[TouchPad General] dperls:
I've had CM7 a3.5 on for a few days and set up my android install pretty much exactly how I want it however I'm looking to try the Xron flavor of the rom. I know the install instructions say you need a full wipe, but I've seen a lot of reports saying that flashing over it works as well.

Anyone have any experience with it?
[TouchPad General] chicle_11:
I installed it with just a wipe cache/dalvik cache. I did the wipes twice. It's been great so far.

Read the posts though , some have had troubles. Make sure you have a backup!
[TouchPad General] iamsamsamiam:
Sure you "can" just install over but the true question is "should" you. If you just install over a3.5 you wouldn't see the same benefits as coming from a full wipe.

Hey guys,

i have a problem when building 4.0.3 from source. When i flash the fresh compiled

OTA package to my device, the device ends in a bootloop stuck at the google logo.

I don't know whats going wrong. Can it be a kernel problem? I have tried different 4.0.3 kernels from the dev section, but the result is the same.

The device is a GSM device with PRIMEKK15 unlocked bootloader and I9250XXKK6 baseband.

After pulling the latest 4.0.3 sources with repo and setting up the proprietary files i'have compiled the system without errors:

~/android/4.0.3$ . build/envsetup.sh
~/android/4.0.3$ lunch full_maguro-userdebug
~/android/4.0.3$ make -j4 otapackage

I really don't understand what i am doing wrong :confused:...

Thanks for any suggestions or answers.
[Galaxy Ace S5830 General] elporcus20:
My phone is L band, so I installed the 2.3.6 rom (the russian one) two days ago and reflash with the L modem from the 2.3.4 version, inicially the device went well, but since this morning the phone is very slow, i have lag after unlock, in the menus and when i run apps.

i don't know if this is because i flash with a modem from a previus version, or is just that the version is unstable, i don't even root the phone yet so...

...can anyone tell me why phone is so slow?
[Galaxy Ace S5830 General] Prashanthme:
Did u wipe data/Factory reset after flashing??????????
[Galaxy Ace S5830 General] litotamez:
Ok some advices do a cache cleaning....other thing is...do you do a wipe data...? And my last advice root the device with ginger ace root.zip.. Hope it works
[Galaxy Ace S5830 General] elporcus20:
yes i do it several times
[Galaxy Ace S5830 General] litotamez:
Mmm maybe the best solution is return to 2.3.4
[General Questions and Answers] opus22:
I am trying to install the official ICS update to my Nexus S.

I have done a factory reset on the phone and the specs are:

Android Version 2.3.6

Build : GRK39F

Baseband: I9020AUCKF1

When I try to update it it says it failed verification and aborts.

I downloaded what i believe is the official update file and moved it to the internal storage without modifying it at all.

any body have any ideas ?

Thanks In Advance

[Samsung Epic 4G Touch] sjsharksfan420:
Im not able to post in the dev side yet, still working on my first 10 posts. So.. a tiny history, I am comming from 2+ yrs experience with WebOS and pre- & pre2. I am very familiar with customizing with preware, using all the patches & OC kernels.

So, what I have noticed, although webOS & Droid are both Linux based, it seems that they are fairly different when it comes to customizing.

This is my issue, I have a galaxy S2 epic 4g touch (sprint). When I got it, it was on EG30 (2.3.4). I was able to root and flash LOS and didnt have any issues. When the 2.3.6 update was pushed out, I didnt have a chance to unroot, so I ended up having to wipe/restore back to 2.3.4, then I tried to reroot, I got the no wifi and bootloop. I wiped and resotred again, all was ok, and I tried to root manually with the e4gtauto method, that I found for the EK02 stock system. Well, all was perfect, until just ran a backup with titanium, not restore, but just a back up. Is that my problem? Having titanium installed when rooted? I have been trying to follow QBKing77's processes, but need to just have a confirmation on the best process to root EK02 SPH-D710 on 2.3.6

Thanks,

sj
[Samsung Epic 4G Touch] sfhub:
Titanium and root is not going to cause the issue you describe.

For some reason going from los to stock sometimes has wifi issues. I suggest you backup, then odin the eg30 factory restore in my sig

When that is done, do a ##786# reset from dialer and let the hamds free activation take place.

Verify wbether wifi works. If it does apply the ek02 ota update.

Then start restoring your data backup.
[Samsung Epic 4G Touch] sjsharksfan420:
Thanks for the response. I have been able to get my phone updated to ek02 with out any issues. As of right now, it is a fresh install with the ota update ran to get to 2.3.6, I have all my apps/data restored. The only thing I want to do is root, install latest cwm, SU, and busybox. When I tried to manually root, it worked perfect, so it seemes, I didnt have any problems until the next morning. I was wondering too, do I need to be rooted already to do a nandroid backup?

sj
[Samsung Epic 4G Touch] sfhub:
You need cwm to do a nandroid backup. Technically you do not need "root" to have cwm, but practically if you have cwm you'll probably have added root as well.

I guess I don't understand what "problem" you are seeing 1-day later. You said you got by the wifi problem. Any chance your problem is related to the restore? Are you restoring only user elements or system elements as well?
[Samsung Epic 4G Touch] sjsharksfan420:
The wifi issue the ive seen I thought was a common problem with the latest update, but ive found that it is not connected to the bootloop problem. The wifi issue that ive seen is that it stops functioning until you restore back to stock. That is what I have done, reinstalled the stock ROM from sprint, updated to 2.3.6, then rooted. (currently not rooted) but every time ive tried, it seems to be unstable and I end up in a bootloop..
[Samsung Epic 4G Touch] sjsharksfan420:
What I want to do is root as stable as possible. I dont have to, but from my experience, the devices are much better when rooted with the added functionality that you have access to.

Question about nandroid backups, does that type of back up take a snapshot of how your device is at the time of backup? Does restoring a nandroid backup put your phone back to the exact state it was when backed up? Root and all with apps and settings?

I want to be able to create a backup where I dont need to manually fix all my apps & settings, or is that even possible too?

Thanks for the help.. :)

sj
[Samsung Epic 4G Touch] sfhub:
If you've rooted using the Auto Root package, there is no chance that is causing your bootloop (nor your wifi problems). Other root methods which involve a new kernel might cause something like that, but not for the general case or many people would be complaining.

---------- Post added at 02:03 AM ---------- Previous post was at 01:59 AM ----------

I didn't re-read the whole thread to see what root method you used, but that is one of the reasons the Auto Root package exists. A minimalist approach to rooting that uses your existing stock kernel/rom.

It dumps the images of your system/data/cache/kernel partitions. It will restore everything to just like it was, except for the modem, which isn't backed up.
[Samsung Epic 4G Touch] sjsharksfan420:
Thanks again for the responses. So, if I am rooting with the autoroot tool, what can be causing my no wifi & bootloop issues? I have tried with a fresh restore (to stock 2.3.4) and then root, and I have also tried a rooted EK02 ROM, both become unstable after resetting..

Im kinda bummed that I cant figure this out.

After it being super simple to root/oc 2.3.4, im frustrated that it is so different now.. :/

sj
[Samsung Epic 4G Touch] sfhub:
Different kernels and OC are potential culprits. With the bootloop, I would think my first suspect would be OC/undervolt/etc. Not all CPUs can OC to the same speed and be stable.

So you factory restore to EG30 then wifi is working and no bootloop? Let it sit like that for 2 days. Then install root using auto root. Again let it sit for 2 days. Then finally start adding your other stuff one by one until wifi and instability gets introduced.

I can guarantee you 100% that rooting using Auto Root is not causing your wifi and bootloop issues. I'm saying this because of analysis of the changes Auto Root makes. It is just adding 3 files, which are mostly DORMANT unless you use them.

Concentrating on root as the cause of your issues is a waste of time. You need to look at the other changes.
[Samsung Epic 4G Touch] sjsharksfan420:
Awsome, thanks for the response again. Should I install acs recovery or cwm to do a nandroid backup? I want to make sure I can restore easier than having to redo everything everytime, or is that expected to need to do everytime I "play" with this type of customizing.

sj
[Samsung Epic 4G Touch] sfhub:
Both are fine. Nandroid should get you back to where you started as long as you aren't doing modem changes.
[Samsung Epic 4G Touch] sjsharksfan420:
does that mean as long as I back up stock EK02 2.3.6 before root, or does that mean I should nandroid backup at EG30 2.3.4 before root?
[Samsung Epic 4G Touch] sfhub:
Assuming you want to end up at EK02, I would make the cwm/nandroid backup immediately after applying the EK02 OTA update on top of EG30, before adding your own items back.

Run it completely stock for a day or two (however long it too in the past for the wifi/bootloop problem to crop up) If it doesn't show up, then start adding your stuff back in a few at a time. Once it shows up, you'll be able to isolate which most recent change caused the issue.
[Samsung Epic 4G Touch] sjsharksfan420:
Awesome, thats what I figured, but I just wanted to be sure, I'll chime back in after I start if I run into problems.

Just to clarify, I cannot back up when I have it all set up with my apps/settings to where if I get a bootloop or something I can just restore with apps/settings restored? or is installing apps manually the only way to get the device back to how you like it for day2day usage?

sj
[Samsung Epic 4G Touch] sfhub:
You can make multiple backups, one at each stage, and restore to that point. The only thing you can't restore is the modem (you can flash the modem by hand, just not from a nandroid backup), but assuming you can get a stock EK02 which doesn't have any issues, then it doesn't matter as you won't care to go back to EG30, so your nandroid backups of EK02 should serve you fine to figure out what is causing your issue.
[Samsung Epic 4G Touch] sjsharksfan420:
right on, thanks sf, moving from webOS to android will be a breeze with all of the great devs and such to ask questions. i was fairly impressed on how the development community for webOS was so open and friendly, i am glad to see that it is the very same way over here too! :)

sj
[Samsung Epic 4G Touch] sjsharksfan420:
Hi SF, i wanted to clarify my steps before i run through them. So i am currently running stock EK02, unrooted with plenty of apps currently installed. (do i need to be rooted to install cwm and then run nandroid backup?)

I was thinking my process is as follows:

1 - Backup my app list (I've found Ultimate Backup Pro is very nice)

2 - Remove external SD card and flash back to stock (outta the box) EG30/2.3.4

3 - Update to EK02/2.3.6

4 - Remount SD card, install CWM5, run nandroid backup. Is ACS recovery better?

5 - Root, wait 1 day

6 - Install SuperUser & BusyBox

7 - Start restoring apps a few at a time

? Does it help to reboot after each install for any reason. Also, are apps that require root access the usual reason that cause the wifi/bootloop issues, or can any app free or paid cause the same problems?

Again, i totally appreciate the info you have explained already! :) oh, btw, Merry Christmas! :)

see ya

[Samsung Epic 4G Touch] sfhub:
Here is what I would suggest

[Samsung Epic 4G Touch] sjsharksfan420:
Hi SF, qq for when I run step #3. When navigating in Odin to run the SPH-D710.EK02_CL704398_NODATA-OneClick.exe file, do I use PDA for that too? I assume so, but just want to make sure that I do not need to run that file from the Bootloader, phone or CSC boxes.

sj
[Samsung Epic 4G Touch] sfhub:
I think in your case it is better you use the full version that resets your user data. You've already mixed and matched a few different setups and have had problems in the past.

There is no "PDA" slot for the OneClick versions. You just double-click, plug your phone in, and press start. There aren't any options to choose.
[Samsung Epic 4G Touch] sjsharksfan420:
ok, sweet, I plan on starting the process this evening. As always, I will post if I have issues or further questions. btw, thanks again for being so speedy with your responses.. :)

[Samsung Epic 4G Touch] sjsharksfan420:
gotta put my rooting on pause for a minute.. gonna wait till I have a few days available to be able to run through the steps without very many interruptions if any if I can help it.. I will most likely work on it within the next few days and will post my experience here. I am hoping it will be as easy as pie.. :)

sj
[Samsung Epic 4G Touch] sjsharksfan420:
hi sf, I am wanting to run through rooting my device later this evening. I plan on running the file that will wipe my data. I do still have one other clarification needed, I am currently running fully stock EK02 for 2.3.6, I haven't run any scripts nor rooting apps. My question is do I need to flash back to stock 2.3.4? Or do I run the .exe file to flash back to stock EK02 2.3.6 from where I am at? Also, seeing as how I haven't rooted yet since restoring 2.3.4 and updating OTA to 2.3.6, would it be different for me to uninstall all my apps, then root 2.3.6? I don't mind wiping the data, but I just was curious if that made a difference or not..

Either way, I will be starting later this evening if all goes as planned. :)

sj
[Samsung Epic 4G Touch] sfhub:
Not necessary.

EK02 ODIN one-click in my signature will bring you directly to full EK02 (Modem, Kernel, ROM) and reset user data assuming that is the version you chose.

You could do either way, but I think starting clean would be the best for your situation (meaning run the EK02 ODIN one-click that resets your data, do a ##786# reset the reset NVRAM, Use Auto Root Option A to root, Option C to install EK02+CWM, run it a little bit like that, then restore your apps a few at a time.
[Samsung Epic 4G Touch] sjsharksfan420:
hey sf, i have another question about bouncing back and forth with modem versions. i am wanting to root my EK02, but now EL26 is out and looks like its a much better modem version. what do you think is best? qbking77 from the ac syndicate team ran some modem tests and they were quite different..

sj
[Samsung Epic 4G Touch] sfhub:
The experience will be different for everyone. Some will say better, some worse, some will say the same.

My advice is to load up all the modems in my signature onto your /sdcard.

Then boot into CWM and you can switch between modems literally in less than 2.5 minutes, including reboot times.
[Samsung Epic 4G Touch] sjsharksfan420:
thanks sf, i plan on restoring to stock ek02, root (su, bb, cwm, ect), backup, save modems in folder on sd card, then playing with the modem update, then start restoring my apps/data.

Once i get everything running without bootloops while staying rooted, i can run another backup at thay point, and with having that nandroid & all the modems backed up on sd card, i should be able to restore back to that backup with apps and stuff minus the modem right? i want to be able to create an "image" of my phone when i have it fully customized. If i understood your previous explanation on that, everything except for the modem gets backed up with nandroid, correct?

sj
[Samsung Epic 4G Touch] sfhub:
You got it all down.
[Samsung Epic 4G Touch] sjsharksfan420:
awesome! you made it extremely easy to understand, i appreciate it greatly.. :)

sj
[Samsung Epic 4G Touch] sjsharksfan420:
Just got done with the restoring stock ek02, root, cwm. Going to run a nandroid backup, then rest it overnight, then tomorrow have fun installing all my apps back.. :)

I'll keep ya posted..

sj
[Samsung Epic 4G Touch] sjsharksfan420:
Everything is running perfect now! Still restoring a few apps at a time, all is perfectly smooth though.. :)

sj
[Samsung Epic 4G Touch] sjsharksfan420:
Hi SF, ok, so I have root, SU, bb, cwm5, ect, and I am running very stable as far as I can tell. I did start getting a force close for com.android.phone (or something, plus 1 other one) and I noticed that I had my internal SD card pretty full. So I moved the largest apps to external SD card, and the force closes are gone.

Now, since I am now rooted stable, what next? I had JRummy's ROM Toolbox, and I also tested ROM manager by clockwork. What is the better of the two? Or is there another better app for current ROMs?

The reason why I ask is because I feel like having both installed together might have caused my wifi/bootloop issues. I am using a samsung galaxy s2 epic 4g touch from sprint, and both of the apps i mentioned, even though they've been updated recently, I dont remember seeing that my device model was listed as being compatible. Is it better to flash ROMs with a pc, or since I'm rooted with cwm5, I can just apply or remove them on device?

Also, I have the EK02 & EL26 modems from the links in your signature on my SD card, do I just boot into recovery, then navagate to the modem and apply file through cwm?

Thanks for your help

sj
[Samsung Epic 4G Touch] sfhub:
Re rom manager and toolbox you should ask as separate question. I don't use either but from reading other peoples' comments it didn't sound like rom manager really supported our phone

Re modems in my signature, just make sure kernel+recovery you have installed is ek02-based or newer, for example ek02+cwm, el13+cwm, el26+cwm in the auto root package. Then flash as you described.

One other thing, since you have it working well, make a cwm/nandroid backup and archive it on your pc
[Samsung Epic 4G Touch] sjsharksfan420:
Hi sf, I got my modem updated to EL26, so far it seems to be more stable, but when i ran a speed test, to me, it didnt seem as drastically different as qbking77. But it varies by device and test, so im not concerned about that, i want stability anyways.

which ROM seems to be the best?

Also, do i need to do anything special in order to install themes?

sj
[Samsung Epic 4G Touch] sjsharksfan420:
hi sf, i have another qq, sorry for all of the noob stuff. I ran through the process that we discussed before, I am running very stable and "snappy" since even without an OC kernel, tegrak can oc up to 1.45ghz. So, the ONLY thing left for me to do is removing that freakin carrier IQ. So, I have the latest AOSPmod ROM on my SD card, and I am pretty sure I know how to install, my question is this though, since its recommended to do a factory/wipe along with dalvik cache clear before ROM install, is it expected to have to reinstall all apps when you "bounce back & forth" between ROMs? If I ran a nandroid restore, will that just overwrite the ROM that I would have just installed?

sj
[Samsung Epic 4G Touch] sfhub:
Yes, it is best to reinstall apps from backups when switching ROMs (and NOT restoring the backup of the system elements)

Restoring from your CWM/Nandroid backup will completely get you back where you started, except for the modem. No need to wipe first.
[Samsung Epic 4G Touch] sjsharksfan420:
i see, so if/when a custom ROM is flashed, then i should still use my app back up app to find and reinstall my apps that i use every day at least? (in my case, i am using ultimate backup) so, if youre like me and like to get my phone the way i like it and leave it as is, you wont like bouncing from ROM to ROM?

sj
[Samsung Epic 4G Touch] sfhub:
Basically if you are upgrading to a different version from the same ROM author you are probably safe not clearing out your user data by doing a factory reset.

If you are upgrading to a different ROM altogether (and especially if they have framework changes), it is best to do a reset, then restore just apps.

Some pople just skip the step of factory reset clearing out user data, and only do it if issues arise.
[Samsung Epic 4G Touch] sjsharksfan420:
thanks for your responses and time sf, you really have made all of this very straight forward and easy to follow. I will try installing without a wipe first, hopefully it will be smooth.. :)

sj
[Samsung Epic 4G Touch] sjsharksfan420:
hey sf, I'm just about ready to pull the trigger on the flashing of the Epic4gAOSPmod2.6.2 ROM, but before I do, I was wondering if I don't do a wipe first (clear user data), should i try the deodexed version rather than odexed since the deodexed allows for the sprint apps to be reinstalled? I am going from completely stock 2.3.6 with el26 modem (rooted, su, bb, cwm ect..). Also, the ONLY thing i need is to remove CIQ as the stock kernel can OC to 1.452g. Is there a way to remove CIQ manually?

sj
[Samsung Epic 4G Touch] brianhot1:
I went through the same exact problem,my issue is now fixed what you need to do is flash the kernel thats the problem,follow this link and pick which recovery if you have cwm or acs,once you download the ZIPPPPPPP from phone you would have to move file over to root of sd card.That means the first file system on your sd card or internal sd card,boot into recovery by holding volume up and power then select option to install from zip then you should have option for internal memory or sd card select either one you moved kernel ZIP file to,after doing so select zip file if you have cwm to select would be the house button,it should flash new kernel then try wifi again it should fix problem guaranteed
