Here`s my impressions and doubts:

Bought my v987 from Hotmid with Bruno`s 4.1 rom, root and 6.0.3.0 cwm

Everything was fine.

Made nandroid backup and, being confused a bit with this topic roms, mods and tools,

decided to try other roms first.

Flashed first release of Baidu (slow, phone getting really hot), Miui (slow, low on ram)

and then I wanted to revert to my nandroid backup of Bruno`s 4.1

I pulled my backup, then, on the first boot got warning:

"damaged internal sd card". Shock, panic - you can imagine.

In explorer there was no internal sd card.

Got back to CWM and made factory reset. Everything went fine.

Internal SD was alive again. :)

Why that happened?

Does that mean that flashing chinese rom repartitioned EMMC to stock values

and pulling back nandroid backup made mess on stock partition sizes?

Now I am on stock storage settings: 1Gb system (internal, userdata, - what is the correct name?) and

2Gb internal "SD card"

Am I?

Can I just simply flash v2 and v3, without mod, and later, if I like. flash mod (and then reflash rom).

Or I will again have "damaged internal card" issue.

Thanks Bruno and others

:)
[Miscellaneous Android Development] bgcngm:
Don't know what happened, it's hard to answer to that question.

If you have 2GB of space for the internal sdcard partition, then it is as stock.

Yes, you can flash it directly without mod. For the Android 4.2.1 based custom ROMs you should only use the alternate re-partitioning mod and in that case you don't need to re-install the ROM. Formatting userdata and then restoring a previous backup (using nandroid backup/restore) will do the job.
[Miscellaneous Android Development] bgcngm:
Okay, today I got some free time and managed to update post #4. I really hope it is more clear now. :p

change of 3G without changing the cards

Hi Bruno, i would like to know if i could change the 3G card connection in your V987 ( Huawei U8836D) Rom by menu like it was possible in your ZTE V970 Rom?

I think this is a very good feature without changing the cards in the slots.

I would have it on the V987 too if i buy this phone or install it on my Huawai U8836D?

thanks for answer and thanks for your work - your ROMs are the best
[Miscellaneous Android Development] bgcngm:
No, unfortunately V987 does not support 3G switch feature.

Hi,

I have some trouble with disabling data roaming...I set data roaming offline (uncheck) but after some time it activates itsel (happens for sim 1 only)f?! Anyone else having this problem?

Kind regards,

Floris
[Miscellaneous Android Development] zperetz:
Cannot confirm exactly this bug, but have my own: I'm working in 2 countries, and one SIM always in roaming. Data roaming switched off on provider level.

So even if I have active data transfer for SIM1 it automatically switches to SIM2 data (and raise data roaming error), when SIM1 is not available.

The interesting point is when I tried to flash boot.img from v2 data roaming didn't raise the error.
[Miscellaneous Android Development] tsiglas:
Has anyone hear complanes about call quality...sometimes my friends tell that they hear their voice double......
[Miscellaneous Android Development] metzner:
no....quality is good

Fixed/found my own problem...if I´m still using data on sim 2 while sim 1 roaming (working in 2 countrys as well) and switch data to sim 1 before it is on its home network the phone asks if it should enable roaming for sim 1 ...and probably I said yes...so my own fault

I suspect it may be related to busybox. Try deleting group, gshadow, shadow and passwd from /system/etc. I will check that as well later when I'm back home.

Open /system/etc/mkshrc and delete the alias for su. ;)

I have big problem.

USB cable is not recognized. Device not charging with android on.

Is not possible flash Extended user data mod. I get message: BROM ERROR:S_DL_GET_DRAM_SETTINGS_FAIL_(5054)

Stock partition and complete backup is possible flash with no problem. But still no charging.

Battery life is bad.

I tried several chargers,cables, computers, recoveries, Roms...
[Miscellaneous Android Development] bgcngm:
Seems to be a hardware problem. I suggest you to install the stock update.zip fro the external sdcard, clearing all userdata and testing. If it still has problems, contact the seller and send it back for warranty.
[Miscellaneous Android Development] bgcngm:
Okay, I found the culprit. It had nothing to do with busybox. The problem was the use of an old adb daemon binary. The reason I was using it was because we could get a root shell intermediately after adb shell command and also because adb remount worked. I just never noticed it caused this nasty side-effect.

So, the solution is to recompile boot.img with the stock adbd (or a new insecure adbd). I'll post the fixed boot.img soon.
[Miscellaneous Android Development] bgcngm:
I have found a newer insecure adbd and repacked boot.img with it. Everything is now working (adb install now works and adb remount / root is possible)! :victory:

Just install the attached file through CWM recovery.

Important: Only for Android 4.2.1 based ROMs.
[Miscellaneous Android Development] tsiglas:
Is this instalation necessary for all users of your rom 4.2.1 or just for those who work with 'adb'????
[Miscellaneous Android Development] bgcngm:
Can be installed, but there's no benefit unless you use adb. It only fixes the previously mentioned problem.

i recently bought a HTC One clone. It comes with a 1.2 ghz quadcore processor, a 12(?)mp camera and standard 4.2.1 jellybean.

No offense Bruno, but I see I waited a solution that does not come.
[Miscellaneous Android Development] bgcngm:
Well, good for you. No one is forced to use my custom ROMs and everyone should use what fits better to their needs.

As for the bug you mention, it has been there since this model was first released. In the beginning there were serious issues with the "back" button, but seems it got attenuated with newer kernels from ZTE. If it doesn't work for you, there's nothing I can do.
[Miscellaneous Android Development] Jejich.Jasnost:
The phone looks quite solid and elegant. Everything work just fine and this ROM is perfect. Wifi, bluetooth, data connection, no problem at all. No lags and it's perfect stable in my case. After full day of hard using in work and at home (in car through bluetooth) aprox. 17 hours, I still have 15% of battery. That's perfect with this 5" display and 2500mAh batt.capacity.
[Miscellaneous Android Development] ulvergr:
I must add that the phone has very good camera!!
[Miscellaneous Android Development] _mfm_:
Does the ZTE V987 have anti fingerprint coating on the display?
[Miscellaneous Android Development] alexw801:
Camera of V987

The camera is really excellent. Stock camera app works smoothly. But Camera FV-5 app (which I like because of the saved RAW file format) stops regularly, and Paper Camera app is not compatible, it freezes the phone and battery pulling out is necessary - I uninstalled this app.

The picture quality in good lighting level is the same as for example at my Leica Vario-Elmar lens on my LUMIX SZ7 compact camera (except the 8 Mp instead of 14 Mp), it is about 35 mm focus equivalent, 2.4 F-stop. At lower lighting the details are not so good. But for short distance the flash LED works well.

The saved video quality is also like the LUMIX SZ7, very good.

[Miscellaneous Android Development] bgcngm:
Sorry, but I won't suggest anything. Moreover, most probably you are already using my custom ROM, just renamed... :rolleyes:
[Miscellaneous Android Development] ulvergr:
yes but i found the solution in a older bruno's answer:

''It is very important to make sure that you click "Download" first before you connect the device. Actually there is a trick, below the sp flash tool, you will see something that says "USB". Click "Download" and wait for the "USB" to become "Searching". Once it is "searching" then connect the USB. SP-Flashtool should be able to capture it before it disconnects itself again''
[Miscellaneous Android Development] alexw801:
I fully agree with it, I hold the phone without battery all time, and only after the green circle + O.K. I put the battery into the phone.

Just received the phone, installed BROM ;) 1.0 + disable internal sdcard.

Everything works fine. No problem with CID. The only thing whitch is missing for me it is the absence of task switcher/killer (when you hold the home button).

Great work, awaiting 4.2.1! :)
[Miscellaneous Android Development] Ouzo:
Hi, I'm thinking of buying this phone so I'm really pleased to see someone is developing for it :)

Using this ROM, is it possible to install apps (or at least their data) to the external SD card? Would this work in conjunction with using your disable internal USB mod?
[Miscellaneous Android Development] bgcngm:
Yes, for the apps that support "move to SD" feature. ;)
[Miscellaneous Android Development] Ouzo:
Awesome, thank you. Now I just have to find one at the right price as well as work out who is the safest to buy from (never bought a device directly from China)

Thanks for your review by the way, it was very helpful indeed :)
[Miscellaneous Android Development] bgcngm:
It's more than confirmed that CID "problems" are highly dependent on the network operator, so it may be okay in some countries and not in others.

Hi Bruno,

How about this? http://xdaforums.com/showthread.php?t=2360670

Do you think is worth the effort for V4?
[Miscellaneous Android Development] bgcngm:
Not sure about that... but the mod is available as a CWM installable .zip, so you can try it yourself. Don't know what could be the side-effects for our device. Try it and provide feedback. ;)
[Miscellaneous Android Development] reglaspv:
I've already installed it.

The device seems a little faster and a little more responsive but Antutu score is around 100 points lower than before.

There are no visible problems, it doesn't seem to interfere with GravityBox and now I pay attention to the battery consumption.

One thing that I don't get it is why there is a final step (at install) in which tries to replace CWM with a stock recovery.
[Miscellaneous Android Development] ulvergr:
i have i installed this(http://xdaforums.com/showthread.php?t=2226373) it is similar script with the ''PurePerformance mod''

Can you provide more info about that modification? That is probably something that can be implemented via Xposed, that is to say in GravityBox.

Bricked my V987

Hi.

I have a very big problem!

bricked my V987 and want to restore, so please read this and help me!

I have used my V987 with 2.5 GB data partition (by meteos rom edit tool) without problems.

Yesterday I wanted to try the biggest partition option, 2.77 GB, then I wiped data but I got bootloop, tried a few roms, formatted everything, always bootloop.

Then tried alternate extended userdata mod v2 from post #4, or stock partitions (from same mod), I don't know which, but it worked fine after that.

Then made 2.5 GB data partition with meteos rom edit tool to get back to previous state, it worked but gallery and music etc. didn't see my files, but if I took a picture with camera it saved to the same directory as before, and there was all photos but gallery only saw the new ones.

I couldn't resolve this problem, so I searched in this thread and found this: http://xdaforums.com/showpost.php?p=44192033&postcount=521

I thought that after flashing this I get my phone in stock condition so everything works as normal.

So I flashed it successfully, but after trying to power on my phone, it didn't do anything.

Even now it doesn't do anything.

If I plug in the charger, the charging led doesn't even lights up, so, nothing.

I have another V987 in my family and it is working, so I tried to change batteries but no luck.

When a few weeks ago I flashed Bruno's rom I backed up NVRAM and IMEI, don't know if that matters.

Because I can't do anything with the phone, I think the only way to restore is by SP Flash Tool.

So I tried it today, drivers are installed and I tried many times with recoveries, userdata mods, etc. but none of them starts to flash.

When I click on Download, and connect the phone with out battery, it detects the phone as MTK USB Port and the red progress bar goes to 100% but then gives error: "Obtain DRAM Failed!" and if I try with preloader, it gives "Enable DRAM Failed!".

I think I bricked the phone because I flashed the file the I previously linked because it included preloader.

Bruno, and others please help me in restoring the phone.
[Miscellaneous Android Development] bgcngm:
Unfortunately, I'm afraid that you have bricked yous phone for good. When I shared preloader it was in a very special case, not to be used by regular users, as I even pointed out. At this point I don't really know what you can do. :(
[Miscellaneous Android Development] fcsabika:
Don't you have any idea?

Do you think my only option is to send it back to warranty?

Anyway, if someone helps me to resolve the problem, I am willing to pay a few $
[Miscellaneous Android Development] reglaspv:

You should be absolutely sure that all the drivers are installed and the phone is recognized correctly by SP Flash Tool. Use the other phone you have to be sure of that.

Yes the app is here.... http://d-h.st/3jJ some use it in zopo p980 and was working good.....

They say to take buck up the stock mms.apk(in any case)then overwrite with this one,click it to instal it, reboot and you are ok...but i see that the stock mms.apk is 10mb and this one 2,38mb.......hmmmmm

There is a section here in xda if you search for 'sms 160 letters'

[Miscellaneous Android Development] dakok:
It would be polite from you to tell us how you did that...
[Miscellaneous Android Development] fcsabika:

So I downloaded a lot of roms for other MT6589 devices to try to flash because I couldn't find any SP flashtool compatible roms for V987, but all gave the same error: Enable Dram fail.

Then I tried two things, after that it was working but I don't know which of the two was that solved it.

1: I thought that the battery was completely discharged, so I put my other V987 battery into it.

2: I made a backup of my other V987 with MtkDroidTools and comverted it to be flashable with Sp flashtool.

Then it started flashing without problems and worked perfectly.
[Miscellaneous Android Development] dakok:
Thanks!

[Miscellaneous Android Development] onizukao:

So, it can be a good idea for everyone make a flashable "sp tool image" as backup.

Hello everybody,

A guy from Softpedia forum (Kiario), in a dedicated topic for V987, solved the back button problem, which seems to be entirely hardware.

Steps:

- unscrew the 7 screws (page 14 - service manual)

- take apart the white middle support

- disassemble the rf cable (page 17 - service manual)

- pull off the FPC cable (slowly, carefully, after lifting the lock) (page 22 - service manual)

- very carefully, lift the sub-board at aprox. 30 degrees angle, only from the bottom side because on the top side there is a cable that goes further to the main board.

Replace the two black adhesive bands (or stick over them if it is too difficult to remove), with a better quality, (relatively thin) double-sided tape on all the length of the sub-board (yellow highlight in image).

Put everything back and the back button problem should be gone.

After the initial post, there was at least another user, who follow the steps and solved the problem.

Have fun!
