The Ultimate Guide to Flashing a ROM on the HD2 (Windows Mobile)

Just thought i would share a tutorial i made about flashing ROMs
If this helps anyone in any way then i will be happy, i know there is already a few Flash guides out there but i wanted to have a go at my own.
Anyways if you find it helpful please leave a comment on the tutorial or if you have anything i could add leave a comment saying what it is.
Flashing a ROM is a simple procedure but for most the task sounds daunting. For those of you who are ready to take the leap and flash a ROM onto your phone i have good news for you. In this guide i am going to show you how to flash a ROM the easy way.
NOTE: This guide is based on the European version of the HTC HD2 (Leo) flashing process, flashing for other devices may vary. You must also make sure before starting this guide that you know which version of the HD2 you have so that you can flash the right ROM and Radio if needed. The European version of the HD2 has a 512 MB ROM and the US version has a 1024 MB ROM, the European version is also a little smaller than the US version and has less RAM, the US version has 576 MBs of RAM and the European version has 448 MBs. The US version also has a different Radio version that supports T-Mobile US's Frequencys. If you are unsure about which version of the HD2 you have then go to the Settings menu on your device, go to About Phone, and then look at Hardware information and Software information.
The first thing your going to need to check before you begin is that you have HSPL on your phone. If you don’t have any idea what HSPL is, take a step back and read up on it first. (Video on how to install HSPL) (XDA thread on HSPL with download link – For HD2 only) If your not using a HD2 then search XDA forums for the correct HSPL for your device.
Now that you have HSPL or for those that already had it, your going to need two things, a phone with Windows Mobile on it and a USB cable to connect your device to your computer.
NOTE: You may also need to update your devices Radio version depending on which ROM you flash.
So go ahead and plug your device in, a new screen should now show on your device. If not its probably because its your first time connecting the phone to your computer, don’t panic! just wait a while for the drivers to install and you should be up and running in about 20 seconds.
Select the Active Sync connection from the list.

}
And press done.
Now your device is connected properly you are ready to choose a ROM.
The best place to get ROMs is the XDA Forum. Point your browser to http://forum.xda-developers.com/ and then continue on to the next step.
The main page of the forum gives you a list of devices running Android and Windows Mobile and their respective threads.
Windows Mobile Forums are labelled with a Windows Mobile icon and Android Forums with an Android icon. Find your device and select the “ROM Development” Sub-Forum.
Once your in the Sub-Forum for your device browse through the ROM threads until you find a ROM that best suites you. For the sake of the tutorial we are going to choose the Energy GTX ROM.
As you can see in the screenshot above there are a lot of numbers involved. The only numbers you really have to worry about is the Windows Mobile Build Number. In this case its 21911 and 23673. The difference between the two is that a 21911 ROM has Windows Mobile 6.5 on it and a 23673 ROM has Windows Mobile 6.5.3 on it. There is not a major noticeable difference between the two Builds apart from the change in UI. In 6.5.3 the start menu, lock button and exit button are located at the bottom of the screen where as in 6.5 everything is located at the top, 6.5.3 also sports full multitouch support, threaded email and texting, Office Mobile 2010, the ability to drag and drop start menu icons and decreased page load time, improved memory management and gesture smoothing in Internet Explorer Mobile 6. In my opinion 6.5.3 looks better as it has a more up to date UI and on a device like the HD2 having everything at the bottom saves you a stretch. For more information on Windows Mobile Builds hit this link.
NOTE: Not all builds for 6.5.3 and 6.5 will have the same build number. However all builds with 21 as the first two digits will be windows mobile 6.5 and all builds with 23 as the first two digits will be windows mobile 6.5.3
Now you have chosen which ROM you are going to flash, you will need to download the files for that ROM. In my case the download link is on the second post of the thread.
NOTE: Don’t forget to check if the ROM needs a specific Radio version. Link to the HD2 Radio thread. For other devices search the XDA forum for your devices radio thread.
REMEMBER: Make sure you get the right ROM for your device and the right Radio version as flashing a Radio that is not for your device could brick it.
Hit the download link and save the file to the desktop. The file may be hosted of site but don’t worry, the sites are safe i assure you.
Once you have downloaded the ROM file you will need to extract it. In my case the ROM i downloaded was in the .7z format so i used WinRAR to extract it. WinRAR also works for .rar files and .zip files.
Now you have extracted the files you should have a folder that looks like this.
Inside the folder there should be two files, one .nbh file and one .exe file. If there are any other files in the folder you need not worry about them unless they are named “READ ME” or something similar to that.
NOTE: Do not move or remove any of the files inside the folder as it will cause the flashing process to not work.
The .exe file is the ROM flashing utility and the .nbh file is the actual ROM image that will be flashed to your device. Think of the ROM file as a .zip file and the ROM flashing utility as the extractor program which will extract it to your device.
Now we will begin the ROM Flashing process. MAKE SURE TO BACK UP ALL OF YOUR DATA AS THIS WILL WIPE YOUR DEVICE AND PUT IT BACK TO FACTORY SETTINGS. if you need a program to backup your data then i recommend using PIM Backup.
REMEMBER: Make sure your device is plugged in and set to active sync connection mode.
If your using XP run the .exe file which in my case is Leo_softwareUpgrade.exe and if your using Vista or Windows 7, right click the .exe file and choose run as administrator.
The ROM flashing utility will now open, read any warnings and click next.
Again read any warnings and click next
The utility will now take a few seconds to check the information on your HD2
The next screen will open after your information is verified. Click “Update” to proceed.
The next screen will tell you which ROM version you are currently using and which version you are about to flash. Double check that the ROM you are about to flash is the correct version and hit next.
The final screen will now show, read everything on screen and make sure you are ready to continue, if you changed your mind and don’t want to flash anymore you can hit the ESC to exit the program. Hit “Flash” to begin the flashing process.
NOTE: Once the flashing process has started you cannot stop it.
Once you have clicked “Flash” the flashing process will begin and a progress bar will appear onscreen.
REMEMBER: Make sure to read the warnings.
Your device will now restart and boot into the HSPL screen, don’t worry if this looks strange to you, its perfectly normal and safe.
If your device does not show this screen straight the way its probably because the drivers for HSPL mode are installing, be patient as this can time a while. Sometimes when the drivers aren’t already installed for HSPL mode the ROM Flashing utility may give you an error and say something like “Device not connected” or “Could not connect to device”. Don’t worry if this happens, just start the process again and follow the steps until you reach this point again.
The next screen you will see will look like this. So there should now be a progress bar onscreen on your computer and on your device.
NOTE: Flashing times may vary depending on the speed of your computer.
Once the flashing process has reached 100% you should see a confirmation on your computer screen saying “Congratulations your ROM update is now Complete”. Hit the finish button and you are done.
If the ROM has flashed successfully your device should restart and boot up as normal. Notice at the bottom of your screen it should display your new ROM version.
Your device may take longer to boot than normal but this is normal after a fresh ROM flash.
Most ROMs will have their own install screen so after the first boot screen you should see a screen like this.
The best thing about custom ROMs is that most of them have many of the usual settings already set up and skip unnecessary screens like the Screen Calibration setup and Typing Test screen.
The next screen that will show will be the carrier setup screen. Select the option that suites your plan and hit “Next”
NOTE: PostPay = Contract and PrePay = Pay As You Go
The next screen will confirm your selection and download the necessary settings.
Hit “Done” at the bottom when the download is complete.
The device will now load up your home screen, in my case that is GTX Sense.
And now your done! You now have a brand new ROM installed and set up on your device.

[ROM] [FROYO] EC03 Odin ROM

First things first, all credit goes to imnuts for bringing us Froyo! I'm not going to name this anything special, since all I did was download a little from the market here, delete and replace a little there, and make an Odin image. Since I can't in good conscience take any donations for this, if you're so inclined to donate to anyone, donate to imnuts!
This is a modified build of the stock EC03 ROM. I'll spare you all the boring details and just give the main points. As an aside, I take no responsibility if you brick your phone! I've tested this myself on my own Continuum with the actual uploaded ROM, so I can confirm that this works, unless you have already completely screwed up your phone! I have included the link to One Touch Unbrick for such a scenario (credit to AdamOutler)
- I've replaced the TouchWiz launcher with Go Launcher
- Stock browser has been replaced with Dolphin HD
- Bing, MS Streets, VZW apps all removed
- Google Search is the default, and Google Maps is included.
- I haven't figured out how to open Google Voice Search with a long press on the search softkey, but the softkey does open up Google Search
- When starting up, you may get a nag from Go Launcher. Don't worry, it will go away and you'll never see it again.
- For some odd reason, once the shortcut buttons for Go Launcher appeared in the wrong place. If this happens, tap Menu, Preferences, Operation Settings, and check Screen rotation. This will fix it, and you can disable Screen rotation if you'd like
Here's some useful links for what you'll need. This way, you don't have to go searching through threads to get everything you need. To flash, do the following:
1. Download the update.zip file and place it on the root of your SD card. It is probably best to do this first before flashing anything.
2. Place your phone in download mode by removing the battery and holding vol-down while connecting the USB cable.
3. If you want to do a NAND backup before proceeding, then flash just the CWM recovery listed below under PDA in Odin. Otherwise, proceed to step 4.
(a) Remove your USB cable, insert your battery, and power on the device while holding both the vol+ and vol- buttons until the Samsung logo appears
(b) To get into CWM, use the vol- to highlight apply sdcard:update.zip, and tap where the menu softkey normally is
(c) Once in CWM, the power button becomes select, and the back softkey is to go back. Use vol- to highlight backup and restore, select, then select Backup.
(d) Once backup is complete, remove your battery, and while holding down the vol- button, connect your USB cable. Keep holding until you are in download mode.
4. Unzip the ROM file to a tar.md5 file, select this file in Odin under PDA, and flash away!
5. Place the update.zip file linked below and boot into recovery by holding both volume buttons and the power button until you see the Samsung logo.
6. Once in recovery, apply update.zip. This is the CWM recovery, so you'll need to use the menu soft-key to select. Once in CWM, the power button is select and the back soft-key is back.
7. In CWM, make sure you do a wipe/factory reset and wipe cache partition, then reboot.
8. Profit!

The voice search works for me on the original EC03 actually it works surprisingly well. Me and a friend of mine were having some drinks and saying random stuff to it and it searched for what we said every time lol..

Yeah, it worked for me, but I didn't want the Bing voice search, I wanted the Google voice search. The voice search works on this modified ROM as well, but it's Google Voice Search. It just won't pull up with a long-press on the search soft-key. It works fine though within applications, and if you press the search soft-key, it pulls up the Google Search, and you can voice search from there. If I get bored this evening, I might create a stock Odin image from the original EC03. No promises though!

Doesn't selecting wipe/factory reset and wiping cache partitions totally just uninstall the mod?
Confuuuuuused LOL. I'll try it following your directions exactly (though you should put the "Place Update.zip" part at the very beginning. I foresee a lot of people getting confused on that lol) and see how it goes Thanks!

No need to get confused! I might just take your suggestion and edit my post. Flashing an Odin image is a lot easier than it sounds, and if you mess something up, there's always a way to get back to stock.
Even though Android devices have a single internal flash drive, there are separate mount points that are used by the OS with different permissions for each. Remember the underlying OS is essentialy a Linux/Unix derivative, and what you see on the UI of the phone is nothing more than a well designed GUI. That being said, the system partition/mount point by default is set as read only. When doing a wipe/factory reset, you are deleting all the user-defined parts of the OS, such as downloaded apps, email, contacts, calendar, etc. The cache partition is just that - a location where parts of the OS are placed when in transition, such as when updating an app that is part of the system partition.
When you root an Android phone, you are essentially unlocking the system partition so you can not only see what data is on the internal storage itself, but by using a file explorer that can make use of the root permissions, you can add and delete content to the system partition, which is how I made this ROM. Once I had everything the way I wanted it, I then extracted those mount points and combined them together into the flashable Odin image.
When you install a custom ROM, you are replacing the system partition located on the internal flash drive, and typically the recovery and kernel partitions as well.
I'm guessing this may be more information than you wanted, but I thought I'd throw it all out there to make things, hopefully, a little clearer.

That's actually really cool to know how you made this. Just in case, in the future, I want to make my own back up or whatever for it. Also, the rom works flawlessly. I was having problems with the other stock froyo rom until I flashed this on. My home and Search keys did nothing and I had no lock screen at all. I think it was just a random error when I flashed it, possibly because I didn't wipe the cache or something when I flashed the first time. Thanks a bunch buddy!

Awsome info....thanks
sent from my XDA phone - its more than a continuum

I'm glad to hear it's working for people. The only issue is bringing up Google Voice Search with a long-press on the search key, but heck, it's a very small price to pay to be rid of Bing.
Anyhow, here's a post for making your own Odin image. Like most everything I've posted lately, this too is courtesy of imnuts.
http://forum.xda-developers.com/showthread.php?t=1082288

I didn't even know you COULD voice search lol!

Yes, this does have Google Voice Search pre-installed. When tapping the search button, the standard Google Search app will open. Tap the microphone icon, and you have voice search.

Pretty good stuff, i'm not much of a fan of Go Launcher, other than that its really good.

just got this going and everything is running good so far. I have one question since this is a rooted rom is the native 3g hotspot free now or am i better off using wireless tether either way it dosnt matter my ps3 just picks up the 3g hotspot.

nvm i got it lol. i used wireless tether3.1 set profile to fascinate and enabled softap mode and my ps3 picks it up just fine.

Does the "Ticker" area still function like the factory version?
Will Flash Player 10 work?

This is too damn funny. My ROM made its way to Addictive Tips without me even knowing! I'm back to working on trying to improve this ROM. I don't know if anyone else is working on one, but my Eris is giving me problems, so I'll be keeping the Continuum at least until the last week or so of September.
http://www.addictivetips.com/mobile/install-android-2-2-froyo-custom-rom-on-samsung-continuum/

I have a list of some apps I'd like to see removed to make a super clean ROM. Let me know if you're interested.

I'm actually looking at doing that. I'm trying to get GoogleVoice working with a long press of the search soft key, but so far no luck. When I do get around to making another flashable rom, I'll be incorporating the Launcher for GB, and possibly removing a few more apps that I added in that some users may not want installed. It will definitely be a super clean ROM when I'm done!

got long press working with google search xD I'll upload it later xD
you have to do some smali editing to fix it, that's why it wouldn't work xP

Optimus F3 ROM

I can not find a forum for the Optimus F3, and do not know if this is the correct place for this. I rooted my phone and started cleaning out some of the bloatware that shipped with it. I managed to delete a few things that were important to the device. What I am looking for is a copy of the original(LS720ZV5) ROM that shipped with the device.
Thanks,
Buddy Ochoa

Please let me know what you deleted that was important im ready to delete the bloat on mine right now lol.

Here is the doc I wrote up on another site to restore the image. Note this is for VM/Sprint.
Flashing your LG F3 to Stock ROM. This will wipe out all data and applications and restore to out of box.
1) Download and install the stock drivers from LG’s site
http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
2) Download and install the LG F3 Flash Utility. Do not run the application after it installs. After the installation there is a MegaLock.dll file in the zip. Copy this over to the installation directory of the flash utility (C:\LG\LGFlashTool)
http://oudhitsquad.com/android/LGE/Firmware/LS720/LS720ZV5_00.zip
3) Create a folder on your desktop called LG
4) Download and then extract to the LG directory the Dll for the Flash Tool Utility
http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=CT109876368442163684421/[LGFLASHv151]LGLS720_20130509_Download.zip
5) Download and then extract to the LG directory the stock ROM
http://oudhitsquad.com/android/LGE/Firmware/LS720/LS720ZV5_00.zip
6) Power off your LG phone
7) While holding the up volume button, connect the phone to your computer via the micro USB cable. You should hear the USB connection activating and if this is the first time connecting it, will see a configuring device message (at least in Windows 8). On the screen of the phone you should now see “Download Mode” DO NOT UNPLUG the device until the process is complete.
8) Open device manager and expand ports (COM & LPT). Expand this and you should now see your com ports. Double click the “LGE Android Platform USB Serial port”.

Click the port setting tab, then the advanced button. Change the COM Port number to 41 like below. Click ok twice and close device manager.
This image has been resized. Click this bar to view the full image.
9) Next Launch the LG Flash utility. On the pop-up for the model config, click the “Select Manual Mode”. For the Dll, select the LGLS720_20130509_LGFLASHv151.dll that we download to the LG folder on the desktop. For the S/W select the ROM that we downloaded to the LG folder LS720ZV5_00.bin. Ensure that the connection mode is set to USB and the Upgrade DL is selected. Click OK.
10) On the main screen of the LG flash utility press the yellow right arrow button. When it says “Ready!!” in yellow, disconnect your phone from the USB cable. ***LEAVE THE LG FLASH UTILITY RUNNING ****
11) Disconnect the USB cable from the phone. Wait 5 seconds.
12) Connect the phone back to the USB cable. The flash utility should start updating the firmware and show a percentage. Once it hits around 85% the phone will reboot. You can now disconnect and close out of the Utility.

LG Tool
Hello,
Would like to know is anyone can help me out with this problem. Please not I am running Windows 8.1 pro 64bit laptop
I have installed the LG Flash tool kit. Followed directions. put phone in download mode and changed pot to 41 and MagaLock.dill was not in the download but checked and it was installed. Opeded LG Flash Tool and it says LG USB/Parallel Lock Key is not detected. So I click ok and brings me to a login box with country, ID and password.
Just do not know what went wrong. Thanks in advance for any help.

Hey Cris, I'm sure you've solved this by now but for anyone else, with the LG Flash Tool, you get prompts upon opening if you DON'T copy the MegaLock.dll into the application folder. Also, the first part about the Optimus F3 not having a category is a good point, it has enough posts to warrant one. Anyone know how to make it?

The url link to get your copy of the stock ROM for the Optimus F3 (LS720) (Sprint) on oudhitsquad.com is broken because the domain name is gone. Can you please re-post it somewhere else so we all can try it out? Also, any problem with using TWRP to install the ROM instead?

Yeah, can someone please reupload the LG F3 Flash Utility? Looks like http://oudhitsquad.com/ isn't coming back. The only other place I can find LS720ZV5_00.zip is some Chinese site where you have to pay to join.

I'm looking for a stock FreedomPop ROM also, my LG Optimus F3 LS720VSLR (LS720ZV8) is bricked and my backups (3 of them!) are all corrupt.

Hi everyone. I have everything to get these phones up and running again uploaded to https://www.androidfilehost.com/?w=files&flid=127434
Flash Tool w/megalock, LG Driver, Stock ROM (v7, take the OTA to v8, then root/install NoQ-Slide APK in place of original apk in /system/apps if you want)
You should also be able to just flash the stock rom and install the FreedomPop Apps to get back to the freedompop functionality. (these are the Virgin Mobile phones I have.
I've never bothered with TWRP on these phones - didn't have much luck with it a few years ago.
Hope this helps Let me know how things are going. I just dusted off these F3s and redid them for little handhelds. I have way too many phones ;(

Thanks for your uploads. I actually already found a stock FreedomPop ROM elsewhere. My FreedomPop phone came with TWRP 2.8.0.0 installed - the FP phones are already rooted. I don't know if any later versions of TWRP support this model.
Interestingly, I found that FreedomPop got a little too aggressive with de-bloating. Some missing lockscreen functionality (independent wallpaper and variable position pattern lock) can be recovered by installing the appropriate system files (LockScreen3.apk and LockScreen3.odex) from a Sprint ROM. This is a good security feature that IMO should not have been removed; if your lock pattern is always in the same place, it eventually becomes easier for someone to get into your phone by "reading" the pattern from wear on the screen or screen guard. I also restored a few other missing standard apps that I find useful, such as the generic email app, alarm clock, memo, voice recorder and weather apps.

Post #1 also now updated with a full in-depth REVIEW, enjoy

Very nice s7yler, that'sa good and interesting phone. When you sucessfully got root it, maybe I can try to theme the phone for you. Also made it on my HDC Note 3.

just ordered mine from DHgate, Excited:fingers-crossed:

Poor 3G reception.
Hi,
I've received my S2 4 day ago.
It's wonderfull, very little, fast enought...
But I've big problem with 3g reception: very very poor!
Only if it is closed to the cell bridge you have a good signal, otherwise it change in GSM mode.
Compared with my ZTE V970 (not a champion!) it have 15 dB less in 3G mode!
So it's unusable!
GPS and WiFi is weak too.
No problem in GSM mode.
Have you same problem?
Thanks.
EDIT:
SOLVED!!!
I've opened my phone, and view that internal side of film antenna for GSM (that's for 3G too) was a little crooked; I've detached and re-attached it properly. NOW MY PHONE WORK PRETTY-WELL IN 3G NOTWORKS!
It's not a champion of reception, but it's usable now!
I'm happy...
:victory:

3G depends on what frequency/network your carrier uses. It can be different from carrier to carrier or country to country.
Mine is always connected to 3G (here in Germany), but I agree that the signal is stronger with GSM only. GPS is ok, not the fastest though, the same with the WiFi, the range is good enough, but I also could wish the speed was faster.

Hi S7yler, could you send me some files?
The SystemUI.apk, on /system/apps. And the framework-res.apk and mediatek-res.apk on /system/framework, copy and send me if you can

Sorry S7yler, and thanks. I've forgot on 4.4 the /system changed a bit. I guess you can find the SystemUI.apk or LGSystemUI.apk on a folder called priv-app, inside /system.

Ok here
http://www.mediafire.com/download/ibcps7yv6sdwbmv/SystemUI.apk

Thanks S7yler, i've themed the SystemUI, to have the G3 look on Toogles of status bar.
If you want try, simply put this modded systemUI on the same priv-app folder, and set permissions to rw-r-r, maybe during the process the phone will reboot before you put permissions, but will but normally. Anyway, if you wanna try this. Have a good backup of your Rom in hands to flash if something goes wrong, and also backup the SystemUI.apk, you already has it on mediafire, btw it's up to you.
If you try this, let me know if you like, and show some screens. You can theme more the notification bar, with the XBlast tool for Xposed.

firmware ?
hello, anyone has the opportunity to find firmware for this device? and impossible to do root !! someone is successful?
thanks

The rom you can download from here kingsing.hk/services but S2 not avalible, among other.
s7yler how you root your S2 ? I do with difficulties "read back" method to read S2 rom and flash recovery, but I do it. Now I can't boot recovery, only factory mode...
With vRoot install vRoot apk, can't install supersu and root checker says "not root"
TowelRoot not work
How you root it? :good:

It rooted it via this guide from Itxtutor (with the read back method)
http://www.china-devices.com/Thread-100-Working-ROOT-CWM-Readback-your-ROM-with-SP-Flash-Tools
The complicated part can be to find the correct HEX numbers, and connect the phone so it begins the readback process. I did it yesterday and struggled almost 1 hour with it to connect correct and start the process, but it did work in the end. (the tricky part on that phone was that I had to hold volume UP down while inserting the battery and the USB cable, and then the readback process would start without any errors, before that it always stopped up with some strange BROM/DRAM error).
Also in step 8 in Itxtutors written guide, you need to flash both the patched BOOTIMG and RECOVERY, not only the RECOVERY (as his guide only shows). Else it will not work.
Also a tip is, if it SP Flash Tool crashes, then try another version of SP Flash Tool, I have 3 versions to try with. SP Flash Tool 3.1352.01, SP Flash Tool 3.1344.0.212 and SP Flash Tool 5.1348.00, and you can also try another USB port.

Thanks for your advice s7yler!
Yes I follow Itxtutor steps, but I flash only recovery and only boot in recovery line :silly: ... ok ok!
Preloader is no stable, on off constantly, I have tried different drivers ... I have tried volume buttons but not result
I use SP 5.1352.01
Method 100% - Battery inserted, plug USB, appears green battery, (now do it fast) unplug USB, battery disappears, push download in SP, plug USB
I flash recovery and bootimg separately, two times, both times without error.
Now I hope my CWM.... volume down factory mode, volumen up nothing. I try read rom again.
UPDATE
Finaly I rooted, mtk droid tools detected how root green (rootcheker no) and I use it to reboot to recovery (I can't enter only with phone) , without install nothing automaticaly appears supersu 1.86, root explorer,... now rootcheker says yes, I update supersu... root ok
Now I have other problem, when I disable usb debugging, phone restarts

Why disable usb debugging? just let it be on, it does no harm. I even heard that some phones (other models) should run better with usb debugging set to on.

Yeah thats exactly what I thought. I know it's not fine see one error like that on the phone. But just ignore it a lot of things and tool need USB debug and let it on forever will not affect nothing in the device

Thanks

s7yler, please make a backup of your rom, with mtkdroid, since you're able to perform root?
thanks

GT-P5210 stuck on boot screen after trying to root

EDIT March 11, 2016: Finally found a solution and no data was lost!
See post #5.
(is there no way to indicate on the thread that this is solved? I don't know exactly how it works on this forum...)
---------------------------------------------------------------
Hi!
So I've posted my problem on another forum but didn't get any reply, and I just realized I might have more chances to get faster replies on here.
Well, to make it short, I've tried to root my mothers' Galaxy Tab 3 (GT P5210), and as I've already rooted several devices (including another Galaxy Tab) without any problem, I didn't bother saving all the data on it... I'm afraid this was a big error.
I decided to root because it was getting stuck sometimes because of too many things running at a time in the background, and it made the tablet unusable until I reboot it. I wanted to install Greenify and make it work alone so my mother doesn't have anything to worry about but play without the tablet getting stuck. But I needed to root to use Greenify at its best...
As I've rooted several phones before, I know rooting doesn't wipe any data, unlike flashing seems to do. So I wasn't afraid of doing it.
I've followed this tutorial after installing the drivers.
Everything seemed to work correctly, Odin did what it had to do and it succeeded.
Though, now I can't turn on the tablet anymore: if it's turned on and that I press and hold the Power button, the "Samsung Galaxy Tab 3" screen shows up. But it doesn't move, it just stays here and does nothing.
I can turn it off, and try again, but the result is the same.
On the Internet I've read that charging it to 100% could solve the problem, but it doesn't seem to do anything as it was plugged all night and it's the same.
Now I've tried all combinations of buttons, because it was said that a second solution was to wipe the cache partition. But the only combination that works is Volume Down + Power, which brings the Download mode I had to get through in order to run Odin.
I've found this tutorial on here, but I don't even know if the correct word for my situation is "brick". And like many things I've found on the net, the tutorials for unlocking the tablet are for the tablets that have been flashed. But this is not what I wanted to do and I hope this is not what I did. And it doesn't inform if I'll lose data or not... which I'm afraid of.
I made the error of not making any backup before starting the process... I seriously hope nothing is lost.
Is there a way I can restart the tablet correctly again, even if I have to unroot, without losing anything?
Thanks by advance!

(sorry for the double-post)
No one?
Please, at least give me a clue on what I should do, or if there's hope to get back the data from it.

I don't know if you've lost data or if this method will wipe data, but it's what I used to root stock kitkat
Method
Also - I seem to remember that you should uncheck auto reboot, and after flashing is finished power off and back on
Good luck

Thank you for your answer.
The thing is that I've already gone through some steps of the tutorial I linked in the OP (until step 10 / step 11), and when the tablet was meant to reboot, it got stuck on the "Samsung Galaxy Tab 3" screen. I can turn it off and on, but it won't go further than this screen.
I can still bring up the Download Mode (by pressing Volume Down + Power), but there's no way to bring up anything else. Even the debug menu with Volume Up + Power (though I don't know if it was even available this way before trying to root). It will just load the boot screen and nothing more.
I'd try something with the Download Mode only if I can be sure that no data will be lost. If it may erase data, I prefer not doing it and to find a way to get it back before anything else.
Do you know if there's some way to access the memory?

Okay okay... I've struggled a long time with this problem, brought the tabled to a local repair shop but didn't find anything that couldn't risk any data loss... And finally I've found something, so I'll post my solution in case other people have the same problem.
Remember, I could only boot the tablet in Download mode. Every other button combination led me to the boot screen.
The problem was indeed the cache, that I needed to wipe, but without being able to access the Recovery mode there was no way to do it.
-------------------------------------
Solution:
First, I downloaded Odin 3.07 from somewhere else than from the link given in the tutorial (quick search on Google), because I had to untick Auto-reboot. Actually I'm not sure this is needed, but it worked for me with it unticked (while the version of Odin given in the tutorial doesn't let you untick it).
Then, download TWRP for P5210 (a quick search through Google led me to this ). Take out the .tar file from the .zip, but DON'T try to extract anything from the .tar file.
(basically, we'll "install" it onto the tablet using the same method as described in the tutorial)
Boot the tablet in Download Mode (Volume- and Power), choose Continue (Volume+ IF I remember correctly, but it's written anyway), then plug the tablet to your computer.
Run Odin, untick Auto-Reboot (as said before, not sure it's needed, but oh well, it worked...). Then click PDA, select the file you've downloaded (for me it was twrp-2.8.6.0-p5210.tar).
Then press Start, and wait (I waited approx. 2 minutes) until Odin displays "PASS!".
Now unplug the tablet, and turn it off.
Turn it on with Volume+ and Power, this time it will bring you to the TWRP menu (it asks to stay in Read-Only mode or not... choose no). Go to Wipe > Advanced Wipe, and tick Cache ONLY. "Swipe" to start the operation, wait, wait... then, once it's completed, press back until you go back to the main menu, press Reboot > System (then Swipe).
Now the tablet will boot normally. It won't be rooted, but at least it will work again, and fortunately, without any data loss.

You couldn't flash super user from TWRP?

I have the same issue, my Tab 3 is stuck on the Samsung logo.
And the Odin is stuck on the file mentioned above.
Can someone please help?
