TWRP 2.5.0.0 for Onda V972 Android 4.2.2

Hi, Everybody!

I still don't understand how Onda mount internal sdcard in recovery. When you mount data partition, you can find sdcard in /data/media/0, but I can't use it, because it's not block device.

Anyway I build TWRP 2.5.0.0 for Android 4.2.2 with only External microSD support.

Installation

Recovery partition in 4.2.2 now is nandd, so you can install recovery with command

su
cat /sdcard/recovery.img > /dev/block/nandd

be sure to have recovery.img in /sdcard root

you always can boot into recovery with command

/system/bin/reboot recovery

PS

If somebody can help with sdcard in 4.2.2 I always ready to cooperate!

Hi, Ankar.

After install the new TWRP my Onda is in bootloop, and it´s imposible shut down. If hold power button, he´s reset, not shut down.

Any idea for it?

This is the first time that I bricked off a Allwinner :confused:
[Miscellaneous Android Development] ankar84:
No, you didn't bricked your Onda! Yesturday I had the same problem. You need to push power button till tablet shuts down. And then very quick push home button. On your computer you need to do usual Phoenix Suite stuff. And now, when you hold home button you plug usb cable and do a short presses to power button till Phoenix Suite start to flash it. Don't worry! I will help you anyway...

The main quistion is how you get bootloop.. I think you copied recovery.img not in nandd...
[Miscellaneous Android Development] enr88:
Mine working fine, but i've a bootloop with the twrp beta1..but now with this new version all is ok.

For resolve the bootloop you should flash with phoenixsuit;)

[Miscellaneous Android Development] STEVE_MARS:
Thanks a lot!

jejeje, I need three hands, one for each button and for USB wire :silly:

I think that the cause had been because I copy with root explorer recovery´s files, my computer not recognized Onda internal SD.

I´ll check it again, after that my history second chapter, jeje.

Thanks again :good:
[Miscellaneous Android Development] Strypes84:
Thanks for this, so far looks good on the A31 Onda V972 v2 that I have, only problem I see is that I can't seem to mount the Internal SD card via USB. The menu comes up, and the selection of the card comes up, but either I'm blind or there is no button to actually start the mount. Any help would be great! Thanks in advance.
[Miscellaneous Android Development] STEVE_MARS:
Fabulous, ankar84 !!!!!!!

It´s working, and after modifiy nand in updater.script, my new ROM 4.2 based work successfully !!!!

Tomorrow make changes to better perfomance, and upload to my blog.

[Miscellaneous Android Development] tcampomanes:
Should we change the script?

thanks
[Miscellaneous Android Development] ankar84:
All instructions in that post.

So, if you want to install TWRP with script, yes, just change partition for recovery to nandd
[Miscellaneous Android Development] tcampomanes:
Thanks ankar84 , work fine in onda v972 with firm 4.2.2 beta.
[Miscellaneous Android Development] zcink:
Okay, I just got my Onda V972 32gb tablet today.

Rooted went fine.

Then installed the TWRP recovery in post #1.

Installed fine.

Booted into recovery and tried to do a backup of stock rom to internal SD.

Failed.

Then when I tried to reboot it says no operating system.

Stuck on 4 core boot screen. Held power button till it turned off.

Now the tablet will not boot. Nothing. Dead. Bricked?

No power will not turn on.

What do I do now?

Please Advise.

Thanks!

Update: After doing extensive research I used PhoenixSuit and flashed the latest V972Cor4-V2_v2.3 .img file and it worked. Its in Chinese but I do have a bootable rom now.

EDIT:

I found no easy solution, so I made some modifications and compiled TWRP 2.5 from source against the latest Onda Kernel (SDK 3.2)

ATTENTION: Only tested with the 3.2 Firmware!

Does not work with 2.0 ROM's and below. Definetely! :cool:

It might work with 3.0...BUT AGAIN: NOT tested and it might brick your device!

Download

******************************************************************************************************************************************************************

Worked like a charm up to SDK 3.0.

Now tested with the new SDK 3.2 and just booting into TWRP, than rebooting into System, is corrupting the ROM.

Does TWRP writes something to the device's file-system, even when it's just starting?

Device Onda V972.

My steps:

installed TWRP 2.5.0 on my device

than reboot in to recovery. Went well, but TWRP needed a long time to start and after starting, the Touchscreen didn't work.

turned the tablet off and than on again, device is booting, but stucks at the boot-logo.

no chance, to get it back to life.

Had to flash stock recovery via ADB.

Than booting into stock-recovery, factory reset and everything was ok.

Tablet was booting fine.

It seems that there is some incompatibility with the new SDK 3.2 + TWRP

But partition table is the same:

cat /proc/partitions
major minor #blocks name

93 0 20480 nanda
93 8 16384 nandb
93 16 16384 nandc
93 24 786432 nandd
93 32 2097152 nande
93 40 16384 nandf

93 56 524288 nandh
93 64 131072 nandi
93 72 11022336 nandj

"nanda" seems to be larger than before?

Does youre new compile works at your Onda V972 with firmware 3.2?

I have the same situation:

I own a Onda V973 V1 and up to Firmware 3.0 I am able to use the TWRP 2.5.0.0 from the V972 without any issues (backup and restore of course).

After I flashed firmware 3.2 I flashed TWRP 2.5.0.0.

I rebooted into recovery (works without problems) and made a backup (works without problems too).

After I rebooted to normal mode I see that a lot settings are deleted (e.g. wifi is not working anymore, keyboard settings are lost, my launcher does not run anymore and so one).

I will reset the V973 and try your compile as soon as possible. :good:
[Miscellaneous Android Development] hurray:
Hi vel! :)

Your version works pretty well, thank you very much! :highfive:

I am able to backup and restore my V973 V1 under the firmware 3.2 with your modified TWRP 2.5.0.0.

The only thing I have seen was a really long foldername under /mnt/sdcard/TWRP/BACKUPS/<extreme long number>/<date of backup>. Is this for a reason?

Cheers,

hurray
[Miscellaneous Android Development] hurray:
Hi vel!

New informations:

Backup to internal sd-card works but I can not choose the external sd-card as target for the backup anymore, only the internal sd is choosable.

Under "Mounts" I can mount the external sd and I can access it via the file manager of TWRP.

I have enough space free on the external sd and its formated with FAT32.

Do you have any ideas?

It is all what you expect from a cheap tablet as this.

I realy like it for what I am using it for.

It helps me to do my work, I use Tethering on my phone to make conection to the Internet.

It is realy fast and the graphics are great.

The only thing I dont like is the battery drain.

And I found many of them, but the problem is I want to back up my original (Stock) ROM, in-case if anything goes wrong or some defect in the cell.

So these are my questions:

1. How to make a backup of my phone's full Stock ROM, Might need if something goes wrong with the device

2. And How to Restore back to the Stock ROM that I created.

I will be really glad if someone help me pls.
[Android Q&A, Help & Troubleshooting] amith007:
Install the Clockworkmod (CWM) recovery in you phone.. then you have the option to take the backup from there.. So if anything goes wrong, you can boot into CWM and install your backup..
[Android Q&A, Help & Troubleshooting] BleedingIris:
1&2. You can't.

Unless you can download a compatible software (your original stock Rom ) leaked by your company (symphony )

After rooting(if you succeed )you may full backup of your rooted Rom with cwm recovery.

I wanted to install one of the ROMs from www.yorch.net. But before doing so I have some questions:

1. If I choose to build ROM as an installer.exe, is installing it to my device as simple as running the .exe file? (of course with the device connected thru Activesync)

2. Is my present ROM (see specs below) supported?

3. If Murphy comes to visit and I screw up, will my phone be completely unusable or can I just reinstall old ROM, do hard reset and everything will be back to how it was?

My specs:

OS: Pocket PC ver 3.0.12039

ROM:3.20.06 ENG( 07/30/03) (O2 Asia I think since I bought it here in the Philippines)

Radio: 4.21.00.

Thanks
[MDA, XDA, 1010 Software Upgrading] Rudegar:
1 as far as i know yes havent don it to my own device yet though

2 a rom dont have to support a rom since it'll overwrite it

3 of cause merphy can also show his ugly face

but if all fails a sd flash reader writer can save many a tears

also if your phone is working ok then i would not mess with the

radio stack and beware because some roms include the radio stack

and if you try to update your radio stack to a US (900/1900) and you network is 900/1800 you could be in for a world of pain

ROM upgrade step by step

OK I'm really dying to give it a go but I'm just a overly cautious bloke. So I'm gonna outline what I interpreted (after reading lots of posts I think I'm getting it but not sure) to be the way do the upgrade. Please correct me if i'm wrong:

Equipment I have:

1. My notebook (Windows XP, Activesynch 3.7)

2. O2 XDAI

3. Cradle and USB connection.

Steps that I think I should take:

1. Place XDA on cradle and make sure it's connected with PC.

2. Backup?? (not so sure what to back up since contacts, calendar, notes are synched with outlook, docs are also synched, I have copies of cab and program files since I download them to PC before installing them to XDA.) If i'm missing something please slam a frying pan (this is a kitchen right?) on my head.

3. Go to www.yorch.net, check mark on all appropriate options, then (since I have to Unix box and dont know Unix at all) just go for the easy option of cooking the .exe install file.

4. Assuming, the .exe is downloaded to my PC. This time I just run it. I expect this to be just like installing PPC apps. If not, throw a tomato on my face :)

5. Assuming everything worked and Murphy's in the Arctic freezing his A**e off, then all I do now is hard reset.

6. I have a new ROM and I'm singing happy-happy-joy-joy.

To the wonderful people at xda-developers, am I in the right direction or am I as lost as Bill and Ted? If I'm lost, is there a step-by-step guide for non-unix programmers? (Sorry, there was a sticky but I thought it was for people with Unix boxes)

Once again, thanks for all your help and your patience.
[MDA, XDA, 1010 Software Upgrading] Rudegar:
well i can think of one thing to backup and thats your current rom

so if you dont like the new rom you are getting you have the option to go back

of cause if the rom you have now is downloadble from a place you know like your isp then maybe it dont matter
[MDA, XDA, 1010 Software Upgrading] gekkko:
Thanks for the reply. That's a good point. Question: When you back up old ROM, is it just the ROM that gets backed up or is it the whole content of the device, like how you do in PCs?

Also, since no one, besides you, has made any comments regarding the steps that I outlined, is it safe to say that they are the correct steps?

Thanks
[MDA, XDA, 1010 Software Upgrading] ebswift:
When you backup your ROM, no stuff that you customised will be in the backup - the backed up ROM will be the same as when you received it from your retail shop, or if you upgraded, it will be the upgraded ROM without any of your stuff. Do a backup and store it on your hard disk.

DON'T use the .exe cooked ROM, use a .nb1 or .nbf, and use XDA Tools from this site to do the upgrade. It's very easy that way, and less dangerous. Don't upgrade your radio stack unless you know exactly what you're doing, or your phone supplier has made an update available just for you.

If you use a T-Mobile ROM above version 4.00.05 it blocks the XDA-Tools from updating the ROM. At that point you need to use XDARIT (from this site) to low-level write the ROM image you have onto your SD card using an SD card reader which shows the card as another drive on your computer. Once you do that you need to boot into the boot-loader (press the reset button while holding the power button) and follow the prompts to restore from an SD card. If you're unlucky and are running bootloader 5.17 (or above I think) you need to write the bootloader diagnostics patch (wallaby patch from this site) onto your SD card first before doing the boot into the bootloader thing. You can then remove the SD card, write the O/S ROM onto it with XDRIT, and put it back into your phone while it's still sitting on in diagnostics mode. Then you can restore from the SD.

It sounds complicated, but it's easy, as long as you have an SD card reader, and as long as you don't mess with trying to update the bootloader or do an unknown radio update. There's lots of info in these forums if you get stuck.

I made a thread that summarised all the steps using the new tools and ROM's at this address : http://xda-developers.com/phpBB/viewtopic.php?t=3860. It's for Asian/European users, but if you are in the US the instructions are the same, except instead of using European 900/1800 radio you use 900/1900.
[MDA, XDA, 1010 Software Upgrading] gekkko:
Further questions on ROM update

Thanks. It's becoming clearer and clearer. Have more clarifying questions:

1. How do you know whether or not you're including the radio stack with the ROM upgrade at yorch.net. I did not see any options there.

2. At www. yorch.net, nothing happens when I press the "Build ROM Now" command button. Is the download supposed to happen in the background or is there something wrong with my PC or the site?

3. I dont think I'm using the T-mobile ROM but how do I know if I'm runing bootloader 5.17? Is bootloader 5.17 only for T-Mobile users or all?

Once again, thanks for the help and bearing with a newbie.
[MDA, XDA, 1010 Software Upgrading] Rudegar:

Thanks

PS. Tried to email using the email utility at the website but getting errors there as well.
[MDA, XDA, 1010 Software Upgrading] ebswift:
OK, firstly to answer your question about Yorch's site... well it worked for me in getting all the ROM's I wanted, then when I went back again the download didn't work. I guess it's just on and off, so unless Yorch finishes getting married or someone else makes another kitchen it's a matter of pot luck. You can get away without using the kitchen if you can find another download source for ROM's, whether it be FTP or whatever. Just remember if you get an exe you can usually pull it apart with winzip to get the .nb1 or .nbf out of it.

Now, for Q1 :

An operating system ROM is generally just under 32MB, but when zipped from Yorch it's usually about 14 or 15MB - the operating system ROM will NEVER be smaller than that. I'm not sure about the exact radio stack size but I know it's a lot less than that. Also, doing some homework about the operating system ROM helps. eg. reading about the 4.01.00 ROM tells you that it's not a radio stack upgrade, it's an operating system upgrade - and the filename and the size of the file you receive reflects that.

Q2:

answered above...

Q3:

I think the bootloader is just pot-luck depending on when you phone was released. To check your bootloader it will reset your device completely, but I read somewhere that if you turn the radio (phone) off it doesn't hard reset. If you're worried, do a full backup first. But basically when you're ready to look, reset your phone while holding the power button and it will tell you the bootloader version. Don't be too turned off by that, I have read that SD card readers can be picked up very cheap if you look around, and that's all you need to get you out of trouble regardless of the bootloader version.

There's no real risk (but I won't guarantee anything), just make sure your phone is fully charged before mucking about with SD upgrades. Also make sure the radio (phone) is switched off before upgrading... using the bootloader/sd card method you shouldn't need to be concerned. I'm not sure what effect having your phone on and receiving a call while using XDA-Tools can have, but someone did mention it somewhere.

I'm a newbie too, but there's really not much you need to know, just a few caveats.
[MDA, XDA, 1010 Software Upgrading] pdhenry:
Yorch's Kitchen has been working OK for me the last couple of days. It takes maybe about 5 mins to "cook" before telling me that the ROM is ready. The 4.00.05 ROM gave me a lot of ActiveSync problems, so I went to the 4.00.16 ROM tonight and it looks like it's behaving better.

My SD reader is a Microtech Zio. It appears as a disk drive in windows, but the newer XDArit can't initialize a connection to write to the SD card. I used the "dangerous" older version of XDArit instead (available on Yorch's site), and it's worked OK for me (so far?).

One thing I wish I had realized before I started playing - going into the bootloader will reset your phone most (some?) (all?) of the time.

While I was flashing the ROM tonight I could see the GSM light flashing - I had the same "hope no one calls" feeling tht others must have had. Note that this was while I was flashing from an SD card in the bootloader - so apparently the process doesn't deactivate the phone while it's ongoing.
