thanks a lot, dtriguero!

BUT NOW I GOT MY V55 HALF-BRICKED.......Could anyone help me to recover it?

my scenario is like this:

1, flashed a recovery called cwm 5.5.0.4.

2, now everytime i booted the devices, it went into the recovery, no matter what i pressed, vol + or Vol - didn't make any difference;

3, i dont have any backup or rom zip in the internal storage, and in recovery i cant see my ext-sd card;

4, couldn't find any device in windows when plugged in USB port. no adb or fastboot connection;

ANYONE KNOW HOW TO RECOVER A DEVICE LIKE THIS?

Please help， thanks a lot!
[Miscellaneous Android Development] Mr. Hat:
Flash TWRP zip through CWM, if it doesn' t work, flash it with ADB. Then boot to TWRP, go to Mounts and mount external sd. Then you will be able to see files on your sd card, flash whatever ROM you want, done.

Either that or you can flash CWM, that is able to install zip from external storage, but TWRP is simpler to find and install, thanks to two opinions ADB/.zip

It is not a difficult problem to solve, if you have trouble with anything above, search this thread, EVERY problem, that can occur during the process is solved there somewhere already, thanks.
[Miscellaneous Android Development] canserman:
thanks for your reply, but maybe u missed what i wrote above:

3, i dont have any backup or rom zip in the internal storage, and in recovery i cant see my ext-sd card;

4, couldn't find any device in windows when plugged in USB port. no adb or fastboot connection;

i dont have any recovery or rom in the internal storgae now, and could not access the device via usb connection, neither adb/fastboot nor usb mass storage...

so how do i get a TWRP zip out of nothing?
[Miscellaneous Android Development] Mr. Hat:
I thought that you can only RESTORE from internal and "Instal .zip" was working with SD.

Anyway, I'm not the one who missed something. If your device is not recognized, it's problem with drivers in your PC ... that problem is solved literaly one page back. So stop blaming me for anything, even if my post was totaly wrong, at least I'm trying to save your tablet, unlike you, seeing that you couldn't even read few pages of this thread.

Because as I said, ALL of that IS already solved there. Even the whole "internal storage recovery, no adb ..." situation, not only the drivers.

And by there I dont mean XDA, I mean this thread.
[Miscellaneous Android Development] joe.stone:
Which recovery is on your tab ?

If stock , start in frm mode (vol+ & power) if other like cwm or twrp start the tab in recovery , connect it to your computer and wait a few minutes until it is shown via adb.

You can check the connection with adb devices.
[Miscellaneous Android Development] bioan:
Anything Joe? :)
[Miscellaneous Android Development] Mr. Hat:
It has already been answered bioan, no.

Thanks again for help. Yup, it's my fault the description is not clear.

I'd like to try it again here.

1,Before this happened ,v55 can be recognized with my win7 laptop, as same as n1 or my galaxy nexus.

2,Problem:

i could not access the device internal storage with any methods already known

what i did:

1, failed in trying to find sd-ext in recovery : can't find mount sd-ext or similar option in mount menu;

2, failed in trying another sd card : same as 1

3, failed in trying boot into ftm mode: recovery loop, no matter i use vol +/- & power or the reboot option in recovery;

4, failed in trying connect v55 with adb/fastboot : no known or unknown device found in system, also changed to desktop, the same;

recovery is cwm 5.5.0.4.

so, if anyone can provide any opinions other than above, i'd like to try and give feedback.

BTW: i'm thinking that jtag could help? but cant find any information about v55 jtag....
[Miscellaneous Android Development] joe.stone:
Does the windows play sound when you connect the tab to the usb ? If not it can be the hardware error of the tab or the data cable.

I am sure that the adb must work under cwm . It takes a lot of time until it is shown (minutes after pluged in ) , but should work . In recovery the init rc starts the adbd service . The first version of cwm did not let us to transfer big files to the tab using adb push , but my modified version of cwm let .

EDIT : I have tested it takes a minute after the plug in until the device is accesssible via adb using cwm.

FTM works only if you have stock recovery . The main difference between the standard mode and ftm mode that stock recovery starts adbd in ftm mode while in standard mode not.

Try to reinstall ZTE_Tablet_USB_Driver.exe. ZTE_Tablet_USB_Driver

Try to connect the tab to a linux or another win computer. Under linux adb is accessible right after you plug the tab the usb while in windows it takes a few minutes .
[Miscellaneous Android Development] canserman:
V55 came back! Thanks a lot, joe! I tried the driver you gave me and manically the adb device appeared in my laptop!

Then i flashed twrp immediately， booted into system, everything OK now!!

[Miscellaneous Android Development] bioan:
Joe is the debugging log fully enabled? I can't see any error on logcat. There must be something wrong with hw acceleration on CM9 and CM10. Every other app that is not bundled with the ROM for example Chrome is not working properly. Choppy scrolling, artefacts and slow loading. I remember this problem on early Desire S ics ports and Sensation also. Thank you!
[Miscellaneous Android Development] joe.stone:
Yes , debugging is enabled . Only ril logs is not shown in standard logcat (you need -b radio).

I think it is a kernel issue. I am waiting for ZTE to release either V9S ICS kernel source either v66, v68 ICS kernel source.There are some functions which not exist in our kernel.
[Miscellaneous Android Development] bioan:
They used a hack for hw acceleration. It works on any 2.x kernel. Nexus One, Desire and HD2 used this hack. Let me see if I can find something.

I really hope you will find something useful.
[Miscellaneous Android Development] joe.stone:
I read this threads . The following is already in our system :

Backported kgsl drivers in kernel

New ICS adreno libs from Qualcomm , ( I am testing the new adreno libs for JB now on my testbuild)

This time I wont do anything with this part as I am waiting for a 3.x kernel source for one of a compatible tablet (V9S , V66, V68).V9S already got ICS , so I think it will be accessible soon.

On Which ROM ?

Youtube is working , and flash not working as expected on JB .

It is a youtube bug , if the language is turkish youtube crash. See the donanimhaber forum.
[Miscellaneous Android Development] Djabolic:
BTW; As with the latest update it is longer crashing for me Joe. My language setting is Turkish. I'm using it like that since the latest build.

[Miscellaneous Android Development] Iggys Pop:
Guys, goo.im is telling me that a gapps update is available. The new one is dated 10/11/12. The one I've been using is dated like 07/26/12. Should I flash the newer gapps? Out since I'm not running into any issues just leave it alone? Any advice would be greatly appreciated. Thanks again Joe for your amazing work sir!
[Miscellaneous Android Development] Djabolic:
I've flashed the new gapps from gooManager and nothing is broken right now. Everything is fine.
[Miscellaneous Android Development] bioan:
How much screen-on time do you guys get?

CM9: A little over 4 hours

CM10: Almost 3 hours.

On CM9 I get 1 hour extra of screen on time. I use the stock settings: smartass v2, 432-1180. Maybe with some other settings I could get 5 hours of screen-on time?

Thanks!
[Miscellaneous Android Development] Iggys Pop:
Anyone else see the ROM update for CM-10 on goo manager yesterday? Anyone

else dl and install yet? Joe, any other changes not listed in changelog? FINALLY, did you get a chance to look into the camera app another member posted earlier (didn't quote him), I ask because I was gonna give it a shot, all the build.prop changes and whatnot included. My question: before I fool with it, does it even look feasible? If so I'll play with it a Lil and see what's up...
[Miscellaneous Android Development] Djabolic:
I've also installed that, I haven't noticed any changes.
[Miscellaneous Android Development] joe.stone:
Now the rom is odexed , maybe this way we will have some more performance and battery life , shorter boot time.

All the graphical drivers are native . No drivers are copied from HC .

There is a new file manager which can operate under root permission too .

Camera app is not crashing , but still not working the camera. The preview routine needs to be fixed. It sends invalid data to the kernel .

Now I am working on these routines using ioctl calls. I hope there is no much to get a working camera.

Anyone who is using my rom feel free to try tweaks . If a tweak is working it will be included.
[Miscellaneous Android Development] bioan:
So there are improvements on graphics? Should the animations be smoother? Once I get home I will try it. Thanks!
[Miscellaneous Android Development] bioan:
Did anyone manage to download the latest version for V71A? I would like a mirror if possible. The download speed is horrible on goo.im. Thanks!
[Miscellaneous Android Development] bioan:
I've found one weird problem. The tablet is very smooth in landscape but choppy in portrait mode. Why? I can't understand.

To spot the problem easier, just install nova launcher and scroll in portrait and then in landscape. You will see a big difference. Thank you!

L.E: Battery life on latest build is awesome. I started from 84% and got over 4 hours of screen on time. Excelent! I've changed the governor to ondemand.

Anyone else having issues with USB mass storage? Also, once I use a SD card on my device, it's no longer usable on my laptop without formatting it. Odd. Hasn't been an issue with any other Android device I've used. Anyone else having similar issues, any insight?
[Miscellaneous Android Development] joe.stone:
I have tried it . Unplugged the sd from the tab then put it to a card reader . My laptop reads it without issues.
[Miscellaneous Android Development] Iggys Pop:
Ok, I've done a little research... I went all the way back to my stock recovery and checked a few things out. Keep in mind I'm using a V55. Anywho, I tried unifying my sd card and using my card reader on my laptop. It's still telling me to format prior to reading the card from my laptop. I not only formatted the card I'd been using but tried two other cards that were working fine on my laptop prior to being mounted on my tablet. From what I can tell however, it seems to be an issue with ES File Explorer. I deduced this when I realized that when I mounted my tablet via USB to my laptop, when browsing my sd it wasn't showing recent changes I had made using ES...I had moved files around,etc. I had to disconnect tablet from laptop, unmount then remount my sd card, then it shows the correct directories, etc. When I get a lil more time I plan on nixing ES from the equation entirely and see if it still remains an issue. Anyone else out there use ES for browsing? If so have you encountered any problems similar to what I'm experiencing.

---------- Post added at 12:23 AM ---------- Previous post was at 12:14 AM ----------

Ok, to clarify my issue with USB mass storage... When I connected my tablet to my laptop, the laptop recognized a CD-rom device that was "empty". I couldn't access my tablets internal/external storage. The way I finally solved this was I "ejected" the CD-rom drive, I received an "error while ejecting drive" which I dismissed, after a moment, my tablet was recognized as a media storage device giving me access to to both the internal/external storage via the laptop. Is this normal? Anyone else experiencing this as well? Please don't miss-construe these posts as complaints, just trying to share info and learn a little along the way lol. Thanks again for everyone's contributions! :)
[Miscellaneous Android Development] sangemaru:
This is very weird. What brightness settings / rom version (build date) / wireless connectivity settings are you using?

My battery life has started dropping for the last few months to about a maximum of 6-7 hours but it used to be above 8 hours, with almost-minimal brightness (which is still quite bright for indoors), 140-1400Mhz on smartassv2.
[Miscellaneous Android Development] bioan:
25% brightness, latest build on that date, not the 03 nov.one. Wifi always on, airplane mode on. I use it a lot for web browsing. I can see a difference between my settings and your settings. I use 432 as min and 1188 as max.
[Miscellaneous Android Development] joe.stone:
This is the windows driver fault. It can happen , that the device connected and a cdrom drive appaers named ZTE. In stock system it points to /system/etc/pcsuite.iso. This file contains the windows driver. When you install the driver , the installation process ejects this cdrom and start recognizing the tab as MTP device.

You have selected one of the correct process. The other solution is to reinstall the driver (ZTE_Tablet_USB_Driver.exe).

I use this driver from the v03b update package.
[Miscellaneous Android Development] bioan:
I hope Joe doesn't mind if we talk a bit about battery life.

I cannot pass 4-5 hours of screen on with a standby of over 40 hours.

What are your screen on time and settings?

Thanks!

bugs

Joe, I noticed several bugs.

(1) When i using voice call (gsm) or skype call, display flashing ON and OFF uncontrollably (almost blinking).

(2) When WiFi is on, call quality on both sides is very bad. Whether talking via speakerphone or BT headset.

(3) Sometimes, the voice call through BT does not work, but the stereo music works fine, so I have to reset the tablet

Can You fix that?

What are the chances that will soon get Android 4.2 on our tablet? :)
[Miscellaneous Android Development] EnricoTFYKD:
I've just updated the tablet to the latest OTA (Paranoid 2.53 - 4 nov 2012) and the newest gapps. I see that now the camera app doesn't FC, but anyway BT tethering from my phone (GNex) still cause the tablet to switch off after an unsuccessful soft boot. Let me know if there's a way I can help.
[Miscellaneous Android Development] darkj2k:
Can someone help me to mirror the latest build of "cm-10-20121103-UNOFFICIAL-V71A.zip" to 4Share? I tried to d/l this file from Goo.im with PC and Goomanager many times but always stuck in 99%. Thanks in advance.

[Miscellaneous Android Development] daffyno:
when will be supported HWA???
[Miscellaneous Android Development] joe.stone:
No , I forgot to give credits and someone did not find the kernel sources (even they were published) so the thread was closed due to GPL compliance failure. So I put the source link to the top of the op from the end and gave credits . This was the reason of the first post change.

@canserman :

ultravioletnanokitty is working on V55 .

Now the bad news :

Yesterday I have ordered a new phone and when it arrives I think I will finish developing and supporting Smarttab. So maybe there will be no more public builds and all previous versions will be removed as well.

I will read this topic and will answer support questions.

I do not know when will publish the next version , until that time my jobs wont be accessible as well as sources are deleted too.

hi joe, could this rom be any helpful to to v55?

BTW: P4 is a wcdma tablet.
[Miscellaneous Android Development] joe.stone:
The following devices are almost the same so it is not so easy to determine what is Mypad :

ZTE V9S, ZTE V55 , ZTE V71, ZTE V11 , ZTE V66 , ZTE V68.

I extracted the files , It created a folder V9S . V9S has almost the same kernel as ours it is bootoable on our tab. The main problem with the exe package is the firmware files ( sbl mbns , appsboot.mbn) . Flashing these files can brick the device , because it was not made to our device. So I think it very risky to flash it to our device.

The lib folders contains libchromatix_imx074 libs it means it uses the same camera chip as V9S . So mypad seems to be a V9S clone with smaller screen.

Also build.prop tells it exactly that it is a V9S .

ro.product.board=V9S

ro.product.device=V9S

Mypad P4=V9S .

this means that camera problem can be solved?

ZTE is so weird。。。。

check this video， p4 used exactly the same model as V55.

I know nothing about manufacture, but this seems absurd they use a totally different hardware or software design for something so similar

:confused:
[Miscellaneous Android Development] joe.stone:
They are using almost the same hardware . They can have different camera , emmc, display . It is enough to be not 100% compatible.

Especially the firmware . This is just sw , but a small difference can cause lost imei or bricked tablet.

In case of p4 it is using imx074 camera , and 8GB storage (as I know) while V55 has ov5640 and 16GB . p4 using imx074 camera as well V9S but V9S has a different screen. I wrote it earlier that the kernel used by these devices are almost fully compatible each other. For example the v71 kernel works on v11 , but the touch is not working and the screen is rotated , v71 kernel can work on v55 , but there are touch issues . These small differencies can cause useless . If the zte release the kernel source for ics to one of the following devices it will help : v9s, v66 , v68 . p4.
