[Fuhu Nabi 2] SMcC2:
Well, it's finally happened. One of the kids managed to break the LCD screen on their Nabi 2.

I was not there when it happened. I don't know the exact details. The kids were at their grandparents' house, and all I got was "one of the kids threw it!" The kids have thrown, dropped, kicked their Nabis in the past.... so no, I just don't know....

There is already a thread with some pictures of a tear down of the device (see just beneath this), but it does not include any details on replacing the LCD screen and glass.

So first thing I did was remove the bumper, flip the device over, and remove the four screws in the corner of the tablet.

I then inserted a small screw driver (no place in particular) in between the two halves of the casing. If you look closely you can see the halves are held together with little clips. I unclipped the first few by working my way around with the screw driver and then was able to remove the rest by hand.

Working my way around, removing the clips I noticed that there are a couple of ribbon cables running from the LCD & digitizer to the board on the back half. Be careful not to yank on these cables as it can easily damage the connectors on the board.

The LCD panel is held in place from the rear by large plastic tabs.

I decided instead of cutting off one of the clips to remove the glass and pull the LCD panel out the front. In hindsight, it may have been a bad idea. I ended up shattering the glass into millions of tiny pieces (some of which ended up in my hand). It was then I decided to put on some protective gloves (Like these!).

The glass was held in place with double-sided tape. Not unlike many cell phones I have repaired screens on before. I used a heat gun to to make the tape more pliable and used a suction cup to pull up on the edges, but in the end no dice.... :(

Amazon has replacement LCD panels listed for around $35 as well as Digitizer/Glass sets for the same price.... If I make the purchase and do the repair I'll be sure to update this thread,
[Fuhu Nabi 2] katinatez:
Sorry to hear about your luck, nice thread to bookmark. Can you provide link to screen replacement?
[Fuhu Nabi 2] SMcC2:
Looking at ordering something like these.

NABI 2 Digitizer/Glass Set

NABI 2 LCD Panel
[Fuhu Nabi 2] katinatez:
Nice find did not know they sold it seperately.
[Fuhu Nabi 2] SMcC2:
Ordered the parts from the links in the previous post. The LCD works great, but unfortunately the Glass/Digitizer was DOA. I even hooked up the old one just to try and do a little trouble shooting and was actually able to get swipe to unlock and hit a few icons, whereas on the new one I got nothing. I have already RMA'd the glass and gotten a refund, so no complaints there. I ordered a new Glass/Digitizer from a seller in China a week ago, last I checked it was in San Francisco. I still plan on letting every one know how it goes.
[Fuhu Nabi 2] rex.torres:
I feel for you man, pulling out the glass on this thing was quite an arduous task.

The right ride, and bottom completely disintegrated in my hands up until the glue finally started giving out on me. Although, i spent more time cleaning up the left over glue than anything else.

I bought the same digitizer a month ago from the same seller listed, but due to scheduling conflicts with the owner of the tablet, I was not able to install it until tonight. Lo and behold, the part was DOA, and it's looking like I might have to eat the cost because of return policies. Such is life, I guess. I hope you have better luck than I have so far.
[Fuhu Nabi 2] SMcC2:
I know this is an old thread, I tried the new digitizer with one of the other kid's NABIs and it worked just fine. I don't remember the details, but there are different sub-versions of this tablet apparently.

I wonder if anyone else ever had any success. One of these devices was left in the sun and now the LCD is bleached.
[Fuhu Nabi 2] lfhlaw:
not much luck

I've tried remove the LCD glass twice from these Nabi's and they are tricky. I used a heat gun but the adhesive their using is pretty strong and just won't give up the glass like some of the other devices I've taken apart.

Has anyone found a decent way to pull the LCD Glass away from the frame?
[Fuhu Nabi 2] rex.torres:
If you only need to replace the LCD, and not the digitizer, then you can open the unit, cut some or all of the plastic tabs behind the LCD, and remove it from the rear. It's not pretty, but the build is so tight, it shouldn't move around at all anyway. If you do need to replace the digitizer, best of luck to you buddy. That glass is a pain in the rear.

Also...
[Fuhu Nabi 2] lfhlaw:
Yup. the LCD is fine. The digitizer glass is the PITA. I tried using packing tape to keep glass bits in, but the heat gun tends to melt the tape and shrink it lol.
[Fuhu Nabi 2] rex.torres:
Heat, and a very thin piece of plastic. Small gauge guitar pick comes to mind. Once you can get it wedged in there, you'll be fine. Patience. Also, if i remember correctly, the digitizer and front glass are one unit.

It may be more practical to break it on purpose. Unfortunately, my repair was a bad LCD that was made worse by a botched glass removal, and then further worsened by the digitizer being the wrong revision for that nabi.

If you do try to remove the LCD panel from the rear, that may make it easier to wedge something in the inner frame from the rear to try to remove the glass / digitizer assembly rather than trying to wedge something from the outside at an angle..
[Galaxy Tab 3 General] odifek:
Please help! After successful downgrade from 4.4.2 to 4.1.2, my tab 3 refuses to charge while turned off. Stuck at the stage of starting to charge where you have the battery symbol and a circle inside it. Even when cable is removed it won't go unless restarted by long pressing the power button.

It charges well when powered on but not otherwise! Every other thing is working normal.

Could it be that the downgrade has tampered with the charging software.

What can I do please?
[Galaxy Tab 3 General] N00BY0815:
How did you downgrage your tab? Using Odin or a Nandroid?
[Galaxy Tab 3 General] jasonvoor1313:
Same here after downgrade back to 412 uk jb I flashed back using odin3

Same probelm even that its stuck its still charging tho
[Galaxy Tab 3 General] DigitalMD:
4.4..2 has a locked bootloader, I do not think you can revert now to 4.1.2 without issues because you will have a mis match . Your only option may be to reload 4.4.2
[Galaxy Tab 3 General] odifek:
Hmm. I'm not ready to go back to kk. I can't access internet since I only use BlueVPN to get internet which VPN is broken in kk
[Galaxy Tab 3 General] DigitalMD:
well. you are pretty much stuck then. bootloader controls charging and so, mismatched bootloader and kernel are not a good thing

Hello,

my gps has no right position i think the difference is between 25 to 50 m :mad:

Is there a tool to correct this issue ?

Thx

Nochmal in deutsch falls mein Englisch nicht so gut zu verstehen ist ;)

Mein GPS im Artemis hinkt etwa 25 bis 50 m hinterher was sehr nervig ist :(

Kennt jemand dieses Problem und weiß wie man Abhilfe schafft ?
[P3300, MDA Compact III General] spangelsaregreat:
From what I recall no civilian GPS is precisely correct.

Only Military GPS is precise to the metre.

Not sure what the exact varience is though.

Regards
[P3300, MDA Compact III General] pklein90:
i have navigation systems before the p3300 and on all when the street cross comes it brings exactly the position when it says turn left at 50m then it was correct, i believe the military difference is only 1m or lower not 50m ???

For external PC gps receiver there is a software for correct some options for the inbuild gps.

I have no glue for a in built gps.

Sorry for the English this not my normal language, i hope you can understand what i mean thanks ;)
[P3300, MDA Compact III General] zerimar:
Also, better accuracy depends on the number of satellite signals the device can get. Signal strength is weaker in the urban areas.
[P3300, MDA Compact III General] mikealder:
What software application are you using when you notice the discrepancy? I have found my Artemis GPS position to be equal to some of my other units. For example using a topographical map when out walking the unit is very good, certainly not 25 to 50 M out. It could be low signal strength and reflections off other building that is causing a problem (if in built up area)

One other consideration, how many other applications do you have running at the same time as your Nav software, your device might be struggling under load, check settings/ system tab Memory icon/ running programs and stop all before trying the nav software Mike
[P3300, MDA Compact III General] zerimar:
My device, which is still the Magician is running the ROM 1.13 with BS. Additional software which are all installed in the Storage are; Pocket Informant, Photo Contacts Pro, Resco Suit, SK Tools, TT6, WorldMate Pro, Ring tones. All TT maps (WEU, USA+Canada), voices, schemes, zip codes, POIs and IE Temporaty files are installed in a 2GB SD. What's left in available memory are Storage = 0.7 of 26.72 MB, Storage Card = 105 MB of 1935GB.

The programs that are running (being memory resident) while TT6 is active are Photo Contacts Pro and Pocket Informant. I have BT on all the time since I use a BT headset for calls while driving. TT audio is via my Seidio active car holder.
[P3300, MDA Compact III General] pklein90:
The programm ist TT6 and only jetware, and ilauncher active nothing more, the area is no big city good sight to the air.

I checkt this with tt5 and a hp2210 with bluetooth sirfIII this combination is near perfect :D
[P3300, MDA Compact III General] zerimar:
I've never used those programs. The inaccuracy might come from any of the two.
[P3300, MDA Compact III General] Samson711:
Civilian GPS is officially (from the provider of the GPS System - US Forces) something about 10 metres unexact. Of course this number can be smaller if you have more satelites "in sight" However, GPS Navigation Programs do not need accurate positions, they calculate the position on the map with old data and then extrapolate it, showing the dot where you should be now, according to your speed and heading 1 second or two seconds ago. Of course it can control its calculation because more data streams in. It is funny to see Navigationsoftware Confused, when you ride a train. It gets a signal in a certain direction, with a certain speed, so it puts the dot on the street next to the Rails, because this is the only logical position where your car can be :) so it says "turn left now" but the train goes straight. Then it searches another street you could be on. just funny ;)

But in short: GPS Software compensates missing GPS accuracy, mostly well, sometimes not so good. Try using another Software or newer map ,maybe that will fix the problem. On my MDA Compact III The Built in Receiver works just great together with TT6. Maybe there is a way to shorten the interval between two data sets. That would give the Software more information, resulting in a more accurate position. But i don't know if a program like GPS Maus can manipulate Built-In receivers that easy.

I once reprogrammed a T-Mobile Receiver with this program, so it received also NMEA data and the intervall between two data sets could be set randomly.
[P3300, MDA Compact III General] jthspace:
In the UK, the BBC send out a spoiling signal which reduces the accuracy of the GPS. It is also sent out from National stations in other Countries. I heard it was sent out with the atomic clock signal. This is to stop "undesirables" buying civilian GPS units and fitting them to military equipment and sending something directly to your letterbox - the same way a US military GPS unit can if they want to! You used to be able to buy a box that would correct the error signal, but that got stopped ages ago.

The GPS also becomes slightly more inaccurate depending on the speed you are travelling, travel under 30 mph / 50 kph and the "you have arrived" will be within a few yards/metres of the real arrival point. Travel at 70 mph / 120 kph and the "take the exit in 200 metres" is very inaccurate - maybe by a couple of hundred metres - you can work out why!

Also GPS signals are "secondary" and can be turned off at any time in the event of a military requirement - which is why you can use the signals free of charge.

Jeff
[P3300, MDA Compact III General] mikealder:
Where did you get this gem of knowledge from?

Are you confusing the selective availability that was used to degrade the GPS accuracy up to a few years ago? - The US reserve the right to switch it back on again should they need to, but under normal conditions the signal is not de-graded any longer. If you want to send something to a letterbox the Post Office offer quite a good service ;)

The issue of position inaccuracy relative to speed won't give a major difference to position - the software maybe responsible for the apparent degradation though.

As I mentioned before the US reserve the right to turn on the Selective availability (positional accuracy degradation), if they turn it off their own planes and other civ/ mil products would be useless - Mike

Static Navigation in Artemis

In Artemis is a Sirf-III-Chipset. One of the "features" of this chipset is a Parameter called "Static navigation".

This gives a more or less "static" position if the device is moving rather slow, like a pedestrian does.

Useful for car navigation because your car is not "dancing in front of the traffic light".

But it gives a more or less not accurate position when standing or moving rather slow. You need to move with 5 Km/h at least.

No tool for switching off "Static Navigation" in Artemis seems to be working. :(
[P3300, MDA Compact III General] allenf:
BBC jamming the gps signal..?

Selective Availability:

"SA works, for the most part, by intentionally dithering the clocks in the 24 satellites that make up the GPS system. The clocks are steered by an algorithm, known to the control station and military receivers and transmitted in encrypted code over the satellite signals."

[P3300, MDA Compact III General] nixonm:
The BBC does what??? I don't believe that for a moment!

The GPS signal I get on my Orbit and previously on my Fortuna Clipon has been extremely accurate, using different software Tomtom 5 & 6, pocket streets and Vito all have been down to a couple of meters at most.

I have also used in the US, Cyprus and Spain all with the same accurate results.

Yes the US can turn off civilian GPS if they wish, which is why the EU is building Galileo.
[P3300, MDA Compact III General] madcow_x2:
duh... SA has been switch off 7 years ago!

interesting to see people still talking about SA, it has been switch off since year 2000!

[Nexus 5 Q&A, Help & Troubleshooting] J.Diogo:
Hey guys.

I have a rooted, unlocked bootloader, custom "recoveryed" Nexus 5, on stock 4.4.4 and stock kernel.

My question is, when Android L comes around, what should I do to update. Doing an OTA update is probably not the best idea right? Since I am rooted and have a custom recovery. So, what would be the steps to take to update. I don´t mind loosing root or making a fresh install.

Anyway just a noob question about something that I never had to do, since I rooted it on 4.4.4.

Thanks for your attention.
[Nexus 5 Q&A, Help & Troubleshooting] jayRokk:
Flash a factory image.
[Nexus 5 Q&A, Help & Troubleshooting] J.Diogo:
Where can I get those?
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
On the Google site. Google "nexus factory images"
[Nexus 5 Q&A, Help & Troubleshooting] tevil:
You can OTA update fine. It will just remove root is all.

Get the wugfresh toolbox and reinstall root after. This is what I do every time.
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
Don't use toolkits.
[Nexus 5 Q&A, Help & Troubleshooting] tevil:
why Ive been using the wugfresh forever now. On my nexus 5 and 7 with no issues.
[Nexus 5 Q&A, Help & Troubleshooting] PsychDrummer:
I've been away from the Nexus 5 forum for a while, I come back and this is still happening. Please don't recommend rootkits for people who are clearly new to android modification. As said a million times on these forums, rootkits are fine if you know what you're doing but not for beginners. Beginners need to do things manually because they need to be able to fix their own mistakes if they're simple. Instead of going back here and asking very basic questions which they could have answered themselves if they didn't use a rootkit.

OP: Please do as [MENTION=2872010]rootSU[/MENTION] said and flash a factory image. His sig contains all the threads and information you need. It's a very handy tool which can fix your phone's software problems in almost any situation. Especially in the case of Android L (an update with HUGE internal changes), I highly recommend flashing factory image. This is what I will be doing. The factory image completely replaces your OS with stock.
[Nexus 5 Q&A, Help & Troubleshooting] tevil:
Okay but thats a fine answer over "dont use rootkits"

That made me think they were bad or something.

Technically like myself he is all stock he said, so aside root hes already pretty much stock OS.

Not sure where the animosity is. Also he obviously knows how to root and install custom Bls if hes done it before.

I very rarely pop in here anymore myself unless there is a major issue but doing things the way Ive been has pretty much eliminated those (jinx). Im still more on the Nexus S forum since I tinker with that more as my mp3 player.

He could always just take a backup before updating and dive in. Ive done that in the past with fine results.

Also even IF you do everything manually first and down the line screw up something theres a pretty BIG chance youll be here asking wtf happened. It happens to the best of us at one point or another.
[Nexus 5 Q&A, Help & Troubleshooting] Zepius:
they are bad if you dont know what you're doing

the animosity comes in to play when you read the forums daily and you see threads saying "HELP i tried to use such and such toolkit and now my phone doesnt work"
[Nexus 5 Q&A, Help & Troubleshooting] PsychDrummer:
Yeah, but that's why we ask people to read all the threads before starting to mess with the device first. If you understand how the basic things work and what you're actually doing to achieve root, it's alot easier to troubleshoot very basic problems yourself. Of course for bigger issues people can feel free to post and get help. Also, if they did read everything and still messed up, when they post they're able to list the steps they've taken in the post so people can help them better. Otherwise, it becomes "help I messed up, I don't know what to do, I pressed the start button on the toolkit and my phone doesn't turn on."

Regarding the first part of your post, I still think it's just better to start fresh. Yeah, you can do a backup and try it but I honestly think it will be wasting time. It's always good to start fresh once in a while even if you don't use xposed/rooted apps. Eventually, your phone gets cluttered with apps and sometimes they conflict and you have battery issues, and other issues, etc. Since L is the biggest update to android since even I've been involved in it (I only started getting involved in XDA around 4.0), I would highly recommend everyone flashes the factory image and starts fresh. That way you will also know if there are bugs with L itself, or if's the fact that you installed on top of kitkat and all your prior data that's causing the issue. Anyway, no hard feelings. You said you don't spend a lot of time here so it's understandable.
[Nexus 5 Q&A, Help & Troubleshooting] tevil:
Well my bad, Ive never seen that. But toolkits (mainly this one) have very detailed instructions. Let alone the same issues happen when using ADB and push.

Its a double edged sword. I get the , go the long route first, which even I did (but also pre root kits), but In my own defense reading the OP he already did root and BL his phone (to my assumptions) so I didnt think my input was that bad.

---------- Post added at 04:49 PM ---------- Previous post was at 04:47 PM ----------

I hear ya.

I ran the L beta a while so honestly Im not that worried. JINX, Im sure you will be answering my HELP thread in 4 weeks! lol
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
There was no animosity from me. I simply said "don't use toolkits" and that was for good reasons which have been well written in the (General) sticky threads that all new users should read

The problem is we have to waste our time trying to explain what fastboot is to someone who broke their phone after only having used a toolkit. This is why we prefer people don't use them or recommend them.

On top of that,many toolkits are multi-device and this can cause bricks when faced with uneducated users.
[Nexus 5 Q&A, Help & Troubleshooting] J.Diogo:
Yhea. I also remember, when I was first serching for ways to root the Nexus 5 on stock 4.4.4, I saw many warnings saying to not use toolkits.

I ended up usung CF-Auto-Root, wich is not a toolkit right? :-/
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
Its not but it still sort of removes some of the manual steps we hope you would learn doing it all manually.

Best place to start is the general sticky thread. My adb and fastboot thread is designed to be a good start for people looking for basic info. Then anyone looking to actually root can move on to the rooting guides which employ much of what was learned in the former thread.
[Nexus 5 Q&A, Help & Troubleshooting] J.Diogo:
Right. I was checking the guide from the thread in your signature and saw the way you did the root. I've done the fastboot and bootloader unlock and all those thing, but when I got to the root part I used the CF-Auto-Root. Is this going to give me problems?
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
No no. As a root method it works fine. Just not as an educational piece
[Nexus 5 Q&A, Help & Troubleshooting] larwindcunha:
[MENTION=2872010]rootSU[/MENTION] your point being? I mean, isn't rooting with the CF Auto Root easier.
[Nexus 5 Q&A, Help & Troubleshooting] Zepius:
you clearly didnt read.
[Nexus 5 Q&A, Help & Troubleshooting] tevil:
good god look what I started lol.
[Nexus 5 Q&A, Help & Troubleshooting] piperx:
Lol, that's the way it is nowadays. :)
[Nexus 5 Q&A, Help & Troubleshooting] paintdrinkinpete:
I am new to the idea of manipulating the Android world myself(4.x-ish) and a brick was the motivation learn the long hand methods and to begin learning Linux. (Loving me some Kali). I never asked question one and now I have multiple legacy devices doing some pretty cool things. I say jump in and break something, then learn yourself to fix it with them fancy interwebbernets ... Lastly, one's question IS stupid if they have not exhausted all other resources and followed every lead first. You are holding the world's knowledge in your hand, user.
[Nexus 5 Q&A, Help & Troubleshooting] :
I don't get it. Unlocking, flashing recovery and Rooting with fastboot take all of 4 minutes.

Then you are setup to use fastboot in the future, which people like us almost always need eventually.

The toolkits learn you nothing and have and will always cause issues for some. Using fastboot properly rarely will cause any issues.

I think that's the bottom line in this debate. ?
[Nexus 5 Q&A, Help & Troubleshooting] J.Diogo:
Alright guys. Just one last question.

When installing the Android L with the factory image. Do I flash it via fastboot or TWR(custom recovery)?
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
Factory images can only* be installed via fastboot. If its a flashable zip, its not a factory image.

*actually there are some apps that can flash images too but that's a different story, I'm only mentioning this because if I don't, some smart-arse will correct me later :)
[Nexus 5 Q&A, Help & Troubleshooting] J.Diogo:
And after flashing Android L will the custom recovery keep working, or is it compatible only with KitKat?
