I have just been on the phone with an ASUS support Tech, and he has told me that one model of PSU has a known fault.
The model number is : 0B-LF.
Unfortunately my PSU is 0B-1LF, and as it does NOT have a known fault, it looks like I am going to be returning the whole tablet.
I had the option to return only the PSU, but if it turned out to be a tablet fault I would then be liable for any shipping costs for the second RMA.
As I have a few problems with case creek and speaker popping I will be returning the whole thing.
No Transformer for 7-10 days, and then all the hassle of reinstalling..
What a pain.
If you have the Charger with model number above,I Suggest you call ASUS asap.
You can get a cheaper call to the tech support by calling 01442202700 in the UK, and then requesting a transfer in the menus (saynoto0870.com ftw).

Mine is OB-1LF, how is that the same as OB-LF and whats faulty about it? My TF isn't faulty, would they just replace the power supply
0B-LF has a KNOWN to asus fault and will probably just be swapped out (i have no confirmation of this)
0B-1LF dosen't have a known fault, so if you have no problem then no need to get it replaced.

Mine says 0B-1LF too, I bought my TF-101 yesterday brand new. I would suggest the OB-1LF is the new revision.

Thanks, I read what you said wrong I thought you were listing your model as equal to the faulty model, thanks for the info.
+1 on the confusing OP.
it seems like what you're saying is,
1) your tf has problems
2) a certain model# is know to asus to having problem
3) unforutately, you have a diff model #
4) therefore you gotta send yours back.
statements 1 and 4 doesn't seem to have anything to do with 2 and 3. it's quite confusing.

Perfectly clear and set out logically in first post. Don't see why people are having a hard time understanding it tbh. I would imagine that there aren't that many 0B-LF chargers circulating around. Usually anything to do with power adapter faults on a large-ish scale and it's an automatic recall required. The writing is ridiculously small on it though. Doesnt help that it has multiple languages on it either.

Apologies, I agree it wasn't 100% clear!
I say it is unfortunate that my charger isn't on the known fault list, because that means they won't just send me a new one, Instead I have to send back my entire TF so they can do the same fault finding I have already done.
I mainly opened this thread so that the faulty model number could be made public.
Fault Description Post?
Hi, can you briefly describe or point me to the post that talks about the PSU issue relating to the the faulty model discussed above? Thanks in advance.

Afraid not, I got the information from an ASUS tech when on the phone about my own faulty PSU.
There are several other threads on faulty PSU's, but no one was listing model numbers until now
Type of fault
So I guess what happened to your PSU was pretty much does not charge the tablet (battery level keep draining rather than increase) even though everything plugged in correctly?
Did it work previously and just suddenly when dead on the charging? Or this is first try of charging and not working?
Also, do you have dock unit and trying the PSU on it too? Just try to see if it was the dang PSU or the plug connector or the tablet connector itself.

I disagree with your comment that the first post was perfectly clear and set out logically. It was very poorly punctuated, and if I read the first sentence literally, ending after the word tablet, I would conclude that he is returning the TF because of the OB-1LF. I was able to glean his actual meaning from his follow up posting.
bbilko would do future readers a favor if he could edit the original post, and clean it up, since that is the first thing they will read on the subject.
Agreed, if you read past the line breaks then you would come to the correct conclusion that I am returning the entire tablet.
I have however taken your point and amended the post to make things clearer.
I am afraid at the time I wrote it I was rather annoyed.

All right, it could have been clearer but it's not like it was cryptic.
He rang them >was told a certain model has a fault >he doesnt have that model >had to send whole lot back to be tested to make sure it wasnt anything else causing the problems, rather than just the charger on its own. =a logical progression.
Something that isnt logical is that I normally read threads backwards (newest posts first). Usually glean some handy info quicker that way. If everyone on these forums who started a post, added extra info from the rest of the thread (as time went on), to the original post, it would make things a lot easier to find/read up on, as you say for this post. But most the time it just doesnt happen unfortunately.
Anyways I'm still thankful he gave us some info, that no one else has reported on so far, in the first place.

My model number on my PSU is AD8-27M...does anyone else have something similar....or am I looking in the wrong place?

Hi,
I have a Galaxy S3 that does not switch on, or charge. Full disclosure; I bought it second hand in full cognisance of this fact*, but I really thought it was a software glitch or something I could fix with a hard reset. The reason for this is the guy I bought it from swears blind it's not water-damaged, which I've verified by checking the moisture sensors. So, I tried a hardware reset (volume up+power button+home button) but nothing. So, does anyone know what it could be other than water-damage**?
*Yes, I'm aware it was stupid. But it was really cheap, and I have very poor impulse control. I'm like a cat, you can't dangle something like that in front of me and not expect me to pounce on it ;p
**Screen appears to be in perfect condition.
Take the battery out and look at the model number....im worried your the victim of a chinese dud!

Nope, it's got Samung logos and all that; it says the SSN is I9300GSMH, which as far as I'm aware is the real deal. I've also checked the IMEI, and it corresponds to a real SGS3. So what is wrong with it?

As previously discussed in another thread, the chinese fakes look the real deal, all branding, samsung logos, model numbers etc match up to actual s3 devices, but the hardware is fake 540x960 display, 512mb ram etc....seriously worth looking into buddy
Sent from my GT-I9300 using xda premium
Impossible to tell unless it switches on though.
I've compared it to the (apparently) real S3 in this video, and while everything seems to match up with mine, one thing is the microSD card slot and SIM tray have weird blue windows in them, which looks a bit suspicious. Did anyone else's phone arrive with these? It looks like they're replacements.
I don't want to sound too depressing but some of us have had our phones completely die for no reason after a few months. Mine's currently at the service centre and others who have had theirs back say that the circuit board was replaced. Mine didn't get wet, or dropped, it just stopped working.
Sent from my GT-I9100 using xda premium
That *is* mildly depressing but if it comes to that I suppose all I can do is return it or sell it on as spares, try to get the money back :/ (all while hoping it *is* genuine)
(The circuit boards are really expensive to replace, also.)
Update: (like anyone's interested, but anyway) got my USB jig today, plugged it in following the method on this forum, but nothing. Not really surprised tbh.
Going to try a new battery next, but seriously doubt it'll come back to life at this stage. Thanks for the suggestions and comments anyway, and if any users have anything not covered already, just post it below. Thnx
Thought I'd update this again to report the lack of success of a battery switch....again, not really surprising.
I also need to reiterate the point that mine arrived with what looks like a replacement SIM tray/sdcard slot rig, such as those you see on eBay. I'm not sure whether to take this as suspicious or...what, and am now just ready to give up entirely on the phone. Any advice before I do this would be welcome
Do you mean those translucent blue stickers on the sim and micro sd slots? My phone came back from the service centre with these too (which definitely weren't there when I took it in)

Only thing you can do is go to a reparation serves center for a replacement.

I have bought a brand new unlock phone from a samsung store and have also the blue stickers.
It's normal.
Sometimes they are removed en sometimes thy leave them on.
Hi guys I was having issues connecting my new SII to my att network. I checked the imei using the *#06# and it came back with the generic samsung imei of 00499010640000. When I went to check behind the battery cover it also showed the same imei printed there.
This seems shady as I know that imei is the generic samsung imei when the efs folder gets corrupted. It is worrysome to see the same imei on the back of the phone as I think this means this phone is fake or a prototype.
I bought the phone on ebay from a chinese seller and I've already been refunded my money and told to keep the device by ebay since it doesn't work and they also believe it is fake.
What are your thoughts? The phone never connects to 3g but it will connect over gprs and load pages. However it won't make calls. Very strange. By the way I've flashed stock gb ics and jb and they all work with exception of the modem.
Thanks
Can ypu post more info on this device?
Remove battery, SD and SIM card and take a picture. Also screenshot about screen and the device's box.

It doesn't have to be a knock-off... But it could be some sort of a prototype or a development model. There is no way in hell this phone is from a regular production run - not with the IMEI sticker like this. And the hardware design differences are quite significant from a standard i9100. True, all manufacturers always leave their options open to change the specs or design without notice, but how many people have actually seen this variant IRL or even on the photos? "Fake" or not, this is definitely an oddball...
Could this be the chinese variant of the gt i 9100?

You could but you won't, it's not strictly legal.
You've been refunded so keep that device and do whatever you want with it, who knows, maybe you'll need some parts one day.
Now focus on getting an I9100, the real thing
You could also contact samsung and see what they have to say about a what-is-seems-to-be legit I9100 with a generic IMEI (Branded under the battery).

thanks for your reply. All the info that you have read are from service manual but I can't go ahead if not have confirm of part description. In service manual have only part number or I'm wrog?
thanks again
You have admitted that changing individual components is not easy (damage to two other parts while replacing one) the fact of the matter is that all the components on that board are micro sized and surface mounted....aka...really difficult to successfully replace....you could end up paying a small fortune to get that board working again.....
Why not just "cut your losses" and buy the entire board from somewhere like ebay for what amounts to small pocket change.
But be advised....there are 3 versions of this module available. ...rev 2.2, rev 2.3 and rev 2.4
You have to match the module in your phone or it STILL won't work...

It's very difficult find to a good price the low price that I've found is 100€. rev are for all country? I can change with a motherboard of other country without problem? if someone can help with a good price or with components I will be very happy. Thanks keithross39!
The "rev" version is dependent on how old the phone is.....it's not country specific as the voltage available at the charger output is USB standard. ....
Take a look at this thread. ....

it'll show you where to find the right version number.
When I replaced the board, I got my replacement from ebay for £6 gbp (7-8 €?) So it's really not that expensive to do......
Edit....it's the USB charger board, NOT the motherboard that you need to search ebay for.....

If it wasn't it wouldn't be there, if they could save money by not having to pay for the design, jumper and getting it soldered on across there millions of devices im sure it wouldn't be there.
