead save only for the purposes of getting data off it as a media device please? I really need to access my text messages and couldn't even identify them on a file directory and wouldn't know what format they were in if I could access the file browser. That was sorta a last resort but I am now downloading T999UVUEMJC_T999TMBEMJC_TMB for installation through Odin? Or for installation through Philz if I can get the file onto the SD card.

Did you try twrp and use a otg usb?
It really depends on how much your time is worth.

If the phone is not recognised by the computer, either the drivers are not working properly, the USB port is damaged, or the USB cable is not compatible with Odin.
Until the phone is recognised in Odin, you can't flash a stock rom from sammobile.com.

I am not exactly a newbie at this but I am beginning to wonder if I havent just got a developing massive hardware failure. I have tried a number of computers, including ones which formerly recognised the computer/cable/S3 setup and none can now recognise the phone, eg in Odin.
The phone is detected on plugin to Windows 10 (with the recognition beep) and is then not seen in windows explorer. Changing cables doesn't do anything. I am assuming it should automatically appear on the drop-down menu in TWRP's app in the playstore. That menu only shows a phone I plugged into the system about 6 months ago (without it being rooted) and asks for root permissions on this now-nonexistent phone.
The phone is not now recognised as it was up till only a few days ago in XP. Nothing is now recognised on a Mac, though on all three units the phone charges.
Restarting in download mode a few times changes nothing.

The only other thing I can think of is putting some TWRP file (?) on an SD card, booting into recover/Philz and can i not install TWRP or reflash some ROM from there?

I'm not sure if twrp can be flashed from Philz as I have always flashed TWRP via Odin.
You have done everything I would have done to get the phone recognized short of a installing a fresh installation of a Windows OS.
You could also try Heimdall (http://glassechidna.com.au/heimdall/).

Locked bootloader by mistake, can't use the phone now

Hey all,
I just got a OnePlus 5T and because I needed a specific system language I decided to flash a custom ROM. I unlocked the bootloader, flashed Derpfest on it and it was all good until I made a mistake. From the Developers options I unchecked "OEM Unlocking" and then when I restarted into the bootloader I did a fastboot oem lock
Now the phone says it's corrupted and it won't boot. Since it's bootloader is locked I can't unlock it, I can't go into recovery and I can't start the phone. Is there anything else I can do to get it back? I don't care about wiping everything at this point, I'm just trying to get it back to a working state.
I want to add I did try the Unbrick tool https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012 but I am getting stuck at the drivers. Windows won't see QHUSB_BULK in device manager and I don't see anywhere else where the driver for the phone might be. I do see the device when doing fastboot devices but again, can't see what drivers is using.
Thanks!

The unbrick tool is your best bet, what you need to do is follow the instructions. If its windows 10, you can go to device manager and update drivers from there. Make sure you are logged in as admin. Also some antivirus don't like the MSM tool so you may need to disable that.
Ensure the sequence is right. Connect usb wire to computer, press volume up, connect usb c to phone. Some ppl have tried pressing both volume up and down at the same time to make it work (same way as resolving Sahara error). If it boots first thing you need to do is back up efs.
Second you need to run these commands
adb shell
su
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
exit.
It will save the persist.img on your phone internal memory. Save this as well as efs somewhere safe. Also share the persist.img with me cause I need it for the OPlus 5t for my phone.
Hope it helps

Thanks for the help! I ended up finding a different Windows PC with no memory of the drivers for this phone so I was able to install them in the correct order and then run the MSM tool to get the phone back to stock Oreo. From there I unlocked the bootloader again to install TWRP and then my custom ROM.

That is superb. If you could do the other bit I would really appreciate it.
Thanks

Hey there, sorry I totally mis-read the last part of your original post as something that I should do and I didn't see that you need that. Since I used the MDM tool I didn't bother to try your way first and since the phone wasn't mine to keep I already gave it to the owner so I don't have access to it anymore.
Again, very sorry about that.

No dramas. I also got it from some one else who was kind enough to lend it to me and let me root it and wipe it clean and then get the file and start using his phone again.
Thanks
