Mirrored(reverted) screen problem - JASJAR, XDA Exec, MDA Pro Software Upgrading

Hi, i bought my universal (mda pro) on allegro (e-bay like polish portal). First time when i switched it on, screen was mirrored. I serched google for any rom to replace the original(now it is some qtek). It was useless. After next few hours on google i found pictures of dissasembling universal. I had opened screen and moved cables. When i switched it on it was ok... but only for 1 day. Right now moving cables does do nothing.
Question is: is there any reg hack to put screen to original, or i have to replace that bunch of cable from mainboard to screen or mayby it it bad soldering?
If any one has experience like that, plz help.

It was nescesery do replace lcd flex cable. I bought it from ebay from hongkong for 30$(with chineese post service) it came to me within 2 days. I replaced it myself. Now it is OK. If U know how to use screwdriver, i reccomend to do it yourself.

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

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.

Do you have made a ROM upgrade?
its your flexible.. the one who connect lcd to the motherboard of your hermes.. i had the very same problem 3 months ago. and i bought it the flexible on ebay for $50..
I had the same problem. If i push the ON/OFF button twicce, one for turn off the PDA and one to turn it on again, i can see the display OK. Orange has changed me the PDA.
Flex Cable Connector
It is the flex cable connector that goes bad. You can get a new flex cable as mentioned before on ebay (I've seen for $35)... or you can try the other fix mentioned on the link in the first reply: disassemble the phone, put a small peice of foam (similar to memory foam) over the flex cable connector, and reassemble the phone. This worked for me. It holds the connector in tighter and the screen whiteout quit. You will need a T-6 screw driver.

Flex Cable change gives errors PLEASE HELP

Hi dear developers!
I got a Touch Pro 2 from a friend, it's a GSM device he bought in Germany (O2). I changed a few parts but messed the main flex cable. The part from the power button is not connected anymore, a clean cut through, no repairs possible as far i think. So i bought a new one over ebay from Hong Kong. The seller told me it's for a GSM device BUT the cables do not look the same. The production date is 2008 and the damaged one was produced 2009. I built everything together and now the big surprise:
Phone boots normally but when the Home screen appears, it is always in landscape mode. No matter if the phone is closed or the keyboard open. I can only change the screen over advanced tools, but after soft reset again only landscape mode. The buttons for calling also do not work (those two down on the screen when you want to call someone or end a call ---> no reaction).
A hard reset and new ROM (energy) didn't change anything. By the way, the keyboard only fires up after pressing a button. Before it automatically lightened up after sliding.
What the hell is wrong now, did the send me a CDMA cable? Where is the difference ? Please help me i do not want to spent another 30 bucks again for a proper flex cable.
Edit: I disassembled the phone again and took a closer look on the flex cable: the lower part (with the LCD connection etc) looks quite same except for 3 or 4 transistors and their position on the PCB. The upper part with the earpice looks way different. The positioning of the single parts is not the same. But how can that interfere ? Guess there is no problem with the mainboard or the LCD (which is brand new).
Here are some pictures

OK, i solved the problem. The guy who sold the flex cable sent me a older one as I described. This thing was fully responsible for the errors. Bought a new one and everything works fine now^^ So if you ever want to change your Flex cable take good care which one you buy (especially on ebay!)
Btw: The display and the digitizer are glued and IF you want to replace any of those two, do yourself the favor and buy the complete bundle !!! I made the mistake and tried to replace the digitizer and cracked the display. There is no way as far as I can say, that you can manage this.
Bye
Can u post the seller info? Im in the same situation w a different phone... Thanks

problems with 1 year old ZenFone2 4gb

Hi everyone, I bought this ZenFone2 4gb 64g, recently it got soaked in my pocket due to rain and now has a few problems such as vibrating motor not working, microphone and speakers not working and screen timeout not working as well.
the problem is that due to job I relocated to Pakistan and here there is no one with replacement parts for this phone neither do they have experience of it. I have located parts on aliexpress.com but I am reluctant to open it up myself.
ASUS says Thayer its warranty was only 6 months so I am left with no options. Help me guys if you know something which can be done.
Thanks
Its easy to open. Need just the right tools. I think you may need to change docking port chip. Its about 6$ at aliexpress. Changed mine.. There are a lots of guides in web. Try one.
If you don't want to change it, just order it and go to some Asus repair center or any cellphone, smartphone repair center. And tell them you're problem firstly. Anyone with normal knowledge about a smartphone could do this.
Ofcourse if you do it yourself there can be problems, that i had : Broken antenna cable (I changed display- twice), broke the battery (i was a fool ).
Little Instruction: Take back cover off, take all the screws out, they are about 10, don't remeber really. Unplug SIM, SD flex cable, that is on the docking port chip.
Remove Antenna, very carefully. And replace it.

Lenovo P2 charging board change

To cut the long story short, firstly the fast charging stopped working, and now I can't connect my P2 (p2a42 exactly according to my phone) to my computer.
So I came to a conclusion that there's something wrong with the usb port/board. Ordered a new one from UK. BUT when I disassembled my device, I noticed some differences between the replacement and original part. On the original I have four rectangular contact surfaces on one side of the board, but in the replacement, there's only two, so I'm not sure if this is going to work
Well, I went on to ebay once again, and looked for a picture that shows exactly the same board as the original part. Bought it and when it arrived, its actually just like the one replacement part I got earlier
So maybe it'll work though it doesn't look like it would?
(sorry can't post pictures cause I'm new here)
