128MB upgrade clarification - JASJAR, XDA Exec, MDA Pro Software Upgrading

I have bought a defective blueangel to harvest the memory chips, as I couldn't find a place to only buy two of them and now my uni is disassembled ready to go in along with the blueangel motherboard for the transplant. I have read the instructions in the wiki several times but the three photos are not the same. In the first photo which also displays the pins that should connected, the ram modules are not on positioned at the same place as the other two which show the motherboard on the workstation. My question is, there appear to be at least two varieties of uni motherboards. Are the pins the should be shorted the same?
Edit: My bad, the motherboard is the same, just the ram chips are not displayed in the first photo, at least not where they really are.

I wrote the 128mb upgrade page, if there is anything you need to know let me know, PM might be quicker.
The first picture is of a bare Uni PCB with 2 zooms showing where the shorting link is. The shorting link goes between the 2 square pads on the motherboard at the end of the row of 4 little brown blocks, ignore the round pads they are test points.
The other 2 pictures are of the Uni PCB with chips being soldered in to place all Uni's have the same motherboard.

Thanks for the reply, that was another point I wasn't sure about. Now it's all clear.

UNIVERSAL : need a Coaxial Cable Pre-assy replacement

Hello
I am new on this forum, sorry if this type of question has alreday been answered.
I've got a UNIVERSAL/ SPV M500 and the Coaxial Cable (linking the screen and the keyboard) has been twisted and is damaged.
Where can I find/buy a spare part to replace it ? the reference number is 73H00233-01M (Coaxial Cable Pre-assembly) as indicated in the service manual.
Thank for your help.
Hey,
If you find it let me know, I need one two. Actually these are two cables the Coaxial (Display) and Coaxial (Functional). My screen goes white in landscape mode and I confirmed it's the cable by disassembling my machine. However was unable to find that cable Will let you know if I find it.
Me too.
I am getting odd touch screen errors and think it can only be the cable.
If anyone knows of a supplier, please post here.
Has anyone tried contacting HTC directly?
I've tried HTC europe , they forwarded me to the local repair centre. this one do not sell spare parts without repairing the item.
I'm trying to contact various shops . I'll let you know if it is successful

Give this site a look, http://www.apexlaptops.co.uk/Universal.htm
I have been having the same problems as you guys. my uni have been getting "white screen of death" for about 6 months now.
I am going to take out the cable and try and fix it myself. (fingers crossed)
I will let you all know how it goes. I felt £60 plus vat and postage was a bit steep.
coax cable
Fixed it!!
I took apart my uni down to the last screw, and rebuilt it.
In the process I did find that i am missing an antenna in the back, it should have 3 but only has 2. oh well it works.
The 3rd antenna is for 3g and i am not on 3.
Anyway back to my uni.
The coax conectors where a little lose, so after a good clean in a solven cleaner and popped back in to the conector holder, after playing for 20 mins I found that they poped back out verry slightly, just enough to make the screen go white and not function.
So the solution is to make sure it does'nt come back out.
ok.
well I have as a tempery solution put a tiny bit of foam on top of the connecter and held it in place with a bit of tape.
If this works for longer than a month then i will solder the cable down.
Touch wood it seems to be working. I will try and get some photos done tonight

Hi,
Congratulations!
What tools did you use for this job(srews, tweezers)?

re: fixed it
Yes just a torex screwdriver size 6 to take out the 4 security screws in the battery tray, watch makers screwdrivers and a pair of fine point tweezers.
still having problems with my camera so photos will follow when i take it apart to solder.
ang how about antistatic gloves?

Anti Static gloves!!
Because of the Job I do, I have an earthing band to connect the phone and me to the wall, and put the phone on an anti static table cover. All is good so far. I am looking at Feb to solder (as i have some leave in). There will be detailed photos and description.
Untill then........
Just found a coax on e-bay
Hi I hope anyone who is after this coax cable can read this before the weekend is out, as there is one on e-bay for £40 this is the link.

Good done man go ahaed, and plz try to post the photos.
Another question, my universal some times lost its external speaker sound, so i cannot hear the rings, when i press on the back of the device, exactly on the battery cover in the middle between the two dummy holes and the usb port, it works again. Do u think that this is due to the coaxial damage also, even i don'y have any problem in the screen??

I have disassembled my uni and checked for all connections, but there was no improvement. I can confirm that the disappearance of external speakers sound is not due to co-axial cable. The proof is that i extracted my main borad from my uni and implanted it in another one, i assumed that the problem will be rsolved, but the same problem still exists. Ok, now i can disassemble my uni for smallest piece, but any one advise me where is th connection part or the piece that causes that problem. Again a brief description of the problem:
when there is a coming call, i cannot here the ring or it is sevrely intermitent, also when i play any WMP file, i cannot here the sound, if I press firmly on the base or around the keyboard the sound comes again and may last for a few minutes or disappear after another press. So, there is a lose part in the main board i think that needs fixation, but which one????
Hi all
Now it takes me more than a month to upgrade my JASJAR due to a lot of problems I faced during this upgrading adventure… anyway, the last problem I still have is that after upgrading the screen goes crazy, I mean if you press on the screen the colours are mixed for few seconds and then its ok but at any time I touch the screen again the same happened so you can imagine what if I am going to dial a number or write a message …. So can anyone advice me what to do? …
The rom version is 1.13.82
Radio 1.04.02
Extrom 1.13.188
And I think the bootloader 1.00 and I don’t know why I feel that the bootloader is the reason ... I made a deep search but I couldn’t find problem like mine

Sitting next to my M5000 and all of a sudden the screen turned on but was white!
Following your lead I found that the first i.e. 'underneath' connector was not fully home. A little push and all is well.
Took the time to pack out the housing for the stylus to stop the little blighter escaping whilst in there.
Thank you for taking the time to post gingerchristopher.

External wifi antenna

Hello,
i want to connect external wifi antenna to S620 and i need some small help with that.
I dismantled the phone and removed shields from all ICs.
On picture 2 and 3 are Texas Instruments WiFi chips.
On picture 1 is other side of the board, with some metal piece and connector, which might be external wifi connector.
The connector is at opposite side in left bottom corner if you look at image 2, between PASS sticker and mounting hole, at the corner of large PCB ground pole.
Is that metal piece integrated antenna?
That connector is probably not U.FL.
Anyone know what type of connector is that?
Thanks.
Not sure but follow the link below for the service manual, it may give you some insight:
http://forum.xda-developers.com/showthread.php?t=402998&highlight=service+manual
if you managed tu connect it, let us know everything...
hope you can do it succesfully!!!
Ok, so i looked at the service manual, the connector is diagnostic (RF measurement) type, with switch.
MM8430-2600RA1
Probably will be in all HTC devices. So i will try to search on the forum, if anybody done this on different phone.
See page 9 and 10 for switch schematics and pinout
http://www.murata.com/catalog/o30e8.pdf
There are "probe" cables for it, but the probe connector is too big to hide under the cover.
I have a friend with experience with SMD, so i asked him if he can desolder it and solder pigtail with RSMA.
Cable can be taken out of the phone by using free space around hole which covers the GSM antenna connector.
I verified that by putting the cable in and closing the phone.
I also tried to hold stripped cable on the connector, with attached directional antenna and i picked up the APs in that direction, so it is working. (and really well)
The problem is that ground poles of the connector maybe connects ground to the power button, so after desoldering, it might not be possible to turn it on...
The safe way can be removing that piece of metal (yes, it is wifi antenna) and solder pigtail instead of it.
It should be simple, because under it are only two "paths" in PCB.
However, the best way is probably to solder it on opposite side, there is a PCB path from Wifi chips, going through the PCB, ending on middle pin of the connector.
But that cannot be done, because there is no way how to get the cable out of the phone.
I still prefer desoldering the connector, because it is placed "before" the antenna, so connecting it there would give a bit better results.
Edit: i searched the forum a bit, but all i found is service manual for Diamond, which seems to have U.FL connector. But i will not buy it because of that, only maybe when it will cost 80 USD like S620.

Can I replace the mic? Can't find replacement on eBay...

As title says. I have a problem with my HD, that the mic falls out now and then.
Sometimes just for a few secs, but also sometimes for longer periods which make it really hard to have normal conversations.
I've searched for a replacement mic on eBay, but can't find anything. Is the mic part of a "module" that need to be changed altogether?
Really appreciate any help on this matter.
Best regards
Kristian
Yes it's on the 'upper' circuit board (attached) and beneath a small rubber cover-right next to camera-I believe you need the whole circuit board-it could just be a dirty or loose connection though and may be worth checking where the upper board connects to the main board, A broken screen/parts only phone off ebay may be the best bet to repair it. Replace the upper board.

Ummm... It isn't.
It is on the "Lower" circuit board, next to the headphone jack.
It is fixed to the mainboard and looks like a very precise and delicate procedure to replace.

*Ripped off antenna from motherboard*

Hi guys i was replacing the screen on asus zenfone 2 after cracking it and while doing so i ripped of the port on motherboard to which the antenna connects like with roots . And right now i cant use my sim cards because no antenna)))
Any thoughts how can i fix it? or where can i buy new motherboard? Maybe asus service center can fix it for money? i mean phone is ideal but no antennat for now maybe i can solder it? Will it do the trick?
Did you ripped the connector in the upper (big) or lower (small) board?

dear alex i have the same problem as yours and i know the fix, i manage to peel off the surface of the motherboard; using a thin razor blade, where the center pad is missing, the rest of it on the sides is ground, i manage to trace the track to a resistor inside of the shielding can, and i make jumper to the antenna cable and voila the signal is showing again and all working fine, if you can provide the photo of the board (remove the shielding) i can draw you the line to make the cable jumper...

I have a similar problem too and will appreciate if you could guide me on how to rather solder it inside the shielding can. I soldered it back to the original place but it is not firm and does not seem to have a solid base. I am yet to replace the screen which is damaged as a result of the phone falling off the roof of my car and being ran over by cars. I have attached a couple of pix for you to select from. Thanks.

Hello, how did you solved it?
i know that the center pad is already ripped off and nothing is left but if you see carefully under a magnifying glass, there is a small yellow dot that is the line under the center pad, use multitester to trace it to some resistor in area i have marked in red, so sorry i'm no longer in posession of this board because i have return it to my customer, and i did not make note of which resistor to jumper...
just try it yourself and post your results here, as for the antenna i cut of the connector and made a plain jumper to the ground and the other one to a resistor....

I did not understand very well , say the yellow dot that indicated by the red arrow ? the connector was previously welded where there is a red circle .
I have to cut the metal connector and leave only the black wire antenna ? Thank you so much for the reply don't worry for the late response
i only mark an area not a specific point because i don't remember the line from center pad is connected to,
antenna connector welded to board if peeled off, the surrounding is connected to ground, the missing center pad you have to see using 10x magnifying glass and you can see there is a small dot still exist, you try using multitester then to find where is that dot ends, in the area i have marked, after you find it, cut off the antenna cable at the connector, and solder the outer cable to ground and the center to the part where you have found using mulltitester..

In your photo of mother board, you use Red Arrow point a solder pad. Is the point to connected to Antenna center pad. Appreciated your reply.
Also appreciate expert can post a photo here to show found point for Antenna center point.

connector's digitizer has broken,
can you help me the solution, please ??? i have a zenfone 2 with broken connector's cable display, where i must jumper the cable display if the connector's has broken on motherboard ??? thanks a lot.
I have same issue with antenna pad on mainboard ripped off.
And I found the soldering point is actually not as the previous pic posted above.
The actual center pad connected with the antenna goes to a cap as I pointed with yellow arrow, the circuit follows by my blue lines on the pic.
Been Tested. Give a try on yours, guys.
You guys are awesome!
Made an account just to say that you are all amazing. With the info on the thread I was able to fix my phone and saved a lot of money! Its a lot easier than I thought it would be, and I'm not the greatest solderer.
Take your time scraping the traces away, and put a dab of glue on the joints to firm them up. Don't rush and take your time people!
I had a picture to post as well but xda doesn't let accounts with less than ten posts can not have outstide links sry

After typing out a mutliparagraph response and loosing it, I had to switch to my computer. I'll try to condense what I had previously typed out, I don't feel like doing all that again.
BUT after several weeks of my antenna fix I can tell you it is not perfect, least my fix isn't. Granted half reception (none inside buildings or in certain places) is better than none. But it doesn't seem to be a perfect fix. I have issues uploading anything like texts, images, etc. Downloading is unaffected. My phone is my only source of internet so I really notice this. My speed test results are looking like this: (mb/s) Down: high=29.59 Low=4.4 Up: high=2.48 low=0.13 Ping doesn't seem effected. My upload speeds used to be higher than my download... Before I even did the trace scraping fix, I emailed Asus about purchasing a Zenfone 2 motherboard from them (none on ebay/online) and they won't sell them to regular people. Super bummer, but its okay I ended up buying a new Zenfone2 (the zoom and lazer aren't worth it) it should be here today.
Got a little off topic there, but we're good. As for the fix itself?
I used a thumb tack for the scraping action, take your time and don't dig deeper than the trace! (pic below for the CORRECT trace) As for the antenna wire, Cut the end that has the broken off port still stuck in it and strip that sucker. Split the outer metal wires into two stands. Use your teeth or a lighter to expose the signal wire. Tin your fresh wires (less is more, its small pads and wires!) and turn your attention to the ground pads. They are the large pads left where the plug was sitting. At this point your trace should be visible, your antenna should be tinned, and your fingers crossed! I had forgotten to tin the trace and pads but It worked out because I tinned the wires with a tad too much solder so it was okay. But don't be like me, tin your pads and trace.
Start with the ground wires first being sure to check the length of your wires before hand, and get them on there! Once they are secured move on to the signal wire. I found this to be hard, it is by far the smallest thing I have ever worked on. Have good lighting, steady clam hands, and a magnifying glass! You don't want to break anything else here, even if you don't fix the antenna your Zenfone is a great media device! When you finally have that signal wire on, take a smoke break you need it! Next, turn on that phone and test the connection. If everything is peachy put a dab of glue on your fresh solder joints for protection. When putting the phone back together be careful not to pitch or snag any wires. Also, I cut the corner off the copper heat sink so that I would sit flush with the new fix.
Sooo ya. That's about it folks!
Good luck chorgan and may the force be with you.
I'll see any replies to this comment, so ask away if anyone has questions. I'm no expert, but I'm glad to help!

Update: I just had a look inside and was planning to solder it tomorrow so I taped everything down and while I was at it, made sure the connector was realigned with its old home on the motherboard. When I turned the phone back on, my 4G worked. So it's possible (though I wouldn't stretch to saying it's a good long term solution) to just tape the socket back on as long as you apply enough pressure that it won't move around in normal use. I'll keep you updated on how long this lasts because it could be a much easier fix for us that aren't too handy with a soldering iron

(pic below for the CORRECT trace) As for the antenna wire, Cut the end that has the broken off port still stuck in it and strip that sucker. Split the outer metal wires into two stands. Use your teeth or a lighter to expose the signal wire. Tin your fresh wires (less is more, its small pads and wires!) and turn your attention to the ground pads. They are the large pads left where the plug was sitting. At this point your trace should be visible, your antenna should be tinned, and your fingers crossed! I had forgotten to tin the trace and pads but It worked out because I tinned the wires with a tad too much solder so it was okay. But don't be like me, tin your pads and trace.
Start with the ground wires first being sure to check the length of your wires before hand, and get them on there! Once they are secured move on to the signal wire. I found this to be hard, it is by far the smallest thing I have ever worked on. Have good lighting, steady clam hands, and a magnifying glass! You don't want to break anything else here, even if you don't fix the antenna your Zenfone is a great media device! When you finally have that signal wire on, take a smoke break you need it! Next, turn on that phone and test the connection. If everything is peachy put a dab of glue on your fresh solder joints for protection. When putting the phone back together be careful not to pitch or snag any wires. Also, I cut the corner off the copper heat sink so that I would sit flush with the new fix.
Sooo ya. That's about it folks!
Good luck chorgan and may the force be with you.
I'll see any replies to this comment, so ask away if anyone has questions. I'm no expert, but I'm glad to help!

I just saw this after my post about the the tape method. Thanks very much for the reply, pity I (hopefully) won't end up using it.
I had actually misunderstood the connector, I had been thinking that the two pads for ground were the onl y two contacts, and so one must be ground and one the signal wire at the core. That would have made for some heartbreak when I turned on my "fixed" phone. Hopefully mine stays cooperative, if not it's time to bust out the iron... or just buy a portable hotspot and a blokia. Anyway, I hope your luck is better with the new ZenFone.
Ps, I think my 4G may be a bit slower? I've had one drop off off where I lost signal completely but I have a feeling it's intermittently dying but not for long enough for the phone to register the loss. I'll try a speed test soon

Mainboard connector port broken - replacement available?

It seems that I have either been too careless when changing my broken display, or I have a typical monday example from the production floor... Because the big flat cable connector mounted on the mainboard has cracked and a corner piece has broken off completely.
I managed to glue it back into place, but there's some plastic missing between the wired connection points. This means (seems to anyway) that my MicroSD slot is busted and is currently short circuiting the whole phone if any MicroSD is mounted.
Now my question:
Is there anyway to buy an entirely new one of these connector ports?
I've looked high and low online (eBay and otherwise), however I really don't know the proper terminology to search accurately.
I work in electronic manufacturing and we actually have connectors in stock, very similar to the one I need, but obviously similar doesn't cut it - I need the exact model used. If I had one I could easily solder it in place at work...
Does anyone have any ideas of how to find one?
I include one picture to clarify which connector I am talking about. It is not a pic of my actual mainboard, but a pic from eBay that I marked, just to give a general idea.
