Okay, where to start.. I think I have bricked my phone pretty good.
Here is the approximate list of things that happened.
I wanted to try to update to froyo, so I downloaded z4root, worked beautifully
Followed all the directions to install clockwork mod (including reading far enough ahead to find out the one in the directions was for the 7015, but gave the link for the 7005 version later) - Worked like a charm
BACKED UP SYSTEM as instructed
Then here is where things went south. I attempted to install the Cyanogen Mod froyo based. I followed the directions, including backing up softmac and wpa_supplicant files. And it would not start up. I could get it into recovery mode but not to start fully. I tried doing the restore, it couldn't mount the SD Card where the backup was. Being knowledgeable enough to dangerous in Linux, I used ADB Shell and tried various things to try to find out where the SD Card or recovery image failed. I had also been trying to locate FWDN as I saw people had done fixes with that, but I couldn't get it to load in FWDN "Mode". I figured if I could replace the recovery program on there that doesn't work with the one that does, it should in theory allow me to reboot into the correct recovery mode and let me pull the files from my SD Card. After about 15 minutes of shuffling around, I ended up mounting the \system folder where I found a file called recovery. Looked to be the right size. So I made a modified batch file that would instruct it to load from that folder.
After that mistake, all of the sudden, the vtc driver that I had installed did see the unit. I was like Joy! Joy! I fired up fwdn but since I didn't have the original files that it "liked" I used an lk.rom, but I think it wasn't from an X5A but from a lonpad. Now I don't even get COBY on the screen.
But wait, I'm even more dangerous. I got the hardware ID that it's currently using on the USB bus, edited first the vtc ini file to see if I can reload a different rom. It detects it, but FWDN gives me "bad boot" error or something like that. But I'm a trooper, if I'm gonna kill it, I'm gonna kill it good. I change the SDK/ADB driver to recognize the device. And it seems to recognize it. Then I went to try "fastboot flash recovery recovery.x5ag.img " which I had NEVER been able get the unit into fastboot mode, and it goes through and does it. Then I do a fastboot reboot to see if I can get it to come up in recovery mode, but I can't.
Then the final bright idea comes up on me.. Hey, I have the backup from SD card, what if I zip it up, call it update.zip, and do a fastboot update?
Now ADB can make some kind of connection to it, but when I try to shell I get:
- exec '/system/bin/sh' failed: No such file or directory (2) -
ADB State always reports device or unknown never bootloader
ADB remount comes back with remount failed: Invalid argument
ADB push into the / or /system folders (in an attempt to push a copy of sh there) fails saying read only file system
ADB push to /sys comes back with failed to copy: No such file or directory
So, that's where I am.. I think I really really REALLY bricked this thing... although the fact that I can still ADB to it leaves some shimmer of hope.
Thanks,
Joe
can u get into the boot loader at all? If so you are not Bricked you will just need to reinstall the entire system using fast boot. You may be able to restore the default OS using an update.zip file. It may be named something different for your device. All you do with that is place it on the root of the SD card and when the bootloader boots it finds the file and flashes the phone.
I can't get fastboot to recognize the device, it goes right to the ADB bridge. Where I can run some limited ADB commands that are recognized.. If I could get it to start up in fastboot mode, that would likely solve the issue, provided I can get the correct working update.zip file, rather than me trying to fudge one from the clockworkmod backup.
do you have any hardware buttons on device? turning on with volume up or down (or back) gives you differing USB ID's to device manager - obviously you want fastboot mode. (use device manager on ADB Bridge (Details) to get your ID - i think its DEED for fastboot and D00D for fwdn)
otherwise... you can force boot a new bootrom. It's what I did on my telechips device. Find tcboot.rom - put it in the same directory as fwdn
1. Open your device
2. Unsolder your battery + terminal
3. While turning on the device, place a short - screwdriver/pin etc - across pins 7/8 of the NAND chip (for 5 seconds)
4. FWDN should bring up a message about flashing bootrom
5. Reboot (and resolder battery cable)
Note: this obviously is pretty hardcore - but i went from brick, to black screen brick, to full restore via this method.
Hi,
I am looking for some help as I did something stupid...
I came across some posting that explained that the moto has an unused partition under /cache that could be used for the dalvik-cache.
So I tried to move the dalvik-cache there and link /data/dalvik-cache to this new location.
Now the problem is that I get an "unfortunately the location-service has stopped" message all the time that makes the device unusuable (as soon as I press ok the same warning appears again).
When I try to boot into recovery I get a "dead android robot".
I can however access the device via adb, unfortunately I am not able to get a root shell. My device is rooted, but su in an adb-shell just hangs.
If I could only get a root-shell I could undo my changes and hopefully my device will work again, but I have to idea on what to try...
Can anone help me here?

The dead android bot is normal for stock recovery, if you didn't install a custom one. You can always flash a custom recovery using fastboot, and wipe the dalvik-cache and regular caches. Or, in the "dead android bot" screen, you can press the Vol+ key for about 15 secs, then tap the Power button, then scroll using the Vol buttons to something that says wipe cache. You might have to wipe dalvik-cache as well, if you can. I forget where the options are, since I haven't used the stock recovery in so long, sorry!
Ok, I managed to get beyond the "dead android" and from the menu I did a "wipe cache parition". That ran for some minutes, then it rebooted.
But after that I still have the same problem. The continuous "unfortunately the location-service has stopped" messages still persist.
Any other ideas?
Do you have an unlocked bootloader? If you do, the simplest solution may be to flash back to a stock ROM.

Yes my bootloader is unlocked. But I don't want to loose too much...
I believe the problem is only a permission-problem in my new /cache/dalvik-cache directory (/data/dalvik-cache now links there).
So all I would need is a way to get a root-shell (the device is rooted).
I can do a "adb shell" as normal user but that does not have the permissions to even look into /cache and for whatever reason when I type "su" I don't get an error nor do I become root but the command simply hangs...
The system as such still seems to work, e.g. my Moto still connects to my hotspot and I can ping it from there.
The even seems to be an "adb root" command, but that does not work on my adb. Is there a version of adb somewhere that would honor adb root?
Anyone with another idea on how to get a root-shell in my situation
Sorry, I don't know enough about adb commands to change the directory back to the default.
I assume you have usb debugging enabled and your computer is a trusted machine?
USB debugging is definitely enabled, whether or not I've set up my PC as trusted I don't remember.
If I didn't could that explain why I can get a shell but not as root or would you without a trusted computer not even get a shell?
Ok, issue resolved.
I've flashed clockworkmod recovery and cleared the dalvik-cache with that. That did the trick.
And moving my 300MB dalivk-cache to /cache seems to have worked and frees up memory for me, even better.
Finally the reason I could not get root in the adb shell was that when I type su in the adb-shell a superuser-request pops up on the phone that you have to acknowlege. But with constant warnings poping up I did not even see that...
Thanks for all support.
For the Developer options, look under Root access. Did you grant root access to ADB and apps?
When you type su, look at the phone's screen. Are you prompted to grant root access to ADB?
I use the patch to android feature of lucky patcher then when i connect my cp to my laptop it cant connect, so i panicked and want to re flash my OS.. i forget that it cant detect through adb so i formatted it via twrp.. that's where it begins.. my cp wont open and it cant detect through adb or fastboot :crying::crying: and when i finally make it again through bootloader after doing this http://forum.xda-developers.com/android/development/hard-bricked-zenfone-unbrick-method-to-t3131911.. but it still doesn't detect through adb and showing this after i click factory reset
E:failed to mount /cache (Block device required)
E:Still unable to mount /cache! giveup!
RESULT: FAIL (problem with write cache command!)
HELP ME PLEEEEEAASE.. :crying:
Aw. Sad. It's too late. Install Adb driver to your computer to detect the usb from your phone to computer. But, now I don't have any idea to help you from that problem. I'm sorry. But, You should ask this to professional on how to fix like that your zenfone problem. Go on youtube and type, Windroidica and watch the video on how to fix Bootloop or bricked zenfone there. I hope it helps. Goodluck
I installed the OTA update last night and it's just looping through the "alcatel one touch" and "smart move" screens. It's been like that for hours.
I need assistance in getting into recovery mode, and hopefully getting my files off the device.
I have downloaded android-studio and am about to install it to get adb and fastboot, and have downloaded the drivers for the idol 3. At this point when it's plugged in, my computer doesn't recognize the device.
If you did not have usb debugging enabled BEFORE the boot loop installing adb and fastboot now won't do you any good. Are you still able to get into recovery and is it twrp or the factory recovery? Without a direct way to get the phone into bootloader regretfully the only solution is to send it in for warranty repair (or replacement via your credit card if you paid that way under purchase protection)
Are you trying to remove the data to prevent access by others or because you need the data? Did you make any backups to external sd or copied to the pc?
I as well am stuck in bootloop. Was able to get into factory recovery and reset phone several times. Still no luck. I have a TWRP backup, but how to I do a temporary boot into it? Only option available in factory recovery was to sideload via ADB, but no luck using fastboot commands there. Phoned Alcatel and they have referred me back to Amazon. Amazon only wants to refund me, won't exchange! Of course I bought at the pre-order price. Any help would be greatly appreciated.

The factory reset killed you....if you had usb debugging enabled prior and had not done a factory reset (which kills /data) you could have possibly gotten to an adb shell long enough to do an adb reboot bootloader. The problem is there's no way now to get you into bootloader....you can't get to it from recovery (factory).
If you purchased it by credit card you might see if their purchase protection (typically 60-90 days) allows a claim submission for a replacement....in this case they would cut you a check for the cost of a replacement after mailing in your old one. That's the only solution I see to remain at the $199 price.
You could also see if amazon will issue a $50 credit to your account in addition to return to allow for repurchase. Unlikely but possible.
Ok thanks for the input and advice. As a last ditch effort, is there a way to create or modify the twrp file as a "signed" zip file so that I could boot into it via stock recovery. This was how I rooted my old Galaxy S2, although it was a CWM recovery.

Nothing so far has worked in that regard...in fact I created a update.zip using "zipme" to replace the build.prop that another user says the factory recovery refused to process.
Without a full factory rom to pull needed info in or the source code to compile one we can't do some of the things which would "save" the device.

Can you post a screenshot where the option is? I'm not doubting your word but perhaps he's looking in the wrong place? I'm back on TWRP so can't look in the stock recovery myself.

There is no option for screenshot while the phone is in the stock recovery. I need a camera to take a picture of the menu. I can do this later. The menu however looks like this:
Code:
reboot system now
apply update from ADB
apply update from sdcard
apply update from phone storage
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down
view recovery log

If it's right off the main page like that then I can confirm it's not on the 6045. It's been one of the main issues with folks bricking their devices...if their rom gets messed up and they have factory recovery they have no way to get into bootloader to do anything to repair the device. Seems alcatel needs to add the reboot to bootloader to our recovery. I wonder where we could report that.
Is there a way to "lock" recovery so the updates cannot replace twrp? TWRP allows adb access and reboot to bootloader.

This is a snapshot from the recovery menu of 6039y.
The short answer of your question regarding the "lock" is ... no. If a longer explanation is needed ... this is from the update file, a link to which was provided by you:
Code:
if ! applypatch -c EMMC:/dev/block/bootdevice/by-name/recovery:18393344:f9062580503eb61b315a5d12c5c6b3bb133aa4b2; then
....etc.
what it does is to check the sha1 sum of the recovery partition and if the sha1 sum doesn't match to f9062580503eb61b315a5d12c5c6b3bb133aa4b2 will continue with an overwriting of the recovery partition and then will apply a patch. It can't be changed because the whole update will fail.
yep no bootloader
I've got reboot to boatloader on main page from stock recovery on my 6045k

Back to the "lock" question. Probably it is possible the OTA update to be slightly modified and then to be flashed through the TWRP recovery (there is an option in TWRP to skip the signature verification ... the verification will fail if the zip file is modified). But I prefer to wait for the OTA update of the 6039y, as I want to perform some tests with the upgrade.

I am in the same boat as OP re the state my Idol 3 (6045i) is currently in. I also unchecked superuser but did not unroot completely before installing the update. I have not yet done a data wipe through recovery though. Unfortunately, back when I rooted the phone I did NOT check the box telling the phone to remember the computer/RSA key for future use. As a result, now when the phone is stuck at the white/animated Alcatel boot logo I can see the phone under adb devices, but it shows as unauthorized.
One thing that did seem odd, was browsing through stock recovery when trying to browse to apply an update from either phone storage or the SD card, no files are showing up at all. All it is showing is the folder root ( /.. ) in both instances and nothing else. Even after I attempted loading several system update and twrp images (in .zip and .img formats) on the SD card from my computer, once loaded in the phone none of the files show up through stock recovery. Is this SD card not compatible/formatted wrong or is something else going on?
Is there any current method to gaining access to the phone via adb manupulating the adbkey files in the $User$/Home/.android folder? I do currently have the adbkey files on my Mac from connecting the phone previously. I'm assuming these files are uniquely generated hashes?
That is ridiculous if the 6045k has bootloader access from recovery and 6045i does not. What would be the reasoning for this?

Does the sha1 sum of your recovery happen to match f9062580503eb61b315a5d12c5c6b3bb133aa4b2 ? If so it could solve some issues but why do I suddenly think all 3 models have their own recovery?

adb reboot bootloader won't work even with it showing unauthorized? If you can get into bootloader you can fix /system without messing up your /data (don't wipe data or you lose adb entirely...you may figure out how to add the correct hash if we can find how it's generated)
Here's some info on the hashes you might find useful taken from: http://nelenkov.blogspot.com/2013/02/secure-usb-debugging-in-android-422.html
Secure ADB implementation
The ADB host authentication functionality is enabled by default when the ro.adb.secure system property is set to 1, and there is no way to disable it via the system settings interface (which is a good thing). The device is initially in the OFFLINE state and only goes into the ONLINE state once the host has authenticated. As you may already know, hosts use RSA keys in order to authenticate to the ADB daemon on the device. Authentication is typically a three step process:
After a host tries to connect, the device sends and AUTH message of type TOKEN that includes a 20 byte random value (read from /dev/urandom).
The host responds with a SIGNATURE packet that includes a SHA1withRSA signature of the random token with one of its private keys.
The device tries to verify the received signature, and if signature verification succeeds, it responds with a CONNECT message and goes into the ONLINE state. If verification fails, either because the signature value doesn't match or because there is no corresponding public key to verify with, the device sends another AUTH TOKEN with a new random value, so that the host can try authenticating again (slowing down if the number of failures goes over a certain threshold).
Signature verification typically fails the first time you connect the device to a new host because it doesn't yet have the host key. In that case the host sends its public key in an AUTH RSAPUBLICKEY message. The device takes the MD5 hash of that key and displays it in the 'Allow USB debugging' confirmation dialog. Since adbd is a native daemon, the key needs to be passed to the main Android OS. This is accomplished by simply writing the key to a local socket (aptly named, 'adbd'). When you enable ADB debugging from the developer settings screen, a thread that listens to the 'adbd' socket is started. When it receives a message starting with "PK" it treats it as a public key, parses it, calculates the MD5 hash and displays the confirmation dialog (an activity actually, part of the SystemUI package). If you tap 'OK', it sends a simple simple "OK" response and adbd uses the key to verify the authentication message (otherwise it just stays offline). In case you check the 'Always allow from this computer' checkbox, the public key is written to disk and automatically used for signature verification the next time you connect to the same host. The allow/deny debugging functionality, along with starting/stopping the adbd daemon, is exposed as public methods of the UsbDeviceManager system service.
We've described the ADB authentication protocol in some detail, but haven't said much about the actual keys used in the process. Those are 2048-bit RSA keys and are generated by the local ADB server. They are typically stored in $HOME/.android as adbkey and adbkey.pub. On Windows that usually translates to %USERPOFILE%\.android, but keys might end up in C:\Windows\System32\config\systemprofile\.android in some cases (see issue 49465). The default key directory can be overridden by setting the ANDROID_SDK_HOME environment variable. If the ADB_VENDOR_KEYS environment variable is set, the directory it points to is also searched for keys. If no keys are found in any of the above locations, a new key pair is generated and saved. On the device, keys are stored in the /data/misc/adb/adb_keys file, and new authorized keys are appended to the same file as you accept them. Read-only 'vendor keys' are stored in the /adb_keys file, but it doesn't seem to exist on current Nexus devices. The private key is in standard OpenSSL PEM format, while the public one consists of the Base 64 encoded key followed by a `[email protected]` user identifier, separated by space. The user identifier doesn't seem to be used at the moment and is only meaningful on Unix-based OS'es, on Windows it is always '[email protected]'.
While the USB debugging confirmation dialog helpfully displays a key fingerprint to let you verify you are connected to the expected host, the adb client doesn't have a handy command to print the fingerprint of the host key. You might think that there is little room for confusion: after all there is only one cable plugged to a single machine, but if you are running a couple of VMs, thing can get a little fuzzy. Here's one of way of displaying the host key's fingerprint in the same format the confirmation dialog uses (run in $HOME/.android or specify the full path to the public key file):
awk '{print $1}' < adbkey.pub|openssl base64 -A -d -a \
|openssl md5 -c|awk '{print $2}'|tr '[:lower:]' '[:upper:]'
We've reviewed how secure ADB debugging is implemented and have shown why it is needed, but just to show that all of this solves a real problem, we'll finish off with a screenshot of what a failed ADB attack against an 4.2.2 device from another Android device looks like:

Just tested using adb reboot bootloader again and this is the result: error: device unauthorized. Please check the confirmation dialog on your device.
Something else I tried was running fastboot commands in the narrow window that the phone initially boots (black screen with Android logo) but that didn't seem to work either. I tried:
fastboot reboot-bootloader
fastboot -i 0x1bbb reboot-bootloader
fastboot -i 0x1bbb devices
I noticed if you plug the phone into the computer via USB while the phone is off, it will briefly power on to the Android logo/black screen before flashing the battery status once and turning off. Is this an opportunity to send fastboot or adb commands to the phone?
I'll try messing with the adbkey stuff later when I have time to dig into it.
There is a tool from Alcatel (TCL) which can perform upgrades of the device from a Windows PC. You can try it if nothing else helps. There are two COM ports available under Windows when the device is powered off and the USB cable is connected to the phone. This tool use them to perform some checks on the device and probably will continue with an upgrade (it says that all of your data will be wiped after the upgrade etc. so there is a possibility to overwrite everything with a stock image) ... there are instructions how to work with it. The link is from the French support section of Alcatel. Despite that the program has support for 6039 and 6045 is not clear for which of their versions.

You can't do fastboot commands until the phone is IN bootloader....so you'd have to do adb reboot bootloader

etc....

It is possible the program to download these images from a server.
I found another interesting thing. The device has a download mode. It is activated when the phone is powered off and connected to a PC. You must wait the display to turn off after the charging battery symbol and then to press and hold both volume keys, after which to press and hold the power button (without releasing these for the volume). But still don't know what to do in this mode. No device is detected on my Linux box when the phone is in this state. Probably I should try in Windows.
Also when the Alcatel upgrade tool was trying to detect the phone I'm almost sure that one of the COM ports was
Qualcomm HS-USB Diagnostics 9006
there is a lot information for other devices how this can be used to unbrick your phone, so this is a some start. The images which the people flash through it are in raw format.
Any help would be much appreciated... Haven't toyed around with phones for some time but I must have gotten into the deep end with this Sony Xperia 5 II, not sure what to do here.
Using OrangeFox recovery, I must have unmounted or done something to the phone's /system mount point because I can't flash any ROMs or restore anything without /system available. While a "System" option does appear in the "Mount" menu's checklist, tapping on it does nothing and I can only mount "Data" and "oem".
Here's what's happening when I try to remount the system via adb:
mount -o remount,rw /system which returns:
mount: /system: mount point does not exist.
Out of curiosity I tried this as well if it's even related:
adb disable-verity but get:
Overlayfs setup failed with error No such device or address
verity not enabled - ENG build
Is there a way to mount /system as a partition given the above doesn't work?
Are you sure partition /system physically exists?
If it doesn't exist then re-flash Stock ROM.
Is there a way to check? And if it should exist, can it be created?
Currently the only partitions on the phone are metadata, Data and a pair of storage/sdcard1.
Prior to this issue (or before I mucked around in the recovery), I was able to successfully flash a ROM's system.img but cannot do the same now due to "no such file or directory".
As a result I'm suspecting it might have been there before, but could be wrong.
Ok I'll try getting the stock ROM tomorrow, at the moment the Sony Mobile Flasher tool by Androxyde is stuck on Sending getvar: product so the phone might even have trouble flashing via flash mode.
Are there any other known tools/programs for Sony devices to flash stock firmware with? Or a direct link to a flashable rom could work wonders.
Ok there was no luck using either the Xperia Flash Tool or Newflasher as they both yielded errors or just hang at an early stage in the ROM flashing, made sure it wasn't a driver or USB issue which begets the question...
Does the bootloader need to be re-locked? Currently at work but if there are some ideas worth throwing around I'm all ears.
Resolved, might as well say exactly what worked for me in case it happens to anyone else:
1. Perform a format through the recovery.
2. Download the right firmware through XperiFirm 5.6.1.
3. Move/Copy the downloaded firmware files into Newflasher 4.2. No making subfolders or anything, just move all these files into the same path the newflasher application is in.
4. Not sure if it was a necessary step but I used Unsin 1.13 to extract the boot_X-FLASH-ALL-2389.sin file created from step 2 which created an image (drag and drop this boot_x-etc-etc SIN file into the Unsin executable to extract it).
5. Place the boot_x-etc.img file created via Unsin into the Newflasher folder, just along with all the other files in the directory.
6. Ensure the Xperia 5 II is powered off. Hold the volume down key while plugging it into a USB 2.0 port until the phone's LED goes green.
7. Launch newflasher, and press f. For all other prompts, press n. You should see the stock firmware getting flashed in newflasher.
Will take a few minutes, but is an important step as it rebuilds the system, even going as far as restoring the bootloader to the stock one which you'll see can get booted into rather than a custom recovery as done in step 9 later.
8. Once step 7 is done, unplug the phone to turn it off (or press the power button until the LED goes away).
9. Hold both the power button and volume down keys, and let go of just the power button to enter the bootloader.
10. This is where the option to /mount system can be selected and was successfully mounted (a custom recovery like the one I had could not do this).
11. Now that /system is actually mounted, you can proceed to open fastboot from within the bootloader and go flashing whatever. For example, what I did immediately after mounting /system was open fastboot, plug my phone into the computer and ran all the commands in step 4 for this particular ROM: https://forum.xda-developers.com/t/...icial-lineageos-18-1-for-xperia-5-ii.4221435/
Pretty explicit, but it explains that all along it was just a matter of reflashing the stock firmware via newflasher which let me enter the default bootloader and mount /system without further problems.
Hope this helps anyone else in the future.
