[Q] Constant Boot Loops when trying to install new ROMs

I have CWM 4.00.15 installed and I tried to install Ryyu's Rom (Wipe) by putting it on the SD card and rebooting into recovery, then selecting the zip file and hitting apply. When the installation tried to update my kernel, it just froze and rebooted. I was then stuck on a boot loop between the Galaxy S screen and the CyanogenMod boot screen. I know that Ryyu's did not install correctly because the CyanogenMod boot screen was still there. I had to use 3 button recovery and erase cache, davlik cache and user data before trying to install AOSP Essence, but same problem happened. Installation dies and phone keeps rebooting in loops. Finally, gave up and went back to CyanogenMod Nightly and it worked.
Why can't I seem to install any other ROMs besides Cyanogen? I know I am doing something wrong, but not sure what. Any advice/help appreciated. Thanks.

Have you tried starting from a clean install?
Try starting with a stock rom and then to activate Cwm flash a modded Kernel.

Hi,
this is what I initially did to get Cyanogen on:
1. Used Superoneclick root to root phone
2. Check that 3 button recovery and download mode works. Recovery version was 3e, so installed superlagfix from android market. This automatically installed ClockworkMod Recovery as well.
3. Use CWM and flashed recovery for Samsung Galaxy S i9000
4. Reboot into recovery and select the CyanogenMod zip file and click apply to install.
To install subsequent ROMs, I just put the zip file on my SD card, reboot into recovery and repeat step 4 above, after clearing cache and user data. It is after that I get stuck on boot loops.
I did do a Nandroid backup before my initial Cyanogen install so I can go back and restore it, but it would be Froyo.

when coming from CM / MIUI - Samsung based ROM
you MUST flash a 3 file firmware with pit and re-partition.
Cyanogen and MIUI use different partitions than samsung ROMs so this is why you are having issues.

Ok, just managed to flash Darky's EE 10.2 using Odin. Not sure if Odin is the ideal way, but it worked. Really enjoying Darky's. Thanks folks!

[Problem] [Solved] Help cant access recovery while on ICS

Update: Solved
Thank you for everyone's reply and help.
What worked for me:
Downloaded Mobile ODIN v3.10
Downloaded Goku v1.5-10 TAR (Kernel-Goku-V1.5-10.tar)
Flashed firmware with Mobile Odin with MD5 signature check
Can now boot into recovery
Currently on:
CM9 Version 9-20120515-Nightly-n7000
Build date Tue May 15 23:06:26
Kernel version 3.0.30-CM-q6804ca8
I cant seem to get into recovery while using any of the ICS roms. I've tried several CM9 bulds, Kindgroid, Stunner and a few others. I doesn't matter if i try to access it through the hardware keys (press and hold the Volume UP+Home+Power) or through one of the software options (reboot into recovery). After the samsung logo apears the screen will turn black. I'll have to restart the phone with the power key.
Everything else seems to be fine. I can get into download mode just fine. I have no problems downgrading to a gingerbread rom from pc odin or mobile odin. Also theirs no problem for me getting into recovery from any of the gingerbread roms I've tried.
I first noticed this while I was on ICS stunner. It was the build with the affected kernel. Everything was running smooth for me. Recovery and everything else seemed to be working fine but when i started reading posts about the brick scare i became afraid of doing anything else on that kernel.
I followed Entropy512's advise:
If you are running an affected kernel:
STOP USING IT IMMEDIATELY. FLASH A SAFE KERNEL USING ODIN/HEIMDALL.
DO NOT wipe in recovery
DO NOT flash anything else in recovery
In general, DO NOT use recovery at all
I flashed his DAFUQ releas using mobile odin while still on stunner. Everything seemed to go smooth. After flashing I checked under setting -> about phone -> kernal version and his kernel was properly displayed. I tried going into recovery but the screen would turn black after the samsung logo.
I've must of done something wrong while flashing Entropy512's kernel because ever since I flashed his kernel I havent been able to get into recovery while running an ICS rom.
TL;DR
Cant access recovery from ICS roms but recovery works fine while on gingerbread roms

Did you try before flashing ics do a 3 wipes first while in girgerbread for a clean installation?

Yeah it was one of the 1st things I tried when I encountered the problem.
Can anyone confirm if the recovery is stored in the same place for both ics and gingerbread? I feel like I might have damaged some sectors and might have some bad blocks. Everything else seems fine though.

How about 4 wipes including format/system and also use jbroid even though your not installing a kernel but rom still use it.

Flash stock GB rom. Reroot it and then check everything is working fine? If yes then flash ICS rom.

Thanks for everyone's reply
I've tried jbroid and formatted system but it didnt help. Like I said... everything is fine on GB, recovery and everything else. I've been back and forth several times already. Everything seems to be working fine on ICS too. I just can't access recovery no matter what I do while on ICS. I'll try wiping 4 times from gingerbread this time.

In the system setting of the phone there is back up and reset and there you can format usb storage, this will format your internal sd, this is in ics setting i forgot about gingerbread. You can do this while in gingerbread to be safe, format your internal sd.

Yes.. I've tried that before installing my current ICS rom. Actually I formatted both the internal and external SD while still on GB. I'm still wondering if the recovery stored in the same partition space in both GB and ICS. I can't understand why I can access CWM recovery on GB but not while I'm on ICS.

i too have the same problem even though i can access cwm manually cant install any zip file but if i use abyssnote kernell everything works fine the problem started when switched over to ics from gb

Wiping more than once is pointless... I don't know where people get silly ideas like "wipe 3 times".
When you switched to something else, did you flash it using CWM or Odin?
Try flashing a different kernel using Odin. I have seen that in rare cases on some devices, doing something like the following:
Flash one kernel from a recovery
Reboot directly to recovery using CWM's Advanced menu
At this point, the device will be stuck either always booting to recovery or never booting to recovery
Flashing a kernel with Odin/Heimdall - NOT "Mobile Odin" (I hate that name because it's completely different from Odin) or CWM often breaks these loops.

problem accessing recovery
hi today i solved my problem of not unable to find cwm in programs and flashing zip files from recovery while on ics. first i flashed abyssnote kernell then rebooted into recovery did all the three wipes and in addition formatted data, system and cache. then used jbroid kernell cleaner. installed fusion rom flashed green theme rebooted at last could see cwm in programs can flash any zip file now

Thank you sir for your swift action.

How did you flash abyssnote kernel without being able to enter recovery?

[Q] Stuck at boot screen after wiping

I installed CM 10 stable and Semaphore Kernel. Worked great. Then went to install gapps and got lots of FC's so I went on to clean cache, dalvik and to do a factory reset and suddenly I got stuck at semaphore/boot logo and couldn't go into recovery. Got the recovery fix and installed it via Odin, and it works. But, it doesn't allow me to install anything from external SD card, only internal. Of course, I don't have anything there.
What should I do? Any links for tar versions of CWM and CM 10 for i9000?

Hmmm, is it safe to assume everything will be OK if I just flash any stock firmware from sammobile?

Yup, that combined with this did the trick.

Galaxy S bootloop

I wanted to flash custom rom on my galaxy S. I flashed clean rom, then kernel with CWM, but there is a problem. Everytime I try to flash rom it ends with bootloop. I tried cm7, cm10, rootbox, miui 2.4. Every time is the same. It starts installing (only few secodns), then screen becames brighter, then restart and bootloop. I tried different kernels, roms but still same result.
ps. sorry for my english

Hi, here is a great guide to fix bootloops:
http://forum.xda-developers.com/showthread.php?t=1660596
Usually, doing factory reset, wipe cache and wipe dalvik cache before and after intalling the ROM should fix the issue though.

I'm doing all necessary wipes, I can recover from bootloop easly but I want flash custom rom and I can't. Istalling zip lasts few second, not few minutes, there is a problem.

Sorry if this is too basic, but are you using the right ROM for your phone?

of course...

I don't know if I'll be able to help you, but can you please list the exact model of your phone just in case? You can see the different variants here:
http://en.wikipedia.org/wiki/Samsung_Galaxy_S#Variants

It is just GT-I9000. Now I managed to flash CM7.2 but if I want install CM9 or CM10 im getting bootloop and can't enter recovery mode ;o

Sorry, I can't really give you an answer with that information. If you are following the steps in each ROMs thread, you should have no problems patching as far as I know (someone more knowledgeable than me may say otherwise).
Maybe posting the exact steps you are following would help me or others to find out what the issue is.

I'm following right steps. It's not my first phone. I know how it should be but it isn't. Here are my steps:
Flash stock ROM w/ODIN v1.85 - OK
Flash CF-Root w/ODIN v1.85
Wipe Data/Wipe Cache
Phone now rooted OK
Boot to CWM Recovery
Install zip from sdcard
Select update on SDCard (cm-7.1.0 from CM site)
Flash completes in just a few seconds
Phone reboots automatically
Now stuck in boot loop
Remove battery
Go to CWM again and reflash CM7.1 zip
Now i have CM7
Reboot to recovery, facotry reset, wipe cache, wipe dalvik
Flash CM9/CM10, finishes in few sec, reboots, then black screen, can't go to recovery mode ;(((
Flashing stock with odin again...and every time is the same, sometimes when I choose CM10 i see info: "Incompatible Partition Layout" so it may be the reason (something with partition, idk)

My phone has never rebooted like that, so I'm not sure what the problem is. I do know I use ODIN v3.07. I also have CWM 6.0.2.7
Best of luck finding a solution, sorry I could no be of more help.

I think CWM6 would help but I can't find this version for cm7

IGNORE ALL LINKS BELOW, they are for the wrong phone
I don't think it matters what CM you have on your phone, you should be able to upgrade CWM from recovery: Maybe not in i9000...
http://forum.xda-developers.com/showthread.php?t=1843825
Doesn't work in i9000 as far as I can tell: You can also try installing TWRP, which I like better than CWM and have in a different device:
http://forum.xda-developers.com/showthread.php?t=1694617
Finally, and don't take me on this because is just a guess, maybe your bootloader is not working properly? I don't really remember how to do this myself:

You are showing me links to CMW and TWRP for i9001, I have i9000...

You are right, please ignore those links... I do know I patched CWM 6.0.2.7 through ODIN on my phone, so maybe that's the only way. In any case, I'll let you look for the actual links.

i9305 stuck on rom booting screen after flash

Was flashing my friends i9305 and now it wont boot any rom I flash... always gets stuck on the first boot screen until I take out battery.
I flashed CWM 6.0.4.7 using odin.
I have tried flashing several roms (CM 11, CM 10.1, PACman 4.3)... Each one will flash with no errors, then when I reboot after correct GAPPS it just gets stuck on the loading screen forever and won't boot up into ROM.
Wipe data/cache, wipe dalvik, wipe system > Install rom from zip, install GAPPS from zip > reboot (even here I wipe system/data/cache - still doesnt work).
Any ideas on why it won't load up the roms....

Well I figured it out... since it was never flashed or anything before (from stock rom)... I just went into the Mounts and Storage menu, and formated /cache /system /data manually and it finally worked.
Hope that helps
