getting back to 3.1.....??????? jessica

I gave up looking. I dont know what happen because i rooted my tab and somehow i cant go back. I did factory reset but no luck. I just wanna go to back to 3.1 so i could update my gtab to 3.2. I know its here in this thread but i cant find it (i tried) . If you could just help me out so i could update to 3.2 that would be a help. THANKS SO MUCH!!!!
JESSICA

Hiya, I haven't done this, but will try to help anyway.
Can I ask first, why do you want to go back to the "factory" state? Do you need to return it?
Edit: coz just having root access does not stop you updating to 3.2...

factoy reseting your device will NOT WIPE SYSTEM and thats were superuser is. You need to Odin flash the firmware of you choiche. thats the best and easiest way, its done in 5 minutes. And i think its wise to not update while rooted as some have reported errors during update and some have not. good luck

Why not just flash Galaxy Task 10 Rom? It's 3.2 and much better than the stock 3.2. All you need is Clockwork Mod installed and you can do that with Odin.
I flashed it with Pershoots kernel and it runs VERY stable. You can also flash it with the stock kernel if you don't want overclocking, etc.

I bricked my galaxy tab. I want to go back to 3.1 so i could update it to 3.2. I dont know much aout hacking so I guess i messed up. Im trying to go back to 3.1 so i could update my tab to 3.2 then root it. However, i couldnt find any thread to fix.
thanks for your all reply. If I used 3.2 rom? will it stay 3.2 if I use other roms? thanks in advance
jessica

Well, a custom rom like Galaxy Task 10 is "3.2" and so yes, it will stay 3.2.
I'd recommend Task's rom, it's much better than the stock 3.2.
And no doubt he will update to Android 4 (IceCream Sandwich) so you'll be able to keep up to date.
Your comments about bricking your device are now confusing the situation.
Can you please write what steps you did (or thought you did), and what your device does or does not do right now?
Also, please be vey specific about what device you have, whether it is 3g+wifi or just wifi. Give us the model number from the box if you do not know.
We'll help, we just need details.
Cheers..

i have the 16gb wifi us version. I used odin and
everything went perfect but still cant update to 3.2 using kies. Kies say your tablet doesnt support firmware upgrade. What I did next is i tried to root my tablet
somehow it wont let me root and giving me this "your storage not prepared yet please use ui menu for format and reboot actions"
I downloaded termulator and root checker to see if im rooted however it says im not. So I cant download any roms or upgraded to rom 3.2.
Ive been searching online to how to fix it for almost 6 hours and cant find a solution. pls help!!! THANKS FOR YOUR HELP GUYS AND I REALLY APPRECIATED!

1. Used ODIN to do what? Put in a recovery image? or replace a whole ROM?
2. Is a firmware upgrade available? There isn't for mine, I'm also on a 16g wifi version but no 3.2 FW has been released for my specific model yet...
3. How? By flashing a zip in recovery? Can you post the link to the information you used to do this?
4. These may give false negatives. Check in your apps list to see if you have "SuperUser". If so, run it, it will show you apps that have tried to ask for root access. They may have been asking but you didn't receive the prompt, and have therefore been denied root access. If so, grant them root and try to run them again.
5. Just FYI, you don't need root access to download/install a ROM, you need a "recovery".
Honestly, I think the best thing for you to do (besides answer these questions ) is to download the ROM Galaxy Task 10, boot into recovery, and flash it. That is assuming you do have a recovery image in place, which depends on the answer to #1 above.

i tried everything. it wont let me root the device. Tab keep saying your storage not prepared yet please use ui menu for format and reboot actions. So i cant use any or replace rom. I upgraded my tab to 3.2 before but kies keep saying its not upgradeable. Any suggestions? thanks!
jessica

Sorry, I need specific information to those questions from my previous post. As stated, replacing a rom doesn't need root, it needs a recovery image.
Maybe some screenshots of your tab and/or computer would help? Or photos, if you can't take screenshots?
Sorry, if you won't answer my questions I'm not going to be able to help.

ill try to post some pics. sorry!

Back to Stock,
Here's what I did to get back to stock.
You must choose the files under the GTAB GT7510 /retail/google edition
First you have to install Clock Work Recovery using this link:
http://forum.xda-developers.com/showthread.php?t=1171089
Download the files under FilesForDummies 2 mirrors are listed. These files will help you flash Clockworkrecovery and also the retail recovery is included.
This step needs to be flashed through Odin. You also need to root your device after the flash if your not already rooted. You need the Clock Work Recovery to enter recovery mode so you can flash the Stock Files that I'll point you later.
Once you've flashed the Clockwork recovery you should reboot normally. At this point try to root your device if its not already rooted. Look for OneClickRoot I'll point to that later if you don't already have it.
Not too sure if you need to be rooted as I've always rooted my device before installing roms anyways, but you can try the next steps if your not rooted. If the next steps don't work then reboot and root the device.
Start with your tablet off.
1. Push Powerbutton as soon as you see it startup put your finger on the volume down button and press until you see the android. One side is a box saying recovery the other download. Choose download mode by pushing volume down to choose and up to enter you will be prompted at this time just take if from there. Make sure Odin is up and running, choose the PDA file as Clockwork cm4.04 its that file in the zip you just downloaded and extracted.
2. Flash Clockwork file Clockwork CM4.04 etc... using ODIN should be included in the zipped file you've downloaded. Make sure these files are unzipped in the same folder. Now after flashing the tablet should reboot and it would look normally like it did before except you have clockworkrecovery instead of the stock one.
3. Go back to the link I sent you above and scrool down until you see flashing roms and kernals heading. Click on Stock US Retail Rom, this will download the Stock US Retail 3.1 file for Clockwork. choose : hc-3.1_ota-full_sam file, and then also click on the recovery hc3.1 file.
Put these files in the same folder or somewhere where you can find them. Not sure if these are already in the file you downloaded above, if they are then don't have to download these.
4. Unzip the files and make sure you remember where they are.
5. With your tablet on and plug into your usb port transfer the hc-3.1 ota file you've just downloaded and put it into the root directory of your tablet. It should not be in any folders just in the /SD folder.
5. Now turn off the tablet, once off push power button again and enter recovery this time choosing the left android with the box. Push left button to choose and right volume button to enter. Now you should be in clockwork recover orange writing. Now look for update from Sd card, use volume button left to choose and right to enter. Click then you should see the file you've copied on your sd card of your tablet. Click down and then use left volume button to choose.
6. Once there it should start flashing the Stock Rom, once done it will return you to where you started, at this point you can choose to wipe data/ cache etc. You can do that to make sure you've clear everything in your tablet before you actually reboot. Once done choose reboot and your tablet should be back to stock but not just yet.
7. You could leave Clockwork on there or you can go directly back to stock by doing the same steps from 1 and 2 and flash the STock Recovery instead. This will bring the tablet right back to HC3.1 and Retail Stock. From this point on you can flash up to 3.2 etc.
Hope this helps but I can't go into it in any length as I'm hoping you know most of the terminolgy.
There is also videos on this link to help you.

nice
I suspect that if we see screenshots, that the wrong recovery has been flashed right from the start.

Recovery / Bootloader

Ok, i realize i have a different phone from this thread but it is close and my problems closely reflect the issues ive seen with the Galaxy S.
A little background. Im no perfect i know what im doing when it comes to rooting. I have an HTC Tbolt and rooted many of those, an older touch pro 2, and this is first time doing a samsung. I am getting the hang of ODIN (i wish everyone would just use this program instead of bouncing back and forth between heimdall and ODIn but whatever) Im liking ODIN cause it works well. I was successful at flashing a new rom into this Samsung phone. 95% of it worked, wifi i think didnt but everything else worked. While trying to fix the phones wifi somehow i have stopped the phone from booting into CMW recovery unless forced or booting into a rom. I can get into CMW but i must hold down the Vol Down button to get there, otherwise a clean basic boot takes me to the stock android system recovery screen and will not boot a rom.
I have something backwards or out of order. I am just trying to get the rom to identify the installed CMW and the installed ROM through CMW but it wont do it.
Any help would be appreciated, i dont want my GF to find out i jacked her phone lol

Which phone do you have? SGS? I can just talk about SGS+ but I guess its similiar.
Try to install CWM with Odin, normally it should replace the stock recovery (haven't heard of both running at once).
Once you have installed CWM you can install your custom ROM with CWM (look at the install instructions).
If you want to install stock ROM with Odin it will replace your CWM with stock Recovery.
Post the link of the thread/recovery you want to flash.

Its a stratosphere. Im using the root and / or stock files in the root method. I use ODIN to flash the StratCWMRecovery.tar.md5 and if i tick "reboot" then it reboots into CWM i install a rom or stock rom and it finishes. I reboot the phone and it instantly goes back to android system recovery. If you like ill make a short video to give you an idea of whats going on.
I will note that im close to making a jig but its not 100% bricked obviously. 3 button method still works (and unecessary at this point since all the phone does is go straight into the stock bootloader) and then after i install CWM i can force it in to CWM but it wont actualy boot into it.
From a programing standpoint i feel the pointers or partitions are incorrect. Its like booting a computer that has a hard drive with windows installed however getting the bios to tell it to boot from the hard drive isnt working. THats the easiest way to explain this.
One thing i want to note is the only errors i am getting are when i try to partition the SD card from CWM. I get an error saying sdparted is not found.
I am not getting a full understanding of how the root system works on this phone.
Again any help is appreciated.
Made a short video. Its uploading now. http://www.youtube.com/watch?v=tFZ5Adm5AdQ

So whatever i did i was able to fix. I think me being a very visual person and normally having access to all files i need or could use in a situation is always nice. Here, i didnt but i found them. Here's the link. Its obviously for stratosphere but i took about 10 minutes and let ODIN install all these files and it worked.
original posting but the link doesnt work for download

where i downloaded it
http://www.fileswap.com/dl/t4D235pUTO/SCH-I405.EH2_rel.md5.html
Again this is for stratosphere. Since it really helped me return to stock and allow me to re root in about 15 minutes this thread should be moved but there is no stratosphere area

Chinese Atrix - Questions about FW, Bootloader, Root

Hi Guys!
I know, some people will hate me now because I opened a thread for that.
But the search did not help for chinese FW, so I wanna give it a try here!
I just got a chinese Atrix with the following information in settings:
System Version:45.2.14.ME860.ChinaRetail.en.CN
Android: 2.3.5
Baseband: BP_N_01.41.00R
Webtop: Unavailable
Kernel:2.6.32.9-00007-g9570040 [email protected]#2
Build number: 4.5.3-118_OLY-14
Superuser is already instaled and when i bootup the phone, "Unlocked" is shown in the upper left corner!
What I wanna know:
Is it rooted (yes of course, I think!)
Is the bootloader unlocked (never had a phone that says "unlocked" when booting up with an unlocked BL...)
Can I just flash CM9 for example or is there anything I should be aware of?
Sorry for beeing an Atrix n00b =)
And thanks for all suggestions!

The Unlocked text on the Motorola screen is an indicator that your device's boot loader is unlocked. I would recommend referencing the NOOB threads covering rooting and flashing ROMs for the rest.

Thanks for that!
But it's already rooted (super user is installed and I tried apps that need root).
What I wanted to know is, if I can just flash new roms or do I have to be cautioness, like many threads say: Don't flash back if u use build nr. xyz...

Check if you have cwm recovery installed. If not install the latest and flash the latest version of cm9 through cwm

Atrix 4g from Taobao 19 Apr.
Hi muhski,
I am in the same situation.
I just buy Atrix 4g from Taobao and receive it on 18 Apr.
When Gapps is not installed, I was very disappointed and call them to complain.
They ask me to send it back but I tried to get to know the phone more.
System Version:45.2.14.ME860.ChinaRetail.en.CN
Android: 2.3.5
Baseband: BP_N_01.37.00R (Yours is BP_N_01.41.00R)
Webtop: WT-1.2.0-163_11 (Yours is Unavailable)
Kernel:2.6.32.9-00007-g9570040 [email protected]#2
Build number: 4.5.3-118_OLY-14
Superuser is already installed and rooted.
Booting up the phone, "Unlocked" is shown in the upper left corner!
If you do a thorough search, you will know that to start to flash cm9, you need:
1. bootloader unlocked, machine rooted
2. clockworkMod (cwm) flashed
3. then flashing CM will be easy. Just put some zip files in root of sd card and then run ClockworkMod.
See but dun follow the cwm installation:
wiki点cyanogenmod点com/wiki/Motorola_Atrix_4G:_Full_Update_Guide
Your Atrix and mine are probably in stage 1.
Last night I tried to follow the old instruction in the link above to flash cwm.
But the fastest manner to run cwm is by installing Rom Manager instead.
Rom manager is super easy to use and I manage to get it to flash cwm in my Atrix. With cwm running, I boot from it and get cwm to flash Gapps in my Atrix.
Now I got cwm & gapps both running very well.
All my gmail, gPlay, gCalendar, gMap..... running quite well.
The next step I can make is to save cm9 zip files in the root of sd card and run cwm to flash it.
I am currently stuck like you. I wan to flash ics thru cm9 but worrying bricking Atrix. Moto may come up with ics for atrix real soon so I dun know if I want to wait.
Good luck

Sounds like you are on the right track. Once you have cwm flashed you can reboot, hold the volume down rocker as the phone reboots. Once you see another option under the "unlocked" text you can then tap the volume down rocker until you get to the recovery option, then tap the volume up rocker. This will bring up a whole new menu that you can use to clear cache, Dalvik cache and factory wipe.
When I flashed my first ROM I was very nervous that I was going to ruin my phone, but I have flash many ROMs since then some with gapps included and some that require you to flash gapps seperate. I have enjoyed many ROMs and have not run into any problems I couldn't fix by rebooting into recovery.
Good luck and enjoy the ROMs of your choice!

Hey guys!
Thanks for all your help!
First, I forgot to say, it's not the first time doing this stuff xD
It's my third android phone, so all is very similar to the Defy, but still I like to ask one time too often instead of crying about a bricked phone =)
What I have done now: Because bootloader was already open and cwm was already insalled, I could skip the hardest part and jumped right into flashing.
Ok, not really, because I updated cwm to romracers version (not really necessary, but everyone suggested it...)
Right now I'm running Neutrinos CM7 mod because other mods gave me randome reboots
First problem was: My Radio version does not work with this rom! "About phone" says "Baseband unknown".
I went crazy bcs I thought I got a broken phone from taobao, but smart as I am (hrhr) I made a nandroid backup before, flashed it back, and tadaa, with the old backup I had network connection....
So I googled a little more and found out about the Radio-Thread here.
Now I'm testing all the radios to ind the best one...
Good thing is, network connection is working now, bad thing is, it sucks my battery dry like a h**ker that gets too much money
@qqqqaa: does your radio version work with CM9?
Maybe I should try yours...

Can any of you with the Chinese ROM confirm that call recording works on your phone and if possible, do share a dump of your ROM.

Cannot root U8800Pro. SuperOneClick hangs at step #7

Hello,
I have a problem when trying to root my wifes U8800Pro. The SuperOneClick gets always stuck at step #7. I have done everything as instucted (enabled logging and usb debug, disabled fast boot, etc).
Before you say that I should search, this has been discussed before. Yes I know, I have searched and found couple threads, but they didn't help.
I'm guessing that the problem is that I have too new stock firmware? I had this in the phone originally:
u8800pv100r001c00b535
custnorc306d002
But now I downgraded (?) or upgraded to:
U8800Pro V100R001C00B512G001
And the SuperOneClick still isn't working. I don't know what to do. I can't find any older stock 2.3.5 firmwares and don't know if it would even help me if I could downgrade to some older version.
Could someone please help me how to root this phone. I have done Galaxy S before, but it wasn't this complex
BTW, the SD card stopped mounting when I flashed V100R001C00B512G001. I have to take it out and re-insert it to make it work every time.

I'll answer to my self. I don't know if all this is correct, but anyone can correct me if they want.
The stock roms can be rooted in various different ways. Most used options might be SuperOneClick and "pink screen" boot.img change.
SuperOneClick doesn't seem to work with at least newer versions of 2.3.5 at all. It's only usable in older stock roms.
Another option is using the "pink screen" method, with boot.img and it goes like this:
1. Power off, and then Power on with Vol + & - pressed to get to the Pink Screen.
2. Connect the phone to your computer with USB cable.
3. Browse the phone contents with your computer. You should only see one folder called "image". Go inside the folder.
4. Backup the boot.img file to your computer. You will deed it if you want to unroot / return to stock later.
5. Replace the boot.img with a rooted one. You have to find a boot.img specific to your firmware version. I haven't found one for 2.3.5. I'm not sure if they are different between U8800 and U8800Pro, but I guess they are.
6. Once done, detach the usb cable from the phone and restart it by taking the battery out and reinserting it.
You should have now rooted your stock firmware phone and you should see a Super User app in your app drawer.
But if you are going to load a custom firmware to your phone, there is no need to root the stock firmware. In this case you should use Clockwork Mod Recovery to load the custom firmware into your phone, because custom firmwares are already rooted.
It goes like this:
1. Power off, and then Power on with Vol + & - pressed to get to the Pink Screen.
2. Connect the phone to your computer with USB cable.
3. Browse the phone contents with your computer. You should only see one folder called "image". Go inside the folder.
4. Backup the recovery.img file to your computer. You will deed it if you want to return to stock later.
5. Replace the recovery.img with the CWM Recovery file. You need to make sure that you have the correct version for the rom that you are going to load. The needed version is usually mentioned in the rom description. I think the latest one is this: [Recovery] Unofficial CWM Recovery 5.0.2.7[u8800pro&u8800] (?)
6. Once done, detach the usb cable from the phone and restart it by taking the battery out and reinserting it.
7. You can now install custom roms with CWM Recovery by holding volume + and power to boot up your phone. Look at the install instructions of the rom you are going to install.
Be sure to backup your phone with CWM Recovery as soon as you have installed it in case anything goes wrong.
See how to create nandroid backups with CWM Recovery here.

I'm going to reply to this thread as this is kind of on topic... could someone more experienced answer at least some of the questions below, thanks.
Does anyone know where I could find stock firmwares for U8800Pro? I'm having hard time to find any even from Huawei's site. I only found this there and that says it's only usable in Russia.
I had this in the phone originally when I purchased it:
u8800pv100r001c00b535
custnorc306d002
Was that the newest stock firmware? Where can I find the newest one?
Is there a "rooted" boot.img for the latest stock firmware? Is the boot.img different for every firmware version? Is it different between U8800 and U8800Pro?
Is this the latest CWM Recovery and should I use that? I'm going to put some ICS rom in to the phone after I've tested the official demo version which is coming "soon" I hear.

I'll answer to my self once again..
Here's some stock firmwares for U8800Pro:
http://madmodder.co.uk/huawei/u8800-pro/huawei-u8800pro-firmware-list.htm
I guess the newest stock version is V100R001C00B572G001.
For the "rooted" boot.img I have no clue where to find one, or are they firmware specific or different between U8800 and U8800Pro.
As to the CWM, here's the official releases. There's no releases for U8800Pro, I don't know if it has different recovery.img as the U8800 has. I guess the one which I linked to is the latest "unofficial" version. Reading the comments seems to point that it works for some and some have problems. I guess that should be used still if you want to go for ICS rom.
Anyone care to comment on any of this?

I have the same problem i did every thing perfectly and i couldn't get to root my u8800 pro ... i tried super one click, z4root , easy root, unlock root , changing boot.img, ... i have my drivers installed correctly.. checked usb debugging.. disable fast boot....switched to logged on ( project menu ) and i still got stuck on step 7 on super one click.. another program mentioned.. ( adb server out of date.. ) and ( failed to copy superuser.apk due to system read only..) ... so I'm stuck now for 2 month..can any one help ???

Have you tried to restore HC boot loader on an ICS rom. Don't worry just download one of the update package from the following link. As you mentioned you were on ICS rom then try ICS update only as it will update boot loader back to ics. Decrypt the file using Acer decrypter on the same link. Place the update.zip on your externel SD and then boot in recovery. Let other recovery install the update file.

Only Acer logo
Hi all,
i have the problem that the A500 does nothing else but show the Acer logo.
The only thing i can do is use TWRP.
What did i try:
I tried flashing some roms using TWRP, also some older ones but no luck.
I tried using an empty SD-card and then start with Volume - and Power but no luck
What can i do...i am stuck...

Anyone? Still have a non-working Iconia 500...boohoo
Is it an option to flash it with Clockworkmod / CWM, reboot, flash it with an Acer ROM ?

Well, telling us you've "tried some other ROMs" and have had "no luck" is pretty much telling us nothing at all.
What ROMs -exactly-?
What -exactly- do you do in TWRP?
What version of TWRP?
-Exactly- what error messages do you get?
What bootloader do you have? Sounds to me like you might have the HC bootloader when trying to install a stock ICS ROM. This is not going to work, period.
If you want help, you've got to provide enough info to help you.

Hi FloatingFatMan,
thanx for your answer.
I tried TWRP v2.1.0 with following roms:
Acer_A500_4.010.42_7.006.01_COM_GEN1
Acer_A500_7.014.14_041.203.01_COM_GEN1
cm-9-20120708-UNOFFICIAL-a500
recovery-ra-iconia-3.17-
gnm
Today i updated TWRP to v2.2.0 using openrecovery-twrp-2.2.0-picasso-signed and tried the cm-10-20120730-UNOFFICIAL-a500.zip rom. Same problem, after system reboot i only see the acer icon (permanent).
Also tried cm-9-20120708-UNOFFICIAL-a500.zip but same problem.
What can i do?

There are three main ingredients when customizing a device:
1) BOOTLOADER
2) RECOVERY
3) ROM/KERNEL
You provided answers to #2 and #3....what about #1??? What BOOTLOADER are you on?

Thanks for your reply.
I never changed my bootloader so that will be stock i think.
Finally i managed to get it going again. The trikck was to use a 3.0 stock rom. That worked.
From there i now use ICS (stock) which is fine at first. I had not seen anything but the Acer logo the past 2 weeks, so the Acer ICS will do perfectly now.
But for later on: can i use CM9 or CM10 with default bootloader + TWRP 2.2.0?

There are three main ingredients when customizing a device:
1) BOOTLOADER
2) RECOVERY
3) ROM/KERNEL
You provided answers to #2 and #3....what about #1??? What BOOTLOADER are you on?

You'll need the unlocked ICS bootloader. Civato made a great guide over in the DEV section.

I never changed my bootloader so that will be stock i think.

OK to explain for you.
ICS and JB require the ICS bootloader to run. They will not run on the HC bootloader unless specifically modified to do so. Also, no HC ROM will run on the ICS bootloader. This is why none of those ROMs were working for you.
Flashing stock ICS has updated your bootloader with the locked ICS one, so you probably won't be able to downgrade to any HC ROMs, or use any custom ROMs anymore. You can, however, use APX mode to install the unlocked ICS bootloader which will enable custom ROMs again.
I don't recommend trying to install ANY custom ROMs now until you'd flashed the unlocked bootloader. Instructions for this are in the Development section. Read VERY carefully before proceeding and if in doubt, don't proceed.

Hi FloatingFatMan,
thanks for the explanation.
I think i will stick to the stock rom at first. The APX way is not without risk...but maybe in the near future...

I am having the same "stuck on acer logo" issue. I am totally novice when talking about how to flash to ROM and stuff. Can you please direct to me a simple "dummy guide" on how to flash back to factory rom and fix my tablet. I tried the hard reset by holding down volume up and pwr button and on/off button, where i see the 'erasing..." but it still goes back to logo screen.
Please help me with my situation. Thanks in advance.

Have a look at this video
That is an example on how to do it.
