Question, How To Flash Second Time Around??? - myTouch 4G Q&A, Help & Troubleshooting

Hello everyone,
I tried search the answer but only found something in a different phone section and it was not clear.
My question...I have already flashed with the Ice rom and it works fine...when I decide to change roms and flash a NEW one...what are the steps I must do for it to work correctly?
Thanks in advance for any help,
Brian K

If you're staying with the same rom (i.e. upgrading to a newer version of the same rom) - back up, wipe cache/dalvik cache, then flash
If you're changing rom but staying with Sense-based roms - do the same and see if you have any issues. If you do run into issues - wipe data/cache/dalvik cache, reboot.
If you're going from AOSP to Sense or Sense to AOSP - back up, wipe data/cache/dalvik cache, flash.

Its just do the same thing you did the first time. Make sure to do a full wipe and flash

Might be a lil off topic but I think it might be related.....you said 'do the same thing you did the first time'....so i'm guessing first time means the first time i flash a custom rom?? And if so, does that mean for the first time i flash a custom rom should i do a full wipe???
Thanks!

Yes you are correct. The post above mine is way more detailed. You should also do a nandroid backup of the rom you're on now in case you wanna go back.

The best way to move between ROMs is to make a nandroid + Titanium backup. Fully wipe. Flash your new ROM. Carefully re-import settings from Titanium if all seems to be working well. In the event of a failure, roll back to your nandroid copy.

Im really sorry but I still dont understand...I mean I kinda do but dont want to mess up and because of that, I'm trying to have a clear pic in my head.
Example...when you flash for the first time you have to:
flash recovery
wipe data/cach/etc
drop the rom onto the sd card
select the rom from sd card
reboot phone
Do you have to do ALL the same steps again, if you want to try a NEW rom...or no?
If no...what steps do you do differently?
Also...as for the Nandroid backup...do you do this everytime also, or just once?
Again, Im really sorry to be such a newb...but I am trying...I have just about every guide...its just that most guide are not for newbs and alot of times they are outdate. Dont get me wrong I appreciate the guides...I TRULY Do, I just dont want to mess this phone up.
Thanks in advance for any help

Repeat everything as you listed it except for flashing a new recovery (unless moving to/from a Froyo/Gingerbread; as recovery differs between Froyo and GB). I usually only make nandroid backups once I have found a ROM that I like and have it working well. It's a system restore! Then if I want to tinker with the "shiny new ROM" that just came out I can load it up and play with it. If it doesn't work well or at all, just roll back to your faithful fully working nandroid copy you made.

Actually switching between Froyo and GB has been made even easier by the new ClockWorkMod Recovery... TrueBlue's method works amazingly... Find it here http://forum.xda-developers.com/showthread.php?t=944681... Flash it like you would a ROM via CWM... His zip also INCLUDES the STOCK RECOVERY so if you ever want to recalibrate the battery you can do so by going into Rom Manager and selecting 2.5.1.4 as your recovery, when done just switch back by selecting 3.0.0.5 and that will load up 3.0.0.6..
To answer OP's Question...
Step 1) NANDroid backup (Backup and Restore > Backup > press trackball)
Step 2) wipe data/cache/dalvik (I always do each of them twice for safe measures); Like someone here already said, if upgrading to a new version of THE SAME ROM BUT ITS BEEN UPDATED, just wipe CACHE AND DALVIK. Otherwise, wipe all 3.
Step 3) Install zip from sdcard > choose zip from sdcard > select the ROM you want to install.
P.S. FYI I WOULD DO THIS FIRST!!!!! For flashing TrueBlue's 3.0.0.6 to be able to flash both froyo and gingerbread roms without changing the recovery each time (which is a pain in the ass btw) FOLLOW STEP 3 EXACTLY. The only difference is you will choose GlacierRecovery_to_RomManager.zip instead of whatever Rom you want. Reboot, go into RomManager, scroll to the bottom and select All ClockWorkMod Recoveries, choose 3.0.0.5 and it should say successfully flashed. Reboot into recovery and make sure at the bottom it says CWM 3.0.0.6. If it does, congrats, if not, reboot and reflash it, and continue to do this until you see CWM 3.0.0.6 at the bottom of the recovery screen.
PM me if you can't get it to work and want some more help with anything!

Hello,
I want to say it again, that the people in the Android forums are so much more helpful then back when I had a iphone and needed help. The people over in the iphone forums would sometomes help, but most of all, they would be rude.
Android forum techs are the BEST!
As for the Nandroid backup...this part also is a bit confusing, cause a few guides/videos show them doing the nandroid after they do the 3 wipes. However, I thought it made sense to do it first like you said.
Last night at around 4am I flashed CM7 with no problem and it is truly amazing. I am started to make sense just a little bit of all this but right now...I still cant wrap my head around the whole flashing recovery process.
Please understand I.m not just asking for answers, I am also reading as much as possible...I am making an effort.
Thanks so much everyone,
Brian K

No problem. If you have any questions I'd be glad to answer them for you or direct you in the direction for your answer. Just pm me like I said.
Just continue to read read read.. That's why I did and this is the first phone I've rooted or done anything with and I've become knowledgeable with some of the easier concepts and I'm trying to learn more complicated concepts as I go along.. Everyone had to start somewhere, and most of us here on xda realize this which is why we are so happy to help as long as these questions aren't asked and answered 4000 times.
P.S. Where ever you read/watched to wipe before NANDroiding I would advise to not go back to that because that is COMPLETELY the wrong thing to do!!

Amac1222...just to be clear...your saying to do a Nandroid backup before wiping ANYTHING...yes?
Thanks again for everything,

Yes, even when updating your rom, you can always move the nandroid off your sd to an external hd. Or you can delete them as you move up updates, (i.e. Build 41 to 42 to 43 delete 41 once you know 42 is good to backup to if needed). When I flash kernels I tend to not nandroid each time although I should. As a super noob I would and I used to until you are comfortable.
The basic thing is you always want something to fall back on in case you get stick in a boot loop or stuck on the mytouch screen.

Tips for my newly rooted Sprint Hero phone?

Hey! I'm a little new to the rooting and such on a
Android phone but yesterday I rooted and
installed Fresh Rom 1.1 on my Sprint Hero, and I
was wondering where is a good website to
download themes for this Rom? And if there is
any tips/cool things/ ect. ect. that you can do
with a rooted phone tell me please. Cause I'm a
noob as I said. . Thanks
Sent from my HERO200 using the XDA mobile application powered by Tapatalk
best advice I can give is read the how to WIKI's BEFORE doing anything else. ALWAYS read the first post of any rom that you want to try then re-read it just to make sure you understand if there are any problems and or fixes. also ALWAYS make a nandroid BEFORE you change anything with your phone. after all that just watch the boards and check out all the cool stuff.
edit: and I forgot the search button is in the upper right of the screen and will save you a lot of grief from the flamers
Thanks dood.
I just rooted mine, too and all I can say is read read read read. Try different things you're cmfortable with, and just enjoy how much better it is rooted.

Do you nandroid after changing anything? I did it as soon as I got root last night, but now I have loaded a custom rom and am thinking about adding mods and themes... should I nandroid every time I put a new rom on or is the very first nandroid sufficient?

Did you use fresh kitchen? I would make sure your recovery console is 1.6.2 as you can pick which nandroid you want to restore. Just nandroid before flashing a ROM or a Theme, so you can revert back to what you had before if something is not working.
The first nandroid you have should be the one with the stock ROM+root. I would take this and save it on your computer so you always have it.
I'd say that you should make a backup copy every time you change anything significant, or anything you do while booting in recovery.
Its probably not necessary to do it as often as I do, but I figure a few extra minutes of waiting for it to finish is worth not having the frustration of not being able to revert to a past state if something screwy happens.

I used the 'static wiki page how-to' for getting everything done, I think they supplied a link to this one: recovery-RA-heroc-v1.5.2.img, which I guess is outdated... I'll look for the 1.6.2 version instead. You are correct, my first nandroid is the stock + root and I did save this to my computer, but I haven't nandroided since then because I didn't think I needed to. I think I will nandroid again now that I am on 2.1 ROM and then nandroid whenever I mess around with the recovery / new ROMS. Thanks guys.
For the 1.6.2, do I just repeat the sticky how-to for installing this recovery? I don't want to mess anything up since I already have the 1.5.2 recovery installed. Will it just overwrite?

I dont get it

Ok I dont get what I am doing wrong when I flash a custom rom. Its seems the only rom I can flash is the original one toast had with the Super user permission. When i try to flash other roms they just loop on the boot screen. I dont know what I am doing wrong I wipe the cache like it says to do.
Am I missing a step or what someone anyone let me know.
this happens to alot of people. you are not alone!
Wiped cache and user data?
I have tried that I have wiped the first three options on the wipe screen and still loops with every rom but one
Clockwork recovery doesn't wipe dalvik properly from what I hear and that would cause a loo.
I have tried clockwork and and just rebooted my phone into recovery the manual way and that still doesn't do it.
Please put the topic of the thread in the Title. That's what it is for.
Question, you said the Rom that toast first supplied. Have you done nand unlock? Most roms now require the second part to obtain full root. Fresh, damage, etc all require both steps of toasts root.
Wipe cache and data...i use tom manager to get in recovery mode then I wipe everything from there..i don't use rom recovery to wipe...just to get in recovery...

Yeah did all that too. idk what to do maybe blow up and start over.
Starting fresh does work wonders sometimes. Do you have a custom recovery flashed to the partition? And have you also double checked to make sure you can successfully remount the system? (just to ensure your name is unlocked, not entirely sure what the problem could be)
So, how do I start from stratch??
Hmmm. Well you could flash a stock Rom with no root and start back at toast's part 1 of rooting..... but I am quite sure you could just repeat part 2 of toasts rooting method. thats what i'd do. Start at part two and redo all of that. Keep that recovery flashed, then do all the wiping and just drop a Rom on your card and install it through reboot recovery command.
Just an update I did the rootinng over this time i used the Simple Root .2. Thats the 1 2 3 click method and that worked for me so now i can flash roms thanks guys

Thanks, do you guys recommend any roms?
thats like asking someone what kind of pants they like
lol. best bet is to go to the dev forum and see which ones you like. Try one try em all
True I am stuck on one for now I really like the Fresh 0.5.3. Its trimmed down and seems fast. There where a couple out there that seemed to bogged down with all the graphics and apps they left on there.

For Those Just Getting Root!!

Here's what you need to do!!
First, make a NANDROID BACKUP of your stock, rooted setup.
TRUST ME on this, you'll use it to do things like GPS fixes, PRL updates etc.
Use Amon Ra. DON'T use ROM Manger. Backup everything except Cache.
On that Nandroid you'll want Titanium Back Up, GPS Status and updated Maps installed.
For ROMS, if it were me, and I knew what I did now, I would start with the Sense ROMS, since you're used to that, just to see what a GOOD Sense ROM feels like.
Always wipe everything in Amon Ra, except the SD Card itself (Although people will argue with me that it's not necessary). Trust me on this, too, ok?? Just do a full wipe and erase any doubts when you have issues that it was wipe related.
Then, once you realize that Sense is boring, give CM 7 a shot, or better yet, MIUI!
AND READ READ READ READ READ as much as you can before you do dumb things.
And conratz!! It's about time!
Exactly what i was looking for, thanks! :]
Thanks! I was looking for this as well, in the process of creating a complete backup with amon ra. Was kinda wondering what I should flash tho, sense bores me
I've had them all, and I'm locked in MIUI now
So you're saying backup the following?
Boot
System
Data
Recovery
Wimax
Sd-ext
.andriod-secure
that's everything but cache - why not cache?
Also, what's a good rom if Battery life is most important... one that undervolts?
Cache is just temp files. You don't need them, but everything else, yes.
You only need boot data system and Wimax. I reccomend using a format all zip between rom flashes.

This thread isn't the place for help rooting. Plenty of others, or post in Q&A.
Key thing is to backup, at least, your WIMAX. It's almost impossible to lose your WIMAX partition anymore, but better be safe than sorry.
You could nandroid everything.. but it's kind of pointless. There are RUUs out to flash back to stock, and zips you can flash too. Mainly just ease of use since the nandroid will already be on your SDcard.
Also as hipkat says, do yourself a favor and don't use ROM Manager. Don't use CWM recovery either (well, it's up to you but it's pretty old now). Amon_RA is the mature stable recovery, and the TeamWin recovery is the new kid on the block... functional but not as robust yet.
Sorry about that lad, and yeah I will backup everything if I can get the damn thing to work
It looks like quite a few people are having issues. Just hang tight and see if there is a fix.
Also check the guide over in the development section to make sure you got the step %100.
Well, I just got it!, uninstalled HTC sync and drivers, reinstalled the HTC drivers and ran the .exe zerging root passed!
Said no to Clockwork and installed Amon RA from fastboot, then flashed SU and now I'm ready to backup

Thanks for this defiantly useful...time to start flashing
Thanks for the reminder, I am new to rooting this phone. (Not new to rooting, had HTC phones from G1 and MT3G, in those I am GTG.) Installed CM7 latest one. But I am interested in MIUI ones and the videos looks awesome!!!
MIUI has come a long way form when I tried it a few months ago...
Sick. Thanks for the heads up. Also, I appreciate the To-Do List. This is my first venture into rooting, so as you can imagine, it all seems a bit overwhelming at first.

Reboot into CWR (both volume buttons held in) while booting until you see “Vibrant'
Once there, go to Backup and run that. Should take about 5 minutes, maybe more.
If all hell breaks loose, this is a snapshot of your phone at that point... it's important to do this before flashing a new ROM!
I'm sure it's something stupid on my side BUT, all the options i have after booting in CWR are(blue): reboot system now, reinstall packages, delete all user data, delete cache data, format internal sd-card.
I decided NOT to touch any of those now since i cant find the Backup option on there, so i just rebooted my phone. Please guide me with a link or something. Thanks. I don't want to rush things.

thats the cwm recovery, i dont think you backup from there.
you backup using the app, and nandroid I think.
also make sure to save the backup onto your computer also!
also, there is a special folder, i forget which folder it is. it must be backed up separately i think. It contains your phones imei and other information, without it your radio and phone will not make calls. back that up. I forget what its called. If you loose that, you lost it for good and your phone is junk

That's actually incorrect. What you described is still the stock recovery menu. Cwm recovery has more options, and the text will either be green or red, depending on whether you have the ext4 (voodoo) lagfix applied.
If you have the correct CWM update.zip file on the root of your internal sd, then boot into stock recovery and select "reinstall packages." You'll be thrown back into stock recovery, whereupon you select reinstall packages a second time. That second one will put you in CWM recovery.
And to clarify, you CAN restore/backup from CWM (as well as many other things...maybe read up on that). Just remember that a backup does not include your kernel, in case you bounce between 2.1, 2.2, and 2.3 roms.
Hope that helps...good luck.

You're thinking of EFS. I don't believe you can back that up through recovery. There is a different procedure for that which I can't recall off the top of my head.
Don't forget, after flashing you should wipe cache, wipe dalvik cache, and fix permissions. All are options in the recovery.

Help with wipe-rom-kernal for first time, If have donate button I can donate cpl$

Im not rich or I would have got a newer version tablet by now, but if anyone who helps has a donate button I have no issue donating a couple dollars to the person who helps me get this done, Thanks. Or just a couple dollar PP gift. better than nothing I guess.
I just want to be sure I dont mess anything up here. I have a nexus 7 wifi model.
I used NRT to unlock and root and all seems fine. Am I correct in this:
I use nandroid backup to backup first
Put ROM file on device (where do I put it?)
Wipe (is this done via nexus root toolkit or is ok do do in the custom recovery?)
Then what, boot into recovery and find the ROM and install it via recovery install button?
Then do I do the same with a kernal? Where do I put it?
Then done?
I know there are guides around but for a complete newbie I need to be sure cause I dont always see a complete fully explained step by step. Just like when I was stock not getting SU to work after rooting via nrt, I did read to flash SuperSU.zip, but had no idea how, then when I found the file and thought maybe install from recovery meant same as flash, I didnt know the message about messing the device up was normal so I was afraid at first.
THANKS to any replies,
Been unsure for days now trying to make sure my ducks are in a row before i commit to a ROM/Kernal. I want to CPU control for both under and overclocking etc. Mainly overclock just a little. I must say I love root already, got stuff to work I couldn't before
1. Create nandroid- there's a free app called something like nandroid on line - very simple to use
1a. I'd also recommend backing up with titanium backup app. It means you can keep your app data (e.g. game progress) when switching between ROMs, unlike a nandroid which is just a backup of your device as a restorable image
2. Put ROM file on device - ROM will be a .zip file, out it wherever you want, as long as you remember where it is
3. Put kernel anywhere on device - easiest to find a kernel with .zip format (recommend M-kernel)
4. Wipe - from custom recovery
5. Hit install in your custom recovery, I always flash kernel and then ROM, but I don't think it really matters
Install from recovery and flash are the same thing.
I'd recommend only flashing ROM or kernel and sticking with that set up for a few days, then flashing the other desired element. That way, if anything goes wrong then it's easier to pinpoint.
Good luck!!

Actually that completely matters. Flashing a kernel before rom is worthless because the rom contains a kernel that will replace whatever you have just flashed.
If you want to run a custom kernel on a rom it is recommended to boot into the rom first before flashing the kernel.

If I just want root access and overclock should i just flash kernal and forget a rom?
can i revert back to stock kernal if need to? ask cause need to find a kernal that has V4L enabled for a usb camera app i use currently to use an inspection camera via usb on my tablet. I guess i need to read what various roms and kernals add. do i need to do both. Hard to know what to pick out of them, lol.
Thanks for advice.
Anyone know of a list to show ROMs with V4L enabled? None seem to mention it?
I have read and see different suggestions around on various sites. What all do I wipe? I have read cache, dalvik cache, plus other stuff. What all must I wipe before flashing a rom or kernel? I did a nandroid backup already.
PirateGhost, Ill donate a couple dollars if you help, thanks.
Thanks.
When going from one rom to a different one all you need to do in custom recovery is select factory reset.
This wipes out your currently installed apps, their settings, but doesn't touch your 'sdcard'
Wiping dalvik is pointless as it's automatically handled in the rom process, and cache is wiped in factory reset.
When switching kernels follow the instructions provided by the dev. If no instructions are provided, it's safe to assume you just flash without wiping anything.
When doing this, I'd recommend titanium backup too. When you do a factory reset, all apps are lost, but some data is kept (not sure on the details). Basically Titanium allows you to restore all your apps with data when you change ROMs.

I have not put any customs ROM(s) on yet, so is it the same still? All I have done so far is unlock/root with custom recovery and nandroid backup....

Yeah I backed up the one app I needed to via TB, I just recently unlocked and rooted so lost most app data anyway and have only added one back so far. Thanks.

No data is kept except what's on the sdcard. Mostly only game saves and some basic stuff. Apps databases are wiped during factory reset.
