[Q] Another firmware question - Samsung Galaxy Tab Plus

I bought a US refurb P6210, I am in the UK.
Using Kies it doesn't state a current firmware version - is that a problem?
It also states there are no updates available - fine if true, not needing one.
How do I know what software I am using so I can get a Stock image for recovery purposes?
Android Version: 3.2
Kernel: 2.6.36-P6210UEKJC-CL567728
Build: HTJ85B.UEKJC.P6210UEKJC
Which doesn't seem to tie up with any of these:

It looks like I have a North American firmware October 2011 version C
The guy below me has European firmware Dec 2011 version 4

I too seem to have an unknown Firmware
Model: Gt-P6210
Android: 3.2
Kernel: 2.6.36-P6210XXKL4-CL604657
[email protected]#3
Build Number: HTJ85B.XXKL4 P6210XXKL4

UEKJC to UEKL1
Has anyone succesfully flashed the full P6210UEKL1 package over the P6210UEKJC firmware?
I'm starting to think UEKJC is a very early or slightly unofficial firmware as Kies doesn't recognise it (Current firmware version: BLANK) and the OTA never finds any updates.
This seems to be the firmware coming on the US refurb units from Digigood on eBay.
I'm tempted to start from fresh and flash UEKL1 using Odin and then see if Kies and OTA start to pick up the real updates from there.
For Odin flashing would this be the right process?
1. Start Odin 1.85
2. Load P6210XARKL1_P6210UEKL1_HOME.tar.md5 into PDA section
3. Turn on P6210 with Power and Volume Down and choose Download mode
4. Hit Start on Odin
Any advice/help appreciated

Yup. That's the correct process. This should bring you back to stock. I don't know what's been done to your tab's ROM in order for KIES not to recognize it, (I'd probably need more information, but it's not at all important,) this process should give you a clean slate from which to start. Good luck!

[Q] Galaxy Tab GT-P6210 Firmware Update?

Turned on my tab this morning before work and after a few minutes a pop up displayed a message indicating a firmware update was available. Didn't do anything 'cause I'm rooted and customized and wasn't sure CWM would remain to get me back to where I was. Looked here expecting to see everyone talking about it and disecting it and am suprised to see nothing. Maybe this is old news and I missed it? I keep this site up on a browser tab 100% but it is still possible. I searched and went back a few and didn't see anything. Anyone else getting this?
i saw the update late last night, and tried to do it, but it kept giving errors when i tried to install it both from kies and ota. My firmware wasnt listed in the stock firmware list so i used odin to put in stock firmware, amd now the update isnt showing.
The update was 150mb and said something about updating the market.
Heres hoping i didnt delay ics for myself
On my end both kies and the built in updater are telling me there is no update so maybe something strange happened on their end? Or maybe they are getting ready to release it
150MB? doesnt sound like ICS. I would expect it to weigh in over 400MB. Hopefully Im wrong. Maybe its some "prep" update to fix someting for the coming ICS.
What build number are you on? The latest for the P6210 is LA3. Since you can't update with a custom recovery in place you may be behind a version or two and thats why Kies is telling you an update is available. To get any update, including ICS, you will have to put the stock recovery back, this is all covered in Gary's post for rooting and installing CWM Recovery. No device I know of will accept a carriers or manufacturers update with a custom recovery in place.
My GT-P6210 is stock, and neither Kies nor the device shows a firmware update. Kies says current firmware is PDA:LA3/CSC:LA3 (XAR).
I'm not sure what firmware I was last night. I did a search for the firmware version it said I had, but I was only able to find one or two references to it.
I am currently on LA3 and not seeing any updates available.
Yeah, I feel like an idiot. I upgraded to LA3, couldn't use Gary's kernel (and I had to have it for my project) so I downgraded with my nandroid. I used Kies to get the upgrade, was not prompted, and forgot about it. So...sorry, fellas! False alarm. Feel free to ignore my future outbursts.
The P6210 I purchased earlier this week came with LB2. Is this newer or older than LA3?
LA3 is the third firmware build in Jan 2012. LB2 would be the second build in Feb of 2012 (so LB2 would be newer.)

I supposed it is not possible to extract the ROM file out of the tablet, as I didn't get any response here.
Could LB2 be for Canada only (since ikeny's P6210 was bought there)? Would that explain why U.S. customers aren't seeing it as an available update?

Could be. But interestingly, there is no "English (Canada)" or "French (Canada)" in the language selection. Hopefully it's not any hardware differences.
[Update] In the other thread about the IR port, it's been pointed out that the Canadian version does not include the IR port. I don't get Samsung, it's like they think the fragmentation problem is not bad enough (GTab 7, 7.7, 8.9, 10.1, 7.0+... ), they want to introduce more different variants (P6200, P6210; now P6210 with IR and without IR). No wonder why it is taking so long to release ICS for all these devices !!!

Kies wont' display my firmware version, which is annoying. Can I find out from the device itself? Navigating to About Device shows no "firmware" but mentions "Kernel Version: 2.6.36-P6210UEKJC-CL567728 [email protected] #3" with "Build Number: HTJ85B.UEKJC P6210UEKJC". What the <bleep> does *that* mean??

KJC:
K == 2011 (K is 2011, L is 2012, M will likely be 2013)
J == October (10th letter of the alphabet, 10th month of the year..)
C == 12th revision (1,2,3,...8,9,A,B,C,D)
hmmm, not as recent as LB2 then
I guess I could always take it to an authorised service centre for an official firmware upgrade...
A couple of quick questions:
1). My GT7+ build number is P6210UELA1 and it's rooted with Gary's method. Will the firmware update remove the root?
2). What does this firmware fixed? The only problem I have are:
- Lag after using the device for certain time (moving screen, etc.)
- Apps that are tablet-optimized is not shown as such (Mint, TripAdvisor) and shown in "phone" mode.
1. AFAIK, none of garyd's root options are compatible with standard firmware updates. Someone please correct me if I'm wrong.
In order to upgrade your firmware, you'd need to restore your tablet to stock first and then upgrade to the latest firmware.
2. AFAIK, the issues you are experiencing will not be remedied by updating the firmware.
Thanks for the information. Do you know if I can re-root once I downloaded the latest firmware? I.e. download latest firmware, lose root, with new firmware re-root.

Yes.
Before I recently switched to an older firmware (so that I could use garyd's custom kernel), I had updated to the latest LA3 and rooted using p6210_CWMR_20120107.zip from [GT-P6210][CWMRecovery][ROOT] ClockworkMod Recovery and Root (07-Jan-2012). My tablet was running fine.

[Q] Regarding stock kernel for Samsung galaxy S II Vodafone Australia

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?

I'm still not able to get rid of the yellow warning sign even after following the instructions given here.

(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.

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.
[Q] Samsung galaxy S II GT-I9100T Stock kernel for Vodafone Australia
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!

Make sure that Samsung KIES is comleptely disabled or uninstalled.
Connect your phone in "DOWNLOAD" mode (Power off, then press "Vol down + home + power" at the same time)
Run ODIN and select the downloaded firmware (.tar.md5 file) as "AP"
Press start and wait about 15 minutes for ODIN finishing the installtion.
All of your personal data may be deleted when installing firmware using ODIN (Depends on phone and firmware)
after odin finishes do i need to volumn up to apply update or will changes occur when it auto boots? Many thanks

Flashing more recent stock rom from sammobile

Hi
Apologies for what is quite a basic question for I'm just trying to get things straight in my head before proceeding.
I have a UK retail S7 G930F, current running stock
Build G930FXXU1DQC4
Baseband G930FXXU1DQC2
Despite the fact this build only has Android security patch level February 2017, and the latest build is from 2018, my device and Smart Switch insist I am up to date, I want to actually make this the case while remaining on stock firmware.
I have used Odin to flash Galaxy phones before but not since I had a Note 2 and Note 3 so I'm a little rusty.
I have Odin 3.13.1 and the zip download from sammobile for build G930FXXS2DRAA for the same CSC region I'm currently on which is XEU.
All the guides for Odin flashing say to only use the AP file and option in Odin. However as my BL, CP and CSC will all be older as well, and I'm simply going from stock to stock can I (or should I) also flash these parts as well?
Thanks.
I need more information. 6 mm and 7 nougat use the same BL and require no upgrade where if you were on lollipop somehow you would need the bl. Please DO NOT run off and start flashing things like BL without help from here first. I have bricked a samsung device so bad I had to replace the motherboard, so I learned the hard way.
Both current firmware and the one I intend to flash are Android 7, the new one is just a much more recent build with a more up to date security patch level.
My current firmware, as shipped (or possibly updated OTA a long time ago)
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XEU/download/G930FXXU1DQC4/127501/
My intended firmware that I plan to flash
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XEU/download/G930FXXS2DRAA/205600/
Despite the fact that sammobile says the newer one is available in Smart Switch, it doesn't show any updates when I connect my device to my PC with Smart Switch.

I get that a lot. I upgraded my s7 to latest n release today and it worked ok.
So, do I just flash AP or everything?

You need to flash all 4 files: BL / AP / CP / CSC
I do recommend that you flash CSC* and not HOME_CSC*. That way you will reset the phone to factory defaults and it will be ready for future OTA updates.
Backup your files first that you think are important and then start from scratch to configure the phone, install your apps, update the ones on the phone.

[Guide] How to downgrade from Android Oreo 8.0 to 7.0 (Non-rooted)

How to downgrade a non-rooted S7 Edge from Android Oreo 8.0 to 7.0 and keeping your Knox 0x0!
So if some of you are looking for a 'how-to' guide, look no further! ​(I believe it works on your S7 too, but make sure you have downloaded the correct firmware)​
*IMPORTANT*
-I don't take ANY responsibility if you bricked your device during the flash!
-Follow the guide below before flashing your official firmware using Odin!
On the phone
-Sign-out any accounts on settings
-Have OEM-unlock & USB Debugging ON (developer options)
-*optional task, just in case* Screenshot your device information on the settings tab (IMEI, Baseband, Software Info, Model number)
-*optional task, just in case* Backup your device using Samsung SmartSwitch software
Things to download
-For this guide I used Odin v3.13.1 https://dl.sammobile.com/Odin3-v3.13.1.zip
-You can install the Samsung driver using SmartSwitch if your Win PC can't detect your Samsung phone (it should show on Device Manager > Modem > something like Samsung Modem)
-*READ* You can't flash back to version 6.0 now because of (Android Oreo 8.0 is using different version of boot-loader) but there are some late Android 7.0 with updated boot-loader, those are using boot-loader binary v2, so binary v1 it will be conflicted and won't work upon flash.
-*NOTE* Download the correct firmware of your phone model by following the baseband, that's why I recommended to take screenshots of your phone, you can search it on here https://www.sammobile.com/firmwares/, for mine, I've searched SM-G935F and BTU is my choice, the filtered results should be your correct firmware. But in my case I used (v7.0 in March 2018) because it has the binary boot-loader v2 with it (whatever it called, it's important otherwise it will not work which I've tried)
-*optional*, if you find sammobile download speed is way too slow* You can use https://updato.com/firmware-archive-select-model?q=SM-G935F&exact=1&r=&v=Nougat%28Android+7.0%29%2COreo%28Android+8.0.0%29&rpp=100, and basically look for the correct firmware which I have mentioned above.
-Extract your firmware onto a single folder, don't mess them up! (you should see something like AP_G935blahblahblah.md5, and you will need AP_, BL_, CP_, CSC_ for downgrading)
Follow the steps:
1. Now you have the correct firmware and Odin running on Admin right
2. On Odin you can add AP_, BL_, CP_ & CSC_ onto the correct selection, for example: https://i.imgur.com/DIB2d1S.png
3. Have your phone on Download mode, google it if you don't know how (make sure you followed the On the phone step first, it's very important)
4. Find a data USB cable and plug into USB2.0 port, make sure your phone appeared on Odin (you will see something like 0:[COM5])
5. On Odin (only Auto Reboot, F. Reset Time) is needed, it should be ticked by default.
6. Now you can safely click 'Start' on Odin.
7. DO NOT TOUCH YOUR PHONE in case your USB is loose which I had experience before.
8. Wait until it shows a green PASS! like this: https://i.imgur.com/FYosmx2.png
9. When see a blue screen with Erasing text on it, please wait until it reboot and hold (Volume UP + Home Button + Power Button) boot to recovery mode
10. Wipe cache partition, and data/factory reset then reboot system now
11. Wait for it to boot into your sweet sweet Android Nougat 7.0 (Late version)
12. Disable auto-update if you wish, mine was on auto-update so I had to pause it half-way
Hope you find this guide helpful, I tried to remember the steps on my head as I typed, (*sorry for the grammar if you find it hard to understand) and if you think I've missed something here, let me know! I would update the guide if any step is missing, just in case
Thanks

Help with G930A
Hello um I have a Samsung Galaxy S7 on AT&T (G939A) and it's on 8.0 (G930AUCS9CSB1). I've tried to root it but after some research I've come to find out I have to downgrade it to nougat to root it. But the problem is everytime I load a firmware it fails and I did more research I think it said something about the bootloader blocking it and the only way to downgrade the bootloader is downgrading the firmware which I can't do because of that cycle. Can someone please help me all I want to do is root install a custom recovery and a custom rom I love playing around with android tweaks but I can't get it because of this. I hope someone can help me please and thank you.

Your bootloader cannot be unlocked due to it being Snapdragon, so unfortunately there is nothing you can do. Only Exynos variants can be modified.
Hello guys,I have a problem with my galaxy s7 sm-g935f(Exynos version).Few months ago I flashed my phone from android Nougat SEE CSC(South East Europe) to UK's Oreo BTU CSC.I'm curious is there any other way to downgrade it from oreo to nougat,otherwise than Odin.I tried flashing it a few times with the latest Odin version (3.13.3) and nougat SEE CSC(South East Europe) because that's my original CSC.Odin recognizes the device normally,but when i click start,it comes to setup connection and then FAIL.The reason I'm trying to downgrade is very poor battery life and heating,and the phone is very laggy.I even tried through Samsung Smart Switch Emergency software recovery but it seems that Samsung has restricted that option...please help if anyone has/had similar problem.Thank you!
Mine is Sprint g935pvpsbcta1

So if some of you are looking for a 'how-to' guide, look no further!
(I believe it works on your S7 too, but make sure you have downloaded the correct firmware)​
*IMPORTANT*
-I don't take ANY responsibility if you bricked your device during the flash!
-Follow the guide below before flashing your official firmware using Odin!
On the phone
-Sign-out any accounts on settings
-Have OEM-unlock & USB Debugging ON (developer options)
-*optional task, just in case* Screenshot your device information on the settings tab (IMEI, Baseband, Software Info, Model number)
-*optional task, just in case* Backup your device using Samsung SmartSwitch software
Things to download
-For this guide I used Odin v3.13.1 https://dl.sammobile.com/Odin3-v3.13.1.zip
-You can install the Samsung driver using SmartSwitch if your Win PC can't detect your Samsung phone (it should show on Device Manager > Modem > something like Samsung Modem)
-*READ* You can't flash back to version 6.0 now because of (Android Oreo 8.0 is using different version of boot-loader) but there are some late Android 7.0 with updated boot-loader, those are using boot-loader binary v2, so binary v1 it will be conflicted and won't work upon flash.
-*NOTE* Download the correct firmware of your phone model by following the baseband, that's why I recommended to take screenshots of your phone, you can search it on here https://www.sammobile.com/firmwares/, for mine, I've searched SM-G935F and BTU is my choice, the filtered results should be your correct firmware. But in my case I used (v7.0 in March 2018) because it has the binary boot-loader v2 with it (whatever it called, it's important otherwise it will not work which I've tried)
-*optional*, if you find sammobile download speed is way too slow* You can use https://updato.com/firmware-archive-select-model?q=SM-G935F&exact=1&r=&v=Nougat%28Android+7.0%29%2COreo%28Android+8.0.0%29&rpp=100, and basically look for the correct firmware which I have mentioned above.
-Extract your firmware onto a single folder, don't mess them up! (you should see something like AP_G935blahblahblah.md5, and you will need AP_, BL_, CP_, CSC_ for downgrading)
Follow the steps:
1. Now you have the correct firmware and Odin running on Admin right
2. On Odin you can add AP_, BL_, CP_ & CSC_ onto the correct selection, for example:

3. Have your phone on Download mode, google it if you don't know how (make sure you followed the On the phone step first, it's very important)
4. Find a data USB cable and plug into USB2.0 port, make sure your phone appeared on Odin (you will see something like 0:[COM5])
5. On Odin (only Auto Reboot, F. Reset Time) is needed, it should be ticked by default.
6. Now you can safely click 'Start' on Odin.
7. DO NOT TOUCH YOUR PHONE in case your USB is loose which I had experience before.
8. Wait until it shows a green PASS! like this:

9. When see a blue screen with Erasing text on it, please wait until it reboot and hold (Volume UP + Home Button + Power Button) boot to recovery mode
10. Wipe cache partition, and data/factory reset then reboot system now
11. Wait for it to boot into your sweet sweet Android Nougat 7.0 (Late version)
12. Disable auto-update if you wish, mine was on auto-update so I had to pause it half-way
Hope you find this guide helpful, I tried to remember the steps on my head as I typed, (*sorry for the grammar if you find it hard to understand) and if you think I've missed something here, let me know! I would update the guide if any step is missing, just in case

Click to collapse
I just wonder this solution will be work as well? my phone is s6 edge plus G928C.
And i want to downgrade to 5.1.1 or 6.0 because 7.0 was really terrible.
