Bootloops in CM7 after MIUI

I've been using cm7 pretty much since I got my g2, but recent problems with gps caused me to look for other options.. so within the latest clockwork recovery I wiped data and cache for cm7 and flashed the latest miui rom. When I decided to go back to cm7 I wiped everything like before and flashed the rc2 rom. Even after repeated flashing I can not get the bootloops to stop. Right now I'm running cm6.1.1 with no problems.. but I would really like to find a way to bet back to 7.

[Q] Concerning KingsROM Ultra BeatDown GB-R4

I am currently running EvoKings GB RC3 and loving it. But since I can't leave well enough alone, I want to update to the RC4.
I just have a couple of questions concerning this ROM.... I see where he mentions its based on CM7... is it based on CM7 7.0.0.0 or CM 7 7.0.2.1?
Also will I need to do the GPS fix again and update PRL, as I assume I have to wipe dalvik/cache to update from RC3 to RC4 (as it seems its more than just an update)?
Speaking of the GPS fix, when I did it, I was on RC3 of the EvoKings GB rom, and this is the steps I followed:
Booted into recovery
Made a Nandroid backup
Wiped All Data
Flashed into a backup sense rom I have (Mikfroyo 4.6)
Performed GPS fix and updated PRL
Booted back into recovery
Performed Nandroid restore (no data wipe)
Back into RC3
Was that correct... that I dont do a data wipe and just do a nandroid restore? I have been reading so many conflicting reports on this. My assumtion was to always wipe data before doing a restore.
Thanks everyone.

First of all, if you're updating a current rom, them all you should have to do is wipe cache & dalvik and then flash the updated rom. As for not wiping data, no, it isn't necessary, however, I'm one of the people who do especially if I'm changing roms. I don't want any remnants of the previous rom.

Ok cool, thanks. When doing the GPS fix, is the info stored somewhere else, which is why it doesnt get removed when doing a wipe of stuff?
Trying to figure that out... since yeah I am worried about having some type of conflict when switching from a sense to an AOSP rom. I havent had any issues so far with RC3 doing that, minus some issues with the screen not coming on with a button press while playing music.. but not sure if thats just something with the ROM itself or the GPS fix.

I am not sure where the gps fix is stored, but there should be no conflicts. I have switched between AOSP and Sense tons many times since I did the fix and have never had any problems.

+1.....I've never had to apply a GPS fix and I, too, have switched between AOSP and Sense numerous times. As a matter of fact, my current rom is Salvage-Mod and the GPS works as it should and I still didn't have to apply a fix.

I had to do the gps fix when I first switched to cm7 rc2. Since then I have never had to redo it nor have I had any issues.

What build of CM 7 is this rom built off of?

[q] CM7 upgades?

Having never used CM7, I'm not totally sure how the builds work. If I want to use the nightlies, or flash the next beta when it is released, do i need to wipe the phone each time? I'm hoping it's like roms i've used in the past on my fascinate that required at most clearing the dalvik.

It's answered on the last page of the cm7 nightlys thread.

no wipe
for the nightly and rc%, each build can replace the old with no wiping or data loss.

Flash 10.3 on CM7?

I flashed one of the nightlies of CM7. Loved everything about it. Everything was snappy. But when trying to view flash videos I could hear but no video. Wiped everything reflashed the next nightly and same issue. Does anyone know of a fix? I'm running a gingersense ROM at the moment but would love to be able to use CM7 with some sort of flash fix.

[Q] Downgrade from CM7.2 to CM7.1

Has anyone downgraded from CM7.2 to CM7.1? For some reason CM7.1 seems much more stable on my phone. Is downgrading as easy as upgrading?

You need to install a stock rom, flash clockworkmod, then flash cm7.1.
But you can make a backup, wipe data cache and dalvik and flash cm7.1, without stock rom flashed..
But why would you?
I think 7.2 is better..

Well, I tried 7.2 on my phone and it is not as stable as 7.1 for me. I am constantly having problems connecting to my home wifi network (have to enable/disable the wifi adapter a couple of times), phone restarts from time to time for no reason, unlock screen blinks one time before it t actually appears on screen and some other minor issues. Didn't have any of these issues with CM 7.1 so I think of going back to it. I'll probably go go for the wipe cache/dalvik solution in that case. Thanks for your reply.

Did you patch CM 7.2 with patch 4? The patch fixes most of the things and the rom is the most stable for me.

Yes, I did. Did I need to wipe something before or after applying it?

Update: I've just tried to wipe the cache partition plus the dalvik cache and it seems that most of the problems are gone now. I would recommend doing this to anyone with the same issues as mine.

You always have to wipe the cache/factory reset and dalvik cache before installing a new rom otherwise problems will obviously occur.
Glad that you solved the problem. If you still face some problems then wipe the cache/factory reset and the dalvik cache and flash the rom again with patch 4 and gapps.

I use stock rom, better than CM7.2/7.1. No lags in games, no screen flicker, no f****n problems. Same performance and better battery life.

Stock rom with custom kernel??
Sent from my GT-S5660 using xda premium

Nope, just stock rom with root and some stock apps deleted, that's all. Maybe i will flash the kernel for stock roms, maybe.

What benchmark results do you get with the stock ROM (either Quadrant or Antutu)?

Assuming you really want to downgrade to CM7.1 I think you can format /system, /data and such from CWM, then apply CM7.1 zip file. No need to install stock ROM first.
BTW I saw in CM-related instructions that when you have some problem with CM that you don't know how to fix try first doing wipe, usually that helps. It seems it helps in your case as well

Yeah, that's right

Dude, leave the f***in benchmarks, my phone is faster in games. With CM 7.2 last time my result in quadrant was 2600, but it was bulls**t cause i had lag in games.

Yup, I also find benchmarks are useful for bragging only. They almost never tell anything real about phone performance in a real application.
So you have to try different ROMs to find the one that would suit you.

Well, I guess it depends on what one uses his phone for I don't play any games and my phone is definitely faster with CM7.2. But as JustVass said everyone has to find the one that best suits him
