[Q] Revert OTA 3.2 back to 3.0.1 HELP - Acer Iconia A500

I want to downgrade my a500 back to 3.0.1
http://forum.xda-developers.com/showthread.php?t=1276227
and i want to using method 2 to do it, but i cannot download the package since "This service is temporarily not available from your service area."
Could anyone upload that for me to finish my downgrade T_T
please help~~~

Is it possible that your location (country) is blocking Megaupload? If so then you could try one of the free vpn services to make it appear that you're located elsewhere. I've never used one (don't need to) so someone else might have a suggestion as to which one works well.

[ROM] Rooted Stock HC3.2 for European A500 (Acer_A500_7.006.01_EMEA_CUS7)

(Edit 07.11.2011: I was able to extract and modify the ROM. Send me a PM after reading the thread if you want the download link.)
Hi everybody,
I am sorry to post this in the General section, but the forum would not let me post to the appropriate threads of the developer forums as apparently I am considered too noob. Anyway ...
I have an Iconia A500 on Acer_A500_4.017.07_EMEA_CUS7, rooted with IconiaRoot.
I am being offered the OTA update to Acer_A500_7.006.01_EMEA_CUS7, but do not want to install because I would loose root.
So I would like to download the ROM from the Acer website and modify it according to the procedure listed here: http://forum.xda-developers.com/showpost.php?p=18202192&postcount=19
I looked into this thread for the download link: http://forum.xda-developers.com/showpost.php?p=14501467&postcount=1
Unfortunately, the link I need is not listed there. Does anybody know the link? Can I somehow extract it myself (I have root access and my A500 offers to update)?
Thanks a lot for your help!
Cheers,
Tim
Is it possible to accept the download and then halt the process once the download is complete? And then to copy the rom to your pc to fiddle with?
Sent from my A500 using xda premium
Hi,
I suspect that the download link might be extractable from the LogCat once I accept the download. But I am not sure if I can cancel the update process completely once I have accepted. So I am hesitant to try.
Cheers,
Tim
I understand if you just want to do it yourself. However, if that isn't the case this rom is all ready to go. Stock with only superuser and busybox installed. I've been using it for a while and it is rock solid.
There is another one too. I didn't try it out but, from the feedback I read, it is also working great for most folks...
Hi, and sorry for replying so late (I was on travel),
thanks a lot for the links, JdgM3NT4L! It is not that I actually _want_ to modify the stock ROM myself, but I have a European version of the A500 (EMEA_CUS7) and am therefore hesitant to just install a ROM based on a US version of the A500. I am not sure if there are actually any significant differences, but do not want to risk it.
I think I found the information on how to extract the path of the update in one of the threads of the developer forum (sorry, I don't remember exactly wherefrom):
3. Start a system update on the A500, and let the download start.
4. Start the Terminal Emulator (vt100), and type su . Then cd to the /cache area.
locate the file name of whats being downloaded. In my case: Acer_A500_1.141.07_4.010.11_COM_GEN1_1311224632952 _461992b1
5. Then on the PC create a full http path and do a download of the URL contructed
using the file name in your cache directory. Example:
http://cdn.acer.futuredial.com/Acer_...2_461992b1.zip

Click to collapse
I think I will try that. If it works I will report the download link here.
Cheers,

Hi again,
it worked like a charm. Here is the link:

The MD5 is: B80BB5A64BD694F1D615D4D3DD60C19A
Next I will try to modify the ROM according to these instructions:

Glad you got it. Good luck.
Hi again,
ok, I modified the ROM according to kekinash's instructions. It turns out the update script in the EMEA_CUS7 ROM is _not_ identical to the one in the COM_GEN2 version!
In line 27 of the script there is a very long entry starting with "retouch_binaries(...)". A handful of the entries in this long line are different in the EMEA_CUS7 ROM. I therefore replaced the line in kekinash's script with the one from the EMEA_CUS7 ROM. Everything else was identical.
I installed the ROM on my A500 and so far everything seems to work fine. But I will have to test it further to make sure there are no hiccups.
I guess other european users might be interested in the ROM image, but I am not sure if I can upload it or infringe any copyrights by doing so.
Cheers,
Tim
Hi,
My english is not good, so I hope you will understand.. I would be very much interested in your modifyed rom. I read the thread about unpacking and modifying, but I dont understand how to do it, possibly because of my poor english. maybe you couldt upload only the modifyed file, which I should change.
thanks
Udo
Hi Udo,
I will send you a PM with a download link for the modified ROM image. If anybody else would like to have it, please just ask and I will send you the link.
I played around with the ROM for some time. Generally, everything seems to work just fine!
One problem I encountered, though, was that the android web browser crashed badly and I had to reboot the tablet to fix it. Since then it worked fine. Also, Google Maps gave me a strange behaviour at some point: It just exited repeatedly without any error message (no force close). I do not know if these issues are related to the modified ROM image or if their appearance was just a coincidence. If anybody tries the modified ROM, I would be happy about feedback!
Ok, and the following is obvious: I take no responsibility whatsoever for any problems you might encounter when flashing this ROM image. Also, please follow the instructions given in kekinash's thread: http://forum.xda-developers.com/showpost.php?p=18146210&postcount=1
Cheers,
Tim
Hi again,
I updated the thread title so that people looking for the ROM have a chance of finding it.
Here is some more information. The MD5 of the modified ROM image is: D423B84727BFD91429490D319F30998F
In the meantime, I have tested the A500 with this ROM much more. The browser has not exhibited any further problems.
Google Maps continued to act up (kept quitting without error message repeatedly). In the Market, it was listed under "Not Installed", and I had the options "Install" and "Deinstall updates". Both options did not do anything at all. So something was clearly wrong. I still cannot say if this was related to the modified ROM or some other problem. Anyway, here is how I fixed it:
Removed Google Maps with Titanium Backup. Reinstalled from the Market. Converted it to System App again with Titanium Backup. Everything works fine now.
Cheers,
Tim

please help install telstra

hi everyone, after reading through some of the post , i was confuse on which method to use, currenly i'm with Bell canada running 7.10.8107 , i read that telstra enable me to use wifi tether. here the step if i'm not mistaken
1. download latest LG C900K Firmwares
LG-C900kAT-00-V10d-TEL-AU-AUG-15-2011+0_DZ.zip
2. use nasirahmed method with correct DLL (LGC900KB_100927_MP.zip) to install
3. after use zune to update to latest firmware or download
WIFI Tethering Drivers - 1.0.5.10 (December 2011)
Code:
http://download.windowsupdate.com/msdownload/update/software/dflt/2011/12/437223_lg-c900k_telstra_australia_1.0.5.10.pks_1e2a877b551d2497396bf1d07bf19c833d78381a.cab
and use this method to update
http://forum.xda-developers.com/showthread.php?t=1306415
please confirm if this the right way to do, is there any risk involve in this, will this relock firmware
thanks
Steps are correct. You might find some hurdles hear and there but just be patient and read ALL instuctions.
I did it and it's working but I'm now in the process of reverting my phone back to C900B because I'm not able to unlock C900K. Also, Zune will not update to latest firmware so you will have to do that manually.
If you don't have full backup you will lose everything from your phone.
Good luck.

Here's hoping that LG Canada will recognize that it can be updated to have tethering at all. So far they've told me it's physically impossible. Twice. Even after I've tried to tell them that it works fine with the Telstra firmware.
Good luck with the switch over if you chose to go that route.

firmware problem

i have a galaxy s which i flashed to remove t-moble branding, now not sure why but i can't get wifi working so want to go back to stock firmware. the problem is which is the correct version for me.
my phone is galaxy s gt-i9000 and was originally locked to to t-mobile UK. i'm looking on the stock firmware and odin guide but i haven't got a clue which one is suitable. i've also got a message in kies saying that 'your device does not support software upgrading via kies'.
please can someone advise me how to get the phone working correctly again? don't care if i have to go back to t-mobile branding as look as it works with wifi.
Hi Rincal...
first question.. did you have your galaxys unlocked to make it sim free by a shop or market seller.. if you havent.. this will cause problems, so make sure you get that done.. its about £15.
2nd) The latest stock firmware is 2.3.6.. the xda team have Eu stock ROM threads.. look in "development", but if you cant find it.. use this:
http://forum.xda-developers.com/showthread.php?t=1431596 - although i think there will be a newer version out now.. in the PIT folder, use PIT-512.
Here is a full abc flash guide
http://forum.xda-developers.com/showthread.php?t=1139050
Follow it to the letter, this is how I learned.. even though Ive had no problems, you flash your sgs rom at your own risk.. make sure you read it through first before you flash anything and always backup your data 1st.
Please note: This is not my work.. please thank and respect the xda teams named in the threads.
If anyone reading this thread can give better guides or links, please point the way
Good luck

hi NightOrchid
i used a market app called galaxy s unlock to unlock it myself. it was working find after that, the problems started after rooting and flashing.
i'll try your suggestions and let you know the outcome. i've already tried flashing with a few firmwares but always have the wifi problems. should say that apart from wifi and kies the rest of the phone seems to work ok with other firmwares.

Flashing from Chinese to Hong Kong - Backup

Hi,
I am new to android - coming from many years on iPhones. (Jailbreaking)
I just got a 7.7 (From the Taobao Samsung shop here in China, they had a trail version program where 300 people can pay a deposit and then use the tablet for 30 days and return it)
I want to know if the Chinese version is also able to flash to the Hong Kong version as this Chinese version is really a mess - no android market, no google access and a lot of stock Chinese software. (and I think a few monitoring things a well???)
Anyway - I have read most of the post on the 7.7 and it seems that there are some people who have had a hard time flashing the Chinese version? (It also seems to me like they might just have run into some problems)
As far as I understand, coming from a jailbreaking and server admin background, this should be really basic and should be easy to do?? One should be able to flash any countries firmware onto any 7.7 tablet?
I would also like to know if there are any programs one could use to backup your ROM and PIT and what ever is needed to be able to restore back easily if something should go wrong.
So I have read about Titanium Backup - would this work and where can I find a good guide?
Please let me know and I appreciate the help!
PS...I have the 16GB 3G version
I would be very careful about using a device made for the Chinese market. You might want to use your device for 30 days, then if you like it get a Hong Kong version. At least then you will know your device can be safely modified, and not subject to the same communication controls.
Need help, PM me. No worry. Get TITANIUM BACKUP. ROOT IT. FLASH CWM. BACKUP....and READ the forums:
http://forum.xda-developers.com/showthread.php?p=22775462#post22775462
Here's stock ROM in case you F%ck up -- you will, save the tears, get the file NOW and learn how to use ODIN!
http://115.com/file/an40wd58#P6800ZCKL4.exe
(ps. check this is right ROM, should be, 'about' in settings...)
@rmm200
This is what I have been planning and I think I will stick with it - if I really like it and get one I can even order it before I send back the trail one.
I was now also able to install a "Chinese" android market and have been able to find most of the apps there that I want to test - so this is working fine - now to get a VPN working - I always us OpenVPN but I believe I will need to root before that works.
@jabbermacy
As for the Flasing - I would still like some advice on how to backup the device with Titanium for future use.
What do you mean with FLASH CWM?
Would I not be able to backup my device before I do a flash or root?
PS - I have read the forums and it is still not clear about this - some people say you can some say you cant...I am just asking as I think I might get some better answers by asking some more knowledgeable people.
Thanks
i got my 7.7 from Taobao shop like you.
Chinese version is such a terrible thing...

Rollback to all devices that upgraded to 4.x

HELLO ALL,
The OTA 4.1.1 & later 4.5.1 was pushed to Apollo & Saturn (NEW GEN HDX 8.9") Devices adding firefly functionality along with other functionality (WHICH ARE CRAP ACCORDING TO ME)
So in order to get the device back to JB ie.. 3.X version Contact amazon customer services and Say that the Kindle is not working properly after the updates & roll back to the 3.x version.
have the device fullly charged 80% or more and they will initiate a Rollback.
Remember the device will never Get any OTA after this !!
Also it would be a lot lot helpful if some one can locate the ota file downloaded (via ES file explorer) so that we can copy it & share on XDA & help other fellow men.
Also I'd request you to contact Amazon via Phone for Source Code & bootloader info & get the call escalated to higher officials so that there are possibilities of getting info.
I'd request all the devs & members to file a petition (Change.org) with regards to the bootloader and simultaneously work on development
All active members & Ashamed owners of HDX's (Ashamed because with marvellous hardware we have a Crappy OS) include or add devs in this sections via PM or replies so that they can look over this & find a solution soon.
Also I'm thinking that a manual roll back can be done but it needs testing & i need some help in that as well
I believe all the magic is with build.prop & ota.prop that checks the versions.
Interested members can carry on the work here and update the results as well
In the mean time any suggestions are also appreciated
Anyone who will do the rollback, please root device and place file /cache/recovery/last.log (something like that) here.
Thank you.

What will that have?
Give as much as info possible please.
Another observation : As manual update via bin file can be done on Kindle, I opened the file via WinRar & was able to see contesnts as a Zip File so why cant we add su and required root files then update kindle ???
As far as the bin file check is concerned..build.prop edit will work
This give to us name and location of rollback file and some other information about upgrade (downgrade) process.
It is necessary to start somewhere...
About your observation - we can''t flash modified bin in any way.
Btw during upgrade latest firmwares check not only build.prop but keys that located in system recovery. So modifying build.prop is not enough.
Well thanks a lot for the info mate I didn't knew that!!
Just for curiosity how will that file lead. Just need more info about it... I might get that file to you and will that file be even after s factory reset is performed?

Do you have a HDX?
Which one n will there be any problem if I get thor's file? Does it need to be specific?
Can get the file n other stuff within 2 days to you..
Let me also know about keys n. Bin stuff... Atleast point me to some info thread I'll read...
btw a rollback editing bin file worked! I tried to do the same but on 4.5 os now
Any one on 4.3 can try opening 4.5.bin file adding root and then updating...may b can try atleast!?
rollback file is "mod-update-kindle-thor-13.3.2.6_user_713326020.bin"
it is all I know at this moment.
And "NO" again, every editing of original bin corrupts CRC, and file do not pass checking. Do not waste the time. Do you think that no one tried for a year to do it?
Sorry if this is a dumb question but has anyone tried calling the support and asking them to rollback and had success? I just want to make sure that they will do it before I try it
Yes. Guy from my russian forum successfully rolled back after contacting support. So it possible. And he sent me logs of this downgrade in which I saw name of rollback-file - mod-update-kindle-thor-13.3.2.6_user_713326020.bin
Got the Kindle on 14.3.2.7_user_372002520
Unable to root it ! ADB doesn't recognizes device anymore....
I was curious on .bin mod. (Yes i can imagine people trying to edit .bin but i needed an explanation thats it.....)
Now let me know what next !!! ??
How do i proceed ??

HELP.
Can anyone explain me how to downgrade? I got the update-kindle-13.4.1.1_user_411010320.bin and update-kindle-13.3.2.5_user_325001120.bin. But when I try to flash the rom the mentioned way it sais that it isn't possible because there is a newer rom installed. how can I circumvent this problem? Any ideas?
You need to contact Customer Support.
At this moment only they can initiate downgrade.
BTW be careful. Maybe now downgradable version is 13.3.2.7 and its not rootable. But I'm not sure.

What are you looking for exactly?
There's really nothing you can do with 4.1.1 — rooting, custom ROMs, etc. require you be on 14/13.3.2.6 or lower.

Okay, why is that? Is there more information on that? I also read a response from the Amazon support posted on another (German) board which warned about the same thing and that further updates might require help from customer support.... I just don't understand why you loose OTA capability? Even if it doesn't update automatically (which most people prefer a anyway, I guess), wouldn't you be able to just initiate an OTA by clicking on it in system preferences ?
Thanks!
Gave it a go, here is my experience:
I started a chat and asked to roll back to 14/13.3.2.6, the person was happy to help and did not dig into they wy. The steps they had me follow:
- factory reset
- re-register device (was still on 4.5.1 as would be expected)
- they pushed something, I saw a system update in the notify tray but it was only there for a brief moment
- They then had me check for updates
- I told them it did not find anything
- I took a look at my kindle storage and there were 6 nameless files that showed up. When I looked at their properties there was no name or file type on them. I tried to copy them off the device but it would not let me, got a generic access message about not being able to copy the files.
- I was then told that 4.5.1 can not be rolled back and that I should return the tablet for a refund (they did say 4.1.1 can be rolled back). I think this was to be expected based on the "kill switch" code that was found in the new update. I can't find the post/link to the conversation now but I think it was code found in the kernel. Not sure Kill switch is the right term either.
- They are providing me a free shipping label
- Will likely get a 2013 Nexus 7
I'm sorry I'm new to how these forums work and replies and all that. Is there a way to downgrade from 4.5.1 to be able to root? It would be really helpful if someone could give me a straight answer as to if it can be done or not. Thanks!
