First of all I just want to say WOW what an insightful and creative community you guys got going on around here. A lot of smart people on these boards. Thanks for the resources you guys provide to make having a cell phone into a hobby.
I have just successfully rooted my phone after hours of deduction and have flashed RC33 and a radio ending with 1.1. I've spent about 4 hours getting to this point and still feel behind the game. What motivated me to do this was the Official Hero Rom in the Android Development Thread and that is my ultimate goal insofar.
However, now that I've done this I don't want to take any unnecessary risks. I've used the dandy search feature and done hours of research as well as lurk on here since the launch of the G1 when I picked up the phone on launch day. I know about all of the informative links and they're great and I've reviewed them thoroughly but am still fuzzy on a few things.
I've read that there are different types of SPL's some brick and some don't. Please correct me if I'm wrong but my understanding of an SPL is that it is basically the update.zip file in my SD card. Currently that is a build of RC33 in my card along with recovery.img. For some reason I feel that this is not all as far as an SPL is concerned. If someone can concisely clarify this for me that would be great.
Also before I jump on Hero, what is a good cupcake ROM around here that is stable and not lacking many features that can easily be blinged out with one of the awesome themes you've got floating around here. I'm open to all enthusiastic suggestions. What tips do you guys have for me to move up to one of those?
I have not even begun to delve into App2SD or Nandroid but am getting a clearer image as to what they are and how they function. Any helpful tidbits on the two subjects would also be greatly appreciated, however they are not my main concern immediately.
Again thanks guys I've got work in about three hours now lol so I'm going to get some shut eye however I'll be back tomorrow. Soon, I hope to contribute to what you guys have got going on.
Unfortunately your hours of deduction did not lead you to this thread. Which has a link to this thread. Which has definitions, two I am posting here:
Bootloader – the SPL and IPL of a flash based device. See jashu’s description here.
SPL (Secondary Program Loader) - You get to the SPL by holding the camera button while powering on your phone. This is where you flash NBH images. See bootloader above.

Which links you to a greater explanation of what the SPL is.
Personally, I don't think the Hero builds compare with Cyanogen's Scary Experimental builds. I believe you sacrafice a lot of speed to gain very little (if any) functionality. Don't let the misnomer of "Scary Experimental" throw you off. His latest 3.5.3 blows everything else away. It's within a build or two of being declared stable. And most of the tiny little issues with 3.5.3 can usually be fixed with instructions being posted in that thread.
Moving over to Cyanogen's 3.5.3 is braindead simple too. Don't rush, follow the recommended upgrade path, and you'll be set. It does all the work for you, and it doesn't require the sometimes dreaded new SPL (which, BTW, is not nearly as risky as some will lead you to believe ... you just have to properly follow the required steps). Still, will this being your first attempt at any of this, you'll find it much less taxing on your nerves by sticking with a more straightforward upgrade. Cyanogen's is a great way to get your feet wet. And in the end, you'll end up with a blazing fast phone with all the bells and whistles too. Your phone will impress the moment it first boots. There are themes available now, and more will be coming once it hits stable. Apps2SD are automatically done for you if you have your sdcard formatted correctly. There are a myraid of ways to get the correct partitions on the sdcard, so do that before anything else. It will increase your chances of making this successful on the first attempt. Remember that a wipe is not necessarily a bad thing, it's usually that a failure to wipe is what caused your problem in the first place. Wipe if it's recommended. Read the comments to determine when it required, when it's just a recommendation, or when it's not necessary.
Be methodic. Since this is your 1st attempt at this, you'll be doing yourself a huge favor if you grab everything you need all at once. Don't try to take any shortcuts, follow the steps or instructions to the t. Make sure you have the latest radio installed (and the new SPL should you pick a build that requires it). Although they usually list the latest builds in the 1st post of a particular topic, occasionally they will release in intermediate fix within the thread itself. Check the last few 10 or so pages of comments for your build of choice to see what build is recommended at the time. Usually, you'll want to grab the latest build, but that's not always the case. Bleeding edge is not always best (althought with C's Scary Experimental, I've eagerly awaited each and every update because it's only gotten better each time).
Since you've done your research, go back and outline the entire upgrade path. Write it down for reference. Make sure your Windows driver are up-to-date, have the latest ADB installed on your computer (it makes things much easier if you use ADB if possible), don't do anything until you can devote a couple of uninterrupted hours to the upgrade process, and I cannot emphasize enough to WIPE as necessary. Hell, don't install any programs or fiddle with any settings. WIPE each step along the way until you get the final build installed. If something doesn't seem right any step along the way, don't proceed to the next step. WIPE again and re-flash. See if that fixes your problem. If it does, the proceed. If it doesn't, see if it's an issue that fixed with the next build you'll be flashing. If so, proceed. If not, look for another solution. Proceeding at that point _might_ be okay, just be aware that you might get yourself into a situation that requires re-rooting your phone.
Make sure that before you do anything else that you have one of the modified recovery images flashed to your phone. They're modified for a good reason.
If things go bad, don't panic and start posting that you've "bricked" your phone. Chances are you haven't. Very few phones get "bricked" to a point you can't fix it yourself. When people around here see the term "bricked" as a subject in a post's topic, it's a red flag that becomes a red herring for you. You may get into a boot loop or something, but it's usually fixable with a WIPE and an update.
Also, keep DREAIMG.img in the root of your sdcard at all times. Don't move it, don't delete it, don't rename it. It can, and will, save your ass if any of this hits the crapper. Carry it with you at all times. If you have DREAIMG in the root directory, you'll always be able to get your phone back to an operating condition, wherever you are, whenever you might need it, without the need for a computer. Yes, it would be starting all over again, but it would give your phone basic functionality if all goes to hell and you're not near a computer or don't have a USB cable or something.
None of this requires a PH.D. It's actually quiet simple. Most people that run into problems have simply missed or skipped a step, or failed to wipe as required. Knowing recovery proceeds in advance will be helpful, but even that is pretty straightforward and easy to follow. I've done all these flashings, re-flashings, recoveries, etc., so much that I --think-- I have the terminal commands etched in my memory. And I do. But I still refer to the on-screen steps to make 100% sure I'm typing things correct. I hit enter only after I'm confident I didn't type a 0 when it should be O (hehe). I look at the screens during the whole process for indications of success or failure. And I make sure that I am not distracted by anything when I upgrade. Lock yourself in a room by yourself after you've emptied your bladder. If you do get interrupted or have to take a bathroom break, write down the next step. Don't assume you'll remember. And don't even think of making or taking phone calls until you've finished this whole thing.
Read in advance.
Search as necessary.
Ask, in the appropriate forum and thread, when all else fails.
You'll do fine.
Good luck.
The SUPER Custom Rom Guide and Troubleshoot
There came a new version, your droid got old school and there is no support from Samsung cause they have forgotten about you.
Service centers you looked upon, and to mention exorbitant fees plus service tax came along. Thank You ma'am. will see you around.
Your droid is lagging and hanging and Lo, stops working suddenly. Now you just want to try something new, cause you can't sell them or buy new.
You search on google,
find on Youtube,
Read between surveys and blogs,
tried it yourself,
sometimes got lucky sometimes got thorny.
Now you come to the XDA community. there is too much to absorb and you're kind a new, welcome to all of you.

Dealing with most of the trouble making bugs and useful insight into cornering them like a rat
1. Tab is Stuck on Charging Screen. Tab is not turning On, battery completely depleted/Not charging, Nothing is Working
2. Stuck On Samsung Logo Screen.
3. Stuck in a Boot Loop.
4. Stuck On Firmware Upgrade Encountered an Issue.
5. Bricked.Explained in Post number 2
Well that would sum up for me and most of the users will agree that these are the cases that really needs attention and no cussing about how your droid lags and hangs, doesn't makes it to the lists So, by the end of this guide, I would hope and expect at least so much from users to at least have a better knowledge and general idea of how things work here. so users don't just go on saying HELP HELP I am a NooB, Please read and understand first, dude. Thank you I will try to make it simple even if you're not so cool.
A few words about me if you're interested
OH!! you clicked!! wow. well what should I say here. ahem, hello gorgeous. I am Sam So, unlikely,
So guys, I wasn't lucky enough to get everything organised at one thread and spend a lot of time finding a perfect place for everything I would want to, so I thought this would be worth a share. It took me almost a month to write this stuff. yeah I was bored to the core, so put in some fun stuff
along with most of my learning experience and knowledge gained here on XDA in this Guide over the span of 3 years, I would just read and experiment it myself, kind of guy, I wouldn't have dared to put up this guide sooner, but now after successfully solving most of the cases even other people hard bricks and trivial issues that I get to see everyday and keeping myself safe from hard bricks with still not knocked out by one. all thanks to this community this is my gift that I would like to give in return, and I am just someone who likes to get to the edge of the world, exactly, on a round globe. Thank You
Android Broken into 5 parts, Worth a Look
Well not exactly broken but explained in 5 parts ( There are more but I choose not to, thank me for that)
1. Boot section(bootloaders/kernel)
This is droid's heart(accept it), responsible for the droid's birth and keeping it alive, sleeping, waking up, slowdown and speedup, overall working of the system, it has impact on every part of the droid. mess up things here, and droid won't start up at all and will stop beating and malfunction. then you will need a pacemaker and CPR(J-TAG) to revive it or it will keep the brain in coma. yes pretty much like our heart.
2. System section
This is a droid's mind, Its the place where all main work and processes are happening, with rooting and flashing you get a licence to open that mind and analyse, read logs, stats. that brain, heart and all your body is producing, you can see it all and make changes in it, put few things from outside. clean it, format it, wipe it, make amend(patches). So, imagine all that happening in your mind and the idea of cleaning your brains for once, wiping the mind, giving new and fresh experiences(newer and updated files) new interface(new UI), affecting the overall performance and changing to a whole new perspective with which you look at things.
So Clear your mind about this and remove your bad experiences and upgrade it with new stable ones. err not the custom beta and alpha ones, cause then you will give your headaches and put them in depression.
3. Data
This place is the memories part, and everything is stored up here. Everything. some would be overtly stored(on sdcard) and some deep inside you(under system/data/data). now overtly ones are not a concern here but deeper ones are hard to forget and lingers in your system, these won't go well if your heart and mind changed or aren't supposed to be the same, or in trouble will they? (i know I am good at explaining this)
4. Cache
Well, this one is the dreams part. damn I am right just admit it now. they come from your memories, keep it or forget about it, that's unto you. sometimes it can interfere with your old memories when you get new ones. so if unknown problem persist, with your heart and mind working nicely please clear your dreams and look into some of the memories. otherwise get the mind checked first.
5. Recovery
This is the soul part, whenever your heart or mind or data or dreams are feeling lost, you connect to it and revive them accordingly, or contact ODIN.
I hope you had some fun in the above part and a very clear and better understanding, So now you know where things are going wrong
The Beginning
Ensure your Charging Adapter, USB ports and your USB cable, are in good shape and working in accordance, Never depend on USB hubs or any USB port that is a faulty or slow performer, use original cables, or buy new ones, the cable does create problems in some cases. if you're sure that these are fine, then let it in charging for few hours to even a day. depending upon how fast the droid recovers.
So what do you do, when you have to go the custom way or solve your problems?
i. Press Power and Volume Up(right button) or
ii. Press Power and Volume Down(left button) or
iii.Press Power and Hold touch screen combinations.
iv. Press nicely and hold it for good few seconds there, no hurry, really.
v. Long press the power button, release the power button and, when you see a logo appear during boot-up, hold down both the volume up and volume down buttons. Continue holding the two buttons until the droid boots up with a safe mode indicator at the bottom-left corner of its screen.
vi. Plug it in PC with the USB.
vii. Remove the Battery blow air on it and pat a little and put it back inside.
So what happens after doing what I said above?
i. (a). The tab goes into download mode
ii (b). The tab goes into recovery mode
iii(c). the tab switch off/on again.
iv (d). Now the Combinations worked properly, beware cause many a times on droids this could be a seriously tricky part.
v (e). The tab goes into safe mode.
I know you got tired there holding the buttons and No you didn't had to press it so hard
vi (f). Your droid and PC responds and connects.
yeah, I know Nothing much of a Help, but it will make sense when it doesn't
vii(g).
this is an age old trick of which there is no proof of success, but it has been working since ages.
As long as you can enter download mode or recovery or safe mode you can walk the path of going custom and troubleshoot along the way. Piece of cake. Most of the ways including how to root, upgrades, lag free and better performance starts here
[if you're ready to take the plunge, remember there is no backing out.]

Choose your steps wisely here now, if possible just read the main points and see if you have done all those first. that will save your data in some case and in some save you from getting all messed up.

WITHOUT MODIFYING SYSTEM FOR HARDCORE STOCK USER
1. SAFE MODE
This mode generally helps when the problem is arising from 3rd party apps and is making your droid reboot again and again, lagging, hanging issues, so whatever is causing problem, if you can reach here, you can uninstall them clear their data and cache, and yes, free up some internal space too and backup your data from settings-backup as well. then factory reset if you want to.
2. STOCK RECOVERY WAY
You have never rooted your droid and you don't want to root and you don't want to move away from stock, well pressing the Power and Volume Down(left button) will take you there.
try to clear cache/data factory reset(will lose you data stored on internal droid) and yes it does solve few of the cases, even if it doesn't look so promising, it has solved, and will solve quiet a few issues. no chance of getting that data stored on internal., phone book, messages, chats.
3. THE DOWNLOAD MODE WAY
Flash a stock firmware Explained in post the download way.
Code:
Now if you are already Rooted or want to Root to have a better option of saving your data, or reviving your droid
it's like performing a surgery on your body by yourself.
So be careful, you have been warned, Samsung voids the warranty,
and I don't give any Guarantees that these Instructions will work for all.
MODIFYING FOR PEOPLE WHO RISK IT
1. Getting Rooted
2. Custom recovery Way and (post number 4)
3. Download mode Way. (post number 5)
AND FOR THOSE WHO WILL BLAME ME
Seriously?
The most important and most essential part here is GETTING/HAVING a NANDROID BACKUP, the very FIRST THING that you MUST HAVE DID/DONE upon getting ROOTED. Make a Stable Clone guys.
You will need to get rooted and custom recovery to do that, not to forget enabling the USB Debugging Option from Settings->about device-> Build number-> press 7 times->back->developer->Enable USB Debugging and that's the beginning my friend.

Click to expand...
Click to collapse
Getting Rooted is only advised if you're going to stay on stock rom, debloating the system and making changes yourself.
if you're going to install a custom rom, which would be generally rooted, so you can skip to getting a custom recovery first.
CF auto Root are better option for any device to get rooted rather than other options
CFauto-root GT-P3100
CF auto root for GT-P51xx
or you can visit the chainfire homepage for your device which contains the root file for almost every device.
ROOT FROM DEVICE WITHOUT PC
in cases where you can't use ODIN for rooting or you want root your droid and there is still no method explained for Root on XDA then using framaroot, towel root, baidu, kingo or any other app(they can root some sets of droid) is advised, without ODIN or in case you couldn't connect your tab to the PC with the USB, only then these apps are good ways to get root. after that you can use flashify app or other apps for same purpose that has the feature to flash .img files, you can also use Mobile Odin app which can pretty much work when you can't use Odin from Pc.
then you can download a copy of the custom recovery image.(recovery.img) browse in the app and let it do the installation for you. this is useful for droids which doesn't have that much support like we and others have here

Common Issues faced
If you have read about my explanation of android's partitions in the OP(Original Post above), you would know where exactly to look for the problems. Moving on,
For other Geeks
Please remind me if I missed few things, you see I have put up this Guide mostly of the files I have in my system partition,I might have missed few that were stored in data or cache partition
1. Tab is Stuck on Charging Screen. Tab is not turning On, battery completely depleted/Not charging, Nothing is Working
Possibilities
* if the tab doesn't feels warm even after charging for a whole day,
F1. Battery dead,
F2. Circuit/Motherboard blown,
F3. Bad Charger/charging point
F4. No electricity
if it's getting warm and still not turning on
F5. Hardware buttons not working
F6. Motherboard needs replacement.
F7. Flashed a bootloader/kernel(along with a Rom/firmware), or something not meant for your device, which is the hard brick in this category please refer to case number 5. (process on post 2)
F8. Some Custom Roms have bugs that won't Charge, stay stuck on the battery icon, unless you remove the plug and turn on. always read before flashing a Rom, if there are no info, better ask the developer before you go flashing or post your Question in related thread where they would get noticed.
2. Stuck On Samsung Logo Screen.
This could be from various reasons generally not so serious ones mostly recoverable issues of which, some are
Flashed a incompatible Custom Rom zip or any other flashable zip containing files not meant for the exact device.
Flashed a kernel/ bootloader incompatible with the Rom, wrong kernel modules, messed up system lib files, (lucky enough to still not be in hard bricked section.)
Formatted system partition and there is no OS installed. (one of the silliest mistakes I have done)
Some other that I maybe forgetting just like I completely forgot about the above
Possible Solutions
Go to the stock recovery and wipe data/factory reset (this will make your precious data that you stored vanish, except data stored on SDcard) (explained further in post 3)
Get a working stable compatible kernel/Rom or flash stock firmware. (explained in post 2 and 3)
Download from a different source cause chances are the file got corrupted or infected while downloading or transferring. (post 3)
Find the file that is stopping the device from booting up, starting from the kernel, to the system files. duh?
Go to the custom recovery way.
Go to the download way
3. Stuck in a Boot Loop.
Boot Loops are crazy and they will make you mad, they can hit you anytime for even little of tasks, Root or not root, either you are testing a new app, modifying/copying/editing/deleting/overwriting files in the system or data that don't even look so dangerous, just flashing some mod, GAPPS, or just updates rolled out by devs(nothing against them) this will surely hit you, no matter how focused and diligently you work. boot loops will make you do hula hoops.
Boot Loop is generally solved by
Hello? whatever you did that I mentioned above, just roll it back.
if you can't figure it out, well then
Remember the CORA order Quoted above in the first post? Read on
Safe Mode?
Go to recovery and clear cache then reboot.
Clear data/factory reset from stock recovery(data stored will be lost) (root users can skip this and directly go to 7)
No, Recovery?, You sure pressed the button nicely?
Flash a custom recovery image(recovery.tar) from Odin
Repeat from 1-3
Backup/Restore from Nandroid backup
Don't sit for the next exams without memorizing your lesson.
Cleared cache/dalvik cache?
Flash a Compatible Custom kernel
Find the stock replacement of the file/app you messed up from a firmware or a custom Rom, put it in a flashable zip and flash it (advance users)
Clear/data factory reset either from custom recovery. (*loses data)
Flash the Custom Rom, first dirty flash then clean flash.
Flash a Stock firmware from Odin. (loses data)
4. Stuck On Firmware Upgrade Encountered an Issue.
Well this problems hits non-root users and root users too? why? because we wanted an update.
it was trying to upgrade and something got in between to make it stop
Battery/Power/Electricity - for non root users, the most common culprit would be the battery, seriously guys, please keep the battery in mind always. it's a very common mistake that cost many of users. For ODIN users, please see you have a uninterrupted supply of power to your device and you are using latest version along with Hi speed USB ports.
kies!!! I hate that thing and majority of others will support me here. I got rid of it the day I installed that thing on my PC.
interruption from the user side while the device was taking an upgrade. removed battery? fell down on the floor? no?
hardware issue, unlikely, rare I would say, in case the device did came out with a weak emmc card.
Bad/wrong firmware downloaded files.
In case you had a custom recovery and its still working, check the custom recovery way
I Know 1st didn't helped you,
Refer to the Download Mode way and get a custom recovery
Don't forget to clear cache, you do know that's where the device keeps the downloaded/image firmware file, and that's where it is installing/extracting from. the dream partition, no wonder you got errors. you got a nightmare now
try the download mode way
probably it's best that you either forget about the mobile, or give it to a service center for a J-TAG and get it repaired.
I knew you would look here, there is indeed a last ray of hope, explained at the last thing to do in download mode way
5. Bricked.
There are 3 types of Bricks, Soft Hard and The Brick, That's it.
Soft brick
well you are safe and sound, you can even recover from custom recovery mode.
Hard brick
skynet has fallen, just like it infected the droid Arnold Schwarzenegger of the terminator version 3.0, the codes were injected into his heart making the brain dis balance and resulting in partial heart seizure and a coma, but he still had the cache and data part intact along with recovery, so it went there, restored a nandroid backup and went online again. BAM!! so easy. but why? I mean ours droid having reached version 6.0 can't recover from the same way? Where only hope here is a CPR or getting J-TAGGED? not to mention, which should be done by expert surgeons who would charge exorbitant . So, don't waste time with a jig or any other miracle to happen and please don't go on the droid with a shocking therapy. I am more of a practical guy and prefer professionalism.
The Brick
err, that's the solid one, put that on your heart, and forget about this droid and shell out money for a new one. : that's what the company wants to tell you here and that's the reason it doesn't want to put the nandroid on the stock recovery cause they want the blame on you and not them. shhh, keep it hidden, don't say I told you their secret
General Overview of the Next Options we have.
a. The Download Mode Way
Before going this way I would suggest you see the recovery mode way, if it's not working for you, then go ahead here.
You have four things that you can do (other's I never needed to venture upon)
1. Flash a Recovery -
In case you want to change or update a Recovery or fix/access a Recovery again, to root, complete backup from recovery(nandroid), install new custom Rom, install stock Rom, plenty of options here. Probably the safest option here cause you don't lose your data unless you do something wrong here as to format it. whether you root your tablet or not, install a custom Rom or stay on stock, everyone MUST have a custom recovery, I don't understand why Stock recovery can't have this option as well?
2. Flash a stock firmware package -
in case you are on stock recovery never rooted,
can't reach or can't flash anything using custom recovery,
bootloops(applied in all cases), want to revert back to stock factory state. tab system is behaving weirdly, virus and Trojans attacked or you just want to upgrade or change your droid firmware.
Note Using this method, will result in the loss of all your data stored on the device internal card.
3. Flashing a Bootloader
Generally these are included in every stock firmware pack. if you had a ICS(4.0.4) stock Rom, and the device got an Official JB(4.2.2) update. you must update to that firmware first before flashing any later custom Roms[from kk to M(6.0)], the version which never got released officially. flashing this part separately is very risky and done with utmost care, remember it's your droid heart. don't fool around with it.
3. Flash firmware with pit file -
Warning : this is some high level flashing, it will re partition your device along with the stock firmware. in cases where NOTHING ELSE on the whole Internet worked for you, and you have tried almost everything, only then choose this path with clear mind. make mistake in this, and your tab will virtually turn into a paperweight. if you're not sure you could handle it, please send it for the service centers. this is going to flash every part of the droid's body
4. Flash the 4 files with pit
This is the secret way, where miracles can happen even when there was no hope of recovering yourself.
b. The Recovery Mode Way
Stock recovery - Here You can clear cache, there is nothing much happening in clearing cache, just clearing some temporary files and making you feel like you have got some space cleared out. it's just files that you most probably already used.
data/factory reset and reboot. Easy and simple solution . that does solve some of the problems you face without modifying your device much. so those of you who are afraid to flashing things and ending up on some bigger mistake, you can give this a try, but keep in mind, you will lose all your data stored in the device.
there is apply update from recovery, but that seldom has use in an average android user's life nothing much of a recovery.
Go to download mode way of flashing a custom recovery
or
If you have rooted your tab somehow using framaroot, towel root, baidu or any other app, without ODIN in case you can't connect your tab to the PC with the USB, then you can use flashify app or Kernel Adiutor(the latest one) or any other apps that has the feature to flash img from inside the device OS. you can download a copy of the custom recovery image.(recovery.img) browse in the app and let it do the installation for you.
Custom recovery - Here you have many things that you can do depending upon which recovery and which version you choose. CWM is past, philz is ok, TWRP is awesome. most of the options are common in these 3, but some are really better and fast than the previous ones. we will discuss only one, my favorite TWRP(Respect for the legend CWM though), the process is common on all but twrp is more feature rich.

Setting Up Everything
Before proceeding Always keep device battery fully charged and NEVER go flashing on low battery. Very Risky. Don't forget.
Always check the files that you are going to flash on your device. generally files will have device model mentioned in their filename.
Be Sure that you don't lose electricity or laptop on low battery while working. the device takes time to update.

Things you need to Set up a 'Flashing Environment'
No, I am not going to talk about a flashy party setup
i. PC running Windows 7 and 8 (with 10 I haven't flashed anything yet, but it works.)
ii. A working data cable(some cables are bad and will not detect your device if you see unknown device better get a new one)
iii. Samsung USB Drivers it's much better than having samsung kies on your pc. I would personally suggest from my experience along with many people who have suffered from samsung kies, it's not worth the hassle. ODIN and KIES don't work alongside, so you will have to close.
iv. ODIN 3.10 (download plus instructions as well I used 1.85, 3.07, 3.09 All worked, and so will 3.10. if not, try different ones from Odin 1-85 to 3.07. these links have more step by step and detailed covering what I have left.
v. 7Zip better download this cause it can unpack most of the files.
Press and hold Power and Volume Up(right) button on your device for few good minutes until you see a download mode screen
Connect your USB cable to PC and press Up to Continue. sometimes there could be problem with the USB ports, you should check in all the ports available. avoid USB hubs or the front panel USB in case of PC, don't let a faulty port ruin this for you.
Problem/Failed with Odin? Refer to this thread Good Points here as well.

DOWNLOADING AND READING FILES
Believe it, this a very big problem that people tend to overlook
The file you need will look something like these
"P5100XXDMD1_P5100OJVDME1_P5100XXDLL2_EUR.tar.7z"

P5100 - Generally the first 5 letters/numbers means a device model number.
XXDMD1 this is PDA which will be 5 letters(much older devices)-6 letters denoting firmware build version.
OJVDME1 is CSC version these just contains regional wise APN, nothing much.
XXDLL2 is Modem version.
EUR is Country Code.
.7z means you need 7zip to extract this file.
Now see these 2 examples here
"S7562XXALJ4_S7562OXXALJ3_S7562XXLJ3_HUN.tar" and "S7562CZNUAMI2_S7562CCHUAMI2_CHU zip"
Sure it's S7562 device but wait the other one is S7562C !!! totally different device firmware. make mistake here and you are sure going to lose.
I Hope you can make out the difference now for every device now.
Now the real file that you need will always be inside a zip/tar/7z the correct format is "P5100XXDMD1_P5100OJVDME1_P5100XXDLL2.tar.md5 "
Remember to extract it and get the md5 file.

*Bump Download firmwares available smart-gsm.net
Download firmwares available easy-firmware.comThe Only reason I am putting this here is while I was searching for genuine websites, I had a very hard time finding through sites that looks nothing else than scams and fakes and rarely had files that I needed and password protected. this websites has ads, but looks organized and for tab series, it had at-least all the firmwares downloading.
PHP:
Yes so, it will take time and require a good internet speed, there are other sites, but I don't recommend them unless they are from good source or sometimes the only option. Options are also available from GSMhosting site as well, its another good community but I feel XDA is much better. still if you have no options. you have to get it somehow. just stay away from the survey sites and bogus ones. specially the blogspot ones.
Recovery Mode Way
Recovering from a custom recovery
Important PartCreating Nandroid Backup - This is the most important thing that you will ever need, and will always regret not having it when you chose this path, should be the first priority.
Getting Inside
Switch off the device
Let it completely shutdown
Hold Power and Volume Down(left button)
This is how it looks saw that backup button? yes that is where you tap first (other recoveries will have different looks, but same "backup" and
This is where you do it . by tapping again or navigating through the volume up and down button in case of older recoveries this would not at all be same, this is the most latest feature rich recovery.
Those Running CWM older builds, won't find the options to select boot, system cache and data and instead there will be just "backup" and backup to external.
CWM by default will Backup boot, system, data, cache partitions. Philz will also do it. But TWRP has better features. although they do the same. You just select system, boot, data and cache. that would be all to recover using nandroid backup.
Now here it depends on what you are trying to do and what would you like to recover from, also depends on what you are comfortable with doing and how much space you can spare. if you have a lot, I would say skip this step and backup all for once.

Not Noob Friendly
if you have that same custom Rom zip that you would like to restore the backup of, then there is no need to copy/backup /system partition again, it will save you some space. so you can skip it in that case for TWRP.
if you're only going to modify device kernel - backup boot. or just data if you already have the custom Rom with kernel.
other than that twrp offers what CWM lacked, skip md5 generation during backup well this is a good option and saves some time while backup, on restoring you can also enable or disable it. the purpose of this is simple, md5 is like a security/seal on your backup file, so you don't mess up anything while restoring it on your device. after all you never know when a virus might attack or you might put the wrong files on it. if you are sure about your talents, you can skip it or else it's better to let it generate and verify while restore. CWM has this setup as default.
Now you have one? GREAT! GENIUS!! Now whenever you encounter a problem make sure you can use it like a BOSS.
Restore Nandroid Backup
Enter recovery mode by Pressing Power and Volume Down(left button),
you reach the main screen,
you see a "restore" option and tap it,
you will see folders name starting with the date you made a nandroid backup,
you recognize which one you want by the date and information listed there, and select it. CWM only offered dates, but twrp even offers more detailed info including OS version and Rom name. one more reason I suggest you to use twrp.
In case you want only data to be restored, then you choose advanced restore and check the data and restore. but before doing this part make sure you are not restoring conflicting data or system or kernel with incompatible versions.
you can't restore a data backup from a Jellybean Rom and put it on a custom Rom based on Lollipop, neither a kernel from Lollipop to jellybean.
Data should only be recovered on the same Rom you took the backup from.
In case the custom Rom developer rolls an update of the same fixing issues,(not some major changes) then you can in some cases think of getting this worked out smoothly. This is called a "dirty flash". which is the reason why sometimes users experience problems running certain Roms, even when they are good and stable Roms. So before complaining to devs make sure you follow the clean install method.
Note: System and data most of the times will cause problems. Kernels are not meant at all to play with. they are the biggest source of bricks.

Wiping Part - Steer Clear the problems away
this is where wipe takes place[PIC]
here are the wipes options on a custom recovery
Factory reset - Wipes cache, dalvik, data/ excluding your media part on the internal drive.(your pics, videos are safe)
this will generally clear you problems if they are not some big issues. but you will lose the apps and contacts messages stored.
Advanced wipe - Format system
you can try to do this first if you don't want to lose your data while troubleshooting.
format system if you're facing issues with the files on system partition, but remember to install the same Rom you had earlier. if you had stock, you will need a stock Rom zip not to forget keeping the file ready beforehand on the external SD card.
Beware while navigating in advance wipe menu, never wipe in a hurry, never drink and wipe, never take eyes off here, cause you might end up touching external SD card, USB-OTG, internal storage and lose your precious data
Format data - this wipes the data partition
problems arising from the data partition side could be solved here, but you lose your precious data on the internal and get rid of the bad, virus, trojans, trouble making apps.
How to perform A CLEAN INSTALL when you are going to update to a new Rom?

Format System, without Deleting Data partition. before doing this, please do a nandroid backup in case you mess things up. if not, format system again and flash the Rom that was initially running with that data.

Now Comes the Installing part
Installing Menu
You download a copy of a custom Rom or stock Rom, after following the developer's thread, reading through it's bugs and reviews. you don't want a unstable or alpha Roms.
There would be installing process explained on that thread follow it and always make sure that inside the zip file it contains a meta-inf and system folder with boot.img) always look inside before going to flash, don't trust me, don't trust anyone. although
if you tried to flash a firmware zip file containing a .img file, without Meta-Inf folder, it won't flash. cause the custom recovery needs instructions from updater-script. Now, I know this was mostly going on like this before, but now with latest custom recoveries, (twrp) you can even flash .img files without needing a zip.
You perform a Clean Install wipe stated in the wipe section above
Reboot to Recovery(Don't select reboot to system, there is no system after clean wipe)
You browse through the files list and external storage,
Find that zip file and
Swipe or press or touch to flash it.
You wait for it to complete the process then
You can wipe/cache/dalvik and reboot or you just reboot. depends on what you choose "clean install" or "dirty install".
You want to report any errors while flashing? you are free to do so on the Rom thread, don't expect me to solve those cases.
If all went well, reboot to system and your tab should be up running again. if not refer to the Download mode Way.
The Download Mode Way
The Download Mode Way
1. FLASH A CUSTOM RECOVERY
Find the recoveries in their respective threads. For P51xx and P31xx Recovery thread others can look in their respective device sections, XDA has development thread of most of the Samsung devices and people do post there.
it should look like this on your address bar
"http forum.xda-developers.com / galaxy-tab-2 / general"
xda website /__ (devicename)/ (sub-forum)
(development) OR (/general) section
You can always google it too.
remember you will need a recovery.md5 that will be inside a zip file extract from it.
Always check whats in the archive then go the recovery mode way, it should be .md5
Sorry I have not put up detailed step by step process here because my guide is covering a lot of things already and this is something each device specific, refer to this For General step by step instructions with pictures, this has very detailed process.

2 FLASH A STOCK FIRMWARE
These package contains files needed to update or revert to the same position where it was shipped to your country along with your android device. you can find all Samsung device firmwares released from all parts of the world, and yes, you can flash firmwares of other country/regions from the sammobile site just stay away from the carrier specific firmwares(unless you are on one) that should be used for the same specific carriers device only they are married to the carrier company and probably won't let you have your own ways with others.
You should also remember not to downgrade a stock firmware once you have upgraded, that will surely create problems

3. FLASH A BOOTLOADER
First ask yourself why you would want to do this?
Be extra careful with this part, if you have already flashed a updated firmware, you don't need this part.
Those who are using old stock firmware, please flash a stock last updated firmware. you won't need to do this.
Those who did not follow the above two, so it's now unto you, this a risky thing, you have been advised you are going further yourself
Those who are experiencing problems that are not solved even after most of my other instructions here, then it's onto you to decide you want to try this too or not. this could solve problems when device is in serious condition, after all it's the heart partition and remember no downgrades in this once you upgrade. thats it. this could seriously create problems, including bringing back the emmc issue as well.
Refer to this DETAILS AND INSTRUCTIONS to FLASH A BOOTLOADER for SAMSUNG TAB 2 SERIES follow safely by @Joery360 other users please be careful with these files and don't go on flashing others files? okay. Great!

4. FLASH FIRMWARE WITH PIT FILE
Wait!! You are sure that you want to try this part? this is the point of no return. Whatever happens to your device by following this guide, good or bad, it's your own responsibility. You can't blame me for it. so be sensible, if you're not sure please let this be done by someone who has the experience of dealing with this kind of stuff.
Now pit files are some serious files, they contain information about your device partition and they help flash erase and rewrite files on their correct partition, so better not take a wrong file, sometimes you have the same device but different internal space, so don't end up choosing a pit file for a 8 GB variant on your 16 GB variant of device, in that case your device will end up using 8gb only, or worse if it's other device, it might never boot up again.
Always remember don't flash pit files ever without a firmware file in place.

if it shows failed while flashing, you did used correct files, right? after this if there is still a download mode running on your device. try the special case files.
this has happened with me on a unknown MTK device, the pit file was slightly different from the original one on device, so it failed, but that was at the start before it could flash. I did somehow managed to flash that different pit file, just lost some disk space. cause I used a lower variant pit but it got the device running up again.
The device takes a long time to boot while it's updating firmware, so you are required to have sufficiently charged battery, Take no chances here.
if even after a successful flash with Odin, you face problems, then that's a emmc bug case. motherboard replacement or emmc replacement, or tab replacement. nothing else.
5. FLASH PIT WITH 4 FILES FIRMWARE
Find the repair firmware files at this Website
it has the 4 files for most of the devices including the Tab 2 series
Instructions for using these 4 files, however please note that the only difference would be the ODIN versions, cause device needs specific ODIN version, some can flash all.
this is the only way, that I have seen working for numerous devices and it is most successful one among all options to recover an almost bricked device, on which you have tried everything.
For other devices

Hello guys,
I'm a complete novice on rooting or flashing cellphones, I'm just a regular user of a Moto X Play XT1563 (bought in Colombia / South America) that wants to upgrade to Nougat 7.1.2.
I want the 7.1.2 just for a regular usage: apps, internet, bluetooth, NFC, camera, GPS, phone calling and of course a good battery performance.
I want to kindly ask for your guidance in all steps required for the backup and upgrade, so if you can please guide me about the whole process I will appreciate it a lot.
Thanks

Hello!
In short, the process for our phone would be...
0. Backup data.
1. Unlock bootloader. This will void your warranty. Unlocking bootloader allows you to use fastboot mode to flash custom images to your phone from a computer.
2. Flash TWRP Recovery. This is done in fastboot mode. Once you have TWRP, you can flash on to or modify the system partition (and other partitions) of your phone on the go.
3. Format the /system partition to get rid of the existing ROM (stock in your case) and then flash whatever ROM you want. This is done using TWRP.
4. There's no fourth step.
Its pretty straightforward, detailed guides to each of the steps are available in this forum. You should use the Index Thread pinned on the General forum to get the links to the required guides at one place. Use the search if you encounter trouble. Then there's the forum to ask.

Thanks for your response,
I bought my cellphone two years ago so It already went out of warranty so no issues with that step, I already found the guide to "Unlock bootloader" but before I start with it I would like to ask if after that the phone will be unuseful? I mean, after unlocking the bootloader can I start the phone and continue using it? It's my only cell phone so I want to be aware if I will stay long time uncommunicated.
My second question is about the new ROM I will flash, I've no idea about what "versions" exists or where I can download them... so is there some kind of "most stable" version using Nougat 7.1.2? or some "ROM Reliable supplier"?
Thanks

Unlocking bootloader will wipe all your data (it will trigger Factory Reset on your phone). Other than that, your phone will be 100% usable.
Roms are available in Android Development and Original Android Development sections of this forum. Just check the threads that include [ROM] in their title. You have to decide for yourself which rom suits you the best - read its description and what users say in comments.

As said, after unlocking bootloader the device will be wiped- You will have to reenter your Google account and reinstall applications etc. Not a big deal.
Custom ROMs sometimes take a few iterations until some bugs here and there are ironed out. Sometimes it happens, in others one may end up switching to a complete fresh ROM. In such instances, you will usually have to make a "clean install" (i.e. a factory reset) and then reenter the Google account and reinstall everything again... It sounds irritating, but nowadays it's pretty much straight forward, and if you don't have hundreds of apps it usually is finalized in 10-15 minutes and is semi automatic.
Updating to a newer version of the same ROM sometimes can be "dirty flashed" (i.e. without wiping all your data) so in a couple of minutes you are set up and ready to go. More convenient, but if something isn't working right and you complain in the thread, certain chances are you will be politely asked to make a clean install first amd some users may flame or grill you alive for dirty flashing and complaining at that :laugh:
Most custom ROMs are usually based on either AOSP or Lineage OS (aka LOS) with some custom modifications. The first post in a ROM thread usually mentions all the rich features (or lack of), how to install (pretty much the same: make a backup in twrp, wipe data/system/cache/dalvik, flash ROM zip file, flash Google gapps zip, flash some additional optional zips such as supersu/magisk/whatever for root etc). Then some download links, faq etc.
It's good practice to read the first post (aka OP), then at least the last page to get a feel of the ROM (e.g. see what others are praising or complaining about this or that), then search for specific stuff that may concern you. For example, some ROMs had this cellular data bug that it got disconnected and required restart. You may decide this os crucial for you and choose another ROM, others may use the device for other things and couldn care less about cellular data bug...
Enjoy, it always feels good tp flash a new ROM, a new version . F!ck LeMoto for delaying the update for so long- You may have been waiting for update to Nougat as early as last year's November or October. Well, on custom ROMs it's here for many months!
On the other hand, they usually say stock ROM is more stable, and in many cases it is also true...
Now you know more or les what you're dealing with: free choice vs. waiting forever.

Thanks for your thoughts,
After reading here and there I finally was able to flash AOSP Extendend v4.4 on my cellphone, it seems to be working fine.
As I said I was not looking something specific I was just annoyed of waiting so long for the official update (it seems it will never happen) and wants to be in touch with Android Nougat, maybe now I will use my piggy bank to save for a Pixel phone
Thanks guys for your guidance

Hi,
How it is working? Did you found any bugs? eg. problem with battery, with mobile data, lte, camera?
