I asked the guys at service center and they told me there's no problem in the availability of spare components or motherboards for Galaxy R.
I don't know why this is happening with some of the guys on this forum.

They are being absolutely foolish and must have got through insane loss due to HORRIBLE stock India firmware and must have replaced motherboards of 100% of the units coming for repair as they can not officially install other country firmware and no other firmware is available for India!
Imagine the kind of losses they have gone through just because they had a buggy firmware! I don't understand why the dev team who developed such firmware wasn't fired immediately and a new firmware written or the other country firmware ported to India.
I can't do anything other than pulling my hair seeing such a silly situation when they stopped selling these phones and later offering refund when you go with a dead phone which again could well be due to the horrible firmware slowly eating the phone through continuous freeze/reboot cycles.
TERRIBLE!

So do you think this is because of INDIAN firmware, if we flash I9103ZSKK5 (2.3.6) which is non INDIAN firmware we can save our mobile from these kind of issues..

It has nothing to do with firmware , but probably the tegra .
Herpderp Defy.

The problem I think is not in Tegra otherwise many other handsets using Tegra would also face similar issues.
The problem could be due to a faulty batch of Galaxy R s manufactured from the Samsung plant itself. And that batch could have been unfortunately destined for India.
Not every handset in India has these problems, so I think only a faulty batch is the culprit, as not everyone is facing the issues.
If everyone in every handset had been facing these issues then the model would have been taken off the market.

i am also assuming the same i found in so many blogs mainly INDIAN handsets are only getting problems which are released in 2012..

Had you guys rooted your phones? Had customer ROM/Kernel's installed? Wonder if the either of these have made the phone die, or wonder if its the hardware batch?!! Hmm?!!! What was the date on the box?
Also, if you had rooted it and had custom ROM, Samsung guys agreed for the refund??

+1 cooleagle..
imo its got nothing to do with faulty rom or faulty processor.. just that that piece was a faulty h/w piece..
i never had a single reboot or freeze with my indian rom.. but i am currently at infected v1..

Yeah probably faulty hardware. Its good that they are getting the full refund. But, when in such a situation and you have installed different ROM/Firmware/kernel and your phone does not even boot up. You don't have option to even restore back. So, was asking guys whether they had rooted the phones and still they are getting the refund as Sammy guys also had no way to check it up?!!

I want to know if the Galaxy R is root,
and the phone hardware is broken,
Samsung service center will repair the phone in the warranty?

My phone freezes every other day, Touchscreen does not respond, My screen weirds up and selects **** on its own, I cant hear a person on the other side sometimes when I call...I have to reboot it to get it solved.

I suggest stick with the phone for a month or so.Even I face problems with my phone occasionally.The ICS update is expected within a month which I feel will solve the bugs which have been affecting our phone.If you are still not satisfied after the update then you can think of asking for a replacement/refund

That was quick! But then, correct me if I am wrong the warranty is for 6 months?
And I am not sure if we are going to be updated it with ICS in 2 months.

As far as I understand the warranty on the battery and accessories is for 6 months,the handset itself is secure for 1 year.So no worries there.And the ICS update is expected within the next 1.5 months.
The point is if the bugs are to such an extent that they are really hampering your everyday usage then you should get it replaced soon. In my case I need to restart my phone probably once a day and it really doesnt affect me that much

I hope they come up with a update soon enough. They don't even have the courtesy to come up with a 2.3.6 update to fix these bugs.
It is quite annoying when i have to reboot my phone. It takes a while to reboot.
Anyways, Thanks and Cheers bud!

No such problem faced by me.
My touchscreen was giving some issues and stopped responding altogether in a particular region, so i went in to the service center and my Galaxy R was repaired in about 30 mins. The whole LCD unit was changed.
And no such problems (reboots, hanging of phone) have been faced by me! I am on stock Indian firmware 2.3.5 (Latest here) and i have only rooted it, no custom kernel for me.

Nexus 5 bricked after switching off

Hi all!
I switched off my phone to charge the battery and after switch it back on, it started to shut down an freeze. Then things went worse and it couldn't even start to the home screen so I decided to restore it to it defaults.
When I tried to flash the files Google provide in their page it says something like "write failure" after trying to write bootloader and boot files. I've tried with the OEM cable and in different PC's with same result.
My next try was to flash it with the LG tool which failed at the beginning because of a blank model. I got the build.prop file form another Nexus 5 and then I could start flashing, but it always fails at 80% saying something like bad response...
Any thoughts?

Emmc (flash chip) gone bad. Buy new motherboard or claim your warranty or RMA your device.

Hi bitdomo, thanks for your response!
I think my warranty is avoided since the terminal was rooted :_(
Any suggestion about where to buy the motherboard? Is it difficult to replace?
Thanks!

if you have bought the device from Google Play Store, then you can RMA it since Google doesn't care whether it's rooted or not. If it's LG you're dealing with, then you might be in trouble.
Replacing the motherboard is fairly easy and there are tons of tutorials showing the same. However, if you're going to pay for it, might as well get it done from LG since you get a warranty on the same!

I bought it from Google Play Store in Spain, and after contacting them they tried to send me to LG because it's rooted...
I'll give it a try with Google Ireland because it's where I'm currently living.

Well, not trying to be negative but warranty is only valid in the country you bought in.
Let's hope for the best!

Lg cant find out your phone is rooted because your phone does not boot up. Also LG use a service called RCT (root checking tool), which is installed on every LG phone and can be accessed in hidden menu, to determine your phone is rooted or not, but this app service is not present on nexus 5 since lg just gave the hardware and google the software. The other way how LG check root is that they boot the phone into download moda and if the phone is rooted it will show a red rooted text on the screen, otherwise it showes a white not rooted text. This feature also missing from nexus 5's download mode.
As I read you bought it from google. Since you bought it from them your warranty only valid in that country where you bought it. You have to go back to that country, send it back to google that your phone stopped working, and that is all. If you cant go back to that country then you have to take it to LG they will replace the faulty motherboard if you pay them to do that or you can order d821 motherboard from uk for almost the price of a new nexus 5 http://www.mobiledeviceworkshop.co....ard-main-board-replacement-service-2167-p.asp

Galaxy reboots itself

Hi All
Received my SH-G920I (unlocked) and for the last 2 days I faced three occasional reboots.
Once it was when phone was idle, then when I try to unlock it and once it was in the middle of web browsing.
It looks like "fast" reboot, when only "Samsung" logo displayed briefly and phone is quickly coming back to working mode. Sometimes after such reboot screen and soft buttons aren't responding and I have to turn it off/on with power button. Them it back to normal
Any ides what is it?
Thank you.

My G920i (got it from eBay) is doing the same thing...hope it's not a hardware issue...

Yes, my from eBay as well. For last 24 hours it worked without reboots. Not sure how promising this might be....

Bought a G920I from ebay myself, arrived yesterday. So far noticed :
- 2 soft reboots (really dim Samsung boot animation, then fine)
- CONSTANTLY reboots on mains charger all night (annoying as it was lighting up in middle of night)
- Reboots on wireless charger constantly (standard Qi cheap one - not sure about officiall)
I have not rooted my phone, it's completely stock.
Is this just the G920I or are other people having problems? I am thinking of returning it for the G920F model.

Better to replace it.

Who was your seller one Bay? Maybe it is the problem of specific shop/batch.

I have the same problem with a SH-G920F

My god! I started a new thread about this without finding this first. I bought my 920i from the same seller and am facing the same problem! So any idea if this is a batch issue or general issue that quite a few are facing? I have asked for a refund and hope that I am not charged a restocking fee , which in this case is 20% which is too much.

I sent request to Samsung support so they advise if this is hardware issue and we should replace the device or software one that can be mitigated.

Please keep us posted ! I think this could be a software issue

On top of the random "soft boot" my S6 has has an issue with the SIM tray not sitting completely flush with the frame. The top portion (the section where you can insert the ejection pin) tends to stick out a little bit (about 0.1 or 0.2mm). I have had quite a few phones with similar designs (iPhone 6+, M8, M9) and this is the first time I run into this kind of issue. I am starting to think this particular batch has a bad QC or something. I message the eBay seller yesterday asking for a return/refund but have not hear back from them yet. A little bit frustrating to say the least.

So you are facing soft boot issues and sim card tray issues? That sucks. I heard back from the seller and he asked me if I wanted an exchange or refund. I have asked for a refund and am expecting RMA any time today. Seller has also increased the price to 839 now.

Yea, it definitely sucked. How did you contact the seller on eBay, did you just asked him a general question or you used the specific "return" link? I think I can going to request a refund too as this point. I was trying to be nice by avoiding the use of the "requesting a refund" link as I think it count against the seller but they are not replying to the question I initiated yesterday at all.
Thanks,

Since it is the weekend so they may take some time to reply but so far they have been co operative. I am definitely getting a refund and I hope they don't apply the restocking 20% fee. It breaks my heart because I really liked this phone.
Back to the Oneplus for now.

Samsung support replied, that they are unable to provide any information since I have non US model. They sugested to seek resolution with the support in country where device was purchased or directly with retailer.
So, guys, are you all returning it?

Honestly I really like the phone alot and would've most likely kept it if not for the raised SIM Tray. The random soft boot really didn't bother me as much as the physical SIM tray issue.... I liked how this int'l version can change the APN settings for you depends on what SIM card you are using (I tried both T-Mo and AT&T) which I know the AT&T version will not even I get it unlocked. But then the AT&T model is built in Korea verses the int'l version which is built in Vietnam. Not sure if is correlated but T-Mobile's version is also built in Vietnam and there seems to be quite a bit of issues with that batch too.

I am still confused about what I am going to do. I like everything else about the phone and I think this reboot issue should be fixed via a software update , but the question is , are there enough of us facing this issue for samsung to do something about it?

I like it as well, but a minute ago it will not turn on untill I pressed on power button and then he made soft reset again. It doesn't look good.

HI, It is happening to me too. I have same phone. Had it for about a week and last 2 days it rebooted itself 3 times. Any news about it?

Is there anything that can be done with a bricked Flex 2?

I was tired and very short on time and got careless. I tried to unroot my Flex 2 by using the LG flash tool but because I didnt read enough, I did it wrong and now my phone wont turn on, wont charge, and cant get into download mode.
Should I put it in a drawer and wait until someone figures out how to unbrick or sell on ebay as broken? Kind of depressed right now...

How much did it cost? Or did they do it under warranty?

They repair it under warranty.
Usually phones have 1 yr factory warranty, so bountyman has sent it twice if im not mistaken.
If you're in the US send it in for repair.

I've just sent mine off for repair.
I bricked it editing system files, tried to use the flash tool but it didn't work so just took it straight to the store and they sent it off no questions asked.
The only problem now (aside from not having my phone) is that this time of year it can take up to 2 weeks to get it back.
If you are worried about them refusing because you voided the warranty, just tell them that you installed an official update and it wouldnt work after that. They can't argue if you make it look like it's their fault.
I'll admit it's wrong to lie but, it's an expensive phone.

thanks for the replies. I've started the repair process via email, had to ask them if I could still do it without proof of purchase and they said they will look up IMEI to verify manufactured date (it was 04/2015). Email support must be somewhere across the globe from me because I got a very fast response at 1am CT but no response during business hours.
I've learned my lesson. No rooting or unrooting as long as I have little kids that wear me out and leave me with no time to research.

LG G4 stuck in bootloop - RMA only solution

My AT&T LG G4 got stuck in bootloop today 810, ser. number 505, H/W 1.0, on 10o, no root, all stock. Apparently this is a hardware problem that has been affecting more and more G4 owners:
http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734
Called up AT&T, and they're sending another G4, which is the only way to fix this. Warranty will continue through the end of the original G4.
UPDATE: Received the replacement G4 from AT&T. Unfortunately another 505 serial number, H/W 1.0, with 10o.

Yea that happened to me too... I bought it at launch weekend. Replaced under warranty
Sent from my LG-H810 using Tapatalk

Yep just happened to mine the other day. was look at a forum web site and the phone locked up then boot looped. called the att warranty center and they sent me a "like new" one. positive not about the new one it was manufactured 12/23/2015 according to https://imeidata.net/warranty/lg

Add another AT&T variant to the failure list. Mine froze and went into irrecoverable bootloop Saturday night. It's on the FedEx truck now to the LG Ft Worth Repair center. The more research I've done, the more I'm seeing it's a common hardware issue. I'll be posting mine for sale the second I get my replacement or "repaired" phone back. I'm back to using my first gen Moto X and I forgot how smooth it ran. I think I'll be getting the X Pure Edition to replace the G4.

is there a way to factory reset the phone. my phone just died this morning and i just spoke to ATT they will be sending a replacement. not sure if my phone rooted will void anything

Another AT&T fail. Mine died a week ago. Serial 505. Lasted 8 months. Replacement is also a serial 505.

SN 806
Ive seen some posts and I have had this happen to day halfway to a meeting and lost my gps and contacts. I have an 806 serial and anything to save it would be great. I dont know how to get to dload mode or I might try something more.

My friend's G4 AT&T fails to. She asks me to help her but there is no way to make it work. Really confused. The problem is she buy the AT&T version, and then buy the unlock code to make it the international one. Now she stays in Vietnam, not US, how can we get the warranty ?

that isn't good. so this just happens randomly? I'm on 10o all stock with 505.

Same here. Happened the morning of January 28 (1/28). Started bootlooping. It would sometimes get past the AT&T logo, but most of the time bootlooped at the LG logo. AT&T did an overnight replacement which was a much newer hardware version. So I'm suspect based on the HW version this was a new phone not a refurbished. Still 5.1 (no marshmellow). It has been flawless. Even taking my 128GB microSD which failed to work on the previous hardware - which would spontaneously software eject.
AT&T said it was probably related to the Android 6.0 marshmallow update. The store rep said that I was the 6th person to come into the store with the same issue. The tried factory reset themselves with no avail. Then had a phone overnighted to my home.
Sure sounds like a hardware issue with the H810.

Hey guys,
I have a confirmed fix that i applied to a friends phone.
It involved opening the phone up and applying pressure to one of the chips.
Will post video/more info for those who are interested.

Some of the other G4 boards here on XDA show G4's that have been disassembled, and the motherboard is baked in the oven for several minutes. This apparently melts and the resin or adhesive that holds the chip that is causing problems. After heating up, the chip apparently re-seats itself, at least temporarily, allowing the phone to boot up. Apparently it's easy to get the G4 apart, but that probably would affect your warranty. At least you could get valuable info off the phone if that was absolutely necessary.

Same here guys . LG G4 BOOTLOOP STUCK .. . Now I have a cheap phone ( Alcatel idol 3 ) wich works better than lg .and super fast unfortunately front can not good as lg ...bit is OK my lg is now at garbage RIP. LG G4

Mine's a 508... However it still affected me, when I called LG they said it's probably an update, however it never completed it. TurnOn > Freeze > BootLoop. Looking at the PR Distributor cause well.
Can you believe Claro PR (my carrier) didn't accept it cause it has a bruise on the top right edge (metal side, not even the screen), when I asked LG for repairs (phone call) they said they won't take it either (the first time I called), the 2nd time I called they said they wouldn't take it cause the LG-H810PR is apparently an International version, and so I needed to look up with My Carrier (Claro, yay...) ultimately, I read this >> http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/ << And it led me to PR's LG Distributor and hopefully they'll do a repair or give me a replacement. If they don't, well you'll see me doing a topic.

My AT&T LG G4 got stuck in bootloop today 810, ser. number 505, H/W 1.0, on 10o, no root, all stock. Apparently this is a hardware problem that has been affecting more and more G4 owners:

Called up AT&T, and they're sending another G4, which is the only way to fix this. Warranty will continue through the end of the original G4.
UPDATE: Received the replacement G4 from AT&T. Unfortunately another 505 serial number, H/W 1.0, with 10o.

Where is the serial located ? I have my box.. tried to call local AT&T & they said they considered the IMEI to be the serial..
Would like to confirm if the one I got is a 505 or not..

Mines a 509 just shut off in the middle of chromecasting from plex, and just loops at the LG logo. I got it as a replacement in December for my G3 that randomly died. I going to fight ATT to send me something other than another G4.
