I have a problem. Trying Alexandra rom for Acer A500. But ran into an issue.

It is stuck on Acer Screen.

Running bootloader 3

Coming from Thor CM9 rom.

Wiped all exactly how it was posted in first thread.

Was able to reinstall, but still have same issue. Thinking maybe a kernal issue since I have a modified one on there.

I am not sure what to do.

Did search all through the thread for a solution but couldn't figure it out.

Please help.
[Acer Iconia A500] Moscow Desire:
Yeah, coming off Thors rom can be a real pain as I've read. Not exactly sure why but a lot of users have the same issues.

Ok, I really can't help you on this, as I'm not really sure which direction to go. :confused:

For starters, which recovery are you using? And which version is it?

One of the things you could try, for example, is installing EZTerry's Public Recovery (for ICS) and try wiping. formatting and install the Alex rom.

Sometimes different recoveries wipe better than others. (no joke) Also, if you're using an older version of CWM you should try updating. Right now, I run CWM 1.7.3. (too lazy to change)

Ver 3 bootloader?........wow.... Personally, I would update the bootloader. Ver 3 was good, I know it's a pain as Skirlax didn't incorporate the bootloader zip flash till after ver 4, but still.

So for starters, update bootloader and update your CWM. That might do it.

HA HA HA!!!

Actually Siberia is pretty this time of year :p

In reality, we don't even have 501 ICS kernel source yet, so the chances of getting 3g and gps working on Jelly Bean is almost impossible. They are working on JB right now (Paul and Scherer), for the 501, so maybe they may come up with something. Will be difficult without ICS source.

I'm on Alex_V_Version_1_4 & I have very frequent incidents of 3G drop then a No Network. I always have to reboot to get back network & connection. Is this fixed on ver1.4 final ?
[Acer Iconia A500] Moscow Desire:
Well, in the OP, it states it "may" be an issue. It effects some tab's more than others. It's due to it being a "release candidate" and not an official release. About the only thing to do, if it's critical to have 3g all the time, is to install the WakeLock app from the market. It prevents the tab from going into "deep sleep", but it also uses your battery a lot faster. And I mean a lot faster.

Right now, I'm testing the newest Acer update (still not an official one). In almost 2 days, I haven't lost signal, and it always wakes up from sleep. Galapagos1 has been running it for a day longer, and he hasn't reported any loss of 3g either.

It's still too early I think to call the issue fixed with the build I'm testing. The last time, it took over 3 days before Alex 4 started dropping 3g. But it looks promising. Today, it worked fine, even when I lost signal in the metro, it came back both times.

I will try to get a testing build out later today. Tomorrow morning at the latest. Let you guys test it and see what you think. Right now, it's full origin odex, so no battery mods, and also Acer ring doesn't work from the taskbar (no surprise there). Personally, I think the app drawer works smoother with Full Odex, in comparison to De-Odexed.

[Acer Iconia A500] galapogos01:
No worries bud. I didn't wipe battery stats, but I don't have any crazy apps chewing battery. betterbatterystats tells me no unusual wakelocks. I'll give it a few more charges before I make up my mind, but so far its worse than the last leak :(
[Acer Iconia A500] Moscow Desire:
That's really strange. ??? I've been up for 7hr 43 min, on 3g only, and still have 87% and was at 97 when I left home. (didnt have time to charge it all the way).

Of course i have it pretty well stripped and no synchs running.

Open Testing​

EZTerry ezT20-v1.0.1 Kernel for a501 ONLY

75728d09deda8b1f1f42346ca8ad59b6 *ezT20-v1.0.1-pre1_S.zip

ICS Only

*** 1.5ghz OC

*** UV control

*** Full Sys RW

*** GPS Tweak

*** IO Tweak

*** BFG IO Scheduler

*** lulzactive CPU Controller

For installation, Flash via CWM, Public Recovery.

Download a CPU app from the Market. I use System Tuner, but any should work.

Note: This is a TEST kernel. Battery life doesn't seem to be the best, but could be because of Google Now (GPS/Wifi running)

I shouldn't have to say this, but make sure you do a recovery backup before flashing.

Acer_AV041_A501_1.021.00_WW_GEN1 ICS 4.0.3​

Rom based on latest Acer leaked update.

Note: With this ROM you need to run Zero-Null's root after installation. Set your USB Debugging to on. Ignore the errors just let it finish rooting., Then use Root Explorer or File Manager HD to set the /System to R/W.

Thanks to:

Galapagos1-System Dump

EZTerry - Custom Busybox install

Details;

Full Origin ODEX

Newest Busybox

Includes ALL Acer Bloatware

Things to specifically watch for;

3g for dropping

SOD

Battery Life

Installation is the same with my other roms. If you don't know how to install a rom, please see the instructions in the Original Post. Example: Wipes and Formats

You must be on the unlocked ICS Bootloader for this rom to function properly

DOWNLOAD

Enjoy!!!! Remember, this is a STOCK ODEXED Acer build. I am not responsible if games and restored data do not function well. Although I did add the latest Busybox and custom install. Also, I used slight compression in the zip, as Acer seems to want to overbloat the rom where I can't find a server to upload. But it installs fine on my tab.
[Acer Iconia A500] tosomax:
really like :D
[Acer Iconia A500] yassero:
if I do (from Post#1):

Go to Mounts and Storage

a. Format System

b. Format Flexrom

Will this wipe my internal SD ? my titanium backup folder lies over there, do I need to move it to the SD Card ?
[Acer Iconia A500] Moscow Desire:
No it will not. It will format /System partition and /Flexrom partition only. Your /data/media area is safe. Technically, the rom install itself also is set to do this, but I like the extra formatting.

Of course it is advisable to do a recovery backup before installing "ANY" file.

Now, there are lots of formats in the menu, so make sure you do only system and flexrom.

All you need to do, is just follow the basic install for CWM. After boot, use a file manager to set /System to R/W for full access.

I have TWRP v2.1.3 recovery.....it does not have that option......will it affect if I flash with out doing it ?

Edit: I flashed Ezterry's BareBones Recovery as I have seen it on your signature......now ROM got flashed......will test & feedback
[Acer Iconia A500] Moscow Desire:
I haven't had a chance to use TWRP yet, so I don't know how it works. But EZTerry's should work good for you.

Just a word of caution. Be careful which versions of recovery you flash. Lately I have noticed there are several versions available, both for the old Honeycomb Roms, and also ICS. Just be sure the recovery you install is for ICS, and you should be ok.

Been running Evil test for abt 4h, everything is fine. Tks MD :)
[Acer Iconia A500] Moscow Desire:
Thank you sir! Just keep watch on those 3 things. With the last build (.014), it took about 3-4 days till I noticed things.

3rd day, all is well. Lost 3-4% overnight on battery (8hrs). Wifi and full Google synchs running. GPS off.

Today, about 2hrs web surfing (took baby in park). Lost 9-10% running 3g only. GPS off.

Overall, I'd say not too awful bad.Could be a little bit better during use. But maybe that will come when we get an undervolt kernel in the future.

Hi Moscow i am with alexandra III rev.1.1 HC bootloader yet . do you suggest me to change with this?
[Acer Iconia A500] dxjak:
I have been running it since last night installed it with full battery. after install, left it on 3g, I have whatsapp running and a lot of emails comming in and since about 10 hrs I am up to 72 % GPS is amazing, it is very strange to be able to use my A501 to the fullest without having wakelock draining my battery.

thank you so much MD.
[Acer Iconia A500] Moscow Desire:
Yes. You must upgrade to the ICS Bootloader. Civato has a nice thread that contains a couple different ways to do it. Some other's have posted some "repair" methods if something goes wrong. (very small percentage). Don't forget to update your recovery package as well. ;)

Just make sure you get and write down your UID number before beginning. Do it in a safe place. You will need it to update bootloader, and also if something happens.

MD
[Acer Iconia A500] fdadda:
thanks Moscow for your replay. If I have understand well,b before made some mistake,the correct procedure t o do are:

install v8 bootloader with civato's guide with automatic flashing procedure using blackthund3r and in this case the cpuid and sbk the blackthund3r will give in automatic.

i must choose only from this 3 unlocked bootloader with recovery V8-pubA50._public_recovery.a500apx - V8-Thor_1.7.3_recovery.a500apx -V8-TWRP_2.1.3_ICS_recovery.a500apx

which do you suggest to me to download and install?

when the automatic flash finish i must change the recovery as you told me but which recovery do you suggest to me?

after install the right recovery i will install your new rom that it was already in sdcard

it is all correct?

sorry for the disturb
[Acer Iconia A500] Moscow Desire:
The Blackthund3r is the easiest to use. I myself have never used it. I did it the very old way when the new bootloader was in development.

As with Recovery, all 3 are very good recoveries. I hate to make a choice on which is best. I currently use Thor 1.7.3. Only because I am too lazy and busy to install Public Recovery. Next week, when I finish the rom, I probably will change. I have used both in the past. And they are good. I have not tried TWRP yet, but some people like it.(my instructions are specific to CWM 1.7.3 and Public Recovery)

And yes, once you install bootloader and recovery, then you boot into the recovery (hold PWR & vol-) until you see "booting recovery kernel", then release both.

The you can follow my install instructions as to "Wipes and Formats", then install rom.

If you have any questions, you may always post them here. There are some good 501 folks, and also 500 folks that can help.

Good luck. Remember, write you current UID number somewhere, (I also keep it in Notepad on the PC).

Check your PC Drivers to make sure they work when you plug in the tab.

MD
[Acer Iconia A500] Moscow Desire:
One more thing to remember. You "can't brick" an Iconia 500/501. No matter what happens, because of the way it was designed, there is always a method to get it running again. And believe me, I've bricked mine a couple of times. We have enough "un-brick" experience in these threads, you should not have to worry.

So relax, have a couple of beers. Load the Acer or Google drivers, make sure they work in APX mode, and do it.

So my advice, go out, get some beers, relax, and just do it! It's what I always do ;)

Oh, and I "expect" a report from you when you finish.

Reports

Thanks for the reports! I guess I will go ahead and deodex (Thanks Civato for your deodexing tool), then do a couple of the usual mods.

I still have a couple things to play with, for GPS.

How do you guys like the GPS? Is it working ok for you?

The theory behind the GPS mod, is that it more or less remembers the sats you were last locked on to. In theory. GPS Status locks onto them almost immediately. 3 of them anyhow. And still searches for others. Maybe that's good enough. The mod was for a 500, and the 501 uses a different radio. So I don't know if that's really an issue or not.

I'll toss another modded kernel without GPS mods, and see the difference. If there's a big difference, then I'll change it.

In the meantime, use GPS status and check GPS response. Also state your country when you post a report please (if country is not identified in your profile).

Just a quick report after 2 days running Evil Test :)

- No 3G drop

- No SOD

- Battery is good ( 8 hours in sleep state with 3G, Wifi, GPS on, Google sync... all take 8%)

- First GPS shot took forever to lock, after reboot it's locked quick as normal.

- Wake up quicker from deep sleep than 1.4

Tks MD again for ur great job :)
[Acer Iconia A500] Moscow Desire:
Well, its because you shouldn't do a restore of data when you change roms. It's sometimes possible, but mostly you get errors. You can restore apk's but data should not be restored.

TB is really only useful if you install the exact same rom again. Or just for backing up program apk's.

MD
[Acer Iconia A500] Moscow Desire:
There hear a couple of ways to do this. One, is when you install the rom. You can set the option 'toggle data media's in cwm, then format /data. This will wipe all info from the tab and basically leave it clean. Your ext SD card is safe. Then you can do your wipes and stuff, and install the rom.

The other method is to access the internal folders. You can do this from your PC, but be careful. Some of your current apps might be using this information.

MD
[Acer Iconia A500] tresed:
I guess that does not change too, as I did, with backup from recovery
[Acer Iconia A500] Moscow Desire:
Yeah, you will get the same result. Sometimes you can do it with some game data, but usually it only takes 1 small difference with roms, and you get errors.

Sometimes, apps store it in /data/media which doesn't get wiped. Like Oxford translation database. I only need to download the apk again.

MD
[Acer Iconia A500] grimm18:
hi md,

very good rom but as soon as oc mod added, sod returns.
[Acer Iconia A500] ultramag69:
That means you have the undervolt too low... SOD happens because the CPU isn't getting enough juice to wake up. You could try to raise the undervolt currency back towards normal but it will continue to SOD until it gets to the point where the CPU is getting enough of a jolt to wake properly...

Like this rom, very quick, a bit faster than A 5... GPS took 13minutes to get 1st lock, can't comment on next lock as I haven't done another lock yet. No SOD's yet but I only loded the rom last night before work, no GSM drops either. Everything seems to be working great and I like it a lot.

Good job MD, and thanks to Civato too.. :good::D
[Acer Iconia A500] Moscow Desire:
What OC Mod?????? There is none available for this test rom.

If you installed one of the older experimental OC kernels from some months ago, you will get SOD and 3g drop. That specific kernel was experimental and built from 500 source and was for Alex V only. Although the OC worked, it still suffered from SOD and 3g drop.

It's better you wipe and re-install the Test rom again. Don't be changing no kernels ;)

You might be able to fastboot flash boot boot.img via SDK's fastboot. You would have to take out the boot.img out of the Evil Alex Test rom though, and put it in the directory of fastboot.exe

MD
[Acer Iconia A500] Moscow Desire:
He threw in that OC expermental kernel that vache and EZTerry worked from 500 source. That's why it gets SOD and 3g drops.

Yeah, the GPS has never been a strong point of the iconia.

I played with a kernel with no GPS mod, but the results are still pretty much the same. Granted I live in one of those Soviet built cement apartment houses, so I have to be near a window to check GPS.

Typically I get 3-4, on a good night maybe 6 or 7 in about 1 minute.

MD

EDIT: I'll try out an unmodified stock boot.img just to compare. I don't use GPS that much. Besides, my phone has a 100 times stronger GPS radio anyhow.

I might just offer a couple of different kernel flashes so people can choose what works best for them.
[Acer Iconia A500] yassero:
you need to go on data/app & remove everything related to the app you are trying to restore i.e: .apk & .odex

Here is my feedback. My battery fully discharged after 26 hrs & 23 minutes. I was on 3G all that time & had around 2 hrs of Wifi tethering. That's excellent performance considering I use Lotus Notes push mail & I google sync on. I had some fluffy screen at beginning but after a couple reboots it went ok. I have not tested GPS & did not check the overnight power consumption.

So guys just flashed and having a problem with wi-fi it will not turn on. Just booting into cwm and wiping again, any other ideas would be appreciated...okay fixed had to reflash and change the recovery. The twrp recovery does not have a format system or format flex. We flashed a different recovery, thor`s and then were able to format and format flex which gave us a clean install!!!! Thanks Moscow for a nice rom!!

Hi again,

Re flashed to test rom, format b4 and after flashing to be shore of clean install, NO oc mod and still get SOD.

Did notice sod appeared after using ext. SD card.

Other than this, good test rom.

Thanks again.
[Acer Iconia A500] Moscow Desire:
Sorry to hear that. Have no reports of SOD yet or 3g drops after sleep.

Question? Are you using Titanium Back-up to restore any data or user data?

Question? You said you didn't have SOD until you used Ext SD Card. What do you mean by this?

Try this.

1. If you are using Titanium Back-up, don't use it. Download apps fresh from the market.

2. Copy your data from your Ext SD Card to your PC. Then format the SD Card (fat32 of course), copy only the Evil Alex Test.zip, go to CWM, wipes and formats, then install the rom. Run it for awhile and see what happens. Download only normal apps from the market. No Utility Apps like battery apps and such.

Also, What version of unlocked bootloader are you using? V8? And need to know which version of recovery you are using. (CWM, TWRP, Public Recovery).

MD
[Acer Iconia A500] grimm18:
hi again,

yes to titanium, and sorry, sod at random now.

using twrp with v7.

the restoring data thingy manualy i will need to look up.:silly:

will use my spare 32gb micro sd card to reflash. (class 4)

thanks again
[Acer Iconia A500] Moscow Desire:
It's no problem ;)

I think The TB data restores might be messing things up. Usually, TB is only good for 2 things. Backing up APK's so you don't have to download them again (especially if you don't have wifi), and backing up Data (but only if you install the exact same rom again). You also must be careful how old the apks are. They may be HC apk's (old ones) and might not run correctly on ICS.

V7 bootloader is fine. Not sure about TWRP as I never used it before. Personally I prefer CWM or Public Recovery as they have more options. (TWRP doesn't have format /system or /flexrom, and maybe a couple others. But the rom install should be formatting both of these on install. I said.....should)

One more question, do you have the Android SDK installed on your PC? The reason I ask, is that it's a lot easier to "fastboot" a boot.image, rather than re-install the entire rom. It's how I test kernels. Of course this only works if you don't have to add or delete certain modules of course. Just some advice for the future.

Hi MD! Sorry to bother you... when could we expect deodexed version? :)

Sorry but i really like acer ring ;) Thanks for your great job btw!
[Acer Iconia A500] Moscow Desire:
I can only guess something with accelerometer/gyro isn't quite in order. The rom itself is stock origin odex. So I didn't mess with anything concerning those features.

I can tell you that about 10% or less of tabs (500/501) suffer a similar issue, in some cases they don't work at all. And it all happens when upgrading to ICS. There's all types of "village fixes, although they really don't fix anything in my opinion. Things like starting the tab with rotation lock on, etc. Eventually for most, the issues just magically go away after some days. Not sure why. And it also happens to ICS stock OTA updates as well. Check the Q&A forum. You might find some of these "village fixes".

The only other thing I can think of, is if you restored Data from either Titanium Backup or via CWM. APK's are generally ok, but Data is a big no-no unless coming from an exact same rom.

Does this happen after initial install of the rom? Or after installing apps? Try a fresh install (wipes and formats), then check gmail. See if it happens. It's possible a rogue app or one that isn't compatible with this version of ICS.
