[Vibrant Q&A, Help & Troubleshooting] asher_pa:
Hello friends.

I'm kind of new in "switching rom's" (I have vibrant for 4 months and still use my first rom project-v=> wonderful rom.)

I'm looking for the principle that guides me about "switching rom's" like:

1. If I have project-v rom (2.2 BL) and I want to move to CM7 rom why moving to stock not needed.

2. If I want to move to 2.3 XXJVX\T Rom I need to flash stock first, WHY?

3. What is the best way to flash stock (Is there any rom that already rooted and CWR installed that can be flash from odin once, from there continue like the 2.2 steps)

4. If I have voodoo and I want to switch rom (CM7 \ XXJVX\T) should I disable it or uninstall it?

5. What are the CRITICAL phone files that I need to backup before flash and how (I read something about EFS folder)?

6. What are the common problems that I need to notice when switching Rom to do not hard brick my phone (I know that If I'll flash 2.3 rom with 2.2 BL it can brick my phone OR flash rom that contain SLB.Bin or Boot.Bin with Odin)

I'm looking at this site and other sites but I couldn't find and satisfactory information (I'm not planning to create rom's but I just want to know what am I doing before doing it => I don’t want to brick my phone at the first flashing)

p.s

One thing that I found in this site that moving from 2.2 rom to another 2.2 rom need to use this steps:

Copy rom to sd card

wipe cache partition

wipe data \ factory reset

wipe dalvik cache

install zip from sdcard

Any information will be appreciated.

Thanks.

[Vibrant Q&A, Help & Troubleshooting] trailblazerz11:
1. and 2. I flash stock for a clean install when 2.2 to 2.3 or CM7 Miui.

3. I just Odin the stock firmware and use update.zip method to install CWM and then rom

4. Depends on Rom you are flashing too. If they support voodoo sometimes you won't have to disable voodoo, read OP and posts to confirm.

5. Besides pics music and app data, IMEI is most important though its on back of phone. Personally I throw everything on my phone onto my computer, just in case it bootloops and wipes sd.

6.Usually its just soft bricks,easily fixed with download mode/ODIN or just recovery. Only time I've hard bricked was using Samsung's Kies mini....(make sure GB bootloaders for 2.3 roms, otherwise rainbows in recovery)

~on p.s. Yes you want to do that so you don't get force closes and lag moving to different rom (you can skip factory reset if upgrading new version ROM usually, but read OP.)

Also read the guide sticked on Q&A, his other guides are good too.....
[Vibrant Q&A, Help & Troubleshooting] kaintfm:
I COULD answer your questions. The reason I can answer your questions is because I read the stickied threads in the development forums as well as any and all relevant information in the threads of the ROMS and kernels and modems I wanted to flash.

I suggest you do the same, but first, watch this Youtube video.

So much wisdom But with that So much bragging

Many thanks for your help it was very comprehensiveץ
[Vibrant Q&A, Help & Troubleshooting] kaintfm:
Bragging? What are we bragging about? Being able to read?
[Vibrant Q&A, Help & Troubleshooting] asher_pa:
as I already told you I read all the guides and FAQ and I understand "What to do" but what I wanted to know is "What I do"....

I think that if I will know what am I doing I will decrease the chance to brick...

(for examples:

1. when in OP it say "came from other \ costume ROM" does it mean to 2.2 rom too

2. in the "back to stock" guide in the stick posts.. => does the "stock rom" is 2.2 \ 2.3 bl?)

again...

for you guys that doing this 5 times in day it sound obvious but for me ... :-(

but for summarize:

you doing wonderful job. Thanks.
[Vibrant Q&A, Help & Troubleshooting] MizSxxyBych:
Lol

Dude, I spent DAYS reading...and I mean DAYS... When I thought I read enough, I started and bricked my phone. Then again spent hours reading MORE, until I finally unbricked my phone....and started over. Even now, I still have to read read read to understand, and STILL don't...

It's frustrating for those who put in all that time to see posts from people who don't want to take the time to read... And we see it all the time. If you can't find the information here...something is wrong.

[Vibrant Q&A, Help & Troubleshooting] kaintfm:
What Miz said.

Not sure if you're lazy, or just the language barrier getting in the way, but if you're still confused after reading through our development forum and sticky posts, you should either:

A) Do not flash a ROM, root your phone, or alter your phone in any way. Stick with stock.

B) Try to find a guide that's in your native language. XDA is pretty much English only.
[HTC Sensation] DakuGaranto:
You know everytime a new rom is flash (Super wiped) all the widgets, folders and apps I customized will all disappeared/gone/reseted and i will need to redo the customization all over again. Is there a apps or a way to backup this and restore each time after flashing a new rom.

Using ARHD sense 3.5

Thanks

[HTC Sensation] Modriin:
As far as I know you can't backup the widgets and Folders.

But you can backup the apps (+Data). I use Titanium Backup Pro to Backup and restore my apps.

I tried this app but my home screens werent restored.

Could you expand where this setting is on the app?

EDIT just did it in titaniumBU! you need to restore the DESKTOP HTC SENSE XXXX.

For some reason it doesnt do it while doing a batch restore, the icons are all back (whoch saves a lot of time), the wallpaper and the widgets need to be readded.

Task killers is there any advantage on using them ? Currently I am using one that kills as I lock my phone although in theory these apps are just booting back up in the background (services that is) isn't that hogging resources in its own right ?

So my question is do you use a task killer ?

Cheers
[Galaxy S II Q&A, Help & Troubleshooting] brahmy:
The consensus is that they're not useful. Use the back button to quit apps, and a battery monitor to monitor apps that abuse power.

If you see apps taking up RAM, that's a good thing - RAM is supposed to be utilized so that the phone can launch apps faster.
[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
Do not use task killers! :)

Our beloved gs2 has lotsa memory and android's memory management is very powerful. So don't worry about ram usage. When the device runs out of ram/after an app is no longer required to be kept in memory, inactive and finished apps are removed from memory automatically.

Most of the apps, after exit are kept in memory for a faster launch next time. Idle apps doesn't consume any cpu or battery.

If you're worried about your cpu usage and battery drain, use watchdog from market to monitor misbehaving apps.

Use betterbatterystats to monitor what apps/services are causing wakelocks.

http://xdaforums.com/show....php?t=1179809

Then you can adjust the settings/uninstall apps that's causing battery drain.

A con that many of us have seen is lost ability to tether over USB due to the computer not recognizing the phone while it is in QT Composite USB mode. Some however have continued success. My guess is that this is either related to the continued discrepancies in firmware versions that some of us have or it is due to some of us having 64bit Windows vs 32 bit.

Hi

does anybody know, if official miui is based on ext4 and if not, is there any way to convert it?

thx for answers
[Galaxy S I9000 Q&A, Help & Troubleshooting] Mr Woolf:
Mate, you really should use the search function. This is the second time I've answered this question recently.

Ext2/4 lagfixes (including voodoo) are used due to the slow speed of the rfs file system which samsung decided to use.

MIUI is cyanogenmod based, and as such, uses yaffs file system. Yaffs is quicker than ext2/4 so other lagfix solutions are unnecessary and incompatible.

Hope this helps.
[HTC Sensation] unfnknblvbl:
First of all, apologies if this is in the wrong section!

Secondly, do not flash these zips if you expect things to work!.

Thirdly, I'm not a developer. I couldn't program my way out of a wet paper bag. That doesn't stop me from wanting to hack things up though :D

Now that that's out of the way, I've been trying to get a flashable, bootable ICS update.zip happening for Sensation. Why? Because emulators suck, and I want to play with ICS on real hardware. Also, because it's in progress on other phones, and I've seen no activity regarding it on Sensation yet - despite us having the coolest phone on the block ;)

The first thing I did was to pull apart the SDK image using dsixda's wonderful Kitchen tool.

It's been a while since I dabbled in porting ROMs around the place; I haven't had an HTC device for over a year now, so my first instinct was to then pick apart things from working ROMs and mash them into the ICS tree. Merging the .prop files, adding libs, etc. I nicked everything from CM7 for Sensation.

The zips generated this way flash but don't boot. Fun!

Then I read Siulmagic's guide to porting ICS. Brilliant, how come I never thought of doing that? Ah right, not a dev. That's why.

This time I decide not to mash in anything from CM7. Just leave all the ICS files as they are and only add in the modified boot.img.

The problem here is that now the zips refuse to flash. They all fail with "(status 0)" for some unknown reason.

I don't have the patience to try to debug that particular issue, so my next step is to flash the modified boot.img and system.img files using fastboot.

Aside from the damned barrel of laughs I had trying to get that little trick working, I still have no success. Still stuck at the HTC logo screen with no logcat to see what's going on.

My last brilliant idea is to grab one of the first update.zip files I created (with just the mishmash of stuff from CM7) and replace the boot.img in it.

That flashes OK, but again I'm stuck at the HTC logo again. And still with no logcat!

Anyway, that's where I'm up to for the moment, and so here's the last two files I came up with before giving up for the night:

- modified boot.img + plain /system only

- modified boot.img + file mashup

I hope we can build on this - or at the very least, that I'll learn just WTF I'm doing wrong. :D

MOD EDIT: Deleted links as even with your warnings people will still flash.

Also, this thread belongs in General until a BETA of a ROM is ready
[HTC Sensation] unfnknblvbl:
Idea for tomorrow: try a modified Sense kernel and see if that works.
[HTC Sensation] krogoth:
Try AOSP Bricked kernel, but AFAIK ICS is using other kernel than GB.

[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Hi

OK, I have just received my Atrix, and am having trouble. Basically, it will not connect to mobile data.

It is an AT&T model, unlocked to all networks by the seller. I can make & receive phone calls (now I've found how to skip Blur setup), and have entered the correct APN settings, but it refuses to connect.

I am assuming this is a radio/frequency issue. Are there any radio images that can be used to correct this, so I can use this in the UK? On the Defy there is an app called "baseband switcher" which can install the correct info for you.

---------- SOLVED ----------

Just a quick edit to show this issue is fixed.

I am unsure what fixed it. I have performed most of my testing at work, and found that the issue here was a problem with my provider (they were doing maintenance in the area). But it didn't work at home either, initially. I have flashed several radios, modified pppd-ril.options and replaced libmoto-ril.so. Something out of these has fixed my issue.

If I get chance I will remove some of the mods to see if the issue comes back, and post the results here for anyone else who comes accross this problem.

By the way, this has only fixed the issue of no 2G data. 3G data on 900MHz is still unavailable, as far as I am aware. If anyone knows how to check which frequency is currently being used, I can check this further, otherwise I think this is the best we can hope for at the moment.
[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Hi

Does anyone know the answer to this?

Can I flash a UK/European radio on this (AT&T) Atrix? I have installed Aura, will this make a difference? Are there "fruitcakes" available for the radio, or must I use and SBF?

I have tried to research this through the site (and google) but I can find no definitive answers. All I think I need is a 900/1800/2100 baseband. I definately have the correct APN settings, and mobile data has worked while I've been out and about, but it is very patchy and I am not getting mobile data in places I know have good signal, and am noit getting 3G in places I used to.

I had this same problem on my Defy, and this was easily fixed using the Defy Baseband Switcher app. Selecting a UK baseband fixed all my issues then, so I expect the same now.

Please help

Thanks

[Atrix 4G Q&A, Help & Troubleshooting] is95kiko:
Hello

I'm interested at the answer too. I have bought AT&T version from US and imported it to Europe.

The problem for me is that I need Atrix to use 900MHz 3G. I can use 2100MHz 3G but when the 3G is build using 900MHz, Atrix is not able to use 3G, only Edge or GPRS. I have other phone with 900MHz/2100MHz support which I use to verify existence of 3G service.

I have tried with radio version N_01.95.00R which did not work with 900MHz. Just couple of minutes ago I installed N_01.100.00R (CWM zip), haven't yet tested it with 900MHz.

I have seen reports from users owning Atrix, that they have been able to activate 900MHz 3G support by installing N_01.95.00R or N_01.97.00R.

If N_01.100.00R does not work, I''ll try N_01.97.00R and after that I don't know what to try.
[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Thanks, that's more info than I've managed to glean from my research.

I'm also on a network which uses 900MHz for 3G (in some areas at least) so this may be my problem. I'm currently on baseband N_01.77.15P. If you wouldn't mind letting me know once you've checked I'll wait for you to report back about

N_01.100.00R.

By the way, does anyone know if there are these "fruitcake" things for radios, or do they have to be flashed from SBFs?
[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Just FYI, I got impatient, and work has been quiet, so I tried myself.

1.100.0R and 1.95.0R made no difference for me.

I also tried an international 1.97.0R SBF, and this gave me an error while flashing... was quite worried till I pulled the battery and it booted back up fine.

I just want to add, here, that if I manage to get 3G reception I can use it fine. However I don't get 3G in very many places, including ones which worked perfectly (full signal) on my Defy. Also, as soon as it tips over to 2G in these places, it shows the "G" icon but does not allow any traffic.

As I said, this is exact problem I had with my Defy when a ROM I installed changed the baseband to a US one from a UK one, and it was fixed as soon as I changed back. So "all" I need is a baseband which will install on my (BL unlocked, SIM unlocked, Rooted and ROMed) AT&T Atrix which is compatible with (O2) UK bands (specifically 900MHz for 2G & 3G and 2100MHZ for 3G only).
[Atrix 4G Q&A, Help & Troubleshooting] is95kiko:
I tested with N_01.100.00R, but no success.

I don't know anything about "fruitcake", but I have installed new radio versions either from sbf with RSD Lite or from zip-files using CWM.

Where to find radio versions made for Europe/international use?
[Atrix 4G Q&A, Help & Troubleshooting] Vangelis13:
I have an AT&T Atrix in Germany, everything works out ok. Try following:

Go to http://xdaforums.com/showthread.php?t=1163009 and flash the radio from there.

In your stock dialer, dial *#*#4636#*#*, choose Phone Information, Set preferred network type to "GSM auto (PRL)" or "GSM Only".

Before all that though, make sure you have the correct APN, it'd be a bummer if it's that simple.. :-)
[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Hi

Thanks. I have checked the APN settings so many times now that I could probably recite them by heart :) I have also installed an app which sets up the correct settings for me, so I'm pretty sure they are right. From *#*#4636#*#* network type is set to GSM auto, and "GSM disconnects" says "fail because Unknown Data Error".

Which radio from that post, BTW? The AT&T .91 one?
[Atrix 4G Q&A, Help & Troubleshooting] Vangelis13:
Yep, that's the one I'm using.

Try flashing that and see how it goes. Though data should work regardless older / newer radio; have you tried calling your provider?
[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Nup :(

Flashed the linked radio, and it made no difference.

By the way, I finally found where the "Select band" item was, it's in the 4636 menu, phone info, menu key, select band. This shows only USA.

I think I may try flashing the French fruitcake located here just to see if that fixes it. Orange France uses the same frequencies. I know it's stock, but I can try flashing a custom ROM after. I just want to get this thing working now...

Also, there is a post here which seems to suggest a method to fix it, but I am at work and it's too much hassle to set all that up here.
[Atrix 4G Q&A, Help & Troubleshooting] is95kiko:
I tried to flash couple of international sbf's but none installed, sec_exception febe 35,35 was the problem.

Then I tried to install Bell radio from bellradiolatest.zip using CMW. Now I have version n_01.77.30s.qn, haven't tried 900MHz yet but 2100MHZ is working as it was with other versions.

4636 menu shows me also the USA Band, which is only option, cannot be changed.

After I have verified that this n_01.77.30s.qn ain't working, I'll try AT&T .91.

I'm using Cyanogenmod and prefer it, I just can't stand the original firmware or something based on original one. For example, week starts from Monday here, in CM I can choose it but US based firmwares week starts from sunday and cannot be changed.

Never heard of a carrier disabling a network they already have, but why would you be worried?
[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
That sucks!

Anyway, the reason I was wonderring is that I cannot get a 2G data connection either. I have been told now on another forum that this is not the case, and I should be getting 2G data. So it seems the phone cannot even make a 2G data connection at 900MHZ (this network only does 2G at 900MHz, 3G is at 900/2100MHz). In *#*#4636#*#* it shows DcAtivatingState for ages, then goes inactive with "Unknown Data Error".

When I can get a 3G signal it is fine.

[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Now it's just gone into DcActiveState, and says the connection is available. However, nothing gets through. It reckons it's sending and receiving PPP packets, but I can't ping anything, can't nslookup, and obviously can't browse.

Just tried with my old phone, and everything looks the same (when restricted to 2G only), and it operates perfectly. So it is the phone. I checked the APN settings again, before you ask, and they are identical between devices.

I did read something about the stock AT&T firmware blocking other APNs, but that can't be what's happenning here, can it? I mean, it works fine when it can get 3G.
[Atrix 4G Q&A, Help & Troubleshooting] drmouse81:
Right, this is getting irritating.

I just flashed a stock 2.3.4 fruit cake to see if that helped. I added my APN settings, and couldn't connect. Set it in WCDMA only and it got a weak HSPA signal, went through Blur setup. Tried again on GSM auto and no joy, even when it hits DcActivatedState nothing gets through.

I am absolutely certain it is not the APN settings. I am sure they would not even allow 3G access if they were wrong, but with a 3G signal it works perfectly. But on GPRS (in several places, miles apart so on different cells) I can get not data connection.
