[Q] Downgrading 3.1 to 3.0.1

i wanted to know if i can downgrade from 3.1 stock to 3.0.1 using acer recovery tool. I want to downgrade because some of the apps that i would like to use keep force crashing on 3.1. i have tried reinstalling the apps and nothing works.

If you made a nandroid backup using clockworkmod (you should have), just do a full restore. ba-da-bing.
The acer recovery tool you mention is just for installing clockworkmod, it won't install a rom itself. clockwork mod does that.

i didn't create a backup so i guess i'm out of luck.

Maybe you are not... Dexter provided a stock rom on his first post here:
http://forum.xda-developers.com/showthread.php?t=1121790

Check this post. flashing those 4 files (don't forget itsmagic), will put you at version 1.104.02_GEN1_COM (U.S. Stock).
Skip flashing the recovery if you don't want to lose ClockworkMod.
http://forum.xda-developers.com/showpost.php?p=14967064&postcount=206
If you want a specific version, ask someone to uplaod a ClockworkMod backup of boot, system and flexrom and use ClockworkMod to restore it.

thanks euclid. I might try this later but i can't figure out itsmagic. I installed the clockworkmod recovery with acer recovery installer. Can i just boot into recovery after that and have itsmagic work?
edit: i got its magic running then did the steps in the post minus the recovery. when it was done the device rebooted and got stuck on the acer logo. after that i booted into clockwork and installed the 3.1 update.zip and now my tablet is working fine again.

From Official 2.3 to old MIUI?

Hello. I downgraded from MIUI to the 2.2.2 (dload folder on sd card method)
then i upgraded to official 2.3 using dload on sdcard method.
How to i revert this?
I have tried using the 2.2.2 dload method, then boot into pink screen to install newest recovery, the recovery works and i can restore my old MIUI, BUT it wont boot. just stuck on the new Huawei logo.
and yes i have tried let it boot right after the 2.2.2 dload method is complete but it then enters recovery and some error massaged are displayed, and it wont boot the rom, just recovery..
Any Suggestions?

Why did you upgrade back to 2.3 if you were planning to install .32 Miui? You have to have .32 ROM installed when you install Miui .32, .35 when you install .35 Miui. If I misunderstood and you have .32, try Fixing permissions in CWM.

Currently i have the Official 2.3 because i cant get any other rom to work..
But i want to get back MIUI, my question is How?
I upgraded because i wanted to try the Aurora 4.0 rom, but i gave up as i couldnt get root on the official 2.3 with superoneclick or any other app.
Thanks
btw. How does the U8800 work? I cant flash MIUI on top of the official 2.3 because of the kernel not compatible right?
and in pink screen, is the Boot.img the kernel? if so can i just replace that one with an older kernel and MIUI will work?

Go to settings/backup reset
There's an option install update from sdcard
That should do it

I see you're familiar with the "usual" way of downgrading...try doing it again, or a couple more times. When I upgraded to .35 to try Aurora ICS I had to flash the rom (ICS) like 3 times before it booted properly (was getting a bootloop before). Also if you don't apply the update (downgrade) more than once you can get a few "traces" of .35 system apps in your .32 rom (I downgraded applying the update only once and now have apps like 2.3.5's file manager, notes app, appinstaller, in my .32 rom.I didn't notice any problems apart from that though.). Hope it helps.

Hi there - I had similar troubles after I updated to stock 2.3.5 (latest edition) bootloader is now locked and previous exploits no good
Here is what I did:
Reflashed with 2.3.5 beta using vol+vol- I found it on XDA, can't remember where at the mo
then used superoneclick -worked fine
However my phone got stuck in boot loop after I tried to install CWM however I found that adb still worked and I used that to mount .cust_backup as rw and copied CWM recovery.img on there then took battery out and rebooted in to CWM and did factory reset and personally i installed aurora ICS 2.0 (2.02 gave me simcard issues) it all worked fine - took some fiddling for me but I hope this would make it easier for you

CWM 5.5.0.4 and 5.8.31

what is the difference between CWM 5.5.0.4 and 5.8.3.1. Why ROM manager installed CWM 5.8.3.1 in Galaxy Tab P7500 while taking backup, though CWM 5.5.04 was already installed using ODIN I.85. Is it necessary to re install CWM 5.5.0.4. If so, how to re install CWM 5.5.0.4. My galaxy TAB P7500 is running on stock ICS 4.04.

Only a few changes are made(you can't even say where)from 5.5.0.4 to 5.8.3.1...
The ROMmanager must make sure that the CWM on your device matches with the version of the APP,but upgrading does no harm i.e. it's no need to reinstall CWM...
Beware!don't go into CWM if you are on the stock ICS because it has the rolling screen issue,flash all you need with ROMmanager,don't install CWM touch when you are using stock ICS(it'll be a waste of time,mony,etc)
If you want to get out of CWM(5.5.0.4) after flashing but get confused with the rolling screen just do thisress vol down and then press the power button twice...the tab restarts with all the changes you've made...
And finally:feel free to ask questions,XDA in always here to help you!

I'm using CWM 5.5.0.4 here with stock ICS. No problems at all.
5.5.0.4 is the version recommended to prevent rolling recovery.

I also followed pershoot's advice in the 2.6.36.4 thread. I did get the rolling recovery even with 5.5.0.4.
I am on stock US ICS and odined the following:
(1) US ICS 4.0.4 BL variant
(2) Recommended recovery (CWM non touch 6.0.1.2)
Now I have no flicker in the recovery or the ROM like I had experienced in the past. However, I'm rather way of CWM 6.0.1.2 because I used the previous non-touch (6.0.1.1 I think) and wasn't able to restore a Nandroid...it just hung on me. Where did you get the 5.5.0.4 that worked with stock ICS ROM/BL Jack?

Hi dj.
Can't remember now where I got 5504, read so many guides.
I have it in my drop box.
I'll post the link for it shortly.

Really

You're welcome.
Good luck.

Thank you for your nice advice and assurance. Sir I have another question/doubt. Please clarify
I am having P7500 in India. I flashed Italian stock rom 4.04 using ODIN. Later rooted the Tab using CWM 5.5.4 method. subsequently I installed ROM Manager. I did back up. It appears that CWM version was changed by ROM manager. Now I want to flash Indian stock rom 4.04 recently released and also rooting. Please suggest a mode.

Download the stock IN firmware from Sammobile and flash in Odin with PDA with your tablet in download mode. You will lose everything on your internal storage so if you want to keep your backups make sure to move them off the tablet before you flash.
You'll find lots of guides in the Q&A and Dev sections that will provide root methods for your 4.0.4 stock firmware. Or, you can skip all of this and just flash a rooted ICS ROM with a full wipe to save yourself the steps. It's really up to you.

Thank you Sir for your valuable advice.
Please clarify, If I flash INU stock ROM 4.04 on ITLY stock ROM 4.04, using ODIN, will it wipe out applications data also?
Earlier When I flashed ITLY stock ROM 4.04 on my original stock ROM 3.2 INU on my galaxy tab p7500 using ODIN, it did not wipe out any data from internal storage and all the applications were automatically installed after reboot..

It may, it may not...it depends on whether or not you boot up after the flash without issues. If you get stuck on the Samsung logo or a boot loop, you will need to boot into stock Android recovery and do a factory reset, that would format your /data partition and result in loss of apps etc.
That Thanks button works well if I have helped you makes me look like less of a noob! Good luck to you

I recommend doing a full wipe with CWM recovery before flashing with ODIN. Doing that avoids having to do a full wipe with Stock recovery which wipes the internal. Wiping before flash should avoids formatted internal. Would others confirm, this is what I have noticed on my tab.

Try installing CWM recovery. Either 1.7.2 or 1.7.3. Then do your wipes and formats.

[Q] Can't access CWM - Can't boot

Hey guys,
I am really going crazy with my A500 and I really need help!
I tried to Update my Taboonay to the newest Flexreaper Edition. In the desciption it said that I need to have one of that custom recoverys to use Aroma installer. Because I had CWM with Thor 1.3.4 and 1.7.3 is neccessary I wanted to Update CWM via installing the zip from SD Card. Before installing the zip I accedientially deleted the update.zip from the SD Card. Tried to restart CWM than but it didn't work out and I could not enter CWM. I was stuck on booting recovery kernel image, waited about a minute and than the screen turned dark. Since that point the tablet doesn't start anymore and the tablet does not enter CWM.. What can I do to fix it?
I summarize:
- can't enter CWM
- cant boot the ROM
- deleted update.zip
Thank you in advance

I would guess, you are still running an HC bootloader? You must update your tab to the V8 unlocked bootloader from Skrilax_cz.
