Bootloader - AT&T Samsung Galaxy S7 Edge Questions & Answers

Then snapdragon S7e have a locked bootloader, is it possible to swap the CPU with an exynos one so we can flash the custom stuff?

Sure. Find someone who has an Exynos (non-US) Galaxy S7 Edge and is willing to trade. Hand them your phone in exchange for theirs. Done!
Otherwise, no.

Means the exynos chipset won't work on my phone, because my friend broke his screen and willing to give his phone ?

These phones aren't meant to be opened period, never mind swapping chips on them. The displays are so integrated into the top-glass that swapping one is essentially swapping half the phone. I haven't seen the motherboard for an Exynos based S7 Edge, but I would imagine the batteries and displays are similar or identical, so you might get lucky and swap the bottom half to fix a broken screen. However, anything other than a gross repair (such as a display or charging port) either isn't doable, or isn't worth the effort. Even then, you have to get through the glass without breaking it. iFixit has a tutorial, but it involves a fair amount of skill and special tools.
If your friend has an otherwise working Exynos S7 Edge with a broken display, and you have a Snapdragon S7 Edge with a working display, you might be able to merge the two into a single working device, but I would suggest finding a skilled technician to do the work.

[Q] Broken Galaxy s5 LCD

hello guys. i do really need help.
im sorry i have some issue to be dealt with regarding to my hendheld which is samsung galaxy s5, i have a broken lcd with it and my samsung galaxy s5 is an korean version (SM-G900K). when i wanted to repair or replace it, i brought it to the samsung service center, however i lived in different country with the phone version, i live in indonesia. so just say that they (SSC) turned down my plea to repair my handheld because the version isn't available in the country and they're mumbling about not availability, different system and so on.
that was just a brief. actual question is, is the lcd version of all galaxy s5 versions are different each area? or all just the same and it's a kind of plug and play system whatsoever, so any version of lcds are aplicated one to another version. because if it possible i would just buy the sparepart of the s5's lcd and applicated by myself or private service center.
i asked dis question because this forum was one of helpful source of phone problem solver.
thank you very much i need a help really, hopefully you guys will.

You're unlikely to get a knowledgeable answer to this. It's too new of a model and few people will have experience yet with repairing models from multiple regions. So unless someone working in a very large service center or Samsung design happens to see this and post a reply..
All I can do is suggest that the situation is likely similar to previous models. For instance on the S3, all of the LCDs per se were identical amongst variants. However the electronics were physically different. The end result being that Exynos models were not compatible with Qualcomm handsets. Amongst Qualcomm variants, they electronics were electrically interchangeable but some e.g. Sprint had different physical layouts and would not physically fit into a different variant case unless they were modified.
There is a general push to standardize parts to make them interchangeable. But I suspect that Samsung's policy to deter black market sales and the large manufacturing runs would lead them to deliberately make some if not all models incompatible. The bottom line though is that we don't know or at least I don't know and am extrapolating from previous models.
You should try to find out if the part numbers are the same between variants. And perhaps call some of the largest part suppliers and see if they have any feedback about part interoperability.
.
Your best chance is if you or someone here maybe downloads the service manual for your model and compare to known models.
thank you very much it has been really helpful so far, im so desperate because i really need it, i hope more answers will be available for me. i'll try to do search more, and if there are more info's that u guys will have please be kind to inform me. thank you very much :good::good::good:

yes it is, i asked the previous question because, the availbility of the version that marketed in my country is sm-g900h, and mine is g900k. if i buy the lcd in my country im afraid the lcd that will be given to me by the ssc for only g900h or exynos type.
i saw the link before didn't mention about g900h, so it is possible that it was made for qualcomm type.
btw have you bought anything from brando shop?

No but they ship all around the world and the site seems reputable. If you pay with a credit card your purchase/money payed is insured also if something should go wrong.
I can only assume that you did a Google search for LCD parts before posting here (shame on you, if you didn't).
Anyway, the interesting observation of such a search is that various vendors have markedly different interoperbility claims. Some claim that their LCD will fit all U.S. S5 models. Others claim "most carriers", Qualcomm only or various subsets of Exynos and Qualcomm models. If the LCD is the same for all S5 models then that only highlights that the information for some vendors is egregiously wrong. So which vendors to trust?
There is no credible information about this yet. It's equally plausible that the LCD-digitizer assembly could be identical on all variants. Or that Samsung might have made a handful of different versions as they did for past Galaxy Sx models. Caveat emptor.

Hong Kong based online vendor. Not a Hong Kong BBB member. Generally positive reviews.
However, their refund policy explicitly states:
We can only give refund if you receive defective product/s from Brando Workshop and we can only replace defective product/s that are purchased from Brando Workshop and we will not be liable for purchase of wrong product.

Combine that with reports that they aren't always careful with their product specs and draw your own conclusions.
e.g. here:
"Dear friends,
I bought one pair of transceivers on Brando website (they are actually at the 2nd place on NGShopping "Most Popular")
link of the product:
http://www.ngshopping.com/Product-339408-Super-Power-10km-VHF-UHF-Dualband.aspx
UNFORTUNATELY the transceivers I received are NOT dual-band (VHF-UHF) as described on the site, but the Frequency Range is only: UHF: 400-470MHz.
They do not works on VHF!
I am disappointed, very very disappointed. I bought them mainly to use them on VHF because all my friends communicates on VHF frequencies.

Or look for another website where you can buy a S5 screen, Brando was just an example and you should always look into a site and search for user xperiences ordering from that site. But that is YOUR job, after all its your problem and we are just trying to assist

I realize it's been about a year and a half since this has been discussed, but I'm looking at about the same issue with my Verizon S5. The digitizer is fine but the lcd has apparently shot craps. The screens really are tough like advertised. I rolled over mine with a creeper while under a trailer and didn't so much as scratch the screen. The LCD on the other hand apparently got smashed due to the pressure. So. This is a US Verizon S5. I've looked at replacement LCD/digitizer combos which run at the cheapest I've seen about $127 USD. I only paid like $224 for the phone so not to hip about spending that much to fix it. I've found broken S5s on ebay(I think through US cellular and another company I'd have to look up the name of) for around $65. They have busted digitizers, but have working LCDs. That would work for me if 1. The LCD will work with my phone even though the carrier is different. I assume the model is the same? And 2. I can get the busted digitizer off of the good LCD without trearing up the good LCD, clean the adhesive off, get my working digitizer off my broken LCD without tearing up my digitizer, clean off adhesive and apply new adhesive to bond the two... UV adhesive I assume so that will mean more $$ yay hah Any thoughts on this?
Sorry @RunDickRun......I wouldn't even bother to attempt to remove the lcd from the digitizer.....The lcd is wafer thin and *incredibly* fragile......
You *will* break it if you attempt to separate it....it's pretty much guaranteed....

Yup. I've never had much luck with it before(I also didn't care about breaking the LCD before either). I've scratched that idea. Found a LCD/Digitizer for $90. That'll have to do I guess
Good luck fella.....going to be a hell of a lot easier than recycling parts of the old one.......
Where did you source the new one.....can you post a link in case others might need this?

Ebay. I've bought multiple screens and parts off Ebay. They are usually fair quality. Read the descriptions thoroughly is my only advice. Make sure you know exactly what you are getting and that you get exactly what you want.

Samsung USA Will Not Repair Cracked Screen if International Variant (G935F)

I have an international G935F phone that I use on Straight Talk (AT&T). I took it to the Samsung USA service center to get the screen replaced and they said they don't touch international phones because of different internals/parts. I also called the 800 number and they told me the same thing. Is this accurate? I know US and international use different processors (Exynos and Snapdragon) but I would think screen replacement would be pretty much the same with the same parts.
Policy is policy I guess.

Yep. Take it to a 3rd party repair shop and expect to pay $350 to have it fixed. Samsung won't touch it. Already went through this. Not fun.

I have purchased 2 S7 Edge International versions from Amazon - fulfilled by amazon, but 3rd party sellers, one a Dual Sim, and one single SIM. The product listing was somewhat vague, just listing International Warranty, may not be covered in the USA. So, I contacted the seller through Amazon support, and the response was, The warranty is International, HOWEVER, you'l have to send back the phone to Samsung the phone originally came from!!!. I ran Samsung info to find one is a Middle Eastern version with a model code ending in EG (Egypt), and the other is all in Chinese, even the default language in case of a hard reset is chinese (or Korean, or or or).
I've sort of accepted that there is no warranty, and hope no product fault happens while I have the phone. Here is the email from the seller:

Thanks for the reply - so, both the single and dual SIM S7 Edge in gold listed on the Technomaster Amazon store, will be covered by Samsung's international warranty outside of the USA- even though your Amazon listing states No Warranty?
Thanks.

Yeah we take the risk by buying these. I wouldn't even bother trying to deal with the logistics of sending these back to their origin for service. A local 3rd party repair shop will gladly take your money. Just make sure you choose one known for high quality work. My screen looks like new again after having been replaced. But again, very expensive exercise.

When I broke my S6 Edge screen, I sent it in for repair. When it came back, I found that in the process they had broken the speakerphone function, so I sent it back again, and this time was sent a new/refurbished device.
My point is that Samsung USA might not want to get involved with an international device, because they are aren't really set up to replace it if something goes wrong.
Just a thought, nothing more!

Dave

Don't know about the S7, but I recall that for one of my prior phones (The S3, maybe) there were enough differences in the internal layout that while the screen was functionally identical, the ribbon connector mounting location was different, and the parts weren't interchangeable for that reason.

To be honest, whatever the internals may be, all the versions are made, guaranteed, and endorsed by samsung - they should honour "international" warranty to the very common and basic definition of the word. Even Blackberry has set-up dedicated phone and warrnaty lines for the Priv. I have had a iphone bought in the UK off a craigslist equivalent website replaced without question at an apple store in NYC. The problem was real, I wasn't the original buyer, the "genius" wasn't bothered, was very apologetic that they didn't have the UK version in-store, but that they would have it in 2 days - left with a new phone for a 8 months old 2nd hand used phone. I'm no apple fan at all, but their customer support is beyond excellent. I know this is all factored in the price apple charges, but the S7 is no cheapie either.
Bottom line, it is pretty poor of Samsung to offer such a restrictive warranty.
Regards.

That is not the case with this phone.
This is an older post but I still wanted to respond to it. Today I experienced the same issue. The front and back screens are broken and my S7 edge is stuck in boot loop mode but after I pitched a fit over here with Samsung USA, they agreed to purge and force the IMEI number to be accepted by their system. They are to contact me in 24 - 72 hours once the IMEI number has been registered. I threatened with returning all of their phones to them and posting negative feedback on their facebook page. Within minutes they offered the above solution.
i have a s7 edge dual sim g935fd the sim lot may need to be replaced. my question is can i replace it whith a dual sim slot reader from a us version or not ?

V20 Motherboard Swap

Ok. Here's the situation. I own 2 V20s (buy one get one at launch).
One was never used. The other is my primary daily driver phone. Well... I dropped it and the screen is dead, but the motherboard is in perfect condition and still works.
Here's my question, can I simply just take my daily driver motherboard and swap it into my secondary V20 that was never used? Basically put my everyday motherboard into the phone casing from the never used V20? Will there be any complications (ESN, camera, force closes, etc)?
And if that's not possible, can a direct nand backup be flashed over without complication?
I ask this because I have done numerous hours of custom development for my own personal use that I REFUSE to loose.
Thank you so much to whomever can answer and help me.
EDIT
The casing on the daily phone was also slightly damaged, hence why I'm trying to do a full swap and not just the LCD.
PREMATURE BUMP
From the teardown videos I've watched, it appears that the radio/modem and motherboard are all one piece. So that will eliminate the ESN issues. Anything else that I should worry about?
I'm confused by the numerous hours of development statement in the same post as can I swap identical mother boards or do a NAND backup from one device to a identical device. Not trying or meaning to be rude just think about your post.....
The serial number will be the only difference regardless.
Personal choice. NAND backup then restore to the other device, unless you are 100% sure there is nothing wrong with the current motherboard, in which hot swap.
I'm assuming they are identical since it was BOGO as you stated. Don't know any place that would offer that and say give you a H918 V20 with a LS 997 V20.
I did same thing. I cracked my main screen on T-Mobile variant. I bought a bootlooped V10 on eBay that was Verizon. All parts in good condition, just a dead phone. Took them both apart and placed the tmobile motherboard into the verzon model. All went easy as pie. Only negative is that the one I picked up has lousy image retention. But otherwise perfect condition screen cosmetically.
Sent from my LG-H918 using Tapatalk
I think you will be fine but i recommend swapping over as many parts as possible to the new V20 or just take the screen off the new V20 and swap it with the cracked one. That's the safest option imo.
Thanks guys. Much appreciated. I know some phones don't like MoBo swaps unless you swap almost all the other parts also (S4 anyone?).
@DarkestSpawn Only reason I suggested the MoBo is because I was not sure if a NAND backup between phones would actually work correctly, considering different serial numbers. Never had attempted that before. Also, I do not have access to a PC right now. So the NAND backup would take some time. Trying for no downtime, hence the MoBo idea.

Believe it or not, my local verizon wireless had an amazing offer going on. They paid all termination fees and gave two free phones if you had good credit and switch service that day (one day flash sale), so I swapped service and got a Pixel XL instead. Unlimited photo storage ftw. :highfive:

S7 edge demo to full phone?

Can I swap motherboard from real s7 edge to demo unit, will phone calls etc... work?
I don't know, but I am going to attempt it.
Hi all,
I am going to attempt to replace the motherboard in a Galaxy S7 G930X (demo model without cellular radios), with a motherboard from a G930P (sprint model) that has a broken screen and LCD, but boots and has a clean IMEI number.
I have searched this forum to see if anyone else has done a cross-swap like this, but have found no answers except one failed attempt back in January 2017, and the guy was going to try again with a different motherboard -- but didn't update the thread to let us know how it worked out.
I'd really like to hear from others if they have had any issues doing motherboard swaps between carriers on the S7s. I understand that the hardware is about the same between the S7 and the S7 Edge, but I am not brave enough to attempt that swap.... Besides, I think there is special software to do special "edge" things that probably would mess things up in a plain S7....
Thanks in advance,
Philip
P.S. I will update this and the January 2017 thread with my results once I get the phones in hand and the replacement glass battery cover that I ordered from China. So be patient -- it may take a while for it all to get here....

Well, my first attempt didn't work out the way I had hoped.
Rather than post the results on multiple threads, here's a link to a new thread I started that documents the whole saga: starting with the reason I attempted this, the research done, the models purchased, the actual results from the attempt that documents what is different between the LDUs and their fully functional counterparts and the difficulties encountered, the alternative swap that was performed successfully, and some parting thoughts.
Here's the title and link to the post:
"Swap a good donor motherboard into a G930X LDU (Live Display Unit)? VERY HARD."

Replacing broken phone with a t-mobile s7 edge

Hello, I'm new to XDA and had a newb question:
I own an AT&T galaxy S7 Edge that I dropped and the screen shattered and the digitizer went to hell. I contacted Samsung and they quoted me around $300 to fix it without any assurances.... which is oh so kind. I was looking at craigslist and found a really cheap galaxy S7 edge from T-Mobile that has a bad IMEI on it. I know T-mobile has a weird unlocking app now and was wondering if I could flash Lineage OS or another OS onto my phone and then change the IMEI to my old phone to make it work?
No flashing of custom roms except for what's in the rom section of this thread which isn't what you are looking for. We have a locked boot loader and there is no twrp recovery meaning no aosp flashing of any kind, sorry.
you better get insurance or a really good case. the edge breaks easily and costs more to repair than to replace. I also prefer the non-edge phone because I keep having accidental touches.
