[Question] What makes the bootloader so different? - AT&T Samsung Galaxy S 5

Why is the bootloader in 5.1.1 so different than the other bootloaders in other Samsung devices and/ or phones? Is it loaded with top notch security protocols that are just unhackable? I see other s5 being modified as such but is this phone that locked up?

Here's a somewhat simplified breakdown. Our bootloader is set to only recognize official Samsung signed updates and kernels. We can't get change the bootloader because we need root to do that. We can't get a different kernel because we have a locked bootloader. It is a loop of security measures that was bypassed on some of the other phones by replacing the bootloader with one that will recognize other builds and was meant for developers to test out features and stability of new builds. We are not lucky enough to have such a bootloader accessible.

Is there any chance that anyone will bypass the bootloader lock for the ATT G870A any time soon? Anyone working on it?

It doesn't look too good for it being unlocked soon. I'm personally hoping for a vulnerability like the keyboard when lollipop came out to be shipped with marshmallow which we have yet to receive. General consensus, though, is that we are pretty much a lost cause at this point if you have the newer updates.

Im a g4 user been a while since ive ad a samsung. But if its anything like lg they use 256 bit encryption on all boot partitions. Now when it comes to 256 bit encryption it could take the fastest computers plural 10 years plus to brute force the passkey. So actually just cracking the encrytion is usually pointless to try. Only kinda hope is in exploits. Which ive seen come years later on a device. For instance my kindle fire 3rd gen hd 2012 release twrp and root 6 months ago. I feel development is over unles u have a officially unlockable device any more. Or by cheap arse lowend garbage which is now starting with encrytions too. Basicly kitkat and earlier devices. I know in marshmallow the bootloader also does integrity checks on system partitions so even if theryre modified with locked bl. Secure boot error.

For your answer. New bootloader basicly is encypted. Maybe qfuses also features antirollback. So make a lot harder to downgrade which is usually only possible with jtags or octo boxes
Most of kk bl unlocks. Were exploits and not actuall unlocks. Just bypasses which most were hunted found and patched. But again new exploits are found everday. As computer skilz advance and software new hole open all the time

Yes i'm VERY Happy to see I will be seeing Jelly Bean before the end of the year. I think AFTER that is when i'll think about rooting the phone so I can get rid of all the damn AT&T bloatware on there.
I am pretty computer savvy and i've built several of my own computers over the years but the thought of rooting the phone kind of intimidates me because I know almost NOTHING about the process and I still as yet have to see a clear thread that says "This is how you do it, This is how you undo it" in case something goes wrong with the phone that's not software related and it needs to be returned or whatnot.
Also there are alot of threads about custom rom versions but they say you need to have the "base" 4.1.1 version first which again i'm a bit lost at trying to sift thru all the forum posts to find. Heh.
P.S. Annnnnndddd...i'm a retard. Somehow right after I made this post when it went back to the post list page for this forum now right there in my face is a post titled "Jellybean rom leak - step by step guide for updating" LMAO.
I do have a more pertinent question of someone with some know how here though also. I saw that Moto has started selling the developer version of this phone which i'm assuming has an unlocked bootloader as from what I understand that is kind of the point of the developer version. So I am curious, once someone has this developer phone will that make it easier for someone to develop something that is easier/faster/more stable to root for us poor schmucks who can't afford the 400+ duckets this phone is costing and also since we already have the phone to begin with?

Yea which is kind of sad considering. I mean it seems to me the only really bad thing about this phone i've found from using it is the lack of much user ROM and the stupid low Mah battery they put in it when the one from the Maxx will fit almost equally as well, and would have fit perfectly if the phone had been developed around it. <sigh>
It seems from the # of forum posts that the Galaxy S III is pretty much "THE" phone to have. I have a friend who just got one a month after I got my Atrix and she likes it well enough, but I can't understand what idiot at samsung decided it was a good idea to leave out USB Mass Storage on the thing, although i've heard that's getting officialy fixed, or may have been already since I don't really follow that phone.
The phone I upgraded from was an old Samsung with a physical slide out keyboard before the android days and the thing was junk to me, about all it was good for was texting because my fat fingers worked well with the physical keys. But almost all the apps on it were useless junk and alot never even ran. So i'm kind of burned out on Samsung right now.
I've been in computers for years and have learned to trust Motorola for reliability and stability and while their products have not always been hugely inspired or innovative, they have always been reliable to me.
I had thought I saw one of the people who seemed to be doing development for this phone in a message say they already had a developer phone on order or whatnot. But maybe it was just my wishful thinking. In any case I hope this phone dosnt die some slow horrible death in here just because it's not as bright and shiny and full of awesomeness as some other phones out now. Once the Jellybean update officially comes out for the phone hopefully there will still be good people in here who can easily make the phone rootable and that will pretty much be good for me for the 2 years till AT&T says I can get the next shiny new toy out then. LOL. Custom roms are nice but i'm mostly interested in being able to get rid of all the AT&T crapware in the phone because it's pretty much just useless spacewaste to me.
Itll come out December 31st

The SIM in your phone won't affect you getting updates.
I was disappointed when I saw Bell wouldn't get it until Q1 '13. I have a Bell Atrix HD, but I use it on T-mobile. Could someone explain to me why an AT&T ROM would brick the phone? I don't get it.
What do you guys think it will be? 4.2 or 4.2.1?

We ran into this problem over at the A2 forum. Hardware is all the same, so to speak. But the firmware is slightly different. I guess it would be like comparing windows XP vs windows 7?......or maybe that's a bad example.

If you have a locked bootloader each partition is signature checked for your device and region/carrier. Bell files will brick ATT phones and vice versa thanks to locked bootloaders.

Are you sure you will be able to retain root with the update? What method did you use to root in the first place by the way?

I really can't speak to the OTA, but I've read that those who installed the JB leak had success with Voodoo Root Keeper. It worked for me when the RAZR got ICS finally... I am just assuming that it will work when we get the OTA.

I saw on your other thread where you tested the various methods to root the Atrix HD that you mentioned rooting might take you off the OTA path. Do you mean to say that if I use motofail2go to root the phone, there is a chance that I may not be able to get the OTA update to JB when it rolls out?
Thanks.

[4.4.2] When?

Well... we are really grateful for this new Motorola been so attentive with us in order to provide the Kit Kat as fast as a Nexus device. But...
... as I'm reading about 4.4.1 and 4.4.2, these updates are major bug hunters, and not only a camera fix as "Google" says.
So, are Motorola working to implement this minor for us? Does anyone have an idea about it or can ask to Moto Care if there is any attempt from Moto about it?
The help desk from Moto here in Brazil is one step behind from US one cause we are partially receiving 4.4 by these days, so if 4.4 is something new to then to handle, imagine 4.4.2.
I made some research on news but unsuccessful.
This is likely why most other companies don't rush to release a new version of Android. They will go through all the effort of packaging, testing and releasing only to be screwed by Google a week later with a new update. I doubt the carriers like it either, as they like to test stuff.
Once something has been out for a bit and the major bugs are dealt with then it would be much easier to release. This is a bit of a flaw in how Google's android model works.
It would be much more ideal for Motorola to have adopted the Apple model where they release a new build and don't really care much what the carrier thinks.
I am sure someone at Motorola is already working with 4.4.2 but considering the number of carriers that don't have 4.4 yet it is hard to say what they will do. Maybe they will hold off on them and switch to a 4.4.2 build for the ones who haven't received 4.4 yet.
To keep up with the new android releases, the bloatware some carriers insist upon, builds for the different hardware models and then a huge number of different carriers must be quite the fun project to manage.
I heard that the 4.4.1 and 4.4.2 updates only had fixes for the nexuses devices and wont be pushed to any other kit kat devices
Kit kat blows. That's my scientific analysis. Doesn't matter what device section you go to.... You will read about a lot of bugs. They "almost" squashed flash. It locks some brands boot loaders... From what I recall. They are trying to stop root. They are trying to stop 3rd party battery analysis apps.... Etc... Etc. Basically they seem to be trying to squash development.... Oh... Unless you buy a special developer model of a brand. Lol
Anyway.... My point is... 4.4 is awful. Let's hope they do a better job with 5.0. And they stop leaning toward the apple philosophy of not letting people "play" with their phones.
Every device section I follow has threads about kit kat... And when will they get it. Then when they do, theirs tonnes of negative threads about it.
4.2.2.....the last best version. At this point.

Not really... 4.4.1 was a big update regarding KitKat performance and bugfixes...
You can check the commits to see that they've changed A LOT of stuff in Android framework...
We definitely MUST have the 4.4.2 update... 4.4 is a bit laggy... 4.2.2 was much more stable...

Buy a Developer edition so you have a unlocked boot loader. If you buy retail expect it to be locked down and lucky if a exploit is found.

I have the Rogers version... I'm all unlocked.
I was talking about devices in general. Google and the carriers are making it tough on people to unlock... Root... Etc.... On many devices.
I have zero problems with my Moto X. I was knocking 4.4 and the direction Android in general seems to be heading.
Sent from my Moto X cell phone telephone...
There is a reason that Google, manufacturers and carriers are making devices more and more secure. There is demand for it. People don't want insecure devices that someone can randomly access. Or, the want a secure phone that is good for both personal and business use. While you say it's bad, it isn't. I'm not sure why you think a secure device is a bad thing, or why you expect the initial software release to be bug free. I don't think there has been an Android release yet that hasn't seen a few quick incremental updates just after initial release to fix bugs.
Also, 4.4.1 and 4.4.2 are more than just "Nexus updates". Sure, the updates mainly apply to Nexus phones because they're the only ones running 4.4.0 really, other than the Moto X. There is a lot of stuff fixed that will apply to all devices running the software, not just Nexus phones.
The HTC One GPE 4.4.2 rollout is in progress, so it's definitely coming to non-Nexus phones.

To add to that, Google also has an obligation to fix root exploits (and they are exploits on locked devices; Nexus devices will always be developer devices at heart) now that they offer TV Shows and Movies in the Play Store. Some app developers (game developers usually) also had to implement nasty DRM because of pirating, which sucks because a lot of games have to "check-in" to verify the license; so, if you don't have internet at the time of check-in, you don't get to play. The more Google can control on MAINSTREAM devices, the better for their long term contracts with studios (music, movies, television) and publishers (magazines, books).
I used to NEED root, but the Moto X actually changed my mind about that.

No, it wouldn't have because no other mobile OEM in the world has the kind of sway with carriers that Apple has. Apple blew open the mobile industry. Don't forget that. As much as I love android, those are the facts. Sure, I'd love for that to change sooner rather than later. You can see small battles over this happening all the time. N7 2013 has the chips for VZW LTE bands. VZW suddenly decided not to activate N7s on their network. A customer would essentially have to nag and harass VZW to get it activated. Or, you could take an already activated LTE VZW sim and just pop it in.
There are many battles being waged that you may not be aware of. It's unlikely someone will win the war soon. But join the battle by voting with your wallet.

This is simply not true. Following the history of previous Android release, the .0 release always came with a lot of small bugs. Otherwise, there won't be any subsequent point releases. For example, 4.2 was released on 11/13/2012, just 14 days later, there was a 4.2.1 release.

I never said it was realistic, but I would prefer it if it were possible. My carrier doesn't even sell the Moto X, I had to buy one from another carrier and unlock it. No developer edition or motomaker in Canada either.

Nice! I'm working on it: I suspended my VZW accounts, trying out tmo prepaid. I can't lie though, I'm very interested in seeing the effects of the bandwidth improvements vz made in my area. Another local xda user posted a speedtest screen that was 3x the performance of vz at it's peak. Maybe I'll borrow a sim from a friend...

That's exactly what I did. Wanted to replace my s2...and buy a phone outright and say goodbye to contacts. I'm on telus. Did a tonne of reading, reviews and articles and XDA of course. Was between the G2, HTC one and the moto x. Decided on the X. And couldn't be happier.
For the Rogers version, unlocked sim, then boot loader... And rooted. The phone blows me away.

Everything about your "scientific analysis" is wrong. Go back to the drawing board.

Is rooting G900A officially dead?

My original GS5 had a broken gyroscope and I had it replaced a few weeks ago. I didn't expect or realize that Asurian, the company that does At&t's insurance, would send me one running Lollipop, still in original packaging no less. After trying and failing to downgrade to 4.4.2 for hours, I found out that it's not possible.
So, with no exploits to work with, a locked and encrypted bootloader, and some Xposed Modules no longer working from the looks of some forum posts, is GS5 rooting officially dead? Is there some other option that hasn't been considered to acquire root? Since I'm out of warranty, I don't care about tripping KNOX.
Is it possible to completely remove all the software on the phone and replace it with rooted software? I know it may sound idiotic, but I'm no developer, just a guy who likes tinkering with tech, so go easy on me please. I only ask this because I was thinking of getting some outside help to possibly decrypt the bootloader. I've read on other forums that trying to decrypt a phone bootloader is a worthless endeavour but it didn't stop me from looking. As it turns out, even with an extensive Google search, there is no explaination of the subject of bootloader decryption, no software to use, no experts in the field explaining their experience or anything at all helpful.
I'm very much pissed that my first dive into the Android (customizable) experience with the GS5 was first stilted by At&t and now killed. I have not seen any updates indicating any progress on rooting and I'm hoping it's only because I missed it. Considering the time elapsed and the bounty for decrypting the software never being claimed, shall I lose hope and wait out this crappy device until I can buy a new one? Or, is root still of some concern?
Hey, I'm sorry to hear about your loss of root. As far as I know it's dead for now unless someone comes up with something. Not sure if anyone has tried flashing a boot loader from another carrier or not but, that might work. Only thing is, if it doesn't you lost your phone.

Yeah, that will brick the phone. Can't flash bootloaders from other carriers to a locked bootloader.

Guess we may need to raise another $18,000 for developing a root. Is there no other geobot out there talented enough?

If I could find a SM-G800M at a decent price, I would! It's the only mini model with all four of the same LTE and LTE-A bands that AT&T operates.

Furious over the forced 5.0 FOTA upgrade with ATT's bootloader and no way to flash 4.4.2. or a custom rom...

I'll donate large sums to this cause just on principle.
ATT hasn't completely locked down their Galaxy Notes (it can be flashed back to their 4.4.2 stock rom from 5.0.1)... Just primarily their S5...
Maybe a dev can look into this for a possible root...

There is a part of the article that mentions root access is possible, now if it could be a permanent root is the real question.

I posed the same question, whether the devs thought stagefright could be used to facilitate rooting the ATT Note 4 and @graydiggy was awesome at explaining the exploit may only work on phones without write protection (the Nexus line).
Wonder if Joshua Drake (who discovered the flaw) would be willing to assist xdaers with this ATT S5 root issue should a proper bounty be offered. Seems Google paid him only about $1500 for reporting the problem and for the patches he created and sent (to Google)...
Currently, @Kingxteam gets mad respect for developing a tool to root otherwise unrootable phones. They have yet to add ATT's galaxy S5 (SM-900A) to their list of supported phones but I suspect they're working on it. Maybe PM them?
Hope is good thing... maybe the best of things.

Go Kingxteam !!! All glory and honor and praise to you all -- especially if you can "tame this wild horse" with a root. :victory:
I'm new to all this rooting and don't understand any of the language yet but would like to start rooting. Unfortunately the phone I have seems to be unrootable. Anyone know if I can root my memo pad 7 on AT&T don't know model number but I do know it's running kk4.4
Just got this phone a week ago and returning/exchanging isn't an option for me. I really hope there are still some ambitious devs out there looking for a solution to rooting the lollipop OC4 version, although I fear the majority have moved on. :crying:

WARNING: PingPong Root Users Do NOT Update to 5.1.1

I have gotten a few private messages plus some people have posted on the threads with the updates.
Do NOT update to 5.1.1 if you want to maintain root.
After days of tinkering, here are your possible outcomes (none of which are what you want):
A. Continuous soft reboot after upgrading via FlashFire updates.
B. Use ODIN to flash the system/boot partitions or properly done FlashFire update... Hoorah! You're on 5.1.1, but your fingerprint sensor and LTE are dead - plus no root.
C. You try to downgrade after B, and you no longer have signal under any circumstance.
Personally, I am now just going to flash the OI2 ODIN files in full and be done with it until a new root method is available. Sorry guys, I have tried everything that I can think of. As you can see above that something in the 5.1.1 kernel/system images require the latest bootloader which is what allows us to downgrade and get root from OE2 using PingPong.
There is a possibility of a new solution soon enough... see progress here for other models of S6: UniKernel
Yeah I ended up tripping knox in my attempts at working something out. Fortunately I was able to revert but thats only because I didn't dare try and flash the bootloader or modem. Man this is like a sick mind-game. I wish I would have had more experience with Samsung and AT&T before I bought this damn phone. This is my first phone on AT&T and my first Samsung. It was the perfect **** storm... I never anticipated this bull****, after this long... And I can't even get rid of the damn thing. Nobody wants it.

Forgive my ignorance here...I've not kept close track of the progress of unikernel. But it was my impression that without a custom recovery option, we are entirely SOL regarding custom kernels. Am I misunderstanding things, or did something change? I didn't see anything in the recent posts there that got my hopes up...

Well technically you can flash the kernel using FlashFire however a screen will stop you from booting.. Says something about at&t detecting modified software on your device please take to repair center blah blah

Gah! I don't even use custom roms. Stupid Textra App has this ****ty ghost notification that does not work on 5.0.x android. I would go to 5.1 unrooted but I just can't stand the thought of not being able to get rid of annoying notifications (wifi, etc). Plus all the custom easy hacks. So lame. Never going AT&T again. Why do they make it so difficult anyways? Tmobile doesn't.
They make the majority of their money from enterprise customers. These customers desire the locked bootloader as to avoid security risks. Since this is AT&T's main source of profit this is their main consideration. In short this phone and its software was not designed with our consumer use cases in mind. We are merely an after thought. I have waited too long I am jumping ship, just ordered a Moto X Pure and as soon as it gets here I am leaving this phone behind. Had it since launch and haven't been able to accomplish my original intention since then. Never buying from AT&T and also I am staying far away from anything with an Exynos chipset. Touch Wiz is a lag fest nightmare. For this to be pretty much the most powerful chip in the mobile space and to experience such a lag on it is truly unnerving. Samsung is all too eager to jump the Android band wagon all together and probably intend to do so as soon as they feel their tizen offerings stack up. And I sincerely hope they fail miserably. They are a good hardware company but they should just give up on software. They just don't get it at all.

Amen. Well said. Bravo.... I feel your pain. My first real SmartPhone was the Fire Phone with AT&T, exactly a year ago, and I took its enema for 10+ months before I finally decided to just add payments for the S6 and finally have a good phone I could root. So now I'm paying for both, and the more I search for help and answers on here, the more I feel like my kind aren't welcome. Not by the community, but by ATT and Samsung. Gee thanks.
Well, at least I have a new phone... I'm totally down to build and burn a 5.1.1 effigy with you, if you want.
Well I have already given up on this phone. See my post above. My sister has already agreed to take over the line and the phone payment and I just bought a Moto X Pure outright yesterday. Just waiting for it to arrive now.
I've been thinking of just doing an Odin back to stock (unrooted) and OTA update up to the newest 5.1.1 on my 925a for a week or so now. For anyone that is already on OI2, how is it working out for you? Is the phone still slow at times? Does the memory issues still exist?
I recall seeing an app a little while ago that is able to freeze/disable apps without root. What was that app? Has anyone tried doing something like this? How did it work out?

Appears this is where we come to an end with development and rooting. All other g4s have been Rooted on Android m. We just don't have any love for this device. Appears we all messed up when we chose sprint as our carrier. Argh!
Wat, who are you? What makes you think you can make that call? There are people that spent countless hours making ROMs and Developing for the Sprint LG G4 and you think you have the final say?
Quoting what you said just in case you edit you post: "Appears this is where we come to an end with development and rooting. All other g4s have been Rooted on Android m. We just don't have any love for this device. Appears we all messed up when we chose sprint as our carrier. Argh!" with screenshot: http://i.imgur.com/DxsEmvG.png
Not the right way to think, just wait. Have you contributed in anyway to the Sprint LG G4 here on XDA? I sure have with my free hotspot bug (patched on Android M).
I highly doubt Verizon G4 is rooted on m.
In fact I don't think they even have Marshmallow update yet.
what is so appealing in Marshmallow to make one want to upgrade urgently? If you have stable L with root and xposed, why not staying with it. I do not think there is Xposed for M anyways yet, which is the main reason to root this phone.
I am with you. This phone is the most disappointing tech purchase in all my years of existence. I love the camera and removable battery but this phone is just crap and doesn't get much dev love. I beat if the bootloader got unlocked and I can load a true rom on it this phone would be great. I think most of the problems is LG's crappy modifications to android. Every time it get slow, unresponsive, the touch screen lags behind, or a stupid Sprint notification advertisement pops up I want to chuck it against a wall and then jump off a cliff.
I am just using this as a rude awakening to the future. This will most likely be one of the last phones that isn't sealed tight. Guess I need to carry around a clunky battery pack with cable dangling from my pockets instead of a small quick batter swap. Rooting and unlocking the bootloader will become ever more difficult with upcoming phones. The glory days are over I feel

I disabled and uninstalled everything I could with sprint software. Haven't had any of their pop ups in months. It seems you bought a phone in one of the bad batches with your lagging screen.
I hate their UI though...

Yep I had a bad batch phone and it was before Sprint admitted the problem so I sent it to LG. LG fixed my phone but did not replace it. That is probably the big problem. Now I have a phone that is only having lagging problems and since that is subjective and random so not easily repeatable I am screwed.

We do have Marshmallow, but the OTA is taking reaaaaaaaaaaaaaaaaaaaaaaaaally long.
I just got the notification a few minutes ago for the update. I'm from Michigan and figured I was one of the last places to get it but I guess not. Newho, I've read that there's gonna be more dev work on our g4 but they were waiting for Android m to come out before they focused their energy to cracking the bootloader. Stay patient as the carriers are getting wise to what our devs have been doing and they try to seal up the phone to keep us out. But when there's a will there's a way and it will happen eventually.
Well I'm hoping for ultrapop marshmallow, lol. The phone stock was fine and ultrapop was perfect for me. Would be nice to have cm in this phone but ultrapop was all I really need.

Don't think that's gonna happen, as MM security is the reason we don't even have systemless root yet. UltraPop relies on changing the system partition, which the Lollipop boot sequence isn't as strong. in MM as soon as the system partition is changed, it causes hashes and whatnot to change, the boot sequence detects the changes and doesn't allow the phone to boot. I think we'll need an unlocked bootloader for UP-type "pseudo-roms"

Exactly. I was able to work-around the system partition in ZV6 because LG security only checked for certain files were present. In ZV8, there is LG security checksum for the whole system partition. Since we have a locked bootloader, we can't modify Kernel without tripping the boot security. I am still going to try to get a modified stock ROM working, or maybe mix of ZV6/ZV8, but have not had much time lately.
Roms for our phone? please tell me where roms are at for our phone. i only see 1. that is still stock. ultrapop
Go to the Sprint Fun and Games app and hit the menu button, then settings, then deselect the box Atuomatically install Zone / Fun & Game updates and the notifications boxes. Super disappointed in Sprint for having this.

This phone has plenty of "dev love". Some of the best developers are trying their hand at it. There's a huge bounty for unlocking the bootloader, and plenty of people trying to earn it.
The problem is, until one of them (or the part timers like me) stumble across something that works, we're in a holding pattern. We have something stable that works in Android L with root and xposed framework, and until the bootloader issue is solved, that will have to do.
Be patient, OR hit the general Android development section and LEARN. Do it yourself. Grab the bounty. There's plenty of us doing what we can, even as far as hard bricking our devices and getting them replaced by trying methods that work for other devices. I myself am on my second LS991 from trying a method that worked on the kindle fire where you get into fastboot by nuking laf and still haven't had any luck getting a patched bootloader to stick.
So cool off and have some patience. Some people haven't even had the official OTA roll out to their area yet and you're crying that you don't have rooted M? Grow up.

Hello,
Thank you for your interest in LG mobile devices.
Currently, you can only unlock bootloader for LG G4 for the European market with model number H815.
And we have no plan to support bootloader unlocking for H815T.
If there are any changes to the supported devices, we will let you know via our website.
Thank you.

And? That doesn't mean they can't be unlocked by other means. It just means LG will not be providing the binary file for oem-unlock via fastboot. Some of us have already gotten limited fastboot access by willingly destroying the laf partition and using a serial USB connection. Right now I'm working on trying to figure out how to get access to other fastboot commands not available in this limited mode, then it's just a matter of creating a reliable semi-automated process so it's accessible to less technical users, and if no one beats me to it; collecting the bounty on a reliable bootloader unlock and ability to flash recovery and make it stick. (Which, to be absolutely honest ... Though I'm not working with anyone else, I would not have gotten *anywhere* without ideas others have bounced around on these forums that helped me make progress when stuck, so I will contact each of them privately to divide half of the bounty between them if I am first to be able to collect it)
