[Q] Q&A for MT4G NEED LOTS OF HELP!!!!

ok i am going insane right now cuz i have no idea if my phone is completly done for so im asking for your help.... first i had dl ROM manger and had reboot into recovery, then in recovery i backup my phone, then after all that i flash a zip file and reboot system.....when it turn back on it just went to the mytouch 4g startup and then turn off and back on, over and over... so i try to recover, factory rest, and all that stuff and nothing work all it did was stay stuck on that screen.....so can anyone please help me out..i really appreciate it and please help me!!!!
-thanks

Ok, not a big deal, you are probably just using the wrong recovery for the ROM you flashed. I'm assuming you flashed recovery version 3.0.0.5 in clockworkmod because that is the latest one. When using this recovery you have to flash a 2.3.3 (gingerbread ROM) such as CM7. If you were trying to flash a 2.2 (Froyo ROM) such as Iced Glacier, or the stock ROM, you will get the boot loops. What you can do is flash CM7, which is a great ROM by the way. This will at least let you use your phone. Then you can go to the HTC Glacier forum on XDA, go into the android development section, and flash recovery version 3.0.0.6 which will allow you to flash back and forth between gingerbread and froyo. It is not available through ROM manager since we have one of the very few phones that need different recovery versions to flash back and forth.

ok thank you but how do i dl the froyo rom cuz i cant seem to dl the link, sorry for the noob question im just new to this phone

Ok, like I said, the first step is to get the 3.0.0.6 recovery which is the only way you will be able to download a froyo based ROM. If you want to go back to stock, you should unroot, because stock and root do not get along well on the MT4G. As far as a froyo based ROM, you can flash Iced Glacier or Royal Glacier which are stock based just faster and without all of the T-Mobile bloat apps. But if you are not familiar with ADB and Fastboot, you will need to flash a gingerbread ROM first. You should really be reading in the MT4G/HTC Glacier section of XDA, you will find answers to all of your questions. And like I said, don't panic, your phone is fine, and it is an easy fix.

sorry very new to this but thanks alot, i highly appreciate the help..but i have one more question if i format my sd card will it effect my custom rom and everything, like if i happen to start it back up

[Q][GT-i9020a] How do I reflash back to factory?

Hi, new Android user here.
I was trying to root my Nexus S phone yesterday and I'm having problems. There is a lot of rooting guides out there and I used one from xda and also one from unlockr.com. Managed to root the phone ok (I think), but everytime I flash a custom ROM, the phone won't start at all, it just sits at the boot up screen and repeats itself.
So I'm thinking, I should just start over again. So I flash the stock ROM from xda back to 2.3.1. Everything seems ok, the phone starts up... but it's always stuck on airplane mode and the phone itself doesn't even show stuff like IMEI, mac address anymore.
So now I figure I've probably messed the phone up enough and need help lol. How do I go about reflashing the stock ROM and getting my Nexus back to out of the box condition (Stock ROM and no custom bootloader)?? Any guides or step by step instructions would be very helpful.
Thanks

Did you wipe before flashing roms?

Maybe flashing the KB2 modem would help that but the 9020a came stock with 2.3.3 and not 2.3.1 so that could be it...I'm not sure but that software wasn't meant at all for ours so it could be part of the problem. But if I was you I'd take a look at this thread wich has all the stock software for your phone. Make sure you wipe everything in clockework and then flash the stock rom. http://forum.xda-developers.com/showpost.php?p=13123996&postcount=39
dsixda uploaded the stock backup and the stock recovery, you can read more at that link, good luck hope it helps

You can download the full stock ROM from the link below:
http://goo.gl/8P8vl
Move the zip file to sdcard. Boot into recovery and flash the ROM. It should get you back to stock 2.3.4 ROM, all locked.

edit: well now everything is ok again, wiped data, flashed with CM7 and now it says 2.3.4, go figure.

[Q] Do i need to root before installing a ROM?

Hi Everyone,
Im new here and new at using an android phone with ICS.(used to be an iphone user)
The battery life is just horrible. I want to install the ROM by peter alfonso.
My question is do i need to root before installing a ROM?
If so, how to?
Thanks,
johnnski

no, you dont need to root before installing custom roms. but you do need to unluck your bootloader and flash a custom recovery(like cwm or twrp). when you do flash peters rom, youll get root too. his rom has the superuser binaries.

No, you can just flash clockwork mod recovery through fast boot and then flash a pre rooted rom.
Sorted.
You need to unlock your boot loader alright tho and that will wipe your phone, SD card and everything!! Be warned!!
Open command prompt in windows and type on fastboot OEM unlock and unlock the bootloader.
then fastboot flash recovery xxxxx.img (xxxx.img is the name of the recovery you download, most likely cwm5.0.2.0.img)
You'll find it in the forums. Search for it.

the ease is a plus of owning a nexus device

thanks for all your help guys. i was able to flash alfonso's rom successfully, i think.
in the about phone menu, it says 3.0.8+ [email protected] #1, and there's a super user installed on my phone.
But it's the same look as the original ICS. i thought it would have a different look. I dnt know, lol. sorry newbie.
Did i do this correctly?

Yup.
Sent from my Nexus S using XDA App

If it boots you're in the green
If it's not stable, you may just need to wipe and reflash if you didn't do so. You'll probably just want to do a data/factory reset and format /system.

Ya that all seems fine. Congratulations!
Be careful not to get addicted and become a crackflasher!!
If you feel brave you can try flashing custom kernels or even other roms!
Pete's is as close to stock as you can get really, he just makes stable stock roms and kernels.
Gummynexs a nice rom. Customisable too and cyanogenmod style power menu.
Matr1x v15.0 is a good kernel too. Has all the features available
Just boot into recovery and wipe dalvik cache and flash the kernel.

Thanks guys. although im having issues with synching. it won't sync to twitter or facebook. i do not get background updates.

From unrooted Gingerbread Arc to Ultimate HD rom

Hello,
I'm new to rooting/modding/roms, and I wanna install the awesome Ultimate HD rom on my locked, unrooted Xperia Arc LT15i:
Gingerbread
Android Version: 2.3.4
Build: 4.0.2
I don't know where to start.
The page of the Ultimate HD rom (http://forum.xda-developers.com/showthread.php?t=1920207) says:
- For Unlocked Bootloaders: Flash the Recomnend Kernels; Adv. Stock Kernel
- For Locked Bootloaders: Root your phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=1683957
I don't think I gotta start with this page ^
I wanna unlock the bootloader, that's step 1 I think (via http://forum.xda-developers.com/showthread.php?t=1034087)
But what's the best way to root and make my Arc ready to install the Ultimate HD rom?
I saw some pages like this about rooting:
http://forum.xda-developers.com/showthread.php?t=1133650 & http://forum.xda-developers.com/showthread.php?t=1874801
But I don't know which one is good and which Kernel I gotta use to go from:
Xperia Arc unrooted 2.3.4, 4.0.2
to
rooted, unlocked with the Adv. Stock kernel Ultimate HD rom.
Do I have to install the official ICS update first on my Arc?

first off all you got to unlock the boot loader
follow instructions here
http://forum.xda-developers.com/showthread.php?t=1794800
generally when you unlock the boot loader and install a custom rom, it comes with root so rooting is not required.
when your done reply back to me

Thanks for the info. I was going to unlock the bootloader via the link, but I was wondering:
If I unlock the bootloader, will it delete all my SD data/format SD? I really don't want to lose my SD data

sorry but when you unlock the bootloader, the sd card must be wiped not matter how you do it.
You can take out the sd card when you unlock the bootloader, that might work.

I just unlocked my Arc bootloader without the sd card and it worked!
Now I'm wondering what the next step is before I can install the Ultimate rom ( http://forum.xda-developers.com/showthread.php?t=1920207)
Is it possible to go straight from unlocked Gingerbread to an ICS based rom? Can I now just put the rom zip on my sd and install via CWM?
Or do I need to do something with a Kernel or something first?

nope you need a ics based kernel, usually the rom includes the kernel, but not always, I don't have an arc so I can't recommend what kernel you should use. Anyway, it seems that there is kernel included. You will need this flash tool if you don't have it already
http://androxyde.github.com/index.html?1359317663000
here are the instructions
click the lightning icon,
plug in you device into fastboot mode
click fastboot mode and okay
click select kernel to flash
choose you img file
and reboot
some points to remember.
flashing will wipe your all your app data but won't touch any pictures or movie files; always make a nandriod backup
remember to wipe data/ factory reset before flashing
wiping cache and davik cache won't hurt either
click thanks if helped

yes you can flash any kernel even if your rom is not compatible with it, you just won't be able to boot up if you have a ics kernel and a gingerbread rom, however you will just need to flash the ics rom to get it working.
oh and remember that many kernels require you to flash modules in order to get things like wifi

you can boot the phone normally but you will be able to boot to recovery, press volume down and the power button.
for wifi modlues, just flash it like a rom, but remember to flash it after flashing the rom.

Oh okay. Does the (Arcknight) kernel already incluid CWM? Or do I have to install CWM before flashing? Because when I flash the kernel, it's a factory reset so CWM will be deleted, right?
Also, can I take out the sd card before flashing the kernel to make 100% sure my data wont be lost?

nope the cwm (or twrp) is part of the kernel so doing a factory reset will not delete it.
In fact do you the wiping with cwm.
And yes the kernel already has the cwm.

SGS4G Android 2.2 rec 3e. Do I have to flash kernel and modem before flashing custom?

Yep.. You take a backup, wipe cache,data and dalvik cache. You are ready to flash your custom rom.. But while changing kernels you gotta flash your stock rom+stock kernel then root then flash new kernel then the custom rom.

Appreciate. So I now will backup and wipe everything and then update it with kies mini. And then will ask more about custom stuff, am I doing right?
The problem about SGS4G is that it is WAY TOO MUCH information about it as well as kernels, mods, articles and you are lost because some of them conflicts with other.
P.S. I spent a week for going into Android stuff and Galaxy S.

Well.. If you were talking bout updating your stock rom using kies... I dont see any use of that if you are going to flash a custom rom. Its just mere waste of time.

The guide seems good enough but a bit more complicated that it should be. Anyway here are two tips or info for you. First, whatever you do, have Odin and Stock Firmware ready to flash coz when everything else fails, Odin to the rescue and also flash stock firmware (Rom+kernel) whenever you change kernel as changing kernels without doing so removes root access and you cant apply root update on a custom kernel unless it has pre root access. Second, you dont need any kind of manager to flash firmwares and updates. CWM is a replacement to all. But its all your choice.
