Board fits with a little modification of the pcb corner but the connector from the usb/touch keypad is at a different place and doesnt fit.
you could get it to work but would have to also replace the touch button pcb and usb pcb from a L720 model along with the motherboard.

Hi guys,
i need a help before i buy something i will not use:
I have a dead herm100 (no gsm problem) and i can buy on ebay a HERM200 with broken LCD.
Is the HERM100 LCD and TouchScreen compatible with HERM200?
are the flex cables behind it the same as well?
thank you for your help

HTC used at least three different LCD screens made by different manufacturers. You need to get a match or they will not work. The digitizer circuits are differnt for each one (that's why you need a match).
The only way to know for sure is to look at the label on the back of the LCD.
I have written a post somewhere on each manufacturer, but basically it would be a gamble unless you see the labels. Perhaps if you have relatively close serial numbers you might be ok. There is some serial number info on the wiki.

thank you very much mike,
your words where very usefull for me...i probably will keep my herm100 dead, i don't want to risk money!
Hi All
I have acquired an old HD2 (India version 'unlocked') from a cousin. The phone's touch screen is not responding and I believe I would have to get it replaced (or do so myself).
Now to resurrect HD2 I need an LCD + touch screen digitiser (the screen is cracked at the bottom n I can even see bit of the chip inside). Hence the following questions:
1. Does anyone know if the Indian version has a socket type or solder type of LCD + digitizer panel?
2. Anywhere I can get an OEM version of the panel? (preferably in India or at the least delivered in India)
3. What will it cost me if I go to the service center to get it replaced if anyone has an expericene with service center in Delhi (I would be going to a service center in New Delhi)
There is a slight chance that I might need to get the buttons ribbon replaced as well. I would not be keen on spending too much.
Any input is appreciated. (Just in case this thread should be in another section or if the question has been asked before, I apologise in advance. The MODs can move it to the appropriate location.)

AFAIK there are only 3 types of HD2:
- EU/International
- TMOUS
- Telstra
I don't really know what the last one is, but you can tell the EU and TMOUS apart easily. If the phone has a T-Mobile branding at the top and has green and red call and end call buttons then it's TMOUS. Otherwise the likelihood is that it's an EU/International (no T-Mobile logo and white buttons). Figure out which yours is and then find a guide to take apart and replace the screen of that particular model.
Thanks!! It has white buttons n no T-mobile branding (T-mobile is not there in India). So I suppose it is the international version.
I believe the International variant has a solder type of connection. Am I correct?
Now only if some Indian folks can guide me where to find the parts (which can be shipped to India, don't want to end up spending too much) or some feedback on the service centers in India.
Edit: How much would it cost getting this done in UK? I'm gonna be in UK at this month's end.

As far as you need a combo(lcd+touchscreen), it doesn't matter what type, any model for hd2 can be mounted on.
Finding it on ebay could be the cheapest choice, most of suppliers deliver worldwide.
Be careful if buying from ebay as quality of parts vary drastically ...
full lcd & digitizers as a matching pair will cross fit to any HD2.
You can see the digitizer type in original bootloader screen details:
"MicroP (Touch) 0x30" you have inside your Phone a "60H00295" *solder
"MicroP (Touch) 0x50" you have inside your Phone a "60H00300" *connector
After my AT&T Samsung Galaxy S4 screen cracked I figured that buying a new screen on eBay was the best course of action to take to fix the phone. While browsing for the best screen I came across a cheap listing of a Samsung Galaxy S4 already assembled screen (apparently the unit was DOA but the screen worked). Naively I thought buying this listing would be most convienent: all I had to do was switch out the internals and I would have a working phone and screen without having to take out the hairdryer.
It turns out, however, that I mistakenly bought the SGH-I720 model. There are several differences between the I720 model and the I1337 model. The external loud speaker from AT&T, for example, does not fit the I720 model. The digitizer touch component (located to the left of the battery) is constructed differently. The back casing (the plastic mold covering the internals) will not fit on the I720 model because of this digitzer component. Oh, and apparently I do not get any GSM service from my AT&T carrier.
The rest of the phone works perfectly though. Wifi, bluetooth, the camera -- etc. Everything else that was transfered over with the main motherboard works.
I suspect it's an antenna issue. Obviously, right? I do get some service though! I just have limited GSM connectivity. Is this because of a carrier lock? The key difference between the I720 and the I1337 is the bottom part of the phones (underneath the loud speaker). It appears that the I720 model has two antennas whereas my I1337 phone only has one. I'm assuming the I720 is capable of GSM connectivity (it says so on the product page) and therefore believe that the GSM antenna (on the right of the battery) should work. I also believe that it is properly working. Why else would I have signal (albeit weaker than I'd typically expect -- but that could be because I haven't fully constructed the phone and the case isn't on etc, etc.
So my question is: does anyone know how the carrier lock works? Does Sprint have it hardwired in the phone or is it purely software? If it is a software thing than I shouldn't have an issue -- I do, after all, have an AT&T phone in a Sprint body. Does anyone here with better technical expertise know why the bottom half of an I720 phone is simply incompatible with a motherboard from I1337? For testing purposes I connected the antenna from the motherboard in the I720 to the bottom half of the broken I1337 phone. I still get service but again -- limited connectivity and emergency calls only.
Any help? I'm thinking I should just cut my losses and buy a new screen and just manually replace the screen on the I1337 but I'm sitting on a working front end to a I720 and I really really want to make this work.
EDIT: I realize that it's L720 and not I720. Oops.
But here's an update: I moved back the motherboard from the L720 to the I1337 (where it came from originally). I just plugged in the screen from the L720 so that I could see what was going on (the I1337 screen is flat out broken). TURNS OUT that I don't get service period from the I1337 model! Which hopefully means that a) I'm not connecting something right or b) it's a really simple software issue that you guys know how to fix?
I did try calling 911 and I did hear a voice on the other side very briefly. I immediately hung up. So I have a feeling that my phone is connected to a network but isn't being properly recognized. Is there an emergency number that I could call to test my phone (that's obviously not 911)? I just want to hear a reocrded message or something that gives me a set of instructions...
You cannot use the L720 for any network other than Sprint in the USA. You have to call Sprint to unlock it internationally and then enter a gsm sim while out of the country and only then can you use it. There are several threads that explain all of this already. Just a suggestion but don't call 911 and hang up.

Dude, I'm confused... You have an L720 logic board inside of an I337 body or is it the other way around?
Sorry for the confusion. I have the logicboard of an I1337 (AT&T) inside of the body of L720 (Sprint). The only Sprint components of the phone are the body, the LCD / digitizer, and the small electronic board found towards the bottom of the device (one end of the antenna is connected here . . . the other end on the logic board). See my attachment to get an idea of what I'm talking about when I say "bottom of the device."
Regarding using the L720 in the US with other networks: I understand that the L720 is locked to the Sprint network. However, I have an AT&T (I1337) logic board. Where does the lock come into play? If the lock is software based... it shouldn't be an issue. If the lock is hardware based but isolated on the logic board... it shouldn't be an issue.
same issue
Any luck resolving this issue?
Hi all,
I have uncommon issue after replacing digitizer in my phone. When I connected new digitizer, the device doesn't boot up, when I connect previous, crashed one, everything works fine. I found out that the chip on ribbon has different symbol but seller said it's "original one from grand prime duos and it's compatible with grand prime".
Chip on original digitizer - BT541C
Chip on "compatible" digitizer - Synaptics S5000B-5
First, obvious thing is there are not compatible and the replacement is just a fake...but how this guy could sell a lot of that digitizers and nobody could notice any issue with it?
Should I somehow "setup" my phone with new digitizer or buy a new one, with excactly the same chip?
Try downloading the kernel source code and building it with that chip module, however I don't think that might work so yeah...
Yeah if the module on the digitizer is different it's not going to work, your salesman is lying to protect the sale. You need a digitizer that's set up with the same module as the original digitizer buddy
Greetings fellow note enthusiasts. I have a N910T that I'm trying to replace the glass/ digitizer on and currently not successful. I bought a used unit off ebay that was previously on a N910F. The glass digital was still on the N910F frame so I just swapped everything from my own unit over in hopes it would work. In my mind the only difference between part compatability would lay in the modem chip set for the cellular band communication. However I'm not looking sure where those are located. Long story short, after assembly the phone doesn't boot up. It was functional last time it was put away and now it's not. Am I going to have to separate the glass/ digi from the N910F frame and over to mine? I thought the problem could lie in the secondary board at the bottom of the phone that has the micro USB and nav buttons.
