[Q] Newb question: How do you flash custom ROMS

I rooted my EVO running stock Froyo last night with Unrevoked 3.2. It worked flawlessly and phone is experiencing no problems. Now i'm all excited to run the custom ROMS but kind of confused as how the flashing of the custom ROMS works. Do I have to wipe out the entire contents of my SD card everytime I want to run a custom ROM? I only have the 8gig card. I was under the assumption that I could save my current stock setup and download and flash into a custom ROM and revert back to the stock rooted setup when I wanted. I downloaded a program called ROM Manager v2.0.2.6 but unsure how to use it. Looks like a 1-click solution to loading custom ROMs but I dont want it to wipe out my phone. Can someone please help me to understand the steps to take to load a custom ROM? I was thinking of trying out Fresh or something similar which still has HTC Sense in it. Feel free to message me on here. Thanks in advance.....

No.
I'm not sure about using ROM manager, perhaps somebody else can help with that.
The process is simple...
Connect your EVO to your PC and enable disk drive.
Transfer the ROM zip to the root of your sd card (if your computer mounts as drive F: ... just transfer to F:\)
Eject/disable disk drive
Boot into recovery (turn device off, hold volume down and power button at same time until you see your hboot screen, choose recovery)
Perform a nandroid backup (just in case you need to get back to where you are)
Perform wipe
Use recovery option to flash zip from sdcard
Select the ROM zip
Those are the quick and dirty instructions, I'm a newb with this stuff, I've had my EVO for 2 weeks and I've not had a single problem. I had CM6 on it and I just flashed Fresh 3.2 to test that out and test 4G this weekend.

I would advise doing a Nandroid backup of your current setup. Then go the development section and choose a rom that suits you. Each developer normally will tell you how to go about flashing there rom.
Basically you would need to go into recovery and choose the flash from zip...

ok first no you dont have to erase your sd card every time you flash a rom.
you should however do a factory dalvik and cache wipe. this will erase all settings yuo previously had and will uninstall all apps.
to combat this you can use programs like Titanium back up to back up all your apps. (system settings are not recommended to be blind restored as they can cause issues between roms)
You can also make a back up of your stock rom you have now to do this through rom manager simply make sure you have the latest clockwork recovery flashed (very top button in rom manager) then go down to where it says back up rom click it and it will do the rest. This is recommended before you do anything.
once you ahve your nand back up (the back up through rom manager) and have your apps backed up through something like titanium back up. place the rom yuo want to flash on your sd card and follow these steps.
boot into recovery (either through rom manager or by powering down the phone and then holding vol down and power until it launches the boot loader and select recovery)
select wipe data/factory reset
select wipe cache partition
Select install zip from sd
select choose zip rom sd
scroll to and select the rom you moved to the sd card
select yes and let it do its thing once done select reboot phone.
It will take a little extra time the first time it boots up vs normal jsut let it sit and it should after a while boot into the custom rom.

Thanks everyone! I'm running titanium backup at the moment and backing up the entire system. I had ROM Manager do a backup of my stock ROM last night, so I think i'm good. ROM Manager also downloads ROMs for me and sets them to load at boot up. Most of the ROMS suggest doing a full wipe?

a full wipe jsut means factory/data cache and dalvik which is basically wiping all info on the phone itself. the sd card however doesnt need to be wiped

i installed baked1.7 and all loaded smoothly. I'm assuming I now have to re-download titanium backup to restore my apps and all?
Also, i'm finding no info on how to load the wimax update and the htc radio update files and the custom kernels for baked1.7

Load those updates onto the root of your sd card. Get quickboot from the market to easily boot into recovery mode. Or you can power off, then hold vol down while powering on to get into bootloader and select recovery. Flash zip file and select those files. Reboot and your wimax/radio should be updated.

[Q] How do i do and nadroid back and restore?

Kinda noob question but can someone post screens on how to backup and restore a nadroid backup??
Thanks
Title meant to say: Backup not back

If you're not rooted then you can't do a Nandroid. When you use a custom recovery image like Clockwork Mod you have the option to do a backup (refered to as a 'Nandroid').

yea i know i am planning on rooting tonight just want to know how just incase anything goes wrong

Ah right!!
Once you've run unrEVOked it will install Clockwork Mod as your recovery image. In there is the backup and restore menu which is where you perform a 'nandroid'. It basically copies your system onto your SD card so you can revert back to it should a new ROM flash go wrong/not be to your liking...it's easy really!
Getting to Clockwork Mod is the same as getting into normal recovery - turn the phone on whilst holding down the volume down button, select 'Recovery' from the menu and there you go!

Or after getting clockwork mod on your phone you cab download an app called Rom manager this has a menu with options one is back up or restore your Rom.
Sent from my HTC Desire using XDA App

Thanks, got another question, i would like to flash opendesire how would i now go about doing this ?? i am rooted now

Boot into Clockwork Mod, select 'install update from SD card' and choose to select from the SD card and select the OpenDesire ZIP file. You'll also have flash a radio that's compatible with the ROM (which is done the same way)

do i need to wipe data/factory reset??
Thanks

I'd say yes as you're going from a Sense ROM to non-Sense - better to be safe than sorry

and do i now click apply sdcard:update.zip or install zip from sdcard
Thanks!

Install zip from sdcard.
Highlight and select the zip containing whatever you want to flash (the ROM or the Radio)

I did do this a while back...

WoW!! All done now on OpenDesire Thanks guys When i partition my SD card to ext or whatever, does the cache and stuff go to my SD card automatically?
Thanks

[Q] Many questions (CWM, ROMs)

Hi,
I'm new here and I'd like to install a new ROM on my Gio but I want to make sure I know what I'm doing before trying something and bricking my phone. :angel:
ClockWorkMod
I installed CWM v5.2.0.6 (followed the instructions here). Is this ok, or do I need to install v5.0.2.7? And if I do need a newer version, is there a way to get an update or do I have to follow the same steps as before?
1.Download the CWM 5.0 v2 and copy to the Root (not in any folder) of your SD card
2. Put your phone in recovery Mode(press: Home button + Power button toghether)
3. In recovery mode, select the downloaded file from SD-card(Use Volume keys to navigate and home button for enter).
4. Search for the root gb updated.zip file on your SD-card
5. Run the update
6. Reboot
Click to expand...
Click to collapse
I tried creating a backup with the CWM version I have, but I get this error: "Can't mount /system".
CWM does create a folder in sdcard/ clockworkmod/ backup/ date, but it only contains the following files:
recovery.img and boot.img.
However, this post says I should actually have more files in the backup folder:
.android_secure.vfat.tar ,boot.img , cache.ext4.tar , data.ext4.tar , nandroid.md5 , recovery.img, system.ext4.tar.
Is this because of my CWM version? Or maybe because I still have the operating system that came with my device (+updates)?
What I really want to know is: can I rely on this backup, will it work?
ROMs
I want to install CM10.1.5 from here, but I have many questions and I don't really know where to look for answers. (Sorry, I really am a complete noob.)
What's the difference between androidarmv6 jenkins build and mardon build? And what's the difference between the 3 versions? Can I just install the Version with CM-Superuser and not worry about it?
Should the updates be installed via CWM - apply update from SDcard? What about the additions - CWM --> install zip from SDcard?
How can I install extras if they are "not CWM flashable"?
What happens to my apps when I install a new ROM? Do I have to install them all again? Is all data lost? Or will they all be restored from my google account and the SD card or something like that?
Finally, how can I use the ext2 partition in my SDcard to install apps? Is this function included in the ROM? Or do I need to install something else? a2sd darktremor? If yes, how (I find the instructions here confusing and overwhelming, and the post is old, so probably outdated)? Or should I use the "Link2SD" addition to the ROM?
I'm sorry for asking so much, but I'm feeling kind of lost.
Thanks in advance.

Anyone?
I've continued trying to figure things out when I have time. I'll post what I find in this thread, in case someone else comes here looking for answers to similar doubts/problems.
In trying to understand what's going on with ClockWorkMod Recovery, I found this very useful link:
wwwDOTtechbiiDOTcom / cwm-recovery-cant-mount-system-error-solution-how-to/
(sorry for the DOTs and spaces, can't post outside links yet)
CWM Recovery – Can’t Mount System Error Solution [How To]
(...)
The error is an expected one and happens generally when you are trying to backup a stock ROM using the clock work mod recovery. Please, note that you can’t do a completed nandroid backup of a stock firmwares. So, just install any custom ROM and then you can backup and restore anytime.
Click to expand...
Click to collapse
If I understood correctly, the best (only?) way to return to stock ROM is to install Odin or similar firmware flashing tool and to get the stock firmware from sites like sammobile.com and sampro.pl. However, it also says that not all firmwares might be available and I haven't looked more into it all of this yet.

Did you root your phone yet?
That should solve the problem from the can't mount system, data, etc

Yes, I used the instructions there to root my phone and install CWM (v5.0.2.6), but that thread is 2 years old, so I'm afraid it won't be up to date in relation to certain things. For example, I did create an ext2 partition on my SD card using those instructions, but I found an easier way to move apps from my phone to the SDcard (using the link2SD app, available on Google Play). The information about ROMs is also not up to date.

If you want to install a custom rom just
-wipe data factory reset
-wipe cache partition
-advance>wipe dalvik cache
-install zip from sdcard
-reboot
NOTE: the zip is the rom

Thank you.
My main concern at the moment is how to restore my original ROM if something should go wrong, though. I've found some interesting information in this thread but I've been busy this week and I'll need to go back and read it all with more attention before I try something.

Guide & Mod : Telcast G18 mini 3G tablet [CWM Recovery][Stock Firmware][Partition Data]
Hello,
I got myself a nice 7.9 inch Android 4.2.2 Tablet [16Gb].
This is a new tablet so no rom/mod information about it so I decided to put few things together.
I messed up my Modem/Radio trying to make CMW mod recovery but got lucky and found a Chinese forum with a stock rom.
That gave me confidence to mod like hell till I got myself a working CWM Recovery
Youtube Video of tablet
http://www.youtube.com/watch?v=Ybz6yymWM7I&feature=c4-overview&list=UUUAnm9j-J2x3_nDDDxO2nlQ
Warning! use this guide at your own risk.
Root Guide:
Just download Framaroot apk and run it! It will ask you to reboot and that’s it...You are Rooted!.
CWM Mod Recovery Guide:
Download the G18mini Recovery and flash with MobileUncle.apk
Place the .img in the root of SD then launch the app and click update recovery. Tablet will then reboot into CWM . Do a full nandroid back up!! You will need it in the future or if you want to partition.
Or Flash with SP Flash tool (can find easily on XDA and included in full firmware DL)
Partition /data for more storage Guide:
This tablet only has 1GB for apps which is lame!
Make sure you have Nandroid Backup before doing this and copy the backup to external SD (required)!!! or use Rom manager to backup to external SD!
Install meteos-mtk6589-rom-edit-8gb-16gb-en APK
Run it and click the 4GB and follow the instructions and reboot into recovery.
Wipe/reset then do an Nandroid restore from external SD
It will show failed to restore SDCARD but don’t worry, boot into the tablet and format/erase internal (Flash storage)
Turn off the tablet then hold volume up and power to boot recovery. Do a full nandroid restore again from external SD…DONE!
You will now have 3.9GB for apps and 9.7GB internal storage!
Restore to Factory:
Stock Firmware DL has a PDF in chinese but screenshots should be enough to restore the tablet top factory stock (it uses SP Flash)

messed up but found the original firmware
Hello guys, I'm new at breaking into Android devices, and it seems I messed up when trying to follow this Guide and Mod.
Somehow I didn't do this step:
-----------
CWM Mod Recovery Guide:
Download the G18mini Recovery and flash with MobileUncle.apk
Place the .img in the root of SD then launch the app and click update recovery. Tablet will then reboot into CWM . Do a full nandroid back up!! You will need it in the future or if you want to partition.
Or Flash with SP Flash tool (can find easily on XDA and included in full firmware DL)
-------------
After root i performed the partition. And whiped data. So it seems that all data is erased, I manage to come to the recovery menu. When i afterwards manually copied the G18mini Recovery.img file to the root of my sd-card, and tried to boot find the update, it says no SD card can be found...
one option it gave was to adb sideload data into the tablet. Tried that, but did not know what data i should sideload into it. It seems it need a file.zip.
Somebody asked for the firmware, i found the original firmware from modecom dot eu -> support -> download -> tablets
I tried also to istall that, but did not succeed. It seems the drivers won't load into my windows 8.1 computer.
Any suggestion how to proceed? Can i get the original firmware installed by using Android SDK Manager? I hope I'll be able to save the tablet...

Did you solve it?

Me cannot restore from sdcard either. Does it mean that one should erase sdcard while in recovery mode? I did that, but the externat sd card won't still work.
