[Q] Unlocked ATT Bootloader - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I got my phone Wednesday May 22 and the first time I powered it on, I noticed a weird splash screen. It said "Samsung Custom" and had a picture of an unlocked padlock in between the words. So I'm guessing the bootloader is unlocked on my phone, has anyone else noticed this on their phone? I didn't notice this splash screen when I was at my AT&T store when the lady was setting up my phone in front of me. Is that the unlocked bootloader splash screen? It comes before the S4 boot screen. I feel like i unlocked it while applying the Developer Options trick. I'd love to hear other's experience

Obviously you have done quite a bit too your phone before powering it on. No you're not unlocked, you're just in custom status. You're rooted which you did or someone did before you got your phone.
Also this thread does not belong in this section, this is not the QA forum.

Please use the forums "search" function for the answer. This topic has been discussed several times and you need to do a lot of reading before you do anything to your phone. The several "root" threads that already exist would be a good place to start. It is good practice (and forum rules) to always search before you post. Good luck.

Searching would of gotten you the answer as others have stated but to answer your question. Is that you most likely got a refurbished S4 that was rooted before & they didn't bother to get rid of root when they returned it. I know you get that once you root it.

+1, got the same splash screen on phone on release day..no root, just stock. Returned that phone due to microsd errors. The second phone, shows the same splash screen. No root. All I've done is freeze the bloatware. I've had no problems with the phone, so I don't pay attention to it anymore.
edit: I did unlock the sim using the steps in the first post of this thread http://forum.xda-developers.com/showthread.php?t=2285431

9100 3G bricked, or something worse?

Hi, I'm a Newbie as You can see I will try to describe my problem. I have a qtek 9100, and I (being so dummy) flashed a wrong hard spl from another phone, (I don't know, from what phone, I just surfed google) and now the phone doesn't do anything, I tried to cold reset it but it didn't worked, I tried to push all the buttons and power it on, that didn't worked too can You suggest me something? its a 3G model, if You need more info, just ask, I will try to answer
could Anybody Help me?
Please
...heh....
Please provide more info about your phone. What's the exact model. If you look under the battery of your phone you can see the model.
I think that you mistaken something. There is not any 9100 3G model. At your phone is there a second camera?-
sorry I mixed up sthg.
it's a T-Mobile phone, it was CID-Unlocked, and i don't know exactly, but under the battery it's written that it's wiza200
Take a look at this guide & follow the steps one by one. I hope that this will work.
If this don't work & you are sure your device is CID unlocked you can try flashing T-mobile 2.26 (with a little search you will find it ).
T-mobile have saved my a-s a lot of times .-
sorry, but that didn't helped for me.
the phone is not responding to anything, it is like a brick
when i press the camera button and the on/off button, nothing happens, no boot loader screen at all

Are you sure your battery is not completely dead? Do you have the original 1.0A charger?
Yes, I'm sure about the Battery
I Don't have the original charger, but I test the Battery with another phone, and it works fine..
I flashed a Wrong SPL.. isn't that the problem? and I don't know how to bring it back
I don't have time to search it but you can search for ''jump start'' or ''kick start''. It is a way to start your Wizard with a similar problem as yours. Simply you connect a 9v or 12v (I don't remember) to your battery & then you put it in your phone & it starts.
As you can see I can't remember exactly what you must do. Search it. The exact instructions are in the forum .-
Sorry, That didn't worked for me too.
The phone is Dead..
and I need to Bring It Back to Life..
You still haven't provided enough specifics about what happened and is happening to your device. Do any lights come on? What specific rom did you flash it with? You are going to have to search through the past discussions. Don't lose heart - others have gone through a similar ordeal.
Well, at least you can still sell it for parts...
I'm sorry to hear about your mistake, but that's why there are so many warnings to read and read more before flashing.

So that's it?
It's a brick?
The light does shine, but just after many random pushes of on/off button, reset and camera button. sometimes ir shines for a long time, and sometimes for just a second.
and i don't remember which rom did I flashed..
it was a long time ago..

HTC Pure (Diamond 2) housing

Hi friends,
because my Polaris died I'm going to buy a HTC Pure. And for this I have a couple questions for you:
first:
HTC Pure locked AT&T with SIM and CID lock, unlocking using Olipro unlock,
Will I can use it with all the operators worldwide and flash a custum ROMs?
and second:
Can I change the body from

for such
Do it fit into the motherboard?
SIM and CID should set you up.
Regarding your housing, not sure about the fit, but you should consider the number of screen failures with the Topaz is high compared to the Pure which I have not seen.
Yes, if you are going to use Olipro, it will work, I did the same thing on my Pure and it works great now.
As for the second qn, don't do that, it will not fit.

What do you mean with "screen failures", this problem relates to the release of a series of defective devices?
Please tell me what I should first pay attention.
Diamond2 has wery sensitive touch screen and it mailfunctions if the device is carried in pockets/bags with screen unprotected
search the forum for "touch sreen woun't untouch" or somethnig like that....my first screen failed to untouch 3 months after purchase, secondone is 6 months after still working with no problem, but allready has a slightly visible dent in lover third of the screen....build quality sucks*, big time (and still woun't sell mine )
*first screen was replaced under warranty, and as I write my device is again at warranty service - volume buttons started pressing randomly....strange( currently I'm not selling mine, but I'am one stupid failure away from selling....phone is scratchless! )

If you search the forums for "Newton Rings" you will see many posts regarding Topaz screen failures. Some users had theirs fail 2 or 3 times after repairs.
I'm not sure if it was a specific bad batch released somewhere but I have not seen this issue on any Pure.
I can tell you that the Pure will fit in the Diamond 2 housing(and vise versa) but the problem is the antenna. If you could find an antenna for the TD2 housing, it would work, otherwise you would just have a PDA
oops..... repeated posts
TNX friends, the "oil" Newton ring, its something strange, and I disappointed in HTC Support. I will looked around the screen carefully and check for defects when my Topaz arrived, and in future will use screen protector. I read that overheating caused the newton ring.
If I find Diamond2 antena ill try to replace housing of Pure and will se what we got.
Again thanks for replying, how many did not seek, has not found information about the change of the houing, and known problems with Topaz, and here just only clear answers from You.

Lenovo K1 - *everything* force closes on startup

Hi guys,
One of my cousins has a Lenovo K1 tablet. Recently when we booted it up and as soon as we unlock the lockscreen on initial start up, EVERYTHING force closes. We get pop ups about various processes that force closed and all we can do is press "OK" and the pop ups just keep coming and coming.
My cousin isn't very tech savy. He doesn't even remember what he was installing or what he was doing when it started doing this. He doesn't even know which Android version it has. All we can assume is that it is running stock. The basic font and theme makes me think it is on ICS but we aren't sure. The pop ups are so irritating, we can't even go into settings or do a factory reset
Another bad thing is that my cousin has lost the data cable. All he has is the tab and the power adapter for charging.
Is there any future to this tab ? What can I do to help ? I am not even sure whether there is a recovery option in this K1 tablet or not and how to boot into recovery.
If I am successful in booting into recovery, I can hopefully flash one of the latest 4.2.2 JB roms here
Any help in this regards will be highly appreciated.
Thanx a lot in advance. Desperately waiting for a reply
Hi guys,
It's been a very long time since I got a reply, but nonetheless I'll try again and this time with pics.
I am going to order the data cable now either from the US Ebay site or DX.com site.
But in the mean time, now I have the tablet in my hands, and when I start it up, it shows this lockscreen...

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
In the lower right corner, you can see the battery icon and there it says "No internet connection".
After that, when I unlock it, it immediately shows VARIOUS Force Close popups, which look like this...
And when I try to LONG PRESS the power button, it simply shows this message "Power Off - Would you like to shutdown" and there is OK and Cancel. It looks like this...
From the looks of the lockscreen, it seems that it is stock ICS or something. I am not sure. I am unable to open or go anywhere When long pressing the power button, there is NO OPTION for "Boot into recovery" or anything. Is there any way I can factory reset this tab WITHOUT the data cable ? I have ordered the data cable, but it will take at least 10 to 15 days to reach me.
What would you guys suggest I do ?
Thanx a lot in advance for any help
Alright, so I did a lot of research and found out that my only option is to order a data cable and connect the tablet using that data cable to the PC in APX mode and reflash.
Thought I should mention it in case someone has problems like me and comes looking for answers

Once you have the data cable follow the instructions for flashing a rom with NVFlash, I would suggest KASCHEMME.S CM 10.1.

Network blocked z1 compact

I bought recently a z1 compact from ebay and from my unknowledge that guy told me that the phone is locked on o2, but not hardly locked. I accessed that service menu where you can find that your attempts to unlock it by code but is says that i have 0 attempts left. My question is.... Can i do something with this phone to get it unlocked somehow? I tried to go to o2 stores and to call at a sony service center but with no luck. They need the owner's agreement. Thank you!

Not sure which menu you're referring to but if it's the one I think a 0 means it's already unlocked.
I forgot to mention that at network i have that X, [x] to be more specific. If anybody has an idea what can i do with this phone, just let me know. Thank you!
It sounds like if there is an [x] on network, and a zero at the end, you have no more attempts left. But have you actually tried putting in a SIM from another carrier yet? See what it says. If the person who sold you the phone lied to you, then you should consider registering a complaint or asking to return it.
My Z1C was from Sony (no carrier) so it came unlocked. Mine looks like this:

I think X indicates that there is a lock. What network are you actually on @BogdanBagdasar? O2 contract users can unlock for FREE
It's locked on o2 and a tried everything.... flashed a new firmware getting the same problem.... i tried to unlock bootloader. Nothing works. I went to O2 store and they told me that without the customer who bought this phone we can do nothing. I called at sony service center, they told me that they need approval from O2, but i don't have that guy.. And i am not a O2 customer. I tried also to switch the sim cards. with no luck. It says that I need the unlocking code which i bought 3 weeks ago and i haven't new that the phone i blocked. the reason of opening this post is: Can I do something with this phone to get it unlocked somehow through USB or anyway? Despite of whatever things I done by now.

Have you asked the person you bought it off to unlock it using the O2 process? The only way to unlock is by code, there are no tools here to do that unfortunately.

Can't boot to download mode, twrp, sytem and so on

Hi Guys, I need help, I cant boot my device, the blue led always on and cannot turn off the device.
I tried to look over the forum but I found nothing similar to my case.
first. I always have random freeze and rebooting, none of custom roms helps, then I try several kernels, none of it worked. I booted in safe mode, still the same. and I flash stock several times but still the same.
and yesterday, it turned off, wont booted or turned on at all, even button wont work, when I connected to charger, it wont show led, I guess my battery is the problem. then I shake my phone gently, finally it booted.
and this morning, it suddenly turn of to boot screen, I cant event enter recovery or download mode. try force restart several times but then it show s7edge boot screen then show the black scrren and red writing. now I cannot turn it off.
I tried to connect to smart switch, it recognized my device but stated that my device is not supported for initializing.
I cannot even connect it to charger.
Anybody please help me, before I take it back to service centre.
thanks in advance

hi there, exactly, I never saw something like this before. I couldn't turn off. so I just leave it in cool room (16 degree celcius, air conditioned room) to prevent it over heating and explode ( lol I was scared lol)
and it just turn off, and I tried to enter download mode again, it worked, but lol when restarting it stuck and bootloop again (freeze at bootloop).
I guess I need to take it for service though, I am pretty much sure it has something to do with hardware
That's the Bootloader Exception BUG. Not really a bug, but defect. This error is shown when there are bad blocks on the flash nand chip. Some users had luck continuously trying to reboot to download mode. Others didn't. Either way it is a hardware defect. You better give it to service.
