Hello guys.
I have purchased U8800 pro two days ago and decided to do some modding here
The phone came with 2.2.2. I managed to root it with SuperOneClick 2.3.
After that I installed CWM 5.0.27 and tried some ICS roms.I liked aurora but I had one problem.When the screen switched off,the phone would reboot after 2,3 seconds....
I recovered via CWM to 2.2.2 and installed the official 2.3.5 rom (build 540g).
I installed 2.3.5 because I have read here in the forums that this rebooting was done because I went straight from 2.2.2 to 4.0.3(don't know if it's true,i'm completely noob).
Anyway,I tried rooting my phone now with 2.3.5 but I can't.
I tried with SuperOneClick(2.2 and 2.3,setted the exploited both to auto and zergRush),with doomlord tool but yet no success.SuperOneClick gets stuck at step 7 and then is says not responding.DoomLord Tool outputs a lot of errors that I don't have permission to write in the filesystem and stuff.
I run both programs with Windows 7 64bit and by right click and run as admin.
Still no success.Tried to restore to factory defaults (with 2.3.5 still there) but yet again the programs don't work).
Of course i have enabled usb debugging,turned log switch one,dump & log turned all on options,enabled non market applications to install....the usual stuff I found in the guides here but still I can't root it.
Also the pink screen no longer works.With 2.2.2 I was able to replace the recovery img and get CWM,but after 2.3.5 the computer no longer finds the phone when in pink screen mode.I also tried all of the above in a laptop with windows 7 64bit.
All drivers installed and updated according to device manager.
Well guys? What can I do? Is is a good idea to try to revert back to 2.2.2 and root from there? I really want my U8800 Pro to have an ICS
Anyway,sorry for the long post.
Hope you can help me.Thanks in advance!
Hi,
I think you flashed the B540 ROM. Flash B512 (yes, you can downgrade; there's no block) and you'll be able to use the pink screen mode (and zergRush will also work)
EDIT: Glad to hear it worked!
Do I follow the same procedure as the one I followed to upgrade to 2.3 from 2.2?
(the step 1,step 2 folders ->dload folder in internal sd with update.app and update_g.app etc etc)?
edit: it seems that the procedure is the same.downgrading right now and I will post the results
edit2: You are the best qwerty12!!!
Thank you very very very much sir!!!!!!!!!!!!! You are awesome! I finally rooted my phone with superoneclick 2.3 and zergRush exploit selected.
Thanks again!
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 ???

Please, me too. I just bought mine too and is rooted, but my cell phones were much easier than the tablets. Either that or I just don't have the patients anymore. Maybe a dummies way to install custom rooms on a500? Lol.

Hi guys welcome to the weird and wonderful world of the acer tab!!!!
Things are very different with this device, whats 'normal' for other android devices is not 'normal' for our tab!!!!
So first of all, dont try installing cwm or a rom the 'normal-this-is-the-way-I-did--it-on-myphone', you will end up with a brick!!!
2nd, you both have working systems at present, so we'll try to keep it that way.
Open up a file explorer and navigate to this:
/sys/firmware/fuse/acer_cpuid
One of the first things that are different is this: acer_cpuid
It should look something like this:
288424344009597 - now u need to add a 'zero' to the front:
0288424344009597 - this is your cpuid, back it up in multiple places if need be, just dont ever lose it - IF anything 'goes wrong' at any time you will NEED this number to save your tab from eternal brickdom!!
3rd once you do get your 'cpuid' go to the 'sbk generator' here.
This generates your 'sbk' or secure boot key and will give you something like this:
0x93588800 0x33CE8901 0x0BED6D03 0x30737899.....
OK then, now you have your cpuid/sbk you can start thinkning about what rom you want to install on your tab.......
Read the OP(Original Post) of your desired rom. This will tell you EVERYTHING you need in order to flash it - remembering always that 'Acer' does not do things the 'normal' way!!!!!!
Most of the custom ICS/JB roms on here all require the 'patched / unlocked bootloader'... In fact, even installing a custom recovery, cwm, twrp or public recovery, for the first time....will require the BL to be 'patched' first....and yes, even flashing this is not done the 'normal' way....tho the process can be complicated there are PLENTY of guides and auto tools to make it easier for you....
The 'patched bootloader flash' will also include a 'custom recovery' too, and you can choose from 3-4 options....amazing but i'd advise to use cwm 1.7.3, until u get up and running, after that you can go crazy flashing anything you like!!
So basically there are 5 main steps to getting a custom rom installed.
1. Install the Acer Drivers and the android_sdk drivers
2. Get your cpuid and generate your 'sbk'
3. Your desired rom is on your external sd card
4. Put your tab in 'apx mode' which allows u access to download mode
5. Install the patched v8 bootloader/recovery - either manually using nvFlash or using the auto tools.
Personally I prefer the manual nvFlash method, if you get an error it will at least give you an error message...the auto tools will just get 'stuck'
Check the 'bootloader' thread OP for a guide to manual nvFlash and the patched bootloader package here
There is also a step-by-step in my sig!!!
If you want to use the auto tools then apxFlash tool, or afterOTA tool you can find both in the 'bootloader' thread. And a step by step for apxflash tool also in my sig....or this excellent one here by user jdgM3NT4L here...
please be sure to read these posts very carefully and if there is something you do not understand then please dont hesitate to ask , there are plenty on here who will help you thru the process....AND its easier to offer help at this point rather than trying to do so when you've bricked it.....
As far as roms are concerned, you cant go past 'civato's FLEX roms' very stable and no issues i'm on cm10 and havent had a problem with it.....Of course it depends on what you require but I'd start with one of the flex ones.
Most peeps here have no trouble with this process, those that do, usually try things the 'normal' way, then find out they need their cpuid/sbk to get out of trouble and of course they dont have it....this makes things most difficult.... there are a few tabs with motherboard issues that have needed to be sent to acer....other than that, he only other issue you may have are driver related, check out the cpuid thread for anything driver related and lots of other background info too....theres also a zip file there that has a mini-sdk kit, to save u downloading the full android-sdk....
i think thats all i can think of at the moment, sorry for the long post and all the caps and bold text - just trying to save you alot of unnecessary grief...
Good luck with it all and remember....in this forum things are not 'normal' :laugh::laugh:
Wow, a lot of stuff to do just to flash a from huh. Lol
Sent from my A500 using xda app-developers app
Lol, as always preparation determines the success of the final outcome....and yeah with the tab 95% of yr time and energy is spent preparing!!! The actual flashing process takes only a few minutes...
Of course u could revert to hc 3.1 where everything is 'normal' i.e. one click root, flash cwm, flash rom, done....
Gosh, even hc 3.2 was locked down and unrootable....
So in the grand scheme for us to even be able to have stable ICS roms, let alone cm10 on the a50x.is.purely down to those wonderfully clever devs we have here..who were never gonna let a.locked bl, get in their way..
OK its complex I'll admit, but stock ICS is c**p and the lives of our tabs extended past wot Acer ever thought....and guys like gersma and.blackthund3r have built auto tools to make things easier
Anyways, its.well worth the
effort and is actually alot simpler to do than it is to describe how to do it...think of.trying to explain how to ride a bike and writing all those steps out....much easier to help them thru it by just getting them on the darn thing and doing it....dontcha think??

Well, I could give u a a d/l link for 3.1 if u really do wanna go back....but I think gersma's afterOTA tool can do it too, tho I've Neva used it for that so can't really comment....
Oh, one other thing, you'll wanna back up all yr personal stuff, music, photo's and wot not especially going from one build to another, and most of the custom ROMs require a complete wipe and format of yr data partition too before install, just so u know!!

wow dibb, thank you so much for a helpful response!! Really enlightened me about how far off I was about the update process (compared to updating phones) and yet close enough to what I had to go thru for the Viewsonic GTab.
I'm currently on stock 4.0.3 rooted for A500. I have obtained my cpuid and SBK. When I go to recovery mode, I see a droid with triangle and exclamation mark. I tried flashing twrp but I still saw the same droid. I now know that I need to flash a different bootloader with recovery included.
My question is that if I flash the new bootloader which will allow me to put a custom recovery, during that process will my current ROM be removed or wiped out? If so, what do you recommend for backing up the app in the current stock ROM? Titanium Backup? BTW, I don't have an external SD card; all I'm using is the internal 8GB
Thank you for your help!!
def need external SD , it will help out alot

Yes u need the v8 bootloader to get a recovery installed...
Always check the original post of the rom you install for special instructions regarding bootloaders.....this applies to all custom Roms even stock pre rooted ones.
Yup TB to back up yr apps and data - dont restore immediately...make sure everything is stable first.
If u dont have an ext. SD card, the EUU method doesn't require one, and as slayinu said, it would make it easier if u had one especially for the update.zip methid
Im sorry...
I have the a500 running ota 4.0.3....well from the official app. I have it rooted and running superuser yet I downloaded the Acer recovery installer app from the market and get the recovery verified failed message when booting into any custom recovery and the dead android with the exclamation mark....I know I need a patched or an unlocked boot loader but I cannot find one I downloaded the afterota but it doesn't do anything on my computer...idk what to do the frustration is gonna make me break this thing and just go buy a newer tab running jb ....help please!

Seems weird afterota "doesn't do anything"...did you install the drivers?? Did it give u yr cpuid/sbk you cannot do anything without this AND if u muck things up its the only thing that will get u unbricked? Are u using a micro USB cable? Do u have USB debug enabled?
If u go to the root guide in my sig you'll find d.load links and all the guides to help u install the v8....take special note of the boot.p file u need to rename or delete in /system....
For more info on getting yr cpuid/sbk see the cpuid guide in my SIG or the sticky in dev forum...

obviously..
I'm too dumb to figure this out...idk how to get my cpuid none of the ways in your "where's my cpuid"guide worked.I don't want to stay stuck on ota 4.0.3 but apparently I have to..thanks for your time and your advice,unfortunately I wasn't able to use it properly.
Well, it seems it's not just you being dumb ...
I tried the same - original OTA 4.0.3 and rooted my A500. Now tried to use the 'AfterOTA'-Tools, but getting stuck in step 3 of 4 (maybe i just need to insert a SD-Card in the Tab?).
Just got no idea, what to do now - the only thing i know is: before flashing, i need a open bootloader, but i've got no idea how to do that. The Guide linked in this posts: http://forum.xda-developers.com/showthread.php?t=1622425 is just confusing me more and more
After a reading a few times, it seems to me, that MY next step should be:
"Automated flashing tool" (STEP 5= Going into APX mode see Q&A or use A500 manager)
-1-Reboot your tablet and make sure on your tablet: "Settings" -> "Applications" -> "Development" -> "USB debugging" switch on.
[...]
-It will ask if you are ready (click yes if you are)

Hi voodoo, no, neither of you are being dumb!!! It CAN be a complicated procedure, we try to make our guides 'simple' but theres ALOT that can go wrong
Yes the last link you posted will flash the patched bootloader!!!
- but basically this is what SHOULD happen
Note: The only way to get a custom ICS rom on your tab is with the v8 bootloader by skrilx_cz. This must be flashed via nvFlash/apx mode.
Note:The only way to install a custom recovery like cwm or twrp etc is with v8 bootloader.
Note: You cannot use Acer Recovery Installer unless you have the v8 installed.
Note: Rom Manager does not support our Acer Tabs...please don't use it to flash 'anything'!!
OK heres an overall view of the process:
1. Install Acer and adb/fastboot drivers
2. Retrieve your CPUID...
3. ...and use it to generate your SBK
4. Download your ICS or JB rom and copy to your sd card (internal or external)
5. Enter apx mode to begin the flash!!! or use apxFlash tool
5. Use balckthund3rs apxFlash tool and follow the instructions: hint: dump and save your bct!!!
5. If using civato's manual nvFlash method - Put your tab in apx mode and run the .bat file
5. AfterOTA Tool is only for those tabs which have OTA'ed to ICS!!!
The main issues you will have with the actual flashing process itself is a partitioning error or a bct error - and both of these are easily fixed...UNLESS your tab in one of the few with a hardware fault which only a new motherboard can remedy
Once you get the big white "PASS" on your tab, boot straight to your new custom recovery, do the FULL WIPES and flash your new rom....DONE!!!
Well ... i now used AfterOTA - but not in a virtual machine - now just natively installed on my macbook via bootcamp (windows). Worked. I now have a V8-Bootloader (the tab shows me this when iam booting it up).
Whats the next step to flash a new ROM? Iam ready to do that? Or is there any other step needed by now?
Regards, Tom
Edit:
I now just tried flashing a custom rom - so i copied the *.zip to my USB-Stick (FAT32) - because i read, i can use an USB-Stick as an micro-sd card.
Tried booting into recovery-kernel - worked for me, but the only thing i can see: a lying android with an red sign ("!").
Did i something wrong?
Oh dear....if u had a stock rom on there then its overwritten
your newly flashed recovery....you need to delete or rename
the "boot.p file" in /system..then reflash the v8...
The very next step should be to enter recovery and flash your
desired rom....
So, it now just works everything.
Used Acer Recovery-Manager to re-flash the recovery - worked fine for me.
But: i tried several 4.1 and 4.2-ROMS ... is it correct, that there's no Google Marketplace anymore on 4.1 and 4.2?

Hi @MidoTayel i have also bought a Lenovo a3500-HV less than a week ago i know of two goo tools that can help you root they are:-
Farmaroot- http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276
ROOT Genius- http://www.shuame.com/en/root/
But i would recommend that you WAIT A FEW DAYS as you know that after rooting the system can get corrupted (Based upon the app you install) thus you would send it to the service center and they would charge a lot of money(root void your warrenty). Apparently i am researching how to create and flash scattle files (Backup images of all system files,recovery.img,boot.img........) in Lenovo a3500-HV(Companies use this method to install android after the tablet is made).
Also i am researching how to create a clockworkmod recovery which will help in flashing updates and flash.zip modification and will also create nandroid backup of your entire system
If you can wait a few more days (5-6) days i will email you a set of tutorials from backuping imei numbers to creating scatter files(Right now i am sorting the best tutorial and good information from the junk in the different forums and blogs). With this information you do not need to go to the service center for any software issue anymore all you would need is an computer and a OTG cable (the cable used to connect phone to computer) and if you install custom recovery you would not need that also (Saved over Rs6000 in my previous tablet software problems)
I am also planning to make a thread upon the LENOVO a3500-HV
Also i have a few QUESTION i want to know if you are facing these problems as i want to know if it is only in my tablet or the entire firmware
-Does the tablet restart between every 4-5-6 hours
-The GPS does not work Test using GPS TEST app ( https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en ) Already found some fixes but it needs root
-Can you boot into recovery mode or does it get stuck in the boot logo
-Can you install CPU-Z ( https://play.google.com/store/apps/details?id=com.cpuid.cpu_z&hl=en ) and check if the hardware is the mt6582 model (Picture given below)
LAST of all can you give me your email id as yau are the only other Lenovo A3500-HV (Model is new) member i could find and i will first email all the tutorials i.e. doc,vedios,pdf to you and help you through email and chat
And if you only want to root and don't care it goes to the service center please atleast tell me if the root is working or not THANL YOU

ROOT Genius- http://www.shuame.com/en/root/
But i would recommend that you WAIT A FEW DAYS as you know that after rooting the system can get corrupted (Based upon the app you install) thus you would send it to the service center and they would charge a lot of money(root void your warrenty). Apparently i am researching how to create and flash scattle files (Backup images of all system files,recovery.img,boot.img........) in Lenovo a3500-HV(Companies use this method to install android after the tablet is made).
Also i am researching how to create a clockworkmod recovery which will help in flashing updates and flash.zip modification and will also create nandroid backup of your entire system
If you can wait a few more days (5-6) days i will email you a set of tutorials from backuping imei numbers to creating scatter files(Right now i am sorting the best tutorial and good information from the junk in the different forums and blogs). With this information you do not need to go to the service center for any software issue anymore all you would need is an computer and a OTG cable (the cable used to connect phone to computer) and if you install custom recovery you would not need that also (Saved over Rs6000 in my previous tablet software problems)
I am also planning to make a thread upon the LENOVO a3500-HV
Also i have a few QUESTION i want to know if you are facing these problems as i want to know if it is only in my tablet or the entire firmware
-Does the tablet restart between every 4-5-6 hours
-The GPS does not work Test using GPS TEST app ( https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en ) Already found some fixes but it needs root
-Can you boot into recovery mode or does it get stuck in the boot logo
-Can you install CPU-Z ( https://play.google.com/store/apps/details?id=com.cpuid.cpu_z&hl=en ) and check if the hardware is the mt6582 model (Picture given below)
LAST of all can you give me your email id as yau are the only other Lenovo A3500-HV (Model is new) member i could find and i will first email all the tutorials i.e. doc,vedios,pdf to you and help you through email and chat
And if you only want to root and don't care it goes to the service center please atleast tell me if the root is working or not THANL YOU

Thanks for reply and that's my email [email protected]
GREAT !!
I finally found other guys having Lenovo A3500-HV
@MidoTayel
I guess you can use vRoot to root this model of lenovo (A3500).
But as @anandisrocking007 mentioned, I also recommend that you wait. Because the root may be dangerous without CWM recovery to make backup image of your system.
@anandisrocking007
I am happpy with your researching and waiting you…
I have some answers of your questions:
1- My tablet doesn't restart automatically ever from I bought it.
2- You can boot into recovery mode by holding the three buttons together (Vol. up + Vol. down + Power) after shutting down the device.
Other problems I will check them later.
Thanks.

Hi @ibraheem_alex so the USSD anomaly is not only for my phone its ok not to worry i am 95% sure that lenovo does not have locked bootloader also did you check the GPS is it working also use CPU-Z to check the chipset model mine is MT6582 when everything is over i would be uploading the scatterfile backup for everyone to use i just want to know if more than one type of model is released as different countries have different chipset but the same model (Pss..It won't have an impact on the tutorials that i shall post as you shall make a backup of your own phone :highfive
Tutorial Update- i have managed to download some vedios from sites and found a lot of tutorials that i have saved in .docx format just 1-2 more sites are left i shall then sort out the best one and if require will merge some to make a better one all and all i shall post it within a few days the tablet is an huge investment i think its fine to be a little patient....... (Pss...i shall be uploading it in google drive and will publish the link...:good

Hi @MidoTayel let me put this in simple words take windows for example where there is a guest account and there is a admin account in guest you can use the software but can not write anything in the C Drive(Also can't install software which are stored in C Drive) in that way Windows's C Drive=System Partition on android so when you get a phone its always in guest mode when you root it it gives you admin access. Some apps require to write or change file for it to work eg ROMtoolbox , Xposed module etc when you are not rooted the apps save all files into the data partition and if any problem occurs you can do a factory reset (i.e deleting the data partition) and it will be the same but if you are rooted and have some problem in the system partition even factory reset won't it goes to the service centre and they charge. Scatter file backup and nandroid backup are ways to backup an entire android OS ie system,data partition along with others its like you are creating an entire android installation setup and when your phone is bricked you can reinstall it. Overall i can tell you that the privilages of root outweigh the risk a lot what every you do try to research a little (I took 2 months to root my last tablet) and always make a scatter file and/or nandroid backup as soon as you root (First backup then check the cool device i.e ASAP) you root to be 100% safe
I am making tutorial to hep you root or create a backup....
Hope this helps i was confused for weeks thinking what is root when i started android..hope you don't face the same problem
PRESS THANKS IF IT HELPS.....:victory:
My chipset model is MT6582 .. It is same as your chipset.
I couldn't determine if my GPS working or not...
I used the GPS Test as you mention but also I can't know if it working correctly or not .. May I will make another test while moving in car.
But I captured this photo from the app .. May it help you.
See the photo in attachments.
Hi, I have a model A3500-FL (without back camera).
GPS works, locks in about a minute out in the open. Tablet lacks AGPS (no data connection). It's MT6582 which can use Mediatek's proprietary EPO to speed up positioning, but due to no root I cannot verfy if it is working or not.
Anyone tried backing up A3500 via SPFlash or MTKdroid tools or rooting?
Hey i wanna install the kali linux on my tab so if there is other way to do it without root it pls tell me
Hi
Me to .. I need to run Linux Ubuntu on my tablet.
But I think NO way to run linux without rooting your tablet.
This is how I rooted my A3500-FL under Xubuntu 14.04 (i have win 7 in VM):
1. install Virtualbox, not the OSE edition - get the full version from Oracle website and also the extesion pack (it enables direct access to USB devices)
2. Install windows (XP or 7, don't know about later versions)
3. Grab a copy of RootGenius from here
4. Enable usb debugging on tablet Connect your tablet via usb, make sure it is recognized by ubuntu, there is no need to mount it
lsusb for my device:
Code:
Bus 002 Device 004: ID 17ef:7738 Lenovo
5. Start your windows installation and mount the USB in virtualbox (there is a button for that at the bottom of a windows running your VM), make sure windows sees your device, it will probably fail to install the drivers
6. Start RootGenius, it should download and install drivers for this phone. Tutorial including usb debugging here. Click root a wait for a minute. Done
If yu are running windows skip steps 1-2.
Optional: make full system backup here
I did a backup before rooting. MTK tools somehow sneaked su binary past the android defences and got shell root after backing up.

How did you upgrade? OTA updater shows me only some minor version upgrade.
Greetings,
I wrote this tutorial to help all the people strugling with their A500 , to unlock the bootloader , install custom ROM and root it since I've finaly managed mine to work as I wanted it to. All the links / threads that I've posted are active and DL links are working.
Note : Below is going to be text in italic , just to show what I've been through and tried at the begining of my post , seeking for help , before I managed it to work for me at the end.
Before you start linking and re-directing me to other threads, I have read many threads on here that have instructions etc... but the problem is that 80% of the links from stock rom's , flashers , recovery's don't work because most of those links were created in 2012,2013.
What have I tried :
- rooting via ICS_rooting_A10x_A5xx thread ; couldn't get full root
- installing stock OS from Acer's website via SD card to get recovery menu back ; unsuccessful
- Acer Iconia A500 Tools by blackthund3r ; It only detects A500 in APX mode , but it says install driver's which I already have.
Currently running : ICS 4.0.3 with corrupted recovery menu and unsuccessful root
I would be very happy if anyone could help me and firstly return my A500 to full stock (full wipe via recovery menu), and from there start the procedure of rooting , unlocking bootloader etc... and supply me with working links to tools, roms and flashers. Everything step by step.
Thank you very much for help in advance.
Best regards,
Domitri from Slovenia :fingers-crossed:
Update - Bootloader ; OLD FINDING
I got to a point where I realised that my bootloader is locked. I've tried unlocking it via fastboot commands from the following thread : forum.xda-developers.com/showthread.php?t=1514951
I tried : " fastboot oem unlock" and "flashing unlock_critical" but 0 result, I ended up getting a small red text error on my tablet and I would have to start all over. I typed "fastboot oem lock" just for my interest to see what would come up and I got this , just like in the original thread : "Fastboot: Device is already locked! Abort ..."
I am going to try and unlock the bootloader via some run.bat option from APX mode ; I forgot where I found it (going through too many posts , going to post afterwards).
Note : Everything that I try, and if it work's for me, will be uploaded to my dropbox and will post a link with detailed instructions on how to do it, just bare with me please
Its hard to find working files / DL links for this tablet from other threads because everything is from 2012,2013 mostly.
START OF THE TUTORIAL
Note : Before doing anything , if you tried unlocking the bootloader and rooting and it was unsuccessful, I suggest you reinstall the OS via update.zip from SD card in recovery menu, so you have a fresh start and also install the drivers that I have provided, that way my steps and procedures will work 100%.Be sure to scroll down to the end of the thread to check for any new updates. If you have any questions or you ran upon a problem, feel free to message me or comment
MEGA LINK - ZIP FILE CONTAINING EVERYTHING YOU NEED - SEPERATE LINKS TO THE FILES ARE POSTED BELOW : https://mega.nz/file/IAIhUAzT#KNGqIG7ReTlRcuBXHwFiEcY4CAz3xZsKjzVXhhSc6MU Credits & big thank you for all the post's , help & files : KaijiKun , Civato , Blackthund3r , Vache , Turnert , Dibb_nz , Mlopik , Jm77 , Chainfire , Skrilax_CZ
USB drivers : https://www.dropbox.com/sh/6lx3uxwhj5zxbbm/AAAbhxcPTNSFX7Z0A3t3z93Pa?dl=0
In the drivers folder in dropbox you have 2 installers for ADB, if one doesn't work for you you can try the other one. "UniversalADBDriverSetup" worked for me.
In the folder you also have 2 APX drivers , one is from Nvidia and other is Universal Naked Driver 0.73. Universal Naked Driver worked for me.
You update the APX drivers via device manager.
optional Android Multi Tool : https://www.dropbox.com/s/s7ypank8oijwwry/Android_Multi_tool.zip?dl=0
In the MultiTool folder you can SHIFT + RIGHT CLICK and open a Powershell command window , and then write "adb devices" to check if you installed ADB drivers properly. If you did , you should see your device serial number pop up.
Make sure you have enabled USB Debugging in settings under Developer settings on your A500 !
How to bypass driver signature enforcement in Win10 : https://www.windowsreport.com/driver-signature-enforcement-windows-10/ - needed for updating the APX driver
or in other words, how to forcebly install drivers when windows doesn't allow you to install them.
STOCK OS 4.0.3 ICS : https://dropbox.com/s/djblya5kol2cp4a/A500-Stock.zip?dl=0 thanks to KaijiKun
Rename the zip to update.zip and apply update from sd card in recovery menu. If you have a corrupted recovery menu like I had, this is what you do :
Press the volume down button (the one closer to the power button to the edge)
Press the power button for 2-3 seconds and let go
Keep holding volume down button until small white text pops up in top left corner of the screen.
This procedure will also get you into recovery menu (if you have a working one)
1. BOOTLOADER
Before you start unlocking the bootloader , you will need to get your CPU ID which we later convert to SBK needed for flashing the bootloader.
I have managed to obtain CPU ID number by the following steps :
Install File Manager+ on A500 (or any other file manager) ; link to File Manager+ : play.google.com/store/apps/details?id=com.alphainventor.filemanager&hl=en
Make sure you have ticked to see hidden items in settings
Go to : System /sys/firmware/fuse/acer_cpuid and open as text with HTML Viewer (best option)
OR
With File Manager+ navigate to System /mnt/external_sd/dmesg.txt
Long press on the dmesg.txt file and share it / send it to yourself via mail
Open the file on your PC and CTRL + F (find) the word "androidboot.serialno" , that is your CPU ID.
That 15char number is your CPU ID (example : 37c7084407fb2d7) which you can convert to SBK number with SBCalc.
You should get something like this at the end : 0x16796E00 0x88991201 0x67D0F603 0xC2DD2003
Sometimes there might be a 0 infront of your CPU ID , just delete it.
Note : Copying my CPU ID / SBK will not work , every tablet has It's own unique one.
SBCalc : https://dropbox.com/s/g4ay6hfvym1jxwy/SBCalc.zip?dl=0 thanks to Vache
originaly from this thread : https://www.forum.xda-developers.com/showthread.php?t=1810618
Now when you extracted and got your CPU ID and SBK , we can start with flashing the bootloader.
Nvflash tool : https://dropbox.com/s/jecamd2w91nx3k7/A500-Bootloader-Nvflash.zip?dl=0 thanks to KaijiKun
Extract everything to a new folder on your desktop
Replace the recovery image(recovery.img) inside the nvflash folder with this one : https://dropbox.com/s/0gd9jhi8ufzhpbc/update-recovery-TWRP-rev2.0-beta4.zip?dl=0
Inside the folder you will see a HowTo text file , open it and just follow the instructions.
After you ran A501 A.bat , power off your tablet , and go to recovery mode - Volume down + power button then release power button after 3 seconds while still holding volume down. If it doesn't go directly to recovery menu by TWRP , select "BOOT RECOVERY" from the green menu
Follow the instructions from HowTo.txt to wipe the system
Power off your tablet , unplug the USB cable and put it in APX mode again. When in APX mode, reconnect the USB cable
Run A501 B.bat and enter your SBK again
When everything is completed both when runing A and B bat file you should get "PASS" written on your screen , dont mind if you get any small red text below that.
2. INSTALLING CUSTOM ROM
Now after we unlocked our bootloader and installed TWRP custom recovery, It's time to install our CUSTOM OS / ROM.
https://forum.xda-developers.com/iconia-a500/general/2018-a500-upgrade-threaddownloads-to-t3832293 thanks to Turnert for the post and Thor2002ro for the ROMs
In this thread linked above you cant find 4 different ROMs , for me every single one booted, but I couldnt get gApps (Google Play and Google Play Services) to work with any of them , Google Play surely will open, but when you will try to download anything it will pop up an error.
If gApps dont work on custom ROM , you can still download and install APK's from the browser and use them normaly.
The only ROM that worked for me the best and most stable with working gApps is Tegraowners 4.4.4 : https://www.dropbox.com/sh/lv2u88kjnzajcb5/AACW8iKYARd-zHgK9_w4DDgCa?dl=0
In the link above you will find both the ROM and working gApps.
You download the rar file of your chosen ROM
Copy the zip file / files to your SD card
Boot your tablet into recovery mode. From the recovery menu hit Install and then navigate to external_sd folder.
Click on the zip file in the folder / SD card and swipe to begin installation
Go through installation
After the installation of the ROM , install / flash gApps
READ THE TUTORIAL BELOW ABOUT FLASHING ROOT - SUPER SU BEFORE EXITING RECOVERY
If the installation of the 3 things was successful you should boot into your custom OS
Note : The first startup always takes alot longer - several minutes , after the first boot, the booting time will be alot faster
3. ROOT - FOR CUSTOM ROM
Download SuperSU version 2.82 from the following link : https://download.chainfire.eu/1220/SuperSU/ thanks to Chainfire
Install it in TWRP custom recovery after you've installed your custom ROM and gApps.
4. ROOT - FOR 4.0.3 ICS USERS ONLY
Blackthund3r tools : dropbox.com/s/58g5v2x0lwg8mab/Acer Iconia A500 Tools by blackthund3r.rar? thanks to Blackthund3r
I have somehow managed to root my A500 with ICS Root 7.2.0 tool , altho it was saying in bottom left corner that there is no A500 connected with debugging. I went and give'd it a shot without knowing it's gonna work , and my tablet restarted and I was suprised, checked root with 3 checkers, and looks like it is done.
Leave everything as it is ticked , only the last 2 items should be unticked - "Disable AcerNidus" and "Don't reboot after installation"
Note : Even if your tool says "No A500 with USB Debugging Detected!" , ignore that and hit "DO IT" button, it works anyway !
If your root was successful , your tablet should reboot about 2-3min after hitting "DO IT" button and instead of "DO IT" you should see "DONE"
Check your root with Root Checker Basic : https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck
Because there is a older version of SuperSU installed, and you cannot update the binary when you open up the app on A500 , you need to download and install a newer version by yourself.
SuperSU 2.82 https://androidapksfree.com/supersu/eu-chainfire-supersu/ thanks to Chainfire
Download the APK from your browser on A500 , and install it. You will be prompted that this will replace an existing app - hit ok.
Note : Be sure you have ticked "Unknown sources" in settings under security tab !
When you have installed the APK, open it up. It will prompt you "The SU binary needs to be updated. Continue?" ,hit continue and choose "Normal" installation of the binary.
I hope I helped you with this tutorial, but if it happens that you're stuck somewhere, just send me a private message and I will be happy to solve the problem with you.
UPDATES
22.3.2020
I noticed after using my tablet on IconiaHD ROM that gApps stopped working , and I'm getting error at all times that google play services stoped working and it's annoying because you can't use your screen at all because it's poping up all the damm time.
I tried and flashed my A500 with this ROM - https://forum.xda-developers.com/showthread.php?t=1520299 Lightspeed 4.8 The download link for the zip file from google drive is still working, so there shouldn't be any problems with downloading the rom.
Next thing I did, I read that it works best with custom kernel from @ezterry from the following link - https://forum.xda-developers.com/showthread.php?t=1703590 (download link still working inside the thread - ezT20-v1.0.1-a500_S.zip ! )
With this kernel you can overclock your tablet to work smooth , I'd say min and max value to 1408mhz or 1504mhz. Flash your tablet with kernel from your SD card after instaling Lightspeed 4.8 ROM.
I've also read that for all the outdated apps in google play, there is a little trick with the following app - https://www.dropbox.com/s/4t29ux4h20u60do/market-helper-2.0.4.apk?dl=0
It's called market helper and what it does, It shows your A500 to google play like Samsung Galaxy S8 or something similar which can run most of the apps on the market , and with that you shouldnt have any problems with ICS being too old for some apps.
25.3.2020
I've been testing all the ROMs I managed to find for A500, and the one working the best, being the most stable and having useful / non-crashing gApps is Tegraowners 4.4.4.
ROM and gApps : https://www.dropbox.com/sh/lv2u88kjnzajcb5/AACW8iKYARd-zHgK9_w4DDgCa?dl=0
Flash the 2 items from the folder with procedure I have written above in the tutorial section. I also updated the tutorial and replaced old download links with working rom link. THERE IS NO NEED TO FLASH AFTERWARDS WITH EZTERRY'S ROM !
The ROM is working perfectly when overclocked to 1504mhz settings. No need to be afraid that you will burn your tablet CPU, I have tested it , and I've also read in other threads that some users OC to 1646mhz. When OC'ed its very fast, snappy , no lag or anything.
If I will experience any problems with this ROM I will post about it / post a fix if I will find any.
Note : The market helper apk from previous (upper) update is showing up in Google Play devices when you set it up, but it isn't installing apps when you select install , so that a no go
27.3.2020
A way to stop Google Play Store from getting auto-updated / corrupt. When you download a newer app that might be downloadable to the tablet , it auto updates Google Play Store to the newest one in the background because the app itself needs those requirements so it can run. When it updates, it's corrupted because it doesn't match with gApps (services) version number.
If your Google Play Store updated already by itself, go to : Settings > Apps > Downloaded (first thing that will open) > Google Play Store > Uninstall Updates and Replace with factory version
Turn off your wifi
Open up terminal emulator
In the terminal type :
Su (then grant access if asked by SuperSU)
Type in : touch /data/app/com.android.vending-1.apk
After that type in : chattr +i /data/app/com.android.vending-1.apk
That should prevent Google Play Store from auto updating and being unuseful
I've also found a link for Chromium , optimized for Tegra devices (which A500 is) : https://forum.xda-developers.com/ga...t/app-chromium-m56-optimized-tegra-2-t3550210
When you will install everything, turn off auto updates in google play, because if you update the GPS app , after the update you will be getting an error every second on the screen saying "GPS is not responding / has stopped working" , and tablet will be pretty much unusable.
FOR ALL THE QUESTIONS DON'T HESITATE TO MESSAGE ME VIA PRIVATE MESSAGE OR LEAVE A COMMENT UNDER THIS THREAD , I WILL BE MORE THAN HAPPY TO HELP YOU !
I am struggling for days trying to root/update a500 with 4.03 installed. I am going through the same pain as you had with so many dead ends. I will try your recommendations in your tutorial in the next few days. Hoping it will work for me too.

Hey,
thanks for commenting ! I had waaay to many dead ends, but finally managed to get it working as I want to. Just follow my steps and you should be OK , if you need any help feel free to comment again or send me a private message
Everything worked perfectly fine. My a500 is finally rooted and running a custom rom. Your instructions were so clear and easy to follow. I can't thank you enough for this tutorial and all software/drivers/tools that you provided. I spent days trying to find working links for some of those tools.
Domi, hats off to you.

Greetings !
Im glad I was able to help you with my tutorial. Yeah at first I was looking like crazy around for drivers and working tools , and when I figured out its not easy to find all this stuff, I decided to put up a tutorial and upload everything to my dropbox, which will always be available to download.
Best regards,
Domitri
You can use magisk with the a500.
The only stipulation is that it cannot flash the boot image and you have to manually patch it (via the magisk app itself) and flash it via computer (there doesnt seem to be any on device flasher that ive found. flashify and flashfire do not work). It's a good idea to have the rom's boot image on your device so that you can easily patch in magisk when there's an update, and the patched file should be in the Downloads folder.

Hey ! Have you installed all the drivers that I provided in my tutorial ? They are key for the whole tutorial to be working properly. Sometimes in apx mode, my PC also doesn't recognize the device, but you must keep proceeding with steps , because they will work. Dont mind your windows not recognizing your tablet, it will do that 70% of the time.

For Spotify I think you just have to install an older version. Probably at least a year back.

Most apps don't work because this tablet does not support something called neon I don't know exactly what it is but it seems to cause a lot of the combatiblity problems with this tablet also the tablet is 9 years old so you just kind of have to expect things not to work.

Search on www.apkmirror.com for Spotify or just type into google Spotify apk 4.4.4 and I'm sure you'll find it

That's wierd, most of my apps work normally and I didn't change anything special. I just dont update the GPS app because it ****s it up afterwards and you'll be getting error messages about GPS not responding / stopped working like every second.
just passing by and want to thank you for this great post.
I had an idea, it would be nice to list the apk version numbers that works on our tablets, i mean Spotify version number 4.4.4 and so on with another ones.
Again, thank you !!!!
Hello !!

Thanks for the compliment. Basicly there is no need to do that since everyone needs differend apps and its very easy to find it on apkmirror's site , I belive that it is compatible from 4.0 to 5.0 my guess, but the best way is to stick with 4.4.4 versions of APKs.
