Whenever i install a custom rom my sgs2 bootloops, it runs fine on the ones i flash with odin, but when i try to flash a custom rom it bootloops the i9100 screen and i can't even get into recovery, only download mode...
Name a ROM that's not flashing for you and list your install procedure.
Which other ROMs have you tried to install? What recovery do you currently have?
latest clockworkmod recovery...i reboot into it i wipe data and dalvick, then i install the rom and reboot(i am not a newbie) i have tried with cyanogenmod 7 and 9 , and some custom roms here in the forums...MIUI also...

CM7 (and CM7 based ROMs) has to be flashed twice from recovery, and often won't flash from a CF Root kernel; instructions in the Nightly thread, post 1.
I had no issue flashing CM9 but I came to it from CM7 so I had CWMR 5.0.2.7 already. I'm unsure if people flashing from a CF Root kernel have issue moving to CM9 directly or not.
i am on latest recovery i told you and i tried with other roms 2

What's your latest recovery? I have 5.5....
Did you flash twice from recovery like I asked? Did you flash from a cf root kernel?
Since you're not giving useful info I'll unsubscribe from this thread now.
Miui = cm7 based

sorry, i am on cwm recovery 5.0.2.7
And did you flash cm7 TWICE from recovery? It won't install otherwise.
Sent from a Phone
yes i flashed it twice, also when i chose the zip it finishes installing in like 2-3 seconds, from what i know a rom takes about 30 seconds to install at least, and then it bootloopes from the samsung galaxy s i9100 screen with the yellow triangle and it keeps restarting and i can't even get into recovery after that, i have to flash cf-root kernel again in recovery then i install simple and clean 2.4(only rom that works besides stock) and i do it all again:|...also when i try to install cm7 with rom manager, when it reboots to install the rom it boots into the stoock recovery and gives me an error, does the battery level count?
Downgrade CWM to an older version.
Flash cfroot KK5 or something like that via Odin and see if that makes a difference.
Also intratech has the old bootloader in his thread to flash via Odin. Might help also.

ok thank you i will report back
Have same problem after flashing KP8 rom... I believe it installed new bootloaders and it won't flash the older ones again.
Went through about 5 or 6 stock roms, some booted but had problems with google and the phone apks . Reloaded kp8 and it works perfectly... Don't have time to play around, working.... Something to do later...
CyanogenMod7
To start off a clean slate :
1. Flash XWKK5 ( Frankenstein build ) from intratech's thread via Odin
2. Flash CF-Root for XWKK5
3. Boot into CWM
4. Wipe data
5. Wipe cache
6. Advanced -> Wipe dalvik cache
7. Install zip from sdcard -> CyanogenModxxx.zip (xxx=version)
8. AGAIN Install zip from sdcard -> CyanogenModxxx.zip
9. Reboot phone
10. If your still getting a bootloop but your keys are backlit , turn off phone , remove and reinsert battery, turn it on
CyanogenMod9
You need to flash the new bootloader too ( read instructions on the CM9 thread)
MIUI
Same as CM7 , except you don't need to flash it twice
Hope i helped
EDIT : Going back from CM9 -> You CANT flash CM7 , you have to flash stock first then CM7 , also you need the old bootloader

How is your data and/or internet connection? Have you checked the md5 sums of any of the cm7 DL's?
data and internet are fine on other roms, the downloads are good i have downloaded from official site several times
So why do you see a need to have three seperate threads on the one topic
Sent from my ThinkPad Tablet using XDA App
If u have searched u must have find the answer.
Whenever you are flashing any Samsung custom rom and stuck on boot screen, just flash any CFROOT kernel via odin it will boot.
and for CM7 & MIUI just flash Siyah 2.1 or Speedmod 13...it should boot.
This problem was faced by me and I did found the above solutions.
@MODERATORS kindly delete the duplicate posts....

Not true, Mine goes into boot loop constantly... If it does boot then I get error about google and phone apks and can't get past the "touch the android" page....
I believe their is a minority of sgsII's tha have this problem, might be something to do with the new bootloaders not being completely wiped but it doesn't matter how many times I install a stock rom I get problems... And yes, I always flash the cfroot kernels after... Doesn't help....
Hi.
Having come from the HTC HD2,I am a complete noob when it comes to galaxy s2 and flashing Roms etc;
I know I had problems.....until I discovered that unlike the HD2,placing a rom on the sd card means placing it into the internal memory of the phone and not the sd card you have inserted.
Hope this helps!

What I meant was:
SD card = internal memory of phone i.e. 16Gb
External SD card = the micro SD card you physically insert into the phone
hi guys, first post
ive had my rooted galaxy s2 with the latest siyah kernel 3.3.2, i had cwm recover 5 and rom manager
i tried to flash cyanogen mod through rom manager, following the steps it gave me, i downloaded the files through rom manager and went through all the prompts till i clicked agee to go into recovery mode.
once it did that the phone shut off but would not turn on again so i went to turn on manually, it loads the samsung galaxy screen with the yellow triangle but goes straight into a white flashing screen.
Ive tried taking the battery out, leaving it and putting it back in again, still a flashing screen,
check what i9100 you have and download correct cm9.
using cwm format data system cacha sdcard dalvik
flash cm9 using cwm
rommanager doesnt work on GS2

ahh rats i should have known rom manager does not work, , im just stuck in a white flash screen on boot up, cant get to cwm, although i can get into odin
would reflashing my kernel on odin get me through? everything is back up onto my sd card.
Try flashing a kernel first, and if that doesn't work, flash a rom in Odin, re-root your phone & restore your backup. But yeah, don't use Rom Manager with a kernel that has CWRecovery. One or the other. Rom Manager has a habit of doing stuff like what's happened to you on SGS2's which also have CWRecovery installed.

awesome, I tried flashing the latest siyah kernel, the one that i already had on my phone before the problems, that didn't do anything to get me through, any suggestions on which kernel/rom to flash?
because you are on siyah and im not comfortable with that, please flash a stock kernel or cfroot kernel and format system data partitions after that.
now flash any official stock ICS or GB rom using Odin.

ohh sweet baby jesus im i flashed a cf kernel and now im into cwm on 4.0.1.5, can i just normal reboot my phone now?
No need to format anything. Given you want to use CM9, I'd recommend you flash CM9 Resurrection Edition in Odin, put the latest CM9 nightly & Gapps on your internal/external SD card then flash that nightly & Gapps in CWM (read the first page of the CM9 discussion thread thoroughly & follow the instructions to the letter. From there you can stick with the CM9 stock kernel or flash whatever other kernel you want to use (provided it's CM9 compatible).
From then on, if you want to flash CM9 nightlies, do it via CWM/CWRecovery, just don't use Rom Manager this time I use CM9 as well & I have it frozen because I use Siyah (which has CWM).

alrighty! thanks for the info, is cf kernel compatible with cm9? i want to just have one kernel that'll handle most roms, any suggestions?
ive reloaded my old stable phone version, the version i saved before trying to flash cyanogen mod with rom manager, this version has siyah and stock rom, back to square one *phew*
i still say wipe first, cm9 will come with its own latest cwm that can be used to flash any custom roms after.
flashing via odin version is easy and fool proof as it has everything bundled for correct working of cm9.
If you flash CM9 the CM9 kernel will overwrite/replace your CFRoot kernel, which is fine. As I said in my previous post you can stick with that if you're happy with it, or you can flash any other kernel that's CM9 compatible.
No suggestions/recommendations. Because your experience will not be the same as someone else's using a given rom or kernel. If you want to go down that path, try some kernels to find one you like. To see if a kernel is compatible with CM9, read the the dev thread devoted to the kernel in question.
OK. Given you're back @ square one, Atifsh is right when he says flashing the Resurrection version (Odin version) then flashing Gapps/nightly from there is probably a good way to go for you. Once you've done that, you'll be able to flash CM9 nightlies via CWRecovery. As said previously, read that first page of the CM9 discussion thread/instructions thoroughly before you do anything.

Something similar happened to me too. I flashed stock XWLPG, then siyah 3.3.2 and did a factory reset. After that, got stuck in a flashing white screen after the yellow triangle.
What I did: boot on download mode, flash XWLPG over PC Odin once more, did a full wipe BEFORE flashing siyah and then siyah. Everything went ok this time, but eventually I found out that every time I do a factory reset after siyah that problem would occur.

Since you are running stock ICS 4.0.4, which had super brick bug on its kernel, You must flash a custom kernel e.g Siyah Or speedmod, If you are going to flash custom Roms and stuffs like that.
You can visit here, much easier, forum.xda-developers.com/showthread.php?t=1501719.
After rooting, flash a custom kernel immediately

Umm, if I'm understanding correctly, you installed the ROM- CM10, that is- and/or kernel via Odin. CM10 and the Mercurius kernel are zip files (.tar, .pit and the like are for Odin, not zips...if I understood correctly).
You want to place the ROM and the GAPPS zips on your actual SD card. Make sure the SD card is working properly. Reset and go to CWM (Power+Vol up).
Then, accd to the instructions on the CM10 page:
"Installation:
Reboot to CWM
Make a Nandroid (optional, but recommended)
Format /system if you had a different GApps package installed
Install ROM
Install GAPPS if you just formatted /system
Wipe data/factory reset if you are coming from Gingerbread
Reboot
??? (wait a while...)
Profit"
I'd say make a backup before doing any of this, but I'm assuming you're beyond that point....But before going on to CM10, it might be a good idea to recover your device first and back it up. Maybe flash a GB rom via CWM or Odin before proceeding to CM10, making a backup just in case...
Ok

would he have to flash the kernel first, though? I'm unfamiliar with rjs, but am assuming that rjs version of CWM would be identical to entropys version of CWM, which means that he could just flash the CM10 ROM since it has the kernel baked in.
When I upgraded from Chip -> CM10, I just flashed via CWM, upgrading both the ROM and CWM in the process.

Hi everyone, I have a serious problem about my GSII.
so first of all, when CyanogenMod 12.1 Nightlies come, I am excited to flash it.
but after i download it and flash it. it seems ok. on recovery (CWM Kikat compatible) while it installs, it says
Detected filesystem ext4 for /dev/block/mmcblk0p9 which is /system right?
and
Detected filesystem ext4 for /dev/block/mmcblk0p10 which is /data right?
then it shows
Script succeeded (0.200000)
after that i wipe the data and cache and the dalvik and reboot
after rebooting. its ok, no problem at all.
now i go back to recovery (cyanogenmod recovery, so it changes) and flash PA GApps Mini Package, (yes i have it one i did'nt delete the last PA GApps)
so... after flashing i forget if there is an error or something. but after i reboot. it stuck on Samsung Galaxy SII logo. (NOT A BOOTLOOP)
after that i decided to revert it to stock rom but it did'nt work. i don't know whats happening but i think because of the PIT Mod. i use the PIT Mod to install Bigger GApps on unofficial cyanogenmod 12 by Lysergic Acid. so i think this is the problem is the Modified PIT file.
Can someone help me to Fix my problem? Im very thankful for the one who helps me.
