What roms will not update the bootloader - AT&T Samsung Galaxy S II SGH-I777

I have played around with the unnamed rom and I was wondering what other roms can I try out that will leave me the option of using creepy's return to stock method?
Sent from my SAMSUNG-SGH-I777 using XDA App

You can get that information from each rom thread, or ask in the thread before flashing. But if you accidentally flash a bootloader that won't allow you to boot with a jig, or accidentally flash an I9100 bootloader, you can always flash back to the I777 UCKH7 secondary bootloader. I've recently added instructions in the return to stock guide.

Thanks creepy. Just don't want to do anything irreversible.

None of the ROMs in the i777 Dev forums have Bootloaders, that I am aware of. Bootloaders can fairly easily be identified by the naming sbl.bin . If you see that in a ROM i recommend staying away from it anyhow. Should be no need for a ROM to include a bootloader.

To my knowledge, the only ROMs that include bootloaders are straight leaks - if it's an Odin One-Click download beware.
There are, to my knowledge, no CWM-flashable ROMs that include bootloaders for the I777 at this moment. I cannot guarantee this when Hellraising I9100 ROMs - some of them might include BLs.

The only way you can flash bootloaders is through Odin correct? I haven't heard of cwm flashable bootloaders in any Samsung-android phone thread.

we had cwm flashable bootloaders on the Captivate. its perfectly do-able on this phone too.

You can also flash ANY of the leaked versions with Mobile Odin and it will not flash the bootloaders by design.. If you use the paid version you can also flash them and retain root. I have used it to flash the leaks solely for the purpose of pulling out the modem.bin files from them.
But as others said I do not know of any of the time in the Dev section that includes different bootloaders. I think the leaks are ONLY in the General section.

I installed Lite'ning v6.1 rom (in development thread Mods/Roms Library sticky)
My phone now says Model Number: GT-I9100 (I have I777) !! Did I flash a bootloader or I9000 firmware? (I only installed the ROM.zip (w/e name, I usually rename them so I just know Lite'ning_Rom)

Where does your phone say I9100? You need to provide more specific information. In the initial boot screen, in the flash counter, in settings\about phone, or where?

For a screen shot, touch power and home softkey at the same time.
That rom is a ported I9100 rom. The phone gets that info from the build.prop file, found at /system/build.prop, and his build.prop didn't get changed for the port to I777. You can edit the file with a root file manager or with adb, and the edits will appear in your about phone. You just have to make sure that you only edit the items that relate to the info that needs to be changed. You could maybe compare with a build.prop from the I777.

are we able to hellraise the vk Rom located here? http://forum.xda-developers.com/showthread.php?t=1377069

Best ROM for battery life?

Hi,
Just wondering what is the best ROM available at the moment either 2.3.4 or 2.3.5 for best battery life?
Thanks!
i was using [ROM][2.3.4][XXKH3] Cognition S2 v1.5.1 with great battey life,
now trying some 2.3.5 based roms but too early to tell for now
I'm experiencing great battery life with stock KI3 Rom. Anyway, i flashed it yesterday so it's too early to tell, but that would be my suggestion.

The link you provided is for the XXKI3 Kernel, not ROM. THe link for the full ROM can be fund here http://forum.xda-developers.com/showthread.php?t=1277020.
I'm no expert, but I understand that you have to be root user and have clockwork recovery properly installed and funtioning to flash any ROM. Anyway, once that is done, it's really easy to flash new ROMs, just reboot in recovery ROM, and install from zip file in SD card. If this is your first ROM I strongly suggest you prepare yourself and read the articles there are about it, how to do a full backup in case anything goes wrong, etc...
Also, if it is your first time flashing a new ROM, you must understand that you may have to try various ROMs before you find the one you like, but that is the fun of it.
I've tried all the roms in the original dev section, and to be honest most are similar, depends on kernel as well. Most importantly usage, what might give one user excellent battery life might give another poor battery life. Best way is testing yourself.
I like VillainRom for its stock like features with the ability for us to tweak instead of a fully tweaked rom.

You can flash the Kernel with Odin but you may encounter problems depending on the ROM your are on. I'm not an expert in the subject of flashing diferent kernels so I mostly prefer not to do it. Instead, I keep the kernels that come with the ROMs I flash since the dev that created the ROM and chose to use that kernel knows a lot more than I do.

Plus one. Using Cognition, trying to scout and see which 2.3.5 ROM's are decent!
I have now rooted my phone and installed GT-19100_XXK13_original.zip
I am unsure if it's overwritten the kernal I flashed yesterday which was the Frankenstein one
How can I tell?
Just go to setting, about phone and look for the kernel version (you have to scroll down a bit). If it says XXKI3 somewhere it means you have succesfully flashed the kernel.

thats a good remark.
to get a proper measurement of a roms battery performance should be either with "video loop" while screen being on all the time or with the screen being off all the time... (best with both battery times)

[Q] Need help making sure i choose the correct CF-Root kernel

Hi
(I have done a fair search about this and did come across some results but im still not quite sure on what to do)
This is my first attempt at rooting my phone and i want to make sure i dont end up with a $600 brick.
Im going to use the CF-root method outlined in this tutorial thread: http://forum.xda-developers.com/showthread.php?t=1103399
My phone is a Samsung Galaxy S2 I9100 unbranded and bought in australia.
I have already searched for my kernal versions on http://hotfile.com/list/1967350/4304d29 but its not listed.
My kernal is: [email protected] #2
This is the one listed in the CF-root tutorial thread and the one im planning on using: CF-Root-SGS2_XW_XEN_KK2-v5.0-CWM5.zip, would this be the correct one?
Here is a screenshot of my "about phone" page:

}
That is my main question.
If im successfully in rooting my phone am i correct that i can go ahead and start trying out different ROM's? As long as that kernel is installed i can just install whatever ROM(for the SGS2 of coarse) i like on top?
Big thanks for any help.

Yes, having a CF-Root kernel means you get root, busybox and CWM recovery. These tools allow you to install custom roms and mod your phone with ease.
You may find that most roms come with another kernel, as long as it isn't a stock kernel things should be fine in terms of modding
Sent from my GT-I9100 using XDA
Your choice of kernel is correct.
After rooting, you'll be able to flash other roms using cwm. you'll find plenty of tutorials and videos floating arnd on the net.

Cheers for the help guys, much appreciated.
So just how important is having the correct kernel? In terms of safety, ah la non bricking my phone is it best to have a kernel as close to the most up to date official stock one?
And when i do flash a custom ROM/Kernel do they already come with root or ?
Big thanks for any help.
There's always a (very small) risk you'll brick your phone with any given flash. If you used the wrong CFRoot kernel, the worst that could normally happen is the phone wouldn't boot. As long as you chose the CFRoot kernel that is an exact or closest match to your current kernel, you'll be fine.
The only thing you need to be careful about re: possibly bricking your phone is ensuring you're flashing firmware for the SGS2 variant you have; I.E only flash I9100 firmware to your phone.
Every kernel that I've seen that's been supplied with a custom rom has been rooted. Obviously if you flash a new kernel or a rom (I've never seen a rom without a kernel supplied), the new kernel will overwrite your existing kernel.

It's always reccomended to have a kernel as close to your most up to date official stock one, but in terms of safety, if things were to go wrong, ie: bootloop/stuck on boot logo, then this is classed as a "softbrick" & not a hardbrick, & is relatively easy to recover from by just pulling your battery then going into recovery & doing wipe data/factory reset and wipe cache! & if that fails then there's always this: http://forum.xda-developers.com/showthread.php?p=15330252 or this: http://forum.xda-developers.com/showthread.php?t=1457458 for your salvation!
In general, as long as you're not flashing a Pit file or a Bootloader through Odin 3, then the chances of you hardbricking your expensive toy are minimal!
Once rooted, you can always use CWM recovery, or install mobile odin (needs root!) to flash whatever you like from there! At least that way you'll never have a warning triangle or flash counter going up in value, & you can always use triangle away here: http://forum.xda-developers.com/showthread.php?t=1494114 to reset your counter for warranty repairs!
Awesome help guys thanks very much.
I have one last thing to clear up and then ill stop pestering you guys, i promice
So if i manage to get the initial CFRoot kernel flashed and root my S2, then can i go ahead and flash a custom kernel/ROM like this one(following the instructions given on the page to a T)((for example)([ROM][ICS][02/05][IMPORTANT P.1454]HyDrOG3N-ICS 02.05[BYEDROG3NICS.ED'][DASWAGG])(http://forum.xda-developers.com/showthread.php?t=1530179) ive found in the "Galaxy S II Android Development" section and only have the (very small) risk of bricking?
I know this is all in the tutorial thread but i just wanna make sure im doing things correctly.
And damn, mobile odin is sweet, once i get my head around things ill def be using it.
Big thanks again for any and all help.
Thats what the instructions say flash via CWM recovery .
Risk of bricking if you follow the instructions is almost nil .
jje
I have another thing i need to clarify,
So most modded rom's come with their own kernels, can i choose to install just the rom and use the CF-root kernel? Would that be on the safer side of things? And if i did use the included kernel that would be for performance increase side of things?
Thanks for any help.
Install the ROM, then flash a kernel cleaning script and finally CF-Root. A cleaning script is optional but usually a good idea when switching kernels.
The included kernel in a ROM is usually just there by preference of the ROM dev. It doesn't always mean it will be more stable or better for performance/battery etc. The only way to find out is to test - in the end it's whatever works really.
Cheers for the help

[Q] [Q's] SGSII I777 Help!

Hi Everyone!
This is my first thread on XDA.Hope I'll get quick and helpful replies
I just bought a samsung galaxy s2 at&t variant.
1 - The phone is rooted and superuser is intalled but when I go into recovery its something like android 3e recovery which is stock recovery I guess,so my question is will I be able to flash using this stock recovery if not should I re-root my s2 to get clockworkmodrecovery or is there any other method to get cwmr?If I have to re-root my s2 then whats the easiest way to do it?
2 - How to flash custom rom without risk of getting bricked?
3 - How to make backup of stock ROM and other things?
4 - Another question is my phone is unlocked now and will I loose it after flashing?Suppose my phone is locked again so will I get my phone unlocked again through galaxsim or similar softwares without any hazard and use any sim I want?I read somewhere that its important to use the same software for unlocking again that u used before,is this true?
5 - My phone is running on 2.3.4 and I want to upgrade to either ICS or JB.Are there stable JB and ICS roms available for s2 i777?
Is there any official update of android for I777?
Some more info:
Baseband Version:I777UCKH7
Kernel Version:2.6.35.7
Build Number:GINGERBREAD.UCKH7
I am still learning so plz ignore my noobism.
Thanks.

I'll give you a quick head-up then you go off and do your own.
In the bold, since it's rooted, get the Odin Mobile, flash the custom kernel which should already included the CwMR. From there, boot into CwMR and flash any custom ROM you want.
The open sentence, you said the phone is rooted, then you asked how to root, I think you need to understand more. Anyway, read those Stickies threads more and more. For the starter, search for "creepyncrawly" and read ALL threads in his signature.

Do cwm and rooting have any relation?
The phone is rooted but when I go into recovery its other than cwm and through which I can't install custom rom so I asked if I have to "re-root" to get cwm or not...
Things are little clear to me after reading stickies.
Ignore the first two questions and answer the others plz.

Root and CWM have no relation. Having root will allow you to obtain CWM by flashing a kernel that includes CWM. All of the kernels for our phone on this site include CWM. So as votinh mentioned, install mobile odin (which you can find on this site), and then flash one of the kernels from this forum, which will give you CWM.

If you get and get to know with 1 and 2 then question 3 will be easily answered.
Get into the recovery, play and understand all options, it's not many though.
About 4, I said 80% you will not lose the unlock if you understand the factors. It means 20% is your fault if you do not follow the instruction so go off and hunting that 20%. Be sure of what you do.
About 5, do you know what version of OS currently on your phone? Get it right first before doing anything else.

Ok so before flashing custom kernel and rom after that,should I backup stock ones ?
"Nandroid" will this app help me in making backup of stock rom and kernel and also to recover whenever I want?I am just asking bcz I had bad experience with it when I made backup of stock rom on my galaxy mini.I was confused between root and cwm bcz when I rooted my mini cwm was included with it without flashing custom kernel.
Which kernel to flash,any specific?

Sure.
Use the UCLL6 plus root package from the link. The one-click downloader is easiest. Then, if you want, install Mobile Odin lite or Mobile Odin pro and use it to flash a custom kernel such as AJK or Siyah.
And... I would suggest you read through the first link in my signature to learn the basics.

Not really sure, but probably not. AFAIK, most of the lost unlocks happen with Jelly Bean. But if it does happen, you should be able to unlock it again with galaxsim unlock.

Depends on what you want. UCLL6 is Ice Cream Sandwich, 4.0.4. If you prefer Jelly Bean, there are several great firmware distributions, both Samsung based and AOSP based, available in the development section of this forum.
In one-click downloader update,what will I have to do?Just to open some app or any other thing?

1. Enter recovery and perform a wipe data/factory reset.
2. Open one-click downloader on your pc's desktop.
3. Put your phone into download mode.
4. When the phone is recognized in the one-click downloader, press start.
If you need detailed descriptions of these steps, read the guides linked in my signature.
After the phone restarts with UCLL6 stock plus root, I would suggest you use Mobile Odin to install a custom kernel as I mentioned before. The phone will run better, and you avoid the possibility of the eMMC cap erase bug, if that still exists in the stock UCLL6 kernel (which is unknown).
If you want custom firmware instead of stock, you are now ready to use ClockworkMod Recovery to flash that new firmware.

Not really sure, but probably not. AFAIK, most of the lost unlocks happen with Jelly Bean. But if it does happen, you should be able to unlock it again with galaxsim unlock.

Not trying to be mean here, but every single question you asked has already been answered and is freely available here on xda to read. Read every sticky note (those are important threads) and search for any issues you have questions about, either using google or xda searche. I realize its easier for you just to ask. But a lot of time and effort was made to make the threads that already exist to help new members and allow our forums to remain unclogged with many threads pertaining to the same questions. I do wish you all the best, and it can be overwhelming. But we've all got to be held to the same standard .

Bump...help me with the imei prob...
Your friend most likely corrupted his efs while trying. Did he back up the original efs?
He should try this tool to see if that fixes it.

[SOLVED][Q] After all... Got a brickable phone?

Hi, I recently bought an S2 from AT&T and I upgraded it from 2.3.4 to 4.1.2, when I install the famous eMMC Brick bug checker it says YES, insane chip.

Then I saw this so strange, so let's try another app.
With the Chainfire app "Got Brickbug ?" I had the same result.
But this is too strange to a noob like me, because I heard the bug is from 2.3.4 to 4.0.4. OK, so, is my phone going to brick if I wipe something?
Thanks in advance.

Why risk it? Just flash a known, good kernel.

Is Jeboo a good kernel for 4.1.2? When you flash you have root too?

I'm not 100% sure, but I think Jeboo is made specifically for ShoStock3.

To gain Root, just use Framaroot apk found here... http://forum.xda-developers.com/showpost.php?p=37508806&postcount=1
I recommend that u select the tab "Install SuperSU" and then select the "Aragorn" exploit. Works flawlessly for me on i777 Stock JB 4.1.2 everytime.
And as for a kernel for i777 JB 4.1.2, i suggest AJK v4.8 "NoSwap", as of this post that is the latest version. U must use the NoSwap because of the Stock i777 u r on. Here is the thread... http://forum.xda-developers.com/showpost.php?p=36993409&postcount=1

I installed AJK 4.9 NoSwap but still the "Yes, insane chip" message. I don't know if this is true. Please tell me. I don't know what to do.
Thanks in advance.
Sent from my SGH-I777 using xda app-developers app
AJK doesn't have the brick bug, so your app is giving you wrong information. I've used AJK for ages, performed multiple factory resets from recovery and have never had any problems.
My advice is to stop relying on third party apps to tell you whether or not a custom kernel is safe. The op in ANY kernel thread generally gives you all the information you'll need, plus you can check in their respective threads to see if any user is reporting issues.

Several different Samsung phones received kernels with the cap erase bug present. Some were bricked by it, and some weren't. In an effort to understand why, it was learned that some phones (of the same model) had a susceptibility to the bug, and others didn't. The "Yes, insane chip" message simply means that your phone is susceptible to the bug. However, if you don't have a kernel with the cap erase bug present, then no harm will come to your phone.
My phone has a chip that is susceptible, but of course, I have never had anything but a known safe kernel on it. All you need to know is that as long as you use a safe kernel, you have no worries. Remember that this problem occurred quite a long time ago, and Samsung has eventually understood the problem and prevented it from re-occurring, although they have never acknowledged it publicly. Anything Jelly Bean would be safe, even stock. And anything custom would be safe, because the developer would make sure the cap erase bug was not present.
Thank you the both! I will try if there's no problem with the kernel.
Thanks.

Tried to flash TWRP on rooted Galaxy S4 (SCH-i545PP) - now I can't boot into recovery

Hi-
I tried to flash TWRP earlier today and now when I try to boot into recovery, the screen just goes black. The phone is a rooted Verizon prepaid Galaxy S4 with stock ROM.
Fortunately, the phone will otherwise boot normally. How can I reinstall a recovery system?
Thank you!

Odin stock from www.sammobile.com. Stock recovery is included in the tar. Use FlashFire for flashing, the bootloader is locked on this device.

Thank you. Do I download from the Firmware section of that site?
Also, after I flash that, will I be able to change to a custom ROM, like Cyanogen? I have been experiencing a lot of overheating and poor battery life.

OK, I just flashed the stock firmware that I downloaded from Sammobile.com using Flashfire. My phone appears unchanged. I still cannot boot into recovery mode, and all of my apps and settings are unchanged. What did I do wrong?
Thanks again.

no and no ?
you can't run any custom roms on this device other then stock tw based ones
Despite numerous attempts, I still don't have access to recovery mode. I used Odin to flash the stock firmware using the .tar file. I just tried flashing the PIT file, but the button quickly turns blue and says RESET, and my phone boots regularly.
Any ideas?

So there are AOSP ROMs posted here for no reason? That's BS.

I thought that's what I did - I downloaded a stock firmware from Sammobile.com - I545VRUGOF1_I545VZWGOF1_I545VRUGOF1_HOME.tar.md5
I tried to flash it again last night and although it passed, nothing on my phone was different (apps were all there, did not go through new phone startup sequence).

do I really need to explain what locked bootloaders are ?
the i545/i545pp is locked the only exception is if you have a original one thats still running 4.2.2 and no you can't downgrade
the s4 is a dead device MOVE ON

Yes I know what a locked bootloader is, but I am rooted with a custom ROM. You can flash ROMs and mods with FlashFire. Not dead by any means.

How are your comments helping anyone? You think it's dead, good for you. I, for one, am still currently using and developing for this device. As long as people are still using the device and the ROMs that are available then the device is not dead.

because he was asking if cyanogen was a thing ITS NOT
stop arguing with me
there are no custom kernels no custom pre-boot recovery you may or may not get root depending on your firmware version
there hasn't been a update of Note to any of the Roms in this sub in YEARS
sorry you disagree you are welcome to waste hours trying to get kexec running on the device then we will have something untill then its fuctionally dead because nothing you flash is gonna make a s4 relevant in 2017

So your advice to someone looking to make their device run better is to buy a new/different device? Just because it isn't "relevant" to you doesn't mean people aren't still using it. Kindly take your comments to a relevant forum.

I just bought a brand new S4 in Feb 2018 - on purpose, installed SmartDroid so I can enjoy a lightening fast quality device that's ad-free and has 3 - 4 day battery use - Trust me when I say, this is absolutely the most relevant aspect of the Smartphone experience.
