Just to confirm that my Sandisk 64Gb Micro SD card works fine with the V987. Just received and so to change the ROM to Bruno's now and get my apps on. First impressions look good.
That's great! I was willing to buy one 64GB microSD card... with your confirmation I can finally proceed with the purchase. :highfive:
Voltage upper limit at charging
As I charge the phone with the stock ZTE charger, the voltage is increasing up to 4350 mV, may be dropped to 4300 mV after. Is it safe? On all of my earlier smartphones (ZP100, V970) the limit was 4200 or 4250 mV.
What to do?

What to do?
May I ask if the 64GB card is supported in its native format (i.e. SDXC - exFAT), or did you (or the device) have to format it to FAT32 first? Thanks in advance.
Just received the phone, installed BROM1.0 + 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!
I tought the rom had that problem, but it has task switcher/killer.
The problem is the home button sensibility, try large push but in the top part of the home button(on the roof of the house) and task switcher/killer will appear.
:good:
It was formatted as Fat32 prior to being put in the phone as I copied my 32Gb card to it. I have not tried to format it yet from within the phone.
You're right. There is something wrong with the button sensivity, but anyway it works. Thanks!
No, I'm not planning to add those battery mods because the latest Android releases have the option to show battery percentage in status bar (under Settings / Battery / Battery Percentage).
I'm new happy user of V987.
ROM and everything is fine, but all backup programs (Titanium, My backup, ROM Toolbox pro) get stuck during batch backup. I try 2 sd card, complete wipe, but still same...
I thing, there is some "unstable" root. Titanium backup sometime stuck during startup asking for root rights. Other root aps have sometime problem with root asking too.

Are you trying to make a selective or a full backup? I never run into any problem using Titanium Backup (free version) using the scheduled backup feature (but only for certain apps, not a full backup).
Just check the SU app that Titanium back up has full rights granted. When it updates, you sometimes have to re-allow it to have access or it fails it's routine overnight runs. I have had this again this week, easily resolved.
Yeah, I also tried to connect a USB stick to the phone the other day and OTG support is confirmed.
Battery voltage limit
Hi Bgcngm,
As I started to check the battery voltage by a voltmeter, I have read on the back of the battery, that the charging limit is 4.35 V, so it is allowed to reach this value.
It is higher as on other phones, they try to keep the 2500 mAh capacity.

Hi all
anyone using endomondo on V987? Today I made about ~15km and endomondo reported ~240km with average speed ~190km/h. (bicycle). On the map it looks OK.
I've reported that to endomondo as well, but I guess this is not a common problem (yet?) so I don't expect quick resolution from their side.
Edit: looks like this is a common problem for MTK6589

How to enter into recovery mode:
With ZTE V987 completely turned off, press and hold VOL. UP key and turn on the phone. Keep holding both keys, wait until the splash logo appears and then release keys.
Navigation under recovery mode:
Stock recovery mode: As soon as the splash logo disappears, an image with a triangle and an Android will appear and BACK key must be pressed in order to access menu options. Navigation is made using VOLUME keys (navigate up with VOL. UP and navigate down with VOL. DOWN) and MENU key to apply the action.
Custom recovery mode: As soon as the splash logo disappears, ClockworkMod Recovery menu will appear. Navigation is made using VOLUME keys (navigate up with VOL. UP and navigate down with VOL. DOWN) and POWER key to apply the action.
How to flash custom recovery:
Download the latest ZTE V987 custom recovery and follow this MT657x flashing tutorial.
Important: Use SP Flash Tool v3.1304.0.119 or higher.
Flashing a new custom ROM via the SD card method (update.zip):
Read this guide to know more about ClockworkMod Recovery and how to flash a custom ROM.29ZTE V987 internal memory re-partition
Initial notes:- Make sure that you have a full nandroid backup of your current ROM. If not, boot into recovery mode and make one. This is very important if you want to restore userdata after internal memory is re-partitioned.
- Also make sure that you have a backup of your internal sdcard because it will be fully erased and disabled, depending on the applied modification.
Important: Use SP Flash Tool v3.1304.0.119 or higher.
Instructions:
Inital mod (fully extended userdata and no internal sdcard partition)
Warning: Use only with Android 4.1 based ROMs. Not compatible with Android 4.2 based ROMs, alternative mod should be applied instead (read bellow).
- Download the first attachment and extract the files to your computer
- Copy disable_internal_sdcard.zip (included in the attached .zip) to the external sdcard
- Shutdown the phone
- Open SP Flash Tool v3.1304.0.119 (or higher) and load the scatter file
- Flash MBR, EBR1, EBR2 and RECOVERY as shown on the next image (read flashing tutorial first):
- After flashing is complete, boot into recovery mode and format /data
- Optionally, if you want to restore previously saved userdata, go to nandroid backup / restore and restore data (advanced restore feature)
- Install disable_internal_sdcard.zip file through recovery mode
- Reboot your phone and enjoy your fully extended userdata partition
Alternative mod (2GB userdata and remaining space for internal sdcard partition)
Note: Can be used with Android 4.1 or 4.2 based ROMs. This one extends userdata partition to 2GB (stock size is 1GB) and the rest of the space remains for the internal sdcard. This was released in order to cope with some difficulties I had making the previous mod work with Android 4.2.1 based ROMs, so for that case this is in fact the only working mod.
Warning: If your phone has an Android 4.1 based custom ROM installed, already working with the initial mod and want to upgrade to a newer custom ROM, then this must be applied.
- Download the second attachment and extract the files to your computer
- Shutdown the phone
- Open SP Flash Tool v3.1304.0.119 (or higher) and load the scatter file
- Flash MBR, EBR1, EBR2 (read flashing tutorial first)
- After flashing is complete, boot into recovery mode and format /data
- Optionally, if you want to restore previously saved userdata, go to nandroid backup / restore and restore data (advanced restore feature)
- Reboot your phone and enjoy your extended userdata partition
27Frequently asked questions (FAQ)
Question: I can't install your custom ROMs. Why? What am I doing wrong?
Answer: First of all you have to flash a custom recovery into your phone and then you are able to install my custom ROMs. Read the tutorials on post #2 to know the procedures.
Question: I wanted to try one of your custom ROMs. Will I loose all my data after installing it?
Answer: It is advisable to clear all userdata when installing my custom ROM for the first time. During installation, you can choose whether or not to wipe userdata... If you are willing to do so, create a backup before ROM installation so that you are able to restore it later. The most recommended way is to use Titanium Backup to create a backup of your favorite applications.
Question: In phone specifications it's stated that it has 4 GB of eMMC, but only approximately 500 MB are available for internal storage... Can you explain me the reason for that?
Answer: The phone has indeed 4 GB of eMMC. Part of it is used by system and cache partitions, while the rest of the size is divided into internal storage (approximately 900 MB) and an internal sdcard partition (approximately 2 GB). If you find that an internal sdcard partition is useless (and have a big external sdcard), you can extend userdata partition (internal sdcard partition completely disabled). Jump into post #4 to learn how to apply that mod.
Question: How can I access hidden MediaTek engineering mode?
Answer: From phone's dialler type code *#*#3646633#*#*.
Question: I don't have this phone, but mine is also based on the same MT6589 SoC. Can I still flash your recovery and install your custom ROMs?
Answer: Even though your phone is based on the same SoC, there may be differences in other hardware components. It is not likely that recovery and ROMs will work on your phone so you may risk to brick it.
Question: Can I revert to stock ROM? If so, where can I get it from?
Answer: Sure, you can revert to stock ROM if you want. You just need to download the stock update.zip and flash it through recovery. To get a clean install, be sure to wipe all userdata first and then install the .zip. After first boot you'll even got stock recovery back. Following is the list of stock ROMs, available from official ZTE website:
Question: Is there any service manual for this phone?
Answer: Yes, here is the official link to V987 service manual.
Question: Is there any video showing how to disassemble the phone?
Answer: There should be more, but this one should give you an idea. You may also like to know that the "back button problem" can be fixed following these instructions.11So, here's a pre-release for anyone that wants to get a taste of the latest official ROM (ZTE China release ZTE-CN-9B18D-P188F04V1.1.3 / Custom build: B01). The update includes the new kernel, a new baseband modem, updated libraries and kernel modules. Only difference when compared to the latest official ROM is framework and system apps. I don't have time for a full release right now, hope you understand.
EDIT: Ohhh, forgot to mention that I have also removed the previously added tweak that disabled JIT compilation, which was highly advised as referred over here. No need to do it manually.
