[Q] Flashing from CM7 nightlies to a different ROM?

Hi everybody....Ive been flashing ROMs from ROM Manager and never had problems...until I tried to flash from CM7 nightlies #66 to a leaked G2 ROM][04/28/11] TMOUS G2 Gingerbread 2.13.531.5.
I did the usual wipe cache and dalvik and proceeded, it seemed like it was downloaded but got stuck on the reboot, it was stuck on the HTC logo for a long time. I thought I bricked it but managed to get it to work by taking the batterie out and going into recovery by clockworkmod.
Is there any special way to flash ROMs from the nightlies on a G2?

You said you wiped cache and dalvik, but did you wipe data too(factory reset)? Pretty sure you need to do that if coming from cm to the stock tmo leak. Could be wrong but sounds about right

that is right anytime change roms that are not linear to the same dev, it is best to wipe all, data/factory/cache then flash rom

Hmm, I checked everything that ROM Manager suggested, cache/ dalvik, the only thing I didnt check is to back up current ROM.
If you wanna wipe all that data/factory/cache do yo have to flash it manually?

Flashing other roms I think messed up my phone lol. I just stay with cm7 now lol
Nonsense!

even if you did say to wipe /system and /data in addition to /cache, CWM is notorious for not actually formatting the partition. go into the dev section and find SuperwipeG2 and if you are switching from aosp<->sense or, as earlier mentioned, from one dev's rom to another, run superwipe before doing so.

[Q] Custom Roms / Kernel Questions

I have a AT&T Samsung Galaxy S3 (SGH-1747) that is running stock with root.
I have rooted my phone using the samsung toolkit located here: http://forum.xda-developers.com/showthread.php?t=1746665
Since that toolkit flashed a CWM Based recovery I have installed ROM Manager and flashed CWM Recovery version 6.0.1.2
My questions are..
- with my current setup.. am I technically running the "Stock" samsung kernel?
- why would you want to flash a different kernel to your phone?
- and is it necessary to flash a different kernel in order to use certain custom roms?
- At first I was leaning towards flashing CM10 nightly but the more I look at it.. I want to flash PARANOIDANDROID 2.22 http://forum.xda-developers.com/showthread.php?t=1818199
Is this rom fully compatible with my AT&T phone? and since i'm running stock with root, do I need to do anything special before flashing this rom? Factory reset? Wipe Data? I've already made a full nandroid backup.
Thank you!

- with my current setup.. am I technically running the "Stock" samsung kernel? I believe so
- why would you want to flash a different kernel to your phone? Different kernels do different things.. some have better batter life.. some let you OC and UC..
- and is it necessary to flash a different kernel in order to use certain custom roms?Well sometimes.. Well technically.. most kernels will work with most of the ROMS out there.. as long as you stay withing your phones threads.. But some ROMs have a kernal with them.. and some ROMS you need to flash your own kernel..

Thank you for the reply.
On the rom i'm wanting to flash for my SGH-i747 http://forum.xda-developers.com/showthread.php?t=1818199
The steps for flashing are as follows:
CWM: Install Zip: Rom: Download Here Make sure the file you download is PA-2.22-d2att.zip
CWM: Install Zip: Gapps: Download (These are the new ones)
CWM: Wipe Data/Factory Reset
CWM: Advanced/Wipe Dalvik Cache
Reboot and edit your Apps Dpi & Layout under Settings/Paranoid Settings - DO NOT RESTORE YOUR OLD PROPERTIES FOR NOW
Would i need to wipe data, factory reset, then also wipe dalvik cache BEFORE I install the rom and gapps since i'm running stock with root?
Thank you

i'm also reading that for paranoidandroid you must first flash CM10 then flash paranoid.. is this accurate?

umm.. not sure where you saw that you need to flash a CM rom before flashing the paranoid ROM..
I believe the Paranoid rom is based off CM
The instruction on the link you have, in my opinion, is wrong..
The way that i flash my roms is...
Wipe data/factory reset..
Wipe Cache
Wipe Dalvik
Format/Data
Fomat/System ( i think deletes backups) only do in emergency.aka optional step
Flash ROM
Flash Gapps.
THATS IT
Some people will wipe cache afer flashing a rom..
But if you wipe data/factory reset i believe deletes the ROM...

If you are already running CM10 then you don't need to wipe Cache. Just dalvik and data. Im pretty sure thats what was confusing, since this is based off of CM10.

yeah, I just keep reading and reading.. probably making this out to be more difficult than it really is just don't want to end up with a brick or anything.
I'm already on stock + root + latest CWM so I just need to put the files on my phone and flash but I believe these are the steps i need to take:
1- Download ROM and Gapps to internal sd card
2- Boot phone into recovery
3- WIPE Cache/Delvik/Data factory reset> Mounts and Storage- format system
4- Flash ROM and Gapps

[Q] [Arc S] Installing any JB - same problem

I have a problem with the installation of JB. No matter what ROM I install, after boot, when home screen appear, my touch screen does not respond. I've tried a lot of roms and a lot of kernels. I have unlocked BL. In stock rom I have no problems.
What could be causing this? Should I format system before installing rom via recovery or just wipe data, cache and dalvik? When I should flash kernel? Before/after installing rom? I care about CM10. Plz help.
P.S. sorry for my english

I have Neo,and this is how i'm installing it: first wipe everything (data,wipe cache and Dalvik cache),flash the rom,and then flash the kernel.

I've tried to do that way but but not succeed

Certain ROMs require phone-specific patch, make sure you install it!
Other ROMs have different downloads for different phones, make sure to download correct one!
If you install wrong phone ROM, touch dies.

All question threads belong here in Q&A so please post in the correct sections going forward.
Thanks

The problem is caused by the kernal. You MUST have JB kernel to flash any JB ROM. Generally, for each ROM you will find the recommended kernel and the required steps. Do exactly like posted by OP.
As an example, see here: http://forum.xda-developers.com/showthread.php?t=1979829
You can make an idea on the steps to follow.

Ok, so now I have installed Xperia T rom (7.0.A.3.195 v6.0 for ARC/ARC-S). Should I flash V77 baseband, then flash kernel from CM10 FXP150 pack via fastboot, make a wipe (data, cache, dalvik) then install ROM via Recovery, and then install GAPPS and it should work? This is what i'm gonna do, so if I'm wrong please tell me.
EDIT:
(edited in case someone had same problem)
I found the solution:
I had to flash BB 72 and libs, then flash ROM+GAPPS and libs once again, then everything works awesome. (edited in case someone had same problem)

I'd got a touch screen problem.
Could you please tell me that how can i flash 'libs once again' So, I can try on my Arc.
Thank you very much.

[Q] Question about installing custom ROM

Hello and thank you for reading.
So I got an HTC One V almost a week ago and I'm digging it so far. I unlocked the bootloader, rooted it and then went to install a recovery. First I tried CWM because that's what I used on my Optimus V, but it didn't work. Then I gave TWRP a shot which was awesome because not only did it work, but I also thought the touch option was a nice addition to the recovery. So I found a Jellybean ROM for the One V and gapps, put them on my sd and went to flash them. Wiped Cache and Dalvik Cache just fine, but when I went to wipe the system I got an error message. Ended up soft bricking then spent another hour or so getting the stock ROM back on there. The next day I unlocked and rooted again and I even found a CWM recovery that worked. Wiped everything fine then went to install, but once again I softbricked.
So that being said, here's my question. What step am I missing? I thought I was following all the instructions, but I missed something, right?

you have to factory reset from bootloader

Thanks for your reply. Please correct me if I'm wrong about the order of things here:
Go into my recovery, wipe cache, wipe dalvik cache, reboot into bootloader, factory reset, reboot to go into recovery again, flash ROM and gapps then reboot system
I came across something that said I had to flash the boot img that came with the ROM too so I guess that would be my last step. Sorry if it seems like a total noob question, I'm still learning. Once again your help is appreciated.

Yes flash to boot.IMG for cm10

Flash with latest kernel
hit thanks if I helped u!!!

You guys are awesome! I just want to double check and make sure I have the order right, though because this would be the third attempt and I don't want to have to go through the process of installing the stock ROM, unlocking and re-rooting of the phone again. Even though it's easy, it's still a bit of a pain, you know?
So...
-recovery
-wipe cache
-wipe dalvik cache
-reboot into bootloader
-factory reset
-reboot to go into recovery again
-flash ROM and gapps then reboot system
-flash boot.img (in bootloader I'm assuming?)
-flash kernel (Once again..bootloader, right? I heard Hellboy was decent, but I'm going to read about that now)
I know it's kind of a pain, but a list in the correct order is the best thing for someone still somewhat new to this like myself. If there's something out of order or I'm flashing something in the wrong section, I'd like to know before I do it rather than find out the hard way :laugh: Once again, thanks for the replies. The person that got me into this suggested this forum over all others and I'm happy he did.

Do these steps in order-
1. Put rom+gapps in root of sdcard.
2. Boot into bootloader and select fastboot then connect phone to pc or lappy.it should say fastboot USB.
3. Now flash the latest updated kernel.
4. Then go into recovery from bootloader and factory reset,wipe cache partition and wipe dalvik cache.
5. Then flash rom.zip,boot into rom.
6. Then again boot into recovery and flash gapps.

Factory reset never seemed to work when I did it in recovery mode. Though I was skipping a few steps when I tried it so I'll give this a shot during the weekend and get back to you. Funny thing is I posted a reply as you posted your's :laugh:

CDMA, sorry for not being more specific about that.

Oh thats where u r going wrong!
Download the proper cdma kernel and rom! Use cm10+jmz primoc!
And use the recovery for Primoc! If u flash gsm images to ur cdma phone u will regret it!
Sent from my HTC One V using xda app-developers app

Depends on the ROM
First thing, for cdma, TWRP seems to work better so you're better off using that. After that, it depends on the ROM. I've found that AOKP is the easiest to flash. Get the AOKP ROM and the gpps, extract the boot.img from the rom. Boot to recovery, wipe everything from there (including factory reset so you don't have to go back to bootloader for that) flash rom and gapps, go to bootloader, flash the boot.img through fastboot then reboot. For other roms you have slightly different processes you have to follow. You can find the info on the thread for each

[Q] Keeps looping after flash

Hi all, I had flashed successfully before but wanted to flash to a JB rom. I wiped and flashed, but then it just keeps looping the Samsung load screen, then I see the loading bar... and it reboots and goes back to the loading bar... Did I mess something up? Or is it suppose to do this the first time?
Sometimes it gets as far as the t-mobile 4G screen and the loops back again...
Thanks

What did you wipe?

And what did you wipe with?
If you used an older clockwork mod recovery, you probably need to update your recovery or get one of the updated wipe scripts on this forum.

I tried to flash Infamous S2 as well as Jedi Mind Trick. After more reading, I also flashed the "wipe" zip file that was linked. After I flashed that clean wipe, all is well. For some reason when I did the usual wipe wipe (with CWM), stuff probably didn't get over written.
All is well and working smoothly now with Jedi Mind Trick

it's a combination of how partition gets accessed vs custom recovery(in this case type of wipe) that cause that bootloop.
Provided you didnt have a bad download(.zip bein flashed) If it's a custom ROM suffice to say u need Darkside super wipe.
Unless its a stock (modded) ROM then Infamous super wipe is the way to go.
Hit thanks if/when it helped.
