[Completed] [Q] Galaxy S3 - Not booting into CWM after install - XDA Assist

Hey guys, I'm having a pretty annoying issue with my Galaxy S3 (Verizon variant), and even though I'm pretty sure I know what the problem is, and that I screwed myself, I wanna know if there's another answer to what's going on.
As the title of this thing says, I tried installing Clockworkmod Recovery on my GS3, but I did it via the ROM Manager app, since I'd totally forgotten how to do it on my computer, and Odin 3.09 wouldn't use the .tar or .img files I tried using to install the damn thing (still haven't figured that out).
Anyway, I flashed the CWM file on the phone, installed it, and whenever I try booting into recovery, it says some unauthorized software is on the phone, and I need to take it to a Verizon store.
I'm pretty sure Verizon locked us out of our bootloader, and we need to unlock it before we can make mods like this, but, being that I haven't had a GS3 for two years, I didn't know that, and didn't look it up, like a n00b.
So, I think I just partially bricked my phone. So, yeah. That sucks.
Is there any way around this? Is there a way to revert back to the stock recovery mode, so I can try doing this whole thing again?
Some phone info:
It's the Verizon, I535 variant
Running 4.4.2, Kitkat
Build number: KOT49H.I535VRUDNE1
Any help would be appreciated.

recovery mode not accessible-N00B

i am extremely new to the rom/flashing/rooting scene. i recently used a "back door" rooting process, which worked great and i did all the recomended actions and apps: supersu titanium backup, root browser, etc. then i wanted to change my boot animation->samsung device-> flash a zip file to allow bootanimation.zip->samsung requires signature verification from stock recovery mode->cwm recovery(which flashes itself to the phone... curious why a custom recovery...or any recovery for that matter is even required if it isnt necessary...) -> recovery menu no longer accesible. i cant flash anything to my phone i tried changing the recovery to twrp but no dice. its giving me this dialog along with caution sign:"system software not authorized by verizon wireless has been found on your phone...etc" the phone is a samsung galaxy legend on verizon prepaid plan it is the jasper version of the samsung galaxy stellar. now for the question... What do i do so that i can flash files to my device?
i dont know much about unlocking the bootloader except that doing so with the wrong program will brick your phone and since im doing this recreationally on my primary phone i dont want to buy a new one. how can i regain access to my recovery menu/ unlock my bootloader?
its not a popular phone so i doubt anyone is going to be able to offer a one touch application to unlock the bootloader but any information would be helpful.if youre still reading this i thank you for any advice and i apologize if i : posted in the wrong section, offended anyone, or came off as a cheap experience-less n00b
EDIT: my phone is running 4.1.2 jellybean, baseband:i200ppvramh1, kernel: 3.0.31, build: jzo54k.i200ppvramh1, dont know if that will help any and before anyone criticizes me remember i am completely new to this forum posting thing but i guarentee i have scrounged this site the world over trying to get help but there just seems to be noone working on this problem the same as me...

[Completed] How do I unbrick my phone?

First of all, I'd like to say that I know very little about how Android, electronics or mobile phones work in general, so everything I've done has been from internet tutorials. Please don't use any jargon as I probably won't know what you mean. ELI5.
A few days ago, I tried to root my phone and it didn't work. As a result the phone went into a boot loop and I didn't know how to fix it. The long and short of it was that I ended up flashing the stock firmware onto my phone and basically doing a complete factory reset. After some time trying this I managed to get the phone to start up and I was able to access the interface and all that. Unfortunately, my WiFi wasn't working (the button would simply turn off whenever I turned it on) so I had no way to download the most recent updates or apps or anything like that. After following several tutorials on how to fix this, such as flashing the modems and bootloader, I still wasn't having any luck. So I tried something that proved to cause even more problems - I tried to install a new kernel. Now my phone won't even boot past the logo. I probably didn't install the right one, but what can I say, it's not very clear which one I need.
Now I'd like to point out that as a layman who just wants his phone to work again, half of the time I don't understand what I'm doing or whether or not I'm doing it right. In other words, I realise that I've probably messed up my phone, but what can I do? I can't take it to a technician because I don't have the money for that, I can't buy a new phone for the same reason and I can't phone up and ask for a replacement because the warranty expired ages ago and I don't have the original documents here.
I've installed the Team Win Recovery Project on my phone and I have Odin installed on my PC as well.
TLDR; yes, I know I'm an idiot and I don't appreciate you telling me. I'd like to reset my phone to how it was before - the normal firmware, the normal kernel and all that, but I'd still like to have root access and keep the TWRP recovery mode too.
Model: Samsung Galaxy S4 GT-I9505
Model name: GALAXY S4 LTE
Country: UK
Version: Android 5.0.1
You'll probably need more information, so if you do just let me know and, if possible, where I can find it.
I have some good news. I managed to flash the firmware again and now I can access the phone again. However, the WiFi problem persists. I've tried looking on the internet for a solution, but I can't find one. I've tried flashing the modem and all that stuff, but it still doesn't work.
Oh, and by the way, I no longer have TWRP and I don't think I have root access anymore either (I had to do a data partition wipe as well).
I'd really appreciate a reply from someone. I've tried everything, but to no avail.

Hi engloa,
It's OK, I've fixed the problem now; I installed a different ROM and now it works fine. Thanks anyway though.

Purchased a galaxy s3 for straight talk with cyanogenmod on it.

I bought a galaxy s3 for straighttalk from some one cuz it was really cheap. I want to remove cyanogenmod from it because the camera doesn't work and I can't save pictures. They didn't back up though so when I factory reset it, it brings it right back to cyanogenmod. How do I get the original OS for the s3 back on it? Im new to this kind of stuff so I didn't even know where to look on the forums here. And the person I bought it from is no help, I think they didn't even know how they really did it. Can some one help me or point me in the right direction please?
Sincerely,
Unmarked civillian

I need to know if you have the Sprint version (S960L) or the Verizon version (S968C). Most likely you have the S968C.
When you tell me your device model number, I can link you to your firmware and you can flash that via Odin.

If you want to flash the stock firmware, you will need to go to Sammobile.com and enter your model number in the search feature there. It will lead you to your firmware, download it on PC.
Make sure you have installed "USB drivers for Samsung phones", you can find them with a Google search, or if you already have Kies installed then you've got the drivers.
On the device, go to system settings>developer options(if you don't see this in settings, you need to go to the "About Phone" option, scroll down to the "Build Number" and tap it at least 7 times to enable Developer Options). In developer options, turn on "USB debugging".
Charge your battery to at least 75%.
Once charged, press and hold the volume down+home+power buttons, at the caution screen, press up to enter download mode.
Open Odin(make sure Kies is closed and isn't running in the background, it interferes with Odin), connect the device to PC with device in download mode. If the device is recognized, you'll get a colored COMM# box. If you don't have that, try a different USB port, make sure your cable is the stock cable.
In Odin, select the AP or PDA button(older Odin has PDA button, newer Odin has AP button). Go to where you downloaded and stored the firmware on your PC, select it.
When you get back to the Odin screen, make sure the only options that are checked are auto reboot and F. reset time.
Click start, when it is done, you will get a green PASS! and the device will reboot, go through setup wizard and enjoy your device.
you are the true MVP of the internet tonight! thanks so much for breaking it down for me haha ive asked all over, here and reddit and few other sites, no one would help me like that! the download for the firmware is going to be an hour from sammobile since im not paying for membership haha but i have work in the morning so ill let it run while i sleep, and do everything in the morning. ill post here tomorrow either in the morning or at night after work and let you know how it went! once again thanks again!

Did you make sure that the options I mentioned were set and ONLY those options when you flashed?
Try booting to stock recovery and do a factory reset and wipe cache partition in recovery then reboot.
i had auto reboot and f reset time and PDA checked. booting it in stock recovery, factory reset, and wipe cache partition worked! thanks so much for all your help! i have one more question for ya though. the reason i wanted to delete cyanogenmod is because the camera wouldnt load and i couldnt save images and i wasnt able to go online using data, i could only use wifi. so when out all i could do was call and text, and the mms didnt work. any clue as to why?

The ROMs were actually built for the Verizon S3(SCH-I535), they are 4G devices, this makes them require a SIM card to regulate the 4G data they use, this makes our device require a CDMA LTE SIM(Verizon 4G LTE SIM or Straight Talk CDMA LTE SIM from the BYOP kit, the LTE version, not the GSM AT&T/T-Mobile kit). I'm actually the one that figured out that a SIM was needed for the ROMs to work. I can explain in detail, but I'll keep it short instead.
Even though our device is 3G and doesn't require a SIM under normal circumstances, with the SIM inserted in our device with those ROMs, we then have working mobile data and MMS, sometimes it requires setting APNs in the ROM along with using the SIM to get stock MMS working, otherwise, MMS would only work when using a 3RD party app for MMS.
A lot of people bricked this device trying to figure out why mobile data wasn't working before I discovered this SIM dependency. I've actually worked with a few developers trying to remove the SIM dependency so our device could use the ROMs without a SIM but nothing works, anything done to remove the dependency, kills all chances of connectivity, even call and text. I also helped with creating the first and only TWRP custom recovery specifically compiled for our d2tfnvzw(Tracfone on Verizon network Straight Talk S3) device. The other recoveries are actually d2vzw(Verizon Wireless S3) but they work on our device also, just not specifically.
The Straight Talk S3 can use the Verizon recoveries and ROMs because it is actually a rebranded Verizon S3(SCH-I535) and actually has the I535 model number stamped on our motherboards and other hardware inside our device, the only difference is that the 4G capability was disabled in the radio(no, using the 4G SIM will not give you 4G data). It is not "similar" to the Verizon S3, it IS the Verizon S3 modified for Straight Talk.
I can actually get you set up with some very good 5.1.1 Lollipop custom ROMs packed with features including working camera(we have marshmallow but front camera isn't working, that is always an issue with new ROMs because stock camera is closed source software, developers are not allowed to use it, they have to piece the coding together from scratch so it takes a while to fix), if you can get a used, previously activated Verizon 4G SIM($3-5 on eBay, used SIMs are better than new SIMs, new SIM gives aggravating issues) or Straight Talk BYOP LTE SIM. The ROMs are MUCH better than the stock JB 4.1.2 firmware. Let me know and I can get you setup and you won't even need the PC to do any of it. It can all be done with apps and your mobile browser. Using WiFi to download on the device instead of mobile data to download the ROM files you'll need, the apps that will flash the files you need are very simple to use. After the files are downloaded all you need is a click here and a click there and about 30 minutes of time and you'll be running something much better than stock with everything working as it should.
I have a guide posted here for flashing CM/CM based ROMs on our device and how to set up SIM and APNs, along with precautionary steps for your protection and troubleshooting steps for data issues after flashing the ROM and how to restore data connectivity if you do something wrong along the way.
If you do a google search using our model number, you'll find stuff everywhere that I have posted about this model number.
wow thats impressive stuff! i wish i could learn to do all that haha. I would love a working ROM on my s3 though, touch whiz is lame! i wont be able to buy the card till tomorrow because i dont have a card right now because i just moved to CT and had a bank that was only in TX and havent opened anything here yet, so ill have to give the cash to a buddy and have him order with his. I actually did the BYOP to straight talk as well when i couldnt use my s3 and i bought my friends s5, it had at&t, and thats where my straight talk service is on right now.. You have ROMs that would run on that by chance? Either one of them would be fun, I dont mind toying with the s3 a bit more though since its basically my side phone incase something happens with my s5.

The ST S5 is the Verizon S5 developer edition, the same as the ST S3 is the Verizon S3, the ST S5 is a Verizon rebrand also. Fortunately since it's a developer edition, that means it has an unlocked bootloader so that means you can safely flash the device with custom ROMs if there are any for the Verizon S5, I haven't looked but I'm sure it has ROMs(the other Verizon devices have locked bootloader and they will NEVER be able use anything but stock and modified stock ROMs, they can't use true custom ROMs like Cyanogen because it hard bricks the device because of the locked bootloader).

Im definitely going to be grabbing a used 4g sim. its the micro right? sorry if im buggin ya man, like i mentioned im real new to this and ive heard of ROMs and stuff before but never really seen them until i bought the S3 from my friend, and you are really knowledgeable about this so I hope you dont mind me picking your brain a little bit with these questions

Sorry, I misunderstood you, if your S5 came from AT&T then it is AT&T. I was saying that the Straight Talk version of the S5 is a Verizon S5 dev edition. AT&T is not. It will need to use the AT&T S5 ROMs if any exist.
There are a plethora of ROMs for the S3, they are all different so you'll have to check them out for yourself. OctOS 5.1.1 is my favorite and is the most stable and has everything working including front camera. I will have to link you to my copy of it though because it is no longer available for download on XDA. I'm using OctOS marshmallow right now but front camera isn't working yet.
To find the other ROMs, view this forum in a PC or mobile browser, find the Compact tab, click it, then find the Verizon SIII on the list, click it and it will take you to the Verizon S3 forum, then you'll see an Original Android Development and an Android Development subforum there. The ROMs can be found in threads in those two forums, use ONLY the ROMs that specifically say "d2vzw" in their names, do not use anything that says stock or TW or anything that mentions locked bootloader, modem, firmware, Safestrap recovery or Fashfire, that stuff is specifically for the Verizon S3 ONLY and will brick your device, read the threads, the first post in each ROM thread will list the ROM features and instructions for flashing(ignore these instructions and use the ones I link you to instead), but you'll need to be rooted and have custom recovery installed(my guide will explain how to get custom recovery).
Install the Towelroot app on your device, open it, tap the "make it rain" button and you'll be rooted.
Then go to Playstore and install SuperSU, open it to update the binaries.
Then, once you've found the ROM you want and its' compatible Gapps package(Google apps, the thread should mention which one you need), download them and put them both on extsdcard.
Then follow this thread to get a custom recovery installed, flash the ROM and Gapps and setup SIM/APNs. It is a very long guide but it is detailed step by step as simple as I could make it. Pay attention to the warnings and do the things I listed as safety measures for future reference.

Cool, just don't forget to use Towelroot or Cydia Impactor to root the S3 then install SuperSU, that must be done before you do anything else.
Let me know if you need anything.

Just rooted and downloaded supersu, I tried to pm you but its saying you aren't accepting them. I have one last question before I head to bed. I just realised, I can still flash a rom in here without the 4g sim still just won't have service, is that correct?

Sorry, I forgot that I blocked messages from the public because I was getting too many people asking for help. I have it set to only allow friends and forum administrators. Oops!!
There are older builds of Kit Kat 4.4.4 that can be flashed without SIM and everything works, but they probably aren't available for download anymore.
Yes, you can flash the ROMs just fine, you'll still have call and text, you'll just need to put the SIM in when you get it and reboot the device then set up the SIM and APNs like my guide says and then reboot again and you should be good to go, make sure you backup your IMEI(NVdata backup) like the guide says also, then be careful when you flash. If you flash and you lose all service including calling then don't do anything until you get in touch with me, if you make the wrong move from there, you'll make a mess that will be difficult to fix.

[Completed] S3 ATT Like to know how to unlock bootloader, root the phone, and install custom ROM

Hey first time posting on xda devs and would like to know how to unlock bootloader, root the phone, and install custom ROM.
Now I have spent entire day backing up and searching the different people root but if someone can help me and point me in the right direction that would be great.
So I have a S3 from ATT Model: SGH-I747, Version: 4.1.2 JellyBean, BaseBand Version: I747UCDMG2, Kernel: 3.0.31 - 1300972. It is a stock ROM, I have never done anything to the phone at all before.
Now I will admit I followed a youtube video call "How to Root AT&T Galaxy S3 SGH-I747!" by High on Android and I did everything in the video. I used odin v1.85, I did the PDA to the CWM.tar file, phone rebooted and I added the CWM superuser file and that is when I tried to get to CWM recovery mode and all I got was the phone's default recovery mode and not the CWM one.
From what I understand I believe I need to unlock bootloader first, but again this is a my first doing this and I hoping someone can point me in the right direction. Forum post state that you should follow guides that is exactly the same to the phone you would like to install custom ROMs.
Honestly I would like to ultimately be able to install a recovery mode that works with my phone that I am able to create snapshot image of my stock phone in case anything happens or I would like to go back to my stock image (which I highly doubt if everything goes fine) and install a custom ROM (I know there are different ROMs if someone can point me to where I can check out all the custom ROMs and not necessarily install those custom ROMs that would be awesome) and finally get rid of ATT loading screen when booting up the phone and install a custom boot loading screen, but of course I care more about getting the custom ROM install first.
If anyone can help that would be great.

Going back versions?
Ok, I'm pretty good on flashing ROMs and using TWRP. But I was thinking of trying a 5.1.1 Rom, I am rooted running just the stock Rom 6.01 currently. I have a SM-N900W8, so I assume I'll likely have to get the modem too depending on what ROM I choose.
My only concern is going backward, I don't know what kernel I might need to flash? Should be able to keep the answer simplistic in explanation, I just need the warnings and a basic checklist of what to do when going backward. And if I can complete this using just TWRP or whether I need to flash something with Odin or whether Flashfire might work.
Thanks in advance. Sorry I'm not a guy who has time to learn code. I try to donate if I'm going to use someone's work though. Just nice to have my phone run fast and smooth and be able to tinker...

Hi
What do you mean by 'going backward'? Do you wanna downgrade your device from Marshmallow to Lollipop? If yes, refer to this thread.

Ok, if going back to a earlier version of Android, then flash the factory full ROM of that version through Odin, then flash custom ROM of same version. Got it, thanks. Sounds like the easiest way.

Stuck N915G
Am using a N915G , it was rooted with CW recovery , since yesterday it would go in restart loop , so i went into recovery and did a reset , still the loop would not go , so i took into a service center they tries kies and it would intall lollipop but half way through it will show " erasing " and then go back to boot loop , now at this point when i re checked the phone there is no CW recovery , so i tried Odin with Marshmallow to flash the system , it shows PASS but during installation " System updating .. erasing " then goes back to reboot so i flashed new set of Pit files , but still the phone stays in boot loop , vibrates then goes off to loop , what am i doing wrong
Won't power on after normal power off.
Hi,
i mean; when i turn of the phone with normal shutdown menu, device power off normally.
But when i attempt to turn on device again, it won't turn on. nothing happens when i press or hold the power button.
only the way to turn on again, "plug a charge cable or usb cable"
after it detects the charge, and shows charging. after then i can turn on the device normal.
but, not possible to turn on without plug the cable once.
so; what can be my device's problem. (there is no another problem) except fast battery drain.
my opinion; humidity damage? or something like that.?
can any oxidation causes this problem?
please reply for help.
thanks.

Sent from my Motorola XT1080 using XDA Labs
Hello, I rooted my Samsung Galaxy Note Edge (N915T) Tmobile way back in 2014, I have since then forgot how to root again. I know that my phone is still rooted because I have SU.
My phone specs right now:
Bootloader: N915TUVU1ANJL
OS Version: KitKat 4.4.4
CPU: ARMv7-A (armeabi-v7a)
Kernel version: 3.10.0-2990579
I saw a post here in XDA about new Custom ROM (7.1.2 AOKP Nougat) and I would like to install custom ROM, and reading the instructions it states that it requires Bootloader 6.0.1 and Modem. I have no idea how to install bootloader and modem up to 6.0.1 on my phone. Kindly please guide me how to identify my current bootloader and how to upgrade up to 6.0.1. Thanks!
Hello,
I am using Odin v3.12.7 and I tried to select (twrp-3.0.2-0-tbltetmo.img) from Odin, but is not selectable because it does not have (.md5) or (.tar), where can I find a TWRP in those file formats?
What custom rom can i flush with my note edge sc-01g docomo japan,
Corrupt microsdcard and otg devices
Hi,
This is about my note edge N915G and what will follow has strangely happened with every kind of rom for the device stock rooted, aokp, customized stock, and slimroms.
What happens is
scard shows as corrupted after busybox/magisk7viper mods I mean the card is fine when I install busy box and magical and viper then in stall viper drivers and it is still good but when I reboot to activate the viper mods my card shows as corruption. I another thing that happens is when the card shows as corrupt, I I can try another card and still shows corrupt and strangely even the devices I connect through otg all show as corrupt. Ii think it is busy box which is needed for viper that does it, but am not sure.
Another guess is that maybe some embedded file on the phone has been deleted or corrupted and that is causing me the trouble. I have installed the Enhanced rom this evening and had set it up with closed root and magical. I it was all fine. I then I installed busy box using smart install and after that opened viper fx 2.5 and viper xhi=fi and each prompted to install drivers and they installed successfully and advised a reboot. It is after reboot that I opened my music player and found no songs which was be aise it is showing my card as corrupt. I strangely even if I reverse the process and uninstall viper drivers then viper apps and finally busybox it still does not change the status of the card. It is either that I install the rom again dirty or restore a system backup that was made while there were no add ons.
I would really appreciate if anyone can help figure this out as I do have the workaround of restoring system but it is tedious as I have to install all apps etc.
I would like to reiterate that this is not the kind of issue associated with Samsung phones in general where they are said to kill microsdcards. This is not the case and the card works flawlessly in a different phone which I did to check. My laptop too has no issues with same card it is a Samsung evo 64 gb card I'm using. Maybe they key is that even other as cards whether I put them in the card slot or in a card reader for otg it shows any card I use as corrupt and even my otg drives show up as corrupt. I think it is something I have never seen happening yet.
Thanks for reading this and for your suggestions and advice. I will look forward to your thoughts and inputs, knowledge and experience.

At&t Samsung Note Edge N915A 6.0.1
Hi I'm a noob. Last phone I "jailbroke" was a IPhone 3gs. Could you link me in the right direction to root my Samsung note edge from At&t 6.0.1 a list of procedures would be great, also a list of downloads. Anything & Everything I need on my phone or my Laptop to complete the process. All input would be appreciated. I just paid a large chunk of $ to Samsung to have my screen replaced and I am the original owner of my device which I paid a lot of money for in 2014, so I would hate to brick my device. Thanks
