Is anybody interested in a step by step guide for tightening

Is anybody interested in a step by step guide for tightening the inevitable-to-loosen sliding hinge of the Blue Angel? If so, I'd be willing to take my own BA apart(again) and take step-by-step pictures and give step-by-step instructions in the efforts of tightening the sliding hinge which gets oh-so-loose on our beloved Blue Angels.
It'll take me all of maybe 3-4 hours just so I can include all the details. I can even try to slap the text into a translator for the foreign users out there.
If anybody is interested at all, just let me know in a post or a p.m.
I'll tell you right now, when i tightened the slider of my BA, I felt like a child who just got their much anticipated Christmas present!
~Tim(Techie-Tim)

I would be very interested on a guide to tightening the slider!!!

Why not post it in wiki ??

I too would be interested. I recently lost one of the side screws so as soon as the replacements (www.pocketpctechs.com) arrive, I plan to undertake a thorough investigation and tightening of all the screws in my BA.

One more note*
I'd like to add in as well that most of the tightening of the slider of the BA requires more than just tightening the screws, much of it ivolves slight bends in the steel panels on the inside (I'll have pictures to demonstrate)
I'll have a 2-screw-removal-only for those of you who wish to not tamper with their warrenty sticker underneath their battery which covers one of the screws necessary for complete BA disassembly.
Also: For those of you willing to take your Blue Angels apart, MAKE SURE you keep track of all the screws you remove from your device, what I do is place the screws in order of when i took them out. What you could also do is make sticky notes for each set or pair of screws, numbering each sticky note with a corresponding number made in pencil on your device(Pencil will come off/rub away with normal use)
ONE MORE THING! If you wish to, you will be given instructions on how to apply a screen protector on a truly flat surface, if you happen to have done an un-satisfactory job on your first one.
If I think of anything else, I'll be sure to post it!
Cheers!
~Tim

I will be happy to see how to apply protector and detailed explaination of disassembling and reassembling the device
Thanks in advance

looking forward to it too!

two things to add:
it sounds weird, but I've successfully tightened the sliding part without taking anything apart: slide the keyboard out, then carefully apply pressure to the top and bottom of the rear of the phone while pushing down in the middle from the front side. (it sounds like an awkward motion, but it puts a little resistance on the track that the screen slides on, thus tightening it).
also, I have the harrier (cdma blueangel without gsm or wifi). simply by removing two screens on the sides of the phone are removed, my phone automatically hard resets (this has been reproduced on other harriers, and with different ROMs...

Please search the forum..I remember posting the steps to tighten and prevent the slider marks on the key board...may be MDAIII user can put it in Wiki..(sorry ...too late for me so pls search)

I wouldn't recommend doing that what was described on pictures... It looks insane. It would be better just to stick anything to this horisontal (when device is at it's cardle)bar(on display's part back), using tape. Safier IVMHO, and effect should be noticeable.

I agree, there are much easier ways to get the screen away from the slide!
Use a 'case opening tool' and prise it away from the bottom end first - there are lugs at the top holding the frame you may break using this method!
Check the wiki - there was a method in there once.

KAISER Screen tilt mod

I guess some of you may interested to mod your kaiser screen to tilt almost 90 degree, then you can use it on your car without any holder.
Here's a guidance document i pull together.
Remember, do it only on your own risk.
Enjoy!

Too scary for my taste.

Thanks! That's looks a little intimidating.
So basically is the only reason it tilts more is because the two plastic pieces are cut? What would happen if those two pieces were cut totally?
Thanks again.

A prediction...
Very cool mod, but I predict a large number of bricks on this one...
As a hardware design engineer professionally, I would have to recommend against this mod unless you are a technician and have access to the facilities.
If you are dead set on doing this mod, please take the time to prepare your environment - at the minimum, get an ESD strap and make sure you're properly grounded. Ideally, a strap and a mat are called for.
This is an ESD nightmare waiting to happen. Doing this on your kitchen table or coffee table - especially at this time of year, is literally Russian Roulette as to whether you will discharge 30K volts or so into the PCB and totally brick the device.
As a rule of thumb, if you don't know what ESD is, you probably shouldn't even consider this mod, or any other that involves opening up the device and exposing the PCB.
Just my 2 cents. Caveat Emptor, etc. etc.
Regards,
Jeff

nice..
i was thinking of something along the same thoughts, as it tilts, why have a holder!! just drive safe (as always)
exept, im still waiting for mine..

Wow! Nice Hardware mod tonychen! Just posting to register my shock and awe! Great writeup too!
@trick420: As can be seen, like Hermes, most sensitive electronics components are in a metal Faraday cage so this isn't as dangerous as it looks from an electronic standpoint. It's always a good idea to use a grounding strap however.
All those plastic tabs are gonna be a real bear to work with though. The TyTN only had a few but the Kaiser appears to be riddled with them.

I'm pretty sure everyone knows what electro-static discharge is.

so there are two bits of plastic going around the hinges that are stopping the display from tilting fully? like a tendon or do these bits of plastic go up against something to stop motion?

Yes you are right!
The ESD strap i guess is not available to most people except hardware engineers. The simplest way to discharge the static electricity is to wet your hands with a wet towel.

The plastic needs to be cut as it stop the two metal blocks to tilt up more. If you cut it totally, you still get the same result, so i don't see to much reason for doing that.

Uploaded the guide to a mirror:

This is a great GUIDE!!!!
Thanks Tonychen.
Nadavi.

Not to be a killjoy but people should be aware that the plastic strips are there to prevent over extension of the thin ribbon cables connecting the display to the body.
You may not actually part these immediately but constant over extension will cause them to fail early.
Learnt my lesson years ago on a Nokia 9210i (stop that cursing there will you!!! someone had to buy them!) Smiles.

very intimidating but too scary for me. i would rather not break my $500 dollar phones just so i can see the screen go a couple more degrees more

just done it and its ace
slight idea change tho because its next to no use haveing it at 90 degree angle unless in car, not cutting away plastic compleatly makes it a little stiffer and will only be able to make the screen angle to 90 by choice so you shudnt break anything as you wont do it all the time. just a thought.

very nice mod.
this is going to be off topic though. " is there anyway we could tighten the hinge? mine is getting loose already.

Just a thought but isnt it alot easier to rest the back underside of the phone on a small object. this will tilt it forward and make the screen visible in the same way... You could use a small velcro patch to secure it to the said object which in turn could secure to the dashboard etc in the same manner. Alot less scary to do and you wont run the risk of damaging your phone.....

Pretty cool, but idk about messing w/ the structural integrity.

I always thought ESD was a myth. I've been working on computing hardware for almost a decade, and I do take the necessary precautions when working on new/mission critical equipment. But 90% of the time I am working on refitting relatively old workstations/servers where my boss has basically told me he doesn't really care if these items make it back into active service or not, so stuff like that I always go commando on, and I've never had a single piece of equipemnt go spontaniously DOA on me while handling it. (i.e. every single item of equipment I've retired due to DOA was reported as DOA before I touched it...)
Oh, and I have a mini tesla coil in my cube... j/k

Here is my tesla, got bored a couple weeks ago and made one, its like my fifth one.

Who's daring enough to try this on the new Touch Pro 2?

Help taking apart Tytn II (Tilt)

I have an AT&T branded Kaiser (8925). I spilled a tiny amount of soda on it about a week ago and ever since then the keyboard hasn't worked. It has come to life several times, but I think there is either still moisture or maybe some sort of syrupy residue left over. I have tried following Mike Channon's instructions but I am probably being legendarily thick. I can't seem to release the locks with the plastic stick. I don't want to force or be too rough as i'm afraid of damaging the phone. Could someone please help me? I would greatly appreciate it.

http://www.pdacenter.ru/razborka/razbor_htc_kaiser/
see this, good luck

i couldn't have explained it better my self HOWEVER, you don't need to take the screws from the hinges off (they are kind of a pain to put back on) you can just slide the screen half ways after taking it apart and guide the data cable trough there.
i have taken my kaiser apart 3 times already, (don't ask)

[Q] Hardware fixes - anyone tried...

I am the proud owner of a new I9000, the b*&tard love child of 2 ebay purchases. Just wondering whether the leftover entrails are worth keeping. Specifically:
- broken USB port. I have a replacement part and looks easy enough to de/solder. Anyone tried??
- vol down button. Looks a nightmare to try to replace. Anyone tried??
- chip in screen. Not worried about it being perfect but its too deep to polish out and when you put a screen protector on it a bubble appears. Any ideas?
- chrome bezel. WOWOW didn't Samsung make it a separate element easy to replace...?? Has anyone done these successfully (first time, every time), or is there any way to make it look good? Other than hiding with a case which I have already done!
Thank you for all, any, or even no help.
H.

look at manuals and guides in My Android collections for your answers

If you're handy with a soldering iron and have a good one (not one of those fire-starting ones that plugs straight into the wall with a handle like five inches away from the tip) then the micro USB and button shouldn't be too tricky to replace. The button isn't that terribly important anyway depending on how you use your phone.
As far as the screen chip, I'd be tempted to use one of the screen protector methods using alcohol, perhaps the alcohol would fill the gap and stay there? Probably wouldn't work, but it might be worth a try.
I replaced the chrome bezel with a cheap, crappy gold one from china (and a gold battery cover) and it's totally pimp. The bezel is actually the very last piece in the phone though. You have to take EVERYTHING apart to get it out, it's a huge pain. I ended up slipping with a knife while I was doing it and cutting the vibrator off so I spent a few weeks waiting for the replacement touch button/vibrator/microphone board to come in.

Nexus 7 2012 fix touchscreen issues / grounding issue / ghost touches - HARDWARE FIX

OK, I have found the issue that causes the touchscreen ghost touches, unresponsive touchscreen, etc. This guide is short and simple, and is provided with NO WARRANTY, TO BE FOLLOWED AT YOUR OWN RISK. This guide requires that you open your device WHICH VOIDS THE WARRANTY. Those of us with the original grouper/WiFi/2012 version are well outside our warranties, so that really doesn't matter now.
To explain, our devices use (to my knowledge) an actively driven capacitive touchscreen sensor. It has been narrowed down that a significant number of devices suffer from a grounding issue where the voltage potentials between the case and screen will cause a number of touchscreen issues when the device is electrically insulated from the person touching the screen. There are many YouTube videos and guides on how to diagnose if your touchscreen has this issue; I will not detail those here. To be simple, if you set your device on an insulated surface like a wood table and touch the screen with ONE HAND while not touching the device with your other hand, the touchscreen will go ape**** on you.
For those of us suffering these issues, it can ruin the entire experience of the tablet. I have deduced through a logical process the location and cause of this issue, which I will detail in the guide below.
The nexus 7 uses a filmed metal back, which is mechanically grounded to the motherboard via two "blind" gold spring contacts on the motherboard which touch the filmed metal backing of the case back. I call these "blind" contacts because there is no corresponding electrical contact for them to sit upon, simply the material of the case itself is what they contact when the case is closed.
What you will do by following this guide, is physically break these tabs off the motherboard, thereby breaking the circuit of the faulty ground point. The reasons this is successful in resolving the touchscreen issue appear to be twofold; first the ground points wear off the filmed metal of the back QUICKLY due to flexion of the plastic case back and therefore end up forming a SECOND capacitor on the device case back. This causes electrical potential to build between the plastic case back and the device itself, causing unreliable reading and operation of the capacitive touchscreen. Second, the intermittent ground connection causes unreliable grounding of this capacitive potential, which is worse than no ground at all in the respect of a capacitive coupling of the case back and the device.
These issues could not and cannot be resolved by a firmware flash, because it is a physical problem. Asus could not resolve the issue completely, because even if all components involved are replaced the issue will arise again due to the way the device is constructed. It was simply a poor design.
So, to get to the meat and potatoes of the fix;
1.) Pop the back off your nexus 7. Locate and REMOVE THE BATTERY CONNECTOR to prevent any possibility of a short while you follow the rest of the guide.
2.) Locate the two blind gold spring pins on the bottom right corner as circled in red on my attached picture. Note how they do not have any corresponding connection on the case back as the WiFi GPS Bluetooth and NFC antennas do. This is because these points were meant to found the case back to prevent exactly the issues we are seeing. However due to poor design they have become the CAUSE of the issue.
3.) Most simple step: break BOTH connectors completely off the board by gently bending them back and forth until they snap cleanly off the board. There is no chance of trace damage when doing this - the solder is MUCH stronger than the super thin spring connectors and they will easily break cleanly at the solder joint. If you do not break BOTH off, the touchscreen will get WORSE because you have simply enhanced the ability of the case back to form a capacitive coupling with the case back. So break both, or do not bother.
4.) Replace the battery connector and case back, ensuring you do NOT damage any of the other fragile gold spring connections, if you do you will lose some of your antennas and these connectors are a pain in the ass to replace.
I have attached a picture that shows the two points that need broken off the board circled in RED.
That's it, you're done. Reboot the device and enjoy a touchscreen that actually ****ing works. You're welcome.
Again this guide is provided at your own risk, I am not responsible for anyone who breaks the wrong connector despite my detailed guide, and I am not responsible for any other damage your fat fingers might cause while dicking around inside a sensitive electronic device.
I understand if some are too squeamish to attempt this guide, but I respectfully request that those afraid to attempt do not bother ****ting up the thread with useless posts. Constructive comments are always welcomed.
If this works for you as it did for me (I.E. perfectly) please hit the THANKS button!
I'm also currently unemployed, so if I've helped you and you are better off than I am then donations to my google wallet account are HUGELY APPRECIATED!

Once confirmed, I would ask that the mods sticky this thread.
Post reserved for future use.

And the dumb ****s at Asus tech dept. of course couldn't figure this out. Never again will I give Asus a dollar for anything.

Even if they knew exactly what to do the company is not going to allow them to "damage" devices in order to fix them. That's how Asus would see it, as damage. It is against the original, albeit flawed, design.

They don't do **** to fix anything, I sent them one, a 2012 N7 and they did absolutely nothing to remedy it, re-flashed the O/s or some such crap. I came up with a partial fix myself.

Just out of curiosity, have you done my fix and can you post confirmation so we can get the mods to sticky this thread?
As much as I'd love to get everyone's old n7 for dirt cheap when they think its "broken", I'd also like to see us snub Asus with our own permanent real fix as opposed to their bs runaround they pull until the warranty is up.
So please do confirm if possible.

Hi, Just replaced a broken screen few days on it with a new one and got lots of ghost touches and non responsive spots.
So I tried your suggestion and it works for me , I took a less destructive approach and just put some tiny pieces of duct tape on the back cover where the connectors touch it instead of breaking them off.
My new screen is in place and working properly :good: .
Thanks.

Mods please make this a sticky thread at your convenience, I believe this info will help a large number of N7 users, and it seems like according to the user above that it works when done in a non destructive way as well.

I ve had the same problem with my touch screen, it only happened when i connected the back cover of the nexus( i had a screen change)... so before i try to break the 2 pins i ve just put some electric isolation tape (plastic) and touch works like a charm.... thanks!!!

Be careful what kind of tape you use, some tape could make it worse.
You're welcome.

If anyone else has succeeded using this method or using tape, please post your results. I'm going to assume it hasn't harmed anyone or I'd have heard about it already.

Will attempt this tomorrow and confirm back. Using tape method.

Carried out the tape option, along with other additional fixes. Wipe cache, turn off animations, limit background processes to 3 and others. Seems to be working for me perfectly now.

It's so simple to type into google search "nexus 7 2012 touch screen problem video" you'll need to do it yourself.
Sorry.

Brilliant!
Finally I can now use my Nexus 7. At first I thought the erratic touches were due to the oil on the screen but upon replacing the screen protector, the erratic touches are still present.
Tried taping the contacts with a tape (A simple electrical tape would do), and much to my surprise, the device is usable now.

Also working for me, i just broke the pins. Much better now!
Gesendet von meinem Nexus 7 mit Tapatalk

Tested the tape/isolator option (less hardcode) in my "bad" N7 (the other works flawlessly and they were both bough day 1, maybe different revisions, not gonna open that one incase!), and the ghosting hits and touchscreen ignore problems seem to be completely gone.
Thanks a lot!!

Thanks so much for the fix, it's a new tablet now. I confirm this works by using isolator tape over the pins. Very easy fix, took me 2 mins to do it... would have liked to know about it sooner

Thanks, I already had managed to solve partially the problem placing an aluminium foil into the tablet (risky and complicated so didn't posted), but this is easier and WiFi reception is better too. Anyway it is not perfect yet, same problem than my solution: try crossing axis vertically or horizontally (only one hand, tablet on a table) and weird things happen like no touch detected, very fast touchs, etc... I will post here if I figure out something else.
