Hey everyone,
First of all, i apologize if any of what i'm asking here is stuff that has been covered before. I have been searching myself for answers for the last several days and have found plenty of good info, but i am new to android and i think i need to ask some question to help get a base level understanding of what i need to do. I am a bit nervous about bricking my phone so i maybe haven't been as adventurous trying to get everything running as god intended.
Firstly, i have used and understand Odin, using it to flash roms and such. I have rooted the phone and installed ROM Manager and clockworkmod 4.0.1.5 on the phone, but when i boot into recovery mode, it is still on the android recovery 3e and i cannot do the update.zip, I get signature verification failed. Now i KNOW this is cause of the android recovery 3e, and i have found this issue has been encountered plenty before, but my confusion is in some of the solutions i have found. Mainly the terminology and how the steps directly apply to the phone. For example, I found on another forum thread :
1- Copy the Zimage from your rooted kernel and paste it to SD card of your phone.
2- Flash the Stock kernel via Odin to get rid of Yellow triangle.
3- Flash the Zip file (Zimage) via CWM which you've already pasted in Step 1.
i don't really understand what the zimage is. Why do i need it, what IS it frankly? Where do i get it or a stock kernel for my phone. Does versioning matter much? i read that for the most part the kernels are almost identical to each other, and the fact all i really need is for the android recovery mode to be 2e or whatever it is (so it will not do the signature check on the update.zip file), that i don't really need to pay much attention to the actual kernel version.
What i really need i guess is for someone to break it down for me and either explain the steps or give me a detailed step by step on how to get clockworkmod recovery working so i can proceed with the cyanogen mod running on phone (not enjoying touchwiz at all).
Again, sorry if i am giving anyone spasms at my noobish-ness, but i have been searching for my answers for a day or two now and i haven't been able to find anything that really tells me what i need to know.
Phone : GT-I9100M
Android : 2.3.3
Kernal : 2.6.35.7-I9100XWKDD-CL
Build : GINGERBREAD.UGKG2
Thanks

That means you have not installed it flash CWM and \Root from here .
Root + CWM .
http://forum.xda-developers.com/showthread.php?t=1103399
Beware of following instructions from a separate rom to the one you are flashing .
1- Copy the Zimage from your rooted kernel and paste it to SD card of your phone.
2- Flash the Stock kernel via Odin to get rid of Yellow triangle.
3- Flash the Zip file (Zimage) via CWM which you've already pasted in Step 1.
i don't really understand what the zimage is.
ZImage is the kernel .
Why do i need it, what IS it frankly? Where do i get it or a stock kernel for my phone. Does versioning matter much? i read that for the most part the kernels are almost identical to each other, and the fact all i really need is for the android recovery mode to be 2e or whatever it is (so it will not do the signature check on the update.zip file), that i don't really need to pay much attention to the actual kernel version.
You are confusing yourself .
Flash correct CWM from above link .
Choose the custom rom and follow the instructions posted for that rom .
CyanogenMod as the man says
Warning : Not for new users, flash this build only if you know what you are doing !!!
#Followed by his install instructions ~~~

Thanks for the reply. I have been doing more reading and i think i am understanding the rooting process a bit better.
I looked at the link you posted (thanks for that, i saw the forum post for the i9000 but i never could find the i9100 post for some reason) and i DO have another question after reading through a good chunk of the posts on it.
There is no CF Root for my kernel, but the reply that was made to someone else with my kernel version was :
"Flash the Stock 2.3.4 ROM (XXKG5, XXKG6 or XXKG7) and root with CF-Root-XXKG6."
I understand that process and how it works but i thought you were only supposed to flash roms based on your firmware version? My KDD kernel version is running on 2.3.3
Will this cause any issues if i flash the stock 2.3.4 ROM?
Download cm7 zip for the newest nightly.
Copy it to internal sd card.
Flash any cf root kernel
Boot into recovery
Wipe data and cache, you will lose all your data on your phone, so backup sms (I recommend sms backup +), also you will lose App data so you might want to back that up first using something like titanium backup.
Wipe dalvik cache (under advanced)
Chose install zip from sd card
Select the cm7 zip
Reboot
If you get stuck at the boot screen go back into recovery and flash the zip again

Thanks Veyka.
I think i'm ok with the CM7 install process. I am probably going to wait until i really feel like i understand the whole process from front to back before i start messing with that though.
I can't get to that point yet however since i haven't been able to get CWM recovery working yet. I have the Android Recovery 3e, which will not install from zip files that aren't digitally signed.
So i'm trying to get CF Root installed and working, however, as mentioned in my previous post there is no CF Root for my kernel. I would like it clarified if it is ok for me to flash to a 2.3.4 stock ROM (i'm running 2.3.3) and then use a CF root for a the new ROM.
I was under the impression that this was not a good idea.
If i should not be doing this, is there a recommended way to upgrade my firmware to 2.3.4 so i can use a newer CF Root?
Thanks
Pick a new stock rom, I would go for kg6, flash it via odin.
Then flash the kg6 CF root kernel via odin and you will have cwm recovery.
Don't put the pit into odin and don't tick repartition or update bootloader.
There is a good thread with all the info you need on flashing stock roms with odin and a list of all avaliable roms.

Thanks for all the help. I was able to make sense of the process (which is actually quite simple, just needed to put it all together in my head to make sense) and get everything done.
Appreciate all the help!

Hi,
I have rooted my phone using the quick root guide found here and therefore I have my stock kernel back w/ root. Do I need to install a cf root kernel?
Also, when the new ROM gets flashed how does one recover the apps and data lost?

Use Titanium Backup PRO for your app. You can backup all of them then restore on any rom.
Is there anything that Titanium Backup doesn't back up for which I need to use another application?
Thanks.

Hi there,
I am new to xda and new to Android hacking.
What I wanna ask is, (I guess it's of most newbies concern as well), can we have a 100% backup of our system (stock ROM)? Obviously, it is important because:
If we perform an official (OTA) update to a new Android version. And we don't like it. It is possible to get back to the old original one which we are used to. (not everybody likes new things, and/or not every new thing is good)
If our phones are having some problems. And we have to give it back to the company for a fix. In most cases they will flash a new ROM for us. If we wanna keep using the old one (explained in #1), we have to keep a copy of it by ourselves.
If we want to try new custom ROMs, we may want to switch it back after trying.
Whenever we do any modifications, it's always better to keep a backup/roll-back point. In case anything goes wrong, we have a safeguard.
For the official warranty issue.
Yup I do see there are some official stock ROMs downloads for some particular phones. But those are not really a backup of our original ROMs. And it's always hard to verify if those downloads are the original official releases. And, if those downloads are 100% stock ROMs, this means some guys out there could make it, so what is the way to do so?
Or, how those mobile phone companies do it in their labs?
I have been doing researches on this topic for a few days. Some posts claim that their methods are "backup stock ROM" or "backup before rooting". But after digging into it, they requires rooting and/or flashing CWM. Here comes a few questions:
Questions
Rooting will in fact changes some files/data of the system. So backup after root is NOT getting the original stock ROM. Is it?
Is there a method to "un-root", so ALL the changes are TOTALLY reverted?
Installing/flashing things like CWM in phone requires rooting, which would make the ROM not original. Is there a way to extract the system backup from a computer externally?
In addition, I have found some related pieces. which could be useful to anyone viewing this post, and might be useful for you to solve this (my) question. :fingers-crossed:

ht tp://www .modaco .com/topic/351269-backup-original-rom/
In reply #5, user C3C0 raised a method of backing up the original stock ROM without root. But it seems he is flashing CWM and that method is only for ZTE Skate.
adb backup tool of Android SDK
At the first sight i came across this approach, I thought it is the official method to do whole system (ROM) backup (WOW - how nice!). But after studying for a few more posts, I think adb backup can only backup app+app_data, and possibly some system settings only. Am I correct? And also, adb backup is only for ICS (Android 4.0), isn't it?
adb backup usage: ht tp://forum.xda-developers .com/showthread.php?t=1420351
(But mentioned in the bottom of #1 the poster is having some issues on using adb backup. Perhaps there are some bugs and not reliable(?)
One more question on adb backup: Can it backup just one app+app_data, and restore just one app+app_data, without affecting other things? If yes, we don't need to root and don't need Titanium Backup (which requires root) for backup app+app_data. Isn't it?

If you flash CWM, you will retain your stock rom unless you try to flash custom rom or updating kernel from CWM recovery or from ROM Manager. if you are using samsung android device, you can check your rom in odin mode

I'm in the same issue here, looking for a way to backup/extract the stock rom of the HW-T18, cat B10 model, for the purpose of flashing it to other B10's since several of the cat b10's we bought here is without danish and a few has the danish system language.
so i want to take the rom from the b10 with danish and flash to the ones without.
if there is a better way of adding a system language to the phone please let me know (apk maybe ? or flashing an update.zip containing the danish lang) but do remember i'm not a dev i just have ORD.

That's not correct, not every phone has a clockworkmod built for it, my phone is a alcatel authority, and not only is there no clockworkmod, but the newest update.zip, unroots it, and sorceforge only has the the stock update. In any case the manufacturer has put the wrong id's into their usb drivers for it. You can't even use the clockworkmod builder, for it. The only phones that get support, are the more popular models.
does the bootloader need to be unlocked for this to work

How to start phone in bootloader mode and where to type that command?
I have spent the day to figure out how to root an S3 with 4.3.
I´m no stranger to flashing but I get confused with all the threads and all the links, stickies and "how to´s" all over the forum.
Can someone please link me to the proper stuff I need?
* I know I have to downgrade via ODIN to be able to gain root and thereby get a custom recovery. But to WHAT version do I need to downgrade to? 4.1.2? 4.2.2?
* Is there an absolute STOCK deodexed 4.3 prerooted firmware that can be flashed after gaining root and custom recovery.
Just to make myself clear... the searchfunction has not been working today, so I have been making my searches via google... and that can be a bummer when looking for some handson instructions.
Can anyone be a gent and provide me with some links?
Best regards
Just flash a custom recovery with odin (I'd suggest philz) then the rooted 4.3 stock rom, you don't need root to do this. Chose the stock rom from several in the general forum.
Really? That easy? Great news!
Just a question... I have to flash the custom recovery and the flash the rooted 4.3 ROM before first boot? I have to enter custom recovery directly and flash the new ROM? Or can I boot the phone with just flashing the custom recovery, and then take my time finding a good ROM while running the stock 4.3...

You may find that a stock rom will restore stock recovery on first boot, so you may need to flash your new rom straight away.
You could also root your existing rom just by flashing CF autoroot.

Hello. I have galaxy S2, and I wanted to install CWM. I installed it (CWM-KitKatCompatible-i9100) with odin with auto reboot unchecked and after that it doesn't boot up. It can go to odin and CWM modes, but the android doesn't launch. I did a recovery to phone storage, but still I cant launch the phone... Can anyone help me?
Flash a compatible kernel to your installed rom via recovery. Or you can flash an insecure kernel via Odin.
Simple cwm flashing won't boot up your phone.

Well, there are 3 kernels which are quite popular here which have their depth range till kitkat roms.. A simple search on xda for them will lead you to the respective threads.
1. Gustavo's
2. Dorimanx
3. Apolo
If you want a KK rom then download a KK compatible kernel mentioned in the op for those threads, put that on external sdcard and boot to recovery. There you can flash the Kernel file. As you don't have a rom on your phone it would be better if you download a rom and gapps package too and flash them. After flashing a kernel, reboot to recovery and then flash rom and gapps.
If it's difficult for you to put those files on sdcard, you can flash a stock rom via Odin, flash a kernel e.g. philz, apolo,hirox via Odin. Search for these keywords here on xda. Once you have a working kernel and rom, you can download a custom rom and gapps, put it on your phone and follow the procedure which I mentioned first.
If my steps are still confusing to you then you require to search for these terminologies here on xda,read and understand them carefully and then proceed.
You didn't mention what OS/Firmware was on your phone before you started.....this is VERY important to know as it will decide what you can / cannot flash.....
Custom kernels are OS version dependent.....some will only work with ICS, others will only work with JB.....some are exclusively for KK.
You need to check this.....

well I couldn't check cause it couldn't boot up, unless there's another way... But whatever I managed to write 4.4.2 Kitkat on my S2 and there's alot missing feature's like, I cant organise my program menu, I cant add many widgets that I had used in my previous android, there are no notes, phone file explorer and other what is irritating... Maybe there's some another pack that I missed when installing or what?
Hi, I'm going to buy a Pocophone, and it's my first phone. I actually rather like MIUI, but I will very probably try to flash a pixel experience-like ROM when those come out. However, I have no idea how to revert to "factory MIUI" should I want to.
I know, pretty noob question, but if you could point me to a tutorial so that I have an idea of what to do, that would be cool!

Yes but I don't want a theme. If I flash another ROM, and I lose, let's say, the infrared recognition capacities because it's not part of standard Android. Well, then I'll want to re-flash the original MIUI. Are there any tutorials for that?
To be able to flash a custom ROM, you need to:
1. Unlock Bootloader
2. Install Custom Recovery (TWRP)
3. Flash Custom ROM along with GApps
To revert back:
1. Get a flashable MIUI zip file for the device.
2. Flash it using stock/custom recovery
3. Relock bootloader maybe
Now at the moment you don't really need to worry much about these things. Get the phone, play with it and when you decide to flash a custom ROM, better take a nandroid backup of MIUI. It will save you from searching for MIUI later if you decide to revert back

Make sure to check BOOT, SYSTEM, DATA, EFS (if available, depends upon the recovery) when taking backup
