Halp - TYTNII Sim door unlocked pop up (sim door is locked)

So here it is:
I dropped my Tytn in the h2o.
ripped the batter out as soon as I fished it out of the toilet bowl
let it dry for about 24-30 hrs
turned it on and she was a live - BUT - it's giving me this damn pop up where
"the sim door is unlocked, lock it or i'll turn off"
so what do you guys think? I'm no expert - but I'm quite familiar with ROM flashing etc. My tytn is deff not stock.
I figure give it sim unlock - I'm not 100% sure - so b4 i go tinkering I'm seeking some sound advice
**please keep this thread clean**
Thank you in advance!

There is a tiny little switch under the door where you slide the SIM card in. This is the SIM door lock message you are getting. You may have gotten a tiny bit of water in the microswitch. Try taking the kaiser apart again, and soak just the board with the switch in a bit of alcohol. It might clean the contacts enough for the switch to make contact again.
Good luck!
Hope this helps !

Thank you for your response - I much appriciate the time you took to assess my problem. I have decided to leave evasive measures as a later option. 1st I'd verymuch like to see if a software based approach is plausible.
please share your insight.

Why do you expect a software approach to remedy what is a physical hardware problem? If you're not skilled to take it apart and fix it for yourself (the warranty would have already gone out of the window because the water indicator stickers would have turned pink), then you can pay someone who is, to do it for you. Just as washing a car wont fix an engine that wont start, doing anything with the software won't fix a water damaged phone, only dismantling it, cleaning it thoroughly using the correct products (and pyraxiate's suggestion of alcohol doesn't mean dunking it in a pint but using a specialist electronics component cleaner composed of a different type of alcohol) and then reassembling (replacing any parts that need replacing) will work.
If you don't do this right away, there's a significant possibility of corrosion setting in and causing irreparable damage so you need to act decisively.

X 2 on Flying Kiwi advise...

I had the same problem, but with a slight defference, my phone did not go swimming. The only thing that fixed it was a new one . Lucky me warranty had to cover the replacemente.

Thank you flying kiwi & all those who have adv me. - I appreciate your comments and criticism.
now for my comments and criticism: a simple not plausible would suffice. indeed I am guilty of being too ideal - regrettably a genuine yet flawed trait of mine.
the analogy of the car washing is a conflicting juxtaposition of the very task I must undertake - I indeed need to wash the engine to get her to start up again (well I hope that's all I must do)
my questions are a reflection of the fact that I am a mere dilettante of hardware. since I am an above-average-user of the software, I merely wished to approach it in a way I know best - purely a preference - albeit improbable - as I am now aware of.
I sincerely appreciate the advice - and look forward to any further comments or criticism u may have for what I am undertaking - for me it is a bit of a daunting task - simply b/c this would be my 1st 'smart' fone to disassemble and then reassemble.
I was advised by a friend of mine that isoproponol is best for cleaning or giving it a bath. - and the very lest 40% vodka haha.
cheers

I wouldnt use vodka as it does not evaporate as fast as other cleaners. You want something that when evaporated will leave no traces behind while drying in the least amount of time ( as kiwi mentioned , an electrical contact cleaner will work nice )
Ive always cleaned using alcohol and put my devices in a rice bowl immediately afterwards leaving it there for a few days ( still taken apart of course ). Just took apart a v3 razor last week and fixed one that was washed with laundry. Happy to report 100 percent functionality .
Goodluck

Theres a nice one for taking apart a kaiser

Thanks for the tips as this helped when my phone also got wet. I used rubbing alcohol as that's all I had on hand. My little toggle switch broke off though so I had to use a needle to get the position right and that got rid of the sim card door error message.
My problem expands a bit past this though as the battery will no longer charge when the phone is in the cradle or plugged into the charger cord or computer. When I take the battery out and put it in the charger on the back of the cradle, it charges. It is a brand new battery (three days) so it's not a battery problem.
Any suggestions? The phone works fine other than that. Is this something that I'm going to need to send it in for repairs to fix or does anyone have an idea on how to correct the problem??

Replacement LCD

Hi everyone,
I replaced my LCD screen and digitizer at the weekend and am now having a few problems. The battery is draining really quickly, in about 30mins. Could this be due to a non oem screen or something? (got mine off ebay)
I am also having a few issues with the power button, there was a small amount of tape in place but im unsure if this should go below the switch or above. To prevent the circuit board switch from shorting or something?
Any help appreciated.

how much did you paid for digitizer?

well I got an LCD with digitizer attached for $43

I'm needing the same, how difficult was it to put back together,
taking it apart isnt a problem but theres that many parts I'm not sure if I could put it back together correctly

Can you tell me how many different variants of the LCD are used in the Diamond? or there is just ONE LCD w/ digitizer..? And from where can I get them for a good price?

Well to be honest, I have only had problems since I changed mine and the phone is now unusable. Its quite easy to put back together, but it seems really easy to create shorts that cause problems and I think the quality of the LCD I bought is far below that of standard and is using lots of power.
Have ordered another screen from somewhere else and will try that but think I will get a leo next week as then im due an upgrade
Would still appreciate some help with my original questions?

I bought on ebay both/LCD+touch screen/. Price is fine 36US dollars. When you buy only on of this you have problem with right connection between LCD and touch screen. Picture have little contrast but not tragically. Battery draining is same. Touch screen is more sensitive than original.

Maybe is problem with correct connect gps antenna to connector on board.

To update this I bought a new screen with digitizer from a US company and replaced the board that connects to the microphone and now more Diamond is as good as new.
Screen is as original and excellent quality

Hi,
screen is original.
what happened was, i enabled win mobile autolock, and then i kinda had a fit. It was turning the screen on and off for about 1 second each time, i thought it would stop so i waited about 40 seconds, then hit the reset button.
when the phone reset it still had an "imprint" of the windows mobile lock screen on the screen, as if it had "burnt" all the white areas onto the screen.
I tryed to screenshot it, but it didnt show in a screenshot so i presumed the screen was wrecked.
I have left my phone without battery overnight and it SEEMS to have sorted itself out, but im not sure!
Thanks in advance

Thought this was fixed but the battery drainage is still huge. The phone is now constantly hot, so have stopped using it. I have dismantled the phone countless times now as I thought there may be a short circuit but with no fix.
When I posted originally the battery was on 85% after 4 hours but then the next time I turned the screen on it was on 1%.
Its annoying as I loved my Diamond but now I just feel angry when I see it on my desk. Using an old moto flip phone at the moment which I hate, untill some shops get the leo back in stock. Tempted by the n900 also, any thoughts?

Hi,
I will change my Diamond's screen. Did you buy it online? If so, would you please send a link of the LCD w/ Digitizer that you bought. Thanks in advance

R.I.P My TyTN

Its served me well for the past year but now i fear it has gone kaput..
2 days ago i noticed my homescreen had "no service" listed.
strange as i normally receive a 3g signal fine in my area with no loss..
So i figured take the sim out,
give it a clean and pop it back in
That came the same thing,
"no service"
So i took that sim out and tried my others [o2/tmobile and lebara]
Same thing, wouldn't get a signal..
==
So afraid to say this thing may end up on ebay or in the free ads as a faulty/repair handset as im lost with what to do.. >__<
Any advice guys?
[EDIT]
Yes the phone was unlocked,
must've been through atleast 14 different roms over time but that shouldnt effect this surely.. o__O

Have you tried a hard reset or reflash?
If your phone still dead..when there's a dead body...commonly there's always an autopsy . It can be hardware (antena), maybe something is loose in there.

Try hard-reset if not working flash stock and see if disabling 3G helps... Check no problems carrier side.
As Mr Clown said genrally a way to fix you just have to try every scenario and if not then might be hardware @ which point you can decide if worth the time/outlay?

Thanks guys for the info,
@MrClown I have tried a had reset to only end up in the same situation,
I will attempt a stock rom flash tonight to see if that helps
@Stylez Again i will try a stock flash and see if it helps,
Found a good one on the wiki so that should help
My guess is hardware related as the phone had been dropped a few times in the house albeit over many months not repeatedly,
I'll report back later guys
so thanks for the advice

hey dude! all is not lost! this is a common problem with the kaiser due to the sliding mechanism, i.e. "moving parts". over time, the wear and tear often causes the "main flex cable" to become loose/faulty. i had the same problem at the beginning of may 2010...had it fixed in 1 week and it worked fine. then i got an HD2 in june 2010 but the kaiser still works just fine!
i had made up my mind that the kaiser needed to be replaced the day it went bad. BUT i did not give up hope on it and decided to have it repaired because it is worth more in the second hand market with working phone functionality. did a simple cost-benefit analysis and figured i'd have it repaired AND get an HD2.
wouldn't you know it, i ended up GIVING the kaiser to my brother...had i sold it to a potential buyer, i'm certain it would be worth more if the phone parts work.
...and just to summarize! HD2 is GREAT! but i really miss the hardware keyboard of the kaiser and the super duper redundancy the kaiser had in terms of buttons...D-PAD+jog wheel+arrow keys on hardware keyboard, THREE OK buttons...count them! TWO start menu buttons. oh and the HD2 has a soft reset button in a REEAAAAAALLLLLLYYYYY difficult to access area behind the battery cover, unlike the kaiser's super friendly poke-the-stylus-in-the-hole approach. BUT i highly recommend the HD2 if you still fancy windows mobile...fast, HHUUUUUUGGGEEEE screen, and it seems android just might happen soon on the HD2.

Well if you'll care to enlighten me on where i could get this repair done id be most glad,
Wont be handing it to the people in my local market to fiddle with as i dont trust them at all
As in regards to the previous two guys a stock rom didnt help at all it still refuses to get a signal,
so its definatly something to do with this "flex cable"
But in regards to the HD i wont be getting one,
Most likely i'll be getting another xda exec [htc universal] for my social needs,
I have a tendancy of using dated hardware and pushing their limits

sure dude! i'm just going to post links here of THREE other threads about this issue (so you can verify with some more testing if the flex cable is really the actual issue), in which i have contributed my experience. you can read my posts there as well as all the other very helpful posts of other members.
http://forum.xda-developers.com/showthread.php?t=515264
http://forum.xda-developers.com/showthread.php?t=692530
http://forum.xda-developers.com/showthread.php?t=620069
summary: first try some of the debugging techniques mentioned in the above threads and look for signs that the flex cable is indeed faulty. if so, you have 2 options:
1. get a do-it-yourself kit (available on many websites and also on ebay) and errrr do it yourself!
2. have someone reliable and experienced with such repairs carry out the repair.
i had to go for option 2. and i had to rely on the parts that the service repair guy had to offer (he cannibalized the flex cable from a tilt so the front camera of my tytn2 is no longer detected!).
i totally understand the need to milk out every last drop from these expensive devices. i truly respect the tytn2 even though it is an old device. that little bugger still has so much potential. hope this helps!

Ahhh much thanks for the information man,
You have no idea how appreciative i am
Its definatly a hardware issue so its gonna have to be a replacement fixup for myself,
Looking into this listing on ebay:
http://cgi.ebay.com/HTC-TyTN-II-P4550-Kaiser-Flex-Sim-Card-Slot-Repair-Part-/290442707411?cmd=ViewItem&pt=PDA_Accessories&hash=item439fbc01d3
Essentially from hong kong as usual but that looks like it would do the job,
The only problem now is that i have ZERO experience with mobile based mainboards and hardware changing,
Give me a pc or mac anyday and ill be done in seconds but im afraid im blank for mobile operations,
Would any UK members be able to give advice as to somewhere i could get this fitted?
Only option i can think of is at the carphone warehouse..
as in my first post i dont really wish to give this to the market people for a botched job
And much thanks to ASCIIker for all the helpful information,
cos id really dread getting rid of my TyTN II >_<

I've ruined my device....is there anything that can be done?

Even worse, its a MDA Compact V.
Basically, I got the newton rings issue a few months ago and after reading threads on here, tried the duct tape trick which worked a treat....for about a month.
Then the issue came back of the screen not responding, so I continually used the tape to fix the screen. It got to the point where I had done it that many times, I was having to carry a roll of tape around with me, and the front of the front facia began to lift on the left hand side of the phone each time I did it.
It got to the point where I didnt need the tape anymore, I could just use my fingernail to pull the layers apart which would make the screen respond again.
However, recently I noticed a spec of dust under the screen. I put up with it for a while but last week I decided to try and get it out.
I stupidly lifted the layers apart and blew into the phone. This caused the touchscreen to behave very erratically and did not move the dust.
I was a bit tipsy at the time and actually lifted the whole of the front off the phone (thinking I could clean the screen and stick the front back down) but now the phone will not respond to touch no matter what I do.
I was thinking of trying to replace the front parts myself, but as mentioned its a Compact V not a D2, so the shape of the front of the handset is slightly different and I cannot seem to find anywhere that I can order the front facia.
I've got a lock on the phone, so I cant even flash it if I wanted to sell it as 'broken'
Can anyone think of ANYTHING that could help?
Any advice would be GREATLY appreciated!

You can flash your phone if you just put the Rom on a storage card and update it from there, and new digitizers are just 4 dollars, so just put a new one in ( or I can do it for you if you pay for the costs) I've replaced my digitizer about 3 times now... and im pretty good at it XD

i really hate to say it. but i think its just time to buy a new phone. I know money may be an issue. i dont have the cash to fork out for new phones either. but if this happened to me. i would do my best to back everything up. then just buy a cheap phone untill i saved up . i have an htc pure right now saving up for an evo 4g. I just upgraded my contract so i will have to pay full price for the evo 4g around $500.00 . unless ya can limp this one along . but from what it sounds like is its about time to bury that one ...
devices messing up does suck, im sorry..
Good Luck

Thanks guys.

Yes it is possible. When flashing from SD you don't have to use your screen in any way. Have a look in the ROM-Threads, u will find the way to flash and some great "how-to"s.

XSP spontaneously turning off

Hi guys,
I got my XSP 17 days ago and it's already giving me this weird problem. I bought it brand new (well, I got it from a possibly shady reseller in Russia, but it looked new and un-tampered, I checked it carefully ).
It worked perfectly as my main phone for about two weeks (with the official stable CM 11) when suddenly, it started switching off by itself. When it first started doing this a couple of days ago, it would shut off randomly twice or thrice a day, but today it switches off about every 5 minutes. Sometimes it doesn't even complete the boot sequence before it turns off.
The effect is just about the same as pulling the battery out. One moment you're using the phone, the next moment the screen is blank. No vibrations, no errors, no lights, nothing. It can be turned on normally and works for a short while before turning off again.
I haven't been able to isolate the problem to any single use case - it turns off with and without the SIM, with/without the SD card, on airplane mode and off, with the screen on or off.
It turns off with every combination of CM11, CM12 and stock that I tried, with stock kernel, default CM kernel, William's kernel and Tangerine kernel.
Although I don't want to admit it, it looks like it's a battery problem. Perhaps the battery lost capacity sitting around in a warehouse for two years? Either that or I was duped by the place I got it from, which seems unlikely as it was spotless in its original packing with all the plastic bits covering the screen, camera and microphone, and a warranty sticker over a screw on the back. Besides, they've given me a one-year service guarantee (it's not the official Sony warranty, though).
Mine is the C5303 model.
Has anyone had this problem? Can anyone suggest what I could do about it? It's a great phone except for this problem
Thanks for any help!
EDIT: Sorry, I forgot to mention that this does not happen when connected to a charger or a computer. Only when running on battery.

Thank you for your response, but I've already tried that, to no avail. This makes me think it's definitely a hardware problem that's related to either the battery or the charging circuit.
However, a recent experiment I tried seems to contradict this. I left the phone on CWM recovery for about 40 minutes and it didn't switch off! I even ran a backup to add strain to the battery, but no, it stayed on.
This indicates that it might not be a battery problem - a battery problem should affect the phone in recovery as well as inside the Android OS.
One major difference between CWM and Android is that Android runs the radios, while a recovery has no need to. Could it be a chance bug in the radio firmware? Is there any way to reflash the radio firmware?

actually i never saw a radio firmware to flash ......but it's not a battery problem for sure ....maybe cpu can't handle the ROM running or like you said radio don't run in cmw then it mite be the cause of the problem
but anyway it's a hardware ...since you are flashing a stock ftf via flashtool then the radio shouldn't have any problems at all !
so you need to go to service center i think to repair it ...sorry for not finding an answer or a direct solution for your problem
good luck man :good:

Thanks for your help. I think I was cheated and they deliberately sold me a faulty phone. I'm thinking of having my phone checked by an independent service center (for a price )
I have another question, if anybody can answer: what does the original guarantee sticker look like? Mine is the one in the attachment, stuck over the central screw.
I'm beginning to think that it's a fake sticker stuck by the shop that sold it to me

I don"t have this Sticker. The Sony Ericson Joint-Venture was ended Yeats before the SP came out... Looks like it is from another phone...
Anyway:
Cwm doesn't use a high current.
Because of stuff I can't explain in English, it could be possible the battery delivers enough Voltage but not enough current for booting up.
Although, it seems more likely to be a RAM error. Yeah, that can happen on phones too.
That would explain the very random behavior.
Cwm doesn't change anything in the RAM when it does nothing. That's why the error doesn't occur then.

Because of stuff I can't explain in English, it could be possible the battery delivers enough Voltage but not enough current for booting up.

AHA! Now this got me thinking. I flashed a fresh ROM without gapps, set the maximum processor clock to 384 MHz, turned down the brightness, switched off WiFi, GPS, Bluetooth, NFC, etc., and now it works perfectly fine without switching off! Looks like you're right, the battery can't produce enough current.
I can now reproduce the problem reliably by setting governor to performance @1.7GHz, turning up the brightness, switching on all the devices mentioned above and recording video. The moment I touch the button to stop recording, the extra strain caused by flushing the buffer to the memory causes the phone to switch off. Bingo! :good:
What does this mean? That the battery is weak? Or the charging circuit is wrongly cutting off the battery?
Thanks a lot for the info! Finally this thing is beginning to make sense. :highfive:

It means the battery is weak. I guess the phone itself should be fine.
When a bettery gets old, it can get a higher resistance. Yeah, batteries have a resistance too. In German it's called Innenwiderstand. Literally translated "inner resistance". It's the same effect like when your car's battery is old. Your stereo still gets its 12V, but trying to start the car will let the curcuit "die" for a few seconds.
The battery in the SP can be replaced, it's not that hard. There are some great videos on YouTube. Please don't buy a battery that is sold as original! Sony doesn't sell spare batteries for the SP. If it says original, it's used or fake.
Buy a battery from a seller who admits it is not from Sony. He is honest to you. Make sure it's a spare battery with good cells in it. Like Varta etc.

Thanks for the heads-up! I've called multiple repair centers and they've all told me they can give me original batteries. I'd better be careful, then!
Do you have any idea where I can order a good battery, or how I can identify which ones are good?
I will be in Eastern Europe next week, where it's easier to get deliveries from eBay, etc. I might even visit Germany! Any suggestions on how to find a battery are welcome.

That's the one I would buy. You see that this not-original battery is more expensive than the "fauxriginals"? There's a reason
You can buy elsewhere too. Make sure the seller has got many good ratings over a long period of time.
A few terrible ratings aren't a problem. There are always some noobs who break their spare parts and blame the seller.
E.g. on Amazon, look for many 4-star and 3 star ratings. They are real. Bought ratings are almost always 5 star ratings.
Don't buy where all ratings are 1 or 5 stars.
The capacity may differ from the original 2300mAh. 2100mAh to 2500mAh is fine. More than 2500mAh should be fake.
You can also buy on eBay where the seller admits it's a used battery in good condition.
I don't think you can buy this battery "" offline". If you do, make absolutely sure the connectors look like in the pictures in Amazon!
In Germany, there are lot Mobile Phone Shops with an Internet Café. Mostly, they are owned by Turks.
Usually, they have a good service. They can replace the battery for you for a few bucks. If you can't be served in one shop, they'll sometimes tell you where a shop is where they can help you.
Hope these information are useful

Thanks for your advice.
What do you think about this thread I bumped into? http://forum.xda-developers.com/galaxy-s2/accessories/polarcell-akku-1800mah-t1269918
Do you think there's a chance that my problem might be due to some other component other than the battery?

It's possible that it is caused by another component. We can't know. Buying a New battery is the cheapest option. I don't see another way to find out.
There are bad third party batteries too. But I trust someone who admits it's third party more. Just rely on the ratings...
Sorry, but I don't have any better advices.

Flash cm 12.1 only with gapps and supersu. Do not touch the kernel settings, dont make the phone overheat too much and try. Try to discharge the battery at 0% 2-3 times and recharge it with the stock charger and cable.

Can you install cpu z and tell us what voltage it reads when your battery si charged to 100% and disconnected from charger ?
It should be 4.2V i have my XSP for a year now and my battery reads 4.130V at 100%.

Solved!
Hi guys, I'm back from Europe.
I know it's been a really long time, but I just wanted to update the thread in case anyone else has the same problem and finds this thread.
Before leaving, I purchased a new "original" battery at a local shop (a pretty large scale distributor).
It looks identical to the battery that was already in the phone, and also identical to the batteries in all the videos I've seen on youtube. The SONY branding is covered by a thin plate of copper, but it's there, so I assume it's not fake.
It cost me 1300 RUB (~20 USD). There was a "Craftmann" branded battery also available, but it was 3x more expensive, so I didn't buy it.
Well, the phone works fine. In the past ~2 months, it hasn't turned off even once, and the battery lasts a day with decent use (~3h GPS guidance, ~1h FM transmitter, always connected to LTE, messaging and email, occasional calls), so I consider the issue solved.
Thanks to all who helped me!
