Hello
in the last few weeks i got some emails of ppl who had problems charging
their XDA's. So i decided to redo my Mod and make a few new pics.
First of all it seems like XDA Charger can't filter fluctuations in the powerline hence the fuse that is supposed to make sure your XDA wont be fried blows and you cant charge it anymore.
The fuse itself seems to be a 1.5 AMP fuse, unfortunatly i wasnt able to get one of these babies in...i could have used the 3.0 AMPs but i thought it
might be smarter to stick with the specs.
So where to get it from? Fortunatly i discovered that the same fuse is
built into the XDA twice. The second one is responsible for the extended battery pack, which i dont use. Perfect for my mod
Please DO NOT do this if you dont know anything about soldering.
I was just lucky Just call and expert...most will do it for free or charge a small fee.
@Peter Poelman : i hope you like this one better
Okay...lets start with the pics...
its upside down...lol
lucky the ones who preview
sorry for that
Before i forget...after this mod you should not use an extended battery pack anymore....i bought a 1800mAh battery from expansys.
which lasts me for 7 hours hard PDA gaming fun...
Aquasesh,
Your post will quite probably save my day as I have pluged the wrong cable in my XDA.
But I'm quite unclear on the exact order of your picture. I've seen it's been posted in reverse but I'm still confuse.
Could anyone put numbers instead of my X so that I can next search a techni guys to have him do it for me.

Tanguy
Ignore the bottom picture, then read right,left, right, left, right, left.
Where's the blown fuse?
I know it's been a while since you must have done this but how do I get the top cover off. I unscrewed the one black screw I could find and managed to get the 4-way cursor button out but I don't see how to get access to the front to do the soldering.
Thanks,
Daniel

after solder the wallaby fuse...don´t work
hi
I have solder the fuse one month ago...and works fine...now after charge in my car the wallaby stay´s off...try to solder the fuses again...but nothing.
Is my wallaby dead?
to all
better replace fuse with same value,not bigger or with wires,and check your charger,maybe voltage is too high.otherwise you'll damage your device.abnormal voltage input may fry your xda.
hi
one month ago i have solder and dont put a fuse...whne i charge in the car the led turn off and never wake up again...so may be my wallaby is dead now?
there is any thing i can do to put my wallaby work?
or i have to buy another PDA?
please help me...what can i do?
i again...nobody help me?
can i do something to solve this problem?
don't know what to say,remove battery,let him without battery some time few hours or more,search for another charged battery and try again,maybe only charging part are damaged.
i don´t have another battery...is built in...i gone try discard from wallaby few hours...
another adivece?
manythanks
Hi
I removed the battery a lot of hours...and nothing
anotther sugestion please?
Does anybody out there know what may be wrong with my wee Wallaby? The battery fuse is gone, so i've jumpered it out but despite the battery voltage being 3.5v the unit wont start at all. It doesn't respond to any reset and I cant get it to enter bootloader mode. Any info would be appreciated, i'm an electronic engineer and noticed there are quite a lot components involved in the battery circuit.
Thanks.
Buy a replacement on ebay for 10 us . LOL Upgrade your wallaby its olddddddddddd
Yeah, i've ordered one already! I was unsure though if this was going to be a waste of cash. A whole £13! I'll let you know how it works out. Thanks for the reply.
I think you have probably fried the logic on the battery. As for upgrading, I think the Wallaby is the best value pda/phone available anywhere.
Hi there,
Got my new battery and low and behold it has brought my Wee Wallby back from the grave! The battery IC's must have been faulty, there's five pins on the circuit board for the motherboard to connect to so I reckon the battery logic is quite sophisticated.
Thanks for the help guys, I tried O2 in Glasgow but they didn't want to help at all unless the XDA was a warranty job.
I've also upgraded my ROM to the one and only XDA Developers special and I have to say it's a real improvement all round.
Goodnight gadget lovers!
I dropped the phone while traveling at the airport and the power button on the top of the phone became de-soldered.
Anyway the phone was working fine until I finally powered it off to take it apart to assess the damage. If anyone is interested or has any questions please drop me an email or PM me.
I have had one person interested so far...but no commitment. If anyone is interested please make an offer...I want to get this thing off my desk
What city are you in?
im in US and need an LCD screen and battery and battery cover.
need a speaker, the one used to hear phone calls
still got it?
i would need the battery and camera cover.... and the best would be like the cover at the side which goes arround ....
do u stil have it?
please pm me if u want to sell them and tell me a price...
I could use parts of the innards...Like the usb connector.
hello, im looking for the tiny volume slider switch... I hope you didnt broke it during disassembly process (its so tiny you maybe broke it and you dont even know about it)...
please Im so desperately looking for this part
Interested in the motherboard.
would pay around $15US

I suggest, you'd better post in the correct forum ---> http://forum.xda-developers.com/forumdisplay.php?f=476
for all members of xda - developers can understand what you are offering
Long sad sad story short:
Bricked my Flyer to the point where it didn't boot up, had wrong radio roms and in the end, the battery died.. now it just blinks orange..
HTC Repairs said that the motherboard needs to be replaced, which I find very hard to believe, since it worked just "FINE" before the battery died
In my search for a Battery for the device I only came by chinese bulk sale pages, 100pcs minimum order.
Would be very grateful if anyone can point me to a page or person who can spare a full Flyer/Evo battery, or better yet, who knows how to manually charge the battery, if possible, using a power generator..
(And yes, I did a search on the forums but no clear lines of help in my question)

Thanks, ordered a new battery for 29$, will see if it works
is it orginal battery?
when you get the battery can you inform us about the new battery's performance?
there is a a post on how to manually recharge battery; search a bit XDA; Globathron posted solution for a guy with same problem.

Hi all,
I had to replace the power button flex board of my i9100, but I made a mistake when soldering, and something shorted and a SMD in the board exploded with a *BANG* and went flying like a bright shooting star. Then came the smell of fried electronics, oh boy, that was horrible! Strangely, I couldn't locate which SMD component exploded, the boards looks fine, even if carefully examined with a 10x magnifier.
I thought the board was completely destroyed. But I fixed the power flex cable soldering, assembled the phone, connected it to the USB charger, and guess what?? The recovery menu appeared, some message appeared and quickly disappeared, and the phone booted normally! Everythting worked: network, wifi, bluetooth, camera, etc. However, the power button didn't work anymore, even now it's properly soldered.
I removed the battery to turn off the phone, but now it doesn't turn on with the button. If I plug it to USB, now it shows the charging battery screen, animated and all, but I can't turn on the phone anymore!
So I ask: does anyone know which SMD components take part in turning the phone on by pressing the power button? I can't find this info in the service manual, but I'm sure it's just a matter of replacing a burnt SMD resistor, capacitor or inductor, since the phone works, I saw it working!
So, does anyone have any info for me, or at least a detailed diagram of the circuitry, so I can find my way into that?
Thank you all in advance!!!

Hola Eduardo,
you probably used a too high temperature in the soldering iron.
Google for "56542824-Samsung-GT-i9100-service-manual.pdf" and you will find a good service manual that will guide you on a series of problem.
I doubt that there's a procedure for your specific problem, but you may be able to know what SMD you have to replace.
I wish you luck, and next time make sure that the temperature is low (and eventually use a solder paste!)

Thanks for your reply, robdpi!
The soldering iron temperature was ok, I used a 12W Weller micro soldering iron, temperature was not more than 550F / 300C, and I never leave the iron on the work for more than 3 continuous seconds. The problem was a short between two of the 3 pins in the connector. I noticed it only after the accident occurred, testing with my multimeter.
About the service manual, this is the one I have, and the testing procedures (voltages, frequencies) are all OK when plugged to the USB, but they all fail when I try to turn it on with the power button. And you're right, there's no procedure in the manual regarding this specific problem.
Anyway, I will keep trying, thanks again,
Eduardo
Well, after almost an year, I fixed the phone! I'll write about the solution here, to serve as a reference to anyone who needs help.
I managed to find the electrical schematics of the whole phone. With the information given in it, I noticed the connection between the positive battery pin and the flex power button connector was interrupted. Probably the short circuit I did overheated and blew some thin trace on the PCB and it kind of exploded. So I soldered a thin wire between the battery connector and the power button to replace the lost connection, and the phone is now working again! If anyone needs the schematics, just PM me and I will send it over.
But now, I'm back to another issue the phone already had, even before I did the short circuit: the screen shows horizontal lines, blurring the image. It started after I replaced a cracked screen. Does anyone have any idea if it's software or hardware related? May it be a driver issue? I'm from Brazil, and the screen came from Korea (bought at eBay). Should a korean screen work in my phone? Is it possible to confirm or not if it's hardware or software related?
Any help will be great, thanks in advance!

I attached 8 pictures showing how the thing looks like. Please note the banding can't be seen on black background, and it's only horizontal. I used red arrows to show the banding. Vertical and curve artifacts are distortions caused by the camera.
If you pay attention to the file names (which have the time each picture was taken) it's possible to see how the thing gets worse with time. In the last pictures, screen goes completely unreadable, it degrades to an almost uniform bluish white.
I already tried flashing a custom kernel as suggested on another thread, but it didn't help. Already tried stock 4.0.4, that didn't work also.
Thanks a lot for any help.

You mean you tried the screen on two motherboards, and it shows the same problem on both? Could you please tell the country of origin of your motherboards and screen? I suspect it may be a hardware incompatibility issue.
In other words: motherboards sold in country X may not "talk" correctly to screens from country Y. My i9100 is from Brazil, but the screen came from a Korean seller at eBay.
By the way, does anyone know if the official firmwares come with low level hardware drivers? Is it possible to "transplant" the video driver from an asian firmware, to a south america firmware, for example?
I know about android phones which changed the wi-fi chip during their life cicle and this transplant used to be made, and worked. I would like to try the same for video.
Thanks!

This is either a screen problem or a battery problem.

I have only one battery, so can't swap to test. But could you explain how could the battery cause this problem?
I just measured the battery voltage with a digital multimeter, and it's 4.15 V, fully charged. This is almost a half volt above the 3.7 V it should be. Do you think this may be the cause for all the problem?
Many tthanks!
Yeah, screen might not getting enough juice.

I did another test: measured the battery voltage with the phone turned on, to check the voltage drop caused by phone load, but it seemed normal. With phone on, battery measured 3.8V approximately, which is a little less than the 4.15V I got without load. The battery indicator shows 75% battery charge. It looks like the battery is behaving well under load.
Anyway, I will try another battery as soon as I can.
Thanks again,
Eduardo
Well, I did test with another battery and the problem persists. Should I give up and consider it's really a screen hardware problem?
Thanks,
Eduardo
My guess was on the battery, I guess I'll take the screen problem then.
You should have it checked it out with a tech guy.
Sent from the little guy
Well, I think I went as far as I could. I replaced all 20 tiny SMD components from the display flex PCB with the ones from the old display, which cracked.
But it didn't work, the problem remains. Now I think the problem lies in the AMOLED screen itself, or perhaps in the main phone board. Who knows if the main board is sending dirty electrical signals to the display?
Anyway, I think I will just sell the phone the way it is, I can't afford spending even more money on this phone.
Thanks for the help, gastonw!
You got it Eduardo.
