Close please>?

if this is the wrong place for this SORRY IN ADVANCE
ok so after rooting my shift i followed all the steps got the recovery on there and downloaded a ROM and wiped everything and when the rom flashed it said error 7 instalation aborted so i hit reboot system now just to see what would happen because i did wipe everything so i was expecting to be stuck at the boot img..no problem was just playing around but the thing actually booted in a rom that looks 100% stock....what happened
even tho the ROM looks 100% stock it is def not i have adfree and esfile explorer added to app drawer now if its gonna flash the rom anyways why does cw 2.5.1 tell me its a no go with a stauts 7 i have even formatted my card to wipe it 100% and the same thing happens>?

when you "wipe" you're not wiping the rom. The data, cache etc yes. Only a rom install overwrites a prior rom. unless you format the phone.

People that flashed the base steel posted had similiar issues. E.G. if you were on cm6 and wiped, then flashed the base, you'd boot into a fresh cm6. The partitions were setup wrong, I believe.

I just rooted for the first time yesterday so I'm fairly new to all this... is it common practice to wipe cahce/dalvik prior to flashing any ROM?
I've gone back and forth from the stock ROM to another custom Sense ROM without wiping and no issues. Is it only advised if something goes wrong? Also, is there an issue with just going into recovery and wiping cache when NOT flashing a new ROM (just rebooting to the same one I'm using)? Thanks for the help.

Its good practice to always wipe. You may get by without it a few flashes. But eventually you'll be haunted by force closes, boot loops, etc.
Personally when I flash a new rom after the data, cache and dalvik wipes I format my boot, system, data and cache partitions manually via the mounts menu.
From experience, to truly see changes in rom updates or properly enjoy an entirely different one, this eliminates most problems before they ever manifest.

Can't run Sense based ROMs

My wife and I both have MyTouch 4Gs and both of our phones exhibit this problem. Whenever I load a Sense based ROM both phones reboot without warning. The last time I had a Sense based ROM on her phone it would continuously reboot when plugged in to the charger. I loaded a Sense based ROM on my phone last night to try out and it would reboot every few minutes. I've probably tried six or seven different Sense based ROMs and the rebooting issue always happens. Both of our phones are currently running a CM7 based ROM and working fine. Anyone else see the same issue?

And/or are you flashing anithing else right after flashing the rom? If you are, don't. Just flash the from and reboot. Also, make sure you're found a full complete wipe. Wiping data, cache and dalvik before flashing.

That problem can also be caused by the phone being overclocked a little too much. Try changing speed and voltage to match stock.

You need to do a complete factory restore via the recovery image. the /system is the most important part to make sure is wiped. And from that statement you're not doing that.

@EQJUNKIE829 hit the nail on the head. Just flashing a new OS isn't wiping the old one. You need to do a nandroid backup of your current OS, then do a complete factory reset. It WILL NOT wipe the recovery image or the hBoot. Then flash the new OS.

No matter how many threads I say to wipe the bloody system partition in, there is always this problem. Its frustrating.
Help my phone acts weird.
Did you do a full wipe?
Yes
Are you sure? You wiped the system partition?
Umm, I dunno. I think so.
:faceplam: Wipe system, data, cache and dalvik cache and reflash.
That fixed it. Thanks!

Clean wipe before install and check md5um

Starting from scratch.

Ok folks,
I'm having a hell of a time with my phone.
No matter what rom I flash, seems to have issues from lockups to reboot.
I have tried every kind of wipe in CWM, inluding making sure I have the latest version of CWM and modem, same.
Is there a way to TOTALLY wipe everything on the phone and go back to true factory default, even as far as the phone number programming? Like it was when it came from Splint?
(Yes, I'd then want to unlock with Odin and put a new ROM).
Thanks much!

Yes it will put the phone back to when you took it out of the box..I think he means that if you have any files that you downloaded to the internal storage ie pics,music,contacts things like that they won't be touched.
Just download the Odin file and the Sprint file which is the stock software the phone came with and use is procedure.
Just to worn you The Sprint file is large and will take awhile to download to your comp

Get the full mf9 tar.md5. Remove sd card. Flash with pc Odin. After phone boots up to home screen and settles down, don't set up anything. Go into settings, accounts, backup, then do full factory reset with wipe of internal storage. After it reboots and settles down again, you're completely back to stock. No need to wipe your phone number and associated settings. If it were me, I'd stay away from custom roms if they're giving you nothing but problems.

That's what I did just rooted the mf9 and got rid of all the bloat.No problems to speak of..

Not to be unappreciative, but, w/o a reset all the data was still there.
Which makes me nervous wondering if there is some crap left over.
Yes, I realize a wipe will get rid of the apps but I want to make sure I'm truly starting from point 0.

So if you are on MF9 good luck with going back to stock everything. Because the methods mentioned above don't get rid of the MF9 Firmware just the Build. Also You have use triangle away which only works on MDC and MDL to get to fully clean stock. Everything mentioned in this thread will not do what you want if you are wanting it out of the box like new condition.

first thing I would say is, do odin to your new firmware, and the out the system, without installing or restore apps, and app data, see if everything is working fine, sometimes by restoring older app data you might run into some problems..

What do you mean with "do odin and the out of the system"?

Use ODIN.. what I mean to say is do the full firmware via ODIN,
And use it like that, a fresh install, see if everything is working well, you should have no problems.
Then see when the lag starts if you are restoring your apps with data.

you didn't answer to my question earlier. Did you do a full wipe ?
by default, any flashing of firmware won't wipe your device. It has been suggested by most ppl here, and other forums website, that if you face any trouble with the new firmware, always do a full wipe. It helps most of the time with most of the funny funny issue.

no i didnt do a wipe as i got it OTA not through odin

are the 2 of you the same person ? LOL
@drashrafsabry : very simple, if you done the OTA already, now try to do full wipe (I assume you are not rooted)
1st of all, you will need to backup your contact (if you keep on your device), you can do by exporting it to sd card, or merge with google/samsung account.
2nd thing you need to backup your sms (if you still need to keep it).
3rd and most important : full wipe from stock recovery, it will delete the entire internal storage. So, if you have any data (photo, movie, songs, etc) which you keep it inside internal storage, you must copy first to your sd card / or your PC / laptop (somewhere else other than internal storage.
Once you finish with all that backup, you may shutdown your device (wait until vibrate to make sure it shutdown completely).
Once it is shutdown, press the 3 combos (vol up + home + power) to go into recovery.
Once inside recovery, choose wipe data, and after finish choose wipe cache.
when it is finish, reboot.
PS : you will need to re setup your initial setup after that.
Good luck.

Need FULL WIPE

Hi. I have the Galaxy S5. I updated it to the latest firmware which screwed my device. It is overheating for nothing. Many time I flashed back to stock roms but nothing's changed. I suspect there is still left in the device from the latest firmware "virus". I want to do full wipe. I heard wipe cache and wipe partition only delete user's data. Isn't there a way to start from FULL scratch? Thanks.

If you reflash your device and you do a full wipe from recovery, then your phones software should be like brand new. It might be a hardware issue.

No it doesn't delete everything. Because when I downgrade to KitKat from Lollipop, the power off battery animation is still from Lollipop, just for an example. That's why there is TWRP recovery (just discovered it) which allow you to delete the Data, Cache, System and Preload partitions of your internal memory. Since I am not rooted "yet", I am looking for an alternative for it. Anyone?

Why should TWRP or CMW recovery separately add System and Preload partitions options if not for a reason?

I think I have to root and lose my warranty. Damn you Samsung...

Because no OEM in their right mind is going to give people a device with a recovery capable of wiping the system partition, that's completely inane.

Yeah? What makes you think it is completely insane or insecure to do this? Are you saying TWRP developers (and others who put that choice to their recoveries) are stupid? Do you think they put that option just for hobby?

Jesus Christ, I'm saying giving that option to the average customer is stupid because they would delete their system partition, brick their phones and then blame the makers of the phone. Why do you think you break your warranty when you root or install custom software like TWRP?

Here is what I do so far:
Revert back to factory settings
Delete old app infos via Google
Wipe cache and full wipe via stock recovery
Flash full ROM via Odin
Root and custom recovery to wipe system, cache, dalvik, boot, simply anything can be erased
Yet nothing helped. Using KitKat 4.4.2 now and still have Lollipop animations that indicates there are datas AFTER all of those wipes. I'm absolutely furious!!!

Will my device be okay if I flash another country's stock ROM?

I can't understand this situation really: Why even after all those wipes I still end up with the Lollipop battery animation while I'm using KitKat (even very early builds)? Let me be clear: I am no against the Lollipop battery animation but it confirms some data are erase proof. And because of it, I think there is no way to get back the phone to its very roots. Is there a logical explanation for this or shall I stop trying by calling it Android's stupidity?
