I would like to un-root my Boost J7 - 2015 (SM-J700P) phone running MM 6.0.1.
SuperUser fails to unroot.
I'm thinking of flashing the stock ROM. I think I read here people where having issues with the phone booting or working properly after odining the stock rom. I don't want to mess up my phone, so I'm going to ask a few, I believe silly questions....... Better safe then sorry.
I found a link on here stating that the Boost J7 -2015 stock rom. It leads me to a link that has this zip filename. BST-J700PVPU1APB7-20160520115757.zip
Thread
This is one I found on the web somewhere, BST-J700PVPU1APF3-20160704162516.zip, but think this is the one I want since it matches the Software & Baseband Version.... or am I missing something?

Hello everyone, I've just recently switched from iPhone 4S to Android Galaxy S II
My phone info is given below:
Model: GT-I9100T
Android version: 2.3.5
Basband version: I9100TDUKJ1
PDA: I9100TDUKJ1
PHONE: I9100TDUKJ1
CSC: I9100TVAUKJ1
I have already followed the guide http://forum.xda-developers.com/showthread.php?t=1103399 to root my phone. I used http://download.chainfire.eu/50/CF-Root/SGS2/CF-Root-SGS2_XW_LUX_KJ1-v5.0-CWM5.zip and used Odin to flash it. I'm now having the yellow triangle which I want to get rid of. According to the instruction, it says "(4) Find an original Samsung signed stock kernel (preferably from the same stock firmware you have, but it's not terribly important)" however, the secure kernel link which I found from http://forum.xda-developers.com/showthread.php?t=1101671 does not seem to be listing any KJ1 version. Can anyone please provide me a link for downloading this? Would it be the one here?

Samsung Galaxy S II Stock Kernel for VODAFONE AUSTRALIA
I'm still not able to get rid of the yellow warning sign even after following the instructions given here.
http://forum.xda-developers.com/showpost.php?p=14283369&postcount=2
(4) Find an original Samsung signed stock kernel (preferably from the same stock firmware you have, but it's not terribly important)
(5) Reboot into download mode (adb reboot download, or boot the device with home and volume-down pressed)
(6) Fire up ODIN, and flash the Samsung kernel
(7) Boot the device with the stock kernel. CWM Manager will still be available.
I guess my problem is not having the secured KJ1 kernel. Would anyone be able to help me please? I'd greatly appreciate it!
Thanks in advance.
Bump?
Thanks a lot for the bump. I believe I'm after this file but the download link appears to be dead as mentioned by many others.

metalmaze,
Your best bet would be to download the stock firmware from Samsung themselves. Unlike many other companies, Samsung has a database where all (or rather most) of their stock firmwares are stored.
Since I'm unable to post outside links on the forum for now, do a Google search for "SamMobile firmware" and click on the first link. You will have to register in order to download any files from SamMobile, but it is quick and free, definitely worth it.
Hope this solves the issue! Best of luck!
[Q] Samsung galaxy S II GT-I9100T Stock kernel for Vodafone Australia
Hey |Shadow|,
Thank you for your reply. I'm very confused to be honest. I have downloaded the stock firmware file from sammobile firmware website where the filename was I9100TDUKJ1_I9100TVAUKJ1_VAU.zip. However, few questions remained unanswered because of which I didn't do anything with it.
1. This I9100TDUKJ1_I9100TVAUKJ1_VAU.zip is the original/stock firmware. What shall I use to put this inside the phone? Odin? or the CWM "Slash Stock firmware" ? Is there a difference in between these two methods?
2. If I install that firmware in the phone, wouldn't that unroot my phone again? If that's the case, then CWM will disappear and I'll have to put an insecure kernel again and then root it. So it'd be like back to square 1.
3. Although my phone is I9100TDUKJ1 running Gingerbread 2.3.5, can I use the insecure kernel hotfile.com/dl/145373032/054a67a/GT-I9100_JPKJ2_insecure.zip.html to flash first, root the phone and then use hotfile.com/dl/145373034/3731622/GT-I9100_JPKJ2_original.zip.html to get rid of the yellow exclamation mark? Would that work?
4. I'm asking #3 because I believe I've tried doing that and it did get rid of the yellow mark but when I launched CWM, it said the kernel version is different and many features have been disabled due to this.

Hey metalmaze,
Sorry that it took so long for me to get back to you, it took quite a bit of time to figure out exactly what you need to do to root the Samsung Galaxy SII (i9100 or in your case the i9100T) as I have the Samsung Galaxy S+ (i9001). With that being said, I think I found your solution
The stock firmware I told you to download is, in fact, only really used as a backup as you cannot (or at least not without great difficulty) separate the kernel and rom from the firmware. So if I were you, I would keep this file somewhere in case something ever happens to your phone and you need to restore it before sending it back to Samsung or Vodafone.
In the event that you have to flash back to the original stock firmware you can either use Kies or Odin (select as "One Package") and you should end up with a stock I9100T phone.
Now onto the topic at hand:
You have the KJ1 kernel on your phone at the moment and unfortunately there is no dedicated insecure kernel available yet, but there is another solution, or rather two:
1. You could use the KJ2 kernel:
hotfile.com/dl/143536280/cc63681/GT-I9100_XWKJ2_insecure.zip.html
hotfile.com/dl/143536361/ee49702/GT-I9100_XWKJ2_original.zip.html
or,
2. You could use the KI8 kernel:
hotfile.com/dl/143535921/572ad8d/GT-I9100_XWKI8_insecure.zip.html
hotfile.com/dl/143536103/be9ed09/GT-I9100_XWKI8_original.zip.html
If you look at the reference codes of Samsung: http://forum.xda-developers.com/showthread.php?t=800257 you will notice that KI8 is the firmware released just before KJ1, while KJ2 was released just after KJ1. Thus, both firmwares are extremely similar to the KJ1. The XW just means that it is an international firmware and thus you should not have ant problems with compatibility with Vodafone.
From other members on the forum, it seems that the preferable choice is the KI8 firmware, but as I said, you can use either.
I really hope that this solves your rooting problem! Best of luck!
Hi all
A week ago a rooted my Samsung Galaxy S6 device following this post: http://forum.xda-developers.com/galaxy-s6/general/root-pingpongroot-s6-root-tool-t3103016
All was OK. At that point my device is using the Android Version: 5.0.2
The question I have is that now the version 5.1.1 (Lillipop) has been released, I would like to know if my rooted device can still be upgrading when the new version is released in my region (Mexico) by the phone provider. (Telcel). In case it cannot be updated automatically, I guess I will need to do it manually or unroot my device. In that scenario, Does someone know a good tutorial how to do that?
Regards!
@LesthadMK, sure you can update rooted devices. But it may not be possible via OTA update. You will have to download the full firmware and install it manually.
Because root makes changes to system partition, OTA fails when you have rooted. If you unroot and flash stock recovery and kernel back, then OTA may work. Otherwise, simply flash the full firmware, in .tar format using Odin software, and you're good.
It's good to have full firmware saved on PC anyway, as if in case you brick your device, you can fix it by installing your device's firmware manually.
If you need help with 5.1.1 firmware installation on your s6, let me know the build no. of your device.. I will guide you to page you need to look at.
Thanks for the help. I have download Odin in case I need to do it manually.
Also, mentioned that yesterday I read an article saying that using the Samsung software "Smart Switch" in an rooted device will upgrade the device to the newest version (which I don't know if it it's true or not) Any way this is the link I found:.... Well seems since I'm newby I cannot post some external links. So just google it as: How to Use Smart Switch to Update Your Galaxy S6—Even It's Rooted.
By other hand, this is the build number for my device: G920IDVU1AOE3, so if you can help me to know how to upgrade that version that would be very helpful
Regards!
I want to change the firmware of my Galaxy S6 (SM-G920R6) which is Verizon LRA device. I want to Install a stock rom like the rom of SM-G920V or SM-920F or SM-G920T..
How can I do that? which firmware will be the best for it?
I want to change rom because APN refuses to work - I edited a lot of files, tried every suggestion from here & other forums - nothing helped .
So I decided to change the rom in order to enable APN edit.
So, how do I change the stock rom of my cellphone to another stock rom? The SIM is working propley after I change some settings in serivcemode (So it's not CDMA anymore, it's GSM).
Please Help ! :crying:
Edit : BTW I used this in order to root the cellphone - so maybe G920T firmware will work? CF-Auto-Root-zerofltetmo-zerofltetmo-smg920t
My android is 5.0.2, please help.
Anyone?
This is a little off topic for the op but I really need help right now.. I rooted with CF autoroot for G920F no problem then installed TWRP 3.0.2-1 zeroflteusc also built for G920F model and in the process of trying to find a better rom as soon as I had a custom recovery, me (being a dumba**) accidentally wiped my internal storage to do a clean flash of a rom therefore deleting the only backup I had. I've only been able to find the factory binary for this device which I flashed but it had literally nothing exept for basic testing software and a simple ui to run it. It was also stuck on Android 5.0.2 but I found a compatible rom with AllianceROM v1 with update v2 flashed for the G920F but I can't find any way to update past 5.0.2!! I've been trying to find a way to update somehow for weeks but nothing is compatible with my device and I'm stuck. Would someone that has my model running on Android 5.1.1 or 6.0/.1 please install the TWRP I mentioned before and make a backup of the system, modem, efs, and boot and post it online or send it to me it would be a lot of help.

that doesn't have all of the available firmware versions for the device
It just came onto my mind because of this thread here
http://forum.xda-developers.com/verizon-galaxy-s6/help/update-sm-g920v-vzw-sm-s906l-st-t3374291
and then there's also this
http://forum.xda-developers.com/verizon-galaxy-s6/general/downgrade-6-0-1-to-5-1-1-t3489816
Might be dumb, but was thinking of doing either of the 2. (The latter only provided a 5.1.1 rom/firmware that doesnt have a root breakthrough yet, sadly. Also wondering if I could downgrade it further to the 5.1.1 or 5.0.2 rom/firmware that already have root breakthrough)
Edit: Another question, where do I check this "OE2 or above" thing at?
Hi all, I'm relatively new to the Android world and seeking help from experts here.
I recently bought a used S7 (SM-G930K), it came with Android 8.0 and I want to downgrade to 7.0.
I tried downgrading using its stock firmware with Odin. Attempted many times but only realized that it can only be downgraded as far as the bootloader version goes.
Think my S7 was on bootloader version 2. So as checked for the available stock firmwares, the "earliest" version 2 was still on Android 8.0 (PDA G930KKKU2ERJ1 and CSC G930KKTC2ERJ1).
Anyone can advise me how to go about downgrading to Android 7.0? Though this S7 may not be my primary phone and there's obviously no warranty, I won't want to brick anything.
Do I have to downgrade the bootloader version to 1.0 first? And how do I do that?
Apologies, do excuse these noob questions, I'm not familiar with many Android terms. Cheers!
Model: S7 SM-G930K (KT Telco)
Android version: 8.0
Baseband version: G930KKKU2ERJ1

Basically, on Samsung phones, once you upgrade your bootloader, they put a lock on it, so you can never downgrade it, for security reasons, of course.
The only thing you can do is flashing custom rom, or stock rom with custom recovery & kernel.

I see, now i understand why..
"Custom roms" - does this mean it's made by users like us? And what does "stock rom with custom recovery & kernel" mean?
Can you point me where can i find these roms for my S7? Is it the same as flashing them on Odin?
Many thanks!
Yes custom ROM's are community made. The kernal is kind of like the foundation that sits beneath the ROM, so you can use the official ROM but run a custom kernal to tweak phone behaviour.
Flashing ROM's involves using TWRP instead of Odin. If you're going down that path I would recommend you read very carefully and educate yourself, instead of just gung ho'ing it. Wouldn't want to brick your device.
It's also worth mentioning while you can flash an older custom ROM via TWRP, that doesn't downgrade your bootloader with it. Having a newer bootloader on an older ROM can cause issues.
Most custom ROM's are also made for G930F, while some also support the G930K you may want to make sure before flashing anything.

Definitely will be more mindful as rooting does involve some kind of risk of bricking my phone.
Wow that's great info, really appreciate you explaining this to me.
Something new I've learnt! :good:
