Hello guys!
As the title says, I keep on having boot loops after flashing any custom JB Roms (Jedi, LiquidSmooth, CM Nightly, Slimbean). I'm not new to flashing roms (I got LG units though, SU660 and KU5900). When I tried flashing ICS Roms, I don't have any problem. But I want JB that bad!
I followed KonstantinKeller's thread of restoring/recovering from a bad flash (going back to GB), rooted following Melvin's thread. Then did all the prerequisites..like the common wiping of data, clear cache & davlik. But then again after flashing JB roms listed above, I keep on having boot loops!
What did I do wrong? This ain't my first time flashing (first time on this phone -T989- though)
I read some posts with almost the same problem, but I don't think I found a solution for this. Any good soul that can extend their help is highly appreciated. Thank you in advance.
I got a bootloop before when trying to flash JB roms and what I did was restore to original state (using the bad flash recovery technique), and then not rooting it but installing cwm through Odin and dirty flashing the Rom in cwm. Once it flashed I used it for a few to make sure that everything was working correctly. Then I got the goo manager app and got twrp. After that I followed all the steps in the OP (Jedi jelly) and flashed the Rom. Now I'm running Jedi jelly 3.1 perfectly. Hope this method helps.

are you using darkside scripts to wipe? because they will cause bootloops

is there any way to reverse the loop that the darkside wipe is causing?
it REALLY sounds like the recovery u are using is TOO OLD. Make sure u are using the latest version of twrp (2.3.3) to flash all jellybean roms.
TWRP is backwards compatible and touch capable, so if you're worried about flashing GB or ICS ROMs it'll do the trick just fine
it is however a requirement for flashing all 4.1 ROMs.
Basic install instructions:
make sure u have root
download goo manager from play
open > menu > install open script recovery
agree to everything, but make sure t989 is in the downloaded image name
reboot to recovery u should see twrp

Ive got this message in cwm when was restoring (jj's hybrid for locked bootloader): no app2sd partition found, any ideas?
Locked Bootloader Arc S.
When i want to format sd-ext --> same message.
Prince
Bump
Prince
That means that CWM didn't find a second partition in your SD card used by Link2SD.
Is it working fine, JJ ROM?
Im just wondering if i can flash it with this 'error'.
Prince
I presume jj's rom has app2ext built in, but it shouldn't affect the rom. But check on the rom thread.
sinksterĀ©
I was asking, but no1 replied.
Prince
It will work. That "error" is just a check if a sd partition exists to make use of. Wont affect sysyem if missing.

hints that migh be helpful to prevent trouble when flashing custom roms & kernels
hi there,
i'm not entirely sure if this will help you but generally speaking i came made a few observations about the fact that some people, mostly repeatingly the same users, encounter problems with their custom roms and/or flashing them, while others don't, albeit they are using the same devices.
i myself use 3 different devices, all rooted and running on pac 4.3, always latest nightly, as there are GT-N7100 - GT-I9100 - Nexus 4
not to the point
a) other than most other users i usually clean cache and dalvik cache as well before and after flashing the new rom and/or new nightly
and never encountrer any problems except those which everybody, using the same rom and nightly encounters.
b) whenever i flash an totally different rom and/or upgrade and/or downgrade to another level of android os, i.e. from 4.2.2 to 4.3, i perform
a clean install, including not only a factory reset, but as well a format sd-card, format cache and format system etc., again i cannot proof
which of these steps make a or the differnce but however, i never have problems others than thosw which everyone has with a version.
c) when using cusome kernels and due to the fact that some roms come with a kernel included, as well as with a custom recovery included,
it is strongly recommended not to forget to flas the kernel again after each flashing the new rom. one good example ist dorimanx kernel
for GT-I9100 which will not boot into recovery and reluctantly boot at all after a new flash of a pac nightly without reflashing the kernel.
d) try to fix permissions on reboot instead of doing it from recovery. one reason is that not every recovery has this option and further i
found that when fixing permissions before the first boot after flashing a new rom, there might be bootloops, albeit i cannot explain exactly
why that should, but however, sometimes it's better to be on the safe sid.
e) try to run whether the lastes version of custom recovery for your device, and or the use the included custom recovery of the rom or the
kernel. this again is one thing that can help to avoid some unexpected and hard to explain bootproblems and/or fc's etc.
hope that i could give you some new ideas how to avoid trouble while using custom roms and other hacks

You must use ICS kernel, either unlock bootloader and install custom ICS kernel, or first install/update to stock ICS and then follow the same method.
i already did 6 times
i already tried 6-7 time to install custom rom when it stuck on sony logo i flashed it with orignal stock rom and tried again but every times same problem arise. now i am not understanding where i missed

First install stock ICS firmware, Android 4.0.4 (4.1.B.0.587 or 4.1.B.0.431), and then install the custom ROM. Did you do it so? Can you write the file, which you used?
no..i flashed only base version 4.0.2.A
i always flash "LT18i_4.0.2.A.0.58(2.3.4)_HK" after every bootloop, i not tried to flash 4.1.B.587....few month before tried it to flash but i think it is not able to flash because of system partition is is less because of 4.0.2.................well benifit of installing upgraded rom "4.0.4 (4.1.B.0.587 or 4.1.B.0.431)" and are you sure after that i will able to install it..?

Hey guys,
I'm new to the Xperia Arc development and need some help with installing a custom rom. I've done quite a bit of reading but still can't figure out what is wrong and why it's simply not working.
So from what I gathered the steps to ensure a successful flash are:
Firstly flash a stock rom via flashtool ie LT18i_4.1.B.0.587.ftf
flash LT18i_4.1.A.0.562_Kernel > root the device > flash back to LT15a_4.1.B.0.587_Kernel
Then now that the device is rooted, I need to install a recovery such as CWM via RecoverX
So, so far so good as I can access CWM, stock rom works fine as well
So then next step is to unlock the bootloader
pretty sure this worked, as when i tried to unlock it again, it said it failed as it was already unlocked
Now flash a custom kernel, in this case i flashed the 146 FXP CM kernel
This also seemed successful as I was presented with a custom splash screen
So then after custom kernel is installed I enter recovery, wipe the cache and reset factory settings, format the data system and cache as well as wiping the dalvik and battery stats.
After, I installed the custom rom zip file, in this case it was aokp_anzu-ota-eng.kxp_build5 and then google apps and then reboot.
So my problems begin here.
My phone seems to be stuck in the boot process (sometimes), on the "initiating swagger" splash screen and it goes crazy. I've tried flashing this rom with other kernels (fusion 3.9) and sometimes it actually loads up into the rom. But the rom is extremely laggy, applications freeze and close and the wifi never works
So my question is, is there any steps or procedures that I am missing, not doing right or in the correct order?
I don't think it's any hardware issues as wifi works in the stock rom, and it's fairly smooth and fluid.
Also, is there a better way to flash roms so that I don't need to do this entire process of flashing a stock rom, rooting, unlocking bootloader, installing recovery every time I want to flash a new rom? And when I flash a custom kernel first, then flash a custom rom that has a kernel inbuilt (cm10) does the custom rom's kernel replace the one i just flashed, reason for asking is that the instructions say to flash the custom kernels and then the roms, but yeh just hasn't been working for me so not really sure how to do what.
I'd really appreciated any help or insight!
Thanks

Thanks! I've read your guide (what I based my flashing on) and it seems consistent with what I have done, on the surface of it anyway. If you think I missed or overlooked something, would it be possible to point it out?
If your boot loader is unlocked it's as simple as this...
1. Flash kernel
2. Wipe cache etc
3. Install ROM
...I always reboot before installing anything else as I've found it can break the installation of the ROM.

As ExpirienceD says,just one more thing flash kernel modules if you need to.
So:
1.Flash kernel
2.Full wipe data/cach...etc...

Hey everybody.
I used to flash all sorts of roms on my old galaxy vibrant but I bought a new t989 a few months ago and I want to go to a custom from the stock tmob bloatware infested ICS. I already rooted via odin and installed clockwork recovery, which comes up just fine with the usual volume and power combo so i'm good there.
My question is should I flash my first rom (probably jedi mind trick 5 or x1,or if anyone knows a daily driver ready jelly bean??)
via clockwork mod like on my vibrant? or do I use twrp which I also have via goo manager? I prefer cwm because I am familiar with how to wipe cache, reset and flash with it but I can't figure out why some mods recommend one or the other.
Also,
I keep seeing some roms that come with a radio zip and was wondering if all roms require this or is it just certain roms?
Thanks in advance for any help. I just don't want to wreck my phone the first time. Remember, I've flashed a million times on my vibrant but never on my t989 so any pointers or heads up would be appreciated.
Get darkside wipe scripts (both wipe cache and super wipe)
Go ahead with the Jedi X1 ROM its very stable and fast as hell
But if you want Jelly Bean I recommend Galaxy SBean v8 or Liquidsmooth rc8 they're the most stable JB ROMs from what I experienced
Remember to always wipe dalvic cache and fix permissions (darkside cache wipe) after flashing a new ROM
After you flash your ROM and Gapps then boot that's when you can flash kernels, mods, and apk's so it would have a lesser chance of a soft brick
Happy Flashing!

Cool. Thanks for the reply. I went and grabbed super wipe and cache wipe. So essentially, I just put those two on my sd and flash like I do a rom zip from recovery and then flash the rom itself and do a darkside cache wipe after new rom is installed before restarting and booting for the first time? Do I still need to do factory reset/wipe or is that part of the scripts? I have the goo app so I can use twrp instead since it's recommended for almost all roms I will be installing. Any major reason why, besides that it has touch function and backup renaming? Is it safe to install from the goo app on stock rom?
I think I will probably try one of the jellybean roms you suggested. I just didn't want random reboots, and I heard that's an issue with jelly bean roms but I think that might have been specific to aokp ones or something. Occasional FCs aren't too big of a deal though.
One other thing though... how do I fix permissions? I kept reading about that but never did it. Do you mean in recovery or under superuser?

Ok thanks. He seems to recommend not using the darkside scripts. I have a slightly older CWM 5.0.2.6 that I did via odin BTW so do I fall into the 'don't' use darkside category or does he mean anything after 5.0.2.7? I don't mind wiping cache and dalvik manually and doing all the formats if that's the case.
Do I fix permissions after I have booted the rom and waited 10 mins and restarted back into cwm or before I boot it for the first time?

I usually do it after flashing. And you don't need to do it every single time. Also, there's no need to follow everything down to the letter when you flash, wipe cache/dalvik/factory reset/wipe system/fix permissions/sit for 10 mins/reboot/reboot again/etc. Flashing is like cooking. As long as you don't deviate too much from the recipe, you'll get edible food (or a working ROM). If it doesn't work out, just toss the food out and try again (softbricked phone, reflash). If you try something stupid, you'll set your kitchen on fire when you don't have insurance (comparable to hard bricking your phone).
I usually wait till I've restored all my apps before fixing permissions, and then sometimes I don't if everything is working fine. As for recovery, I know you're familiar with CWM, but I'd recommend spending some time using TWRP. It's really great. You don't need the scripts with TWRP, but since TWRP lets you cue up zips, you can set it to do super wipe, ROM, gapps, and cache wipe all in one go. Kinda cool. And if you're itching to try jelly bean, AOKP JB milestone 1 is stable and smooth. There are even a couple custom kernels for it and CM10 (which has also reached a stable version, though I haven't tried it).

Dark side super wipe and cache wipe work perfectly on 5.0.2.6! That's how I got PACman ROM on my phone. I didn't bother with fix permissions. Well, I would say don't worry unless the instructions specify to do so.
Either way, I like CWM because I used it on my Samsung Galaxy Ace. Its just the wipes are broken for this phone so the scripts have to be used and work perfect. Happy flashing!

no it's fine to use the scripts w/ cwm 5. just don't use the scripts on cwm 6. that's what he meant.
i usually fix permission after the first reboot & waiting 10-15 mins.
i second the twrp recommendation...however if you're flashing something old, then cwm is the way to go. i haven't had any problems flashing anything in cwm. the latest twrp however failed me after i tried to flash a gb theme for jugg lol.

Ok, just wanted to make sure on that one.
Thanks for all the input everybody. Hopefully I will get a chance to do my flash over the holiday. I plan on going with the Sbean V8. Really all of the roms out look excellent but this one looks good for a JB daily driver. I went ahead and downloaded Jedi X1 too though in case the sbean doesn't work out for whatever reason. I have to tether my phone at home for internet so I thought it might be good to have a backup just in case PDAnet doesn't want to work.
Is twrp ok to install from Goo manager on my stock rom or should I flash a new rom and then use it from then on? I just want to make sure it won't conflict with the stocker or the CWM that I have on it already.

Hey guys i have a samsung i747 from rogers and i'm trying to install custom roms. I've obviously rooted it and installed CM recovery and downloaded roms and gapps. So far i've tried liquidsmooth 2.8. Avatar Rom. Cyanogen. but nothing seems to be working. Every single one of the them keeps telling me that my setup wizard had crashed and my gapps weren't working. I earlier had a Status 7 error installing cyano and avatar so i flashed d2att's 07.05.13 kernel, but that didn't seem to help. I tried running a different version of the clockworkmod recovery too. I've hardly ever "dirty" flashed. Someone help me out here i hate custom roms!!!
Wipe
Data
Cache
Delvik Cache
and Factory Reset.
Make sure you're flashing the correct GApps for android 4.2.x
Flashing a kernel has nothing to do with a status 7 error.
A status 7 error points to a outdated recovery or bootloader.
You should get ANY errors.
If you hate flashing why do it??
I honestly don't get that...
If you're here to make your phone to look "cool" you're in the wrong place.

I would get TWRP recovery.. wipe dalvik / factory reset. and re-flash your rom.. I'm on Rogers as well and the status 7 error means that your recovery / bootloader is outdated.
So start by getting the most recent TWRP. I got it from goo.
btw: if you don't like custom rom, i suggest going to the sammobile site and getting your factory firmware. Use Odin to reflash back to stock. That should solve your hiatus towards custom roms...

I'm having issues flashing multiple roms of the 4.x.x Roms. The only rom so far I have been able to install and actually run on my phone is TweakWiz V2. I have tried many other roms and they just stay in a boot loop screen. Examples are with the Avatar rom it just stays on the mask an keeps going and going. I have tried CyanogenMod/Cyan Kang an it just stays on the Circle with the bar going around on the inside.
I am running the TWRP Touch Recovery. I also have the latest Radio update and everything else is updated on my phone.
I also let the install itself run for 10+ minutes everytime. But all the roms I try they keep doing the exact same thing and staying in a boot loop.
Can anyone give me any tips or suggestions to maybe something I could do to use another rom or maybe even a suggestion to something I may have overlooked.. Any help is appreciated. Thank you.
An if you need me to give any other information let me know an I will provide.

1.Im using the latest TWRP.
2. Wiping System, Cache, Dvalik or whatever. I wipe everything in the usual instructions. And I make a backup of previous ROM. Flash the ROM then the G-Apps.
3. After I flash I let the ROM run its course an I wait from 15-45 mins for the ROM to load if it doesnt I switch back to TweakWiz or try another.

try using this recovery since the recovery you are using is the latest one and technically for 4.3 ROMs, give this a shot http://techerrata.com/file/twrp2/hercules/openrecovery-twrp-2.5.0.0-hercules.tar its the same recovery but lower . the steps you clarified seem very proper but your recovery may be at fault crossing fingers try flashing that recovery through odin or download the zip from the same website and report back after trying to flash again
Are you sure you are wiping DATA also?
You will need to do this, if you are flashing a 4.2 or 4.3 ROM, then you will also want to wipe the pre-load. Then flash the rom, and gapps.
Use the newest TWRP 2.6.1.0 to flash anything, don't need an older recovery to flash older ROM's.
