How can I unbrick ZTE Open with adb debug disabled?

I have a ZTE Open for Telefonica Movistar Mexico.

On my ZTE Open, adb debug is _disabled_ I was trying to update it via "More Info" menu, but it never worked. So I tried to update it via SD Update using the ztems rom [0]

It just bricked my phone and now, every time I try to update it via SD card using any ZTE Open rom (I tried with several roms), including the Movistar Mexico's one [1] I'm getting errors like this:

E:failed to verify whole-file signature E:signature verification failed Installation aborted.

No matter if I delete the first three lines of /META-INF/com/google/android/updater-script, I'm getting the same kind of errors.

Please, any ideas about this?

@nhirata: Am I wrong or you are answering to something you didn 't read (you don 't have to if you don 't), I mean what I wrote above and over above: that I cannot flash anything. Next I will use TPT if I find how. Also please tell me: have you touched this phone or opened the .zip in that link you give? Because ", I believe there's instructions in the zip file." sounds like you don 't...

here is a version 1.0 European Standard signed with AOSP keys, for those of you that have E: failed to Verify whole-file signature problems.

I have the US phone and the ZTE zip file for the US phone. Is there an easy way for me to unpack the ZTE zip file, put the AOSP keys in it, then pack it back up?

BTW, that upload link takes about 40 minutes to download unless you give them money via a credit card. And if the free download crashes, you are locked out for three hours. That's utterly useless. I've tried three times to download that file. If they can't deliver a 100 MB download I am not giving them my credit card number.

Hi znmeb:

An easy way to sign a zip? It is not dificult but you need to have signapk.jar and JDK already installed and configured. More info at http://wiki.rootzwiki.com/Signing

the easy way to find signapk on internet is look at here > http://d-h.st/cze This is an utility called Apktool (http://forum.xda-developers.com/showthread.php?t=2195680) which contains the needed file.

And I uploaded the file to the hosting server that offerts me more upload speed, because I have a damn slow internet connection ( took more than 2 hours to upload this file). If someone wants to download the file and post it in any other place its OK but I *personally* don't want to spend more time uploading it.

So be nice and upload it yourself (if it works for you ;)

ovasilis74: There is a pdf titled "Instruction of ZTE OPEN project SD card upgrade" in the download zip file. If you cannot get into the system recovery mode, then you cannot flash this image. Based on the reading of your comment, it seemed that you could do that. Perhaps I was mistaken. I apologize for trying to help.

znmeb: I am not sure if the signature file will work with the US version. ZTE should have a version : http://www.ztedevices.com/support/smart_phone/b5a2981a-1714-4ac7-89e1-630e93e220f8.html I have tried this version on an US ebay phone and it has updated for myself.... though that doesn't help your situation.

Based on the discussion though, I am guessing that if clockwork mod or some other mod has been placed on the device, the signature probably fails.

I'm trying [1] with my Telefonica-Movistar (Mexico) version. I think it will be succesful.

znmeb, I'll put that file in torrent if it works. :)

AAAAAND My problem is solved!

Thanks to all of you, guys.

Step 1. Here you have. Plase, seed: magnet:?xt=urn:btih:11d3fc176d589a12eb6f0bba5ba8edc04ff88591&dn=update-signed.zip&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80

Step 2. Put update-signed.zip on /sdcart/update-signed.zip Step 3. Turn off/reboot. Step 4. Hold on "Power" and "Volume UP" buttons. Step 5. On "android"'s recovery, Update from external SDcard Step 6. Done. Step 7. Enable remote debug: Settings -> Info -> more info -> developer -> remote debug Step 8. Be happy.

I'll write a mini-howto to let more people know how to solve this problem by using "signed" roms.

Pazos, gracias por firmarlo con AOSP, que es justo lo que yo no sabía cómo hacer. Ahora sí, a jugar con este aparatito. (=

Hello everybody hanging out there. I double check my thoughts.

The http://firefox.ztems.com works OK for with 1.0.x versions that I've checked (Movistar Spain & ZTE Open UK = US). Upgrading this way gives you a working phone but you will not be able to flash ZTE signed images from http://www.ztedevices.com. Don't worry, you will be able to root & flash cwm, and then you can flash any rom you want.

For people who has "stock 1.1" version, or upgrade their phones through CWM with ZTE 1.1 images (as found in www.ztedevices.com), flashing the image at firefox.ztems.com gives you a bootloop. then you can go android recovery and flash *ANY* rom signed with AOSP keys.

zte open is not a great device, but its fun. ZTE support is just -1 But, hey! can be part of the marketing plan? a contract with a company that does NOT answer emails (but it sends you spam) does increase the "Power by the Community" slogan/feeling

No, seriously, bad for ZTE, good for mozilla.

Is there a browser-compatible link for this? Nothing I have on my machine recognizes this string.

Never mind - I installed KTorrent (Fedora Linux 20) and it's downloading / seeding now!

Latest status:

  1. I downloaded update-signed.zip,
  2. Copied it to the SD card on my Fedora Linux system,
  3. Put the SD card in the ZTE Open,
  4. Booted into recovery mode with Volume-Up/Power,
  5. Applied the update.

The update worked ... it unpacked and copied the files. I rebooted the phone. It is coming most of the way up but not all the way up.

It boots up to a screen saying 'Firefox OS'. If I hold the power button down it will give me the 'Restart / Power Off' menu but that's all I can do with it.

I'm checking now to see if adb and fastboot can see it. I've tried a couple of reboots and there are brief periods when 'adb devices -l' lists it, but they disappear. So there may be a way I can flash it now, but it's still not all the way restored.

Latest status:

  1. The script to root the phone worked. It's now rooted.
  2. I went back into recovery mode and did a restore to factory settings. The phone now comes all the way back to a start screen.
  3. The software is showing OPEN_EU_DEV_FFOS_V1.0.0B02

I have just closed bug 956584 - the phone is now running the ZTE European 1.1 software. I'm going to give the documentation writers a couple of days to catch up before I try any more mods to the device. ;-)

I forgot to say that you need to wipe data (factory reset) *AFTER* flashing update-signed.zip, because of imcompatibilities between versions.
