[7" Kindle Fire HD Q&A, Help & Troubleshooting] Jaybone073:
I stand corrected. There is no external slot. I was mistaking the back logo panel as a possible external storage cover. My son has had the device for quite some time and he asked dad (me) to give it the "works". The device was running atrocious and much slower than it does now. I've had it for about 2 months and after installing the 2nd bootloader, rooting, twrp recovery..... You get the idea, I had it very stable and clean. It's been running quite well on 12.1 and I am pleased to see development still happening for such an older device.

As far as apps go, I have only installed what he likes. A few games (about 4) and a couple of social ones like Instagram and facebook for him. The real slowdown was actually with Facebook continually not updating and having errors. A recent reboot has fixed that. It also appears that the occasional reboot is actually helping the rom settle in.

I had previously tried the CyanDelta Updater on the play store and it didn't work well. I will now give CM Downloader a try to see of that keeps me from having to reflash the GApps and other apk that seem to force close that I had previously mentioned.

Thanks for the quick response and advice.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] monster1612:
If you go into the CM Downloader app settings, you should be able to add in the zips (maximum of 6) you want flashed after a ROM update. Once that's complete, all you need to do is download an update and initialize the install process from within the app, and it'll handle flashing the zips. From personal experience on CM nightlies for jem (the 8.9" version), I tend to see stability break down after about 24 hours of device uptime without a reboot, so reboots do help significantly. :)
[7" Kindle Fire HD Q&A, Help & Troubleshooting] Pix12:
Any progress so far?
[7" Kindle Fire HD Q&A, Help & Troubleshooting] monster1612:
Currently, the generated zips take longer than cm12.1 to flash (but they still flash successfully). As for a functional ROM, that hasn't happened yet - it refuses to boot after about 5 seconds. last_kmsg says it's an SELinux issue.

which rom has the better battery live?

[Nexus 7 Q&A, Help & Troubleshooting] rihardsk:
I had my N7 screen broken and the bezel damaged and i have had it lying around for about a year now. I finally replaced the screen and bezel on my tablet but it won't turn on any more. Looking for some info on how to troubleshoot what's the issue. What I've done so far is:

Checked that the battery seems to be fine and charged. Using a multi-meter on the battery connector gives a 4.15 V reading. The connector is properly connected (I get the same 4.15 V on the places where the battery connector socket meets the motherboard).

Changed the ribbon cable after finding out that the battery seems to not be at fault. This had no effect.

Tried to put back the old broken screen and bezel to see if maybe the new ones are damaged. Last time i used the tablet with the still broken screen it was able to power on and boot. Now after the fix using the old screen and bezel didn't work.

I have tried to hold the power button with or without holding the volume down button for various amounts of time with no effect.

As i see it now there are a couple of equally plausible things that could have gone wrong.

I have both damaged the new and old ribbon cable while changing the screens.

There is still something wrong with the power circuitry despite battery being at healthy 4.15 V.

The new bezel and screen that came from e-bay were damaged on arrival.

I have damaged something else while changing the screen.

Any ideas on how to troubleshoot any of this?
[Nexus 7 Q&A, Help & Troubleshooting] rihardsk:
Now some 24h later i'm getting 3.8 V. Which according to this http://xdaforums.com/showthread.php?t=2195070 corresponds to battery being at about 60%. Could it be that the tablet is powering on but the screen stays off due to a damaged LCD ribbon cable? Is N7 in general able to boot up with a damaged LCD ribbon cable?

I have a nubia z7 with rom version 2.05 (Android 5 and Nubia UI 3), with google apps working without problems. Even youtube.

It took 3 days to figure out how to do it, without rooting the phone.

But some tools are needed...

I upgraded my phone rom (which came with version 2.26, a modified 1.26), put rom 2.02 then 2.03 and at last 2.05, which is the last one in nubia chinese site.

I used nubia rom updater, for the roms version 2.02 and 2.03 you have to decompress to each folder and point nubia updater to that folder.

The last one (version 2.05), i used option update of the phone.

Then uninstalled every chinese app. Downloaded gapps micro for android 5.0.1 and copy to the internal storage.

Then rebooted the phone with TWRP and installed the zip file. With TWRP root the phone, in advanced menu.

After that, i reboot into android system and made login into google play and updated everything.

It's a google phone now.

I think this should work for Nubia Z7 mini and Nubia Z7 Max

I hope this help someone

I managed to get as far as upgrading firmware to v2.05. The files worked great thanks. How do I use the twrp to install gapps? Thanks for the help
[ZTE Z7, Z7 Max, Z7 Mini] S_Phoenix:
hi, i'm Senh0r. I had logged with an old account.

now you can uninstall all chinese apps ,that you don't want.

then copy file gapps to internal storage.

Check if you have port ADB selected, by inserting on dial number *#7678# , if not, select it.

Now run the TWRP, which is in chinese, when the menu show up, choose option 3 and wait for the phone reboot into TWRP.

When you enter in TWRP, on bottom of screen you can choose english language.

After that is only to install the zip file. don't check for signature.

Now it's only need to reboot phone.

To enter on TWRP you need always to run the program to reboot your phone.

Anything ask ;)

[ZTE Z7, Z7 Max, Z7 Mini] helobot:

I am a little bit lost at the start,

Some Infos on the phone

Hardware Revision: NX506JMB_B

Rooted with TowelRoot

I'd appreciate it if you guys can point me in the right direction

But after installing gapps it crashes in the setup phase

any ideas ?
[ZTE Z7, Z7 Max, Z7 Mini] Senh0r:
Did you rooted the phone before installing gapps by twrp?
[ZTE Z7, Z7 Max, Z7 Mini] vision0815:

After a few minutes it started, google setup wizard.

It crashes with an exception.

Gonna give it a shot in a few

Please have you guys an image? I am stuck for good.
[ZTE Z7, Z7 Max, Z7 Mini] Senh0r:
And cleaned the cache and dalvik partition too? Mine its working with no problems. :(
[ZTE Z7, Z7 Max, Z7 Mini] vision0815:
Cleaned cache etc.

I could hit me for being so stupid to forget backing the original ROM up.

I can easily go to a stock Chinese ROM but at least a KitKat Google ROM would be nice.

Señor or anyone, can you provide a image of 2.26?
[ZTE Z7, Z7 Max, Z7 Mini] Senh0r:
Unfortunately I didn't backup it either , :( but soon I will create a zip file with my Rom with Google apps installed.

I will check Nubia site for older roms too.

Hi Steveyknoxville, Señor shared a custom recovery based on twrp and that works very well. I would really appreciate if you could provide us with the 2.26 ROM

[ZTE Z7, Z7 Max, Z7 Mini] Steveyknoxville:
Hi, I have read that senor twrp does not work on 4.4.2, are you confirming it does. My biggest question I need answered before I do anything is, if I install twrp how do I go back to stock recovery so I can do Ota updates to get to lollipop. Thanks.
[ZTE Z7, Z7 Max, Z7 Mini] vision0815:
Sorry but I can't confirm weather it fully works or not. I followed señor's guide and updated the phone. But if I recall the thread correctly from nubia cn forums the stock ROM should be a slightly modified twrp anyways.

Try just going into the recovery mode.

You should be able to backup the ROM.

Thanks for the invested time.

[ZTE Z7, Z7 Max, Z7 Mini] iggarpe:
1- Open neoSafe application:

1.1- (probably not necessary) in "Cleaner" go to settings (upper right corner sprocket) add WhatsApp/FB/whatever to the whitelist.

1.2- In "Permission" go to "Power-on speedup" and enable autostart of WhatsApp/FB/whatever.

1.3. In "Power" go to settings (upper right corner sprocket) and either disable "Clear upon abnormal power consumption" or just add WhatsApp/FB/whatever to the whitelist.

2- In Android settings go to "Notification center" and enable all sorts of notifications for WhatsApp and other applications.

For some stupid reason the default is to not allow applications to autostart and show notifications. The "clear upon abnormal power consumption" is also pretty ****ed up IMO.

Picture this: you just installed WhatsApp and it cannot autostart nor show notifications. It will also be killed if the OS thinks it's using too much power.

Stuck at bootloop

Hi guys!

I have a problem! I just do what the first post said, i updated up to 3.88 everytings work exept i cant install TWRP from cmd because i stuck in bootloader(just nubia pic and nothing). I tried the kingroot and Flashify to install TWRP but it said successful i rebooted and now i stuck in nubia logo! pls help if there is any solution for that!
[ZTE Z7, Z7 Max, Z7 Mini] not_noober_than_me...:
I had that problem as well. I had my phone rooted with towelroot, but when ineeded to access the bootloader on v3.88 and the same thing happened, I got stuck on the nubia logo. What I did was reinstall v2.05 from the phone itself and not via external bootloader, then I got the warning com.android.phone has stopped working but that is not an issue as you can without a problem inject twrp and flash whatever you need from there (I had to do it as I forgot to flash gapps before). If you're worried about being stuck on the nubia logo, no problem there, just let the battery die, it's on a boot loop so it consumes a lot of energy so it doesn't take that long.
[ZTE Z7, Z7 Max, Z7 Mini] stanki6:
Thank you for the fast response! I managed to re-flash the whole emmc via nubia tool studio(basically unbrick the phone) and now im at 2.02 and give another shot to the update procedure! I hope this time i able to flash TWRP via cmd on 3.88.

I cant boot bootloader when i type adb reboot bootloader on cmd the phone is restart and stuck at nubia logo... im clueless what did i wrong? after update 2.05 i installed 3.88 next maybe this is the problem?

I followed what is written here

http://www.androidiani.com/forum/showthread.php?t=494770

There is a Google Drive link where you can find twrp.zip.

There are infos how to install twrp.

After installation, twrp is not working so good: I mean, it will never show up, telephone will stay in nubia logo forever when you try to access to twrp. If phone is vibrating when you press some buttons, it means twrp is probably there even if you can't see it.

From nubia app center try installing "twrp manager" (it has a round logo with twrp written inside). It can show you if twrp is installed or not.

If yes. I was able to install gapps via the nubia official updater, just selecting locale update... Phone rebooted and twrp installed gapps...

Buona fortuna

[ZTE Z7, Z7 Max, Z7 Mini] iggarpe:
When you reboot into bootloader, via volume down or via "adb reboot bootloader", all you'll see is the Nubia splash screen. That's normal. To see if your phone is in bootloader mode use "fastboot devices". If you're in linux for some reason it requires root privileges, so use "sudo fastboot devices".
[ZTE Z7, Z7 Max, Z7 Mini] seinman:
I've tried that but unfortunately fastboot does not detect a device connected.
