I have a ZTE Avail 2 which I recently managed to root with Cydia Impactor. Afterwards I managed to screw it up by removing too many stock apps with Titanium. I did it carefully, one by one, and for a few days everything seemed to work fine. But then apps started force-closing, '<name of app here> has stopped working', etc. Factory reset doesnt help, it just restores me to the same screwed up state I'm in now. I already know why, it's because I removed some of the stock apps, which I now realize it needs. I'm currently stuck on the AT&T logo when powering on, it never gets any further. But even while it was messed up it was still halfway-operable, and now this. This device's subforum on Android Forums is all but non-existent, and XDA doesnt seem to have anything for it.

What I need is a 100% stock ROM (pre-rooted if possible) that I can flash, along with instructions on how to flash it. I have some experience flashing ASUS devices and Samsung devices, mainly the Transformer pad, and the Note 2, but have also rooted miscellaneous other devices in the past without alot of issues. But I have no experience with ZTE. I've already checked the manaufacturer's website for some kind of recovery software I can use to restore it, there doesnt seem to be anything.

Thanks for any help!

Just out of curiosity you ever figure out a solution? I have the AIO branded version of it.

build.prop?

If needed, I could back up my /system folder and send it to you.

did you ever get around to doing this? there is supposedly a stock image on androidforums but when I opened the Zip, all it had was the stock apps, no build.prop, which I think I blew away with xblast (xposed plugin). now I hang on the boot screen image. there is a stock Rom for the z993 our there, which I suppose I could use, because they are supposed to be the same phone, just different carriers... but then I need to get the at&t apn's and it is just a PITA. so if you could post /system backup or just a stock build.prop, that would be great!

(I'd post links to these rooms but I guess I'm too new of a member... I can provide them if needed.)

I'm way late on this, but just thought I'd post to say that I no longer have the device, and I was never able to fix it.In any case, I hope the rest of you guys get it fixed. It seemed to be a halfway decent phone, although a bit sluggish at times. But beyond that, with all the bloat removed, I'd say it ran pretty well for the duration of time that I had it (less than a month). I currently have a GNote 3 (T-Mobile) and a GNote Pro 12.2" now and it's just awesome, I'm really loving them.

Just like "AnonVendetta83" messed up using Titanium.

Now desperately looking for Stock ROM or any working custom ROM to bring phone back to life.:crying:

There is a working custom Rom for the z993 (identical hardware, different customized software for AIO, another cell provider). All you will need to do is change/update the data provider stuff so you can still use 3g and mms's. Plenty of info on this online on what needs to be changed.

You can get this Rom over at androidforums.com

http://androidforums.com/prelude-all-things-root/792279-zte-prelude-z993-stock-unrooted-rom-aio.html

There is also a cwm recovery there that works on this phone, and a partial /system backup by someone else for the z992... it is just apps and what not.

If they aren't available anymore, let me know and ill see if I still have them saved somewhere for you.

Thank you so very much Alex

I was wondering if I can just simply place the rom zip on the root of your sdcard and continue without doing "Install CWM - ZTE Prelude (Z993) Root&Recovery" step???

Honestly I have absolutely no idea how to do CWM steps as they come so complicated to me.

You need to install the custom recovery... It is the only way to install the zip file. If you just have the zip and go into the stock recovery I don't think you can select which zip to install

Thnx Alex

I would highly appreciate if anyone tell me what ADB Driver I should use for ZTE Z992. I almost understood all the procedure in the links but now the problem is despite I tried different ADB Drivers, but still ADB reboot-bootloader boots phone again in Normal bootloader.

Also Fastboot devices command does not see the phone, while ADB Devices command see it.

Seems bootloader is locked. Right? What should I do?

This is the method I used when I rooted my avail2 :

http://androidforums.com/zte-avail-2-zte-prelude/821217-how-root-zte-avail-2-z992-guide.html

The author (and I) just used the included drivers from zte that come with the phone. From what I remember, fastboot worked fine. Just hold the volume down button then turn the phone on. It will seem to lock on the start screen, but this is the bootloader. Then connect your cable and try your fastboot commands.

If you are already rooted, you can just download the package here

http://androidforums.com/prelude-all-things-root/797487-cwm-recovery-installer-zte-prelude.html

And skip the middle section, using the impactor to root (13 and 14).

Depending on what's wrong with your phone, you could also try just using the stock recovery and doing a system reset there. It will wipe any bad custom settings, but if the rom is still viable it might get you up and running again. It got me out of a bootloop without re-romming the whole thing. And with titanium backup or system app mover you can reinstall anything you need in the system partition.

A bit to much fiddling resulted in disaster

Hello XDA forum users,

I'm about ready to toss this phone in the trash. I have an AT&T Avail 2 with model number z992, which is apparently manufactured by a company called ZTE. First I think it would be helpful to explain what I've done to the phone and perhaps others out there can tell me if I've destroyed the phone or if it can be fixed.

A friend of mine sold me the phone for 10 bucks, its in great condition which is why its such a shame that it seems perma-bricked. I have no need for the phone aspect of the device, I simply wanted to "convert" it to a handheld media/application player, like an ipod or tablet for example. The phone comes with several bundled software applications that I find completely useless and wanted them removed, EX. AT&T Navigator and other AT&T software, plus a bunch of google applications.

The first thing I did when I decided to try and customize it was to use Kango's root tool which worked and rooted the phone. I was all excited that it worked and continued by installing the Super User application which allowed me to gain full control over the device. (I should have stopped there.) After the successful phone root I then installed a 3rd party app called NoBloat and used its uninstall options to remove a lot of stuff. I couldn't tell you exactly what all was removed but looking back, it must have been more important than I realized at the time. I know I took out all the AT&T software, then all the Google stuff to, which destroyed the play store. I didn't take out anything that seemed like a system file but apparently the Google stuff is the system files. The phone still worked in this state but it was erratic and things like Contacts would crash even if it was not running. So I considered that a failed attempt and commenced to do a factory reset using the recovery menu (Vol Up + Menu Key + Power button) but the factory reset didn't work, well not like it was supposed to. I had used the restore option before and it made the phone work like it was brand new. Now when the phone is powered on it will boot to the initial setup and ask me to choose a language, then it will get as far as the wireless connection screen (sometime not even that far) and the phone reports that "Unfortunately, Setup Wizard has stopped." and then I tap OK and the setup wizard restarts at the language screen. This is the state it is in now and I do not know how to fix it, I'm beginning to think there currently is no method to fix this.

Things I've tried so far include installing minimal ADB-Fastboot to try and sideload various ROM images, the ones I found here and other places. The phone is not recognized by Windows 7 though and the ADB does not work like it did on a motorola phone I did this to before. I've also purchased an inexpensive 8GB microSD chip with an adapter so I could put the ROM info on that and tried the "Update from external storage option" and that seems like it would work but none of the ROM's I've used will install. I guess because there is some kind of security feature built into the phones hardware which checks the data files for specific tags/sizes and therefore won't accept any of the ROMS I've tried.

There is no means to access the old file system anymore like most guides show, I do not have any CWM's installed nor any backup data whatsoever. It's been reset and now it seems the data it used to restore itself is, while not completely missing, damaged and will not reload anymore. All the guides I've read or watched usually show the user in the operating system or using software on a PC to type out commands. None of that works on this phone though, the phone as I just described it is basically bricked. Is there anything that can fix this, or is the phone a paper weight now? A functional ROM image from AT&T seems unlikely as they have absolutely no relevant information about this on the commercial website and the help and support seems like it's setup for old people who don't understand technology at all. If anyone out there has experience with issues like this then by all means let me know. If more information is necessary then I will be glad to provide it if available.

Alright I did manage to figure out how to make the computer see the phone as an ADB device and the minimal ADB interface shows the device now when I type ADB devices at the command prompt. Though this ADB thing seems irrelevant considering I can do the same thing by using the SD card adapter. So I don't know if this was useful or not. The ADB prompt shows a device number of P752A15.

Before I was unable to make the device show up at all in the ADB list. The problem now is how to make the phone accept a ROM, at this point I don't even care if the ROM is the default factory ROM or some random ROM made by a devoted user. The issue I encounter each time is that the built in recovery option to restore from an SD card will not accept the ROM's I've tried so far, and my research on this seems to indicate that I need a custom recovery option. This is apparently called the ClockWorkMod but as to how I install that without a functional operating system on the device is a mystery still. I've tried using a file called recovery.zip and but it does not show up when I view the contents of the SD card when the card is in the phone.

I feel like an idiot because I've done this to other phones for my family and friends, you know jailbreaking an iPhone, and rooted a Galaxy S3 once but this phone seems like its not going to be as easy as those others. I guess AT&T made sure that if you alter it, it breaks the phone. I'll check back later and see if anyone has dropped a line or two here in response to my inquiry.

Thank you and have good day.

Ok, been a while since I've used this phone, but hopefully this will help. I assume you have the kaw202_recoveryflasher.zip file. Once you extract it, look for the .img file. Try running these adb commands

adb.exe push cwm-z993.img /cache

adb.exe shell "su -c 'dd if=/cache/cwm-z993.img of=/dev/block/mmcblk0p17'

This should flash cwm if your phone is rooted and adb shell is working.

I have not come across that particular file yet, I did try to google it and the only results it had were two and one of those was this post. Would you mind telling me where I might find a copy of the kaw202_recoverflasher.zip?

I managed to find the zip you were talking about and have downloaded it, for anyone else looking for it. I am unable to post links but I would have linked to the files you mentioned. For others looking for the same zip file search for "CWM Recovery Installer ZTE PRELUDE". That's the title of the thread I found the file on that Alex mentioned above. The instructions on the page don't seem like they apply to the situation I'm stuck in but I'll give it a whirl anyway and see if the files work.

If this forum is like the others I've read through so far then there is no real answer to the issue. The phone seems kind of new and not many of the power users on these forums use rinky dink phones like this one. You guys all have the 600 dollar models I guess. What bugs me about this this phone and the state I managed to put it in, is that the damn thing was programmed the first time when it was made. So it seems to me like there should be a way to reprogram the phone the same way the factory did it. Think about it, when they make the phones they don't have any information on the phone at all. It's completely empty, so there must be a way to load the software for the phone even if the phone has no data at all in the main storage. If the files in the recovery flasher.zip file work then I'll post back the results but if it's like the other files I've messed around with (which didn't do anything) then I'm throwing it in the trash can.

Anyway thanks for your response and for pointing me in a different direction Alex :)

HELL YEAH!!! It worked thank you Alex,

I would have never figured this out without your help! The phone now has a version of CWM on it and the recovery menu is different. I just tried to install a ROM and it said successful. After the phone rebooted went back to the setup screen from ZTE but it still did the same thing. However this is progress and I should be able to "wander in the dark" and figure out a way to use the CWM to install a completely new rom. Any recommendations on a ROM to use for the z992?

Good news, I was able to fix it using the information Alex guided me to find. Since there doesn't appear to be a stock AT&T version of the ROM I ended up using the Azazel ROM. Which at first failed even though it was installed, this I determined was due to the old ROM image still being partially active on the system partition. So I formatted the system partition to and tried again. This time it worked and the phone seems fully functional again, and best of all the annoying bloatware is not present and the apps are not crashing. I consider this issue resolved. Thank you again Alex I will be sure to leave a thanks on your post.

Glad I could help, but none of the work was done by me, the guys over at android central did all the heavy lifting, I just pointed you in the right direction. I have a stock system e m image around here somewhere if you need it, tho installation will be a bit more complicated. If azazels rom ever gives you issues, ill dig it up and try and help you install it.

    Just like "AnonVendetta83" messed up using Titanium.

    Now desperately looking for Stock ROM or any working custom ROM to bring phone back to life.:crying:

    There is a working custom Rom for the z993 (identical hardware, different customized software for AIO, another cell provider). All you will need to do is change/update the data provider stuff so you can still use 3g and mms's. Plenty of info on this online on what needs to be changed.

    You can get this Rom over at androidforums.com

    http://androidforums.com/prelude-all-things-root/792279-zte-prelude-z993-stock-unrooted-rom-aio.html

    There is also a cwm recovery there that works on this phone, and a partial /system backup by someone else for the z992... it is just apps and what not.

    If they aren't available anymore, let me know and ill see if I still have them saved somewhere for you.

    If you have this phone don't download the above file, it's pure garbage.

    I managed to get in touch with a very helpful support at ZTE earlier this year who was kind enough to include the factory firmware on their website for this phone. On this page there is a down arrow beside the word "DESCRIPTION". Press the arrow to get a drop down menu. Select "SUPPORT". They also included a manual so if you don't know how to use recovery to install the update.zip you should download the manual as well. Here is the link.

    https://www.zteusa.com/att-avail2

    This is the address to the link for downloading the firmware file. It is 392MB.
