ColorOS 7.1's Recovery Mode - OPPO A72 Questions & Answers

Is terrible. Store anything important on an sdcard. I've had it for a month and it went into a bootloop then the recovery. It says you can save your data by connecting to wifi to download the ROM and reinstall. except then it says you already have the latest version and no download for you. No MTP so an sdcard and finding your ROM on their site is the only fix. Mine was in the Australian section, I'm in New Zealand, oh well it worked. But it didn't work without formatting data. Wiping it and keeping internal storage was an option but didn't achieve anything. Unsure what caused the issue in the first place.

It also has no file manager even though it was protected by my screen unlock code so you can't move anything from internal to SD. No ADB either.

[Q] can't root, can't delete anything

I just bought a used vibrant... sadly it has a huge problem.
Problem consists of:
1.Can't remove previous user gmail account
2. Can't download apps from market
3. If an app is installed to external sd, it will install.
4. If anything is put on the phone (pictures, apps, music), it will be removed after the phone is restarted.
5. Capturing picture from camera, if the file put in internal memory, it can't be opened or sometimes error.
6. Receiving mp3 or mp4 file from bluetooth that put in internal memory, all files gonna error & can't be open.
7. can't root the phone because everything is WIPE while restarting the phone include the update.zip that placed in internal memory.
8. some old photos can't be delete from internal memory, once the phone is restart, those photos are appear again.
Attemps to fix include:
1.Formating internal and external sd
2.Wiping data in recovery
3.Flashing multiple roms in recovery
4.using odin with repartition checked
now i'm using JI6
anybody can help pleaseeee.
thank you
Wait, you used ODIN and the other account is still logged in? If that's the case then it doesn't sound like ODIN is working. ODIN if i'm not mistaken is basically re-writing everything from the ground up, bootloader, recovery, radio, kernel, rom. Can you give us a little more info such as what happens when you flash another rom, or after you use odin.
One other thing, you mentioned that you can't root the phone, yet you said that you have tried to install other roms. Are you sure you're doing everything properly? In ODIN does the console recognize your phone? Can you get into download mode?
Yeah, something in the OP is NOT correct.
OP, could you try the ALT METHOD in the NOOB GUIDE in my signature. It will take care of everything as I have used it many times as well as others. It will give you root, jk2 froyo and then you can flash on top of it.... no way in previous data should be stored.
Also, didnt see you listed a factoy reset which is in the settings options.
@Paging :
Of course Odin recognize my phone & I can get to download mode or recovery mode. I try using odin to flash the ROM to JI6. But everthing inside the internal memory is not wipe. Not much differences after flashing. But everytime I restart my phone, there is a pop-up message that said "sorry can't open maps....." or "sorry can't open amazone...." Those old photos that stored in internal memory is not wipe and the gmail account also not erased / remove.
As I said before, I don't know what should I do for rooting since the phone gonna wipe out all new file. When I put update.zip in the root, it's wipe when I restart my phone. So, how can I use this file in recovery mode ? When I choose "reinstall package"... it said :
E:can't open /sdcard/update.zip
(no such file or directory)
Installation aborted.
I tried using "one click root". It's useless either
What I've done so far is : I can flash the rom to JI6, JI2 and JK2 (all using Odin). Now I'm running in JI6. While flashing using odin, I don't tick the "re-partition" box. So far this this phone is working, but have much trouble as I mentioned above.
@s15274n :
in your noob guide, it said that :
I have already renamed the file update.zip so all that is required is moving this to your internal memory, NOT in a folder. You should use a file manager (or your PC) so that it appears like this:
sdcard/update.zip
1. Download the attached zip and rename to: update.zip
2. On your device, navigate to Settings > Applications > USB settings and select Mass storage
3. Plug your device into your computer, select mount USB from your device's pull-down window
4. Copy the update.zip to the INTERNAL SD memory (~14gb on this drive, not the one w/ Avatar if you've still got the 2gb SD card in)
5. Turn your phone off.
6. Hold down volume up and volume down while powering on the phone, this should get you to a recovery menu, you may have to try this a few times.
7. In Recovery menu select 'Reinstall Packages' (use vol_down then power to select)
when I connect the phone to PC, I can see the 13.6GB internal memory. I can see the folders : DCIM, data, amazonmp3, mobi_drm, slacker svox, Android and SD (external sd).
BUT I can't see sdcard/.
There is another SD folder which is hidden folder.
I already put update.zip file in the root directory, not inside of those folders. But it's wipe after the phone restart. So I try the frustating way, I copy update.zip file to root, and to all those folder include the hidden SD folder. It still not working. All those files wiped after my phone restart.
I haven't install any program / application inside my phone because it's gonna wipe after restart. I check my "sd card & phone storage", it said that
Phone storage:
Total space 13.18GB
Available space 13.15GB
Application Storage :
Available Space : 1.6GB
Is that normal ? Why the application storage is so small ?????
of couse I try the factory reset. I already unmount internal memory & format it.
But... those old photos & gmail account is still untouchable.
any idea how to fix this problem ?
How if I using "one click unroot" ? is it safe ?
please help me.
try doing a phone data reset
you will find that under settings > privacy > reset phone data
also, make sure you're micoSD is plugged in. 2 mintues ago i was having the same exact problems as you were having so i finally decided to give it a one last go before calling it a night. I plugged my microSD card in and re-attempted to root my phone and surprisingly that did the trick....it could be just a coincidence though
good luck!
Unfortunately the phone data reset did not solve the issue.
OK, after playing with the phone somemore, I found out that I can temporarily root my vibrant using the OCLF 2.3.0 - Z4Root app; I verified this by running the "su" command under terminal emulator. However once the phone is restarted, the su/root privilege is gone and I would have to install OCLF and run the Z4Root app again to gain root access. I don't think this is normal?
What's strange is that I can flash different ROMs using Odin without any issue, but I simply can't root the phone permanently. Does any one have any more idea I can try?

OP,
I would:
- remove external SD card
- desktop > menu > settings > SD and phone storage > format phone storage.
- ODIN back to original stock, JDF. follow the ODIN instruction [URL="http://forum.xda-developers.com/showthread.php?t=734475]here[/URL].
This should put your phone back to the original stock. There should be none of the old system data, kernel, root or anything. Your SD card should also be clear of all old data, which could be preventing permanent rooting. From this point you should be able to root, install cwr and flash roms at will.
I don't think there is a way for data to survive a JDF odin nor an SD card format.

i think THIS is a situation where you SHOULD check re-partition on ODIN. your doings omething wrong on ODIN.

same, but some people suggest against it, but this would be a situation where i wouldn't listen to them because you really do NEED to erase everything.

@jamir5:
so what did u use for your ROM ?
Now I'm back to JFD... everything is back like the factory reset, but those problems still remains. At least there are no pop-up error message anymore.
I don't know what should I do now ? even factory reset or repartition using odin still can't help us. hik...hikss.....
I'm start to thinking that it's a hardware problem.
same here flashed to stock rom force closures are gone bluetooth working again but still cant delete wipe or access the internal sd..tried every solution u could but no luck..

[Q] Phone storage read only

I noticed that under settings > SD card & storage that my Phone storage shows being read only.
I was wondering what may be causing this and if there is a fix for it, because several of my apps no longer work (BeyondPod being the main one I miss) because they need an SD card to work with.
I'm running the out of the box firmware, rooted using amon ra recovery.
I do have an exchange activesync account that requires encryption and pin, not sure if that could be causing any issues.
I did try to search the problem but couldn't find any relevant threads.
do you have SD encryption turned on in settings?
Is that the culprit?
Looks like I need to download that modified Mail.apk
After I re-locked my phone to apply the last GB OTA with new radios, I noticed that when I booted my phone the entire /data partition was in read-only mode somehow and it was causing all sorts of weird problems as you could imagine. Simply rebooting to bootloader and hitting "factory reset" option on the bootloader menu fixed the problem. I was then able to write to /data again and everything was fine. Obviously this will clear it everything. I was then able to apply my nandroid backup though and restore my system to how it was before the OTA.

thats just my guess... turn it off and see if it helps
Started getting weird read errors when trying to read/write to the card while it was mounted in the phone with the password for the encryption already put in.
I think the card was going bad, or just got all FUBAR'd during the encryption process.
Deleted exchange acct, removed SD card encryption, put in new SD card, re-added exchange acct/re-added encryption, everything works!

[Q] Phone wont boot and cant flash anything

Okay, this is quite a long story, so I apologise in advance.
I decided to update my Galaxy S2 today to a newer ROM (SuperNexus 2) with the latest version of Android. I was coming from a CM9 build. I went through the usual process of backing up data and performing a full NANDROID backup via CWM Recovery, booted the phone again and transferred the backups to my PC via USB. These files transferred fine.
I then downloaded the zip files for the new ROM and proceeded to copy them to the internal storage of my phone. The copy dialog in Windows said that it was "discovering items" and stayed like this until I turned off USB transfer mode on the phone and removed it (ie. the files failed to copy) This happened a number of times and I didn't get anywhere. I have plenty of space free on the SD card, but just to make sure I started the phone in CWM again and formatted the SD card, and since I was going to do it anyway, the data and cache partitions too. When I booted the phone again, the files still wouldn't copy. I managed to copy a text file to the phone which was about 32kb but anything larger just seemed to fail.
I then went back into CWM and decided to partition the SD card, as I thought that it may have been corrupted somehow and needed to rebuild the filesystem. This however, caused even more problems as trying to format the SD card (In CWM) now just reported "Error, can not mount E:/sdcard".
Feeling fairly frustrated, I decided to download the Stock ICS ROM for the Galaxy S2 and install it via Odin, thinking that the problem was probably with CWM. The install went fine, but upon reboot the phone just stayed on the boot animation, no matter how long I left it. To make sure the install went smoothly I decided to try and reinstall the Stock ROM via Odin again, but now Odin didnt seem to get past the "Initializing.." stage.
So all in all, I now have a phone which wont boot into Android, cant copy anything to internal storage, and Odin wont seem to connect to.
I am convinced this is a software issue and therefore fixable. But maybe the internal storage was not working correctly in the first place. I have installed many ROMs before and never had such issues.
Anyone know anything about this or how I could potentially fix it? Thanks so much in advance!

I9100?
Can get to DL mode?
Can get to recovery?
Get an older Odin version and flash siyah just to see if it can be flashed again.
If you can get to recovery, Nuke Script is the way to go.
It sounds to me that maybe your memory is corrupt...
Not just yet, smells like soft brick.

[Q] RemICS install in Galaxy i9000 halts

First off, I am no expert so please be gentle! I previously rooted my old Samsung Galaxy S i9000 and installed ICS, which went OK, but the phone became quite slow and unstable. I was advised to install RemICS and downloaded all the zip files from this forum, and put them on the external SD card. I followed the developer's instructions to the letter, as well as reading everything I could find on the subject. The reset and data wiping went fine, but the installation of the ROM didn't. It halted with an error message -`ROM incompatible, trying to use an invalid partition'. I repeat that this is supposed to be the specific ROM for the i9000. The phone now won't boot into recovery. It stops with an orange Android logo and the text `Powered by Mackay Kernel'. It won't boot into download mode either. The Mackay screen stays there however long I leave it. I really need help from the ROM developer but I can't post to that forum. How can I either boot into recovery or into download mode? Is this ROM reliable? What could I have done wrong?
More info:
Presumably everyone is on holiday! But just in case anyone is reading, there is further news. The reason I could not start recovery mode was that the button sequence was different from what I had been told. It now boots reliably into Mackay (which of course is TWRP). I have found that the phone is unable to mount the partitions DATA and SYSTEM - they seem to be corrupted. Hence it has not wiped DATA, although TWRP wrongly reports success. I have tried updating the partitions to ext3 or ext4 but this fails every time. I could format the thing from Windows but that will wipe everything including recovery of course. I need a tool to repair these partitions, but have not found anything so far. This may well have been the reason the phone was getting creaky in the first place.
I have copied a new ROM to the external SD card, using a card reader, and inserted this into the phone. Strangely the TWRP file manager reports that EXTERNAL SD is a sub-folder of SD CARD, and that is empty. The file manager does not show the real external SD card. But the real external SD shows up on the Windows USB connection. What is going on?
When I try to mount the partitions, DATA and SYSTEM can't be checked - the other partitions (Cache, sdcard, and emmc are all checked).

Well for the benefit of anyone else with the same problem, I have managed to re-flash the ROM back to stock. It just took 3 days of intensive web browsing until I understood how to do it, and found software that worked - a lot of stuff out there has errors.
To summarise, the problem was:
1. Data and System partitions became damaged, so phone became unstable.
2. Attempt to upgrade ROM failed because of damaged partitions.
3. Could not boot phone into recovery or download because button combination was different from what I was told.
The solution was:
4. Boot into download mode using correct button combination.
5. Re-flash back to stock ROM and re-partition using Odin.
Yes, someone did tell me that, and I would have done that straight away if I could have gotten into download mode. We live and learn
The solution was:
4. Boot into download mode using correct button combination.
5. Re-flash back to stock ROM and re-partition using Odin.

Upgraded CM and now cannot access encrypted internal SDCardo

Hi there,
First of all, I know that part of this mess was my fault. I had been using CM 10.1 on my Galaxy S2 for quite a while (since 2013, IIRC), but yesterday I decided to upgrade it to CM 12.1. The "CM Updater" app was not working so I decided to just download the .zip file, reboot into recovery mode and flash things from there. I managed to enter the recovery mode, but when I tried to flash the new CM I noticed I couldn't see the .zip file on my internal SDCard... Hmm, this was because my phone was encrypted (including my internal SDCard, of course). So I went back to my browser and did more research. I found a guy saying that, if your phone was encrypted, you could flash your device using the sideload mechanism *or* an external SDCard. Since I have an external SDCard, I chose this option.
Well, it doesn't much to figure out that things went bad. The main partition was overwritten during the installation and I've lost all encryption. However, that's not the worst part: I've also lost access to my internal SDCard! Now I cannot even make Android ask for its password. I really don't know what to do here. I've lost access to photos and videos from years ago. If I am correct, the upgrade process *did not* touch the internal SDCard at all; so my data is still there. Am I right? Do you guys think it's still possible to access it? I spent several hours trying to figure this out without success, so I decided to post my question here before I give up and reformat the internal SDCard.
Thank you in advance!
I am curious, how you manged to encrypt sdcard0 at all.
Never figured out how to do this on CM.
Nevertheless, I guess, Terminal/ADB might be the only option to decrypt and mount that partition. Unfortunately I don't know the commands on Android (on Linux it's cryptsetup).
